Description

Technical Field

[0001] The present invention relates to the field of packaging machines, in particular to a horizontal bag-feeding packaging machine for stably transmitting packaging bags. Background Art

[0002] The horizontal bag-feeding packaging machine is an advanced automated packaging equipment. It uses a horizontal conveyor belt to transport pre-made packaging bags and uses mechanical devices to automatically complete a series of packaging processes such as bag opening, bag removal, loading, filling, and sealing. Its high degree of automation reduces manual operations and can effectively improve packaging efficiency and quality. It is suitable for continuous packaging operations in various industries and meets the needs of large-scale production and rapid packaging.

[0003] In the existing technology, when performing automated bag packaging, it is necessary to pay attention to maintaining stability during the transportation process, and it is necessary to only transport one packaging bag at a time to avoid the packaging bag falling during the transportation process. At the same time, it is necessary to transport through a single packaging bag, which is beneficial to avoid the situation where excess packaging bags are transported during the transportation process due to lack of clamping and fall, thereby improving the stability of the packaging. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a horizontal bag feeding packaging machine for stably transmitting packaging bags.

[0005] The present invention provides a horizontal bag feeding packaging machine for stably conveying packaging bags, comprising a main frame and further comprising:

[0006] A single material taking unit is installed on one end edge of the main frame and is used to support the packaging bag;

[0007] A transfer unit is installed at one end of the main frame and is used to cooperate with the single material taking unit to realize single material taking of packaging bags;

[0008] an opening unit, which transports the packaging bag from the transfer unit to the opening unit through a lower conveying assembly, and the opening unit opens the opening of the packaging bag by negative pressure;

[0009] The feeding unit transports the packaging bags to the feeding unit for packaging through the alternating transport of the lower conveying assembly and the upper conveying assembly;

[0010] The sealing unit transports the packaging bag to the sealing unit for sealing the packaging bag through the alternating transport of the lower conveying assembly and the upper conveying assembly;

[0011] The single picking unit is installed on the edge of one end of the main frame. It can accurately support and grab a single packaging bag, ensuring that only one packaging bag is taken at a time, providing a stable foundation for subsequent processes. The transfer unit cooperates with the single picking unit to perform a preliminary transfer operation on the grabbed packaging bag, so that it can smoothly enter the next link. The opening unit obtains the packaging bag with the help of the lower conveying component and uses the negative pressure to open the opening of the packaging bag. This process prepares for the subsequent material filling. The feeding unit, under the alternating conveying action of the lower conveying component and the upper conveying component, accurately transports the opened packaging bag to the designated position for material packaging to ensure that the material can be accurately After being put into the packaging bag, the sealing unit also transports the completed material-packed packaging bag to itself through the alternating transportation of the lower conveying component and the upper conveying component, seals the packaging bag, and completes the entire packaging process, thereby effectively avoiding the packaging bag from falling during the transportation process. Since only one packaging bag is transported at a time, and the stable clamping and orderly transportation of each unit are used to ensure the stability of the packaging bag in each link, thereby greatly improving the stability and reliability of the packaging, improving the overall packaging efficiency and quality, and reducing the production failure rate caused by problems such as bag jamming and bag dropping, making the entire automated bag packaging process smoother and more efficient.

[0012] Preferably, the single reclaiming unit comprises:

[0013] a bag packing platform fixed inside the main frame;

[0014] A plurality of adjustment limit rods are slidably mounted on the top of the packaging bag platform and are used to limit the position of the packaging bag by adjustment;

[0015] A material taking port is provided through the top of the bag packaging platform;

[0016] a first cylinder fixed inside the main frame and located directly below the bag packaging platform;

[0017] a lifting frame fixed to the end of the telescopic rod of the first cylinder;

[0018] A plurality of suction cups are fixed to the top of the lifting frame and are located directly below the material taking port, and the suction cups are connected to an air pressure pump;

[0019] The packaging bags are placed on the packaging bag table, and the limit rod can be adjusted to adapt to packaging bags of different sizes and limit their position to ensure that the packaging bags are arranged neatly. When taking materials, the first cylinder drives the lifting frame to move upward, so that the suction cup contacts the bottom of the packaging bag, the air pressure pump starts to generate negative pressure, and the suction cup absorbs the packaging bags on the bottom layer. Then the cylinder drives the lifting frame to move downward. Because other packaging bags are limited by the packaging bag table, only the adsorbed packaging bags move downward through the material taking port through their own deformation, so that only the adsorbed packaging bags move downward, realizing single-bag taking. After that, the transfer unit cooperates to transfer the taken packaging bags to the next link. By adjusting the limit rod in conjunction with the cylinder and the suction cup, a single packaging bag can be taken accurately and stably at a time to avoid multiple taking or unstable bag taking causing it to fall, providing stable bag supply for subsequent opening, feeding, sealing and other processes, ensuring the packaging efficiency and quality of the whole machine, and adapting to different packaging bag sizes with strong versatility.

