Description

Technical Field

[0001] This invention relates to the field of heat sealing machine technology, specifically a heat sealing machine with a sterilization protective cover. Background Technology

[0002] Heat sealing machines are commonly used sealing equipment in the fields of medical and health care and aseptic packaging. They mainly use electric heating to heat-press and seal packaging materials such as plastics and composite films. Under the premise of standardized temperature control and matching with special packaging materials, the heat sealing process is only a hot-melt bonding of materials and will not produce harmful gases. The processing environment is safe and controllable, which can meet the packaging requirements of aseptic products. They are widely used in the production and processing of medical consumables and aseptic packaging products.

[0003] Currently, most traditional heat sealing machines adopt an open structure design, lacking sterilization and protection mechanisms. During the material feeding and heat sealing process, external contaminants such as dust, mold, and bacteria can easily enter the processing area directly, causing contamination of the packaging materials and heat-sealed parts. This fails to meet the clean production requirements of medical and health care and aseptic packaging. At the same time, open processing lacks effective isolation and disinfection methods, resulting in poor hygiene and the risk of material contamination by microorganisms, making it difficult to adapt to aseptic processing scenarios.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a heat sealing machine with a sterilization protective cover, in order to achieve a more practical purpose. Summary of the Invention

[0005] The purpose of this invention is to provide a heat sealing machine with a sterilization protective cover to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by the present invention is as follows: A heat sealing machine with a sterilization protective cover includes a heat sealing machine and a protective component. The heat sealing machine includes a base, and a bottom square seat is installed on the top surface of the base. A U-shaped sealing gasket is provided on the outer side of the bottom square seat, and the bottom surface of the sealing gasket is fixedly connected to the top surface of the base. The protective component includes a protective cover, and the bottom surface of the protective cover is sealed and fitted to the top surface of the sealing gasket. Both ends of the protective cover have material discharge ports, and the side walls of the protective cover above the material discharge ports have mounting grooves. An air curtain machine with a sterilization function is installed in the mounting grooves. The air curtain machine integrates ultraviolet sterilization components, and the air outlet of the air curtain machine faces the material discharge ports to form a downward sterile air curtain barrier. The protective cover is made of transparent acrylic material.

[0007] The beneficial effects of adopting the above-mentioned further solution are as follows: by setting discharge ports at both ends of the protective cover, it is convenient for workers or them to operate the material in and out using corresponding robotic arms; when the material to be heat-sealed is sent into the protective cover through the discharge ports, the material first passes through an air curtain machine with a disinfection function. The ultraviolet sterilization component inside the air curtain machine can sterilize and purify the flowing air, and together with the high-speed airflow, it can blow away the floating dust, hair and microorganisms attached to the surface of the material, achieving aseptic treatment before the material enters; at the same time, the aseptic air curtain can block the convection of unclean air from the outside, reducing the entry of external pollutants into the protective cover at the moment of material discharge; the protective cover, together with the U-shaped sealing gasket, forms a relatively sealed cavity, which remains closed during heat sealing operations, effectively preventing dust, mold and bacteria from entering the heat sealing area, and the transparent acrylic material allows workers to observe the internal processing status in real time.

[0008] Furthermore, a pair of slots are provided on the sealing gasket, and a plug plate corresponding to each of the slots is fixedly installed on the bottom surface of the protective cover; the plug plate is inserted into the slot, and the outer wall of the plug plate slides in fit with the inner wall of the slot.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the sliding insertion and slot of the insert plate plays a guiding and limiting role in the installation of the protective cover, avoiding left and right displacement during the assembly of the protective cover, so that the bottom surface of the protective cover can be evenly pressed on the sealing gasket, improving the assembly accuracy, ensuring the overall sealing effect of the protective cover, preventing gaps from causing bacteria and dust to seep in, and further improving the sealing stability of the cavity.

