Technical Field

[0001] The utility model relates to the technical field of masterbatch molding extruders, in particular to a material receiving device for a masterbatch molding extruder. Background Art

[0002] In the prior art, when EPP is granulated by extrusion, the process is to put high melt strength PP particles and compounding agents into the extruder to melt, then extrude them from the die hole to reduce pressure and foam, and cut them into small beads by a cutting mechanism before discharging and collecting. Since the material coming out of the extruder usually contains a lot of water, it is not conducive to storage and subsequent secondary foaming. In addition, the material often contains fine impurities, so the material needs to be dried and vibrated (to remove fine impurities) before being bagged for use or secondary foaming.

[0003] The material receiving device at the discharge end of the existing masterbatch molding extruder, such as the announcement number CN207105343U, is named as an automatic fine screening and collecting device for the discharge of an EPP granulation extruder, which is characterized in that it includes a bracket and a vibrating screen box arranged on the bracket by a shock absorber, the bottom of the vibrating screen box is provided with an opening and connected to the screening hopper, the opening is provided with a screen to separate the vibrating screen box from the screening hopper, and a vibrator is fixed to the bottom of the vibrating screen box or the screening hopper; an extension frame is also fixed to the bracket, and a drop hopper located above the vibrating screen box is fixed on the extension frame, the upper part of the vibrating screen box is provided with a feed port opposite to the drop port at the bottom of the drop hopper, and a discharge port is provided on the side of the vibrating screen box; it also includes a feeding hopper arranged on one side of the bracket and a fan connected to the air inlet on the feeding hopper through an air supply pipe, and the feeding hopper is connected to the feed port on the upper part of the drop hopper through a conveying pipeline.

[0004] During the use of the above device, it is necessary to go through multiple steps such as drying, cooling, primary screening, fine screening, etc. in sequence to complete the material processing of the masterbatch, and the efficiency is low; therefore, we propose a material receiving device for a masterbatch molding extruder to solve the above problems.

[0006] To achieve the above object, the utility model provides the following technical solution: a material receiving device for a masterbatch molding extruder, comprising a vibrating screen, wherein a feed port is installed above one end of the vibrating screen;

[0007] Also includes:

[0008] Support legs, which are arranged on both sides of the vibrating screen, and four support legs are arranged;

[0009] A vibration table, which is installed on the lower surface of the vibration screen, and a vibration motor is installed at the rear end of the vibration table;

[0010] A fine screen is installed inside the vibrating screen, a first baffle is installed at one end of the fine screen, a coarse screen is arranged above the fine screen, a second baffle is installed at one end of the coarse screen, a first discharge port is arranged below the inner side of the first baffle, a second discharge port is arranged below between the first baffle and the second baffle, and a third discharge port is arranged below the outer side of the second baffle;

[0016] Preferably, a bracket is installed at the rear end of the cooling box.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The utility model installs a cooling box at the feed port of the vibrating screen, and sets two layers of screens, a coarse screen and a fine screen, in the vibrating screen. Since the temperature of the masterbatch is too high after drying, it will cause adhesion in the subsequent screening process. Therefore, the cooling box and the masterbatch are efficiently cooled in the air delivery stage, and the primary screening and fine screening of the masterbatch are completed at one time with the double-layer screening structure. Compared with conventional devices, the efficiency is significantly improved, and the problem of low efficiency in the existing device, which requires drying, cooling, primary screening, fine screening and other steps in sequence to complete the material processing of the masterbatch, is solved.

[0019] 2. The vibrating screen and the cooling box are connected by non-woven gauze segments. Since the non-woven gauze segments are made of flexible materials, the vibration of the vibrating screen will not affect the cooling box. At the same time, the non-woven gauze segments are breathable and dust-proof, which can not only ensure the natural discharge of the air-conveying gas, but also make the entire processing process in a dust-free environment, avoiding the influence of dust on the quality of the masterbatch.

[0032] The non-woven gauze segment 11 is installed above the feed port 10 , and a docking port 12 is installed at the upper end of the non-woven gauze segment 11 , a cooling box 13 is installed at the upper end of the docking port 12 , and an air delivery pipe joint 16 is installed at the upper end of the cooling box 13 .

[0033] See also Figure 2 and Figure 3 A flexible sheath 6 is installed at the upper end of the supporting leg 5, a connecting plate 7 is installed at the upper end of the flexible sheath 6, and the connecting plate 7 is welded to the vibrating screen 1. A spring 18 is installed inside the flexible sheath 6, and a guide rod 19 is installed inside the spring 18. The flexible sheath 6 has a good dust-proof protection effect on the spring 18 component and extends the service life of the spring 18. The spring 18 can cooperate with the vibration motor 21 to drive the vibrating screen 1 to vibrate and achieve screening. The guide rod 19 can control the amplitude of the spring 18 to avoid excessive deformation.

[0034] See also Figure 1 The upper end of the connecting plate 7 is welded to the vibrating screen 1 through a reinforcing plate 8. The reinforcing plate 8 is a triangular structure, which ensures the structural strength of the connecting plate 7.

[0035] See also Figure 1 A reinforcement rod 9 is installed between the support legs 5, and the reinforcement rod 9 is welded to the support legs 5, and the reinforcement rod 9 ensures the stability of the support of the support legs 5.

[0036] See also Figure 5 A serpentine bending tube 26 is installed inside the cooling box 13, and both ends of the serpentine bending tube 26 are connected with the air delivery pipe joint 16 and the docking port 12. A water inlet 14 is arranged above the front end of the cooling box 13, and a water return port 15 is arranged below the front end of the cooling box 13.

[0038] Working principle: When in use, the fan delivers the dried masterbatch into the cooling box 13 through the air delivery pipeline. The cooling box 13 is connected to an external circulating water cooling device, so that when the masterbatch moves along the serpentine bending tube 26, the external cooling water can quickly exchange heat to achieve the purpose of cooling the masterbatch, and avoid the situation where the temperature of the masterbatch is too high after drying, which leads to adhesion in the subsequent screening process. The cooled masterbatch enters the vibrating screen 1 along the non-woven gauze segment 11, and gradually moves toward the lower feed port along the coarse screen 24 under the action of the vibration motor 21. During the movement, large-particle masterbatch will remain on the surface of the coarse screen 24, and the remaining masterbatch will fall to the fine screen 22, which will perform secondary screening. Fine materials smaller than the specifications of conventional masterbatch may further fall below the fine screen 22, thereby realizing secondary screening. The three types of materials that have been screened are discharged from the first feed port 2, the second feed port 3 and the third feed port 4 respectively, and can be conveniently collected by bagging at the feed port.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
