Description

Technical Field

[0001] This utility model belongs to the technical field of tobacco factory equipment, specifically relating to a roller shutter door with a slow-closing function. Background Technology

[0002] The factory buildings of cigarette factories typically use roller shutters. A roller shutter is a vertical door with multiple articulated door panels linked together, which are opened and closed by rotating an upper roller. Existing roller shutters have a simple structure, and there is a risk of them falling during the raising and lowering process, posing a safety hazard. Therefore, roller shutters with a slow-closing function are required.

[0003] The prior art, Chinese utility model patent with publication number CN211058672U, discloses a roller shutter door with a slow-closing function. The roller shutter door achieves a slow-closing effect by using elastic ropes in conjunction with a clamping steel column and other structures. However, the slow-closing effect achieved by the above structure alone is not significant enough, and the elastic rope is prone to fatigue due to frequent use, which may lead to breakage.

[0004] Therefore, how to design a roller shutter door with a slow-closing function to improve the slow-closing effect has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a roller shutter door with a slow-closing function to solve the above-mentioned technical problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A roller shutter door with a slow-closing function includes a winding assembly and a slow-closing assembly. The winding assembly includes a winding shaft with rotating shafts fixedly connected to both ends. A first bevel gear is detachably connected to the side surface of one of the rotating shafts. A servo motor is installed at one end of the winding shaft, and a second bevel gear is connected to the output end of the servo motor. The first and second bevel gears are meshed together. The slow-closing assembly includes two side plates with toothed grooves on their opposite surfaces. A roller shutter door body is connected between the two side plates. A horizontal bar is fixedly connected to the lower end of the roller shutter door body. Slow-closing gears are rotatably connected to both ends of the horizontal bar. Octagonal holes are provided at both ends of the horizontal bar. Octagonal shafts are fixedly connected to both sides of the slow-closing gears and inserted into the octagonal holes. Reinforcing plates are detachably installed at the lower ends of the two side plates, and the slow-closing gears are meshed within the toothed grooves.

[0008] Preferably, both ends of the take-up shaft are equipped with fixing plates, the rotating shaft is rotatably connected inside the fixing plates, and several limiting strips are fixedly connected to the side surface of the take-up shaft.

[0009] Preferably, both ends of the rotating shaft are fixedly connected to mounting heads, and bearings are installed inside the mounting heads, with the rotating shaft rotatably connected inside the bearings.

[0010] Preferably, the side surfaces of the two fixing plates are detachably fitted with mounting shells, and the lower end of the mounting shells is provided with a strip groove, and the roller shutter door body is installed inside the strip groove.

[0011] Preferably, the upper end of the horizontal bar has two insertion slots, and the two side plates are inserted into the insertion slots. The lower end of the two side plates has insertion holes, and insertion rods are inserted into the insertion holes.

[0012] Preferably, two mounting plates are fixedly connected to one side of the roller shutter door body, and a limiting groove is opened in the middle of the two mounting plates. The rotating shaft and several limiting strips on its side surface are inserted into the limiting groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model discloses a roller shutter door with a slow-closing function. In use, the servo motor first drives the second bevel gear to rotate clockwise, which in turn drives the first bevel gear and its surface shaft to rotate counterclockwise. This causes the roller shutter door body to rotate counterclockwise, allowing it to unfold for use. During this process, the slow-closing gear descends slowly along the tooth groove. As the slow-closing gear rotates, it controls the octagonal shaft to rotate along the octagonal hole, thus providing resistance to enhance the slow-closing effect. The slow-closing gear structure also provides slow-closing stability. When retracting, the servo motor drives the second bevel gear to rotate counterclockwise, which in turn drives the first bevel gear and shaft to rotate clockwise, thus retracting the roller shutter door body onto the retractor shaft side surface. Therefore, this utility model can significantly improve the slow-closing effect of the roller shutter door and eliminates concerns about fatigue breakage of the elastic rope due to frequent use, as seen in existing technologies, thus significantly improving the safety of the roller shutter door.

[0024] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0025] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0026] like Figures 1 to 6 As shown, this utility model embodiment provides a roller shutter door with a slow-closing function, which includes a winding assembly 100 and a slow-closing assembly 200. The winding assembly 100 includes a winding shaft 101, and both ends of the winding shaft 101 are fixedly connected to a rotating shaft 102. A first bevel gear 103 is detachably connected to the side surface of one of the rotating shafts 102. A servo motor 104 is installed at one end of the winding shaft 101, and the output end of the servo motor 104 is connected to a second bevel gear 105. The first bevel gear 103 and the second bevel gear 105 are meshed together. The slow-closing assembly 200 includes two side plates 2 01. The two side plates 201 are provided with toothed grooves 202 on their opposite surfaces. The roller shutter door body 203 is connected between the two side plates 201. A horizontal bar 204 is fixedly connected to the lower end of the roller shutter door body 203. Both ends of the horizontal bar 204 are rotatably connected with a slow-descent gear 205. Both ends of the horizontal bar 204 are provided with octagonal holes 206. Octagonal shafts 207 are fixedly connected to both sides of the slow-descent gear 205. The octagonal shafts 207 are inserted into the octagonal holes 206. A reinforcing plate 208 is detachably installed at the lower end of the two side plates 201. The slow-descent gear 205 is meshed in the toothed grooves 202.

