Description

Technical Field

[0001] This utility model relates to the field of bulletproof ceramic molding technology, and in particular to an automatic feeding device for bulletproof ceramic molding molds. Background Technology

[0002] Bulletproof ceramic is a high-hardness, high-durability ceramic material primarily used in military, police, civilian, and nuclear industries. Its main characteristics are excellent ballistic protection and lightweight properties, making it an indispensable part of modern military equipment. Bulletproof ceramic is typically manufactured using molds to shape it.

[0003] Chinese utility model patent CN222406316U discloses a bulletproof ceramic molding die, including a base for mounting a device. Mounting mechanisms are provided on both sides of the base, and a grouting mechanism for injecting slurry is provided above the base. Each mounting mechanism includes a threaded block and a connecting rod. The threaded block is fixedly mounted on one end of the connecting rod and is threadedly connected to the inner wall surface of the base. This bulletproof ceramic molding die, by incorporating the mounting mechanism, solves the problem of previous bulletproof ceramic molding dies being difficult to replace templates, limiting the device to molding only bulletproof ceramics of a single shape and thickness. When different shapes or thicknesses of bulletproof ceramics need to be manufactured, other devices are required, easily increasing manufacturing costs and affecting manufacturing efficiency. This new die allows for the removal and replacement of templates of different shapes from the device, effectively completing the bulletproof ceramic manufacturing process and reducing manufacturing costs.

[0004] With the diversification of bulletproof ceramic products, the shapes and structures of existing bulletproof ceramic molding dies are becoming increasingly complex. For some dies with special structures, such as dies with complex internal irregular surfaces, traditional feeding methods cannot ensure that the raw materials can be evenly filled into all corners of the dies, which can easily lead to insufficient filling or local accumulation, affecting the molding quality of the products. Therefore, there is a problem of not being able to feed materials into the dies. Utility Model Content

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This is the first embodiment of the present invention. This embodiment provides an automatic feeding device for bulletproof ceramic molding mold, including a base 1. An adjustment mechanism 3 is slidably connected to the outer surface of the base 1. A feeding mechanism 2 is fixedly connected to the outer surface of the adjustment mechanism 3. A control panel 4 and a lower mold 7 are fixedly connected to the upper surface of the base 1. The feeding mechanism 2 includes a spiral conveying shell 204 fixedly connected to the outer surface of the movable frame 304. A discharge port is opened on the lower surface of the spiral conveying shell 204. A first baffle plate 207 and a second baffle plate 209 are slidably connected to the outer surface of the spiral conveying shell 204.

[0034] Specifically, a first electric telescopic rod 208 is fixedly connected to the outer surface of the spiral conveyor housing 204. The output end of the first electric telescopic rod 208 is fixedly connected to the outer surface of the second baffle plate 209. A second electric telescopic rod 210 is also fixedly connected to the outer surface of the spiral conveyor housing 204. The output end of the second electric telescopic rod 210 is fixedly connected to the outer surface of the first baffle plate 207. A limit rod 205 is fixedly connected to the outer surface of the spiral conveyor housing 204. A sliding block 206 is slidably connected to the outer surface of the limit rod 205. The outer surface of the sliding block 206 is fixedly connected to the outer surfaces of the first baffle plate 207 and the second baffle plate 209, respectively. A fixed bracket is fixedly connected to the upper surface of the base 1. A storage bin 202 is slidably connected to the upper surface of the fixed bracket. A first pulley 203 is fixedly connected to the lower surface of the storage bin 202. The first pulley 203 is slidably connected to the upper surface of the base 1. A conveying pipe 201 is fixedly connected to the inner wall of the first pulley 203. The lower surface of the conveying pipe 201 is fixedly connected to the inner wall of the spiral conveying shell 204. A drive motor 212 is fixedly connected to the outer surface of the spiral conveying shell 204. A spiral shaft 211 is fixedly connected to the output shaft of the drive motor 212. The outer surface of the spiral shaft 211 is rotatably connected to the inner wall of the spiral conveying shell 204.

[0035] Furthermore, the position of the spiral conveyor shell 204 is precisely adjusted by the adjustment mechanism 3, and the size of the discharge port is adjusted by the first electric telescopic rod 208 and the second electric telescopic rod 210. This allows for accurate control of the feeding position and flow rate of the raw materials according to different molding requirements, ensuring the uniform distribution of bulletproof ceramic raw materials in the mold and effectively improving the quality stability of bulletproof ceramic products.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The adjustment mechanism 3 includes a movable frame 304 that is slidably connected to the upper surface of the base 1. A connecting block 302 is fixedly connected to the lower surface of the movable frame 304. A threaded rod 307 is threadedly connected to the outer surface of the connecting block 302.

