Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, and in particular to a novel combined falling plate crushing mechanism and an operating method thereof. Background Art

[0002] In the flat glass production line, when the front defect detector detects unqualified glass, the glass ribbon is cut into glass plates of different lengths and widths through the optimized cutting system. When the defective glass plate passes through the plate drop area, the plate drop roller in the corresponding area swings downward, and the unqualified plate is transported down to the crusher for crushing. At the same time, the qualified glass plate continues to be transported to the next process by the plate drop roller in the corresponding area.

[0003] Today's flat glass production lines have been upgraded to intelligent ones, and most of them are equipped with optimized cutting systems. After optimization, there are many specifications of unqualified red strips, ranging from narrow strips with very small lengths to whole plates with very large lengths. The range of variation is particularly large. Since the length of the swing roller in the drop mechanism is closely related to the length of the glass plate that needs to be dropped, in order to make the glass plate fall smoothly, the length of the swing roller is generally required to be not less than 2 / 3 of the length of the glass plate. In order to meet the drop demand of long plates, the length of the swing roller must be very long, and at the same time, the drop demand of extra-short plates must be taken into account. However, the incoming cycle of short plates is particularly small. If the swing roller is too long, the drop cycle will be increased. When the swing roller is not lifted, the next qualified plate glass has arrived at the position of the swing roller, resulting in it being unable to pass smoothly. The existing drop mechanisms on the market are either small drop devices for small and medium-sized plates, or integral drop devices for large plates. The specifications of the dropped glass plates are single, and they all have certain limitations and cannot meet these changes at the same time. Summary of the Invention

[0004] In view of the above problems existing in the existing dropping mechanism, the present invention aims to provide a new combined falling plate crushing mechanism and an operating method with wide applicability and stable dropping.

[0009] a first driving assembly, the first driving assembly being used to drive the plurality of conveying rollers to rotate synchronously;

[0010] The second drive assembly is connected to the two lower swing frames in a transmission manner and is used to drive the lower swing frames to swing downward on one side away from the mounting frame, so that the large defective glass plates on the conveying roller and the key blanking device fall onto the inclined receiving roller.

[0011] As a further improvement and optimization of this solution, the key blanking device includes:

[0012] A piano key frame, the piano key frame being fixed between the two lower swing frames;

[0013] a plurality of conveying keys, one end of each of the conveying keys being rotatably mounted on the key frame, and the other ends of each of the conveying keys being respectively provided with a plurality of first driving members, each of the first driving members being used to drive the free ends of the plurality of conveying keys to swing downward to drop small defective glass sheets, and a plurality of conveying rollers being rotatably mounted on the conveying keys for conveying the glass sheets;

[0014] The third driving assembly is used to drive the plurality of conveying rollers to rotate synchronously.

[0015] As a further improvement and optimization of this solution, a number of key drop plate receiving rollers are provided below the several conveying rollers near the unloading end of the conveying keys. The several key drop plate receiving rollers are rotatably arranged between the two lower swing frames and are arranged at equal intervals along the slope direction of the inclined receiving roller conveyor. A fourth drive assembly is installed on one of the lower swing frames, and the fourth drive assembly is used to drive the several key drop plate receiving rollers to rotate so as to transfer the small defective glass plates dropped from the conveying keys to the inclined receiving roller conveyor.

[0016] As a further improvement and optimization of this solution, the second drive component includes:

[0017] A frame, wherein a drive shaft is rotatably provided on the frame, the axial direction of the drive shaft is parallel to the axial direction of the conveying roller, and a crank connecting rod mechanism is provided between the conveying roller and the lower swing frame;

[0018] a driving motor, the driving motor being mounted on the frame and in driving connection with the driving shaft, for driving the driving shaft to rotate and driving the lower swing frame to swing through the crank-connecting rod mechanism;

[0019] Two cylinders are installed on the frame, and the output ends of the two cylinders are respectively connected to the two lower swing frames for assisting the lower swing frames to swing.

[0020] As a further improvement and optimization of this solution, the first drive component includes:

[0021] A roller motor, the roller motor being mounted on one of the lower swing frames;

[0022] A transmission component is provided between the driving motor and the plurality of conveying rollers, and the driving motor drives the plurality of conveying rollers to rotate through the transmission component.

[0023] As a further improvement and optimization of this solution, the first driving member is an electric cylinder.

[0024] As a further improvement and optimization of this solution, the outer coaxial sleeve of the conveying roller is provided with a rubber ring.

[0025] An operating method, characterized in that it includes any one of the above-mentioned crushing mechanisms, and the method is:

[0026] When a large glass plate with defects passes through the combined blanking structure, the driving motor drives the driving shaft to rotate, and drives the lower swing frame to swing downward through the drive of the crank connecting rod mechanism and the cylinder. At the same time, the plurality of conveying keys of the key blanking device do not swing, but swing downward synchronously with the lower swing frame. The large glass plate with defects enters the slope receiving roller conveyor under the conveyance of the plurality of conveying rollers and the plurality of conveying rollers on the conveying keys, and is conveyed by the slope receiving roller conveyor to the crusher for crushing.

[0027] When a glass plate with small defects passes through the combined blanking structure, when passing through the key blanking device, several conveying keys corresponding to the position of the glass plate below are respectively swung down under the action of several electric cylinders, and are guided by several conveying rollers to be transported to several key drop plate receiving rollers, and are transported to the slope receiving roller conveyor under the transmission of several key drop plate receiving rollers, and finally are crushed by the crusher.

[0028] Compared with the prior art, the above technical solution has the following positive effects:

The present invention has wide applicability and low production investment cost for the equipment.

[0030] (2) In the present invention, when a large glass plate is blanked, the piano key blanking device is arranged on the two lower swing frames in the lower swing blanking device, resulting in a relatively large overall gravity of the lower swing frame. A separate cylinder drive cannot meet the requirements for the swing of the lower swing frame and the requirements for the swing rhythm. Therefore, in order to solve this problem, a crank-connecting rod mechanism is designed, and a driving motor is used to drive the driving shaft to rotate. The driving shaft acts on the lower swing frame through the crank-connecting rod mechanism. At the same time, the cylinder is used again to assist the lower swing frame so that the lower swing frame can swing, achieving the effect of fast swinging and controllable rhythm.

[0031] (3) The keyboard blanking device in this embodiment can realize blanking operations on small blanking plates of different specifications according to the feeding of the swing-transmitting keyboard, thereby further improving the applicability.

[0032] (4) In the present invention, the transmission keys are swung by electric cylinders, which improves the swing accuracy and swing speed of the transmission keys and improves the stability of the transmission blanking. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In the actual working process:

[0047] When a large glass plate 4 with defects passes through the combined blanking structure, the driving motor 1155 drives the driving shaft 1153 to rotate, and drives the lower swing frame 112 to swing downward through the drive of the crank connecting rod mechanism 1152 and the cylinder 1151. At the same time, the multiple conveying keys 122 of the key blanking device 12 do not swing, but swing downward synchronously with the lower swing frame 112.
