Description

Technical Field

[0002] Packaging machines are machines that package products for protection and aesthetics. They are categorized by machine type, including liquid packaging machines, powder packaging machines, granule packaging machines, skin packaging machines, sauce packaging machines, and pillow packaging machines. Back-seal powder packaging machines are commonly used in the production and processing of powders. These machines seal both ends and the back of the bag. Currently, powder packaging machines are widely used for quantitative packaging of powdered materials in the chemical, pharmaceutical, food, and agricultural products industries.

[0003] The packaging process of existing back-seal powder packaging machines generally includes film supply, vertical sealing, horizontal sealing, unloading and cutting processes. With the development of cost reduction and efficiency improvement, multi-row back-seal powder packaging machines are becoming more and more popular. However, since the unloading, film supply, vertical sealing, horizontal sealing and cutting of multiple stations are all controlled separately and need to cooperate with each other, the control of existing multi-row back-seal powder packaging machines is not precise enough and the coordination is not smooth enough, which easily leads to material waste and greatly affects the packaging efficiency. At the same time, when the roll film is used up, the existing film replacement operation is generally: a roll of new film is placed on the film rack, and then one end of the roll film is fixed on the film clamp, and then the roll film is pulled out of the film clamp at one end length and passed through the film guide device to realize the operation of the film. However, this process is not only complicated to operate and inefficient, but also prone to problems such as uneven film and crooked film.

[0004] Therefore, it is urgent to design a multi-row back-sealed powder packaging machine that can improve the accuracy and smoothness of the coordination between operations such as feeding, film feeding, vertical sealing, horizontal sealing and cutting, achieve efficient production, and reduce material waste. At the same time, the multi-row back-sealed powder packaging machine can achieve rapid film connection, greatly simplify the film changing operation, improve the film changing efficiency, and the film connection is smooth, which effectively solves the problem of uneven or crooked film during the existing film changing, and further improves the packaging quality of the product.

[0037] In response to the above problems, an embodiment of the present application provides a multi-column back-sealed powder packaging machine that can accurately control operations such as material unloading, film supply, vertical sealing, horizontal sealing and cutting, so that they work together smoothly, achieve efficient production and reduce material waste.

[0038] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0039] Example 1

[0040] See also Figures 1-10The multi-row back-seal powder packaging machine provided in this application includes a cabinet 1, a film feeding mechanism 2, a material feeding mechanism 3, a collar forming mechanism 4, a longitudinal sealing mechanism 5, a transverse sealing mechanism 6, a punching mechanism 7, and several servo motors 8. The material feeding mechanism 3 is disposed above the cabinet 1, and the film feeding mechanism 2, the collar forming mechanism 4, the longitudinal sealing mechanism 5, the transverse sealing mechanism 6, and the punching mechanism 7 are all disposed within the cabinet 1.

[0041] Specifically, such as Figure 1-Figure 2 As shown, the cabinet 1 includes a frame and a cabinet door 11. In order to improve the structural strength of the entire cabinet 1, the frame and the cabinet door 11 are made of stainless steel or aluminum alloy. In order to facilitate observation of the internal situation, the cabinet door 11 can also be made of transparent materials, such as transparent glass or transparent plastic, etc., which is not limited here.

[0042] like Figure 3 As shown, the feeding mechanism 3 includes a silo 31 and N discharge ports 32. The servo motor 8 is connected to the silo 31, and the silo 31 is fixed to the cabinet 1 via a support rod. The N discharge ports 32 are sequentially arranged at the lower end of the silo 31 and are in communication with the silo 31, wherein N is a natural number greater than or equal to 1. For example, N is 12, that is, the discharge ports 32 are set to 12, so that simultaneous and rapid discharge can be achieved, thereby improving efficiency.

[0043] The film feeding mechanism 2 is arranged on one side of the cabinet 1, and is used to stretch and flatten the roll film into a packaging film, and transmit the packaging film to the lapel forming mechanism 4; the lapel forming mechanism 4, the longitudinal sealing mechanism 5, the transverse sealing mechanism 6 and the punching mechanism 7 are arranged on one side of the film feeding mechanism 2 in sequence from top to bottom; several servo motors 8 are respectively connected to the feeding mechanism 3, the film feeding mechanism 2, the longitudinal sealing mechanism 5, the transverse sealing mechanism 6 and the punching mechanism 7.

