Description

Technical Field

[0001] The invention relates to the technical field of fabric product packaging equipment, and in particular to an automatic clothing packaging machine and an automatic packaging method thereof. Background Art

[0002] In the prior art, automatic folding clothes devices have been able to achieve automatic folding and packaging of clothes, improving processing efficiency and reducing production costs. However, these devices still have some limitations in practical applications.

[0003] For example, in the prior art, the authorization announcement number: CN 210634873 U discloses a device for automatically packaging clothing, tearing glue and sealing bags. The device realizes the automatic folding, tearing glue and bagging of clothing through a conveying device, a clothing scraping device, a bag supporting device, a bag placing device, a bag pressing device, a glue tearing device, a bag sealing device and a control device, which can improve efficiency and reduce production costs.

[0004] However, the prior art has several limitations. Since the width of a clothing packaging bag is generally about 30 cm or even larger, when the bag opening is stretched, the middle of the wider bag opening will sag into an arc due to the effect of gravity. Therefore, the height of the bag opening needs to be stretched higher to facilitate the loading of clothing into the bag. Therefore, when the existing packaging machine stretches the bag opening, the stretching degree of the bag opening needs to be greater than the width and height of the fabric by more than 10% to facilitate the feeding of the fabric into the bag. For example, the width of the folded clothes is 30 cm and the height is 1 cm, and the packaging bag machine needs to use a packaging bag with a width of 36 cm or even larger to be used for the packaging action of this type of packaging machine. This makes the packaging bag much larger than the fabric after packaging, that is, the packaging bag is not full enough after packaging, resulting in a large space occupied by the packaging bag when the fabric is stored and transported, and the packaging is not beautiful enough. Moreover, when tearing the glue, it is necessary to clamp the glue strip and tear the glue strip vertically upward to expose the glue surface. This method of tearing the glue strip pulls the glue strip too much, which easily causes the adhesive part of the plastic bag (i.e., the glue strip) to stretch and deform. Therefore, the prior art needs to be further improved. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide an automatic clothing packaging machine that can realize automated operations such as folding, bag opening, glue tearing and bag sealing of the fabric, and can also adjust the bag opening height according to the size of the folded fabric, so that the fabric is fuller and more beautiful after packaging.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The invention discloses an automatic clothing packaging machine, comprising a folding device for folding fabrics, a bag supply device for conveying fabric plastic bags, a clothes clamping device for conveying the folded fabrics into the fabric plastic bags, a bag-stretching device for stretching the fabric plastic bags and adjusting the stretching width and height according to the size of the folded fabrics, a plastic bag glue-tearing and sealing device for tearing off the glue strips on the fabric plastic bags and sealing the fabric plastic bags, and a conveying device for conveying fabrics. The folding device folds the fabrics into blocks, and the bag supply device conveys the fabric plastic bags to the bag-stretching device. The bag-stretching device blows air into the fabric plastic bags to open the bag opening, and stretches the bag opening according to the width and height of the folded fabrics and keeps the bag opening in a tensioned state. The clothes clamping device clamps the folded fabrics and conveys them into the stretched fabric plastic bags. Then, the conveying device conveys the fabric plastic bags containing the fabrics to the plastic bag glue-tearing and sealing device. The plastic bag glue-tearing and sealing device performs translational tearing of the glue strips of the fabric plastic bags and seals the plastic bags.

[0008] An automatic packaging method of the automatic clothing packaging machine, the automatic clothing packaging machine comprises a frame, the frame has two layers, the clothing clamping device, bag supply device, bag support device and plastic bag glue tearing and sealing device of the automatic clothing packaging machine are arranged on the lower layer of the frame, and the clothing folding device of the automatic clothing packaging machine is arranged on the upper layer of the frame and is located above the clothing clamping device; the automatic packaging method comprises:

[0009] The folding device folds the fabric into blocks and places them on the clamping device, while the bag supply device delivers the plastic bags to the bag support device.

[0010] The bag-opening device blows air into the fabric plastic bag to open the bag opening, and opens the bag opening according to the width and height of the folded fabric and keeps the bag opening in a tensioned state;

[0011] The folded fabric is clamped by the clothing clamping device and sent into the opened fabric plastic bag;

[0012] The conveying device conveys the fabric plastic bag containing the fabric to the plastic bag tearing and sealing device;

[0013] The plastic bag peeling and sealing device peels the glue strip of the fabric plastic bag horizontally and seals the plastic bag, and the sealed fabric plastic bag is delivered by the conveying device.

[0014] Compared with the prior art, the automatic clothing packaging machine provided by the present invention realizes the actions of folding fabric, feeding fabric plastic bags, supporting fabric plastic bags, feeding fabric into fabric plastic bags, tearing off the glue of fabric plastic bags and sealing, and the entire process from folding clothes to sealing bags does not require manual participation, and realizes automatic operation. Moreover, when opening the bag mouth, the plastic bag supporting device also adjusts the width and height of the bag mouth of the fabric plastic bag according to the size of the fabric, and tightens the bag mouth, so as to realize the use of smaller packaging bags to package the fabric, making the packaged fabric fuller and more beautiful.

[0045] Rack 77 DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] The automatic clothing packaging machine provided by the present invention is mainly used for packaging fabrics. The fabrics include but are not limited to clothes, pants, socks, gloves, towels, bedding, etc. The packaging can automatically complete operations such as fabric folding, bag supply, bag filling and sealing, thereby achieving the purpose of automatic packaging. Moreover, the coordinated work of the bag-filling assembly, the bag width adjustment assembly and the tensioning cylinder of the bag-filling device can select the most suitable bag-filling method according to different fabric plastic bags and fabric sizes. When the fabric plastic bag is much larger than the fabric, the bag-filling assembly will open the fabric plastic bag, and the tensioning cylinder will maintain the tensioning state of the bag-filling assembly, and then feed the fabric. If the fabric plastic bag is only slightly larger than the fabric, the bag-filling assembly will first open the fabric plastic bag, and then lower the bag-filling height after a small part of the fabric is fed in. The tensioning cylinder is responsible for tensioning the bag opening to widen the bag opening, and finally feed the second half of the fabric to complete the bag-filling. Such a design makes the packaged fabric fuller and more beautiful.

