Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to the technical field of bagging packaging machines, and more specifically to a sealing device and a bagging packaging machine. Background Art

[0002] Bagging machine is a machine that uses pre-made packaging bags to package materials. It is completed by putting the bag on the material, or it is a packaging machine that puts the material into the bag.

[0003] The existing bagging packaging machine needs to seal the opening of the bag after putting the material into the pre-made bag or putting the pre-made bag on the material. The operating principle of the existing bagging machine is: the bag suction mechanism sucks the pre-made bag from the bag storage, puts it on the bag opening mechanism, and then the material pushing mechanism pushes the material from the bag opening mechanism into the bag, and then continues to push it to the sealing mechanism for sealing.

[0004] For example, the authorization announcement date is December 3, 2021, the authorization announcement number is CN214986499U, and the utility model patent is named "A sealing device for a bagging machine". The utility model patent includes a bag mouth sorting mechanism, a bag mouth clamping mechanism, a packaging bag conveying mechanism and a heat sealing mechanism. The packaging bag conveying mechanism is a turntable structure for rotating and conveying packaging bags containing materials; the bag mouth sorting mechanism and the heat sealing mechanism are both fixedly arranged on the circumferential side of the packaging bag conveying mechanism, and the bag mouth sorting mechanism sorts the bag mouth of the packaging bag on the packaging bag conveying mechanism, and the bag mouth clamping mechanism clamps the bag mouth sorted by the bag mouth sorting mechanism, and rotates with the packaging bag conveying mechanism to place the sorted bag mouth of the packaging bag in the heat sealing mechanism for heat sealing. In this utility model patent, the packaging bag conveying mechanism is a rotatable turntable structure. When the bag clamping mechanism clamps the packaging bag and moves it to the heat sealing mechanism, the packaging bag conveying mechanism and the bag clamping mechanism rotate synchronously. The turntable of the packaging bag conveying mechanism carries the packaging bag containing materials located above it, and together with the bag clamping mechanism, rotates the packaging bag to a position where it docks with the heat sealing mechanism. The heat sealing mechanism heat-seals it. After the heat sealing is completed, the turntable of the packaging bag conveying mechanism continues to rotate to move the packaging bag to the discharge station.

[0005] The sealing device for the bagging machine in the above-mentioned prior art has a complex structure and high equipment cost because the turntable needs to move synchronously with the bag clamping mechanism and the turntable needs to be driven by a driving mechanism. When the turntable drives the sealed packaging bags to move to the discharging station, a pushing mechanism is also required to push the sealed packaging bags onto the output belt, which also increases the cost of the equipment.

[0006] In order to overcome the defects and deficiencies existing in the above-mentioned prior art, the present utility model provides a sealing device and a bagging packaging machine. The invention object of the present utility model is to provide a new sealing device, which can reduce the structural complexity and equipment cost of the sealing device used in the existing bagging packaging machine without affecting the sealing efficiency. The sealing device of the present utility model includes a material receiving platform, a bag mouth clamping mechanism and an output mechanism. The material receiving platform is used to receive the packaging bags filled with materials. The output mechanism is docked with the material receiving platform. The bag mouth clamping mechanism clamps the bag mouth of the packaging bag and drives the packaging bag to rotate by a set angle to transfer the packaging bag on the material receiving platform to the output mechanism. Compared with the prior art, the present utility model changes the original rotatable turntable structure to a fixed material receiving platform and changes the position of the output mechanism, so that the bag mouth clamping mechanism can directly transfer the packaging bag to the output mechanism, and thus the driving of the turntable structure and the pushing mechanism can be cancelled, reducing the structural complexity of the sealing device and its equipment cost.

[0018] Compared with the prior art, the beneficial technical effects brought by the present utility model are as follows:

[0019] 1. The present utility model changes the turntable structure in the existing sealing device to a material receiving platform structure, cancels the driving structure of the turntable, simplifies the structure of the sealing device for the bagging machine, and saves the equipment cost. At the same time, the present utility model docks the output mechanism of the existing sealing device with the material receiving platform and the bag clamping mouth mechanism, so that the packaging bags clamped by the bag clamping mouth mechanism can be directly transferred to the output mechanism, and can be directly output or output after heat sealing. Compared with the existing sealing device, the pusher mechanism for pushing the packaged bags after sealing from the turntable to the output mechanism is further omitted, further simplifying the equipment structure and saving the equipment cost.

[0020] 2. The present utility model relies on the bag clamping mouth mechanism to realize the movement of the packaging bag between the bag receiving station and the output mechanism. Through the docking of the output mechanism and the material receiving platform, the displacement of the bag clamping mouth mechanism for transporting the packaging bag is limited, and its sealing and output efficiency is the same as that of the existing sealing device.

