Description

Technical Field

[0001] The present invention relates to the technical field of handbag manufacturing equipment, and specifically to a handbag manufacturing equipment. Background Art

[0002] In the development process of the handbag manufacturing industry, the existing technologies face many problems that need to be solved urgently, which seriously restrict the improvement of production efficiency, cost control, and product quality.

[0003] In terms of the processing flow, traditional handbag manufacturing equipment uses the method of punching and blanking separation. After punching, it is necessary to use an independent waste cleaning device or manual labor to clean up the waste materials. This not only greatly prolongs the processing cycle, but also the problem of waste material accumulation seriously affects the cleanliness of the production site and the progress of subsequent processes. In addition, the additional waste cleaning device increases the equipment cost and maintenance cost, while manual cleaning is inefficient and prone to incomplete cleaning.

[0004] In terms of tool replacement, the punch of traditional equipment is usually of an integral structure. When different-shaped handbags need to be produced, replacing the punch as a whole not only takes a long time, resulting in an increase in downtime, but also has a high replacement cost. This makes it difficult for enterprises to respond quickly when facing diverse customized production demands, seriously affecting the production flexibility and market competitiveness.

[0005] From the perspective of equipment life, in the punching process of traditional handbag manufacturing equipment, the pressure distribution is unreasonable. Due to the lack of effective pressure balance measures, the surface pressure distribution of the bottom plate is uneven under the action of punching pressure, which is prone to deformation, thereby shortening the service life of key components such as the bottom plate and tools. At the same time, uneven pressure will also lead to inconsistent indentation depths, affecting the finished product quality of the handbag.

[0006] In terms of cutting safety, traditional handbag manufacturing equipment has multiple potential hazards, posing a threat to the safety of operators and production stability. Existing handbag manufacturing equipment cuts up and down by a lifting mechanism during cutting, and its cutting force cannot be adjusted and is much greater than the cutting requirement of the handbag. Because the force is uncontrollable and large, safety problems are likely to occur.

[0007] In summary, the existing handbag manufacturing technologies have obvious deficiencies in multiple aspects such as processing flow, tool replacement, equipment life, and cutting safety. In order to meet the market demand for high-efficiency, low-cost, and high-quality handbag production, there is an urgent need for an innovative handbag manufacturing equipment that can effectively solve the above problems and promote the development and progress of the industry.

[0008] Therefore, a handbag manufacturing equipment is proposed. Summary of the Invention

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The handbag manufacturing equipment described in the present invention realizes integrated punching and blanking processing. Through the elastic pre-pressing of the cardboard by the pressing plate and the precise alignment design of the punching blade and the bottom plate cutting edge groove, after the cutting action is completed, the ejecting component can synchronously push the remaining material through the cutting edge groove onto the conveyor belt, and the cardboard forms a finished handbag after a single punching, eliminating the independent waste removal device or manual cleaning link in the traditional process, significantly shortening the processing cycle and effectively avoiding waste accumulation.

[0034] 2. The handbag manufacturing equipment described in the present invention constructs a modular tool rapid switching system.

The side wall of the pressing plate is provided with a standardized tool mounting groove and is equipped with a quick-release mechanism to realize the rapid replacement of multi-specification tools, reduce downtime and maintenance costs, and at the same time adapt to the customized production requirements of different-shaped handbags.

[0035] 3. The handbag manufacturing equipment described in the present invention optimizes the pressure distribution to extend the equipment life. Through the rigid support of the middle part of the bottom plate by the support plate and the distributed support of the edge of the bottom plate by the support seat, the punching pressure is evenly dispersed, greatly reducing the risk of deformation of the bottom plate, extending the service life of key components, and improving the consistency of the indentation depth.

[0036] 4. The handbag manufacturing equipment described in the present invention relies on the self-gravity of the tool and the gas to drive the piston to descend, ensuring sufficient cutting power for the tool. During the cutting process, the gas pressure and the self-gravity of the tool act together, enabling the tool to quickly and powerfully cut cardboard of different thicknesses and materials. Compared with traditional equipment, the power is more stable and strong, effectively avoiding problems such as incomplete cutting and uneven edges, and improving the cutting quality of the product.

