Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, and in particular to a filling device capable of continuously mixing and bagging products. Background Technology

[0002] Packaging machines are widely used in industries such as food, daily chemicals, pharmaceuticals, and electronics. They are suitable for packaging various items, including not only liquids but also powders, such as bagged powders and other powders.

[0003] When combining different materials for packaging, the heat-sealing process is crucial. Existing technologies typically employ two methods: 1. Intermittent heat sealing along the film's length conveying direction. First, a base heat-sealing line is formed on the film. Then, the first material is filled in, and a second heat-sealing line is applied intermittently. These two heat-sealing lines create independent chambers in the packaging film. This process is then repeated intermittently along the film's conveying direction, with the second material being filled in. The two separate bags containing different materials are then cut together for sale as a package. This method allows for continuous packaging production, but the packaging bag structure is essentially two connected, independent small packages, resulting in a limited product structure and a restricted market.

[0004] First, the packaging film is made into bags. The chamber distribution is pre-planned on the film material, and a heat-sealing device forms heat-sealing lines between the chambers and a bottom heat-sealing line, leaving an opening to form a semi-finished packaging bag. This is then transferred to a filling machine where each chamber is filled with material. Finally, the opening is heat-sealed to obtain a complete mixed-package bag. This production method allows for effective planning of the chamber distribution, creating multi-chamber single-bag packaging bags, enabling diversified designs for the market and giving it market competitiveness. However, the bag-making and filling process involves many steps, resulting in low production efficiency and high costs.

[0005] Therefore, if the process equipment can be improved to form a continuous production single-bag multi-chamber bag that can simultaneously mix and fill different liquid and solid materials into packaging bags, it will significantly improve production efficiency and market competitiveness. Summary of the Invention

[0006] In order to overcome the shortcomings of the above-mentioned technology, the present invention provides a filling device that can continuously mix and bag the contents.

[0007] The technical solution of the present invention: a filling equipment for continuous mixing and bagging, the filling equipment including a filling device, a packaging film conveying device, and a heat sealing device, wherein the packaging film conveying device drives the packaging film into the heat sealing device; The heat sealing device includes a pair of first heat sealing mechanisms mirror-arranged on both sides of the packaging film in the width direction. Each pair of first heat sealing mechanisms includes a guide seat, a sealing roller, and an electric heating coil. The two guide seats of the pair of first heat sealing mechanisms are arranged in a bucket-shaped structure around the packaging film. Each guide seat includes a bucket opening that is relatively far away from the packaging film and a bucket bottom that is close to the packaging film. The bucket opening is arranged facing the packaging film conveying direction. The bucket opening of the two guide seats contacts the edge of the packaging film in the width direction and gradually contacts and guides the packaging film to bend from a flat posture to a "U" shape as the packaging film moves forward. The filling device includes at least two discharge pipes, which are inserted into the "U"-shaped packaging film from one side of the hopper opening and pass through the bottom of the hopper. The at least two discharge pipes are spaced apart from the U-shaped opening to the bottom of the "U"-shaped packaging film, and the gap between the at least two discharge pipes is the chamber partition gap. The sealing roller is rotatably disposed at the bottom of the hopper. The sealing roller includes a rotating shaft, a sealing wheel that contacts the U-shaped opening of the "U"-shaped packaging film, and a sealing wheel that contacts the cavity partition gap. The sealing roller is made of thermally conductive material. The electric heating coil is fixed to the bottom of the hopper and engages with the rotating shaft of the sealing roller for thermal contact, heating the sealing roller and the sealing spacer roller. The sealing roller and sealing spacer roller of the pair of first heat sealing mechanisms are clamped to the outer side of the packaging film by heat pressing from both sides and make continuous rolling contact with the outer side of the packaging film that is being conveyed forward, forming sealing and sealing edges on the packaging film, and forming at least two chambers corresponding to the number of discharge pipes and the cross-sectional profile. The heat sealing device also includes a second heat sealing mechanism on one side of the bottom of the receiving hopper. The second heat sealing mechanism is activated and stopped alternately in conjunction with the filling device to form heat sealing strips and heat sealing bottom strips spaced along the conveying direction on the packaging film. The heat sealing strips and heat sealing bottom strips close the openings on both sides of the chamber.

