Description

Technical Field

[0001] The invention relates to the technical field of carrier belt recycling, in particular to a waste material recycling device for a high-speed carrier belt particle forming machine. Background Art

[0002] Most of the existing carriers are made of plastic. The carrier particle molding machine refers to a special equipment used to produce carriers. In the carrier particle molding machine, the raw materials are heated and plasticized, molded, cooled and solidified, and cut to complete the production of the carrier. In the production process, most of the waste is generated by the carrier scraps remaining during cutting, products of unqualified size, etc.

[0003] After the waste materials in the carrier particle forming machine are collected, the carrier tape needs to be crushed, hot-melted, plasticized and granulated. During this process, the waste materials are reprocessed into raw materials in the carrier particle forming machine to achieve the reuse of the waste materials.

[0004] For example, the patent with announcement number CN220428958U and publication date of February 2, 2024 discloses a plastic crushing device for BOPP film production, which relates to the technical field of BOPP film production equipment, and includes: a crushing mechanism, the crushing mechanism includes a crushing chamber, a crushing roller is installed in the crushing chamber through a bearing, a crushing motor is fixed to the outside of the crushing chamber, and the output shaft of the crushing motor is fixed to the rotating shaft of the crushing roller; an inner feed hopper is fixed on the top of the crushing chamber facing the crushing roller, and a drop hopper is installed on the bottom of the crushing chamber facing the crushing roller; supporting feet are fixed on both sides of the crushing chamber; a rotating filter mechanism, the rotating filter mechanism includes: a cylinder seat, an outer feed hopper is provided on the top of the cylinder seat; an extension is provided on the inner side of the outer feed hopper; a discharge channel is provided at the bottom of the cylinder seat; a discharge conveyor belt is provided in the discharge channel; the cylinder A through groove is provided in the middle of the seat; an intermediate cylinder is provided with a filter hole on the intermediate cylinder; an intermediate material trough is axially provided on the intermediate cylinder; a plurality of scrapers are fixed at intervals on the inner side of the intermediate cylinder; ring plates are fixed at both ends of the intermediate cylinder; a ring seat is fixed on the outside of the ring plate; the intermediate cylinder is arranged on the inner side of the through groove, and the ring seat is installed at both ends of the through groove through guide bearings; the extension part is movably fitted on the outer wall of the intermediate cylinder; the inner cylinder is arranged on the inner side of the intermediate cylinder, and the scraper is movably fitted on the outer wall of the inner cylinder; a feed port and a drop port are respectively provided on the top and bottom of the inner cylinder; a rotating drive mechanism, the rotating drive mechanism includes a belt disk fixed to the outside of one of the ring seats, and the belt disk is connected to the screening motor through a transmission belt; the crushing chamber is arranged on the inner side of the inner cylinder, and the inner cylinder is fixed to the outer wall of the crushing chamber by a fixing member; the feed port is opposite to the inner feed hopper, and the drop hopper is opposite to the drop port.

[0005] In the prior art, the scraper is located between the middle cylinder and the inner cylinder. The middle cylinder drives the scraper to rotate synchronously. One end of the scraper is connected to the middle cylinder, and the other end is in contact with the inner cylinder. When the middle cylinder drives the scraper to rotate, friction is generated between the scraper and the outer wall of the inner cylinder. Long-term friction will cause a gap between the scraper and the inner cylinder. Since the existing plastic carrier is long and includes types such as PS carrier, PC carrier, ABS carrier, etc., the thickness of the commonly used carrier is between 0.22mm and 0.50mm. In other words, some carrier waste is in the The thickness of the crushed plastic sheets is also between 0.22mm and 0.50mm. When the plastic sheets of this thickness are sent into the crushing box by the scraper for secondary crushing to reduce the volume of the plastic sheets, the plastic sheets will enter the gap between the scraper and the inner cylinder during the feeding process, causing the scraper to be stuck on the inner cylinder. Although a telescopic scraper can be used to solve the problems of wear gap and jamming, when the scraper moves to the feed port, the telescopic scraper loses the obstruction of the inner cylinder and causes the scraper to stretch instantly and may not be able to reset.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms “connected” and “connected” should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] like Figure 1-9 As shown, an embodiment of the present invention provides a shell 1, a feed port 11 is provided on the top of the shell 1, a crushing mechanism 4 is opened inside the shell 1, a filter feed cavity is formed around the crushing mechanism 4 in the shell 1, the filter screen plate 2 is located in the bottom area of the filter feed cavity, a scraper 3 is installed between the crushing mechanism 4 and the filter screen plate 2, and the scraper 3 is driven to revolve and passively swing in the filter feed cavity, wherein the revolution of the scraper 3 can send the solid particles on the filter screen plate 2 to the feed port 11, and the passive swing of the scraper 3 can drive it to always adhere to the inner wall of the filter feed cavity.

