DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0032] Please refer to Figure 1 and Figure 2 , the present application provides a winding film device for PET winding machine, including equipment main body 001 and winding main shaft 002 for winding packing belt installed on equipment main body 001, paper cylinder can be installed on winding main shaft 002 in advance, and the packing belt on production line is wound on the paper cylinder through the rotation of winding main shaft 002, so that the packing belt coil meeting the length is obtained, which is a known technology and will not be described here.

[0033] The difference is that, as Figure 1 , Figure 3、 Figure 4 and Figure 5 As shown in the drawings, the application also comprises a support plate 100, a wrapping film roller 101, a pressure roller one 102, a pressure roller two 103 and a blowing pipe 104;

[0034] The support plate 100 is located above the winding main shaft 002 and is vertically slidingly installed on the front end of the equipment main body 001, and the support plate 100 can be specifically adjusted in the height direction of the equipment main body 001; the wrapping film roller 101 is rotatably installed on the support plate 100, and a film cylinder is installed on the wrapping film roller 101, and the film thereon is used to wrap the plastic packing belt after being rolled and bundled; the pressure roller one 102 is located below the wrapping film roller 101 and is rotatably installed on the support plate 100; the pressure roller two 103 is rotatably installed on the support plate 100, and the pressure roller two 103 is located below one side of the pressure roller one 102, and the side surfaces of the pressure roller two 103 and the pressure roller one 102 are always in close contact; the length of the pressure roller one 102 and the pressure roller two 103 is not less than the overall thickness of the rolled and packed belt on the winding main shaft 002; the blowing pipe 104 is fixedly connected to the support plate 100, one end of the blowing pipe 104 adjacent to the support plate 100 is connected to an external air pump (not shown in the drawings), and a plurality of air outlets are provided on the blowing pipe 104 along the length direction of the pipe, and the air outlets are always directed towards the pressure roller two 103;

[0035] In use: as shown in the drawings, after the packing belt is rolled on the winding main shaft 002, as shown in the drawings, the broken part of the wrapping film on the wrapping film roller 101 can be adhered to the surface of the pressure roller two 103 and located directly below the pressure roller two 103 by blowing of the blowing pipe 104, then as shown in the drawings, the support plate 100 is vertically lowered as a whole until the pressure roller two 103 on the support plate 100 is adhered to the surface of the rolled packing belt, at this time, the broken part of the wrapping film is pressed between the pressure roller two 103 and the rolled packing belt; Figure 2 Figure 5 Figure 6

[0036] It is worth noting that the blowing of the air outlets of the blowing pipe 104 can adjust the position of the film broken part, so that the film broken part can be automatically located between the pressure roller two 103 and the rolled packing belt when the two are adhered, which is convenient for subsequent wrapping and bundling of the film on the rolled packing belt;

[0037] Then, as shown in the drawings, the excess packing belt after wrapping can be cut off by an external belt cutter, since the pressure roller two 103 is in close contact with the rolled packing belt at this time, the rolled packing belt is not bundled at this time, but it will not be loose due to the tight pressing of the pressure roller two 103; Figure 2

[0038] Immediately, as shown in the drawings, and Figure 6 and Figure 7 ​​​​As shown, by the action of the external motor, the winding spindle 002 and the wound baling tape thereon rotate clockwise, the wound baling tape drives the compression roller two 103 to rotate counterclockwise, and the compression roller one 102 and the compression roller two 103 are tightly attached, so that the film on the film winding roller 101 is continuously conveyed between the compression roller one 102 and the compression roller two 103, and is wound onto the wound baling tape with the continuous rotation of the winding spindle 002. After the film is wound on the wound baling tape for a certain number of turns (the number of turns can be set according to actual needs, and is not limited), the film on the wound baling tape is automatically wound to protect the surface of the wound baling tape, that is, the automatic bundling effect is formed. Finally, by controlling the winding spindle 002 to stop rotating through the external motor device, and cutting the film between the compression roller two 103 and the wound baling tape, the wound baling tape after bundling can be disassembled.

[0039] At the same time, as shown in Figure 5 , the cut film head is always located between the compression roller one 102 and the compression roller two 103, and through the limitation of the two rollers on the film, the film head part will not be messy, which is convenient for next time bundling.

