Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packing machine, in particular to an automatic packaging method of compressible material, an automatic packaging system and a packing line. BACKGROUND

[0002] At present, the compressible materials such as cotton and chemical fibers need to be packed when transported. Taking cotton as an example, when the cotton is packed by using a binding tape, the cotton is compressed by a compression machine, then the binding machine is moved to the position of the compressed cotton to pack the cotton. However, the binding process needs a certain time, which causes the compression machine to be in a suspended state during the binding process, and thus the packing efficiency is low. In order to improve the packing efficiency, a packaging system and a binding method of compressible material are disclosed in Chinese Patent Publication No. CN111959850A, in which a carrier is used to take out the compressed material from the compression machine and bind and pack the compressed material outside the compression machine. Similarly, a packaging system and a packaging method are disclosed in Chinese Patent Publication No. CN112224488A, in which a carrier is also used to take out the compressed material from the compression machine and bind and pack the compressed material outside the compression machine. In order to meet the requirements of transportation, a protective layer (packing film or cloth) is wrapped around the bound goods after the binding process. The "three filaments" (hetero fibers: chemical fibers, silk and hair) in the cotton binding process are representative, which are the key factors that restrict the packing quality. In the actual application process of the above technical solutions, the debris generated by the mutual friction of the binding tapes during the welding of the binding machine can easily fall into the compressed material during the binding process of the binding machine, which causes the pollution of the material and reduces the packing effect. Therefore, how to design a technology that can reduce the pollution of the material caused by the binding to optimize the packing effect is a technical problem to be solved by the present application.

DETAILED DESCRIPTION

[0044] The application will be described in detail below with reference to the accompanying drawings.

[0045] In an embodiment, the application provides an automatic packaging method of compressible materials, comprising:

[0046] The compressible material is placed into a compression packaging machine for compression to form a to-be-bundled material, the to-be-bundled material in a compressed state is taken out from the compression packaging machine by a carrier and transported to a bundling machine, and at least a protective layer is covered on the surface opposite to the connecting part of the to-be-bundled material and the bundling tape before bundling, and then the to-be-bundled material and the protective layer are bundled together by the bundling tape.

[0047] Specifically, the cotton and chemical fiber materials are compressible, so that the compressible material is placed into a compression packaging machine for compression before being bundled and packaged. After the compressible material is compressed by the compression packaging machine, the to-be-bundled material is formed, which can be transported to the bundling machine by the carrier to be bundled by the bundling machine through the bundling tape.

[0048] During the welding of the bundling tape by the bundling head, the bundling head is easy to generate a large amount of debris by rubbing the bundling tape. In order to avoid the debris of the bundling tape entering the to-be-bundled material, at least a protective layer is arranged between the to-be-bundled material and the bundling head before bundling and packaging, so that the protective layer can cover the surface opposite to the bundling head of the to-be-bundled material, and the debris generated by the bundling tape when the two ends of the bundling tape are connected by the bundling head is blocked by the protective layer outside the to-be-bundled material and cannot enter the to-be-bundled material.

[0049] In this way, for the compressible material, the to-be-bundled material is directly taken out by the carrier after being compressed by the compression packaging machine and participates in the subsequent packaging process, thereby improving the efficiency of bundling and packaging.

[0050] Meanwhile, when the baling operation is performed on the material to be baled in the compressed state, the surface opposite to the baling head is shielded and protected by the protective layer before the material to be baled is baled by the baling belt, so that the debris generated during the connection of the baling belt is prevented from entering the material to be baled. For the protective layer, it covers the protective layer on at least the surface of the material to be baled parallel to the compression direction, so that the connection part of the baling belt is shielded by the protective layer, thereby improving the quality of the package.

