[0003] Patent CN201820413413.6 discloses a paper receiving device for a folding machine. This solution uses a bidirectional lead screw connected to a support base to adjust the distance between two pressure rollers, thereby adjusting the extension distance of the pressure rollers and meeting the folding requirements of different specifications. However, this solution still has certain defects and shortcomings in actual use. First, the pressure force of the pressure rollers cannot be adjusted, and the pressure force and height of the pressure rollers cannot be adjusted according to the needs. In actual use, it is easy to be too tight or too loose. Second, the pressure rollers of this device lack elastic extension function, resulting in poor pressure effect. Therefore, improvements are needed. Utility Model Content

An annular body is installed at one end of the swing arm, rotatably connected to a corresponding circular slider. An angle adjustment mechanism is fixed at the middle of the limiting rod. When the pressing force of the pressure roller needs adjustment, the electric push rod within the angle adjustment mechanism is activated, pushing or pulling the push-pull rod, causing it to move within the groove of the swing arm. This controls the rotation of the swing arm, thereby adjusting the pressing force of the pressure roller. This method also allows for adjustment of the pressure roller's height, solving the problem of inconvenient pressure roller adjustment in current devices.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A paper receiving structure for a folding machine includes a frame and a conveyor belt connected to the frame. Support frames are fixedly connected to mounting plates on both sides of the frame. A bidirectional lead screw is rotatably connected between the two support frames.

The paper pressing assembly includes: an annular body rotatably connected to the corresponding circular slider; and a swing arm integrally formed on one side of the annular body, with a circular rod slidably connected to a through hole on one side of the swing arm. The end of the circular rod extends to the outside of the swing arm and is fixedly connected to a connecting cylinder. A removable paper pressing wheel is provided on the connecting cylinder.

[0009] Furthermore, a support rod is fixedly connected to one side of the paper pressing wheel, and bolts are provided at the connection between the support rod and the connecting cylinder.

[0010] Furthermore, a telescopic block is fixedly connected to one end of the round rod, the telescopic block is slidably connected to the corresponding rectangular cavity groove in the swing arm, and a spring is sleeved on the round rod, with the two ends of the spring abutting against the swing arm and the connecting cylinder respectively.

[0011] Furthermore, the circular slider includes a circular body threaded onto a bidirectional lead screw, and annular plates integrally formed on both sides of the circular body, with a groove formed between the two annular plates, and the annular body rotatably connected to the groove of the circular slider.

[0012] Furthermore, a limiting rod is fixedly connected between the two support frames. A limiting hole adapted to the limiting rod is opened at the corresponding position of the circular body.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a paper receiving structure for a folding machine, which has the following beneficial effects:

[0016] 1. This utility model involves threading two circular sliders onto a bidirectional lead screw, with a paper-pressing assembly installed on each slider. The paper-pressing assembly comprises an annular body, a swing arm, a round rod, a spring, a connecting cylinder, a paper-pressing wheel, a support rod, and a telescopic block. The swing arm has a slotted groove. When adjusting the pressing force of the paper-pressing wheel, the electric push rod in the angle adjustment mechanism is activated. The electric push rod can push or pull the push-pull rod, causing it to move within the slotted groove of the swing arm. This controls the rotation of the swing arm and the annular body on the corresponding circular slider, adjusting the pressing force of the paper-pressing wheel. This method also allows for adjusting the height of the paper-pressing wheel, offering good ease of use. The angle adjustment mechanism in this device is fixedly connected to the middle of the limiting rod. It should be noted that even after the circular sliders and the paper-pressing assembly have moved, the pressing force of the paper-pressing wheel can still be adjusted via the angle adjustment mechanism.

[0017] 2. This utility model, by fitting a spring on a round rod, with the two ends of the spring abutting between the swing arm and the connecting cylinder respectively, can realize the spring extension effect of the paper pressing wheel, so that the paper pressing wheel and the paper sheet can be effectively attached, ensuring the paper pressing effect of the paper pressing wheel.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1 and Figure 3 As shown in the figure, an embodiment of the present invention provides a paper receiving structure for a folding machine, including a frame 1 and a conveyor belt 2 connected to the frame 1. Support frames 5 are fixedly connected to mounting plates 4 on both sides of the frame 1. A bidirectional lead screw 6 is rotatably connected between the two support frames 5. Two symmetrically distributed circular sliders 8 are threaded onto the bidirectional lead screw 6. Each of the two circular sliders 8 is provided with a paper pressing assembly 3. The paper pressing assembly 3 includes: an annular body 301, rotatably connected to the corresponding circular slider 8; and a swing arm 302, integrally formed on one side of the annular body 301. A round rod 305 is slidably connected to a through hole on one side of the swing arm 302. The end of the round rod 305 extends to the outside of the swing arm 302 and is fixedly connected to a connecting cylinder 307. A removable paper pressing wheel 308 is provided on the connecting cylinder 307.

