Description

Technical Field

[0001] This utility model belongs to the field of blown film machine technology, specifically relating to a blown film machine feeding device for protective film. Background Technology

[0002] A protective film blowing machine feeds dried polyethylene granules and other plastic raw materials into a hopper, where the granules, by their own weight, enter the screw. Upon contact with the screw's beveled edges, the rotating beveled edges exert a thrust on the plastic, propelling the granules forward. During this movement, friction between the plastic and the screw, between the plastic and the barrel, and collisions between the granules, combined with external heating of the barrel, gradually melt the plastic. The molten plastic is filtered through the die head to remove impurities and exits through the die orifice. It is then cooled and inflated by an air ring, passes through a herringbone plate and traction rollers, and is finally wound into a roll by a winding device.

[0003] Since the packaging bags for plastic raw material particles are generally plastic woven bags, manual unpacking and unloading are still required before feeding, which is labor-intensive and affects feeding efficiency. Utility Model Content

[0010] Preferably, the gear meshes with the rack.

[0011] Preferably, the worm gear meshes with the gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This extrusion film feeding device for protective films uses a conveyor mechanism to transport plastic woven bags containing plastic raw material particles into a fixed box. The bags fall under gravity, allowing them to be sliced ​​open by vertical blades, thus replacing manual bag removal. A movable plate is pushed by a spring and the plastic woven bags, resulting in high flexibility and facilitating the complete slicing of the bags. Gear 1 drives a rack to move horizontally, adjusting the horizontal position of the clamping rods. When the worm rotates, the spiral grooves on its surface and the tooth grooves of gear 2 transmit motion and power through sliding contact, causing gear 2 to rotate. This drives the clamping rods closer together, and the symmetrically arranged clamping rods effectively grip the plastic woven bags and pull them to both sides, facilitating the removal of waste plastic woven bags.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides the following technical solution: A feeding device for a blown film machine for protective film, including a conveying mechanism 1, a conveying mechanism 2, and a fixed box 3. A support plate 4 is fixedly connected to the inner side of the fixed box 3. A movable plate 5 is slidably connected to the surface of the support plate 4. Blades 6 are fixedly connected to both the movable plate 5 and the inner wall of the fixed box 3. A fixed plate 7 is fixedly connected to one side of the fixed box 3. A spring 8 is fixedly connected to one side of the fixed plate 7. A support rod 9 is fixedly connected to the side of the fixed box 3. A bottom box 10 is fixedly connected to the inner side of the support rod 9. An mounting plate 11 is fixedly connected to one side of the bottom box 10. The mounting plate 11 is internally fixed... A motor 12 is connected, and a gear 13 is fixedly connected to the output end of the motor 12. A support rod 14 is fixedly connected to the upper surface of the mounting plate 11. A gear 15 is slidably connected to the top end of the support rod 14. A support rod 16 is fixedly connected to the upper surface of the gear 15. A horizontal plate 17 is fixedly connected to the upper surface of the support rod 16. A motor 18 is fixedly mounted on the upper surface of the horizontal plate 17. A worm gear 19 is fixedly connected to the output end of the motor 18. A support shaft 20 is fixedly connected to the upper surface of the horizontal plate 17. A gear 21 is rotatably connected to the surface of the support shaft 20. A clamping rod 22 is fixedly connected to the upper surface of the gear 21.

[0022] In this embodiment, the conveying mechanism 1 facilitates the transport of plastic woven bags containing plastic raw material particles to the fixed box 3. The plastic woven bags containing plastic raw material particles fall under the action of gravity, so that the plastic woven bags can be cut open by the vertical blade 6, thereby replacing manual bag opening. The movable plate 5 can be pushed by the spring 8 and the plastic woven bags containing plastic raw material particles to produce translation. Therefore, the movable plate 5 has high flexibility, which is conducive to fully cutting open the plastic woven bags. The gear 13 can drive the rack 15 to translate, which is conducive to adjusting the horizontal position of the clamping rod 22. When the worm gear 19 rotates, the spiral pattern on its surface and the tooth groove of the gear 21 can transmit motion and power through sliding contact, thereby driving the gear 21 to rotate, which is conducive to driving the clamping rods 22 to move closer to each other. Thus, the symmetrically arranged clamping rods 22 are conducive to clamping the plastic woven bags and pulling them to both sides, which is conducive to removing the plastic woven bag waste.

