Description

Technical Field

[0001] The invention relates to a portable buckle assembly device, in particular to an automatic material belt buckle machine. Background Art

[0002] The hand buckle assembly equipment is an automated machine specially designed for the efficient installation of hand buckles. Its main structure includes a material conveying system that can accurately convey hand buckles and items to be assembled; a positioning module can ensure that the hand buckle is accurately placed in the preset position; and a pressing device firmly attaches the hand buckle through a certain pressure. When the equipment is operated, the items and hand buckles are first placed in the corresponding areas, and the positioning and pressing actions are completed in sequence after starting. It is suitable for the processing of various packaging boxes and handbags, greatly improving the assembly speed, reducing labor costs, and ensuring the consistency and stability of hand buckle assembly.

[0003] Most of the existing handle buckle assembly equipment is adapted for use with stacked handle buckles, and such stacked handle buckles need to be manually or mechanically detected and then inserted, but it is always inevitable that there will be a situation where the direction is reversed in the material strip bin. At the same time, based on the handle material strip disclosed in the prior art CN218073937U, the existing handle assembly equipment is improved to avoid the situation where the handle direction is misaligned. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an automatic strap buckle machine adapted to a handle strap to prevent the handle from being misaligned during lamination.

[0005] To achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an automatic material belt buckle machine comprises a transport platform for conveying handbags, the transport platform is respectively provided with a handbag loading device and a finished product unloading device at both ends of its transport direction, a cutting and riveting device and a feeding device are arranged from near to far at an extension perpendicular to its transport direction in the middle of the transport platform, the cutting and riveting device comprises an upper pressing mechanism and a lower pressing mechanism which are arranged corresponding to handles in different directions and close them, a buckle feeding mechanism which respectively conveys the material belt to the upper pressing mechanism and the lower pressing mechanism, and a punching mechanism for punching holes on the handbag, each buckle feeding mechanism is provided with a cutting mechanism for cutting the handle connection in the extension direction toward the respective connected pressing mechanism, the buckle feeding mechanism connected to the lower pressing mechanism is provided with a pushing mechanism for conveying the cut handle to the lower pressing mechanism at the end of the extension direction toward the lower pressing mechanism, the punching mechanism, the pushing mechanism, the upper pressing mechanism and the lower pressing mechanism are all located on the transport platform and are arranged in sequence according to the transport direction of the handbag.

[0006] The beneficial effects of the present invention are as follows: the automatic material belt buckle machine realizes the automated loading and unloading process of handbag processing by arranging handbag loading devices and finished product unloading devices at both ends of the transport platform, which greatly improves the continuity and efficiency of production, reduces manual intervention, and reduces labor costs. The cutting and riveting device arranged at the vertical extension of the middle part of the transport platform, which includes an upper pressing mechanism, a lower pressing mechanism, a buckle delivery mechanism and a punching mechanism, cooperate with each other and can accurately process handles in different directions. The cutting mechanism on the buckle delivery mechanism can accurately cut the handle connection to ensure the accuracy and quality of the handle processing, and the pushing mechanism at the end of the buckle delivery mechanism connected to the lower pressing mechanism can efficiently transport the cut handle to the lower pressing mechanism, effectively avoiding the misalignment or damage of the handle during the transfer process. The punching mechanism, pushing mechanism, upper pressing mechanism and lower pressing mechanism are arranged in sequence on the transport platform and adapted to the transport direction, so that the entire buckling process can be carried out in an orderly manner. The various mechanisms are closely connected, which reduces the time loss of process conversion and improves the overall production speed. At the same time, it also ensures the consistency and stability of the buckling of the handbags, which is conducive to the large-scale and high-quality production of handbag products and enhances the practicability and competitiveness of the equipment in related manufacturing fields.

[0007] Furthermore, one end of the handle loading device is a discharging end and a buckle feeding mechanism for conveying the handle material strip is arranged at the discharging end. The handle loading device includes a frame, a placement shaft for placing the handle material strip and a loading tray rotatably arranged on the frame, and the loading tray includes a plurality of baffles arranged on both sides of the placement shaft and extending radially from the center of the loading tray, and there is at least one group of baffles with an auxiliary stopper arranged between the radial outer sides, and a limiting space for preventing the handle material strip from loosening is formed between the two baffles and the auxiliary stopper; a partition plate is arranged at the center of the placement shaft, and the partition plate is used to divide the limiting space into two places for placing the handle material strip respectively.

