Description

Technical Field

[0001] This utility model relates to the field of particleboard processing technology, specifically to a particleboard processing device. Background Technology

[0002] After the particleboard is hot-pressed, it needs to be cooled. Currently, a cooling plate machine is used to receive and cool the particleboards in batches.

[0003] For example, CN213674549U addresses the issue that during the board feeding process, due to the weight of the board itself, the friction between it and the cooling rack is relatively large, making it difficult for the board to slide quickly and smoothly to the base of the cooling rack, resulting in an unstable feeding process. Furthermore, the friction between the board and the cooling rack makes the surface of the board easily scratched, affecting the processing quality of the board.

[0004] The above solution uses rollers on each cooling rack to deliver the granular boards to their designated positions. This results in a complex overall structure with too many parts, which significantly increases the workload and cost of later maintenance and inspection.

[0005] Based on this, this solution provides a particleboard processing device that eliminates the need for rollers on each cooling rack for placement and delivery. Instead, it utilizes an intermittent pushing mechanism at the feeding end of the cooling rack to push the particleboards on the flat cooling rack, thereby actively delivering the particleboards into place. Utility Model Content

[0006] (a) Technical issues

[0007] The present invention aims to at least solve the problem that the existing technology of setting rollers on each set of cooling racks will result in a large amount of maintenance work in the later stage.

[0008] (II) Technical Content

[0009] This solution provides a particleboard processing device, achieved through the following specific technical means, including:

[0010] A belt cooling plate device has several sets of cooling plate frames distributed along the length of the conveyor belt. Each set of cooling plate frames consists of several sets of cooling plate rods along the width of the conveyor belt.

[0011] The grid platform, fixed to the front end of the frame of the belt cooler, consists of a set of crossbars on the front side and multiple sets of longitudinal bars that are evenly spaced along the length of the crossbars. The gaps between adjacent longitudinal bars allow the cooler rods to pass through.

[0012] The formed granular board is conveyed to the grid platform, and when the cooling plate rod rotates to a horizontal position, it is exactly positioned in the gap between the longitudinal bars to support the granular board.

[0013] An intermittent pushing mechanism is also located at the front end of the frame of the belt cooler. The intermittent pushing mechanism consists of an intermittent upper swing assembly mounted on the frame and a pushing wheel assembly mounted on the front end of the intermittent upper swing assembly.

[0014] The pusher wheel assembly includes a horizontal shaft rotatably mounted on the front end of the intermittent upward swing assembly and multiple sets of feeding wheels fixedly sleeved on the horizontal shaft. The front end of the intermittent upward swing assembly is located below the grid platform. The intermittent upward swing assembly is used to intermittently drive the horizontal shaft to swing upward close to the bottom wall of the grid platform, so that the upper part of the feeding wheel extends out from the gap between the longitudinal bars and contacts the particle plate.

[0015] A motor is also installed at the end of the intermittent swing assembly, with its shaft end fixed to the horizontal shaft, to drive the feed wheel to rotate.

[0016] Preferred technical solution 1: No feeding wheel is provided on the horizontal axis at the position directly opposite the cooling plate rod to avoid motion interference between the two.

[0017] Preferred technical solution 2: The intermittent upward swing assembly includes a second motor mounted on a frame, and a set of cranks fixed to the shaft end of the second motor. A front frame fixed to the side of the grid platform is located below the grid platform on the frame, and a swing rod is hinged to the front frame below the grid platform. A push wheel set is installed at the front end of the swing rod, and a connecting rod is hinged to the tail end of the swing rod. The tail end of the connecting rod is rotatably connected to the free end of the crank. When the second motor rotates, it will drive the crank to rotate, and then use the connecting rod to pull the swing rod to swing up and down.

[0018] Preferred technical solution 3: A linkage component is connected between the shaft of the second motor and the roller shaft of the front set of belt rollers. The linkage component is used to transmit the power of the second motor to the set of belt rollers and is used to intermittently drive the belt rollers to rotate.

