Description

Technical Field

[0001] This utility model belongs to the field of automated production technology, specifically relating to a foldable paperless punching machine. Background Technology

[0002] Punching machines are typically used to create holes in the surface of materials to meet various production needs. Taking the automotive seat manufacturing industry as an example, the refined punching process for genuine or synthetic leather materials is a key technological step in improving the breathability, aesthetics, and functionality of seats. Traditional punching equipment generally employs a working mode of stamping dies combined with a conveying mechanism. Its core technology lies in achieving the formation of a regular array of holes on the leather surface through precise positioning. However, to ensure the stability of the leather material during high-speed stamping, existing technologies commonly lay high-strength paper under the leather, utilizing the friction between the paper and the rollers to achieve positioning and conveying of the leather. While this method effectively prevents scratches and displacement on the leather surface, the debris and fiber residue generated by the paper during repeated stamping accelerates the wear of the stamping die's cutting edge. Furthermore, the continuous consumption of paper not only increases raw material costs but also reduces the overall efficiency of the equipment due to frequent downtime for paper replacement. Additionally, the contact surface between the paper and the leather is prone to electrostatic adsorption, making waste removal after punching difficult and affecting the yield rate of subsequent processes. In addition, replacing the punching mold of existing punching equipment requires the removal of many parts, which is complicated, time-consuming and labor-intensive, and further reduces the overall efficiency of the equipment.

[0003] Therefore, developing a new type of punching equipment that does not rely on paper carriers, can effectively reduce mold wear, and is compatible with various leather materials has become a technological bottleneck that the industry urgently needs to overcome.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a foldable paperless punching machine, whose feeding component can be folded to provide working space for replacing the punching component and improve efficiency.

[0006] To achieve the above objectives, a specific embodiment of this utility model provides the following technical solution: a foldable paperless punching machine, comprising a base, a punching assembly, a feeding assembly, and a discharging assembly. The feeding assembly includes a support frame, a reinforcing plate, two drive rollers, a conveyor belt, and a pressure roller. The support frame is slidably connected to the base to move up and down relative to the base. The reinforcing plate is rotatably connected to the support frame via a rotating shaft and can be fixed relative to the support frame. The reinforcing plate can rotate downward around the rotating shaft to form a working space for replacing the punching assembly. The two drive rollers are disposed at both ends of the reinforcing plate. The conveyor belt is sleeved on the drive rollers and the reinforcing plate to transport the material to be punched. The pressure roller is disposed at one end of the reinforcing plate near the punching assembly and above the conveyor belt. The distance between the pressure roller and the conveyor belt is configured such that the pressure roller presses against the surface of the material.

[0007] In one or more embodiments of this utility model, the reinforcing plate and the support frame are connected by a connecting plate. The support frame is provided with an arc-shaped groove. The connecting plate is provided with a limiting part. The limiting part is locked in the arc-shaped groove. When the reinforcing plate switches between the working position and the folding position, the limiting part moves along the arc-shaped groove.

[0008] In one or more embodiments of this utility model, the arc-shaped groove has a first end and a second end, and when the reinforcing plate is folded, the limiting part moves from the first end to the second end.

[0009] In one or more embodiments of this utility model, the reinforcing plate is slidably connected to the connecting plate to be close to or away from the punching assembly.

[0010] In one or more embodiments of this utility model, mounting plates are provided on both sides of the reinforcing plate, a first slide rail is provided on the mounting plate, and a plurality of first sliders are provided on the connecting plate. The first slide rails are engaged in the sliders to drive the reinforcing plate to slide along the mounting plate.

[0011] In one or more embodiments of this utility model, a first locking member is provided between the connecting plate and the support frame to lock the reinforcing plate in the working position or folded position; and / or, a second locking member is provided between the assembly plate and the connecting plate to restrict the reinforcing plate from sliding relative to the connecting plate.

[0012] In one or more embodiments of this utility model, the base is provided with second slide rails on both sides in the vertical direction, and the support frame is provided with a second slider.

[0013] In one or more embodiments of this utility model, a driving member is provided on the support frame to drive the second slider to move along the second slide rail.

[0014] In one or more embodiments of this utility model, a buffer is provided at the bottom of the support frame to abut against the reinforcing plate as it changes from the working position to the folded position.

[0015] In one or more embodiments of this utility model, a mold mounting bracket is provided below the reinforcing plate, the mold mounting bracket is connected to the base, and the upper surface of the mold mounting bracket is flush with the upper surface of the base.

