Description

Technical Field

[0001] The invention relates to the technical field of polyester fiber granulation, in particular to a polyester fiber masterbatch processing extrusion granulation device. Background Art

[0002] The granulation of polyester fiber masterbatch refers to the process of processing hot-melt extruded polyester fiber strips into granules through raw material mixing, heating and melting, extrusion molding, cooling and shaping, cutting and granulation, quality inspection, packaging and storage and other processing techniques. Among them, cooling and shaping refers to the rapid cooling of the freshly extruded hot polyester fiber strips by air cooling or water cooling to fix their shape. The cooled polyester fiber strips can be cut into small particles later to obtain the required polyester fiber masterbatch. Cooling and shaping is not only crucial to ensure the consistency and dimensional stability of the final particles, but also to avoid adhesion during subsequent cutting, thereby ensuring the efficiency and quality of the granulation process.

[0003] However, there are still the following problems in the process of cooling and shaping polyester fiber strips:

[0004] (1) Static or uniformly circulating cooling water is usually used to cool a number of polyester fiber strips passing through a single cooling water pool. First, the water temperature of the polyester fiber strips tends to gradually increase during the cooling process. When a single cooling water pool is set up and the cooling water circulates slowly, the polyester fiber strips tend not to be cooled quickly and effectively. Second, a number of polyester fiber strips placed loosely in the cooling water pool tend to interfere with each other, affecting the molding effect of the polyester fiber strips.

[0005] (2) Usually, a number of polyester fiber strips that have been cooled by water are directly passed through a cover basket as a whole, and then cooling air is transported into the cover basket for air cooling. The general air cooling method cannot ensure that the polyester fiber strips at different positions are fully and effectively exposed to the air flow, which easily leads to the problem of inconsistent cooling degree. The air cooling effect and efficiency need to be improved.

[0006] Therefore, in order to solve the problems existing in the cooling and shaping process of polyester fiber strips, the present invention provides a polyester fiber masterbatch processing extrusion granulation equipment. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] See also Figure 1 and Figure 3 A polyester fiber masterbatch processing extrusion granulation equipment includes a cooling water pool 1, a workbench 2 is arranged on the right side of the cooling water pool 1, a partition 11 is installed between the front and rear inner walls of the middle part of the cooling water pool 1, and water cooling units 12 are arranged on the left and right sides of the partition 11. An air cooling unit 21 is arranged on the upper end of the workbench 2, and an extrusion device 3 and a cutting device 4 are arranged on the left side of the cooling water pool 1 and the right side of the workbench 2 respectively. The extrusion device 3 and the cutting device 4 are prior art, and the specific structures included are not shown in the figure.

[0035] See also Figure 1 , Figure 3 , Figure 4 and Figure 5The water cooling unit 12 includes two guide rollers 121 which are arranged on the left and right sides of the partition 11 and are rotatably installed between the front and rear inner walls of the cooling water pool 1. A support roller 122 is arranged above the guide roller 121 on the side close to the partition 11. The support roller 122 is rotatably installed between the front and rear vertical plates fixedly connected to the upper end surface of the cooling water pool 1. A transition roller 123 is rotatably installed between the upper ends of the right side of the cooling water pool 1. A conveying assembly is arranged between the left and right guide rollers 121 in the same sub-pool. The conveying assembly includes a conveyor assembly rotatably installed in front of the cooling water pool 1. The conveying rollers 124 are arranged evenly on the left and right between the rear inner walls, and are cam-shaped, and the protrusions of the conveying rollers 124 adjacent to the left and right are in opposite directions. The outside of the conveying rollers 124 is provided with limiting members evenly arranged front and back, and the limiting members include two limiting circular plates 125 which are sleeved on the outside of the conveying rollers 124 and arranged front and back. A stirring plate 126 evenly installed circumferentially on the outside of the conveying rollers 124 is provided between the limiting circular plates 125 adjacent to the front and back in different limiting members, and between the limiting circular plates 125 on the front and rear sides and the corresponding inner walls of the cooling water pool 1.

