Description

Technical Field

[0001] This invention relates to the field of fabric cutting technology, and in particular to a fabric cutting device for sofa cover production. Background Technology

[0002] When making sofa covers from fabric, the fabric needs to be cut. Now, cutting devices can automatically cut the fabric, and machine cutting is neater than manual cutting.

[0003] Patent publication number CN110331571B discloses a fabric cutting device, including a base, a fixed column fixedly connected to one end of the top of the base, an electric telescopic rod provided at the top of the fixed column, a blade plate provided at the telescopic end of the electric telescopic rod, a support rod fixedly connected to the top of the base and to one side of the fixed column, a horizontal plate fixedly connected to the top of the support rod, a first screw provided on the horizontal plate, a pressure plate fixedly connected to the bottom end of the first screw, and a concave block fixedly connected to one side of the bottom surface inside the base.

[0004] When using a fabric cutting device to cut fabric, the fabric is first placed on the base, then manually straightened and flattened. The first screw is then rotated to press down the pressure plate, fixing the left side of the fabric. The second screw is rotated to fix the right side of the fabric using the connecting plate. The fabric is then cut by controlling the cutting blade. As can be seen from the above operation, the fabric needs to be manually straightened and flattened before cutting. This manual assistance is inefficient and cannot reinforce the front and back sides of the cutting area, easily leading to uneven cutting. Therefore, a fabric cutting device for sofa cover production that enables more even fabric cutting is being developed. Summary of the Invention

[0005] In order to overcome the shortcomings of existing fabric cutting devices that easily lead to uneven cutting during the cutting process, the technical problem to be solved is to provide a fabric cutting device for sofa cover production that can make the fabric cut more neatly.

[0006] The technical implementation of the present invention is as follows: a fabric cutting device for sofa cover production, comprising a worktable, an electric telescopic rod, a rodless cylinder, a slider, and a cutter. The electric telescopic rod is connected to the middle of the front and rear sides of the worktable by screws. The upper part of the electric telescopic rod is connected to the rodless cylinder. The slider is slidably connected to the rodless cylinder. The cutter is connected to the bottom of the slider. The device also includes a pulling mechanism and a pressing mechanism. The pulling mechanism is provided on the worktable, and the pressing mechanism is provided on the upper part of the worktable.

[0007] As an improvement to the above solution, the pulling mechanism includes an elastic element, a first sliding frame, a roller, a double wedge frame, and a second elastic element. The first sliding frame is slidably connected to the left and right sides of the upper part of the worktable. The roller is rotatably connected to the upper part of the first sliding frame. The first elastic element is symmetrically arranged between the first sliding frame and the worktable. The double wedge frame is slidably connected to the worktable. The lower part of the double wedge frame and the first sliding frame are pressed together. The second elastic element is connected between the left part of the double wedge frame and the worktable.

[0008] As an improvement to the above solution, it also includes a second sliding frame, an electric slide rail, a rotating column, and an adhesive plate. The second sliding frame is slidably connected to the worktable, and the second sliding frame and the double wedge frame are pressed together. An electric slide rail is provided on the worktable, and the second sliding frame is connected to the slider of the electric slide rail. A rotating column is rotatably connected to the second sliding frame, and a square groove is opened in the middle of the rotating column. An adhesive plate is connected to the square groove.

[0009] As an improvement to the above scheme, it also includes a first gear, which is connected to the rotating column, and a first rack is connected to the side of the worktable near the first gear, and the first rack meshes with the first gear.

[0010] As an improvement to the above solution, the pressing mechanism includes a second gear, a second screw, a pressing element, and a second rack. The worktable is rotatably connected to the symmetrically arranged second screw. The pressing element is slidably connected to the side of the worktable near the second screw. The pressing element and the second screw are threadedly connected. The top of the second screw is fixedly connected to the second gear. The second gear meshes with the second rack. The second rack is fixedly connected to the adjacent double wedge frame.

[0011] As an improvement to the above solution, a locking mechanism is also included. The locking mechanism includes a first fixing member, a locking member, a first spring, and a square block. The top of the double wedge frame is connected to the symmetrically arranged first fixing member. The locking member is slidably connected to the first fixing member. The first spring is connected between the locking member and the first fixing member. The roller is connected to the symmetrically arranged square block. The square block and the locking member are engaged in a locking fit.

[0012] As an improvement to the above solution, a cleaning mechanism is also included. The cleaning mechanism includes a concave-convex frame, a cleaning component, a second sliding component, a sliding rail, and a second spring. The concave-convex frame is connected to the top of the second sliding frame. The sliding rail is connected to the front of the slider. The second sliding component is slidably connected to the lower part of the sliding rail. The second sliding component and the concave-convex frame are in a pressing fit. The cleaning component is connected to the bottom of the second sliding component. The second spring is connected to the upper left and right sides of the second sliding component and the inner wall of the sliding rail.

