[0019] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0020] Embodiment 1
[0021] In order to make the packaging bag of the pad easier to tear open during use and maintain the sterile environment inside the packaging bag, Figure 1 As an embodiment of the present invention, an antibacterial coated paper easy-to-tear packaging bag for gynecological pads is proposed, including a packaging bag body 1, an overlapping area is provided at the top of the packaging bag body 1, a top heat seal strip 2 is provided at the top of the packaging bag body 1, end heat seal strips 3 are provided at both ends of the packaging bag body 1, and an antibacterial adhesive strip 4 is fixedly connected to the inner wall of the packaging bag body 1 near the end heat seal strip 3. The packaging bag is made of coated paper and is formed through heat sealing. The ratio of the coated paper is 40g of base paper + 18g of PE coating. Two antibacterial adhesive strips 4 are arranged inside the packaging bag to further block the entry of bacteria outside the packaging bag and ensure that the pad is always in a sterile environment. The material of the packaging bag makes it more environmentally friendly and easy to tear.
[0022] Embodiment 2
[0023] In order to improve the utilization of heat during heat sealing of the pad packaging bag and reduce the heat loss of the heating plate to the environment, refer to Figure 2-Figure 5On the basis of the first embodiment, the production equipment of the antibacterial coated paper tearable packaging bag for gynecological pads comprises a conveying platform 5 with supporting legs installed at both ends, the outer sleeve of the conveying platform 5 is provided with a heat cutting machine body 6 for heat-sealing the two ends of the coated paper, the bottom of the heat cutting machine body 6 is fixedly connected with a plurality of supporting legs, one side of the conveying platform 5 is fixedly connected with a side plate 7, one side of the side plate 7 is installed with a guide component 8 and a top heat sealing component 9, and a heat collecting component 10 is installed between the heat cutting machine body 6 and the conveying platform 5. When in use, the coated paper moves on the conveying platform 5, the pad is placed on the coated paper, and the two sides are guided upward by the guide component 8 to bend, and then the overlapping part after the top is bent is heat-sealed by the top heat sealing component 9, and the coated paper continues to be driven forward by the conveying platform 5 until it moves to the heat cutting machine body 6, and the temperature of the electric heating plate of the heat cutting machine body 6 is set to 180°C. When the coated paper passes the electric heating plate, the two ends are heat-sealed and cut by the heat cutting machine body 6 to form a completed packaging bag.
[0024] Since both sides of the hot cutter body 6 are wrapped by the heat collection component 10, the heat on the electric heating plate of the hot cutter body 6 cannot be diffused to a larger range after dissipating into the environment, and can only remain inside the hot cutter body 6. As the air inside the hot cutter body 6 is gradually heated by the electric heating plate and the temperature rises, the temperature difference between the electric heating plate and the surrounding environment decreases, which will cause the speed at which the heat on the electric heating plate dissipates to the surrounding to slow down, and the heat wrapped by the heat collection component 10 can also be guided to a designated position for utilization, which can collect the heat during the production of the packaging bag, and at the same time slow down the heat dissipation speed of the electric heating plate of the hot cutter body 6, reduce the amount of electricity required by the hot cutter body 6 to heat the electric heating plate, improve the utilization of the heat of the electric heating plate and the surface of the packaging bag during the production of the pad packaging bag, reduce heat loss, and at the same time prevent the surrounding environment from continuously heating up, resulting in a situation where the working conditions of the staff become worse.
[0025] In order to prevent the heat around the electric heater from dissipating and recover the heat on the surface of the packaging bag, refer to Figure 4 and Figure 5The heat collection component 10 includes a plurality of hooks 101 rotatably connected to both sides of the heat cutting machine body 6. A plastic film 102 is installed on the outside of the hook 101. A metal rod 103 is fixedly connected to the bottom of the plastic film 102. A heat dissipation groove is provided on the side of the metal rod 103 close to the heat cutting machine body 6. A plurality of separation grooves penetrating the lower half of the plastic film 102 are provided at the bottom of the metal rod 103. When in use, the plastic film 102 naturally falls until the metal rod 103 at the bottom contacts the conveying platform 5. Since the lower half of the plastic film 102 and the metal rod 103 are divided into a plurality of small sections, they can fit the different heights of the conveying platform 5, reducing the gaps on both sides of the heat cutting machine body 6 that can dissipate heat to the outside. When the coated paper is conveyed into or out of the heat cutting machine body 6 by the conveying platform 5, the coated paper is discharged from the bottom of the metal rod 103. The plastic film 102 seals the heat cutter body 6 from both sides, so that the heat on the electric heating plate of the heat cutter body 6 cannot continue to diffuse outward after dissipating into the inside of the heat cutter body 6, and collects the heat of the electric heating plate of the heat cutter body 6. After the coated paper is heat-sealed at both ends into a packaging bag by the electric heating plate of the heat cutter body 6, some heat will remain on the packaging bag due to contact with the electric heating plate. When the packaging bag moves to the outside of the heat cutter body 6, the packaging bag contacts the metal rod 103, and the heat on the packaging bag is transferred to the metal rod 103. The heat dissipation groove on the side of the metal rod 103 close to the heat cutter body 6 increases the speed at which the surface heat dissipates into the inside of the heat cutter body 6, so that the heat on the electric heating plate of the heat cutter body 6 and the residual heat on the packaging bag are collected, thereby reducing heat loss.