[0037] 5. The handbag manufacturing equipment described in the present invention proposes an innovative safety protection solution for the potential safety hazards and power control defects existing in the cutting operation of traditional equipment. By dynamically adjusting the gas volume at the bottom of the piston, the kinetic energy of the tool during cutting is accurately controlled, so that the cutting force forms a matching relationship with the shear strength of the cardboard: when cutting the cardboard, the stroke of the piston or the kinetic energy of cutting the cardboard can be adjusted by adjusting the volume of the cavity at the bottom of the piston, thereby adjusting the kinetic energy of the punch, that is, the punching blade, for cutting different cardboards. This design method can make the punching blade just cut off the cardboard, neither causing waste of energy nor ensuring the safety of punching. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Please refer to Figures 1 to 5 , the present invention provides a handbag manufacturing device, and the technical solution is as follows:

[0045] A handbag manufacturing device, comprising:

[0046] A base 6, guide posts 3 are fixedly installed at the four corners of the base 6, the interior of the guide posts 3 is a cavity and a cylinder 26 is placed above, the cylinder 26 is connected to a piston 29 through a second telescopic rod 28, a magnet is installed inside the piston 29 and the piston 29 is located in the cavity inside the guide post 3;

[0047] An upper template 1, the upper end of the guide post 3 is slidably installed with an upper template 1, guide sleeves 2 are fixedly installed at the four corners of the upper template 1, the guide sleeves 2 are sleeved on the guide posts 3 and a magnetic outer ring 27 is arranged inside the guide sleeves 2; the magnetic outer ring 27 and the magnet installed inside the piston 29 are magnetically attracted.

[0048] A punch 14, the punch 14 is fixedly installed on the bottom surface of the upper template 1;

[0049] A bottom plate 4, the bottom plate 4 is installed on the base 6, and the bottom plate 4 is used to cooperate with the punch 14 to punch cardboard;

[0050] When it is necessary to lift the upper template 1, the cylinder 26 controls the piston 29 to move upward through the second telescopic rod 28. A negative pressure chamber is formed in the cavity at the bottom of the piston 29. The magnet in the piston 29 attracts the magnetic outer sleeve 27, and the two move upward synchronously. Since the magnetic outer sleeve 27 is arranged in the upper template 1, the upper template 1 is finally lifted; during the return stroke, the cylinder 26 stops working, and at this time the second telescopic rod 28 can move freely. The piston 29 moves downward rapidly under the negative pressure of the bottom sealed cavity, and the outer upper template 1 moves downward rapidly under the action of magnetic force and its own gravity, realizing the cutting of the handbag;

[0051] The space between the cylinder 26 and the cavity at the bottom of the piston 29 is adjustable, and it is ensured that the downward kinetic energy is zero or close to zero after the punching of the punch 14 is completed. When cutting the cardboard, the stroke of the piston 29 or the kinetic energy of cutting the cardboard can be adjusted by adjusting the volume of the cavity at the bottom of the piston 29, so as to adjust the kinetic energy of the punch 14 for cutting different cardboard. This design method can make the punching blade 1402 just cut off the cardboard, which not only does not cause waste of energy, but also ensures the safety of punching. For the convenience of understanding and expression, here the piston 29 and the punch 14 can be understood as a rigid body. When it is necessary to cut thicker or harder cardboard, the punch 14 requires greater kinetic energy. The volume of the cavity at the bottom of the piston 29 can be reduced to reduce the air in the cavity at the bottom of the piston 29, thereby increasing the kinetic energy of the punch 14 when passing through the punching position; on the contrary, when it is necessary to cut thinner or softer cardboard, the punch 14 requires smaller kinetic energy. The volume of the cavity at the bottom of the piston 29 can be increased to increase the air in the cavity at the bottom of the piston 29, thereby reducing the kinetic energy of the punch 14 when passing through the punching position. The above method can realize the just cutting of the cardboard by the punch 14, avoiding the redundant kinetic energy of the upper template 1 hitting the bottom plate 4 and improving the safety.

[0052] The punching position of the punch 14 on the cardboard may be the process of the punch 14 decelerating downward. At this time, the air in the cavity at the bottom of the piston 29 is compressed to decelerate the piston 29, and the piston 29 transfers the resistance to the punch 14 through magnetic force, so that the punch 14 performs punching during deceleration; it may also be the process of the punch 14 accelerating downward first and then decelerating downward. At this time, the air in the cavity at the bottom of the piston 29 is first negatively pressured to attract the piston 29 to move downward, then the air in the cavity at the bottom of the piston 29 returns to normal air pressure, and then the piston 29 squeezes the air in the bottom cavity to form positive pressure to decelerate the punch 14.