[0044] Specifically, the lapel forming mechanism 4 is disposed on one side of the film supply mechanism 2 and is used to shape the packaging film into a bag-shaped structure. The longitudinal sealing mechanism 5 is disposed below the lapel forming mechanism 4 and is used to seal the back of the bag-shaped structure under the drive of the servo motor 8. The transverse sealing mechanism 6 is disposed below the longitudinal sealing mechanism 5 and is used to seal the upper and lower ends of the bag-shaped structure under the drive of the servo motor 8, thereby forming a sealed bag structure. The punching mechanism 7 is disposed below the transverse sealing mechanism 6 and is used to cut the sealed bag structure into separate packaging bags under the drive of the servo motor 8.

[0045] In the first embodiment of the present invention, the multi-column back-sealed powder packaging machine provided in the first embodiment of the present application includes a film supply mechanism, a feeding mechanism, a lapel forming mechanism, a longitudinal sealing mechanism, a transverse sealing mechanism, a punching mechanism, and a plurality of servo motors. By providing a plurality of servo motors, the actions of the film supply mechanism, the feeding mechanism, the longitudinal sealing mechanism, the transverse sealing mechanism, and the punching mechanism can be accurately controlled, thereby improving the precision and smoothness of the coordination between the various processes, thereby increasing the speed of film supply. At the same time, by providing N discharge ports, batch packaging can be carried out, which greatly improves the efficiency of powder packaging. Compared with the existing powder back-sealing machine, the solution provided by the present application can improve the precision and smoothness of the coordination between operations such as feeding, film supply, vertical sealing, transverse sealing, and cutting, thereby achieving efficient production and reducing material waste.

[0046] Example 2

[0047] In current powder back-sealing machines, when the film roll runs out, the conventional film replacement operation is generally as follows: a new film roll is placed on the film rack, one end of the film roll is fixed to the film clamp, and then the film roll is pulled out of the film clamp at one end and passed through the film guide device to realize the film operation. However, this process is not only complicated and inefficient, but also prone to problems such as uneven film and film distortion. In order to solve the above problems, this application proposes a corresponding solution, please refer to Figures 1-10 , specifically:

[0048] Based on the structure of the above embodiment 1, the film supply mechanism 2 includes a film supply frame 21, a film roll mounting shaft 22 and a film guide roller 23. The film supply frame 21 is connected to the cabinet 1. Specifically, Figure 4 As shown, the film supply rack 21 includes a first side panel 211 and a second side panel 212, which are arranged parallel and symmetrically on the cabinet 1. The film roll mounting shaft 22 is arranged on the film supply rack 21 for placing the film roll. Exemplarily, the first side panel 211 and the second side panel 212 are also provided with mounting grooves, and the ends of the film roll mounting shaft 22 are placed in the mounting grooves. The servo motor 8 is fixed to one side of the film supply rack 21, and the output end of the servo motor 8 is connected to the film roll mounting shaft 22. Exemplarily, the servo motor 8 is fixed to the first side panel 211 and is located outside the first side panel 211. Its output end passes through the first side panel 211 and is connected to the main gear. The main gear is meshed with the slave gear mounted on the film roll mounting shaft 22. When the servo motor 8 is started, it drives the main gear to rotate, which in turn drives the slave gear to rotate, and then drives the film roll mounting shaft 22 to rotate synchronously.

[0049] To facilitate film splicing and film transfer, the film guide rubber rollers 23 include a first rubber roller 231, a second rubber roller 232, and a third rubber roller 233. The first and second rubber rollers 231, 232 are arranged parallel to each other on the film supply frame 21 and below the film roll mounting shaft 22. The third rubber roller 233 is positioned between the film supply frame 21 and the collar forming mechanism 4. Specifically, the first rubber roller 231 is slightly higher than and located inside the second rubber roller 232. The third rubber roller 233 is higher than the film roll mounting shaft 22. After the film roll on the film roll mounting shaft 22 is stretched and flattened, it is passed from below the first rubber roller 231 to above the second rubber roller 232, then from below the second rubber roller 232 to the third rubber roller 233. The third rubber roller 233 then transfers the packaging film to the collar forming mechanism 4.

