The dispenser 1 includes an egg tray clamping assembly 300, a liftable gripping assembly 401, and an egg tray output assembly 100 arranged sequentially from top to bottom. The egg tray clamping assembly clamps the stacked egg trays from the left and right sides. The liftable gripping assembly sequentially separates the bottommost egg tray and moves it downward to the egg tray output assembly. The egg tray output assembly transports the egg tray from back to front. In this power mechanism, the egg tray clamping assembly 300 is driven by the clamping cam drive 2 to clamp or release stacked egg trays from the left and right sides; the liftable gripping assembly 401 is driven to rise and fall by the lifting cam drive 3 to move the separated egg trays downwards; the cam of the clamping cam drive 2 and the cam of the lifting cam drive 3 are coaxially mounted on the same power drive shaft 4, and the cam of the clamping cam drive and the cam of the lifting cam drive rotate coaxially; the power drive shaft 4 is also connected to the power input end of the egg tray output assembly 100 via a transmission component, that is: one power drive shaft provides power to the egg tray clamping assembly, the liftable gripping assembly and the egg tray output assembly at the same time.

[0038] In this embodiment, the egg tray clamping member 301 includes a pair of egg tray clamping plates 303 distributed on the left and right. The egg tray clamping plates 303 are arranged vertically. The pair of egg tray clamping plates 303 can swing towards each other or away from each other in the left and right directions to clamp or loosen the stacked egg trays. The egg tray support member 302 includes a pair of support pin groups 304 distributed on the left and right. The pair of support pin groups 304 can move from the left and right directions to contact the bottom of the upper edge of the lowest egg tray to support the egg tray.

[0039] In this embodiment, the clamping cam drive member 2 includes a first cam 7 and a first cam follower mounted on the power drive shaft. A first cam track 308 is provided on the right side of the first cam 7. The first cam follower cooperates with the first cam track 308. The first cam follower is connected to a pair of left and right distributed first pull rods 309. The first cam follower drives the pair of first pull rods 309 to move up and down. The pair of first pull rods 309 are respectively connected to a pair of egg tray clamping plates 303 to pull the pair of egg tray clamping plates 303 to swing in opposite directions or in opposite directions.

[0040] In this embodiment, the egg tray clamping component 301 further includes a pair of longitudinal support shafts 305 distributed on the left and right sides of a pair of egg tray clamping plates 301. A swing rod 306 is rotatably sleeved on the outer side of the longitudinal support shaft 305. The swing rod is rotatably engaged with the longitudinal support shaft.

The upper end of the first pull rod 309 is hinged to the outer end of the swing rod 306 located on the same side. When the first pull rod 309 moves up and down, it will drive the swing rod 306 to rotate around the longitudinal support shaft. The swing rod 306 drives the egg tray clamping plate 303 to rotate synchronously.

[0041] In this embodiment, the first cam follower includes a swing drive shaft 310 laterally disposed in front of the lower end of a pair of first pull rods 309. The left and right ends of the swing drive shaft 310 are respectively fixed with first connecting rods 311. The first connecting rods 311 extend rearward and are hinged to the lower end of the first pull rods 309 located on the same side. In order to drive the swing drive shaft 310 to rotate, the right end of the swing drive shaft 310 is fixed with a second connecting rod 312 extending downward and rearward. The lower end of the second connecting rod 312 is provided with a first roller 313, which rolls with the first cam track 308. During operation, the first cam 7 rotates under the drive of the power drive shaft 4. Due to the rolling cooperation between the first roller 313 and the first cam track 308, the first cam track 308 drives the second connecting rod 312 to swing up and down during the rotation of the first cam track 308. The second connecting rod 312 drives the swing transmission shaft 310 to rotate. The swing transmission shaft 310 drives the two first connecting rods 311 to swing. When the two first connecting rods 311 swing up and down, they pull a pair of first pull rods 309 to move up and down. When the first pull rods 309 move up and down, they drive the swing rod 309 to rotate around the longitudinal support shaft 305. Finally, the swing rod drives the egg tray clamping plate to rotate, thereby realizing that a pair of egg tray clamping plates can loosen or clamp the stacked egg trays from the left and right directions.

