Description

Technical Field

[0001] The invention relates to the technical field of canning and sealing, and in particular to a double-linked bag fully automatic filling, sealing and forming integrated machine and a double-linked packaging bag. Background Art

[0002] Double packaging bags refer to the design of two packaging bags connected or used together. This kind of packaging bag is usually designed with a specific connection structure or separation area, which can package two related or complementary products, or materials that need to be stored separately but must be used together, to ensure the sealing of the products and facilitate consumers to use. It has been widely used in the food, cosmetics and daily product industries, such as instant oatmeal and milk powder in the food industry, toner and lotion in the cosmetics industry, and hair washing and dyeing products that need to be stored separately and used together.

[0003] At present, the existing packaging generally uses film bags to package products, and the product states include aqueous solutions, powders, granules and colloidal materials. Generally, the packaging process includes unwinding, film feeding, bag filling, sealing, shearing and other process steps. However, the double-linked packaging bag products produced by the existing equipment are mostly in the form of upper and lower separation, and some are in the form of left and right separation, which is equivalent to splicing two existing single packaging bags together. Some tearing edges are set at the upper and lower ends of the same side, and some tearing edges are set at the left and right ends. When using, each tearing edge must be torn separately, and the tearing edge is not easy to tear, which causes inconvenience to users. At the same time, with the development of technology, the film feeding speed is getting faster and faster. The existing equipment cannot adapt to the requirements of high-speed film feeding, and it is easy to have problems such as film backflow and poor sealing quality.

[0004] Therefore, it is urgent to design a double-bag fully automatic filling and sealing forming integrated machine that can adapt to the requirements of high-speed film feeding, effectively prevent film rotation, and realize double-bag packaging through three-side sealing, with good sealing quality, and complete the fully automated production from film feeding to cutting, with a simple and compact structure. At the same time, the double-bag packaging bags produced by the integrated machine can not only pack different materials, especially for materials that need to be stored separately but must be mixed, but also effectively reduce the number of times the tearing is required, which is simple, fast, labor-saving, and improves the convenience of user use.

DETAILED DESCRIPTION

[0030] The preferred embodiments of the present application will be described in more detail below with reference to the accompanying drawings.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0033] The double-link packaging bags produced by existing equipment generally have tearing notches set at the upper and lower ends of the same side, and some tearing notches are set at the left and right ends. When using, the tearing notches of each separator must be torn separately, and the tearing notches are not easy to tear, which causes inconvenience to users. At the same time, with the development of technology, the film feeding speed is getting faster and faster. The existing equipment cannot meet the requirements of high-speed film feeding, and it is easy to cause problems such as film backflow and poor sealing quality.

[0034] In response to the above problems, an embodiment of the present application provides a double-bag fully automatic filling, sealing and forming all-in-one machine, which can adapt to the requirements of high-speed film feeding, effectively prevent film rotation, and realize double-bag packaging through three-side sealing with good sealing quality, completing fully automated production from film feeding to cutting, and has a simple and compact structure.

[0035] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0036] Embodiment 1

[0037] See also Figure 1-Figure 6 The double-linked bag fully automatic filling, sealing and forming integrated machine of the present application comprises a frame 1, a feeding mechanism 2, a film supply mechanism 3, a bag forming mechanism 4, a longitudinal sealing mechanism 5, a transverse sealing mechanism 6 and a punching mechanism 7. The frame 1 is a frame structure, the feeding mechanism 2 is arranged above the frame 1, the film supply mechanism 3 is arranged inside the frame 1, and the bag forming mechanism 4, the longitudinal sealing mechanism 5 and the punching mechanism 7 are arranged on one side of the frame 1 from top to bottom. In order to improve the stability of the entire equipment, the frame 1 is made of stainless steel or aluminum alloy, and the four corners of the bottom end of the frame 1 are provided with standing feet.

