Description

Technical Field

[0001] The utility model belongs to the technical field of film processing, and specifically relates to an automatic material collecting device for automotive black film. Background Technique

[0002] A film is a thin and soft transparent sheet. It is made of plastic, adhesive, rubber or other materials.

[0003] Decorative black film is a high-tech pressure-sensitive adhesive product designed for special industrial applications.

[0004] In the automotive industry, it is commonly used in door structures or window pillars of vehicles to replace the decorative function of paint and enhance the visual effect of the windshield and window frame.

[0005] Decorative black film is composed of a stable calendered polyvinyl chloride film, an acrylic pressure-sensitive adhesive, and a bubble-free silicone-coated release paper. Due to the different surface states of the film surface, it can be divided into: matte film, frosted film, fine frosted film, and high-gloss film.

[0006] With the progress of industry, there are more and more production equipment related to automotive black film, among which there is an automatic material collecting device for automotive black film used for sorting and collecting the regular black film after being processed by a die-cutting machine.

[0007] The existing patent authorization announcement number is CN205772242U, and the utility model patent with the patent name of a plastic film material collecting device records including a material collecting bracket, a material dragging mechanism, and a material receiving mechanism arranged below the material dragging mechanism; the material receiving mechanism includes a lifting seat movably arranged on the material collecting bracket, a lifting seat driving mechanism for driving the lifting seat to lift, a material receiving plate rotatably arranged on the lifting seat, and a discharging driving mechanism for driving the material receiving plate to rotate and discharge materials. The material dragging mechanism is used to drag the material above the material receiving plate. The structure of the utility model is compact. It can realize automatic material collection for the film wound on a paper core tube. Its material collection is safe and reliable, replacing manual operation, improving production efficiency, and reducing labor costs.

[0008] The device described in the above patent has certain drawbacks when in use. The plastic film material collecting device described above is used for winding and collecting the film. However, for automotive black film, it is relatively hard as a whole, and after being processed by a die-cutting machine, it becomes a regular rectangle, and it is not suitable for winding and collecting. Therefore, in the existing solution, a material collecting frame body is usually placed at the end of the die-cutting machine, and the die-cut automotive black film directly falls onto the frame body;

[0009] When receiving materials in this way, the black film is scattered and needs to be sorted out later, which is rather troublesome. Moreover, when receiving materials, if the frame is relatively low, the black film is more scattered and prone to bending and folding, affecting subsequent processing. If the frame is relatively high, after receiving several black films, the height of the stacked black film is higher than the height of the die-cutting machine. At this time, it is necessary to manually remove the black film immediately, which is rather troublesome and does not meet the usage requirements of people.

[0010] In summary, there are certain drawbacks in the existing film receiving devices during use, which do not meet the usage requirements of people. Therefore, we propose an automatic receiving device for automotive black films. Utility Model Content

Detailed implementation manners

[0065] By providing an automatic material receiving device for automotive black film in the embodiments of the present application, the problems in the prior art that in the actual use of the existing automatic material receiving devices for automotive black film, during material receiving, the black film is scattered, requiring subsequent sorting, which is rather troublesome, and during material receiving, if the frame is relatively low, the black film is more scattered and prone to bending and folding, affecting subsequent processing, and if the frame is relatively high, after receiving several black films, the height of the stacked black film is higher than the height of the die-cutting machine, and at this time, it is necessary to manually remove the black film immediately, which is rather troublesome and costly, are solved.

[0066] Embodiment 1:

[0067] An automatic material receiving device for automotive black film, as Figure 1 - Figure 8 shown, which is used for receiving the cut and regular-shaped automotive black film, and includes a support frame body 1 and a material receiving assembly 2;

[0068] A constant force lifting assembly is installed inside the support frame body 1; the material receiving assembly 2 is installed at the upper end of the support frame body 1; wherein, the material receiving assembly 2 includes an adjusting frame 21, a support component, and a laterally clamping component with an adjustable opening for guiding the movement of the automotive black film and limiting the automotive black film;

[0069] The lower end of the adjusting frame 21 is fixedly installed at the upper end of the support frame body 1; the laterally clamping component is installed on the adjusting frame 21; the support component for supporting the bottom of the automotive black film is movably installed on the adjusting frame 21; the upper end surface of the adjusting frame 21 is inclined to guide the automotive black film to fall onto the support component.