[0016] Compared with existing technologies, this foldable paperless punching machine differs from conventional punching machines that require component disassembly for mold replacement.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0026] like Figure 1-5 As shown, a foldable paperless punching machine according to one embodiment of the present invention includes a base 1, a punching assembly 2, a feeding assembly 3A, and a discharging assembly 3B. The punching assembly 2 is disposed on the base 1 and includes a punching die 21 for punching the material to be punched. The feeding assembly 3A is disposed on one side of the base 1 and abuts against the punching assembly 2 to convey material into the punching assembly 2. The discharging assembly 3B is disposed on the other side of the base 1 and abuts against the punching assembly 2 to receive and convey the material output from the punching assembly 2. The feeding assembly 3A includes a support frame 31, a reinforcing plate 32, two drive rollers 33, a conveyor belt 34, and a pressure roller 35. The support frame 31 is slidably connected to the base 1 to move up and down relative to the base 1. The reinforcing plate 32 is rotatably connected to the support frame 31 via a rotating shaft and can be fixed relative to the support frame 31. The reinforcing plate 32 rotates downwards around the rotating shaft to form a working space for changing the punching die 21. Two drive rollers 33 are disposed at both ends of the reinforcing plate 32. A conveyor belt 34 is fitted over the drive rollers 33 and the reinforcing plate 32 to convey material. A pressure roller 35 is disposed at one end of the reinforcing plate 32 near the perforation assembly 2 and above the conveyor belt 34. The distance between the pressure roller 35 and the conveyor belt 34 is configured such that the pressure roller presses against the surface of the material.

[0027] The working principle of this foldable paperless punching machine is as follows: The material to be punched (such as a car seat cover) is placed on the conveyor belt 34 of the feeding assembly 3A. The drive roller 33 drives the conveyor belt 34 to work, and then the material is moved to the pressure roller 35. The pressure roller 35 and the conveyor belt 34 together feed the material from one side of the punching assembly 2 into the punching assembly 2 for punching. After being fed into the punching assembly 2 by the pressure roller 35 and the conveyor belt 34 of the feeding assembly 3A, the material will come out from the other side of the punching assembly 2 and enter the discharge assembly 3B. The conveyor belt 34 and the pressure roller 35 of the discharge assembly 3B can simultaneously feed the material into the punching assembly 2 by the feeding assembly 3A and transport the material out of the punching assembly 2, thereby realizing paperless material transport.

[0028] When the punching die 21 is worn, the operator can fold the reinforcing plate 32 in the feeding assembly 3A downwards, so that the feeding assembly 3A is separated from the punching assembly 2, forming a working space that can be used to replace the punching die 21. The operator can take out the punching die 21 for replacement through the space formed by folding the reinforcing plate 32, and then install the punching die 21 back through the same space.

[0029] In the above embodiment, compared with existing punching machines that require disassembling components and then replacing the mold, this foldable paperless punching machine simplifies the mold replacement process, reduces mold replacement time, and thus improves the overall efficiency of the paperless punching machine. Furthermore, by using a conveyor belt 34 and pressure rollers 35 instead of traditional paper belt transport, paperless punching is achieved, reducing wear on the punching mold 21 and lowering production costs. The reinforcing plate 32 is rotatable and foldable relative to the support frame 31, providing working space for mold replacement.

[0030] The following provides a detailed description of the structure of the feeding assembly 3A. It should be noted that the discharging assembly 3B can be configured in the same way as the feeding assembly 3A, with both positioned on opposite sides of the base 1. Therefore, the specific configuration of the discharging assembly 3B can be referenced from the configuration of the feeding assembly 3A described below, and additions or deletions can be made to the structure of the feeding assembly 3A according to actual needs.

[0031] In one implementation, such as Figure 2 and Figure 4 As shown, the reinforcing plate 32 is connected to the support frame 31 via a connecting plate 36. The support frame 31 has an arc-shaped groove 311, and the connecting plate 36 has a limiting part 361 that engages within the arc-shaped groove 311. When the reinforcing plate 32 is folded, the connecting plate 36 rotates relative to the support frame 31, causing the limiting part 361 to move along the arc-shaped groove 311. For example, if the shape of the arc-shaped groove 311 is the same as the arc-shaped trajectory formed by the limiting part 361 rotating around a pivot, the limiting part 361 can move along the arc-shaped groove 311, thereby enabling the reinforcing plate 32 to be folded or unfolded.

