Technical Field

[0001] This invention relates to the technical field of pearlescent pigment production, specifically to a unit for recycling calcined pearlescent pigment trays. Background Technology

[0002] Pearl pigment calcination tray recycling device is a device used to collect and reuse used trays. It is commonly used in industrial and logistics environments to minimize resource waste and improve the efficiency of material management.

[0003] Patent publication number CN219296318U relates to a novel unit for recycling calcined pearlescent pigment trays. It includes a conveying assembly, a receiving assembly, and a collecting assembly. The conveying assembly is located between the roller kiln and the unloading device. Lifting cylinders are located on both sides of the conveying assembly to lift it upwards. Several parallel-arranged guide rollers are located on the upper side of the conveying assembly, and a receiving baffle is located on the lower side. Both the receiving and collecting assemblies are located below the conveying assembly. The collecting assembly is movably positioned between the unloading device and the receiving assembly. The collecting assembly has a collecting hopper, and a guide plate is fixed to the collecting assembly, blocking the front opening of the collecting hopper. The receiving plate of the receiving assembly is vertically raised and lowered in the middle groove of the guide plate.

[0004] In the aforementioned patent, empty calcination trays can be automatically received and stacked through a guiding component, a receiving component, and a collecting component, achieving fully automatic collection of calcination trays and improving the efficiency of material management. However, in actual use, the empty trays slide down to the collecting component under their own gravity. If foreign objects block the slide, it will affect the operation of the device, thus affecting the recycling process, increasing the workload of staff and maintenance costs. Therefore, a unit with an automatic collecting function for recycling pearlescent pigment calcination trays is designed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a unit for recycling calcined material trays of pearlescent pigments, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a unit for recycling calcined pearlescent pigment trays, comprising a worktable and a roller conveyor, and further comprising a tray receiving device and a straightening device; wherein, an mounting plate is fixedly installed below the worktable, and a motor is fixedly installed above the mounting plate; wherein, the tray receiving device comprises a push rod, a fixed plate, a push plate, a tray receiving frame, a slider, a longitudinal tray, a fixed rod, and a stop block, the tray moves to the surface of the fixed plate under the action of the roller conveyor, and then the motor is started, the output end of the motor moves upward, driving the push rod to move upward, the push rod being fixedly installed at the output end of the motor, and the fixed plate... The push plate is fixedly installed on the surface of the roller conveyor, and the pusher is fixedly installed above the pusher rod. The surface of the worktable has a slot, and the receiving tray is snapped into the inside of the slot. The surface of the receiving tray has a first sliding groove, and the slider is slidably installed inside the first sliding groove. The longitudinal receiving tray is fixedly installed above the slider, and the surface of the slider has a second sliding groove. The fixing rod is fixedly inserted through the inner and outer walls of the second sliding groove. The stop block is rotatably installed on the surface of the fixing rod. The stop block reverses and is limited by the inner wall of the first sliding groove, and supports the material tray, realizing the recycling of the material tray, reducing the workload of the workers and the subsequent maintenance costs.

[0007] According to the above technical solution, a spring is provided between the stop block and the fixed rod. The surface of the stop block is opened into an arc surface. The rotation of the stop block can be further reset under the action of the spring, so as to avoid the stop block reset being affected by foreign objects and improve the recycling efficiency.

[0008] According to the above technical solution, the straightening device includes a connecting rod, an L-shaped rod, a receiving platform, a clamping plate, and a connecting rod. The upward movement of the push rod causes the connecting rod to move upward, which in turn causes the L-shaped rod to move upward, and the upward movement of the L-shaped rod causes the connecting rod to move. The connecting rod is fixedly installed on the surface of the push rod. A three-slide groove is provided on the surface of the worktable, and the L-shaped rod is slidably installed inside the three-slide groove. The receiving platform is fixedly installed above the worktable, and the clamping plate is slidably installed above the receiving platform. The connecting rod is hinged to the surface of the L-shaped rod, with the end of the connecting rod away from the L-shaped rod hinged to the clamping plate. The end of the connecting rod away from the push rod is fixedly connected to the L-shaped rod. The movement of the connecting rod causes the clamping plate to move, clamping the material on the roller conveyor surface to achieve a straightening effect on the material tray, preventing the tilted material tray from entering the surface of the push plate and colliding with the receiving frame during recycling, thus improving recycling efficiency and reducing subsequent maintenance costs.

