Technical Field

[0001] The invention belongs to the technical field of automobile parts production, in particular to a device for cutting automobile interior plastic extrusion pipes. Background Art

[0002] Plastic pipes used in automobiles are generally used in the vehicle's liquid delivery systems, such as cooling systems, fuel systems, lubrication systems, etc.

[0003] At present, the production of automobile interior plastic pipes mostly relies on the basic molding of extruders. After the extruder extrude the plastic pipe, it is necessary to use a cutting mechanism to cut the longer plastic pipe into several equal-length pipe sections. When the existing cutting mechanism cuts the extruded plastic pipe, it is necessary to use a measuring tool such as a measuring ruler to measure the pipe in advance, and then cut the measured pipe. This cutting method is relatively traditional. On the one hand, it is time-consuming and labor-intensive, resulting in relatively low cutting efficiency. On the other hand, since the extruder extrude the plastic pipe continuously and uninterruptedly, the extruded plastic pipe is always in a moving state, which will bring inconvenience to the accurate measurement of the pipe, resulting in the length of the pipe section after cutting is not accurate enough, resulting in poor cutting effect.

DETAILED DESCRIPTION

[0014] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0015] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0016] See also Figure 1 as well as Figure 2 The present embodiment provides a cutting device for automobile interior plastic extrusion pipes, comprising a support platform 10, an extruder 20, a sliding support assembly 30, a cutting assembly 40, a resetting assembly 50 and a driving assembly 60. The extruder 20 is fixedly arranged at one end of the upper part of the support platform 10, and the sliding support assembly 30 is slidably arranged on the upper part of the support platform 10 and is located at the discharge end of the extruder 20. When the extruder 20 extrude the automobile interior plastic pipe, the plastic pipe pushes the sliding support assembly 30 to slide along the upper part of the support platform 10, and the cutting assembly 40 is reset. The cutting assembly 40 is arranged on the inner side of the sliding support assembly 30, and the driving assembly 60 is installed on the edge of the support platform 10. When the sliding support assembly 30 slides a predetermined distance along the upper part of the support platform 10, the driving assembly 60 is used to drive the cutting assembly 40 to move upward along the inner side of the sliding support assembly 30 to cut the plastic pipe. The resetting assembly 50 is arranged at the other end of the upper part of the support platform 10. When the cutting assembly 40 cuts the plastic pipe, the resetting assembly 50 is used to drive the sliding support assembly 30 to slide in the opposite direction.

[0017] After the extruder 20 extrude the automobile interior plastic pipe, the plastic pipe acts on the sliding support assembly 30, thereby driving the sliding support assembly 30 to slide along the upper part of the support platform 10, thereby driving the cutting assembly 40 to move synchronously with the plastic pipe. After the sliding support assembly 30 slides a predetermined distance, the driving assembly 60 drives the cutting assembly 40 to move upward along the inner side of the sliding support assembly 30, thereby performing a cutting process on the plastic pipe that is always in a moving state. After the cutting is completed once, the reset assembly 50 drives the sliding support assembly 30 to slide in the opposite direction along the upper part of the support platform 10, thereby driving the cutting assembly 40 to move synchronously with the plastic pipe. The cutting assembly 40 moves in the opposite direction to achieve the resetting of the cutting assembly 40 until the subsequent extruded plastic pipe acts on the sliding support assembly 30 again, and the sliding support assembly 30 slides along the upper part of the support platform 10 again to drive the cutting assembly 40 to move synchronously with the plastic pipe again. When the sliding support assembly 30 slides a predetermined distance again, the driving assembly 60 drives the cutting assembly 40 to move upward along the inner side of the sliding support assembly 30 again to achieve the re-cutting of the plastic pipe. This reciprocating cycle can continuously and automatically cut the plastic pipe extruded by the extruder 20 into a plurality of pipe sections of equal length.

[0018] See also Figure 1In one embodiment, a first guide rail 102 is fixedly provided on the upper portion of the support platform 10, and the sliding support assembly 30 includes a first support plate 301, a slide plate 302 and a second support plate 303. The slide plate 302 is slidably matched with the first guide rail 102, and the first support plate 301 and the second support plate 303 are respectively fixedly provided at both ends of the upper portion of the slide plate 302. A through hole (not shown in the figure) is provided on the first support plate 301 for the plastic pipe to pass through, and the cutting assembly 40 is slidably provided on the side of the first support plate 301 facing the second support plate 303.

