[0027] 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.

[0028] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a bed net wrapping machine, comprising an upper pre-pressing mechanism 1, a wrapping mechanism 2 and a discharging mechanism 3; the upper pre-pressing mechanism 1 is used for feeding and pre-pressing a mattress, and comprises an upper conveying mechanism 11 and a pre-pressing mechanism 12 arranged above the upper conveying mechanism 11, the upper conveying mechanism 11 is provided with a lower conveying belt 111, the pre-pressing mechanism 12 is provided with an upper conveying belt 121, the upper conveying belt 121 is arranged at a certain angle with the lower conveying belt 111, and the upper conveying belt 121 can follow the pre-pressing mechanism 12 as a whole and translate along the feeding direction;

[0029] The rolling mechanism 2 is used to roll the mattress into a roll, and includes a main roller 21 and a main roller driving mechanism 22;

[0030] The discharging mechanism 3 is used to deliver the completed mattress, and includes a push plate 31, a push plate driving mechanism 32 and a mattress conveying mechanism 33. The push plate 31 is arranged on one side of the main roller 21, and the push plate driving mechanism 32 is used to drive the push plate 31 to move from one side of the main roller 21 to the other side. The mattress conveying mechanism 33 is arranged on one side of the rolling mechanism 2, and is used to carry the mattress pushed out from the main roller 21 and transport it to a predetermined position.

[0031] With this solution, the mattress is fed through the upper pre-pressing mechanism 121. The pre-pressing mechanism 12 is provided with an upper conveyor belt 121, and the upper conveyor belt 121 is arranged at a certain angle with the lower conveyor belt 111, and the upper conveyor belt 121 can follow the pre-pressing mechanism 12 as a whole and translate in the feeding direction. When feeding, the upper conveyor belt 121 can move between the front feeding station and the rear feeding station. When at the front feeding station, the distance between the upper conveyor belt 121 and the lower conveyor belt 111 is far, which is convenient for the uncompressed mattress to enter. Then the upper conveyor belt 121 and the lower conveyor belt 111 rotate in coordination to convey the mattress to the winding mechanism 2. During this process, the upper conveyor belt 121 will also move in the direction of the winding mechanism 2, so that the distance between the upper conveyor belt 121 and the lower conveyor belt 111 gradually decreases, and the mattress is gradually compressed.

[0032] After the above pre-pressing process, the mattress sent to the rolling mechanism 2 has been fully compressed, the stress of the main roller 21 during the rolling process is small, and the quality of the mattress rolling is good. In addition, after the pre-pressing, the mattress can be directly sent to the main roller 21 through the movement of the upper conveyor belt 121, without manual intervention, saving manpower and improving work efficiency.

[0033] Preferably, combined Figure 3The upper push conveying mechanism 11 includes an upper push arm 112 and an upper push cylinder 113. One side of the upper push arm 112 is hinged to the frame 114, and the other side is connected to the upper push cylinder 113. The upper push arm 112 can be driven to swing up and down by the extension and contraction of the upper push cylinder 113; the lower conveyor belt 111 is arranged on the upper push arm 112, and swings up and down following the upper push arm 112. The swingable upper push arm 112 can ensure that the corresponding wrapping part of the lower conveyor belt 111 always applies a predetermined pressing force to the main roller 21, thereby ensuring the wrapping quality. In order to make the wrapping part of the lower conveyor belt 111 adapt to the contour of the main roller 21, the upper push arm 112 has an arc-shaped portion 115, and a support roller 116 arranged along the arc-shaped portion is provided below the lower conveyor belt 111. Under the action of the supporting roller 116, the wrapping portion of the lower conveyor belt 111 is in an arc shape, so that the mattress can be automatically wrapped around the main roller 21 during the wrapping process to complete the wrapping work.

[0034] In order to realize the movement of the upper conveyor belt 121, the pre-pressing mechanism 12 includes a guide column 122 fixedly arranged on the upper top arm 112, a sliding sleeve 123 arranged on the guide column 122, a pre-pressing cylinder 124 driving the sliding sleeve 123 to slide along the guide column 122, and a pre-pressing seat 125 connected to the sliding sleeve 123; the upper conveyor belt 121 is arranged on the pre-pressing seat 125. One end of the pre-pressing cylinder 124 is connected to the upper top arm 112, and the other end is connected to the pre-pressing seat 125. When the pre-pressing cylinder 124 is extended or retracted, the pre-pressing seat 125 can be driven to move relative to the guide column 122.

[0035] like Figure 4 and Figure 5 As shown, the main roller 21 is arranged on a rotating shaft 23. In order to fix the woven cloth on the main roller 21, a vent hole 24 is arranged on the surface of the main roller 21, and a vent channel (not shown) is arranged in the center of the rotating shaft 23, which is connected to the vent hole 24 and is also connected to an exhaust fan 25. When the exhaust fan 25 is working, air is drawn out from the vent channel, so that a negative pressure is formed at the vent hole 24, thereby sucking the woven cloth placed on the surface of the main roller 21.

