[0045] Referring to Figures 1 to 4 In some embodiments, the present application provides a full-automatic packaging device of flexible packaging material, comprising:

[0046] mounting base 1;

[0047] material conveying device 2, provided on the mounting base 1, comprising a first conveying section 21 and a second conveying section 22 arranged horizontally and spaced apart, a first channel being formed between the first conveying section 21 and the second conveying section 22, the first channel being provided for the flexible packaging material to pass through, the first conveying section 21 and the second conveying section 22 being used for conveying the product to be packaged;

[0048] feeding device 3, provided on the mounting base 1 and located above the material conveying device 2, an outlet end of the feeding device 3 being arranged towards the first channel, the feeding device 3 being used for carrying the material and conveying the flexible packaging material to the first channel;

[0049] pulling mechanism 4, provided on the mounting base 1 and located below the material conveying device 2, the pulling mechanism 4 being capable of passing through the first channel to grab the flexible packaging material and driving the grabbed flexible packaging material to move;

[0050] cutting device 5, provided between the material conveying device 2 and the outlet end of the feeding device 3, and used for cutting the flexible packaging material.

[0051] In this embodiment, the full-automatic packaging device for flexible packaging material of the present application can be applied in a clothes folding equipment, the material conveying device 2 can convey clothes as the product to be packaged, and the flexible packaging material can be paper or film covering the clothes, which are only exemplary.

[0052] The material conveying device 2 conveys the product to be packaged through the first conveying section 21 and the second conveying section 22 arranged horizontally and spaced apart on the mounting base 1, and meanwhile utilizes the first channel formed between the two, the first channel being provided for the flexible packaging material to pass through, thereby providing a basis for subsequently covering the flexible packaging material on the product to be packaged.

[0053] The feeding device 3 is provided on the mounting base 1 and located above the material conveying device 2, and its outlet end is arranged towards the first channel, and it is capable of continuously providing the flexible packaging material required for the packaging operation by virtue of its function of carrying the material and conveying the flexible packaging material to the first channel. Exemplarily, the feeding device 3 can be a conveying line or a multi-axis carrying robot, which is not limited here.

[0054] The pulling mechanism 4 is located below the material conveying device 2 and can grasp and drive the flexible packaging material to move. Specifically, in the initial state, the pulling mechanism 4 is first in a standby state and is located in an initial position below the material conveying device 2, waiting for the feeding device 3 to convey the flexible packaging material above the first channel, and is ready for the grasping operation. When the flexible packaging material reaches the designated area, the pulling mechanism 4 starts the corresponding grasping component (for example, by mechanical clamps 42, suction devices, etc., depending on the design structure, which is only exemplarily described here), contacts and grasps the flexible packaging material through the first channel. After successful grasping, the pulling mechanism 4 drives the grasped flexible packaging material to move according to the preset packaging program instructions. For example, according to the length of the product and the packaging requirements, the flexible packaging material is pulled in the direction towards the initial position to reach the appropriate length, preparing for subsequent cutting and complete wrapping of the product. After completing this stage of movement, the pulling mechanism 4 maintains the grasping state of the packaging material until the cutting device 5 completes the cutting operation and other subsequent process links.

[0055] When the front end of the product to be packaged reaches the end of the first conveying section 21, the sensor can detect the positioning of the product to be packaged. At this time, the cutting device 5 can accurately control the length of the packaging material and cut it at the appropriate position, and the pulling mechanism 4 releases the cut flexible packaging material. The first conveying section 21 continues to convey the product to be packaged to the second conveying section 22. When the product to be packaged passes through the first channel between the first conveying section 21 and the second conveying section 22, the cut flexible packaging material is driven by the product to be packaged and wrapped on the outside of the product to be packaged, thereby completing the packaging of the packaging material of an independent packaging unit, and finally achieving the full-automatic packaging of the product to be packaged.

[0056] The present application realizes the following advantages by providing the above-mentioned flexible packaging material full-automatic packaging device.

[0057] Advantages:

[0058] First, the packaging efficiency is improved: the entire packaging process is automated, and each device cooperates without excessive human intervention. Compared with traditional manual packaging or semi-automatic packaging methods, more products can be packaged in a unit of time, greatly improving the packaging speed and overall efficiency.

