[0002] Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. It is an aggregate obtained by uniformly attaching an extraordinary amount of pigment to the resin, which can be called pigment concentrate. Therefore, its coloring power is higher than the pigment itself. When processing, a small amount of masterbatch is mixed with uncolored resin to achieve the coloring resin or product with the designed pigment concentration.

[0016] like Figure 1-Figure 5 A conveying device for masterbatch production shown in the figure includes a conveying frame 1; in order to dry the surface of the masterbatch, a conveying assembly 2 is installed on the surface of the conveying frame 1, and the conveying assembly 2 includes a conveyor 21 fixed on one side of the surface of the conveying frame 1 and a conveyor 22 fixed on the other side of the surface of the conveying frame 1, and a screen 23 arranged obliquely between the conveyor 21 and the conveyor 22, there is a height difference between the conveyor 21 and the conveyor 22, and a drying box 24 is fixed on the side of the surface of the conveying frame 1 close to the screen 23, and a hot air blower 25 is fixed inside the drying box 24.

[0017] In this embodiment, the cut masterbatch will fall onto the surface of the screen 23 under the continuous conveyance of the conveyor 21. At this time, the hot air blower 25 can blow out hot air to dry the surface of the masterbatch, thereby quickly and effectively removing the coolant attached to the surface of the masterbatch to ensure the purity of the masterbatch.

[0018] In an optional embodiment: fixing ears 27 are fixed at the four corners of the surface of the screening net 23, a movable groove matched with the fixing ears 27 is opened inside the conveying frame 1, and the fixing ears 27 are slidably connected to the inside of the conveying frame 1 through the movable groove, a spring 28 is fixed between the fixing ears 27 and the conveying frame 1, a collecting box 26 is fixed inside the conveying frame 1 near the bottom of the screening net 23, a connecting frame 29 is fixed between the two groups of fixing ears 27, a shaking cam 210 is abutted in the middle of the surface of the connecting frame 29, a rotating shaft 211 is fixed between the two groups of shaking cams 210, and the rotating shaft 211 is rotatably connected to the inside of the conveying frame 1.

[0019] In this embodiment: with the cooperation of the transmission chain 212, the rotating shaft 211 can be driven to rotate inside the conveying frame 1, and then the shaking cams 210 at both ends can be driven to rotate synchronously. Then, under the action of the spring 28, not only the amplitude of the screening mesh 23 can be increased, but also the shaking cam 210 can be made close to the surface of the connecting frame 29, so that the connecting frame 29 drives the fixed ear 27 to slide back and forth in the movable groove starting from the inside of the conveying frame 1, which can drive the screening mesh 23 to shake back and forth inside the conveying frame 1, and the screened masterbatch will automatically fall on the surface of the conveyor 22 to complete further transportation.

[0020] It should be noted that: through the function of the sieve 23, the drying task is completed, and the masterbatch can be screened, and unqualified particles can be removed and dropped into the collection box 26 for collection, thereby improving product quality.

[0021] Going further: In combination with the above content, in order to cut the masterbatch strips into small particles of masterbatch, it also includes a cutting component 3 installed on the surface of the conveyor 21, the cutting component 3 includes a fixed frame 31 fixed on the surface of the conveyor 21 and support plates 32 fixed on both sides of the surface of the fixed frame 31 and a driving shaft 33 rotatably connected between the two groups of support plates 32, and push cams 35 are symmetrically fixed on both sides of the surface of the driving shaft 33, and push rods 310 are arranged under the two groups of push cams 35, and cutting knives 312 are arranged at the bottom ends of the two groups of push rods 310.

[0022] In this embodiment: the masterbatch strips after cooling and shaping are placed on the surface of a conveyor 21, and the masterbatch strips can be transported by the operation of the conveyor 21. During this period, by starting the drive motor 34, when the masterbatch strips are transported to the bottom of the cutting knife 312, the operation of the drive motor 34 can drive the drive shaft 33 to rotate between the two sets of support plates 32, thereby driving the push cam 35 to rotate synchronously. With the rotation of the push cam 35, the cutting knife 312 is driven to approach the surface of the masterbatch strips, and the masterbatch strips can be cut into small particles of masterbatch by cooperating with the transportation of the conveyor 21.

