Description

Technical Field

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

[0002] Folding machines are mainly used for folding various sizes and thicknesses of paper within the design range. They are suitable for high-volume folding in fast printing centers, manufacturing enterprises, official documents, and business letters, and are generally used for double-page or four-page folding.

[0003] In the prior art, a Chinese utility model patent with publication number CN214495164U, entitled "A Knife-Type Folding Machine," utilizes a cylinder to move a folding blade up and down to fold the paper on the folding cover plate. When using this type of folding machine, problems arise where the paper cannot accurately reach the correct position on the folding cover plate, thus failing to fold neatly. For example, if the paper is too small, the paper feeding platform of the folding machine may not push the paper onto the two folding cover plates, or the paper may not be evenly distributed between the two folding cover plates, ultimately resulting in the paper not being folded or folding off-center. Utility Model Content

[0004] The purpose of this utility model is to provide a folding mechanism and a folding machine to solve the problem.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A folding mechanism includes a frame, a paper feed table, a creasing arm, and a shaping roller. The paper feed table, the creasing arm, and the shaping roller are all mounted on the frame. The creasing arm and the shaping roller are positioned from top to bottom at the folding opening of the paper feed table, with the working end of the creasing arm directly opposite the roll gap of the shaping roller.

[0007] Both the shaping rollers and the belt conveyor on the paper feeding table are driven by electric motors.

[0008] A further technical solution is as follows: the creasing arm includes a horizontal arm, a slide, a cylinder, and a creasing knife. The horizontal arm is mounted on the frame, the slide is slidably mounted on the horizontal arm and locked by bolts, the cylinder is mounted vertically downward on the slide, and the creasing knife is mounted on the power output end of the cylinder and is arranged parallel to the paper feeding table.

[0009] A further technical solution is to provide an anti-stick plate on the indentation arm.

[0010] A further technical solution is: a paper presser is provided on the paper feeding table. The paper presser includes a boat-shaped pressure bar, a crossbar, a rotating shaft, and a support. The two ends of the crossbar are connected by two rotating shafts respectively. One of the rotating shafts is rotatably installed on the paper feeding table. Several boat-shaped pressure bars are installed on the crossbar along the paper forward direction and form a paper feeding channel between them and the paper feeding table. One of the rotating shafts is placed on the support on the paper feeding table.

[0011] An automatic folding machine includes at least one of the aforementioned folding mechanisms.

[0012] A further technical solution is: a transition bridge is provided between the two folding mechanisms. The transition bridge includes a transition pressure plate, a variable angle conveyor, and a ball bearing plate. The two ends of the variable angle conveyor are respectively connected to the beginning and end of the two folding mechanisms. The transition pressure plate is installed on the inclined section of the variable angle conveyor, and the ball bearing plate is installed on the horizontal section of the variable angle conveyor.

[0013] A further technical solution is: a discharge platform is provided below the folding opening of the folding mechanism at the end, and the discharge end of the discharge platform is connected to the layered paper receiving device.

[0014] A further technical solution is that the discharge end of the paper feeding table of the folding mechanism at the end is connected to the infeed end of the lifting paper receiving table.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0016] This utility model proposes a folding mechanism and a folding machine. The folding mechanism has a folding opening on the paper feeding table, and a creasing arm and a shaping roller are installed from top to bottom at the folding opening on the paper feeding table. The creasing arm creates a crease on the paper, allowing the paper to enter between the shaping rollers, thus completing the double folding of the paper. Moreover, the belt conveyor on the paper feeding table can continuously carry the paper forward, and regardless of the size of the paper, it can deliver the paper to the appropriate position on the paper feeding table to ensure the folding effect.

[0031] Example 1:

[0032] This implementation example Figure 1 , Figure 2 and Figure 3 As shown, a folding mechanism 1 includes a frame 11, a paper feeding table 12, a creasing arm 13, and a shaping roller 14. The paper feeding table 12, the creasing arm 13, and the shaping roller 14 are all mounted on the frame 11. The creasing arm 13 and the shaping roller 14 are arranged from top to bottom at the folding opening of the paper feeding table 12, and the working end of the creasing arm 13 is directly opposite the roller gap of the shaping roller 14. The belt conveyors on the shaping roller 14 and the paper feeding table 12 are both driven by electric motors.

