Description

Technical Field

[0001] The present application relates to the technical field of stitching machines, and in particular to a veneer stitching device. Background Art

[0002] The veneer stitching machine is a device specially used for veneer splicing. It can improve the efficiency and quality of veneer splicing and is widely used in furniture manufacturing, musical instrument making and other fields. The main function of the veneer stitching machine is to splice multiple veneers into wide veneers, which is suitable for the use of veneer core boards such as plywood, furniture, and musical instruments.

[0003] The current veneer splicing equipment includes a machine body, and a hot melt extrusion splicing module is arranged on the top of the machine body. The hot melt extrusion splicing module mainly uses hot melt glue lines to splice two pieces of veneer together, and forms glue line marks on the surface through hot pressing treatment, so as to achieve a firm splicing of the veneer. At the same time, one end of the hot melt extrusion splicing module is the feed end, and the other end is the discharge end. When two pieces of veneer need to be spliced, the two pieces of veneer are first placed on the side of the machine body close to the feed end. After the ends of the two pieces of veneer close to each other are attached to each other, the two pieces of veneer are manually fed into the feed end at the same time. Finally, the spliced ​​veneer is output from the discharge end to complete the splicing of the veneer.

[0004] However, due to the high moisture content in the air and the hygroscopicity of the veneer, the edges of the veneer are prone to warping after absorbing moisture. Therefore, when the veneer is fed into the feed end, it is easy for the veneer to be unable to be spliced ​​due to the warping of the edges. In addition, when the veneer is pushed to the feed end by hand, the hot melt extrusion splicing module is easy to cause injury to the hands. Summary of the invention

[0005] In order to improve the stability of veneer splicing, the present application provides a veneer splicing device.

[0008] By adopting the above technical solution, when it is necessary to splice the veneer, first place the two pieces of veneer on the unloading rack respectively, and the two pieces of veneer are respectively located on both sides of the first partition bar, and then the two pieces of veneer are lifted up at the same time by the lifting mechanism, at this time the baffle squeezes the ends of the two pieces of veneer that are close to each other, and at the same time the driving component drives the pushing rack to move, and the pushing rack simultaneously pushes the two pieces of veneer towards the direction close to the feeding end, after the two pieces of veneer are pushed onto the conveyor belt, the conveyor belt simultaneously drives the two pieces of veneer into the hot-melt extrusion splicing module, and the two pieces of veneer are simultaneously pushed to the feeding end by the pushing rack, which is conducive to avoiding the situation where the operator's hand is sent into the hot-melt extrusion splicing module due to erroneous operation, and at the same time in the process of pushing the veneer, the baffle squeezes the ends of the two pieces of veneer that are close to each other, to avoid bending of the ends of the two pieces of veneer that are close to each other and making it impossible to splice, thereby helping to improve the stability of the veneer splicing.

[0009] Optionally, the driving assembly includes a motor and a screw rod, a support platform is provided on one side of the material discharge rack, a slide groove is provided on the top surface of the support platform, the screw rod is rotatably arranged in the slide groove, the motor is arranged on one side of the support platform, one end of the screw rod is connected to the driving shaft of the motor, an adjustment block is slidably arranged in the slide groove, the screw rod thread passes through the adjustment block, and the pushing rack is arranged on the top surface of the adjustment block.

[0010] By adopting the above technical solution, when the motor is started, the output shaft of the motor drives the screw to rotate, the screw drives the adjusting block to slide in the slide groove, and the adjusting block drives the pushing rack to move. At this time, the pushing rack pushes the veneer onto the conveyor belt. The push rack is finally driven to move by the screw, which is conducive to controlling the moving speed of the pushing rack and avoiding the pushing rack from damaging the veneer due to excessively fast moving speed.

[0012] By adopting the above technical solution, the lifting plate is driven to rise through the transmission component, and the lifting plate drives the two veneers to rise at the same time, and the ends of the two veneers that are close to each other are squeezed in the baffle, thereby preventing the ends of the two veneers that are close to each other from folding, and when the lifting plate is raised, the pushing rack is pushed in the direction close to the lifting plate, and the pushing rack is connected with the lifting plate through the pushing groove, thereby improving the stability of pushing the veneer.

[0014] By adopting the above technical solution, when the adjusting block moves horizontally, the adjusting block drives the second connecting rod to move horizontally, the second connecting rod drives the first connecting rod to swing, and the first connecting rod drives the lifting plate to rise and fall. Through the horizontal movement of the adjusting block, when the pushing rack moves horizontally, the lifting plate lifts the veneer at the same time, so that the veneer can be stably pushed onto the conveyor belt, thereby improving the processing efficiency of the veneer.

