At the joints between conveyors, the heights of the conveyors need to be flush with each other to avoid the plate getting stuck between the two conveyors due to the height difference, or the plate that was originally straightened tilting due to the height difference. The tilted plate cannot enter the machine normally, and manual adjustment is required, which seriously affects the processing efficiency. Utility Model Content

[0003] In order to improve the efficiency of connecting and transferring plates between conveyors, the present application provides a transfer and lifting device for plates.

[0006] By adopting the above technical solution, when in use, the power mechanism is started, driving the lifting mechanism connected thereto to lift one side of the lifting frame, and the other lifting mechanism synchronously lifts the other side of the lifting frame through the transmission of the transmission mechanism, thereby making the lifting frame rise and fall. The movement of the lifting frame drives the horizontal conveying mechanism to rise and fall, so that the lifting and falling can be adjusted according to the height of the conveyors at the front and rear ends of the device, and the horizontal conveying mechanism can drive the plate to be transported in the horizontal direction, thereby realizing the continuous transportation of the plate between two conveyors at different heights, thereby facilitating the improvement of the efficiency of the connection and transfer of the plate between the conveyors.

[0008] By adopting the above technical solution, when the winding shaft rotates along the set direction, one end of the lifting belt is gradually wound around the winding shaft, and the other end of the lifting belt drives the lifting frame to gradually rise. The lifting mechanism of the present application is mainly located on both sides of the lifting frame. Compared with setting a scissors-type lifting mechanism at the bottom of the lifting frame to achieve lifting, the lower limit position of the lifting frame in the present application can be set lower, which is beneficial to improving the scope of use of the device.

[0009] Optionally, the transmission mechanism includes a transmission shaft and first bevel gears arranged at both ends of the transmission shaft, the transmission shaft is rotatably connected to two fixing frames, and second bevel gears are arranged on the two winding shafts, and the first bevel gear is meshed with the corresponding second bevel gear on the same side.

The present application sets up a transmission mechanism, so that both lifting mechanisms do not need to be connected to a power mechanism, reducing the number of power sources, which is conducive to improving the energy efficiency of the device.

[0011] Optionally, the power mechanism includes a driving motor and a reducer, the input end of the reducer is connected to the output end of the driving motor, and the output end of the reducer is coaxially fixed to one of the winding shafts.

[0013] Optionally, a base frame is provided at the bottom end of the lifting frame, the base frame is arranged corresponding to the lifting belt, a bottom wheel is provided on the base frame, and the lifting belt is connected to the lifting frame after passing around the corresponding fixed pulley and the bottom wheel in sequence.

The bottom wheel can avoid the lifting belt from contacting the lifting frame when leading it out from the bottom of the lifting frame, causing sliding wear, which is beneficial to extending the service life of the lifting belt.

[0015] Optionally, contact rollers are provided on both sides of the lifting frame, and wheel surfaces of the contact rollers abut against inner sides of adjacent fixing frames.

[0016] By adopting the above technical solution, the sliding friction between the lifting frame and the fixed frame is converted into rolling friction through the contact roller, which is beneficial to reducing the wear of the lifting frame and the fixed frame. Compared with installing a linear slide rail between the two, installing the contact roller is more economical and convenient.

[0019] Optionally, the horizontal conveying mechanism includes multiple conveyor belts, which are fixed to the lifting frame through a mounting frame, the conveying direction of the conveyor belts is the same as the length direction of the lifting frame, and the top belt surfaces of the multiple conveyor belts are flush with each other.

[0021] Optionally, blocks are provided on both sides of the lifting frame, and a lower limit piece and an upper limit piece corresponding to the blocks are provided on one side of the fixed frame close to the lifting frame, and the block is located between the lower limit piece and the upper limit piece.

[0022] By adopting the above technical solution, the upper limit height of the stopper is determined by the upper limit member, and the lower limit height of the stopper is determined by the lower limit member, so that the upper and lower limit heights of the lifting frame can be set according to actual needs. In addition, by setting the upper limit member and the lower limit member, it is ensured that the lifting frame is stably lifted and lowered along the fixed frame, reducing the possibility of the lifting frame being detached from the fixed frame.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the setting of the lifting mechanism, transmission mechanism, power mechanism and horizontal conveying mechanism, when in use, the power mechanism is started, driving the lifting mechanism connected thereto to lift one side of the lifting frame, and the other lifting mechanism synchronously lifts the other side of the lifting frame through the transmission of the transmission mechanism, thereby making the lifting frame rise and fall.

