[0034] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0035] 1. The utility model provides a bagging packaging machine suitable for triangular cakes. The prefabricated bags are placed on a bag storage device, and a bag taking device transfers the prefabricated bags from the bag storage device to a bag opening device; a bag pushing device pushes the materials into the opened prefabricated bags on the bag opening device, and a bag clamping device cooperates with a bag pushing device to push the prefabricated bags containing the materials to a bag pressing turntable device, and the bag pushing device withdraws from the bag opening, and a bag pressing turntable device and a bag taking device cooperate to realize tensioning of the bag opening of the prefabricated bags and then vacuumizing with negative pressure to form the prefabricated bags, and the bag pushing device returns to its original state position; a bag clamping device tightens the bag opening, a bag pressing turntable device presses the bag opening, and a bag clamping device returns to its original state position, and a bag pressing turntable device presses the prefabricated bags with the bag opening flattened; a bag pressing turntable device sends the pressed prefabricated bags to a knife sealing station, and a knife sealing device seals the prefabricated bags flat, and the bag pressing turntable device returns to its original state; the utility model can effectively solve the bagging work for special-shaped prefabricated bags.

[0036] 2. The utility model provides a bagging packaging machine suitable for triangular cakes. When the push head pushes the material into the prefabricated bag, the push head withdraws from the prefabricated bag, and at the same time, the bag pushing drive assembly drives the vacuum tube to extend outward from the outer end face of the push head, so that the vacuum tube stays in the prefabricated bag. At this time, the prefabricated bag is formed by the negative pressure vacuuming through the tension of the bag mouth of the prefabricated bag with the other parts of the vacuum bagging machine, such as the bag clamping device. After the action is completed, the vacuum tube retracts to its original state. In this process, since the push head has completed the positioning work when pushing the material, the relative position relationship between the push head and the prefabricated bag has been determined. When the vacuum tube is working, it extends out of the outer end face of the push head, so it does not need to be positioned again, eliminating the transportation and repeated positioning mechanism during vacuuming, and the structure is simpler. In addition, the overall working efficiency of the vacuum bagging machine is also improved.

[0037] 3. The utility model provides a bagging packaging machine suitable for triangular cakes, and a bag pushing through hole is arranged on the outer end surface, so as to further limit and locate the position of the vacuum tube, improve the position accuracy of the vacuum tube when working, and when vacuuming is not needed, the vacuum tube will retract into the first bag pushing accommodating chamber, so as to have a better dustproof effect, and the travel distance of the vacuum tube is shorter, and the movement of the vacuum tube is more stable; the arrangement of the bag pushing limit device can further limit the position of the vacuum tube, and ensure the stability of the vacuum tube during reciprocating motion; the bag pushing drive assembly and the vacuum tube can reciprocate together with the pushing rod, so as to reduce the travel distance of the vacuum tube driven by the bag pushing drive assembly to reciprocate, and the structure is more stable.

[0038] 4. The utility model provides a bagging packaging machine suitable for triangular cakes, in which a bag pushing driving assembly is arranged on a bag pushing slide, so as to better arrange the positions of the bag pushing driving assembly and the vacuum tube; a bag pushing rack is slidably connected to the bag pushing slide, so as to improve the stability of the reciprocating movement of the bag pushing rack; a pushing rod is slidably connected to the vacuum tube, so as to further improve the stability of the reciprocating movement of the vacuum tube; a second bag pushing accommodating chamber is provided in the pushing rod for placing the vacuum tube, so as to better arrange the positions of various components; the cooperation between the bag pushing limit groove and the bag pushing limit block can better limit the farthest distance of the bag pushing rack movement, and play a good limiting role.

[0039] Fifth, the utility model provides a bagging packaging machine suitable for triangular cakes. When the bag needs to be opened, the first bag taking driving assembly and the second bag opening assembly are driven by the second bag taking driving assembly to move linearly in the direction close to the first bag opening assembly until the vacuum suction cups on the first bag opening assembly and the second bag opening assembly press and adsorb the prefabricated bag. At this time, the first bag taking driving assembly drives the second bag opening assembly to swing, so that the prefabricated bag is opened. Since the bag opening method is completed by the action of the second bag opening assembly, the first bag opening assembly is fixed, which can well solve the problem that the synchronization of the first bag opening assembly and the second bag opening assembly in the prior art is difficult to unify. And because the vacuum suction cup just adsorbs the prefabricated bag, the first bag opening assembly and the second bag opening assembly are driven by the second bag taking driving assembly to approach each other. At this time, the second bag opening assembly has not swung yet, and the vacuum suction cup has a better effect of adsorbing the prefabricated bag. When the adsorption is completed and the bag needs to be opened, the bag is opened by the swinging method of the second bag opening assembly, and the bag mouth can be opened in an arc form, with a good bag opening effect, which is more suitable for opening special-shaped prefabricated bags for packaging triangular cakes or sandwiches.

[0040] 6. The utility model provides a bagging packaging machine suitable for triangular cakes. The bag taking sliding block is slidably connected to the first bag taking sliding rail, which can better limit the moving direction of the bag taking sliding block, and the first bag taking sliding rail can also play a good supporting role for the bag taking sliding block; the bag taking limiting piece is arranged to limit the farthest moving distance of the bag taking sliding block, so that in the initial state, the position of the vacuum suction cup in the second bag opening component can be better controlled, so that the adsorption surface of the vacuum suction cup matches the plane of the prefabricated bag, which can better adsorb the prefabricated bag and improve the adsorption effect; the arrangement of the second bag taking sliding rail plays a good supporting and limiting role, which is convenient for improving the structural stability of the entire bag opening device.

