Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of quantitative packaging, and in particular, to a quantitative packaging mechanism for bagged multi-category materials. Background Art

[0002] In modern industrial production and daily life, the demand for packaging of multiple categories of materials is extensive and diverse. From food, medicine to chemical raw materials, from fine powder materials to larger particles, they all need to be accurately and efficiently packaged into bags to meet the requirements of market sales, product use, storage and transportation.

[0003] In the food field, multiple categories include solid food and liquid food, such as peanuts, pickled mustard tubers, and soups that need to be packaged together. With the development of automation technology, some simple quantitative packaging equipment has come into being. Compared with manual packaging, the efficiency has been greatly improved.

[0004] However, the existing equipment still has shortcomings. For example, the equipment can only package materials of a single category or a specific form. Even if the structure is adjusted to accommodate multi-category packaging, the whole machine is merely divided into multiple cavities and multiple packaging pipes. This simple combination and upgrade results in complex control of the valves of each packaging pipeline during each packaging, and the automation level of the whole machine still needs to be further improved. Summary of the invention

[0005] To overcome the above-mentioned defects, the embodiments of the present disclosure provide a quantitative packaging mechanism for bagged multi-category materials, which solves the technical problem of complex valve control of each packaging pipeline when the packaging equipment in the related art performs multi-category packaging.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a quantitative packaging mechanism for bagged multi-category materials, which is used to package food into packaging bags, including: Packaging body; A first dispensing tube and a second dispensing tube, wherein the first dispensing tube and the second dispensing tube are both connected to the dispensing body, the first dispensing tube has a first dispensing port, and the second dispensing tube has a second dispensing port, and the first dispensing port and the second dispensing port are both used to face the bag opening of the packaging bag; An opening and closing member 1, wherein the opening and closing member 1 is movably arranged relative to the dispensing tube 1, and the opening and closing member 1 is used to block or unblock the dispensing tube 1 after being moved; A second opening and closing member, wherein the second opening and closing member is movably arranged relative to the second dispensing pipe, and the second opening and closing member is used to block or unblock the second dispensing pipe after being moved; A rotating member is rotatably arranged on the dispensing main body, and after the rotating member is rotated, it is used to alternately push the opening and closing member 1 and the opening and closing member 2, so that the dispensing tube 1 and the dispensing tube 2 alternately feed materials to the bag opening of the packaging bag.

[0007] For example, in a quantitative filling mechanism for bagged multi-category materials provided by at least one embodiment of the present disclosure, the opening and closing part 1 is swingably set on the filling body, and the opening and closing part 1 is used to open or close the filling port 1 after swinging, and the opening and closing part 2 is a plug-in valve part, and the opening and closing part 2 is movably set relative to the filling tube 2.

[0008] For example, in a quantitative packaging mechanism for multiple categories of bagged materials provided by at least one embodiment of the present disclosure, the packaging tube 1 is vertical, and the end of the packaging tube 2 close to the packaging port 2 is arranged on the opening and closing member 1, and the opening and closing member 1 is used to control the packaging port 2 to be directed toward or away from the bag opening of the packaging bag after being swung.

[0009] For example, at least one embodiment of the present disclosure provides a quantitative packaging mechanism for bagged multi-category materials, further comprising: A bag-supporting frame, wherein the bag-supporting frame is arranged on the packaging body; Two suction cups, both of which are movably arranged on the bag support frame, are spaced apart, and move closer to or farther away from each other after movement. After moving away from each other, the two suction cups are used to open the bag opening of the packaging bag so that the bag opening of the packaging bag can receive food from the first or second dispensing port.

[0010] For example, in a quantitative packaging mechanism for bagged multi-category materials provided by at least one embodiment of the present disclosure, the first packaging tube, the second packaging tube, the first opening and closing member, and the second opening and closing member constitute a packaging unit, and the number of the packaging units is two, and the two packaging units are arranged at intervals, and further includes: Two brackets, both of which are slidably arranged on the sub-packaging body along the circumferential direction of the sub-packaging body, and both of which are provided with the bag-supporting frame; A sealing piece is located at one side of the packaging body. After the bracket slides, it drives the bag support frame to pass through the packaging unit and the sealing piece in sequence. The sealing piece is used to seal the packaging bag.

