Description

Technical Field

[0001] This invention relates to the field of block forming equipment technology, and in particular to a lifting and feeding plate device and a feeding plate process. Background Technology

[0002] A block molding machine is a machine that produces new types of wall blocks using materials such as sand, gravel, and fly ash with a small amount of cement. These new concrete blocks are characterized by high strength, easy construction, good wall surface flatness, and fast construction efficiency. A block molding machine generally includes a main frame, a vibrating table, a material cart, an upper pressure head, and a material feeding cart. In the brick-making process, raw materials enter the material cart through the hopper. The material cart evenly carries the raw materials to the mold frame on the vibrating table. After the vibrating table vibrates and shapes the blocks, the brick receiving machine transports the finished product and pallet from the vibrating table to the next step. The pallet feeding device is used to transport pallets to the vibrating platform in a block forming machine. The pallet feeding device usually adopts a pitch conveying mechanism, which pushes the pallets one by one onto the vibrating table by a pitch conveying frame that is slidably mounted on the frame. Because the space at the bottom of the block forming machine is relatively small, and the height of the feeding frame is adjusted according to the height of different products, there is a risk of collision between the pallet feeding machine and the feeding frame when the pallet is transported to the vibrating platform. It is necessary to wait for the feeding frame to make room and adjust before the pallet feeding action can be carried out, which reduces the work efficiency. If the collision is avoided by adjusting the height of the pitch conveying frame, it will increase the manufacturing difficulty of the equipment. Summary of the Invention

[0003] To overcome the technical defects of the existing technology, the present invention provides a lifting and feeding device that can achieve avoidance action through simple operation, ensure feeding efficiency, and has a simple structure.

[0004] The technical solution adopted in this invention is: a lifting and feeding device, including a frame, a pitch conveyor frame slidably mounted on the frame, and a drive mechanism for driving the pitch conveyor frame to move. The front part of the frame is provided with a lifting frame, the rear end of the lifting frame is hinged to the frame, and the front end of the lifting frame is provided with a lifting drive part for swinging the lifting frame up and down around the rear end of the lifting frame. The front end of the pitch conveyor frame is connected to an upper plate frame, and the feeding surface of the upper plate frame is higher than the feeding surface of the pitch conveyor frame. The drive mechanism includes a motor mounted on the frame, a drive gear located at the output end of the motor, and a rack located on the pitch conveyor frame. One end of the rack is hinged to the pitch conveyor frame, and the rack meshes with the drive gear.

[0005] Preferably, the output end of the motor is provided with a dual-shaft output reducer, and the two output ends of the dual-shaft output reducer are respectively connected to drive gears. The pitch conveyor frame is provided with two parallel racks at corresponding positions, and the racks mesh with the corresponding drive gears.

[0006] Preferably, the lifting drive unit is a drive cylinder, the cylinder body of the drive cylinder is mounted on the frame, and the piston rod of the drive cylinder is hinged to the lifting frame.

[0008] Preferably, the front of the lifting frame is provided with a support crossbar, and the upper plate frame is placed on the support crossbar.

[0009] Preferably, a second unidirectional pushing component is installed in pairs on both the pitch conveyor frame and the upper plate frame.

[0010] Preferably, the second unidirectional pushing component includes a push block, a first limiting block, and a second limiting block. The push block is rotatably mounted on a pitch conveyor frame or an upper plate frame, and the push block is inclined. The first limiting block and the second limiting block are respectively mounted on the pitch conveyor frame or upper plate frame at the high end and low end of the push block, and the low end of the push block abuts against the second limiting block. The high end of the push block is provided with a pushing head facing the front end of the upper plate frame.

[0011] Preferably, the upper part of the frame is provided with two opposing sliding grooves, and multiple rollers are provided on both sides of the pitch conveyor frame, with the rollers rolling in cooperation with the corresponding sliding grooves.

[0012] Preferably, a slide rail is provided on the frame above the slide groove, and multiple L-shaped guide rods are provided on the top of the frame.

[0013] The present invention also relates to a plate feeding process, which employs the above-mentioned lifting plate feeding device, and includes the following steps:

[0014] S1. Place the pallet on the top of the frame. The pitch conveyor moves under the drive of the drive mechanism. The pitch conveyor moves the pallet pitch by pitch towards the upper plate frame. The feeding surface on the pitch conveyor is lower than the installation height of the pallet on the vibration table.

