Description

Technical Field

[0001] This invention relates to the field of nuclear power hose processing and manufacturing technology, and in particular to a double-letter correction device for soft-core hoses. Background Technology

[0002] The flexible core method for producing flexible hoses uses a flexible core as the inner mold for hose forming. During the hose forming process, the flexible core provides internal support and is extracted, dissolved, or melted out from the formed hose. The main steps are as follows: Step 1: Using an inner rubber extruder, the uncured inner rubber layer is evenly coated onto the surface of the soft core to form the inner rubber layer. Step 2: Using a middle rubber extruder, the uncured middle rubber layer is evenly coated onto the inner rubber layer to form the middle rubber layer. Step 3: Using an outer rubber extruder, the uncured outer rubber layer is evenly coated onto the middle rubber layer to form the outer rubber layer; the inner rubber layer, middle rubber layer, and outer rubber layer together form a long strip-shaped tube blank; Step 4: The long strip of tube blank, together with the soft core, is wound up using a winding device; during the winding process, the tube blank passes through the winding rollers and is wound into a spiral shape. Step 5: Move the tube blank forward in a straight line through the water-coated cloth winding machine, which will wrap the water-coated cloth around the tube blank. Step 6: The tube blank wrapped with water-repellent cloth, together with the soft core, is fed into the vulcanization equipment. The tube blank is vulcanized and formed into a flexible hose in the vulcanization equipment. Step 7: The soft core is extracted, dissolved, or melted out from the formed hose using a core removal device, thus completing hose production.

[0003] Affixing and engraving lettering strips are crucial steps in the production of hose product identification. In the flexible core method of hose manufacturing, affixing lettering strips typically occurs between steps three and four, while engraving lettering strips generally occurs between steps four and five, with the strips facing each other. The flexible core method of hose manufacturing cannot reliably affix and engrave lettering strips because: After the label is affixed, the long tube blank needs to be wound up. During the winding process, the tube blank will pass through the winding roller and be wound into a spiral shape. The label that was affixed to a certain position in the tube blank beforehand will become random and unpredictable in its specific angular position in the circumferential direction of the tube blank after winding. Since the placement of the lettering strips is completely random after winding, when the billet is unwound again to engrave the lettering strips, the operator cannot know the exact angle and position of the previously attached lettering strips. Therefore, it is impossible to precisely engrave the lettering strips in the exact position opposite to the attached lettering strips. Worse still, because the placement of the lettering is random, it could very well be at or very close to the location where the operator planned to engrave the lettering; if the lettering is engraved directly in the area where the lettering is to be attached, it could damage the lettering or cause the two types of lettering to overlap and intersect, affecting the appearance and readability of the hose product markings. Summary of the Invention

[0004] The purpose of this invention is to provide a double-letter correction device for flexible core tubing, ensuring that the positions of the lettering strips and the engraved lettering strips are correctly aligned in flexible core tubing production, thereby enabling reliable lettering and engraving of flexible core tubing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A flexible tube double-line correction device includes a frame, two line-mounting assemblies, a guide assembly, a support assembly, and a line sleeve. An upper support frame and a lower support frame are fixedly connected to the top and bottom of one end of the frame, respectively. A bearing rod is fixedly connected to the end of each of the upper and lower support frames away from the frame, and a positioning assembly is fitted to one end of each bearing rod. The two line-mounting assemblies are connected to the two bearing rods via the positioning assembly and are used to receive the flexible tube and carry the line. The guide assembly is fitted in the middle of the frame and is used to receive and guide the flexible tube. The support assembly is fitted at one end of the frame and is used to maintain the path of the flexible tube. An end cap is fixedly connected to one end of the line sleeve, and both ends of the end cap have movable slots. A guide groove corresponding to the movable slots is formed on the outer side of the line sleeve.

