[0035] The protective device includes a carrying plate 191, a hollow tube 192, an arc-shaped sheet 193, a sliding plate 194, a plurality of rectangular plates 195, a Z-shaped rod 196, a spring sheet 197 and a stop block 198. The carrying plate 191 is fixedly mounted on a side of the outer frame 8 close to the contact plate 15. The hollow tube 192 slides through the inner and outer walls of the carrying plate 191. The arc-shaped sheet 193 is fixedly mounted on the circumferential surface of the hollow tube 192. The sliding plate 194 slides through a side of the carrying plate 191 away from the outer frame 8. A plurality of rectangular plates 195 are fixedly mounted on a side of the sliding plate 194 close to the arc-shaped sheet 193.

[0036] A No. 1 limit groove is provided on one side of the carrying plate 191 close to the limit block 198, and a No. 2 limit groove is provided on one side of the carrying plate 191 close to the No. 1 limit groove. The limit block 198 contacts the inner wall of the No. 1 limit groove. The position of the sliding plate 194 can be quickly adjusted through standardized operation, so that the operator can enable or close the rectangular plate 195 according to actual conditions, simplifying the operation process.

[0037] When the present embodiment is working, when the contact plate 15 moves upward, the contact plate 15 moves to drive the long rod 186 to move upward, and the long rod 186 moves to drive the abutment plate 187 to move upward, and the inclined surface 3 of the abutment plate 187 squeezes the arc surface 1 during the movement, and the round rod 183 is squeezed to move in the direction away from the receiving plate 11, and the round rod 183 moves to drive the rubber plate 184 to move in the direction of the hollow frame 181, and the rubber plate 184 moves to drive the friction plate 188 to move in the direction of the hollow frame 181, and the corrugation 2 of the friction plate 188 contacts the inner wall of the hollow frame 181 during the movement, and friction is generated between the corrugation 2 and the hollow frame 181, and this friction makes the friction plate 188 contact the hollow frame 181 more closely, thereby increasing the contact stability, and the rubber plate 184 stops moving after moving to the specified position, so that the goods are not hindered by the rubber plate 184 when moving in the direction of the outer frame 8, and the synchronous movement of the rubber plate 184 and the friction plate 188 reduces the overall operation time, so that the goods can be smoothly moved to The outer frame 8 moves in the direction of the outer frame 8, thereby ensuring the continuity of the unloading and stacking operation. When the contact plate 15 is reset downward, the thrust exerted by the contact plate 15 on the long rod 186 gradually decreases, so that the deformed No. 2 spring 185 recovers and drives the rubber plate 184 to move away from the hollow frame 181. The movement of the rubber plate 184 drives the round rod 183 to move toward the receiving plate 11. The arc surface 1 of the round rod 183 squeezes the inclined surface 3 during the movement, and the push plate 187 is squeezed and moves downward. The movement of the push plate 187 drives the long rod 186 to move downward. At the same time, the movement of the rubber plate 184 drives the friction plate 188 to move away from the hollow frame 181. The friction plate 188 separates from the hollow frame 181 during the movement, and then the corrugation 1 of the rubber plate 184 contacts the outer side wall of the goods during the movement. The rubber plate 184 continues to move to clamp the goods. The rubber plate 184 effectively clamps the goods to ensure that the goods can maintain a relatively stable position during transportation, reducing potential damage or operational difficulty caused by displacement.

[0038] When the long rod 186 moves upward, the long rod 186 moves to drive the hollow tube 192 upward, and the hollow tube 192 moves to drive the arc piece 193 upward. The curved surface of the arc piece 193 contacts the second curved surface of the rectangular plate 195 during the movement, and the second curved surface applies resistance to the arc piece 193. The arc piece 193 bends downward under the influence of the resistance, and the arc piece 193 continues to move and separates from the second curved surface, so that the arc piece 193 recovers under the action of its own elasticity. When the long rod 186 moves downward, the long rod 186 moves to drive the hollow tube 192 downward, and the hollow tube 192 moves to drive the arc piece 193 downward. The inner concave surface of the arc piece 193 contacts the top of the rectangular plate 195 during the movement, and the rectangular plate 195 exerts resistance on the arc piece 193. When resistance is applied, the arc piece 193 bends upward due to the resistance, and when the arc piece 193 continues to move and separates from the rectangular plate 195, the deformed arc piece 193 quickly recovers under the action of its own elasticity, and the arc piece 193 collides with the second rectangular plate 195 during the recovery process to generate vibration, and then the arc piece 193 repeats the above movement and collides with multiple rectangular plates 195 to generate continuous vibration, and the rectangular plate 195 transmits the vibration to the round rod 183 and the abutment plate 187 to promote the smooth movement of the round rod 183 and the abutment plate 187, and transmits the vibration generated by the collision to the round rod 183 and the abutment plate 187 through the rectangular plate 195, which helps to improve the smoothness of the overall movement, thereby reducing the jamming during the unloading process, reducing the frequency of shutdown maintenance, and operating When the operator does not need to use the rectangular plate 195, the Z-shaped rod 196 is manually pulled to move in the direction away from the sliding plate 194. The Z-shaped rod 196 stretches the spring sheet 197 during the movement. The spring sheet 197 is stretched and deformed. At the same time, the Z-shaped rod 196 moves to drive the limit block 198 to move in the direction away from the mounting plate 191. The limit block 198 is separated from the No. 1 limit groove during the movement, so that the limit imposed by the limit block 198 on the sliding plate 194 is released, and the Z-shaped rod 196 is pulled to move in the direction away from the hollow tube 192. The movement of the Z-shaped rod 196 drives the sliding plate 194 to move in the direction away from the hollow tube 192. The movement of the sliding plate 194 drives the rectangular plate 195 to move in the direction away from the hollow tube 192. At the same time, the Z-shaped rod 196 moves The limit block 198 is driven to move in the direction away from the hollow tube 192. After the limit block 198 moves to the specified position, the Z-shaped rod 196 is released, so that the deformed spring piece 197 is restored and drives the Z-shaped rod 196 to move in the direction of the sliding plate 194. The movement of the Z-shaped rod 196 drives the limit block 198 to move in the direction of the carrying plate 191. The limit block 198 contacts the inner wall of the No. 2 limit groove during the movement, so that the limit block 198 applies a limit to the sliding plate 194. At the same time, the arc piece 193 does not contact the rectangular plate 195 during the movement. The position of the sliding plate 194 can be quickly adjusted through standardized operations, so that the operator can enable or close the rectangular plate 195 according to the actual situation, which simplifies the operation process and helps to improve the overall unloading and stacking efficiency.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
