Description

Technical Field

[0001] This utility model relates to the field of sealing machine technology, and more specifically, to a sealing machine for special dietary supplements. Background Technology

[0002] A film sealing machine (also known as a film sealing machine or plastic sealing machine) is a type of packaging equipment. Its core function is to seal plastic films (such as PE, PP, PET, etc.) with packaging bags (aluminum foil bags, composite bags, etc.) through heat sealing, pressure, or shrink technology to achieve purposes such as moisture prevention, dust prevention, and extending shelf life. When placing special dietary supplements in cans, a film sealing machine is needed to seal the cans.

[0003] However, in actual use, traditional special dietary supplement sealing machines are not equipped with auxiliary cleaning and heating structures, which makes it impossible to clean the can opening before sealing. As a result, impurities at the can opening can affect the sealing performance. Furthermore, the can opening cannot be preheated before sealing, which makes it impossible to reduce the temperature difference during hot-press sealing. Sudden temperature changes can easily cause the sealing film to crack or adhere unevenly, which can lead to leakage of the special dietary supplement inside the can. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a special dietary supplement sealing machine. This addresses the problem that the existing technology lacks auxiliary cleaning and heating structures, making it impossible to clean the can opening before sealing. This results in impurities at the can opening affecting the sealing performance. Furthermore, the inability to preheat the can opening before sealing prevents the reduction of temperature differences during hot-press sealing, leading to cracking or uneven adhesion of the sealing film due to sudden temperature changes, ultimately causing leakage of the special dietary supplements inside the can.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a special dietary supplement sealing machine, including a bottom support and a back plate fixed to the top back of the bottom support. A placement seat for placing the can is slidably provided on the front of the top of the bottom support. A fixing frame is fixed on the front of the top of the bottom support. Fixed shafts are rotatably installed on both sides of the top of the front of the back plate. A roller for winding the sealing film is provided at one end of each fixed shaft.

[0015] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0016] Example: Please refer to Figures 1 to 5This utility model provides a technical solution: a special dietary supplement sealing machine, including a bottom support 1 and a back plate 2 fixed to the top back of the bottom support 1. A placement seat 12 for placing the can is slidably arranged on the front of the top of the bottom support 1. A controller is arranged on the right side of the front of the bottom support 1. A fixing frame 15 is fixed to the front of the top of the bottom support 1. Fixed shafts 3 are rotatably mounted on both sides of the top of the front of the back plate 2. A roller 6 for winding the sealing film is arranged at one end of each fixed shaft 3. Guide rollers 8 for guiding the sealing film are rotatably mounted on both sides of the bottom of the front of the back plate 2. A motor 4 is fixed to the back of the back plate 2. The output shaft end of the motor 4 is fixed to one of the fixed shafts 3. The motor 4 can drive one of the fixed shafts 3 and the roller 6 on it to rotate, so as to wind up the waste sealing film after heat pressing. Simultaneously, it can drive another set of fixed shafts 3 and the roller 6 to rotate, causing the unheat-pressed sealing film on the roller 6 to be released. Each set of fixed shafts 3 is fixed with a positioning plate 5 that is attached to the back of the drum 6. The section of the fixed shaft 3 inside the drum 6 is uniformly and integrally formed with multiple sets of protrusions. The drum 6 has a groove that works with the protrusions. Each set of fixed shafts 3 has a locking bolt 7 that is engaged with the internal thread. The protruding end of the locking bolt 7 is attached to the front of the drum 6. The design of the positioning plate 5, the protrusions and the grooves allows the drum 6 to be pre-positioned and locked. The engagement of the locking bolt 7 and the internal thread allows the drum 6 to be quickly locked and fixed after being locked, and it is convenient to disassemble and replace it later. The other end of the other set of fixed shafts 3 is fitted with a rubber sleeve 28. The outer ring of the rubber sleeve 28 is fixed with a fixing sleeve 27 that is fixed to the back of the back plate 2. The fixing sleeve 27 can limit the position of the rubber sleeve 28 so as to increase the rotational friction of the other set of fixed shafts 3, so that the other set of fixed shafts 3 can rotate stably and avoid the sealing film on it from loosening due to inertia. A small cylinder 9 is fixed to the front of the back plate 2 via a side frame. The piston rod of the small cylinder 9 is fixed to an annular heating strip 10, which works with the sealing film and the can, via a chassis. The design of the annular heating strip 10, and its vertical position change with the small cylinder 9, allows for heat pressing of the sealing film, enabling it to quickly adhere to the can opening. Second electric push rods 14 are embedded on both sides of the placement base 12. The piston rod of the second electric push rod 14 is fixed to a circular pressure block whose inner side is attached to the can. The bottom support 1 has a longitudinal... The device has a strip-shaped sliding groove. The bottom of the bottom support 1 is embedded with an electric slide rail 11 located on the left side of the strip-shaped sliding groove. A connecting frame 13 is fixed on the electric slide rail 11, with one end passing through the strip-shaped sliding groove and fixed to the bottom of the placement seat 12. The second electric push rod 14 cooperates with the circular pressure block to quickly fix the tank. The design of the electric slide rail 11, in conjunction with the connecting frame 13, allows the position of the tank to be changed, facilitating the rapid hot-press sealing of the tank and improving the overall automation level of the device. The fixed frame 15 is equipped with an auxiliary component that works with the tank. The auxiliary component includes a movable frame 29 that is slidably disposed within the fixed frame 15. Both ends of the movable frame 29 are snapped onto the fixed frame 15. Both ends of the movable frame 29 have a U-shaped structure, which limits the position and shape of the movable frame 29 so as to limit its sliding movement and improve its stability during movement, preventing tilting or deviation. A contact plate 17 is rotatably mounted on the bottom of the movable frame 29. A wiping cotton 18 for wiping the tank opening is provided at the bottom of the contact plate 17. A snap-fit ​​track 26 is symmetrically fixed on the top of the wiping cotton 18. A snap-fit ​​plate 25 fixed on the top of the contact plate 17 is snapped into the snap-fit ​​track 26. The snap-fit ​​between the snap-fit ​​track 26 and the snap-fit ​​plate 25 allows the wiping cotton 18 to be quickly disassembled and installed for easy replacement. A small heater 19 is fixed to the convex plate on the back of the movable frame 29. The air outlet of the small heater 19 is connected to an air pipe 20 with a telescopic tube structure in the middle section. A cavity 21 is opened in the contact plate 17. Multiple sets of vent holes 22 are evenly opened at the bottom of the contact plate 17, which are interconnected with the cavity 21 and used in conjunction with the wiping cotton 18. The bottom end of the air pipe 20 is embedded in the contact plate 17 and interconnected with the cavity 21. Springs 24 are symmetrically fixed on the left and right sides of the contact plate 17. The top end of the spring 24 is fixed to the convex plate on the back of the movable frame 29. Arc-shaped frame bodies 23 are symmetrically inserted on the convex plate on the back of the movable frame 29. The bottom end of the arc-shaped frame body 23 passes through the spring 24 and is fixed to the contact plate 17. The design of the arc-shaped frame body 23 can limit the movement trajectory of the spring 24 and simultaneously improve the overall swing stability of the contact plate 17. A first electric piston rod is embedded in the fixed frame body 15 and fixed to the movable frame 29. The push rod 16, through the auxiliary components and the spring 24, can provide a certain pushing force to the contact plate 17, so that the wiping cotton 18 can contact the can opening in real time when the can moves. This allows the wiping cotton 18 to quickly wipe the can opening before the can moves to the sealing film, quickly wiping away dust and impurities at the can opening, improving the cleanliness of the can opening and preventing impurities from affecting the sealing performance of the sealing film. The design of the small heater 19, air pipe 20, cavity 21 and vent 22 can heat the wiping cotton 18, so that the can opening can be preheated simultaneously when the wiping cotton 18 wipes the can opening. This not only prevents the can from being affected by impurities at the can opening, but also reduces the temperature difference during hot sealing, preventing the sealing film from cracking or unevenly adhering due to sudden temperature changes, thus improving the sealing performance and preventing the leakage of special dietary supplements inside the can.