[0050] Furthermore, to make film splicing easier and the joint smoother, the film supply mechanism 2 also includes a film splicing plate 24 and a tape placement seat 25; the film splicing plate 24 is fixed to the film supply frame 21 and is located between the first rubber roller 231 and the second rubber roller 232, and is used to position and place the packaging film. The tape placement seat 25 is set on the film supply frame 21 and directly faces the positioning line 241. Specifically, the film splicing plate 24 is provided with a positioning line 241 and a notch 242; the positioning line 241 is set in the middle area of ​​the film splicing plate 24, and the notches 242 are symmetrically arranged on both sides of the positioning line 241 and are connected to the vacuum equipment. To improve the vacuuming effect, the notches 242 include crisscrossing strip grooves. The tape placement seat 25 is provided with a placement protrusion 251 and a blade 252. The placement protrusion 251 is used to place the film roll, and the blade 252 is arranged between the placement protrusion 251 and the first side plate 211 for cutting the tape. When the film needs to be replaced, the new film is placed on the film roll mounting shaft 22, then stretched into a thin packaging film, and the packaging film is passed around the first set of rubber rollers and placed on the film splicing plate 24, with the leading end of the packaging film flush with the positioning line 241. At the same time, the trailing end of the old film is also placed on the other side of the film splicing plate 24, flush with the positioning line 241. The vacuum device is turned on so that the new film and the old film can be evenly adsorbed on the film splicing plate 24. At this time, the leading end of the new film is flush with and in contact with the trailing end of the old film. The tape is pulled apart, sticking to the new and old films at the same time, and the tape is cut with the blade 252, thus completing the film splicing step.

[0051] Furthermore, in order to prevent the film roll position from being offset, the film supply mechanism 2 also includes a screw rod 26 and a photoelectric sensor. The photoelectric sensor is arranged on the cabinet 1 and is located on one side of the film roll mounting shaft 22, and is used to detect the position of the film roll. The two ends of the screw rod 26 are fixed on the cabinet 1, and the film supply rack 21 is sleeved on the screw rod 26, and a movable gap is provided between the screw rod 26 and the cabinet 1, that is, the length of the screw rod 26 is greater than the distance between the first side plate 211 and the second side plate 212. The output end of the servo motor 8 is connected to the screw rod 26 for driving the screw rod 26 to move. When the photoelectric sensor senses that the film roll position is offset, a signal is sent to the controller, and the controller instructs the servo motor 8 to start, driving the screw rod 26 to move, thereby driving the film supply rack 21 to move on the screw rod 26, and then adjusting the position of the film roll until the film roll reaches the preset position, and then turning off the servo motor 8.

[0052] In the embodiment of the present application, by setting the positional relationship between the first and second rubber rollers and the film roll mounting shaft, the packaging film can bypass the first rubber roller and reach the top of the film splicing plate, facilitating film splicing. The second rubber roller changes the direction of the packaging film so that the packaging film running on the third rubber roller faces downward with the marking, facilitating subsequent bag formation. Positioning lines are provided on the film splicing plate to facilitate alignment of the new and old films, making film splicing more uniform. Notches are provided on the film splicing plate that communicate with the vacuum device to absorb air between the film splicing plate and the packaging film, allowing the new and old films to be smoothly adsorbed on the film splicing plate, effectively improving film splicing efficiency and effectiveness.

[0053] Example 3

[0054] Based on the structures of the above-mentioned embodiment 1 and embodiment 2, the following technical solutions can be specifically adopted to realize the operations of forming, vertical sealing, horizontal sealing and cutting of the packaging bag. Figures 1-10 , specifically:

