[0003] Currently, there are two common methods for breaking foam: press and roller. The press method is mainly used for thick foam materials and has low efficiency, and is even less efficient when used for thin materials.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] In the description of the present invention, it should be clarified that the terms "vertical", "transverse", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal", etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not mean that the device or element referred to must have a specific orientation or position. Therefore, they cannot be understood as limiting the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] Example 1

[0036] This embodiment 1 provides a V-shaped top pressure double conveyor belt continuous bubble breaking device, such as Figure 1 As shown, it includes a frame 1, the V-shaped angle conveying component 2 and the horizontal conveying component 3. The V-shaped angle conveying component 2 and the horizontal conveying component 3 are both arranged on the frame 1. The V-shaped angle conveying component 2 is located above the horizontal conveying component 3, and a closed feeding end and a flared discharge end are formed between it and the horizontal conveying component 3. The distance between the bending part of the V-shaped angle conveying component 2 and the horizontal conveying component 3 is adjustable.

[0037] Compared with the prior art, the present invention arranges the V-shaped angled conveying component 2 above the horizontal conveying component 3, and forms a closed feeding end and a flared discharging end between the V-shaped angled conveying component 2 and the horizontal conveying component 3. The feeding end is gradually pressurized and the discharging end is gradually depressurized. The pressure on the foam material will not change suddenly, thereby avoiding damage to the foam material. Moreover, by adjusting the distance between the bending part of the V-shaped angled conveying component 2 and the horizontal conveying component 3, foam materials with different thicknesses and different compression rate requirements during foam breaking can be broken, and the versatility is stronger.

[0038] In one embodiment, Figure 1 As shown, the horizontal conveying assembly 3 includes a horizontal conveyor belt 31 and a support rod group 32. The horizontal conveyor belt 31 is arranged at one end of the support rod group 32, and the other end of the support rod group 32 is fixed to the frame 1. The length of the support rod group 32 is adjustable, and the bending part of the V-shaped angle conveying assembly 2 is fixed relative to the frame 1. Therefore, by adjusting the length of the support rod group 32, the horizontal conveying can be raised and lowered, that is, the distance between the bending part of the V-shaped angle conveying assembly 2 and the horizontal conveyor belt 31 can be adjusted. At the same time, the part of the horizontal conveyor belt 31 located directly below the bending part of the V-shaped angle conveying assembly 2 is the part with the greatest pressure, and the support rod group 32 should focus on supporting this part.

[0039] In one embodiment, Figure 1 、 Figure 5 As shown, the V-shaped angled conveying assembly 2 includes a squeeze roller 23, a first drive roller 21, a second drive roller 22, and a belt 25. The squeeze roller 23, the first drive roller 21, and the second drive roller 22 are arranged in a V-shape on the frame 1, with the squeeze roller 23 located at the bend of the V-shape. The belt 25 is arranged around the squeeze roller 23, the first drive roller 21, and the second drive roller 22. The rotating shafts of the first drive roller 21 and the second drive roller 22 are connected to a variable frequency drive motor, for example, by a gear set, a chain sprocket, or the like. Those skilled in the art can select a specific method based on actual conditions, and will not be described in detail here.

[0040] Furthermore, if Figure 5、 6 As shown in Figures 7 and 8, the V-shaped angle conveying assembly 2 also includes a first guide frame 26 and a second guide frame 27. The first guide frame 26 includes a bracket 261 and a guide plate 262. The two ends of the bracket 261 are rotatably connected to the rotating shafts of the squeezing roller 23 and the first driving roller 21 respectively, and the guide plate 262 is fixed on the side of the bracket 261 close to the belt 25; the second guide frame 27 has the same structure as the first guide frame 26, and its two ends are rotatably connected to the rotating shafts of the squeezing roller 23 and the second driving roller 22 respectively.

[0041] Since the belt 25 has a certain elasticity and is easily deformed by the reaction force of the foam material, a guide frame is added. The belt 25 will slide along the guide plate 262 during operation. The guide plate 262 itself has a large rigidity, which can offset the reaction force of the foam material, avoid deformation of the belt 25, and provide sufficient downward pressure.

[0042] Furthermore, if Figure 6 、 7 As shown, a plurality of raised rolling bodies 263 are provided on the side of the guide plate 262 close to the belt 25. The rolling bodies 263 can be cylinders or spheres, slightly protruding from the surface of the guide plate 262 to reduce the friction resistance between the belt 25 and the guide plate 262.

[0043] In one embodiment, Figure 4 As shown, the frame 1 is provided with a fixed mounting hole 13, and a first arc chute 11 and a second arc chute 12 symmetrically arranged on both sides of the fixed mounting hole 13 with the center of the fixed mounting hole 13 as the center of the circle (the first arc chute 11 and the second arc chute 12 are symmetrically arranged about the vertical plane passing through the axis of the fixed mounting hole 13), the first arc chute 11 and the second arc chute 12 are respectively provided with a first support 15 and a second support 16 that can move along the corresponding arc chute and can be fixed at any position in the corresponding arc chute, the rotating shaft of the first driving roller 21 is installed on the first support 15, the rotating shaft of the second driving roller 22 is installed on the second support 16, and the rotating shaft of the squeezing roller 23 is installed in the fixed mounting hole 13.

