[0029] For the purpose of making the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] Embodiment 1

[0031] As shown in Figure 1 and Figure 2 and Figure 3As shown, a masterbatch dispensing device for cable sheaths is used in conjunction with a tank body 11. A stirring mechanism is arranged inside the tank body 11. The stirring mechanism has a stirring shaft 12. The dispensing device includes a material box 21 and an extrusion disc 25 sleeved on the stirring shaft 12. A notch 251 is arranged on the extrusion disc 25;

[0032] A plurality of the material boxes 21 are provided. The plurality of material boxes 21 are circumferentially distributed around the stirring shaft 12. In this embodiment, two are taken as an example. The number of material boxes 21 used can be determined according to the types of materials required for the product. The product in this embodiment is a masterbatch for cable sheaths. The lower end of the material box 21 is connected through a material pipe 22. The material outlet at the lower end of the material pipe 22 penetrates the side wall of the tank body 11 and extends into the interior of the tank body 11. A notch 221 is arranged on the side wall of the material pipe 22 close to the extrusion disc 25. A material blocking member 23 is arranged in the material pipe 22. The material blocking member 23 movably penetrates the notch 221. A reset member 24 is arranged between the material blocking member 23 and the material pipe 22;

[0033] When stirring and mixing the materials inside the tank body 11, the stirring mechanism is started to drive the stirring shaft 12 to rotate. The stirring shaft 12 drives the extrusion disc 25 to rotate synchronously. The material blocking member 23 abuts against the extrusion disc 25 to close the material outlet. The material blocking member 23 is opposite to the notch 251. The reset member 24 drives the material blocking member 23 to extend out of the notch 221 to open the material outlet. A plurality of material outlets are opened in sequence to feed materials into the tank body 11 in batches.

[0034] A dispensing method for a masterbatch dispensing device for cable sheaths includes the following steps:

[0035] S1. Prepare materials: Put the different materials required for the masterbatch of cable sheaths into the corresponding material boxes 21 respectively;

[0036] S2. Feed materials: Start the stirring mechanism. The stirring shaft 12 drives the extrusion disc 25 to rotate synchronously. The material blocking member 23 is opposite to the notch 251. The reset member 24 drives the material blocking member 23 to extend out of the notch 221 to open the material outlet. A plurality of material outlets are opened in sequence to feed materials into the tank body 11 in batches.

[0037] In the masterbatch dispensing device of this technical solution, when the stirring mechanism mixes the materials inside the tank body 11, it drives the extrusion disc 25 to rotate synchronously. The rotating extrusion disc 25 cooperates with the material blocking member 23. The material blocking member 23 abuts against the extrusion disc 25 to close the material outlet. The material blocking member 23 is opposite to the notch 251. The reset member 24 drives the material blocking member 23 to extend out of the notch 221 to open the material outlet. A plurality of material outlets are opened in sequence to feed materials into the tank body 11 in batches, and the materials required for the product are fed in batches in sequence, realizing the dispensing setting of the premix during product production, ensuring the uniform and loose mixing of the premix, and completing the quality control of the premix.

[0038] To meet the needs of the material blocking member 23 for blocking materials and the requirements for the cooperative setting of the material blocking member 23 and the extrusion disc 25, as Figure 3 、 Figure 4 shown, the material blocking member 23 includes a material blocking disc 231 that matches the material pipe 22. The material blocking disc 231 is connected with an extrusion plate 232. The movable end of the extrusion plate 232 passes through the notch 221 to cooperate with the extrusion disc 25. When the material blocking disc 231 matches the material pipe 22 and the extrusion plate 232 abuts against the extrusion disc 25, the edge of the material blocking disc 231 completely abuts against the inner wall of the material pipe 22, and the material port is closed. When the extrusion plate 232 is opposite to the notch 251 and there is a gap between the edge of the material blocking disc 231 and the inner wall of the material pipe 22, the material port is opened.

