Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and in particular to a packaging device and a packaging method. Background Art

[0002] When packaging materials with packaging bags, some packaging tools still rely on manual operation. The packaging bags need to be manually put on the packaging tools before the packaging tools can be packaged. The low degree of automation leads to limited packaging efficiency. Existing packaging tools are usually suitable for specific sizes. For packaging bags of different specifications, different packaging tools need to be replaced, which reduces work efficiency. Summary of the invention

[0003] The object of the present invention is to provide a packaging device and a packaging method, and the technical problem to be solved is to improve the application range of the packaging tool so that it is suitable for packaging bags of different specifications.

[0004] The present invention is achieved through the following technical solutions:

[0005] A first aspect provides a packaging device, comprising:

[0006] A support frame, wherein a slide rail and a control device are arranged on the support frame, a traction structure is arranged in the slide rail, and the traction structure comprises a first traction member and a second traction member, wherein the first traction member is used to clamp the front end of the packaging bag, and the second traction member is used to clamp the rear end of the packaging bag;

[0007] The traction structure is connected to a control device, and the control device is used to control the traction structure to move along the slide rail and adjust the distance between the first traction member and the second traction member to adapt to the size of the packaging bag;

[0008] A flattening structure, which is disposed between the fixed column and the slide rail and connected to the support frame; the flattening structure is used to apply pressure to the packaging bag;

[0009] A material unloading device, the material unloading device is arranged on a support frame, and a material unloading port of the material unloading device is used to be arranged above a feeding port of a packaging bag; the material unloading device is connected to a control device, and the control device is used to control the material unloading of the material unloading device;

[0010] Sealing equipment, the sealing equipment is arranged on the support frame, and the operating end of the sealing equipment is used to be arranged below the feeding port of the packaging bag; the sealing equipment is connected to the control equipment, and the control equipment is used to control the sealing equipment to perform sealing operation on the packaging bag;

[0011] The slide rail passes through the unloading equipment and the sealing equipment.

[0012] The traction structure in the packaging device consists of a first traction member and a second traction member, which are used to clamp the front end and the rear end of the packaging bag respectively. This design allows the device to adapt to packaging bags of different lengths; more importantly, by connecting the control device, the distance between the first traction member and the second traction member can be adjusted according to the size of the packaging bag. This adjustable distance feature enables the device to flexibly respond to the needs of packaging bags of different specifications, thereby expanding its scope of application.

[0013] The flattening structure is arranged between the fixed column and the slide rail and connected to the support frame. Its main function is to apply pressure to the packaging bag to ensure that the packaging bag remains flat during the filling and sealing process. This flattening effect is necessary for packaging bags of different specifications, because no matter how big or small the packaging bag is, it is necessary to keep its shape stable for subsequent sealing operations. Therefore, the flattening structure further enhances the applicability of the packaging device to packaging bags of different specifications.

[0014] The above-mentioned feeding equipment and sealing equipment are connected to the control equipment, which enables the entire packaging process to be intelligently controlled. The control equipment can accurately control the feeding of the feeding equipment according to the size and type of the packaging bag to ensure the accuracy and uniformity of the material filling. At the same time, the sealing equipment can also perform accurate sealing operations according to the size and position of the packaging bag. This intelligent control not only improves the packaging efficiency, but also ensures the packaging quality, making the device more suitable for packaging bags of different specifications.

[0015] The above-mentioned slide rail runs through the unloading device and the sealing device, providing a moving channel for the traction structure. This design enables the traction structure to smoothly pass the unloading and sealing areas with the packaging bags, ensuring the continuity and smoothness of the packaging process. Since the design of the slide rail allows the traction structure to move along it, the device can be adaptively adjusted regardless of how the size of the packaging bag changes, thereby achieving efficient packaging of packaging bags of different specifications.

[0016] In summary, the packaging device significantly improves the applicability of packaging tools through the traction structure with adjustable spacing, the application of the flattening structure, the intelligently controlled unloading and sealing equipment, and the through-design of the slide rail, enabling it to flexibly respond to the packaging needs of packaging bags of different specifications.