[0020] Preferably, the transfer unit includes:

[0021] a bracket, fixed inside the main frame;

[0022] a first motor, fixed to a side wall of the bracket;

[0023] A turning frame, fixed to the end of the output shaft of the first motor;

[0024] A turning clamp is installed at the bottom end of the turning frame and is driven by a driving motor to achieve clamping;

[0025] After the packaging bag is adsorbed by the material taking unit, the first motor starts to drive the turning frame to rotate. The turning clamp at the bottom of the turning frame is controlled by the driving motor to perform a clamping action, thereby clamping and turning the packaging bag, turning the packaging bag from a horizontal state to a vertical open state and conveying it to the next process. The flipping and transfer of the packaging bag can be achieved quickly and accurately, ensuring the stability of the packaging bag during the conveying process and the accuracy of the opening, providing strong support for subsequent opening, feeding and other processes, and improving the automation level and work efficiency of the entire packaging process.

[0026] Preferably, the lower conveying assembly comprises:

[0027] Two edge frames are slidably mounted on the inner wall of the main frame;

[0028] Two first translation frames are telescopically mounted on opposite sides of the two edge frames;

[0029] a first driving member fixed inside the main frame, for driving the first translation frame to move laterally and vertically along a horizontal position;

[0030] two clamping members fixed to opposite sides of one end of the first translation frame facing the transfer unit;

[0031] a plurality of first clamping ends fixed in a linear array to opposite sides of the two first translation frames;

[0032] The first driving member drives the first translation frame to move laterally and vertically along the horizontal position, and the first translation frame drives the clamping member fixed thereon to move synchronously, and the first clamping ends on the clamping members are arranged in a linear array, which can accurately clamp the packaging bag and transport it from one position to another. When the transfer unit transfers the packaging bag to a vertical state, the first driving member drives the first translation frame to move in the vertical direction to the bottom of the transfer unit, and then drives the two first translation frames to move laterally, so that the two first translation frames approach each other, thereby driving the two clamping members to approach each other to clamp the packaging bag in the vertical state. Subsequently, when the first driving member drives the first translation frame to move, it can drive the packaging bag to move vertically to the bottom of the opening unit, thereby facilitating the opening of the packaging bag;

[0033] When the packaging bag is opened by the opening unit, the first driving member drives the two first translation racks to move horizontally and away from each other, so as to drive the two clamping members to move away from each other and release the packaging bag. Then, when the first driving member moves vertically again to drive the clamping member to move to the bottom of the transfer unit, the first clamping end at the rear moves to the bottom of the opening unit. At this time, when the first driving member drives the two first products to move horizontally and approach each other, the two clamping members approach each other to clamp the new packaging bag, and the two first clamping ends approach each other to clamp the packaging bag after the opening is opened. Then, when the first driving member drives the two first translation racks to move horizontally, the new packaging bag can be driven to the bottom of the opening unit, and the packaging bag after the opening is opened reaches the bottom of the feeding unit and is then fed. In this way, the packaging bag is conveyed reciprocally to ensure the stability and accuracy of the entire conveying process.

[0034] Through the precise control of the first translation frame by the first driving member, the packaging bags can be flexibly conveyed in the horizontal and vertical directions, meeting the packaging needs between different workstations, and improving the versatility and adaptability of the equipment. The design of the clamping member and the first clamping end can ensure that the packaging bags are stably clamped during the conveying process, avoiding the packaging bags from falling or tilting due to unstable conveying, thereby improving the stability and reliability of the packaging. The alternating use of the lower conveying component and the upper conveying component can form a continuous and efficient material conveying process, improve the automation level and production efficiency of the entire packaging machine, reduce manual intervention, and reduce labor intensity and production costs.

[0035] Preferably, the lower conveying assembly further comprises:

[0036] Two inner grooves are respectively provided inside the two clamping members;

[0037] Two groups of air flushing tubes, with multiple air flushing tubes forming one group. The air flushing tubes in the same group are arranged in a linear array inside the clamping member, with one end obliquely extending upward through the clamping member toward a side wall of the other clamping member, and the other end communicating with one end of the inner groove toward the first translation frame;

[0038] Two pistons are slidably mounted inside the two inner grooves respectively;

[0039] Two sets of connecting rods are respectively fixed to the opposite ends of the two pistons, and the two sets of connecting rods respectively pass through the first translation frame and then connect to the edge frame;

[0040] When the bag is in the process of being clamped by the clamping member, the two clamping members move relative to each other, thereby causing the two clamping members to move away from the edge frame. In the process of the clamping member moving away from the edge frame, the clamping member moves relative to the connecting rod, thereby causing the connecting rod to drive the piston to move inside the inner groove, thereby pushing the gas inside the inner groove to be ejected along the air flushing tube, thereby pushing the bag upward through the air flow during the clamping process. At this time, when the clamping member is close to the bag, the flip clamp releases the clamping of the bag, thereby causing the bag to be briefly suspended in the air before being clamped by the clamping member. The bag in the suspended state can be pushed upward under the impact of the upward air flow, thereby pushing the bag downward when the clamping position of the bag is biased upward, thereby pushing the clamping position of the bag downward, so as to avoid the situation in which the bag falls due to the clamping position of the bag being biased downward during the transfer and clamping process, thereby improving the stability of the bag clamping.

