Description

Technical Field

[0001] The invention belongs to the technical field of plastic production, in particular to a masterbatch production system. Background Art

[0002] Masterbatch, as a colorant for plastics, is made by mixing and grinding pigments, carriers and additives in a certain proportion, heating and melting them, extruding them in strips and then pelletizing them. The masterbatch needs to be cooled during the entire process from extrusion to pelletizing. Because the temperature of the molten masterbatch is extremely high, it makes the whole thing extremely soft. If it is not cooled in time through water, the quality of the masterbatch will be affected.

[0003] The molten masterbatch needs to stay in the water for a long time to be cooled, and most of the existing masterbatch cooling equipment achieves the cooling effect by increasing the length of the water tank to extend the time the masterbatch stays in the water. Although this can achieve the cooling effect, the longer water tank will seriously occupy the use space and the cooling efficiency is low.

[0004] In view of this, in order to overcome the above technical problems, the present invention designs and develops a masterbatch production system to solve the above technical problems. Summary of the invention

[0007] Preferably, the surface of the cooling roller is provided with a plurality of cooling grooves which are parallel to each other and arranged in a spiral shape. The number of the cooling grooves can be three, four, five or six. The specific number is based on the number of extruders extruded at one time and can be consistent with the extrusion number. The cross-sectional shape of the cooling grooves can be an inverted trapezoid, an inverted triangle, a rectangle or an arc, which can serve to limit the strip masterbatch.

[0008] Preferably, the upper slot width of the cooling slot is 6-8mm, and the pitch is 30-40mm. The width of the upper slot of the cooling slot can be selected to be 4-6mm or 8-10mm, mainly to ensure that the strip masterbatch can enter better and limit its position. The length of the pitch is based on the upper slot width to ensure that multiple cooling slots can be arranged in a spiral shape within the width left by the pitch, avoiding the problem of the first cooling slot being interlaced with the multiple cooling slots.

[0009] Preferably, a cavity is provided inside the cooling roller and a water pushing assembly is provided inside the cooling roller, and the water pushing assembly comprises:

[0010] Two bidirectional lead screws adopt a coaxial shaft structure and the two opposite faces are fixed together, and the back faces of the two faces are fixed to the front and rear end faces of the cooling roller cavity;

[0011] Two water push plates are respectively connected to the surface of the bidirectional lead screw by spiral transmission;

[0012] The limit rods are fixedly connected to the lower end walls of the two water push plates;

[0013] A limiting groove is provided at a position corresponding to the limiting rod at the lower end of the inner wall of the cooling roller;

[0014] Water holes are evenly arranged on the bottom end surface of the cooling line trough.

[0015] Preferably, the rotating shaft of the cooling roller passes through the rear end wall of the water tank and extends to the outside, and the rear half of the water tank is connected to a dehumidification component, which includes:

[0016] A cam fixedly connected to the surface of the extended portion of the rotating shaft;

[0017] The air collecting frame is fixedly connected to the upper right side of the rear end surface of the water tank, and has a chamber penetrating the upper end surface, and an air outlet and an air inlet are respectively opened at the bottom;

[0018] One-way valves are installed in the air outlet and air inlet respectively;

[0019] A plug plate is slidably connected in the inner chamber of the gas collecting frame;

[0020] The cam and the plug plate are respectively connected to one end of the connecting rod through hinges;

[0021] The gas rod is fixedly connected to the front upper part of the fixing seat through a connecting rod, and the lower end surface is provided with a gas outlet wall connected to the funnel-shaped chamber opened inside, and the right side wall is provided with an air inlet connected to the chamber;

[0022] The gas delivery pipe is fixedly connected between the gas inlet of the gas rod and the gas outlet of the gas collecting frame.

[0023] Preferably, the inner side wall at the front end of the water tank is fixedly connected to a limit plate, and the upper surface of the limit plate is fixedly connected to four groups of limit pieces.

