Detailed Description

The invention is described in detail with reference to the accompanying drawings, as shown in fig. 1-3, a glue chamber 2 is arranged on a frame 1, and a cavity 18 of the glue chamber is respectively connected with a glue inlet valve 3 and a glue outlet valve 4; a valve body 17 is arranged in the cavity 18, one end of the valve body 17 is connected with the piston rod 9, and the upper end of the piston rod 9 is connected with the output end of the linear motor 8; the rubber chamber 2 is fixedly connected with the lower guide seat 19 through a screw, and two ends of the guide rod 10 penetrate through guide holes of the upper guide seat 13 and the lower guide seat 19; the upper guide seat 13 and the lower guide seat 19 are fixed on the frame 1; the linear motor 8 is connected with the servo driver 7; the glue inlet valve 3 is connected with a glue pump 11, and the glue pump 11 is connected with a glue storage tank 12.

The valve body 17 is accurately positioned during working, and the glue conveying amount and the glue conveying speed are directly related, so that in order to accurately control the working position of the valve body and prevent the valve body from slightly deviating under the action of the piston rod, the guide structure can be also shown in figure 1, the lower end of the guide rod 10 is fixed with the valve body 17, and after the guide rod 10 passes through the upper end of the glue chamber, the upper end of the guide rod passes through the positioning hole of the upper guide seat and/or the lower guide seat; owing to adopt 3 at least guide bars (this embodiment can adopt 4), consequently, to the valve body, adopt the multiple spot location, it is better to eccentric, the skew control of valve body, consequently, the location effect of this structure is better, but need make the sliding seal between guide bar and the gluey room, can adopt the seal cover to solve this problem.

For accurate positioning, the piston rod 9 is sleeved in the guide holes of the upper guide seat 13 and the lower guide seat.

In order to ensure the synchronism of the guide rod 10, one end of the guide rod 10, which is exposed out of the glue chamber, is fixed with the connecting block 6, and the connecting block is fixed with the piston rod.

The glue inlet valve and the glue outlet valve can adopt electromagnetic or mechanical types; when the mechanical type is adopted, the glue inlet valve and the glue outlet valve are both provided with driving cylinders, and the driving cylinders are connected with the control center. The control center is an upper computer which is respectively connected with the servo controller and a gas control valve of the cylinder;

glue the room, go into gluey valve and go out gluey valve and all install heating original paper and temperature-detecting element, realize temperature automatic control, can heat the colloid to the technology setting value and keep warm, its effect as follows.

Firstly, the solidification of the colloid is avoided; secondly, the fluidity of the colloid is enhanced; setting the fixed temperature according to the characteristics of the colloid so as to achieve the best adhesive effect of the colloid.

The concrete structure is as follows: and heating devices 5 are arranged outside the glue chamber, the glue inlet valve and the glue outlet valve, and can be resistance wires or PTC heaters and the like.

Thermometers are arranged outside the glue chamber, the glue inlet valve and the glue outlet valve.

The working principle of the invention is as follows:

the glue pump is started, glue is pumped, the glue inlet valve is opened, the glue outlet valve is closed, the linear motor drives the piston rod to return, and meanwhile, whether the glue amount in the glue chamber reaches a set value or not is monitored in real time through the servo controller. If the glue amount in the pectin chamber reaches a set value, the glue inlet valve is closed, the linear motor stops driving the piston rod to return, and the glue injection process is completed.

The gluing application process is as follows:

1. generating pre-pressing:

firstly, both the glue outlet valve and the glue inlet valve are closed.

Secondly, the linear motor drives the piston rod to generate thrust, and a pre-pressing set state is achieved.