[0038] like Figure 1-Figure 2 As shown, the unloading mechanism 2 is arranged at the top of the frame 1, and is used to provide the material to be filled, and the material is preferably a fluid material. Specifically, the unloading mechanism 2 includes a barrel 21 and a material pipe 22, and the barrel 21 is arranged at the top of the frame 1, and is used to store the material to be filled. The head end of the material pipe 22 is connected to the barrel 21, and the tail end is connected to the formed bag body, and the head end of the material pipe 22 is higher than the bottom end of the material pipe 22, so that the material in the barrel 21 can reach the tail end of the material pipe 22 from the head end of the material pipe 22, and then be filled into the bag body. It should be noted that two barrels 21 and two material pipes 22 are provided, and the materials stored in the barrel 21 can be the same material (such as shampoo in both barrels), or different materials (such as shampoo in one barrel and shower gel in another barrel).

[0039] The film supply mechanism 3 is arranged below the unloading mechanism 2 and is located on the same side of the bag forming mechanism 4, the longitudinal sealing mechanism 5, the transverse sealing mechanism 6 and the punching mechanism 7. Specifically, the film supply mechanism 3 includes a film roll mounting shaft 31, a roller bag pulling assembly, a laser coder 35 and a color mark sensor 36. The film roll mounting shaft 31 is arranged on the frame 1 and is located below the roller bag pulling assembly, and is used to place the film roll. Exemplarily, one end of the film roll mounting shaft 31 is fixed to the frame 1 through a mounting seat, and the other end is suspended and used to cover the film roll.

[0040] like Figure 2-Figure 3 As shown, the roller bag pulling assembly includes a first group of rollers 32, a second group of rollers 33 and a third group of rollers 34, which are used to flatten the roll film into a thin film. The first group of rollers 32 are staggered above the roll film mounting shaft 31, so that the path of the film is in a vertical folded line shape as a whole. Further, in order to improve the stretching flatness of the film, the film supply mechanism 3 also includes a counterweight rod 38, which can be raised and lowered above the roll film mounting shaft 31. When the film passes around the counterweight rod 38 from top to bottom, the film can be stretched and straightened by adjusting the height of the counterweight rod 38. By setting the counterweight rod 38 and cooperating with the staggered first group of rollers 32, it is possible to save space while effectively stretching and flattening the roll film, which is conducive to reducing the space occupied by the entire integrated machine. The second group of rollers 33 is horizontally arranged between the first group of rollers 32 and the third group of rollers 34, and is used to make the film parallel to the horizontal plane. The laser coder 35 is arranged below the second group of rollers 33, and the nozzle of the laser coder 35 is facing upward, so that the nozzle can be just facing the flattened film, which is convenient for coding. By horizontally arranging the second group of rollers 33, the film is in a horizontal state, and the laser coder 35 is arranged below the film, the coding quality can be improved, and the coding surface is located on the lower surface of the film. The third group of rollers 34 is arranged on one side of the bag forming mechanism 4, and is used to transfer the coded film to the bag forming mechanism 4. The color mark sensor 36 is arranged below the third group of rollers 34, and is used to detect the position of the coding, and then locate the position of the film, so that after the bag is formed, the coding content is at the preset position of the bag.

[0041] Furthermore, since the film feeding speed of the film supply mechanism 3 is too fast, in order to prevent the film from rotating, the double-link bag fully automatic filling, sealing and forming integrated machine also includes a one-way bearing 37, and the one-way bearing 37 is sleeved on the third group of rollers 34. Specifically, the third group of rollers 34 includes a first rubber roller 341 and a second rubber roller 342; the first rubber roller 341 is arranged on one side of the second group of rollers 33, and the one-way bearing 37 is sleeved on the first rubber roller 341, and the second rubber roller 342 is arranged side by side on the side of the first rubber roller 341, and a retaining ring is provided on the second rubber roller 342, and the retaining ring is in contact with the first rubber roller 341, and the film is arranged between the first rubber roller 341 and the retaining ring. By arranging the one-way bearing 37 on the first rubber roller 341 and arranging the second rubber roller 342 to be fixed, when the film is transmitted toward the bag forming mechanism 4, the first rubber roller 341 can rotate counterclockwise, thereby realizing the transmission of the film. When the film has a tendency to rotate, the first rubber roller 341 has a tendency to rotate clockwise. Under the action of the one-way bearing 37, the first rubber roller 341 cannot rotate clockwise, thereby effectively preventing the film from rotating.

