Description

Technical Field

[0001] The utility model relates to textile equipment, in particular to a curtain fabric rolling rack. Background Art

[0002] Curtain fabric is a large wide fabric. The winding shaft used in the winding process is relatively long, and the curtain fabric is usually thicker. Therefore, for curtain fabric of the same length, a roll of curtain fabric is much larger in weight and diameter than traditional fabric rolls. If only a paper winding drum is used for winding, it is obviously unable to bear the weight, and it is bound to bend or even break during the winding process.

[0003] The existing method is to sleeve the paper reel on a metal shaft, and drive the paper reel to rotate together through the metal shaft, so as to provide support for the paper reel when the curtain fabric is rolled up to prevent. However, the existing problem is that before extracting the metal shaft, the curtain roll must be hoisted and suspended, and then the baffles fixed at both ends of the metal shaft can be removed, and finally the metal shaft can be extracted from the paper reel. This method of disassembling and assembling the metal shaft requires the enterprise to add additional hoisting equipment, which increases the burden on the enterprise. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figures 1 to 4 The curtain fabric reel shown in the figure includes a metal shaft 200, on which a paper reel 300 for reeling in curtain fabric is sleeved. It should be noted that the inner diameter of the paper reel is 2 to 3 mm larger than the outer diameter of the metal shaft, so that the paper reel can be smoothly sleeved on the metal shaft, and will not be excessively bent when the curtain fabric is subsequently reeled in. In addition, a set of baffle mechanisms 200 that can be disassembled along the extension line of the diameter are respectively installed at both ends of the metal shaft. When the metal shaft in the curtain fabric needs to be pulled out from the paper reel, it is only necessary to disassemble the baffle mechanisms clamped at both ends of the metal shaft along the extension direction of the diameter line. At this time, after the two ends of the metal shaft lose the clamping of the baffle mechanism, the curtain fabric roll itself falls to the ground, and the metal shaft can be easily pulled out from the paper reel.

[0026] Specifically, in this solution, the metal shaft includes a main body portion located in the middle part, which supports the paper winding drum. The main body 210 is hollow in the middle to ensure strength while reducing its weight as much as possible. In addition, two shaft ends 230 are coaxially connected at both ends of the main body, and the shaft ends are used to connect with the driving part of the winding mechanism. A circle of grooves 220 is arranged between the shaft ends and the main body. Specifically, the diameter of the groove is smaller than the diameter of the main body and the shaft end, so that the baffle mechanism entering the groove cannot slide axially on the metal shaft.

[0027] It should be noted that there are many types of disc-shaped mechanisms that can be split in half along the diameter of the baffle mechanism 100. Here, the applicant proposes the following specific method for reference and understanding. Specifically, the baffle mechanism 100 includes two groups of baffle assemblies 110, and the baffle assembly includes a semicircular baffle 111, and the center of the baffle has a semicircular groove that allows the metal shaft body to be exposed. A card plate 114 is arranged in the groove, and the card plate is semi-annular, and the thickness of the card plate is the same as the width of the card groove, so that the baffle will not shake after the card plate can be inserted into the card groove in a sliding fit. It should also be noted that when the card plate is inserted into the card slot, the two baffles are assembled and coaxially clamped on the body of the metal shaft. In addition, if Figure 2 As shown, the diameter of the semicircular groove of the baffle is slightly larger than the outer diameter of the body in the metal shaft, and is preferably optimally matched with the paper winding drum inserted therein, so that after the two baffles are assembled together, an annular groove can be formed for the end of the paper winding drum 300 to be inserted therein for transitional matching. It should be made clear that the purpose of setting the annular groove is to allow the two ends of the paper winding drum to have a margin that exceeds the inner surface of the baffle mechanism, so as to prevent the edge of the curtain fabric from being exposed outside the paper winding drum. In addition, the purpose of setting the annular groove is that, through other pressure devices, the baffle mechanism and the metal shaft can cooperate to clamp the paper winding shaft, thereby driving the paper winding shaft to rotate synchronously with the metal shaft to prevent the paper winding shaft from slipping.

