[0061] Refer to Figure 1 、 Figure 3 and Figure 5 As shown, it can be understood that in this embodiment, the connection base 310 is provided with a notch 312 communicating with the cavity 311, and the notch 312 is arranged between the two first connection holes 313.

[0062] Refer to Figure 1 、 Figure 3 and Figure 5As shown, specifically, the connecting seat 310 is provided with a notch 312 communicating with the cavity 311. When the connecting column passes through the first connecting hole 313 and the second connecting hole 430, the end of the connecting column is located in the cavity 311. The user can pass through the notch 312 to achieve the fixed connection between the limiting ring and the connecting column. The setting of the notch 312 is beneficial to increasing the operating space of the user, so as to improve the connection efficiency between the pressing plate 200 and the connecting seat 310.

[0063] Refer to Figure 1 , Figure 3 and Figure 5 As shown, specifically, notches 312 are provided at both the second enclosing plate and the fourth enclosing plate, and the notches 312 penetrate through the ends of the second enclosing plate or the fourth enclosing plate close to the opening of the cavity 311. The user can pass through the notches 312 to achieve the fixed connection between the limiting ring and the connecting column. The setting of the notches 312 is beneficial to increasing the operating space of the user, so as to improve the connection efficiency between the pressing plate 200 and the connecting seat 310.

[0064] Refer to Figure 1 , Figure 4 and Figure 5 As shown, it can be understood that specifically, the transfer mechanism 600 includes a lifting component 610. The lifting component 610 is located below the conveying surface 110 and is connected to the lower end of the connecting seat 310. Under the driving action of the lifting component 610, the pressing plate 200 can be lifted or lowered relative to the conveying surface 110, so that the pressing plate 200 can tightly press or separate from the mattress on the conveying surface 110, and cooperate with the externally provided folding component to achieve the folding process of the mattress.

[0065] Refer to Figure 1 , Figure 4 and Figure 5 As shown, specifically, the lifting component 610 can be a cylinder. The connecting seat 310 can be fixedly connected to the movable end of the cylinder through threaded parts such as bolts. Through the telescopic movement of the cylinder, the connecting seat 310 and the pressing plate 200 are driven to move up and down.

[0066] Refer to Figure 1 , Figure 4 and Figure 5 As shown, a groove is formed between two adjacent rotating rollers. The connecting seat 310 can be arranged to pass through the groove to avoid the problem that the lifting of the connecting seat 310 interferes with the rotation of the rotating rollers.

[0067] Considering that for a pneumatically driven cylinder, it is difficult to ensure the parallelism on both sides of the pressing plate 200, which is likely to cause the problem that the pressing plate 200 or the transfer mechanism 600 is stuck. The pressing device for folding the mattress enables the fastener 320 to move to a certain extent in the strip-shaped hole through the connection structure between the connecting seat 310 and the pressing plate 200, thereby avoiding the problem that the pressing plate 200 or the transfer mechanism 600 is stuck.

[0068] Refer to Figure 1 、 Figure 4 and Figure 5 As shown, it can be understood that specifically, the transfer mechanism 600 further includes a lateral movement component 620, and the lateral movement component 620 is connected to the lifting component 610 for driving the lifting component 610 to reciprocate along the width direction of the pressing plate 200. Under the driving action of the lateral movement component 620, the pressing plate 200 can be moved above the mattress on the conveying surface 110, and in cooperation with the lifting component 610, the pressing plate 200 can press the mattress. When the folding is completed, the pressing plate 200 is located in the middle of the folded mattress, and the lifting component 610 can drive the pressing plate 200 to separate from the mattress below. In cooperation with the operation of the lateral movement component 620, the pressing plate 200 can withdraw from the middle of the folded mattress. Through the cooperation of the lifting component 610 and the lateral movement component 620, the pressing plate 200 can be moved above the folded mattress, and the pressing plate 200 applies pressure to the folded mattress again to improve the folding effect of the mattress.

[0069] Refer to Figure 1 、 Figure 4 and Figure 5 As shown, specifically, the lateral movement component 620 includes a belt 622, a driving motor 625, and at least two belt pulleys 621. The two belt pulleys 621 are arranged at intervals along the width direction of the pressing plate 200. The belt pulleys 621 are rotatably connected to the material supporting frame 100. The belt 622 is wound between the two belt pulleys 621. The driving motor 625 is used to drive the belt pulleys 621 to rotate. The lifting component 610 is fixedly connected to the belt 622. By the forward driving and reverse driving of the driving motor 625, the lifting component 610 and the pressing plate 200 can be driven to reciprocate along the width direction of the pressing plate 200.

