Description

Technical Field

[0001] This utility model relates to the field of PE film raw material conveying technology, and more specifically, to a PE film raw material conveying device. Background Technology

[0002] Polyethylene, a thermoplastic resin polymerized from ethylene, is characterized by being odorless, non-toxic, smooth to the touch, excellent low-temperature resistance, and good chemical stability, and is widely used in the film manufacturing field. In the production of PE film, the raw materials need to be crushed into granules to facilitate subsequent processing. However, the PE raw material conveying devices commonly used in the present technology often lack an effective grading and filtration mechanism after crushing, resulting in raw materials of different particle sizes directly entering the melting stage. This can easily cause problems such as incomplete melting and uneven raw material density, which not only prolongs the processing time and increases energy consumption, but also directly affects the quality stability of the final film product. For example, the Chinese utility model patent (application number: CN202420449252.1) discloses a "PE film raw material conveying device," the description of which states: "Polyethylene, abbreviated as PE, is a thermoplastic resin obtained by polymerizing ethylene. Polyethylene is odorless, non-toxic, has a waxy feel, excellent low-temperature resistance, good chemical stability, and can withstand the corrosion of most acids and alkalis. Before conveying PE raw materials, they need to be processed by crushing them with a crusher to obtain granular raw materials, which facilitates subsequent processing. However, after crushing the PE raw materials, they are directly used in subsequent processing without filtration. These PE particles are of varying sizes, which often leads to incomplete melting or uneven density of the melted raw materials. This not only prolongs the melting time and wastes fuel, but also affects the yield of PE film produced from the PE raw material particles. Therefore, we propose a PE film raw material conveying device to solve the above problems." Based on this, this utility model provides a PE film raw material conveying device to solve the problems mentioned in the background art.

[0003] To address the aforementioned problems, we have made improvements and proposed a PE film raw material conveying device. Summary of the Invention

[0004] The purpose of this invention is to address the problem that existing PE raw material conveying devices often lack an effective grading and filtration mechanism after crushing, resulting in raw materials of varying particle sizes directly entering the melting process. This can easily lead to incomplete melting and uneven raw material density, which not only prolongs processing time and increases energy consumption but also directly affects the quality stability of the final film product.

[0005] In order to achieve the above-mentioned objectives, this invention provides a PE film raw material conveying device to improve the above-mentioned problems.

[0006] The application is as follows: A PE film raw material conveying device includes a workbench, a movable frame fixedly installed at the bottom of the workbench, and a pad and a second perforated plate spaced apart at the center of the top of the workbench. A through-hole conveyor belt is sleeved on the outside of the pad and the second perforated plate. Filter components that achieve crushing through reciprocating motion are spaced apart below the second perforated plate, and the filter components are located between the through-hole conveyor belts. Limiting components are spaced apart above the through-hole conveyor belts.

[0007] As a preferred technical solution of this application, the filter assembly includes a pin correspondingly disposed below the second perforated plate, and several horizontal shafts are fixedly installed below the pins, and the several horizontal shafts are connected by two sets of spaced vertical shafts.

[0008] As a preferred technical solution of this application, the bottom of the two sets of horizontal shafts located at both ends are symmetrically fixed with movable shafts, and the bottom of the movable shafts is fixedly installed with a second spring, and the bottom of the outer side of the movable shafts is fitted with a second set of shafts.

[0010] As a preferred technical solution of this application, the inner side of the through-hole conveyor belt has symmetrical side plates about the left and right sides of the filter assembly. The top of the two sets of side plates is fixedly connected to the bottom of the pad. There are guide plates symmetrically spaced between the two sets of side plates. The guide plates are inclined inward. The top of the guide plate has an inwardly extending groove. The groove matches the eccentric block. The top of the guide plate is fixedly connected to the drive motor and the bottom of the second set of shafts.

[0011] As a preferred technical solution of this application, a collection box is fixedly installed at the bottom of the two sets of guide plates, the inner cavity of the collection box is connected to the gap between the two sets of guide plates, and side grooves communicating with the inner cavity are opened at the bottom of both sides of the collection box.

[0012] As a preferred technical solution of this application, the collection box is symmetrically equipped with conduits on both sides, the inner side of the conduits is connected to the side groove, and the bottom of the inner side of the conduits is inclined.

[0013] As a preferred technical solution of this application, it also includes a first perforated plate, the top of which has a rectangular array of bending shafts.

[0014] As a preferred technical solution of this application, baffles are symmetrically arranged on both sides of the through-hole conveyor belt, and the bottom of the baffles is fixedly connected to the top of the workbench.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: In this application, by setting a through-hole conveyor belt, a second perforated plate, and a pin-type filter assembly driven by an eccentric block at the top of the workbench, the PE raw material can be dynamically crushed and graded during the conveying process, effectively solving the problems of incomplete melting and uneven density caused by the different particle sizes of raw materials in the prior art. Through the cooperation of the pin and the second perforated plate, unqualified particles are crushed by impact in real time and qualified particles fall smoothly. Combined with the inclined guide plate and collection box structure, qualified raw materials can be quickly collected and guided to the next process, which not only improves the melting efficiency of raw materials and the consistency of product quality, but also reduces energy consumption and secondary processing links. In addition, by setting a bending shaft and a first spring buffer structure, the device can adapt to the conveying and crushing requirements of raw materials of different sizes.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Example 1, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A PE film raw material conveying device includes a workbench 1, a movable frame 2 fixedly installed at the bottom of the workbench 1, and a pad 12 and a second perforated plate 13 spaced apart at the center of the top of the workbench 1. A through-hole conveyor belt 3 is sleeved on the outside of the pad 12 and the second perforated plate 13. Filter components that achieve crushing through reciprocating motion are spaced apart below the second perforated plate 13, and the filter components are located between the through-hole conveyor belts 3. Limiting components are spaced apart above the through-hole conveyor belts 3.

