[0030] Flexible packaging is a form of packaging using flexible materials such as film and paper. Flexible packaging equipment is equipment that uses flexible packaging materials to package products of different shapes and sizes.

[0031] Flexible packaging loading equipment in the related art usually glues the starting end of the new roll to the ending end of the old roll when changing rolls. However, since the machine does not stop during the roll changing process, sufficient margin of the old roll needs to be left to ensure a successful roll change, and then the excess part of the old roll margin is cut off, resulting in a waste of resources.

[0032] Based on this, in order to improve the problems in the related art, the embodiments of the present application provide the following solutions.

[0033] Please also read Figures 1 to 3The embodiment of the present application provides a flexible packaging continuous feeding and non-stop feeding device 100, which includes an installation panel 10, a roll changing component 20, an unwinding component 30 and a connecting component 40. The roll changing component 20 is arranged on the installation panel 10; the roll changing component 20 is used to change the position of the material roll 200; the unwinding component 30 is arranged on the installation panel 10; the unwinding component 30 is located on one side of the roll changing component 20; the outer diameter of the unwinding component 30 can be changed; the unwinding component 30 is used to drive the raw material belt 210 wound on its outer surface to move so as to extract the raw material belt 210 in the material roll 200; the connecting component 40 is arranged on the installation panel 10; the connecting component 40 is located between the roll changing component 20 and the unwinding component 30; the connecting component 40 is used to connect the terminal end of the material roll 200 with the starting end of another material roll 200; wherein, the raw material belt 210 is wound on the unwinding component 30 for at least one circle; the unwinding component 30 can reduce its own outer diameter to reduce the tension of the raw material belt 210 wound on its outer surface, thereby keeping the moving speed of the raw material belt 210 at the output end of the unwinding component 30 unchanged, and the terminal end of the material roll 200 remains stationary at the input end of the unwinding component 30, so as to cooperate with the roll changing component 20 to change the roll and the connecting component 40 to complete the connection.

[0034] It can be understood that the mounting panel 10 is a component for carrying other components, such as a workbench or a metal plate, but not limited thereto. The roll changing component 20 is a component for replacing the exhausted roll 200 with a new roll 200. The roll changing component 20 may include a conveyor belt, through which the new roll 200 is transported and the exhausted roll 200 is transported away, or may include a robot, through which the roll 200 is picked up or placed, but not limited thereto. The unwinding component 30 is a component for extracting the raw material tape 210 from the roll 200 and conveying it to the production line. The outer diameter of the roll changing component 20 can be changed, thereby changing the tension of the raw material tape 210. For example, the roll changing component 20 may include a cylinder with a variable diameter and a driving motor. By winding the raw material tape 210 around the curved surface of the cylinder with a variable diameter, the cylinder is driven by a driving motor to rotate, and the raw material tape 210 is pulled out of the roll 200. The tension of the raw material tape 210 is changed by changing the diameter of the cylinder; or the unwinding component 30 is a component for extracting the raw material tape 210 from the roll 200 and conveying it to the production line. The outer diameter of the roll changing component 20 can be changed, thereby changing the tension of the raw material tape 210. For example, the roll changing component 20 may include a cylinder with a variable diameter and a driving motor. By winding the raw material tape 210 around the curved surface of the cylinder with a variable diameter, the cylinder is driven by a driving motor to rotate, and the raw material tape 210 is pulled out of the roll 200. The tension of the raw material tape 210 is changed by changing the diameter of the cylinder; or The assembly 30 may include a disk, a plurality of long rods and a driving motor. The plurality of long rods are spaced and evenly arranged along the circumferential direction of the axis of the disk. The long rods can move in a direction perpendicular to the axis of the disk. The raw material tape 210 is wound around the outer side of the plurality of long rods away from the axis. The long rods are moved toward the axis of the disk to reduce the diameter of the wound raw material tape 210, thereby changing the tension of the raw material tape 210 on the unwinding assembly 30. The disk is driven to rotate by the driving motor to pull the raw material tape 210 out of the material roll 200, but the invention is not limited thereto. The connecting assembly 40 is a component used to connect the terminal end of the exhausted material roll 200 with the starting end of the new material roll. The connecting assembly 40 can connect the two material rolls 200 by hot pressing or by bonding, but the invention is not limited thereto.