[0038] The specific adjustment mechanism 3 also includes a servo motor 301 fixedly connected to the lower surface of the base 1. The output shaft of the servo motor 301 is fixedly connected to the outer surface of the threaded rod 307. The other end of the threaded rod 307 is rotatably connected to a fixing block 303. The outer surface of the fixing block 303 is fixedly connected to the lower surface of the base 1. The other end of the spiral conveying housing 204 is fixedly connected to a support frame 305. The outer surface of the support frame 305 is rotatably connected to a second pulley 306. The lower surface of the second pulley 306 is slidably connected to the upper surface of the base 1. The upper surface of the fixing frame is fixedly connected to a hydraulic telescopic rod 5. The output end of the hydraulic telescopic rod 5 is fixedly connected to an upper mold 6.

[0039] The addition of the support frame 305 and the second pulley 306 increases the stability of the screw conveyor housing 204 during material discharge, reducing shaking and vibration during operation. The synchronous sliding design of the storage bin 202 and the screw conveyor housing 204, along with the use of the first pulley 203, reduces friction, allowing the equipment to adjust the feeding position more flexibly, improving overall operating efficiency, and extending the equipment's service life.

[0040] Working Principle: The operator starts the servo motor 301 via the control panel 4. The output shaft of the servo motor 301 begins to rotate, driving the threaded rod 307, which is fixedly connected to it, to rotate synchronously. Since the threaded rod 307 is threadedly connected to the connecting block 302, the connecting block 302 moves along the axial direction of the threaded rod 307 when the threaded rod 307 rotates. The connecting block 302 is fixed to the lower surface of the moving frame 304, so the movement of the connecting block 302 will cause the moving frame 304 to slide on the upper surface of the base 1. The moving frame 304 is fixedly connected to the spiral conveying housing 204 of the feeding mechanism 2, so the movement of the moving frame 304 further drives the spiral conveying housing 204 to move to the appropriate feeding position. At the same time, the support frame 305 and the second pulley 306 at the other end of the spiral conveying housing 204 also move with it. The second pulley 306 slides on the upper surface of the base 1, which not only reduces the friction between the support frame 305 and the base 1, but also increases the stability of the spiral conveying housing 204 during movement and discharge. In addition, the storage bin 202 slides on the fixed support via the first pulley 203 and moves synchronously with the screw conveyor housing 204. The first pulley 203 reduces the friction between the storage bin 202 and the upper surface of the fixed support, ensuring that the storage bin 202 and the screw conveyor housing 204 can slide smoothly and synchronously, which facilitates the adjustment of the discharge position of the screw conveyor housing 204.

[0041] Next is the discharge port size adjustment stage. After the screw conveyor housing 204 moves to the predetermined position, the operator activates the first electric telescopic rod 208 and the second electric telescopic rod 210 via the control panel 4. The output end of the first electric telescopic rod 208 pushes the second baffle plate 209 to move at the discharge port of the screw conveyor housing 204, and the output end of the second electric telescopic rod 210 pushes the first baffle plate 207 to move at the discharge port. Since both the first baffle plate 207 and the second baffle plate 209 are fixedly connected to the sliding block 206, and the sliding block 206 slides on the outer surface of the limiting rod 205, the limiting rod 205 limits the movement of the first baffle plate 207 and the second baffle plate 209, ensuring that they can move smoothly and accurately. By adjusting the positions of the first baffle plate 207 and the second baffle plate 209, the size of the discharge port on the lower surface of the spiral conveyor housing 204 can be precisely controlled, thereby ensuring that the bulletproof ceramic raw material is evenly fed into the lower mold 7 according to actual needs. After the discharge port size is adjusted, the operator starts the drive motor 212. The output shaft of the drive motor 212 drives the spiral shaft 211 to rotate on the inner wall of the spiral conveyor housing 204. The rotation of the spiral shaft 211 generates a spiral propulsion force, pushing the raw material from the storage bin 202 into the spiral conveyor housing 204 through the conveying pipe 201 towards the discharge port, so that the raw material falls evenly into the lower mold 7 from the discharge port. When all the bulletproof ceramic raw material has been fed into the lower mold 7 as required, the operator starts the hydraulic telescopic rod 5 through the control panel 4. The output end of the hydraulic telescopic rod 5 pushes the upper mold 6 to move to the outer surface of the lower mold 7. The upper mold 6 cooperates with the lower mold 7 to apply pressure to the bulletproof ceramic raw material, thus shaping it.
