Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mattress packaging, in particular to a mattress rolling packaging machine. BACKGROUND

[0002] The mattress rolling packaging machine is used for rolling and packaging a mattress into a cylindrical roll for storage and transportation.

[0003] The existing mattress rolling packaging machine is suitable for a sponge or spring mattress with a certain thickness. After being pressed flat, the mattress is rolled and packaged. The diameter of the rolled and packaged mattress is about 25-50 cm. For some sponge or latex thin mattress with a thickness of less than 10 cm, the diameter of the rolled and packaged mattress is only 10-20 cm. Usually, these thin mattresses are rolled and packaged by another machine in a rolling manner. This is because when the mattress rolling packaging machine rolls and packages the mattress, it is achieved by pressing the mattress to drive the mattress to roll through multiple pressing points in the rolling packaging cavity. The size of the rolling packaging cavity determines the diameter of the rolled and packaged mattress. When the mattress rolling packaging machine for rolling and packaging thick mattresses is used to roll and package thin soft mattresses, the rolling packaging cavity cannot be adjusted too much due to the limitation of the mechanical structure. The mattress rolling packaging machine cannot fully contact the soft mattress and cannot drive the thin mattress to roll, so the existing mattress rolling packaging machine cannot be used for mattresses of various thicknesses.

[0058] First implementation method:

[0059] refer to Figures 1-3The mattress feeding direction is set as the upstream end, and the mattress output direction is set as the downstream end. This application discloses a mattress rolling machine comprising a frame 1, a conveying module 2, a movable module 3, a first switching device 4, and a power structure 5. The conveying module 2 is disposed on the frame 1 and is used to convey mattresses. The movable module 3 is located above the conveying module 2 and includes a rolling conveyor 31 and a rolling conveyor 32. The rolling conveyor 31 is located upstream of the rolling conveyor 32 and corresponds to a rolling mode, used to cooperate with the conveying module 2 to roll thin mattresses into small-diameter cylindrical wrappers. The rolling conveyor 32... Corresponding to the roll-up mode, it is used to cooperate with the conveyor module 2 to form a roll-up cavity to roll the thick pad into a large-diameter cylindrical shape; the first switching device 4 is located between the rolling conveyor 31 and the roll-up conveyor 32, and is used to switch to the passage between the rolling conveyor 31 and the conveyor module 2 to form a rolling cavity to realize the rolling mode, or to switch to connect the channel between the rolling conveyor 31 and the roll-up conveyor 32 to realize the roll-up mode; the power structure 5 is set on the frame 1 and connected to the movable module 3, and is used to adjust the distance between the movable module 3 and the conveyor module 2.

[0060] When the mattress is thin, the rolling mode is activated. The first switching device 4 switches to the channel between the rolling conveyor 31 and the conveying module 2. The first switching device 4, the rolling conveyor 31, and the conveying module 2 form a rolling chamber. The mattress is fed into the rolling chamber, and the power structure 5 adjusts the distance between the movable module 3 and the conveying module 2 to make it fit with the thin mattress, causing the thin mattress to roll into a small-diameter cylindrical package to complete the rolling of the mattress. When the mattress is thick, the wrapping mode is activated. The first switching device 4 switches to connect the channel between the rolling conveyor 31 and the wrapping conveyor 32, allowing the mattress to enter the wrapping conveyor 32 for wrapping under the conveying module 2. The power structure 5 adaptively adjusts the position of the rolling conveyor 31 or the wrapping conveyor 32 so that the rolling conveyor 31 or the wrapping conveyor 32 can fit with the mattress in the corresponding rolling mode or wrapping mode, so as to fully convey and drive the mattress to roll to complete the wrapping. By using the rolling conveyor 31, the wrapping conveyor 32, and the first switching device 4 to respectively target mattresses of different thicknesses and cylindrical wraps of different radii after wrapping, the power structure 5 further adjusts the distance between the rolling conveyor 31 and the wrapping conveyor 32 and the conveying module 2 within their corresponding size ranges to adapt to the mattress thickness. This greatly improves the reliability and applicability of the mattress wrapping machine, enabling the mattress wrapping machine of this application to be applicable to mattresses of different thicknesses simultaneously.

[0061] The rolling conveyor 31 and the wrapping conveyor 32 may be equipped with at least one belt drive device, or may include a combination of belt drive device and movable rollers, to adapt to the circumference of the cylindrical package formed by wrapping or rolling, so that the rolling or wrapping is more efficient.

