Description

Technical Field

[0001] This utility model belongs to the field of folding machine technology, and in particular relates to a fence for folding machines. Background Technology

[0002] A folding machine is a device that folds large sheets of paper and is widely used in printing, publishing, packaging, advertising, and other industries. The folding gate is one of the key components in a folding machine for completing the paper folding process. Currently, during folding, the paper is fed into the gate, blocked by a stop, and then pulled by a roller to complete a fold. This process continues until the paper is folded. However, when the folding machine no longer folds the paper, the gate needs to be removed and replaced with another mechanism so that the paper is directly fed to the next process after passing through that position. This method has the following problems:

[0003] When switching between folding and non-folding processes, the machine needs to be stopped for disassembly and assembly, which seriously affects work efficiency.

[0004] During the disassembly and assembly process, it is necessary to remove and place the folding machine's supporting mechanisms, such as the fences, before and after disassembly and assembly. These mechanisms are heavy, require a lot of labor for workers, and also pose certain safety hazards. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a folding machine fence that allows for seamless switching between folding and non-folding processes without requiring the fence to be removed.

[0006] The technical solution provided by this utility model is: a folding machine fence, including a first fence plate and a second fence plate assembled together in a stacked manner, with a stacking gap between the first fence plate and the second fence plate, and multiple corresponding sliding grooves provided on both the first fence plate and the second fence plate, with one end of all the sliding grooves on the first fence plate passing through the end of the first fence plate.

[0007] A flipping and positioning assembly extending into the slide groove and driven by a power device is slidably installed between the first fence panel and the second fence panel; the second fence panel is provided with a plurality of guide plates, which are disposed at the end of the slide groove.

[0008] As an improvement, the flip positioning assembly includes a slide block that slides with the first fence plate and is connected to the power device. The slide block is provided with a plurality of protruding blocking positioning blocks located in the slide groove. The end of the blocking positioning block on the same side as the through end of the slide groove is provided with a concave arc-shaped groove.

[0009] It also includes a connecting seat that is connected to the slide and slidably engaged with the second fence plate, wherein the first fence plate and the second fence plate are located between the slide and the connecting seat.

[0010] As a further improvement, the slide and all the blocking positioning blocks are integrally formed, and the slide between two adjacent blocking positioning blocks is provided with a groove.

[0011] As a further improvement, pads are provided between the slide and the first fence plate, between the first fence plate and the second fence plate, and between the second fence plate and the connecting seat.

[0012] As a further improvement, a drive support plate is provided on the side of the slide near the first fence plate, and the drive support plate is connected to the power device.

[0013] As a further improvement, the drive plate is provided with a bending portion that bends away from the first fence plate.

[0014] As a further improvement, the power unit includes mounting seats disposed on the first fence plate and distributed on both sides of the first fence plate, a rotating shaft rotatably mounted between the two mounting seats, a belt drive mechanism being provided between the rotating shaft and the first fence plate, and the drive plate being connected to the drive belt on the belt drive mechanism.

[0015] One end of the shaft is equipped with a drive wheel.

[0016] As an improvement, both the first fence plate and the second fence plate near the through end of the chute are provided with connecting plates, and the connecting plates are provided with clearance grooves, which are corresponding to the chute.

[0017] As a further improvement, the guide piece is integrally formed on the second fence plate, and the guide piece is inclined through the avoidance groove on the second fence plate.

[0018] As a further improvement, the guide plate is provided with two guide plates and is located at the ends of the slide grooves on both sides of the second fence plate.

