Detailed Embodiment

[0024] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0025] This technical solution provides a pipe feeding mechanism for an automatic pipe shrinking machine, which includes a feeding box 11 and a feeding seat 12. The feeding seat 12 is installed inside the feeding box 11, and the feeding seat 12 can move up and down obliquely relative to the feeding box 11;

[0026] The top of the feeding box 11 includes a storage part 111 and a stepped feeding part 112 arranged in sequence along the feeding direction of the pipe. The surface of the storage part 111 slopes downward along the feeding direction of the pipe. The stepped feeding part 112 includes at least three inclined feeding plates, and the three feeding plates are parallel to each other. The top heights of the three feeding plates increase in sequence along the feeding direction of the pipe. The extending direction of the feeding plate is perpendicular to the inclined direction of the surface of the storage part 111. There is a feeding gap between the storage part 111 and the feeding plate and between adjacent two feeding plates.

[0027] The feeding seat 12 includes at least three inclined ejector plates 120, and the three ejector plates 120 are parallel to each other. The top heights of the three ejector plates 120 increase in sequence along the feeding direction of the pipe. The ejector plates 120 are parallel to the feeding plates, and one ejector plate 120 is movably accommodated in one feeding gap.

[0028] In the prior art, the feeding machine for pipes generally requires technicians to feed one by one, so it will waste a certain amount of labor cost and consume a certain amount of feeding time. Therefore, in order to realize the effective feeding of pipes in an automatic pipe shrinking machine and reduce human participation as much as possible, this technical solution also proposes a feeding mechanism for an automatic pipe shrinking machine, as Figures 1-5 shown, which includes a feeding box 11 and a feeding seat 12 that can move up and down obliquely relative to the feeding box 11.

[0029] Specifically, the top of the feeding box 11 in this solution includes a storage part 111 and a stepped feeding part 112 arranged in sequence along the feeding direction of the pipe (not shown in the figure). Among them, the storage part 111 is used for technicians to stack-feed the feeding mechanism, and the stepped feeding part 112 is used to realize the one-by-one feeding of the stacked pipes. It should be noted that the stepped feeding part 112 can be connected to an existing conveyor chain / conveyor belt (not shown in the figure) to convey the pipes one by one to the next process of the pipe shrinking step.

[0030] The following takes a feeding mechanism in which the stepped feeding part 112 includes three inclined feeding plates and the feeding seat 12 includes three inclined ejector plates 120 to illustrate the pipe feeding process. The feeding plate closest to the storage part 111 is named the first feeding plate, the feeding plate farthest from the storage part 111 is named the third feeding plate, and at the same time, the ejector plate 120 closest to the storage part 111 is named the first ejector plate, and the ejector plate 120 farthest from the storage part 111 is named the third ejector plate.

[0031] In one embodiment, the feeding process of the feeding mechanism is realized according to the following steps: First, the standby state of the feeding mechanism is as Figure 4 the state (a1) and Figure 5As shown in the state (b1), the technician stacks the piled-up pipes in the storage section 111. Meanwhile, under the action of the inclined surface of the storage section 111, the pipes roll and accumulate on the top of the first pusher plate. Then, the first pusher plate moves obliquely upward along the feeding gap. As Figure 4 the state (a2) and Figure 5 the state (b2) shown, when the pipes located on the top of the first pusher plate move upward, they roll successively towards the tops of the first feeding plate and the second pusher plate under the action of gravity. Then, the second pusher plate moves obliquely upward along the feeding gap, so that the pipes located on the top of the second pusher plate roll successively towards the tops of the second feeding plate and the third pusher plate under the action of gravity during the upward movement. Finally, the third pusher plate moves obliquely upward along the feeding gap, so that the pipes located on the top of the third pusher plate roll towards the top of the third feeding plate under the action of gravity during the upward movement, thus realizing the step-by-step feeding of the pipes.

[0032] Furthermore, the upper surfaces of the feeding plate and the pusher plate 120 are both inclined downward along the pipe discharging direction, and the inclination angle of the upper surface of the feeding plate is the same as that of the upper surface of the pusher plate 120.

[0033] In a preferred embodiment of the present technical solution, the upper surfaces of the feeding plate and the pusher plate 120 are both inclined downward along the pipe discharging direction, making it easier for the pipes to roll to the next step during the step-by-step feeding process, which is beneficial to ensuring the realization of the step-by-step feeding of the pipes.

[0034] Furthermore, the feeding seat 12 further includes a pusher connecting plate 121, a feeding driver 122 and a feeding transmission block 123. The pusher connecting plate 121 is connected to the end of the pusher plate 120, and all the pusher plates 120 are connected through the pusher connecting plate 121. The feeding driver 122 is arranged inside the feeding box 11. The bottom of the feeding transmission block 123 is connected to the output end of the feeding driver 122, and the side wall of the feeding transmission block 123 is connected to the pusher plate 120. The feeding driver 122 is used to drive all the pusher plates 120 to move in the feeding gap through the feeding transmission block 123 simultaneously.

[0035] In another preferred embodiment of the present technical solution, the setting of the pusher connecting plate 121 enables multiple pusher plates 120 to move simultaneously. In this way, on the premise of ensuring the step-by-step feeding of the pipes, the efficiency of the step-by-step feeding of the pipes can be improved, and the equipment cost can be saved at the same time.

[0036] Further explanation, the loading seat 12 further includes at least two guide rods 124. The guide rods 124 are arranged inside the loading box 11, and the two guide rods 124 are respectively located on both sides of the loading driver 122. The extending direction of the guide rods 124 is parallel to the moving direction of the ejector plate 120. The top ends of the guide rods 124 pass through the loading transmission block 123, and the loading transmission block 123 moves along the extending direction of the guide rods 124.

[0037] In addition, the loading seat 12 of this solution is also provided with at least two guide rods 124 to ensure the moving stability of the loading seat 12 and ensure the effective progress of the step-by-step loading of the pipes.

[0038] Further explanation, it further includes a sliding component 13. The sliding component 13 abuts between the loading box 11 and the loading seat 12.

[0039] The sliding component 13 includes a slide rail 131 and a slider 132, and the slider 132 is slidably installed on the slide rail 131. The slide rail 131 protrudes from both sides inside the loading box 11, and the extending direction of the slide rail 131 is parallel to the moving direction of the ejector plate 120. The slider 132 protrudes from both sides outside the ejector connecting plate 121, and a chute for accommodating the slide rail 131 is provided on the outer wall of the slider 132.

[0040] Furthermore, a sliding component 13 is additionally provided in the loading mechanism of this solution. Through the cooperation of the slide rail 131 and the slider 132, it is more beneficial to ensure the moving stability of the loading seat 12 and ensure the effective progress of the step-by-step loading of the pipes.

[0041] Further explanation, it further includes a separating component 14. The separating component 14 is erected on the top of the loading box 11, and the separating component 14 is located above the storage part 111.

[0042] The separating component 14 includes auxiliary rods 141 and at least one separating plate 142. The auxiliary rods 141 are erected on the top of the loading box 11, the separating plate is detachably installed on the auxiliary rods 141, and the separating plate 142 is used to divide the surface of the storage part 111 into multiple storage areas.

[0043] In addition, this solution also provides a separating component 14 above the storage part 111 for dividing the surface of the storage part 111 into multiple storage areas. On the one hand, it can make the stacked pipes be loaded step by step neatly, and on the other hand, it also enables the loading mechanism to load at least two pipes step by step to further improve the loading efficiency of the loading mechanism.
