Description

Technical Field

[0001] The present invention relates to the technical field of pipeline production, and in particular to a production process of a pressure-resistant pipe for a coffee machine. Background Art

[0002] With the development of modern industry, plastic products are playing an increasingly important role in people's lives. As essential equipment for conveying fluids or gases, pipes are attracting increasing attention for their production quality and efficiency. The extruder's operating process is roughly as follows: raw materials enter the barrel from a hopper, where they are melted and fully plasticized by a heating device, forming a uniform melt. The material then enters the extruder's screw through the discharge port (i.e., the outlet at the lower end of the barrel). The screw then propels the molten material forward along the barrel. The melt is then extruded through a die, forming a continuous pipe shape. The pipe extrusion mechanism offers advantages such as high production efficiency, stable product quality, and the ability to manufacture pipes of various specifications and materials. It has found widespread application in the manufacture of plastic and metal pipes.

[0003] However, in the process of melting plastic particles, incomplete melting of particles may occur, which reduces the efficiency of the fusion process. Moreover, the melted liquid flows downward on the discharge port. After long-term use, the inner wall of the discharge port is adhered to the liquid and the solid after the liquid is fixed, causing the discharge port to be blocked. It is inconvenient for manual cleaning, increases the workload, and reduces practicality. In particular, the viscosity of the liquid effectively slows down the speed at which the liquid flows to the screw, reducing the progress of the work.

[0004] In order to solve the above problems, the present invention proposes a production process for a pressure-resistant tube of a coffee machine. Summary of the Invention

[0050] The pipe extrusion molding device in the operation process of the above-mentioned process step S2 includes a hot melt barrel 1, the lower end of the hot melt barrel 1 is connected to a discharge port 2, and the lower end of the discharge port 2 is connected to the pipe extrusion molding device body 3; an electric heating ring 14 is provided on the outside of the hot melt barrel 1; a partition 11 is fixedly connected to the middle of the hot melt barrel 1, and a sliding hole 111 is opened inside the partition 11; an auxiliary mechanism 5 is provided inside the hot melt barrel 1.

[0051] In this embodiment, the upper end surface of the partition 11 and the upper portion of the hot melt barrel 1 form a first accommodating chamber 12, and the lower end surface of the partition 11 and the lower portion of the hot melt barrel 1 form a second accommodating chamber 13. A feed pipe 14 is connected to one side of the outer surface of the hot melt barrel 1, and one end of the feed pipe 14 is connected to the upper portion of the inner surface of the second accommodating chamber 13. The division of the first accommodating chamber 12 and the second accommodating chamber 13 allows the first accommodating chamber 12 to protect the rotating disc 55 during its lifting and lowering operation, while the second accommodating chamber 13 is used to place, melt, and guide the plastic pellets.

[0052] In this embodiment, the auxiliary mechanism 5 includes a support frame 51, the lower end surface of the support frame 51 is fixed to the upper end surface of the hot melt barrel 1, and the support frame 51 is internally fixed with a motor 52, the output end of the motor 52 is connected to a rotating shaft 53, the upper end of the rotating shaft 53 is inserted into the rotating hole on the upper end surface of the hot melt barrel 1, and the lower end of the rotating shaft 53 is fixedly connected to a sliding disc 531, the outer ring surface of the sliding disc 531 is fixedly connected to sliders 532 on both sides, and the sliding disc 531 is slidably fitted in the fixed cylinder 54. Inside the telescopic hole 541, vertical slide grooves 542 are provided on both sides of the inner surface of the telescopic hole 541, and the slider 532 slides in the vertical slide grooves 542. A through hole 543 is provided on the upper end surface of the fixed cylinder 54, and the lower end of the through hole 543 is communicated with the inside of the telescopic hole 541, and the inside of the through hole 543 slides in the outside of the rotating shaft 53. A rotating disk 55 is fixed on the lower end surface of the fixed cylinder 54, and a spring body 56 is connected to the bottom of the telescopic hole 541 and the lower end surface of the rotating shaft 53.The starting motor 52 drives the rotating shaft 53 to rotate clockwise. The rotating shaft 53 is driven by the force to drive the sliding disc 531 to rotate clockwise. The sliding disc 531 is driven by the force through the slider 532 to drive the fixed cylinder 54 and the rotating disc 55 to rotate clockwise. The rotating disc 55 drives the fixed rod 57, the transmission plate 571 and the transmission ball 572 to rotate clockwise. At the same time, the rotating disc 55 drives the sliding cylinder 58 to rotate inside the sliding hole 111. The sliding cylinder 58 drives the support rod 581 and the first scraper plate 582 to rotate clockwise. The transmission ball 572 slides inside the lifting ring groove 573. The transmission ball 572 is guided by the lifting ring groove 573 to gradually slide downward. At this time, the transmission ball 572, the transmission plate 571 and the fixed rod 57 drive the rotating disc 55 to gradually move downward. At this time, the rotating disc 55 is forced to move downward on the sliding cylinder 58. The sliding cylinder 58 is forced to slide downward inside the sliding hole 111, and the sliding cylinder 58 also drives the support rod 581 and the first scraper ring downward. Plate 582, at the same time, the rotating disc 55 drives the fixed cylinder 54 downward to move downward, wherein the telescopic hole 541 slides downward on the sliding disc 531, the vertical slide groove 542 slides vertically downward on the slider 532, and the through hole 543 slides downward on the outside of the rotating shaft 53 and is stretched downward on the spring body 56 until the transmission ball 572 slides to the low point of the lifting ring groove 573. At this time, the lower end surface of the first scraper ring 582 contacts the inclined surface of the annular block 552, and the rotating disc 55 is located in the second accommodating chamber 1 At the connection point of the conical surface at the bottom of the rotating disc 55, the transmission ball 572 slides upward inside the lifting ring groove 573, causing the rotating disc 55, the fixed cylinder 54, and the sliding cylinder 58 to move upward. The spring body 56 gradually returns to its original position until the transmission ball 572 slides to the height of the lifting ring groove 573. At this point, the edge of the upper end surface of the rotating disc 55 contacts the lower end surface of the annular block 552, and the upper end surface of the first scraper plate 582 approaches the lower end surface of the partition 11, thereby completing the rotation and lifting of the rotating disc 55. The rotation and lifting of the rotating disc 55 accelerates the melting of the plastic particles, allowing the unmelted particles to remain on the upper end surface of the rotating disc 55, ensuring uniform melting of each plastic particle, improving melting efficiency, and at the same time, enhancing the quality of the extruded pipe.