[0062] As an optional implementation, in the roll-up mode, the rolling conveyor 31 and the conveying module 2 have the same conveying direction, which is used to make the rolling conveyor 31 and the conveying module 2 press the mattress together and send the mattress into the roll-up cavity for rolling; in the rolling mode, the rolling conveyor 31 and the conveying module 2 have opposite conveying directions, which is used to roll the thin mattress into a columnar wrap.

[0063] refer to Figure 1 As an optional implementation, a second switching device 6 is also included. The second switching device 6 is located at the downstream end of the conveying module 2 and is used to switch the second switching device 6 to the working position or the output position, so as to form a wrapping cavity between the conveying module 2 and the wrapping conveying device 32 respectively for wrapping; or to connect the downstream end of the conveying module 2 so that the cylindrical mattress roll is output from the downstream end of the conveying module 2.

[0064] As an optional implementation, the second switching device 6 includes a wrapping roller group 61 and a second switching drive member 62. The second switching drive member 62 is disposed on the frame 1, and the wrapping roller group 61 is disposed at the downstream end of the conveying module 2 and connected to the second switching drive member 62.

[0065] When the wrapping roller assembly 61 is in the working position, the second switching drive unit 62 drives the wrapping roller assembly 61 to form a wrapping cavity between the conveying module 2 and the wrapping conveying device 32 for wrapping.

[0066] When the wrapping roller group 61 is in the output position, the second switching drive unit 62 drives the wrapping roller group 61 to unfold and form an output channel with the conveying module 2, so as to facilitate the discharge of the cylindrical mattress roll formed after wrapping.

[0067] The second switching drive unit 62 can be a cylinder.

[0068] As an optional implementation, the wrapping roller assembly 61 includes at least one roller that drives the mattress to roll upward, such that each roller engages with the circumference of the cylindrical mattress roll formed by the mattress roll, thereby enabling the wrapping roller assembly 61 to fully act on the mattress and drive its roll.

[0069] By using the wrapping roller assembly 61 to accommodate thicker mattresses and the resulting cylindrical mattress rolls with larger radii, the adaptability of the mattress wrapping machine to mattresses of different thicknesses is improved. At the same time, by using the wrapping roller assembly 61 and the first switching device 4 to respectively correspond to cylindrical mattress rolls of different radii after wrapping or rolling, the phenomenon that may occur when wrapping a thin mattress with a cylindrical mattress roll whose wrapping radius is smaller than the radius corresponding to the wrapping roller assembly 61 is prevented from occurring, which may result in the wrapping conveyor 32 not being able to fully contact the mattress and thus failing to wrap, due to the obstruction of the bent part of the wrapping roller assembly 61.

[0070] It should be noted that the rollers of the rolling roller group 61 can be driven by a motor to rotate actively, so as to make them consistent with the conveying direction of the mattress in order to drive the mattress rolling.

[0071] refer to Figure 1 and Figure 3 As an optional implementation, the first switching device 4 includes a switching component 41 and a first switching drive component 42. The first switching drive component 42 is connected to the switching component 41. The first switching drive component 42 drives the switching component 41 to move and switch to the passage of the rolling conveyor 31 and the conveying module 2 to form a rolling cavity to realize the rolling mode, or switch to connect the channel between the rolling conveyor 31 and the package conveyor 32 to realize the package mode.

[0072] As an optional implementation, the switching element 41 is a movable roller that can rotate.

[0073] As an optional implementation, the first switching device 4 is disposed on the conveying module 2.

[0074] As attached Figure 5 As shown, the switching component 41 is a movable roller, and the movable roller of the conveying module 2 is set in the conveying module 2, and the movable roller can rotate. In the rolling mode, the first switching drive component 42 drives the switching component 41 to move and switch to the passage of the rolling conveying device 31 and the conveying module 2, forming a rolling cavity with the rolling conveying device 31 and the conveying module 2; at this time, the rolling conveying device 31 and the roll-up conveying device 32 are separated, and the mattress is conveyed to the rolling cavity under the drive of the conveying module 2. Under the sequential joint drive of the conveying module 2, the switching component 41 and the rolling conveying device 31, it is rolled. The power structure 5 controls the movement of the rolling conveying device 31 and adjusts its position in real time, so that it can fully contact the rolled mattress in the rolling cavity and realize the rolling.

