Two-component gear-driven electric glue gun

Abstract

This utility model discloses a two-component gear-driven electric glue gun, including a first housing, a second housing at one end of the first housing, a third housing at the bottom of the second housing, a handle at the bottom of the third housing, and a base at the bottom of the handle. Two push rods are symmetrically arranged inside the first housing, each push rod having a piston at one end. The other ends of the two push rods are fixedly connected by a transmission plate. When the glue in the glue cartridge is cleared, as the push rod continues to move, the distance between the second magnet and the first magnet decreases until the pushing force of the second magnet on the first magnet exceeds the elastic force of the second spring. At this point, the second adjusting rod separates from the first sliding groove, and the second limiting plate is lifted by the elastic force of the first spring. At this time, the driven bevel gear separates from the driving bevel gear, and the push rod stops moving. This prevents damage to the internal parts of the glue gun due to overload and improves the service life of the glue gun.

Description

Technical Field

[0001] This utility model relates to the field of electric glue gun technology, and in particular to a two-component gear-driven electric glue gun. Background Technology

[0002] In industrial manufacturing, construction and decoration, and DIY scenarios, two-component adhesives are widely used for material bonding due to their excellent adhesion and curing effect. The two-component glue gun is a key component in glue application, and its performance directly affects the quality and efficiency of the application. Existing electric two-component glue guns generally use gears as a transmission mechanism to drive the push rod. Although current glue guns are more efficient than manual glue application, they still have shortcomings. For example, electric glue guns typically control the motor's operation via a switch, which requires workers to constantly monitor the glue level in the cartridge. If the motor is not stopped promptly after the glue is depleted, internal components may be damaged due to overload, reducing the glue gun's lifespan. Utility Model Content

[0003] The purpose of this utility model is to provide a two-component gear-driven electric glue gun in order to solve the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A two-component gear-driven electric glue gun includes a first housing, a second housing at one end of the first housing, a third housing at the bottom of the second housing, a handle at the bottom of the third housing, and a base at the bottom of the handle. Two push rods are symmetrically arranged inside the first housing, each push rod having a piston at one end. The other ends of the two push rods are fixedly connected by a transmission plate. The push rods pass through the second housing and are slidably connected to it. A toothed plate is provided on the opposite side of each of the two push rods. A gear transmission part for driving the push rods is provided inside the third housing.

[0006] Preferably, the gear transmission unit includes a first gear and a second gear, which are meshed together. The first gear meshes with one of the gear plates, and the second gear meshes with another gear plate. A first rotating shaft is provided at the bottom of the first gear and is rotatably connected to the second housing. A second rotating shaft is provided at the bottom of the second gear and is rotatably connected to the second housing. A first limiting plate is provided between the first and second rotating shafts and is rotatably connected to the first limiting plate. A transmission mechanism for driving the first rotating shaft to rotate is provided inside the third housing.

[0007] Preferably, the transmission mechanism is a drive motor located inside the third housing. The output end of the drive motor is provided with a drive bevel gear. The inner wall of the third housing is provided with a second limiting plate. A third rotating shaft is rotatably connected to the second limiting plate. One end of the third rotating shaft is provided with a driven bevel gear that meshes with the drive bevel gear. The other end of the third rotating shaft is provided with a limiting post. A limiting hole is opened at the bottom of the first rotating shaft. The limiting post and the limiting hole are slidably connected.

[0008] Preferably, the third housing has a strip-shaped hole on its upper surface, a first sliding rod is disposed in the strip-shaped hole, the second limiting plate is slidably connected to the first sliding rod, a support plate is disposed on the side of the third housing, a first spring is disposed between the support plate and the second limiting plate, a second sliding groove is disposed on the side of the third housing, a transmission rod is slidably connected in the second sliding groove, a second adjusting rod is disposed on the side of the transmission rod, a first sliding groove is disposed on the upper end face of the second limiting plate, and the second adjusting rod is slidably connected to the first sliding groove.