[0010] Furthermore, each of the four corners of the outer wall of the protective cover is provided with a connector, the connector including a bottom connector, a top connector directly above the bottom connector, the bottom connector being fixedly installed at the top corner of the heat sealing machine base, and the top connector being fixedly installed at the bottom corner of the outer wall of the protective cover; the top connector has a through hole inside, a stud is provided in the through hole, the bottom surface of the stud is fixedly connected to the top surface of the bottom connector, and a locking ring is externally threaded to the end of the stud away from the bottom connector, the bottom surface of the locking ring being tightly fitted to the top surface of the top connector.

[0011] The beneficial effects of adopting the above-mentioned further solution are that the protective cover is locked and fixed by the connectors set at the four corners, and the protective cover can be pressed down by rotating the locking ring, so that the protective cover is tightly pressed against the sealing gasket, thereby improving the overall compression and sealing performance; at the same time, it is simple and convenient to disassemble and assemble, making it convenient for staff to disassemble the protective cover later, and clean and sterilize the inside of the protective cover, the sealing gasket and the processing area, thus meeting the requirements for aseptic processing.

[0012] Furthermore, the nominal diameter of the stud is larger than the diameter of the through hole.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the stud diameter is larger than the through hole diameter, so that the stud and the through hole form an interference fit. After assembly, the top connecting seat is not easy to shake or shift, which improves the stability of the protective cover after installation, avoids the protective cover from loosening and creating gaps due to equipment vibration, prevents external pollutants from entering the interior through the gaps, and ensures the airtight protection effect.

[0014] Furthermore, a pressing plate is provided directly above the bottom square base, and a top square base is provided directly above the pressing plate. Sliding holes are provided inside the four corners of the pressing plate, and a smooth rod is provided in the sliding hole. The two end faces of the smooth rod are fixedly connected to the top surface of the bottom square base and the bottom surface of the top square base, respectively. An electric heating plate is installed on the bottom surface of the pressing plate.

[0015] The beneficial effects of adopting the above-mentioned further solution are that the smooth rod plays a vertical guiding and limiting role on the pressing plate, making the up and down movement of the pressing plate more stable and avoiding uneven heat sealing caused by deviation; the electric heating plate can be used to heat the material at a constant temperature, which is simple and stable in structure, has high heat sealing accuracy, and can be used with a sealed protective cover to complete the heat sealing operation in a clean environment, reducing the risk of mold contamination.

[0016] Furthermore, an electric push rod is installed on the top surface of the top seat, and a through hole is opened inside the top surface of the top seat. The movable end of the electric push rod is fixedly connected to the top surface of the pressing plate through the through hole.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the electric push rod drives the pressing plate to automatically press down to complete the heat sealing, which has a high degree of automation, stable and controllable pressing stroke, uniform heat sealing pressure, and improves the heat sealing quality of materials. It eliminates the need for manual pressing, reduces the risk of contamination caused by manual operation, and is suitable for aseptic processing scenarios.

[0018] Furthermore, the height and width of the discharge port are at least adapted to the passage size of the material to be heat-sealed. Even further, the height and width of the discharge port are adapted to the passage size of a human hand or corresponding robotic arm and the material to be heat-sealed together.

