Description

Technical Field

[0001] The invention relates to the technical field of prefabricated component production, in particular to a prefabricated component forming machine. Background Art

[0002] Prefabricated components refer to steel, wood or concrete components that are prefabricated in factories or on-site according to design specifications. Among them, prefabricated concrete components are building components that are prefabricated in factories using concrete as the basic material. Prefabricated concrete components have advantages not only in terms of functionality and safety, but also in terms of economy and creating a comfortable environment and saving resources; they include prefabricated building components such as walls, beams, slabs, columns, pipes and manhole covers; however, existing prefabricated component forming machines have the following problems:

[0003] 1. In the process of prefabricated component forming, the existing prefabricated component forming machine generally first uses manual labor or concrete trucks to pour raw materials into the mold, and then uses manual shovels to evenly distribute the concrete raw materials in the mold to form prefabricated components. The distribution is uneven and time-consuming and labor-intensive, the quality of the prefabricated components is uneven, and the production efficiency is low;

[0004] 2. During the demoulding process of the prefabricated component, the mold needs to be turned over to make the cavity opening face downward, and then the prefabricated component needs to be separated from the mold by repeatedly knocking the side wall of the mold, or the side panels of the mold need to be removed one by one to complete the demoulding. The demoulding process is cumbersome, time-consuming and labor-intensive.

[0005] 3. When the mold has two stations during the process of forming and demolding the prefabricated component, the first station is that the mold cavity opening faces upward and receives the raw material to form the prefabricated component, and the second station is that the mold cavity opening faces downward and demolds the prefabricated component from the mold; however, when the mold is switched between the first station and the second station, it is generally turned over manually, which is time-consuming, labor-intensive and inefficient; or other turning mechanical equipment is used to turn the mold, wherein each time the turning mechanical equipment turns the mold, it needs to align and cooperate with the mold to accurately turn the mold, and the turning efficiency is low.

[0006] 4. After the mold receives the concrete raw materials, it needs to be moved to the demoulding position of the prefabricated component. Generally, the mold is moved up and down to a position close to the ground for demoulding; however, when the concrete raw materials are not completely solidified and fixed, moving the mold up and down may cause the molding mold to tilt, and then the surface of the prefabricated component will tilt, which will affect the molding quality of the prefabricated component.

[0007] 5. In order to enhance the structural strength of precast concrete components, a steel bar structure is generally arranged in the mold before the precast concrete components are formed, and then concrete is poured to form the precast concrete components with the steel bar structure. However, after the steel bar structure is placed in the mold, the steel bar structure cannot be fixed. When pouring concrete, it will be displaced by the impact of the concrete and cannot be fixed in the middle of the mold. The steel bar structure cannot be located in the middle of the precast concrete component, so that the overall structural strength of the precast concrete component is unbalanced and the structural strength is weakened. Moreover, the steel bar structure will sink to the bottom of the mold so that the steel bar structure may be exposed on the bottom surface of the precast concrete component, and the exposed steel bar affects the flatness of the bottom surface of the precast concrete component, affecting the later assembly and use.

[0008] In view of this, the inventor has made in-depth considerations and actively researched, improved and trial-made the present invention to address the many deficiencies and inconveniences caused by the imperfect structural design of the above-mentioned prefabricated component forming machine, and has developed and designed the present invention.

[0077] In order to further explain the technical solution of the present invention, the present invention is described in detail below through specific embodiments.

[0078] See also Figures 1 to 11The present invention discloses a prefabricated component forming machine, comprising a material distributing mechanism 1 and a forming mold 2 arranged on a frame 100; the material distributing mechanism 1 comprises a material distributing vehicle 11 carrying raw materials, and a material distributing moving mechanism 12 driving the material distributing vehicle 11 to move to the top of the forming mold 2 for distributing materials; the material distributing moving mechanism 12 comprises a material distributing synchronous cross bar 121 and material distributing moving groups symmetrically arranged at both ends of the material distributing synchronous cross bar 121, and the two ends of the material distributing synchronous cross bar 121 are pivotally connected to the frame 100 and are located obliquely above the material distributing vehicle 11; each group of material distributing moving groups comprises a material distributing linkage rod 122, a material distributing push rod 123 and a material distributing cylinder 124, and the material distributing linkage rod 122 is arranged on the material distributing synchronous cross bar 121 end, and has a first force arm 1221 and a second force arm 1222 distributed on both sides of the material distribution synchronization cross bar 121; one end of the material distribution push rod 123 is connected to the material distribution vehicle 11, and the other end is connected to the end of the second force arm 1222; the piston seat of the material distribution cylinder 124 is fixed on the frame 100, and the piston rod of the material distribution cylinder 124 is connected to the end of the first force arm 1221; the forming mold 2 has a cavity 20 for forming a prefabricated component, and the cavity 20 is surrounded by a bottom plate 21, two end plates 22 and two side plates 23; the bottom plate 21 is provided with side plate cylinders 24 that respectively push the two side plates 23 against or away from the two sides of the bottom plate 21, and a vibration motor 25 is provided below the bottom plate 21.

