[0002] The material shaft is a common workpiece in the processing of plastic film products. By installing the material shaft on the relevant processing equipment, the automatic unloading and rewinding of the material roll can be realized. When processing products of different sizes, the processing equipment needs to replace different types of material shafts, and the material shafts need to be disassembled regularly for maintenance. These processes require short-distance transportation of the material shaft.

[0003] The applicant's workshop operators found that the traditional technology often uses a gantry (such as Figure 1 The carrier (as shown in the figure) is used to transport the material shaft. The gantry frame is equipped with a screw rod. The bottom of the screw rod is integrally connected to a clamp block. The height of the screw rod is adjusted so that the clamp block can squeeze and fix the material shaft. This method often has the following defects: the material shaft will generate a reaction force on the clamp block when it is squeezed and clamped. Long-term use and / or uneven force can easily damage the clamp block, causing the clamp block to fall off. Although the screw rod itself can squeeze and fix the material shaft after the clamp block falls off, the fixing effect is poor and it is easy to cause scratches and pits on the surface of the material shaft, which has an adverse effect on the performance and service life of the material shaft.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] As Figure 1 shown, in the prior art, the screw directly acts on the clamping block to squeeze and fix the material shaft, resulting in problems such as easy detachment of the clamping jaws and poor fixing effect. Therefore, this embodiment provides a supporting device for the material shaft.

[0029] Please refer to Figure 2 and Figure 3 , this embodiment provides a transport vehicle for a material shaft, including a trolley body 8, a supporting device installed on the trolley body 8, and a lifting mechanism 9 provided on the trolley body 8 and used to adjust the height of the bottom plate 1.

[0030] Please refer to Figures 4 to 8 , the supporting device of the present utility model includes a bottom plate 1, a first support seat 21, and a second support seat 22.

[0031] The bottom plate 1 is fixedly connected to the movable frame 92 of the lifting mechanism 9 to achieve its own lifting. By adjusting the height of the bottom plate 1, the fixing position of the material shaft on the supporting device can be aligned with the material shaft installation position of the production equipment, thereby completing the replacement or disassembly of the material shaft.

[0032] Both the first support seat 21 and the second support seat 22 are fixed on the bottom plate 1. Among them, the top of the first support seat 21 is provided with a concave arc-shaped groove, and the diameter of the arc-shaped groove matches the diameter of the material shaft joint 41. The top of the second support seat 22 is also provided with a concave arc-shaped groove, and the diameter of the arc-shaped groove matches the diameter of the material shaft body 42.

[0033] The joint and the body of the material shaft can be respectively placed on the first support seat 21 and the second support seat 22, and the initial fixation is achieved by using the opening and closing cover plate 3 movably connected to the first support seat 21. When the cover plate 3 is closed with the first support seat 21, an installation hole 40 for clamping the material shaft joint 41 is formed. The first support seat 21 is also provided with an adjustment component 5 that can lock the cover plate 3 in the closed state.

[0034] The adjustment component 5 includes an adjustment screw 51; one end of the adjustment screw 51 is installed on the first support seat 21, and the other end is threadedly connected with an adjustment nut 52; one side of the cover plate 3 is hinged on the first support seat 21, and the other side can be abutted and locked by rotating the adjustment nut 52.

[0035] In this embodiment, on the same side of the first support base 21 and the cover plate 3, grooves 6 are provided which are in communication with each other and are used to avoid the movement of the adjusting screw rod 51. One end of the adjusting screw rod 51 can be hinged in the groove 6 of the first support base 21, and the adjusting screw rod 51 can be rotated to make its axial direction in the vertical state. At this time, the bottom of the adjusting nut 52 can abut against the top of the cover plate 3. In addition, an anti-slip gasket 53 can be fixedly connected to the abutting end of the adjusting nut 52, so as to enhance the friction force when abutting and prevent the lock from loosening.

[0036] On the side of the cover plate 3 where the groove 6 is provided, a first handle 71 is further provided, which is convenient for the operator to manually lift or lower the cover plate 3 and adjust the hinged angle of the cover plate 3.

[0037] As Figure 5 shown, when the cover plate 3 is not closed with the first support base 21, the corresponding part of the material shaft can be placed on the two support bases. Then as Figure 6 shown, lower the cover plate 3. At this time, the adjusting screw rod 51 is in the natural horizontal state. Then as Figure 7 shown, turn the adjusting screw rod 51 to the vertical state. Finally as Figure 8 shown, tighten the adjusting nut 52 in a clockwise direction, so that the bottom of the anti-slip gasket 53 is in close contact with the top of the cover plate 3, so as to ensure that the cover plate 3 is locked in the closed state. In this way, during the transportation of the material shaft, it can be ensured that the material shaft is relatively fixed. And because the material shaft joint 41 is in contact with the inner wall of the mounting hole 40, although the adjusting screw rod 51 finally acts on locking the material shaft, the overall belongs to an indirect action, and it is not easy to damage the material shaft and its own structure even after long-term use, thus having a beneficial effect on the performance and service life of the device itself and the material shaft.

[0038] The lifting mechanism 9 can be realized by a linear motor + sprocket chain. Of course, in other embodiments, a telescopic member such as a cylinder can also be used to directly drive the bottom plate 1 to lift.

[0039] In this embodiment, the lifting mechanism 9 includes slide rails 91, a movable frame 92, a fixed frame 93, a telescopic member 94, sprockets 95 and a chain 96; there are two slide rails 91, which are respectively fixedly connected to the opposite sides of the top of the trolley body 8; both ends of the movable frame 92 are slidably connected to the two slide rails 91 through pulleys; both ends of the fixed frame 93 are fixedly connected to the two slide rails 91; the telescopic member 94 can be a linear motor, its bottom is fixedly connected to the trolley body 8, and the top of the telescopic member 94 is an extended end and is equipped with a rotatable sprocket 95; the sprocket 95 cooperates with the chain 96, one end of the chain 96 is fixedly connected to the fixed frame 93, and the other end of the chain 96 is fixedly connected to the movable frame 92.

[0040] When the linear motor extends, it drives the sprocket 95 to rise. At this time, the chain 96 will also move together with the sprocket 95. Meanwhile, the sprocket 95 will rotate, and finally the movable frame 92 will be lifted.

[0041] Two second handles 72 are respectively and fixedly connected to the two slide rails 91, which is convenient for the operator to push and pull the trolley body 8. In some embodiments, universal casters with a self-locking function may also be provided at the bottom of the trolley body 8.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
