[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 quantitative discharge structure application on June 11, 2024 (application number CN202421305628.8). This structure uses a conveyor belt to transport materials, ensuring continuous conveying. However, after actual use, the applicant discovered the following defects: the conveyor belt tension cannot be adjusted during use, and the conveyor belt is prone to deviation, resulting in poor stability. Materials can easily get stuck in the conveyor belt from both sides, compromising feeding accuracy. In view of the above problems, the inventors of this case conducted in-depth research, leading to this application. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a belt conveyor device that solves the problems of existing technology, such as the inability to adjust the tension of the conveyor belt during use, the easy occurrence of belt deviation, poor stability, and the easy for materials to get stuck in the conveyor belt from both sides, which makes it impossible to guarantee the accuracy of material supply.

[0005] This utility model is implemented as follows: A belt conveyor device includes 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 conveyor belt sleeved between the driving belt and the driven belt, a drive mechanism for driving the driving pulley to rotate, and a tension adjustment mechanism. The belt seat includes a first part and a second part, the second part is fixedly disposed, and one end of the first part and the second part are movably spliced ​​together. The tension adjustment mechanism is disposed between the first part and the second part, and the distance between the driving pulley and the driven pulley is adjusted by driving the first part to move through the tension adjustment mechanism.

[0006] Furthermore, it also includes an upper cover that covers the conveyor belt, the bottom sides of which are in contact with or adjacent to the upper surface of the conveyor belt, and the top of the upper cover has a feeding opening.

[0007] Furthermore, both the driving pulley and the driven pulley gradually decrease in size from the middle position to both ends along the axial direction, and the two ends and the middle position of the driving pulley and the driven pulley are aligned with each other.

[0008] Furthermore, the tension adjustment mechanism includes a fixed pusher and a movable pusher. The fixed pusher is located inside the first part and near the end of the second part. The side wall of the second part has an insertion hole at the end near the first part, and the movable pusher is inserted into the insertion hole. The fixed pusher has a first inclined surface on the side facing the movable pusher, and the movable pusher has a second inclined surface on the side facing the fixed pusher that contacts the first inclined surface.

[0009] 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.

[0010] The front and rear surfaces of the second part each have a second sliding limiting groove formed at the end near the first part, and the front and rear surfaces of the first part each have a second sliding limiting piece formed at the end near the second part. The second sliding limiting piece and the second sliding limiting groove are slidably spliced ​​together.

[0011] Furthermore, the outer surface of the drive pulley is provided with several anti-slip protrusions in a circumferential direction from one end to the other.

[0012] Furthermore, the two sides of one end of the belt seat extend outward to form a first extension piece, and a bearing seat clamping groove is formed on the first extension piece. The bearing seat is clamped in the bearing seat clamping groove, and the drive pulley is rotatably connected to the bearing seat through a first shaft.

[0013] The other end of the belt seat has two sides extending outward to form a second extension piece, and a shaft clamping groove is formed on the second extension piece. The driven pulley is rotatably connected to the shaft clamping groove through a second shaft.

[0014] Furthermore, the drive mechanism includes a drive motor, a first drive wheel, a second drive wheel, and a drive belt. The first drive wheel is connected to the output end of the drive motor, the second drive wheel is connected to one end of the first shaft, and the drive belt is sleeved between the first drive wheel and the second drive wheel.

[0015] Furthermore, support plates are provided on both sides of the first and second parts, and adjustment slots are opened on the upper part of the support plates along the horizontal direction. The support plates and the upper cover are locked together by locking bolts passing through the adjustment slots.

[0016] Furthermore, it also includes a weighing device, which is located below the belt seat and connected to the belt seat.

[0017] By adopting the technical solution of this utility model, at least the following beneficial effects are achieved: The tension adjustment mechanism is used to adjust the tension of the conveyor belt. Both the driving and driven pulleys are designed to gradually shrink from the middle to both ends along the axial direction, i.e., both the driving and driven pulleys have a conical structure with a raised center. This effectively reduces the parallelism requirements of the two shafts of the driving and driven pulleys during operation. The driving and driven pulleys are also used to automatically correct the conveyor belt, ensuring it remains centered during operation and allowing for outward extension. Simultaneously, an upper cover is provided above the conveyor belt, with its bottom sides contacting or adjacent to the upper surface of the conveyor belt. This reduces the size of the guide trough formed above the conveyor belt, ensuring that materials fed from the top of the upper cover are positioned in the middle of the conveyor belt. Therefore, by adopting the above-mentioned technical solution of this utility model, the stability of the conveyor belt can be reliably improved, and the material conveyed by the conveyor belt can be prevented from falling from both sides and getting stuck in the conveyor belt, thereby ensuring the accuracy of the conveyor belt during material feeding.

[0039] 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.

[0040] 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.

