Description

Technical Field

[0001] The utility model belongs to the technical field of masterbatch production, and particularly relates to a lifting device for conveying black masterbatch. Background Art

[0002] The full name of the masterbatch is color masterbatch, also called colorant, which is a new type of special coloring agent for polymer materials, also known as pigment preparation. The masterbatch consists of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly loading an excessive amount of pigment into the resin, and can be called pigment concentrate. Therefore, its coloring power is higher than that of the pigment itself. During processing, a small amount of masterbatch is blended with uncolored resin to obtain a colored resin or product with the designed pigment concentration, which is mainly used in plastics.

[0003] The black masterbatch is a kind of masterbatch, but its status is different from that of other masterbatches. The black masterbatch is the most commonly used and the largest amount of masterbatch in plastic processing. The black masterbatch is a plastic colorant formed by well-dispersing a high proportion of pigment or additive and thermoplastic resin. The selected resin has good wetting and dispersing effects on the colorant and good compatibility with the material to be colored. During the plastic processing, the addition ratio of the black masterbatch needs to be accurately controlled to avoid serious color difference problems in the produced plastic products.

[0004] The Chinese utility model patent with the publication number of CN220576378U discloses a lifting device for conveying high-concentration black masterbatch, including a lifting barrel. One side of the upper surface of the lifting barrel is connected to the discharge port of the extrusion device through a feed pipe. A spiral groove is arranged on the inner side wall of the lifting barrel from bottom to top. A lifting plug is movably installed in the lifting barrel through the spiral groove. A spiral protrusion is integrally formed on the outer side of the lifting plug, and the spiral protrusion meshes with the spiral groove. A support plate is fixedly installed below the outer side of the lifting barrel through a support frame. A lifting cylinder is fixedly installed at the middle position above the support plate. The telescopic rod of the lifting cylinder is movably installed in the lower end of the lifting plug through a bearing. The lifting cylinder drives the lifting plug to rotate and lift up and down in the lifting barrel. A discharge pipe is inserted at one place above the outer side of the lifting barrel. The inside of the lifting barrel is a negative pressure barrel. The utility model directly lifts and doses the black masterbatch by means of negative pressure and spiral lifting, improving the accuracy and controllability of the black masterbatch ratio.

[0005] However, the above-mentioned utility model patent still has some deficiencies:

[0006] During the use of the above-mentioned utility model patent, the lifting cylinder drives the lifting plug to rotate up and down in the lifting barrel, so that the masterbatch enters the production equipment of plastic products from the discharge pipe. During this process, the precise control of the masterbatch during lifting, sealing and feeding is achieved by controlling the number of rotation circles of the spiral protrusions of the lifting plug. The top of the lifting plug is set as an inclined surface, which requires the lower part of the inclined surface of the lifting plug to face the discharge pipe after rotation to ensure that the masterbatch can roll down from the inclined surface of the lifting plug and enter the discharge pipe. Therefore, each time the lifting plug needs to rotate a complete number of circles, so that the lifting plug cannot accurately control the feeding of the color masterbatch when rotating a non-integer number of circles. Utility Model Content

[0007] The utility model provides a lifting device for masterbatch transportation, aiming to solve the problems mentioned in the above background technology.

[0008] The utility model is realized as follows: A lifting device for masterbatch transportation includes a storage tank. The bottom of the storage tank is fixedly connected with support legs. A cylinder is installed directly below the bottom of the storage tank. The telescopic end of the cylinder penetrates the bottom of the storage tank and extends into the interior of the storage tank and is fixedly connected with a lifting plate. A pressure sensor is installed on the top of the lifting plate. The top of the storage tank is fixedly connected with an installation box, and a material transportation component is installed in the installation box; in this solution, the pressure sensor monitors the weight of the masterbatch on the lifting plate in real time; the material transportation component transports the masterbatch on the lifting plate in sections.

[0009] Preferably, the material transportation component includes transmission rollers. The transmission rollers are arranged parallel to each other on the left and right in the installation box, and both end faces of the transmission rollers are rotatably installed on the side walls of the installation box through connecting rods. A conveyor belt is connected to the side wall of the transmission roller, and several material transportation plates are fixedly connected to the side wall of the conveyor belt; in this solution, the transmission rollers rotate to drive the conveyor belt to drive the material transportation plates to transport the masterbatch.

[0010] Preferably, one of the connecting rods penetrates the side wall of the installation box and is connected to the output shaft end of a motor. The motor is installed on the side wall of the installation box. A control display is installed on the outer wall of the storage tank. The motor and the pressure sensor are both connected to the control display through wireless signals; in this solution, the pressure sensor controls the motor through the control display according to the weight of the masterbatch to achieve quantitative transportation of the masterbatch.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The pressure sensor monitors the weight of the black masterbatch on the lifting plate in real time. When the reduced weight of the black masterbatch on the lifting plate reaches the set value, the control display controls the motor to stop working, so that the material conveying plate stops transporting the black masterbatch, and the quantitative conveying of the black masterbatch is completed.

[0015] When the telescopic end of the air cylinder controls the lifting plate to drive the black masterbatch to move upward, the material conveying plate gradually inserts into the black masterbatch, separating the black masterbatch into segments. When the material conveying plate rotates and conveys the black masterbatch, the black masterbatch between adjacent material conveying plates can be transported in segments, further accurately controlling the addition of the black masterbatch.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] Please refer to Figures 1-3 , the present utility model provides a technical solution: a lifting device for black masterbatch conveying, including a storage bin 1, a support leg 2 is fixedly connected to the bottom of the storage bin 1, a cylinder 4 is installed directly below the bottom of the storage bin 1, the telescopic end of the cylinder 4 penetrates through the bottom of the storage bin 1 and extends into the interior of the storage bin 1 and is fixedly connected to a lifting plate 5, a pressure sensor 6 is installed on the top of the lifting plate 5, and an installation box 3 is fixedly connected to the top of the storage bin 1, and a material conveying assembly 8 is installed in the installation box 3.

