Description

Technical Field

[0001] This utility model relates to the field of color masterbatch processing technology, and in particular to a color masterbatch melt extrusion equipment. Background Technology

[0002] Color masterbatch processing is a manufacturing process that mixes pigments or dyes with carrier resins, dispersants, and other additives through a specific process to produce high-concentration colored granules. During processing, each raw material is first accurately weighed according to the formula. Then, a twin-screw extruder is used to extrude the mixture in a high-temperature molten state, followed by cooling and pelletizing to finally obtain the color masterbatch product.

[0003] In masterbatch processing, as soon as the masterbatch strip is extruded from the extruder die, the worker must quickly put on heat-resistant gloves and grasp the end of the strip. Based on the extrusion speed, the strip is dragged evenly along a pre-set cooling water tank. During this dragging process, the strip smoothly enters the water tank for thorough cooling and shaping. The worker continues to drag the strip to the input end of the crushing device, preparing it for the subsequent pelletizing process.

[0004] The shortcomings of the existing technical solutions are as follows: Although the gloves provide some insulation, the freshly extruded masterbatch strips are extremely hot, and water cooling is required after output. The water on the gloves enhances heat conduction, allowing heat to be rapidly transferred and potentially scalding the workers' hands. Furthermore, inexperienced personnel may find it difficult to accurately control the matching between the dragging speed and the extrusion speed. Too high a speed will cause the masterbatch strips to become thinner or even break due to excessive stretching; too low a speed will cause the masterbatch strips to accumulate, reducing product quality. Utility Model Content

[0005] This invention provides a masterbatch melt extrusion device that can solve the problems of easy hand burns and difficulty in controlling the dragging speed in the prior art.

[0006] A masterbatch melt extrusion device includes a masterbatch melt extruder. The output end of the masterbatch melt extruder is provided with a cooling water tank for cooling masterbatch strips. A guide wheel bracket is provided on the cooling water tank. The device also includes a fixing mechanism for fixing the end of the masterbatch strips, a lifting mechanism for driving the fixing mechanism to rise and fall to adapt to the height of the guide wheel bracket, and a driving mechanism for driving the lifting mechanism and the fixing mechanism to move along the cooling water tank toward a masterbatch strip crushing device. The driving mechanism is fitted on the side of the cooling water tank, the lifting mechanism is fitted on the driving mechanism, and the fixing mechanism is fitted on the output end of the lifting mechanism.

[0007] As a further embodiment of this utility model: the fixing mechanism includes a support frame connected to the lifting mechanism, a hanger is fixedly installed at the lower end of the support frame, a fixed clamping plate is horizontally fixed on the hanger, a second electric telescopic rod is fixedly installed on the hanger, a U-shaped pull rod is fixedly installed at the output end of the second electric telescopic rod, and a movable clamping plate that cooperates with the fixed clamping plate is fixedly installed on the U-shaped pull rod.

[0008] As a further embodiment of this utility model, the adjacent surfaces of the fixed clamping plate and the movable clamping plate are provided with multiple sets of mutually cooperating grooves and protrusions.

[0009] As a further embodiment of this utility model: the lifting mechanism includes a slider that cooperates with the driving mechanism, a first electric telescopic rod is fixedly mounted on the slider, and the support frame is fixedly connected to the extension end of the first electric telescopic rod.

[0010] As a further embodiment of this utility model: an L-shaped hanging plate that slides with the upper edge of the cooling water tank is fixedly provided on one side of the first electric telescopic rod.

[0011] As a further embodiment of this utility model: the driving mechanism includes a guide rail fixedly mounted on the side of the cooling water tank, a conveyor belt assembly and a motor that drives the conveyor belt assembly to move, the slider being connected to the conveyor belt assembly and slidingly engaged with the guide rail.

[0015] As a further embodiment of this utility model, the U-shaped tie rod is slidably engaged with the hanger.

[0016] The beneficial effects of this utility model are:

[0017] 1. In use, the drive mechanism utilizes a motor to drive the conveyor belt assembly, precisely controlling the movement of the slider, which in turn drives the fixing mechanism to drag the color strip. This eliminates the need for manual labor, and the speed is stable and controllable. The first electric telescopic rod of the lifting mechanism automatically raises the fixing mechanism, allowing the color strip to smoothly pass over the guide wheel bracket. The entire process requires no manual intervention, greatly reducing manpower, lowering labor intensity, and avoiding the safety issue of burns.

[0018] 2. In use, the multiple sets of grooves and protrusions on the adjacent surfaces of the fixed and movable clamping plates of this invention can compress the ends of the color masterbatch strips into a three-dimensional U or L shape. This shape increases the structural strength of the ends of the color masterbatch strips, enabling them to withstand strong tensile forces after solidification, effectively avoiding breakage during dragging and ensuring production stability. Simultaneously, the second electric telescopic rod can flexibly control the movement of the movable clamping plate, enabling rapid clamping and loosening of the color masterbatch strips, making operation convenient and efficient.

[0024] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0025] like Figures 1 to 3 As shown in the figure, the present invention provides a masterbatch melt extrusion device, including a masterbatch melt extruder 1. A cooling water tank 2 for cooling the masterbatch strips is provided at the output end of the masterbatch melt extruder 1. A guide wheel bracket 6 is provided on the cooling water tank 2. Figure 2As shown. The device also includes a fixing mechanism 4 for fixing the end of the masterbatch strip, a lifting mechanism 3 for driving the fixing mechanism 4 to rise and fall to match the height of the guide wheel bracket 6, and a drive mechanism 5 for driving the lifting mechanism 3 and the fixing mechanism 4 to move along the cooling water tank 2 toward the masterbatch strip crushing device. The drive mechanism 5 is fitted on the side of the cooling water tank 2, the lifting mechanism 3 is fitted on the drive mechanism 5, and the fixing mechanism 4 is fitted on the output end of the lifting mechanism 3. In use, the fixing mechanism 4 fixes the end of the masterbatch strip, and the drive mechanism 5 drives the lifting mechanism 3 and the fixing mechanism 4 to move the masterbatch strip output from the masterbatch granule melt extruder 1 along the cooling water tank 2 toward the crushing device. The masterbatch strip gradually cools and solidifies in the cooling water tank 2. When it reaches the position of the guide wheel bracket 6, the lifting mechanism 3 lifts the end of the masterbatch strip. Since the masterbatch strip at this position has cooled and solidified, the lifting mechanism 3 allows the masterbatch strip to rest on the guide wheel bracket 6 and move, thus making it easier to enter the crushing device.

