A plate feeding machine and plate feeding method in brick making equipment

Abstract

The present invention discloses a plate feeding machine and a plate feeding method in a brick making device. First, the reciprocating motion of the plate feeding trolley and the lifting motion of the lifting frame are coordinated so that each pallet moves forward one working position during a reciprocating process of the plate feeding trolley moving forward and backward. Then, the pushing claws on the plate feeding trolley and the heightening plates on the intermediate guide rail frame cooperate to push the pallet into a brick making machine. Before the pallet is pushed, there is no sliding friction between the plate feeding machine and the pallet, thereby reducing friction loss and improving the service life of the plate feeding machine and the pallet. Moreover, since the pallet is placed between two adjacent pushing claws of the plate feeding trolley from the beginning, the distance between the pallet and the corresponding pushing claw is fixed during the process of the plate feeding trolley moving forward or backward one working position, the pushing claw is always located on the pushing side of the pallet, and the pushing claw will not collide with the pallet, so that the plates can be fed continuously and smoothly with high efficiency.

Description

Technical Field

[0001] The present invention relates to the technical field of brick making equipment, in particular to a board feeding machine and a board feeding method in brick making equipment. Background Art

[0002] Brick making equipment is a mechanical equipment for producing bricks, in which a plate feeder is arranged at the front end of a block brick forming machine, and is used to feed an empty pallet into the brick forming machine of the block brick forming machine, and the pallet cooperates with the brick making mold to receive the material and form the block brick; when feeding the plate, each pallet is placed on the support key strip of the frame in sequence, and the plate feeder is located below the pallet, and the plate feeder includes a driving cylinder and a plate feeding trolley, and the piston rod of the driving cylinder extends out to push the plate feeding trolley to move, and each shifting block on the plate feeding trolley extends upward to push each pallet to slide on the support key strip of the frame until the front pallet is sent to the working table of the forming mechanism, and then the plate feeding trolley retreats and waits for the next push; because the bottom of the pallet is always rubbed against the support key strip of the bracket during the plate feeding process, it is easy to cause wear to the pallet and the support key strip, thereby reducing the service life of the pallet and the support key strip; and Moreover, each pallet is placed at a different position on the support key bar, so that there is a certain distance between each push claw and the corresponding pallet, and the distances are different; in the same plate pushing process, the pallet close to the push claw is pushed first, and the pallet far from the push claw is pushed later, and the push claws cannot push the corresponding pallet synchronously; and due to the different distances between each push claw and the corresponding pallet to be pushed, the plate delivery trolley pushes the plate away from the plate delivery machine and enters the brick making machine each time it moves forward, and then the plate delivery trolley retreats a different distance each time, and the retreat distance of the plate delivery trolley cannot be accurately controlled each time; therefore, when the plate delivery trolley retreats for the next plate pushing, some push claws may not be able to be located on the side of the plate pushing, resulting in the inability to push the plate, or the push claws may collide with the pallet, causing the pallet to shift and tilt, making it difficult to push the plate, resulting in an unsmooth plate delivery process and low plate delivery efficiency.

[0003] In view of this, the applicant has made in-depth considerations and actively researched, improved and tried to develop and design the present invention in order to solve the many deficiencies and inconveniences caused by the imperfections of the above-mentioned plate feeding machine and plate feeding method.

When the plate delivery trolley starts to push the plate, although there will be friction between the pallet and the heightened plate, compared with the friction damage caused by the entire existing sliding movement process of pushing the plate, the sliding distance of the pallet is reduced, thereby reducing the friction damage to the pallet, and the heightened plate can be replaced separately, reducing maintenance costs. Moreover, The pallet is placed between two adjacent push claws of the pallet delivery trolley from the very beginning. When the pallet delivery trolley moves forward one station, the pallet also moves forward one station synchronously. The distance between the pallet and the corresponding push claw is fixed, and this distance will not change because the pallet delivery trolley moves forward one station. When the pallet delivery trolley retreats one station, the push claw is always on the side where the pallet is pushed, and the push claw will not collide with the pallet. Therefore, when the pallet delivery trolley retreats, there is no need to consider the distance between the push claw and the pallet, and the retreat distance of the pallet delivery trolley can be accurately controlled, making the pallet delivery process smoother and the pallet delivery efficiency higher.

The plate feeder in the brick making equipment according to claim 1, characterized in that: The two lifting frames are respectively provided with a plurality of vertical parts extending downward, and the bottom ends of the vertical parts are provided with a first pivot seat; the frame is provided with a second pivot seat corresponding to each first pivot seat, and the first pivot seat and the second pivot seat correspondingly arranged above and below are respectively rotatably pivoted at two ends of a linkage rod; the second driving mechanism has a piston seat locked on the frame and a piston rod locked on the lifting frame; the second driving mechanism extends the piston rod to push the lifting frame to rise and then lift the pallet away from the plate delivery trolley or the intermediate guide rail frame, and the second driving mechanism retracts the piston rod to pull the lifting frame down and then place the pallet on the plate delivery trolley or the intermediate guide rail frame.

8. A method for delivering boards in a brick making device, characterized in that: The board feeding machine as described in any one of claims 1 to 7 is used to feed the board, and the following steps are included: Step S1, placing a pallet on the first station at the starting end of the pallet delivery trolley; Step S2, the first driving mechanism drives the plate-feeding trolley to move forward one station, and drives the pallet on the first station to move forward one station; Step S3, the second driving mechanism drives the lifting frame to rise and lift the pallet on the first station to be suspended above the pallet delivery trolley; Step S4, the first driving mechanism drives the plate-feeding trolley to retreat one station, and the second driving mechanism drives the lifting frame to descend to place the plate on the second station; Step S5, repeating steps S1 to S4, during the process of the pallet delivery trolley moving forward and backward, each pallet moves forward one station; Step S6, when the pallet moves forward to the penultimate station of the pallet delivery trolley, the pallet delivery trolley advances one station in the next round, and the pallet on the penultimate station of the pallet delivery trolley is pushed from the pallet delivery trolley to the heightening plate by the penultimate push claw; Step S7, the second driving mechanism drives the lifting frame to rise and place the pallet on the pallet delivery trolley or the heightening plate, the first driving mechanism drives the pallet delivery trolley to retreat one station, and the second driving mechanism drives the lifting frame to descend and place the pallet on the pallet delivery trolley or the heightening plate; Step S8, when the first driving mechanism drives the plate-feeding trolley to move forward one station, the last pushing claw is used to push the support plate on the heightening plate by one station and move it to the brick-making machine; Step S9, repeating steps S5 and S8, and continuously feeding the boards.
