Description

Technical Field

[0001] This utility model relates to the technical field of pearl cotton recycling equipment, specifically a pearl cotton briquetting machine. Background Technology

[0002] Pearl cotton, also known as polyethylene foam, is a new type of environmentally friendly packaging material with a non-crosslinked closed-cell structure. It is composed of countless independent air bubbles created through the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also exhibits excellent chemical resistance. It is an ideal substitute for traditional packaging materials. Its applications are very wide-ranging, mainly including: electronic product packaging, fragile item packaging, food packaging, express delivery packaging, the construction and decoration industry, and other application areas.

[0003] Currently, recycled waste pearl cotton is generally transported by hot melting and then granulation, which leads to inconvenience in transportation. In addition, hot melting requires heating and easily produces unpleasant odors during the process, making the processing environmentally unfriendly. Therefore, a fixed-length device for a foam plastic cold press, as disclosed in patent application number 201621340524.6, was developed. This structure uses a cylinder to drive a cutting blade to cut the product downwards. However, this structure has the problem of uneven cutting, and the cold pressing is performed directly after cutting, which affects the efficiency of cold pressing. After cold pressing, it is easy to have cracks due to incomplete cold pressing, which ultimately affects the subsequent transportation. Utility Model Content

[0004] The purpose of this utility model is to provide a pearl cotton briquetting machine to solve the problem mentioned in the background art that the existing pearl cotton cold pressing requires a cylinder to drive a cutting blade downward to cut the product. However, this structure has the problems of uneven cutting and cold pressing directly after cutting, which affects the efficiency of cold pressing and the problem of cracking due to insufficient cold pressing after cold pressing, which ultimately affects the later transportation effect.

[0024] Example 1

[0025] Please see Figures 1-6As shown, this embodiment discloses a pearl cotton briquetting machine, including a auger frame 1. A crushing chamber 3 is arranged above the auger frame 1, and a feed inlet 4 is arranged on the side of the crushing chamber 3. A crushing mechanism 5 for crushing pearl cotton is arranged inside the crushing chamber 3. One side of the auger frame 1 serves as a discharge port 6, and the other side of the auger frame 1 is arranged as a cold pressing briquetting mechanism 7 for cold pressing the pearl cotton conveyed by the crushing mechanism 5 and discharging it from the discharge port 6. A mixing chamber 2 is arranged below the crushing chamber 3 and communicates with the crushing chamber 3 and the auger frame 1 to facilitate later cleaning of the mixing chamber 2 and prevent clogging. The front and rear of the mixing chamber 2 are hinged with cover plates 201, which can be opened later to clean the inside of the mixing chamber 2. A mixing mechanism 8 and a heating pipe 9 are arranged inside the mixing chamber 2. One or more air nozzles 10 are distributed on the heating pipe 9. The crushing mechanism 5 includes a reduction motor 501, a cutting spindle 502, and a cutting blade 503. 501 is fixed to the outside of the crushing chamber 3. The output shaft of the geared motor 501 is connected to one end of the cutting spindle 502 through the coupling 11. The cutting spindle 502 is inserted into the crushing chamber 3, and one or more cutting blades 503 are spaced apart on the cutting spindle 502. The heating tube 9 is connected to a low-temperature dryer 15. The heating temperature of the low-temperature dryer 15 is controlled at about 60 degrees to prevent the product surface from having moisture and making it difficult to shape. At the same time, the low-temperature dryer 15 is used to soften the pearl cotton at low temperature. Since the low temperature does not produce odor or harmful substances, it is more environmentally friendly and also facilitates the compression of the oil cylinder later. The cutting blades 503 are four-blade blades. For easy operation, a gantry frame 101 is set above the auger frame 1. A control box 102 for controlling the operation of the equipment is set on the gantry frame 101. The control box 102 is electrically connected to the geared motor 501, the oil tank motor 702, and the electromagnetic reversing valve 703 to realize the electrical control of each piece of equipment.

[0026] Preferably, to simplify the structure, reduce the number of parts, and enable a single motor to control both the stirring and cutting mechanisms simultaneously, thereby reducing costs, a sprocket 12 is provided at the other end of the cutting spindle 502 after extending out of the crushing chamber 3. The stirring mechanism 8 includes a stirring spindle 801 and stirring rods 802. The stirring spindle 801 is rotatably inserted into the stirring chamber 2, and one or more stirring rods 802 are spaced apart on the stirring spindle 801, with each stirring rod 802 having a different distribution angle. At the end of each stirring rod 802 away from the stirring spindle 801, there is a stirring plate 803. A sprocket 2 804 is connected to one end of the stirring spindle 801 after extending out of the stirring chamber 2. A chain 805 is provided between the sprocket 2 804 and the sprocket 12. A sprocket guard 806 is provided between the crushing chamber 3 and the stirring chamber 2 to cover the chain 805, the sprocket 12, and the sprocket 2 804.