[0033] Specifically, the waste generated during the use of the carrier particle forming machine is fed into the shell 1 from the feed port 11, and the crushing mechanism 4 is located directly below the feed port 11. The waste enters the crushing mechanism 4 through the feed port 11 and is crushed in the crushing mechanism 4. In this embodiment, the crushing mechanism 4 preferably includes at least a crushing box, a crushing knife, and a rotary drive component that drives the crushing knife to rotate. The rotary drive component can be a motor, a rotary cylinder, etc. The crushing box is installed directly below the feed port 11, and the crushing knife and the rotary drive are located in the crushing box. The crushing knife is driven by the rotary drive component to rotate in the crushing box to crush the waste. This is an existing The technology is no longer described in detail. The filter feeding cavity is formed between the crushing box and the inner wall of the shell 1. The filter screen plate 2 is installed at the bottom of the filter feeding cavity and is fixedly connected to the shell 1. After filtering by the filter screen plate 2, qualified products enter the subsequent processing equipment. After hot melting, plasticization and granulation, the raw materials of the carrier particle forming machine are obtained and can be sent to the carrier particle forming machine again for use; unqualified products, that is, particles with larger particle sizes, will remain on the filter screen plate 2. Because the shell 1 is also equipped with a driving mechanism 5, the driving mechanism 5 drives the scraper 3 to revolve in the shell 1. One end of the scraper 3 is in contact with the filter screen plate 2, and the other end is connected to the driving mechanism 5.

[0034] In this embodiment, preferably, the driving mechanism 5 includes a ring 51, which is driven to rotate in the shell 1, and the end of the scraper 3 facing away from the filter screen plate 2 is connected to the ring 51. The ring 51 is embedded in the inner wall of the shell 1 and is rotatably connected to the shell 1. When the ring 51 rotates, it drives the scraper 3 to revolve in the shell 1. During the revolution of the scraper 3, one end of the scraper 3 slides along the surface of the filter screen plate 2, thereby pushing the plastic particles on the filter screen plate 2 to move thereon. Specifically, the driving mechanism 5 also includes a driving motor 52 and a first gear 53. The driving motor 52 is fixedly mounted on the outer wall of the shell 1. The transmission shaft at the output end of the driving motor 52 passes through the shell and is connected to the first gear 53. The first gear 53 is rotated. It is installed on the inner wall of the shell 1, and a tooth groove 54 is installed on the inner wall of the ring 51. The first gear 53 is engaged with the tooth groove 54. The ring 51 constitutes an internal gear ring structure. An annular groove 12 is provided inside the shell 1. The ring 51 is rotatably installed in the annular groove 12. A connecting shaft 31 is installed on both sides of the scraper 3. One end of the connecting shaft 31 is fixed to the scraper 3, and the other end passes through and is rotatably connected to the ring 51. The scraper 3 is rotatably connected to the ring 51 through the connecting shaft 31. The torsion spring 55 is installed at the rotating connection between the connecting shaft 31 and the ring 51. During actual use, the drive motor 52 drives the first gear 53 to rotate inside the shell 1, and the engagement of the first gear 53 drives the ring 51 to rotate inside the shell 1, that is, the ring 51 rotates in the annular groove 12.

