Abstract

The present application relates to the field of rubber wood finger joint processing, especially to a high-efficiency comb tooth machine for rubber wood finger joint processing. The traditional comb tooth equipment needs manual assistance to turn the wood, which is low in efficiency and affects the quality.

The high-efficiency comb tooth machine for rubber wood finger joint processing comprises a mounting table and the like. Two comb tooth machines and a conveying assembly are arranged on the mounting table. The cutter heads of the two comb tooth machines are male and female and are engaged with each other. An electric sliding table is slidably connected to the mounting table. The rubber wood rod is blocked and limited at one end by the blocking, so that the ends of the rubber wood rod are flush. The rubber wood rod is limited by the limiting pressing plate during the comb tooth process to prevent displacement. The rubber wood rod can be automatically aligned and limited at both ends, and continuous automatic comb tooth processing can be realized to improve the work efficiency.

Description

Technical Field

[0001] This invention relates to the field of rubberwood finger jointing, and more particularly to a high-efficiency combing machine for rubberwood finger jointing. Background Technology

[0002] In the automated production of rubberwood finger-jointed boards, the combing process is a crucial step determining the finger joint strength and processing efficiency. Traditional combing equipment typically requires manual assistance to turn the rubberwood rods around, manually align the wood ends, and perform two separate clamping and processing steps when combing the ends (male and female tenons). Manual alignment has low precision, easily leading to misalignment of the teeth, affecting finger joint quality. Furthermore, the step-by-step processing is inefficient and labor-intensive, making it difficult to meet the demands of continuous mass production. Existing equipment generally uses multiple belt conveyors, barriers, and clamping limit devices to align and limit the ends of the rubberwood rods. However, this equipment occupies a large area, requires ample workshop space, and the transmission and positioning mechanisms are relatively separate, resulting in poor coordination and a tendency for wood misalignment or inaccurate positioning. Summary of the Invention

[0003] To address the shortcomings or deficiencies of the existing technologies, this invention provides a high-efficiency combing machine for rubberwood finger joints. It requires less workshop space and can achieve automatic alignment and limiting of both ends of the rubberwood rod without manual turning or intervention throughout the entire process, enabling continuous automated combing and improving work efficiency.

Both ends of the two barriers have straight grooves, and arc-shaped locking blocks are fixedly connected to the two straight grooves on the barriers. Two arc-shaped locking blocks located on the same barrier form a group. Four limiting protrusions are fixedly connected to the material feeding frame, two limiting protrusions located at the same end of the material feeding frame form a group, and the two limiting protrusions in the same group are respectively located in the straight grooves at both ends of the barriers. Each of the four limiting protrusions has a locking groove, and the four arc-shaped locking blocks are respectively located in the four... Within the slot on the limiting protrusion, torsion frames are slidably connected to the inner sides of both ends of the barrier. Torsion springs are connected between the material handling frame and the four torsion frames. An electric push rod is fixedly connected to the mounting ring, and a rack is slidably connected to the mounting ring. The telescopic rod of the electric push rod is fixedly connected to the rack. Gears are fixedly connected to both ends of the barrier. The gears pass through the mounting ring and mesh with the rack. Two gears located on the same barrier form a group. Four push frames are slidably connected to the material handling frame. An inclined block is provided on the top of each push frame. Two push frames located at the same end of the material handling frame form a group. Several tension springs are connected between the material handling frame and the four push frames. A top rod is fixedly connected to each push frame. Arc-shaped frames are fixedly connected to the inner sides of both ends of the barrier, and the arc-shaped frames contact the top rod.

[0008] The beneficial effects of this invention are as follows: by tilting the material handling frame and using a vibrating motor to slide the wood towards the barrier, one end of the rubberwood rod is precisely blocked and limited to ensure that the end face is flush; subsequently, the limiting pressure plate presses the wood throughout the combing process to prevent displacement, while the material blocking mechanism moves in conjunction to avoid processing space, and the electric slide table drives the rubberwood rod through two combing machines to complete the combing of the male and female tenons. The entire process does not require manual turning or intervention, thereby achieving automatic alignment and limiting of both ends of the rubberwood rod, continuous automated combing processing, and improving work efficiency.

A rack 59 is slidably connected to the mounting ring 53. The telescopic rod of the electric push rod 58 is fixedly connected to the rack 59. Gears 510 are fixedly connected to both ends of the barrier 54. The gears 510 pass through the mounting ring 53 and mesh with the rack 59, located on the same barrier 5. The two gears 510 on the 4 form a group. Four pushers 511 are slidably connected to the material handling frame 41. The top of each pusher 511 is provided with a sloping block. The two pushers 511 located at the same end of the material handling frame 41 form a group. Several tension springs 512 are connected between the material handling frame 41 and the four pushers 511.

