Description
Technical Field
[0001] The invention belongs to the technical field of plastic bag film blowing machines, in particular to a plastic bag film blowing machine with an automatic winding function. Background Art
[0002] Plastic bag film blowing machine is a kind of equipment used to produce plastic film, especially the common polyethylene (PE) film. The main function of the film blowing machine is to heat and melt plastic particles (usually plastic resin) and blow the molten plastic into film through air flow. The film can be used to make various types of plastic bags, packaging materials, etc.
[0003] For example, the "A plastic bag film blowing machine with automatic winding function" with publication number: CN118386533B includes a base, the upper surface of the base is symmetrically fixedly connected with a film blowing machine body and a winding seat, the upper surface of the base is located between the film blowing machine body and the winding seat and is fixedly connected with a bracket, and the winding seat and the bracket are provided with a clamping assembly for clamping and stably guiding one end of the film; the movement of the movable seat realizes the docking between the sliders on the two limit rods, completing the clamping of the cooled and shaped film, and the subsequent continued movement drives the slider to pull the two ends of the film apart, so that the film is spread out flat, and is pulled upward to be clamped between the two pressure rollers, realizing the traction operation of the film in the initial stage, ensuring the stability of the film during the processing and the accuracy of the shape, while avoiding the workers from being exposed to hot air and residual heat on the film during operation, reducing the risk of scalding, and improving the safety during the production and processing process.
[0004] However, in the prior art, although this type of plastic bag film blowing machine can prevent workers from being exposed to hot air and residual heat on the film during operation, reduce the risk of scalding, and improve the safety of the production and processing process, it is lacking in the replacement of the winding roller after the winding is completed. Since this type of plastic bag film blowing machine does not have a structure for assisting the replacement of the winding roller, this will result in the need for workers to move the winding roller after the plastic bag is rolled up, or replace it with the help of lifting or transfer equipment. During the transportation process, the winding roller will become very heavy due to its own weight plus the weight of the plastic bag. Manual transportation alone will not only increase the labor input cost, but also increase the risk of safety accidents. Disassembling and assembling it with the help of lifting or transfer equipment will reduce the efficiency of replacing the winding roller, thereby reducing the efficiency of plastic bag production.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. In the present invention, the plastic bags produced by the film blowing machine body are blown out through the discharge pipe. After the plastic bags pass through the clamping plate, the motor A is turned on. The motor A drives the bidirectional screw to rotate. When the bidirectional screw rotates, it drives the movable plate to slide inside the horizontal plate, thereby driving the slide bar A and the clamping plate to move until the clamping plate clamps the plastic bag. The plastic bag is then passed through the middle of the limit shaft A and the limit shaft B. At this time, the plastic bag is passed through the bottom of the limit shaft D, and then through the top of the afternoon inner shaft C, and finally wrapped around the surface of the winding roller. At this time, the winding roller is connected to the transmission mechanism to complete the winding of the plastic bag. When it is necessary to disassemble and replace the winding roller after winding is completed, just push the connecting rod. After the connecting rod is away from the clamping block A, the fixed plate will rotate due to the torsion force of the torsion spring. After the fixed plate is turned away, open the electric push rod. The electric push rod will drive the lifting block to slide downward inside the aggregate seat, thereby driving the winding roller to move downward. After the bottom of the winding roller is attached to the guide block, the winding roller will move out of the top of the lifting block along the guide block, thereby completing the disassembly of the winding roller after winding is completed, avoiding the need for staff to carry it or use lifting or transfer equipment when disassembling the winding roller.
[0018] 2. In the present invention, the newly produced plastic bag is passed through the top of the cooling shaft B, and then through the middle of the cooling shaft A and the cooling shaft B, and finally through the bottom of the cooling shaft A upward. At this time, the spring B will drive the connecting block A to slide inside the side plate, and the connecting block A will drive the cooling shaft B to move toward the cooling shaft A, so that the plastic bag is clamped, and then the water pump is turned on. The water pump will inject the coolant in the water tank into the water storage plate through the connecting pipe, and the water storage plate will transport the coolant to the cooling shaft A and the cooling shaft B through the water inlet pipe A and the water inlet pipe B. At this time, the cooling shaft A and the cooling shaft B will cool the plastic bag. As the coolant continues to flow, the coolant will flow into the cooler through the outlet pipe A and the outlet pipe B. After the cooler cools the coolant again, it will flow back to the water tank through the connecting pipe, thereby completing the cooling of the plastic bag.
[0019] 3. In the present invention, the water-cooled plastic bag can be cooled by a fan. At this time, the fan will blow external air to the plastic bag through the air inlet, and the filter plate will filter the flowing air, thereby avoiding the situation where dust or impurities in the air adhere to the surface of the plastic bag, thereby improving the quality of plastic bag production. When the lever is moved, the lever will drive the block B to slide inside the bracket. After the block B is away from the slot, the filter plate can be pulled out of the slot. After a new or cleaned filter plate is inserted into the slot, the block is released. At this time, the block B will be moved upward by the elastic force of the spring B. After the block B is stuck in the slot, the filter plate can be fixed in the slot, thereby completing the replacement of the filter plate, and at the same time, it also has the effect of facilitating the disassembly and cleaning of the filter plate.

