Description

Technical Field

[0001] This invention relates to the field of hose manufacturing technology, specifically a multi-layer hose processing device and processing method. Background Technology

[0002] Multi-layer hoses consist of three layers. The outer layer is a traditional hose design; the inner layer is a specially designed hose with several small holes of similar diameter, regularly distributed around its perimeter; and 3 to 5 flexible bridging structures are installed between the inner and outer layers. The hose has good straightness, and the flexible bridging structures can stretch or contract under stress, helping the hose maintain a certain degree of straightness. The presence of the inner tubes and bridging structures effectively prevents the inner wall of the hose from completely adhering, thus ensuring smooth and efficient liquid delivery. The multi-layer hose design divides the inner cavity into 3 to 6 relatively independent yet interconnected tubes. This changes the way sediments are deposited in the liquid, causing them to be evenly deposited in the lower part of the tube as the liquid flows, reducing the risk of tube blockage and extending the service life of the hose.

[0003] Traditional processing equipment is mostly designed for double-layer or single-layer hoses. It cannot effectively create a flexible bridging structure between the outer and inner layers of the hose. Often, the inner layer is processed first, followed by the flexible bridging structure, and finally the outer layer. This multi-step process results in longer processing times and reduced efficiency. Furthermore, traditional hose processing equipment struggles to simultaneously create a small hole with a diameter equal to the inner diameter of the hose. Drilling is usually performed after the hose is processed, further impacting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-layer hose processing apparatus and processing method to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-layer hose processing device includes a support base, a conveying mechanism, a first forming mechanism, a second forming mechanism, a traction mechanism, a hose winding mechanism, and a cooling box. The support base and the conveying mechanism are fixedly connected, the conveying mechanism and the first forming mechanism are fixedly connected, the first forming mechanism and the second forming mechanism are fixedly connected, the conveying mechanism, the first forming mechanism, the second forming mechanism, the traction mechanism and the hose winding mechanism are arranged sequentially along the processing direction, and the cooling box and the support base are fixedly connected.

[0007] The support base supports the conveying mechanism, the first forming mechanism, and the second forming mechanism. The conveying mechanism transports the material for forming the hose to the first forming mechanism, where it is cooled. A cooling box accelerates the cooling process, causing the material to change from a liquid to a solid state, forming the inner tube and elastic bridge structure of the multi-layered hose. The conveying mechanism continues to transport the liquid material, pushing the initially formed hose into the second forming mechanism. Some of the liquid material flows into the second forming mechanism along with the initially formed hose. This liquid material is cooled to form the outer tube of the multi-layered hose, thus forming a multi-layered hose. The cooling box further cools the hose to prevent deformation. The traction mechanism precisely pulls the hose according to preset length parameters, thus achieving hose delivery. The winding mechanism neatly winds the finished hose onto a reel.

[0008] Furthermore, the No. 1 forming mechanism includes a fixed rod, a core tube, a No. 1 tube mold, a No. 1 sliding plate, a No. 2 sliding plate, and a control unit. The fixed rod is fixedly connected to the No. 1 tube mold, the fixed rod is fixedly connected to the core tube, and the No. 1 tube mold is fixedly connected to the conveying mechanism. The No. 1 tube mold has several No. 1 sliding grooves, and the No. 1 sliding plate has several sliding connections, each slidingly connected to one of the No. 1 sliding grooves. The No. 1 tube mold has several No. 2 sliding grooves, and the No. 2 sliding plate has several sliding connections, each slidingly connected to one of the No. 2 sliding grooves. The No. 1 sliding plate has several fixed connections, and the No. 2 sliding plate has several fixed connections. The No. 1 tube mold has a No. 1 flow groove, and the No. 1 sliding plate has a No. 2 flow groove. The No. 2 flow groove is arc-shaped and communicates with the No. 1 flow groove. The No. 2 sliding plate has several protrusions that abut against the core tube.

