Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, in particular to a conveying equipment used for processing wood products. Background Art

[0002] Wood products refer to products formed by processing wood raw materials. There are many wooden square toys available, which require multiple processing steps during the production process. They also need to undergo visual inspection during the production process to ensure product quality and prevent inferior products from entering the market.

[0003] There are many existing technologies for wood product processing equipment, such as: Chinese Patent Publication No. CN108910489B discloses a wood product conveying device comprising a conveying mechanism and a transfer mechanism. The conveying mechanism comprises at least three conveying mechanisms, each comprising at least one feed mechanism and at least one discharge mechanism. The conveying mechanism is a roller conveyor belt, one end of which is adjacent to the transfer mechanism, and the transfer mechanism has an adjustable conveying direction. The wood product conveying device provided by this invention utilizes an adjustable conveying direction of the transfer mechanism to enable material flow to be diverted or converged. The feed speed of the next process is adjusted based on the time taken by each process, effectively improving equipment utilization in each process and enhancing production efficiency.

[0004] However, there are still some problems in actual use: 1. Currently, traditional conveying devices lack visual inspection capabilities and are unable to detect surface defects in wood products in real time during material transfer. Products must be transferred to quality inspection after delivery, resulting in intermittent production line stoppages. This "post-inspection" model not only prolongs production cycles but also increases material loss due to rework and repairs, reducing overall production efficiency. 2. The existing visual inspection process relies on manual operation. Workers need to pick up wooden products one by one from the conveyor chute and turn over multiple processed surfaces for detailed inspection. Since the surface of wooden products is extremely smooth after polishing, they are very easy to slip during operation, posing a safety hazard of injuring operators or damaging products.

[0005] In view of this, we propose a conveying device for wood product processing. Summary of the Invention

[0006] The object of the present invention is to provide a conveying device for wood product processing to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention aims to provide a conveying equipment for processing wood products, including a workbench, a conveyor belt is provided on the surface of the workbench, a vertical frame is provided above the conveyor belt, a first cylinder is provided at the bottom of the vertical frame, a piston rod at the end of the first cylinder is provided with a base plate, first racks are provided on both sides of the base plate, a rotating gear is provided between the first rack and the vertical frame, and when the first rack moves in a vertical direction, it drives the rotating gear to engage and rotate, and detection heads are provided on both sides of the center of the base plate, and the detection heads are used to identify the quality of the wood products, and a clamping assembly is provided at the bottom of the base plate, which controls the first cylinder to drive the base plate to move in a vertical direction so that the clamping assembly clamps the wood products moved to the bottom of the vertical frame, and rotating assemblies are provided on both sides of the clamping assembly, and the rotating assembly drives the clamped wood products to rotate so that their processing surface is detected by the detection head, and a protective assembly is provided on the side of the rotating gear away from the first rack, and the protective assembly is used to receive and protect the rotating wood products.

[0008] As a further improvement of this technical solution, a second cylinder is provided on both sides of the bottom of the vertical frame. The piston rod at the end of the second cylinder passes through the vertical frame and a frame is provided at the end. A roller group is provided inside the frame to control the relative movement of the frame and adjust the position of the wooden products moving on the surface of the conveyor belt so that they are in the center of the conveyor belt.

[0009] As a further improvement of the present technical solution, the clamping assembly includes a first motor arranged on the top of the base plate, a main gear is provided at the output end of the first motor, sub-gears are provided on both sides of the main gear, a screw rod is provided at the end of the sub-gear, and a splint is provided on the surface of the screw rod, and the splints move relative to each other when the screw rod rotates.

[0010] As a further improvement of the present technical solution, the rotating assembly includes a turntable provided at the end of the splint, the turntable rotates on the end surface of the splint, and the surface of the turntable is provided with friction lines.

[0011] As a further improvement of the present technical solution, a gear rod is provided at the end of the turntable, and the gear rod passes through the splint to its back. Rotating the gear rod drives the turntable to rotate coaxially.

