Description

Technical Field

[0001] The present invention relates to the technical field of PVC pipe processing auxiliary equipment, and particularly relates to a short-distance auxiliary moving device based on PVC pipe processing. Background Art

[0002] PVC is a synthetic material that is deeply loved, quite popular, and widely used in the world today. The main component of PVC pipe is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is back-coated adhesive. During the production process of PVC pipes, due to the long length of the pipe body, it is necessary to support the pipe body during production. Currently, during pipe body production, the pipe body is supported by a workbench, and then manually or by an external moving device to assist its slow movement for auxiliary discharging. However, the newly produced PVC pipes are relatively soft, and their surfaces are easily scratched during the movement process, and the pipe bodies are easily deformed due to extrusion.

[0003] However, in terms of the discharging method of the current traditional PVC pipe production line, after the PVC pipes are produced, they are slowly discharged outwards through the discharging port of the PVC pipe production line. The discharging position supports the pipe body of the PVC pipe through a cooling support table or a conveyor belt. When discharging, the pipe body slowly moves outwards, and friction is likely to occur between the surface of the pipe body and the support table or the conveyor belt, which is likely to cause wear to the surface of the pipe body.

[0010] Optionally, a clamping plate guiding column is fixedly connected to the surface of the reset support plate. A positioning clamping block is slidably connected to the clamping plate guiding column. A tightening spring is fixedly connected to the surface of the reset support plate.

[0012] Optionally, two groups of frame end guide rods are respectively rotatably connected to both ends of the circulating conveyor frame. Two outer end pulleys are rotatably connected to the frame end guide rods. The outer end pulleys are in rolling connection with the circulating guide frame.

A conical discharging end expansion cone end is provided at the upper end of the discharging end unit adjusting arc frame. The cone end of the discharging end expansion cone end faces left.

[0015] Beneficial effects The discharging mechanism of the PVC pipe production line according to the embodiments of the present invention has been improved. Compared with the traditional PVC pipe production line, it has an auxiliary propulsion and support effect on the PVC pipe body, realizes the continuous pushing and pulling and positioning effect of the PVC pipe body. Through the movement linkage of the auxiliary support propulsion mechanism, the clamping and positioning mechanism is driven to realize the effects of fixed-point clamping and fixed-point loosening of the pipe body, and the pipe body is assisted in positioning to realize the function of cyclic conveying.

[0016] In addition, through the action of the traction drive assembly, the synchronous linkage shaft is driven by the propulsion drive member. The propulsion drive member drives the synchronous linkage shaft to rotate clockwise. When a chain drive is formed between the two groups of synchronous linkage shafts, the two synchronous drag chains rotate clockwise. Since the synchronous drag chain is fixedly connected to the drag positioning end column of the cyclic conveying frame, the cyclic conveying frame can be pulled through the movement of the synchronous drag chain, realizing the effect of uniformly cyclic propulsion of the cyclic conveying frame. The two ends of the cyclic conveying frame are in rolling connection with the cyclic guide frame, playing a guiding role in the uniform cyclic movement of the cyclic conveying frame, so as to keep the reset support plate and the positioning clamp block of the cyclic conveying frame always facing outward, which is beneficial to clamping and positioning the PVC pipe body.

[0017] In addition, through the cooperation of the feed end adjusting beam and the cyclic conveying frame, when a cyclic conveying frame moves uniformly and cyclically on the cyclic guide frame, when the cyclic conveying frame moves to the left side below the cyclic guide frame, in the normal state, under the action of the top spring, the positioning clamp block is in a clamped state. When the cyclic conveying frame moves to the position of the feed end adjusting beam, the clamp adjusting wheel forms a rolling connection with the outer conical surface of the feed end expansion cone end. Through the action of the conical surface, the positioning clamp block is pushed outward, increasing the distance between the two positioning clamp blocks. During the process of the cyclic conveying frame winding from the left end of the cyclic guide frame to the upper surface of the cyclic guide frame, the two positioning clamp blocks always remain separated, so that the two positioning clamp blocks move to both sides of the PVC pipe body. Then the cyclic conveying frame continues to move to the right, so that the clamp adjusting wheel disengages from the feed end adjusting beam, and the PVC pipe body is clamped from both sides under the action of the top spring, realizing the positioning function of the PVC pipe body. The PVC is assisted in positioning when moving on the auxiliary moving assembly, improving the stability of the auxiliary movement.