[0041] At the same time, a stopper is provided on one side of one of the flip clamps facing the other flip frame, so that when the packaging bag is pushed upward by the air impact, the upwardly moving packaging bag can be limited, thereby preventing the upwardly moving packaging bag from excessively moving upward and causing unstable clamping, thereby improving the stability of the packaging bag clamping;

[0042] Through the cooperation of the piston and the connecting rod, combined with the sliding installation of the edge frame, the lower conveying component can flexibly adjust the position of the packaging bag according to the needs of the packaging process, enhancing the versatility and adaptability of the equipment. Multiple air injection tubes are distributed in a linear array, which can evenly apply airflow to the packaging bag, effectively preventing the packaging bag from shifting or tilting during the adjustment process, ensuring the accuracy and stability of the adjustment. This design not only improves the stability and reliability of the packaging, but also optimizes the smoothness of the entire packaging process, providing a strong guarantee for high-efficiency automated packaging.

[0043] Preferably, the upper conveying assembly includes:

[0044] Two second translation frames are respectively installed inside the main frame through second driving members to drive the second translation frames to move laterally and vertically along the horizontal position;

[0045] Two groups of third clamping ends, with multiple third clamping ends forming one group, mounted in a linear array on opposite sides of the two second translation frames;

[0046] The second translation frame is driven by the second driving member and can move horizontally and vertically. The third clamping end is installed in a linear array on the opposite side of the second translation frame and works in conjunction with the lower conveying assembly. When the packaging bag is conveyed, the lower conveying assembly first conveys the packaging bag to the specified position. At this time, the third clamping end of the upper conveying assembly clamps the packaging bag, and the second driving member drives the second translation frame to move to realize continued conveying of the packaging bag. Its clamping method cooperates with the lower conveying assembly to ensure the stability of the packaging bag during the conveying process. The upper conveying assembly and the lower conveying assembly work alternately to realize continuous and smooth material conveying, improve packaging efficiency, ensure that the packaging bag is firmly clamped, prevent deviation or falling during transportation, improve packaging quality, reduce production failure rate, enhance equipment reliability, reduce manual intervention, and reduce labor intensity and production costs.

[0047] Preferably, the opening unit comprises:

[0048] Two connecting frames, respectively slidably mounted on the top of the two second translation frames, and mounted on the side walls of the main frame via telescopic driving members;

[0049] Two sets of second clamping ends are respectively fixed to opposite sides of the two connecting frames;

[0050] Two suction cups are respectively mounted on the two connecting frames through telescopic drive members and are connected to a negative pressure pump;

[0051] After the packaging bag is transported to the opening unit by the upper conveying assembly, when the second driving member drives the second translation frame to move vertically, due to the sliding connection between the connecting frame and the second translation frame, the movement of the connecting frame will not be driven. When the second driving member drives the second translation frame to move horizontally, the telescopic driving member cooperates at the same time to make the connecting frame move horizontally synchronously, thereby driving the two connecting frames to move relative to each other, so that the second clamping end approaches and clamps the two sides of the packaging bag. At the same time, the two suction cups on the connecting frame approach each other to clamp the packaging bag, and then the negative pressure pump is started to use the negative pressure to adsorb the opening of the packaging bag. Then the two corresponding telescopic driving members drive the two suction cups away from each other to drive the opening of the packaging bag to open, preparing for subsequent material filling. Through the cooperation of the connecting frame and the telescopic driving member, the second clamping end can accurately clamp the packaging bag to ensure its stable position during the opening process. The synergistic effect of the suction cup and the negative pressure pump can reliably open the opening of the packaging bag, ensuring that subsequent material filling is carried out smoothly, improving the overall packaging efficiency and quality, reducing the packaging error rate caused by opening failure, and enhancing the reliability and automation of the equipment.

[0052] Preferably, the opening unit further includes:

[0053] a laser light fixed at the center of one of the suction cups;

[0054] a light developing chamber fixedly connected to the middle portion of the connecting pipe of the other suction cup;

[0055] A reflector is installed inside the light display chamber, and when there is no packaging bag blocking the two suction cups, the light of the laser lamp enters the light display chamber and is reflected by the reflector to illuminate the light display chamber;

[0056] When a bag enters the opening unit, the suction cups, under the action of a negative pressure pump, attempt to absorb and open the bag's opening. At this point, a laser light is located at the center of one of the suction cups, and a light display chamber is connected to the middle of the connecting tube of the other suction cup. When there is no bag blocking the space between the two suction cups, the light emitted by the laser light can smoothly enter the light display chamber, where it is reflected by the reflector and illuminated, thus forming an optical path detection mechanism to determine whether the bag is correctly clamped. This optical detection method can quickly and accurately determine whether the bag is properly conveyed and clamped, ensuring the accuracy of subsequent material filling. If the light is blocked, it indicates that the bag is properly clamped between the two sets of second clamping ends. If the light is not blocked, it means that there is no bag between the two sets of second clamping ends, indicating that the bag is not clamped by the second clamping ends. The failure to open the bag can be immediately detected and appropriate measures can be taken, improving the reliability and stability of the entire packaging process. This non-contact detection method does not cause physical damage to the bag, ensuring the integrity of the package. It also has a rapid response and can be seamlessly integrated with the automated packaging process to improve overall production efficiency.

