Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive coating device technology, and more specifically, to an adhesive coating device for PVC surface. Background Technology
[0002] In the processing of PVC sheets, PVC materials need to be bonded together with other materials, which requires an adhesive applicator to apply adhesive to the surface of the PVC sheets to facilitate subsequent bonding. For example, a PVC composite board adhesive applicator is disclosed in patent publication number CN219187503U. It includes a conveyor belt for placing PVC composite boards, a gantry frame is provided on the left and right side plates of the conveyor belt, a U-shaped seat is provided on the inner side of the two vertical plates of the gantry frame, a lifting component is provided on the inner side of the two vertical plates of the gantry frame to drive the U-shaped seat to move up and down, an adhesive applicator roller is provided between the two vertical plates of the U-shaped seat, a rotating component is provided inside the U-shaped seat to drive the adhesive applicator roller to rotate, and a glue feeding component is provided on the horizontal plate of the gantry frame to deliver glue to the adhesive applicator roller.
[0003] Although the above-mentioned glue-coating device can automatically convey and apply glue, the glue-coating structure needs to contact the PVC sheet to apply glue to its surface during the glue-coating process. This causes the PVC sheet to shift in position due to the contact between the glue-coating structure and the PVC sheet, resulting in a deviation in the glue-coating position of the PVC sheet. Therefore, we have made improvements to this and proposed a PVC surface glue-coating device. Utility Model Content
[0004] The main purpose of this invention is to provide a PVC surface adhesive coating device, which can effectively solve the problem of PVC board shifting during automatic adhesive coating, resulting in deviation in the adhesive coating position.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A PVC surface adhesive coating device includes a mounting frame. Conveyor belts for conveying PVC sheets are respectively arranged on both sides inside the mounting frame. A set of guide rails is arranged in the middle of the mounting frame. A support component for supporting the PVC sheets for adhesive coating is installed inside the guide rails. A set of slide rails is arranged on the outside of the mounting frame. An adhesive coating component for adhesive coating is installed on the outside of the slide rails.
[0007] Preferably, the adhesive application assembly includes a movable bracket, which is slidably mounted on the outside of the guide rail. A cylinder assembly is mounted on the upper end of the movable bracket, and a mounting frame is mounted on the output end of the cylinder assembly. An adhesive application roller for applying surface adhesive to the surface of the PVC sheet is rotatably mounted inside the mounting frame.
[0008] Preferably, a fixing rod is fixedly installed on one side of the coating roller, and an adhesive inlet is opened on the upper side of the mounting frame, with the adhesive inlet located on the upper side between the fixing rod and the coating roller.
[0009] Preferably, a screw hole is provided on one side of the movable bracket, and a drive motor is fixedly installed on one side of one of the slide rails. A drive screw is fixedly installed on the output end of the drive motor, and the body of the drive screw is threadedly engaged with the screw hole.
[0010] Preferably, the support assembly includes a movable frame, which is movably installed inside the guide rail. A vacuum pump is installed inside the movable frame. A set of support tubes is installed on the upper side of the movable frame. Each support tube is connected in series with a series pipe. Several vacuum suction cups are provided at the upper end of the support tube. One end of the vacuum pump is connected to the support tube, and the other end of the vacuum pump is located on one side of the movable frame.
[0011] Preferably, a control motor is fixedly installed at the bottom of the mounting frame, an adjusting screw is fixedly installed at the output end of the control motor, a threaded sleeve is fixedly installed at the lower end of the movable frame, and the adjusting screw and the threaded sleeve are threadedly engaged.
[0012] Preferably, an extension frame is fixedly installed in the middle of the mounting frame, and an infrared sensor for controlling the vacuum pump and controlling the start and stop of the motor is fixedly installed inside the extension frame. The infrared sensor, the vacuum pump and the control motor are connected by a controller signal.
[0013] Preferably, auxiliary plates are installed on both sides of the movable frame, and auxiliary rollers for supporting PVC sheets are rotatably installed on the upper end of the auxiliary plates.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] (1) The height of the coating roller can be adjusted by starting the cylinder group, so that the coating roller is in contact with the surface of the PVC board at the current position, thereby adapting to PVC boards of different thicknesses. Glue can be added by using the glue inlet, and since the glue inlet is located between the fixed rod and the coating roller, the glue will be concentrated on the upper side between the fixed rod and the coating roller. When the coating roller is passively rotated, its surface will absorb the glue and apply the glue to the surface of the PVC board under continuous rotation, thereby realizing automatic glue application.