[0035] As can be seen from the above, the flexible packaging continuous feeding and non-stop loading equipment 100 provided in the embodiment of the present application pulls the raw material belt 210 out from the material roll 200 on the roll changing component 20 through the unwinding component 30. When the roll needs to be changed, the outer diameter of the unwinding component 30 is reduced, and the tension of the raw material belt 210 on the unwinding component 30 is reduced. At this time, the output speed of the raw material belt 210 at the output end of the unwinding component 30 remains unchanged, and the diameter of the raw material belt 210 wound on the unwinding component 30 gradually decreases. The raw material belt 210 at the input end of the unwinding component 30 remains stationary, so that the terminal end of the material roll 200 stops at a preset position, and the roll changing component 20 is controlled to move the new material roll 200 to the input end of the unwinding component 30, and the starting end of the new material roll 200 is connected to the terminal end of the exhausted material roll 200 through the connecting component 40 to complete the non-stop feeding, and gradually restore the outer diameter of the unwinding component 30 to the initial size, waiting for the next roll change. In this way, by adjusting the outer diameter of the unwinding assembly 30 and reducing the tension of the raw material belt 210 on the unwinding assembly 30, the terminal end of the old material roll 200 can remain stationary for a period of time, giving sufficient time for roll replacement and continuation, which is conducive to ensuring production continuity, improving production efficiency, ensuring product quality, reducing raw material loss, and thus reducing production costs.

[0036] In some embodiments, please refer to Figures 1 to 3 The mounting panel 10 has a mounting plane 101; the roll changing assembly 20 has a roll-out position 201 and at least one standby position 202; the roll changing assembly 20 includes a roll changing disc 203 and a plurality of roll racks 204, the roll changing disc 203 is rotatably arranged on the mounting panel 10 around its own axis; the axis of the roll changing disc 203 is perpendicular to the mounting plane 101; the plurality of roll racks 204 are evenly and spacedly arranged on the roll changing disc 203 around the circumference of the roll changing disc 203; the roll racks 204 can rotate around their own axes; the axis of the roll racks 204 is perpendicular to the mounting plane 101; one of the plurality of roll racks 204 is located at the roll-out position 201, and the remaining roll racks 204 are located at the standby position 202 one by one; wherein the roll changing disc 203 is used to rotate to change the position of the roll racks 204, so that the material roll 200 located at the standby position 202 replaces the material roll 200 located at the roll-out position 201.

[0037] It can be understood that the roll changing assembly 20 can move the material roll 200 to change the position of the material roll 200. The unwinding position 201 is used to place the material roll 200 that outputs the raw material tape 210 to the unwinding assembly 30, and the standby position 202 is used to store the material roll 200 to be replaced. The material roll 200 in the standby position 202 can be replaced manually or by a robot device, but it is not limited to this. The roll changing disk 203 is a component used to rotate to change the position of the material roll 200. The roll changing disk 203 can include a disk body and a drive motor. The disk body can be rotatably arranged on the installation panel 10 around its own axis. The drive motor is arranged on the disk body. The power output end of the drive motor is connected to the disk body. The disk body can be a circular disk body or a square disk body, but it is not limited to this. The roll rack 204 is a component used to place the material roll 200. The roll rack 204 can be connected to the roll changing disk 203 through a bearing so that the roll rack 204 can rotate around its own axis.

[0038] In this way, by arranging multiple roll racks 204 rotatably around their own axes on the roll changing disk 203, the material roll 200 can rotate around its own axis, and the multiple roll racks 204 are evenly and spaced apart around the circumference of the roll changing disk 203, and the roll changing disk 203 is rotatably arranged on the mounting panel 10 around its own axis, so that the roll changing disk 203 can quickly move the material roll 200 to the preset unloading position 201, which is conducive to smooth unloading of the material roll 200, improving the stability of the flexible packaging continuous feeding and non-stop loading equipment 100, avoiding production pauses, reducing the losses caused by impacts on the flexible packaging continuous feeding and non-stop loading equipment 100, and effectively improving production efficiency.

[0039] Optionally, in some embodiments, see Figures 1 to 3 The unwinding assembly 30 includes a drawing member 301 and a reducing portion 302. The drawing member 301 can be rotatably arranged on the installation panel 10 around its own axis; the axis of the drawing member 301 forms an angle with the installation plane 101; one end of the reducing portion 302 is arranged at the end of the drawing member 301 away from the installation panel 10; the diameter of the outer wall of the reducing portion 302 can be reduced; the axis of the reducing portion 302 is colinear with the axis of the drawing member 301; the maximum diameter of the reducing portion 302 is equal to the diameter of the drawing member 301.

