[0002] Currently, the transmission structures of laminating machines, slitting machines, and winding machines on the market generally use chains, synchronous belts, and belts to drive transmission wheels. Tension adjustment of these connecting components typically involves rotating an adjusting wheel on a mounting plate with slotted holes. The mounting plate is then secured to a mounting frame using screws or bolts passing through these holes. Adjusting the tension of the connecting component is achieved by adjusting the mounting plate's position on the mounting frame through the slotted holes, thereby changing the position of the adjusting wheel and adjusting the tension. However, this process is time-consuming and inefficient. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a rapid tension adjustment device that simplifies the transmission structure of a composite machine, enables quick and easy adjustment of belt tension, and improves work efficiency.

The adjustment disc is rotatably mounted on the mounting plate by inserting the first rotating shaft into the shaft hole. A second rotating shaft is eccentrically mounted on the first rotating shaft, and an adjustment wheel is mounted on the second rotating shaft. By eccentrically mounting the second rotating shaft, rotating the adjustment disc causes the first rotating shaft to rotate, thereby changing the position of the second rotating shaft and thus changing the position of the adjustment wheel, thereby adjusting the tension of the connecting component and solving the problem of low adjustment efficiency.

[0006] As a preferred embodiment, the distance between the centers of the first and second rotating shafts is 30-100 mm.

[0007] As a preferred embodiment, the adjustment disc is further provided with a first mounting hole, which is located on the edge of the end face of the adjustment disc.

The mounting plate is provided with a second mounting hole corresponding to the arc-shaped through hole. During assembly, the adjusting plate is mounted on the mounting plate by screwing screws or bolts through the arc-shaped through hole and connecting them to the second mounting hole.

[0009] As a preferred embodiment, the system also includes a drive motor, which is provided with a drive mounting bracket and is mounted on a mounting plate via the drive mounting bracket.

[0010] As a preferred embodiment, the drive mounting bracket has a protective cylinder with a clearance slot, and the output end of the drive motor drives the adjustment wheel through the clearance slot via a connector.

[0011] As a preferred embodiment, the protective cylinder extends radially outward at both ends to form a first mounting portion and a second mounting portion, respectively. The drive motor is mounted on the first mounting portion, and the second mounting portion is mounted on the mounting plate.

[0012] As a preferred embodiment, the second mounting part is provided with a plurality of third mounting holes, and the mounting plate is provided with a plurality of fourth mounting holes corresponding to the third mounting holes. The drive mounting bracket is mounted on the mounting plate by screws or bolts passing through the third mounting holes and connecting to the fourth mounting holes.

The drive motor drives and connects to the first adjusting wheel via a connector, and the driven wheel is driven and connected to the second adjusting wheel via a connector.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, by rotating the adjustment disc on the mounting plate and eccentrically setting the rotating shaft on the adjustment disc, the position of the second rotating shaft can be changed by rotating the adjustment disc, thereby changing the position of the adjustment wheel, thus realizing the adjustment of the tension of the connecting parts and improving work efficiency.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figure 1-4 As shown, this utility model discloses a tension quick adjustment device, including a mounting plate 10 and an adjustment disc 20. The adjustment disc 20 has a first rotating shaft 21 protruding from it. The mounting plate 10 has a shaft hole 11 corresponding to the first rotating shaft 21. The adjustment disc 20 is rotatably mounted on the mounting plate 10 by inserting the first rotating shaft 21 into the shaft hole 11. The first rotating shaft 21 has a second rotating shaft 22 eccentrically mounted on it. The second rotating shaft 22 has an adjustment wheel 23 mounted on it. By eccentrically mounting the second rotating shaft 22, rotating the adjustment disc 20 will cause the first rotating shaft 21 to rotate, thereby changing the position of the second rotating shaft 22 and thus changing the position of the adjustment wheel 23, thereby adjusting the tension of the connecting piece and solving the problem of low adjustment efficiency.

