Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing machine heads, in particular to a glue dispensing machine head that prevents glue from leaking. Background Art

[0002] The dispensing head, a core component of the dispensing machine, is responsible for applying glue to the surface of the material being bonded at the precise location. It controls the flow of glue, ensuring precise and stable application to the target location. It is a key component in achieving the precise dispensing and coating functions of the dispensing machine.

[0003] When there are problems with the parameters and other settings within the glue dispenser, some glue leakage may occur. The "anti-glue leaking machine head" disclosed in the authorization announcement number "CN 206653582 U" achieves a sealing effect by tightly fitting the discharge shaft core with the gun body, thereby preventing glue dripping.

[0004] However, in actual use, this structure proved to be overly complex and prone to malfunction, resulting in occasional glue leaks. This not only made the production site messy and difficult to clean and manage, but also increased factory maintenance time and costs. Therefore, a dispensing head that could prevent glue from dripping onto the production site was urgently needed. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a glue dispensing head that prevents glue from leaking.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A glue-leakage-proof dispensing machine head comprises a glue-leakage-proof dispensing machine head body, a glue-leakage-dispensing assembly being provided on the glue-leakage-dispensing machine head body, an installation cavity being provided on the glue-leakage-dispensing machine head body behind the glue-leakage-dispensing assembly, and a first special-shaped part and a second special-shaped part being assembled in the installation cavity; a glue-collecting cavity being provided above the first special-shaped part, the glue-collecting cavity being located below the glue-dispensing assembly, a card cavity being provided on one side of the glue-collecting cavity at the bottom of the first special-shaped part, and a card block being adapted to correspond to the card cavity on the second special-shaped part.

[0008] In addition, a preferred structure is that a positioning column is fixedly and vertically arranged on one side of the installation cavity, and a positioning cavity is vertically penetrated on the second special-shaped member corresponding to the positioning column.

[0009] In addition, a preferred structure is that a mounting piece is fixedly provided on the first special-shaped piece, and the mounting piece is adapted to be inserted into the mounting cavity.

[0010] In addition, a preferred structure is that the mounting piece is inserted inward from a side of the mounting cavity away from the positioning column, and when the mounting piece is inserted into the mounting cavity, the mounting piece contacts the second special-shaped piece.

[0011] In addition, a preferred structure is that a limiting column is fixed vertically downward on the top of the card cavity, and a limiting cavity is vertically penetrated by the corresponding limiting column on the card block.

[0012] In addition, a preferred structure is that the card cavity, the card block, the limiting column, and the side walls of the limiting cavity that are in contact with each other are all paved with anti-slip pads.

[0013] The beneficial effects of the present invention are as follows: through the clamping arrangement between the clamping cavity, the clamping block, the limiting column and the limiting cavity, the first special-shaped part and the second special-shaped part can be quickly installed on the dispensing machine head body, and the glue collecting cavity is located below the dispensing component, so that the glue dripping from the dispensing component can be collected, thereby preventing the glue leaked from the dispensing component from dripping into the production site, thereby reducing the maintenance cost of the production site.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-5 A glue dispensing head for preventing glue leakage comprises a glue dispensing head body 1, a glue dispensing assembly 11 is provided on the glue dispensing head body 1, an installation cavity 12 is provided on the glue dispensing head body 1 at the rear of the glue dispensing assembly 11, and a first special-shaped part 2 and a second special-shaped part 3 are assembled in the installation cavity 12. A glue collecting cavity 21 is provided above the first special-shaped part 2, and the glue collecting cavity 21 is located below the glue dispensing assembly 11. A card cavity 22 is provided on the bottom of the first special-shaped part 2 on one side of the glue collecting cavity 21, and a card block 32 is adapted to fit the card cavity 22 on the second special-shaped part 3. Gluing of the workpiece can be achieved by the glue dispensing assembly 11 on the glue dispensing head body 1, and it is worth noting that the specific structure of the glue dispensing head body 1 and the glue dispensing assembly 11 and their working methods are all existing technologies currently disclosed on the market, which are common knowledge well known to those skilled in the art, and do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0022] Among them, a positioning column 4 is fixed vertically on one side of the installation cavity 12, and a positioning cavity 31 is vertically penetrated on the second special-shaped member 3 corresponding to the positioning column 4. The second special-shaped member 3 can be installed by the adaptation of the positioning column 4 and the positioning cavity 31.

[0023] Among them, the first special-shaped member 2 is fixedly provided with a mounting member 24, and the mounting member 24 is adapted to be inserted into the mounting cavity 12. By inserting the mounting member 24 into the mounting cavity 12 and cooperating with the clamping between the clamping cavity 22 and the clamping block 32, the first special-shaped member 2 can be installed.

[0024] The mounting member 24 is inserted inward from the side of the mounting cavity 12 away from the positioning post 4. When the mounting member 24 is inserted into the mounting cavity 12, the mounting member 24 contacts the second special-shaped member 3. The contact areas of the mounting member 23 and the second special-shaped member 3 are respectively provided with magnetic blocks of different polarity. The provision of the different polarity magnetic blocks allows the mounting member 23 and the second special-shaped member 3 to be attracted to each other.

[0025] A limit post 23 is fixed vertically downwardly at the top of the clamping cavity 22, and a limit cavity 33 is vertically penetrated on the clamping block 32 corresponding to the limit post 23. Anti-slip pads are provided on the contacting sidewalls of the clamping cavity 22, the clamping block 32, the limit post 23, and the limit cavity 33. The provision of anti-slip pads improves the stability of the contact areas, thereby enhancing the installation stability between the first and second shaped parts 2 and 3.

[0026] In this embodiment, when the user does not need to use this device for processing, the user can first insert the second special-shaped member 3 into the installation cavity 12, then move the second special-shaped member 3 downward so that the positioning cavity 31 provided therein engages with the positioning post 4. The user can then insert the installation member 24 on the first special-shaped member 2 into the installation cavity 12, and then engage the locking cavity 22 at the bottom of the first special-shaped member 2 with the locking block 32 on the second special-shaped member 3.

[0027] Furthermore, when the card cavity 22 is fixed on the card block 32, since the limiting post 23 is provided inside the card cavity 22, the limiting post 23 will also be synchronously fixed in the limiting cavity 33 opened in the card block 32, thereby realizing the splicing between the first special-shaped part 2 and the second special-shaped part 3. In addition, the first special-shaped part 2 and the second special-shaped part 3 can also be fixed on the dispensing head body 1. At this time, the glue collecting cavity 21 on the first limiting part 2 is located below the dispensing component 11, so that the glue dripping from the dispensing component 11 can be collected, thereby not causing damage to the production site. At this time, the user needs to inspect the dispensing head body 1 to find the cause of the glue leakage and perform maintenance. In this way, the phenomenon of glue leakage in the dispensing component 11 can be prevented when the user does not use the device for a short time, thereby preventing glue from dripping on the production site.

[0028] In the present invention, the first special-shaped part 2 and the second special-shaped part 3 can be quickly installed on the dispensing machine head body 1 through the clamping arrangement between the clamping cavity 22, the clamping block 32 and the limiting column 23 and the limiting cavity 33, and the glue collecting cavity 21 is located below the dispensing component 11, so that the glue dripping from the dispensing component 11 can be collected, thereby preventing the glue leaked from the dispensing component 11 from dripping into the production site, thereby reducing the maintenance cost of the production site.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