[0023] Specifically, the support plate 4 is symmetrically arranged, and the movable plate 5 has a groove on its side that matches the support plate 4, so that the movable plate 5 can move stably along the support plate 4, which is both flexible and stable.

[0024] Specifically, one end of the spring 8 is fixedly connected to the movable plate 5, and there are three springs 8. The arrangement of the springs 8 helps to push the movable plate 5 into the fixed box 3, so that the symmetrical blades 6 move closer to each other, which in turn helps to cut open the plastic woven bag completely.

[0025] Specifically, the inner wall of the bottom box 10 is fixedly connected with a baffle 23, and the baffle 23 is arranged in a horizontal array. The baffle 23 helps to intercept the cut plastic woven bag and place it within the clamping range of the clamping bar 22, so that the plastic raw material particles can fall into the bottom box 10.

[0026] Specifically, both conveying mechanism 1 and conveying mechanism 2 are inclined, with the right end of conveying mechanism 1 located above the fixed box 3 and the left end of conveying mechanism 2 located below the bottom box 10. Thus, conveying mechanism 1 facilitates the transport of plastic woven bags containing plastic raw material particles into the fixed box 3, while conveying mechanism 2 facilitates the receiving and transport of plastic raw material particles discharged from the bottom box 10, and can transport the plastic raw material particles into the unloading equipment.

[0027] Specifically, gear 13 meshes with rack 15, and the gear 13 drives the interlaced racks 15 to move in opposite directions, which helps to adjust the spacing between the symmetrical clamps 22.

[0028] Specifically, the worm 19 meshes with the gear 21. The two gears 21 are a group and located on both sides of the worm 19. The worm 19 drives the gears 21 on both sides to move in opposite directions through the worm gear transmission principle, which is conducive to driving the symmetrical clamping rod 22 to open or close.

[0029] The working principle or usage process of this utility model is as follows: In use, the conveyor mechanism 1, conveyor mechanism 2, and base box 10 are first fixedly installed using a fixing frame. The right end of conveyor mechanism 1 should be above the fixing box 3, and the left end of conveyor mechanism 2 should be below the base box 10. When conveyor mechanism 1 operates, it transports the plastic woven bag containing plastic raw material particles into the fixing box 3. The plastic woven bag falls under gravity, allowing it to be sliced ​​open by the vertical blades 6. The plastic raw material particles then fall into the base box 10, thus replacing manual bag opening. The movable plate 5 is pushed by the spring 8 and the plastic woven bag containing plastic raw material particles, resulting in translation. Therefore, the movable plate 5 has high flexibility, which is beneficial for the symmetrical blades 6 to fully slice the plastic woven bag. Then, the motor 12 is started to drive the gear 13, which can move the interlaced... The rack 15 moves horizontally, which helps to adjust the horizontal position of the clamping rod 22. The control motor 18 starts and drives the worm gear 19 to rotate. The spiral pattern on the surface of the worm gear 19 and the tooth groove of the gear 21 can transmit motion and power through sliding contact, thereby driving the gear 21 to rotate. This helps to drive the symmetrical clamping rods 22 to move closer to each other and close, which can clamp the plastic woven bag. Then, the control motor 12 output end drives the gear 13 to rotate in the opposite direction, so that the clamping rods 22 can pull the plastic woven bag out to both sides. After the plastic woven bag is pulled out, the motor 18 drives the worm gear 19 to rotate in the opposite direction, thereby driving the symmetrical clamping rods 22 to open and release the plastic woven bag. The conveying mechanism 2 runs to receive and transport the plastic raw material particles discharged from the bottom box 10. It can transport the plastic raw material particles to the unloading equipment. The electrical equipment in this equipment is all externally powered and controlled by the matching control switch to operate and shut down.
