[0002] During the production and processing of electric vehicle headlight covers, it is generally necessary to apply adhesive to the outer edge of the headlight cover. Currently, the adhesive application for electric vehicle headlight covers is mainly done by an adhesive dispensing machine. When using an adhesive dispensing machine, the adhesive material needs to be heated.

[0003] A search revealed a heating device for a dispensing machine, disclosed in publication number CN210546099U. This device includes a worktable fixing plate and an adjustable temperature heating plate on the worktable fixing plate, with a heat insulation plate between the worktable fixing plate and the adjustable temperature heating plate. This heating device is simple to operate and convenient to use; it heats the adhesive during application, improving filling efficiency, and eliminates the need for additional preheating of the workpiece, reducing the number of heating steps.

[0004] The heating components of the aforementioned dispensing machine heat synchronously during use. However, these components only heat the surface and cannot ensure uniform heating, thus affecting the uniformity of dispensing. To address this issue, we designed a heating component for a dispensing machine used in the processing of electric vehicle headlight covers. Summary of the Invention

[0005] The purpose of this invention is to provide a heating component for a dispensing machine used in the processing of headlight covers for electric vehicles, in order to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solution: a heating component for a dispensing machine used in the processing of headlight covers for electric vehicles, comprising a dispensing machine body, an assembly base slidably connected to the top of the dispensing machine body, a material barrel fixedly installed at the top of the assembly base, a turntable rotatably connected inside the material barrel, multiple heating rods fixedly installed at equal intervals at the top of the turntable, a discharge pipe fixedly connected to the top of the material barrel via a material pump, a material nozzle fixedly provided at the center of the bottom end of the assembly base, the discharge pipe passing through the assembly base and communicating with the material nozzle inlet end, a circular groove being provided at the intersection of the discharge pipe and the assembly base, a spiral heating ring being fixedly installed inside the circular groove, and the spiral heating ring being nested and connected to the discharge pipe.

[0007] In the heating assembly of the dispensing machine for processing headlight covers of electric vehicles, the assembly base has a cavity inside.

The bottom end of the connecting shaft extends into the cavity and is fixedly installed with a second bevel gear. A servo motor is fixedly installed on the side of the cavity. A first bevel gear is fixedly installed on the output shaft of the servo motor. The first bevel gear and the second bevel gear are meshed and connected.

[0008] In the heating assembly of the dispensing machine for processing electric vehicle headlight covers, a power cord is inserted and connected at the center of the connecting shaft, and multiple heating rods are electrically connected to an external power source through the power cord.

[0009] In the heating assembly of the dispensing machine for processing the headlight cover of the electric vehicle described above, a plurality of heat dissipation holes are provided on one side of the cavity, and a dustproof mesh is fixedly installed inside each of the plurality of heat dissipation holes.

[0010] In the heating assembly of the dispensing machine for processing electric vehicle headlight covers, the surface of the material barrel is covered with an insulating sleeve, the inside of the insulating sleeve is a vacuum chamber, one side of the vacuum chamber is an exhaust hole communicating with the outside, and a sealing plug is nested inside the exhaust hole.

[0011] In the heating assembly of the dispensing machine for processing the headlight cover of the electric vehicle described above, the inner diameter of the heat insulation sleeve is adapted to the outer diameter of the material barrel, and a sealing ring is provided at the connection between the heat insulation sleeve and the top of the material barrel.

[0012] Compared with the prior art, the advantages of the dispensing machine heating component for processing electric vehicle headlight covers of this utility model are:

[0013] 1. By setting multiple heating rods in the turntable inside the material barrel, not only can the material inside the barrel be heated, but the material can also be stirred during the heating process, which improves the uniformity of material heating.