[0012] As a further improvement of this technical solution, a second motor is provided on one side of the gear rod, and a meshing gear is provided at the output end of the second motor. When the meshing gear rotates, it drives the gear rod to rotate, and the gear ratio of the meshing gear to the gear rod is 8:1.

[0013] As a further improvement of the present technical solution, the protective assembly includes a second rack arranged on one side of the rotating gear, a stretching device is provided at the bottom of the second rack, the free end of the stretching device is connected to a protective seat, a baffle is provided on the side wall of the protective seat, a column is provided on one side of the protective seat, a sliding rod is provided inside the column, the sliding rod is fixed at the end of the protective seat, and the sliding rod drives the protective seat to slide horizontally on the inner wall of the column.

[0014] As a further improvement of the technical solution, a fixed pulley is provided on the side wall of the stand, the fixed pulley is at the same level as the protective seat, and the stretching is connected to the free end of the protective seat through the bottom of the fixed pulley.

[0015] As a further improvement of this technical solution, a compression spring is provided between the column and the slide rod. When the slide rod is squeezed by an external force and slides on the inner wall of the column, it squeezes the compression spring. When the external force disappears, the slide rod is reset by the force of the compression spring.

[0016] As a further improvement of this technical solution, a groove is provided on the surface of the protective seat, a pressure plate is provided in the groove, and a buffer spring is provided between the pressure plate and the groove. When the wooden product falls onto the surface of the pressure plate, the buffer spring buffers the impact force of the wooden product.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In the conveying equipment for processing wood products, the turntable first fits against the wood product when the clamping plates move relative to each other. Since the surface of the turntable is provided with friction grooves, the turntable avoids clamping marks on the surface of the wood product due to over-tightening during the clamping process. When the wood product is clamped between the turntables, the wood product is rotated so that the wood product rotates under the detection head, so that the detection head can identify inferior products with surface defects, thereby increasing the probability of identifying inferior products.

[0018] 2. In the conveying equipment for processing wood products, the meshing gear is driven to rotate coaxially by controlling the output shaft of the second motor. When the meshing gear rotates, the gear rod is driven to rotate. Since a turntable is provided at the end of the gear rod, the wood products clamped between the turntables rotate. Since the meshing gear drives the gear rod to rotate slowly when it rotates, the angular velocity of the wood products clamped between the turntables is slow when they rotate. The detection head can obtain a clear and complete image during the detection of the surface of the wood products, and the labor intensity of the operators is reduced during the automatic rotation detection of the wood products.

[0019] 3. In the conveying equipment for processing wood products, when the base plate moves downward in the vertical direction, the first rack drives the rotating gear to rotate when it moves, and the second rack provided on one side of the rotating gear moves in the opposite direction to the first rack. At this time, the second rack moves upward in the vertical direction. During the movement of the second rack, it drives the stretching to fit the bottom of the fixed pulley and move. At this time, the protective seat connected to the free end of the stretching moves in separate directions, and the sliding rod provided at the end of the protective seat slides on the inner wall of the column and squeezes it, so that it is convenient for the splint to pass through the protective seats to clamp the wood product. When the clamping of the wood product is completed, the first cylinder is controlled to drive the base plate to move upward in the vertical direction. At this time, the protective seat moves in the relative direction to protect the wood product, so as to prevent the rotating wood product from falling and being damaged directly.

[0024] The purpose of this embodiment is to provide a conveying device for wood product processing. Figures 1-8 As shown, it includes a workbench 100, a conveyor belt 101 is provided on the surface of the workbench 100, a stand 102 is provided above the conveyor belt 101, a first cylinder 103 is provided at the bottom of the stand 102, a piston rod at the end of the first cylinder 103 is provided with a base plate 104, first racks 105 are provided on both sides of the base plate 104, a rotating gear 106 is provided between the first rack 105 and the stand 102, and when the first rack 105 moves in the vertical direction, it drives the rotating gear 106 to engage and rotate, and detection heads 107 are provided on both sides of the center of the base plate 104, and the detection heads 107 are used to identify To improve the quality of wooden products, a clamping assembly 300 is provided at the bottom of the base plate 104. The first cylinder 103 is controlled to drive the base plate 104 to move in the vertical direction so that the clamping assembly 300 clamps the wooden products moved to the bottom of the stand 102. Rotating assemblies 400 are provided on both sides of the clamping assembly 300. The rotating assembly 400 drives the clamped wooden products to rotate so that their processed surfaces are detected by the detection head 107. A protective assembly 500 is provided on the side of the rotating gear 106 away from the first rack 105. The protective assembly 500 is used to carry out protection on the rotating wooden products.

