Description

Technical Field

[0001] The utility model relates to the technical field of workpiece packaging, in particular to a packaging auxiliary tool and a packaging device. Background Art

[0002] During the packaging process on an air conditioner production line, it's crucial to ensure that the packaging bag is accurately placed on the outside of the corresponding product to protect it. For example, this requires packaging and protecting the air conditioner's outer casing. Fitting and effective packaging is crucial for product transportation and storage.

[0003] However, due to differences in the material and size of packaging bags, as well as limitations in the manual packaging process, the packaging bags and products often fail to fit completely together. Direct packaging without fully fitting the bags will not only affect the aesthetics of the product packaging, but also reduce the sealing effect of the packaging bags.

[0004] In the prior art, after the packaging bag is put on the product and before the packaging bag is sealed with a tape, it is necessary to manually adjust the fit between the packaging bag and the product, or manually adjust the position of the packaging bag, which increases the adjustment time of the packaging process and causes a waste of labor resources.

[0005] Therefore, it is necessary to find an automated packaging auxiliary tooling that can make the packaging bag and the product fit closely. Utility Model Content

[0006] In order to overcome the problems existing in the related technology, one of the purposes of the present utility model is to provide a packaging auxiliary tooling, which can make the packaging bag fit completely with the workpiece by blowing and guiding the packaging bag, thereby improving the sealing and aesthetics of the workpiece packaging, avoiding manual position adjustment during the packaging process, and improving the level of packaging automation.

[0007] A packaging auxiliary tool is provided at the discharge port of the packaging tool, and is used to put the packaging bag on the outside of the workpiece;

[0008] The packaging auxiliary tooling includes a fan assembly and a guide assembly, the guide assembly includes M guide holes, and the M guide holes are all connected to the air outlet of the fan assembly; and the M guide holes can blow air toward the packaging bag outside the workpiece; M is an integer greater than 1.

[0009] In a preferred technical solution of the present invention, a control component is further included, which is electrically connected to the fan assembly and is used to control the air output intensity of the fan assembly.

[0010] The air output intensity can be determined based on the size of the packaging bag and the workpiece. If both the packaging bag and the workpiece are large, such as an air conditioner housing, the larger the size of the workpiece, the larger the corresponding packaging bag. In this case, the air output intensity needs to be increased to ensure a good fit between the workpiece and the packaging bag. For example, when using smaller parts as workpieces, a lower air output intensity is required to achieve a good fit between the workpiece and the packaging bag. By adjusting the air output intensity of the fan assembly through the control unit, the air guide holes can be adjusted to suit workpieces of different sizes, expanding the application range of the packaging auxiliary tooling while avoiding energy waste.

[0011] In a preferred technical solution of the present invention, the control member is connected to the diversion hole and is used to control the opening and closing of the diversion hole.

[0012] The present application provides multiple guide holes to accommodate packaging bags and workpieces of varying shapes and sizes. When blowing air onto the bag, the guide holes only need to be aligned with the edges or corners of the bag. This ensures that the bag adheres to the workpiece under the action of the blowing air for further placement. When the workpiece and bag are of different sizes, the control unit can selectively open the guide holes at the corresponding locations and close the guide holes outside the bag or at the center of the bottom of the bag. This ensures a close fit between the bag and the workpiece while also avoiding energy waste.

[0013] In a preferred technical solution of the present invention, the bottom of the packaging bag is rectangular, and the guide holes can blow air toward the bottom corners of the packaging bag.

[0014] When the bottom of the packaging bag is rectangular, its overall shape is a rectangular parallelepiped structure, and the corresponding workpiece is also a rectangular parallelepiped. When the opening of the packaging bag is placed on the upper surface of the workpiece from top to bottom, it is only necessary to blow air at the corners of the bottom of the packaging bag to ensure that the packaging bag fits the workpiece for installation. At this time, if there are a large number of guide holes, the control unit can be used to control the guide holes at the four corners of the bottom of the packaging bag to blow air. If the number of guide holes is fixed, the direction of the four guide holes can be controlled by the control unit so that they blow air towards the four corners of the bottom of the packaging bag. By blowing air at the corners of the bottom of the packaging bag, a smooth fit between the packaging bag and the workpiece can be ensured.

[0015] In a preferred technical solution of the present invention, the bottom of the packaging bag is circular, and the guide hole can blow air directly toward the bottom edge of the packaging bag.

