[0015] Preferably, a feeder is installed at the feed end of the blow molding machine, and the winding assembly includes a collecting rack and a collecting roller, and the collecting roller is installed at the center of the two groups of collecting racks.
[0016] Preferably, a processing method of a PE protective film processing device comprises the following steps:
[0017] Step 1: First, the mixed film material is fed into the feeder, and then the film material is fed into the blow molding machine through the feeder. The blow molding machine processes the film material, melts the film material and pulls it upward. At this time, the thin-walled tubular film material is pulled into the film outlet slot, and then the thin-walled tubular film material is squeezed by the film pressing roller. Then the PE film slides along the film falling slot. At this time, the first support roller supports the PE film, and then the supported PE film is rebuilt on the top of the second support roller, thereby reserving the space between the PE film and the blow molding machine;
[0018] Step 2: Then, during the movement of the PE film, the PE film is interlaced with the first film winding roller and the second film winding roller in the coil assembly. At this time, the first film winding roller and the second film winding roller adjust the position between the first film winding roller and the second film winding roller through the adjustment groove, so that the PE film can be continuously tightened, and the outer surface of the PE film is tightened during the transportation process;
[0019] Step 3: When the PE film is fed into the film breaking positioning structure, the PE film is preferentially connected to the film pressing assembly. At this time, the clamping roller in the film pressing assembly clamps the PE film. At this time, the PE film is stably fed into the film delivery assembly through the film pressing assembly. During the transportation of the PE film inside the film delivery assembly, the PE film is restricted by the film pressing assembly, so that after the PE film has the problem of film breaking, the film pressing assembly continuously adjusts the height position of the PE film through the clamping roller controlled by the second motor room, so that the PE film is still stably transported into the film delivery assembly;
[0020] Step 4: When the PE film enters the interior of the film delivery assembly, the PE film is clamped by the main positioning roller and the auxiliary positioning roller. Then, the PE film support assembly drives the electrostatic adsorption roller to support the lower film position of the PE film through the inclined bracket connected to the steering bracket. Then, while the electrostatic adsorption roller supports the PE film, the residual static electricity of the PE film itself is adsorbed by the electrostatic adsorption roller.
[0021] Step 5: After the PE film passes through the moving position of the film cutting positioning structure, the PE film moves into the interior of the film cutting pressing component, and then the PE film passes through the film cutting pressing component and enters the interior of the film feeding component, so that the film feeding component transports the PE film into the interior of the winding component, thereby completing the winding of the PE film;
[0022] Step 6: At this time, the main positioning roller and the auxiliary positioning roller connected to the PE film in the film breaking and pressing assembly are staggered to tighten the film, which is used to apply tension to the film regularly. When the PE film breaks due to internal unevenness due to quality problems, the PE film breaks within the range of the film breaking reserved room. At this time, the first rotating bracket drives the directional roller to rotate along the axis, and the outer surface of the directional roller falls on the upper part of the PE film. At the same time, the steering bracket in the PE film support assembly drives the electrostatic adsorption roller to rotate along the axis through the inclined bracket, and the directional roller and the electrostatic adsorption roller are in contact. At this time, the directional roller and the electrostatic adsorption roller clamped The tilt angle is 20°. At this time, the third motor room of the jet assembly drives the main jet head and the auxiliary jet head of the rotating plate to turn 90°. At this time, the main jet head and the auxiliary jet head run simultaneously and blow the PE film clamped by the directional roller and the electrostatic adsorption roller upward. During the blowing process, the rotating plate is driven by the third motor room to rotate, so that the main jet head and the auxiliary jet head on the rotating plate rotate outward 10°, so that the fracture of the PE film can be continuously blown by the main jet head and the auxiliary jet head to the fracture range of the film delivery assembly. At this time, the fracture position of the PE film will continuously fall at the center of the film-breaking reserved chamber;
[0023] Step seven: When the PE film breaks, the first film winding roller and the second film winding roller in the coil assembly are continuously tightened, so that the space reserved by the first film winding roller and the second film winding roller is continuously tightened, thereby reducing the length of the PE film during the conveying process, and the second motor room drives the clamping roller to tighten, thereby maintaining the tension of the PE film itself during the breaking process.
