Description

Technical Field

[0001] The utility model relates to the technical field of metering equipment, in particular to a metering device for covering films and substrates. Background Art

[0002] When producing covering films, substrates and other items, they generally need to be cut and packaged according to the required length. In order to ensure the accuracy of cutting, a metering device is usually set on the slitting machine to control the cutting length.

[0003] Most existing meter-counting devices calculate the length by detecting the number of rotations of a rotating shaft. However, in actual use, the film, substrate, etc. may become loose and slip on the guide shaft. At this time, the length of one rotation of the rotating shaft is different from the actual length of the film transported, resulting in inaccurate meter-counting data of the device.

[0004] To this end, we propose a metering device for covering films and substrates to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a metering device for covering films and substrates to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A metering device for covering film and substrate comprises a roller and a counter, wherein a guide roller is arranged under the roller, and both ends of the guide roller are rotatably installed between frames, and both ends of the roller are rotatably installed between hangers, and the counter is fixed outside the hanger and coaxially connected to the roller, a top block is fixed on the hanger, a pressure block is connected to the top of the top block through a spring, and the outer periphery of the top block, the spring and the pressure block is covered with the same adjusting cylinder, and the adjusting cylinder is fixed to the top plate of the frame, a screw is installed on the pressure block, and the screw passes through the top of the adjusting cylinder and is threadedly connected to the adjusting cylinder, and when the screw rotates, the pressure block is controlled to squeeze the spring to adjust the pressure on the roller.

[0008] In a further embodiment, the outer edges of the top block and the pressure block are both provided with grooves, and the inner wall of the adjustment cylinder is connected with a convex rail matching the grooves.

[0009] In a further embodiment, the opposing surfaces of the top block and the pressure block are both formed with a raised frustum, and the frustum passes through the interior of the spring.

[0010] In a further embodiment, the screw rod and the pressing block are rotationally connected.

[0011] In a further embodiment, a digital display screen is also installed on the frame, and the digital display screen is electrically connected to the counter through a wire.

[0012] In a further embodiment, an anti-skid layer is connected to the outer circumferential side of the roller.

[0013] In a further embodiment, the anti-slip layer is made of silicone or rubber.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model controls the pressing block to squeeze the spring when the screw is rotated, and then squeezes the top block to adjust the pressure on the roller, so that the roller can press the film or substrate passing through the surface of the guide roller, effectively preventing the film or substrate from loosening and slipping, which is beneficial to improving the accuracy of the meter data. The elastic effect of the spring is used to make the roller dynamically pressed, and the situation that the film or substrate is squeezed and deformed due to excessive squeezing of the film or substrate is prevented, thereby ensuring the quality of the finished product.

[0024] See also Figure 1-3 A metering device for covering films and substrates comprises a roller 3 and a counter 5. A guide roller 2 is closely arranged under the roller 3, and both ends of the guide roller 2 are rotatably mounted between a frame 1. The guide roller 2 rotates relative to the frame 1. The film or substrate to be counted passes between the roller 3 and the guide roller 2. When the guide roller 2 guides the film or substrate to move and transport, the roller 3 is driven to rotate by the film or substrate. Both ends of the roller 3 are rotatably mounted between hangers 4, and the counter 5 is fixed outside the hanger 4 and coaxially connected to the roller 3, so as to calculate the number of rotations of the roller 3. Considering that there are films or substrates of different thicknesses that need to be counted in actual use, in order to ensure that the roller 3 fits tightly with films or substrates of different thicknesses without slipping, a top block 9 is fixed on the hanger 4. The top block 9 A pressure block 10 is connected to the top through a spring 8, and the outer periphery of the top block 9, the spring 8 and the pressure block 10 is covered with the same adjusting tube 7. The top block 9, the spring 8 and the pressure block 10 can slide up and down in the adjusting tube 7. The adjusting tube 7 is fixed to the top plate of the frame 1. A screw 11 is installed on the pressure block 10, and the screw 11 passes through the top of the adjusting tube 7 and is threadedly connected with the adjusting tube 7. When the screw 11 rotates, the screw 11 and the adjusting tube 7 have a threading effect, so that the screw 11 is screwed upward or downward relative to the adjusting tube 7, thereby driving the pressure block 10 to squeeze or loosen the spring 8, and the spring 8 squeezes the top block 9. The top block 9 squeezes the roller 3 through the hanger 4, thereby adjusting the extrusion pressure between the roller 3 and the guide roller 2, so that the roller 3 can always press the film or substrate to prevent it from slipping.

[0025] See also Figure 2-3In order to further reduce the possibility of the film or substrate slipping, an anti-skid layer 31 is connected to the outer circumferential side of the roller 3. The material of the anti-skid layer 31 is one of silicone or rubber. By setting the anti-skid layer 31, the static friction when contacting the film or substrate is increased, ensuring that the film or substrate can pull the roller 3 to rotate when moving, thereby reducing slipping.

[0026] See also Figure 4 In order to ensure that the roller 3 does not shift in position when adjusting the pressure, grooves 12 are provided on the outer edges of the top block 9 and the pressure block 10, and a convex rail 71 matching the groove 12 is connected to the inner wall of the adjusting cylinder 7. The sliding limit function between the convex rail 71 and the groove 12 is utilized to prevent the top block 9 and the pressure block 10 from deflecting when adjusting the pressure, and the stability is higher.

[0027] See also Figure 2-3 Furthermore, in order to improve stability, the opposing surfaces of the top block 9 and the pressure block 10 are formed with raised cones, which penetrate the interior of the spring 8 to reduce the possibility of bending and deflection of the spring 8. At the same time, a rotational connection is set between the screw rod 11 and the pressure block 10 so that the pressure block 10 will not hinder the normal rotation of the screw rod 11.

[0028] See also Figure 1 In order to observe the meter data more intuitively, a digital display screen 6 is also installed on the frame 1, and the digital display screen 6 is electrically connected to the counter 5 through a wire, so that the data can be displayed through the digital display screen 6.