[0051] For the protective layer, since it is attached to shield the baling head on at least the non-compression surface of the material to be baled, it is more convenient to attach the protective layer to the outer exposed material to be baled taken out of the baling machine. Compared with the conventional technology of covering the film on the compressed material before packaging in the baling machine, since the protective layer is attached to the material to be baled taken out of the baling machine before baling, the waiting time for operation at the baling machine can be reduced, and the packaging efficiency can be effectively improved. Similarly, compared with the conventional technology of wrapping the protective layer on the baled goods after taking out of the baling machine, the debris of the baling belt can be effectively prevented from entering the material to be baled, thereby improving the packaging quality.

[0052] For the protective layer, its performance entity can be a protective film or a cloth in the conventional technology, which is not limited and described here.

[0053] In actual use, there are various forms of covering the protective layer on the material to be baled taken out of the baling machine, which are illustrated as follows.

[0054] The first way of covering the protective layer is to cover the protective layer on all the outer surfaces of the material to be baled before the baling operation.

[0055] Specifically, after the material to be baled is output from the baling machine through the carrier, the material to be baled in the carrier will be subjected to the operation of covering the protective layer, and the protective layer will cover and wrap all the outer surfaces of the material to be baled, so that the protective layer is covered on the six surfaces of the material to be baled in the compressed state. In this way, since the material to be baled is completely wrapped by the protective layer during the baling and packaging, the material to be baled is spaced apart from the baling head of the baling machine, so as to prevent the debris of the baling belt from entering the material to be baled.

[0056] In actual operation, the protective layer is covered on at least the top surface and the bottom surface of the material to be baled in the compressed state during the output of the material to be baled from the carrier.

[0057] Specifically, since the to-be-bundled material is taken out from the baling machine by the carrier, the top surface and the bottom surface of the to-be-bundled material are pressed in the carrier due to the influence of the expansion of the compressible material, and the top surface and the bottom surface are the pressure surfaces. Therefore, after the to-be-bundled material is separated from the carrier, the operation of covering the protective layer on the top surface and the bottom surface of the to-be-bundled material can be performed.

[0058] The non-pressure surface of the to-be-bundled material can be covered with the protective layer on the carrier, or the protective layer can be covered after the to-be-bundled material is output from the carrier. This is not limited and described here.

[0059] For example, the protective layer is covered on the surface of the to-be-bundled material in a compressed state during the output process of the to-be-bundled material from the carrier. Alternatively, the film is directly covered on the carrier, and the film covers the surface of the to-be-bundled material during the pushing-out process.

[0060] The second way of covering the protective layer is to cover the protective layer on at least the surface of the to-be-bundled material opposite to the baling machine head before the to-be-bundled material is bundled, and then the to-be-bundled material is bundled and packaged by the bundling machine. After the to-be-bundled material is bundled, the operation of covering the protective layer on the other surface or the whole of the to-be-bundled material is performed.

[0061] Specifically, the protective layer is attached to the outer surface of the bundled material; the protective layer covers all the outer surfaces of the bundled material, or the protective layer covers the outer surfaces of the bundled material except the remaining outer surfaces to which the protective layer is attached.

[0062] Specifically, after the to-be-bundled material is bundled by the bundling belt, the protective layer can be attached to the outer surface of the bundled material, and the material of the protective layer can be the same as that of the protective layer. Finally, the whole surface of the material is wrapped and covered by the protective layer and the protective layer.

[0063] In actual operation, there are various forms of covering the protective layer, for example, a protective bag is sleeved on the outer part of the bundled material to form the protective layer, or the protective layer is attached or wound on the outer part of the bundled material.

[0064] Example two, based on the above example one, in order to realize the automatic packaging method of the compressible material provided in the above example one, as shown in Figure 1 and Figure 2 The application also provides an automatic packaging system, which comprises:

[0065] The conveying assembly 100 comprises a moving seat 101 and a carrier 102, the carrier 102 is arranged on the moving seat 101, and the carrier 102 is provided with an accommodating space configured to accommodate the to-be-bundled material formed after the compressible material is compressed;

[0066] The bundling machine 200 is provided with a packing head 201 for bundling and packing the material to be bundled conveyed by the carrier 102 by using the bundling tape.

