Description

Technical Field

[0001] This utility model relates to the field of material punching technology, and in particular to a punching device and a punching equipment including the punching device. Background Technology

[0002] Dressings are commonly used therapeutic or nursing materials in the medical field, and foam dressings are a relatively common type. The process of making foam dressings requires a foam cutting device. This device can cut specific shapes of foam from large sheets of foam material for use in dressing production.

[0003] Existing foam punching devices generally include a cutting table and a cutting tool assembly. The cutting tool assembly includes multiple punching blades connected end-to-end to form a receiving cavity. During the punching process, the cutting tool assembly and the foam material to be processed are moved relative to each other. After the foam to be processed into dressing is cut off by the cutting tool assembly, it is embedded in the receiving cavity inside the cutting tool assembly. Then, the foam is manually removed from the receiving cavity for further processing.

[0004] Existing foam punching devices require manual removal of the foam from the receiving cavity embedded inside the cutter assembly after punching the required foam. This poses a safety hazard for the operator, and the operator's need for careful operation inevitably increases the time required. In batch foam punching operations, this affects the continuity and is not conducive to improving foam punching efficiency. Utility Model Content

[0005] The main purpose of this invention is to provide a punching device that solves the technical problem that materials are inconvenient to remove after punching in the prior art.

[0006] To achieve the above objectives, this utility model proposes a punching device, including a punching table, a cutting tool assembly, and a punching drive device. The punching drive device is connected to the cutting tool assembly and can drive the cutting tool assembly to approach or move away from the material to be processed on the punching table. Alternatively, the cutting tool assembly is located on the punching table and the punching drive device can drive the material to be processed to approach the cutting tool assembly. The cutting tool assembly includes multiple punching tools connected end to end, and the multiple punching tools surround to form a receiving cavity. The punching device also includes a pushing device, the pushing end of which corresponds to the position of the receiving cavity. When the cutting tool assembly cuts off the shaped material and collects it in the receiving cavity, the pushing device pushes at least a portion of the shaped material out of the receiving cavity.

[0007] The beneficial effects of this utility model are as follows: In the punching device of this utility model, under the drive of the punching drive device, the cutting tool assembly approaches the material, cuts off the material and collects it in the receiving cavity. Then the pushing device pushes at least part of the material out of the receiving cavity, which makes it convenient for production personnel to take out the formed material, which helps to improve the material taking efficiency, thereby improving the punching efficiency and making the continuity of batch punching better.

[0008] Preferably, the output end of the punching drive device is provided with a punching seat, which is located on the upper side of the punching table. The cutting tool assembly is located on the lower side of the punching seat, and the punching seat and the cutting tool assembly together form a receiving cavity. The pushing device is located on the punching seat and inside the receiving cavity. This arrangement helps to avoid longitudinal movement of the material and deformation during the punching process, improves the accuracy of material punching, and improves product quality.

[0009] Preferably, the pushing device includes a pushing plate and an elastic element. The elastic element is disposed on the punching seat and at least partially protrudes from the lower side of the punching seat. The pushing plate is disposed below the elastic element, such that: when the cutting tool assembly cuts the material, the material squeezes the pushing plate and compresses the elastic element; after the cutting tool assembly cuts the material, the elastic element extends and drives the pushing plate to move, thereby pushing at least a portion of the formed material out of the receiving cavity. The use of the elastic element and pushing plate allows for the adaptation to materials of various thicknesses, thus expanding the application range of the punching device.

[0010] Preferably, the lower side of the pusher plate is flush with or protrudes from the lower side of the cutter assembly. The pusher device can completely push the molding material out of the receiving cavity, causing the molding material to fall onto the punching table. The operator can then directly remove the molding material from the punching table, further improving operational safety.

[0011] Preferably, the punching seat has a mounting hole with the opening facing downwards, and the elastic element is disposed within the mounting hole. The mounting hole can limit the spring, ensuring stable operation of the spring during the material pushing process and guaranteeing the pushing effect.

[0012] Preferably, the punching stand is provided with multiple tool assemblies and multiple pusher devices, and the multiple tool assemblies and multiple pusher devices correspond one-to-one, which is conducive to improving production efficiency.

[0013] This utility model also discloses a punching device, including the above-mentioned punching device.

[0014] Preferably, the punching equipment further includes a material unwinding device, which comprises an unwinding shaft and an unwinding drive connected by a transmission. The unwinding shaft is used to wind up the material to be processed. A conveying roller assembly is provided between the unwinding shaft and the punching table, and the conveying roller assembly has a material conveying channel that connects the unwinding shaft and the punching table. This arrangement helps to reduce the tension generated by the material being pulled, reduce the degree of material deformation, and thus improve the accuracy of material punching and product quality.

