[0004] Another technical problem to be solved by the present invention is to provide a sealing and cutting device.

[0005] Another technical problem to be solved by the present invention is to provide a processing method using the sealing and cutting equipment.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

The rotating column is located at the top of the pressure plate and is connected to the sealing turntable.

[0014] Each of the sealing turntables has a first movable hole at a position corresponding to the rotating column of each of the extrusion sections. The rotating column passes through the first movable hole and can move within the first movable hole.

[0015] The sealing turntable can drive the track column to move within the sealing track via the rotating column. The equilateral triangular plates of the multiple extrusion sections continuously contract or expand as the sealing turntable rotates to adjust the size of the contraction hole.

[0016] A preferred embodiment also includes a rotating power unit. The outer edge of the sealing turntable is provided with multiple serrations. A gear is installed on the power output end of the rotating power unit. The gear meshes with the sealing turntable. The forward or reverse rotation of the rotating power unit can drive the sealing turntable to rotate clockwise or counterclockwise around the first central hole.

[0017] A sealing and cutting device includes a sealing device, a cutting device, and a conveying device;

[0018] The conveying device is located upstream of the sealing device and continuously conveys the strip material along a first direction, which is parallel to the axial direction of the strip material.

[0019] The sealing device is reciprocating along the second direction to compress and heat-melt the strip material to form a heat-sealed part of a set thickness, wherein the second direction is perpendicular to the axial direction of the strip material;

[0020] The cutting device is located downstream of the sealing device and can reciprocate along the second direction to cut the heat-sealed portion.

[0021] The conveying device conveys the strip material along the first direction to the sealing device for heat sealing to form a heat-sealed part; and continues to convey the strip material to the cutting device so that the heat-sealed part corresponds to the cutting device, thereby completing the cutting of the strip material.

[0022] Preferably, the sealing device includes: a sealing base, an extrusion section, and a sealing turntable. The sealing base is fixedly installed, and a first central hole is formed at the center of the sealing base. Multiple extrusion sections are rotatably mounted on the top of the sealing base, with one end of each extrusion section extending into the first central hole, so that the ends of the multiple extrusion sections extending into the first central hole together form a contraction hole. The sealing turntable is rotatably mounted on the extrusion sections around the axis of the first central hole, and each extrusion section is connected to the sealing turntable. The sealing turntable drives the multiple extrusion sections to rotate together, continuously contracting or expanding the contraction hole.

[0023] The cutting device includes: a cutting base, cutting sections, and a cutting turntable; the cutting base is fixedly disposed below the sealing base, and a second central hole is formed in the center of the cutting base, the central axis of the second central hole coinciding with the central axis of the first central hole; there are multiple cutting sections, each of which is movably mounted on the top of the sealing base, and each cutting section includes a cutting blade located in the second central hole; the cutting turntable is rotatably disposed on the cutting sections around the axis of the second central hole, and each cutting section is connected to the cutting turntable, the cutting turntable drives the multiple cutting sections to rotate together, so that the cutting blades of the multiple cutting sections squeeze or separate from each other to complete the cutting.

[0024] Preferably, the top of the cutting chassis is provided with a cutting track surrounding the second central hole;

[0025] The cutting section includes a cutting plate, a cutting blade, a movable column, and a positioning column. The cutting blade is a column disposed on the top of the cutting plate, and the cross-section of the cutting blade is fan-shaped. The movable column is disposed on the top of the cutting plate and is parallel to the cutting blade. The positioning column is disposed on the bottom of the cutting plate and is located within the cutting track. The positioning column is capable of rotating within the cutting track.

[0026] A second movable hole is provided at the position corresponding to the movable column of each cutting part on the cutting turntable. The movable column passes through the second movable hole and can move within the second movable hole.

[0027] The cutting turntable can drive the positioning column to move within the cutting track via the movable column. The cutting blades of the multiple cutting parts are continuously squeezed or separated as the cutting turntable rotates to complete the cutting.

[0028] Preferably, the device further includes an adjustment device comprising a movable base, a limiting seat, and a limiting member. The movable base is movably disposed on one side of the sealing device. The bottom of the limiting seat is fixed to the movable base. The first end of the limiting member is detachably connected to the limiting seat. The second end of the limiting member has at least one limiting hole, and the axis of the limiting hole is parallel to the axis of the first central hole. The movable base can drive the limiting seat to move, thereby adjusting the axis of the limiting hole to coincide with the axis of the first central hole.

