[0004] The aforementioned prior art can adjust the distance between the upper and lower rollers. However, during use, although the distance can be adjusted, the rollers on both sides lack external driving force, resulting in poor pressing quality, affecting product quality, and making it inconvenient to use. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a filter cloth production pressing mechanism that solves the problem that existing devices cannot rotate the upper and lower pressure rollers with external power after the spacing is adjusted, thus affecting the pressing quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter cloth production pressing mechanism, comprising a base, a pair of support plates on the upper wall of the base, a lower roller shaft rotatably mounted between the pair of support plates, an upper roller shaft above the lower roller shaft, and pressure rollers mounted on both the lower and upper roller shafts. A sliding groove is formed on one side of the support plate, and a sliding seat that can slide up and down is provided within the sliding groove. A through groove is formed on the other side of the support plate, and a sliding box that can slide up and down is provided within the through groove. One end of the upper roller shaft is rotatably connected to the sliding seat, and the other end extends into... The slide box contains a second transmission gear. A main shaft is rotatably mounted on the upper wall of the base, located on one side of the support plate. A first drive gear is mounted on the main shaft. A first transmission gear meshing with the first drive gear is mounted on one end of the lower roller shaft. A slide cavity is provided inside the upper end of the main shaft. A transmission shaft is coaxially arranged in the slide cavity. The transmission shaft can rotate synchronously with the main shaft and can slide up and down in the slide cavity. The upper end of the transmission shaft extends into the slide box and is equipped with a second drive gear meshing with the second transmission gear. The base is provided with a drive assembly and an adjustment assembly.

[0008] Preferably, the adjustment assembly includes an electric actuator disposed on the upper wall of the base, a connecting frame is provided on the side wall of the slide box, and the telescopic end of the electric actuator is fixedly connected to the connecting frame.

[0009] Preferably, guide grooves are provided on both sides of the through groove, and a pair of guide blocks are provided on the outer wall of the slide box that are slidably connected to the guide grooves.

[0010] Preferably, the inner walls on both sides of the sliding cavity are provided with a pair of limiting guide grooves, and the side wall of the transmission shaft is provided with a pair of limiting guide blocks that are slidably connected to the limiting guide grooves.

[0011] Preferably, both the upper roller shaft and the drive shaft are connected to the slide box via bearings.

[0012] Beneficial effects

[0013] This utility model provides a pressing mechanism for filter cloth production, which has the following beneficial effects:

[0014] The telescopic end of the electric push rod in the adjustment assembly is fixedly connected to the connecting frame of the slide box. By controlling the extension and retraction of the electric push rod, the up and down position of the slide box can be precisely adjusted, thereby driving the upper roller to move up and down, realizing the adjustment of the distance between the upper roller and the lower roller, ensuring the uniformity of the pressing effect, meeting the needs of filter cloths of different thicknesses, and improving the quality and performance of the filter cloth.

[0015] In the drive assembly, the motor drives the main gear to rotate. The main gear meshes with the auxiliary gear at the bottom of the main shaft, causing the main shaft to rotate. The main shaft then meshes with the first transmission gear of the lower roller shaft through the first drive gear, transmitting power to the lower roller shaft. Simultaneously, the transmission shaft inside the main shaft meshes with the second transmission gear of the upper roller shaft through the second drive gear, transmitting power to the upper roller shaft. This transmission method ensures that the upper and lower roller shafts can still rotate relative to each other after the spacing is adjusted, ensuring the stability of power transmission, improving the pressing effect, and guaranteeing production quality.

[0016] The guide grooves on both sides of the through groove cooperate with the guide blocks on the outer wall of the slide box to provide good guidance for the slide box to slide up and down, ensuring the smoothness and accuracy of the slide box movement. The limiting guide grooves on both sides of the slide cavity cooperate with the limiting guide blocks on the side wall of the transmission shaft to limit the range of movement of the transmission shaft in the slide cavity, ensuring the synchronous rotation of the transmission shaft and the main shaft, and also adapting to the change of the position of the upper roller shaft, thus improving the stability and reliability of the entire mechanism.

A drive assembly and an adjustment assembly are provided on the base 1.

[0022] By adopting the above technical solution, during the filter cloth pressing process, the drive component drives the main shaft 10 to rotate, and the main shaft 10 drives the upper roller shaft 4 and the lower roller shaft 3 to rotate through gear transmission, ensuring the pressing quality. The adjustment component can adjust the position of the upper roller shaft 4 to adjust the distance and pressure between the upper roller shaft 4 and the lower roller shaft 3, realizing the rotation and pressure adjustment functions of the upper roller shaft 4 and the lower roller shaft 3, providing a foundation for efficient and high-quality pressing of filter cloth.

[0023] In this embodiment, the driving assembly includes a motor 16 disposed on the upper wall of the base 1, a main gear 17 is mounted on the driving end of the motor 16, and a secondary gear 18 that meshes with the main gear 17 is provided at the bottom of the main shaft 10.

[0024] By adopting the above technical solution, the motor 16 is started, and the motor 16 drives the main gear 17 to rotate. The main gear 17 meshes with the auxiliary gear 18 at the bottom of the main shaft 10, driving the main shaft 10 to rotate. This realizes the transmission of power from the motor 16 to the main shaft 10, providing a power source for the rotation of the upper roller shaft 4 and the lower roller shaft 3, and ensuring the normal operation of the pressing mechanism.

[0025] In this embodiment, the adjustment component includes an electric push rod 19 disposed on the upper wall of the base 1, and a connecting frame 20 is provided on the side wall of the slide box 8. The telescopic end of the electric push rod 19 is fixedly connected to the connecting frame 20.

[0026] By adopting the above technical solution, according to the specifications of the filter cloth to be pressed, the electric push rod 19 is started, and the telescopic end of the electric push rod 19 pushes the connecting frame 20, so that the slide box 8 slides up and down in the through groove 7, driving the upper roller shaft 4 to move up and down, adjusting the distance between the upper roller shaft 4 and the lower roller shaft 3, meeting the pressing requirements of filter cloths of different specifications, and improving the uniformity of the pressing effect and product quality.

[0032] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0033] Example: According to the specifications of the filter cloth to be pressed, the sliding box 8 is pushed up and down by the electric push rod 19 of the adjustment component, which in turn causes the upper roller shaft 4 to drive the pressure roller to move synchronously. The position of the upper roller shaft 4 is adjusted so that the distance between the upper and lower pressure rollers reaches a suitable value. The motor 16 is started, and the motor 16 drives the main gear 17 to rotate. The main gear 17 drives the auxiliary gear 18 at the bottom of the main shaft 10 to rotate, so that the main shaft 10 rotates.

Meanwhile, the transmission shaft 14 inside the main shaft 10 rotates synchronously with the main shaft 10 in the sliding cavity 13. The transmission shaft 14 meshes with the second transmission gear 9 of the upper roller shaft 4 through the second drive gear 15, driving the upper roller shaft 4 to rotate, realizing the relative rotation of the upper roller shaft 4 and the lower roller shaft 3. The filter cloth to be pressed is placed between the upper roller shaft 4 and the lower roller shaft 3. As the upper roller shaft 4 and the lower roller shaft 3 rotate, the filter cloth is pressed. The position of the upper roller shaft 4 can be finely adjusted by adjusting the electric push rod 19 of the adjustment component according to the actual situation to ensure the uniformity of the pressing effect.
