Description

Technical Field

[0001] This invention belongs to the field of granulation equipment technology, specifically relating to a method and apparatus for preparing white weather-resistant toughening masterbatch. Background Technology

[0002] Color masterbatch is a new type of special colorant for polymer materials, also known as pigment preparation. Color masterbatch is mainly used in plastics. It consists of three basic elements: pigment or dye, carrier, and additives. The preparation of color masterbatch involves mixing and heating the raw materials in an extruder, and then extruding them into granules.

[0003] Existing extrusion granulation equipment operates at relatively high temperatures during extrusion. Even with a cooling system, masterbatch adhesion inevitably occurs, affecting the quality of the final product. Summary of the Invention

[0004] The purpose of this invention is to provide a color masterbatch preparation apparatus with a simple structure that can separate adhered color masterbatches in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] On one hand, a device for preparing white weather-resistant toughened masterbatch is proposed, including an extruder and a separation mechanism installed below the extruder outlet. The separation mechanism includes a tiltable box, inside which at least two tamping plates are installed. The tamping plates are slidably connected to the bottom of the box. The tamping plates can move linearly under the drive of a first driving device. The distance between two adjacent tamping plates is greater than the diameter of a single masterbatch but less than the sum of the diameters of two masterbatches. The ends of the tamping plates separate connected masterbatches with a total diameter greater than the distance between two adjacent tamping plates. A kneading plate is provided in the middle of the tamping plate. Movable blocks are connected to both ends of the kneading plate. A movable groove is provided on the top of the box. A sliding groove is provided on the inner wall of the movable groove. The sliding groove is a smooth channel with one end higher than the other. The movable blocks are movably connected to the sliding groove. The kneading plate moves left and right under the drive of the second driving device, so that the bottom of the kneading plate contacts the top of the masterbatch, allowing the masterbatch to roll on the inner bottom of the box.

[0007] As a further optimization of the present invention, the distance between two adjacent tamping plates is greater than the diameter of a single color masterbatch and less than 1.5 times the diameter of a color masterbatch.

[0008] As a further optimization of the present invention, a limiting block is provided between the end of the tamping plate and the kneading plate. The limiting block is inserted between two adjacent tamping plates. The distance between the lowest point of the limiting block and the inner bottom of the box is greater than the diameter of a single color masterbatch and less than the sum of the diameters of two color masterbatches.

[0009] As a further optimization of the present invention, the limiting block is triangular, and the tip of the triangular limiting block faces the end of the tamping plate.

[0010] As a further optimization of the present invention, a kneading block is connected to the bottom of the kneading board, and the kneading block extends into the gap between two adjacent pounding boards.

[0011] As a further optimization of the present invention, the end of the tamping plate is provided with a protrusion, and the end of the tamping plate near the front and rear side walls of the box is provided with an inclined block.

[0012] As a further optimization of the present invention, the end of the tamping plate is provided with a material discharge component, the material discharge component includes a rotatable baffle plate, the bottom of the baffle plate is provided with a slidable top rod, the top rod is slidably connected to the bottom of the box body, an elastic component is installed between the top rod and the box body, and a linear drive device is provided at the bottom of the top rod, the linear drive device drives the top rod to move up and down.

[0013] As a further optimization of the present invention, a driving mechanism is also included. The driving mechanism includes a driving rod that rotates under the drive of a rotary driving device. A first cam is rotatably connected to the outer wall of the housing. The first cam drives a movable block to move. One end of the driving rod and one end of the first cam are both connected to a sprocket. The two sprockets are connected by a chain drive. The other end of the driving rod is connected to a first gear. A second gear is provided below the first gear, and the two mesh with each other. A residual gear is connected to the middle of the second gear. A base is provided at the bottom of the housing. A rack is slidably connected to the base. The residual gear meshes with the rack. One end of the rack is elastically connected to the base through an elastic element. The other end of the rack is connected to a wedge block. The inclined surface of the wedge block contacts the bottom of the top rod.

[0014] On the other hand, the present invention also proposes a method for preparing white weather-resistant toughening masterbatch, comprising the following steps:

[0015] 1. At least two tamping plates move in a staggered manner under the drive of external force. After the masterbatch is discharged from the outlet, it rolls to one end of the tamping plate. The ends of the two adjacent tamping plates tamp the masterbatch that is stuck together, so that the masterbatch can pass through the channel formed between the two adjacent tamping plates.

[0016] Second: The kneading plate set in the middle of the mixing plate moves under the drive of the driving device, causing the masterbatch to roll on the inner bottom of the box.

[0017] The beneficial effects of the present invention are as follows: The present invention sets up multiple staggerable and movable mixing plates to break up the color masterbatch into strips and enter them into the gaps between the mixing plates. Then, the color masterbatch is made to roll by the kneading plate. Multiple color masterbatches rotate at the same time, thereby separating the color masterbatches that are stuck together.

Detailed Implementation

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example

[0027] like Figure 1-6As shown, a preparation device for white weather-resistant toughened masterbatch includes a separation mechanism 100 installed below the discharge port of an extruder. The separation mechanism 100 includes a tiltable box 110. Due to the tilt, the masterbatch can roll off. At least two tamping plates 120 are installed inside the box 110. The tamping plates 120 are slidably connected to the bottom of the box 110. The tamping plates 120 can move linearly under the drive of a first driving device.

