[0003] Traditional tensioning wheels and tensioning bolts require multiple tools and multiple people to work together, and the adjustment stroke has no rigid limit, which can easily lead to "over-adjustment" or "reverse loosening". Utility Model Content

[0004] The purpose of this invention is to provide a lateral tension adjustment mechanism to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lateral tension adjustment mechanism includes a fixed plate, an adjustment assembly, and a synchronous pulley assembly. A sliding groove 1 is provided on one side of the fixed plate, and a non-communicating sliding groove 3 is provided on the opposite side of the fixed plate at the position corresponding to the sliding groove 1. Adjustment grooves are provided on both the upper and lower sides of the sliding groove 1 along the length direction. The sliding groove 1 is connected to the sliding groove 3 through the adjustment groove.

[0007] The adjustment assembly includes a guide clamp, and a linear adjustment mechanism is provided on one side of the guide clamp. The linear adjustment mechanism is fixedly installed with the fixed plate. The guide clamp slides in the first slide groove and is driven to make linear motion by the linear adjustment mechanism. The synchronous wheel assembly includes a pressure cover, which slides in the third slide groove. The pressure cover is provided with locking bolts at two corresponding adjustment grooves. The locking bolts pass through the corresponding adjustment grooves and are threadedly connected to the guide clamp.

[0008] In a preferred embodiment of the present invention, the linear adjustment mechanism includes an adjustment block, one end of which is fixedly connected to the guide clamp block, and the other end of which is threadedly connected to an adjustment bolt.

[0021] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0022] Example:

[0023] Please refer to the example below. Figure 1-4 As shown, this embodiment provides a lateral tension adjustment mechanism, including a fixed plate 1, an adjustment assembly 2 and a synchronous wheel assembly 3. A sliding groove 102 is provided on one side of the fixed plate 1, and a non-communicating sliding groove 3 105 is provided on the opposite side corresponding to the position of the sliding groove 102. Adjustment grooves 101 are provided on both the upper and lower sides of the sliding groove 102 along the length direction. The sliding groove 102 is connected to the sliding groove 3 105 through the adjustment grooves 101.

[0024] The adjusting assembly 2 includes a guide clamp 204. A linear adjusting mechanism is provided on one side of the guide clamp 204. The linear adjusting mechanism is fixedly installed with the fixing plate 1. The guide clamp 204 is slidably disposed in the first slide groove 102 and is driven to make linear motion by the linear adjusting mechanism. The synchronous wheel assembly 3 includes a pressure cover 303. The pressure cover 303 is slidably disposed in the third slide groove 105. The pressure cover 303 is provided with locking bolts 304 at each of the two adjusting grooves 101. The locking bolts 304 pass through the corresponding adjusting grooves 101 and are threadedly connected to the guide clamp 204.

[0025] Specifically, such as Figure 1-2As shown, the difference between this adjustment mechanism and existing technologies lies in that it features sliding grooves 102 and 305 on the front and back of the fixed plate 1, respectively. Guide clamps 204 and pressure caps 303 are placed within sliding grooves 102 and 305, respectively, and their dimensions are matched to ensure that they can only move, not wobble, thus guaranteeing the installation accuracy of the parts. Furthermore, since sliding grooves 102 and 305 are not interconnected, locking bolts 304 are used to securely connect guide clamps 204 and pressure caps 303, thereby allowing the sliding grooves 102 and 305 to move freely. The remaining solid parts of the 05 and fixed plate 1 guide the guide clamp 204 and the pressure cover 303. During the guidance, the guide clamp 204 and the pressure cover 303 cannot be removed from the fixed plate 1. This structure provides structural technical support for the purpose of single-person adjustment. The guide clamp 204 is driven by the linear adjustment mechanism, which in turn drives the pressure cover 303 and the entire synchronous wheel assembly 3 to move, thereby realizing the single-person adjustment function of this adjustment mechanism. After the adjustment is completed, only the locking bolt 304 needs to be tightened. The guide clamp 204 and the pressure cover 303 together clamp the solid part of the fixed plate 1, thereby achieving fixation.

