Description

Technical Field

[0001] The invention relates to the technical field of glue injection equipment, in particular to a plug metering glue injection device. Background Art

[0002] At present, most of the glue injection devices are for single glue injection. After some glue is mixed, its performance will be better than that of single glue. Therefore, a glue mixing device capable of mixing glue is needed. Different glues can be well mixed through the glue mixing device, and the mixed glue can be discharged. However, if glue mixing is needed in the process of glue injection, a glue mixing chamber will be needed. In most of the current products, the handling of the glue mixing chamber and the glue outlet pipe is the most troublesome. As for the handling of the glue mixing chamber and the glue outlet pipe, the current method is to disassemble and clean them, which needs to waste more manpower and material resources, so the efficiency is low and it is not suitable for a large number of glue discharge processes.

[0003] The prior art also has the following defects during use: In order to improve the performance of glue, it may be necessary to mix the glue in some cases. During the mixing process, some glue will remain in the mixing chamber. If the glue remaining in the mixing chamber cannot be discharged, it will solidify inside after a period of time. After solidification, subsequent internal mixing cannot be carried out. In addition, glue will inevitably remain on the inner wall of the glue outlet pipe during the glue discharge process, which will cause the thickness of the inner wall to change. If the inner wall is too thick, the space of the through pipe will become thinner, which will increase the dispensing speed and cause inaccurate dispensing. In addition, various dispensing devices are currently unable to perform accurate dispensing during the dispensing process, and the dispensing is prone to overflow or insufficient. In either case, it will have an adverse effect on the production process.

[0004] Although the existing glue injection device has a glue discharge structure, which discharges the glue in the glue injection tube through a guide rod, the inner cavity of the glue injection tube is relatively thin and the length of the glue injection tube is too long. The straight rod structure easily causes the guide rod to be compressed and deformed, and the glue discharge device often fails to operate due to the deformation of the guide rod.

[0005] In view of this, we propose a plug metering glue injection device to solve the existing problems. Summary of the invention

[0008] Furthermore, a permanent magnet is fixedly mounted on the connection surface between the medium cavity and the second row of rubber blocks, and the permanent magnet is adsorbed and connected to the upper end surface of the third row of rubber blocks.

[0009] Furthermore, a plurality of cylinders are installed on the upper end of the flow tube mounting plate, the inner sides of the cylinders are respectively provided with a first inner cavity and a second inner cavity, the upper ends of the cylinders are connected to piston rods, and the upper ends of the piston rods are connected to piston rod pressure blocks.

[0010] Furthermore, a first glue inlet and a second glue inlet are provided on both sides of the flow tube mounting plate, and accelerated glue feed pumps are installed on both sides of the flow tube mounting plate, and the accelerated glue feed pumps are connected to the first glue inlet and the second glue inlet.

[0011] Furthermore, the first inner cavity is downwardly connected to a first rubber hose, the second inner cavity is downwardly connected to a second rubber hose, and a plurality of groups of mixing rubber cavities are installed on the flow tube mounting plate, and the upper ends of the mixing rubber cavities are connected to the first rubber hose and the second rubber hose.

[0012] Furthermore, the glue storage cavity is installed at the center of the lower end of the flow tube mounting plate, and both sides of the upper end of the glue storage cavity are connected to the glue mixing cavity.

[0013] Furthermore, the first glue inlet is communicated with the first inner cavity, and the second glue inlet is communicated with the second inner cavity.

[0014] Furthermore, the lower end of the third row of rubber blocks is conical, the upper end of the third row of rubber blocks perfectly matches the inner wall of the rubber outlet pipe, the lower end of the third row of rubber blocks is of the same size as the head of the rubber outlet pipe, and a stepped guide head is provided at the upper end of the third row of rubber blocks.

[0015] Furthermore, the debonding surfaces of the first row of debonding blocks, the second row of debonding blocks and the third row of debonding blocks are all made of polytetrafluoroethylene material.

[0016] Furthermore, a method for using the plug metering glue injection device comprises the steps of: S1 discharges glue A into the first inner cavity through the first glue inlet, and discharges glue B into the second inner cavity through the second glue inlet, and drives the piston rod downward through the piston rod pressure block to squeeze glue A and glue B into the first rubber hose of the array and the second rubber hose of the array; S2 discharges glue A and glue B into the glue mixing chamber through the first and second glue hoses at the same time, and drives the spiral rod to rotate through a small motor. At the same time, the first row of glue blocks begins to move downward under the action of the limit groove and the spiral rod, mixing glue A and glue B, and discharging the AB mixed glue into the glue storage chamber below through the first row of glue blocks; The S3 drive motor starts, driving the rotating shaft to start moving, and then the first rotating rod moves downward together. The first rotating rod drives the second row of rubber blocks downward to discharge the glue in the rubber storage chamber into the rubber outlet pipe. When the glue enters the rubber outlet pipe, the first rotating rod and the second row of rubber blocks stop moving downward, and the medium booster device works to discharge the medium into the medium chamber through the medium inlet. The third row of rubber blocks continues to discharge the glue in the rubber outlet pipe under the pressure of the medium until the corresponding amount is discharged or the glue is completely drained. Then the medium booster device recovers the medium to make the third row of rubber blocks return to their original position under the tension of the elastic connecting rope, and the permanent magnet is used to limit and position the third row of rubber blocks.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a glue mixing chamber in the glue injection device, and mixes different types of glue through the spiral rod structure in the glue mixing chamber. Two groups of different glues start to move with the rotation of the spiral rod. In the process of continuous rotation, the two groups of different glues are fused. When the spiral rod is started and drives the glue mixing, the glue discharge block located at the upper end of the spiral rod begins to move downward under the action of the spiral rod and the front and rear limit grooves. The glue discharge block is in close contact with the inner wall of the glue mixing chamber and the spiral rod. During the movement, the residual glue in the glue mixing chamber is completely discharged into the glue outlet pipe, which can effectively avoid residual glue residue, and the glue mixing chamber can realize preliminary control of the glue injection amount. A glue storage chamber is provided at the upper end of the glue outlet pipe, and a second row of glue blocks and a third row of glue blocks are installed on the upper end of the glue storage chamber. The two groups of glue discharge blocks can respectively control the glue in the glue storage pipe and the glue outlet pipe. Further discharge can effectively and completely discharge the glue in the glue storage chamber and the glue outlet pipe, and this group of glue discharge blocks can control the amount of glue discharge more finely, so that in the production process, the amount of glue can be better controlled. The overall device can effectively ensure the long-term use of the glue injection device, avoid residual glue remaining inside, and improve the control of the amount of glue, making the overall glue dispensing more precise, and achieving better glue dispensing effect in the production process. The combination of multiple groups of glue discharge block structures can effectively drain the glue in the glue injection device and effectively avoid glue retention, ensuring the cleanliness of various parts inside the glue injection device and avoiding the influence of glue retention on subsequent work; glue injection heads are respectively provided on both sides, which can adjust the amount of mixed glue injected according to needs, and multiple groups of glue injection heads and glue mixing chambers can increase the capacity of glue and increase more glue discharge.

[0018] At the same time, the third row of rubber blocks is pushed by applying pressure from the medium, which solves the problem of deformation of traditional guide rods under pressure due to their thin structure and long length, thereby improving the service life of the rubber removal device.
