Description

Technical Field

[0001] This utility model relates to the field of board cleaning technology, specifically to a board washing machine. Background Technology

[0002] In the furniture manufacturing industry, board cleaning plays a crucial role in ensuring product quality. Currently, ordinary cleaning equipment on the market can only remove general EVA glue and dust. With the development of furniture manufacturing processes, the application of PUR glue in the processing is becoming increasingly widespread. After PUR glue processing and edge banding, various complex contaminants, including dust, glue, and dirt, remain on the board surface. Ordinary cleaning equipment cannot effectively handle these contaminants, leading to a decrease in the quality of furniture boards leaving the factory and negatively impacting product quality. Although some innovative solutions have emerged, such as the multi-faceted board washing machine (application number CN2021209177002) and the automated board cleaning production line (CN202122739283X), these devices have achieved a certain degree of automated cleaning of EVA glue and dust, bringing convenience to board cleaning in furniture manufacturing. However, these board washing machines still have certain shortcomings, specifically:

[0003] 1. The cleaning machine body is connected to the board feeding roller conveyor and the board discharging roller conveyor using a linear fixed connection method. This connection method brings many inconveniences to long-distance transportation. During transportation, due to the lack of flexibility in the connection structure, the equipment is easily damaged by vibration, collision, etc., which not only increases transportation costs, but also requires additional maintenance and debugging after transportation to ensure its normal installation and use.

[0004] 2. The cleaning unit is equipped with a double-sided board cleaning device, a double-sided board washing device, and a longitudinal board cleaning device. However, when processing boards using PUR glue, this device cannot completely remove the PUR glue from the board surface. Residual glue may result in uneven surfaces and easy dust accumulation, seriously affecting the overall quality and aesthetics of the furniture products. Utility Model Content

[0005] In view of this, the present invention proposes a plate washing machine that connects the plate supply roller conveying device, the plate discharge roller conveying device, and the cleaning machine body in a foldable manner to facilitate long-distance transportation.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A plate washing machine includes a frame and a cleaning body mounted on the frame. The plate feeding end of the frame is foldably connected to a plate feeding roller conveying device, which is used to input the plate to be cleaned into the cleaning body. The plate output end of the frame is foldably connected to an output plate conveying device, which is used to push the cleaned plate output from the cleaning body forward.

[0008] To better implement the above technical solution, optionally, the feeding roller conveying device includes a first conveying roller frame and a second conveying roller frame. The two sides of one end of the first conveying roller frame are respectively foldably connected to the two sides of the plate inlet end of the frame. The two sides of the other end of the first conveying roller frame are respectively foldably connected to the two sides of one end of the second conveying roller frame. The first conveying roller frame has first support legs that can be folded at a certain angle on both sides of the end connected to the second conveying roller frame. The second conveying roller frame has second support legs that can be folded at a certain angle on both sides of the end away from the first conveying roller frame. When the first support legs and the first support legs are folded, the first conveying roller frame and the second conveying roller frame are simultaneously folded downwards at their connection points, so that the first support legs, the first conveying roller frame, the second conveying roller frame and the second support legs form a stacked structure that is tightly attached to the plate inlet end of the frame.

[0009] Optionally, the cleaning machine body includes a first double-sided polishing device, a first bidirectional brush strip device, a glue scraping device, a second bidirectional brush strip device, a unidirectional brush strip device, and a second double-sided polishing device arranged sequentially along the conveying direction of the plate.

[0010] Optionally, the cleaning body further includes a cleaning fluid supply device for supplying cleaning fluid to the first bidirectional brush strip device, the second bidirectional brush strip device, and the unidirectional brush strip device.

[0011] Optionally, the scraping device includes a mounting assembly and a scraper fixed to the mounting assembly at an adjustable mounting angle, the blade of the scraper being inclined forward in the board conveying direction.

[0012] Optionally, the mounting assembly is further provided with a scraper strip that fits against the scraper, the scraper strip being located on the front side of the scraper.

[0013] Optionally, the glue scraping device consists of two sets, which are symmetrically arranged along the conveying direction of the board, and the two scrapers of the two glue scraping devices form a horizontal V-shaped structure.

[0014] Optionally, it also includes a housing having an inlet and an outlet, wherein the frame and the cleaning body are both disposed within the housing.

[0015] Optionally, it also includes a dust collection device disposed within the housing, wherein at least one dust collection port of the dust collection device is disposed at the first double-sided polishing device.

[0016] The beneficial effects of this utility model are:

[0017] This utility model of a plate washing machine allows for the folding of the supply and discharge rubber roller conveying devices at both ends of the machine body during transportation. This significantly reduces the space occupied by the washing machine during transport, lowering transportation costs. Simultaneously, the foldable design avoids the risk of damage during transport due to the machine's large size, ensuring the integrity of the equipment during transit. In use, the supply and discharge rubber roller conveying devices can be unfolded, enabling the equipment to be quickly deployed at the site without complex installation processes, saving time and labor costs.