[0008] The above technical solution is adopted, as shown in the appendix to the instruction manual. Figure 1-3 As shown, the packaging film conveying device drives the packaging film into the first heat-sealing mechanism. Through the structural design of the guide seat, after the packaging film enters the hopper, it gradually bends into a U-shaped structure, as shown... Figure 8 As shown in the cross-section; At this point, at least two discharge pipes are inserted into the "U"-shaped packaging film from one side of the hopper opening and pass through the bottom of the hopper, such as... Figure 9 , Figure 10 As shown; The sealing rollers, which rotate at the bottom of the hopper, further constrain the "U"-shaped posture towards the discharge pipe side, such as... Figure 7As shown, the packaging film transforms from a U-shape to a "gourd-shaped" shape that adheres to the outer wall of the discharge tube. (The "gourd-shaped" shape is only an adaptation display of the two discharge tubes in Embodiment 1 of this application. Under the principle of this application, when multiple chambers need to be set and the number of discharge tubes is increased, the outline of the packaging film changes accordingly, and the adhesion changes to a "candied hawthorn string" type adaptation display. Similarly, when the cross-sectional shape of the discharge tube changes, such as from a circle to a polygon or an irregular shape, the cross-sectional shape of the chamber of the packaging bag of this application changes accordingly. Therefore, the above description of "gourd-shaped" and the like is a preferred image display for explaining the principle and is not limited to the above shape.)

[0009] The at least two discharge pipes are spaced apart from each other in the direction from the U-shaped opening to the U-shaped bottom of the packaging film, and the gap between the at least two discharge pipes is the chamber partition gap, such as... Figure 6 As shown; like Figures 8 to 10 The continuous demonstration of the first heat sealing mechanism enables the outer side of the packaging film to be clamped by heat pressure from both sides and to make continuous rolling contact with the outer side of the packaging film that is being conveyed forward, forming sealing rolls and sealing rolls on the packaging film, and forming at least two chambers corresponding to the number of discharge pipes and the cross-sectional profile. A further feature of the present invention is that the sealing roller is provided with at least two embossing roller portions on the outer side of the packaging film corresponding to each chamber, and the outer peripheral surface of the embossing roller portions is provided with hot-pressed knurling of text or pattern outlines. On the outer circumferential surface of the at least two discharge pipes, a heat insulation pad is provided corresponding to the position of each indentation wheel. The indentation wheel rolls under heat pressure on the heat insulation pad to form a LOGO area with text or pattern outline on the packaging film.

[0010] The above technical solution is adopted, as described in the instruction manual. Figure 6 , Figure 11 , Figure 12 As shown, the embossing rollers are heated and rolled over the heat-insulating layer to form the logo area with text or graphic outlines on the packaging film. The heat-insulating layer (such as existing materials like heat-insulating cloth) is designed to prevent heat from the embossing rollers from being transferred to the discharge pipe, thus avoiding affecting the material. The discharge pipe extends a certain distance from the bottom of the hopper, and the material is filled after the packaging film has been formed in the cavity.

[0011] A further feature of the present invention is that the outer peripheral surface of the indentation roller is provided with a notch to break the text or pattern, which makes the LOGO area appear at intervals.

[0012] A further feature of the present invention is that the electric heating coil component includes a shaft assembly, a heating coil, and a housing component. The shaft assembly is made of a thermally conductive material and has a central hole that engages with the rotating shaft and a flange portion for fixing the position. The heating coil is sleeved on the outer circumferential surface of the shaft assembly, and the housing component covers and fixes the shaft assembly and the heating coil.

[0013] The above technical solutions, as shown in the attached manual, are as follows. Figure 4 , 11 As shown in Figures 1 and 12, the electric heating coil structure heats the edge sealing roller through the rotational contact of the shaft assembly and the rotating shaft.

[0014] The principle of heat sealing is to use external conditions to heat the sealing area of ​​the plastic film, turning it into a viscous state, and then, with the help of a certain external force, to fuse the two layers of film together, maintaining a certain strength after cooling. Heat sealing using electric heating has the advantages of fast heating speed and a large heating range, reaching up to 300°C.