[0042] The bag forming mechanism 4 is arranged at the end side of the film supply mechanism 3, and is used to initially wrap the film into a bag model. Figure 4As shown, the bag forming mechanism 4 includes a mounting frame 41, a bag former 42, a first forming tube 43 and a second forming tube 44, and the bag former 42, the first forming tube 43 and the second forming tube 44 are all fixed on the mounting frame 41. Specifically, the bag former 42 includes a first guide block 421, a second guide block 422 and a third guide block 423, the first guide block 421 and the second guide block 422 are symmetrically arranged on both sides of the third guide block 423, and form a circular channel with a notch with the third guide block 423, the first forming tube 43 and the second forming tube 44 are arranged through the circular channel, and the film is transferred to the bag former 42 by the third group of rollers 34, and moves downward along the direction of the third guide block 423, the first guide block 421 and the second guide block 422, at this time, the film is located between the bag former 42 and the first forming tube 43 and the second forming tube 44, and the side of the film with the coding is close to the bag former 42. After passing through the first guide block and the second guide block, the two sides of the film can be turned up and extended toward the middle to initially form a bag body. In order to facilitate the subsequent vertical sealing 102, so that there is a film sealing space in the middle of the bag body, the bag forming device 42 is also provided with a convex portion 424, and the convex portion 424 is arranged in the middle of the surface of the third guide block 423, and the length direction of the convex portion 424 is the up and down direction, that is, the first forming tube 43 and the second forming tube 44 are located on both sides of the convex portion 424, so that the film wrapped around the first forming tube 43 and the second forming tube 44 can subsequently form two accommodating cavities for accommodating materials. In order to simplify the structure and save space, the material tube 22 is arranged inside the first forming tube 43 and the second forming tube 44.

[0043] The longitudinal sealing mechanism 5 is arranged below the bag forming mechanism 4, and is used to vertically seal the middle of the bag body 102. Specifically, the longitudinal sealing mechanism 5 includes a longitudinal sealing substrate 51, a sealing plate 52, a longitudinal heat sealer 53 and a longitudinal sealing cylinder 54. The longitudinal sealing substrate 51 is adapted to the bag body. Exemplarily, a groove is provided on a side of the longitudinal sealing substrate 51 facing the longitudinal heat sealer 53, and the groove is used to accommodate the first forming tube 43, the second forming tube 44 and the bag body. The sealing plate 52 is arranged on one side of the longitudinal sealing substrate 51, and a gap is provided between the sealing plate 52 and the longitudinal sealing substrate 51. When the bag body is located in the groove, the sealing plate 52 moves toward the direction of the longitudinal sealing substrate 51 until the sealing plate 52 abuts against the longitudinal sealing substrate 51 and presses the bag body. The longitudinal heat sealer 53 is arranged opposite to the center line of the longitudinal sealing substrate 51 and is located below the sealing plate 52. A heating tube is provided on the longitudinal heat sealer 53, and the heating tube is used to heat the longitudinal heat sealer 53, thereby facilitating heat sealing of the film. The movable push rod of the longitudinal sealing cylinder 54 is connected to the longitudinal heat sealer 53, and the pushing direction of the longitudinal sealing cylinder 54 is toward the longitudinal sealing substrate 51. When the bag body is pressed by the sealing plate 52, the longitudinal sealing cylinder 54 extends out, driving the longitudinal heat sealer 53 to move toward the longitudinal sealing substrate 51 until the longitudinal heat sealer 53 abuts against the longitudinal sealing substrate 51, completing the middle heat sealing of the bag body. At this time, the bag body is divided into a left bag body and a right bag body, and the left bag body and the right bag body are used to contain materials respectively.