[0040] As shown in Figure 2 and Figure 3 , in order to realize the above-mentioned support plate 100, the support plate 100 can be adjusted in the height direction of the equipment body 001. For this purpose, the equipment body 001 is also provided with a cylinder one 200; the equipment body 001 is also provided with a lifting plate 201 through a sliding rail; the support plate 100 is arranged on the lifting plate 201; the output shaft of the cylinder one 200 is downward, and the output shaft is fixedly connected with the lifting plate 201.

[0041] In use: by the action of the cylinder one 200, the output shaft is extended downward, and drives the lifting plate 201 and the support plate 100 thereon to move downward, until the compression roller one 102 on the support plate 100 is attached to the wound baling tape, so as to realize the lifting adjustment of the support plate 100. In other words, by the action of the cylinder one 200, the compression roller two 103 can move downward and be tightly attached to the surface of the wound baling tape, and then the film on the film winding roller 101 can be wound and bundled to the wound baling tape.

[0042] As shown in Figure 4 , Figure 5 and Figure 6 , the compression roller two 103 is provided with a compression roller three 202 away from the compression roller one 102; the compression roller three 202 is rotatably installed on the lifting plate 201; wherein the compression roller two 103 and the compression roller three 202 are symmetrically arranged about the vertical axis of the winding spindle 002, that is, the positions of the two are consistent.

[0043] In use: when the winding main shaft 002 drives the coiled package to continue to rotate, the film on the film roller 101 is continuously conveyed out from between the pressure roller one 102 and the pressure roller two 103 and is wound on the coiled package with the rotation of the winding main shaft 002, in the process, the film on the coiled package passes through the pressure roller three 202 and is further pressed by the pressure roller three 202 to further improve the close contact between the film and the surface of the coiled package and improve the quality of the winding and bundling.

[0044] Referring to Figure 6 and Figure 7 , in order to achieve automatic cutting of the film between the pressure roller two 103 and the coiled package after bundling, the lifting plate 201 is further fixed with a sawtooth knife 203; the sawtooth knife 203 is located between the pressure roller two 103 and the pressure roller three 202; wherein, after the film on the winding film roller 101 is wound and bundled on the coiled package, the support plate 100 can slide upward relative to the lifting plate 201.

[0045] In use: after the film on the winding film roller 101 is wound and bundled on the coiled package, the winding main shaft 002 stops rotating, at this time, the support plate 100 can be driven to move upward relative to the lifting plate 201, and the pressure roller one 102 and the pressure roller two 103 on the support plate 100 and the film therebetween move upward as a whole, while the pressure roller three 202 on the lifting plate 201 remains in place and is in close contact with the surface of the coiled package / film, in the process, the film between the pressure roller two 103 and the pressure roller three 202 changes position and is forced to be cut by the sawtooth edge of the sawtooth knife 203, which is easily broken in the process of contact with the film, thereby achieving automatic cutting of the film after the coiled package is bundled.

[0046] Referring to Figure 4 , Figure 6 and Figure 7 , in order to achieve the relative upward sliding of the support plate 100 relative to the lifting plate 201, the lifting plate 201 is further provided with a cylinder two 204; the support plate 100 is slidingly connected to the lifting plate 201, and the support plate 100 is fixed to the output shaft of the cylinder two 204.

[0047] In use: as Figure 4As shown, in the initial state of the cylinder two 204, the output shaft is in the state of contraction, and the pressure roller two 103 on the support plate 100 is at the same height as the pressure roller three 202 on the lifting plate 201; after the pressure roller two 103 and the pressure roller three 202 are tightly attached to the surface of the coiled packaging tape and form a film winding at the same time, the cylinder two 204 can be actuated, the output shaft of the cylinder two 204 is extended upwards to drive the support plate 100 to move upwards, so as to realize the relative position change of the pressure roller two 103 on the support plate 100 and the pressure roller three 202 on the lifting plate 201, and then the film between the pressure roller two 103 and the pressure roller three 202 is forced to contact the cutting edge of the saw blade 203, thereby forming the effect of automatic film cutting; in other words, after the winding film roller 101 is used for winding and bundling the coiled packaging tape, the effect of automatic film cutting can be formed, which is convenient for the next packaging tape winding and bundling.

