Description

Technical Field

[0001] The present invention belongs to the technical field of packaging bag manufacturing, and particularly relates to a high-strength antibacterial non-woven fabric packaging bag and a preparation device thereof. Background Art

[0002] A packaging bag refers to a bag used for packaging various articles, which facilitates the transportation of goods during the production and circulation process and is easy to store. It is widely used in daily life and industrial production. Non-woven fabric, also known as non-woven cloth, is composed of oriented or random fibers and is called cloth because of its cloth appearance and certain properties. Non-woven fabric has the characteristics of moisture-proof, breathable, flexible, light in weight, non-flammable, easy to decompose, non-toxic, non-irritating, rich in colors, low in price, recyclable, etc.

[0003] However, the existing packaging bags lack production equipment using non-woven fabric as raw material, and the production efficiency is relatively low. At the same time, the existing packaging bags cannot adjust the handle height according to the user's height. The handle is too long, and the bottom of the packaging bag is easy to contact the ground during the moving process, resulting in greater physical exertion.

[0004] Therefore, there is an urgent need to provide a high-strength antibacterial non-woven fabric packaging bag and a preparation device thereof to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a high-strength antibacterial non-woven fabric packaging bag and a preparation device thereof.

[0006] The technical solution adopted to solve the above technical problem is: to provide a high-strength antibacterial non-woven fabric packaging bag preparation device, including a support table, on one side of which an inlet mechanism is fixedly installed, and a conveying mechanism is fixedly installed inside the support table. It also includes;

[0007] A pressing mechanism is fixedly installed inside the support table, a flipping mechanism is rotatably connected inside the support table, a plurality of heat-sealing mechanisms are fixedly installed inside the support table, and a shaping block is fixedly installed inside the support table.

[0008] The present invention is further configured as: the support table is provided in two groups, a material conveying pipe is provided inside the support table, and a connecting frame is fixedly connected between the two groups of support tables.

[0009] Through the above technical solution, the two groups of support tables and the connecting frame form the overall device. The inlet mechanism conveys the raw material through the material conveying pipe to the pressing mechanism for pressing treatment of the raw material, thus facilitating the subsequent manufacture of the packaging bag.

[0010] The present invention is further configured as follows: The feeding mechanism includes a feeding box, the feeding box is fixedly installed on one side of the support table, a first motor is fixedly installed on the surface of the feeding box, the output end of the first motor is drivingly connected to a reciprocating lead screw, a filter plate is threadedly connected to the surface of the reciprocating lead screw, the filter plate is slidably connected inside the feeding box, a first bevel gear is fixedly installed on the surface of the reciprocating lead screw, and a feeding port is fixedly installed on the surface of the feeding box.

[0011] Through the above technical solution, when feeding is required, raw materials are conveyed into the feeding box through the feeding port. At this time, the first motor is started, the reciprocating lead screw rotates, and the filter plate vibrates up and down to filter raw materials such as plastic short fibers and waste wood particles conveyed in. The filtered raw materials are conveyed to the pressing mechanism through the conveying mechanism for pressing treatment.

[0012] The present invention is further configured as follows: The conveying mechanism includes an auger frame, the auger frame is rotatably connected inside the conveying pipe, a second bevel gear is fixedly installed at the end of the auger frame, and the first bevel gear meshes with the second bevel gear.

[0013] Through the above technical solution, when the reciprocating lead screw rotates, due to the meshing of the first bevel gear and the second bevel gear, the filter plate filters while the auger frame can rotate, and the filtered raw materials can be evenly conveyed to the pressing mechanism.

[0014] The present invention is further configured as follows: The pressing mechanism includes a first cylinder, the first cylinder is fixedly installed on the surface of the support table, and a pressing plate is fixedly installed at the end of the first cylinder.

[0015] Through the above technical solution, the filtered raw materials are conveyed to the position of the pressing mechanism. The first cylinder is started, and the pressing plate moves down to press the raw materials, so that the raw materials can be rolled and integrated into a non-woven fabric sheet.

[0016] The present invention is further configured as follows: The flipping mechanism includes a second motor, the second motor is fixedly installed on the surface of the support table, the output end of the second motor is drivingly connected to a rotating rod, a flipping plate is fixedly installed on the surface of the rotating rod, the flipping plate is rotatably connected inside the connecting frame, a baffle is fixedly installed on the surface of the flipping plate, and the pressing plate is movably attached to the surface of the flipping plate.

[0017] Through the above technical solution, in the initial state, the raw materials are piled up on the surface of the flipping plate and pressed by the pressing plate. After the raw materials form a sheet, the second motor is started, the rotating rod rotates, thereby driving the flipping plate to rotate, so that the non-woven fabric sheet can be driven to flip until it fits the surface of the shaping block. The setting of the baffle fixes the size of the non-woven fabric sheet, and the size of the pressing plate is the same as the size from one end of the flipping plate to the position of the baffle.

