[0065] The present application provides a film winding device. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments.

[0066] Please refer to Figures 1 to 2The embodiment of the present application provides a film winding equipment 1, which comprises a film unwinding assembly 10, a rotating assembly 30 and a material belt arrangement assembly 20. The film unwinding assembly 10 is used for unwinding a film material roll. The rotating assembly 30 is used for carrying and driving a product 3 to rotate around a rotating axis, so that the material belt can be wound on the product. The material belt arrangement assembly 20 is arranged between the film unwinding assembly 10 and the rotating assembly 30 along the conveying direction of the material belt, so as to adjust the position of the material belt conveyed by the film unwinding assembly 10 to the rotating assembly 30 in a first direction, and further adjust the winding position of the material belt on the product 3, wherein the first direction is parallel to the extension direction of the rotating axis.

[0067] Compared with the prior art, in the film winding equipment 1, the material belt arrangement assembly 20 is additionally arranged between the film unwinding assembly 10 and the rotating assembly 30, so as to adjust the feeding position of the material belt in the first direction, so that the winding position of the material belt on the product can be flexibly and accurately controlled, the film winding equipment 1 can match products of more sizes and specifications, so that the film winding quality of the product can be improved, the compatibility of the film winding equipment 1 with the product 3 and / or the material belt can be improved, and the versatility of the film winding equipment 1 is provided.

[0068] In some embodiments, referring to Figure 3 The base 90 is used for carrying the whole film winding equipment 1. The base 90 has a hollow inner cavity, and the hollow inner cavity is used for arranging part of components of the film winding equipment 1. Specifically, please refer to the following. Illustratively, the base 90 is a cuboid as a whole. The base 90 has a length direction X, a width direction Y and a height direction Z. The first direction is consistent with the height direction Z of the base 90.

[0069] Referring to Figure 3 The film unwinding assembly 10 comprises a positioning column 11 vertically installed on the base 90 and a tray 12 installed on the positioning column 11. The positioning column 11 is columnar, and the axis direction of the positioning column 11 is parallel to the first direction. The tray 12 is disc-shaped as a whole, and the tray 12 is vertically installed on the positioning column 11 and used for containing the film material roll. Specifically, in use, the film material roll 2 is arranged around the periphery of the positioning column 11 and placed on the tray 12, and the film material roll 2 is rotatably arranged relative to the tray 12 or the positioning column 11, so as to rotate and unwind the film material roll 2.

[0070] Wherein the tray 12 and / or the positioning column 11 is movably arranged along the first direction. In this way, by adjusting the position of the tray 12 and / or the positioning column 11 along the first direction, the position of the film roll 2 along the first direction can be adjusted, so as to control the winding position of the material belt on the product 3.

[0071] Preferably, the side of the tray 12 is fixedly installed on the positioning column 11 by means of bolts. By adjusting the position of the tray 12 relative to the positioning column 11, the position of the film roll 2 along the first direction can be adjusted, so as to adjust the winding position of the material belt on the product 3.

[0072] In some other embodiments, the tray 12 is fixedly installed on the positioning column 11, and the positioning column 11 is movably arranged along the first direction. At this time, by adjusting the position of the positioning column 11 along the first direction, the position of the tray 12 and the film roll 2 carried on the tray 12 along the first direction can be adjusted, so as to achieve the purpose of adjusting the position of the film roll 2 along the first direction.

[0073] In order to achieve the purpose of unwinding the film roll 2, the film roll 2 is rotatably arranged. In the present embodiment, the film roll 2 is rotatably arranged relative to the tray 12, and the tray 12 is fixedly installed on the positioning column 11. That is, the tray 12 is fixed relative to the positioning column 11, and the film roll 2 rotates relative to the tray 12 under the drive of the rotating assembly 30 to release the material belt.

[0074] In some other embodiments, the tray 12 is circumferentially rotatable relative to the positioning column 11, the film roll 2 is circumferentially fixedly arranged on the tray 12, and the tray 12 and the film roll 2 rotate relative to the positioning column 11 under the drive of the rotating assembly 30 to unwind and release the material belt. At this time, the positioning of the film roll 2 is better, and the edge of the film roll 2 is prevented from being damaged in the rotating process.