[0024] The pressing mechanism includes a fixed frame 61. Four fixed frames 61 are fixedly connected to the top of the material handling frame 41. Two fixed frames 61 located at the same end of the material handling frame 41 form a group. Four hydraulic cylinders 62 are provided on the material handling frame 41. Two hydraulic cylinders 62 located at the same end of the material handling frame 41 form a group. A pressing slide plate 63 is slidably connected between two fixed frames 61 in the same group. The bottoms of the two pressing slide plates 63 are fixedly connected to the piston rods of the two groups of hydraulic cylinders 62, respectively. A limiting pressure plate 64 is slidably connected to the sliding plate 63. A spring plate 65 is slidably connected to the limiting pressure plate 64. Several downward pressure springs 651 are connected between the spring plate 65 and the downward pressure sliding plate 63.

The bottom of one end of the pressure frame 66 contacts the inclined block at the top of the push frame 511. Two compression springs 67 are connected between the material handling frame 41 and each of the four pressure frames 66.

[0025] Initially, the arc-shaped locking block 541 is located in the slot on the limiting protrusion 55. The limiting protrusion 55 limits the stop 54 through the arc-shaped locking block 541. First, the worker places several rubberwood rods 411 in the material handling frame 41. Then, the two electric sliders 432 will drive the two lifting seats 44 and the two lifting frames 45 to move away from the conveying component 21. The movement of the lifting frames 45 will drive the lifting protrusion 46 and the swinging protrusion 47 to move away from the conveying component 21. During the movement, the swinging protrusion 47 will move downward under the guidance of the swinging chute 461. The downward movement of the swinging protrusion 47 will drive the lifting frame 45 and the lifting protrusion 46 to move downward. The downward movement of the lifting protrusion 46 will squeeze the material handling frame 41 to swing downward. The material handling frame 41 vibrates under the action of the vibrating motor 48. The rubberwood rods 411 inside the material handling frame 41 slide down along the inclined angle of the frame under the action of vibration. One of the barriers 54 blocks several rubberwood rods 411, aligning one end of each rod. Then, the vibrating motor 48 stops running, and one set of hydraulic cylinders 62 drives one of the downward pressing slide plates 63 to move downwards. The downward movement of the downward pressing slide plate 63 causes one of the limiting pressure plates 64, one of the spring plates 65, and the pressing spring 651 to move downwards. One of the limiting pressure plates 64 presses and limits one end of each rubberwood rod 411, and one of the spring plates 65 contacts one of the pressing frames 66. As one of the sets of... Hydraulic cylinder 62 drives one of the downward sliding plates 63 to continue moving downward. One of the downward sliding plates 63 drives one of the spring plates 65 to continue moving downward via the downward spring 651. The downward spring 651 is compressed. The downward movement of one of the spring plates 65 pushes one of the pressure frames 66 to move downward. The compression spring 67 is compressed. The downward movement of one of the pressure frames 66 compresses one of the push frames 511 to move. The tension spring 512 is stretched. The movement of the push frame 511 drives the push rod 513 to move. The movement of the push rod 513 drives the arc frame 514 to move. The movement of the two arc frames 514 in the same group will jointly drive one of the stops 54, one of the arc-shaped locking blocks 541, one of the mounting rings 53, and two of the gears 510 to move. As the machine moves, one of the barriers 54 will disengage from the rubberwood rod 411, and the arc-shaped locking block 541 will disengage from the slot on the limiting protrusion 55. Then, the electric push rod 58 will drive the rack 59 to move downward. The downward movement of the rack 59 will drive the gear 510 to rotate. The rotation of the two gears 510 in the same group will jointly drive one of the barriers 54, the torsion frame 56, and the arc-shaped frame 514 to rotate downward by 90°. The part of several rubberwood rods with one end flat to one end of the material handling frame 41 is the part of the combing machine 2 that combs the rubberwood rod 411. At this time, one end of the rubberwood is at the same level as the cutter head of the combing machine 2. Then, the electric slide table 3 will drive the material handling frame 41, the barrier 54, and the rubberwood rod 411 to move horizontally. One of the combing machines 2 will then contact one end of the rubberwood rod 411.And comb teeth are applied to one end of the rubberwood rod 411; When one of the combing machines 2 completes combing one end of the rubberwood rod 411, the electric slider 432 drives the lifting seat 44, lifting frame 45, lifting cam 46, and swing cam 47 to move towards the conveying assembly 21, causing the material handling frame 41 and the rubberwood