[0009] According to the above technical solution, a telescopic spring rod is fixedly installed on the surface of the clamping plate, and a pressure plate is fixedly installed on the free end of the telescopic spring rod. The movement of the clamping plate drives the telescopic spring rod to move, and the movement of the telescopic spring rod drives the pressure plate to move. The pressure plate moves and can generate a rebound under the action of the telescopic spring rod, which can effectively straighten the material trays of different sizes and improve the efficiency and applicability of recycling.

[0010] According to the above technical solution, it also includes an adjustment device and a limiting device. The adjustment device includes a receiving rod, a receiving block, a sliding plate, a triangular block, and a limiting rod. During the process of the pressure plate moving and contacting the material tray, it will drive the receiving rod to move. The moving receiving rod will contact and drive the receiving block to move. The moving receiving block will drive the slider to move. The receiving rod is fixedly installed on the surface of the pressure plate. The receiving block is fixedly installed on the surface of the slider. The surface of the receiving tray frame is provided with a four-slide groove. The sliding plate is slidably installed inside the four-slide groove. The triangular block is slidably installed inside the four-slide groove. The surface of the receiving block is provided with a limiting groove. The limiting rod is slidably installed inside the four-slide groove. The sliding plate and the triangular block are fixedly connected by a spring. The longitudinal movement of the receiving tray can realize the recycling of material trays of different sizes, avoiding the inability of the receiving tray frame to effectively recycle due to the material tray size being too large or too small, thereby improving the recycling efficiency.

[0011] According to the above technical solution, a telescopic spring rod 2 is fixedly installed on the inner wall of the slide groove 4. The free end of the telescopic spring rod 2 is fixedly connected to the limiting rod. A sliding rod is fixedly installed on the surface of the limiting rod. The movement of the limiting rod drives the sliding rod to move. The sliding rod can effectively prevent foreign objects from falling into the interior of the slide groove 4 and causing blockage, thereby reducing subsequent maintenance costs.

[0012] According to the above technical solution, the limiting device includes a transverse receiving plate, a movable plate, a stop bar, a baffle, and a pressure bar. The material tray moves upward to contact and press the pressure bar on the surface of the transverse receiving plate. The pressure bar moves to contact and drive the movable plate to move. The movable plate moves to drive the stop bar to move. The transverse receiving plate is fixedly installed on the surface of the receiving plate frame. A five-slide groove is opened on the surface of the transverse receiving plate. The movable plate is slidably connected inside the five-slide groove. The stop bar is fixedly installed on the surface of the movable plate. The baffle is slidably installed on the inner wall of the five-slide groove. The pressure bar is slidably installed on the inner wall of the five-slide groove. A limiting groove is opened at the end of the baffle near the stop bar. The baffle moves upward and is again limited by the stop bar, so that the baffle can fully contact and fix the material tray, avoiding shaking and collision of the material tray during transportation to the receiving plate frame, and reducing subsequent maintenance costs.

[0013] According to the above technical solution, a second spring is provided between the moving plate and the slide chute, the surface of the pressure rod is cut into a bevel, and a third spring is provided between the pressure rod and the slide chute. The second spring can effectively improve the contact effect between the baffle and the material tray, further avoid damage caused by the material trays colliding with each other due to shaking, improve the recycling efficiency, and reduce subsequent maintenance costs.

[0014] This invention provides a unit for recycling calcined material trays of pearlescent pigments. It has the following beneficial effects: (1) In this unit, the receiving frame is attached to the top of the worktable through the slot. The material tray enters the surface of the fixed plate and the push plate through the roller conveyor. Then the motor starts and pushes the material tray into the inside of the receiving frame through the push rod and the push plate. The material tray moves upward to contact and squeeze the stop block and generate rotation. After the stop block rotates, it resets under the action of the material tray's gravity and supports the material tray, realizing the recycling of the material tray and reducing subsequent maintenance costs. At the same time, the spring can further drive the stop block to reset and guide the subsequent material tray into the inside of the receiving frame, which can effectively improve the recycling efficiency.

