Description

Technical Field

[0001] The invention belongs to the technical field of coloring devices, and in particular relates to a rapid coloring device for PA66 stock solution. Background Art

[0002] PA66 (polyhexamethylene adipamide) is a thermoplastic resin, also known as polyamide. It has the characteristics of wear resistance, high strength, high temperature resistance, and oil resistance. It is widely used in the fields of automobiles, electronics, electrical appliances, and machinery manufacturing.

[0003] PA66 stock solution is the abbreviation of polyhexamethylene adipamide, commonly known as nylon-66. It is a translucent or opaque milky white solid with high mechanical strength, heat resistance, excellent impact resistance, self-lubrication, wear resistance and chemical corrosion resistance. In addition, PA66 has good fatigue resistance, aging resistance, flame retardancy and non-toxic and environmentally friendly properties, and is widely used in automobile manufacturing, machinery manufacturing, chemical equipment, aerospace and other fields. The production process of PA66 stock solution includes polymerization, spinning and post-treatment processes, among which polymerization is the key link in the preparation of PA66 stock solution. During the polymerization process, hexamethylenediamine and adipic acid react under the action of a catalyst to generate oligomers, and then through hydrogenation, catalyst addition, chain extender addition and other processes, PA66 stock solution is finally prepared. PA66 stock solution is an important engineering plastic with broad application prospects. With the continuous development of industry and technology, PA66 stock solution has important application value in many fields, and its production technology and market prospects will also be further developed.

[0004] The rapid coloring device for PA66 stock solution is a device used to quickly and evenly add masterbatch to PA66 stock solution. This device can improve production efficiency and product quality, and can reduce manual operation and errors. The device is usually composed of a storage hopper, an agitator, a metering pump, a mixer and a conveying pipeline. When using the device, first add the masterbatch to the storage hopper, stir it evenly with the agitator, then control the amount of masterbatch added by the metering pump, and convey the masterbatch and PA66 stock solution to the mixer through the conveying pipeline for mixing, and finally convey the mixed PA66 stock solution to the next process through the conveying pipeline.

[0005] Since the rapid coloring device for PA66 stock solution usually uses masterbatch as the colorant, and the quality of the masterbatch needs to be ensured when it is used to ensure the quality and performance of the final product, the quality of the masterbatch needs to be checked before it is used. The current storage hopper is inconvenient to check the quality of the masterbatch after the masterbatch is put in, resulting in low inspection efficiency. Summary of the invention

[0006] The object of the present invention is to provide a rapid coloring device for PA66 stock solution to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: a rapid coloring device for PA66 stock solution, comprising a storage tank, a tank cover is installed at the top of the storage tank, a feed port is installed inside the tank cover, a support seat is fixedly installed at the bottom of the storage tank, a stirring assembly and an inspection assembly are arranged inside the storage tank, a discharge assembly is arranged at the bottom of the storage tank, a mixing tank is arranged on one side of the storage tank, a first conveying pipeline is connected between the storage tank and the mixing tank, and a second conveying pipeline is installed on one side of the mixing tank;

[0009] When the PA66 stock solution needs to be quickly colored, the required masterbatch is first added into the storage tank through the feed port, and then the first motor is started by controlling the PLC. The start of the first motor drives the rotation of the stirring shaft, and the rotation of the stirring shaft drives the rotation of the stirring blade, so that the stirring blade mixes the masterbatch in the storage tank.

[0010] After the mixing is completed, it is discharged into the interior of the mixing tank through the first conveying pipe, and the masterbatch is mixed with the PA66 stock solution through the mixing tank. The mixed PA66 stock solution is conveyed to the next process through the second conveying pipe.

[0011] The inspection component includes a sampling box arranged inside the material storage tank, the sampling box is slidably connected to the material storage tank, a handle is fixedly installed on one side of the sampling box, a material baffle plate is slidably installed on the top of the sampling box, a discharge port is arranged on the top of the material baffle plate, the discharge port is opened inside the material storage tank, a fixed block is fixedly installed on one side of the material baffle plate, a protrusion is arranged on one side of the fixed block, the protrusion is installed on the top of the sampling box, and a baffle is arranged on one side of the sampling box.

