Description

Technical Field

[0001] The present invention relates to the technical field of PE pipe production, and in particular to a forming device and method for a high-strength antibacterial PE water supply pipe. Background Art

[0002] PE stands for polyethylene. PE pipes are generally used for water supply pipes at temperatures below 40°C and cannot be used for hot water distribution. Pipes made from polyethylene raw material have excellent corrosion resistance, flexibility, low-temperature resistance, fracture toughness, and are rust-resistant and scale-resistant. In the current trend of replacing steel with plastic, PE pipes are widely used in pipeline production. Polyethylene can be categorized by density into high-density polyethylene, medium-density polyethylene, low-density polyethylene, and linear low-density polyethylene.

[0003] In the prior art, when the traction member is pulling the material, the port of the extruded material will shrink and fall downward, so that the port of the material cannot be covered on the outside of the traction tube, resulting in the port of the material being unable to fully adhere to one end of the traction tube. When the traction tube moves, the material will be separated from one end of the traction tube, thereby reducing work progress, work efficiency, and work performance.

[0004] In order to solve the above problems, the present invention proposes a high-strength antibacterial PE water supply pipe forming device and method. Summary of the Invention

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 includes a support frame 1, an extrusion forming device 11 is provided on the upper end face of the support frame 1, a forming port on the extrusion forming device 11 is 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 outside of the traction tube 12; and the support legs on the support frame 1 are fixedly connected to a collection shell 61 via a fixing rod 6.

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 clockwise force is transmitted downward to the transmission frame 26, 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 fully 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 fully preheated. The scraped material falls vertically downward on the inner bottom of the collection shell 61. Through the setting of the scraper 27, the scraped material falls vertically downward, avoiding the scraped material from falling anywhere else. Moreover, one operation can scrape twice, effectively improving the removal efficiency.

[0046] In this embodiment, the traction mechanism 3 includes a first hydraulic cylinder 31 fixedly connected to the supporting frame 1 bearing plate, the output end of the first hydraulic cylinder 31 is connected to the first extension rod 32, one end of the first extension rod 32 is fixedly connected to the moving block 33, the moving block 33 has telescopic holes 331 on both sides, and the two telescopic holes 331 are each provided with a first traction assembly 34 and a second traction assembly 35.

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 driven by the force 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 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 forming 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 to a certain distance, the shape of the two traction shells 348 allows the extruded water pipe to always maintain a tapered mouth, effectively avoiding the traction tube from pulling the extruded water pipe, and allowing the port of the extruded water pipe to continue to remain open, so that the port of the extruded water pipe is 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.

[0047] In this embodiment, one end of the two traction shells 348 is inserted into the inner side of the extrusion port of the extrusion forming device 11. This is beneficial for the extruded water pipe to be better covered with the outer shape of the two traction shells 348.

[0048] In this embodiment, the wrapping mechanism 4 includes a resistance block 41 fixedly connected to one end of the extension rod 32, and both sides of the resistance block 41 are in resistance with a first wrapping component 42 and a second wrapping component 43.

A second guide rod 423 is fixedly connected in the middle, and one end of the second guide rod 423 passes through a first through hole 4241 provided at the lower part of the second L-shaped plate 424. One end of the first spring body 422 is fixedly connected to a side surface of the second L-shaped plate 424. An H-shaped plate 425 is in contact with the first pressure plate 4211 and the second pressure plate 4212. The H-shaped plate 425 is rotatably matched with the first supporting rod 426 through the rotating hole 4251. Both ends of the first supporting rod 426 are fixedly connected to a support frame 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. The resistance rod 421 gradually moves to one side along the convex surface of the resistance block 41. After the resistance rod 421 is subjected to force, it is pressed to one side by the first pressure plate 4211 against the lower part of the H-shaped plate 425, wherein the second pressure plate 4212 is squeezed to one side by 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-shaped plate 425 is subjected to the resistance pressure from the lower part, it rotates clockwise on the outside of the first bearing rod 426. Through the setting of the H-shaped plate 425, the moving power can be converted into the opposite movement, so that the two wrapping shells 4292 can be wrapped.

[0049] In this embodiment, the upper part of the H-shaped plate 425 is abutted against and connected to a third pressure plate 428, and one side of the third pressure plate 428 is fixedly connected to a third guide rod 4281, and one end of the third guide rod 4281 passes through the interior of the second through hole 4242 opened on the upper part of the L-shaped plate 424, and one end of the third guide rod 4281 is fixedly connected to a pressure plate 4282, and one side of the pressure plate 4282 is fixedly connected to a second spring body 4283, and one end of the second spring body 4283 is fixedly connected to one side of the upper part of the second L-shaped plate 424, and one side of the third pressure plate 428 is fixedly connected to a parcel rack 429, and the upper part of one side of the parcel rack 429 is fixedly connected to a parcel rod 4291, and one end of the parcel rod 4291 is fixedly connected to a parcel shell 4292, and the first parcel component 42 and the second parcel component 43 have the same structure, and the two parcel shells 4292 cooperate in a trumpet shape. The upper part of the H-shaped plate 425 is pressed against the third pressing plate 428, and the third guide rod 4281 is subjected to the force transmitted by the third pressing plate 428 to one side, 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 with the power of the third guide rod 4281, and is gradually moved and transmitted to the parcel rack 429. The parcel rack 429 is subjected to the force transmitted to the parcel rod 4291 and the parcel shell 4292 to one side. At the same time, the two parcel 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 parcel shells 4292 are completely wrapped around the outside of one end of the two traction shells 348. Through the squeezing of the wrapping shell 4292, the traction shell 348 is effectively prevented from being separated during traction.

