[0001] The utility model relates to the technical field of panel furniture packaging, in particular to an edge scraping mechanism used in an edge banding machine for panel furniture. Background Art

[0002] Panel furniture, also known as board furniture, is a type of furniture that uses board as the main structural material. In the manufacturing process of panel furniture, the edge banding process can enhance the appearance and waterproof ability of panel furniture. It is an indispensable production process in panel furniture. In order to keep the edge of the board smooth after edge banding, it is necessary to scrape off the excess glue on the edge banding.

[0003] The Chinese patent "A glue scraping device for edge banding machine" authorization announcement number "CN215198433U" installs the glue scraping component on the edge banding machine platform to facilitate the glue scraping process on the board; an art blade is used to scrape off excess glue on the edge banding, which is inexpensive compared to traditional mechanical blades.

[0004] Although the excess glue on the edge banding can be cleaned with a utility knife, the thickness of the excess glue on the edge banding is unevenly distributed, resulting in thicker glue in some areas, which increases the difficulty of cleaning with the utility knife, thereby affecting the scraping effect of the glue.

[0005] Therefore, a scraping mechanism for a panel furniture edge banding machine is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a scraping mechanism for a panel furniture edge banding machine comprises: a mounting frame 1, a scraping device 2 is arranged on one side of the mounting frame 1; wherein the scraping device 2 comprises two mounting plates 201 slidably connected to one side of the mounting frame 1, the opposite ends of the two mounting plates 201 are fixedly connected to a first air storage box 202, the end of the first air storage box 202 is fixedly connected to a fixing plate 203, the end of the fixing plate 203 is installed with a first cleaning knife 204, the inner wall of the first air storage box 202 is slidably connected to a first piston rod 205, one end of the first piston rod 205 passes through the first air storage box 202, one side of the end of the first piston rod 205 is fixedly connected to a mounting frame 206, the end of the mounting frame 206 is installed with a second cleaning knife 207, and a driving assembly 208 is arranged on the surface of the mounting frame 1.

[0026] The inner wall of the mounting frame 1 is rotatably connected with a bidirectional screw rod, and the inner walls of the two mounting plates 201 are threadedly connected to the surface of the bidirectional screw rod. When scraping the plate, the bidirectional screw rod is rotated according to the thickness of the plate to make the two mounting plates 201 approach each other. When the two mounting plates 201 move to make the two first cleaning knives 204 fit with the surface of the plate, the rotation is stopped.

[0027] The device is installed on one side of the edge banding machine of panel furniture. When the plate moves horizontally and passes through the edge banding machine for edge banding, it will enter between the two first air storage boxes 202. At this time, the bottom end of the upper first cleaning knife 204 and the top end of the lower first cleaning knife 204 are in contact with the surface of the plate. There is a certain gap between the upper second cleaning knife 207 and the lower second cleaning knife 207 and the plate. After the plate is edge-sealed and moves horizontally, the two second cleaning knives 207 will clean the thicker glue once, and the two first cleaning knives 204 will clean the surface of the plate for a second time.

[0028] like Figure 2 , Figure 3 and Figure 4As shown, the driving assembly 208 includes a second air storage box 2081 fixedly connected to the surface of the mounting frame 1, a motor 2082 fixedly connected to the top of the second air storage box 2081, a second piston rod 2083 slidably connected to the inner wall of the second air storage box 2081, a first spring 2084 fixedly connected to the top of the second air storage box 2081, a trigger plate 2085 fixedly connected to the top of the first spring 2084, the top of the second piston rod 2083 sequentially penetrates the second air storage box 2081 and the first spring 2084 and is fixedly connected to the bottom end of the trigger plate 2085, a cam 2086 fixedly connected to the output shaft of the motor 2082, an air guide pipe 2087 fixedly connected to the bottom end of the second air storage box 2081, and a connecting pipe 2088 is provided between the air guide pipe 2087 and the first air storage box 202. A second spring 2089 is fixedly connected to the other side of the first piston rod 205, and the other end of the second spring 2089 is fixedly connected to the inner wall of the first air storage box 202. The surface of the cam 2086 fits with the top of the trigger plate 2085. The middle part of the connecting pipe 2088 is a hose.

