Description

Technical Field

[0001] The utility model relates to the technical field of film production, in particular to an automatic line drawing device for nylon film. Background Art

[0002] Nylon film is a very tough material. Nylon film has good transparency, good gloss, high tensile strength, good heat resistance, cold resistance, oil resistance, organic solvent resistance, wear resistance, puncture resistance, and is relatively soft. It has excellent oxygen barrier properties, but poor water vapor barrier properties, high moisture absorption and moisture permeability, and poor heat sealing properties.

[0003] Among them, nylon film with smaller arc effect is convenient for later processing and use. Therefore, in the trial production stage of nylon film, it is necessary to adjust the transverse stretching parameters of nylon film according to the arc effect of nylon film. Specifically, before the nylon film is transversely stretched, the worker uses a marking pen to draw a straight line on the nylon film; after the nylon film is transversely stretched, the deformation of the straight line on the nylon film can be used to roughly understand the arc effect of the nylon film.

[0004] However, it is difficult to draw lines on the surface of nylon film manually, and it is impossible to ensure that the drawn lines are straight, which affects the deformation of the lines observed later. In addition, in the process of drawing lines, the sharp pen tip is easy to scratch the surface of the nylon film, which affects the subsequent stretching effect. Utility Model Content

[0005] The utility model aims to provide a nylon film automatic marking device, which can realize horizontal marking on the nylon film and effectively avoid scratches on the surface of the nylon film.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0008] The elastic line is in a taut state and is laterally placed above the nylon film, and the two ends of the elastic line protrude from the edges of both sides of the nylon film respectively;

[0009] An ink cartridge is provided on the lifting end of the lifting assembly; the elastic wire passes through the ink cartridge, and its two ends are respectively wound on corresponding winding drums, and the winding drums are fixed on the lifting end of the lifting assembly;

[0010] The clamping mechanism is arranged above the middle section of the elastic line.

[0011] Through the cooperation between the lifting component and the clamping mechanism, a straight ink line is ejected on the upper surface of the nylon film using an elastic line, so as to realize horizontal marking on the nylon film and effectively protect the surface of the nylon film; through the cooperation between the ink cartridge and the winding reel, the marking liquid is attached to the elastic line.

[0012] As a further solution of the utility model, the lifting assembly includes two lifting mechanisms, which are symmetrically distributed on both sides of the nylon film, and the lifting ends thereof are respectively equipped with the winding disks, and the ink cartridge is fixed on the lifting end of one of the lifting mechanisms and is located between the two winding disks. With the above solution, the elastic wire is driven upward to the clamping area of ​​the clamping mechanism by the two lifting mechanisms to prevent the clamping mechanism from accidentally touching the nylon film when clamping, thereby effectively protecting the nylon film.

[0013] As a further solution of the utility model, a limiting frame is respectively provided on the lifting ends of the two lifting mechanisms, one end of the elastic wire passes through one limiting frame and is wound on the corresponding winding drum, and the other end of the elastic wire passes through the other limiting frame and the ink cartridge in sequence and is wound on the corresponding winding drum. With the above solution, the elastic wire is limited by the two limiting frames so that the elastic wire placed directly above the nylon film is arranged horizontally.

[0014] As a further solution of the utility model, the clamping mechanism is a two-finger clamp. The above solution is adopted to effectively clamp the ink line.

[0015] As a further solution of the utility model, a sponge soaked with a marking liquid is provided in the inner cavity of the ink cartridge, and the elastic line passes through the sponge. The above solution is adopted so that the marking liquid is effectively attached to the elastic line.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] A nylon film automatic line drawing device, please refer to Figure 1 and Figure 2 As shown, it includes an elastic line 1, a lifting component 2 and a clamping mechanism 3 for clamping the elastic line 1. The nylon film 7 is longitudinally conveyed and circulated by a conveying roller 8. The elastic line 1 is in a taut state and is laterally placed above the nylon film 7. The two ends of the elastic line 1 protrude from the edges on both sides of the nylon film 7 respectively. An ink cartridge 4 is provided on the lifting end of the lifting component 2. A sponge soaked in a marking liquid is provided in the inner cavity of the ink cartridge 4. The elastic line 1 passes through the ink cartridge 4, and its two ends are respectively wound on corresponding winding reels. The winding reel is fixed to the lifting end of the lifting component 2. The clamping mechanism 3 is arranged above the middle section of the elastic line 1. Among them, the elastic line 1 passes through the sponge in the ink cartridge 4 so that the marking liquid is attached to the elastic line 1.

[0032] In this embodiment, the clamping mechanism 3 is a two-finger clamping claw, which is used to effectively clamp the elastic line 1. The clamping mechanism 3 is fixed on the support frame 5.

[0033] In this embodiment, the elastic line 1 is a cotton line, which is convenient for attaching the marking liquid.

[0034] In this embodiment, the winding drum is driven to rotate by a driving motor, thereby realizing the winding and unwinding of the winding drum.

[0035] Furthermore, the marking liquid is high temperature resistant ink to ensure that the ink line on the nylon film 7 is still colored after the nylon film 7 flows to the high temperature area.

[0036] The utility model uses the cooperation of the lifting component 2 and the clamping mechanism 3 to use the elastic line 1 to pop out a straight ink line on the upper surface of the nylon film 7, thereby realizing the horizontal drawing of the nylon film 7, and preventing the surface of the nylon film 7 from being scratched by the sharp pen tip; through the cooperation between the ink cartridge 4 and the winding drum, the marking liquid is attached to the elastic line 1. Specifically, the lateral movement of the elastic line 1 is realized by the cooperation of the winding and releasing of the two winding drums, and at the same time, the elastic line 1 passes through the ink cartridge 4 in a taut state, so that the marking liquid is attached to the elastic line 1 passing through the ink cartridge 4, so that the elastic line 1 will pop out the ink line on the upper surface of the nylon film 7 later.

