Description

Technical Field

[0001] The present invention relates to the technical field of wooden square maintenance, and specifically to a driving structure for a large-scale balancing kiln roller path. Background Art

[0002] The balancing kiln is mainly used for heat and moisture preservation maintenance of wooden squares after the reconstituted wood is pressed and formed, so as to facilitate the stable performance of the wooden square products. Since the wooden squares need to have a long time for performance stabilization in the balancing kiln, generally the balancing kiln is large in volume, has many chambers, and has a strong storage capacity. The time difference between the production rhythm of the wooden squares and the time for performance stabilization determines that the driving structure of the roller path inside the balancing kiln is relatively complex. It is necessary to independently drive between each chamber and each layer of the balancing kiln according to the production rhythm to ensure the utilization efficiency of the balancing kiln and provide sufficient time for the performance stabilization of the wooden squares. Currently, the balancing kiln is divided into several chambers, which are arranged in order from the entrance as chamber A, chamber B to chamber N. There are several rows of supporting rollers in each chamber. The supporting rollers in the same row inside the balancing kiln are at the same height. The wooden squares are transported from chamber A to chamber N through the supporting rollers. After the wooden squares are produced, they are transported into the balancing kiln at intervals. Each layer in each chamber stores one piece of wood. After the lower layer of the chamber is full, there is a sensor above each row of supporting rollers in chamber N. After the sensor recognizes the wooden square, it means that the wooden squares on this layer are full. The sensor will emit a signal to enable the staff to transport the wooden squares to be maintained to the upper layer of supporting rollers for continuous transportation. However, currently, there is a driving motor arranged on each layer of each chamber inside the balancing kiln. When needed, the motor is started to drive the roller path to transport the wooden squares forward. This type of layout has a large number of motors, low utilization rate, and a large workload during maintenance. Summary of the Invention

[0003] The present invention aims to solve the above problems, and thus provides a driving structure for a large-scale balancing kiln roller path that reduces the number of motors.

[0004] The technical solution adopted by the present invention to solve the above problems is:

[0005] A driving structure of a large-scale balanced kiln roller table comprises a plurality of rows of rollers distributed in a plurality of chambers, gears are respectively arranged at both ends of the rollers, a chain is commonly mounted on the gears on the same side of the same row of rollers in the same chamber, a first counter-shooting sensor is relatively arranged on the side wall of the innermost chamber and above each row of rollers, a first reducer is arranged at the entrance of each chamber and on the outer side of the rollers, a lifting drive mechanism extending downward to the bottom of the chamber is arranged at the top of each chamber and on the outer side of the rollers, the first reducer in the same chamber is connected to the lifting drive mechanism and moves up and down along the lifting drive mechanism, a first motor is connected to the bottom of the first reducer, second counter-shooting sensors are relatively arranged on the top and bottom surfaces at the entrance of the balanced kiln, a controller used in conjunction with the second counter-shooting sensor is arranged on the first motor, a rotating block is fixed on the outer end surface of the gear on the same side of a row of rollers near the entrance of each chamber, a key slot that passes through from top to bottom is opened on the side of the rotating block away from the gear, a square key is arranged on the output end of the first reducer, and one end of the square key is located on a vertical line formed by a plurality of key slots.

[0006] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0007] In the initial position, the square key on the first reducer is located in the keyway of the rotating block at the bottom of the warehouse. When the second pair-beam sensor recognizes that a square wood has entered, it controls the first motor in warehouse A to operate, and the first motor drives the first reducer to move. The rotating block on the first reducer is inserted into the keyway to drive the gear to move and then drive the roller to operate, so as to transport the square wood to warehouse A. After the second pair-beam sensor cannot recognize the square wood signal, the first motor in warehouse A stops working. After the second pair-beam sensor recognizes the square wood signal again, the first motors in warehouse A and warehouse B operate, and the two square woods are transported to warehouses A and B respectively. In chamber B, the above operation is repeated until the square timber is transported step by step to chamber N and the bottom layer of all chambers is filled. After the first shooting sensor recognizes that square timber has entered, it transmits a signal to the lifting drive mechanism. The lifting drive mechanism drives the first reducer to rise, and the square key of the first reducer moves to the keyway of the rotating block of the upper layer and stops. At this time, the square timber is transported in via the second layer of rollers. The above operation is repeated until each layer of all chambers is filled. The first motor structure that can be lifted and lowered by one layer reduces the number of motors by a large amount, has a high utilization rate, greatly saves costs, and reduces the amount of maintenance.

[0008] Preferably, a further technical solution of the present invention is:

[0009] The lifting drive mechanism includes a second motor fixed on the top of the chamber entrance, a second reducer is connected to the output end of the second motor, a threaded rod is connected to the output end of the second reducer, the threaded rod is placed vertically and is located on the outside of the roller, the threaded rod movably passes through the top of the chamber and the bottom end is rotatably connected to the bottom surface of the chamber, a fixed plate is arranged on the outside of the roller and between the chamber entrance and the threaded rod, a slide groove is opened on the fixed plate, a slider is clamped and slidably connected in the slide groove, a threaded sleeve and a connecting block are respectively fixed on the side of the first reducer, the threaded sleeve is sleeved on the threaded rod, the connecting block is connected to the slider, a laser displacement sensor is arranged at the bottom of the first motor and the bottom surface of the chamber relative to each other, and a controller used in conjunction with the first counter-shooting sensor and the laser displacement sensor is respectively arranged on the second motor.

