Description

Technical Field

[0001] This utility model relates to the field of fiber-reinforced calcium silicate board processing technology, and in particular to a raw material crushing and mixing device for fiber-reinforced calcium silicate board processing. Background Technology

[0002] Currently, the processing of asbestos-free fiber reinforced calcium silicate boards requires mixing raw materials. However, the commonly used raw material mixing equipment for processing asbestos-free fiber reinforced calcium silicate boards has a simple structure and does not properly crush the raw materials. During the mixing process, due to the uniform size of the raw material particles, larger particles tend to settle at the bottom of the mixer, making it difficult to mix evenly. This reduces efficiency and also lowers the quality of the finished asbestos-free fiber reinforced calcium silicate board.

[0003] In the existing technology patent CN212092048U, a raw material crushing and mixing device for processing asbestos-free fiber reinforced calcium silicate board is disclosed. Through the coordinated use of a sleeve, a second rotating shaft, a first crushing blade, a belt, a fixing frame, a first motor, a connecting shaft, a housing, and a second crushing blade, the device achieves high mixing efficiency for raw material crushing and mixing in the processing of asbestos-free fiber reinforced calcium silicate board. This solves the problem of low mixing efficiency in general raw material crushing and mixing devices for processing asbestos-free fiber reinforced calcium silicate board. It can crush larger raw materials before mixing them, thereby improving the mixing efficiency of raw materials and improving people's work efficiency, further meeting people's needs.

[0004] However, in the aforementioned existing technology patents, the raw materials are crushed only by crushing blades, which can easily result in some raw materials not being completely crushed, affecting subsequent processing. Utility Model Content

Two crushing rollers 105 are fixedly connected to the corresponding first rotating shaft 109 and respectively sleeved on the outer wall of the first rotating shaft 109. The fixed seat 106 has a cavity 111 and a discharge hole 112. The discharge hole 112 communicates with the cavity 111. The second rotating shaft 110 is rotatably connected to the fixed seat 106 and located inside the cavity 111. Two crushing teeth 107 are fixedly connected to the fixed seat 106 and are both located inside the cavity 111. The crushing wheel 108 is fixedly connected to the second rotating shaft 110 and sleeved on the outer wall of the second rotating shaft 110.

[0021] In this embodiment, during use, the raw material is fed into the feed pipe 103 and falls into the two crushing rollers 105. The first motor 124 drives the first rotating shaft 109 to rotate the crushing rollers 105, and the raw material is initially crushed by the crushing rollers 105. Then, the raw material enters the cavity 111 of the fixed base 106. The second rotating shaft 110 in the cavity 111 drives the crushing wheel 108 to rotate. The raw material is then crushed a second time by the cooperation of the crushing teeth 107 and the crushing wheel 108. Then, the raw material enters the bottom through the discharge hole 112 and is then mixed by the stirring assembly. In this way, the raw material can be completely crushed, the mixing efficiency of the raw material is increased, and it is beneficial to subsequent processing.

[0022] Furthermore, the crushing assembly also includes an observation window 113, which is fixedly connected to the housing 102 and located on the outside of the housing 102.

[0023] In this embodiment, by opening the observation window 113 on the outside of the box 102, the observation window 113 allows personnel to easily understand the crushing of the raw materials inside the box 102, which facilitates operation.

[0024] Furthermore, the raw material crushing and mixing device for processing fiber-reinforced calcium silicate board also includes a weighing component, which is disposed inside the feed pipe 103.

[0025] In this embodiment, by setting the weighing component inside the feed pipe 103, the weighing component can accurately feed materials into the box 102 each time, which facilitates the processing of raw materials.

[0026] Furthermore, the weighing assembly includes a movable plate 114, a weight sensor 115, a spring 116, a telescopic rod 117, and a stop block 118. The movable plate 114 is rotatably disposed inside the feed pipe 103. The weight sensor 115 is fixedly connected to the movable plate 114 and located on the movable plate 114. The two ends of the spring 116 are fixedly connected to the feed pipe 103 and the movable plate 114, respectively. The telescopic rod 117 is fixedly connected to the feed pipe 103 and located on the outer side wall of the feed pipe 103. The feed pipe 103 has a groove 123. The telescopic end of the telescopic rod 117 movably passes through the groove 123. The stop block 118 is connected to the telescopic end of the telescopic rod 117 and is adapted to the groove 123.

[0027] In this embodiment, the target crushing amount of raw material is first set in the system background. Then, the staff puts the raw material into the feed pipe 103. The raw material will fall above the movable plate 114. The weight sensor 115 above the movable plate 114 will monitor the weight of the raw material in real time. When the raw material reaches the target weight, the telescopic rod 117 on the outside of the box 102 is activated. The output end of the telescopic rod 117 drives the stop block 118 into the groove 123 of the feed pipe 103. At this time, due to the effect of gravity, the movable plate 114 rotates downward in the feed pipe 103. The spring 116 is squeezed and compressed by the movable plate 114. The raw material will fall above the two crushing rollers 105 for crushing. After the feeding is completed, the spring 116 returns to tension and drives the movable plate 114 to reset.

[0028] Furthermore, the stirring assembly includes a drive shaft 119, a support plate 120, multiple connecting rods 121, and multiple stirring blades 122. The drive shaft 119 is rotatably disposed at the bottom of the housing 102. The support plate 120 is fixedly connected to the drive shaft 119.
