Description

Technical Field

[0001] The utility model relates to the technical field of material transportation, in particular to a conveying roller capable of preventing jamming. Background Art

[0002] In production activities, most materials need manual or mechanical transportation to achieve loading or transfer within the workshop. This is generally achieved using structures such as conveyor belts and conveyor rollers. Compared with conveyor belts, conveyor rollers can transport larger and heavier materials, have strong load-bearing capacity and stable transportation. Therefore, conveyor rollers are used in the production of some mechanical equipment to transfer materials such as metal sheets.

[0003] The existing conveying rollers do not realize transfer by a single roller, but a number of rollers are arranged linearly and distributed equidistantly on a conveying track. The conveying rollers are rotationally or movably connected to the inner wall of the conveying track, and the material on the surface of the conveying rollers is transported through active or passive rotation.

[0004] However, during the actual use of the above-mentioned equipment, there are gaps between the conveying rollers. Some metal sheet materials may shake due to friction or other external forces during transportation. During the loading and unloading process, the ends of the sheets may be obliquely inserted into the gaps between the rollers, causing the conveying rollers to get stuck, which in turn causes the material transfer system to malfunction. In view of this, we propose a conveying roller that can prevent getting stuck. Utility Model Content

[0005] The utility model aims to provide a conveying roller which can prevent jamming, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a conveying roller capable of preventing jamming, comprising a main shaft, an outer sleeve is sleeved on the arc-shaped outer wall of the main shaft, and the outer sleeve is rotatably connected to the main shaft, and an anti-jamming mechanism is arranged inside the outer sleeve, and the anti-jamming mechanism comprises:

[0007] A swing groove, a swing groove is provided on the arc-shaped outer wall of the outer sleeve, a fixed sleeve is sleeved on the arc-shaped outer wall of the main shaft, and the fixed sleeve and the main shaft are fixedly connected, a connecting rod is fixedly installed on the outer wall of the end of the fixed sleeve, and a guide rod is rotatably installed on the inner wall of one end of the connecting rod away from the fixed sleeve;

[0008] A rotating rod is rotatably installed on the inner wall of the swing groove, an arc-shaped belt plate passes through the rotating rod, and the arc-shaped belt plate is fixedly connected to the rotating rod, a spiral spring is sleeved on the arc-shaped outer wall of the rotating rod, and an arc-shaped strip is fixedly installed on the outer wall of the arc-shaped belt plate on one side close to the main shaft.

[0009] Preferably, the number of the swing grooves is arranged in several groups, and the several groups of swing grooves are evenly distributed in a circular array on the arc-shaped outer wall of the outer sleeve, and a blocking bar is arranged on the bottom inner surface of the swing groove so that the arc-shaped belt plate can only rotate toward the side away from the center of the outer sleeve and cannot rotate to the inside of the outer sleeve.

[0010] Preferably, there are two groups of guide rods, and both groups of guide rods are horizontally mirrored on the left and right sides of the fixed cylinder, so that the arc-shaped belt plate moving to the gap between two adjacent groups of conveying rollers will be pushed by the guide rods and expand outward.

[0011] Preferably, a circular hole with a diameter larger than the outer diameter of the spiral spring is opened on the inner wall of the end of the swing groove, and the two ends of the spiral spring are respectively fixedly connected to the bottom inner wall of the circular hole and the arc-shaped outer wall of the rotating rod. Due to the elastic force of the spiral spring, the rotating rod drives the arc-shaped belt plate to fit tightly on the bottom inner surface of the swing groove.

[0012] Preferably, a guiding mechanism is arranged inside the end of the arc-shaped belt plate away from the rotating rod, and the guiding mechanism includes an arc-shaped groove. An arc-shaped groove is opened on the arc-shaped outer surface of the arc-shaped belt plate away from the inner wall of the outer sleeve. A round rod is rotatably installed on the inner wall of the end of the arc-shaped belt plate away from the rotating rod, and a small roller is fixedly installed on the round rod, and a convex belt is fixedly installed on the arc-shaped outer wall of the small roller.

[0013] Preferably, the convex belt is arranged in a wave shape on the arc-shaped outer surface of the small roller to increase the friction coefficient between the small roller and the external transfer material, thereby ensuring the stability of the material during transmission.