[0016] (2) By controlling the vacuum pump to extract air from one end, the gas inside the support tube frame is extracted. Multiple support tube frames are discharged through a series of pipes, and vacuum suction cups are set on the support tube frames so that multiple vacuum suction cups can perform synchronous adsorption and fixation operations, so that the PVC board is temporarily fixed, and the glue application is stable during the automatic continuous glue application process, avoiding the glue application deviation caused by the displacement of the PVC board.
[0017] (3) By starting the control motor, the adjusting screw can be rotated. By using the limit cooperation between the guide rail and the movable frame, the position height of the movable frame will be adjusted when the adjusting screw body is threaded with the threaded sleeve. This allows the vacuum suction cup to adhere to the bottom of the PVC board and support the PVC board to cooperate with the glue roller for stable glue application. Attached Figure Description

Detailed Implementation
[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0025] like Figures 1 to 5 As shown, a PVC surface coating device includes a mounting frame 1. Conveyor belts 2 for conveying PVC sheets are respectively arranged on both sides inside the mounting frame 1. A set of guide rails 9 is arranged in the middle of the mounting frame 1, and a support component 3 for supporting the PVC sheets during coating is installed inside the guide rails 9. A set of slide rails 4 is arranged on the outer side of the mounting frame 1, and a coating component 5 for coating is installed on the outer side of the slide rails 4. The two sets of conveyor belts 2 can achieve continuous conveying of PVC sheets without the need for personnel to move the PVC sheets.
[0026] In this embodiment, the glue application assembly 5 includes a movable bracket 501, which is slidably mounted on the outside of the guide rail 9. A cylinder assembly 502 is mounted on the upper end of the movable bracket 501, and a mounting frame 503 is mounted on the output end of the cylinder assembly 502. A glue application roller 505 for applying surface glue to the surface of the PVC sheet is rotatably mounted inside the mounting frame 503.
[0027] A fixing rod 506 is fixedly installed on one side of the coating roller 505, and a glue inlet 504 is opened on the upper side of the mounting frame 503. The glue inlet 504 is located on the upper side between the fixing rod 506 and the coating roller 505.
[0028] The height of the coating roller 505 can be adjusted by activating the cylinder assembly 502, allowing the coating roller 505 to adhere to the surface of the PVC sheet at the current position, thus adapting to PVC sheets of different thicknesses. Glue can be added through the glue inlet 504, which is located between the fixing rod 506 and the coating roller 505. This causes the glue to concentrate on the upper side between the fixing rod 506 and the coating roller 505, so that the surface of the coating roller 505 absorbs the glue when it rotates passively, and applies the glue to the surface of the PVC sheet under continuous rotation, achieving automatic glue application.
[0029] The movable bracket 501 has a screw hole 7 on one side, and a drive motor 6 is fixedly installed on one side of a slide rail 4. A drive screw 8 is fixedly installed at the output end of the drive motor 6, and the body of the drive screw 8 is threadedly engaged with the screw hole 7.
[0030] By starting the drive motor 6, the drive screw 8 can be rotated. Utilizing the limiting engagement between the slide rail 4 and the moving bracket 501, the movement position of the moving bracket 501 is adjusted when the drive screw 8 body engages with the screw hole 7. This causes the glue roller 505 to passively rotate against the surface of the PVC sheet, thereby achieving automatic glue application.
[0031] In this embodiment, the support component 3 includes a movable frame 301, which is movably installed inside the guide rail 9. A vacuum pump 302 is installed inside the movable frame 301. A set of support tube frames 3021 is installed on the upper side of the movable frame 301. Each support tube frame 3021 is connected in series with a series pipe 3023. Several vacuum suction cups 3022 are provided on the upper end of the support tube frame 3021. One end of the vacuum pump 302 is connected to the support tube frame 3021, and the other end of the vacuum pump 302 is located on one side of the movable frame 301.
