Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, and more particularly, to a sampling cutting device for plastic composite films. Background Art

[0002] A composite film refers to a film with a multi-layer structure formed by combining various plastics with paper, metal or other materials through processes such as lamination extrusion laminating and co-extrusion molding. The composite film is a material for the decorative processing of printed products, with a thin and soft texture and relatively large elasticity.

[0003] Based on the above, the inventor found the following problems: Sampling of plastic composite films is a key step in the quality control process, which ensures that the materials meet the established standards and requirements before entering the production or testing process. Currently, when sampling plastic composite films, operators cut them on the plastic composite films. However, due to manual cutting, the shape and size cannot be kept consistent. Therefore, during the subsequent inspection process, it is necessary to trim them again so that the testing equipment can inspect them.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a sampling cutting device for plastic composite films is provided, with the expectation of achieving a more practical value. Summary of the Utility Model

[0031] Embodiment 1 of a sampling and cutting device for plastic composite films of the present utility model

[0032] The present utility model provides the following technical solutions: As Figures 1 - 5As shown in the figure, a sampling and cutting device for plastic composite films includes a main body 100 and a cutting mechanism 200. The main body 100 includes a housing 1001. A fixed frame 1006 is fixedly installed at the inner top end of the housing 1001. The cutting mechanism 200 includes a mounting plate 2001 which is arranged at the inner bottom end of the housing 1001. Sliding plates 2007 are slidably installed on both sides of the mounting plate 2001. A cutting frame 2006 is fixedly installed at the bottom ends of a pair of sliding plates 2007. By arranging the mounting plate 2001 at the inner bottom end of the housing 1001, sliding plates 2007 are slidably installed on both sides of it, and the cutting frame 2006 is installed at the bottom ends of the sliding plates 2007, when the cutting frame 2006 presses down, the plastic composite film can be cut. Since the shape and size of the cutting frame 2006 are fixed, the shape and size of the cut samples are also the same. When performing later detection on them, it is not necessary to trim the shape and size of the plastic composite film again, improving the detection efficiency. A cross bar 2008 is fixedly installed at the top ends of a pair of sliding plates 2007. A sleeve 2009 is embedded at the center of the cross bar 2008. A screw 2010 is threadedly connected inside the sleeve 2009. The top end of the screw 2010 is rotatably connected to the bottom end of the fixed frame 1006. By installing the cross bar 2008 at the top ends of the sliding plates 2007, embedding the sleeve 2009 at the center of the cross bar 2008, and the screw 2010 threadedly connected inside it is rotatably connected to the bottom end of the fixed frame 1006. When the screw 2010 rotates, the slidably connected cutting frame 2006 can be driven to move up and down, thus facilitating the cutting and sampling of the plastic composite film.

[0033] Embodiment II of a sampling and cutting device for plastic composite films of the present utility model

[0034] Refer to Figures 1 - 5As shown in the figure, a servo motor 1005 is fixedly installed on the upper end face of the housing 1001. The output end of the servo motor 1005 is connected to the top end of the screw rod 2010 through a coupling. By installing the servo motor 1005, the screw rod 2010 can be driven to rotate when it works. Slide rods 2002 are slidably inserted at the four corners of the mounting plate 2001. The bottom ends of the four slide rods 2002 are fixedly installed with a top plate 2005. By slidably installing the slide rods 2002 at the four corners of the mounting plate 2001 and installing the top plate 2005 at their bottom ends, when the housing 1001 is placed on the plastic composite film to be sampled, the top plate 2005 can press the center of the plastic composite film, thus preventing the middle of the plastic composite film from bulging and affecting the cutting effect. Springs 2004 are sleeved on the bottom ends of the four slide rods 2002. The top ends of the springs 2004 are connected to the bottom end of the mounting plate 2001, and the bottom ends of the springs 2004 are connected to the upper end of the top plate 2005. By sleeving the springs 2004 on the bottom ends of the slide rods 2002 and connecting their two ends to the mounting plate 2001 and the top plate 2005 respectively, under the elastic force of the springs 2004, the top plate 2005 can tightly press the plastic composite film. And after the cutting is completed, when the user lifts the housing 1001, the top plate 2005 can eject the cut plastic composite film out of the interior of the housing 1001 under the elastic force of the springs 2004, facilitating the user to take the sample. Limit blocks 2003 are fixedly installed at the top ends of the four slide rods 2002. By installing the limit blocks 2003, the slide rods 2002 can be prevented from falling off the mounting plate 2001.

[0035] Embodiment Three of a Sampling and Cutting Device for Plastic Composite Films of the Present Utility Model

[0036] Refer to Figures 1 - 5 As shown in the figure, observation ports 1002 are opened on the outer sides of the bottom ends of the housing 1001, and tempered glass is installed inside the observation ports 1002. By opening the observation ports 1002 and installing tempered glass inside them, it is convenient for the user to view the sampling situation of the plastic composite film from outside the housing 1001. Handles 1003 are installed on both sides of the upper end of the housing 1001. Control buttons 1004 are provided on one side of the handles 1003. By installing the handles 1003, it is convenient for the user to lift the housing 1001 or cover it on the plastic composite film to be sampled. The control buttons 1004 are electrically connected to the servo motor 1005 through wires. By installing the control buttons 1004 and electrically connecting them to the servo motor 1005, it is convenient to control the forward and reverse rotation of the servo motor 1005, thereby adjusting the height of the cutting frame 2006 to cut the plastic composite film.

[0037] Specifically, the working principle of this plastic composite film sampling and cutting device is as follows: When in use, hold the handle 1003 with both hands, lift the housing 1001, and then place it on the upper end of the plastic composite film to be sampled. When the housing 1001 is lowered, the top plate 2005 contacts the plastic composite film first. After the spring 2004 is compressed, it will resist the top plate 2005, thereby pressing down on the plastic composite film. After the bottom end of the housing 1001 contacts the plastic composite film, the user starts the servo motor 1005 through the control button 1004 on the handle 1003. When it works, it drives the screw rod 2010 to rotate. The screw rod 2010 is threadedly connected to the sleeve 2009 embedded in the cross bar 2008. Both ends of the cross bar 2008 are connected to the top ends of the sliding plates 2007. A cutting frame 2006 is installed at the bottom end of the sliding plate 2007. Therefore, when the screw rod 2010 rotates, it can drive the sliding cutting frame 2006 to press down, thereby cutting the plastic composite film covered inside the housing 1001. Since the shape and size of the cutting frame 2006 are fixed, the size of the plastic composite film sample cut each time is the same. After the cutting is completed, the user presses the control button 1004 on the handle 1003 again to drive the servo motor 1005 to reverse, so that the screw rod 2010 drives the sliding cutting frame 2006 to rise. Then the user can lift the housing 1001. When the housing 1001 is lifted, the top plate 2005 quickly resets under the elastic force of the spring 2004, thereby ejecting the plastic composite film inside the cutting frame 2006, facilitating the user to collect the sample.

[0038] It should be noted that in a plastic composite film sampling and cutting device, the specific model specifications of the control button 1004 and the servo motor 1005 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0039] In a plastic composite film sampling and cutting device, the power supply and its principle of the control button 1004 and the servo motor 1005 are clear to those skilled in the art and will not be described in detail here.

[0040] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