[0024] Technical effects and advantages of this application:
[0025] 1. Compared with the prior art, the processing equipment and the processing method of the PE protective film are as follows: when the PE film enters the film conveying assembly, it is clamped by the main positioning roller and the auxiliary positioning roller, and then the PE film support assembly drives the electrostatic adsorption roller through the inclined bracket to support and adsorb the lower part of the PE film, and eliminate the static electricity on the PE film. If the PE film breaks, the first film winding roller and the second film winding roller in the coil assembly will automatically tighten to reduce the length of the PE film during transportation, and at the same time, the second motor drives the clamping roller to tighten to keep the PE film in a tensioned state when it breaks.
[0026] 2. Compared with the prior art, the processing equipment and the processing method of the PE protective film are used to tighten the film by staggering the main positioning roller and the auxiliary positioning roller connected to the PE film in the film breaking and pressing assembly, so as to apply tension to the film regularly. When the PE film breaks due to internal unevenness due to quality problems, the PE film breaks within the range of the film breaking reserved chamber. At this time, the first rotating bracket drives the directional roller to rotate along the axis, and the outer surface of the directional roller falls on the upper position of the PE film. At the same time, the steering bracket in the PE film support assembly drives the electrostatic adsorption roller to rotate along the axis through the inclined bracket, and the directional roller and the electrostatic adsorption roller are in contact. At this time, the inclined angle clamped by the directional roller and the electrostatic adsorption roller is 20°, and the third electric The machine room drives the main jet head and the auxiliary jet head of the rotating plate to turn 90°. At this time, the main jet head and the auxiliary jet head run at the same time and blow the PE film clamped by the directional roller and the electrostatic adsorption roller upward. During the blowing process, the rotating plate is driven by the third motor room to rotate, so that the main jet head and the auxiliary jet head on the rotating plate are rotated outward by 10°, so that the fracture of the PE film can be continuously blown by the main jet head and the auxiliary jet head to the fracture range of the film delivery component. At this time, the fracture position of the PE film will continuously fall on the center of the broken film reserved chamber, so that even if the film is broken, the fracture position of the broken PE film can still be unfolded by the broken film positioning component, so as to facilitate the resetting of the PE film.
[0027] 3. Compared with the prior art, the processing equipment and method of the PE protective film adopts a coiling assembly. When the PE film breaks, the coiling assembly passes through the first film winding roller; 20. The second film winding roller adjusts the conveying length of the film, thereby extending the output length of the PE film, thereby reducing the length of the PE film being conveyed outward, thereby reducing the damaged length of the PE film.

DETAILED DESCRIPTION
[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0039] Example 1
[0040] As attached Figures 1 to 9The processing equipment of a PE protective film shown in the figure comprises a blow molding machine 1, a film cutting positioning structure 4 and a film cutting pressing component 9, and is characterized in that: a coil component 3 is arranged on the side of the blow molding machine 1, and a film cutting positioning structure 4 is arranged on the side of the coil component 3 away from the blow molding machine 1, and a film cutting pressing component 9 is arranged on the side of the film cutting positioning structure 4 away from the coil component 3, and a film cutting reserved chamber 8 is arranged at the center of the film cutting positioning structure 4 and the film cutting pressing component 9, and a film feeding component 10 is arranged on the side of the film cutting pressing component 9 away from the film cutting positioning structure 4, and a film feeding component 10 is arranged on the side of the film feeding component 10 away from the film cutting pressing component 9 The winding component 11, and the film cutting positioning structure 4 includes a second mounting bracket 5, a film pressing component 6 and a film feeding component 7, and the film pressing component 6 is fixedly arranged on the side of the second mounting bracket 5, and the film feeding component 7 is arranged on the side of the film pressing component 6 away from the blow molding machine 1, and the film feeding component 7 includes a fixed bracket 29, a fixed base 35, an injection component 36 and a PE film supporting component 37, and the fixed base 35 is fixedly arranged on the bottom of the fixed bracket 29, and the injection component 36 is arranged on the side of the fixed bracket 29 away from the film pressing component 6, and the PE film supporting component 37 is fixedly arranged on the top of the injection component 36.