[0048] See also Figure 1 , Figure 2 and Figure 3 The automatic clothing packaging machine provided by the present invention comprises a folding device 1 for folding fabrics, a bag supply device 2 for conveying a fabric plastic bag 100, a clothing clamping device 3 for conveying the folded fabric into the fabric plastic bag 100, a bag-opening device 4 for opening the fabric plastic bag 100 and adjusting the opening width and height according to the size of the folded fabric, a plastic bag glue-tearing and sealing device 5 for tearing off the glue strip on the fabric plastic bag 100 and sealing the fabric plastic bag 100, and a conveying device 6 for conveying fabrics. The folding device 1 folds the fabrics into blocks. At the same time, the bag supply device 2 conveys the fabric plastic bag 100 to the bag-stretching device 4, which blows air into the fabric plastic bag 100 to open the bag opening, and stretches the bag opening according to the width and height of the fabric plastic bag 100 and keeps the bag opening in a tensioned state, and then the clothing clamping device 3 clamps the folded fabric and feeds it into the opened fabric plastic bag 100, and then the conveying device 6 conveys the fabric plastic bag 100 containing the fabric to the plastic bag glue tearing and sealing device 5, and the plastic bag glue tearing and sealing device 5 translates the glue strip of the fabric plastic bag 100 and seals the plastic bag. The entire process from folding clothes to sealing bags does not require manual intervention and can be automated. When bagging, the width and height of the bag opening of the fabric plastic bag 100 are adjusted according to the size of the fabric, and then the bag opening is tightened to prevent the middle of the bag opening from sagging, which is convenient for loading the fabric and can reduce the requirements for the size of the packaging bag (for example, the same fabric requires a 36CM wide packaging bag using an existing packaging machine, but the present application only requires a 34CM wide packaging bag by tightening the bag opening), making the packaged fabric fuller and more beautiful. In addition, the method of first opening and then tightening is adopted, so that the plastic bag will not be damaged when the bag opening is opened.

[0049] Please also read Figure 4 , Figure 5 and Figure 6The folding device 1 comprises a left longitudinal folding assembly 11, a right longitudinal folding assembly 12, a first fold transverse folding assembly 13, a second fold transverse folding assembly 14 and a garment-dropping opening and closing assembly 15. The left longitudinal folding assembly 11 is arranged opposite to the right longitudinal folding assembly 12 and is located on both sides of the first fold transverse folding assembly 13, the second fold transverse folding assembly 14 and the garment-dropping opening and closing assembly 15, and can be relatively folded inwards to fold the fabric into a long strip. The first fold transverse folding assembly 13, the second fold transverse folding assembly 14 and the garment-dropping opening and closing assembly 15 are arranged in sequence, the first fold transverse folding assembly 13 is folded relative to the second fold transverse folding assembly 14, the second fold transverse folding assembly 14 is folded relative to the garment-dropping opening and closing assembly 15, and the fabric is folded into a square shape, and finally the folded fabric is placed in the garment-dropping opening and closing assembly 15, which is opened by the garment-dropping opening and closing assembly 15 to make the fabric fall to the clamping device 3.

[0050] The folding device 1 further includes a width adjustment component 16 for adjusting the distance between the left longitudinal folding component 11 and the right longitudinal folding component 12 to accommodate folding of fabrics of different sizes. The width adjustment component 16 can be a manual adjustment structure or an electric adjustment structure, and its structure is not limited here. Since this structure is a prior art, it will not be described here.

[0051] The left longitudinal folding assembly 11 and the right longitudinal folding assembly 12 have the same structure, and include a clothes folding motor 111, a longitudinal folding flap 112, a longitudinal folding crank 113, a longitudinal folding connecting rod 114 and a longitudinal folding hinge 115. The longitudinal folding flap 112 is connected to the width adjustment assembly 16 through the longitudinal folding hinge 115. One end of the longitudinal folding connecting rod 114 is connected to the longitudinal folding flap 112, and the other end thereof is connected to one end of the longitudinal folding crank 113. The other end of the longitudinal folding crank 113 is connected to the clothes folding motor 111. When the clothes folding motor 111 rotates forward, the longitudinal folding connecting rod 114 is raised through the longitudinal folding crank 113 to control the longitudinal folding flap 112 to fold inward, so as to achieve the clothes folding effect. When the clothes folding motor 111 rotates reversely, the longitudinal folding flap 112 is reset to prepare for the next folding.

[0052] The structures of the first fold transverse folding assembly 13 and the second fold transverse folding assembly 14 are similar to those of the left longitudinal folding assembly 11 and the right longitudinal folding assembly 12 , and are not described in detail herein.

[0053] The clothing opening and closing assembly 15 includes two clothing placing boards 151 that open and close relative to each other and an opening and closing module 152 for controlling the relative opening and closing of the two clothing placing boards 151. The opening and closing module 152 is connected to the clothing placing boards 151 to control the relative opening and closing of the clothing placing boards 151, so as to make the folded fabrics on the clothing placing boards 151 fall and be transported to the clothing clamping device 3.

[0054] The opening and closing module 152 can be driven by a motor with a synchronous belt or by a cylinder with a synchronous belt, as long as the relative opening and closing of the two clothing boards 151 can be achieved. The structure of the opening and closing module 152 is not limited here.

[0055] When folding the fabric, the fabric is laid flat on the folding device 1, and is folded relatively by the left longitudinal folding assembly 11 and the right longitudinal folding assembly 12 so that the fabric is folded into a long strip, and then folded by the first folding transverse folding assembly 13 and the second folding transverse folding assembly 14 so that the fabric is folded into a square and placed on the clothing placing board 151. Finally, the opening and closing module 152 controls the two clothing placing boards 151 to separate, so that the fabric on the clothing placing boards 151 falls and then closes, preparing for the folding and transmission of the next piece of fabric.

[0056] See also Figure 7 , Figure 8 , Fig. 9 and Fig.10 The jacket device 3 includes a jacket bottom plate 31, two jacket top plates 32 that open and close relative to the jacket bottom plate 31, a jacket lifting assembly 33 for controlling the lifting and lowering of the jacket top plates 32, and a jacket moving assembly 34 for controlling the movement of the jacket bottom plate 31 and the jacket top plates 32. The jacket bottom plate 31 is initially located at the bottom of the garment placing board 151, and is used to catch the fabric that falls from the garment placing board 151. When the fabric falls from the garment placing board 151 and is placed on the jacket bottom plate 31, the jacket lifting assembly 33 controls the jacket top plates 32 to cooperate with the jacket bottom plate 31 to clamp the fabric, and then the jacket moving assembly 34 transports the fabric to the bag holding device 4. The front end of the jacket top plate 32 is set at an angle, which plays a guiding role when bagging, and is more conducive to bagging of fabric.

[0057] The jacket moving assembly 34 includes a jacket feeding guide rail 341, a jacket bracket 342, a connecting block 343, two jacket synchronous belts 344, a jacket synchronous shaft 345 and a jacket motor 346. The jacket motor 346 is connected to the jacket synchronous shaft 345. The jacket synchronous belt 344 is arranged at both ends of the jacket synchronous shaft 345. The connecting block 343 is fixed on the jacket synchronous belt 344 and connected to the jacket bracket 342. The jacket bracket 342 is slidably arranged on the jacket feeding guide rail 341. When feeding fabric, the jacket motor 346 is started, and the jacket synchronous belt 344 is synchronously moved through the jacket synchronous shaft 345, and the connecting block 343 drives the jacket bracket 342 to move synchronously to transport fabric. With the assistance of the jacket feeding guide rail 341, the jacket bracket 342 has higher stability in movement, which is convenient for bagging fabric.

