Description

Technical Field

[0001] This utility model relates to the field of hose processing equipment, and more specifically, to a glue-applying device for hose processing. Background Technology

[0002] Fire hoses mainly consist of an outer braided hose layer and an inner TPU lining hose layer. To improve the bonding strength between the two layers, one method is to inject high-temperature steam into the TPU lining hose, causing it to melt and bond to the inner wall of the outer braided hose layer. Another method is to apply adhesive to the outer wall of the TPU lining hose, then insert it into the outer braided hose layer, inflate it with air to make it expand, and then adhere it to the inner wall of the outer braided hose layer. For the second method, during production, tools are needed to apply adhesive to the outer wall of the TPU lining hose. Currently, most methods involve manual application using a handheld brush, which is not only labor-intensive and increases manufacturing costs, but also inconvenient and inefficient. Therefore, we propose a hose application device to solve these problems. Utility Model Content

Through an L-shaped bracket and a support tube assembly, the two ends of the outer braided hose can be directly supported by arc-shaped support rings and then stretched taut during glue application. One end of the TPU-lined hose can pass through two through slots inside a support tube assembly into the outer braided hose, and is pulled out from the other end of the outer braided hose by a traction rope. Glue-applying rollers are installed on both through slots of the TPU-lined hose, contacting and adhering to the surface of the TPU-lined hose. This allows the TPU-lined hose to rotate when pulled, thereby evenly applying the glue stored in the storage box onto the surface of the TPU-lined hose. The device is simple to operate, provides good glue application continuity, avoids manual application, and greatly improves the efficiency of glue application.

[0007] A glue-applying device for hose processing includes a set of L-shaped supports and a set of support tube assemblies. The L-shaped supports and the support tube assemblies are structurally identical and arranged in opposite directions. The support tube assembly includes an upper adjusting plate and a lower adjusting plate. The bottom of the lower adjusting plate is fixedly welded to the top of the L-shaped supports. A set of shaft holes is provided on the lower adjusting plate. A threaded shaft is rotatably connected to each of the shaft holes through bearings. A handwheel is fixedly installed at the bottom of the threaded shaft. An external thread structure is provided on the outer wall of the top of the threaded shaft. An internal thread through hole is provided on the upper adjusting plate corresponding to the position of the threaded shaft. The top of the threaded shaft is threadedly connected to the internal thread through hole.

[0008] Both the upper and lower adjusting plates have arc-shaped support rings fixedly welded to one side. The arc-shaped support rings on a set of support pipe assemblies are connected by an outer braided water hose. A through groove is opened at the connection between the upper and lower adjusting plates. A TPU inner lining water hose is set inside the corresponding two through grooves. One end of the TPU inner lining water hose extends through the through groove into the outer braided water hose.

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example 1:

[0024] Please see Figures 1-4A gluing device for water hose processing includes a set of L-shaped brackets 1 and a set of support tube assemblies 2. The L-shaped brackets 1 and the support tube assemblies 2 have the same structure and are arranged in opposite directions. The support tube assembly 2 includes an upper adjusting plate 201 and a lower adjusting plate 202. The bottom of the lower adjusting plate 202 is fixedly welded to the top of the L-shaped bracket 1. A set of shaft holes are opened on the lower adjusting plate 202. A threaded shaft 203 is rotatably connected to the inside of the set of shaft holes through bearings. A handwheel 204 is fixedly installed at the bottom of the threaded shaft 203. An external thread structure is opened on the outer wall of the top of the threaded shaft 203. An internal thread through hole is opened on the upper adjusting plate 201 at the position corresponding to the threaded shaft 203. The top of the threaded shaft 203 is threadedly connected to the internal thread through hole.

