Description

Technical Field

[0001] The present invention relates to the technical field of winding-related technology, and in particular to a high-speed non-stop winding storage device based on double limiting and a storage method thereof. Background Art

[0002] Printing is the technology of batch copying the contents of original manuscripts such as text, pictures, photos, anti-counterfeiting, etc. through plate making, inking, pressurization and other processes, so as to transfer ink to the surface of materials such as paper, textiles, plastics, leather, PVC and PC. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. There are many types of substrates, including paper, cloth and banners. When printing cloth or banners, the printed cloth and banners need to be rolled.

[0003] In order to improve the winding efficiency and make the printing machine work continuously, there are various non-stop roll changing mechanisms available, that is, the winding roller is replaced while the printing machine is working continuously. The existing non-stop roll changing mechanism adopts flying knife cutting and then mechanical traction to the newly replaced winding roller for winding operation. Mechanical traction to the winding roller can easily cause wrinkles on the front end of the material, resulting in material waste. Especially when winding higher-value materials, the above-mentioned non-stop roll changing mechanism is not very suitable. Therefore, when winding higher-value materials, manual cutting is generally adopted and then manual laying is carried out on the newly replaced winding roller. In this way, there is a situation where the printing machine cannot work continuously. Summary of the invention

DETAILED DESCRIPTION

[0020] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0021] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0022] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0023] See also Figure 1-Figure 4 In the embodiment of the present invention, a high-speed non-stop winding and storage device based on double limit comprises: a frame 1, comprising two side plates, and a accommodating space is formed between the two side plates; a fixed storage rack 2, which is provided with two and is installed on a receiving rack 6 fixed to the two side plates, and a plurality of first guide rollers 17 are rotatably installed between the two fixed storage racks 2, and preferably, the plurality of first guide rollers 17 are equidistantly arranged along the length direction of the fixed storage racks 2; two movable storage racks 9 are provided and fixed by a connecting rod, and the movable storage rack 9 is slidably installed on the frame 1 and connected to a vertical driving member installed on the frame 1. Then, a plurality of second guide rollers 18 are rotatably installed between the two movable material storage racks 9. Preferably, the plurality of second guide rollers 18 are equidistantly arranged along the length direction of the movable material storage rack 9; a clamping mechanism is installed on the frame 1; materials (including but not limited to printed films) alternately bypass the plurality of first guide rollers 17 and the plurality of second guide rollers 18 and are wound up by the winding roller through the clamping mechanism, and when the winding roller performs the winding action, the movable material storage rack 9 is at the upper end of the frame 1, and when the winding roller is replaced, the clamping mechanism performs the clamping action, and the vertical drive member drives the movable material storage rack 9 to perform the downward movement action.

[0024] In this embodiment, the material is fixed from one side of the frame 1 by a clamping mechanism so that the end of the material on the side being wound will not be displaced. At this time, the printing press remains in a continuous working state, and the vertical driving member drives the movable material storage rack 9 to move downward, so that the material printed by the printing press is buffered between the multiple first guide rollers 17 and the multiple second guide rollers 18, providing time for the subsequent replacement of the winding rollers, keeping the printing press running without stopping, and improving work efficiency.

[0025] It should be noted that, since the material alternately bypasses the multiple first guide rollers 17 and the multiple second guide rollers 18, when the distance between the multiple first guide rollers 17 and the multiple second guide rollers 18 changes, the material retention between the fixed storage rack 2 and the movable storage rack 9 gradually increases, thereby achieving the purpose of material caching.

[0026] For further information, see Figure 1 and Figure 2The pressing mechanism includes a rotating roller 7 rotatably mounted on the frame 1 and a pressing member capable of abutting against or separating from the rotating roller 7. The material passes between the rotating roller 7 and the pressing member, and the material is fixed when the pressing member abuts against the rotating roller 7.

[0027] Exemplarily, in one embodiment, the clamping member includes a clamping roller 8, both ends of which are rotatably mounted with adjustment units, the adjustment unit includes a movable plate 14 rotatably connected to the frame 1, one end of the movable plate 14 is rotatably connected to the clamping roller 8, and the other end is hinged to a cylinder 13 rotatably mounted on the frame 1.