[0058] Specifically, the jacket lifting assembly 33 includes a jacket lifting cylinder 331, a jacket lifting rail 332, an opening and closing guide plate 333, a guide plate positioning cross bar 334 and a cam 335. The telescopic end of the jacket lifting cylinder 331 is connected to the jacket lifting rail 332, the guide plate positioning cross bar 334 is fixed to the top of the jacket bracket 342, the opening and closing guide plate 333 is fixed on the guide plate positioning cross bar 334, the cam 335 is arranged at the end of the jacket top plate 32, the opening and closing guide plate 333 has a vertically inclined through groove 3331 (i.e., half of a "Y" shape), and the cam 335 is located in the through groove 3331. In the initial state, the jacket lifting cylinder 331 is in an extended state (i.e., the cam 335 is located at the top of the "Y"-shaped through slot 3331), so that the fabric will not come into contact with the jacket top plate 32 when falling from the folding device 1, thereby keeping the fabric that falls onto the jacket bottom plate 31 in a folded state. The jacket lifting cylinder 331 controls the jacket lifting guide rail 332 to retract, so that the cam 335 moves downward along the through slot 3331 on the opening and closing guide plate 333, so that the two jacket top plates 32 can slowly move together and clamped to the jacket bottom plate 31.

[0059] The jacket lifting assembly 33 also includes a jacket translation guide rail 336, and the jacket translation guide rail 336 is fixed on the jacket lifting guide rail 332. The opening and closing guide plate 333 is arranged on the jacket translation guide rail 336, so that the opening and closing guide plate 333 can adjust the distance between the two as needed to adapt to fabrics of different sizes.

[0060] Please continue reading Figure 3 The bag supply device 2 is a lifting bag supply device, which transports the fabric plastic bag 100 and rises to the position where it docks with the plastic bag support device 4, and cooperates with the plastic bag support device 4 to press the mouth of the fabric plastic bag 100, and then the plastic bag support device 4 blows air into the mouth of the fabric plastic bag 100 and opens the bag mouth, creating conditions for the jacket moving component 34 to feed the fabric into the fabric plastic bag 100. In this embodiment, the folding and jacketing actions can be completed before the bag mouth is opened or when the bag mouth is opened. The entire bag supply process is automated, without manual intervention, and the efficiency is improved. Since the structure of the bag supply device 2 is a prior art, it is not a protection point of the present invention, so the specific mechanical structure and driving method are not described in detail here. In general, the lifting bag supply device 2 is one of the components in the automated packaging line. It ensures that the fabric plastic bag 100 can be accurately transported to the designated position, and works in conjunction with the plastic bag support device 4 to achieve automated bag supply and support of the fabric.

[0061] See also Fig.11 , Fig.12 , Fig.13 and Fig.14The plastic bag stretching device 4 comprises two bag stretching components 41 which are arranged opposite to each other and are used to stretch the fabric plastic bag 100 and can adjust the stretching height and width, a bag width adjusting component 42 which is used to adjust the distance between the two bag stretching components 41 according to the width of the fabric after folding, a bag blowing component 43 which is used to blow open the fabric plastic bag 100, and a tensioning cylinder 44 which is used to control the bag stretching component 41 to keep the bag opening in a tensioned state. The bag width adjusting component 42 adjusts the position of the bag stretching component 41 according to the width of the fabric after folding, and the bag blowing component 43 presses the sealing part (such as Figure 2 The dotted line framed portion) is used to blow air into the fabric plastic bag 100 to open the bag opening, the bag-holding component 41 extends into the fabric plastic bag 100 and holds the bag opening open, the bag-holding component 41 adjusts the bag-holding height according to the fabric height, and at the same time, the tensioning cylinder 44 controls the bag-holding component 41 to adjust the bag-holding width so that the bag opening remains in a tensioned state. Through the cooperation between the bag-holding component 41, the bag width adjustment component 42 and the tensioning cylinder 44, different bag-holding methods can be selected according to the size ratio of the fabric plastic bag 100 to the fabric, which is more practical.

[0062] In a first optional embodiment, the bag-stretching assembly 41 adjusts the bag-stretching height according to the fabric height, specifically including: the bag-stretching assembly 41 rotates outward and extends into the fabric plastic bag 100 to open the bag opening, and the width and height of the bag opening are respectively greater than the width and height of the fabric after folding. After the bag-stretching assembly 41 straddles the bag in place, the bag opening is tightened by the tensioning cylinder 44, so that the bag opening is tightened to avoid the concave middle of the bag opening to achieve rapid bag-stretching and bagging. Moreover, when the bag opening is tightened, the bag-stretching width can be further increased, so that a plastic bag slightly smaller than the set size can be used, thereby making the fabric fuller after packaging. Existing packaging machines and bag-packing machines need to use packaging bags with a width of 36CM or even larger. Through the first optional embodiment, a packaging bag with a width of only 34CM can be achieved by tensioning the bag opening.

[0063] In a second optional embodiment, the bag-stretching assembly 41 adjusts the bag-stretching height according to the fabric height, specifically comprising: the bag-stretching assembly 41 rotates outwardly and extends into the fabric plastic bag 100 to stretch the bag opening to a first height, and at the same time stretches the bag opening to a first width, and the first width is smaller than the width of the folded fabric, and the bag opening is stretched by the tensioning cylinder 44; at this time, although the stretched width of the bag opening is smaller than the fabric width, due to the restraint and guiding effect of the bag-stretching assemblies 41 on both sides, the front end of the fabric can still smoothly enter the fabric plastic bag 100, and when the bag-stretching assembly 41 detects that the fabric to be packaged is fed into the fabric plastic bag 100, and the preset length of the front end of the fabric to be packaged is fed into the fabric plastic bag 100, the bag-stretching assembly 41 lowers the stretched height of the bag opening to a second height, and at the same time the tensioning cylinder 44 stretches the bag opening to a second width and keeps it stretched; wherein the first height is greater than the second height, and the first width is less than the second width, so as to meet the packaging requirements of a smaller size difference between the fabric plastic bag 100 and the fabric, so as to make the fabric packaging fuller. The existing packaging machine bag packaging machine needs to use a packaging bag with a width of 36CM or even larger. The second optional embodiment can realize a packaging bag with a width of only 32CM or even 30CM by tensioning the bag opening.

[0064] Please also read Fig.15 and Fig.16 The bag support assembly 41 includes a bag opening base 411, a bag opening lower paddle 412, a bag opening upper paddle 413, an upper paddle lifting motor 414, a swing lower support 415, a swing upper support 416 and a bag opening cylinder 417. The bag opening cylinder 417 is fixed on the bag opening base 411, the swing lower support 415 is connected to the movable end of the bag opening cylinder 417, the bag opening lower paddle 412 is fixedly connected to the swing lower support 415, and the upper paddle lifting motor 414 is fixedly connected to the lower support 415. Fixed on the bag opening base 411, the swing upper support 416 is hinged with the screw nut of the upper paddle lifting motor 414, and the hinge axis is coaxial with the axis of the swing lower support 415, the bag opening upper paddle 413 is fixedly connected to the swing upper support 416, and the swing upper support 416 is liftably connected to the guide member 419 on the swing lower support 415, and the guide member 419 plays a role in assisting the upper paddle lifting motor 414 to control the lifting of the swing upper support 416.