[0013] As an improvement to the above solution, an adsorption mechanism is also included. The adsorption mechanism includes a third sliding member, a suction cup, and an extrusion assembly. Two third sliding members are slidably connected at the bottom center of the worktable. The two third sliding members are symmetrically arranged on the left and right. A suction cup is connected to the top of each third sliding member. Two through holes are opened in the middle of the worktable, and the suction cups correspond to the through holes. An extrusion assembly is provided on the worktable.

[0014] As an improvement to the above solution, the extrusion assembly includes a rotating plate and a torsion spring. Two rotating plates are rotatably connected to the bottom of the worktable. The rotating plates and the bottom of the second sliding frame are extruded together. The outer side of the rotating plate is movably connected to the lower part of the third sliding member. Torsion springs are connected to the front and rear sides of the rotating plate and the worktable.

[0015] As an improvement to the above solution, it also includes a pusher frame, which is slidably connected to the worktable, with the pusher frame and the rotating plate in a pressing fit, and the pusher frame and the roller in a pressing fit.

[0016] The present invention has the following advantages: 1. The present invention controls the second sliding frame and the rotating column to move to the left by an electric slide rail, which can achieve the purpose of automatically pulling the fabric to the left. When the second sliding frame moves to the left and contacts the double wedge frame, the roller can automatically descend and straighten the fabric, which can make the cutting process more neat.

[0017] 2. As the roller descends, the invention moves the second rack to the left by the double wedge frame, thereby causing the pressing component to move automatically downward to fix the front and rear positions of the fabric cutting position, so as to make the cutting more neat.

[0018] 3. Through the cooperation between the second sliding member and the concave-convex frame, the present invention enables the sweeping member to continuously clean the cutting position of the fabric first, and then the cutter can cut neatly. Attached Figure Description

Detailed Implementation

[0029] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0030] Example 1 A fabric cutting device for sofa cover production, such as Figures 1-2 As shown, the device includes a worktable 1, an electric telescopic rod 2, a rodless cylinder 21, a slider 22, a cutter 23, a pulling mechanism 3, and a pressing mechanism 4. The electric telescopic rod 2 is connected to the middle of the front and rear sides of the worktable 1. The rodless cylinder 21 is connected to the upper part of the electric telescopic rod 2. The cutter 23 is connected to the rodless cylinder 21 through the slider 22. The rodless cylinder 21 can drive the slider 22 and the cutter 23 to move back and forth to cut the fabric. The worktable 1 is equipped with a pulling mechanism 3, which can automatically straighten the fabric. The upper part of the worktable 1 is equipped with a pressing mechanism 4, which can press and fix the front and rear sides of the fabric at the cutting position.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the pulling mechanism 3 includes an elastic element 31, a first sliding frame 32, a roller 33, a double wedge frame 34, and a second elastic element 35. The first sliding frame 32 is slidably connected to the upper left and right sides of the worktable 1. The roller 33 is rotatably connected to the upper part of the first sliding frame 32. The first elastic element 31 is connected between the front and rear sides of the first sliding frame 32 and the worktable 1. The double wedge frame 34 is slidably connected to the lower front and rear sides of the worktable 1. The double wedge frame 34 and the lower part of the first sliding frame 32 are pressed together. The second elastic element 35 is connected between the left part of the double wedge frame 34 and the worktable 1.

[0032] like Figure 2 As shown, it also includes a second sliding frame 36, an electric slide rail 37, a rotating column 38, and an adhesive plate 39. The second sliding frame 36 is slidably connected to the worktable 1. The second sliding frame 36 and the left side of the double wedge frame 34 are pressed together. The worktable 1 is provided with an electric slide rail 37. The second sliding frame 36 is connected to the slider of the electric slide rail 37. The rotating column 38 is rotatably connected to the upper part of the second sliding frame 36. A square groove is opened in the middle of the rotating column 38, and the adhesive plate 39 is connected to the square groove.

[0033] like Figure 2 As shown, it also includes a first gear 310, which is fixedly connected to the front and rear sides of the rotating column 38. The front and rear sides of the upper right part of the worktable 1 are connected to a first rack 311, which meshes with the first gear 310.

