Description

Technical Field

[0001] This invention relates to the field of wiring harness production technology for new energy vehicles, specifically to a cable shielding mesh cutting device for new energy vehicles. Background Technology

[0002] When cutting cables with shielded mesh, radial cutting is generally not used because the metal mesh is difficult to cut and is prone to tangling or deformation during the cutting process. Therefore, axial cutting is more commonly used: The first step in shielded mesh cutting is to use cutting equipment to remove the outer insulation layer of the cable to be cut, exposing the shielded mesh. A tool is used to open the exposed front end of the shielded mesh. Then, a tubular blade is inserted between the shielded mesh and the inner layer and moved towards the blade base until the blade tip contacts the base. The shielded mesh is then cut between the blade base and the blade tip through compression. This axial cutting method minimizes damage to the inner layer. However, current cutting devices, due to structural design limitations, cannot accommodate the cutting of shielded meshes for a wider range of cable specifications, affecting work efficiency. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this invention is to provide a cable shielding mesh cutting device that can adapt to a wider range of cable specifications and has high cutting efficiency.

[0004] The technical solution for implementing the present invention is as follows:

[0005] The cable shielding mesh cutting device includes a base and a support platform. The base is arranged horizontally, and the support platform is slidably mounted on top of the base in a horizontal direction. A platform drive mechanism is provided above the base to drive the support platform to reciprocate along its sliding direction.

[0006] A first end support is fixedly installed at one end of the upper surface of the support platform, and a second end support is installed at the other end, forming an assembly space between the first end support and the second end support. The first end support and the second end support are arranged vertically on the upper surface of the support platform.

[0007] Two guide rods are arranged horizontally in the assembly space, and the two guide rods are arranged in parallel. The ends of the two guide rods are fixed on the first end support and the second end support, respectively.

[0008] A first moving part and a second moving part are slidably mounted on two guide rods, and the first moving part and the second moving part slide back and forth within the guide stroke of the guide rods;

[0009] The first moving part is equipped with a detachable rotating inner tube in the middle. A drive shaft is rotatably mounted between the middle of the first moving part and the middle of the second moving part, and a transmission connection is formed between the drive shaft and the rotating inner tube. The second moving part is equipped with a rotary drive mechanism that drives the drive shaft to rotate. The drive shaft and the rotating inner tube are arranged on the same axis. The rotation of the drive shaft can drive the rotating inner tube to rotate around its own axis. A forward and backward drive mechanism is provided above the support platform to drive the first moving part and the second moving part to reciprocate on the guide rod.

[0010] A cable threading hole is provided on the first end support, connecting both sides of the first end support. A seat outer tube that cooperates with the rotating inner tube is installed in the cable threading hole. A pressing component is provided on the first end support to press the cable shielding mesh that passes through the cable threading hole, so that the shielding mesh is lifted off the outer peripheral wall of the cable core.

[0011] The rotating inner tube extends into the inside of the raised shielding mesh, so that the raised shielding mesh is between the inner wall of the outer tube of the seat and the outer wall of the rotating inner tube. After the rotating inner tube extends into the outer tube of the seat, a cutting force is generated between the rotating inner tube and the outer tube of the seat on the shielding mesh.

[0012] In this application, the cable threading hole, the outer tube of the seat, the inner rotating tube, and the drive shaft are arranged with a coaxial centerline.

[0013] The first moving part has a horizontally arranged assembly hole in the middle. A first bearing is installed in the assembly hole. The outer ring of the first bearing is fixedly installed in the assembly hole. The inner ring of the first bearing is fitted with a fixing sleeve. The fixing sleeve has an installation channel for one end of the rotating inner tube to extend into.

[0014] One end of the fixed sleeve extends outside the first moving part and serves as a locking end; the other end of the fixed sleeve is located in the inner ring of the first bearing.

[0015] A locking structure is provided at the locking end of the fixed sleeve to lock the rotating inner tube inside the fixed sleeve; a sleeve is provided between the inner wall of the fixed sleeve and the outer wall of the rotating inner tube, and the other end of the rotating inner tube is arranged towards the cable threading hole.

[0016] In this application, the locking structure includes a locking sleeve with an internal thread on its inner wall, a locking thread on the outer circumferential surface of the locking end of the fixed sleeve, and the internal thread of the locking sleeve and the locking thread of the fixed sleeve are engaged to fit the locking sleeve onto the locking end of the fixed sleeve.