[0065] The expansion and contraction of the bag opening cylinder 417 drives the swing lower support 415 to rotate, so that the bag opening lower paddle 412 arranged on the swing lower support 415 rotates synchronously. Since the swing upper support 416 is hinged with the screw nut of the upper paddle lifting motor 414, and the hinge axis is coaxial with the axis of the swing lower support 415, the bag opening upper paddle 413 and the bag opening lower paddle 412 rotate synchronously, and the upper paddle lifting motor 414 can also control the lifting and lowering of the swing upper support 416 to control the height of the bag opening upper paddle 413, and then control the bag support height, so as to be suitable for different fabric packaging. Specifically, the bag opening lower paddle 412 has a guide portion 4121 that facilitates the feeding of the fabric to be packaged, so that the fabric to be packaged can be more smoothly fed into the fabric plastic bag 100.

[0066] In this embodiment, the lower pocket opening paddle 412 is L-shaped, that is, the lower pocket opening paddle 412 includes a transverse piece (not numbered in the figure) and a vertical piece (not numbered in the figure) arranged on the transverse piece, and the guide portion 4121 is arranged on the lower pocket opening paddle 412 (such as on the transverse piece) and is arranged at an obtuse angle to the vertical piece, that is, the guide portion 4121 is opened outward, so that the entrance ends of the two lower pocket opening paddles 412 are trumpet-shaped, so as to facilitate the feeding of folded fabrics.

[0067] When the bag-stretching assembly 41 is used in the first embodiment, the bag-blowing assembly 43 first presses the sealing part of the fabric plastic bag 100, and after the bag-blowing assembly 43 blows up the fabric plastic bag 100, the two swing lower supports 415 control the lower paddles 412 and the upper paddles 413 to rotate outward, so that the lower paddles 412 and the upper paddles 413 extend from the middle of the bag opening of the fabric plastic bag 100 into the fabric plastic bag 100, and when the lower paddles 412 and the upper paddles 413 rotate to be in axial balance with the fabric plastic bag 100, the bag opening is stretched open, and the bag opening is tightened by the tensioning cylinder 44 to facilitate the feeding of fabric. When the first embodiment is used, the width and height of the bag opening are slightly larger than the width and height of the folded fabric, respectively, to facilitate the feeding of fabric.

[0068] When the bag-stretching assembly 41 is used in the second embodiment, the sealing portion of the fabric plastic bag 100 is first pressed by the bag-blowing assembly 43. After the bag-blowing assembly 43 blows up the fabric plastic bag 100, the lower swinging support 415 controls the lower bag-opening paddle 412 and the upper bag-opening paddle 413 to rotate outward, so that the lower bag-opening paddle 412 and the upper bag-opening paddle 413 extend into the fabric plastic bag 100 from the middle of the bag opening of the fabric plastic bag 100, and the bag opening is tensioned by the tensioning cylinder 44. At this time, the bag opening is stretched to a first height and a first width, wherein the first width is slightly smaller than the width of the fabric after folding, and the first height is higher than the thickness of the fabric to be packaged. The fabric to be packaged can be smoothly fed into the mouth of the fabric plastic bag 100 by using the guiding portion of the lower bag-opening paddle 412. At this time, the two sides of the portion of the fabric to be packaged that is fed into the fabric plastic bag 100 will be slightly tilted. After the bag-stretching assembly 41 detects that the fabric to be packaged has been fed into the fabric plastic bag 100 by a preset distance, the upper paddle lifting motor 414 controls the bag-opening upper paddle 413 to descend to a second height, and at the same time, the bag opening is kept in a tensioned state by the tensioning cylinder 44, so that the bag opening is stretched to a second width. At this time, the second height is smaller than the first height, and the second width is larger than the first width, so that the fabric to be packaged will not curl on both sides after all the fabrics to be packaged are fed into the fabric plastic bag 100. Compared with the first embodiment, the second embodiment can use a smaller fabric plastic bag 100 to package fabrics of the same size (such as clothes), and the fabrics can be fuller and more beautiful after packaging, that is, the packaging is tight, so that the fabrics occupy less space after packaging.

[0069] The bag support assembly 41 further includes a rotation-stopping guide rod 418, which is fixed to the nut seat 4141 of the upper paddle lifting motor 414 and can be lifted and lowered relative to the bag opening base 411, ensuring that the nut seat 4141 of the upper paddle lifting motor 414 drives the swing upper support 416 to perform lifting and lowering movements. Furthermore, the bag support assembly 41 further includes a feeding detector (not shown in the figure), which is used to detect when the fabric to be packaged is fed into the fabric plastic bag 100 to a preset length, such as when the fabric to be packaged is fed into the fabric plastic bag 100 to a quarter of the length, so that the upper paddle lifting motor 414 controls the bag opening upper paddle 413 to descend to a second height.

[0070] The plastic bag opening device 4 also includes a bag opening detector (not shown in the figure) and an alarm (not shown in the figure) for detecting whether the bag opening is successful. The bag opening detector is arranged on the tensioning cylinder 44 and is used to detect the stroke of the active end of the tensioning cylinder 44. When the stroke exceeds a preset value, it is determined that the bag opening fails, and the alarm is sounded. The bag opening detector can be a stroke detection sensor on the tensioning cylinder 44, or a position detection sensor added to the tensioning cylinder 44. During operation, the bag opening is opened by the upper paddle 413 and the lower paddle 412, and then the bag opening of the fabric plastic bag 100 is kept in a tensioned state by the tensioning cylinder 44, at which time the bag opening serves to limit the extension length of the tensioning cylinder 44; when the upper paddle 413 and the lower paddle 412 do not extend into the bag opening of the fabric plastic bag 100, the tensioning cylinder 44 is not limited, and the telescopic rod of the tensioning cylinder 44 will extend all the way to the bag opening detector, and it is determined that the bag opening fails. It is very likely that the plastic bag holding device 4 does not hold the bag, and the alarm is sounded. Of course, the present invention can also be set to perform a second bag opening operation after the first bag opening fails. When the second bag opening operation also fails, the alarm is sounded and waits for the staff to handle it.

[0071] Please also read Fig.17 and Fig.18The bag width adjustment assembly 42 includes a motor 421, a synchronous shaft 422, a synchronous slider 423, a first synchronous belt 424, a second synchronous belt 425, two positioning blocks 426 and a cylinder mounting plate 427. The synchronous shaft 422 is connected to the output shaft of the motor 421 through the first synchronous belt 424. The synchronous slider 423 is sleeved on the synchronous shaft 422 and fixed to the cylinder mounting plate 427. The positioning block 426 is arranged on the second synchronous belt 425. Each of the bag opening bases 411 is fixed to a positioning block 426. The tensioning cylinder 44 is fixed to the cylinder mounting plate 427, and the movable end of the tensioning cylinder 44 is connected to the positioning block 426. Specifically, one positioning block 426 is fixed to one side of the second synchronous belt 425, and the other positioning block 426 is fixed to the same side of the second synchronous belt 425, so that when the second synchronous belt 425 rotates, the two positioning blocks 426 move relative to or oppositely. When adjusting the spacing between the two bag-supporting assemblies 41, the motor 421 drives the synchronous shaft 422 to rotate via the first synchronous belt 424, so that the synchronous slider 423 mounted on the synchronous shaft 422 moves, and the cylinder mounting plate 427 fixed to the synchronous slider 423 and the tensioning cylinder 44 on the cylinder mounting plate 427 move synchronously. Since the movable end of the tensioning cylinder 44 is connected to one of the positioning blocks 426, the second synchronous belt 425 is driven to rotate when the synchronous slider 423 moves, so that the two bag-opening bases 411 fixed on the second synchronous belt 425 move toward or oppositely, thereby adjusting the spacing between the two bag-supporting assemblies 41. After the spacing of the bag-supporting assembly 41 is adjusted, the motor 421 stops rotating, and the synchronous slider 423 remains in position on the synchronous shaft 422. When the bag-supporting assembly 41 opens the bag opening, the tensioning cylinder 44 is started, and its movable end pushes one of the positioning blocks 426 (the position of the bag-supporting assembly 41 is controlled by the positioning block 426). Since the positioning blocks 426 are fixed on the second synchronous belt 425, when one of the positioning blocks 426 moves, the second synchronous belt 425 moves synchronously, causing the other positioning block 426 to move in the opposite direction, thereby achieving the purpose of tensioning the bag opening of the fabric plastic bag 100.

