Description

Technical Field

[0001] This invention relates to the field of conveyor belt processing technology, specifically to a conveyor belt forming device. Background Technology

[0002] Currently, there are two main methods for forming conveyor belts: stacking and layering. Conveyor belts with four or more layers are mostly processed using the stacking method. Conveyor belts processed using the stacking method often require pressing equipment to press the multiple layers together to ensure that the conveyor belt can be formed. For example, Chinese patent publication number CN209718427U discloses a fabric core conveyor belt preform forming device, including a base plate. A calendering bracket is symmetrically welded to the top center of the base plate. A lower pressure roller is rotatably connected to the bottom inner side of the calendering bracket. A support plate is fixedly installed at the top of the calendering bracket. Fixing holes are equidistantly opened at the middle of the side of the support plate. A connecting sleeve plate is sleeved to the outer side of the top of the support plate. A fastening knob is fixedly connected to the middle outer side of the connecting sleeve plate. A handle is fixedly installed at the middle top of the connecting sleeve plate by screws. An upper pressure roller is rotatably connected to the middle inner side of the connecting sleeve plate. This solution has a scientific and reasonable structure, is safe and convenient to use. The distance between the upper and lower pressure rollers can be adjusted through the calendering bracket, support plate, fixing holes, connecting sleeve plate, fastening knob, and handle, thereby enabling the upper and lower pressure rollers to perform calendering operations on fabric core conveyor belts of different thicknesses, expanding the application range of the forming equipment.

[0003] The aforementioned patent provides a pressing device capable of adjusting the pressure rollers. The adjustment structure allows for customization of the gap between the pressure rollers to achieve the desired pressing effect. In the laminated conveyor belt production process, the pressing device not only presses the multi-layered structure of the conveyor belt but also removes air between these layers to prevent air pockets from affecting the belt's quality. However, in practice, the pressing device can only press along the direction of the conveyor belt's movement, meaning air inside the belt can only be expelled in that direction. This results in some air being trapped within the multi-layered structure before it can be effectively expelled. Therefore, multiple pressing operations are required to ensure a strong bond between the multi-layered structures and to expel as much air as possible. However, multiple pressing operations complicate the process and reduce production efficiency. Furthermore, the existing pressing device's method of auxiliary air removal along the conveyor belt's movement direction is insufficient to effectively remove air from the multi-layered structure. Summary of the Invention

Each exhaust assembly includes an exhaust roller and an adapter. One end of the exhaust roller is rotatably connected to the adapter, and one end of the adapter is inserted into the guide rod and threadedly connected to the bidirectional screw.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Two pairs of exhaust assemblies are installed in front of the structure where the lower and upper pressure rollers cooperate. These two pairs of exhaust assemblies have a V-shaped design. This type of exhaust assembly can expel air from both sides of the multi-layered structure of the conveyor belt during the pressing process. Expelling air from the multi-layered structure from both sides reduces the air's escape path, allowing for faster and more effective air removal. This method also reduces the number of pressing cycles on the conveyor belt, thereby improving production efficiency.

[0017] 2. Install a limiting roller above the guide roller to prevent the multi-layer structure of the conveyor belt from detaching from the guide roller before it is properly bonded. The height of the limiting roller can be adjusted according to usage requirements, making it convenient to adjust the position of the limiting roller to better process the conveyor belt.

[0018] 3. The limiting roller is fitted with a limiting sleeve, which can limit the conveyor belts of different widths from both sides, so that the auxiliary conveyor belt can pass smoothly when passing through the exhaust mechanism. Moreover, the limiting sleeve of this structure can be flexibly adjusted, which facilitates the use of the limiting sleeve. Attached Figure Description

[0035] like Figure 3 As shown, the bottom of the mounting bracket 21 is equipped with a plug-in rod 211 aligned with the plug-in slot 116. The plug-in rod 211 matches the plug-in slot 116, facilitating the insertion of the mounting bracket 21 and the mounting plate 115 together. The top of the adjusting screw 23 is equipped with a rotating handle 232, which allows for easy rotation of the adjusting screw 23, facilitating adjustment by driving the upper pressure roller 22. Furthermore, the bottom of the adjusting screw 23 is equipped with a connecting shaft 231, which allows for rotatable connection between the bottom of the adjusting screw 23 and the second bearing 118.

[0036] like Figure 4 As shown, the guide rod 3 has a third bearing 31 at both its top and inner bottom ends. The third bearing 31 facilitates the engagement of the bidirectional screw 42, allowing the two ends of the bidirectional screw 42 to be rotatably connected to the guide rod 3. The guide rod 3 also has an adjustment port 32 on its side, which facilitates the engagement of the exhaust assembly 5, allowing the exhaust assembly 5 to move up and down along the adjustment port 32. The bottom end of the guide rod 3 has a bottom shaft 33, which is interference-fitted with the first bearing 113. The engagement of the bottom shaft 33 and the first bearing 113 facilitates the rotatable connection between the bottom end of the guide rod 3 and the base 11.

[0037] like Figure 5As shown, the drive motor 41 has a connecting foot 411 at the top of the guide rod 3, which facilitates the fixing of the drive motor 41 with bolts. The bottom end of the bidirectional screw 42 has two adapter shafts 421, which are interference-fitted with the third bearing 31.

Furthermore, the top of the bidirectional screw 42 has a drive slot 422 that connects to the output end of the drive motor 41, allowing the drive motor 41 to rotate the bidirectional screw 42.

[0038] like Figure 6 As shown, the end of the exhaust roller 51 facing the adapter 52 is provided with a mounting shaft 511, which facilitates the rotatable connection between the exhaust roller 51 and the adapter 52. The adapter 52 is provided with a fourth bearing 521 aligned with the mounting shaft 511, and the mounting shaft 511 and the fourth bearing 521 are rotatably connected. The fourth bearing 521 facilitates the mounting shaft 511 and the rotatable connection between the exhaust roller 51 and the adapter 52. Furthermore, the end of the adapter 52 that inserts into the guide rod 3 has a longitudinally threaded hole 522, which facilitates the mating of the bidirectional screw 42, allowing for a threaded connection between the bidirectional screw 42 and the adapter 52.

[0039] Working principle: After assembling all components of the forming device, rotate the guide rod 3 so that the exhaust rollers 51 on the two guide rods 3 form a V-shape. Then, the multi-layered structure of the conveyor belt requiring air removal is passed over the guide roller 13 and through each pair of exhaust components 5, ensuring that each pair of exhaust components 5 clamps the conveyor belt. Finally, the conveyor belt passes between the upper pressure roller 22 and the lower pressure roller 12 and connects to the external traction and winding equipment. Under the pull of the external traction equipment, the conveyor belt is continuously squeezed and expelled by the four pairs of exhaust rollers 51. The air-expelled conveyor belt structure is then squeezed and bonded together by the upper pressure roller 22 and the lower pressure roller 12 to form the desired shape. Compared with the prior art, this application provides two pairs of exhaust assemblies 5 in front of the structure where the lower pressure roller 12 and the upper pressure roller 22 cooperate. The two pairs of exhaust assemblies 5 are designed in a V-shape. Such exhaust assemblies 5 can discharge air from both sides between the multiple layers of the conveyor belt during the pressing process. The air discharge from both sides can reduce the air discharge path, enabling faster and better effective discharge of air between the multiple layers of the conveyor belt. This method can also reduce the number of pressing operations on the conveyor belt, thereby improving the production efficiency of the conveyor belt.
