Description

Technical Field

[0001] This utility model belongs to the field of wire drawing machine technology, and in particular relates to a water absorption device for water cooling after drawing recycled plastic wire. Background Technology

[0002] Inevitably, defective products will appear during the battery production process. Defective batteries need to be disassembled, recycled, and reused. For example, the plastic casing of the battery needs to be crushed, drawn into fibers, granulated, and then used to produce new battery casings using an injection molding machine.

[0003] For example, Chinese utility model CN220841388U discloses a water cooling device for a plastic filament drawing machine. After the plastic filament enters the cold water tank along the guide roller a and is cooled by water, it is guided between sponge a and sponge b, which can absorb the water on the surface of the plastic filament. Then, the air heated by the heating tube inside the drying rack moves inward to heat and dry the plastic filament inside.

[0004] In existing technology, scrapers a and b are used to squeeze sponges a and b respectively, squeezing out the water absorbed by sponges a and b to maintain their absorbency. However, during use, directly squeezing with scrapers not only results in poor water extraction but also makes the surfaces of sponges a and b easily scratched and damaged, affecting the overall absorbency and lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a water-absorbing device for water cooling after the plastic fibers are drawn from recycled plastic. The device uses a sponge roller and a squeezing roller to squeeze the water during their rotation, which solves the problems of existing sponge rollers being prone to scratching and damage and poor water extraction effect.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a water absorption device for water cooling after the plastic fibers are drawn from recycled plastic. It includes a cold water tank, with a pair of guide rollers rotatably connected to one end of the cold water tank. A mounting plate is fixedly connected to the cold water tank above the two guide rollers. The mounting plate is connected to a pair of mounting seats, each of which is rotatably connected to a vertically arranged sponge roller and a squeezing roller. The sponge roller and squeezing roller squeeze each other. A driving mechanism is connected to the mounting plate, synchronously driving the sponge roller and squeezing roller to rotate. The sponge roller and squeezing roller connected to the same mounting seat rotate in opposite directions.

[0007] As a preferred technical solution of this utility model, the circumferential surface of the extrusion roller is provided with axially arranged drainage channels for guiding the water flowing out from the extrusion of the sponge roller.

[0008] In a preferred embodiment of this invention, the lower end face of the extrusion roller is not higher than the lower end face of the sponge roller.

[0009] As a preferred embodiment of this utility model, driven wheels are fixedly connected to the upper ends of the rotating shafts of the sponge roller and the extrusion roller. A vertical plate is fixedly connected to the mounting base, and a bushing is rotatably connected to the vertical plate. The bushing is fixedly connected to a driving wheel that meshes with the driven wheel one by one. The driving mechanism includes a drive motor fixedly connected to the mounting plate. The output end of the drive motor is driven by a drive shaft, which passes through the two bushings to synchronously drive the sponge roller and the extrusion roller connected to the two mounting bases to rotate.

[0010] As a preferred embodiment of this utility model, the mounting base is slidably connected to the mounting plate, and the drive shaft is provided with an axially arranged sliding keyway and is connected to the two shaft sleeves by a sliding key.

[0011] As a preferred embodiment of this utility model, the mounting plate is rotatably connected to a bidirectional lead screw, and the vertical plates connected to the two mounting seats are each connected to a nut that cooperates with the bidirectional lead screw. By rotating the bidirectional lead screw, the distance between the two mounting seats can be adjusted.

[0012] This utility model has the following beneficial effects: This invention utilizes the mutual squeezing between a sponge roller and a squeezing roller, with the sponge roller and the squeezing roller rotating in opposite directions. By utilizing the mutual rotation of the sponge roller and the squeezing roller, water is squeezed out of the sponge roller, thereby effectively reducing the occurrence of sponge roller damage caused by scraping squeezing methods and effectively improving the overall service life.

[0013] Meanwhile, the mutual rotation and squeezing method allows the gap between the sponge roller and the squeezing roller to be minimized to the maximum extent, thereby improving the squeezing effect on the sponge roller and ensuring the overall squeezing and water output effect.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Example 1 Please see Figure 1 and 2 As shown, this utility model is a water absorption device for cooling recycled plastic filaments, including a cold water tank 1. One end of the cold water tank 1 is rotatably connected to a pair of guide rollers 101. After the plastic filaments are cooled by the cold water tank 1, they are pulled out from the guide rollers 101 and supported and guided by the two guide rollers 101.