[0075] The above illustrates an embodiment in which the unwinding assembly 10 is configured to be passive unwinding. Passive unwinding means that the film roll 2 or the tray 12 is rotated synchronously under the pulling of the tape (the tape is driven by the rotating assembly 30) to release the tape. That is, the unwinding assembly 10 is not configured with a driving member or a driving mechanism to drive the film roll 2 and / or the tray 12 to rotate. However, it should be noted that the application does not limit the unwinding mode of the unwinding assembly 10. For example, the unwinding assembly 10 can also be configured to be active unwinding, that is, the film roll 2 or the tray 12 is actively driven to continuously release the tape. As the name implies, the unwinding assembly 10 is provided with a driving member or a driving mechanism to drive the film roll 2 to rotate. At this time, in order to realize the synchronization of unwinding and winding actions, a tensioning mechanism can also be provided on the conveying path of the tape.

[0076] In some embodiments, the unwinding assembly 10 is multiple. At this time, the tape arrangement assembly 20 can define the position of the tape of each unwinding assembly 10 in the first direction, and combine multiple tapes into a composite tape or a spliced tape, and then provide the composite tape or the spliced tape to the rotating assembly 30 at a target position. In this way, the film winding device 1 of the application can simultaneously wind two or even more types of tapes, thereby improving the film winding efficiency of the film winding device 1. In addition, the tape arrangement assembly 20 can adjust the position of the tape wound on the product 3, improve the flatness of the tape, and thus improve the quality of the film winding.

[0077] As shown in Figure 3 The tape arrangement assembly 20 includes a plurality of tape guides 22 and a tape combining member 21. The plurality of tape guides 22 correspond to the plurality of unwinding assemblies 10 respectively, and each tape guide 22 is located between the corresponding unwinding assembly 10 and the tape combining member 21 along the conveying direction of the tape, so as to adjust the position of the tape unwound by the corresponding unwinding assembly 10 in the first direction and provide the tape to the tape combining member 21.

[0078] The tape combining member 21 is located downstream of the plurality of tape guides 22, and the tape combining member 21 simultaneously receives the tapes unwound by the plurality of unwinding assemblies 10 and combines the plurality of tapes to form a composite tape or a spliced tape, and then provides the composite tape or the spliced tape to the rotating assembly 30 at a target position. That is, the plurality of tapes unwound by the plurality of unwinding assemblies 10 are combined into a composite tape or a spliced tape at the tape combining member 21, and then the composite tape or the spliced tape enters the rotating assembly 30 at a target position.

[0079] The "spliced material belt" refers to that a plurality of the material belts are spliced in a width direction of the material belt. At this time, the width of the material belt entering the rotating assembly 30 can be adjusted according to the size of the highlight surface of the product, thereby improving the film winding efficiency. For illustration, please refer to Figure 3 In the embodiment, the material belts released from the two film material rolls 2 are spliced into a spliced material belt at the material belt splicing member 21.

[0080] The "composite material belt" refers to that a plurality of the material belts are stacked in a thickness direction of the material belt splicing member 21 to be stacked or laminated into a multi-layer stacked structure. At this time, the thickness of the material belt can be adjusted to meet the requirement of protecting the highlight surface of the product 3.

[0081] It can be understood that in specific implementation, the plurality of the material belts can be selectively spliced into a spliced material belt or a composite material belt by adjusting the positions of the plurality of the material belts in the first direction.

[0082] In some embodiments, the number of the material belt guides 22 is the same as the number of the unwinding assemblies 10. That is, each of the material belt guides 22 corresponds to one of the unwinding assemblies 10. For illustration, please further refer to Figure 3 The number of the unwinding assemblies 10 is two, and the number of the material belt guides 22 is two. The two material belt guides 22 are respectively located at the downstream side of the corresponding unwinding assemblies 10, and both of the two material belt guides 22 are located at the upstream side of the material belt splicing member 21. However, it should be pointed out that the specific implementation of the material belt arrangement assembly 20 of the present application is not limited to this. For example, in some other embodiments, the number of the material belt guides 22 is more than the number of the unwinding assemblies 10 to improve the guiding effect of the material belt.

[0083] For illustration, the material belt guide 22 and the material belt splicing member 21 both include a guide column 210 and a limiting member 220. The guide column 210 is in a cylindrical shape, and the axis of the guide column 210 is parallel to the rotating axis, that is, the axial direction of the guide column 210 is parallel to the first direction. The limiting member 220 is arranged on the guide column 210 to limit the material belt abutting against the guide column 210 in the axial direction of the guide column 210.