[0029] Preferably, the second end of the limiting member is provided with a plurality of limiting holes, and the diameter of each limiting hole is different.

[0030] A processing method using the aforementioned sealing and cutting equipment includes the following steps:

[0031] The material to be processed is conveyed to the sealing device along the axial direction of the material to be processed using a conveying device.

[0032] A sealing device is used to compress and seal the material to be processed along the radial direction, forming a heat-sealed section of a set thickness.

[0033] The sealed material to be processed is continued to be conveyed to the cutting device using a conveying device, so that the heat-sealed part corresponds to the cutting device;

[0034] The heat-sealed portion of the material to be processed is cut off by extrusion along the radial direction of the material to be processed using a cutting device.

[0035] The present invention has the following technical advantages: In practical use, the sealing and cutting equipment of the present invention first uses a conveying device to transport the material into the shrinkage orifice of the sealing device. Then, the sealing turntable drives each extrusion section to continuously shrink, thereby making the shrinkage orifice smaller and finally completing the sealing. After sealing, each extrusion section expands to its initial position, and then the conveying device transports the material to the cutting device, which cuts off the sealed portion of the material, thus completing the entire operation. This sealing and cutting equipment is very convenient to use and can quickly complete the sealing and cutting operations of materials. Simultaneously, because the conveying device can continuously transport materials, the sealing and cutting devices also continuously perform sealing and cutting operations, forming a continuous and uninterrupted working mode, thereby improving work efficiency and overall performance.

[0063] The technical content of the present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0064] Example 1:

[0065] Reference Figure 1 and Figure 2As shown, a sealing and cutting device according to an embodiment of the present invention includes: a sealing device 10, a cutting device 20, and a conveying device (not shown in the figure). The conveying device is used to convey a long, thin material 60, the sealing device 10 is used to seal the material 60, and the cutting device 20 is used to cut the sealed material 60. The conveying device is located upstream of the sealing device 10, and the cutting device 20 is located downstream of the sealing device 10. The conveying device conveys the material along a first direction, sequentially passing it through the sealing device 10 and the cutting device 20, to first seal the material 60 and then cut it. In this embodiment, the material is a long, thin tube made of polylactic acid (PLA), but it can also be other resin materials or medical materials.

[0066] Reference Figure 6B and Figure 6C As shown, in this embodiment, the first direction is the forward direction of the material 60. Correspondingly, the sealing device 10 can reciprocate in a plane perpendicular to the first direction (i.e., the first vertical plane A) to compress and simultaneously heat-melt the strip-shaped material 60 to form a heat-sealed portion 610 of a set thickness. Simultaneously, the cutting device 20 can reciprocate in a plane perpendicular to the first direction (i.e., the second vertical plane B) to cut the heat-sealed portion 610. The distance H between the sealing surface of the sealing device 10 (also the first vertical plane A) and the cutting surface of the cutting device 20 (also the second vertical plane B) is the length of a radioactive particle.

[0067] Specifically, the conveying device first transports the strip material 60 along a first direction to the sealing device 10, where it is heat-sealed to form a heat-sealed section. The conveying device then continues to transport the strip material 60 to the cutting device 20, ensuring that the heat-sealed section corresponds to the cutting device 20 (i.e., the cutting surface of the cutting device 20 should be located within the heat-sealed section). The cutting device 20 cuts the heat-sealed section in a second vertical plane, thus completing the cutting of one radioactive particle. After one radioactive particle is cut, the conveying device continues to transport the material for the next radioactive particle cutting operation, thus forming a continuous cutting working mode to improve production efficiency.

[0068] Specifically, refer to Figures 3 to 7 As shown, the sealing device 10 includes: a sealing base plate 1, a pressing section 2, and a sealing turntable 3. The sealing base plate 1 is a frustum of a cone, as shown in the figure. Figure 1 and Figure 2 As shown, the sealing base 1 is mounted on top of multiple first columns 30, thereby utilizing the first columns 30 to provide support for the sealing base 1. A first central hole 11 is provided in the center of the sealing base 1. (Refer to...) Figure 4As shown, there are multiple extrusion sections 2, each rotatably mounted on the top of the sealing base 1, with one end of each extrusion section 2 extending into the first central hole 11. This allows the ends of the multiple extrusion sections 2 extending into the first central hole to collectively form a shrinkage hole 101. A sealing turntable 3 is rotatably mounted on the extrusion sections 2 around the axis of the first central hole 11, and each extrusion section 2 is connected to the sealing turntable 3. The sealing turntable 3 drives the multiple extrusion sections 2 to rotate together (the extrusion sections actually move horizontally along the grooves in the base 1), continuously shrinking or expanding the shrinkage hole 101. Specifically, after the conveying device delivers the material to the sealing device 10, the material enters the shrinkage hole 101. By rotating the sealing turntable 3, multiple extrusion sections 2 rotate together, causing the shrinkage hole 101 to continuously shrink, thus completing the sealing operation of the material. After sealing is completed, the sealing turntable 3 rotates in the opposite direction, causing multiple extrusion sections 2 to rotate together, thereby expanding the shrinkage hole 101 to its initial position, ready for the next sealing operation. It is easy to understand that the thickness of the extrusion section 2 itself is the thickness of the heat-sealed section formed after the material is heat-melted and sealed, and the thickness of the extrusion section 2 can be adaptively selected according to needs.