[0028] Specifically, in this embodiment, in order to achieve the purpose of clamping the paper winding drum, an arc-shaped pressing block 113 is also included. The arc-shaped pressing block is embedded in the baffle. When the paper winding drum is inserted into the annular groove formed by the two baffles, the radially moving arc-shaped pressing block 113 will apply pressure to the paper winding drum. Specifically, the arc-shaped pressing block is rotatably connected to the end of the screw 112 screwed in the baffle. When the screw rotates, it moves radially inward toward the baffle, thereby driving the arc-shaped pressing block to apply pressure to the paper winding drum, and finally completing the clamping of the paper winding drum.

[0029] In addition, it should be noted that in this solution, the two baffles are detachably joined on the metal shaft mainly by means of the locking bolts 130. Specifically, two connecting plates 115 are provided on the outer surfaces of the two baffles, and the two connecting plates are provided along the joining surfaces of the baffles. Through holes are provided on the connecting plates 115, and after the locking bolts pass through the aligned through holes, the nuts can be tightened.

[0030] In addition, in some implementation examples, there is also the following manner. That is, a set of anti-slipping mechanisms 120 is also installed on the outer surface of one of the baffles. Specifically, the anti-slipping mechanism includes a fixed half ring 121 fixedly installed on the outer surface of the baffle, and a movable half ring 122 hinged to one end of the fixed half ring. The anti-slipping mechanism formed after the fixed half ring and the movable half ring are closed is coaxial with the metal shaft clamped by the two baffles, and it should be noted that the free ends of the fixed half ring and the movable half ring after closing are also fixed by locking bolts. In addition, it should be noted that the inner diameter of the anti-slipping mechanism is the same as the outer diameter of the shaft end of the metal shaft, so that after the anti-slipping mechanism is closed, it is clamped on the shaft end of the metal shaft to prevent the two baffles from falling off the metal shaft at the same time after the two baffles are disassembled. In this embodiment, the fundamental purpose of setting the anti-slip mechanism is that after the two baffles are disassembled, if the two baffles fall off from the metal shaft at the same time, the metal shaft will fall directly to the ground after being supported, and the worker who disassembles the baffle mechanism is very likely to be hit by the curtain roll. In order to prevent this situation from occurring, the two baffles need to be removed one by one. Specifically, when disassembling the baffle mechanism, first rotate the baffle that is not connected to the anti-slip mechanism to the upper part, and then remove the baffle first. At this time, the file connected to the anti-slip mechanism at the lower part is still fixedly connected to the metal shaft to play the role of supporting the curtain roll. When a baffle assembly is removed, the worker pushes the curtain roll forward, and because the remaining baffle assembly is semicircular, it will be very easy to roll. As the curtain roll rolls, the remaining baffle assemblies fixed at both ends of the metal shaft will flip to the upper part. At this time, the curtain roll falls to the ground, and the worker can remove the remaining baffle assemblies fixedly connected to the metal shaft. The safety of removing the baffle mechanism is effectively improved.

[0031] In addition, it should be noted that in order to reduce the weight of the baffle in the baffle mechanism as much as possible and facilitate workers to disassemble and carry it, a weight-reducing cavity 116 is opened in the baffle.

[0032] Working principle: When the curtain fabric needs to be rolled up, the paper winding drum is now sleeved on the metal shaft, and then the baffle assemblies are clamped on the shaft ends of the metal shaft in pairs. When the above steps are completed, the baffle assemblies are assembled into a whole by the locking bolts. Then the movable half ring and the fixed half ring of the anti-slip mechanism are closed and locked. After the anti-slip mechanism is fixed, the screw is turned to press the arc-shaped pressure block against the end of the paper winding shaft to ensure that the paper winding shaft can rotate synchronously with the metal shaft. When the above steps are completed, this solution can be installed on the winding mechanism to realize the winding of the curtain fabric. When the curtain fabric is rolled up, the curtain roll can be put down through the rolling mechanism. After the worker rolls the curtain roll placed on the ground to the loading and unloading site, he adjusts the state of the baffle mechanism so that the baffle assembly connected to the anti-slip mechanism is at the bottom. The function can first remove the upper baffle assembly, and then roll the curtain roll so that the baffle assembly connected to the anti-slip mechanism is flipped to the top, and then the anti-slip assembly and the baffle assembly are removed together. At this time, the metal shaft that has lost the clamping of the baffle mechanism can be easily and smoothly pulled out of the paper winding shaft. This solution does not require the use of a lifting device to remove the metal shaft, saving the company the cost of equipment investment. At the same time, the structure is simple, and disassembly and assembly are also convenient and quick.