[0016] When the bottom of the packaging bag is circular, its overall shape is a cylindrical structure, and the corresponding workpiece is also cylindrical. When the opening of the packaging bag is placed on the upper surface of the workpiece from top to bottom, it is only necessary to blow air on the edge of the bottom of the packaging bag to ensure that the packaging bag fits the workpiece. At this time, if there are a large number of guide holes, the control unit can be used to control the guide holes at the bottom edge of the packaging bag to blow air. If the number of guide holes is fixed, the direction of the four guide holes can be controlled by the control unit so that they blow air towards the bottom edge of the packaging bag. By blowing air at the bottom edge of the packaging bag, a smooth fit between the packaging bag and the workpiece can be ensured.

[0017] In a preferred technical solution of the present utility model, the diversion assembly includes a main connecting pipe, N mounting brackets, and N branch connecting pipes;

[0018] One end of the main connecting pipe is connected to the air outlet of the fan assembly, and the other end is simultaneously connected to N branch connecting pipes, the N branch connecting pipes are respectively fixed in corresponding mounting brackets, and the N branch connecting pipes are provided with guide holes facing the same direction; N is an integer greater than 1.

[0019] The present application distributes multiple guide holes in N branch connecting tubes, so that the guide holes in different branch connecting tubes can blow air to different positions on the bottom of the packaging bag. Since the bottom of the packaging bag is a flat structure, if the air is blown in the same branch connecting tube, it can only ensure that there is a downward blowing force on one line of the packaging bag, and it is impossible to achieve the fit between the packaging bag and the workpiece at all positions. The present application arranges N branch connecting tubes in parallel through the coordination of the main connecting tube and N branch connecting tubes, and the air outlet direction of the guide holes in each branch connecting tube is the same, thereby achieving blowing at all positions on the bottom of the packaging bag. At the same time, a mounting bracket is used as a fixing bracket for the branch connecting tubes to facilitate the fixation of the branch connecting tubes.

[0020] In a preferred technical solution of the present invention, the mounting bracket is fixed above the transmission line, the transmission line is used to transmit the workpiece, and the transmission direction of the workpiece is from the packaging tooling to the packaging auxiliary tooling, and N mounting brackets are arranged in parallel along the transmission direction of the workpiece.

[0021] After the packaging bag is put on the upper surface of the workpiece, the workpiece can be transmitted along the transmission line from the packaging tooling to the packaging auxiliary tooling. In the transmission direction of the workpiece, N mounting brackets are sequentially arranged in the packaging auxiliary tooling, and each mounting bracket is provided with a guide hole. This can ensure that when the workpiece and the packaging bag pass through each mounting bracket, the guide holes can blow air to the bottom of the packaging bag. After multiple blowing, the smooth fit between the packaging bag and the workpiece is ensured.

[0022] In a better technical solution of the present invention, the mounting bracket is a U-shaped structure, and the mounting bracket includes vertical rods arranged opposite to each other and horizontal rods located between the vertical rods. The horizontal rods of the mounting bracket are arranged in parallel along the transmission direction of the workpiece; the vertical rods of the mounting bracket are fixed on both sides of the transmission line.

[0023] The mounting bracket, serving as the support structure for the branch connecting pipe, can be configured as a U-shaped structure when it needs to be installed on the side of a transmission line. The U-shaped structure is open in a directional manner and includes opposing vertical bars and a horizontal bar located between the vertical bars. The two vertical bars are fixed on either side of the transmission line, and the horizontal bar is used to secure the branch connecting pipe. The diversion holes in the branch connecting pipe are arranged directly in the direction of the transmission line. The U-shaped mounting bracket allows for convenient fixing of the diversion holes.

[0024] The second purpose of this application is to provide a packaging device, including the packaging auxiliary tooling as described above.

[0025] In a preferred technical solution of the present invention, it further includes a transmission line, a packaging tool and a packaging position, and the packaging tool, the packaging auxiliary tool and the packaging position are sequentially arranged on the side of the transmission line.

[0026] By setting a packaging auxiliary tooling between the packaging tooling and the packaging position, the packaging tooling is used to put the packaging bag on the outside of the workpiece. The packaging auxiliary tooling uses the blowing effect of the guide hole to make the packaging bag on the outside of the workpiece smoothly fit on the outside of the workpiece, and the packaging position then seals the packaging bag; this application uses the packaging auxiliary position to ensure the fit between the packaging bag and the workpiece, thereby improving the sealing and aesthetics of the workpiece packaging.