[0025] During the conveying process of wooden products, it is necessary to perform visual inspection on their surface to determine whether the processing quality of the wooden products is qualified. In order to facilitate the inspection of wooden products, second cylinders 200 are provided on both sides of the bottom of the stand 102. The piston rod at the end of the second cylinder 200 passes through the stand 102 and is provided with a frame 201 at the end. A roller group 202 is provided inside the frame 201 to control the relative movement of the frame 201 and adjust the position of the wooden products moving on the surface of the conveyor belt 101 so that they are in the center of the conveyor belt 101. When the wooden products move to the center below the stand 102, the piston rod at the end of the second cylinder 200 is controlled to drive the frame 201 to move relative to each other. A roller group 202 is provided inside the frame 201. The roller group 202 rolls and squeezes the wooden products so that the wooden products are in the center of the conveyor belt 101, so that the clamping assembly 300 can quickly clamp the wooden products and perform visual inspection to identify and screen inferior products.

[0026] In order to facilitate the rapid clamping of wooden products, the clamping assembly 300 includes a first motor 301 arranged on the top of the base plate 104, and the output end of the first motor 301 is provided with a main gear 302, and sub gears 303 are provided on both sides of the main gear 302. A screw rod 304 is provided at the end of the sub gear 303, and a clamping plate 305 is provided on the surface of the screw rod 304. When the screw rod 304 rotates, the clamping plates 305 move relative to each other. Since the roller group 202 pushes the wooden product to the center of the surface of the conveyor belt 101, when the piston rod at the end of the first cylinder 103 drives the base plate 104 to move downward in the vertical direction, the wooden product is placed between the clamping plates 305, and the output end of the first motor 301 is controlled to drive the main gear 302 to rotate. When the main gear 302 rotates, it drives the sub gear 303 to engage and rotate. When the sub gear 303 rotates the roller, it drives the screw rod 304 to rotate coaxially. When the screw rod 304 rotates, the clamping plates 305 move relative to each other, so that the wooden product is quickly clamped between the clamping plates 305.

[0027] During the processing, due to the hardness of the wood product, it is easy to crack during processing. During the manual observation process, since the wood product has multiple surfaces, there are blind spots in the field of view during the observation and identification process, resulting in low efficiency in identifying inferior products. Therefore, the rotating component 400 includes a turntable 401 provided at the end of the splint 305. The turntable 401 rotates on the end face of the splint 305. The surface of the turntable 401 is provided with friction lines 402. When the splint 305 moves relatively, the turntable 401 first fits with the wood product. Since the surface of the turntable 401 is provided with friction lines 402, the turntable 401 avoids clamping marks on the surface of the wood product due to excessive clamping during the process of clamping the wood product. When the wood product is clamped between the turntable 401, the wood product is rotated so that the wood product rotates under the detection head 107, so that the detection head 107 can identify inferior products with surface defects, thereby improving the probability of identifying inferior products.

