Description

Technical Field

[0001] This invention relates to the field of agricultural equipment technology, and in particular to a slicing device. Background Technology

[0002] Most existing slicing equipment can only perform cutting operations on one type of target, and the cut shape is basically the same, unable to be varied, with a narrow range of applications and unable to be used in multiple scenarios. For example: Scenario 1: When feeding silkworms with artificial feed, the size of the feed needs to be adjusted according to the silkworm's age. In the early stages of silkworms, the feed should be finer and smaller; in the later stages, the feed should be larger. Currently, the entire silkworm feeding process is almost entirely manual, using a method of shaving the feed. This involves holding a piece of steamed powdered feed above the silkworm basket and manually shaving it into strips with a simple plastic cutter, allowing the feed to fall into the basket in strips for feeding. Alternatively, steamed brick-shaped feed can be shaved into strips and placed in a container, then sprinkled into the silkworm basket by hand. This method is extremely inefficient, therefore, a mechanized method is needed to slice the artificial feed for silkworms. Scenario 2: Many root and tuber crops can increase their yield by using seed tuber cutting and planting. For example, yam growers need to prepare seed potatoes before planting yams. These seed potatoes need to be cut because each seed potato has only one apical bud, and yams cannot grow from a single bud. Therefore, the seed potatoes need to be processed. When cutting, they should be longitudinally cut into small pieces, each 5 cm long and wide, and 2 cm thick (approximately 100 grams), with each piece having a apical bud. This improves the germination and emergence rate, thus increasing yam yield. However, the tubers need to be precisely cut by hand, and the cutting requirements differ depending on the type of yam seed potato. This process is time-consuming, labor-intensive, and requires a high level of skill and experience. Therefore, the cutting thickness varies depending on the specific circumstances. Furthermore, the current method of vertically slicing directly on a conveyor belt can damage the conveyor belt.

[0003] In summary, existing slicing equipment has limited functionality and a narrow range of applications, making it unsuitable for use in various scenarios. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the above-mentioned problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a slicing device, comprising:

[0012] The second transmission assembly is the cutter drive shaft that connects the powertrain and the cutter assembly;

[0013] The powertrain drives the lower drive belt and the pressure belt to move forward synchronously, conveying the material to the outlet of the lower drive belt. The powertrain drives the cutter to swing forward along an arc-shaped swing trajectory at the outlet of the lower drive belt, thereby cutting the protruding material at the outlet of the lower drive belt. The cutter swings in the opposite direction along the swing trajectory, thereby completing one cut. The first transmission assembly can adjust the step distance of the lower drive belt and the pressure belt, and the second transmission assembly can adjust the diameter of the swing trajectory of the cutter to adjust the cutting thickness.

[0014] In one embodiment of the present invention, there are two first transmission assemblies, which are symmetrically arranged on both sides of the pressing assembly along the width direction of the pressing belt. The first transmission assembly includes a first transmission shaft, an eccentric adjustable wheel, a first joint bearing, a first connecting rod, and a second joint bearing. One end of the first transmission shaft is connected to the power assembly, and the other end is connected to one side of the eccentric adjustable wheel. The other side of the eccentric adjustable wheel is connected to the first joint bearing, and the eccentric distance of the first joint bearing on the eccentric adjustable wheel is adjustable. The two ends of the first connecting rod are respectively connected to the first joint bearing and the second joint bearing, and the second joint bearing is connected to the second transmission assembly.

[0015] In one embodiment of the present invention, the first transmission assembly further includes an eccentric adjustment fixing block, an eccentric adjustment moving block, and an eccentric adjustment screw; the eccentric adjustment fixing block is fixed to one side of the eccentric adjustable wheel, and the eccentric adjustment fixing block is provided with a sliding groove; along the length direction of the sliding groove, the eccentric adjustment fixing block is provided with two through holes communicating with the sliding groove; the eccentric adjustment moving block is disposed in the sliding groove and connected to the first joint bearing, and the eccentric adjustment moving block is provided with a threaded hole; the eccentric adjustment screw passes through the two through holes and the sliding groove and is threadedly connected to the threaded hole; the eccentric adjustment screw is connected with a nut.

