[0007] As a preferred technical scheme of the application, the tensioning wheel abuts against the surface of the conveying belt, the extrusion mechanism is in the shape of U, a connecting rod III penetrates through the sliding groove II, one end of the connecting rod III close to the sliding block is fixedly connected with the sliding rod, and the surface of the connecting rod III is sleeved with a slidingly connected tooth rod.

[0008] As a preferred technical scheme of the application, one end of the tooth rod is engaged with a gear II, the bottom of the gear II is rotatably connected with the base, the top of the gear II is fixedly connected with a gear I, and the gear I is located on the top of the base through a penetrating groove.

[0009] As a preferred technical scheme of the application, the surface of the gear I is engaged with a moving rod, the bottom of the moving rod is fixedly connected with the top of the sliding block through a connecting block, the top of the back surface of the base is provided with a sliding groove III, and the connecting block at the bottom of the moving rod drives the sliding block to slide through the sliding groove III.

[0010] As a preferred technical scheme of the application, the upper and lower ends of the sliding block are provided with notches, the width of the notches is greater than the diameter of the extrusion mechanism, and the width and height of the fixed block are both less than the height and width of the sliding block close to the fixed block.

[0011] As a preferred technical scheme of the application, the inner wall of the sliding block is elastically extended with elastic blocks on both sides, the two sides of the elastic blocks are rotatably connected with rollers, the top of the sliding rod is fixedly connected with a connecting ring, the middle part of the connecting ring penetrates through a connecting rod II, and the two ends of the connecting rod II are fixedly connected with clamping blocks.

[0012] As a preferred technical scheme of the application, the two ends of the connecting rod II are both fixedly connected with bevel gears II, the bevel gears II are located on one side of the connecting ring, the surface of the bevel gears II is engaged with bevel gears I, the top of the bevel gears I is fixedly connected with a connecting rod I, and the connecting rod I is slidably installed on the top of the sliding block through the connecting ring.

[0013] As a preferred embodiment of the present invention, a telescopic rod is slidably connected to the bottom of the fixed block, a groove I is provided on the surface of the extrusion mechanism and the telescopic rod, a limit block is fixedly connected to the inner wall of the fixed block, the bottom of the extrusion mechanism is sleeved inside the telescopic rod, and a spring III is fixedly connected to the bottom of the extrusion mechanism, with the spring III located inside the telescopic rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Gear I rotates and meshes with the moving rod, pushing the moving rod and slider towards the large pulley of the equipment, expanding the coverage angle of the large pulley. At the same time, the coverage angle of the small pulley also increases accordingly. This ensures that the pulleys are always in contact with the conveyor belt and are in a taut state. Furthermore, by continuously moving the tensioning wheel towards the large pulley, the tensioning space of the bed conveyor belt is increased. This prevents the conveyor belt from breaking due to insufficient space when the tensioning wheel continuously pushes the bed conveyor belt, thus reducing the frequency of conveyor belt replacement and maximizing the utilization rate of the conveyor belt during operation.

[0016] 2. When the locking block passes the spring block, the spring block is ejected again by the internally installed spring II. When the tension wheel stops moving, the locking block is locked on one side of the spring block, which can fix the distance moved by the tension wheel. At the same time, during the operation of the conveyor belt, it can reduce the back-and-forth shaking of the tension wheel on the surface of the conveyor belt caused by the deformation of spring I, and ensure the stability of the equipment during operation.

[0017] 3. The extrusion mechanism and the telescopic rod are squeezed together, causing the extrusion mechanism and the telescopic rod to slide out of the limiting block through the sliding groove I inside the fixed block. Then, the tensioning wheel is rotated so that the tensioning wheel and the slider are in a folded state, which makes it easier for workers to have a certain operating space when changing the conveyor belt. The limiting block is stuck inside the sliding groove I, which can prevent the tensioning wheel and the conveyor belt from shifting due to long-term friction. This ensures that the angle of the tensioning wheel is always at the same horizontal line as the slider. Attached Figure Description

Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0029] Embodiment one,

[0030] Please refer to Figures 1-3 and Figure 5As shown, a kind of bar insulator processing conveying belt tensioning adjusting device, including base 1, the bottom of base 1 is rotatably connected with workbench 2 by rotating wheel and conveying belt, conveying disc for conveying insulator is connected at the bottom of workbench 2;Conveying belt tensioning adjusting device further includes extrusion mechanism 3, the middle part of extrusion mechanism 3 is rotatably connected with fixed block 308, the middle part of extrusion mechanism 3 and the position opposite to fixed block 308 is rotatably connected with tensioning wheel 301, the both sides surface of fixed block 308 is fixedly connected with slide rod 305, the back of base 1 is slidably connected with sliding block 302, and the inner wall of sliding block 302 is slidably connected with slide rod 305 and sliding block 302, the surface of fixed block 308 is fixedly connected with spring I 306, the end of spring I 306 is fixedly connected with the inner wall of sliding block 302, the both sides surface of sliding block 302 is provided with sliding groove II;Tensioning wheel 301 is placed on the surface of conveying belt, extrusion mechanism 3 is U-shaped, and connecting rod III 318 is penetrated through sliding groove II, one end of connecting rod III 318 close to sliding block 302 is fixedly connected with slide rod 305, and the surface of connecting rod III 318 is sleeved with slidingly connected rack 303;One end of rack 303 is engaged with gear II 319, gear II 319 is rotatably connected between the bottom and base 1, gear I 304 is fixedly connected at the top of gear II 319, and gear I 304 is located at the top of base 1 by penetrating slot;The surface of gear I 304 is engaged with moving rod 320, the bottom of moving rod 320 is fixedly connected with the top of sliding block 302 through connecting block, and the top of the back of base 1 is provided with sliding groove III.