[0059] Second, the packaging quality is improved: the feeding device 3, the pulling mechanism 4, and the cutting device 5 can accurately control the conveying amount, stretching condition, and cutting position of the flexible packaging material, so that the amount of packaging material for each product is appropriate, the wrapping is tightly and regularly, and the quality of the packaging is effectively guaranteed, reducing the problem of product damage caused by improper packaging.

[0060] Third, the packaging flexibility is high, the application can be according to the size, shape and packaging requirements of different products, by adjusting the related parameters (such as conveying speed, tearing length, cutting position, etc.) of each device, flexible to adapt to diversified packaging tasks, the application range is wide.

[0061] Referring to Figure 1 In some embodiments, the first conveying section 21 includes a first conveying belt 211 and a first driving member 212, the output end of the first driving member 212 is drivingly connected to the first conveying belt 211, the first conveying belt 211 is used to carry the product to be packaged, and the first driving member 212 is used to drive the first conveying belt 211 to move so that the product to be packaged moves in the horizontal direction towards the second conveying section 22.

[0062] The second conveying section 22 includes a second conveying belt 221 and a second driving member 222, the output end of the second driving member 222 is drivingly connected to the second conveying belt 221, the second conveying belt 221 is used to carry the product, and the second driving member 222 is used to drive the second conveying belt 221 to move so that the product moves in the horizontal direction away from the first conveying section 21.

[0063] In this embodiment, first, the product to be packaged is placed on the first conveying belt 211 of the first conveying section 21. The first conveying belt 211 provides a stable carrying plane for the product, so that it can be in the right position and wait for the subsequent conveying operation.

[0064] The output end of the first driving member 212 is drivingly connected to the first conveying belt 211. When the first driving member 212 is started, it will transmit power to the first conveying belt 211, so that the first conveying belt 211 starts to move. Since the product is placed on the first conveying belt 211, under the action of friction, the product will move in the horizontal direction along with the movement of the first conveying belt 211 towards the second conveying section 22.

[0065] When the product reaches the end of the first conveying section 21 under the action of the first driving member 212 and the first conveying belt 211, the product will naturally transition to the second conveying belt 221 of the second conveying section 22. The second conveying belt 221 here plays a role in receiving the product, ensuring that the product can be smoothly transferred from the first conveying section 21 to the second conveying section 22.

[0066] The output end of the second driving member 222 is drivingly connected to the second conveying belt 221. After the product is received, the second driving member 222 is started to provide power to the second conveying belt 221, so that it starts to move. The product on the second conveying belt 221 continues to move in the horizontal direction away from the first conveying section 21 under the action of friction. The purpose of this step is to completely convey the product wrapped with packaging material out of the packaging area, to make room for the packaging process of the next product to be packaged.

[0067] Referring to Figure 1 and Figure 2 In some embodiments, the feeding device 3 provided by the embodiments of the present application comprises:

[0068] A mounting frame 31 is arranged on the mounting base 1, and the mounting frame 31 is formed with a second channel for feeding the flexible packaging material;

[0069] A material-carrying roller 32 is arranged on the mounting frame 31 and used for carrying the flexible packaging material;

[0070] A feeding driving member 33 is used to rotate the material-carrying roller to move the flexible packaging material to feed the flexible packaging material to the second channel.

[0071] In the embodiments, the feeding device 3 mainly relies on the carrying function of the material-carrying roller 32 and the power driving of the feeding driving member 33 to realize the feeding of the flexible packaging material. The material-carrying roller 32 serves as a carrier for placing the flexible packaging material, and the feeding driving member 33 provides rotating power for the material-carrying roller 32.

[0072] When the flexible packaging material is a roll-shaped roll paper, the roll-shaped flexible packaging material can be placed on the material-carrying roller 32, or the flexible packaging material can be wound on the material-carrying roller 32. The packaging material moves with the rotation of the material-carrying roller 32, so as to be fed to the second channel of the mounting frame 31.

[0073] The feeding device 3 provided by the above structure of the present application has the following beneficial effects:

[0074] The feeding device 3 can stably provide the flexible packaging material for the packaging process. Through the cooperation of the feeding driving member 33 and the material-carrying roller 32, the packaging material can be fed out at a certain speed and in a certain order, avoiding the interruption or instability of the material supply and ensuring the continuity of the packaging process. The design of the material-carrying roller 32 not only effectively carries the flexible packaging material, but also keeps the material in good condition during the feeding process. Through a reasonable driving mode, the packaging material can be fully utilized, the waste of the material can be reduced, and the production cost can be reduced.