[0036] After the wrapping is completed, the mattress needs to be pushed out from the main roller 21 by the push plate 31. The push plate driving mechanism 32 includes a guide screw 321 and a screw motor 322; the push plate 31 is arranged on the guide screw 321, and the screw motor 322 is connected to the guide screw 321 through a reduction box 323, and the push plate 31 is driven to move along the axial direction of the main roller 21 by driving the guide screw 321 to rotate; the push plate 31 is provided with an avoidance hole 311 in the center to allow the main roller 21 to pass through.

[0037] Preferably, combined Figure 6 and Figure 7 The mattress conveying mechanism 33 includes a base frame 331 and a lifting platform 332, and the lifting platform 332 can be lifted relative to the base frame 331. The lifting platform 332 includes a roller frame 333, a roller 334 arranged on the roller frame 333, a lifting column 335 arranged at the four corners of the roller frame 333, and a lifting motor 336; a nut 337 is provided on the base frame 331, and the lifting column 335 is arranged in cooperation with the nut 337; the lifting motor 336 is connected to the lifting column 335 and can drive the lifting column 335 to rotate. Since the lifting platform 332 can be lifted and lowered, when the mattress is pushed out, the lifting platform 332 is in a high position, providing reliable support for the mattress and preventing the mattress from deforming; when the mattress is completely pushed out, the lifting platform 332 descends, which is convenient for subsequent strapping and transportation. The roller frame 333 is provided with a roller 334, which is convenient for strapping work to be performed directly on the lifting platform 332.

[0038] In order to smoothly transfer the woven fabric, Figure 8 As shown, the wrapping machine also includes a woven cloth conveying mechanism 4, which includes a placement rack 41 and cloth guide rollers (42a, 42b), the placement rack 41 is used to place the woven cloth 5, and the cloth guide rollers (42a, 42b) are arranged below the upper pre-pressing mechanism 121 and in front of the lower conveyor belt 111, and are used for guiding the transmission of the woven cloth.

[0039] Preferably, the upper conveyor belt 121 and the lower conveyor belt 111 are driven by independent drive motors (117, 126). The drive motors (117, 126) can provide different driving forces and driving speeds for the upper conveyor belt 121 and the lower conveyor belt 111, so that the mattress can still be reliably clamped and transferred during the relative movement of the upper conveyor belt 121 and the lower conveyor belt 111.

[0040] The following is a detailed description of how this application works:

[0041] 1. Preparation of woven fabric. Place the woven fabric for packaging on the placement rack 41, and place the woven fabric along the first fabric guide roller 42a and the second fabric guide roller 42b, through the surface of the lower conveyor belt 111, and then on the surface of the main roller 21. The vents 24 on the main roller 21 will suck the woven fabric, and the main roller 21 will rotate to make the woven fabric roll around the main roller 21 for several turns. The woven fabric is ready.

[0042] 2. Loading and pre-compression. The mattress is transported to the lower conveyor belt 111 by means of a conveyor belt or other equipment, and the piston rod of the pre-compression cylinder 124 is retracted, so that the upper conveyor belt 121 is located at the front feeding station, where the distance between the upper conveyor belt 121 and the lower conveyor belt 111 is relatively large, and the mattress can be fed between the upper conveyor belt 121 and the lower conveyor belt 111 autonomously; then the piston rod of the pre-compression cylinder 124 is extended, and the upper conveyor belt 121 and the lower conveyor belt 111 rotate under the drive of independent drive motors, clamping the mattress and gradually compressing it.

[0043] 3. Rolling. The piston rod of the pre-pressing cylinder 124 is fully extended, and the upper conveyor belt 121 reaches the rear feeding station. As the upper conveyor belt 121 and the lower conveyor belt 111 continue to rotate, the mattress passes through the arc-shaped portion 115 area of ​​the upper top arm 112, and is sent to between the arc-shaped portion 115 and the main roller 21. The main roller drive mechanism 22 drives the main roller 21 to rotate for rolling. Since the main roller 21 and the lower conveyor belt 111 are already arranged with woven cloth in advance, the woven cloth will fit the surface of the mattress during the mattress rolling process; after the mattress is rolled, the woven cloth at the end will be wrapped around the mattress surface for multiple turns to fix the mattress.

[0044] 4. Pushing the material. After the wrapping is completed, the limit plate 6 on one side of the main roller 21 is opened, the screw motor 322 rotates, and the guide screw 321 is driven to rotate through the reduction box 323. The push plate 31 is provided with a thread that matches the guide screw 321. Therefore, when the guide screw 321 rotates, the push plate 31 can be pushed to move axially toward the main roller 21. The push plate 31 moves from one end of the main roller 21 to the other end, and pushes out the wrapped mattress on the surface of the main roller 21.

[0045] 5. Material discharging and packaging. During the material pushing process, the lifting platform 332 located on one side of the wrapping mechanism 2 rises to provide reliable support for the mattress to prevent the mattress from deformation; when the mattress is completely pushed out, the lifting platform 332 descends to facilitate subsequent strapping and transportation. The roller bar frame 333 is provided with a roller bar 334 to facilitate the strapping work directly on the lifting platform 332. The strapped mattress is transported to a predetermined location by a forklift and other equipment for storage, waiting for shipment.

[0046] 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.
