[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0036] like Figure 1-Figure 4 As shown, an embodiment of the present invention provides a mattress rolling machine, including an input component 1, a rolling component 2, a film cutting component 3, a welding component 4 and an output component 5.

[0037] The input assembly 1 is used to compress the mattress and feed it into the roll-packing assembly 2, and includes an upper input assembly 11 and a lower input assembly 12 arranged at a certain angle;

[0038] The roll assembly 2 includes a turntable drive mechanism 21, a turntable 22 and an electric roller assembly 23; the turntable drive mechanism 21 is used to drive the turntable 22 to rotate; the electric roller assembly 23 is arranged in a ring, and includes an electric roller connecting block 231, and an electric roller 232 is provided at the front end of the electric roller connecting block 231, and the electric roller 232 surrounds a mattress roll forming cavity 24; the end of the electric roller connecting block 231 is slidably connected to the turntable 22, and the electric roller assembly 23 can be driven by the turntable 22 to approach or move away from the center of the mattress roll forming cavity 24;

[0039] The film cutting assembly 3 is used to cut the packaging film, and the welding assembly 4 is used to weld the packaging film wrapped around the mattress after it is rolled.

[0040] The output assembly 5 is used to deliver the wrapped mattress. The wrapping machine is also provided with a packaging film conveying assembly 7, which includes a carrying roller 71 for carrying the packaging film 8.

[0041] By adopting the above scheme, the automatic rolling and packaging and sealing of the mattress can be realized, the degree of automation is high, manpower is saved, and production efficiency is improved.

[0042] The principle and specific structure of this embodiment are further described below:

[0043] like Fig.12 As shown, the mattress 1' undergoes the rolling and packaging processes in the rolling machine to form a compressed mattress 2', a rolled mattress 3' and a packaged mattress 4'.

[0044] First, the mattress is compressed and transported through the input assembly 1 of the wrapping machine. Figure 3, the upper input assembly 11 is hinged above the lower input assembly 12 and is connected to an opening and closing cylinder 13; the upper input assembly 11 and the lower input assembly 12 are both arranged on an input bracket 14, and the input bracket 14 can move forward and backward; the upper input assembly 11 and the lower input assembly 12 are both provided with a conveyor belt 15. Specifically, a feed motor 17, a screw rod 18, a feed guide rod 19 and a movable beam 10 are provided on the input fixed frame 16; one end of the screw rod 18 is connected to the movable beam 10, and the other end is connected to the feed motor 17; the feed motor 17 can drive the screw rod 18 to rotate, thereby driving the movable beam 10 away from or close to the input fixed frame 16; the movable beam 10 is provided with the input bracket 14, and the upper input assembly 11 and the lower input assembly 12 can be driven to move horizontally by driving the input bracket 14 through the movable beam 10.

[0045] When the mattress is delivered to the feeding end of the upper input assembly 11 and the lower input assembly 12, the opening and closing cylinder 13 drives the upper input assembly 11 to flip downward, and then the conveyor belts 15 on the upper input assembly 11 and the lower input assembly 12 drive the mattress to move, and the mattress is gradually compressed. When the mattress reaches the discharge end of the upper input assembly 11 and the lower input assembly 12, the upper input assembly 11 and the lower input assembly 12 move horizontally to deliver the compressed mattress into the rolling assembly 2. By providing a movable input bracket 14, the compressed mattress can be directly delivered to the entrance of the mattress rolling molding cavity 24, preventing the mattress from rebounding before rolling, which affects the compactness of the rolling.

[0046] Then, the wrapping assembly 2 starts to work and wraps the mattress. Figure 5-Figure 7 The turntable driving mechanism 21 includes a turntable motor 211, a transmission gear 212, a sliding plate 213 and a first linear guide rail 214; the sliding plate 213 is arranged on the first linear guide rail 214; a rack 215 is fixedly arranged on the sliding plate 213, and the transmission gear 212 is meshed with the rack 215; a driving block 216 is arranged on the sliding plate 213. The turntable 22 is provided with a first slot 221, a second slot 222 and a third slot 223; the driving block 216 is arranged in the first slot 221; the second slot 222 is annularly arranged on the turntable 22, and a first limit block 61 fixedly connected to the frame 6 is arranged in the second slot 222; a second limit block 233 is arranged in the third slot 223, and the second limit block 233 is connected to the end of the electric roller connecting block 231. The third slot 223 is arranged obliquely toward the center direction of the turntable 22. The frame 6 is further provided with a fourth slot hole 62 , and the electric roller connecting block 231 is arranged in the fourth slot hole 62 and can slide along the fourth slot hole 62 .

