[0024] The housing 1 has a blanking plate 3 at one end and a pressure plate 11 at the other end. A blanking plate 12 and a pressure plate 13 are sequentially arranged between the blanking plate 3 and the pressure plate 11. A stirring rod 5 is arranged at the axis of the blanking plate 3, and a blanking hole 52 is opened on the stirring rod 5.

[0025] The feeding unit 4 is disposed in the housing 1 and includes a pressing block 41 and a feeding pipe 47 and a guide sleeve 46 sequentially disposed on the pressing block 41. The feeding pipe 47 is connected to the feeding hole 52 and the pressure plate 13. A screw 43 engaged with the stirring rod 5 is rotatably disposed in the guide sleeve 46. The screw 43 is provided with an extrusion rod 45 that cooperates with the pressure plate 13.

[0026] The driving unit 2 is arranged on one side of the casing and cooperates with the stirring rod 5.

[0027] Specifically, one end of the housing 1 is Figure 2 shown above, while the other end refers to Figure 2 As shown below, a blanking plate 3 is set above to guide the raw material powder into the shell 1, and the side pressure plate 13 below is used to detect the pressure required for the resistor forming. A blanking plate 12 and a pressure plate 13 are sequentially arranged between the blanking plate 3 and the pressure plate 11. A stirring rod 5 is set at the axis of the blanking plate 3. A blanking hole 52 is opened on the stirring rod 5. The pressing block 41 specifically slides in the shell 1. The feeding unit 4 includes a pressing block 41 and a blanking pipe 47 and a guide sleeve 46 sequentially arranged on the pressing block 41. The blanking pipe 47 is connected to the blanking hole 52 and the pressure plate 13, and a screw 43 engaged with the stirring rod 5 is rotatably arranged in the guide sleeve 46, and the screw 43 is provided with an extrusion rod that cooperates with the pressure plate 13. The rod 45 and the pressing block 41 specifically slide in the shell 1, and the driving unit 2 is arranged on one side of the shell and cooperates with the stirring rod 5. The driving unit 2 is used to make the stirring rod 5 rotate on the discharge tray 12, so that the raw material powder between the discharge tray 12 and the discharge plate 3 is fully stirred and mixed. During the stirring process, the powder will fall from the discharge pipe 47 along the discharge hole 52 to the pressure measuring plate 13 and accumulate on the pressure measuring plate 13. The pressing block 41 is pushed to make the screw 43 engage with the stirring rod 5 so that the extrusion rod 45 slides in the guide sleeve 46, so that the pressure plate 13 interacts axially downward to extrude the raw material powder, thereby forming it into a cylindrical resistor, thereby improving the processing efficiency and quality of the resistor.

[0028] As an embodiment further provided by the present invention, a support frame 42 is clamped on the screw 43, and a triangular inclined portion 421 is provided on the support frame 42 to match the shell 1. A second spring 44 is provided between the support frame 42 and the guide sleeve 46. When the pressing block 41 is pushed into the shell 1, the support frame 42 slides downward through the triangular inclined block and squeezes the spring, so that the clamping portion 431 of the screw 43 is clamped into the stirring rod 5, thereby improving the linkage effect of the stirring rod 5 and the screw 43. When the stirring rod 5 and the screw 43 are When the rod 43 needs to be separated, the pressing block 41 is slid away from the shell 1, so that the triangular inclined portion 421 is fitted with the shell 1, so that the screw 43 is separated from the stirring rod 5, and one end of the screw 43 is provided with a clamping portion 431 to engage with the stirring rod 5, and the other end is provided with a threaded portion 432 to be threadedly connected to the extrusion rod 45, so that when the screw 43 rotates, it will drive the extrusion rod 45 to slide downward in the axial direction so that the locking portion 451 is connected to the pressure plate 13, and the pressure plate 13 interactively extrude the raw material powder downward.

