DETAILED DESCRIPTION

[0019] The present application will be further described in detail below in combination with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0020] For the purpose of clarity, only the parts of the apparatus that are pertinent to the invention are shown in the drawings, and they do not necessarily show the actual configuration of the product. In addition, in some of the drawings, only one of the components with the same structure or function is shown schematically, or only one of them is labeled, in order to make the drawings simple and easy to understand. In this document, "one" means not only "only one", but also "more than one", and "several" includes "two" and "more than two".

[0021] In this document, unless otherwise explicitly specified and limited, the terms "mount", "connect", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.

[0022] In the present invention, unless otherwise explicitly specified and limited, "on" or "under" of the first feature to the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, "on", "above" and "over" of the first feature to the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the first feature is higher than the second feature in horizontal height.

[0024] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] As Figures 1-8As shown, it shows a floor cloth storage device in an embodiment of the present application, including a cloth laying platform 100, an upper winding lifting platform 200, and a lower winding lifting platform 300. The cloth laying platform 100 has several layers of belt conveying assemblies 110 for laying floor cloth, and each layer of belt conveying assembly 110 can be expanded to prevent a roll of floor cloth from being placed. The belt of the belt conveying assembly 110 is provided with a plurality of ventilation holes 111, and a plurality of ventilation pipes 120 are arranged on the cloth laying platform 100. The ventilation pipes 120 can be inserted between the upper and lower layers of the annular belt from the direction of the power shaft axis of the belt conveying assembly 110 and can be blown, and correspondingly, in addition to the entrance of the ventilation pipe 120, the side of the belt conveying assembly 110 should be sealed as much as possible to reduce the amount of gas leakage, thereby increasing the amount of gas blown to the floor cloth through the ventilation hole. The way of blowing air through the ventilation hole on the belt can increase the ventilation amount of the floor cloth placed on the belt, and avoid the problem of poor airing effect of the floor cloth on one side of the floor cloth.

[0026] The upper winding lifting platform 200 is arranged at one end of the cloth laying platform 100 and is provided with a winding assembly 210, a leveling assembly 220 and a traction conveying assembly 230. The upper winding lifting platform 200 can be lifted by a lead screw assembly. The winding assembly 210 is used to place a roll of floor cloth, and the traction conveying assembly 230 draws the floor cloth from the winding assembly 210, so that it passes through the leveling assembly 220 and is then conveyed to the belt conveying assembly 110 of the cloth laying platform 100. The upper winding lifting platform 200 can lift itself to make the traction conveying assembly 230 convey the floor cloth to the belt conveying assembly 110 of different layers. The winding assembly 210, the leveling assembly 220 and the traction conveying assembly 230 can all use existing technology. Alternatively, the winding assembly 210 includes a winding air expansion shaft with a magnetic powder clutch, and the winding air expansion shaft can fix the roll of floor cloth. The traction conveying assembly can be composed of upper and lower rollers, one of which is a power roller connected to a driving device, and the other can press the floor cloth passing between the two rollers towards the power roller to traction convey the floor cloth by friction.

[0027] A leveling component 220 is provided between the traction conveyor assembly 230 and the unwinding assembly 210. The leveling component 220 can level the flooring fabric by pressing it with multiple vertically spaced compression rollers, or it can flatten the flooring fabric by winding it vertically in the opposite direction of curling. After leveling the flooring fabric, the leveling component 220 moves it towards the belt conveyor assembly 110 via the traction conveyor assembly 230. To ensure a smooth transition of the flooring fabric, a transition plate is also provided between the traction conveyor assembly 230 and the belt conveyor assembly 110. The transition plate acts as a support, and its height should be higher than the upper surface of the corresponding belt conveyor assembly 110 when conveying the flooring fabric onto the belt conveyor assembly 110, allowing for a smooth transition. Once the flooring fabric enters the belt conveyor assembly 110, the belt conveyor assembly 110 can convey the flooring fabric forward via a belt. The conveying speed of the belt conveyor assembly 110 should be greater than the conveying speed of the traction conveyor assembly 230 to maintain a certain tension on the flooring fabric.

[0028] The lower lifting platform 300 is positioned at the other end of the fabric laying platform 100, and a winding assembly 310 is mounted on it to collect the dried floor fabric. The lower lifting platform 300 is also raised and lowered via a screw assembly, allowing the winding assembly 310 to collect floor fabric from different layers of the belt conveyor assembly 110, and the belt conveyor assembly 110 to transport the floor fabric to a position close to the lower lifting platform 300. The winding assembly 310 includes a feeding guide table 311, a winding air shaft 312, and a pushing mechanism 313. The feeding guide table 311 is located on the lower lifting platform 300, conforming to the discharge end of the belt conveyor assembly 110, and gradually decreasing in height away from the belt conveyor assembly 110, guiding the floor fabric into subsequent processes. The winding air shaft 312 is rotatably mounted on the lower lifting platform 300, located on the side of the feeding guide table 311 away from the belt conveyor assembly 110, and is used to fix the winding drum. The pushing mechanism 313 is located on the lower lifting platform 300, below the take-up air shaft 312 and engaged with the unloading guide table 311. Under the push of the belt conveyor assembly 110, it pushes the floor cloth coming from the unloading guide table 311 toward the take-up drum on the take-up air shaft 312, so that the adhesive on the take-up drum can bond the floor cloth, thereby allowing the floor cloth to rotate with the take-up drum.

