[0050] Please refer to Figures 1 - 15 As shown, the present invention provides a synchronous rolling process for the production of multi-layer wood veneers for wooden doors, including the following steps:

[0051] S1. First, stack a number of wood veneers on a number of layered plates 101 in the veneer rack 100 in sequence;

[0052] S2. Simultaneously start the forward and reverse motor 220 to drive the glue sealing roller 210 to discharge the glue liquid in the glue cylinder 200 onto the uppermost glue fixing roller 230, start the distance adjusting motor 260 to drive a number of moving glue rollers 240 to contact the glue fixing roller 230 above each of them, and start the roller driving motor 270 to drive a number of glue fixing rollers 230 to drive a number of moving glue rollers 240 to rotate and apply glue;

[0053] S3. After the glue fixing roller 230 and the moving glue roller 240 at the lowermost part of the glue cylinder 200 are both applied with glue, then start the distance adjusting motor 260 to drive a number of moving glue rollers 240 to separate from the glue fixing roller 230 to leave a gap;

[0054] S4. Then start the main motor 130 to drive a number of dialing rollers 120 above the right end of a number of layered plates 101 to rotate synchronously, and then dial the uppermost wood veneer through the gap in S3 to be double-sidedly applied with glue;

[0055] S5. As the glue fixing roller 230 and the moving glue roller 240 clamp the wood veneer and move to the right until a number of wood veneers fall onto a number of pairs of supporting veneer rollers 320 between the supporting veneer racks 300;

[0056] S6. Then, place a wooden board on the bottom of the leather support frame 300, and then start the leather unloading motor 334 to drive several pairs of leather support rollers 320 between the leather support frames 300 to turn down successively from the upper layer to the lower layer and hide inside the leather support frame 300. Then, several pieces of wood veneer fall successively from top to bottom and are stacked on the wooden board;

[0057] S7. Then, place another wooden board on the wood veneer so that the upper and lower surfaces of several pieces of wood veneer are covered with wooden boards. Then, start the transmission motor 354 to drive the roller 351 to move above the bottom of the leather support frame 300 and roll the wooden board directly above to press several pieces of wood veneer tightly, and then stick them together to form a whole, forming a wooden door.

[0058] In this embodiment, the structure of the above process includes a leather placing frame 100 and several layered plates 101 arranged at equal intervals inside the leather placing frame 100. The corners of the layered plates 101 are welded to the inner side of the vertical section of the leather placing frame 100. At the right end inside the leather placing frame 100 and above each layered plate 101, there is a dialing roller 120. At the rear side of the leather placing frame 100, there is a driving motor 130 for driving several dialing rollers 120 to rotate synchronously. The rear end of the dialing roller 120 is sleeved with a belt pulley, and the output shaft end of the driving motor 130 is sleeved with a belt pulley. The outer sides of several belt pulleys are sleeved with a belt to drive several dialing rollers 120 to rotate and dial the wood veneer out of the leather placing frame 100;

[0059] Further, an outlet 104 is provided on the right side surface of the leather placing frame 100 for moving out the wood veneer. A bayonet 103 is provided on the front side of the leather placing frame 100 and above each layered plate 101. If the bayonet 103 is not provided at the rear side of the leather placing frame 100, the left and right ends of the wood veneer are inserted into the bayonet 103, and then they can be limited at the rear side of the leather placing frame 100 and stacked neatly on the layered plate 101;

[0060] In the middle of the top surface of the layered plate 101, there is a clamping hole 1011, and a top plate 102 is clamped inside the clamping hole 1011. Below the layered plate 101, there is a pressure roller 110 for supporting the top plate 102. The top plate 102 is used to support several pieces of wood veneer to rise, and the pressure roller 110 is used to press the wood veneer to limit the height. The pressure rollers 110 of the same layer are at the same height as the bottom surface of the dialing roller.

[0061] Specifically, several telescopic tube groups 1021 are connected to the bottom surface of the top plate 102. A spring 1022 is sleeved outside the telescopic tube groups 1021. The telescopic tube groups 1021 are composed of circular tubes sleeved inside and outside, and the bottom end of the inner circular tube is welded to a ring sleeved with the pressure roller 110. The top of the outer tube of the telescopic tube groups 1021 is welded to the bottom surface of the top plate 102. The front and rear ends of the pressure roller 110 are sleeved with straight rods, and the top ends of the straight rods are welded to the top surface of the layered plate 101 to position the pressure roller 110. The elastic force of the spring 1022 is used to elastically move the top plate 102 to support several pieces of wood veneer to rise, so that the wood veneer can contact the dialing roller 120 and be rolled out of the leather placing frame 100.