[0067] The film coating device 300 is configured to cover the protective layer on the surface opposite to the connection part of the material to be bundled and the bundling tape at least before the material to be bundled is bundled by the bundling machine 200.

[0068] Specifically, in actual use, the automatic packaging system is generally installed on the side close to the baling press 1000 to facilitate the taking out of the compressed material to be bundled from the baling press by the carrier 102 in the handling assembly 100.

[0069] After the carrier 102 takes out the material to be bundled, the material to be bundled is always in a compressed state in the carrier 102. Generally, the top and bottom surfaces of the material to be bundled form the compressed surfaces, and the four sides of the material to be bundled are non-compressed surfaces, so that the protective layer can be easily covered on the non-compressed surfaces of the material to be bundled.

[0070] The carrier 102 transports the material to be bundled to the bundling machine 200, and the film coating device 300 is also arranged at the bundling machine 200. Before the bundling operation by the bundling machine 200, the protective layer is covered on the material to be bundled by the film coating device 300, and the protective layer needs to be covered on at least the surface opposite to the packing head 201 of the material to be bundled.

[0071] After the covering operation of the protective layer by the film coating device 300 is completed, the protective layer and the material to be bundled are bundled and packed together by the bundling machine 200. When the packing head 201 connects the two ends of the bundling tape, the debris generated by the bundling tape is shielded by the protective layer, thereby reducing the debris entering the material to be bundled.

[0072] According to different ways of covering the protective layer on the outside of the material to be bundled before the bundling operation, different film coating devices 300 are used to cover the protective layer. The covering of the protective layer on the outside of the material to be bundled includes: covering the protective layer on all the outer surfaces of the material to be bundled before the bundling operation; and covering the protective layer on at least the surface opposite to the packing head of the material to be bundled before the bundling operation. The covering of the protective layer and the bundling and packing are specifically described below with reference to the drawings.

[0073] In an embodiment, in order to cover the protective layer on at least the surface opposite to the packing head of the material to be bundled before the bundling operation, and then perform the re-wrapping operation on the bundled material as a whole after the bundling operation is completed.

[0074] As shown in Figure 1 and Figure 3 The film coating device 300 includes a protection assembly 1 arranged at the bundling machine 200 and used for conveying a protective layer between the packing machine head 201 and the material to be bundled.

[0075] Specifically, the protection assembly 1 includes a first support frame 11 and a first clamping mechanism 12, the first clamping mechanism 12 includes a first sliding frame 121 and a first clamping jaw 122, the first sliding frame 121 is slidably arranged on the first support frame 11, and the first clamping jaw 122 is used for clamping the protective layer and conveying the protective layer to one side of the packing machine head 201 following the first sliding frame 121; the first support frame 11 is arranged at the bundling machine 200.

[0076] Specifically, in actual use, the carrier frame 102 takes out the material to be bundled compressed in the baling press and moves towards the bundling machine 200, and the protection assembly 1 is arranged at the front side of the bundling machine 200, so that the carrier frame 102 moves to the protection assembly 1 first, and then the protection assembly 1 covers the surface of the material to be bundled opposite to the packing machine head 201 with the protective layer.

[0077] During the covering of the protective layer, the first clamping jaw 122 clamps the protective layer and moves following the first sliding frame 121, and the protective layer moves to between the material to be bundled and the packing machine head 201. After the protective layer is moved into position and covers the material to be bundled, the first clamping jaw 122 releases the protective layer, and then the packing machine head 201 is used for bundling and packaging processing.

[0078] Further, in order to realize automatic supply of the protective layer, the protection assembly 1 includes a first unwinding mechanism 13 arranged on the first support frame 11 and used for unwinding a roll 2000 wound with the protective layer.

