DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] Embodiment 1

[0030] like Figure 1-Figure 4 As shown, the bubble pressing machine includes a frame 1, on which a lower bubble pressing roller 20 and an upper bubble pressing roller 21 located above the lower bubble pressing roller 20 are provided, the lower bubble pressing roller 20 or the upper bubble pressing roller 21 is connected to a rotation driving device 3, and the lower bubble pressing roller 20 and the upper bubble pressing roller 21 are connected through a gear transmission assembly 4, the frame 1 has a U-shaped bracket 10 formed by bending a metal plate, the U-shaped bracket 10 is formed by a sheet metal process, and bubble pressing roller fixing seats 11 are respectively provided on opposite sides of the U-shaped bracket 10, the two ends of the lower bubble pressing roller 20 are respectively rotatably connected to the bubble pressing roller fixing seats 11, and the two ends of the upper bubble pressing roller 21 are respectively rotatably connected to the bubble pressing roller fixing seats 11.

[0031] Nail holes 15 are respectively provided on the opposite sides of the U-shaped bracket 10, and the nail holes 15 provided on one side of the U-shaped bracket 10 and the nail holes 15 provided on the other side of the U-shaped bracket 10 are one-to-one corresponding and coaxial, and fasteners threadedly connected to the nail holes 15 are passed through the foam roller fixing seat 11, and the fasteners are, for example, bolts, screws, etc. The U-shaped bracket 10 formed by bending the metal plate can ensure that the positions of the two foam roller fixing seats 11 are symmetrically distributed, so that the upper foam roller 21 and the lower foam roller 20 can be parallel to each other and at the same angle on the vertical plane.

[0032] The U-shaped bracket 10 formed by bending a metal plate provides a solid supporting structure, making the entire frame 1 more solid and stable, which is beneficial to maintaining the stability of the machine during operation. The frame 1 adopts a U-shaped bracket design, so that the foam roller fixing seats are arranged on two opposite sides, which is convenient for installing and adjusting the lower foam roller 20 and the upper foam roller 21, and also convenient for daily maintenance and replacement. The lower foam roller 20 and the upper foam roller 21 are connected to the rotating drive device 3, which is convenient for the operator to flexibly control the foam pressure and foam size according to production needs, thereby improving production efficiency.

[0033] like Figure 7 As shown, one of the vertical side portions 100 of the U-shaped bracket 10 is provided with an escape groove 1001 , and the same end of the upper foam roller 21 and the lower foam roller 20 passes through the escape groove 1001 .

[0034] The avoidance groove 1001 can ensure that the positions of the upper pressure foam roller 21 and the lower pressure foam roller 20 on the U-shaped bracket 10 are fixed. The avoidance groove 1001 can make the connection between the foam roller and the U-shaped bracket tighter, maintaining the stability of the overall structure. At the same time, it can effectively prevent the frictional contact between the upper pressure foam roller 21 and the lower pressure foam roller 20 and the U-shaped bracket 10, reducing the wear caused by long-term friction and extending the service life of the foam press parts.

[0035] like Figure 5-Figure 6 As shown, at least one driving gear 40 of the gear transmission assembly 4 is rotatably connected to the vertical side portion 100 , and mutually meshing transmission gears 41 are respectively provided at the same end of the upper foam pressure roller 21 and the lower foam pressure roller 20 , and the driving gear 40 is connected to the driver 5 .

[0036] The mutual meshing design of the gears can ensure the synchronous operation of the upper foam pressure roller 21 and the lower foam pressure roller 20.

[0037] Two opposite sides of the U-shaped bracket 10 and the frame 1 form two chambers 12 , and the gear transmission assembly 4 is built in one of the chambers 12 .

[0038] Placing the gear transmission assembly 4 in the chamber 12 can effectively isolate and protect the gear transmission assembly 4 from being affected by external impurities such as dust and liquid.