[0072] Furthermore, the bag width adjustment component 42 also includes an auxiliary slide rail 45 and an auxiliary slider 46. The cylinder mounting seat 441 and the positioning block 426 are both slidably set on the auxiliary slide rail 45 through the auxiliary slider 46, so that the motor 421 drives the cylinder mounting seat 441 and the positioning block 426 to move more smoothly, and can also reduce the load of the motor 421 and the second synchronous belt 425 to extend the service life of the bag width adjustment component 42.

[0073] Please continue reading Fig.13The bag blowing assembly 43 includes a bag opening blowing plate 431 and a bag opening blowing nozzle 432. The air inlet ends of the bag opening blowing plate 431 and the bag opening blowing nozzle 432 are connected to an external air supply device. The bag opening blowing plate 431 is arranged at the front end of the bag opening lower paddle 412, and the bag opening blowing nozzle 432 is arranged at the rear side of the bag opening lower paddle 412. Before the bag is inflated, the bag opening blowing plate 431 of the bag blowing assembly 43 presses the sealing part of the fabric plastic bag 100, and then the bag opening blowing plate 431 blows air to open the bag mouth of the fabric plastic bag 100, and then the bag opening lower paddle 412 and the bag opening lower paddle 412 rotate outward to open the bag mouth, and at the same time, the bag opening blowing nozzle 432 blows air to inflate the entire fabric plastic bag 100 to Fig.12 The state shown is convenient for feeding the fabric to be packaged.

[0074] Based on the above-mentioned plastic bag holding device 4, the present invention also provides a bag holding and bagging method of the above-mentioned plastic bag holding device 4. In a first optional embodiment, the bag holding and bagging method comprises the following steps:

[0075] The bag width adjustment component 42 adjusts the distance between the two bag support components 41 according to the width of the folded fabric;

[0076] The bag opening and blowing plate 431 of the bag blowing assembly 43 presses the sealing portion of the fabric plastic bag 100, and then the bag blowing assembly 43 blows air to open the bag opening of the fabric plastic bag 100, and the bag support assembly 41 rotates outward to extend into the fabric plastic bag 100 and open the bag opening;

[0077] The tensioning cylinder 44 is operated to move the two bag width adjustment components 42 so that the bag openings are continuously kept in a tensioned state, which is convenient for feeding the fabric.

[0078] When the tensioning cylinder 44 detects that the bag opening fails, the bag opening operation can be repeated or an alarm can be sounded by an alarm, waiting for the staff to handle.

[0079] In a second optional embodiment, the bag-holding and bag-filling method comprises the following steps:

[0080] The bag width adjustment component 42 adjusts the distance between the two bag support components 41 according to the width of the folded fabric;

[0081] The bag opening and blowing plate 431 of the bag blowing assembly 43 presses the sealing part of the fabric plastic bag 100, and then the bag blowing assembly 43 blows air to open the bag opening of the fabric plastic bag 100, and the bag opening assembly 41 rotates outward to extend into the fabric plastic bag 100 and opens the bag opening to a first height, and at the same time, opens the bag opening to a first width, and the first width is smaller than the width of the fabric, and the bag opening is tightened by the tensioning cylinder 44, and the fabric can be easily fed in by using the guide part of the bag opening lower paddle 412;

[0082] When it is detected that the fabric to be packaged is fed into the fabric plastic bag 100 and the preset length of the front end of the fabric is fed into the fabric plastic bag 100 to be packaged, the bag opening component 41 lowers the opening height of the bag to a second height, and the tensioning cylinder opens the bag to a second width and keeps the bag tensioned; wherein the first height is greater than the second height, and the first width is less than the second width;

[0083] The tensioning cylinder 44 operates to move the two bag width adjustment components 42 so that the bag opening is kept in a tensioned state. When the bag opening component 41 lowers the bag opening to the second height, the tensioning cylinder 44 keeps the bag opening in tension, even if the bag opening is opened to the second width, so that the fabric is easily fed in and the corners will not fold. When the tensioning cylinder 44 detects that the bag opening fails, the bag opening operation can be repeated or the alarm can be sounded for the staff to handle. In this way, the packaged fabric is fuller and more beautiful.

[0084] Both of the above two embodiments can complete the bag opening and bag expansion operations of the fabric plastic bag 100. The specific method can be selected according to the size ratio of the fabric plastic bag 100 and the fabric to achieve the best packaging effect. Since the two bag opening methods have been described in detail above, they will not be repeated here.

[0085] Please also read Fig.17 and Fig.18The bag width adjustment assembly 42 includes a motor 421, a synchronous shaft 422, a synchronous slider 423, a first synchronous belt 424, a second synchronous belt 425, two positioning blocks 426 and a cylinder mounting plate 427. The synchronous shaft 422 is connected to the output shaft of the motor 421 through the first synchronous belt 424. The synchronous slider 423 is sleeved on the synchronous shaft 422 and fixed to the cylinder mounting plate 427. The positioning block 426 is arranged on the second synchronous belt 425. Each of the bag opening bases 411 is fixed to a positioning block 426. The tensioning cylinder 44 is fixed to the cylinder mounting plate 427, and the movable end of the tensioning cylinder 44 is connected to the positioning block 426. Specifically, one positioning block 426 is fixed to one side of the second synchronous belt 425, and the other positioning block 426 is fixed to the same side of the second synchronous belt 425, so that when the second synchronous belt 425 rotates, the two positioning blocks 426 move relative to or oppositely. When adjusting the spacing between the two bag-supporting assemblies 41, the motor 421 drives the synchronous shaft 422 to rotate via the first synchronous belt 424, so that the synchronous slider 423 mounted on the synchronous shaft 422 moves, and the cylinder mounting plate 427 fixed to the synchronous slider 423 and the tensioning cylinder 44 on the cylinder mounting plate 427 move synchronously. Since the movable end of the tensioning cylinder 44 is connected to one of the positioning blocks 426, the second synchronous belt 425 is driven to rotate when the synchronous slider 423 moves, so that the two bag-opening bases 411 fixed on the second synchronous belt 425 move toward or oppositely, thereby adjusting the spacing between the two bag-supporting assemblies 41. After the spacing of the bag-supporting assembly 41 is adjusted, the motor 421 stops rotating, and the synchronous slider 423 remains in position on the synchronous shaft 422. When the bag-supporting assembly 41 opens the bag opening, the tensioning cylinder 44 is started, and its movable end pushes one of the positioning blocks 426 (the position of the bag-supporting assembly 41 is controlled by the positioning block 426). Since the positioning blocks 426 are fixed on the second synchronous belt 425, when one of the positioning blocks 426 moves, the second synchronous belt 425 moves synchronously, causing the other positioning block 426 to move in the opposite direction, thereby achieving the purpose of tensioning the bag opening of the fabric plastic bag 100.