[0079] Specifically, after the roll 2000 is unwound, it is cut according to the end face size of the material to be bundled to form a protective layer of appropriate size. After the roll 2000 is unwound by the first unwinding mechanism 13, the first clamping jaw 122 clamps the unwound part of the roll 2000 and cuts it, so that the protective layer is clamped by the first clamping mechanism 12.

[0080] Specifically, the first unwinding mechanism 13 includes a first bearing frame 131, a first unwinding motor 132, a first driving shaft 133 and a first driven shaft 134, the first driving shaft 133 and the first driven shaft 134 are arranged side by side and rotatably arranged on the first bearing frame 131, and the first unwinding motor 132 is in transmission connection with the first driving shaft 133.

[0081] Specifically, the roll material 2000 is supported on the first driving shaft 133 and the first driven shaft 134, and the output protective material of the roll material 2000 is driven by the first driving shaft 133 and guided to the output unwinding, and the unwound protective material is clamped by the first clamping jaw 122 when reaching the set length requirement. The first cutting knife (not marked) is further arranged on the first bearing frame 131, which is used to cut the unwound protective material, so that the output protective layer is clamped on the first clamping mechanism 12.

[0082] In addition, for the case that the packing head 201 of the strapping machine 200 is arranged on the side, correspondingly, the first support frame 11 is vertically arranged, and the first sliding frame 121 is arranged on the first support frame 11 in a slideable manner. In this way, the first clamping jaw 122 clamps the protective layer which depends by gravity and covers the side of the material to be strapping

[0083] Similarly, in order to facilitate the operator to replace the roll material later, the first bearing frame 131 is arranged on the first support frame 11 in a slideable manner. Specifically, the first bearing frame 131 can be driven to rise and fall by a motor through a chain transmission or the like. When it is necessary to replace the roll material, the first bearing frame 131 is lowered by a certain height, thereby facilitating the operator to replace the roll material.

[0084] At the same time, the first sliding frame 121 is also provided with a driving member to drive it to reciprocate, for example, a conventional sliding driving mode such as a cylinder or a motor can be adopted, which is not limited and described here.

[0085] When the strapping machine 200 is used for strapping and packing, the strapping and packing operation can be directly performed on the carrying frame 102. For this purpose, the carrying frame 102 is provided with a first threading space for conveying the strapping belt so that the strapping belt is arranged around the material to be strapping. The moving seat 101 reciprocates between the packing machine and the strapping machine 200.

[0086] Specifically, the carrying frame 102 forms a first threading space for conveying the strapping belt, so that the carrying frame 102 conveys the material to be strapping to the strapping machine 200, and then the protective layer is covered on the corresponding end surface of the material to be strapping on the carrying frame 102 by the protection assembly 1, and then the strapping operation is performed by the strapping machine 200 in cooperation with the first threading space. In order to meet the conveying requirement of the strapping belt, the first threading space can be provided with a first belt groove 1021 and the like to meet the conveying requirement of the strapping belt.

[0087] Alternatively, when the strapping machine 200 is used for strapping and packing, the material to be strapping can be first pushed out from the carrying frame 102 for strapping operation. For this purpose, as shown in FIG. 8, the carrying frame 102 is provided with a second clamping jaw 1222 which is arranged on the carrying frame 102 in a slideable manner. Figures 4-6As shown, the automatic packaging system further comprises a pressing assembly 400, the pressing assembly 400 comprising a mounting frame 401, two pressing components 402 and a driving component 403, the pressing components 402 being provided with a second threading space for conveying the bundling belt so that the bundling belt is arranged around the material to be bundled; the two pressing components 402 are oppositely arranged and form a pressing space, the pressing components 402 are arranged on the mounting frame 401, and the driving component 403 is used to drive at least one pressing component 402 to reciprocate on the mounting frame 401; the moving seat 101 reciprocates between the pressing machine and the pressing assembly 400.