[0057] Preferably, it also includes:

[0058] Two electromagnets, respectively fixed to the bottoms of opposite sides of the two first translation frames;

[0059] Two magnets are slidably mounted on top of opposite sides of the two first translation frames;

[0060] Two sets of fourth clamping ends are respectively installed on opposite sides of the two magnets;

[0061] When the display chamber is illuminated, the electromagnet is energized to generate a magnetic field, which pushes the magnet slidably installed on the top of the opposite side of the first translation frame, so that the magnet drives the fourth clamping end to move upward, thereby driving the clamped packaging bag to move upward for lifting, so that when the packaging bag is positioned but not between the two second clamping ends, it can be pushed to move upward, thereby pushing the packaging bag to reach between the two second clamping ends, which is conducive to the stable clamping and conveying of the packaging bag. Through the interaction between the electromagnet and the magnet, the packaging bag is lifted, the stability of the packaging bag during opening and conveying is improved, and the packaging bag is avoided from being offset or falling off due to unstable clamping, thereby improving the reliability and automation level of the entire packaging equipment.

[0062] Preferably, the opening unit further includes:

[0063] Two annular rings are respectively installed on the opposite side edges of the two suction cups, and the annular rings are both provided with a metal frame wrapped with a rubber sleeve;

[0064] Two groups of circular holes, one group in an arc-shaped array is opened above the edge of one of the annular rings, and the other group in an arc-shaped array is opened below the edge of the other annular ring;

[0065] Two connecting pipes are connected to the annular rings on the two suction cups respectively, and are arranged in the upside-down direction opposite to the circular holes. The other ends of the two connecting pipes are connected to air pumps to deliver high-temperature and low-temperature airflows respectively.

[0066] In the process of sucking and opening the opening of the packaging bag, when negative pressure adsorption is performed inside the suction cup, high-temperature and low-temperature airflows are respectively transported to the interior of the two suction pipes through two connecting pipes, so that the high-temperature and low-temperature airflows flow through the annular ring for a circle and then enter the interior of the suction cup along the circular hole, so that the packaging bag meets inside the suction cup. When the hot and cold meet, due to the heat conduction effect of the metal frame and the fact that the interior of the transported high-temperature and low-temperature airflows contains some water vapor, the water vapor condenses when the hot and cold meet, so that a small amount of condensed water vapor is generated on the edge of the suction cup, making it more stable during the suction cup adsorption process, which is beneficial to improving the stability when adsorbing the packaging bag opening.

[0067] Compared with the prior art, the present invention has the following beneficial effects:

[0068] 1. Through the stable clamping and orderly conveying of each unit, the stability of the packaging bag in each link is guaranteed, thereby greatly improving the stability and reliability of the packaging, improving the overall packaging efficiency and quality, and reducing the production failure rate caused by problems such as bag jamming and bag dropping, making the entire automated bag feeding and packaging process smoother and more efficient.

[0069] 2. Through the cooperation of the piston and connecting rod, combined with the sliding installation of the edge frame, the lower conveying assembly can flexibly adjust the position of the packaging bag according to the needs of the packaging process, enhancing the versatility and adaptability of the equipment. Multiple air injection tubes are distributed in a linear array, which can evenly apply airflow to the packaging bag, effectively preventing the packaging bag from shifting or tilting during the adjustment process, ensuring the accuracy and stability of the adjustment. This design not only improves the stability and reliability of the packaging, but also optimizes the smoothness of the entire packaging process, providing a strong guarantee for high-efficiency automated packaging.

[0070] 3. This optical detection method can quickly and accurately determine whether the packaging bag is being conveyed and clamped normally, ensuring the accuracy of subsequent material filling. If the light is blocked, it means that the packaging bag is normally clamped between the two sets of second clamping ends. If the light is not blocked, it means that there is no packaging bag between the two sets of second clamping ends, which means that the packaging bag is not clamped by the second clamping ends. In this way, the opening failure can be detected immediately and corresponding processing can be performed, thereby improving the reliability and stability of the entire packaging process. This non-contact detection method will not cause physical damage to the packaging bag, ensuring the integrity of the packaging, and has a fast response. It can be seamlessly connected with the automated packaging process to improve overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0083] like Figures 1 to 10 The horizontal bag-feeding packaging machine for stably conveying packaging bags shown includes a main frame 1 and further includes:

[0084] A single material taking unit 101 is installed on one end edge of the main frame 1 and is used to support the packaging bag;

[0085] The transfer unit 102 is installed at one end of the main frame 1 and is used to cooperate with the single material taking unit 101 to realize single material taking of packaging bags;

