Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for strip products. Background Technology

[0002] As we all know, some strip-shaped products need to be cut during daily production. For example, FFC ribbon cables also need to be cut into corresponding strips in the subsequent materials during production. This is mainly done at the end of production, when the finished products are cut together. The device used for this cutting is called a cutting device.

[0003] Currently, existing cutting devices typically consist of a vertically downward-pointing blade that relies on a recognition mechanism (camera) to identify the cutting position. The cutting edge is then moved to the blade to complete the cut. However, for some strip-shaped products, relying on the recognition mechanism to identify the cutting position usually involves identifying the cutting location on the material surface. This location could be an uncut groove or a color-coded mark for easy identification. The blade then cuts along this location. However, the cutting location can be either above or below the material's surface. Existing cutting devices can only identify the cutting location on the upper surface and place the blade there, or only identify the cutting location on the lower surface and place the blade there. This is clearly insufficient for materials with cutting locations on both the upper and lower surfaces.

[0004] Therefore, it is necessary to improve the existing cutting device. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a cutting device suitable for strip products with cutting positions on both the upper and lower surfaces.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A strip product cutting device includes a main frame and a feeding mechanism, a guide seat, and a cutting mechanism mounted on the main frame. The guide seat has a guide groove, one end of which receives material discharged by the feeding mechanism. A pressure roller shaft assembly is arranged inside the guide groove. A transparent window is provided at the pressure roller shaft assembly in the guide groove. Cameras are mounted directly above and below the transparent window on the guide seat. The cutting mechanism includes a base and a movable column perpendicularly inserted into the base. A discharge port is provided at the outlet of the guide groove directly opposite the base. A first blade and a second blade are provided at the upper end of the movable column, with the cutting edges of the first blade and the second blade facing the discharge port. A square frame is provided at the lower end of the movable column. A first motor is mounted on the main frame. An eccentric wheel is provided on the rotating head of the first motor. The eccentric wheel is placed inside the square frame, and the wheel surface of the eccentric wheel contacts the square frame.

[0008] Preferably, the pressure roller assembly includes a mounting rod, a cylinder, a driven roller shaft, and a driving roller shaft. The two ends of the mounting rod are mounted on the guide seat via bearings. The push rod of the cylinder passes through the mounting rod and is hinged to two mutually symmetrical arms. The other end of each arm is connected to both ends of the driven roller shaft via bearings. The middle part of each arm is axially connected to the guide seat. The roller shaft surface of the driving roller shaft is placed at the bottom of the guide groove. The driving roller shaft is mounted on the guide seat and driven to rotate by a second motor. The driven roller shaft is located directly above the driving roller shaft.

[0009] Preferably, the transparent window comprises two transparent panels that overlap each other, with a material passage formed between the panels.

[0010] Preferably, supplementary lights are provided above and below the material guide seat, and the illumination direction of the supplementary lights is respectively facing the upper and lower surfaces of the transparent window.

[0011] Preferably, the base is provided with a tray for receiving materials at the discharge port.

[0012] Preferably, the feeding mechanism includes a self-rotating reel and at least one first guide roller shaft. Both the reel and the first guide roller shaft are mounted on the main frame. A vertical slide rail is provided between the reel and the first guide roller shaft. A slider is provided on the vertical slide rail. At least one second guide roller shaft is shaft-connected to the slider. The material discharged from the reel passes through the second guide roller shaft and the first guide roller shaft in sequence and enters the guide groove. The second guide roller shaft continuously presses down on the material.

[0013] By adopting the above solution, this utility model sets up a transparent window in the material guide trough and sets up cameras above and below the transparent window, so that the cutting position of the upper and lower end faces of the material can be detected at the same time. At the same time, a first blade that can move vertically downward and a second blade that can move vertically upward are added, so that cutting can be performed in two forms, from the top or from the bottom, thus making it well capable of cutting materials with cutting positions set on both the top and bottom.

[0022] like Figures 1 to 5 As shown, this embodiment provides a strip product cutting device, including a main frame 1 and a feeding mechanism 2, a guide seat 3, and a cutting mechanism 4 mounted on the main frame 1. The guide seat 3 is provided with a guide groove 31, one end of which receives the material discharged by the feeding mechanism 2. A pressure roller shaft assembly 5 is provided inside the guide groove 31. A transparent window 6 is provided at the pressure roller shaft assembly 5 in the guide groove 31. Cameras 7 are mounted directly above and below the transparent window 6 on the guide seat 3. The cutting mechanism 4 includes a base 41 and a cutting mechanism 42 perpendicularly inserted into the base 41. The base 41 has a movable column 42, and the base 41 has a discharge port 43 located at the outlet of the guide trough 31. The upper end of the movable column 42 is provided with a first blade 44 and a second blade 45, with the cutting edges of the first blade 44 and the second blade 45 facing the discharge port 43. The lower end of the movable column 42 is provided with a square frame 46. The main frame 1 is provided with a first motor 47, and the rotating head of the first motor 47 is provided with an eccentric wheel 48. The eccentric wheel 48 is placed inside the square frame 46, and the wheel surface of the eccentric wheel 48 is in contact with the square frame 46.

