Description

Technical Field

[0001] This utility model belongs to the field of curtain fabric production, and in particular relates to an equidistant cutting device for curtain fabric production. Background Technology

[0002] Curtain fabric is a type of fabric made by designing and sewing decorative cloth. The main materials for curtain fabric include cotton, linen, polyester, and silk. The produced curtain fabric needs to be cut into equal-sized finished curtain sizes according to the preset dimensions so that it can be pleated and made into finished curtains.

[0003] In the curtain fabric production process, equidistant cutting is a crucial step to ensure product specifications are consistent and to meet the needs of subsequent processing and sales. Traditional equidistant cutting devices mostly achieve basic cutting functions by using fixed cutting modules or manual auxiliary positioning. However, existing devices are cumbersome to adjust equidistant dimensions. If it is necessary to switch to different width cutting specifications, it is often necessary to use tools such as wrenches to disassemble and modify the positioning components, or rely on manual marking and positioning with measuring tools. This is not only time-consuming, but also prone to cutting size deviations due to human error, affecting product consistency. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing an equidistant cutting device for curtain fabric production. Through the sliding cooperation of the slider and the groove, and the abutment and locking of the fixing bolt, the gantry frame can be pushed to slide along the fixing strip to adjust the cutting position without the need for tools such as wrenches to disassemble or modify the positioning components. This solves the problem of cumbersome and time-consuming equidistant size adjustment in traditional devices. At the same time, the sliding fit between the T-shaped slider and the T-shaped limiting groove ensures the accurate sliding of the gantry frame, reduces the cutting size deviation caused by human operation error, and ensures the uniformity of curtain fabric cutting specifications.

[0005] In view of this, the present invention provides an equidistant cutting device for curtain fabric production, including a processing table and a cutting mechanism disposed outside the processing table for equidistant cutting of curtain fabric, the cutting mechanism comprising:

[0006] Two fixing bars are respectively fixed to the two ends of the processing table. A sliding groove is opened on one side of each fixing bar, and a slider is slidably assembled in each sliding groove.

[0007] The gantry frame is equipped with a cutting blade on its inner top and has limit grooves at both ends of its inner side. One outer end of each of the two sliders extends into the corresponding limit groove and is slidably assembled with the limit groove.

[0008] Two rectangular holes are respectively opened on the outer walls of both ends of the gantry frame, and each rectangular hole is connected to the inner cavity of the corresponding limiting groove.

[0009] Two fixing bolts are respectively inserted into corresponding rectangular holes, and each fixing bolt passes through the corresponding slider and abuts against the inner cavity of the slide groove, and the fixing bolt and the corresponding slider are threaded together;

[0010] The inner cavity of the slide groove is T-shaped, the shape of the slider is T-shaped, and the slider is adapted to the inner cavity of the slide groove to improve the stability of the slider sliding in the slide groove, thereby improving the stability of the gantry frame sliding.

[0011] In this technical solution, the sliding cooperation between the slider and the groove, and the locking of the fixing bolt, eliminate the need to disassemble or modify the positioning components with tools such as wrenches. The gantry frame can be pushed to slide along the fixing strip to adjust the cutting position, which solves the problem of cumbersome and time-consuming equidistant size adjustment in traditional devices. At the same time, the sliding fit between the T-shaped slider and the T-shaped limiting groove ensures the gantry frame slides accurately, reduces the cutting size deviation caused by human operation error, and ensures the uniformity of the curtain fabric cutting specifications.

[0012] Furthermore, scale lines are engraved on the surfaces of both fixing strips.

[0013] In this technical solution, the scale lines on the surface of the fixed strip can directly provide a reference for the cutting size, eliminating the need for manual marking and positioning with additional measuring tools, simplifying the complex size measurement steps of traditional devices, and reducing marking errors.

[0014] Furthermore, a first spring is fixedly connected to the top of the inner cavity of each of the two limiting grooves, and the bottom ends of the two first springs are fixedly connected to the two sliders respectively. The elastic force of the first spring is greater than the sum of the weight of the gantry and the cutting blade, which is used to ensure that the cutting blade can automatically reset after cutting the curtain fabric by moving down.