[0053] The present invention realizes the adjustment of the punching kinetic energy of the punch 14 by adjusting the air content in the cavity at the bottom of the piston 29, and the adjustment is convenient and fast.

[0054] Trimming component, a trimming component is provided on the bottom surface of the upper template 1, and the trimming component is used for trimming the redundant corners on the cardboard at one time;

[0055] A blanking component, a blanking component is provided on the base 6, and the blanking component is used to clean the cut corners.

[0056] Preferably, the edge cutting component includes:

[0057] A rectangular groove opened in the middle of the upper template 1, and a punching blade 1402 is embedded in the rectangular groove;

[0058] A limit pin 12 slidably passing through a countersunk hole at the top of the upper template 1, and an external thread is provided at its lower end;

[0059] A pressure plate 1401, a connection hole with an internal thread is opened at the top thereof, and it is fixedly connected to the lower end of the limit pin 12 by screwing;

[0060] The pressure plate 1401 is slidably arranged in the rectangular groove, and an indentation copper wire 25 is fixedly installed on its bottom surface, and the protruding height of the indentation copper wire 25 is 0.1 - 0.3 mm higher than the edge of the punching blade 1402, so that the indentation copper wire 25 contacts the cardboard first to make an indentation before punching;

[0061] A pressure spring 13 sleeved around the limit pin 12, and its two ends respectively abut against the bottom surface of the countersunk hole and the top surface of the pressure plate 1401. When the pressure spring 13 is in the natural state, the vertical position of the pressure plate 1401 extends to a position further below the bottom of the punching blade 1402. When punching the cardboard, first press and fix the cardboard through the pressure plate 1401. Through the pressure of the pressure spring 13 on the pressure plate 1401, the indentation copper wire 25 on the bottom surface of the pressure plate 1401 makes a crease on the cardboard. At this time, the pressure plate 1401 is pressed into the rectangular groove, and the cutting blade continues to press down with the upper template 1 to cut off the excess corners of the cardboard at one time.

[0062] Furthermore, a through hole is opened at the top of the punching blade 1402, a threaded hole is opened in the rectangular groove of the upper template 1, a connecting column 24 is rotatably installed in the threaded hole, the connecting column 24 fixes the punching blade 1402 in the rectangular groove opened in the upper template 1, the connecting column 24 is located inside the punching blade 1402, and a top - out component is provided in the connecting column 24, and the top - out component is used to top out the cut corners.

[0063] In existing die-cutting machines, since the indentation copper wire 25 is installed on the punch 14, when the punch 14 cuts the cardboard along with the upper template 1, the crease left by the indentation copper wire 25 on the cardboard may be too deep, affecting subsequent processing. The present invention adopts a spliced blade installation. The traditional punch 14 is split into a pressure plate 1401 and a cutting blade 1402. A fixing ring is fixedly installed on the upper part of the connecting column 24. By rotating the thread at the top of the connecting column 24, the fixing ring fixes the cutting blade 1402 in a rectangular groove inside the upper template 1. During cutting, the upper template 1 drives the cutting blade 1402 to cut the cardboard, and the pressure on the cardboard by the indentation copper wire 25 is provided by the pressure spring 13. When the pressure applied by the upper template 1 is too large, the excess force is converted into elastic potential energy and stored in the deformation of the spring, preventing the die-cutting machine from applying excessive pressure due to improper debugging or malfunction. Moreover, the ejection assembly inside the cutting blade 1402 ejects the remaining material cut, preventing the remaining material from accumulating inside the cutting blade 1402.

[0064] Furthermore, since most of the remaining material to be cut for handbags is located at the edge of the cardboard, the knife-edge groove on the bottom plate 4 can be formulated according to the specifications of handbags with a relatively large production volume. Matching with the tool-loading groove provided on the side wall of the pressure plate 1401, appropriate tools can be loaded into the tool-loading groove according to production needs. When it is necessary to remove a certain cutting blade 1402 for producing another type of handbag, it does not affect subsequent cutting. Compared with the traditional method of cutting with a whole plate, the time and cost of replacing the punch 14 are saved.

