Description

Technical Field

[0001] This invention relates to the field of canvas cutting and processing technology, specifically to a canvas edge-cutting and anti-rolling pressing mechanism. Background Technology

[0002] The canvas edge-cutting and anti-curling pressing mechanism is used to process the edges of canvas during the cutting process. It presses the curled parts of the canvas flat, ensuring that the canvas maintains a regular shape during processing and meets the requirements for the flatness of the canvas edges in subsequent stages.

[0003] Patent application CN201921553433.4 discloses a canvas edge-cutting anti-rolling pressing mechanism, including a driving device and a flattening device. The flattening device is inserted into the left side of the driving device. The driving device includes a metal shell, and a metal disc is movably installed inside the metal shell. A motor is fixedly installed on the back of the metal disc. A circular block is fixedly installed on the outer edge of the surface of the metal disc. An installation block is fixedly installed on the left side of the metal block and at the left end of the metal shell. Metal rods are inserted into the left and right ends of the installation block, and a spring rope is fixedly connected to the right end of the metal rods.

[0004] During the operation of the canvas edge cutting and anti-rolling pressing mechanism, due to the uneven structure of the laminated canvas during the cutting process and the inconsistent distribution of seam tension in some stitch areas, the overall thickness of the canvas cannot be kept uniform after pressing. This thickness difference causes vibration during the cutting process, resulting in local stress concentration and causing the canvas to curl. Summary of the Invention

The outer wall of the support wheel protrudes from the surface of the slide table and contacts the outer wall of the cutting disc, and the support wheel is rotated by friction. The support wheel is used to support the canvas.

[0012] According to the above technical solution, the outer wall of the connecting rod 1 penetrates the inner wall of the support plate 1 and is connected to the inner wall of the synchronous belt. There are three sets of connecting rod 1. The three sets of connecting rod 1 are equidistantly arrayed on the inner wall of the support plate 1 with the center line of the slide table as the array axis. The end of the connecting rod 1 away from the support plate 1 is hinged to the end of the connecting rod 2 near the connecting rod 1 through a universal joint. The connecting rod 1 is driven to rotate through the contact of the support wheel with the outer wall of the cutting disc, and the three sets of connecting rod 1 are driven to rotate on the inner wall of the support plate 1 through the synchronous belt drive, while driving the guide wheel 1 to rotate on the inner wall of the support plate 2.

[0013] According to the above technical solution, a pressing mechanism is provided at the bottom of the protective cover. The pressing mechanism includes a support plate three.

[0014] According to the above technical solution, a connecting pipe is fixedly connected to the top of the pressure plate, and the outer wall of the connecting pipe is slidably connected to the inner wall of the support plate. A connecting hole is opened at the bottom of the pressure plate, and a guide wheel 2 is fixedly connected to the inner wall of the bottom of the pressure plate through a rotating shaft. There are eight sets of guide wheels 2. The four sets of guide wheels 2 located on the front side of the pressure plate are arranged equidistantly on the inner wall of the bottom of the pressure plate with the center line of the pressure plate as the array axis. The four sets of connecting holes located on the rear side of the pressure plate are arranged symmetrically with the four sets of guide wheels 2 located on the bottom of the front side of the pressure plate with the center line of the pressure plate as the axis of symmetry. The guide wheels 2 are inclined on the inner wall of the bottom of the pressure plate to guide the canvas and flatten it. The top of the connecting pipe is connected to a steam generator source set at the bottom of the workbench through the connecting pipe to heat the canvas.

There are six sets of guide wheels 1. The three sets of guide wheels 1 located on the left side of the slide table are equidistantly arranged on the inner wall of the support plate 2 with the center line of the slide table as the array axis.

All six sets of guide wheels 1 are arranged in an inclined manner on the inner wall of the support plate 2, which is used to support the canvas to both sides and flatten the canvas during the rolling process at the bottom of the canvas.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The present invention supports the canvas cutting edge through a support mechanism, increases the cutting depth of the cutting disc on the canvas, increases the stability of the cutting disc on the canvas cutting edge, and supports and guides the canvas to prevent the bottom of the canvas from lifting up during cutting, thereby increasing the stability of the cutting edge structure on the canvas cutting edge.