[0084] In some embodiments, the limiting member 220 includes two limiting blocks. The two limiting blocks are spaced apart along the axial direction of the guide post 210 to form a limiting channel through which the material strip can pass. Further, at least one of the two limiting blocks is movable relative to the guide post 210 along the axial direction of the guide post 210. In specific implementations, the spacing between the two limiting blocks along the axial direction of the guide post 210 can be adjusted to flexibly adjust the width and position of the limiting channel.

[0085] In practice, the limiting block is generally annular with an opening. The limiting block is fixed in place by means of bolts.

[0086] like Figure 4 As shown, in some embodiments, the rotating assembly 30 includes a rotating platform 31 and a rotating drive 32. The rotating platform 31 is used to support the product 3, and the rotating drive 32 is driven to the rotating platform 31 to drive the rotating platform 31 to rotate around the central axis, thereby driving the product 3 to rotate synchronously through the rotating platform 31.

[0087] In specific implementation, the rotating platform 31 is used to directly or indirectly support the product 3. In this embodiment, the rotating platform 31 is used to directly support the product 3. Further, a positioning structure is provided on the upper surface of the rotating platform 31, and the product 3 is mounted on the rotating platform 31 through the positioning structure to prevent the product 3 from rotating relative to the rotating platform 31.

[0088] Schematic illustration: The positioning structure is a protruding insertion protrusion on the upper surface of the rotary table 31, and the bottom of the product 3 has an insertion groove that engages with the protrusion. In other embodiments, the rotary table 31 can carry the product 3 using a carrier tray or pallet. With this design, only the corresponding carrier tray or pallet needs to be replaced for different products 3, thus the rotary table 31 meets the requirements for carrying multiple products 3, which is beneficial for achieving the versatility of the wrapping equipment 1. Therefore, this application does not substantially limit the specific implementation of the rotary table 31.

[0089] Further, the rotating assembly 30 further comprises a mounting bracket 33 and a transmission member 34. The mounting bracket 33 comprises a lower mounting plate 331, an upper placing plate 332 and a connecting side plate 333 connected between the lower mounting plate 331 and the upper placing plate 332. The lower mounting plate 331 is mounted on the base 90, the rotating drive member 32 is received in the hollow inner cavity of the base 90, and the rotating shaft of the rotating drive member 32 is transmissionally penetrated through the top plate of the base 90 and the lower mounting plate 331. The rotating table 31 is mounted on the upper placing plate 332, and the rotating shaft of the rotating table 31 is rotatably penetrated through the upper placing plate 332. The transmission member 34 is arranged between the lower mounting plate 331 and the upper placing plate 332, and is transmissionally connected with the rotating shaft of the rotating drive member 32 and the rotating shaft of the rotating table 31. In a specific implementation, the rotating drive member 32 is a motor, and the transmission member 34 is a shaft coupling.

[0090] Further, in order to detect and control the number of winding turns, a counting assembly 35 is arranged on the rotating assembly 30. The counting assembly 35 has a counting member 351 and a detecting member 352. The counting member 351 is provided with a to-be-detected structure 3511 which can be detected by the detecting member 352, and the detecting member 352 is used for detecting the to-be-detected structure 3511. Moreover, only one of the counting member 351 and the detecting member 352 is driven by the rotating drive member 32 and rotates synchronously with the rotating table 31. In this way, the detecting member 352 determines the number of rotating turns of the rotating table 31 according to the number of times of detecting the to-be-detected structure 3511, and further determines the number of winding turns of the product 3. In a specific implementation, when the number of winding turns of the product 3 reaches a predetermined number, the rotating table 31 is controlled to stop rotating by the rotating drive member 32, and the winding is stopped.

[0091] Please refer to FIG. 4, and specifically to the present example, the counting member 351 rotates synchronously with the rotating table 31. The detecting member 352 is arranged on the mounting bracket 33. Specifically, the counting member 351 is torsionally mounted on the transmission member 34.