[0075] Referring to Figure 3 In some embodiments, the full-automatic flexible packaging material packaging device provided by the embodiments of the present application further comprises a tensioning device 6 located between the material-carrying roller 32 and the second channel, and the tensioning device 6 is used to tension the flexible packaging material.

[0076] Further, in some embodiments, the tensioning device 6 proposed in the embodiments of the present application comprises a plurality of tensioning shafts 61, which are spaced apart in the horizontal direction, and adjacent two tensioning shafts 61 are staggered in the vertical direction, each tensioning shaft 61 is used for the flexible packaging material to be wound around, so as to tension the flexible packaging material.

[0077] In the above embodiments, the tensioning shaft 61 can also be called a counterweight support, which mainly realizes the tensioning of the flexible packaging material through a plurality of tensioning shafts 61 spaced apart in the horizontal direction and adjacent two tensioning shafts 61 staggered in the vertical direction. When the packaging material is wound around these tensioning shafts 61, due to the position distribution characteristics of the tensioning shafts 61, the packaging material changes direction when passing through each tensioning shaft 61, which makes the packaging material stretched under the action of its own tension and the friction with the tensioning shaft 61, thereby achieving the effect of tensioning. This design utilizes the flexibility and friction principle of the packaging material, and through reasonable layout of the tensioning shafts 61, the material is in a proper tensioning state.

[0078] Before the packaging equipment starts, the flexible packaging material is first drawn out from the carrier roller 32, and then wound around the plurality of tensioning shafts 61 in turn. The packaging material will pass between the tensioning shafts 61 spaced apart in the horizontal direction, and at adjacent tensioning shafts 61, the material will constantly change direction due to the staggered arrangement of the tensioning shafts 61 in the vertical direction.

[0079] With the start of the feeding drive 33 of the feeding device 3, the carrier roller 32 starts to rotate and convey the packaging material. When the packaging material moves between the tensioning shafts 61, due to its own elasticity and the friction with the surface of the tensioning shafts 61, the material will gradually be tensioned in the process of passing through each tensioning shaft 61. This tensioning state will be maintained as the packaging material continues to be conveyed, ensuring that the packaging material output from the tensioning device 6 is always in a suitable tensioning degree, so as to smoothly enter the second channel and be conveyed above the first channel of the material conveying device 2 subsequently.

[0080] The present application achieves the following beneficial effects by setting the tensioning device 6 with the above structure:

[0081] The tensioning device 6 can effectively avoid the relaxation phenomenon of the flexible packaging material during the conveying process. By maintaining the appropriate tensioning degree of the material, the problems of interrupted or uneven feeding caused by material relaxation are prevented, and the stability and reliability of the feeding are improved. The appropriate tensioning degree makes the flexible packaging material more accurately grabbed and operated by the pulling mechanism 4 when it is conveyed to the packaging position. The relaxed packaging material may cause inaccurate grabbing position or wrinkles, deformation and other situations during the packaging process, and the tensioning device 6 can reduce the occurrence of these problems, thereby improving the precision and quality of the packaging.

[0082] Reference Figure 2In some embodiments, the full-automatic packaging device for flexible packaging material further comprises a clamping mechanism 7 arranged on the upper side of the first channel, which comprises:

[0083] a first clamping piece 71 arranged on the mounting frame 31;

[0084] a second clamping piece 72 slidingly connected to the mounting frame 31, which is arranged horizontally spaced apart from the first clamping piece 71;

[0085] a clamping driving piece 73 arranged on the mounting frame 31, the output end of which is connected to the second clamping piece 72;

[0086] The third channel is formed between the first clamping piece 71 and the second clamping piece 72 for the flexible packaging material to pass through, and the clamping driving piece 73 is used to drive the first clamping piece 71 to abut or move away from the second clamping piece 72 to clamp or release the flexible packaging material in the third channel.

