[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] See also Figure 1-Figure 2 The embodiment of the utility model provides a reeling and unwinding device, including a first vertical plate 1, a second vertical plate 2, a connecting member 3, an inflatable shaft 4 and a supporting member 5. The first vertical plate 1 and the second vertical plate 2 are arranged vertically and parallelly at intervals, the connecting member 3 connects the first vertical plate 1 and the second vertical plate 2, the inflatable shaft 4 is arranged between the first vertical plate 1 and the second vertical plate 2 and is respectively connected and fixed to the first vertical plate 1 and the second vertical plate 2, the inflatable shaft 4 is used to place the unwinding coil, the supporting member 5 is respectively arranged on the first vertical plate 1 and the second vertical plate 2 and is located below the inflatable shaft 4, and the supporting member 5 is used to hold the inflatable shaft 4 when the inflatable shaft 4 falls off from the first vertical plate 1 or the second vertical plate 2.

[0029] By arranging a support member 5 under the inflatable shaft 4, when the connection between the two ends of the inflatable shaft 4 and the first vertical plate 1 or the second vertical plate 2 falls off, the support member 5 can lift the inflatable shaft 4 to prevent the inflatable shaft 4 and the unwinding coil from falling on the equipment parts or personnel below, thereby avoiding damage to the equipment or injury to personnel.

[0030] The utility model provides a corresponding support member 5 below the inflatable shaft 4 for installing the unwinding coil in the unwinding device to protect the inflatable shaft 4 from falling off due to excessive weight, thereby avoiding damage to the equipment or injury to personnel.

[0031] In this embodiment, the connecting member 3 can be a square tube, and the two ends of the square tube are respectively welded to the first vertical plate 1 and the second vertical plate 2 as a whole, so that the first vertical plate 1 and the second vertical plate 2 can form an integrated structure.

[0032] See also Figure 2 Furthermore, the side of the support member 5 facing the inflatable shaft 4 is a V-shaped surface 5a. The V-shaped surface 5a is provided so that the inflatable shaft 4 will eventually stay in the middle of the V-shaped surface 5a when it falls, so as to prevent the inflatable shaft 4 from sliding out of the support member 5 and thus the support member 5 from losing its supporting function for the inflatable shaft 4. This design scheme can ensure that the support member 5 stably supports the inflatable shaft 4 while facilitating the processing of the support member 5.

[0033] Furthermore, in addition to being set as a V-shaped surface 5a on the other side of the inflatable shaft 4, the inflatable shaft 4 can also be set as a plane on the side of the support member 5 facing the inflatable shaft 4, and blocking parts (not shown in the figure) are provided on the opposite sides of the plane. A space for accommodating the inflatable shaft 4 is formed between the two blocking parts, that is, a U-shaped structure is formed between the blocking parts located on the opposite sides of the plane and the plane, which can also better receive the inflatable shaft 4, thereby preventing the inflatable shaft 4 from slipping off the support member 5.

[0034] See also Figure 3 Further, the support member 5 includes a fixing portion 51 fixed on the first vertical plate 1 or the second vertical plate 2 and a supporting portion 52 arranged on the fixing portion 51, the supporting portion 52 is used to hold the inflatable shaft 4, the fixing portion 51 supports the supporting portion 52, and the side of the supporting portion 52 facing the inflatable shaft 4 is set as a V-shaped surface 5a or a plane. In this way, the support member 5 adopts a split structure setting, and only the V-shaped surface 5a is processed or the blocking portion is set on the supporting portion 52, which can greatly reduce the processing steps. At the same time, the position of the supporting portion 52 on the fixing portion 51 can be adjusted to facilitate the adjustment of the supporting portion 52 to the bottom of the inflatable shaft 4. Specifically, the supporting portion 52 can be set at one end of the fixing portion 51 away from the first vertical plate 1 or the second vertical plate 2, that is, the supporting portion 52 on the first vertical plate 1 is set at one end of the fixing portion 51 away from the first vertical plate 1, and the supporting portion 52 on the second vertical plate 2 is set at one end of the fixing portion 51 away from the second vertical plate 2, so that the material cost of the supporting portion 52 can be saved.

[0035] See also Figure 4 Furthermore, the length L of the support member 5 is 2 to 3 times the diameter of the inflatable shaft 4, so that the support member 5 can catch the inflatable shaft 4 intact after the inflatable shaft 4 falls off, preventing the inflatable shaft 4 from falling empty.