[0018] In addition, through the cooperation of the discharge end adjusting frame and the positioning clamping block, when the circulating conveying frame for positioning and supporting the PVC pipe body runs to the right side of the upper surface of the circulating guide frame, the clamping block adjusting wheel of the positioning clamping block forms a rolling connection with the outer conical surface of the expansion cone end of the discharge end, and expands the distance between the two positioning clamping blocks clamping the PVC pipe body, so that the PVC pipe body is disengaged from the clamping of the two positioning clamping blocks. Then, this group of circulating conveying frames rotates downward from the right end of the circulating guide frame under the pulling of the traction drive assembly, facilitating the next cycle. Through the circulating operation of the circulating conveying frame, the PVC pipe bodies in the discharge can be continuously conveyed, and through the cooperation of the conveying mechanism and the positioning mechanism, the functions of fixed-point clamping and fixed-point disengagement of the PVC pipe bodies are realized, thereby realizing the circulating positioning and conveying of the PVC pipe bodies.

Unless otherwise specified, the terms used herein have the ordinary meanings in the art. The same reference numerals in the drawings represent the same components

[0024] Embodiment: Please refer to Figures 1 to 11 : The present invention provides a short-distance auxiliary moving device for PVC pipe processing, including: an outer support frame 1; a circulating guide frame 2 is respectively fixedly connected to the inner sides of the outer peripheries of the two plates of the outer support frame 1; a traction driving assembly is installed on the outer support frame 1; a circulating conveyor frame 4 is movably connected to the circulating guide frame 2, the traction driving assembly is connected to and drives the circulating conveyor frame 4, four reset support plates 401 are fixedly connected to the upper surface of the circulating conveyor frame 4, and six groups of guide square grooves 402 are formed on the frame of the circulating conveyor frame 4, each group of guide square grooves 402 has two rectangular through grooves, a dragging positioning end column 404 is respectively fixedly connected to both ends of the circulating conveyor frame 4, and the end of the dragging positioning end column 404 is fixedly connected to the traction driving assembly; a feed end adjusting beam 5 is located on the left inner side of the outer support frame 1, and both ends of the feed end adjusting beam 5 are respectively fixedly connected to the inner surfaces of the two plates of the outer support frame 1; a discharge end adjusting frame 6 is located on the right inner side of the outer support frame 1, and both ends of the discharge end adjusting frame 6 are respectively fixedly connected to the inner surfaces of the two plates of the outer support frame 1

[0025] In addition, according to an embodiment of the present invention, as Figure 4As shown in the figure, a support connecting plate 101 is fixedly connected to the outer periphery of the outer support frame body 1. The end of the support connecting plate 101 is fixedly connected to the circulating guide frame 2. Support feet 102 are fixedly connected to the outer surfaces of the two plates of the outer support frame body 1. The support connecting plate 101 plays a role in fixing the circulating guide frame 2, and the outer support frame body 1 is supported by the support feet 102. The two side frames of the outer support frame body 1 are fixedly connected by an inlet end adjusting beam 5 and an outlet end adjusting frame 6.

