Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a bagging conveying and compression mechanism and a pillow packaging line. Background Technology

[0002] Home textiles are essential items in people's lives, and pillows are indispensable in every household's bedding. Common types of pillows include: buckwheat pillows, kapok pillows, synthetic fiber pillows, latex pillows, and down pillows.

[0003] For fluffy pillow fillings such as kapok pillows, synthetic fiber pillows, and down pillows, pre-compression is required during packaging, followed by bagging and sealing. During sealing, the air inside the bag must be expelled. Currently, the cutting, bagging, and compression sealing processes for pillow packaging are all completed along the same conveyor line. However, after the cutting process, the opening of the bag faces the side of the conveyor line. This facilitates the subsequent transport of pillows from the side of the conveyor line into the bag, and also ensures that the opening of the bag is on the side of the conveyor line for heat sealing during compression. Finally, the conveyor line transports the bag to the rolling and pressing mechanism for rolling and bagging.

[0004] However, when rolling and pressing packaging bags, the bags need to be conveyed to the rolling and pressing mechanism parallel to their length. Since the seal of the packaging bag output from the conveyor line faces the side of the conveyor line, meaning the length of the packaging bag is perpendicular to the conveying direction, the packaging bag cannot directly enter the rolling and pressing mechanism after leaving the conveyor line. The angle of the packaging bag needs to be manually adjusted before it can be put into the rolling and pressing mechanism at the correct angle, which is quite troublesome. Utility Model Content

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0042] Please see Figure 1 One embodiment of this utility model provides a bagging, conveying, and compressing mechanism, comprising:

[0043] Packaging bag conveying assembly 10;

[0044] Cutting and sealing assembly 20 for cutting to form a packaging bag;

[0045] A bagging assembly 30 for opening the opening of a packaging bag;

[0046] Compression sealing assembly 40 for compressing packaging bags and sealing the opening of the packaging bags;

[0047] Angle adjustment component 50 for rotating the packaging bag by a preset angle;

[0048] The cutting and sealing assembly 20, the bagging assembly 30, and the compression sealing assembly 40 are arranged sequentially along the conveying direction of the packaging bag conveying assembly 10, and the cutting and sealing assembly 20 and the bagging assembly 30 are located on opposite sides of the packaging bag conveying assembly 10. The angle adjustment assembly 50 is set at the conveying end of the packaging bag conveying assembly 10.

[0049] It should be noted that the conveying end of the packaging bag conveying assembly 10 refers to the end where the packaging bag is detached from the packaging bag conveying assembly 10 under its conveying.

[0050] The cutting and sealing assembly 20 conveys the cut packaging bag to the packaging bag conveying assembly 10, which then conveys the packaging bag to the bagging assembly 30. The bagging assembly 30 opens the opening of the packaging bag, and the pillow is placed inside. Next, the packaging bag conveying assembly 10 conveys the packaging bag containing the pillow to the compression sealing assembly 40. The compression sealing assembly 40 compresses the packaging bag, causing the gas inside to escape and compressing the pillow. The compression sealing assembly 40 then seals the opening of the packaging bag, preventing gas from entering the packaging bag and achieving compressed packaging of the pillow, reducing its volume. At this point, the sealed position of the packaging bag faces the side of the packaging bag conveying assembly 10. Subsequently, the packaging bag conveying assembly 10 conveys the compressed and sealed packaging bag to the angle adjustment assembly 50, which rotates the packaging bag to a preset angle so that the packaging bag meets the requirements of the next process. For example, in this embodiment, the preset angle is 90°. The angle adjustment component 50 rotates the packaging bag by 90° so that the sealing position of the packaging bag is in front of or behind the packaging bag in the conveying direction of the packaging bag conveying component 10.

[0051] Please see Figure 2 and Figure 3 The specific structure of the angle adjustment component 50 can be selected according to actual needs. For example, the angle adjustment component 50 includes two sets of rotary drive rollers, each set of rotary drive rollers includes multiple rotary drive rollers, the two sets of rotary drive rollers are arranged side by side, and the two sets of rotary drive rollers can rotate in opposite directions. After the packaging bag reaches the two sets of rotary drive rollers, the rotation of the two sets of rotary drive rollers can drive the packaging bag to rotate. Alternatively, the angle adjustment component 50 includes a gripper module, which grips the packaging bag, and then the gripper module drives the packaging bag to rotate at a preset angle before putting the packaging bag down. In some optional embodiments, the angle adjustment component 50 includes a rotary support base 51 and a rotary drive module 52. The rotary support base 51 is set at the conveying end of the packaging bag conveying component 10, and the rotary drive module 52 is driven to connect with the rotary support base 51. The packaging bag conveying component 10 conveys the packaging bag to the rotary support base 51, and then the rotary drive module 52 drives the rotary support base 51 to rotate, thereby driving the packaging bag to rotate at a preset angle.