[0029] When the two first cleaning knives 204 and the two second cleaning knives 207 are cleaning, the motor 2082 in the driving assembly 208 is started, and gas is stored in the second gas storage box 2081. When the motor 2082 is started, the cam 2086 is driven to rotate, and the rotation of the cam 2086 pushes the trigger plate 2085. When the cam 2086 rotates from the lowest point to the highest point and contacts the top of the trigger plate 2085, the cam 2086 pushes the trigger plate 2085 to move downward. At this time, the first spring 2084 is compressed, and when the trigger plate 2085 moves downward, it pushes the second piston rod 2083 to move downward synchronously and squeeze the gas in the second gas storage box 2081. After being squeezed, the gas enters the air guide pipe 2087 and enters the two first storage boxes at the same time through the connecting pipe 2088. In the air box 202, the first piston rod 205 is pushed to move, and the second spring 2089 is pulled up. When and under the action of the mounting frame 206, the second cleaning knife 207 is driven to move. When the cam 2086 rotates from the highest point to the lowest point and contacts the top of the trigger plate 2085, the trigger plate 2085 drives the second piston rod 2083 to reset under the action of the first spring 2084, and the gas in the second air storage box 2081 loses its extrusion. At this time, the gas in the first air storage box 202 flows back into the second air storage box 2081, and under the action of the second spring 2089, the first piston rod 205 drives the second cleaning knife 207 to reset. Therefore, when the driving assembly 208 is running, it will drive the second cleaning knife 207 to move back and forth laterally, thereby improving the cleaning effect of thicker glue.

[0030] like Figure 5As shown, a round rod 20810 is fixedly connected to the surface of the fixed plate 203, and a cleaning plate 20811 is fixedly connected to the other end of the round rod 20810. The vertical section of the cleaning plate 20811 is a right triangle, and the right angle side of the cleaning plate 20811 fits the surface of the second cleaning knife 207. The bottom end of the upper second cleaning knife 207 contacts the top end of the cleaning plate 20811, and the top end of the lower second cleaning knife 207 contacts the bottom end of the cleaning plate 20811. When the two second cleaning knives 207 move back and forth horizontally, the cleaning plate 20811 will clean the glue scraped off the two second cleaning knives 207.

[0031] like Figure 2 As shown, the inner wall of the first air storage box 202 is fixedly connected to a limit frame 20812, and the limit frame 20812 is arranged on the other side of the first piston rod 205. When the first piston rod 205 is reset and moved, when the other side is in contact with the limit frame 20812, the first piston rod 205 cannot move further.

[0032] When the utility model is used, when cleaning the excess glue on the edge of the plate, the distance between the two mounting plates 201 is adjusted. After the edge of the plate is sealed, in the process of horizontal movement, the two second cleaning knives 207 will clean the thicker glue once, and the two first cleaning knives 204 will clean the surface of the plate twice. At the same time, the motor 2082 in the drive assembly 208 is started to drive the cam 2086 to rotate, and under the action of the first spring 2084, the trigger plate 2085 will drive the second piston rod 2083 to move up and down reciprocatingly. When the second piston rod 2083 moves downward, , squeeze the gas in the second gas storage box 2081, enter the two first gas storage boxes 202 through the air guide pipe 2087 and the connecting pipe 2088 at the same time, and push the first piston rod 205 to drive the second cleaning knife 207 to move. When the second piston rod 2083 moves upward, the gas in the first gas storage box 202 flows back to the second gas storage box 2081, and under the action of the second spring 2089, the first piston rod 205 drives the second cleaning knife 207 to reset. Therefore, when the driving component 208 is running, it will drive the second cleaning knife 207 to move horizontally and reciprocatingly to improve the cleaning effect of thicker glue. The cleaning effect of thicker glue is improved.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
