[0020] Embodiment

[0021] The present invention provides an improved sandpaper roll paper loading rack with convenient use. Referring to Figures 1-3 as shown, it includes a base 1. In the middle of the top end face of the base 1, a lifting cylinder is provided. The output end of the lifting cylinder is connected with a bearing plate 2 for placing the sandpaper roll 3 and having an arc-shaped inner side wall. A plurality of uniformly distributed mounting plates 5 are symmetrically arranged on the left and right sides of the bearing plate 2. The mounting plate 5 and the bearing plate 2 are of an integrally formed structure. On the top end face of the base 1 below the mounting plate 5, a fixed column 4 is provided. A sliding rod 17 with the top end fixedly connected to the bottom end face of the mounting plate 5 is slidably connected in the fixed column 4. Erection components are provided on the base 1 at the front and rear ends of the bearing plate 2. On one side of the bearing plate 2, a conveying rack for pushing the sandpaper roll 3 onto the bearing plate 2 is provided. Through the setting of the conveying rack, it is thus possible to avoid the staff from lifting the sandpaper roll 3 and placing it on the bearing plate 2, saving manpower and improving the installation efficiency of the sandpaper roll 3.

[0022] Among them, the erection component includes a support column 6. On the top of the side of the support column 6 close to the bearing plate 2, a connecting column 10 is provided. The connecting column 10 and the support column 6 are of an integrally formed L-shaped structure. A limiting groove is opened on the bottom end face of the connecting column 10. A limiting column 12 is slidably connected in the limiting groove. The bottom end face of the limiting column 12 is provided with a lifting ring 13 in the shape of a hollow cylinder. Through the setting of the lifting ring 13, it is thus possible to fix the sandpaper roll 3 without affecting the access and processing of the sandpaper.

[0023] Furthermore, trapezoidal guide blocks 18 are symmetrically arranged on both sides of the limiting column 12. Guide grooves adapted to the guide blocks 18 are opened on both inner side walls of the limiting groove. Through the setting of the guide grooves and the guide blocks 18, the stability of the displacement of the limiting column 12 in the limiting groove is improved.

[0024] Further, a first connection hole 19 for inserting the connection bolt 11 is formed through the limiting column 12, and a plurality of second connection holes 14 which are equidistantly distributed and communicate with the first connection hole 19 are formed through the connection column 12. By the arrangement of the first connection hole 19 and the second connection hole 14 in cooperation with the connection bolt 11, the displacement of the lifting ring 13 is avoided. At the same time, the arrangement of the plurality of second connection holes 14 can meet the hoisting and fixing of the rolling shafts on the sandpaper rolls 3 with different lengths, greatly improving the applicability.

[0025] Further, an extension column 15 is provided at one end of the bottom end face of the connection column 10 close to the bearing plate 2, and an abutting plate 16 with an arc-shaped structure is provided on the bottom end face of the extension column 15. By the arrangement of the abutting plate 16, the upward displacement of the sandpaper roll 3 can be limited, facilitating the staff to sleeved the lifting ring 13 on the rolling shaft of the sandpaper roll 3.

[0026] Wherein, the conveying frame includes a baffle 7 arranged on the base 1, and the height of the baffle 7 is the same as the height of the bearing plate 2 in the non-lifted state, so as to facilitate the staff to push the sandpaper roll 3 onto the bearing plate 2. On the side of the baffle 7 away from the bearing plate 2, there are two oppositely arranged side plates 8 with one end lapped on the ground, and a plurality of conveying rollers 9 which are equidistantly distributed and rotatably connected are arranged between the two side plates 8.

[0027] The working principle of the present utility model is as follows:

[0028] When installing the sandpaper roll 3, the staff pushes the sandpaper roll 3 onto the conveying frame, and the sandpaper roll 3 is pushed onto the bearing plate 2 through the conveying rollers 9 on the conveying frame. The lifting cylinder is started to drive the bearing plate 2 and the sandpaper roll 3 to move upward until the outer side surface of the rolling shaft on the sandpaper roll 3 is in contact with the inner side wall of the abutting plate 16. At this time, the sliding limiting column 12 drives the lifting ring 13 to move towards the rolling shaft until the lifting ring 13 is sleeved on the outer side of the rolling shaft of the sandpaper roll 3. At this time, the first connection hole 19 on the limiting column 12 communicates with one of the second connection holes 14 on the connection column 10, and the connection bolt 11 is inserted into the communicated first connection hole 19 and second connection hole 14 for fixation, so as to avoid the displacement of the lifting ring 13. Finally, the lifting cylinder is started to drive the bearing plate 2 to move downward, thus completing the installation of the sandpaper roll 3. The structure of the present utility model is simple, making the installation of the sandpaper roll 3 more convenient and efficient.
