Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module production technology, specifically relating to a waste filament removal mechanism. Background Technology

[0002] With the rapid development of the photovoltaic industry, more and more photovoltaic products are entering the market. In order to improve power generation efficiency, photovoltaic products made with various processes have been launched on the market: solar cells.

[0003] Currently, one process involves laser-cutting a large-area conductive layer (which can be a metal foil, such as copper foil) to create the conductive pattern to be retained and the waste wires to be removed (the waste product). After the waste wires are removed, the conductive pattern is bonded to a backing plate using EVA film to produce a metal backing plate. Because the conductive layer is thin, it needs to be adsorbed and fixed onto a carrier plate before laser cutting and subsequent processing to facilitate better processing and movement between steps. More specifically, only the conductive pattern area is adsorbed onto the carrier plate; the waste wires are not.

[0004] The substrate has a cutting groove along the laser cutting path on one side where the conductive layer is adsorbed. During cutting, the laser acts within the cutting groove. Because the laser cutting path of the conductive layer is relatively dense, the waste wires generated after cutting are quite thin and easily embedded in the cutting groove. Currently, the waste wires are mainly removed manually by picking them out directly. This method can ensure the yield of the conductive pattern after waste removal, but manual waste removal is very time-consuming and will affect production efficiency. Utility Model Content

[0005] In view of the above-mentioned defects or improvement needs of the existing technology, this utility model provides a waste filament removal mechanism. Its purpose is to ensure the yield of conductive patterns after waste removal by having the air blowing module and the roller clamping module follow each other in operation, while also saving a lot of waste removal time and improving production efficiency.

[0006] To achieve the above objectives, this utility model provides a waste filament removal mechanism, wherein the waste filament removal mechanism is located below the waste product to be removed, and the waste product to be removed faces the waste filament removal mechanism.

[0007] The waste filament removal mechanism includes an air blowing module, a roller clamp module, and a drive module;

[0008] The air blowing module and the roller clamp module are arranged sequentially along the first direction. The air blowing module has a plurality of air blowing holes arranged at intervals. The plurality of air blowing holes are used to blow air onto the waste yarn in the second direction upward.

[0009] The roller clamp module includes a support, a first drive member, and at least one set of roller clamps. Each set of roller clamps includes two active rollers spaced apart along a first direction. The first drive member is located on the support. The axial direction of each active roller extends along a third direction and is rotatably arranged on the support. A gap for clamping and pulling waste wire is formed between the two active rollers in each set of roller clamps. The first drive member drives the two active rollers in each set of roller clamps to rotate in opposite directions.

[0010] The drive module is used to drive the air blowing module and the support to move along a first direction, wherein the first direction and the third direction are two perpendicular directions in the horizontal plane, and the second direction is a vertical direction.

[0011] Optionally, the waste filament removal mechanism further includes an air-blowing drive module, which drives the air-blowing module to reciprocate along a third direction, and the air-blowing drive module is connected to the output end of the drive module.

[0012] Optionally, the air blowing drive module includes a base, a second drive component, and a slide rail. The base is driven to the output end of the drive module. The second drive component and the slide rail are both located on the base. The output end of the second drive component is driven to the air blowing module through a connecting block. The connecting block is slidably engaged with the slide rail, and the slide rail extends in a third direction.

[0013] Optionally, the air blowing drive module further includes a heightening block, the air blowing module is arranged on the heightening block, the heightening block has a strip hole arranged along a second direction, the connecting block has a plurality of connecting holes arranged sequentially along the second direction, and a connecting bolt for locking the heightening block and the connecting block is inserted into the strip hole and one of the connecting holes.

[0014] Optionally, the waste filament removal mechanism further includes an outer cover, which is mounted on the air blowing module. The outer cover covers the air blowing module and the air blowing drive module. The side of the outer cover facing the waste filament has multiple air vents, and the multiple air vents are arranged opposite to the multiple air blowing holes.

[0015] Optionally, the air blowing module includes an air plate and an air pipe connector disposed on the air plate. The air plate has an air cavity, and each air blowing hole is disposed on the side of the air plate facing the waste filament. The air cavity, each air blowing hole, and the air pipe connector are all connected.

