[0036] As shown in Figs. 1 to 3 The present application provides a sponge cutting production line, which can belong to part of the existing sponge ring cutting system, specifically comprising a first conveying device 1, a vertical cutting device 2, a horizontal cutting device 3, a second conveying device 4, a clamping mechanism 5 and a driving mechanism 6.

[0037] The first conveying device 1 comprises a conveying frame 101, a conveying line 102 arranged on the conveying frame 101, and a forward and reverse motor 103 in driving connection with the conveying line 102 to make the conveying line 102 perform sponge conveying operation. The conveying line 102 can be composed of conveying rollers. When the conveying line 102 is composed of a plurality of conveying rollers arranged side by side on the conveying frame 101, the forward and reverse motor 103 can be in driving connection with the conveying rollers through a chain transmission mechanism (including a chain and a sprocket coaxially arranged with the conveying rollers). The structure of the second conveying device 4 can be the same as that of the first conveying device 1, and the second conveying device 4 is placed at the output end of the first conveying device 1.

[0038] The vertical cutting device 2 is arranged above the first conveying device 1 and can be used for vertically cutting the sponge located on the first conveying device 1 and the second conveying device 4. The vertical cutting device 2 can be a sponge cutting machine with constant number control model CNCHK-4. The horizontal cutting device 3 is arranged above the second conveying device 4 and can be a sponge cutting machine with constant number control model CNCHK-4, which is used for horizontally cutting the sponge after vertical cutting, so that the sponge can be cut into a sheet shape for winding by the winding device.

[0039] The clamping mechanism 5 is provided with two, respectively arranged on both sides of the length direction of the second conveying device 4. The driving mechanism 6 is in transmission connection with the clamping mechanism 5, for driving the clamping mechanism 5 to clamp the sponge and loosen the sponge.

[0040] When the sponge cutting operation is carried out, the sponge formed by the foaming process is conveyed to the lower side of the vertical cutting device 2 by the first conveying device 1, and the sponge is located on the first conveying device 1 and the second conveying device 4 at the same time; after the vertical cutting device 2 finishes the cutting operation, the driving mechanism 6 drives the clamping mechanism 5 to clamp the cut sponge, and then the forward and reverse motor 103 on the first conveying device 1 is controlled, so that the first conveying device 1 reverses to convey the sponge edge material left after the cutting operation back to the original input end of the first conveying device 1, so as to facilitate the production personnel to collect the sponge edge material. Compared with the existing sponge cutting equipment, after the sponge is vertically cut, the sponge edge material will not move with the sponge which has completed the vertical cutting, so that the subsequent horizontal cutting process of the sponge can be carried out normally, and the sponge piece meeting the production requirements can be cut.

[0041] And by arranging the clamping mechanism 5 on both sides of the length direction of the second conveying device 4, the clamping mechanism 5 is used to clamp the sponge after vertical cutting, which can prevent the cut sponge from moving with the sponge edge material, so that the cut sponge can only be conveyed to the lower side of the horizontal cutting device 3 by the second conveying device 4.

[0042] Optionally, the clamping mechanism 5 comprises a mounting bracket 51 and a clamping plate 52; the mounting bracket 51 can be installed on the rack of the second conveying device 4 through a threaded connecting piece (such as a bolt), and the driving mechanism 6 is arranged on the mounting bracket 51. The clamping plate 52 is vertically arranged and in transmission connection with the driving mechanism 6, so that the clamping plate 52 can be in contact with the surface of the vertically cut sponge, so that the two clamping plates 52 can clamp the sponge, and ensure that the cut sponge will not move with the sponge edge material.

[0043] Optionally, the driving mechanism 6 can be a pneumatic cylinder, and the extension rod of the pneumatic cylinder is connected with the back surface of the clamping plate 52.

[0044] Optionally, the clamping mechanism 5 further comprises a first guide rod 53 connected to the back of the clamping plate 52. The first guide rod 53 is provided with at least two, and is located on both sides of the telescopic rod of the air cylinder. The mounting bracket 51 is provided with a through hole for the horizontal passage of the first guide rod 53, so that the first guide rod 53 can be movably arranged on the mounting bracket 51. The arrangement of the first guide rod 53 can guide the movement of the clamping plate 52, prevent the clamping plate 52 from shaking or deviating during movement, and thus ensure that the sponge is clamped.

[0045] Optionally, the second conveying device 4 is provided with a guide assembly 7 on both sides in the length direction, and the two guide assemblies 7 are oppositely arranged and located between the vertical cutting device 2 and the horizontal cutting device 3. The guide assembly 7 is used for limiting the two sides of the sponge cut by the vertical cutting device, preventing the sponge from deviating from the correct travel path when traveling on the second conveying device 4, thereby ensuring the accuracy of the horizontal cutting of the sponge and making the specifications of the cut sponge meet the production requirements.

[0046] Optionally, the guide assembly 7 comprises a guide frame 71 and a plurality of vertical guide rollers 72 arranged side by side on the guide frame 71. The vertical guide roller 72 is rotatably connected with the guide frame 71, and when the side of the sponge contacts the vertical guide roller 72, the vertical guide roller 72 can rotate to adapt to the sponge, so that the friction between the side of the sponge and the vertical guide roller 72 is small, which is conducive to improving the quality of the sponge.

[0047] Optionally, the second conveying device 4 is provided with a support frame 8 on both sides in the length direction, and the guide assembly 7 is located between the two support frames 8. Further, the top of one of the support frames 8 is provided with a driving motor 9, the output shaft of the driving motor 9 is drivingly connected with a bidirectional screw rod 10 (the other end of the bidirectional screw rod 10 is installed on the top of the other support frame 8 through a bearing seat 13), the rod wall of the bidirectional screw rod 10 has two screw threads with opposite screw directions, and two nut seats 11 are respectively sleeved on the two screw threads, the nut seat 11 is fixedly arranged on the top of the guide frame 71 and connected with the screw thread.

[0048] When the driving motor 9 works, the bidirectional screw rod 10 rotates, so that the two nut seats 11 respectively threadedly connected with the two screw threads with opposite screw directions move towards each other or move away from each other (along the bidirectional screw rod 10), and the nut seat 11 is fixedly arranged on the top of the guide frame 71, so that when the two nut seats 11 move towards each other or move away from each other, the distance between the two guide assemblies 7 can be more conveniently adjusted, so that the guide assembly 7 can limit the sponge with different widths.

[0049] Optionally, two sides of the bidirectional screw rod 10 are provided with a second guide rod 12 parallel to the bidirectional screw rod 10, two ends of the second guide rod 12 are fixedly distributed on the top side of the support frame 8; the top side of the guide frame 71 is provided with a bearing seat 13 for the second guide rod 12 to pass through. The second guide rod 12 plays a role of guiding the guide frame 71, so that the guide assembly 7 does not deviate when moving, and the two guide assemblies 7 can always be in contact with the side surface of the sponge, thereby limiting the sponge.

[0050] In addition, the second guide rod 12 can also share the load borne by the bidirectional screw rod 10, so that the bidirectional screw rod 10 is not easy to break and damage.