[0086] Furthermore, the bag width adjustment component 42 also includes an auxiliary slide rail 45 and an auxiliary slider 46. The cylinder mounting seat 441 and the positioning block 426 are both slidably set on the auxiliary slide rail 45 through the auxiliary slider 46, so that the motor 421 drives the cylinder mounting seat 441 and the positioning block 426 to move more smoothly, and can also reduce the load of the motor 421 and the second synchronous belt 425 to extend the service life of the bag width adjustment component 42.

[0087] Please continue reading Fig.13The bag blowing assembly 43 includes a bag opening blowing plate 431 and a bag opening blowing nozzle 432. The air inlet ends of the bag opening blowing plate 431 and the bag opening blowing nozzle 432 are connected to an external air supply device. The bag opening blowing plate 431 is arranged at the front end of the bag opening lower paddle 412, and the bag opening blowing nozzle 432 is arranged at the rear side of the bag opening lower paddle 412. Before the bag is inflated, the bag opening blowing plate 431 of the bag blowing assembly 43 presses the sealing part of the fabric plastic bag 100, and then the bag opening blowing plate 431 blows air to open the bag mouth of the fabric plastic bag 100, and then the bag opening lower paddle 412 and the bag opening lower paddle 412 rotate outward to open the bag mouth, and at the same time, the bag opening blowing nozzle 432 blows air to inflate the entire fabric plastic bag 100 to Fig.12 The state shown is convenient for feeding the fabric to be packaged.

[0088] See also Fig.19 The rubber bag peeling and sealing device 5 comprises a rubber sandwich component 51 for clamping the rubber strip 100, a rubber sandwich lifting component 52 for controlling the lifting and lowering of the rubber sandwich component 51, a rubber sandwich translation component 53 for tearing off the rubber strip, and a sealing component 54 for sealing the rubber bag after tearing off the rubber strip. During the peeling process, the rubber sandwich lifting component 52 first controls the rubber sandwich component 51 to descend and press the bonding part of the rubber bag, so that one side of the rubber strip 101 is tilted and the edge of one side of the rubber strip 101 is clamped. Figure 1 The dotted area is pressed down, causing the right side of the rubber strip to tilt up. After the rubber strip 100 is clamped, the rubber sandwich lifting assembly 52 causes the rubber sandwich assembly 51 to rise to a set height to avoid the rubber sandwich position, and the rubber sandwich translation assembly 53 controls the rubber sandwich assembly 51 to translate and tear the rubber, and then the sealing assembly 54 seals the plastic bag. The present invention can reliably tilt one side of the rubber strip 101 by pressing down the bonding part of the plastic bag without shaking, so that the rubber strip can be reliably clamped, and the step of translational tearing of the rubber can simulate the effect of manual parallel tearing of the rubber. Compared with the existing tearing device, after clamping the rubber strip, the rubber strip 100 is lifted and the rubber is vertically torn. The translational tearing method of the present invention can reduce the pulling of the bonding part of the plastic bag during the tearing process, and can avoid deformation of the bonding part of the plastic bag to ensure the flatness of the mouth of the plastic bag after sealing.

[0089] Please also read Figure 20 to Figure 22 The clamping assembly 51 includes a clamping plate 511, a clamping claw 512 and a clamping claw cylinder 513. The clamping claw 512 is arranged opposite to the clamping plate 511. The clamping claw cylinder 513 is connected to the clamping claw 512 to control the opening and closing of the clamping claw 512 relative to the clamping plate 511. The bottom of the clamping plate 511 is lower than the preset height of the clamping claw 512. The preset height is used to press the fitting part of the plastic bag (such as Figure 3 The dotted line area) causes the rubber strip to tilt up, and then the clamping jaw 512 and the clamping plate 511 are closed by the clamping jaw cylinder 513 to clamp one side of the rubber strip in preparation for subsequent rubber tearing. In addition, the clamping jaw 512 is also provided with anti-slip grooves to make it less likely to fall off when clamping the rubber strip.

[0090] Furthermore, the glue-clamping assembly 51 includes a platform 514, and the platform 514 has a groove (i.e., a glue-clamping position), and an elastic lifting plate 5141 is arranged in the groove (not numbered in the figure), and the descending depth of the elastic lifting plate 5141 is greater than or equal to the preset height, so as to ensure that when the clamping plate 511 is pressed down, the elastic lifting plate 5141 descends and presses the fitting part of the plastic bag, so that one side of the rubber strip stands up, and at the same time, the bottom of the clamping jaw 512 can be close to the platform 514, thereby ensuring that the rubber strip can be clamped when the clamping jaw 512 is closed (such as Fig.21 When the glue clamping lifting assembly 52 rises to a set height to avoid the glue clamping position, the elastic lifting plate 5141 is reset.

[0091] Please continue reading Figures 19 to 22 The laminated lifting assembly 52 includes a laminated lifting cylinder 521, a lifting control rod 522, a positioning frame 523, a positioning plate 524, a lifting rod 525 and a lifting spring 526. The movable end of the laminated lifting cylinder 521 and one end of the lifting control rod 522 pass through the positioning frame 523 and are connected to the clamping plate 511. One end of the lifting rod 525 and the other end of the lifting control rod 522 are connected to the positioning plate 524. The lifting spring 526 is sleeved on the lifting rod 525 (as shown in FIG. Fig. 20 When the rubber strip 101 is sandwiched, the positioning plate 524 and the clamping plate 511 are lowered, causing the elastic lifting plate 5141 to move down to the sandwiching position, so that one side of the rubber strip 101 is tilted. At this time, the lifting rod 525 abuts against the positioning frame 523 to compress the lifting spring 526 (as shown in FIG. Fig.21 As shown), the clamping claw 512 can be controlled to move toward the side of the clamping plate 511 to clamp the raised rubber strip 101. Afterwards, when the clamping lifting cylinder 521 stops supplying air, the lifting spring 526 is reset to make the clamping plate 511 rise to the set height, avoiding the platform 514, so as to facilitate translational tearing of the rubber.