[0026] In summary, only one person needs to loosen the two locking bolts 304 on the front of the equipment and rotate the adjusting bolt 202 in both directions to drive the synchronous pulley assembly 3 to slide left and right through the adjusting component 2, and the synchronous belt can be tensioned or loosened in one step. The operation is quick and requires no assistance. Through the assembly relationship between the structures, there is no need to make fine adjustments or corrections to the positions of each component, which can truly achieve rapid adjustment and positioning, without loss of transmission efficiency, and is conducive to further improving production efficiency.

[0027] In a preferred embodiment of the present invention, the linear adjustment mechanism further includes an adjustment block 203, one end of which is fixedly connected to a guide clamping block 204, and the other end of which is threadedly connected to an adjustment bolt 202. A fixing seat 201 is sleeved on the outside of the adjustment bolt 202, and the fixing seat 201 is fixedly installed with the fixing plate 1.

[0028] In a preferred embodiment of the present invention, the fixed seat 201 has a T-shaped cross section, and the fixed plate 1 has an installation groove 104 near the slide groove 102. The fixed seat 201 is embedded in one side of the installation groove 104 and is fastened to the fixed plate 1 by bolts. The head of the adjusting bolt 202 is in the installation groove 104.

[0029] In a preferred embodiment of the present invention, the surface of the fixing plate 1 is further provided with a second slide groove 103 that connects the mounting groove 104, the first slide groove 102 and the third slide groove 105 in the transverse direction, and the adjusting block 203 is slidably disposed in the second slide groove 103.

[0030] In a preferred embodiment of the present invention, the adjusting block 203 has a hollow groove 205 in the middle along the length direction, and the end of the adjusting bolt 202 extends into the hollow groove 205.

[0031] Specifically, such as Figure 2-4 As shown, by loosening the locking bolt 304 between the guide clamp 204 and the pressure plate 303, the clamping of the two on the fixing plate 1 is released. By turning the adjusting bolt 202, the operator drives the adjusting block 203, which is threadedly connected to it, to drag the guide clamp 204 to move laterally, thereby realizing the adjustment function of this adjusting mechanism.

[0032] Meanwhile, to further improve the smoothness and accuracy of the movement of the guide clamp 204, a sliding groove 3 105 is added to guide the adjusting block 203, thereby further improving the accuracy of the positioning assembly structure. At the same time, by opening a hollow groove 205 in the middle of the adjusting block 203, the length of the threaded hole that needs to be opened at the end of the adjusting block 203 is reduced, thereby reducing the processing difficulty and improving the thread connection accuracy between the adjusting bolt 202 and the threaded hole. This effectively prevents the situation of jamming and interference between structures during the adjustment process, and effectively ensures the normal function of the mechanism.

[0033] In a preferred embodiment of the present invention, the synchronous pulley assembly 3 further includes a tensioning shaft 301, which is fixedly installed in the middle of the pressure cover 303, and at least one synchronous pulley 302 is connected to the surface bearing of the tensioning shaft 301.

[0034] The working principle of this lateral tension adjustment mechanism is as follows: After fixing the mechanism to the original synchronous belt mounting position...

[0035] First, loosen the locking bolt 304, then rotate the adjusting bolt 202 counterclockwise to make the guide clamp 204 slide along the grooves opened in the fixed plate 1. At the same time, the timing pulley 302 moves to the right to loosen the timing belt so that it can be removed.

[0036] After reinstalling the timing belt, rotate the adjusting bolt 202 clockwise. The guide clamp 204 moves to the left and pushes the timing pulley 302 to move to the left in sync. The timing belt is then tensioned. Finally, tighten the locking bolt to secure it and complete the adjustment.

[0037] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