[0015] In this technical solution, the first spring can drive the cutting blade to automatically reset after cutting, eliminating the need for manual lifting of the cutting blade in traditional devices, reducing manual intervention, and avoiding delays in production due to manual reset.

[0016] Furthermore, the top of the gantry frame is rotatably perforated by several bolts, all of which are threadedly connected to the top surface of the cutting blade.

[0017] In this technical solution, the bolt connection structure makes it easier to disassemble and assemble the cutting blade. When the cutting blade is worn or needs to be replaced to adapt to different fabrics, there is no need to make complicated modifications to the device, simplifying maintenance operations, shortening replacement time, avoiding interruption of the cutting process due to blade problems, and ensuring continuous and stable production.

[0018] Furthermore, two insertion holes are symmetrically opened on one side of the surface of the processing table. A second spring is installed at the bottom of the inner cavity of each of the two insertion holes, and a matching connecting post is slidably inserted into each of the two insertion holes. The top ends of the two second springs are respectively connected to the bottom ends of the two connecting posts. A pressure plate is fixedly connected between the top ends of the two connecting posts. When the pressure plate is attached to the surface of the processing table, the second spring is in a stretched state.

[0019] In this technical solution, the pressure plate can stably hold the curtain fabric during cutting, preventing the fabric from shifting and causing uneven cutting edges, and the second spring can adapt to the holding requirements of fabrics of different thicknesses, without the need for manual pressure adjustment.

[0020] Furthermore, connecting plates are fixedly connected to both sides of one end of the processing table, and connecting grooves are provided on both connecting plates. A connecting shaft is provided between the two connecting grooves, and an unwinding roller is fixedly connected to the outside of the connecting shaft.

[0021] In this technical solution, the curtain fabric can be continuously unrolled and conveyed directly through the integrated unrolling roller, without the need for additional independent unrolling equipment.

[0022] Furthermore, an L-shaped baffle is fixedly connected to one end of each of the two connecting plates, and the two ends of the connecting shaft are limited between the two L-shaped baffles to prevent the unwinding roller from rotating out of the connecting groove.

[0023] In this technical solution, the L-shaped baffle limits the connecting shaft, preventing the unwinding roller from detaching from the connecting groove during rotation, thus avoiding production interruptions caused by the easy detachment of the traditional unwinding structure.

[0024] Furthermore, a ratchet is fixedly connected to the outer side of the connecting shaft between the L-shaped baffle and the connecting plate on the same side, and a check pawl is rotatably connected to the L-shaped baffle below the ratchet, and the check pawl engages with the ratchet.

[0025] In this technical solution, the engagement of the ratchet and the anti-reverse pawl can prevent the unwinding roller from reversing, thus avoiding the fabric from becoming loose or piled up due to reversal. This ensures stable fabric conveying tension, which reduces positional deviation during fabric conveying and avoids cutting size deviation caused by the reversal of the unwinding roller.

[0026] Furthermore, guide grooves are provided at opposite ends of the two connecting plates between the unwinding roller and the processing table side end. Guide blocks are slidably connected in the two guide grooves. A rotating shaft is rotatably connected between the two guide blocks. A tensioning roller is fixedly connected to the outside of the rotating shaft. A third spring is fixedly connected between the top of the two guide blocks and the top of the inner cavity of the two guide grooves, respectively.

[0027] In this technical solution, the tension roller and the third spring can automatically adapt to the fabric conveying tension. Through the sliding adjustment of the guide block and the guide groove, the fabric is always kept flat and taut, avoiding fabric wrinkles and deviations caused by uneven tension in traditional conveying. The flat fabric conveying can further improve the cutting accuracy and ensure the uniformity of product specifications.