[0015] Preferably, the material unwinding device further includes a tension detection structure, which comprises a tension detection plate and a sensing structure. The sensing structure is communicatively connected to the unwinding drive device. The tension detection plate is located below the unwinding shaft, and the sensing structure is located on the side of the tension detection plate near the unwinding shaft. During unwinding, the material to be processed passes sequentially through the tension detection structure and the material conveying channel to reach the punching table. When the material to be processed unwinding from the material unwinding device comes into contact with the sensing structure, the material unwinding device stops unwinding. This configuration helps to control the tension of the material within an appropriate range, further improving the accuracy of material punching and product quality.

[0016] Preferably, the punching equipment further includes a waste material winding device, with the material unwinding device and the waste material winding device located on opposite sides of the punching table. This arrangement improves the continuity of material punching and increases production efficiency. Attached Figure Description

[0032] like Figures 1 to 5 As shown, a punching device includes a punching table 1, a cutting tool assembly 2, and a punching drive device 3. The punching drive device 3 is connected to the cutting tool assembly 2 and can drive the cutting tool assembly 2 to move closer to or away from the material to be processed 101 on the punching table 1. Alternatively, the cutting tool assembly 2 is located on the punching table 1 and the punching drive device 3 can drive the material to be processed 101 closer to the cutting tool assembly 2. The cutting tool assembly 2 includes a plurality of punching tools 21 connected end to end, and the plurality of punching tools 21 surround to form a receiving cavity 22. The punching device also includes a pushing device 6, the pushing end of the pushing device 6 corresponding to the position of the receiving cavity 22. When the cutting tool assembly 2 cuts off the shaped material 102 and stores it in the receiving cavity 22, the pushing device 6 pushes at least a portion of the shaped material 102 out of the receiving cavity 22.

[0033] In the punching device of this embodiment, driven by the punching drive device 3, the cutter assembly 2 approaches the material to be processed 101, cuts off the shaped material 102 and stores it in the receiving cavity 22. Then the pusher device 6 pushes at least part of the shaped material 102 out of the receiving cavity 22, which makes it convenient for production personnel to take out the cut shaped material 102, which helps to improve the material taking efficiency, thereby improving the punching efficiency and making the continuity of batch punching better.

[0034] In this embodiment, the punching cutter 21 is strip-shaped, and the cutter assembly 2 includes four punching cutters 21 of equal length, connected end to end to form a rectangle. Alternatively, the long strip cutter can be bent to form a rectangle, with each side being a punching cutter 21. Depending on different punching requirements, different numbers of punching cutters 21 can be used to form different shapes to punch out different shaped materials 102.

[0035] In this embodiment, reference Figure 9 The material 10 before processing is called the material to be processed 101, the material after processing is called the shaped material 102, and the scrap material left after processing is called the waste scrap 103.

[0036] In this embodiment, polyurethane foam is used as an example of material 10 to illustrate the structure, working process, and effect of the punching device. In another embodiment, material 10 can also be degreased cotton, wound absorbent pad cotton cloth, etc., as long as the punching device in this embodiment can punch and process it.

[0037] In some specific embodiments, reference is made to Figure 2 The output end of the punching drive device 3 is provided with a punching seat 5, which is located on the upper side of the punching table 1. The tool assembly 2 is located on the lower side of the punching seat 5. The punching seat 5 and the tool assembly 2 together form a receiving cavity 22. The pushing device 6 is located on the punching seat 5 and inside the receiving cavity 22.

[0038] Specifically, this embodiment is a detailed structural description of the above-mentioned "punching drive device 3 is connected to the tool assembly 2 and can drive the tool assembly 2 to approach the material to be processed 101 on the punching table 1". This setting is beneficial to avoid the material 10 from moving longitudinally and deforming during the punching process, which is beneficial to improving the punching accuracy of the material 10 and improving product quality.

[0039] In addition, this specific setup, in which the cutting tool assembly 2 is connected to the punching drive device 3 and the material to be processed 101 is placed on the punching table 1 to wait for cutting, means that after cutting, the formed material 102 will be pushed out by the pushing device 6 and left on the punching table 1. Since there is no punching cutter 21 on the punching table 1, it improves safety and increases the speed of material handling for the operator.

[0040] Furthermore, the punching drive device 3 includes a punching drive cylinder 31, and the punching device also includes a mounting frame 4. The punching table 1 is mounted on the mounting frame 4. The mounting frame 4 includes a mounting plate 41 mounted above the punching table 1. The cylinder body of the punching drive cylinder 31 is mounted on the upper side of the mounting plate 41. The piston rod of the punching drive cylinder 31 passes through the mounting plate 41. The punching seat 5 is fixedly mounted on the lower end of the piston rod.

