Description

Technical Field

[0001] The invention relates to the technical field of film sealing and cutting equipment, in particular to a sealing and cutting mechanism of a full-automatic film sealing and cutting packaging machine. Background Art

[0002] In the field of product packaging, the sealing and cutting mechanism of the film sealing and cutting packaging machine plays a key role. Traditional sealing and cutting mechanisms often have many limitations, which affect packaging efficiency and quality.

[0003] First, the continuity of sealing and cutting is poor. Most traditional mechanisms do not work well together when sealing and cutting. For example, the transmission coordination between the winding roller and the sealing and cutting components is not optimized, which makes it difficult to accurately connect the film conveying and sealing and cutting actions. When the sealing and cutting knife is cutting, the film conveying is prone to stagnation or uneven speed, resulting in interruption of sealing and cutting. Frequent adjustment of equipment parameters or manual intervention is required, which seriously slows down the overall progress of the packaging process, increases production costs and time consumption, and cannot meet the needs of modern high-speed production.

[0004] Second, the film separation and lamination accuracy is low. Some old-fashioned equipment handles the film group roughly and does not have an effective separation structure. During the film conveying and sealing and cutting conversion, the upper and lower films are prone to adhesion or misalignment, resulting in poor packaging sealing and many appearance defects.

[0005] Third, the defects in the heat sealing and cutting process are prominent. Traditional sealing and cutting mechanisms mostly rely on a single heating and cutting tool. The tool is prone to wear and deformation due to long-term high temperature, and needs to be frequently replaced and maintained, which increases equipment downtime and operation and maintenance costs. Moreover, the thermal inertia of the tool is large after heating, making it difficult to accurately control the sealing and cutting temperature and time, which can easily lead to excessive or insufficient heat sealing of the film, resulting in quality problems such as film rupture and loose sealing, reducing packaging reliability, causing increased risks of product leakage and deterioration, and causing economic losses and reputation damage to the company.

[0020] The present invention provides a sealing and cutting mechanism for a fully automatic film sealing and cutting packaging machine. It has the following beneficial effects:

[0021] 1. The sealing and cutting mechanism of this fully automatic film sealing and cutting packaging machine, the motor drives the second winding roller to rotate, while the transmission belt rotates and links the transfer rod, the inner end of the transfer rod is connected to the crank, the two ends of the crank rotate on the inner surface of the bottom of the side plate, and the output end is connected to the drive plate, the drive plate is hinged with the extrusion plate, so that the extrusion plate moves up and down reciprocatingly, the friction belt on the inner surface of the transmission belt cooperates with the friction ring of the transfer rod, because the rotating shaft of the second winding roller is smooth, its intermittent rotation is realized, and the first winding roller is coordinated to pull the film group forward intermittently, and it stops when the forward movement is completed. The design of the crank makes the sealing and cutting assembly always in working state, that is, the continuous up and down movement of the sealing and cutting mechanism and the intermittent advancement of the film group are coordinated to ensure the continuity of sealing and cutting, thereby greatly improving the production efficiency.

[0022] 2. In the sealing and cutting mechanism of this fully automatic film sealing and cutting packaging machine, when the extrusion plate moves down and contacts the film group, the combing roller contacts the two sides of the upper film first, and due to the inclined design on the inner side of the bearing strip, the combing roller will roll toward the product side while squeezing the upper film. Because the puncture needle has made the two sides of the upper film relatively weak, the continuous downward movement and squeezing of the combing roller causes the two sides of the upper film to be gradually torn and separated and follow the combing roller to approach the product, fitting the outer surface of the product, reducing the sealing and cutting area to reduce the waste of film, and at the same time, it can also reduce the retained air in the film to avoid expansion damage during subsequent processing.

[0023] 3. The sealing and cutting mechanism of the full-automatic film sealing and cutting packaging machine has a top ring connected to an extrusion ring on the lower surface of the middle part of the extrusion plate, and a heating ring and an electric contact are arranged in the gap between the inner and outer rings. The cutting ring is inserted in the gap between the extrusion rings and the top is connected to the bottom surface of the top ring, and is located on the outside of the heating ring. The extrusion plate is pressed downward, and the pressure is transmitted to the extrusion ring through the top ring to make the heating ring move up to turn on the electricity to heat and press the film, and then the cutting ring is cut. This design prevents the film from being damaged by excessive heating. At the same time, the usual sealing and cutting is to heat the cutting knife and complete the hot pressing through the cutting knife, but the cutting knife must be in a heated state all the time and does not have the conditions for automatic opening and closing, which is prone to safety hazards. At the same time, the film edge after the hot pressing of the cutting knife is weakly connected, which is easy to cause sealing and cutting defects. The design of the heating ring perfectly solves this problem and greatly improves the sealing and cutting quality. The rubber rings inlaid on both sides of the first separation ring ensure the stable rotation of the first separation ring and the second separation ring, and avoid relative sliding between the upper film and the puncture needle, which may cause scratches on the upper film.