[0008] By setting a limited space composed of a baffle and an auxiliary stopper, the handle material belt can be effectively prevented from loosening before being loaded into the handle loading device, ensuring the stability and accuracy of the material belt conveying. The auxiliary stopper allows the operator to easily grab and rotate the loading tray when loading the belt, greatly improving the convenience and operation efficiency of the loading belt. When the radial dimensions of the baffles are large, the auxiliary stoppers between multiple sets of baffles are convenient for the operator to grab the next set of auxiliary stoppers, avoiding the situation where it is difficult to rotate the entire loading tray when the rotation radius is too large due to only one auxiliary stopper, making the rotation operation of the loading tray more flexible and smooth, thereby improving the practicality and reliability of the handle loading device as a whole, and facilitating the efficient and orderly progress of the production and processing processes related to the handle material belt.

[0009] By setting a separation plate at the center of the placement axis to divide the limited space into two places, after the handle material tape is placed, the handle material tape can be transported upward or downward by forward and reverse installation, so that the handle material tape can be directly buckled and pressed after being sent to the assembly machine, without the need for additional flipping in the assembly machine. This not only saves the operation process and time in the assembly machine, reduces the complex movement links inside the equipment, reduces the probability of equipment failure, but also improves the assembly efficiency and accuracy of the handle and other components, making the entire production process smoother and more efficient, effectively improving the production quality and production speed of the product, reducing the production cost and production cycle, and enhancing the stability and reliability of the production system.

[0010] Furthermore, a rotating shaft is arranged on the frame near the handle loading device, and one group of baffles among several groups is hinged at both ends of the rotating shaft so that the loading tray rotates around the rotating shaft; a connecting plate is arranged at the center of the loading tray, and several groups of baffles are connected to the outer peripheral surface of the connecting plate; the frame has a limiting column between the rotating shaft and the handle loading device, and the limiting column can be abutted against a group of baffles hinged on both sides of the rotating shaft and is used to prevent the loading tray from rotating; the limiting column and the rotating shaft are located on both sides of the handle material belt.

[0011] A rotating shaft is set near the handle loading device of the frame, and a set of baffles are hinged at both ends of the rotating shaft, so that the loading tray can rotate around the rotating shaft. In this way, the space after the loading tray is opened faces the entire production line, which provides great convenience for workers to load materials. During the loading process, workers can avoid interference from other parts of the production line, and the operating space is more open, which allows them to load the handle material belt more efficiently and safely. This helps to reduce loading time and improve production efficiency, while reducing the risk of misoperation that may be caused by limited operating space, ensuring the stability and continuity of the production process, further improving the practicality and adaptability of the entire production system, and optimizing the production process and working environment.

[0012] A connecting plate is arranged at the center of the loading tray and a baffle is connected to its outer circumference, thereby ensuring the integrity and stability of the loading tray structure. A limit column is arranged between the rotating shaft and the handle loading device of the frame, and the limit column can be abutted against a group of baffles hinged on both sides of the rotating shaft. This design realizes precise control of the rotation of the loading tray. When the loading tray needs to be fixed, the limit column effectively prevents it from accidentally rotating, ensures the position accuracy of the handle material belt during the conveying process, and avoids problems such as material belt deviation and loosening due to shaking or rotation of the loading tray, thereby ensuring the stability and continuity of the material belt conveying and improving the accuracy and quality of production and processing. When the loading tray needs to be rotated for loading or maintenance operations, it only needs to separate the limit column and the baffle to flexibly rotate the loading tray. The operation is convenient and does not interfere with each other, which greatly improves the functionality and reliability of the entire handle loading device, makes the production process more efficient and orderly, and reduces the risk of equipment failure and maintenance costs.

[0013] The limit posts and the rotating shaft are located on the upper and lower sides of the handle material belt. This layout can not only effectively control the rotation of the loading tray, but also play a key role in the material belt conveying process. When the material belt is conveyed, the material belt can be pre-leveled due to the limiting effect of the rotating shaft and the limit posts on the upper and lower sides. When the pre-leveled material belt enters the subsequent processing link, it can better cooperate with related equipment or components, reduce assembly errors or processing defects caused by uneven problems such as wrinkles and bends in the material belt, and improve the assembly accuracy and quality stability of the product. At the same time, the design of being located on both sides makes the structural layout of the entire loading device more reasonable and compact, realizes multi-functional integration in a limited space, optimizes the space utilization of the equipment, is conducive to the overall layout and planning of the production line, reduces the occupation cost of the production site, and further improves the comprehensive benefits and competitiveness of the production system.

