Description

Technical Field

[0001] This utility model relates to a fabric cutting and fixing clamp, specifically a fabric cutting and fixing clamping device. Background Technology

[0002] Fabric is a flexible material made from fibers through spinning, weaving, knitting, or non-woven processes. It is widely used in clothing, home furnishings, and industrial applications. Common fibers include cotton, wool, silk, polyester, and nylon. Cutting is the process of cutting fabric to specific shapes and sizes. This is primarily necessary for garment manufacturing, fabric alteration, and custom fabric size design. Cutting is also a crucial step in fabric processing, directly affecting the appearance, function, and cost-effectiveness of the finished product. Whether in clothing production or home furnishing manufacturing, cutting is indispensable. Currently, specialized cutting machines are used for fabric cutting, greatly improving efficiency.

[0003] Straightening and securing the fabric before cutting it with a cutting machine can prevent it from slipping or deforming during the cutting process and ensure accurate cutting lines. Existing methods for securing fabric include magnets, clips, or weights, but these methods are inconvenient and have poor securing effects.

[0004] Some manufacturers use automatic fabric spreading machines and vacuum adsorption machines to straighten and fix the fabric. However, automatic fabric spreading machines and vacuum adsorption machines usually occupy a lot of space and are not suitable for small-scale workplaces. Changing the fabric may require a long time to reset the adsorption parameters of the adsorption machine. At the same time, their high cost, high energy consumption, restrictions on the types of fabrics that can be used, and operational complexity also need to be considered. Therefore, for small-scale or special fabric cutting, alternative solutions need to be found.

[0005] In addition, existing fabric cutting machines have two cutting methods. One is that the position of the cutting machine is fixed, and the cutting machine can only cut vertically. After stretching and fixing the fabric, it is necessary to align the pre-reserved cutting lines on the fabric with the cutting machine vertically. However, when stretching the fabric, the cutting lines of the fabric will change, making it difficult to align the cutting lines with the cutting machine vertically. This makes it impossible to guarantee the cutting accuracy, and the whole process requires manual operation.

[0006] Secondly, while the cutting machine can perform horizontal cutting, a large cutting space needs to be left in the middle of the cutting table to ensure the cutting blade can cut down. This causes the fabric to droop downwards after being laid on the cutting table, due to the excessive cutting space at the bottom of the cutting table, resulting in the fabric becoming loose. This undoubtedly increases the difficulty of stretching and fixing the fabric, and reduces cutting efficiency.

[0007] Therefore, existing fabric cutting clamping devices cannot efficiently stretch and fix the fabric. At the same time, after stretching and fixing the fabric, the pre-reserved cutting lines on the fabric will change as the fabric is stretched, which can easily lead to deviations in the cutting position and make it impossible to guarantee the cutting accuracy. Summary of the Invention

[0008] The purpose of this invention is to provide a fixed clamping device for fabric cutting, so as to solve the problems mentioned in the background art, which are that the fabric cannot be stretched and fixed efficiently, and that after stretching and fixing the fabric, the pre-reserved cutting lines on the fabric will change as the fabric is stretched, which can easily lead to deviations in the cutting position and make it impossible to guarantee the cutting accuracy.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A fabric cutting clamping device includes a base, two cutting tables for placing fabric are symmetrically arranged on the top of the base, a cutting device and a fixing mechanism for fixing and stretching the fabric are arranged on one side of the base, and a lifting mechanism is arranged on the base.

[0011] The lifting mechanism includes an opening and closing mechanism and a transmission mechanism for driving the opening and closing mechanism to slide up and down on the bottom of the two cutting tables.

[0012] The fixing mechanism includes a support seat installed on the top of the base and an electric push rod fixed inside the support seat. A guide column and a lifting block are slidably installed inside the support seat. The push rod of the electric push rod is fixed to the bottom of the lifting block. Rotating arms and pressure plates are rotatably installed at the bottom of the rotating arms on both sides of the lifting block. Two telescopic cylinders and a sliding rod slidably installed inside the telescopic cylinders are rotatably installed at the bottom of the lifting block. The sliding rod is rotatably connected to the rotating arm.

[0013] As described above, the fabric cutting and clamping device consists of a transmission mechanism connected to a sliding frame on one side of the base and a toothed plate slidably installed within the sliding frame. The top of the toothed plate is connected to an arc plate, which cooperates with an arc-shaped push plate connected to one of the pressing plates. The toothed plate is connected to a telescopic gas spring connected to one side of the sliding frame.

[0014] The fabric cutting and clamping device described above: the transmission mechanism further includes a transmission gear rotatably mounted on the bottom of the sliding frame and a shaft connected to the transmission gear. The shaft is rotatably mounted on one side of the base, and the transmission gear is located at the bottom of the toothed plate and meshes with the toothed plate.