[0088] Specifically, before the material to be bundled in the carrier 102 is bundled, it is first conveyed into the pressing assembly 400 so that the material to be bundled is clamped between the two pressing components 402. In order to meet the conveying of the bundling belt in cooperation with the bundling machine 200, a second threading space is configured on the pressing component 402, so that during the bundling operation, the bundling belt can be conveyed through the second threading space to meet the requirement of winding the bundling belt around the material to be bundled for one turn for bundling and packaging.

[0089] Among them, a plurality of pressing blocks 404 arranged side by side are formed on the pressing component 402, and a mounting groove is formed between adjacent two pressing blocks 404, the mounting groove constitutes the second threading space, and a first auxiliary belt groove 405 is arranged in the mounting groove, the first auxiliary belt groove 405 is used to butt joint with the belt groove on the packaging head 201 to convey the bundling belt.

[0090] Specifically, by configuring a plurality of pressing blocks 404 arranged side by side on the pressing component 402, the pressing blocks 404 provide support to the material to be bundled output by the carrier 102 to maintain the material to be bundled in a compressed state. In addition, the first auxiliary belt groove 405 can be arranged between adjacent two pressing blocks 404 to meet the conveying of the bundling belt from the top and bottom of the material to be bundled.

[0091] Meanwhile, the plurality of pressing blocks 404 arranged on the pressing component 402 can accommodate the material to be bundled output by the carrier 102 on one hand, and facilitate the output of the material to be bundled from the carrier 102 on the other hand. Specifically, when conveying the material to be bundled, the plate body constituting the carrier 102 can be inserted between two adjacent pressing blocks 404. Then, the driving component 403 drives the pressing component 402 to move, so that the pressing blocks 404 abut against the material to be bundled in the carrier 102, and the material to be bundled in the carrier 102 is further compressed by the plurality of pressing blocks 404. In this way, the carrier can be easily separated from the two pressing components 402, and the material to be bundled is output from the carrier 102 and left between the two pressing components 402. Moreover, during bundling, the two pressing components 402 can be driven by the driving component 403 to separate from each other according to the strength of the bundling tape and the swelling degree requirement of the material to be bundled later, so that the material to be bundled can be controllably pre-swelled as needed, thereby further improving the packaging quality and further improving the bundling and packaging versatility of the compressible material with different swelling requirements.

[0092] In addition, in order to better meet the conveying requirement of the bundling tape, the mounting frame 401 is further provided with a slidable auxiliary support 406, and the auxiliary support 406 is provided with a second auxiliary tape groove 407 for connecting the two first auxiliary tape grooves 405 arranged opposite to each other on the two pressing components 402 to convey the bundling tape.

[0093] During the bundling process, the bundling tape output from the bundling machine 200 passes through one of the first auxiliary tape grooves 405, the second auxiliary tape groove 407, and the other first auxiliary tape groove 405 in sequence to be conveyed back to the bundling machine 200 to complete the conveying of the bundling tape.

[0094] In order to keep the protective layer on the material to be bundled in the covering and pressing assembly 400 from moving before bundling, the pressing assembly 400 is configured with a retaining clamp at the corresponding position to position and clamp the protective layer as needed, and the specific configuration manner is not limited and described herein.

[0095] Further, after the protective layer and the material to be bundled are bundled together, the two pressing components 402 are driven to separate from each other by the driving component 403, and the bundled material can be pushed out of the extrusion assembly 400. In order to fully protect the bundled material, the automatic packaging system can also be provided with auxiliary equipment for wrapping the protective layer outside the bundled material, wherein the performance entity of the auxiliary equipment is different according to the way of covering the protective layer on the bundled material. For example, the auxiliary equipment can be a cold stretching machine, which wraps the bundled material outside with a protective layer by stretching the film; or the auxiliary equipment can be a bagging machine, which wraps a protective bag outside the bundled material to form a protective layer; or the auxiliary equipment can be a film winding machine, which winds a protective film outside the bundled material to form a protective layer. The specific performance entity of the auxiliary equipment is not limited and described here.