[0014] The present invention will be further described below in conjunction with embodiments, the purpose of which is only to provide a better understanding of the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0015] A driving structure for a large-scale balanced kiln roller table, comprising several rows of idler rollers 1 distributed in several compartments. Gears 2 are respectively arranged at both ends of the idler rollers 1. Chains are commonly sleeved on the gears 2 on the same side of the same row of idler rollers 1 in the same compartment. On the side wall of the innermost compartment and opposite to each row of idler rollers 1 above, a first pair of photoelectric sensors are arranged. At the entrance of each compartment and outside the idler rollers, a first speed reducer 3 is arranged. At the top of each compartment and outside the idler rollers 1, a lifting driving mechanism extending downward to the bottom of the compartment is arranged. The lifting driving mechanism is connected to the first pair of photoelectric sensors. The first speed reducer 3 in the same compartment is connected to the lifting driving mechanism and moves up and down along the lifting driving mechanism. A first motor 4 is connected to the bottom of the first speed reducer 3. On the top surface and bottom surface at the entrance of the balanced kiln, second pair of photoelectric sensors 5 are arranged opposite to each other. A controller cooperating with the second pair of photoelectric sensors 5 is arranged on the first motor 4. On the outer end surface of the gear 2 on the same side of a column of idler rollers 1 near the entrance in each compartment, a rotating block 6 is fixed. A keyway 601 penetrating up and down is formed on the side surface of the rotating block 6 facing away from the gear 2. A square key 301 is arranged at the output end of the first speed reducer 3. One end of the square key 301 is located on the vertical line formed by several keyways 601.

[0016] The lifting driving mechanism includes a second motor 7 fixed at the top of the entrance of the compartment. The output end of the second motor 7 is connected to a second speed reducer 8. The output end of the second speed reducer 8 is connected to a threaded rod 9. The threaded rod 9 is vertically arranged and located outside the idler rollers 1. The threaded rod 9 movably penetrates through the top of the compartment and its bottom end is rotatably connected to the bottom surface of the compartment. The bottom end of the rod body of the threaded rod 9 and the position penetrating through the top of the compartment are both in a smooth rod structure. Outside the idler rollers 1 and between the entrance of the compartment and the threaded rod 9, a fixing plate 10 is arranged. A chute is formed on the fixing plate 10. A slider is clamped and slidably connected in the chute. A threaded sleeve and a connecting block are respectively fixed on the side surface of the first speed reducer 3. The threaded sleeve is sleeved on the threaded rod 9. The connecting block is connected to the slider. A laser displacement sensor 11 is arranged opposite to the bottom of the first motor 4 and the bottom surface of the compartment. Controllers cooperating with the first pair of photoelectric sensors and the laser displacement sensor 11 are respectively arranged on the second motor 7. When the first pair of photoelectric sensors transmit signals to the controller to drive the second motor 7 to operate, the second motor 7 drives the second speed reducer 8 and then drives the threaded rod 9 to rotate. The first speed reducer 3 slides upward along the threaded rod 9 through the threaded sleeve and the slider. Since the distance between each row of idler rollers 1 is the same, the parameter of the laser displacement sensor 11 is set to the distance between two adjacent upper and lower rows of idler rollers 1. When the first motor 4 rises to drive the square key 301 to rise from the lower keyway 601 to the upper keyway 601, the laser displacement sensor 11 transmits signals to the controller to control the second motor 7 to stop working, and then the transportation work of the wooden square in the horizontal direction is repeated.

[0017] In the initial position, the square key on the first speed reducer is located in the keyway of the rotating block at the bottommost layer of the bin. When the second pair of photoelectric sensors detects the entry of a square wooden beam, the first motor in bin A is controlled to operate. The first motor drives the first speed reducer to move. The rotating block on the first speed reducer inserts into the keyway to drive the gear to move, and then drives the idler roller to operate, transporting the square wooden beam into bin A. After the second pair of photoelectric sensors no longer detect the square wooden beam signal, the first motor in bin A stops working. When the second pair of photoelectric sensors detect the square wooden beam signal again, the first motors in bin A and bin B operate, transporting the two square wooden beams into bin A and bin B respectively. Repeat the above operations until the bottommost layer of all bins is filled with square wooden beams. After the first pair of photoelectric sensors detect the entry of a square wooden beam, they send a signal to the lifting drive mechanism. The lifting drive mechanism drives the first speed reducer to rise. The square key of the first speed reducer moves into the keyway of the rotating block on the upper layer and stops. At this time, the square wooden beam is transported in through the second-layer idler roller. Repeat the above operations until each layer of all bins is filled. By using a first motor structure that can be lifted, a large number of motors are reduced, with high utilization rate, greatly saving costs and reducing the amount of maintenance.

[0018] The above are only the preferred and feasible embodiments of the present invention, and do not limit the scope of the rights of the present invention. Any equivalent changes made by using the content of the specification and drawings of the present invention are included in the scope of the rights of the present invention.