[0031] When working, the surface of conveying belt is placed on the surface of tensioning wheel 301, when conveying belt is loosened during use, tensioning wheel 301 is continuously pushed to the direction of conveying belt by the deformation expansion of spring I 306, so that conveying belt returns to tight state, when tensioning wheel 301 is continuously moved to the direction of conveying belt, slide rod 305 is moved to the same direction with tensioning wheel 301 on the both sides of the inner wall of sliding block 302, connecting rod III 318 and rack 303 are also moved to the same direction with slide rod 305 and tensioning wheel 301, rack 303 and gear II 319 are engaged to drive gear I 304 to rotate, gear I 304 is engaged with moving rod 320 to push moving rod 320 and sliding block 302 to move to the direction of large pulley, the covering angle of large pulley is expanded, and the covering angle of small pulley is also increased correspondingly, so that pulley is always in tension state with conveying belt, and the tensioning space of conveying belt is increased by continuously moving tensioning wheel 301 to the direction of large pulley, so that the breakage of conveying belt caused by friction between conveying belts due to insufficient space when tensioning wheel 301 continuously pushes and presses conveying belt is avoided, the replacement frequency of conveying belt is reduced, and the utilization rate of conveying belt reaches maximum during work;

[0032] When the tensioning wheel 301 continuously moves towards the direction of approaching the conveying belt, the clamping block 316 also moves in the same direction. When the clamping block 316 passes through the elastic block 312, the elastic block 312 is squeezed and retracted into the interior of the sliding block 302 by the contact between the clamping block 316 and the elastic block 312. When the clamping block 316 passes through the elastic block 312, the elastic block 312 is popped out again by the spring II arranged in the interior. When the tensioning wheel 301 stops moving, the clamping block 316 is clamped on one side of the elastic block 312, so that the distance moved by the tensioning wheel 301 can be fixed. At the same time, the conveying belt can reduce the back and forth shaking of the tensioning wheel 301 on the surface of the conveying belt due to the deformation of the spring I 306 in the working process, so as to ensure the stability of the equipment in the running process.

[0033] Embodiment two,

[0034] Please refer to Figure 4 and Figures 6-9 As a specific embodiment of the present application, the connecting block at the bottom of the moving rod 320 drives the sliding block 302 to slide through the sliding groove III. The upper and lower ends of the sliding block 302 are provided with notches, the width of the notches is greater than the diameter of the squeezing mechanism 3, and the width and height of the fixed block 308 are both less than the height and width of the position of the sliding block 302 close to the fixed block 308. The inner wall of the sliding block 302 is elastically extended with elastic blocks 312 on both sides, the both sides of the elastic blocks 312 are rotatably connected with rollers 3121, the top of the sliding rod 305 is fixedly connected with a connecting ring 317, the connecting ring 317 is penetrated by a connecting rod II 315 in the middle, and the both ends of the connecting rod II 315 are fixedly connected with clamping blocks 316. The both ends of the connecting rod II 315 are fixedly connected with bevel gears II 314, the bevel gears II 314 are located on one side of the connecting ring 317, the surface of the bevel gears II 314 is engaged with bevel gears I 313, the top of the bevel gears I 313 is fixedly connected with a connecting rod I 310, and the connecting rod I 310 is slidably installed on the top of the sliding block 302 through a connecting ring. The bottom of the fixed block 308 is slidably connected with a telescopic rod 3084, the surface of the squeezing mechanism 3 and the telescopic rod 3084 is provided with a sliding groove I 3082, the inner wall of the fixed block 308 is fixedly connected with a limiting block 3081, the bottom of the squeezing mechanism 3 is sleeved in the interior of the telescopic rod 3084, and the bottom of the squeezing mechanism 3 is fixedly connected with a spring III 3083, and the spring III 3083 is located in the interior of the telescopic rod 3084.

[0035] When the conveying belt needs to be replaced because it is too loose, the rotating connecting rod I 310 drives the bevel gears I 313 to engage with the bevel gears II 314, so that the connecting rod II 315 and the clamping block 316 are turned over by 180°. When the tensioning wheel 301 moves towards the interior of the sliding block 302, the clamping block 316 moves along the elastic block 312 and the curved surface contacts with the elastic block 312, so as to avoid the jamming when moving towards the interior of the sliding block 302. When the new conveying belt is replaced, the tensioning wheel 301 and the sliding block 302 can be restored to the original position and away from the large pulley because the new conveying belt has a better tensioning state.

[0036] When the conveying belt is replaced, the extrusion mechanism 3 and the telescopic rod 3084 can be manually extruded, so that the extrusion mechanism 3 and the telescopic rod 3084 slide in the fixed block 308 inside the sliding groove I 3082 and exit the limiting block 3081, and then the tensioning wheel 301 is rotated to be in a folded state between the tensioning wheel 301 and the sliding block 302, so as to facilitate the workers to have a certain operation space when replacing the conveying belt, and the limiting block 3081 is clamped inside the sliding groove I 3082, which can avoid the deviation phenomenon caused by long-time friction between the tensioning wheel 301 and the conveying belt, and can make the angle of the tensioning wheel 301 always be in the same horizontal line with the sliding block 302, thereby ensuring the normal operation of the equipment.