[0016] In one embodiment of the present invention, the second transmission assembly includes a pressing drive roller, a pressing belt circular guide rail, and a pressing rear adjustment roller; the pressing drive roller is rotatably connected to the frame and connected to the first transmission assembly, the pressing belt circular guide rail is connected to the frame and located at the front end of the pressing assembly, and the pressing rear adjustment roller is rotatably connected to the frame and located at the rear end of the pressing assembly; the pressing belt is wound around the pressing drive roller, the pressing belt circular guide rail, and the pressing rear adjustment roller.

[0017] In one embodiment of the present invention, the second transmission assembly further includes a forward ratchet and a backward ratchet respectively connected to both ends of the pressing drive roller, the forward ratchet and the backward ratchet having opposite transmission directions; the forward ratchet and the backward ratchet are respectively connected to the second joint bearings of the two first transmissions.

[0018] In one embodiment of the present invention, the first transmission assembly includes a lower belt drive driving roller and a lower belt drive driven roller, the lower belt drive driving roller and the lower belt drive driven roller are rotatably connected to the frame respectively, the lower belt drive driving roller is connected to the first transmission assembly, and the lower transmission belt is wound around the lower belt drive driving roller and the lower belt drive driven roller.

[0019] In one embodiment of the present invention, the first transmission assembly further includes a lower belt drive pressure roller, which is located between the lower belt drive driving roller and the lower belt drive driven roller along the height direction and the material transmission direction.

[0020] In one embodiment of the present invention, the first transmission assembly further includes a lower belt circular guide rail fixedly connected to the frame, the lower belt circular guide rail being disposed at the front end of the slicing equipment; along the material transmission direction, the lower belt drive drive roller is located between the lower belt drive driven roller and the lower belt circular guide rail; the lower transmission belt is wound around the lower belt drive driven roller, the lower belt circular guide rail and the lower belt drive drive roller.

[0021] In one embodiment of the present invention, the powertrain includes an electric motor connected to a first transmission assembly and a second transmission assembly.

[0022] In one embodiment of the present invention, there are two second transmission assemblies, which are symmetrically arranged on both sides of the cutter assembly. Each second transmission assembly includes an eccentric wheel, a second connecting rod, a third joint bearing, and a fourth joint bearing. The eccentric wheel is rotatably connected to the frame. The eccentric wheels of the two second transmission assemblies are coaxially connected. One end of the second connecting rod is connected to one side of the eccentric wheel through the third joint bearing, and the eccentric distance of the second connecting rod on the eccentric wheel is adjustable. The other end of the second connecting rod is connected to the cutter drive shaft through the fourth joint bearing.

[0023] The technical solution of the present invention has the following advantages compared with the prior art:

[0024] In the slicing device described in this invention, during the material transport process on the lower drive belt, the pressing assembly applies a certain clamping force to the material. This embodiment also includes a cutter assembly at the outlet of the lower drive belt. Driven by the power assembly, the pressing belt and the lower drive belt move synchronously via the first transmission assembly, causing the material to advance a certain distance, thus conveying the material to the outlet of the lower drive belt. Then, driven by the power assembly, the cutter oscillates along a circular swing trajectory at the outlet of the lower drive belt via the second transmission assembly, thereby performing oscillating cutting on the material at the outlet of the lower drive belt. This differs from the method of vertical slicing directly on the conveyor belt. In this embodiment, the cutter does not contact the lower drive belt during cutting, thus preventing damage to the conveyor belt. Furthermore, the circular swing trajectory of the cutter reduces material deformation and residual stress during cutting, helping to maintain the quality of the cut surface. Additionally, by adjusting the step distance of the lower drive belt and the pressing belt, the cutting thickness of the material can be adjusted to suit different needs of slicing or cutting into segments.

[0047] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0048] See Figures 1 to 8 This invention provides a slicing device, comprising:

[0049] The components include: frame 1, lower conveyor belt assembly 2, material guide assembly 3, first transmission assembly 4, second transmission assembly 5, belt tensioning assembly 6, power assembly 7, pressing assembly 8, cutter assembly 9, discharge baffle 10, photoelectric sensor 11, second tensioning wheel 12, electrical control box 13, and emergency stop button 14.

