Description

Technical Field

[0001] This utility model belongs to the field of wood-plastic pelleting technology, specifically relating to a long-distance spring lifting device for wood-plastic pelleting. Background Technology

[0002] Wood-plastic composite injection molding granules are a new type of composite material. They are made by mixing thermoplastics with plant fibers such as wood flour, rice husks, and bamboo powder to create new wood-based materials, followed by blending and granulation. Primarily suitable for injection molding processes, they serve as raw materials for various injection-grade wood-plastic products.

[0003] Current equipment for processing wood-plastic composite materials is relatively large, with the feeding port located at a high position. This requires conveying the wood-plastic composite material from bottom to top. However, current lifting equipment uses spiral blades for transportation, which involves long strokes, resulting in high maintenance costs and energy consumption. Furthermore, it is necessary to prevent material blockage at the feeding port and material adhesion to the box wall during material transportation. Therefore, a long-distance spring lifting device for wood-plastic pelleting is proposed. Summary of the Invention

[0004] This utility model provides a long-distance spring lifting device for wood-plastic pelleting. Its purpose is to solve the problems of current lifting devices that use spiral blades for transportation, which have long strokes, high maintenance costs, high energy consumption, and the need to prevent material from clogging at the inlet and sticking to the box wall during material transportation.

[0005] This utility model embodiment provides a long-distance spring-loaded material lifting device for wood-plastic pelleting, including a feeding box, a feeding pipe installed on one side of the feeding box, a motor installed at the other end of the feeding pipe, a discharge pipe installed near the motor, several support legs installed at the bottom of the feeding pipe, a lifting spring fixedly connected to the output end of the motor, a spiral blade fixedly connected to the other end of the lifting spring, the spiral blade being rotatably connected to the lower part of the feeding pipe, and an anti-accumulation component provided in the feeding box, which includes a tapping component.

[0006] Furthermore, both ends of the spiral blade are connected to rod-shaped rotating mounting seats installed inside the feeding pipe.

[0007] By adopting the above technical solution, the rod-shaped rotating mounting base allows the spiral blade to rotate without excessively hindering the movement of materials.

[0008] Furthermore, the anti-accumulation assembly includes a central shell fixedly installed in the feeding box. A second spiral blade is rotatably connected to the bottom of the central shell. One end of a transmission rod is fixedly connected to the left side of the second spiral blade. The other end of the transmission rod is fixedly connected to the output end of a second motor installed on the feeding box. A top rod is installed on the rod part of the second spiral blade. The bottom of two support rods is fixedly connected to the inner wall of the feeding box. A support ring is fixedly connected to the top of the two support rods. A moving rod is slidably connected in the support ring. A transmission platform is fixedly connected to the top of the moving rod. A contact platform is fixedly connected to the bottom of the transmission platform.

[0009] By adopting the above technical solution, the second motor is started, and the output end of the second motor drives the rotation of the transmission rod and the second spiral blade, which can push the material fed into the collection shell to prevent it from accumulating at the bottom of the collection shell. During the rotation of the second spiral blade, the top rod will rotate together, and the top rod will intermittently contact the contact table, which can make the contact table move up and down. This can drive the work of the beater component and at the same time clear the blockage, reducing the probability of material accumulation.

[0010] Furthermore, the bottom of the contact platform is arc-shaped, the push rod is located below the contact platform, and one end of the push rod extends beyond the blade edge of the second helical blade.

[0011] By adopting the above technical solution, the arc-shaped contact platform facilitates smoother contact between the push rod and the contact platform. The push rod extends beyond the edge of the blade, which prevents the contact platform from contacting the second spiral blade. There is a gap between the contact platform and the blade of the second spiral blade to prevent mutual interference.

[0012] Furthermore, the end of the spiral blade two that is away from the motor two is connected to a rod-shaped rotating mounting base two installed on the bottom wall of the central housing.

[0013] By adopting the above technical solution, the second rod-shaped rotating mounting base supports one end of the second spiral blade, ensuring the operation of the second spiral blade.

[0014] Furthermore, the tapping assembly includes several annularly distributed support seats mounted on a support ring. A swing rod is rotatably connected to the support seat. One end of the swing rod has a waist hole, and the other end of the swing rod is fixedly connected to a rubber tapping block. Several fixed seats corresponding to the positions of the swing rod are fixedly connected to the top of the transmission platform, and a transmission column is fixedly connected in the fixed seat.

[0015] By adopting the above technical solution, when the material is conveyed by the tapping assembly, the top rod drives the moving rod to move up and down. This allows the transmission table to drive the swing rod to swing up and down, thereby allowing the rubber tapping block to move and tap the wall of the collection shell, shaking off the material left on the collection shell through tapping vibration. This eliminates the need for manual handling and reduces labor intensity.

[0016] Furthermore, the transmission column passes through the waist hole.

[0017] By adopting the above technical solution, the cooperation between the transmission column and the waist hole allows the transmission column to have sufficient movement space to cooperate with the swing when it drives the swing rod to move.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention utilizes a second motor to drive the rotation of a transmission rod and a second spiral blade, which pushes the material fed into the collection shell to prevent it from accumulating at the bottom of the collection shell. During the rotation of the second spiral blade, the contact platform can be moved up and down in conjunction with the top rod, thus driving the work of the beater component and simultaneously clearing the blockage, reducing the probability of material accumulation. The material left on the collection shell is shaken off by the beating vibration, eliminating the need for manual handling and reducing labor intensity.

