Description

Technical Field

[0001] This utility model relates to the field of glue spray gun technology, specifically a vertically distributed double-headed glue spray gun. Background Technology

[0002] A glue spray gun is a tool that can evenly spray glue onto the surface of an object. It is widely used in construction, furniture manufacturing, automobile manufacturing, and handicrafts. Glue spray guns are usually used in conjunction with a dispensing valve, a device used to control the flow of liquid or semi-solid substances. This valve is commonly used in industrial production, especially in the fields of glues and adhesives. The main function of the dispensing valve is to regulate the flow rate and volume of the glue to ensure that the glue is accurately directed to the desired location during the production process.

[0003] However, existing dispensing valves typically control dispensing by a striking pin. When dispensing is needed, the striking pin moves upward, opening the dispensing port and allowing dispensing. When dispensing needs to be stopped, the striking pin moves downward, closing the dispensing port and stopping dispensing. However, when dispensing is stopped, the downward movement of the striking pin can easily cause residual adhesive to be squeezed out, resulting in leakage, which fails to meet actual needs.

[0004] To address this, we propose a vertically distributed dual-head glue gun. Utility Model Content

[0005] The purpose of this invention is to provide a vertically distributed dual-head glue gun to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertically distributed dual-head glue gun, comprising a glue application module, wherein the glue application module is provided with two sets of glue application components, each set of glue application components including a glue dispensing valve and a glue dispensing head, each glue dispensing head having multiple nozzles spaced apart, and the included angle between two glue dispensing heads being 90°, each glue dispensing valve having a striking pin, the bottom of the striking pin having a control head, the bottom of the glue outlet of each glue dispensing valve having a glue dispensing ring, the control head being located below the glue dispensing ring, and the top of the control head cooperating with the bottom structure of the glue dispensing ring, wherein when the control head moves downward, glue flows out from the glue dispensing ring, and when the control head moves upward and fits against the glue dispensing ring, glue dispensing stops.

[0007] The difference between this utility model and the prior art lies in the fact that when the control head moves downward, the adhesive flows out from the dispensing ring, and when the control head moves upward and fits with the dispensing ring, the dispensing stops. Moreover, no pressure is generated during the upward movement, which can instead achieve the effect of drawing the adhesive upward. Therefore, there will be no adhesive leakage, which can meet the actual needs.

[0008] Furthermore, the multiple nozzles on each of the dispensing heads are evenly distributed.

[0009] The above technical solution can make the adhesive sprayed from multiple nozzles more uniform.

[0010] Furthermore, each of the dispensing heads has a dispensing cavity, the control head is located in the dispensing cavity, and the dispensing valve has a glue inlet channel, which is connected to the dispensing cavity.

[0011] Through the above technical solution: since the control head is located inside the dispensing chamber, a certain negative pressure will be formed inside the dispensing chamber during the upward movement, which can actually achieve the effect of drawing the glue upward and avoid glue leakage when the glue is stopped.

[0012] Furthermore, each of the dispensing valves corresponds to a dispensing head, and a sealing ring is provided between the dispensing channel on each dispensing valve and the dispensing cavity on the corresponding dispensing head.

[0013] The above technical solution can make the connection between the dispensing valve and the dispensing head tighter, thus preventing glue leakage.

[0014] Furthermore, each of the control heads is provided with a flange at its top, and each control head engages with a corresponding dispensing ring via the flange.

[0015] The above technical solution allows for a tighter seal on the dispensing ring by controlling the flange at the top of the head to fit snugly against the dispensing ring, thus preventing glue from overflowing when dispensing is stopped.

[0016] Furthermore, each of the dispensing cavities has a connecting channel at its bottom.

[0017] Furthermore, each of the dispensing heads is provided with a glue guiding channel, and the nozzle on each dispensing head is connected to the glue guiding channel.

[0018] Furthermore, the dispensing cavity of each dispensing head is connected to the dispensing channel through the aforementioned connecting channel.

