Description

Technical Field

[0001] This utility model relates to the technical field of clamping roller equipment, specifically to a clamping roller spacing adjustment mechanism for a silicone flame retardant pad production line. Background Technology

[0002] Silicone flame retardant pads are protective materials used to improve battery safety. They are mainly made of liquid silicone. During the production process of silicone flame retardant pads, clamping rollers are used. The clamping rollers use the squeezing force generated between two rotating rollers to clamp the silicone flame retardant pads, thereby driving the silicone flame retardant pads forward.

[0003] During use, the gap between the two rotating rollers will increase due to vibration and friction, which will reduce the clamping effect. At the same time, silicone flame retardant pads of different thicknesses need to adjust the gap between the two rotating rollers through the clamping roller gap adjustment mechanism. The existing clamping roller gap adjustment mechanism uses a screw to directly push the rotating roller to adjust the gap. This method is time-consuming and laborious, and the locking effect is poor. It needs to be adjusted frequently during operation. Utility Model Content

Push column 24; The worm gear 21 and worm 20 can be rotatably mounted on the mounting frame 10. The worm gear 21 meshes with the worm 20. The worm gear 21 has a first through hole 22 at its center, and the inner wall of the first through hole 22 has an internal thread 23. The push column 24 has an external thread 25 on its periphery. The push column 24 is threadedly connected to the worm gear 21 through the internal thread 23 and the external thread 25, and one end of the push column 24 extends out of the first through hole 22 and abuts against the first mounting seat 13. The mounting frame 10 is provided with a guide column 34. The push column 24 has a guide groove 26 on its periphery that cooperates with the guide column 34 so that the push column 24 can only move along its own axial direction. By setting up the cylinder 14, worm 20, worm gear 21 and push column 24, the push column 24 is moved by the cooperation of the worm gear 21 and worm 20, so as to easily adjust the distance between the first roller 11 and the second roller 12 and solve the problem of time-consuming and laborious adjustment.

[0033] In this invention, there are two sets of adjustment components, which are located at both ends of the first rotating roller 11.

[0034] The worm gear 20 is equipped with a handwheel, which facilitates the rotation of the worm gear 20.

[0035] The mounting bracket 10 is also provided with a second mounting seat, which has a receiving cavity for accommodating the worm gear 21. The worm 20 extends into the receiving cavity and meshes with the worm gear 21. The two opposite side walls of the receiving cavity are provided with second through holes 33 for the pusher 24 to pass through. The second mounting seat includes a U-shaped body 30, a first side plate 31 and a second side plate 32. The first side plate 31 and the second side plate 32 are detachably mounted on opposite sides of the U-shaped body 30. The U-shaped body 30, the first side plate 31 and the second side plate 32 form a receiving cavity. The worm 20 is rotatably mounted on the first side plate 31 and the second side plate 32 through bearings. The detachable design facilitates maintenance.

[0036] The guide post 34 is disposed on the inner side wall of the second through hole 33 and extends into the guide groove 26; the second mounting base has a third through hole 35 that communicates with the second through hole 33, and the guide post 34 is inserted into the third through hole 35; by providing the third through hole 35, the guide post 34 can be quickly replaced, and when the guide post 34 is damaged, there is no need to replace the entire second mounting base, thus reducing the cost of use.

[0037] The second mounting base is also provided with a locking element 27 for locking the worm gear 20; by setting the locking element 27, the locking effect of the worm gear 20 can be further improved, and accidental contact during operation can be avoided.

[0038] It should be understood that the locking element 27 adopts a locking element 27 structure commonly used by those skilled in the art, and will not be described in detail here.

[0039] The first mounting base 13 is provided with a displacement detector 41 for detecting the distance between the first roller 11 and the second roller 12; a third mounting base 40 is provided on one side of the first mounting base 13, and the displacement detector 41 is mounted on the third mounting base 40; by setting the displacement detector 41, the distance between the first roller 11 and the second roller 12 can be quantified, which facilitates precise adjustment.

[0040] In this embodiment, the detection accuracy of the displacement detector 41 is 0.01 mm.

[0041] It should be understood that the displacement detector 41 is a displacement detector 41 structure commonly known to those skilled in the art, and will not be described in detail here.

[0042] The method of using this utility model is as follows: In use, the cylinder 14 drives the first rotating roller 11 and the second rotating roller 12 to separate, insert the silicone flame-retardant pad, and drive the cylinder 14 again to make the first rotating roller 11 and the second rotating roller 12 clamp the silicone flame-retardant pad. When adjustment is required, the handwheel is turned to make the worm gear 20 drive the worm wheel 21 to rotate, thereby pushing the push column 24 towards the third mounting base 40, changing the distance between the first rotating roller 11 and the second rotating roller 12. By checking the value displayed on the displacement detector 41, the desired distance can be precisely adjusted. After adjustment, the locking part 27 is used to lock the worm gear 20 to complete the adjustment.

[0043] This invention utilizes a cylinder 14, a worm gear 20, a worm wheel 21, and a pusher column 24. The worm wheel 21 and worm gear 20 work together to move the pusher column 24, easily adjusting the distance between the first roller 11 and the second roller 12. Compared to existing screw adjustment methods, this method offers easier, faster, and more efficient adjustment. The use of the worm wheel 21 and worm gear 20 for adjustment, along with their self-locking characteristics, avoids changes in the clamping roller distance due to vibration or other factors during use, improving reliability and eliminating the need for multiple adjustments, thus increasing work efficiency.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technical aspects of the present utility model shall still fall within the scope of the technical solution of the present utility model.
