Description

Technical Field

[0001] This utility model relates to the field of granulator technology, and more specifically, to a feeding device for a recycled foam granulator. Background Technology

[0002] Currently, the plastic granulation extruders used are all integrated equipment. Raw materials such as plastics are transported from the hopper to the forced feeder, which is equipped with a screw. Finally, the material is extruded from the extrusion port. Because the raw material is heated inside the screw for a long time, it will result in low transparency of the raw material, increased waste, and unsuitability for production.

[0003] To address the aforementioned issues, patent CN205889837U discloses a three-stage plastic granulation extruder, relating to the field of plastic extruders. A motor is mounted on one side of a forced feeder, and a first-stage screw is installed inside the forced feeder. One end of the first-stage screw has a first extrusion port, below which is a hopper positioned on a second-stage screw. One end of the second-stage screw has a second extrusion port, which connects to one end of the third-stage screw. The other end of the third-stage screw has a third extrusion port, below which is a cooling device. Its structure is rationally designed, simple to operate, and convenient to use. By dividing the original heated screw into three parts—a first-stage granulation zone, a second-stage granulation zone, and a third-stage granulation zone—it solves the problem of long material time inside the high-heat screw. Shorter material time inside the screw improves material transparency. The three-stage operation not only improves production efficiency but also allows for gradual reduction of resistance.

[0004] However, it still has some shortcomings in actual use. For example, the traditional feeder can only feed one type of raw material. The cumbersome action of frequently changing the feeder not only wastes manpower and time and reduces production efficiency, but also the main unit may experience a series of problems due to excessive feeding, raw material foaming, and uneven crushing of raw materials. In order to solve the above problems, we propose a feeding device for a recycled foam granulator. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a feeding device for a recycled foam granulator, which solves the problem that the traditional feeder feeding device can only meet the feeding of one type of raw material, and the cumbersome action of frequently changing the feeder not only wastes manpower and time and reduces production efficiency, but also the main machine may have a series of problems caused by excessive feeding, foaming of raw materials, and uneven crushing of raw materials.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a feeding device for a recycled foam granulator, comprising a main screw barrel, quick-assembly and disassembly components on both sides of the main screw barrel, a first screw barrel on one side of the main screw barrel, a first feed bin fixedly installed on the upper surface of the first screw barrel, a first motor fixedly installed at one end of the first screw barrel, a second screw barrel on the other side of the main screw barrel, a second feed bin fixedly installed on the upper outer surface of the second screw barrel, and a second motor fixedly installed at one end of the second screw barrel.

[0007] The quick-assembly assembly includes a connecting pipe with two connecting columns slidably installed on the inner walls of both sides. An L-shaped connecting rod is fixedly installed at one end of each connecting column. A positive and negative threaded rod is threaded to the upper inner wall of the L-shaped connecting rod. A circular valve is fixedly sleeved on the middle of the outer surface of the positive and negative threaded rod. An arc-shaped clamping plate is symmetrically fixedly installed at one end of each connecting column, and a silicone sealing gasket is fixedly installed on the inner arc surface of the arc-shaped clamping plate.

[0008] The arc-shaped clamping plate and the silicone sealing gasket both slide on the inner wall of the connecting pipe, and the circular valve slides on the upper inner surface of the connecting pipe.

[0009] The device includes two arc-shaped clamping plates and two silicone sealing gaskets, which are symmetrically arranged. One arc-shaped clamping plate and silicone sealing gasket has notches at both ends, and the other arc-shaped clamping plate and silicone sealing gasket slide on the outer wall of the notch, so that the two arc-shaped clamping plates and silicone sealing gaskets can engage and slide.

[0010] The first screw barrel has a diameter of 220cm and a length of 800cm, and the first feed bin is located 400cm away from the main screw barrel. The second screw barrel has a diameter of 170cm and a length of 900cm, and the second feed bin is located 500cm away from the main screw barrel.

[0011] The first and second screw barrels are both equipped with spiral blades inside, and the spiral blades inside the first screw barrel are fixedly connected to the output end of the first motor, while the spiral blades inside the second screw barrel are fixedly connected to the output end of the second motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a first and second screw drum. Crushed compressed foam or hot-melt foam is fed into a first feeding hopper 400cm from the main screw drum via a auger. The foam then enters the first screw drum, which has a diameter of 220cm and a length of 800cm. A spiral blade is installed inside the first screw drum. A first motor is activated to rotate the spiral blade and push the raw material into the main machine. On the other side, multiple mixed raw materials are fed into a second feeding hopper 500cm from the main machine. This foam then enters a second screw drum with a diameter of 170cm and a length of 900cm. A spiral blade is also installed inside the second screw drum. A second motor is activated to rotate the spiral blade and push the raw material into the main machine. This structure eliminates the cumbersome operation of traditional feeders that can only handle one type of raw material and require frequent changes to the feeder. Furthermore, the granulator no longer experiences problems such as excessive feeding, foaming of raw materials, or uneven crushing of raw materials. This significantly improves the production efficiency of the second feeding hopper.

