Description

Technical Field

[0001] This utility model belongs to the field of masterbatch production technology, specifically relating to a molding device for polyester masterbatch. Background Technology

[0002] With the continuous increase in domestic polyester production capacity, the oversupply situation in the polyester market will persist for a long time. Conventional products have poor profitability. As polyester product prices decline, their application areas are gradually expanding. Therefore, developing functional polyester products can increase product added value and enhance profitability. This process requires first mixing powdered functional materials into polyester granules using a mixer, then manually adding the mixed polyester compound to a twin-screw extruder for granulation, followed by cooling and molding. However, during cooling, only the cooling water temperature in the localized area in contact with the masterbatch strip gradually rises, while the temperature in other areas remains constant. This prevents rapid circulation of the cooling water, reducing cooling efficiency. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a molding device for polyester masterbatch.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A molding apparatus for polyester masterbatch includes a first frame, a first extruder at the left end of the first frame, a first extrusion die at the right end of the first extruder, a first cooling mechanism at the right end of the first frame, the first cooling mechanism including a first cooling tank and a first lifting tank, a first mounting slot at the right end of the first frame, the first cooling tank being disposed within the first mounting slot, the first lifting tank being disposed within the first cooling tank, first clearance openings on both sides of the first lifting tank, a first support frame at the right end of the first frame, a first driving mechanism at the upper end of the first support frame, and the first driving mechanism being connected to the first lifting tank.

[0005] Furthermore, the first driving mechanism includes a first driving motor, a first rope, a first take-up reel, and a first rotating wheel. The first rotating wheel is disposed at both ends of the first support frame, and the first take-up reel is disposed on one side of the first rotating wheel. The first driving motor is drivenly connected to the first take-up reel. One end of the first rope is connected to the first take-up reel, and the other end of the first rope passes around the first rotating wheel and is connected to the first lifting groove.

[0006] Furthermore, a second rotating wheel is provided at both ends of the first cooling tank, the second rotating wheel corresponding to the opening of the first cooling tank, and a third rotating wheel is provided below the second rotating wheel, the third rotating wheel matching the first clearance opening.

[0007] Furthermore, a first circulation mechanism is provided at the lower end of the first cooling tank. The first circulation mechanism includes a second drive motor and a first impeller. The first impeller is disposed at the bottom of the first cooling tank, and the second drive motor is disposed at the lower end of the first frame. The second drive motor is connected to the first impeller.

[0008] Furthermore, the bottom of the first cooling tank is provided with a plurality of first pads, and the two ends of the first cooling tank are provided with a plurality of first stops, the first stops matching the first clearance opening.

[0009] The present invention discloses a molding device for polyester masterbatch. Compared with the prior art, its advantages are that it has a simple structure, is stable and reliable, and can repeatedly raise and lower the first lifting groove. Through the raising and lowering of the first lifting groove, the local cooling water is driven to flow, promoting heat exchange between the cooling waters. This avoids the local cooling water temperature in contact with the masterbatch strip being significantly higher than that in other areas, resulting in poor cooling effect and improving cooling molding efficiency.

[0017] Preferred embodiment.

[0018] This embodiment provides a molding apparatus for polyester masterbatch, including a first frame 100. A first extruder 120 is provided at the left end of the first frame 100, and a first extrusion die 130 is provided at the right end of the first extruder 120. A first cooling mechanism is provided at the right end of the first frame 100. The first cooling mechanism includes a first cooling groove 320 and a first lifting groove 300. A first mounting groove 110 is provided at the right end of the first frame 100. The first cooling groove 320 is disposed in the first mounting groove 110, and the first lifting groove 300 is disposed in the first cooling groove 320. First clearance openings 310 are provided on both sides of the first lifting groove 300. A first support frame 140 is provided at the right end of the first frame 100. A first driving mechanism is provided at the upper end of the first support frame 140, and the first driving mechanism is connected to the first lifting groove 300.

[0019] Furthermore, the first driving mechanism includes a first driving motor 200, a first rope 230, a first take-up reel 210, and a first rotating wheel 220. The first rotating wheel 220 is disposed at both ends of the first support frame 140, and the first take-up reel 210 is disposed on one side of the first rotating wheel 220. The first driving motor 200 is drivingly connected to the first take-up reel 210. One end of the first rope 230 is connected to the first take-up reel 210, and the other end of the first rope 230 passes around the first rotating wheel 220 and is connected to the first lifting groove 300.

[0020] Furthermore, the first cooling groove 320 is provided with second rotating wheels 330 at both ends, the second rotating wheels 330 corresponding to the groove opening of the first cooling groove 320, and a third rotating wheel 340 is provided below the second rotating wheel 330, the third rotating wheel 340 matching the first clearance opening 310.

[0021] Furthermore, a first circulation mechanism is provided at the lower end of the first cooling tank 320. The first circulation mechanism includes a second drive motor 400 and a first impeller 410. The first impeller 410 is disposed at the bottom of the first cooling tank 320, and the second drive motor 400 is disposed at the lower end of the first frame 100. The second drive motor 400 is connected to the first impeller 410.

[0022] Furthermore, the bottom of the first cooling tank 320 is provided with a plurality of first pads 420, and the two ends of the first cooling tank 320 are provided with a plurality of first blocks 430, the first blocks 430 being matched with the first clearance opening 310.

[0023] Working principle: After the first extruder 120 extrudes the masterbatch strip through the first extrusion die 130, it enters the first cooling tank 320 through the second roller 330, and then passes horizontally through the first cooling tank 320 through the third roller 340. It then passes through the first lifting groove 300 through the first clearance port 310, and exits the first cooling tank 320 through the third roller 340 and the second roller 330. The first drive motor 200 repeatedly reverses forward and backward, driving the first take-up roller 210 to reverse, thereby realizing the take-up and unwinding of the first rope 230. This drives the first lifting groove 300 to move up and down. During the upward movement of the first lifting groove 300, it pushes the locally heated cooling water upward and discharges it to both sides through the first clearance port 310, pushing the cooling water from the bottom to the masterbatch strip, thus preventing localized heating from affecting the cooling efficiency of the masterbatch strip. Simultaneously, the second drive motor 400 drives the first impeller 410 to rotate, rapidly mixing the hot water that comes out with the cold water between the first cooling tank 320 and the first lifting tank 300, accelerating the circulation of hot and cold water, and also helping to dissipate heat and improve the cooling effect of the cooling water on the masterbatch strip. During the lifting process, the first pad block 420 can limit the descent of the first lifting tank 300 and prevent the first lifting tank 300 from pressing against the first impeller 410, thus preventing wear on the first impeller 410. The first stop block 430 restricts the rise of the first lifting tank 300 within the first clearance opening 310, preventing the first lifting tank 300 from moving out and also preventing the first lifting tank 300 from hitting the masterbatch strip, ensuring the continuity of the masterbatch strip.