[0019] By adopting the above-described technical solution, the beneficial effects of the folding machine fence provided by this utility model are as follows:

[0020] The folding machine's gate comprises a first gate plate and a second gate plate assembled on top of each other, with a stacking gap between them. Both the first and second gate plates have multiple corresponding sliding grooves, with one end of each groove on the first gate plate extending through the end of the first gate plate. A flipping and positioning assembly, driven by a power unit, is slidably installed between the first and second gate plates, extending into the sliding groove. The second gate plate has multiple guide pieces located at the ends of the sliding grooves. Based on this structure, when the paper needs to be folded, the power unit drives the flipping and positioning assembly to slide along the sliding groove to the appropriate position (according to the folding direction). (Size adjustment) At this time, the position of the flip positioning component is not at the end of the slide groove through end on the first grid plate. Then, the paper enters the overlapping gap between the first grid plate and the second grid plate. Then, the flip positioning component blocks the paper and the rubber roller on the folding machine pulls the paper to complete the folding work. When the paper does not need to be folded, the power unit drives the flip positioning component to slide to the end of the slide groove through end and makes the blocking part of the flip positioning component protrude from the end of the first grid plate and the second grid plate. During the sliding, the flip positioning component is guided by the guide plate. After being conveyed, it is directly conveyed to the downstream process by the blocking part on the flip positioning component.

[0021] In summary, this folding machine uses a grid system to allow for seamless switching between folding and non-folding processes without stopping the machine, effectively ensuring work efficiency. Furthermore, it eliminates the need for disassembly, significantly reducing the workload for workers and ensuring high safety.

[0022] The flip positioning assembly includes a slide block that slides with the first grid plate and is connected to a power device. The slide block has multiple protruding blocking positioning blocks located in the groove. The end of the blocking positioning block on the same side as the through end of the groove has a concave arc-shaped groove. It also includes a connecting seat that connects to the slide block and slides with the second grid plate. The first grid plate and the second grid plate are located between the slide block and the connecting seat. In use, the slide block is driven by the power device to move the flip positioning assembly, the blocking positioning blocks block the paper, and the arc-shaped groove guides the paper. The structure is simple and the design is ingenious, laying the foundation for the free switching of paper between folding and non-folding processes.

[0023] Since the slide block and all the blocking positioning blocks are integrally molded, and the slide block between two adjacent blocking positioning blocks is provided with a groove, the overall structural strength between the slide block and all the blocking positioning blocks is guaranteed by this structure; the groove is used to achieve good avoidance with the first fence plate and avoid mutual interference.

[0024] Because pads are provided between the slide and the first fence plate, between the first fence plate and the second fence plate, and between the second fence plate and the connecting seat, the wear problem caused by friction during sliding is avoided through the transition of the pads.

[0025] Since a drive plate is provided on the side of the slide near the first fence plate, and the drive plate is connected to the power unit, the connection between the slide and the power unit is realized through the transition of the drive plate, which improves the ease of assembly.

[0026] Because the drive plate has a bending section that bends away from the first fence plate, the structural strength of the drive plate itself is increased by the bending section.

[0027] The power unit includes mounting seats set on the first fence plate and distributed on both sides of the first fence plate. A rotating shaft is rotatably mounted between the two mounting seats. A belt drive mechanism is provided between the rotating shaft and the first fence plate. The drive plate is connected to the drive belt on the belt drive mechanism. One end of the rotating shaft is provided with a drive wheel. When the flip positioning component is driven, the drive wheel drives the rotating shaft to rotate. The rotating shaft drives the belt drive mechanism to work. The drive belt drives the drive plate and the slide connected to it to move. The structure is simple, the driving effect is good, and the weight is light.

[0028] Since both the first and second fence plates near the through end of the chute are equipped with connecting plates and clearance grooves, which are corresponding to the chute, the connecting plates ensure the coplanarity and structural strength of the first and second fence plates after the chute is opened. The clearance grooves are used to avoid the moving blocking positioning block, effectively preventing the connecting plates from interfering with the blocking positioning block on its travel path.

[0029] Since the guide plate is integrally formed on the second fence plate, and the guide plate passes obliquely through the clearance groove on the second fence plate, this structure not only ensures the structural strength between the guide plate and the second fence plate, but also further avoids the problem of interference between the connecting plate and the blocking positioning block during the sliding of the slide.

[0030] Because the guide plate has two grooves located on both sides of the second fence plate, it not only does not affect the normal guiding of the blocking positioning block, but also simplifies the structure and reduces the difficulty of processing and manufacturing.