[0012] When it is necessary to check the status of the masterbatch inside the storage tank, first pull the handle, the movement of the handle drives the movement of the sampling box, the movement of the sampling box drives the movement of the protrusion, one side of the fixed block is set to an inclined setting, the protrusion moves and contacts with it, drives the fixed block to move to one side, the movement of the fixed block drives the movement of the baffle plate, and the discharge port is opened. The masterbatch inside the storage tank falls from the discharge port to the inside of the sampling box. After the sampling box is completely pulled out of the storage tank, the status of the masterbatch inside the storage tank can be observed, which avoids the inconvenience of quality inspection of the masterbatch after the masterbatch is put into the current storage hopper, resulting in low inspection efficiency, improves the inspection efficiency of the masterbatch inside the storage tank, and ensures the quality of the masterbatch.

[0013] As a further technical solution of the present invention, the material baffle plate is slidably installed inside the material storage tank, and a second spring is provided on one side of the material baffle plate.

[0014] When the baffle plate moves inside the storage tank, the baffle plate squeezes the second spring to deform it and store elastic potential energy. When the protrusion is separated from the fixed block, the elastic potential energy is released by the second spring to drive the baffle plate to reset and close the discharge port, ensuring that the masterbatch falls into the sampling box.

[0015] As a further technical solution of the present invention, the top end of the protrusion is inclined.

[0016] When the inspection is completed and the sampling box needs to be installed back into the storage tank, the sampling box is embedded in the storage tank and slid inward. Similarly, the movement of the sampling box drives the movement of the protrusion, the inclined surface of the protrusion contacts the fixed block, and the protrusion slides into the interior of the sampling box, so that the sampling box will not fall out when placed in the storage tank, thereby ensuring the stability of the device.

[0017] As a further technical solution of the present invention, a first limit plate is fixedly installed at the bottom end of the protrusion, the first limit plate is slidably installed inside the sampling box, and a first spring is arranged at the bottom end of the first limit plate.

[0018] As a further technical solution of the present invention, an observation window is provided on one side of the storage tank.

[0019] The state of the masterbatch in the storage tank can be observed to prevent its quality from changing and affecting the quality and performance of the final product. When the quality of the masterbatch changes, it is convenient to handle it in time to ensure the quality of the product.

[0020] As a further technical solution of the present invention, the discharge assembly includes a ball valve arranged at the bottom end of the storage tank, and rotating shafts are fixedly installed on both sides of the ball valve. Both rotating shafts are rotatably installed inside the storage tank, and a discharge assembly is arranged at one end of one of the rotating shafts, and a second motor is fixedly installed at one end of the other rotating shaft.

[0021] When the masterbatch inside the storage tank is mixed, the second motor can be started by PLC control. The start of the second motor drives the rotation of the rotating shaft, and the rotation of the rotating shaft drives the rotation of the ball valve, so that the masterbatch mixed inside the storage tank is discharged from the storage tank into the first conveying pipe, which is convenient for discharging after the masterbatch mixing is completed.

[0022] As a further technical solution of the present invention, the discharge assembly includes a gear fixedly mounted on one end of a rotating shaft, the top end of the gear is meshedly connected with a rack plate, a moving rod is provided at one end of the rack plate, the moving rod is fixedly mounted on one side of a baffle, a discharge trough is provided below the baffle, and the discharge trough is opened inside the storage tank.

[0023] When the ball valve rotates to discharge materials, the rotation of the ball valve drives the rotation of the rotating shaft, the rotation of the rotating shaft drives the rotation of the gear, the rotation of the gear drives the movement of the rack plate, the end of the rack plate close to the moving rod is set as an inclined surface, the inclined surface of the rack plate contacts the moving rod and drives the moving rod to move, the movement of the moving rod drives the movement of the baffle plate, so that the baffle plate moves to the side away from the sampling box and separates from the sampling box, and the masterbatch inside the sampling box is discharged from the inside of the sampling box.