[0069] Reference Figure 5 As shown in the above embodiment, a sealing track 12 is provided around the first central hole 11 on the top of the sealing base 1. The sealing track 12 is a regular hexagonal annular groove structure. The sealing track 12 divides the sealing base 1 into an inner sealing plate 13 and an outer sealing plate 14. The first central hole 11 is located at the center of the inner sealing plate 13. Multiple sealing base mounting holes 15 are provided on the outer sealing plate 14. The sealing base 1 can be fixed to the top of multiple first columns 30 using these sealing base mounting holes 15 to fix the relative position of the sealing base 1. At the same time, the size of the first central hole 11 can be determined as needed. While allowing materials to pass through, it can also reduce the weight of the sealing base 1.

[0070] Reference Figure 4 and Figure 6A As shown, there are six extrusion sections 2, each including a pressure plate 21, a track column 22, and a rotating column 23. The pressure plate 21 consists of a rectangular plate 211 and an equilateral triangular plate 212. One side of the equilateral triangular plate 212 shares a side with the long side of the rectangular plate 211. (Referring to...) Figure 3 and Figure 4As shown, six equilateral triangular plates 212 extend into the first central hole 11, forming an equal hexagonal contraction hole 101. A track post 22 is located at the bottom of the rectangular plate 211 of the pressure plate 21. The track post 22 is a cuboid-shaped protrusion, the width of which should match the width of the sealing track 12, allowing the track post 22 to enter and rotate within the sealing track. It is understood that the cuboid-shaped protrusion of the track post 22 is designed so that its two sides abut against the two opposing inner walls of the sealing track 12, thus limiting its movement and preventing the pressure plate 21 from rotating irregularly. A rotating post 23 is located at the top of the rectangular plate 211; it is a cylinder and is used to connect with the sealing turntable 3 to transmit power.

[0071] Reference Figure 7 As shown, the sealing turntable 3 is a circular disc-shaped structure with a sealing working hole 31 in its center for material passage and to reduce the weight of the sealing turntable 3. Six first movable holes 32 are provided on the sealing turntable 3 at positions corresponding to the rotating columns 23 of each extrusion section 2. These six first movable holes 32 are elongated and evenly distributed clockwise, so that the extensions of their center lines combine to form a regular hexagon. The rotating columns 23 pass through and can move within the first movable holes 32, thus achieving a transmission connection with the sealing turntable 3.

[0072] In actual operation, after the conveying device delivers the material into the shrinkage hole 101, the sealing turntable 3 starts to rotate in the forward direction, thereby driving the rotating column 23 to move within the first movable hole 32, and then driving the track column 22 to move within the sealing track 12. As the track column 22 moves within the sealing track 12, the equilateral triangle plates 212 of the multiple extrusion parts 2 continuously shrink, thereby making the shrinkage hole 101 continuously smaller, and finally completing the sealing. After the sealing is completed, the sealing turntable 3 starts to rotate in the reverse direction, thereby driving the equilateral triangle plates 212 of the six extrusion parts 2 to continuously expand, so that the shrinkage hole 101 returns to its initial state, ready for the next sealing operation.

[0073] In the above embodiment, the sealing device 10 further includes a heating section (the base 1 is also a heating plate, heating rods are inserted into the side holes of the heating plate, and temperature sensors are threaded into the side holes of the base 1). The heating section can be multiple heating rods, a heating plate, or a layer of heating wire, etc. The heating section is located at the bottom of the sealing base 1. Both the sealing base 1 and the multiple extrusion sections 2 are made of heat-conducting materials (e.g., copper, iron, etc.). When the heating section starts heating, heat is conducted through the sealing base 1 to the multiple extrusion sections 2, causing the equilateral triangular plates 212 of the multiple extrusion sections 2 to reach a set temperature. When sealing the material, the extrusion heating and melting method ensures the sealing performance of the material after sealing, thereby improving the sealing effect.