[0017] The working process of this utility model is as follows: Initially, under the action of spring 24, contact plate 17 and wiping cotton 18 are in a downward tilted position. The small heater 19 is activated by the controller, allowing hot air to be delivered to the cavity 21 via air pipe 20 and evenly sprayed towards the wiping cotton 18 through multiple sets of vents 22, heating the wiping cotton 18. The wiping cotton 18 has numerous tiny pores within its fibers, allowing hot air to circulate and maintain a certain temperature. The user places the canister in the placement base 12 and activates the second electric... Push rod 14: At this time, the second electric push rod 14 can drive the circular pressure block to move and fit against the can body, fixing the can body. Then, the user opens the electric slide rail 11 through the controller, which can drive the connecting frame 13 to move, thereby driving the placement seat 12 and the can body to move towards the sealing film position. At this time, the can opening will contact the inclined wiping cotton 18, and as the can body moves, the wiping cotton 18 will change its angle synchronously and be in a horizontal state. The wiping cotton 18 will be in constant contact with the can opening. At this time, before the can body moves to the sealing film... The cleaning cotton 18 is used to quickly wipe the can opening, removing dust and impurities. This improves the cleanliness of the can opening and prevents dust and impurities from affecting the sealing film's seal. Furthermore, the wiping cotton 18 has a certain temperature, which simultaneously preheats the can opening while wiping. This prevents impurities at the can opening from affecting the sealing performance and reduces temperature differences during heat sealing, preventing the sealing film from cracking or unevenly adhering due to sudden temperature changes, thus improving the sealing effect. To prevent leakage of special dietary supplements inside the can, the can is moved until it is below the sealing film. At this time, the user activates the small cylinder 9 through the controller, which drives the annular heating strip 10 to move down and heat-press the sealing film onto the can opening. The motor 4 drives the right drum 6 to rotate, simultaneously winding up the waste sealing film after heat pressing. The left drum 6 can simultaneously release the unpressed sealing film. After heat pressing is completed, the first electric push rod 16 controls the contact plate 17 and the wiping cotton 18 to move up to avoid affecting the normal reset of the can.