[0027] The beneficial effects of the utility model are:

[0028] The present invention provides a packaging auxiliary tooling device disposed at the discharge port of the packaging tooling device, the packaging tooling device being used to place a packaging bag on the outside of a workpiece; that is, the packaging tooling device in this application is used to place a packaging bag on the outside of the workpiece, and the packaging auxiliary tooling device functions to smoothly adhere the packaging bag on the outside of the workpiece to the outside of the workpiece through the blowing effect of the guide holes, thereby improving the fit between the packaging bag and the workpiece. Specifically, the packaging auxiliary tooling device includes a fan assembly and a guide assembly, the guide assembly including M guide holes, each of the M guide holes being connected to the air outlet of the fan assembly; and the M guide holes are capable of blowing air toward the packaging bag on the outside of the workpiece. When the packaging bag is placed on the outside of the workpiece, the packaging bag cannot fit on the outside of the workpiece due to the small gravity of the packaging bag or the size difference between the packaging bag and the workpiece. The present application blows air to the packaging bag through the guide hole, and the blowing direction is the same as the direction of the packaging bag. Through the action of the airflow, it can ensure that the packaging bag is completely fitted with the workpiece, improve the sealing and aesthetics of the workpiece packaging, avoid manual position adjustment during the packaging process, and improve the level of packaging automation.

[0029] The present application also provides a packaging device, including the packaging auxiliary tooling as described above, by arranging the packaging auxiliary tooling between the packaging tooling and the packaging position, the packaging tooling is used to put the packaging bag on the outside of the workpiece, and the packaging auxiliary tooling uses the blowing effect of the guide hole to make the packaging bag on the outside of the workpiece smoothly fit on the outside of the workpiece, and the packaging position then seals the packaging bag; the present application ensures the fit between the packaging bag and the workpiece with the help of the packaging auxiliary position, thereby improving the sealing and aesthetics of the workpiece packaging.

[0040] Example 1

[0041] like Figure 1-Figure 5 As shown, a packaging auxiliary tool is provided at the discharge port of the packaging tool, and the packaging tool is used to put the packaging bag on the outside of the workpiece;

[0042] The packaging auxiliary tooling includes a fan assembly 10 and a guide assembly, the guide assembly includes M guide holes 11, and the M guide holes 11 are all connected to the air outlet of the fan assembly 10; and the M guide holes 11 can blow air toward the packaging bag outside the workpiece; M is an integer greater than 1.

[0043] In this application, the packaging tooling is used to put the packaging bag on the outside of the workpiece. The function of the packaging auxiliary tooling is to make the packaging bag on the outside of the workpiece fit smoothly to the outside of the workpiece through the blowing effect of the guide hole 11, thereby improving the fit between the packaging bag and the workpiece.

[0044] When the packaging bag is placed on the outside of the workpiece, the packaging bag cannot fit on the outside of the workpiece due to the small gravity of the packaging bag or the size difference between the packaging bag and the workpiece. The present application blows air to the packaging bag through the guide hole 11, and the blowing direction is the same as the direction of the packaging bag. Through the action of the airflow, it can ensure that the packaging bag is completely fitted with the workpiece, improve the sealing and aesthetics of the workpiece packaging, avoid manual position adjustment during the packaging process, and improve the level of packaging automation.

[0045] In the present application, the direction of the guide hole 11 is the same as the direction of the packaging bag. For example, the opening of the packaging bag is mounted on the outside of the workpiece from the top to the bottom of the workpiece. During the process of the packaging tool mounting the packaging bag, the opening of the packaging bag is mounted in the middle or below the middle of the workpiece. At this time, due to the difference between the size of the packaging bag and the workpiece, the size of the packaging bag is usually larger than the outer size of the workpiece. As a result, the packaging bag and the workpiece cannot be completely fitted together. In the present application, the guide holes 11 blow air toward the bottom of the packaging bag, and since there are multiple guide holes 11, the multiple guide holes 11 not only make the bottom of the packaging bag fit on the upper surface of the workpiece, but also the guide holes 11 facing the bottom edge of the packaging bag can blow air to the bottom edge of the packaging bag, so that the packaging bag is completely fitted on the surface of the workpiece, thereby achieving sealed and fitted packaging of the workpiece.

[0046] In the present application, there are multiple guide holes 11. In actual operation, some of the guide holes 11 can be opened for blowing air, and other guide holes 11 can be closed according to the size of the workpiece and the packaging bag.

