Description

Technical Field

[0001] This utility model relates to the field of edge banding machine technology, specifically to a sheet extrusion device for a sheet edge banding machine. Background Technology

[0002] An edge banding machine is a highly automated machine that replaces manual edge banding processes: conveying, applying glue and attaching the edge, cutting, front and back trimming, top and bottom trimming, top and bottom fine trimming, top and bottom scraping, and polishing. It is mainly divided into semi-automatic and handheld types. The edge banding machine is a type of woodworking machinery. After applying glue and attaching the strips, the edge banding machine needs to use a board extrusion device to press and bond the strips. The board extrusion devices used in existing board edge banding machines still have certain defects in use, such as...

[0003] Publication number CN216941109U discloses a sheet metal extrusion device for a sheet metal edge banding machine, comprising a bonding wheel rotatably mounted on a table. The device is characterized by further including an auxiliary extrusion wheel, which is mounted on the table and positioned to one side of the bonding wheel. The extrusion wheel is mounted on the table via a mounting bracket, which is hinged or slidably mounted on the table. An elastic device is provided between the mounting bracket and the table, causing the auxiliary extrusion wheel to tend towards the sheet metal. This invention enhances the bonding effect between the edge banding tape and the sheet metal, improving the edge banding effect.

[0004] The aforementioned document describes the use of an elastic device to press an auxiliary extrusion roller onto the board material. However, the extrusion force of the auxiliary extrusion roller cannot be controlled. When the extrusion force is too small, it is difficult to achieve sufficient adhesion, and when the extrusion force is too large, it is easy to squeeze out the glue. Based on this, a board extrusion device for a board edge banding machine is proposed to solve the above problems. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The sheet metal extrusion device used in this sheet metal edge banding machine compresses air by rotating a worm gear to push a second piston, which then sends the air through a hose into a first air cylinder, increasing the air pressure inside the first air cylinder and adjusting the extrusion force of the extrusion wheel on the support arm. This allows the sheet metal extrusion device to control the extrusion force. The specific details are as follows:

[0017] 1.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4This utility model provides a technical solution: a sheet extrusion device for a sheet edge banding machine, comprising: a mounting plate 1, a bonding wheel 2, a first rotating shaft 3, and a support arm 4; the upper surface of the mounting plate 1 is rotatably connected to the bonding wheel 2 via the rotating shaft, the upper surface of the mounting plate 1 near the bonding wheel 2 is fixedly connected to the first rotating shaft 3, the support arm 4 is rotatably connected to the first rotating shaft 3, the other end of the support arm 4 is rotatably connected to an extrusion wheel 5, the back of the extrusion wheel 5 is connected to a reset mechanism 6, and a drying mechanism 7 is provided on one side of the extrusion wheel 5; the front part of the support arm 4 abuts against a positioning bolt 8, the positioning bolt 8 is threaded into a hole on the mounting plate 1; the reset mechanism 6 includes a second rotating shaft 601 connected to the upper surface of the mounting plate 1 near the back of the extrusion wheel 5, the second rotating shaft 601 is rotatably connected to a first air cylinder 602, the inner wall of the first air cylinder 602 is slidably connected to a first piston 603, the front part of the first piston 603 is connected to a first inner rod 604, the first... The inner rod 604 slides through the front part of the inner wall of the first air cylinder 602, and the first inner rod 604 is rotatably connected to the back of the support arm 4 via a lug. A hose 605 is connected to one side of the first air cylinder 602, and the other end of the hose 605 is connected to a second air cylinder 606. The second air cylinder 606 is bolted to the upper surface of the mounting plate 1. A second piston 607 is slidably connected to the inner wall of the second air cylinder 606, and a second inner rod 608 is connected to one side of the second piston 607. The second inner rod 608 slides through one side of the inner wall of the second air cylinder 606. A bracket 609 is bolted to one side of the second air cylinder 606. A threaded rod 610 rotates through the inner wall of the bracket 609. The threaded rod 610 is threaded into the second inner rod 608 through a threaded groove. A worm gear 611 is connected to the outside of the threaded rod 610. A worm 612 is meshed above the worm gear 611. The worm 612 rotates through the inner wall of the bracket 609.

[0028] In practice, the rotating worm 612 drives the worm wheel 611 to drive the threaded rod 610 to rotate inside the second inner rod 608, which in turn drives the second piston 607 to compress air. The air is then sent from the hose 605 into the first air cylinder 602, increasing the air pressure inside the first air cylinder 602. This pushes the first piston 603, which in turn drives the first inner rod 604 to rotate the support arm 4. The compression force of the extrusion wheel 5 on the support arm 4 is adjusted, allowing the sheet metal extrusion device to control the compression force.

[0029] See Figure 1 , Figure 2 , Figure 5 and Figure 6It is known that the drying mechanism 7 includes an insulated box 701 connected to the upper surface of the mounting plate 1 near the back of the extrusion roller 5. An air jet 702 is connected through the front of the inner wall of the insulated box 701, and a blower 703 is connected to one side of the insulated box 701. An electric heating ceramic plate 704 is abutted on the inner wall of the insulated box 701. A perforated heat-conducting plate 705 is connected to the inner wall of the electric heating ceramic plate 704. An insulated cover 706 is abutted above the electric heating ceramic plate 704. The insulated cover 706 is bolted to the inner wall of the insulated box 701.

[0030] In practice, the electric heating ceramic plate 704 is energized and heated, and the heat is transferred to the hollow heat-conducting plate 705. The blower 703 sends outside air into the heat preservation box 701. The electric heating ceramic plate 704 guides the air entering the heat preservation box 701, increases the flow path, and heats it. Then it is blown out from the air jet 702 to heat the edge-sealed board and accelerate the drying of the glue. The board extrusion device assists in the drying process.

[0031] In summary: When using this type of sheet extrusion device for a sheet edge banding machine, firstly, the device is installed on the edge banding machine with threads, positioned on one side of the strip attaching assembly. Then, the blower 703 and the electric heating ceramic plate 704 are connected to the control system of the edge banding machine. The worm gear 612 is rotated to adjust the extrusion force of the extrusion wheel 5. The heating temperature of the electric heating ceramic plate 704 and the air force of the blower 703 are adjusted using the control system of the edge banding machine. After the sheet is coated with adhesive and attached, it is initially bonded by the rolling of the attaching wheel 2, and then abuts against the extrusion wheel 5. This drives the support arm 4 to rotate, pushing the first inner rod 604 and the first piston 603 to compress the air in the first air cylinder 602. The reaction force of the air in the first air cylinder 602 pushes the support arm 4 to rotate, pressing the extrusion wheel 5 onto the edge banding strip on the sheet, thus bonding the edge banding strip to the sheet. Then, hot air is blown from the front of the air jet 702 to accelerate the drying of the adhesive. The contents not described in detail in this description are existing technologies known to those skilled in the art.