[0052] In some optional embodiments, the angle adjustment assembly 50 further includes a lifting drive module 53, a mounting bracket 54, and a plurality of auxiliary support rollers 55. The plurality of auxiliary support rollers 55 are arranged sequentially on the mounting bracket 54 along the conveying direction of the packaging bag conveying assembly 10, and the auxiliary support rollers 55 are rotatably mounted on the mounting bracket 54. A rotating support seat 51 is disposed between at least two auxiliary support rollers 55. The lifting drive module 53 is drivenly connected to the rotating support seat 51 and is able to drive the rotating support seat 51 to rise to a position higher than the auxiliary support rollers 55. The rotating support base 51 first descends to a height no higher than the auxiliary support roller 55. The packaging bag conveying assembly 10 then conveys the packaging bag onto the auxiliary support roller 55. The packaging bag can be supported by the auxiliary support roller 55 or by both the auxiliary support roller 55 and the rotating support base 51. Subsequently, the lifting drive module 53 drives the rotating support base 51 to rise, so that the packaging bag is supported only by the rotating support base 51. Then, the rotating drive module 52 drives the rotating support base 51 to rotate by a preset angle so that the packaging bag rotates to a suitable angle. Next, the lifting drive module 53 drives the rotating support base 51 to descend to a height no higher than the auxiliary support roller 55, so that the packaging bag can be supported by the auxiliary support roller 55 or by both the auxiliary support roller 55 and the rotating support base 51. Then, the packaging bag can be conveyed to the next process. During the movement of the packaging bag, there is rolling friction between the auxiliary support roller 55 and the packaging bag. The rotation of the auxiliary support roller 55 helps to smoothly guide the movement of the packaging bag.

[0053] The specific structure of the rotating support 51 can be selected according to actual needs. For example, in some optional embodiments, the multiple auxiliary support rollers 55 are divided into two groups, each group including multiple auxiliary support rollers 55. The multiple auxiliary support rollers 55 in the same group are arranged sequentially along the conveying direction of the packaging bag conveying assembly 10, and the two groups of auxiliary support rollers 55 are arranged side by side. The rotating support 51 includes a first rotating support member 511 and a second rotating support member 512. The first rotating support member 511 and the second rotating support member 512 are connected to each other. The rotating support 51 can be positioned relative to the auxiliary support rollers 55 at the first... With a first angle and a second angle, when the rotary support base 51 is at the first angle, the first rotary support member 511 can extend between the two sets of auxiliary support rollers 55, and the second rotary support member 512 can extend between two adjacent auxiliary support rollers 55 in the same set of auxiliary support rollers 55, thereby facilitating the concealment of the rotary support base 51. When the rotary support base 51 is at the second angle, the second rotary support member 512 can extend between the two sets of auxiliary support rollers 55, and the first rotary support member 511 can extend between two adjacent auxiliary support rollers 55 in the same set of auxiliary support rollers 55, thereby facilitating the concealment of the rotary support base 51. In this embodiment, the first angle can be 0° and 180°, and the second angle can be 90° and 270°.

[0054] In some optional embodiments, the rotating support 51 is provided with a plurality of first vacuum adsorption holes 513. The first vacuum adsorption holes 513 are connected to the negative pressure generating device. The first vacuum adsorption holes 513 can adsorb the packaging bag onto the rotating support 51, thereby preventing the packaging bag from slipping between the packaging bag and the rotating support 51 when the rotating support 51 rotates, which would prevent the packaging bag from rotating to the predetermined angle correctly.

[0055] The specific structure of the lifting drive module 53 can be selected according to actual needs. For example, the lifting drive module 53 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module. The specific structure of the rotary drive module 52 can be selected according to actual needs. For example, the rotary drive module 52 can use a rotary drive motor.

[0056] In this embodiment, the lifting drive module 53 may use multiple cylinders, which are connected to the transfer bracket. The rotation drive module 52 is installed on the transfer bracket, and the output shaft of the rotation drive module 52 is driven to the rotation support 51. The lifting drive module 53 drives the rotation drive module 52 and the rotation support 51 to rise and fall by driving the transfer bracket to rise and fall.