[0040] It can be understood that the drawing member 301 is a member used to rotate to draw the raw material tape 210 from the material roll 200. The drawing member 301 can be a rotating cylinder, and the friction between the surface of the rotating cylinder and the raw material tape 210 is increased by covering the surface of the rotating cylinder with silica gel or providing fine grooves on the surface of the rotating cylinder, but it is not limited to this. The angle between the axis of the drawing member 301 and the mounting plane 101 is less than 90°, so that the raw material tape 210 gradually moves away from the mounting panel 10 as the drawing member 301 rotates, and the raw material tape 210 will not overlap on the drawing member 301. The variable diameter portion 302 is a member used to change the winding diameter of the raw material tape 210 to adjust the tension of the raw material tape 210. For example, a cylinder that can change the diameter can be used, or a plurality of movable rods can be used to change the diameter of the variable diameter portion 302 formed by the plurality of rods, but it is not limited to this.

[0041] With such arrangement, the raw material tape 210 is drawn out from the material roll 200 by the withdrawal member 301, and the raw material tape 210 is gradually moved away from the installation panel 10 while being wound on the withdrawal member 301 and the diameter-changing portion 302, so as to avoid the raw material tape 210 overlapping on the withdrawal member 301 and the diameter-changing portion 302. When the roll needs to be changed, the diameter of the diameter-changing portion 302 is controlled to reduce so as to reduce the tension on the raw material tape 210, thereby making the moving speed of the raw material tape 210 at the output end of the diameter-changing portion 302 unchanged, while the raw material tape 210 at the input end of the withdrawal member 301 stops moving, which is conducive to ensuring the stable loading of the flexible packaging material, thereby ensuring the continuity and stability of production, reducing the difficulty and danger of high-speed roll changing, reducing the waste of raw materials, and improving production efficiency and quality.

[0042] In some embodiments, see Figures 1 to 3 The reducing portion 302 includes a plurality of reducing rods 3021, one end of which is evenly arranged around the circumference of the roll-drawing member 301 at an end of the roll-drawing member 301 away from the mounting panel 10; the reducing rods 3021 can move in a direction perpendicular to the axis of the roll-drawing member 301; the plurality of reducing rods 3021 are spaced apart; the distances from the plurality of reducing rods 3021 to the axis of the roll-drawing member 301 are the same; the axis of the reducing rod 3021 is parallel to the axis of the roll-drawing member 301.

[0043] It can be understood that the diameter-changing rod 3021 is a component used to support the raw material roll 200 and change its position to adjust the winding diameter of the raw material roll 200. The diameter-changing rod 3021 can be a round rod or a rod body with a curved surface on the side away from the roll-drawing member 301, but is not limited thereto. A guide rail and an electric trolley can be set at the end of the roll-drawing member 301 away from the installation panel 10. The guide rail is along the circumference of the end surface of the end of the roll-drawing member 301 away from the installation panel 10 toward the center of the end surface of the end of the roll-drawing member 301 away from the installation panel 10. The electric trolley can move along the radius direction of the end surface of the end of the roll-drawing member away from the installation panel 10. One end of the diameter-changing rod 3021 is set on the electric trolley so that the diameter-changing rod 3021 can move in a direction perpendicular to the axis of the roll-drawing member 301. The distances between the multiple diameter-changing rods 3021 and the axis of the drawing member 301 are the same, so that when the stock tape 210 is wound around the diameter-changing rods 3021 on the side away from the axis of the drawing member 301, the distances between each point on the stock tape 210 and the axis of the drawing member 301 are the same. The axis of the diameter-changing rods 3021 is parallel to the axis of the drawing member 301, so that the stock tape 210 can be gradually away from the installation panel 10 while being wound around the diameter-changing rods 3021 as the drawing member 301 rotates.