[0014] Compared with the prior art, the utility model provides a conveying roller that can prevent jamming, which has the following beneficial effects:

[0015] 1. The anti-jamming conveying roller is provided with an anti-jamming mechanism, which cooperates with the guide rods horizontally arranged on the left and right sides of the main shaft. When the outer sleeve rotates with the material transportation, the arc strips corresponding to the arc-shaped belt plate intermittently contact and squeeze the guide rods, so as to force the arc-shaped belt plate moving between two adjacent groups of conveying rollers to deflect away from the center of the outer sleeve with the rotating rod as the rotation axis, so as to fill the gap between the two adjacent groups of conveying rollers, and drive the arc-shaped belt plate to drive the material that may enter the gap outward through the rotation of the outer sleeve, so as to avoid the material from getting stuck during the transmission process.

[0016] 2. The anti-stuck conveying roller is provided with a guiding mechanism. When the arc-shaped belt plate is guided by the guide rod and the arc-shaped strip and expanded outward, it cooperates with the freely rotatable small roller and the convex belt arranged on the surface thereof, so as to ensure the friction force during contact to push it to avoid jamming, and at the same time, prevent the material in the gap between the conveying rollers from being further jammed when being pushed outward.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a conveying roller that can prevent jamming, including a main shaft 1, an outer sleeve 2 is sleeved on the arc-shaped outer wall of the main shaft 1, and the outer sleeve 2 is rotatably connected to the main shaft 1, and an anti-jamming mechanism 3 is arranged inside the outer sleeve 2, and the anti-jamming mechanism 3 includes a swing groove 31, a fixed cylinder 32, a connecting rod 33, a guide rod 34, a rotating rod 35, an arc-shaped belt plate 36, a spiral spring 37 and an arc-shaped strip 38.

[0024] In one embodiment of the utility model, a swing groove 31 is provided on the arc-shaped outer wall of the outer sleeve 2, a fixed cylinder 32 is sleeved on the arc-shaped outer wall of the main shaft 1, and the fixed cylinder 32 is fixedly connected to the main shaft 1, a connecting rod 33 is fixedly installed on the outer wall of the end of the fixed cylinder 32, and a guide rod 34 is rotatably installed on the inner wall of the end of the connecting rod 33 away from the fixed cylinder 32, a rotating rod 35 is rotatably installed on the inner wall of the swing groove 31, the rotating rod 35 passes through an arc-shaped belt plate 36, and the arc-shaped belt plate 36 is fixedly connected to the rotating rod 35, a volute spring 37 is sleeved on the arc-shaped outer wall of the rotating rod 35, and an arc strip 38 is fixedly installed on the outer wall of the arc-shaped belt plate 36 on the side close to the main shaft 1.

[0025] Furthermore, the main shaft 1 is fixedly connected to the inner wall of the external transport track to provide a horizontal installation environment for the outer sleeve 2. At the same time, due to the rotational connection between the outer sleeve 2 and the main shaft 1, the friction between the material and the outer sleeve 2 can be reduced by the rotation of the outer sleeve 2 during the transportation of the material on the top of the outer sleeve 2, so as to facilitate the transportation of metal sheet materials. In addition, the number of swing grooves 31 is arranged in several groups, and several groups of swing grooves 31 are evenly distributed in a circular array on the arc-shaped outer wall of the outer sleeve 2, and blocking strips are arranged on the bottom inner surface of the swing groove 31, so that the arc-shaped belt plate 36 can only rotate toward the side away from the center of the outer sleeve 2, and will not rotate to the inside of the outer sleeve 2, resulting in a cavity on the arc-shaped outer surface of the outer sleeve 2, thereby affecting the metal For normal transportation of plates, specifically, there are two groups of connecting rods 33, and each group of connecting rods 33 is provided with two, the two connecting rods 33 are mirror-imaged on the left and right sides of the fixed cylinder 32, and the two groups of connecting rods 33 are respectively provided at both ends of the fixed cylinder 32. Specifically, there are two groups of guide rods 34, and the two groups of guide rods 34 are horizontally mirror-imaged on the left and right sides of the fixed cylinder 32, so that the arc belt plate 36 moving to the gap between the two adjacent groups of conveying rollers will be pushed by the guide rod 34 and expand outward to fill the gap between the two adjacent groups of conveying rollers, and the arc belt plate 36 is driven by the rotation of the outer sleeve 2 to drive the material that may enter the gap outward to avoid the material from getting stuck during the transmission process.