[0018] 2. The present invention supports and guides the canvas through a support component, and flattens the canvas during the guiding process to prevent the layers of canvas from lifting up during the cutting process, causing the layers of canvas to separate from the bottom canvas, resulting in wrinkles in the canvas, and increasing the neatness of the canvas after cutting.

[0019] 3.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1, please refer to Figures 1-6 The present invention provides a technical solution: a canvas edge cutting and anti-rolling pressing mechanism, including a workbench 1, a sliding groove 104 is provided on the surface of the workbench 1, and a support mechanism 2 is provided inside the sliding groove 104;

[0032] During the operation of the canvas edge-cutting and anti-rolling pressing mechanism, due to the uneven structure of the laminated canvas during the cutting process and the inconsistent distribution of seam tension in some stitch areas, the overall thickness of the canvas cannot be kept uniform after pressing. This thickness difference causes vibration during the cutting process, resulting in local stress concentration and causing the canvas to curl. Therefore, a support mechanism 2 is set to support the canvas edge, increase the cutting depth of the cutting disc 105 on the canvas, increase the stability of the cutting disc 105 on the canvas edge, and at the same time support and guide the canvas to prevent the bottom of the canvas from lifting up during the cutting process. A support component 21 is set to support and guide the canvas and flatten the canvas during the guiding process to prevent the laminated canvas from lifting up during the cutting process, causing the laminated canvas to separate from the bottom canvas, resulting in wrinkles in the canvas and affecting the neatness of the cut edge.

[0033] Supporting mechanism 2 includes;

[0034] The slide table 201 has its outer wall slidably connected to the wall of the sliding groove 104 via a slide rail. A support plate 204 is fixedly connected to the inner wall of the slide table 201. An adjustment frame 101 is fixedly connected to the surface of the worktable 1. A motor 102 is fixedly connected to the outer wall of the adjustment frame 101 via a connecting plate. The output end of the motor 102 is connected to a cutting disc 105 via a transmission component. A protective cover 103 is fixedly connected to the outer wall of the adjustment frame 101 via a connecting plate. A cylinder 106 is fixedly connected to the bottom of the worktable 1 via a support frame. The output end of the cylinder 106 passes through the outer wall of the worktable 1 and is fixedly connected to the outer wall of the slide table 201 via a coupling. The cylinder 106 serves as a power source to drive the slide table 201 to slide within the sliding groove 104.

[0035] A support plate 202 is fixedly connected to the inner wall of the slide table 201. A connecting rod 205 is rotatably connected to the inner wall of the support plate 202. A support wheel 203 is fixedly connected to the outer wall of the connecting rod 205. The surface of the slide table 201 is at the same horizontal plane as the surface of the worktable 1, and is used to support the canvas. There are two sets of support wheels 203, which are symmetrically arranged on the inner wall of the support plate 202 about the center line of the cutting disc 105. The outer wall of the support wheel 203 protrudes from the surface of the slide table 201 and contacts the outer wall of the cutting disc 105. The friction drives the support wheel 203 to rotate. The support wheel 203 is used to support the canvas. The outer wall of the connecting rod 205 passes through the support plate 202. The inner wall of support plate 1 202 is connected to the inner wall of synchronous belt 206. There are three sets of connecting rods 1 205, equidistantly arrayed on the inner wall of support plate 1 202 with the center line of slide table 201 as the array axis. The end of connecting rod 1 205 furthest from support plate 1 202 is hinged to the end of connecting rod 2 216 closest to connecting rod 1 205 via a universal joint. Connecting rod 1 205 rotates through contact with the outer wall of cutting disc 105 via support wheel 203, and is driven to rotate on the inner wall of support plate 1 202 via synchronous belt 206. Simultaneously, it drives guide wheel 1 211 to rotate on the inner wall of support plate 2 204. This is part of the canvas edge cutting and anti-rolling pressing mechanism. When put into use, the worker lays the canvas to be cut flat on the right side of the workbench 1. Simultaneously, the hydraulic cylinder on the outer wall of the adjustment frame 101 and the air cylinder 106 at the bottom of the workbench 1 are activated. The hydraulic cylinder on the outer wall of the adjustment frame 101 drives the motor 102, protective cover 103, and cutting disc 105 to adjust the thickness of the cut edge of the canvas. The air cylinder 106 drives the slide table 201 to slide within the sliding groove 104, adjusting synchronously with the cutting disc 105. This ensures that the support wheel 203 remains in contact with the outer wall of the cutting disc 105. The slide table 201 is interlocked with the interior of the workbench 1, allowing it to continue supporting the canvas even after adjustment by the air cylinder 106. After the cutting disc 105 is adjusted, the motor 102 is started and used as a power source to drive the cutting disc 105 to rotate, slowly pushing the canvas to the cutting disc 105 for edge cutting. During the edge cutting process, the canvas is slowly pushed by the operator to contact the outer wall of the cutting disc 105. At the same time, the top of the support wheel 203 contacts the bottom of the canvas to support the canvas. Meanwhile, the inner wall of the support wheel 203 contacts the outer wall of the cutting disc 105 and drives the support wheel 203 to rotate through friction. The support wheel 203 and the canvas are pushed forward by friction. The support force of the support wheel 203 on the canvas and the cutting disc 105 work together to generate a shearing force on the canvas to cut the edge.