[0028] During the visual inspection of the quality of wooden products, the operator needs to rotate the wooden products to obtain all-round image information for judging whether the product quality is qualified, which leads to high labor intensity for the operator. Therefore, a second motor 404 is provided on one side of the gear rod 403, and a meshing gear 405 is provided at the output end of the second motor 404. When the meshing gear 405 rotates, it drives the gear rod 403 to rotate. The gear ratio of the meshing gear 405 to the gear rod 403 is 8:1. When the wooden product is clamped between the turntables 401, the second motor 404 is controlled to output a gear. The shaft drives the meshing gear 405 to rotate coaxially, and the meshing gear 405 drives the gear rod 403 to rotate when it rotates. Since a turntable 401 is provided at the end of the gear rod 403, the wooden product clamped between the turntables 401 rotates. Since the meshing gear 405 drives the gear rod 403 to rotate slowly when it rotates, the wooden product clamped between the turntables 401 rotates at a slower angular velocity. The detection head 107 can obtain a clear and complete image during the detection of the surface of the wooden product, and the labor intensity of the operator is reduced during the automatic rotation detection of the wooden product.

[0029] When the turntable 401 clamps the wooden product and cooperates with the detection head 107 to perform visual inspection on it, in order to prevent the wooden product from falling and being damaged by collision due to loose clamping, the protection component 500 includes a second rack 501 arranged on one side of the rotating gear 106, and a stretcher 502 is provided at the bottom of the second rack 501. The free end of the stretcher 502 is connected to a protection seat 504, and a baffle 510 is provided on the side wall of the protection seat 504. A column 505 is provided on one side of the protection seat 504, and a sliding rod 506 is provided inside the column 505 for sliding. The sliding rod 506 is fixed to the end of the protection seat 504, and the sliding rod 506 drives the protection seat 504 to slide horizontally on the column The inner wall of the cylinder 505 and the side wall of the stand 102 are provided with a fixed pulley 503, and the fixed pulley 503 is at the same level as the protective seat 504. The stretcher 502 is connected to the free end of the protective seat 504 through the bottom of the fixed pulley 503. A compression spring 507 is provided between the cylinder 505 and the slide bar 506. When the slide bar 506 is squeezed by an external force, the compression spring 507 is squeezed when the slide bar 506 slides on the inner wall of the cylinder 505. When the external force disappears, the slide bar 506 is reset by the force of the compression spring 507. When the base plate 104 moves downward in the vertical direction, the first rack 105 drives the rotating gear 106 to rotate. A second rack 505 is provided on one side of the rotating gear 106. The rack 501 moves in opposite directions to the first rack 105. At this time, the second rack 501 moves upward in the vertical direction. During the movement of the second rack 501, the stretching 502 is driven to fit the bottom of the fixed pulley 503 and move. At this time, the protective seat 504 connected to the free end of the stretching 502 moves in a direction away from each other. The sliding rod 506 provided at the end of the protective seat 504 slides on the inner wall of the column 505 and squeezes it. The opening of the protective seat 504 increases during the movement, so that the splint 305 passes through the protective seat 504 to clamp the wooden product. When the wooden product is clamped, the first cylinder 103 is controlled to drive the base plate 104 to move vertically. The first rack 105 moves upward in the vertical direction. During the movement, the first rack 105 drives the detection head 107 to move downward in the vertical direction. At this time, the tension on the end of the protective seat 504 gradually disappears, and the slide bar 506 is popped out by the force of the compression spring 507, causing the protective seats 504 to move relative to each other, so that the protective seats 504 are under the wooden product under inspection. When the wooden product falls from between the plywood 305, the wooden product is supported by the protective seat 504 to avoid the wooden product directly hitting the ground and causing deformation and damage, thereby improving the safety of visual inspection during the transportation of wooden products.

[0030] In order to reduce the impact force of wooden products falling on the surface of the protective seat 504, a groove is opened on the surface of the protective seat 504, and a pressure plate 508 is provided in the groove. A buffer spring 509 is provided between the pressure plate 508 and the groove. When the wooden product falls on the surface of the pressure plate 508, the buffer spring 509 buffers the impact force of the wooden product. When the wooden product falls on the surface of the pressure plate 508, the pressure plate 508 is subjected to the impact force of the wooden product and squeezes the buffer spring 509, thereby avoiding hard contact between the wooden product and the protective seat 504, thereby buffering the impact force of the wooden product, avoiding damage to the wooden product and the protective seat 504 due to hard contact, and ensuring the quality of the wooden product.