[0026] In order to ensure that the plastic film 102 wraps both sides of the heat cutter body 6 and prevents the plastic film 102 from deflecting and leaking due to the positive or negative pressure inside the heat cutter body 6, refer to Figure 3 and Figure 4 , a baffle 11 corresponding to the plastic film 102 is provided on the top of the heat cutter body 6, one end of the baffle 11 is movably extended to between the heat cutter body 6 and the conveying platform 5, and a protrusion 12 is fixedly connected to the top of the baffle 11. When in use, the staff holds the protrusion 12 and pushes the baffle 11 down until a small gap is left between the baffle 11 and the conveying platform 5 to accommodate the packaging bag passing through. Since the electric heating plate of the heat cutter body 6 gradually increases the temperature of the air inside the heat cutter body 6, the air pressure inside the heat cutter body 6 will gradually increase. When the staff extracts the hot air inside the heat cutter body 6 for use, the air pressure inside the heat cutter body 6 will decrease. At this time, the plastic film 102 will move into the heat cutter body 6 under the action of the air pressure difference on both sides. During the movement, the plastic film 102 is blocked by the baffle 11, which can maintain the shape of the plastic film 102, prevent the plastic film 102 from deviating due to the air pressure difference between the inside and outside of the heat cutter body 6 and causing air leakage, thereby ensuring the collection of heat inside the heat cutter body 6.
[0027] Embodiment 3
[0028] In order to utilize the heat collected inside the heat cutting machine body 6, refer to Figure 2-Figure 7 On the basis of the first embodiment, one side of the heat cutting machine body 6 is provided with two curved pipes 13, one end of which extends to between the heat cutting machine body 6 and the conveying platform 5. The top two sides of the conveying platform 5 are fixedly connected with limiting rings 14 for limiting the curved pipes 13. The end of the curved pipe 13 away from the heat cutting machine body 6 is provided with an extension pipe 15, one end of which is movably extended to the inside thereof. The end of the extension pipe 15 away from the curved pipe 13 is connected with a hose 16. The extension pipe 15 movably penetrates the limiting ring 14. A plurality of anti-slip grooves are provided on the top of the extension pipe 15. An exhaust fan 20 is installed at one end of the curved pipe 13 close to the heat cutting machine body 6. When it is necessary to utilize the heat collected inside the heat cutting machine body 6, the exhaust fan 20 is started. The exhaust fan 20 draws the heated air between the two plastic films 102 inside the heat cutting machine body 6 into the curved pipe 13, and then discharges it after passing through the extension pipe 15. The heat collected inside the heat cutting machine body 6 can be guided to a specified position, which is convenient for effectively utilizing the heat collected inside the heat cutting machine body 6.
[0029] Since the two sides of the laminated paper will be bent upward when passing through the guide assembly 8 to facilitate heat sealing of the side surfaces, the laminated paper may be wrinkled when being bent, which will affect the appearance of the packaging bag. In order to reduce the possibility of wrinkles on the laminated paper when being bent, refer to Figure 7 , the staff presses the hand on the anti-slip groove, and then pushes the extension tube 15 toward the position where the laminated paper guided component 8 begins to bend, and then rotates the hose 16 to make the hose 16 face the position where the laminated paper guided component 8 begins to bend. After the exhaust fan 20 extracts the hot air inside the heat cutter body 6, the hot air finally passes through the hose 16 and sprays toward the position where the laminated paper guided component 8 begins to bend. First, the hot air is used to preheat the laminated paper to soften the laminated paper and reduce the possibility of wrinkles when the laminated paper is deformed. Second, the preheating can also reduce the heat required for heat sealing by the heat cutter body 6. Third, the air flow is blown to the bent position of the laminated paper to keep a stable arc at the bent position of the laminated paper, ensuring that the laminated paper can be bent smoothly, further reducing the possibility of wrinkles when the laminated paper is bent, and improving the appearance of the packaging bag.
[0030] In order to bend the two sides of the laminated paper upwards to facilitate heat sealing of the sides, refer to Figure 7The guide assembly 8 includes a cross bar 81 fixedly connected to the side plate 7, and two limit blocks 82 are fixedly connected to the outside of the cross bar 81. One side of the limit block 82 is provided with an inclined rod 83 with one end passing through the limit block 82. The bottom of the inclined rod 83 is fixedly connected to an arc rod 84 extending to the middle area of the conveying platform 5, and the bottom of the arc rod 84 is fixedly connected to a short rod 85. When in use, the laminated paper moves from the inner side of the two arc rods 84, gradually moves inward along the trajectory of the arc rods 84, until the two sides of the laminated paper move to the short rod 85. At this time, the distance between the two sides of the laminated paper is the shortest, which is convenient for the subsequent heat sealing of the sides of the laminated paper.
[0031] To heat seal the sides of the laminated paper, refer to Figure 7 The top heat sealing component 9 includes a positioning plate 91 fixedly connected to the side plate 7, and both ends of one side of the positioning plate 91 are fixedly connected with limiting wheels 92 for limiting the position of the two sides of the laminated paper. A cross frame 93 fixed to the positioning plate 91 is installed between the two limiting wheels 92, and an electric heating plate 94 is fixedly connected to the bottom of the cross frame 93. When in use, the two sides of the laminated paper are bent upward by the guide component 8, and then pass through between the limiting wheels 92 to make the two sides of the laminated paper close together, and then pass through between the electric heating plates 94, and the electric heating plates 94 heat-seal the sides of the laminated paper.
[0032] In order to facilitate the continuous processing of laminated paper into packaging bags, refer to Figure 7 A discharge column 17 and a plurality of guide rods 18 are fixedly connected to one side of the side plate 7. A laminated paper roll 19 is sleeved on the outside of the discharge column 17. One end of the laminated paper roll 19 is slidably connected to the guide rod 18. When in use, the laminated paper roll 19 is sleeved on the discharge column 17, and one end of the laminated paper passes around the guide rod 18 and moves to the conveying platform 5, and then is conveyed forward by the conveying platform 5, so that the laminated paper can continuously pass through the hot cutting machine body 6 and be processed into packaging bags.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
