Description

Technical Field

[0001] The present invention relates to the technical field of film covering treatment, and particularly to a fully covered film packaging machine with precise positioning. Background Art

[0002] Traditional automatic film covering machines require manual pulling of plastic films, and the plastic films are wound around the winding wheel after passing through the rolling wheels and traction wheels inside the film covering machine. During this process, hands need to reach into the film covering machine for auxiliary operations, resulting in low working safety. Secondly, during the film covering process, due to the lack of precise positioning, it is impossible to obtain the process and position information of the object inside the equipment, increasing the processing difficulty, making production and later maintenance inconvenient. Moreover, a large number of film covering machines on the market have a single-sided film covering structure, and multiple processes are required to achieve full film covering on the surface of the object, consuming a large amount of manpower and material resources, increasing production costs, and not meeting production needs.

Detailed implementation mode

[0022] As Figure 1 And Figure 2 In the embodiments shown, a full-coverage film packaging machine with precise positioning is proposed, which includes a film placement box 9, a transmission roller box 10, a film coating box 12, and a hot pressing box 13 arranged on the equipment platform 3. A film placement rack 41 is horizontally arranged in the film placement box 9. Baking lamps 40 are symmetrically arranged on both sides of the film placement rack 41. There is an opening at the bottom of the film placement box 9, and the opening is communicated with the opening at the top of the transmission roller box 10. Slide rails two 39 are arranged on the inner box walls on both sides of the transmission roller box 10. Electric sliders two 38 adapted to the slide rails are embedded in the slide rails two 39. A slide rail one 35 is connected between the two electric sliders two 38 through a connecting block 37. An electric slider one 34 adapted to the slide rail is embedded in the slide rail one 35. A film coating roller frame 33 is connected below the electric slider one 34. There is an opening at the bottom of the transmission roller box 10, and the opening is communicated with the opening at the top of the film coating box 12. Bottom support cylinders one 29 are arranged on the inner box walls on both sides of the film coating box 12. The end of the cylinder push rod of the bottom support cylinder one 29 is connected with a cylinder support plate one 30 adapted thereto. A sealing and cutting device 55 is arranged on the inner box wall of the film coating box 12 above the bottom support cylinder one 29. A retractable sealing and cutting knife 56 is arranged in the sealing and cutting device 55. Clamping cylinders 28 are arranged on the remaining inner box walls on the other two sides of the film coating box 12. The end of the cylinder push rod of the clamping cylinder 28 is connected with a clamping plate 49 adapted thereto. A film coating box outlet slideway 26 is arranged at the bottom opening of the film coating box 12. A laser sensor three 25 is embedded in the film coating box outlet slideway 26. A hot pressing box 13 is arranged on one side of the film coating box outlet slideway 26. Bottom support cylinders two 52 are arranged on the inner box walls on both sides of the hot pressing box 13. The end of the cylinder push rod of the bottom support cylinder two 52 is connected with a cylinder support plate two 50. A hot pressing device 44 is arranged on the remaining inner box walls on the other two sides of the hot pressing box 13. A hot pressing plate 51 is arranged on the hot pressing device 44.

[0023] Place the workpiece 18 to be packed at the feeding port 5 on the conveyor belt 17 of the feeding mechanism 4. The driving motor operates. With the cooperation of the driving wheel 16 and the driven wheel 19, the conveyor belt 17 conveys the workpiece forward and enters the film covering box 12 through the ramp chute 21. When the workpiece 18 to be packed passes through the second laser sensor, the main control device obtains the position information of the workpiece 18 to be packed and sends a feedback instruction to the first bottom support cylinder 29. After receiving the feedback instruction, the first bottom support cylinder 29 extends the cylinder support plate 30 and catches the falling workpiece 18 to be packed. The cylinder support plate 30 sends an instruction of "the cylinder support plate 30 has been received" to the main control device. The main control device issues a feedback instruction to the clamping cylinder 28. After receiving the feedback instruction, the clamping cylinder 28 extends the clamping plate to clamp the workpiece 18 to be packed. At this time, the cylinder support plate 30 retracts and leaves a gap around the workpiece 18 to be packed. The film 32 on the film placement rack 41 is pre-coated with glue, which is heated and melted into glue under the heating of the baking lamp 40 and the hot air blower 42. The film 32 is wound around the driving roller 36 and then wound around the film covering roller 31. The main control device sends instructions to the first electric slider 34 and the second electric slider 38. After receiving the instructions, the first electric slider 34 and the second electric slider 38 slide on the first slide rail 35 and the second slide rail 39 respectively according to the programmed procedures, so as to realize the film covering of the film covering roller 31 with the film 32 around the surface of the workpiece 18 to be packed for one circle. After the film covering roller 31 finishes film covering, the sealing and cutting device 55 with the sealing and cutting knife 56 performs the sealing and cutting operation. The film covering roller frame 33 resets later, and the cylinder support plate 30 retracts. The workpiece covered with film on four sides falls into the hot pressing box 13 through the film covering box outlet chute 26 at the bottom. When the workpiece passes through the third laser sensor 25, the main control device obtains the position information of the workpiece and sends a feedback instruction to the second bottom support cylinder 52. After receiving the feedback instruction, the second bottom support cylinder 52 extends the cylinder support plate 50 and catches the falling workpiece. At this time, there are still two sides of the workpiece that need to be encapsulated, and the width of the covered film is greater than the width of the workpiece, so that when the film 32 ensures that it is covered on the surface of the workpiece on four sides, there is still other part available for covering the remaining two sides of the workpiece. At this time, the first triangular hot pressing plate 53 extends to cover the corresponding part of the remaining part of the film 32 on the two sides of the workpiece, and then the second triangular hot pressing plate 54 extends to cover the last film 32 on the two sides of the workpiece, so as to realize the one-piece full coverage encapsulation of the six sides of the workpiece by one film 23. After the processing is completed, the workpiece slides out from the hot pressing box outlet chute 46 to the discharge port 14. When the workpiece passes through the fifth laser sensor 47 of the hot pressing box outlet chute 46, the position information of the workpiece is obtained by the main control device again.

The main body of the main control device is a PCB board equipped with a PLC main control chip and an affiliated control circuit.
