Description

Technical Field

[0001] This utility model relates to the field of jacquard fabric production equipment, specifically to a pretreatment device for jacquard fabrics. Background Technology

[0002] Jacquard fabric is a type of fabric in which various patterns are formed through clever variations in the warp and weft weave during the weaving process. These patterns are woven into the fabric during the weaving process, and once the fabric is formed, the pattern cannot be changed.

[0003] To further understand the existing jacquard fabric pretreatment devices, a search revealed that Chinese Patent No. CN222455554U discloses a pretreatment device for jacquard fabrics, including sprocket 1, sprocket 2, sprocket 3, sprocket 4, a transmission chain, and a drive unit. The drive unit is fixed to the bottom of the frame, sprocket 1 is fixed to the end of the upper feed roller, sprocket 2 is fixed to the end of the lower feed roller, sprocket 3 is fixed to the end of the tension roller, and sprocket 4 is connected to the drive unit. The transmission chain is sequentially engaged with sprocket 1, sprocket 2, sprocket 3, and sprocket 4.

[0004] After exploration and analysis, the patent has the following drawbacks in actual use: Although the patent uses tension rollers to stably tension the jacquard fabric in conjunction with upper and lower feed rollers with set temperatures to ensure the flatness of the jacquard fabric surface, the elasticity of jacquard fabrics of different materials is different. The tension rollers in the patent are fixed in position, which means that when tensioning jacquard fabrics of different materials, they cannot be tensioned stably in a uniform manner, which reduces the surface flatness of the jacquard fabric after pretreatment. Utility Model Content

[0005] To address the technical problem that existing tensioning rollers have fixed positions, resulting in inconsistent and stable tensioning of jacquard fabrics of different materials and reduced surface smoothness of the pre-treated jacquard fabrics, this utility model provides a pre-treatment device for jacquard fabrics.

[0006] The technical solution adopted by this utility model is as follows: It includes a base, on which two sets of mounting plates are fixedly connected. A heating roller is rotatably mounted between the two sets of mounting plates. Each of the two sets of mounting plates has a sliding groove on its opposite side, and a slider is slidably mounted in each of the sliding grooves. A tension roller is rotatably mounted between the two sets of sliders. Jacquard fabric is provided on the outside of the heating roller and the tension roller. Mounting blocks are fixedly connected to each of the two sets of mounting plates on their opposite sides. A sliding seat is slidably connected to each mounting block. A connecting rod is fixedly connected between the two sets of sliding seats. An adjusting rod is movably arranged between the sliding seat and the slider. A driving mechanism is provided in one set of mounting blocks.

[0007] Furthermore, the drive mechanism includes a lead screw rotatably mounted in a set of mounting blocks, a rotating rod rotatably mounted in a set of mounting plates, and a turntable fixedly connected to one end of the rotating rod. A first bevel gear is fixedly mounted on the other end of the rotating rod, and a second bevel gear meshes with one side of the first bevel gear. The second bevel gear is fixedly connected to one end of the lead screw, and the lead screw is threadedly connected to the slide block.

[0008] The position of the tension roller is adjusted by adopting the above technical solution.

[0009] Furthermore, a limiting groove is provided on one side of the mounting plate, and a limiting block is slidably installed in the limiting groove. The limiting block is fixedly connected to the side of the slide block.

[0010] By adopting the above technical solution, the stability during the tension roller adjustment process is improved.

[0011] Furthermore, a set of mounting plates has several sets of fixing holes on one side, and the turntable has insertion holes. A fixing rod is inserted into the insertion holes, and the fixing rod is adapted to the fixing holes.

[0012] By adopting the above technical solution, the stability of the position of the tension roller after adjustment is improved.

[0013] Furthermore, the heating roller is hollow, and a connecting pipe is rotatably installed in a set of mounting plates. The connecting pipe is connected to the interior of the heating roller, and a connector is fixedly installed at one end of the connecting pipe. An installation groove is opened on the circumferential surface of the heating roller, and a steam nozzle is fixedly installed in the installation groove.

[0014] By adopting the above technical solution, steam is used to heat the jacquard fabric that has passed through the heating roller.