[0020] like Figures 3-5 As shown, the cold water tank 1 is fixedly connected to a mounting plate 102 located above two guide rollers 101. The mounting plate 102 is connected to a pair of mounting seats 2, and both mounting seats 2 are rotatably connected to a vertically arranged sponge roller 3 and a squeezing roller 4.

[0021] The sponge roller 3 and the extrusion roller 4 are located between the two guide rollers 101. The sponge rollers 3 connected by the two mounting bases 2 are arranged opposite each other. The plastic filaments are supported by the guide rollers 101 and pass through the space between the two sponge rollers 3, thereby using the sponge rollers 3 to absorb and remove water from the surface of the plastic filaments.

[0022] The sponge roller 3 and the extrusion roller 4 on the mounting base 2 press against each other. The mounting plate 102 is connected to the drive mechanism 5, which drives the sponge roller 3 and the extrusion roller 4 to rotate synchronously. The sponge roller 3 and the extrusion roller 4 connected to the same mounting base 2 rotate in opposite directions, and the two opposite sponge rollers 3 rotate in opposite directions, which can adapt to the direction of plastic filament movement.

[0023] like Figure 6 As shown, the circumferential surface of the extrusion roller 4 is evenly provided with axially arranged drainage channels 401, which are used to guide the water flowing out when the extrusion roller 3 is extruded. By opening the drainage channels 401, the water flowing out when the extrusion roller 4 extrudes the sponge roller 3 can be quickly discharged through the drainage channels 401, thereby avoiding the situation of the sponge roller 3 being sucked back.

[0024] Furthermore, the lower end face of the extrusion roller 4 is not higher than the lower end face of the sponge roller 3, so that the water flow can flow out of the sponge roller 3 through the diversion channel 401, further ensuring the overall extrusion and drainage effect.

[0025] The specific driving method is as follows: the upper ends of the rotating shafts of the sponge roller 3 and the extrusion roller 4 are fixedly connected with driven wheels 301. The mounting base 2 is welded or bolted to a vertical plate 201. The vertical plate 201 is rotatably connected to a bushing 202 through a bearing. The bushing 202 passes through the vertical plate 201, and the outer wall of the bushing 202 is fixedly connected with a driving wheel 203 that meshes with the driven wheels 301. The driving wheel 203 and the driven wheel 301 are bevel gears that mesh with each other, and the two driving wheels 203 are located between the two driven wheels 301, thereby ensuring that the rotation directions of the sponge roller 3 and the extrusion roller 4 are opposite.

[0026] The drive mechanism 5 includes a drive motor 501 fixedly connected to the mounting plate 102. The output end of the drive motor 501 is connected to a drive shaft 502. Two mounting side plates are fixedly connected to the mounting plate 102. The drive motor 501 is connected to one of the mounting side plates. The two ends of the drive shaft 502 are rotatably connected to the two mounting side plates respectively. The mounting plate 102 is provided with a clearance slot. The vertical plate 201 passes through the clearance slot. The drive shaft 502 passes through two bushings 202, so that the bushings 202 are connected to the drive shaft 502, thereby realizing the synchronous drive of the two bushings 202 to rotate, that is, the synchronous drive of the sponge roller 3 and the extrusion roller 4 connected to the two mounting seats 2 to rotate.

[0027] Example 2 Based on Embodiment 1, the mounting base 2 and the mounting plate 102 are slidably connected by a guide rail slider. The drive shaft 502 has an axially arranged sliding keyway and is connected to the two bushings 202 by a sliding key, so that the bushings 202 can move axially relative to the drive shaft 502 while maintaining the transmission between the two.

[0028] Meanwhile, a bidirectional lead screw 103 is rotatably connected between the two mounting side plates of the mounting plate 102. The vertical plates 201 connected to the two mounting seats 2 are each connected to a nut 104 that cooperates with the bidirectional lead screw 103. One end of the bidirectional lead screw 103 is connected to a handwheel. By cooperating with the nut 104 and the bidirectional lead screw 103, the two mounting seats 2 can be driven to move towards each other or reversed to move away from each other. This allows for adjustment of the distance between the two mounting seats 2, thereby adjusting the distance between the two sponge rollers 3, ensuring good contact with the plastic filament surface, and improving the water absorption effect.

[0029] At the same time, by increasing the distance between the two mounting bases 2, it is easier to carry out maintenance work such as inspection or replacement of the components on the mounting base 2, such as the sponge roller 3, so as to further improve the overall ease of use and practicality.

Clearly, many modifications and variations can be made based on the content of this specification.