[0035] In this embodiment, the plastic bag produced by the film blowing machine body 101 is blown out through the discharge pipe 102. After the plastic bag passes through the clamping plate 111, the motor A105 is turned on. The motor A105 will drive the bidirectional screw 106 to rotate. When the bidirectional screw 106 rotates, it will drive the movable plate 108 to slide inside the cross plate 104, thereby driving the slide bar A109 and the clamping plate 111 to move until the clamping plate 111 clamps the plastic bag, and then the plastic bag passes through the middle of the limit shaft A113 and the limit shaft B114.

At this time, the cooling shaft A201 and the cooling shaft B202 will cool the plastic bag. As the coolant continues to flow, the coolant will flow into the cooler 213 through the water outlet pipe A214 and the water outlet pipe B215. After the cooler 213 cools the coolant again, it will flow back to the water tank 208 through the connecting pipe 216, thereby completing the cooling of the plastic bag.

After the block B306 is away from the slot 303, the filter plate 302 can be pulled out of the slot 308. After the new or cleaned filter plate 302 is inserted into the slot 308, the block is released. At this time, the block B306 will be moved upward by the elastic force of the spring B207.

[0041] The use method and working principle of this device: when it is necessary to clamp and limit the plastic bag just produced, first blow out the plastic bag produced by the film blowing machine body 101 through the discharge pipe 102, and after the plastic bag passes through the clamping plate 111, turn on the motor A105, the motor A105 will drive the bidirectional screw rod 106 to rotate, and the bidirectional screw rod 106 will drive the movable plate 108 to slide inside the cross plate 104 when rotating, thereby driving the slide bar A109 and the clamping plate 111 to move until the clamping plate 111 clamps the plastic bag, and then the plastic bag passes through the middle of the limiting shaft A113 and the limiting shaft B114, and then the plastic bag passes through the bottom of the limiting shaft D120, and then passes through the top of the afternoon inner shaft C, and finally winds around the surface of the winding roller 130, and then the winding roller 130 is connected to the transmission mechanism, The winding of the plastic bag is thus completed. When it is necessary to disassemble and replace the winding roller 130 after winding is completed, it is only necessary to push the connecting rod 129. After the connecting rod 129 is away from the block A125, the fixing plate 128 will rotate due to the torsion force of the torsion spring 127. After the fixing plate 128 is turned away, the electric push rod 124 is opened. The electric push rod 124 will drive the lifting block 123 to slide downward inside the collecting seat 115, thereby driving the winding roller 130 to move downward. After the bottom of the winding roller 130 is attached to the guide block 122, the winding roller 130 will move out of the top of the lifting block 123 along the guide block 122, thereby completing the disassembly of the winding roller 130 after winding is completed, avoiding the situation where the staff needs to carry it or use lifting or transportation equipment when disassembling the winding roller 130.
[0042] When the tension of the plastic bag needs to be adjusted, the synchronous motor B117 only needs to be turned on. The synchronous motor B117 will drive the gear 118 to rotate. The gear 118 will drive the rack 121 to move downward inside the material collecting seat 115 when rotating, and the rack 121 will drive the moving block 119 to move downward inside the material collecting seat 115, thereby driving the limit shaft D120 to move downward, and the limit shaft D120 will press the plastic bag downward when moving downward, thereby adjusting the tightness of the plastic bag when it is rolled up, improving the tension of the plastic bag when it is rolled up, and avoiding the situation that the plastic bag is stacked on the winding roller 130 due to low tension when rolling the plastic bag;
[0043] When it is necessary to cool the newly produced plastic bag, the newly produced plastic bag only needs to be passed through the top of the cooling shaft B202, and then through the middle of the cooling shaft A201 and the cooling shaft B202, and finally the plastic bag is passed upward from the bottom of the cooling shaft A201. At this time, the spring B207 will drive the connecting block A204 to slide inside the side plate 200, and the connecting block A204 will drive the cooling shaft B202 to move toward the cooling shaft A201, so that the plastic bag is clamped, and then the water pump 209 is turned on, and the water pump 209 will pass the connecting pipe 216 to cool the plastic bag. The coolant in the water tank 208 is injected into the water storage plate 210, and the water storage plate 210 will transport the coolant to the cooling shaft A201 and the cooling shaft B202 through the water inlet pipe A211 and the water inlet pipe B212. At this time, the cooling shaft A201 and the cooling shaft B202 will cool the plastic bag. As the coolant continues to flow, the coolant will flow into the cooler 213 through the water outlet pipe A214 and the water outlet pipe B215. After the cooler 213 cools the coolant again, it flows back to the water tank 208 through the connecting pipe 216, thereby completing the cooling of the plastic bag;
[0044] When the plastic bag needs to be cooled again, the fan 301 only needs to be turned on. At this time, the fan 301 will blow the external air to the plastic bag through the air inlet 300, and the filter plate 302 will filter the flowing air, thereby preventing dust or impurities in the air from adhering to the surface of the plastic bag, thereby improving the quality of plastic bag production. When the filter plate 302 needs to be replaced, the lever 307 only needs to be moved, and the lever 307 will drive the block B306 inside the bracket 103. Slide, and when the block B306 is away from the slot 303, the filter plate 302 can be pulled out of the slot 308, and after the new or cleaned filter plate 302 is inserted into the slot 308, the push block is released. At this time, the block B306 will move upward due to the elastic force of the spring B207, and when the block B306 is stuck in the slot 303, the filter plate 302 can be fixed in the slot 308, thereby completing the replacement of the filter plate 302, and at the same time, it also makes it easy to disassemble and clean the filter plate 302.