[0092] As Figure 5As shown, in order to fix the product 3 on the rotating table 31, the film winding device 1 further comprises a fixing assembly 40. The fixing assembly 40 comprises a driven pressing block 41 and a pressing block driving member 42. The driven pressing block 41 is arranged opposite to the rotating table 31 along the first direction, and can rotate around the rotating axis and can approach or move away from the rotating table 31 along the extension direction of the rotating axis. The pressing block driving member 42 is drivingly connected with the driven pressing block 41 to drive the driven pressing block 41 to approach or move away from the rotating table 31 along the first direction, so as to make the driven pressing block 41 and the rotating table 31 cooperatively clamp or release the product 3. In the embodiment, the product 3 has a bowl-shaped structure, the outer bottom surface of the product 3 is mounted on the rotating table 31, and the driven pressing block 41 extends into the product 3 and abuts against the inner bottom surface of the product 3.

[0093] In specific implementation, the pressing block driving member 42 is a cylindrical air cylinder.

[0094] Further, the fixing assembly 40 is fixedly mounted on the top of the base 90 by a support member 43, and the driven pressing block 41 is mounted on the top of the support member 43. In specific implementation, the support member 43 is a support sheet metal.

[0095] In actual work, the product 3 to be wound with film is placed on the rotating table 31 of the rotating assembly 30, the driven pressing block 41 is driven by the pressing block driving member 42 to move towards the direction of approaching the rotating table 31, so that the driven pressing block 41 fixes the product 3 on the rotating table 31; after the film winding is completed, the driven pressing block 41 is driven by the pressing block driving member 42 to move away from the rotating table 31 along the first direction, and then the product 3 with the wound film can be taken out.

[0096] In some embodiments, the film winding device 1 has a first station and a second station. The unwinding assembly 10 is arranged on the first station, and the rotating assembly 30 is arranged on the second station.

[0097] Based on the above embodiments, in order to realize automatic film wrapping, the film wrapping device 1 further comprises a material clamping assembly 50, a moving assembly 60, a material pressing assembly 70 and a material cutting assembly 80. The material clamping assembly 50 is arranged between the material band arranging assembly 20 and the rotating assembly 30 along the conveying direction, for controlled clamping or releasing of the material band. The moving assembly 60 is drivingly connected to the material clamping assembly 50, for driving the material clamping assembly 50 to move between a first station and a second station, so as to bring the material band to the rotating assembly 30 by the material clamping assembly 50. The material pressing assembly 70 is arranged at one side of the rotating assembly 30, and located at a side of the material band away from the rotating assembly 30, for pressing the material band on the product 3. The material cutting assembly 80 is arranged at one side of the rotating assembly 30, and located at a side of the material band away from the rotating assembly 30, for cutting the material band after the product 3 is wrapped with film.

[0098] Further, referring to Figure 7 and Figure 8 , the base 90 is provided with a mounting rack 91 for carrying the material cutting assembly 80 and the material pressing assembly 70. By arranging the mounting rack 91, the positions of the material cutting assembly 80 and the material pressing assembly 70 in the first direction Z can be adjusted, so as to ensure that the material cutting assembly 80 and the material pressing assembly 70 can contact the material band. In the embodiment, the mounting rack 91 is arranged at one side of the rotating assembly 30 along the length direction X of the base 90, and the mounting rack 91 has a double-layer structure, which comprises a lower fixed plate 911, an upper carrying plate 912 and a plurality of support columns 913 connected between the lower fixed plate 911 and the upper carrying plate 912. The bottom of the lower fixed plate 911 is fixedly mounted on the base 90, and the material cutting assembly 80 and the material pressing assembly 70 are placed on the top of the upper carrying plate 912. In some embodiments, the mounting rack 91 is detachably mounted on the base 90, and the height of the mounting rack 91 in the first direction Z is adjusted, so as to adjust the positions of the material cutting assembly 80 and the material pressing assembly 70 in the first direction Z.

[0099] Further in combination with the base 90 embodiment, the rotating assembly 30, the clamping assembly 50, the moving assembly 60, the pressing assembly 70 and the cutting assembly 80 are all arranged on the top plate of the base 90. And, the unwinding assembly 10 and the mounting frame 91 are located at one side of the top plate along the length direction X, the rotating assembly 30 and the tape arranging assembly 20 are located at the other side of the top plate along the length direction X, and the clamping assembly 50 and the moving assembly 60 are located in the area of the top plate along the length direction X. In this way, the compactness and integration of the film winding device can be improved. The above describes the relative arrangement of the rotating assembly 30, the clamping assembly 50, the moving assembly 60, the pressing assembly 70 and the cutting assembly 80 on the base 90. The specific embodiments of the clamping assembly 50, the moving assembly 60, the pressing assembly 70 and the cutting assembly 80 will be described in detail below.