[0050] The frame 1 is welded from square steel and steel plate with mounting holes, ensuring reliable strength.

[0051] The lower conveyor belt assembly 2 is used to transport materials. The lower conveyor belt assembly 2 includes a first transmission component connected to the frame 1 and a lower transmission belt 201 wound around the first transmission component.

[0052] The pressing assembly 8 is located above the lower conveyor belt assembly 2 and is used to press the material. The pressing assembly 8 includes a second transmission assembly connected to the frame 1 and a pressing belt 801 wound around the second transmission assembly;

[0053] The cutter assembly 9 includes a cutter 901, two cutter holders 902, a cutter fixing shaft 903, a cutter fixing bearing seat 904, a cutter inner support shaft 905, and a cutter drive shaft 906. The cutter 901 is located at the front end of the lower conveyor belt assembly 2 and the pressing assembly 8, and is positioned at the exit of the lower drive belt 201. The two cutter holders 902 are connected to both sides of the cutter 901, with the cutter 901 located at the front end of the cutter holders 902. The cutter drive shaft 906 is connected to the middle of the cutter holders 902. The rear end of the cutter holders 902 is rotatably connected to the frame 1. For example, the cutter assembly 9 also includes a cutter fixing shaft 903 and a cutter fixing bearing seat 904. The two cutter holders 902 are rotatably connected to both sides of the cutter fixing shaft 903 via the cutter fixing bearing seat 904 and bearings. The cutter fixing shaft 903 is connected to the frame 1. In some embodiments, an inner support shaft 905 is also connected between the two blade holders 902, which fixes the two blade holders 902 together, improving the overall stability of the entire cutter assembly 9. The cutter 901 is available in various specifications and is detachably connected to the blade holder 902. The cutter 901 is replaceable to accommodate slices of different materials and thicknesses. See also... Figure 9 Three different cutting blades 901 are provided (but not limited to these three): a smooth long blade, a mesh-like blade with multiple rows of vertical blades, and a blade with evenly distributed rows of planer holes. The blades are fixed to the blade holder 902 with screws, facilitating the replacement of different blade sizes.

[0054] The power assembly 7 is connected to the frame 1 and is configured to provide power to the downward conveyor assembly 2, the pressing assembly 8 and the cutting assembly 9;

[0055] The first transmission assembly 4 connects the power assembly 7 and the pressing assembly 8;

[0056] The second transmission assembly 5 connects the power assembly 7 and the cutter assembly 9 via a cutter drive shaft 906;

[0057] In this system, the power assembly 7 drives the lower transmission belt 201 and the pressure belt 801 to advance synchronously. The material is placed on the lower transmission belt 201 and transported forward. The pressure assembly 8 applies a certain pressure to the material to ensure that it can be sliced ​​smoothly. The material at the front end is conveyed to the outlet of the lower transmission belt 201. The power assembly 7 drives the cutter 901 to swing forward along an arc-shaped swing trajectory at the outlet of the lower transmission belt 201, thereby cutting the protruding material at the outlet of the lower transmission belt 201. The cutter 901 swings along the swing trajectory to complete one cut. The first transmission assembly 4 can adjust the step distance of the lower transmission belt 201 and the pressure belt 801, and the second transmission assembly 5 can adjust the diameter of the swing trajectory of the cutter 901 to adjust the cutting thickness.

[0058] In some embodiments, this application further includes a discharge baffle 10, which is screwed onto the outlet (i.e., located below the cutter 901). The cut material is then guided by the discharge baffle 10 and falls into the relevant container.