[0014] 2. After the material enters the nozzle through the discharge pipe, it is heated a second time by the spiral heating ring, which further ensures the molten state of the material and ensures the uniformity of adhesive dispensing during the dispensing process. Attached Figure Description

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1-4 As shown, the heating component of the dispensing machine for processing electric vehicle headlight covers of this utility model includes a dispensing machine body 1. An assembly base 2 is slidably connected to the top of the dispensing machine body 1. A material tank 3 is fixedly installed at the top of the assembly base 2. A turntable 7 is rotatably connected inside the material tank 3. Multiple heating rods 6 are fixedly installed at equal intervals at the top of the turntable 7. A discharge pipe 4 is fixedly connected to the top of the material tank 3 through a material pump. A material nozzle 10 is fixedly provided at the center of the bottom end of the assembly base 2. The discharge pipe 4 passes through the assembly base 2 and communicates with the inlet end of the material nozzle 10. A circular groove 11 is opened at the intersection position of the discharge pipe 4 and the assembly base 2. A spiral heating ring 12 is fixedly installed inside the circular groove 11. The spiral heating ring 12 is nested and connected to the discharge pipe 4.

[0022] Specifically, by setting multiple heating rods 6 in the turntable 7 inside the material barrel 3, not only can the material inside the material barrel 3 be heated, but the material can also be stirred during the heating process, thereby improving the uniformity of material heating.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heating assembly of the dispensing machine for processing electric vehicle headlight covers of this utility model has a cavity 9 inside the mounting base 2. A connecting shaft 16 is rotatably connected between the center of the bottom end of the turntable 7 and the material barrel 3. The bottom end of the connecting shaft 16 extends into the cavity 9 and is fixedly installed with a second bevel gear 18. A servo motor 15 is fixedly installed on the side of the cavity 9. A first bevel gear 17 is fixedly installed on the output shaft of the servo motor 15. The first bevel gear 17 and the second bevel gear 18 are meshed and connected.

[0024] Specifically, the servo motor 15 drives the first bevel gear 17 to rotate, and the first bevel gear 17 meshes with the second bevel gear 18, thereby driving the rotation of the connecting shaft 16, which in turn drives the rotation of the turntable 7.

[0025] A power cord is inserted at the center of the connecting shaft 16, and multiple heating rods 6 are electrically connected to an external power source through the power cord.

[0026] Multiple heat dissipation holes 8 are provided on one side of the cavity 9, and dustproof mesh is fixedly installed inside each of the multiple heat dissipation holes 8.

[0027] Specifically, the opening of the heat dissipation hole 8 facilitates heat dissipation inside the cavity 9.

[0028] A heat-insulating sleeve 5 is attached to the surface of the material barrel 3. A vacuum chamber 13 is opened inside the heat-insulating sleeve 5. An exhaust hole communicating with the outside is opened on one side of the vacuum chamber 13. A sealing plug 14 is nested inside the exhaust hole.

[0029] Specifically, the vent holes facilitate the extraction of gas from the vacuum chamber 13, thereby improving the heat insulation performance of the insulation sleeve 5.

[0030] The inner diameter of the insulation sleeve 5 is matched with the outer diameter of the material barrel 3, and a sealing ring is provided at the connection between the insulation sleeve 5 and the top of the material barrel 3.

[0031] Specifically, by covering the material bucket 3 with the insulation jacket 5, a good insulation effect is achieved, reducing heat loss.

[0032] In specific implementation, when using the heating component of the dispensing machine for processing electric vehicle headlight covers, when the material is injected into the material barrel 3, the heating rod 6 and servo motor 15 are turned on. The heating rod 6 heats the material inside the material barrel 3, and the servo motor 15 drives the first bevel gear 17 to rotate. The first bevel gear 17 meshes with the second bevel gear 18, thereby driving the connecting shaft 16 to rotate. The rotation of the connecting shaft 16 drives the turntable 7 to rotate, and the rotation of the turntable 7 drives the heating rod 6 to rotate and stir, improving the uniformity of material heating. When the material flows into the nozzle 10 through the discharge pipe 4, it is further heated by the spiral heating ring 12 inside the circular groove 11, ensuring the molten state of the material and ensuring the uniformity of adhesive dispensing during the dispensing process.