[0017] The outer circumference of the rotating inner tube located in the installation channel is provided with a stop part, and the locking sleeve is provided with a locking part that cooperates with the stop part to lock the rotating inner tube in the installation channel.

[0018] In this application, one end of the drive shaft is rotatably mounted to the middle of the second moving part via a second bearing, and the other end of the drive shaft is provided with a mounting flange. The mounting flange and the fixed sleeve are fixedly connected by a connector.

[0019] The rotary drive mechanism includes a rotary motor, a driving pulley, a driven pulley, and a transmission belt. The rotary motor is mounted on the second moving part, the driving pulley is mounted on the output end of the rotary motor, the driven pulley is mounted in the middle position of the drive shaft, and the transmission belt is arranged between the driving pulley and the driven pulley to form a transmission.

[0020] In this application, the forward and backward drive mechanism includes a forward and backward motor and a forward and backward drive rod. A support base is fixedly installed above the support platform. One end of the forward and backward drive rod is rotatably mounted on the support base, and the other end is rotatably mounted on the second end support. The forward and backward motor is located outside the second end support. The output shaft of the forward and backward motor is connected to the forward and backward drive rod. A forward and backward driving component is provided on the forward and backward drive rod and is driven to move by the forward and backward drive rod. The forward and backward driving component is connected to the first moving component and / or the second moving component.

[0021] A first limiting member is fixedly assembled on the outer side of the first end support, and a second limiting member is fixedly assembled on the inner side of the first end support. The first limiting member and the second limiting member respectively limit the two sides of the outer tube of the seat body to restrict the outer tube of the seat body in the cable threading hole.

[0022] The interior of the outer tube of the seat is a tapered cable routing channel that gradually narrows from the first limiting member toward the second limiting member along its axial direction. The minimum inner diameter of the cable routing channel is not less than the outer diameter of the cable shielding layer that extends into the cable routing channel.

[0023] The middle part of the first limiting member and the middle part of the second limiting member are respectively provided with clearance through holes for the cable. The clearance through holes, the cable routing channel and the rotating inner tube are arranged with a coaxial center line.

[0024] The pressing assembly is located inside the first end support. The pressing assembly presses the cable shielding mesh that extends into the inner side of the first end support through the cable routing channel, causing the shielding mesh to lift off the outer peripheral wall of the cable core, forming an annular insertion gap between the shielding mesh and the cable core for the rotating inner tube to insert.

[0025] In this application, a limiting part that protrudes toward the outer tube of the seat is formed on the inner side of the middle part of the first limiting member, and the end face of the limiting part forms a limiting position on the outer end of the outer tube of the seat.

[0026] The clearance through hole in the middle of the first limiting member includes a narrowed through hole and a straight through hole that communicates with the narrowed through hole. The narrowed through hole is arranged from the outside to the inside of the first limiting member. The diameter of the straight through hole is not greater than the minimum diameter of the narrowed through hole and the diameter of the straight through hole is not less than the maximum inner diameter of the wiring channel.

[0027] The outer circumferential surface of the outer tube of the seat is close to the outer peripheral surface of the second limiting member to form a stepped surface. The second limiting member is stuck on the stepped surface to limit the inner end of the outer tube of the seat.

[0028] In this application, a material collector for collecting the shielding mesh cut from the cable is provided on the inner side of the first end support. The material collector includes a primary receiving bin, which is assembled on the inner side of the first end support.

[0029] A drop-off mechanism is provided on one side of the bearing platform at the primary receiving hopper. The drop-off mechanism includes a support fixedly installed on the bearing platform and a drop-off plate detachably mounted on the support. The drop-off plate has a drop-off hole for the rotating inner tube to pass through. The gap between the inner wall of the drop-off hole and the outer wall of the rotating inner tube is smaller than the diameter of the cable shielding mesh.