[0041] In other embodiments, the punching drive device 3 may also adopt a drive structure in the form of a hydraulic cylinder, an electric cylinder, etc., as long as it can drive the cutter assembly 2 to approach and cut the material 10.

[0042] In some other embodiments, the cutting tool assembly 2 is disposed on the cutting table 1, and the pushing device 6 is disposed on the cutting table 1 and located inside the receiving cavity 22. During cutting, the material to be processed 101 is laid on the upper side of the cutting tool assembly 2, and the cutting drive device 3 presses the material to be processed 101 downward, so that the cutting tool assembly 2 can cut off the shaped material 102 and store it in the receiving cavity 22. Finally, the pushing device 6 pushes at least a portion of the shaped material 102 out of the receiving cavity 22.

[0043] In some specific embodiments, reference is made to Figures 2 to 5The pushing device 6 includes a pushing plate 61 and an elastic member 62. The elastic member 62 is disposed on the punching seat 5 and at least partially protrudes from the lower side of the punching seat 5. The pushing plate 61 is disposed on the lower side of the elastic member 62, such that: when the cutting tool assembly 2 cuts the material 10, the material 10 squeezes the pushing plate 61 and compresses the elastic member 62; after the cutting tool assembly 2 cuts the material 10, the elastic member 62 extends and drives the pushing plate 61 to move, so as to push at least part of the formed material 102 out of the receiving cavity 22.

[0044] Specifically, the elastic element 62 includes a spring, and the lower end of the spring is provided with a pusher plate 61. The "push end of the pusher device 6" mentioned above refers to the pusher plate 61. In this embodiment, the positional relationship between the pusher device 6 and the cutter assembly 2 should follow the following principle: Before punching, the spring is pulled by the gravity of the pusher plate 61 and is in a normal extended state. At this time, the longitudinal distance between the lower side of the pusher plate 61 and the lower side of the cutter assembly 2 should satisfy the following: Before the forming material 102 is completely cut off, the forming material 102 can squeeze the pusher plate 61, so that the spring is in a compressed state, thereby ensuring that when the punching drive cylinder 31 drives the cutter assembly 2 to move upward, the spring can drive the pusher plate 61 to move, pushing at least part of the forming material 102 in the receiving cavity 22 to protrude from the lower side of the cutter assembly 2, so that the operator can easily take out the forming material 102.

[0045] By setting up the elastic element 62 and the pusher plate 61, the elasticity of the elastic element 62 can be used to adapt to materials 10 of various thicknesses, which is beneficial to expanding the application range of the punching device.

[0046] In some specific embodiments, reference is made to Figure 3 and Figure 4 The lower side of the pusher plate 61 is flush with or protrudes from the lower side of the tool assembly 2.

[0047] Specifically, before punching, the spring is pulled by the gravity of the pusher plate 61 and is in its normal extended state. At this time, the lower side of the pusher plate 61 is flush with or protrudes from the lower side of the tool assembly 2. (Reference) Figure 3 This indicates that before punching, the lower side of the pusher plate 61 is flush with the lower side of the cutter assembly 2; Reference Figure 4 This indicates that before punching, the lower side of the pusher plate 61 protrudes from the lower side of the cutter assembly 2. With this configuration, when the forming material 102 is completely cut off and the cutter assembly 2 moves upward, the pusher device 6 can completely push the forming material 102 out of the receiving cavity 22, causing the forming material 102 to fall onto the punching table 1. The operator can then directly remove the forming material 102 from the punching table 1, further improving operational safety.

[0048] In order to ensure that the cutting tool assembly 2 can cut off the formed material 102, the height c of the punching tool 21 is greater than the thickness b of the material 10.

[0049] In addition, the lower side of the pusher plate 61 is flush with or protrudes from the lower side of the cutter assembly 2, so that when the cutter assembly 2 starts cutting the material to be processed 101 or before it starts cutting the material to be processed 101, the pusher plate 61 presses the material to be processed 101 onto the punching table 1, which can reduce the deformation of the material 10 during the punching process and help improve the accuracy of punching and the quality of the product.

[0050] Furthermore, the punching seat 5 is equipped with multiple springs, the lower ends of which are connected to the pusher plate 61.

[0051] In this embodiment, the punching process is as follows: The material to be processed 101 is placed on the punching table 1. The punching drive cylinder 31 drives the tool assembly 2 to move downward. Before or when the tool assembly 2 contacts the material to be processed 101, the pusher plate 61 begins to press the material to be processed 101 on the punching table 1. At the same time, the material 101 also compresses the spring through the pusher plate 61. After punching is completed, the punching drive cylinder 31 drives the tool assembly 2 to move upward. At the same time, the spring slowly extends, and finally the shaped material 102 is pushed out of the receiving cavity 22 through the pusher plate 61.

