[0030] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] Those skilled in the art will readily appreciate other embodiments of the present invention after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses or adaptations of the present invention, which follow the general principles of the present invention and include common knowledge or customary technical means in the art not disclosed in this disclosure.

[0032] To this end, some embodiments of the present application provide a cable extruder hopper assembly such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes an upper hopper 1, a lower hopper 2, and a gate valve 3 between the upper hopper 1 and the lower hopper 2. The upper hopper 1 includes a first barrel portion 101 and a first cone portion 102 connected below the first barrel portion 101, and the lower hopper 2 includes a second cone portion 201 and a second barrel portion 202 connected below the second cone portion 201. The first cone portion 102 has a first flange 120 with a first inclination angle, and the first flange 120 has, for example, a first oblique opening 121, and the second cone portion 201 has a second flange 210 with a first inclination angle, and the second flange 210 has a second oblique opening 211 corresponding to the position of the first oblique opening, and the connection between the upper hopper 1 and the lower hopper 2 is achieved after the first flange 120 and the second flange 210 are butted.

[0033] The gate valve 3 is fitted between the first oblique opening 121 and the second oblique opening 211 at the first inclination angle to disconnect or connect the first cone portion and the second cone portion. Figure 4 The slot shown is matched to provide an opening and closing surface between the upper hopper and the lower hopper on the first flange 120 or the second flange 210. For example, the second flange 210 has a transverse through slot 212 to accommodate the insert plate 31, so that the insert plate 31 can move in the slot 212, that is, Figure 6 , Figure 7 The upward or downward movement in the middle opens and closes the communication between the first oblique opening 121 and the second oblique opening 211, that is, the two are aligned (opened) or the two are not aligned (closed). The notch 212 can also be opened on the upper flange or half of the upper flange and the lower flange, or in other ways.

[0034] like Figure 5As shown, one or both of the first oblique opening 121 and the second oblique opening 211 may be one or more first raw material passage holes, for example, the first oblique opening 121 is rectangular, the second oblique opening 211 is circular, and the area of ​​the second oblique opening 211 is smaller than that of the first oblique opening 121, thereby forming a first raw material passage in the upper hopper 1 and the lower hopper 2. Figure 5 As shown, the insert plate 31 may have a second raw material passage hole 311 corresponding to the first raw material passage hole 211, and the positions of the first raw material passage hole 211 and the second raw material passage hole 311 are determined to allow the first raw material passage hole and the second raw material passage hole to be misaligned when the insert plate 31 is in the closed position, such as Figure 7 As shown, Figure 6 As shown, when the insert plate 31 is in the open position, the first raw material passage hole 211 and the second raw material passage hole 311 are aligned to allow the raw material to pass through. In other embodiments, the second oblique opening 211 can be in the form of multiple, for example, three first raw material passage holes, the first oblique opening 121 is also a rectangular opening, and the insert plate 31 has three second raw material passage holes 311 of the same size as the first raw material passage hole 211. It should be understood that the size of the second raw material passage hole 311 can be the same as or different from the size of the first raw material passage hole 211. In other embodiments, such as Figure 8 As shown, the insert plate 31 can also be a plate without holes, so that the insert plate 31 covers the second inclined opening 211, that is, the position of the first raw material channel hole, when it is closed, and the first raw material channel hole is opened only when the insert plate 31 is driven so that its edge moves away from the second inclined opening 211, that is, the position of the first raw material channel hole.

[0035] In another embodiment, if Fig. 9 As shown, the insert plate 31 can be composed of a handle 312 and a main body 313 enlarged relative to the handle, wherein the second raw material channel hole 311 is arranged on the main body 313, the handle 312 is connected to the driving unit and the main body 313 cooperates with the upper hopper 1 and the lower hopper 2, and the driving unit drives the handle and the main body 313 to move relative to the upper hopper 1 and the lower hopper 2 to achieve the connection and disconnection of the first raw material channel hole 211 and the second raw material channel hole 311.

[0036] The area of ​​the first oblique opening 121 is smaller than that of the second oblique opening 211 so that the lowermost end of the first cone portion 102 is located within the range of the second cone portion 201. This arrangement allows the old material in the upper hopper to be completely emptied when replacing the material without leaving any residual material, creating favorable conditions for producing high-quality cables.

[0037] In the first cone portion 101 of the upper hopper 1, a discharge pipe 51 is preferably provided at a height position close to the gate valve 3, and a discharge valve 5 is provided on the discharge pipe 51 to close or open the discharge pipe 51. The discharge valve 5 can be, for example, a manual discharge valve or an electric discharge valve or a pneumatic discharge valve. The discharge hand valve is installed on the discharge pipe, and the discharge pipe is at the lowest point of the upper hopper. When the production line is to stop production, the hand valve is started, the cylinder rod is extended to separate the upper and lower hoppers, and then the discharge pipe hand valve is opened to release all the stored materials in the upper hopper. The present application takes into account the connection between the upper hopper and the lower hopper, and sets the discharge pipe at the lowest point of the upper hopper to ensure that no material is stored. The discharge pipe can be set at a variety of angles, preferably inclined at the first inclination angle.

[0038] A lower hopper 2 is provided, and the volume relationship between the upper hopper and the lower hopper can be designed according to the needs to ensure that the user has enough time to replace the material package. The weight of the cable material is calculated according to the volume, and the weight of the upper hopper and the lower hopper themselves is calculated. The optimal result is obtained according to the material mechanics calculation, so that the upper hopper and the lower hopper can not only meet the safety of the equipment use, but also save raw materials and investment as much as possible.

[0039] The gate valve 3 can be, for example, a manual gate valve, a pneumatic gate valve or an electric gate valve. Taking the pneumatic gate valve as an example, it includes a gate 31 and a cylinder 32 as a driving unit to control the movement of the gate. The cylinder 32 can use a high-power cylinder as a power output, and the weight of the cable material can be calculated according to the volume of the upper hopper and the lower hopper, thereby determining the model of the cylinder. The cylinder is matched with a pneumatic unit 4, which can be composed of components such as an air source component 41, a manual valve 42 and an air pipe 43. The air source component 41 is connected to the cylinder 32 through the manual valve 42 and the air pipe 43. The manual valve 42 controls the air source component to drive the cylinder rod of the cylinder 32 of the pneumatic gate valve to extend or retract to drive the movement of the gate 31, thereby realizing the switch control of the connection between the upper hopper and the lower hopper. It should be understood that in the manual and electric variants, the driving unit is a hand or a motor.

[0040] In some embodiments, an upper material level detection switch 61 and a lower material level detection switch 62 may be installed at different heights of the upper hopper to monitor the material amount in the upper hopper in real time to ensure that the material amount in the hopper is within a reasonable range.

[0041] In some embodiments, an observation window 7 may be installed on the side wall of the upper hopper and / or the lower hopper. Preferably, the observation window is widened so that the amount of cable material in the hopper can be observed from multiple angles, thus playing a double insurance role.

[0042] A gate valve observation window 8 installed on the pneumatic gate valve can be provided, so that the state of the gate can be checked at any time, such as whether it is in a closed state or an open state, so as to avoid the occurrence of misoperation.

[0043] It will be appreciated that the present invention is not limited to the exact construction that has been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof.