The bottom surfaces of both sides of the extrusion plate 59 are symmetrically fixedly connected with support bars 511, and the inner side of the support bar 511 is arranged in an inclined shape. A slide groove 512 is provided on the inner side of the support bar 511, and a limiting rod 513 is fixedly connected in the slide groove 512. A pressure plate 514 is elastically slidably sleeved on the limiting rod 513, and a combing roller 515 is rotatably connected to the bottom of the pressure plate 514.

[0046] A top ring 516 is fixedly connected to the lower surface of the middle part of the extrusion plate 59, and an extrusion ring 517 is provided below the top ring 516. Both sides of the extrusion ring 517 are elastically connected to the lower surface of the extrusion plate 59 through telescopic rods. The extrusion ring 517 is divided into inner and outer rings, and the inner and outer rings are fixedly connected. At the same time, a gap is provided between the inner and outer rings.

A cutting ring 520 is slidably inserted in the internal gap of the extrusion ring 517, and the top of the cutting ring 520 is fixedly connected to the bottom surface of the top ring 516. The cutting ring 520 is arranged on the outside of the heating ring 518.

[0047] During operation, if the product needs to be sealed and cut, the motor 44 can be started. After the motor 44 is started, the transmission structure connected to its output shaft drives the second winding roller 42 to rotate. Since the second winding roller 42 is linked with the first winding roller 41 through the front rod 46 and the film group 47, the upper film 48 and the lower film 49 are stretched and drive the film group 47 forward. The two ends of the front rod 46 are rotatably connected to the inner surfaces of both sides of the first mounting frame 2, and the outer surface thereof is in contact with the film group 47. The tail of the upper film 48 is wrapped around the first winding roller 41, and the tail of the lower film 49 is wrapped around the second winding roller 42. In this process, the first separation rod 410 rotatably connected to the inner surface of the top of the first mounting frame 2 and the second separation rod 411 below play a role. Both ends of the two are rotatably connected to the inner surface of the top of the first mounting frame 2. The first separation rod 410 The two ends are sleeved with the first separation ring 412, and the second separation ring 413 is sleeved on the two ends of the second separation rod 411. The two are connected in rotation to help separate the film group 47. At the same time, the motor 44 drives the second winding roller 42 to rotate. At the same time, the transmission belt 45 rotates and links the transfer rod 54. The inner end of the transfer rod 54 is connected to the crank 57. The two ends of the crank 57 rotate on the inner surface of the bottom of the side plate 53. Its output end is connected to the driving plate 58. The driving plate 58 is hinged with the extrusion plate 59 to cause the extrusion plate 59 to move up and down reciprocatingly. The friction belt 56 on the inner surface of the transmission belt 45 cooperates with the friction ring 55 of the transfer rod 54. Because the rotating shaft of the second winding roller 42 is smooth, its intermittent rotation is realized, and the first winding roller 41 is coordinated to pull the film group 47 intermittently forward, and the forward movement is stopped at the end. The design of the crank 57 makes the sealing and cutting assembly It is always in working state, that is, the sealing and cutting assembly 5 is constantly moved up and down and the film group 47 is intermittently advanced to ensure the continuity of sealing and cutting, thereby greatly improving the production efficiency. At the same time, when the extrusion plate 59 moves down and contacts the film group 47, the combing roller 515 first contacts the two sides of the upper film 48, and due to the inclined design on the inner side of the supporting strip 511, the combing roller 515 will roll toward the product side when squeezing the upper film 48. Because the puncture needle 415 has made the two sides of the upper film 48 relatively weak, the continuous downward movement and squeezing of the combing roller 515 causes the two sides of the upper film 48 to be gradually torn and separated, and follow the combing roller 515 to approach the product, fit the outer surface of the product, reduce the sealing and cutting area to reduce the waste of the film, and at the same time reduce the retained air in the film to avoid expansion damage during subsequent processing. At the same time, the two ends of the buckle cover 510 slidably connected to the outside of the extrusion plate 59 are connected to the bottom of the second mounting frame 3 through a connecting rod to provide support and guidance for the extrusion plate 59. The top ring 516 on the lower surface of the middle part of the extrusion plate 59 is connected to the extrusion ring 517. The gap between the inner and outer rings has a heating ring 518 and an electric contact 519. The cutting ring 520 is inserted into the gap between the extrusion ring 517 and the top is connected to the bottom surface of the top ring 516. At the same time, it is located on the outside of the heating ring 518. The extrusion plate 59 is pressed down, and the pressure is transmitted to the extrusion ring 517 through the top ring 516, so that the heating ring 518 moves up to turn on the electricity to heat and press the film, and then the cutting ring 520 cuts. This design prevents excessive heating from damaging the film. At the same time, the usual sealing and cutting is to heat the cutting knife and complete the hot pressing through the cutting knife, but the cutting knife must be in a heated state all the time.It does not have the conditions for automatic opening and closing, which is prone to potential safety hazards. At the same time, the thin film edge connection after hot pressing by the cutting knife is weak, which is easy to cause sealing and cutting defects. The design of the heating ring 518 perfectly solves this problem and greatly improves the sealing and cutting quality. The rubber rings 414 embedded on both sides of the first separation ring 412 ensure the stable rotation of the first separation ring 412 and the second separation ring 413, and avoid the upper film 48 and the puncture needle 415 from sliding relative to each other, which may cause the upper film 48 to be scratched.
