Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a tensioning device for a belt conveyor. Background Technology

[0002] EVA is a material copolymerized from ethylene and vinyl acetate, and its market demand continues to rise, especially in the footwear industry where it is widely used. In the production of EVA footwear materials, a mixing device is typically used to blend at least two foaming materials.

[0003] To ensure continuous material conveying and improve feeding accuracy, the applicant filed a material metering discharge structure application on June 11, 2024 (application number CN202421305628.8). This material metering discharge structure uses a conveyor belt to transport materials, ensuring continuous conveying. However, the conveyor belt in this structure cannot be tensioned during use. In view of the aforementioned problems, the inventors of this case conducted in-depth research on this issue, resulting in this application. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a tensioning device for a belt conveyor, which can realize the tension adjustment of the conveyor belt of the belt conveyor.

[0005] This utility model is implemented as follows: a tensioning device for a belt conveyor, comprising a belt seat, a driving pulley rotatably disposed at one end of the belt seat, a driven pulley rotatably disposed at the other end of the belt seat, a fixed pusher and a movable pusher;

[0006] The belt seat includes a first part and a second part, with the first part and the second part movably joined together at opposite ends. A fixed pusher is located inside the first part and near the end of the second part. An insertion hole is formed on the side wall of the second part near the end of the first part, and the movable pusher is inserted into the insertion hole. A first inclined surface is formed on the side of the fixed pusher facing the movable pusher, and a second inclined surface is formed on the side of the movable pusher facing the fixed pusher, which contacts the first inclined surface. The distance between the driving pulley and the driven pulley can be adjusted by pushing and pulling the movable pusher.

[0007] Furthermore, both the first and second parts are hollow structures.

[0008] Furthermore, the upper and lower surfaces of the second part are each formed with a first sliding limiting groove at the end near the first part, and the upper and lower surfaces of the first part are each formed with a first sliding limiting piece at the end near the second part. The first sliding limiting piece and the first sliding limiting groove are slidably spliced ​​together.

[0009] Furthermore, a second sliding limiting groove is formed on the front and rear surfaces of the second part at the end near the first part, and a second sliding limiting piece is formed on the front and rear surfaces of the first part at the end near the second part. The second sliding limiting piece and the second sliding limiting groove are slidably spliced ​​together.

[0010] Furthermore, at least one first locking hole is provided on the second sliding limit piece, and the fixed pusher is locked to the second sliding limit piece.

[0011] Furthermore, the push-pull end of the movable pusher is provided with a connecting part, and a through hole is provided through the connecting part. The side wall of the second part is provided with a second locking hole at the position corresponding to the through hole. The connecting part is locked to the side wall of the second part through a locking member.

[0012] Furthermore, the fixed pusher has a right-angled trapezoidal structure.

[0013] Furthermore, the movable pusher has a right-angled triangular structure.

[0014] By adopting the technical solution of this utility model, at least the following beneficial effects are achieved: The design allows the first and second parts to be movably joined at their opposite ends. A fixed pusher is provided inside the first part near the end of the second part. An insertion hole is opened on the side wall of the second part near the end of the first part. Simultaneously, inclined surfaces are formed on the opposite sides of the fixed and movable pushers to facilitate mutual contact and engagement. This allows for adjustment of the distance between the driving and driven pulleys by pushing and pulling the movable pusher after it is inserted into the insertion hole, thus effectively adjusting the tension of the conveyor belt fitted between the driving and driven pulleys. Furthermore, by controlling the machining precision of the first and second parts, the parallelism of the two shafts of the driving and driven pulleys can be achieved. This minimizes the impact of parallelism during assembly without requiring special adjustments, ensuring smooth operation of the conveyor belt. Attached Figure Description

[0029] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] It should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing these embodiments and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0031] Please see Figures 1 to 6As shown in the preferred embodiment of the tensioning device for a belt conveyor of the present invention, the tensioning device includes a belt seat 1, a driving pulley 2 rotatably disposed at one end of the belt seat 1, a driven pulley 3 rotatably disposed at the other end of the belt seat 1, a fixed pusher 4, and a movable pusher 5.

[0032] The mounting bracket 1 includes a first part 11 and a second part 12. The first part 11 and the second part 12 are movably joined together at opposite ends, allowing movement between them. A fixed pusher 4 is located inside the first part 11 and near the end of the second part 12. An insertion hole 121 is formed on the side wall of the second part 12 near the end of the first part 11. A movable pusher 5 is inserted into the insertion hole 121, allowing it to be pushed inward or pulled outward during use. The fixed pusher 4 has a first inclined surface 41 on the side facing the movable pusher 5, and the movable pusher 5 has a second inclined surface 51 on the side facing the fixed pusher 4 that contacts the first inclined surface 41. Figure 3 and Figure 6 As shown, the distance between the driving pulley 2 and the driven pulley 3 can be adjusted by pushing and pulling the movable pusher 5, thereby enabling the tension adjustment of the conveyor belt 6 sleeved between the driving pulley 2 and the driven pulley 3.

