Description

Technical Field

[0001] The present invention relates to the technical field of glue filling equipment, and in particular to a quantitative automatic glue feeding device. Background Art

[0002] In modern production, in order to improve the strength of the material, the outer surface of the material is coated with glue to increase the hardness of the material. In the manufacturing process of carbon fiber materials, the base fiber material is continuously polymerized to form a high-hardness carbon fiber material. In the process of carbon fiber polymerization, the surface of the fiber material can be gelled to strengthen the various physical properties of the fiber material. Simple glue coating may cause defects on the surface of the fiber material during gelation. The dipping method can ensure the integrity of the gelation, but there may be too much glue on the surface of the fiber material, which requires quantitative treatment.

[0003] Generally, two-component glue is used. The equipment is equipped with two glue storage barrels to store the glue separately, which effectively avoids the problem of curing after mixing. When using, glue liquid A and glue liquid B need to be mixed. If there is too much liquid A, the mixed glue will be in a state that is not easy to dry. If there is too much liquid B, the mixed glue will be in a state that is easy to dry, causing the spray gun to be blocked, or a large amount of glue will be attached to the fiber material. As long as the ratio is appropriate, the mixed liquid can reach a state suitable for dipping and adhesion. Summary of the invention

[0011] Furthermore, the glue spraying device includes a first mounting frame, a transverse slide rail, a worm gear, a first servo motor, a vertical displacement mechanism, a glue spray gun, and a worm seat.

[0014] The vertical displacement mechanism moves horizontally along the transverse slide rail to the side away from the material receiving mechanism, and the second servo motor outputs torque to the first transmission seat. The first transmission seat is connected to the sliding connection seat through a belt drive. The belt converts the torque output by the second servo motor into longitudinal reciprocating motion, and the sliding connection seat drives the glue spray gun to be lowered to the top of the glue dipping tank.

[0015] Furthermore, the quantitative glue control device includes a second mounting frame, a hinge seat, an arc-shaped connecting piece, a mounting plate, and a nozzle.

[0016] The fiber material that has been impregnated with glue is pulled out of the glue surface in the glue pool under the traction of the material receiving mechanism. The jet head can change the direction of the air outlet through the arc-shaped connecting piece. The amount of air outlet of the jet head changes with the rotation speed of the material receiving mechanism through the jet head connected to the air pipe. When the rotation speed of the material receiving mechanism is fast, the air outlet of the quantitative glue control device all discharges air to increase the air volume, and the air outlet angle of the quantitative glue control device is adjustable. When controlling the glue of fiber materials with different cross-sectional radii, the angle of the side air outlet can be adjusted to avoid dead corners when the fiber material is air-dried and controlled. Through the air outlet in four directions, the surface of the fiber material is discharged at multiple angles, so that the glue on the surface of the fiber material can be evenly attached; the excess glue attached to the surface of the fiber material is blown back to the recovery tank for recycling.

[0018] If there is too much liquid A in the first glue tank, the mixed glue will be in a state that is not easy to dry. When the glue is quantitatively controlled, a large amount of it will be blown away. The liquid B in the second glue tank is mainly a curing agent. If there is too much liquid B, the mixed glue will be in a state that is easy to dry, causing the spray gun to be blocked, or a large amount of glue will adhere to the fiber material. As long as the ratio is appropriate, the mixed liquid can reach a state suitable for dipping and adhesion. The weight sensor senses the weight change of the glue in the inner shell. When the weight of the glue drops too fast, the ratio of liquid A is too much. When the weight of the glue drops too slowly, the ratio of liquid A is too little. The weight sensor generates an electrical signal to the third servo motor, and the flow adjustment mechanism is driven by the third servo motor to control the amount of glue entering the glue pump from the glue extraction hose. The glue pump inputs the glue into the glue spraying device through the glue outlet hose.

[0019] Furthermore, the flow adjustment mechanism includes a transmission rod, a front baffle valve plate, and a rear baffle valve plate.

[0020] The third servo motor receives the electrical signal and outputs torque to the transmission rod. The transmission rod drives the front valve plate to rotate. The rear valve plate is fixed to the inner wall of the rubber extraction hose. The flow rate of the glue liquid is controlled by the degree of overlap between the first through hole on the front valve plate and the second through hole on the rear valve plate. When the first through hole and the second through hole completely overlap, the full flow passes through, the overlapping area decreases, and the amount of glue passing through is reduced.

When the rotation speed of the material receiving mechanism is fast, the air outlet of the quantitative glue control device all discharges air, so that the air volume is increased, and the air outlet angle of the quantitative glue control device is adjustable. When controlling the glue of fiber materials with different cross-sectional radii, it can be adjusted through The angle of the side air outlet is adjusted to avoid dead corners when the fiber material is air-dried and glue is controlled. The glue on the surface of the fiber material can be evenly attached by air outlet in four directions.

[0040] Before the fiber material is impregnated with glue, the first servo motor 44 outputs torque to the worm member 43, and the worm member 43 is connected to the vertical displacement mechanism 45 by a thread. The worm member 43 converts the torque output by the first servo motor 44 into horizontal transverse movement of the vertical displacement mechanism 45 along the worm member 43, and the vertical displacement mechanism 45 moves transversely along the transverse slide rail 42 to a side away from the material receiving mechanism 3.