[0014] This invention utilizes a quick-assembly and disassembly assembly, including a connecting pipe. First, the outer wall of one end of the corresponding first or second screw barrel is placed on the inner surface of the connecting pipe. Then, rotating the circular valve drives the positive and negative lead screws to rotate. The rotation of the lead screws causes the two L-shaped connecting rods threaded on their outer surfaces to move relative to each other, thereby causing the connecting column to slide on the inner wall of the connecting pipe. This, in turn, causes the two arc-shaped clamping plates to clamp relative to each other, resulting in two silicone sealing gaskets being clamped against the outer wall of the first or second screw barrel. Using this structure, by rotating the circular valve and causing the two arc-shaped clamping plates to move relative to each other, the installation and disassembly of the first or second screw barrel is facilitated, greatly improving the flexibility and practicality of the granulator.

Detailed Implementation

[0019] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0020] As attached Figure 1 To be continued Figure 2 This utility model provides a feeding device for a recycled foam granulator, including a main screw barrel 1, quick-release components 2 on both sides of the main screw barrel 1, a first screw barrel 3 on one side of the main screw barrel 1, a first feed bin 4 fixedly installed on the upper surface of the first screw barrel 3, a first motor 5 fixedly installed at one end of the first screw barrel 3, a second screw barrel 6 on the other side of the main screw barrel 1, a second feed bin 7 fixedly installed on the upper outer surface of the second screw barrel 6, and a second motor 8 fixedly installed at one end of the second screw barrel 6.

[0021] By setting up the first screw barrel 3 and the second screw barrel 6, the traditional feeder can only meet the needs of feeding one type of raw material, and the cumbersome operation of frequently changing the feeding device is changed. Moreover, the main unit of the granulator no longer has a series of problems caused by excessive feeding, raw material foaming, and uneven crushing of raw materials. To a certain extent, the production efficiency of the second feeding bin 7 is greatly improved.

[0022] The quick-assembly assembly 2 includes a connecting pipe 21. Two connecting posts 22 are slidably installed on the inner walls of both sides of the connecting pipe 21. An L-shaped connecting rod 23 is fixedly installed at one end of the two connecting posts 22. A positive and negative threaded rod 24 is threadedly connected to the upper inner wall of the L-shaped connecting rod 23. A circular valve 25 is fixedly sleeved on the middle of the outer surface of the positive and negative threaded rod 24. An arc-shaped clamping plate 26 is symmetrically fixedly installed at one end of each of the two connecting posts 22. A silicone sealing gasket 27 is fixedly installed on the inner arc surface of the arc-shaped clamping plate 26.

[0023] Among them, the arc-shaped clamping plate 26 and the silicone sealing gasket 27 both slide on the inner wall of the connecting pipe 21, and the circular valve 25 slides on the upper inner surface of the connecting pipe 21.

[0024] By rotating the circular valve 25, the two arc-shaped clamping plates 26 move relative to each other, which facilitates the installation and disassembly of the first screw barrel 3 or the second screw barrel 6, greatly improving the flexibility and practicality of the granulator.

[0025] Two arc-shaped clamping plates 26 and two silicone sealing pads 27 are provided. The two arc-shaped clamping plates 26 and two silicone sealing pads 27 are symmetrically arranged. One arc-shaped clamping plate 26 and one silicone sealing pad 27 have notches at both ends. The other arc-shaped clamping plate 26 and one silicone sealing pad 27 slide on the outer wall of the notch, so that the two arc-shaped clamping plates 26 and two silicone sealing pads 27 can engage and slide.

[0026] The first screw barrel 3 has a diameter of 220cm and a length of 800cm, and the first feed chamber 4 is located 400cm away from the main screw barrel 1. The second screw barrel 6 has a diameter of 170cm and a length of 900cm, and the second feed chamber 7 is located 500cm away from the main screw barrel 1.

[0027] The first screw barrel 3 and the second screw barrel 6 are both equipped with spiral blades inside. The spiral blades inside the first screw barrel 3 are fixedly connected to the output end of the first motor 5, and the spiral blades inside the second screw barrel 6 are fixedly connected to the output end of the second motor 8.

[0028] The working process of this utility model is as follows:

[0029] First, place the outer wall of one end of the corresponding first screw barrel 3 or second screw barrel 6 on the inner surface of the connecting pipe 21. Then, rotate the circular valve 25 to drive the positive and negative screw rods 24 to rotate. The rotation of the positive and negative screw rods 24 causes the two L-shaped connecting rods 23 connected by threads on their outer surfaces to move relative to each other, thereby causing the connecting column 22 to slide on the inner wall of the connecting pipe 21. This, in turn, causes the two arc-shaped clamping plates 26 to clamp relative to each other, so that the two silicone sealing gaskets 27 are clamped on the outer wall of the first screw barrel 3 or second screw barrel 6, thus completing the fixed installation of the first screw barrel 3 or second screw barrel 6.

[0030] Then, the crushed compressed foam or hot melt foam is fed into the first feed bin 4, located 1400cm away from the main screw barrel 1, by the auger. It then enters the first screw barrel 3, which has a diameter of 220cm and a length of 800cm. The first screw barrel 3 is equipped with spiral blades. The first motor 5 is started to drive the spiral blades to rotate and push the raw materials into the main unit. On the other side, the mixed raw materials are fed into the second feed bin 7, located 500cm away from the main unit. It then enters the second screw barrel 6, which has a diameter of 170cm and a length of 900cm. Spiral blades are also installed inside the second screw barrel 6. The second motor 8 is started to drive the spiral blades to rotate and push the raw materials into the main unit.