[0025] Arc-shaped support rings 205 are fixedly welded to one side of the upper adjustment plate 201 and the lower adjustment plate 202. The arc-shaped support rings 205 on a set of support pipe assemblies 2 are connected by the outer braided water hose 3. A through groove 206 is opened at the connection between the upper adjustment plate 201 and the lower adjustment plate 202. A TPU inner lining water hose 4 is set inside the two through grooves 206. One end of the TPU inner lining water hose 4 extends through the through groove 206 into the outer braided water hose 3. One end of the TPU inner lining water hose 4 located inside the outer braided water hose 3 is tied with a traction rope 5. One end of the traction rope 5 extends to the outside through the other end of the outer braided water hose 3.

[0026] An opening 6 is provided on the upper adjustment plate 201 and the lower adjustment plate 202 located on one side of the TPU inner lining water strip 4. The opening 6 is connected to the inside of the corresponding through groove 206. A glue-applying roller 7 is rotatably connected inside the opening 6. The roller surfaces of the two glue-applying rollers 7 are in contact with the top and bottom of the TPU inner lining water strip 4, respectively. A storage box 8 is fixedly installed on the top of the upper adjustment plate 201 and the bottom of the lower adjustment plate 202 at the corresponding opening 6. The storage box 8 stores glue inside, and a glue-injecting nozzle 801 is fixedly installed on one side of the storage box 8.

[0027] The working principle of this type of adhesive coating device for water hose processing is as follows:

[0028] First, fill both storage boxes 8 with glue through the glue injection nozzle 801. Then, attach both ends of the outer braided water hose 3 to the two arc-shaped support rings 205 of a set of support tube assemblies 2, achieving the effect of supporting both ends of the outer braided water hose 3 from the inside. Then, pass a traction rope 5 through the through groove 206 on the set of support tube assemblies 2 and through the inside of the outer braided water hose 3, and tie one end of the traction rope 5 to one end of the TPU inner lining water hose 4. At this time, you can pull from the other end of the traction rope 5 to make one end of the TPU inner lining water hose 4 move into the outer braided water hose 3 through the corresponding two through grooves 206. When the TPU inner lining... When one end of the water belt 4 reaches the position of the two glue-applying rollers 7, it can also drive the glue-applying rollers 7 to rotate while adhering, so that the TPU inner water belt 4 moves forward and applies the glue inside the storage box 8 to the outer surface of the TPU inner water belt 4 through the glue-applying rollers 7. This continues until one end of the TPU inner water belt 4 reaches the other end of the outer braided water belt 3 as the traction rope 5 pulls it. At this point, the TPU inner water belt 4 near the storage box 8 can be cut off, and air can be injected into the TPU inner water belt 4 through the air-inflating device to make it expand. Then, the outer wall of the TPU inner water belt 4 is firmly attached to the inside of the outer braided water belt 3 with glue.

[0029] Example 2:

[0030] In view of the above embodiment 1, further description is provided, see reference Figure 2 and Figure 4 The length and width of the coating roller 7 are equal to the length and width of the opening 6. The roller surfaces of the two coating rollers 7 do not contact each other. The crossbars at the bottom of a set of L-shaped brackets 1 are interlocked, and the interlocking points of the crossbars at the bottom of a set of L-shaped brackets 1 are fixedly installed by bolts.

[0031] The crossbars at the bottom of a set of L-shaped brackets 1 are interlocked, and the interlocking points of the crossbars at the bottom of the set of L-shaped brackets 1 are fixed with bolts. This allows the distance between the L-shaped brackets 1 to be adjusted to meet the support requirements of different lengths of braided water hoses 3. The upper adjusting plate 201 and the lower adjusting plate 202 are connected by a threaded shaft 203. When the handwheel 204 is turned, the threaded shaft 203 is rotated, thereby adjusting the distance between the upper adjusting plate 201 and the lower adjusting plate, as well as the distance between the two arc-shaped support rings 205 at the corresponding positions, to meet the support requirements of different diameters of braided water hoses 3. By ensuring that the length and width of the glue-applying roller 7 are equal to the length and width of the opening 6, gaps can be reduced and the risk of glue dripping can be lowered.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