[0028] It should be noted that the aforementioned first driving device can be an electric telescopic rod, an electric ball screw, or other devices with linear driving function;

[0029] The distance between two adjacent tamping plates 120 is greater than the diameter of a single masterbatch but less than the sum of the diameters of the two masterbatches. The ends of the tamping plates 120 separate connected masterbatches whose total diameter is greater than the distance between two adjacent tamping plates 120 (e.g., Figure 3 As shown, state a can be changed to state b under the action of the tamping plate 120;

[0030] A kneading plate 140 is provided in the middle of the mixing plate 120. Movable blocks 142 are connected to both ends of the kneading plate 140. A movable groove 143 is provided on the top of the housing 110. A sliding groove 144 is provided on the inner wall of the movable groove 143. The sliding groove 144 is a smooth channel with one end higher than the other. The movable blocks 142 are movably connected to the sliding groove 144. Driven by the second drive device, the kneading plate 140 moves left and right, causing its bottom to contact the top of the masterbatch, allowing the masterbatch to roll on the inner bottom of the housing 110. When the kneading plate 140 moves to the right side of the sliding groove 144, it is at its lowest point. Continuing to move to the right allows the bottom of the kneading plate 140 to contact the masterbatch 400, causing the masterbatch 400 to rotate (e.g., ...). Figure 2 (as shown in part c);

[0031] The aforementioned second driving device can be a device with linear driving effect, such as an electric telescopic rod or an electric lead screw.

[0032] The distance between two adjacent tamping plates 120 is greater than the diameter of a single masterbatch but less than 1.5 times the diameter of a masterbatch. Therefore, the gap between the tamping plates 120 can only allow the masterbatch to enter in a straight line.

[0033] See Figure 4 A limiting block 130 can also be provided between the end of the tamping plate 120 and the kneading plate 140. The limiting block 130 is inserted between two adjacent tamping plates 120. The distance between the lowest point of the limiting block 130 and the inner bottom of the box 110 is greater than the diameter of a single color masterbatch and less than the sum of the diameters of two color masterbatches.

[0034] Further optimization of the limiting block 130 is to make it triangular, with the tip of the triangular limiting block 130 facing the end of the mixing plate 120. The limiting block 130 prevents the color masterbatch 400 from stacking up and down and entering below the kneading plate 140, thereby effectively separating the adhered color masterbatch 400.

[0035] See Figure 5 The bottom of the kneading board 140 is connected to a kneading block 141, which can extend into the gap between two adjacent ramming boards 120.

[0036] The end of the tamping plate 120 is provided with a protrusion 121, and the end of the tamping plate 120 near the front and rear side walls of the box body 110 is provided with an inclined block 122. The protrusion 120 can be used to initially separate the adhered color masterbatch 400.

[0037] The end of the tamping plate 120 is provided with a material discharge component 200, which includes a rotatable baffle plate 210. The bottom of the baffle plate 210 is provided with a slidable top rod 220. The top rod 220 is slidably connected to the bottom of the box 110. An elastic component 230 is installed between the top rod 220 and the box 110. The bottom of the top rod 220 is provided with a linear drive device. The linear drive device can be an electric push rod, a lead screw, or any device with a linear drive effect. The linear drive device drives the top rod 220 up and down.

[0038] It also includes a drive mechanism 300, which includes a drive rod 310. The drive rod 310 rotates under the drive of a rotary drive device, which can be a motor.

[0039] See Figure 6The outer wall of the housing 110 is rotatably connected to a first cam 150, which drives the movable block 142 to move. One end of the drive rod 310 and one end of the first cam 150 are both connected to sprockets 370, which are connected by a chain 380. The other end of the drive rod 310 is connected to a first gear 320, and a second gear 330 is located below the first gear 320. The two gears mesh with each other. A residual gear 340 is connected to the middle of the second gear 330. A base is located at the bottom of the housing 110, and a rack 350 is slidably connected to the base. The residual gear 340 meshes with the rack 350. One end of the rack 350 is elastically connected to the base via an elastic element 360. The component 360 can be a spring or an elastic sheet. The other end of the rack 350 is connected to a wedge block 240. The inclined surface of the wedge block 240 contacts the bottom of the push rod 220. When the residual gear 340 rotates, it drives the rack 350 to move linearly. Then the wedge block 240 at one end of the rack 350 moves. Then the wedge block 240 drives the push rod 220 to move upward, so that the baffle plate 210 is lifted and the color masterbatch 400 cannot roll to the right. Then, when the broken part of the residual gear 340 is at the bottom, it disengages from the rack 350. Then, under the action of the elastic component 360, the rack 350 returns to its position. At this time, the wedge block 240 is located on the left and right sides, and the push rod 220 falls down, so that the baffle plate 210 is lowered and the color masterbatch 400 rolls down normally.

[0040] like Figure 2 As shown, it should be noted that a second cam 390 is installed in the middle of the drive rod 310. There are multiple second cams 390. The multiple second cams 390 contact the right end of each tamping plate 120. The right end of the tamping plate 120 is elastically connected to the inner wall of the box 110 through a compression spring. The compression spring is in a contracted state by default. When the convex part of the cam 390 rotates to one end of the tamping plate 120, it causes the tamping plate 120 to move to the left. Each second cam 390 can be misaligned, so that multiple tamping plates 120 can also move in a misaligned manner, so that the adhered masterbatch 400 can be more easily tamped and rolled into the gap of the tamping plate 120.

[0041] This invention also proposes a method for preparing white weather-resistant toughening masterbatch, comprising the following steps:

[0042] 1. At least two tamping plates move in a staggered manner under the drive of external force. After the masterbatch is discharged from the outlet, it rolls to one end of the tamping plate. The ends of the two adjacent tamping plates tamp the masterbatch that is stuck together, so that the masterbatch can pass through the channel formed between the two adjacent tamping plates.

[0043] Second: The kneading plate set in the middle of the mixing plate moves under the drive of the driving device, causing the masterbatch to roll on the bottom of the box, thereby separating the masterbatch that is stuck together. Finally, the separated masterbatch is discharged from the discharge port on the box 110.

[0044] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