[0048] Referring to Figure 5 and Figure 6 As shown, the saw blade 203 is arranged in a whole inclined manner, and the cutting edge thereof is adjacent to the pressure roller two 103; the cutting edge of the saw blade 203 is parallel to the horizontal tangent line of the pressure roller two 103, and the cutting edge is specifically located above the horizontal tangent line of the pressure roller two 103;

[0049] In use: on the basis that the pressure roller two 103 and the pressure roller three 202 are tightly attached to the coiled packaging tape and are used for film winding and bundling, the saw blade 203 at this time will not touch the coiled packaging tape / the film thereon; that is, when the coiled packaging tape is wound with the film by the winding spindle 002, the setting of the saw blade 203 will not interfere with (puncture) the coiled packaging tape / the film thereon, so as to ensure the normal operation of the film winding and bundling action.

[0050] Referring to Figure 3 , Figure 4 , Figure 8 , Figure 9 and Figure 10 As shown, the winding film roller 101 specifically comprises a roller body 1011, a mounting groove 1012, a rubber ring 1013, a pressing sleeve 1014 and an adjusting bolt 1015; the roller body 1011 is rotationally connected with the support plate 100; the roller body 1011 is provided with the mounting groove 1012, which is located at one end of the roller body 1011 away from the support plate 100; the rubber ring 1013 is sleeved on the roller body 1011 and located in the mounting groove 1012; the roller body 1011 is further sleeved with the pressing sleeve 1014 at the one end thereof away from the support plate 100, and the diameter of the pressing sleeve 1014 is consistent with that of the roller body 1011; the adjusting bolt 1015 is rotationally connected with the middle part of the pressing sleeve 1014, and one end of the adjusting bolt 1015 penetrating through the pressing sleeve 1014 is a threaded rod and is threadedly connected with the roller body 1011;

[0051] In use: when it is necessary to install / replace the film cylinder on the wrapping film roller 101, the coiled wrapping film cylinder is inserted into the roller body 1011, and then the operator can screw the adjusting bolt 1015, since the adjusting bolt 1015 is threadedly connected with the roller body 1011, the adjusting bolt 1015 can drive the compression sleeve 1014 rotationally connected therewith to move towards the roller body 1011 during screwing, and the rubber ring 1013 between the roller body 1011 and the compression sleeve 1014 is extruded to become flat (the initial cross section is circular), that is, the outer surface of the rubber ring 1013 is slightly radially convex to the installation groove 1012 after being flattened, and is in contact with the inner surface of the wrapping film cylinder, so as to tightly limit the wrapping film cylinder, which is convenient for the subsequent film unwinding, and can rotate together with the roller body 1011 supporting the position of the wrapping film cylinder, so as to ensure the stability of the film unwinding.

[0052] Conversely, when the empty paper cylinder after the wrapping film is used up is disassembled, the adjusting bolt 1015 can be reversed to move the compression sleeve 1014 away from the roller body 1011, at this time the rubber ring 1013 loses the limitation between the compression sleeve 1014 and the roller body 1011, and the extruded rubber ring 1013 can recover to the initial state through the elasticity of the material itself, at this time the rubber ring 1013 is more contracted into the installation groove 1012, which is convenient for the operator to pull out the empty paper cylinder on the roller body 1011.

[0053] Referring to Figure 4 As shown in the figure, the compression roller one 102, the compression roller two 103 and the compression roller three 202 are the same cylindrical structure, the lengths and diameters of the three are the same, and the three are attached with rubber material on the side surfaces, through the clamping of the rubber material, when the coiled main shaft 002 drives the coiled packing belt to rotate, the compression roller two 103 and the compression roller three 202 in contact with the coiled packing belt can stably rotate, and the quality of the film winding is improved; and when the compression roller two 103 rotates, the compression roller one 102 attached with the surface thereof can be driven to rotate, the opposite rotation of the two can ensure that the film on the wrapping film roller 101 is stably conveyed out and is wound and bundled to the surface of the coiled packing belt along with the rotation of the coiled packing belt, and the bundling of the coiled packing belt after winding is completed.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