[0017] Furthermore, the above-mentioned unloading device is provided with a first sensor, and the above-mentioned first sensor is connected to the control device; the above-mentioned first sensor is used to collect the position information of the packaging bag below the unloading device, and transmit the position information to the control device;

[0018] The control device is used to receive the position information of the packaging bag below the unloading device, and when the position information is consistent with the preset unloading position, the unloading device is turned on.

[0019] The first sensor provided on the above-mentioned unloading equipment is connected to the control device, and is used to collect the position information of the packaging bag below the unloading equipment. The position of the packaging bag below the unloading equipment is monitored in real time by the first sensor to ensure that the material can be accurately filled into the packaging bag; by intelligently sensing the position of the packaging bag, the unloading operation can be controlled more accurately, avoiding problems such as material waste or poor packaging due to inaccurate positioning of the packaging bag.

[0020] When the packaging bag position information collected by the first sensor is consistent with the preset unloading position, the control device will start the unloading device. This precise control method ensures that the material is only unloaded at the correct position and time, greatly improving the accuracy and efficiency of packaging. Whether it is for large or small packaging bags, the device can achieve precise unloading through intelligent control, thereby meeting the packaging needs of packaging bags of different specifications.

[0021] By combining the adjustable spacing traction structure, flattening structure and intelligently controlled unloading and sealing equipment, the packaging device has formed a complete and efficient packaging system; and the addition of the first sensor further enhances the intelligence and automation level of this system. The device can automatically adjust the unloading operation according to different packaging bag specifications and position information, thereby achieving efficient and accurate packaging, which not only expands the scope of application of the device, but also greatly reduces the need for manual intervention and improves packaging efficiency.

[0022] Furthermore, the sealing device is provided with a second sensor, and the second sensor is connected to the control device; the second sensor is used to collect the position information of the packaging bag below the sealing device, and transmit the position information to the control device;

[0023] The control device is used to receive the position information of the packaging bag below the sealing device, and when the position information is consistent with the preset sealing position, the sealing device is turned on.

[0024] The above-mentioned second sensor is responsible for collecting the position information of the packaging bag under the sealing device and transmitting this information to the control device in real time; after receiving this information, the control device will compare it with the preset sealing position. Only when the actual position of the packaging bag is consistent with the preset sealing position, the control device will issue a command to start the sealing device for sealing operation; this precise control method ensures the accuracy and reliability of the sealing operation, and avoids problems such as poor sealing or material leakage due to position deviation.

[0025] Since packaging bags of different specifications vary in size and shape, traditional sealing equipment often has difficulty adapting to such changes. By introducing a second sensor and intelligent control, the packaging device can automatically identify the position of the packaging bag and adjust the operation of the sealing device according to its actual position, which enables the device to easily handle packaging bags of different specifications and achieve efficient and accurate sealing operations.

[0026] Furthermore, the device also includes a conveyor belt, which is arranged below the flattening structure, the feeding device and the sealing device, and is connected to the support frame;

[0027] The conveyor belt moves synchronously with the first traction member; the conveyor belt is used to contact the bottom of the packaging bag.

[0028] The above-mentioned conveyor belt moves synchronously with the first traction member, ensuring the continuity and stability of the packaging bag during the entire packaging process; when the traction structure moves with the packaging bag, the conveyor belt also moves synchronously, so that the bottom of the packaging bag always keeps in contact with the conveyor belt. This design avoids the shaking or deviation of the packaging bag during the movement process, ensuring the accuracy of the packaging operation.

[0029] The conveyor belt contacts the bottom of the bag and can provide some support and protection. During the packaging process, especially during the material filling and sealing stages, the bottom of the bag is susceptible to pressure or friction. The presence of the conveyor belt can reduce these adverse effects, keep the bottom of the bag flat and intact, reduce the pulling of the bag by the weight of the material, ensure the flatness of the bag feed port, and make the unloading and sealing operations more convenient.

[0030] Furthermore, the flattening structure comprises a support rod and a roller;

[0031] The support rod is arranged on the support frame;

[0032] The roller is rotatably connected to the support rod;

[0033] At least two of the above-mentioned rollers are provided, and the side walls of the two rollers close to each other are abutted to form a fitting surface, and the fitting surface is used for fitting the packaging bag.