[0015] S2. When loading the plate, the lifting drive unit moves to tilt and raise the lifting frame to a position where the front end is not lower than the plate feeding surface of the plate frame.

[0016] S3. After the pitch conveyor moves forward pitch, the first pallet on the upper plate frame is sent to the vibration table along with the upper plate frame, and at the same time, the adjacent second pallet is sent to the front of the lifting frame.

During the feeding operation, the pallet can be transported to the upper plate frame at a higher position by raising the height. The height of the lifting frame can be adjusted by driving the lifting drive unit, and the pallet can be raised to the height of the upper plate. After the upper plate is placed, the height of the lifting frame can be lowered to avoid collision with the feeding frame. In addition, the drive mechanism of this invention uses gears and racks for transmission. The rack is hinged to the pitch conveyor frame, and a flexible connection is realized between the pitch conveyor frame and its drive motor. During the conveying operation, the flexible connection structure can buffer the vibration generated by the vibration table of the block forming equipment, reducing the impact of vibration on the drive motor and corresponding transmission components.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1 to 7 As shown, this embodiment provides a lifting and feeding device, including a frame 1, a pitch conveyor frame 2 slidably mounted on the frame 1, and a drive mechanism for moving the pitch conveyor frame 2. A lifting frame 3 is provided at the front of the frame 1, and the rear end of the lifting frame 3 is hinged to the frame 1. A lifting drive unit is provided at the front end of the lifting frame 3 for swinging the lifting frame 3 up and down around its rear end. An upper plate frame 201 is connected to the front end of the pitch conveyor frame 2, and the feeding surface of the upper plate frame 201 is higher than the feeding surface of the pitch conveyor frame 2. The drive mechanism includes a drive motor 101 mounted on the frame 1, a drive gear 103 located at the output end of the drive motor 101, and a rack 104 located on the pitch conveyor frame 2. One end of the rack 104 is hinged to the pitch conveyor frame 2, and the rack 104 meshes with the drive gear 103. In this embodiment, the lifting and feeding device realizes the conveying of pallets to a higher position by setting a lifting frame 3 that cooperates with the upper plate frame 201 at the front of the frame 1. At the same time, by lowering the height of the lifting frame 3, it can avoid the feeding frame.

[0030] In this embodiment, the output end of the drive motor 101 is provided with a dual-shaft output reducer 102. Drive gears 103 are respectively connected to the two output ends of the dual-shaft output reducer 102. Two parallel racks 104 are provided at corresponding positions on the pitch conveyor frame 2. The racks 104 mesh with the corresponding drive gears 103. In this embodiment, the cooperation between the racks 104 and the drive gears 103 enables a flexible connection between the pitch conveyor frame 2 and its drive motor 101. During conveying operations, this flexible connection can buffer the vibration generated by the vibrating table of the block forming equipment, reducing the impact of vibration on the drive motor 101 and corresponding transmission components, while ensuring power transmission. Preferably, the lifting drive unit is a drive cylinder 105. The cylinder body of the drive cylinder 105 is mounted on the frame 1, or it can be mounted on other fixed structures of the block forming equipment. The piston rod of the drive cylinder 105 is hinged to the lifting frame 3.

[0031] The front of the frame 1 is provided with a first one-way pushing component 109. The first one-way pushing component 109 has a first pushing block facing the front end of the lifting frame 3, and the lifting frame 3 is provided with a clearance groove 302. The first pushing block of the first one-way pushing component 109 extends to the top of the lifting frame 3 through the clearance groove 302. The pitch conveyor frame 2 and the upper plate frame 201 are each equipped with a pair of second one-way pushing components 202. The second one-way pushing component 202 includes a pushing block 2021, a first limiting block 2022, and a second limiting block 2023. The limiting block 2023 and the push block 2021 are rotatably mounted on the pitch conveyor frame 2 or the upper plate frame 201, and the push block 2021 is inclined. The first limiting block 2022 and the second limiting block 2023 are respectively mounted on the pitch conveyor frame 2 or the upper plate frame 201 at the high end and the low end of the push block 2021, and the low end of the push block 2021 abuts against the second limiting block 2023. The high end of the push block 2021 is provided with a push head 20211 facing the front end of the upper plate frame 201.