[0043] like Figure 5As shown, the quantitative glue control device 5 includes a second mounting frame 51, a hinge seat 52, an arc-shaped connecting member 53, a mounting plate 54, and a nozzle 55. The second mounting frame 51 is fixedly connected to the glue pool 2, the second mounting frame 51 is fixedly connected to the hinge seat 52, the arc-shaped connecting member 53 is hinged to the hinge seat 52, and one end of the arc-shaped connecting member 53 away from the hinge seat 52 is hinged to the mounting plate 54. The nozzle 55 is provided with a plurality of groups, and a plurality of groups of nozzles 55 are fixedly connected to the mounting plate 54, and a plurality of groups of nozzles 55 are fixedly connected to the hinge seat 52.

[0044] The fiber material that has been impregnated with glue is pulled out of the glue surface in the glue pool 2 under the traction of the material receiving mechanism 3. The air jet 55 can change the direction of the air outlet through the arc-shaped connecting piece 53. The amount of air outlet of the air jet 55 changes with the rotation speed of the material receiving mechanism 3 through the air jet 55 connected to the air pipe.

When controlling the glue of fiber materials with different cross-sectional radii, the angle of the side air outlet can be adjusted to avoid dead corners when the fiber materials are air-dried and controlled. Through the air outlet in four directions, the surface of the fiber material is discharged at multiple angles, so that the glue on the surface of the fiber material can be evenly attached; the excess glue attached to the surface of the fiber material is blown back to the recovery tank 21 for recycling.

[0045] like Figure 6 As shown, the first glue tank 6 includes an outer shell 61, a glue pump 62, an inner shell 63, a glue discharge pipe 64, a glue discharge pipe 65, a weight sensor 66, a third servo motor 67, a flow adjustment mechanism 68, and a bottom pulley 69. The outer shell 61 is fixedly connected to the glue pump 62, the outer shell 61 is slidably connected to the inner shell 63, the glue discharge pipe 64 is connected to the glue spraying device 4 through a pipeline, the glue discharge pipe 64 is fixedly connected to the glue pump 62, the glue discharge pipe 65 is fixedly connected to the glue pump 62, the weight sensor 66 is fixedly connected to the inner shell 63, the third servo motor 67 is fixedly connected to the outer shell 61, the weight sensor 66 is connected to the third servo motor 67 through an electrical signal, the third servo motor 67 is transmission-connected to the flow adjustment mechanism 68, the flow adjustment mechanism 68 is fixedly connected to the glue discharge pipe 65, and the bottom pulley 69 is fixedly connected to the outer shell 61.

If there is too much liquid B, the mixed glue will be in a state that is easy to dry, causing the spray gun to be blocked, or a large amount of glue will adhere to the fiber material. As long as the ratio is appropriate, the mixed liquid can reach a state suitable for dipping and adhesion. The weight sensor 66 senses the weight change of the glue in the inner shell 63. When the weight of the glue drops too fast, the ratio of liquid A is too much. When the weight of the glue drops too slowly, the ratio of liquid A is too little. The weight sensor 66 generates an electrical signal to the third servo motor 67, and the flow adjustment mechanism 68 is transmitted by the third servo motor 67 to control the amount of glue entering the glue pump 62 from the glue extraction pipe 65. The glue pump 62 inputs the glue into the glue spraying device 4 through the glue outlet pipe 64.

[0048] The third servo motor 67 receives the electrical signal and outputs the torque to the transmission rod 681. The transmission rod 681 drives the front valve plate 682 to rotate. The rear valve plate 683 is fixed to the inner wall of the glue extraction tube 65. The flow rate of the glue is controlled by the degree of overlap between the first through hole 6821 on the front valve plate 682 and the second through hole 6831 on the rear valve plate 683. When the first through hole 6821 and the second through hole 6831 completely overlap, the full flow rate passes through, the overlapping area is reduced, and the amount of glue passing through is reduced.

Liquid B is mainly a curing agent. If there is too much liquid B, the mixed glue liquid will be in a state that is easy to dry, causing the spray gun to be blocked. The glue liquid is attached to the fiber material in large quantities. Only when the ratio is appropriate, the mixed liquid can reach a state suitable for dipping and attachment. The weight change of the glue liquid in the inner shell 63 is sensed by the weight sensor 66, and the weight sensor 66 generates an electrical signal. The flow adjustment mechanism 68 is driven by the third servo motor 67 to control the amount of glue entering the glue pump 62 from the glue extraction pipe 65. The glue pump 62 inputs the glue liquid into the glue spraying device 4 through the glue outlet pipe 64; the fiber material after the dipping is completed is pulled out of the glue surface in the glue pool 2 under the action of the receiving mechanism 3. With the receiving speed of the receiving mechanism 3, the quantitative glue control device 5 blows the excess glue on the surface of the fiber material into the glue pool 2, and the fiber material with surface glue coating is rolled onto the receiving mechanism 3.