[0086] The opening unit 103 transports the packaging bag from the transfer unit 102 to the opening unit 103 through the lower conveying assembly, and the opening unit 103 opens the opening of the packaging bag by negative pressure;

[0087] The feeding unit 104 delivers the packaging bags to the feeding unit 104 for packaging of the materials through alternating conveying of the lower conveying assembly and the upper conveying assembly;

[0088] The sealing unit 105 transports the packaging bags to the sealing unit 105 for sealing the packaging bags through alternating transport of the lower conveying assembly and the upper conveying assembly;

[0089] In the prior art, when performing automated bag feeding and packaging, it is necessary to maintain stability during the conveying process and to convey only one bag at a time to prevent the bag from falling during the conveying process. At the same time, conveying by a single bag is necessary to prevent the excess bags from falling due to lack of clamping during the conveying process, thereby improving the stability of the packaging.

[0090] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: the single material-taking unit 101 is installed at the edge of one end of the main frame 1. It can accurately support and grab a single packaging bag, ensuring that only one packaging bag is taken at a time, providing a stable foundation for subsequent processes. The transfer unit 102 cooperates with the single material-taking unit 101 to perform a preliminary transfer operation on the grabbed packaging bag so that it can smoothly enter the next link. The opening unit 103 obtains the packaging bag with the help of the lower conveying component and uses the negative pressure to open the opening of the packaging bag. This process prepares for subsequent material filling. The feeding unit 104 accurately transports the opened packaging bag to the designated position under the alternating conveying action of the lower conveying component and the upper conveying component. , to pack the materials and ensure that the materials can be accurately loaded into the packaging bags. The sealing unit 105 also transports the packaging bags with completed material packing to itself through the alternating transportation of the lower conveying component and the upper conveying component, and seals the packaging bags to complete the entire packaging process, thereby effectively avoiding the packaging bags from falling during the transportation process. Since only one packaging bag is transported at a time, and the stable clamping and orderly transportation of each unit are used to ensure the stability of the packaging bags in each link, thereby greatly improving the stability and reliability of the packaging, improving the overall packaging efficiency and quality, and reducing the production failure rate caused by problems such as bag jamming and bag dropping, making the entire automated bag feeding and packaging process smoother and more efficient.

[0091] As an optional embodiment, the single reclaiming unit 101 includes:

[0092] The bag packing platform 2 is fixed inside the main frame 1;

[0093] A plurality of adjustment limit rods 202 are slidably mounted on the top of the bag packaging platform 2 and are used to limit the position of the bag by adjustment;

[0094] The material taking port 201 is opened through the top of the bag packaging platform 2;

[0095] The first cylinder 204 is fixed inside the main frame 1 and is located directly below the bag packaging platform 2;

[0096] The lifting frame 203 is fixed to the end of the telescopic rod of the first cylinder 204;

[0097] A plurality of suction cups 205 are fixed to the top of the lifting frame 203 and are located directly below the material taking port 201. The suction cups 205 are connected to an air pressure pump.

[0098] The packaging bags are placed on the packaging bag platform 2. The position of the limit rod 202 can be adjusted to accommodate packaging bags of different sizes and limit their position to ensure that the packaging bags are neatly arranged. When taking materials, the first cylinder 204 drives the lifting frame 203 to move upward, so that the suction cup 205 contacts the bottom of the packaging bags. The air pressure pump starts to generate negative pressure, and the suction cup 205 absorbs the packaging bags at the bottom. Then the cylinder drives the lifting frame 203 to move downward. Because other packaging bags are limited by the packaging bag platform 2, only the absorbed packaging bags are lifted up by their own shape. It moves downward through the material taking port 201, so that only the sucked packaging bags move downward, realizing single-time single-bag taking. Then the transfer unit 102 cooperates to transfer the taken packaging bags to the next link. By adjusting the limit rod 202 in conjunction with the cylinder and the suction cup 205, a single packaging bag can be taken accurately and stably at a time, avoiding multiple taking or unstable bag taking causing it to fall, providing a stable bag supply for subsequent opening, feeding, sealing and other processes, ensuring the packaging efficiency and quality of the whole machine, and adapting to different packaging bag sizes, with strong versatility.

[0099] As an optional embodiment, the forwarding unit 102 includes:

[0100] Bracket 3, fixed inside the main frame 1;

[0101] The first motor 301 is fixed on the side wall of the bracket 3;

[0102] The turning frame 302 is fixed to the output shaft end of the first motor 301;

[0103] The flip clamp 303 is installed at the bottom end of the flip frame 302 and is driven by a drive motor to achieve clamping;

[0104] After the packaging bag is adsorbed by the material picking unit, the first motor 301 starts to drive the turning frame 302 to rotate. The turning clamp 303 at the bottom of the turning frame 302 is controlled by the driving motor to perform a clamping action, thereby clamping and turning the packaging bag, turning the packaging bag from a horizontal state to a vertical open state and conveying it to the next process, quickly and accurately turning and transferring the packaging bag, ensuring the stability of the packaging bag during the conveying process and the accuracy of the opening, providing strong support for subsequent opening, feeding and other processes, and improving the degree of automation and work efficiency of the entire packaging process.

