Description

Technical Field

[0001] The invention belongs to the technical field of stool drainage devices, and in particular relates to a water ring pelletizing mechanism for masterbatch production. Background Art

[0002] Masterbatch is composed of three basic elements: pigment, carrier and additive. It is a special colorant for polymer materials. In the production process, masterbatch needs to be mixed and granulated. Granulation is done by extruding the mixed material from a mold with several small holes, and cutting it in the process of extrusion to form granules.

[0003] During the ring cutting process, on the one hand, we need to consider how to quickly cool the extruded material, and on the other hand, we need to consider how to avoid burrs on the masterbatch when the cutting edge of the cutter becomes blunt. If there are burrs on the masterbatch, it will affect the subsequent drying effect and cause the water content of the masterbatch to increase, which does not meet the requirements. Therefore, a water ring cutting mechanism for masterbatch production is proposed. Summary of the invention

[0006] Preferably, a connecting column is fixedly connected to one end of the main shaft close to the extrusion die, the diameter of the connecting column is smaller than the diameter of the main shaft, a mounting disk is slidably connected to the connecting column, the cutter is mounted on the mounting disk, and a spring is sleeved on the connecting column.

[0007] Preferably, the connecting column is symmetrically provided with limiting grooves, the inner diameter of the mounting plate is symmetrically provided with limiting blocks, the limiting blocks slide in the limiting grooves, the mounting plate is provided with countersunk grooves, and the mounting plate is detachably connected to the connecting column by bolts on the end cover.

[0008] Preferably, three connecting arms are fixedly connected to the circumference of the mounting plate, and an inclined groove is provided on the connecting arm. The cutter is installed on the inclined groove so that the cutter is inclined.

[0009] Furthermore, one end of the cutter away from the extrusion die extends toward the main shaft, and a waist-shaped hole is provided on the cutter.

[0010] Furthermore, a guide chute is provided on a surface of the second arc-shaped plate facing the main axis, both ends of the guide chute pass through two sides of the second arc-shaped plate, and the guide chute faces the discharge outlet.

[0011] Furthermore, an impact tube is fixedly connected to one surface of the stirring plate, and an open end of the impact tube faces the extrusion die.

[0012] Preferably, a plurality of beveled tubes are obliquely fixedly connected to the impact tube, and the beveled tubes penetrate to the other side of the stirring plate.

[0013] A masterbatch production and pelletizing method mainly comprises the following steps:

[0014] S1. The main shaft drives the cutter to cut the material extruded from the extrusion die, and when the main shaft rotates, the coolant in the shell is driven to rotate through the stirring plate, so that the coolant in the shell flows;

[0015] S2, the cut material passes through the first curved plate, the second curved plate, and the stirring plate, so that the material contacts the polishing pad for polishing;

[0016] S3, and make the coolant in the shell flow to the discharge port through the guide chute, and discharge the cooled material through the discharge port for subsequent operation.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0018] 1. The water ring pelletizing mechanism used for masterbatch production innovatively allows the forming hole of the extrusion die to be passed into the coolant, which enables the material to be cooled immediately during the extrusion process, thereby accelerating the cooling effect and avoiding the wire drawing phenomenon caused by the viscosity of the material during cutting;

[0019] In addition, by providing the first arc plate, the second arc plate, and the stirring plate, the cooling path of the cut material can be effectively extended, so that the flow path of the material in the shell is increased, thereby accelerating the cooling effect of the material.

[0020] 2. The water ring pelletizing mechanism for masterbatch production, when the stirring plate rotates through the second curved plate, the coolant and part of the material are hit on the second curved plate, and part of the material rotates around the main axis, and the coolant and material hitting the second curved plate will flow to the first curved plate close to the second curved plate after being blocked by the second curved plate, and a polishing pad is provided in the angle between the first curved plate and the shell, so that part of the material will contact the polishing pad to polish the material and reduce the presence of burrs on the material;

[0021] 3. The water ring pelletizing mechanism for masterbatch production has a guide chute on the second curved plate. When the stirring plate passes through the second curved plate, the coolant will flow obliquely due to the setting of the guide chute. At the same time, a part of the coolant that impacts the second curved plate will be reflected to the polishing pad through the guide chute, thereby effectively improving the polishing effect of the material;

[0022] When the coolant flows obliquely, the cooled material will move closer to the discharge port. Since the external water pump will continuously pump the coolant into the shell and flow out from the discharge port, the material will be discharged from the discharge port and then be spun and dried to complete the production.