[0044] The transverse sealing mechanism 6 is arranged below the longitudinal sealing mechanism 5 and is used to transversely seal the upper and lower ends of the bag body. Figure 5 As shown, the transverse sealing mechanism 6 includes a first transverse sealing substrate 61, a second transverse sealing substrate 62, a first transverse sealing cylinder 63 and a second transverse sealing cylinder 64. The first transverse sealing cylinder 63 and the second transverse sealing cylinder 64 are relatively arranged below the longitudinal sealing mechanism 5, and the extension directions of the first transverse sealing cylinder 63 and the second transverse sealing cylinder 64 are opposite to each other. Exemplarily, the first transverse sealing cylinder 63 and the second transverse sealing cylinder 64 are fixed to the frame 1 through a mounting ring, and the extension direction of the first transverse sealing cylinder 63 is toward the second transverse sealing cylinder 64, and the extension direction of the second transverse sealing cylinder 64 is toward the first transverse sealing cylinder 63.

[0045] The first horizontal sealing substrate 61 and the second horizontal sealing substrate 62 are arranged between the first horizontal sealing cylinder 63 and the second horizontal sealing cylinder 64, and the first horizontal sealing substrate 61 is connected to the first horizontal sealing cylinder 63, and the second horizontal sealing substrate 62 is connected to the second horizontal sealing cylinder 64. More specifically, a copper layer 611 is arranged on the first horizontal sealing substrate 61, and the copper layer 611 faces the second horizontal sealing substrate 62 and is connected to the horizontal sealing hot air device. An aluminum layer 621 and a silicone layer 622 are arranged on the second horizontal sealing substrate 62, and the silicone layer 622 is arranged on the surface of the aluminum layer 621. When the bag is transversely sealed 101, the bag is located between the first transverse sealing substrate 61 and the second transverse sealing substrate 62, and the first transverse sealing cylinder 63 extends to drive the first transverse sealing substrate 61 to move toward the second transverse sealing substrate 62. At the same time, the second transverse sealing cylinder 64 extends to drive the second transverse sealing substrate 62 to move toward the first transverse sealing substrate 61 until the first transverse sealing substrate 61 and the second transverse sealing substrate 62 abut against each other to press the bag.

[0046] Furthermore, in order to increase the sealing performance of the bag and facilitate the user to tear the bag, a plurality of sealing stripes 612 are provided on the copper layer 611, and the plurality of sealing stripes 612 are arranged in sequence from top to bottom, and are in an I-shaped shape as a whole. Exemplarily, the sealing stripes 612 include a first horizontal portion, a second horizontal portion, and a vertical portion; the first horizontal portion and the second horizontal portion are arranged in sequence from top to bottom on the copper layer 611, and the sealing stripes 612 on the first horizontal portion are parallel to the horizontal plane, the second horizontal portion is in an arc shape as a whole, and the vertical portion is arranged between the first horizontal portion and the second horizontal portion, and is in the same straight line as the vertical seal 102. In order to facilitate the user to tear the left and right bags at the same time, a laser machine is also provided at the horizontal sealing mechanism 6, and the laser machine is arranged opposite to the vertical portion. Through the laser machine, a tear 105 can be formed on the vertical portion.