[0015] As described above, the fabric cutting clamping device has the following features: a driving bevel gear and a driven bevel gear meshing with the driving bevel gear are fixedly sleeved at one end of the shaft, and a bidirectional lead screw is fixedly sleeved on the driven bevel gear.

[0016] The fabric cutting and clamping device described above: the opening and closing mechanism includes a column connected to one side of the base and two sliding blocks slidably mounted on the column, both of which are threaded onto the bidirectional lead screw.

[0017] As described above, the fabric cutting clamping device includes a limiting plate fixedly installed on one side of the cutting table and a beveled block slidably fitted on one side of the limiting plate. The two beveled blocks are respectively disposed between the two cutting tables and slidably installed on the two sliding blocks. Each of the two beveled blocks has a cutting groove on one side to facilitate cutting by the cutting equipment.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The fabric at the top of the two cutting tables is fixed by a fixing mechanism. The transmission mechanism is driven by the movement of the fixing mechanism, which enables the opening and closing mechanism to move between the two cutting tables. Before the stretching and fixing of the fabric begins, the middle of the cutting table is in a closed state, leaving only a narrow cutting groove. After the stretching and fixing of the fabric begins, the cutting space in the middle of the cutting table will continuously increase during the stretching and extension of the fabric. This ensures that a large cutting space is left for the cutting equipment to cut, which helps to carry out precise positioning and cutting of the fabric and ensures cutting accuracy.

[0020] It can also automatically fix both sides of the fabric, preventing it from slipping or deforming during the cutting process, and stretching the fabric so that the fixed fabric can reduce wrinkles and looseness, making the fabric surface flat and easy to cut accurately.

[0030] 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.

[0031] Please see Figures 1-8 As an embodiment of the present utility model, the fabric cutting fixing clamping device includes a base 1, two cutting tables 2 for placing fabric are symmetrically arranged on the top of the base 1, a cutting device 3 and a fixing mechanism for fixing and stretching the fabric are arranged on one side of the base 1, and a lifting mechanism is arranged on the base 1.

[0032] The lifting mechanism includes an opening and closing mechanism and a transmission mechanism for driving the opening and closing mechanism to slide up and down on the bottom of the two cutting tables 2.

[0033] In this embodiment, the fabric on the top of the two cutting tables 2 is fixed by a fixing mechanism, and the transmission mechanism is driven by the movement of the fixing mechanism, so that the transmission mechanism can drive the opening and closing mechanism to move between the two cutting tables 2.

[0034] In addition, after the fabric is placed on top of the two cutting tables 2, the fixing mechanism is then activated, which allows the fixing mechanism to unfold and straighten the fabric to both sides and press and fix the fabric. During this process, the fixing mechanism drives the transmission mechanism to move the opening and closing mechanism diagonally downward. At this time, a large cutting gap will be left between the two cutting tables 2, which makes it convenient for the cutting equipment 3 to position and cut the fixed fabric, which helps to improve the accuracy, efficiency and safety of cutting.

[0035] As a further embodiment of this utility model, the fixing mechanism includes a support base 4 installed on the top of the base 1 and an electric push rod 5 fixed inside the support base 4. A guide post 6 and a lifting block 7 are slidably installed inside the support base 4. The push rod of the electric push rod 5 is fixed to the bottom of the lifting block 7. Rotating arms 8 and pressing plates 9 are rotatably installed on the sides of the lifting block 7. Two telescopic cylinders 10 and a sliding rod 11 are rotatably installed inside the telescopic cylinders 10 at the bottom of the lifting block 7. The sliding rod 11 is rotatably connected to the rotating arm 8.

[0036] In this embodiment, the electric push rod 5 is used to lift the lifting block 7. The lifting block 7 drives the rotating arm 8 and the pressing plate 9 to move downward. At this time, the two rotating arms 8 extend outward while moving downward. Meanwhile, the telescopic cylinder 10 will deflect in coordination with the rotation of the rotating arm 8. A spring is provided inside the telescopic cylinder 10. The extension of the sliding rod 11 will compress the spring.

[0037] In addition, when the electric push rod 5 pushes the lifting block 7 to rise and fall, the guide column 6 guides the lifting block 7. At the same time, as the lifting block 7 slowly descends, the pressing plate 9 at the bottom of the rotating arm 8 will come into contact with the fabric. As the lifting block 7 continues to descend, the rotating arms 8 on both sides will extend outward. At this time, the sliding rod 11 inside the telescopic cylinder 10 will extend and compress the internal spring. At the same time, the telescopic cylinder 10 will deflect in coordination with the rotation of the rotating arm 8, which can fix the two sides of the fabric, prevent it from sliding or deforming during the cutting process, and extend the fabric. This makes the fixed fabric less wrinkled and loose, and makes the fabric surface flat, which is convenient for precise cutting.