[0015] (2) In this unit, the push rod moves upward and drives the connecting rod and clamping plate to move through the connecting rod and L-shaped rod. The movement of the clamping plate can effectively straighten the material tray on the roller surface, preventing the tilted material tray from entering the surface of the push plate and causing it to collide with the receiving frame during the recycling process, thereby improving the recycling efficiency and reducing subsequent maintenance costs. At the same time, the movement of the clamping plate drives the telescopic spring rod and the pressure plate to move. The movement of the pressure plate will cause the material tray to rebound when it contacts the material tray, which can effectively straighten material trays of different sizes, improve recycling efficiency and applicability.

[0016] (3) In this unit, the pressure plate moves by the receiving rod and the receiving block, which drives the slider and the longitudinal receiving plate to move. The longitudinal receiving plate can effectively realize the recycling of material trays of different sizes, avoiding the material trays being too large or too small, which would prevent the receiving plate from being unable to recycle effectively, thus improving the recycling efficiency. At the same time, the receiving block moves by the sliding plate and the triangular block to fix the slider, avoiding the displacement during recycling. The moving limit rod can release the limit on the slider, so that its subsequent use is not affected. In addition, the sliding rod can effectively prevent foreign objects from falling into the interior of the slide groove and causing blockage, thus reducing the subsequent maintenance cost. (4) In this unit, the material tray contacts and squeezes the pressure rod during recycling. The pressure rod moves by the moving plate and the stop block to release the limit on the baffle. After the limit is released, the baffle moves upward under the action of the material tray and is limited by the stop block again, so that the baffle can fully contact and fix the material tray, avoiding the material tray from shaking and colliding during the transportation of the receiving plate. At the same time, the spring spring can effectively improve the contact effect between the baffle and the material tray, further preventing the material tray from shaking and colliding.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-5One embodiment of the present invention is: a unit for recycling calcined pearlescent pigment trays, comprising a workbench 1 and a roller conveyor 2, and further comprising a tray receiving device and a straightening device; wherein, a mounting plate 7 is fixedly installed below the workbench 1, and a motor is fixedly installed above the mounting plate 7; wherein, the tray receiving device comprises a push rod 31, a fixed plate 32, a push plate 33, a tray receiving frame 34, a slider 35, a longitudinal tray 36, a fixed rod 37, and a stop block 38, the tray moves to the surface of the fixed plate 32 under the action of the roller conveyor 2, and then the motor is started, the output end of the motor moves upward, driving the push rod 31 to move upward, the push rod 31 is fixedly installed at the output end of the motor, and the fixed plate 32... The roller conveyor 2 is fixedly installed on the surface of the roller conveyor 2. The push plate 33 is fixedly installed above the push rod 31. The surface of the worktable 1 is provided with a slot. The receiving tray 34 is snapped into the slot. The surface of the receiving tray 34 is provided with a first sliding groove. The slider 35 is slidably installed inside the first sliding groove. The longitudinal receiving tray 36 is fixedly installed above the slider 35. The surface of the slider 35 is provided with a second sliding groove. The fixing rod 37 is fixedly installed through the inner and outer walls of the second sliding groove. The stop block 38 is rotatably installed on the surface of the fixing rod 37. The stop block 38 is reversed and limited by the inner wall of the first sliding groove, and supports the material tray, realizing the recycling of the material tray, reducing the workload of the workers and the subsequent maintenance costs.

[0021] A spring is provided between the stop block 38 and the fixed rod 37. The surface of the stop block 38 is curved. The rotation of the stop block 38 can be further reset under the action of the spring, so as to avoid the stop block 38 being affected by foreign objects and improve the recycling efficiency.