The lifting mechanism of the present application is mainly located on both sides of the lifting frame. Compared with setting a scissors-type lifting mechanism at the bottom of the lifting frame to achieve lifting, the lower limit position of the lifting frame in the present application can be set lower, which is beneficial to improving the scope of use of the device.

[0026] 3. By setting the limiting roller, the lifting frame can be limited in the length direction to avoid horizontal deviation when the lifting frame is raised or lowered, thereby further improving the stability of the device when it is raised or lowered. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 , further details of this application are given.

[0033] Example:

[0034] The present application embodiment discloses a transport and lifting device for plates. Figure 1A transport and lifting device for plates comprises a lifting frame 1 and fixed frames 2 arranged on both sides of the lifting frame 1, wherein the lifting frame 1 is slidably arranged between the two fixed frames 2. A horizontal conveying mechanism 3 is arranged on the top of the lifting frame 1, and a lifting mechanism 4 is arranged on the fixed frame 2. The lifting mechanism 4 is connected to an adjacent side of the lifting frame 1, and the two lifting mechanisms 4 are connected by a transmission mechanism 5, and one of the lifting mechanisms 4 is connected to a power mechanism 6.

[0035] When in use, the power mechanism 6 is started, driving the lifting mechanism 4 connected thereto to lift one side of the lifting frame 1, and the other lifting mechanism 4 synchronously lifts the other side of the lifting frame 1 through the transmission of the transmission mechanism 5, thereby lifting the lifting frame 1. The movement of the lifting frame 1 drives the horizontal conveying mechanism 3 to move up and down, so that the lifting and lowering can be adjusted according to the height of the conveyors at the front and rear ends of the device, and the horizontal conveying mechanism 3 can drive the plate to be transported in the horizontal direction, thereby realizing the continuous transportation of the plate between two conveyors at different heights, thereby facilitating the improvement of the efficiency of the connection and transportation of the plate between the conveyors.

[0036] Reference Figure 1 The lifting mechanism 4 includes a winding shaft 41 and a plurality of lifting belts 42. The winding shaft 41 is rotatably arranged on the corresponding fixed frame 2 and arranged along the length direction of the corresponding fixed frame 2. The fixed frame 2 is rotatably connected with a fixed pulley 21 arranged corresponding to the lifting belt 42. The installation height of the fixed pulley 21 is higher than the installation height of the winding shaft 41. One end of the lifting belt 42 is fixed to the side wall of the winding shaft 41, and the other end is connected to the lifting frame 1 after passing through the fixed pulley 21. In this embodiment, each lifting mechanism 4 is provided with two lifting belts 42. When the winding shaft 41 rotates along the set direction, one end of the lifting belt 42 is driven to be gradually wound on the winding shaft 41, and the other end of the lifting belt 42 drives the lifting frame 1 to gradually rise. The lifting mechanism 4 of the present application is mainly located on both sides of the lifting frame 1. Compared with setting a scissor-type lifting mechanism at the bottom of the lifting frame 1 to achieve lifting, the lower limit position of the lifting frame 1 in the present application can be set lower, which is conducive to improving the use range of the device.

[0037] Reference Figure 1The transmission mechanism 5 includes a transmission shaft 51 and a first bevel gear 52 coaxially fixed at both ends of the transmission shaft 51. The transmission shaft 51 is rotatably connected to the two fixing frames 2. The two winding shafts 41 are coaxially fixed with second bevel gears 411, and the first bevel gear 52 is meshed with the corresponding second bevel gear 411 on the same side. When one of the winding shafts 41 rotates, it drives the corresponding second bevel gear 411 to rotate, and the rotation of the second bevel gear 411 drives the corresponding first bevel gear 52 to rotate, thereby driving the transmission shaft to rotate; the rotation of the transmission shaft 51 drives the other winding shaft 41 to rotate synchronously through the transmission of another group of first bevel gears 52 and second bevel gears 411. The present application, through the setting of the transmission mechanism 5, does not need the two lifting mechanisms 4 to be connected to the power mechanism 6, reduces the number of power sources, and is conducive to improving the energy efficiency of the device.