[0105] As an optional embodiment, the lower conveying assembly includes:

[0106] Two edge frames 401 are slidably mounted on the inner wall of the main frame 1;

[0107] Two first translation frames 4 are telescopically mounted on opposite sides of the two edge frames 401;

[0108] The first driving member 402 is fixed inside the main frame 1 and is used to drive the first translation frame 4 to move horizontally and vertically along the horizontal position;

[0109] Two clamping members 403 are fixed to opposite sides of one end of the first translation frame 4 facing the transfer unit 102;

[0110] A plurality of first clamping ends 404 are fixed in a linear array to opposite sides of the two first translation frames 4;

[0111] The first driving member 402 drives the first translation frame 4 to move laterally and vertically along the horizontal position, and the first translation frame 4 drives the clamping member 403 fixed thereon to move synchronously. The first clamping ends 404 on the clamping members 403 are arranged in a linear array, which can accurately clamp the packaging bag and transport it from one position to another. When the transfer unit 102 transfers the packaging bag to the vertical state, the first driving member 402 drives the first translation frame 4 to move in the vertical direction to the bottom of the transfer unit 102, and then drives the two first translation frames 4 to move laterally, so that the two first translation frames 4 approach each other, thereby driving the two clamping members 403 approach each other to clamp the packaging bag in the vertical state. Subsequently, when the first driving member 402 drives the first translation frame 4 to move, it can drive the packaging bag to move vertically to the bottom of the opening unit 103, thereby facilitating the opening of the packaging bag.

[0112] When the packaging bag is opened by the opening unit 103, the first driving member 402 drives the two first translation racks 4 to move horizontally and away from each other, so as to drive the two clamping members 403 to move away from each other and release the packaging bag. Subsequently, the first driving member 402 moves vertically again to drive the clamping members 403 to move to the bottom of the transfer unit 102, and at the same time, the rear first clamping end 404 moves to the bottom of the opening unit 103. At this time, when the first driving member 402 drives the two first products to move horizontally and approach each other, the two clamping members 403 approach each other to clamp the new packaging bag, and the two first clamping ends 404 approach each other to clamp the packaging bag after the opening is opened. Subsequently, when the first driving member 402 drives the two first translation racks 4 to move horizontally, the new packaging bag can be driven to the bottom of the opening unit 103, and the packaging bag after the opening is reached to the bottom of the feeding unit 104 and then fed. In this way, the packaging bag is transported back and forth to ensure the stability and accuracy of the entire transportation process.

[0113] Through the precise control of the first translation frame 4 by the first driving member 402, the packaging bags can be flexibly transported in the horizontal and vertical directions, meeting the packaging needs between different workstations, and improving the versatility and adaptability of the equipment. The design of the clamping member 403 and the first clamping end 404 can ensure that the packaging bags are stably clamped during the transportation process, avoiding the packaging bags from falling or tilting due to unstable transportation, thereby improving the stability and reliability of the packaging. The alternating use of the lower conveying component and the upper conveying component can form a continuous and efficient material conveying process, improve the automation level and production efficiency of the entire packaging machine, reduce manual intervention, and reduce labor intensity and production costs.

[0114] As an optional embodiment, the lower conveying assembly further includes:

[0115] Two inner grooves 501 are respectively provided inside the two clamping members 403;

[0116] Two groups of air flushing tubes 5, with multiple air flushing tubes 5 forming one group, are arranged in a linear array inside the clamping member 403, with one end of the air flushing tubes 5 extending upwardly and obliquely through the side wall of the clamping member 403 toward the other clamping member 403, and the other end communicating with one end of the inner groove 501 toward the first translation frame 4;

[0117] Two pistons 502 are slidably mounted inside the two inner grooves 501 respectively;

[0118] Two sets of connecting rods 503 are fixed to the opposite ends of the two pistons 502, and the two sets of connecting rods 503 pass through the first translation frame 4 and then connect to the edge frame 401;

[0119] In the process of the packaging bag being clamped by the clamping member 403, the two clamping members 403 move relative to each other, thereby causing the two clamping members 403 to move away from the edge frame 401. In the process of the clamping member 403 moving away from the edge frame 401, the clamping member 403 moves relative to the connecting rod 503, so that the connecting rod 503 drives the piston 502 to move inside the inner groove 501, thereby pushing the gas inside the inner groove 501 to be ejected along the air flushing tube 5, thereby pushing the packaging bag upward through the air flow during the clamping process. At this time, when the clamping member 403 is close to the packaging bag, The flip clamp 303 releases the grip of the packaging bag, so that the packaging bag is briefly suspended in the air before being clamped by the clamping member 403. The packaging bag in the suspended state can be pushed upward by the upward airflow, so that when the clamping position of the packaging bag is upward, the packaging bag can be pushed downward, thereby pushing the clamping position of the packaging bag downward, which is beneficial to avoid the situation in which the packaging bag falls due to the clamping position of the packaging bag being too low, thereby improving the stability of the clamping of the packaging bag;

[0120] At the same time, a stopper is provided on one side of one of the flip clamps 303 facing the other flip frame 302, so that when the packaging bag is pushed upward by the air impact, the upwardly moving packaging bag can be limited, thereby facilitating the prevention of excessive upward movement of the packaging bag, which may lead to unstable clamping, thereby facilitating the improvement of the stability of the packaging bag clamping.