[0015] Furthermore, a drying roller is rotatably mounted between the two sets of mounting plates. The drying roller is hollow and has an air outlet on its circumferential surface.

[0016] By adopting the above technical solution, the moisture in the tensioned jacquard fabric is dried.

[0017] The beneficial effects of this utility model are: by using a heating roller in conjunction with a tensioning roller and a drying roller, the jacquard fabric is heated and tensioned to make its surface flat and smooth. The lead screw, in conjunction with a slide block, adjusting rod and slider, adjusts the position of the tensioning roller, thereby adjusting the tension force applied by the tensioning roller to the jacquard fabric, so as to meet the requirements of applying appropriate tension force to jacquard fabrics of different materials, ensuring the effect of heating and tensioning pretreatment of jacquard fabric, and improving the surface flatness of the pretreated jacquard fabric.

[0018] The turntable, in conjunction with the rotating rod, the first bevel gear, the second bevel gear, and the lead screw, facilitates the movement of the sliding block to adjust the position of the tension roller and the tension applied by the tension roller. The turntable, along with the insertion hole, fixing hole, and fixing rod, fixes the adjusted turntable, improving the stability of the adjusted tension roller, ensuring the tension and flatness of the jacquard fabric, and enhancing the stability of the device.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0029] To address the problems existing in the background art, this application proposes the following technical solution: A base 1 is included, on which two sets of mounting plates 2 are fixedly connected. A heating roller 3 is rotatably mounted between the two sets of mounting plates 2. Each set of mounting plates 2 has a sliding groove 4 on its opposite side, in which a slider 5 is slidably mounted. A tension roller 6 is rotatably mounted between the two sets of sliders 5. Jacquard fabric 7 is provided on the outside of the heating roller 3 and the tension roller 6. Mounting blocks 8 are fixedly connected to each of the two sets of mounting plates 2 on their opposite sides. A sliding seat 9 is slidably connected to each mounting block 8. A connecting rod 12 is fixedly connected between the two sets of sliding seats 9. An adjusting rod 10 is movably arranged between the sliding seat 9 and the slider 5. A driving mechanism is provided in one set of mounting blocks 8.

[0030] Jacquard fabric 7 passes sequentially over the surfaces of heating roller 3 and tension roller 6. Driven forward by an external traction device, the heating roller 3 heats the jacquard fabric 7 to facilitate subsequent tensioning. The tension roller 6 applies pressure to the jacquard fabric 7, ensuring a smooth and even surface. The bottom of adjusting rod 10 is rotatably connected to slide block 9, and the upper end is rotatably connected to slider 5. A drive mechanism moves slide block 9, which in turn moves adjusting rod 10. Adjusting rod 10 pushes or pulls slider 5 in groove 4, which in turn moves tension roller 6, thus adjusting its position to apply appropriate pressure to jacquard fabric 7 of different materials. This ensures the effectiveness of the heating and tensioning pretreatment of jacquard fabric 7, improves the surface smoothness of jacquard fabric 7, and enhances the practicality of the device.

[0031] To further explain, the drive mechanism includes a lead screw 11 rotatably mounted in a set of mounting blocks 8, a rotating rod 14 rotatably mounted in a set of mounting plates 2, and a turntable 13 fixedly connected to one end of the rotating rod 14. A first bevel gear 15 is fixedly mounted on the other end of the rotating rod 14. A second bevel gear 16 meshes with one side of the first bevel gear 15. The second bevel gear 16 is fixedly connected to one end of the lead screw 11. The lead screw 11 is threadedly connected to the slide block 9.

[0032] The turntable 13 drives the rotating rod 14 to rotate, the rotating rod 14 drives the first bevel gear 15 to rotate, the first bevel gear 15 drives the second bevel gear 16 to rotate, the second bevel gear 16 drives the lead screw 11 to rotate, the lead screw 11 pushes the slide 9 to move, and the slide 9 drives the tension roller 6 to move through the adjusting rod 10 and the slider 5, adjusting the tension force applied by the tension roller 6 to the jacquard fabric 7, thereby improving the applicability of the device.