[0018] The present invention is further configured such that: the heat-sealing mechanism includes three groups of second cylinders, two of the second cylinders are fixedly installed inside the support table, one of the second cylinders is fixedly installed on the upper surface of the connecting frame, a moving plate is fixedly installed at the end of the second cylinder, a soldering iron is fixedly installed on the surface of the moving plate, and the soldering iron is in movable contact with the surface of the shaping block.

[0019] Through the above technical solution, when the turning plate turns the non-woven fabric sheet to fit with the surface of the shaping block, the left and right two second cylinders are started. At this time, the moving plate moves. Since the moving plate is set in a "C" shape, the two ends of the moving plate squeeze the two ends of the non-woven fabric sheet, so that the two ends of the two non-woven fabric sheets are fitted. At this time, the soldering iron heats the joint of the two ends of the non-woven fabric sheet, so that the two non-woven fabric sheets form an integral body. After taking out another pre-pressed non-woven fabric sheet and placing it on the top of the shaping block, the upper second cylinder is started, so that another non-woven fabric sheet and the two non-woven fabric sheets form a whole packaging bag.

[0020] A high-strength antibacterial non-woven fabric packaging bag, including a packaging bag, the inner wall of the packaging bag is in movable contact with the surface of the shaping block, symmetric fixing blocks are fixedly installed on the surface of the packaging bag, a handle is slidably connected inside each of the two fixing blocks, a drawstring is fixedly installed on the surface of one of the fixing blocks, and the other end of the drawstring is slidably connected inside the other fixing block.

[0021] Through the above technical solution, the packaging bag can be lifted and moved through the setting of the handle. After the packaging bag is filled with items, the drawstring is pulled to close the opening of the packaging bag, thereby preventing the items from slipping and playing a protective role for the items. The setting of the fixing block enables the height of the handle to be adjusted, and at the same time enables the other end of the drawstring to be fixed, avoiding the drawstring from falling off due to the extrusion of the items.

[0022] The present invention is further configured such that: symmetric positioning rods are slidably connected to the surface of the fixing block, a plurality of adjustment holes are formed on the surface of the handle, a plurality of positioning holes are formed on the surface of the drawstring, and the positioning rods are movably inserted into the adjustment holes and the positioning holes.

[0023] Through the above technical solution, before the items are placed, the height of the handle is adjusted according to the height of the user first. When the items are placed inside the packaging bag, the other end of the drawstring is pulled to effectively tighten the items with the drawstring. After the effective height of the handle and the effective length of the drawstring are determined at the same time, at this time, by inserting the positioning rods into the adjustment holes and the positioning holes, the handle and the drawstring can be limited at the same time, thus facilitating the movement and use of the packaging bag.

[0024] The present invention is further configured such that: a positioning ring is fixedly installed on the surface of the positioning rod, a positioning groove is formed inside the fixed block, the positioning rod and the positioning ring are both slidably connected inside the positioning groove, a spring is fixedly installed on the surface of the positioning ring, the other end of the spring is fixedly connected to the other side of the positioning groove, the positioning rod penetrates through the inside of the spring, a first through groove is formed on the surface of the other fixed block, the other end of the strap is slidably connected inside the first through groove, and second through grooves are formed on the surfaces of both fixed blocks, and the handle is slidably connected inside the second through grooves.

[0025] Through the above technical solution, before adjustment, the positioning rod is moved out inside the positioning groove. At this time, the positioning ring presses the spring, and the spring is in a contracted state. After the positions of the handle and the strap are determined, the positioning rod is released, the spring pressure is cancelled, and under the restoring action of the spring, the positioning rod is inserted into the adjustment hole and the positioning hole to fix the positions of the handle and the strap. The setting of the first through groove facilitates the movement and stretching of the other end of the strap, and the setting of the second through groove facilitates the movement and adjustment of the handle.

[0026] The beneficial effects of the present invention are as follows:

[0027] 1. The non-woven fabric packaging bag manufacturing device of the present invention is provided with a pressing mechanism and a heat-sealing mechanism. The pressing mechanism presses raw materials such as plastic short fibers and waste wood particles to form a non-woven fabric sheet. After the non-woven fabric sheet fits on the surface of the shaping block, the heat-sealing mechanism presses the non-woven fabric sheet to combine two non-woven fabric sheets into a whole, thereby forming a packaging bag and realizing the rapid production of the packaging bag;

Detailed implementation manners

[0038] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] Please refer to Figures 1-8 , this application provides a device for preparing a high-strength antibacterial non-woven fabric packaging bag, including a support platform 1, a feeding mechanism 2 is fixedly installed on one side of the support platform 1, and a conveying mechanism 3 is fixedly installed inside the support platform 1.