[0121] Through the cooperation between the piston 502 and the connecting rod 503, combined with the sliding installation of the edge frame 401, the lower conveying component can flexibly adjust the position of the packaging bag according to the needs of the packaging process, thereby enhancing the versatility and adaptability of the equipment. The multiple air flushing tubes 5 are distributed in a linear array, which can evenly apply airflow to the packaging bag, effectively preventing the packaging bag from being offset or tilted during the adjustment process, and ensuring the accuracy and stability of the adjustment. This design not only improves the stability and reliability of the packaging, but also optimizes the smoothness of the entire packaging process, providing a strong guarantee for high-efficiency automated packaging.

[0122] As an optional embodiment, the upper conveying assembly includes:

[0123] Two second translation frames 7 are respectively installed inside the main frame 1 through second driving members 701 to drive the second translation frames 7 to move horizontally and vertically along the horizontal position;

[0124] Two sets of third clamping ends 702, with multiple third clamping ends 702 forming a group, are installed in a linear array on opposite sides of the two second translation frames 7;

[0125] The second translation frame 7 is driven by the second driving member 701 and can move horizontally and vertically. The third clamping end 702 is installed in a linear array on the opposite side of the second translation frame 7 and works in conjunction with the lower conveying component. When the packaging bag is conveyed, the lower conveying component first conveys the packaging bag to the specified position. At this time, the third clamping end 702 of the upper conveying component clamps the packaging bag, and the second driving member 701 drives the second translation frame 7 to move to realize the continued conveying of the packaging bag. Its clamping method cooperates with the lower conveying component to ensure the stability of the packaging bag during the conveying process. The upper conveying component and the lower conveying component work alternately to realize continuous and smooth material conveying, improve packaging efficiency, ensure that the packaging bag is firmly clamped, prevent deviation or falling during transportation, improve packaging quality, reduce production failure rate, enhance equipment reliability, reduce manual intervention, and reduce labor intensity and production costs.

[0126] As an optional embodiment, the opening unit 103 includes:

[0127] Two connecting frames 6 are slidably mounted on the top of the two second translation frames 7, and are mounted on the side walls of the main frame 1 through telescopic driving members;

[0128] Two sets of second clamping ends 601 are fixed to opposite sides of the two connecting frames 6;

[0129] Two suction cups 602 are respectively mounted on two connecting frames 6 through telescopic drive members and are connected to a negative pressure pump;

[0130] After the packaging bag is transported to the opening unit 103 by the upper conveying assembly, when the second driving member 701 drives the second translation frame 7 to move vertically, the sliding connection between the connecting frame 6 and the second translation frame 7 will not drive the movement of the connecting frame 6. When the second driving member 701 drives the second translation frame 7 to move horizontally, the telescopic driving member cooperates at the same time, so that the connecting frame 6 moves horizontally synchronously, thereby driving the two connecting frames 6 to move relative to each other, so that the second clamping end 601 approaches and clamps the two sides of the packaging bag. At the same time, the two suction cups 602 on the connecting frame 6 approach each other to clamp the packaging bag, and then the negative pressure pump is started to utilize The opening of the packaging bag is sucked by the negative pressure, and then the two corresponding telescopic driving members drive the two suction cups 602 away from each other to drive the opening of the packaging bag to open, preparing for subsequent material filling. Through the cooperation of the connecting frame 6 and the telescopic driving member, the second clamping end 601 can accurately clamp the packaging bag to ensure its stable position during the opening process. The synergistic effect of the suction cup 602 and the negative pressure pump can reliably open the opening of the packaging bag, ensuring that subsequent material filling can be carried out smoothly, improving the overall packaging efficiency and quality, reducing the packaging error rate caused by opening failure, and enhancing the reliability and automation of the equipment.

[0131] As an optional embodiment, the opening unit 103 further includes:

[0132] The laser light 801 is fixed at the center of one of the suction cups 602;

[0133] The light developing chamber 8 is fixedly connected to the middle part of the connecting pipe of another suction cup 602;

[0134] The reflector 802 is installed inside the display chamber 8. When there is no bag blocking the space between the two suction cups 602, the light from the laser lamp 801 enters the display chamber 8 and is reflected by the reflector 802 to illuminate the display chamber 8.