[0011] For example, at least one embodiment of the present disclosure provides a quantitative packaging mechanism for bagged multi-category materials, further comprising: A sealing member is arranged stationary relative to the packaging body and is located on one side of the packaging body. After the bracket slides, it drives the bag support frame to pass through the packaging tube 1 and the sealing member in sequence. The sealing member is used to seal the packaging bag.

[0012] For example, in a quantitative packaging mechanism for bagged multi-category materials provided in at least one embodiment of the present disclosure, the sealing member includes: A base body, the base body is arranged statically relative to the sub-packaging body and is located at one side of the sub-packaging body; Two sealing frames, both of which are lifted and lowered on the base, the sealing frames are located below the bag-supporting frame, and there is an avoidance gap between the two sealing frames, and the avoidance gap is used for passing the packaging bag; A heat-pressing sealing block is movably arranged on the sealing frame, and the two heat-pressing sealing blocks abut against each other or cancel the abutment after movement, and the heat-pressing sealing block is used to seal the packaging bag.

[0013] For example, in a quantitative packaging mechanism for bagged multi-category materials provided in at least one embodiment of the present disclosure, the sealing member further includes: A support frame, the support frame is movably arranged on the sealing frame and is located above the hot-pressing sealing block, and the moving direction of the support frame is parallel to the moving direction of the hot-pressing sealing block; A shaping roller, the shaping roller is rotatably arranged on the support frame, and the shaping roller is used to shape the surface of the packaging bag; An elastic member, two ends of which are respectively connected to the sealing frame and the supporting frame, and the elastic member provides a force for the two shaping rollers to approach each other.

[0014] For example, at least one embodiment of the present disclosure provides a quantitative packaging mechanism for bagged multi-category materials, further comprising: Two clamps, both of which are movably arranged on the base, both of which are located below the sealing frame and within the avoidance gap, the moving direction of the clamps is parallel to the moving direction of the hot-pressing sealing block, and the two clamps move closer to or farther away from each other after movement, and the clamps are used to clamp the bottom of the packaging bag.

[0015] For example, in a quantitative packaging mechanism for multiple categories of bagged materials provided in at least one embodiment of the present disclosure, the clamp has a clamping portion and an installation portion, the clamping portion is used to clamp the bottom of the packaging bag, and the clamp is movably arranged on the base through the installation portion.

[0016] The beneficial effects of the embodiments of the present disclosure are: 1. Meet the needs of packaging multiple categories of materials: By setting up packaging tube 1 and packaging tube 2, two different categories of food can be packaged at the same time, for example, peanuts (solid food) and soup (liquid food), or mustard tuber (solid food) and soup (liquid food), etc., which meets the packaging needs of multiple categories of materials in the food field and overcomes the limitation that existing equipment can only package single categories or specific forms of materials.

[0017] 2. Simplify the packaging process: There is no need to manually align the openings of different filling tubes with the openings of the packaging bag in sequence as in the existing equipment. Instead, the filling port 1 and the filling port 2 are first arranged in a similar position, and then the two filling tubes are automatically opened and closed in sequence by rotating the rotating part, so that two materials can be packaged at the same time, which simplifies the packaging process and improves the level of automation and packaging efficiency.

[0018] In addition, the opening and closing time of the two groups of filling tubes can be accurately controlled according to the number of rotations of the rotating part, so that different types of food can be accurately and quantitatively loaded into the packaging bag.

DETAILED DESCRIPTION

[0022] The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure.

[0023] In order to simplify the drawings, only the parts related to the disclosure are schematically shown in each figure, and they do not represent the actual structure of the product.

[0027] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] like Figure 1~Figure 3 As shown, it shows a quantitative packaging mechanism for bagged multi-category materials in one embodiment of the present disclosure, which is used for packaging food into a packaging bag 1, including a packaging body 2 connected to a packaging tube 1 3 and a packaging tube 2 4, the packaging tube 1 3 and the packaging tube 2 4 respectively have a packaging port 1 301 and a packaging port 2 401, the packaging port 1 301 and the packaging port 2 401 are both used to face the bag opening of the packaging bag 1; an opening and closing member 1 5 is movably arranged relative to the packaging tube 1 3, and is used to block or unblock the packaging tube 1 3 after the opening and closing member 1 5 is moved; an opening and closing member 2 6 is movably arranged relative to the packaging tube 2 4, and is used to block or unblock the packaging tube 2 4 after the opening and closing member 2 6 is moved; a rotating member 7 is rotatably arranged on the packaging body 2, and is used to alternately push the opening and closing member 1 5 and the opening and closing member 2 6 after the rotation, so that the packaging tube 1 3 and the packaging tube 2 4 alternately feed materials to the bag opening of the packaging bag 1.