[0019] The beneficial effects of adopting the above-mentioned further solution are that the discharge port size is reasonable, which not only makes it convenient for workers to reach in and pick up materials, making the operation convenient and smooth, but also minimizes the opening area, reduces the amount of air exchange during material discharge and retrieval, and reduces the probability of external dust and microorganisms entering the protective cover. Together with the air curtain, it can improve the protective sterilization effect.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: This heat sealing machine with a sterilization protective cover is equipped with material discharge ports on both sides and an air curtain mechanism with disinfection function. The air curtain machine uses a built-in sterilization component to sterilize the airflow. When the material is put in, it is first swept and purified by the sterile air curtain to remove surface impurities and microorganisms. During the material discharge process, the sterile air curtain blocks unclean external air. Under normal conditions, the protective cover is sealed, and the heat sealing process is carried out in a clean and sealed cavity, which effectively prevents dust, mold, and bacterial contamination. At the same time, it is equipped with a guide plate and a four-corner locking structure, which ensures good assembly and sealing. It solves the problems of traditional heat sealing machines that lack sterilization protection, are open for processing, are easily contaminated with dust and mold, and have poor hygiene, thus meeting the heat sealing processing needs of medical and health care and sterile packaging.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-5This invention provides a technical solution: a heat sealing machine with a sterilization protective cover, comprising a heat sealing machine 1 and a protective component 3. The heat sealing machine 1 includes a base 11, and a bottom square seat 12 is mounted on the top surface of the base 11. A U-shaped sealing gasket 2 is provided on the outer side of the bottom square seat 12, and the bottom surface of the sealing gasket 2 is fixedly connected to the top surface of the base 11. The protective component 3 includes a protective cover 31, the bottom surface of which is sealed and fitted to the top surface of the sealing gasket 2. Both ends of the protective cover 31 have discharge ports 32, and the side walls of the protective cover 31 above the discharge ports 32 have mounting grooves 33. An air curtain machine 34 with a sterilization function is installed in the mounting grooves 33, and the air curtain machine 34 integrates ultraviolet sterilization components. The air outlet of the air curtain machine 34 faces the discharge port 32 to form a downward air curtain barrier; the protective cover 31 is made of transparent acrylic material; when the air curtain machine 34 is powered on, its internal ultraviolet sterilization component sterilizes the air flowing through the air curtain machine 34, and the purified airflow is sprayed vertically downward from the air outlet, forming a sterile air curtain barrier at the discharge port 32. The staff can observe the internal processing through the transparent protective cover 31; the air curtain machine 34 with disinfection function is a UV sterilization and purification air curtain machine, model FM-1209 ultraviolet sterilization air curtain machine, which comes with a pre-filter and ultraviolet sterilization lamp, and is suitable for use with a sterile operating table, and can form a sterile isolation air curtain at the discharge port 32.

[0025] The sealing gasket 2 has a pair of slots 4, and the bottom surface of the protective cover 31 is fixedly installed with insert plates 5 corresponding to the pair of slots 4. The insert plates 5 are inserted into the slots 4, and the outer wall of the insert plates 5 slides in cooperation with the inner wall of the slots 4. When installing the protective cover 31, the operator aligns the protective cover 31 with the top of the base 11, so that the insert plates 5 at the bottom of the protective cover 31 are vertically aligned with the slots 4 on the sealing gasket 2, and slides them downwards to insert them. The precise alignment is achieved by the cooperation between the insert plates 5 and the slots 4, preventing the protective cover 31 from being installed off-center.

[0026] The protective cover 31 has connectors 6 at each of its four corners. Each connector 6 includes a bottom connector 61 and a top connector 62 directly above the bottom connector 61. The bottom connector 61 is fixedly installed at the top corner of the base 11 of the heat sealing machine 1, and the top connector 62 is fixedly installed at the bottom corner of the outer wall of the protective cover 31. The top connector 62 has a through hole 63 inside, and a stud 64 is installed inside the through hole 63. The bottom surface of the stud 64 is fixedly connected to the top surface of the bottom connector 61. A locking ring 65 is externally threaded onto the end furthest from the bottom connecting seat 61. The bottom surface of the locking ring 65 fits tightly against the top surface of the top connecting seat 62. After the protective cover 31 is aligned, the stud 64 passes through the through hole 63. The operator rotates the locking rings 65 at the four corners in sequence. The locking rings 65 move down along the stud 64 and press against the top connecting seat 62, so that the entire protective cover 31 presses down to press against the sealing gasket 2, achieving a tight seal. The protective cover 31 can be removed by unscrewing the locking rings 65 in the opposite direction for easy cleaning and maintenance.

[0027] The nominal diameter of the stud 64 is larger than the diameter of the through hole 63. During assembly, the stud 64 and the through hole 63 form an interference fit, and the stud 64 is tightly engaged inside the through hole 63, making the top connecting seat 62 less prone to lateral wobbling, reducing vibration and displacement caused by equipment operation, and ensuring the long-term stability of the protective cover 31.