[0042] In this embodiment, the first cam follower also includes a tension spring 314. The front end of the tension spring 314 hooks onto the lower end of the second link 312, and the rear end of the tension spring 314 hooks onto the spring hook rod 315 located behind the second link 312 and fixed to the pallet machine frame. The tension spring pulls the second link backward, so that the second link remains in its initial state when not in operation, and the tension spring pulls the second link to return to its original position after the second link swings.

[0043] In this embodiment, the support pin assembly 304 includes a pair of pin fixing blocks 316 distributed in front and rear. The pair of pin fixing blocks 316 are distributed on the front and rear sides of the egg tray clamping plate 301 located on the same side. Each pin fixing block 316 has several support pins 317 fixed on the inner side of its lower end, which are distributed longitudinally at intervals.

[0044] In this embodiment, the clamping cam drive 2 further includes a second cam track 318 and a second cam follower arranged around the outside of the first cam track 308. The second cam follower is connected to a second pull rod 321 and drives the second pull rod 321 to move up and down. The upper end of the second pull rod 321 is connected to a pair of support pin groups 304 via a linkage member, so as to pull the pair of support pin groups 304 to move from the left and right directions to contact the bottom of the upper edge of the lowest egg tray.

[0045] In this embodiment, the second cam follower includes a pair of left and right longitudinally arranged moving rods 319 and a transverse guide rod 320 horizontally arranged below the rear ends of the pair of moving rods 319. The support pin assembly 304 is fixedly arranged inside the moving rods 319 on the same side. Specifically, a pair of pin fixing blocks 316 of each support pin assembly 304 are installed on pin fixing seats 322 on the same side. The rear ends of the pair of moving rods 319 are respectively fixed with sliding sleeves 323 that slide in cooperation with the transverse guide rod 320. The upper end of the second pull rod 321 is connected by a linkage. The lower end of the second pull rod 321 is connected to the rear end of a longitudinally arranged cam connecting rod 324, which is connected to the sliding sleeve at the rear end of a pair of moving rods 319. The front end of the cam connecting rod 324 is rotatably connected to the frame of the palletizer, and the rotation axis of the cam connecting rod 324 is transverse. The cam connecting rod 324 is located on the right side of the second cam track 318, and a second roller 325 is provided on the left side of the cam connecting rod 324. The second roller 325 is in rolling engagement with the second cam track 318. When the second pull rod moves up and down, it drives the pair of moving rods to move in opposite directions or away from each other through the linkage. During operation, the second cam rotates under the drive of the power drive shaft. Since the second roller is in rolling engagement with the second cam track, the second cam track drives the second pull rod to move up and down through the second roller and the cam connecting rod during the rotation of the second cam track.

[0046] In this embodiment, the linkage includes a third link 326, a fourth link 327, a three-pronged joint 328, and a U-shaped seat 329.

The three-pronged joint 328 includes a first joint 3281 and a second joint distributed vertically. 3282 and a third connector 3283 extending to the left; the left end of the third connecting rod 326 is hinged to the sliding sleeve 323 at the rear end of the moving rod 319 on the right, and the right end of the third connecting rod 326 is hinged to the first connector 3281; the left end of the fourth connecting rod 327 is hinged to the sliding sleeve 323 at the rear end of the moving rod 319 on the left, and the right end of the fourth connecting rod 327 is hinged to the second connector 3282; the upper end of the second pull rod 321 is hinged to the third connector 3283. During operation, when the second pull rod moves up and down, it pulls the three-pronged connector to rotate. When the three-pronged connector rotates, it pulls the two sliding sleeves along the transverse guide rod to move towards or away from each other. The sliding sleeves drive the moving rod to move synchronously, and the support pins are installed on the moving rod, thereby realizing the linear movement of a pair of support pin assemblies towards or away from each other in the left-right direction.

[0047] In this embodiment, the liftable gripping component 401 has a pair of hooks 402 located on the left and right sides below the egg tray clamping component, and a drive shaft 403 for driving the hooks 402 to flip upward and hook onto the hollowed-out part on the lower periphery of the egg tray. Each hook 402 is driven to flip upward by a drive shaft 403.