[0033] To further explain, a limiting groove 17 is provided on one side of the mounting plate 2, and a limiting block 18 is slidably installed in the limiting groove 17. The limiting block 18 is fixedly connected to the side of the slide block 9.

[0034] The limiting block 18, together with the limiting groove 17, guides and limits the movement of the slide 9, preventing the slide 9 from flipping over when the screw 11 rotates, thus improving the stability of the slide 9 during movement and improving the smoothness of adjusting the tension of the tension roller 6.

[0035] Furthermore, a set of mounting plates 2 has several sets of fixing holes 20 on one side, and a turntable 13 has an insertion hole 19. A fixing rod 21 is inserted into the insertion hole 19, and the fixing rod 21 is adapted to the fixing hole 20.

[0036] After adjusting the tension roller 6 to the appropriate position, the fixing rod 21 is inserted into the insertion hole 19 and the fixing hole 20 to restrict the position of the turntable 13. This prevents the tension roller 6 from shifting due to insufficient self-locking of the thread between the lead screw 11 and the slide block 9, ensuring the tension and flatness of the jacquard fabric 7 and improving the stability of the device.

[0037] To further explain, the heating roller 3 is hollow, and a connecting pipe 22 is rotatably installed in a set of mounting plates 2. The connecting pipe 22 is connected to the interior of the heating roller 3. A connector 23 is fixedly installed at one end of the connecting pipe 22. An installation groove 24 is opened on the circumferential surface of the heating roller 3, and a steam nozzle 25 is fixedly installed in the installation groove 24.

[0038] Connector 23 is connected to an external steam generator (not shown in the attached figure) via a pipe. Steam enters the interior of the heating roller 3 through the connecting pipe 22, and is then sprayed onto the jacquard fabric 7 on the surface of the heating roller 3 through the steam nozzle 25 to heat the jacquard fabric 7 and improve the smoothness of the jacquard fabric 7.

[0039] Furthermore, a drying roller 26 is rotatably mounted between the two sets of mounting plates 2. The drying roller 26 is hollow and has an air outlet 27 on its circumferential surface.

[0040] The jacquard fabric 7 passes over tension roller 6 and then over drying roller 26 (as shown in the attached document). Figure 2As shown in the figure, one end of the drying roller 26 is also provided with a connecting pipe 22 and a connector 23. The connector 23 is connected to an external air duct (not shown in the figure). The flowing air enters the second bevel gear 16 and is then sprayed onto the jacquard fabric 7 on the surface of the drying roller 26 through the air outlet 27 to dry the steam adsorbed on the jacquard fabric 7, so as to avoid the moisture on the jacquard fabric 7 from damaging it and improve the practicality of the device. The heating roller 3, the tensioning roller 6 and the drying roller 26 are all driven by motors, which are not shown in the figure.

[0041] The specific operation is as follows: The jacquard fabric 7 is sequentially passed over the heating roller 3, tension roller 6, and drying roller 26. The jacquard fabric 7 is moved forward by an external traction device. The heating roller 3 heats the jacquard fabric 7, and the tension roller 6 applies a certain pressure to the jacquard fabric 7, making the surface of the jacquard fabric 7 smooth and flat after passing through the tension roller 6. The drying roller 26 dries the steam adsorbed on the jacquard fabric 7. During the pretreatment of different materials 7, the turntable 13 is rotated, causing the rotating rod 14 to rotate, which in turn drives the first bevel gear 15 to rotate. The first bevel gear 15 then drives... The second bevel gear 16 rotates, driving the lead screw 11 to rotate. The lead screw 11 pushes the slide block 9 to move, and the slide block 9 drives the adjusting rod 10 to move. The adjusting rod 10 pushes or pulls the slider 5 to move in the slide groove 4. The slider 5 drives the tension roller 6 to move, thereby adjusting the position of the tension roller 6. After the tension roller 6 is adjusted to a suitable position, the fixing rod 21 is inserted into the insertion hole 19 and the fixing hole 20 to restrict the position of the turntable 13, so that the tension roller 6 can apply appropriate pressure to jacquard fabrics 7 of different materials, ensuring the effect of heat tensioning pretreatment of jacquard fabrics 7.