[0032] During pallet conveying, the pallet is fed onto the frame 1 and placed above the pitch conveyor 2. The drive motor 101 starts, moving the pitch conveyor 2 a certain distance towards the front end of the frame 1. The pusher block 2021 abuts against the bottom of the pallet, pushing the pallet a similar distance towards the lower end of the frame 1. Then, the drive motor 101 drives the pitch conveyor 2 to move in the opposite direction, causing the high end of the pusher block 2021 to deflect towards the low end. When the pusher block 2021 reaches the bottom of the next pallet, it abuts against the bottom of the next pallet. Thus, the pitch conveyor... The pallets can be conveyed one by one to the end of the frame 1 from the conveyor frame 2. The top two sides of the frame 1 are provided with multiple L-shaped guide rods 106. The pallets slide within the L-shaped guide rods 106. The positions of the pallets on both sides are limited by the L-shaped guide rods 106. The structure of the first one-way pushing component 109 in this embodiment is similar to that of the second one-way pushing component 202, and will not be described again here. When the lifting frame 3 is lifted by the driving cylinder 105 and tilts, the first one-way pushing component 109 will prevent the pallets on the lifting frame 3 from sliding down.

[0033] In this embodiment, the upper part of the frame 1 is provided with two opposing sliding grooves 107, and the two sides of the pitch conveyor frame 2 are respectively provided with multiple rollers 203, which roll in cooperation with the corresponding sliding grooves 107. The front part of the lifting frame 3 is provided with a support crossbar 301, and the upper plate frame 201 is placed on the support crossbar 301. The frame 1 above the sliding grooves 107 is provided with a slide rail 108. When the pitch conveyor frame 2 feeds the plate, the two sides of the plate are supported on the surface of the slide rail 108, that is, the feeding surface of the pitch conveyor frame 2 is the surface of the slide rail 108.

[0034] In this embodiment, the upper plate of the lifting and feeding device is provided with a height-adjustable lifting frame 3. The lifting frame 3 is hinged to the frame 1 and is driven by the lifting drive unit to rotate around the hinge. During the rotation, the height of the lifting frame 3 increases. When the pitch conveyor 2 pushes the pallet forward, the pallet will slide upward along the lifting frame 3 to the height of the upper plate frame 201. The first one-way pushing component 109 provided on the frame 1 abuts against the pallet when the lifting frame 3 is tilted, preventing the pallet from sliding during the conveying process. When the pitch conveyor 2 retracts and resets, the pallet on the lifting frame 3 will be placed on the upper plate frame 201. Then the lifting frame 3 resets, and the next upper plate action can push the pallet onto the vibrating table. The lifting drive unit can lower the height of the lifting frame 3 to avoid collision accidents. There is no need to wait for the feeding frame to make way and adjust, which improves production efficiency.

[0035] The operation process of the lifting and feeding device in this embodiment to transport the pallet to the vibrating table of the block forming machine includes the following steps:

[0036] S1. Place the pallet on top of the frame 1. The pitch conveyor 2 moves under the drive of the drive mechanism. The pitch conveyor 2 moves the pallet in the direction of the upper plate frame 201. The feeding surface on the pitch conveyor 2 is lower than the installation height of the pallet of the vibration table.

[0037] S2. When the plate is being lifted, the lifting drive unit moves to tilt and raise the lifting frame 3 to a position where the front end is not lower than the plate feeding surface of the upper plate frame 201.

[0038] S3. After the pitch conveyor 2 moves forward pitch, the first pallet on the upper plate frame 201 is sent to the vibration table along with the upper plate frame 201, and at the same time, the adjacent second pallet is sent to the front of the lifting frame 3.

[0039] S4. After the pitch conveyor 2 moves in the reverse pitch, the first pallet remains on the vibrating table while the upper plate frame 201 moves backward by pitch. Then the lifting drive unit is reset to the horizontal state, and the second pallet is located on the upper plate frame 201.

[0040] S5. Repeat steps S2-S4 in a loop.