[0055] like Figure 5-Figure 6As shown, the lapel forming mechanism 4 includes N bag formers fixed on the cabinet 1, and the N bag formers are arranged in sequence below the discharge port 32. Any of the bag formers includes a curved turning leader plate 41 and a central material pipe 42. The curved turning leader plate 41 is arranged on one side of the third rubber roller 233. The central material pipe 42 is fixed at the intersection of the collar of the curved turning leader plate 41, and the top of the central material pipe 42 is connected to the discharge port 32. When the packaging film is transferred to the bag former via the third rubber roller 233, the packaging film will be positioned between the curved turning leader plate 41 and the central material pipe 42, and under the guidance of the curved turning leader plate 41, its two side edges will simultaneously move toward the middle to form a bag body. Furthermore, in order to prevent the powder from scattering into the environment, causing environmental pollution and damage to the machine, a vacuum cleaner 43 is also provided on one side of the bag former. It should be noted that when the third rubber roller 233 conveys the packaging film, it will pass through N-1 cutters arranged in parallel, and the cutters will cut a whole piece of packaging film into N pieces of packaging film to facilitate shaping by the N bag formers.

[0056] like Figure 6-Figure 7 As shown, the longitudinal sealing mechanism 5 includes N longitudinal sealing substrates 51, N blocks 52, longitudinal sealing mounting plates 53, N heat sealers 54 and a transmission assembly 55. The N longitudinal sealing substrates 51 are arranged side by side below the lapel forming mechanism 4. Specifically, the N longitudinal sealing substrates 51 are fixed on the cabinet 1 and are located directly below the bag maker. A circular groove is provided on the longitudinal sealing substrate 51, and the slot hole of the circular groove faces the heat sealer 54. The central material tube 42 is passed through the circular groove. When the bag body moves onto the longitudinal sealing substrate 51, the dorsal fin of the bag body extends from the slot hole. In order to facilitate the heat sealer 54 to seal the dorsal fin, the N blocks 52 are arranged at the upper ends of the N longitudinal sealing substrates 51 and cover the slot hole, so that when the dorsal fin extends from the slot hole, the dorsal fin is folded to one side under the resistance of the block 52.

[0057] The vertical sealing mounting plate 53 is arranged parallel to the N vertical sealing substrates 51, and the N heat sealers 54 are arranged side by side on the vertical sealing mounting plate 53, corresponding one to one with the vertical sealing substrates 51. The transmission assembly 55 is connected to the vertical sealing mounting plate 53 and is used to drive the vertical sealing mounting plate 53 and the heat sealers 54 toward the vertical sealing substrates 51. Specifically, the transmission assembly 55 includes a transmission shaft 551, a gear set 552, an eccentric wheel 553, and a telescopic guide rod 554. The transmission shaft 551 is connected to the servo motor 8 via the gear set 552. The eccentric wheel 553 is sleeved on the transmission shaft 551. The telescopic guide rod 554 is connected to the eccentric wheel 553, and the telescopic guide rod 554 extends and contracts perpendicular to the direction of the transmission shaft 551. Exemplarily, the transmission shaft 551 is arranged on the back side of the vertical sealing substrate 51, and the length direction of the transmission shaft 551 is parallel to the vertical sealing mounting plate 53, the gear set 552 is sleeved on the transmission shaft 551, the output end of the servo motor 8 is connected to the gear set 552, and the eccentric wheel 553 is arranged at both ends of the transmission shaft 551; one end of the telescopic guide rod 554 is fixedly connected to the eccentric wheel 553, and the other end is fixedly connected to the vertical sealing mounting plate 53. When longitudinal sealing is required, the servo motor 8 is started, driving the gear set 552 to rotate, thereby driving the transmission shaft 551 to rotate, and then driving the eccentric wheel 553 to rotate, and the eccentric wheel 553 converts the rotational movement of the transmission shaft 551 into a linear reciprocating motion of the telescopic guide rod 554, and the movement of the telescopic guide rod 554 drives the longitudinal sealing mounting plate 53 and N heat sealers 54 to move synchronously toward the direction of the longitudinal sealing substrate 51 until the heat sealer 54 abuts against the dorsal fin of the bag body and heat seals the dorsal fin.