[0009] The tube core is fixed by fixing one end of a fixed rod to the first tube mold and the other end to the tube core. The first tube mold has a first flow groove, and the first slide plate has a second flow groove. The material for processing multi-layer hoses flows from the conveying mechanism into the first and second flow grooves. The second flow groove is arc-shaped, so that the processing material of the multi-layer hose forms an arc-shaped elastic bridge structure in the second flow groove. By having several first slide plates, the elastic bridges are distributed along the hose axis. The processing material of the multi-layer hose cools in the first flow groove to form the inner layer of the multi-layer hose. Several second slide plates have several protrusions that abut against the tube core, so that the inner layer of the hose forms several small holes along the hose axis. The second flow groove is connected to the first flow groove, so that the inner layer of the multi-layer hose and the elastic bridge structure are fixedly connected. By the control unit, the first slide plate slides into the first sliding groove, and the second slide plate slides into the second sliding groove. The conveying mechanism continues to convey the processing material, so that the initially formed multi-layer hose is pushed to the second forming mechanism.

[0010] Furthermore, the second forming mechanism includes a second tube mold, a first outer shell, a third sliding plate, a spring, a baffle, a connecting block, a fixing block, a first motor, and a first rotating shaft. The second tube mold is fixedly connected to the first tube mold, and the second tube mold is provided with a placement groove. The first outer shell is fixedly connected to the first tube mold, and the second tube mold is provided with a third sliding groove. The third sliding plate is slidably connected to the third sliding groove, and the spring is set in the third sliding groove. The spring and the third sliding plate are fixedly connected. The fixing block is fixedly connected to the first outer shell, the first motor is fixedly connected to the fixing block, the output end of the first motor is fixedly connected to the first rotating shaft, the first rotating shaft is drivenly connected to the connecting block, the baffle is fixedly connected to the connecting block, and the first outer shell is provided with a third flow groove.

[0011] The pre-formed multi-layered hose is pushed into the placement groove by the No. 2 tube mold when the processing material is conveyed by the conveying mechanism. The material flows into the No. 3 flow groove between the No. 1 outer shell and the No. 2 tube mold. The material cools in the flow groove to form the outer layer of the multi-layered hose. The outer layer of the hose is fixedly connected to the elastic bridge structure through the placement groove and the No. 3 flow groove, thus forming several relatively independent but connected channels between the outer and inner layers of the hose. The No. 1 motor is fixed by the fixing block. The output end of the No. 1 motor is connected to the No. 1 rotating shaft. The No. 1 motor drives the No. 1 rotating shaft to rotate, causing the baffle to flip, thus connecting the placement groove and the No. 3 flow groove to the outside. The processing material continues to be conveyed by the conveying mechanism, which pushes the multi-layered hose. The No. 3 slide plate slides into the No. 3 sliding groove, pushing the multi-layered hose outside the No. 2 forming mechanism. The pre-formed multi-layered hose is then pushed back to the placement groove. The No. 3 slide plate is reset under the action of the spring, and the processing material continues to flow into the No. 3 flow groove, thus continuously generating multi-layered hoses.

[0012] Furthermore, the control unit includes an electric cylinder, a first connecting rod, a second connecting rod, a third connecting rod, a fourth connecting rod, and a fifth connecting rod. The electric cylinder is fixedly connected to the first tube mold, and the output end of the electric cylinder is fixedly connected to the first connecting rod. The first tube mold is provided with a fourth sliding groove, and the first connecting rod is slidably connected to the fourth sliding groove. The first tube mold is provided with a fifth sliding groove, and the second connecting rod is slidably connected to the fifth sliding groove. The second connecting rod is fixedly connected to the first connecting rod, the third connecting rod is slidably connected to the fifth sliding groove, the third connecting rod is fixedly connected to the second connecting rod, the third connecting rod is fixedly connected to the first sliding plate, the fourth connecting rod is fixedly connected to the first connecting rod, and the fifth connecting rod is slidably connected to the fourth connecting rod. The first tube mold is provided with a sixth sliding groove, and the fourth connecting rod is slidably connected to the sixth sliding groove.