[0059] Specifically, in this embodiment, during the material transport process placed on the lower drive belt 201, the pressing assembly 8 can apply a certain clamping force to the material. This embodiment also includes a cutter assembly 9 at the outlet of the lower drive belt 201. Thus, driven by the power assembly 7, the pressing belt 801 and the lower drive belt 201 move synchronously through the first transmission assembly 4, causing the material to advance a distance, thereby conveying the material at the front end to the outlet of the lower drive belt 201. Then, driven by the power assembly 7, the cutter 901 is driven by the second transmission assembly 5 to swing along a circular oscillating trajectory at the outlet of the lower drive belt 201, thereby performing oscillating cutting on the material at the outlet of the lower drive belt 201. This differs from the method of directly slicing vertically on the conveyor belt. In this embodiment, the cutter 901 does not contact the lower drive belt 201 during cutting, thus preventing damage to the conveyor belt. Furthermore, the oscillating of the cutter 901 along a circular oscillating trajectory reduces material deformation and residual stress during cutting, helping to maintain the quality of the cut surface. In addition, the cutting thickness of the material can be adjusted by adjusting the stepping distance of the lower drive belt 201 and the pressing belt 801 to suit different needs of slicing or cutting.

[0060] This invention is a slicing device applicable to multiple scenarios, which can replace the cutter 901 to achieve oscillating slicing.

[0061] Furthermore, there are two first transmission assemblies 4, symmetrically arranged on both sides of the pressing assembly 8 along the width direction of the pressing belt 801. Each first transmission assembly 4 includes a first transmission shaft 402, an eccentric adjustable wheel 404, a first spherical bearing 407, a first connecting rod 408, and a second spherical bearing 409. One end of the first transmission shaft 402 is connected to the power assembly 7, and the other end is connected to one side of the eccentric adjustable wheel 404. In some embodiments, the first transmission shaft 402 is connected to the frame 1 via a first bearing seat 403 and a bearing. The other side of the eccentric adjustable wheel 404 is connected to the first connecting rod 408 via the first spherical bearing 407, and the eccentricity of the first spherical bearing 407 on the eccentric adjustable wheel 404 is adjustable. The other end of the first connecting rod 408 is connected to the second spherical bearing 409, which is connected to the pressing drive roller 802 of the second transmission assembly (described later). Specifically, in this embodiment, the rotation of the eccentric adjustable wheel 404 drives the pressing drive roller 802 to reciprocate, thereby driving the lower transmission belt 201 and the pressing belt 801 to move synchronously.

[0062] Furthermore, the first transmission assembly 4 also includes an eccentric adjustment fixing block 405, an eccentric adjustment moving block 406, and an eccentric adjustment screw 410. The eccentric adjustment fixing block 405 is fixed to one side of the eccentric adjustable wheel 404 by screws, and the eccentric adjustment fixing block 405 is provided with a sliding groove 4051; along the length direction of the sliding groove 4051, the eccentric adjustment fixing block 405 is provided with two through holes communicating with the sliding groove 4051; the eccentric adjustment moving block 406 is disposed in the sliding groove 4051 and connected to the first joint bearing 407, and the eccentric adjustment moving block 406 is provided with a threaded hole; the eccentric adjustment screw 410 passes through the two through holes and the sliding groove 4051 and is threadedly connected to the threaded hole; the eccentric adjustment screw 410 is connected with a nut. Specifically, in this embodiment, the eccentricity adjustment moving block 406 slides in the slide groove 4051 by rotating the eccentricity adjustment screw 410, thereby adjusting the eccentricity distance of the first joint bearing 407 on the eccentric adjustable wheel 404, and thus realizing the adjustment of the step distance. In some embodiments, the two ends of the first connecting rod 408 (i.e., the positions where it connects to the first joint bearing 407 and the second joint bearing 409) are set with positive and negative threads, which can realize the adjustment of the length of the first connecting rod 408 within a certain range, and further realize the adjustment of the step distance.