[0016] Optionally, the first driving element includes a driving unit and at least two gears. Each of the driving rollers has a gear fitted at one end, and adjacent gears mesh. The driving unit is located on the support, and the power output end of the driving unit is connected to the other end of one of the driving rollers.

[0017] Optionally, each set of roller clamps also includes two driven rollers. The two driven rollers and the two driving rollers in each set of roller clamps correspond one-to-one. Each driving roller and the corresponding driven roller are arranged parallel to each other along the second direction and are driven by a flat belt.

[0018] Optionally, each set of roller clamps further includes floating blocks and adjusting blocks disposed at both ends of the roller clamp module along a third direction. Each floating block is slidably inserted into the support along a first direction. Both ends of one of the active rollers in each set of roller clamps are rotatably inserted into the corresponding floating block. The adjusting block is mounted on the support and has a set screw inserted into it. One end of the set screw abuts against the corresponding floating block to drive the floating block to move.

[0019] Optionally, an elastic element is sandwiched between the set screw and the corresponding floating block.

[0020] Optionally, a baffle is provided at the top edge of the support, and the baffle is located on the side of the support opposite to the direction of movement of the support, and the baffle is parallel to the drive roller.

[0021] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0022] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0023] In the waste filament removal mechanism provided in this embodiment of the invention, after laser cutting, a carrier plate carrying the product to be removed is conveyed to the waste removal station. The carrier plate is then flipped so that the product is facing down (i.e., the side of the carrier plate with the cutting grooves is facing down). Next, the drive module drives the air blowing module and the roller clamp module to move along a first direction, and the air blowing module and the roller clamp module move sequentially below the product to be removed. Finally, for the air blowing module, as it passes under the product to be removed, the air blown through the air blowing holes sweeps away the cutting grooves (i.e., compressed gas is blown upwards through the air blowing holes), causing the waste filaments to fall and detach from the cutting grooves. For the roller clamp module, as it passes under the product to be removed, the waste filaments fall into the gap between the two active rollers in each set of roller clamps. The two active rollers in each set of roller clamps cooperate to clamp and pull the waste filaments, causing them to completely detach from the cutting grooves. The cooperation between the air blowing module and the roller clamp module can improve the yield of conductive patterns while shortening the waste removal time and increasing the waste removal efficiency.

[0024] In other words, the waste filament removal mechanism provided in this embodiment of the utility model, through the sequential operation of the air blowing module and the roller clamping module, not only ensures the yield of conductive patterns after waste removal, but also saves a lot of waste removal time and improves production efficiency.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] The waste filament removal mechanism of this application is located below the waste product to be removed, and the waste product faces the waste filament removal mechanism. Specifically, after the conductive pattern area of ​​the conductive layer is adsorbed and fixed on the carrier plate, the laser cuts the conductive layer along the laser cutting path to obtain the waste product to be removed. The waste product includes the conductive pattern to be retained and the waste filament to be removed. The carrier carries the waste product to be removed and conveys it to the top of the waste filament removal mechanism. The carrier is flipped by the flipping mechanism so that the waste product is facing down (i.e., the waste product is facing the waste filament removal mechanism). During this process, the conductive pattern is always adsorbed and fixed on the carrier plate, while the waste filament is not adsorbed and fixed on the carrier plate. Then, the waste filament on the carrier plate is removed by the waste filament removal mechanism.

[0039] Example:

[0040] Figure 1 This is a schematic diagram of the structure of a waste filament removal mechanism provided in an embodiment of this utility model, as shown below. Figure 1 As shown, the waste filament removal mechanism includes an air blowing module 1, a roller clamp module 2, and a drive module 3. The air blowing module 1 and the roller clamp module 2 are arranged sequentially along a first direction (e.g., the X-axis direction).