[0022] The straightening device includes a connecting rod 41, an L-shaped rod 42, a receiving platform 43, a clamping plate 44, and a connecting rod 45. The upward movement of the push rod 31 causes the connecting rod 41 to move upward, which in turn causes the L-shaped rod 42 to move upward, and the upward movement of the L-shaped rod 42 causes the connecting rod 45 to move. The connecting rod 41 is fixedly installed on the surface of the push rod 31. A three-slide groove is provided on the surface of the worktable 1, and the L-shaped rod 42 is slidably installed inside the three-slide groove. The receiving platform 43 is fixedly installed above the worktable 1, and the clamping plate 44 is slidably installed on the receiving platform. Above platform 43, connecting rod 45 is hinged to the surface of L-shaped rod 42. The end of connecting rod 45 away from L-shaped rod 42 is hinged to clamping plate 44. The end of connecting rod 41 away from push rod 31 is fixedly connected to L-shaped rod 42. The movement of connecting rod 45 drives clamping plate 44 to move. The movement of clamping plate 44 clamps the material on the surface of roller conveyor 2, achieving the effect of straightening the material tray, preventing the tilted material tray from entering the surface of push plate 33, which would cause collision with receiving frame 34 during recycling, thus improving recycling efficiency and reducing subsequent maintenance costs.

[0023] A telescopic spring rod 46 is fixedly installed on the surface of the clamping plate 44. A pressure plate 47 is fixedly installed on the free end of the telescopic spring rod 46. The movement of the clamping plate 44 drives the telescopic spring rod 46 to move, which in turn drives the pressure plate 47 to move. The pressure plate 47 moves and can rebound under the action of the telescopic spring rod 46, which can effectively straighten material trays of different sizes and improve the efficiency and applicability of recycling.

[0024] In this embodiment, the receiving frame 34 is engaged with the slot on the surface of the worktable 1. Then, the roller conveyor 2 is started, and the material tray moves to the surface of the fixed plate 32 under the action of the roller conveyor 2. Then, the motor is started, and the output end of the motor moves upward, driving the push rod 31 to move upward. The push rod 31 moves upward, driving the push plate 33 to move upward. The push plate 33 moves upward, driving the material tray to move upward. The material tray moves upward and contacts and squeezes the stop block 38 to rotate. The rotation of the stop block 38 guides the material tray into the interior of the receiving frame 34. Then, the push rod 31 and the push plate 33 reset, causing the material tray to move downward and contact and squeeze the stop block 38 to reverse. The stop block 38 reverses and is limited by the inner wall of the slide chute, supporting the material tray. This realizes the recycling of the material tray, reduces the workload of the workers and the subsequent maintenance costs. At the same time, the rotation of the stop block 38 can be further reset under the action of the spring, avoiding the impact of foreign objects on the reset of the stop block 38, and improving the recycling efficiency.

[0025] The upward movement of push rod 31 drives the connecting rod 41 to move upward, which in turn drives the L-shaped rod 42 to move upward. The L-shaped rod 42 then drives the connecting rod 45 to move, which in turn drives the clamping plate 44 to move. The clamping plate 44 clamps the material on the surface of the roller conveyor 2, thus straightening the material tray and preventing the tilted tray from entering the surface of push plate 33, which would cause it to collide with the receiving frame 34 during recycling. This improves recycling efficiency and reduces subsequent maintenance costs. At the same time, the movement of clamping plate 44 drives the telescopic spring rod 46 to move, which in turn drives the pressure plate 47 to move. The pressure plate 47 moves and, under the action of the telescopic spring rod 46, can rebound, effectively straightening material trays of different sizes and improving recycling efficiency and applicability.

[0026] Please see Figure 1-7Based on the above embodiments, another embodiment of the present invention further includes an adjustment device and a limiting device. The adjustment device includes a receiving rod 51, a receiving block 52, a sliding plate 53, a triangular block 54, and a limiting rod 55. During the movement of the pressure plate 47 in contact with the material tray, it drives the receiving rod 51 to move. The moving receiving rod 51 contacts and drives the receiving block 52 to move. The moving receiving block 52 drives the slider 35 to move. The receiving rod 51 is fixedly installed on the surface of the pressure plate 47, and the receiving block 52 is fixedly installed on the surface of the slider 35. The surface of the receiving tray frame 34 is provided with a sliding groove four. The sliding plate 53 is slidably installed inside the sliding groove four, and the triangular block 54 is slidably installed inside the sliding groove four. The surface of the receiving block 52 is provided with a limiting groove one, and the limiting rod 55 is slidably installed inside the sliding groove four. The sliding plate 53 and the triangular block 54 are fixedly connected by a spring one. The longitudinal movement of the receiving tray 36 can realize the recycling of material trays of different sizes, avoiding the inability of the receiving tray frame 34 to effectively recycle due to the material tray size being too large or too small, thereby improving the recycling efficiency.

