Description

Technical Field

[0001] This utility model relates to the field of polymer material preparation, specifically to a cooling and temperature-reducing device for defoaming masterbatch. Background Technology

[0002] Defoaming masterbatch is a functional polymer additive mainly used to eliminate or suppress bubbles introduced during plastic processing due to high temperature, shear, or additives (such as lubricants and stabilizers), thus preventing products from having holes, surface defects, or performance degradation. The main preparation process is as follows: weigh the carrier resin, defoamer, dispersant, etc. according to the formula, put them into a high-speed mixer, add the mixture to an extruder, melt and blend at high temperature, and extrude the molten material into strips through the die. After preliminary cooling by water or air cooling, it is cut into cylindrical masterbatches of 2-5mm by a pelletizer.

[0003] After the molten material is extruded into strips through the die, it needs to be cooled quickly by a cooling device to prevent sticking or deformation. Traditional spray cooling uses fixed nozzles, which can only cover a specific area. During the transmission process, uneven cooling is easily caused by accumulation or deviation of the movement trajectory. In order to ensure full coverage, more nozzles need to be arranged, which leads to an increase in water consumption and a significant increase in water pump energy consumption.

[0004] To address this issue, we designed a defoaming masterbatch cooling device. Utility Model Content

[0005] The purpose of this invention is to provide a cooling and temperature-reducing device for defoaming masterbatch to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a cooling and temperature-reducing device for defoaming masterbatch, including a conveying device and a housing and a water tank disposed at the top of the conveying device. The housing is equipped with a driving mechanism, which includes:

[0007] Two rack rods are horizontally slidably disposed at the bottom of the two opposite inner walls of the housing, with their length direction consistent with the length direction of the housing. A sliding channel is opened on the side wall of the housing along the length direction of the housing and extends through the width direction of the housing. The end of the rack rod close to the sliding channel slides in the sliding channel and protrudes out of the sliding channel.

[0008] Multiple nozzles are rotatably mounted on one side wall of the rack protruding from the sliding channel, and the multiple nozzles are linearly and equally spaced along the length of the rack. A fixed rod is fixed between two adjacent nozzles, and a connecting pipe is fixed to the top of the nozzle. The ends of the multiple connecting pipes away from the nozzles are connected to the same water tank, which is fixed to the top of the housing.

[0009] Furthermore, the sidewalls of the two rack bars that are close to each other are tooth sides. The two ends of the sidewalls of the two rack bars that are close to each other along their own length direction are respectively meshed with horizontal sector gear one and sector gear two. Both sector gear one and sector gear two are rotatably mounted on the inner wall of the bottom of the housing. The rotation angles of sector gear one and sector gear two differ by 180 degrees, and the rack bar meshes with only one of sector gear one or sector gear two at a time. A sprocket is coaxially fixed to the top of sector gear two. A horizontal driven gear one is coaxially fixed to the top of sector gear one. A horizontal driven gear two is meshed on the side of driven gear one that is close to sector gear two. A motor is fixed to the bottom of driven gear two. The motor is fixed to the inner wall of the bottom of the housing. Another sprocket with the same structure is coaxially fixed to the top of driven gear two. The outer sides of the two sprockets are meshed with the same chain.

[0010] Furthermore, a fixed lug is rotatably fitted on the outer side of the nozzle, and the fixed lug is fixed to the side wall of the rack protruding from the sliding channel. The fixed lug allows the nozzle to rotate relative to the rack in the vertical plane along the width direction of the housing. At both ends of the bottom of the housing along its length, there are vertical support frames, which are fixed to the top of the transmission equipment. A limit post is fixed at the end of the fixed rod away from the nozzle near one end of the rack. The axial direction of the limit post is perpendicular to the axial direction of the fixed rod. A fixed cylinder coaxial with the fixed rod is fixed at the position of the limit post on the outer side wall of the housing. A spiral groove is opened on the side wall of the fixed cylinder near the fixed rod, and the limit post slides and adapts to the spiral groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The drive mechanism enables the nozzle to perform a combination of reciprocating linear motion and reciprocating oscillation. Specifically, sector gear one and sector gear two alternately mesh with the rack and pinion to drive the nozzle to move back and forth along the length of the housing, expanding the longitudinal coverage. The limiting post at the end of the fixed rod slides in the spiral groove of the fixed cylinder, forcing the nozzle to rotate synchronously during the movement, thus achieving lateral oscillating spraying.

[0013] 2. Because the spraying range is wider and more uniform, the number of nozzles in the same working area can be reduced, reducing the workload of the water pump and thus reducing the space occupied by the cooling channel. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1 To be continued Figure 4 This utility model provides a technical solution: a cooling and temperature-reducing device for defoaming masterbatch, including a conveying device 10 and a housing 12 and a water tank 13 disposed at the top of the conveying device 10. The housing 12 is provided with a driving mechanism, which includes:

[0024] Two rack rods 20 are horizontally slidably disposed at the bottom of the two opposite inner walls of the housing 12, and their length direction is consistent with the length direction of the housing 12. The rack rods 20 are provided with sliding channels that extend through the width direction of the housing 12 along the length direction of the housing 12 on the side wall corresponding to the housing 12. The end of the rack rod 20 near the sliding channel slides in the sliding channel and protrudes out of the sliding channel.