[0029] Before normal work, the food materials to be packaged are placed in the corresponding accommodating areas in the packaging body 2 connected to the packaging tube 1 3 and the packaging tube 2 4, such as in a cylinder installed on the top of the packaging body 2 stabilized by the bottom tripod, the cylinder is divided into an upper and lower layer, the packaging tube 1 3 and the packaging tube 2 4 are respectively connected to the upper and lower accommodating areas, such as the upper layer is filled with peanuts, and the lower layer is filled with soup. At this time, the opening and closing part 1 5 blocks the packaging tube 1 3 and the opening and closing part 2 6 blocks the packaging tube 2 4, so that the food materials are prevented from leaking in advance; then the operator stands in a fixed position close to the packaging port 1 301 or the packaging port 2 302 to open the packaging bag 1, or an automatic bag-opening mechanism is arranged at this position, so that the packaging port 1 301 and the packaging port 2 302 can be aligned with the bag opening of the packaging bag 1.

[0030] The packaging mechanism is started, and the rotating member 7 powered by a driving device such as a motor begins to rotate, and its rotation speed is controlled according to a preset packaging program. As the rotating member 7 rotates, a specific pushing structure such as a protrusion and a lever on the rotating member 7 begins to contact and push the opening and closing member 5. Since the opening and closing member 5 is movably arranged relative to the packaging tube 3, the opening and closing member 5 gradually moves under the push of the rotating member 7 until it stops blocking the packaging tube 3, so that the food material in the area connected to the packaging tube 3 in the packaging body 2 will be moved under the action of gravity or pressure. The food material flows into the packaging bag 1 below from the filling port 1 301, and is filled according to the time of pushing the opening and closing member 1 5; the same is true for the filling tube 2 4, and then the rotating member 7 can push the two opening and closing members for a certain period of time respectively when it rotates one circle, and no packaging is performed in the gap where it does not act on the two, and then the opening and closing time of the two groups of filling tubes can be accurately controlled according to the number of rotations of the rotating member 7. Specifically, a photoelectric sensor can be used to calculate the number of rotations, or a rotary encoder can be used to calculate the rotation circumference, so as to realize accurate and quantitative loading of different types of food into the packaging bag 1.

[0031] Finally, the rotating member 7 stops rotating and does not act on the two sets of opening and closing members. The filling tube 1 3 and the filling tube 2 4 are both blocked. Subsequently, the packaging bag 1 containing two materials is transported to the next process, such as sealing, labeling, etc., and the equipment is ready for the next filling operation.

[0032] The opening and closing parts can be selected from gate type, valve type or piston type. For example, the opening and closing parts 1 5 and the opening and closing parts 2 6 are both gate type and can slide horizontally in the filling tube. A sealing rubber strip is provided on the gate to ensure the sealing when the filling tube is blocked. At the same time, two protrusions are integrally formed or welded on the rotating part 7. The two protrusions are located between the two opening and closing parts. When the rotating part 7 rotates, one of the protrusions will first contact one end of the opening and closing part 1 5, pushing the opening and closing part 1 5 to slide in the filling tube 1 3, thereby canceling the blockage of the filling tube 1 3; as the rotating part 7 continues to rotate, the other protrusion will contact one end of the opening and closing part 2 6, pushing the opening and closing part 2 6 to slide in the filling tube 2 4, thereby canceling the blockage of the filling tube 2 4. When the rotating part 7 rotates to the point where the two protrusions do not act on the opening and closing parts, the unloading and packaging is stopped. The same applies to the valve type opening and closing parts or the piston type opening and closing parts.

[0033] The rotating member 7 is selected to push the two groups of opening and closing members alternately in sequence, and the structure is simpler. Compared with the use of complex mechanical arms, connecting rod combinations and other components, or linear reciprocating parts, the design and manufacturing difficulty and cost of the rotating member 7 are also lower; in addition, the rotating member 7 can accurately rotate at a set angle and speed, so as to accurately control the opening and closing sequence and time interval of the opening and closing member 1 5 and the opening and closing member 2 6, to ensure that different materials are packaged according to the preset quantity and sequence, thereby ensuring the packaging quality.