[0079] When the prefabricated component forming machine of the present invention is working, first, the raw materials of the prefabricated components are loaded into the material distributing vehicle 11, the piston rod of the material distributing cylinder 124 retracts to pull the first force arm 1221 to rotate backward with the material distributing synchronous cross bar 121 as the axis, and the second force arm 1222 rotates forward with the material distributing synchronous cross bar 121 as the axis, thereby pushing the material distributing push rod 123 to push the material distributing vehicle 11 forward to the top of the forming mold 2 and distributing the material; when the material distributing is completed, the material distributing mechanism 1 needs to return to the material receiving position after unloading is completed, and the piston rod of the material distributing cylinder 124 pushes out to push the first force arm 1221 to rotate forward with the material distributing synchronous cross bar 121 as the axis. The step cross bar 121 rotates forwardly with the axis, and the second force arm 1222 rotates backward with the material distribution synchronous cross bar 121 as the axis, thereby driving the material distribution push rod 123 to pull the material distribution vehicle 11 to move backward to the material receiving position; and the forming mold 2 is kept for a period of time to allow the raw material to solidify and fix, and then when the prefabricated component is demoulded, the side plate cylinder 24 is driven to push the two side plates 23 away from the bottom plate 21, so that the two sides of the prefabricated component are separated from the restriction of the side plates 23 and are only restricted by the end plates 22 at the other two ends. The forming mold 2 is in an open state, and the prefabricated component can be demoulded from the forming mold 2 conveniently and quickly. The structure is simple, time-saving and labor-saving, and the demoulding efficiency can be improved; the vibration motor 25 can vibrate the raw material and evenly distribute it in the forming mold 2 when the material distributing mechanism 1 is distributing the material, and the vibration motor 25 can vibrate the forming mold 2 during demoulding to facilitate the demoulding of the prefabricated component; the material distributing moving group can save effort to push the raw material to the top of the forming mold 2 for distributing, and the material distributing moving group is arranged on both sides of the material distributing synchronous cross bar 121, and is restricted by the material distributing synchronous cross bar 121. The material distributing vehicle 11 can move and transport the raw material to the forming mold 2 in a balanced and synchronous manner to evenly distribute the raw material, thereby improving the production quality and production efficiency; when Before forming the prefabricated component, the forming mold 2 can use the side plate cylinder 24 to push the two side plates 23 against the side walls of the bottom plate 21, so as to conveniently surround the forming cavity 20. Compared with the existing mold that assembles the side plates of the mold together one by one to surround the forming cavity before forming the prefabricated component, there is no need to assemble the side plates before forming the prefabricated component each time, and the structure of the forming mold is simpler; when the prefabricated component is formed and needs to be demolded, the side plate cylinder 24 can be used to push the two side plates 23 away from the side walls of the bottom plate 21, and there is no need to remove the side plates 23 and the end plates 22 one by one each time for demolding, and the demolding structure is simpler.

[0080] The length of the side wall of the molding cavity 20 surrounded by the end plate 22 of the present invention is smaller than the length of the side wall of the molding cavity 20 surrounded by the side plate 23; when the prefabricated component is demolded, after the side plate cylinder 24 pushes the two side plates 23 away from the side wall of the bottom plate 21, the two sides of the molding mold 2 are in an open state, and the larger side of the prefabricated component is not restricted by the side plate 23, while the smaller side of the prefabricated component is restricted by the end plate 22. When further demolding is performed, the prefabricated component and the end plate 22 need to be separated, and the connection area between the prefabricated component and the end plate 22 is small, which is relatively easy to demold.

[0081] The frame 100 of the present invention is provided with slide rails 101 extending laterally to the forming mold 2 at both ends, and the fabric cart 11 is provided with two pulleys 111 sliding on the slide rails 101 at both ends; the matching structure of the slide rails 101 and the pulleys 111 can make the fabric cart 11 move more smoothly on the frame 100.

[0082] The material distribution linkage rod 122 of the present invention is L-shaped, and the first force arm 1221 is smaller than the second force arm 1222; the material distribution linkage rod 122 is a labor-saving lever, and the material distribution moving mechanism 12 can transport the raw material to the top of the molding die 2 more labor-savingly and distribute the material evenly.