[0047] The punching mechanism 7 is arranged below the transverse sealing mechanism 6, and is used for cutting the sealed bag body. Specifically, the punching mechanism 7 includes a punching substrate 71, a punching cylinder 72, a cutter and a tight edge positioning portion 73, wherein the punching substrate 71 is arranged on the frame 1; the punching cylinder 72 is arranged below the transverse sealing mechanism 6, and the pushing direction of the punching cylinder 72 is toward the punching substrate 71; the cutter is connected to the punching cylinder 72. Exemplarily, the punching mechanism 7 includes a punch 711 and a die 712; an opening is provided on the die 712, and the opening is directly opposite to the punch 711; the punch 711 is in a stepped shape as a whole, and the step is set to be arc-shaped. When cutting the bag, the punching cylinder 72 extends to drive the cutter to move toward the punching substrate 71. After the cutter contacts the bag body, it will continue to move the bag body toward the punch 711 until the bag body contacts the punch 711. Then the cutter continues to move toward the die 712 and reaches the opening, thereby completing the cutting of the bag body. It should be noted that when cutting the bag body, the first transverse portion is divided into two parts, one of which serves as the bottom end of the bag body and the other as the head end of the bag body, so that the transverse seal 101 only needs to be performed once.

[0048] Furthermore, in order to facilitate bag cutting, the punching mechanism 7 also includes a tight edge positioning portion 73, which is arranged above the punching substrate 71, and the tight edge positioning portion 73 is a trapezoidal body that is wide at the top and narrow at the bottom, and is used to clamp the bag body. Exemplarily, the tight edge positioning portion 73 is in the shape of a square hopper, with a feed port and a discharge port. The bag body enters from the feed port and exits from the discharge port. In order to facilitate clamping the bag body, the discharge port is adapted to the shape of the bag body and can abut against the bag body. When cutting the bag, the punch 711 provides support force to the bag body, the tight edge positioning portion 73 clamps the upper part of the bag body, and the drawstring mechanism tightens the lower part of the bag body, so that the bag body can be in a flattened and tight state, which is convenient for the cutter to cut the bag. It should be noted that the drawstring mechanism is a prior art and will not be described here.

[0049] In order to facilitate the conveying of the cut bags, the double-bag fully automatic filling, sealing and forming integrated machine also includes a feeding conveyor belt 9, which is arranged below the punching mechanism 7, so that the cut bags fall onto the feeding conveyor belt 9 under the action of gravity, and are then conveyed to the next process through the feeding conveyor belt 9.

[0050] In order to improve the shelf life of the materials, the double-bag fully automatic filling, sealing and molding integrated machine also includes a nitrogen filling tube 8 fixed on the mounting frame 41, one end of the nitrogen filling tube 8 is connected to the nitrogen filling equipment, and the other end is inserted into the first molding tube 43 and the second molding tube 44, so that the nitrogen can reach the left bag body and the right bag body.

[0051] Working principle description:

[0052] The film supply mechanism 3 stretches the rolled film into a flat film, and transfers the film to the second group of rollers 33 through the first group of rollers 32, so that the film is parallel to the horizontal plane. At this time, the laser coding machine 35 located below the film codes, and then transfers the film to the third group of rollers 34. The color mark sensor 36 detects and locates the position of the film, and transfers the film to between the bag former 42 and the first forming tube 43 and the second forming tube 44 of the bag forming mechanism 4 through the third group of rollers 34, and preliminarily forms a bag body through the cooperation of the first guide block, the second guide block, the first forming tube 43 and the second forming tube 44.

[0053] Then, under the operation of the film pulling mechanism, it moves downward to the groove of the longitudinal sealing mechanism 5, the sealing plate 52 presses the bag body, and the longitudinal sealing cylinder 54 extends to drive the heated longitudinal heat sealer 53 to move toward the longitudinal sealing substrate 51 until it abuts against the longitudinal sealing substrate 51, completing the longitudinal sealing of the bag body.

[0054] Then, under the operation of the film pulling mechanism, it continues to move downward to between the first horizontal sealing substrate 61 and the second horizontal sealing substrate 62 of the horizontal sealing mechanism 6, and then the first horizontal sealing cylinder 63 and the second horizontal sealing cylinder 64 are started at the same time, driving the first horizontal sealing substrate 61 and the second horizontal sealing substrate 62 to move toward each other until the first horizontal sealing substrate 61 and the second horizontal sealing substrate 62 abut against each other, thereby completing the horizontal sealing of the bag body.