[0013] The entire control unit is fixed to the No. 1 tube mold by an electric cylinder. The output end of the electric cylinder is fixedly connected to the No. 1 connecting rod. The output end of the electric cylinder extends, driving the No. 1 connecting rod to slide in the No. 4 sliding groove along the processing direction. The No. 1 connecting rod is fixedly connected to the No. 2 connecting rod, causing the No. 2 connecting rod to move with the No. 1 connecting rod. The conveying mechanism conveys material and pushes the initially formed multi-layer hose, causing the No. 1 sliding plate to slide into the No. 1 sliding groove. The No. 3 connecting rod is fixedly connected to the No. 1 sliding plate, causing the No. 3 connecting rod to slide into the No. 5 sliding groove. The No. 4 connecting rod is fixedly connected to the No. 1 connecting rod, causing the No. 2 sliding plate to slide into the No. 2 sliding groove. Thus, the initially formed multi-layer hose is pushed by the processing material along the processing method. The output end of the electric cylinder retracts, causing the No. 1, No. 2, No. 3, No. 4, and No. 5 connecting rods to reset, thereby continuing to form the initially formed multi-layer hose in the No. 1 tube mold.

[0014] Furthermore, the conveying mechanism includes a second outer casing, a second motor, a second rotating shaft, spiral blades, and a heating tube. The second outer casing is fixedly connected to the support base, the second motor is fixedly connected to the support base, the output end of the second motor is fixedly connected to the second rotating shaft, the spiral blades are fixedly connected to the second rotating shaft, and the second outer casing is provided with an installation groove, in which the heating tube is placed.

[0015] The conveying mechanism is fixed by the second outer shell and the support base. The second motor drives the second rotating shaft to rotate, which in turn rotates the spiral blades fixedly connected to the second rotating shaft, thereby moving the processed material along the processing direction. The second outer shell is provided with an installation groove, and a heating tube is installed in the installation groove, so that the processed material melts from solid to liquid during the movement and is then transported into the first tube mold.

[0016] Furthermore, the traction mechanism includes a No. 3 motor, a No. 1 fixed plate, rollers, and a conveyor belt. The No. 3 motor and the No. 1 fixed plate are fixedly connected. There are two No. 1 fixed plates and four rollers. The two No. 1 fixed plates and the four rollers are rotatably connected. The output end of the No. 3 motor is fixedly connected to one of the rollers. There are two conveyor belts located at different layer heights. The conveyor belts are sleeved on the two rollers.

[0017] The rollers are rotatably connected by two No. 1 fixed plates and fixed from both ends of the rollers. The No. 3 motor is connected to one of the rollers, so that the No. 3 motor drives the roller to rotate. This causes the conveyor belts fitted on the two rollers to rotate in the direction of the rollers' rotation. Since the two conveyor belts are located at different layer heights, the processed multi-layer hoses are transported according to the preset length.

[0018] Furthermore, the tube winding mechanism includes a No. 4 motor, a tube winding shaft, and a No. 2 fixing plate. There are two No. 2 fixing plates. The tube winding shaft and the two No. 2 fixing plates are rotatably connected. The No. 4 motor and the No. 2 fixing plate are fixedly connected. The output end of the No. 4 motor is fixedly connected to the tube winding shaft.

[0019] The hose reel is rotatably connected to two No. 2 fixing plates, which fixes both ends of the hose reel and allows it to rotate along its own axis. The No. 4 motor, which is fixed on one of the No. 2 fixing plates, drives the hose reel to rotate along its own axis, so that the processed hose is neatly wound on the hose reel.

[0020] A processing method for a multi-layer hose processing device includes the following steps:

[0021] S1: The second rotating shaft is driven by the second motor to rotate, thereby rotating the spiral blades and moving the processed material along the processing direction. During the movement of the processed material, the heating tube installed causes the processed material to melt from solid to liquid.

[0022] S2: The molten material is cooled in the No. 1 flow tank to form the inner layer of the multi-layer hose. Through the protrusions provided by the No. 2 slide plate, several small holes are formed in the inner layer hose along the hose axis. The material is cooled in the No. 2 flow tank to form an elastic bridge structure. The No. 2 flow tank and the No. 1 flow tank are connected to fix the inner layer of the multi-layer hose and the elastic bridge structure together.

[0023] S3: The hose formed in the first forming mechanism is connected to the third flow tank in the second forming mechanism through the placement tank. The material is cooled in the third flow tank to form the outer hose of the multi-layer hose, and the outer hose is fixedly connected to the elastic bridge structure.