[0033] The paper is fed to the inlet of the paper feeding table 12 of the folding mechanism 1 by manual operation or in conjunction with automated equipment (such as slitting machine, paper feeder, etc.). Then, it reaches the folding opening of the paper feeding table 12 via a belt conveyor. At this time, the working end of the creasing arm 13 is facing downward. The creasing arm 13 creates a crease on the paper, allowing the paper to enter between the shaping rollers 14, completing the double folding of the paper. Moreover, the belt conveyor on the paper feeding table 12 can carry the paper forward continuously. Regardless of the size of the paper, it can be transported to the appropriate position on the paper feeding table 12 to ensure the folding effect.

[0034] Preferably, the creasing arm 13 includes a horizontal arm 131, a slide 132, a cylinder 133, and a creasing knife 134. The horizontal arm 131 is mounted on the frame 11, the slide 132 is slidably mounted on the horizontal arm 131 and locked by bolts, the cylinder 133 is mounted vertically downward on the slide 132, and the creasing knife 134 is mounted on the power output end of the cylinder 133 and is arranged parallel to the paper feeding table 12.

[0035] When the width of the paper changes, the position of the creasing knife 134 can be moved using the slide 132 to achieve paper folding.

[0036] Preferably, an anti-stick plate 15 is provided on the indentation arm 13.

[0037] When the creasing knife 134 presses the paper between the shaping rollers 14, and when the creasing knife 134 rises, paper may...

[0038] Preferably, a paper presser 16 is provided on the paper feeding table 12. The paper presser 16 includes a boat-shaped presser 161, a crossbar 162, a rotating shaft 163, and a support 164. The two ends of the crossbar 162 are connected by two rotating shafts 163 respectively. One of the rotating shafts 163 is rotatably mounted on the paper feeding table 12. Several boat-shaped pressers 161 are mounted on the crossbar 162 along the paper forward direction and form a paper feeding channel between them and the paper feeding table 12. One of the rotating shafts 163 is placed on the support 164 on the paper feeding table 12.

[0039] The boat-shaped pressure bar 161 facilitates paper feeding and also prevents paper from wrinkling. In addition, if there is a problem with the paper, the pressure bar 16 can be flipped up to remove the paper or for inspection.

[0040] Example 2:

[0041] Based on the above embodiments, this embodiment shows an automatic folding machine, which includes at least one folding mechanism.

[0042] A single folding mechanism can only achieve a double fold when working alone. Using one folding mechanism in combination can achieve a four-page fold, using three folding mechanisms in combination can achieve an eight-page fold, and so on, thus forming an automatic folding machine that can perform multiple folds.

[0043] Preferably, a transition bridge 2 is provided between the two folding mechanisms. The transition bridge 2 includes a transition pressure plate 21, a variable angle conveyor 22, and a ball bearing plate 23. The two ends of the variable angle conveyor 22 are respectively connected to the beginning and end of the two folding mechanisms. The transition pressure plate 21 is installed on the inclined section of the variable angle conveyor 22, and the ball bearing plate 23 is installed on the horizontal section of the variable angle conveyor 22.

[0044] The pressure plate 21 is used to smoothly pass the paper between the two folding mechanisms.

[0045] Preferably, a discharge platform 3 is provided below the folding opening of the end folding mechanism, and the discharge end of the discharge platform 3 is connected to the layered paper receiving device 4.

[0046] The structure and working principle of the layered paper receiving device 4 can be referred to the Chinese utility model patent with publication number CN220617837U entitled "A Layered Paper Receiving Device" by the applicant. Both the upper and lower paper receiving units can be used independently without limiting the workload of the equipment. The design is more user-friendly and is used to temporarily store a large number of folded pages (which are generally not folded by the final folding mechanism) so that the machine will not stop due to the inability to collect the pages.

[0047] Preferably, the discharge end of the paper feeding table 12 of the end folding mechanism is connected to the feed end of the lifting paper receiving table 5.

[0048] The lifting paper receiving table 5 consists of a motor, a lead screw, and a lifting platform with a belt conveyor. The motor drives the lead screw to rotate, causing the lifting platform to slide up and down along the frame of the lifting paper receiving table 5, which is used to collect the paper folded by the final folding mechanism.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