[0040] As Figure 2 shown, the support platform 1 is provided in two groups, a material conveying pipe 11 is opened inside the support platform 1, and a connecting frame 12 is fixedly connected between the two groups of support platforms 1.

[0041] In this embodiment, further, the two groups of support platforms 1 and the connecting frame 12 form the overall device, and the feeding mechanism 2 conveys the raw materials to the pressing mechanism 4 through the material conveying pipe 11 for pressing the raw materials, so as to facilitate the subsequent manufacture of the packaging bag 8.

[0042] As Figure 1 shown in Figure 6As shown in the figure, the feeding mechanism 2 includes a feeding box 21. The feeding box 21 is fixedly installed on one side of the support platform 1. A first motor 22 is fixedly installed on the surface of the feeding box 21. The output end of the first motor 22 is drivingly connected to a reciprocating lead screw 23. A filter plate 24 is threadedly connected to the surface of the reciprocating lead screw 23. The filter plate 24 is slidably connected inside the feeding box 21. A first bevel gear 25 is fixedly installed on the surface of the reciprocating lead screw 23. A feeding port 26 is fixedly installed on the surface of the feeding box 21.

[0043] In this embodiment, further, when feeding is required, the raw materials are conveyed into the feeding box 21 through the feeding port 26. At this time, the first motor 22 is started, the reciprocating lead screw 23 rotates, and the filter plate 24 vibrates up and down to filter the conveyed raw materials such as plastic short fibers and waste wood particles. The filtered raw materials are conveyed to the pressing mechanism 4 by the conveying mechanism 3 for pressing treatment.

[0044] As Figure 2 shown in Figure 6 the figure, the conveying mechanism 3 includes an auger frame 31. The auger frame 31 is rotatably connected inside the conveying pipe 11. A second bevel gear 32 is fixedly installed at the end of the auger frame 31. The first bevel gear 25 meshes with the second bevel gear 32.

[0045] In this embodiment, further, when the reciprocating lead screw 23 rotates, through the meshing action of the first bevel gear 25 and the second bevel gear 32, the filter plate 24 filters while the auger frame 31 can rotate, and the filtered raw materials can be evenly conveyed to the pressing mechanism 4.

[0046] A pressing mechanism 4 is fixedly installed inside the support platform 1. A flipping mechanism 5 is rotatably connected inside the support platform 1. A plurality of heat-sealing mechanisms 6 are fixedly installed inside the support platform 1. A shaping block 7 is fixedly installed inside the support platform 1.

[0047] As Figure 1 shown in Figure 2 the figure, the pressing mechanism 4 includes a first cylinder 41. The first cylinder 41 is fixedly installed on the surface of the support platform 1. A pressing plate 42 is fixedly installed at the end of the first cylinder 41.

[0048] In this embodiment, further, when the filtered raw materials are conveyed to the position of the pressing mechanism 4, the first cylinder 41 is started, and the pressing plate 42 moves down to press the raw materials, so that the raw materials can be rolled and integrated into a non-woven fabric sheet.

[0049] As Figure 2 shown in Figure 7As shown in the figure, the flipping mechanism 5 includes a second motor 51. The second motor 51 is fixedly installed on the surface of the support platform 1. The output end of the second motor 51 is drivingly connected to a rotating rod 52. A flipping plate 53 is fixedly installed on the surface of the rotating rod 52. The flipping plate 53 is rotatably connected inside the connecting frame 12. A baffle 54 is fixedly installed on the surface of the flipping plate 53. The pressing plate 42 is movably attached to the surface of the flipping plate 53.

[0050] In this embodiment, further, in the initial state, the raw materials are stacked on the surface of the flipping plate 53 and pressed by the pressing plate 42. After the raw materials form a thin sheet, the second motor 51 is started, and the rotating rod 52 rotates, thereby driving the flipping plate 53 to rotate, so that the non-woven fabric thin sheet can be driven to flip until it fits against the surface of the shaping block 7. The setting of the baffle 54 fixes the size of the non-woven fabric thin sheet. The size of the pressing plate 42 is the same as the size from one end of the flipping plate 53 to the position of the baffle 54.

[0051] As Figure 2 shown in Figure 3 As shown in the figure, the heat-sealing mechanism 6 includes three groups of second air cylinders 61. Two second air cylinders 61 are fixedly installed inside the support platform 1, and one second air cylinder 61 is fixedly installed on the upper surface of the connecting frame 12. A moving plate 62 is fixedly installed at the end of the second air cylinder 61. An electric soldering iron 63 is fixedly installed on the surface of the moving plate 62. The electric soldering iron 63 is movably attached to the surface of the shaping block 7.