[0016] By adopting the above technical scheme, when the motor speed and starting time are constant, the stroke of the adjustment block is constant. At this time, the distance between the pusher rack and the lifting plate determines the stroke of the veneer being pushed. When the veneer is long, the pusher rack can be driven away from the lifting plate, and then the pusher rack is fixed at the current position through the fixing component. Otherwise, the pusher rack is fixed close to the lifting plate through the fixing component, which is beneficial to improve the practicability of the pusher rack.

At this time, the insertion rod is disengaged from one of the slots and can drive the push rack to slide and adjust on the top surface of the adjustment block. When the insertion rod is released, the spring releases the elastic force and drives the insertion rod to be inserted into another slot. At this time, the push rack is fixed to the top surface of the adjustment block, which is conducive to improving the convenience of changing the pushing stroke of the push rack.

[0019] Optionally, extension plates are slidably provided on both sides of the lifting plate, and a fixing rod is fixedly provided on one side of the extension plate facing the lifting plate.

[0021] Optionally, the fixing member is a bolt, a plurality of thread grooves are formed on the top surface of the fixing rod, the bolt passes through the top surface of the lifting plate, and the bolt is threadably connected to the plurality of thread grooves respectively.

At this time, the baffle squeezes the ends of the two pieces of veneer that are close to each other, and at the same time, the driving component drives the pushing rack to move, and the pushing rack simultaneously pushes the two pieces of veneer toward the direction close to the feeding end. After the two pieces of veneer are pushed onto the conveyor belt, the conveyor belt drives the two pieces of veneer into the hot-melt extrusion splicing module at the same time, and the two pieces of veneer are pushed to the feeding end at the same time by the pushing rack, which is conducive to avoiding the situation where the operator's hands are sent into the hot-melt extrusion splicing module due to erroneous operation. At the same time, in the process of pushing the veneer, the baffle squeezes the ends of the two pieces of veneer that are close to each other, so as to avoid bending of the ends of the two pieces of veneer that are close to each other and making it impossible to splice, thereby helping to improve the stability of the veneer splicing.

Among them, one end of the hot melt extrusion splicing module 2 is a feeding end 3, and the other end is a discharging end 4. A first partition bar 5 is fixedly installed on the top surface of the machine 1, and two pieces of veneer are respectively located on both sides of the first partition bar 5, and the first partition bar 5 is located on the feeding end 3 side of the hot melt extrusion splicing module 2. A baffle 6 is fixedly connected to the top surface of the first partition bar 5, and the baffle 6 is used to block and press the ends of the two pieces of veneer that are close to each other to prevent the ends of the two pieces of veneer that are close to each other from folding. A conveyor belt 7 is fixedly installed on the top surface of the machine 1, and the conveyor belt 7 is used to transport the veneer to the feeding end 3 of the hot melt extrusion splicing module 2. There are two conveyor belts 7, and the two conveyor belts 7 are symmetrically arranged with the first partition bar 5. The machine 1 is fixedly provided with a material unloading rack 8 at the side of the feeding end 3, the material unloading rack 8 is lower than the top surface of the machine 1, and one end of the baffle 6 extends above the material unloading rack 8. A material pusher rack 9 is installed at the end of the material unloading rack 8 away from the machine 1, and the material unloading rack 8 is provided with a driving assembly for driving the material pusher rack 9 to move, and the material unloading rack 8 is provided with a lifting mechanism for simultaneously driving two pieces of veneer to rise and fall.

[0037] In this field, the hot melt extrusion splicing module 2 mainly uses hot melt glue lines to splice two pieces of veneer together, and forms glue line marks on the surface through hot pressing treatment, so as to achieve firm splicing of the veneer. When it is necessary to splice two pieces of veneer, first place the two pieces of veneer on the material discharging rack 8, and set the two pieces of veneer symmetrically with the first partition bar 5. Then the two pieces of veneer are lifted up at the same time by the lifting mechanism, and at this time the baffle 6 blocks and presses the end of the two pieces of veneer that is close to each other. While the two pieces of veneer are lifted up, the push rack 9 is driven to move by the driving assembly, and at this time the push rack 9 pushes the two pieces of veneer in the direction close to the feed end 3. Under the blocking and pressing action of the baffle 6, the two pieces of veneer are pushed into the feed end 3 along the first partition bar 5, and finally the two pieces of veneer are hot-melt spliced ​​by the hot melt extrusion splicing module 2, and the spliced ​​veneer is sent out from the discharge end 4 to complete the splicing.

