During operation, before the mattress or sponge pad enters from the feeding end of the conveying mechanism, the controller controls the second lifting cylinder 432 to operate, and the lifting bracket 431 and the pneumatic finger 433 thereon move downward. At the same time, the pneumatic finger 433 operates to open the clamping claw. When the pneumatic finger 433 moves to the groove 449, the pneumatic finger 433 operates to close the clamping claw, and then clamps the packaging film. Then the second lifting cylinder 432 operates, and the lifting bracket 431 and the pneumatic finger 433 thereon move upward. The pneumatic finger 433 clamps the packaging film and pulls the packaging film up. The packaging film enters the wrapping space 3 driven by the mattress or sponge pad, and then the pneumatic fingers 433 operate to open the clamps and release the packaging film. The packaging film is then attached to the mattress or sponge pad and is used for subsequent wrapping operations.

[0096] In the existing wrapping machine, the packaging film is freely drooped from the top of the wrapping space into the wrapping space. This method often cannot use thin and sticky packaging films. In the process of releasing the packaging film, the existing wrapping machine is easily affected by the external environment and cannot well control the movement direction of the packaging film. At the same time, the sticky packaging film is very easy to stick to the roller and cannot be released smoothly. However, the packaging film release mechanism of the present invention can realize the wrapping operation of the mattress or sponge pad using a thinner packaging film, which can save packaging film materials; at the same time, a sticky packaging film can also be used to wrap the mattress or sponge pad tightly and not easy to expand.

[0097] More specifically, the packaging film welding mechanism includes a welding cylinder 421 and a welding head 422 connected to the piston end of the welding cylinder 421. The welding cylinder 421 is fixedly arranged on the transverse bracket 521. The movement of the welding cylinder 421 can drive the welding head 422 to enter the wrapping space 3 to weld the packaging film.

[0098] The working principle and working process of the adjustable wrapping machine of the present invention are briefly described as follows:

[0099] The cavity of the wrapping space 3 is initially in a closed state, that is, the upper wrapping assembly 310 drops to the lowest point, and the volume of the wrapping space 3 is at the minimum. Before the compressed mattress or sponge pad enters from the feeding end of the conveying mechanism, the packaging film release mechanism operates to pull up the packaging film and attach it to the mattress or sponge pad for conveying together.

[0100] The third belt conveyor device presses down to contact the mattress or sponge pad, and under the joint action of the third belt conveyor belt 622 and the first belt conveyor belt 214, the mattress or sponge pad is conveyed into the winding space 3, and the mattress or sponge pad is rolled up along the turning drive roller 323, and the mattress or sponge pad is pressed. Figure 2 The packaging is wrapped in a clockwise direction as shown, and at the same time, the attached packaging film is wrapped in the wrapping space 3 together.

[0101] During the wrapping process, as the diameter of the wrapping increases, the first lifting cylinder 512 pushes the upper lifting platform 511 to slowly rise, and the transverse drive motor 525 operates to drive the transverse support 521 to slowly move toward the feeding end of the conveying mechanism, thereby gradually expanding the diameter of the wrapping space 3, thereby expanding the wrapping space 3 to a specified diameter range, and the diameter of the long cylindrical roll of the mattress or sponge pad also gradually expands along with the wrapping space 3.

[0102] When the lifting platform 511 moves upward and the transverse support 521 moves, the downward pressure cylinder 612 pushes the third belt roller 621 and the third belt conveyor 622 to squeeze the mattress or sponge pad, and continue to convey the mattress or sponge pad into the winding space 3 until the mattress or sponge pad is completely in the winding space 3 and is wrapped with the packaging film.

[0103] Then, the welding cylinder 421 pushes the welding head 422 to weld the packaging film to roll the mattress or sponge pad into a roll to prevent it from loosening and separating after rolling. After the welding and sealing is completed, the flip cylinder 322 is folded, driving the flip bracket 321 to rotate outward, and the rolling space 3 forms an outlet, and the rolled mattress or sponge pad rolls out from the outlet.

[0104] Finally, the various structures of the adjustable wrapping machine of the present invention are reset to wait for the next working instruction of the controller.

[0105] Compared with the prior art, the adjustable wrapping machine of the present invention can set the diameter of the mattress or sponge pad after wrapping according to the needs, and then wrap mattresses or sponge pads of different specifications. The adjustable wrapping machine of the present invention is provided with an upper wrapping component and a lower wrapping component that can be relatively separated. The upper wrapping component is driven to move by the vertical motion component and the horizontal motion component, and the gap between the upper wrapping component and the lower wrapping component is expanded, thereby expanding the size of the wrapping space, and realizing the wrapping operation of mattresses or sponge pads of different sizes. The adjustable wrapping machine of the present invention is also provided with a packaging film release mechanism, which can automatically clamp and pull the packaging film to the feed end of the wrapping machine, and enter the wrapping machine together with the movement of the mattress or sponge pad for wrapping, without the need to manually put the packaging film on the mattress or sponge pad, which is convenient and fast, and reduces labor costs. The packaging film release mechanism of the present invention can use a thinner and sticky packaging film, which can save packaging film materials, and can also wrap the mattress or sponge pad more tightly and not easy to expand. At the same time, the packaging film releasing mechanism is arranged at the feeding end of the conveying mechanism, which is located outside the frame, so it is convenient for disassembly and maintenance, has high practicality, and also brings good economic benefits.

[0106] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
