[0029] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0030] like Figure 1-6 As shown, an automatic stacking device for biscuit packaging includes a frame 1. A straight opening 101 is provided on the top outer surface of the frame 1. A conveyor belt 102 is rotatably connected to the inner side of the straight opening 101. A support plate 103 is fixed to the rear end of the left outer wall of the frame 1. A connecting rod 104 is rotatably mounted on the right end of the front outer wall of the support plate 103. A hollow rotating rod 105 is fixed to the front outer wall of the connecting rod 104. A receiving square plate 106 arranged in a circular array is fixed to the outer peripheral side wall of the hollow rotating rod 105. A through-type straight groove 107 arranged in a circular array is provided on the outer peripheral side wall of the hollow rotating rod 105 between several receiving square plates 106. A limit component 2 is provided inside the hollow rotating rod 105. The limit component 2 includes a bidirectional wire rotatably mounted inside the hollow rotating rod 105. The two ends of the outer surface of the double-acting screw 201 are threaded with round sleeves 202. The outer sidewalls of the two round sleeves 202 are fixed with connecting bars 203 arranged in a circular array. The opposite ends of several connecting bars 203 extend along the straight groove 107 to the outside of the hollow rotating rod 105 and are fixed with clamping plates 204. One end of the double-acting screw 201 extends to the front outer wall of the hollow rotating rod 105 and is fixed with positioning plates 205 and knobs 206 respectively. The outer side wall of the positioning plate 205 is threaded to the hollow rotating rod 105 by positioning screws 207. The rear outer wall of the support plate 103 is fixedly installed with a drive motor 4. One end of the connecting rod 104 extends to the rear outer wall of the support plate 103 and is fixedly connected to the output end of the drive motor 4.

[0031] In the above embodiment, during actual use, the knob 206 is first turned to drive the bidirectional lead screw 201 to rotate according to the required size of the stacked biscuits. This drives the circular sleeve 202 to move the connecting rod 203 relative to each other on the inner side of the straight groove 107, moving it away from or closer to each other. This, in turn, causes the clamping plate 204 to move relative to each other among several receiving square plates 106. After moving to the appropriate position, the positioning screw 207 is turned to fix the positioning plate 205 to the hollow rotating rod 105 to prevent the bidirectional lead screw 201 from spinning. Then, the biscuits are sequentially conveyed to the end of the conveyor belt 102, and the drive motor 4 is started to drive the connecting rod. 104 drives the hollow rotating rod 105 to rotate, causing the biscuits conveyed to the end of the conveyor belt 102 to fall sequentially onto the receiving tray 106. (Since the diameter of the straight groove 107 is much smaller than the diameter of the biscuits to be stacked, the biscuits can be prevented from falling into the straight groove 107. Furthermore, since the straight groove 107 is through-type, when biscuit crumbs fall into the hollow rotating rod 105 along the straight groove 107, they can be discharged along the straight groove 107 during rotation.) With the assistance of two clamping plates 204, biscuits of different sizes are positioned to prevent displacement during rotation, which would affect the efficiency of subsequent stacking and thus improve practicality.

[0032] An inclined square plate 108 is fixed to the left end of the front outer wall of the support plate 103 and below the receiving square plate 106. An inclined guide square plate 109 is fixed to the front outer wall of the support plate 103 and between the square plate 108 and the receiving square plate 106. A limiting component 2 3 is provided on the outer top surface of the square plate 108. The limiting component 2 3 includes symmetrically opened through transverse grooves 301 on the outer top surface of the square plate 108. Connecting bars 2 302 are slidably connected inside the two transverse grooves 301. One end of the two connecting bars 2 302 extends to the outer top surface of the square plate 108 and is fixed with a clamping plate 2 303, while the other end extends to the outer bottom surface of the square plate 108 and is fixed with a slider 304. A slider 304 is symmetrically fixed to the outer bottom surface of the square plate 108. Mounting blocks 305, two mounting blocks 305 are rotatably connected to the outer walls of their corresponding sides by a double-acting lead screw 306, two sliders 304 are threaded onto the two ends of the outer circumferential surface of the double-acting lead screw 306, one end of the double-acting lead screw 306 extends to the outer wall of one of the mounting blocks 305 and is externally fixedly mounted with a gear 307, an electric push rod 308 is fixedly mounted on the outer bottom surface of the square plate 108, a connecting block 309 is fixedly mounted on the output end of the electric push rod 308, a rack 310 is fixedly mounted on the outer wall of the connecting block 309, the rack 310 and the gear 307 are meshed, an electric push rod 5 is fixedly mounted on the outer top surface of the square plate 108, and a push plate 501 is fixedly mounted on the output end of the electric push rod 5.

[0033] After the biscuit on the receiving tray 106 rotates 180 degrees counterclockwise from the end of the conveyor belt 102, the biscuit comes into contact with the top of the guide tray 109. The receiving tray 106 continues to rotate counterclockwise, causing the biscuit to slide down the guide tray 109 onto the outer top of the square plate 108. Then, the electric push rod 5 is activated to extend the rack 310, which in turn drives the gear 307 to rotate the double-acting screw 306. This causes the slider 304, along with the connecting bar 302, to move relative to each other on the outer circumferential surface of the double-acting screw 306, moving away from or closer to each other. This allows the clamping plate 303 to position and correct the sides of the biscuit, preventing misalignment during stacking and ensuring the stacking effect. Afterward, the electric push rod 5 is activated to retract the push plate 501, causing the biscuit to retract as needed. This cycle is repeated to stack the biscuits as required. Finally, the stacked biscuits are removed.

[0034] The working principle of this utility is as follows: When in use, first turn the knob 206 according to the size of the biscuit to drive the bidirectional lead screw 201 to rotate, which pushes the round sleeve 202 to drive the connecting strip 203 to move relative to each other inside the straight groove 107, thereby moving the clamping plate 204 to the appropriate position between the receiving plates 106.

[0035] Simultaneously, the drive motor 4 is started to drive the connecting rod 104 to carry the hollow rotating rod 105 in a circular motion, and then the conveyor belt 102 is started to transfer the biscuit to the receiving tray 106.

[0036] Meanwhile, after the receiving plate 106 rotates the biscuit 180 degrees counterclockwise, the biscuit first comes into contact with the top of the guide plate 109. Then, the receiving plate 106 continues to rotate counterclockwise, causing the biscuit to slide down the guide plate 109 to the outer top surface of the plate 108 and come into contact with the push plate 501.

[0037] Next, the electric push rod 25 is activated, which drives the rack 310 to extend, causing the gear 307 to rotate the double-acting lead screw 2 306. This allows the slider 304, along with the connecting bar 2 302, to move relative to the outer surface of the double-acting lead screw 2 306, allowing the clamping plate 2 303 to position and correct the two sides of the biscuit.

[0038] Finally, the electric push rod 25 is activated to drive the push plate 501 to retract, causing the biscuit to retract as well. This process is repeated to stack the biscuits.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