[0024] Preferably, the diameters of the four groups of limit plates become smaller from top to bottom, so that even if the masterbatch is not aligned with the slot of the cooling trough at the first time, it can be ensured that the masterbatch can be accurately pulled into the cooling trough in the end.

[0025] Preferably, the surfaces of the two traction rollers are provided with concave-convex grooves which are staggered and meshed up and down, so that an extrusion traction force can be formed on the masterbatch after cooling, ensuring that the masterbatch can be smoothly sent to the next stage.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The present invention provides a masterbatch production system. After the molten masterbatch is extruded, it is promptly cooled in water and then wound on the surface of a cooling roller to continue moving forward in a spiral path. The spiral path can extend the time for the masterbatch to be immersed in water and cooled. The molten masterbatch is extremely hot and very soft when it just comes out. Therefore, the masterbatch is first cooled in water for a short period of time and then wound on the cooling roller. It is ensured that the masterbatch itself has a certain hardness before being wound on the surface of the cooling roller. This can avoid the extremely soft molten masterbatch being wound on the cooling roller at the first time, thereby affecting the quality of the final product.

[0028] 2. The present invention provides a masterbatch production system. During the production process, a water-pushing component is used to push the aqueous solution inside the cooling roller back and forth, so that the aqueous solution can flow back and forth between the masterbatches, thereby accelerating the water flow rate around the masterbatch. Compared with being in still water, the heat transfer of the masterbatch can be accelerated, and the water-pushing component can cause fluctuations in the water in the water tank, so that the water can also have a heat exchange process with the outside air, and a kind of cooling is also formed on the water itself, thereby avoiding the phenomenon of temperature increase of the water tank due to long-term use.

[0029] 3. The present invention provides a masterbatch production system, in which the cooling roller rotates to drive the dehumidification component to work together. The dehumidification component can remove water stains adhering to the surface of the masterbatch after water cooling, and can cool the masterbatch again. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0041] The present invention provides a masterbatch production system, which includes an extruder 1, a water tank 2 and two traction rollers 3. The extruder 1 is located at the left front part of the water tank 2, and a driving motor 21 is fixedly connected to the outer side of the front end wall of the water tank 2. The output shaft of the driving motor 21 extends through the inside of the water tank 2 and is fixedly connected to a cooling roller 4. The rear end face of the cooling roller 4 is fixedly connected to a rotating shaft and is rotatably connected to the rear end wall of the water tank 2 through a bearing. The two traction rollers 3 are horizontally distributed up and down through a mounting seat and are fixedly connected to the upper end face of the left side wall of the water tank 2 near the rear edge.

[0042] The driving motor 21 starts to drive the cooling roller 4 to rotate, and the extruder 1 extrude the molten masterbatch into the water tank 2, and the masterbatch is promptly cooled by water, and then the masterbatch is wound on the surface of the cooling roller 4 in a spiral path and continues to be immersed in the water tank 2 to complete cooling. The spiral path can extend the cooling time of the masterbatch in water, eliminating the need to increase the cooling path by extending the length of the water tank 2. The cooled masterbatch is dragged up by the mutual squeezing of the traction rollers 3 and is pulled to the next process link.

[0043] As a specific embodiment of the present invention, a plurality of cooling grooves 5 which are parallel to each other and arranged in a spiral shape are provided on the surface of the cooling roller 4, and the cross-sectional shape of the plurality of cooling grooves 5 is an inverted trapezoid.

[0044] The cooling groove 5 of the present invention can form a good limiting work for the masterbatch wound on the cooling roller 4, and the inverted trapezoidal cross-sectional shape can increase the contact area between the masterbatch and the aqueous solution. Except for the bottom part which is in contact with the cooling roller 4, the rest of the parts are exposed to the outside and can fully contact with the water, thereby ensuring the cooling efficiency of the masterbatch. The parallel cooling grooves 5 can avoid the problem of adjacent masterbatches sticking together when multiple masterbatches are simultaneously wound on the surface of the cooling roller 4 for transportation, thereby ensuring the quality of the final masterbatch product.

