Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch cutting, in particular to a masterbatch cutting device. Background Art

[0002] Masterbatch is a new type of colorant specially used for polymer materials, mainly used in plastics. Masterbatch is composed of three basic elements: pigment or dye, carrier and additive. When masterbatch is first produced, it is in the form of strips and needs to be cut into granules for easy packaging and use.

[0003] At present, there are certain defects in the masterbatch cutting device. For example, the patent number "202120767713.6" proposes a cutting device for masterbatch production. The device controls the conveying mechanism to convey the masterbatch, so that the conveying mechanism controls the cutting mechanism through the transmission mechanism to cut the masterbatch conveyed to the fixed plate. However, the actual situation is that the masterbatch is in the form of strips. When cutting it, if it is placed directly on the conveyor belt and pushed forward, since it is not limited, the position of the masterbatch will be offset when the masterbatch is cut, thereby affecting the cutting accuracy during cutting. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a masterbatch cutting device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Preferably, the rotating mechanism includes a first transmission wheel and a second transmission wheel rotatably connected to the outside of the box body, and the first transmission wheel and the second transmission wheel are fixedly connected to the first rotating roller and the second rotating roller adjacent thereto, respectively.

[0008] Preferably, the first transmission wheel is connected to the second transmission wheel through a transmission belt, and two feed ports are provided on the outer wall of the box body, and the two feed ports are communicated with the interior of the box body.

[0009] Preferably, an expansion plate is fixedly connected to the outer wall of the box body, and a bracket is fixedly connected to the upper end of the expansion plate.

[0010] Preferably, the lower end of the bracket is fixedly connected to a hydraulic cylinder, the telescopic end of the hydraulic cylinder is fixedly connected to a blade, and the outer wall of the box is provided with a discharge port.

[0011] Preferably, a servo motor is fixedly connected to the outer wall of the box body, and the output shaft of the servo motor is fixedly connected to the second rotating roller adjacent to the servo motor.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting multiple groups of first transmission rollers, second transmission rollers, first gears, second gears and other components, the masterbatch can be driven to the cutting position through the rotation of the first transmission rollers and the second transmission rollers. At the same time, by stopping the rotation of the servo motor output shaft, the first transmission rollers and the second transmission rollers can limit the masterbatch, so that the masterbatch can be prevented from being displaced when cutting, thereby greatly improving the cutting accuracy of the masterbatch.

[0014] 2. By setting the first transmission wheel and the second transmission wheel, one of the second gears is driven to rotate by the servo motor, and the first transmission wheel is driven to rotate by the mutual engagement between the two second gears. The first transmission wheel drives the second transmission wheel to rotate through the transmission belt. In this way, the rotation of multiple groups of first transmission rollers and second transmission rollers can be achieved through one power source. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 , a masterbatch cutting device, including a box body 1, four first rotating rollers 2 and four second rotating rollers 4 are rotatably connected inside the box body 1, the four first rotating rollers 2 and the four second rotating rollers 4 are located in pairs on the same horizontal line, the outer wall of the box body 1 is rotatably connected to two first gears 5 and two second gears 6, the two first gears 5 are fixedly connected to the four first rotating rollers 2, and the two second gears 6 are fixedly connected to the four second rotating rollers 4, the two first gears 5 are meshed with each other, and the two second gears 6 are meshed with each other. A rotating mechanism for rotating the four first rotating rollers 2 and the four second rotating rollers 4 is installed on the outside of the box body 1. It should be noted that the provided feed port 3 can serve as a guide, and when the masterbatch is fed into the second rotating roller 4, it can be stably slid forward.

[0021] The rotating mechanism includes a first transmission wheel 9 and a second transmission wheel 10 which are rotatably connected to the outside of the box body 1. The first transmission wheel 9 and the second transmission wheel 10 are respectively fixedly connected to the first rotating roller 2 and the second rotating roller 4 adjacent to them. The first transmission wheel 9 is connected to the second transmission wheel 10 through a transmission belt 11. Two feed ports 3 are provided on the outer wall of the box body 1. The two feed ports 3 are communicated with the inside of the box body 1. An expansion plate 7 is fixedly connected to the outer wall of the box body 1. The upper end of the expansion plate 7 is fixedly connected to the bracket 8. The lower end of the bracket 8 is fixedly connected to the hydraulic cylinder 13. The telescopic end of the hydraulic cylinder 13 is fixedly connected to the blade 14. A discharge port 15 is provided on the outer wall of the box body 1. A servo motor 12 is fixedly connected to the outer wall of the box body 1. The output shaft of the servo motor 12 is fixedly connected to the second rotating roller 4 adjacent to it.

[0022] In the present invention, when using the device, the masterbatch is pushed into the second rotating roller 4 through the feed port 3. The functions of the four first rotating rollers 2 and the four second rotating rollers 4 are: driving the masterbatch to be transmitted to the discharge port 15 in pairs, and the functions of the two first gears 5 and the two second gears 6 are: meshing with each other in pairs, thereby driving the first rotating rollers 2 and the second rotating rollers 4 to rotate in pairs, thereby achieving the purpose of driving the masterbatch to be transmitted forward. The advantage of the first transmission wheel 9 and the second transmission wheel 10 is that the rotation of multiple groups of first rotating rollers 2 and second rotating rollers 4 can be achieved by a servo motor 12. When the masterbatch is transmitted to the expansion plate 7, the output shaft of the servo motor 12 stops rotating.