[0026] In addition, a circular hole with a diameter larger than the outer diameter of the spiral spring 37 is opened on the inner wall of the end of the swing groove 31, and the two ends of the spiral spring 37 are respectively fixedly connected to the bottom inner wall of the circular hole and the arc-shaped outer wall of the rotating rod 35. Specifically, in the initial state, due to the elastic force of the spiral spring 37, the rotating rod 35 drives the arc-shaped belt plate 36 to fit tightly on the bottom inner surface of the swing groove 31, and always has a tendency to deflect toward the center of the outer sleeve 2. As a result, with the cooperation of the guide rod 34 and the arc strip 38, when the arc-shaped belt plate 36 deflects outward with the rotating rod 35 as the rotation center and then breaks away from the contact with the guide rod 34, the rotating rod 35 drives the arc-shaped belt plate 36 to adhere to the swing groove 31, so that the arc-shaped outer surface of the outer sleeve 2 maintains a complete arc surface, so as to reduce obstacles to the transported materials and facilitate the transportation of materials.

[0027] In an embodiment of the utility model, a guiding mechanism 4 is provided inside the end of the arc-shaped belt plate 36 away from the rotating rod 35, and the guiding mechanism 4 includes an arc-shaped groove 41. The arc-shaped groove 41 is provided on the arc-shaped outer surface of the arc-shaped belt plate 36 away from the inner wall of the outer sleeve 2. A round rod 42 is rotatably installed on the inner wall of the end of the arc-shaped belt plate 36 away from the rotating rod 35. A small roller 43 is passed through and fixedly installed on the round rod 42, and a convex belt 44 is fixedly installed on the arc-shaped outer wall of the small roller 43.

[0028] Specifically, the number of arc grooves 41 is set in multiple groups, and the multiple groups of arc grooves 41 are evenly distributed on the arc outer surface of the arc belt plate 36 in a linear array, thereby increasing the contact between the outer sleeve 2 and the transported material to make the friction and driving force increase, and avoid the material from slipping when being transported on the conveyor roller. At the same time, the inner wall of the end of the arc belt plate 36 away from the rotating rod 35 is provided with a circular groove with a diameter greater than the outer diameter of the small roller 43, so that the small roller 43 can rotate freely in the circular groove. In addition, the number of small rollers 43 is set in multiple groups, and multiple groups of small rollers 43 is evenly distributed in a linear array on the inner wall of the end of the arc-shaped belt plate 36 away from the rotating rod 35. Furthermore, the convex belt 44 is arranged in a wave shape on the arc-shaped outer surface of the small roller 43, so that when the outer sleeve 2 rotates to transport materials, the arc-shaped belt plate 36 is guided by the guide rod 34 and the arc strip 38 and expands outward. Through the freely rotatable small roller 43 and the convex belt 44 arranged on the surface thereof, the friction force during contact is ensured to push it to avoid jamming, and at the same time, the material in the gap between the conveying rollers is prevented from being further jammed when it is pushed outward.

[0029] In the utility model, when in use, the main shaft 1 is fixedly installed on the inner wall of the external conveying track, and the main shaft 1 and the outer sleeve 2 are ensured to be arranged horizontally. When transporting materials, the friction between the materials and the outer sleeve 2 will drive the outer sleeve 2 to rotate on the main shaft 1. As the outer sleeve 2 and the main shaft 1 move relative to each other, the arc strip 38 corresponding to the arc strip 36 in the swinging groove 31 intermittently contacts and squeezes the guide rod 34, forcing the arc strip 36 moving between the two adjacent groups of conveying rollers to deflect away from the center of the outer sleeve 2 with the rotating rod 35 as the rotation axis, so as to fill the gap between the two adjacent groups of conveying rollers, and drive the arc strip 36 to drive the materials that may enter the gap outward through the rotation of the outer sleeve 2, so as to avoid the materials from getting stuck during the transmission process.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