[0035] Furthermore, one end of the scraper 3 is rotatably connected to the ring 51, and a torsion spring 55 is installed at the rotation connection. One end of the torsion spring 55 is connected to the ring 51, and the other end is connected to the scraper 3. The inner wall of the housing 1 is provided with a guide slope 13, which cooperates with the scraper 3 to drive the other end of the scraper 3 to swing downward. Specifically, Figure 2-Figure 4 As shown, the guide slope 13 is arc-shaped, and the center of the guide slope 13 is located below the center of the ring 51, so the radial distance between the guide slope 13 and the ring 51 becomes shorter and shorter from bottom to top. There are two groups of guide slopes 13, which are symmetrically arranged along the filter screen 2. The scraper 3 is initially located on the filter screen 2. The end of the scraper 3 that is rotatably connected to the ring 51 is the first end, and the end that contacts the filter screen 2 is the second end. In the initial state, the first end is located on the side of the rotation direction of the second end, so the scraper 3 is initially arranged in an inclined manner. At this time, the torsion spring 55 is in a contracted state. It should be supplemented that when the torsion spring 55 is in a natural state, the scraper 3 is arranged radially along the ring 51 to Figure 2For example, the first end is located on the left side of the second end, and the ring 51 drives the scraper 3 to rotate to the left, that is, the ring 51 rotates clockwise. During the revolution of the scraper 3, the second end of the scraper 3 moves from the filter plate 2 to the guide slope 13, that is, the plastic particles on the filter plate 2 are pushed onto the guide slope 13. At this time, an angle is formed between the scraper 3 and the guide slope 13, and the plastic particles to be crushed for the second time are located within the angle. Secondly, during the revolution of the scraper 3, the second end of the scraper 3 slides from bottom to top along the guide slope 13. The radial distance from the ring 51 is getting shorter and shorter, so the guide slope 13 will force the scraper 3 to swing downward when the scraper 3 revolves. The torsion spring 55 continues to contract as the scraper 3 rotates, so that the second end contacts the guide slope 13 in real time and gradually moves to the side away from the rotation direction of the scraper 3. As a result, the scraper 3 is always in a downward tilted state during the revolution, and the angle between the scraper 3 and the guide slope 13 is kept within 90 degrees, so that the plastic particles will not slide off the scraper 3 during the revolution.

[0036] The shell 1 is also provided with a feeding trough 14, which is located at the top of the filter feed chamber. When the scraper 3 revolves at a certain angle, the ring 51 drives the scraper 3 to move into the feeding trough 14 in the shell 1. At this time, when the second end of the scraper 3 disengages from the guide slope 13, the scraper 3 is in an approximately horizontal state, and all the plastic particles are located on the scraper 3. The torsion spring 55 drives the scraper 3 to reset and rotate on the ring 51, that is, the scraper 3 rotates in the feeding trough 14, and the feeding trough 14 is connected to the feed port 11. The rotation of the scraper 3 feeds the plastic particles thereon into the feed port 11, and then the ring 51 resets and rotates, that is, rotates counterclockwise, driving the scraper 3 to rotate synchronously. At this time, the scraper 3 has been reset to the initial radial arrangement under the action of the torsion spring 55, and then when the scraper 3 contacts the guide slope 13 again, it is on the guide slope 13. The scraper 3 is forced to swing during the revolution under the resistance of the end, that is, the scraper 3 rotates upward. At this time, the torsion spring 55 begins to expand. Under the obstruction of the guide inclined surface 13, the moving speed of the second end of the scraper 3 is less than the moving speed of the first end. That is to say, when the scraper 3 is reset and rotated onto the filter screen plate 2, the second end of the scraper 3 is located to the right of the first end. If the scraper 3 is in the first state when the ring 51 rotates clockwise and is in the second state when it rotates counterclockwise, then the first state and the second state are arranged as mirror images of each other. The first state and the second state are respectively adapted to the scraper 3 to send the plastic particles on the filter screen plate 2 in different rotation directions, and after the ring 51 rotates clockwise and then rotates counterclockwise, the scraper 3 can also be passively adjusted from the first state to the second state under the cooperation of the guide inclined surface 13, and vice versa.

[0037] Finally, in this embodiment, the use of the torsion spring 55 allows the second end of the scraper 3 to always fit on the guide bevel 13. Although the sliding of the second end on the guide bevel 13 may cause wear, the torsion spring 55 uses its own elastic force to avoid the formation of a gap between the scraper 3 and the guide bevel 13 when wear occurs, and can also reduce the probability of plastic particles entering the gap between the scraper 3 and the guide bevel 13.

[0038] In another embodiment of the present invention, a switch board 7 is further installed between the feeding chute 14 and the feeding port 11 , and the switch board 7 is used to control the connectivity between the feeding chute 14 and the feeding port 11 .

[0039] Specifically, the upper end of the switch plate 7 is rotatably connected to the inner wall of the shell 1, and the lower end is placed on the vertical plate 8. The vertical plate 8 is fixedly connected to the upper end opening of the crushing box. Side openings are provided on both sides of the feed port 11. The switch plate 7 is located in the side openings. In this embodiment, the switch plate 7 can be driven to rotate in the shell 1 by a driving component such as a motor and a rotary cylinder. When the scraper 3 moves to the inside of the feeding trough 14, the first end of the scraper 3 contacts the upper end of the vertical plate 8, and then the switch plate 7 rotates to open the side opening. After the scraper 3 is tilted, the plastic particles are fed into the feed port 11 from the side opening.

