Description

Technical Field

[0001] This utility model belongs to the technical field of belt conveyors, specifically, it relates to an adjustable pressure belt pulley for belt conveyors. Background Technology

[0002] Belt conveyors, also known as rubber belt conveyors, are widely used in various industries such as home appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, and food for the assembly, testing, debugging, packaging, and transportation of objects. As is well known, belt conveyors with concave arc sections generally produce belt slippage during operation. Therefore, 1-3 sets of pressure rollers are arranged in the concave arc section to avoid personal injury accidents caused by belt slippage and to reduce the service life of the idler rollers.

[0003] A search revealed that CN216271408U discloses an adjustable pressure roller. Through the cooperation of a fixed bracket, a movable bracket mechanism, a pressure roller assembly mechanism, a clamping edge, and an L-shaped clamping plate, two mounting seats can be fixed on two mounting plates. The movable plate is then connected to the fixed bracket via bolts on a positioning block, facilitating the adjustment of the movable plate's position.

[0004] However, the pressure roller cannot be adjusted laterally, which means that the distance between the two pressure rollers is fixed. Therefore, it can only be used to correct the belt width of a single conveyor belt, which reduces the applicability of the pressure roller and makes it inconvenient to use.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the aforementioned technical problem of fixing two mounting seats to two mounting plates and connecting the movable plate to the fixed bracket via bolts on the positioning block, using a combination of a fixed bracket, a movable bracket mechanism, a pressure roller assembly mechanism, a clamping edge, and an L-shaped clamping plate, thereby facilitating the adjustment of the movable plate's position, the basic concept of this utility model is as follows:

[0007] An adjustable belt pulley for a belt conveyor, including a support frame;

[0008] A connecting frame is fixedly connected to the outer wall of the top of the bracket. The bracket is provided with a horizontal adjustment mechanism, and vertical adjustment mechanisms are provided on both sides of the horizontal adjustment mechanism. The horizontal adjustment mechanism includes a rotating column. A sliding groove is formed on the outer wall of the rotating column. A limiting sliding groove is formed on the inner wall of the sliding groove. A positioning hole is formed on the inner wall of the limiting sliding groove. A connecting slider is slidably arranged on the inner wall of the limiting sliding groove. A sliding hole is formed on the outer wall of the connecting slider. A spring is fixedly connected to the inner wall of the sliding hole. A positioning rod is fixedly connected to the end of the spring away from the inner wall of the sliding hole. A connecting rod is fixedly connected to the outer wall of the positioning rod. A lever is fixedly connected to the end of the connecting rod away from the positioning rod. A pressure roller is fixedly connected to the outer wall of the top of the connecting slider. A rubber ring is fixedly connected to the outer wall of the pressure roller.

[0009] In a preferred embodiment of this utility model, the vertical adjustment mechanism includes a motor. The outer wall of the bracket has a groove, and the bottom of the inner wall of the groove has a mounting groove. The outer wall of the motor is mounted on the inner wall of the mounting groove. A lead screw is fixedly connected to the output end of the motor. A threaded block is threadedly connected to the outer wall of the lead screw. The outer wall of the threaded block is rotatably connected to a rotating column through a bearing. A support slider is rotatably connected to the end of the rotating column away from the threaded block through a bearing. A support groove is provided on the other outer wall of the bracket. A sliding rod is fixedly connected to the inner wall of the support groove. The outer wall of the support slider is slidably mounted on the outer wall of the sliding rod.

[0010] In a preferred embodiment of this utility model, the number of positioning holes is several, and the positioning holes are evenly and equidistantly distributed on the inner wall of the limiting slide groove.

[0011] In a preferred embodiment of this utility model, the outer wall of the positioning rod is fitted to the inner wall of the positioning hole, and there are four positioning rods, which are distributed symmetrically on the connecting slider in pairs.

[0012] In a preferred embodiment of this utility model, the limiting groove is disposed at the upper and lower ends of the inner wall of the groove, and the inner wall of the limiting groove is fitted to the outer wall of the connecting slider.

[0013] In a preferred embodiment of this utility model, the outer wall of the threaded block is fitted to the inner wall of the groove opened on the outer wall of the bracket, and the support slider is fitted to the inner wall of the support groove opened on the outer wall of another bracket.

[0014] In a preferred embodiment of this utility model, the outer wall of the connecting slider is provided with a connecting groove, and the outer wall of the connecting rod is movably disposed on the inner wall of the connecting groove.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] In this invention, the levers on both sides of the connecting slider are first pinched inward. This causes the levers to move the connecting rod, which in turn moves the positioning rod inward into the connecting slider. During this movement, the spring exerts a squeezing action, causing the positioning rod to disengage from the locking limit between itself and the inner wall of the positioning hole. The connecting slider is then released from its limit and can be moved left and right, causing the outer walls of the upper and lower ends of the connecting slider to move within the inner wall of the limiting groove. This movement of the connecting slider then moves the pressure rollers, allowing adjustment of the lateral distance between the two pressure rollers to accommodate conveyors of different widths.

