Description

Technical Field

[0001] This application relates to the field of drawing preservation, and particularly to a winding device for artistic drawings. Background Art

[0002] For the preservation of artistic drawings, such as oil painting and Chinese ink painting drawings, in order to facilitate the preservation of the drawings, the drawings need to be wound into a cylindrical shape. In the past, the drawings were wound manually, which required a high level of proficiency during the process. Moreover, for some relatively long drawings, the winding efficiency was low. Therefore, some winding devices were designed to wind the drawings more quickly.

[0003] For example, for the drawing winding device for artistic design with the publication number CN218320044U, one side edge at one end in the length direction of the drawing is tightly pressed and fixed by two elastic plates, and then the crank is rotated to make the winding roller rotate so that the drawing is wound around the winding roller. After the winding is completed, the winding roller is removed, and then the elastic plate is pulled to remove the wound drawing from the winding roller.

[0004] Regarding the above related technology, when the width of the drawing is small, the distance between the two elastic plates is too large to simultaneously tightly press one side of the drawing, and it is difficult to effectively fix the end of the drawing with only one elastic plate, which easily leads to the situation where the winding roller rotates but the drawing cannot be driven to wind, resulting in the drawing being difficult to be effectively wound. Summary of the Invention

[0005] In order to reduce the possibility of the situation where the drawing cannot be effectively wound, this application provides a winding device for artistic drawings.

[0006] The winding device for artistic drawings provided by this application adopts the following technical solutions.

[0007] A winding device for artistic drawings includes a rotatable winding cylinder. An axial opening for placing one side edge of the drawing is formed on the circumferential outer wall of the winding cylinder along its axial direction. A pressing strip that can slide into the axial opening to abut against the drawing is slidably connected inside the winding cylinder. A control slider that can make the pressing strip enter or exit the axial opening is slidably connected inside the winding cylinder.

[0008] By adopting the above technical solutions, when the width of the drawing is small, the pressing strip can also fully press one side of the drawing in the axial opening, so that during the rotation of the winding cylinder, the drawing can effectively follow the rotation of the winding cylinder for winding work.

[0009] Optionally, a passive wedge block is fixedly connected to the pressing strip, and an active wedge block that can abut against the passive wedge block is fixedly connected to the control slider. The moving direction of the control slider is along the axis direction of the winding cylinder. When the control slider moves towards the center point of the winding cylinder, the active wedge block will push the passive wedge block towards the pressing strip side to move.

[0010] By adopting the above technical solution, as long as the control slider is pressed, the drawing located on one side of the axial opening will be fixed.

[0011] Optionally, there is a support on one side of the winding drum. The support is rotatably connected to a seat rotating shaft. The winding drum is coaxially and detachably connected to the seat rotating shaft. The seat rotating shaft is provided with a shaft convex block that can abut against the control slider so that the pressing strip enters the axial opening and abuts against the drawing.

[0012] By adopting the above technical solution, as long as the winding drum is connected and installed corresponding to the seat rotating shaft, the pressing strip will extend into the axial opening to tightly press and fix the drawing, which is relatively convenient for fixing the drawing.

[0013] Optionally, the shaft convex block is slidably connected to the seat rotating shaft along the axis direction of the seat rotating shaft. The shaft convex block is fixedly connected with a dial block exposed outside the seat rotating shaft.

[0014] By adopting the above technical solution, when it is necessary to remove the drawing from the winding drum, it is not necessary to disassemble the winding drum from the seat rotating shaft. Only by pulling the dial block can the pressing strip not tightly press the drawing.

[0015] Optionally, a strong compression spring that forces the shaft convex block to move towards the control slider is provided inside the seat rotating shaft.

[0016] By adopting the above technical solution, to ensure that during the winding process, the pressing strip can abut against the drawing, so that the drawing can be stably and effectively wound.

[0017] Optionally, a weak compression spring that forces the passive wedge block to move towards the active wedge block so that the pressing strip moves out of the axial opening is provided inside the winding drum. The elastic modulus of the weak compression spring is less than that of the strong compression spring.

