Description

Technical Field

[0001] This utility model relates to the technical field of PVC sheet processing equipment, and in particular to a glue coating device for PVC sheet processing. Background Technology

[0002] PVC sheets, as a type of sheet material primarily composed of polymers, play an important role in interior decoration, equipment protection, and other applications. Compared to traditional sheets, PVC sheets offer advantages such as wear resistance, water resistance, and ease of cleaning. During the production of PVC sheets, adhesive is often applied to the back to facilitate installation. Specialized adhesive application equipment for PVC sheets is typically used to improve the adhesive application process.

[0003] To address this, patent specification CN212468677U discloses a gluing device for PVC sheet processing, comprising an outer casing and a control switch. The control switch is fixedly installed on the upper right side of the outer casing. A paint storage tank is fixedly installed on the upper inside of the outer casing. An electrically controlled valve is fixedly installed on the lower left inside the paint storage tank. A paint discharge plate is fixedly connected to the bottom of the electrically controlled valve via a pipe. A guide roller is rotatably connected to the lower part of the outer casing via a bracket. A conveyor belt is fixedly installed on the outer side of the guide roller. A servo motor is fixedly installed on the lower inside of the outer casing. A moving groove is provided at the upper opening inside the outer casing. A pressure spring is fixedly connected to the upper inside of the moving groove. A lower pressure plate is embedded in the lower inside of the moving groove. A rotating roller is rotatably connected to the bottom of the lower pressure plate. A hydraulic push rod is fixedly installed on the left side of the bottom of the lower pressure plate. This invention provides more uniform gluing, reduces glue waste during the gluing process, and provides greater gluing force and better results. While the above-mentioned gluing device has good gluing effects on PVC sheets, some problems still exist:

[0004] When the above-mentioned PVC sheet processing adhesive device is in use, the PVC sheets are prone to absorbing dust, lint and other impurities during stacking and storage and pre-processing. If these impurities are not removed during the subsequent spraying process, the adhesive coating on the PVC sheet surface will be uneven. Utility Model Content

[0005] The purpose of this invention is to provide a gluing device for PVC sheet processing, which solves the defect of uneven gluing caused by dust adsorption in existing PVC sheet gluing devices.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a gluing device for processing PVC sheets, including a base and a gluing chamber. A control box is installed on one side of the base, and a conveyor belt is fixedly connected to the top of the base. A gluing chamber is provided on one side above the conveyor belt, and an auxiliary structure is provided on the other side above the conveyor belt. The auxiliary structure includes a first side plate, a second side plate, a first support rod, a connecting frame, a scraper, a second support rod, rollers, a side frame, a spring, and a slider. The first side plate is fixedly connected to one side of both ends of the conveyor belt. A storage tank is installed at the top of the gluing chamber. A limit structure is provided on one side of the gluing chamber. A pump box is installed at the top inside the gluing chamber. A lifting frame is provided below the pump box, and gluing rollers are rotatably connected to both sides of the bottom of the lifting frame.

[0007] In use, when the gluing device is in operation, the PVC sheet is placed above the starting conveyor belt, and the conveyor belt moves the PVC sheet towards the inside of the gluing chamber. Since the inside of the gluing chamber is equipped with a lifting frame that can drive the gluing roller to move up and down, the distance between the gluing roller and the PVC sheet is adjusted during the gluing operation. The relevant pump inside the pump box draws special glue from the storage tank and sprays it onto the surface of the gluing roller. As the PVC sheet moves, the gluing roller gradually rolls and applies the glue adsorbed on the surface of the PVC sheet.

[0008] Preferably, the limiting structure includes a support plate, a bidirectional threaded rod, a guide rod, an internal threaded sleeve, and an arc-shaped traction plate. The support plate is fixedly connected to both ends of the conveyor belt. One end of the support plate is rotatably connected to the bidirectional threaded rod. A guide rod is provided below the bidirectional threaded rod. An internal threaded sleeve is wrapped around the outside of the guide rod. An arc-shaped traction plate is fixedly connected to the bottom of the internal threaded sleeve. The spacing between the two sets of arc-shaped traction plates is adapted to the width of the PVC sheet, so as to keep the PVC sheet stable during the conveying process.

[0009] Preferably, the bidirectional threaded rod and the internal threaded sleeve are threadedly connected, and the guide rod and the internal threaded sleeve are slidingly connected, thereby allowing the spacing of the two sets of arc-shaped traction plates to be adjusted.

[0010] Preferably, the arc-shaped traction plates are symmetrically distributed on the inner side of the conveyor belt about the vertical center line of the guide rod, so as to enable the PVC sheet to move smoothly.

