Description

Technical Field

[0001] This utility model relates to the field of feeding devices, specifically to a feeding device for silicone product manufacturing. Background Technology

[0002] In the production process of silicone products, the feeding device is a key piece of equipment used to accurately and stably add silicone raw materials into production equipment (such as mixers, extruders, molding machines, etc.).

[0003] It mainly consists of a spiral shaft, a material cylinder, a drive motor, and inlet and outlet ports. The spiral shaft is installed inside the material cylinder, and the drive motor drives the spiral shaft to rotate. The silicone raw material enters the material cylinder from the inlet port, moves forward along the material cylinder under the push of the spiral shaft, and is finally discharged from the outlet port and enters the production equipment.

[0004] In existing technologies, when silicone raw materials are stored in hoppers, they are prone to clumping due to prolonged stillness or environmental factors (such as humidity and temperature). This affects the uniformity and flowability of the silicone raw materials, thereby impacting the stability of subsequent production processes and product quality. Existing technologies may not have effective measures to prevent or reduce the clumping of silicone raw materials. During the process of conveying silicone raw materials to production equipment through conveying pipes, factors such as vibration, friction, or temperature changes during the conveying process can cause the silicone raw materials to clump again, affecting conveying efficiency and product quality. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a feeding device for silicone product production. It adds a drive motor and a stirring frame to the hopper and works with a vibrator. At the same time, a stirring rod is set in the conveying pipe. This solves the technical problems of easy agglomeration and poor dispersing effect in the storage and transportation of silicone raw materials, which affect the stability of production and product quality.

[0006] The objective of this utility model is achieved through the following means:

[0007] A feeding device for silicone product production includes a hopper and a conveying pipe. The conveying pipe is fixedly connected to one side of the outside of the hopper. A discharge pipe is vertically installed on one side of the lower end of the conveying pipe. A drive rod is rotatably installed inside the conveying pipe. Spiral conveying blades are fixedly installed on the outside of the drive rod inside the conveying pipe. Stirring rods are fixed at equal intervals on the outside of the drive rod. The lower end of the drive rod passes through and extends to the outside of the lower end of the hopper. A second drive motor is fixed to the outside of the hopper on the side outside the conveying pipe via a frame. A drive gear is fixed to the output end of the second drive motor. A transmission belt is installed on the outside of the drive gear and the drive rod. A first drive motor is fixed to the upper inside of the hopper via a frame. A stirring frame is installed at the output end of the first drive motor. Second vibrators are fixed to the left and right sides of the outside of the hopper via a frame.

[0008] Furthermore, a sleeve is installed on the lower end of the discharge pipe, and the sleeve is slidably connected to the discharge pipe, which allows the sleeve to be raised and lowered.

[0009] Furthermore, a conical shell is installed at the lower part of the sleeve, and the conical shell is fixedly connected to the sleeve through a frame.

[0010] Furthermore, a first vibrator is provided at the lower end of the conical shell, and the first vibrator is fixedly connected to the conical shell through a frame. The first vibrator is used to make the conical shell shake so as to break up the silicone raw material.

[0011] Furthermore, the upper end of the conical shell is equipped with guide vanes that are uniformly distributed along the ring, and the guide vanes are fixedly connected to the conical shell. The guide vanes are used to guide and disperse the silicone raw material.

[0012] Furthermore, the transmission belt is connected to the drive gear and the drive rod, and the transmission belt is used to transmit the motion of the drive gear to the drive rod.

[0013] The beneficial effects of this invention are as follows: by setting a first drive motor and a stirring rack inside the hopper, the silicone raw material stored in the hopper is continuously stirred and dispersed. The second vibrator further enhances the dispersion effect and prevents agglomeration. At the same time, the silicone raw material is further prevented from agglomerating by being struck by the stirring rod while being conveyed inside the conveying pipe, thus solving the problems mentioned in the background art.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] In this embodiment, refer to Figures 1-3 The specific implementation of a feeding device for silicone product production includes a hopper 1 and a conveying pipe 2. The conveying pipe 2 is fixedly connected to one side of the outside of the hopper 1. A discharge pipe 3 is vertically installed on one side of the lower end of the conveying pipe 2. A drive rod 14 is rotatably arranged inside the conveying pipe 2. Spiral conveying blades 15 are fixedly installed on the outside of the drive rod 14 inside the conveying pipe 2. Stirring rods 16 are fixed at equal intervals on the outside of the drive rod 14. The lower end of the drive rod 14 passes through and extends to the lower end of the hopper 1. A second drive motor 11 is fixed to the outside of the hopper 1 on the side outside the conveying pipe 2 via a frame. A drive gear 12 is fixed to the output end of the second drive motor 11. A transmission belt 13 is installed on the outside of the drive gear 12 and the drive rod 14. A first drive motor 8 is fixed to the upper inside of the hopper 1 via a frame. A stirring frame 9 is installed at the output end of the first drive motor 8. Second vibrators 10 are fixed to the left and right sides of the outside of the hopper 1 via a frame.

[0020] like Figure 1 and Figure 3 As shown, a sleeve 4 is installed on the lower end of the discharge pipe 3, and the sleeve 4 is slidably connected to the discharge pipe 3. The slidable connection allows the sleeve 4 to be raised and lowered.

[0021] like Figure 1 and Figure 3 As shown, a conical shell 5 is installed at the lower part of the sleeve 4, and the conical shell 5 is fixedly connected to the sleeve 4 through a frame.

[0022] like Figure 1 and Figure 3 As shown, a first vibrator 7 is provided at the lower end of the conical shell 5, and the first vibrator 7 is fixedly connected to the conical shell 5 through a frame. The first vibrator 7 is used to make the conical shell 5 shake so as to break up the silicone raw material.

[0023] like Figure 1 and Figure 3As shown, the upper end of the conical shell 5 is equipped with guide vanes 6 that are evenly distributed along the ring, and the guide vanes 6 are fixedly connected to the conical shell 5. The guide vanes 6 are used to guide and disperse the silicone raw material.

[0025] The working process of a feeding device for silicone product production in this embodiment is as follows: The raw material of the silicone product is placed in the hopper 1. The first drive motor 8 and the second vibrator 10 are started. The stirring rack 9 at the output end of the first drive motor 8 rotates and continuously stirs the silicone product to break it up. The second vibrator 10 generates vibration to improve the breaking up effect and prevent agglomeration. The discharge pipe 3 is moved to the feeding area. When feeding is required, the second drive motor 11 is started to make the drive gear 12 rotate. The drive rod 14 is driven through the transmission belt 13, which in turn makes the spiral conveying blade 15 rotate. The spiral conveying blade 15 rotates to lift the silicone raw material. With the help of the stirring rod 16, the silicone raw material is prevented from agglomerating inside the conveying pipe 2. After the silicone raw material is lifted to the top of the conveying pipe 2, it falls from the discharge pipe 3 and passes through the sleeve 4. The first vibrator 7 is started to make the conical shell 5 shake. With the help of the guide plate 6 and the vibration, the falling silicone raw material is dispersed when it falls into the feeding area, further preventing agglomeration.