[0019] Preferred technical solution four: The linkage component includes a linkage disc fixedly sleeved on a set of roller shafts on the front side, a fan-shaped limiting plate fixedly sleeved on the second shaft of the motor, and a linkage handle also fixed on the second shaft of the motor, with a set of protruding columns at the end of the linkage handle;

[0020] Multiple sets of fan-shaped notches and an equal number of deep U-shaped notches are provided on the side of the linkage plate. When the motor rotates, the fan-shaped limiting plate slides intermittently across the adjacent fan-shaped notches, while the protruding column slides intermittently across the adjacent deep U-shaped notches. The fan-shaped limiting plate and the protruding column are staggered and approach the linkage plate.

[0021] Preferred technical solution five: The included angle between two adjacent sets of fan-shaped notches and two adjacent sets of deep U-shaped notches on the linkage plate is the same as the included angle between a set of cooling racks in a flat state and another set of cooling racks adjacent to it.

[0022] (III) Technical Effects

[0023] The above structure gives this solution the following advantages:

[0024] 1. Instead of the traditional method of setting up a large number of rollers on the cooling rack to push the granular plates into place, an intermittent pushing mechanism is set at the front end of the frame, that is, the bottom side of the grid platform, to push the granular plates into place one by one.

[0025] 2. During the process of pushing the particleboard into place on the cooling rack, the surface of the particleboard should avoid contact with the cooling rack, so that the surface of the particleboard is not easily damaged.

[0026] The traditional method of setting a large number of rollers on the cooling rack means that if any roller malfunctions and cannot rotate, it will directly slide against the surface of the particleboard.

[0027] 3. By using a linkage component, the alternating motion of the belt roller and the feeding wheel in the original belt cooling machine is realized, which reduces the amount of power equipment required and also avoids problems with the coordination between the two as much as possible.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-3 The particleboard processing device includes a belt cooler 1, a grid platform 2 and an intermittent pushing mechanism 3. The belt cooler 1 adopts a traditional structure, that is, the front and rear ends of its frame 11 are rotatably mounted with belt rollers 13, and a conveyor belt 12 is placed between the two sets of belt rollers 13. Several sets of cooler frames 14 are distributed along the length of the conveyor belt 12. Each set of cooler frames 14 is composed of several sets of cooler rods 141 fixed along the width of the conveyor belt 12.

[0037] The side of the grid platform 2 is fixed to the front frame 111 of the frame 11 of the belt cooler 1. The grid platform 2 consists of a set of horizontal bars 21 on the front side and multiple sets of vertical bars 22 that are evenly spaced along the length of the horizontal bars 21. The tail end of the vertical bars 22 extends backward to a position close to a set of belt rollers 13 at the front end of the belt cooler 1. The gap formed between adjacent vertical bars 22 is used for the cooling bar 141 to pass through, that is, the width of the gap is not less than the width of the cooling bar 141.

[0038] In use, the formed granules are first conveyed to the grid platform 2. As the belt roller 13 rotates, the conveyor belt 12 drives the cooling plate frame 14 to rotate from the bottom side to the top side of the grid platform 2. When the cooling plate rod 141 rotates to the horizontal state, it is exactly in the gap between the corresponding sets of longitudinal rods 22. At this time, the cooling plate frame 14 and the grid platform 2 are in the same plane. As the belt roller 13 continues to rotate, the cooling plate frame 14 passes through the gap between the longitudinal rods 22 to lift the granules on the grid platform 2 and convey them to the rear for cooling.

[0039] The intermittent pushing mechanism 3 is also located at the front end of the frame 11 of the belt cooler 1. The intermittent pushing mechanism 3 consists of an intermittent upper swing assembly 31 mounted on the frame 11 and a pushing wheel assembly 32 mounted on the front end of the intermittent upper swing assembly 31.