[0074] In the above embodiments, the sealing device 10 further includes a rotating power unit (not shown in the figure) for providing power. Preferably, the rotating power unit is a rotary cylinder, and a gear is installed on the power output end of the rotary cylinder. At the same time, multiple serrations (not shown in the figure) are provided on the outer edge of the sealing turntable 3. By meshing the gear with the sealing turntable 3, the rotation of the rotary cylinder can drive the sealing turntable 3 to rotate clockwise or counterclockwise around the first central hole.

[0075] Reference Figures 8 to 13 As shown, the cutting device 20 includes: a cutting base 4, a cutting section 5, and a cutting turntable 6. The cutting base 4 is a frustum of a cone, as shown in the figure. Figure 1 and Figure 2 As shown, the cutting base 4 is assumed to be on top of multiple second columns 40, thereby using the second columns 40 to provide support for the cutting base 4. A second central hole 41 is provided in the center of the cutting base 4, and the central axis of the second central hole 41 coincides with the central axis of the first central hole 11. (Refer to...) Figure 9 As shown, there are multiple cutting sections 5, each movably mounted on the top of the sealing base 1. Each cutting section 5 includes a cutting blade 51 located within the second central hole 41, enabling cutting operations to be performed using the cutting blades 51 of multiple cutting sections 5. A cutting turntable 6 is rotatably mounted on the cutting sections 5 around the axis of the second central hole 41, and each cutting section 5 is connected to the cutting turntable 6. The cutting turntable 6 drives the multiple cutting sections 5 to rotate together, causing the cutting blades 51 of the multiple cutting sections 5 to press against or separate from each other, thus completing the cutting.

[0076] Specifically, after the material is sealed, the conveying device continues to convey the material to the cutting device 20. The sealed material enters the cutting holes 201 formed by the cutting blades 51 of the multiple cutting sections 5. By rotating the cutting turntable 6, the multiple cutting sections 5 rotate together, causing the multiple cutting blades 51 to squeeze against each other, thereby completing the cutting operation of the material. The cut material will fall naturally, and a collection box can be placed under the cutting base 4 to collect the cut material. After the material is cut, the cutting turntable 6 rotates in the opposite direction, causing the cutting blades 51 of the multiple cutting sections 5 to separate from each other, forming cutting holes 201 again, ready for the next cutting operation.

[0077] Reference Figure 10 As shown in the above embodiment, a cutting track 42 is provided around the second central hole 41 on the top of the cutting base 4. The cutting track 42 is an equilateral triangular annular groove structure, which divides the cutting base 4 into an inner cutting plate 43 and an outer cutting plate 44. The second central hole 41 is located at the center of the inner cutting plate 43, and multiple cutting base mounting holes 45 are provided on the outer cutting plate 44. The cutting base 4 can be fixed to the top of multiple second columns 40 using these mounting holes 45 to fix the relative position of the cutting base 4. At the same time, the height of the second columns 40 is lower than the height of the first column 30, so that the cutting base 4 is located below the sealing base 1. In addition, the size of the second central hole 41 can be determined as needed, which can reduce the weight of the cutting base 4 while allowing materials to pass through.

[0078] Reference Figure 11 and Figure 12 As shown, the cutting section 5 includes a cutting blade 51, a cutting plate 52, a movable column 53, and a positioning column 54. The cutting plate 52 is approximately a triangular plate with a 120° apex angle. A notch 521 is formed on the side opposite the apex angle of the triangular plate, the size of which corresponds to the size of the cutting base mounting hole 45 on the cutting base 4. The cutting blade 51 is a column located on top of the cutting plate 52, and its cross-section is fan-shaped with a 120° apex angle. The cutting blade 51 is positioned at the apex angle of the cutting plate 52, so that its two inclined surfaces are coplanar with the two inclined surfaces at the apex angle of the cutting plate 52. The movable column 53 is located on top of the cutting plate 52 and parallel to the cutting blade 51. The movable column 53 is a cylinder used to connect with the cutting turntable 6 to transmit power. The positioning post 54 is disposed at the bottom of the cutting plate 52 and located within the cutting track 42. The positioning post 54 can rotate within the cutting track 42. Preferably, the positioning post 54 is cuboid in shape, and the width of the cuboid positioning post 54 matches the width of the cutting track 42, thereby limiting the cutting plate 52.

