Description

Technical Field

[0001] This utility model relates to the field of pneumatic glue guns, and more particularly to a glue application device. Background Technology

[0002] High-speed trains require regular maintenance, including checking for loose screws. If a screw is found to be loose, glue needs to be applied and the screw tightened to prevent it from coming loose and causing a safety accident. Applying glue is typically done manually or with a pneumatic applicator. Since the glue is usually applied to screws on the bottom of the train, manual application may result in uneven application and is more difficult for workers. Current pneumatic applicators have the glue container inside the device, which may leave glue residue requiring cleaning. Furthermore, the overall size of these devices is bulky and inconvenient to carry and transport.

[0003] CN201710333134 discloses a user-friendly DC pneumatic glue gun, including a housing and a glue tube sleeve for mounting a glue tube. The rear end of the glue tube sleeve is sealed and fixed to the front end of the housing. An air pump, an air pump switch, a pressure relief valve, and a DC power supply are fixedly installed inside the housing. The air pump switch is electrically connected to both the DC power supply and the air pump. The air pump, the pressure relief valve, and the glue tube sleeve are all connected via air tubing. A button is hinged to the housing, which simultaneously controls the pressure relief valve and the air pump switch. This pneumatic glue gun's button controls both the pressure relief valve and the air pump switch, enabling one-button operation and making it convenient to use. However, the need for a glue tube sleeve at the front end of the housing results in a relatively large overall length of the glue gun, making it inconvenient to carry and transport.

[0004] The technical problem that this invention needs to solve is: how to improve the portability of the glue application device. Utility Model Content

[0005] The main purpose of this utility model is to provide a glue application device. By setting a connector on the machine housing to detachably connect to the glue syringe, the glue syringe can be removed from the machine housing when not in use, thereby reducing the overall length of the glue application device and facilitating transportation.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] An adhesive applicator includes a housing and an adhesive syringe; the housing is provided with a connector; the adhesive syringe is detachably connected to the housing via the connector; the adhesive syringe has an outlet and a sealing element that can slide along the inner wall of the adhesive syringe; the housing is provided with a power unit; the power unit is connected to the adhesive syringe; the power unit is used to push the sealing element to slide towards the outlet.

[0008] Preferably, the glue syringe and the connector are connected by threads or snaps to achieve a detachable connection between the glue syringe and the housing; the connector is provided with a first sealing ring; the side of the glue syringe away from the glue outlet abuts against the first sealing ring.

[0009] Preferably, the glue syringe is made of plastic; the capacity of the glue syringe is 5-15 mL.

[0010] Preferably, the glue syringe is provided with a flow guide needle; the flow guide needle is connected to the glue outlet.

[0011] Preferably, the power unit includes an air pump and a pressure relief module; the air pump is used to provide air pressure to the glue syringe to push the seal to slide towards the glue outlet; the pressure relief module is used to release the gas generated by the air pump inside the housing.

[0012] Preferably, the housing is provided with a pressure regulating chamber and an air pump installation chamber; the pressure relief module is located in the pressure regulating chamber; the air pump is located in the air pump installation chamber; the pressure regulating chamber and the air pump installation chamber are in communication.

[0017] Compared with existing technologies, this solution has the following advantages:

[0018] The glue application device in this case achieves a detachable connection between the glue syringe and the end of the machine housing by setting a connector at the end of the machine housing. This allows the glue syringe to be separated from the machine housing when no glue application is being performed, reducing the overall length of the glue application device and making it easier for workers to carry and transport.

[0019] Secondly, the glue syringe is equipped with a sliding seal. After the glue syringe is detached from the machine housing, the sealing effect of the seal may ensure that the glue in the glue syringe can be used for a certain period of time. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Example 1

[0026] refer to Figure 1-2 A glue application device includes a housing 1 and a glue syringe 2; the housing 1 is provided with a connector 3; the glue syringe 2 is detachably connected to the housing 1 via the connector 3; the glue syringe 2 is provided with a glue outlet 4 and a sealing element 5 that can slide along the inner wall of the glue syringe 2; the housing 1 is provided with a power unit 6; the power unit 6 is connected to the glue syringe 2; the power unit 6 is used to push the sealing element 5 to slide towards the glue outlet 4.

[0027] In this embodiment, the housing 1 has a cylindrical structure, and a connector 3 is provided at the front end of the housing 1. The glue syringe 2 is detachably connected to the housing 1 through the connector 3, eliminating the need for a cavity on the housing 1 to hold the glue syringe 2, thus reducing the overall length of the glue application device. Glue is stored between the glue outlet 4 and the sealing element 5; the sealing element 5 is a rubber piston that maintains the seal inside the glue syringe 2 and can also slide within the glue syringe 2.

[0028] The specific working process of this glue application device is as follows: When glue application is required, the operator connects the glue syringe 2 to the connector 3 and drives the power unit 6. The power unit 6 provides gas, which is blown from inside the housing 1 through the connector 3 to the surface of the seal 5, thereby pushing the seal 5 to slide towards the glue outlet 4, so that the glue in the glue syringe 2 flows out from the glue outlet 4 and is applied to the part.

[0029] Preferably, the glue syringe 2 and the connector 3 are connected by threads or snaps to achieve a detachable connection between the glue syringe 2 and the housing 1; the connector 3 is provided with a first sealing ring 7; the side of the glue syringe 2 away from the glue outlet 4 abuts against the first sealing ring 7.

