Description

Technical Field

[0001] The utility model relates to the technical field of film production, in particular to a film counting device. Background Art

[0002] Film is a thin and uniform film-like material made of plastic material. Plastic film is usually used in packaging, protection, isolation and other fields. Common plastic film materials include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyester (PET), etc. Plastic film can be prepared by extrusion, film blowing, coating and other processes. In daily life, plastic film bags, cling film, foam film, etc. are common applications. After the film is produced, it needs to be rolled up. When rolling, in order to ensure that the same amount of film is rolled up on each roll, a counter needs to be set on the film. The sensor in the counter is driven by the roller to rotate to count the film.

[0003] When counting the film, the counter's roller contacts the film to count, but the contact area between the roller and the film is relatively small, and the film and the roller are prone to slipping, so the value counted by the counter is inaccurate. Therefore, there is a need for further optimization of the way the film counter fits the film. Utility Model Content

[0024] Specifically, the belt loop 23 is provided with anti-slip stripes to increase the friction with the contact surface.

[0025] In this implementation, please refer to Figure 1 The anti-skid stripes on the surface of the belt loop 23 can increase the friction coefficient between the belt loop 23 and the contact surface, thereby increasing the friction force between the belt loop 23 and the contact surface, thereby reducing the possibility of slipping between the belt loop 23 and the film.

[0026] Specifically, a convex strip 24 is fixed on the inner wall of the belt loop 23 , and the convex strip 24 is movably connected to the inner wall of the groove on the surface of the roller 22 .

[0027] In this implementation, please refer to Figure 2 and Figure 4The convex strip 24 is movably connected in the groove of the roller 22 to prevent the belt loop 23 from moving back and forth during rotation, making the belt loop 23 more stable during use.

[0028] Specifically, a fixing plate is provided on the upper rod 36 for quickly installing the upper rod 36 .

[0029] In this implementation, please refer to Figure 2 The fixing plate is provided with through holes for the screws to pass through, which makes installation more convenient.

[0030] Specifically, the circular pad 33 is a rubber pad, which is used to increase the friction between the circular plate 32 and the circular plate 32 .

[0031] In this implementation, please refer to Figure 2 and Figure 3 The friction coefficient between the rubber round pad 33 and the contact surface is relatively large, so the friction force generated with the contact surface is relatively large, which will be more stable during fixation, and the round pad 33 can also protect the circular plate 32 to prevent the circular plate 32 from being damaged.

[0032] Specifically, the end of the screw rod 34 is spherical, so as to increase the contact area with the finger.

[0033] In this implementation, please refer to Figure 2 and Figure 3 The spherical shape allows the fingers to have more space to grip the screw 34, which makes it more convenient to rotate the screw 34 with the fingers. Anti-slip stripes are provided on the surface of the spherical shape to increase the friction between the fingers and avoid slipping when rotating.

[0034] Specifically, the connecting rod 35 rotates within the mounting seat 31 through the circular plate 32 within a range of zero to three hundred and sixty degrees.

[0035] In this implementation, please refer to Figure 2 and Figure 3 The connecting rod 35 can rotate one circle in the mounting seat 31, so the overall scope of use is larger and the limitation of the overall installation will be smaller.

[0036] The working principle and use process of the utility model are as follows: the whole is installed through the fixing plate on the upper rod 36 of the installation component 3. After installation, the angle of the installation plate 21 is adjusted according to the angle between the belt loop 23 and the film. During the process, the round pad 33 is driven away from the round plate 32 by the screw rod 34, and then the installation plate 21 can be rotated. After the adjustment is completed, the screw rod 34 is tightened to fit the round pad 33 on the round plate 32, and then the belt loop 23 is fit on the film, and the downward force of the spring 37 in the upper rod 36 is used. The force will be transmitted to the connecting rod 35 through the limit plate 38, the connecting rod 35 will transmit the force to the mounting plate 21 through the circular plate 32 and the mounting seat 31, the mounting plate 21 will transmit the force to the belt loop 23 through the roller 22, thereby increasing the friction between the belt loop 23 and the film. After that, when the film is moving, the film will drive the belt loop 23 to rotate, the belt loop 23 will drive the roller 22 to rotate, and the roller 22 will drive the counter 1 to rotate. After the sensor inside the counter 1 rotates, the number of films can be calculated.