[0063] Further, the second transmission assembly includes a pressing drive roller 802, a first tension roller shaft 803, a pressing belt circular guide rail 804, and a pressing rear adjustment roller 806. The pressing drive roller 802 is rotatably connected to the frame 1 via an adjusting bearing seat 810 and a bearing, and is connected to the first transmission assembly 4. The pressing belt circular guide rail 804 is connected to the frame 1 and located at the front end of the pressing assembly 8. The pressing rear adjustment roller 806 is rotatably connected to the frame 1 and located at the rear end of the pressing assembly 8. In some embodiments, the pressing assembly 8 also includes two pressing side mounting plates 807 symmetrically arranged on both sides of the pressing belt 801. The pressing side mounting plates 807 are connected to the frame 1; the pressing drive roller 802 and the pressing rear adjustment roller 806 are rotatably connected to the pressing side mounting plates 807, and the pressing belt circular guide rail 804 is fixedly connected to the pressing side mounting plates 807. The pressure belt 801 is wound around the pressure drive roller 802, the pressure belt circular guide rail 804, and the pressure adjustment roller 806. This allows the pressure belt 801 to form a portion parallel to the upper part of the lower drive belt 201 between the pressure belt circular guide rail 804 and the pressure adjustment roller 806; this portion is used for pressure. Furthermore, the arrangement of the pressure belt circular guide rail 804 ensures that the front end of the pressure assembly 8 is as close as possible to the cutting point, achieving better cutting results.

[0064] In some embodiments, the pressing assembly 8 further includes a front adjusting screw 809 and a rear adjusting screw 808 respectively located at the front and rear ends of the pressing assembly 8, for adjusting the tension of the pressing belt 801. The rear adjusting screw 808 and the front adjusting screw 809 have the same structure, that is, both include a fixing member and a tightening screw threaded onto the fixing member. The fixing member is fixedly connected to the end of the pressing side mounting plate 807. The end of the pressing side mounting plate 807 is provided with an adjusting hole. The tightening screw abuts against the rear side of the pressing belt circular guide rail 804 (i.e., the tightening screw of the front adjusting screw 809) or the tightening screw abuts against the front side of the pressing rear adjusting roller 806 (i.e., the tightening screw of the rear adjusting screw 808).

[0065] Furthermore, the second transmission assembly also includes a forward ratchet 812 and a backward ratchet 811 respectively connected to both ends of the pressure drive roller 802. The pressure drive roller 802 is connected to the ratchet (forward ratchet 812 and backward ratchet 811) via a key. The forward ratchet 812 and the backward ratchet 811 have opposite transmission directions; the forward ratchet 812 and the backward ratchet 811 are respectively connected to the second joint bearings 409 of the two first transmissions. Specifically, the ratchet can achieve unidirectional intermittent motion. The forward ratchet 812 and the backward ratchet 811 have opposite transmission directions, so when the forward ratchet 812 is active, the backward ratchet 811 is in an idle state; when the forward ratchet 812 is in an idle state, the backward ratchet 811 is active (the backward ratchet 811 drives the pressure belt 801 and the lower transmission belt 201 backward). In other words, the forward ratchet 812 causes the pressure belt 801 and the lower drive belt 201 to advance a certain distance, thereby conveying the front end of the material to the outlet of the lower drive belt 201, waiting for cutting. After cutting, the reverse ratchet 811 drives the pressure belt 801 and the lower drive belt 201 to retreat, retracting the material and avoiding damage to the material by the cutter 901 during the retraction process. In addition, the material is retracted a small distance after each cut to avoid scraping by the cutter and achieve better cutting results. In some embodiments, the forward advance distance is adjusted by adjusting the eccentricity of the first joint bearing 407 corresponding to the forward ratchet 812 on the eccentric adjustable wheel 404; the reverse advance distance is adjusted by adjusting the eccentricity of the first joint bearing 407 corresponding to the reverse ratchet 811 on the eccentric adjustable wheel 404, so that the forward advance distance minus the reverse advance distance equals the cutting thickness during use.

[0066] Furthermore, the first transmission assembly includes a lower belt drive drive roller 205 and a lower belt drive driven roller 202. The lower belt drive drive roller 205 and the lower belt drive driven roller 202 are rotatably connected to the frame 1, respectively. The lower belt drive drive roller 205 is connected to the first transmission assembly 4, and the lower transmission belt 201 is wound around the lower belt drive drive roller 205 and the lower belt drive driven roller 202.

[0067] Furthermore, the first transmission assembly also includes a lower belt drive pressure roller 206, which is located between the lower belt drive driving roller 205 and the lower belt drive driven roller 202 along both the height direction and the material transmission direction. Specifically, the lower belt drive pressure roller 206 can lift the belt (the belt located at the lower position in the lower transmission belt 201) between the lower belt drive driving roller 205 and the lower belt drive driven roller 202 upwards, thereby preventing the belt from drooping down and interfering with other components, making the structure of this equipment compact.