[0023] Furthermore, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the filter assembly includes a pin 21 correspondingly disposed below the second perforated plate 13. Several horizontal shafts 19 are fixedly installed below the pin 21, and the several horizontal shafts 19 are connected by two sets of spaced vertical shafts 20.

[0024] Furthermore, the bottom of the two sets of horizontal shafts 19 located at both ends is symmetrically fixed with movable shafts 22, and the bottom of the movable shafts 22 is fixedly installed with a second spring 23, and the bottom of the outer side of the movable shafts 22 is fitted with a second set of shafts 24.

[0025] Furthermore, an eccentric block 18 is provided at the center of the bottom of the two sets of horizontal shafts 19 located at both ends, and a drive motor 17 is fixedly installed on the outside of the eccentric block 18. In use, the drive motor 17 drives the eccentric block 18 fixedly installed at its output end to rotate, which in turn pushes the horizontal shaft 19 in contact with the eccentric block 18. This, in turn, works with the vertical shaft 20 and the ejector pins 21, which are evenly distributed on its top and correspond to the second perforated plate 13, to move back and forth. This allows the material to pass through the pre-set hole between the second perforated plate 13 and the through-hole conveyor belt 3, and come into contact with the raw material conveyed by the through-hole conveyor belt 3. Smaller raw materials flow directly into the bottom of the second perforated plate 13 through the gap between the ejector pins 21 and the hole in the second perforated plate 13. Unqualified raw materials move upward under the impact of the ejector pins 21 and combine with the bottom of the first perforated plate 8. At this time, the ejector pins 21 can crush larger particles of raw material, allowing them to pass through the through-hole conveyor belt 3 and the second perforated plate 13.

[0026] Furthermore, such as Figure 3 , Figure 4 and Figure 5 As shown, the inner side of the through-hole conveyor belt 3 has symmetrical side plates 14 about the filter assembly. The top of the two sets of side plates 14 is fixedly connected to the bottom of the pad plate 12. There are guide plates 15 symmetrically spaced between the two sets of side plates 14. The guide plates 15 are inclined inward. The top of the guide plate 15 has an inwardly extending groove 16. The groove 16 matches the eccentric block 18. The top of the guide plate 15 is fixedly connected to the drive motor 17 and the bottom of the second set of shafts 24.

[0027] Furthermore, a collection box 25 is fixedly installed at the bottom of the two sets of guide plates 15. The inner cavity of the collection box 25 is connected to the gap between the two sets of guide plates 15. Side grooves 26 that are connected to the inner cavity are opened at the bottom of both sides of the collection box 25.

[0028] Furthermore, symmetrical conduits 27 are installed on both sides of the collection box 25. The inner side of the conduit 27 is connected to the side groove 26, and the bottom of the inner side of the conduit 27 is inclined. When in use, when the raw material falls between the two sets of side plates 14, it will be guided to the inside of the collection box 25 by the symmetrically distributed guide plates 15, and the qualified raw material will be discharged through the side groove 26 and the conduit 27 and then transported to the next process.

[0029] Furthermore, it also includes a first perforated plate 8, the top of which has a rectangular array of bending shafts 9. The bending shafts 9 are sleeved on the outside of the baffle 7. One end of the bending shafts 9 is fixedly connected to the top of the worktable 1, and the other end of the bending shafts 9 is fixedly installed with a first spring 11. A first set of shafts 10 is sleeved on the outside of the first spring 11, and the first set of shafts 10 is sleeved with the bending shafts 9. The first perforated plate 8 is installed through the bending shafts 9, which facilitates the compression of raw materials of different sizes during conveying, and can also be used in conjunction with the ejector pin 21 to crush the raw materials.

[0030] Furthermore, such as Figure 3 and Figure 7 As shown, baffles 7 are symmetrically arranged on both sides of the through-hole conveyor belt 3, and the bottom of the baffles 7 is fixedly connected to the top of the workbench 1. The baffles 7 facilitate the limiting and guiding of raw materials during transportation by the through-hole conveyor belt 3.

[0031] Furthermore, rotating rollers 6 are symmetrically arranged on the inner side of the through-hole conveyor belt 3, and a drive motor 4 is spaced below one end of a set of rotating rollers 6, and the output end of the drive motor 4 meshes with one end of a set of rotating rollers 6 through a synchronous belt 5. In use, the transmission motor 4 and the synchronous belt 5 engaged with the output end drive a set of rotating rollers 6 to rotate, which in turn drives the through-hole conveyor belt 3 to rotate in a cycle, thereby conveying raw materials.
