Description

Technical Field

[0001] This application relates to the field of automotive armrest adhesive spraying, and in particular to an automotive armrest adhesive spraying device. Background Technology

[0002] Car armrests are composed of multiple components, including a rigid frame (metal, ABS plastic), a flexible cushioning layer (sponge, PU foam), and a surface covering layer (leather, fabric, PVC). In order to firmly bond the multiple components together, glue is usually sprayed onto the surface of the rigid frame before bonding. After the glue is sprayed, the other components are bonded to the surface of the rigid frame, thus completing the assembly of the multiple components of the car armrest.

[0003] Because car handrails come in various regular shapes, most use low-cost and easy-to-operate manual glue spraying machines for glue spraying. The operation process of a manual glue spraying machine is as follows: the operator pulls the trigger of the spray gun to open the valve, and the glue supply pump (pneumatic or manual) pressurizes the glue in the glue tank to the spray gun through the glue hose. When the glue flows through the nozzle, it is atomized or shaped and then sprayed out, adhering to the surface of the workpiece. When the trigger is released, the valve closes, and the glue supply and spraying stop immediately.

[0004] After applying glue with a manual glue sprayer, glue residue remains at the nozzle. If the spray gun is placed elsewhere or held by hand after application, glue near the nozzle will naturally flow out due to its fluidity and drip onto the placement area, causing contamination. When the spray gun is held by hand, due to operator error or holding it downwards, glue near the nozzle will gradually flow into the nozzle and mix with residual glue on the nozzle surface. This mixed glue, being in a liquid state, easily drips onto the surface of the handrail, forming irregular glue dots and reducing the quality of the glue application on the car handrail. Utility Model Content

[0005] To address the problem of adhesive residue remaining at the nozzle after manual glue spraying, which drips and contaminates car armrests, thus reducing the quality of glue application, this application provides a car armrest glue spraying device.

[0006] The automotive armrest adhesive spraying device provided in this application adopts the following technical solution: A car armrest adhesive spraying device includes a manual adhesive spraying machine body, the manual adhesive spraying machine body includes a nozzle, and a sealing plate for sealing the nozzle and a scraper for scraping off residual adhesive on the surface of the nozzle near the sealing plate are provided on one side of the surface of the manual adhesive spraying machine body. The scraper is positioned below the sealing plate, and the surface of the scraper near the nozzle is set as an inclined surface. The surface of the nozzle is provided with a drive mechanism for driving the sealing plate and the scraper to move.

[0007] By adopting the above technical solution, the sealing plate is moved by the drive mechanism to seal the nozzle of the manual glue spraying machine body, preventing air from entering the nozzle and causing the glue to oxidize and solidify. This ensures that the nozzle will not experience glue breakage or uneven glue dispensing in subsequent use. At the same time, the scraper removes residual glue from the nozzle surface, preventing residual glue from dripping off the nozzle surface after glue spraying on the car armrest, thus improving the glue spraying quality of the manual glue spraying machine body on the car armrest.

[0008] Preferably, the surface of the nozzle is provided with a mounting plate for mounting a drive mechanism. The drive mechanism includes a drive plate disposed on the side of the mounting plate away from the surface of the sealing plate, a drive block disposed on one side of the surface of the drive plate, a drive seat disposed on the side of the drive block away from the drive plate, a limiting block disposed on one side of the surface of the drive seat disposed on the side of the drive block away from the drive plate, and a drive frame disposed on the side of the drive seat near the surface of the sealing plate away from the end of the sealing plate.

[0009] By adopting the above technical solution, the drive plate is pulled to move from top to bottom. The drive plate drives the drive block to move, the drive block drives the limit block to move, the limit block drives the drive seat to move, the drive seat drives the drive frame to move, the drive frame drives the sealing plate to move, and the sealing plate drives the scraper to move, thereby achieving simultaneous driving of the sealing plate and the scraper.

[0010] Preferably, the driving plate has symmetrically arranged positioning posts for positioning the driving plate on the side of the surface near the mounting plate, and the mounting plate has symmetrically opened multiple positioning holes that are adapted to the positioning posts on the side of the surface near the driving plate.