[0032] Specifically, such as Figure 2 As shown, the arc-shaped groove 311 has a first end 3111 and a second end 3112. In the open state, the limiting part 361 is located within the first end 3111, and the reinforcing plate 32 is horizontally positioned, allowing material to enter the punching assembly 2 via the feeding assembly 3A and exit from the discharging assembly 3B, enabling the paperless punching machine to operate normally. When folding is required, the limiting part 361 moves along the arc-shaped groove 311, from the first end 3111 to the second end 3112 and is located within the second end 3112. Correspondingly, the reinforcing plate 32 changes from a horizontal state to a vertical state. In this position, the reinforcing plate 32 is no longer in contact with the punching assembly 2, forming a working space. The operator can use this space to disassemble and install the punching die 21.

[0033] Understandably, a first locking element 37 is provided between the connecting plate 36 and the support frame 31 to lock the reinforcing plate 32 in an open or folded state. The first locking element 37 is only unlocked when the reinforcing plate 32 needs to be folded or opened, allowing the connecting plate 36 to rotate relative to the support frame 31 and switch between the two positions. The first locking element 37 prevents the connecting plate 36, and thus the reinforcing plate 32, from rotating in a horizontal or folded state, ensuring the stability of the connection and positional relationships of each component during the drilling process and mold changes. The first locking element 37 can also lock pins or latches, or other structures that achieve a locking effect, and is correspondingly provided on the connecting plate 36 and the support frame 31.

[0034] In one embodiment, the reinforcing plate 32 is slidably connected to the connecting plate 36 to move closer to or further away from the punching assembly 2. Specifically, when the reinforcing plate 32 needs to be folded, the reinforcing plate 32 can first slide relative to the connecting plate 36 to disengage from the punching mold 21, and then fold downwards, thereby avoiding interference between the reinforcing plate 32 and the punching assembly 2 during the folding process, which would affect the folding.

[0035] When the reinforcing plate 32 needs to return from the folded state to the open state, the reinforcing plate 32 first rotates upward to the horizontal, and then moves along the connecting plate 36 toward the punching assembly 2 and abuts against the punching mold 21.

[0036] Preferably, mounting plates 38 are provided on both sides of the reinforcing plate 32. A first slide rail 381 is provided on the mounting plate 38, and a plurality of first sliders 362 are provided on the connecting plate 36. The first slide rail 381 is engaged in the first sliders 362 to drive the reinforcing plate 32 to slide along the mounting plate 38.

[0037] A second locking member 39 is provided between the assembly plate 38 and the connecting plate 36 to restrict the sliding of the reinforcing plate 32 relative to the connecting plate 36. When the reinforcing plate 32 is in the open state, the second locking member 39 is locked, and the reinforcing plate 32 cannot slide relative to the connecting plate 36. When the reinforcing plate 32 needs to be folded, the second locking member 39 is unlocked, and the reinforcing plate 32 can slide relative to the connecting plate 36 and then rotate to fold.

[0038] When changing molds, either the feeding component 3A or the discharging component 3B can be folded, or both can be folded. The specific operation method can be selected according to the space requirements and complexity of the mold change.

[0039] Because the feeding assembly 3A and the discharging assembly 3B have a relatively heavy overall structure, to avoid excessive impact on the base 1 during folding, such as... Figure 1 As shown, a buffer 314 is provided at the bottom of the support frame 31. The buffer 314 may be, for example, a damper or other components with similar effects. When the feeding assembly 3A or the discharging assembly 3B is folded towards the base 1, the reinforcing plate 32 abuts against the buffer 314, thereby offsetting the impact force exerted on the base 1 by the feeding assembly 3A or the discharging assembly 3B during the folding process, and preventing damage to the feeding assembly 3A or the discharging assembly 3B and the base 1 due to collision.

[0040] Considering the large mass of the punching die 21, in one embodiment, such as Figure 5 As shown, a mold mounting bracket 4 is provided below the reinforcing plate 32. The mold mounting bracket 4 is connected to the base 1, and its upper surface is flush with the upper surface of the base 1, so as to push the punching mold 21 from the mold mounting bracket 4 to the upper surface of the base 1. The mold mounting bracket 4 can be located on the side of the base 1 near the feeding assembly 3A, or it can be located on both sides of the base 1. When the feeding assembly 3A is folded down, the punching mold 21 can be removed along the mold mounting bracket 4, or it can be pushed along the mold mounting bracket 4 to the surface of the base 1. This arrangement allows the operator to use the mold mounting bracket 4 to disassemble or install the punching mold 21, saving physical effort and improving operational safety. Preferably, the mold mounting bracket 4 can be located below the feeding assembly 3A.