[0039] To prevent materials from accumulating on the material blocking disc 231, the height of the upper end surface of the material blocking disc 231 decreases successively from the side close to the extrusion plate 232 to the side far from the extrusion plate 232. The materials accumulated on the material blocking disc 231 slide from the side with a higher upper end surface to the side with a lower upper end surface and are discharged from the material port, avoiding the generation of dead corners in material discharging.

[0040] To meet the setting requirements for the reset member 24 to drive the material blocking member 23 to extend out of the notch 221 to open the material port, as Figure 2 、 Figure 3 shown, the reset member 24 includes a first side plate 241 connected to the outer wall of the material pipe 22 and a second side plate 242 connected to the extrusion plate 232. A spring 243 is arranged between the first side plate 241 and the second side plate 242.

[0041] When the extrusion plate 232 corresponds to the notch 251 and the extrusion plate 232 is no longer under the extrusion action of the extrusion disc 25, under the action of the spring 243, the extrusion plate 232 and the material blocking disc 231 are driven to move towards the direction of the stirring shaft 12, so that a distance is generated between the material blocking disc 231 and the material pipe 22, realizing the opening of the material port.

[0042] To further improve the material distribution effect and ensure the uniformity of the premix, as Figure 2 、 Figure 3 shown, the reset member 24 further includes a screw 244. The screw 244 is in threaded cooperation with a threaded hole formed on the side wall of the tank body 11. One end of the screw 244 movably passes through the first side plate 241 and the second side plate 242 and is connected with a block 245.

[0043] The setting of the screw rod 244 controls the length of its extension into the interior of the tank body 11 by rotating the screw rod 244, and restricts the distance between the second side plate 242 and the stirring shaft 12 through the block 245, that is, restricts the distance between the material blocking disc 231 and the material pipe 22, thereby changing the size of the material opening; in this embodiment, the size of the material opening is adjusted according to the opening time of the material opening and the total amount of the material, so that the proportion of different materials input at one time is consistent with the proportion of different total amounts of materials, ensuring uniform and loose mixing of the materials.

[0044] As Figure 1 , Figure 2 shown, the cable sheath masterbatch feeding device further includes a number of cloth pieces equal to that of the material pipes 22, and multiple groups of cloth pieces are distributed in sequence in the up and down direction. The cloth piece includes two first air pipes 31 that are connected to the tank body 11 in a penetrating manner. The two first air pipes 31 are distributed oppositely. In a group of cloth pieces, a blower 32 is provided on one of the first air pipes 31 located on one side of the corresponding material pipe 22, and an exhaust fan 33 is provided on the other first air pipe 31. Refer to Figure 2 , taking the left material pipe 22 as an example, for the first group of cloth pieces corresponding to the upper part, the blower 32 is provided on the left first air pipe 31, and the exhaust fan 33 is provided on the right first air pipe 31.

[0045] In this technical solution, according to the rotation speed of the extrusion disc 25, the number of the material pipes 22, and the distance between adjacent material pipes 22, the opening time of the material opening is calculated, and the working time of the blower 32 and the exhaust fan 33 corresponding to the material pipe 22 is set according to the opening time of the material opening, so that when the material opening is opened for feeding, the cloth pieces carry out the cloth work synchronously.

[0046] When the material opening of the material pipe 22 is opened, the corresponding cloth piece starts to work. Refer to Figure 2 , taking the left material pipe 22 as an example, the blower 32 and the exhaust fan 33 are started, and the air flow moves to the right, driving the material falling from the material opening to move to the right. The setting of the cloth piece increases the distribution area of the material when the material is put into the interior of the tank body 11, improves the feeding effect of the feeding device in this technical solution, and is beneficial to the uniform and loose mixing of the premix.

[0047] In order to prevent impurities from entering the interior of the tank body 11 through the first air pipe 31, as Figure 1 shown, the movable ends of the two first air pipes 31 are connected through a second air pipe 34. The first air pipe 31, the second air pipe 34, the first air pipe 31 and the tank body 11 form a gas circulation path. At the same time, in order to prevent the material from entering the interior of the first air pipe 31, a filter screen is provided at the end where the first air pipe 31 is connected to the tank body 11.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