[0087] In this embodiment, the clamping mechanism 7 mainly uses the relative movement of the first clamping piece 71 and the second clamping piece 72 to clamp or release the flexible packaging material. The first clamping piece 71 is fixed on the mounting frame 31, and the second clamping piece 72 is slidingly connected to the mounting frame 31 and is driven to move by the clamping driving piece 73. When the clamping driving piece 73 works, it pushes or pulls the second clamping piece 72 to make it approach or move away from the first clamping piece 71. The third channel formed between the first clamping piece 71 and the second clamping piece 72 is used for the flexible packaging material to pass through. When the second clamping piece 72 approaches the first clamping piece 71, they can exert pressure on the packaging material in the channel and use friction to clamp the material; when the second clamping piece 72 moves away from the first clamping piece 71, the pressure disappears and the packaging material can pass freely, thereby achieving the effect of release.

[0088] Before the packaging process starts, the clamping driving piece 73 is in the initial state, and the second clamping piece 72 maintains a certain distance from the first clamping piece 71 to form a third channel, through which the flexible packaging material can pass smoothly. At this time, the clamping mechanism 7 does not exert clamping force on the packaging material.

[0089] When a specific operation is needed to be performed on the flexible packaging material (such as fixing the position of the material during the cutting operation, or preventing the material from moving when adjusting the state of the material, etc.), the clamping drive 73 starts to work. It drives the second clamping member 72 to slide towards the first clamping member 71, and the second clamping member 72 gradually approaches the first clamping member 71. As the distance between the two decreases, the packaging material located in the third channel is squeezed, and when a certain pressure is reached, the packaging material is tightly clamped between the first clamping member 71 and the second clamping member 72. In this state, the position of the packaging material is fixed, and subsequent precise operations can be performed.

[0090] When the specific operation is completed, the clamping drive 73 drives the second clamping member 72 to slide away from the first clamping member 71, and the distance between the first clamping member 71 and the second clamping member 72 gradually increases, and the pressure on the packaging material decreases. When the distance reaches a certain extent, the packaging material is no longer constrained by sufficient friction, and can freely pass through the third channel. At this time, the clamping mechanism 7 has completed the release action, and the packaging material can continue to flow normally in the device and proceed to the next packaging process.

[0091] The present application achieves the following beneficial effects by setting the clamping mechanism 7 as described above:

[0092] The clamping mechanism 7 can accurately fix the position of the flexible packaging material when needed. In critical steps of the packaging process (such as cutting operation), the clamping of the material can prevent it from moving during the force process (such as the action force of the cutting knife), thereby ensuring the accuracy of the cutting position and helping to improve the precision and quality of the packaging.

[0093] Reference Figure 2 In some embodiments, the cutting mechanism proposed in the present application is arranged between the clamping mechanism 7 and the first channel, and includes:

[0094] The first cutting knife 51 and the second cutting knife 52 are horizontally spaced apart and are both slidingly connected to the mounting frame 31. The first cutting knife 51 and the second cutting knife 52 form a fourth channel for the flexible packaging material to pass through.

[0095] The cutting drive 53 is arranged on the mounting frame 31. The output end of the cutting drive 53 is connected to the first cutting knife 51 and the second cutting knife 52, and is used to drive the first cutting knife 51 and the second cutting knife 52 to move towards each other or away from each other, so as to cut the flexible packaging material.

[0096] In this embodiment, the cutting mechanism mainly relies on the relative movement of the first cutter 51 and the second cutter 52 to cut the flexible packaging material. The first cutter 51 and the second cutter 52 are horizontally spaced apart and slidingly connected to the mounting frame 31, and a fourth passage is formed between them for allowing the packaging material to pass through. The cutting drive 53 is mounted on the mounting frame 31, and its output end is connected to the first cutter 51 and the second cutter 52. When the cutting drive 53 operates, it drives the first cutter 51 and the second cutter 52 to move towards each other, so that the two cutters gradually approach each other and use the sharp edges of the cutters to exert a shearing force on the packaging material located in the fourth passage, thereby cutting the material; when the cutters move away from each other, the fourth passage is opened, and the packaging material can pass through normally, preparing for the next cutting.

[0097] When the packaging process is normal, the cutting drive 53 is in the initial state, and the first cutter 51 and the second cutter 52 maintain a certain distance apart to form a fourth passage, through which the flexible packaging material can pass smoothly. At this time, the cutting mechanism does not perform cutting operation on the packaging material.

[0098] When the packaging process reaches the stage where the packaging material needs to be cut (for example, when the packaging material is stretched to the appropriate length, or the product reaches a certain position and needs to be wrapped), the cutting drive 53 starts to work. It drives the first cutter 51 and the second cutter 52 to move towards each other, and the two cutters move towards each other along the mounting frame 31. As the cutters approach each other, the shearing force exerted on the packaging material located in the fourth passage gradually increases. When the cutting edges of the cutters contact and cut into the packaging material, the packaging material is cut under the action of the shearing force. In this process, since the movement of the cutters is precisely controlled by the cutting drive 53, the packaging material can be accurately cut at the desired position.