[0038] For details, see Figure 3 The drive assembly includes a motor 10 and a screw 11. A support 12 is fixedly installed on the side of the unloading rack 8 away from the machine 1. A slide groove 13 is provided on the top surface of the support 12, and an adjustment block 14 is slidably installed in the slide groove 13. The motor 10 is fixedly installed on the side of the support 12 away from the machine 1, and the screw 11 is rotatably installed in the slide groove 13. The screw 11 is threadedly penetrated through the adjustment block 14, and one end of the screw 11 penetrates the support 12 and is coaxially fixedly connected with the driving shaft of the motor 10. The pusher rack 9 is installed on the top surface of the adjustment block 14.

[0039] When the motor 10 is driven, the driving shaft of the motor 10 drives the screw rod 11 to rotate, the screw rod 11 drives the adjustment block 14 to move toward the machine 1, and the adjustment block 14 drives the pusher rack 9 to move toward the machine 1. At this time, the pusher rack 9 pushes the veneer onto the conveyor belt 7. In addition, the method of driving the pusher rack 9 to move by the screw rod 11 is conducive to controlling the pushing speed of the pusher rack 9, and avoiding the pusher rack 9 from pushing too fast to cause damage to the veneer.

[0040] For details, see Figure 3 The lifting mechanism includes a lifting plate 15. The lifting plate 15 is located on the top surface of the material discharging rack 8. The end corners of the lifting plate 15 are fixedly connected to the guide rods 16. The top surface of the material discharging rack 8 is provided with a guide groove 17 at a position corresponding to the guide rod 16. The guide rod 16 is slidably connected to the guide groove 17. The top surface of the lifting plate 15 is fixedly connected to a second partition bar 18, and the second partition bar 18 is arranged opposite to the first partition bar 5. A push groove 19 is provided at one end of the lifting plate 15 away from the machine 1, and the material discharging rack 9 is plugged into the push groove 19.

[0041] See also Figure 3 In order to facilitate the lifting plate 15 to lift the veneer when the pusher 9 pushes the veneer, and to block and press the ends of the two veneers close to each other through the baffle 6, the unloading rack 8 is equipped with a transmission assembly, which includes a first connecting rod 20 and a second connecting rod 21. The first connecting rod 20 and the second connecting rod 21 are both installed in the unloading rack 8. One end of the first connecting rod 20 is hinged to the bottom surface of the lifting plate 15, and the other end of the first connecting rod 20 is a free end. One end of the second connecting rod 21 is hinged to the free end of the first connecting rod 20, and the other end of the second connecting rod 21 passes through the unloading rack 8 and the support platform 12 in sequence, and is fixedly connected to the adjustment block 14.

[0042] When the adjusting block 14 moves toward the direction close to the machine 1, the adjusting block 14 drives the second connecting rod 21 to move toward the direction close to the machine 1, and the second connecting rod 21 drives the first connecting rod 20. Under the guidance of the guide rod 16 and the guide groove 17, the lifting plate 15 drives the two veneers to rise. When the lifting plate 15 is lifted to be flush with the top surface of the machine 1, the adjusting block 14 drives the pushing rack 9 to move toward the direction close to the machine 1, and the pushing rack 9 then pushes the veneer onto the conveyor belt 7.

[0043] See also Figure 4 In order to facilitate the adjustment of the pushing stroke of the pushing rack 9, the pushing rack 9 includes a pushing rod 22 and a connecting rod 23. One end of the connecting rod 23 is fixedly connected to a U-shaped frame 24. There are two pushing rods 22, which are vertically arranged and respectively plugged into the pushing groove 19. The bottom end of the connecting rod 23 is slidably mounted on the top surface of the adjustment block 14.

[0044] See also Figure 3 and Figure 5In order to facilitate the fixing of the connecting rod 23, the adjusting block 14 is installed with a fixing assembly, and the fixing assembly includes an insert rod 25. The side wall of the connecting rod 23 is fixedly connected with a connecting block 26, and the number of the connecting blocks 26 is set to two. The insert rod 25 is slidably installed between the two connecting blocks 26, and both ends of the insert rod 25 penetrate and extend outside the connecting block 26. The top surface of the adjusting block 14 is provided with a slot 27, and the number of the slots 27 is set to be multiple, and the multiple slots 27 are respectively distributed at intervals along the length direction of the adjusting block 14. The bottom ends of the insert rod 25 are respectively plugged into the multiple slots 27. The side wall fixing ring of the insert rod 25 is provided with a stop block 28, and the insert rod 25 is sleeved with a spring 29, and one end of the spring 29 is fixedly connected to the stop block 28, and the other end of the spring 29 is fixedly connected to the inner wall of one of the connecting blocks 26.

