An adhesive spraying device for tape production

Abstract

This utility model discloses an adhesive spraying device for tape production. Its structure includes a spray pump, a spraying mechanism, a control box, and a hose. The hose is installed on the upper end of the spray pump, which is embedded in the upper end of the spraying mechanism. The control box is installed on the side of the spraying mechanism and is connected to the internal wiring of both the spraying mechanism and the spray pump. In this utility model, when the adhesive plate is stretched and taut on the buffer rod, causing excessive friction, the sliding rod moves elastically to the right within the track plate under the elastic force of the rubber rod. This reduces the friction between the outer side of the force ring and the adhesive plate, preventing excessive tension on the left side of the adhesive plate and preventing excessive compression of the adhesive plate after spraying. This avoids excessive thickness of the adhesive after compression. Furthermore, when the adhesive is sprayed from the spray head, intermittent blocking spraying creates a strip-shaped, spaced spray pattern from the four spray heads. This allows the strip-shaped adhesive to converge and form a flat surface after the adhesive plate shrinks, preventing the adhesive from being squeezed and protruding.

Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to an adhesive spraying equipment for tape production. Background Technology

[0002] During tape production, the tape is moved using a transmission method, and then adhesive is sprayed onto the tape, giving it the adhesive properties. During processing, the bonding plate needs to be horizontally driven so that the adhesive is sprayed onto its surface. Then, the other side of the adhesive is bonded together to achieve tape production. The tape has a double-sided adhesive effect and can firmly adhere to most solid objects.

[0003] However, the adhesive plate of the sponge tape is made of sponge material. Adhesive is sprayed onto the adhesive plate to form the tape. The adhesive plate has a certain elasticity and stretching effect. During spraying, it is in a horizontally stretched and taut state at both ends. After spraying, the adhesive plate is in a contracted state, which can easily cause the adhesive on the surface to be squeezed against each other. This can easily lead to the problem of excessively thick adhesive on the surface after spraying. In addition, the spraying is done in a vertical state, which is a continuous spraying. It can easily cause the spraying to be too dense, causing the adhesive to be squeezed against each other and protrude after the adhesive plate contracts. Utility Model Content

The hose is installed on the upper end of the spray pump, which is embedded in the upper end of the spraying mechanism. The control box is installed on the side of the spraying mechanism and is connected to the internal wiring of both the spraying mechanism and the spray pump. The spraying mechanism includes a sprayer, a machine base, a rotating rod, and a buffer rod. The sprayer is embedded in the upper inner side of the machine base, the buffer rod is installed inside the machine base, and the rotating rod is movably engaged inside the machine base. The buffer rod and the rotating rod are at the same horizontal position. The spray pump is embedded in the upper end of the machine base, and the upper end of the sprayer is connected to the lower end of the spray pump. The control box is installed on the side of the machine base, and the spraying mechanism is connected to the rotating rod via wiring. A motor is installed on the side of the rotating rod, and the motor is threadedly engaged with the rotating rod. The hose facilitates the flow of adhesive.

[0005] As a further optimization of this technical solution, the buffer rod is provided with a rotating rod, a rubber rod, a force-bearing ring, a sliding rod, and a track plate. The rotating rod is embedded outside the sliding rod, the force-bearing ring is attached to the outside of the rotating rod, the sliding rod slides horizontally on the inside of the track plate, the left end of the rubber rod and the right side of the sliding rod are mutually pressed together, the rubber rod is installed inside the right side of the track plate, the track plate is installed inside the machine, the force-bearing ring is made of rubber and has a certain friction, and the track plate is in a horizontal state.

[0006] As a further optimization of this technical solution, the sprayer is equipped with a spray head, a blocking rod, a vertical tube, and a spray plate. The spray head is embedded in the lower end of the spray plate, the vertical tube is installed in the middle of the spray plate and is connected to the pipe inside the spray head, the blocking rod is embedded in the right side of the inside of the spray plate, the spray plate is embedded in the upper end of the inner side of the machine, the pipe at the upper end of the vertical tube is connected to the lower end of the spray pump, and there are four spray heads arranged horizontally and evenly at intervals. A motor is threadedly fitted on the side of the blocking rod and the motor is connected to the control box wiring.

Beneficial effects

[0009] This utility model provides an adhesive spraying device for tape production, which has the following advantages compared with the prior art:

[0010] In this invention, the control box controls the rotation of the rotating rod, causing the sponge adhesive plate of the tape to be horizontally stretched and moved from the positions of the buffer rod and the rotating rod. Under the rotation of the rotating rod, the adhesive plate moves to the right and rubs against the outside of the force ring in the buffer rod, causing the rotating rod to rotate outside the sliding rod. When the friction is too great, the sliding rod moves elastically to the right within the track plate under the elastic force of the rubber rod, reducing the friction between the outside of the force ring and the adhesive plate. This prevents the tension on the left side of the adhesive plate from being too great and making it too tight, and prevents the adhesive plate from rebounding and compressing too much after spraying, thus avoiding excessive thickness of the adhesive after extrusion.