[0045] As a specific implementation of the present invention, the upper slot width of the cooling slot 5 is 6-8 mm, and the pitch is 30-40 mm.

[0046] The diameter of the masterbatch on the current market is mostly less than 5mm, so the cooling groove 5 with an upper groove width of 6-8mm can not only achieve a good limiting work for the masterbatch, but also maximize the contact area between the masterbatch and the water liquid, and the 30-40mm pitch will not affect the opening of multiple parallel cooling grooves 5, and can make full use of the surface area of ​​the cooling roller 4, thereby extending the running time of the masterbatch in the cooling groove 5.

[0047] As a specific embodiment of the present invention, a cavity 41 is provided inside the cooling roller 4 and a water pushing assembly is provided inside the cooling roller 4. The water pushing assembly includes:

[0048] Two bidirectional lead screws 22, the two opposite faces are fixed together, and the two back faces are fixed to the front and rear end faces of the cavity 41 of the cooling roller 4;

[0049] Two water push plates 6 are respectively connected to the surface of the bidirectional lead screw 22 by screw transmission;

[0050] The limiting rods 61 are fixedly connected to the lower end walls of the two water pushing plates 6;

[0051] The limiting groove 42 is provided at a position corresponding to the limiting rod 61 at the lower end of the inner wall of the cooling roller 4;

[0052] The water holes 51 are evenly arranged on the bottom end surface of the cooling line groove 5 .

[0053] When the driving motor 21 is started and drives the cooling roller 4 to rotate, it will also drive the water pushing assembly to work together. The two bidirectional screws 22 rotate at the same time, causing the corresponding water pushing plates 6 to reciprocate back and forth on the surface of the bidirectional screw 22 through a spiral transmission connection, and the sliding connection between the limit rod 61 and the limit groove 42 prevents the water pushing plate 6 from rotating with the bidirectional screw 22 and causing it to be stationary relative to the cooling roller 4. As a result, the water in the water tank 2 enters the cooling roller 4 cavity 41 through the water through hole 51 of the cooling line groove 5, and the internal water is pushed on the water pushing plate 6. Under the repeated pushing waves, the water will flow back and forth on the surface of the masterbatch through the water holes 51. The fast-flowing water can accelerate the hot and cold alternation around the masterbatch and improve the cooling effect on the masterbatch. Compared with the static water in the water tank 2, the repeated movement of the water pushing plate 6 will cause the aqueous solution in the water tank 2 to continuously generate water waves, thereby increasing the contact area between the water and the outside air and increasing the hot and cold alternation between the two. This can also cool the water itself, avoiding the problem of the masterbatch being cooled in the water for a long time and causing the water temperature to rise due to heat transfer.

[0054] As a specific embodiment of the present invention, the rotating shaft of the cooling roller 4 passes through the rear end wall of the water tank 2 and extends to the outside. The rear half of the water tank 2 is connected to a dehumidification component, and the dehumidification component includes:

[0055] The cam 43 is fixedly connected to the surface of the extension portion of the rotating shaft;

[0056] The air collecting frame 7 is fixedly connected to the upper right side of the rear end surface of the water tank 2, and has a chamber penetrating the upper end surface, and has an air outlet 711 and an air inlet 712 respectively formed at the bottom;

[0057] The one-way valve 71 is installed in the air outlet 711 and the air inlet 712 respectively. The one-way valve 71 in the air outlet 711 is opened only when air is discharged, and similarly, the one-way valve 71 in the air inlet 712 is opened only when air is inhaled;

[0058] The plug plate 8 is slidably connected in the inner chamber of the gas collecting frame 7 by adopting the single piston double-acting principle;

[0059] The cam 43 and the plug plate 8 are respectively connected to one end of the connecting rod through a hinge;

[0060] The gas rod 9 is fixedly connected to the front upper part of the fixing seat through a connecting rod, and the lower end surface is provided with a gas outlet wall 91 connected to the funnel-shaped chamber opened inside, and the right side wall is provided with a gas inlet 92 connected to the chamber;

[0061] The gas delivery pipe 72 is fixedly connected between the gas inlet 92 of the gas rod 9 and the gas outlet 711 of the gas collecting frame 7 .

