Description

Technical Field

[0001] The utility model relates to a material mixing production device. Background Art

[0002] During the production of colored yarn in the melt-spinning injection system, a dynamic mixer is configured to improve the uniformity of the melt. In the prior art, the shaft of the dynamic mixer rotates periodically, and the ends of the shaft need to be separated by asbestos boards to prevent heat conduction from causing damage to the bearings. The material entering the dynamic mixer is at high temperature, and the front end, rear end and flange head of the dynamic mixer need to be lubricated when rotating, and self-lubricated by extrusion of solid melt. To ensure that the slurry discharge at both ends of the dynamic mixer is normal, the discharge is in a semi-strip shape, and thin materials and dry powders are not allowed to be discharged (thin materials appear when the melt temperature is too high). This is because the discharge of thin materials will cause the entire discharge to stick to the equipment, which can easily block the equipment outlet; dry powders cannot play a lubricating role, and the equipment is prone to jamming.

[0003] Therefore, it is necessary to cool the front end, rear end and flange head of the dynamic mixer. The current operation is to cool the front end, rear end and flange head of the dynamic mixer by connecting three compressed air pipes and blowing them at the front end, rear end and flange head respectively. The three compressed air pipes are connected to the compressed air source respectively. The problems are:

[0004] The compressed air needs to be turned on manually, and the compressed air size needs to be adjusted each time to achieve the best cooling effect. The compressed air also needs to be turned off when the dynamic mixer stops. After manually adjusting the compressed air volume, the discharge situation should be observed every hour, and continuous observation for more than 24 hours can ensure that the compressed air size is appropriate. In actual operation, this method is difficult to control the compressed air size, resulting in more or less extruded solid melt, affecting the cooling effect. Since the compressed air is manually controlled, once the dynamic mixer fails to trip, the compressed air cannot be turned off in time. On the one hand, it causes a waste of compressed air. On the other hand, if the dynamic mixer trips and is not turned off in time, the compressed air will cool the dynamic mixer and solidify the melt, causing the dynamic mixer to be unable to be turned on. Since the compressed air size needs to be manually adjusted and difficult to control each time, if the compressed air is too large, the dynamic mixer shaft will be cooled, resulting in high resistance when the dynamic mixer rotates, and there is a risk of broken shaft. If the compressed air is too small, the melt is not cooled and cannot play a lubricating role. This operation method has high labor intensity, affecting production costs and production efficiency.

[0049] In some embodiments, the second material feeding unit includes a feeding pipeline 31, one end of the feeding pipeline 31 is connected to the mixer 1, and the other end of the feeding pipeline 31 is connected to the material feeding unit.

[0050] In some embodiments, the device also includes a drive assembly, which is used to drive the rotating shaft to rotate. The drive assembly includes a drive motor 22, a transmission shaft 23, and two couplings 24. The drive motor 22, a coupling 24, the transmission shaft 23, another coupling 24, and the rotating shaft are connected in sequence, that is, the drive motor 22 is connected to one end of the transmission shaft 23 through a coupling 24, and the other end of the transmission shaft 23 is connected to the rotating shaft through another coupling 24. A reducer 36 may also be provided between the drive motor 22 and one end of the transmission shaft 23.

[0051] In some embodiments, the device further includes two oiling units 19 and two fixing units 20. A oiling nozzle 241 is provided on the coupling 24. The oiling units 19 correspond one-to-one with the couplings 24 and are connected to the corresponding couplings 24 via a oiling pipe 37. The oiling units 19 are used to supply oil to the corresponding couplings 24. The fixing units 20 correspond one-to-one with the oiling units 19. The fixing units 20 are connected to both the drive shaft 23 and the oiling units 19, and are used to fix the oiling units 19. The couplings 24 require oil lubrication during operation. Lack of oil affects the operation of the couplings 24 and also affects the overall production schedule. Previously, oil was manually added to the couplings 24 when the device was not operating, which affected the production schedule and was inconvenient and unsafe. By providing the oiling units 19, the couplings 24 can be oiled autonomously.

The refueling gun includes a gun body 191 and a handle 192. The gun body 191 is used to contain oil, and the handle 192 is rotatably connected to the gun body 191. Operating the handle 192 can cause the oil in the gun body 191 to be transported to the coupling 24 through the refueling pipe 37, or prevent the oil in the gun body 191 from being transported to the coupling 24 through the refueling pipe 37. When the mixer 1 is operating, the gun body 191 continuously transports oil to the coupling 24, and the oil in the gun body 191 can be used for a long time (approximately two years). When the mixer 1 is not operating, the gun body 191 stops transporting oil to the coupling 24.

[0053] The fixing unit 20 of this example includes a first clamp 201, a connecting piece 202, and a second clamp 203. The first clamp 201 is arranged on the periphery of the transmission shaft 23, and the connecting piece 202 is connected to the first clamp 201 and the second clamp 203. The second clamp 203 is arranged on the periphery of the gun body 191. The second clamp 203 is used to fix the refueling unit 19, and a gap is maintained between the gun body 191 and the transmission shaft 23. The first clamp 201 and the second clamp 203 are both annular. The first clamp 201 and the second clamp 203 can both include two semi-annular clamps, and the two ends of the two semi-annular clamps are connected by fasteners (bolt and nut assemblies), or the first clamp 201 and the second clamp 203 can both be an annular clamp, one end of which is connected by a fastener (bolt and nut assembly).

[0054] In this example, two couplings 24 are provided, wherein one refueling unit 19 is located above the transmission shaft 23 and the other refueling unit 19 is located below the transmission shaft 23, so that the space can be fully utilized without affecting the work of each.

[0055] In some embodiments, an injection pump 28 is further provided between the first material feeding unit and the inlet of the screw extruder 27 to measure the amount of the first material entering the screw extruder 27 from the first material feeding unit.

[0056] The material mixing production device in this example is provided with a cooling unit and uses a cooling medium to cool the mixing unit, so as to avoid the mixer being cooled by the compressed air and the melt solidifying, which makes the mixer unable to be opened; and to avoid the difficulty in controlling the size of the compressed air manually. If the compressed air is too large, the rotating shaft of the mixer will be cooled, resulting in large resistance when the mixer rotates and the risk of broken shaft; if the compressed air is too small, the melt will not be cooled and will not play a lubricating role, thereby reducing labor intensity and improving production efficiency.

[0057] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