[0050] In this embodiment, the interiors of the two wrapping shells 4292 are wrapped around the outsides of the two traction shells 348. This helps to better adhere the traction pipe to the outside of one end of the traction shell 348.

The connecting plate 55 is driven downward by the force to drive the connecting block 56. The connecting block 56 presses downward on the first expansion plate 57 and the second expansion plate 58. Among them, the first roller 575 and the second roller 585 on the first extrusion shell 572 and the second extrusion shell 582 first contact the outside of the traction pipe wrapped on the traction pipe 12. By rolling the first roller 575 and the second roller 585, the first extrusion shell 57 2 and the second extruded 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, causing the first expansion plate 57 and the second expansion plate 58 to 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. Through the extrusion of the first extruded shell 572 and the second extruded shell 582, it can be ensured that the pulled water pipe is better wrapped around the outside of the traction tube 12.

The second hydraulic cylinder 52 can further move downward, causing the connecting plate 55 to gradually tilt, and the tilt of the connecting plate 55 can be used to allow the first extrusion shell 572 and the second extrusion shell 582 to rotate counterclockwise for a certain distance, wherein 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, and through the reciprocating rotation of the first extrusion shell 572 and the second extrusion shell 582, the wrapped end of the traction tube 12 is more uniform, and there will be no large and small concave and convex state, and no loose attachment.

[0053] A method for using a high-strength antibacterial PE water supply pipe forming device, the specific steps are as follows:

[0054] S1, forming: start the extrusion forming device 11 to extrude the material into the shape of a water pipe;

[0055] S2. Scraping: Start the motor 22 to drive the transmission frame 26 and the scraper 27 to move vertically downward, so that the first blade and the second blade of the scraper 27 can cut off the material that has not been fully preheated. This can achieve two scraping operations in one operation, which can improve the cutting efficiency.

[0056] S3. Docking: The first hydraulic cylinder 31 is activated to drive the moving block 33 to move the traction shell 348 to one side. The first guide rod 342 and the guide rail 343 cooperate to make the two traction shells 348 fit together into a trumpet shape. During the movement of the moving block 33, one end of the two traction shells 348 is inserted into the forming port of the extrusion forming device 11, which helps the extruded water pipe to better cover the outer shape of the two traction shells 348.

[0057] S4, first wrapping: The first hydraulic cylinder 31 is activated to drive the resistance block 41, causing the resistance rod 421 to move to one side. The H-shaped plate 425 then converts the power to move the third guide rod 4281 to the other side, driving the two wrapping shells 4292 to wrap around the outside of the two traction shells 348, which is helpful in effectively preventing the traction shells 348 from being separated from the ends of the formed water pipe during traction.

[0058] S5. First traction: The first hydraulic cylinder 31 is used to pull the first wrapped formed water pipe by the two traction shells 348 and move it toward one end of the traction tube 12 until it is sleeved inside the two traction shells 348. This helps the shape of the two traction shells 348 to keep the extruded water pipe tapered.

[0059] S6. Second wrapping: The second hydraulic cylinder 52 is activated to drive the second extension rod 53 downward, driving the first expansion plate 57 and the second expansion plate 58 to gradually merge. At the same time, the first extrusion shell 572 and the second extrusion shell 582 wrap around the outside of the traction tube 12. 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, thereby driving the first extrusion shell 572 and the second extrusion shell 582 to rotate around the outside of the traction tube 12. This is conducive to making one end of the traction tube 12 more uniform after wrapping, and there will be no uneven state of one large and one small, and 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 force-bearing 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 scrape off the material that is not fully preheated first. 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 to the inner bottom of the collection 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 driven by the force 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 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 forming port on the extrusion forming device 11, the movement stops. Figure 5As shown, the extrusion forming device 11 is started again to extrude the material out of the 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 is extended to allow 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 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, 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 forced to squeeze to one side on the second spring body 4283, and the gradual movement of the third pressure plate 428 is transmitted to the parcel rack 429, and the parcel rod 4291 and the parcel shell 4292 are forced to move to one side. At the same time, the two parcel 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 parcel shells 4292 are completely wrapped around the outside of one end of the two traction shells 348.

[0065] After the interference rod 421 slides over the raised points on both sides of the interference block 41, the two wrapping shells 4292 return to their original positions by virtue of the elastic force of the second spring body 4283 and the first spring body 422. When the moving block 33 continues to move to one side, the two traction shells 348 continue to traction the extruded water pipes until the interior of the two traction shells 348 passes through one end of the traction tube 12. 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. Then, 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. The first expansion plate 57 and the second expansion plate 58 are forced to move downward. The first rollers 575 and the second rollers 585 on the first extrusion shell 572 and the second extrusion shell 582 first contact the outside of the traction water pipe covered on the traction tube 12, and the first rollers 575 and the second rollers 585 are rolled to make 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, causing the first expansion plate 57 and the second expansion plate 58 to 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, causing the connecting plate 55 to gradually tilt. The tilt 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 certain 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, which can make the wrapped water pipe evenly attached to one end of the traction tube 12 (can continuously move back and forth up and down).

[0066] After fixing the pulled water pipe, the first hydraulic cylinder 31 is started again to drive the moving block 33 to continue to move to one side, and its first guide rod 342 continues to move to one side along the guide rail frame 343, gradually guiding it 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 gradually separate the two traction shells 348, 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 traction shells 348). After separating the two traction shells 348, the first hydraulic cylinder 31 is stopped, and the second hydraulic cylinder 52 is started again to move it to the original position, and then the traction tube 12 is used to transport the covered water pipe to the inside of the vacuum device 13.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
