Description
Technical Field
[0001] This utility model relates to the field of hot melt device technology, and more specifically, to a device for collecting and reusing waste pearl cotton. Background Technology
[0002] Polyethylene foam, also known as EPE pearl cotton, is a non-crosslinked closed-cell structure made of low-density polyethylene resin through physical foaming to create countless independent air bubbles. EPE pearl cotton is recyclable and reusable. In most cases, it is used as a disposable protective material, and after use, it can be recycled and reprocessed. During recycling, because the old EPE pearl cotton is not of uniform size, and for better melting, it is often crushed before melting and molding. However, since EPE pearl cotton is made of organic materials, it releases certain organic waste gases during the hot melting process, which has a negative impact on the production environment and work. Therefore, a waste collection and reuse device for EPE pearl cotton is proposed. Utility Model Content

Detailed Implementation
[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0026] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.
[0027] See Figures 1 to 7This utility model provides a device for collecting and reusing waste pearl cotton, including a crusher 2, a hot-melt assembly 4, and a waste gas treatment box 5. The crusher 2 has a discharge port 27 at its bottom and a feed hopper 1 on its top. The inner cavity of the hot-melt frame has a guide cylinder 41, and a receiving box 42 is provided on the guide cylinder 41. The discharge port 27 is connected to the receiving box 42. A hot-melt cylinder 44 is provided at the output end of the guide cylinder 41. A preheating frame 45 is provided on the outer side of the end of the hot-melt cylinder 44 near the guide cylinder 41, and a heating frame group is provided on the side of the hot-melt cylinder 44 away from the preheating frame 45. 46. The hot melt cylinder 44 is provided with several air outlets, and air guide hoses are provided on the air outlets. All air guide hoses are connected to the waste gas treatment box 5. The crusher 2 and the hot melt assembly 4 are both connected to the rotating motor 3. The waste gas treatment box 5 is provided with two sets of catalyst frames. The waste gas generated in the hot melt cylinder 44 flows into the waste gas treatment box 5 through the air guide hoses. The output end of the hot melt assembly 4 is provided with an extrusion frame 8. After the material is hot melted, mixed and homogenized, it is squeezed into the extrusion frame 8 as it is inside the mixing cylinder 47. During this period, the temperature of the material decreases, and the material can be squeezed out and collected.
[0028] The rotating motor 3 controls the crusher 2 and the hot melt assembly 4 to start rotating simultaneously, cutting the pearl cotton material entering the crusher 2. The cut material is then pressed into the hot melt assembly 4 to complete the hot melt, mixing, and homogenization before being extruded to obtain new usable material. This material can be foamed again to obtain new pearl cotton or used for other purposes. During this process, the organic waste gas generated during the hot melt process is catalytically treated by the waste gas treatment box 5 to reduce the negative impact of the operation on the production environment.
[0029] See Figure 3 A fixed sleeve 43 is provided at the connection between the feed cylinder 41 and the hot melt cylinder 44. A mixing cylinder 47 is provided at the output end of the hot melt cylinder 44. The output end of the mixing cylinder 47 is connected to the extruder 8. A heat-insulating sleeve 48 is provided at the outer end of the mixing cylinder 47. The hot melt device consists of a feed cylinder 41, a hot melt cylinder 44 and a mixing cylinder 47. The feed cylinder 41 and the hot melt cylinder 44 are fixedly connected by the fixed sleeve 43. The hot melt cylinder 44 and the mixing cylinder 47 are designed as a single unit. The hot melt cylinder 44 is heated and the material state is changed by the preheating rack 45 and the heating rack group 46. Then, the material is kept in a hot melt state and is conveyed into the mixing cylinder 47. Two sets of propellers continuously homogenize it and further remove the gas carried by the material. During this period, the heat-insulating sleeve 48 continuously maintains the temperature of the material to avoid the temperature dropping too quickly and affecting its mixing effect.