[0047] In the present application, the angle of the guide hole 11 can be set to be adjustable. When the size of the workpiece and the packaging bag changes, it is only necessary to adjust the air outlet angle of the guide hole 11 to adapt to packaging bags and workpieces of different sizes.

[0048] Example 2

[0049] like Figure 1-Figure 5 As shown, a packaging auxiliary tool is provided at the discharge port of the packaging tool, and the packaging tool is used to put the packaging bag on the outside of the workpiece;

[0050] The packaging auxiliary tooling includes a fan assembly 10 and a guide assembly, the guide assembly includes M guide holes 11, and the M guide holes 11 are all connected to the air outlet of the fan assembly 10; and the M guide holes 11 can blow air toward the packaging bag outside the workpiece; M is an integer greater than 1.

[0051] In this application, the packaging tooling is used to put the packaging bag on the outside of the workpiece. The function of the packaging auxiliary tooling is to make the packaging bag on the outside of the workpiece fit smoothly to the outside of the workpiece through the blowing effect of the guide hole 11, thereby improving the fit between the packaging bag and the workpiece.

[0052] Furthermore, the packaging auxiliary tooling of the present application also includes a control component 15, which is electrically connected to the fan assembly 10 and is used to control the air output intensity of the fan assembly 10. In the present application, the fan assembly can specifically be a blowing device such as a blower, and the control component can be, for example, a control component for controlling the blowing intensity of the blower. For ease of presentation, the present application can integrate the fan control component and the air guide hole control component into the same chip to form a unified control component.

[0053] The air output intensity can be determined based on the size of the packaging bag and the workpiece. If both the packaging bag and the workpiece are large, such as an air conditioner housing, the larger the size of the workpiece, the larger the corresponding packaging bag. In this case, the air output intensity needs to be increased to ensure a good fit between the workpiece and the packaging bag. For example, when the workpiece is a smaller component, a lower air output intensity is required to achieve a good fit between the workpiece and the packaging bag. By adjusting the air output intensity of the fan assembly 10 through the control unit 15, it is possible to ensure that the guide hole 11 is adapted to workpieces of different sizes, thereby expanding the scope of application of the packaging auxiliary tooling and avoiding energy waste.

[0054] Furthermore, the control member 15 is connected to the diversion hole 11 and is used to control the opening and closing of the diversion hole 11 .

[0055] In this application, there are multiple guide holes 11. The reason for providing multiple guide holes 11 is to accommodate packaging bags and workpieces of different shapes and sizes. When blowing air into the packaging bag, it is sufficient to only align the guide holes 11 with the edges or corners of the packaging bag. This ensures that the packaging bag adheres to the workpiece under the action of the blowing air for further placement. When the workpiece and packaging bag are of different sizes, the control unit 15 can be used to selectively open the guide holes 11 at the corresponding positions and close the guide holes 11 outside the packaging bag or at the center of the bottom of the packaging bag. This ensures that the packaging bag and the workpiece adhere to each other while also avoiding energy waste.

[0056] As a specific embodiment, when the bottom of the packaging bag is rectangular, the guide holes 11 can blow air toward the bottom corners of the packaging bag.

[0057] When the bottom of the packaging bag is rectangular, its overall shape is a rectangular parallelepiped structure, and the corresponding workpiece is also a rectangular parallelepiped. When the opening of the packaging bag is placed on the upper surface of the workpiece from top to bottom, it is only necessary to blow air at the corner positions of the bottom of the packaging bag to ensure that the packaging bag fits the workpiece for installation. At this time, if there are a large number of guide holes 11, the control part 15 can be used to control the guide holes 11 at the four corner positions of the bottom of the packaging bag to blow air. If the number of guide holes 11 is fixed, the direction of the four guide holes 11 can be controlled by the control part 15 so that they blow air towards the four corner positions of the bottom of the packaging bag. By blowing air at the corner positions of the bottom of the packaging bag, a smooth fit between the packaging bag and the workpiece can be ensured.

[0058] As another specific embodiment, when the bottom of the packaging bag is circular, the guide holes 11 can blow air directly toward the bottom edge of the packaging bag.

