The bottom end of the hot melt glue machine body is provided with a nozzle fixing seat, and the inner wall of the nozzle fixing seat is threaded. A support column is provided on the outer wall of the hot melt glue machine body. A motor is detachably provided on the inner top wall of the support column. The output end of the motor is locked with a lead screw through a coupling. A connecting block is threaded on the outer wall of the lead screw. A connecting rod is provided at the bottom end of the connecting block. The bottom end of the connecting rod extends out of the support column and is detachably provided with a second motor.

[0004] The aforementioned patents or existing nozzle devices have the following problems:

[0005] Existing nozzle devices require cleaning after use, and nozzles need to be disassembled if blockage occurs. However, existing nozzle connections use threaded connections, which are inconvenient for subsequent disassembly and maintenance. Utility Model Content

[0006] The purpose of this invention is to provide a nozzle device for a hot melt adhesive machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a nozzle device for a hot melt adhesive machine, comprising a fixed base, a mounting bracket provided on the surface of the fixed base, a connector provided on the surface of the fixed base, a nozzle provided at the lower end of the fixed base, a limiting structure provided at the lower end of the fixed base, the limiting structure comprising a connecting base, a connecting base provided at the lower end of the fixed base, a fixing plate provided in the connecting base, a spring fixed on the surface of the fixing plate, a clamp provided on the surface of the fixing plate, a rotating ring connected in the connecting base, a push block provided on the surface of the rotating ring, and a slot provided on the surface of the nozzle.

[0008] Preferably, the connector surface is provided with a positioning block.

[0009] Preferably, when the positioning block is inserted into the connecting seat, the bayonet and the bayonet head are on the same vertical upper line.

[0010] Preferably, the connecting seat is equipped with a sealing ring inside, and a positioning head is provided on the surface of the sealing ring.

[0011] Preferably, the pusher block has a groove.

[0012] Preferably, the rotating ring surface is provided with a handle.

[0013] Preferably, the handle is provided with a locking structure, the locking structure includes a second spring, the second spring is fixed in the handle, the second spring is provided with a locking rod, the surface of the locking rod is fixed with a connecting plate, and the surface of the connecting seat is provided with a notch.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the nozzle is aligned with the connector, the positioning block inserts into the connector. Continuously pushing the nozzle presses the sealing ring between the nozzle and the connector to achieve a seal. Rotating the rotating ring drives the push block, which pushes the locking head, causing it to engage in the slot and limit the nozzle's installation. Under the action of the second spring, the locking rod inserts into the recess to lock in place, thus facilitating easy nozzle installation. To disassemble, pull the locking rod to slide it out of the recess, then rotate the rotating ring by the handle, which drives the push block. Under the action of the spring, the locking head slides out of the slot, releasing the nozzle's restriction and facilitating easy disassembly. Attached Figure Description

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 and Figure 2This utility model provides a nozzle device for a hot melt glue machine, including a fixed base 1, a mounting bracket 2 fixed to the surface of the fixed base 1 by bolts, a connector 3 provided on the surface of the fixed base 1, a nozzle 4 provided at the lower end of the fixed base 1, and a limiting structure 5 provided at the lower end of the fixed base 1.

[0023] Specifically, the mounting bracket 2 is fixed to the hot melt glue machine with screws, and the glue tube of the hot melt glue machine is connected to the connector 3. The hot melt glue machine injects hot melt glue into the mounting base 1 through the glue tube and connector 3, and then sprays glue through the nozzle 4.

[0024] Please see Figure 2 , Figure 3 and Figure 4 This utility model provides a nozzle device for a hot melt glue machine. The limiting structure 5 includes a connecting seat 51. The connecting seat 51 is installed at the lower end of the fixed seat 1 and communicates with the fixed seat 1. A fixed plate 52 is fixed in the connecting seat 51. A spring 53 is fixed on the surface of the fixed plate 52. A clamp 54 is provided on the surface of the fixed plate 52. The clamp 54 is slidably connected to the fixed plate 52, and one end of the spring 53 is fixed to the inner side of the clamp 54. A rotating ring 55 is rotatably connected in the connecting seat 51. A push block 56 is integrally formed on the surface of the rotating ring 55, and a groove 561 is provided in the push block 56. The clamp 54 is located in the groove 561. A slot 57 is provided on the surface of the nozzle 4, and a positioning block 501 is provided on the surface of the connector 3. When the positioning block 501 is inserted into the connecting seat 51, the slot 57 and the clamp 54 are on the same vertical line, which improves the convenience of installation.

[0025] The connecting seat 51 is equipped with a sealing ring 58, and the surface of the sealing ring 58 is provided with a positioning head 59. The positioning head 59 is locked in the connecting seat 51, which ensures the stability of the installation of the sealing ring 58 and prevents the sealing ring 58 from falling out after the connector 3 is removed.

[0026] The rotating ring 55 has a handle 510 on its surface to facilitate rotation of the rotating ring 55. The handle 510 has a locking structure 511, which includes a second spring 5111. The second spring 5111 is fixed in the handle 510. The second spring 5111 has a locking rod 5112 in its surface. The locking rod 5112 has a connecting plate 5113 fixed on its surface. The connecting plate 5113 is fixed to one end of the second spring 5111. The connecting seat 51 has a notch 5114 on its surface.

[0027] Specifically, the nozzle 4 is aligned with the connecting seat 51. The positioning block 501 is inserted into the connecting seat 51, continuously pushing the nozzle 4 to press against the sealing ring 58. The sealing ring 58 fills the space between the nozzle 4 and the connecting seat 51 to achieve a seal. At the same time, the bayonet 57 aligns with the bayonet 54. Then, rotating the rotating ring 55 drives the push block 56 to rotate clockwise. The rotating push block 56 pushes the bayonet 54, causing it to slide along the surface of the fixing plate 52. At this time, the spring 53 is stretched and generates elastic force, and the bayonet 54 will engage in the bayonet 57, thereby limiting the installation of the nozzle 4. After the clip 54 is inserted into the slot 57, the locking rod 5112 will be aligned with the notch 5114. Under the action of the second spring 5111, the connecting plate 5113 will be pushed, causing the locking rod 5112 to be inserted into the notch 5114 for locking, so as to achieve the beneficial effect of easy installation of the nozzle 4. When disassembling, pull the locking rod 5112 to slide it out of the notch 5114. Then, rotate the rotating ring 55 by the handle 510, which will drive the push block 56. Under the action of the spring 53, the push block 56 rotates, and the clip 54 slides out of the slot 57, releasing the restriction on the nozzle 4, so as to achieve the beneficial effect of easy disassembly.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