[0024] As a further technical solution of the present invention, one side of the baffle is fixedly connected to a connecting rod, one end of the connecting rod is fixedly connected to a second limiting plate, the second limiting plate is slidably installed inside the sampling box, and a third spring is arranged on one side of the second limiting plate.

[0025] When the baffle moves to the side away from the sampling box, the movement of the sampling box drives the movement of the connecting rod, and the connecting rod slides inside the sampling box. The movement of the connecting rod drives the movement of the second limit plate, and the second limit plate squeezes the third spring to deform the third spring, thereby storing elastic potential energy.

[0026] When the discharging is completed, the rotating shaft rotates, the rack plate separates from the moving rod, and the elastic potential energy is released by the third spring to reset the baffle, and one side of the baffle fits with the sampling box to facilitate material storage.

[0027] As a further technical solution of the present invention, the ventilation assembly includes a ventilation hole opened inside the tank cover, a connecting shaft is rotatably installed inside the ventilation hole, a ventilation fan is fixedly installed on the outer wall of the connecting shaft, and a pulley is connected to the bottom end of the connecting shaft, and the outer wall of the stirring shaft is installed on the pulley.

[0028] When the masterbatch is stirred, the rotation of the stirring shaft drives the rotation of the connecting shaft through the pulley, and the rotation of the connecting shaft drives the rotation of the ventilation fan to ventilate the interior of the storage tank. Since the masterbatch is hygroscopic and easily gets damp and deteriorates, ventilation can reduce the humidity of the air, thereby preventing the masterbatch from getting damp and ensuring its stable quality and performance.

[0029] As a further technical solution of the present invention, baffles are installed inside the ventilation holes, and the baffles are evenly distributed in a ring array.

[0030] When the ventilation fan is not rotating, the baffle is closed to prevent dust from being adsorbed on the surface of the masterbatch, causing quality changes, thereby ensuring the stability of the masterbatch quality.

[0031] The beneficial effects of the present invention are as follows:

[0032] 1. The present invention sets an inspection component. When it is necessary to check the state of the masterbatch inside the storage tank, the handle is first pulled, and the movement of the handle drives the movement of the sampling box, and the movement of the sampling box drives the movement of the protrusion. One side of the fixed block is set to be inclined, and the movement of the protrusion and the contact with it drive the fixed block to move to one side, and the movement of the fixed block drives the movement of the baffle plate to open the discharge port, and the masterbatch inside the storage tank falls from the discharge port to the inside of the sampling box. After the sampling box is completely pulled out of the storage tank, the state of the masterbatch inside the storage tank can be observed, which avoids the problem of inconvenience in quality inspection of the masterbatch after the masterbatch is put in the current storage hopper, resulting in low inspection efficiency, improves the inspection efficiency of the masterbatch inside the storage tank, and ensures the quality of the masterbatch.

[0033] 2. The present invention arranges a discharge assembly. When the ball valve rotates to discharge material, the rotation of the ball valve drives the rotation of the rotating shaft, the rotation of the rotating shaft drives the rotation of the gear, the rotation of the gear drives the movement of the rack plate, the end of the rack plate close to the moving rod is arranged as an inclined surface, the inclined surface of the rack plate contacts the moving rod and drives the moving rod to move, the movement of the moving rod drives the movement of the baffle plate, so that the baffle plate moves to the side away from the sampling box and separates from the sampling box, and the masterbatch inside the sampling box is discharged from the inside of the sampling box. If the masterbatch inside the sampling box is still a qualified product after inspection, the sampling box can be directly pushed into the storage tank, and finally discharged into the first conveying pipeline through the discharge assembly, so as to prevent waste of material.