[0053] In this embodiment, the rotating disc 55 is provided with leak holes 551 at equal angles in an annular pattern. The edge of the upper end surface of the rotating disc 55 abuts against an annular block 552. The outer surface of the annular block 552 is fixed to the middle of the inner surface of the second accommodating chamber 13. The lower end surface of the rotating disc 55 is fixedly connected to a transmission rod 553. The lower end surface of the transmission rod 553 is fixedly connected to a connecting rod 554. The lower end surface of the connecting rod 554 is fixedly connected to a connecting plate 555. The annular surface of the rotating disc 55 abuts against the interior of the second accommodating chamber 13. The first scraping plate 582 and the rotating disc 55 are lifted and lowered to reciprocate and scrape away liquid adhering to the inner surface of the second accommodating chamber 13. The liquid scraped away by the first scraping plate 582 is guided to the upper end surface of the rotating disc 55 by the annular block 552. The liquid scraped away by the rotating disc 55 flows to the conical surface of the second accommodating chamber 13, thereby preventing the liquid from hardening on the inner surface of the second accommodating chamber 13 and eliminating the need for manual cleaning, thereby improving practicality.

[0054] In this embodiment, fixed rods 57 are fixedly connected to both sides of the middle of the upper end surface of the rotating disc 55. A transmission plate 571 is fixedly connected to the upper end surface of the fixed rods 57. A transmission ball 572 is fixedly connected to one side of the transmission plate 571. The transmission ball 572 slidably fits within a lifting ring groove 573 defined on the inner side of the first accommodating chamber 12. The lifting ring groove 573 guides the rotating disc 55 to be raised and lowered.

[0055] In this embodiment, a sliding cylinder 58 is fixedly connected to the middle of the upper end surface of the rotating disk 55. Support rods 581 are fixedly connected to both sides of the upper outer surface of the sliding cylinder 58. One end of the support rod 581 is fixedly connected to a first scraper plate 582. The outer surface of the first scraper plate 582 contacts the inner surface of the second accommodating cavity 13. The scraping of the first scraper plate 582 scrapes the inner surface of the second accommodating cavity 13.

[0056] In this embodiment, the outer surface of the upper end of the sliding cylinder 58 slides within the sliding hole 111, and the fixed cylinder 54 and the two fixed rods 57 are located within the sliding cylinder 58. The sliding fit between the sliding cylinder 58 and the sliding hole 111 prevents liquid from contaminating the interior of the first accommodating chamber 12, thereby preventing the transmission ball 572 and the lifting ring groove 573 from being contaminated by liquid, thereby increasing the service life of the transmission ball 572 and the lifting ring groove 573.

[0057] In this embodiment, scrapers 59 are fixedly connected to both sides of the connecting plate 555. The scrapers 59 include a second scraper plate 591. A fixing plate 592 is fixedly connected to both sides of the lower end surface of the second scraper plate 591. A third scraper plate 593 is fixedly connected to the lower end surface of the fixing plate 592. A first conveying plate 594 is fixedly connected to the inner surface of the second scraper plate 591. A second conveying plate 595 is fixedly connected to the inner surface of the third scraper plate 593. The rotating disc 55 drives the transmission rod 553, the connecting rod 554, and the connecting plate 555 to move upward and downward, and the connecting plate 555 drives the scraper 59 to move upward and downward. The scraper 59 scrapes liquid adhering to the discharge port 4 via the second scraper plate 591 and the third scraper plate 593. Furthermore, the downward pressure of the first conveying plate 594 and the second conveying plate 595 accelerates the delivery of liquid flowing through the discharge port 4. Increasingly, the liquid and fixed solids on the inner surface of the discharge port 2 can be scraped and cleaned to avoid clogging of the discharge port 2. No manual cleaning is required, which improves practicality, speeds up the flow of liquid, and improves work progress.