[0040] Due to the setting of the torsion spring 55, when the scraper 3 disengages from the guide slope 13, the torsion spring 55 will reset instantly and drive the scraper 3 to swing quickly to instantly send the material on it into the crushing box. This instant reset action will not only affect whether the plastic particles can completely enter the crushing box, but will also cause an instantaneous increase in the feed amount of the crushing box, resulting in an increase in the feed amount in the crushing box, affecting the crushing effect of the plastic particles. Therefore, in this embodiment, a transmission mechanism 6 is also provided. When the scraper 3 moves to the inside of the feeding trough 14, the scraper 3 is connected to the switch plate 7 through the transmission mechanism 6, and the scraper 3 rotates synchronously with the switch plate 7.

[0041] Specifically, such as Figure 9As shown, the interior of the housing 1 is further provided with a mounting groove 15, which is connected to the filter feed cavity through the annular groove 12, and the mounting groove 15 corresponds to the feeding trough 13. The transmission mechanism 6 includes a driving gear 61 and a driven gear 62, which are located in the mounting groove 15. The driving gear 61 and the driven gear 62 are meshed with the driven gear 62, and both are rotatably connected to the inner wall of the housing 1. A shift lever 64 is installed on the driving gear 61, and the shift lever 64 has an L-shaped structure. The vertical section of the shift lever 64 is located in the mounting groove 15. A slide groove 16 is also provided in the housing 1, and the horizontal section of the shift lever 64 extends out of the mounting groove 15 through the slide groove 16 and fits on the side of the switch plate 7 away from the feed port 11. The slide groove 16 has an arc-shaped structure, and The curvature of the chute 16 is consistent with the curvature of the revolution of the shift lever 64 around the center of the circle of the driving gear 61. The chute 16 connects the feeding trough 13 and the mounting groove 15, so that the shift lever 64 can extend from the mounting groove 15 into the feeding trough 13. A portion of the driven gear 62 is located in the mounting groove 15, and the other portion is located at the connection between the annular groove 12 and the mounting groove 15. One end of the connecting shaft 31 passes through the ring 51 and extends into the annular groove 12, and the end extending into the annular groove 15 is fixedly mounted with the second gear 32. The second gear 32 is located inside the annular groove 12 and cooperates with the driven gear 62. A switch motor 63 is also installed on the outer wall of the housing 1. The output shaft of the switch motor 63 passes through the housing 1 and is connected to the driving gear 61.

[0042] During actual use, when the scraper 3 moves to the inside of the feeding trough 14 and the second end of the scraper 3 disengages from the guide inclined surface 13, the revolution of the ring 51 drives the coupling shaft 31 to move to the connection point between the annular groove 12 and the mounting groove 15, and the second gear 32 moves synchronously with the coupling shaft 31 and meshes with the part of the driven gear 62 extending into the annular groove 12 at the connection point. Since the driving gear 61 is connected to the switch motor 63, and the driven gear 62 is meshed with the driving gear 61, although the scraper 3 is disengaged from the interference of the guide inclined surface 13, the torsion spring 55 will not reset under the limit of the driving gear 61 and the driven gear 62. When the switch motor 63 drives the driving gear 61 to rotate, the rotation of the driving gear 61 drives the lever 64 to swing, and the lever 64 moves to the side close to the switch plate 7. Under the movement and push of the lever 64 The switch plate 7 is driven to rotate, and the rotation of the switch plate 7 opens the side opening. At the same time, the driving gear 61 is engaged to drive the driven gear 62 to rotate, and the driven gear 62 is engaged to drive the second gear 32 to rotate. The second gear 32 drives the scraper 3 to rotate on the ring 51 through the connecting shaft 31. This rotation causes the scraper 3 to gradually rotate from a horizontal state to an inclined state, and the torsion spring 55 gradually begins to reset. That is to say, as the switch plate 7 slowly opens, the scraper 3 also gradually tilts, and the plastic particles thereon are put into the crushing box from the side opening. That is to say, under the control of the switch motor 63, not only the rotation of the switch plate, i.e., the opening of the side opening is achieved, but also the active driving force of the switch motor 63 is used to drive the passive reset of the torsion spring 55, thereby avoiding the problem of excessive plastic particles being instantly put in due to the instantaneous reset of the torsion spring 55.

[0043] Finally, when the scraper 3 is reset to the radial arrangement and the plastic particles have completely entered the crushing box, the ring 51 directly drives the scraper 3 to rotate in the opposite direction, and the second gear 32 is disengaged from the driven gear 62. Then the switch motor 63 drives the driving gear 61 to reset and rotate, and drives the lever 64 to reset and swing. Under the influence of gravity, the switch plate 7 is placed on the vertical plate 8 again, and the side opening is closed.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
