Description

Technical Field

[0001] The utility model relates to the technical field of pre-coated films, and particularly to a detection device for pre-coated film production. Background Art

[0002] A pre-coated film refers to a process in which a plastic film is pre-coated with glue and rewound, and then laminated with a paper print. For a printed matter laminated with a film, since there is an additional thin and transparent plastic film on the surface, the surface is smoother and brighter, thereby improving the gloss and fastness of the printed matter, making the picture and text colors more vivid and three-dimensional. At the same time, it also plays roles such as waterproof, anti-fouling, wear-resistant, and chemically corrosion-resistant.

[0003] The patent specification with the publication number CN211477911U discloses a ductility detection device for pre-coated films, including a base, a first adjustment base, and a second adjustment base. A guide base is welded between the inner walls of the base. One side of the bottom walls of the first adjustment base and the second adjustment base is respectively installed with a driving gear through a wheel seat. The driving gear is movably placed in the guide base, and a clamping seat is welded on the side walls of the first adjustment base and the second adjustment base. One side inside the clamping seat is movably provided with a pressing plate through an adjustment screw. Two groups of limit seats are welded on both side walls of the first adjustment base, and a fixed shaft is arranged between the limit seats on both sides. Connecting handles are installed on both side walls of the second adjustment base. Compared with the prior art, the utility model uses mechanical force instead of manual work for detection, greatly reducing the labor intensity of workers and indirectly improving the detection accuracy.

[0004] However, it is found that the above technical solution has the following problems in the implementation of related technologies: The above device is not convenient for relatively convenient fixing work of the pre-coated film during use. Since it is necessary to rotate the bolts on both sides for fixing and unlocking, it is not convenient to perform multiple tests on a pre-coated film with a large volume. At the same time, it is difficult to know the pressure value during the test. Therefore, further improvement is needed. Summary of the Utility Model

[0005] The utility model provides a detection device for pre-coated film production, which solves the problem in related technologies that it is not convenient to quickly detect a pre-coated film when the volume is large.

[0006] The technical solution of the utility model is as follows:

[0007] A detection device for pre-coated film production, comprising a bottom plate, inside which a housing is fixedly connected. A through groove is provided inside the housing. A fixing assembly is fixedly connected inside the housing. A cross plate is fixedly connected to one side of the fixing assembly. Fixing plates are fixedly connected to both sides inside the housing. Sliding columns are slidably connected inside both fixing plates. Sliding rods are fixedly connected to the bottoms of both sliding columns. Magnetic attraction plates are fixedly connected to the bottoms of both sliding rods. Pull rods are fixedly connected to the tops of both sliding columns. A magnetic attraction strip is fixedly connected to the bottom of the cross plate. The magnetic setting between the magnetic attraction plate and the magnetic attraction strip is of opposite poles;

[0008] A fixing shell is fixedly connected to the top of the bottom plate. A motor is fixedly connected to one side of the outer part of the fixing shell. A rotating rod is fixedly connected to the motor through an output shaft. A rotating roller is fixedly connected to the outer part of the rotating rod. Connecting shells are fixedly connected to both sides of the outer part of the rotating roller.

[0009] Preferably, springs are fixedly connected inside both connecting shells. Sliding plates are fixedly connected to the tops of both springs.

[0010] Preferably, the outer surface of the sliding plate is in contact with the inside of the connecting shell. The rotating rod passes through the inside of the fixing shell and is connected to the fixing shell through a bearing.

[0011] Preferably, the sliding plate is U-shaped. A clamping plate is fixedly connected to the bottom of the sliding plate.

[0012] Preferably, the inside of the clamping plate is in fitting contact with one side of the outer part of the rotating roller. The magnetic attraction plate is in contact with the cross plate.

[0013] Preferably, auxiliary plates are fixedly connected to both sides of the outer part of the clamping plate. Both auxiliary plates are in fitting contact with one side of the outer part of the rotating roller.

[0016] The working principle and beneficial effects of the present utility model are:

[0017] 1. In the present utility model, when the sliding plate is lifted upward, during the lifting process, the sliding plate will synchronously drive the spring to stretch, and then the clamping plate will leave the outer surface of the rotating roller. At this time, the pre-coated film is laid on the outside of the rotating roller again, and then the staff releases the sliding plate. Since the spring no longer receives an upward force at this time, the spring will quickly compress and drive the sliding plate to move downward. During the movement of the sliding plate, the clamping plate will be driven to move downward synchronously. During the movement of the clamping plate, the pre-coated film will be pressed and adhered tightly to the rotating roller, thereby achieving the fixation of the pre-coated film and solving the problem of inconvenient rapid detection of the pre-coated film in the case of a large volume.

[0018] 2. In the present utility model, during the rotation of the rotating roller, the clamped pre-coated film will be driven to rotate synchronously. During the rotation of the pre-coated film, it will gradually come into contact with the pressure sensor and apply pressure to the pressure sensor. At this time, the pressure sensor will transmit the pressure sensing value electrically to the inside of the display and display it on its surface, thereby facilitating the staff to read the value and timely know whether the toughness is qualified, preventing the pre-coated film from being torn and raw materials being wasted due to the continuous rotation of the rotating roller under unknown circumstances.