The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Reference Figures 1-5 This utility model embodiment proposes a long-distance spring lifting device for wood-plastic pelleting, including a feeding box 1, a feeding pipe 2 installed on one side of the feeding box 1, a motor 3 installed at the other end of the feeding pipe 2, a discharge pipe 4 installed near the motor 3 on the feeding pipe 2, several support legs 5 installed at the bottom of the feeding pipe 2, one end of a lifting spring 6 fixedly connected to the output end of the motor 3, and a spiral blade 7 fixedly connected to the other end of the lifting spring 6. The spiral blade 7 is rotatably connected to the lower part of the feeding pipe 2. An anti-accumulation component is provided in the feeding box 1, and a tapping component is installed in the anti-accumulation component.

[0030] The two ends of the spiral blade 7 are connected to rod-shaped rotating mounting seats installed inside the feeding pipe 2. The rod-shaped rotating mounting seats allow the spiral blade 7 to rotate without excessively hindering the movement of materials.

[0031] The anti-accumulation assembly includes a central housing 81 fixedly installed in the feeding box 1. A second spiral blade 89 is rotatably connected to the bottom of the central housing 81. One end of a transmission rod 88 is fixedly connected to the left side of the second spiral blade 89. The other end of the transmission rod 88 is fixedly connected to the output end of a second motor 87 installed on the feeding box 1. A top rod 810 is installed on the rod of the second spiral blade 89. The bottoms of two support rods 82 are fixedly connected to the inner wall of the feeding box 1. A support ring 83 is fixedly connected to the top of the two support rods 82. A movable rod 84 is slidably connected in the support ring 83. The top of the movable rod 84... A transmission platform 85 is fixedly connected to the main body, and a contact platform 86 is fixedly connected to the bottom of the transmission platform 85. It is started by a motor 87. The output end of the motor 87 drives the transmission rod 88 and the spiral blade 89 to rotate, which can push the material fed into the collection shell 81 to prevent it from accumulating at the bottom of the collection shell 81. During the rotation of the spiral blade 89, the push rod 810 will rotate together. The push rod 810 intermittently contacts the contact platform 86, which allows the contact platform 86 to move up and down. This drives the work of the tapping component and can also clear the blockage and reduce the probability of material accumulation.

[0032] The bottom of the contact platform 86 is arc-shaped, and the push rod 810 is located below the contact platform 86. One end of the push rod 810 extends beyond the blade edge of the second spiral blade 89. The arc shape of the contact platform 86 facilitates smoother contact between the push rod 810 and the contact platform 86. The fact that the push rod 810 extends beyond the blade edge prevents the contact platform 86 from contacting the second spiral blade 89. There is a gap between the contact platform 86 and the blade of the second spiral blade 89 to prevent mutual interference.

[0033] The end of the spiral blade 89 furthest from the motor 87 is connected to a rod-shaped rotating mounting base 2 installed on the bottom wall of the central housing 81. The rod-shaped rotating mounting base 2 supports one end of the spiral blade 89 to ensure the operation of the spiral blade 89.

[0034] The tapping assembly includes several annularly distributed support seats 95 mounted on a support ring 83. A swing rod 92 is rotatably connected to the support seat 95. One end of the swing rod 92 has a waist hole 93, and the other end of the swing rod 92 is fixedly connected to a rubber tapping block 96. Several fixed seats 91 corresponding to the positions of the swing rod 92 are fixedly connected to the top of the transmission table 85. A transmission column 94 is fixedly connected to the fixed seat 91. When the tapping assembly is used to transport materials, the top rod 810 drives the moving rod 84 to move up and down. This allows the transmission table 85 to drive the swing rod 92 to swing up and down, thereby allowing the rubber tapping block 96 to move and tap the wall of the collection shell 81. The material left on the collection shell 81 is shaken off by the tapping vibration, eliminating the need for manual handling and reducing labor intensity.

[0035] The transmission column 94 passes through the waist hole 93. The cooperation between the transmission column 94 and the waist hole 93 allows the transmission column 94 to have enough room to move and swing when it drives the swing rod 92.

[0036] The specific implementation method is as follows: When in use, after the wood-plastic material is fed into the feeding box 1, it enters the collection shell 81. At this time, the motor 3 and the motor 87 are started. The output end of the motor 87 drives the transmission rod 88 and the spiral blade 89 to rotate, which can push the material fed into the collection shell 81 to the spiral blade 7. Then, through the operation of the spiral blade 7 and the lifting spring 6, it is transported to a higher position. The lifting spring 6 has a simple structure, low energy consumption and low maintenance cost. Then it is discharged from the discharge pipe 4 into the pelleting equipment. During the rotation of the spiral blade 89, the top rod 810 will rotate together. The top rod 810 drives the moving rod 84 to move up and down. This allows the transmission table 85 to drive the swing rod 92 to swing up and down, which in turn allows the rubber beating block 96 to move and beat the wall of the collection shell 81, shaking off the material left on the collection shell 81. No manual processing is required, reducing labor intensity.