[0059] When the bottom of the packaging bag is circular, its overall shape is a cylindrical structure, and the corresponding workpiece is also cylindrical. When the opening of the packaging bag is placed on the upper surface of the workpiece from top to bottom, it is only necessary to blow air on the edge of the bottom of the packaging bag to ensure that the packaging bag fits the workpiece for installation. At this time, if there are a large number of guide holes 11, the control part 15 can be used to control the guide holes 11 at the bottom edge of the packaging bag to blow air. If the number of guide holes 11 is fixed, the direction of the four guide holes 11 can be controlled by the control part 15 so that they blow air towards the bottom edge of the packaging bag. By blowing air at the bottom edge of the packaging bag, a smooth fit between the packaging bag and the workpiece can be ensured.

[0060] Furthermore, the guide assembly includes a main connecting pipe 13, N mounting brackets, and N branch connecting pipes 14, and the N mounting brackets are arranged in parallel along the transmission direction of the workpiece; one end of the main connecting pipe 13 is connected to the air outlet of the fan assembly, and the other end is simultaneously connected to N branch connecting pipes 14, and the N branch connecting pipes 14 are respectively fixed in the corresponding mounting brackets, and the N branch connecting pipes 14 are provided with guide holes 11 facing the same direction; N is an integer greater than 1.

[0061] The present application distributes multiple guide holes 11 in N branch connecting tubes 14, so that the guide holes 11 in different branch connecting tubes 14 can blow air to different positions on the bottom of the packaging bag. Since the bottom of the packaging bag is a flat structure, if blowing is performed in the same branch connecting tube 14, it can only ensure that there is a downward blowing force on one line of the packaging bag, and it is impossible to achieve the fit between the packaging bag and the workpiece at all positions. The present application arranges N branch connecting tubes 14 in parallel through the coordination of the main connecting tube 13 and N branch connecting tubes 14, and the air outlet direction of the guide holes 11 in each branch connecting tube 14 is the same, thereby achieving blowing at all positions on the bottom of the packaging bag. At the same time, a mounting bracket is used as a fixing bracket for the branch connecting tube 14 to facilitate the fixation of the branch connecting tube 14.

[0062] Furthermore, the mounting bracket is fixed above the transmission line 16, which is used to transmit the workpiece, and the transmission direction of the workpiece is from the packaging tooling to the packaging auxiliary tooling, and N mounting brackets are arranged in parallel along the transmission direction of the workpiece.

[0063] After the packaging bag is put on the upper surface of the workpiece, the workpiece can be transmitted along the transmission line 16 from the packaging tooling to the packaging auxiliary tooling. In the transmission direction of the workpiece, N mounting brackets are sequentially arranged in the packaging auxiliary tooling, and each mounting bracket is provided with a guide hole 11. This ensures that when the workpiece and the packaging bag pass through each mounting bracket, the guide hole 11 can blow air to the bottom of the packaging bag. After multiple blowings, a smooth fit between the packaging bag and the workpiece is ensured.

[0064] As a specific embodiment, the mounting bracket described in this application is a U-shaped structure, and the mounting bracket includes relatively arranged vertical rods 122 and horizontal rods 121 located between the vertical rods 122. The horizontal rods 121 of the mounting bracket are arranged in parallel along the transmission direction of the workpiece; the vertical rods 122 of the mounting bracket are fixed on both sides of the transmission line 16.

[0065] The mounting bracket serves as a support structure for the branch connecting pipe 14. When it needs to be installed on the side of the transmission line 16, the mounting bracket can be set as a U-shaped structure. The U-shaped structure opens in the direction of the U-shaped structure, that is, it includes vertical rods 122 arranged opposite to each other and a horizontal rod 121 located between the vertical rods 122. The two vertical rods 122 are fixed on both sides of the transmission line 16. The horizontal rod 121 is used to fix the branch connecting pipe 14, and the guide hole 11 in the branch connecting pipe 14 is arranged in the direction of the transmission line 16. The U-shaped mounting bracket can achieve convenient fixing of the guide hole 11.

[0066] Example 3

[0067] like Figure 1-Figure 2As shown, a packaging auxiliary tool is provided at the discharge port of the packaging tool, and the packaging tool is used to put the packaging bag on the outside of the workpiece;

[0068] The auxiliary packaging tooling includes a fan assembly 10 and a diverter assembly. The diverter assembly includes two diverter holes 11, both of which are connected to the air outlet of the fan assembly 10. These diverter holes 11 are capable of blowing air toward the packaging bag outside the workpiece. Furthermore, the diverter holes 11 are positioned above a conveyor line 16, which is used to transport workpieces from the packaging tooling to the auxiliary packaging tooling.

