Description

Technical Field

[0001] The utility model relates to the technical field of accessories processing, in particular to automatic glue spraying equipment for automobile parts. Background Art

[0002] Patent publication number CN217392829U relates to an automatic glue spraying device for automotive parts, comprising a glue cartridge and a glue head. The glue head is disposed at the bottom of the glue cartridge, a sealing cap is disposed at the top of the glue cartridge, an air intake pipe is fixedly connected to the top of the sealing cap, a connecting pipe is fixedly connected to the right side of the air intake pipe, a sealing rubber column is sleeved on the outer surface of the connecting pipe, a sealing plug is disposed at the right end of the connecting pipe, and a connecting valve is installed on the outer surface of the connecting pipe. The automatic glue spraying device for automotive parts is configured by installing a sealing cap at the top of the glue cartridge. When the glue is squeezed out of the glue head and the glue spraying is completed, the sealing plug is plugged into the connecting pipe, and a pressure relief bolt is rotated to suck the remaining gas in the glue cartridge out of the pressure relief pipe, thereby preventing air from remaining inside the glue cartridge, which would cause the glue inside the glue cartridge to oxidize upon contact with air, resulting in a decrease in the performance of the glue and affecting the glue spraying effect.

[0003] The above technology requires manual opening of the sealing plug and injection of glue into the rubber cylinder during use. After stopping use, the sealing plug needs to be manually inserted into the connecting tube to discharge the gas in the rubber cylinder, which increases the complexity of the operation of the staff and is prone to human errors. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic glue spraying device for automobile parts.

[0005] The technical problem solved by the utility model is to reduce the complexity of operation and avoid human operation errors.

[0006] The utility model can be realized through the following technical scheme: it includes a connecting tube fixedly connected to the bottom of the rubber cylinder, a rubber head fixedly connected to the bottom of the connecting tube, a rubber delivery tube fixedly connected to the top side of the rubber cylinder, a rotating rod that can automatically rotate is rotatably installed through the rubber cylinder, a fixed plate rotatably connected to the bottom end of the rotating rod is fixedly installed in the connecting tube, two mutually symmetrical glue holes are provided on the fixed plate, a pair of spiral plates symmetrical to each other are fixedly installed at a position near the top of the fixed plate on the outer peripheral wall of the rotating rod, a shielding plate corresponding to the glue holes is fixedly installed on the bottom of the spiral plate, and the bottom of the shielding plate is in contact with the top of the fixed plate.

[0007] A further technical improvement of the present invention is that the shielding plate is made of silicone material.

[0008] Furthermore, the structure that causes the rotating rod to rotate automatically includes a pair of push plates fixedly installed on the top of the outer wall of the rotating rod, a sliding groove is provided on the push plate, a slider is slidably installed in the sliding groove, a sliding rod is slidably installed through the slider, and the opposite ends of the two sliding rods are fixedly connected to the top of the rubber cylinder by a support plate, and a spring 2 is fixedly installed between the slider and the support plate and is sleeved on the outer wall of the sliding rod.

[0009] Furthermore, a first piston cylinder and a second piston cylinder are fixedly connected to each other at a position near the bottom of the fixed plate on the outer wall of the connecting tube, a first piston rod is slidably installed in the first piston cylinder, a spring is fixedly installed between the first piston rod and the first piston cylinder, and a second piston rod is slidably installed in the second piston cylinder and moves opposite to the first piston rod.

[0010] Furthermore, the structure that causes the first piston rod and the second piston rod to move toward each other includes a connecting plate 2 that is rotatably connected to the outer peripheral wall of the connecting tube, and connecting plate 1 is rotatably installed at both ends of connecting plate 2. The ends of the two connecting plates 1 away from connecting plate 2 are respectively rotatably connected to the ends of the first piston rod and the second piston rod away from the connecting tube.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this application, when pressure is applied to the glue, the shielding plate is separated from the top of the glue hole. After the pressure on the glue disappears, the shielding plate is re-covered on the top of the glue hole, so that after the glue head stops spraying glue, the glue is automatically sealed in the glue cylinder, reducing the complexity of manual operation.