[0065] It should be noted that there are many knife-edge grooves provided on the bottom plate 4. If the indentation in some areas pressed by the indentation copper wire 25 on the pressure plate 1401 during production is relatively shallow or there is no indentation, this does not affect the subsequent folding process. The reason is that during subsequent folding, whether it is manual folding or mechanical folding, pressing will be carried out during folding. Therefore, as long as the folding line is greater than half of the required crease, it will not be affected.

[0066] In addition, as a way of the present invention, the cutting blade 1402 can also be in a block shape, with the side edge of the block as the cutting edge. In this way, when cutting the cardboard, it can also cut the remaining material on the cardboard and push it along the knife-edge groove into the conveyor belt 7 below.

[0067] The ejection assembly includes a sliding hole provided on the connecting column 24. A sliding rod 22 is installed inside the sliding hole. One end of the sliding rod 22 is fixedly connected to a top plate 21, and a top-out spring 23 is fixedly installed between the top plate 21 and the connecting column 24.

[0068] When the ejection spring 23 is in its natural state, the vertical position of the top plate 21 extends to a position further below the bottom of the punching blade 1402. The sliding rod 22 can move up and down in the sliding hole. When the punching blade 1402 cuts the cardboard, the punching blade 1402 will penetrate through the knife-edge groove of the bottom plate 4. Through the thrust of the spring 23, the top plate 21 continuously ejects the remaining material, ensuring that the remaining material can smoothly pass through the knife-edge groove and fall onto the conveyor belt 7, while preventing the excess cut-off corners from accumulating in the punching blade 1402 and affecting subsequent processing. Compared with a block-shaped blade, setting the punching blade 1402 to be hollow, opening downward, and providing an ejection assembly saves more material usage and is also convenient for installation and disassembly.

[0069] Preferably, the blanking assembly includes four symmetrically installed support seats 11 fixedly mounted on the base 6. A bottom plate 4 is mounted on the support seats 11. The bottom plate 4 is provided with a knife-edge groove, which cooperates with the punching blade 1402. A transport groove is opened at the bottom of the base 6, and a conveyor belt 7 is provided in the transport groove. A pressure balance assembly is provided at the bottom of the bottom plate 4, and the pressure balance assembly is used to balance the pressure exerted on the bottom plate 4 by the pressing plate 1401. Fixing components are provided at the four corners of the bottom plate 4, and the fixing components are used to fix the bottom plate 4.

[0070] The knife-edge groove opened on the bottom plate 4 has the same shape as the remaining material to be cut. The bottom plate 4 is fixed on the support seats 11 through the fixing components. Relying on the supporting force given by the support seats 11 to the four sides of the bottom plate 4, the punching blade 1402 can cut off the remaining material of the cardboard and make the remaining material fall onto the conveyor belt 7 at the bottom of the base 6 through the knife-edge groove of the bottom plate 4 and be transported and collected. Compared with the existing die-cutting machine that cuts on a steel plate and leaves a knife-edge, the knife-edge groove opened on the bottom plate 4 can effectively reduce the wear of the punching blade 1402.

[0071] Further, the material of the punching blade 1402 is selected as Cr12MoV die steel. Since the object of punching is cardboard and the blade does not collide with the bottom plate 4 during the punching process, a medium-strength Cr12MoV die steel can be selected as the material of the blade.

[0072] Further, the fixing component includes a fixing column 5 fixedly installed at the intersection of the support seats 11. A first telescopic rod 20 is fixedly installed inside the fixing column 5. A fixing block 19 is fixedly installed at the top of the first telescopic rod 20. A return spring 18 is fixedly installed on the lower bottom surface of the fixing block 19, and the return spring 18 cooperates with the first telescopic rod 20. A fixing hole is opened on the side wall of the fixing column 5, and a positioning hole is opened on the side wall of the fixing block 19. A positioning spring 16 is fixedly installed in the positioning hole, and a positioning rod 17 is fixedly installed at one end of the positioning spring 16.

