[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0028] Embodiment 1

[0029] Reference Figure 1-Figure 4 As shown, the utility model discloses a PCB board roller conveying sleeve 22 structure, including:

[0030] A rolling assembly 1, wherein the rolling assembly 1 comprises a plurality of first rotating shafts 11 and a plurality of second rotating shafts 12, wherein the axial direction of the first rotating shafts 11 is arranged parallel to the axial direction of the second rotating shafts 12, and the second rotating shafts 12 are arranged on top of the first rotating shafts 11;

[0031] A support assembly 2, the support assembly 2 includes a support frame 21 and a sleeve 22, the first rotating shaft 11 and the second rotating shaft 12 are arranged between the support frame 21, and multiple first rotating shafts 11 and multiple second rotating shafts 12 are arranged in an array along the length direction of the support frame 21; the support frame 21 is provided with multiple shaft seats 211 along the length direction, the sleeve 22 is embedded in the shaft seat 211, and both ends of the first rotating shaft 11 and both ends of the second rotating shaft 12 are both inserted into the shaft seat 211, and one end of the sleeve 22 that cooperates with the second rotating shaft 12 is a U-shaped groove 221; buckles 223 are provided on both sides of the U-shaped groove 221 port, and a boss 212 is provided on the shaft seat 211, and the buckle 223 is clamped with the boss 212.

[0032] It can be imagined that a plurality of first rotating shafts 11 and a plurality of second rotating shafts 12 are arranged between the support frame 21, wherein the first rotating shaft 11 is arranged at the bottom, and the second rotating shaft 12 is arranged at the top of the first rotating shaft 11, and the support frame 21 is provided with a sleeve 22 at the position where the first rotating shaft 11 and the second rotating shaft 12 are matched, and both ends of the first rotating shaft 11 and the second rotating shaft 12 are inserted into the sleeve 22. In the utility model, one end of the sleeve 22 that matches the second rotating shaft 12 is an open structure, that is, a U-shaped groove 221 is provided on the sleeve 22, and when the product passes between the first rotating shaft 11 and the second rotating shaft 12, the second rotating shaft 12 will be lifted. The entire sleeve 22 is embedded in the shaft seat 211 during the assembly process. Since the end of the sleeve 22 is a U-shaped groove 221 structure, in order to avoid the contraction of the end of the U-shaped groove 221 during use, buckles 223 are provided on both sides of one end of the entire sleeve 22 close to the U-shaped groove 221, and a boss 212 cooperating with the buckle 223 is provided on the shaft seat 211.

[0033] In the utility model, the buckles 223 on both sides of the shaft sleeve 22 are engaged with the bosses 212 on the shaft seat 211 to limit the port of the U-shaped groove 221 of the shaft sleeve 22, thereby avoiding the second rotating shaft 12 from being stuck during the lifting process due to shrinkage during use, thereby ensuring the normal operation of the entire equipment.

[0034] Furthermore, the shaft sleeve 22 is provided with a shaft hole 222 which cooperates with the first rotating shaft 11 .

[0035] Specifically, the first rotating shaft 11 is arranged at the bottom of the second rotating shaft 12 and mainly plays a supporting role. Therefore, during the assembly process, an axial hole 222 is opened on the sleeve 22, and the two ends of the first rotating shaft 11 are inserted into the axial hole 222 to realize the self-rotation of the first rotating shaft 11.

[0036] Furthermore, the rolling assembly 1 further comprises a first pressure roller 13 and a second pressure roller 14 , wherein the pressure roller is sleeved on the outer side of the first rotating shaft 11 , and the second pressure roller 14 is sleeved on the outer side of the second rotating shaft 12 , and the first pressure roller 13 and the second pressure roller 14 are in contact with each other.