[0034] The introduction of the above-mentioned roller as the main component of the flattening structure makes the flattening process smoother and more continuous. The rotating connection of the roller ensures that the contact between it and the packaging bag is dynamic and can be flexibly adjusted as the packaging bag moves, thereby achieving effective flattening of packaging bags of different specifications.

[0035] Double roller design: at least two rollers are set, and the side walls of the two rollers are attached to form a fitting surface. This design can ensure that the packaging bag is subjected to uniform and stable pressure when passing through, preventing the packaging bag from wrinkling or deforming during the flattening process.

[0036] A second aspect provides a packaging method, which is applied to the above packaging device;

[0037] The packaging method comprises the following steps:

[0038] S100, after receiving the packaging task, the control device extracts the packaging bag size from the packaging task, and determines the preset interval between the first traction member and the second traction member according to the packaging bag size;

[0039] S200, the control device first controls the first traction member to move a preset interval, and then controls the second traction member to move; the moving speed of the second traction member is greater than the moving speed of the first traction member, shortening the actual interval between the first traction member and the second traction member;

[0040] S300, after the packaging bag moves to the position directly below the unloading device, the first traction member and the second traction member stop moving, and the control device controls the unloading device to perform unloading operation;

[0041] S400, after the material is unloaded, the control device first controls the first traction member to move, and when the actual interval between the first traction member and the second traction member is equal to the preset interval, controls the second traction member to move; the moving speed of the first traction member is equal to the moving speed of the second traction member;

[0042] S500: After the packaging bag is moved to the sealing device, the control device controls the sealing device to perform a sealing operation.

[0043] In step S100, the preset interval between the two traction members is determined according to the size of the packaging bag, thereby ensuring that the device can adapt to packaging bags of different specifications.

[0044] In step S200, the traction structure is ensured to clamp the two ends of the packaging bag steadily and accurately through step-by-step control, thereby avoiding twisting or deformation of the packaging bag during the clamping process. The purpose of shortening the actual interval between the first traction member and the second traction member is to leave a margin for the feed port of the packaging bag, so as to facilitate opening the feed port and allow the material to enter the packaging bag through the feed port. The feed port can be blown open by a fan or other equipment, and the installation position of the fan can be adaptively adjusted according to the usage scenario.

[0045] In step S300, when the packaging bag moves to the bottom of the unloading device, the packaging bag is kept still and the unloading operation is performed, ensuring that the material can be accurately filled into the packaging bag and avoiding problems such as material waste or poor packaging due to position deviation.

[0046] In step S400, the feed port of the packaging bag is first stretched to make the top of the packaging bag flat for easy sealing; the front and rear ends of the packaging bag move at the same speed to ensure the stability of the traction structure and the uniform clamping of the packaging bag.

[0047] Furthermore, the packaging bag position information collected by the first sensor is used to determine whether the packaging bag has moved directly below the unloading device. The specific steps are as follows:

[0048] S310, collecting the position information of the packaging bag below the unloading device through the first sensor to obtain first position information, and transmitting the first position information to the control device;

[0049] S320, the control device is configured with a preset unloading position;

[0050] After receiving the first position information, the control device compares the first position information with the preset material unloading position;

[0051] S321, if the first position information is consistent with the preset unloading position, start the unloading equipment;

[0052] S322: If the first position information is inconsistent with the preset unloading position, the first traction member and the second traction member continue to move.

[0053] The above-mentioned first sensor collects the position information of the packaging bag under the unloading equipment in real time, so that the device can sense the current position of the packaging bag at any time, providing an accurate data basis for subsequent position comparison; by comparing the first position information and the preset unloading position, the preset unloading position is set in advance according to the size of the packaging bag and the structural characteristics of the device, aiming to ensure that the material can be accurately filled into the predetermined position of the packaging bag.

[0054] When the first position information is consistent with the preset unloading position (step S321), the control device will start the unloading device to perform unloading operations. This precise control based on real-time position information avoids problems such as material waste or poor packaging due to position deviation, and improves the accuracy and reliability of packaging; if the first position information is inconsistent with the preset unloading position (step S322), the control device will command the first traction member and the second traction member to continue moving until the packaging bag reaches the correct unloading position. This adaptive adjustment mechanism enables the device to adapt to different situations and ensure the smooth unloading operation.

