Description

Technical Field

[0001] The utility model relates to the technical field of limiting mechanisms, in particular to an automatic limiting mechanism for cutting film bag raw materials. Background Art

[0002] The raw materials of film bags, such as roll film, film bags for packaging of precision instruments in solar energy, medicines, food packaging, etc. are usually processed in dust-free workshops. During the process of processing the film into film bags, it is necessary to use cutting equipment to cut it, and before cutting, it is necessary to use a limit mechanism to position the film so that the film cutting can be accurate.

[0003] In practice, the roll film is positioned on the unwinding device. When cutting the film of appropriate length, the film needs to be pulled out from the roll film, and then the film is positioned, and then the film can be cut. Finally, the multiple cut films are rolled up using the winding device. The existing limiting mechanism can generally only position the film, which is not convenient for pulling the film and requires manual operation by the staff, which is more troublesome. Moreover, the cut film needs to be sorted, which increases the workload of the staff. Therefore, an automatic limiting mechanism for cutting film bag raw materials is urgently needed to solve the above problems. Utility Model Content

[0020] See also Figure 1-4 , the embodiments of the utility model are further described;

[0021] An automatic limit mechanism for cutting film bag raw materials, comprising a base plate 1, an electric clamping component, a distance measuring component, a conveying mechanism and a control module;

[0022] The electric clamping assembly is located above the substrate 1 and is used to automatically clamp the film; two distance measuring assemblies are provided and are respectively installed at the two clamping ends of the electric clamping assembly; the conveying mechanism is fixed on the substrate 1, and the electric clamping assembly is installed on the conveying mechanism to transport the electric clamping assembly; the control module is fixed on the substrate 1, and the electric clamping assembly, the distance measuring assembly and the conveying mechanism are all electrically connected to the control module;

[0023] In practice, the roll film is positioned on the unwinding device. When cutting the film of appropriate length, the film needs to be pulled out from the roll film, and then the film is positioned, and then the film can be cut, and the multiple cut films after cutting are rolled up by the winding device. The existing limiting mechanism can generally only position the film, which is not convenient for pulling the film, and requires manual operation by the staff, which is more troublesome. Moreover, the cut film needs to be sorted, which increases the workload of the staff. In order to solve the above problems, the specific operation of the limiting mechanism is as follows:

[0024] The control module is preferably a PLC controller 2, and can also be a control module such as a control panel, a computer, etc., through which the working interval time of the electric clamping component and the conveying mechanism and the distance value of the distance measuring component (that is, the zero distance value from the clamping end of the electric clamping component to the film, so that the electric clamping component clamps the film) can be preset;

[0025] The electric clamping assembly is started by clicking on the control module. When the electric clamping assembly is working, it will drive the two clamping ends on it to move away from each other. After 4 seconds, the control module will turn off the electric clamping assembly. When cutting the film in the roll film for the first time, the staff needs to pull the film to move it between the two clamping ends on the electric clamping assembly, and then click on the control module again to start the electric clamping assembly. At this time, the electric clamping assembly will drive the two clamping ends on it to move toward the film. During this process, the distance measuring assembly will measure the distance between itself and the film, and feed back the measured data to the control module. When the distance value obtained by the control module is equal to the preset value, the control module will turn off the electric clamping assembly, and the electric clamping assembly will clamp the film at this time;

[0026] Then the control module will start the conveying mechanism, and the conveying mechanism will transmit the electric clamping assembly. During this process, the electric clamping assembly will pull the film so that the film gradually approaches the winding device, and the rolled film will rotate on the unwinding device. When the conveying mechanism drives the electric clamping assembly to approach the winding device, the control module will close the conveying mechanism, and the staff can pinch the end of the film. After 3 seconds, the control module will start the electric clamping assembly to move the two clamping ends of the electric clamping assembly away from each other. Then the control module will close the electric clamping assembly so that the staff can fix the end of the film on the winding device. Then the staff will click on the control module again to start the conveying mechanism to send the electric clamping assembly back to its original position. When it returns to its original position, the control module will close the conveying mechanism and start the electric clamping assembly to clamp the film. The clamping operation will not be repeated here. Then the film can be cut. At this time, the cut film is still in the electric clamping assembly. The cut film is wound by starting the conveying mechanism and the winding device. Through the above operation, there is no need for the staff to personally pull the film and arrange the film when it is wound; according to the above operation, the next round of film traction and positioning operations can be performed.

[0027] The electric clamping assembly includes a bracket 5, an electric cylinder 6 and a clamping plate 7. The bracket 5 is installed on the conveying mechanism. Two electric cylinders 6 are provided and symmetrically distributed and fixed on the bracket 5. The electric cylinders 6 are electrically connected to the control module. Two clamping plates 7 are provided and are respectively fixed to the output ends of the two electric cylinders 6. The clamping ends of the two clamping plates 7 are both provided with mounting grooves 9. The two distance measuring assemblies are respectively installed in the two mounting grooves 9.

[0028] The bracket 5 is used to support the electric cylinder 6 and the clamping plate 7. When the control module starts one or two electric cylinders 6 (depending on the actual situation), the electric cylinder 6 will drive the clamping plate 7 thereon to move when working, so that the two clamping plates 7 can be moved closer to or farther away from each other, thereby completing the clamping and releasing operations of the film. The conveying mechanism can drive the bracket 5 when working, thereby pulling the clamped film.

[0029] The conveying mechanism includes two parallel electric guide rails 3, both of which are fixed on the base plate 1, and both of which are electrically connected to the control module. Both of the electric guide rails 3 are transmission-connected with sliders 4, and both of which are fixed on the bottom of the bracket 5.

[0030] When the control module starts the two electric guide rails 3, the electric guide rails 3 will drive the sliders 4 thereon to slide, and the two sliders 4 will drive the brackets 5 to move, so as to complete the film pulling operation.

[0031] The distance measuring component includes a distance measuring sensor 10, and the distance measuring sensor 10 is electrically connected to the control module;

[0032] The distance measuring sensor 10 is used to measure the distance from itself to the film.

[0033] The clamping ends of the clamping plates 7 are fixed with soft rubber pads 8, which are staggered with the mounting grooves 9. The provision of the soft rubber pads 8 makes the clamping ends of the clamping plates 7 softer, thus avoiding film clamping.