[0031] During specific use, a square wooden product is placed on the surface of the conveyor belt 101, and the height of the wooden product is lower than the protective seat 504. When the wooden product moves to the bottom of the stand 102, the conveyor belt 101 is controlled to stop transmission, and the frame 201 is controlled to move relatively, and the position of the wooden product moving on the surface of the conveyor belt 101 is adjusted so that it is at the center of the conveyor belt 101. When the wooden product moves to the center below the stand 102, the piston rod at the end of the second cylinder 200 is controlled to drive the frame 201 to move relatively. A roller group 202 is provided inside the frame 201. The roller group 202 rolls and squeezes the wooden product so that the wooden product is at the center of the conveyor belt 101, so that the clamping assembly 300 can quickly clamp the wooden product and perform visual inspection to identify and screen inferior products. The piston rod at the end of the first cylinder 103 drives the base plate 104 to move downward in the vertical direction, so that the wooden product is placed between the clamping plates 305. The output end of the first motor 301 is controlled to drive the main gear 302 to rotate. When the main gear 302 rotates, it drives the sub-gear 303 to mesh and rotate. When the sub-gear 303 rotates the roller, it drives the screw rod 304 to rotate coaxially. When the screw rod 304 rotates, the clamping plates 305 move relative to each other, so that the wooden product is quickly clamped between the clamping plates 305. When the clamping plates 305 move relative to each other, the turntable 401 first contacts the wooden product. Since the turntable 401 has friction lines 402 on its surface, the turntable 401 prevents the wooden product from being clamped too tightly, thereby preventing clamping marks from being formed on the wooden product surface. When the wooden product is clamped between the turntables 401, the wooden product is rotated so that the wooden product rotates under the detection head 107. Thus, the detection head 107 can identify inferior products with surface defects, thereby improving the probability of identifying inferior products. The output shaft of the second motor 404 is controlled to drive the meshing gear 405 to rotate coaxially. When the meshing gear 405 rotates, the gear rod 403 is driven to rotate. Since a turntable 401 is provided at the end of the gear rod 403, the wooden product clamped between the turntables 401 rotates. Since the meshing gear 405 drives the gear rod 403 to rotate slowly when rotating, the angular velocity of the wooden product clamped between the turntables 401 is slow when rotating. The detection head 107 can obtain a clear and complete image during the detection of the wooden product surface, reducing the labor intensity of the operator during the automatic rotation detection of the wooden product. When the base plate 104 moves downward in the vertical direction, the first rack 105 drives the rotating gear 106 to rotate when it moves. The second rack 501 provided on one side of the rotating gear 106 moves in the opposite direction to the first rack 105. At this time, the second rack 501 moves upward in the vertical direction. During the movement of the second rack 501, it drives the stretching 502 to fit the bottom of the fixed pulley 503 and move. At this time, the protective seat 504 connected to the free end of the stretching 502 moves in the direction of separation. The sliding rod 506 provided at the end of the protective seat 504 slides on the inner wall of the column 505 and squeezes it. The opening of the protective seat 504 increases during the movement, so that it is convenient for the splint 305 to pass through the protective seat 504 to clamp the wooden product. When the clamping is completed, the first cylinder 103 is controlled to drive the base plate 104 to move up in the vertical direction. At this time, the first rack 105 moves upward in the vertical direction. During the movement, the first rack 105 drives the detection head 107 to move downward in the vertical direction by rotating the gear 106. At this time, the tension on the end of the protective seat 504 gradually disappears, and the slide bar 506 is ejected by the force of the compression spring 507, causing the protective seats 504 to move relative to each other, so that the protective seats 504 are under the wooden product being inspected. When the wooden product falls from between the splints 305, the wooden product is supported by the protective seat 504 to prevent the wooden product from directly hitting the ground and causing deformation and damage, thereby improving the safety of visual inspection during the transportation of wooden products.