[0026] In addition, according to an embodiment of the present invention, as Figure 3 shown, the traction drive assembly includes two synchronous linkage shafts 3 and one propulsion drive member 7. The two synchronous linkage shafts 3 are respectively rotatably connected to the left and right ends of the two plates of the outer support frame body 1 through bearings. The propulsion drive member 7 is fixedly connected to the left rear side of the outer support frame body 1, and the propulsion drive member 7 is connected to and drives the synchronous linkage shaft 3 at the left end. Two synchronous drag sprockets 301 are respectively fixedly connected to the two synchronous linkage shafts 3. The two synchronous linkage shafts 3 are connected and form a chain drive through two groups of synchronous drag sprockets 301 and two synchronous drag chains 302. The synchronous drag sprocket 301 is fixedly connected to the drag positioning end post 404. Through the action of the traction drive assembly, the synchronous linkage shaft 3 is driven by the propulsion drive member 7. The propulsion drive member 7 drives the synchronous linkage shaft 3 to rotate clockwise. When a chain drive is formed between the two synchronous linkage shafts 3, the two synchronous drag chains 302 rotate clockwise. Since the synchronous drag chain 302 is fixedly connected to the drag positioning end post 404 of the circulating conveyor frame 4, the circulating conveyor frame 4 can be pulled through the movement of the synchronous drag chain 302, achieving the effect of uniformly circulating and advancing the circulating conveyor frame 4.

[0027] In addition, according to an embodiment of the present invention, as Figure 8 shown, a clamping plate guide post 4011 is fixedly connected to the surface of the reset support plate 401. A positioning clamp block 403 is slidably connected to the clamping plate guide post 4011. A tightening spring 4012 is fixedly connected to the surface of the reset support plate 401. The tightening springs 4012 are located on both sides of the reset support plate 401. The other end of the tightening spring 4012 is fixedly connected to the outer surface of the positioning clamp block 403. The clamping plate guide post 4011 is slidably connected to the clamp block guide hole 4031, playing a guiding role for the positioning clamp block 403. The tightening spring 4012 pushes the positioning clamp block 403, and the positioning and clamping effect of the PVC pipe body is achieved through the two positioning clamp blocks 403.

[0028] In addition, according to an embodiment of the present invention, as Figure 8As shown, a clamping block guiding hole 4031 is formed on the outer surface of the positioning clamping block 403, and two clamping block supporting feet 4032 are provided below the positioning clamping block 403. The lower end of the clamping block supporting foot 4032 is fixedly connected with a clamping block adjusting wheel 4033. The positioning clamping block 403 is slidably connected to the circulating conveying rack 4, and the clamping block supporting foot 4032 is slidably connected to the guiding square groove 402. Under normal conditions, the positioning clamping block 403 is pushed towards the middle under the pushing action of the pressing spring 4012, and the distance between the two positioning clamping blocks 403 is adjusted by the rolling connection between the clamping block adjusting wheel 4033 and the feeding end adjusting beam 5 and the discharging end adjusting frame 6.

[0029] In addition, according to an embodiment of the present invention, as Figure 7 shown, two groups of frame end guide rods 405 are respectively rotatably connected to both ends of the circulating conveying rack 4, and two outer end pulleys 4051 are rotatably connected to the frame end guide rods 405. The outer end pulleys 4051 are in rolling connection with the circulating guide frame 2. The outer end pulleys 4051 play a role in guiding the circulating conveying rack 4 and keep the outer surface of the circulating conveying rack 4 always facing the outside of the auxiliary conveying device.

[0030] In addition, according to an embodiment of the present invention, as Figure 6 shown, three feeding end unit adjusting arc frames 501 are fixedly connected to the feeding end adjusting beam 5. The feeding end unit adjusting arc frame 501 is an arc-shaped frame body. The feeding end unit adjusting arc frame 501 is coaxial with the left arc-shaped frame of the circulating guide frame 2. A conical feeding end expanding cone end 5011 is provided at the lower end of the feeding end unit adjusting arc frame 501. The cone end of the feeding end expanding cone end 5011 faces right. Through the action of the feeding end adjusting beam 5, when the circulating conveying rack 4 moves to the left below the circulating guide frame 2 and reaches the position of the feeding end adjusting beam 5, the clamping block adjusting wheel 4033 forms a rolling connection with the outer conical surface of the feeding end expanding cone end 5011. Through the action of the conical surface, the positioning clamping block 403 is pushed outwards, increasing the distance between the two positioning clamping blocks 403, keeping the two positioning clamping blocks 403 always in a separated state, moving the two positioning clamping blocks 403 to both sides of the PVC pipe body. Then the circulating conveying rack 4 continues to move to the right, causing the clamping block adjusting wheel 4033 to disengage from the feeding end adjusting beam 5, and clamping the PVC pipe body from both sides under the action of the pressing spring 4012, realizing the positioning function of the PVC pipe body and the function of fixed-point clamping.

