Description

Technical Field

[0001] This utility model relates to the field of curtain slat forming technology, and in particular to a roller shutter door curtain slat forming machine. Background Technology

[0002] In the production process of roller shutter doors, cold bending forming machines are used to continuously bend the roller shutter door blades laterally to form a specific cross-section profile. The front end of the cold bending forming machine is generally equipped with a feeding device. The feeding device is generally only equipped with a guide groove, without other auxiliary guiding components. Long-term use leads to severe wear of the guide groove, which affects the stability of the feeding.

[0003] The feeding device of a cold bending forming machine disclosed in CN210208371U includes a support frame. One end of the support frame is equipped with a pressure roller frame, and one side of the pressure roller frame is equipped with a front frame. The other end of the support frame is fixedly connected to the cold bending forming machine. The support frame is equipped with two fixed plates arranged side by side, with a gap between the two fixed plates. Two guide plates are provided on the two fixed plates. The bearing and guide groove of this utility model reduce the feeding resistance when the roller shutter door blades pass through the guide grooves, thereby reducing the friction on the roller shutter door blades and increasing the wear resistance of the guide grooves. In addition, the distance between the two guide plates can be adjusted according to the width of the roller shutter door blades, so that the feeding device can be adapted to the feeding of roller shutter door blades of different sizes.

[0004] The above-mentioned device can adjust the distance between the two guide plates according to the width of the roller shutter door blades, but when adjusting, it is necessary to turn multiple adjusting screws to adjust the two guide plates separately, which is quite troublesome.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figures 1-4 A roller shutter slat forming machine includes a forming machine body 1 and a guide shaft 2. A first lead screw 3 is rotatably connected to the inner wall of the forming machine body 1, and a second lead screw 4 is fixedly connected to one end of the first lead screw 3. A housing 5 is fixedly connected to one side wall of the forming machine body 1, and a drive connector is provided inside the housing 5. Guide components are threaded on the outer walls of both the first lead screw 3 and the second lead screw 4.

[0023] As can be seen from the above structure, by setting the first lead screw 3, the second lead screw 4 and the drive connector to work together, the first lead screw 3 and the second lead screw 4 can be rotated simultaneously through the drive connector during use, so that the first lead screw 3 and the second lead screw 4 drive the guide assembly to move in the same or opposite directions at the same time, thus making it convenient and quick to adjust the guide width.

[0024] Furthermore, the drive connector includes a rotating shaft 6 rotatably connected to the inner wall of the housing 5, and a worm gear 7 is fixedly sleeved on the outer wall of the rotating shaft 6. A worm wheel 8 is meshed on one side wall of the worm gear 7. One end of the second lead screw 4 passes through the molding machine body 1 and extends into the housing 5. The second lead screw 4 located inside the housing 5 is fixedly connected to the worm wheel 8. A first bevel gear 9 is fixedly sleeved on the outer wall of the rotating shaft 6, and a second bevel gear 10 is meshed on one side wall of the first bevel gear 9. A first control rod 11 is fixedly connected to one side wall of the second bevel gear 10, and one end of the first control rod 11 passes through the housing 5 and extends into the housing 5. Extending to the outside of the housing 5, a guide assembly consisting of a worm gear 8 and a worm 7 is provided. During adjustment, the first control lever 11 can be rotated, causing the first control lever 11 to drive the second bevel gear 10 to rotate. The rotating second bevel gear 10 drives the first bevel gear 9 to rotate, and the rotating first bevel gear 9 drives the rotating shaft 6 and the worm 7 to rotate. The rotating worm 7 can then drive the worm gear 8, the second lead screw 4, and the first lead screw 3 to rotate. Due to the self-locking property of the worm gear 8 and the worm 7, the guide assembly will not move arbitrarily without the need for fixing during use, thus facilitating the use of the device.

[0025] Furthermore, the guide assembly includes a threaded sleeve 12 that is threaded onto the outer walls of the first lead screw 3 and the second lead screw 4 respectively. A guide groove 13 is provided on the upper surface of the forming machine body 1, and one end of the threaded sleeve 12 passes through the guide groove 13 and extends to the outside of the guide groove 13. A guide fixing seat 14 is fixedly connected to the outer wall of the threaded sleeve 12 located outside the guide groove 13, and the guide shaft 2 is rotatably connected to the fixing seat 14. By setting the threaded sleeve 12 and the guide fixing seat 14 to work together, the guide fixing seat 14 can support the guide shaft 2 during use, so that the guide shaft 2 can rotate and guide during use, thereby reducing friction on the roller shutter door blades.

[0026] Furthermore, a limiting slide rod 15 is fixedly connected to the inner wall of the molding machine body 1, and the limiting slide rod 15 passes through the threaded sleeve 12; by setting the limiting slide rod 15, the threaded sleeve 12 can be limited, increasing the stability of the threaded sleeve 12 when it moves.

[0027] Furthermore, a second control lever 16 is provided inside the housing 5, and a large gear 17 is fixedly sleeved on the outer wall of the second control lever 16. A small gear 18 is fixedly sleeved on the outer wall of the first control lever 11, and the small gear 18 meshes with the large gear 17. One end of the second control lever 16 passes through the housing 5 and extends to the outside of the housing 5. By setting the second control lever 16, the large gear 17 and the small gear 18 to work together, during adjustment, the second control lever 16 can be rotated for quick adjustment. During use, rotating the second control lever 16 can drive the large gear 17. Since the outer diameter of the large gear 17 is large, the large gear 17 can drive the small gear 18 and the first control lever 11 to rotate quickly.

[0028] Furthermore, the first lead screw 3 and the second lead screw 4 have opposite thread directions; by setting the first lead screw 3 and the second lead screw 4 with opposite thread directions, when the second lead screw 4 is rotated, the first lead screw 3 and the second lead screw 4 can move in the same or opposite directions with the guide assembly.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