[0036] During operation: the cooling water pool 1 contains sufficient cooling water, and the polyester fiber strips in a high temperature state extruded from the extrusion device 3 gradually immerse into the cooling water in the cooling water pool 1 from the left, and the cooling water can pre-cool the polyester fiber strips in a high temperature state into a solid state.

[0037] When the polyester fiber strips are located in the cooling water pool 1 area on the left side of the partition 11, the existing technology can be used to pull multiple polyester fiber strips and simultaneously wind them out from under the guide roller 121 located on the left side, and the multiple polyester fiber strips that have passed the left guide roller 121 can be pulled to the top of the conveying rollers 124 arranged on the left and right. In this process, the multiple polyester fiber strips can be separated and placed one by one between the front and rear limiting circular plates 125 in the corresponding same limiting member, and the limiting member can be used to separate and guide the multiple polyester fiber strips to prevent the polyester fiber strips from being mutually bent during the rightward movement and cooling process. The conveying rollers 124 arranged on the left and right can continuously convey the polyester fiber strips from left to right, and after the polyester fiber strips pass through the conveying roller 124 on the rightmost side, multiple polyester fiber strips can be pulled again and simultaneously wound upward from the bottom of the guide roller 121 on the right side, and then the polyester fiber strips can be pulled upward to leave the cooling water pool 1 area on the left side of the partition 11 until above the support roller 122 on the left side.

[0038] Subsequently, the polyester fiber strips are pulled upward to above the support roller 122 on the right side, and then multiple polyester fiber strips can be pulled into the cooling water pool 1 area on the right side of the partition 11 in the same manner as described above. After multiple polyester fiber strips are wound upward from the guide roller 121 located on the right side at this time, the polyester fiber strips can continue to be pulled to the upper right to above the transition roller 123 to leave the cooling water pool 1 area on the right side of the partition 11, and then the polyester fiber strips that have wound around the transition roller 123 are moved right to the area where the air cooling unit 21 is located. The polyester fiber strips are separated and stably conveyed by the guide roller 121, the conveying roller 124, the support roller 122 and the transition roller 123, which can avoid the polyester fiber strips from being confused in the cooling water due to looseness and improve the uniformity of the polyester fiber strips during the cooling process.

[0039] The cooling water pool 1 can be divided into two left and right areas by the partition 11, so as to realize the regional cooling of the polyester fiber strips. This can prevent the cooling water with increased temperature from merging with each other in the same area during cooling, which would cause the overall temperature of the cooling water to increase. The polyester fiber strips can obtain effective water cooling, thereby improving the cooling effect and efficiency.

[0040] See also Figure 3 and Figure 5 The left and right sides of the partition 11 are both provided with stirring components located below the corresponding conveying components. The stirring components include a plurality of movable plates 111 evenly arranged on the left and right and slidably mounted on the upper end of the bottom wall of the cooling water pool 1. The upper end of the movable plate 111 is rotatably mounted with a propeller 112 evenly arranged front and back. The plurality of movable plates 111 are jointly installed between two front and rear strip plates 113 slidably connected to the bottom wall of the cooling water pool 1 left and right. The upper end of the strip plate 113 located on the front side is provided with tooth grooves evenly arranged on the left and right. The strip plate 113 located on the front side An arc-shaped plate 114 is arranged above and is rotatably connected to the inner wall of the front side of the cooling water pool 1. Teeth that are evenly arranged and matched with the tooth grooves are installed on the outer side of the arc-shaped plate 114. A sliding groove rod 115 is installed on the upper end of the arc-shaped plate 114. A rotating wheel 116 that is rotatably connected to the inner wall of the front side of the cooling water pool 1 is arranged on the front side of the sliding groove rod 115. A sliding column that is slidably connected to the sliding groove rod 115 is installed at the eccentric part of the rear end of the rotating wheel 116. A rotating column that rotates and penetrates the front end of the cooling water pool 1 is installed at the front end of the rotating wheel 116, and a connecting pulley 117 is installed at the front end of the rotating column.

