At this time, it indicates that the tails have completely exited the working range of the clamping and conveying component, and the clamping and conveying component stops working. Then the chain-type collecting component is lifted to drive the tails to rise. The tails move toward the horizontal tail collection direction as the chain rotates, and then fall into the prepared collection frame.

[0025] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0026] Please refer to Figure 1-4The present invention provides a pipe feeding and unloading conveying device, comprising a feeding frame 1, a conveying assembly 2, a limiting assembly 3, a clamping assembly 4 and a chain-type collecting assembly 5 installed in a lifting manner on the feeding frame 1, wherein the feeding frame 1 is a hollow long strip frame, one end of which is the feeding starting end and the other end is the feeding end end. The longitudinal direction from the feeding starting end to the feeding end end is the feeding direction. On the contrary, the longitudinal direction from the feeding end to the feeding starting end is the unloading direction. The conveying assembly 2 includes a plurality of conveying rollers 21 and a conveying motor 22 that drives the conveying rollers 21 to rotate in the same direction. The installation density of the plurality of conveying rollers 21 on the feeding frame 1 gradually increases along the feeding direction. The chain moving direction after the chain-type collecting assembly 5 lifts the pipe is perpendicular to the feeding direction of the conveying assembly 2, that is, the waste collection direction and the feeding direction are arranged perpendicular to each other. The clamping assembly 4 is fixedly installed on the feeding end of the feeding frame 1, and a first sensor and a second sensor (not shown in the figure) are provided on both sides of the clamping assembly 4 along the feeding direction.
[0027] It should be noted that when the chain-type collecting assembly 5 is raised to the highest position, the highest point of the top surface of the chain is higher than the highest point of the top surface of the conveying roller 21, so that the pipe can be lifted from the conveying roller 21. When the chain-type collecting assembly 5 is lowered to the lowest position, the highest point of the top surface of the chain is lower than the highest point of the top surface of the conveying roller 21, so that the pipe does not contact the chain, avoiding interference with the normal use of the conveying roller 21.
[0028] When the conveying device starts to convey the pipe, a long pipe enters the conveying equipment from the feeding starting end of the feeding frame 1 and is located on the conveying roller 21. The conveying roller 21 rotates and drives the pipe above it to move toward the direction close to the feeding end. During the movement, the limit component 3 limits the position of the pipe to prevent it from running off and falling. When the front end of the pipe moves to the position of the clamping component 4 and is sensed by the second sensor, the clamping component 4 clamps the front end of the pipe and conveys the pipe to continue moving along the feeding direction, so that the pipe is processed into the production target length by the cutting equipment in the rear section. When the remaining length of the pipe is not When the length is sufficient for the next cutting, the clamping and conveying component 4 stops working, and then the remaining tails of the pipe are conveyed in the reverse direction until the first sensor senses the front end of the tails. At this time, it indicates that the tails have completely exited the working range of the clamping and conveying component 4, and the clamping and conveying component 4 stops working. Then the chain-type collecting component 5 is lifted to drive the tails to rise. The tails move toward the horizontal tail collection direction as the chain rotates, and then fall into the prepared collection frame. Compared with the time-consuming and labor-intensive manual collection of tails, the conveying device of the utility model can automatically withdraw and collect the materials, which is more efficient and fast, saves labor costs, and effectively improves production efficiency.
[0029] It should be noted that the density of the conveying rollers 21 near the feeding end is high in order to accommodate the conveying of pipe tails of different lengths. As the conveying process proceeds, the remaining length of a section of pipe gradually decreases, and the small spacing between adjacent conveying rollers 21 can keep the short pipe continuing to move along the feeding direction.
[0030] like Figure 2 As shown, the limiting assembly 3 in the present invention includes a fixed plate 31 fixedly installed relative to the feeding frame 1 and a movable plate 32 movably installed relative to the feeding frame 1, the fixed plate 31 includes a first support member 311 and a first clamping plate 312 fixed to the upper end of the support member, the first clamping plate 312 is vertically arranged relative to the conveying roller 21, the movable plate 32 includes a second support member 321 and a second clamping plate 322 that can adjust the distance between the first support member 311, the second clamping plate 322 and the first clamping plate 312 They are arranged parallel to each other, and the bottoms of the first clamping plate 312 and the second clamping plate 322 are higher than the top of the conveying roller 21. When the pipe is transported on the conveying roller 21, the first clamping plate 312 and the second clamping plate 322 are located on both sides of the pipe, and the second clamping plate 322 on the movable plate 32 moves toward the direction close to the fixed plate 31, pushing the pipe to move in the same direction. When the other side of the pipe contacts the first clamping plate 312 of the fixed plate 31, it means that the limiting is completed, so that it can adapt to the limited transportation of pipes of different diameters and has strong practicality.