[0073] The fixed through grooves at the four corners of the bottom plate 4 and the fixed columns 5 of the support base 11 form an axial positioning reference. During installation, the operator aligns the fixed through grooves with the tops of the fixed columns 5 and presses downwards, forcing the fixed block 19 to drive the first telescopic rod 20 to move downwards. At this time, the positioning spring 16 pushes the positioning rod 17 to extend and snap into the fixing holes on the side wall of the fixed column, achieving temporary locking. When the bottom plate 4 is completely in place on the support base 11, press the positioning rod 17 to release the lock, and the return spring 18 drives the first telescopic rod 20 to move upwards, causing the positioning rod 17 to snap into the fixed through groove of the bottom plate 4 to restrain the bottom plate 4 and prevent the bottom plate 4 from moving vertically. During disassembly, press the fixed block 19. The top of the positioning rod 17 is designed in a circular arc shape. Under the guidance of the circular arc and the extrusion of the top of the fixed column 5, the positioning rod 17 enters the positioning hole, realizing the detachment of the positioning rod 17 from the fixed through groove. At this time, the bottom plate 4 can be moved upwards.

[0074] Furthermore, the pressure balance assembly includes a support plate 15 installed at the bottom of the bottom plate 4. A support column 9 is fixedly installed at the bottom of the support plate 15, and a cushion block 8 is fixedly installed at the bottom of the support column 9.

[0075] During the downward pressing process of the upper template 1, there is not only punching but also the indentation copper wire 25 pressing a crease on the cardboard, which causes pressure on each part of the bottom plate 4. And if there is a need to clean the remaining materials cut off, there needs to be a space for the remaining materials to fall under the bottom plate 4, which easily leads to uneven surface pressure distribution on the bottom plate 4 during the pressing process, thus causing bending and other situations. The pressure balance assembly relies on the supporting force given by the support plate 15 to the middle part of the bottom plate 4, and cooperates with the supporting force given by the support base 11 to the four sides of the bottom plate 4, so that when the indentation copper wire 25 on the pressing plate 1401 squeezes the cardboard to form a crease, the pressure given by the upper template 1 does not overly concentrate on a certain part of the bottom plate 4.

[0076] Furthermore, a baffle 10 is fixedly installed on the cushion block 8.

[0077] When some remaining materials fall from the knife-edge groove in the bottom plate 4, they will be blocked by the baffle 10 within the transportation range of the conveyor belt 7, ensuring that the remaining materials can be normally conveyed and preventing the remaining materials from floating to other places except the conveyor belt 7.

[0078] The present invention forms a basic structure through components such as the base 6, the upper template 1, the punch 14, and the bottom plate 4, realizing integrated punching and blanking processing. The elastic pre-pressing of the cardboard by the pressing plate 1401 is achieved by relying on the pressure spring 13, and the precise alignment design of the punching blade 1402 and the knife-edge groove of the bottom plate 4 enables the ejection assembly to synchronously push the remaining materials through the knife-edge groove onto the conveyor belt 7 after the cutting action is completed. The cardboard forms a finished handbag after a single punching, eliminating the need for an independent waste cleaning device or manual cleaning in the traditional process, significantly shortening the processing cycle and effectively avoiding waste accumulation.

[0079] The present invention constructs a modular tool rapid switching system. Aiming at the problem of high overall replacement cost of the traditional punch 14, the present invention disassembles the punch 14 into a pressure plate 1401 and a replaceable punching blade 1402. The side wall of the pressure plate 1401 is provided with a standardized tool mounting groove and configured with a quick-release mechanism to achieve rapid replacement of multi-specification tools, reduce downtime and maintenance costs, and at the same time adapt to the customized production requirements of different-shaped handbags.

[0080] The present invention optimizes the pressure distribution to extend the equipment life. Through the rigid support of the support plate 15 to the middle of the bottom plate 4 and the distributed support of the support seat 11 to the edge of the bottom plate 4, the punching pressure is evenly dispersed, greatly reducing the deformation risk of the bottom plate 4, extending the service life of key components, and improving the consistency of the indentation depth.