[0029] The jacking mechanism 313 consists of a lifting frame 3131, a push plate 3132, a pressure box 3134, and a jacking elastic element 3135. The lifting frame 3131 is jacked up and down on the lower winding lifting platform 300 and positioned below the winding air shaft 312. The push plate 3132 is spaced apart on the lifting frame 3131, has several connecting holes 3133, and is connected to the unloading guide table 311. The floor is arranged on the push plate 3132. The pressure box 3134 is located at the bottom of the push plate 3132 and is connected to an air pump and the connecting holes 3133. Under the action of the air pump, a positive pressure chamber or a negative pressure chamber can be formed to assist in jacking the floor. The pressure box 3134 is connected to the lifting frame 3131 through the jacking elastic element 3135, which provides an upward force to the pressure box 3134.

[0030] The bottom of the pressure box 3134 and the top of the lifting frame 3131 are fixed with push elastic elements 3135 by hooks or welding. The push elastic elements 3135 can be compression springs. When the lifting frame 3131 rises and pushes the floor cloth towards the take-up drum on the take-up air shaft 312 via the push plate 3132, to prevent the floor cloth from slipping off the push plate 3132 under gravity, a negative pressure is created in the pressure box 3134 by an air pump, so that the push plate 3132 can hold the floor cloth through the connecting hole 3133. After the floor cloth is pushed onto the take-up drum, the take-up drum is wound up by the take-up air shaft 312. At this time, as the amount of floor cloth on the take-up drum increases, the distance between the outermost edge of the floor cloth and the axis of the take-up drum gradually increases, thereby exerting a squeezing effect on the push plate 3132, and the push elastic element 3135 is compressed.

[0031] The push elastic element 3135 can not only prevent the push plate 3132 from colliding hard with the winding drum, but also squeeze the floor cloth on the winding drum through the push plate 3132 to avoid gaps during the winding process, thereby improving the winding quality.

[0032] Furthermore, the take-up air shaft 312 is driven to rotate by a drive device. The take-up speed of the take-up air shaft 312 should be greater than the conveying speed of the belt conveyor assembly 110, so as to use the friction between the floor cloth and the belt conveyor assembly 110 to tension the floor cloth.

[0033] The lower winding lifting platform 300 is also equipped with a fabric pushing mechanism 320, which consists of a swing rod 321, a rotating push roller 322, a swing top rod 323, and a reset elastic element 324. The swing rod 321 is oscillating on the lifting frame 3131 via a pin on the side of the winding air shaft 312 away from the belt conveyor assembly 110, and can swing closer to the winding air shaft 312. The rotating push roller 322 is rotatably mounted on the swing rod 321 via a bearing. When the swing rod 321 swings, it drives the rotating push roller 322 to push the floor cloth on the push plate 3132 to adhere to the winding drum on the winding air shaft 312, so that the floor cloth entering the push plate 3132 can be completely adhered to the winding drum.

[0034] The swinging top rod 323 is pivotally mounted at the end of the swing rod 321 away from the swing axis via a pin, and its swing axis is parallel to the swing rod 321. The rotating push roller 322 is pivotally mounted at the end of the swinging top rod 323 away from the swing axis. The two ends of the return elastic element 324 act on the swinging top rod 323 and the swing rod 321 respectively, allowing the swinging top rod 323 to swing to be parallel to the swing rod 321. The return elastic element 324 can be a coil spring, and it is connected to the swinging top rod 323 and the swing rod 321 by hooks or welding.

[0035] By using the swing rod 323 and the reset elastic element 324, the rotating push roller 322, driven by the swing rod 321, pushes the flooring fabric closer to the winding drum, ensuring that the rotating push roller 322 remains in contact with the arc surface of the winding drum. Furthermore, during the winding process, the swing rod 323 compresses the reset elastic element 324 to accommodate the increase in the winding diameter of the flooring fabric. The elastic force of the reset elastic element 324 also ensures that the rotating push roller 322 remains in contact with the flooring fabric on the winding drum, effectively preventing gaps from forming during winding.

