Description

Technical Field

[0001] This utility model relates to the field of constant temperature adhesives, and in particular to a constant temperature adhesive output mechanism. Background Technology

[0002] A common thermostatic adhesive output mechanism is the hot melt adhesive spray valve, a device used to precisely control the spray flow and spraying pattern of hot melt adhesive. It is widely used in automated production lines in industries such as packaging, electronics, automobiles, and home furnishings. Its working principle is to heat the solid hot melt adhesive to a molten state through a heating system, and then spray the molten adhesive at a precise flow rate through the spray valve to complete functions such as bonding, sealing, or fixing of object surfaces. The hot melt adhesive spray valve consists of a heater, nozzle, and control system. The heater ensures the temperature and fluidity of the hot melt adhesive, while the nozzle controls the spraying method and spraying range of the adhesive.

[0003] The main advantages of hot melt adhesive spray valves are their high spraying precision and fast response speed, enabling efficient and uniform hot melt adhesive coating. Through the precise control of spraying timing, flow rate and spraying angle by the CNC system, they can meet the needs of different production processes and are particularly suitable for automated and mass production. Common application scenarios include packaging box sealing, electronic component bonding, and automotive part fixing.

[0004] During use, the hot melt adhesive spray valve moves flexibly in conjunction with a lathe, enabling it to reach designated application points. However, to prevent the adhesive from solidifying internally and causing malfunctions when the hot melt adhesive spray valve is stopped, the adhesive delivery pipe must be disassembled and the inside of the hot melt adhesive spray valve cleaned after each use. In traditional hot melt adhesive spray valves, the connection between the delivery pipe and the hot melt adhesive spray valve is fixed by clamps, requiring bolt tightening for each disassembly and reassembly, which is time-consuming and labor-intensive and cannot achieve quick disassembly and reassembly. Therefore, a constant temperature adhesive output mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a constant temperature glue output mechanism, which aims to improve the traditional hot melt glue spray valve. The connection between the delivery pipe and the hot melt glue spray valve is fixed by clamps, which requires tightening bolts every time it is disassembled and assembled, which is time-consuming and laborious and cannot achieve quick disassembly and assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a constant temperature glue output mechanism, including a constant temperature tank, a nozzle fixedly connected to the bottom of the constant temperature tank, a conveying pipe slidably connected to the top of the constant temperature tank, a splicing component installed on the top of the constant temperature tank, and a fixing component installed on the rear side of the constant temperature tank;

[0007] The splicing assembly includes a fixing ring, the inner side of which is fixedly connected to the top of the constant temperature tank. A rotating ring is rotatably connected to the outside of the fixing ring. Four ropes are fixedly connected to the inside of the rotating ring. A spring is sleeved on the outside of each rope. A sliding plate is fixedly connected to the inside of the spring. A fixing bolt is fixedly connected to the inside of the sliding plate.

[0008] As a further description of the above technical solution:

[0009] The fixing assembly includes four housings. The outer side of each housing is slidably connected to the inside of the constant temperature tank. A push rod is slidably connected inside each housing. A slide plate is fixedly connected to the rear end of each push rod. A spring is fixedly connected to the rear side of the slide plate. A rotating block is fixedly connected to the rear side of each push rod. Four connecting rods are rotatably connected to the outside of each rotating block. A baffle is rotatably connected to the outer side of each connecting rod. A lathe slide plate is fixedly connected between the rear sides of the four housings.

[0010] As a further description of the above technical solution:

[0011] The rope is externally slidably connected inside the fixed ring, and the inner side of the rope is fixedly connected to the outside of the slide plate.

[0012] As a further description of the above technical solution:

[0013] The outer side of the spring is fixedly connected to the inner wall of the fixed ring, and the outer side of the slide plate is slidably connected to the inner wall of the fixed ring.

[0014] As a further description of the above technical solution:

[0015] The fixing bolt is externally slidably connected inside the fixing ring, externally slidably connected inside the constant temperature tank, and externally inserted into the delivery pipe.