[0040] The push wheel assembly 32 includes a horizontal shaft 321 rotatably mounted on the front end of the intermittent upward swing assembly 31 and multiple sets of feeding wheels 322 fixedly sleeved on the horizontal shaft 321. The front end of the intermittent upward swing assembly 31 extends to the lower part of the front of the grid platform 2. The intermittent upward swing assembly 31 is used to intermittently drive the horizontal shaft 321 to swing upward close to the bottom wall of the grid platform 2. When the horizontal shaft 321 is close to the bottom wall of the grid platform 2, the upper part of each set of feeding wheels 322 extends out from the gap of the corresponding set of longitudinal rods 22 and contacts the bottom wall of the granular plate on the horizontal cooling plate frame 14. It can slightly lift the front end of the granular plate so that its bottom wall is slightly away from the cooling plate frame 14. At this time, the granular plate contacts the cooling plate frame by its tail end. When the feeding wheel 322 rotates and pushes the granular plate, it can reduce frictional resistance. Even if there is a slight scratch, only the head end will be damaged. The edge will be removed in subsequent processing and will not affect the overall quality.

[0041] A motor 323 with its shaft end fixed to the horizontal shaft 321 is also installed at the end of the intermittent swing assembly 31. This motor drives the feeding wheel 322 to rotate, so that when the feeding wheel 322 contacts the granule plate, it can actively push the granule plate backward and move closer to the conveyor belt 12.

[0042] In the size setting, the radius of the feeding wheel 322 is greater than the thickness of the grid platform 2 and the cooling rack 14 to ensure that the feeding wheel 322 can extend out of the gap. At the same time, the width of the feeding wheel 322 is also smaller than the width of the gap directly opposite to ensure that the feeding wheel 322 will not collide with the gap wall when it is lifted.

[0043] Meanwhile, no feeding wheel 322 is provided on the horizontal axis 321 at the position directly opposite to the cooling plate rod 141 to avoid motion interference between the two.

[0044] Please see Figures 2-5 The particleboard processing device includes an intermittent swing assembly 31, which comprises a second motor 311 fixedly mounted on a frame 11. A set of cranks 312 are fixed to the shaft end of the second motor 311. A swing arm 313 is located on the front frame 111 below the grid platform 2. The middle of the swing arm 313 is hinged to the front frame 111. A horizontal shaft 321 is rotatably mounted on the front end of the swing arm 313. A first motor 323 is also fixed to the front end of the swing arm 313. A set of connecting rods 3 are hinged to the tail end of the swing arm 313. 14. The tail end of the connecting rod 314 is rotatably connected to the free end of the crank 312. When the motor 311 rotates, it will drive the crank 312 to rotate, and then use the connecting rod 314 to pull the swing rod 313 to swing up and down. When the front end of the swing rod 313 swings to the highest point, the upper part of the feeding wheel 322 extends out from the gap of the corresponding longitudinal rod 22 and contacts the bottom wall of the particle plate on the horizontal cooling plate frame 14, and slightly lifts the front end of the particle plate. When the front end of the swing rod 313 swings to the lowest point, the feeding wheel 322 moves away from the grid platform 2.

[0045] When each set of cooling racks 14 rotates to the flat position, there will be a period of stillness. During this time, motor 2 311 drives crank 312 to rotate and controls the feeding wheel 322 to complete the lifting and lowering of the plate.

[0046] The distance between the horizontal axis 321 and a set of belt rollers 13 on the front side of the belt cooler 1 is greater than the distance between the end of the cooler rod 141 and the set of belt rollers 13, thereby ensuring that the horizontal axis 321 will not interfere with the cooler rod 141.

[0047] Please see Figures 3-5 In the particleboard processing device, a linkage component 4 is connected between the shaft of motor 2 311 and the roller shaft of a set of front rollers 13. The linkage component 4 is used to transmit the power of motor 2 311 to the set of rollers 13, thereby driving the set of rollers 13 to rotate, and thus achieving the technical effect of driving the conveyor belt 12 to rotate.