[0015] A further feature of the present invention is that the packaging film conveying device is provided with a film cutting mechanism, which cuts the packaging film into several strips of equal width along the conveying direction; The heat sealing device is configured with several pairs of first heat sealing mechanisms corresponding to the positions and quantities of several strip packaging films; The filling device corresponds to the position and quantity of several strip packaging films and is equipped with at least two discharge pipes arranged in several groups.

[0016] The above technical solution is adopted, as shown in the appendix to the instruction manual. Figure 1-2 As shown, large pieces of packaging film are cut according to working conditions, and heat sealing and filling devices are designed to form a multi-station packaging bag forming, filling and heat sealing process, which significantly improves production efficiency.

[0017] A further feature of the present invention is that the second heat-sealing mechanism includes a plurality of movable heat-sealing heads and a plurality of fixed heat-sealing heads arranged along the direction from the U-shaped opening to the bottom of the U-shape. The plurality of movable heat-sealing heads and the plurality of fixed heat-sealing heads are arranged in pairs on both sides of each strip of packaging film and are opposite to each other. The second heat sealing mechanism includes a cylinder, a stationary base for fixing several fixed heat sealing heads, and a movable base for fixing several movable heat sealing heads. The piston rod of the cylinder works in conjunction with the movable base to drive the several movable heat sealing heads to reciprocate opening and closing relative to the several fixed heat sealing heads, forming a heat sealing strip and a heat sealing bottom strip.

[0018] The above technical solution is adopted, as shown in the appendix to the instruction manual. Figure 1 , 2 As shown in Figure 13, the structural design of the second heat-sealing mechanism, through an alternating motion structure, achieves heat sealing of the packaging film along the U-shaped opening to the U-shaped bottom direction, making the heat sealing strip and the heat sealing bottom strip adapt to the overall direction of the packaging bag, thus avoiding wrinkles in the packaging bag.

[0019] A further feature of the present invention is that the device also includes a PLC controller that is signal-controlled with the filling device and the cylinder. The filling device works in conjunction with the reciprocating motion of the cylinder to alternately fill the chamber with material.

[0020] The beneficial effects of this invention lie in the interconnected design of the filling device, packaging film conveying device, and heat sealing device. This design enables the packaging film to form a multi-chamber heat-sealed structure within a single bag, and to complete bag formation, bottom sealing, filling, and sealing on a single production line. Compared to the two existing processes, this invention offers advantages such as controllable chamber number and outline, no need for bag transfer equipment, and high production efficiency. Furthermore, the discharge pipe serves multiple functions, including filling, core molding, and logo heat-pressing support, resulting in highly integrated and compact equipment.

Furthermore, the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. Detailed Implementation

[0023] To make the technical solution and advantages of this application clearer, the technical solution of this application will be described in a clearer and more complete manner below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this application, and are only used to explain this application, not to limit this application. It should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings. Other related parts can be referred to the general design. In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other to obtain new embodiments.