[0028] When the winding roller is normally winding, the cylinder 13 is in a retracted state. At this time, the pressure roller 8 and the rotating roller 7 are in a separated state, so the material will not be hindered when passing through the rotating roller 7. When the winding roller needs to be replaced, the cylinder 13 extends to drive the movable plate 14 to rotate. When the movable plate 14 rotates, it drives the pressure roller 8 to rotate toward the rotating roller 7, so that the pressure roller 8 and the rotating roller 7 are in abutment state to clamp the material to prevent the material from losing traction and becoming loose after being cut at the winding roller. At the same time, it can ensure that when the distance between the fixed storage rack 2 and the movable storage rack 9 increases, the material coming out of the printing press can be cached and the material can be kept in a tensioned state.

[0029] Preferably, the outer side of the pressing roller 8 is covered with a rubber sleeve, so as to increase the friction between the material and the pressing roller 8 and effectively protect the material to a certain extent.

[0030] Among them, at least one sliding block 11 is fixed on the movable material storage rack 9, and the sliding block 11 is slidably connected to a slide rail 12 fixed on the frame 1, so as to ensure the stable up and down movement of the movable material storage rack 9.

[0031] Furthermore, the vertical driving member includes at least one ball screw 10 rotatably mounted on the frame 1 and a threaded movable member 19 threadedly connected to the ball screw 10, and the threaded movable member 19 is fixedly connected to the movable storage rack 9; one end of the ball screw 10 is connected to a driving source mounted on the frame 1.

[0032] See also Figure 1 and Figure 2In this embodiment, two ball screws 10 are installed on a side plate, and the driving source includes a motor (not shown in the figure) installed on one of the side plates. The output shaft of the motor is connected to two reducers 4 through a transmission member. A transmission shaft 3 is fixed to the output end of the reducer 4. The transmission shaft 3 is rotatably connected to the ball screw 10 through a bevel gear set 5. When the motor is working, it drives the two reducers 4 to move through the transmission member. The reducer 4 drives the transmission shaft 3 to rotate. When the transmission shaft 3 rotates, the ball screw 10 is driven to rotate through the bevel gear set 5. When the ball screw 10 rotates, it cooperates with the threaded movable member 19 to drive the movable storage rack 9 to rise or fall, thereby realizing the driving requirements.

[0033] Preferably, travel switches 15 are symmetrically installed on the frame 1 at both ends along the moving direction of the movable storage rack 9, and the travel switches 15 establish communication with the driving source. The two travel switches 15 are used to control the up and down movement distance of the movable storage rack 9 to realize the travel control of the movable storage rack 9. The travel switches 15 are the application of existing components, so they will not be described in detail in this embodiment.

[0034] Furthermore, limit members 16 are symmetrically installed on both ends of the frame 1 along the moving direction of the movable storage rack 9, and the distance between the two limit members 16 is greater than the distance between the two travel switches 15. The limit member 16 includes a limit rod fixed on the frame 1 and a rubber ring installed on the limit rod. When the travel switch 15 fails, the limit member 16 can effectively limit the movement range of the movable storage rack 9 to prevent the material from loosening or being pulled apart, thereby achieving double limit.

[0035] As another embodiment of the present invention, a high-speed non-stop winding and storage method based on double limit is also proposed. The high-speed non-stop winding and storage device based on double limit is adopted, which includes the following steps: when the winding roller performs the winding action, the movable storage rack 9 is initially at the uppermost end of the frame 1. When the winding roller needs to be replaced, the clamping mechanism will clamp and fix the material, and the movable storage rack 9 moves downward under the action of the vertical drive member, so that the material is cached between the movable storage rack 9 and the fixed storage rack 2; after the winding roller is replaced, the winding roller accelerates the winding speed, and the movable storage rack 9 moves upward under the action of the vertical drive member. When the movable storage rack 9 moves to the uppermost end, the winding speed of the winding roller slows down and maintains a uniform winding speed.

[0036] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