[0039] A plurality of guide shafts 13 are also provided between the opposite sides of the U-shaped bracket 10. Before the U-shaped bracket 10 is formed, guide shaft positioning holes 16 have been formed on the metal plate. After the U-shaped bracket 10 is formed, coaxial guide shaft positioning holes 16 are formed on the opposite sides of the U-shaped bracket 10 in pairs. At this time, both ends of the guide shafts 13 are installed in the corresponding guide shaft positioning holes 16 in the form of rotating bearings or sleeves to achieve mutual parallelism of the plurality of guide shafts 13, ensure the balance of the guide gap, and prevent the guide from deviating and requiring correction.

[0040] The guide shaft 13 is used to guide the movement direction of the finished product so that the finished product can be better collected.

[0041] The structure of the upper foam pressing roller 21 is the same as that of the lower foam pressing roller 20 , and includes a foam pressing shaft 23 formed of a plastic material. A plurality of grooves 230 and a plurality of protrusions 231 are provided on the outer wall of the foam pressing shaft 23 .

[0042] Since the bubble pressing shaft 23 needs to be replaced regularly, the advantage of the above-mentioned plastic material molding is that the cost of plastic materials is lower. At the same time, the bubble pressing shaft 23 molded from plastic materials has higher wear resistance and corrosion resistance. The structural distribution of the grooves 230 and the protrusions 231 can effectively improve the pressure distribution, making the pressure more evenly distributed on the processed products, and reducing product quality problems caused by uneven pressure.

[0043] The bubble pressing shaft 23 is any one of a hollow rotating shaft and a solid shaft.

[0044] In this embodiment, the bubble pressing shaft 23 is a hollow rotating shaft. Compared with a solid shaft, the hollow rotating shaft is lighter, which helps to reduce the load of the entire machine equipment. The hollow rotating shaft consumes relatively less raw materials, which can reduce manufacturing costs.

[0045] A sliding member 110 is provided on the foam roller fixing seat 11 and slides vertically relative to the foam roller fixing seat 11 . Both ends of the upper foam roller 21 are rotationally connected to the sliding member 110 , respectively. A vertical spring 111 is provided between the top of the sliding member 110 and the foam roller fixing seat 11 .

[0046] The setting of the sliding member 110 allows the upper pressure foam roller 21 to slide freely during the pressing process, thereby adapting to molded products of different shapes and sizes and reducing uneven pressure. The setting of the vertical spring 111 can provide stable support and buffering effects, and can better absorb impact and vibration during the pressing process.

[0047] The U-shaped bracket 10 has a drive device accommodating chamber 14 inside, and the rotary drive device 3 is located in the drive device accommodating chamber 14 .

[0048] The rotary drive device 3 is located inside the accommodating chamber 12 , which can effectively prevent external debris, dust, water and other substances from entering and interfering with the normal operation of the rotary drive device 3 , thereby extending the service life of the rotary drive device 3 .

[0049] A through hole 140 is provided at the bottom of the U-shaped bracket 10 to allow the drive device accommodating chamber 14 to communicate with the outside.

[0050] The provision of the through hole 140 can promote air circulation, effectively dissipate the heat generated by the rotary drive device 3, reduce the working temperature of the rotary drive device 3, and improve its working efficiency and stability.

[0051] Embodiment 2

[0052] The structure and principle of this embodiment are basically the same as those of the first embodiment, and the difference lies in that, with respect to the bubble pressing shaft of the first embodiment, this embodiment exemplifies a bubble pressing shaft.

[0053] In this embodiment, the bubble pressing shaft 23 is a solid shaft. The solid shaft has strong integrity, good load-bearing capacity and anti-torsion performance, can withstand large pressure and torque, and is suitable for occasions requiring high-strength support. At the same time, the solid shaft has no hollow structure, is not easy to deform or twist, has good stability, and is conducive to maintaining the stability and balance of the equipment during operation.

[0054] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