[0023] 4. The water ring pelletizing mechanism used for masterbatch production has a stirring plate that contacts the coolant on one side of the stirring plate when the stirring plate rotates with the main shaft, so that the water pressure on one side of the stirring plate increases. At this time, the coolant enters the impact tube through the oblique cutting tube and is then discharged from the open end of the impact tube. The impact tube is aligned with the extrusion die, so that when the cutter cuts and separates the material, the coolant with a certain pressure discharged from the impact tube can quickly disperse the cut and separated material to avoid accumulation;

[0024] In addition, due to the concentration of forming holes, the heat of the material that has not been cut is easily concentrated during the extrusion process. Therefore, the coolant discharged from the impact tube can also cool the uncut material, further improving the cooling effect on the material. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0036] Example 1: Reference Figure 1-Figure 8A water ring pelletizing mechanism for masterbatch production includes a housing 1 provided with an extrusion die 11, and further includes: a coolant circulated in the housing 1; a main shaft 13, rotatably connected to the housing 1, a cutter 154 is circumferentially provided on one end of the main shaft 13 close to the extrusion die 11, the cutter 154 is in contact with the surface of the extrusion die 11, and is used to cut the overflow of the forming hole 12 of the extrusion die 11 through the cutter 154 when the main shaft 13 rotates; a plurality of first arc plates 2 circumferentially provided on the inner wall of the housing 1; a plurality of second arc plates 3 circumferentially provided on the inner wall of the housing 1, A plurality of second curved plates 3 are respectively located between adjacent first curved plates 2; a plurality of stirring plates 16 are circumferentially arranged on the outer circumference of the main shaft 13; a polishing pad 4 is arranged at an angle between a side of the first curved plate 2 away from the main shaft 13 and the inner wall of the housing 1, when the main shaft 13 rotates and drives the stirring plates 16 to stir the coolant in the housing 1, the coolant hits the second curved plates 3 and rebounds to the angle between a side of the first curved plate 2 away from the main shaft 13 and the inner wall of the housing 1, and the coolant is diverted at the angle; a discharge port 17 is arranged on the side of the housing 1 at one end away from the extrusion die 11;

[0037] When the device is in use, the main shaft 13 drives the cutter 154 to cut the material extruded from the extrusion die 11, and the stirring plate 16 on the main shaft 13 drives the coolant in the housing 1 to rotate, so that the coolant in the housing 1 further flows, so that the material cut by the cutter 154 rotates in the housing 1, so that the material is cut by the cutter 154. Figure 3 Taking the viewing angle as an example, the main axis 13 rotates clockwise;

[0038] When the stirring plate 16 rotates and passes through the second curved plate 3, the coolant and part of the material are hit on the second curved plate 3, and part of the material rotates around the main shaft 13. The coolant and material hitting the second curved plate 3 will flow to the first curved plate 2 close to the second curved plate 3 after being blocked by the second curved plate 3. A polishing pad 4 is provided in the angle between the first curved plate 2 and the housing 1, so part of the material will contact the polishing pad 4 to polish the material and reduce the presence of burrs on the material.

[0039] When the flowing coolant reaches the angle between the first curved plate 2 and the shell 1, it will be blocked and will return, so a vortex is formed at the angle between the first curved plate 2 and the shell 1, which can fully and effectively polish the material;

[0040] Specifically, the diameter of the first curved plate 2 is greater than the diameter of the second curved plate 3, so the arc of the first curved plate 2 is slightly gentle, while the arc of the second curved plate 3 is bent at a larger angle, which makes one end of the second curved plate 3 closer to the stirring plate 16. Therefore, during the rotation of the stirring plate 16, the driven coolant can rely on the curvature of the first curved plate 2, so that a large amount of flowing coolant impacts the second curved plate 3, so that more materials can move to the location of the polishing pad 4, thereby effectively improving the polishing effect of the material;

[0041] In addition, the device innovatively allows the forming hole 12 of the extrusion die 11 to be passed into the coolant, so that the material can be immediately cooled during the extrusion process, thereby accelerating the cooling effect, thereby avoiding the phenomenon of wire drawing during cutting due to the viscosity of the material;

[0042] In addition, by providing the first arc plate 2, the second arc plate 3, and the stirring plate 16, the cooling path of the cut material can be effectively extended, so that the flow path of the material in the shell 1 is increased, thereby accelerating the cooling effect of the material.