[0041] 6. The utility model provides a bagging packaging machine suitable for triangular cakes. When bag clamping is required, the first bag clamping driving mechanism drives the second bag clamping driving mechanism and the rotating bag clamping assembly to move to the bag opening device, and the second bag clamping driving mechanism drives the two rotating bag clamping assemblies to move toward each other, and the bag clamping mechanism clamps the side bag edges of the prefabricated bag; the rotating bag clamping assembly moves to the bag pressing turntable device together with the bag pushing device, the bag pushing device withdraws from the bag mouth, the bag pressing plate is pressed, the bag clamping rotating mechanism drives the bag clamping mechanism to rotate to a rotating state, and the bag clamping mechanism tightens the bag mouth of the prefabricated bag to both sides, and when the bag pressing device presses the bag mouth, the bag clamping mechanism is released, and the first bag clamping driving mechanism drives the second bag clamping driving mechanism and the rotating bag clamping assembly to move to the bag opening device to complete the entire bag clamping work.

[0042] 7. The utility model provides a bagging packaging machine suitable for triangular cakes, in which the bag clamping rotating motor drives the bag clamping mounting seat to rotate through the bag clamping reducer, thereby driving the finger cylinder on the bag clamping mounting seat to rotate; the first bag clamping driving motor drives the bag clamping synchronous belt to rotate, thereby driving the bag clamping synchronous belt fixing block to move, so that the second bag clamping driving mechanism and the rotating bag clamping assembly arranged on the second bag clamping driving mechanism make reciprocating motion on the slide rail; the second bag clamping driving motor drives the bag clamping slider to move through the chain, so that the two rotating bag clamping assemblies make reciprocating motion on the bag clamping chain; the provision of the first bag clamping slide rail, the second bag clamping slide rail and the third bag clamping slide rail play a good supporting and limiting role, which is convenient for improving the structural stability of the entire bag clamping device.

[0090] When the device is working, the materials to be packaged are placed on the front-end production line conveyor docking, and the packaged materials are conveyed to the single-turn tail rack. The front end of the single-turn conveyor is provided with an induction electric eye to prepare the pushing device 100 for the pushing work. At the same time, the triangular prefabricated bags in the bag storage device 300 are pulled down by the bag taking mechanism. At this time, the suction cup on the bag taking device 400 generates negative pressure through the vacuum generator. At this time, the bag opening servo motor of the bag component works and the bag opening cylinder drives the connecting rod to move the prefabricated bag sucked by the suction cup to the predetermined position of the bag opening station. The bag opening component moves forward and puts the prefabricated bag on the claw component. The spring on the bag opening component stretches the bag opening mold through the tension to open and tighten the bag. At this time, the bag opening turntable device is driven by the bag opening servo motor to rotate the opened bag 90 degrees, and the bag opening induction electric eye is used to detect the presence (absence) of the bag, and then rotates 90 degrees to the bag pushing station.At the same time, the bag taking device 400 returns to the bagging station and puts the next bag on the claw opening component; if a bag is detected on the bag pushing station, the bag pushing device 100 works to push the material into the prefabricated bag that has been opened by the claw opening component; if no bag is detected on the bag pushing station, the bag pushing component does not work, and the bag opening device 200 continues to rotate 90 degrees until it detects that there is a bag on the claw opening component of the bag pushing station, and the bag pushing station starts pushing the bag; at the same time, when the electric eye detects that the material of the single-turn tail rack has reached the sensing position, the bag pushing device 100 starts to work, and pushes the bag The bag servo motor drives the bag pushing synchronous belt to drive the bag pushing component, so that the bag pushing component moves forward and backward to push the material into the prefabricated bag on the bag opening device 200.

At this time, the bag pushing device 100 cooperates with the bag clamping device 500 to tighten the bag mouth of the prefabricated bag to perform negative pressure vacuuming to form the prefabricated bag. After completing the action, the bag pushing device 100 returns to the original state position; at this time, the bag clamping rotating motor 541 is activated to The bag clamping finger cylinder rotates to the rotating state, and the bag clamping cylinder pulls the chain by the second bag clamping drive motor 522 to make the bag clamping finger cylinder tighten the bag opening to both sides. After the bag pressing device presses the bag opening, the bag clamping finger cylinder is loosened, and the bag clamping device 500 returns to the original state position. At this time, after the bag pressing turntable device 600 flattens the bag opening, the bag pressing servo lifting mechanism starts to work to press the prefabricated bag, and then the bag pressing rotary mechanism works to send the material to the sealing device, and the knife sealing device 700 starts to work to seal the prefabricated bag flat, and the bag pressing rotary mechanism returns to the original state position. When the prefabricated bag is fed to the knife sealing device 700 through the pressing plate rotary mechanism of the bag pressing turntable device 600, it is automatically sent to the discharge bag folding tail frame. After sealing, the action is completed and all actions return to zero, completing the action of the whole machine. Repeat the above process to complete the continuous packaging work.