[0069] In this embodiment, the packaging auxiliary tooling further includes a control component 15 , which is electrically connected to the fan assembly 10 and the two guide holes 11 , and is used to control the air output intensity of the fan assembly 10 and the direction of the guide holes 11 .

[0070] Specifically, the air guide holes 11 can be disposed within the rotating shaft or fixedly connected to the rotating shaft. When the control member 15 tilts and rotates the rotating shaft, the orientation of the corresponding air guide holes 11 changes. When the workpiece is large, the control member 15 controls the air outlet directions of the two air guide holes 11 to rotate away from each other to accommodate larger workpieces. When the workpiece is small, the control member 15 controls the air outlet directions of the two air guide holes 11 to rotate toward each other to accommodate smaller workpieces.

[0071] In this application, the packaging tooling is used to put the packaging bag on the outside of the workpiece. The function of the packaging auxiliary tooling is to make the packaging bag on the outside of the workpiece fit smoothly to the outside of the workpiece through the blowing effect of the guide hole 11, thereby improving the fit between the packaging bag and the workpiece.

[0072] Specifically, in this embodiment, the bottom of the packaging bag is rectangular, and the entire packaging bag is a cuboid, and the workpiece is also a corresponding cuboid. When the packaging tool is in the packaging position, the opening of the packaging bag is placed from top to bottom on the upper surface of the workpiece. At this time, the opening of the packaging bag does not completely reach the lower surface of the workpiece and may fall to the middle of the workpiece. There is a gap between the packaging bag and the workpiece, and it does not fit completely.

[0073] Based on the size of the workpiece, the control unit 15 adjusts the airflow intensity of the air outlet module and adjusts the orientation of the two air guide holes 11 so that the two air guide holes 11 blow air directly toward the width edges of the workpiece. In other words, when the workpiece is transported along the conveyor line 16, the airflow direction of the two air guide holes 11 is directly toward both sides of the workpiece in the width direction, where the width direction refers to the direction perpendicular to the conveyor line 16. In this way, when the workpiece passes under the air guide holes 11, the two air guide holes 11 are fixed in position and blow air sequentially toward both sides of the workpiece in the width direction, ensuring a smooth fit between the packaging bag and the workpiece.

[0074] The present application blows air to the packaging bag through the guide hole 11, and the blowing direction is the same as the direction of the packaging bag. Through the action of the airflow, it can ensure that the packaging bag and the workpiece are completely fitted, thereby improving the sealing and aesthetics of the workpiece packaging, avoiding manual position adjustment during the packaging process, and improving the level of packaging automation.

[0075] Example 4

[0076] like Figure 3-Figure 5 As shown, the present embodiment provides a packaging auxiliary tool, which is arranged at the discharge port of the packaging tool, and the packaging tool is used to put the packaging bag on the outside of the workpiece;

[0077] The packaging auxiliary tooling includes a fan assembly 10 and a guide assembly, the guide assembly includes M guide holes 11, and the M guide holes 11 are all connected to the air outlet of the fan assembly 10; and the M guide holes 11 can blow air toward the packaging bag outside the workpiece; M is an integer greater than 1.

[0078] In this embodiment, the packaging auxiliary tooling further includes a control component 15 , which is electrically connected to the fan assembly 10 and the two guide holes 11 , and is used to control the air output intensity of the fan assembly 10 and to control the opening and closing of the guide holes 11 .

[0079] Specifically, when blowing air onto the bag, it is sufficient to align the guide holes 11 with the edges or corners of the bag. This ensures that the bag adheres to the workpiece under the action of the blowing air for further placement. If the workpiece and bag are of different sizes, the control unit 15 can selectively open the guide holes 11 at the corresponding locations and close the guide holes 11 outside the bag or at the center of the bottom of the bag. This ensures a close fit between the bag and the workpiece while also avoiding energy waste.

[0080] In this embodiment, the flow guide assembly includes a main connecting pipe 13, two mounting brackets, and two branch connecting pipes 14. The two mounting brackets are arranged side by side along the transmission direction of the workpiece; one end of the main connecting pipe 13 is connected to the air outlet of the fan assembly, and the other end is simultaneously connected to the two branch connecting pipes 14. The two branch connecting pipes 14 are respectively fixed in the corresponding mounting brackets. The two branch connecting pipes 14 are provided with X flow guide holes 11 facing the same direction, and X=M / 2.

