Description

Technical Field

[0001] The utility model belongs to the technical field of protective structures, in particular to a protective structure for a conveyor belt. Background Art

[0002] The conveyor belt protection structure is an important component of industrial automation and material handling systems. Its design purpose is to protect the conveyor belt system from external damage, ensure operational safety, and prevent material scattering and personal injury.

[0003] During the transportation of boxes on the conveyor belt, the boxes may shift due to being touched and collide with the guardrail at the edge of the conveyor belt. During the entire transportation process, the boxes are easily damaged and the appearance of the boxes is affected. Therefore, in order to enable the boxes to be driven forward and reduce damage to the boxes during the transportation of the boxes, a protective structure for the conveyor belt is needed to solve the existing problem. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a protective structure for a conveyor belt. Through the cooperation between the transmission roller, the conveyor belt body and the limit frame, the box can be placed in the positive direction and transported forward, reducing the collision and friction between the corners of the box and the two side plates of the conveyor belt body, ensuring that the surface of the box is not damaged.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a protective structure for a conveyor belt, including a bracket, a conveyor belt body is installed on the bracket through a transmission roller, and multiple rotating rollers are symmetrically installed on both sides of the conveyor belt body, which are installed through an axis. The rotating rollers are evenly distributed in an array and rotate automatically when subjected to external force. Square tubes are also symmetrically installed on both sides of the bracket, and the upper and lower ends of the square tubes are penetrated by holes. The square tubes are vertically installed on the outer side walls of the four legs respectively, and limit frames are respectively penetrated in the square tubes on both sides. The limit frames are composed of arc-bent support rods, and the rod sleeves at the lower part of the limit frames are arranged in the square tubes. That is, when the rotating roller contacts the side wall of the box, it can assist the conveyor belt body in driving the box to be transported, that is, the limit frame limits the side wall of the box. When the angle connecting the two sides of the box contacts between two of the rotating rollers, when the conveyor belt body drives the box to move forward, the box will be shifted to the positive direction under the action of the box being transported and clamped by the two rotating rollers, and then move forward under the action of the limit frame, the conveyor belt body and the rotating roller to ensure that the box is placed in the positive direction.

[0006] A fastening bolt is installed through the square tube and the limiting frame sleeved inside the square tube, that is, the fastening bolt fixes the limiting frame.

[0007] A U-shaped plate is fixedly installed at the end of the bracket. The U-shaped plate is located at the transmission end of the conveyor belt body from bottom to top. The U-shaped plate is installed with a telescopic pneumatic cylinder. A baffle is arranged on the top of the telescopic pneumatic cylinder. The baffle is higher than the top of the conveyor belt, that is, the telescopic pneumatic cylinder drives the baffle to move up and down to block the transmission end of the conveyor belt body from bottom to top to prevent the box from falling. It is installed by threads and is detachable, which is convenient for removal or installation.

[0008] A layer of sponge pad is also installed around the surface of the rotating roller, that is, the sponge pad can protect the surface of the box. When the corners of the two sides of the box are stuck between the two rotating rollers, the surface of the sponge pad contacts the outer side of the box to ensure that the box is not damaged by hard objects.

[0009] The lower part of the limit frame is also penetrated with a plurality of through holes, and different through holes correspond to the square tubes respectively, so that the height of the limit frame can be adjusted conveniently.

[0010] An auxiliary plate is also fixedly mounted on the side wall of the bracket, and the rod at the lower part of the limiting frame passes through the auxiliary plate, that is, the auxiliary plate performs auxiliary limiting on the rod at the lower part of the limiting frame.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] First, when the corners connecting the two sides of the box come into contact with two of the rotating rollers, when the conveyor belt body drives the box forward, the box will be shifted to the positive direction under the action of the box being conveyed and clamped by the two rotating rollers, and then move forward under the action of the limit frame, the conveyor belt body and the rotating rollers, ensuring that the box is placed in the positive direction, avoiding continuous collision between the corners of the box and the two sides of the conveyor belt body, and protecting the box.

[0013] Secondly, the multiple perforations on the limit frame can make the perforations correspond to the square tubes respectively, and the limit frame can be adjusted in height using the fastening bolts to limit the middle or upper part of the side of the box, which is suitable for boxes of different heights.

[0014] Thirdly, the auxiliary plate can assist in limiting the rod at the lower part of the limiting frame, and the detachable installation of the thread can facilitate disassembly and installation. BRIEF DESCRIPTION OF THE DRAWINGS

In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0022] like Figure 1-3 As shown, a protective structure for a conveyor belt includes a bracket 101, a conveyor belt body 102 is installed on the bracket 101 through a transmission roller, and multiple rotating rollers 103 are symmetrically installed on both sides of the conveyor belt body 102, which are installed through an axis. The rotating rollers 103 are evenly distributed in an array and rotate automatically when subjected to external force. Square tubes 104 are symmetrically installed on both sides of the bracket 101, and the upper and lower ends of the square tubes 104 are penetrated by holes. The square tubes 104 are respectively vertically installed on the outer side walls of the four legs, and limit frames 105 are respectively penetrated in the square tubes 104 on both sides. The limit frames 105 are composed of arc-bent support rods, and the rod sleeves at the lower part of the limit frames 105 are arranged in the square tubes 104. That is, when the rotating roller 103 contacts the side wall of the box, it can assist the conveyor belt body 102 in driving the box to be transported, that is, the limiting frame 105 limits the side wall of the box. When the angle connecting the two side surfaces of the box contacts between two of the rotating rollers 103, when the conveyor belt body 102 drives the box to move forward, the box will be shifted to the positive direction under the action of the box being transported and clamped by the two rotating rollers 103, and then move forward under the action of the limiting frame 105, the conveyor belt body 102 and the rotating roller 103, ensuring that the box is placed in the positive direction.