[0070] The present utility model discloses an automatic film collecting device for automotive black film. A lateral clamping component and a supporting component are arranged on the adjusting frame 21. The positions of both the lateral clamping component and the supporting component can be adjusted, which can be used to clamp automotive black films of different sizes, realizing the film collecting of automotive black films of different sizes. The overall applicability is relatively wide, the use effect is good, and it has a good application prospect.

[0071] Before use, adjust the lateral clamping component and the supporting component according to the size of the die-cut automotive black film. When the automotive black film is relatively wide, adjust the opening of the lateral clamping component. When the automotive black film is relatively long, adjust the position of the supporting component, so as to realize the stable limiting of the automotive black film.

[0072] Embodiment 2:

[0073] On the basis of Embodiment 1, as Figure 1 - Figure 7 shown, the present embodiment also discloses the following structure.

[0074] The lateral clamping component includes a guiding clamping plate 22, a sliding plate 23 and a bidirectional telescopic rod 24;

[0075] The number of the guiding clamping plates 22 is two groups, and the two groups of guiding clamping plates 22 are symmetrically installed inside the adjusting frame 21; the number of the sliding plates 23 is two groups. The convex blocks at the lower ends of the guiding clamping plates 22 penetrate through the strip-shaped openings on the adjusting frame 21 and are fixedly connected with the sliding plates 23; the main body of the bidirectional telescopic rod 24 is fixedly installed on the adjusting frame 21, and the two telescopic ends of the bidirectional telescopic rod 24 are respectively fixedly connected with the two sliding plates 23.

[0076] The bidirectional telescopic rod 24 can drive the two sliding plates 23 to move towards or away from each other, thereby driving the two guiding clamping plates 22 to move, so as to change the distance between the guiding clamping plates 22, enabling the guiding clamping plates 22 to clamp automotive black films of different widths.

[0077] The guiding clamping plate 22 is composed of an inclined guiding plate and a strip-shaped plate for clamping the automotive black film. After being guided, the black film can directly move between the guiding clamping plates 22 to realize limiting, without the assistance of staff, which is relatively convenient to use.

[0078] Before use, start the bidirectional telescopic rod 24 according to the size of the automotive black film. The bidirectional telescopic rod 24 drives the guiding clamping plate 22 to move, changing the distance between the guiding clamping plates 22, so as to be applicable to the film collecting of automotive black films of different widths.

[0079] The supporting component includes a stop member 25 with an L-shaped end face and a clamping block 26;

[0080] The stop member 25 is arranged at the upper end of the adjusting frame 21; the clamping block 26 is fixedly installed inside the adjusting frame 21;

[0081] Among them, a plurality of groups of limiting tooth grooves 27 are formed on the upper end surface of the clamping block 26, and the convex strip at the lower end of the blocking member 25 passes through the opening on the adjusting frame 21 and is clamped with the limiting tooth grooves 27.

[0082] During use, the blocking member 25 can be pulled obliquely upwards to separate the blocking member 25 from the clamping block 26, and then the blocking member 25 is moved according to the length of the automotive black film, so that the blocking member 25 is inserted into the limiting tooth grooves 27.

[0083] The limiting tooth grooves 27 are arranged obliquely upwards. Therefore, when the convex strip at the lower end of the blocking member 25 is inserted into the limiting tooth grooves 27, the force in the direction of the rotating part cannot push the blocking member 25, thereby realizing the limitation of the position of the automotive black film.

[0084] Embodiment 3:

[0085] Based on Embodiment 2, as Figure 1 - Figure 7 shown, this embodiment also records the following structure.

[0086] The adjusting frame 21 includes a bottom, a rotating part and a support frame 28;

[0087] The bottom is fixedly installed on the support frame body 1; one end of the rotating part is rotationally connected to the bottom through a hinge; the support frame 28 is arranged at the end of the bottom away from the hinge and is used to support the other end of the rotating part.

[0088] The rotational setting between the bottom and the rotating part enables it to better guide the sliding of the automotive black film.

[0089] The support frame 28 includes a cross bar 29 and two groups of support rods;

[0090] The number of support rods is two groups. The support rods are fixedly installed on the bottom, and a plurality of groups of fixing hole positions are equidistantly formed on the opposite end faces of the support rods; a convex block is arranged at one end of the cross bar 29, and an adjusting block 291 is movably installed at the other end of the cross bar 29. The convex block and the adjusting block 291 are inserted into the fixing hole positions at the same height on different support rods.

