[0001] The utility model relates to the technical field of road construction, in particular to a curb backrest forming machine. Background Technique

[0002] Curb stones are generally the cornerstones that separate the sidewalk from the roadway. During the laying process of existing curb stones, generally, after the curb stones are placed, the back of the curb stones is reinforced with a backrest. A forming machine is required during the production process of the curb stone backrest.

[0003] After the conventional curb stone backrest forming machine forms the curb stone backrest, it mostly adopts the manual processing method to take out the curb stone backrest from the forming mold. Manual mold removal has the problem of low mold removal efficiency, which is time-consuming and laborious, and the production cost is relatively high. Moreover, during mold removal, it is easy to cause uneven forming quality of the curb stone backrest, which is not conducive to the refined management and overall quality control of the factory. Therefore, we propose a curb stone backrest forming machine to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a curb stone backrest forming machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Please refer to Figures 1 to 6 , as an embodiment of the present invention, a curb backrest forming machine includes a frame 1, a mixing bin 2 is fixed on the frame 1, a stirring mechanism for mixing the raw materials of the curb backrest is arranged in the mixing bin 2, a hopper 8 is fixed at the bottom of the mixing bin 2, and a through groove 9 is penetrated through the hopper 8;

[0026] A forming die 10 is rotatably arranged on a frame 1. One end of the forming die 10 is open, and a feed inlet 11 located directly below a feeding hopper 8 is provided at the top of the other end. A cylinder 14 is fixed on the frame 1. Two push rods 15 symmetrically distributed on both sides of the forming die 10 are installed on the output piston rod of the cylinder 14. A sealing plate 16 that is movably clamped inside a through groove 9 and a sliding plate 17 that is slidably clamped on the frame 1 are successively fixed on the push rod 15. An arc-shaped protrusion 18 is fixed on the sliding plate 17.

[0027] A rotating rod 24 is rotatably installed on the frame 1 through a bearing. A baffle 25 located at the open end of the forming die 10 is fixed on the rotating rod 24. The rotating rod 24 and the push rod 15 are connected and cooperated through a linkage structure. When the push rod 15 expands and contracts, it can drive the rotating rod 24 to rotate to drive the baffle 25 to flip.

[0028] In this embodiment, after the raw materials of the curbstone backrest are added into the mixing bin 2, the raw materials are evenly mixed by a stirring mechanism, and the raw materials are conveyed into the forming die 10 through the feeding hopper 8. After the raw materials of the curbstone are added into the forming die 10, the cylinder 14 can be started to push the push rod 15 forward, so as to push the sealing plate 16 to be clamped in the through groove 9 to seal the feeding hopper 8 and stop feeding. After the curbstone is formed, the cylinder 14 continues to push the push rod 15 forward to move the arc-shaped protrusion 18 to the lower part of the forming die 10 to jack up the bottom of one end of the forming die 10, so that the forming die 10 is turned and tilted, and at the same time drives the rotating rod 24 to rotate to make the baffle 25 flip. Thus, after the curbstone backrest is formed in the present invention, the forming die 10 automatically turns and tilts, which can facilitate the formed curbstone backrest to quickly slide out of the forming die 10 under the action of gravity for demoulding, so as to be conveniently taken out quickly.

[0029] As a further scheme of the present invention, a cover plate 3 is hinged to the top of the mixing bin 2, and a feed pipe 4 is fixed on the cover plate 3. The feed pipe 4 is used for feeding materials into the mixing bin 2.

[0030] In this embodiment, the cover plate 3 is flipped to the mixing bin 2 to seal the top of the mixing bin 2, and the feed pipe 4 is used for feeding materials into the mixing bin 2.

[0031] As a further scheme of the present invention, the stirring mechanism includes a motor 5 fixed on the mixing bin 2. The output end of the motor 5 is fixed with a rotating shaft 6 rotatably arranged on the mixing bin 2. A stirring paddle 7 is fixed on the rotating shaft 6 and located inside the mixing bin 2.

[0032] In this embodiment, the motor 5 is started to drive the rotating shaft 6 to rotate, driving the stirring paddle 7 to rotate to mix and stir the raw materials of the curbstone backrest entering the mixing bin 2.

