Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, specifically a rapid film sealing device. Background Technology

[0002] Food packaging is an integral part of food products and one of the major processes in the food industry. It protects food from biological, chemical, and physical damage during its journey from the factory to the consumer. It also helps maintain the stable quality of the food itself, facilitates consumption, and serves as the primary visual representation of the food, attracting consumers and possessing value beyond material cost.

[0003] For example, a device for quickly sealing food packaging films, as described in patent document CN214649453U, includes a base for the quick sealing device. A film placement platform is fixedly installed in the middle of the top outer wall of the base. Two sets of electric lifting column fixing slots are opened on the left and right sides of the top outer wall of the base. A sealing mechanism is provided on the top of the film placement platform. A controller is fixedly installed on the right side of the front outer wall of the base. This device for quickly sealing food packaging films, through its sealing wide-mouth mechanism and adjustable rotating shaft mechanism, utilizes six heating elements of different widths fixedly installed on the outer wall of the sealing wide-mouth mechanism column. When the sealing width needs to be changed, the heating elements are adjusted by pressing the adjustable knob to the right, adapting to different sealing width requirements, improving work efficiency, and bringing better application prospects.

[0004] However, the above-mentioned mechanism has the following problems: First, the lifting mechanism is driven by two sets of electric lifting columns, which may result in different frequencies, causing the lifting mechanism to jam; second, the electric lifting columns cannot be raised and lowered quickly and frequently, which can reduce their service life. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid film sealing device, comprising a movable upper knife holder 10 and a fixed hot pressing plate 12, wherein a hot pressing plate 11 is provided below the movable upper knife holder 10, and the fixed hot pressing plate 12 is fixed on a support base 7. The movable upper knife holder 10 cooperates with guide rods 8 on both sides of the support base 7, and the lower part of the movable upper knife holder 10 is connected to a transmission shaft 15 below the support base 7 through two symmetrical cam linkage mechanisms. The transmission shaft 15 is driven by a servo motor and reducer assembly 1.

[0006] Furthermore, the cam linkage mechanism includes two hinge blocks 4, a cam 5, and a connecting rod 6. The two hinge blocks 4 are respectively hinged to the cam 5 and the lower part of the movable upper tool holder 10. The two ends of the connecting rod 6 are connected to the hinge blocks 4. The cam 5 is fixedly connected to the transmission shaft 15 by bolts and keys.

[0007] Furthermore, the drive shaft 15 passes through the right-angle transmission box 2. A servo motor and reducer assembly 1 is fixed below the right-angle transmission box 2. The right-angle transmission box 2 is located between two support plates 16 and is fixed by bolts. A drive shaft support plate 14 supporting the drive shaft 15 is also provided below the support base 7. A bearing seat 3 that cooperates with the drive shaft 15 is provided on the drive shaft support plate 14.

[0008] Furthermore, the support base 7 is provided with a clearance groove 13 for the clearance link 6.

[0009] This utility model has the following advantages: First, it transmits power to the symmetrical cam mechanisms on both sides through a servo motor and a transmission shaft, and the cam mechanisms drive the upper knife holder to move up and down, thereby achieving rapid edge sealing and avoiding jamming due to inconsistency on both sides; Second, the rapid lifting and lowering driven by the motor improves the edge sealing speed and extends the service life.

Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1 The present invention provides a technical solution: including a movable upper knife holder 10 and a fixed hot pressing plate 12. The movable upper knife holder 10 is provided with a hot pressing plate 11 below it, and the fixed hot pressing plate 12 is fixed on the support base 7.

[0014] The support base 7 has symmetrically arranged guide rods 8 on both sides. The movable upper tool holder 10 cooperates with the guide rods 8 and can move up and down. The lower part of the movable upper tool holder 10 is connected by two symmetrical cam-linkage mechanisms. The cam-linkage mechanism includes two hinge blocks 4, a cam 5, and a connecting rod 6. The two hinge blocks 4 are respectively hinged to the cam 5 and the lower part of the movable upper tool holder 10. The two ends of the connecting rod 6 are connected to the hinge blocks 4. The cam 5 is fixedly connected to the transmission shaft 15 by bolts and keys. The support base 7 is provided with a clearance groove 13 to avoid the connecting rod 6.

[0015] The drive shaft 15 passes through the right-angle transmission box 2. The servo motor and reducer assembly 1 is fixed below the right-angle transmission box 2.