[0011] In this invention, the adhesive is sprayed downwards from a vertical tube under pressure. During spraying, the motor is controlled to rotate the blocking rod, causing the blocking rod to intermittently block the vertical tube. As the adhesive is sprayed from the spray head, the intermittent blocking spraying creates a strip-shaped spraying state from the four spray heads. The distance the adhesive plate moves during the interval is the distance of one spray plate, thus ensuring that the adhesive plate is evenly sprayed in strips. After the adhesive plate shrinks, the strips of adhesive come close together to form a flat surface, preventing the adhesive from being squeezed and protruding. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the preferred embodiments of this utility model are further described below in conjunction with specific implementation methods and accompanying drawings. Example

[0020] Please see Figures 1-5This utility model provides an adhesive spraying device for tape production, which includes a spray pump 1, a spraying mechanism 2, a control box 3, and a hose 4. The hose 4 is installed on the upper end of the spray pump 1, and the spray pump 1 is embedded in the upper end of the spraying mechanism 2. The control box 3 is installed on the side of the spraying mechanism 2 and is connected to the internal wiring of the spraying mechanism 2 and the spray pump 1. The spraying mechanism 2 includes a sprayer 21, a machine base 22, a rotating rod 23, and a buffer rod 24. The sprayer 21 is embedded in the upper inner side of the machine base 22, the buffer rod 24 is installed inside the machine base 22, and the rotating rod 23 is movably engaged inside the machine base 22. The buffer rod 24 and the rotating rod 23 are located at the same horizontal position. The spray pump 1 is embedded in the machine base 22. At the upper end, the upper pipe of the sprayer 21 is connected to the lower end of the spray pump 1. The control box 3 is installed on the side of the machine base 22, and the spraying mechanism 2 is connected to the rotating rod 23 by wiring. A motor is provided on the side of the rotating rod 23, and the motor is threadedly engaged with the rotating rod 23. The hose 4 has the effect of flowing adhesive. Then the spray pump 1 draws adhesive through the upper hose 4, so that the adhesive is sprayed vertically downward from the sprayer 21. The control box 3 controls the rotating rod 23 to rotate, so that the sponge adhesive plate of the tape is horizontally stretched and moved from the position of the buffer rod 24 and the rotating rod 23. The sprayer 21 sprays adhesive onto the surface of the adhesive plate. The buffer rod 24 keeps the rotation driving force of the rotating rod 23 with a small stretch on the adhesive plate, preventing the adhesive plate from being stretched too tightly.

[0021] The buffer rod 24 includes a rotating rod w1, a rubber rod w2, a force-bearing ring w3, a sliding rod w4, and a track plate w5. The rotating rod w1 is embedded outside the sliding rod w4, the force-bearing ring w3 is fitted against the outside of the rotating rod w1, the sliding rod w4 slides horizontally on the inside of the track plate w5, the left end of the rubber rod w2 is pressed against the right side of the sliding rod w4, the rubber rod w2 is installed inside the right side of the track plate w5, the track plate w5 is installed inside the machine base 22, and the force-bearing ring w3 is made of rubber. The adhesive material has a certain friction. The track plate w5 is in a horizontal state, so the adhesive plate moves to the right and rubs outside the force ring w3, causing the rotating rod w1 to rotate outside the sliding rod w4. When the friction is too great, the sliding rod w4 moves elastically to the right inside the track plate w5 under the elastic force of the rubber rod w2, so that the friction between the outside of the force ring w3 and the adhesive plate is reduced, avoiding excessive tension on the left side of the adhesive plate, making it too tight, and preventing the adhesive plate from rebounding and compressing too much after spraying, thus avoiding excessive thickness of the adhesive after extrusion.