[0044] In this way, by setting up multiple reducing rods 3021 that can move in a direction perpendicular to the axis of the drawing member 301, and the multiple reducing rods 3021 are spaced apart, the distances between the multiple reducing rods 3021 and the axis of the drawing member 301 are the same, and the axis of the reducing rod 3021 is parallel to the axis of the drawing member 301, so that the raw material belt 210 can be wound around the reducing rod 3021 as the drawing member 301 rotates, and gradually moves away from the installation panel 10. When the reducing rod 3021 moves toward the axis of the drawing member 301, the raw material belt 210 will not overlap and entangle, which effectively enables the raw material belt 210 to be smoothly transmitted at all times, thereby improving the stability of the flexible packaging continuous feeding and non-stop loading equipment 100, avoiding production pauses, reducing production losses, and being conducive to improving production efficiency and quality.

[0045] In some embodiments, see Figure 2 and Figure 3 The reducing rod 3021 includes a straight rod body 30211 and a plurality of transfer wheels 30212, one end of the straight rod body 30211 is movably arranged on one end of the rolling element 301 along a direction perpendicular to the axis of the rolling element 301; the axis of the straight rod body 30211 is parallel to the axis of the rolling element 301; the plurality of transfer wheels 30212 are arranged on the straight rod body 30211 along the axis direction of the straight rod body 30211; the transfer wheel 30212 can rotate around its own axis.

[0046] It can be understood that the straight rod body 30211 is a component used to support the transfer wheel 30212 and further support the raw material belt 210. The straight rod body 30211 can be a round rod or a square rod, but is not limited thereto. The transfer wheel 30212 is a component used to reduce the resistance of the raw material belt 210 moving on the variable diameter rod 3021. The diameter of the transfer wheel 30212 is larger than the diameter of the straight rod body 30211, so that the outer side of the transfer wheel 30212 protrudes from the outer side of the straight rod body 30211. The transfer wheel 30212 can be sleeved on the straight rod body 30211, and the inner side of the transfer wheel 30212 and the outer side of the straight rod body 30211 slide and rub; or the bearing can be sleeved on the straight rod body 30211, and the transfer wheel 30212 can be sleeved on the bearing, and rolling friction is performed through the ball of the bearing, but is not limited thereto.

[0047] In this way, multiple transfer wheels 30212 are set on the straight rod body 30211, and the raw material belt 210 is wrapped around the outer surface of the transfer wheel 30212. The transfer wheel 30212 rotates, thereby reducing the resistance encountered by the raw material belt 210 when moving on the variable diameter portion 302, improving the transmission efficiency, and avoiding the breakage of the raw material belt 210 during transmission, reducing the loss in the production process, improving the stability of the flexible packaging continuous feeding and non-stop loading equipment 100, reducing the wear and tear of the flexible packaging continuous feeding and non-stop loading equipment 100, extending the service life, and reducing the maintenance cost.

[0048] Optionally, the variable diameter portion 302 includes a plurality of telescopic arc-shaped pieces, the telescopic arc-shaped pieces include a main shell and a telescopic portion, one end of the main shell is arranged on the end surface of one end of the rolling element 301 along the circumference of the end surface of one end of the rolling element 301; the main shell can move in a direction perpendicular to the axis of the rolling element 301; the length direction of the main shell is parallel to the axial direction of the rolling element 301; the side of the main shell away from the axial direction of the rolling element 301 is an arc surface; the main shell has an arc-shaped space; the axis of the arc-shaped space is colinear with the axis of the rolling element 301; the telescopic portion can be rotatably arranged in the arc-shaped space along the circumferential direction of the main shell.

[0049] It can be understood that the multiple telescopic arc-shaped pieces are arranged along the circumference of the end surface of one end of the withdrawal member 301 and can together form the side of a cylinder so that the raw material belt 210 can be wound around the side of the diameter-changing portion 302 .

[0050] In this arrangement, by moving the main shell body in a direction perpendicular to the axis of the withdrawal member 301, the telescopic portion is compressed into the arc space to reduce the diameter of the variable diameter portion 302, thereby reducing the tension of the raw material belt 210 wound on the variable diameter portion 302, so that the moving speed of the raw material belt 210 located at the output end of the variable diameter portion 302 remains unchanged, while the raw material belt 210 located at the input end of the withdrawal member 301 stops moving, which is beneficial to ensure the stable loading of the flexible packaging material, thereby ensuring the continuity and stability of production, reducing the difficulty and danger of high-speed roll changing, reducing raw material waste, and improving production efficiency and quality.

