Technical Field

[0001] The utility model relates to a paper pressing device and a binding machine. Background Art

[0002] At present, a binding machine is an office equipment that binds the object to be bound by binding threads or binding nails or hot melting of a rubber tube. In the binding machine, a paper pressing device is required to press the object to be bound. Chinese Patent with publication number CN208197904U discloses a mechanism for automatically releasing a paper presser. It touches the release screw on the motor base and pushes the release lever through the lever principle of the transmission rod, so that the locking block is in a horizontal state, and the paper presser rebounds to the original position under the action of the sleeve spring. In this mechanism, when the motor base moves downward, the paper presser presses the paper, and when the motor base moves upward, the paper presser is released. Although the linkage is realized, it is not suitable for the scenario where the paper presser does not need to be released when the motor base moves upward. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a paper pressing device that can well press the object to be bound and unlock the paper pressing component to reset it when the paper pressing component needs to be unlocked, which is convenient for use.

The locking rod is arranged on one of the locking and releasing plate and the paper pressing component, the locking hole is arranged on the other of the locking and releasing plate and the paper pressing component, the locking rod passes through the locking hole, and the elastic element acts on the locking and releasing plate to make the locking rod and the locking hole in an inclined state to at least lock the upward movement of the paper pressing component;

[0008] An actuating component connected to the locking and releasing plate, the actuating component is configured to: be actuated to act on the locking and releasing plate to swing the locking and releasing plate to the release position; when the locking and releasing plate is in the release position, the locking rod does not contact the locking hole so that the paper pressing component can move relatively automatically.

[0009] Further, the locking rod is arranged on the paper pressing component, and the locking hole is arranged on the locking and releasing plate.

[0010] Further, a contact member is provided on the locking and releasing plate, and the actuating member is cooperatively arranged with the contact member to actuate the locking and releasing plate.

[0011] Further, the actuating member includes:

[0012] A rotating wheel adapted to be driven to rotate, and an abutting wheel is provided at a non-central position of the rotating wheel. When the rotating wheel rotates, the abutting wheel is adapted to abut against the locking and releasing plate so that the locking and releasing plate swings.

[0013] Further, the actuating member further includes a motor, and the motor is connected to the rotating wheel to drive the rotating wheel to rotate.

[0014] Further, an opto-coupler sensing device is provided between the frame and the rotating wheel for indicating when the rotating wheel rotates to a first position or a second position. When the rotating wheel rotates to the first position, the locking and releasing plate swings to the release position; when the rotating wheel rotates to the second position, the locking rod and the locking hole are inclined to lock the upward movement of the paper pressing member.

[0015] The opto-coupler sensing device includes a cooperatively arranged opto-coupler member and a light-shielding plate.

The feeding mechanism includes a feeding pipe and a feeding wheel located below one side of the outlet of the feeding pipe and adapted to be driven to rotate. The feeding wheel is the rotating wheel of the actuating member.

[0020] With the above technical solution, the object to be stapled is placed on the platen of the stapler, and the paper pressing member is driven by the drilling member to move downward to press the object to be stapled. During this process, since the driving force of the drilling member driving the paper pressing member is greater than the stopping force when the locking rod and the locking hole are inclined, the paper pressing member can only move downward. However, due to the existence of the stopping force when the locking rod and the locking hole are inclined, the paper pressing member cannot move upward. When the paper pressing member moves downward to the in-place position, it can well press the object to be stapled. When unlocking is required, only the actuating member needs to be actuated, so as to drive the locking release plate to swing to the release position. The locking rod does not contact the locking hole, and the paper pressing member can move relatively automatically, so that the paper pressing member can be unlocked and reset.

[0023] In order to make the content of the present invention easier to be clearly understood, the present invention will be further described in detail below according to specific embodiments in conjunction with the drawings.

[0024] Embodiment 1

[0025] As Figures 1 - 2 shown, a paper pressing device includes:

[0026] a frame;

[0027] a paper pressing member 1 slidably fitted on the frame;

[0028] a locking release plate 2 hinged on the frame. A locking member is provided between the locking release plate 2 and the paper pressing member 1. The locking member includes a locking rod 31, a locking hole 32 and an elastic element. The locking rod 31 is provided on one of the locking release plate 2 and the paper pressing member 1, and the locking hole 32 is provided on the other of the locking release plate 2 and the paper pressing member 1. The locking rod 31 passes through the locking hole 32, and the elastic element acts on the locking release plate 2 to make the locking rod 31 and the locking hole 32 inclined to at least lock the upward movement of the paper pressing member 1;

[0029] an actuating member connected to the locking release plate 2. The actuating member is configured to: be actuated to act on the locking release plate 2 to swing the locking release plate 2 to the release position; when the locking release plate 2 is in the release position, the locking rod 31 does not contact the locking hole 32 to make the paper pressing member 1 move relatively automatically.