[0028] The beneficial effects of this utility model are:

[0029] 1. This utility model uses the sliding cooperation between the slider and the groove, and the abutment and locking of the fixing bolt, to push the gantry frame along the fixing strip to adjust the cutting position without the need to disassemble or modify the positioning components with tools such as wrenches. This solves the problem of cumbersome and time-consuming equidistant size adjustment in traditional devices. At the same time, the sliding fit between the T-shaped slider and the T-shaped limiting groove ensures the accurate sliding of the gantry frame, reduces the cutting size deviation caused by human operation error, and ensures the uniformity of the curtain fabric cutting specifications.

[0030] 2. This utility model prevents the unwinding roller from reversing by engaging the ratchet and the anti-return pawl, thus avoiding the fabric from becoming loose or piled up due to reversal. It ensures stable fabric conveying tension, which reduces positional deviation during fabric conveying and avoids cutting size deviation caused by unwinding roller reversal.

[0031] 3. This utility model can automatically adapt to the fabric conveying tension by using a tension roller in conjunction with a third spring. Through the sliding adjustment of the guide block and guide groove, the fabric is always kept flat and taut, avoiding fabric wrinkles and deviations caused by uneven tension in traditional conveying. The flat fabric conveying can further improve cutting accuracy and ensure product specifications are consistent. Attached Figure Description

[0043] Example 1:

[0044] like Figure 1-2 and Figure 4-5 As shown, this utility model provides an equidistant cutting device for curtain fabric production, including a processing table 1 and a cutting mechanism disposed outside the processing table 1 for equidistant cutting of curtain fabric. The cutting mechanism includes:

[0045] Two fixing strips 2 are respectively fixed to the two ends of the processing table 1. A sliding groove 21 is opened on one side of each fixing strip 2, and a slider 26 is slidably assembled in each sliding groove 21.

[0046] The gantry frame 23 has a cutting blade 3 installed on its inner top and limit grooves 25 opened at both ends of its inner side. The outer ends of the two sliders 26 extend into the corresponding limit grooves 25 and slide with the limit grooves 25.

[0047] Two rectangular holes 9 are respectively opened on the outer side walls at both ends of the gantry frame 23, and each of the rectangular holes 9 is connected to the inner cavity of the corresponding limiting groove 25.

[0048] Two fixing bolts 91 are respectively inserted into the corresponding rectangular holes 9, and each fixing bolt 91 passes through the corresponding slider 26 and abuts against the inner cavity of the slide groove 21, and the fixing bolt 91 is threadedly connected to the corresponding slider 26;

[0049] The inner cavity of the slide groove 21 is T-shaped, the shape of the slider 26 is T-shaped, and the slider 26 is adapted to the inner cavity of the slide groove 21 to improve the stability of the slider 26 sliding in the slide groove 21, thereby improving the stability of the gantry frame 23 sliding.

[0050] When adjusting the cutting position, first loosen the fixing bolt 91 to release the lock on the slider 26, and push the gantry 23 to slide along the slide groove 21 of the fixing strip 2. After adjusting to the target cutting position, tighten the fixing bolt 91 so that it passes through the slider 26 and abuts against the inner cavity of the slide groove 21, thereby locking and fixing the gantry 23. This eliminates the need to disassemble the positioning components with tools such as wrenches. The equidistant adjustment can be completed in just three steps: loosening the bolt, adjusting, and fixing. This avoids the cumbersome and time-consuming traditional adjustment. At the same time, the double sliding fit between the slider 26 and the slide groove 21 and the limiting groove 25 can accurately constrain the sliding trajectory of the gantry 23, reduce the positional deviation when manually pushed, and thus avoid inconsistent cutting dimensions due to operational errors, ensuring uniform specifications of the curtain fabric.

[0051] Both of the fixing strips 2 have scale lines 22 engraved on their surfaces.