[0037] Specifically, the first pressing roller 13 is sleeved on the outside of the first rotating shaft 11 and the two are fixedly connected, and the second pressing roller 14 is sleeved on the outside of the second rotating shaft 12 and fixedly connected to ensure synchronous rotation during use. In the utility model, the pressing roller is added to increase the diameter of the second rotating shaft 12. When the product passes, the second pressing roller 14 is lifted up, and the rotating shaft is lifted up in the U-shaped groove 221. The two end surfaces of the second pressing roller 14 can still block the U-shaped groove 221 to prevent the leakage of the soaking liquid 4.

[0038] Secondly, in the present invention, the first pressing roller 13 and the second pressing roller 14 are both integrally formed and are integrally sleeved on the outside of the first rotating shaft 11 and the second rotating shaft 12. The first pressing roller 13 and the second pressing roller 14 are both solid rollers. On the one hand, it is ensured that the second pressing roller 14 has sufficient gravity, and the product can fall back quickly after passing through, reducing the leakage of the soaking liquid 4; on the other hand, the first pressing roller 13 needs to have sufficient strength to support it.

[0039] Furthermore, the first pressing roller 13, the second pressing roller 14, the support frame 21 and the shaft sleeve 22 are all made of PP material.

[0040] Specifically, during actual use, the entire rolling assembly 1 needs to be immersed in the soaking liquid 4 to process the products passing through. The soaking liquid 4 contains a variety of chemical components, which will react with the metal material and affect normal use. Therefore, the materials of the first pressure roller 13, the second pressure roller 14, the support frame 21 and the sleeve 22 in the utility model are all PP materials, which have good corrosion resistance, and the density and hardness meet the use conditions.

[0041] Furthermore, the material of the first rotating shaft 11 and the second rotating shaft 12 is SUS316, and the outer sides of the first rotating shaft 11 and the second rotating shaft 12 are coated with a corrosion-resistant layer, and the material of the corrosion-resistant layer is HCPP plastic.

[0042] Specifically, in the present invention, the axis of the first rotating shaft 11 and the second rotating shaft 12 is made of SUS316 material, which has high strength. At the same time, in order to avoid the influence of chemical solutions, a corrosion-resistant layer is coated on the outside of the axis. Preferably, the corrosion-resistant layer material is HCPP plastic.

[0043] Furthermore, the width of the U-shaped groove 221 is equal to the diameter of the second rotating shaft 12 .

[0044] Furthermore, a first gear 15 is sleeved on one end of the first rotating shaft 11 , and a second gear 16 is sleeved on one end of the second rotating shaft 12 , and the first gear 15 and the second gear 16 are meshed with each other.

[0045] Specifically, the first gear 15 is sleeved on the end of the first rotating shaft 11, and the second gear 16 is sleeved on the end of the second rotating shaft 12. The first gear 15 and the second gear 16 are meshed, and rotating the first gear 15 drives the second gear 16 to rotate synchronously, thereby realizing the synchronous rotation of the first rotating shaft 11 and the second rotating shaft 12.

[0046] Embodiment 2

[0047] Reference Figure 5As shown, a wet process equipment includes the PCB board roller conveying sleeve 22 structure described in Example 1, and also includes an immersion tank 3, and the immersion tank 3 is arranged at the bottom of the rolling component 1.

[0048] Specifically, the soaking tank 3 is arranged at the bottom of the entire rolling assembly 1, and is used to clean the products passing through; as a preferred solution of the utility model, the soaking tank 3 is provided with a soaking liquid 4, and the rolling assembly 1 is immersed in the soaking liquid 4. The height of the soaking liquid 4 is higher than the height of the joint between the first pressing roller 13 and the second pressing roller 14, so as to ensure that the products are completely immersed in the soaking liquid 4.

[0049] In summary, the utility model introduces a PCB board roller conveyor sleeve 22 structure and wet process equipment, by which the buckles 223 on both sides of the sleeve 22 are engaged with the bosses 212 on the shaft seat 211, and the U-shaped groove 221 port of the sleeve 22 is restricted to avoid the second rotating shaft 12 from being stuck during the lifting process due to shrinkage during use, thereby ensuring the normal operation of the entire equipment.
