Description

Technical Field

[0001] This utility model relates to the field of fabric clamping devices for automatic cutting beds, and more specifically, to a fabric clamping device for automatic cutting beds. Background Technology

[0002] The fabric clamping device of an automatic cutting bed is a device designed to improve the efficiency and accuracy of fabric cutting. It can stably fix the fabric and ensure that the fabric will not shift during the cutting process, thereby achieving high-quality cutting results. It is widely used in many industries such as garment manufacturing, home textiles, automotive interiors, and industrial textiles.

[0003] Automatic cutting bed fabric clamping devices mainly achieve the fabric clamping function through mechanical structure and control system. In terms of mechanical structure, components such as claws and clamps are usually used to clamp the fabric. These components can be driven manually or by electric or pneumatic means to achieve the action of clamping and releasing the fabric.

[0004] In the process of using existing automatic cutting beds, the fabric clamping device often encounters fabrics of various widths, which makes it impossible for the clamping device to flexibly adapt to changes in fabric width, and even affects production efficiency. Therefore, there is an urgent need for a new type of fabric clamping device for automatic cutting beds that can meet the requirements of clamping fabrics of different widths. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a fabric clamping device for an automatic cutting bed, which can flexibly adapt to changes in fabric width.

[0007] 2. Technical Solution

[0008] In order to solve the above problems, the present invention adopts the following technical solutions.

[0009] A fabric clamping device for an automatic cutting bed includes a worktable with two limit blocks. A first lead screw and a second lead screw are connected between the two limit blocks and have opposite threads on their respective halves. Two sliders are threaded onto the first and second lead screws and are slidably fitted with an optical shaft. One end of each slider is connected to a clamping mechanism. A first handwheel and a second handwheel are connected to one side of each limit block. A first rotating plate is fixedly fitted onto the top of the first lead screw, and a second rotating plate is fixedly fitted onto the top of the second lead screw. A first insertion hole is formed on the first rotating plate, and a second insertion hole is formed on the second rotating plate. Pins are inserted into the first and second insertion holes.

[0010] Furthermore, the clamping mechanism comprises two sets, including an upper pressure bar, a motor, a drive wheel, and a third lead screw. One end of each of the two sliders is connected to an L-shaped block. A lower pressure bar is fixedly connected to one side of the lower end of each L-shaped block. A motor is mounted on the L-shaped block, and the output shaft of the motor is fixedly connected to the drive wheel. The drive wheel meshes with a driven wheel, which is sleeved on the third lead screw. The third lead screw is sleeved on the top of the L-shaped block. A guide rod is connected between the inner side of the top of the L-shaped block and the lower pressure bar. The guide rod and the third lead screw are both sleeved on the end of the upper pressure bar.

[0011] Furthermore, the first lead screw and the second lead screw are connected to bearings at one end and are respectively connected to the inner shaft and outer shaft of the bearings. The bearings are provided with a third rotating plate, the third rotating plate is provided with a third insertion hole, the pin passes through the third insertion hole, and the pin is provided with a first baffle and a second baffle at both ends.

[0012] Furthermore, a pointer is provided at one end of each of the two sliders, and a scale is provided on one side of the lower end of each of the two sliders.

[0013] Furthermore, an optical axis is connected between the two limiting blocks, and there are two optical axes distributed on both sides of the first lead screw and the second lead screw.

[0014] Furthermore, the lower pressure strip and the upper pressure strip are both provided with rubber pads with concave and convex textures on their opposite sides.

[0015] 3. Beneficial effects

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

[0017] (1) This solution sets a first insertion hole on the first rotating plate and a second insertion hole on the second rotating plate. When the pin is inserted and passes through the first and second insertion holes, the handwheel is rotated. Through the opposite direction threads of the first and second lead screws, the sliders on both sides move towards each other at the same time. When it is necessary to make a fine adjustment to one side of the fabric, the pin is pulled out so that the first baffle stops on the side of the third rotating plate close to the second rotating plate. The handwheel is rotated so that one lead screw rotates alone to drive the slider to move to achieve the purpose of precise adjustment. It can realize bilateral coordinated movement or unilateral independent movement under different working requirements, which improves the flexibility and applicability of the device and solves the problem that the traditional fabric clamping device cannot flexibly adapt to fabrics of different widths and has low efficiency.

[0018] (2) By setting a motor on the L-shaped plate, the motor drives the active wheel and the driven wheel to rotate, which in turn drives the third lead screw to rotate, thereby precisely controlling the up and down movement of the upper pressure bar and realizing precise adjustment of the clamping force of the fabric. By setting rubber pads with concave and convex textures on the opposite side of the upper and lower pressure bars, the friction between the rubber pads and the contact surface is increased, preventing the fabric from slipping or shifting position, and further realizing the stability of the fabric clamping device.

[0019] (3) By setting an optical axis between the two limit blocks and distributing it on both sides of the first lead screw and the second lead screw, it is possible to prevent the lead screw from shaking or deviating during the movement, thereby improving the stability and accuracy of the entire sliding mechanism.