[0022] The sprayer 21 includes a spray head t1, a blocking rod t2, a vertical tube t3, and a spray plate t4. The spray head t1 is embedded in the lower end of the spray plate t4. The vertical tube t3 is installed inside the middle of the spray plate t4 and is connected to the internal pipe of the spray head t1. The blocking rod t2 is embedded in the right side of the inside of the spray plate t4. The spray plate t4 is embedded in the upper part of the inner side of the machine base 22. The upper pipe of the vertical tube t3 is connected to the lower end of the spray pump 1. There are four spray heads t1, which are arranged horizontally and evenly. The blocking rod t2 has a motor threadedly connected to its side. The motor is connected to the control box 3, so that the adhesive is pressed down from the vertical tube t3. During spraying, the motor controls the rotation of the blocking rod t2, causing the blocking rod t2 to intermittently block the vertical tube t3. As the adhesive is sprayed from the spray head t1, the intermittent blocking spraying causes the spraying of the four spray heads t1 to form a strip-shaped interval spraying state. When the blocking rod t2 blocks the adhesive in the vertical tube t3, the moving speed of the lower adhesive plate is equal to the width of the spray plate t4. Thus, the length of each spray is equal to the width of the spray plate t4, and the length of the adhesive plate moving during the interval is equal to the distance of one spray plate t4. This makes the adhesive plate evenly sprayed in strips, so that after the adhesive plate shrinks, the strip adhesive comes close to each other and forms a plane, avoiding the adhesive from being squeezed and protruding.

[0023] The blocking rod t2 is equipped with a rubber ring t21, a threaded rod t22, and a sector block t23. The rubber ring t21 is attached to the outside of the threaded rod t22, and the sector block t23 is embedded in the outside of the rubber ring t21. The threaded rod t22 is embedded in the right side of the inside of the spray plate t4. The threaded rod t22 is threadedly engaged with the motor. There are three sector blocks t23, which are evenly distributed in a ring. This controls the motor to drive the threaded rod t22 to rotate continuously counterclockwise, causing the sector blocks t23 to rotate and block inside the vertical tube t3. At the same time, under the elastic force of the rubber ring t21, the sector blocks t23 slide and rub tightly against the inside of the vertical tube t3, avoiding the formation of gaps in the vertical tube t3. This achieves the effect of blocking the adhesive inside the vertical tube t3. The three sector blocks t23 intermittently block the flow of adhesive, achieving an intermittent spraying effect.

[0024] The spray head t1 is equipped with an inclined tube, which is symmetrically distributed on the left and right sides with the vertical tube t3 as the center. The upper middle position of the inclined tube is located directly below the vertical tube t3. Thus, when the vertical tube t3 sprays downwards, the adhesive is evenly sprayed downwards from the upper middle of the inclined tube, which avoids unevenness of the adhesive flowing into the four spray heads t1 from the vertical tube t3 and prevents differences in the spraying amount of the four spray heads t1.

[0025] Working principle: In this invention, the spray pump 1, powered by electricity, draws adhesive through the upper hose 4, causing the adhesive to be sprayed vertically downwards from the sprayer 21. The control box 3 controls the rotation of the rotating rod 23, causing the sponge adhesive plate of the tape to move horizontally from the positions of the buffer rod 24 and the rotating rod 23. The sprayer 21 sprays adhesive onto the surface of the adhesive plate. The buffer rod 24 maintains a small tension on the adhesive plate due to the rotational force of the rotating rod 23, preventing the adhesive plate from becoming excessively taut. Furthermore, under the rotation of the rotating rod 23, the adhesive plate moves to the right and rubs against the force ring w3 in the buffer rod 24, causing the rotating rod w1 to rotate outside the sliding rod w4. When the friction is too great, the sliding rod w4 moves elastically to the right within the track plate w5 under the elastic force of the rubber rod w2, reducing the friction between the outer side of the force ring w3 and the adhesive plate. This prevents the tension on the left side of the adhesive plate from being too great and making it too tight, and prevents the adhesive plate from rebounding and compressing too much after spraying, thus avoiding excessive thickness of the adhesive after extrusion.

[0026] In this invention, the adhesive is sprayed downwards from the vertical pipe t3 under pressure. This ensures that the adhesive is evenly sprayed from the upper middle of the inclined pipe t3 into the spray head t1, preventing uneven application of the adhesive into the four spray heads t1 and ensuring consistent spray volume. Furthermore, the motor controls the rotation of the blocking rod t2 during spraying, causing it to intermittently block the vertical pipe t3. This further ensures that the adhesive is intermittently sprayed from the spray head t1. The blocking spraying method causes the four spray heads t1 to spray in a strip-shaped interval state. When the blocking rod t2 blocks the adhesive in the vertical tube t3, the moving speed of the lower adhesive plate is equal to the width of the spray plate t4. Therefore, the length of each spray is equal to the width of the spray plate t4, and the length of the adhesive plate moving in the interval is equal to the distance of one spray plate t4. This makes the adhesive plate evenly sprayed in strips, so that after the adhesive plate shrinks, the strip adhesive comes close to each other and forms a plane, avoiding the adhesive from being squeezed and protruding.