[0068] Furthermore, the first transmission assembly also includes a lower belt circular guide rail 204 fixedly connected to the frame 1, which is located at the front end of the slicing device. Along the material transmission direction, the lower belt drive drive roller 205 is located between the lower belt drive driven roller 202 and the lower belt circular guide rail 204. The lower transmission belt 201 is wound around the lower belt drive driven roller 202, the lower belt circular guide rail 204, and the lower belt drive drive roller 205. Specifically, after the material has traveled a certain distance, the material at the front end (i.e., the material segment to be cut) will detach from the lower transmission belt 201 and remain suspended at the front end of the lower transmission belt 201. The cutter 901 also cuts the material segment outside the lower transmission belt 201. Because the material segment is suspended, the cutting is affected. Using a driven roller would result in a larger diameter, increasing the unloaded space below the material at that location. Therefore, this embodiment replaces the driven roller with a lower belt circular guide rail 204, which has the smallest possible diameter. This minimizes the radius of the lower drive belt 201 at the cutting section, reducing the gap below. Furthermore, the lower drive belt 201 and the lower belt circular guide rail 204 experience sliding friction. Due to the high smoothness of the lower belt circular guide rail 204, this friction will not affect the overall movement of the conveyor belt.

[0069] In some embodiments, the lower conveyor belt assembly 2 further includes a lower belt support plate 203, which is connected to the frame 1 and is used to support the portion of the lower drive belt 201 located above the lower belt drive driven roller 202.

[0070] In some embodiments, the first transmission component of the lower conveyor belt assembly 2 further includes a tensioning member capable of adjusting the distance between the driven roller 202 of the lower belt drive and the driving roller 205 of the lower belt drive in the material transmission direction, thereby adjusting the tension of the lower transmission belt 201.

[0071] Furthermore, the powertrain 7 includes a motor 702, which is connected to the first transmission assembly 4 and the second transmission assembly 5. In some possible embodiments, the first transmission assembly 4 further includes a ratchet pulley 401 connected to the first drive shaft 402 (i.e., the first transmission assembly 4 includes two ratchet pulleys 401); one end of the support shaft 506 (described below) connected to the right eccentric wheel 501 is keyed to a first pulley 504 and a second pulley 505, and the other end of the support shaft 506 connected to the left eccentric wheel 508 is connected to a third pulley 507. The output end of the motor 702 is connected to a fourth pulley 704; the fourth pulley 704 is connected to the first pulley 504 via a first belt 705. The second pulley 505 is connected to one ratchet pulley 401 via a second belt 15, and the third pulley 507 is connected to another ratchet pulley 401 via a third belt 16. Specifically, in this embodiment, a single motor 702 is used to coordinate the reciprocating oscillation of the cutter 901 with the stepping motion of the pressing belt 801 and the lower transmission belt 201, achieving fully mechanized linkage. This saves on control system costs while improving the stability of the movement of each component. The motor 702 provides power to the entire device, and its speed can be adjusted to regulate the slicing speed.

[0072] This application enables adjustable cutting thickness, adjustable speed, and replaceable cutting tools, allowing for the cutting of various materials (slices or segments).

[0073] In some embodiments, the powertrain 7 includes a motor bracket 701 and an adjusting nut 703. The motor bracket 701 connects the motor 702 and the frame 1, and the adjusting nut 703 is connected to the frame 1 and threaded onto one side of the motor bracket 701. Specifically, in this embodiment, the position of the motor 702 connected to the cable bracket relative to the frame 1 can be adjusted by adjusting the length of the adjusting nut 703 screwed into the motor bracket 701, thereby achieving the tension adjustment of the first belt 705.

