Description

Technical Field

[0001] This invention belongs to the field of tote bag production technology, and in particular relates to a production method and equipment for preparing a sealed tote bag. Background Technology

[0002] A tote bag is a simple bag made from materials such as paper, PVC holographic film, non-woven fabric, and industrial cardboard. It is commonly used by manufacturers to hold products; it is also used to hold gifts; many fashionable Westerners use tote bags as handbags to match other outfits. Tote bags are also called handle bags or handbags. The production process of tote bags usually involves the use of various chemical agents, resulting in a significant amount of chemical residue on the surface of the bags before they leave the factory. Therefore, they need to be neutralized and disinfected with disinfectants to ensure safe use. Existing disinfection methods include immersion and spraying. Immersion requires a large chemical tank, and the tote bags are dried after immersion. However, this method often leaves a large amount of disinfectant residue on the surface of the tote bags, which can become another source of toxicity after disinfection. Existing spray disinfection systems often release large amounts of disinfectant into the air during spraying, resulting in significant waste and failing to meet usage requirements. Summary of the Invention

[0003] The purpose of this invention is to provide a production device for manufacturing self-sealing tote bags, aiming to solve the technical problems in the prior art.

[0004] To achieve the above objectives, this invention provides a production equipment for manufacturing self-sealing tote bags, including an adhesive applicator, a spraying mechanism, a drying mechanism, and a conveyor belt connecting the adhesive applicator, the spraying mechanism, and the drying mechanism. The conveyor belt transports tote bags located on it. The spraying mechanism includes two symmetrically arranged spray frames with a passage between them for the tote bags to pass through. The passage is connected to the conveyor belt. Each spray frame includes a drive roller and at least two sets of spray cylinders for spraying. The spray cylinders are engaged by teeth disposed on their outer walls, which do not contact the tote bags. Each spray cylinder has a pressure chamber and several spray pipes communicating with the pressure chamber. The pressure chamber is filled with disinfectant. The spray pipes are evenly distributed on the outer wall of the spray cylinder. A metering spray structure is coaxially and rollingly connected to the inner wall of the pressure chamber. The metering spray structure is sealed to the end of each spray pipe near the pressure chamber and has at least one opening for connecting the pressure chamber and the spray pipes. The opening is movably connected to each spray pipe. By rotating the spray cylinder, each spray pipe alternately connects to the opening to achieve metered spraying and leave a uniform spray area on the tote bag. Due to the meshing action between the spray cylinders, after the tote bag passes through one spray cylinder and leaves a spray area, when it passes through another spray cylinder meshing with the same spray cylinder, the unsprayed area is sprayed again, achieving thorough disinfection of the tote bag surface.

[0005] Preferably, the quantitative spraying structure is a hollow cylinder that is rolledly connected to the inner wall of the pressure chamber. The outer wall of the hollow cylinder is rolledly fitted with the inner wall of the pressure chamber. The hollow cylinder is filled with disinfectant. One end of the hollow cylinder extends outward and is fixedly installed with the spray frame. The other end is provided with a pressurizing pipe for filling the hollow cylinder with disinfectant. When the spray cylinder rotates, it rotates about the hollow cylinder as a fixed axis.

[0006] Preferably, the spray frame is provided with a fixed seat that is rotatably connected to the spray cylinder, the outward extension of the hollow cylinder is fixedly connected to the fixed seat, the outward extension of the hollow cylinder is a completely sealed closed cylinder and a fixed shaft for connecting the sealed cylinder and the fixed seat.

[0007] Preferably, the spray cylinder is provided with a drive motor on the side away from the fixed base, and the drive motor is used to drive the spray cylinder to rotate around the hollow cylinder body.

[0008] Preferably, the opening is opened towards the side closer to the passage, so that when the spray pipe moves to a position close to the passage, the disinfectant in the pressure chamber flows through the opening into the spray pipe and is sprayed outward.

[0009] Preferably, several of the spray pipes pass through the middle of each of the teeth and are located at the movable end of the teeth and communicate outwards.

[0010] Preferably, the spray pipe is disposed in the groove between two adjacent teeth and communicates outward.

[0011] Preferably, the drying mechanism includes a drying rack and a drying station. The drying rack is equipped with a lifting motor, the output shaft of which is connected to a pressure plate and drives the pressure plate to move up and down. An air cavity is formed inside the pressure plate, and an air hole extends downward from the bottom of the air cavity. A hot air blower is provided at the top of the air cavity to blow hot air into the air cavity, through the air hole, and towards the drying station. One end of the drying station is connected to the conveyor belt and is used to receive the tote bags conveyed by the conveyor belt.