[0014] Furthermore, a speed adjustment mechanism for adjusting the rotation speed of the placement shaft is provided on both sides of the axial direction of the placement shaft. The speed adjustment mechanism is provided with a rotation adjustment block and an elastic member in sequence from the far end of the axial direction of the placement shaft toward the center of the placement shaft. When the rotation adjustment block rotates, it is used to adjust the distance between the rotation adjustment block and the corresponding end face of the placement shaft.

[0015] The speed adjustment mechanism arranged on both sides of the placement shaft axis changes the distance between it and the opposite end face of the placement shaft by rotating the adjustment block, so that the elastic part pressurizes or releases the placement shaft, realizing precise control of the rotation speed of the placement shaft. This design can adjust the conveying speed of the handle material belt to prevent the material belt from loosening or jamming due to the placement shaft speed being too fast or too slow; and in the fine processing link with high requirements for the conveying accuracy of the material belt, the rotation speed of the placement shaft can be reduced by increasing the pressure of the elastic part to ensure the smoothness and accuracy of the conveying of the material belt. This flexibility of speed adjustment effectively adapts to the diverse requirements of different production scenarios, reduces the problems of production jams and unstable product quality caused by improper conveying speed of the material belt, and greatly improves the adaptability and reliability of the entire loading device under different production processes.

[0016] Furthermore, the cutting mechanism includes a cutting knife and guide columns located on both sides of the cutting knife, the buckle feeding mechanism is provided with guide holes corresponding to the positioning columns, the cutting knife includes positioning parts arranged on both sides of the cutting knife, and a breaking groove with a width equivalent to the width of the handle connection is arranged between the two positioning parts.

[0017] Guide posts are set on both sides of the cutter in the cutting mechanism and corresponding guide holes are set on the buckle feeding mechanism. This design provides precise guidance for the movement of the cutter, ensuring that the cutter always runs along the predetermined trajectory during the cutting process, effectively avoiding the deviation or shaking of the cutter, thereby greatly improving the cutting accuracy and stability. The setting of the positioning part on the cutter and the pressure-breaking groove whose width matches the handle connection enable the cutter to accurately act on the handle connection during cutting, achieving a clean cutting effect, reducing problems such as handle damage or incomplete connection caused by improper cutting, and ensuring the quality integrity of the handle. High-precision cutting is not only conducive to the subsequent assembly process of the handle and other components, improving the quality and reliability of the overall product, but also reducing the scrap rate caused by cutting errors, saving raw material costs, and at the same time, the stable and reliable cutting process also reduces the time of equipment downtime maintenance due to abnormal cutting, further improving production efficiency.

[0018] Furthermore, there is a height difference between the buckle delivery mechanism connected to the upper pressing mechanism and the buckle delivery mechanism connected to the lower pressing mechanism, and the height difference is equivalent to the pressing distance between the lower pressing mechanism and the upper pressing mechanism; each buckle delivery mechanism is provided with a pressure plate assembly that rests on the handle material belt to prevent the material belt from jumping, a transmission wheel located on the frame and arranged at the discharge end of the handle loading device, and a pre-tensioning wheel arranged close to the pressure plate assembly; the pressure plate assembly includes a mounting column, a pressure plate shaft passing through the mounting column, and a pressure plate rotating head respectively rotatably arranged on both sides of the pressure plate shaft, and each pressure plate rotating head is fixed with an elastic pressure plate belt.

[0019] In the above scheme, the transmission wheel is the discharge end of the handle loading device, and the vertical height position of the handle material belt output in the transmission wheel and the vertical height position of the handle material belt when it enters the buckle delivery mechanism and runs smoothly are different due to the positive and negative installation of the handle material belt and the difference in the pressing height between the upper and lower pressing mechanisms, which causes the handle material belt to be offset in vertical height before entering the buckle delivery mechanism. Therefore, the pre-tensioning wheel arranged between the transmission wheel and the pressure plate assembly can provide the first step of pre-tensioning the handle material belt, and then the elastic pressure plate belt can make the handle material belt attached to it for transportation be pressed into the buckle delivery mechanism in a horizontal state and transported toward the upper and lower pressing mechanisms. In addition, if the handle material belt coming out of the transmission wheel needs to move vertically downward, the handle material belt can enter the buckle delivery mechanism from the upper end surface of the pre-tensioning wheel, and at this time, the setting position of the pre-tensioning wheel can make the handle material belt move vertically upward.

