Description

[0002] PE is polyethylene. Generally, the application range of PE pipe water supply pipeline is below 40℃, and it cannot be used for hot water delivery pipeline. Pipes produced from polyethylene raw materials have excellent corrosion resistance, flexibility, low temperature resistance, fracture toughness, etc., and will not rust or scale. In the current context of "plastic replacing steel", PE pipes are widely used in pipeline production. Polyethylene can be divided into high-density polyethylene, medium-density polyethylene, low-density polyethylene, and linear low-density polyethylene according to density.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 1-10 The present invention is further described with examples:

[0044] A forming device for a high-strength antibacterial PE water supply pipe comprises a support frame 1, an upper end face of the support frame 1 is provided with an extrusion forming device 11, a forming port on the extrusion forming device 11 is directly opposite to a traction tube 12, and a vacuum device 13 is provided at one end of the traction tube 12; a cutting mechanism 2 is provided on one side of the support frame 1; a traction mechanism 3 and a wrapping mechanism 4 are provided on one side of the lower part of the support frame 1; an extrusion mechanism 5 is provided on the outer side of the traction tube 12; and a support leg on the support frame 1 is fixedly connected to a collection shell 61 via a fixing rod 6.

[0045] In this embodiment, the cutting mechanism 2 includes a fixed frame 21, a motor 22 is fixed on the upper part of the fixed frame 21, a rotating shaft 23 is connected to the output end of the motor 22, a transmission plate 24 is fixedly connected to one end of the rotating shaft 23, the transmission plate 24 is connected to a connecting plate 25 through a first transmission rod, the lower part of the connecting plate 25 is connected to a transmission frame 26 through a second transmission rod, scrapers 27 are fixedly connected to the lower parts of both sides of the transmission frame 26, a first blade is provided at the upper end of the scraper 27, and a second blade is provided at the lower end of the scraper 27, a first L-shaped plate 28 is fixedly connected to one side of the scraper 27, a sliding rod 29 is fixedly connected to one side of the upper end surface of the first L-shaped plate 28, the upper end of the sliding rod 29 passes through the interior of a limiting hole 222 opened on one side of a limiting block 221, and the upper end of one side of the limiting block 221 is fixedly connected to the bottom of the upper part of the fixed frame 21. The motor 22 on the cutting mechanism 2 is started, and the motor 22 drives the rotating shaft 23 to rotate clockwise. The rotating shaft 23 drives the transmission plate 24 clockwise. The transmission plate 24 is subjected to force transmitted to the connecting plate 25 through the first transmission rod, and the force is transmitted downward to the transmission frame 26 under the clockwise force, so that the transmission frame 26 and the scraper 27 move downward. When the transmission frame 26 moves downward, the sliding rod 29 slides downward in the limiting hole 222 by the transmission of the first L-shaped plate 28, which can effectively ensure that the transmission frame 26 and the scraper 27 move vertically downward. The second blade first scrapes off the material that is not completely preheated. After the transmission plate 24 rotates clockwise to 180 degrees, the transmission plate 24 starts to rotate upward clockwise, so that the transmission frame 26 and the scraper 27 move upward, so that the first blade on the scraper 27 scrapes off the material that is not completely preheated. The scraped material falls vertically downward on the inner bottom of the collecting shell 61. Through the setting of the scraper 27, the scraped material falls vertically downward, avoiding the scraped material from falling anywhere else at will. Moreover, one operation can scrape twice, effectively improving the removal efficiency.

The first hydraulic cylinder 31 is started to drive the first extension rod 33 to move to one side. The first extension rod 33 is forced to drive the moving block 33 to one side. The moving block 33 drives the telescopic rod 341, the traction plate 346, and the traction shell 348 to move to one side. Among them, the first guide rod 342 on the telescopic rod 341 moves to one side along the guide rail frame 343. At this time, the two traction shells 348 have been matched to form a trumpet shape. During the movement of the moving block 33, one end of the two traction shells 348 is inserted into the molding port on the extrusion forming device 11, and the movement stops. Figure 5 As shown, the extrusion forming device 11 is started again to extrude the material out of the water pipe, and the extruded water pipe is covered toward one end of the two traction shells 348. The length of the extruded water pipe is extended to allow the wrapping shell 4292 to wrap it. After the length of the extruded water pipe is extended for a certain distance, the shape of the two traction shells 348 allows the extruded water pipe to always maintain a tapered mouth, effectively preventing the traction tube from pulling the extruded water pipe, and allowing the port of the extruded water pipe to continue to remain in an open state, so that the port of the extruded water pipe can be smoothly covered on the outside of the traction tube to prevent it from detaching from one end of the traction tube, thereby improving work progress, work efficiency, and work performance.