[0036] See also Figure 3 , Figure 5Furthermore, a rotating disk 6 is provided on each of the first vertical plate 1 and the second vertical plate 2, and the two ends of the inflatable shaft 4 are respectively mounted on the rotating disk 6. The rotating disk 6 is provided with a receiving groove 6a for accommodating the inflatable shaft 4, and an opening (not shown in the figure) for the inflatable shaft 4 to enter and exit is provided above the receiving groove 6a. The rotating disk 6 can drive the inflatable shaft 4 to rotate. In this way, when installing the unloading coil, the inflatable shaft 4 passes through the center of the unloading coil and the two ends extend out of the unloading coil. After the special equipment lifts the inflatable shaft 4 and the unloading coil, the two ends of the inflatable shaft 4 enter the receiving groove 6a from the opening, thereby realizing the installation of the inflatable shaft 4.

[0037] See also Figure 5 Specifically, a driving member 8 is provided on the first vertical plate 1 or the second vertical plate 2, a driving end of the driving member 8 is connected to the rotating disk 6 on the first vertical plate 1 or the second vertical plate 2, and the driving member 8 drives the rotating disk 6 to rotate.

[0038] See also Figure 3 Further, the rotating disk 6 includes a rotating portion 61 rotatably provided on the first vertical plate 1 or the second vertical plate 2 and a supporting portion 62 provided on the side of the rotating portion 61 away from the first vertical plate 1 or the second vertical plate 2, that is, the supporting portion 62 on the first vertical plate 1 is provided on the side of the rotating portion 61 away from the first vertical plate 1, and the supporting portion 62 on the second vertical plate 2 is provided on the side of the rotating portion 61 away from the second vertical plate 2, the supporting portion 62 is coaxially arranged with the rotating portion 61, and the accommodating groove 6a is opened in the supporting portion 62. In this way, the supporting portion 62 can make the inflatable shaft 4 coaxially arranged with the rotating portion 61 through the supporting portion 62, so that the rotating disk 6 can drive the inflatable shaft 4 to rotate around its own axis.

[0039] See also Figure 3 Furthermore, the accommodating groove 6a is a square groove, and the end of the inflatable shaft 4 is provided with a square connecting portion 41 that can cooperate with the accommodating groove 6a. In this way, when the rotating disk 6 drives the inflatable shaft 4 to rotate, the inflatable shaft 4 itself can be prevented from slipping, thereby affecting the unloading of the unloading coil.

[0040] See also Figure 2 , Figure 3 Furthermore, the reeling and unwinding device further includes a locking member 7 disposed on the rotating disk 6 to lock the inflatable shaft 4 in the receiving groove 6a. The locking member 7 can better fix the inflatable shaft 4 in the receiving groove 6a, and can prevent the inflatable shaft 4 from falling off the rotating disk 6.

[0041] See also Figure 3Specifically, the locking member 7 includes a locking portion 71 disposed on the rotating disk 6 and sleeved on the outside of the receiving groove 6a, and a limiting member (not shown) penetrating the locking portion 71 and the receiving groove 6a, that is, the locking portion 71 is sleeved on the outside of the supporting portion 62 to wrap the receiving groove 6a, thereby closing the opening of the receiving groove 6a. The limiting member can lock the locking portion 71 with the supporting portion 62, thereby preventing the inflatable shaft 4 from falling out of the opening of the receiving groove 6a.

[0042] Specifically, the locking portion 71 may be an annular portion, and the supporting portion 62 may be a prism structure. The supporting portion 62 of the prism structure can avoid the smooth contact with the locking portion 71 and thus avoid slipping. Specifically, the prism may be a triangular prism, a quadrangular prism, a pentagonal prism, etc., which are not limited here. In this embodiment, the supporting portion 62 adopts a quadrangular prism structure, that is, a square structure. Compared with the triangular prism structure, the quadrangular prism can withstand greater force and is easier to process than other prism structures.

[0043] See also Figure 2 , Figure 3 Furthermore, the limiting member can be a columnar structure, the locking portion 71 is provided with a first through hole 711 passing through it, and the supporting portion 62 is provided with a second through hole 621 passing through it, the first through hole 711 and the second through hole 621 correspond to each other, and the limiting member is sequentially penetrated with the first through hole 711 and the second through hole 621 to connect the locking member 7 and the supporting portion 52.

[0044] The embodiment of the utility model further provides a digital printing device, including the aforementioned winding and unwinding device. The digital printing device provided by the utility model provides a corresponding support member 5 under the inflatable shaft 4 for installing the unwinding coil in the winding and unwinding device to protect the inflatable shaft 4 from falling off due to excessive weight, thereby avoiding damage to the device or injury to personnel.
