Technical Field
[0001] This utility model relates to the field of backpack fabric cutting technology, specifically a fabric cutting device for backpack processing. Background Technology
[0002] Backpack fabric cutting refers to the process of cutting the fabric used to make backpacks into the required parts according to the design pattern and specifications.
[0003] For example, Chinese authorized patent CN219213378U (A Backpack Processing and Cutting Device) includes a cutting base, on which two U-shaped blocks are installed. Between the two U-shaped blocks are two movable blocks and a driving component for driving the two movable blocks closer to or further apart. Each movable block is equipped with an atomizing spray component and a first electric push rod for driving the atomizing spray component closer to or further away from the cutting base. The atomizing spray component is equipped with an elastic limiting component for material positioning. It also includes a water guide component installed on the cutting base for supplying water to the atomizing spray component. This utility model proposes a backpack processing and cutting device that solves the problem of multiple layers of fabric easily shifting during fabric laying, resulting in inconsistent cutting accuracy.
[0004] However, existing backpack fabric cutting methods use electric devices for top and bottom pressure cutting. These electric devices are numerous, resulting in significant power waste. Furthermore, the downward pressure cutting method often results in some parts being cut completely while others are not, leading to fraying. Additionally, the downward pressure can cause the upper surface to dent, resulting in uneven cutting on both the upper and lower surfaces. Therefore, these methods do not meet the current requirements. To address this, we propose a fabric cutting device for backpack processing. Utility Model Content
[0005] The purpose of this utility model is to provide a fabric cutting device for backpack processing, so as to solve the problems mentioned in the background art, that the existing backpack fabric cutting uses electric devices for up and down pressing and cutting, which has many electric devices, serious power waste, and the pressing and cutting can easily cause some parts to be cut completely and some parts to be not cut completely, which can easily lead to fraying. In addition, the downward pressing method can easily cause the upper surface to be concave, resulting in uneven cutting of the upper and lower surfaces.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a fabric cutting device for backpack processing, comprising: a cutting table, a first pressure plate disposed at the upper end of the cutting table near the front end, a second pressure plate disposed at the upper end of the cutting table near the rear end, inserts being heat-fused to both ends of the first and second pressure plates, leg grooves extending vertically through the upper surfaces of both sides of the cutting table being provided, with the front end of the leg grooves being open, the inserts moving along the leg grooves, and a moving groove extending vertically through the upper surfaces of the first and second pressure plates being provided, with a cutting component disposed at one end of the moving groove of the first pressure plate.
[0007] Preferably, the cutting assembly includes a cutting seat, a handle frame is provided at the upper end of the cutting seat, a connecting sleeve is provided at the center of the lower surface of the cutting seat, the cutting assembly also includes a cutting blade, a fixing plate is provided at the top end of the cutting blade, a threaded post is externally bolted to the upper end of the fixing plate, and the threaded post is threadedly connected to the connecting sleeve.
[0008] Preferably, the lower surfaces at both ends of the cutting seat are heat-fused with mounting pins, and the front and rear ends of the first pressure plate are provided with limiting seats. The upper surface of the limiting seats is provided with mounting slots, and the mounting pins are inserted into the mounting slots.
[0009] Preferably, the front and rear surfaces of the first pressure plate are provided with stabilizing grooves, and the side of the limiting seat near the first pressure plate is provided with a stabilizing seat, which moves along the stabilizing groove.
[0010] Preferably, a connecting plate is heat-fused to the center of the rear surface of the first pressure plate, and finger grooves are provided on both sides of the connecting plate. A through-type connecting plate groove is provided at the center of the front surface of the second pressure plate, and the connecting plate moves along the connecting plate groove.
[0011] Preferably, the front surfaces of both sides of the cutting table are heat-fused with baffles, and a baffle groove is formed between the baffles and the cutting table. A limiting baffle is provided at the front opening of the leg groove, and the limiting baffle is inserted along the baffle groove. A fixing screw is provided at one end of the limiting baffle, and the limiting baffle is fixed to the cutting table by the fixing screw.
[0012] Preferably, support legs are welded to the corners of the lower surface of the cutting table.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model sets a first pressure plate and a second pressure plate on the upper part of the cutting table. The connecting plate is lifted upwards, causing the first and second pressure plates to move upwards. The backpack fabric to be cut is placed on the cutting table. The connecting plate is then lowered, relying on the first and second pressure plates to press and fix the fabric, preventing movement. By adjusting the distance between the first and second pressure plates, it is suitable for pressing and fixing fabrics of different sizes. The cutting component is placed on the upper part of the first pressure plate. When placing it, the mounting post is inserted into the mounting slot to achieve a limiting and stabilizing effect, preventing tilting when moving the cutting component and improving cutting stability. The cutting blade is inserted into the moving slot, and the cutting component moves along the moving slot to cut the fabric. The cut surface is free of fraying. The entire process does not use electric devices, saving energy. Furthermore, the cutting blade is moved by a limiting mechanism to cut the fabric, which is less likely to cause unevenness due to dents. This solves the problems of existing backpack fabric cutting, which uses electric devices for up-and-down pressure cutting. These electric devices are numerous, resulting in serious power waste. In addition, the downward pressure cutting can easily cause some parts to be cut completely while others are not, leading to fraying. Moreover, the downward pressure can easily cause the upper surface to dent, resulting in uneven cutting on both the upper and lower surfaces.
