Description

Technical Field

[0001] The present application relates to the field of packaging equipment, and in particular to a film packaging equipment and a carbon fiber product production line. Background Art

[0002] At present, the most important steps in the packaging of polyacrylonitrile-based carbon fiber products are film covering and plastic sealing. When covering the product with film, due to the static electricity inside the heat shrink film, it is very easy to get stuck at the film head due to adsorption problems, causing the automatic packaging line to stop and start, affecting packaging efficiency and unnecessary loss of heat shrink film. At the same time, due to the high static electricity inside and outside the heat shrink film, the cutter often cuts the film incorrectly, resulting in poor heat shrink effect of subsequent products and "exposed meat" on the end surface, so it can only be reworked and re-sealed, which increases unnecessary labor.

[0038] Embodiment 1

[0039] See also Figures 1 to 4 As shown, the film packaging equipment provided by the present application includes an equipment body and an electrostatic removal device 104; the equipment body includes a feeding mechanism 101 and an opening mechanism, the feeding mechanism 101 is used to rotate the film material reel 103 so that the film material 102 (specifically a heat shrink film) wound on the film material reel 103 is unfolded and transported to the opening mechanism; the opening mechanism is used to open the film material 102 to form a cylindrical structure that is sleeved outside the product; the electrostatic removal device 104 is arranged between the feeding mechanism 101 and the opening mechanism.

[0040] Specifically, the film wrapping packaging device of the present application can be used to package polyacrylonitrile (PAN)-based carbon fiber products. A film material reel 103 is installed on the feeding mechanism 101 of the film wrapping packaging device, and the film material reel 103 is wound with film material 102. The film material 102 in the packaging state is stretched into a cylindrical shape so that the film material 102 can be wrapped around the product. In order to facilitate the winding and storage of the film material 102, the film material 102 on the film material reel 103 is in a state of two layers of film sticking to each other.

[0041] When packaging the product, it is necessary to unwind the film 102 on the film reel 103 and convey the film 102 to the opening mechanism to open the film 102 into a cylindrical shape so that it can be sleeved outside the product. When the film 102 is unwound and unfolded from the film reel 103, due to the static electricity between the film 102, the film 102 is easily adsorbed on the opening mechanism, which leads to the problem of film jamming, and has an adverse effect on the subsequent film 102 opening step. The present application sets an electrostatic removal device 104 between the feeding mechanism 101 and the opening mechanism to remove static electricity from the film 102 unwound and unfolded on the film reel 103, so that the film 102 is not easily adsorbed on the opening mechanism, so as to facilitate the subsequent opening mechanism to open the film 102 to sleeve outside the product, so that the entire packaging line can achieve continuous and stable operation, while reducing unnecessary loss of heat shrink film and unnecessary rework operations, and ultimately improving packaging efficiency and packaging quality.

[0042] In an optional scheme of this embodiment, the device body also includes a flattening mechanism; the flattening mechanism is located between the feeding mechanism 101 and the stretching mechanism, and the flattening mechanism is provided with a flattening gap, and the film material 102 unwound and unfolded on the film material reel 103 can pass through the flattening gap, so that the flattening gap presses and flattens the film material 102, which is convenient for subsequent stretching of the film material 102.

[0043] In an optional solution of this embodiment, the flattening mechanism includes a plurality of flattening roller assemblies 105 arranged at intervals, and the film material 102 passes through the plurality of flattening roller assemblies 105 in sequence. The flattening roller assembly 105 includes two conveying rollers 106 arranged opposite to each other, and a flattening gap is provided between the two conveying rollers 106. An electrostatic removal device 104 is provided at least one of between the flattening roller assembly 105 and the feeding mechanism 101, between two adjacent flattening roller assemblies 105, and between the flattening roller assembly 105 and the opening mechanism.

[0044] In this embodiment, if Figures 1 to 3 As shown, the flattening mechanism includes four flattening roller assemblies 105 arranged at intervals. The film material 102 passes through the flattening gaps of the four flattening roller assemblies 105 in sequence, which can achieve multiple pressure flattening effects on the film material 102, thereby improving the flattening effect. In addition, the four flattening roller assemblies 105 arranged at intervals can achieve a tensioning effect on the film material 102, which is more conducive to flattening the film material 102.

[0045] Furthermore, the four flattening roller assemblies 105 arranged at intervals form a tortuous conveying path, which occupies less space. On the conveying path of the film material 102, the first flattening roller assembly 105 is opposite to the unfolding position of the film material 102 of the film material reel 103 to form a horizontal first conveying section; the second flattening roller assembly 105 is arranged at intervals with the first flattening roller assembly 105 in the vertical direction to form a vertically upward second conveying section; the third flattening roller assembly 105 is arranged at intervals with the second flattening roller assembly 105 in the horizontal direction to form a horizontal third conveying section; the fourth flattening roller assembly 105 is arranged at intervals with the third flattening roller assembly 105 in the vertical direction to form a vertically downward fourth conveying section; the opening mechanism is arranged at intervals with the fourth flattening roller assembly 105 in the vertical direction to form a vertically downward fifth conveying section. The static removal device 104 can be arranged on any of the above conveying sections to achieve static removal of the film material 102 before opening.