[0057] Please see Figure 4 and Figure 5 In some optional embodiments, the cutting and sealing assembly 20 includes a first sealing module 21, a cutting module 22, and a feeding module 23. The first sealing module 21 and the cutting module 22 are disposed on one side of the packaging bag conveying assembly 10 and arranged sequentially in the direction close to the packaging bag conveying assembly 10. The feeding module 23 is disposed on one side of the cutting module 22. The feeding module 23 conveys the tubular bag to the packaging bag conveying assembly 10. The tubular bag conveyed by the feeding module 23 passes through the cutting module 22 and the first sealing module 21. After the length of the bag reaches the packaging bag conveying assembly 10 via the cutting module 22 reaches the appropriate length, the first sealing module 21 seals one end of the tubular bag, forming a welding mark. The cutting module 22 cuts the tubular bag to form a packaging bag of the appropriate length. The welding mark is equivalent to sealing one end of the packaging bag, while the other end of the packaging bag is not sealed and faces the bagging assembly 30. This allows the packaging bag conveying assembly 10 to perform the bagging operation immediately after conveying the packaging bag to the bagging assembly 30, without having to adjust the angle of the packaging bag.

[0058] The feeding module 23 typically employs a winding module, which includes at least a winding roller on which the tubular bag is wound up. The winding roller can be connected to a motor to achieve active feeding. It should be noted that the packaging bag is cut from the tubular bag. Cutting the packaging bag from the tubular bag without sealing it will result in a packaging bag with openings at both ends. Therefore, one end of the packaging bag is sealed first, while the other end remains unsealed, forming an opening. This allows the pillow to be inserted through the opening of the packaging bag, which is then sealed again.

[0059] The first sealing module 21 can weld the upper and lower film of the tubular bag together, creating a weld line on the tubular bag. The cutting module 22 then cuts the tubular bag, and the cut portion becomes the packaging bag. In this embodiment, the first sealing module 21 includes a first sealing drive module 211, a first sealing support seat 212, and a first welding seat 213. The first sealing drive module 211 drives the first welding seat 213 to move up and down on the first sealing support seat 212. The tubular bag passes between the first welding seat 213 and the first sealing support seat 212. The first welding seat 213 presses the tubular bag against the first sealing support seat 212 and then welds it. This example is not limited to this one.

[0060] The specific structure of the cutting module 22 can be selected according to actual needs. For example, the cutting module 22 includes a cutting blade 221 and a cutting drive module 222. The cutting blade 221 can be raised and lowered under the drive of the cutting drive module 222. After the cutting blade 221 descends, it cuts the tubular bag. In this embodiment, the first sealing drive module 211 is also connected to the cutting drive module 222, driving the first welding seat 213 and the cutting drive module 222 to rise and fall together. The cutting blade 221 is arranged on the side of the first welding seat 213 away from the packaging bag conveying assembly 10. To facilitate cutting, the first sealing drive module 211 is also connected to a tubular bag pressing seat 214. The tubular bag pressing seat 214, the cutting blade 221, and the first welding seat 213 are arranged in sequence in the direction close to the packaging bag conveying assembly 10. The tubular bag pressing seat 214 and the first welding seat 213 together press the tubular bag onto the first sealing support seat 212, thereby straightening the tubular bag. Then the cutting blade 221 cuts, achieving stable and accurate cutting and avoiding cutting failure. An obstacle space 215 can be provided on the first sealing support seat 212 to avoid the cutting blade 221 from passing through.

[0061] The specific structure of the first sealing drive module 211 and the cutting drive module 222 can be selected according to actual needs. For example, the first sealing drive module 211 and the cutting drive module 222 can adopt a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module or a linear motor translation drive module, etc., so as to drive the first welding seat 213 and the cutting tool 221 to rise and fall accordingly.