[0030] Using the above technical solution, the cable is mounted on a clamping platform in a straight state. During the entire cutting process, when the cable is stationary, the platform drive mechanism moves the platform and its mechanisms toward the end of the cable where the shielding mesh needs to be cut. This allows one end of the cable to pass through the cable threading hole from the outside of the first end support, while the shielding mesh to be cut is located inside the first end support. The pressing assembly then presses down on the shielding mesh at that end of the cable, causing it to tilt upwards and creating an insertion gap between the shielding mesh and the cable core. The rotation drive mechanism drives the drive shaft and the inner rotating tube to rotate, moving the cable forward and backward. The drive mechanism moves the rotating inner tube toward the inner side of the first end support, so that the front end of the rotating inner tube enters the gap between the raised shielding mesh and the cable core. The cable core extends into the rotating inner tube. While the rotating inner tube rotates, it also moves toward the outer tube of the seat, reducing the resistance to the entry of the rotating inner tube. With the cooperation of the front end face of the rotating inner tube and the inner side of the outer tube of the seat, a cutting force is formed on the shielding mesh. After the shielding mesh is cut, the platform drive mechanism drives the entire platform to retract backward, and the forward and backward drive mechanism drives the rotating inner tube to retract and reset. At the same time, the cut shielding mesh follows the rotating inner tube to retract and is collected by the subsequent material collector. This invention, by simultaneously rotating the inner tube towards the cable shielding layer and the cable core, allows the inner tube to smoothly enter the insertion gap. Furthermore, the cooperation between the inner tube and the outer tube ensures the cutting of the shielding mesh. Additionally, the inner tube and outer tube can be replaced according to different cable specifications, increasing the adaptability of the cutting device. The entire cutting process is completed without manual intervention, avoiding safety hazards associated with manual operation and improving the efficiency of shielding mesh cutting.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1 As shown in Figure 8, the cable shielding mesh cutting device includes a base 10 and a support platform 11. The base 10 is arranged horizontally, and the support platform 11 is slidably mounted on top of the base 10. A base 12 is fixedly installed below the base 10, and the base 12 and the base 10 are fixedly connected by multiple spaced support columns 13. A reserved space of corresponding height to the support columns 13 is reserved between the upper surface of the base 12 and the lower surface of the base 10. Two slide rails 14 are fixedly installed horizontally on the upper surface of the base 10. The two slide rails 14 are arranged side by side and parallel. A slider 15 is mounted on each of the two slide rails 14. The slider 15 is fixedly connected to the lower surface of the support platform 11. A platform drive motor is provided above the base 10 to drive the support platform 11 to reciprocate along its sliding direction. The platform drive mechanism includes a first bracket 16, a second bracket 17, a platform motor 18, a platform drive screw 19, and a platform drive block 20. The first bracket 16 and the second bracket 17 are fixedly assembled on one end of the upper part of the base 10. The platform motor 18 is mounted on the first bracket 16. The platform drive screw 19 is connected to the output shaft of the platform motor 18 through a coupling. The platform drive screw 19 is rotatably assembled on the second bracket 17. The platform drive block 20 is assembled in the lower middle part of the support platform 11. The platform drive screw 19 and the platform drive block 20 form a threaded transmission connection. When the platform motor 18 is working, it drives the platform drive screw 19 to rotate. The rotation of the platform drive screw 19 can drive the platform drive block 20 to move, thereby driving the support platform 11 to reciprocate and slide on the slide rail.

[0042] A first end support 21 is fixedly installed at one end of the upper surface of the support platform 11, and a second end support 22 is installed at the other end, forming an assembly space between the first end support 21 and the second end support 22. The first end support 21 and the second end support 22 are arranged vertically on the upper surface of the support platform 11. Two guide rods 23 are arranged horizontally in the assembly space, and the two guide rods 23 are arranged in parallel. The two guide rods 23 are of the same length and have a smooth surface. The ends of the two guide rods 23 are fixedly installed on the first end support 21 and the second end support 22, respectively. A first moving part 24 and a second moving part 25 are slidably installed on the two guide rods 23. The first moving part 24 and the second moving part 25 slide back and forth within the guide stroke of the guide rods 23. Specifically, the first moving part 24 and the second moving part 25 are assembled on the guide rods 23 using sliding bushings 26.

[0043] A detachable rotating inner tube 27 is rotatably mounted in the middle of the first moving part 24. When a rotating inner tube 27 with a different inner diameter is needed, it can be quickly replaced by simply removing it. A drive shaft 28 is rotatably mounted between the middle of the first moving part 24 and the middle of the second moving part 25. The drive shaft 28 and the rotating inner tube 27 form a transmission connection. Under the action of the drive shaft 28, the rotating inner tube 27 can rotate around its own axis. The rotating inner tube 27 is a tubular cutter with a cutting end at its front end. When the rotating inner tube 27 rotates, the cutting end generates a cutting force. The inner diameter of the rotating inner tube is larger than the outer diameter of the cable core, so that the rotating inner tube can hold the cable core in the inner hole, thus protecting the cable core.