[0021] 3. The present utility model can also be applicable to the output of non-sealed packaging bags. The bag clamping mouth mechanism transfers the packaging bags filled with the material from the bag receiving station of the material receiving platform to the output mechanism. When it is necessary to seal the packaging bags, the heat sealing mechanism arranged on one side of the output mechanism can be used to heat seal the bag mouth of the packaging bags. When no sealing is required, the output mechanism can directly output. When there are requirements for the sealing shape, for example, the bag mouth of the packaging bag needs to be folded and sealed, a corresponding sealing mechanism can be arranged on one side of the output mechanism for corresponding sealing, so that the sealing form of the sealing device is variable and has the characteristics of diversification.

[0022] 4. The utility model is provided with a fixed baffle and a telescopic baffle at the bag receiving station, which can limit the posture of the packaging bag entering the material receiving platform, ensure the neatness when the bag mouth clamping mechanism clamps the bag mouth of the packaging bag, and avoid the skew of the packaging bag. An end baffle is further provided, which can change the size of the bag receiving station according to the size of the material and the size of the packaging bag, so as to ensure the posture of the packaging bag entering the material receiving platform. When the bag mouth clamping mechanism transports the packaging bag, the telescopic baffle retracts under the material receiving platform, so that the bag mouth clamping mechanism can smoothly transport the packaging bag to the output mechanism.

[0029] Refer to the attached drawings of the specification Figure 1As shown in the figure, this embodiment discloses a sealing device 34, which includes a material receiving platform 1, a bag mouth clamping mechanism 2, and an output mechanism 3.

The bag mouth clamping mechanism 2 is configured to clamp the bag mouth of the packaging bag located on the material receiving platform 1 and drive the packaging bag to move along a set arc trajectory out of the material receiving platform 1. The input end of the output mechanism 3 is docked with the material receiving platform 1. The bag mouth clamping mechanism 2 clamps the bag mouth of the packaging bag on the material receiving platform 1, rotates along the set arc trajectory, and then transfers the packaging bag to the output mechanism 3. And the bag mouth of the packaging bag transferred to the output mechanism 3 faces the side of the conveying direction of the output mechanism 3.

[0030] In this embodiment, the turntable structure in the existing sealing device is changed to the structure of the material receiving platform 1, the driving structure of the turntable is cancelled, the structure of the sealing device 34 for the bagging machine is simplified, and the equipment cost is saved. At the same time, in the present utility model, the output mechanism 3 of the existing sealing device is docked with the material receiving platform 1 and the bag mouth clamping mechanism 2, so that the packaging bag clamped by the bag mouth clamping mechanism 2 can be directly transferred to the output mechanism 3, and can be directly output or output after heat sealing. Compared with the existing sealing device, the pusher mechanism for pushing the packaged bag with the seal completed from the turntable to the output mechanism 3 is further omitted, the equipment structure is further simplified, and the equipment cost is saved.

[0031] In this embodiment, the above-mentioned sealing device 34 is applicable to the output of non-sealed packaging bags. When no sealing is required, the output mechanism 3 can directly output.

[0032] As an example of this embodiment, refer to the attached drawings of the specification Figure 2 and attached Figure 3 As shown, when it is necessary to seal the packaging bag, a heat sealing mechanism 9 is provided on one side of the output mechanism 3. When the bag mouth clamping mechanism 2 rotates to the position where it clamps and transfers the packaging bag to the output mechanism 3, the bag mouth of the packaging bag is docked with the heat sealing mechanism 9, and the heat sealing mechanism 9 performs heat sealing on the bag mouth of the packaging bag.

[0034] Through the above examples, it can be seen that the sealing form of the sealing device 34 mentioned in this embodiment is variable, with the characteristic of diversified sealing, and can meet various sealing packaging specifications.

[0036] In this embodiment, by providing the fixed baffle 5 and the telescopic baffle 6 at the bag receiving station 4, the posture of the packaging bags entering the material receiving platform 1 can be limited, ensuring the neatness when the bag mouth clamping mechanism 2 clamps the bag mouths of the packaging bags and avoiding the packaging bags from being skewed. When the bag mouth clamping mechanism 2 transfers the packaging bags, the telescopic baffle 6 retracts below the material receiving platform 1, enabling the bag mouth clamping mechanism 2 to smoothly transfer the packaging bags onto the output mechanism 3.

[0037] As an example of this embodiment, an end baffle 7 for limiting the length of the packaging bags entering the bag receiving station 4 is provided at the rear end of the bag receiving station 4. By further providing the end baffle 7, the size of the bag receiving station 4 can be changed according to the size of the materials and the size of the packaging bags, ensuring the posture of the packaging bags entering the material receiving platform 1.