[0041] Figure 2 This is a schematic diagram of the air blowing module provided in an embodiment of the present invention. Figure 3 This is an exploded view of the air blowing module provided in an embodiment of this utility model, as shown below. Figure 2 and Figure 3 As shown, the air blowing module 1 has a plurality of air blowing holes 11 arranged at intervals. The plurality of air blowing holes 11 are used to blow air upward along the second direction (e.g., the Z-axis direction) onto the waste wire (i.e., the cutting groove of the carrier plate).

[0042] Figure 4 This is a structural schematic diagram of the roller clamp module provided in this embodiment of the utility model. Figure 5 This is an exploded view of the roller clamp module provided in an embodiment of this utility model, as shown below. Figure 4 and Figure 5 As shown, the roller clamp module 2 includes a support 21, a first drive member 22, and at least one set of roller clamps. Each set of roller clamps includes two active rollers 23 spaced apart along a first direction. The first drive member 22 is located on the support. The axial direction of each active roller 23 extends along a third direction (e.g., the Y-axis direction) and is rotatably arranged on the support 21. A gap for clamping and pulling waste wire is formed between the two active rollers 23 in each set of roller clamps. The first drive member 22 drives the two active rollers 23 in each set of roller clamps to rotate in opposite directions.

[0043] The drive module 3 is used to drive the air blowing module 1 and the support 21 to move along the first direction, wherein the first direction and the third direction are two perpendicular directions in the horizontal plane, and the second direction is the vertical direction.

[0044] In the waste filament removal mechanism provided in this embodiment of the invention, after laser cutting, a carrier plate carrying the waste product to be removed is conveyed to the waste removal station. The carrier plate is then flipped so that the front of the waste product is facing down (i.e., the side of the carrier plate with the cutting grooves is facing down). Next, the drive module 3 drives the air blowing module 1 and the roller clamp module 2 to move along a first direction, and the air blowing module 1 and the roller clamp module 2 move sequentially below the waste product. Finally, for the air blowing module 1, as it passes under the waste product, the air blown through the air blowing holes 11 sweeps away the cutting grooves (i.e., compressed gas is blown upwards through the air blowing holes), causing the waste filaments to fall and detach from the cutting grooves. For the roller clamp module 2, as it passes under the waste product, the waste filaments fall into the gap between the two active rollers 23 in each set of roller clamps. The two active rollers 23 in each set of roller clamps cooperate to clamp and pull the waste filaments, causing them to completely detach from the cutting grooves. The cooperation of the air blowing module 1 and the roller clamp module 2 can improve the yield of conductive patterns while shortening the waste removal time and increasing the waste removal efficiency.

[0045] In other words, the waste filament removal mechanism provided in this embodiment of the utility model, through the sequential operation of the air blowing module and the roller clamping module, not only ensures the yield of conductive patterns after waste removal, but also saves a lot of waste removal time and improves production efficiency.

[0046] It should be noted that the air blowing module 1 can be set in front of the roller clamp module 2. During the process of removing waste yarn, the air blowing module 1 can be started first and then the roller clamp module 2 can be started, or the roller clamp module 2 can be started first and then the air blowing module 1 can be started, or the air blowing module 1 and the roller clamp module 2 can be started at the same time. This utility model does not make any specific limitations on it.

[0047] Alternatively, the air blowing module 1 and the support 21 can both be located on the same output end of the drive module 3. In other embodiments of this utility model, the drive module 3 may also include two power output mechanisms, one of which drives the air blowing module 1, and the other drives the roller clamp module 2.

[0048] In one implementation of this utility model, the first driving member 22 includes a driving unit 220 and at least two gears 231. One end of each active roller 23 is fitted with a gear 231, and two adjacent gears 231 mesh. The driving unit 220 is located on the support 21. The power output end of the driving unit 220 is connected to the other end of one of the active rollers 23, driving the active roller 23 to rotate.

[0049] In the above embodiment, through the cooperation of each gear 231, the active roller 23 connected to it is driven to rotate by a single drive unit 220, so that each active roller 23 can rotate and the rotation directions of two adjacent active rollers 23 are opposite, thereby making the two active rollers 23 in each set of roller clamps cooperate with each other to generate the power to clamp and pull the waste wire downward.

