Description

Technical Field

[0001] This utility model relates to the technical field of die-cutting machines, specifically a die-cutting machine with a thickness detection device. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, and mobile phone pads. Die-cutting machines utilize steel blades, metal molds, and steel wire (or templates carved from steel plates) to apply pressure through an imprinting plate, cutting printed materials or cardboard into specific shapes. They are essential equipment for post-printing packaging processing.

[0003] Before die-cutting, the film thickness is tested to ensure the quality of the film. However, existing die-cutting machines can only test the film thickness and cannot remove dust from the film. Dust or impurities easily adhere to the film surface, resulting in inaccurate thickness testing. Summary of the Invention

[0004] The purpose of this invention is to provide a die-cutting machine with a thickness detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a die-cutting machine with a thickness detection device, comprising a machine body and a film, wherein the top of the machine body is provided with a detection component and a dust removal component;

[0006] The dust removal assembly includes a fixed frame, a fixed rod is slidably connected inside the fixed frame, a dust removal roller is rotatably connected to one end of the fixed rod, and a storage chamber is connected to the other end of the fixed rod through a clamping member. A scraper is installed at one end of the storage chamber, and an air suction machine is installed at the other end of the storage chamber.

[0007] The detection assembly includes a second fixed frame, a light mounted on the top of the second fixed frame, a sensor slidably connected to one end of the second fixed frame, a connecting plate mounted on one end of the sensor, a base slidably connected to the second fixed frame on one end of the connecting plate, and a rotating roller rotatably mounted on the bottom of the base.

[0008] As a further preferred embodiment of this technical solution, the bottoms of both the rotating roller and the dust removal roller are in rolling contact with the surface of the membrane, and the bottoms of both the first fixing frame and the second fixing frame are connected to the top of the machine body.

[0009] As a further preferred embodiment of this technical solution, sliders are installed on the outer sides of both the connecting plate and the sensor, and grooves adapted to the size of the sliders are opened on the inner sides of both the first and second fixing frames. The sliders and the grooves are elastically connected by a limiting spring.

[0010] As a further preferred embodiment of this technical solution, one end of the scraper is inclined upward and slidably connected to the surface of the dust removal roller.

[0011] As a further preferred embodiment of this technical solution, a through hole is provided at the top of the storage compartment near the scraper, and a connection hole for communicating with the suction machine is provided at the end of the storage compartment away from the scraper.

[0012] As a further preferred embodiment of this technical solution, the clamping component includes a connecting rod, a positioning block, a second limiting spring, and a handle. A sliding hole is provided at the other end of the fixing rod, and a connecting rod is inserted into the sliding hole. A sliding groove communicating with the sliding hole is provided on the side of the fixing rod that is close to each other. A positioning block is installed on the side of the connecting rod that extends into the sliding groove. A second limiting spring is elastically connected between the positioning block and the sliding groove. Positioning grooves adapted to the size of the positioning blocks are provided on both sides of the storage compartment. A handle is installed on the other side of the connecting rod located outside the fixing rod.

[0013] This utility model provides a die-cutting machine with a thickness detection device, which has the following advantages:

[0014] This invention uses a rotating roller to bond with the membrane. When the membrane thickness varies, the roller, sensor, connecting plate, and base move. When the sensor detects that the moving distance is greater than the maximum preset value or less than the minimum preset value, an indicator light illuminates. The dust removal roller contacts the membrane surface, removing dust and impurities, thus improving the accuracy of membrane detection. The addition of a storage chamber, air suction machine, and scraper allows for the cleaning and collection of dust and impurities from the surface of the dust removal roller. Pulling the handles away from the storage chamber allows for quick disassembly and installation of the storage chamber through the coordinated use of a connecting rod, positioning block, and limit spring, facilitating operation for staff.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, a die-cutting machine with a thickness detection device includes a machine body 1 and a film 2. The top of the machine body 1 is provided with a detection component and a dust removal component, which are used to detect and remove dust from the film 2.

[0023] The dust removal assembly includes a fixed frame 3, with a fixed rod 9 slidably connected inside the fixed frame 3. One end of the fixed rod 9 is rotatably connected to a dust removal roller 10. Multiple brushes are attached to the surface of the dust removal roller 10. When the membrane 2 passes through the dust removal roller 10, dust and impurities on the surface of the membrane 2 remain on the brushes of the dust removal roller 10, thereby cleaning the dust and impurities on the surface of the membrane 2 and preventing dust and impurities from affecting the accuracy of subsequent testing. The other end of the fixed rod 9 is connected to a storage chamber 11 via a clamping device. A scraper 12 is installed at one end of the storage chamber 11. One end of the scraper 12 is inclined upward and slidably connected to the surface of the dust removal roller 10. The addition of scraper 12 is described so that when the dust removal roller 10 rotates, the dust and impurities on the brush are blocked and remain on the scraper 12, thereby cleaning the dust removal roller 10 and improving the dust removal effect of the dust removal roller 10. An air suction machine 13 is installed at the other end of the storage chamber 11. A through hole is opened at the top of the storage chamber 11 near the scraper 12, and a connection hole connected to the air suction machine 13 is provided at the end of the storage chamber 11 away from the scraper 12. The air suction machine 13 increases the air circulation inside the storage chamber 11, so that the dust and impurities on the scraper 12 can smoothly enter the storage chamber 11 through the through hole.