[0074] In some embodiments, this application further includes a belt tensioning assembly 6, which includes a mounting block 601, a first tensioning pulley 602, a tensioning bolt 603, and a first tensioning pulley shaft 604. The mounting block 601 is connected to the frame 1 and has a vertically extending oblong hole; the mounting block 601 also has a threaded hole extending from top to bottom, communicating with the oblong hole; the first tensioning pulley 602 is rotatably connected to one end of the first tensioning pulley shaft 604, and the other end of the first tensioning pulley shaft 604 passes through the oblong hole and connects to the mounting block 601, and the first tensioning pulley shaft 604 has a threaded hole; the tensioning bolt 603 connects to the threaded hole of the mounting block 601 and the threaded hole of the first tensioning pulley shaft 604. Two belt tensioning assemblies 6 are used, one of which is used to tension a second belt 15. The second belt 15 is wound around a second pulley 505, a ratchet drive pulley 401, and the first tensioning pulley 602 of the belt tensioning assembly 6. Another belt tensioning assembly 6 is used to tension the third belt 16, which is wound around the third pulley 507, another ratchet drive pulley 401, and the first tensioning pulley 602 of the belt tensioning assembly 6. Specifically, in this embodiment, the height of the first tensioning pulley 602 is adjusted by adjusting the position of the first tensioning pulley shaft 604 in the oblong hole, thereby further adjusting the tension of the second belt 15 and the third belt 16.

[0075] In some embodiments, this application further includes a fourth belt 17 and a second tensioning pulley 12 connected to the frame 1. The pressing assembly 8 also includes a pressing pulley 813, which is connected to the pressing drive roller 802. The lower conveyor belt assembly 2 also includes a fifth pulley 207, which is connected to the lower belt drive drive roller 205. The fourth belt 17 is wound around the pressing pulley 813, the fifth pulley 207, and the second tensioning pulley 12. The tension of the fourth belt 17 is adjusted by adjusting the position of the second tensioning pulley 12 on the frame 1. The pressing pulley 813 rotates clockwise, and the fifth pulley 207 rotates counterclockwise, so that the lower surface of the pressing belt 801 moves in the same direction as the upper surface of the lower drive belt 201. Thus, while the pressing drive roller 802 is driven to rotate by the forward ratchet 812 or the backward ratchet 811, it also drives the lower belt drive drive roller 205 to rotate, thereby achieving synchronous movement between the lower drive belt 201 and the pressing belt 801. The structure is stable and reliable.

[0076] In some embodiments, this application further includes two guide assemblies 3 arranged opposite to each other along the width direction of the lower drive belt 201. The guide assemblies 3 are located above the lower drive belt 201 and include guide members and connectors for connecting the guide members to the frame 1. For example, both ends of the connector are respectively connected to the guide members and the frame 1 by screws. In some embodiments, the distance between the guide members of the two guide assemblies 3 can be adjusted. For example, one end of the connector is provided with multiple connection holes, and the connector is connected to the frame 1 through different connection holes, thereby realizing that the distance between the guide members of the two guide assemblies 3 can be adjusted. Specifically, this embodiment guides materials during material transmission. By adjusting the distance between the two guide members, materials of different sizes can be guided.

[0077] In some embodiments, the pressing assembly 8 further includes a brush 814 disposed in front of the pressing belt 801, with both ends of the brush 814 respectively mounted on the pressing side mounting plate 807 by screws; the brush 814 contacts the outer surface of the pressing belt 801. Specifically, the brush 814 can clean the pressing belt 801 when material adheres to it.

[0078] Furthermore, the distance between the pressing assembly 8 and the lower drive belt 201 is adjustable, thus enabling the transport of materials of different thicknesses.

[0079] In some embodiments, the pressing assembly 8 further includes two tension springs 815, which are correspondingly arranged with the pressing side mounting plate 807. One end of the tension spring 815 is connected to the rear end of the pressing side mounting plate 807, and the other end is suspended on the frame 1. Specifically, the rear end of the pressing assembly 8 is connected to the pressing side mounting plate 807 and the frame 1 through the tension spring 815, so that the entire pressing assembly 8 has a certain floating effect, which can better perform pressing.

[0080] In some embodiments, the second transmission assembly further includes a pressing roller 805, which is rotatably connected to the frame 1 and located between the pressing belt circular guide rail 804 and the pressing adjustment roller 806. Thus, at the position between the pressing belt circular guide rail 804 and the pressing adjustment roller 806, the pressing belt 801 forms a portion parallel to the upper portion of the lower transmission belt 201, thereby pressing the material while simultaneously conveying it through this portion and the upper portion of the lower transmission belt 201.