[0050] The drive unit 220 can be a motor, which can be directly connected to the drive roller 23. Alternatively, when installation space is limited and the motor's installation position needs adjustment, this invention can also achieve transmission between the motor and the drive roller 23 via a synchronous belt 222 and two synchronous pulleys 221.

[0051] In other embodiments of the present invention, the first driving member 22 may further include at least two driving units 220, each driving unit 220 driving the corresponding active roller 23 to rotate.

[0052] For example, each of the two ends of the drive roller 23 is fitted with a bearing 232, and the drive roller 23 is rotated and installed through the bearing 232.

[0053] See also Figure 2 and Figure 3 The waste filament removal mechanism also includes an air blowing drive module 4, which drives the air blowing module 1 to reciprocate along a third direction. The air blowing drive module 4 is connected to the output end of the drive module 3.

[0054] In the above embodiment, while the driving module 3 drives the air blowing driving module 4 and the air blowing module 1 to move forward synchronously, the air blowing driving module 4 can also drive the air blowing module 1 to move back and forth left and right to achieve repeated swinging air blowing and form an air sweeping effect, so that every cutting groove on the carrier plate is blown by the same amount of airflow, ensuring that waste wires are easily blown out and removed.

[0055] In addition, the waste filament removal mechanism also includes an outer cover 5, which is mounted on the air blowing module 1. The outer cover 5 covers the air blowing module 1 and the air blowing drive module 4. The side of the outer cover 5 facing the waste filament has multiple ventilation holes 51, which are arranged one-to-one with the multiple air blowing holes 11. The outer cover 5 serves to protect the air blowing module 1 and the air blowing drive module 4, preventing waste filaments from falling into the air blowing module 1 and the air blowing drive module 4 and becoming entangled.

[0056] In this embodiment, the air blowing drive module 4 includes a base 41, a second drive member 42, and a slide rail 43. The base 41 is driveably connected to the output end of the drive module 3. The second drive member 42 and the slide rail 43 are both located on the base 41. The output end of the second drive member 42 is driveably connected to the air blowing module 1 through a connecting block 44. The connecting block 44 and the slide rail 43 are slidably engaged, and the slide rail 43 extends in a third direction. The base 41 supports the second drive member 42 and the slide rail 43, the connecting block 44 connects the output end of the second drive member 42 and the air blowing module 1, and the slide rail 43 guides the sliding of the connecting block 44.

[0057] For example, the second driving component 42 can be a dual-axis slide cylinder, in which case two slide rails 43 and two connecting blocks 44 are respectively provided. The piston rod of the dual-axis slide cylinder is connected to the connecting block 44 through a connecting joint 421. The slide rail 43 is mounted on the base 41 through a slide rail connecting plate 431.

[0058] Furthermore, the air-blowing drive module 4 also includes a heightening block 45, on which the air-blowing module 1 is arranged. The heightening block 45 has a strip-shaped hole arranged along a second direction, and the connecting block 44 has multiple connecting holes arranged sequentially along the second direction. A connecting bolt for locking the heightening block 45 and the connecting block 44 is inserted into one of the strip-shaped holes and one of the connecting holes, thereby adjusting the height of the air-blowing module 1 by the cooperation of the strip-shaped hole and the connecting hole. Therefore, when it is necessary to adjust the distance between the air-blowing module 1 and the product to be removed, the strip-shaped hole and the connecting hole at the corresponding height can be locked together by the connecting bolt.

[0059] For example, the bottom of the air blowing module 1 is connected to the top of the raising block 45 via a connecting shaft 46.

[0060] For example, the bottom of the outer cover 5 is spaced apart from the base 41 to avoid interference between the outer cover 5 and the structural components on the base 41 during the movement of the outer cover 5 driven by the air blowing module 1. In addition, the outer cover 5 moves synchronously with the air blowing module 1, which can always ensure that the air blowing hole 11 and the vent hole 51 are aligned, and ensure that the airflow is blown out through the air blowing hole 11 and the vent hole at a high speed.