[0044] The second moving part 25 is equipped with a rotary drive mechanism that drives the drive shaft 28 to rotate. The rotary drive mechanism includes a rotary motor 29, a driving pulley 30, a driven pulley 31, and a transmission belt 32. The rotary motor 29 is mounted on the second moving part 25, the driving pulley 30 is mounted at the output end of the rotary motor 29, the driven pulley 31 is mounted at the middle position of the drive shaft 28, and the transmission belt 32 is arranged between the driving pulley 30 and the driven pulley 31 to form a transmission. When the rotary motor 29 is working, it drives the drive shaft 28 to rotate through the transmission of the driving pulley 30, the transmission belt 32, and the driven pulley 31. The inner ring of the transmission belt 32 has transmission teeth, and the driving pulley 30 and the driven pulley 31 are gears. The transmission belt 32 and the driving and driven pulleys 31 are connected by teeth to increase the stability of the transmission.

[0045] The drive shaft 28 is arranged coaxially with the rotating inner tube 27. The rotation of the drive shaft 28 can stably drive the rotating inner tube 27 to rotate around its own axis. A forward and backward drive mechanism is provided above the support platform 11 to drive the first moving part 24 and the second moving part 25 to reciprocate on the guide rod. The forward and backward drive mechanism includes a forward and backward motor 33 and a forward and backward drive rod 34. A support base 35 is fixedly installed above the support platform 11. One end of the forward and backward drive rod 34 is rotatably mounted on the support base 35 through a bearing, and the other end is rotatably mounted on the second end support 22 through a bearing. The forward and backward motor 33 is located outside the second end support 22. The output shaft of the forward and backward motor 33 is connected to the forward and backward drive rod 34 through a coupling. A forward and backward drive member 36 is provided on the forward and backward drive rod 34 and is driven by the forward and backward drive rod 34. The forward and backward drive member 36 is connected to the first moving part 24 and / or the second moving part 25. In this application, the forward / backward drive rod 34 is a screw, and the forward / backward drive component 36 is a threaded drive block that is threadedly connected to the forward / backward drive cylinder to form a transmission. The forward / backward drive component 36 can be mounted below the first moving component 24 and / or the second moving component 25 to perform transmission.

[0046] A cable threading hole 37 is provided in the middle of the first end support 21, connecting the inner and outer sides of the first end support 21. A seat outer tube 38, which mates with the rotating inner tube 27, is installed inside the cable threading hole 37. The cable threading hole 37, seat outer tube 38, rotating inner tube 27, and drive shaft 28 are arranged coaxially. The interior of the seat outer tube 38 is a channel for the cable to enter. After the cable enters this channel, the cable, seat outer tube 38, and rotating inner tube 27 are arranged coaxially. When the drive shaft 28 drives the rotating inner tube 27 to rotate, the rotating inner tube 27 moves towards the seat outer tube 38, causing the front end of the rotating inner tube 27 to engage with the seat outer tube 38 to generate a cutting force. That is, the seat outer tube 38 is equivalent to a cutter holder, and with the cooperation of the seat outer tube and the rotating inner tube, it can cut the shielding mesh between them.

[0047] To ensure the smooth insertion of the rotating inner tube 27 into the inner side of the shielding mesh, a pressing assembly is provided on the first end support 21 to press the cable shielding mesh that passes through the cable threading hole 37, causing the shielding mesh to lift off the outer peripheral wall of the cable core. The pressing assembly includes a pressing motor 39, a first pressing block 40, and a second pressing block 41. The first pressing block 40 and the second pressing block 41 are slidably mounted on a pressing bracket 42 via a slide rail slider. The pressing motor 39 is driven to move closer or further apart. Three pressing plates 43 are installed on the first pressing block 40 and the second pressing block 41 respectively. The pressing plates 43 on the first pressing block 40 and the second pressing block 41 form a pressing opening that converges towards the center to press the shielding mesh 70 of the cable 69. This causes the shielding mesh 70 at the cable end to bend upwards and expand, thus forming an annular insertion gap between the inner side of the shielding mesh and the outer side of the cable core, allowing the rotating inner tube 27 to extend into it. Specifically, the pressing assembly is located inside the first end support 21. The pressing assembly presses the cable shielding mesh that extends through the cable routing channel to the inner side of the first end support 21, causing the shielding mesh to bend upwards from the outer peripheral wall of the cable core, forming an annular insertion gap between the shielding mesh and the cable core, allowing the rotating inner tube 27 to extend into it.