[0020] Furthermore, the buckle delivery mechanism includes a material transfer assembly for driving the handle material belt to move, the material transfer assembly includes a movable guide rail, movable plates are provided on both sides of the movable guide rail, and movable columns are provided at both ends of the movable plate, which rest against the inside of the handle and reciprocate on the movable guide rail, and the movable column can be raised and lowered on the movable plate at the same time.

[0021] The moving column first rests against the inside of the handle to drive it to move. When it moves to the end of the moving guide rail, the two moving columns drop and reset, and then rise to the inside of the handle to continue to drive the handle material belt to move, and so on to drive the handle material belt to move. In addition, the movable column can be raised and lowered, which expands its adaptability to handle material belts of different specifications and shapes, effectively reducing the need to frequently replace the material transmission components due to differences in material belts, reducing equipment maintenance costs, ensuring that the entire handle material belt cutting and riveting device can operate continuously and efficiently, improving production efficiency and product processing quality, and enhancing the versatility and practicality of the device in actual production applications.

[0022] Furthermore, a cutting mechanism arranged on a buckle feeding mechanism for conveying a material belt toward an upper pressing mechanism rises and falls synchronously with the upper pressing mechanism.

[0023] In actual operation, when the handle needs to be pressed, the upper pressing mechanism starts to move up and down, and at the same time, the cutting mechanism that rises and falls synchronously with it also moves up and down. During the lower pressing process, the cutting mechanism can be accurately at the appropriate height to ensure that the cutting of the handle connection can be carried out in time at the most appropriate position, avoiding cutting errors or inappropriate cutting timing caused by height differences, and improving the accuracy and timeliness of cutting. Moreover, the synchronous lifting setting makes the entire device more compact and coordinated in structure, reduces the complex debugging work required due to inconsistent height coordination between different components, and reduces the debugging difficulty and maintenance cost of the equipment. In addition, such coordinated movement also ensures the continuity of the handle material processing flow, so that the two key processes of cutting and pressing can be seamlessly connected, effectively improving production efficiency, ensuring the quality stability of the product, and making the operation of the entire handle material cutting and riveting device more efficient and reliable.

[0024] Furthermore, the handbag loading device includes a loading plate that can be raised and lowered, a bag pressing mechanism arranged above the loading plate and used to prevent the handbag from falling off, and a suction cup mechanism that transports the handbag to the transport platform.

[0025] In the bag loading device, the lifting loading plate provides height adjustment flexibility for the loading of bags, which can adapt to the requirements of material stacking or transmission at different heights, ensuring that the bags are in a suitable position at the initial stage of loading for subsequent operations. The bag pressing mechanism above the loading plate effectively prevents the bags from falling off during the transfer process, ensures the stability and accuracy of the loading process, reduces the material loss and equipment downtime caused by the falling of bags, and improves the success rate and efficiency of loading. The suction cup mechanism accurately transports the bags to the transport platform with its adsorption force. This non-contact handling method can avoid damage to the surface of the bags, especially for bags with soft materials or easily scratched surfaces, ensuring the appearance quality of the products. The three work together to make the bag loading process more efficient, reliable and accurate, optimize the loading process of the entire automatic belt buckle machine, lay a good foundation for subsequent cutting, riveting, buckling and other processes, and improve the overall production efficiency of the equipment and product quality stability.

[0026] Furthermore, the transport platform is provided with a first rolling wheel group and a second rolling wheel group, there is a speed difference between the first rolling wheel group and the second rolling wheel group, and the speed difference causes adjacent handbags on the transport platform to be close to each other.

[0027] The first rolling wheel group and the second rolling wheel group arranged on the transport platform have a speed difference between the two, so that the adjacent handbags are placed close to each other during the transportation process. This design brings many beneficial effects. On the one hand, the close contact of the handbags can effectively utilize the space of the transport platform. More handbags can be placed for processing within the limited table length, which improves the space utilization rate of the transport platform, and then helps to improve the overall production efficiency and realize the processing and manufacturing of more products per unit time. On the other hand, the close contact state of adjacent handbags can ensure that they maintain a relatively stable position relationship in subsequent cutting, riveting, buckling and other processes, reduce the processing position deviation problem that may occur due to uneven spacing or shaking of handbags, ensure the accuracy and consistency of each process operation, help improve the quality of the product, and make the produced handbags more standardized and accurate in terms of handle installation, further enhancing the advantages and practicality of the automatic material belt buckle machine in mass production of high-quality handbags.

