Description

Technical Field

[0001] This utility model relates to the field of grinding head manufacturing technology, specifically to a grinding head dispensing device. Background Technology

[0002] A grinding head is a general term for a small, shanked grinding tool used in electric grinders, pendant grinders, and hand drills. There are many types, including ceramic grinding heads, rubber grinding heads, diamond grinding heads, and abrasive cloth grinding heads. Ceramic grinding heads: The abrasive grains (generally brown corundum, white corundum, chromium corundum, or silicon carbide) are sintered from a ceramic binder, with a metal shank in the center. They are mainly used for grinding various metals, for grinding the inner walls of holes, and for mold correction.

[0003] In the production of existing ceramic grinding heads, a grinding head rod needs to be installed on the grinding head. When installing the grinding head rod, it is generally necessary to apply glue to the rod groove of the grinding head first to ensure adhesion when the grinding head rod is inserted later. In the existing grinding head glue application device, the glue tube is exposed and lacks heating and heat preservation measures. When the temperature is low, the glue is prone to solidification, which can affect the processing efficiency and effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in existing ceramic grinding head dispensing devices, the glue cartridge is exposed to the outside and lacks heating and insulation measures. When the temperature is low, the glue is prone to solidification, which can affect the processing efficiency and effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dispensing device for producing a grinding head, characterized in that: it includes a tank and a glue cylinder detachably disposed within the tank; one end of the tank is provided with a dispensing head communicating with the glue cylinder; a ceramic protective sleeve is disposed within the tank; the glue cylinder is fitted inside the ceramic protective sleeve; an electric heating wire is disposed between the ceramic protective sleeve and the inner wall of the tank; a pushing component is provided at the end of the glue cylinder away from the dispensing head for dispensing glue from the glue cylinder to the dispensing head; and a locking component is provided at the end of the tank away from the dispensing head for locking the pushing component.

[0007] A further improvement is that the locking assembly includes a U-shaped frame, with the U-shaped end of the U-shaped frame hinged to the two side walls of the tank at the end away from the dispensing head, and a locking rod threaded to the other end of the U-shaped frame. A top block is fixedly connected to the end of the locking rod facing the pneumatic mechanism, and a knob is connected to the other end of the locking rod.

[0008] A further improvement is that the glue-pushing assembly includes a support frame, with a cylindrical glue tube plug at one end of the support frame facing the glue tube, and a pneumatic mechanism at the other end of the support frame. One end of the glue tube plug is connected to the glue tube, and the other end of the glue tube plug is connected to the air outlet of the pneumatic mechanism. The air inlet of the pneumatic mechanism is connected to an external air pressure generating device through an air inlet pipe.

[0009] A further improvement is that the electric heating wire includes a wire connector for connecting to an external power source.

[0010] A further improvement is that the glue tube has a skirt on the side wall facing the glue pushing assembly, which facilitates the installation and removal of the glue tube. When it is necessary to replace the glue tube, the skirt can be used with tools to easily and quickly replace it.

[0011] A further improvement is that a liquid level observation port is provided on the surface of the tank. This observation port allows for convenient monitoring of the amount of glue remaining in the glue container.

[0012] A further improvement is that a tank drive cylinder is provided below the tank body to move the tank body toward the grinding head to be injected with glue, and the output end of the tank drive cylinder is fixedly connected to the bottom surface of the tank body.

[0013] Compared with existing technologies, the above technical solution has the following advantages:

[0014] The overall structure is simple. The heat insulation and heating process can prevent the glue from solidifying during use, ensuring the effect and efficiency of glue injection. The ceramic protective sleeve conducts heat and can better protect the glue cylinder while heating and heat insulation. The locking component can lock the glue pushing component to prevent the glue pushing component from shifting or falling off during glue injection, thus ensuring the production effect and efficiency of glue injection.

[0021] See Figures 1-4 As shown, the technical solution adopted in this specific embodiment is: a dispensing device for producing a grinding head, characterized in that: it includes a tank body 1 and a glue cylinder 3 detachably disposed inside the tank body 1. One end of the tank body 1 is provided with a dispensing head 5 communicating with the glue cylinder 3. A ceramic protective sleeve 2 is disposed inside the tank body 1. The glue cylinder 3 is sleeved inside the ceramic protective sleeve 2. An electric heating wire 4 is disposed between the ceramic protective sleeve 2 and the inner wall of the tank body 1. A glue pushing component 6 is provided at the end of the glue cylinder 3 away from the dispensing head 5 for dispensing glue from the glue cylinder 3 to the dispensing head 5. A locking component is provided at the end of the tank body 1 away from the dispensing head 5 for locking the glue pushing component 6.

[0022] The locking assembly includes a U-shaped frame 7, with the U-shaped end of the U-shaped frame 7 hinged to the two side walls of the tank body 1 away from the dispensing head 5. The other end of the U-shaped frame 7 is threadedly connected to a locking rod 8. The locking rod 8 is fixedly connected to a top block 9 at the end facing the pneumatic mechanism 63, and a knob 10 is connected to the other end of the locking rod 8.

[0023] The adhesive pushing assembly 6 includes a support frame 61. A cylindrical adhesive tube plug 62 is provided at one end of the support frame 61 facing the adhesive tube 3. An air pressure mechanism 63 is provided at the other end of the support frame 61. One end of the adhesive tube plug 62 is connected to the adhesive tube 3, and the other end of the adhesive tube plug 62 is connected to the air outlet of the air pressure mechanism 63. The air inlet of the air pressure mechanism 63 is connected to an external air pressure generating device through an air inlet pipe 64.

[0024] The electric heating wire 4 includes a wire connector 41 for connecting to an external power source.

[0025] The glue cartridge 3 has a skirt 31 on its side wall facing the glue pushing assembly 6, which facilitates the installation and removal of the glue cartridge 3. When it is necessary to replace the glue cartridge 3, the glue cartridge 3 can be easily and quickly replaced using tools and the glue cartridge skirt 31.

[0026] The surface of the tank 1 is provided with a liquid level observation port 11. The liquid level observation port 11 allows for convenient observation of the amount of glue in the glue container 3.

[0027] The tank body 1 is provided with a tank driving cylinder 12 below it, which is used to push the tank body 1 towards the grinding head to be injected with glue. The output end of the tank driving cylinder 12 is fixedly connected to the bottom surface of the tank body 1.

[0028] The working principle of this invention is as follows: In use, insert the glue tube filled with glue into the ceramic protective sleeve of the container. Then, align the glue tube plug of the glue-pushing assembly with the glue tube. Next, rotate the U-shaped frame to align the top block of the locking rod with the back of the pneumatic mechanism of the glue-pushing assembly. Then, rotate the locking rod by turning the knob to lock the top block against the pneumatic mechanism, preventing the glue-pushing assembly from shifting and affecting the glue-pushing effect. Simultaneously, the glue tube is heated and kept warm by the electric heating wire, preventing the glue from solidifying during the glue-pushing process. Since the glue tube is generally made of plastic, the ceramic protective sleeve conducts heat, avoiding direct heating of the glue tube and better protecting it, thus extending its service life. After the glue is used up, unscrew the top block, unrotate the U-shaped frame, disassemble the glue-pushing assembly, remove the glue tube, replace it with a full glue tube, and repeat the above steps.
