Description

Technical Field

[0001] This utility model relates to the field of canvas processing technology, and in particular to a canvas cutting and edge-separating device. Background Technology

[0002] Canvas is a relatively thick cotton or linen fabric, named for its original use in sails. It is generally made with a plain weave, with a small amount using a twill weave, and both warp and weft yarns are multi-ply. Canvas is usually divided into two main categories: coarse canvas and fine canvas. Currently, canvas is generally sold in rolls, and its width is relatively wide. During garment making, canvas needs to be cut into strips, which requires a canvas cutting device.

[0003] In the prior art, Chinese patent application number 202222628558.7 discloses a side-splitting structure for a canvas cutting device, including a base box. Inside the base box is a moving mechanism with two moving plates penetrating the upper surface of the base box. A top plate is fixed to the top of the two moving plates, and a cutting and side-splitting mechanism is mounted on the top plate. The cutting and side-splitting mechanism includes a cutting roller with multiple cutting blades fixed to its outer surface. The cutting and side-splitting mechanism also includes an electric push rod fixed to the lower surface of the top plate. This canvas cutting device's side-splitting structure, with its cutting and side-splitting mechanism, operates via the electric push rod to raise and lower the cutting blades. A first motor operates, causing the cutting roller to rotate the cutting blades, thus cutting and side-splitting the canvas. Compared to traditional canvas cutting devices, the simultaneous operation of multiple cutting blades maintains the consistency and flatness of the canvas strips during the cutting process and is suitable for mass production.

[0004] However, the above-mentioned technical solutions require the complete disassembly and replacement of the cutting roller when cutting canvas with different width requirements. This operation is time-consuming and labor-intensive, greatly reducing processing efficiency. Furthermore, replacing the cutting roller requires manual rotation of two screws, which is time-consuming and labor-intensive, and has a low degree of automation. Therefore, this application proposes a canvas cutting and edge-separating device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing technologies, such as the need to completely disassemble and replace the cutting roller when cutting canvas with different width requirements, which is time-consuming and labor-intensive, greatly reducing processing efficiency. Furthermore, the replacement of the cutting roller requires manual rotation of two screws, which is also time-consuming and labor-intensive, and has a low degree of automation. Therefore, this invention proposes a canvas cutting and edge-separating device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A canvas cutting and edge-separating device includes a cutting table, and the device further includes:

[0008] Two electric slide rails are provided, and both electric slide rails are fixedly installed on the top of the cutting table;

[0009] The bracket has its bottom ends slidably mounted on the top of two electric slide rails.

[0010] The first electric push rod is fixedly installed on the top of the bracket, and the output shaft of the first electric push rod passes through the bracket and is fixedly installed with a mounting bracket.

[0011] A cutting roller is disposed below the mounting frame, and insert blocks are fixedly installed at both ends of the cutting roller;

[0012] The mounting components are mounted on the mounting bracket and each mounting component mates with one of the two insert blocks.

[0013] A cutting assembly includes: a first cutting blade, two second cutting blades, a second motor, a dual-axis lead screw, and two sliders. The first cutting blade is fixedly sleeved on a cutting roller, and the two second cutting blades are slidably sleeved on the cutting roller. An installation groove is provided at the bottom of the cutting roller. The second motor is fixedly installed on the right inner wall of the installation groove. The right end of the dual-axis lead screw is fixedly installed on the output shaft of the second motor, and the left end of the dual-axis lead screw is rotatably connected to the left inner wall of the installation groove. The two sliders are slidably sleeved on the dual-axis lead screw, and the bottom end of the slider is fixedly installed on the inner wall of the corresponding second cutting blade.

[0014] As a preferred embodiment of this utility model, two stabilizing rods are fixedly installed on the top of the mounting bracket, and the top ends of the two stabilizing rods pass through the bracket and are slidably connected to the bracket.

[0015] As a preferred embodiment of this utility model, two springs are fixedly installed on the top of the mounting bracket, and the top ends of the two springs are fixedly installed on the inner wall of the top of the bracket.

[0016] In a preferred embodiment of this utility model, a limiting plate is fixedly installed on the inner wall of the second cutter, and the limiting plate is slidably connected to the cutter roller.