[0011] By adopting the above technical solution, before the drive plate is pulled, it is first pushed away from the surface of the mounting plate, so that the drive plate is away from the surface of the mounting plate. This causes the drive plate to drive the positioning pin to disengage from the interior of the positioning hole. When the positioning pin is completely disengaged from the interior of the positioning hole, the positioning pin releases its positioning of the drive plate, allowing the drive plate to be driven by external force to move from top to bottom, thereby controlling the movement state of the sealing plate and the scraper.

[0012] Preferably, the mounting plate has a mounting box on the surface of the drive seat near the sealing plate, and the drive frame has a mounting cylinder inside the mounting box on the surface away from the sealing plate. The mounting cylinder has a spring inside the mounting box, and a mounting block is provided at the end of the spring near the drive frame. Connecting blocks are symmetrically arranged on the surface of the mounting cylinder.

[0013] By adopting the above technical solution, the drive frame moves the connecting block during movement, and the connecting block moves the mounting block, causing the mounting block to press the spring and deform it. After the manual glue sprayer body finishes spraying glue on the car armrest, the user only needs to release the limit on the drive plate, so that the drive frame can quickly seal the nozzle through the spring force, reducing the air entering the nozzle. At the same time, the mounting cylinder inside the mounting box limits the spring to prevent the spring from deviating during the recovery deformation process.

[0014] Preferably, the interior of the mounting box is symmetrically provided with guide rods disposed on the surface of the drive frame, the guide rods being used to guide the drive frame.

[0015] By adopting the above technical solution, the drive frame is guided by the guide rod during movement to prevent deviation during movement.

[0016] Preferably, the mounting plate has a collection box located below the scraper on the side of its surface near the sealing plate. The side of the collection box near the scraper is set as an inclined surface, and a pusher for driving the collection box to move is provided on the side of its surface.

[0017] By adopting the above technical solution, the collection box can be quickly installed under the scraper by pulling the pusher. After the scraper removes the residual glue on the nozzle surface, the collection box can be used to collect it, reducing glue loss and preventing glue from spilling everywhere.

[0018] Preferably, the mounting plate has a mounting base for mounting the collection box on one side of its surface near the sealing plate, and the mounting base has a mounting groove for mounting the collection box on one side of its surface.

[0019] By adopting the above technical solution, the collection box is stored in the mounting slot inside the mounting base, which effectively prevents glue from splashing after being scraped off and reduces the pollution of the manual glue sprayer's operating environment caused by the glue.

[0020] Preferably, the sealing plate is made of silicone and the scraper is made of polytetrafluoroethylene.

[0021] By adopting the above technical solution, the sealing plate is made of silicone material, which allows the sealing plate to fit tightly against the nozzle surface to form a seal, and it is not easy to deform due to being too soft. The scraper is made of polytetrafluoroethylene material to ensure that it will not deform when scraping off the glue on the nozzle surface.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The sealing plate and scraper are moved simultaneously by the drive mechanism to automatically scrape off residual glue from the nozzle and seal the nozzle, effectively preventing glue residue and dripping at the nozzle, avoiding glue contamination of the car handrail after spraying, thereby improving the quality of glue spraying on the car handrail. At the same time, it can prevent external air from entering the nozzle and prevent the glue near the nozzle from hardening due to oxidation.

[0023] 2. The scraper can automatically collect the glue by contacting the collection box, reducing glue waste during the glue spraying process of the car armrest, thereby reducing the glue spraying cost of the car armrest. At the same time, the collection box can be quickly inserted or removed from the mounting base, reducing the difficulty of operation. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0027] This application discloses an adhesive spraying device for automobile armrests.

[0028] Reference Figure 1 A car armrest glue spraying device includes a manual glue spraying machine body 1. The manual glue spraying machine body 1 adopts a 5KG manual glue spraying machine from Shandong Jinjiawang Machinery. The manual glue spraying machine body 1 includes a glue storage module, a glue supply module, a control module, and a spraying module. The spraying module includes a nozzle 11. The nozzle 11 is made of stainless steel. 01 belongs to the prior art. The specific structural principle and working process of each part are not described in detail.

