Description

Technical Field

[0001] The invention belongs to the field of paper pulling devices for calligraphy, and in particular relates to a friction paper pulling machine special for calligraphy and a control method thereof. Background Art

[0002] The calligraphy and painting table in the prior art is a common table top with a piece of felt spread on it, and then calligraphy and painting paper is placed on the felt for writing or painting. When faced with a long calligraphy paper, a person or the writer must pull the paper manually on a commonly used small or large table top, otherwise the paper cannot be completely spread on the table top, resulting in the need to constantly move the position of the paper when writing on it, which makes the writing process of one person more troublesome.

[0003] Chinese patent publication number CN113425081A discloses a calligraphy writing table for Chinese language teaching, comprising a table body having a work surface, a groove formed on one side of the work surface, a roller rotatably connected within the groove, and a paper pulling mechanism on the other side of the work surface, the paper pulling mechanism comprising a bracket and a rotating shaft disposed on the bracket. The present invention has the following advantages and effects: a foot switch is connected between a first motor and a power switch, and the foot switch controls the first motor and the power switch to open and close. When the long paper roll needs to be moved, the student only needs to lightly step on the foot switch, which turns on the first motor, which drives the rotating shaft to rotate clockwise, causing a pull cord to wrap around the surface of the rotating shaft. The pull cord pulls the clamping mechanism, thereby pulling the long paper roll. When the long paper roll does not need to be moved, the foot switch can be released, thereby preventing the student from constantly moving the paper during writing, which affects writing efficiency.

[0004] However, the writing table described in the above-mentioned comparative document is relatively large, and the device is installed integrally with the entire desk, resulting in poor portability. In addition, when the paper is pulled, the paper is rolled up, which makes it inconvenient for the writer to view the previous content. In addition, if the writing is done in a vertical manner, after completing the writing on one side, the scroll needs to be reversed and writing needs to be done again, which makes the writing process more troublesome. Moreover, the size of the writing paper on this desktop is limited by the size of the desktop, and cannot be used for extra-large rice paper or rice paper that exceeds the size of the desktop and the width of the roll.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a friction paper pulling machine special for calligraphy and a control method thereof.

[0007] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0013] A control method for a friction paper pulling machine for calligraphy, applicable to any of the above-mentioned friction paper pulling machines for calligraphy, comprising:

[0014] Driving module: used to drive the rotating roller to rotate forward or reverse and the speed of the rotating roller;

[0015] Receiving module: When the driving module is in power-on mode and the voltage is connected, it outputs the receiving signal;

[0016] Remote control module: includes an output module. When operating, pressing different buttons on the remote control module outputs different signal instructions to the receiving module through the output module to control the driving module to operate the rotating roller.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0018] 1. When using the friction paper pulling machine for calligraphy and its control method, the written paper is placed between the base and the rotating roller. The protective frame itself has the function of a ruler. By turning on the reduction motor to drive the rotating roller on one side of the rotating disk to rotate, the friction sleeve on the peripheral side of the rotating roller contacts the surface of the paper. The bottom of the paper is located on the smooth surface of the base. The friction force between the friction sleeve and the paper is greater than the friction force between the paper and the smooth surface, so that the paper can be pushed. By pushing the squeezing block, one side of the squeezing block abuts against the oblique side of the trapezoidal groove, so that the lifting block drives the rotating roller to move upward, so that the rotating roller is separated from the paper, which is convenient for taking out the paper. The device can be placed on different writing surfaces (including desktops), and is pulled at the side of the paper. The paper size is not restricted, making it convenient for pulling paper in different directions for writing on large-scale central halls or long scrolls and other different formats of calligraphy works. The device is small, light and easy to carry, making it convenient to carry and place on desktops of different sizes for use. The laser marking function is provided by the laser marking device installed on the protective frame during the paper pushing process. The device can be placed on different desktops or any horizontal writing plane (including the ground) for use. The device can also be used to drag and unfold cloth and the like of different materials.

[0019] 2. The calligraphy-specific friction paper pulling machine and its control method are configured such that a first spring is installed on the lifting block so that the rotating roller can press the paper below, thereby facilitating the pushing of the paper. When the paper needs to be taken out, the rotating roller and the rotating disk are connected by the first clamping block and the first L-shaped groove, thereby facilitating the removal of the rotating roller. The rotating rollers of different lengths can be replaced according to the different sizes of paper.

[0020] 3. When the friction paper puller of the present invention is used for rice paper with good toughness or other writing materials with high toughness, the user can directly pull the writing material, pull the writing material out through the friction paper puller, and continue to write repeatedly, thereby improving the portability of the paper puller for the user. A screw can also be provided on the upper side of the vertical block. The screw thread is engaged with the vertical block and one end passes through the vertical block and cooperates with the first spring. This makes it convenient for the user to achieve the effect of squeezing the first spring by rotating the screw, thereby controlling the adjustment of the friction force between the rotating roller and the paper.