[0100] Please refer to Figure 6 In some embodiments, the moving assembly 60 comprises a moving slide rail 61 and a moving drive 62. The moving slide rail 61 is arranged on the top plate of the base 90 (see the reference number Figure 1 and Figure 2 ) and is located between the rotating assembly 30 and the mounting frame 91 along the length direction X of the base 90, and the moving slide rail 61 extends along the width direction Y. In this embodiment, the moving drive 62 is fixed to the base 90 by a fixing member 621, and the driving end of the moving drive 62 is connected with the clamping assembly 50.

[0101] Further, the moving drive 62 is arranged on the top plate of the base 90. The moving drive 62 is arranged adjacent to one side of the moving slide rail 61 towards the mounting frame 91, and the moving drive 62 is arranged on the side of the moving drive 62 facing the tape arranging assembly 20 along the width direction Y. Further, the moving drive 62 is arranged between the guide columns 210 of the tape arranging assembly 20. In this way, the integration of the film winding device 1 can be improved, and the volume of the film winding device 1 can be reduced.

[0102] In specific implementation, the moving drive 62 is a cylindrical air cylinder, and the axis of the cylindrical air cylinder is parallel to the moving slide rail 61.

[0103] In some other embodiments, the moving assembly 60 further comprises a moving slide block, the moving slide block is slidingly connected to the moving slide rail 61, and the clamping assembly 50 is fixedly arranged on the moving slide block.

[0104] As Figure 6As shown, the material clamping assembly 50 is slidably arranged above the moving slide rail 61, and the height of the material clamping assembly 50 from the top plate of the base 90 is substantially the same as the height of the rotating table 31 from the base 90.

[0105] Further, the material clamping assembly 50 comprises a clamp 51 and a material clamping driving member 52. The clamp 51 has a first clamping member 511 and a second clamping member 512 which can be moved towards or away from each other. The material clamping driving member 52 is drivingly connected with the clamp 51 to drive the first clamping member 511 and the second clamping member 512 to move towards or away from each other, so as to clamp or release the material belt.

[0106] In specific embodiments, the clamp 51 further comprises a first slide rail 513 arranged on the housing of the material clamping driving member 52, and the first clamping member 511 and the second clamping member 512 are respectively slidably arranged at opposite ends of the first slide rail 513. The driving end of the material clamping driving member 52 is drivingly connected with the first clamping member 511 and / or the second clamping member 512 to drive the first clamping member 511 and the second clamping member 512 to move towards or away from each other along the first slide rail 513, so as to clamp or release the material belt. In specific embodiments, the material clamping driving member 52 is a rectangular cylinder.

[0107] Further, the surfaces of the first clamping member 511 and the second clamping member 512 which move towards each other are clamping surfaces for clamping the material belt. The two clamping surfaces are parallel planes to prevent the material belt from being crushed. In specific embodiments, a buffer layer or an elastic layer is arranged on the clamping surfaces of the first clamping member 511 and the second clamping member 512 to prevent the material belt from being damaged.

[0108] Further reference can be made to Figure 7 and Figure 8In some embodiments, the material pressing assembly 70 comprises a pressing roller assembly 71 and a pressing roller driving assembly 72. The pressing roller driving assembly 72 is drivingly connected to the pressing roller assembly 71 to drive the pressing roller assembly 71 to move towards the rotating assembly 30 along a second direction which is perpendicular to the first direction. The pressing roller assembly 71 comprises a pressing roller 711 which is rotatably arranged to press the material tape against the product 3, and an elastic assembly 712 which is connected between the pressing roller 711 and the pressing roller driving assembly 72 and is elastically deformable along the second direction. In the embodiments of the present application, the pressing roller 711 extends out of the mounting frame 91 and is suspended above the moving guide rail 61, so that the space size of the film winding device 1 can be fully utilized and the compactness of the film winding device can be improved.

[0109] In the embodiments of the present application, the second direction is parallel to the length direction X of the base 90. At this time, the material pressing assembly 70 is arranged on one side of the rotating assembly 30 along the length direction X and is located on the side of the material tape which is away from the rotating assembly 30 along the length direction X.