[0038] Reference Figure 2-3 The power mechanism 6 includes a driving motor 61 and a reducer 62. The input end of the reducer 62 is connected to the output end of the driving motor 61, and the output end of the reducer 62 is coaxially fixed to one of the winding shafts 41. The driving motor 61 outputs torque, which is decelerated and amplified by the reducer 62, and then the amplified torque is transmitted to the winding shaft 41 connected thereto, which ensures the stability of the lifting adjustment on the one hand, and the load capacity of the lifting frame 1 on the other hand.

[0039] Reference Figure 2 The bottom end of the lifting frame 1 is fixedly connected to the base frame 11, and the base frame 11 is correspondingly arranged with the lifting belt 42. The base wheel 12 is rotatably mounted on the base frame 11, and the lifting belt 42 passes through the corresponding fixed pulley 21 and the base wheel 12 in sequence and is connected to the bottom wall of the lifting frame 1. In this embodiment, the overall outline of the base frame 11 is triangular and the two bottom corner ends of the base frame 11 are both provided with base wheels 12. In this way, one end of the lifting belt 42 in the present application is fixed to the bottom of the lifting frame 1, and the other end passes through the base wheel 12 and then passes through the fixed pulley 21, which is conducive to further improving the stability of the lifting frame 1. The base wheel 12 can avoid the lifting belt 42 from contacting with the lifting frame 1 when the lifting belt 42 is led out from the bottom of the lifting frame 1, causing sliding wear, which is conducive to extending the service life of the lifting belt 42.

[0040] Reference Figure 3-4 , connecting frames 13 are fixed on both sides of the lifting frame 1, and contact rollers 14 are rotatably connected to the connecting frames 13, and the wheel surface of the contact rollers 14 abuts against the inner side of the adjacent fixed frame 2. The contact rollers 14 convert the sliding friction between the lifting frame 1 and the fixed frame 2 into rolling friction, which is beneficial to reducing the wear of the lifting frame 1 and the fixed frame 2. Compared with installing a linear slide rail between the two, installing the contact rollers 14 is more economical and convenient.

[0041] Reference Figure 3-4In order to prevent the lifting frame 1 from deflecting in the horizontal direction when it is lifted, limit rollers 22 are provided at both ends of the fixed frame 2. The wheel surface of the limit rollers 22 abuts against the adjacent end surface of the corresponding fixed frame 2. The limit rollers 22 are rotatably provided on the connecting frame 13. The limit rollers 22 can limit the lifting frame 1 in the length direction, thereby further improving the stability of the device when it is lifted.

[0042] Reference Figure 2 , stoppers 15 are also installed on both sides of the lifting frame 1, and a lower stopper 23 and an upper stopper 24 corresponding to the stopper 15 are fixed on one side of the fixed frame 2 close to the lifting frame 1, and the stopper 15 is located between the lower stopper 23 and the upper stopper 24. In this embodiment, the lower stopper 23 and the upper stopper 24 are both square tube components. The upper limit height of the stopper 15 is determined by the upper limit height 23, and the lower limit height of the stopper 15 is determined by the lower limit height 24, so that the upper and lower limit heights of the lifting frame 1 can be set according to actual needs. In addition, the upper limit height 24 and the lower limit height 23 are set to ensure that the lifting frame 1 is stably lifted and lowered along the fixed frame 2, and the possibility of the lifting frame 1 and the fixed frame 2 being separated is reduced.

[0043] Reference Figure 1 The horizontal conveying mechanism 3 includes a plurality of conveyor belts 31, which are fixed to the top of the lifting frame 1 through a mounting frame 32. The conveying direction of the conveyor belts 31 is the same as the length direction of the lifting frame 1, and the top belt surfaces of the plurality of conveyor belts 31 are flush with each other. After placing the plate on the conveyor belt 31, the conveyor belt 31 is started, and the plate can be transported in the horizontal direction, thereby achieving the purpose of supporting and transferring the plate.
