Description

Technical Field

[0001] The invention relates to the technical field of glass production equipment, in particular to a cold end double-layer roller conveyor. Background Art

[0002] Glass is a non-crystalline solid that can maintain a certain shape. It is a material obtained by gradually cooling the glass paste melt and increasing its density. In today's society, glass has been popularized in people's lives and glass products can be seen everywhere. At present, the cold end technology of the glass production line is becoming more and more mature, and the performance requirements for the cold end roller are gradually increasing. The cold end roller is a device used to transport glass for subsequent production operations.

[0003] However, the surface of the cold-end roller usually contains both intact glass and glass broken by external forces. The broken glass is not only easy to damage the conveying roller, but also has a certain impact on subsequent production operations. The existing cold-end roller cannot effectively collect the damaged and broken glass, and then facilitate centralized processing. When the cold-end roller reaches a certain position in the process of transporting glass, the glass needs to be stopped and positioned at a set position so that the stacker can grab the glass from the roller. At present, the blocking mechanism designed for this stacking area in China mostly uses a cylinder to directly push a block rotating around a point to extend out of the upper surface of the roller to block the glass. The equipment occupies a large space, the mechanism is easily damaged, maintenance is difficult, and the cost is high, which affects the normal transportation of the subsequent glass. Therefore, it is necessary to provide a cold-end double-layer roller to solve the above problems. Summary of the invention

By providing the No. 2 conveying roller, the transportation volume of glass is effectively increased and the conveying efficiency of glass is improved. By providing the rubber sleeve, the glass is effectively supported to facilitate the operation of the machine and effectively reduce the contact area with the glass, so that the damaged glass falls on the No. 2 conveyor belt due to lack of support.

[0021] 2.

The movement of the movable frame effectively drives the movable rod to swing under the limiting action of the pin shaft, and the swing of the movable rod and the push-pull action of the connecting rod effectively drive the baffle to slide up and down under the limiting action of the limiting slider, thereby effectively blocking the glass and facilitating the next step of grabbing the glass.

[0023] 4. This cold-end double-layer roller conveyor, when the glass moves to the end on the No. 1 conveyor roller and the No. 2 conveyor roller, it effectively contacts and squeezes the elastic block. The elastic block is squeezed and moves inward, thereby effectively driving the No. 1 arc spring piece and the No. 2 arc spring piece to bend inward. At this time, the spring expands, thereby effectively buffering the force and preventing the glass from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] According to the attached Figure 1 , 3As shown in Figure 5, a transmission mechanism 7 is movably provided on the outer surface of the No. 2 support plate 101. The transmission mechanism 7 includes a rotating rod 701, a bearing member 704, a No. 1 bevel gear 702 and a No. 2 bevel gear 703.

[0037] According to the attached Figure 2-6 As shown, a blocking mechanism 8 is fixedly arranged at the end between the No. 1 support plate 1 and the No. 2 support plate 101, and the blocking mechanism 8 includes a motor, a mounting plate 801, a rotating disk 802 and a movable frame 804, the rotating disk 802 is movably connected to the mounting plate 801, a limiting shaft 803 is fixedly arranged on the outer surface edge of the rotating disk 802, an arc groove 805 is provided on the movable frame 804, and the limiting shaft 803 is slidably connected to the arc groove 805, the blocking mechanism 8 also includes a movable rod 806, a connecting rod 807, a baffle 808 and a limiting slider 809, the lower end of the movable rod 806 is movably connected to the mounting plate 801 through a pin shaft, the movable rod 806 is movably connected to the movable frame 804, and the upper end of the movable rod 806 is connected to the connecting rod The rod 807 is movably connected, and the upper end of the connecting rod 807 is movably connected to the baffle 808 through a pin shaft. The motor effectively drives the rotating disk 802 to rotate, and the rotation of the rotating disk 802 drives the limiting shaft 803 to rotate synchronously. Since the limiting shaft 803 is slidingly connected with the arc groove 805, the inner wall of the arc groove 805 is effectively squeezed during the rotation of the limiting shaft 803, driving the movable frame 804 to move. The movement of the movable frame 804 effectively drives the movable rod 806 to swing under the limiting action of the pin shaft, and the baffle 808 is effectively driven to slide up and down under the limiting action of the limiting slider 809 through the swing of the movable rod 806 and the push-pull action of the connecting rod 807, thereby effectively blocking the glass and facilitating the next step of grabbing the glass.