[0036] Furthermore, by rotating the push roller 322, the friction between it and the flooring fabric can be reduced, thereby preventing the flooring fabric from being damaged by friction. The friction between the push plate 3132 and the flooring fabric can be reduced by changing the pressure box 3134 to a positive pressure state, with gas being blown out from the connecting hole 3133, thereby further squeezing the push elastic element 3135 through air pressure, thus reducing the friction between the push plate 3132 and the flooring fabric.

[0037] The push plate 3132 and the air pressure box 3134 have a vertically penetrating clearance groove 3136. The swing rod 321 can swing in the groove. When the swing rod 321 is horizontal, the axis of the rotating push roller 322 is in the same vertical plane as the axis of the winding air expansion shaft 312. This allows the push plate 3132 to adhere the floor cloth to the bottom of the winding drum through the lifting frame 3131. Then, the rotating push roller 322 can be driven by the swing rod 321 to gradually push the floor cloth upward from the bottom of the winding drum to adhere to the winding drum.

[0038] Furthermore, to ensure that the flooring fabric remains as flat as possible during the pushing process by the rotating push roller 322, multiple sets of pushing mechanisms 320 can be set along the axial direction of the take-up air shaft 312, and the multiple sets of pushing mechanisms 320 act synchronously. At the same time, when the pushing mechanism 320 performs the pushing action, the air pressure box 3134 should maintain a negative pressure state, so as to ensure that the part of the flooring fabric that is not attached to the take-up drum is always subjected to a downward suction force. This not only improves the extensibility of the flooring fabric, but also prevents the flooring fabric from attaching to the take-up drum before being pushed onto it by the rotating push roller 322, thus affecting the take-up quality.

[0039] Furthermore, when the swing rod 321 is horizontal, the highest point of the outer wall of the rotating push roller 322 should not be higher than the upper surface of the push plate 3132, so as to avoid the rotating push roller 322 affecting the extension of the floor cloth on the push plate 3132.

[0040] Optionally, the swing of the swing rod 321 is achieved by a linear drive device 400. One end of the linear drive device 400 is oscillating on the lifting frame 3131 via a pin, and the other end is oscillatingly connected to the swing rod 321 away from the rotating push roller 322 via a pin. The connection point between the linear drive device 400 and the swing rod 321 is located on both sides of the swing axis of the swing rod 321, thereby controlling the swing of the swing rod 321 by the extension and retraction of the linear drive device 400.

[0041] Furthermore, such as Figure 9 As shown, the winding assembly 310 also includes a grating 330, which consists of a grating 330 transmitter and a grating 330 receiver. Both the grating 330 transmitter and receiver are fixed to the lower winding lifting platform by welding or threaded connection. The grating 330 receiver is electrically connected to the controller of the belt conveyor assembly 110. When the end of the ground fabric enters the grating 330, the belt conveyor assembly 110 can be stopped, thereby performing pushing and fabric pushing actions.

[0042] The grating 330 formed by the grating 330 transmitting device and the grating 330 receiving device is on a vertical plane whose horizontal diameter of the take-up air shaft 312 is far from the quarter line of the belt conveyor assembly 110. When the flooring fabric is in this position, the pusher mechanism 320 pushes the flooring fabric to adhere to the take-up drum at a position not exceeding a quarter circle, and the pusher mechanism 320 is most effective within this range.

[0043] Working principle: The operator can place the roll with flooring fabric on the unwinding assembly 210 on the upper lifting platform 200, and then adjust the upper lifting platform 200 to rise to the corresponding position on the first-layer belt conveyor assembly 110. The flooring fabric is manually pulled through the leveling assembly 220 and the traction conveyor assembly 230, and then the pneumatic traction conveyor assembly 230 is used to lift and transport the flooring fabric onto the belt conveyor assembly 110.

[0044] Once the flooring is fully laid on the belt conveyor assembly 110, the air pump connected to the ventilation duct 120 is driven, allowing airflow to be blown onto the flooring through the ventilation holes 111.

[0045] Once the flooring fabric has reached its drying time, the control system moves the lower lifting platform 300 to the discharge end of the corresponding belt conveyor assembly 110. The belt conveyor assembly 110 then starts, conveying the flooring fabric to the unloading guide table 311. After passing through the unloading guide at the end of the flooring fabric, it enters the upper surface of the push plate 3132 and directly enters the detection range of the grating 330. The belt conveyor assembly 110 then stops. A negative pressure is generated in the pressure box 3134 by an air pump to adsorb the flooring fabric. Then, the lifting frame 3131 rises under the action of the drive device until the flooring fabric adheres to the winding drum on the winding air shaft 312. Afterward, the pushing mechanism 320 operates, and the swing rod 321 drives the rotating push roller 322 to push the flooring fabric upward, causing it to adhere to the winding drum. At this point, the pressure box 3134 switches to a positive pressure state. The winding air shaft 312, under the action of the drive device, drives the winding drum to wind up.

[0046] The above describes the roll-up and drying process on the first-layer belt conveyor assembly 110.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