[0081] The mounting brackets are fixed above a transmission line 16, which is used to transport workpieces from a packaging tool to an auxiliary packaging tool. N mounting brackets are arranged in parallel along the workpiece transport direction. The mounting brackets have a U-shaped structure and include opposing vertical rods 122 and a horizontal rod 121 positioned between the vertical rods 122. The horizontal rods 121 of the mounting brackets are arranged in parallel along the workpiece transport direction. The vertical rods 122 of the mounting brackets are fixed to both sides of the transmission line 16.

[0082] In this application, the packaging tooling is used to put the packaging bag on the outside of the workpiece. The function of the packaging auxiliary tooling is to make the packaging bag on the outside of the workpiece fit smoothly to the outside of the workpiece through the blowing effect of the guide hole 11, thereby improving the fit between the packaging bag and the workpiece.

[0083] Specifically, in this embodiment, the bottom of the packaging bag is rectangular, and the entire packaging bag is a cuboid, and the workpiece is also a corresponding cuboid. When the packaging tool is in the packaging position, the opening of the packaging bag is placed from top to bottom on the upper surface of the workpiece. At this time, the opening of the packaging bag does not completely reach the lower surface of the workpiece and may fall to the middle of the workpiece. There is a gap between the packaging bag and the workpiece, and it does not fit completely.

[0084] According to the size of the workpiece, the control part 15 adjusts the air outlet intensity of the air outlet module, and adjusts two of the guide holes 11 in each branch connecting pipe 14 to be open, and the remaining X-2 guide holes 11 are closed. It should be noted that the two open guide holes 11 are blowing air directly towards the transmission line 16, and the distance between the two guide holes 11 is equal to the size of the workpiece in the width direction. The width direction here refers to the transmission direction perpendicular to the transmission line 16. In this way, when the workpiece passes under the guide hole 11, the position of the two guide holes 11 is fixed, and air is blown on both sides of the workpiece in the width direction in turn to ensure that the packaging bag and the workpiece fit smoothly.

[0085] At the same time, the number of mounting brackets, that is, the connecting pipes 14, in this application is two, and each mounting bracket is provided with a guide hole 11. This ensures that when the workpiece and the packaging bag pass through each mounting bracket, the guide hole 11 can blow air to the bottom of the packaging bag. After multiple blowing, the smooth fit between the packaging bag and the workpiece is ensured.

[0086] The present application blows air to the packaging bag through the guide hole 11, and the blowing direction is the same as the direction of the packaging bag. Through the action of the airflow, it can ensure that the packaging bag and the workpiece are completely fitted, thereby improving the sealing and aesthetics of the workpiece packaging, avoiding manual position adjustment during the packaging process, and improving the level of packaging automation.

[0087] Example 5

[0088] like Figure 1-Figure 5As shown, this embodiment provides a packaging device comprising a transmission line 16, a packaging tool, an auxiliary packaging tool, and a packaging station. The packaging tool, the auxiliary packaging tool, and the packaging station are sequentially arranged on the sides of the transmission line 16. The structure of the auxiliary packaging tool is as described in Examples 1 to 4 and will not be described in detail here.

[0089] In this application, the packaging tooling is used to place the packaging bag on the outside of the workpiece. The function of the packaging auxiliary tooling is to make the packaging bag on the outside of the workpiece smoothly adhere to the outside of the workpiece through the blowing effect of the guide hole 11, thereby improving the fit between the packaging bag and the workpiece. The packaging position is used to seal the opening of the packaging bag to achieve the packaging of the workpiece.

[0090] When the packaging tool is in position, the opening of the packaging bag is placed on the upper surface of the workpiece from top to bottom. At this time, the opening of the packaging bag does not completely reach the lower surface of the workpiece and may fall to the middle position of the workpiece. There is also a gap between the packaging bag and the workpiece, and they cannot fit completely.

[0091] After the workpiece comes out of the packaging tooling, it moves to the packaging auxiliary tooling along the transmission line 16. The packaging auxiliary tooling uses the blowing effect of the guide hole 11 to make the packaging bag on the outside of the workpiece fit smoothly to the outside of the workpiece, and the packaging position then seals the packaging bag; this application uses the packaging auxiliary station to ensure the fit between the packaging bag and the workpiece, thereby improving the sealing and aesthetics of the workpiece packaging.

[0092] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures. In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0093] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0094] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