[0031] The cam 32 is fixed to the workbench 31 so that the cam 32 can be fixed to the workbench 310 to move the cam 320 upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam 320 can move upwards and downwards so that the cam
[0032] In the embodiment of the present invention, the assembly structure of the conveying assembly 2 and the limiting assembly 3 on the feeding frame 1 is specifically as follows: the feeding frame 1 is provided with a mounting seat 11 for mounting the conveying roller 21 and an adjusting rod 12 for mounting the movable plate 32 (such as Figure 1 and Figure 2As shown in the figure, the first support member 311 of the fixed plate 31 is fixedly mounted on one side of the mounting base 11, the bottom of the first support member 311 is close to one end of the conveying roller 21, and the second support member 321 is fixedly mounted on the adjusting rod 12. The lateral movement of the adjusting rod 12 drives the movable plate 32 as a whole to move toward or away from the fixed plate 31, so that the limiting component 3 can cooperate with the conveying component 2 to reliably move the pipe along the feeding direction.
[0033] like Figure 3 and Figure 4 As shown, the clamping and feeding assembly 4 in the embodiment of the present invention includes a lower clamping roller 41 fixed to the end of the feeding frame 1, an upper clamping roller 42 installed just above the lower clamping roller 41, a suspension seat 43 for installing the upper clamping roller 42, a bracket 44 for supporting the installation height of the upper clamping roller 42 and a first lifting cylinder 45 for adjusting the lifting height of the upper clamping roller 42 relative to the lower clamping roller 41. The first lifting cylinder 45 is fixedly mounted on the top of the bracket 44, and the output end of the first lifting cylinder 45 passes through the top of the bracket 44 and downwardly connects to the top of the suspension seat 43. The upper clamping roller 42 is movably mounted on the suspension seat 43, and a clamping roller driving motor 46 is provided on one side of the lower clamping roller 41. When it is not working, the upper clamping roller 42 is driven by the first lifting cylinder 45 to be suspended at the highest point and remain motionless. When the front end of the pipe moves to the clamping position When the feeding component 4 is in the position and is sensed by the second sensor, the first lifting cylinder 45 drives the upper clamping roller 42 to move downward until the upper clamping roller 42 contacts the pipe and cooperates with the lower clamping roller 41 to clamp the pipe, and then the clamping roller drive motor 46 starts to rotate forward, driving the lower clamping roller 41 to rotate to convey the pipe to continue to move along the feeding direction. When the clamping roller drive motor 46 starts working, the conveying motor 22 that drives the conveying roller 21 can stop working, and the conveying roller 21 can rotate as the pipe is clamped and conveyed forward. By setting the clamping component 4, the motor consumption of multiple conveying rollers 21 when working can be saved, and the reverse rotation of the clamping roller drive motor 46 can drive the pipe to move along the material withdrawal direction, and the corresponding operations are performed in conjunction with the sensing results of the first sensor and the second sensor, which is conducive to production automation and reduces production costs.
[0034] The feeding frame 1 in the embodiment of the present invention is provided with a "well"-shaped mounting frame 51 for mounting the chain-type collecting assembly 5, and the two long sides 511 of the "well"-shaped mounting frame 51 extending along the feeding direction are respectively located on both sides of the feeding frame 1, and the chain-type collecting assembly 5 is horizontally mounted on the two long sides 511, that is, the tail material collection direction driven by the rotation of the chain in the chain-type collecting assembly 5 is perpendicular to the long sides 511, and the two short sides (not shown in the figure) in the middle of the "well"-shaped mounting frame 51 are both located below the feeding frame 1, and the Two second lifting cylinders 52 are fixedly installed under the feeding frame 1. The output end of the second lifting cylinder 52 is fixedly connected to the short side of the "well"-shaped mounting frame 51. When the chain-type collecting assembly 5 needs to be lifted or lowered, the two second lifting cylinders 52 work simultaneously in the same direction to drive the short side of the output end to keep rising and falling synchronously. Since the short side is part of the overall structure of the "well"-shaped mounting frame 51, the "well"-shaped mounting frame 51 will also be driven to rise and fall, and then the chain-type collecting assembly 5 installed on the long side 511 will also rise and fall synchronously.
[0035] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application fall within the scope of the technical solution of the present application.
