Description

Technical Field

[0001] This utility model relates to the technical field of fabric drying devices, specifically to a drying device for a fabric laminating machine. Background Technology

[0002] After multi-layer fabric lamination, the adhesive between the fabric layers needs to be dried. Existing technology mainly uses a drying device to dry the laminated fabric. During drying, the fabric is conveyed from the laminating machine to the drying chamber, where it is dried by the high temperature inside the chamber. To extend the time the fabric stays in the drying chamber, existing drying chambers are equipped with several fabric guide rollers that guide the fabric in a serpentine conveyor. Since the thickness or number of layers of the laminated fabric varies, their drying requirements differ, so the time spent in the drying chamber needs to be controlled. If the time is too short, the drying is incomplete; if the time is too long, the drying efficiency is affected. Therefore, this utility model provides a drying device for a fabric laminating machine.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, a drying device for a fabric laminating machine includes: a frame 1, two fabric guide rollers 2 are arranged on the frame 1, and a drying box 3 is arranged between the two fabric guide rollers 2.

[0023] like Figure 2 As shown, the drying chamber 3 has an inlet and an outlet, and two sets of guide rollers 4 are installed inside it, with the two sets of guide rollers 4 positioned close to the inlet and outlet respectively. Preferably, both the inlet and outlet are located in the middle of the drying chamber 3.

[0024] Hot air mechanisms are installed at both the top and bottom of the drying oven 3. These mechanisms include a hot air box 5, which contains heating wires and a fan. The fan is located on the side of the heating wires furthest from the drying oven 3 to deliver hot air into the oven 3. The hot air box 5 has a diffused structure, wider at one end than the other, with the end closer to the drying oven 3 being relatively larger to facilitate hot air diffusion. A filter screen 15 is also installed inside the hot air box 5, positioned between the heating wires and the drying oven 3 to isolate the fabric from the heating wires.

[0025] like Figure 3 As shown, two partition plates 6 are installed inside the drying oven 3. The two partition plates 6 are respectively located close to the two opposite side walls of the drying oven 3, and an installation space is formed between them and the side walls.

[0026] Several movable guide rollers 7 are arranged between two partition plates 6. The movable guide rollers 7 are distributed vertically at intervals, and the shafts of the movable guide rollers 7 extend from the slots 8 opened on the partition plates 6 into the installation space. The movable guide rollers 7 at the top are at the same height, and the movable guide rollers 7 at the bottom are at the same height.

[0027] The end of the shaft of the movable guide roller 7 is provided with a sliding block 9, and the sliding block 9 has a threaded hole for threaded connection with the lead screw 10 provided in the installation space. The threads on the surfaces of two adjacent lead screws 10 are in opposite directions, so that two adjacent movable guide rollers 7 can move in different directions.

[0028] A first helical gear 11 is provided at the top of the lead screw 10. A second helical gear 12 is provided on one side of the first helical gear 11, perpendicular to and meshing with it. A drive rod 13, which rotates synchronously with the second helical gear 12, is inserted in the center of the second helical gear 12. One end of the drive rod 13 is connected to the drive motor 14. The drive motor 14 drives the drive rod 13 to rotate, the drive rod 13 drives the second helical gear 12 to rotate, the second helical gear 12 drives the first helical gear 11 to rotate, the first helical gear 11 drives the lead screw 10 to rotate, and the lead screw 10 drives the sliding block 9 to rise and fall. The moving guide roller 7 moves synchronously with the sliding block 9. Since the two adjacent moving guide rollers 7 are arranged vertically and move in opposite directions, the distance between the two moving guide rollers 7 can be adjusted by the drive motor 14, thereby changing the fabric transmission distance and adjusting the time the fabric stays in the drying chamber 3.

[0029] Among them, such as Figure 4 As shown, the guide rollers 4 include an upper roller 41 and a lower roller 42. The shafts of both the upper roller 41 and the lower roller 42 extend into the installation space through slots formed on the partition plate 6. Each shaft end of both rollers has a movable block 43 with a threaded hole for threaded engagement with a bidirectional lead screw 44 located within the installation space. The bidirectional lead screw 44 has two sets of reverse threads, which respectively engage with the two movable blocks 43. The bidirectional lead screw 44 is connected to a drive device located within the installation space. The drive device is a motor that rotates the bidirectional lead screw 44, causing the two movable blocks 43 to move in opposite directions, thus moving the upper and lower rollers closer together or further apart to change the distance between them and meet the needs of fabrics of different thicknesses.

[0030] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