[0010] Preferably, a second slide rod is provided in the second slide groove, the second slide rod and the transmission rod are slidably connected, and a second spring is provided between one end of the second slide groove and the transmission rod.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0012] The glue cartridge is placed into the first housing. Once the piston aligns with the cartridge, the drive motor is activated. The drive motor rotates the drive bevel gear, which in turn rotates the driven bevel gear. The driven bevel gear, via the third rotating shaft, rotates the limiting post. The limiting post rotates the second rotating shaft, which in turn rotates the second gear. The second gear then rotates the first gear. The second and first gears move the two push rods within the first housing, squeezing the glue cartridge and dispensing glue. After the glue in the cartridge is cleared, the push rods continue to move, bringing the distance between the second and first magnets closer until the pushing force of the second magnet on the first magnet exceeds the elastic force of the second spring. At this point, the second adjusting rod separates from the first groove, and the second limiting plate is lifted by the elastic force of the first spring. The driven bevel gear then separates from the drive bevel gear, and the push rods stop moving. This prevents damage to the internal parts of the glue gun due to overload, thus extending the glue gun's lifespan. Attached Figure Description

[0024] Specifically, such as Figure 3 and Figure 4 As shown, the gear transmission unit includes a first gear 12 and a second gear 13, which are meshed together. The first gear 12 meshes with a toothed plate 8, and the second gear 13 meshes with another toothed plate 8. A first rotating shaft 14 is provided at the bottom of the first gear 12, and the first rotating shaft 14 is rotatably connected to a second housing 2. A second rotating shaft 15 is provided at the bottom of the second gear 13, and the second rotating shaft 15 is rotatably connected to the second housing 2. A first limiting plate 16 is provided between the first rotating shaft 14 and the second rotating shaft 15, and the first rotating shaft 14 and the second rotating shaft 15 are respectively connected to the first limiting plate 16. 6. A rotatable connection is provided. A transmission mechanism that drives the first rotating shaft 14 to rotate is provided inside the third housing 3. The transmission mechanism is provided with a drive motor 20 inside the third housing 3. A drive bevel gear 21 is provided at the output end of the drive motor 20. A second limiting plate 23 is provided on the inner wall of the third housing 3. A third rotating shaft 18 is rotatably connected to the second limiting plate 23. A driven bevel gear 19 that meshes with the drive bevel gear 21 is provided at one end of the third rotating shaft 18. A limiting post 17 is provided at the other end of the third rotating shaft 18. A limiting hole 22 is opened at the bottom of the first rotating shaft 14. The limiting post 17 and the limiting hole 22 are slidably connected.

[0025] Specifically, such as Figure 5 As shown, a strip-shaped hole 34 is provided on the upper part of the third housing 3, and a first sliding rod 24 is provided in the strip-shaped hole 34. The second limiting plate 23 is slidably connected to the first sliding rod 24. A support plate 25 is provided on the side of the third housing 3, and a first spring 26 is provided between the support plate 25 and the second limiting plate 23. A second sliding groove 31 is provided on the side of the third housing 3, and a transmission rod 29 is slidably connected in the second sliding groove 31.

A first sliding groove 27 is provided on the upper end face of the second limiting plate 23, and the second adjusting rod 28 is slidably connected to the first sliding groove 27.

[0026] Specifically, such as Figure 4 and Figure 5As shown, a first limiting rod 10 is provided at one end of the transmission plate 9, a first adjusting rod 11 is provided at the bottom of the first limiting rod 10, a second magnet 35 is provided at the end of the first adjusting rod 11, a first magnet 30 is provided on the side of the transmission rod 29, the magnetic poles of the first magnet 30 and the second magnet 35 are opposite on opposite sides, a second sliding rod 32 is provided in the second sliding groove 31, the second sliding rod 32 is slidably connected to the transmission rod 29, and a second spring 33 is provided between one end of the second sliding groove 31 and the transmission rod 29.

[0027] In summary, the dual-component gear-driven electric glue gun provided in this embodiment operates by placing the glue cartridge into the first housing 1. Once the piston 7 aligns with the glue cartridge, the drive motor 20 is activated. The drive motor 20 drives the drive bevel gear 21 to rotate, which in turn drives the driven bevel gear 19 to rotate. The driven bevel gear 19, via the third rotating shaft 18, drives the limiting post 17 to rotate. The limiting post 17 drives the second rotating shaft 15 to rotate, which in turn drives the second gear 13 to rotate. The second gear 13 then drives the first gear 12 to rotate, and the second gear 13 and the first gear 12 together drive... Two push rods 6 move within the first housing 1, squeezing the glue cartridge and dispensing glue. Once the glue in the cartridge is cleared, as the push rods 6 continue to move, the distance between the second magnet 35 and the first magnet 30 gets closer and closer until the pushing force of the second magnet 35 on the first magnet 30 exceeds the elastic force of the second spring 33. At this point, the second adjusting rod 28 separates from the first slide groove 27, and the second limiting plate 23 is lifted by the elastic force of the first spring 26. At this time, the driven bevel gear 19 separates from the driving bevel gear 21, and the push rods 6 stop moving. This prevents the internal parts of the glue gun from being damaged due to overload.