[0083] The end between the first lever 1221 and the second lever 1222 of the present invention is far away from the cloth cart 11, and the connection between the first lever 1221 and the second lever 1222 is close to the cloth cart 11; the cloth moving mechanism 12 is located on one side of the cloth cart 11, so as to facilitate the movement of the cloth cart 11; the cloth linkage rod 122 is formed with a triangular reinforcing plate 1211 extending to the cloth synchronization cross bar 121 on the side wall of the first lever 1221, and the triangular reinforcing plate 1211 has a first right-angled side connected to the first lever 1221 and a second right-angled side abutting against the cloth synchronization cross bar 121; the cloth linkage rod 122 is firmly connected to the cloth synchronization cross bar 121, and the triangular reinforcing plate 1211 can strengthen the connection relationship between the cloth linkage rod 122 and the cloth synchronization cross bar 121.

[0084] The angle between the first lever arm 1221 and the second lever arm 1222 of the present invention is an obtuse angle, or the angle is greater than or equal to 90° and less than or equal to 180°; the cloth cylinder 124 pushes out or pulls back the first lever arm 1221 to rotate and then drives the second lever arm 1222 to rotate, thereby pushing or pulling back the cloth cart 11.

[0085] The side wall of the material distribution vehicle 11 of the present invention, which is close to the forming mold 2, is provided with a scraper plate 14 which is arranged parallel to the material distribution synchronization cross bar 121. The two ends of the scraper plate 14 are respectively pivoted to the two ends of the material distribution vehicle 11 through a scraper plate connecting rod 141, and the upper end surface of the scraper plate 14 is connected with two symmetrically arranged scraper plate cylinders 142 which can push the scraper plate 14 to move; the material distribution vehicle 11 moves toward the forming mold 2 and feeds the material into the cavity 20. After that, when the material distribution vehicle 11 returns to the material receiving position, it drives the scraper plate 14 to move and flatten the raw material in the cavity 20, so that the raw material is distributed more evenly; the scraper plate 14 is pivoted to the material distribution vehicle 11 through the scraper plate connecting rod 141. When the scraper plate cylinder 142 pushes the scraper plate 14, the position of the scraper plate 14 can be adjusted to facilitate the scraper plate 14 to move and flatten the raw material in the cavity 20, so that the material is distributed more evenly.

[0087] The material distribution vehicle 11 of the present invention has a loading space 112 for carrying raw materials and an upper opening and a lower opening connected to the loading space 112. The width of the lower opening is less than or equal to the width of the cavity 20 of the forming mold 2. When distributing the materials, the materials can be distributed evenly in the horizontal direction. Compared with the existing method of using a scraper to flatten the raw materials after centralized pouring, the material distribution speed is fast and the effect is good. The side wall of the loading space 112 on the side away from the forming mold 2 forms an inclined side wall 113 for pushing the raw materials to move. The inclined side wall 113 can push the raw materials during the movement of the material distribution vehicle 11 Movement makes pushing materials more convenient; the loading space 112 is a tapered structure from the upper opening to the lower opening; the material distributing trolley 11 is provided with a baffle 13 which can block the lower opening, and the top surface of the baffle 13 is flush with the top surface of the cavity 20 of the forming mold 2; when the material distributing trolley 11 moves to leave the baffle 13, the material distributing trolley 11 is located above the cavity 20, and the lower opening is directly opposite to the cavity 20, which is convenient for putting the raw materials in the material distributing trolley 11 into the forming mold and pushing the raw materials above the baffle 13 to the top of the forming mold 2, making the material distributing more convenient and uniform.

[0088] The material distributing vehicle 11 of the present invention is provided with a material discharging mechanism 16 above, and the material discharging mechanism 16 comprises a hopper 161, a hopper valve 162 and a hopper cylinder 163 for controlling the switch of the hopper valve 162; the hopper 161 is in an inverted cone shape and has a material discharging port; the hopper valve 162 is a material baffle plate 164, and the two ends of the material baffle plate 164 have pivotal plates pivotally connected to the two ends of the hopper 161; the piston seat of the hopper cylinder 163 is fixedly arranged on the hopper 1 61 side wall, the piston rod of the hopper cylinder 163 is connected to the baffle plate 164; the hopper cylinder 163 is extended and retracted to drive the baffle plate 164 to open and close the discharge port; when the discharge mechanism 16 is in discharge operation, raw materials can be put into the hopper 161, and the raw materials in the hopper 161 can be freely controlled to be discharged into the distribution vehicle 11 through the matching structure of the hopper valve 162 and the hopper cylinder 163, which makes the discharge more convenient, and the discharge time and amount can be controlled, making it more convenient to use.