[0030] When the material is pressed into the hot melt cylinder 44 from the guide cylinder 41, the compressed state isolates the gas phase channel between the leftmost end of the hot melt cylinder 44 and the guide cylinder 41, effectively preventing waste gas from flowing out of the guide cylinder 41. The material is rapidly melted within the hot melt cylinder 44, reducing the space occupied by the material and quickly releasing organic waste gas. Figure 3As shown, the air outlet is set on the hot melt cylinder 44, and the air guide hose is connected to the air outlet to conduct the organic waste gas generated by hot melting to the waste gas treatment box 5.
[0031] The air guide hose can be a combination of an external metal braided layer and an internal high-temperature resistant hose, or a combination of an external ultra-flexible corrugated pipe and an internal high-temperature resistant hose, so as to meet the production and use requirements and reduce the deformation of the pipe body. The exhaust gas treatment box 5 is equipped with a conduit on the mounting frame 9, and the air guide hose is connected to the exhaust gas treatment box 5 from the conduit.
[0032] See Figure 4 Multiple sets of feeding pipes are distributed on the insulation sleeve 48, and all feeding pipes are connected to the mixing cylinder 47. The outer shell of the hot melt component 4 is provided with a first additive box 6 and a second additive box 7. The output ends of the two sets of additive boxes are respectively connected to the feeding pipes at the corresponding positions. This solution does not limit the number and position of the additive boxes. By adding the target toughening agent, antioxidant, or stabilizer, color masterbatch, etc. into the mixing cylinder 47, the original properties of the material can be maintained or changed, and the new product can be used for other purposes.
[0033] The preheating frame 45 is configured as a first heat-conducting pipe wound around the hot melt cylinder 44. The first heat-conducting pipe is equipped with a heating resistance wire. The preheating frame 45 first heats the material in the hot melt cylinder 44. By controlling the power output to the heating resistance wire in the first heat-conducting pipe, the material can be preheated and compressed in advance, which is convenient for rapid melting in the later stage.
[0034] The heating frame group 46 includes multiple sets of heat-conducting pipes with the same structure as the preheating frame 45. Each set of heat-conducting pipes is equipped with an independent heating resistance wire. The heating frame group 46 provides an independent power supply for each set of heating resistance wires, which can adjust the heat supply inside the hot melt cylinder 44 after preheating, increasing the flexibility of electrothermal control. The input current of each set of heating resistance wires can be set by itself and adjusted in conjunction with the hot melt time limit, material fusion and mixing homogenization.
[0035] See Figure 5 and Figure 6The guide cylinder 41 and the hot melt cylinder 44 are equipped with a first propeller 411. The first propeller 411 has a drive gear 412 at the outer end of the guide cylinder 41. The first propeller 411 is fixedly connected to the output shaft of the rotating motor 3 through a rotating limiting sleeve 413. A second propeller 414 is provided next to the first propeller 411. The second propeller 414 is equipped with a driven gear 415. The drive gear 412 and the driven gear 415 are meshed. The output shaft of the rotating motor 3 drives the first propeller 411 to rotate at the same frequency. The drive gear 412 follows the rotation of the first propeller 411, which drives the driven gear 415 to make the second propeller 414 rotate at the same frequency and relative to the first propeller 411. This causes the guide screw frames and auger blades to rotate relative to each other. Thus, the first propeller 411 and the second propeller 414 complete the feeding, hot melt extrusion, mixing and homogenization and extrusion processing of the pearl cotton material, and transform the cut pearl cotton into extruded material particles.
[0036] The first propeller 411 and the second propeller 414 are equipped with a guide screw frame inside the guide cylinder 41. The guide screw frame is used to press the pearl cotton into the hot melt cylinder 44 one by one. The first propeller 411 and the second propeller 414 are equipped with auger blades of different specifications and arranged opposite each other in the hot melt cylinder 44 and the mixing cylinder 47. The first propeller 411 and the second propeller 414 are equipped with auger blades of different specifications and arranged opposite each other in the hot melt cylinder 44 and the mixing cylinder 47. The first propeller 411 and the second propeller 414 are used in the preheating, hot melting, mixing and extrusion stages of pearl cotton through the use of multiple sets of auger blades. Different specifications of auger blades are used for processing according to different stages, which can adjust the rhythm and uniformity of hot melting and mixing, and ensure the quality of hot melt output material.