[0012] Preferably, at least one set of heating rollers is provided at each end of the drying station for conveying the tote bag and heating the surface of the tote bag, and the pressure plate moves up and down between two adjacent heating rollers.

[0013] This invention also proposes a method for producing tote bags using the aforementioned production equipment for self-sealing tote bags, comprising the following steps:

[0014] Step S1: Place the semi-finished tote bag into the conveyor belt, and convey it to the adhesive application section for adhesive application to form a seal inside the tote bag. After adhesive application, convey it to the spraying mechanism for spraying disinfection.

[0015] Step S2: After the tote bag enters the spraying mechanism, it enters the passage and is captured by the drive roller and conveyed to the bottom of the spray cylinder. The drive motor drives the spray cylinder to rotate around the hollow cylinder. At the same time, the spray pipes distributed on the outer wall of the spray cylinder rotate with the spray cylinder. When the spray pipe rotates to the opening in the hollow cylinder, the disinfectant in the pressure chamber passes through the opening and enters the spray pipe and sprays the tote bag below. After the tote bag passes through several sets of spray cylinders, the surface of the tote bag is evenly coated with disinfectant. Then, it is transported out of the spraying mechanism by the drive roller, enters the conveyor belt, and enters the drying mechanism.

[0016] Step S3: After the tote bag enters the drying mechanism, it is preheated by the heating roller and then conveyed into the drying station. The lifting motor drives the pressure plate to press down, and the hot air blows hot air into the air chamber. The hot air passes through the air hole and blows onto the tote bag located at the drying station for drying. After completion, it is captured by the heating roller located at the other end of the drying station for final heating and then conveyed out of the drying station and onto the conveyor belt for transport.

[0017] The production method and equipment for preparing sealed tote bags provided in this embodiment of the invention have at least one of the following technical effects:

[0018] In use, the semi-finished tote bag is placed into the conveyor belt and conveyed to the adhesive application section for adhesive application to form a seal inside the tote bag. After adhesive application, it is conveyed to the spraying mechanism for disinfection. After entering the spraying mechanism, it enters the passage and is captured by the drive roller and conveyed to the bottom of the spray cylinder. The drive motor drives the spray cylinder to rotate around the hollow cylinder body. At the same time, the spray pipes distributed on the outer wall of the spray cylinder rotate with the spray cylinder. When the spray pipe rotates to the opening of the hollow cylinder body, the disinfectant in the pressure chamber passes through. The spray nozzle enters the spray pipe and sprays the bag downwards. During this process, a spray cylinder rotates, causing the spray pipe on the spray cylinder to spray the surface of the bag into several spray zones with fixed intervals. By setting up interlocking between two adjacent spray cylinders, the bag can be sprayed on areas that have not been sprayed when it passes through another spray cylinder, so that the surface of the bag is evenly coated with disinfectant. Then, it is driven by a roller to be transported out of the spraying mechanism, enters the conveyor belt, and enters the drying mechanism for drying. This saves disinfectant, reduces waste, and lowers production costs. Attached Figure Description

The following description is based on the accompanying drawings. Figures 1-6 The described embodiments are exemplary and intended to explain embodiments of the invention, and should not be construed as limiting the invention.

Therefore, they should not be construed as limitations on the present invention.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0040] In one embodiment of the present invention, such as Figures 1-6As shown, a production device for manufacturing self-sealing tote bags is provided, characterized by: including an adhesive applicator 1, a spraying mechanism 2, a drying mechanism 3, and a conveyor belt 10 for connecting the adhesive applicator 1, the spraying mechanism 2, and the drying mechanism 3. The conveyor belt 10 is used to transport tote bags located on the conveyor belt 10. The spraying mechanism 2 includes two symmetrically arranged spray frames 21, with a passage 22 between the two spray frames 21 for allowing the tote bags to pass through. The passage 22 is connected to the conveyor belt 10. Each spray frame 21 includes a drive roller 211 and at least two sets of spray cylinders 23 for spraying. Each spray cylinder 23 is engaged by teeth 231 disposed on the outer wall of the spray cylinder 23. The teeth 231 do not contact the tote bags. A pressure chamber 232 is opened inside the spray cylinder 23, and a plurality of spray pipes 233 are connected to the pressure chamber 232. The cavity 232 is filled with disinfectant. The spray pipes 233 are evenly distributed on the outer wall of the spray cylinder 23. The inner wall of the pressure cavity 232 is coaxially and rotatably connected to a metering spray structure. The metering spray structure is sealed to the end of each spray pipe 233 near the pressure cavity 232, and has at least one opening 241 for connecting the pressure cavity 232 and the spray pipes 233. The opening 241 is movably connected to each spray pipe 233. By rotating the spray cylinder 23, each spray pipe 233 alternately connects to the opening 241 to achieve metered spraying and leave a uniform spray area on the tote bag. Due to the meshing action between the spray cylinders 23, after the tote bag passes through one spray cylinder 23 and leaves a spray area, when it passes through another spray cylinder 23 that meshes with the same spray cylinder 23, the unsprayed area is sprayed again, so as to achieve full spray disinfection of the surface of the tote bag.