[0011] Preferably, a second side plate is provided on one side of the first side plate, a first support rod is passed through the interior of the second side plate, a connecting frame is fixedly connected to the lower part of the first support rod, a scraper is installed at the bottom of the connecting frame, a second support rod is passed through the interior of the first side plate, a roller is rotatably connected to the outer side of the second support rod, a side frame is fixedly connected to one end of the first side plate and the second side plate, a spring is fixedly connected to the top of the interior of the side frame, and a slider is provided inside the spring. When the PVC sheet is conveyed, the bottom of the scraper will be in close contact with the glued surface of the PVC sheet under the elastic pressure of the spring. As the PVC sheet is conveyed, the scraper will scrape off the dust, lint and other debris adsorbed on the surface of the PVC sheet.

[0012] Preferably, a plurality of rollers are rotatably connected to the outside of the second support rod, and the plurality of rollers are distributed at equal intervals on the outside of the second support rod, so that the movement of the PVC sheet is not easily shaken.

[0013] Preferably, the side frame and the slider have a sliding structure, so that the scraper can scrape away debris from the surface of the board.

[0014] Compared with the prior art, the beneficial effects of this utility model are: when the submersible device is used, the PVC sheet is conveyed by the conveyor belt towards the interior of the coating chamber, and during the conveying process, the dust and lint adsorbed on the surface of the PVC sheet are scraped off by the scraper, so as to avoid uneven application of glue on the surface of the PVC sheet. Under the traction of the arc traction plate, it is conveyed along the center line of the conveyor belt into the interior of the coating chamber, so as to avoid the PVC sheet being conveyed too far off-center and causing material blockage when the conveying is long.

[0015] 1. During the conveying of PVC sheets, the bottom of the scraper will be in close contact with the glued surface of the PVC sheet under the elastic pressure of the spring. As the PVC sheet is conveyed, the scraper will scrape off the dust, lint and other debris adsorbed on the surface of the PVC sheet.

[0016] Furthermore, to prevent the PVC sheets from warping or shaking during conveying and surface cleaning, several rollers are rotatably connected to the outside of the second support rod to press the conveyed PVC sheets.

[0017] 2. By rotating the bidirectional threaded rod, the two sets of internal threaded sleeves drive the arc-shaped traction plates to move in opposite directions, and the distance between the two sets of arc-shaped traction plates is adapted to the width of the PVC sheet, so as to keep the PVC sheet stable during the conveying process.

A storage tank 5 is installed at the top of the gluing chamber 4. A pump box 8 is installed at the top inside the gluing chamber 4. A lifting frame 9 is located below the pump box 8. Glue rollers 10 are rotatably connected to both sides of the bottom of the lifting frame 9. A limit structure 6 is provided on one side of the gluing chamber 4. The limit structure 6 includes a support plate 601, a bidirectional threaded rod 602, a guide rod 603, and an internal threaded sliding sleeve 604. 4. An arc-shaped traction plate 605 and a support plate 601 are fixedly connected to both ends of the conveyor belt 3. One end of the support plate 601 is rotatably connected to a bidirectional threaded rod 602. A guide rod 603 is provided below the bidirectional threaded rod 602. An internal threaded sleeve 604 is wrapped around the outside of the guide rod 603. An arc-shaped traction plate 605 is fixedly connected to the bottom of the internal threaded sleeve 604. The bidirectional threaded rod 602 and the internal threaded sleeve 604 are threadedly connected. The guide rod 603 and the internal threaded sleeve 604 are sliding. The arc-shaped traction plate 605 is symmetrically distributed on the inner side of the conveyor belt 3 about the vertical center line of the guide rod 603.

[0026] See attached document Figure 1 and Figure 2 When the PVC sheet is long, it is easy for the PVC sheet to become skewed and collide with and be squeezed against the inner wall of the conveyor belt 3 as it is conveyed by the conveyor belt 3, which can lead to PVC sheet blockage. To address this, a bidirectional threaded rod 602 is rotatably connected to the inner side of the support plate 601. By rotating the bidirectional threaded rod 602, the two sets of internal threaded sleeves 604 drive the arc-shaped traction plates 605 to move in opposite directions, and the distance between the two sets of arc-shaped traction plates 605 is adapted to the width of the PVC sheet, so that the PVC sheet remains stable during the conveying process.

[0028] See attached document Figure 1 , Figure 4 and Figure 5 When the conveyor belt 3 transports the PVC sheet into the coating chamber 4, in order to avoid the PVC sheet surface from absorbing dust, lint, and other debris, which would lead to uneven coating of the PVC sheet, a first side plate 701 and a second side plate 702 are respectively set on one side above the conveyor belt 3. The first support rod 703 and the second support rod 706 are fixed to different sliders 710. When the PVC sheet is transported, under the elastic pressure of the spring 709, the bottom of the scraper 705 will be in close contact with the coating surface of the PVC sheet.