[0024] The detection component includes a second fixed frame 4, with a light 401 mounted on the top of the second fixed frame 4. A sensor 5 is slidably connected to one end of the second fixed frame 4. The sensor 5 is electrically connected to the light 401. When the movement distance of the sensor 5 is greater than the maximum preset value or less than the minimum preset value, the sensor 5 controls the light 401 to light up, making it convenient for staff to observe. An external processor and a display screen are electrically connected to the sensor 5. The external processor and the display screen analyze the data of the movement of the sensor 5 and generate an image, which is displayed on the display screen, making it convenient for staff to observe and adjust the maximum or minimum preset value of the movement distance. A connecting plate 6 is mounted on one end of the sensor 5. A base 7 is slidably connected to the second fixed frame 4 on one end of the connecting plate 6. A rotating roller 8 is rotatably mounted on the bottom of the base 7. The connecting plate 6 enables the sensor 5 and the base 7 and the rotating roller 8 to move synchronously.

[0025] In this embodiment, specifically: the bottom of the rotating roller 8 and the dust removal roller 10 are in rolling contact with the surface of the membrane 2. In this way, when the thickness of the membrane 2 is different, it will move after passing through the rotating roller 8 and the dust removal roller 10. The bottom of the first fixing frame 3 and the second fixing frame 4 are connected to the top of the machine body 1. The first fixing frame 3 and the second fixing frame 4 are both U-shaped, which can both assemble parts and allow the membrane 2 to pass through them.

[0026] In this embodiment, specifically: sliders 14 are installed on the outer sides of both the connecting plate 6 and the sensor 5; grooves adapted to the size of sliders 14 are opened on the inner sides of both the first fixing bracket 3 and the second fixing bracket 4; sliders 14 and grooves are elastically connected by a limiting spring 15; sliders 14 and limiting spring 15 limit the sliding distance of connecting plate 6 and sensor 5; limiting spring 15 provides a downward force to the rotating roller 8 and dust removal roller 10, so that the rotating roller 8 and dust removal roller 10 are always in contact with the membrane 2.

[0027] In this embodiment, specifically: the clamping component includes a connecting rod 16, a positioning block 17, a second limiting spring 18, and a handle 19. A sliding hole is provided at the other end of the fixing rod 9, through which the connecting rod 16 is inserted. A sliding groove communicating with the sliding hole is provided on the side of the fixing rod 9 that is close to each other. A positioning block 17 is installed on the side of the connecting rod 16 that extends into the sliding groove. A second limiting spring 18 is elastically connected between the positioning block 17 and the sliding groove. Positioning grooves adapted to the size of the positioning block 17 are provided on both sides of the storage compartment 11. A handle 19 is installed on the other side of the connecting rod 16 located outside the fixing rod 9. The second limiting spring 18 serves to limit the positioning block 17. When the second limiting spring 18 is not subjected to external force, the positioning block 17 slides out of the sliding groove. Both the positioning block 17 and the handle 19 are larger than the diameter of the sliding hole, thereby preventing the connecting rod 16 from sliding out of the sliding hole. The positioning groove increases the friction between the storage compartment 11 and the positioning block 17, improving the stability of the storage compartment 11.

[0028] Working principle: During use, the film 2 is passed through the gap between the machine body 1, the rotating roller 8, and the dust removal roller 10. The rotating roller 8 and the dust removal roller 10 are kept in contact with the surface of the film 2 by the limiting spring 15 and the slider 14. When the die-cutting machine starts, the film 2 is conveyed through the gap between the machine body 1, the rotating roller 8, and the dust removal roller 10. When the suction machine 13 is started, as the film 2 passes through the dust removal roller 10, dust and impurities on its surface adhere to the dust removal roller 10. The dust and impurities on the dust removal roller 10 are limited by the scraper 12 and fall onto the scraper 12. Affected by the slope of the scraper 12 and the suction force, they enter through the through-hole of the storage chamber 11. When the film 2 of varying thickness passes through the rotating roller 8 into the storage chamber 11, the rotating roller 8 moves under force, causing the base 7, connecting plate 6, and sensor 5 to move. When the sensor 5 detects that the moving distance is greater than the maximum preset value or less than the minimum preset value, the control light 401 lights up to remind the staff to check. When cleaning the storage chamber 11, the handle 19 is pulled to the sides away from the storage chamber 11. The handle 19 drives the connecting rod 16 and the positioning block 17 to slide. The positioning block 17 slides from the positioning groove of the storage chamber 11 into the groove of the fixing rod 9. At this time, the storage chamber 11 is no longer limited by the positioning block 17 and can be directly removed.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