[0135] When the packaging bag enters the opening unit 103, the suction cup 602 tries to absorb and open the opening of the packaging bag under the action of the negative pressure pump. At this time, the laser lamp 801 is located at the center of one of the suction cups 602, and the light display chamber 8 is connected to the middle of the connecting pipe of the other suction cup 602. When there is no packaging bag blocking the two suction cups 602, the light emitted by the laser lamp 801 can smoothly enter the light display chamber 8, and illuminate the light display chamber 8 after being reflected by the reflector 802, thereby forming an optical path detection mechanism for judging whether the packaging bag is correctly clamped. Through this optical detection method, it is possible to quickly and accurately judge whether the packaging bag is correctly clamped. Regular conveying and clamping ensures the accuracy of subsequent material filling. If the light is blocked, it means that the packaging bag is normally clamped between the two sets of second clamping ends 601. If the light is not blocked, it means that there is no packaging bag between the two sets of second clamping ends 601, which means that the packaging bag is not clamped by the second clamping ends 601. In this way, the opening failure can be detected immediately and corresponding processing can be performed, thereby improving the reliability and stability of the entire packaging process. This non-contact detection method will not cause physical damage to the packaging bag, ensures the integrity of the packaging, and responds quickly. It can be seamlessly connected with the automated packaging process to improve overall production efficiency.

[0136] As an optional embodiment, it also includes:

[0137] Two electromagnets 10 are respectively fixed to the bottom of opposite sides of the two first translation frames 4;

[0138] Two magnets 1001 are slidably mounted on the top of opposite sides of the two first translation frames 4;

[0139] Two sets of fourth clamping ends 1002 are respectively installed on opposite sides of the two magnets 1001;

[0140] When the display chamber 8 is illuminated, the electromagnet 10 is energized to generate a magnetic field, which pushes the magnet 1001 slidably installed on the top of the opposite side of the first translation frame 4, so that the magnet 1001 drives the fourth clamping end 1002 to move upward, thereby driving the clamped packaging bag to move upward for lifting, so that when the packaging bag is positioned but not between the two second clamping ends 601, it can push the packaging bag to move upward, thereby pushing the packaging bag to reach between the two second clamping ends 601, which is conducive to the stable clamping and conveying of the packaging bag. Through the interaction between the electromagnet 10 and the magnet 1001, the packaging bag is lifted, the stability of the packaging bag during opening and conveying is improved, and the packaging bag is avoided from being offset or falling off due to unstable clamping, thereby improving the reliability and automation level of the entire packaging equipment.

[0141] As an optional embodiment, the opening unit 103 further includes:

[0142] Two annular rings 9 are respectively installed on the opposite side edges of the two suction cups 602. The annular rings 9 are both provided with a metal frame wrapped with a rubber sleeve;

[0143] Two groups of circular holes 901, one group is formed in an arc array above the edge of one annular ring 9, and the other group is formed in an arc array below the edge of the other annular ring 9;

[0144] Two connecting pipes 902 are connected to the annular rings 9 on the two suction cups 602 respectively, and are arranged up and down opposite to the circular hole 901. The other ends of the two connecting pipes 902 are connected to the air pump to deliver high-temperature and low-temperature airflow respectively;

[0145] During the process of sucking and opening the opening of the packaging bag, when negative pressure adsorption is performed inside the suction cup 602, high-temperature and low-temperature airflows are respectively transported to the interior of the two suction pipes through the two connecting pipes 902, so that the high-temperature and low-temperature airflows flow through the annular ring 9 for a circle and then enter the interior of the suction cup 602 along the circular hole 901, so that the packaging bag meets inside the suction cup 602. When the hot and cold meet, due to the heat conduction effect of the metal frame and the fact that the interior of the transported high-temperature and low-temperature airflows contains some water vapor, the water vapor condenses when the hot and cold meet, so that a small amount of condensed water vapor is generated on the edge of the suction cup 602, making it more stable during the adsorption process of the suction cup 602, which is beneficial to improving the stability when adsorbing the opening of the packaging bag.

[0146] Working principle of the present invention: The single material taking unit 101 is installed on the edge of one end of the main frame 1. It can accurately support and grab a single packaging bag, ensuring that only one packaging bag is taken at a time, providing a stable foundation for subsequent processes. The transfer unit 102 cooperates with the single material taking unit 101 to perform a preliminary transfer operation on the grabbed packaging bag so that it can smoothly enter the next link. The opening unit 103 obtains the packaging bag with the help of the lower conveying component and uses the negative pressure to open the opening of the packaging bag. This process prepares for subsequent material filling. The feeding unit 104, under the alternating conveying action of the lower conveying component and the upper conveying component, accurately conveys the opened packaging bag to the designated position for material packaging. To ensure that the materials can be accurately loaded into the packaging bags, the sealing unit 105 also transports the packaging bags with completed material packing to itself through the alternating transportation of the lower conveying component and the upper conveying component, seals the packaging bags, and completes the entire packaging process, thereby effectively avoiding the packaging bags from falling during the transportation process. Since only one packaging bag is transported at a time, and the stable clamping and orderly transportation of each unit are used to ensure the stability of the packaging bags in each link, thereby greatly improving the stability and reliability of the packaging, improving the overall packaging efficiency and quality, and reducing the production failure rate caused by problems such as bag jamming and bag dropping, making the entire automated bag packaging process smoother and more efficient.