[0062] In some optional embodiments, the cutting and sealing assembly 20 further includes a first upper bag film adsorption module 24, a first lower bag film adsorption module 25, a first bag film lifting drive module 26, a bag lifting component 27, and a bag lifting translation drive module 28. The first lower bag film adsorption module 25 is disposed on one side of the packaging bag conveying assembly 10. The first upper bag film adsorption module 24 is vertically and vertically disposed above the first lower bag film adsorption module 25. Both the first lower bag film adsorption module 25 and the first upper bag film adsorption module 24 are provided with a plurality of second vacuum adsorption holes for connecting to a negative pressure generating device. The first bag film lifting drive module 26 is drivenly connected to the first upper bag film adsorption module 24. The bag lifting component 27 is disposed above the packaging bag conveying assembly 10. The bag lifting translation drive module 28 is drivenly connected to the bag lifting component 27. The bag lifting component 27 moves towards or away from the first sealing module 21 under the drive of the bag lifting translation drive module 28. The first lower bag film adsorption module 25 can be located on the side of the first sealing module 21 facing the packaging bag conveying assembly 10, or it can be located on the side of the first sealing module 21 away from the packaging bag conveying assembly 10. In this embodiment, the first lower bag film adsorption module 25 is located on the side of the first sealing module 21 away from the packaging bag conveying assembly 10, and the direction in which the bag lifting component 27 is moved by the bag translation driving module 28 is perpendicular to the conveying direction of the packaging bag conveying assembly 10.

[0063] After the tubular bag is conveyed to the end and reaches between the first lower bag film adsorption module 25 and the first bag film lifting drive module 26, the negative pressure generating device is activated, so that a negative pressure is formed at the second vacuum adsorption hole of the first lower bag film adsorption module 25 and adsorbs the lower bag film of the tubular bag. Meanwhile, the first upper bag film adsorption module 24 is lowered under the drive of the first bag film lifting drive module 26, so that the first upper bag film adsorption module 24 abuts against the upper bag film of the tubular bag. Then, the first bag film lifting drive module 26 drives the first upper bag film adsorption module 24 to rise, so that the upper bag film of the tubular bag is lifted, thereby initially opening the opening of the tubular bag. Then, the bag lifting component 27 is extended into the tubular bag from the opening under the drive of the bag lifting translation drive module 28 and supported by the bag lifting component 27. As the feeding module 23 conveys the tubular bag, the end of the tubular bag will move toward the packaging bag conveying assembly 10 away from the first sealing module 21. The bag lifting piece 27 also moves with the end of the tubular bag under the drive of the bag lifting translation drive module 28. When the first sealing module 21 and the cutting module 22 complete the sealing and cutting operations, the bag lifting piece 27 can detach from the tubular bag, which helps the packaging bag to be smoothly spread on the packaging bag conveying assembly 10, avoiding wrinkles in the packaging bag, or preventing the end of the channel from bending and shifting due to friction when the end of the tubular bag moves on the packaging bag conveying assembly 10, thus preventing the posture of the packaged bag formed after cutting from not meeting the requirements on the packaging bag conveying assembly 10.

[0064] The specific structure of the first bag film lifting drive module 26 and the bag translation drive module 28 can be selected according to actual needs. For example, the first bag film lifting drive module 26 and the bag translation drive module 28 can adopt a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0065] Please see Figure 6 and Figure 7The specific structure of the bagging assembly 30 can be selected according to actual needs. For example, in some optional embodiments, the bagging assembly 30 includes a second upper bag film adsorption module 31, a second lower bag film adsorption module 32, a second bag film lifting drive module 33, a first bag support component 34, a second bag support component 35, a bag support lifting drive module 36, and a bag support translation drive module 37. The second lower bag film adsorption module 32 is disposed on one side of the packaging bag conveying assembly 10, and the second upper bag film adsorption module 31 is movably disposed above the second lower bag film adsorption module 32. Both the second lower bag film adsorption module 32 and the second upper bag film adsorption module 31 are provided with a plurality of first... The three vacuum adsorption holes 311 are used to connect to the negative pressure generating device. The second bag film lifting drive module 33 is driven to connect with the second upper bag film adsorption module 31. The first bag support 34 and the second bag support 35 can be lifted and lowered on one side of the packaging bag conveying assembly 10. The second bag support 35 is located above the first bag support 34. The bag lifting drive module 36 is driven to connect with the second bag support 35. The bag translation drive module 37 is driven to connect with the first bag support 34 and the second bag support 35. The first bag support 34 and the second bag support 35 move closer to or further away from the packaging bag conveying assembly 10 under the drive of the bag translation drive module 37.