[0033] As a further solution of the present invention, a fixing rod 12 is fixed on the frame 1 , and a sleeve 13 movably sleeved on the fixing rod 12 is fixed to the bottom of one end of the forming mold 10 .

[0034] In this embodiment, the sleeve 13 can rotate on the fixing rod 12 so that the forming mold 10 can be turned around the fixing rod 12 .

[0035] As a further solution of the present invention, a roller 26 is rotatably provided at the bottom of one end of the forming mold 10 close to the arc-shaped protrusion 18 .

[0036] In this embodiment, the roller 26 rolls on the arc-shaped protrusion 18 so that the arc-shaped protrusion 18 can smoothly lift up the bottom of the forming mold 10 when it moves to the bottom of the forming mold 10 .

[0037] As a further solution of the present utility model, the linkage structure includes a movable sleeve 19 rotatably set on the frame 1 and a track groove 20 opened on the push rod 15. The track groove 20 is movably inserted into the movable sleeve 19. The inner wall of the movable sleeve 19 is movably embedded with a ball 21, and the ball 21 can roll along the track where the track groove 20 is located. The track groove 20 consists of a long strip groove and a threaded groove. The movable sleeve 19 and the rotating rod 24 are connected by a gear transmission mechanism.

[0038] In this embodiment, when the push rod 15 is pushed forward, it moves in the movable sleeve 19, thereby rolling along the track in the track groove 20 through the ball 21, driving the movable sleeve 19 to rotate, and then utilizing the transmission connection between the movable sleeve 19 and the rotating rod 24 through the gear transmission mechanism to drive the rotating rod 24 to rotate.

[0039] As a further solution of the present invention, the gear transmission mechanism includes a first bevel gear 22 fixed on the push rod 15 and a second bevel gear 23 fixed on the rotating rod 24 , and the first bevel gear 22 is meshed with the second bevel gear 23 .

[0040] In this embodiment, the rotation of the push rod 15 drives the first bevel gear 22 to rotate, thereby driving the second bevel gear 23 to rotate, thereby driving the rotating rod 24 to flip.

[0041] The working principle of this utility model is as follows: start the cylinder 14 to push the push rod 15 to move forward, thereby pushing the sealing plate 16 to be clamped in the through slot 9 to seal the lower hopper 8. After the curb stone backrest raw materials are added to the mixing bin 2, start the motor 5 to drive the rotating shaft 6 to rotate and drive the stirring paddle 7 to rotate to mix and stir the curb stone backrest raw materials entering the mixing bin 2, and mix the raw materials evenly. After mixing evenly, start the cylinder 14 to push the push rod 15 to move backward, thereby pushing the sealing plate 16 to release the clamping in the through slot 9 and no longer seal the lower hopper 8. The raw materials are transported to the inside of the forming mold 10 through the lower hopper 8 and the feed port 11. After the curb stone raw materials are added to the forming mold 10, the cylinder 14 can be started to push the push rod 15 to move forward, thereby pushing the sealing plate 16 to be clamped in the through slot 9 to seal the lower hopper 8. The sealing is carried out and the material is stopped. After the curb stone is formed, the cylinder 14 is started to continue to push the push rod 15 forward so that the arc-shaped protrusion 18 moves to the bottom of the forming mold 10 to lift the bottom of one end of the forming mold 10, so that the forming mold 10 is flipped and tilted. At the same time, when the push rod 15 is pushed forward, it will move in the movable sleeve 19, so that it can roll along the track where the track groove 20 is located through the ball bearing 21, which can drive the movable sleeve 19 to rotate, and then use the gear transmission mechanism between the movable sleeve 19 and the rotating rod 24 to drive the rotating rod 24 to rotate, so that the baffle 25 is flipped. Therefore, the utility model automatically flips and tilts through the forming mold 10 after the curb stone backrest is formed, which can facilitate the curb stone backrest to quickly slide out of the forming mold 10 under the action of gravity after forming, thereby facilitating quick removal.

[0042] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