[0015] (2) By heat-melting the baffle on both sides of the cutting table and forming a baffle groove between the baffle and the cutting table, the limiting baffle is inserted along the baffle groove. One end of the limiting baffle is fixed to the cutting table by fixing screws to protect the opening of the leg groove and prevent the legs of the second pressure plate and the first pressure plate from slipping off.
[0016] (3) By setting a connecting sleeve at the center of the lower surface of the cutting seat, the fixing plate with the cutting blade is fixed to the threaded post by the external bolt, and the threaded post is threaded to the connecting sleeve, thus connecting the cutting blade to the cutting seat. This facilitates the disassembly and replacement of the cutting blade, improving the convenience of replacement. The cutting blade is fixed to the cutting seat by a threaded connection instead of by a bolt, avoiding damage to the bolt hole groove caused by repeated disassembly and replacement, which leads to poor fixing stability and improves the service life of the cutting seat.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4This utility model provides an embodiment of a fabric cutting device for backpack processing, comprising: a cutting table 1, with supporting legs 13 welded to the corners of the lower surface of the cutting table 1; a first pressure plate 2 disposed at the upper end of the cutting table 1 near the front end; a second pressure plate 3 disposed at the upper end of the cutting table 1 near the rear end; insert legs 23 heat-fused to both ends of the first pressure plate 2 and the second pressure plate 3; leg grooves 9 extending vertically through the upper surfaces of both sides of the cutting table 1, with the front end of the leg grooves 9 being open, allowing the insert legs 23 to move along the leg grooves 9; and moving grooves 8 extending vertically through the upper surfaces of the first pressure plate 2 and the second pressure plate 3. A cutting component 6 is disposed at one end of the moving groove 8 of the first pressure plate 2, and the cutting component 6 includes a cutting seat 14, with the upper end of the cutting seat 14... The cutting assembly 6 includes a handle 15, a connecting sleeve 16 at the center of the lower surface of the cutting seat 14, a cutting blade 19, a fixing plate 18 at the top of the cutting blade 19, a threaded post 17 connected to the upper end of the fixing plate 18 by an external bolt, and the threaded post 17 is threadedly connected to the connecting sleeve 16. The front and rear surfaces of the first pressure plate 2 are provided with stabilizing grooves 22. A stabilizing seat 21 is provided on the side of the limiting seat 7 near the first pressure plate 2, and the stabilizing seat 21 moves along the stabilizing groove 22, thus fixing the limiting seat 7 and preventing it from falling. A connecting plate 4 is heat-fused to the center of the rear surface of the first pressure plate 2, and finger grooves 5 are provided on both sides of the connecting plate 4. A through-type connecting plate groove 25 is provided at the center of the front surface of the second pressure plate 3. The connecting plate 4 moves along the connecting plate groove 25, and the prongs 23 of the second pressure plate 3 and the first pressure plate 2 move sequentially along the leg groove 9. The connecting plate 4 is inserted into the connecting plate groove 25, connecting the first pressure plate 2 and the second pressure plate 3, facilitating vertical movement. Lifting the connecting plate 4 upwards moves the first pressure plate 2 and the second pressure plate 3 upwards. Since the prongs 23 are inserted into the leg groove 9, there will be no lateral movement of the first pressure plate 2 and the second pressure plate 3. After lifting, the backpack fabric to be cut is placed on the cutting table 1. The connecting plate 4 is then lowered, and the fabric is pressed down and fixed by the first pressure plate 2 and the second pressure plate 3 to prevent movement. By adjusting the distance between the first pressure plate 2 and the second pressure plate 3, it is suitable for pressing down and fixing fabrics of different sizes. The fixing plate 18, on which the cutting blade 19 is installed, is fixed to the threaded post 17 by external bolts, and the threaded post 17 is threadedly connected to the connecting sleeve 16, connecting the cutting blade 19 to the cutting seat 14. This facilitates the disassembly and replacement of the cutting blade 19, improving the convenience of replacement. Furthermore, the threaded connection to the cutting seat 14, rather than the direct bolt connection, avoids damage to the bolt holes and grooves caused by repeated disassembly and replacement, which could lead to poor fixing stability and improve the service life of the cutting seat 14. Then, the cutting assembly 6 is placed on the upper end of the first pressure plate 2. At this time, the cutting blade 19 is inserted into the moving groove 8. The cutting assembly 6 moves along the moving groove 8, and the fabric is cut by the cutting blade 19, with no fraying on the cut surface.
[0024] Please see Figure 2The lower surfaces of both ends of the cutting seat 14 are heat-fused with mounting pins 20. The front and rear ends of the first pressure plate 2 are provided with limit seats 7. The upper surface of the limit seat 7 is provided with a mounting slot 24, and the mounting pins 20 are inserted into the mounting slot 24. When the cutting component 6 is placed, the mounting pins 20 are inserted into the mounting slot 24, which has a limiting and stabilizing effect, preventing tilting when the cutting component 6 is moved, and improving the stability of cutting.
[0025] Please see Figure 1 , 4 Both sides of the cutting table 1 have heat-fused baffles 12 on their front surfaces, and baffle grooves are formed between the baffles 12 and the cutting table 1. A limiting baffle 10 is provided at the front opening of the leg groove 9, and the limiting baffle 10 is inserted along the baffle groove. A fixing screw 11 is provided at one end of the limiting baffle 10. The limiting baffle 10 is fixed to the cutting table 1 by the fixing screw 11, which protects the opening of the leg groove 9 and prevents the legs 23 of the second pressure plate 3 and the first pressure plate 2 from slipping off.