[0055] Furthermore, the position information of the packaging bag collected by the second sensor is used to determine whether the packaging bag has moved to the sealing device. The specific steps are as follows:

[0056] S510, collecting the position information of the packaging bag below the sealing device through the second sensor to obtain second position information, and transmitting the second position information to the control device;

[0057] S520, the control device is configured with a preset sealing position;

[0058] After receiving the second position information, the control device compares the second position information with the preset sealing position;

[0059] S521, if the second position information is consistent with the preset sealing position, start the sealing device;

[0060] S522: If the second position information is inconsistent with the preset sealing position, the first traction member and the second traction member continue to move.

[0061] By introducing a second sensor and refining the steps of determining the position of the packaging bag, this packaging method further improves the accuracy and efficiency of the sealing operation. The second sensor collects the position information of the packaging bag under the sealing device in real time, ensuring that the device can accurately grasp the specific position of the packaging bag during movement, providing key data for subsequent position comparison.

[0062] By comparing the second position information with the preset sealing position, where the preset sealing position is pre-set based on factors such as the size of the packaging bag, the structure of the sealing equipment, and the sealing requirements, it is intended to ensure that the packaging bag is sealed at the optimal position to obtain the best sealing effect.

[0063] When the second position information is consistent with the preset sealing position (step S521), the control device will issue a command to start the sealing device to perform the sealing operation. This precise control based on real-time position information ensures the accuracy and reliability of the sealing operation, and avoids problems such as poor sealing or material leakage caused by position deviation; if the second position information is inconsistent with the preset sealing position (step S522), the control device will command the first traction member and the second traction member to continue moving until the packaging bag reaches the correct sealing position. This adaptive adjustment mechanism enables the device to flexibly respond to different situations and ensure the smooth progress of the sealing operation.

[0064] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0065] The control device adjusts the distance between the first traction member and the second traction member according to the size of the packaging bag. The first traction member and the second traction member clamp the front end and the rear end of the packaging bag respectively. This adjustable distance feature enables the device to flexibly respond to the needs of packaging bags of different specifications, thereby expanding its scope of application.

[0066] The flattening structure is arranged between the fixed column and the slide rail and connected to the support frame. Its main function is to apply pressure to the packaging bag to ensure that the packaging bag remains flat during the filling and sealing process. This flattening effect is necessary for packaging bags of different specifications, because no matter how big or small the packaging bag is, it is necessary to keep its shape stable for subsequent sealing operations. Therefore, the flattening structure further enhances the applicability of the packaging device to packaging bags of different specifications.

[0067] The above-mentioned feeding equipment and sealing equipment are connected to the control equipment, which enables the entire packaging process to be intelligently controlled. The control equipment can accurately control the feeding of the feeding equipment according to the size and type of the packaging bag to ensure the accuracy and uniformity of the material filling. At the same time, the sealing equipment can also perform accurate sealing operations according to the size and position of the packaging bag. This intelligent control not only improves the packaging efficiency, but also ensures the packaging quality, making the device more suitable for packaging bags of different specifications.

[0068] The above-mentioned slide rail runs through the unloading device and the sealing device, providing a moving channel for the traction structure. This design enables the traction structure to smoothly pass the unloading and sealing areas with the packaging bags, ensuring the continuity and smoothness of the packaging process. Since the design of the slide rail allows the traction structure to move along it, the device can be adaptively adjusted regardless of how the size of the packaging bag changes, thereby achieving efficient packaging of packaging bags of different specifications.

[0091] Example 2

[0092] On the basis of Example 1, a first sensor is provided on the unloading device 30, and the first sensor is connected to the control device; the first sensor is used to collect the position information of the packaging bag under the unloading device 30, and transmit the position information to the control device;

[0093] The control device is used to receive the position information of the packaging bag below the unloading device 30, and when the position information is consistent with the preset unloading position, the unloading device 30 is turned on.