[0028] The distance between the axes of the first rotating shaft 21 and the second rotating shaft 22 is 30-100 mm, preferably 50 mm.

[0029] The adjusting disc 20 is also provided with a first mounting hole 24, which is located on the edge of the end face of the adjusting disc 20. A rod can be inserted into the first mounting hole 24, and force can be applied to the rod to make the adjusting disc 20 rotate around the first rotating shaft 21, thereby changing the position of the second rotating shaft 22, and thus changing the position of the adjusting wheel 23. This is convenient and labor-saving, and makes it easy to adjust the adjusting disc 20.

[0030] It should be understood that the first mounting hole 24 can also be located on the periphery of the adjusting plate 20.

[0031] The adjusting plate 20 is provided with an arc-shaped through hole 25 penetrating the adjusting plate 20. The virtual center of the arc of the arc-shaped through hole 25 coincides with the center of the first rotating shaft 21. The mounting plate 10 is provided with a second mounting hole 12 corresponding to the arc-shaped through hole 25. During assembly, the adjusting plate 20 is screwed onto the mounting plate 10 through the arc-shaped through hole 25 and screwed into the second mounting hole 12 by screws or bolts. By setting the arc-shaped through hole 25, when adjusting the tension of the connecting parts, the bolt passing through the arc-shaped through hole 25 can be moved along the arc-shaped through hole 25 by rotating the adjusting plate 20, so as to achieve stable adjustment.

[0032] It also includes a drive motor 30, which is equipped with a drive mounting bracket 31. The drive motor 30 is mounted on the mounting plate 10 via the drive mounting bracket 31. The drive mounting bracket 31 has a protective cylinder 32, which has a clearance groove 321. The output end of the drive motor 30 drives and connects to the adjusting wheel 23 through the clearance groove 321 via a connector. It also includes a driven wheel 13. The adjusting wheel 23 is a double wheel, which includes a first adjusting wheel 231 and a second adjusting wheel 232. The drive motor 30 drives and connects to the first adjusting wheel 231 via a connector, and the driven wheel 13 drives and connects to the second adjusting wheel 232 via a connector. By setting the protective cylinder 32, the output end of the drive motor 30 can be protected to avoid impact damage to the output end of the drive motor 30, thereby reducing production costs.

[0033] The protective cylinder 32 extends radially outward at both ends to form a first mounting portion 33 and a second mounting portion 34, respectively. The drive motor 30 is mounted on the first mounting portion 33, and the second mounting portion 34 is mounted on the mounting plate 10. The second mounting portion 34 is provided with a plurality of third mounting holes 341, and the mounting plate 10 is provided with a plurality of fourth mounting holes 14 corresponding to the third mounting holes 341. The drive mounting bracket 31 is mounted on the mounting plate 10 by screws or bolts passing through the third mounting holes 341 and screwing into the fourth mounting holes 14. The third mounting holes 341 are racetrack-shaped holes. By cooperating with the third mounting holes 341 and the fourth mounting holes 14, the position of the drive motor 30 can be adjusted to improve applicability.

[0034] In this utility model, the output end of the drive motor 30 is provided with a drive wheel, and the drive motor 30 is wound around the drive wheel and the first adjusting wheel 231 through a connecting member, thereby driving the first adjusting wheel 231.

[0035] The method of using this utility model is as follows: When tension of the connector is required, the adjusting disc 20 can be rotated directly or an external rod can be inserted into the first mounting hole 24 to rotate the adjusting disc 20. The rotation of the adjusting disc 20 causes the position of the adjusting wheel 23 to change, thereby adjusting the tension of the connector.

[0036] This invention rotatably mounts the adjusting disc 20 on the mounting plate 10 and eccentrically mounts the rotating shaft on the adjusting disc 20. By rotating the adjusting disc 20, the position of the second rotating shaft 22 can be changed, thereby changing the position of the adjusting wheel 23, thus achieving the adjustment of the tension of the connecting parts and improving work efficiency.

[0037] 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.