[0048] Furthermore, the linkage component 4 is used to intermittently drive the belt roller 13 to rotate. That is, when the motor 2 311 rotates one revolution, it first drives a set of cooling plate frames 14 on the conveyor belt 12 to rotate to a flat position. During this process, the plate feeding wheel 322 is located below the grid platform 2 and does not contact the particle plate.

[0049] Before the feeding wheel 322 moves up to contact the granule plate, and until the feeding wheel 322 contacts the granule plate for a certain period of time, the linkage component 4 will not drive the belt roller 13 to rotate, thereby realizing the sequential completion of the flat placement action of the cooling plate frame 14 and the backward pushing action of the granule plate. During the time before the feeding wheel 322 moves down away from the grid platform 2 to the lowest end and moves up from the lowest end to approach the grid platform again, the linkage component 4 drives the conveyor belt 12 to rotate through the rotation of the belt roller 13, thus achieving the technical effect of driving the lower set of cooling plate frames 14 to the flat position.

[0050] The linkage assembly 4 includes a linkage disc 41 fixedly sleeved on a set of rollers 13 on the front side, a fan-shaped limiting plate 42 fixedly sleeved on the shaft of motor 2 311, and a linkage handle 43 also fixed on the shaft of motor 2 311. At the end of the linkage handle 43, there is a set of protruding posts 431, the diameter of which is equal to the width of the deep U-shaped notch 412.

[0051] A fan-shaped notch 411 and a deep U-shaped notch 412 are provided on the side of the linkage disk 41. The fan-shaped notch 411 and the deep U-shaped notch 412 are evenly and staggered along the circumference of the side of the linkage disk 41. The protruding column 431 on the linkage handle 43 is located at the notch position of the fan-shaped limiting plate 42. When the motor 311 rotates, the fan-shaped limiting plate 42 and the protruding column 431 intermittently slide past the fan-shaped notch 411 and the deep U-shaped notch 412. That is, during the time when the fan-shaped limiting plate 42 slides into and out of a set of fan-shaped notches 411, the linkage disk 41 is limited. At this time, the linkage disk 41 does not rotate. That is, the belt roller 13 connected to it is in a stationary state. During this stationary time, the end of the crank 312 rotates in the middle front half position. That is, the feeding wheel 322 is in the state of lifting up and approaching the particle plate, contacting and pushing the particle plate, and then slightly moving away from the particle plate.

[0052] When the fan-shaped limiting ring leaves the fan-shaped notch 411, the protruding column 431 is driven by the linkage handle 43 to rotate into a set of deep U-shaped notches 412 adjacent to the fan-shaped notch 411. During the time it takes for the protruding column 431 to slide into and out of the deep U-shaped notch 412, the protruding column 431 will push the linkage disk 41 to rotate at a set angle, thus completing the upward and flattening of a set of cooling plate racks 14 on the bottom side. The originally flat cooling plate rack 14 supports the particle plate pushed into place by the feeding wheel 322 and moves it upward.

[0053] During the rotation time of the linkage disc 41, the crank 312 rotates from the end to the middle and rear half of its stroke, that is, the feed plate wheel 322 is in the state of moving down away from the grille platform 2 to the lowest end, and then moving up from the lowest end to approach the grille platform 2.

[0054] Please see Figure 1 The particleboard processing device has the same angle between two adjacent sets of fan-shaped notches 411 and two adjacent sets of deep U-shaped notches 412 on the linkage disk 41 as the angle between a set of cooling board frames 14 in a flat position and another set of cooling board frames 14 adjacent to it. This enables the motor 311 to perform a flat position action of the cooling board frame 14 once every rotation, and a pushing and resetting action of a feeding wheel 322.

[0055] It is worth noting that the belt cooling plate device 1, motor 1 323, motor 2 311 mentioned in this embodiment, as well as their matching power supply and control switch, can also be provided by the manufacturer. The circuits, electronic components and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and there is no need to elaborate.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
