Description

Technical Field

[0001] The utility model relates to the technical field of potato chip packaging, and more specifically, to a nitrogen filling machine for potato chip packaging. Background Art

[0002] Filling nitrogen into potato chip cylinders is a common food packaging technology aimed at maintaining the freshness and taste of potato chips. Nitrogen is an inert gas that does not chemically react with food and does not support the growth of microorganisms. During the potato chip packaging process, nitrogen is used to replace the air inside the packaging, especially oxygen.

[0003] After retrieval, the patent with the application number CN202222779649.0 discloses a nitrogen filling machine for potato chip packaging, including a cylinder body. The top end of the front surface of the cylinder body is provided with a top plate, the bottom end of the front surface of the cylinder body is provided with a base, the bottom end of the top plate is provided with a sealing sleeve, and a feeding component is installed between the top plate and the base. The feeding component includes rotating grooves symmetrically formed on the top plate and the base near one side. In the utility model, a plurality of supporting platforms are arranged at equal angles on the outer side of the rotating shaft. After one supporting platform moves below the sealing sleeve, nitrogen is added to the potato chip cylinder on it, while other potato chips can be used for loading the potato chip cylinder, thereby prolonging the feeding time of the potato chip cylinder and facilitating use. Moreover, the rotation speed of the rotating shaft is stable, so that the nitrogen filling speed of the potato chip cylinder is more stable.

[0004] This structure drives multiple sets of supporting platforms loaded with potato chip cylinders to move synchronously through a motor. When the potato chip cylinder moves to the bottom of the sealing sleeve, it is jacked up by a push rod and the limit of the potato chip cylinder is realized. However, the supporting platform in this structure is not stable enough, and the potato chip cylinder needs to rotate continuously on the supporting platform, which easily causes the potato chip cylinder to fall off. At the same time, this structure requires more manual operation steps, affecting the nitrogen filling efficiency. Summary of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] Please refer to Figures 1 to 4 , in the present utility model, a nitrogen filling machine for potato chip packaging includes a processing frame 1 and a sealing sleeve 2 installed on its inner top wall. A synchronous shaft 3 is rotatably connected to the inner bottom wall of the processing frame 1. Uniformly distributed bearing seats 4 are slidably connected to the synchronous shaft 3. A driving motor 5 is fixedly installed at the bottom of the processing frame 1. The output shaft of the driving motor 5 penetrates the processing frame 1 and is installed at the bottom end of the synchronous shaft 3. A push rod 6 is fixedly installed at the bottom of the processing frame 1. The top end of the push rod 6 penetrates and extends into the interior of the processing frame 1. The top end of the push rod 6 is installed with a top plate 7. Installation grooves 8 are provided on the inner wall of the bearing seat 4. Two clamping plates 9 are slidably connected to the inner wall of the installation groove 8. Springs 10 are fixedly connected to the clamping plates 9. The other ends of the springs 10 are fixedly connected to the inner wall of the installation groove 8. An electromagnetic ring 11 is installed on the inner wall of the installation groove 8. Metal plates 12 are fixedly connected to the clamping plates 9. The metal plates 12 are magnetically connected to the electromagnetic ring 11. An infrared receiver 13 is installed on the outside of the bearing seat 4. An infrared emitter 14 is installed on the inner wall of the processing frame 1. A processor 15 is integrated on the inner wall of the processing frame 1. The infrared receiver 13, the push rod 6, the driving motor 5 and the electromagnetic ring 11 are all signal-connected to the processor 15.

[0023] Uniformly distributed guide grooves 16 are provided on the outside of the synchronous shaft 3. The bearing seats 4 are slidably connected to the inner walls of the guide grooves 16;

[0024] The bottom of the clamping plate 9 is fixedly connected with a slider 19, and the slider 19 is slidably connected with the inner wall of the installation groove 8.

[0025] In the initial state of the device, the electromagnetic ring 11 is in an energized state. The energized electromagnetic ring 11 generates magnetism to attract the metal plate 12, causing the clamping plate 9 to compress the spring 10 and enter the interior of the installation groove 8. At this time, the user places the potato chip tube from the top of the carrier seat 4, so that the bottom of the potato chip tube fits against the inner bottom wall of the carrier seat 4. Subsequently, the driving motor 5 drives multiple groups of carrier seats 4 loaded with potato chip tubes to rotate synchronously. When it rotates to the carrier seat 4 at the bottom of the sealing sleeve 2, the infrared receiver 13 on this carrier seat 4 receives the infrared rays emitted by the infrared emitter 14. The processor 15 controls the electromagnetic ring 11 to cut off the power supply and controls the push rod 6 to operate. The electromagnetic ring 11 loses magnetism after the power is cut off, and the spring 10 resets to push the clamping plate 9 into contact with the potato chip tube to complete clamping and limiting. Immediately afterwards, the push rod 6 drives the top plate 7 to move upward into contact with the carrier seat 4, and the carrier seat 4 starts to move upward along the guiding groove 16 until the top enters the sealing sleeve 2 to complete nitrogen filling and sealing. Subsequently, the push rod 6 drives the top plate 7 to move downward, and the carrier seat 4 under the action of gravity moves downward until it resets. At this time, the infrared receiver 13 of this group receives the infrared signal for the second time, and the processor 15 controls the electromagnetic ring 11 of this group to be energized and controls the driving motor 5 to operate. The electromagnetic ring 11 limits the clamping plate 9 again so that the potato chip tube is not restricted. The driving motor 5 drives the synchronous shaft 3 to rotate, so that the potato chip tube that has completed nitrogen filling moves to the back. The user can take out this potato chip tube and place an unfilled potato chip tube. At the same time, an unfilled potato chip tube will also enter the bottom of the sealing sleeve 2, and the operation is carried out in sequence to complete nitrogen filling again.

[0026] In the present utility model, by driving the multiple groups of carrier seats 4 to rotate synchronously through the driving motor 5, the sequential progression of the potato chip tubes can be realized, and at the same time, nitrogen filling and sealing, feeding and discharging can be completed, improving the nitrogen filling efficiency. At the same time, through the coordinated use of the infrared receiver 13 and the infrared emitter 14, the operation of the driving motor 5, the push rod 6 and the electromagnetic ring 11 is automatically controlled. During the nitrogen filling and sealing process, the potato chip tube is automatically limited, and the limitation is automatically released during discharging to facilitate discharging, and automatic operation can be realized to reduce the operation steps of personnel.

[0027] Please refer to Figure 1 and 4 : A status indicating lamp 17 is fixedly installed on the top of the processing rack 1, and the status indicating lamp 17 is signal-connected to the processor 15.

[0028] In the present utility model, the processor 15 will control the status indicating lamp 17 to light up corresponding colors in real time, so as to play a prompting role for the user, enabling the user to timely understand the state of the device.

[0029] Please refer to Figure 2 and 3, wherein: a soft pad 18 is fixedly connected to the clamping plate 9, and the soft pad 18 is made of rubber material.

[0030] In the present utility model, when the clamping plate 9 clamps the potato chip tube, the rubber soft pad 18 can improve the clamping effect on the potato chip tube, thereby preventing the outer side of the potato chip tube from being rubbed.

[0031] Please refer to Figures 1 to 3 , wherein: a counterweight ring 20 is fixedly connected to the bearing seat 4, and the counterweight ring 20 is made of metal material.

[0032] In the present utility model, the metal counterweight ring 20 can increase the mass of the bearing seat 4, so that the bearing seat 4 remains stable during vertical movement, avoiding the influence of light mass on sliding.

[0033] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improvement concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