[0027] The roller shutter door with a slow-closing function provided in this embodiment of the utility model, when in use, firstly, the servo motor 104 is started, driving the second bevel gear 105 to rotate clockwise, which in turn drives the first bevel gear and its surface shaft to rotate counterclockwise, thereby rotating the roller shutter door body counterclockwise and unfolding it for use. During this process, the slow-closing gear descends slowly along the tooth groove. As the slow-closing gear rotates, it controls the octagonal shaft 207 to rotate along the octagonal hole 206, thereby providing resistance to enhance the slow-closing effect, and the slow-closing gear structure provides slow-closing stability. When rolling up, starting the servo motor and driving the second bevel gear 105 to rotate counterclockwise will drive the first bevel gear and the shaft to rotate clockwise, thereby rolling up the roller shutter door body onto the side surface of the roll-up shaft. It can be seen that this utility model can effectively improve the slow-closing effect of the roller shutter door, and there is no need to worry about the fatigue breakage phenomenon caused by frequent use of elastic ropes in the prior art, which can significantly improve the safety of using the roller shutter door.

[0028] Furthermore, fixing plates 111 are installed at both ends of the winding shaft 101, and the rotating shaft 102 is rotatably connected inside the fixing plates 111. Several limiting strips 112 are fixedly connected to the side surface of the winding shaft 101. With this design, the fixing plates 111 can improve the installation stability between the winding shaft 101 and the doorway wall, and the limiting strips 112 facilitate the limiting installation of the mounting plate 221 and the winding shaft 101.

[0029] Specifically, mounting heads 121 are fixedly connected to both ends of the rotating shaft 102. Bearings 122 are installed inside the mounting heads 121, and the rotating shaft 102 is rotatably connected inside the bearings 122. With this design, the bearings 122 and the rotating shaft 102 are rotatably connected, which reduces the friction when the winding shaft 101 rotates, thereby improving the smoothness of the extension and retraction of the roller shutter door body 203.

[0030] Preferably, mounting shells 131 are detachably mounted on the side surfaces of the two fixing plates 111. A strip groove 132 is formed at the lower end of the mounting shell 131, and the roller shutter body 203 is installed inside the strip groove 132. This design allows the mounting shell 131 and the fixing plates 111 to connect and protect the winding shaft 101, thus improving the protection of the roller shutter body 203.

[0031] Furthermore, the upper end of the horizontal bar 204 has two insertion slots 211, and both side plates 201 are inserted into the insertion slots 211. The lower end of both side plates 201 has insertion holes 212, and insertion rods 213 are inserted into the insertion holes 212. With this design, since the insertion rods 213 are inserted into the insertion slots 211, the ease of disassembly and replacement between the side plates 201 and the reinforcing plate 208 can be improved.

[0032] Specifically, two mounting plates 221 are fixedly connected to one side of the roller shutter body 203. A limiting groove 222 is formed in the middle of the two mounting plates 221, and several limiting strips 112 on the rotating shaft 102 and its side surface are inserted into the limiting groove 222. This design, by engaging the limiting strips 112 within the limiting groove 222, improves the stability of the rotating shaft 102 when it rotates with the winding shaft 101.

[0033] In one specific embodiment, the roller shutter body 203 can be made of cast aluminum. Because a cast aluminum roller shutter body 203 can reduce its weight while maintaining its strength, it can improve the safety and ease of installation when the roller shutter is lowered.

[0034] This invention utilizes a rewinding assembly 100 in conjunction with a slow-descent assembly 200, which not only improves the lifting stability of the roller shutter body 203 but also significantly enhances its slow-descent stability, thereby improving the safety of the roller shutter. Furthermore, the cooperation of these components facilitates disassembly of the roller shutter, increasing the ease of component replacement and reducing maintenance time. When disassembling the roller shutter, first remove the mounting shell, then remove the connecting rod from the connecting hole to disassemble the side plate and reinforcing plate. Finally, pull the rotating shaft out of the mounting plate to disassemble the roller shutter body. Compared to existing roller shutter structures, this invention, through the cooperation of these structures, facilitates the disassembly of each component, effectively improving the convenience of assembly and disassembly.

[0035] In controlling the descent of the roller shutter door, this invention only requires activating the servo motor to rotate the second bevel gear, which in turn rotates the first bevel gear and its surface shaft. This causes the mounting plate and the roller shutter door body to rotate counterclockwise, allowing the roller shutter door, rolled up on the side surface of the take-up shaft, to unfold and descend smoothly. During this process, the slow-descent gear meshes along the tooth grooves, and as the slow-descent gear rotates, the octagonal shaft rotates along the octagonal hole, thus providing resistance to enhance the slow-descent effect. At the same time, the slow-descent gear structure provides slow-descent stability. During retraction, controlling the shaft to rotate clockwise will roll the roller shutter door body onto the side surface of the take-up shaft. Compared with existing roller shutter doors, this invention, through the cooperation of the above structures, not only achieves a slow-descent effect but also improves stability and enhances the safety of using the roller shutter door.

[0036] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