[0018] By adopting the above technical solution, when it is necessary for the pressing strip to be away from the drawing, the pressing strip is not likely to come into contact with the drawing again, so as to reduce the scratching of the drawing surface by the pressing strip.

[0019] Optionally, the support is rotatably connected with a kit that can sleeve the dial block inside so that the dial block remains away from the winding drum.

[0020] By adopting the above technical solution, when it is necessary to remove the wound drawing from the winding drum, it is not necessary to keep pulling the dial block all the time, so as to conveniently remove the drawing from the winding drum.

[0021] Optionally, a magnet that can adsorb the kit is fixedly connected to the support at a position away from the dial block on the side of the rotation point of the kit.

[0022] By adopting the above technical solution, the kit is not easily rotated when not in use.

[0023] Optionally, a seat slider is slidably connected to the support, and a flattening roller is rotatably connected to the seat slider. The flattening roller can be attached to the surface of the part of the drawing wound around the winding drum. A flattening spring that forces the seat slider to move toward the winding drum is detachably connected to the support.

[0024] By adopting the above technical solution, the wound drawing can be made more compact, so that after the drawing is taken off the winding drum, there is no need for manual compact winding treatment of the drawing.

[0025] Optionally, the axial opening is arc-shaped, and the end face of the pressing strip extending into the axial opening is arc-shaped.

[0026] By adopting the above technical solution, one end of the drawing entering the axial opening is not easily bent greatly during the winding process, so that after the drawing is unfolded subsequently, it is easier to flatten the side of the drawing entering the axial opening. Moreover, the pressing strip can also adaptively fit the surface of the drawing with a large area, so that the drawing is not easily separated from the axial opening during the winding process.

[0027] In summary, the present application has at least the following beneficial effects.

[0028] 1. When the width of the drawing is small, the pressing strip can also fully press one side of the drawing into the axial opening, so that during the rotation of the winding drum, the drawing can effectively rotate with the winding drum for winding work;

[0029] 2. The fixing and taking-out methods of the drawing in the axial opening are both relatively convenient;

[0030] 3. It is more difficult for the drawing to have large and irrecoverable bends on one side in the axial opening. Description of the Drawings

Detailed Embodiments

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] An embodiment of the present application discloses an art drawing reel. Referring to Figure 1 , it includes a support 43. A seat rotating shaft 44 with a horizontal rotation axis is rotatably connected to the support 43. The support 43 can be provided with a motor or a hand crank to drive the seat rotating shaft 44 to rotate. One end of the seat rotating shaft 44 is coaxially and detachably connected to a winding drum 1. An axial opening 2 is formed on the circumferential surface of the winding drum 1 along the direction of its own axis. One side of one end of the drawing in the length direction is placed into the axial opening 2 and fastened, so that the rotation of the winding drum 1 can wind the drawing. Moreover, a shaft rod can be slidably arranged on the support 43 and inserted into one end of the winding drum 1 far from the seat rotating shaft 44 to provide a certain support for the winding drum 1 during the winding process.

[0037] Referring to Figure 1 , the axial opening 2 penetrates through one end face of the winding drum 1 far from the seat rotating shaft 44, so as to remove the drawing from the winding drum 1 after the drawing is wound. The opening shape of the axial opening 2 on the end face of the winding drum 1 is arc-shaped. The rotation direction of the winding drum 1 conforms to the opening direction of the axial opening 2 from the circumferential outer wall to the inside of the winding drum 1, so that the wound drawing is not likely to produce a difficult-to-recover bend at one side inside the axial opening 2.