[0019] After the extruder 20 extrude the automobile interior plastic pipe, the plastic pipe can pass through the first support plate 301 through the through hole on the first support plate 301 and abut against one side of the second support plate 303. As the extruder 20 continues to extrude the plastic pipe, the plastic pipe can push the second support plate 303 and then drive the slide plate 302 to slide along the first guide rail 102. The slide plate 302 drives the first support plate 301 and the cutting assembly 40 to move synchronously with the plastic pipe. When the first support plate 301, the second support plate 303 and the cutting assembly 40 move a predetermined distance, the driving assembly 60 drives the cutting assembly 40 to move upward along one side of the first support plate 301, thereby cutting the plastic pipe.

[0020] See also Figure 1 as well as Figure 2 In one embodiment, a second guide rail 304 distributed vertically is fixedly provided on one side of the first support plate 301 facing the second support plate 303, and the cutting assembly 40 includes a support base 401, a cutting box 403, a chain saw 404 and a cutting motor 405. A guide rail groove (not shown in the figure) matching with the second guide rail 304 is opened on one side of the support base 401, and the cutting box 403 is provided with two groups. The two groups of cutting boxes 403 are fixedly installed at both ends of the upper part of the support base 401, and sprockets (not shown in the figure) are rotatably provided inside the two groups of cutting boxes 403. The chain saw 404 is sleeved between the two groups of sprockets, and the cutting motor 405 is fixedly installed on the side wall of one group of the cutting boxes 403, and is used to drive the sprocket inside the group of the cutting boxes 403 to rotate.

[0021] The corresponding sprocket is driven to rotate by the cutting motor 405, thereby driving the chain saw 404 to rotate. When the extruded plastic pipe pushes the first support plate 301 and the second support plate 303 to move the first support plate 301 and the second support plate 303 a predetermined distance, the second drive assembly 60 drives the support base 401 to slide upward along the side wall of the first support plate 301, thereby driving the cutting motor 405 and the rotating chain saw 404 to move upward. When the rotating chain saw 404 moves upward, it acts on the plastic pipe, thereby cutting the plastic pipe.

[0022] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 In one embodiment, an extension push rod 402 is fixedly provided on the side wall of the support base 401, and the driving assembly 60 includes a first support rod 601, an inclined plate 602 and a second support rod 603. The first support rod 601 and the second support rod 603 are both fixedly provided on the upper edge of the support platform 10. A support shaft 606 is fixedly provided on the side wall of the first support rod 601, and a limiting rod 604 is fixedly provided on the side wall of the second support rod 603. A sleeve 605 is fixedly provided at one end of the bottom of the inclined plate 602, and the other end is overlapped on the limiting rod 604. The sleeve 605 is rotatably sleeved on the outside of the support shaft 606.

[0023] When the extruded plastic pipe pushes the first support plate 301 and the second support plate 303 to move a predetermined distance, the extended push rod 402 on the side wall of the support base 401 acts on the upper surface of the inclined plate 602 and slides down along the upper surface of the inclined plate 602. The inclined plate 602 pushes the extended push rod 402 and then drives the support base 401 to slide up along the side wall of the first support plate 301. When the support base 401 slides up, it drives the chain saw 404 and the cutting motor 405 to move up as a whole. The cutting motor 405 drives the chain saw 404 to rotate. The rotating chain saw 404 acts on the plastic pipe and then cuts the plastic pipe. The pipe section formed after the plastic pipe is cut falls off by itself.

[0024] See also Figure 2 In one embodiment, the bottom of the support base 401 is also connected to the slide plate 302 via a first elastic member 406 , and the first elastic member 406 is used to provide elastic pulling force to the support base 401 .

[0025] When the extension push rod 402 slides up along the upper surface of the inclined plate 602, the support base 401 slides up along the side wall of the first support plate 301, and the first elastic member 406 is stretched. When the chain saw 404 finishes cutting the plastic pipe, the extension push rod 402 slides away from the upper end of the inclined plate 602, and then the first elastic member 406 pulls the support base 401 so that the support base 401 slides down along the side wall of the first support plate 301, thereby driving the chain saw 404 and the cutting motor 405 to move downward, thereby resetting the chain saw 404.