[0052] In this embodiment, further, when the flipping plate 53 flips the non-woven fabric thin sheet until it fits against the surface of the shaping block 7, the left and right two second air cylinders 61 are started. At this time, the moving plate 62 moves. Since the moving plate 62 is set in a "C" shape, the two ends of the moving plate 62 squeeze the two ends of the non-woven fabric thin sheet, so that the two ends of the two non-woven fabric thin sheets fit together. At this time, the electric soldering iron 63 heats the joint of the two ends of the non-woven fabric thin sheet to form a whole of the two non-woven fabric thin sheets. Then, another pre-pressed non-woven fabric thin sheet is taken out and placed on the top of the shaping block 7, and the upper second air cylinder 61 is started to form a whole packaging bag 8 with the other two non-woven fabric thin sheets.

[0053] As Figure 5 shown in the figure, a high-strength antibacterial non-woven fabric packaging bag includes a packaging bag 8. The inner wall of the packaging bag 8 is movably attached to the surface of the shaping block 7. Symmetrical fixing blocks 83 are fixedly installed on the surface of the packaging bag 8. A handle 81 is slidably connected inside both fixing blocks 83. A drawstring 82 is fixedly installed on the surface of one fixing block 83, and the other end of the drawstring 82 is slidably connected inside the other fixing block 83.

[0054] Further in this embodiment, the handle 81 is provided to lift and move the packaging bag 8. After the packaging bag 8 is filled with items, the opening of the packaging bag 8 can be closed by pulling the drawstring 82, thereby preventing the items from slipping and playing a protective role for the items. The setting of the fixing block 83 enables the height of the handle 81 to be adjusted, and at the same time enables the other end of the drawstring 82 to be fixed, avoiding the drawstring 82 from falling off due to extrusion by the items.

[0055] As Figure 5 shown in Figure 8 FIG. 7, symmetric positioning rods 831 are slidably connected to the surface of the fixing block 83. A plurality of adjustment holes 811 are formed on the surface of the handle 81, and a plurality of positioning holes 821 are formed on the surface of the drawstring 82. The positioning rods 831 are movably inserted into the adjustment holes 811 and the positioning holes 821.

[0056] Further in this embodiment, before placing the items, first adjust the height of the handle 81 according to the user's height. When the items are placed inside the packaging bag 8, pull the other end of the drawstring 82 to effectively tighten the items with the drawstring 82. After the effective height of the handle 81 and the effective length of the drawstring 82 are determined, at this time, by inserting the positioning rods 831 into the adjustment holes 811 and the positioning holes 821, the handle 81 and the drawstring 82 can be simultaneously limited, thus facilitating the movement and use of the packaging bag 8.

[0057] As Figure 8 shown in

[0058] Further in this embodiment, before adjustment, move the positioning rod 831 out of the positioning groove 833 inside. At this time, the positioning ring 832 presses the spring 834, and the spring 834 is in a contracted state. After the positions of the handle 81 and the drawstring 82 are determined, release the positioning rod 831. The pressure of the spring 834 is cancelled. Under the restoring action of the spring 834, the positioning rod 831 is inserted into the adjustment holes 811 and the positioning holes 821 to fix the positions of the handle 81 and the drawstring 82. The setting of the first through groove 835 facilitates the movement and stretching of the other end of the drawstring 82, and the setting of the second through groove 836 facilitates the movement and adjustment of the handle 81.

[0059] The working principle of this embodiment is as follows. First, the raw materials are conveyed into the feeding box 21 through the feeding port 26. At this time, the first motor 22 is started, and the reciprocating lead screw 23 rotates. The filter plate 24 vibrates up and down to filter the conveyed raw materials such as plastic short fibers and waste wood particles. The filtered raw materials are conveyed to the surface of the turning plate 53 through the auger frame 31. The first cylinder 41 is started, and the pressing plate 42 moves downward to press the raw materials, so that the raw materials can be rolled and integrated into a non-woven fabric sheet. At this time, the second motor 51 is started, and the rotating rod 52 rotates, thereby driving the turning plate 53 to rotate, so that the non-woven fabric sheet can be driven to turn until it fits the surface of the shaping block 7. Finally, the left and right second cylinders 61 are started. At this time, the moving plate 62 moves, and the two ends of the moving plate 62 squeeze the two ends of the non-woven fabric sheet, so that the two ends of the two non-woven fabric sheets fit together. At this time, the electric soldering iron 63 heats the joint of the two ends of the non-woven fabric sheet, so that the two non-woven fabric sheets form a whole. Then, take out another pre-pressed non-woven fabric sheet and place it on the top of the shaping block 7. Start the upper second cylinder 61, and the other non-woven fabric sheet and the two non-woven fabric sheets can form the whole packaging bag 8.

[0060] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