[0041] See also Figure 1 and Figure 5A driving assembly for driving the conveying rollers 124 in different water-cooling units 12 to rotate synchronously is provided on the front side of the cooling water pool 1. The driving assembly includes a rotating shaft that is installed at the front end of the conveying rollers 124 in different water-cooling units 12 and passes through the front end of the cooling water pool 1. A transmission pulley 127 is installed at the front end of the rotating shaft. The transmission pulleys 127 arranged on the left and right are connected to the connecting pulley 117 through a belt 128. The front end of the leftmost transmission pulley 127 is connected to the output shaft of a motor 129. The motor 129 is installed on the front side of the cooling water pool 1 through a support.

[0042] During operation: when the polyester fiber strip passes through the cooling water pool 1, the transmission pulley 127 on the far left can be driven to rotate by the motor 129, and the transmission pulley 127 on the far left can drive the other transmission pulleys 127 to rotate synchronously through the belt 128, and the transmission pulley 127 drives the corresponding conveying roller 124 to rotate synchronously through the rotating shaft, and the rotating conveying roller 124 can continuously convey the polyester fiber strip to the right. In addition, since the conveying roller 124 is in a cam shape, and the protrusions of the left and right adjacent conveying rollers 124 are in opposite directions, the polyester fiber strip in the conveying process can swing back and forth up and down with the cam-shaped conveying roller 124, and the dynamic polyester fiber strip can be more fully in contact with the cooling water, thereby improving the cooling effect and cooling speed of the polyester fiber strip, and at the same time, the conveying roller 124 can drive the stirring plate 126 evenly arranged circumferentially to rotate synchronously, and the rotating stirring plate 126 can quickly and evenly stir the cooling water near the polyester fiber strip and the cooling water in other areas, increase the activity of the cooling water, accelerate the uniformity of the cooling water temperature, and effectively improve the cooling effect of the polyester fiber strip.

[0043] At the same time, the connecting pulley 117 rotates synchronously with the transmission pulley 127 through the belt 128, and the connecting pulley 117 drives the rotating wheel 116 to rotate synchronously through the rotating column. The rotating wheel 116 drives the arc plate 114 to swing back and forth left and right through the cooperation between the sliding column and the sliding groove rod 115. The arc plate 114 drives the strip plate 113 and the movable plates 111 distributed on the left and right to move back and forth along the bottom wall of the cooling water pool 1 through the cooperation between the teeth and the tooth grooves. The propellers 112 arranged front and back move synchronously with the corresponding movable plates 111. The propellers 112 that reciprocate left and right rotate under the action of the water flow that impacts the cooling water back and forth. The propellers 112 that reciprocate left and right can be used to stir the cooling water in the cooling water pool 1 while reciprocating left and right. During the injection of cold water, the cooling water heated around the polyester fiber strips is fully mixed with the cooling water at the bottom of the cooling water pool 1, thereby ensuring that the water temperature of the cooling water is uniform, which is beneficial to improving the consistency of the water cooling effect of the polyester fiber strips.

[0044] See also Figure 1 , Figure 2 and Figure 3A water injection assembly is arranged above the conveying assembly, a water outlet 131 is provided at the position corresponding to the water cooling unit 12 at the rear side of the cooling water pool 1, and the water outlet 131 is controlled by an existing electric control valve. A water storage tank 132 is arranged at the rear side of the cooling water pool 1 and is located between the left and right water outlets 131. A water suction pump is arranged inside the water storage tank 132. The water injection assembly includes a water injection pump 133 installed at the rear side of the cooling water pool 1. The water injection pump 133 and the rear end of the water suction pump are both provided with a connecting pipe connected to the existing cooling water supply equipment (the cooling water supply equipment is not shown in the figure), and two longitudinal pipes distributed on the left and right are arranged at the front side of the water injection pump 133. Channel 134, the front end of the longitudinal pipe 134 is fixedly connected to the support plate installed at the upper end of the cooling water pool 1, and a transverse pipe 135 evenly arranged front and back is connected between the left and right longitudinal pipes 134, the longitudinal pipe 134 is connected to the transverse pipe 135, and a water outlet head 136 evenly arranged left and right is installed at the lower end of the transverse pipe 135, a water suction device 137 is installed between the upper ends of the front and rear vertical plates, and two water supply pipes distributed front and back and located inside the cooling water pool 1 on the right side of the partition 11 are arranged on the right side of the water suction device 137, and a spray head 138 evenly arranged front and back is arranged at the lower end of the water suction device 137, and the upper end of the partition 11 is triangular.

