Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Sealing devices are equipment used to seal packaging materials or containers. They play a vital role in the packaging production process of various industries, including food, pharmaceuticals, cosmetics, and daily necessities. Their main function is to ensure the airtightness of the packaging, preventing the contents from being affected by external contamination, oxidation, moisture, and other adverse factors, while also helping to extend the product's shelf life.

[0023] There are many types of sealing devices. Based on different packaging materials and sealing methods, they can be divided into heat-sealing devices, adhesive sealing devices, and mechanical sealing devices, among others. Heat-sealing devices are typically used for sealing thermoplastic materials such as plastic films. A heating element heats the film to a molten state, and then pressure is applied to bond two or more layers of the film together. This sealing method offers advantages such as fast sealing speed and good sealing performance, and is widely used in food packaging such as bagged foods and pharmaceutical packaging. Adhesive sealing devices use adhesives to bond the edges of packaging materials together. They are suitable for materials that cannot be directly heat-sealed, such as cardboard boxes. Different adhesives can be selected to meet different sealing requirements, ensuring the strength and reliability of the seal. Mechanical sealing devices achieve sealing through mechanical structures such as folding and pressing the packaging material. For example, in the sealing process of some rigid packaging containers, mechanical devices firmly fix the lid to the container. This sealing method is commonly used for sealing containers such as glass bottles and metal cans.

[0024] The design and selection of sealing devices require comprehensive consideration of factors such as the characteristics of packaging materials, the nature of the product, production efficiency, and cost to ensure the sealing process is efficient, stable, and safe. In modern packaging production lines, sealing devices are often integrated with automated control systems, enabling precise control of the sealing position, detection of sealing strength, and fault alarms, thereby improving the automation level of packaging production and product quality.

[0025] The sealing device bracket is a key component of sealing equipment, serving to support and secure the sealing mechanism, ensuring the stability and accuracy of the sealing operation. The bracket is typically made of high-strength materials to withstand various forces and thermal effects during the sealing process, guaranteeing long-term stable operation of the equipment. In packaging production, the sealing device bracket, through its precise positioning and guiding function, enables the sealing mechanism to accurately seal packaging materials or containers, thereby ensuring the airtightness and integrity of the packaging. The design of the bracket needs to comprehensively consider production efficiency, packaging material characteristics, and ease of operation to meet the packaging needs of different industries and scenarios.

[0026] like Figures 1-6 As shown, the adjustable rotary sealing device bracket includes a sealing bracket 1 and a rotating cylinder 2. A connecting frame is installed below the sealing bracket 1, and the rotating cylinder 2 is installed between the connecting frame and the sealing bracket 1. A connecting plate is installed inside the connecting frame. A copper guide sleeve 6 is fitted inside the connecting plate at the lower end of the rotating cylinder 2. An internal thread 8 is formed at the lower end of the rotating cylinder 2 below the copper guide sleeve 6. Through the cooperation of the rotating cylinder 2 and the copper guide sleeve 6, the vertical adjustment function of the sealing bracket 1 is realized, ensuring a more stable and precise adjustment process. The copper guide sleeve 6 improves the vertical adjustment function. The wear resistance and thermal conductivity of the structure extend the service life of the device. Inside the connecting frame, below the connecting plate, there is a positioning plate. An adjusting screw 11 is installed at the lower end of the positioning plate. The outer end of the adjusting screw 11 has an external thread 10. The adjusting screw 11 is threaded to the rotating drum 2 through the external thread 10. The threaded connection between the adjusting screw 11 and the rotating drum 2 makes the up and down adjustment of the sealing bracket 1 more flexible and the operation simple and convenient. Moreover, the positioning plate provides stable support for the adjusting screw 11, ensuring the stability of the adjustment process.