[0046] In an optional solution of this embodiment, the device body includes a chassis 107; the flattening mechanism is installed on the side wall of the chassis 107, and an electrostatic removal device 104 is arranged between two adjacent flattening roller assemblies 105; a support beam is arranged on the side wall of the chassis 107, and the electrostatic removal device 104 can be detachably installed on the support beam.

[0047] In this embodiment, if Figures 1 to 3 As shown, the static electricity removal device 104 is arranged between the second flattening roller assembly 105 and the third flattening roller assembly 105, so that the static electricity removal device 104 can be connected to the side wall of the chassis 107, thereby realizing the installation and fixation of the static electricity removal device 104. Of course, the static electricity removal device 104 can also be arranged between the first flattening roller assembly 105 and the second flattening roller assembly 105, or between the third flattening roller assembly 105 and the fourth flattening roller assembly 105 (the space is relatively small and inconvenient to install), and the static electricity removal device 104 can also be installed and fixed by using the side wall of the chassis 107.

[0048] Although the area between the fourth flattening roller assembly 105 and the stretching mechanism is also opposite to the side wall of the chassis 107, the film material 102 in this area will be gradually stretched during transportation, and the static electricity removal effect of the static electricity removal device 104 on the side of the film material 102 away from the static electricity removal device 104 is relatively poor.

[0049] Optionally, the support beam may be an angle steel or an I-beam, and the static electricity removal device 104 may be detachably mounted on the plane of the support beam. For example, the static electricity removal device 104 may be tied to the support beam using a cable tie.

[0050] In an optional solution of this embodiment, the expansion mechanism includes an expansion member 108 and a film cutting knife 109; the film material 102 is sleeved on the outside of the expansion member 108, and the film cutting knife 109 is arranged around the expansion member 108 to cut the film material 102; along the conveying path of the film material 102, an electrostatic removal device 104 is arranged downstream of the film cutting knife 109.

[0051] In this embodiment, during the film packaging of the product, there is a problem that the film cutting knife 109 may have uneven film cutting edges due to the high static electricity generated by the heat shrink film, which affects the subsequent heat shrinking effect. The film jamming problem may cause the entire packaging line to be interrupted, affecting the product packaging efficiency. The present application provides a static electricity removal device 104 downstream of the film cutting knife 109 to remove static electricity from the film material 102 at this position, avoiding the problems of film jamming and uneven film cutting. The heat shrink film after cutting can freely fall onto the product wire drum, thereby improving the heat shrinking effect.

[0052] In the optional solution of this embodiment, Figure 2 As shown, the film cutting knife 109 includes a cutting blade 110 and a mounting plate 111; the mounting plate 111 is provided with a through hole, and the cutting blade 110 is surrounded in the through hole; static electricity removal devices 104 are provided on both sides of the support member 108 that are opposite to each other in the circumferential direction, which can remove static electricity from the film material 102 from both sides of the film material 102, achieving better effect.

[0053] Furthermore, the static electricity removal device 104 is detachably connected to the mounting plate 111. Optionally, a mounting hole can be opened on the mounting plate 111, and the static electricity removal device 104 can be tied to the mounting hole with a cable tie; or a bracket can be welded on the mounting plate 111, and the static electricity removal device 104 can be detachably installed on the bracket.

[0054] In the optional scheme of this embodiment, the static electricity removal device 104 is a static electricity removal ion wind rod; the static electricity removal ion wind rod is connected to the air source through the connecting hole 113 to blow ion wind to the film material 102; the blowing range of the static electricity removal ion wind rod is adapted to the width of the film material 102, and static electricity can be removed from various parts of the film material 102, with better effect. Specifically, the static electricity removal ion wind rod uses compressed air as the air source, and the pressure is 6 bar. The multiple blowing holes 112 of the static electricity removal ion wind rod are directly facing the surface of the heat shrink film to neutralize the charges on the surface and inside of the heat shrink film, thereby achieving the purpose of eliminating static electricity.

[0055] Embodiment 2

[0056] The film packaging equipment in the second embodiment is an improvement on the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0057] In an optional scheme of this embodiment, the destaticizing ion wind rod is provided with a detection module and a warning light, and the warning light is electrically connected to the detection module; the detection module is used to detect the discharge condition in the packaging line area, so as to cut off the power supply when an abnormal discharge condition is detected, and control the warning light to light up.

[0058] In this embodiment, specifically, the destaticizing ion wind rod can adopt a 24V low-voltage pulsed DC method, with a built-in high-voltage generator, which can effectively and quickly eliminate static electricity inside and outside the heat shrink film over a large range. Because there may be floating carbon hair in the air in the automatic packaging line area, when the detection module detects abnormal discharge, it can automatically sound an alarm and cut off the high-voltage power supply. The destaticizing ion wind rod is provided with a plurality of blowing holes 112. The length of the destaticizing ion wind rod is set according to the width of the film material 102, and the corresponding number of blowing holes 112 is set. If the status light of the warning light is "green", it means that the destaticizing ion wind rod is working normally. If the status light is "red", it means that the destaticizing ion wind rod is abnormally not working. The operator needs to unplug the PU air pipe in time, deal with the hair, and then plug it in to restore to normal.
