奶片包装机主要机构及作用

Main mechanism and function of milk film packaging machine

1、机身：机身主要由机座和墙板组成，为本机主体，借以支承所有其它零部件。

1, fuselage: the fuselage is mainly composed of frame and wallboard, which is the main body to support all other components.

2、铝塑卷筒：包括铝箔卷筒和塑片卷筒两部分。卷筒主要由筒体、里外定子、制动圈和调节螺母等组成，筒体两端用滚动轴承支承在支承轴上，为卷筒的转动部分，当牵引塑料薄膜或铝箔时，即带动装在卷筒上的卷料自由转动。定子分里外定子，滑套在筒体外圆柱面上，并借固定螺钉固定在筒体的任意位置，用以安装固定不同宽度的卷料。制动圈套装在筒体的里端外圆柱面上，并固定在支板上，为卷筒的静止部分，用以制动筒体。拧紧或退出制动圈外圆周上4只调节螺钉，可增加或减少对筒体的制动力，使被牵引的薄膜或铝箔获得必要的张紧力。调节螺母旋装在支承轴并套装在筒体的外端内圆柱面上，并用1台轴承与铜体连接，在筒体旋转的情况下，转动调节螺母，可使筒体实现轴向移动，用以调节郑料的横向位置。支承轴固定在支板上，支板固定在机身上，构成卷筒的支承主体。

2, aluminum plastic drum: including aluminum foil drum and plastic drum two parts. The reel is mainly composed of the cylinder, the inner and outer stator, the brake ring and the adjusting nut. The two ends of the barrel are supported on the supporting axis with rolling bearings, which are the rotating parts of the reel. When the plastic film or aluminum foil is drawn, the rolls are freely rotated. The stator is divided into the inside and outside stator, and the sliding sleeve is arranged on the cylindrical surface of the cylinder, and is fixed at any position of the cylinder by a fixed screw, so that the coil material with different width can be installed and fixed. The brake ring is arranged on the outer cylindrical surface of the inner end of the cylinder body and is fixed on the supporting plate, which is used as a braking cylinder body for the stationary part of the reel. Tightening or withdrawing 4 adjusting screws outside the circumference of the brake ring can increase or reduce the brake force to the cylinder, so that the necessary tension force can be obtained by the towed film or aluminum foil. The adjusting nut is mounted on the supporting axis and is mounted on the cylindrical surface of the outer end of the barrel and is connected with the copper body with 1 bearings. When the cylinder is rotated, the adjusting nut can be rotated to make the cylinder move in axial direction, so as to adjust the transverse position of the Zheng material. The supporting shaft is fixed on the supporting plate, and the supporting plate is fixed on the fuselage to form the supporting body of the drum.

3、吸塑加热器：吸塑加热器主要由弧形热盒、8支远红外管、支承轴和定位器等组成，弧形热盒上端铰装在支承轴上，并可绕轴摆动，工作时靠近吸塑滚模幅射加热料薄膜，不工作时摆离吸塑滚模。远红外管安装在热盒内，为本机构的发热元件，通过电子调压器调节远红外管两极电压来调节发热量，使薄膜获得必要的软化温度，支承轴固定在机身上，用以支承热盒，定位器由弹簧拉杆和挡块组成，分别安装在热盒和机身上，为热盒工作位置定位之用。

3, suction heater: the suction heater is mainly composed of arc heat box, 8 far infrared tube, supporting shaft and locator, etc. the upper end of the arc heat box is hinged on the supporting axis, and can swing around the shaft. The far-infrared tube is installed in the heat box. It is used as the heating element of the mechanism. Through the electronic voltage regulator regulating the two pole voltage of the far infrared tube, the heat can be adjusted to make the film obtain the necessary softening temperature. The supporting shaft is fixed on the fuselage to support the heat box. The locator is composed of spring rod and block, which is installed in the heat box and the fuselage, respectively. For the position of the working position of the heat box.

