Abstract
Description
Technical Field
[0001] This utility model relates to the field of adjustment technology for printing folding machines, and in particular to a pull-out blade changing mechanism for a folding machine. Background Technology
[0002] Folding machines are modern printing equipment that emerged alongside the modern printing industry. They are instruments used to fold papers of various sizes and thicknesses within a design scope. For example, Chinese patent CN202421308373.0 discloses a thick paper folding machine that connects three folding devices together through a corner-style machine arrangement. A grid-type folding machine handles longitudinal folding of the paper, while two transverse folding mechanisms handle transverse folding, producing paper with multiple creases in both the horizontal and vertical directions to meet usage requirements. However, its first and second folding blades are both located inside the machine, making blade changing inconvenient for the operator and reducing blade changing efficiency. Utility Model Content
[0003] In view of this, the present invention provides a pull-out blade changing mechanism for a folding machine to solve the above problems.
[0004] A pull-out blade changing mechanism for a folding machine includes a body, a blade holder assembly passing through the body, and a locking component disposed on the body and located on one side of the blade holder assembly. The blade holder assembly includes a frame, a blade holder mounted on the frame, and two bidirectional slide rails respectively disposed on both sides of the frame. The locking component includes a fixing block fixedly disposed on the body, a pull rod movably passing through the fixing block, and a spring disposed on the fixing block. A stepped portion is provided on the side of the frame facing the locking component, one side of which has a slope, one end of which abuts against and smoothly transitions to the side of the frame. A pad is provided on the end of the pull rod facing the blade holder assembly, the end of which is rounded and smooth. The pad on the pull rod is positioned along the movement path of the stepped portion. The spring is sleeved on the pull rod, one end of which abuts against the fixing block, and the other end of which abuts against the pad.
[0005] Furthermore, an opening is provided on one side of the fuselage.
[0006] Furthermore, a handle is provided on the side of the frame near the opening.
[0007] Furthermore, the blade holder is provided with a number of blade clips at intervals, and the blade clips are equipped with folding blades for folding pages.
[0008] Furthermore, the two sides of the bidirectional slide rail are respectively located on the side of the machine body opposite to the frame.
[0009] Furthermore, a circular groove is provided on the fixing block for the pull rod to pass through.
[0010] Compared with existing technologies, the pull-out blade changing mechanism on the folding machine provided by this utility model unlocks the frame by pulling the lever, thereby pulling out the frame to facilitate blade changing operations for the operator. When it is necessary to lock the frame, simply push the frame back, and the pad slides down the inclined surface under the spring's rebound and abuts against one side of the step, thereby locking the main frame. This pull-out blade changing mechanism on the folding machine eliminates the need for the operator to change blades inside the machine body, improving blade changing efficiency and facilitating the operator's blade changing operations.

[0013] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.
[0014] like Figure 1 The diagram shows a schematic of the pull-out blade changing mechanism on a folding machine provided by this invention. The pull-out blade changing mechanism includes a machine body 10, a blade holder assembly 20 passing through the machine body 10, and a locking assembly 30 disposed on the machine body 10 and located on one side of the blade holder assembly 20. It is conceivable that the pull-out blade changing mechanism on the folding machine also includes other functional modules, such as an assembly module and folding blades, which are technologies known to those skilled in the art and will not be described in detail here.
[0015] The body 10 is used to support the various components so that they can cooperate in various ways to complete the blade changing operation of the folding machine. An opening 11 is provided on one side of the body 10 to pull out the blade holder assembly 20.
[0016] The tool holder assembly 20 includes a frame 21, a tool holder 22 mounted on the frame 21, and two bidirectional slide rails 23 respectively disposed on both sides of the frame 21.
[0017] Please see Figure 2The frame 21 is housed within the body 10, and a handle 24 is provided on the side near the opening 11 to allow the operator to pull the frame 21 out of the body 10. A step 25 is provided on the side of the frame 21 near the handle 24 and facing the locking assembly 30. The side of the step 25 away from the handle 24 has a ramp 26, the end of which abuts against and smoothly transitions to the side of the frame 21. The step 25 cooperates with the locking assembly 30 to lock the tool holder assembly 20; the specific cooperation will be described below.
[0018] The blade holder 22 is provided with a number of blade clips 27 at intervals, and the blade clips 27 are clamped with folding blades for folding pages.
[0019] The bidirectional slide rail 23 is a slide rail system capable of smooth sliding in two opposite directions, with its length direction parallel to the arrangement direction of the plurality of blade clips 27. The main function of the bidirectional slide rail 23 is to allow two objects to move freely in two directions. The two sides of the bidirectional slide rail 23 are respectively located on the side of the machine body 10 opposite to the frame 21, allowing the frame 21 to slide along the bidirectional slide rail 23 and thus pull the frame 21 out of the opening 11. The bidirectional slide rail 23 itself is prior art and will not be described in detail here.
[0020] The locking assembly 30 includes a fixing block 31 fixedly mounted on the body 10, a pull rod 32 movably passing through the fixing block 31, and a spring 33 mounted on the fixing block 31.
[0021] The fixing block 31 is located at the opening 11, and a through circular groove is provided on it for the pull rod 32 to pass through.
[0022] A pad 34 is provided at the end of the pull rod 32 facing the tool holder assembly 20. The edge of the pad 34 is smooth and rounded to reduce the friction between the frame 21 and the pull rod 32 during movement and to facilitate sliding over the inclined surface 26. The pad 34 on the pull rod 32 is located on the movement path of the step portion 25. Thus, when the frame 21 is fully located in the machine body 10, the pad 34 is located on one side of the step portion 25 and abuts against each other to lock the frame 21 in place.
[0023] The spring 33 is sleeved on the pull rod 32. One end of the spring 33 abuts against the fixing block 31, and the other end abuts against the pad 34. In its free state, the spring 33 pushes the pad 34 and the pull rod 32 towards the frame 21 through its own elastic force, so that the pad 34 is tightly against the frame 21. Thus, when it is necessary to unlock the frame 21, simply pull the pull rod 32, so that the pad 34 is away from the step portion 25 and no longer abuts against each other, thereby unlocking the frame 21 and pulling it out. At this time, the spring 33 is compressed. When it is necessary to lock the frame 21, the pull rod 32 is released. At this time, the spring 33 returns to its original state and pushes the pad 34 back against the frame 21 through its own elastic force. Simply push the frame 21 back, and the pad 34 slides down the inclined surface 26 under the spring 33's rebound and abuts against one side of the step portion 25, thereby locking the frame 21.
[0024] Compared with the prior art, the pull-out blade changing mechanism on the folding machine provided by this utility model unlocks the frame 21 by pulling the pull rod 32, thereby pulling out the frame 21 to facilitate blade changing operations for the operator. When it is necessary to lock the frame 21, simply push the frame 21 back, and the pad 34 slides down the inclined surface 26 under the return of the spring 33 and abuts against one side of the step portion 25, thereby locking the main frame 21. The pull-out blade changing mechanism on the folding machine eliminates the need for the operator to change blades inside the machine body, improving blade changing efficiency and facilitating blade changing operations for the operator.
[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
