Description
Technical Field
[0001] This utility model relates to the field of edge banding and cleaning technology for edge banding machines, specifically a novel edge banding machine separator and cleaning agent spraying device. Background Technology
[0002] Edge banding cleaning technology is a crucial step in panel furniture manufacturing, directly impacting product appearance quality and production efficiency. Traditional manual cleaning methods suffer from low efficiency, poor results, and high costs, making them unsuitable for modern large-scale production. With the development of automation technology, the industry has begun exploring more efficient edge banding cleaning solutions, primarily categorized into three types: physical mechanical cleaning, chemical treatment, and intelligent control systems. Physical mechanical cleaning achieves efficient debris removal through rotating brushes and negative pressure suction; chemical treatment utilizes separating agents and cleaning agents to dissolve adhesive residues; and intelligent control systems achieve automated cleaning through sensors and pneumatic components. These edge banding cleaning technologies significantly improve cleaning efficiency and quality, propelling the industry towards fully automated production.
[0003] Currently, the main method used in edge banding machines for panel furniture production lines is a combination of a two-fluid nozzle and a solenoid valve based on the Venturi effect. After receiving the blowing signal, the solenoid valve delivers compressed air to the nozzle. When the compressed air passes through the constriction channel of the nozzle, the flow rate increases, forming a low-pressure zone according to Bernoulli's principle. The resulting negative pressure draws the liquid into the mixing chamber through the detergent tube. The high-speed airflow and the liquid undergo shearing action in the mixing chamber, breaking the droplets into atomized particles before spraying them out.
[0004] The aforementioned spraying combination method provides good atomization, uniform spraying, and timely start and stop. However, it suffers from poor flexibility; the position of the limit switch that triggers the spraying signal cannot be changed, and it remains fixed at the factory setting. Furthermore, the two-fluid nozzle requires both compressed air and cleaning agent, leading to frequent nozzle clogging and replacement. Replacement necessitates disassembling the fixing nut, cleaning agent tubing, and compressed air tubing, which is time-consuming and labor-intensive. Therefore, a new type of edge banding machine separator and cleaning agent spraying device is needed, which offers high flexibility, allows for easy repositioning, and facilitates time-saving and labor-saving nozzle replacement. Utility Model Content
[0005] The purpose of this invention is to provide a new type of spraying device for separating and cleaning agents in edge banding machines, so as to solve the problems of poor flexibility, time-consuming and laborious nozzle replacement, and reduced production efficiency of existing spraying devices.

[0022] like Figures 1 to 4 As shown in the figure, a preferred embodiment of the present invention provides a novel edge banding machine separator and cleaning agent spraying device, including a nozzle bracket, a limit switch 2, a nozzle assembly, and an electrical control box 4. The nozzle assembly includes two quick-connect nozzles 31 and a partition sleeve quick-connect straight-through 32 connected to each nozzle 31 by a plug-in connection. One end of the partition sleeve quick-connect straight-through 32 is connected to the conveying pipeline. The electrical control box 4 is provided with a self-priming pump 42 and a solenoid valve 41 and an energized time delay relay 43 connected to the self-priming pump 42. The solenoid valve 41 is connected to the conveying pipeline. The limit switch 2 is mounted on the nozzle bracket and electrically connected to the energized time delay relay 43 for starting and stopping the spraying device.
[0023] The nozzle support includes an upper nozzle support 11 and a lower nozzle support 12 arranged symmetrically with a vertical gap between them. Both the upper nozzle support 11 and the lower nozzle support 12 include an L-shaped support 13 and an N-shaped support 14. Two nozzles 31 are respectively disposed on the upper nozzle support 11 and the lower nozzle support 12. On the N-type bracket 14, the L-type bracket 13 is provided with a first long side surface 131 and a first short side surface 132. The first long side surface 131 is provided with an adjustment hole 133 for adjusting the position of the nozzle 31 up and down. The L-type bracket 13 is fixed to the edge banding machine through the adjustment hole 133. The first short side surface 132 is provided with an adjustment hole 234 for adjusting the position of the nozzle 31 back and forth. The L-type bracket 13 and the N-type bracket 14 are connected through the adjustment hole 234. The N-type bracket 14 is provided with a second long side surface 141, a second short side surface 142 located at the top and bottom of the second long side surface 141, and a third short side surface 143. The third short side surface 143 is provided with an adjustment hole 344. The partition sleeve quick-insertion straight passage 32 is provided on the adjustment hole 344 and can move left and right along the adjustment hole 344 so as to adjust the position of the nozzle 31 left and right.