[0094] The first sensor provided on the above-mentioned unloading equipment 30 is connected to the control device, and is used to collect the position information of the packaging bag below the unloading equipment 30. The position of the packaging bag below the unloading equipment 30 is monitored in real time by the first sensor to ensure that the material can be accurately filled into the packaging bag; by intelligently sensing the position of the packaging bag, the unloading operation can be controlled more accurately, avoiding problems such as material waste or poor packaging due to inaccurate positioning of the packaging bag.

[0095] When the packaging bag position information collected by the above-mentioned first sensor is consistent with the preset unloading position, the control device will start the unloading device 30. This precise control method ensures that the material is only unloaded at the correct position and time, greatly improving the accuracy and efficiency of packaging; whether it is for large or small packaging bags, the device can achieve precise unloading through intelligent control, thereby meeting the packaging needs of packaging bags of different specifications.

[0096] By combining the adjustable spacing traction structure 50, the flattening structure 20 and the intelligently controlled unloading and sealing device 40, the packaging device has formed a complete and efficient packaging system; and the addition of the first sensor further enhances the intelligence and automation level of the system. The device can automatically adjust the unloading operation according to different packaging bag specifications and position information, thereby achieving efficient and accurate packaging, which not only improves the application scope of the device, but also greatly reduces the need for manual intervention and improves packaging efficiency.

[0097] A fan and a structure for clamping the middle of the packaging bag can be arranged beside the unloading device 30, and the structure opens and tightens the feed port. The fan is used to blow the feed port open, and then the feed port is opened by the opened and tightened structure to facilitate the unloading operation; the fan and the structure are both existing equipment, and the installation positions of the fan and the structure can be adaptively adjusted according to the usage scenario.

[0098] Example 3

[0099] On the basis of any of the above embodiments, a second sensor is provided on the sealing device 40, and the second sensor is connected to the control device; the second sensor is used to collect the position information of the packaging bag under the sealing device 40, and transmit the position information to the control device;

[0100] The control device is used to receive the position information of the packaging bag below the sealing device 40, and start the sealing device 40 when the position information is consistent with the preset sealing position.

[0101] By adding a second sensor to the sealing device 40 and connecting it to the control device, the packaging device has achieved further improvement in intelligent control.

[0102] The above-mentioned second sensor is responsible for collecting the position information of the packaging bag under the sealing device 40 and transmitting this information to the control device in real time; after receiving this information, the control device will compare it with the preset sealing position. Only when the actual position of the packaging bag is consistent with the preset sealing position, the control device will issue an instruction to start the sealing device 40 for sealing operation; this precise control method ensures the accuracy and reliability of the sealing operation, and avoids problems such as poor sealing or material leakage due to position deviation.

[0103] Since packaging bags of different specifications have differences in size and shape, traditional sealing devices 40 often have difficulty adapting to such changes. By introducing a second sensor and intelligent control, the packaging device can automatically identify the position of the packaging bag and adjust the operation of the sealing device 40 according to its actual position, which enables the device to easily handle packaging bags of different specifications and achieve efficient and accurate sealing operations.

[0104] Example 4

[0105] On the basis of any of the above embodiments, the device further comprises a conveyor belt 80, which is arranged below the flattening structure 20, the unloading device 30 and the sealing device 40, and is connected to the support frame 10;

[0106] The conveyor belt 80 moves synchronously with the first traction member 51; the conveyor belt 80 is used to contact the bottom of the packaging bag.

[0107] The conveyor belt 80 moves synchronously with the first traction member 51, ensuring the continuity and stability of the packaging bag during the entire packaging process; when the traction structure 50 moves with the packaging bag, the conveyor belt 80 also moves synchronously, so that the bottom of the packaging bag always keeps in contact with the conveyor belt 80. This design avoids shaking or deviation of the packaging bag during movement, ensuring the accuracy of the packaging operation.

[0108] The conveyor belt 80 is in contact with the bottom of the packaging bag and can play a certain supporting and protective role. During the packaging process, especially during the material filling and sealing stages, the bottom of the packaging bag is easily subjected to pressure or friction. The existence of the conveyor belt 80 can reduce these adverse effects, keep the bottom of the packaging bag flat and intact, reduce the pulling of the packaging bag by the weight of the material, ensure the flatness of the feeding port of the packaging bag, and make the unloading and sealing operations more convenient.