[0034] like Figure 2, Figure 3 As shown, in some examples, the opening and closing member 5 is swingably set on the filling body 2, and the opening and closing member 5 is used to open or close the filling port 301 after swinging. The opening and closing member 2 6 is a plug valve member, and the opening and closing member 2 6 is movably set relative to the filling tube 2 4.

[0035] Since the food material corresponding to the opening and closing member 5 is solid peanuts or mustard tubers, a swing-type opening and closing member 5 is selected so that it can flow smoothly from the filling port 301 when it is swung open to avoid jamming or damage to the food. In addition, the opening and closing member 2 6 is a plug-in valve member, which is also based on the fact that the food material corresponding to the opening and closing member 2 6 is liquid soup, which is more suitable for precise control.

[0036] The selection of the opening and closing parts form, on the one hand, is more suitable for the form of food materials, and on the other hand, makes the overall structure of the equipment more compact, which is conducive to integrating more functions in a limited space.

[0037] Specifically, during the cooperation with the rotating member 7, Figure 3 As shown, the opening and closing member 5 is first controlled to swing through the connecting rod mechanism, and the rotating member 7 in the form of a handle is located between the driving end of the connecting rod mechanism and the moving driving end of the opening and closing member 2 6, that is, between the two thin plates. After the rotating member 7 rotates, the handle pushes the two thin plates in turn to complete the opening and closing of different filling tubes. After one rotation, the unloading time of different filling tubes is the same. The amount of food material in the same packaging bag 1 can be accurately controlled by controlling the number of rotations. When the rotating member 7 rotates until the handle is in the horizontal plane of the rotating shaft, it does not act on the two thin plates, the two filling ports are closed, and the quantitative filling operation is stopped.

[0038] like Figure 2 , Figure 3 As shown, in some examples, the dispensing tube 3 is vertically arranged, and one end of the dispensing tube 4 close to the dispensing port 401 is arranged on the opening and closing member 5, and the opening and closing member 5 is used to control the dispensing port 401 to be oriented toward or away from the bag opening of the packaging bag 1 after swinging.

[0039] The dispensing pipe 3 is arranged vertically, which is conducive to the stable and smooth outflow of solid materials under the action of gravity, and the dispensing pipe 24 is arranged obliquely, so that the liquid material therein can flow out slowly after opening, thereby ensuring the stability of the material flow rate during the dispensing process; in addition, one end of the dispensing pipe 24 close to the dispensing port 2 401 is arranged on the opening and closing member 1 5, and when the opening and closing member 1 5 swings, it can not only control the opening and closing of the dispensing port 1 301, but also adjust the direction of the dispensing port 2 401, so that the dispensing port 2 401 is directed toward or not directed toward the bag opening of the packaging bag 1.

[0040] That is, when the filling port 1 301 is opened and the food materials in the filling tube 1 3 normally fall to the bag opening, the filling port 2 401 swings along with the opening and closing member 1 5 and moves away from the bag opening, thereby preventing the food materials in the filling tube 4 from leaking into the bag opening when the opening and closing member 2 6 is damaged due to long-term operation. Similarly, the packaging accuracy and product quality are prevented from being affected.

[0041] like Figure 4 As shown, in some examples, it also includes: a bag-supporting frame 8 is arranged on the packaging body 2; two suction cup members 9 are movably arranged on the bag-supporting frame 8, and the two suction cup members 9 are arranged at intervals. After the two suction cup members 9 move, they move closer to or away from each other, and after the two suction cup members 9 move away from each other, they are used to open the bag opening of the packaging bag 1, so that the bag opening of the packaging bag 1 can receive the food of the packaging opening 1 301 or the packaging opening 2 401.

[0042] At present, common methods of automatic bag expansion include mechanical clamping and air blowing. When in use, the mechanical clamping clamps the packaging bag 1 from both sides and expands the bag by opening and closing the clamping jaws. This method is suitable for packaging bags 1 with a harder texture and regular shape, but not for soft packaging bags 1 in this context. However, its structure is relatively complex and has poor adaptability to the size and material of the packaging bag 1. The air blowing method is to blow air into the packaging bag 1 and use the gas pressure to expand the packaging bag 1. Although this method is simple and convenient, the bag expansion effect may not be good for soft packaging bags 1 in this context and it is easy to blow food materials away.