[0030] In this embodiment, the glue syringe 2 and the connector 3 are preferably connected by a threaded connection to achieve a detachable connection between the glue syringe 2 and the housing 1. The connector 3 is a screw-in flange with a hollow structure. The inner hole of the screw-in flange is threaded, and the outer wall of the glue syringe 2 is threaded. The operator screws the glue syringe 2 to connect it to the connector 3, thereby fixing the glue syringe 2 to the front end of the housing 1.

[0031] Secondly, a first sealing ring 7 is placed inside the inner hole of the connector 3. When the glue syringe 2 is tightened, the rear end of the glue syringe 2 presses against the first sealing ring 7 to ensure the seal between the glue syringe 2 and the connector 3, and to prevent air leakage between the glue syringe 2 and the connector 3, which would affect the glue dispensing effect.

[0032] Preferably, the glue syringe 2 is made of plastic; the capacity of the glue syringe 2 is 5-15 mL.

[0033] In this embodiment, the glue syringe 2 is for single use and is replaced after use. Therefore, the glue syringe 2 is made of plastic to reduce costs.

[0034] Secondly, since the glue in glue syringe 2 contains volatile solvents, it is best to use glue syringe 2 in one go. Therefore, the capacity of glue syringe 2 is preferably 10mL, which can meet the glue application needs and avoid waste.

[0035] Preferably, the glue syringe 2 is provided with a flow guide needle 8; the flow guide needle 8 is connected to the glue outlet 4. The opening of the flow guide needle 8 is smaller than that of the glue outlet 4, which makes it easier for workers to apply glue to small areas.

[0036] Preferably, the power unit 6 includes an air pump 9 and a pressure relief module 10; the air pump 9 is used to provide air pressure to the glue syringe 2 to push the seal 5 to slide towards the glue outlet 4; the pressure relief module 10 is used to release the gas generated by the air pump 9 inside the housing 1.

[0037] In this embodiment, the air pump 9 supplies air into the housing 1, causing the air to pass through the connector 3 and blow into the glue syringe 2. When the air pressure inside the glue syringe 2 is greater than the ambient air pressure, the air pushes the seal 5 to slide inside the glue syringe 2, causing the glue to flow out from the dispensing port 4. When the glue syringe 2 is blocked, and the air pressure inside the glue syringe 2 exceeds a threshold, the pressure relief module 10 releases the air inside the housing 1, thereby reducing the air pressure inside the glue syringe 2 and preventing damage to the air pump 9. Furthermore, after use, the pressure relief module 10 can be driven to release the air inside the housing 1, preventing glue from continuing to flow out and causing pollution and waste.

[0038] Preferably, the housing 1 is provided with a pressure regulating chamber 11 and an air pump mounting chamber 12; the pressure relief module 10 is disposed in the pressure regulating chamber 11; the air pump 9 is disposed in the air pump mounting chamber 12; the pressure regulating chamber 11 and the air pump mounting chamber 12 are in communication.

[0039] In this embodiment, the air pump 9 is installed inside the air pump mounting compartment 12. The air pump 9 supplies air to the pressure regulating compartment 11, and the pressure regulating compartment 11 then supplies air to the glue syringe 2 through the connector 3. By setting up the pressure regulating compartment 11, the air supply can be made more stable.

[0040] Preferably, the housing 1 is provided with a button 13; the button 13 is used to control the opening and closing of the power unit 6. After the operator presses the button 13, the air pump 9 supplies air, thereby causing the glue in the glue syringe 2 to flow out; after the operator releases the button 13, the air pump 9 stops supplying air.

[0041] Preferably, the pressure relief module 10 is a pressure relief valve; the pressure relief valve is connected to the pressure regulating chamber 11.

[0042] In this embodiment, when the air pressure in the pressure regulating chamber 11 is higher than the threshold, the pressure relief valve is passively activated to release excess air, bringing the air pressure inside the pressure regulating chamber 11 below the threshold. Secondly, operators can manually open the pressure relief valve to release the gas inside the pressure regulating chamber 11 after use, preventing further glue leakage.

[0043] Preferably, the housing 1 is provided with a battery 14 and a charging port 15; the battery 14 is used to supply power to the power unit 6; and the charging port 15 is used to charge the battery 14. By providing the battery 14 and the charging port 15, the glue applicator does not need to be connected to an air source during use, thus improving the convenience of the glue applicator.

[0044] Example 2

[0045] refer to Figure 3This embodiment is basically the same as embodiment 1, except that: the housing 1 includes a first housing 16 and a second housing 17; the first housing 16 and the second housing 17 are detachably connected; the power unit 6 is disposed in the first housing 16; the battery 14 and the charging port 15 are disposed in the second housing 17; and the inner wall of the second housing 17 is provided with a second sealing ring 18.

[0046] In this embodiment, the first housing 16 and the second housing 17 are detachably connected by a snap-fit ​​mechanism. The housing 1 is divided into the first housing 16 and the second housing 17. When the battery 14 of the adhesive applicator is depleted, to avoid stopping the adhesive applicator operation due to the need for charging, the adhesive applicator can continue to operate simply by replacing the second housing 16. The old second housing 16 can be charged separately, thereby improving the adhesive applicator efficiency.

[0047] The battery 14 is connected to the power unit 6 via a battery connector 19 to prevent damage to the connection circuit between the battery 14 and the power unit 6 when the second housing 16 is removed. Furthermore, the inner wall of the second housing 16 is provided with a second sealing ring 18 to prevent external dust from entering the second housing 17 through the gap between the first housing 16 and the second housing 17.