[0045] In this embodiment, the rotation speed and rotation time of the motor 10 are constant, so the movement stroke of the adjustment block 14 is fixed. When it is necessary to increase the pushing stroke of the push rod 22 to push the veneer of shorter length, the insertion rod 25 is pulled upward, and the insertion rod 25 squeezes the spring 29 through the stop block 28, and the insertion rod 25 is disengaged from the slot 27. Then the connecting rod 23 is driven to move in the direction close to the machine 1. Then the insertion rod 25 is released, the spring 29 releases the elastic force, and drives the insertion rod 25 to move downward through the stop block 28, and the insertion rod 25 is inserted into another slot 27, and the connecting rod 23 is fixed to the top surface of the adjustment block 14.

[0046] See also Figure 6 In order to facilitate the placement of wider veneers on the lifting plate 15, extension plates 30 are slidably mounted on both sides of the lifting plate 15. A fixing rod 31 is fixedly connected to the extension plate 30 facing the lifting plate 15, and fixing grooves 32 are respectively opened at the positions corresponding to the fixing rods 31 on both sides of the lifting plate 15, and the fixing rods 31 are plugged into the fixing grooves 32.

[0047] In order to facilitate fixing the extension plate 30 to multiple extension lengths, the lifting plate 15 is installed with a fixing member, which is a bolt 33. The top surface of the fixing rod 31 is provided with a thread groove 34, and the number of the thread grooves 34 is provided in plurality, and the plurality of thread grooves 34 are respectively distributed at intervals along the length direction of the fixing rod 31. One end of the bolt 33 passes through the top surface of the lifting plate 15, and one end of the bolt 33 is respectively threadedly connected with the thread groove 34.

[0048] When it is necessary to lift the veneer which is wider than the lifting plate 15, the extension plate 30 is first driven to move away from the lifting plate 15, and the veneer is supported and lifted by the extension plate 30 and the lifting plate 15. Then the bolts 33 are tightened, and the fixing rod 31 is fixed in the fixing groove 32, and the extension plate 30 and the lifting plate 15 are relatively fixed.

[0049] It is worth noting that when the lifting plate 15 is flush with the top surface of the machine 1, the distance between the baffle 6 and the machine 1, and between the baffle 6 and the lifting plate 15 meets the requirements of veneers of various specifications and thicknesses, ensuring that the veneer can be smoothly pushed between the baffle 6 and the machine 1, and between the baffle 6 and the lifting plate 15.

[0050] In addition, soft bristles 35 are fixedly connected to the bottom surface of the baffle plate 6 , and the soft bristles 35 are located at the connection position between the machine platform 1 and the lifting plate 15 .

[0051] The working principle of a veneer splicing device:

[0052] When two pieces of veneer need to be hot-melt spliced, the two pieces of veneer are first placed on the lifting plate 15, and the ends of the two pieces of veneer close to each other are abutted against the two sides of the second partition bar 18. Then the motor 10 is started, the driving shaft of the motor 10 drives the screw rod 11 to rotate, the screw rod 11 drives the adjustment block 14 to move toward the direction close to the machine 1, and the adjustment block 14 further drives the pusher frame 9 to move toward the direction close to the machine 1.

[0053] It should be noted that when the adjustment block 14 moves toward the direction close to the machine 1, the adjustment block 14 drives the second connecting rod 21 to move toward the direction close to the machine 1, and the second connecting rod 21 drives the first connecting rod 20 to swing, and under the guidance of the guide rod 16 and the guide groove 17, the first connecting rod 20 drives the lifting plate 15 to rise, and the lifting plate 15 then drives the two pieces of veneer to rise at the same time. After the veneer exceeds the height of the top surface of the machine 1, the push rack 9 pushes the two pieces of veneer to the conveyor belt 7 at the same time. At this time, the conveyor belt 7 then feeds the two pieces of veneer along the first partition bar 5 into the feed end 3 of the hot melt extrusion splicing module 2, and the hot melt extrusion splicing module 2 hot melts the two pieces of veneer and finally outputs them from the discharge end 4 to complete the splicing of the veneer.

[0054] In summary, by placing two pieces of veneer on the lifting plate 15, the lifting plate 15 lifts the veneer while the pushing rack 9 pushes the veneer to the feeding end 3, which not only avoids the danger caused by people directly pushing the veneer to the feeding end 3, but also the lifting and pushing are carried out simultaneously, which reduces the time of feeding the veneer and improves the efficiency of veneer splicing.

[0055] In addition, when the lifting plate 15 lifts the two pieces of veneer, the baffle 6 blocks and presses the adjacent ends of the veneer, thereby preventing the ends of the veneer from folding when the veneer is fed, thereby improving the quality and stability of the veneer splicing.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