[0048] During the cutting process, under the action of the forward and backward drive mechanism and the rotation drive mechanism, the rotating inner tube 27 rotates and extends into the inside of the raised shielding net, so that the raised shielding net is between the inner wall of the outer tube 38 of the seat and the outer wall of the rotating inner tube 27. After the rotating inner tube 27 extends into the outer tube 38 of the seat, the front end of the rotating inner tube 27 contacts the outer tube 38 of the seat, thereby generating a cutting force on the shielding net between the rotating inner tube 27 and the outer tube 38 of the seat to cut the shielding net. After cutting, the shielding net remains in a ring state. When the rotating inner tube 27 moves backward, the shielding net is taken out along with the rotating inner tube 27.

[0049] The first moving part 24 has a horizontally arranged assembly hole 44 in the middle. A first bearing 45 is installed in the assembly hole 44. The outer ring of the first bearing 45 is fixedly installed in the assembly hole 44. The inner ring of the first bearing is fitted with a fixing sleeve 46. The fixing sleeve 46 has an installation channel for one end of the rotating inner tube 27 to extend into. One end of the fixing sleeve 46 extends out of the first moving part 24 as a locking end. The other end of the fixing sleeve 46 is located in the inner ring of the first bearing.

[0050] A locking structure is provided at the locking end of the fixed sleeve 46 to lock one end of the rotating inner tube 27 inside the fixed sleeve 46; a sleeve 47 is provided between the inner wall of the fixed sleeve 46 and the outer wall of the rotating inner tube 27, and the other end of the rotating inner tube 27 is arranged towards the cable threading hole 37. The inner diameter of the sleeve 47 is adapted to the outer diameter of the rotating inner tube 27, and the outer diameter of the sleeve 47 is adapted to the inner diameter of the fixed sleeve 46. The sleeve 47 is used for rotating inner tubes 27 with different outer diameters to compensate for the excess gap between the outer wall of the rotating inner tube 27 and the inner wall of the fixed sleeve, so that the sleeve 47 with different wall thicknesses can be used to adapt to rotating inner tubes 27 with different outer diameters. The appropriate rotating inner tube 27 can be selected according to the needs of the cable outer diameter, thereby improving the corresponding adaptability.

[0051] The locking structure includes a locking sleeve 48 with internal threads on its inner wall, and a locking thread on the outer circumferential surface of the locking end of the fixed sleeve 46. The internal thread of the locking sleeve 48 mates with the locking thread of the fixed sleeve 46, allowing the locking sleeve 48 to be fitted onto the locking end of the fixed sleeve 46. A stop portion 49 is provided on the outer circumference of the rotating inner tube 27 located within the installation channel. A locking portion 50, which mates with the stop portion 49, is provided in the middle of the locking sleeve 48 to lock the rotating inner tube 27 within the installation channel. Specifically, the stop portion 49 is formed by an annular step on the outer circumference of the rotating inner tube 27, and the middle of the locking sleeve 48 blocks the outer side of the annular step, thus limiting the axial movement of the rotating inner tube 27. A tool operating groove is provided on the outside of the locking sleeve 48. By using a tool fitted over the locking sleeve 48 and rotating it, the locking sleeve 48 can be removed, allowing the rotating inner tube 27 to be replaced. The operation is convenient. The other end of the rotating inner tube 27 is limited by the following structure: the end face of the rotating inner tube 27 rests on the drive shaft 28. In order to ensure the coaxiality between the rotating inner tube 27 and the drive shaft 28, a protrusion 51 is provided at the center of the rotating inner tube 27. The inside of the drive shaft 28 is a through hole for the protrusion to be inserted. After the protrusion 51 is inserted into the through hole, the rotating inner tube 27 and the drive shaft 28 are arranged in a coaxial manner.

