The columns 102 are vertically arranged with the top crossbeam 101. The bottom end of the column 102 is fixedly connected with a support beam 103, and the support beam 103 is vertically arranged with the column 102. A diagonal brace 104 is arranged between the support beam 103 and the column 102 to increase the stability of the column 102. Foot pads 105 are arranged at both ends of the bottom surface of the support beam 103. Bolt holes are opened on the foot pads 105, and the frame 1 is fixed to the ground by bolts.

[0019] A bottom cross beam 106 is connected between the two support beams 103 . Two bottom cross beams 106 are provided. The two bottom cross beams 106 are arranged in parallel. The middle parts of the two bottom cross beams 106 are connected by a connecting rod 107 . By arranging the bottom cross beam 106 between the two support beams 103 , the stability of the bottom of the frame 1 is increased.

[0020] A lifting bracket 2 is slidably connected between the two columns 102, and a flip bracket 3 is rotatably connected to the lifting bracket 2. A back sponge fixing mechanism 4 is arranged on the flip bracket 3. A back cover supporting mechanism 5 is also arranged at the lower part of the frame 1. The back sponge 6 is fixed to the flip bracket 3 through the back sponge fixing mechanism 4, and the back cover 7 is reversely covered on the back cover supporting mechanism 5. The back sponge 6 is driven by the lifting bracket 2 to move downward at a fixed angle, and the back cover 7 reversely covered on the back cover supporting mechanism 5 is pressed, so that the reverse back cover 7 is quickly turned over and covered on the back sponge 6 moving downward, thereby completing the covering of the back cover 7.

[0021] Specifically, slide rails 108 are provided on the opposite side surfaces of the column 102, and the slide rails 108 are arranged along the length direction of the column 102. The lifting bracket 2 is n-shaped, including a lifting beam 201 and a lifting longitudinal beam 202 vertically arranged at both ends of the lifting beam 201. A plurality of sliders are provided on the side of the lifting longitudinal beam 202 close to the slide rail 108. The plurality of sliders are slidably connected to the slide rail 108, so that the lifting bracket 2 can slide along the slide rail 108.

[0022] An electric cylinder 203 is arranged on the rear side of the lifting bracket 2. The bottom end of the electric cylinder 203 is fixed on the connecting rod 107 at the bottom of the frame 1. The telescopic end of the electric cylinder 203 is connected to the middle part of the lifting beam 201 through a connecting seat. The telescopic end of the electric cylinder 203 is extended and retracted to drive the lifting bracket 2 to realize the lifting movement.

[0023] A flip bracket 3 is rotatably connected between the two lifting longitudinal beams 202. The flip bracket 3 is n-shaped, including a flip beam 301 and flip longitudinal beams 302 vertically fixed at both ends of the flip beam 301. A rotating shaft is arranged on the side of the bottom end of the flip longitudinal beam 302 near one side of the lifting longitudinal beam 202. A rotating shaft seat is arranged at the corresponding position of the lifting longitudinal beam 202 and the rotating shaft seat. The rotating shaft is rotatably connected to the rotating shaft seat, so that the flip bracket 3 can rotate inside the lifting bracket 2, so that the angle of the back sponge 6 can be manually adjusted when covering the back cover 7, which is convenient for covering.

[0024] In order to ensure that the flipping of the flip bracket 3 does not interfere with the electric cylinder 203, limit plates 204 are set at both ends of the bottom of the lifting beam 201. The limit plates 204 are set on the side of the lifting beam 201 close to the electric cylinder 203. When the flip bracket 3 rotates to the upper side, the flip bracket 3 is limited by the limit plates 204, so that the flip bracket 3 can only flip toward the side away from the electric cylinder 203. In addition, limiting columns 205 are also provided on the two flip longitudinal beams 302. The limiting columns 205 are fixed to the side of the flip longitudinal beam 302 close to the electric cylinder 203 through a mounting seat. The end of the limiting column 205 away from the mounting seat extends to the rear side of the lifting longitudinal beam 202. The mounting seat moves the limiting column 205 away from the side of the flip longitudinal beam 302, so that a set distance is set between the limiting column 205 and the flip bracket 3, so that the flip bracket 3 has space for flipping. When the flip bracket 3 flips to a certain angle, the limiting column 205 contacts the lifting longitudinal beam 202, thereby limiting the flip bracket 3 from continuing to rotate, thereby limiting the rotation angle of the flip bracket 3.

[0025] The flip beam 301 is also provided with a back sponge fixing mechanism 4 for fixing the back sponge 6. Figure 3 As shown, the back sponge fixing mechanism 4 includes two symmetrically arranged cylinders 401, a fixing seat 402 is symmetrically arranged between the two cylinders 401, a fixing hole is opened on the fixing seat 402, a fixing rod 403 is fixedly connected to the telescopic shaft of the cylinder 401, the fixing rod 403 passes through the fixing hole on the fixing seat 402, and the fixing seat 402 is used to support the fixing rod 403.

[0026] When in use, first place the back sponge 6 between the two fixing seats 402, and align the mounting holes on both sides of the back sponge 6 with the fixing rods 403 on both sides respectively. The cylinder 401 drives the fixing rods 403 to be inserted into the mounting holes, thereby fixing the back sponge 6 on the flip bracket 3.

[0027] The back cover support mechanism 5 is arranged on the front side of the flip bracket 3, and the back cover support mechanism 5 includes a connecting plate 501 and support plates 502 vertically fixed on the front and rear sides of the connecting plate 501. The connecting plate 501 is arranged at the bottom ends of the two support plates 502 and fixed in the middle of the bottom cross beam 106. A plurality of pulleys 503 are arranged side by side at the top of the support plate 502. By arranging a plurality of pulleys 503 at the top of the support plate 502, the axes of the plurality of pulleys 503 coincide with each other. By arranging a plurality of pulleys 503 at the top of the two support plates 502, the flipping of the back cover 7 is facilitated.

[0028] When using, Figure 4 and Figure 5, as shown, the back cover 7 is reversely covered on the outside of the two support plates 502, and the two support plates 502 support the back cover 7. The back sponge 6 moves between the two support plates 502 under the drive of the lifting bracket 2 and the flip bracket 3. Under the downward pressure of the lifting bracket 2, the back cover 7 is quickly flipped and covered on the outside of the back sponge 6, thereby completing the installation of the back cover 7.

[0029] A control cabinet 8 is also provided on one side of the frame 1, and a controller is provided in the control cabinet 8. The controller is electrically connected to the solenoid valves of the electric cylinder 203 and the air cylinder 401 respectively. The controller is connected to multiple foot switches 9. The movement of the electric cylinder 203 and the air cylinder 401 is controlled by the foot switches 9, thereby realizing the covering work of the back cover 7.

[0030] The multiple foot switches 9 are respectively the first foot switch, the second foot switch and the third foot switch, which are all electrically connected to the controller, wherein the first foot switch and the second foot switch are used to control the movement of the air cylinder 401 and the electric cylinder 203, the first foot switch is used to fix the back sponge 6 and lower the lifting bracket 2, the second foot switch is used to control the lifting bracket 2 to rise, the third foot switch is an emergency stop switch, and the device stops moving immediately when the third foot switch is pressed, thereby avoiding safety accidents.