[0096] In another embodiment, in order to realize that the surface of the material to be bundled is fully covered with a protective layer before the bundling operation is performed, and then the whole bundled material is wrapped again after the bundling operation is completed.

[0097] As shown in Figure 7 The film coating device 300 includes an end film coating assembly 2 and a side film coating assembly 3 arranged on one side of the bundling machine 200, the end film coating assembly 2 is used to deliver a protective layer to cover the bottom and top surfaces of the material to be bundled, and the side film coating assembly 3 is used to deliver a protective layer to cover the side surface of the material to be bundled.

[0098] Specifically, for the material to be bundled delivered by the carrier 102, it needs to enter the extrusion assembly 400 for temporary storage to complete the packaging operation after being output from the carrier 102. Before the material to be bundled enters the extrusion assembly 400, the outside of the material to be bundled needs to be wrapped with a protective layer.

[0099] Therefore, the film coating device 300 covers the bottom and top surfaces of the material to be bundled with the end film coating assembly 2, and covers the side surface of the material to be bundled with the side film coating assembly 3. In this way, before the bundling operation is performed by the bundling machine 200, the material to be bundled can be completely wrapped with a protective layer.

[0100] There are many specific ways and structural forms of the end film coating assembly 2 and the side film coating assembly 3 to cover the protective layer, which will be described below in conjunction with the drawings.

[0101] Structure form one, as shown in Figures 7-9As shown, the end film coating assembly 2 comprises a second support frame 21 and a second unwinding mechanism 22 arranged on the second support frame 21 and used for unwinding the coiled material with the protective layer, the second unwinding mechanism 22 is arranged above the carrier 102, and the second support frame 21 forms a film coating space for the carrier 102 to pass through.

[0102] Specifically, the second support frame 21 in the end film coating assembly 2 is arranged vertically and located at the front side of the bundling machine 200, and the second unwinding mechanism 22 shields the protective layer unwound from the coiled material before the extrusion assembly 400, so that after the to-be-bundled material output from the carrier 102 is input into the extrusion assembly 400, the to-be-bundled material will drive the protective layer to enter between the two pressure components 402 in the extrusion assembly 400, so that the top and bottom surfaces of the to-be-bundled material are covered with the protective layer.

[0103] At the same time, in order to facilitate the protective layer output by the end film coating assembly 2 to shield and protect the front and back surfaces of the to-be-bundled material, the extrusion assembly 400 is additionally provided with a turnover frame 408 on the mounting frame 401.

[0104] Specifically, the mounting frame 401 is additionally provided with a turnover frame 408 which is arranged at the lower pressure component 402 and used for turning the protective layer upward to cover the to-be-bundled material. In actual operation, the end film coating assembly 2 outputs a protective layer long enough, so that after the to-be-bundled material is output from the carrier 102 and enters the extrusion assembly 400, the top surface, front surface and bottom surface of the to-be-bundled material are covered with the protective layer, the coiled material on the end film coating assembly 2 is cut, so that the part of the protective layer hanging down from the top of the to-be-bundled material covers the back surface of the to-be-bundled material, and at the same time, the turnover frame 408 is turned over to turn over the protective layer hanging down from the bottom of the to-be-bundled material and overlap with the part of the protective layer hanging down from the top. In this way, the protective layer output by the second unwinding mechanism 22 covers the upper and lower front and rear surfaces of the to-be-bundled material.

[0105] For the side film coating assembly 3, a side film coating assembly 3 is arranged on both sides of the end film coating assembly 2 respectively, so as to cover the left and right side surfaces of the to-be-bundled material with the protective layer through the corresponding side film coating assembly 3.