[0037] See also Figure 2 As shown, the lifting assembly 2 includes two lifting mechanisms. Both lifting mechanisms are fixed on the ground, and the lifting ends of both are set upward and move synchronously. The two lifting mechanisms are respectively a first lifting mechanism 21a and a second lifting mechanism 21b. The first lifting mechanism 21a and the second lifting mechanism 21b are symmetrically distributed on both sides of the nylon film 7. Specifically, the first lifting mechanism 21a is located on the left side of the nylon film 7, and the second lifting mechanism 21b is located on the right side of the nylon film 7. The lifting end of the first lifting mechanism 21a is equipped with a first winding drum 6a and an ink cartridge 4, and the lifting end of the second lifting mechanism 21b is equipped with a second winding drum 6b. The ink cartridge 4 is located between the two winding drums.

[0038] In this embodiment, the lifting mechanism is a cylinder.

[0039] In this embodiment, the first winding drum 6a and the ink cartridge 4 are assembled on the top of the first lifting mechanism 21a through the corresponding support plate 22, and the second winding drum 6b is assembled on the top of the second lifting mechanism 21b through the corresponding support plate 22.

[0040] When the elastic line 1 needs to be attached with marking liquid, the first winding drum 6a releases the line, and the second winding drum 6b reels the line, so that the elastic line 1 directly above the nylon film 7 moves to the right, that is, the elastic line 1 passes into the inner cavity of the ink cartridge 4 from the left side of the ink cartridge 4, and the marking liquid is attached to the elastic line 1 passing through the inner cavity of the ink cartridge 4. When the elastic line 1 directly above the nylon film 7 is attached with marking liquid, the two winding drums stop running, that is, the elastic line 1 directly above the nylon film 7 stops moving to the right.

[0041] After the nylon film automatic line drawing device has drawn lines for many times, the marking liquid attached to the elastic line 1 will decrease, and then the elastic line 1 cannot draw a clear ink line. At this time, the first winding drum 6a is winding up, and the second winding drum 6b is unwinding, so that the elastic line 1 just above the nylon film 7 moves to the left, so that the elastic line 1 with too little marking liquid attached is rewound on the first winding drum 6a. Then, the above-mentioned operation of attaching marking liquid to the elastic line 1 is repeated, that is, the first winding drum 6a is unwinding, and the second winding drum 6b is winding up.

[0042] In the process of the elastic line 1 moving, the elastic line 1 is always in a taut state.

[0043] Since the two ends of the elastic line 1 are respectively wound on the corresponding winding drum, the positions of the two ends of the elastic line 1 may be inconsistent in horizontal height after the winding drum is wound and released, that is, it is impossible to ensure that the elastic line 1 above the nylon film 7 is horizontally set, and it is impossible to ensure that the elastic line 1 directly above the nylon film 7 is perpendicular to the length direction of the nylon film 7. Therefore, please refer to Figure 2 and Figure 6 As shown, a limiting frame 23 is respectively provided on the lifting end of the two lifting mechanisms to limit the position of the elastic line 1. One end of the elastic line 1 passes through the limiting hole of one limiting frame 23 and is wound on the corresponding winding drum. The other end of the elastic line 1 passes through the limiting hole of the other limiting frame 23 and the ink cartridge 4 in sequence and is wound on the corresponding winding drum. The elastic line 1 is limited by the limiting holes of the two limiting frames 23 so that the elastic line 1 located above the nylon film 7 is horizontally arranged and perpendicular to the length direction of the nylon film 7.

[0044] In this embodiment, the limiting frames 23 are vertically fixed on the top of the corresponding lifting mechanism through the support plate 22, and the two limiting frames 23 are symmetrically arranged.

[0045] The specific steps of drawing a line with the spring line 1 attached with the marking liquid are as follows:

[0046] See also Figure 2 As shown, the elastic line 1 is driven to rise as a whole by the lifting assembly 2 until it moves to the clamping area of ​​the clamping mechanism 3; at this time, as shown in FIG. Figure 3 As shown, the height distance between the elastic line 1 and the upper surface of the nylon film 7 is 30 mm to 50 mm;

[0047] The clamping mechanism 3 partially clamps the middle section of the elastic line 1. Figure 4 As shown;

[0048] The two ends of the elastic line 1 are driven to move downward simultaneously by the lifting assembly 2 until the two ends of the elastic line 1 are slightly higher than the upper surface of the nylon film 7; at this time, Figure 5 As shown, the height distance between the two ends of the elastic line 1 and the upper surface of the nylon film 7 is 4 mm to 8 mm;

[0049] The clamping mechanism 3 releases the elastic line 1, and the elastic line 1 uses the marking liquid attached to its surface to pop out a straight ink line on the upper surface of the nylon film 7;

[0050] After the line drawing is completed, the lifting component 2 drives the two ends of the elastic line 1 to move upward at the same time, so that the height distance between the elastic line 1 and the upper surface of the nylon film 7 is 15mm to 20mm, that is, the elastic line 1 is away from the nylon film 7, effectively avoiding accidental contact between the elastic line 1 and the nylon film 7.

[0051] The lifting assembly 2 drives the elastic line 1 to move upward to the clamping area of ​​the clamping mechanism 3 to prevent the clamping mechanism 3 from accidentally touching the nylon film 7 when clamping the elastic line 1, thereby effectively protecting the nylon film 7.

[0052] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of patent protection of the utility model.