[0052] When adjusting the position of the gantry 23, the operator can directly observe the scale line 22 on the surface of the fixing strip 2. According to the required cutting width, the gantry 23 is slid to the corresponding scale value. There is no need to repeatedly mark and position it with measuring tools such as tape measures. The scale line 22 provides an intuitive size reference, saving the steps of repeated measurement and marking. This not only shortens the adjustment time, but also avoids reading errors or marking deviations that may occur when marking manually. It helps to quickly and accurately switch between different width cutting specifications and improves product consistency.

[0053] The top of the inner cavity of each of the two limiting grooves 25 is fixedly connected to a first spring 24, and the bottom ends of the two first springs 24 are fixedly connected to the two sliders 26 respectively. The elastic force of the first spring 24 is greater than the sum of the weight of the gantry frame 23 and the cutting blade 3, which is used to ensure that the cutting blade 3 can automatically reset after it moves down to cut the curtain fabric.

[0054] During cutting, the gantry 23 is pressed down, causing the cutting blade 3 to move down to cut the curtain fabric. During this process, the first spring 24 in the limiting groove 25 is compressed. After cutting is completed, the gantry 23 is released. Because the elastic force of the first spring 24 is greater than the sum of the weights of the gantry 23 and the cutting blade 3, the first spring 24 will automatically extend and reset, causing the gantry 23 and the cutting blade 3 to rise back to their initial positions. This eliminates the need for manual lifting of the cutting blade 3, reducing manual intervention and avoiding production delays caused by untimely manual reset. At the same time, the spring reset process is stable and controllable, ensuring that the cutting blade 3 returns to a fixed position after each reset, preventing the cutting blade 3 from shifting and affecting the dimensional accuracy of subsequent cuts, and further ensuring uniform cutting specifications.

[0055] The top of the gantry 23 is rotatably connected by a number of bolts 31, and all of the bolts 31 are threadedly connected to the top surface of the cutting blade 3.

[0056] When the cutting blade 3 is worn and needs to be replaced, or when a special blade needs to be replaced to adapt to different fabrics, simply loosen the bolt 31 on the top of the gantry frame 23 to remove the old cutting blade 3 from the inside of the gantry frame 23. When installing the new cutting blade 3, align the bolt 31 holes and tighten the bolt 31 to fix the cutting blade 3. There is no need to make complicated disassemblies to the entire gantry frame 23. The blade can be installed and removed simply by loosening and tightening the bolt 31, which shortens the blade replacement time, avoids interruption of the cutting process due to troublesome blade maintenance, and ensures continuous and stable production.

[0057] Two insertion holes 43 are symmetrically opened on one side of the surface of the processing table 1. A second spring 42 is installed at the bottom of the inner cavity of each of the two insertion holes 43, and a matching connecting post 41 is slidably inserted into each of the two insertion holes 43. The top ends of the two second springs 42 are respectively connected to the bottom ends of the two connecting posts 41. A pressure plate 4 is fixedly connected between the top ends of the two connecting posts 41. When the pressure plate 4 is attached to the surface of the processing table 1, the second spring 42 is in a stretched state.

[0058] Before cutting, lift the pressure plate 4 upwards, place the curtain fabric in, and then release the pressure plate 4. When the pressure plate 4 is attached to the processing table 1, the second spring 42 is in a stretched state, and the spring will generate a downward rebound force. Through the connecting column 41, the pressure plate 4 is driven to press tightly against the fabric surface. When the fabric thickness is different, the connecting column 41 will slide up and down along the insertion hole 43, and the second spring 42 will extend and retract accordingly, automatically adapting to the fabric thickness and adjusting the holding force. Thus, the stable holding of the pressure plate 4 can limit the fabric from shifting during the cutting process, avoiding uneven cutting edges due to shifting. At the same time, the adaptive pressure adjustment of the second spring 42 can adapt to different fabric thicknesses without manual adjustment of the holding force, further improving the cutting regularity.

[0059] Example 2:

[0060] like Figure 1 and 3 As shown, both sides of one end of the processing table 1 are fixedly connected to connecting plates 5. Each of the two connecting plates 5 has a connecting groove. A connecting shaft 52 is provided between the two connecting grooves. An unwinding roller 51 is fixedly connected to the outside of the connecting shaft 52.