SPECIFIC EMBODIMENTS

[0025] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0026] Embodiment 1

[0027] As Figures 1 to 4 shown, this embodiment proposes a detection device for pre-coated film production, including a bottom plate 1. Inside the bottom plate 1, a housing 2 is fixedly connected. A through groove is provided inside the housing 2. A fixing assembly 3 is fixedly connected inside the housing 2. One side of the fixing assembly 3 is fixedly connected to a cross plate 4. On both sides inside the housing 2, fixing plates 5 are fixedly connected. Inside both fixing plates 5, sliding columns 6 are slidably connected. At the bottom of both sliding columns 6, sliding rods 7 are fixedly connected. At the bottom of both sliding rods 7, a magnetic attraction plate 8 is fixedly connected. At the top of both sliding columns 6, a pull rod 9 is fixedly connected. At the bottom of the cross plate 4, a magnetic attraction strip 10 is fixedly connected. The magnetic settings between the magnetic attraction plate 8 and the magnetic attraction strip 10 are opposite poles;

[0028] On the top of the bottom plate 1, a fixing shell 11 is fixedly connected. On one side of the outside of the fixing shell 11, a motor 12 is fixedly connected. The motor 12 is fixedly connected to a rotating rod 13 through an output shaft. On the outside of the rotating rod 13, a rotating roller 14 is fixedly connected. On both sides of the outside of the rotating roller 14, connecting shells 15 are fixedly connected.

[0029] In this embodiment, springs 16 are fixedly connected inside both connecting shells 15. At the top of both springs 16, sliding plates 17 are fixedly connected, which can facilitate the fixed connection of the springs 16 and the sliding plates 17.

[0030] In this embodiment, the outer surface of the sliding plate 17 is in contact with the inside of the connecting shell 15. The rotating rod 13 passes through the inside of the fixing shell 11 and is connected to the fixing shell 11 through a bearing, which can facilitate the support and rotation of the rotating rod 13.

[0031] In this embodiment, the sliding plate 17 is shaped like a U shape. At the bottom of the sliding plate 17, a clamping plate 18 is fixedly connected, which can facilitate the fixation of the clamping plate 18.

[0032] In this embodiment, the inside of the clamping plate 18 is in close contact with one side of the outside of the rotating roller 14. The magnetic attraction plate 8 is in contact with the cross plate 4, which can facilitate the contact between the magnetic attraction plate 8 and the cross plate 4.

[0033] In use, when the work of toughness detection of the pre-coated film is required, first, the staff needs to pass the pre-coated film through the through groove inside the housing 2, and then lift the pull rod 9 upward. During the lifting process of the pull rod 9, the sliding column 6 and the sliding rod 7 will be driven to move upward synchronously. During the upward movement of the sliding rod 7, the magnetic attraction plate 8 will be driven to move upward synchronously and separate from the magnetic attraction strip 10. At this time, the bottom of the magnetic attraction plate 8 does not contact the top of the cross plate 4. Then, the staff passes the pre-coated film through the space between the magnetic attraction plate 8 and the cross plate 4. After that, the staff lifts the sliding plate 17 upward. During the lifting process of the sliding plate 17, the spring 16 will be stretched synchronously. Then, the clamping plate 18 will leave the outer surface of the rotating roller 14. At this time, the pre-coated film is laid on the outside of the rotating roller 14 again. Then, the staff releases the sliding plate 17. Since the spring 16 will no longer be subjected to an upward force at this time, the spring 16 will quickly compress and drive the sliding plate 17 to move downward. During the movement of the sliding plate 17, the clamping plate 18 will be driven to move downward synchronously. During the movement of the clamping plate 18, the pre-coated film will be pressed and adhered tightly to the rotating roller 14, so as to fix the pre-coated film. After that, after the staff adjusts the distance between the clamping plate 18 and the magnetic attraction plate 8, the pull rod 9 can be released. At this time, the magnetic attraction plate 8 will be magnetically attracted to the magnetic attraction strip 10, that is, the pre-coated film will be clamped and limited by the magnetic attraction plate 8 and the cross plate 4, so as to facilitate the detection work.

[0034] Embodiment 2

[0035] As Figure 1 、 Figure 3 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that both sides of the outside of the clamping plate 18 are fixedly connected with auxiliary plates 19, and both auxiliary plates 19 are in close contact with one side of the outside of the rotating roller 14, which can facilitate the connection and fixation of the auxiliary plates 19.

[0036] In this embodiment, a plurality of pressure sensors 20 are embedded in the rotating roller 14, and the plurality of pressure sensors 20 are arranged linearly, which can facilitate the fixed connection of the pressure sensors 20.

[0037] In this embodiment, one side of the top of the fixed shell 11 is fixedly connected with a display 21, and the display 21 is electrically connected to the pressure sensors 20, which can facilitate the connection and accurate display of the display 21.

[0038] During the above working process, the movement of the pallet 18 will synchronously drive the auxiliary plate 19 to move. After the auxiliary plate 19 drives the pre-coated film laminating rotating roller 14, the contact area will be increased. When it is necessary to perform inspection work, first, the staff needs to turn on the motor 12. After the motor 12 is turned on, it will synchronously drive the rotating rod 13 to rotate. During the rotation of the rotating rod 13, it will synchronously drive the rotating roller 14 to rotate. During the rotation of the rotating roller 14, it will synchronously drive the clamped pre-coated film to rotate. During the rotation of the pre-coated film, it will gradually contact the pressure sensor 20 and apply pressure to the pressure sensor 20. At this time, the pressure sensor 20 will transmit the pressure sensing value electrically to the inside of the display 21 and display it on its surface, so that it is convenient for the staff to read the value and timely know whether the toughness is qualified, preventing the situation that the pre-coated film is torn and raw materials are wasted due to the continuous rotation of the rotating roller 14 under unknown circumstances.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
