[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. When the present invention is working, the first servo motor drives the feeding screw to rotate forward, thereby driving the screw nut to push the sugar blocks forward, and the sugar blocks arranged in the candy silo are pushed into the packaging position in sequence. Under the action of the sugar blocking plate, the sugar blocks fall into the packaging paper formed by the packaging paper former, and then the formed packaging paper is heat-sealed and cut in sequence in the side heat-sealing mechanism and the end sealing and cutting mechanism to realize the packaging of the sugar blocks. After completing the conveying of a row of candies, the first servo motor then drives the feeding screw to reverse, thereby driving the screw nut to push the sugar blocks backward to contact the silo power slider, and driving the silo power slider to continue to retreat together, and under the action of the silo power slider, the spiral pair is driven to rotate, and the rotating spiral pair drives the silo power shaft to rotate, and the rotating silo power shaft belt rotates through the power gear, and the rotating gear drives the candy silo to advance a certain distance by meshing with the rack, and then the candy packaging operation of the next row is carried out. This process can be repeated to continuously complete the packaging of all candies in the candy silo.

[0015] 2. In the present invention, when the end sealing and cutting mechanism seals and cuts the packaged candies, the second servo motor drives the first crankshaft connecting rod and the second crankshaft connecting rod to move simultaneously through the crankshaft, and the moving first crankshaft connecting rod and the second crankshaft connecting rod simultaneously drive the outer slider and the inner slider to move, and the first heating cutter on the moving inner slider and the second heating cutter on the outer slider are used to seal and cut the packaged candies, wherein spring buffer components are respectively provided between the first heating cutter and the inner slider and between the second heating cutter and the outer slider to play a buffering role.

[0016] 3. In the present invention, the side heat sealing mechanism and the end sealing and cutting mechanism are connected by a synchronous linkage mechanism. When the second servo motor drives the first crankshaft connecting rod to move through the crankshaft, the moving first crankshaft connecting rod drives the connecting block to move back and forth, and the moving connecting block drives the triangular transmission member to rotate back and forth. The triangular transmission member that rotates back and forth drives the double-sided rack to move up and down, and the double-sided rack that moves up and down drives the packaging paper conveying wheel and the side heat sealing wheel to rotate through the transmission gear, wherein the packaging paper conveying wheel and the side heat sealing wheel perform intermittent movement under the action of the one-way bearing to side-seal the packaging paper. The synchronous linkage mechanism is used to connect the side heat sealing mechanism and the end sealing and cutting mechanism to move at the same time, thereby ensuring the synchronization and continuity of the packaging work and reducing energy loss.

[0017] 4. A crank slider pushing mechanism is also provided on the top of the main body of the packaging machine frame of the present invention. The crank slider pushing mechanism includes a second rotating shaft arranged above the bin material support plate. The second rotating shaft is provided with a crank at the end away from the bin power slider. The bin material support plate is provided with a slider push rod cooperating with the crank through a push rod guide. The end of the slider push rod extends into the inner cavity of the sugar blocking plate. The second rotating shaft is transmission-connected to the first servo motor. The second rotating shaft is driven to rotate by the first servo motor, and the second rotating shaft drives the crank to rotate. The rotating crank drives the slider push rod to move up and down along the push rod guide to push the sugar cubes to prevent the sugar cubes from getting stuck at the packaging entrance.

[0018] 5. The power gear described in the present invention is connected to the bin material power shaft via a one-way bearing. The bin material power slider and the end away from the candy bin are provided with a reset spring. Under the action of the reset spring, the bin material power slider is reset. Since the power gear is connected to the bin material power shaft via a one-way bearing, when the bin material power slider is reset, the bin material power shaft will not drive the power gear to rotate.

[0019] 6. The candy silo described in the present invention includes a bottom plate, a front baffle is provided at the front end of the bottom plate, sockets are provided on both sides of the front baffle, outer plates are plugged into the sockets, and the outer plates on both sides can slide freely. After the candy silo is placed in the machine, the outer plates on both sides need to be pulled out to avoid obstruction of the movement of the sugar blocks and the lead screw nut pushing the sugar blocks during the feeding process.

During operation, the first servo motor 19 drives the feeding screw 10 to rotate forward, thereby driving the screw nut to push the sugar blocks 11 forward, and the sugar blocks arranged in the candy silo 6 are pushed into the packaging position in sequence. Under the action of the sugar blocking plate 17, the sugar blocks fall into the packaging paper formed by the packaging paper former 18, and then the formed packaging paper is heat-sealed and cut in sequence in the side heat-sealing mechanism 20 and the end sealing and cutting mechanism 21 to realize the packaging of the sugar blocks.

[0033] like Figure 4As shown, the side heat sealing mechanism 20 and the end sealing and cutting mechanism 21 are connected by a synchronous linkage mechanism. The synchronous transmission mechanism includes a double-sided rack 34 vertically arranged between the packaging paper conveying wheel 22 and the side heat sealing wheel 23. The packaging paper conveying wheel 22 and the side heat sealing wheel 23 are provided with a transmission gear 35 meshing with the double-sided rack 34; the slide rail 39 is provided with a support member 36, and the support member 36 is provided with a triangular transmission member 38 via a first rotating shaft 37. One end of the triangular transmission member 38 is hinged to the double-sided rack 34, one end of the triangular transmission member 38 is hinged to the connecting block 33, and the other end of the triangular transmission member 38 is connected to the first rotating shaft 37. In the present invention, the side heat sealing mechanism 20 and the end sealing and cutting mechanism 21 are connected by a synchronous linkage mechanism. When the second servo motor 29 drives the first crankshaft connecting rod 31 to move through the crankshaft 30, the moving first crankshaft connecting rod 31 drives the connecting block 33 to move back and forth, and the moving connecting block 33 drives the triangular transmission member 38 to rotate back and forth. The triangular transmission member 38 that rotates back and forth drives the double-sided rack 34 to move up and down.