[0037] See Figure 1 and Figure 2 The crusher 2 includes a rotating shaft 21, on which a cutting roller 22 is mounted. The cutting roller 22 is evenly equipped with several cutting blade holders 24. After the cleaned and dried pearl cotton enters the inner cavity of the crusher 2 through the feed hopper 1, the rotating shaft 21 drives the cutting roller 22 to rotate at high speed. Multiple sets of cutting blade holders 24 reciprocate to cut the pearl cotton. During the rolling process, the cutting roller 22 will transport the shredded pearl cotton to the left end of the inner cavity of the crusher 2 and flow into the guide cylinder 41. The left end of the cutting roller 22 is equipped with several flow control guide frames 23. The rotation of the flow control guide frames 23 can press the pearl cotton shreds into the guide cylinder 41.
[0038] The flow control guide frame 23 first compresses the pearl cotton fragments to expel the air from the existing air bubbles inside the pearl cotton, thereby reducing the exhaust pressure of the hot melt component 4.
[0039] The two sets of guide screw frames inside the guide cylinder 41 compress the pearl cotton again during the material transportation process. The guide cylinder 41 is connected to the outside world through the crusher 2, which can further squeeze the air carried by the pearl cotton out of the crusher 2.
[0040] The crusher 2 is mounted on the mounting frame 9. The crusher 2 has a second support frame 26 on the mounting frame 9 near the rotating motor 3. On the other side of the mounting frame 9, corresponding to the second support frame 26, there is a first support frame 25. The two ends of the rotating shaft 21 are rotatably connected to the first support frame 25 and the second support frame 26, respectively. The rotating shaft 21 has a driven pulley at the outer end of the second support frame 26. The mounting frame 9 is used to install the crusher 2, the rotating motor 3 and the hot melt assembly 4. The output shaft of the rotating motor 3 has a drive pulley. The drive pulley drives the driven pulley to rotate through the belt, thereby driving the rotating shaft 21 to run. The top left and right ends of the mounting frame 9 are supported by the second support frame 26 and the first support frame 25, respectively, to ensure that the rotating shaft 21 can rotate normally.
[0041] See Figure 1 and Figure 7 The catalytic frame includes a mounting frame 51, with a vertical frame 52 inside the mounting frame 51. Several UV lamps 53 are evenly arranged at the outer end of the vertical frame 52. Both sets of catalytic frames are fixedly installed in the waste gas treatment box 5 through the mounting frame 51. The mounting frame 51 supports the installation of the vertical frame 52 and provides installation support and limit for multiple sets of UV lamps 53. The waste gas treatment box 5 is a sealed box for catalytic waste gas. It emits ultraviolet light by supplying power to the UV lamps 53. The characteristics of ultraviolet light are used to catalyze organic waste gas, turning it into carbon dioxide, hydrogen and oxygen, which are harmless to the environment. The top of the waste gas treatment box 5 is equipped with a suction pump and a compression device to absorb hydrogen and compress and discharge it to avoid external accidents.
[0042] This utility model provides a device for collecting and reusing waste pearl cotton. After the waste pearl cotton has been washed and dried, it is put into the crusher 2 and cut into fragments. The fragments are then introduced into the hot melt cylinder 44 for heating and melting. Afterwards, the required additives can be added according to production needs. After mixing and homogenization, new material is output. The resulting material, after processing, will maintain or even improve the plastic properties and can be reused for pearl cotton foaming or other purposes, reducing the pressure of waste pearl cotton disposal and improving the efficiency of material reuse.
[0043] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