[0030] The transport platform 1 includes a first rolling wheel group 11, a second rolling wheel group 12 and a conveying base plate 13 for the handbags to move thereon. There is a speed difference between the first rolling wheel group 11 and the second rolling wheel group 12, and the speed difference causes adjacent handbags on the conveying base plate 13 to be close to each other.

[0031] like Figure 2 As shown, the bag loading device 2 includes a loading plate 21 that can be raised and lowered, a bag pressing mechanism 22 disposed above the loading plate 21 and used to prevent the bag from falling off, and a suction cup mechanism 23 for transporting the bag to the transport platform. It can be seen from the figure that the bag pressing mechanism 22 and the suction cup mechanism 23 can move along the direction in which the transport platform 1 transports the bag, and the bag pressing mechanism 22 includes a blocking column 221 disposed around the bag, and the blocking column 221 is not disposed only around the bag toward the suction cup mechanism 23, and the blocking column 221 abutting against the bag perpendicular to the transport direction of the transport platform 1 can be manually adjusted and moved along the direction.

[0032] like Figure 3-10As shown, the cutting and riveting device 3 includes an upper pressing mechanism 31 and a lower pressing mechanism 32 which are arranged corresponding to the handles 61 in different directions and close them, a buckle feeding mechanism 33 which feeds the handle material strip 6 to the upper pressing mechanism 31 and the lower pressing mechanism 32 respectively, and a punching mechanism 38 for punching holes on the handbag. There is a height difference between the buckle feeding mechanism 33 connected to the upper pressing mechanism 31 and the buckle feeding mechanism 33 connected to the lower pressing mechanism 32, and the height difference is equivalent to the pressing distance between the lower pressing mechanism 32 and the upper pressing mechanism 31. The buckle feeding mechanism 33 connected to the upper pressing mechanism 31 is provided with a cutting mechanism 36 in the direction extending toward the upper pressing mechanism 31, and the cutting mechanism 36 and the upper pressing mechanism 31 are driven to rise and fall synchronously by the same driving source.

[0033] The buckle delivery mechanism 33 includes a pressure plate assembly 331 that abuts against the handle material belt 6 to prevent the material belt from jumping and a material transfer assembly 332 that drives the handle material belt 6 to move. The pressure plate assembly 331 includes a mounting column 3311, a pressure plate shaft 3312 that passes through the mounting column 3311, and pressure plate rotating heads 3313 that are rotatably arranged on both sides of the pressure plate shaft 3312. An elastic pressure plate belt 3314 is fixed to each pressure plate rotating head 3313. The material transfer assembly 332 includes a moving guide rail 3321. Both ends of the moving guide rail 3321 are provided with moving columns 3323 that abut against the inside of the handle 61 and reciprocate on the moving guide rail 3321, and the two groups of moving columns 3323 can also be lifted and lowered on the moving guide rail 3321.

[0034] The cutting mechanism 36 includes a cutting knife 362 and guide posts 361 located on both sides of the cutting knife 362. The end surface of the guide post 361 facing the handle material strip 6 is an inclined surface, and the inclined surface is arranged toward the outside of the handle 61 to correct the deviation of the handle 61 when the handle 61 is not in the correct position to prevent the cutting knife 362 from getting stuck when cutting. The corresponding positioning posts on the buckle feeding mechanism 33 are provided with guide holes 3331. The cutting knife 362 includes positioning parts 3621 arranged on both sides of the cutting knife 362 to correct the deviation of the handle connection 62 when it deviates left and right. A breaking groove 3622 with a width equivalent to that of the handle connection 62 is arranged between the two positioning parts 3621.

[0035] like Fig.11- As shown in Figure 14, the handle loading device 4 includes a frame 42 for setting the loading device, and a transmission wheel 334 for conveying the handle material belt 6 is arranged at one end of the loading device, namely the discharge end 41. The loading device includes a rotatable placement shaft 44 for placing the handle material belt 6 and a loading plate 43 rotatably arranged on the frame 42. A separation plate 45 for separating the placement shaft 44 into left and right sides is arranged at the center of the placement shaft 44; a speed adjustment mechanism 46 for adjusting the rotation speed of the placement shaft 44 is arranged on both sides of the axial direction of the placement shaft 44. The speed adjustment mechanism 46 is sequentially provided with a rotation adjustment block 461 and an elastic member 462 from the axial distal end of the placement shaft 44 toward the center of the placement shaft 44. When the rotation adjustment block 461 rotates, it is used to adjust the distance between the rotation adjustment block 461 and the corresponding end face of the placement shaft 44, thereby adjusting the pressure applied by the elastic member 462 on the placement shaft 44.

