Technical Field

[0001] The invention relates to the technical field of furniture production, in particular to a special glue dispensing head for thickness-fixing and gluing backboards in the furniture industry. Background Art

[0002] In traditional furniture production, such as cabinets, the back panels are usually divided into two parts due to the size of the packaging box. The back panels are packed in two parts by gluing them together with high-strength adhesive tape, but the adhesive strength is limited and the durability is poor.

[0003] The price of high-strength tape used for back panel bonding is much higher than that of ordinary tape. In addition, due to the limitations of the tape itself, it has poor adaptability to temperature and humidity, and its lifespan is unstable. In certain circumstances, adhesive failure may occur.

[0004] In the process of industrial mass production, due to the actual situation that the workpieces are relatively light and thin, the batch size is small, and the size varies a lot, from the perspective of economic benefits, this process is generally completed by hand.

[0005] There are risks of transportation quality during transportation. Due to the mutual contact and bumps between the workpieces, the tape may be partially detached from the workpieces, resulting in unsatisfactory results when the final consumer assembles the furniture.

[0006] In order to improve product quality and automation level, PUR glue is used to bond the two workpieces together. Summary of the invention

In addition, please understand that terms such as "first", "second", "third", "upper", "lower", "front", "rear", "inner", "outer", "end", "portion", "segment", "width", "thickness", "region" and the like in the text are only for the convenience of readers to refer to the structures in the drawings and are only used to help describe the present invention, and are not limitations of the present invention.

[0030] See also Figure 1-6 The present invention provides a technical solution: a special glue dispensing head for thickness-fixed bonding of back panels in the furniture industry, comprising a glue feed block 1. In order to install a glue outlet block 9 on the top of the glue feed block 1, the glue feed block 1 is composed of a base 2 and a first vertical plate 3 and a second vertical plate 4. The first vertical plate 3 and the second vertical plate 4 are respectively integrally formed at the two ends of the top of the base 2. The glue outlet block 9 is installed between the first vertical plate 3 and the second vertical plate 4 through a positioning pin 12 and a locking screw 13. The glue outlet block 9 is installed between the first vertical plate 3 and the second vertical plate 4 through a bolt, which can fix the position of the first glue outlet groove 15 and the glue outlet hole 6, avoid the position of the glue outlet block 9 from shifting during glue coating, and facilitate disassembly and assembly.

[0031] In order to transport PUR glue from the glue inlet hole 5 to the first glue outlet groove 15, a glue inlet hole 5 is opened on one side of the glue inlet block 1, and a glue outlet hole 6 is opened in the middle of the top of the glue inlet block 1. The glue inlet hole 5 and the glue outlet hole 6 are connected, and the glue outlet hole 6 and the first glue outlet groove 15 are connected.

[0032] In order to connect the glue discharge block 9 and the glue inlet block 1, the glue discharge block 9 is installed on the top of the glue inlet block 1 through a positioning pin 12 and a locking screw 13. Positioning through holes 10 are provided at the four corners of the top of the glue discharge block 9, and threaded through holes 11 are provided in the middle of both sides of the top of the glue discharge block 9. Positioning holes 7 and threaded holes 8 are provided at the positions of the glue inlet block 1 at the bottom of the positioning through holes 10 and the threaded through holes 11, respectively. A positioning pin 12 is installed between the positioning through holes 10 and the positioning holes 7, and a locking screw 13 is installed between the threaded through holes 11 and the threaded holes 8 through threads. The glue discharge block 9 and the glue inlet block 1 are connected by the locking screw 13 and the positioning pin 12, which can limit the position of the glue discharge block 9 and avoid the position deviation of the glue discharge block 9 affecting the gluing effect. At the same time, it is convenient to disassemble and assemble, and it is convenient to clean the glue remaining in the first glue discharge groove 15 to avoid the first glue discharge groove 15 being blocked and affecting the service life.

[0033] In order to facilitate glue coating, a slope 16 is provided on the other side of the glue feeding block 1. The bottom of the slope 16 is inclined toward the inside of the glue feeding block 1. The slope 16 does not contact the back plate, reducing friction and facilitating glue coating in the second glue outlet groove 14.

[0034] In order to transport the PUR glue in the first glue outlet groove 15 to the second glue outlet groove 14, a first glue outlet groove 15 is opened in the middle of the bottom of the glue outlet block 9, and a second glue outlet groove 14 is opened in the middle of one side of the glue outlet block 9. One end of the first glue outlet groove 15 is opened in the middle of the bottom of the glue outlet block 9, and one end of the first glue outlet groove 15 is opened in the middle of the bottom of the glue outlet block 9 to prevent the PUR glue from flowing out from one end of the first glue outlet groove 15. The other end of the first glue outlet groove 15 is connected to the second glue outlet groove 14, so that the PUR glue can accurately flow into the second glue outlet groove 14 along the first glue outlet groove 15.

[0035] In order to prevent PUR glue from leaking out of the glue inlet hole 5, the edge of the glue inlet hole 5 is recessed on one side of the glue inlet block 1. The recessed setting of the glue inlet hole 5 is convenient for connection with the glue delivery pipeline and the interface is convenient for sealing. If it is directly connected on the surface of the glue outlet block 9, the sealing of the interface is troublesome and it is difficult to prevent PUR glue from leaking out.

[0036] Working principle: The steps for use are as follows:

[0037] The PUR glue enters the glue block 1 from the glue inlet hole 5. The glue inlet hole 5 and the glue outlet hole 6 are connected. The PUR glue passes through the glue outlet hole 6. Since the glue outlet hole 6 is connected to the first glue outlet groove 15, the other end of the first glue outlet groove 15 is connected to the second glue outlet groove 14. The PUR glue enters the first glue outlet groove 15 through the glue outlet hole 6, and then enters the second glue outlet groove 14 through the first glue outlet groove 15. The second glue outlet groove 14 contacts the joint of the back panel, and the second glue outlet groove 14 slides along the joint, and the PUR glue bonds the back panel together.

[0038] Therefore, this solution has a simple structure, low manufacturing and maintenance costs, an innovative back panel bonding process, stable performance, and is suitable for automated mass production. The second glue outlet groove 14 limits the path of the glue, so that the glue coating thickness and width are constant, the product is beautiful, the PUR glue has better toughness and weather resistance, and the product is more durable.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