[0030] In this embodiment, two guide posts 10 are installed on the frame, and the paper pressing member 1 is slidably connected to the guide posts 10 up and down; in addition, a locking mounting bracket 21 is provided on the frame, and the locking release plate 2 can be specifically hinged to the locking mounting bracket 21 through a locking pin 22.

[0031] Place the object to be bound on the platen of the binding machine. The paper pressing member 1 is driven by the drilling member to move downward to press the object to be bound. During this process, since the driving force of the drilling member driving the paper pressing member 1 is greater than the stopping force when the locking rod 31 and the locking hole 32 are inclined, the paper pressing member 1 can only move downward. However, due to the existence of the stopping force when the locking rod 31 and the locking hole 32 are inclined, the paper pressing member 1 cannot move upward. When the paper pressing member 1 moves downward in place, it can well press the object to be bound. When unlocking is required, only need to operate the moving member, so as to drive the locking release plate 2 to swing to the release position, the locking rod 31 does not contact the locking hole 32, and the paper pressing member 1 can move relatively automatically, so that the paper pressing member 1 can be unlocked and reset.

[0032] Specifically, as Figures 1 - 2 shown, the paper pressing member 1 includes a paper pressing base 11. The specific structure of the paper pressing member 1 is prior art and will not be elaborated in this embodiment. It can refer to the paper pressing member 1 in the pressing head release mechanism of a full-automatic binding machine disclosed in a Chinese patent with the publication number CN210553716U, but not limited thereto.

[0033] In this embodiment, the locking rod 31 is arranged on the paper pressing member 1, and the locking hole 32 is arranged on the locking release plate 2.

[0034] In this embodiment, the elastic element is a spring, which is specifically connected between the lower part of the locking release plate 2 and the platen of the binding machine.

[0035] Specifically, a contact member 23 is provided on the locking release plate 2, and the moving member is cooperatively arranged with the contact member 23 to actuate the locking release plate 2.

[0036] In this embodiment, the contact member 23 is specifically a screw.

[0037] Specifically, as Figures 1 - 2 shown, the moving member can be specifically of the following structure, including:

[0038] A rotating wheel 41 adapted to be driven to rotate. An abutting wheel 42 is arranged at a non-central position of the rotating wheel 41. The abutting wheel 42 is adapted to abut against the locking release plate 2 when the rotating wheel 41 rotates, so that the locking release plate 2 swings.

[0039] Specifically, the moving member further includes a motor 43, and the motor 43 is connected to the rotating wheel 41 to drive the rotating wheel 41 to rotate.

[0040] In this embodiment, a feeding mounting bracket 72 is installed on the frame, and the rotating wheel 41 is rotatably connected to the feeding mounting bracket 72.

[0041] Specifically, an opto-coupler sensing device 5 for indicating when the rotating wheel 41 rotates to the first position or the second position is provided between the frame and the rotating wheel 41. When the rotating wheel 41 rotates to the first position, the locking release plate 2 swings to the release position; when the rotating wheel 41 rotates to the second position, the locking rod 31 and the locking hole 32 are inclined to lock the upward movement of the paper pressing member 1.

[0042] The opto-coupler sensing device 5 includes a cooperatively arranged opto-coupler and a light-shielding plate. When the light-shielding plate enters the opto-coupler, the rotating wheel 41 rotates to the first position, and when the light-shielding plate leaves the opto-coupler, the rotating wheel 41 rotates to the second position.

[0043] Specifically, the light-shielding plate is of a sector structure.

[0044] In this embodiment, when the light-shielding plate is not located within the opto-coupler, the rotating wheel 41 is in the second position, and the abutting wheel 42 on the rotating wheel 41 does not contact the non-pressing contact member 23 on the locking release plate 2. Under the action of the elastic element, the locking release plate 2 makes the locking rod 31 and the locking hole 32 inclined to at least lock the upward movement of the paper pressing member 1. When it is necessary to unlock the paper pressing member 1, the motor 43 needs to act to drive the rotating wheel 41 to rotate in one direction. When the rotating wheel 41 rotates to the first position, the abutting wheel 42 on the rotating wheel 41 abuts against the contact member 23, pressing down the locking release plate 2, causing the locking hole 32 to move. The original inclined locking rod 31 and locking hole 32 become perpendicular. At this time, the opto-coupler sensing device 5 senses and cooperates, that is, the light-shielding plate enters the opto-coupler, and the locking rod 31 does not contact the locking hole 32 to enable the paper pressing member 1 to move relatively automatically, and the paper pressing member 1 is unlocked from the locked state.
