Description

Technical Field

[0001] The invention belongs to the technical field of paper feeding facilities and equipment, and in particular relates to a differential separation paper feeding mechanism. Background Art

[0002] Paper is a carrier for writing and printing. It can be used for writing and drawing. It can also be used to carry information or as packaging materials, sanitary materials, etc. Specifically, the types of paper include printing paper, carbon paper, toilet paper, facial tissue, etc. It can also be business cards, certificates, or playing cards, etc. When paper is produced and processed or when paper is needed for corresponding work, it is necessary to use a paper feeding mechanism to transport the paper. Before transporting the paper, the staff will stack the paper on top of the feeding mechanism, and then the equipment will separate the placed cardboard through the feeding mechanism. Because the air between the papers is squeezed out when the papers are stacked, adjacent papers will often be adsorbed together. After separation is completed, the corresponding outward transportation work is carried out. The existing paper feeding mechanism generally uses a paper feeding head to separate and pick up the paper after the whole is assembled, and then the whole body is moved horizontally to feed the paper. However, existing paper feeding mechanisms not only have a high failure rate and low efficiency in separating and removing paper, but also can cause stacked sheets of paper to stick together. When the paper feed head picks up the top sheet, the lower sheets often follow the upper sheets, making it difficult to separate. This can result in paper not being delivered or over-delivering, impacting the user experience. Furthermore, problems require manual separation, which, if not performed, can lead to errors, increasing the workload and negatively impacting work efficiency, significantly affecting work stability. Furthermore, existing paper feeding mechanisms are generally complex, have numerous components, occupy a large volume, and consume high amounts of energy.

DETAILED DESCRIPTION

[0022] In order to more clearly understand the technical essence and beneficial effects of the present invention, a detailed description will be given below in the form of embodiments. However, the description of the embodiments does not limit the scheme of the present invention. Any equivalent transformation that is merely formal and not substantial based on the concept of the present invention should be regarded as within the scope of the technical scheme of the present invention.

[0023] In the following description, all concepts related to directionality or orientation, such as up, down, left, right, front and back, are based on Figure 1 The position state is used as a reference, and therefore it cannot be understood as a special limitation on the technical solution provided by the present invention. Example 1

[0024] See also Figure 1 and Figure 2, shows a differential separation paper feeding mechanism, including a frame 1, a loading platform 2, a separation roller assembly 3, a paper feeding roller assembly 4 and a power mechanism 5; the aforementioned frame 1 includes two frame side panels 11 arranged at intervals and a frame transverse plate 12 connected to the front end of the bottom of the two frame side panels 11, the two frame side panels 11 are arranged vertically, and the frame transverse plate 12 is arranged horizontally, the upper part of the aforementioned frame transverse plate 12 and the space corresponding to the two frame side panels 11 constitute a paper feeding area 13, and the space between the two frame side panels 11 and the rear end of the frame transverse plate 12 constitutes a separation area 14; the aforementioned loading platform 2 is used to dock with the aforementioned separation area 14 and transport the paper material to the separation area 14. In this embodiment, the loading platform 2 can realize up and down reciprocating motion and bear the load under the drive of an external driving device. The separation roller assembly 3 includes a separation roller 31, a separation roller 32 and a separation transmission wheel 33. The separation roller 31 is rotatably mounted between the two frame side plates 11 at a position close to the feeding area 13 in the separation area 14. The separation roller 32 is fixed on the separation roller 31 and corresponds to the upper position of the loading platform 2. During operation, the separation roller 32 rotates clockwise to separate a single paper from the stacked paper material and convey it to the paper feeding area 13. The separation transmission wheel 33 is arranged at the right end of the separation roller 31, and a one-way bearing 34 is arranged between the separation transmission wheel 33 and the separation roller 31. The one-way bearing 34 is used to realize the power transmission engagement and power transmission cutoff between the separation transmission wheel 33 and the separation roller 31; as shown in FIG. Figure 1 As shown in the figure, the aforementioned paper feed roller assembly 4 includes a paper feed roller 41, a paper feed roller 42 and a paper feed transmission wheel 43. The aforementioned paper feed roller 41 is rotatably mounted between the two frame side plates 11 at a position corresponding to the paper feed area 13, and the aforementioned paper feed roller 42 is fixed on the paper feed roller 41 and corresponds to the upper position of the frame transverse plate 12. The aforementioned paper feed transmission wheel 43 is arranged at the right end of the aforementioned paper feed roller 41; the aforementioned power mechanism 5 is transmission-connected with the aforementioned separation roller assembly 3 and the paper feed roller assembly 4, and the aforementioned separation roller transmission wheel 33 and the feeding transmission wheel 43 can be driven independently, and the power mechanism 5 can realize differential rotation between the separation roller 31 and the paper feed roller 41 and the rotation speed of the separation roller 31 is lower than the rotation speed of the paper feed roller 41.