[0066] The tubular bag is cut by the cutting and sealing assembly 20 to obtain a packaging bag with one end sealed. At this time, the sealed end of the packaging bag faces the cutting and sealing assembly 20, while the unsealed end of the packaging bag faces the bag-covering assembly 30. The packaging bag conveying module conveys the packaging bag. After the unsealed end of the packaging bag reaches between the second upper bag film adsorption module 31 and the second lower bag film adsorption module 32, the conveying stops. Then, the negative pressure generating device is activated, so that a negative pressure is formed at the third vacuum adsorption hole 311 of the second lower bag film adsorption module 32 and adsorbs the lower bag film of the packaging bag. The second upper bag film adsorption module 31 is lowered under the drive of the second bag film lifting drive module 33, so that the second upper bag film adsorption module 31 abuts against the upper bag film of the packaging bag. Then, the second bag film lifting drive module 33 drives the second upper bag film adsorption module 31 to rise, so that the upper bag film of the packaging bag is lifted, thereby initially opening the bag opening.

[0067] Subsequently, the bag-supporting translation drive module 37 moves the first bag-supporting component 34 and the second bag-supporting component 35 toward the opening of the packaging bag, causing them to extend into the opening. At this point, the adsorption of the packaging bag by the second upper bag film adsorption module 31 and the second lower bag film adsorption module 32 is released, and the second upper bag film adsorption module 31 is raised to avoid the subsequent movement of the second bag-supporting component 35. Then, the bag-supporting lifting drive module 36 moves the second bag-supporting component 35... As the first support member 34 maintains the bottom of the bag opening, the second support member 35 rises and moves the top of the bag opening upward, thus opening the bag opening to a sufficient size. Then, the pillow can be stuffed into the bag through the bag opening. After the pillow is stuffed, the second support member 35 descends, and the second support member 35 and the first support member 34 exit from the bag opening. Subsequently, the bag conveying assembly 10 moves the bag containing the pillow to the compression sealing assembly 40.

[0068] The specific structure of the second bag film lifting drive module 33 and the bag supporting translation drive module 37 can be selected according to actual needs. For example, the second bag film lifting drive module 33 and the bag supporting translation drive module 37 can adopt a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0069] Please see Figure 8 In some optional embodiments, the compression sealing assembly 40 includes a pressing seat 41, a pressing drive module 42, and a second sealing module 43. The pressing seat 41 is vertically and flexibly positioned above the packaging bag conveying assembly 10. The pressing drive module 42 is drivenly connected to the pressing seat 41. The second sealing module 43 is positioned on one side of the packaging bag conveying assembly 10 and is located on the same side of the packaging bag conveying assembly 10 as the bag-covering assembly 30. The position of the second sealing module 43 corresponds to one side of the pressing seat 41, so that when the packaging bag containing the pillow moves under the pressing seat 41, the opening of the packaging bag is also positioned at the second sealing module 43. The pressing drive module 42 drives the pressing seat 41 to press down, thereby compressing the packaging bag and the pillow, thereby expelling the air inside the packaging bag and reducing the thickness of the pillow. Then, the second sealing module 43 seals the opening of the packaging bag, thereby achieving the sealing of the pillow by the packaging bag.

[0070] The second sealing module 43 can weld the upper and lower bag films of the packaging bag together, forming a weld line and sealing the bag opening. In this embodiment, the second sealing module 43 includes a second sealing drive module 431, a second sealing support base 432, and a second welding base 433. The second sealing drive module 431 drives the second welding base 433 to move up and down on the second sealing support base 432. The packaging bag is conveyed by the packaging bag conveying assembly 10 and arrives between the second welding base 433 and the second sealing support base 432. The second welding base 433 presses the packaging bag against the second sealing support base 432 and then welds it. This example is not limited to this one. In addition, the second sealing drive module 431 can be installed on one side of the pressure base 41, so that the second welding base 433, the pressure base 41, and the second welding base 433 can move up and down together under the drive of the pressure drive module 42. The structure of the second sealing module 43 can be referred to the structure of the first sealing module 21. Its principle is also known to those skilled in the art, and will not be described in detail here.

[0071] The specific structure of the pressure drive module 42 can be selected according to actual needs. For example, the pressure drive module 42 can be a lead screw drive module, a rotary motor drive module, a belt drive module, a cylinder drive module, or a linear motor drive module. In this embodiment, the pressure drive module 42 includes multiple pressure drive cylinders. The output shaft of the pressure drive cylinder is connected to the pressure seat 41, driving the pressure seat 41 to rise and fall relative to the packaging bag conveying assembly 10.

[0072] The aforementioned bagging and conveying compression mechanism can be applied to a pillow packaging line, which includes: a bagging and conveying compression mechanism as described above.

[0073] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