[0058] like Figure 8-Figure 9As shown, the transverse sealing mechanism 6 includes a first transverse sealing plate 61, a second transverse sealing plate 62, a rotating shaft 63, a first cam 64, a second cam 65, a first connecting rod 66, and a second connecting rod 67. The servo motor 8 is connected to the rotating shaft 63 via a rotating gear. The first cam 64 and the second cam 65 are sequentially arranged at both ends of the rotating shaft 63. The first connecting rod 66 is arranged inside the first cam 64 and fixedly connected to it; the second connecting rod 67 is arranged outside the second cam 65 and fixedly connected to it. The first transverse sealing plate 61 is connected to the first connecting rod 66; the second transverse sealing plate 62 is connected to the second connecting rod 67, and the second transverse sealing plate 62 is provided with a heat sealer 54. When the servo motor 8 is started, it drives the rotating shaft 63 connected to it to rotate, and then drives the first cam 64 and the second cam 65 to rotate. By arranging the first connecting rod 66 on the inner side of the first cam 64 and the second connecting rod 67 on the outer side of the second cam 65, a positive and negative offset is formed, and then the first transverse sealing plate 61 is driven to move toward the second transverse sealing plate 62 through the first connecting rod 66. At the same time, the second transverse sealing plate 62 is driven to move toward the first transverse sealing plate 61 by the second connecting rod 67, so that the first transverse sealing plate 61 and the second transverse sealing plate 62 can move toward each other, thereby sealing the bag body.

[0059] To improve the sealing performance of the bag's heat seal, a silicone plate is also provided on the first transverse sealing plate 61. When the heat sealer 54 on the second transverse sealing plate 62 moves toward the first transverse sealing plate 61 and presses the bag onto the silicone plate, the silicone plate can provide the necessary pressure, allowing the bag to fit tightly and preventing bubbles from forming, thereby improving the quality of the heat seal. Furthermore, to improve the efficiency of disassembly and assembly of the silicone plate, the transverse sealing mechanism 6 also includes a clamping block 68, through which the silicone plate is fixed to the first transverse sealing plate 61. Fixing the silicone plate to the first transverse sealing plate 61 via the clamping block 68 effectively avoids the cumbersome disassembly and assembly of the silicone plate caused by existing screw fixation, and has a simple structure and high disassembly and assembly efficiency.

[0060] like Figure 10As shown, the punching mechanism 7 includes a transmission rod 71, a cutter mounting plate 72, a cutting die, and a cutter; the cutting die is fixed to the cabinet 1 and is located below the transverse sealing mechanism 6. The output end of the servo motor 8 is connected to the transmission rod 71, and the cutter mounting plate 72 is connected to the transmission rod 71. The cutter is installed on the cutter mounting plate 72. When the bag is delivered to the punching mechanism 7, the servo motor 8 is activated, driving the transmission rod 71 to rotate, thereby driving the cutter mounting plate 72 to move in the direction of film cutting, and simultaneously driving the cutter to move in the direction of film cutting, thereby cutting the bag into individual packaging bags.

[0061] It should be noted that, in order to facilitate the transmission of the packaging film to the lapel forming mechanism 4 and smoothly reach the longitudinal sealing mechanism 5 and the transverse sealing mechanism 6, the multi-row back-sealed powder packaging machine also includes a bag pulling mechanism 9, which is arranged below the transverse sealing mechanism 6 and above the punching mechanism 7. The structure of the bag pulling mechanism 9 adopts the existing technology and will not be repeated here.

[0062] The multi-column back-seal powder packaging machine provided by the present application is characterized by placing the film roll on the film roll mounting shaft, starting the servo motor to drive the film roll mounting shaft to rotate, and causing the packaging film to pass through the first rubber roller, the second rubber roller, and the third rubber roller in sequence, and then the packaging film is formed into a bag shape by the collar forming mechanism. The servo motor connected to the longitudinal sealing mounting plate is then started to drive the heat sealer to move toward the longitudinal sealing base plate to complete the back seal of the bag. At the same time, the feeding mechanism opens the discharge port so that the material can fall into the bag. The servo motor connected to the first and second transverse sealing plates is then started to drive the first and second transverse sealing plates to move toward each other, thereby completing the sealing of the upper and lower ends of the bag. The servo motor connected to the cutter mounting plate is then started to drive the cutter mounting plate and the cutter to move toward the film cutting, thereby completing the bag cutting action. Under the control of several servo motors, the film feeding mechanism, feeding mechanism, longitudinal sealing mechanism, transverse sealing mechanism, and punching mechanism can be precisely coordinated, further improving product quality and production efficiency.