[0025] As for the working mode of the one-way bearing 34: the outer ring of the one-way bearing 34 is connected to the separation transmission wheel 33, and the inner ring of the one-way bearing 34 is connected to the separation roller 31. The one-way bearing 34 belongs to the existing technology. When it is necessary to realize the rotation of the separation roller 32 to separate the paper, the power mechanism 5 drives the separation transmission wheel 33 and the paper feeding transmission wheel 43 to rotate clockwise, and the separation transmission wheel 33 applies a clockwise force to the one-way bearing 34. At this time, when the outer ring speed of the one-way bearing 34 exceeds the inner ring speed, the inner and outer rings of the one-way bearing 34 are combined, thereby transmitting the kinetic energy of the separation transmission wheel 33 to the separation roller 31, and the separation transmission wheel 33 can drive the separation roller 31 and the separation roller 32 to rotate clockwise. The separation roller 32 conveys the leading edge of a single paper forward to the lower part of the paper feeding roller 42. Since the rotation speed of the paper feeding roller 41 is greater than the rotation speed of the separation shaft 31, the paper feeding roller 42 conveys the single paper outward. In the process of the paper feeding roller 42 rolling and conveying the paper, since the trailing edge of the paper is still between the separation roller 31 and the loading platform 2, the paper moves faster under the drive of the paper feeding roller 42. The trailing edge of the paper exerts a force on the separation roller 32, and the clockwise rotation speed of the separation roller 32 and the separation roller 31 accelerates. At this time, the inner ring rotation speed of the one-way bearing 34 is higher than the outer ring rotation speed. The inner and outer rings of the one-way bearing 34 are in a separated state and rotate relatively independently, thereby cutting off the power transmission from the separation roller 31 to the separation transmission wheel 33, so that the separation transmission wheel 33 will not be subjected to the force exerted by the separation roller 31.

[0026] In this embodiment, the radial diameter of the aforementioned separation transmission wheel 33 is greater than the radial diameter of the aforementioned paper feeding transmission wheel 43; and the aforementioned power mechanism 5 has a power motor 51, a first transmission belt I 52 and a second transmission belt II 53, the power motor 51 is arranged at a lower position of the aforementioned frame transverse plate 12, and the power motor 51 includes a power motor output shaft 511, a power motor transmission member 512 is installed on the power motor output shaft 511, a first connecting groove I 5121 and a second connecting groove II 5122 are opened on the power motor transmission member 512, the aforementioned first transmission belt I 52 is installed on the aforementioned separation transmission wheel 33 and the power motor transmission member 512 It is also arranged in the first connecting groove I5121, and the aforementioned second transmission belt II53 is installed on the aforementioned paper feeding transmission wheel 43 and the power motor transmission member 512 and is arranged in the second connecting groove II5122. The aforementioned power motor 51 can realize the differential rotation of the separation transmission wheel 33 and the paper feeding transmission wheel 43 through the power motor output shaft 511 and through the first transmission belt I52 and the second transmission belt II53; specifically, due to the difference between the diameter of the separation transmission wheel 33 and the diameter of the aforementioned paper feeding transmission wheel 43, power is output through the power motor output shaft 511, so that the rotation speed of the separation transmission wheel 33 is greater than the rotation speed of the paper feeding transmission wheel 43, the structure is compact and space is saved.