[0079] Reference Figure 13 As shown, the cutting turntable 6 is a circular disc structure with a cutting working hole 61 in its center for material passage and to reduce the weight of the cutting turntable. Simultaneously, three elongated second movable holes 62 are provided on the cutting turntable 6 at positions corresponding to the movable columns 53 of each cutting section 5. These three holes 62 are evenly distributed clockwise, and the extensions of their center lines form an equilateral triangle. The movable columns 53 pass through and can move within the second movable holes 62, thus achieving a transmission connection with the cutting turntable 6.

[0080] In actual operation, after the conveying device delivers the sealed material into the cutting hole 201, the cutting turntable 6 starts to rotate in the forward direction, thereby driving the movable column 53 to move in the second movable hole 62, and then driving the positioning column 54 to move in the cutting track 42. The cutting blades 51 of the multiple cutting parts 5 continuously squeeze as the cutting turntable rotates, thereby cutting the material. After the material is cut off, the cutting turntable 6 starts to rotate in the reverse direction, thereby driving the three cutting blades 51 to separate from each other, so that the cutting hole 201 returns to its initial state, ready for the next cutting operation.

[0081] Furthermore, in the above embodiments, the cutting device 20 also includes a rotating power unit, the structure of which is the same as that of the sealing device 10, and will not be described again here. Of course, in other embodiments, the specific structure of the rotating power unit can also be adapted as needed.

[0082] Example 2:

[0083] Based on Example 1, continue to refer to Figure 1 and Figure 2 As shown, the sealing and cutting equipment also includes an adjustment device 50, which includes a movable base 7, a limiting seat 8, and a limiting member 9. The movable base 7 is used for position adjustment, the limiting seat 8 provides an installation base for the limiting member 9, and the limiting member 9 is used to limit the position of the material.

[0084] Specifically, in this embodiment, the movable base 7 is a commercially available dual-axis movable module, as shown in the reference. Figure 1 As shown in the coordinate system, the conveying device transports the material along the Z-axis, while the movable base 7 is located on one side of the sealing device 10 (which can be...). Figure 1 The movable base 7 can be moved along the X and Y directions (from left to right, front to back, etc.) to adjust its position in the horizontal plane. It is understood that if the conveying device conveys material along the X direction, the dual-axis moving module will adjust its position along the Y and Z directions.

[0085] Reference Figure 14 As shown, the limiting seat 8 is U-shaped, and the opening of the U-shaped limiting seat 8 is horizontal. The bottom of the limiting seat 8 is provided with a first connecting hole 81, and the top of the limiting seat 8 is provided with a second connecting hole 82. The first connecting hole 81 is used to connect with the movable base 7, thereby limiting the relative position of the movable base 7 and the limiting seat 8 (which can be connected by bolts). The second connecting hole 82 is used to detachably connect with the limiting member 9.

[0086] Reference Figure 15 As shown, the limiting member 9 is a rectangular connecting plate. A third connecting hole 91 is provided at the first end of the limiting member 9. A connecting component (e.g., a bolt) can pass through the second connecting hole 82 and the third connecting hole 91 in sequence, thereby bolting the limiting member 9 to the top of the limiting seat 8, achieving a detachable connection between the limiting seat 8 and the limiting member 9. Simultaneously, at least one limiting hole 92 is provided at the second end of the limiting member 9, as shown in the figure. Figure 1 In the coordinate system shown, the axis of the limiting hole 92 is parallel to the axis of the first central hole 11. By adjusting the position of the dual-axis moving module, the axis of the limiting hole can be made to coincide with the axis of the first central hole. At this time, the material will first pass through the limiting hole 92 and then enter the sealing device 10. Thus, the limiting hole 92 can be used to limit the material, thereby ensuring the stability of the material during the conveying process. It is understood that the diameter of the limiting hole 92 should match the size of the material to be processed. In this embodiment, the material to be processed is a particle tube with an inner diameter of 0.6 mm and an outer diameter of 0.8 mm, which is made of biodegradable material.

[0087] Reference Figure 16 and Figure 17 As shown, in another embodiment, the limiting member 9 is a cuboid structure with a through oblong hole in the middle. The bolt can pass through the oblong hole and be threaded to the round hole on the device below. The limiting position can be adjusted through the oblong hole structure on the limiting member 9.