[0028] The base 12 has a pressing plate 13 directly above it, and a top base 14 is located directly above the pressing plate 13. Sliding holes are formed at the four corners of the pressing plate 13, and smooth rods 15 are installed within these holes. The two ends of the smooth rods 15 are fixedly connected to the top surface of the base 12 and the bottom surface of the top base 14, respectively. An electric heating plate is installed on the bottom surface of the pressing plate 13. During operation, the pressing plate 13 slides vertically along the smooth rods 15, which limit and guide the pressing plate 13, ensuring its vertical up-and-down movement. The electric heating plate is energized to provide a stable heat source for heat sealing the material. The electric heating plate is a cast aluminum constant-temperature heat sealing heating plate, model JY-4030, which is temperature-controlled, heats up evenly, and is suitable for heat sealing of packaging materials.

[0029] The top surface of the top seat 14 is equipped with an electric push rod 16. A through hole is opened inside the top surface of the top seat 14. The movable end of the electric push rod 16 is fixedly connected to the top surface of the pressing plate 13 through the through hole. During the heat sealing process, the electric push rod 16 extends and retracts to drive the pressing plate 13 to move downward, so that the electric heating plate presses the material and completes the automatic heat sealing operation. After the processing is completed, the electric push rod 16 retracts and the pressing plate 13 moves upward to reset.

[0030] The height and width of the discharge port 32 are adapted to the passage size of the human hand or corresponding robotic arm and the material to be heat-sealed. The worker's hand or corresponding robotic arm can directly pass through the discharge port 32 to smoothly feed the material to be heat-sealed into the surface of the bottom square seat 12 inside the protective cover 31. After processing, the material is taken out from the discharge port 32 on the other side. The operation is simple and smooth, and the smaller opening area can reduce the inflow of outside air.

[0031] The protective cover 31 may also be equipped with an additional ultraviolet sterilization component to perform appropriate sterilization treatment on the inside of the protective cover 31.

[0032] Among them, an air curtain machine 34 is respectively installed on the opposite side walls of the protective cover 31. Each of the two air curtain machines 34 has a corresponding discharge port 32 below it. One discharge port 32 is used for the entry of the material to be heat-sealed, and the other discharge port 32 is used for the entry of the material to be heat-sealed, so as to realize the simultaneous blowing of air in opposite directions at the discharge ports 32.

[0033] The protective cover 31 may have two air curtain machines 34 installed on the upper and lower sides of the discharge port 32. That is, in addition to the aforementioned installation groove 33 opened on the side wall of the protective cover 31 above the discharge port 32, another installation groove 33 may be opened on the side wall of the protective cover 31 below the discharge port 32, or a corresponding installation groove 33 may be provided on the base 11.

[0034] Specifically, the working principle of this heat sealing machine with a sterilization protective cover is as follows: Before use, the operator aligns and installs the protective cover 31 with the slot 4 using the insert plate 5, and locks it in place using the connectors 6 at the four corners, so that the protective cover 31 is pressed against the sealing gasket 2 to form a sealed cavity; the equipment is turned on, and the air curtain machine 34 works continuously, with the internal ultraviolet sterilization component sterilizing the air, forming a downward sterile air curtain at the discharge port 32; the operator inserts the material to be heat sealed from one side discharge port 32, and the material completes surface cleaning and sterilization as it passes through the air curtain, and is then placed on the bottom square base 1. 2. Upper end; After placement, start the electric push rod 16. The electric push rod 16 pushes the pressing plate 13 to move vertically downward along the smooth rod 15. The electric heating plate is used to heat seal the material at a constant temperature. After heat sealing, the electric push rod 16 drives the pressing plate 13 to move upward and reset. The staff takes out the processed material from the discharge port 32 on the other side. After long-term use of the equipment, the locking ring 65 can be loosened to quickly remove the protective cover 31, which is convenient for cleaning and disinfecting the inside of the cavity, the sealing gasket 2 and the air curtain machine 34. The whole process is simple to operate and hygienic, and can continuously maintain a sterile processing environment.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. Furthermore, since this application is mainly used to protect mechanical devices, the control methods and circuit connections will not be explained in detail in this application.