[0006] As one possible implementation, the letter mounting assembly includes a mounting shaft for receiving a flexible tube; two opposing winding roller bodies are rotatably connected to the outer side of the mounting shaft, one winding roller body for mounting a letter for attaching a letter, and the other winding roller body for mounting a letter for engraving a letter; slots are symmetrically opened on both sides of one end of the mounting shaft, and a locking hole is opened in the middle of one end of the mounting shaft.

[0007] As one possible approach, both the movable slot and the guide slot are arc-shaped, and multiple through holes are provided on the outer side of the end cap. Through the structural characteristics of the movable slot and the guide slot, the lettering strips at the main body of the winding roller can be effectively guided to prevent the lettering strips from deviating, and the position of the engraved lettering strips can be adjusted according to the position of the lettering strips. The presence of through holes allows the end caps to be installed on the outer rubber extrusion equipment or winding equipment of the hose with the help of connectors.

[0008] In one possible implementation, the positioning assembly includes an assembly plate and two linkage rods. The assembly plate is fixedly connected to one end of a support rod, and a mounting shaft is inserted into the assembly plate. Extension frames are fixedly connected to both sides of the assembly plate, and positioning shafts are slidably connected to the middle of each of the two extension frames. A positioning arc plate is fixedly connected to one end of each of the two positioning shafts, and a helical spring is sleeved on the positioning shaft between the positioning arc plate and the extension frame. The linkage rod is rotatably connected to the end of the positioning shaft away from the extension frame, and a guide plate is rotatably connected to the outer side of the assembly plate. The ends of the two linkage rods away from the positioning shaft are rotatably connected to the two ends of the guide plate, respectively.

[0009] As one possible approach, a plug is fixedly connected to the middle of one side of the assembly plate, and the plug is inserted into the locking hole. By setting the plug, before the mounting shaft is assembled with the assembly plate, the mounting shaft is sleeved on the outside of the plug through the locking hole to achieve initial support for the mounting shaft.

[0010] One possible approach is to fix a limiting strip to the insertion rod, and set a limiting groove inside the locking hole. The limiting strip is slidably connected inside the limiting groove. Through the structural cooperation between the limiting strip and the limiting groove, the rotation of the mounting shaft is restricted when the limiting strip moves into the limiting groove. After the mounting shaft contacts the assembly plate, the extension frame will correspond to the slot, avoiding repeated adjustments later.

[0011] One possible implementation involves a non-slip pad fixedly connected to the inner side of the positioning arc plate, with non-slip textures on the outer side of the non-slip pad. A locking rod is located in the middle of the inner side of the positioning arc plate, engaging with the inside of the slot. The non-slip pad increases the friction between the positioning arc plate and the surface of the mounting shaft, and the locking rod engages with the mounting shaft when they come into contact, further locking the mounting shaft and ensuring its stability.

[0012] As one possible implementation, the guide assembly includes a guide frame; the guide frame is fixedly connected to the middle of the frame, and a guide groove is opened in the middle of the guide frame. The bottom end and the middle part of the guide groove are respectively movably connected to a lower guide shaft and an upper guide shaft. A guide roller is rotatably connected to the outer side of the lower guide shaft, and a guide disc is rotatably connected to one end of the upper guide shaft.

[0013] One possible implementation is that the support assembly includes a carrier plate and two locking rods. The carrier plate is fixedly connected to one end of the frame, and a stabilizing support roller is rotatably connected to the top of the carrier plate. A stabilizing through groove is opened on the bottom of the carrier plate away from the stabilizing support roller. Two support shafts are movably connected inside the stabilizing through groove, and side support rollers are movably connected to the outer sides of the two support shafts. One locking rod is fixedly connected to the bottom end of the carrier plate, and the other locking rod is fixedly connected to the inner side of the guide frame. One end of the lower guide shaft, the upper guide shaft, and the support shaft is fixedly connected to a positioning component. The positioning component cooperates with the locking rod to lock the position of the lower guide shaft, the upper guide shaft, and the support shaft.