[0051] Optionally, in some embodiments, see Figures 1 to 3 The connecting component 40 includes a guide member 401 and a connecting member 402. The guide member 401 is arranged on the installation panel 10. One end of the guide member 401 is connected to the output end of the roll changing component 20, and the other end of the guide member 401 is connected to the input end of the roll drawing member 301. The guide member 401 has a connecting plane 4011. The connecting member 402 is movably arranged on the installation panel 10 along a length direction parallel to the guide member 401. The connecting member 402 is located above the guide member 401.

[0052] It can be understood that the guide member 401 is a component used to carry the raw material tape 210 and guide the raw material tape 210 to move from the output end of the roll changing assembly 20 to the input end of the unwinding assembly 30. One end of the guide member 401 can be connected to the output end of the roll rack 204 located at the roll-out position 201 in the roll changing assembly 20. When the roll needs to be changed, the guide member 401 can provide a plane to carry the terminal end of the old roll 200 and the starting end of the new roll. The guide member 401 can be a long plate or a guide rail, but is not limited to this. The connecting member 402 is a component used to connect the terminal end of the old roll 200 with the starting end of the new roll. The connecting member 402 can be connected by applying glue on the connection to connect the terminal end of the old roll 200 with the starting end of the new roll, or by hot pressing the connection to connect the terminal end of the old roll 200 with the starting end of the new roll, but is not limited to this.

[0053] In this way, the output end of the roll changing assembly 20 and the input end of the roll drawing member 301 are connected through the guide member 401, so that the raw material belt 210 can move along the connecting plane 4011 of the guide member 401, and the connecting member 402 is arranged above the guide member 401. When changing the roll, the terminal end of the old material roll 200 on the connecting plane 4011 is connected to the starting end of the new material roll through the connecting member 402, which is conducive to keeping the raw material belt 210 stable during the unwinding and changing processes, improving the stability of the flexible packaging continuous feeding and non-stop loading equipment 100, eliminating the need for manual roll changing and connection, improving the flatness and strength of the connection when changing the roll, reducing the downtime caused by roll changing, and thus improving the overall production efficiency.

[0054] Optionally, see Figures 1 to 3 The connecting part 402 includes a moving part 4021, a picking part 4022 and a connecting part 4023. The moving part 4021 is movably arranged on the installation panel 10 along the length direction parallel to the guide part 401; the picking part 4022 is arranged on the side of the moving part 4021 facing the guide part 401; the picking part 4022 is used to pick up the starting end of the material roll 200; the connecting part 4023 is arranged on the side of the moving part 4021 facing the guide part 401; the connecting part 4023 is located on the side of the picking part 4022 close to the roll changing component; the connecting part 4023 is used to connect the terminal end of the old material roll 200 with the starting end of the newly unwound material roll 200.

[0055] It can be understood that the moving part 4021 is a component that can move on the installation panel 10 along the length direction parallel to the guide member 401. For example, the moving part 4021 can be an electric trolley, and a motorized roller is provided on one side of the electric trolley. A groove can be provided on the installation panel 10 along the length direction parallel to the guide member 401, and the electric trolley is provided in the groove. The motorized roller abuts against the inner wall of the groove, and the motorized roller is driven to enable the moving part 4021 to move in the groove; or the moving part 4021 can be a slide, and a guide rail and a lead screw can be provided on the installation panel 10 along the length direction parallel to the guide member 401. A nut is provided on one side of the slide, and the nut can cooperate with the lead screw, and the lead screw is driven to move by a motor, so that the nut and the slide move along the length direction of the lead screw, but it is not limited thereto. The picking part 4022 is a component for picking up the starting end of the material roll 200. For example, the picking part 4022 can use a manipulator or a suction cup device, but it is not limited thereto. The connecting part 4023 is a component used to connect the terminal end of the old material roll 200 with the starting end of the newly unrolled material roll 200. For example, the connecting part 4023 can adopt a nozzle to connect the terminal end of the old material roll 200 with the starting end of the newly unrolled material roll 200 by spraying glue on the raw material belt 210; or the connecting part 4023 can adopt a hot pressing plate to heat the hot pressing plate to hot-press the terminal end of the old material roll 200 with the starting end of the newly unrolled material roll 200, but it is not limited to this.