[0024] S4: The rollers are driven to rotate by motor No. 3, causing the conveyor belts mounted on the two rollers to rotate in the direction of the rollers' rotation. Since the two conveyor belts are at different layer heights, the processed multi-layer hoses are transported according to the preset length. The hoses are driven to rotate by motor No. 4, causing the processed hoses to be neatly wound on the hose reel.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. Through the No. 1 and No. 2 forming mechanisms, the molten material is cooled in the No. 1 flow tank to form the inner layer of the multi-layer hose, and cooled in the No. 2 flow tank to form an elastic bridge structure. The No. 2 flow tank is connected to the No. 1 flow tank, so that the inner layer of the multi-layer hose and the elastic bridge structure are fixedly connected. In the No. 2 forming mechanism, the material is cooled in the No. 3 flow tank through the placement tank to form the outer layer of the multi-layer hose, so that the outer layer of the hose and the elastic bridge structure are fixedly connected. This process creates an elastic bridge structure between the outer and inner layers of hose, reducing the number of processing steps, shortening the processing time, and thus improving production efficiency.

[0027] 2. By using several No. 2 sliding plates, each with several protrusions that abut against the core, the inner hose is simultaneously formed with several small holes evenly distributed along the hose axis during molding. This reduces the need for drilling holes in the inner hose after it has been manufactured, thus shortening processing time and improving production efficiency.

[0028] 3. The hose is precisely pulled according to the preset length parameters by the traction mechanism to realize the delivery of the hose. Then, the processed hose is neatly wound on the reel by the hose winding mechanism to realize the automation of multi-layer hose processing, thereby reducing labor costs. Attached Figure Description

[0041] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example: Figure 1 As shown, the present invention provides a technical solution: a multi-layer hose processing device. The processing device includes a support base 1, a conveying mechanism 2, a first forming mechanism 3, a second forming mechanism 4, a traction mechanism 5, a hose winding mechanism 6, and a cooling box 7. The support base 1 and the conveying mechanism 2 are fixedly connected, the conveying mechanism 2 and the first forming mechanism 3 are fixedly connected, the first forming mechanism 3 and the second forming mechanism 4 are fixedly connected, the conveying mechanism 2, the first forming mechanism 3, the second forming mechanism 4, the traction mechanism 5 and the hose winding mechanism 6 are arranged sequentially along the processing direction, and the cooling box 7 is fixedly connected to the support base 1.

[0043] The support base 1 supports the conveying mechanism 2, the first forming mechanism 3, and the second forming mechanism 4. The conveying mechanism 2 transports the material for forming the hose into the first forming mechanism 3, where the hose material is cooled. The cooling box 7 accelerates the cooling of the hose material, causing it to change from a liquid to a solid state, forming the inner tube and elastic bridge structure of the multi-layer hose. The conveying mechanism 2 continues to transport the liquid material, pushing the initially formed hose into the second forming mechanism 4. Some of the liquid material flows into the second forming mechanism 4 along with the initially formed hose. This liquid material is cooled to form the outer tube of the multi-layer hose, thus forming a multi-layer hose. The cooling box 7 further cools the multi-layer hose to prevent deformation. The traction mechanism 5 precisely pulls the hose according to preset length parameters, thus achieving hose transport. The winding mechanism 6 neatly winds the processed hose onto a reel.

[0044] like Figures 2-7 As shown, the first forming mechanism 3 includes a fixed rod 31, a core 32, a first mold 33, a first slide plate 34, a second slide plate 35, and a control unit 36. The fixed rod 31 is fixedly connected to the first mold 33, the fixed rod 31 is fixedly connected to the core 32, and the first mold 33 is fixedly connected to the conveying mechanism 2. The first mold 33 is provided with several first sliding grooves 331, and several first slide plates 34 are provided, each of which is slidably connected to several first sliding grooves 331. The control unit 36 ​​is fixedly connected to the first mold 33, and the first mold 33 is provided with several second sliding grooves 332. The system has several second-plate slides 35, which are slidably connected to several second-sliding grooves 332. The system has several control units 36, which are fixedly connected to several first-plate slides 34 and several control units 36 respectively. The system also has several second-plate slides 35 and several control units 36 respectively. The first tube mold 33 has a first-flow groove 333, and the first slide 34 has a second-flow groove 341. The second-flow groove 341 is arc-shaped, and the first-flow groove 333 and the second-flow groove 341 are connected. The second slide 35 has several protrusions 351, which abut against the tube core 32.

