Description

Technical Field

[0001] The utility model relates to the field of cutting, and more specifically, to a trimming and winding machine for the production of sofa fabrics. Background Technique

[0002] A trimming and winding machine is a mechanical device specifically used for winding materials and cutting the edges of materials during the winding process. During the production of sofa fabrics, a trimming and winding machine is used to wind the processed fabrics and cut off the frayed edges during the winding process to make the appearance of the fabrics better.

[0003] Most of the cutting mechanisms of the existing trimming and winding machines are fixed in position using multiple bolts. When adjusting the relative position of the cutting knife, multiple bolts need to be loosened and then the relative position of the cutting knife is adjusted. After the adjustment is completed, the multiple bolts are fixed again. The process is relatively cumbersome and not convenient enough.

[0004] Based on the above, the purpose of the present utility model is to provide a trimming and winding machine for the production of sofa fabrics to solve the above problems. Content of the Utility Model

The present utility model is provided with an installation roller, and an installation block is slidably arranged on the installation roller. An installation ring and a circular knife are arranged on the installation block. Limiting blocks and a driving mechanism for driving the limiting blocks to move are slidably arranged on both sides of the installation block. A limiting rack cooperating with the limiting blocks is also arranged inside the installation roller. The user can drive the limiting blocks to separate from the rack through the driving mechanism to adjust the position of the tool. After the adjustment is completed, the driving mechanism is used to drive the limiting blocks and the rack to engage, so that the position of the tool on the installation roller cannot shift any more, making the adjustment of the tool position more convenient.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: A trimming and winding machine for the production of sofa fabrics, including an installation frame, several guiding rollers, a winding roller and a trimming component are arranged on the installation frame.

[0025] A trimming and winding machine for producing sofa fabrics, as Figures 1 - 5 shown, includes a mounting frame 1. A plurality of guide rollers 2, winding rollers 3 and trimming assemblies are provided on the mounting frame 1. The guide rollers and the winding rollers are both rotatably connected to the mounting frame. The trimming assembly includes a mounting roller 4. Scale marks are printed or machined on the mounting roller 4. The mounting roller 4 is rotatably connected to the mounting frame 1. A mounting groove 5 and a cavity are formed on the mounting roller 4. Limiting racks 7 are fixedly connected to both sides of the cavity. Mounting blocks 8 are slidably connected to both sides of the mounting groove 5. Limiting blocks 9 are slidably connected to both sides of the mounting blocks 8. A plurality of limiting teeth that cooperate with the limiting racks 7 are formed on the limiting blocks 9. A driving assembly for driving the two limiting blocks 9 to move is provided on the mounting blocks 8. A mounting ring 10 is sleeved on the mounting roller 4. The mounting ring 10 is detachably connected to the mounting block 8 by tools such as bolts. A circular knife 11 is detachably connected to the mounting ring 10 by fasteners such as bolts.

[0026] Furthermore, the driving assembly includes a bidirectional lead screw 12 rotatably connected to the mounting block 8. Inner hexagon or outer hexagon driving structures are formed at both ends of the bidirectional lead screw, and the bidirectional lead screw 12 can be rotated by a corresponding wrench. Slide seats 13 are threadedly connected to both the left-handed thread section and the right-handed thread section of the bidirectional lead screw 12. Driving rods 14 are provided on both sides of the slide seats 13, and one ends of the driving rods 14 are rotatably connected thereto. The other ends of the two driving rods 14 are respectively rotatably connected to the two limiting blocks 9.

[0027] Further, a support roller 15 is provided at the lower end of the installation roller 4. The support roller 15 is rotatably connected to the installation frame 1. A collection box is fixedly connected to the lower end of the support roller. The collection box can collect the cut waste materials, facilitating subsequent cleaning.

[0028] Further, a clamping portion 16 is formed on the limiting rack 7, and a clamping groove 17 for inserting the clamping portion 16 is formed on the inner wall of the installation groove.

[0029] Further, a first installation portion 18 is rotatably connected to one side of the installation frame 1. An electric push rod 19 is installed on the other side of the installation frame 1. A second installation portion 20 is rotatably connected to the extending end of the electric push rod 19. A through groove for inserting, moving, and rotating the second installation portion 20 is formed on the installation frame 1. Plugging portions 21 are fixedly connected to both the first installation portion 18 and the second installation portion 20. The shape of the plugging portion 21 is the same as the cross-section of the installation groove and the clamping groove 17.

[0030] Further, a smoothing mechanism 22 is installed on the installation frame 1. The smoothing module can smooth the wrinkles on the fabric. The smoothing mechanism consists of two relatively rotating smoothing rollers.

[0031] Working principle: When it is necessary to wind and trim the edges of the sofa fabric, the user can drive the sliding seats 13 on both sides to move away from each other by rotating the bidirectional lead screw 12, and then drive the limiting blocks 9 on both sides to approach each other through the driving rod 14 until the limiting teeth on both sides drive the limiting teeth to retract into the installation block 8. At this time, the installation block 8 can be pushed to move along the track of the installation groove 5, and then the position of the circular knife 11 can be adjusted as required. The scale marks can assist the user in controlling the distance between the two circular knives 11.

[0032] After the position of the circular knife 11 is adjusted, reverse-rotate the bidirectional lead screw 12, and then drive the limiting blocks 9 on both sides to extend until the limiting teeth are inserted into the two limiting racks 7 and mesh with them, so that the position of the circular knife 11 can no longer shift. Then pass the sofa fabric through a plurality of guide rollers 2, the smoothing assembly, the installation roller 4 and then connect it to the winding roller 3.

The smoothing roller in the smoothing assembly, the installation roller 4 and the winding roller 3 can be driven to rotate by a motor and a gear transmission assembly or a pulley transmission assembly. This is a mature existing technology and will not be elaborated here.

[0033] When maintenance, repair or replacement of the installation roller 4 or the circular knife 11 is required, the second installation part 20 is driven by the electric push rod 19 to move away from the installation roller 4 until the insertion part 21 on this side is separated from the installation roller 4. At this time, the user can remove the installation roller 4 or replace the circular knife 11. After the repair or replacement is completed, one side of the installation roller 4 is moved closer to the first installation part 18 until the insertion part 21 on this side is inserted into the installation groove 5 and the clamping groove of the installation roller 4. Then, the other side of the installation roller 4 is oriented towards the second installation part 20, and the second installation part 20 is driven by the electric push rod 19 to move closer to the installation roller 4 until the insertion part 21 on this side is inserted into the installation roller 4 and the installation roller is clamped by the first installation part and the second installation part on both sides. With such a setting, the disassembly of the installation roller 4 becomes more convenient.
