Technical Field

[0001] The utility model relates to the technical field of building material production equipment, in particular to a block turning and demoulding device. Background Technique

[0002] Blocks are a new type of wall material, which can be divided into solid and hollow according to their structures; among them, concrete blocks are widely used because of their easy availability of materials, high strength and light weight. The production process of concrete blocks includes steps such as batching, mixing, forming, and curing; forming is to fill the concrete into the block mould by mechanical or manual means, and after compaction and demoulding, the required shape and size are formed.

[0003] In the existing block production equipment, both compaction and demoulding are completed in the same equipment, with low production efficiency. And because the mould is installed on the production equipment, the raw materials remaining on the mould after long-term use not only affect the forming effect of the blocks, but may also damage the mould during the compaction process. For this reason, a block turning and demoulding device is proposed. Content of the Utility Model

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] Referring to Figure 1 , the present utility model provides a building block flipping and demolding device, including a flipping bracket 1. Stabilizing frames 2 are installed on both sides of the flipping bracket 1. A flipping shaft 101 and a driving shaft 102 are installed on the flipping bracket 1 from top to bottom. Driven gears 103 and driving gears 104 that mesh with each other are installed at both ends of the flipping shaft 101 and the driving shaft 102 respectively. The diameter of the driving gear 104 is larger than that of the driven gear 103. A swing arm 109 is installed on the driving shaft 102, and a strip-shaped through hole 110 along its length direction is provided on the swing arm 109.

[0018] A flipping cylinder 3 is installed on the stabilizing frame 2. A guiding column 301 is installed on the piston rod of the flipping cylinder 3. The guiding column 301 is slidably installed in the strip-shaped through hole 110. In practical applications, the position of the guiding column 301 on the piston rod of the flipping cylinder 3 is adjustable, so as to adjust the rotation angle of the swing arm 109. When the swing arm 109 rotates from one extreme position to the other extreme position, the driving gear 104 drives the driven gear to rotate 180°.

[0019] A support box 108 is installed on the flipping shaft 101. Two groups of upper support rods 107 and lower support rods 105 are installed on the support box 108. Two guiding wheels 106 are installed between the lower support rod 105 and the upper support rod 107. The distance between the two guiding wheels 106 matches the width of the mold 4. When the mold 4 is inserted between the lower support rod 105 and the upper support rod 107, the guiding wheels 106 play a role in limiting and guiding. The lower support rod 105 is hollow, and a locking mechanism that matches the positioning holes on the mold 4 is arranged inside to fix it between the lower support rod 105 and the upper support rod 107.

[0020] Referring to Figure 2, the locking mechanism includes a support 111 fixedly installed inside the support rod 105 and two groups of springs 117. A support arm 112 is installed on the support 111. The middle of the support arm 112 is rotatably connected to the support 111. Connecting forks 114 are installed at both ends of the support arm 112. A positioning pin 113 is installed inside the connecting fork 114. The two positioning pins 113 respectively penetrate the upper and lower surfaces of the lower support rod 105. The positioning pin 113 penetrating the upper surface of the lower support rod 105 is matched with the positioning hole of the mold 4. A chute 116 is provided on the connecting fork 114. A slider 115 is installed on the positioning pin 113. The slider 115 is slidably installed in the chute 116. One end of the spring 117 is connected to the inner wall of the lower support rod 105, and the other end is connected to the support arm 112.

[0021] For the convenience of understanding the present invention, the working principle of this solution is described in detail as follows: During operation, the mold 4 is conveyed by the production conveyor line 7 to the lower part of the production equipment 8, and the mold is filled with material and compacted. A baffle plate 701 is provided on the production conveyor line 7 on the other side of the production equipment 8, and a mold pushing mechanism 702 is installed on the side. The mold pushing mechanism 702 pushes the compacted mold 4 into the space between the lower support rod 105 and the upper support rod 107. A limit block 501 facing the lower support rod 105 is installed on the mold conveyor belt 5. At this time, the lower support rod 105 is in a horizontal state and is embedded in the mold conveyor belt 5. The limit block 501 contacts the positioning pin 113 passing through the lower surface of the lower support rod 105 and pushes it into the lower support rod 105. Driven by the support arm 112, the positioning pin 113 penetrating the upper surface of the lower support rod 105 retracts into the lower support rod 105 to facilitate the insertion of the mold 4. Figure 3 During the rotation of the swing arm 109 driven by the flipping cylinder 3, the support box 108 is driven to rotate. After the lower support rod 105 is separated from the contact with the limit block 501, under the action of the spring 117, the positioning pin 113 pops out and inserts into the positioning hole of the mold 4 to fix it. The support box 108 rotates 180° to invert the mold 4 onto the block conveyor belt 6, and the blocks inside it fall out of the mold 4 onto the block conveyor belt 6 and are transported to the next process.

[0022] After the mold 4 that has been demolded is flipped back onto the mold conveyor belt 5, the next mold 4 ejects the demolded mold 4 from between the lower support rod 105 and the upper support rod 107. The demolded mold 4 enters the cleaning equipment with the mold conveyor belt 5 for cleaning and is then transported back to the production conveyor line 7 for reuse.
