Description

Technical Field

[0001] This application relates to the field of battery die-cutting equipment technology, and in particular to a graduated adjustable lead screw device. Background Technology

[0002] In various industrial production and material handling fields, conveyor belt equipment, as one of the core components, undertakes the important task of continuous and stable material transport. The tension of the conveyor belt directly affects its operating performance and service life. If the tension is insufficient, the conveyor belt is prone to slippage, leading to reduced material transport efficiency and even equipment failure. If the tension is too high, it will accelerate the wear of the conveyor belt, shorten its service life, and increase the energy consumption of the equipment. Therefore, precise adjustment of the conveyor belt tension is crucial.

[0003] Currently, most common conveyor belt tension adjustment methods rely on manual experience for approximate adjustments, lacking precise quantitative methods. Operators typically observe the conveyor belt's operating status, such as for slippage or slackness, and manually adjust the tensioning device based on their personal experience. This method not only makes it difficult to guarantee adjustment accuracy, easily leading to over- or under-adjustment, but also involves a cumbersome and time-consuming adjustment process, failing to quickly respond to the dynamic needs of conveyor belt tension in actual production.

[0004] Furthermore, while some existing tension adjustment devices possess certain adjustment functions, their complex structure, inconvenient operation, and lack of intuitive adjustment feedback mechanisms make it difficult for operators to accurately determine the current adjustment amount and the actual tension of the conveyor belt. This, to some extent, increases the difficulty and cost of equipment maintenance and also affects the continuity and stability of production. Utility Model Content

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application. It is understood that the accompanying drawings are provided for reference and illustration only, and are not intended to limit this application.

[0035] Specifically, such as Figure 1 As shown, this application embodiment provides a scaled adjustable tension screw 120 device, which mainly includes an adjusting ruler 100 and a roller device 200. The adjusting ruler 100 is installed on the roller device 200. The roller device 200 is provided with a support frame 210 and a roller 220. The roller 220 is rotatably installed on the support frame 210. A conveyor belt 230 is sleeved on the roller 220. The function of the roller 220 in this application is to adjust the tension of the conveyor belt 230 so that the tension of the conveyor belt 230 on both sides of the roller 220 is kept balanced. This balance is maintained by adjusting the adjusting ruler 100.

[0036] Specifically:

[0037] In this embodiment, the adjusting ruler 100 is provided with a housing 110. A through groove 111 is provided inside the housing 110. A lead screw 120 is provided in the through groove 111. The lead screw 120 rotates in the through groove 111 and is threadedly connected to the housing 110, so that when the lead screw 120 rotates, it moves linearly relative to the housing 110. A driving member 130 is provided at one end of the lead screw 120. The position of the driving member 130 relative to the lead screw 120 is connected to the roller 220, and the driving member 130 is located on one side of the roller 220, so that the lead screw 120 is set perpendicular to the roller 220, which facilitates the lead screw 120 to push the roller 220.

[0038] The lead screw 120 is provided with a plurality of balls 140, and a spiral groove 122 is formed on the lead screw 120. The plurality of balls 140 are all located in the spiral groove 122, and the diameter of the cross section of the spiral groove 122 is equal to the diameter of the balls 140, so that the balls 140 fit perfectly into the spiral groove 122.

[0039] A limiting groove 150 is provided in the through groove 111 of the housing 110 corresponding to the position of the ball 140. The inner diameter of the limiting groove 150 is equal to the diameter of the ball 140, so that the ball 140 can be limited by the limiting groove 150 and the spiral groove 122, so that the ball 140 can move along the position of the limiting groove 150 and the spiral groove 122.

[0040] In the above, the movement of the ball 140 converts sliding friction into rolling friction, thereby significantly improving transmission efficiency, accuracy and load-bearing capacity, and enabling the lead screw 120 to move stably and linearly within the housing 110.

[0041] Since the ball 140 rolls on the lead screw 120, a drain tube 160 is provided on the housing 110 to facilitate the movement of the ball 140. The two ends of the drain tube 160 are located on both sides of the housing 110 and abut against the limiting groove 150 and the spiral groove 122. When the ball 140 moves to one end of the housing 110, the ball 140 slides into the drain tube 160 and slides back into the spiral groove 122 from the other end of the housing 110, so that the lead screw 120 is always connected to the housing 110 through the ball 140.

[0042] In the above, in order to facilitate the movement of the ball bearing 140 within the drainage tube 160, the inner diameter of the drainage tube 160 is larger than the diameter of the ball bearing 140.

[0043] Meanwhile, in this embodiment, a limiting member 170 is also provided. The limiting member 170 is located on the housing 110, specifically on the inner wall of the through groove 111. The limiting member 170 mainly provides a limiting pin 171. A limiting hole 112 is opened on the housing 110 at the position corresponding to the limiting pin 171. The limiting pin 171 is located in the limiting hole 112. A limiting spring 172 is provided in the limiting hole 112. One end of the limiting spring 172 abuts against the housing 110, and the other end of the limiting spring 172 abuts against the limiting pin 171, so that the limiting spring 172 abuts against the limiting pin 171. 72 pushes the limiting pin 171 towards the lead screw 120. A fixing hole 121 is provided on the lead screw 120 at the position corresponding to the limiting pin 171. The diameter of the fixing hole 121 is larger than the diameter of the cross-section of the limiting pin 171, so that when the lead screw 120 rotates to a certain position, one end of the limiting pin 171 is exactly located in the fixing hole 121. The limiting pin 171 fixes the lead screw 120 and prevents the lead screw 120 from continuing to move within the housing 110, thereby limiting the lead screw 120.

[0044] Furthermore, a scale element 180 is provided at one end of the housing 110. The scale element 180 is sleeved around the lead screw 120, and the rotation of the lead screw 120 drives the rotation of the scale element 180. The scale element 180 is connected to one end of the housing 110 for limiting. The scale element 180 allows the operator to intuitively observe the rotation angle and displacement of the lead screw 120, thereby achieving precise adjustment of the tension of the conveyor belt 230. The scale element 180 has clear scale markings. The operator only needs to rotate the lead screw 120 to the corresponding scale position according to the actual needs to achieve quick and accurate adjustment of the tension of the conveyor belt 230. This design not only improves the adjustment accuracy but also greatly simplifies the adjustment process, enabling the operator to easily meet the dynamic needs of the conveyor belt 230 tension in actual production.

[0045] In practical implementation, the idler roller device 200 is fixed by a support frame 210. Two support grooves 211 are laterally arranged on the support frame 210, and both ends of the roller 220 are located within these two support grooves 211, allowing the roller 220 to rotate stably. An adjusting ruler 100 is mounted on the support frame 210 and connected to the roller 220 via a drive component 130. When the tension of the conveyor belt 230 needs to be adjusted, the operator only needs to rotate the lead screw 120. The lead screw 120 can then move linearly within the through groove 111 of the housing 110, and the drive component 130 pushes the roller 220 to move, thereby adjusting the tension of the conveyor belt 230.

[0046] In summary, the graduated tension adjustment screw device provided by this utility model effectively solves the problems existing in the prior art by adopting the design of the threaded screw 120 and housing 110, the limiting groove 150 and the ball 140, the setting of the limiting component 170, and the setting of the graduated component 180. It improves the adjustment accuracy and stability of the tension of the conveyor belt 230, reduces the difficulty and cost of equipment maintenance, and provides a new, more efficient and reliable conveyor belt tension adjustment device for industrial production and material conveying.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