[0043] Example 2: Reference Figure 1-Figure 8 A water ring pelletizing mechanism for masterbatch production, comprising a housing 1 provided with an extrusion die 11, and further comprising: a coolant circulating in the housing 1; a spindle 13, rotatably connected in the housing 1, a cutter 154 circumferentially provided on one end of the spindle 13 close to the extrusion die 11, the cutter 154 contacts the surface of the extrusion die 11, and is used to cut the overflow material of the forming hole 12 of the extrusion die 11 through the cutter 154 when the spindle 13 rotates; a plurality of first arc plates 2 circumferentially provided on the inner wall of the housing 1; a plurality of second arc plates 3 circumferentially provided on the inner wall of the housing 1, the plurality of second arc plates 3 are respectively located between adjacent first arc plates 2; a plurality of stirring plates 16 circumferentially provided on the outer periphery of the spindle 13; a polishing The light pad 4 is arranged at the angle between the side of the first curved plate 2 away from the main shaft 13 and the inner wall of the shell 1. When the main shaft 13 rotates and drives the stirring plate 16 to stir the coolant in the shell 1, the coolant hits the second curved plate 3 and rebounds to the angle between the side of the first curved plate 2 away from the main shaft 13 and the inner wall of the shell 1, and the coolant is turned at the angle; the discharge port 17 is arranged on the side of the end of the shell 1 away from the extrusion die 11: a connecting column 14 is fixedly connected to the end of the main shaft 13 close to the extrusion die 11, the diameter of the connecting column 14 is smaller than the diameter of the main shaft 13, and a mounting plate 15 is slidably connected to the connecting column 14, and a cutter 154 is installed on the mounting plate 15. A spring 142 is sleeved on the connecting column 14;

[0044] The connection column 14 is symmetrically provided with a limiting groove 143, and the inner diameter of the mounting plate 15 is symmetrically provided with a limiting block 152, the limiting block 152 slides in the limiting groove 143, and the mounting plate 15 is provided with a sink groove 151, and the mounting plate 15 is detachably connected to the connection column 14 through the bolt 144 on the end cover 141;

[0045] Three connecting arms 153 are fixedly connected to the mounting plate 15, and the connecting arms 153 are provided with inclined grooves, and the cutter 154 is installed on the inclined grooves, so that the cutter 154 is inclined;

[0046] The end of the cutter 154 away from the extrusion die 11 extends toward the main shaft 13, and a waist-shaped hole 155 is formed on the cutter 154;

[0047] The cutter 154 of the device can be provided with a spring 142 so that the cutter 154 is closely attached to the surface of the extrusion die 11, thereby facilitating cutting. When the cutter 154 contacts the extrusion die 11, the main shaft 13 drives the cutter 154 to rotate, which can also have the effect of automatically grinding the cutting edge of the cutter 154.

[0048] When installing the cutter 154, the spring 142 is sleeved on the connecting column 14, and then the limiting block 152 on the mounting plate 15 is aligned with the limiting groove 143 on the connecting column 14, so that the mounting plate 15 is sleeved on the connecting column 14, and then the end cover 141 is placed in the sink groove 151 of the mounting plate 15, and the end cover 141 is connected to the connecting column 14 by the bolt 144, so as to realize the installation of the mounting plate 15;

[0049] The cutter 154 is mounted on the inclined groove of the connecting arm 153, so that the cutter 154 can be directly inclined without adjusting the angle between the cutter 154 and the extrusion die 11;

[0050] Extending one side of the cutter 154 can guide the material when cutting it, preventing the material from gathering after being cut, and the waist-shaped hole 155 can reduce the resistance of the cutter 154 when the cutter 154 rotates with the main shaft 13, so that the coolant can move the material away from the extrusion die 11 faster when passing through the waist-shaped hole 155.

[0051] Example 3: Reference Figure 3 , Figure 4 , Figure 5 , a water ring pelletizing mechanism for masterbatch production, which is basically the same as that of Example 2, and furthermore: a guide chute 31 is provided on the side of the second arc plate 3 facing the main shaft 13, and both ends of the guide chute 31 pass through both sides of the second arc plate 3, and the guide chute 31 faces the discharge port 17;

[0052] By providing the guide chute 31 on the second curved plate 3, when the stirring plate 16 passes through the second curved plate 3, the coolant will generate an inclined flow due to the setting of the guide chute 31, and at the same time, a part of the coolant that impacts the second curved plate 3 will be reflected back to the polishing pad 4 through the guide chute 31, thereby effectively improving the polishing effect of the material;

[0053] When the coolant flows obliquely, the cooled material will approach the discharge port 17. Since the external water pump will continue to pump the coolant into the housing 1 and flow out from the discharge port 17, the material will be discharged from the discharge port 17 and then completed through subsequent spinning and drying.