[0034] 3. The present invention provides a ventilation component. When the masterbatch is stirred, the rotation of the stirring shaft drives the rotation of the connecting shaft through the pulley, and the rotation of the connecting shaft drives the rotation of the ventilation fan to ventilate the interior of the storage tank. Since the masterbatch is hygroscopic and easily gets damp and deteriorates, ventilation can reduce the humidity of the air, thereby preventing the masterbatch from getting damp and ensuring the stability of its quality and performance.

[0051] The inspection component includes a sampling box 20 arranged inside the storage tank 1, the sampling box 20 is slidably connected to the storage tank 1, a handle 21 is fixedly installed on one side of the sampling box 20, a baffle plate 27 is slidably installed on the top of the sampling box 20, a discharge port 29 is arranged on the top of the baffle plate 27, and the discharge port 29 is opened inside the storage tank 1, a fixed block 26 is fixedly installed on one side of the baffle plate 27, a protrusion 23 is arranged on one side of the fixed block 26, the protrusion 23 is installed on the top of the sampling box 20, and a baffle 22 is arranged on one side of the sampling box 20.

[0052] By checking the setting of the component, when it is necessary to check the state of the masterbatch inside the storage tank 1, first pull the handle 21, the movement of the handle 21 drives the movement of the sampling box 20, the movement of the sampling box 20 drives the movement of the protrusion 23, one side of the fixed block 26 is set to be inclined, the protrusion 23 moves and contacts with it, drives the fixed block 26 to move to one side, the movement of the fixed block 26 drives the movement of the baffle plate 27, and the discharge port 29 is opened, and the masterbatch inside the storage tank 1 falls from the discharge port 29 to the inside of the sampling box 20. After the sampling box 20 is completely pulled out of the storage tank 1, the state of the masterbatch inside the storage tank 1 can be observed, which avoids the inconvenience of quality inspection of the masterbatch after the masterbatch is put into the current storage hopper, resulting in low inspection efficiency, improves the inspection efficiency of the masterbatch inside the storage tank 1, and ensures the quality of the masterbatch.

[0053] like Figure 7 As shown, the baffle plate 27 is slidably installed inside the material storage tank 1 , and a second spring 28 is provided on one side of the baffle plate 27 .

[0054] When the baffle plate 27 moves inside the storage tank 1, the baffle plate 27 squeezes the second spring 28 to deform the second spring 28 to store elastic potential energy. When the protrusion 23 is separated from the fixed block 26, the elastic potential energy is released by the second spring 28 to drive the baffle plate 27 to reset and close the discharge port 29 to ensure that the masterbatch falls into the interior of the sampling box 20.

[0055] like Figures 1 to 11 As shown, the top end of the projection 23 is inclined.

[0056] When the inspection is completed and the sampling box 20 needs to be installed back into the storage tank 1, the sampling box 20 is embedded in the storage tank 1 and slides inward. Similarly, the movement of the sampling box 20 drives the movement of the protrusion 23. The inclined surface of the protrusion 23 contacts the fixed block 26, and the protrusion 23 slides into the interior of the sampling box 20, so that the sampling box 20 will not fall out when placed in the storage tank 1, thereby ensuring the stability of the device.

[0058] When the protrusion 23 slides into the sampling box 20, the movement of the protrusion 23 squeezes the first spring 25, causing the first spring 25 to deform and store elastic potential energy. When the sampling box 20 completely slides into the storage tank 1, the protrusion 23 separates from the fixed block 26, and the first spring 25 releases the elastic potential energy to reset the protrusion 23 for easy reuse.

[0059] like Figure 1 , Figure 2 and Figure 3 As shown, an observation window 11 is provided on one side of the storage tank 1 .

[0060] The state of the masterbatch in the storage tank 1 can be observed to prevent its quality from changing and affecting the quality and performance of the final product, so that when the quality of the masterbatch changes, it can be handled in time to ensure the quality of the product.

[0061] like Figures 1 to 11 As shown, the discharge assembly includes a ball valve 17 arranged at the bottom end of the storage tank 1, and rotating shafts 18 are fixedly installed on both sides of the ball valve 17. The two rotating shafts 18 are rotatably installed inside the storage tank 1, and a discharge assembly is arranged at one end of one of the rotating shafts 18, and a second motor 19 is fixedly installed at one end of the other rotating shaft 18.