[0020] (4) By setting pointers at one end of two sets of sliders and setting scales on one side of the lower end of the sliders, the problem of operators frequently measuring dimensions manually is solved, making dimension confirmation more intuitive and quick. Operators can complete the measurement simply by making a comparison, thereby improving production efficiency. Attached Figure Description

[0027] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] Please see Figures 1-4 A fabric clamping device for an automatic cutting bed includes two limit blocks 2 on the worktable 1 to limit the movement range of sliders 6, ensuring that the fabric clamping operation is performed within a certain range. A first lead screw 3 and a second lead screw 4 are connected between the two limit blocks 2. The two lead screws are arranged in a symmetrical configuration and have threads in opposite directions. Two sliders 6 are slidably fitted with optical shafts 5, providing stable guidance for the movement of the sliders 6. One end of each slider 6 is connected to a clamping mechanism. A first handwheel 7 and a second handwheel 8 are connected to one side of the two limit blocks 2, allowing the operator to manually rotate the lead screws to adjust the position of the sliders 6. One end of each plate is connected to a clamping mechanism. The first rotating plate 24 and the second rotating plate 10 are respectively fixedly sleeved on the top ends of the first lead screw 3 and the second lead screw 4. The two rotating plates are respectively provided with a first insertion hole 25 and a second insertion hole 23. A pin 11 is inserted into the first insertion hole 25 and the second insertion hole 23. When the pin 11 is inserted into the first rotating plate 24 and the second rotating plate 10, the first lead screw 3 and the second lead screw 4 will move towards each other synchronously. When the pin 11 is removed, one of the lead screws can be rotated alone to achieve fine adjustment of the clamping position. By moving the slider 6, the clamping mechanism can be adjusted to flexibly adapt to different sizes of fabric.

[0030] Example 2:

[0031] See Figures 1 to 4 As shown, a fabric clamping device for an automatic cutting bed has two sliders 6 connected to L-shaped blocks 14 at one end, allowing the clamping mechanism to adjust its position as the sliders 6 move. A lower pressure bar 15 is fixedly connected to one side of the lower end of the L-shaped block 14. A motor 17 is mounted on the upper surface of the L-shaped block 14, transmitting the rotational power of the motor 17 to the drive wheel 18. The drive wheel 18 meshes with the driven wheel 19, which in turn drives the third lead screw 20 to rotate. Through gear transmission, the torque can be reduced to a certain extent, making the clamping force more uniform and stable. This allows the upper pressure bar 16 to move up and down along the guide rod 21, thereby realizing the pressing and releasing action of the upper pressure bar 16 and the lower pressure bar 15 on the fabric. This adapts to fabrics of different thicknesses and ensures the stability of the fabric during the cutting process.

[0032] See Figures 1 to 4As shown, the bearing 9 is provided with a third rotating plate 26, and the third rotating plate 26 has a third insertion hole 27. The two ends of the pin 11 are respectively provided with a first baffle 28 and a second baffle 29. Because the first insertion hole 25 and the second insertion hole 23 are not the same size, the second insertion hole 23 allows the first baffle 28 to pass through, while the second baffle 29 cannot pass through the first insertion hole 25, and the first baffle 28 cannot pass through the third insertion hole 27. This realizes a locking mechanism to prevent the pin from accidentally falling off when subjected to external force or vibration, thus ensuring the stability and safety of the equipment.

[0033] See Figures 1 to 4 As shown, rubber pads 22 with concave and convex textures are provided on the opposite side of the upper pressure strip 16 and the lower pressure strip 15, thereby increasing the friction between the rubber pads 22 and the contact surface, preventing the fabric from slipping or shifting position, and further realizing the stability of the fabric clamping device.

[0034] See Figures 1 to 4 An optical axis 5 is connected between the two limiting blocks 2. There are two optical axes 5, which are distributed on both sides of the first lead screw 3 and the second lead screw 4. This can prevent the lead screw from shaking or deviating during the movement, thereby improving the stability and accuracy of the entire sliding mechanism.

[0035] See Figures 1 to 4 As shown, a pointer 13 is provided at one end of each of the two sliders 6, and a scale 12 is provided on one side of the lower end of the slider 6. This solves the problem of operators frequently having to manually measure dimensions, making dimension confirmation more intuitive and quick. Operators can complete the measurement simply by making a comparison.

[0036] In use: The operator inserts pin 11 into the first socket 25, the second socket 23, and the third socket 27 to connect the three rotating plates. Then, the operator rotates the first handwheel 7 or the second handwheel 8 to make the first lead screw 3 and the second lead screw 4 rotate synchronously. Since the threads on the two lead screws are in opposite directions, the two sliders 6 will move towards or away from each other, thereby driving the clamping mechanism to adjust its position. When a fine adjustment of the clamping position is required, since the first baffle 28 cannot pass through the third socket 27, the operator can remove pin 11, causing the first baffle 28 to stop on the side of the third rotating plate 26 near the second rotating plate 10. Then, the operator rotates the first handwheel 7 or the second handwheel 8 alone to rotate one of the lead screws, causing the corresponding slider 6 and clamping mechanism to move forward. Make small position adjustments, place the fabric on the lower pressure bar 15 and adjust it to the appropriate position. Start the motor 17. The output shaft of the motor 17 drives the drive wheel 18 to rotate. The drive wheel 18 drives the driven wheel 19 to rotate through meshing, which in turn drives the third lead screw 20 to rotate. Since the upper pressure bar 16 is connected to the third lead screw 20 by a thread and is guided by the guide rod 21, the upper pressure bar 16 will rise and fall vertically along the second lead screw 20. When the upper pressure bar 16 descends to contact the fabric and continues to descend, it will clamp the fabric together with the lower pressure bar 15. This solves the problem that traditional fabric clamping devices cannot flexibly adapt to changes in fabric width, resulting in low efficiency. It realizes rapid adjustment of the clamping width, is simple and quick to operate, and improves work efficiency.

Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
