[0019] The following specific examples illustrate the embodiments of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0020] The following will further elaborate on the present utility model in conjunction with the attached Figure 1 Drawings.

[0021] An embodiment of the present utility model discloses a synchronous pressurization device for a glue application device.

[0022] Refer to Figure 1, A synchronous boosting device of a glue - applying device includes a connecting sleeve 5, a connecting joint 4 and a driving member. The connecting sleeve 5 has a discharging channel for the glue material to pass through. The connecting joint 4 has a feeding channel communicating with the discharging channel. A moving rod is arranged in the feeding channel. The driving member is used to drive the moving rod to slide axially in the feeding channel. During commutation, the driving member drives the moving rod to supplement the glue material in the feeding channel into the discharging channel. When the glue - applying device commutes, since it takes a certain time for the valve port to close, there is a certain fluctuation in the pressure of the glue material. By starting the driving member to supplement the glue material in the feeding channel into the discharging channel, the glue material can be supplemented in time, and the pressure fluctuation of the glue material is very small, making the overall glue discharge continuous and stable.

[0023] In this embodiment, the driving member is a cylinder 1, and the moving rod is the piston rod 2 of the cylinder 1. The piston rod 2 is slidably and fittingly installed in the feeding channel.

[0024] In this embodiment, the cylinder 1 is connected to the air source through a quick - connect fitting 7. Specifically, the cylinder 1 and the connecting joint 4 are fixed by a fixing member. The fixing member is a screw 6. A perforation is provided on the cylinder block of the cylinder 1. The screw 6 passes through the perforation of the cylinder block and is threadedly connected to the connecting joint 4, thereby installing the cylinder 1 on the connecting joint 4 to achieve detachable connection, which is convenient for the replacement and maintenance of the driving member in the later stage. Using compressed air as the power source, when compressed air enters the left end of the cylinder 1 of the device, the piston of the cylinder 1 pulls the piston rod 2 to move rightward to supplement the glue material in the feeding channel; when compressed air enters the right end of the cylinder 1, the piston of the cylinder 1 pushes the piston rod 2 to move leftward to push out the glue material in the feeding channel.

[0025] The axial direction of the discharging channel is perpendicular to the axial direction of the feeding channel, which makes it more smooth and convenient to supplement the glue material in the discharging channel and the glue material in the feeding channel.

[0026] A step is provided at one end of the feeding channel close to the driving member. A sealing ring 3 is arranged between the moving rod and the step. The setting of the sealing ring 3 improves the sealing performance of the feeding channel, effectively avoids the leakage of the glue material in the feeding channel and ensures that the glue material in the discharging channel can enter the feeding channel under the action of negative pressure.

[0027] The connecting joint 4 is threadedly connected to the connecting sleeve 5. Installing the connecting joint 4 on the connecting sleeve 5 through threaded connection not only has stable connection but also is convenient for disassembly in the later stage.

[0028] The cylinder 1 and the connecting joint 4 are fixed by four screws 6. The connecting joint 4 and the connecting sleeve 5 are threadedly connected. The piston rod 2 of the cylinder 1 has an interference fit with the sealing ring 3, and the glue material is sealed in the discharging channel of the connecting joint 4. The cylinder 1 and the quick - connect fitting 7 are threadedly connected.

[0029] When compressed air enters the left end of cylinder 1, the piston of cylinder 1 pulls the piston rod 2 to move rightward, forming a negative pressure to supplement the rubber material in the feeding channel of the connecting joint 4; when compressed air enters the right end of cylinder 1, the piston of cylinder 1 pushes the piston rod 2 to move leftward, pushing out the rubber material in the hole of the connecting joint 4 to supplement the rubber material in the discharging channel, making up for the problem of rubber discharging caused by the pressure fluctuation of the rubber material.

[0030] In this article, specific examples are used to elaborate on the principle and implementation mode of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. The above is only the preferred implementation mode of the present utility model. It should be noted that due to the limitation of literal expression and objectively there are infinite specific structures, for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements, retouches or changes can also be made, or the above technical features can be combined in an appropriate way; these improvements, retouches, changes or combinations, or directly applying the concept and technical solution of the utility model to other occasions without improvement, shall all be regarded as the protection scope of the present utility model.