[0041] In one implementation, such as Figure 3 and Figure 4As shown, second slide rails 11 are vertically arranged on both sides of the base 1, and second sliders 312 are arranged on the support frame 31. The second sliders 312 are slidably arranged on the second slide rails 11, which can drive the support frame 31 to move up and down vertically to adjust the height of the reinforcing plate 32 relative to the base 1. With this arrangement, the height of the reinforcing plate 32 and the first conveyor belt 34 relative to the base 1 and the punching die 21 can be adjusted to ensure that the upper surface of the first conveyor belt 34 is flush with the punching die 21. In particular, when the punching die 21 is changed according to the material needs, this automatic feeding punching machine can be adapted to punching dies 21 of different heights, which improves the applicability of the paperless punching machine.

[0042] Furthermore, a driving component 313 is provided on the support frame 31 to drive the second slider 312 to move along the second slide rail 11. For example, the driving component 313 can be a lead screw, which is threadedly connected to the second slider 312, thereby driving the second slider 312 to move along the second slide rail 11 to realize the up and down adjustment of the support frame 31.

[0043] To avoid inconsistent height adjustments on both sides of the support frame 31, a linkage (not shown in the figure) is provided between the drive components 313 to synchronously drive the support frame 31 of the feeding assembly 3A or the discharging assembly 3B to move up and down relative to the base 1. Specifically, there are two drive components 313 for the feeding assembly 3A or the discharging assembly 3B. The linkage connects the two drive components 313 together, so that the two drive components 313 work synchronously, ensuring that the height adjustment on both sides of the support frame 31 is consistent. In another embodiment, the linkage can also connect the drive components 313 of both the feeding assembly 3A and the discharging assembly 3B to synchronously adjust the height of the feeding assembly 3A and the discharging assembly 3B on the base 1.

[0044] As described above, the discharge assembly 3B can be configured in the same way as the feeding assembly 3A, and may include components such as a support frame, reinforcing plate, drive roller, support frame and connecting plate.

[0045] Understandably, the foldable paperless punching machine also includes a control device and related sensors to facilitate the operation of the punching machine. The control device and sensors can be existing devices in the field, and will not be described in detail here.

[0046] Based on the above structure, the specific working method of this foldable paperless punching machine is as follows: The material to be punched (e.g., a car seat cover) is placed on the conveyor belt 34 of the feeding assembly 3A. The drive roller 33 drives the conveyor belt 34 to work, and then the material is moved to the pressure roller 35. The pressure roller 35 and the conveyor belt 34 together feed the material from one side of the punching assembly 2 into the punching die 21 for punching. After being fed into the punching die 21 by the pressure roller 35 and the conveyor belt 34 of the feeding assembly 3A, the material comes out from the other side of the punching assembly 2 and enters the discharge assembly 3B. The conveyor belt 34 and the pressure roller 35 of the discharge assembly 3B transport the material out of the punching assembly 2 for paperless material transport.

[0047] When the punching die 21 wears out, the operator first unlocks the second locking member 39, then pulls the reinforcing plate 32 to move the entire feeding assembly 3A away from the punching assembly 2 and disengage it from the punching die 21. Next, the operator unlocks the first locking member 37, the reinforcing plate 32 rotates downwards around the axis, and the limiting part 361 moves along the arc groove 311 from the first end 3111 to the second end 3112, completing the folding of the feeding assembly 3A. Then, the operator uses the die mounting bracket 4 to remove the punching die 21 to be replaced from the punching assembly 2 and move it to the external space. The new punching die 21 is then pushed back into the punching assembly 2 via the die mounting bracket 4 and fixed. Next, the operator rotates the reinforcing plate 32 upwards to a horizontal position and locks the first locking member 37. Then, the reinforcing plate 32 is slid along the connecting plate 36 until it abuts against the punching die 21, and the second locking member 39 is locked, completing the replacement of the punching die 21.

[0048] In summary, compared to existing punching machines that require component disassembly for mold replacement, the foldable paperless punching machine of this invention features a foldable reinforcing plate 32 that can rotate relative to the support frame 31, providing working space for mold replacement, simplifying the process, reducing replacement time, and thus improving the overall efficiency of the paperless punching machine. Furthermore, the use of a conveyor belt 34 and pressure rollers 35 instead of traditional paper belt transport enables paperless punching, reducing wear on the punching mold 21 and lowering production costs. Additionally, a mold mounting frame 4 facilitates mold installation and improves operational safety.