[0041] Please see Figures 1 to 9 As shown in the preferred embodiment of the belt conveyor device 100 of this utility model, the belt conveyor device 100 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 conveyor belt 4 sleeved between the driving belt 2 and the driven belt 3, a drive mechanism 5 for driving the driving pulley 2 to rotate, and a tension adjustment mechanism 6. During operation, the drive mechanism 5 drives the driving pulley 2 to rotate, and the driving pulley 2 will drive the conveyor belt 4 to transmit power and the driven belt 3 to rotate during the rotation process.

[0042] The belt seat 1 includes a first part 11 and a second part 12. The second part 12 is fixedly installed, and one end of the first part 11 and the second part 12 are movably spliced ​​together. The tension adjustment mechanism 6 is located between the first part 11 and the second part 12. The tension adjustment mechanism 6 drives the first part 11 to move to adjust the distance between the driving pulley 2 and the driven pulley 3, thereby adjusting the tension of the conveyor belt 4.

[0043] This utility model designs the belt support 1 to include a first part 11 and a second part 12, and movably splices one end of the first part 11 and the second part 12 together. A tension adjustment mechanism 6 is provided between the first part 11 and the second part 12, so that in the actual use, the tension adjustment mechanism 6 can be used to drive the first part 11 to move and adjust the distance between the driving pulley 2 and the driven pulley 3, thereby enabling the tension adjustment of the conveyor belt 4.

[0044] In the preferred embodiment of this utility model, please refer to the following: Figure 1 and Figure 2 As shown, the belt conveyor device 100 also includes an upper cover 7 covering the conveyor belt 4. The bottom sides of the upper cover 7 are in contact with or adjacent to the upper surface of the conveyor belt 4, so as to limit the two sides of the conveyor belt 4 by the upper cover 7, thereby improving the stability of the conveyor belt 4 during the transmission process, so that the conveyed material will not fall from the sides and get stuck in the conveyor belt 4. The top of the upper cover 7 is provided with a feeding opening 71 to facilitate the feeding of material to the conveyor belt 4.

[0045] In a preferred embodiment of the present invention, both the driving pulley 2 and the driven pulley 3 gradually decrease in size from the middle position to both ends along the axial direction, that is, both the driving pulley 2 and the driven pulley 3 have a conical structure with a convex center, and the two ends and the middle position of the driving pulley 2 and the driven pulley 3 are aligned with each other.

[0046] Because conventional cylindrical drive and driven pulleys require a high degree of parallelism between the two shafts, otherwise the conveyor belt can easily deviate during long-term operation. In actual use, it is often necessary to make two shoulders on both sides of the pulley to limit the deviation of the conveyor belt. This invention utilizes a tension adjustment mechanism 6 to adjust the tension of the conveyor belt 4. Both the driving pulley 2 and the driven pulley 3 are designed to gradually taper from the center outwards along the axial direction, forming a conical structure with a central convex shape. This effectively reduces the parallelism requirements of the two axes of the driving pulley 2 and driven pulley 3 during operation. The driving pulley 2 and driven pulley 3 also enable automatic correction of the conveyor belt 4, ensuring it remains centered during operation and allowing for outward extension. Furthermore, an upper cover 7 is positioned above the conveyor belt 4, with its bottom sides contacting or adjacent to the upper surface of the conveyor belt 4. This reduces the size of the guide trough formed above the conveyor belt 4, ensuring that materials fed from the top of the upper cover 7 are positioned in the center of the conveyor belt 4. Therefore, by adopting the above-mentioned technical solution of this utility model, the stability of the conveyor belt 4 can be reliably improved, and the material conveyed by the conveyor belt 4 can be prevented from falling from both sides and getting stuck in the conveyor belt 4, thereby ensuring the accuracy of the conveyor belt 4 when feeding materials.

[0047] In the preferred embodiment of this utility model, please refer to the following: Figure 4 As shown, the tension adjustment mechanism 6 includes a fixed pusher 61 and a movable pusher 62. The fixed pusher 61 is located inside the first segment 11 and near the end of the second segment 12. An insertion hole 121 is formed on the side wall of the second segment 12 near the end of the first segment 11, and the movable pusher 62 is inserted into the insertion hole 121. The fixed pusher 61 has a first inclined surface 611 on the side facing the movable pusher 62, and the movable pusher 62 has a second inclined surface 621 on the side facing the fixed pusher 61 that contacts the first inclined surface 611. In practical use, when the movable pusher 62 is pushed into the insertion hole 121, the first segment 11 can move away from the second segment 12 under the combined action of the first inclined surface 611 and the second inclined surface 621, thereby achieving tension adjustment of the conveyor belt 4.

[0048] In a specific implementation of this utility model, both the first split 11 and the second split 12 are hollow structures. This not only facilitates the installation of the fixed pusher 61 and the movable pusher 62 within the first split 11 and the second split 12, but also reduces the weight of the entire seat 1.

[0049] In the preferred embodiment of this utility model, please refer to the following: Figure 5 and Figure 6As 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.

[0050] 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. 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 spliced ​​together with the second sliding limiting groove 123, and the fixing pusher 61 is specifically locked and fixed together with the second sliding limiting piece 112. In the specific implementation of this utility model, since the tension adjustment range of the conveyor belt 4 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.

[0051] 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.