[0045] The tube core 32 is fixed by fixing one end of the fixing rod 31 to the first tube mold 33 and the other end to the tube core 32. The first tube mold 33 is provided with a first flow groove 333, and the first slide plate 34 is provided with a second flow groove 341. The material for processing multi-layer hoses flows from the conveying mechanism 2 into the first flow groove 333 and the second flow groove 341. The second flow groove 341 is arc-shaped, so that the processing material of the multi-layer hose forms an arc-shaped elastic bridge structure in the second flow groove 341. By providing several first slide plates 34, the elastic bridges are distributed along the hose axis. The processing material of the multi-layer hose is cooled in the first flow groove 333. The inner layer of the multi-layered hose is formed by several second slide plates 35 with several protrusions 351. The protrusions 351 abut against the core 32, forming several small holes through the inner layer of the hose along the hose axis. The inner layer of the multi-layered hose is fixedly connected to the elastic bridge structure through the second flow groove 341 and the first flow groove 333. The control unit 36 ​​causes the first slide plate 34 to slide into the first sliding groove 331 and the second slide plate 35 to slide into the second sliding groove 332. The conveying mechanism 2 continues to convey the processing material, so that the initially formed multi-layered hose is pushed to the second forming mechanism 4.

[0046] like Figure 2 and Figures 8-11 As shown, the second forming mechanism 4 includes a second tube mold 41, a first outer shell 42, a third sliding plate 43, a spring 44, a baffle 45, a connecting block 46, a fixing block 47, a first motor 48, and a first rotating shaft 49. The second tube mold 41 and the first tube mold 33 are fixedly connected. The second tube mold 41 is provided with a placement groove 411. The first outer shell 42 and the first tube mold 33 are fixedly connected. The second tube mold 41 is provided with a third sliding groove 412. The third sliding plate 43 and the third sliding groove 412 are slidably connected. The spring 44 is set in the third sliding groove 412. The spring 44 and the third sliding plate 43 are fixedly connected. The fixing block 47 and the first outer shell 42 are fixedly connected. The first motor 48 and the fixing block 47 are fixedly connected. The output end of the first motor 48 is fixedly connected to the first rotating shaft 49. The first rotating shaft 49 and the connecting block 46 are connected in a transmission manner. The baffle 45 and the connecting block 46 are fixedly connected. The first outer shell 42 is provided with a third flow groove 421.

[0047] The pre-formed multi-layered hose is pushed into the placement groove 411 by the conveying mechanism 2 when the processing material is conveyed. The material flows into the third flow groove 421 between the first outer shell 42 and the second tube mold 41. The material cools in the flow groove to form the outer layer of the multi-layered hose. The outer layer of the hose is connected to the third flow groove 421 through the placement groove 411 and the third flow groove 421, so that the outer layer of the hose and the elastic bridge structure are fixedly connected. This forms several relatively independent but connected channels between the outer and inner hoses. The first motor 48 is fixed by the fixing block 47, and the first motor 48 outputs... The end is connected to the first rotating shaft 49. The first motor 48 drives the first rotating shaft 49 to rotate, causing the baffle 45 to flip, thereby connecting the placement groove 411 and the third flow groove 421 to the outside. The processing material is continued to be conveyed through the conveying mechanism 2, so that the multi-layer hose is pushed. The third slide plate 43 slides into the third sliding groove 412, pushing the multi-layer hose to the outside of the second forming mechanism 4. The initially formed multi-layer hose is then pushed to the placement groove 411. The third slide plate 43 is reset under the action of the spring 44, and the processing material continues to flow into the third flow groove 421, thereby continuously generating multi-layer hose.