[0024] The invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-13 As shown; A continuous mixing and bagging filling equipment, the filling equipment includes a filling device 1, a packaging film conveying device 2, and a heat sealing device, wherein the packaging film conveying device 2 drives the packaging film 21 into the heat sealing device; The heat sealing device includes a pair of first heat sealing mechanisms 3 mirror-arranged on both sides of the packaging film 21 in the width direction. Each pair of first heat sealing mechanisms 3 includes a guide seat 31, an edge sealing roller 32, and an electric heating coil 33. The two guide seats 31 of the pair of first heat sealing mechanisms 3 surround the packaging film 21 in a bucket-shaped structure. Each guide seat 31 includes a bucket opening 311 relatively far away from the packaging film 21 and a bucket bottom 312 close to the packaging film 21. The bucket opening 311 is arranged facing the conveying direction of the packaging film 21. The bucket opening 311 of the two guide seats 31 contacts the edge of the packaging film 21 in the width direction and gradually contacts and guides the packaging film 21 to bend from a flat posture to a "U" shaped posture as the packaging film 21 moves forward. The filling device 1 includes at least two discharge pipes 11. The at least two discharge pipes 11 are inserted into the "U"-shaped packaging film 21 from one side of the hopper opening 311 and pass through the bottom 312 of the hopper. The at least two discharge pipes 11 are spaced apart from the U-shaped opening to the U-shaped bottom of the "U"-shaped packaging film 21. The gap between the at least two discharge pipes 11 is the chamber partition gap 12. The sealing roller 32 is rotatably disposed at the bottom of the hopper 312. The sealing roller 32 includes a rotating shaft 321, a sealing wheel 322 that contacts the U-shaped opening of the "U"-shaped packaging film 21, and a sealing wheel 323 that contacts the cavity partition gap 12. The sealing roller 32 is made of a heat-conducting material. The electric heating coil 33 is fixed to the bottom 312 of the hopper and engages with the rotating shaft 321 of the sealing roller 32 for heat conduction, heating the sealing roller 322 and the sealing roller 323. The sealing roller 322 and the sealing roller 323 of the pair of first heat sealing mechanisms 3 are clamped to the outer side of the packaging film 21 by heat pressing from both sides, and make continuous rolling contact with the outer side of the packaging film 21 that is being conveyed forward, forming sealing roller 211 and sealing roller 212 on the packaging film 21, and forming at least two chambers 213 corresponding to the number and cross-sectional profile of the discharge pipe 11. The heat sealing device also includes a second heat sealing mechanism 4 on one side of the bottom 312 of the receiving hopper. The second heat sealing mechanism 4 is switched on and off alternately with the filling device 1 by signal control, forming heat sealing strips and heat sealing bottom strips spaced along the conveying direction on the packaging film 21. The heat sealing strips and heat sealing bottom strips close the openings on both sides of the chamber 213.

[0025] As per the instruction manual Figure 1-3 As shown, the packaging film conveying device 2 drives the packaging film 21 into the first heat sealing mechanism 3. Through the structural design of the guide seat 31, after the packaging film 21 enters the hopper 311, it gradually bends into a U-shaped structure, as shown. Figure 8 As shown in the cross-section; At this time, at least two discharge pipes 11 are inserted into the "U"-shaped packaging film 21 from one side of the hopper opening 311 and pass through the bottom 312 of the hopper, as shown. Figure 9 , Figure 10 As shown; The sealing rollers 32, which are rotatably mounted at the bottom 312 of the hopper, further constrain the "U"-shaped posture towards the discharge pipe 11, such as... Figure 7As shown, the packaging film 21 transforms from a U-shape to a "gourd shape" that adheres to the outer wall of the discharge tube 11. (The "gourd shape" is only an adaptation display for the two discharge tubes 11 in Embodiment 1 of this application. Under the principle of this application, when multiple chambers 213 need to be set and the number of discharge tubes 11 is increased, the outline of the packaging film 21 changes accordingly, and the adhesion changes to a "candied hawthorn string" type adaptation display. Similarly, when the cross-sectional shape of the discharge tube 11 changes, such as from a circle to a polygon or an irregular shape, the cross-sectional shape of the chamber 213 of the packaging bag of this application changes accordingly. Therefore, the above description of "gourd shape" etc. is a preferred image display for explaining the principle and is not limited to the above shape.)

[0026] The at least two discharge pipes 11 are spaced apart from each other in the direction from the U-shaped opening to the U-shaped bottom of the "U"-shaped packaging film 21, and the gap between the at least two discharge pipes 11 is the chamber partition gap 12. Figure 6 As shown; like Figures 8 to 10 The continuous demonstration of the first heat sealing mechanism 3 enables the outer side of the packaging film 21 to be clamped by heat pressure from both sides, and to make continuous rolling contact with the outer side of the packaging film 21 that is being conveyed forward, forming sealing roller 211 and sealing roller 212 on the packaging film 21, and forming at least two chambers 213 corresponding to the number and cross-sectional profile of the discharge pipe 11. The sealing roller 32 is provided with at least two embossing roller portions 324 on the outer side of the packaging film 21 where each chamber 213 is located. The outer peripheral surface of the embossing roller portion 324 is provided with hot knurling 3241 of text or pattern outline. On the outer circumferential surface of the at least two discharge pipes 11, a heat insulation pad 111 is provided corresponding to the position of each indentation wheel 324. The indentation wheel 324 is hot-pressed and rolled on the heat insulation pad 111 to form a LOGO area with text or pattern outline on the packaging film 21.