[0043] Therefore, a suction cup structure is selected. First, the structure is simple, the cost is low, and it will not affect the internal food materials. In addition, the adsorption method of the suction cup member 9 has good adaptability to packaging bags 1 of different materials, shapes and sizes. Whether it is a paper bag, a plastic bag or a composite material bag, it can be effectively opened to meet diverse packaging needs.

[0044] During the bag-holding process, the packaging bag 1 is first placed in the bag-holding frame 8, just below the dispensing opening 301, in preparation for the bag-holding operation to facilitate subsequent material receiving; then the two suction cups 9 start to move, approach each other and contact the two side surfaces of the packaging bag 1. At the same time, the suction cups 9 start the adsorption function and use vacuum suction to tightly adsorb the two sides of the packaging bag 1; then the two suction cups 9 move in opposite directions and away from each other, thereby opening the bag opening of the packaging bag 1 and placing it in an open state so that the material can be smoothly dispensed into the bag; after the bag opening is opened to an appropriate size, this state is maintained, waiting for the dispensing tube 1 3 and the dispensing tube 2 4 to dispense the material. After the dispensing is completed, the two suction cups 9 return to their initial positions close to each other, stop adsorption, remove the packaging bag 1, and wait for the next packaging operation.

[0045] Specifically, the bag-supporting frame 8 is usually made of a metal or plastic frame structure, which is installed on the packaging body 2 by bolts to ensure that its position is fixed and stable. The size of the bag-supporting frame 8 is designed according to the size of common packaging bags 1, and can accommodate packaging bags 1 of different specifications. The inner walls on both sides provide support and moving tracks for the suction cup member 9; the suction cup member 9 is composed of a suction cup, a vacuum generator and a moving mechanism. The suction cup is made of materials such as rubber or silicone. The vacuum generator is connected to the suction cup through a pipe to provide the vacuum suction required for adsorption, and is pre-connected with an air pump. The moving mechanism can be an electric slider, a cylinder, etc., which drives the suction cup member 9 to move on the bag-supporting frame 8 and is installed on the bag-supporting frame 8 together with two suction cup members 9. The two suction cup members 9 are symmetrically arranged on the bag-supporting frame 8 to ensure that the packaging bag 1 is evenly stressed during the bag-supporting process.

[0046] like Figure 4~Figure 7 As shown, in some examples, a packing tube 1 3, a packing tube 2 4, an opening and closing component 1 5 and an opening and closing component 2 6 constitute a packing unit, there are two packing units, and the two packing units are arranged at an interval; two brackets 10 are both slidably arranged on the packing body 2 along the circumferential direction of the packing body 2, and a bag-supporting frame 8 is arranged on the two brackets 10; a sealing component 11 is located on one side of the packing body 2, and after the bracket 10 slides, it drives the bag-supporting frame 8 to pass through the packing unit and the sealing component 11 in sequence, and the sealing component 11 is used to seal the packaging bag 1.

[0047] Firstly, two filling units arranged at intervals are provided, so that material filling operations can be performed on two packaging bags 1 at the same time, and the materials can be automatically switched to the sealing member 11 for sealing without changing equipment, thereby reducing intermediate links; specifically, a bracket 10 slidingly arranged along the circumferential direction of the filling body 2 is added to drive the bag support frame 8 and the packaging bag 1 thereon to pass through the filling unit and the sealing member 11 in turn, thus forming a continuous and orderly production process. During this process, the packaging bag 1 can complete material filling and sealing operations in turn.

[0048] The bracket 10 can achieve the above-mentioned actions through a track slider structure, a chain sprocket structure or a gear rack structure. For example, in the track slider structure, an annular track is installed in the circumferential direction of the packaging body 2, and a slider compatible with the track is set at the bottom of the bracket 10. The slider slides in the track, thereby realizing the sliding of the bracket 10 along the circumferential direction of the packaging body 2; for example, the gear rack structure, an annular rack is set in the circumferential direction of the packaging body 2, and a gear meshing with the rack is installed on the bracket 10. When the motor drives the gear to rotate, the gear will roll on the rack, thereby driving the bracket 10 to slide in the circumferential direction.