[0062] It should be noted that an air pump motor 140 is installed at the top of the leather placing rack 100. An air pipe 150 connected to the air pump motor 140 is inserted into the four corners of the leather placing rack 100. A straight pipe is inserted in the middle of the top of the air pipe 150, and the straight pipe is inserted into the air outlet pipe of the air pump motor 140.

[0063] A number of air outlet pieces 151 are inserted on the side of the air pipe 150 facing the laminating plate 101. The outlet of the air outlet piece 151 is flat and points to the bottom gap of the veneer on the topmost layer. A stop bar 1012 is inserted at the right corner of the top surface of the laminating plate 101. The top surface of the stop bar 1012 is flush with the bottom surface of the air outlet piece 151. The stop bar 1012 is used to intercept all the veneers on the laminating plate 101 except the topmost layer. When the roller 120 rotates to move the topmost veneer, the air pump motor 140 pumps air and sprays it into the gap between the topmost veneer and the veneer below it through the air outlet piece 151, reducing the friction of the veneer movement and enabling it to be smoothly moved out of the leather placing rack 100 by the roller 120.

[0064] In addition, a glue cylinder 200 is arranged outside the right end of the leather placing rack 100. A through pipe is inserted at the top front end of the glue cylinder 200 for injecting glue. The central axis of the glue cylinder 200 is horizontally arranged, and a sealing glue roller 210 is embedded at the bottom opening thereof. Both ends of the sealing glue roller 210 are embedded in the front and rear ends of the glue cylinder 200. A positive and negative rotation motor 220 coaxially connected to the sealing glue roller 210 is installed at one end of the glue cylinder 200. A glue discharge groove 211 is arranged on the outer side of the sealing glue roller 210 deviating from its central axis.

[0065] When the glue discharge groove 211 turns to the vertical direction, the glue in the glue cylinder 200 can be discharged, and it falls onto the topmost fixed glue roller 230 and gradually falls onto the surfaces of the remaining fixed glue rollers 230 and the moving glue roller 240 as the fixed glue roller 230 rotates. When the glue discharge groove 211 turns to the horizontal direction, the large-diameter sides of the sealing glue roller 210 block the bottom through hole of the glue cylinder 200.

[0066] Furthermore, support pipes 201 are welded to the bottom of both ends of the glue cylinder 200. A number of pairs of fixed glue rollers 230 and moving glue rollers 240 are arranged between the two support pipes 201. Distance adjustment motors 260 for driving the up and down movement of a number of moving glue rollers 240 are installed at the outer bottom of both support pipes 201. A driving roller motor 270 for driving the synchronous rotation of a number of fixed glue rollers 230 is installed at the outer top of one support pipe 201. A belt pulley is sleeved on the rear end of the fixed glue roller 230, and a belt pulley is sleeved on the output shaft end of the driving roller motor 270. A belt is sleeved outside a number of belt pulleys to drive a number of fixed glue rollers 230 to rotate and move the veneer inserted between the fixed glue rollers 230 and the moving glue rollers 240 out of the glue cylinder 200.

[0067] Specifically, a number of jacks 202 and a number of chutes 203 are equidistantly arranged on the side of the support tube 201. The chutes 203 are in the structure of upper and lower rounded rectangular holes, and each chute 203 is correspondingly located below each jack 202. The fixed rubber roller 230 is inserted into the jack 202, and the moving rubber roller 240 is inserted into the chute 203, so that the moving rubber roller 240 can move up and down to adjust the distance from the fixed rubber roller 230, and thus clamp the veneer and roll it out;

[0068] The top end of the output shaft of the distance-adjusting motor 260 is coaxially connected with a distance-adjusting lead screw 250. Both ends of the moving rubber roller 240 are sleeved with round caps, and a thread sleeve 251 threaded with the distance-adjusting lead screw 250 is welded to the outside of the round cap. The thread sleeve 251 is vertically arranged with respect to the axial direction of the round cap. The distance-adjusting motor 260 is used to drive the distance-adjusting lead screw 250 to drive the thread sleeve 251 to move along the axial direction of the distance-adjusting lead screw 250, and the moving rubber roller 240 is supported by the round cap and moves up or down synchronously.