[0014] As one possible implementation, the positioning component includes a locking ring and a positioning screw; one side of the locking ring has an opening, and two extension plates are fixedly connected to the opening, one of which has a threaded hole in the middle and the other extension plate has a clearance hole in the middle; the positioning screw is threaded into the threaded hole, and one end of the positioning screw passes through the clearance hole and is fixedly connected to a baffle.

[0015] As one possible approach, the diameter of the clearance hole is smaller than the diameter of the baffle. By changing the size of the clearance hole and the baffle, the baffle is pressed against the extension plate at the clearance hole as it moves with the clearance hole, thereby reducing the distance between the two extension plates and causing the locking ring to grip the locking rod tightly.

[0016] Beneficial technical effects of the present invention: The flexible tube double-letter correction device of the present invention, through the arrangement of end caps, movable slots, guide slots and two winding roller bodies, can effectively correct the engraved lettering from the opposite direction of the two lettering, thus effectively solving the problem of lettering position misalignment; through the combined assembly of positioning components and mounting shafts, the winding roller body can be quickly replaced after the lettering at the winding roller body is consumed, greatly improving the overall convenience; through the structural cooperation of the guide components and support components, the path of the flexible tube can be assisted and supported during the flexible tube transmission process, ensuring the effect of lettering adhesion.

[0025] See Figure 1-8 This invention provides a flexible tube double-letter correction device, comprising a frame 1, two letter-mounting assemblies 6, a guide assembly 7, a support assembly 8, and a letter-mounting sleeve 9; an upper support frame 2 and a lower support frame 3 are fixedly connected to the top and bottom of one end of the frame 1, respectively, and a bearing rod 4 is fixedly connected to the end of the upper support frame 2 and the lower support frame 3 away from the frame 1, and a positioning assembly 5 is assembled at one end of the bearing rod 4; the two letter-mounting assemblies 6 are connected to the two bearing rods 4 through the positioning assembly 5, and are used to receive the flexible tube and carry the letter; the guide assembly 7 is assembled in the middle of the frame 1, and is used to receive the flexible tube and guide it; the support assembly 8 is assembled at one end of the frame 1, and is used to maintain the path of the flexible tube; an end cap 10 is fixedly connected to one end of the letter-mounting sleeve 9, and both ends of the end cap 10 are provided with movable slots 11, and the outer side of the letter-mounting sleeve 9 is provided with a guide groove 12 that is adapted to the movable slots 11.

[0026] In this embodiment, as one possible implementation method, the letter mounting assembly 6 includes a mounting shaft 13 for receiving a flexible tube; two oppositely arranged winding roller bodies 14 are rotatably connected to the outer side of the mounting shaft 13, one winding roller body 14 is used to mount the lettering strip, and the other winding roller body 14 is used to mount the engraved lettering strip; slots 15 are symmetrically opened on both sides of one end of the mounting shaft 13, and a locking hole 16 is opened in the middle of one end of the mounting shaft 13.

[0027] In this embodiment, as one possible implementation method, both the movable slot 11 and the guide slot 12 are arc-shaped, and multiple through holes are provided on the outer side of the end cap 10. Through the structural characteristics of the movable slot 11 and the guide slot 12, the letter strip at the winding roller body 14 can be effectively guided to avoid the letter strip from deviating, and the position of the engraved letter strip can be adjusted according to the position of the letter strip. The presence of through holes allows the end cap 10 to be installed on the outer rubber extrusion equipment of the hose with the help of connectors.

[0028] In this embodiment, as one possible implementation, the positioning component 5 includes an assembly plate 17 and two linkage rods 22. The assembly plate 17 is fixedly connected to one end of the bearing rod 4, and the mounting shaft 13 is inserted into the assembly plate 17. Extension frames 18 are fixedly connected to both sides of the assembly plate 17. Positioning shafts 19 are slidably connected to the middle of the two extension frames 18. Positioning arc plates 20 are fixedly connected to one end of the two positioning shafts 19. A helical spring 21 is sleeved on the positioning shaft 19 between the positioning arc plate 20 and the extension frame 18. The linkage rods 22 are rotatably connected to the end of the positioning shaft 19 away from the extension frame 18. A guide plate 23 is rotatably connected to the outer side of the assembly plate 17. The ends of the two linkage rods 22 away from the positioning shaft 19 are rotatably connected to the two ends of the guide plate 23, respectively.