[0021] 4. The above-mentioned comparative document uses a reel fixed on the side of a table to wind the paper at one end, which will cause the wound end of the paper to curl up, and the written effect of the wound part cannot be seen intuitively, which will affect the writing effect. The present invention only moves the paper by friction, so that the paper is in a flat state. When the friction between the paper and the felt is small, and the felt and the paper are relatively smooth, the base only needs to support the opposing block and does not need to be laid on the bottom of the paper.

When the paper needs to be taken out, Figure 8 and 9 As shown: by pushing the squeezing block 6, one side of the squeezing block 6 abuts against the oblique side of the trapezoidal groove 304, so that the lifting block 3 drives the rotating roller 4 to move upward, so that the rotating roller 4 is separated from the paper, which is convenient for taking out the paper. At this time, the fixed block 603 on the squeezing block 6 is located in the fixed groove 207 to fix the squeezing block 6. By pulling the shift block 604 to drive the fixed block 603 to move upward and out of the fixed groove 207, the fixation of the squeezing block 6 can be released, so that the lifting block 3 drives the rotating roller 4 to press the paper through the force of the first spring 303.

[0043] A control method for a friction paper pulling machine for calligraphy, applicable to the friction paper pulling machine for calligraphy described in any of the above embodiments, comprising:

[0044] Driving module: used to drive the rotating roller 4 to rotate forward or reverse and the speed of the rotating roller 4;

[0045] Receiving module: When the driving module is in power-on mode and the voltage is connected, it outputs the receiving signal;

[0046] Remote control module: includes an output module. When operating, pressing different buttons on the remote control module outputs different signal instructions to the receiving module through the output module to control the driving module to operate the rotating roller 4.

[0047] In the control method of the friction paper pulling machine of this embodiment, the connection mode between the receiving module and the output module can be a wired / WIFI / Bluetooth connection mode, and the control button on the remote control module is used to control the start and stop of the reduction motor 7, thereby driving the rotating roller to rotate. The control button on the remote control module can also be used to control the opening and closing of the laser scriber 21, so that the writer can observe the angle between the paper and the protective frame 5 to determine the verticality of the paper and facilitate the adjustment of the paper.

[0048] The base 1 of this embodiment is generally thinner at the contact portion with the rotating roller 4, with a thickness of 0.5-2 mm. The base 1 has a smooth surface and arc chamfers on the sides to reduce friction between the base 1 and the paper.

[0049] Example 2: This example differs from Example 1 in that the engaging assembly includes a slot on the outer edge of the rotating roller 4 and a keyway on the connecting rod 801. The keyway communicates with the slot and contains a key block. While this example 2 reduces production costs and margins compared to Example 1, the separate key block poses a risk of loss or loosening.

[0050] Example 3: The difference between Example 3 and Example 1 is that the lifting component includes a magnet arranged at the bottom of the lifting block 3 and at one side of the pressing plate 6. The relative surfaces of the two magnets repel each other magnetically, and the pressing plate 6 slides inside the vertical block 2. When the pressing plate 6 is pushed to the bottom of the lifting block 3, the magnet on one side of the pressing plate 6 is close to the magnet at the bottom of the lifting block 3, and the lifting block 3 is driven to rise by magnetic force, so that a gap is generated between the rotating roller 4 and the smooth surface 103, so that the paper can be taken out.

[0051] Embodiment 4: This embodiment 4 can select any one or more of the above embodiments 1-3, and proposes three uses of the friction paper pulling machine for calligraphy, as follows:

[0052] Example 4.1: This embodiment has one friction paper pulling machine. By rotating the roller 4, it can cooperate with the smooth surface 103 to drive the paper to move. However, when facing wider paper, the balance is poor and there is a certain limitation on the width of the paper.

[0053] Example 4.2: In this embodiment, there are two friction paper stretchers, which are symmetrically arranged and can move both sides of the paper simultaneously and synchronously, so that it can be suitable for paper of different widths or larger widths.

[0054] Example 4.3. In this embodiment, there are two friction paper pullers, which are arranged one in front and one in the back. The friction paper puller at the front end can drive the paper to move and pass through the protective frame 5, which has the function of a ruler. The friction paper puller at the rear end can replace the rotating roller 4 with a rotating roller that can roll up the paper, so that in the process of pulling the paper, the written paper can also be rolled up.

[0055] The rotating roller 4 proposed in the present invention rotates to rub the paper, thereby achieving the effect of pulling the paper to move (this method is only one of the methods of the present invention, and other methods can also be used to rub the paper to achieve the effect of paper movement).

[0056] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention, which have the same or similar technical solutions as the present invention, should be understood to fall within the scope of protection of the present invention. The technologies, shapes, and structural parts not described in detail in the present invention are all well-known technologies.