[0027] It should be noted that, in this embodiment, the separation transmission wheel 33 and the paper feeding transmission wheel 43 are pulleys, and the first transmission belt I52 and the second transmission belt II53 are belts, and the differential rotation of the separation transmission wheel 33 and the paper feeding transmission wheel 43 is achieved by pulley transmission; of course, a sprocket transmission mechanism is adopted between the separation transmission wheel 33, the paper feeding transmission wheel 43 and the first transmission belt I52 and the second transmission belt II53, that is, the separation transmission wheel 33 and the paper feeding transmission wheel 43 are gears, and the first transmission belt I52 and the second transmission belt II53 are chains. Any change in transmission form is within the scope of protection of this patent and will not be elaborated here.

[0028] Furthermore, in this embodiment, the aforementioned separation roller assembly 3 is arranged at an upper position of the aforementioned loading platform 2, and the aforementioned frame transverse plate 12 is arranged at a lower position of the aforementioned paper feeding roller assembly 4 and corresponds to the front end position of the aforementioned separation roller assembly 3; when paper needs to be conveyed, the loading platform 2 can rise and press the material pile to the bottom of the paper feeding separation roller 32 of the separation roller assembly 3 and convey the paper toward the paper feeding roller assembly 4 through the drive of the separation roller 32.

[0029] Furthermore, a separation roller bearing 311 is provided at the connection between the separation roller 31 and the two frame side plates 11 of the frame 1 , and the separation roller 31 body passes through the two separation roller bearings 311 and rotates therewith.

[0030] Furthermore, a paper feed roller bearing 411 is provided at the connection between the paper feed roller 41 and the two frame side plates 11 of the frame 1 , and the paper feed roller 41 body passes through the two paper feed roller bearings 411 and rotates therewith.

[0031] See also Figure 1 , multiple loading platform positioning plates 21 are formed on the left and right edges of the aforementioned loading platform 2, and frame side plate clearance grooves 111 are opened at the bottom of the frame side plates 11 on both sides of the aforementioned frame plate 1 at the positions corresponding to the aforementioned loading platform positioning plates 21. The shape and size of the aforementioned frame side plate clearance grooves 111 are adapted to the contours of the loading platform positioning plates 21, and the loading platform positioning plates 21 can move back and forth up and down in their respective corresponding frame side plate clearance grooves 111.

[0032] In this embodiment, the one-way bearing 34 is preferably a high-temperature resistant sealed bearing.

[0033] Furthermore, the separation roller 32 and the paper feeding roller 42 are both made of rubber.

