[0042] The following is combined with Figure 1-Figure 10 The present application is further described with specific embodiments:

[0043] First of all, it should be noted that in the description of this application, if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and other directional words appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application; in addition, if the terms "first", "second", "third" and other numerical quantifiers appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", and "connected" appear, they should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, a limited connection such as an interference fit, a transition fit, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown in Figure 10, a magnetic grabbing device for a paper pad 300 on a foaming machine includes: a plate body 2 that can be magnetically attracted, a rotating shaft 3, at least one limit block 4, at least one magnet 5, at least two hooks 6 and a hanging device 7.

[0045] At least two connecting blocks 21 are fixed on the plate body 2, and the connecting block 21 has a connecting portion 211 extending to the outside of the plate body 2; in the orthographic projection, the connecting portion 211 is completely outside the projection position of the plate body 2, and the rotating shaft 3 is rotatably connected to the connecting portion 211; the position of the rotating shaft 3 is at the side of the plate body 2, and the limit block 4 is fixed on the rotating shaft 3, and the limit block 4 can abut against the side of the plate body 2, so that the plate body 2 forms an angle α with the conveyor belt 200 of the foaming machine in the suspended state and the plate body 2 is inclined toward the conveying direction D, and the angle α is an acute angle. The limit block 4 will not contact the plate body 2 within the preset rotation range. After rotating to a predetermined angle, the limit block 4 will abut against the side of the plate body 2. The limit block 4 is limited relative to the plate body 2, and the acute angle is controlled between 30-60°. The magnet 5 can be magnetically connected to the plate body 2, and the magnet 5 and the plate body 2 can be used to clamp the pad paper 300; the hook 6 includes a hook portion 61 and a rod portion 62, the rod portion 62 is fixedly connected to the rotating shaft 3, and the rod portion 62 can abut against the plate body 2 so that a gap 63 is formed between the hook portion 61 and the conveyor belt 200 of the foaming machine in the placed state; the hanging device 7 includes a driving device 71 and a hanging rod 72, the hanging rod 72 can enter the hook groove 611 of the hook portion 61, and the entrance direction of the groove is set downward, so that the hook 6 can be hung on the hanging rod 72, and the driving device 71 can drive the hanging rod 72 to rise and fall.

[0046] In the present application, as shown in FIG. 10 , the magnet 5 can be placed on the conveyor belt 200 first, and then the padding paper 300 can be placed on the conveyor belt 200 so that the end of the padding paper 300 is pressed on the magnet 5, and then the plate body 2 can be placed on the padding paper 300 and magnetically connected to the magnet 5; or the magnet 5 can be placed on the padding paper 300 first, and then the end of the padding paper 300 can be folded to cover the magnet 5, and then the plate body 2 can be pressed tightly on the folded padding paper 300 and magnetically connected to the magnet 5. The second case is preferably selected for setting.

[0047] The hook portion 61 of the hook 6 on the plate body 2 is arranged toward the conveying direction D. When the foaming machine is foaming, the driving device 71 first drives the hanging rod 72 to drop to a position lower than the hook portion 61. At this time, the conveyor belt 200 drives the hook 6 to translate, so that the hook portion 61 is automatically hooked on the hanging rod 72. The subsequent driving device 71 drives the hanging rod 72 to rise, and the padding paper 300 can be driven to rise together. When the foamed sponge 400 moves to this position, the padding paper 300 will automatically cover the sponge 400, and then continue to move, and the padding paper 300 will automatically detach from between the magnet 5 and the plate body 2, while the magnet 5 is still magnetically attracted to the plate body 2, thereby realizing that the padding paper 300 automatically covers the sponge 400. The present application can be improved on the existing sponge continuous foaming machine.

[0048] Fig.10 In the middle, a is a pad paper 300 disposed on the conveyor belt 200, a portion of the pad paper 300 has been clamped between the magnet 5 and the plate body 2, and the hook 6 is not connected to the hanging rod 72; Fig.10 b is the initial contact and connection state between the hook 6 and the hanging rod 72; Fig.10 Figure c is a schematic diagram of the plate body 2 being hung by the hanging rod 72; Fig.10 d is a schematic diagram showing that the padding paper 300 is separated from between the magnet 5 and the plate 2 and the padding paper 300 has covered the sponge 400 .

[0049] The device can automatically cover the pad paper 300 without manual covering, thus improving safety. When the hook portion 61 is hooked on the hanging rod 72, the hook 6 rotates in the direction opposite to the conveying direction D until the limit block 4 abuts against the side of the plate body 2. In the hanging state, the plate body 2 and the conveyor belt 200 of the foaming machine form an angle α and the plate body 2 is tilted toward the conveying direction D, which facilitates the subsequent removal of the pad paper 300 from between the magnet 5 and the plate body 2, thereby reducing the possibility of the magnet 5 falling off.

[0050] Taking into account the stability during the lifting process, in the present application, two hooks 6 are provided, and two drive devices 71 are also provided, so that the hanging rod 72 can be lifted and lowered stably.