[0049] The sealing member 11 may be in the form of hot pressing sealing, ultrasonic sealing and pulse sealing. For example, ultrasonic sealing is composed of an ultrasonic generator, a transducer, an amplitude transformer and a welding head. The ultrasonic generator converts electrical energy into a high-frequency ultrasonic signal, the transducer converts the ultrasonic signal into mechanical vibration, the amplitude transformer is used to amplify the amplitude of the mechanical vibration, and the welding head transmits the amplified vibration to the sealing part of the packaging bag 1. During operation, when the packaging bag 1 is in the sealing position, the welding head contacts the sealing part of the packaging bag 1 under pressure, and the high-frequency vibration of the ultrasonic wave causes the plastic molecules of the packaging bag 1 to produce intense friction, thereby generating heat to melt the plastic layer and achieve sealing. Another example of pulse sealing is similar to the above. After the packaging bag 1 reaches the sealing position, the pulse transformer is controlled to generate a pulse current, the heating strip is instantly heated up, the sealing part of the packaging bag 1 is melted, and then the cooling device is quickly cooled to complete the sealing.

[0050] In addition, the installation of the bracket 10 and the bag holding frame 8 can be achieved by bolts or cards, for example, a card slot can be set on the bracket 10, and a card block compatible with the card slot can be installed on the bag holding frame 8. The card block is inserted into the card slot to achieve the connection between the bag holding frame 8 and the bracket 10. This connection method is easy to install and disassemble.

[0051] like Figure 7~Figure 8 As shown, in some examples, the sealing member 11 includes: a base 1101 is statically arranged relative to the packaging body 2, and is located on one side of the packaging body 2; two sealing frames 1102 are both raised and lowered on the base 1101, the sealing frames 1102 are located below the bag support frame 8, and there is an avoidance gap 1103 between the two sealing frames 1102, and the avoidance gap 1103 is used to pass the packaging bag 1; a hot pressure sealing block 1104 is movably arranged on the sealing frame 1102, and the two hot pressure sealing blocks 1104 abut against each other or cancel the abutment after moving, and the hot pressure sealing block 1104 is used to seal the packaging bag 1.

[0052] The use of hot-pressing sealing melts and fuses the plastic layers of the packaging material together at high temperature to form a tight sealing structure, which can effectively prevent external factors such as air, moisture and microorganisms from entering the packaging bag 1, and can be applied to a variety of thermoplastic plastic packaging materials, such as common polyethylene PE, polypropylene PP, polyvinyl chloride PVC, etc., which are more suitable for the packaging bag 1 used in this context, and the cost is relatively low.

[0053] During specific operation, the bracket 10 slides and drives the bag support frame 8 to move, and moves the packaging bag 1 filled with materials to just below the sealing member 11. At this time, the packaging bag 1 is located between the two sealing frames 1102, and then the two sealing frames 1102 rise synchronously on the base 1101 through components such as motors or cylinders until the packaging bag 1 passes through the avoidance gap 1103, so that the two hot-pressing sealing blocks 1104 are located at a suitable sealing position, and then the two hot-pressing sealing blocks 1104 are approached to each other on the sealing frame 1102 through components such as motors or cylinders until they abut. During the movement process, the heating element inside the hot-pressing sealing block 1104 has been preheated to the set temperature in advance, and then the high temperature is transferred to the packaging bag 1, so that the plastic layer at the sealing part of the packaging bag 1 is melted, and under a certain pressure and temperature, the sealing operation is completed, and finally reset, the bracket 10 continues to slide, driving the bag support frame 8 to enter the next working cycle.

[0054] The base 1101 is fixed to one side of the sub-packaging body 2 as a support during the whole process, and a guide rail or a slide groove is processed on it for installing and guiding the lifting movement of the sealing frame 1102; The sealing frame 1102 is similar to the bag supporting frame 8, except that there are two of them, and an avoidance gap 1103 is formed between the two to avoid affecting the circulation process of the packaging bag 1; in addition, the hot pressure sealing block 1104 is installed on the inner wall of the sealing frame 1102, and a horizontal guide rail or slide groove is processed on the inner wall. The hot pressure sealing block 1104 cooperates with the guide rail or slide groove through a slider to achieve horizontal movement, and a motor for driving the hot pressure sealing block 1104 to move is installed on the sealing frame 1102 to drive it to move horizontally.

