Description

Technical Field

[0001] The utility model relates to the field of glue dispensing valves, in particular to a glue dispensing valve capable of avoiding colloid residue in a pipeline. Background Art

[0002] The dispensing valve is used in the cover glue dispensing, color glue and bottom glue dispensing equipment in the lead-acid battery industry. It is also suitable for various precision dispensing instruments.

[0003] The existing dispensing valve controls the opening and closing of the air inlet pipe after the glue is fed in through the glue inlet pipe, thereby controlling the outflow of the glue from the glue outlet pipe. However, since the glue is adhesive and easy to solidify, when the glue flows through the glue inlet pipe and the glue outlet pipe, it is easy to remain in the pipe, causing the pipe to be blocked, which is quite inconvenient.

[0004] Therefore, a dispensing valve has been developed that uses Teflon coating to spray the two components of the rubber inlet pipe and the rubber outlet pipe, which is easy to clean and prevents the colloid from clogging and solidifying. At the same time, it can clean the colloid in the rubber outlet pipe to avoid colloid residue and can avoid colloid residue in the pipe. Utility Model Content

[0005] In order to overcome the disadvantages of existing dispensing valves that when colloid flows through the glue inlet pipe and the glue outlet pipe, it is easy to remain in the pipe, causing pipe blockage and being relatively inconvenient, the utility model provides a dispensing valve that uses Teflon coating to spray the two components of the glue inlet pipe and the glue outlet pipe, which is easy to clean and prevent the colloid from clogging and solidifying, and can also clean the colloid in the glue outlet pipe to avoid colloid residue, thereby avoiding colloid residue in the pipe.

[0006] The technical implementation scheme of the utility model is: a dispensing valve capable of avoiding colloid residue in the pipeline, comprising an air inlet pipe, a regulating valve, a dispensing body, a side air pipe, a glue inlet pipe, a glue outlet pipe and a cleaning mechanism, wherein the rear of the dispensing body is connected with the air inlet pipe, the air inlet pipe is rotatably connected with the regulating valve, the right side of the rear of the dispensing body is connected with the side air pipe, the left and right sides of the front of the dispensing body are connected with the glue inlet pipe, the front side of the dispensing body is connected with the glue outlet pipe, and the glue outlet pipe is provided with a cleaning mechanism capable of cleaning the colloid.

[0007] Furthermore, the cleaning mechanism includes a fixed rod, a rotating rod, an electric push rod and a water-absorbing sponge. The left part of the glue outlet pipe is connected to the fixed rod, the rotating rod is rotatably connected to the fixed rod, the left and right rear sides of the rotating rod are connected to the electric push rods, and the telescopic ends of the electric push rods are detachably connected to the water-absorbing sponges. The rotating rod on the fixed rod is rotated to align the water-absorbing sponge with the glue outlet of the glue outlet pipe, and then the electric push rod is started to push the water-absorbing sponge to move backward into the glue outlet pipe, and then the water-absorbing sponge is moved forward to leave the glue outlet pipe.

[0008] Furthermore, both the rubber inlet and outlet pipes are sprayed with Teflon coating, which has the advantages of non-stickiness: almost all substances do not adhere to the Teflon coating, moisture resistance: the surface of the Teflon coating does not stick to water and oil, and is not easily contaminated by solutions during production operations. If there is a small amount of dirt, it can be removed by simple wiping, heat resistance, sliding, wear resistance and corrosion resistance.

[0009] Furthermore, an auxiliary mechanism is also included, which includes a fixed column, a rotating cover and a locking pin. The front side of the glue outlet pipe is connected with a fixed column, and a rotating cover is rotatably connected to the fixed column. The rotating cover is in contact with the glue outlet pipe. A locking pin is clamped between the rotating cover and the fixed column. A nut is provided on the locking pin. The rotating cover on the fixed column is rotated to close the glue outlet of the glue outlet pipe. Then the locking pin is inserted between the rotating cover and the fixed column, and the rotating cover is fixed by the nut.

[0010] Furthermore, a docking piece is provided on the air intake pipe.

[0011] Furthermore, a protective ring is provided on the dispensing body.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model adopts Teflon coating to spray the two components of the rubber inlet pipe and the rubber outlet pipe, which is convenient for cleaning and prevents the colloid from being blocked and solidified. Then, by starting the electric push rod, the water-absorbing sponge is pushed to move backward into the rubber outlet pipe, and then the water-absorbing sponge is moved forward to leave the rubber outlet pipe, so that the colloid in the rubber outlet pipe can be cleaned to avoid colloid residue.

[0013] 2. The utility model rotates the rotating cover on the fixed column to close the glue outlet of the glue outlet pipe, and then inserts the locking pin between the rotating cover and the fixed column, and fixes the rotating cover with a nut, thereby achieving the effect of closing the glue outlet pipe and preventing dust from entering.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A dispensing valve that can avoid colloid residue in the pipeline, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 As shown, it includes an air intake pipe 1, a regulating valve 2, a dispensing body 3, a side air pipe 4, a glue inlet pipe 5, a glue outlet pipe 6 and a cleaning mechanism 7.

[0025] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the cleaning mechanism 7 includes a fixed rod 71, a rotating rod 72, an electric push rod 73 and a water-absorbing sponge 74. The left part of the glue outlet pipe 6 is connected to the fixed rod 71, the rotating rod 72 is rotatably connected to the fixed rod 71, the left and right rear sides of the rotating rod 72 are connected to the electric push rods 73, and the telescopic ends of the electric push rods 73 are detachably connected to the water-absorbing sponges 74.

[0026] When the utility model is used, glue A and glue B are introduced into the glue dispensing body 3 through the glue inlet pipe 5, and the air intake of the air inlet pipe 1 is controlled by the regulating valve 2. When the regulating valve 2 is opened, the air inlet pipe 1 takes in air, and the colloid in the glue dispensing body 3 does not flow out. When the regulating valve 2 is closed and the side air pipe 4 takes in air, the colloid flows out from the glue outlet pipe 6. The two components of the glue inlet pipe 5 and the glue outlet pipe 6 are sprayed with Teflon coating, which is easy to clean and prevents the colloid from being blocked and solidified. The Teflon coating has non-stickiness: almost all substances do not adhere to the Teflon coating film, and moisture resistance: the surface of the Teflon coating film does not get wet with water and oil. During production operation It is also not easy to be stained with solution. If there is a small amount of dirt, it can be removed by simply wiping.

Then the electric push rod 73 is started to push the water-absorbing sponge 74 to move backward into the glue outlet pipe 6, and then the water-absorbing sponge 74 is moved forward to leave the glue outlet pipe 6, thereby playing a role in cleaning the colloid in the glue outlet pipe 6 and avoiding colloid residue.

[0027] like Figure 1 , Figure 6 and Figure 7 As shown, an auxiliary mechanism 8 is also included, and the auxiliary mechanism 8 includes a fixed column 81, a rotating cover 82 and a locking pin 83. The front side of the glue outlet pipe 6 is connected to the fixed column 81, and the rotating cover 82 is rotatably connected to the fixed column 81. The rotating cover 82 is in contact with the glue outlet pipe 6, and a locking pin 83 is clamped between the rotating cover 82 and the fixed column 81, and a nut is provided on the locking pin 83.

[0028] The auxiliary mechanism 8 of the device can be used to prevent dust from entering the glue outlet pipe 6. After the glue outlet pipe 6 is cleaned, the locking pin 83 is removed, and the rotating cover 82 on the fixed column 81 is rotated to make the rotating cover 82 close the glue outlet of the glue outlet pipe 6.