4、吸泡滚模：本机关键部件，它与吸塑加热器、热封网辊相配合，先后完成泡罩成形、热压密封等工序。该部件主要由滚模、滚模轴、月形阀板以及真空和冷却系统组成。 滚模用硬铝合金制造，表面分布着泡窝，窝底钻有微孔，通过月形阀板与真空吸气管相通，使通过吸泡区段的塑料薄膜经加热器幅射加热软化后，被吸成泡罩。滚模套装在滚模轴上，用螺母固紧，变换药品时，只要打开滚模密封端盖松下螺母，即可更换滚模。滚模轴芯设有进、排水道。冷却水通过水道进入滚模，起到冷却作用。

4. Suction and roll molding: the key parts of the machine are matched with the plastic suction heater and the heat sealing roller, and finish the process of blister forming and hot pressing. The component is mainly composed of rolling die, rolling die axis, moon valve plate, vacuum and cooling system. The roll die is made of the hard aluminum alloy, the surface is distributed with the bubble nest, the bottom of the nest is drilling with micropores, and the plastic film through the heater is heated and softened through the heating of the heater through the vacuum suction tube, and it is sucked into a bubble cover. The rolling mould is sleeved on the rolling mould shaft and is tightly fixed with the nut. When changing the medicine, the rolling die can be replaced by opening the sealing cover of the rolling die and the nut of the Panasonic. The shaft core of the roll die is provided with an inlet and a drainage channel. The cooling water enters the rolling mold through the water channel and plays a cooling role.

5、加料器：它主要由料料、料槽、盘刷、滚刷及直流电机等组成，料料用于储存药品。开启闸板，药品自行进入料糟，然后借助三只绕垂直轴转动的盘刷将药品刷入已成形的泡罩内，三只盘刷呈行星迹转动，以提高加料器的填率；滚刷绕水平轴按顺时针方向转动，置于加料器的出口，将薄膜上未能进入泡罩的药品刷入泡罩或刷回加料器。

5, feeder: it is mainly composed of material, material trough, disk brush, rolling brush and DC motor, etc. it is used for storing drugs. When the gate is opened, the drug enters the material by itself. Then the medicine is brushed into the formed bubble hood with three disc brushes rotated around the vertical axis, and the three disk brushes are rotated on the planet track to improve the filling rate of the feeder; the roll brush is rotated in clockwise direction around the horizontal axis and placed in the outlet of the feeder, and the film on the film fails to enter the drug of the bubble cover. The product is brushed into the blister or brush back to the feeder.

6、热封网纹辊：热封网纹辊与吸泡滚模配合，完成薄膜与铝箔的热压密封工作，热封网纹辊主要由网纹辊压缩弹簧、离合装置和支架等组成，网纹辊体内装有六只加热管，工作时加热网纹辊，然后使进入热封的铝箔表面热熔胶加热熔化，网纹辊两端的方块轴承去随在支架滑槽中，用压缩弹簧加压网纹辊。工作时，使网纹辊靠近吸泡滚模，使进入热封的薄膜与加热的铝箔实现热压密封。离合装置包括凸轮和拨叉，凸轮按逆时针方向旋转，经拨叉使广场轴承右移，反向压缩加压弹簧，网纹辊便离开吸泡滚模，当没有塑料薄膜和铝箔进入或不同时进入热封时，网纹辊与吸泡滚模必须避免接触，否则将可能损坏网纹辊和吸泡滚模。

6. Hot sealing reticle roll: heat sealing reticule roll and foam drawing die to complete the hot press seal of film and aluminum foil. The hot seal reticulated roll is mainly composed of the reticulated roll compression spring, the clutch device and the bracket. The reticulated roll has six heating tubes in the body, and the reticulated roll is heated at work, and then the hot melt adhesive on the surface of the aluminum foil into the heat seal is made. Heating and melting, the square bearing at both ends of the anilox roller is used in the bracket chute, and the compression spring is used to pressurize the anilox roller. When working, the anilox roller is close to the suction and rolling mould, so that the heat sealed film and the heated aluminum foil can be heated and sealed by hot pressing. The clutch consists of a cam and a fork. The cam is rotated in the direction of counterclockwise, and the square bearing is moved right by the fork, and the pressure spring is compressed by the reverse compression. The reticulated roll will leave the foam model. When there is no plastic film and aluminum foil entering or not entering the heat seal, the mesh roll and the foam roll die must be avoided, otherwise the net will damage the net. Roll and foam drawing die.