[0036] In this embodiment, the loading tray 43 includes connecting plates 431 located on both sides of the axial direction of the placement shaft 44, and three baffles 432 are radially extended on each side of the connecting plate 431, and the three baffles 432 are evenly distributed in the circumferential direction of the connecting plate 431. There are two groups of baffles 432, each of which is a group of two. An auxiliary lever 433 is connected between the baffles 432 on their radial far sides for the operator to grasp, and a limiting space 434 is formed between the two baffles 432 and the auxiliary lever 433 to prevent the handle material belt 6 from loosening. Another group of baffles 432 is hinged at both ends of the rotating shaft 421 set on the frame 42, and a limiting column 422 is also provided on the frame 42, which can abut against the group of baffles 432 hinged on both sides of the rotating shaft 421 to prevent the loading tray 43 from rotating clockwise. Furthermore, the limiting posts 422 and the rotating shaft 421 are respectively located on both sides of the handle material belt 6 to pre-level the handle material belt 6 during transportation.

[0037] The use process of this embodiment is as follows: the loading plate 21 is lowered to the part not blocked by the blocking column 221 and the material is loaded there. After the handbag is installed, the blocking column 221 is first moved to leave a certain distance between it and the handbag. Then, after the loading plate 21 enters the encirclement area surrounded by the blocking column 221, the blocking column 221 is adjusted along the position of the material width adjustment hole 211 to form an encirclement for the handbag. The suction cup mechanism 23 with openings left around the blocking column 221 absorbs the handbag and transports it to the conveying bottom plate 13.

[0038] The speed difference between the first roller group 11 and the second roller group 12 on the transport platform 1 can ensure that there is no gap between adjacent handbags, and no empty space is required.

[0039] When the bag moves to the punching mechanism 38, the punching mechanism 38 punches holes in the bag. When the two rolls of handle material 6 facing different directions enter their respective buckle feeding mechanisms 33, an opening is left between the pressure plate belt 3314 connected to the pressure plate rotating head 3313 and the bottom plate of the buckle feeding mechanism 33 for the material to enter, and the handle material 6 is gradually pressed under the reciprocating drive of the material conveying assembly 332; then the handle material 6 is sent to the cutting mechanism 36 and the handle connection 62 is cut by the cutting mechanism 36 so that the upper and lower pressing mechanisms can press it; then, the pushing mechanism 37 at the end of the buckle feeding mechanism 33 connected to the lower pressing mechanism 32 sends the handle 61 located there to the processing position of the lower pressing mechanism 32 through the pushing plate 371, and the pressing of the handle 61 and the bag is achieved in the process of the upper pressing mechanism 31 moving toward the lower pressing mechanism 32. During loading, the auxiliary stopper 433 is grasped to rotate the loading tray 43 away from the entire production line, and in this embodiment, it rotates counterclockwise. After loading, the auxiliary stopper 433 is grasped to press the loading tray 43 on the handle material belt 6 to prevent the handle material belt 6 from falling off. At this time, the set of baffles 432 hinged on both sides of the rotating shaft 421 abut against the limiting column 422. When the transmission speed of the transmission wheel 334 changes, the elastic force applied by the elastic member 462 to the placement shaft 44 is adjusted by adjusting the distance between the rotation adjustment block 461 and the placement shaft 44.

[0040] As a preferred embodiment, a cutting mechanism 36 disposed on the buckle plate 333 of the downward pressing mechanism 32 conveying the handle 61 is provided with a waste collecting block 39 above it, and a waste channel (not shown in the figure) connected to the breaking groove position is provided on the waste collecting block 39, and the waste channel (not shown in the figure) has an outlet 391 connected to an air channel with negative pressure therein.

[0041] As a preferred embodiment, a feeding speed adjustment mechanism 7 is provided under the frame 42, which includes an adjustment block 71. Hall switches are provided at both ends of the adjustment block 71. The speed can be slowed down by moving it to one side, and the speed can be increased by moving it to the other side.

[0042] In addition, how to maintain the position of the handle 61 during the pressing process of the upper pressing mechanism 31 and the lower pressing mechanism 32 belongs to the prior art and will not be explained in detail here.

[0043] The above embodiment is only one of the preferred specific embodiments of the present invention.