[0029] In this embodiment, as one possible approach, a plug is fixedly connected to the middle of one side of the assembly plate 17, and the plug is inserted into the locking hole 16. By setting the plug, before assembling the mounting shaft 13 with the assembly plate 17, the mounting shaft 13 is first sleeved on the outside of the plug through the locking hole 16, which can provide initial support for the mounting shaft 13.

[0030] In this embodiment, as one possible approach, a limiting strip is fixedly connected to the insertion rod, and a limiting groove is provided inside the locking hole 16. The limiting strip is slidably connected inside the limiting groove. Through the structural cooperation between the limiting strip and the limiting groove, the rotation of the mounting shaft 13 can be restricted when the limiting strip moves into the limiting groove. After the mounting shaft 13 contacts the assembly plate 17, the extension frame 18 will correspond to the slot 15, avoiding repeated adjustments later.

[0031] In this embodiment, as one possible implementation method, an anti-slip pad is fixedly connected to the inner side of the positioning arc plate 20, and anti-slip texture is provided on the outer side of the anti-slip pad; a locking rod is provided in the middle of the inner side of the positioning arc plate 20, and the locking rod is engaged with the inside of the slot 15; by setting the anti-slip pad, the friction between the positioning arc plate 20 and the surface of the mounting shaft 13 can be increased, and with the setting of the locking rod, when the positioning arc plate 20 and the surface of the mounting shaft 13 are in contact, the locking rod can be engaged with the inside of the slot 15, thereby further locking the mounting shaft 13 and ensuring the stability of the application of the mounting shaft 13.

[0032] In this embodiment, as one possible implementation, the guide assembly 7 includes a guide frame 24; the guide frame 24 is fixedly connected to the middle of the frame 1, and a guide groove 25 is provided in the middle of the guide frame 24. The bottom end and the middle part of the guide groove 25 are respectively movably connected to a lower guide shaft 26 and an upper guide shaft 27. A guide roller 28 is rotatably connected to the outer side of the lower guide shaft 26, and a guide disc 29 is rotatably connected to one end of the upper guide shaft 27.

[0033] In this embodiment, as one possible implementation, the support assembly 8 includes a bearing plate 30 and two locking light rods 35. The bearing plate 30 is fixedly connected to one end of the frame 1. A stabilizing support roller 31 is rotatably connected to the top of the bearing plate 30. A stabilizing through groove 32 is opened on the bottom side of the bearing plate 30 away from the stabilizing support roller 31. Two support shafts 33 are movably connected inside the stabilizing through groove 32. Side support rollers 34 are movably connected to the outer sides of the two support shafts 33. One locking light rod 35 is fixedly connected to the bottom end of the bearing plate 30, and the other locking light rod 35 is fixedly connected to the inner side of the guide frame 24. One end of the lower guide shaft 26, the upper guide shaft 27, and the support shaft 33 are all fixedly connected to a positioning member 36. The positioning member 36 cooperates with the locking light rod 35 to lock the position of the lower guide shaft 26, the upper guide shaft 27, and the support shaft 33.

[0034] In this embodiment, as one possible implementation method, the positioning member 36 includes a locking ring 37 and a positioning screw 41; an opening 38 is provided on one side of the locking ring 37, and two extension plates 39 are fixedly connected to the opening 38. One extension plate 39 has a threaded hole in the middle, and the other extension plate 39 has a clearance hole 40 in the middle; the positioning screw 41 is threaded into the threaded hole, and one end of the positioning screw 41 passes through the clearance hole 40 and is fixedly connected to a baffle 42.