[0019] With the above technical solution, the adhesive can pass through the connecting channel and the guiding channel in sequence from the dispensing chamber, and finally be discharged through multiple nozzles.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] Firstly, the difference between this utility model and the prior art is that when the control head moves downward, the adhesive flows out from the dispensing ring, and when the control head moves upward and fits with the dispensing ring, the dispensing stops. Moreover, no pressure is generated during the upward movement, which can instead achieve the effect of drawing the adhesive upward. Therefore, there will be no adhesive leakage, which can meet the actual needs.

[0022] Secondly, in this invention, the included angle between the two dispensing heads is 90°, meaning they are vertically distributed. Therefore, during the actual dispensing process, both horizontal and vertical dispensing can be achieved by moving the dispensing head in both directions. Users can choose according to their actual needs without additional adjustments, making it more flexible to use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5A vertically distributed dual-head glue gun includes a glue application module 1, which has two sets of glue application components. Each set of glue application components includes a glue dispensing valve 2 and a glue dispensing head 3. Each glue dispensing head 3 has multiple nozzles 4 spaced apart, and the included angle between two glue dispensing heads 3 is 90°. Each glue dispensing valve 2 has a striking pin 5, and a control head 6 is located at the bottom of the striking pin 5. Each glue dispensing valve 2 has a glue dispensing ring 8 at the bottom of the glue outlet. The control head 6 is located below the glue dispensing ring 8, and the top of the control head 6 is matched with the bottom structure of the glue dispensing ring 8. When the control head 6 moves downward, glue flows out from the glue dispensing ring 8. When the control head 6 moves upward and fits against the glue dispensing ring 8, glue dispensing stops.

[0031] It should be noted that the difference between this utility model and the prior art is that when the control head 6 moves downward, the adhesive flows out from the dispensing ring 8, and when the control head 6 moves upward and comes into contact with the dispensing ring 8, the dispensing stops. Moreover, no pressure is generated during the upward movement, which can instead achieve the effect of drawing the adhesive upward. Therefore, there will be no adhesive leakage, which can meet the actual needs.

[0032] It is worth mentioning that in this utility model, the included angle of the two glue dispensing heads 3 is 90°, that is, they are vertically distributed. Therefore, in the actual glue spraying process, when moving the glue in both the horizontal and vertical directions, both horizontal and linear glue spraying can be achieved. Users can choose according to their actual needs without additional adjustments, making it more flexible to use.

[0033] Specifically, the multiple nozzles 4 on each dispensing head 3 are evenly distributed, which makes the adhesive sprayed from the multiple nozzles 4 more uniform.

[0034] Specifically, each dispensing head 3 has a dispensing chamber 11, the control head 6 is located in the dispensing chamber 11, and the dispensing valve 2 has a dispensing channel 9, which is connected to the dispensing chamber 11.

[0035] With this setup, since the control head 6 is located inside the dispensing chamber 11, a certain negative pressure will be formed inside the dispensing chamber 11 during the upward movement. Therefore, it can actually draw the glue upward, thus preventing glue leakage when the glue is stopped.

[0036] Specifically, each dispensing valve 2 corresponds to a dispensing head 3, and a sealing ring 10 is provided between the glue inlet channel 9 on each dispensing valve 2 and the glue dispensing cavity 11 on the corresponding dispensing head 3.

[0037] By setting the sealing ring 10, the connection between the dispensing valve 2 and the dispensing head 3 can be made tighter, thus preventing glue leakage.

[0038] Specifically, each control head 6 is provided with a flange 13 on its top. Each control head 6 is engaged with the corresponding glue dispensing ring 8 through the flange 13. By having the flange 13 on the top of the control head 6 fit against the glue dispensing ring 8, the seal for the glue dispensing ring 8 can be made tighter, preventing glue from overflowing when the glue dispensing is stopped.

[0039] Specifically, each dispensing cavity 11 has a connecting channel 12 at its bottom, each dispensing head 3 has a guiding channel 7, and each nozzle 4 on each dispensing head 3 is connected to the guiding channel 7. The dispensing cavity 11 on each dispensing head 3 and the guiding channel 7 are connected through the connecting channel 12.

[0040] Through the above technical solution, the adhesive can pass through the connecting channel 12 and the guiding channel 7 in sequence from the dispensing chamber 11, and finally be discharged through multiple nozzles 4.