[0062] After the existing masterbatch is cooled, it is mostly dried by air drying. Before air drying, water stains attached to the surface are first removed with a towel, sponge or brush to improve the air drying effect. However, these tools themselves have particularly high water absorption, and the water absorption effect will decrease after long-term use. Therefore, the present invention is equipped with a dehumidification component. When the cooling roller 4 rotates, the cam 43 is driven to rotate together through the rotating shaft. During the rotation of the cam 43, the plug plate 8 is made to slide back and forth in the chamber of the air collecting frame 7 through the connecting rod. Relative to the air collecting frame 7, the plug plate 8 moves upward, that is, inhales air. At this time, the one-way opening of the air inlet 712 draws the outside air into the air collecting frame 7, and then the plug plate 8 is pushed downward to exhaust air, and the air outlet hole 711 The one-way valve 71 is opened to transmit the absorbed air to the air rod 9 through the air pipe 72. Since the chamber of the air rod 9 is funnel-shaped and connected to the air outlet wall 91, the air pressure will increase when the air reaches the air outlet wall 91, and the wind blown by the air rod 9 is sufficient to blow off the water stains attached to the surface of the masterbatch pulled up by the traction roller 3 at the bottom, and the blown-off water stains will fall back into the water tank 2 to avoid the waste of water resources. Moreover, the wind blown by the air rod 9 can not only blow and cool the masterbatch, cooling it for a second time, but also blow directly to the aqueous solution in the water tank 2 to cool it. In this way, the masterbatch and the aqueous solution can be cooled while the water stains are removed.

[0063] As a specific embodiment of the present invention, the front inner wall of the water tank 2 is fixedly connected to a limit plate 23, and the upper end surface of the limit plate 23 is fixedly connected to four groups of limit pieces 231, and the diameters of the four groups of limit pieces 231 become smaller from top to bottom.

[0064] Because the extrusion port of the extruder 1 does not correspond one to one with the slot of the cooling groove 5, the molten masterbatch is first cooled in water after being extruded, and then transported to the cooling groove 5 on the surface of the cooling roller 4 under the traction of the limiting piece 231 of the limiting plate 23. The limiting piece 231 has a diameter from large to small, which allows the masterbatch to slowly shift to the correct path to prevent direct correction in a short period of time from causing certain damage to the surface of the masterbatch.

[0065] As a specific implementation of the present invention, the surfaces of the two traction rollers 3 are provided with concave and convex grooves which are staggered and meshed in an upper and lower manner.

[0066] The surface of the traction roller 3 of the present invention is provided with concave-convex grooves, and the concave-convex grooves of the lower traction roller 3 can limit the masterbatch pulled up, while the concave-convex grooves of the upper traction roller 3 and the concave-convex grooves of the lower traction roller 3 are staggered, so that the concave-convex surfaces of the two are meshed with each other. The meshing surfaces of the two traction rollers 3 can form an extrusion pressure on the masterbatch, pull up all the masterbatch at the bottom of the water tank 2, and transport them to the subsequent process links.

[0067] As a specific implementation of the present invention, the cooling roller 4 is made of Monel400 copper-nickel alloy material.

[0068] The cooling roller 4 of the present invention is installed in the water tank 2 and needs to be immersed in the aqueous solution for a long time, which is inevitably corroded by water. Therefore, Monel400 copper-nickel alloy is selected. This alloy material not only has excellent corrosion resistance in most water corrosion situations, but also rarely suffers from pitting corrosion and stress corrosion, and the corrosion rate is less than 0.025mm / a.