[0051] In the placed state, a gap 63 is formed between the hook-shaped portion 61 and the conveyor belt 200 of the foaming machine, so that the hanging rod 72 can smoothly enter the hook groove 611 of the hook-shaped portion 61 .

[0052] In this application, if Figure 3 As shown, the hanging state is a state in which the plate body 2 is completely lifted by the hanging rod 72 and has been separated from the conveyor belt 200. Figure 2 As shown, the placement state is that the plate body 2 is not contacted by the hanging rod 72 and is placed on the conveyor belt 200 in a natural state.

[0053] Specifically, Figure 2 , Figure 3 As shown, a stopper rod 64 is fixed on the hook 6 , and an inlet 65 for the hanging rod 72 to enter is formed between the stopper rod 64 and the free end of the hook portion 61 , and the inlet 65 is communicated with the hook groove 611 of the hook portion 61 .

[0054] The inlet 65 formed between the stopper 64 and the free end of the hook 61 provides a clear entry passage for the hanging rod 72. When the conveyor belt 200 drives the hook 6 to move, the hanging rod 72 can more easily enter the hook groove 611 of the hook 61 through the inlet 65 under the guidance of the stopper 64, and the hook 6 can quickly and accurately hook the hanging rod 72. During the lifting and lowering process of the hanging rod 72, it only needs to move to the position corresponding to the stopper 64 without being particularly precise.

[0055] Specifically, in the placed state, the blocking rod 64 is perpendicular to the conveying belt 200 of the foaming machine or the hanging rod 72 and is inclined toward the conveying direction D.

[0056] The vertically or obliquely arranged hanging rod 72 enables the hook 6 to smoothly enter the connection state when it contacts the hanging rod 72. This design reduces the jamming, connection failure, and even the flipping of the plate 2 caused by the inappropriate angle between the hanging rod 72 and the hook 6.

[0057] like Figure 1 , Figure 2 , Fig.10 As shown, the blocking rod 64 is perpendicular to the conveyor belt 200 of the foaming machine. The inclined hanging rod 72 is not shown in the figure.

[0058] Specifically, Figure 1 , Fig.10 As shown, the driving device 71 includes a guide rail 711, a slide bar 712, a chain 713, a guide wheel 714, a gear 715, and a driving motor 716. The guide rail 711 is used to be fixed on the top of the box body 100 of the foaming machine; the slide bar 712 is slidably installed on the guide rail 711; one end of the chain 713 is fixedly connected to the slide bar 712, and the other end is fixedly connected to the hanging rod 72; the guide wheel 714 is used to be rotatably arranged on the top of the box body 100 of the foaming machine, and the chain 713 is wound on the guide wheel 714; the slide bar 712 is provided with a rack 7121 along the conveying direction D, and the slide bar 712 can move back and forth along the conveying direction D; the gear 715 is meshed with the rack 7121, and the driving motor 716 is transmission-connected to the gear 715, so as to drive the gear 715 to rotate.

[0059] After the driving motor 716 is started, the gear 715 is driven to rotate. Since the gear 715 is meshed with the rack 7121 on the slide bar 712, the slide bar 712 moves back and forth along the conveying direction D on the guide rail 711. When the slide bar 712 moves, the hanging rod 72 is driven to rise and fall through the chain 713. When the hook 6 needs to be hooked to the hanging rod 72, the driving motor 716 drives the slide bar 712 to move so that the hanging rod 72 drops to a position lower than the hook-shaped portion 61. As the conveyor belt 200 drives the hook 6 to move horizontally, the hook-shaped portion 61 automatically hooks on the hanging rod 72. Then, the driving motor 716 is reversed, driving the slide bar 712 to move in the opposite direction, and the hanging rod 72 is raised through the chain 713, thereby driving the pad paper 300 to rise together.

[0060] In the present application, the driving motor 716 and the gear 715 are connected and driven via other chain gear structures.

[0061] The cooperation of the guide rail 711 and the slide bar 712 makes the movement of the slide bar 712 more stable, and the chain 713 is wound around the guide wheel 714 and connected with the slide bar 712 and the hanging rod 72, ensuring the stability of the lifting process of the hanging rod 72. In addition, the arrangement of the guide rail 711 and the slide bar 712 can reduce the occupied space and can be directly installed on the top wall of the box 100 in the existing foaming machine.

[0062] Specifically, Figure 5 As shown, there are multiple magnets 5 distributed on the plate body 2 .

[0063] In the present application, a plurality of magnets 5 are provided and arranged in three rows, and the three rows of magnets 5 are staggered.