[0034] When the fabric needs to be cut, it can be pulled out from the fabric winding machine, with the left end of the fabric wrapped around the bottom of the right roller 33. The fabric end is then inserted into the square groove in the center of the rotating column 38, and the fabric end contacts the adhesive plate 39, which holds the fabric end in place. Subsequently, the electric slide rail 37 controls the second sliding frame 36 to move to the left. The leftward movement of the second sliding frame 36 drives the rotating column 38 to move to the left, and the rotating column 38 pulls the fabric end to the left via the adhesive plate 39. When the fabric is pulled to the left, the rotating column 38 moves to the left, which in turn drives the first gear 310 to move to the left. When the first gear 310 moves to the left and meshes with the first rack 311, the first gear 310 rotates, which in turn drives the rotating column 38 to rotate. The rotation of the rotating column 38 then causes the end of the fabric to rotate and roll up a portion of it. In this way, the rotating column 38 can roll up the fabric, making the fabric more firmly fixed to the rotating column 38 and preventing the fabric from separating from the rotating column 38 when it is being pulled.

[0035] After the rotating column 38 pulls the fabric below the left roller 33, the second sliding frame 36 continues to move to the left and contacts the left side of the double wedge frame 34. Then, the second sliding frame 36 drives the double wedge frame 34 to push to the left, and the second elastic element 35 is compressed. After the double wedge frame 34 moves to the left and separates from the first sliding frame 32, the first elastic element 31, which is in a stretched state, will drive the first sliding frame 32 to move downward. The first sliding frame 32 drives the roller 33 to move downward. The downward movement of the roller 33 will press the fabric down on both sides. At the same time, the roller 33 and the fabric come into contact with each other, so that the roller 33 automatically flattens the fabric and makes the fabric stick tightly to the worktable 1 for subsequent cutting.

[0036] Then, the electric telescopic rod 2 is retracted, causing the rodless cylinder 21, slider 22, and cutter 23 to move downwards, so that the cutter 23 fits against the fabric. Then, the cutter 23 is turned on, and the slider 22 is moved forward by the rodless cylinder 21. The slider 22 moves the cutter 23 forward, and the cutter 23 can automatically cut the fabric. Then, the slider 22 and cutter 23 are moved backwards to reset by the rodless cylinder 21. Then, the cutter 23 is turned off, and the electric telescopic rod 2 is extended to move the rodless cylinder 21, slider 22, and cutter 23 upwards to reset.

[0037] After cutting, the fabric wound on the rotating column 38 is removed. Then, the second sliding frame 36 is moved to the right by the electric slide rail 37. The movement of the second sliding frame 36 to the right drives the rotating column 38 to the right. When the second sliding frame 36 and the left side of the double wedge frame 34 slowly separate, the double wedge frame 34 will move to the right and reset under the action of the second elastic element 35. The wedge surfaces on both sides of the double wedge frame 34 push the first sliding frame 32 to move upward. The upward movement of the first sliding frame 32 drives the roller 33 to move upward and reset. In this way, the fabric can be released and people can take it out. When the first gear 310 and the first rack 311 mesh again, the first gear 310 will reverse and reset. The first gear 310 drives the roller 33 to reverse and reset.

[0038] like Figure 1 and Figure 4 As shown, the pressing mechanism 4 includes a second gear 41, a second screw 42, a pressing element 43, and a second rack 44. The second screw 42 is rotatably connected to both the front and rear sides of the worktable 1, and the pressing element 43 is slidably connected to both the front and rear sides of the worktable 1. The pressing element 43 and the second screw 42 are threadedly connected. The top of the second screw 42 is fixedly connected to the second gear 41, and the second gear 41 meshes with the second rack 44. The second rack 44 is fixedly connected to the adjacent double wedge frame 34.

[0039] During the cutting process of the fabric by the cutter 23, wrinkles may appear around the cutting position, which affects the cutting. Therefore, a pressing mechanism 4 is set up. When the double wedge frame 34 moves to the left, it drives the second rack 44 to move to the left. The leftward movement of the second rack 44 drives the second gear 41 to rotate. The rotation of the second gear 41 drives the second screw 42 to rotate. The rotation of the second screw 42 drives the pressing member 43 to move downward. The downward movement of the pressing member 43 presses down on both sides of the cutting part of the fabric, which reinforces the fabric and prevents wrinkles from appearing during cutting. When the double wedge frame 34 moves to the right, it drives the second rack 44 to move to the right. The rightward movement of the second rack 44 drives the second gear 41 to reverse. The reverse rotation of the second gear 41 drives the second screw 42 to reverse and reset. The second screw 42 drives the pressing member 43 to move upward and reset, releasing the fabric.

[0040] Example 2 Based on Example 1, such as Figure 1 and Figure 7 As shown, it also includes a locking mechanism 5 for locking the roller 33. The locking mechanism 5 includes a first fixing member 51, a locking member 52, a first spring 53 and a square block 54. The first fixing member 51 is connected to the left and right sides of the top of the double wedge frame 34. The locking member 52 is slidably connected to the upper part of the first fixing member 51. The first spring 53 is connected between the locking member 52 and the first fixing member 51. The square block 54 is connected to the front and rear sides of the roller 33. The square block 54 and the locking member 52 are engaged.

