Description

Technical Field

[0001] The invention relates to the technical field of particleboard processing, in particular to an energy-saving single-channel particleboard drying system. Background Art

[0002] Particleboard is a man-made board made from wood chips (also known as shavings). After careful screening and glue mixing, specialized equipment applies an appropriate amount of adhesive, and the board is pressed under high temperature and high pressure. Due to its unique advantages, such as a wide range of raw material sources, relatively low cost, excellent strength-to-weight ratio, and ease of secondary processing, it has found widespread and important applications in a variety of fields, including architectural decoration, furniture manufacturing, and packaging materials. It has become an indispensable foundational material in modern industrial production.

[0003] In the particleboard production process, drying is a critical step in ensuring board quality. Currently, the industry's most commonly used drying method involves using a drying drum for both ends. Specifically, the particleboard to be dried is placed horizontally within the drying drum. Heat sources at both ends of the drum release heat, allowing hot air to circulate within the drum, effectively drying the particleboard.

[0004] However, this seemingly reasonable design has exposed some problems in actual application. Since the particleboard is arranged horizontally in the drying cylinder, and the heat source is usually set at both ends of the drying cylinder, the particleboard in the middle area is relatively far away from the heat source, while the particleboard on both sides is closer to the heat source. This difference in spatial position causes the degree of heat transfer to the particleboard in different positions to be significantly different during the flow of hot air. The particleboards on both sides close to the heat source can absorb heat more directly and fully, and the drying speed is relatively fast; while the particleboard in the middle is farther away from the heat source, the heat transfer efficiency is low, and the drying speed is relatively slow. The end result is that there are significant differences in the drying effects of different parts of the entire particleboard. The middle may not have reached the ideal drying level, while the two sides have been over-dried. This not only affects the overall quality of the particleboard, but may also have an adverse effect on subsequent processing and performance. Summary of the Invention

[0005] In order to overcome the disadvantage of using traditional drying cylinders to dry particleboards, where the particleboards in the middle and on both sides are heated unevenly, resulting in different drying effects on different parts of the particleboards, the technical problem to be solved is to provide an energy-saving single-channel particleboard drying system.

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the present invention.

[0028] Example: An energy-saving single-channel particleboard drying system, such as Figures 1-9 As shown, it includes a drying box 1, a first fan 5, a feed port 101 and a discharge port 102 are opened on the side of the drying box 1, and the first fan 5 is set on one side of the drying box 1. It also includes an endless conveyor belt 2, a material loading plate 4, a material flip plate 6, a limit assembly, a gear 8 and a rack 9. The endless conveyor belt 2 is composed of a chain 3 and a loading plate 4. The chain 3 is located in the middle of the inner cavity of the drying box 1. The chain 3 is driven to rotate by a motor. The loading plate 4 is fixed to the chain 3 by a buckle and is arranged at equal distances. The material flap 6 is rotatably connected to the material loading plate 4. A gear 8 is provided at the end of the rotating shaft of the material flap 6. A rack 9 that can mesh with the gear 8 is fixed to the inner wall of the drying box 1. The particle board is placed at the material flap 6. The motor drives the chain 3 to rotate to drive the material loading plate 4 to rotate. When the material loading plate 4 moves to the point where the gear 8 meshes with the rack 9, the material flap 6 rotates. The two sides of the material flap 6 are hinged with limit rollers 7 that are inclined toward each other. The hinge of the limit roller 7 The limit plates 71 are connected to the material flap 6 by sliding grooves, and the front ends of the limit plates 71 are fixedly connected to the guide plates 72. When the width of the particle board is adjusted, the two sides of the particle board are squeezed and contacted with the guide plates 72, thereby pushing the corresponding limit plates 71 to move in the directions away from each other, so that the limit plates 71 drive the limit rollers 7 to rotate adaptively, so as to swing synchronously to the appropriate angle to limit and guide the particle board. The flipped particle board can be dried by the first fan 5. The gear ratio of the rack 9 to the gear 8 is 1:2. The rack 9 is arranged at intervals from left to right, so that the material flap 6 can intermittently flip 180 degrees, so that the hot air from the first fan 5 can improve the drying effect on both sides of the particle board.

[0029] like Figure 4and Figure 5 As shown, the feeding mechanism is also included, which includes a feeding belt 10, a feeding plate 11, a servo motor 14 and a feeding roller 15. The feeding plate 11 is fixed to the side of the drying box 1 and is located at a corresponding position of the feed port 101. The feeding belt 10 is arranged on the side of the drying box 1 to connect with the feeding plate 11. The servo motor 14 is fixed to the side of the drying box 1 through a fixed seat. The output shaft of the servo motor 14 is connected to the feeding roller 15. The rubber contact 16 is axially slidably connected to the feeding roller 15. An elastic member is connected between the rubber contact 16 and the feeding roller 15. The elastic member is a spring. The feeding roller 15 is located above the feeding plate 11. like Figure 4 and Figure 5 As shown, it also includes a wedge contact plate 12, a return spring 1201 and an induction plate 13. The wedge contact plate 12 is slidably connected to the feed plate 11 and a return spring 1201 is connected between the two. The induction plate 13 is arranged at the end of the feed plate 11. When the wedge contact plate 12 contacts the induction plate 13, the induction plate 13 will control the servo motor 14 to start.