[0041] Furthermore, the quantitative spraying structure is a hollow cylinder 24 that is rolledly connected to the inner wall of the pressure chamber 232. The outer wall of the hollow cylinder 24 is rolledly fitted with the inner wall of the pressure chamber 232. The hollow cylinder 24 is filled with disinfectant. One end of the hollow cylinder 24 extends outward and is fixedly installed with the spray frame 21. The other end is provided with a pressurizing pipe 242 for filling the hollow cylinder 24 with disinfectant. When the spray cylinder 23 rotates, it rotates about the hollow cylinder 24 as an axis. Specifically, the hollow cylinder 24 remains stationary, while the spray pipe 23 rotates around the hollow cylinder 24. When the spray pipe 233 continues to rotate and disconnects from the opening 241, i.e., when the opening 241 is blocked by the inner wall of the pressure chamber 232, the pressurization pipe 242 continues to inject disinfectant into the pressure chamber 232 to increase the pressure inside the pressure chamber 232. When any spray pipe 233 rotates to the opening 241 of the hollow cylinder 24, the disinfectant in the pressure chamber 232 passes through the opening 241 and enters the spray pipe 233 to spray outwards. Due to the high pressure inside the pressure chamber 232, the disinfectant sprays outwards with greater force, achieving a better spraying effect.

[0042] Furthermore, the spray frame 21 is provided with a fixed base 212 rotatably connected to the spray cylinder 23. The outward extension of the hollow cylinder 24 is fixedly connected to the fixed base 212. The outward extension of the hollow cylinder 24 is a completely sealed cylinder 243, and a fixed shaft 244 is used to connect the sealed cylinder 243 and the fixed base 212. Specifically, the sealed cylinder 243 and the fixed base 212 are connected by the fixed shaft 244, and the fixed shaft 244 and the hollow cylinder 24 are connected by the sealed cylinder 243. When the spray cylinder 23 rotates, the hollow cylinder 24 remains stationary, and the spray cylinder 23 rotates around the hollow cylinder 24, achieving a better rotation effect.

[0043] Furthermore, the spray cylinder 23 is equipped with a drive motor 234 on the side away from the fixed base 212. The drive motor 234 is used to drive the spray cylinder 23 to rotate around the hollow cylinder 24. Specifically, when the spray cylinder 23 rotates, the drive motor 234 drives the spray cylinder 23 on the side away from the fixed base 212 to achieve a better driving effect. More specifically, the drive motor 234 can drive the transmission belt to drive the spray cylinder 23 to rotate. The transmission belt can drive the motor 234 to simultaneously drive the spray cylinders 23 respectively set on the two spray frames 21 to achieve a better driving effect.

[0044] Furthermore, the opening 241 opens towards the side closer to the passage 22, allowing the disinfectant in the pressure chamber 232 to flow through the opening 241 into the spray pipe 233 and spray outwards when the spray pipe 233 moves to a position close to the passage 22. Specifically, when any spray pipe 233 rotates to the opening 241 of the hollow cylinder 24, the disinfectant in the pressure chamber 232 passes through the opening 241 into the spray pipe 233 and sprays outwards. By setting the opening 241 to open towards the side closer to the passage 22, more precise spraying and a shorter spraying distance for the disinfectant can be achieved, reducing the amount of disinfectant dispersed in the air, reducing waste, improving accuracy, and achieving a better spraying effect.