[0031] In addition, according to an embodiment of the present invention, as Figure 5As shown in the figure, three discharge end unit adjustment arc frames 601 are fixedly connected to the discharge end adjustment frame 6. The discharge end unit adjustment arc frame 601 is an arc-shaped frame body. The discharge end unit adjustment arc frame 601 is coaxial with the arc-shaped frame on the right side of the circulation guide frame 2, and a discharge end expansion cone end 6011 with a conical structure is provided at the upper end of the discharge end unit adjustment arc frame 601. The cone end of the discharge end expansion cone end 6011 faces left. When the circulation conveyor frame 4 runs to the right side of the upper surface of the circulation guide frame 2, the clamping block adjusting wheel 4033 here forms a rolling connection with the outer conical surface of the discharge end expansion cone end 6011, expanding the distance between the two positioning clamping blocks 403 clamping the PVC pipe body, so that the PVC pipe body is disengaged from the clamping of the two positioning clamping blocks 403. Then, this group of circulation conveyor frames 4 rotates downward from the right end of the circulation guide frame 2 under the pulling of the traction drive assembly and moves leftward without load, thus participating in the next cycle, realizing the function of triggering the fixed-point loosening of the clamping assembly.

[0032] Specific usage method and function of this embodiment: In the present invention, first, this short-distance auxiliary moving device is arranged at the position of the PVC pipe body discharge port, so that the circulation conveyor frame 4 is flush with the PVC pipe body discharge port in height, and the outer end of the PVC pipe body is aligned with the positioning area of the two positioning clamping blocks 403. The propulsion drive member 7 drives the synchronous linkage shaft 3. The propulsion drive member 7 drives the synchronous linkage shaft 3 to rotate clockwise. When a chain drive is formed between the two synchronous linkage shafts 3, the two synchronous drag chains 302 rotate clockwise. Since the synchronous drag chain 302 is fixedly connected to the drag positioning end post 404 of the circulation conveyor frame 4, the circulation conveyor frame 4 can be pulled through the movement of the synchronous drag chain 302, realizing the effect of uniformly circulating and advancing the circulation conveyor frame 4, and controlling the moving speed of the circulation conveyor frame 4 to be equal to the discharge speed of the PVC pipe body through the propulsion drive member 7. On the left side of the auxiliary conveying device, the positioning clamping blocks 403 clamp the PVC pipe body through the action of the spring and convey it to the right. When the circulation conveyor frame 4 runs to the right side of the upper surface of the circulation guide frame 2, the clamping block adjusting wheel 4033 here forms a rolling connection with the outer conical surface of the discharge end expansion cone end 6011, expanding the distance between the two positioning clamping blocks 403 clamping the PVC pipe body, so that the PVC pipe body is disengaged from the clamping of the two positioning clamping blocks 403. Then, this group of circulation conveyor frames 4 rotates downward from the right end of the circulation guide frame 2 under the pulling of the traction drive assembly and moves leftward without load, thus participating in the next cycle. When this circulation conveyor frame 4 moves to the position of the feed end adjustment beam 5, the clamping block adjusting wheel 4033 and the positioning clamping block 403 are pushed outward through the action of the conical surface, increasing the distance between the two positioning clamping blocks 403. After the circulation conveyor frame 4 winds from the left end of the circulation guide frame 2 to the upper surface of the circulation guide frame 2, the clamping block adjusting wheel 4033 disengages from the feed end adjustment beam 5, and the two positioning clamping blocks 403 clamp the PVC pipe body again from both sides and convey it to the right, realizing the function of circulating transportation.

[0033] Finally, it should be noted that when describing the positions of various components and their cooperation relationships, etc., one / a pair of components are usually used as examples. However, those skilled in the art should understand that such positions, cooperation relationships, etc. are equally applicable to other components / other pairs of components.