[0056] With such arrangement, the moving part 4021 moves on the installation panel 10 along the length direction parallel to the guide member 401, driving the picking part 4022 and the connecting part 4023 to move, so that the starting end and the ending end of the material roll 200 staying at any position on the connecting plane 4011 can be picked up by the picking part 4022 and connected by the connecting part 4023 without manual operation, which is beneficial to improving the accuracy of roll changing and connecting work, ensuring the quality and consistency of the products, and effectively improving the flexibility and adaptability of the flexible packaging continuous feeding and non-stop loading equipment 100, thereby improving production efficiency.

[0057] In some embodiments, see Figures 1 to 3 The flexible packaging continuous feeding and non-stop loading equipment 100 also includes a detection device 50, which is arranged on the connecting component 40; the detection device 50 is used to detect the position of the end of the old material roll 200, and the remaining amount and the starting end position of the material roll 200 at the unwinding position 201.

[0058] It can be understood that the detection device 50 is a component for detecting the position of the terminal end of the old material roll 200, and the position of the remaining amount and the starting end of the material roll 200 located at the unwinding position 201. For example, the detection device 50 can use an infrared ranging sensor to measure the distance from the detection device 50 to the material roll 200 and the distance between the starting end and the terminal end of the material roll 200; or a camera can be used to capture the image of the material roll 200 located at the unwinding position 201 and the image of the raw material tape 210 on the splicing plane 4011 through the camera to obtain the position of the terminal end of the old material roll 200, and the position of the remaining amount and the starting end of the material roll 200 located at the unwinding position 201, but it is not limited to this.

[0059] With such arrangement, the detection device 50 detects the position of the terminal end of the old material roll 200, and the remaining amount and the starting end of the material roll 200 at the unwinding position 201, so as to accurately determine the time when the roll needs to be changed, and then control the roll changing component 20, the unwinding component 30 and the connecting component 40 to execute the corresponding process, thereby improving the accuracy and consistency of the flexible packaging continuous feeding and non-stop loading equipment 100, avoiding material waste due to untimely roll changing, improving material utilization, reducing production costs, and effectively improving production efficiency.

[0060] See also Figure 4 The embodiment of the present application also provides a method for continuously feeding and loading flexible packaging without pauses. The method for continuously feeding and loading flexible packaging provided in the embodiment of the present application can be applied to a flexible packaging continuous feeding and loading device 100. At this time, the flexible packaging continuous feeding and loading device 100 is the executor of the method for continuously feeding and loading flexible packaging provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the flexible packaging continuous feeding and loading device 100.

[0061] For example, see Figure 1The flexible packaging continuous feeding and non-stop loading equipment 100 may include an installation panel 10, a roll changing assembly 20, an unwinding assembly 30, a splicing assembly 40 and a control device 60, wherein the roll changing assembly 20 is arranged on the installation panel 10; the roll changing assembly 20 is used to change the position of the material roll 200; the unwinding assembly 30 is arranged on the installation panel 10; the unwinding assembly 30 is located on one side of the roll changing assembly 20; the outer diameter of the unwinding assembly 30 can be changed; the unwinding assembly 30 is used to drive the raw material belt 210 wound on its outer surface to move so as to extract the raw material belt 210 in the material roll 200; the splicing assembly 40 is arranged on the installation panel 10; the splicing assembly 40 is located between the roll changing assembly 20 and the unwinding assembly 30; the splicing assembly 40 is used to connect the terminal end of the material roll 200 with the starting end of another material roll 200, and the control device 60 is arranged on the installation panel 10, and the control device 60 is electrically connected to the roll changing assembly 20, the unwinding assembly 30 and the splicing assembly 40 respectively. The control device 60 may be a single chip microcomputer, a PLC, a central processing unit, a handheld device with wireless communication function, a computing device or other processing devices connected to a wireless modem.

[0062] In order to better understand the method for continuously feeding and loading flexible packages without pauses provided in the embodiment of the present application, the specific implementation process of the method for continuously feeding and loading flexible packages without pauses provided in the embodiment of the present application is exemplarily introduced below.

[0063] Figure 4 A schematic flow chart of a method for continuously feeding and loading flexible packaging without pauses provided in an embodiment of the present application is shown. The method for continuously feeding and loading flexible packaging without pauses comprises: S100, obtaining the remaining data of the old material roll located at the roll-out position 201 in real time.