[0045] Furthermore, several spray pipes 233 respectively penetrate the middle of each of the teeth 231 and are connected outwards at the movable end of the teeth 231. Specifically, when any spray pipe 233 rotates to the opening 241 of the hollow cylinder 24, the disinfectant in the pressure chamber 232 passes through the opening 241 and enters the spray pipe 233 for spraying outwards. Due to the high pressure in the pressure chamber 232, the disinfectant is sprayed outwards with greater force. By having the spray pipes 233 penetrate the middle of each of the teeth 231 and be connected outwards at the movable end of the teeth 231, the distance between the outward connection point of the spray pipe 233 and the bag can be shortened when the spray pipe 233 is connected to the opening 241, further improving the accuracy of spraying and shortening the flight distance of the disinfectant during spraying.

[0046] Furthermore, the spray pipe 233 is disposed within the groove between two adjacent teeth 231 and communicates outward. Specifically, when any spray pipe 233 rotates to the opening 241 of the hollow cylinder 24, the disinfectant in the pressure chamber 232 passes through the opening 241 and enters the spray pipe 233 for outward spraying. Due to the high pressure in the pressure chamber 232, the disinfectant is sprayed outward with greater force. By disposing the spray pipe 233 within the groove between two adjacent teeth 231 and communicating outward, the disinfectant is restricted by the two teeth 231 when spraying outward, reducing outward diffusion and improving the accuracy of spraying.

[0047] Furthermore, the drying mechanism 3 includes a drying rack 31 and a drying station 32. The drying rack 31 is equipped with a lifting motor 33, the output shaft of which is connected to a pressure plate 34, driving the pressure plate 34 to move up and down. An air cavity 341 is formed inside the pressure plate 34, and an air hole 342 extends downward from the bottom of the air cavity 341. A hot air blower 343 is installed at the top of the air cavity 341 to blow hot air into the air cavity 341, which then passes through the air hole 342 and blows towards the drying station 32. One end of the drying station 32 is connected to the conveyor belt 10 and is used to receive the tote bags conveyed by the conveyor belt 10. Specifically, after the tote bags enter the drying mechanism 3, the lifting motor 33 drives the pressure plate 34 to press down, and the hot air blows hot air into the air cavity 341. The hot air passes through the air hole 342 and blows towards the tote bags located at the drying station 32 for drying, achieving a better drying effect.

[0048] Furthermore, at least one set of heating rollers 321 are respectively provided at both ends of the drying station 32 for conveying the tote bags and heating their surfaces. The pressure plate 34 moves up and down between two adjacent heating rollers 321. After being heated by the heating rollers 321, the tote bags enter the drying station 32. The pressure plate 34 is then pressed down by the lifting motor 33. The hot air blows hot air into the air chamber 341 and through the air holes 342 to dry the tote bags located in the drying station 32. The tote bags preheated by the heating rollers 321 rise in temperature faster when dried by the hot air blower, reducing drying time and improving production efficiency.

[0049] Production equipment based on the aforementioned self-sealing tote bags, such as Figures 1-6 The method also includes the following steps:

[0050] Step S1: Place the semi-finished tote bag into the conveyor belt 10, and convey it to the adhesive application section 1 for adhesive application to form a seal inside the tote bag. After adhesive application, convey it to the spraying mechanism 2 for spraying disinfection via the conveyor belt 10.

[0051] Step S2: After the tote bag enters the spraying mechanism 2, it enters the passage 22 and is captured by the drive roller 211 and continues to be conveyed to the bottom of the spraying cylinder 23. The drive motor 234 drives the spraying cylinder 23 to rotate around the hollow cylinder 24. At the same time, the spray pipes 233 distributed on the outer wall of the spraying cylinder 23 rotate with the spraying cylinder 23. When the spray pipes 233 rotate to the opening 241 of the hollow cylinder 24, the disinfectant in the pressure chamber 232 passes through the opening 241 and enters the spray pipes 233 and sprays the tote bag below. After the tote bag passes through several sets of spraying cylinders 23, the surface of the tote bag is evenly coated with disinfectant. Then, it is transported out of the spraying mechanism 2 by the drive roller 211, enters the conveyor belt 10, and enters the drying mechanism 3.

[0052] Step S3: After the tote bag enters the drying mechanism 3, it is captured by the heating roller 321 for initial preheating and then conveyed into the drying station 32. The lifting motor 33 drives the pressure plate 34 to press down, and the hot air blower 343 blows hot air into the air chamber 341. The hot air passes through the air hole 342 and blows onto the tote bag located at the drying station 32 for drying. After completion, it is captured by the heating roller 321 located at the other end of the drying station 32 for final heating and then conveyed out of the drying station 32 and onto the conveyor belt 10 for transport.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