[0029] As an embodiment further provided by the present invention, rubber rings 471 are provided at both ends of the discharge tube 47. The rubber rings 471 improve the sealing between the discharge tube 47 and the stirring rod 5 and the pressure plate 13, reducing the leakage of raw materials affecting the quality of the resistor. At the same time, when the stirring rod 5 rotates, the discharge tube 47 will be linked to rotate, reducing the raw materials from adhering to the inner wall of the discharge tube 47.

[0030] As an embodiment further provided by the present invention, a conical groove 121 is provided on the discharge tray 12, and a swing frame 51 that cooperates with the conical groove 121 is provided in a circular array on the stirring rod 5. The conical groove 121 cooperates with the discharge hole 52. The conical groove 121 makes the discharge of the raw material powder smoother, and the swing frame 51 will continuously scrape the conical groove 121 when rotating to prevent the raw material from adhering to the discharge tray 12, and the bottom of the conical angle of the conical hole is flush with the discharge hole 52.

[0031] As an embodiment further provided by the present invention, the drive unit 2 also includes a bracket 22, a first synchronous wheel 25 and a second synchronous wheel 27 engaged with the stirring rod 5. The bracket 22 is provided with a motor 21, and the output end of the motor 21 is provided with an extension shaft 23. The first synchronous wheel 25 is engaged with the end of the extension shaft 23. A synchronous belt 26 is provided between the first synchronous wheel 25 and the second synchronous wheel 27. The bracket 22 is fixed to one side of the shell 1. The model of its motor 21 is MHMF042L1U2M2. The motor 21 is used as a power device to make the extension shaft 23 drive the first synchronous wheel 25 to rotate, and the first synchronous wheel 25 drives the second synchronous wheel 27 to rotate in conjunction with the stirring rod 5 through the synchronous belt 26.

[0032] As an embodiment further provided by the present invention, a material discharge hopper 31 is provided on the material discharge tray 12 . The material discharge hopper 31 increases the material discharge speed and can hold the raw materials required for the resistor sheet at one time, so that the raw materials can enter the housing 1 better.

[0033] As an embodiment further provided by the present invention, a clamping block 131 is symmetrically arranged on the pressure plate 13, and a first spring 132 is arranged between the clamping block 131 and the pressure plate 13. When the extrusion rod 45 pulls the pressure plate 13 to slide upward, the elastic force of the first spring 132 pushes the clamping block 131 to cooperate with the shell 1, so that the extrusion plate 13 can be better separated from the pressure plate 13, and at the same time, the pressure plate 13 can return to its initial position before extrusion after each extrusion is completed.

[0034] As a further embodiment provided by the present invention, a pressure value meter 112 is provided on the pressure measuring plate 11 . When the pressure plate 13 slides axially downward to extrude the raw material powder, the extrusion force will be displayed on the pressure value meter 112 .

[0035] Working principle: First, various resistor raw material powders are poured from the discharge hopper 31 and piled onto the discharge tray 12. At the same time, the motor 21 rotates, and the extension shaft 23 provided at the output end of the motor 21 rotates the first synchronous wheel 25 through the synchronous belt 26 to link the second synchronous wheel 27 to rotate, thereby rotating the stirring rod 5. The raw material powders are fully mixed under the continuous stirring of the swing frame 51. Then the stirred powders slide from the discharge pipe 47 along the discharge hole 52 to the pressure plate 11 and accumulate. When the raw material powders slide into the pressure plate, the pressure plate is pushed and pressed. The block 41 enables the engaging portion 431 at one end of the screw 43 to engage with the stirring rod 5, thereby linking the screw 43 to rotate on the guide sleeve 46 through the stirring rod 5, so that the extrusion rod 45 slides axially along the guide sleeve 46 and pushes the pressure plate 13 to extrude the accumulated raw material powder. At the same time, during the extrusion molding process, the extrusion pressure value of the pressure plate 13 can be observed by the pressure value meter 112, so that the extrusion force exerted on each resistor sheet during molding is the same, thereby improving the production efficiency of the resistor sheet and preventing the problem of raw material loss during multiple transportations.