[0081] Working principle: When it is necessary to lift the upper template 1, the controller controls the cylinder 26 to start, and controls the piston 29 connected to it through the second telescopic rod 28 to move upward in the cavity inside the guide post 3. During this process, a negative pressure cavity is formed at the bottom cavity of the piston 29. Since a magnet is installed inside the piston 29 and a magnetic outer ring 27 is arranged in the guide sleeve 2 fixed at the four corners of the upper template 1, the magnet inside the piston 29 and the magnetic outer ring 27 attract each other, and the two move upward synchronously. Because the magnetic outer ring 27 is arranged in the upper template 1, finally the upper template 1 is driven to slide upward along the guide post 3 to realize the lifting of the upper template 1; during the return stroke, the cylinder 26 is in a free state, and the piston 29 quickly moves downward under the negative pressure of the bottom sealed cavity. The outer upper template 1 then descends at a variable speed along the guide post 3 under the dual action of gravity and the downward pulling force indirectly transmitted to the upper template 1 by the negative pressure at the bottom of the piston 29 through magnetism, realizing the blanking of the cardboard;

[0082] When punching operation is carried out, the upper template 1 moves downward. First, the punch 14 drives the pressure plate 1401 to contact the cardboard. Since the pressure spring 13 is sleeved around the limit pin 12 and abuts against the bottom surface of the counterbore and the top surface of the pressure plate 1401 at both ends respectively, in the natural state, the vertical position of the pressure plate 1401 extends to a position even lower than the bottom of the punching blade 1402. Therefore, the pressure plate 1401 will first press and fix the cardboard tightly; as the upper template 1 continues to press down, the pressure spring 13 applies pressure to the pressure plate 1401, so that the indentation copper wire 25 with the bottom surface of the pressure plate 1401 protruding 0.1 - 0.3 mm higher than the edge of the punching blade 1402 first presses a crease on the cardboard. At this time, the pressure plate 1401 is pressed into the rectangular groove in the middle of the upper template 1. Then, the punching blade 1402 continues to press down with the upper template 1, and the excess corners of the cardboard are cut off at one time;

[0083] A through hole is provided at the top of the punching blade 1402, and it is rotatably installed in the rectangular groove of the upper template 1 through the connecting column 24. A jacking component is arranged inside the connecting column 24. The jacking component includes a sliding hole opened in the connecting column 24, a sliding rod 22 installed in the sliding hole, a top plate 21 fixedly connected to one end of the sliding rod 22, and a jacking spring 23 fixedly installed between the top plate 21 and the connecting column 24; when the jacking spring 23 is in its natural state, the vertical position of the top plate 21 extends to a position further below the bottom of the punching blade 1402; when the punching blade 1402 cuts the cardboard and penetrates the cutting edge groove of the bottom plate 4, the thrust of the jacking spring 23 causes the top plate 21 to continuously push out the cut-off waste material, ensuring that the waste material can smoothly pass through the cutting edge groove and fall into the conveyor belt 7 in the transport groove at the bottom of the base 6, and at the same time preventing the waste material from accumulating inside the punching blade 1402;

[0084] The blanking component includes four symmetric support seats 11 fixedly installed on the base 6, a bottom plate 4 installed on the support seats 11, a conveyor belt 7 in the transport groove at the bottom of the base 6, a pressure balance component at the bottom of the bottom plate 4, and fixing components at the four corners of the bottom plate 4; the cutting edge groove opened on the bottom plate 4 has the same shape as the waste material to be cut. The bottom plate 4 is fixed on the support seats 11 through the fixing components. During fixing, first align the fixing through grooves at the four corners of the bottom plate 4 with the fixing columns 5, press the fixing block 19 to make it enter the fixing column 5. At this time, the positioning rod 17 is stuck in the fixing hole under the action of the positioning spring 16; when the bottom plate 4 is completely installed, press the positioning rod 17, and the reset spring 18 pushes the fixing block 19 out of the fixing column 5 and clamps the bottom plate 4; after the punching blade 1402 punches off the waste material of the cardboard, the waste material falls onto the conveyor belt 7 through the cutting edge groove of the bottom plate 4 and is transported and collected.

[0085] During this process, the pressure balance component plays a role. The support plate 15 installed at the bottom of the bottom plate 4, the support column 9 at the bottom of the support plate 15, and the cushion block 8 at the bottom of the support column 9 rely on the support force given by the support plate 15 to the middle of the bottom plate 4, and cooperate with the support force given by the support seats 11 to the four sides of the bottom plate 4, so that when the indentation copper wire 25 on the pressing plate 1401 causes a crease when squeezing the cardboard, the pressure given by the upper template 1 is evenly distributed, preventing a certain part of the bottom plate 4 from being overly stressed and bending; in addition, the baffle 10 fixedly installed on the cushion block 8 can block the waste material falling from the cutting edge groove in the bottom plate 4 within the transport range of the conveyor belt 7, ensuring that the waste material can be normally transported.
