Description

TECHNICAL FIELD

[0001] The application relates to a wood board tooth joint board glue port intelligent selection mechanism. BACKGROUND

[0002] The tooth joint board is formed by splicing a plurality of wood boards, and the upper and lower boards are not bonded and pressed by a clamp plate. Since a sawtooth-shaped interface is adopted between the vertical wood boards, the strength and appearance quality of the wood are improved, and the board is called a tooth joint board. The tooth joint board is used as a high-quality material for furniture, cabinets, wardrobes and the like. The tooth joint board often needs to be coated with glue during production. The existing tooth joint board coating operation generally adopts manual coating. The manual tooth joint board coating work is relatively fine, but the coating efficiency is low, and the degree of automation is low, so it is difficult to meet the coating and production work of large-scale tooth joint boards. Therefore, a roller type glue coating mechanism appears on the market. The roller is immersed in a glue tank, and the glue adhered to the roller is coated onto the board. However, in the roller coating, the coating area cannot be adjusted according to the width of the board, but the whole roller is immersed in glue, so that some glue will drip or flow onto the surface of the board during the coating process. Therefore, it is necessary to arrange a station to clean the glue, which brings inconvenience to the production efficiency and production cost, and further improvement is needed. SUMMARY

[0020] The glue cavity adjusting mechanism further comprises a lead screw seat 38 arranged outside the side baffle 35, a lead screw shaft 310 driven by a servo motor 39 is arranged on the lead screw seat 38, a lead screw nut 311 is screwed on the lead screw shaft 310, and the lead screw nut 311 is connected with the driving column 37.

[0021] The glue cavity adjusting mechanism further comprises a side pushing plate 312 arranged on the back of the glue sealing plate 31, a rear pushing plate 313 is arranged at the rear of the side pushing plate 312, and the rear pushing plate 313 is pressed on the back baffle 34; a rear pushing cylinder 314 is arranged between the rear pushing plate 313 and the side pushing plate 312, and the rear pushing cylinder 314 drives the glue sealing plate 31 to move towards the glue applying rack 21; an inclined pushing cylinder 315 is further arranged on the side pushing plate 312, an inclined pushing block 316 is arranged on the rod of the piston 53 of the inclined pushing cylinder 315, the inclined pushing block 316 is inserted between the glue sealing plate 31 and the side baffle 35, and the inclined pushing block 316 drives the glue sealing plate 31 to move towards the main frame 1.

[0022] The surface of the glue cavity 32 is covered with a sealing ring 4.

[0024] Working principle: the case of the glue application equipment including glue application mechanism 2 including glue application rack 21, glue application rack 21 is provided with a plurality of teeth 22, tooth 22 tooth groove both sides are provided with glue groove 23, glue groove 23 is connected with glue port selection mechanism 3 through glue channel 24;When the cut tooth board passes through the glue application rack 21, the glue in the glue groove 23 is evenly applied on the tooth of the board.

[0025] Further; because the width of the production board is inconsistent, the tooth number of the board is also different. Therefore, generally, the width of the glue application rack is designed to be rich, and if all the teeth in the glue application mechanism are supplied with glue, it will cause the waste of glue in the tooth which is not in contact with the board, and the glue will also drip to the surface of the board, which needs to be cleaned later. Therefore, the case is provided with glue port selection mechanism 3. It includes glue sealing plate 31 covering the surface of glue channel 24, glue sealing plate 31 is provided with glue cavity 32 corresponding to one side of glue channel 24, the bottom of glue channel 24 is provided with glue cavity block 33, glue cavity block 33 and glue channel 24 are covered in glue cavity 32;The glue sealing plate 31 is also connected with the glue cavity adjusting mechanism. In the glue cavity adjusting mechanism, the board width detection device can be set at the feeding end of the board, and the board thickness data is transmitted to the control system. The control system drives the screw rod to rotate through the servo motor, and the screw rod and the screw nut cooperate to convert the rotary motion into linear motion, thereby driving the glue sealing plate 31 to slide up and down. The distance between the glue cavity block 33 and the top of the glue cavity 32 is changed to adjust the number of glue channels 24. The height of the glue tooth is consistent with the required height of the board, and the glue tooth which does not need to be glued does not glue, so that the glue supply is more accurate, and the waste of glue is avoided, and the trouble of cleaning the board adhered by excess glue later is avoided.

[0026] Further; because the number of glue supply of the glue tooth is a variable value, in order to ensure the rapid and timely supply of glue, a plurality of glue supply holes 43 are opened on the main glue channel 42, the glue supply holes 43 are communicated with the glue cavity 32, and the plurality of glue supply holes 43 are vertically parallel with the glue channel 24. Glue supply valve 44 is arranged on glue supply hole 43, which controls the opening or closing of glue supply hole 43;The main glue channel 42 is also connected with the glue pump, and the glue pump supplies glue into the main glue channel 42;When the height of the main glue channel is lower than the height of the glue supply hole, the glue supply valve on the glue supply hole is closed. By accurately controlling the opening and closing of the glue supply hole, the accurate cooperation between the main glue channel and the glue cavity is realized.

[0027] Further, since the glue sealing plate needs to be in a sealed state with the glue supply channel 24 during glue supply, the glue cavity adjusting mechanism in the case also includes a side push plate 312 arranged on the back of the glue sealing plate 31, a rear push plate 313 arranged at the back of the side push plate 312, the rear push plate 313 pressing on the rear baffle 34, a rear push cylinder 314 arranged between the rear push plate 313 and the side push plate 312, the rear push cylinder 314 pushing the glue sealing plate 31 to move towards the glue applying rack 21, and maintaining the front and back direction sealing between the glue sealing plate and the glue applying rack.

The rear push cylinder and the inclined push cylinder are retracted when the glue sealing plate is adjusted, so that the glue sealing plate can move relative to the glue applying rack. When the height is adjusted to the right position, the rear push cylinder and the inclined push cylinder work to lock the relative position between them. After the glue sealing plate and the glue applying rack are sealed, the glue with pressure can be supplied into the glue cavity, so that the glue can uniformly enter the glue cavity of the glue applying rack from each glue supply channel. When adjustment is needed again, the rear push cylinder and the inclined push cylinder are reset, and the servo motor drives the glue sealing plate to move again. The whole operation process is automatically controlled by the control system, and manual adjustment of mechanical parts is not needed, which can greatly improve the equipment conversion efficiency, and can be widely used.