[0099] After the packaging material is cut, the cutting drive 53 drives the first cutter 51 and the second cutter 52 to move away from each other, so that the two cutters return to the initial spacing distance and reopen the fourth passage. In this way, the subsequent packaging material can continue to pass through the fourth passage, preparing for the next cutting operation.

[0100] Reference Figure 4 In some embodiments, the tearing mechanism includes:

[0101] The base 41 is provided on the mounting seat 1.

[0102] The clamping jaw 42 is slidingly connected to the base 41, and the clamping jaw 42 is provided corresponding to the first passage. The clamping jaw 42 is used to clamp the flexible packaging material.

[0103] The pulling material driving member 43 is arranged on the mounting base 1, and the output end of the pulling material driving member 43 is connected with the clamping jaw 42, so as to drive the clamping jaw 42 to move in the vertical direction, so that the clamping jaw 42 moves through the first channel to the discharging end of the feeding device 3.

[0104] In the embodiment, the pulling material mechanism mainly realizes the grabbing and pulling of the flexible packaging material by driving the clamping jaw 42 to move in the vertical direction through the pulling material driving member 43. The base 41 provides a stable support foundation for the whole mechanism, and the clamping jaw 42 is slidingly connected to the base 41 and can move up and down in the vertical direction under the action of the pulling material driving member 43. The clamping jaw 42 is arranged corresponding to the first channel and can grab the packaging material at a suitable position. When the pulling material driving member 43 works, it transmits power to the clamping jaw 42, so that the clamping jaw 42 rises in the vertical direction and moves through the first channel to the discharging end of the feeding device 3, so as to clamp the flexible packaging material extending from the discharging end of the feeding device 3. After clamping, the pulling material driving member 43 drives the clamping jaw 42 to move in the vertical direction, so that the clamping jaw 42 returns along the original path with the clamped flexible packaging material, and passes through the first channel. In this process, the pulling material driving member 43 can accurately control the movement speed and stroke of the clamping jaw 42, so as to control the movement speed and pulling length of the flexible packaging material.

[0105] After the packaging material is brought into the first channel, the clamping jaw 42 can keep the clamping state of the packaging material according to the specific needs of the subsequent packaging process, wait for further operation instructions (such as keeping clamping when cooperating with the cutting device 5 to perform cutting operation), or release the packaging material according to the set process, and then return to the initial position in the vertical direction under the driving of the pulling material driving member 43, to prepare for the next round of grabbing, pulling and material entering operations, so as to realize the cyclic packaging process.

[0106] Reference Figure 4 In some embodiments, the flexible packaging material full-automatic packaging device provided by the embodiment of the application further comprises:

[0107] The sliding rail 8 is arranged on the base 41.

[0108] The sliding block 9 is slidingly connected to the sliding rail 8, and the clamping jaw 42 is arranged on the sliding block 9.

[0109] In this embodiment, the combination of the slide rail 8 and the slide block 9 provides the precise movement path for the clamping jaw 42. The slide rail 8 is formed with fixed track shape and direction, and the slide block 9 can only slide along the direction defined by the slide rail 8. Since the clamping jaw 42 is installed on the slide block 9, when the pulling driving member 43 drives the clamping jaw 42 to move, the sliding of the slide block 9 on the slide rail 8 can ensure the stable and precise up-and-down movement of the clamping jaw 42 along the predetermined vertical direction, which can improve the accuracy and repeatability of the movement of the clamping jaw 42, so that the up-and-down positions of the clamping jaw 42 can be accurately controlled each time, thereby ensuring the accuracy of the operation of grabbing and pulling the flexible packaging material, and being beneficial to improving the packaging quality and packaging efficiency.

[0110] Further, the application provides a folding equipment, which comprises the full-automatic packaging device of the flexible packaging material, the feeding device and the receiving device according to the above embodiments. The feeding device is connected to the first end of the first conveying section 21, and is used for conveying the product to be packaged to the first conveying section 21. The receiving device is connected to the last end of the second conveying section 22, and is used for receiving the packaged product.