[0088] In the above embodiments, in order to improve the applicability of the sealing and cutting equipment, multiple limiting holes 92 can be opened at the second end of the limiting member 9, and the diameter of each limiting hole 92 is different. Thus, limiting holes 92 with different diameters can be selected to match different materials.

[0089] Example 3:

[0090] Reference Figures 18 to 21 As shown, this is another sealing and cutting device provided by an embodiment of the present invention, which includes a sealing device 10', a cutting device 20' and a conveying device 70. The difference between this embodiment and the first embodiment is that the cutting device 20' and the conveying device 70 are different in this embodiment. The differences will be described in detail below.

[0091] Reference Figure 19 As shown, in this embodiment, the cutting device 20' includes a cutting base 4', a positioning part 5', a cutting part 6', a power part 7', and a transmission part 8'. The cutting base 4' is a disc, and the center of the disc 4' is along the axial direction (i.e., Figure 18 The cutting base plate 4' has a working hole 41' in the vertical direction for material to pass through. The material guiding device 60' is located above the cutting base plate 4' and has a guide hole 601'. The material passes through the guide hole 601' and is guided by the material guiding device 60'.

[0092] The positioning part 5' consists of two sector plates, which are stacked one on top of the cutting base 4', with a gap between them for the cutting blade to pass through.

[0093] The cutting part 6' is elongated and is rotatably mounted on the top of the cutting base 4'. The cutting part 6' and the positioning part 5' are located on opposite sides of the working hole 41'. The side of the cutting part 6' closest to the working hole 41' has an arc-shaped notch, and a cutting blade 61' is provided in the arc-shaped notch. The thickness of the cutting blade 61' corresponds to the gap between the two fan-shaped plates.

[0094] The power unit 7' is a rotary motor or a rotary cylinder; in this embodiment, it is a rotary cylinder. The power unit 7' is located below the cutting chassis 4'. The power output end of the power unit 7' is connected to the cutting section 6' via a transmission unit 8', thereby enabling the power unit 8' to drive the cutting section 6' to rotate within the top plane of the cutting chassis 4' (rotation direction as shown). Figure 18 (As shown by the middle arrow), thereby using the cutting blade 61' to cut the material 60.

[0095] Reference Figure 20 As shown, the transmission unit 8' includes a turntable 81', a transmission rod 82', and a guide rod 83'. The turntable 81' is horizontally mounted on the power shaft of the rotary cylinder. The transmission rod 82' is vertically mounted on the turntable 81'. The guide rod 83' is horizontally positioned and has a guide hole 831'. The transmission rod 82' passes through the guide hole 831'. The cutting part 6' is horizontally mounted on the guide rod 83'. Thus, the rotary cylinder 6' drives the turntable 81' to rotate, which in turn drives the transmission rod 82' to rotate. The transmission rod 82' moves within the guide hole 831', thereby causing the cutting part 6' mounted on the guide rod 83' to rotate within the top plane of the cutting base 4' to cut the material.

[0096] Meanwhile, it should be understood that in this embodiment, the rotary cylinder is a reciprocating cylinder. After the cylinder completes the rotary cutting by rotating once in the forward direction, the cylinder will reverse, so that each component returns to its initial position to await the next cutting operation.

[0097] Reference Figure 21 As shown, in this embodiment, the conveying device 70 specifically includes a stepper motor 701, a stepper wheel 702, and a guide wheel 703. The stepper motor 701 is mounted on the conveying bracket 704, the stepper wheel 702 is mounted on the power output end of the stepper motor 701, and the guide wheel 703 is rotatably mounted on the conveying bracket 704. The guide wheel 703 is arranged adjacent to the stepper wheel 702, and a guide groove 705 is formed on the outer edge of the guide wheel 703. The width of the guide groove 705 matches the diameter of the material.

[0098] During actual feeding, the material passes through the guide groove 705. The stepper motor 701 drives the stepper wheel 702 to advance a set distance (this distance can be set as needed, such as 1cm, 2cm, 3cm, etc.). Then, the stepper wheel 702 compresses the material and moves it the set distance, completing the feeding process. Thus, the guide groove 705 guides and limits the material, preventing deviation during feeding and improving feeding stability.

[0099] Except for the structure described above, the rest of the structure in this embodiment is the same as in Embodiment 1, and will not be repeated here.

[0100] The quantities or specific values ​​mentioned above are for ease of understanding only and do not constitute a limitation of the present invention. The present invention has been described in detail above. Any obvious modifications made by those skilled in the art without departing from the essential content of the present invention will constitute an infringement of the patent rights of the present invention and will incur corresponding legal liability.