[0035] In this embodiment, the diameter of the clearance hole 40 is smaller than the diameter of the baffle 42. By changing the size of the clearance hole 40 and the baffle 42, when the baffle 42 moves with the clearance hole 40, it can squeeze the extension plate 39 at the clearance hole 40, thereby reducing the distance between the two extension plates 39 and causing the locking ring 37 to hold the locking rod 35 tightly.

[0036] The above-mentioned flexible tube double-letter correction device can perform lettering on flexible tubes using the flexible tube method, including the following steps: The frame 1 and end cap 10 are installed on the outer rubber extrusion equipment of the hose using tools; the hose, whose outer rubber layer is extruded on the outer rubber extrusion equipment, enters the interior of the letter sleeve 9; the letter strip for attaching the letter strip is mounted on the winding roller body 14; During the process of attaching labels to the flexible tube, the flexible tube that comes out of the label sleeve 9 can be placed between the guide roller 28 and the guide plate 29, above the stabilizing support roller 31, between the two side support rollers 34, and between the two bearing rods 4. The label at the main body 14 of the winding roller is guided through the movable hole groove 11 and the guide groove 12 to be directly aligned with the flexible tube placed on the bearing rod 4, thereby effectively limiting the path of the flexible tube and preventing the flexible tube from deviating and affecting the labeling effect. Simultaneously, the positioning screw 41 can be rotated to move the baffle 42 away from the clearance hole 40. As the extension plate 39 at the clearance hole 40 loses its compression, the opening 38 returns to its original state, reducing the distance between the locking ring 37 and the locking rod 35. This unlocks the lower guide shaft 26, the upper guide shaft 27, or the support shaft 33. Then, pulling the lower guide shaft 26, the upper guide shaft 27, or the support shaft 33 will cause the lower guide shaft 26, the upper guide shaft 27, and the support shaft 33 to move on the locking rod 35, thereby adjusting the distance between the lower guide shaft 26 and the upper guide shaft 27 and between the two support shafts 33 to accommodate hoses of different specifications. After adjustment, rotating the positioning screw 41 causes the positioning screw 41 to press the extension plate 39 at the clearance hole 40, thereby narrowing the opening 38 and causing the locking ring 37 to grip the locking rod 35. Furthermore, any one of the positioning shafts 19 can be pulled, causing the positioning arc plate 20 to move away from the mounting shaft 13 under the limitation of the extension frame 18. Since the support shaft 33 is connected between the positioning shaft 19 and the guide plate 23, when one of the positioning shafts 19 moves, the guide plate 23 can be pushed by the linkage rod 22, causing the guide plate 23 to rotate under the support of the assembly plate 17. And through another linkage rod 22, the positioning shaft 19 is pushed, causing the two positioning arc plates 20 to move away simultaneously, thereby unlocking the mounting shaft 19. The mounting shaft 13 is then detached from the assembly plate 17 to replace the winding roller body 14. After replacement, the pulling of the positioning shaft 19 is released. As the positioning shaft 19 moves, it can compress the helical spring 21 through the positioning arc plate 20. After the positioning shaft 19 is released, the rebound of the helical spring 21 can cause the positioning arc plate 20 to disengage from the assembled mounting shaft 13, thereby locking the position of the winding roller body 14 and preventing the winding roller body 14 from shaking and affecting the transmission of the text.

[0037] The aforementioned flexible tube double-letter correction device can also perform flexible tube lettering; the transmission path of the flexible tube is the same during the flexible tube lettering process and the flexible tube lettering process; the steps of the flexible tube lettering process are basically the same as those of the flexible tube lettering process, except that the frame 1 and end cap 10 are installed on the flexible tube winding equipment with the help of tools, so that the wound flexible tube enters the inside of the letter sleeve 9, and the lettering strip for lettering is mounted on the winding roller body 14, with the position of the lettering strip being directly opposite the position of the lettering strip.

[0038] In the process of engraving and attaching lettering strips to flexible tubes using the soft-core method, the transmission path of the tube is the same, and the positions of the engraved and attached lettering strips are directly opposite each other, thus achieving double lettering strip alignment in the soft-core method.

[0039] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