[0027] Please see Figures 2-4 An adjusting bevel gear 12 is installed inside the connecting frame on one side of the adjusting screw 11. A handle is fixed to the outer end of the adjusting bevel gear 12. The adjusting bevel gear 12 is meshed with the adjusting screw 11. The adjusting bevel gear 12 is connected to the handle, allowing the operator to easily adjust the sealing bracket 1 up and down by rotating the handle, improving the convenience of operation. Secondly, the meshing transmission method of the bevel gear can provide a stable adjusting torque, ensuring adjustment accuracy. An elongated hole 7 is opened on the outer wall of the rotating drum 2. A connecting sleeve is installed inside the elongated hole 7, connecting... A positioning button 9 is installed on one side of the sleeve. The elongated hole 7 and the connecting sleeve allow the positioning button 9 to move flexibly on the outer wall of the rotating drum 2, which facilitates quick positioning of the sealing bracket 1. A positioning pin 13 is installed inside the connecting sleeve. Multiple sets of ball bearings 14 are circumferentially installed on the outer end of the positioning pin 13 on the inner side of the connecting sleeve. A connecting spring 15 is sleeved on the side of the positioning pin 13 away from the multiple sets of ball bearings 14. The ball bearings 14 reduce the friction between the positioning pin 13 and the connecting sleeve, making the movement of the positioning pin 13 smoother and improving the sensitivity of the adjustment.

[0028] Please see Figures 3-6 The sealing bracket 1 is equipped with a sealing cylinder 5 inside. A positioning block is fixed on the inner wall of the sealing bracket 1. The sealing cylinder 5 is installed and fixed with the positioning block. The sealing cylinder 5 can provide stable sealing pressure and ensure the consistency of sealing quality. A shaping block 3 is installed on one side of the rotating drum 2 at the lower end of the sealing bracket 1. A heating block 4 is installed on one side of the shaping block 3. A connecting frame is installed on the upper end of the shaping block 3 and the heating block 4. The shaping block 3 and the heating block 4 are installed with the sealing cylinder 5 through the connecting frame. The cooperation of the shaping block 3 and the heating block 4 can ensure that the packaging bag can be heated and fused and shaped during the sealing process, ensuring the aesthetics and sealing effect of the sealing effect. A positioning bolt is provided at the lower corner of the connecting frame. A connecting block is installed at the lower end of the connecting frame. The positioning bolt passes through the connecting frame and is threadedly fixed to the connecting block.

[0029] When using the device for sealing, the sealing bracket 1 is first fixed on the upper side of the rotating drum 2. A sealing cylinder 5 is set inside the sealing bracket to provide pressing power. A heating block 4 and a shaping block 3 are fixed at the front end of the sealing bracket. The rotating drum 2 is installed in the copper guide sleeve 6 to ensure that it can slide up and down. A positioning elongated hole 7 is set on the side wall of the rotating drum 2 to restrict the rotation of the rotating drum 2. An internal thread 8 is set at the lower end of the rotating drum 2. An adjusting screw 11 is set on the lower side of the rotating drum 2. The upper end of the adjusting screw 11 has an external thread 10, which is threaded with the rotating drum 2. The lower end of the adjusting screw 11 is an adjusting bevel gear 12, which is engaged with the adjusting bevel gear 12. When the adjusting bevel gear 12 is rotated, it will drive the adjusting screw 11 to rotate. The rotation of the upper end of the adjusting screw 11 will drive the rotating drum 2, whose rotational freedom is restricted, to move up and down, thereby achieving the purpose of adjusting the sealing bracket 1 up and down.

[0030] Secondly, a positioning elongated hole 7 is provided on the side wall of the rotating drum 2, and a positioning button 9 is installed at the corresponding position. The same positioning elongated hole 7 is set again at the corresponding position of the required rotation angle. The positioning pin 13 inside the positioning button 9 is in the default state of being pressed and popped out by the connecting spring 15. When the positioning button 9 applies pressure, the internal ball 14 will force the positioning pin 13 to move outward, thereby disabling the positioning function. After the pressure of the positioning button 9 is removed, the internal connecting spring 15 will press the positioning pin 13 inward again to realize the positioning function. When the positioning pin 13 is in action, the rotational freedom of the sealing bracket is restricted. When rotation is required, pressure is applied to the positioning button 9, and the positioning pin 13 pops out in the positioning hole, allowing the sealing bracket to rotate freely. After releasing the positioning button 9 and rotating the sealing bracket to the corresponding angle, due to the elastic force applied by the internal connecting spring 15 of the positioning button 9, the positioning pin 13 will be inserted into another positioning hole again. At this time, the sealing bracket is facing outward and in a fixed state, allowing the cleaning and replacement of the heating block 4 to be performed.