[0024] In this embodiment, the first short side surface 132 is located at the top or top of the first long side surface 131, and the first short side surface 132 is perpendicular to the first long side surface 131; the second short side surface 142 and the third short side surface 143 are located at the top or top of the second long side surface 141, and both the second short side surface 142 and the third short side surface 143 are perpendicular to the second long side surface 141.
[0025] Specifically, the L-shaped bracket 13 is a bent L-shaped plate, including a plate body and a folded edge formed by bending from the top or bottom of the plate body. The first long side surface 131 is located on the plate body, and the first short side surface 132 is located on the folded edge. Two adjustment holes 133 and 134 are provided, both being elongated through holes. A screw 147 passes through the adjustment hole 133 to fix the L-shaped bracket 13 to the edge banding machine. Before the L-shaped bracket 13 is locked in place, the position of the nozzle 31 can be adjusted up and down by moving the L-shaped bracket 13 up and down along the adjustment hole 133.
[0026] Specifically, the N-type bracket 14 is a bent N-shaped plate, including a plate body and two folded edges formed by bending from the top and bottom of the plate body to one side. The second long side surface 141 is provided on the plate body, and the second short side surface 142 and the third short side surface 143 are correspondingly provided on the two folded edges. The second short side surface 142 has two through holes 145. The screw 147 passes through the adjustment hole 134 of the L-type bracket 13 and the through hole 145 of the N-type bracket 14 in sequence and is screwed to the nut, thereby connecting and fixing the N-type bracket 14 and the L-type bracket 13. Before the N-type bracket 14 and the L-type bracket 13 are fixed and locked, the position of the nozzle 31 can be adjusted back and forth by moving the N-type bracket 14 back and forth along the adjustment hole 134 of the L-type bracket 13.
[0027] Limit switch 2 starts and stops the spraying device by sending start and stop signals for the entire spraying device. Limit switch 2 is electrically connected to energized time delay relay 43 via signal line 21. Specifically, in this embodiment, limit switch 2 is mounted on N-type bracket 14 of lower nozzle bracket 12 by screws.
[0028] Preferably, the second long side surface 141 of the N-type bracket 14 is provided with two elongated clearance holes 146. The two clearance holes 146 are aligned with the two adjustment holes 133 of the L-type bracket 13. The clearance holes 146 are used to allow a screwdriver to pass through the clearance holes 146 to adjust the position of the L-type bracket 13 up and down without disassembling the N-type bracket 14.
[0029] Furthermore, the adjustment hole 3 144 of the N-type bracket 14 is an elongated through hole, and the quick-connect straight tube 32 of the partition sleeve passes through the adjustment hole 3 144. The outer peripheral surface of the quick-connect straight tube 32 of the partition sleeve is provided with threads, and a fixing nut 33 is screwed onto the quick-connect straight tube 32 of the partition sleeve. The fixing nut 33 is used to fix the adjusted quick-connect straight tube 32 of the partition sleeve on the adjustment hole 3 144 of the N-type bracket 14.
[0030] Specifically, nozzle 31, mounted on the upper nozzle bracket 11, is used to spray the upper surface of the material, while nozzle 31, mounted on the lower nozzle bracket 12, is used to spray the lower surface of the material. Nozzles 31 spray atomized cleaning agent, and are equipped with atomization adjustment nuts to adjust the atomization effect. The delivery pipeline is used to deliver the required liquid (cleaning agent / separator), including a main pipeline 34, two branch pipelines 35, and a Y-type tee 36 connecting the main pipeline 34 and the two branch pipelines 35. A quick-connect fitting 32 with a baffle clamp is correspondingly connected between the nozzle 31 and the branch pipelines 35. The Y-type tee 36 is used for liquid diversion; one end of the Y-type tee 36 is connected to the main pipeline 34, and the two ends of the Y-type tee 36 are connected to the two branch pipelines 35.