[0041] When the roller 33 moves downward to compress the fabric, it rotates to flatten the fabric. However, if people accidentally touch the roller 33 after it is flattened, it will cause the roller 33 to rotate, which can easily cause the fabric to wrinkle. To address this, a locking mechanism 5 is provided. When the double wedge frame 34 moves to the left to release the first sliding frame 32, the first sliding frame 32 drives the roller 33 to descend. If the double wedge frame 34 continues to move to the left, it will drive the first fixing member 51, the locking member 52, and the first spring 53 to move to the left. At this time, the locking member 52 will automatically lock the square block 54. Under the action of the first spring 53, the locking member 52 will keep pressing the square block 54, and at the same time, the locking member 52 will buffer the square block 54. When the double wedge frame 34 moves to the right to reset, it will drive the first fixing member 51, the locking member 52, and the first spring 53 to move to the right to reset, and the locking member 52 will automatically release the square block 54.

[0042] like Figure 1 , Figure 6 and Figure 7As shown, it also includes a cleaning mechanism 7 for cleaning the cutting area. The cleaning mechanism 7 includes a concave-convex frame 71, a cleaning component 72, a second sliding component 73, a sliding rail 74, and a second spring 75. The concave-convex frame 71 is connected between the top of the second sliding frame 41. The front part of the slider 22 is connected to the sliding rail 74. The lower part of the sliding rail 74 is slidably connected to the second sliding component 73, which is in a pressing fit with the concave-convex frame 71. The bottom of the second sliding component 73 is connected to the cleaning component 72. The upper left side of the second sliding component 73 is connected to the inner wall of the sliding rail 74, and the upper right side of the second sliding component 73 is also connected to the inner wall of the sliding rail 74.

[0043] When slider 22 moves the cutter 23 downwards to fit the fabric, slider 22 also moves the sliding rail 74, the second sliding member 73, and the sweeping member 72 downwards, so that the bottom of the sweeping member 72 fits the fabric. Then, when slider 22 moves the cutter 23 forward, slider 22 moves the sliding rail 74, the second sliding member 73, and the sweeping member 72 forward. When the second sliding member 73 contacts the protrusion of the bracket 71, it moves the second sliding member 73 and the sweeping member 72 to the left, and the second spring 75 deforms. After the second sliding member 73 separates from the protrusion of the bracket 71, under the action of the second spring 75, it moves the second sliding member 73 and the sweeping member 72 to the right to reset. In this way, before the cutter 23 cuts the fabric, the sweeping member 72 can clean the cutting position of the fabric, thus cleaning the impurities on the fabric to one side and preventing the impurities from affecting the cutter 23 to cut the fabric neatly.

[0044] like Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, it also includes an adsorption mechanism 8 for adsorbing the lower part of the fabric. The adsorption mechanism 8 includes a third sliding member 81, a suction cup 82, and a squeezing assembly. Two third sliding members 81 are symmetrically arranged on the left and right sides and are slidably connected to the middle position of the bottom of the worktable 1. The top of each third sliding member 81 is connected to a suction cup 82. Two through holes corresponding to the suction cups 82 are opened in the middle of the worktable 1. The worktable 1 is provided with a squeezing assembly, which can move the third sliding members 81 upward so that the suction cups 82 adsorb the fabric. The squeezing assembly includes a rotating plate 83, a torsion spring 84, and a pusher frame 85. Two rotating plates 83 are rotatably connected to the bottom of the worktable 1. The outer side of the rotating plate 83 is movably connected to the lower part of the third sliding member 81. The front and rear sides of the rotating plate 83 are connected to the worktable 1 with torsion springs 84. The pusher frame 85 is slidably connected to the upper part of the worktable 1. The pusher frame 85 and the rotating plate 83 are squeezed together. The left side of the pusher frame 85 and the left side roller 33 are squeezed together.

[0045] When the left roller 33 moves downward, it contacts the left side of the pusher 85, which pushes the pusher 85 downward. The downward movement of the pusher 85 presses the inner side of the rotating plate 83 downward, while the outer side of the rotating plate 83 swings upward. The rotating plate 83 then drives the third sliding member 81 to move upward, which in turn drives the suction cup 82 to move upward. The suction cup 82 automatically moves upward, passes through the through hole, and adsorbs the bottom of the fabric. This prevents the fabric from floating upward during the cutting process, thus avoiding affecting the cutting. When the left roller 33 moves upward, it releases the pusher 85, which in turn releases the rotating plate 83. Under the action of the torsion spring 84, the rotating plate 83 rotates and resets, causing the third sliding member 81 to drive the suction cup 82 to move downward and reset. The suction cup 82 then separates from the fabric.