[0027] Specifically, the storage bin 1 is used to store and place black masterbatch. When the black masterbatch is fed into the storage bin 1, it falls on the lifting plate 5, and the weight of the black masterbatch is monitored in real time through the pressure sensor 6; when it is necessary to add black masterbatch to the production equipment of plastic products, the telescopic end of the cylinder 4 controls the lifting plate 5 to move upward, and the black masterbatch on the lifting plate 5 gradually rises and is conveyed under the action of the material conveying assembly 8. During this process, the pressure sensor 6 accurately controls the weight of the black masterbatch.

[0028] Further, the material conveying assembly 8 includes a conveying roller 81, which is arranged horizontally and oppositely on the left and right in the installation box 3, and both end faces of the conveying roller 81 are rotatably installed on the side wall of the installation box 3 through a connecting rod 82. A conveyor belt 83 is connected to the side wall of the conveying roller 81, and several material conveying plates 84 are fixedly connected to the side wall of the conveyor belt 83.

[0029] Specifically, when the conveying roller 81 rotates, it drives the conveyor belt 83 to transmit, and the conveyor belt 83 drives several material conveying plates 84 to rotate and convey in the vertical direction. During this process, the material conveying plates 84 convey the black masterbatch on the lifting plate 5.

[0030] The telescopic end of the air cylinder 4 drives the lifting plate 5 and the black masterbatch to move upward. When the black masterbatch moves to the top of the storage bin 1, the material conveying plates 84 gradually insert into the black masterbatch, separating the black masterbatch into segments, so that during the process of the material conveying plates 84 rotating and conveying, the black masterbatch between adjacent material conveying plates 84 can be transported in segments, further controlling the addition of the black masterbatch.

[0031] Further, one of the connecting rods 82 penetrates through the side wall of the installation box 3 and is connected to the output shaft end of the motor 85. The motor 85 is installed on the side wall of the installation box 3. A control display 7 is installed on the outer wall of the storage bin 1. The motor 85 and the pressure sensor 6 are both connected to the control display 7 through wireless signals.

[0032] Specifically, the motor 85 controls the corresponding connecting rod 82 to drive the conveying roller 81 to rotate, so that the conveyor belt 83 drives the material conveying plates 84 to rotate and convey.

[0033] The weight of the black masterbatch on the lifting plate 5 monitored by the pressure sensor 6 is transmitted to the control display 7 in real time. When the reduced weight of the black masterbatch on the lifting plate 5 reaches the set value, the control display 7 controls the motor 85 to stop working, causing the material conveying to be interrupted.

[0034] Further, a feed hopper 10 is installed at the leftmost position on the top of the installation box 3. A sloping block 9 is fixedly connected to the inner wall of the installation box 3 directly below the feed hopper 10, and the sloping block 9 slopes towards the storage space of the storage bin 1.

[0035] Specifically, the black masterbatch to be stored enters the installation box 3 from the feed hopper 10. During this process, the material conveying assembly 8 operates, and the black masterbatch rolls along the inclined plane into the storage bin 1 and lands on the lifting plate 5.

[0036] Further, a material guiding area 11 is arranged at the rightmost side in the installation box 3. Material guiding plates 12 are arranged oppositely and obliquely in the front and back in the material guiding area 11. The material guiding plates 12 are fixedly connected to the inner wall of the installation box 3. A discharge pipe 13 is arranged at the lowest point of the inclined plane of the material guiding plates 12 and at the bottom of the installation box 3. The outlet end of the discharge pipe 13 is connected to the production equipment of plastic products.

[0037] Specifically, the material guiding plate 12 is inclined towards the discharge pipe 13; the black masterbatch enters the material guiding area 11 under the rotational transportation of the material guiding plate 12 and lands on the material guiding plate 12, and then the black masterbatch enters the discharge pipe 13 along the material guiding plate 12 and enters the production equipment of the plastic product.

[0038] Working principle and usage process of the present utility model: After the present utility model is installed, the black masterbatch enters the storage box 1 through the feed hopper 10 for storage. When it is necessary to convey the black masterbatch to the production equipment of the plastic product, the telescopic end of the cylinder 4 controls the lifting plate 5 to drive the black masterbatch to move upward;

[0039] In the above process, the motor 85 controls the corresponding connecting rod 82 to drive the conveying roller 81 to rotate, so that the conveyor belt 83 drives the material conveying plate 84 to rotate and convey in the vertical direction. The black masterbatch enters the material guiding area 11 under the material conveying action of the material conveying plate 84 and lands on the material guiding plate 12, and then enters the discharge pipe 13 along the material guiding plate 12 and enters the production equipment of the plastic product;

[0040] During the above process of conveying the black masterbatch, the pressure sensor 6 monitors the weight of the black masterbatch on the lifting plate 5 in real time. When it is monitored that the weight of the black masterbatch reduced on the lifting plate 5 reaches the set value, the control display 7 controls the motor 85 to stop working, so that the material conveying is interrupted, and the quantitative conveying of the black masterbatch is completed.

[0041] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