[0013] 2. When the glue is squeezed into the rubber head, the first piston rod is squeezed into the first piston cylinder, thereby filling the second piston cylinder with gas. After the glue stops flowing, the gas in the second piston cylinder automatically squeezes into the rubber head, and the glue in the rubber head is discharged to the outside of the rubber head, preventing the glue from oxidizing and solidifying inside the rubber head and clogging the rubber head.

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0020] See also Figure 1-3 As shown, this embodiment provides an automatic glue spraying device for automobile parts, including a glue cartridge 1, a connecting pipe 2 is fixedly connected to the bottom of the glue cartridge 1, a glue head 3 is fixedly connected to the bottom of the connecting pipe 2, a glue delivery pipe 4 is installed on one side of the top of the glue cartridge 1, one end of the glue delivery pipe 4 is fixedly connected to the glue cartridge 1, and the other end of the glue delivery pipe 4 is fixedly connected to a glue storage tank (not shown in the figure), a glue pump is installed on the glue delivery pipe 4 to drive the glue delivery pipe 4 to suck the colloid in the glue storage tank into the glue cartridge 1, the glue delivery pipe 4 inputs glue into the glue cartridge 1, after the glue cartridge 1 is full of glue, its internal pressure increases, causing the glue to flow into the connecting pipe 2 at the bottom of the glue cartridge 1, and finally sprayed from the glue head 3 to the connecting parts of the automobile parts,

[0021] A rotating rod 5 is rotatably installed in the rubber cylinder 1, and a fixing plate 6 is fixedly installed near the bottom end of the rotating rod 5 in the connecting tube 2. The bottom end of the rotating rod 5 is rotatably connected to the fixing plate 6. Two mutually symmetrical glue holes 7 are provided on the fixing plate 6. A pair of mutually symmetrical spiral plates 8 are fixedly installed on the outer peripheral wall of the rotating rod 5 near the position above the fixing plate 6. A shielding plate 9 corresponding to the glue hole 7 is fixedly installed at the bottom of the spiral plate 8. The bottom of the shielding plate 9 is in contact with the top of the fixing plate 6. The shielding plate 9 is made of silicone material to enhance the sealing between it and the fixing plate 6.

[0022] When the glue flows into the connecting pipe 2 due to the internal pressure, the pressurized glue squeezes the surface of the spiral plate 8 that is in direct contact with the glue, causing the spiral plate 8 to drive the rotating rod 5 to rotate, thereby causing the spiral plate 8 to drive the shielding plate 9 to separate from the top of the glue hole 7, so that the glue flows through the glue hole 7 to the glue head 3, and finally the glue is sprayed from the glue head 3 to the connection of the automobile parts;

[0023] A first piston cylinder 10 and a second piston cylinder 11 are fixedly connected to each other at a position near the bottom of the fixed plate 6 on the outer peripheral wall of the connecting pipe 2. A first piston rod 12 is slidably installed in the first piston cylinder 10, and a second piston rod 13 is slidably installed in the second piston cylinder 11. A spring 14 is fixedly installed between the first piston rod 12 and the first piston cylinder 10 and is sleeved on the outer peripheral wall of the first piston rod 12. A one-way valve (not shown in the figure) is installed on the second piston cylinder 11 to facilitate unidirectional gas transportation to the second piston cylinder 11. A one-way valve (not shown in the figure) is provided between the second piston cylinder 11 and the connecting pipe 2 to facilitate unidirectional gas transportation from the second piston cylinder 11 to the connecting pipe 2. A connecting plate 15 is rotatably installed on the ends of the first piston rod 12 and the second piston rod 13 away from the connecting pipe 2. A connecting plate 2 16 is rotatably installed between the two connecting plates 15. The connecting plate 2 16 is rotatably connected to the outer peripheral wall of the connecting pipe 2.

