Description

Technical Field

[0001] The utility model relates to the field of glue binding machines, in particular to a switching device for glue and cleaning liquid used in glue spraying glue binding machines. Background Art

[0002] A small linear wireless glue binder is a device that applies hot melt glue on the spine side of the book core to glue and staple books. The glue binders generally use EVA hot melt glue and PUR hot melt glue. EVA hot melt glue is an ordinary hot melt glue with low cost. The glue after heating and melting will be completely solidified after 24 hours and can be heated and melted again; EVA hot melt glue generally uses an open glue box, and the books after gluing cannot be opened 180°. PUR hot melt glue is more expensive, but has excellent bonding strength and excellent heat resistance, chemical resistance, corrosion resistance, and aging resistance. The glue layer of glued books is thin and flexible, and the bound books can be flattened 180°. This glue has been rapidly developed and applied in recent years. In particular, if the machine is not cleaned in time after use, the glue path of the glue binder is prone to blockage, which will directly affect the normal operation of the machine.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-5 A switching device for glue and cleaning liquid used in a glue spraying machine includes a base 1, a glue hole 101 connected to the bottom of a glue box 2, a cleaning liquid hole 102 connected to the bottom of a cleaning liquid box 3, a switching component 4 arranged in the base 1 and connected to a glue spraying channel 6, and a driving component 5 connected to the switching component 4. The driving component 5 drives the switching component 4 to rotate, so that the switching component 4 controls the glue hole 101 to be connected to the glue spraying channel 6 or controls the cleaning liquid hole 102 to be connected to the glue spraying channel 6, and the glue spraying channel 6 is connected to a glue spraying device for spraying PUR glue.

[0019] The utility model realizes the rapid switching of the two modes of connection between the glue spray channel 6 and the glue hole 101 and the connection between the glue spray channel 6 and the cleaning liquid hole 102 by setting the switching component 4 and the driving component 5, so that the cleaning liquid in the cleaning liquid box 3 can quickly enter the glue spray channel 6 for cleaning, avoiding blockage of the glue path.

[0020] Further, the switching assembly 4 includes a tube body 401 disposed in the base 1, a first through hole 402 and a second through hole 403 passing through the tube body 401, and blocking bolts 404 disposed at both ends of the tube body 401. Preferably, the length of the blocking bolt 404 is 1 / 3-2 / 5 of the length of the tube body 401. By providing the blocking bolt 404, the space inside the tube body 401 can be reduced to avoid excessive glue from sticking in the tube body 401. In the present embodiment, when the first through hole 402 is connected to the glue hole 101, the second through hole 403 is connected to the glue spray channel 6; when the second through hole 403 is connected to the cleaning liquid hole 102, the first through hole 402 is connected to the glue spray channel 6.

[0021] Furthermore, the axial center lines of the first through hole 402 and the second through hole 403 are perpendicular to each other. This arrangement allows the tube body 401 to be quickly switched between the two modes of connection between the glue spray channel 6 and the glue hole 101 and the connection between the glue spray channel 6 and the cleaning liquid hole 102 by simply rotating 90°.

[0022] In more detail, in order to prevent cleaning liquid and glue from entering the gap between the tube body 401 and the base 1 , an annular groove 405 is provided on the outer wall of the tube body 401 , and a sealing ring 406 is embedded in the annular groove 405 .

[0023] In general, the driving assembly 5 includes a rotating plate 501 disposed at one end of the tube body 401, a propulsion plate 502 rotatably connected to the rotating plate 501, a cylinder 503 for pushing the propulsion plate 502 to move, a mounting block 504 connected to the cylinder 503, a fixing frame 505 disposed on one side of the base 1, and a rotating shaft 506 disposed on the fixing frame 505 and rotatably connected to the mounting block 504. The cylinder 503 drives the propulsion plate 502 to move and drives the rotating plate 501 to rotate, so that the tube body 401 rotates in the base 1, thereby realizing rapid switching between the two modes of connection between the glue spray channel 6 and the glue hole 101 and the connection between the glue spray channel 6 and the cleaning liquid hole 102.