[0045] During operation: in the process of cooling the polyester fiber strips in the cooling water pool 1, the water temperature of the cooling water pool 1 gradually increases. When the cooling water reaches a certain temperature, the water outlet 131 can be opened by the electric control valve. At this time, the cooling water with a higher temperature can flow into the water storage tank 132 through the water outlet 131. At the same time, the cooling water cooled by the cooling water supply equipment can be transported to the longitudinal pipe 134 through the connecting pipe by the water injection pump 133. The longitudinal pipe 134 transports the cooling water to the cooling water pool 1 area near the polyester fiber strips through the cooperation between the transverse pipe 135 and the water outlet head 136. The continuous fresh cooling water injected near the polyester fiber strips can quickly reduce the water temperature near the polyester fiber strips, ensuring that the polyester fiber strips are always fully and effectively cooled.

[0046] In addition, the water suction pump can transport the cooling water inside the water storage tank 132 to the cooling water supply equipment through the connecting pipe. The cooling water supply equipment can cool the cooling water with a certain temperature. The water injection pump 133 can input the cooled cooling water into the cooling water tank 1 again through the connecting pipe, thereby realizing the recycling of cooling water and effectively saving water resources.

[0047] Since the polyester fiber strips are transported from left to right, the water temperature in the cooling water pool 1 area on the left side of the partition 11 is higher than the water temperature in the cooling water pool 1 area on the right side of the partition 11. When the polyester fiber strips are located between the left and right support rollers 122, the water absorption device 137 can input the cooling water in the cooling water pool 1 area on the right side into the spray head 138 through the water supply pipe. The spray heads 138 arranged front and back can be used to spray and cool the polyester fiber strips at this time. The cooling water after spraying can flow along the partition 11 to the cooling water pool 1 areas on both sides of the partition 11.

The outside of the rotating column 222 is provided with a positioning member evenly arranged on the front and rear, and the positioning member includes two front and rear positioning circular plates 223 mounted on the outside of the rotating column 222.

[0050] See also Figure 6 and Figure 7The rotating assembly includes an outer gear ring 224 installed in the middle part of the outer side of the wind tube 214, and the outer gear rings 224 adjacent to the left and right are meshed with each other. The front side of the outer gear ring 224 located on the front side is meshed with a connecting gear 225, and the left end of the connecting gear 225 is connected to the output shaft of the motor 226 installed on the upper end of the workbench 2. The rear ends of the discs 221 located on the rear sides of the two auxiliary assemblies are both installed with mounting columns that rotate and penetrate the corresponding fixed plates 219, and the rear ends of the mounting columns are installed with bevel gears 1 227. The rear sides of the outer gear ring 224 located on the rear side are meshed with matching gears 228, and the matching gears 228 are rotatably installed between the left and right mounting plates 213 through the connecting columns 229. The left and right ends of the connecting columns 229 are both installed with bevel gears 230 that mesh with the corresponding bevel gears 1 227.

[0051] See also Figure 1-Figure 8 During operation: after the polyester fiber strips are pulled to the right and moved close to the workbench 2, the polyester fiber strips can continue to be moved to the right and enter the interior of the protective cover 211 from the flow port on the left side of the protective cover 211. At the same time, multiple polyester fiber strips are passed through the corresponding wind tubes 214 until the polyester fiber strips pass through the flow port on the right side of the protective cover 211. At this time, the polyester fiber strips can be air-cooled by the air cooling unit 21, and then the polyester fiber strips are moved to the right to the area where the cutting device 4 is located. The cutting device 4 can continuously cut the cooled and shaped polyester fiber strips into small particles while transporting the polyester fiber strips to the right, so as to obtain the required polyester fiber masterbatch. With the cooperation of the cutting device 4 and the extrusion device 3, the polyester fiber strips can be continuously transported from left to right.

