[0047] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0048] See also Figure 1 As shown, this embodiment provides a heading structure, including a bracket 100 and a molding die 200, an extrusion die 300, a rope feeding assembly 400, a rubber feeding assembly 500 and a glue spraying assembly 600, all of which are installed on the bracket 100; the rope feeding assembly 400 is used to transfer the rope 700 to the extrusion die 300, the rubber feeding assembly 500 is used to transfer the rubber to the molding die 200 for molding and then feed it into the extrusion die 300, and the glue spraying assembly 600 is used to spray glue on the rubber in the extrusion die 300; the extrusion die 300 is used to cover the molded rubber on the rope 700.

[0049] When in use, the rope 700 is pulled out from the rope feeding assembly 400 through other rope pulling assemblies or manual rope pulling by the staff, so that the rope 700 is located in the extrusion mold 300, and then the rubber feeding assembly 500 will supply the rubber to the molding mold 200, and the molding mold 200 will mold the rubber to obtain the required shape, and then supply it from the molding mold 200 to the extrusion mold 300, and then the rubber in the extrusion mold 300 will be sprayed with glue through the glue spraying assembly 600, and finally the rope 700 will be wrapped on the rope 700 through the extrusion mold 300 to complete the heading of the rope 700. Through such a setting, the work efficiency is greatly improved, and it is no longer necessary to manually head the ropes 700 one by one.

[0050] Specifically, in actual use, the heading structure is arranged between the rope feeding assembly 400 and the rope taking assembly. Before starting work, the staff will pass the rope 700 on the rope feeding assembly 400 through the heading structure and clamp it on the rope taking assembly. Then the rope taking assembly can pull the rope 700 to move on the heading structure, so that the heading structure can continuously perform heading work on the rope 700.

[0051] Among them, the rope 700 will enter the extrusion mold 300 of the heading structure, and the rubber will be transferred to the molding mold 200 by the rubber feeding assembly 500. The molding mold 200 will cut the rubber and mold the rubber into a set shape, and then the molded rubber will be transferred to the extrusion mold 300, and the rubber will be wrapped around the rope 700 through the extrusion mold 300 to complete the heading work.

[0052] It should be noted that, after the formed rubber is transferred to the extrusion die 300 , the glue spraying assembly 600 will spray solvent onto the rubber, so that the rubber can be firmly wrapped around the rope 700 .

[0053] It should be noted that the glue spraying assembly 600 can spray glue or some solvents that can dissolve the rubber so that the rubbers are adhered to each other.

[0054] See also Figure 1 , Figure 3 and Figure 4 As shown, in an optional scheme of this embodiment, the extrusion mold 300 includes an extrusion fixed mold 320 and an extrusion movable mold 310; the extrusion fixed mold 320 is fixedly set on the bracket 100, the extrusion movable mold 310 is slidably set on the bracket 100, and the extrusion movable mold 310 is connected to a first power source.

[0055] Specifically, the extrusion fixed die 320 of the extrusion die 300 is fixedly set on the bracket 100, and the extrusion movable die 310 is slidably set on the bracket 100. When the first power source is working, it can drive the extrusion movable die 310 to move toward the extrusion fixed die 320. During the movement, the extrusion movable die 310 will make the rubber wrap the rope 700, and the extrusion die 300 will compact the rubber so that the rubber firmly wraps the rope 700.

[0056] Among them, the first power source adopts a cylinder.

[0057] See also Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in an optional solution of this embodiment, the molding die 200 includes a molding fixed die 220 and a molding movable die 210 ; the molding fixed die 220 is disposed on the bracket 100 , and the molding movable die 210 is disposed on the extrusion movable die 310 .

[0058] Specifically, the molding movable mold 210 on the molding mold is fixedly arranged on the bracket 100, a tool holder 211 is arranged on the molding movable mold 210, a tool 212 is fixedly arranged on the tool holder 211, and a return spring 213 is arranged between the tool holder 211 and the molding movable mold 210. As the extrusion movable mold 310 moves, the extrusion movable mold 310 will push the tool holder 211 to move, so that the tool 212 on the tool holder 211 can perform molding work on the rubber in the molding mold 200 and cut the rubber into a set shape, without having to process the rubber beforehand, thereby reducing costs.

[0059] In addition, the opening and closing distance of the molding mold 200 is small, so when the molding mold 200 is completely opened, the rubber feeding assembly 500 will feed material into the molding mold 200, and the rubber on the rubber feeding assembly 500 will push the rubber in the molding mold 200 into the extrusion mold 300.

[0060] When the rubber feeding assembly 500 delivers the rubber into the forming mold 200, the rubber feeding assembly 500 stops working, thereby ensuring the length of the rubber supply.

[0061] The rubber feeding assembly 500 is provided with a sensor 530, through which it is possible to detect whether there is rubber being conveyed. After the user knows that there is no rubber, he can perform the rubber filling work.

