Description

Technical Field

[0001] The invention belongs to the technical field of curing kiln transfer, and in particular relates to a fully automatic circulation system for brickwork curing. Background Art

[0002] Unfired bricks are pressed and formed using brick making equipment. Specifically, the mixed blank is injected into the lower mold, and then the upper mold is lowered to close the mold and a certain vibration effect is applied. The brick blank is pressed and formed. After demolding, the brick blank needs to be transferred to the curing kiln for a certain process time. During the curing process, the brick blank gradually builds up structural strength and forms the final unfired brick product.

[0003] As the production scale of unfired bricks becomes larger and larger, higher and higher requirements are put forward for the curing kiln's capacity to accommodate brick blanks. Although the existing curing kiln is large, some bricks will be divided into two batches and enter the curing kiln at different times. The bricks that enter the curing kiln first will be transported away by the mother-and-child transfer vehicle at the exit when the time comes, while the bricks that enter the curing kiln later need to be moved so that new bricks can enter the curing kiln. The moving position is usually carried out by the mother-and-child transfer vehicle at the exit. Therefore, if the curing time of another brick is up, it is necessary to wait for the mother-and-child transfer vehicle to complete the movement before the bricks can be discharged, resulting in low efficiency.

The above-mentioned actions are repeated to move the curing frame 11 that enters the curing kiln 1 late. Specifically, the moving assembly 9 includes a rotating screw 901, a moving seat 902 and a transmission motor 903. The rotating screw 901 is rotated and placed in the installation slot 8.

A plurality of mother-and-child transfer vehicles 2 are divided into two groups with the transition storage area 101 as the central axis to form a first-area mother-and-child transfer vehicle 2 and a second-area mother-and-child transfer vehicle 2. During maintenance, the curing rack 11 filled with bricks is transferred to the first curing area 102 by the first-area mother-and-child transfer vehicle 2 at the input of the curing kiln 1. The first curing area 102 is first filled, and then the curing rack 11 is placed on the transition storage area 101 by the first-area mother-and-child transfer vehicle 2. The curing rack 11 is then transferred to the second curing area 103 for storage by the second-area mother-and-child transfer vehicle 2, thereby increasing the storage scale. The first-area mother-and-child transfer vehicle 2 and the second-area mother-and-child transfer vehicle 2 at the output of the curing kiln 1 can successively take out the bricks to be cured, and are independent of the first-area mother-and-child transfer vehicle 2 and the second-area mother-and-child transfer vehicle 2 at the input of the curing kiln 1 and do not affect each other, thereby accelerating the transfer efficiency.

[0021] Furthermore, there are four mother-child transfer vehicles 2, which include a mother vehicle 201 and a child vehicle 202. The child vehicle 202 is moved and placed on the mother vehicle 201. The child vehicle 202 includes a driving vehicle 203, a lifting assembly 204, and a receiving frame 205. The lifting assembly 204 is installed on the driving vehicle 203, and the receiving frame 205 is installed on the driving end of the lifting assembly 204. The driving vehicle 203 is moved out to drive the receiving frame 205 to be located below the curing frame 11, and then the lifting assembly 204 drives the receiving frame 205 to lift the curing frame 11, and the driving vehicle 203 is retracted and placed on the mother vehicle 201. At the same time, the lifting assembly 204 drives the receiving frame 205 to descend and reset, and finally the mother vehicle 201 is used for transfer.

[0022] Furthermore, the curing frame 11 is a double-layer curing frame 11, and a resisting assembly for resisting the top of the double-layer curing frame 11 is installed on the top of the supporting frame 205, and the resisting assembly includes a mounting frame 206, a servo electric cylinder 207 and a clamping frame 208. The mounting frame 206 is mounted on the top of the supporting frame 205, the servo electric cylinder 207 is rotatably mounted in the mounting frame 206, and the clamping frame 208 is movably mounted below the mounting frame 206, and one side of the clamping frame 208 is rotatably connected to the driving end of the servo electric cylinder 207.

When the child car 202 receives the curing frame 11, the two push correction assemblies 209 are driven at the same time, and the pushing cylinder 2011 drives the correction plate 2012 to move toward the child car 202, so that the correction plate 2012 pushes the curing frame 11 to the correct position to prevent the curing frame 11 from shifting to the left or right, so that when the curing frame 11 is placed later, the storage position of the curing frame 11 will also be incorrect, thereby affecting the subsequent placement of the curing frame 11. Specifically, the driving vehicle 203 is equipped with a push cylinder 2013, and the output end of the push cylinder 2013 is equipped with a push piece 2014, and the push piece 2014 is rotatably connected to the driving vehicle 203. After the curing frame 11 is aligned, the push cylinder 2013 pushes the push piece 2014, so that the push piece 2014 rotates around the connection end with the driving vehicle 203, thereby driving the elastic pad to push against the curing frame 11, and the curing frame 11 is clamped and fixed.

[0024] Furthermore, the curing kiln 1 is provided with positioning calibrators at both symmetrical ends of the guide rail 4, and the mother car 201 is provided with a positioner that cooperates with the positioning calibrator.
