[0002] PVC film, full name polyvinyl chloride film, is a widely used plastic film material, mainly made of polyvinyl chloride (PVC) resin by calendering or blow molding, and is commonly used in packaging and construction. Existing PVC film rolls are usually stored in a direct stacking manner after production, which will cause the rolls to be squeezed and deformed and inconvenient for subsequent transportation. Therefore, it is necessary to design a PVC film roll storage mechanism. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a PVC film material roll storage mechanism.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a PVC film material roll storage mechanism, including a base, characterized in that a protective cover is also installed on the base, the protective cover is provided with a feed inlet and a discharge port, a placement rack is rotatably installed in the protective cover through a mounting seat, the placement rack is provided with a plurality of placement grooves for placing material roll rollers, a locking mechanism is provided at the placement groove, the end of the placement rack is connected to a handle through a transmission mechanism, and a universal wheel is installed at the bottom of the base.

[0005] The working principle of the utility model is as follows: the two ends of the rolled PVC film material roll are placed in the placement grooves on the placement rack at the feed inlet and locked by the locking mechanism, and then the placement rack is controlled to rotate by the handle, and multiple PVC film material rolls are placed on the placement rack in turn. When the placement rack is full of PVC film material rolls, the entire PVC film material roll can be transported by the universal wheel at the bottom of the base; when we need to take away the PVC film material roll, the locking mechanism is unlocked at the feed inlet, and then the handle is turned to control the placement rack to rotate. When the PVC film material roll rotates to the discharge port, it separates from the placement rack under the action of gravity, and the unloading of the PVC film material roll is completed.

[0006] The locking mechanism comprises a locking pin which is slidably mounted on a placement rack, one end of which is provided with a thread, the placement rack is provided with a thread groove which matches the thread at the end of the locking pin, and the other end of the locking pin is provided with an extension sheet.

[0007] With the above structure, after the end of the locking pin is aligned with the thread groove, the locking pin is threadedly connected to the placement frame through the extension piece to achieve locking of the end of the PVC film material roll.

[0008] The transmission mechanism includes a main gear, a driven gear 1, a driven gear 2 and a sub-gear. The main gear is connected to the handle through a connecting shaft, and the main gear is meshedly connected with the driven gear 1. The driven gear 1 is rotatably installed in the mounting seat through a rotating shaft. The driven gear 2 is also installed on the rotating shaft. The driven gear 2 is meshedly connected with the sub-gear, and the sub-gear is installed at the end of the central axis of the placement frame.

[0009] With the above structure, the handle is rotated to control the driving wheel to rotate, and under the transmission action of the driven gear 1 and the driven gear 2, the auxiliary gear is driven to rotate, thereby realizing the rotation of the placement rack.

[0010] A limiting portion is also provided on the locking pin, and a receiving groove matched with the limiting portion is provided on the inner side of the placement groove.

[0011] With the above structure, the locking pin is limited by the limiting part to prevent the locking pin from being disengaged, and the installation of the PVC film material roll is ensured by the storage groove.

[0012] A guide piece is also installed at the discharge port.

[0013] With the above structure, the guide member plays a buffering and guiding role when the PVC film material roll is separated from the placement rack due to gravity.

[0014] The bottom of the base is arranged in an arch shape.

[0015] The above structure is adopted to increase the overall stability.

[0016] Compared with the prior art, the PVC film material roll storage mechanism has the following advantages: the utility model can independently store the PVC film material roll by arranging a three-dimensional separated placement structure, and is also convenient for transfer and transportation.