[0064] It can be understood that the old material roll is the material roll 200 being unwound at the unwinding position 201, and the remaining data represents the length of the remaining raw material tape 210 on the old material roll. The remaining data can be obtained by weighing the weight of the old material roll or by measuring the diameter of the old material roll, but is not limited to this.

[0065] S200 , when the margin data is equal to the preset margin value, the unwinding assembly 30 is controlled to perform a first operation; wherein the first operation is used to reduce the tension on the raw material tape 210 on the unwinding assembly 30 .

[0066] It can be understood that the preset margin value is the length of the raw material tape 210 remaining on the old material roll after the unwinding assembly 30 performs the first operation, which enables the terminal end of the old material roll to stay on the connecting plane 4011. The preset margin value can be a value calculated by the flexible packaging continuous feeding non-stop feeding device 100 according to the unwinding speed, or a value set manually, but is not limited thereto. The first operation is used to reduce the tension of the raw material tape 210 on the unwinding assembly 30, so that when the raw material tape 210 at the output end of the unwinding assembly 30 maintains the original output speed, the input speed of the raw material tape 210 at the input end of the unwinding assembly 30 is zero.

[0067] As an optional embodiment of the present application, S200, when the remaining amount data is equal to the preset remaining amount value, controlling the unwinding component 30 to perform a first operation, including: S210, when the remaining amount data is equal to the preset remaining amount value, all the straight rods 30211 are controlled to move toward the axis direction of the roll-drawing member 301.

[0068] It can be understood that when the remaining amount data is equal to the preset remaining amount value, it can be determined that the flexible packaging continuous feeding non-stop loading device 100 needs to change the roll. All straight rods 30211 are controlled to move toward the axis direction of the reeling member 301, reducing the diameter of the raw material tape 210 wound on the reeling assembly 30. The speed at which the straight rods 30211 move toward the axis direction of the reeling member 301 is greater than the speed at which the diameter of the raw material tape 210 wound on the unwinding assembly 30 is reduced, so that the raw material tape 210 is spaced apart from some of the straight rods 30211, reducing the tension on the raw material tape 210.

[0069] In this way, by controlling all the straight rod bodies 30211 to move toward the axial direction of the withdrawal member 301, and the speed of the straight rod bodies 30211 moving toward the axial direction of the withdrawal member 301 is greater than the speed at which the diameter of the stock tape 210 wound on the unwinding component 30 is reduced, the stock tape 210 is spaced apart from some of the straight rod bodies 30211, and the tension on the stock tape 210 is reduced. At this time, the moving speed of the stock tape 210 at the output end of the unwinding component 30 can remain unchanged, while the moving speed of the stock tape 210 at the input end of the unwinding component 30 is zero, until the diameter of the stock tape 210 wound on the unwinding component 30 is reduced to the diameter of the stock tape 210 wound on all the straight rod bodies 30211, so that the tension is restored and the moving speeds of the stock tape 210 at the input and output ends of the unwinding component 30 are the same again.

[0070] S300, controlling the unwinding assembly 30 to perform a second operation; wherein the second operation is used to move the terminal end of the old material roll to a preset position.

[0071] It can be understood that the preset position can be any position on the splicing plane 4011, and the splicing process is completed by moving the terminal end of the old material roll to the splicing plane 4011.

[0072] As an optional embodiment of the present application, S300, controlling the unwinding component 30 to perform a second operation includes: S310, when the terminal end of the old material roll moves to the preset position, the roll-drawing member 301 is controlled to stop rotating.

[0073] It can be understood that the withdrawal member 301 rotates to withdraw the raw material tape 210 from the material roll 200. When the terminal end of the old material roll moves to the preset position, the withdrawal member 301 needs to stop rotating, thereby making the terminal end of the old material roll stationary to complete the splicing work.

[0074] With such arrangement, by controlling the rotation and stopping of the roll-drawing member 301, the terminal end of the old material roll is stopped on the splicing plane 4011, so as to accurately control the margin required for splicing, reduce waste generated by splicing, reduce production costs, and improve production efficiency.

[0075] S400, controlling the roll changing assembly 20 to perform a third operation; wherein the third operation is used to move the starting end of the new material roll to a preset position.

[0076] It can be understood that the starting end of the new material roll is moved to a preset position to overlap with the ending end of the old material roll, thereby completing the splicing.