[0055] Then, under the operation of the film-pulling mechanism, it continues to move downward and passes through the tight edge positioning portion 73. Then, the punching cylinder 72 extends to drive the cutter to move toward the bag body until the bag body abuts against the punch 711. The cutter continues to move toward the die 712, so that the cutter can cut the bag body along the shape of the punch 711, thereby completing the bag cutting of the bag body; and then the fallen bag body is transported to the next process through the unloading conveyor belt 9.

[0056] It should be noted that the filling of materials is completed after the longitudinal sealing operation and before the transverse sealing operation.

[0057] In the first embodiment of the present invention, the double-linked bag fully automatic filling, sealing and forming integrated machine provided by the present application includes a feeding mechanism, a film supply mechanism, a bag forming mechanism, a longitudinal sealing mechanism, a transverse sealing mechanism and a punching mechanism; by staggering the first group of rollers, the conveying direction of the film can be in the vertical direction, effectively reducing the horizontal space occupied by the film supply mechanism; by horizontally arranging the second group of rollers above the laser coding machine, the coding quality is effectively improved, and the subsequent detection and forming operations are smoother; by arranging a one-way bearing, the problem of high-speed film rotation is effectively prevented. By arranging the longitudinal heat sealer between the first forming tube and the second forming tube, a bag body can have two unconnected accommodating cavities, which is convenient for packaging products that need to be used together. By arranging sealing stripes on the copper layer, the sealing of the bag body can be strengthened and the friction force can be increased; by arranging a silicone layer on the aluminum layer, the necessary pressure can be given during transverse sealing, so that the bag body is sealed without bubbles, thereby further improving the sealing performance. Compared with the existing all-in-one machines, the double-bag fully automatic filling, sealing and forming all-in-one machine provided in the present application can adapt to the requirements of high-speed film feeding, effectively prevent film rotation, and realize double-bag packaging through three-side sealing with good sealing quality. It completes fully automated production from film feeding to cutting, and has a simple and compact structure.

[0060] Based on the structure of the above-mentioned embodiment 1, the double-linked packaging bag 10 provided in this application is made based on the above-mentioned double-linked bag fully automatic filling, sealing and forming integrated machine. Figure 7 As shown, the double packaging bag 10 includes a horizontal seal 101, a vertical seal 102, a left chamber 103 and a right chamber 104. The left chamber 103 and the right chamber 104 are symmetrically arranged on both sides of the vertical seal 102 and are not connected to each other. They are used to store materials, and the materials can be the same or different. The horizontal seal 101 is respectively arranged at the upper and lower ends of the left chamber 103 and the right chamber 104, and the horizontal seal 101 is provided with sealing stripes. In order to prevent the double packaging bag 10 from scratching the user, the horizontal seal 101 is provided with rounded corners. Furthermore, in order to facilitate the user to tear open the left chamber 103 and the right chamber 104 at the same time, the double packaging bag 10 is also provided with a tear 105 and a fold 106. The fold 106 is arranged between the left chamber 103 and the right chamber 104 and overlaps with the center line of the vertical seal 102. The tear 105 is arranged on the horizontal seal 101 and is perpendicular to and crosses the fold 106.

[0061] In the embodiment of the present application, the double packaging bag provided by the present application, when the materials are divided into the left chamber and the right chamber, when the user uses it, he only needs to fold the left chamber and the right chamber along the crease first, and then tear the tear, and the left chamber and the right chamber can be torn open at the same time, which is convenient for subsequent use. By setting a tear, the number of times the user tears the tear can be effectively reduced, which is convenient for the user to use. Through vertical sealing and horizontal sealing, a bag body can achieve the effect of two materials being divided into three sides through three-side sealing, which is particularly suitable for materials that need to be stored separately but must be used together. It is convenient to use and has strong practicality.