[0048] like Figure 6 and Figure 7 As shown, the control unit 36 ​​includes an electric cylinder 361, a first connecting rod 362, a second connecting rod 363, a third connecting rod 364, a fourth connecting rod 365, and a fifth connecting rod 366. The electric cylinder 361 is fixedly connected to the first tube mold 33, and the output end of the electric cylinder 361 is fixedly connected to the first connecting rod 362. The first tube mold 33 is provided with a fourth sliding groove 334, and the first connecting rod 362 is slidably connected to the fourth sliding groove 334. The first tube mold 33 is provided with a fifth sliding groove 335, and the second connecting rod 363 is connected to the fifth sliding groove 335. The components are connected in a sliding manner: connecting rod 363 is fixedly connected to connecting rod 362; connecting rod 364 is slidably connected to sliding groove 335; connecting rod 364 is fixedly connected to connecting rod 363; connecting rod 364 is fixedly connected to sliding plate 34; connecting rod 365 is fixedly connected to connecting rod 362; connecting rod 366 is slidably connected to connecting rod 365; and the first tube mold 33 is provided with sliding groove 336, which is slidably connected to connecting rod 365.

[0049] The electric cylinder 361 is fixed to the outside of the first tube mold 33, thus fixing the entire control unit 36 ​​to the first tube mold 33. The output end of the electric cylinder 361 is fixedly connected to the first connecting rod 362. The output end of the electric cylinder 361 extends, driving the first connecting rod 362 to slide in the fourth sliding groove 334 along the processing direction. The first connecting rod 362 is fixedly connected to the second connecting rod 363, causing the second connecting rod 363 to move with the first connecting rod 362. The conveying mechanism 2 conveys materials to push the initially formed multi-layer hose, causing the first sliding plate 34 to slide into the first sliding groove 331, and the third... Connecting rod 364 and slide plate 34 are fixedly connected, allowing connecting rod 364 to slide into slide groove 335. Connecting rod 365 and connecting rod 362 are fixedly connected, allowing slide plate 35 to slide into slide groove 332. This causes the initially formed multi-layer hose to be pushed by the processing material along the processing method. The output end of electric cylinder 361 retracts, causing connecting rods 362, 363, 364, 365, and 366 to reset, thus continuing to form the initially formed multi-layer hose in mold 33.

[0050] like Figure 2 and Figure 3 As shown, the conveying mechanism 2 includes a second housing 21, a second motor 22, a second rotating shaft 23, a spiral blade 24, and a heating tube 25. The second housing 21 is fixedly connected to the support base 1, the second motor 22 is fixedly connected to the support base 1, the output end of the second motor 22 is fixedly connected to the second rotating shaft 23, the spiral blade 24 is fixedly connected to the second rotating shaft 23, the second housing 21 is provided with a mounting groove 211, and the heating tube 25 is placed in the mounting groove 211.

[0051] The conveying mechanism 2 is fixed by the second outer shell 21 and the support base 1. The second motor 22 drives the second rotating shaft 23 to rotate, which in turn rotates the spiral blade 24 fixedly connected to the second rotating shaft 23, thereby moving the processed material along the processing direction. The second outer shell 21 is provided with an installation groove 211, and a heating tube 25 is installed in the installation groove 211, so that the processed material melts from solid to liquid during the movement and is then transported into the first tube mold 33.

[0052] like Figure 1 and Figure 2 As shown, the traction mechanism 5 includes a third motor 51, a first fixed plate 52, rollers 53, and a conveyor belt 54. The third motor 51 and the first fixed plate 52 are fixedly connected. There are two first fixed plates 52. There are four rollers 53. The two first fixed plates 52 and the four rollers 53 are rotatably connected. The output end of the third motor 51 is fixedly connected to one of the rollers 53. There are two conveyor belts 54. The two conveyor belts 54 are located at different layer heights. The conveyor belts 54 are sleeved on the two rollers 53.

[0053] Two fixed plates 52 and rollers 53 are rotatably connected and fixed from both ends of the rollers 53. The output end of motor 51 is connected to one of the rollers 53, so that motor 51 drives roller 53 to rotate. This causes the conveyor belt 54 sleeved on the two rollers 53 to rotate in the direction of rotation of the rollers 53. Since the two conveyor belts 54 are located at different layer heights, the processed multi-layer hose is transported according to the preset length.