[0017] As a preferred embodiment of this utility model, the mounting assembly includes a first motor, a second electric push rod, a movable plate, and two sleeves. The first motor is fixedly mounted on the right side of the mounting frame, the second electric push rod is fixedly mounted on the bottom of the mounting frame, and the output shaft of the second electric push rod is fixedly mounted on the left side of the movable plate. The two sleeves are respectively disposed on the right side of the movable plate and on the output shaft of the first motor. The right sleeve is fixedly mounted on the output shaft of the first motor, and the left sleeve is rotatably connected to the movable plate. One end of the insert can be detached and inserted into the corresponding sleeve.

[0018] As a preferred embodiment of this utility model, two sliding grooves are provided on the bottom inner wall of the mounting bracket, and the top of the movable plate is slidably connected to the two sliding grooves respectively.

[0019] Beneficial effects:

[0020] 1. In order to solve the problem of cutting canvas strips of different widths, the second motor can be started to drive the dual-axis lead screw to rotate. At this time, through the threaded connection between the dual-axis lead screw and the two sliders, the two sliders can be driven to move away from each other, and at the same time, the two second cutters can be driven to move away from each other. When the two second cutters move away from each other, the distance between the two second cutters and the first cutter will change, thus adapting to the cutting of canvas strips of different widths.

[0021] 2. To facilitate the disassembly and maintenance of the cutter roller, the first cutter, and the two second cutters, the second electric push rod can be activated to move the moving plate to the left. This moving plate can then move the sleeve on the left to the left. Moving the cutter roller to the left releases the insertion limit between the two inserts and the two sleeves, thus enabling the disassembly of the cutter roller, the first cutter, and the two second cutters. This method improves the maintenance efficiency and effectiveness of the cutter roller, the first cutter, and the two second cutters, and is highly practical.

[0022] This invention achieves adjustable spacing between the two second cutters and the first cutter through a simple structure, enabling it to adapt to cutting canvas strips of different widths. It is easy to operate, saves time and effort, and improves processing efficiency. Furthermore, it allows for quick disassembly and replacement of the cutter rollers, resulting in a high degree of automation and strong practicality. Attached Figure Description

[0028] 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.

[0029] Example

[0030] Reference Figures 1-4 A canvas cutting and edge-separating device includes a cutting table 1, and the device further includes:

[0031] Two electric slide rails 2 are provided, and both electric slide rails 2 are fixedly installed on the top of the cutting table 1;

[0032] The bracket 3 is slidably mounted on the top of the two electric slide rails 2 at its bottom ends.

[0033] The first electric push rod 4 is fixedly installed on the top of the bracket 3. The output shaft of the first electric push rod 4 passes through the bracket 3 and is fixedly installed with the mounting bracket 5.

[0034] The cutting roller 9 is located below the mounting frame 5, and both ends of the cutting roller 9 are fixedly installed with insert blocks 10.

[0035] The mounting components are mounted on the mounting bracket 5 and each mounting component mates with one of the two insert blocks 10.

[0036] The cutting assembly includes a first cutting blade 15, two second cutting blades 16, a second motor 18, a dual-axis lead screw 19, and two sliders 20. The first cutting blade 15 is fixedly sleeved on the cutting roller 9, and the two second cutting blades 16 are slidably sleeved on the cutting roller 9. The bottom of the cutting roller 9 has an installation groove 17. The second motor 18 is fixedly installed on the right inner wall of the installation groove 17. The right end of the dual-axis lead screw 19 is fixedly installed on the output shaft of the second motor 18, and the left end of the dual-axis lead screw 19 is rotatably connected to the left inner wall of the installation groove 17. The two sliders 20 are slidably sleeved on the dual-axis lead screw 19, and the bottom end of the slider 20 is fixedly installed on the inner wall of the corresponding second cutting blade 16.