[0036] A support assembly 21 is provided on the inner wall of the second support plate 204. The support assembly 21 includes a guide wheel 211. The inner wall of the guide wheel 211 is fixedly connected to the outer wall of the second connecting rod 216. The outer wall of the second connecting rod 216 is rotatably connected to the inner wall of the second support plate 204 through a bearing. A guide ring 212 is fixedly connected to the inner wall of the guide wheel 211. The inner wall of the guide ring 212 is slidably connected to the outer wall of the support rod 213. The support rod 213 protrudes from the outer wall of the guide wheel 211 and is used to support the canvas. A limit block 214 is fixedly connected to the outer wall of the support rod 213. There are two sets of limit blocks 214. The two sets of limit blocks 214 are equidistantly arrayed on the outer wall of the limit blocks 214 with the center line of the support rod 213 as the array axis. The set of limit blocks 214 closest to the second connecting rod 216 is located on the outer wall of the first set of limit blocks 214. A spring 215 is fixedly connected to the wall, and the other end of the spring 215 is fixedly connected to the inner wall of the guide wheel 211. A set of limiting blocks 214 away from the connecting rod 216 are used to limit the limiting blocks 214, so that the support rod 213 is compressed and then limited by the limiting blocks 214 to support the canvas. The outer wall of the guide wheel 211 protrudes from the surface of the slide table 201 and contacts the canvas, supporting the canvas. There are six sets of guide wheels 211. The three sets of guide wheels 211 on the left side of the slide table 201 are equidistantly arrayed on the inner wall of the support plate 204 with the center line of the slide table 201 as the array axis. The three sets of guide wheels 211 on the right side of the slide table 201 are symmetrical about the center line of the slide table 201 and are aligned with the three sets of guide wheels 211 on the left side of the slide table 201. Six sets of guide wheels 211 are symmetrically arranged on the inner wall of the support plate 204, all angled. They are used to support the canvas to both sides and flatten it during the rolling process at the bottom of the canvas. As the canvas is edge-cut by the cutting disc 105 and the support wheels 203 assist in pushing the canvas for edge cutting, the top of each guide wheel 211 contacts the bottom of the canvas. The friction generated by this contact causes the guide wheels 211 to rotate, supporting the canvas. Simultaneously, the angled guide wheels 211 stretch the canvas in an inclined direction during rotation, flattening the canvas and preventing wrinkles from forming during edge cutting, which would affect the edge cutting process. At the same time, the rotation of the support wheels 203 drives the connecting rod 1... 205 rotates on the inner wall of support plate 202, and simultaneously drives three sets of connecting rods 205 to rotate synchronously via synchronous belt 206. This causes connecting rod 205 to drive connecting rod 216 to rotate on the inner wall of support plate 204 via universal joints. Simultaneously, connecting rod 216 drives guide wheel 211 and support wheel 203 to rotate synchronously at the bottom of the canvas. As guide wheel 211 rotates at the bottom of the canvas to support and guide it, support rod 213, supported by spring 215, contacts the bottom of the canvas, providing support and preventing the stacked canvas from separating from the bottom layer during edge trimming, which would cause wrinkles in the stacked canvas. At the same time, the canvas exerts reverse pressure on support rod 213.The support rod 213 compresses the spring 215, causing it to slide against the inner wall of the guide wheel 211. This causes the limiting block 214, located outside the guide ring 212, to contact the outer wall of the guide ring 212, thus limiting the support rod 213. The limiting block 214 provides rigid support to the canvas, increasing friction with the bottom of the canvas and smoothing it out.

