DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-5 As shown in the figure, an automobile armrest packing machine includes a workbench 1. A fixing frame 2 is installed on the top side of the workbench 1. Rotating shafts 3 are rotatably installed through both inner sides of the fixing frame 2. A driving motor 4 is installed on one side of the fixing frame 2. One end of one of the rotating shafts 3 is connected to the output end of the driving motor 4 in a matching manner. A cam 5 is installed on the outer wall of the other rotating shaft 3. A mounting plate 6 is fixedly connected to the middle end of one side of the fixing frame 2. A sliding rod 7 is movably installed through the inside of the mounting plate 6. An arc-shaped block 8 is installed on the bottom side of the sliding rod 7. The cam 5 will contact the arc-shaped block 8 during operation. A limiting plate 9 is connected to the top side of the sliding rod 7. A tension spring 10 is fixedly connected between the limiting plate 9 and the mounting plate 6. The tension spring 10 is sleeved on the outer wall of the sliding rod 7. A top plate 11 is installed on the top side of the limiting plate 9. A fixing plate 12 is fixedly connected to one side of the top end of the fixing frame 2. A counter 13 is assembled on the bottom side of the fixing plate 12. The top plate 11 will contact the counter 13 during operation;

[0024] On one side of each of the rotating shafts 3, a telescopic rod 14 is installed. The acting end of the telescopic rod 14 is provided with a clamping plate 15. A friction plate 16 is assembled on one side of the clamping plate 15. Brackets 34 are fixedly connected to both ends of the bottom side of the workbench 1. A control panel 35 is installed on one side of one of the brackets 34. During operation, in practical applications, the packing machine cannot count the number of winding turns of the film during operation, resulting in over-winding, which will greatly increase the usage amount of the film and cause unnecessary waste. After placing the automobile armrest on the turntable 31, by controlling the telescopic rod 14 to extend, the clamping plate 15 approaches the automobile armrest, and the friction plate 16 on the clamping plate 15 contacts the automobile armrest, realizing the fixation of the automobile armrest, preventing the automobile armrest from moving during the subsequent film winding process, ensuring that the film can be evenly and tightly wound on its surface, and improving the stability and reliability of the packaging;

[0025] Before operation, preset the number of turns of film winding through the control panel 35, start the drive motor 4, and the drive motor 4 drives one of the rotating shafts 3 to rotate. Since the clamping plate 15 fixes the car armrest, the other rotating shaft 3 drives the cam 5 to rotate accordingly. When the protruding part of the cam 5 gradually approaches and contacts the arc-shaped block 8, the cam 5 starts to push the arc-shaped block 8 and the slide rod 7 upward, the tension spring 10 is stretched, and the top plate 11 moves upward accordingly. When the top plate 11 moves upward with the slide rod 7 to a certain position, the top plate 11 contacts the counter 13. Each time the top plate 11 contacts the counter 13, the counter 13 counts once until the counted number reaches the preset number of turns of film winding. At this time, the counter 13 sends a signal to the control panel 35, and the control panel 35 controls the drive motor 4 to stop working, thereby stopping the film winding, achieving the purpose of accurately controlling the number of turns of film winding, effectively avoiding waste of film, and at the same time ensuring the packaging effect of the car armrest. The specific model of the counter 13 is H7EC-N.

[0026] Please refer to Figure 1 , 2 As shown in Figures 3, 5, etc., on the other side of the top end of the fixing frame 2, an L-shaped frame 17 is installed. One end of the L-shaped frame 17 is fixedly connected with a sleeve 18. A compression spring 19 is fixedly connected inside the sleeve 18. One end of the compression spring 19 is fixedly connected with a movable rod 20. One end of the movable rod 20 slides through and extends to the outside of the sleeve 18 and is fixedly connected with a mounting frame 21. A tension roller 22 is installed between the two sides of the mounting frame 21 by means of a pin shaft. One end of the top side of the workbench 1 is provided with a support plate 23. A rotating shaft 24 is installed inside the support plate 23. A film reel 25 is assembled on the outer wall of the rotating shaft 24;

[0027] A support frame 26 is installed on the bottom side of the workbench 1. A cylinder 27 is installed inside the support frame 26. A circular plate 28 is installed at the working end of the cylinder 27. A servo motor 29 is installed on the top side of the circular plate 28. A through groove 30 is formed through the inside of the workbench 1. The output end of the servo motor 29 passes through the through groove 30 and is installed with a turntable 31. A limiting rod 32 is installed at the bottom edge of the turntable 31. An arc-shaped groove 33 is formed in the circular plate 28 and is arranged at 90 degrees. The bottom end of the limiting rod 32 is slidably installed inside the arc-shaped groove 33. During operation, in the production and processing of automotive parts, it is necessary to transport the completed automotive armrests to a designated area. In order to avoid physical damage such as collision and scratching to the automotive armrests during transportation, it is necessary to pack and box the automotive armrests. Therefore, a packing machine is required. In the initial state, the cylinder 27 is in a contracted state, and the circular plate 28, the servo motor 29 and the turntable 31 are in a lower position. When it is necessary to place the automotive armrests for packing, the cylinder 27 is started. The working end of the cylinder 27 extends, and the circular plate 28 moves upward, driving the servo motor 29 and the turntable 31 to rise together to a suitable position between the clamping plates 15, waiting for the placement of the automotive armrests. After the automotive armrests are fixed, in order to avoid affecting subsequent operations such as grinding operations, the cylinder 27 shortens, so that the turntable 31 leaves the packing operation area of the automotive armrests, avoiding affecting subsequent packing operations;

