Description

Technical Field

[0001] This utility model relates to the field of roller conveyor belt technology, specifically a transition rod telescopic assembly based on a telescopic roller. Background Technology

[0002] A roller conveyor belt is a device consisting of rollers, bearings, and a frame, primarily used in assembly lines, automated equipment, and logistics systems to transport goods. It uses the rotation of the rollers to propel goods along a pre-set path, thus achieving automated and efficient material handling.

[0003] Most existing roller conveyors use a combination of drive rods and transition rods for transport. However, they often have the following problems during use: 1. The spacing between the internal transition rods of existing roller conveyors is fixed, and the overall length of the roller conveyor is fixed, making it inconvenient to adjust the overall length of the roller conveyor. Although the spacing between the transition rods of existing telescopic roller conveyors can be stretched to adjust the overall length of the conveyor, when the spacing between two transition rods is large, small objects are prone to falling out of the gap, making it inconvenient to transport small objects; 2. The fixed length of the internal transition rods of existing roller conveyors can cause narrow objects to deviate due to their large width, and may prevent the transport of wide objects due to insufficient width. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

Two support plates are rotatably connected to both ends of the transition rod. A connecting plate is hinged to the top of each support plate, and the bottom of the connecting plate is slidably connected to the side wall of an adjacent support plate near its bottom. The middle portion of every two adjacent connecting plates is hinged to each other, and an auxiliary roller is provided between every two transition rods. In normal operation, the auxiliary roller is located above the transition rod, and objects are conveyed through it. When the conveyor belt needs to be extended, the two transition rods are pulled apart, and the auxiliary roller moves downward until it is flush with the top of the transition rod. Objects are then conveyed through the transition rod and the top of the auxiliary roller. This allows for the extension of the conveyor belt without affecting the conveying of small objects.

[0007] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0008] A telescopic transition rod assembly based on a telescopic roller, comprising:

[0009] A transition rod, which is cylindrical, has rubber rings at both ends to increase the anti-slip performance of the transition rod.

[0010] A folding assembly includes two support plates rotatably connected to both ends of a transition rod and a connecting plate hinged to the top of the support plates. The top of the connecting plate is hinged to the side wall of one of the support plates, and the bottom of the connecting plate is slidably connected to the side wall of the other support plate near the bottom.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] This invention provides a telescopic transition rod assembly based on a telescopic roller. Two support plates are rotatably connected to both ends of the transition rod. A connecting plate is hinged to the top of each support plate, and its bottom is slidably connected to the side wall of an adjacent support plate near its bottom. The middle portion of every two adjacent connecting plates is hinged together. An auxiliary roller is provided between every two transition rods. In normal operation, the auxiliary roller is located above the transition rod, and objects are conveyed through it. When the conveyor belt needs to be extended, the two transition rods are pulled apart, and the auxiliary roller moves downward until it is flush with the top of the transition rod. Objects are then conveyed through the transition rod and the top of the auxiliary roller. This design allows for the extension of the conveyor belt without affecting the conveying of small objects.

[0026] Example 1

[0027] Regarding the problem 1 to be solved above: In existing roller conveyors, the spacing between the internal transition bars is fixed, and the overall length of the roller conveyor is fixed, making it inconvenient to adjust the overall length of the roller conveyor. In existing telescopic roller conveyors, although the spacing between the transition bars can be stretched to adjust the overall length of the conveyor, when the spacing between two transition bars is large, small objects are prone to falling out of the gap, making it inconvenient to transport small objects.

[0028] The solution is as follows: This embodiment of the transition rod telescopic assembly based on telescopic roller includes a transition rod 100, a folding assembly 200 and an auxiliary roller 300.