[0044] By adjusting the position of the first support 15 in the first circular chute 11 and the position of the second support 16 in the second circular chute 12, the V-shaped angle formed by the first drive roller 21, the squeeze roller 23, and the second drive roller 22 can be adjusted. This is equivalent to adjusting the angle β between the V-shaped angle conveying assembly 2 and the flat conveyor belt. The central angle corresponding to the first circular chute 11 and the second circular chute 12 is 45°, i.e., 0 < β < 45°.

[0045] Furthermore, if Figure 1 、 4As shown in Figure 5, the V-shaped angle conveying assembly 2 also includes a tension adjusting roller 24 for adjusting the tension of the belt 25. A vertical slide 14 is provided on the frame 1. The vertical slide 14 is located directly above the fixed mounting hole 13. The vertical slide 14 is provided with a third support 17 that can move along the vertical slide 14 and can be fixed at any position in the vertical slide 14. The rotating shaft of the tension adjusting roller 24 is installed on the third support 17.

[0046] Specifically, the tension adjustment roller 24 abuts against the outer surface of the belt 25, which is equivalent to the tension adjustment roller 24 being located above the belt 25. When the tension adjustment roller 24 moves downward, the belt 25 is tightened, and when the tension adjustment roller 24 moves upward, the belt 25 is relaxed. The belt 25 is also V-shaped under its restriction, which is conducive to reducing the overall height of the bubble breaking device.

[0047] Furthermore, if Figure 3 As shown, the first support 15 includes a connecting portion 151, and an inner flange 152 and an outer flange 153 respectively fixed at both ends of the connecting portion 151. The connecting portion 151 is embedded in the first circular arc chute 11 and is provided with a central mounting hole 154. The rotating shaft of the first driving roller 21 is mounted in the central mounting hole 154. The diameters of the inner flange 152 and the outer flange 153 are larger than the width of the first circular arc chute 11. The inner flange 152 is located on the inner side of the frame 1, and the outer flange 153 is located on the outer side of the frame 1. The outer flange 153 is provided with multiple screw holes 155, each of which is provided with a fastening bolt 156. After tightening the fastening bolt 156, the frame 1 is clamped between the front end of the fastening bolt 156 and the inner flange 152, thereby fixing the position of the first support 15.

[0048] In addition, in order to improve the versatility of components and facilitate maintenance, the widths of the first arc chute 11, the second arc chute 12, and the vertical chute 14 are the same, the structures of the first support 15, the second support 16, and the third support 17 are the same, the structures of the second guide frame 27 and the first guide frame 26 are the same, and the diameters of the rotating shafts of the first drive roller 21, the second drive roller 22, and the tension adjustment roller 24 are the same.

[0049] The present invention arranges the V-shaped angle conveying component 2 above the horizontal conveyor belt 31, and forms a closed feeding end and a flared discharging end between it and the horizontal conveying component 3. The feeding end is gradually pressurized and the discharging end is gradually decompressed. The pressure on the foam material will not change suddenly, thereby avoiding damage to the foam material. The distance between the extrusion roller 23 and the horizontal conveyor belt 31 can be adjusted by adjusting the length of the support rod group 32. The angle β between the belt 25 and the plane conveyor belt can also be adjusted by adjusting the position of the first support 15 in the first circular arc chute 11 and the position of the second support 16 in the second circular arc chute 12 (the first support 15 and the second support 16 are symmetrically arranged about the vertical plane passing through the axis of the fixed installation hole 13). Foam materials with different thicknesses and different compression rate requirements during foaming can be broken, and the versatility is stronger.

[0050] In addition, the foam breaking device is also designed with a flat conveying component on the top and a V-shaped angled conveying component on the bottom, or two V-shaped angled conveying components are symmetrically arranged up and down. The above two structures can form a closed-end feeding end and an expanded-end discharging end, thereby breaking the foam material.

[0051] Example 2

[0052] This embodiment 2 also provides a V-shaped top pressure double conveyor belt continuous bubble breaking device. The difference from embodiment 1 is that the V-shaped top pressure double conveyor belt continuous bubble breaking device in this embodiment 2 completely fixes the horizontal conveying component 3 on the ground, and after the V-shaped angled conveying component 2 is set on the frame 1, the bottom of the frame 1 is fixed on the ground, and the frame 1 can be raised and lowered. The rest of the structure is the same as that of embodiment 1, and the distance between the bending point of the V-shaped angled conveying component 2 and the horizontal conveying component 3 can also be adjusted.

[0053] Example 3

[0054] This embodiment 3 provides a V-shaped top pressure double conveyor belt continuous bubble breaking method, which is applicable to the V-shaped top pressure double conveyor belt continuous bubble breaking device described in embodiments 1-2. The V-shaped top pressure double conveyor belt continuous bubble breaking method includes:

[0055] Adjust the distance between the bend of the V-shaped angle conveying assembly 2 and the horizontal conveying assembly 3 to be equal to the minimum thickness required for the foam material to break;

[0056] Measure the angle β between the V-shaped angle conveying component 2 and the horizontal conveying component 3;

[0057] Start the V-shaped angle conveying component 2 and the horizontal conveying component 3;

[0058] According to the angle β between the V-shaped folding conveying assembly 2 and the horizontal conveying assembly 3, the conveying speed v1 of the V-shaped folding conveying assembly 2 and the conveying speed v2 of the horizontal conveying assembly 3 are controlled, specifically: v2 = v1 × cosβ, to prevent the foam material from rolling;

[0059] The foam material is placed on the horizontal conveying component 3 at the feed end and continuous foam breaking is started.

[0060] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
