Description

Technical Field

[0001] This utility model relates to the field of tension roller technology, and specifically to a tension roller adjustment device. Background Technology

[0002] In the production process of automotive filter paper, the filter paper substrate needs to be coated with adhesive and then rolled into a roll. During this process, the filter paper needs to be tensioned to make it more stable during transportation and to make the wound filter paper roll tighter. In the existing technology, tension rollers are used for adjustment. Changing the position of the tension rollers can stretch the filter paper and thus increase the tension of the filter paper during transportation. However, in the existing technology, the tension rollers are fixed in a certain position by screws. When it is necessary to adjust the tension, the screws need to be loosened to change the position of the tension rollers, which is relatively fixed. Utility Model Content

[0003] The purpose of this invention is to provide a tension roller adjustment device to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tension roller adjusting device, comprising: a frame, on each side of the frame a first mounting base and a second mounting base fixedly connected, a guide rod provided between the first mounting base and the frame, a slide block slidably mounted on the guide rod, the two slide blocks being connected by a U-shaped frame, and a tension roller mounted on the two slide blocks, a partition plate located between the first mounting base and the slide block being provided on the frame, a lead screw threadedly connected to the partition plate, one end of the lead screw being connected to the U-shaped frame via a bearing, and the other end of the lead screw being fixedly connected to a throttle handle.

[0005] Furthermore, a reinforcing rib is fixedly connected to the frame, and the partition is fixedly connected to the top of the reinforcing rib.

[0006] Furthermore, a third mounting groove is provided on the slide block, and bearings are sleeved on both ends of the tension roller and placed in the third mounting groove. A third mounting cover covering the tension roller and sleeved on the bearings is connected to the top of the slide block by screws.

[0007] Furthermore, the first mounting base has a first mounting groove, in which a first guide roller with bearings at both ends is placed, and the top of the first mounting base is connected by screws to a first mounting cover that covers the bearings on the first guide roller.

[0008] Furthermore, a second mounting groove is provided on the second mounting base, and a second mounting cover is fixedly connected to the bottom of the second mounting base by screws. A second guide roller with bearings at both ends is provided between the second mounting cover and the second mounting groove.

[0009] Furthermore, filter paper is wrapped around the tension roller, the first guide roller, and the second guide roller.

[0010] The tension roller adjusting device provided by this utility model has the following advantages in the above technical solution:

[0011] This invention achieves the purpose of adjusting the position of the tension roller by rotating the lead screw, which causes the U-shaped frame to move closer to or away from the partition. By sliding the slide block on the guide rod, the two slide blocks are more stable when moving synchronously, which is more convenient than the prior art.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0024] Please see Figures 1-6 A tension roller adjusting device includes: a frame 1, a first mounting base 11 and a second mounting base 12 fixedly connected to each side of the frame 1, a guide rod 8 between the first mounting base 11 and the frame 1, a slide block 3 slidably mounted on the guide rod 8, the two slide blocks 3 being connected by a U-shaped frame 31, and a tension roller 5 mounted on the two slide blocks 3, a partition plate 131 located between the first mounting base 11 and the slide block 3 on the frame 1, a lead screw 4 threadedly connected to the partition plate 131, one end of the lead screw 4 being connected to the U-shaped frame 31 through a bearing, and the other end of the lead screw 4 being fixedly connected to a throttle 41.

[0025] Specifically, this utility model rotates the lead screw 4, causing the lead screw 4 to move the U-shaped frame 31 closer to or away from the partition 131, thereby achieving the purpose of adjusting the position of the tension roller 5. By sliding the slide block 3 on the guide rod 8, the two slide blocks 3 are more stable when moving synchronously, which is more convenient than the prior art.

[0026] Furthermore, a reinforcing rib 13 is fixedly connected to the frame 1, and a partition 131 is fixedly connected to the top of the reinforcing rib 13. The reinforcing rib 13 plays a role in strengthening the structural stability of the frame 1.

[0027] Furthermore, a third mounting groove 32 is provided on the slide block 3. Bearings are fitted on both ends of the tension roller 5 and placed in the third mounting groove 32. The top of the slide block 3 is connected by screws to a third mounting cover 51 that covers the tension roller 5 and covers the bearings. The bearings fitted on the ends of the tension roller 5 are pressed by the third mounting cover 51, thereby realizing the installation of the tension roller 5 without affecting the rotation of the tension roller 5.

[0028] Furthermore, a first mounting groove 111 is provided on the first mounting base 11, and a first guide roller 6 with bearings sleeved at both ends is placed in the first mounting groove 111. A first mounting cover 61 covering the bearings on the first guide roller 6 is connected to the top of the first mounting base 11 by screws. The bearings sleeved on the ends of the first guide roller 6 are pressed by the first mounting cover 61, thereby realizing the installation of the first guide roller 6 without affecting the rotation of the first guide roller 6.

[0029] Furthermore, a second mounting groove 121 is provided on the second mounting base 12, and a second mounting cover 71 is fixedly connected to the bottom of the second mounting base 12 by screws. A second guide roller 7 with bearings sleeved at both ends is provided between the second mounting cover 71 and the second mounting groove 121. The installation method is the same as that of the tension roller 5 and the first guide roller 6. The bearings sleeved on the ends of the second guide roller 7 are pressed by the second mounting cover 71 to realize the installation of the second guide roller 7 without affecting the rotation of the second guide roller 7.

[0030] Furthermore, filter paper 2 is wrapped around the tension roller 5, the first guide roller 6, and the second guide roller 7. The filter paper 2 is wound around the second guide roller 7, the tension roller 5, and the first guide roller 6 in sequence. The tension of the filter paper 2 can be changed by adjusting the distance between the tension roller 5 and the partition plate 131.

[0031] In this utility model, reference Figures 1 to 6 By gripping the throttle 41 and tightening the screw 4, the screw 4 causes the U-shaped frame 31 to move to the left, which in turn causes the slide 3 to move to the left on the guide rod 8, changing the tension of the filter paper 2. The screw 4 is externally fixed with the inner ring of the bearing, and the outer ring of the bearing is embedded in the U-shaped frame 31, which in turn causes the U-shaped frame 31 to move with the screw 4 in the left and right directions.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
