Abstract
Description
Technical Field
[0001] The utility model belongs to the field of film sticking equipment, and in particular relates to a film sticking recovery device. Background Art
[0002] Film paper (release paper) is usually provided on the back of the film to isolate the sticky layer. When using the film, the film paper needs to be torn off. In many construction occasions, it is necessary to continuously peel off long strips of film paper. If these film papers are placed randomly, they will take up space. In this case, a recycling device is usually used to recycle these film papers. The recycling device generally uses a motor to drive a self-rotating shaft to reel the film paper. However, there are some problems with the current recycling device. For example, the speed of the motor used for driving is usually constant, and the output speed of the film paper may change due to the progress of the work. Once the motor speed is greater than the output speed of the film paper, the film paper will be torn off, affecting the reeling process. Utility Model Content

DETAILED DESCRIPTION
[0015] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0016] Example
[0017] like Figure 1-Figure 2 , Figure 4 As shown, this embodiment includes a rectangular bottom plate 1, a box body 2 arranged on the rear of the bottom plate 1, and a control panel for controlling the operation of the recycling device is arranged in the box body 2. A cover plate 3 is arranged on the side of the box body 2 facing the front of the bottom plate 1, and a winding core 4 is arranged on the cover plate 3, which penetrates the cover plate 3 and can rotate under the drive of a motor. The motor is located in the box body 2 and is transmission-connected to one end of the winding core 4. A baffle 5 that can rotate with the winding core 4 as the axis is sleeved on the other end of the winding core 4. The part of the winding core 4 located outside the box body 2 is used to place the paper roll for winding the recycled film paper. In this embodiment, the size of the winding core 4 corresponds to the smallest size of the paper roll. A power interface 6, a power switch 7, a speed knob 8 and a steering switch 9 connected to the control panel signal are provided on the side of the box body 2 away from the cover plate 3. The power interface 6 is used to connect an external power supply to provide the recovery device with the energy required for its operation. The power switch 7 is used to send instructions to the control panel to control the start and stop of the recovery device. The speed knob 8 and the steering switch 9 are both used to control the motor to change the rotation action of the winding core 4, including the speed and direction.
[0018] like Figure 1-Figure 3As shown, the cover plate 3 is also provided with a rotating shaft 10 that passes through the cover plate 3 and is located below the winding core 4. The end of the rotating shaft 10 located inside the box body 2 is provided with a sensor baffle 11 that can rotate with the rotating shaft 10. The other end of the rotating shaft 10 located outside the box body 2 is connected to a pressure rod 12. The pressure rod 12 is located in the front part of the bottom plate 1, is relatively parallel to the winding core 4, and has a certain gap between it and the bottom plate 1 under normal conditions. The gap is the space for the film paper to pass through. The pressure rod 12 is provided with a locking block 13 that abuts on the bottom plate 1 at one end away from the box body 2, and the other end of the pressure rod 12 is connected to the rotating shaft through a transmission rod 14. The box body 2 is also provided with a photoelectric switch 15 connected to the control board signal and located in the rotation path of the sensor baffle 11. Specifically, the paper roll for rolling up the film paper is sleeved on the winding core 4, one end of the film paper is fixed on the paper roll, and then the motor is started to rotate the paper roll to roll up the film paper. When the rotation speed of the paper roll is faster than the speed at which the film paper comes out of the printer, the film paper will change from a loose state to a tight state. During this change, the force brought by the tight film paper will lift the pressure rod 12 pressed thereon, and the lifting action of the pressure rod 12 will The sensor baffle 11 is driven to rotate by the rotating shaft 10. When the sensor baffle 11 rotates until it enters the photoelectric switch 15, the photoelectric switch 15 outputs a signal to the control board, and the control board controls the motor to stop rotating. As the speed of the paper roll decreases until it is lower than the speed at which the film paper comes out of the printer, the pressure rod 12 returns to its initial position, the sensor baffle 11 escapes from the photoelectric switch 15, and the motor restarts working under the control of the control board. The pressure rod 12 repeats between the lifting action and the falling action until the film paper is recovered. In addition, the aforementioned locking block 13 is used to prevent the film paper from moving outward from one side of the pressure rod 12.
[0019] like Figure 1 , Figure 4 As shown, a slide groove 16 is provided on the peripheral side of the core 4, and a size expansion component 17 that can cooperate with the core 4 is connected to the outer shell of the core 4. The size expansion component 17 can be clamped with the core 4 through the slide groove 16. The size expansion component 17 can be sleeved on the core 4 to expand the size of the paper roll that the core 4 can carry.
[0020] like Figure 1-Figure 4 As shown, a handle 18 is fixed on the top of the box body 2, and the recovery device can be lifted by the handle 18, that is, the handle 18 improves the portability of the recovery device.
[0021] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