[0109] The width and length of the conveyor belt 80 can also be adjusted as needed to accommodate packaging bags of different specifications. This means that whether it is a large or small size packaging bag, stable transmission can be achieved by adjusting the parameters of the conveyor belt 80. This flexibility enables the device to be applicable to a wider range of packaging needs, increasing its scope of application. The continuous movement of the conveyor belt 80 can drive the packaging bags to quickly pass through each packaging link, thereby improving packaging efficiency. Compared with traditional manual or intermittent packaging methods, the introduction of the conveyor belt 80 greatly reduces the time waste and labor costs in the packaging process.

[0110] Example 5

[0111] Combination Figure 2 , based on any of the above embodiments, the flattening structure 20 includes a support rod 21 and a roller 22;

[0112] The support rod 21 is disposed on the support frame 10;

[0113] The roller 22 is rotatably connected to the support rod 21;

[0114] At least two rollers 22 are provided, and the adjacent side walls of the two rollers 22 are in contact with each other to form a contact surface, and the contact surface is used for contacting the packaging bag.

[0115] The roller 22 is introduced as the main component of the flattening structure 20, so that the flattening process is smoother and more continuous. The rotation connection of the roller 22 ensures that the contact between it and the packaging bag is dynamic and can be flexibly adjusted with the movement of the packaging bag, thereby achieving effective flattening of packaging bags of different specifications.

[0116] Double roller 22 design: at least two rollers 22 are provided, and the side walls of the two rollers 22 are attached to form a fitting surface. This design can ensure that the packaging bag is subjected to uniform and stable pressure when passing through, and prevent the packaging bag from wrinkling or deforming during the flattening process. At the same time, the double rollers 22 can be set as a structure with adjustable spacing. The specific structure can adopt an existing adjustment device, so that the fitting surface of the double rollers 22 can adjust the spacing as needed to adapt to packaging bags of different thicknesses, thereby enhancing the applicability of the device.

[0117] Due to the rotation characteristics and adjustable spacing design of the roller 22, the flattening structure 20 can easily handle packaging bags of different sizes and thicknesses; whether large or small, thick or thin, the roller 22 can provide appropriate pressure to ensure that the packaging bag remains flat after flattening.

[0118] Example 6

[0119] This embodiment 6 provides a packaging method, which is applied to the above packaging device;

[0120] The packaging method comprises the following steps:

[0121] S100, after receiving the packaging task, the control device extracts the packaging bag size from the packaging task, and determines the preset interval between the first traction member 51 and the second traction member 52 according to the packaging bag size;

[0122] S200, the control device first controls the first traction member 51 to move a preset interval, and then controls the second traction member 52 to move; the moving speed of the second traction member 52 is greater than the moving speed of the first traction member 51, and the actual interval between the first traction member 51 and the second traction member 52 is shortened;

[0123] S300, after the packaging bag moves to the position directly below the unloading device 30, the first traction member 51 and the second traction member 52 stop moving, and the control device controls the unloading device 30 to perform unloading operation;

[0124] S400, after the material is unloaded, the control device first controls the first traction member 51 to move, and when the actual interval between the first traction member 51 and the second traction member 52 is equal to the preset interval, the second traction member 52 is controlled to move; the moving speed of the first traction member 51 is equal to the moving speed of the second traction member 52;

[0125] S500: After the packaging bag is moved to the sealing device 40, the control device controls the sealing device 40 to perform a sealing operation.

[0126] This packaging method is closely combined with the above-mentioned packaging device to form a set of efficient and accurate packaging solutions.

[0127] In step S100, the preset interval between the two traction members is determined according to the size of the packaging bag, thereby ensuring that the device can adapt to packaging bags of different specifications.

[0128] In step S200, the traction structure 50 is ensured to be able to clamp the two ends of the packaging bag steadily and accurately through step-by-step control, thereby avoiding possible twisting or deformation of the packaging bag during the clamping process. The purpose of shortening the actual interval between the first traction member 51 and the second traction member 52 is to leave a margin for the feed port of the packaging bag, thereby facilitating the opening of the feed port so that the material can enter the packaging bag through the feed port.