[0027] To improve the subsequent cold pressing effect, two sets of heating pipes 9 are respectively arranged on the front and rear sides of the mixing chamber 2. An L-shaped heating conveying pipe 13, connected to the two heating pipes 9, is located on the outside of the crushing chamber 3. The other end of the L-shaped heating conveying pipe 13 is connected to a heating fan 14, which is fixed to the side of the crushing chamber 3. The other end of the heating fan 14 is connected to a low-temperature dryer 15 on the side of the crushing chamber 3. To improve the heating effect, the heating pipes 9 are square tubes, and the blowers on the two square tubes... The air nozzle 10 is mirror-set and located inside the square tube. In this structure, two sets of mirror-set heating tubes 9 are added to the mixing chamber 2, and the heating tubes 9 are equipped with air nozzles 10. The heating fan 14 absorbs the cold air from the outside and heats it to the preset temperature through the low temperature dryer 15. Then, the heating fan 14 delivers the hot air to the heating tubes 9 through the L-shaped heating conveying pipe 13 and blows it out from the air nozzles 10. The crushed pearl cotton in the mixing chamber 2 is then heated and conveyed to the bottom, which facilitates more uniform cold pressing in the later stage.

[0028] Preferably, the cold pressing block mechanism 7 includes an oil tank 701, an oil tank motor 702, an electromagnetic reversing valve 703, a hydraulic cylinder 704, and a pressure head push plate 705. The oil tank 701 is fixed above the winch frame 1. The oil tank motor 702 and the electromagnetic reversing valve 703 are fixed above the oil tank 701. The output shaft of the oil tank motor 702 is connected to a plunger pump 706. One end of the plunger pump 706 is connected to the oil tank 701, and the other end is connected to the hydraulic cylinder 704 via the electromagnetic reversing valve 703. The cylinder barrel 704 is fixed to one side of the auger frame 1. The cylinder rod on the cylinder barrel 704 is inserted into the auger frame 1 and connected to the pressure head push plate 705. The pressure head push plate 705 is provided with a pressure head top plate 707 above it, which can close the opening below the crushing chamber 3 when the stirring mechanism 8 is working. In order to ensure the stability of the pressure head push plate 705 when it moves, a pressure head side plate 708 is provided on both the front and rear sides of the pressure head push plate 705. The outer wall of the pressure head side plate 708 is in contact with the inner wall of the auger frame 1.

[0029] It should be noted that the specific models of the oil tank 701, oil tank motor 702, electromagnetic reversing valve 703, oil cylinder barrel 704, and plunger pump 706, as well as how the oil tank motor 702 controls the plunger pump 706 to work and thus enable the oil cylinder barrel 704 to work, are conventional technologies in the field and therefore will not be described in detail.

[0030] The working principle of this structure is as follows: After the recycled pearl cotton enters through the feed inlet 4, the geared motor 501 is started. The geared motor 501 drives the cutting main shaft 502 to rotate, and then the pearl cotton in the crushing chamber 3 is cut and crushed by multiple cutting blades 503. The multiple cutting blades 503 (each cutting blade 503 has four blades) further improve the cutting efficiency and ensure more uniform cutting. At the same time as cutting, the sprocket 1 12, chain 805 and sprocket 2 804 synchronously drive the stirring main shaft 801 to rotate, and synchronously drive the stirring rods 802 at different angles to rotate. The stirring plate 803 then crushes the cut pearl cotton. The formed pearl cotton is stirred (during the stirring process, the pressure head top plate 707 below seals the opening below the crushing chamber 3). During the stirring process, the heating pipe 9 and the air nozzle 10 blow low-temperature hot air to the pearl cotton in the stirring chamber 2 to evenly dry the moisture and heat it, preventing the product surface from having moisture and making it difficult to shape. At the same time, a low-temperature dryer 15 is used to melt the pearl cotton at a low temperature. Since the low temperature does not produce odors or harmful substances, it is environmentally friendly. Moreover, the pearl cotton crushed material is softened at low temperature (by heat) so that it loses its elasticity, which facilitates the degassing during the subsequent compression process and ultimately ensures an increase in the compression ratio.

[0031] After the mixing is completed, the cylinder 704 is driven to work. First, the pressure head push plate 705 is moved towards the cylinder 704 to expose the opening below the crushing chamber 3. The heated and mixed pearl cotton is dropped from below the crushing chamber 3 into the auger frame 1. Then, the cylinder 704 is driven to continue working, pushing the pressure head push plate 705 towards the discharge port 6 on the other side. After being shaped and fixed by the chamber body of the auger frame 1 for a period of time, it is pushed out from the discharge port 6. Thus, the low-temperature softened pearl cotton is squeezed under high pressure and discharged from the discharge port 6.

[0032] Therefore, this structure employs a method of first cutting, then uniformly drying at low temperature to remove moisture, softening at low temperature, and stirring, followed by cold pressing in a hydraulic cylinder to further ensure uniform cold pressing. The pearl cotton is also melted at low temperature, which prevents the generation of odors and harmful substances, thus achieving environmental protection. Furthermore, the low-temperature softening of the pearl cotton powder makes it lose its elasticity (when heated), facilitating venting during subsequent compression and ultimately ensuring a higher compression ratio. This ensures better extrusion molding results and facilitates later transportation. The method of uniform heating and stirring after cutting further avoids cracking problems caused by inadequate cold pressing (due to uneven cutting and inconsistent particle size).

[0033] Furthermore, this structure can achieve a compression ratio of 30:1. Through crushing, drying and softening, and finally compression by hydraulic cylinders, a compression ratio of 30:1 can be guaranteed, while the compression ratio of ordinary equipment can only reach 2:1. Experiments have shown that normal pearl cotton has a density of 20-30 kg / m³, while the density after compression by this structure is about 600-800 kg / m³, making the compression more compact and easier to transport.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