[0038] According to the attached Figure 4 and 7As shown, an elastic shock-absorbing component 9 is movably provided on the surface of one end of the baffle 808 away from the connecting rod 807, and the elastic shock-absorbing component 9 includes a first arc-shaped spring piece 903 and a second arc-shaped spring piece 904. The lower ends of the first arc-shaped spring piece 903 and the second arc-shaped spring piece 904 are fixedly connected to the baffle 808, and a spring 905 is fixedly provided between the first arc-shaped spring piece 903 and the second arc-shaped spring piece 904. An elastic block 901 is fixedly provided on the upper ends of the first arc-shaped spring piece 903 and the second arc-shaped spring piece 904, and an elastic groove 902 is provided on the elastic block 901. When the glass moves to the end on the first conveying roller 2 and the second conveying roller 201, it effectively contacts the elastic block 901 and squeezes the elastic block 901.

At this time, the spring 905 expands, thereby effectively buffering the force and preventing the glass from being damaged.

[0039] Working principle: when the cold end double-layer roller is working, the driving motor 501 is used to effectively drive the driving wheel 502 to rotate, and the driving wheel 502 is rotated to effectively drive the two driven wheels 503 to rotate under the transmission action of the synchronous belt, and the two driven wheels 503 are effectively driven to rotate synchronously by the first driving gear 504 and the second driving gear 505, and the first driving gear 504 and the second driving gear 505 are effectively driven to rotate by the two driven gears 203, and the first conveying roller 2 and the second conveying roller 201 are effectively driven to rotate synchronously to complete the effective conveying of the glass, and the second conveying roller 201 is provided to effectively increase the transportation volume of the glass and improve the transportation efficiency of the glass, and the rubber sleeve 202 is provided to effectively support the glass, facilitate the operation of the machine, and effectively reduce the contact area with the glass, so that the damaged glass falls on the second conveyor belt 301 due to lack of support, and the broken glass is effectively collected by the second collecting frame 401, which is convenient for further centralized processing and avoids affecting the subsequent production operations.

[0040] Furthermore, by rotating the No. 1 conveyor roller 2 and the No. 2 conveyor roller 201, the No. 1 bevel gear 702 meshing with the two No. 2 bevel gears 703 is effectively driven to rotate, and under the transmission action of the rotating rod 701, the remaining No. 1 bevel gears 702 are effectively driven to rotate synchronously, and then the No. 1 bevel gear 702 effectively drives the No. 2 bevel gear 703 at the end of the No. 1 conveyor belt 3 and the No. 2 conveyor belt 301 to rotate, thereby realizing the effective operation of the No. 1 conveyor belt 3 and the No. 2 conveyor belt 301, and effectively driving the rotating disk 802 to rotate through the operation of the motor. The rotating disk 802 rotates to drive the limiting shaft 803 to rotate synchronously. Since the limiting shaft 803 is slidably connected with the arc groove 805, the limiting shaft 803 effectively squeezes the inner wall of the arc groove 805 during the rotation process, driving the movable frame 804 to move. The movable frame 804 moves to effectively drive the movable rod 806 to swing under the limiting action of the pin shaft. The movable rod 806 swings and the baffle 808 is effectively driven to slide up and down under the limiting action of the limiting slider 809 under the push-pull action of the connecting rod 807, thereby effectively blocking the glass and facilitating the next step of grabbing the glass.

[0041] At the same time, when the glass moves to the end on the No. 1 conveyor roller 2 and the No. 2 conveyor roller 201, it effectively contacts and squeezes the elastic block 901. The elastic block 901 is squeezed and moves inward, thereby effectively driving the No. 1 arc spring piece 903 and the No. 2 arc spring piece 904 to bend inward. At this time, the spring 905 expands, thereby effectively buffering the force and preventing the glass from being damaged.