[0032] To prevent the PVC sheet from shifting during the adhesive application process, a vacuum pump 302 is controlled to extract air from one end, causing the gas inside the support tube 3021 to be extracted. Multiple support tubes 3021 are connected in series via pipes 3023 to expel the gas. Vacuum suction cups 3022 are placed on the support tubes 3021, allowing multiple suction cups 3022 to perform synchronous adsorption and fixation operations, thus temporarily fixing the PVC sheet. This ensures stable adhesive application during the automatic continuous adhesive application process and prevents deviations in adhesive application caused by PVC sheet displacement.
[0033] In this embodiment, a control motor 307 is fixedly installed at the bottom of the mounting frame 1, and an adjusting screw 3071 is fixedly installed at the output end of the control motor 307. A threaded sleeve 3011 is fixedly installed at the lower end of the movable frame 301, and the adjusting screw 3071 and the threaded sleeve 3011 are threadedly engaged. By starting the control motor 307, the adjusting screw 3071 can be rotated. Utilizing the limiting engagement between the guide rail 9 and the movable frame 301, the position and height of the movable frame 301 are adjusted when the adjusting screw 3071 and the threaded sleeve 3011 are threadedly engaged. This allows the vacuum suction cup 3022 to adhere to the bottom of the PVC sheet and support the PVC sheet to facilitate stable glue application with the glue application roller 505.
[0034] The mounting bracket 1 has an extension bracket 305 fixedly installed in the middle. Inside the extension bracket 305 is an infrared sensor 306 for controlling the vacuum pump 302 and the motor 307. The infrared sensor 306, vacuum pump 302, and motor 307 are connected via a controller signal. The infrared sensor 306 can detect whether the PVC sheet is in place, and control the motor 307 to support the sheet upwards and control the vacuum pump 302 to fix the sheet, thereby further realizing automated glue application.
[0035] In this embodiment, auxiliary plates 303 are respectively installed on both sides of the movable frame 301, and auxiliary rollers 304 for supporting PVC sheets are rotatably installed on the upper end of the auxiliary plates 303. The auxiliary rollers 304 can be used to assist in supporting the bottom of the PVC sheets.
[0036] The working principle of this PVC surface coating device:
[0037] In use, the PVC sheet is first placed on the conveyor belt 2 and then conveyed by the conveyor belt 2. When the sheet passes the infrared sensor 306, the infrared sensor 306 sends a control signal to control the motor 307 to rotate.
[0038] The adjustment screw 3071 can be rotated by starting the control motor 307. The guide rail 9 and the movable frame 301 are in a limiting cooperation. When the adjustment screw 3071 is threaded into the threaded sleeve 3011, the position and height of the movable frame 301 will be adjusted, so that the vacuum suction cup 3022 can fit against the bottom of the PVC sheet and support the PVC sheet.
[0039] Then, the infrared sensor 306 sends a control signal to the vacuum pump 302 to extract air. By controlling the vacuum pump 302 to extract air from one end, the gas inside the support tube frame 3021 is extracted. The gas is discharged from multiple support tube frames 3021 through the series pipe 3023. The vacuum suction cups 3022 are set on the support tube frames 3021, so that multiple vacuum suction cups 3022 can perform synchronous adsorption and fixation operations, so that the PVC sheet is temporarily fixed.
[0040] Then, by starting the cylinder group 502, the height of the glue-applying roller 505 can be adjusted, so that the glue-applying roller 505 is in contact with the surface of the PVC sheet at the current position. Starting the drive motor 6 can make the drive screw 8 rotate. By utilizing the limiting cooperation between the slide rail 4 and the moving bracket 501, the moving bracket 501 will be adjusted when the drive screw 8 is threaded into the screw hole 7, so that the glue-applying roller 505 will be passively rotated in contact with the surface of the PVC sheet, thereby realizing the automatic glue-applying operation.
[0041] After the glue application is completed, the vacuum pump 302 takes in air to release the vacuum suction cup 3022 from the board, and the control motor 307 reverses to reset the moving bracket 501, so that the board is placed on the conveyor belt 2 again. Finally, the board is sent out by the conveyor belt 2 to complete the automatic glue application.
[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
