Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, in particular to a movable conveying device for extension. Background Art

[0002] When printing, the cardboard needs to be stacked. Since the feed belt is at a high altitude from the ground and the stacked cardboard is heavy, a lift is needed to lift the stacked cardboard so that the cardboard to be printed can be sent to the feed port of the feed belt. Due to the paper size and the structural limitations of the lift, for shorter cardboards, when they are stacked and placed on the lift, the distance from the feed port is often insufficient. If the stacked cardboard is directly placed on the end of the lift close to the feed belt, the unbalanced force will cause overturning or damage to the telescopic parts, and the stability of the lift plate cannot be guaranteed, which is prone to danger. The cost of directly replacing the printing press is too high, so only longer cardboard can be fed. In order to solve the problem of insufficient distance for short cardboard, feeding needs to be done manually, and the hand needs to reciprocate between the rotating roller and the conveyor belt, which is not only unsafe, but also has low feeding efficiency. In addition, if the extended feed belt is directly installed, although it can meet the needs of feeding short boards. However, once it is necessary to feed long-sized sheets, the extended belt needs to be disassembled, and the constant disassembly and assembly also affects the actual printing production efficiency.

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] Reference Figure 1 to Figure 3 A movable conveying device for extension includes a frame 1, a protrusion 15 is provided at one end of the frame 1, a connecting hole 16 is provided on the protrusion 15, the connecting hole 16 is in an arc shape, and the number of protrusions can be set according to the needs of different connection positions, such as two protrusions 15 are set, and the two protrusions 15 are set opposite to each other, and the connecting holes 16 are two correspondingly, and the movable conveying device and other devices are connected for use through the two opposite connecting holes 16. A first conveyor belt 11 is provided at the other end of the frame 1, and the first conveyor belt 11 is set horizontally, and also includes a telescopic device, which is connected to one side of the frame 1, and can provide support at the edge position of the entire extended conveying device, reduce the impact of the vibration of the first conveyor belt 11, and help to maintain the flatness of the first conveyor belt 11 at different angles, so that the cardboard runs on the first conveyor belt 11 more stably.

[0017] The telescopic device includes a cylinder 17, and the cylinder 17 is connected to the frame 1. For example, one side of the frame 1 is connected to the piston rod of the cylinder 17. At the same time, a bracket can be fixedly provided on the connected transmission device 2 or in addition, and the other end of the cylinder 17 can be connected to the bracket. In this way, the cylinder 17 can support the frame 1. At the same time, by providing an adjustment cylinder 17, when the piston rod is extended or contracted, it can be used to adjust the inclination angle of the frame 1. By adjusting the telescopic length of the cylinder 17, the stability and safety of the entire movable conveying device can be ensured while lifting.

[0018] The frame 1 is provided with a roller 13, and the roller 13 and the first conveyor belt 11 are correspondingly arranged. The roller 13 and the motor are electrically connected, and the feeding speed of the cardboard on the conveyor belt is flexibly adjusted by controlling the rotation speed of the roller. The flatness of the cardboard during feeding is maintained by the support and pressure of the roller 13. Both sides of the frame 1 are provided with connecting seats 12, and the roller 13 and the frame 1 are connected through two connecting seats 12. Furthermore, the connecting seat 12 is provided with an adjustment slot 14, and the roller 13 is connected to the connecting seat 12 through the adjustment slot 14. The upper and lower positions of the roller 13 can be adjusted through the adjustment slot 14 to meet the needs of the actual feeding pressure. After adjustment, the adjusting bolt is used to tighten.

[0019] The frame 1 is provided with a buffer plate 10, which is arranged between the protrusion 15 and the first conveyor belt 11, so that after the movable conveyor device is connected with the second conveyor belt, the buffer plate 10 serves as a transition between the two transmission devices 2, that is, the plate provides a temporary stop area between the two first conveyor belts 11, which helps to adjust the speed difference, so that the plate can slide smoothly from one first conveyor belt 11 to another first conveyor belt 11. After the extended movable conveyor device is installed, the entire conveyor device is not flat enough relative to the transmission device 2, or the speeds of the two first conveyor belts 11 are different, which prevents the plate from being offset or the card board from being damaged, so as to reduce the pause and blockage between the first conveyor belts 11 and improve the operation efficiency and flow of the entire conveyor device.

[0020] In order to facilitate connection and use, the movable conveying device also includes a transmission device 2, for example, the transmission device 2 includes a second conveyor belt and a bracket, and a transmission rod is provided at the bottom of the transmission device 2. When the transmission rod and the connecting hole 16 are matched, the transmission rod is inserted into the connecting hole 16, thereby completing the connection between the transmission device 2 and the frame 1, and the frame 1 can rotate around the transmission rod through the connecting hole 16. In this way, the two conveying devices are connected together as a large-scale extended conveying device. When the long-sized plates are transported, the piston rod of the cylinder is adjusted. When the piston rod contracts, the connecting hole 16 of the movable conveying device rotates around the transmission rod, so that the end of the entire extended conveying device away from the connecting hole rises. When it rises to the point where the first conveyor belt 11 and the second conveyor belt are nearly vertical, the long-sized plates can directly pass through the strip hole area 18 between the connecting hole 16 and the buffer plate 10, so that the transportation of the long-sized plates is not affected. When it is necessary to transport short-sized boards, the cylinder 17 is adjusted to extend the piston rod, and the entire added movable telescopic device is lowered. When it falls to a relative level with the transmission device 2, the overall feeding length of the transmission device 2 is lengthened, and the length of the feed port meets the feeding distance of short board materials, so that the entire device can transport short-sized cardboard. Therefore, the problem of switching between boards of different sizes is solved, and the applicability of the entire printing machine is improved. When long and short boards are printed in a cycle, there is no need to disassemble and assemble the entire extension device multiple times, which improves the actual printing production efficiency.

[0021] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