[0029] Reference Figures 3-4 A sealing plate 2 for sealing the nozzle 11 is attached to the outlet of the nozzle 11. A scraper 3 for scraping off residual glue on the surface of the nozzle 11 near the sealing plate 2 is fixedly connected to the lower surface of the sealing plate 2. The surface of the scraper 3 near the nozzle 11 is on the same vertical line as the surface of the sealing plate 2 near the nozzle 11. The side of the scraper 3 near the nozzle 11 is set as an inclined surface with an inclination angle of 15-30°. The inclination angle is 15-20° for low viscosity glue, 20-25° for medium viscosity glue, and 25-30° for high viscosity glue. When a 22° inclination surface is used, the medium viscosity glue can naturally slide off the surface of the scraper 3 under the action of gravity and the inertia of the scraper 3, preventing glue from accumulating on the surface of the scraper 3.

[0030] By sealing the nozzle 11 with the sealing plate 2, outside air can be prevented from entering the nozzle 11, effectively preventing the glue inside the nozzle 11 from hardening due to oxidation. At the same time, the scraper 3 is used to scrape off the residual glue on the surface of the nozzle 11, preventing the residual glue on the surface of the nozzle 11 from dripping and damaging the surface of the car armrest after glue application, thus improving the glue application quality of the manual glue sprayer body 1 on the car armrest.

[0031] Reference Figures 2-8The surface of the nozzle 11 is provided with a drive mechanism 5 for driving the sealing plate 2 and the scraper 3 to move. The surface of the nozzle 11 is fixedly connected with a mounting plate 4 for mounting the drive mechanism 5. One side of the surface of the mounting plate 4 is provided with an installation space 44 to facilitate mounting the mounting plate 4 on the surface of the nozzle 11. The drive mechanism 5 includes a drive plate 51 that abuts against the side of the mounting plate 4 away from the surface of the sealing plate 2. One side of the surface of the drive plate 51 is fixedly connected with a drive block 52. One side of the surface of the drive block 52 away from the surface of the drive plate 51 is fixedly connected with a limit block 521. The surface of the limit block 521 is cross-shaped. One side of the surface of the mounting plate 4 near the drive plate 51 is provided with a sliding space 41. The inner wall of the sliding space 41 abuts against a drive seat 53, so that the drive seat 53 can slide inside the sliding space 41. The side of the drive block 52 away from the drive plate 51 abuts against the side of the drive seat 53 near the drive plate 51. The side of the drive seat 53 near the drive plate 51 is provided with a limiting groove 531 that is adapted to the limiting block 521. The surface of the limiting block 521 abuts against the inner wall of the limiting groove 531, so that the limiting block 521 can slide stably inside the limiting groove 531. The side of the drive seat 53 near the sealing plate 2 is fixedly connected to the drive frame 54. The side of the drive frame 54 is L-shaped. The inner wall of the sliding space 41 is provided with an active space 42. The side of the drive frame 54 near the drive seat 53 abuts against the inner wall of the active space 42, so that the side of the drive frame 54 near the drive seat 53 can slide stably inside the active space 42. The drive frame 54 is fixedly connected to the side of the surface away from the drive seat 53 on the side of the sealing plate 2 away from the scraper 3. The mounting plate 4 is fixedly connected to the side of the surface near the sealing plate 2 with a mounting box 58. A limiting space 581 is opened on the side of the mounting box 58 near the sealing plate 2. The inner wall of the limiting space 581 abuts against the surface of the sealing plate 2, so that the sealing plate 2 can move into the interior of the mounting box 58 through the limiting space 581. The inner wall of the limiting space 581 abuts against the surface of the drive frame 54.

[0032] Manually pull the drive plate 51 to move it from top to bottom. The drive plate 51 drives the drive block 52 to move, the drive block 52 drives the limit block 521 to move, the limit block 521 drives the drive seat 53 to move, the drive seat 53 drives the drive frame 54 to move, the drive frame 54 drives the sealing plate 2 to move, and the sealing plate 2 drives the scraper 3 to move, thus achieving simultaneous driving of the sealing plate 2 and the scraper 3. When the drive plate 51 is pulled upward, the drive plate 51 can drive the sealing plate 2 and the scraper 3 to move upward at the same time, releasing the sealing plate 2 from the nozzle 11, so that the car handrail can be sprayed with glue through the manual glue spraying machine body 1 and the nozzle 11.

[0033] Reference Figures 5-7The drive plate 51 is symmetrically fixedly connected with positioning posts 57 for positioning the drive plate 51 on the side of the surface near the mounting plate 4. The mounting plate 4 is symmetrically provided with a plurality of positioning holes 43 that are adapted to the positioning posts 57 on the side of the surface near the drive plate 51.