[0062] It should be noted that when the extrusion movable die 310 moves, it will push the molding movable die 210 to move.

[0063] See also Figure 1 As shown, in an optional scheme of this embodiment, the glue spraying assembly 600 includes a solvent spraying member 610 and a spraying tube 620; the inlet of the solvent spraying member 610 is connected to the solvent source 630, and the outlet of the solvent spraying member 610 is connected to the spraying tube 620; the spraying tube 620 is used to spray the solvent onto the rubber in the extrusion mold 300.

[0064] Specifically, a solvent source 630 is disposed on the bracket 100 , and the solvent in the solvent source 630 flows into the solvent injection member 610 , and then the solvent is injected into the extrusion die 300 along the injection pipe 620 through the solvent injection member 610 .

[0065] The solvent injection part 610 adopts a plunger pump, and the solvent can be conveniently injected into the extrusion die 300 through the injection pump.

[0066] Specifically, the solvent source 630 is a liquid storage tank, the outlet of the liquid storage tank is connected to a plunger pump, a copper tube is provided at the outlet of the plunger pump, a nozzle is provided at the end of the copper tube (the copper tube and the nozzle form a spray tube 620), and the plunger pump moves back and forth through the cylinder, and a small amount of solvent is sprayed on the rope through the nozzle every time it moves. The size of the spray flow rate can be adjusted by a needle valve installed on the copper tube.

[0067] See also Figure 1 As shown, in an optional solution of this embodiment, the glue spraying assembly 600 also includes a heating element, which is used to heat and keep the rubber warm.

[0068] Specifically, the bracket 100 is also provided with a heating element, which heats and keeps the rubber warm, making it convenient to wrap the rubber on the rope 700.

[0069] See also Figure 1 As shown, in an optional scheme of this embodiment, the rope loading assembly 400 includes a damper 410 and a first roller 420 for winding the rope 700; the damper 410 is installed on the bracket 100, and the first roller 420 is installed on the damper 410, and the damper 410 rotates synchronously with the first roller 420 to tighten the rope 700.

[0070] Specifically, the damper 410 may be a rotary damper. The rotary damper can be provided to stabilize the rotation speed of the first drum 420 and keep the rope 700 discharged from the first drum 420 in a tensioned state.

[0071] See also Figure 1 As shown, in an optional solution of this embodiment, a tensioning wheel 430 for tensioning the rope 700 is provided on the bracket 100; a rotary encoder is connected to the tensioning wheel 430, and the rotary encoder is used to calculate the length of the conveyed rope 700.

[0072] Specifically, by setting a tensioning wheel 430 on the bracket 100, the tension of the rope 700 is further increased to ensure that the rope 700 is in a straightened state in the extrusion mold 300, thereby preventing the rubber from being unable to wrap around the rope 700 or the wrapping quality from being poor.

[0073] Among them, the length of the rope 700 that has been delivered can be calculated through the rotary encoder, so that the staff can calculate the length of the remaining rope 700 and facilitate the replenishment of materials.

[0074] See also Figure 1 As shown, in an optional solution of this embodiment, the rubber feeding assembly 500 includes a feed roller and a second roller 520 for winding the rubber; the feed roller and the second roller 520 are both installed on the bracket 100, and the feed roller is connected to a second power source.

[0075] Specifically, the rubber is driven by the feeding roller so that the rubber wound on the second roller 520 can be supplied into the molding die 200 .

[0076] The second power source drives the feed roller to rotate, so that the feed roller drives the rubber.

[0077] See also Figure 2 and Figure 3 As shown, in an optional scheme of this embodiment, the feed roller includes an active roller 511 and a driven roller 512, both of which are arranged on the bracket 100 and the active roller 511 is transmission-connected to the driven roller 512, and the active roller 511 is used to connect to the second power source.

[0078] Specifically, the second power source is connected to the active roller 511 through a coupling. When the second power source drives the active roller 511 to rotate, the first gear at the end of the active roller 511 away from the second power source will drive the second gear arranged on the driven roller 512 to rotate, so that the active roller 511 will drive the driven roller 512 to rotate, and the rubber will be driven through the active tube and the driven roller 512.

[0079] Among them, the second power source adopts a stepping motor, which can accurately convey the length of the rubber.

[0080] It should be noted that the rubber rubs the active roller 511 and the driven roller 512, and both the active roller 511 and the driven roller 512 have embossing that can increase friction. The driven roller 512 is movable and is pressed by a spring 513 to adapt to films of different thicknesses.

[0081] This embodiment provides a handbag stringing machine, including a heading structure. The heading structure is used to tie the rope of the handbag stringing machine. Compared with the prior art, the handbag stringing machine also has the above advantages, which will not be repeated here.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