[0031] Specifically, the electrical control box 4 is divided into two chambers by a partition. One chamber contains a self-priming pump 42 and a solenoid valve 41, while the other chamber contains a power-on delay relay 43. The self-priming pump 42 is fixed to the base plate of the electrical control box 4 with screws and is used to provide power to the entire spraying device. The inlet of the self-priming pump 42 is connected to a tank containing the required liquid (cleaning agent / separating agent) through a liquid extraction pipe 421, so as to draw the required liquid from the tank and deliver it to the nozzle 31.
[0032] Solenoid valve 41 is fixed to the base plate of electrical control box 4 with screws. It is used to open and close the delivery pipeline in a timely manner to prevent dripping of nozzle 31 due to inertial operation after the self-priming pump 42 motor is powered off. The inlet of solenoid valve 41 is connected to the outlet of self-priming pump 42, and the outlet of solenoid valve 41 is connected to main pipeline 34. A time-delay relay 43 is fixed to the base plate of electrical control box 4 with screws and electrically connected to self-priming pump 42. It is used to adjust the delay spraying time of nozzle 31. Because there is a distance between limit switch 2 and nozzle 31, after limit switch 2 issues a stop signal, the board may not have passed nozzle 31, resulting in a small section of the board's rear end not being coated with cleaning agent / separating agent. The spraying time is extended by setting time-delay relay 43, which is connected to a 24V DC power supply via power line 44. Specifically, in this embodiment, self-priming pump 42 can be a DC electric self-priming diaphragm pump, and solenoid valve 41 is a single-unit double-way solenoid valve.
[0033] Reference Figure 5 The aforementioned spraying device is connected to a 24V DC power supply. SQ is a limit switch, KT is an energized time-delay relay, PR is a pressure relay, YV is a solenoid valve, and M is a self-priming pump DC motor. The normally open contact of the limit switch SQ and the normally closed contact of the energized time-delay relay KT are connected in parallel to form the first parallel branch. The self-priming pump DC motor M and the solenoid valve YV are connected in parallel to form the second parallel branch. The pressure relay PR is connected in series with the first and second parallel branches to form the first series branch. The normally closed contact of the limit switch SQ and the energized time-delay relay KT are connected in series to form the second series branch. The second series branch is connected in parallel with the first series branch, and both ends are connected to a 24V DC power supply.
[0034] The electrical control principle of the above-mentioned spraying device is as follows: After initial power-on, because the time-delayed disconnect contact of the power-on delay relay KT is in the closed state, the self-priming pump DC motor M and the solenoid valve YV immediately start running and opening, and the nozzle 31 performs pre-spraying. After the time-delayed contact of the power-on delay relay KT reaches its set time, the time-delayed disconnect contact of the power-on delay relay KT opens, the self-priming pump DC motor M stops running, the solenoid valve YV closes, and the nozzle 31 stops spraying. This is intended to fill the delivery pipeline with cleaning agent / separating agent, preparing for the formal spraying. When the board enters the edge banding machine, the limit switch SQ is triggered. The normally open contact of the limit switch SQ closes, immediately conducting the self-priming pump DC motor M and the solenoid valve YV to spray the cleaning agent / separating agent. At the same time, the normally closed contact of the limit switch SQ opens, resetting the power-on delay relay KT. When the board leaves the limit switch SQ, the normally open contact of the limit switch SQ changes from closed to open, and the normally closed contact changes from open to closed, conducting the power-on delay relay KT. At this point, because the energizing delay relay KT has deactivated after a delay, its normally closed contact remains closed, so the self-priming pump DC motor M and solenoid valve YV are still running and open. After the energizing delay relay KT has completed its delay, its normally closed contact opens, closing the solenoid valve YV and the self-priming pump DC motor M, thus completing the coating process for one sheet of material.