The H-shaped plate 425 is rotatably matched with a first bearing rod 426 through a rotating hole 4251. Both ends of the first bearing rod 426 are fixedly connected to support frames 427. The first hydraulic cylinder 31 is started to move the moving block 33 to the other side, wherein the first extending rod 32 drives the resistance block 41 to move to one side. During the movement of the resistance block 41, the two side surfaces of the resistance block 41 will resist the resistance rod 421, and the resistance rod 421 gradually moves to one side along with the convex surface of the resistance block 41. After the resistance rod 421 is subjected to force, it is pressed to one side against the lower part of the H-type plate 425 through the first pressure plate 4211, wherein the second pressure plate 4212 is pressed to one side against the first spring body 422. At the same time, the second guide rod 423 is forced to slide to one side inside the first through hole 4241. When the H-type plate 425 is subjected to the resistance pressure from the lower part, it rotates clockwise on the outer side of the first bearing rod 426.

The upper part of the H-shaped plate 425 is pressed against the third pressing plate 428, and the third guide rod 4281 is forced to one side by the force transmitted by the third pressing plate 428, and the third guide rod 4281 slides horizontally to one side inside the second through hole 4242, and the pressure plate 4282 is squeezed on the second spring body 4283 by the power of the third guide rod 4281, and is gradually moved to the parcel rack 429 with the third pressing plate 428. The parcel rack 429 is forced to one side by the wrapping rod 4291 and the wrapping shell 4292, and at the same time, the two wrapping shells 4292 gradually cooperate with each other, wherein the two traction shells 348 also move to one side and pull the squeezed water pipe to move to one side, at this time, the two wrapping shells 4292 are completely wrapped on the outside of one end of the two traction shells 348, and the squeezing of the wrapping shells 4292 can effectively prevent the traction shells 348 from detaching during traction.

[0057] S4, first wrapping: start the first hydraulic cylinder 31 to drive the resistance block 41, so that the resistance rod 421 moves to one side, and then use the H-shaped plate 425 to convert the power to move the third guide rod 4281 to the other side, and drive the two wrapping shells 4292 to wrap the outside of the two traction shells 348, which is helpful to effectively prevent the traction shell 348 from being separated from the port of the formed water pipe during traction;

[0058] S5, first traction: through the conveying of the first hydraulic cylinder 31, the two traction shells 348 pull the first coated formed water pipe and move it toward one end of the traction tube 12 until it is sleeved inside the two traction shells 348, which is conducive to the shape of the two traction shells 348 so that the extruded water pipe always maintains a tapered mouth;

[0059] S6, second wrapping: start the second hydraulic cylinder 52 to drive the second extension rod 53 downward to drive the first expansion plate 57 and the second expansion plate 58 to gradually merge, and at the same time, the first extrusion shell 572 and the second extrusion shell 582 are wrapped around the outside of the traction tube 12, and the second extension rod 53 continues to move downward, and through the setting of the connecting block 56, the connecting block 56 is tilted outward, and then the first extrusion shell 572 and the second extrusion shell 582 are driven to rotate on the outside of the traction tube 12, which is conducive to making one end of the traction tube 12 after wrapping more uniform, and there will be no large and small concave and convex state, and there will be no loose adhesion;

[0060] S7, second traction: transport the coated water pipe to the inside of the vacuum device 13 through the traction pipe 12.

[0061] The specific working principle of the present invention includes the following process:

[0062] First, start the extrusion forming device 11 to extrude the material into the shape of a water pipe. The first extruded material is not fully preheated. At this time, start the motor 22 on the cutting mechanism 2 again. The motor 22 drives the rotating shaft 23 to rotate clockwise, so that the transmission plate 24 is transmitted to the connecting plate 25 clockwise through the first transmission rod to rotate downward. The stressed transmission frame 26 and the scraper 27 can move vertically downward through the setting of the sliding rod 29 and the limiting hole 222, so that the second blade on the scraper 27 can first scrape off the material that is not fully preheated. After the transmission plate 24 rotates clockwise to 180 degrees, the transmission plate 24 starts to rotate upward clockwise, so that the first blade on the scraper 27 moves upward to scrape off the material that is not fully preheated again. The scraped material falls vertically downward on the inner bottom of the collecting shell 61.