[0106] The side coating assembly 3 includes a third support frame 31, a third unwinding mechanism 32, and a second clamping mechanism 33. The third unwinding mechanism 32 is mounted on the third support frame 31 and is used to unwind the roll material with the protective layer wound on it. The second clamping mechanism 33 is arranged on the outside of the third support frame 31. The second clamping mechanism 33 includes a mounting bracket 331, a sliding seat 332, a second sliding frame 333, and a second gripper 334. The sliding seat 332 is slidably mounted on the mounting bracket 331 along the moving direction of the moving seat 101. The second sliding frame 333 is arranged laterally and slidably mounted on the sliding seat 332 perpendicular to the moving direction of the moving seat 101. The second gripper 334 is used to clamp the protective layer output by the third unwinding mechanism 32 and transport the protective layer to the side of the material to be bundled.

[0107] Specifically, the third support frame 31 is distributed on the corresponding side of the second support frame 21 to support the installation of the third unwinding mechanism 32. The protective layer output by the third unwinding mechanism 32 is held by the second clamping mechanism 33 and conveyed to the corresponding side of the material to be bundled for coverage. The sliding seat 332 can slide back and forth between the protective component 1 and the third support frame 31. After the sliding seat 332 moves to the side of the protective component 1, the second sliding frame 333 drives the second gripper 334 to approach the corresponding side of the material to be bundled, so that the protective layer covers the left and right sides of the material to be bundled.

[0108] Structural form two, such as Figures 10-12 As shown, the end-coating assembly 2 includes a fourth support frame 23, a fourth unwinding mechanism 24, and a third clamping mechanism 25. The fourth unwinding mechanism 24 is arranged above the carrier frame 102, and the fourth support frame 23 forms a coating space for the carrier frame 102 to pass through. The third clamping mechanism 25 includes a third sliding frame (unmarked) and a third gripper (unmarked). The third sliding frame is slidably mounted on the fourth support frame 23, and the third gripper is used to clamp the protective layer output by the third unwinding mechanism 32 to cover the top and bottom surfaces of the material to be bundled. The fourth support frame 23 is located on one side of the bundling machine 200.

[0109] Specifically, such as Figure 10 The end-coating assembly 2 shown has a similar structure to the protective assembly 1 in the above embodiment, and will not be described in detail here. After the end-coating assembly 2 unwinds the roll material through the fourth unwinding mechanism 24, the cut protective layer is clamped by the third clamping mechanism 25. The third clamping mechanism 25 pre-positions the protective layer at the pressure applying components 402 arranged vertically in the extrusion assembly 400. In this way, the vertically arranged protective layer is pre-placed on the extrusion assembly 400 so that after the material to be bundled is output from the transport frame 102, the top and bottom surfaces of the material to be bundled are covered by the vertically arranged protective layer.

[0110] Correspondingly, in order to facilitate the placement of the upper and lower protective layers on the extrusion assembly 400 in advance, the mounting frame 401 is further provided with an upper holding clamp jaw 409 and a lower holding clamp jaw 410, the upper holding clamp jaw 409 is used to clamp the protective layer to cover the top surface of the material to be bundled, and the lower holding clamp jaw 410 is used to clamp the protective layer to cover the bottom surface of the material to be bundled.

[0111] Specifically, the third clamping mechanism 25 clamps the protective layer to move to the upper holding clamp jaw 409 and the lower holding clamp jaw 410 in turn, so that the upper holding clamp jaw 409 and the lower holding clamp jaw 410 clamp the protective layer respectively. In this way, after the material to be bundled in the carrier 102 is transported to the extrusion assembly 400, the top surface and the bottom surface of the material to be bundled are covered by the protective layer correspondingly.

[0112] Among them, for the specific structure form of the second unwinding mechanism 22, the third unwinding mechanism 32 and the fourth unwinding mechanism 24, please refer to the description of the first unwinding mechanism 13, which will not be repeated here.