[0038] As a further embodiment of this utility model, the transmission mechanism is connected to a sliding frame 13 on one side of the base 1 and a toothed plate 14 slidably installed in the sliding frame 13. An arc plate 15 is connected to the top of the toothed plate 14. The arc plate 15 cooperates with an arc-shaped push plate 12 connected to one of the pressing plates 9. The toothed plate 14 is connected to a telescopic gas spring 16 connected to one side of the sliding frame 13.

[0039] In this embodiment, the toothed plate 14 is slidably disposed in the sliding frame 13. The pressure plate 9 drives the arc-shaped push plate 12 to move, which in turn drives the arc plate 15 to move. When the toothed plate 14 moves, it stretches the telescopic gas spring 16.

[0040] In addition, when the pressing plate 9 moves, it will drive the arc-shaped push plate 12 to move. The arc edge at the bottom of the arc-shaped push plate 12 will abut against the arc plate 15 and drive the arc plate 15 to move to one side, so that the arc plate 15 drives the toothed plate 14 to move laterally.

[0041] As a further embodiment of this utility model, the transmission mechanism further includes a transmission gear 17 rotatably mounted on the bottom of the sliding frame 13 and a shaft 18 connected to the transmission gear 17. The shaft 18 is rotatably mounted on one side of the base 1, and the transmission gear 17 is disposed on the bottom of the toothed plate 14 and meshes with the toothed plate 14.

[0042] In this embodiment, the transmission gear 17 is rotatably mounted on the bottom of the sliding frame 13, and the shaft 18 is fixed on the transmission gear 17. The transmission gear 17 drives the shaft 18 to rotate. A support block is rotatably mounted on one side of the shaft 18, and the shaft 18 is mounted on one side of the base 1 through the support block.

[0043] In addition, the transmission gear 17 rotates through the meshing of the toothed plate 14. When the toothed plate 14 moves laterally, it will drive the transmission gear 17 at the bottom to rotate, and the transmission gear 17 will drive the shaft 18 to rotate.

[0044] As a further embodiment of this utility model, one end of the shaft 18 is fixedly fitted with a driving bevel gear 19 and a driven bevel gear 20 that meshes with the driving bevel gear 19, and a bidirectional lead screw 21 is fixedly fitted on the driven bevel gear 20.

[0045] In this embodiment, the driving bevel gear 19 is fixed to one end of the shaft 18, the driven bevel gear 20 meshes with the driving bevel gear 19, and the driven bevel gear 20 is fixed to one end of the bidirectional lead screw 21.

[0046] In addition, the rotation of the transmission gear 17 drives the shaft 18 to rotate, and the shaft 18 drives the driven bevel gear 20 to rotate through the driving bevel gear 19, which in turn drives the bidirectional lead screw 21 to rotate.

[0047] As a further embodiment of this utility model, the opening and closing mechanism includes a column 22 connected to one side of the base 1 and two sliding blocks 23 slidably mounted on the column 22. Both sliding blocks 23 are threaded onto the bidirectional lead screw 21.

[0048] In this embodiment, both sliding blocks 23 are slidably mounted on one side of the column 22, and both sliding blocks 23 are threadedly mounted on both sides of the bidirectional lead screw 21.

[0049] In addition, when the driven bevel gear 20 drives the bidirectional lead screw 21 to rotate, the bidirectional lead screw 21 will drive the two sliding blocks 23 to move in both directions. The bidirectional lead screw 21 has a self-locking function, which can maintain its position when it stops rotating and prevent reverse movement.

[0050] As a further embodiment of this utility model, the opening and closing mechanism further includes a limiting plate 26 fixedly installed on one side of the cutting table 2 and a beveled block 24 slidably fitted on one side of the limiting plate 26. The two beveled blocks 24 are respectively disposed between the two cutting tables 2 and are slidably installed on the two sliding blocks 23. Each of the two beveled blocks 24 has a cutting groove 25 on one side to facilitate cutting by the cutting device 3.

[0051] In this embodiment, the limiting plate 26 restricts the inclined block 24 to only perform oblique displacement, the sliding block 23 is used to drive the movement of the inclined block 24, the merging and cooperation of the two inclined blocks 24 realizes the filling of the gap of the cutting table 2, and the two inclined blocks 24 have a cutting groove 25 on one side to facilitate the cutting equipment 3 to cut the fabric.

[0052] In addition, the two-way lead screw 21 drives the two sliding blocks 23 to move in both directions, causing the two inclined blocks 24 to move in both directions. When the two inclined blocks 24 are horizontal with the two cutting tables 2, the cutting device 3 can only cut the fabric up and down through the cutting groove 25. As the fabric is fixed and the two ends of the fabric are extended outward, the position of the fabric and the cutting line will change. At this time, the two inclined blocks 24 move downward and leave the middle of the two cutting tables 2, leaving a large cutting space between the two cutting tables 2, which makes it convenient for the cutting device 3 to perform precise positioning and cutting of the fabric, ensuring cutting accuracy.

[0053] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
