Description

Technical Field

[0001] This utility model relates to the field of tenter frame technology, specifically a tenter frame device for polyester double-layer gradient structure filter media. Background Technology

[0002] The tenter frame is a crucial step in textile dyeing and finishing. Through the effects of temperature, tension, and time, it helps fabrics achieve stable dimensions, the desired width, a smooth appearance, and certain special properties. After the fabric has undergone high-temperature setting in the setting oven and passed through a cooling zone, it typically still retains a residual temperature of 40-60°C when exiting the machine. At this temperature, both synthetic and natural fibers retain a degree of plasticity. Therefore, a fabric stacking device is usually installed at the end of the tenter frame. This device flings the fabric into a loose "Z"-shaped stack, allowing the fabric to hang naturally and without pressure in the stacking cart.

[0003] For example, the utility model patent with publication number CN218621425U discloses a fabric spreading device and a tenter frame, which achieves high spreading efficiency by using a fast swinging speed of the swing arm.

[0004] However, in the above technical solutions, the fabric swaying device of the tenter frame cannot adjust the swing amplitude and frequency according to the fabric output speed and the size of the stacking cart, which leads to the fabric being stacked and squeezed, causing the fabric edges to curl, wrinkle, or even be damaged.

[0016] Beneficial effects:

[0017] 1. In this utility model, the extension and retraction of the speed-regulating cylinder can press the transmission belt with the contact wheel, causing it to be concave.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] The embodiment of the utility model provides a tenter setting device for polyester double-layer gradient structure filter materials, as Figure 1-2 shown, which includes a tenter body. A fixing frame 1 is arranged at the end of the tenter body. A distributing frame 2 is rotatably installed on the fixing frame 1. The distributing frame 2 includes a distributing rod 21, a cloth outlet frame 22 and a plurality of guide rollers 23. A swing shaft 3 is rotatably installed at the upper end of the fixing frame 1. The top of the distributing rod 21 is connected to the swing shaft 3. The cloth outlet frame 22 is arranged on the lower side of the distributing rod 21. Two guide rollers 23 are arranged and rotatably installed on the cloth outlet frame 22 in parallel. A gap for the filter material to pass through is arranged between the two guide rollers 23.

[0026] As Figure 2 shown, a driving mechanism is arranged between the distributing rod 21 and the fixing frame 1. The driving mechanism includes a driving motor 4, a driving shaft 5, an eccentric wheel 6, a swing connecting rod 7 and a speed-changing component;

[0027] An installation cross beam 8 is arranged at the top of the fixing frame 1. The driving motor 4 is fixed on the lower side of the installation cross beam 8. The driving shaft 5 is rotatably installed on the fixing frame 1. Two eccentric wheels 6 are arranged and fixed at both ends of the driving shaft 5 respectively. An eccentric shaft rod 9 is arranged on the outer side of the eccentric wheel 6;

[0028] An installation groove is formed on the distributing rod 21. A lifting motor 10 is fixed in the installation groove. The output end of the lifting motor 10 is connected with a driving screw rod 11. The driving screw rod 11 is rotatably installed in the installation groove. A lifting slider 12 is slidably installed on the installation groove. The middle part of the lifting slider 12 is threadedly sleeved on the driving screw rod 11. A sliding shaft rod 13 is arranged on the front side of the lifting slider 12;

[0029] Both ends of the swing connecting rod 7 are respectively rotatably connected to the eccentric shaft rod 9 and the sliding shaft rod 13. By rotating the lifting motor 10, the height of the sliding shaft rod 13 on the distributing rod 21 can be adjusted through threaded cooperation, so that the swing amplitude of the distributing rod 21 can be changed, so that the filter cloth can be adapted to the stacking size of the cloth stacking vehicle, and the filter cloth is stacked in a Z shape, avoiding that the swing amplitude is greater than the cloth width, and the edge of the filter cloth will hit the side wall of the cloth stacking vehicle and then be forcibly wrinkled and stuffed in, resulting in curling and wrinkling of the cloth edge, or even damage to the cloth edge, or the swing amplitude is much smaller than the cloth width, and the cloth will be stacked in a "zigzag" shape instead of a "Z" shape, and the middle part will be suspended, and it cannot be smoothly folded layer by layer, easily causing uneven phenomena such as too high stacking in the middle and collapse on both sides, which is very untidy and also easy to cause pulling during subsequent cloth pulling.

[0030] As Figure 3-4 shown, the speed-changing component includes a fixed pulley 14, a sliding pulley 15, a transmission belt 16, a speed-regulating cylinder 17 and a contact wheel 18;

[0031] The fixed pulley 14 is fixed to the output end of the drive motor 4;

[0032] The sliding pulley 15 includes a sliding sleeve 151, a fixed guide plate 152, a moving guide plate 153, and a compression spring 154. The outer wall of the drive shaft 5 has several spline grooves, and the inner wall of the sliding sleeve 151 has several spline blocks. The spline blocks slide in conjunction with the spline grooves. The sliding sleeve 151 is slidably fitted onto the drive shaft 5, allowing it to slide left and right within the spline grooves. This ensures that the centerline of the sliding pulley 15 is always aligned with the fixed pulley 14. The fixed guide plate 152 is fixed to one end of the sliding sleeve 151. The outer wall of the sliding sleeve 151 is provided with a guide groove, and the inner wall of the moving guide plate 153 is provided with a guide block that slides and cooperates with the guide groove. The guide plate is slidably sleeved on the sliding sleeve 151. The fixed guide plate 152 and the moving guide plate 153 are provided with opposing transmission cone surfaces. The two transmission cone surfaces are combined to form a transmission groove that cooperates with the transmission belt 16. The end of the sliding sleeve 151 away from the fixed guide plate 152 is provided with a support ring 19. The two ends of the compression spring 154 abut against the support ring 19 and the moving guide plate 153 respectively.

[0033] The transmission belt 16 is sleeved and connected between the fixed pulley 14 and the sliding pulley 15;

[0034] The speed regulating cylinder 17 is vertically fixed to the rear side of the mounting beam 8 and positioned directly above the transmission belt 16. The output end of the speed regulating cylinder 17 is provided with a mounting frame, and the abutting wheel 18 is rotatably connected to the mounting frame. The abutting wheel 18 abuts against the middle of the transmission belt 16.

[0035] Through the above technical solution, the extension of the lifting cylinder can cause the contact wheel 18 to move downward and squeeze the transmission belt 16, causing the transmission belt 16 to be concave downward. With the fixed distance between the fixed pulley 14 and the sliding pulley 15, the pressure of the transmission belt 16 on the transmission cone surface of the moving guide plate 153 is increased, and the moving guide plate 153 slides towards the side of the fixed guide plate 152, increasing the distance between the transmission grooves. The transmission belt 16 slides towards the axial direction of the sliding pulley 15, thereby changing the transmission radius of the transmission belt 16 and the sliding pulley 15. This can change the transmission ratio between the transmission motor and the drive shaft 5, thereby changing the synchronous matching of the swaying frequency and the cloth output speed of the swaying frame 2, controlling the length of the filter cloth in each swaying cycle, and avoiding wrinkling or collapse caused by suspended stacking.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