[0034] Please combine Figure 1 and Figure 2 The applicant briefly describes the working principle of the technical solution of the present invention: Figure 2Also shown is paper 6, which can be, for example, printed paper, book cover paper, and poker cards. At this time, the separation roller 32 and the paper feeding roller 42 are at the upper position of the paper 6. When the paper 6 needs to be transported outward, the material pile formed by the stacked paper 6 is placed on the loading platform 2. The loading platform 2 can be raised and lowered and press the material pile to the bottom of the paper feeding separation roller 32. Then, the power motor 51 of the power mechanism 5 is started to make it work. The separation transmission wheel 33 and the paper feeding transmission wheel 43 rotate clockwise at the same time. The one-way bearing 34 connects the separation roller 31 and the separation transmission wheel 32 together. The separation transmission wheel 33 can drive the separation roller 31 and the separation roller 32 to rotate clockwise, so that the separation roller 32 separates the top sheet of paper 6 from the material pile and transports the leading edge of the single paper 6 forward to the bottom of the paper feeding roller 42 and is clamped there. Between the paper feed roller 42 and the horizontal plate 12 of the frame, since the rotation speed of the paper feed roller 41 is greater than the rotation speed of the separation shaft 31, the paper feed roller 42 transports a single paper 6 outward; and in the process of the paper feed roller 42 rolling and transporting the paper 6, since the trailing edge of the paper 6 is still between the separation roller 31 and the loading platform 2, the moving speed of the paper 6 becomes faster under the drive of the paper feed roller 42. At this time, the inner ring and the outer ring of the one-way bearing 34 are separated, and the power transmission between the separation transmission wheel 33 and the separation roller 31 is cut off. When the rotation speed of the separation roller 31 is less than the rotation speed of the separation transmission wheel 33, the separation transmission wheel 33 can output power to the separation roller 31 again, and in the process of continuous separation and paper feeding, the separation transmission wheel 33 can rotate independently, and can also prevent the wear and impact problems caused by the instantaneous high-speed rotation of the separation roller 31 on the separation transmission wheel 33. Example 2

[0035] This embodiment provides another specific implementation of the power mechanism 5 based on the first embodiment. The technical solutions described in the first embodiment will not be repeated here.

[0036] In this example, see Figure 3, the aforementioned power mechanism 5 includes a separation roller drive motor 54 and a paper feed roller drive motor 55, the separation roller drive motor 54 and the paper feed roller drive motor 55 can be fixed to the bottom of the frame transverse plate 12 through a mounting plate, the aforementioned separation transmission wheel 33 is arranged at the right end of the aforementioned separation roller 31, and the aforementioned paper feed transmission wheel 43 is arranged at the left end of the aforementioned paper feed roller 41; the aforementioned separation roller drive motor 54 is used to drive the aforementioned separation roller assembly 3 to rotate, and includes a separation roller drive motor output shaft 541, the separation roller drive motor output shaft 541 is extended toward the right side, and a separation roller transmission belt 542 is provided on the separation roller drive motor output shaft 541. The wheel transmission belt 542 is installed on the aforementioned separation transmission wheel 33 and the separation roller drive motor output shaft 541 to realize the transmission connection between the separation roller drive motor 54 and the separation roller assembly 3; and the aforementioned paper feed roller drive motor 55 is used to drive the paper feed roller assembly 4 to rotate, and also includes a paper feed roller drive motor output shaft 551, which extends toward the left side. A paper feed roller transmission belt 552 is provided on the paper feed roller drive motor output shaft 551, and the paper feed roller transmission belt 552 is installed on the aforementioned paper feed transmission wheel 43 and the paper feed roller drive motor output shaft 551 to realize the transmission connection between the paper feed roller drive motor 55 and the paper feed roller assembly 4.

[0037] It should be noted that: the separation roller drive motor 54 and the paper feed roller drive motor 55 of the aforementioned power mechanism 5 respectively drive the separation transmission wheel 33 and the paper feed transmission wheel 43, rather than a single motor driving them simultaneously. At this time, the size relationship between the radial diameter of the aforementioned separation transmission wheel 33 and the radial diameter of the paper feed transmission wheel 43 is not limited. The drive of the separation roller drive motor 54 and the paper feed roller drive motor 55 only needs to ensure that the rotation rate of the paper feed transmission wheel 43 is greater than the rotation rate of the separation transmission wheel 33. The provision of two independent drive motors can ensure convenient maintenance. Moreover, due to the provision of the one-way bearing 34, the separation roller 31 can have a considerable rotation rate and rotate for a certain time to separate the paper even when there is no power input to the separation transmission wheel 33. The separation roller drive motor 54 only needs to maintain a relatively low power to work, which can reduce energy loss and corresponding use costs. Example 3

[0038] This embodiment provides another specific implementation of the power mechanism 5 based on the first embodiment, and the technical solutions described in the first embodiment will not be repeated here.

