Description

Technical Field

[0001] The utility model relates to the technical field of PE heat shrink film production, and more specifically to a feeding device for PE heat shrink film production. Background Art

[0002] PE heat shrink film is a surface protective film that packages items through the principle of heat shrinkage. It mainly uses low-density polyethylene (LDPE) containing a large number of long-chain branched structures as its raw material. This material has a high shrinkage rate and strength.

[0003] The patent with the publication number CN221456737U discloses a feeding device for the production of PE heat shrinkable film, wherein the hollow inside of the shell is provided with an extrusion cavity for feeding, and a nozzle for extruding raw materials is provided on one side of the extrusion cavity, and a feed port connected to the extrusion cavity is provided at the upper end of the shell, and a piston for conveying raw materials is provided on the sliding sleeve in the extrusion cavity, and an adjustment mechanism is connected between one side of the piston and the inner wall of the extrusion cavity. Beneficial effect: By providing a closed shell, the raw materials can be prevented from overflowing due to excessive accumulation, and when the piston contacts the nozzle, the slider is located on the side of the feed port away from the nozzle, which can prevent the slider from contacting the raw materials when the piston extrude the raw materials, thereby preventing the sliding gap of the slider from being reduced due to the filling of the raw materials, further ensuring the stability of the sliding of the slider, and improving the practicality of the feeding device.

[0004] Although the device has many beneficial effects, the following problems still exist: although the feeding device ensures the stability of the sliding of the slider and improves the practicality of the feeding device, the PE raw material will be fed continuously during the feeding process. If the feeding is not timely, blockage is likely to occur, and the feeding flow rate will slow down, reducing the feeding efficiency. Utility Model Content

Two symmetrically distributed rectangular grooves are formed in the inner wall of the feeding pipe. The two sliding blocks are slidably connected with the corresponding rectangular grooves. The pushing column and the connecting block are slidably attached to the inner wall of the feeding pipe.

[0011] Preferably, a transfer box is fixedly connected to the outer surface of the storage bin. Two gears are rotatably connected to the outer surface of the storage bin.

Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0026] A feeding device for PE heat shrinkable film production includes a connecting frame 1. A storage tank 2 is fixedly installed at the top of the connecting frame 1. A feeding pipe 4 is fixedly connected inside the connecting frame 1. A pushing column 3 is arranged inside the feeding pipe 4. The bottom of the storage tank 2 is connected through the feeding pipe 4. It further includes:

[0027] A feeding and pushing assembly, which is located on the outer surface of the connecting frame 1 and is used to push the pushing column 3 to push out the raw materials for PE heat shrinkable film production in the feeding pipe 4;

[0028] The mixing component is located inside the storage bin 2 and is used to fully mix the heat-shrinkable film raw materials in the storage bin 2. As the pushing column 3 moves forward, it gradually pushes the raw materials at the connection between the bottom of the storage bin 2 and the feeding pipe 4 into the feeding pipe 4. The raw materials are continuously pushed forward by the pushing column 3 in the feeding pipe 4 until they are output from the other end of the feeding pipe 4 to complete the feeding.

[0029] Furthermore, the feeding and pushing component includes a threaded rod 5 and a first motor 6. The threaded rod 5 is rotatably connected inside the connecting frame 1. The threaded rod 5 is threadedly sleeved with the pushing column 3. The outer surface of the connecting frame 1 is fixedly installed with a first motor 6. The output end of the first motor 6 is fixedly connected to the end of the threaded rod 5. The output end of the first motor 6 drives the threaded rod 5 to rotate inside the connecting frame 1. Since the threaded rod 5 is threadedly sleeved with the pushing column 3, when the threaded rod 5 rotates, the pushing column 3 will move along the direction of the feeding pipe 4 under the drive of the thread.

