[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] A pipe loading and unloading mechanism, such as Figures 1-2As shown, the system includes a support frame 1 and support roller groups 2, a feeding assembly 3, a discharging assembly 4, and a first drive assembly 5, all mounted on the support frame 1. The support roller groups 2 are arranged on the support frame 1 to support the pipe, and the feeding assembly 3 pushes the pipe to move on the support roller groups 2, thereby feeding the pipe into the processing equipment. The discharging assembly 4 is located between two adjacent support roller groups 2, and the first drive assembly 5 controls the movement of the discharging assembly 4 to make the pipe leave the support roller groups 2.

[0018] In one embodiment, such as Figures 1-2 As shown, the support roller assembly 2 includes two mounting plates 21 and two support rollers 22. The two mounting plates 21 are symmetrically arranged, and the two support rollers 22 are arranged parallel between the two mounting plates 21, with both ends of the support rollers 22 rotatably connected to the mounting plates 21. The pipe is supported between the two support rollers 22, which serves to position the pipe.

[0019] In one embodiment, such as Figures 1-2 As shown, chamfers 221 are provided on both ends of the support roller 22. The pipe needs to move on each support roller group 2, and there is a gap between the support roller groups 2. The chamfers 221 ensure that the pipe can pass through each support roller group 2.

[0020] In one embodiment, such as Figures 1-2 As shown, the feeding assembly 3 includes a guide rail 31, a slider 32, a push rod 33, and a second drive assembly 34. The guide rail 31 is mounted on the bracket 1, the slider 32 is slidably mounted on the guide rail 31, the push rod 33 is connected to the slider 32, and the second drive assembly 34 is connected to the slider 32. The second drive assembly 34 drives the slider 32 to drive the push rod 33 to drive the tube to move axially.

[0021] In the above embodiments, such as Figures 1-2 As shown, the second drive assembly 34 includes a drive wheel 341, a driven wheel 342, a chain 343, and a drive motor 344. The drive wheel 341 and the driven wheel 342 are rotatably mounted on the bracket 1. The chain 343 connects the drive wheel 341 and the driven wheel 342. The drive motor 344 is connected to the drive wheel 341, and the slider 32 is connected to the chain 343. The reciprocating rotation of the drive motor 344 drives the slider 32, causing the push rod 33 to move reciprocally. This enables long-distance conveying and features a simple structure and low cost.

[0022] In the above embodiments, such as Figures 1-2 As shown, the second drive component 34 can also be a hydraulic cylinder, preferably a multi-stage hydraulic cylinder, thereby reducing the size of the equipment.

[0023] In one embodiment, such as Figures 1-2As shown, the feeding assembly 4 includes a hinge seat 41 and a material plate 42. The hinge seat 41 is fixed on the bracket 1, and the material plate 42 is hinged to the hinge seat 41. During feeding, the material plate 42 tilts up, lifting the tube away from the support roller group 2, and slides to one side along the material plate 42. After feeding, the material plate 42 returns to its original position.

[0024] In one embodiment, such as Figures 1-2 As shown, the second drive assembly 5 includes a connecting shaft 51, a hydraulic cylinder 52, and a drive block 53. The hydraulic cylinder 52 is mounted on the bracket 1, and the drive block 53 is connected to the hydraulic cylinder 52. The hydraulic cylinder 52 controls the reciprocating movement of the drive block 53. The drive block 53 has a through-hole obliquely arranged guide groove 531, and the connecting shaft 51 is located in the guide groove 531 and connected to the material plate 42. The connecting shaft 51 can connect multiple sets of feeding assemblies 4, thus enabling the movement of multiple sets of feeding assemblies 4 with one set of drive assembly. The hydraulic cylinder 52 horizontally pushes the drive block 53 to move, and after connection, the drive block 53 moves along the guide 531, thereby driving the material plate 42 to rotate around the hinge seat 41.

[0025] When using this utility model, such as Figures 1-2 As shown, the pipes are fed one by one onto the support rollers 2 by the feeding device. The second drive assembly 34 drives the push rod 33 to move the pipes in each support roller group 2 and feed them into the processing equipment. Then, the second drive assembly 34 moves in the reverse direction to reset the push rod 33. After the processing equipment finishes processing, the pipes are sent back to the support roller group 2. The first drive assembly 5 controls the material plate 42 to tilt up, and then the pipes slide down the material plate 42 to achieve unloading.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