[0054] Example 4: Reference Figure 4 , a water ring pelletizing mechanism for masterbatch production, which is basically the same as that of Example 3, and furthermore: an impact tube 161 is fixedly connected to one surface of the stirring plate 16, and the opening end of the impact tube 161 faces the extrusion die 11;

[0055] A plurality of beveled tubes 162 are fixedly connected to the impact tube 161 and are connected to the impact tube 161. The beveled tubes 162 extend to the other side of the stirring plate 16.

[0056] When the stirring plate 16 rotates with the main shaft 13, one side of the stirring plate 16 contacts the coolant, so that the water pressure on one side of the stirring plate 16 increases. At this time, the coolant enters the impact tube 161 through the bevel tube 162 and is discharged from the open end of the impact tube 161. The impact tube 161 is aligned with the extrusion die 11. This allows the cutter 154 to cut and separate the material. The coolant with a certain pressure discharged from the impact tube 161 can quickly disperse the cut and separated material to avoid accumulation.

[0057] In addition, since the forming holes 12 are clustered, the heat of the material that has not been cut is easily concentrated during the extrusion process. Therefore, the coolant discharged from the impact tube 161 can also cool the material that has not been cut, further improving the cooling effect on the material.

[0058] Example 5: Reference Figure 1-Figure 8 A method for producing masterbatch pellets mainly comprises the following steps:

[0059] S1, the main shaft 13 drives the cutter 154 to cut the material extruded from the extrusion die 11, and when the main shaft 13 rotates, the stirring plate 16 drives the coolant in the housing 1 to rotate, so that the coolant in the housing 1 flows;

[0060] S2, the cut material passes through the first curved plate 2, the second curved plate 3, and the stirring plate 16, so that the material contacts the polishing pad 4 for polishing;

[0061] S3, and the coolant in the housing 1 flows to the discharge port 17 through the guide chute 31, and the cooled material is discharged through the discharge port 17 for subsequent operations.

[0062] The present invention innovatively allows the forming hole 12 of the extrusion die 11 to be passed into the coolant, so that the material can be immediately cooled during the extrusion process, thereby accelerating the cooling effect, thereby avoiding the wire drawing phenomenon caused by the viscosity of the material during cutting;

[0063] In addition, by providing the first curved plate 2, the second curved plate 3, and the stirring plate 16, the cooling path of the cut material can be effectively extended, so that the flow path of the material in the housing 1 is increased, thereby accelerating the cooling effect of the material;

[0064] When the stirring plate 16 rotates and passes through the second curved plate 3, the coolant and a part of the material are hit on the second curved plate 3, and a part of the material rotates around the main shaft 13. The coolant and the material hitting the second curved plate 3 will flow to the first curved plate 2 close to the second curved plate 3 after being blocked by the second curved plate 3. A polishing pad 4 is provided in the angle between the first curved plate 2 and the housing 1, so a part of the material will contact the polishing pad 4 to polish the material and reduce the presence of burrs on the material.

[0065] By providing the guide chute 31 on the second curved plate 3, when the stirring plate 16 passes through the second curved plate 3, the coolant will generate an inclined flow due to the setting of the guide chute 31, and at the same time, a part of the coolant that impacts the second curved plate 3 will be reflected back to the polishing pad 4 through the guide chute 31, thereby effectively improving the polishing effect of the material;

[0066] When the coolant flows obliquely, the cooled material will approach the discharge port 17. Since the external water pump will continue to pump the coolant into the housing 1 and flow out from the discharge port 17, the material will be discharged from the discharge port 17, and then the material will be dried and dried to complete the production.

[0067] When the stirring plate 16 rotates with the main shaft 13, one side of the stirring plate 16 contacts the coolant, so that the water pressure on one side of the stirring plate 16 increases. At this time, the coolant enters the impact tube 161 through the bevel tube 162 and is discharged from the open end of the impact tube 161. The impact tube 161 is aligned with the extrusion die 11. This allows the cutter 154 to cut and separate the material. The coolant with a certain pressure discharged from the impact tube 161 can quickly disperse the cut and separated material to avoid accumulation.

[0068] In addition, since the forming holes 12 are clustered, the heat of the material that has not been cut is easily concentrated during the extrusion process. Therefore, the coolant discharged from the impact tube 161 can also cool the material that has not been cut, further improving the cooling effect on the material.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the present invention can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