[0027] It should be noted that the frame 1 is the main part of the device. A conveyor belt 2 is set on the frame 1 for paper transfer. A mounting plate 4 is fixed on the side of the frame 1 for fixing the support frame 5. A bidirectional lead screw 6 is rotatably connected between the two support frames 5. When the bidirectional lead screw 6 rotates, it causes two circular sliders 8 to move towards each other, driving the corresponding paper pressing assembly 3 to move, thereby meeting the paper receiving requirements of different types of paper. The circular sliders 8 are circular in design, which facilitates the rotational connection of the annular body 301, thereby adjusting the angle of the swing arm 302 and adjusting the height of the paper pressing roller 308, thereby adjusting the pressing force of the paper pressing roller 308. The paper pressing roller 308 is detachably assembled on the connecting cylinder 307, which facilitates the assembly and replacement of the paper pressing roller 308. Different types of paper pressing rollers 308 can be used.

[0028] like Figure 3 As shown, in some embodiments, a support rod 309 is fixedly connected to one side of the paper pressing roller 308, and a bolt is provided at the connection between the support rod 309 and the connecting cylinder 307.

[0029] It should be noted that the support rod 309 is detachably assembled onto the connecting cylinder 307 by bolts, thereby enabling the detachable installation of the paper pressing roller 308.

[0030] like Figure 3As shown, in some embodiments, one end of the round rod 305 is fixedly connected to a telescopic block 3010, the telescopic block 3010 is slidably connected to a rectangular cavity 304 correspondingly opened in the swing arm 302, and a spring 306 is sleeved on the round rod 305, with the two ends of the spring 306 abutting against the swing arm 302 and the connecting cylinder 307 respectively.

[0031] It should be noted that the telescopic block 3010 is slidably connected to the rectangular cavity 304 of the swing arm 302 to realize the telescopic limit of the round rod 305 and the paper pressing wheel 308. By sleeved on the round rod 305, the damping extension of the paper pressing wheel 308 is realized, so that the paper pressing wheel 308 fits with the paper, thereby realizing the effective pressing of the paper.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the circular slider 8 includes a circular body 801 threadedly connected to the bidirectional lead screw 6, and annular plates 802 integrally formed on both sides of the circular body 801. A groove 803 is formed between the two annular plates 802, and the annular body 301 is rotatably connected to the groove 803 of the circular slider 8.

[0033] It should be noted that by setting an annular plate 802 and a groove 803 on the circular body 801, the rotational connection of the annular body 301 is facilitated, thereby making it easier to adjust the rotation angle of the swing arm 302.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a limiting rod 7 is fixedly connected between the two support frames 5. A limiting hole adapted to the limiting rod 7 is opened on the circular body 801 at the corresponding position of the limiting rod 7. An angle adjustment mechanism 9 is fixedly connected to the middle of the limiting rod 7. The angle adjustment mechanism 9 includes: a fixed seat 901, which is fixedly connected to the limiting rod 7; an electric push rod 903, which is rotatably connected to a rotary joint 902 provided on the lower surface of the fixed seat 901. A push-pull rod 905 is fixedly connected to a connecting seat 904 provided at the end of the output shaft of the electric push rod 903. The push-pull rod 905 is adapted to the corresponding strip groove 303 opened on the swing arm 302.

[0035] It should be noted that the setting of the limiting rod 7 can realize the extension and retraction limit of the circular body 801, ensuring the stable transmission of the circular slider 8. By fixing the angle adjustment mechanism 9 in the middle of the limiting rod 7, the rotation of the annular body 301 and the swing arm 302 can be controlled to adjust the pressing force and height of the paper pressing wheel 308. The angle adjustment mechanism 9 consists of a fixed base 901, a rotary joint 902, an electric push rod 903, and a push-pull rod 905. When it is necessary to adjust the pressing force of the paper pressing wheel 308, the electric push rod 903 is controlled to work, which can push or pull the push-pull rod 905, so that the push-pull rod 905 moves in the slot 303 of the swing arm 302, realizing the rotation control of the annular body 301 and the swing arm 302, thereby adjusting the pressing force of the paper pressing wheel 308. This method of adjustment is convenient, and the design of the angle adjustment mechanism 9 is more reasonable, which can save space and is more reasonable and ingenious overall.

[0036] like Figure 1 As shown, in some embodiments, a motor is mounted on one of the support frames 5, and the output shaft of the motor is coaxially connected and fixed to one end of the bidirectional lead screw 6.

[0037] It should be noted that the motor can drive the bidirectional lead screw 6 to rotate, thereby controlling the extension and retraction of the circular slider 8 and the paper pressing assembly 3, and thus meeting the paper receiving requirements of different types of paper.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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 this utility model should be included within the protection scope of this utility model.