[0091] The height of the cross bar 29 can be adjusted. Since the rotating part is lapped on the cross bar 29, when the height of the cross bar 29 is adjusted, the end height of the rotating part is correspondingly adjusted.

[0092] A cavity is formed inside the cross bar 29, a spring 292 is installed inside the cavity, a dial block is arranged at the end of the spring 292, one end of the dial block passes through the sliding opening on the cross bar 29, and one end of the adjusting block 291 is fixedly installed on the dial block.

[0093] A strip-shaped groove is formed on the cross bar 29, a support bar 293 is rotationally installed inside the strip-shaped groove through a pin shaft, and the lower end surface of the rotating part is attached to the upper end surface of the support bar 293.

[0094] When the rotating part overlaps the support bar 293, the inclined support bar 293 is subjected to force and its direction is deflected, so that the support bar 293 fits the rotating part, and the supporting effect is good and the stability is high.

[0095] The utility model records an automatic material collecting device for automobile black film, wherein the support frame 28 in the adjustment frame 21 can be adjusted, and the height of the rotating part can be changed by changing the height of the cross bar 29, so that the material collecting device can be suitable for different die-cutting machines, and the overall adaptability is relatively high. In addition, a rotatable support bar 293 is used to support the rotating part, and the support bar 293 is fully fitted with the lower end surface of the rotating part, so the overall stability is high, the use effect is good, and it has a good use prospect.

[0096] Before use, move the shift block on the cross bar 29 to separate the adjustment block 291 from the fixed hole, then move the cross bar 29, pull out the protrusion at the other end of the cross bar 29, move the cross bar 29 to a suitable height (the upper end of the rotating part and the height of the die-cutting machine are within the set range), insert the protrusion, release the shift block, and under the elastic force of the spring 292, the adjustment block 291 is inserted into the fixed hole, thereby realizing the adjustment of the height of the cross bar 29.

[0097] Embodiment 4:

[0098] On the basis of Example 3, Figure 1 - Figure 8 As shown, this embodiment also records the following structure.

[0099] The support frame 1 includes a base frame 11 and a support plate 12;

[0100] Guide grooves are provided at the four corners of the upper end surface of the base frame 11; the support plate 12 is fixedly connected to the bottom, and guide rods 13 are fixedly installed at the four corners of the lower end surface of the support plate 12, and the guide rods 13 are inserted into the guide grooves; wherein, there are two groups of constant force lifting components, which are symmetrically arranged on the base frame 11, and the height of the support plate 12 is adjusted as the number of black films on the car increases.

[0101] The guide groove cooperates with the guide rod 13 to make the up and down movement of the support plate 12 smoother.

[0102] The constant force lifting assembly includes a constant force spring 14, a guide frame 15 and a traction frame 16;

[0103] The constant force spring 14 is fixedly mounted on the base frame 11; the guide frame 15 is fixedly mounted on the base frame 11 near the side end surface; the traction frame 16 is fixedly mounted on the support plate 12;

[0104] One end of the constant force spring 14 is fixedly connected to the outer surface of the traction frame 16 after being guided by the guide frame 15 .

[0105] When the number of black films increases, the pressure on the constant force spring 14 becomes larger at this time. Therefore, the constant force spring 14 stretches, and at this time, the support plate 12 descends.

[0106] During use, the upper end of the rotating part and the die-cutting machine are within the set height range. When the black film is relatively light, the descending amplitude each time is insufficient. Therefore, there needs to be a certain height difference between the upper end of the rotating part and the die-cutting machine. When the upper end of the rotating part and the die-cutting machine are at the same height, at this time, manual labor is required to remove the black film. When the black film is heavier, the staff can regularly remove the black film.

[0107] The lighter the black film, the greater the height difference between the upper end of the rotating part and the outlet of the die-cutting machine, and the die-cutting machine is higher than the upper end of the rotating part.

[0108] The present utility model describes an automatic material collecting device for automotive black films, which describes a support frame body 1. The constant force lifting assembly on the support frame body 1 can change the height of the support frame body 1 in real time. When the number of black films increases, the constant force spring 14 will be stretched, so that during the material collecting process, the movement paths of the black films are the same, all slowly descending, ensuring that the cut sheets are more fitting, facilitating subsequent sorting, with good use effects and having a good application prospect.

[0109] Finally, it should be noted that: Obviously, the above embodiments are merely examples given for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