[0017] In this invention, when vertical adjustment of the pressure roller is required, the motor can be started, and its output end will drive the lead screw to rotate. The rotation of the lead screw will drive the threaded block connected to its outer wall to move up and down. The movement of the threaded block will drive the rotating column and the pressure roller to move up and down. At the same time, the other end of the rotating column will drive the support slider to move up and down on the inner wall of the slide bar, thereby supporting the other end of the rotating column and improving the stability of the rotating column during the up and down adjustment process. In this way, the height of the pressure roller can be adjusted according to the height of the conveyor, thereby further improving the applicability of the pressure roller and making it easier to use.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 5 As shown, a belt conveyor with adjustable belt guide roller includes a support 1 fixedly connected to a connecting frame 2 on the outer wall of the top of the support 1. A lateral adjustment mechanism 31 is provided on the support 1, and vertical adjustment mechanisms 32 are provided on both sides of the lateral adjustment mechanism 31. The lateral adjustment mechanism 31 includes a rotating column 311, a groove 312 formed on the outer wall of the rotating column 311, a limiting groove 313 formed on the inner wall of the groove 312, and a positioning hole 314 formed on the inner wall of the limiting groove 313. A connecting slider 315 is provided on the wall. A sliding hole is opened on the outer wall of the connecting slider 315. A spring 316 is fixedly connected to the inner wall of the sliding hole. A positioning rod 317 is fixedly connected to the end of the spring 316 away from the inner wall of the sliding hole. A connecting rod 318 is fixedly connected to the outer wall of the positioning rod 317. A lever 319 is fixedly connected to the end of the connecting rod 318 away from the positioning rod 317. A pressure roller 3110 is fixedly connected to the outer wall of the top of the connecting slider 315. A rubber ring 3111 is fixedly connected to the outer wall of the pressure roller 3110.

[0028] Furthermore, there are several positioning holes 314, which are evenly and equidistantly distributed on the inner wall of the limiting slide groove 313, so that multiple adjustment levels can be made to accommodate more specifications of conveyors.

[0029] Furthermore, the outer wall of the positioning rod 317 fits snugly against the inner wall of the positioning hole 314. There are four positioning rods 317, which are symmetrically distributed in pairs on the connecting slider 315, thus ensuring the stability of the connecting slider 315 during the positioning process.

[0030] Furthermore, the limiting groove 313 is set at the upper and lower ends of the inner wall of the groove 312. The inner wall of the limiting groove 313 fits snugly against the outer wall of the connecting slider 315, thereby improving the stability of the moving support of the connecting slider 315.

[0031] The vertical adjustment mechanism 32 includes a motor 321. The outer wall of the bracket 1 has a groove, and the bottom of the inner wall of the groove has a mounting groove. The outer wall of the motor 321 is mounted on the inner wall of the mounting groove. The output end of the motor 321 is fixedly connected to a lead screw 322. The outer wall of the lead screw 322 is threadedly connected to a threaded block 323. The outer wall of the threaded block 323 is rotatably connected to a rotating column 311 through a bearing. The end of the rotating column 311 away from the threaded block 323 is rotatably connected to a support slider 325 through a bearing. The other outer wall of the bracket 1 has a support groove. The inner wall of the support groove is fixedly connected to a slide rod 324. The outer wall of the support slider 325 is slidably mounted on the outer wall of the slide rod 324.

[0032] Furthermore, the outer wall of the threaded block 323 fits into the inner wall of the groove on the outer wall of the bracket 1, and the support slider 325 fits into the inner wall of the support groove on the outer wall of another bracket 1, thereby ensuring stability during bidirectional adjustment.

[0033] Furthermore, the outer wall of the connecting slider 315 is provided with a connecting groove, and the outer wall of the connecting rod 318 is movably disposed on the inner wall of the connecting groove, thereby providing the connecting rod 318 with room for movement, which can drive the positioning rod 317 to move.

[0034] The implementation principle of the adjustable belt pulley for a belt conveyor in this embodiment is as follows: When the rubber ring 3111 needs to be adjusted laterally, firstly, the levers 319 on both sides of the connecting slider 315 are pinched inward. At this time, the levers 319 will drive the connecting rod 318 to move. The movement of the connecting rod 318 will drive the positioning rod 317 to move inward into the connecting slider 315. At the same time, during the movement, the spring 316 will be squeezed. At this time, the positioning rod 317 will disengage from the locking limit between itself and the inner wall of the positioning hole 314 by moving inward. At this time, the connecting slider 315 will be released from the limit. After the limit is released, the connecting slider 315 can be moved left and right, so that... The upper and lower outer walls of the connecting slider 315 move within the limiting groove 313. This movement of the connecting slider 315 drives the pressure roller 3110 to move, thus adjusting the lateral distance between the two pressure rollers 3110 to accommodate conveyors of different widths. After the two pressure rollers 3110 are moved to the appropriate position, the lever 319 can be released. The spring 316 then rebounds, causing the positioning rod 317 to reset. The outer wall of the positioning rod 317 then engages with the inner wall of the positioning hole 314, thus completing the limiting again. This improves the applicability of the pressure roller and makes it easier for workers to use.

[0035] When vertical adjustment of the pressure roller 3110 is required, the motor 321 can be started. Its output end will drive the lead screw 322 to rotate. The rotation of the lead screw 322 will drive the threaded block 323, which is threaded to its outer wall, to move up and down. The movement of the threaded block 323 will drive the rotating column 311 and the pressure roller 3110 to move up and down. At the same time, the other end of the rotating column 311 will drive the support slider 325 to move up and down on the inner wall of the slide rod 324, thereby supporting the other end of the rotating column 311 and improving the stability of the rotating column 311 during the up and down adjustment process. In this way, the height of the pressure roller 3110 can be adjusted according to the height of the conveyor, thereby further improving the applicability of the pressure roller 3110 and making it easier to use.