[0047] In the initial state, the electric roller assembly 23 is in a state of being away from each other, and the space of the mattress rolling and forming cavity 24 is relatively large. When the rolling and forming process begins, the turntable motor 211 drives the sliding plate 213 to move through the transmission gear 212, and the sliding plate 213 translates and drives the turntable 22 to rotate; because the electric roller connection block 231 is restricted by the fourth slot 62 and can only slide in the direction of the fourth slot 62, when the turntable 22 rotates, it will drive the electric roller assembly 23 to move toward the mattress rolling and forming cavity 24 through its third slot 223, so that the mattress rolling and forming cavity 24 shrinks to the minimum diameter. At this time, the input assembly 1 sends the mattress into the mattress rolling and forming cavity 24, and the electric roller 232 is provided with a motor inside, which can rotate actively; the feeding force of the mattress is provided by the rotation of the electric roller 232. During the rolling and forming process, the turntable motor 211 drives the sliding plate 213 to move through the transmission gear 212, and the sliding plate 213 translates and drives the turntable 22 to rotate, so that the mattress rolling and forming cavity 24 becomes larger according to the gradual increase in the diameter of the mattress. By setting the third slot 223 on the turntable 22, different positions of the third slot 223 have different distances from the rotation center of the turntable, so that all the electric roller assemblies 23 can follow the rotation of the turntable 22 and synchronously approach or move away from the rotation center, ensuring the consistency of the center of the roll, making the force uniform during the roll, and improving the roll quality. On the other hand, through the transmission design of the turntable motor 211, the transmission gear 212, the sliding plate 213 to the turntable 22, it is also possible to accurately control the overall relative displacement of the electric roller 232 when it is subjected to a large pressure, so that the mattress roll is compact but will not produce wrinkles due to over-tightening.

[0048] Combination Figure 8 When the wrapping is about to be completed, the packaging film is input into the wrapping mechanism, and after the wrapping mechanism continues to rotate the mattress for several turns, the cutter 31 of the film cutting component 3 moves to cut the packaging film at the film cutting component 3. After the packaging film is cut, the welding component 4 welds the packaging film.

[0049] Combination Fig. 9 The welding assembly 4 includes a welding drive cylinder 41, a guide rod 42, a fixed beam 43, a welding rectangular tube 44 and a heating plate 45; the fixed beam 43 is provided with a guide sleeve 46, the welding rectangular tube 44 is provided with a guide rod 42, and the guide rod 42 is sleeved in the guide sleeve 46; the heating plate 45 is arranged below the welding rectangular tube 44; the welding drive cylinder can drive the welding rectangular tube 44 to move up and down relative to the fixed beam 43. When welding is required, the welding drive cylinder 41 drives the welding rectangular tube 44 to descend, and the heating plate 45 contacts the packaging film on the surface of the mattress, and the opening position of the packaging film is welded and fixed to the corresponding position of the packaging film by high temperature, and the mattress packaging is completed. The addition of the automatic welding assembly 4 allows the mattress to be completely packaged and sealed before leaving the wrapping assembly 2, and can also prevent the mattress from loosening again after leaving the wrapping machine.

[0050] Preferably, in order to ensure that the welding rectangular tube 44 can be lifted and lowered in parallel, the welding assembly 4 also includes a synchronization mechanism, which includes more than two groups of parallelly arranged synchronization racks 47 and synchronization wheels 48, and the synchronization wheels 48 are connected by a synchronization rod 49; the synchronization rack 47 is connected to the welding rectangular tube 44, and the synchronization rod 49 is connected to the fixed beam 43 through a bearing seat 40.

[0051] After the mattress is packaged, it is necessary to take the mattress out of the mattress roll forming chamber 24 for transportation and storage.

[0052] Combination Fig.10 and Fig.11 To this end, the output assembly 5 includes an internal conveying assembly and an external conveying assembly. The internal conveying assembly has two groups, including a lifting mechanism 51 and a narrow and long conveying mechanism 52. The lifting mechanism 51 is connected to the narrow and long conveying mechanism 52 to drive the narrow and long conveying mechanism 52 to rise and fall; the narrow and long conveying mechanism 52 is used to lift the mattress that has been rolled and transported to the external conveying assembly. The narrow and long conveying mechanisms 52 of the two groups of the internal conveying assemblies include conveyor belts 521 that are arranged obliquely toward each other, and the conveyor belts 521 are connected to the internal conveying motor 522. The narrow and long conveying mechanism 52 that can be lifted and lowered can make full use of the free space in the rolling assembly 2, making the structure of the rolling machine of the present application more compact. The external conveying assembly includes an external conveying bracket 53, a guide bar 54 and an external conveyor belt 55; the external conveyor belt 55 is arranged on the external conveying bracket 53, and the guide bar 54 is arranged on both sides of the external conveyor belt 55. When the rolling and packaging are completed, the narrow and long conveying mechanism 52 rises, lifts the mattress from the electric roller assembly 23 and conveys it to the external conveying assembly; when the mattress reaches the external conveying assembly, the external conveyor belt 55 rotates to send the mattress to a predetermined centralized location for stacking.

[0053] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