[0030] Furthermore, the end of the pushing column 3 is fixedly connected with a connecting block 12. Two symmetrically distributed sliding blocks 13 are fixedly connected to the outer surface of the connecting block 12. Two symmetrically distributed rectangular grooves 14 are opened on the inner wall of the feeding pipe 4. The two sliding blocks 13 are slidably connected with the corresponding rectangular grooves 14. The pushing column 3 and the connecting block 12 are slidably attached to the inner wall of the feeding pipe 4. The connecting block 12 and the sliding blocks 13 at the end of the pushing column 3 are restricted by the sliding in the rectangular grooves 14, ensuring the stable movement of the pushing column 3 and preventing it from rotating. As the pushing column 3 moves forward.

[0031] Furthermore, the outer surface of the storage bin 2 is fixedly connected with an adapter box 15. Two gears 9 are rotatably connected to the outer surface of the storage bin 2. The two gears 9 are meshed and both are located inside the adapter box 15. The outer surface of the adapter box 15 is fixedly installed with a second motor 8. The output end of the second motor 8 is fixedly connected with the adjacent gear 9. The output end of the second motor 8 drives the gear 9 connected to it to start rotating. Since the two gears 9 are meshed and both are located inside the adapter box 15, when one gear 9 rotates, it will drive the other gear 9 to rotate in the opposite direction. These two gears 9 are respectively fixedly connected with two rotating shafts 10. Therefore, their rotation will drive the rotating shafts 10 to rotate inside the storage bin 2.

[0032] Furthermore, the mixing component includes a rotating shaft 10 and stirring blades 11. Two symmetrically distributed rotating shafts 10 are rotatably connected inside the storage bin 2. A plurality of equally spaced stirring blades 11 are fixedly connected to the outer surfaces of the two rotating shafts 10. The two gears 9 are fixedly connected with the corresponding rotating shafts 10. As the rotating shafts 10 rotate, the stirring blades 11 will fully stir and mix the raw materials in the storage bin 2 to ensure the uniformity and consistency of the raw materials.

[0033] Further, a feed inlet 7 is fixedly connected to the top of the storage bin 2, and the PE heat shrinkable film raw material is added into the storage bin 2 through the feed inlet 7.

[0034] Working principle: When the staff needs to use the feeding device for PE heat shrinkable film production, when the PE heat shrinkable film raw material is added into the storage bin 2 through the feed inlet 7, the raw material will naturally fall into the storage bin 2 and enter the conveying pipe 4. Subsequently, the second motor 8 is started, and the output end of the second motor 8 drives the gear 9 connected thereto to start rotating. Since the two gears 9 are meshed and both are located inside the transfer box 15, when one gear 9 rotates, it will drive the other gear 9 to rotate in the opposite direction. These two gears 9 are respectively fixedly connected to the two rotating shafts 10, so their rotation will drive the rotating shafts 10 to rotate inside the storage bin 2. A plurality of equally spaced stirring blades 11 are installed on the outer surface of the rotating shaft 10. As the rotating shaft 10 rotates, the stirring blades 11 will fully stir and mix the raw material in the storage bin 2 to ensure the uniformity and consistency of the raw material. After the raw material is mixed evenly, the first motor 6 is started, and the output end of the first motor 6 drives the threaded rod 5 to rotate inside the connecting frame 1. Since the threaded rod 5 is threadedly sleeved with the pushing column 3, when the threaded rod 5 rotates, the pushing column 3 will move along the direction of the conveying pipe 4 under the drive of the thread. At the same time, the connecting block 12 and the sliding block 13 at the end of the pushing column 3 are restricted by the sliding in the rectangular groove 14, ensuring the stable movement of the pushing column 3 and preventing it from rotating. As the pushing column 3 moves forward, it will gradually push the raw material at the connection between the bottom of the storage bin 2 and the conveying pipe 4 into the conveying pipe 4. The raw material in the conveying pipe 4 is continuously pushed forward by the pushing column 3 until it is output from the other end of the conveying pipe 4 to complete the feeding. The pushing column 3 blocks the raw material in the storage bin 2 from entering the conveying pipe 4 during the forward movement, which can achieve intermittent feeding, thus avoiding the blockage problem caused by the continuous entry of raw material during the feeding process. The first motor 6 is started again to reverse it, so that the connecting block 12 moves close to the first motor 6 and the raw material enters the conveying pipe 4 again.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