[0038] Referring to Figure 2 , a pressing strip 3 that can enter the axial opening 2 to press the drawing against the inner wall of the axial opening 2 is slidably connected inside the winding drum 1. One end of the pressing strip 3 in contact with the drawing can be a rubber strip, and the end face of the pressing strip 3 in contact with one end of the drawing is arc-shaped. The length direction of the pressing strip 3 is consistent with the axis direction of the winding drum 1, and the length of the pressing strip 3 is close to the length of the winding drum 1, so that the pressing strip 3 can tightly press and fix the drawing in a large range. One end of the pressing strip 3 located inside the winding drum 1 is fixedly connected to a passive wedge block 41. An active wedge block 42 with an inclined surface that can abut against the inclined surface of the passive wedge block 41 is slidably connected inside the winding drum 1. The moving direction of the active wedge block 42 is consistent with the axis direction of the winding drum 1. A control slider 4 fixedly connected to the active wedge block 42 is slidably connected at one end of the winding drum 1 close to the seat rotating shaft 44. When the control slider 4 moves towards the center point side of the winding drum 1, the active wedge block 42 will push the passive wedge block 41 to move, so that the pressing strip 3 can enter the axial opening 2 to tightly press the drawing.

[0039] Referring to Figure 2 and Figure 3, a shaft convex block 46 is slidably connected to the end face of the seat rotating shaft 44 close to the winding drum 1. The sliding direction of the shaft convex block 46 is consistent with the axis direction of the seat rotating shaft 44. The shaft convex block 46 can abut against the control slider 4. A strong compression spring 48 that can force the shaft convex block 46 to move towards the control slider 4 is placed in the seat rotating shaft 44. The shaft convex block 46 is fixedly connected to a dial block 47 exposed on the circumferential outer wall of the seat rotating shaft 44. When the drawing winding is completed, by pulling the dial block 47, the active wedge block 42 can be made to no longer tightly press against the passive wedge block 41. Moreover, a weak compression spring 49 that forces the passive wedge block 41 to move away from the axial port 2 is detachably connected inside the winding drum 1. After the dial block 47 is pulled, the passive wedge block 41 can be pushed by the weak compression spring 49 so that the pressing strip 3 moves away from the side of the drawing located inside the axial port 2. And, the elastic modulus of the weak compression spring 49 is less than that of the strong compression spring 48, so that the force exerted by the strong compression spring 48 on the shaft convex block 46 is sufficient to compress the weak compression spring 49, so that the pressing strip 3 can tightly press against the drawing.

[0040] Refer to Figure 1 , a kit 31 is rotatably connected to the upper part of the support 43. The kit 31 can be formed by bending a rod. One end of the kit 31 away from its rotation point can be sleeved on the dial block 47 that is pulled away from the winding drum 1, so that the dial block 47 cannot easily reset, so as to remove the drawing from the winding drum 1. A magnet 35 that can adsorb the kit 31 is fixedly connected to the upper part of the support 43 on the side away from the dial block 47 at the rotation point of the kit 31, so that during the drawing winding process, the kit 31 does not easily rotate.

[0041] Refer to Figure 1 , a seat slider 32 is slidably connected to the support 43 in the vertical direction. The seat slider 32 is rotatably connected to a flattening roller 33 located directly below the winding drum 1. The axis direction of the flattening roller 33 is consistent with the axis direction of the winding drum 1. The support 43 is detachably connected to a flattening spring 34 that forces the seat slider 32 to move upward, so that during the drawing winding process, the flattening roller 33 can tightly press the drawing against the winding drum 1, so that the wound drawing is relatively compact. Moreover, the surface of the winding drum 1 can be made of a material with a relatively high self-lubrication coefficient, such as polytetrafluoroethylene and graphene, etc., so that when the relatively compact drawing is to be removed from the winding drum 1, the drawing can be removed more smoothly and the wear is not likely to be large.

[0042] The implementation principle of a kind of art drawing winder in the embodiment of the present application is as follows: Pull the dial block 47, rotate the kit 31 and sleeved it on the dial block 47, then put one end of the drawing in the length direction into the axial port 2, and then reset the kit 31 so that the dial block 47 can be reset, that is, make the pressing strip 3 enter into the axial port 2 to press and fix the drawing, and then rotate the seat rotating shaft 44 to wind the drawing. After the winding is completed, pull the dial block 47, rotate the kit 31 and sleeved it on the dial block 47, move the drawing along the axis direction of the winding cylinder 1 and away from the seat rotating shaft 44, so as to take down the wound drawing for binding or put it into the corresponding storage cylinder for storage.

[0043] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