[0061] In addition, a mounting block 47 is provided below the base 41. The mounting block 47 is connected to the base 41 through multiple pads 48. The mounting block 47 can be used to easily connect the base 41 and the output end of the drive module 3.

[0062] In one implementation of this utility model, the air blowing module 1 includes an air plate 12 and an air pipe connector 13 disposed on the air plate 12. The air plate has an air cavity, and each air blowing hole 11 is disposed on the side of the air plate 12 facing the waste filament. The air cavity, each air blowing hole 11, and the air pipe connector 13 are all connected. The air pipe connector 13 receives compressed air, which is then buffered by the air cavity and evenly distributed to each air blowing hole 11 before being blown out, ensuring the consistency of the air blown from each air blowing hole 11.

[0063] For example, the air plate 12 includes a plurality of air distribution plate units connected in sequence, each air distribution plate unit having an air cavity for easy processing. The plurality of air distribution plate units are all mounted on the connecting shaft 46.

[0064] Furthermore, each air hole 11 is fitted with a nozzle 14, and a plug 15 can be inserted into some of the nozzles 14.

[0065] It is easy to understand that the nozzle 14 can ensure that the gas is blown out at high speed. By adjusting the number and position of the nozzles 14 and the plugs 15, the size and distribution of the blowing area can be adjusted. When adjusting, simply insert the plug 15 into the nozzle 14 that does not need to be vented.

[0066] For example, the plug 15 can also be inserted into the corresponding vent 51 to block the air blowing hole 11 that does not need to be vented.

[0067] In this embodiment, each set of roller clamps also includes two driven rollers 24. The two driven rollers 24 and the two driving rollers 23 in each set of roller clamps correspond one-to-one. Each driving roller 23 and the corresponding driven roller 24 are arranged in parallel at intervals along the second direction and are driven by a flat belt (that is, each flat belt 25 is sleeved on the corresponding driving roller 23 and the corresponding driven roller 24).

[0068] In the above embodiment, the surface of the flat belt 25 has a large coefficient of friction, which can better pull the waste filaments. During the rotation of the drive roller 23, the flat belt 25 is driven to rotate, thereby driving the driven roller 24 to rotate. In addition, through the cooperation of the drive roller 23 and the driven roller 24, the two flat belts 25 are tensioned to form a conveying path. The two conveying paths running inwards towards each other form a waste filament channel. The waste filaments fall to the two flat belts 25 near the drive roller 23 (i.e., they fall to the upper end of the waste filament channel). The rotation of the two flat belts 25 pulls the waste filaments in the waste filament channel downwards, so that the waste filaments pulled off the carrier are sent out from the side of the waste filament channel near the driven roller 24 (i.e., the lower end of the waste filament channel), thus preventing the waste filaments from tangling.

[0069] Of course, in this embodiment, the driven roller 24 can also be positioned above the driving roller 23, and the waste filaments can be pulled and conveyed from the end near the driven roller 24 to the end near the driving roller 23. This embodiment does not impose any specific limitations on this.

[0070] For example, in the second direction, the length of the waste filament is less than the length of the flat belt 25, so the flat belt 25 cannot be wound. This avoids the situation where a large amount of waste filament is wound on the roller clamp module 2, causing the waste removal height to be passively increased, and the wound waste filament comes into contact with the conductive pattern, causing it to be pulled and broken, resulting in product scrap.

[0071] Figure 6 This is a cross-sectional view of the roller clamp module provided in an embodiment of this utility model, as shown below. Figure 6 As shown, two sets of roller clamps can be set, meaning there can be four driving rollers 23, corresponding to four gears 231, four flat belts 25, and four driven rollers 24. The four gears 231 mesh sequentially, and under the drive of the first driving member 22, the corresponding gears 231 drive the other three gears to rotate. At this time, each set of roller clamps can rotate downwards inside the rollers, ensuring that the waste filaments can be "clamped" and conveyed downwards.