[0025] Multiple nozzles 14 are rotatably mounted on one side wall of the rack 20 protruding from the sliding channel, and the multiple nozzles 14 are linearly and equally spaced along the length of the rack 20. A fixed rod 16 is fixed between two adjacent nozzles 14. A connecting pipe 15 is fixed to the top of the nozzle 14. The ends of the multiple connecting pipes 15 away from the nozzles 14 are connected to the same water tank 13. The water tank 13 is fixed to the top of the housing 12.

[0026] The side wall of the two rack rods 20 that are close to each other is the tooth side. The two ends of the side of the two rack rods 20 that are close to each other along their own length direction are respectively meshed and connected to the horizontal sector gear 1 21 and sector gear 22. Both sector gear 1 21 and sector gear 22 are rotatably mounted on the inner wall of the bottom of the housing 12.

[0027] The rotation angles of the first sector gear 21 and the second sector gear 22 differ by 180 degrees, and the rack rod 20 meshes with only one of the first sector gear 21 or the second sector gear 22 at the same time.

[0028] A sprocket 23 is coaxially fixed to the top of the second sector gear 22. A horizontal driven gear 25 is coaxially fixed to the top of the first sector gear 21. A horizontal driven gear 26 meshes with the first driven gear 25 on the side near the second sector gear 22. A motor is fixed to the bottom of the second driven gear 26. The motor is fixed to the inner wall of the bottom of the housing 12. Another sprocket 23 with the same structure is coaxially fixed to the top of the second driven gear 26. The outer sides of the two sprockets 23 are meshed with the same chain 24.

[0029] In specific implementation, the conveying device 10 is used to transport the extruded strip material, and the surface of the conveying device 10 is made of stainless steel.

[0030] The initial rotation angles of sector gear 1 21 and sector gear 2 22 differ by 180 degrees, which means that when sector gear 1 21 meshes with one side of the rack 20 and moves outward, sector gear 2 22 meshes with the other side of the rack 20 and moves inward. Then, they synchronously exchange the meshed rack 20, causing them to move in opposite directions, thus realizing the interleaved reciprocating motion of the two rack 20.

[0031] The sprocket 23 and chain 24 enable sector gear 1 21 and sector gear 22 to rotate synchronously, while driven gear 1 25 and driven gear 26 enable sector gear 1 21 and sector gear 22 to rotate in opposite directions.

[0032] See appendix Figure 1 To be continued Figure 4 The nozzle 14 is rotatably fitted with a fixed ear seat on its outer side. The fixed ear seat is fixed to the side wall of the rack 20 protruding from the sliding channel. The fixed ear seat allows the nozzle 14 to rotate relative to the rack 20 in the vertical plane along the width direction of the housing 12. The bottom of the housing 12 has vertical support frames 11 at both ends along its length direction. The support frames 11 are fixed to the top of the transmission device 10.

[0033] A limiting post is fixed at the end of the fixing rod 16 near one end of the rack 20 away from the nozzle 14. The axial direction of the limiting post is perpendicular to the axial direction of the fixing rod 16. A fixing cylinder 17 coaxial with the fixing rod 16 is fixed at the position of the limiting post on the outer wall of the housing 12. A spiral groove is opened on the side wall of the fixing cylinder 17 near the fixing rod 16. The limiting post and the spiral groove are slidably adapted to each other.

[0034] In practice, when the rack 20 drives the nozzle 14 and the fixed rod 16 to move to the fixed cylinder 17, the limiting post at the end of the fixed rod 16 is inserted into the spiral groove on the fixed cylinder 17. When the limiting post slides in the spiral groove, the fixed cylinder 17 is fixed, thus forcing the limiting post to rotate, which in turn drives the fixed rod 16 to rotate, thereby driving the nozzle 14 to rotate. When the rack 20 moves in the opposite direction, the limiting post moves in the opposite direction in the spiral groove, thereby driving the fixed rod 16 to rotate in the opposite direction, thus realizing the swing spray.

[0035] Working principle: The conveying device 10 transports the extruded strip material, the surface of which is made of stainless steel. The motor drives the driven gear 26 to rotate, and the driven gear 25 causes the sector gear 21 and sector gear 22 to rotate in opposite directions and synchronously. The initial rotation angle difference between the two is 180 degrees, realizing the interleaved reciprocating motion of the two rack rods 20.

[0036] When the rack 20 moves, it drives the nozzle 14 and the fixed rod 16 on it to move. When it moves to the fixed cylinder 17, the limiting post at the end of the fixed rod 16 is inserted into the spiral groove 171 of the fixed cylinder 17. The limiting post slides and causes the fixed rod 16 to rotate, which drives the nozzle 14 to rotate around the fixed lug in the vertical plane where the width of the housing 12 is located. When the rack 20 moves in the opposite direction, the nozzle 14 rotates in the opposite direction to realize oscillating spraying. The water tank 13 supplies water to the nozzle 14 through the connecting pipe 15 to cool the material.