[0034] Before the drive plate 51 is manually pulled, it is first manually pushed away from the surface of the mounting plate 4, so that the drive plate 51 is away from the surface of the mounting plate 4. This causes the drive plate 51 to drive the positioning pin 57 to disengage from the interior of the positioning hole 43. When the positioning pin 57 is completely disengaged from the interior of the positioning hole 43, the positioning pin 57 releases its positioning of the drive plate 51, allowing the drive plate 51 to be driven by external force to move from top to bottom, thereby controlling the movement state of the sealing plate 2 and the scraper 3.

[0035] When the positioning pin 57 moves to the positioning hole 43 located above one side of the surface of the mounting plate 4, the user manually pushes the drive plate 51 along the surface of the mounting plate 4, so that the drive plate 51 is close to the surface of the mounting plate 4. The drive plate 51 drives the positioning pin 57 to be close to the mounting plate 4, so that the positioning pin 57 is inserted into the positioning hole 43 located above one side of the surface of the mounting plate 4 to position the drive plate 51, so that the drive plate 51 will not move downward before the positioning is released.

[0036] Reference Figures 3-8 An installation cylinder 56 is fixedly connected inside the installation box 58. A sliding groove 542 is opened on the surface of the drive frame 54. The surface of the installation cylinder 56 abuts against the inner wall of the sliding groove 542, so that the drive frame 54 can slide on the surface of the installation cylinder 56. A spring 55 is fixedly connected to the top wall of the installation box 58. The installation cylinder 56 is sleeved on the outer surface of the spring 55. An installation block 543 is fixedly connected to one end of the spring 55 near the drive frame 54. A connecting block 544 is symmetrically fixedly connected to the surface of the installation block 543. The end of the connecting block 544 away from the installation block 543 is fixedly connected to the drive frame 54. A sliding groove 561 that matches the connecting block 544 is symmetrically opened on the surface of the installation cylinder 56. The surface of the connecting block 544 abuts against the inner wall of the sliding groove 561, so that the connecting block 544 can slide stably inside the sliding groove 561.

[0037] It should be noted that the calculation formula for spring 55 is: F=kx, where F is the external force acting on spring 55, in N, k is the spring constant of spring 55, in N / m, and x is the deformation of spring 55, in m. The elastic force of spring 55 is then calculated so that it can be used in this application.

[0038] During the upward movement of the drive frame 54, the drive frame 54 drives the sealing plate 2 to move upward while simultaneously driving the connecting block 544 to move upward. The connecting block 544 drives the mounting block 543 to move upward, and the mounting block 543 presses the spring 55, causing the spring 55 to deform. When it is necessary to seal the nozzle 11, the user only needs to manually push the drive plate 51 away from the surface of the mounting plate 4, so that the drive plate 51 is disengaged from the positioning hole 43 located above one side of the surface of the mounting plate 4. When the drive plate 51 is completely disengaged from the positioning hole 43 located above one side of the surface of the mounting plate 4, the drive plate 51 loses its positioning, and the spring 55 loses its restraint, causing the spring 55 to recover its deformation. The mounting block 543 moves downward by the elastic force of the spring 55 recovering its deformation. The mounting block 543 drives the connecting block 544 to move upward, the connecting block 544 drives the drive frame 54 to move upward, the drive frame 54 drives the sealing plate 2 to move downward, and the sealing plate 2 drives the scraper 3 to move downward, thereby scraping off the residual glue on the surface of the nozzle 11 and sealing the nozzle 11, realizing the rapid sealing and glue removal of the nozzle 11.

[0039] Reference Figures 5-8 Inside the mounting box 58, guide rods 6 are symmetrically fixedly connected. The guide rods 6 are used to guide the drive frame 54. One side of the surface of the drive frame 54 is symmetrically provided with guide grooves 541 that are adapted to the guide rods 6. The surface of the guide rods 6 abuts against the inner wall of the guide grooves 541, so that the drive frame 54 can slide stably under the guidance of the guide rods 6, and prevent the drive frame 54 from deviating during the sliding process.

[0040] The guide rod 6 guides the drive frame 54 during its movement to prevent the drive frame 54 from deviating during movement.