[0063] After the incompletely preheated material is cut off (the extrusion forming device 11 has stopped running), the first hydraulic cylinder 31 is started to drive the first extension rod 33 to move to one side. The first extension rod 33 is forced to drive the moving block 33 to one side, and the moving block 33 drives the telescopic rod 341, the traction plate 346, and the traction shell 348 to move to one side. Among them, the telescopic rod 341 cooperates with the guide rod 342 and the guide rail frame 343. At this time, the two traction shells 348 have been matched to form a trumpet shape. During the movement of the moving block 33, until one end of the two traction shells 348 is inserted into the molding port on the extrusion forming device 11, the movement stops, as shown in FIG. Figure 5As shown, the extrusion forming device 11 is started again to extrude the material into a water pipe, and the extruded water pipe is wrapped toward one end of the two traction shells 348. The length of the extruded water pipe extends to a length that allows the wrapping shell 4292 to wrap it. After the length of the extruded water pipe extends a certain distance.

[0064] The first hydraulic cylinder 31 is started, and the resistance block 41 is forced to move to one side. The two sides of the resistance block 41 will resist the resistance rod 421. The resistance rod 421 is forced to gradually move to one side, wherein the first pressure plate 4211 is pressed to one side against the lower part of the H-shaped plate 425, and the second pressure plate 4212 is forced to squeeze the first spring body 422 to one side. At the same time, the second guide rod 423 is forced to slide to one side inside the first through hole 4241, and the H-shaped plate 425 rotates clockwise on the outside of the first bearing rod 426, and the upper part of the H-shaped plate 425 is pressed against the third pressure plate 4 28, so that the third guide rod 4281 slides to one side and inside the second through hole 4242, and the pressure plate 4282 is pressed to one side by the second spring body 4283, and the gradual movement of the third pressure plate 428 is transmitted to the wrapping frame 429, and the wrapping rod 4291 and the wrapping shell 4292 are forced to move to one side. At the same time, the two wrapping shells 4292 gradually cooperate with each other, wherein the two traction shells 348 also move to one side and pull the squeezed water pipe to move to one side. At this time, the two wrapping shells 4292 are completely wrapped on the outside of one end of the two traction shells 348.

[0065] After the abutment rod 421 slides over the raised points on the two sides of the abutment block 41, the two wrapping shells 4292 return to their original positions by utilizing the elastic force of the second spring body 4283 and the first spring body 422, and the moving block 33 continues to move to one side, so that the two traction shells 348 continue to traction and extrude the water pipes, until the interior of the two traction shells 348 penetrates one end of the traction tube 12, wherein, as long as a part of the traction water pipe is covered on one end of the traction tube 12, the first hydraulic cylinder 31 can be stopped, and the second hydraulic cylinder 52 is started to drive the second extension rod 53 to move downward, so that the connecting plate 55 is transmitted to the connecting block 56, and the first expansion plate 57 and the second expansion plate 58 are forced to move downward, wherein the first roller 575 and the second roller 585 on the first extrusion shell 572 and the second extrusion shell 582 first abut against the outer side of the traction water pipe covered on the traction tube 12, and the first roller 575 and the second roller 585 are rolled to make the first and second expansion plates 57 and 586 move downward. The first extrusion shell 572 and the second extrusion shell 582 are gradually expanded outward through the fifth transmission rod until they are wrapped around the outside of the traction tube 12 and the pulled water pipe. The connecting block 56 continues to move downward, so that the first expansion plate 57 and the second expansion plate 58 continue to retract downward. At the same time, the first expansion plate 57 and the second expansion plate 58 are gradually merged and completely wrapped around the outside of the traction tube 12 and the pulled water pipe. The second hydraulic cylinder 52 can also continue to move downward, so that the connecting plate 55 can be gradually tilted. The inclination of the connecting plate 55 is used to allow the first extrusion shell 572 and the second extrusion shell 582 to rotate counterclockwise for a distance (the rotation angle is related to the length of the connecting plate 55). The first extrusion shell 572 and the second extrusion shell 582 are provided with a first extrusion ridge 576 and a second extrusion ridge 586 inside, so that the wrapped water pipe can be evenly attached to one end of the traction tube 12 (can continuously reciprocate up and down).

[0066] After the pulled water pipe is fixed, the first hydraulic cylinder 31 is started again to drive the moving block 33 to continue to move to one side, and the first guide rod 342 continues to move to one side along the guide rail frame 343, and is gradually guided to the inclined track, so that the telescopic rods 341 on both sides slide to both sides at the same time inside the telescopic hole 331, and then the two pulling shells 348 are gradually separated, so that the water pipe attached to the extruded water pipe can be separated (before this, the reciprocating rotation of the first extrusion shell 572 and the second extrusion shell 582 can disconnect the extruded water pipe covered by the two pulling shells 348). After the two pulling shells 348 are separated, the first hydraulic cylinder 31 is stopped, and the second hydraulic cylinder 52 is started again to move to the original position, and then the pulling tube 12 is used to transport the covered water pipe to the inside of the vacuum device 13.