[0054] like Figure 1 As shown, the tube winding mechanism 6 includes a fourth motor 61, a tube winding shaft 62, and a second fixing plate 63. There are two second fixing plates 63. The tube winding shaft 62 is rotatably connected to the two second fixing plates 63. The fourth motor 61 is fixedly connected to the second fixing plate 63. The output end of the fourth motor 61 is fixedly connected to the tube winding shaft 62.

[0055] The hose reel 62 is rotatably connected to two No. 2 fixing plates 63, so that both ends of the hose reel 62 are fixed and can rotate along its own axis. The No. 4 motor 61 fixed on one of the No. 2 fixing plates 63 drives the hose reel 62 to rotate along its own axis, so that the processed hose is neatly wound on the hose reel 62.

[0056] A processing method for a multi-layer hose processing device includes the following steps:

[0057] S1: The second rotating shaft 23 is driven to rotate by the second motor 22, which in turn rotates the spiral blade 24, thereby moving the processed material along the processing direction. During the movement of the processed material, the heating tube 25 installed causes the processed material to melt from solid to liquid.

[0058] S2: The molten material is cooled in the first flow tank 333 to form the inner layer of the multi-layer hose. Through the protrusion 351 provided in the second slide plate 35, several small holes are formed in the inner layer hose along the hose axis. The material is cooled in the second flow tank 341 to form an elastic bridge structure. The second flow tank 341 and the first flow tank 333 are connected to fix the inner layer of the multi-layer hose and the elastic bridge structure together.

[0059] S3: The hose formed in the first forming mechanism 3 is connected to the third flow channel 421 through the placement channel 411 in the second forming mechanism 4. The material is cooled in the third flow channel 421 to form the outer hose of the multi-layer hose, and the outer hose is fixedly connected to the elastic bridge structure.

[0060] S4: The roller 53 is driven to rotate by motor 51, so that the conveyor belt 54 sleeved on the two rollers 53 rotates in the direction of rotation of the rollers 53. The two conveyor belts 54 are located at different layer heights, so that the processed multi-layer hose is transported according to the preset length. The coiling shaft 62 is driven to rotate by motor 61, so that the processed hose is neatly wound on the coiling shaft 62.

[0061] Working principle: The material to be processed is poured into the second housing 21 of the conveying mechanism 2. The second motor 22 drives the second rotating shaft 23 to rotate, causing the spiral blades 24 to rotate, thereby moving the material along the processing direction. Through the installed heating tubes 25, the material is melted from solid to liquid during the movement. The molten material flows into the first flow channel 333 and the second flow channel 341. The second flow channel 341 is arc-shaped, so that the material of the multi-layer hose forms an arc-shaped elastic bridge structure in the second flow channel 341. Several first slide plates 34 are provided to distribute the elastic bridge along the hose axis. Several second slide plates 35 are provided with several protrusions 351, which abut against the tube core 32. The material of the multi-layer hose is cooled in the first flow channel 333 to form an inner hose with small holes. Through the second flow channel 341 and the first flow channel 341, the material is transferred to the second flow channel 341. The flow channel 333 is connected, so that the inner layer of the multi-layer hose and the elastic bridge structure are fixedly connected. Through the control unit 36, the first slide plate 34 and the second slide plate 35 are loosened from the initially formed hose. The processing material pushes the initially formed multi-layer hose to the placement channel 411. The processing material flows into the third flow channel 421. The placement channel 411 and the third flow channel 421 are connected. The material is cooled in the third flow channel 421 to form the outer layer of the multi-layer hose. The outer layer hose and the elastic bridge structure are fixedly connected. The third motor 51 drives the roller 53 to rotate, so that the conveyor belt 54 sleeved on the two rollers 53 rotates in the direction of rotation of the rollers 53. The two conveyor belts 54 are located at different layer heights, so that the processed multi-layer hose is pulled according to the preset length. The fourth motor 61 drives the winding shaft 62 to rotate, so that the processed hose is neatly wound on the winding shaft 62.