[0018] The board washing machine of this utility model can remove PUR glue from the surface of the board by setting a glue scraping device, thereby improving the cleaning effect of the board. Attached Figure Description

Detailed Implementation

[0028] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. Identical components are indicated by the same reference numerals.

[0029] Example 1

[0030] Please see Figures 1 to 3 This utility model discloses a plate washing machine, including a frame 100, a cleaning body 200, a plate supply roller conveying device 300, and a plate discharge roller conveying device 400. The cleaning body 200 is integrally assembled on the frame 100. The plate supply roller conveying device 300 is used to continuously supply plates 600 to be cleaned to the cleaning body 200. The plate discharge roller conveying device 400 is used to push the cleaned plates 600 in the cleaning body 200 forward.

[0031] Specifically, the board feeding roller conveyor 300 is installed in a foldable manner at the board feeding end of the frame 100, and the board output roller conveyor 400 is installed in a foldable manner at the board output end of the frame 100.

[0032] This utility model's plate washing machine allows for the folding of the supply roller conveyor 300 and the discharge roller conveyor 400 at both ends of the cleaning machine body 200 during transportation. This significantly reduces the space occupied by the washing machine during transport, lowering transportation costs. Simultaneously, the foldable design avoids the risk of damage during transport due to the washing machine's excessive size, ensuring the integrity of the equipment during transit. In use, the supply roller conveyor 300 and the discharge roller conveyor 400 can be unfolded, enabling the equipment to be quickly deployed at the site without complex installation processes, saving time and labor costs.

[0033] like Figure 3As shown, in this embodiment, the board feeding roller conveying device 300 includes a first conveying roller frame 310 and a second conveying roller frame 320. Both the first conveying roller frame 310 and the second conveying roller frame 320 include a square frame and rollers spaced apart within the square frame along the board conveying direction. The square frame and rollers have the same structure as in the prior art, and will not be described in detail here.

[0034] The two sides of one end of the first transmission roller frame 310 are foldably connected to the two sides of the inlet end of the frame 100. The two sides of the other end of the first transmission roller frame 310 are foldably connected to one side of the second transmission roller frame 320. The first transmission roller frame 310 has a first support leg 330 that can be folded at 90° on both sides of the end connected to the second transmission roller frame 320. The second transmission roller frame 320 has a second support leg 340 that can be folded at 90° on both sides of the end away from the first transmission roller frame 310. When the first support leg 330 and the first transmission roller frame 320 are folded, the first transmission roller frame 310 and the second transmission roller frame 320 are folded downwards at the connection point, so that the first support leg 330, the first transmission roller frame 310, the second transmission roller frame 320 and the second support leg 340 form a stacked structure that is tightly attached to the inlet end of the frame 100.

[0035] More specifically, the first transmission roller frame 310, the second transmission roller frame 320, and the frame 100 are all connected by a pivot folding arm assembly 350, allowing the first transmission roller frame 310 to rotate and fold around the pivot. The first support leg 330 and the second support leg 340 are connected to the corresponding square frame through a U-shaped plate 361 and a first connecting shaft 362. The U-shaped plate 361 is fixed on the square frame, and the first connecting shaft 362 is fixedly inserted through the upper end of the U-shaped plate 361 and the support leg. The first support leg 330 and the second support leg 340, which are installed using the U-shaped plate 361 and the first connecting shaft 362, can only rotate 90°. This not only ensures the structural stability after folding, but also allows the support leg to accurately return to the working position when the equipment is unfolded, providing stable support for the transmission roller frame.

[0036] In the embodiments of this utility model, the structure of the board output rubber roller conveying device 400 and the board supply rubber roller conveying device 300 are the same as those of the frame 100. Therefore, the structure of the board output rubber roller conveying device 400 will not be described in detail.

[0037] In embodiments of this utility model, a housing 500 is also included. The housing 500 has an inlet and an outlet. The frame 100 and the cleaning body 200 are both located inside the housing 500. The housing 500 can be equipped with multiple doors. The multiple doors greatly facilitate the maintenance of the cleaning body 200. If the cleaning body 200 malfunctions during equipment operation, maintenance personnel can quickly access the faulty component through these doors for inspection, repair, or replacement without disassembling the entire equipment. This greatly shortens maintenance time, reduces maintenance costs, and improves the maintainability of the equipment.

[0038] Example 2

[0039] Please see Figures 4 to 7 This embodiment is a further improvement on embodiment 1, specifically:

[0040] The cleaning machine 200 includes a first double-sided polishing device 210, a cleaning liquid supply device 220, a first bidirectional brush strip device 230, a glue scraping device 240, a second bidirectional brush strip device 250, a unidirectional brush strip device 260, and a second double-sided polishing device 270 arranged sequentially along the plate conveying direction.

[0041] In this embodiment, the structures of the first double-sided polishing device 210, the first bidirectional brush strip device 230, the second bidirectional brush strip device 250, the unidirectional brush strip device 260, and the second double-sided polishing device 270 are similar to those in the prior art (partially consistent with the corresponding structure in application number CN202122739283X), and will not be described in detail here.