[0058] In this embodiment, the outer side of the scraper 59 is slidably fitted inside the discharge port 2, which is beneficial for scraping liquid from the inner surface of the discharge port 2.

[0059] The specific working principle of the present invention includes the following process:

[0060] First, the motor 52 is started to drive the rotating shaft 53 to rotate clockwise. The rotating shaft 53 is driven by force to drive the sliding disc 531 to rotate clockwise. The sliding disc 531 is driven by force through the slider 532 to drive the fixed cylinder 54 and the rotating disc 55 to rotate clockwise. The rotating disc 55 drives the fixed rod 57, the transmission plate 571 and the transmission ball 572 to rotate clockwise. At the same time, the rotating disc 55 drives the sliding cylinder 58 to rotate inside the sliding hole 111. The sliding cylinder 58 drives the support rod 581 and the first scraper ring. The plate 582 rotates clockwise, wherein the transmission ball 572 slides inside the lifting ring groove 573. The transmission ball 572 is guided by the lifting ring groove 573 to gradually slide downward. At this time, the transmission of the transmission ball 572, the transmission plate 571 and the fixed rod 57 causes the rotating disc 55 to gradually move downward. At this time, the rotating disc 55 is forced downward to drive the sliding cylinder 58. The sliding cylinder 58 is forced to slide downward inside the sliding hole 111, and the sliding cylinder 58 also drives downward. The support rod 581 and the first scraper plate 582, at the same time, the rotating disc 55 drives the fixed cylinder 54 to move downward, wherein the telescopic hole 541 slides downward on the sliding disc 531, the vertical slide groove 542 slides vertically downward on the slider 532, and the through hole 543 slides downward on the outside of the rotating shaft 53 and is stretched downward on the spring body 56 until the transmission ball 572 slides to the low point of the lifting ring groove 573. At this time, the lower end surface of the first scraper plate 582 contacts the inclined surface of the annular block 552. The rotating disc 55 is located at the connection of the conical surface at the lower part of the second accommodating chamber 13. When the transmission ball 572 slides upward inside the lifting ring groove 573, the rotating disc 55, the fixed cylinder 54 and the sliding cylinder 58 move upward, and the spring body 56 gradually resets until the transmission ball 572 slides to the height of the lifting ring groove 573. At this time, the edge of the upper end surface of the rotating disc 55 contacts the lower end surface of the annular block 552, and the upper end surface of the first scraper ring 582 is close to the lower end surface of the partition 11 (such as Figure 3 As shown), the rotation and lifting of the rotating disc 55 are completed.

[0061] Then, the plastic particles are guided into the second accommodating chamber 13 through the feeding pipe 14, and fall onto the upper end surface of the rotating disc 55 that rotates and rises simultaneously, so that the plastic particles are evenly distributed on the upper end surface of the rotating disc 55. After being covered, the electric heating ring 14 is started to heat the second accommodating chamber 13. During the reheating process, the rotating disc 55 that rotates and rises simultaneously is used to move the plastic particles away from the center of the rotating disc 55 and concentrate them at the intersection of the inner surface of the second accommodating chamber 13 and the outer ring surface of the rotating disc 55 (to avoid the phenomenon that the plastic particles located in the middle of the rotating disc 55 are heated at different temperatures and the plastic particles are not completely melted). This can accelerate the melting speed of the plastic particles. Among them, the size of the leakage hole 551 is not enough for the plastic particles to pass through. After the particles are completely heated, the plastic particles melt into liquid, and the rotating disc 55 and the leakage hole 551 that rotate and rise and fall simultaneously can drop the liquid downward onto the conical surface at the lower part of the second accommodating chamber 13. Among them, the liquid attached to the inner surface of the second accommodating chamber 13 can be scraped back and forth by the lifting first scraper plate 582 and the rotating disc 55. The liquid scraped by the first scraper plate 582 is guided to the upper end surface of the rotating disc 55 through the annular block 552, and the liquid scraped by the rotating disc 55 flows to the conical surface on the second accommodating chamber 13.

[0062] The liquid flows into the inside of the discharge port 2 through the guidance of the conical surface. At the same time, the scraper 59 accelerates the flow of the downward-flowing liquid. The scraper 59 slides up and down inside the discharge port 2 through the rotation and lifting power of the rotating disc 55. The rotating disc 55 drives the transmission rod 553, the connecting rod 554 and the connecting plate 555 to lift and rotate. The connecting plate 555 drives the scraper 59 to lift and rotate. The scraper 59 scrapes the liquid (the liquid has viscosity) attached to the discharge port through the second scraper ring plate 591 and the third scraper plate 593. In addition, the downward stamping of the first conveying plate 594 and the second conveying plate 595 can accelerate the conveying of the liquid flowing in the discharge port, so that the flowing liquid can quickly flow into the pipe extrusion molding device body, thereby completing the production of the pipe.

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.