[0064] Specifically, Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, the plate body 2 includes a plate member 22 that can be magnetically attracted and a shell member 23 that cannot be magnetically attracted. The shell member 23 has a chamber 231. The plate member 22 is arranged in the shell member 23, and the connecting block 21 is fixed on the shell member 23. A slide groove 221 corresponding to the limit block 4 is opened at the bottom of the plate member 22. A slider 24 is slidably arranged on the shell member 23, and the slider 24 corresponds to the slide groove 221. At least two first guide blocks 223 are fixed to the inner bottom of the slide groove 221, and a first guide block 223 is fixed on the slider 24. The second guide block 241 corresponding to the first guide block 223, when the slider 24 moves toward the limit block 4, the second guide block 241 abuts against the first guide block 223 and moves the plate 22 in the direction away from the magnet 5; a rope 25 is fixed to the slider 24, and a connecting member 42 is fixed to the limit block 4, and the connecting member 42 is detachably connected to the free end of the rope 25, wherein when the rope 25 is connected to the connecting member 42, the rotation of the limit block 4 can drive the slider 24 to move toward the limit block 4.

[0065] In the present application, since the plate body 2 and other components are heavy as a whole and require multiple people to operate, a specific structure is designed to reduce the workload.

[0066] When the hook portion 61 of the hook 6 is connected to the hanging rod 72 and the magnet 5 needs to be set on the conveyor belt 200 or the pad paper 300 , one end of the rope 25 can be connected to the limit block 4 .

[0067] When the hanging rod 72 moves up and drives the hook 6 to rotate, the limit block 4 rotates synchronously. Since the free end of the rope 25 is connected to the connecting piece 42 on the limit block 4, the limit block 4 will drive the rope 25 to move, and then the rope 25 pulls the slider 24 to slide in the direction of the limit block 4. During the movement of the slider 24, the second guide block 241 on the slider 24 abuts against the first guide block 223 in the bottom slide groove 221 of the plate 22, so that the plate 22 moves in the direction away from the magnet 5 under the action of the slider 24, thereby reducing the suction force of the magnet 5 on the plate 22, and the magnet 5 automatically falls on the conveyor belt 200 or the pad paper 300 under the action of gravity, completing the setting of the magnet 5. In this way, there is no need to manually remove the magnet 5 from the plate body 2, which greatly improves efficiency. Further, the plate 22 is a steel plate or an iron plate, and preferably, the plate 22 is a steel plate.

[0068] When it is necessary to drive the pad paper 300 to move upward, the connection between the rope 25 and the connecting member 42 can be released. After the connection is released, the plate member 22 can automatically return to its original position under the action of gravity.

[0069] Furthermore, an escape groove 222 for escaping the connection block 21 is opened on the upper portion of the plate 22 .

[0070] Specifically, Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, the limiting block 4 is provided with a limiting groove 41 , the rope 25 can be placed in the limiting groove 41 , the connecting member 42 is fixed in the limiting groove 41 , and the shell part 23 is provided with a through hole 232 , and the rope 25 passes through the through hole 232 .

[0071] The limiting groove 41 on the limiting block 4 provides a specific placement position for the rope 25, so that the rope 25 will not shake or shift at will during operation, thereby ensuring the stability of the operation of the entire device. The through hole 232 on the shell part 23 provides a reasonable channel for the rope 25, so that the slider 24 can be more stable when the rope 25 is pulled. The through hole 232 is arranged on one side of the corresponding slider 24, so that the rope 25 between the through hole 232 and the slider 24 is in the sliding direction of the slider 24.

[0072] The connecting piece 42 is fixed in the limiting groove 41 so as to be hidden and more beautiful from the outside.

[0073] Specifically, Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, the connecting member 42 is a connecting ring, and a connecting hook 251 is fixed to one end of the rope 25, and the connecting hook 251 can hook the connecting ring.

[0074] The combination of the connecting ring and the connecting hook 251 makes the connection between the rope 25 and the limiting block 4 very convenient and quick. When connection is needed, the connecting hook 251 only needs to be easily hooked on the connecting ring, without complicated operations and tools, which greatly improves work efficiency.

[0075] Specifically, Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the limit block 4 has a support portion 43 with an arc-shaped surface. When the limit block 4 is against the side of the plate body 2, the support portion 43 is lower than the lower surface of the plate body 2, so that the support portion 43 can contact the conveyor belt 200 and the side of the plate body 2 close to the support portion 43 is suspended.

[0076] When the magnet 5 on the plate body 2 needs to be placed on the conveyor belt 200 or the pad paper 300 , the connecting piece 42 is connected to the rope 25 .

[0077] The hanging rod 72 moves up and drives the hook 6 to rotate. The limit block 4 has an arc-shaped support portion 43, which can abut against the conveyor belt 200 or the pad paper 300, so that one end of the plate body 2 leaves the conveyor belt 200 or the pad paper 300 in advance, so that the magnet 5 is separated from the plate body 2 and remains on the conveyor belt 200 or the pad paper 300. After being lifted by the hanging rod 72, the plate body 2 has basically no contact with the magnet 5, which will not cause the position of the magnet 5 to shift, and there is basically no need to adjust the position of the magnet 5.

[0078] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. Although the present application has been described in detail in this specification with reference to the above embodiments, a person of ordinary skill in the art should understand that a person of ordinary skill in the art can still modify or make equivalent substitutions to the present application, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