[0070] Refer to Figure 1 、 Figure 4 and Figure 5 As shown, the lateral movement component 620 further includes a guide rail 623 along the width direction of the pressing plate 200. The lifting component 610 is slidably connected to the guide rail 623. Through the slidable connection between the lifting component 610 and the guide rail 623, in cooperation with the connection between the belt 622 and the lifting component 610, the stability of the lateral movement of the lifting component 610 is ensured.

[0071] Refer to Figure 1 、 Figure 4 and Figure 5As shown, specifically, the slide rail, the lifting member 610, the belt 622 and at least two pulleys 621 together form a transfer member. Both ends of the pressing plate 200 are connected with the transfer members, and the transfer members at both ends are respectively connected with the connecting seats 310 at both ends. The transverse movement member 620 further includes a transmission shaft 624, and both ends of the transmission shaft 624 are respectively connected with the pulley 621 in the front and the pulley 621 in the rear. Taking the example that two groups of transfer members are arranged at intervals in the front and rear, the lifting member 610 in the front is slidably connected with the guide rail 623 in the front, and the lifting member 610 in the rear is slidably connected with the guide rail 623 in the rear. The driving motor 625 is connected with the transmission shaft 624 to drive the transmission shaft 624 to rotate, and then drive the two pulleys 621 in the front and rear to rotate synchronously, that is, drive the two lifting members 610 in the front and rear to move transversely synchronously.

[0072] Referring to Figure 1 、 Figure 2 and Figure 3 As shown, it can be understood that specifically, a roller shaft 500 is rotatably connected to the pressing plate 200, and the upper end of the roller shaft 500 is located above the upper end of the pressing plate 200. Under the driving action of the transfer mechanism 600, the pressing plate 200 is tightly pressed against the midline of the mattress. Cooperating with the external folding assembly, half of the mattress can be folded relative to the other half along the midline, that is, the mattress is folded in half. At this time, the pressing plate 200 is clamped in the middle of the folded mattress. Under the driving action of the lifting member 610, the pressing plate 200 can be separated from the mattress below, and the upper end of the roller shaft 500 is located above the upper end of the pressing plate 200. The roller shaft 500 abuts against the upper mattress. Through the rolling connection between the roller shaft 500 and the mattress, under the driving action of the transverse movement member 620, the pressing plate 200 can be withdrawn from the middle of the folded mattress. The setting of the roller shaft 500 is beneficial to reducing the lateral displacement of the mattress caused by the transverse movement of the pressing plate 200.

[0073] The packaging production line provided by the embodiment of the present invention includes a material pressing device for folding the mattress as shown in any one of the above embodiments.

Specifically, the pressing plate 200 is provided with at least two second connecting holes 430. One end of the connecting seat 310 is provided with a first connecting hole 313, and the first connecting hole 313 is disposed opposite to the second connecting hole 430. At least one of the first connecting hole 313 and the second connecting hole 430 is a horizontally arranged elongated hole. The fastener 320 is disposed through the first connecting hole 313 and the second connecting hole 430. By adjusting the position of the fastener 320 in the elongated hole, it is beneficial to compensate for the hole position deviation caused by assembly errors or processing errors. The transfer mechanism 600 is connected to the other end of the connecting seat 310. That is, through the connection function of the connecting component 300, the connection between the transfer mechanism 600 and the pressing plate 200 is realized, which is beneficial to avoid the problem of assembly failure caused by the pressing plate 200 being stuck. The material supporting frame 100 has a conveying surface 110 for conveying the mattress. The pressing plate 200 is located above the conveying surface 110 and is arranged parallel to the conveying surface 110. Under the driving action of the transfer mechanism 600, the pressing plate 200 is driven to approach or move away from the conveying surface 110. When the pressing plate 200 approaches the conveying surface 110, the pressing plate 200 can abut against the mattress on the conveying surface 110 to realize the tight pressing of the mattress. Cooperating with the external folding component, the folding of the mattress can be realized to reduce the packaging volume of the mattress. The flexible connection between the connecting component 300 and the pressing plate 200 of the material pressing device for folding a mattress is beneficial to reduce the assembly difficulty of the pressing plate 200, so as to facilitate the assembly of the pressing plate 200 and the transfer mechanism 600.