[0052] 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 impact of parallelism to be minimized without special adjustments during the assembly process, thereby ensuring the smooth operation of the conveyor belt 4.

[0053] In a specific implementation of this invention, the push-pull end of the movable pusher 62 is provided with a connecting part 622, and the connecting part 622 is locked to the side wall of the second part 12 via a locking member (not shown), wherein the locking member can specifically be a bolt. By using a locking member to lock the connecting part 622 to the side wall of the second part 12, this invention prevents the movable pusher 62 from loosening or falling off during use, and also allows for adjustment of the movable pusher 62 by rotating the bolt.

[0054] In one specific embodiment of this utility model, in order to ensure the overall strength of the fixed pusher 61 and the movable pusher 62, the fixed pusher 61 is a right trapezoidal structure and the movable pusher 62 is a right triangle structure.

[0055] In a preferred embodiment of this utility model, the outer surface of the drive pulley 2 is provided with several anti-slip protrusions 21 around the circumference from one end to the other to increase the friction between the drive pulley 2 and the conveyor belt 4, ensuring that the conveyor belt 4 will not slip during operation.

[0056] In a preferred embodiment of this utility model, the two sides of one end of the belt seat 1 extend outward to form a first extension piece 13, and a shaft seat clamping groove 14 is formed on the first extension piece 13. The shaft seat 8 is clamped in the shaft seat clamping groove 14, and the drive pulley 2 is rotatably connected to the shaft seat 8 through a first shaft body 22. This utility model adopts the method of rotatably connecting the drive pulley 2 to the shaft seat 8 through the first shaft body 22 and clamping the shaft seat 8 in the shaft seat clamping groove 14 of the first extension piece 13, so that in the actual use, the shaft seat 8, the first shaft body 22 and the drive pulley 2 can be disassembled, thereby facilitating actual replacement, maintenance and other operations. In a specific implementation of this utility model, the bearing seat 8 has an annular structure, and the outer wall of the bearing seat 8 has an annular groove 81 that mates with the bearing seat clamping groove 14 around the circumference. During use, the annular groove 81 can be used to achieve axial limiting function. The bearing seat clamping groove 14 has a first assembly slot 141, and the size of the first assembly slot 141 is smaller than the outer diameter of the bearing seat 8 at the position corresponding to the annular groove 81, so as to ensure that after the bearing seat 8 is assembled into the bearing seat clamping groove 141, the bearing seat 8 will not detach from the bearing seat clamping groove 141 without human intervention.

[0057] The other end of the belt seat 1 has two outwardly extending sides forming second extension plates 15. A shaft clamping groove 16 is formed on the second extension plate 15. The driven pulley 3 is rotatably connected to the shaft clamping groove 16 via a second shaft 31. In a specific implementation of this invention, the shaft clamping groove 16 forms a second mounting slot 161, and the size of the second mounting slot 161 is smaller than the outer diameter of the second shaft 31. This ensures that after the second shaft 31 is assembled into the shaft clamping groove 16, it will not detach from the shaft clamping groove 16 without human intervention. This invention uses a rotatable connection between the driven pulley 3 and the shaft clamping groove 16 of the second extension plate 15 via the second shaft 31, allowing for disassembly and separation of the driven pulley 3 and the second shaft 31 during use, thus facilitating operations such as replacing the driven pulley 3.

[0058] In the preferred embodiment of this utility model, please refer to the following: Figure 1 As shown, the drive mechanism 5 includes a drive motor 51, a first drive wheel 52, a second drive wheel 53, and a drive belt 54. The first drive wheel 52 is connected to the output end of the drive motor 51, and the second drive wheel 53 is connected to one end of the first shaft 22. The drive belt 54 is sleeved between the first drive wheel 52 and the second drive wheel 53. When the drive mechanism 5 is working, the drive motor 51 drives the first drive wheel 52 to rotate. When the first drive wheel 52 rotates, it drives the second drive wheel 53 to rotate via the drive belt 54. When the second drive wheel 53 rotates, it drives the first shaft 22 and the drive pulley 2 to rotate. When the drive pulley 2 rotates, it drives the conveyor belt 4 to transmit power.

[0059] In a preferred embodiment of this utility model, support plates 17 are provided on both sides of the first split body 11 and the second split body 12. The upper part of the support plate 17 is provided with an adjustment slot 171 along the horizontal direction. The support plate 17 and the upper cover body 7 are locked together by a locking bolt (not shown) passing through the adjustment slot 171, so that the first split body 11 and the second split body 12 can support the upper cover body 7. At the same time, when the tension adjustment mechanism 6 drives the second split body 12 to move, the locking bolt on the support plate 17 corresponding to the second split body 12 needs to be loosened to ensure that the second split body 12 can move normally.

[0060] In a preferred embodiment of this utility model, the belt conveyor 100 further includes a weighing device 9, which is located below the belt seat 1 and connected to the belt seat 1. In actual operation, the belt conveyor 100 of this utility model can both support the entire belt conveyor 100 using the weighing device 9 and perform a weighing function using the weighing device 9.