[0061] The rolled curtain fabric is placed on the unwinding roller 51. During cutting, as the fabric is fed to the processing table 1, the unwinding roller 51 rotates synchronously around the connecting shaft 52, continuously releasing the fabric. The connecting shaft 52 is mounted on the connecting plate 5 through the connecting grooves at both ends, ensuring that the unwinding roller 51 rotates stably. Thus, the integrated unwinding roller 51 eliminates the trouble of configuring an additional independent unwinding device and avoids the poor fabric feeding connection caused by the separation of the unwinding device and the cutting device in traditional production.

[0062] An L-shaped baffle 6 is fixedly connected to one end of each of the two connecting plates 5. The two ends of the connecting shaft 52 are limited between the two L-shaped baffles 6 to prevent the unwinding roller 51 from rotating out of the connecting groove.

[0063] When the unwinding roller 51 rotates around the connecting shaft 52, both ends of the connecting shaft 52 are always between the L-shaped baffles 6 on the outside of the connecting plate 5. The L-shaped baffles 6 can prevent the connecting shaft 52 from coming out of the connecting groove along the axial direction, thereby preventing the unwinding roller 51 from coming off the device, further avoiding production interruption caused by the unwinding roller 51 accidentally coming off when it rotates, and ensuring the stable operation of the unwinding process.

[0064] A ratchet 7 is fixedly connected to the outer side of the connecting shaft 52 between the L-shaped baffle 6 and the connecting plate 5 on the same side. A check pawl 71 is rotatably connected to the L-shaped baffle 6 below the ratchet 7, and the check pawl 71 engages with the ratchet 7.

[0065] When the unwinding roller 51 is unwinding normally, the connecting shaft 52 drives the ratchet 7 to rotate in the forward direction. The check pawl 71 rotates around the L-shaped baffle 6 under the push of the ratchet 7 teeth, and does not obstruct the rotation of the ratchet 7. When the unwinding roller 51 tends to reverse due to external force, the ratchet 7 rotates in the reverse direction. The check pawl 71 will be locked into the ratchet 7 teeth under its own weight or elastic force, preventing the ratchet 7 from continuing to rotate in the reverse direction, thereby preventing the unwinding roller 51 from reversing. This avoids the unwinding roller 51 from reversing and causing the released fabric to become loose and piled up, ensuring stable tension during the fabric conveying process. Stable tension can reduce the cutting position deviation caused by the looseness and offset of the fabric, further improving the consistency of the cutting size.

[0066] The two connecting plates 5 between the unwinding roller 51 and the side end of the processing table 1 each have a guide groove 8 at one end. A guide block 81 is slidably connected in each of the two guide grooves 8. A rotating shaft 83 is rotatably connected between the two guide blocks 81. A tension roller 84 is fixedly connected to the outside of the rotating shaft 83. A third spring 82 is fixedly connected between the top of each of the two guide blocks 81 and the top of the inner cavity of each of the two guide grooves 8.

[0067] When the curtain fabric is conveyed from the unwinding roller 51 to the processing table 1, the tensioning roller 84, under the elastic force of the third spring 82 (the spring applies downward pressure to the tensioning roller 84 through the guide block 81), presses tightly against the fabric surface. When the fabric conveying tension increases, the fabric will push the tensioning roller 84 upward, causing the guide block 81 to slide upward along the guide groove 8, and the third spring 82 will be compressed. When the tension decreases, the spring stretches and causes the guide block 81 to move downward, and the tensioning roller 84 presses the fabric again. Through the continuous pressing of the tensioning roller 84 and the adaptive adjustment of the third spring 82, the fabric can always be kept in a flat and taut state, avoiding fabric wrinkles and deviations caused by uneven tension in traditional conveying. The flat fabric conveying allows the cutting blade 3 to accurately act on the preset cutting position, further improving the cutting accuracy and ensuring the uniformity of the curtain fabric specifications.

[0068] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