[0039] In this example, see Figure 3, the aforementioned paper feeding transmission wheel 43 includes a large transmission wheel portion 431 and a small transmission wheel portion 432 arranged coaxially, and the paper feeding transmission wheel 43 has a stepped structure, the aforementioned large transmission wheel portion 431 and the small transmission wheel portion 432 are both disc-shaped, the radial diameter of the aforementioned large transmission wheel portion 431 is larger than the radial diameter of the small transmission wheel portion 432, and the radial diameter of the aforementioned small transmission wheel portion 432 is smaller than the radial diameter of the aforementioned separation transmission wheel 33; and the aforementioned power mechanism 5 includes a transmission motor 56, a power belt 57 and a speed reduction belt 58, the aforementioned transmission motor 56 includes a transmission motor output shaft 561, a transmission motor output wheel 562 is installed on the transmission motor output shaft 561, the radial diameter of the transmission motor output wheel 562 is smaller than the radial diameter of the aforementioned large transmission wheel portion 431, and the aforementioned power belt 57 is sleeved between the aforementioned transmission motor output wheel 562 and the aforementioned large transmission wheel portion 4 31 and realize the transmission connection between the two, and the aforementioned speed reduction belt 58 is mounted on the aforementioned small transmission wheel portion 432 and the aforementioned separation transmission wheel 33 and realizes the transmission connection between the two, and the aforementioned transmission motor 56 can realize the differential rotation of the separation transmission wheel 33 and the paper feeding transmission wheel 43 through the power belt 57 and the speed reduction belt 58; when the transmission motor output shaft 561 of the transmission motor 56 rotates and outputs power, the transmission motor output wheel 562 rotates and drives the large transmission wheel portion 431 of the paper feeding transmission wheel 43 to rotate, and the small transmission wheel portion 432 of the paper feeding transmission wheel 43 follows and drives the separation transmission wheel 33 to rotate through the speed reduction belt 58, and because the radial diameter of the small transmission wheel portion 432 is smaller than the radial diameter of the aforementioned separation transmission wheel 33, the rotation speed of the aforementioned separation transmission wheel 33 is smaller than the rotation speed of the paper feeding transmission wheel 43, realizing two-stage deceleration, which can effectively ensure efficient and stable paper separation and transportation. Example 4

[0040] In this example, see Figure 5 , which is different from the first embodiment, the aforementioned loading platform 2 is tilted and arranged at the right rear position of the separation roller 32 of the aforementioned separation roller assembly 3, and the aforementioned frame transverse plate 12 is arranged between the separation roller 32 and the aforementioned paper feeding roller 43, and a frame top panel 15 formed between the frame side panels 11 on both sides is further provided at the upper position of the frame transverse plate 12, and a paper baffle 16 is formed at a position of the frame top panel 15 close to the aforementioned separation area 14; in this embodiment, the aforementioned The loading platform 2 is fixedly installed between the two aforementioned frame side panels 11, and the paper pile can be stacked on the loading platform 2 and one end of the paper pile can be against the paper limiting plate 16; when the paper separation and delivery operation needs to be implemented, the separation roller assembly 3 works so that the separation roller 32 separates the bottom sheet of paper from the paper pile and transports it into the space between the frame transverse plate 12 and the frame top panel 15. When the paper moves to the paper feeding roller 42, the paper feeding roller 42 can transport the single paper 6 outward.

[0041] In this embodiment, except for the above-mentioned technical features which are different from those of Example 1, other technical features are the same as those of Example 1. The power mechanism 5 also realizes transmission connection with the aforementioned separation roller assembly 3 and the paper feed roller assembly 4, and realizes differential rotation between the separation roller 31 and the paper feed roller 41.

[0042] In summary, the technical solution provided by the present invention makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the technical effect column above.