[0081] Furthermore, there are two second transmission assemblies 5, symmetrically arranged on both sides of the cutter assembly 9. Each second transmission assembly 5 includes an eccentric wheel, a second connecting rod 503, a third joint bearing 509, and a fourth joint bearing 510. The eccentric wheel is rotatably connected to the frame 1 via an eccentric wheel bearing seat 502 and a bearing; the eccentric wheels of the two second transmission assemblies 5 (the right eccentric wheel 501 and the left eccentric wheel 508, respectively) are coaxially connected via a support shaft 506; one end of the second connecting rod 503 is connected to one side of the eccentric wheel via the third joint bearing 509, and the eccentric distance of the second connecting rod 503 on the eccentric wheel is adjustable; the other end of the second connecting rod 503 is connected to the cutter transmission shaft 906 via the fourth joint bearing 510. Specifically, in this embodiment, the rotation of the eccentric wheel is transmitted to the cutter assembly 9 via the second connecting rod 503, and the rotation of the eccentric wheel drives the cutter assembly 9 to swing along a swing trajectory. In addition, by adjusting the eccentric distance on the eccentric wheel via the second link 503, the swing angle of the cutter assembly 9 can be adjusted, thereby further adapting to the applicable scenarios of different cutters 901 (because different cutters 901 have different cutting strokes during cutting).

[0082] In some embodiments, the eccentric wheel has multiple circular holes along its circumference, and the distances of the multiple circular holes from the center of the eccentric wheel are different. Thus, the eccentricity of the second connecting rod 503 can be adjusted by connecting it to different circular holes, resulting in a simple structure.

[0083] In some embodiments, the two ends of the second link 503 (i.e. the ends connected to the third joint bearing 509 and the fourth joint bearing 510) are provided with positive and negative threads, thereby facilitating quick adjustment of the length of the second link 503 and thus adjusting the swing angle of the tool holder 902.

[0084] See Figures 10-13 The relative positions of each component after one revolution of motor 702 are as follows:

[0085] See Figure 10 (i.e., in position 1), the forward ratchet 812 is at its highest point, and the center of the first connecting rod 408 and the eccentric adjustable wheel 404 are aligned. The eccentric adjustable wheel 404 rotates clockwise, causing the forward ratchet 812 to rotate clockwise, which in turn drives the pressure belt 801 and the lower drive belt 201. To avoid interference between the cutter 901 and the material, the cutter 901 is in a return state, that is, the cutter 901 swings above the lower drive belt 201 and is in an upward trend. The right eccentric wheel 501 and the right second connecting rod 503 are in the middle position and are in a trend towards the top. At this time, the material moves forward on the lower drive belt 201, and the cutter 901 moves upward.

[0086] See Figure 11(i.e., at position 2), the forward ratchet 812 is at the middle point, the cutter 901 swings to the highest point, and then the eccentric adjustable wheel 404 rotates clockwise to drive the forward ratchet 812 to move clockwise, so that the pressure belt 801 and the lower drive belt 201 move forward. At this time, the cutter 901 begins to move downward.

[0087] See Figure 12 (i.e., at position 3), the forward ratchet 812 is at its lowest point, and the material travels a distance so that it extends a certain distance beyond the lower drive belt 201 to await cutting. At this time, the cutter 901 swings to the middle position and is above the lower drive belt 201 but has not yet cut the material. Then the cutter 901 continues to swing downwards to cut, at which time the forward ratchet 812 rotates counterclockwise, and the pressure belt 801 and the lower drive belt 201 are in a stationary state.

[0088] See Figure 13 (i.e., at position 4), the forward ratchet 812 rotates counterclockwise to the middle position. At this time, the cutter 901 has finished cutting the material and has swung to its lowest point. The forward ratchet 812 rotates counterclockwise, while the pressure belt 801 and the lower drive belt 201 remain stationary. At this time, the reverse ratchet 811 rotates counterclockwise. The cutter 901 swings upward from its lowest point.

[0089] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