[0052] In other embodiments, reference is made to Figure 5 Before punching, the spring is pulled by the gravity of the pusher plate 61 and is in a normal extended state. At this time, the lower side of the pusher plate 61 is located above the lower side of the cutter assembly 2. That is, the lower side of the pusher plate 61 is recessed into the lower side of the cutter assembly 2. The distance a between the lower side of the pusher plate 61 and the lower side of the cutter assembly 2 is less than the thickness b of the material to be processed 101. This ensures that before the formed material 102 is completely cut off, the material 10 can squeeze the pusher plate 61 and compress the spring, so that when the cutter assembly 2 moves upward after punching, the spring can drive the pusher plate 61 to push a part of the formed material 102 out of the receiving cavity 22.

[0053] In some specific embodiments, reference is made to Figure 2 The punching seat 5 is provided with a mounting hole 51, the mounting hole 51 is open downwards, and the elastic element 62 is partially disposed in the mounting hole 51.

[0054] The mounting hole 51 can limit the spring, ensuring that the spring can operate stably during the pushing process and ensuring the pushing effect.

[0055] In some specific embodiments, reference is made to Figure 2 The punching seat 5 is equipped with multiple tool assemblies 2 and multiple pusher devices 6, with each tool assembly 2 and pusher device 6 corresponding to the other.

[0056] Multiple tool assemblies 2 and multiple pusher devices 6 are set on the punching seat 5, which can cut multiple pieces of required shaped material 102 from the raw material of material 10 in one punching action, thereby improving production efficiency.

[0057] refer to Figures 6 to 8 This embodiment also discloses a punching device, including the above-mentioned punching device.

[0058] In some specific embodiments, reference is made to Figure 6 and Figure 7 The punching equipment also includes a material unwinding device 20, which includes an unwinding shaft 201 and an unwinding drive device connected by a transmission. The unwinding shaft 201 is used to wind up the material 101 to be processed. A conveying roller assembly 50 is provided between the unwinding shaft 201 and the punching table 1. A material conveying channel 501 is provided on the conveying roller assembly 50, which connects the unwinding shaft 201 and the punching table 1.

[0059] Specifically, the unwinding drive device includes an unwinding drive motor, and an unwinding shaft 201 is coaxially and fixedly connected to the rotating shaft of the unwinding drive motor. When it is necessary to move the corresponding part of the material to be processed 101 to the punching table 1, the unwinding drive motor drives the unwinding shaft 201 to rotate, thereby unwinding the material to be processed 101 on the unwinding shaft 201, and finally moving the unwound material to be processed 101 to the punching table 1. This arrangement helps to reduce the tension generated by the material 10 due to traction, reduce the degree of deformation of the material 10, thereby improving the punching accuracy of the material 10 and the product quality.

[0060] In some specific embodiments, reference is made to Figure 6 and Figure 7 The material unwinding device 20 also includes a tension detection structure 30, which includes a tension detection plate 301 and a sensing structure 302. The sensing structure 302 is communicatively connected to the unwinding drive device. The tension detection plate 301 is located below the unwinding shaft 201, and the sensing structure 302 is located on the side of the tension detection plate 301 near the unwinding shaft 201. During unwinding, the material to be processed 101 passes through the tension detection structure 30 and the material conveying channel 501 in sequence and arrives at the punching table 1. When the material to be processed 101 unwinding from the material unwinding device 20 comes into contact with the sensing structure 302, the material unwinding device 20 stops unwinding.

[0061] Specifically, the sensing structure 302 includes sheet-like or plate-like sensing elements, laid on the side of the tension detection plate 301 near the unwinding shaft 201. After the material to be processed 101 is unwound from the unwinding device, it falls through the tension detection structure 30, then through the material conveying channel 501, and finally reaches the punching table 1. When the portion of the unwound material 101 that has fallen touches the sensing element, it indicates that the tension of the material to be processed 101 has decreased to the expected strength and will not cause excessive pulling on the material to be processed 101 on the punching table 1. At this time, the unwinding drive device stops operating. This configuration helps to control the tension of the material 10 within an appropriate range, further improving the accuracy of punching the material 10 and the product quality.

[0062] In some specific embodiments, reference is made to Figure 8 The punching equipment also includes a waste edge material winding device 40, a material unwinding device 20, and the waste edge material winding device 40 are located on both sides of the punching table 1.

[0063] The waste material winding device 40 is used to wind up the punched waste material 103 for convenient subsequent processing. One end of the material 10 is wound onto the unwinding shaft 201, and the other end passes through the tension detection structure 30, the material conveying channel 501, and the punching table 1 before being wound onto the waste material winding device 40. After the formed material 102 is punched, the waste material 103 can be promptly pulled away from the punching table 1, and the next section of material to be processed 101 can be pulled onto the punching table 1, which can improve the continuity of punching the material 10 and increase production efficiency.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