[0052] One end of the drive shaft 28 is rotatably mounted to the middle of the second moving part 25 via the second bearing 52, and the other end of the drive shaft is provided with a mounting flange 53. The mounting flange 53 and the fixed sleeve 46 are fixedly connected by a screw connector 54, so that the rotation of the drive shaft 28 can drive the rotation of the fixed sleeve 46, and the rotation of the fixed sleeve 46 can drive the rotation of the inner tube 27.

[0053] A first limiting member 55 is fixedly mounted on the outer side of the first end support 21, and a second limiting member 56 is fixedly mounted on the inner side of the first end support 21. The first limiting member 55 and the second limiting member 56 respectively limit the two sides of the outer tube 38 of the seat body to restrict the outer tube 38 of the seat body to the cable threading hole 37. The first limiting member 55 is mounted on the outer side of the first end support 21 with screws, which can be easily removed from the first end support 21. After the first limiting member 55 is removed, the outer tube 38 of the seat body can be removed and replaced with a seat body outer tube 38 of different diameters so that the outer tube 38 of the seat body can be adapted to the rotating inner tube 27.

[0054] The interior of the outer tube 38 of the seat is a tapered cable routing channel 57 that gradually narrows from the first limiting member 55 toward the second limiting member 56 along its axial direction, so as to better guide the cable into the cable routing channel 57. The minimum inner diameter of the cable routing channel 57 is not less than the outer diameter of the cable shielding layer that extends into the cable routing channel. The middle part of the first limiting member 55 and the middle part of the second limiting member 56 are respectively provided with clearance through holes 58 for the cable. The clearance through holes 57, the cable routing channel 58 and the rotating inner tube 27 are arranged coaxially.

[0055] The inner side of the middle portion of the first limiting member 55 forms a limiting portion 59 that protrudes towards the outer tube 38 of the seat body. The end face of the limiting portion 59 limits the outer end of the outer tube 38 of the seat body. The clearance through hole in the middle of the first limiting member 55 includes a narrowed through hole 60 and a straight through hole 61 that communicates with the narrowed through hole 60. The narrowed through hole 60 is arranged from the outside to the inside of the first limiting member 55. The diameter of the straight through hole 61 is not greater than the minimum diameter of the narrowed through hole and not less than the maximum inner diameter of the cable routing channel. The arrangement of the narrowed through hole and the straight through hole guides the insertion of the cable. The outer circumferential surface of the outer tube 38 near the second limiting member 56 forms a stepped surface 62. The second limiting member 56 is locked on the stepped surface 62, limiting the inner end of the outer tube 38 of the seat body. The second limiting member 56 is installed on the inner side of the first end support 21 through a detachable connector.

[0056] A material collector for collecting the shielding mesh cut from the cable is provided inside the first end support 21. The material collector includes a primary receiving bin 63, which is mounted inside the first end support 21. A deflector mechanism is provided on the support platform 11 on one side of the primary receiving bin 63. The deflector mechanism includes a support 64 fixedly installed on the support platform 11 and a deflector plate 65 detachably mounted above the support 64. The deflector plate 65 has a deflector hole 66 for the rotating inner tube 27 to pass through. The gap between the inner wall of the deflector hole 66 and the outer wall of the rotating inner tube 27 is smaller than the diameter of the cable shielding mesh. The deflector plate is installed on the support using a strip-shaped hole and bolt adjustment, allowing for adjustment of the deflector plate's height. As the rotating inner tube 27 moves backward with the cut shielding mesh, the shielding mesh is peeled off from the rotating inner tube 27 by the deflector and falls into the primary receiving bin. Below the primary receiving bin are the secondary receiving bin 67 and the tertiary receiving bin 68. Both receiving bins are open at the top and bottom. The secondary receiving bin 67 and the tertiary receiving bin 68 are fixedly mounted on the base 10, forming an up-down arrangement. When the shielding mesh is removed from the rotating inner tube 27 onto the glass, the primary receiving bin 63 is exactly above the secondary receiving bin 67. Thus, the shielding mesh in the primary receiving bin 63 can enter the secondary receiving bin 67, while the shielding mesh in the secondary receiving bin 67 will enter the tertiary receiving bin 68 and be discharged outside the device.

[0057] The support platform 11, the first end support 21, and the second end support 22 all adopt a weight-reducing hollow design to reduce their respective weight and reduce the corresponding driving force of the platform drive mechanism.
