[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] See also Figures 1 to 3 The embodiment of the utility model provides a mechanically adjustable pneumatic pressure top wrapping machine, which realizes the expansion of the total downward pressure stroke of the pressure plate by coordinating the stroke of the cylinder with an adjustable height. The wrapping machine includes a base 1, a turntable 2, a film frame 3, a cylinder 4 and a pressure plate 5.

[0022] The base 1 carries the turntable 2, and the film frame 3 has a rolled film and a film discharge motor. The film is continuously discharged under the drive of the film discharge motor. The film frame 3 is a prior art. For details, please refer to the rocker machine series or model YL-RF series fully automatic rocker winding and laminating machine produced by Jinan Lanpaike Intelligent Equipment Co., Ltd. The cylinder 4 is used to lift or lower the pressure plate 5 so that the pressure plate 5 presses down to fix the goods.

[0023] The turntable 2 is rotatably connected to the base 1 , the film frame 3 is slidably connected to the first linear guide 6 , the cylinder 4 is slidably connected to the second linear guide 8 through a set of sliding brackets 7 , and the first linear guide 6 and the second linear guide 8 are vertically connected to the base 1 .

[0024] The goods are placed on the turntable 2, which drives the goods to rotate axially and cooperates with the film frame 3 to wrap the goods with film. The embodiment of the utility model also includes a turntable drive motor, and the output shaft of the turntable drive motor is connected to the rotating shaft of the turntable 2 through a chain to provide power for the rotation of the turntable 2.

[0025] The film frame 3 vertically rises or falls along the first linear guide rail 6, and the film is discharged along with the rotation of the goods, so that the side of the goods is completely wrapped with the film. The first linear guide rail 6 can be an electric guide rail driven by a servo motor.

[0026] Two sliding brackets 7 form a group, which are respectively connected to the bottom and top movable ends of the cylinder 4. The sliding brackets 7 are slidably connected to the second linear guide rail 8 through the guide rail slider, and the top sliding bracket 7 slides vertically along the second linear guide rail 8 as the cylinder 4 expands and contracts. Generally, combined with the ability of the cylinder 4 to press down and fix the goods, the length of the second linear guide rail 8 is greater than three times the length of the cylinder 4, so that the stroke of the cylinder 4 is extended to three times the original.

[0027] The top and bottom of the sliding bracket 7 are respectively connected with a first brake pin 9 and a second brake pin 10 that extend and retract toward the second linear guide rail 8 . The second linear guide rail 8 is provided with a plurality of fixing holes along the length direction.

[0028] The plurality of fixing holes are arranged equidistantly, and the distance between them can be set according to the stroke extension requirement of the cylinder 4. In the embodiment of the utility model, the distance between two adjacent fixing holes is 80 mm.

[0029] After the sliding bracket 7 slides along the second linear guide rail 8, the first brake pin 9 and the second brake pin 10 are used to cooperate and brake to achieve the limited position fixation of the sliding bracket 7. Specifically, in the initial state, Figure 1As shown, the first brake pin 9 extends into the fixed hole on the second linear guide 8, and the second brake pin 10 retracts, so that the bottom sliding bracket 7 is limited and fixed, and the top sliding bracket 7 can be extended and retracted with the movable end of the cylinder 4 to raise or lower the height of the pressure plate 5. When it is necessary to extend the stroke of the cylinder 4, when the cylinder 4 is extended, the second brake pin 10 extends into the fixed hole on the second linear guide 8, the first brake pin 9 retracts, the bottom sliding bracket 7 is released from the limit, and the cylinder 4 is controlled to shorten. Since the movable end of the cylinder 4 is limited and fixed with the top sliding bracket 7, the bottom of the cylinder 4 will slide upward with the bottom sliding bracket 7. After sliding to the required position, the first brake pin 9 extends into another fixed hole on the second linear guide 8, the second brake pin 10 retracts, and the top sliding bracket 7 and the movable end of the cylinder 4 resume the slidable state. As the cylinder 4 extends again, the stroke of the cylinder 4 is extended, as shown in FIG. Figure 3 shown.

[0030] The top of the sliding bracket 7 is connected to the pressure plate 5 through a connecting arm 11. The connecting arm 11 is an L-shaped bending structure. One end of the L-shaped bending structure is fixedly connected to the top of the sliding bracket 7, and the other end is rotatably connected to the pressure plate 5 to facilitate the torque transmission between the movable end of the cylinder 4 and the pressure plate.

[0031] In addition, in the embodiment of the utility model, a connecting plate 12 is connected to the top of the pressure plate 5, and the ends of the connecting plate 12 and the connecting arm 11 are provided with corresponding groups of long holes 13, and bolts are detachably connected in the groups of long holes 13. By adjusting the relative positions of the connecting plate 12 and the long holes 13 on the connecting arm 11, the lateral distance between the pressure plate 5 and the second linear guide rail 8 can be achieved, that is, the lateral position of the pressure plate 5 can be adjusted, and the pressure plate 5 can be fixed with bolts, so that the pressure plate 5 can press down and fix goods of different shapes.

[0032] In summary, when the mechanically adjustable pneumatic pressure-top wrapping machine provided by the embodiment of the utility model is in use, the pressure plate 5 is first lifted to a height higher than the goods to be wrapped by utilizing the cooperation relationship between the cylinder 4, the first brake pin 9, the second brake pin 10 and the second linear guide rail 8, and then the goods are placed on the turntable 2 by utilizing the conveyor, so that the axis of the goods coincides with the axis of the turntable 2, the cylinder 4 is retracted to press down on the top of the goods to fix it, and the film head is attached to the side of the goods, the film frame 3 and the turntable drive motor are started, and the film frame 3 is out of the film while the goods rotate with the turntable 2 to wrap the film, and at the same time, the film frame 3 moves along the first linear guide rail 6 to achieve film wrapping on the upper and lower parts of the goods.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