[0028] When it is necessary to fully package the automotive armrests, the servo motor 29 is started. The output end of the servo motor 29 drives the turntable 31 to rotate. Under the restriction of the arc-shaped groove 33 by the limiting rod 32, the turntable 31 can only rotate 90 degrees. The rotation of the turntable 31 drives the automotive armrests to rotate 90 degrees, thereby realizing the full packaging of the automotive armrests, avoiding packaging blind spots, and improving the packaging quality;

[0029] The film is led out through the rotating shaft 24. The film passes through the bottom arc surface of the tension roller 22 and is wound around the automotive armrest. During the winding process, under the action of the sleeve 18, the compression spring 19 and the movable rod 20, the tension roller 22 can automatically adjust its position according to the tension of the film. When the film tension is too large, the movable rod 20 moves into the sleeve 18, and the compression spring 19 is compressed, thereby reducing the tension. When the film tension is too small, the compression spring 19 extends, pushing the movable rod 20 to move outward, increasing the tension of the film, ensuring that the film will neither be too tight and damaged during the winding process nor too loose to affect the packaging effect.

[0030] Working principle: In the initial state, the cylinder 27 is in a contracted state, and the circular plate 28, the servo motor 29 and the turntable 31 are in a lower position. When it is necessary to place the automotive armrests for packing, the cylinder 27 is started. The working end of the cylinder 27 extends, and the circular plate 28 moves upward, driving the servo motor 29 and the turntable 31 to rise together to a suitable position between the clamping plates 15, waiting for the placement of the automotive armrests;

[0031] After placing the car armrest on the turntable 31, the telescopic rod 14 is controlled to extend, so that the clamping plate 15 approaches the car armrest. The friction plate 16 on the clamping plate 15 contacts the car armrest, realizing the fixation of the car armrest, preventing the car armrest from moving during the subsequent film winding process, ensuring that the film can be evenly and tightly wound on its surface, and improving the stability and reliability of packaging;

[0032] After the car armrest is fixed, in order to avoid affecting subsequent operations such as grinding operations, the air cylinder 27 shortens, causing the turntable 31 to leave the packaging operation area of the car armrest and avoiding affecting subsequent packaging operations;

[0033] Before the operation, the number of turns of film winding is preset through the control panel 35. Subsequently, the film is led out from the rotating shaft 24 and passes through the bottom arc surface of the tension roller 22 and is wound around the car armrest. The drive motor 4 is started, and the drive motor 4 drives one of the rotating shafts 3 to rotate. Since the clamping plate 15 fixes the car armrest, the other rotating shaft 3 drives the cam 5 to rotate accordingly. When the protruding part of the cam 5 gradually approaches and contacts the arc-shaped block 8, the cam 5 starts to push the arc-shaped block 8 and the slide rod 7 upward, the tension spring 10 is stretched, and the top plate 11 moves upward accordingly. When the top plate 11 moves upward with the slide rod 7 to a certain position, the top plate 11 contacts the counter 13. Every time the top plate 11 contacts the counter 13, the counter 13 counts once until the counted number reaches the preset number of turns of film winding. At this time, the counter 13 sends a signal to the control panel 35, and the control panel 35 controls the drive motor 4 to stop working, thereby stopping the film winding, achieving the purpose of accurately controlling the number of turns of film winding, effectively avoiding waste of film, and at the same time ensuring the packaging effect of the car armrest;

[0034] During the winding process, under the action of the sleeve 18, the compression spring 19 and the movable rod 20, the tension roller 22 can automatically adjust its position according to the tension of the film. When the film tension is too large, the movable rod 20 moves into the sleeve 18, and the compression spring 19 is compressed, thereby reducing the tension; when the film tension is too small, the compression spring 19 extends, pushing the movable rod 20 to move outward to increase the film tension, ensuring that the film will neither be too tight and damaged nor too loose to affect the packaging effect during the winding process;

[0035] When comprehensive packaging of the car armrest is required, the servo motor 29 is started. The output end of the servo motor 29 drives the turntable 31 to rotate. Under the limitation of the limiting rod 32 in the arc-shaped groove 33, the turntable 31 can only rotate by ninety degrees. The rotation of the turntable 31 drives the car armrest to rotate by ninety degrees, thereby realizing the comprehensive packaging of the car armrest, avoiding packaging blind spots, and improving the packaging quality.