[0075] As attached Figure 6As shown, the switching element 41 is located on the conveying module 2. In the roll-up mode, the first switching drive element 42 drives the switching element 41 to move flush with the conveying module 2, thus connecting the rolling conveyor 31 and the roll-up conveyor 32. The mattress moves sequentially to the roll-up conveyor 32 under the conveying of the conveying module 2 and the switching element 41, and then the roll-up conveyor 32 realizes the rolling up of the mattress.

[0076] The switching component 41 can be driven by a motor to rotate actively in the same direction as the conveying direction of the conveying module 2, thereby driving the mattress to roll and rub. The first switching drive component 42 can be a cylinder.

[0077] refer to Figure 1 As an optional implementation, it also includes a pressure roller assembly 7, which is located upstream of the rolling conveyor 31 and is used to cooperate with the conveyor module 2 to clamp and convey the mattress.

[0078] The pressure roller assembly 7 can be installed on the frame 1. In this case, the pressure roller assembly 7 includes a pressure roller 71 and a pressure roller drive 72. The pressure roller drive 72 is installed on the frame 1 and is used to drive the pressure roller 71 to move in the vertical direction to cooperate with the conveying module 2 to clamp and convey the mattress. The pressure roller 71 is installed on the pressure roller drive 72 and is located upstream of the rolling conveyor 31.

[0079] The pressure roller drive 72 drives the pressure roller 71 to move so as to fully act on the mattress. The pressure roller 71, in conjunction with the conveying module 2, presses the input mattress to position and guide it. At the same time, it limits and blocks the mattress input port upstream of the rolling conveyor 31 and the conveying module 2, so as to prevent the mattress entering the rolling chamber from being sent out upstream of the conveying module 2 under the drive of the rolling conveyor 31, which would affect the reliability of the rolling and thus make the rolling effect better.

[0080] The pressure roller 71 can be driven by a motor to rotate actively in the same direction as the mattress conveying direction, and the pressure roller drive component 72 can be a cylinder.

[0081] The pressure roller assembly 7 can also be set in the movable module 3. In this case, the pressure roller assembly 7 includes a pressure roller 71, which moves with the movable module 3 to fully act on the mattress, so as to cooperate with the conveying module 2 to clamp and convey the mattress.

The first conveying device 21 is disposed on the frame 1 and corresponds to the rolling conveying device 31. The second conveying device 22 is disposed on the frame 1 and is located at the downstream end of the first conveying device 21 and corresponds to the roll-packing conveying device 32. The first switching device 4 is located between the first conveying device 21 and the second conveying device 22.

[0083] The first switching device 4 blocks or opens the passage between the first conveying device 21 and the second conveying device 22 to achieve the switching between the rolling mode and the wrapping mode.

The secondary drive group 52 is disposed on the movable frame 53 and connected to the winding conveyor 31, and is used to drive the winding conveyor 31 in the movable module 3 to move relative to the movable frame 53 to further change the distance between the winding conveyor 31 and the conveying module 2.

[0086] The first-level drive group 51 drives the movable frame 53 to move, thereby changing the position of the movable module 3 and realizing the first-level adjustment of the position of the movable module 3 relative to the conveying module 2. The second-level drive group 52 realizes the second-level adjustment of the rolling conveyor 31 in the movable module 3 relative to the conveying module 2, thereby efficiently realizing the position adjustment of the rolling mode and the wrapping mode to adapt to the mattress, so that the rolling conveyor 31 and the wrapping conveyor 32 can fully contact the mattress and drive the mattress to complete the conveying, rolling or wrapping.

[0089] The movable frame 53 is driven by the primary drive component 512. During the movement of the movable frame 53, the horizontal guide mechanism 5111 and the longitudinal guide mechanism 5112 of the primary guide mechanism 511 guide the movement of the movable frame 53 in the transverse and longitudinal directions, respectively.

[0090] The primary drive unit 512 can be configured as a cylinder connected to the movable frame 53 and the frame 1 respectively. The movable frame 53 is moved by the extension and retraction of the cylinder. The horizontal guide mechanism 5111 and the longitudinal guide mechanism 5112 can both be rack and pinion transmission mechanisms. In this case, the primary drive unit 512 can also be a motor connected to the gear in the rack and pinion transmission mechanism. The motor drives the gear to rotate and mesh with the rack to achieve the movement of the movable frame 53 in the horizontal transverse direction of the horizontal guide mechanism 5111 or the vertical longitudinal direction of the longitudinal guide mechanism 5112.
