DETAILED DESCRIPTION

[0027] The advantages and features of the present application can be more easily understood by those skilled in the art from the preferred embodiments of the present application in conjunction with the accompanying drawings, so as to make the protection scope of the present application more clearly defined.

[0028] Referring to the accompanying drawings Figures 1 to 5 The automatic lifting hopper mechanism in the embodiment comprises:

[0029] A hopper mounting frame 1 is provided with a circular circulating track 2 along the height direction thereof;

[0030] A hopper 5 is used for supporting and placing a plurality of empty rubber plate, and a plurality of the hoppers are detachably arranged on the outer periphery of the circulating track 2; a plurality of empty rubber plates are stacked and placed on the hopper from bottom to top in sequence, so that the empty rubber plates can be batch fed.

[0031] In some embodiments, the empty rubber plate taking position is arranged at the topmost part of the circulating track 2, which facilitates taking the empty rubber plates in the hopper and does not interfere in the vertical direction when taking the empty rubber plates. The arrangement of the circulating track 2 enables the track to drive the plurality of hoppers to move synchronously during rotation. When the empty rubber plates in the hopper at the topmost part of the circulating track 2 are completely taken, the circulating track 2 is rotated, so that the hopper at the second height filled with empty rubber plates moves upward to the topmost part of the circulating track 2 at this moment, and the empty rubber plates in the hopper can be continuously taken, thereby realizing uninterrupted circulation of the empty rubber plates and effectively improving the feeding speed of the empty rubber plates. At the same time, the hopper at the bottommost part of the circulating track 2 after the above rotation can also be replenished with empty rubber plates.

[0032] In addition, the hopper may be damaged after long-term use, and the detachable arrangement of the hopper and the circulating track 2 also facilitates replacement of the hopper at any time.

[0033] When the hoppers are arranged in sequence, a gap is left between the adjacent two hoppers to avoid interference with the subsequent sensor sensing whether there are empty rubber plates in the current hopper.

[0034] A circulating driving assembly 3 comprises a rotating driving machine 31, a driving gear 32 and a driven gear 33. The circulating track 2 is wound around the outer periphery of the driving gear 32 and the driven gear 33 and is in mesh with them. The rotating driving machine 31 can drive the circulating track 2 to rotate, so that the plurality of hoppers ascend or descend relative to the hopper mounting frame 1. When the rotating driving machine 31 drives the driving gear 32 to rotate, it can drive the circulating track 2 in mesh with it to rotate, thereby providing power for the ascent or descent of the hopper thereon.

[0035] The induction assembly 9 is installed on the hopper mounting frame 1, and the induction assembly 9 comprises an inductor corresponding to the position of the hopper at the empty plate taking position of the rubber plate, so as to induct whether there is an empty plate in the hopper at the taking position. Specifically, the inductor corresponds to the position of the bottommost empty plate at the empty plate taking position of the rubber plate, and can induct whether there is an empty plate in the height range of the position, so as to determine whether there is an empty plate in the hopper and whether the next hopper needs to be replaced. That is, through the induction of the inductor, the cooperation of the circulating track 2 and the circulating driving assembly 3, it can be inducted whether there is an empty plate in the hopper, and the automatic feeding of the empty plate of the ping-pong paddle is realized, and the feeding efficiency of the empty plate is improved.

[0036] Specifically, the inductor is electrically connected with the rotating driving motor 31, and when the inductor senses that there is no empty plate at the height position, a signal will be transmitted to the rotating driving motor, and at this time, the rotating driving motor starts to work to drive the driving gear 32 to rotate, and the circulating track 2 can drive the hopper full of empty plates to move upward by one carrier position, and when the inductor senses that there is an empty plate in the hopper, the next station will automatically grab the empty plate in the hopper. At the same time, the original hopper will descend by one carrier position under the rotation of the rotating track.

[0037] It should be noted that the type of inductor is not limited, which can be a sensor, as long as it can induct whether there is an empty plate at the bottom of the hopper.

The two circulating tracks 2 are driven by the transmission shaft 4, so that the synchronous rotation of the two circulating tracks 2 can be realized by one rotary driving machine 31.

[0046] In some embodiments, the rotary driving machine 31 can be a speed reducer or a driving motor, and is not limited to the above two kinds, as long as it is a known mechanical structure capable of driving the transmission shaft 4.

[0047] The guiding member 8 is arranged on the hopper mounting frame 1 corresponding to the position of the circulating track 2, and two chain guiding grooves 81 parallel to each other are arranged on the two sides of the guiding member 8 in the length direction and in the height direction, respectively.