[0069] In addition, a veneer support 300 is arranged on the right side of the rubber cylinder 200. The veneer support 300 is composed of a pair of frames arranged at intervals front and back and a platform at its bottom; a number of veneer support rods 310 are arranged between the inner sides of the veneer support 300, that is, the veneer support rods 310 are located within the frames, and the veneer support rods 310 are in an inclined shape with the right end tilted downward. A number of veneer support rollers 320 are rotatably connected at equal intervals on the inner side of each veneer support rod 310, so that the veneer moved out from below the rubber cylinder 200 can slide down onto the veneer support rollers 320 and be suspended inside the veneer support 300 for stacking below.

[0070] The veneer support rollers 320 are made of Teflon material and are in a cylindrical shape. Teflon is a high molecular polymer obtained by polymerizing tetrafluoroethylene as a monomer. Its surface is smooth and has anti-adhesion properties. The property of not adhering to any substance is used to prevent the veneer coated with an adhesive layer from slipping.

[0071] Specifically, a veneer unloading mechanism 330 is arranged at the right end of the veneer support 300, which is used to drive a number of veneer support rollers 320 to turn downward to the outside of the veneer support 300, so that the supported veneer falls and is stacked on the platform at the bottom of the veneer support 300 for rolling and supporting the wooden door;

[0072] The veneer unloading mechanism 330 includes a transmission shaft 331 coaxially inserted into the veneer support rod 310 and a veneer unloading motor 334 for driving the transmission shaft 331 to rotate; sprockets 332 are sleeved on the right ends of a number of transmission shafts 331, and the outer diameters of a number of sprockets 332 gradually increase from top to bottom. A chain 333 is meshed with the outside of a number of sprockets 332, and the veneer unloading motor 334 is coaxially connected with the sprocket 332 meshed with the inside of the bottom of the chain 333, so that a number of veneer support rollers 320 located above always turn downward faster than a number of veneer support rollers 320 below them. Thus, several layers of veneer are stacked in sequence with the veneer on the upper layer falling first, ensuring that the veneer does not displace during the short-distance fall.

[0073] Further, a number of sleeves 311 are sleeved on the top leather rod 310 at equal intervals. A collar 321 sleeved with the sleeve 311 is welded to the outer end of the top leather roller 320. The collar 321 is welded to the central axis of the top leather roller 320, and their axial directions are perpendicular to each other. An arc groove 312 is formed on the inner side surface of the sleeve 311. The central angle of the arc groove 312 is greater than 180 degrees and less than 260 degrees. A pin is inserted into the top surface of the collar 321 and the pin is inserted into the transmission shaft 331. The rotation of the transmission shaft 331 drives a number of top leather rollers 320 to turn up and down.

[0074] Symmetrically arranged at the bottom of the front side of the top leather frame 300 are inlets and outlets 301 for placing wooden boards as the bottom layer. Above the inlets and outlets 301 are spaced-apart board placement openings 302 for placing another wooden board to cover and bond to a number of falling and stacked veneers. After the board placement opening 302 allows the wooden board to be suspended above the veneer and then fall as a whole to cover it.

[0075] It should be noted that a rolling mechanism 350 is provided at the bottom of the right side of the top leather frame 300. The rolling mechanism 350 includes a roller 351 and a driving motor 354 for driving it to move onto the bottom of the top leather frame 300.

[0076] The axial direction of the roller 351 is the same as the front-back direction of the top leather frame 300. Rings are sleeved on the front and rear ends of the roller 351, and a support rod 352 is welded to the horizontally radial side of the ring. The length of the support rod 352 is greater than the left-right direction length of the top leather frame 300. The outer end of the support rod 352 is bent downward and welded with a transmission sleeve 3521. A thread is provided inside the transmission sleeve 3521. The output shaft end of the driving motor 354 is coaxially connected with a transmission lead screw 353 coaxially connected with the transmission sleeve 3521. A support frame 355 is sleeved at one end of the support rod 352 close to the roller 351 for supporting and restricting the roller 351 to stably press on the top surfaces of a number of veneers and wooden boards stacked at the bottom of the top leather frame 300 to form a wooden door.

[0077] It should be noted that the above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those familiar with this technology to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