[0129] In step S300, when the packaging bag moves to the bottom of the unloading device 30, the packaging bag is kept still and the unloading operation is performed, ensuring that the material can be accurately filled into the packaging bag and avoiding problems such as material waste or poor packaging due to position deviation.

[0130] In step S400, the feed port of the packaging bag is first stretched to make the top of the packaging bag flat for easy sealing; the front and rear ends of the packaging bag move at the same speed to ensure the stability of the traction structure 50 and the uniform clamping of the packaging bag.

[0131] In a specific embodiment, the packaging bag position information collected by the first sensor is used to determine whether the packaging bag has moved directly below the unloading device 30. The specific steps are as follows:

[0132] S310, collecting the position information of the packaging bag below the unloading device 30 through the first sensor to obtain first position information, and transmitting the first position information to the control device;

[0133] S320, the control device is configured with a preset unloading position;

[0134] After receiving the first position information, the control device compares the first position information with the preset material unloading position;

[0135] S321, if the first position information is consistent with the preset unloading position, start the unloading device 30;

[0136] S322: If the first position information is inconsistent with the preset unloading position, the first traction member 51 and the second traction member 52 continue to move.

[0137] The above-mentioned first sensor collects the position information of the packaging bag under the unloading equipment 30 in real time, so that the device can sense the current position of the packaging bag at any time, providing an accurate data basis for subsequent position comparison; by comparing the first position information and the preset unloading position, the preset unloading position is set in advance according to the size of the packaging bag and the structural characteristics of the device, aiming to ensure that the material can be accurately filled into the predetermined position of the packaging bag.

[0138] When the first position information is consistent with the preset unloading position (step S321), the control device will start the unloading device 30 to perform unloading operations. This precise control based on real-time position information avoids problems such as material waste or poor packaging due to position deviation, and improves the accuracy and reliability of packaging; if the first position information is inconsistent with the preset unloading position (step S322), the control device will command the first traction member 51 and the second traction member 52 to continue moving until the packaging bag reaches the correct unloading position. This adaptive adjustment mechanism enables the device to adapt to different situations and ensure the smooth unloading operation.

[0139] In a specific embodiment, the position information of the packaging bag collected by the second sensor is used to determine whether the packaging bag has moved to the sealing device 40. The specific steps are as follows:

[0140] S510, collecting the position information of the packaging bag below the sealing device 40 through the second sensor to obtain second position information, and transmitting the second position information to the control device;

[0141] S520, the control device is configured with a preset sealing position;

[0142] After receiving the second position information, the control device compares the second position information with the preset sealing position;

[0143] S521, if the second position information is consistent with the preset sealing position, start the sealing device 40;

[0144] S522: If the second position information is inconsistent with the preset sealing position, the first traction member 51 and the second traction member 52 continue to move.

[0145] By introducing the second sensor and refining the steps of determining the position of the packaging bag, the packaging method further improves the accuracy and efficiency of the sealing operation. The second sensor collects the position information of the packaging bag under the sealing device 40 in real time, ensuring that the device can accurately grasp the specific position of the packaging bag during the movement process, providing key data for subsequent position comparison.

[0146] By comparing the second position information with the preset sealing position, where the preset sealing position is pre-set based on factors such as the size of the packaging bag, the structure of the sealing device 40 and the sealing requirements, it is intended to ensure that the packaging bag is sealed at the optimal position to obtain the best sealing effect.

[0147] When the second position information is consistent with the preset sealing position (step S521), the control device will issue a command to start the sealing device 40 to perform the sealing operation. This precise control based on real-time position information ensures the accuracy and reliability of the sealing operation, and avoids problems such as poor sealing or material leakage caused by position deviation; if the second position information is inconsistent with the preset sealing position (step S522), the control device will command the first traction member 51 and the second traction member 52 to continue moving until the packaging bag reaches the correct sealing position. This adaptive adjustment mechanism enables the device to flexibly respond to different situations and ensure the smooth progress of the sealing operation.

It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention.