[0113] At the same time, the side film covering assembly 3 is arranged on one side of the end film covering assembly 2, the side film covering assembly 3 includes a film feeding mechanism 34 and a wrapping mechanism 35, the film feeding mechanism 34 includes a film feeding support 341 and a first film feeding clamp jaw 342, the first film feeding clamp jaw 342 is slidably arranged on the film feeding support 341; the wrapping mechanism 35 includes a sliding frame 351, a first moving frame 352, a second moving frame 353 and a rotating frame 354, the first moving frame 352 is arranged transversely and slidably on the sliding frame 351, the second moving frame 353 is arranged transversely and slidably on the first moving frame 352, the rotating frame 354 is arranged rotatably on both sides of the first moving frame 352, the second moving frame 353 is provided with a second film feeding clamp jaw 356, and the rotating frame 354 is provided with a third film feeding clamp jaw 357; the sliding frame 351 can reciprocate between the film feeding support 341 and the extrusion assembly 400.

[0114] Specifically, the side film covering assembly 3 completes the unwinding of the coiled material through the film feeding mechanism 34 to output the protective layer, and the wrapping mechanism 35 is used to fold and shape the protective layer unwound by the film feeding mechanism 34, so that the protective layer clamped by the wrapping mechanism 35 forms a U-shaped structure, and then the protective layer is sleeved on the outer periphery of the material to be bundled through the wrapping mechanism 35, so that the protective layer wraps the outer periphery of the material to be bundled. Among them, the sliding directions of the first moving frame 352 and the second moving frame 353 are perpendicular to the sliding direction of the sliding frame 351.

[0115] The specific operation process is as follows: the coil material vertically placed on the film feeding support 341 is clamped by the first film feeding clamp jaw 342 to hold the end portion and move outward, so that the coil material unwinds to a set length of the protective layer. The first moving frame 352 drives the rotating frame 354 to move, and the third film feeding clamp jaw 357 approaches the protective layer pulled out by the first film feeding clamp jaw 342, and the third film feeding clamp jaw 357 away from the coil material 2000 side first clamps the protective layer; then, the second moving frame 353 drives the second film feeding clamp jaw 356 to move, and the second film feeding clamp jaw 356 approaches the protective layer, and the protective film is located in the second film feeding clamp jaw 356, and the second moving frame 353 drives the second film feeding clamp jaw 356 to move reversely, and the protective layer is pulled into a U shape; finally, the first film feeding clamp jaw 342 moves to the outside of the third film feeding clamp jaw 357 on the coil material side and resets and clamps the protective layer, and the third film feeding clamp jaw 357 on the coil material side also clamps the protective layer, and the cutter arranged on the film feeding support 341 cuts the protective layer between the first film feeding clamp jaw 342 and the third film feeding clamp jaw 357.

[0116] In this way, the protective layer in a U shape is formed on the wrapping mechanism 35. At this time, the sliding frame 351 drives the protective layer in a U shape to move from the film feeding mechanism 34 to the direction of the extrusion assembly 400, and after moving to the position, the first moving frame 352 is extended to make the protective layer in a U shape surround the front and left and right sides of the material to be bound, and then the rotating frame 354 is rotated to make the two end portions of the protective layer turn over and cover the back of the material to be bound. In this way, the operation of covering the protective layer on the circumferential side of the material to be bound can be completed.

[0117] Further, in order to facilitate the adjustment of the height position of the protective layer, the lifting frame 358 is arranged on the sliding frame 351, and the first moving frame 352 is slidably arranged on the lifting frame 358.

[0118] In addition, it should be noted that the sliding frame, the moving frame, the lifting frame and the rotating frame involved in the present application are driven by the corresponding driving units to realize the corresponding operation, and the driving mode of the driving unit to realize the sliding or rotation of the driven part can refer to the driving mode in the conventional technology, which is not limited and described here.

[0119] The application also provides a packaging line, which comprises a baling press and the automatic packaging system in the above embodiments. The baling press is used for compressing the compressible material to form the material to be bound, and the carrying frame in the automatic packaging system is used for taking out the material to be bound compressed in the baling press.