[0026] In one specific embodiment, the fixing mechanism 4 includes a support frame 401 connected to the lifting mechanism 3. A hanger 402 is fixedly mounted on the lower end of the support frame 401. A fixed clamping plate 405 is horizontally fixed to the hanger 402. A second electric telescopic rod 403 is fixedly mounted on the hanger 402. A U-shaped pull rod 404 is fixedly mounted at the output end of the second electric telescopic rod 403. A movable clamping plate 406, which cooperates with the fixed clamping plate 405, is fixedly mounted on the U-shaped pull rod 404. The U-shaped pull rod 404 and the hanger 402 are slidably engaged. Figure 3 As shown. When the masterbatch melt extruder 1 outputs masterbatch strips, the masterbatch strips will fall into the cooling water tank 2 under the action of gravity, and fall between the fixed clamping plate 405 and the movable clamping plate 406. The second electric telescopic rod 403 extends, driving the movable clamping plate 406 to move closer to the fixed clamping plate 405, so that the end of the masterbatch strip is clamped between the fixed clamping plate 405 and the movable clamping plate 406, thus completing the fixation of the end of the masterbatch strip.

[0027] Since the newly produced color masterbatch is relatively soft, the end of the color masterbatch will be squeezed by the plane after clamping, which can easily cause it to break during dragging. Multiple sets of mutually cooperating grooves and protrusions can be provided on the close surfaces of the fixed clamping plate 405 and the movable clamping plate 406, so that the end of the color masterbatch will be squeezed into a three-dimensional U-shape or L-shape, thereby improving the tensile force that the color masterbatch can withstand after condensation.

[0028] In one specific embodiment, the lifting mechanism 3 includes a slider 304 that cooperates with the drive mechanism 5. A first electric telescopic rod 301 is fixedly mounted on the slider 304, and a support frame 401 is fixedly connected to the extension end of the first electric telescopic rod 301. The first electric telescopic rod 301 can raise the fixing mechanism 4, thereby driving the end of the color masterbatch strip past the guide wheel bracket 6 and closer to the input end of the crushing and rotating device.

[0029] An L-shaped hanging plate 302 is fixedly installed on one side of the first electric telescopic rod 301, which slides and engages with the upper edge of the cooling water tank 2. A roller 303 is rotatably installed on the inner side of the L-shaped hanging plate 302, which engages with the edge of the cooling water tank 2, to maintain the relative position of the first electric telescopic rod 301 and the cooling water tank 2 and ensure stability during movement.

[0030] The drive mechanism 5 includes a guide rail 501 fixedly mounted on the side of the cooling water tank 2. A groove extending along the guide rail 501 is formed on the guide rail 501. A conveyor belt assembly 503 is fitted inside the groove. The conveyor belt assembly 503 includes two sets of rotating wheels rotatably mounted at both ends inside the groove, and a conveyor belt fitted on the rotating wheels. A slider 304 has a protrusion fixedly connected to the conveyor belt and slidingly engaged with the groove. A motor 502 is fitted on the guide rail 501 to drive the rotating wheels. The motor 502 drives the conveyor belt assembly 503, which in turn moves the slider 304 and its fixing mechanism 4, thereby dragging the end of the color masterbatch strip.

[0031] A bottom wheel 305 is rotatably mounted on the slider 304 to cooperate with the guide rail 501, thereby reducing the friction between the slider 304 and the guide rail 501.

[0032] Working principle: After the masterbatch melt extruder 1 outputs masterbatch strips, the strips fall into the cooling water tank 2 under gravity. At this time, the second electric telescopic rod 403 extends, driving the movable clamping plate 406 to move closer to the fixed clamping plate 405, clamping the end of the masterbatch strip that has fallen between them. The adjacent surfaces of the fixed clamping plate 405 and the movable clamping plate 406 are provided with multiple sets of grooves and protrusions, so that the end of the masterbatch strip is squeezed into a three-dimensional U-shape or L-shape, enhancing the tensile strength of the masterbatch strip after condensation.

[0033] After the ends of the color masterbatch are fixed, the motor 502 drives the conveyor belt assembly 503 to operate. The conveyor belt is connected to the slider 304, thereby driving the slider 304 and the lifting mechanism 3 and fixing mechanism 4 fixed on the slider 304 to move together along the cooling water tank 2. During this process, the color masterbatch gradually cools and solidifies in the cooling water tank 2, realizing the transformation from a soft state to having a certain hardness and strength, preparing it for smooth entry into the crushing device.

[0034] When the strip moves to the guide wheel bracket 6, the first electric telescopic rod 301 extends, raising the fixing mechanism 4, which in turn lifts the end of the color masterbatch. Since the color masterbatch has cooled and solidified at this point, it possesses sufficient strength to smoothly rest on the guide wheel bracket 6. The guide wheel bracket 6 provides support and guidance for the movement of the color masterbatch, allowing it to move more smoothly towards the crushing device and preventing sagging or swaying from affecting its smooth entry into the crushing device.

[0035] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