[0029] The transition rod 100 is cylindrical, with rubber rings at both ends to increase its anti-slip performance. The folding assembly 200 includes two support plates 210 rotatably connected to both ends of the transition rod 100 and a connecting plate 220 hinged to the top of the support plates 210. The top of the connecting plate 220 is hinged to the side wall of one of the support plates 210, and the bottom of the connecting plate 220 is slidably connected to the side wall of the other support plate 210 near the bottom. Each pair of connecting plates 220 is hinged at the midpoint by bolts 230, forming an X-shape between two adjacent support plates 210. The support plates 210 are generally strip-shaped, and the length of the connecting plate 220 is the same as the length of the support plates 210. A guide groove 240 is provided on the side wall of the support plate 210, and a guide block 250 is installed at the bottom of the connecting plate 220, slidably connected to the guide groove 240. Inside the 40, one of the support plates 210 has an ear plate 270 installed on its side wall. The ear plate 270 has a bolt hole 280 on its side wall. The ear plate 270 and the folding assembly 200 are fixed to the outside by bolts passing through the bolt hole 280, so that the folding assembly 200 can be installed and fixed. When it is necessary to adjust the distance between the two transition rods 100, the two adjacent support plates 210 are pulled closer or further apart. When the two support plates 210 are further apart, the guide block 250 slides upward in the guide groove 240, and the two connecting plates 220 hinged by bolts 230 flip up, and the two transition rods 100 move further apart. When the two support plates 210 are closer together, the guide block 250 slides downward in the guide groove 240, and the two transition rods 100 move closer together, so as to facilitate the adjustment of the distance between each pair of transition rods 100, and thus adjust the total length of the conveyor belt.

[0030] There are multiple auxiliary rollers 300, each located between every two transition bars 100. Two second connecting plates 310 are hinged to the side of each auxiliary roller 300, and the other ends of the two second connecting plates 310 are respectively hinged to the side walls of two intersecting connecting plates 220. In the initial state, the auxiliary roller 300 is located above the transition bar 100, and the object is conveyed through the top of the auxiliary roller 300. When every two support plates 210 move away from each other, the two intersecting connecting plates 220 flip open, pulling the two second connecting plates 310 to flip open in reverse, and the auxiliary roller 300 moves downward until the top of the auxiliary roller 300 is flush with the top of the transition bar 100. The object is conveyed through the auxiliary roller 300 and the transition bar 100, preventing small objects from falling between the two rollers during conveying due to the increased size between the two rollers when the conveyor belt is stretched.

[0031] Example 2

[0032] Regarding the problem 2 mentioned above: the existing roller conveyor belt has a fixed length of internal transition rod. When conveying narrow objects, the objects are prone to deviation because the width is too large. When conveying wide objects, the width is insufficient, which may prevent the objects from being conveyed.

[0033] The solution is as follows: This embodiment of the transition rod telescopic assembly based on telescopic rollers also includes a knob 400.

[0034] Side plates 290 are installed on the side walls of the two outermost support plates 210. A knob 400 is rotatably connected to the side wall of one of the side plates 290. A threaded rod 410 is installed on the side wall of the knob 400. A fixing rod 420 is installed on the side wall of the other side plate 290. A threaded hole 430 is opened at the side end of the fixing rod 420. The threaded rod 410 rotates into the threaded hole 430. The transition rod 100 includes a first rod body 110 and a second rod body 120. The first rod body 110 and the second rod body 120 are rotatably connected to the tops of the two opposing support plates 210. A slot 130 is opened on the side wall of the first rod body 110. A sliding rod 140 is installed on the side wall of the second rod body 120. The sliding rod 140 is located inside the slot 130. A cross-shaped insert rod 150 is installed inside the slot 130. A cross-shaped insertion hole 160 is provided on the side end of 140. The cross-shaped insertion rod 150 extends into the cross-shaped insertion hole 160. When it is necessary to adjust the length of the transition rod 100, the knob 400 is rotated to drive the threaded rod 410 to rotate. The screw structure pushes the fixed rod 420 and another support plate 210 away from their corresponding support plate 210. Then the first rod 110 and the second rod 120 move away from each other. When the first rod 110 and the second rod 120 move away from each other, the slide rod 140 slides inside the slot 130, and the cross-shaped insertion rod 150 slides inside the cross-shaped insertion hole 160 until the adjustment is in place. When the first rod 110 or the second rod 120 rotates, the cross-shaped insertion rod 150 cooperates with the slide rod 140 to drive the first rod 110 and the second rod 120 to rotate synchronously.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