[0026] See also Figure 1In one embodiment, the reset assembly 50 includes a second elastic member 501 and a bracket plate 502. The bracket plate 502 is fixedly arranged on the upper part of the support platform 10 at one end away from the extruder 20. One end of the second elastic member 501 is connected to the bracket plate 502, and the other end is connected to the second support plate 303, so as to provide elastic support for the second support plate 303.

[0027] When the extruder 20 extrude the automobile interior plastic pipe, the plastic pipe pushes the second support plate 303 so that the second support plate 303 and the first support plate 301 move as a whole, and the second elastic member 501 is compressed by force. When the chain saw 404 finishes cutting the plastic pipe and the first elastic member 406 pulls the support base 401 to move the chain saw 404 downward, the chain saw 404 will generate a certain downward pulling force on the cut pipe section, and the pipe section can fall quickly under the action of the downward pulling force, and then separate from the subsequently extruded plastic pipe. Then the second elastic member 501 pushes the second support plate 303, thereby driving the second support plate 303, the slide plate 302 and the first support plate 301 to move in the opposite direction, until the end of the subsequently extruded plastic pipe abuts against the side wall of the second support plate 303 again, and the plastic pipe pushes the second support plate 303 again so that the second support plate 303, the slide plate 302 and the first support plate 301 move again, and then the inclined plate 602 moves again. The extension push rod 402 is pushed, thereby driving the support base 401, the chain saw 404 and the cutting motor 405 to move upward again to cut off the subsequent plastic pipe again; in the above-mentioned process in which the second elastic member 501 pushes the second support plate 303 and then drives the second support plate 303, the slide plate 302 and the first support plate 301 to move in the opposite direction, the support base 401, the chain saw 404 and the cutting motor 405 move in the opposite direction synchronously, and when the support base 401 moves in the opposite direction, the extension push rod 402 on its side wall acts on the lower surface of the inclined plate 602, thereby pushing the inclined plate 602 so that the inclined plate 602 drives the sleeve 605 to rotate relative to the support shaft 606, and the inclined plate 602 is separated from the limit rod 604 when rotating, until the extension push rod 402 slides off the lower end of the inclined plate 602, and the inclined plate 602 relies on gravity to drive the sleeve 605 to rotate in the opposite direction relative to the support shaft 606, and the inclined plate 602 is re-connected to the upper part of the limit rod 604 to achieve the reset of the inclined plate 602.

[0028] In one embodiment, the first elastic member 406 and the second elastic member 501 may be springs or metal springs, which are not limited here.

[0029] See also Figure 1 In one embodiment, a support leg 101 is fixedly provided at the bottom of the support platform 10 .

[0030] In the embodiment of the present invention, after the extruder 20 extrude the automobile interior plastic pipe, the plastic pipe acts on the sliding support assembly 30, thereby driving the sliding support assembly 30 to slide along the upper part of the support platform 10, thereby driving the cutting assembly 40 to move synchronously with the plastic pipe. After the sliding support assembly 30 slides a predetermined distance, the driving assembly 60 drives the cutting assembly 40 to move upward along the inner side of the sliding support assembly 30, thereby performing a cutting process on the plastic pipe that is always in a moving state. After the cutting is completed once, the resetting assembly 50 drives the sliding support assembly 30 to slide in the opposite direction along the upper part of the support platform 10, thereby driving the cutting assembly 40 to move in the opposite direction, realizing the resetting of the cutting assembly 40, until the rear When the continuously extruded plastic pipe acts on the sliding support assembly 30 again, the sliding support assembly 30 slides along the upper part of the support platform 10 again to drive the cutting assembly 40 to move synchronously with the plastic pipe again. After the sliding support assembly 30 slides a predetermined distance again, the driving assembly 60 drives the cutting assembly 40 to move upward along the inner side of the sliding support assembly 30 again to cut the plastic pipe again. In this reciprocating cycle, the plastic pipe extruded by the extruder 20 can be continuously and automatically cut into a plurality of equal-length pipe sections. Compared with the prior art, the plastic pipe extruded by the extruder 20 can be continuously and automatically cut into equal-length sections, which has the advantages of good plastic pipe cutting effect and high cutting efficiency.

Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