[0016] As a further description of the above technical solution:

[0017] The baffle is slidably connected to the outside of the housing, and the rear side of the baffle is slidably connected to the front side of the constant temperature tank.

[0018] As a further description of the above technical solution:

[0019] The outer wall of the slide plate is slidably connected to the inner wall of the casing.

[0020] As a further description of the above technical solution:

[0021] The rear end of the second spring is fixedly connected to the inner wall of the housing, and the rear side of the rotating block is fixedly connected to the front side of the second sliding plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by rotating the rotating ring, the rope pulls the slide plate and compresses the spring, while the fixing bolt is retracted into the fixing ring, which enables the delivery pipe to be quickly pulled out of the constant temperature tank, making it convenient to clean the constant temperature tank and preventing the glue from solidifying when the machine is stopped, thus affecting normal use.

[0024] 2. In this utility model, by pressing the push rod, the slide plate two compresses the spring two, and at the same time the rotating block starts to pull the connecting rod to move the baffle into the housing. At this time, the thermostatic tank is inserted into the outside of the housing and the push rod is released, so that the baffle pops out. This realizes the quick installation and disassembly of the thermostatic tank, and facilitates the replacement of thermostatic tanks and nozzles for different purposes. Attached Figure Description

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.

[0033] Reference Figure 1 - Figure 4An embodiment of this utility model is provided: a constant temperature glue output mechanism, including a constant temperature tank 1, a nozzle 17 fixedly connected to the bottom of the constant temperature tank 1, and a conveying pipe 2 slidably connected to the top of the constant temperature tank 1. The constant temperature tank 1 is used to heat and keep the glue warm to prevent the glue from solidifying. The nozzle 17 is used to spray the glue out. The conveying pipe 2 is used to transport the glue into the constant temperature tank 1. A splicing component is installed on the top of the constant temperature tank 1, and a fixing component is installed on the rear side of the constant temperature tank 1.

[0034] The assembly includes a fixing ring 3, which is fixedly connected to the top of the constant temperature tank 1. A rotating ring 4 is rotatably connected to the outside of the fixing ring 3. Four ropes 5 are fixedly connected to the inside of the rotating ring 4. Springs 6 are sleeved on the outside of the ropes 5. A sliding plate 7 is fixedly connected to the inside of the springs 6. A fixing bolt 8 is fixedly connected to the inside of the sliding plate 7. The fixing ring 3 is used to connect and limit other parts. The rotating ring 4 encloses the fixing ring 3 and is connected to the ropes 5 for easy rotation. The ropes 5 are used to pull the sliding plate 7 to move. The springs 6 are used to allow the sliding plate 7 to automatically return to its original position. The fixing bolt 8, limited by the fixing ring 3, can only move in a specified direction and will not move or wobble. The sliding plate 7 is fixed to its outside to prevent the fixing bolt 8 from moving. If the movement exceeds the range, it may detach. The fixing bolt 8 is used to fix the delivery pipe 2 inside the constant temperature tank 1 for easy disassembly and assembly. The rope 5 is externally slidably connected to the inside of the fixing ring 3. The inner side of the rope 5 is fixedly connected to the outside of the slide plate 7, so that when the rotating ring 4 is rotated, the rope 5 can pull the fixing bolt 8 to move. The outer side of the spring 6 is fixedly connected to the inner wall of the fixing ring 3 to keep the spring 6 stable. The outer side of the slide plate 7 is externally slidably connected to the inner wall of the fixing ring 3. The fixing bolt 8 is externally slidably connected to the inside of the fixing ring 3. The fixing ring 3 simultaneously restricts the movement direction of the slide plate 7 and the fixing bolt 8. The outer side of the fixing bolt 8 is externally slidably connected to the inside of the constant temperature tank 1 to restrict the movement direction of the fixing bolt 8. The outer side of the fixing bolt 8 is inserted into the inside of the delivery pipe 2 to achieve fixation.