[0042] In this embodiment, the cleaning body 200 also includes a cleaning liquid supply device 220, which is used to supply cleaning liquid to the first bidirectional brush strip device 230, the second bidirectional brush strip device 250 and the unidirectional brush strip device 260.

[0043] In this embodiment, the adhesive scraping device 240 includes a mounting assembly and a scraper 2445 fixed on the mounting assembly at an adjustable mounting angle. The blade of the scraper 2445 is inclined towards the front side in the board conveying direction.

[0044] like Figure 6 and Figure 7As shown, the frame 100 has two support plates 2410 arranged parallel to the plate conveying direction. The mounting components include a lifting adjustment seat 2420, a spring connecting rod 2430, and a scraper mounting seat. The lifting adjustment seat 2420 is a handwheel-driven threaded lifting seat. Each support plate 2410 is provided with a lifting adjustment seat 2420 in a linearly lifting manner. One end of the spring connecting rod 2430 is fixed to the seat plate of the lifting adjustment seat 2420, and the scraper mounting seat is movably sleeved on the other end of the spring connecting rod 2430. In this embodiment, each lifting adjustment seat 2420 is provided with two spring connecting rods 2430. An adjusting nut 2431 for adjusting the spring compression of the rod is screwed onto the rod body of the spring connecting rod 2430. The scraper mounting seat includes a strip base 2441, a screw clamping shaft seat 2442, a mounting shaft 2443, and a blade holder 2444. The strip base 2441 is sleeved on the spring connecting rod 2430 along the width direction of the plate. For example, the two ends of the strip-shaped base 2441 are each mounted on the lifting adjustment seat 2420 via two spring connecting rods 2430. The screw-clamping type bearing seat 2442 is fixed to the end side wall of the strip-shaped base 2441 by fixing screws. The screw-clamping type bearing seat 2442 fixes and holds the mounting shaft 2443. Both ends of the strip-shaped base are provided with screw-clamping type bearing seats 2442. The two ends of the tool holder 2444 are respectively fixedly connected to the mounting shaft 2443 by screws. 444 has a U-shaped structure. The bottom of the scraper 2445 is fixed inside the scraper holder 2444 by a screw. The scraper holder 2444 is also provided with a scraping strip 2446 that fits against the scraper 2445. The scraping strip 2446 is located on the rear side of the scraper 2445. During the assembly process, the angle of the mounting shaft 2443 can be adjusted by adjusting the fastening screw of the screw clamping type bearing 2442, thereby changing the installation angle of the scraper 2445 and the scraping strip 2446 to obtain the best scraping effect.

[0045] In the embodiments of this utility model, by setting an adjustable elastic spring connecting rod 2430, the scraper 2445 and the glue scraping strip 2446 can elastically scrape the glue during the glue scraping process, thereby ensuring the glue scraping effect while better protecting the board body and preventing excessive scraping.

[0046] In the embodiments of this utility model, there are two sets of glue scraping devices 240, which are symmetrically arranged along the conveying direction of the board. The two scrapers 2445 of the two glue scraping devices 240 form a horizontal V-shaped structure. The two sets of glue scraping devices 240 can simultaneously scrape off the excess glue on the upper and lower surfaces of the board.

[0047] In an embodiment of this utility model, a dust collection device 280 is also provided inside the housing 500. At least one dust collection port of the dust collection device 280 is provided at the first double-sided polishing device 210. By providing the dust collection device 280 inside the housing 500, it is possible to effectively prevent dust and other pollutants from spreading into the workshop environment during the dust collection process, thus maintaining the cleanliness and hygiene of the workshop.

[0048] This equipment uses multiple rubber rollers to transport the board to upper and lower brushes and multiple polishing structures to clean the surface dust, wood chips and other debris, and then collects them in a unified manner. Finally, the surface cleaning structure treats the surface dirt and glue particles, solving the problem of dust, debris, glue and dirt remaining on the surface of the board after processing.

[0049] The working principle of this plate washing machine:

[0050] The board 600 to be cleaned is automatically conveyed to the cleaning machine 200 by the board feeding roller conveyor 300. The first double-sided polishing device 210 initially polishes and cleans both sides of the board. The dust generated during polishing is collected by the dust collection device 280. Then, the first bidirectional brush strip device 230 brushes the board 600 to be cleaned, and the glue scraping device 240 scrapes off the glue residue on the surface of the board 600 to be cleaned. The second bidirectional brush strip device 250 brushes again, and the unidirectional brush strip device 260 and the second double-sided polishing device 270 polish again. All the pollutants generated are collected by the dust collection device 280.

[0051] The technical solution of this utility model has been described in detail above with reference to specific embodiments. The specific embodiments described are used to help understand the concept of this utility model. Derivations and modifications made by those skilled in the art based on the specific embodiments of this utility model also fall within the protection scope of this utility model.