[0055] like Figure 8~Figure 10 As shown, in some examples, the sealing member 11 also includes: a support frame 1105 is movably set on the sealing frame 1102, located above the hot pressing sealing block 1104, and the moving direction of the support frame 1105 is parallel to the moving direction of the hot pressing sealing block 1104; a shaping roller 1106 is rotatably set on the support frame 1105, and the shaping roller 1106 is used to shape the surface of the packaging bag 1; the two ends of the elastic member 1107 are respectively connected to the sealing frame 1102 and the support frame 1105, and the elastic member 1107 provides a force for the two shaping rollers 1106 to approach each other.

[0056] After the packaging bag 1 is sealed, wrinkles and unevenness may appear on its surface, affecting the overall appearance of the product. At the same time, solid food and liquid food in the packaging bag 1 may accumulate at the bottom, and then the surface of the product will become more irregular during the vacuuming process after sealing, affecting subsequent palletizing or boxing operations, so two sets of shaping rollers 1106 are added.

[0057] Specific process, such as Fig. 9As shown, under the action of the elastic member 1107, the support frame 1105 makes the two shaping rollers 1106 approach each other and be in a standby state, and at the same time, the hot pressing sealing block 1104 is also in the initial position, located below the shaping roller 1106, waiting for the packaging bag 1 to be in place; Fig.10 As shown, after the packaging bag 1 is in place and before the hot-pressing sealing, that is, during the rising process of the sealing frame 1102, the two shaping rollers 1106 approach each other and contact to squeeze and shape the surface of the packaging bag 1, so that the shape of the packaging bag 1 is more regular and material accumulation is avoided, until the hot-pressing sealing position is reached and the sealing is completed.

[0058] It is worth mentioning that after sealing, vacuuming and unloading operations should be performed to avoid failure of the shaping effect and keep the surface of the packaging bag 1 as flat as possible. Therefore, the packaging bag 1 can be vacuumed at this position after sealing and before unloading. In simple terms, the external vacuuming method can be used, the vacuum nozzle is inserted into the packaging bag 1, and the vacuum pump is started to extract the excess air inside; finally, the unloading is reset, and the excess packaging bag 1 connected to the suction cup 9 at the top is cut off using the cutter on the hot pressing sealing block 1104, and then the packaging bag 1 is removed.

[0059] like Figure 8~Figure 10 As shown, in some examples, it also includes: two splints 12 are movably set on the base 1101, the two splints 12 are located below the sealing frame 1102, and are located in the avoidance gap 1103, the moving direction of the splint 12 is parallel to the moving direction of the hot pressing sealing block 1104, and the two splints 12 move closer to or away from each other, and the splint 12 is used to clamp the bottom of the packaging bag 1.

[0060] During the hot-pressing sealing and shaping operations, the clamping plate 12 clamps the bottom of the packaging bag 1, which can effectively fix the position of the packaging bag 1, prevent the packaging bag 1 from shifting or shaking during the sealing process, and also help improve the quality and accuracy of sealing and shaping.

[0061] What is different from the above process after adding the splint 12 is that before the sealing frame 1102 rises, after the packaging bag 1 is in place, the splint 12 is controlled to move toward each other in a direction parallel to the moving direction of the hot-press sealing block 1104, and finally clamps the bottom of the packaging bag 1. In order not to interfere with the movement of the packaging bag 1, the splint 12 also needs to be arranged in the avoidance gap 1103; and when the material is finally unloaded, the splint 12 is reset, the packaging bag 1 is released, and a new working cycle begins.

[0062] like Fig.10 As shown, in some examples, the clamping plate 12 has a clamping portion 1201 and a mounting portion 1202 , the clamping portion 1201 is used to clamp the bottom of the packaging bag 1 , and the clamping plate 12 is movably disposed on the base 1101 through the mounting portion 1202 .

[0063] Specifically, the clamping plate 12 can be designed to be L-shaped, and has a vertical clamping portion 1201 that can better fit the shape of the packaging bag 1, thereby increasing the clamping force of the clamping plate 12 on the packaging bag 1. In addition, it has an installation portion 1202 for connecting to the base 1101, so that the motor and other structures arranged on the base 1101 can drive the L-shaped clamping plate 12 to move stably.
