[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0027] See also Figure 1-4 As shown, the utility model is a device for heating and melting raw materials for woven bag production, comprising: a hot melt tank 1 and a feeding pipe 2, and the applied material is preheated through an outer ring seat 4 outside the feeding pipe 2;

[0028] The lower end of the feeding pipe 2 is provided with an extension pipe 3 connected to the hot melting tank 1. The inside of the feeding pipe 2 is provided with an inner ring seat 6 for internal heating of the raw materials. The upper end thereof is a conical structure so that the raw materials can be evenly dispersed and discharged. The inside of the inner ring seat 6 is provided with a guide tube 8, which is evenly distributed and forms a guide hole 9 inside to circulate the raw materials to increase the heating area thereof.

[0029] A lower ring seat 7 and an inner ring seat 6 are provided inside the lower end of the feeding pipe 2 to form an upper and lower double-layer structure, and a plug 11 is provided inside to be rotatably installed inside the guide hole 9 to crush the granular raw materials into powder to promote heating and prevent clogging;

[0030] This embodiment provides a hot melt device that can preheat raw materials at multiple points inside and outside. The diversion effect of the inner ring seat 6 is used in conjunction with the conduit 8 to increase the contact area, which effectively promotes the heating of the raw materials. At the same time, the plug 11 is used to crush and grind the raw materials to improve the heating efficiency while preventing blockage.

[0031] Among them, the heat generated by the heating wire 5 inside the outer ring seat 4 is transferred to the inside of the inner ring seat 6 through the adapter hole 10 near the lower end of the feeding tube 2, so that the conduit 8 is heated, thereby forming multi-point internal heating treatment for the raw material, avoiding the situation where the heat of the inner and outer circle areas is different and affects the subsequent hot melting effect.

[0032] Among them, a plurality of transmission ring frames 12 are arranged in layers inside and outside the lower ring seat 7, and are used to drive the plug 11 to rotate and promote material feeding. Both the inner and outer sides of the transmission ring frame 12 are protruding toothed mechanisms.

[0033] Among them, a device box 13 is provided at the lower end of the lower ring seat 7, and a boss 14 is provided at the lower end of the plug 11 at the center position of the lower ring seat 7 to connect to the motor inside the device box 13. The transmission ring frame 12 is distributed between adjacent bosses 14 to form a meshing connection, so that the transmission ring frame 12 and the plug 11 can be driven to rotate by applying source power through the motor.

[0034] The lower end of the transmission ring frame 12 is provided with a T-shaped ring frame 15 which is rotatably mounted on the bottom of the lower ring seat 7 , and the bottom of the ring seat 7 is provided with an inverted T-shaped ring groove body.

[0035] The conical structure above the lower ring seat 7 is used to guide the material outward for unloading to prevent it from entering the interior and affecting the operation of the transmission mechanism.

[0036] It is understandable that the utility model can preheat the raw materials at multiple points inside and outside, while increasing the contact area to promote heating efficiency, and grind the raw materials to improve the heat resistance while avoiding blockage.

[0037] A specific application of the operation process of this embodiment is: when in use, first use the tapered surface of the inner ring seat 6 to disperse the raw material so that it slides downward through the guide hole 9. At this time, use the adapter hole 10 to introduce the heat source inside the outer ring seat 4 into the interior of the inner ring seat 6 and increase the contact area with the raw material through the conduit 8. After this arrangement, the raw material can be preheated in multiple directions at the same time, so that it can quickly reach a predetermined stability for subsequent hot melting treatment. During the material discharge process, the transmission ring frame 12 and the convex disk 14 can also be used to drive the adjacent plug 11 to rotate to crush the raw material inside the guide hole 9, so that the granular raw material is converted into a powdery material, while also promoting its heating efficiency, and avoiding blockage due to particle accumulation, so as to ensure efficient and stable operation of the equipment.