[0035] Reference Figure 1 , Figure 5The fixing assembly includes four housings 9, which are externally slidably connected to the inside of the constant temperature tank 1. A push rod 10 is slidably connected inside each housing 9. A slide plate 11 is fixedly connected to the rear end of the push rod 10. A spring 12 is fixedly connected to the rear side of the slide plate 11. A rotating block 13 is fixedly connected to the rear side of the push rod 10. Four connecting rods 14 are rotatably connected to the outside of the rotating block 13. A baffle 15 is rotatably connected to the outer side of each connecting rod 14. A lathe slide plate 16 is fixedly connected between the rear sides of the four housings 9. The housings 9 are used to connect and protect the internal parts. The push rod 10 drives the slide plate 11 to compress the spring 12, thereby moving the baffle 15. The slide plate 11 compresses the spring 12 and bears the thrust from the spring 12. The spring 12 is used to... The sliding plate 11 is reset to extend the baffle 15. The fixed rotating block 13 is used to drive the connecting rod 14 to deflect, so that the baffle 15 moves. The baffle 15 is used to block the constant temperature tank 1 and achieve installation and fixation. The lathe sliding plate 16 is used to drive the nozzle 17 to move freely on the plane. The baffle 15 is externally slidably connected to the inside of the housing 9 to limit the movement direction of the baffle 15. The rear side of the baffle 15 is slidably connected to the front side of the constant temperature tank 1 to achieve installation and fixation. The outer wall of the sliding plate 11 is slidably connected to the inner wall of the housing 9 to limit the movement direction of the sliding plate 11. The rear end of the spring 12 is fixedly connected to the inner wall of the housing 9 to keep the spring 12 stable. The rear side of the rotating block 13 is fixedly connected to the front side of the sliding plate 11 to make the sliding plate 11 and the rotating block 13 move synchronously.

[0036] Working Principle: When using this device, the glue is delivered to the thermostatic tank 1 through the delivery pipe 2. The thermostatic tank 1 maintains a constant temperature, keeping the glue in a liquid state. Combined with the movement of the lathe slide plate 16, the nozzle 17 sprays the glue onto the designated location. After work is completed, the thermostatic tank 1 needs to be cleaned promptly. By rotating the rotating ring 4, the rope 5 pulls the slide plate 7, compressing the spring 6, causing the fixing bolt 8 to retract into the fixing ring 3 and disengage from the delivery pipe 2. Then, the delivery pipe 2 is pulled out of the thermostatic tank 1 and cleaned to prevent the glue from solidifying. After cleaning, the delivery pipe 2 is reinserted into the thermostatic tank 1. At this point, the rotating ring 4 is released. Under the limit of the fixing ring 3, the spring 6 immediately pushes the slide plate 7, causing the fixing bolt 8 to retract into the fixing ring 3 and disengage from the delivery pipe 2. When the fixed bolt 8 is pushed out, it is inserted into the delivery pipe 2, fixing the delivery pipe 2 and enabling quick disassembly and assembly. When it is necessary to replace the constant temperature tank 1 and the nozzle 17 with different functions, by pressing the push rod 10, the slide plate 2 11 is driven to compress the spring 2 12, causing the rotating block 13 to drive the connecting rod 14 to pull the baffle 15, which is then retracted into the housing 9. Then, the constant temperature tank 1 is taken out from the lathe slide plate 16 and the required constant temperature tank 1 and nozzle 17 are placed on it. At this time, the push rod 10 is released, and the slide plate 2 11 is pushed under the action of the spring 2 12, causing the push rod 10 to return to its original position. The rotating block 13 drives the connecting rod 14 to push out and unfold the baffle 15, which blocks the front side of the constant temperature tank 1, thus achieving installation and fixation. This saves time and effort and effectively improves replacement efficiency.
