Description

Technical Field

[0001] The utility model relates to the technical field of block forming equipment, in particular to a plate feeding device of a block forming machine suitable for bottom shaping. Background Art

[0002] A concrete block forming machine is a machine that produces new wall blocks by adding a small amount of cement to materials such as sand, gravel, and fly ash. The new concrete blocks produced have the characteristics of high strength, easy masonry, good wall flatness, and high construction efficiency. The block forming machine includes a frame, a pressure head assembly, a vibration system, a plate feeding mechanism, and a material distribution vehicle device. The plate feeding mechanism transports the pallet to the top of the vibration system. The concrete raw materials enter the aggregate bin through a conveyor. The raw materials are transported to the top of the vibration system by a material vehicle, and after being vibrated and formed, they are transported to the next step. Existing plate feeding devices generally use chain transmission. The transmission chain is in a tensioned state and drives the movable frame to move back and forth. Especially under certain special operating conditions, such as when used in conjunction with the vibration system of the block forming machine, the vibration of the vibration system will be transmitted to the drive assembly that drives the movable frame to move back and forth, causing damage to the drive assembly and shortening the service life of the equipment.

The bottom molding mechanism 3 is installed at one end of the movable frame 2, and a plurality of one-way pushing components 201 are provided on the movable frame 2. The one-way pushing component 201 has a pushing head 20111 facing the bottom molding mechanism 3. A pallet supporting surface is provided on the top of the frame 1, and the pallet supporting surface is placed below the bottom molding mechanism 3. The plate feeding device of this embodiment can perform continuous operation, has a fast plate feeding speed, and can perform bottom molding operations.

[0028] In this embodiment, the driving mechanism includes a reduction motor 101, a driving gear 102 and a rack 103. The reduction motor 101 is installed on the frame 1, and the driving gear 102 is transmission-connected to the output end of the reduction motor 101. One end of the rack 103 is hinged to the end of the movable frame 2 close to the bottom molding mechanism 3 and meshed with the driving gear 102. The reduction motor 101 has two output ends, each of which is transmission-connected with a driving gear 102, and each of the driving gears 102 is meshed with a rack 103. One end of the rack 103 is hinged to the movable frame 2. The reduction motor 101 of this embodiment is composed of a servo motor and a reduction mechanism. The servo motor drives the movable frame 2 to run accurately and quickly, ensuring that the bottom molding mechanism 3 and the pallet move forward or backward one pallet position each time.

[0029] The bottom molding mechanism 3 of this embodiment includes a molding plate 302 (molding not shown) connected to the top of the movable frame 2. The bottom molding mechanism 3 performs molding operations on the molding plate 302. The top of the molding plate 302 is provided with predetermined patterns and other structures.

[0030] The two ends of the frame 1 of this embodiment are respectively an upper plate end and a lower plate end, and the upper part of the frame 1 is provided with two opposite slide grooves 104, and the two sides of the movable frame 2 are respectively provided with a plurality of rollers 202, and the rollers 202 roll with the slide grooves 104 on the corresponding sides, and the bottom molding mechanism 3 is arranged near the lower plate end. The upper plate end of the frame 1 is provided with two upper plate rails 105, and one end of the movable frame 2 close to the upper plate end of the frame 1 extends between the two upper plate rails 105. There are one-way pushing components 201 distributed in pairs on the movable frame 2 between the two upper plate rails 105, and the one-way pushing components 201 include a pushing block 2011, a first limiting block 2012 and a second limiting block 2013. The pushing block 2011 is rotatably mounted on the movable frame 2, and the pushing block 2011 is tilted. The first limiting block 2012 and the second limiting block 2013 are respectively mounted on the high end, The lower end of the push block 2011 is on the inner wall of the movable frame 2, and the lower end of the push block 2011 is in contact with the second limit block 2013. The upper end of the push block 2011 is provided with a push head 20111 facing the push head 20111 of the bottom molding mechanism 3. When the pallet is transported, the pallet is pushed in by the upper plate track 105, and the servo motor is started to drive the movable frame 2 to move a distance toward the lower plate end of the frame 1. The push block 2011 is in contact with the side of the pallet to move the pallet toward the machine. The lower plate end of the frame 1 is pushed the same distance, and then the servo motor drives the movable frame 2 to move toward the upper plate end of the frame 1, and the high end of the push block 2011 deflects to the low position until the push block 2011 abuts against the side of the next pallet.

[0033] S2, molding operation: When the movable frame 2 pushes the bottom molding mechanism 3 and the supporting plate to the top of the vibration system (the molding plate 302 and the supporting plate are supported on the workbench of the vibration system), the bottom molding mechanism 3 remains in this position, and the molding operation is performed on the bottom molding mechanism 3. Specifically, the mold frame moves down and sticks to the molding surface of the bottom molding mechanism 3, and then the material is placed, pressed and vibrated.

[0034] S3, after the vibration molding is completed, the mold frame located above the bottom molding mechanism 3 is slightly lifted, the movable frame 2 drives the bottom molding mechanism 3 to retreat, and the finished building block falls onto the support plate;

[0035] S4, the movable frame 2 pushes the bottom molding mechanism 3 and the next pallet to the top of the vibration system, and at the same time puts a new pallet onto the pallet supporting surface of the frame 1, and returns to S2 for molding operation, and repeats the operation.