[0037] Example 2, based on Example 1, please refer to... Figures 7-8 The present invention provides a technical solution: a pressing mechanism 3 is provided at the bottom of the protective cover 103;

[0038] During the operation of the canvas edge cutting and anti-rolling pressing mechanism, the cutting disc 105 shears the canvas and the support wheel 203 supports the canvas, which can easily cause the canvas to curl up during the cutting process. Therefore, the pressing mechanism 3 is set up to press the canvas to prevent the canvas from curling up during the cutting process of the cutting disc 105, thereby increasing the stability of the edge cutting machine during the edge cutting process. At the same time, the canvas is heated to soften it before cutting, making it easier to flatten. The canvas is also flattened during the canvas feeding process to prevent the canvas from deforming during the edge cutting process, which would cause wrinkles and affect the neatness of the canvas edge cutting.

[0039] The pressing mechanism 3 includes a support plate 301. The top of the support plate 301 is fixedly connected to the bottom of the protective cover 103 by bolts. An electric actuator 302 is fixedly connected to the top of the support plate 301. A guide rod 305 is slidably connected to the inner wall of the support plate 301. A pressure plate 304 is fixedly connected to the bottom of the guide rod 305. The output end of the electric actuator 302 passes through the top of the support plate 301 and is fixedly connected to the top of the pressure plate 304. The top of the pressure plate 304 is slidably connected to the inner wall of the support plate 301. The pressure plate 304 is used to press the canvas. The guide rod 305... The pressure plate 304 is used to guide the pressure plate 304. A connecting pipe 303 is fixedly connected to the top of the pressure plate 304. The outer wall of the connecting pipe 303 is slidably connected to the inner wall of the support plate 301. A connecting hole 306 is opened at the bottom of the pressure plate 304. A guide wheel 307 is fixedly connected to the inner wall of the bottom of the pressure plate 304 through a rotating shaft. There are eight sets of guide wheels 307. The four sets of guide wheels 307 located on the front side of the pressure plate 304 are arranged in pairs on the inner wall of the bottom of the pressure plate 304 with the center line of the pressure plate 304 as the array axis. The four sets of connecting holes 306 located on the rear side of the pressure plate 304 are... Two sets of four guide wheels 307, symmetrically arranged around the center line of the pressure plate 304 and located at the bottom front of the pressure plate 304, are positioned on the inner wall of the bottom of the pressure plate 304. The guide wheels 307 are inclined and positioned on the inner wall of the bottom of the pressure plate 304 to guide the canvas and flatten it. When the worker lays the canvas flat on the workbench 1 and pushes it to the cutting disc 105 for edge cutting, the connecting pipe 303 is activated as a power source to output power to the pressure plate 304, causing the pressure plate 304 to descend via the guide rod 305 and contact the canvas surface. The canvas is pressed to prevent the cut edge from lifting due to the cutting force of the cutting disc 105 during the edge cutting process. At the same time, steam enters the interior of the pressure plate 304 through the connecting pipe 303 and is output to the canvas surface through the connecting hole 306 at the bottom of the pressure plate 304 to heat the canvas and soften it. During the process of the canvas being pushed, the guide wheel 307 contacts the canvas surface and drives the guide wheel 307, which is inclined and set on the inner wall of the bottom of the pressure plate 304, to roll along the canvas surface through friction, supporting and guiding the canvas and flattening it.
