Description

Technical Field

[0001] This utility model relates to the field of conveying technology, and in particular to a conveyor with easily replaceable rollers. Background Technology

[0002] In existing roller conveyors, the rollers are connected to the scissor mechanism via connecting shafts at both ends. The connecting shafts are secured with nuts, thereby ensuring the stability and reliability of the rollers during use.

[0003] However, this design makes disassembly and replacement quite complicated when the rollers fail. First, the scissor lift mechanism needs to be retracted, then the nut removed, and finally the scissor arms must be pried open to remove the rollers from the connection holes. Because the scissor arms are rigid structures, disassembly is very difficult, and workers often need to disassemble multiple scissor arms and roller structures to complete the replacement. This process is not only time-consuming and labor-intensive, but can also lead to prolonged equipment downtime and reduced production efficiency.

[0004] Furthermore, the disassembly process is cumbersome and requires specific tools, increasing the labor intensity and operational difficulty for workers. In actual production environments, this structural design limits the rapid replacement of rollers, increases maintenance costs, and enhances the complexity of equipment maintenance. Therefore, how to improve this design and enhance the efficiency of roller disassembly and replacement has become a crucial issue that urgently needs to be addressed in current roller conveyor systems. Utility Model Content

[0005] The purpose of this invention is to provide a conveyor that facilitates roller replacement, thereby solving the problem of cumbersome roller disassembly operations mentioned in the background art.

[0006] This utility model is achieved through the following technical solution:

[0007] The conveyor is designed for easy roller replacement. The main body is a roller conveyor, and the roller conveyor is equipped with a scissor mechanism. The scissor mechanism is mainly formed by connecting several scissor arms, connecting rods, and rollers.

[0008] The bottom and middle joints of the scissor arms are connected by a connecting rod, while the top joint is connected by a roller.

[0009] The roller is rotatably connected to the connecting shaft, and the two ends of the connecting shaft are provided with threaded structures; the connecting shaft passes through the scissor arm and the roller is fixed to the scissor arm by nuts;

[0010] The feature is that: the top of any scissor arm is provided with a U-shaped shallow opening, the extension direction of the U-shaped shallow opening forms a certain angle with the extension direction of the scissor arm; and the opening deflection direction of the U-shaped shallow opening in any two scissor arms that intersect at the top is opposite; so that the U-shaped shallow openings of the two scissor arms that intersect at the top are staggered and overlapped to form a connection port for the connecting shaft; the connecting shaft of the roller passes through the connection port and the inner and outer sides of the connection port are clamped to the scissor arm 111 by nuts that cooperate with the connecting shaft.

[0011] Compared with previous technologies, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model simplifies the disassembly process of the rollers and avoids cumbersome steps. By forming a connection port through the staggered overlapping of two U-shaped shallow openings on the scissor arm, and by limiting the forming connection shaft of the rollers through the connection port, workers can quickly and easily disassemble the rollers, greatly reducing maintenance time and improving the availability of the production line.

[0013] 2. This utility model reduces the number of components that need to be removed during the disassembly process. Workers only need to disassemble the connecting mechanism of the roller to complete the roller replacement, which significantly improves work efficiency, reduces equipment downtime, and lowers maintenance costs.

[0017] Labeling explanation: 1 Roller conveyor, 11 Scissor mechanism, 111 Scissor arm, 112 U-shaped shallow opening, 2 Roller, 21 Connecting shaft. Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description:

[0019] like Figures 1 to 3 As shown, the conveyor that facilitates roller replacement is mainly a roller conveyor 1. The roller conveyor 1 is equipped with a scissor mechanism 11, which is mainly formed by connecting several scissor arms 111, connecting rods and rollers 2.

[0020] The bottom and middle joints of the scissor arms 111 are connected by a connecting rod, and the top joint is connected by a roller 2.

[0021] The roller 2 is rotatably connected to the connecting shaft 21, and the two ends of the connecting shaft 21 are provided with threaded structures; the connecting shaft 21 passes through the scissor arm 111 and the roller 2 is fixed to the scissor arm 111 by means of a nut;

[0022] Each scissor arm 111 has a U-shaped shallow opening 112 at its top. The opening of the U-shaped shallow opening 112 extends at an angle to the extension direction of the scissor arm 111. Furthermore, the openings of the U-shaped shallow openings 112 in any two scissor arms 111 that intersect at their tops are deflected in opposite directions. This causes the U-shaped shallow openings 112 of the two scissor arms 111 that intersect at their tops to overlap and form a connection port for the connecting shaft 21. The connecting shaft 21 of the roller 2 passes through the connection port, and the inner and outer sides of the connection port are clamped to the scissor arm 111 by nuts that mate with the connecting shaft 21.

[0023] It should be noted that this utility model has two core designs;

[0024] Design point 1: The opening for fixing the connecting shaft 21 is a U-shaped shallow opening 112. The reason for designing a shallow opening is mainly to allow the connecting shaft to touch the bottom and achieve a limit during installation. Generally, the depth here is 3-5cm.

[0025] Design point 2 concerns the fact that the extension direction of the U-shaped shallow opening 112 forms a certain angle with the extension direction of the scissor arm 111; and the deflection direction of the U-shaped shallow opening 112 in any two scissor arms 111 that intersect at the top is opposite. This design is mainly to prevent the connecting shaft from detaching. In this invention, two design schemes exist. The other scheme, with the U-shaped opening, additionally uses a fixing plate for fixation. If the U-shaped opening is too deep, the roller may sink. Therefore, without the fixing plate, a shallow opening design is used to limit the depth and ensure the roller does not sink. However, initially, the extension direction of the U-shaped shallow opening 112 was consistent with the extension direction of the scissor arm 111. During actual testing, it was found that during the stretching and bending of the conveyor, one side of the roller was prone to warping and loosening. Therefore, the U-shaped shallow opening 112 is deflected, so that the U-shaped shallow openings 112 of the two scissor arms 111 that intersect at the top overlap to form the connection port of the connecting shaft 21, thus limiting the connection of the connecting shaft.

[0026] It should be noted that the roller conveyor 1 is a conventional technology. In order to achieve transmission, it is necessary to consider setting a belt between the adjacent rollers 2 and the scissor arm 111 to achieve transmission. Since this is a conventional technology, it has not been described in detail. The scissor mechanism 11 is mainly used to extend the transmission of the roller conveyor 1.

[0027] The opening deflection direction of the U-shaped shallow opening 112 is consistent with the tilt direction of the corresponding scissor arm 111, ensuring the forming effect of the connection joint.

[0028] Furthermore, the angle formed by the extension direction of the U-shaped shallow opening 112 and the extension direction of the scissor arm 111 is between 15-30°. This angle can be limited according to the model, but currently it is mainly designed to be between 15-20°.

[0029] Furthermore, the roller conveyor 1 is also equipped with a connecting rod for connecting the casters and several casters, which facilitates the movement of the roller conveyor 1. This structure is not a critical aspect of this invention and is therefore not included in the claims.

[0030] Although this utility model has been illustrated and described using specific embodiments and alternative methods, it should be understood that various changes and modifications are permitted as long as they do not depart from the spirit and scope of this utility model. Therefore, it should be understood that this utility model is not limited in any sense except by the appended claims and their equivalents.
