Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch manufacturing, in particular to a pre-drying treatment device for cutting masterbatch plastic strips into pellets. Background Art

[0002] Masterbatch is a plastic colorant formed by well-dispersing a high proportion of pigments or additives and thermoplastic resins. The selected resin has good wetting and dispersing effects on the colorant and good compatibility with the material to be colored.

[0003] At present, the domestic production process of masterbatch is to mix a carrier with color powder or filler by high-speed stirring and then put them into an extruder to extrude and granulate. The extruder is used to knead and plasticize the granulation raw materials to form a plastic melt, and the plastic melt is extruded into a plastic strip by the die head of the extruder. After the plastic strip is cooled and dried, the plastic strip is cut into plastic particles of a certain length by a plastic strip granulator. Since the water cooling effect is good, the plastic strip is usually cooled by the water cooling method. After water cooling, it is pre-dried and then chopped by the granulator. However, the pre-drying usually directly uses a blower to dry, and the drying efficiency is not high and the effect is poor, which affects the granulation quality and efficiency of the next process. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present utility model.

[0023] Embodiment 1

[0024] As shown in the attached Figure 1 and the attached Figure 2 As shown, a pre-drying treatment device for cutting color masterbatch plastic strips includes a drying box 1. A support frame 2 is installed at the bottom of the drying box 1. A cover plate 3 is installed at the rear of the drying box 1. Two groups of feed ports 4 are provided on the front side wall of the drying box 1. Two groups of discharge ports 5 are provided on the cover plate 3. Multiple groups of motors 9 are installed on the outer wall of the cover plate 3. The shaft end of the motor 9 rotates through the interior of the drying box 1 and is connected with a duct 10. Multiple exhaust holes 14 are provided on the side wall of the duct 10. A spiral fin 11 is sleeved outside the duct 10. The other end of the duct 10 is rotatably installed with a supply duct 12 through a rotary joint. The other end of the supply duct 12 slides out of the drying box 1 and is installed with a connecting sleeve 13.

[0025] Through the above structure, the cooled color masterbatch plastic strips are sent into the interior of the drying box 1 through the feed ports 4. The color masterbatch plastic strips are in contact with the spiral fins 11. The spiral fins 11 are made of rubber. The rotation direction of the spiral fins 11 is adjusted to the feeding state. The two spiral fins 11 can drive the color masterbatch plastic strips to move, and convey the color masterbatch plastic strips towards the discharge port 5. When the connecting sleeve 13 is connected to an external air supply device, air is sent into the interior of the duct 10 through the connecting sleeve 13, and the air is sent towards the color masterbatch plastic strips through the multiple exhaust holes 14 on the duct 10 to dry the color masterbatch plastic strips.

[0026] Combined with the attached Figure 4 and the attached Figure 5 For the number of spiral fins 11 for conveying the color masterbatch plastic strips, three groups or four groups can be selected. Three groups of spiral fins 11 can control the rotation direction. When one group of feed ports 4 is being maintained, the other group of feed ports 4 can feed normally. When four groups of spiral fins 11 are operating, the two groups of feed ports 4 can achieve simultaneous feeding to improve the drying efficiency. The specific structure is as follows:

[0027] Combined with the attached Figure 2 and the attached Figure 3 As shown, the axes of the feed ports 4 and the discharge ports 5 correspond to each other. The duct 10 is located diagonally below the discharge port 5. A guide hole 15 for the supply duct 12 to pass through is provided on the front side wall of the drying box 1.

[0028] Through the above structure, the masterbatch plastic strip passes through the inside of the feed inlet 4 and the discharge outlet 5. Since the masterbatch plastic strip is prone to bending, the air duct 10 is located diagonally below the discharge outlet 5, so that the spiral fins 11 can support and limit the masterbatch plastic strip. When the air duct 10 rotates, since the air supply duct 12 is connected to the air duct 10 through a rotary joint, the air supply duct 12 will not rotate with the air duct 10, and the air supply duct 12 passes through the drying oven 1 through the guide hole 15.

[0029] Combined with the attached Figure 1 and the attached Figure 3 As shown, a plurality of drainage holes 16 are provided at the bottom of the drying oven 1, and a controller 17 is installed on the upper side of the drying oven 1. The controller 17 is connected to a plurality of motors 9.

[0030] Through the above structure, the water on the masterbatch plastic strip is discharged from the drying oven 1 through a plurality of drainage holes 16, and the start / stop and rotation direction of a plurality of motors 9 can be controlled through the controller 17.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, please refer to the attached Figure 1 and the attached Figure 4 , a threaded mounting tube 6 is installed on the front side of the drying oven 1 and outside the feed inlet 4. A threaded sleeve 7 is installed outside the threaded mounting tube 6, and a water-absorbing sponge 8 is installed inside the threaded sleeve 7.

[0033] Through the above structure of Embodiment 2, the threaded sleeve 7 is installed outside the threaded mounting tube 6. When the masterbatch plastic strip passes through the feed inlet 4, the water on the surface of the masterbatch plastic strip is adsorbed by the water-absorbing sponge 8. When the three spiral fins 11 mentioned in Embodiment 1 act, by adjusting the rotation direction of the spiral fins 11, when replacing the water-absorbing sponge 8, the other feed inlet 4 can feed materials normally.