[0062] Through the setting of the discharging component, when the masterbatch inside the storage tank 1 is mixed, the second motor 19 can be started by PLC control. The start of the second motor 19 drives the rotation of the rotating shaft 18, and the rotation of the rotating shaft 18 drives the rotation of the ball valve 17, so that the masterbatch mixed inside the storage tank 1 is discharged from the storage tank 1 into the first conveying pipe 4, which is convenient for discharging after the masterbatch mixing is completed.

[0063] like Figures 1 to 11 As shown, the discharge assembly includes a gear 36 fixedly mounted on one end of the rotating shaft 18, the top end of the gear 36 is meshedly connected with a rack plate 30, a moving rod 31 is provided at one end of the rack plate 30, the moving rod 31 is fixedly mounted on one side of the baffle 22, a discharge trough 32 is provided below the baffle 22, and the discharge trough 32 is opened inside the storage tank 1.

[0064] Through the setting of the discharge assembly, when the ball valve 17 rotates to discharge, the rotation of the ball valve 17 drives the rotation of the rotating shaft 18, the rotation of the rotating shaft 18 drives the rotation of the gear 36, the rotation of the gear 36 drives the movement of the rack plate 30, the end of the rack plate 30 close to the moving rod 31 is set as an inclined surface, the inclined surface of the rack plate 30 contacts the moving rod 31 to drive the moving rod 31 to move, the movement of the moving rod 31 drives the movement of the baffle 22, so that the baffle 22 moves to the side away from the sampling box 20, separates from the sampling box 20, and the masterbatch inside the sampling box 20 is discharged from the inside of the sampling box 20;

[0065] The bottom of the sampling box 20 is tilted to facilitate the discharge of the masterbatch inside the sampling box 20;

[0066] A discharge trough 32 is provided inside the storage tank 1. When the masterbatch in the sampling box 20 is discharged, the masterbatch can be discharged into the first conveying pipe 4 through the guidance of the discharge trough 32.

[0067] If the masterbatch in the sampling box 20 is still qualified after inspection, the sampling box 20 can be directly pushed into the storage tank 1 and finally discharged into the first conveying pipe 4 through the discharge assembly, thereby preventing waste of materials.

[0068] like Fig.10 and Fig.11 As shown, a connecting rod 33 is fixedly connected to one side of the baffle 22, and a second limiting plate 34 is fixedly connected to one end of the connecting rod 33. The second limiting plate 34 is slidably installed inside the sampling box 20, and a third spring 35 is arranged on one side of the second limiting plate 34.

[0069] When the baffle 22 moves to the side away from the sampling box 20, the movement of the sampling box 20 drives the movement of the connecting rod 33, and the connecting rod 33 slides inside the sampling box 20. The movement of the connecting rod 33 drives the movement of the second limiting plate 34, and the second limiting plate 34 squeezes the third spring 35 to deform the third spring 35, thereby storing elastic potential energy.

[0070] When the rotating shaft 18 rotates after the material is discharged, the rack plate 30 is separated from the moving rod 31, and the elastic potential energy is released by the third spring 35 to reset the baffle 22, and one side of the baffle 22 is in contact with the sampling box 20 for easy material storage.

[0071] Embodiment 2

[0072] like Figures 1 to 11 As shown, in the embodiment of the present invention, the ventilation assembly includes a ventilation hole 15 opened inside the tank cover 2, a connecting shaft 14 is rotatably installed inside the ventilation hole 15, a ventilation fan 13 is fixedly installed on the outer wall of the connecting shaft 14, and a pulley 12 is connected to the bottom end of the connecting shaft 14, and the outer wall of the stirring shaft 8 is installed on the pulley 12.