[0027] As per the instruction manual Figure 6 , Figure 11 , Figure 12 As shown, the embossing roller 324 is hot-pressed onto the heat insulation pad 111, forming a logo area with text or pattern outlines on the packaging film 21. The heat insulation pad 111 (such as existing materials like heat insulation cloth) is designed to prevent heat from the embossing roller 324 from being transferred to the discharge pipe 11, thus avoiding affecting the material. The discharge pipe 11 extends a certain distance from the bottom 312 of the hopper and is filled with material after the packaging film 21 has formed in the chamber 213.

[0028] The outer circumferential surface of the indentation roller has a notch that breaks the text or pattern, which makes the LOGO area appear in intervals.

[0029] The electric heating coil component 33 includes a shaft assembly 331, a heating coil 332, and a housing component 333. The shaft assembly 331 is made of a thermally conductive material and has a central hole that engages with the rotating shaft 321 and a flange portion for fixing the position. The heating coil 332 is fitted onto the outer circumferential surface of the shaft assembly 331, and the housing component 333 covers and assembles and fixes the shaft assembly 331 and the heating coil 332.

[0030] As per the instruction manual Figure 4 , 11 As shown in Figures 1 and 12, the electric heating coil 33 structure heats the edge sealing roller 32 through the rotational contact of the shaft assembly 331 and the rotating shaft 321.

[0031] The principle of heat sealing is to use external conditions to heat the sealing area of ​​the plastic film, turning it into a viscous state, and then, with the help of a certain external force, to fuse the two layers of film together, maintaining a certain strength after cooling. Heat sealing using electric heating has the advantages of fast heating speed and a large heating range, reaching up to 300°C.

[0032] The packaging film conveying device 2 described herein is provided with a film cutting mechanism, which cuts the packaging film 21 into several strips of equal width along the conveying direction; The heat sealing device corresponds to the position and quantity of several strip packaging films 21, and is equipped with several pairs of first heat sealing mechanisms 3; The filling device 1 corresponds to the position and quantity of several strip packaging films 21, and is equipped with at least two discharge pipes 11 arranged in several groups.

[0033] As per the instruction manual Figure 1-2 As shown, the large packaging film 21 is cut according to the working conditions, and a heat sealing device and a filling device 1 are designed to form a multi-station packaging bag forming, filling and heat sealing process, which significantly improves production efficiency.

[0034] The second heat sealing mechanism 4 includes a plurality of movable heat sealing heads 41 and a plurality of fixed heat sealing heads 42 arranged along the direction from the U-shaped opening to the bottom of the U-shaped opening. The plurality of movable heat sealing heads 41 and the plurality of fixed heat sealing heads 42 are arranged in pairs on both sides of each strip packaging film 21 and are opposite to each other. The second heat sealing mechanism 4 includes a cylinder 43, a stationary base 421 that fixes several fixed heat sealing heads 42, and a movable base 411 that fixes several movable heat sealing heads 41. The piston rod of the cylinder 43 is linked with the movable base 411 to drive the several movable heat sealing heads 41 to reciprocate opening and closing relative to the several fixed heat sealing heads 42, forming a heat sealing strip and a heat sealing bottom strip.

[0035] As per the instruction manual Figure 1 , 2As shown in Figure 13, the structural design of the second heat-sealing mechanism 4, through an alternating motion structure, enables the heat-sealing strip and heat-sealing bottom strip of the packaging film 21 to be aligned with the overall direction of the packaging bag, thereby avoiding wrinkles in the packaging bag.

[0036] The equipment also includes a PLC controller that is signal-controlled with the filling device and the cylinder 43. The filling device works in conjunction with the reciprocating motion of the cylinder 43 to alternately fill the chamber 213 with material.

[0037] The beneficial effects of this invention are that, through the structural linkage design of the filling device 1, the packaging film conveying device 2, and the heat sealing device, the packaging film 21 forms a heat-sealed structure of a single bag with multiple chambers 213, and the bags are formed, sealed at the bottom, filled, and sealed on a single production line. Compared with the two existing processes, this invention has the advantages of controllable number and outline of chambers 213, no need to transfer the bag body, and high production efficiency. At the same time, the discharge pipe 11 has the combined functions of filling, core mold, and logo heat-press support, thus making the equipment highly integrated and compact in structure.

[0038] The technical solution of this application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