[0041] Among them, when the PE film is being processed, a film-breaking reserved chamber 8 is set at the center of the film-breaking positioning structure 4 and the film-breaking pressing component 9. At this time, the PE film is stretched regularly by the film-breaking pressing component 9. This stretching does not exceed the limit that the PE film itself can withstand. It is only used for regular detection. The position of the PE film break can be directly and accurately confirmed, so that the quality of the PE film can be detected in real time. When the quality of the PE film does not meet the standard, the position of the PE film break will be determined at the position of the film-breaking reserved chamber 8, so that the PE film break position can be directly monitored. And through the film-breaking pressing component 9, the processing personnel can arrive at the scene in advance when the film-breaking pressing component 9 is processing the PE film, and quickly process the broken PE film. At the same time, the coil component 3 and the film pressing component 6 in the film-breaking positioning structure 4 process the conveying length of the PE film, so that the length of the PE film during the conveying process is extended and the length of the PE film wasted after the PE film is broken is reduced.

During the transportation of the PE film in the film delivery assembly 7, the PE film is restricted by the film pressing assembly 6, so that after the PE film has the problem of film breaking, the film pressing assembly 6 continuously adjusts the height position of the PE film through the clamping roller 27 controlled by the second motor chamber 28, so that the PE film is still stably transported into the film delivery assembly 7;
[0056] Step 4: When the PE film enters the film delivery assembly 7, the PE film is clamped by the main positioning roller 30 and the auxiliary positioning roller 31. Then the PE film support assembly 37 drives the electrostatic adsorption roller 42 to support the lower film position of the PE film through the inclined bracket 47 connected to the steering bracket 48. Then, while the electrostatic adsorption roller 42 supports the PE film, the static electricity remaining in the PE film itself is adsorbed by the electrostatic adsorption roller 42.
[0057] Step 5: After the PE film passes through the film cutting positioning structure 4, the PE film moves into the film cutting and clamping assembly 9, and then the PE film passes through the film cutting and clamping assembly 9 and enters the film feeding assembly 10, so that the film feeding assembly 10 conveys the PE film into the winding assembly 11, thereby completing the winding of the PE film;
[0058] Step 6: At this time, the main positioning roller 30 and the auxiliary positioning roller 31 connected to the PE film in the film-breaking pressing component 9 are staggered to tighten the film, which is used to apply tension to the film regularly. When the PE film breaks due to internal unevenness due to quality problems, the PE film breaks within the range of the film-breaking reserved chamber 8. At this time, the first rotating bracket 33 drives the directional roller 34 to rotate along the axis, and makes the outer surface of the directional roller 34 fit the upper position of the PE film. At the same time, the steering bracket 48 in the PE film support component 37 drives the electrostatic adsorption roller 42 to rotate along the axis through the inclined bracket 47, and makes the directional roller 34 and the electrostatic adsorption roller 42 contact. At this time, the inclined bracket 47 clamped by the directional roller 34 and the electrostatic adsorption roller 42 The angle is 20°. At this time, the third motor chamber 49 of the jet assembly 36 drives the main jet head 51 and the auxiliary jet head 40 of the rotating plate 50 to turn 90°. At this time, the main jet head 51 and the auxiliary jet head 40 run simultaneously and blow the PE film clamped by the directional roller 34 and the electrostatic adsorption roller 42 upward. During the blowing process, the rotating plate 50 is driven by the third motor chamber 49 to rotate, so that the main jet head 51 and the auxiliary jet head 40 on the rotating plate 50 rotate outward by 10°, so that the fracture of the PE film can be continuously blown by the main jet head 51 and the auxiliary jet head 40 to the fracture range of the film delivery assembly 7. At this time, the fracture position of the PE film will continuously fall on the center of the film-breaking reserved chamber 8;
[0059] Step seven: At the same time when the PE film breaks, the first film winding roller 19 and the second film winding roller 20 in the coil assembly 3 are continuously tightened, so that the space reserved by the first film winding roller 19 and the second film winding roller 20 is continuously tightened, thereby reducing the length of the PE film during the conveying process, and the second motor chamber 28 drives the clamping roller 27 to tighten, thereby maintaining the tension of the PE film during the PE film's operation during the breaking process.