[0110] In actual work process, since the elastic assembly 712 is elastically deformable along the second direction (i.e. the length direction X), the pressing roller 711 will not press the product 3 when pressing the material tape against the surface of the product 3 (see Figure 1 ), and will not cause the material tape to fall down due to insufficient pressure.

[0111] Specifically, the pressing roller 711 is a driven pressing roller. That is, the pressing roller 711 is rotatable under the driving of the material tape, so as to avoid relative friction between the pressing roller 711 and the material tape, and further to prevent the pressing roller 711 from damaging or scratching the material tape. Further, the rotation axis of the pressing roller 711 is arranged in parallel to the rotation axis of the rotating table 31 (see Figure 1 ). The pressing roller 711 has a cylindrical structure or a conical table structure.

[0112] In one embodiment, as Figure 7As shown, the elastic assembly 712 includes a connecting plate 7121, a slide rod, an elastic piece 7122, and a connecting block 7123. The slide rod extends along the second direction and is composed of a fixed segment and a slide segment. The slide segment is in slide fit with the connecting plate 7121, and the fixed segment is fixedly connected with the connecting block 7123. The elastic piece 7122 is sleeved outside the slide rod, and two ends of the elastic piece 7122 abut against the connecting plate 7121 and the connecting block 7123 respectively. In the embodiment, the slide rod is a cylindrical rod structure, and the elastic piece 7122 is a spring. When the spring is sleeved on the slide rod, the surface on the radially inner side of the spring is in contact with the outer surface of the slide rod.

[0113] Compared with the embodiment in which the elastic assembly 712 only includes the elastic piece 7122, the elastic assembly 712 in the embodiment further includes the connecting plate 7121, the slide rod, and the connecting block 7123, so as to guide the deformation of the elastic piece 7122. As a result, the elastic piece 7122 can only deform in the second direction (i.e., the axial direction of the slide rod), so as to avoid damage to the material belt or the product 3 caused by the inclination of the compression roller 711 and abnormal film winding.

[0114] In some embodiments, the compression roller driving assembly 72 includes a compression roller driving piece 721 and a slide rail mechanism 722. The slide rail mechanism 722 includes a second slide rail 7221 in slide fit and a second slide block 7222 fixedly connected with the connecting block 7123. The second slide rail 7221 is arranged on the upper layer bearing plate 912 of the mounting frame 91, and the compression roller driving piece 721 is arranged adjacent to one side of the second slide rail 7221 and is fixed on the upper layer bearing plate 912 of the mounting frame 91 through a fixing piece 7211. The driving end of the compression roller driving piece 721 is connected to the connecting block 7123 through a connecting piece 7212.

[0115] In a specific implementation, the compression roller driving piece 721 is a cylindrical air cylinder, and the axial direction of the cylindrical air cylinder is parallel to the second direction.

[0116] In some embodiments, the cutting assembly 80 includes a cutter 81 and a cutter driving piece 82. The cutter 81 is located on the upstream side of the rotating assembly 30 and is used to cut the material belt. The cutter driving piece 82 is drivingly connected with the cutter 81 to drive the cutter 81 to move towards or away from the rotating assembly 30. In the embodiment, the cutter 81 extends out of the mounting frame 91 and is suspended above the moving guide rail 61, so that the space size of the film winding equipment 1 can be fully utilized, and the compactness of the film winding equipment can be improved.

[0117] In some embodiments, the cutting assembly 80 is arranged on one side of the rotating assembly 30 along the length direction X and on the side of the material tape away from the rotating assembly 30 along the length direction X.

[0118] Further, the cutting assembly 80 is arranged on the side of the pressing assembly 70 facing the unwinding assembly 10, and the driving of the cutting knife 81 along the second direction towards or away from the rotating assembly 30. At this time, the extension direction of the pressing roller 711 and the movement direction of the cutting knife 81 are the same.