[0077] As an optional embodiment of the present application, S400, controlling the roll changing component 20 to perform a third operation includes: S410 , controlling the roll changing disc 203 to rotate so as to move the plurality of roll racks 204 , thereby moving the new material roll located at the standby position 202 to the unloading position 201 .

[0078] It is understandable that when the terminal end of the old material roll moves to the preset position, there is no raw material tape 210 on the old material roll, and the roll changing disk 203 needs to be rotated to move the new material roll from the standby position 202 to the unwinding position 201.

[0079] S420 , controlling the roll stand 204 located at the roll-out position 201 to rotate so that the starting end of the new material roll faces the input end of the guide member 401 .

[0080] It can be understood that the roll stand 204 at the unwinding position 201 is controlled to rotate to drive the new material roll to rotate, so that the raw material belt 210 of the new material roll is tilted to abut against the splicing plane 4011 and moves along the length direction of the guide member 401.

[0081] With such arrangement, the new material roll replaces the old material roll by rotating the roll changing disk 203, and the new material roll is rotated to move the raw material tape 210 in the new material roll along the length direction of the guide member 401, without the need for manual roll changing, thereby reducing manpower requirements and improving the accuracy and work efficiency of the roll changing process.

[0082] S500, controlling the connecting component 40 to perform the fourth operation; wherein the fourth operation is used to connect the terminal end of the old material roll to the starting end of the new material roll.

[0083] As an optional embodiment of the present application, S500, controlling the connection component 40 to perform a fourth operation, including: S510, controlling the connecting member 402 to move the starting end of the new material roll to a preset position.

[0084] It can be understood that the starting end of the new material roll is picked up by the picking portion 4022 and moved by the moving portion 4021 to move the starting end of the new material roll to a preset position.

[0085] S520, controlling the connecting member 402 to connect the starting end of the new material roll with the ending end of the old material roll.

[0086] It can be understood that by controlling the connecting part 4023 to connect the starting end of the new material roll with the terminal end of the old material roll, glue can be sprayed on the starting end of the new material roll or the terminal end of the old material roll, or the starting end of the new material roll and the terminal end of the old material roll can be connected together by hot pressing, but it is not limited to this.

[0087] In this arrangement, the starting end of the new material roll is picked up by the picking part 4022, the moving part 4021 is controlled to move to move the starting end of the new material roll to a preset position, and the starting end of the new material roll is connected to the terminal end of the old material roll by controlling the connecting part 4023, thereby avoiding manual intervention, reducing working errors, and effectively improving the strength and accuracy of the connection, thereby improving the reliability of the flexible packaging continuous feeding and non-stop loading equipment 100.

[0088] S600, when it is determined that the terminal end of the old material roll is connected to the starting end of the new material roll, the unwinding component 30 is controlled to perform the fifth operation; wherein the fifth operation is used to restore the tension of the raw material tape 210 on the unwinding component 30.

[0089] As an optional embodiment of the present application, S600, when it is determined that the terminal end of the old material roll is connected to the starting end of the new material roll, the unwinding component 30 is controlled to perform a fifth operation, including: S610, when it is determined that the terminal end of the old material roll is connected to the starting end of the new material roll, the straight rod body 30211 is controlled to move in a direction away from the axis of the drawing element 301 until the outer side surface of the straight rod body 30211 is tangent to the outer side surface of the drawing element 301.

[0090] It is understood that the connection state between the terminal end of the old material roll and the starting end of the new material roll can be determined by the detection device 50. For example, the detection device 50 can use a camera to collect images of the surface of the adhesive connection to determine whether the adhesive connection is firmly connected; or the detection device 50 can use an infrared temperature sensor to detect the temperature of the surface of the hot press connection through the infrared temperature sensor to determine whether the hot press connection is firmly connected, but it is not limited to this. When the outer side surface of the straight rod body 30211 is first tangent to the outer side surface of the drawing member 301, the diameter of the raw material belt 210 when it is wound around the outer side surfaces of the plurality of straight rod bodies 30211 is equal to the diameter of the drawing member 301.

[0091] With such an arrangement, after the terminal end of the old material roll is connected to the starting end of the new material roll, all the straight rods 30211 are controlled to move for resetting, so that the raw material belt 210 is restored to the initial tension, to ensure the smooth movement of the raw material belt 210 and prepare for the next roll changing process, which is conducive to ensuring production continuity, improving production efficiency, ensuring product quality, reducing raw material loss, and thus reducing production costs.