[0060] The working process of the present application is as follows: first, the mixed film material is fed into the feeder 2, and then the film material is fed into the blow molding machine 1 through the feeder 2, and then the blow molding machine 1 processes the film material, melts the film material and pulls it upward, at this time, the thin-walled tubular film material is pulled into the film outlet groove 12, and then the thin-walled tubular film material is extruded by the film pressing roller 13, and then the PE film slides along the film falling groove 14, at this time, the first support roller 15 supports the PE film, and then the supported PE film is rebuilt above the second support roller 17, so as to reserve the space between the PE film and the blow molding machine 1;
[0061] Step 2: Then, during the movement of the PE film, the PE film is interlaced with the first film winding roller 19 and the second film winding roller 20 in the coil assembly 3. At this time, the first film winding roller 19 and the second film winding roller 20 adjust the position between the first film winding roller 19 and the second film winding roller 20 through the adjustment groove 21, so that the PE film can be continuously tightened and the outer surface of the PE film can be tightened during the transportation process;
[0062] Then, when the PE film is fed into the film breaking positioning structure 4, the PE film is preferentially connected to the film pressing assembly 6, and the clamping roller 27 in the film pressing assembly 6 clamps the PE film. At this time, the PE film is stably fed into the film delivery assembly 7 through the film pressing assembly 6. During the transportation of the PE film inside the film delivery assembly 7, the PE film is restricted by the film pressing assembly 6, so that after the PE film has the problem of film breaking, the film pressing assembly 6 continuously adjusts the height position of the PE film through the clamping roller 27 controlled by the second motor chamber 28, so that the PE film is still stably transported into the film delivery assembly 7;
[0063] Then when the PE film enters the interior of the film delivery assembly 7, the PE film is clamped by the main positioning roller 30 and the auxiliary positioning roller 31, and then the PE film support assembly 37 drives the electrostatic adsorption roller 42 to support the lower film position of the PE film through the inclined bracket 47 connected to the steering bracket 48, and then the electrostatic adsorption roller 42 supports the PE film while the static electricity remaining in the PE film itself is adsorbed by the electrostatic adsorption roller 42;
[0064] Then, after the PE film passes through the film cutting positioning structure 4, the PE film moves into the interior of the film cutting pressing component 9, and then the PE film passes through the film cutting pressing component 9 and enters the interior of the film feeding component 10, so that the film feeding component 10 conveys the PE film into the interior of the winding component 11, thereby completing the winding of the PE film;
[0065] At this time, the main positioning roller 30 and the auxiliary positioning roller 31 connected to the PE film in the film-breaking clamping assembly 9 are staggered to tighten the film, so as to apply tension to the film regularly. When the PE film breaks due to internal unevenness due to quality problems, the PE film breaks within the range of the film-breaking reserved chamber 8. At this time, the first rotating bracket 33 drives the directional roller 34 to rotate along the axis, and makes the outer surface of the directional roller 34 stick to the upper position of the PE film. At the same time, the steering bracket 48 in the PE film supporting assembly 37 drives the electrostatic adsorption roller 42 to rotate along the axis through the inclined bracket 47, and makes the directional roller 34 and the electrostatic adsorption roller 42 contact. At this time, the inclination angle clamped by the directional roller 34 and the electrostatic adsorption roller 42 is 20°, at this time, the third motor chamber 49 of the jet assembly 36 drives the main jet head 51 and the auxiliary jet head 40 of the rotating plate 50 to turn 90°, and at this time, the main jet head 51 and the auxiliary jet head 40 run simultaneously and blow the PE film clamped by the directional roller 34 and the electrostatic adsorption roller 42 upward. During the blowing process, the rotating plate 50 is driven by the third motor chamber 49 to rotate, so that the main jet head 51 and the auxiliary jet head 40 on the rotating plate 50 are rotated outward by 10°, so that the fracture of the PE film can be continuously blown by the main jet head 51 and the auxiliary jet head 40 to the fracture range of the film delivery assembly 7, and at this time, the fracture position of the PE film will continuously fall at the center of the film-breaking reserved chamber 8;
[0066] At the same time, when the PE film breaks, the first film winding roller 19 and the second film winding roller 20 in the coil assembly 3 are continuously tightened, so that the space reserved by the first film winding roller 19 and the second film winding roller 20 is continuously tightened, thereby reducing the length of the PE film during the transportation process, and the second motor chamber 28 drives the clamping roller 27 to tighten, thereby maintaining the tension of the PE film during the breaking process. The above is the working principle of the processing equipment and processing method of the PE protective film.