[0030] like Figure 6 and Figure 7 As shown, it also includes an electric slide rail 17 and an electric push rod 18. The electric slide rail 17 is arranged on the bottom surface of the drying box 1 and is located below the discharge port 102. The electric push rod 18 is arranged in the electric slide rail 17. The upper end of the electric push rod 18 can push the particle board in the material flap 6 to move horizontally.

[0031] like Figure 1 As shown, it also includes a discharge plate 19 and a spring piece 20. The discharge plate 19 is fixed to the side of the drying box 1, specifically below the discharge port 102. The end face of the discharge plate 19 is provided with a spring piece 20. When the electric push rod 18 pushes the dried particle board out of the discharge port 102, the particle board will fall freely from a horizontal state to the inclined discharge plate 19. The spring piece 20 is provided to buffer and receive the particle board. The spring piece 20 can be made of a bent metal sheet to protect the particle board.

[0032] like Figure 1 and Figure 8 As shown, it also includes a second fan 21, a recycling box 22 and a dust box 23. The second fan 21 is connected to the other end of the drying box 1. A recycling box 22 is provided at the bottom of the second fan 21. The dust box 23 is slidably connected to the bottom of the recycling box 22. The second fan 21 is a pressure-balancing outlet fan. A screen is provided on the inner side of the second fan 21. The screen is used to block and screen wood chips stuck on the surface of the particle board. The wood chips are blocked by the screen and fall into the recycling box 22 below. A pull-out dust box 23 is provided at the bottom of the recycling box 22 to facilitate the staff to clean up the wood chips immediately.

[0033] like Figure 1As shown, it also includes a heat collecting box 24 and a constant pressure pipe 25. The heat collecting box 24 is arranged at the bottom of the drying box 1. The first fan 5 is connected to the right side of the drying box 1 through the constant pressure pipe 25, and the second fan 21 is connected to the left side of the drying box 1 through the constant pressure pipe 25, thereby forming a circulation path of the drying box 1, the second fan 21, the heat collecting box 24, and the first fan 5. The heat collecting box 24 is made of honeycomb polymer hygroscopic material. The first fan 5 introduces hot air into the drying box 1 to dry the particle board in the drying box 1. The second fan 21 sucks in the hot air with a higher water content and guides it to the heat collecting box 24 for drying. The dry air in the heat collecting box 24 enters the first fan 5 again, thereby forming a cycle, reducing the water content of the air while reducing heat loss, thereby improving the drying efficiency of the particle board.

[0034] Working principle: Place the particleboard to be dried on the feed belt 10, then turn on the feed belt 10 and the endless conveyor 2. The particleboard is guided to the feed plate 11 by the feed belt 10. During this period, the particleboard contacts and pushes the left end of the wedge contact plate 12, causing the wedge contact plate 12 to slide forward. When the wedge contact plate 12 touches the sensor plate 13, the sensor plate 13 controls the servo motor 14 to start through an electrical signal. The servo motor 14 drives the feed roller 15 to rotate. The retractable rubber contact 16 at the end of the feed roller 15 pushes the particleboard on the feed plate 11 backward through friction. The particleboard enters the drying box 1 from the feed port 101. When entering the drying box 1, the particleboard contacts the guide plate 72. The contact surface of the limit plate 71 is an inclined surface, which pushes the limit plate 71 outward, swinging the upper part of the limit roller 7 outward, compressing the torsion spring, so that the limit roller 7 fixes the particleboard at the material flap 6. The endless conveyor belt 2 drives the material plate 4 to rotate counterclockwise through the chain 3. During this period, the gear 8 at the front and rear ends of the rotating shaft of the material flap 6 can mesh with the rack 9 on the inner side of the drying box 1. Since the length of the rack 9 is half the circumference of the gear 8, the material flap 6 It can rotate 180 degrees, and the first fan 5 can dry the rotating particle board. Compared with the traditional fixed dryer, this device can circulate the particle board and at the same time flip the particle board. Combined with the drying treatment of the particle board by the first fan 5, the drying effect of the particle board is improved. When the particle board moves to the left side of the drying box 1, the electric slide 17 drives the electric push rod 18 to move forward. The upper end of the electric push rod 18 will push the particle board located in the material flap 6 to move forward and be discharged through the discharge port 102. The dried particle board will be discharged through the discharge port. When the plate 19 is led out and the particleboard is completely separated from the limiting roller 7, the torsion spring rebounds, driving the limiting roller 7 to swing inward relative to reset, thereby pulling the limiting plate 71 to slide inward, and at the same time driving the guide plate 72 to move and reset. The first fan 5 introduces hot air into the drying box 1 to dry the particleboard in the drying box 1. The second fan 21 sucks in the hot air with a higher water content and guides it to the heat collecting box 24 for drying. The dry air in the heat collecting box 24 enters the first fan 5 again, thereby forming a cycle, reducing the water content of the air while reducing heat loss, thereby improving the drying efficiency of the particleboard.

[0035] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