[0027] The inner wall of the slide groove four is fixedly installed with a telescopic spring rod two 56. The free end of the telescopic spring rod two 56 is fixedly connected to the limiting rod 55. A slide rod 57 is fixedly installed on the surface of the limiting rod 55. The movement of the limiting rod 55 drives the slide rod 57 to move. The slide rod 57 can effectively prevent foreign objects from falling into the interior of the slide groove four and causing blockage, thus reducing subsequent maintenance costs.

[0028] The limiting device includes a transverse receiving plate 61, a movable plate 62, a stop bar 63, a baffle 64, and a pressure bar 65. The material tray moves upward to contact and press the pressure bar 65 on the surface of the transverse receiving plate 61. The pressure bar 65 moves to contact and drive the movable plate 62 to move. The movable plate 62 moves to drive the stop bar 63 to move. The transverse receiving plate 61 is fixedly installed on the surface of the receiving plate frame 34. A five-slide groove is opened on the surface of the transverse receiving plate 61. The movable plate 62 is slidably connected to the inside of the five-slide groove. The stop bar 63 is fixedly installed on the surface of the movable plate 62. The baffle 64 is slidably installed on the inner wall of the five-slide groove. The pressure bar 65 is slidably installed on the inner wall of the five-slide groove. A limiting groove 2 is opened at the end of the baffle 64 near the stop bar 63. The baffle 64 moves upward and is again limited by the stop bar 63, so that the baffle 64 can fully contact and fix the material tray, avoiding shaking and collision of the material tray during transportation to the receiving plate frame 34, and reducing subsequent maintenance costs.

[0029] A second spring is installed between the moving plate 62 and the slide 5. The surface of the pressure rod 65 is cut into a bevel. A third spring is installed between the pressure rod 65 and the slide 5. The second spring can effectively improve the contact effect between the baffle 64 and the material tray, further avoid damage caused by the material trays colliding with each other due to shaking, improve the recycling efficiency, and reduce subsequent maintenance costs.

[0030] In this embodiment, during operation, the pressure plate 47 moves and contacts the material tray, which in turn drives the receiving rod 51 to move. The receiving rod 51 then contacts and drives the receiving block 52 to move. The moving receiving block 52 drives the slider 35 to move, which in turn drives the longitudinal receiving plate 36 to move. The movement of the longitudinal receiving plate 36 enables the recycling of material trays of different sizes, avoiding the inability of the receiving frame 34 to effectively recycle material trays that are too large or too small, thus improving recycling efficiency. At the same time, the moving receiving block 52 contacts and squeezes the triangular block 54, which moves and is then pressed by the spring. Under the action of the first, the resetting mechanism is used to limit the receiving block 52 through the limiting groove, so as to realize the recycling of the same batch of material trays and avoid the longitudinal receiving tray 36 from shifting during the recycling process. At the same time, the moving limiting rod 55 can release the limiting of the sliding plate 53. After the sliding plate 53 is released from the limiting, the triangular block 54 can release the limiting of the receiving block 52, so as to avoid affecting the recycling of subsequent material trays. At the same time, the movement of the limiting rod 55 drives the sliding rod 57 to move. The sliding rod 57 can effectively prevent foreign objects from falling into the interior of the sliding groove and causing blockage, thus reducing subsequent maintenance costs.

[0031] The material tray moves upward to contact and press the pressure rod 65 on the surface of the transverse receiving tray 61. The pressure rod 65 moves to contact and drive the moving plate 62 to move. The moving plate 62 drives the stop rod 63 to move. The stop rod 63 moves to disengage from the limiting groove two on the surface of the baffle 64 and releases the limit. After the limit is released, the baffle 64 moves upward under the action of the material tray. The baffle 64 moves upward and is limited again by the stop rod 63, so that the baffle 64 can fully contact and fix the material tray, avoiding the material tray from shaking and colliding during the transportation of the receiving tray frame 34, reducing subsequent maintenance costs. At the same time, the second spring can effectively improve the contact effect between the baffle 64 and the material tray, further avoiding damage caused by the collision between the material trays due to shaking, improving the recycling efficiency and reducing subsequent maintenance costs.