[0033] This utility model is designed so that the first part 11 and the second part 12 are movably spliced ​​together at their opposite ends. A fixed pusher 4 is provided inside the first part 11 near the end of the second part 12. An insertion hole 121 is opened on the side wall of the second part 12 near the end of the first part 11. At the same time, inclined surfaces that contact and cooperate with each other are formed on the opposite side of the fixed pusher 4 and the movable pusher 5. In actual use, when the movable pusher 5 is inserted into the insertion hole 121, the distance between the driving pulley 2 and the driven pulley 3 can be adjusted by pushing and pulling the movable pusher 5. This can effectively adjust the tension of the conveyor belt 6 sleeved between the driving pulley 2 and the driven pulley 3.

[0034] In a preferred embodiment of this utility model, both the first split 11 and the second split 12 are hollow structures, which not only facilitates the installation of the fixed pusher 4 and the movable pusher 5 in the first split 11 and the second split 12, but also reduces the weight of the entire seat 1.

[0035] In the preferred embodiment of this utility model, please refer to the following: Figure 4 and Figure 5As shown, the upper and lower surfaces of the second split 12 are each formed with a first sliding limiting groove 122 at the end near the first split 11, and the upper and lower surfaces of the first split 11 are each formed with a first sliding limiting piece 111 at the end near the second split 12. The first sliding limiting piece 111 and the first sliding limiting groove 122 are slidably spliced ​​together.

[0036] Furthermore, the front and rear surfaces of the second segment 12 each have a second sliding limiting groove 123 formed at the end near the first segment 11, and the front and rear surfaces of the first segment 11 each have a second sliding limiting piece 112 formed at the end near the second segment 12. The second sliding limiting piece 112 is slidably connected to the second sliding limiting groove 123. In specific implementation of this utility model, because the tension adjustment range of the conveyor belt 6 is relatively small, the specific lengths of the first sliding limiting groove 122, the second sliding limiting groove 123, the first sliding limiting piece 111, and the second sliding limiting piece 112 can all be designed according to actual needs. It is only necessary to ensure that the first sliding limiting piece 111 does not completely detach from the first sliding limiting groove 122 during the entire tension adjustment process, and similarly, the second sliding limiting piece 112 does not completely detach from the second sliding limiting groove 123. Meanwhile, in the specific implementation of this utility model, it is only necessary to fix the second part 12 in the required position, so that the first part 11 can be driven to slide relative to the second part 12 by pushing and pulling the movable pusher 5, thereby realizing the tension adjustment function.

[0037] This invention designs the second split body 12 to have a first sliding limiting groove 122 formed on its upper and lower surfaces, and a second sliding limiting groove 123 formed on its front and rear surfaces. Simultaneously, the first split body 11 has a first sliding limiting piece 111 formed on its upper and lower surfaces, and a second sliding limiting piece 112 formed on its front and rear surfaces. This design allows the first split body 11 to be limited in position during use by the cooperation of the first sliding limiting groove 122, the second sliding limiting groove 123, the first sliding limiting piece 111, and the second sliding limiting piece 112, ensuring smooth sliding adjustment of the first split body 11.

[0038] Meanwhile, in specific implementation, the parallelism of the two shafts of the driving pulley 2 and the driven pulley 3 can be achieved by adjusting the machining precision requirements of the first part 11 and the second part 12. This allows the influence of parallelism to be minimized without special adjustments during the assembly process, thereby ensuring the smooth operation of the conveyor belt 6.

[0039] In a preferred embodiment of the present invention, at least one first locking hole 1121 is provided on the second sliding limit piece 112. For example, two first locking holes 1121 can be provided on the second sliding limit piece 112. The fixed pusher 4 is locked and connected to the second sliding limit piece 112. Specifically, screws or bolts can be used to lock and fix the fixed pusher 4 to the second sliding limit piece 112 together.

[0040] In a preferred embodiment of this invention, the push-pull end of the movable pusher 5 is provided with a connecting part 52, and a through hole 521 is provided through the connecting part 52. A second locking hole 124 is provided on the side wall of the second split 12 at the position corresponding to the through hole 521. The connecting part 52 is locked to the side wall of the second split 12 via a locking member (not shown), which can specifically be a bolt. This invention, by using a locking member to lock the connecting part 52 to the side wall of the second split 12, can prevent the movable pusher 5 from loosening or falling off during use. The movable pusher 5 can also be adjusted by rotating the bolt.

[0041] In a preferred embodiment of this utility model, the fixed pusher 4 has a right-angled trapezoidal structure to ensure the overall strength of the fixed pusher 4.

[0042] In a preferred embodiment of this utility model, the movable pusher 5 has a right-angled triangular structure to ensure the overall strength of the movable pusher 5.

[0043] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