[0037] To address the problem of cutting canvas strips of different widths, such as Figure 4As shown, starting the second motor 18 can drive the dual-axis lead screw 19 to rotate. At this time, through the threaded connection between the dual-axis lead screw 19 and the two sliders 20, the two sliders 20 can be driven to move away from each other, and at the same time, the two second cutters 16 can be driven to move away from each other. When the two second cutters 16 move away from each other, the distance between the two second cutters 16 and the first cutter 15 will change, thereby adapting to the cutting and processing of canvas strips of different widths.

[0038] To improve the lifting stability of the mounting bracket 5, two stabilizing rods 6 are fixedly installed on the top of the mounting bracket 5. The top ends of the two stabilizing rods 6 pass through the bracket 3 and are slidably connected to the bracket 3.

[0039] To assist the mounting bracket 5 in moving upward and resetting, two springs 7 are fixedly installed on the top of the mounting bracket 5, and the top ends of the two springs 7 are fixedly installed on the top inner wall of the bracket 3.

[0040] In order to achieve a close fit between the second cutter 16 and the cutter roller 9, and to ensure the sliding adjustment stability and cutting stability of the second cutter 16, a limiting plate 21 is fixedly installed on the inner wall of the second cutter 16, and the limiting plate 21 is slidably connected to the cutter roller 9.

[0041] To facilitate the disassembly and maintenance of the cutter roller 9, the first cutter 15, and the two second cutters 16, the second electric push rod 11 is activated, which moves the moving plate 12 to the left. This moving plate 12 then moves the left sleeve 13 to the left. Moving the cutter roller 9 to the left releases the insertion limit between the two inserts 10 and the two sleeves 13, thus enabling the disassembly of the cutter roller 9, the first cutter 15, and the two second cutters 16. This method improves the efficiency and effectiveness of maintenance for the cutter roller 9, the first cutter 15, and the two second cutters 16, and is highly practical and safe. The assembly includes a first motor 8, a second electric push rod 11, a moving plate 12, and two sleeves 13. The first motor 8 is fixedly installed on the right side of the mounting frame 5, the second electric push rod 11 is fixedly installed on the bottom of the mounting frame 5, and the output shaft of the second electric push rod 11 is fixedly installed on the left side of the moving plate 12. The two sleeves 13 are respectively located on the right side of the moving plate 12 and on the output shaft of the first motor 8. The right sleeve 13 is fixedly installed on the output shaft of the first motor 8, and the left sleeve 13 is rotatably connected to the moving plate 12. One end of the insert block 10 can be detached and inserted into the corresponding sleeve 13.

[0042] In order to provide stable sliding support for the movable plate 12, two sliding grooves 14 are provided on the bottom inner wall of the mounting bracket 5, and the top of the movable plate 12 is slidably connected to the two sliding grooves 14 respectively.

[0043] It should be noted that the specific models of electric slide rail 2, first electric push rod 4, first motor 8, second electric push rod 11, and second motor 18 used can be selected by those skilled in the art. Furthermore, the electric slide rail 2, first electric push rod 4, first motor 8, second electric push rod 11, and second motor 18 mentioned above are all existing technologies, and this solution will not elaborate on them.

[0044] The working principle of this utility model is as follows: In use, firstly, the electric slide rail 2, the first electric push rod 4, the first motor 8, the second electric push rod 11, and the second motor 18 are connected to an external power source. Then, by starting the second motor 18, the dual-axis lead screw 19 can be driven to rotate. At this time, through the threaded connection between the dual-axis lead screw 19 and the two sliders 20, the two sliders 20 can be driven to move away from each other, and simultaneously, the two second cutters 16 can be driven to move away from each other. When the two second cutters 16 move away from each other, the distance between the two second cutters 16 and the first cutter 15 will increase. The design allows for the adaptation to cutting canvas strips of different widths. Additionally, by activating the second electric push rod 11, the moving plate 12 can be moved to the left. At this time, the moving plate 12 can move the left sleeve 13 to the left. Moving the cutter roller 9 to the left releases the insertion limit between the two insert blocks 10 and the two sleeves 13, thus enabling the disassembly of the cutter roller 9, the first cutter 15, and the two second cutters 16. This method improves the maintenance efficiency and effectiveness of the cutter roller 9, the first cutter 15, and the two second cutters 16, making it highly practical.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