[0041] Reference Figures 2-5 The scraper 3 has a collection box 7 on the side away from the sealing plate 2. The side of the collection box 7 near the scraper 3 is set as an inclined surface with an inclination angle of 30-45°. When a 40° inclined surface is used, the residual amount of medium viscosity glue is only 0.05mg / cm², and the flow guiding efficiency is over 98%. The side of the collection box 7 near the scraper 3 does not need to be enlarged to adapt to the flow rate. A pusher 71 for driving the collection box 7 to move is fixedly connected to one side of the surface of the collection box 7. The surface of the pusher 71 from top to bottom is U-shaped, which makes it easy to pull the pusher 71. A mounting base 8 for mounting the collection box 7 is fixedly connected to the side of the mounting plate 4 near the sealing plate 2. A mounting groove 81 for mounting the collection box 7 is opened on one side of the surface of the mounting base 8.

[0042] It should be noted that the surface of the collection box 7 and the inner wall of the mounting groove 81 are both provided with anti-slip texture to prevent the collection box 7 from falling out of the mounting groove 81. The width of the collection box 7 is 25-35mm, the height is 30-40mm, and the length is longer than the diameter of the nozzle 11 near the nozzle opening. The two sides of the inner wall of the collection box 7 are on the same vertical line as the surface of the nozzle 11 near the nozzle opening.

[0043] By pulling the pusher 71, the collection box 7 is moved so that it can be freely inserted into the mounting slot 81. The end of the collection box 7 with the bevel is moved away from the mounting plate 4, so that the collection box 7 can collect the glue scraped off by the scraper 3, reducing glue loss. The mounting seat 8 limits the collection box 7 to prevent it from sliding freely after being inserted into the mounting slot 81.

[0044] It should be noted that when the positioning pin 57 is inserted into the positioning hole 43 far away from the mounting base 8, the top surface of the drive base 53 abuts against the top wall of the sliding space 41, and the sealing plate 2 and scraper 3 enter the mounting box 58. When the positioning pin 57 is inserted into the positioning hole 43 close to the mounting base 8, the bottom surface of the drive base 53 abuts against the bottom wall of the sliding space 41, the bottom surface of the scraper 3 abuts against the inclined surface of the collection box 7, and the sealing plate 2 is in the state of sealing the nozzle 11.

[0045] It should be added that: the sealing plate 2 is made of silicone, the scraper 3 is made of polytetrafluoroethylene, the collection box 7 is made of double-layer vacuum PC (polycarbonate), and the inclined surface of the collection box 7 is made of polytetrafluoroethylene.

[0046] The implementation principle of the automotive armrest adhesive spraying device in this application embodiment is as follows: Before spraying adhesive, the sealing plate 2 and scraper 3 are driven upward by the drive mechanism 5. When the positioning post 57 in the drive mechanism 5 moves to be directly opposite the positioning hole 43, the drive plate 51 is manually pushed in the direction close to the surface of the mounting plate 4, so that the positioning post 57 is inserted into the positioning hole 43 located above the surface of the mounting plate 4, so that the positioning post 57 positions the drive plate 51. At the same time, the sealing plate 2 and scraper 3 enter the interior of the mounting box 58, so that the nozzle 11 is exposed, the sealing plate 2 is released from the nozzle 11, and the spring 55 is in a compressed state. Then the manual adhesive spraying machine body 1 is started, and the automotive armrest is sprayed with adhesive through the manual adhesive spraying machine body 1 and the nozzle 11. This adhesive spraying process belongs to the prior art, and the specific principle and process will not be described in detail.

[0047] After the adhesive is sprayed, the user manually pushes the drive plate 51 away from the mounting plate 4, causing the positioning post 57 to disengage from the positioning hole 43 and releasing the positioning of the drive plate 51. The sealing plate 2 and the scraper 3 can then move downwards quickly due to the elastic force of the spring 55, allowing the sealing plate 2 to quickly seal the nozzle 11, preventing air from entering the nozzle 11 and avoiding oxidation and curing of the adhesive inside the nozzle 11. The scraper 3 can also quickly scrape off the residual adhesive on the surface of the nozzle 11 and come into contact with the collection box 7, allowing the adhesive to be automatically guided into the collection box 7. This achieves the collection of residual adhesive on the surface of the nozzle 11, reducing the loss of adhesive due to residual curing or dripping, and lowering the cost of raw materials.

[0048] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
