Detailed Implementation

[0026] In this embodiment, as Figures 1-7 The dispensing gun holder shown includes a first slide rail 1, a first slider 2, a drive cylinder 5, and a dispensing gun 7. The first slider 2 is slidably mounted on the first slide rail 1. The drive cylinder 5 and the dispensing gun 7 are both mounted on the first slider 2. The drive cylinder 5 is used to drive the movement of the dispensing gun 7. The drive cylinder 5 includes a housing 51, a piston rod 53, and a connector 54. The inner cavity of the housing 51 is a stepped hole 511, and the connector 54 is connected to a compressed air source. The piston rod 53 is movably mounted in the stepped hole 511. One end of the piston rod 53 passes through the housing 51 and is connected to the dispensing gun 7. The other end of the housing 51 is connected to the connector 54. A spring 55 is sleeved on the piston rod 53. One end of the spring 55 abuts against the end wall of the stepped hole 511, and the other end abuts against the piston head 531 of the piston rod 53. By opening a stepped hole 511 in the housing 51 of the drive cylinder 5, during installation, the spring 55 is installed in the small diameter section of the stepped hole 511, one end of the piston rod 53 passes through the spring 55, and the piston head 531 at the other end of the piston rod 53 is located in the large diameter section of the stepped hole 511. During use, when the compressed air from the connector 54 pushes the piston rod 53 to move, the spring 55 provides a buffering effect on the piston rod 53, making the movement of the piston rod 53 more stable. At the same time, the elasticity of the spring 55 can effectively prevent the piston head 531 from directly impacting the end wall of the inner cavity of the housing 51 under the action of compressed air. This can effectively solve the problem of vibration that is easily caused when the drive cylinder 5 moves, and ensure the accuracy of drip molding.

[0027] In this embodiment, when the compressed air is disconnected at the connector 54, the spring force of the spring 55 pushes the piston rod 53 to automatically return to the initial position.

[0028] In the embodiment, the first slider 2 is installed on the top surface of the first sliding rail 1, and mounting clamping grooves 11 are arranged on both sides of the first sliding rail 1, and the LED decorative lamp is installed in the mounting clamping grooves 11. When the utility model is installed, the gun head of the glue dispensing gun 7 is usually downward (as shown in Figure 2 The LED decorative lamp can display different colors, and the color of the LED decorative lamp can be set to be consistent with the color of the pigment in the glue dispensing gun 7, thereby facilitating the operation of the user.

[0029] Specifically, as shown in Figure 1 and Figure 2 , the first slider 2 is provided with a mounting seat 3 on the top surface, one end of the mounting seat 3 is provided with a second sliding rail 4, and the other end is provided with a vertical mounting plate; the housing 51 of the driving cylinder 5 is fixedly installed on the vertical mounting plate; a second slider 41 is installed on the second sliding rail 4 in a slidable manner, the piston rod 53 of the driving cylinder 5 is connected with the second slider 41, and the glue dispensing gun 7 is installed on the second slider 41. The glue dispensing gun seat 6 is installed on the second slider 41, and the glue dispensing gun 7 is installed in the glue dispensing gun seat 6.

[0030] In the embodiment, the specific structure of the first slider 2, the first sliding rail 1, the second sliding rail 4, the second slider 41, the glue dispensing gun seat 6 and the glue dispensing gun 7 can refer to the utility model patent with the patent number ZL202321840442.8, and details are not repeated here.

[0031] In the embodiment, the piston head 531 of the piston rod 53 includes two annular plates, and a sealing ring 533 is arranged between the two annular plates. At the same time, the piston head 531 is provided with a sealing ring 533 on the side close to the spring 55. The sealing ring 533 arranged between the two annular plates can effectively seal the side wall of the large diameter section of the stepped hole 511, so that when the connecting head 54 inputs compressed air, the compressed air can effectively push the piston head 53 to move towards the small diameter section. When the compressed air completely compresses the spring 55 to the small diameter section, the piston head 53 will abut against the end wall of the large diameter section of the stepped hole 511, and the sealing ring 533 arranged between the annular plate close to the spring 55 and the spring 55 can effectively buffer the contact between the piston head 53 and the housing 51 while playing a sealing role.

[0032] In the embodiment, as shown in Figure 3 and Figure 7 , the end of the piston rod 53 away from the piston head 531 is provided with an annular clamping groove 532. The end of the second slider 41 close to the driving cylinder 5 is provided with a clamping opening, and when connected, the annular clamping groove 532 on the piston rod 53 is directly clamped in the clamping opening of the second slider 41 (as shown in Figure 8 ), so that the piston rod 53 drives the second slider 41 to move synchronously.

[0033] In the embodiment, as shown in Figure 4As shown, the stepped hole in the shell 51 is a three-step stepped hole. The three-step stepped hole includes a small-diameter section where the spring 55 is located, a large-diameter section where the piston head 531 is located, and a transition section which is penetrated by the piston rod 53, and the outer wall of the transition section is screwed with the end cover 52.