[0023] This embodiment mainly involves setting a transparent window 6 in the material guide trough 31, and setting cameras 7 on both the top and bottom of the transparent window 6, so that the cutting positions of the upper and lower ends of the material can be detected simultaneously. At the same time, a first blade 44 that can move vertically downward and a second blade 45 that can move vertically upward are added, so that cutting can be performed from the top or the bottom, thus making it well capable of cutting materials with cutting positions on both the top and bottom.

[0024] In operation, the feeding mechanism 2 guides the strip of material into the guide groove 31 of the guide seat 3. Then, the pressure roller shaft group 5 presses and guides the material, allowing it to gradually pass through the transparent window 6 and be discharged from the outlet 43. As the material passes through the transparent window 6, the cameras 7 located above and below capture images. Once one camera detects a cutting position, it can determine whether the cutting position is on the upper or lower surface of the material. When the cutting position reaches the outlet, the first motor 47 starts working, driving the eccentric wheel 48 to rotate. When the cutting position is on the upper surface, the eccentric wheel 48 rotates counterclockwise, pushing the square frame 46 downwards, thereby pulling the movable column 42 downwards. The first blade 44 and the second blade 45 move downwards simultaneously. The second blade 45 is located below, so it does not contact the material after moving downwards. After the first blade 44 moves downwards, it forms a shear at the outlet 43, thus cutting the material. Similarly, when the cutting position is on the lower surface, the eccentric wheel 48 rotates clockwise, pushing the square frame 46 upward, thereby pushing the movable column 42 upward. The first blade 44 and the second blade 45 move downward simultaneously. The first blade 44 is located at the top, so it will not contact the material after moving upward. After the second blade 45 moves downward, it will form a shear at the discharge port 43, thus cutting the material. At the same time, the main principle for cutting along the cutting position is that the material pushing speed is constant, the detection distance of the camera 7 is constant, the focal length of the camera 7 is constant, and the position of the discharge port 43 is constant. Based on the constancy of these parameters, cutting can be performed when the cutting position moves to the discharge port.

[0025] Furthermore, the gradual pushing of materials mainly relies on the pressure roller shaft assembly 5 for movement. Therefore, the pressure roller shaft assembly 5 in this embodiment specifically includes a mounting rod 51, a cylinder 52, a driven roller shaft 53, and a driving roller shaft 54. The two ends of the mounting rod 51 are mounted on the guide seat 3 through bearings. The push rod 55 of the cylinder 52 passes through the mounting rod 51 and is hinged to two mutually symmetrical arms 56. The mounting rod 51 and the push rod 55 of the cylinder 52 are designed with a clearance hole as the through-hole. The diameter of the clearance hole is larger than the diameter of the push rod 55 of the cylinder 52. The other end of the arm 56 is connected to both ends of the driven roller shaft 53 through bearings. The middle part of the arm 56 is axially connected to the guide seat 3. The roller shaft surface of the driving roller shaft 54 ​​is placed at the bottom of the guide groove 31. The driving roller shaft 54 ​​is mounted on the guide seat 3 and driven to rotate by a second motor 57. The driven roller shaft 53 is located directly above the driving roller shaft 54. The driven roller 53 and the driving roller 54 are generally made of soft rubber, which provides greater resistance and prevents slippage when pushing materials. Initially, the cylinder 52 extends, and the driven roller 53 rotates open under the drive of the arm 56. Then, the material is placed on the driving roller 54. The cylinder 52 then retracts, and the driven roller 53 presses against the material, creating a clamping effect between the driven roller 53 and the driving roller 54. As the second motor 57 rotates, it pushes the material forward. The suspended design of the cylinder 52 and the through-mounted rod 51 of the cylinder 52 are mainly to allow the cylinder 52 to adjust its angle adaptively when rotating the arm 56.

[0026] Furthermore, regarding the specific design of the transparent window 6, the transparent window 6 may include two transparent panels 61 that overlap each other, with a material passage 62 formed between the panels 61. In order to provide the lighting required for shooting, supplementary lights 63 are provided above and below the material guide seat 3 in this embodiment, and the illumination direction of the supplementary lights 63 is directly facing the upper and lower surfaces of the transparent window 6, respectively.

[0027] Furthermore, in order to receive the cut materials, the base 41 in this embodiment is provided with a tray 49 for receiving materials at the discharge port 43.

[0028] Furthermore, regarding the specific structure of the feeding mechanism 2, it can include a self-rotating reel 21 (such as a turntable with a motor) and at least one first guide roller shaft 22. Both the reel 21 and the first guide roller shaft 22 are mounted on the main frame 1. A vertical slide rail 23 is provided between the reel 21 and the first guide roller shaft 22. A slider 24 is provided on the vertical slide rail 23. At least one second guide roller shaft 25 is shaft-connected to the slider 24. The material discharged from the reel 21 passes sequentially through the second guide roller shaft 25 and the first guide roller shaft 22 into the guide groove 31. The second guide roller shaft 25 continuously presses down on the material. With this configuration, the material can be first placed on the lower end face of the second guide roller shaft 25 and then wound onto the first guide roller shaft 22. In this way, one end is pressed by the pressure roller shaft assembly 5, and the other end is on the reel 21. The material can be straightened by the gravity of the slider 24 and the second guide roller shaft 25.

[0029] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