[0073] Through the setting of the ventilation component, when the masterbatch is stirred, the rotation of the stirring shaft 8 drives the rotation of the connecting shaft 14 through the pulley 12, and the rotation of the connecting shaft 14 drives the rotation of the ventilation fan 13 to ventilate the interior of the storage tank 1. Since the masterbatch is hygroscopic and easily gets damp and deteriorates, ventilation can reduce the humidity of the air, thereby preventing the masterbatch from getting damp and ensuring the stability of its quality and performance.

[0074] like Figures 1 to 4 As shown, baffles 16 are installed inside the ventilation hole 15, and the baffles 16 are evenly distributed in a ring array.

[0075] When the ventilation fan 13 is not rotating, the baffle 16 is closed to prevent dust from being adsorbed on the surface of the masterbatch, causing the quality to change, thereby ensuring the stability of the masterbatch quality;

[0076] The baffle 16 is made of elastic material, and the outer wall of the baffle 16 is fixedly connected to the vent 15. When the ventilating fan 13 rotates, the baffle 16 is blown open to facilitate ventilation.

[0077] Like rubber, rubber has excellent elasticity and flexibility. It can be deformed under external force and quickly return to its original shape after the external force is removed.

[0078] Working principle and usage process:

[0079] When the PA66 stock solution needs to be quickly colored, the required masterbatch is first added into the storage tank 1 through the feed port 10, and then the first motor 7 is started by the PLC control, and the start of the first motor 7 drives the rotation of the stirring shaft 8, and the rotation of the stirring shaft 8 drives the rotation of the stirring blade 9, so that the stirring blade 9 mixes the masterbatch in the storage tank 1;

[0080] At the same time, the rotation of the stirring shaft 8 drives the rotation of the connecting shaft 14 through the pulley 12, and the rotation of the connecting shaft 14 drives the rotation of the ventilation fan 13, so that the masterbatch is ventilated when it is mixed;

[0081] After the mixing is completed, the second motor 19 is started by PLC control, and the start of the second motor 19 drives the rotation of the rotating shaft 18, and the rotation of the rotating shaft 18 drives the rotation of the ball valve 17, so that the masterbatch mixed in the storage tank 1 is discharged from the storage tank 1 into the first conveying pipe 4, and then discharged into the mixing tank 5 through the first conveying pipe 4, and the masterbatch is mixed with the PA66 stock solution through the mixing tank 5, and the mixed PA66 stock solution is transported to the next process through the second conveying pipe 6.

[0082] When it is necessary to check the masterbatch inside the storage tank 1, first pull the handle 21 and move the sampling box 20 outward. The movement of the sampling box 20 drives the movement of the protrusion 23. When the protrusion 23 moves and contacts with the fixed block 26, it drives the fixed block 26 to slide to one side. The movement of the fixed block 26 drives the movement of the baffle plate 27, so that the baffle plate 27 opens the discharge port 29, and the masterbatch inside the storage tank 1 falls from the discharge port 29 to the inside of the sampling box 20. After the sampling box 20 is completely moved out of the storage tank 1, the state of the masterbatch inside the sampling box 20 is checked.

[0083] After the inspection is completed, the sampling box 20 is pushed into the storage tank 1. Similarly, the movement of the sampling box 20 drives the movement of the protrusion 23. When the protrusion 23 contacts the fixing block 26, the protrusion 23 slides into the interior of the sampling box 20, so that the sampling box 20 is completely embedded in the storage tank 1.

[0084] When the masterbatch mixing inside the storage tank 1 is completed and it is discharged, the rotation of the rotating shaft 18 drives the rotation of the gear 36, and the rotation of the gear 36 drives the movement of the rack plate 30. The rack plate 30 contacts the moving rod 31 and drives the moving rod 31 to move to one side. The movement of the moving rod 31 drives the movement of the baffle 22 to separate the baffle 22 from the sampling box 20. The masterbatch inside the sampling box 20 slides out of the sampling box 20 and is discharged into the first conveying pipe 4 through the discharge chute 32 to prevent waste.

[0085] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