rod 411 to swing upwards. Then, one of the hydraulic cylinders 62 drives one of the pressing slide plates 63, one of the limiting pressure plates 64, one of the spring plates 65, and the pressing spring 651 to move upwards and reset. The pressing spring 651 resets, one of the spring plates 65 disengages from one of the pressure frames 66, and the compression spring 67 resets. The reset of the compression spring 67 drives one of the pressure frames 66 to move upwards and reset, and the pressure frame 66 disengages from the push frame 511, stretching... Spring 512 will reset. The reset of tension spring 512 will drive pusher 511 to move in the opposite direction and reset. The reset of pusher 511 will drive top rod 513 to move in the opposite direction and reset. Then, limit pressure plate 64 will disengage from several rubberwood rods 411. Then, electric push rod 58 will drive rack 59 to move upward. The upward movement of rack 59 will drive gear 510 to rotate in the opposite direction. The rotation of two gears 510 in the same group will jointly drive one of the blocks 54, two arc-shaped frames 514 in the same group, two torsion frames 56 in the same group, and two arc-shaped locking blocks 541 in the same group to swing upward and reset. Torsion spring 57 will reset. When arc-shaped locking block 541 swings to align with the slot on limit protrusion 55, reset spring 52 will reset. 2. The reset will cause the slide bar frame 51, mounting ring 53, barrier 54, and arc frame 514 to move and reset in the opposite direction. The arc block 541 will re-engage into the limiting groove on the limiting protrusion 55. At the same time, the vibration motor 48 will start, and several rubberwood rods 411 in the material handling frame 41 will slide down to the other end of the material handling frame 41 under the action of the vibration motor 48. Another barrier 54 will block several rubberwood rods 411, so that the other ends of several rubberwood rods 411 are aligned. Then the vibration motor 48 stops running, and another set of hydraulic cylinders 62 will drive another pressing slide plate 63, another limiting pressure plate 64, another spring plate 65, and the pressing spring 651 to move downward, so that the other spring plate 65 pushes another set of pressure frames. As the pressure frame 66 moves downward, the compression spring 67 is compressed. The downward movement of the pressure frame 66 forces the pusher 511 to move, stretching the tension spring 512. The movement of the pusher 511 drives the top rod 513 to move, which in turn pushes the arc-shaped frame 514 to move. The two arc-shaped frames 514 in the other set together move another stop 54, another set of arc-shaped locking blocks 541, another set of mounting rings 53, and two other gears 510, causing the other set of arc-shaped locking blocks 541 to disengage from the slots on the other set of limiting protrusions 55. Immediately afterwards, another set of electric push rods 58 drives the rack 59 to move downward. The downward movement of the rack 59 drives the gears 510 to rotate, and the two gears 510 in the other set together cause the other stop 54 to swing downward.This causes the portion of several rubberwood rods 411 with their other end plane extending to one end of the material handling frame 41 to be the part where the combing machine 2 combs the rubberwood rods 411. At this time, one end of the rubberwood is at the same level as the cutter head of the combing machine 2. Then, the electric slide table 3 drives the material handling frame 41, the barrier 54, and the rubberwood rods 411 to move horizontally in the opposite direction to reset. During the reset process, another combing machine 2 will comb the other end of the rubberwood rods 411. Finally, another set of hydraulic cylinders 62 will drive another downward sliding plate 63, another limit pressure plate 64, another spring plate 65, and the downward pressure spring 651 to move upward to reset. The downward pressure spring 651 will reset, and the spring plate 65 will disengage from the other set of pressure frames 66. The compression spring 67 will reset, and the reset of the compression spring 67 will drive the other set of pressure frames 66 to move upward to reset. When the pusher 511 disengages from the pusher 512, the tension spring 512 resets, causing the pusher 511 to move in the opposite direction and reset. The reset of the pusher 511 then causes the top rod 513 to move in the opposite direction and reset. The limiting plate 64 disengages from all the rubberwood rods 411. At this point, the vibrating motor 48 restarts, and the rubberwood rods 411 in the feed frame 41 slide down onto the conveying assembly 21 for transport. Thus, by blocking and limiting one end of the rubberwood rod 411 with the baffle 54, one end of the rubberwood rod 411 is kept flush. Simultaneously, the limiting plate 64 limits the rubberwood rod 411 during the combing process, preventing displacement. This enables automatic alignment and limiting of both ends of the rubberwood rod 411, continuous automated combing, and improved work efficiency.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