[0052] When the polyester fiber strip passes through the air duct 214, the rotating rollers 218 arranged on the left and right can be used to support and guide the polyester fiber strip. At the same time, the rotating rollers 218 rotate synchronously with the rightward movement of the polyester fiber strip to ensure that the polyester fiber strip moves to the right smoothly and stably. In addition, the air cooler 216 can fill cooling air into the air duct 214 through the air duct. The air duct 214 uniformly applies the cooling air to the surface of the polyester fiber strip through the evenly distributed air outlets 215 to quickly cool the polyester fiber strip. At the same time, the connecting gear 225 can be driven to rotate by the motor 226, and the connecting gear 225 drives the outer gear ring 224 on the front side to rotate synchronously with the air duct 214. The remaining wind tube 214 rotates half a circle synchronously with the outer gear ring 224 through the cooperation between them, and then the connecting gear 225 can be driven by the motor 226 to rotate half a circle in the opposite direction again. The wind tube 214 and the outer gear ring 224 rotate half a circle synchronously. Since the air duct is a retractable hose, the air duct can be reciprocated around the outside of the wind tube 214 synchronously with the rotation of the wind tube 214. However, since the wind tube 214 reciprocates, the air duct will not continue to be wrapped around the wind tube 214 and affect the input of cooling air. The wind tube 214 arranged front to back and reciprocatingly deflected is used to perform synchronous dynamic surround air cooling on multiple polyester fiber strips separately, which helps to achieve a more consistent cooling effect and improve air cooling efficiency.

[0053] Before the polyester fiber strips enter the wind tube 214 and after passing through the wind tube 214, the polyester fiber strips are passed over the corresponding rotating column 222. In this process, multiple polyester fiber strips can be passed between the front and rear positioning circular plates 223 in the corresponding positioning members on the rotating column 222. The positioning members can limit, support and guide the polyester fiber strips entering the wind tube 214. During the reciprocating deflection of the wind tube 214, the matching gear 228 can rotate synchronously with the outer gear ring 224, and the matching gear 228 drives the left and right sides thereof through the connecting column 229. The bevel gear 230 on the left and right sides rotate synchronously, the bevel gear 230 drives the bevel gear 1 227 to rotate synchronously, the bevel gear 1 227 drives the disc 221 and the rotating column 222 to rotate synchronously through the mounting column. Since the rotating column 222 is installed at the eccentric position of the disc 221, the rotating columns 222 on the left and right sides can synchronously drive the polyester fiber strips to reciprocate up and down inside the air duct 214 to improve the activity of the polyester fiber strips during the air cooling process, increase the cooling area of ​​the polyester fiber strips, and thus further improve the air cooling quality and air cooling speed of the polyester fiber strips.

[0054] See also Figure 4 , Figure 5 and Figure 8 The guide roller 121, the support roller 122, the transition roller 123 and the rotating roller 218 are all provided with limiting grooves 141 which are evenly arranged front to back. The guide roller 121, the conveying roller 124 and the rotating roller 218 are all hollow structures, and the surfaces of the guide roller 121, the conveying roller 124, the rotating roller 218 and the limiting circular plate 125 are all provided with evenly arranged through holes.

[0055] During the process of cooling the polyester fiber strips, multiple polyester fiber strips can be placed in the corresponding limiting grooves 141 on the guide roller 121, the support roller 122, the transition roller 123 and the rotating roller 218 respectively. The limiting grooves 141 can limit the front and rear positions of the polyester fiber strips to avoid mutual interference between the polyester fiber strips and affect the cooling effect. In addition, the guide roller 121, the conveying roller 124, the rotating roller 218 and the limiting circular plate 125 with hollow structures and through holes can increase the degree of contact between the polyester fiber strips and the cooling water / airflow, so that the polyester fiber strips can obtain more sufficient water cooling or air cooling, and efficiently complete the rapid cooling of the entire polyester fiber strip.