[0024] When the glue flows to the glue head 3, because the diameter of the glue head 3 is too small and the glue flow rate is large, the excess glue will be squeezed in the direction of the first piston rod 12, causing the first piston rod 12 to squeeze the spring 14 and drive the connecting plate 2 16 to rotate through the connecting plate 15, prompting the other connecting plate 15 to drive the other piston rod to slide in its extension direction, sucking gas from the second piston cylinder 11. Then, when the glue stops flowing, the pressure on the first piston rod 12 is released, thereby causing the spring 14 to rebound, driving the first piston rod 12 to move into the connecting pipe 2 and squeeze the glue in the first piston cylinder 10 out of the glue head 3. At this time, the first piston rod 12 drives the connecting plate 2 16 to rotate through the connecting plate 15 rotatably connected thereto, prompting the rotating plate 2 to drive the other piston rod to squeeze into the connecting pipe 2 through the other connecting plate 15, thereby delivering the gas in the second piston cylinder 11 to the glue head 3, and squeezing out the remaining glue in the glue head 3;

[0025] A pair of push plates 17 are fixedly installed on the top of the outer peripheral wall of the rotating rod 5. A slide groove 18 is opened on the push plate 17. A slider 19 is slidably installed in the slide groove 18. A slide rod 20 is slidably installed on the slider 19. The opposite ends of the two slide rods 20 are fixedly connected to the top of the rubber cylinder 1 by a support plate 21. A spring 22 is fixedly installed between the slider 19 and the support plate 21 and is sleeved on the outer peripheral wall of the slide rod 20.

[0026] When the rotating rod 5 rotates due to the glue squeezing the spiral plate 8, the slider 19 will be driven by the push plate 17 to squeeze the spring 22, so that the spring 22 is in a stressed state, and the slider 19 slides along the extension direction of the slide rod 20 and slides in the slide groove 18 to correct the positional relationship between the push plate 17 and the slide rod 20. When the glue is no longer squeezing the spiral plate 8, the stressed state of the spring 22 is released, and then it rebounds and squeezes the slider 19, so that the push plate 17 drives the rotating rod 5 to rotate to its original state, so that the rotating rod 5 drives the baffle plate 9 to cover the top of the glue hole 7 through the spiral plate 8, thereby closing the flow state of the connecting pipe 2.

[0027] When the utility model is in use, glue is injected into the rubber cylinder 1 through the glue delivery pipe 4. When the rubber cylinder 1 is filled with glue and the glue delivery pipe 4 continues to inject glue into the rubber cylinder 1, the glue will be attached with downward flow pressure, thereby squeezing the spiral plate 8 to rotate the rotating rod 5. The rotating rotating rod 5 drives the shielding plate 9 to separate from the top of the glue hole 7 through the spiral plate 8, so that the glue flows into the glue head 3 through the glue hole 7 and is sprayed from the glue head 3 to the connection part of the automobile parts. In the process of glue flowing to the glue head 3, since the glue spraying amount of the glue head 3 is limited and the flow rate of glue is large, the glue will be squeezed in the direction of the first piston rod 12, so that the first piston rod 12 squeezes the spring 14, and the first piston rod 12 drives the second piston rod 13 to move to the outside of the second piston cylinder 11 through the two connecting plates 15 and 2, so that the glue in the second piston cylinder 11 is injected. Gas. When the infusion tube stops injecting glue into the rubber cylinder 1, the pressure on the spiral plate 8 is released, and the rotating rod 5 rotates to its original state, thereby driving the baffle plate 9 to cover the top of the glue hole 7 again through the spiral plate 8, so that the flow state of the connecting pipe 2 is closed, and the glue no longer flows into the rubber head 3. At the same time, the pressure on the first piston rod 12 is released, and the spring 14 rebounds and squeezes the first piston rod 12 in the direction of the connecting pipe 2, so that the first piston rod 12 squeezes the glue in the first piston cylinder 10 into the rubber head 3 and discharges it. The first piston rod 12 drives the second piston rod 13 to move toward the connecting pipe 2 through the connecting plate 2 16 and the two connecting plates 1 15 at the same time, so that the second piston rod 13 squeezes the gas in the second piston cylinder 11 into the rubber head 3, so that the gas discharges the remaining glue in the rubber head 3 to the outside of the rubber head 3, thereby preventing the glue from oxidizing and solidifying in the rubber head 3 and clogging the rubber head 3.