[0023] In an optional embodiment: a driving motor 34 is screwed to one side of the surface of the support plate 32, and the output end of the driving motor 34 is fixedly connected to one end of the driving shaft 33, and a transmission chain 212 is connected between the other end of the driving shaft 33 and one end of the rotating shaft 211 through a sprocket, a positioning push seat 36 is abutted on the surface of the push cam 35, a push frame 37 is fixed between the two groups of positioning push seats 36, a positioning column 38 is fixed to the side of the surface of the fixed frame 31 close to the push frame 37, and a positioning groove matching the positioning column 38 is provided inside the push frame 37, a spring 2 39 is wound around the surface of the positioning column 38, and the two ends of the spring 2 39 are fixed between the push frame 37 and the fixed frame 31, a push groove matching the push rod 310 is provided inside the fixed frame 31, a knife seat 311 is fixed between the bottom ends of the two groups of push rods 310, and a cutting knife 312 is screwed to the inside of the knife seat 311.

[0024] In this embodiment: as the push cam 35 rotates, under the action of spring 2 39, the positioning push seat 36 can be closely attached to its surface, and the positioning push seat 36 can be pushed up and down reciprocatingly, thereby driving the push frame 37 to slide up and down along the surfaces of the two groups of positioning columns 38. Through the movement of the push frame 37, the spring 2 39 can be squeezed to deform and generate elastic force, thereby driving the push rod 310 to slide in the push groove opened inside the fixed frame 31, thereby driving the knife seat 311 and the cutting knife 312 to approach the surface of the masterbatch strip, so as to cut the masterbatch strip into small particles of masterbatch, ensuring that the generated masterbatch particles are uniform in size.

[0025] The working principle and use process of the present invention are as follows: when it is necessary to transport the masterbatch, firstly, the masterbatch strips after cooling and finalization are placed on the surface of the conveyor 21, and the masterbatch strips can be transported by the operation of the conveyor 21. During this period, by starting the driving motor 34, when the masterbatch strips are transported to the bottom of the cutting knife 312, the operation of the driving motor 34 can drive the driving shaft 33 to rotate between the two groups of support plates 32, thereby driving the pushing cam 35 to rotate synchronously. With the rotation of the pushing cam 35, under the action of the spring 2 39, the positioning push seat 36 can be closely attached to its surface, and reciprocatingly push the positioning push seat 36 up and down, thereby driving the pushing frame 37 to slide up and down along the surfaces of the two groups of positioning columns 38. The movement of the push frame 37 can squeeze the spring 39 to deform and generate elastic force, thereby driving the push rod 310 to slide in the push groove opened inside the fixed frame 31, thereby driving the knife seat 311 and the cutting knife 312 to approach the surface of the masterbatch strip. With the transportation of the conveyor 21, the masterbatch strip can be cut into small particles of masterbatch. The cutting length of the masterbatch strip can be accurately controlled to ensure that the size of the generated masterbatch particles is uniform, improve the stability of product quality, and facilitate subsequent processing and use. Continuous operation can be achieved and the masterbatch strip can be quickly cut, which greatly improves the cutting efficiency of the masterbatch and reduces the production time, thereby increasing the speed of the entire production process and meeting the needs of large-scale production.

[0026] The cut masterbatch will fall onto the surface of the screen 23 under the continued conveyance of the conveyor 21. At this time, the hot air blower 25 can be operated to blow out hot air to dry the surface of the masterbatch, thereby quickly and effectively removing the coolant attached to the surface of the masterbatch to ensure the purity of the masterbatch, thereby ensuring the quality of the product in subsequent use, and timely removing the coolant can prevent the masterbatch from being contaminated in subsequent production links, making the masterbatch more stable during storage and transportation, and less prone to problems such as agglomeration and deterioration, thereby improving the performance and quality of the masterbatch. During this period, through the rotation of the drive shaft 33, with the cooperation of the transmission chain 212, the rotating shaft 211 can be driven to rotate inside the conveying frame 1, thereby driving the shaking cams 210 at both ends to rotate synchronously, and then under the action of the spring 28, not only the amplitude of the screen 23 can be increased, but also The shaking cam 210 is in close contact with the surface of the connecting frame 29, so that the connecting frame 29 drives the fixed ear 27 to slide back and forth in the movable groove starting from the inside of the conveying frame 1, and can drive the screening mesh 23 to shake back and forth inside the conveying frame 1, so that the masterbatch keeps jumping, increasing the contact area and contact frequency between the masterbatch and the hot air, further improving the drying effect, shortening the drying time, and improving the production efficiency. It also avoids the agglomeration or adhesion of the masterbatch due to the presence of the coolant, helps to disperse the masterbatch, prevents the masterbatch from piling up, and ensures the loose state of the masterbatch. Through the action of the screening mesh 23, the drying task is completed, and the masterbatch can be screened, unqualified particles are removed and fall into the collection box 26 for collection, thereby improving product quality. The screened masterbatch will automatically fall on the surface of the conveyor 22 to complete further transportation.

After reading the description, ordinary technicians in the relevant technical field can modify or deform the specific implementation modes described above without departing from the essence and scope of the invention.