[0092] In this embodiment, the lifting control rod 522 and the lifting rod 525 are both two, which are arranged on both sides of the laminated lifting cylinder 521, so that the laminated lifting assembly 52 controls the lifting of the laminated assembly 51 more smoothly. The specific operation of the laminated lifting assembly 52 is as follows: first, the laminated lifting cylinder 521 moves downward to make the clamping plate 511 descend. Since one end of the lifting control rod 522 is connected to the clamping plate 511 and the other end is connected to the positioning plate 524, when the clamping plate 511 descends, the positioning plate 524 is driven to descend synchronously through the lifting control rod 522. When the clamping plate 511 descends and causes the elastic lifting plate 5141 to descend to the position of the laminated strip, the lifting rod 525 abuts against the positioning frame 523. At this time, the lifting rod 525 is lifted and lowered. The lifting spring 526 is compressed, and its compressed length is the height to which the elastic lifting plate 5141 descends. After the clamping claw 512 clamps the rubber strip, the rubber-laminating lifting cylinder 521 stops supplying air (since the rubber-laminating lifting cylinder 521 does not have reverse ventilation, the rubber-laminating lifting cylinder 521 maintains the current state unchanged), and the lifting spring 526 is reset to make the clamping plate 511 rise and separate from the elastic lifting plate 5141, that is, to leave the rubber-laminating position, and then the rubber-laminating translation component 53 controls the translation of the rubber-laminating component 51 (such as Fig. 22 The purpose of removing the glue is achieved.

[0093] Specifically, the laminated translation assembly 53 includes a laminated support frame 531, a slider 532, a slide rail 533 and a translation cylinder 534. The slider 532 is arranged on both sides of the laminated support frame 531. The slide rail 533 is slidably connected to the slider 532. The positioning frame 523 connects one end of the two slide rails 533. The translation cylinder 534 is fixed on the laminated support frame 531. The movable end of the translation cylinder 534 is connected to the middle of the positioning frame 523. The laminated lifting assembly 52 is arranged on the positioning frame 523. During the translation process, the movement positions of the laminated lifting assembly 52 and the laminated assembly 51 are controlled by the extension and contraction of the translation cylinder 534. At the same time, the movement of the laminated lifting assembly 52 is more stable and reliable through the cooperation between the slide rail 533 and the slider 532.

[0094] like Figures 19 to 22As shown, the plastic bag glue tearing and sealing device 5 also includes a bag mouth pressing assembly 55 for pressing the mouth of the plastic bag. The bag mouth pressing assembly 55 is arranged opposite to the glue clamping assembly 51. The bag mouth pressing assembly 55 includes a bag mouth pressing plate 551 and a bag mouth pressing cylinder 552. The movable end of the bag mouth pressing cylinder 552 is connected to the bag mouth pressing plate 551. The bag mouth pressing assembly 55 is arranged on the glue clamping support frame 531. When the glue strip is clamped, the bag mouth pressing cylinder 552 controls the bag mouth pressing plate 551 to descend to press the bag mouth of the plastic bag. Then, the glue clamping lifting assembly 52 controls the clamping plate 511 to descend to press the bonding part of the plastic bag, which can help one side of the glue strip to tilt up. When the clamping claw 512 clamps the glue strip and rises to leave the glue clamping position, the bag mouth pressing plate 551 is always in the state of pressing the plastic bag. Then, the glue clamping translation assembly 53 moves, and the purpose of glue tearing can be achieved. It can be seen that the bag opening pressing assembly 55 can ensure the normal operation of glue sandwiching and glue tearing.

[0095] The plastic bag glue tearing and sealing device 5 also includes a glue strip recovery component 56, which is arranged on the glue tearing moving side of the glue clamping component 51. The glue strip recovery component 56 includes a glue strip recovery port 561, and the glue strip recovery port 561 is connected to a compressed air source (not shown in the figure). After the glue clamping component 51 clamps the glue strip, the glue clamping translation component 53 moves along the front side of the bag opening to separate the glue strip from the plastic bag. When it moves to the recovery port, the compressed air generates negative pressure to suck in the glue strip, thereby achieving the purpose of recovering the glue strip, avoiding the glue strip from spilling and causing environmental pollution, and avoiding affecting subsequent packaging.

[0096] Please continue reading Fig.19 , Fig.23 and Fig.24 The sealing component 54 includes a plastic bag pressing unit 541 and a sealing unit 542. The plastic bag pressing unit 541 is arranged at the rear side of the sandwich component 51, and the sealing unit 542 is arranged between the plastic bag pressing unit 541 and the sandwich component 51. After the air in the plastic bag is emptied by pressing down the plastic bag pressing unit 541, the plastic bag pressing unit 541 cooperates with the sealing unit 542 to stick the pasted part of the torn plastic strip, and the fabric packaging is completed.

[0097] The plastic bag pressing unit 541 includes a plastic bag pressing support frame 5411, a bag body pressing cylinder 5412, a bag mouth baffle 5413, a bag mouth leveling plate 5414, an exhaust cylinder 5415 and an exhaust pressure plate 5416. The bag body pressing cylinder 5412 is arranged on the plastic bag pressing support frame 5411, the bag mouth baffle 5413 is connected to the movable end of the bag body pressing cylinder 5412, the bag mouth leveling plate 5414 is arranged on the bag mouth baffle 5413, and the exhaust cylinder 5415 is arranged on the bag mouth baffle 5413. Placed on the plastic bag pressing support frame 5411, the exhaust pressure plate 5416 is connected to the movable end of the exhaust cylinder 5415, and the exhaust cylinder 5415 presses down to make the exhaust pressure plate 5416 press the plastic bag to exhaust the air in the plastic bag, and then the bag body pressing cylinder 5412 presses down to make the bag opening baffle 5413 press against the part of the fitting part of the plastic bag that needs to be folded, and at the same time, the bag opening leveling plate 5414 presses the bag opening of the plastic bag to achieve the effect of leveling the bag opening, so that the sealing unit 542 can seal the plastic bag.

[0098] The sealing unit 542 includes a sealing flap 5421, a flap lifting cylinder 5422, a flap lifting frame 5423, a flip cylinder 5424 and a flip connecting rod 5425. The movable end of the flap lifting cylinder 5422 is connected to the flap lifting frame 5423, the flip cylinder 5424 is arranged on the flap lifting frame 5423, one end of the flip connecting rod 5425 is connected to the movable end of the flip cylinder 5424, and the other end of the flip connecting rod 5425 is connected to the sealing flap 5421. When the plastic bag is sealed, the bag mouth baffle 5413 presses against the folded part of the fitting part of the plastic bag, and the flap lifting cylinder 5422 controls the flap lifting frame 5423 to rise and the sealing flap 5421 to rise synchronously, so that the fitting part of the plastic bag that needs to be folded stands up, and then rises through the bag body pressing cylinder 5412, so that the bag mouth leveling plate 5414 and the bag mouth baffle 5413 leave the plastic bag, and then the turning cylinder 5424 operates, and the sealing flap 5421 is turned over through the turning connecting rod 5425, so that the part with adhesive is fitted with the bag mouth of the plastic bag, and the sealing operation is completed.

[0099] The conveying device 6 is a conveyor belt structure, which is more convenient for fabric conveying. Since this structure is prior art, it will not be described in detail here.