[0072] The four flat belts 25 are named 1#, 2#, 3#, and 4# respectively. There are gaps between flat belts 1# and 2# for pulling waste material, and there are gaps between flat belts 3# and 4# for pulling waste material, forming two sets of roller clamps for pulling waste material and improving the pulling rate. However, there are no gaps between flat belts 2# and 3#, and there is no need to pull waste material between them.

[0073] See Figure 4 and Figure 5 In one implementation of this utility model, each set of roller clamps further includes floating blocks 26 and adjusting blocks 27 disposed at both ends of the roller clamp module along a third direction. Each floating block is slidably inserted into the support along the first direction. Both ends of one active roller in each set of roller clamps are rotatably inserted into the corresponding floating block. The adjusting block is installed on the support, and a set screw is inserted into the adjusting block. One end of the set screw abuts against the corresponding floating block to drive the floating block to move.

[0074] In the above embodiment, the floating block 26 can be moved by the top screw, thereby pushing the corresponding active roller 23 to slide. This allows the gap between the two active rollers 23 in each set of roller clamps to be adjusted, thus adapting to the pulling of waste yarn of different sizes.

[0075] Furthermore, an elastic element is sandwiched between the top wire and the corresponding floating block 26. This elastic element can adapt to waste wires of different sizes. When the waste wire is large and pulled to the gap (i.e., the gap between the two flat belts 25), the waste wire can squeeze the corresponding drive roller 23 of the floating block 26 to move outward, and the elastic element is compressed, thus increasing the gap. When the waste wire is small, the elastic element can drive the floating block 26 and the corresponding drive roller 23 to return to their original position inward, thus decreasing the gap.

[0076] For example, the elastic element can be a spring.

[0077] It should be noted that during the above-mentioned adjustment of the clearance, it is necessary to control it within the permissible range of the mating clearance between adjacent gears 231 to ensure that gear 231 has the transmission capability.

[0078] In a preferred embodiment, both ends of the outermost active roller 23 in each set of roller clamps are connected to a floating block 26. The gap between the two active rollers 23 in a set of roller clamps is adjusted by adjusting the position of the outermost active roller 23.

[0079] Correspondingly, the support 21 includes a support shaft 212 and two spaced-apart fixed plates 211. The axial direction of the support shaft 212 is arranged along a third direction, and both ends of the support shaft 212 are perpendicularly connected to the fixed plates 211. Both ends of each drive roller 23 can be rotatably inserted into the fixed plates 211. The support shaft 212 separates and connects the two fixed plates 211 to form a whole, ensuring the stability of the rotation of each drive roller 23.

[0080] For example, the top of the fixed plate 211 has multiple openings. The ends of some of the drive rollers 23 are rotatably inserted into the corresponding openings, while other drive rollers 23 are inserted into the corresponding openings via corresponding floating blocks 26. Pressure strips 215 are correspondingly provided on the fixed plate 211 to seal each opening. In addition, the two ends of the adjusting block 27 are respectively fixed to the pressure strips 215 and the fixed plate 211 by bolts, and the gear 231 is located on the outside of the fixed plate 211.

[0081] For example, the support 21 also includes an adjusting plate 213 and a mounting plate 214. The adjusting plate 213 and the fixed plate 211 are respectively equipped with strip holes arranged along the second direction and multiple connecting holes arranged sequentially along the second direction. Similarly, the height of the fixed plate 211 relative to the adjusting plate 213 can be adjusted by inserting connecting bolts, thereby ultimately adjusting the pulling height of the drive roller 23. The mounting plate 214 and the adjusting plate 213 are fixedly connected, and the mounting plate 214 is fixed to the output end of the drive module 3.

[0082] In this embodiment, a baffle 28 is provided on the top edge of the support 21, and the baffle 28 is located on the side of the support 21 away from the moving direction of the support 21, and the baffle 28 is parallel to the drive roller 23.

[0083] In the above embodiment, the baffle 28 can block the waste filaments between the active rollers 23, allowing the active rollers 23 to fully pull the waste filaments, and at the same time, it can prevent the waste filaments from being blown to other positions in the waste removal area and thus preventing them from being removed.

[0084] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