[0069] Working principle: The driving motor 21 starts to drive the cooling roller 4 to rotate, and the extruder 1 extrude the molten masterbatch into the water tank 2. The masterbatch is cooled by water in time, and then the masterbatch is wound on the surface of the cooling roller 4 in a spiral path and continues to be immersed in the water tank 2 to complete cooling. After cooling, the masterbatch is dragged up by the mutual squeezing action of the traction roller 3 and is pulled to the next process link.

[0070] When the driving motor 21 is started and drives the cooling roller 4 to rotate, it will also drive the water pushing assembly to work together. The two bidirectional screws 22 rotate at the same time, causing the corresponding water pushing plates 6 to be connected to the surface of the bidirectional screw 22 through a spiral transmission to make a reciprocating motion back and forth, and the sliding connection between the limit rod 61 and the limit groove 42 prevents the water pushing plate 6 from rotating together with the bidirectional screw 22 and causing it to be stationary relative to the cooling roller 4, so that the water in the water tank 2 enters the cooling roller 4 cavity 41 through the water hole 51 of the cooling line groove 5. Under the repeated pushing waves of the water pushing plate 6, the internal water will flow back and forth on the surface of the masterbatch through the water hole 51. The fast-flowing water flow can accelerate the alternation of hot and cold around the masterbatch and improve the cooling effect on the masterbatch. In addition, the water in the water tank 2 is stationary because the repeated movement of the water pushing plate 6 will cause the aqueous solution in the water tank 2 to continuously generate water waves, thereby increasing the contact area between the water and the outside air and increasing the alternation of hot and cold between the two. This can also cool the water itself.

[0071] When the cooling roller 4 rotates, the cam 43 is driven to rotate together through the rotating shaft. During the rotation of the cam 43, the plug plate 8 slides back and forth in the chamber of the air collecting frame 7 through the connecting rod. Relative to the air collecting frame 7, the plug plate 8 moves upward, that is, inhales air. At this time, the one-way opening in the air inlet 712 sucks the outside air into the air collecting frame 7. Then, when the plug plate 8 is pushed downward, the air is discharged. The one-way valve 71 in the air outlet 711 opens to transmit the absorbed air to the air rod 9 through the air pipe 72. The chamber is funnel-shaped and connected to the air outlet wall 91. Therefore, when the air reaches the air outlet wall 91, the air pressure will increase, thereby increasing the wind force. The wind blown out by the air rod 9 is sufficient to blow off the water stains attached to the surface of the masterbatch pulled up by the traction roller 3 at the bottom. The blown-off water stains will fall back into the water tank 2 to avoid the waste of water resources. Moreover, the wind blown out by the air rod 9 can blow-cool the masterbatch and cool it down for the second time. In this way, the masterbatch can be cooled again while the water stains are removed.

[0072] Assuming that the width of the water trough of the present invention and the existing water trough is the same as 500mm, the length of the existing water trough is 20000mm, the pitch s of the cooling groove of the present invention is set to 35mm, the diameter d of the cooling roller is 100mm, and the length h is (X)mm, then the total length of the cooling groove L = (d / s)*single turn L = (d / s)*sqrt(π*d)2+s 2 mm

[0073] The calculation is as follows: Cooling line slot single circle L = sqrt (3.14 * 100) 2 +35 2 =sqrt(99821)≈316mm

[0074] Total length of cooling trough = (X / 35)*L = 316X / 35 = 20000mm

[0075] Then: the height h of the cooling roller is 2222mm;

[0076] Then the cooling roller length of 2.222m is much less than 20m, so the length of the water tank of the present invention plus the wall width is 2.5m;

[0077] The existing water tank occupies an area of ​​10 square meters, while the water tank of the present invention occupies an area of ​​1.25 square meters;

[0078] The water tank of the present invention can save about 8.6 square meters of area.

[0079] Several specific implementation methods are listed above, which can be understood by relevant persons in the art.