[0100] The plastic bag glue tearing and sealing device 5 also includes a detection component for detecting the position of the plastic bag (such as a photoelectric sensor, a camera, etc., for identifying the position of the identification line, and then controlling the stop position of the conveying device 6 according to the detection result). The conveying device 6 and the detection component can ensure that the plastic bag is delivered to the specified position, and then other components can complete the specified action. The present invention can also use a progressive motor to drive the conveying device 6 to rotate and convey the plastic bag 100. Therefore, the present invention can also control the conveying position of the plastic bag 100 by controlling the rotation angle of the progressive motor, thereby accurately controlling the glue sandwiching and bag sealing position.

[0101] In order to make the technical solution of the plastic bag peeling and sealing device 5 clearer, the following is combined with Figures 1 to 7 The working method of the plastic bag peeling and sealing device 5 is described in detail:

[0102] When performing the glue-laminating action, the detector first detects the position of the identification line 102 on the plastic bag 100 to locate the position of the rubber strip 101, and controls the transmission state of the transmission device according to the detection result. When the rubber strip reaches the groove of the platform 514, the bag mouth pressing component 55 first presses the bag mouth of the plastic bag, and then the glue-laminating lifting component 52 controls the glue-laminating component 51 to descend. At this time, the clamping plate 511 presses the elastic lifting plate 5141 to descend and press the bonding part of the plastic bag 100 so that the height of the bonding part is lower than the part of the rubber strip that is not pressed, that is, one side of the rubber strip is tilted by pressing down a part of the rubber strip and the bonding part, and then the clamping cylinder of the clamping jaw 512 controls the clamping jaw 512 to clamp one side of the rubber strip. Compared with the method of tilting the rubber strip by blowing air, this method does not shake when the rubber strip is tilted, so that the clamping jaw clamping is more reliable.

[0103] After the clamping jaws 512 are tightened with the rubber strip, the clamping lifting cylinder 521 stops supplying air, and the lifting spring 526 is reset to make the clamping plate 511 rise and separate from the elastic lifting plate 5141, that is, to leave the height of the clamping position.

[0104] Then, the rubber sandwiching translation assembly 53 controls the rubber sandwiching assembly 51 to translate, so as to achieve the effect of removing the rubber. When the rubber sandwiching translation assembly 53 controls the clamping claw 512 to move to the rubber strip recovery assembly 56, the rubber strip is sucked back through the rubber strip recovery port 561, so as to achieve the purpose of rubber strip recovery.

[0105] Then, the plastic bag is conveyed to the sealing assembly 54 via the conveying device 6, and the exhaust cylinder 5415 presses down, so that the exhaust pressure plate 5416 presses the plastic bag to exhaust the air in the plastic bag, and then the bag body pressing cylinder 5412 presses down, so that the bag opening baffle 5413 presses against the part of the plastic bag that needs to be folded. At the same time, the bag opening leveling plate 5414 presses the bag opening of the plastic bag to achieve the effect of leveling the bag opening, so that the sealing unit 542 can seal the plastic bag.

[0106] Finally, the bag mouth baffle 5413 presses against the folded part of the fitting part of the plastic bag, and the flap lifting cylinder 5422 controls the flap lifting frame 5423 to rise and the sealing flap 5421 to rise synchronously, so that the fitting part of the plastic bag is erected, and then the bag body pressing cylinder 5412 rises to separate the bag mouth leveling plate 5414 and the bag mouth baffle 5413 from the fitting part of the plastic bag, and finally the turning cylinder 5424 operates to turn the sealing flap 5421 through the turning connecting rod 5425, so that the part with adhesive is fitted with the fitting part of the plastic bag, and the sealing operation is completed.

[0107] After the above steps, the plastic bag peeling and sealing operations are completed. The whole process does not require manual operation and is automated.

[0112] The folded fabric is clamped by the clothing clamping device 3 and is sent into the opened fabric plastic bag 100;

[0113] The conveying device 6 conveys the fabric plastic bag 100 containing the fabric to the plastic bag adhesive tearing and sealing device 5;

[0114] The plastic bag tearing and sealing device 5 moves the plastic strip of the fabric plastic bag 100 to tear the plastic strip and seal the plastic bag, and the conveying device 6 delivers the sealed fabric plastic bag 100.

[0115] Among them, the steps of folding clothes, clamping clothes, supplying bags and supporting bags are not prioritized, and only need to be completed before the clamping device delivers the folded fabric into the bag mouth. The present invention can control the execution order of the above steps with optimal efficiency.

[0116] In a second optional embodiment, the automatic packaging method includes:

[0117] The folding device 1 folds the fabric into a block and places it on the clamping device 3, while the bag supply device 2 delivers the plastic bag to the bag support device 4;

[0118] The bag-opening device 4 blows air into the fabric plastic bag 100 to open the bag opening, and according to the width and height of the fabric plastic bag 100, the bag opening is opened to a first height, and at the same time, the bag opening is opened to a first width, and the bag opening is kept in a tensioned state;

[0119] The folded fabric is clamped by the clothing clamping device 3 and the front end of the fabric is fed into the opened fabric plastic bag 100, and then the bag-stretching device 4 is lowered to the second height. At the same time, the tensioning cylinder stretches the bag opening to the second width and keeps it tensioned, wherein the first height is greater than the second height and the first width is less than the second width, so that the fabric is easily fed in and no corner folding occurs.

[0120] The conveying device 6 conveys the fabric plastic bag 100 containing the fabric to the plastic bag adhesive tearing and sealing device 5;

[0121] The plastic bag peeling and sealing device 5 performs translational peeling of the plastic strip of the fabric plastic bag 100 and seals the plastic bag, and the sealed fabric plastic bag 100 is delivered by the conveying device 6. In this way, the packaged fabric is fuller and more beautiful.

[0122] Since the structure and working mode of each device have been described in detail above, they will not be repeated here.

[0123] In summary, the automatic clothing packaging machine provided by the present invention realizes the actions of folding fabric, feeding fabric plastic bags, supporting fabric plastic bags, feeding fabric into fabric plastic bags, tearing off the glue of fabric plastic bags and sealing, and the entire process from folding clothes to sealing bags does not require manual participation, and realizes automatic operation. Moreover, when opening the bag mouth, the plastic bag supporting device also adjusts the width and height of the bag mouth of the fabric plastic bag according to the size of the fabric, and tightens the bag mouth, so as to realize the use of a smaller packaging bag to package the fabric, making the packaged fabric fuller and more beautiful.

[0124] Moreover, the bag-holding and bag-filling method of the present invention provides two optional embodiments, and the most suitable method can be selected according to the size ratio of the fabric plastic bag and the fabric, thereby ensuring that the packaged fabric is fuller and more beautiful, and also improving the packaging efficiency and the appearance quality of the product packaging.

[0125] In addition, the invented glue peeling and sealing device can simulate the effect of manual parallel glue peeling, and the translational glue peeling method can reduce the pulling of the adhesive part of the plastic bag during the glue peeling process, and can avoid deformation of the adhesive part of the plastic bag to ensure the flatness of the mouth of the plastic bag after sealing. Moreover, the glue strip will not shake when it is lifted. Compared with the method of blowing and clamping the glue strip, the invention improves the reliability of the glue peeling operation and has high glue peeling efficiency.

[0126] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all these changes or substitutions should fall within the protection scope of the claims attached to the present invention.