[0119] The specific working process of the film winding device 1 of the present application is as follows:

[0120] Before the film winding device 1 works, the product 3 is installed on the rotating table 31 of the rotating assembly 30, the pressing block driving member 42 drives the driven pressing block 41 to press and fix the product 3 on the rotating table 31, and the film material roll 2 is installed on the tray 12 of the unwinding assembly 10; the material tape of the film material roll 2 is pulled to the clamping assembly 50 after being wound through the material tape arrangement assembly 20, and the clamping assembly 50 clamps the material tape through the clamp 51. Then, the moving assembly 60 drives the clamping assembly 50 to move from the material tape arrangement assembly 20 to the rotating assembly 30 through the moving driving member 62, so as to drive the material tape (here, the material tape can be the material tape released by a single film material roll 2, or can be a composite material tape or a spliced material tape formed by the material tapes of multiple film material rolls 2) to the rotating assembly 30. Then, the pressing assembly 70 controls the pressing roller 711 to extend towards the rotating assembly 30 along the second direction through the pressing roller driving assembly 72, so as to press the material tape on the product 3; at the same time, the clamping assembly 50 controls the clamp 51 to loosen the material tape. Then, the rotating driving member 32 drives the rotating table 31 to rotate, thereby driving the product 3 to rotate to wind the material tape on the product 3 (i.e., film winding); when the counting assembly 35 identifies that the number of turns is the predetermined number of turns, the rotating driving member 32 stops. Subsequently, the clamp 51 of the clamping assembly 50 clamps the composite material tape or the spliced material tape; at the same time, the cutting assembly 80 controls the cutting knife 81 to extend along the second direction, so as to cut the composite material tape or the spliced material tape. Finally, the fixing assembly 40 controls the driven pressing block 41 to move away from the rotating table 31 along the first direction Z, thereby loosening the product 3.

[0121] The present application also provides a film winding method, which comprises the following steps:

[0122] S1: installing the product 3 on the rotating assembly 30 and installing the film material roll 2 on the unwinding assembly 10;

[0123] S2: adjusting the position of the material tape along the first direction by using the material tape arrangement assembly 20, and clamping the material tape on the material clamping assembly 50;

[0124] S3: moving the material clamping assembly 50 to the rotating assembly 30 by using the moving assembly 60 to drive the material clamping assembly 50 to move from the material tape arrangement assembly 20 to the rotating assembly 30, so as to bring the material tape to the rotating assembly 30;

[0125] S4: pressing the material tape on the product 3 by using the material pressing assembly 70, and releasing the material tape by the material clamping assembly 50;

[0126] S5: rotating the product 3 around a rotating axis by using the rotating assembly 30, so as to rotate the product 3 to wrap the film, and the extending direction of the rotating axis is the first direction; and,

[0127] S6: after the film wrapping is completed, stopping the rotating assembly 30 from rotating, clamping the material tape by the material clamping assembly 50, and cutting the material tape by using the material cutting assembly 80.

[0128] Compared with the existing film wrapping method, the film wrapping method of the present application can realize automatic film wrapping, save film wrapping time, and improve film wrapping efficiency. Moreover, the film wrapping method of the present application can adaptively adjust the position of the material tape along the first direction, so as to ensure the accurate film wrapping position of the material tape on the product 3, and improve the film wrapping effect.

[0129] In some embodiments, the step S1 further includes the step of fixing the product 3 on the rotating assembly 30 along the first direction by using the fixing assembly 40. In this way, the stability of the product 3 can be improved, and the film wrapping effect can be improved.

[0130] In the step S1, the number of the film material rolls 2 can be one or more.

[0131] In some embodiments, the number of the film material rolls 2 is multiple, and each of the film material rolls 2 is installed on the tray 12 of the corresponding unwinding assembly 10. Accordingly, in the step S2, the material tapes unwound from the multiple film material rolls 2 are merged into a spliced material tape or a composite material tape by using the material tape arrangement assembly 20, and the position of the spliced material tape or the composite material tape along the first direction is adjusted to a target position by using the material tape arrangement assembly 20. At this time, on the one hand, the width of the material tape entering the rotating assembly 30 can be adaptively adjusted according to the size of the highlight surface of the product, so as to improve the film wrapping efficiency. On the other hand, the material tape entering position of the product 3 can also be adjusted, so as to ensure the accurate wrapping position, improve the flatness of the material tape, and further improve the quality of the film wrapping.

[0132] The film winding method can be implemented by using the film winding device 1 described in the present application. The specific embodiments of the unwinding assembly 10, the material belt arrangement assembly 20, the rotating assembly 30, the fixing assembly 40, the material clamping assembly 50, the moving assembly 60, the material pressing assembly 70, and the material cutting assembly 80 can refer to the foregoing description.

The above description of the embodiments is only used to help understand the method of the present application and its core idea.
