[0034] The following is combined with Figures 1 to 11 The following examples further illustrate the specific implementation of the feeding system of the building contour forming device created by the present invention. The feeding system of the building contour forming device created by the present invention is not limited to the description of the following examples.

[0035] The feeding system of the building contour forming equipment created by the present invention includes a mobile support platform, a forming unit arranged on the mobile support platform, and a feeding system for providing materials to the forming unit. The mobile support platform drives the forming unit to move. The feeding system includes a main feeding unit and at least one relay feeding unit connected to the forming unit. The main feeding unit feeds the forming unit through the relay feeding unit. The relay feeding unit and the main feeding unit are arranged at different heights, and the relay feeding unit transports materials in a horizontal direction. The materials are extruded and printed into a wall through the forming unit.

[0036] like Figure 1-3As shown, the relay feeding unit includes a storage chamber 1 and a pushing mechanism 11 arranged at one end of the relay feeding unit. The other end of the relay feeding unit is connected to the molding unit. A feeding port cooperating with the main feeding unit is provided in the middle of the storage chamber 1. The material falls into the storage chamber 1 through the feeding port, and the material at the bottom of the storage chamber 1 is pushed to the other end of the relay feeding unit by the pushing mechanism 11 and sent to the molding unit.

[0037] The feeding system of the building contour forming equipment created by the present invention provides materials to the forming unit through a relay feeding unit arranged on a mobile support platform. It can not only reduce the distance for directly feeding the forming unit from the ground, but also ensure that the materials are centrally stored in the storage chamber 1 of the relay feeding unit, thereby avoiding blockage of the feeding system during the material transportation process.

[0038] Furthermore, the relay feeding unit also includes an extrusion chamber 2 provided on one side of the storage chamber 1. The storage chamber 1 is connected to the forming unit via the extrusion chamber 2. The volume of the extrusion chamber 2 is smaller than that of the storage chamber 1, and an extrusion mechanism 21 is provided within the extrusion chamber 2. After the material is extruded through the extrusion chamber 2, it not only facilitates the relay feeding unit to transport the material to the forming unit, but also helps to improve the quality of the wall formed by the forming unit.

[0039] Furthermore, the relay feeding unit also includes a vibration mechanism, which can drive the material in the relay feeding unit to vibrate, thereby improving the workability of the material and making the wall printed by the molding unit stronger and the wall surface smoother.

[0040] Furthermore, the relay feeding unit also includes a crushing mechanism 31 provided at the feeding port. The crushing mechanism 31 crushes the material, which not only facilitates the mixing of the material in the storage chamber 1, but also allows the material to be pre-crushed on the ground to a size that is convenient for conveying by the main feeding unit, and then the crushing mechanism 31 crushes the material to a size that is convenient for molding by the molding unit.

[0041] As a first embodiment of the main feeding unit, the main feeding unit includes a main feeding bin arranged on the ground and a feeding pipe connected to the main feeding bin. The main feeding unit feeds the relay feeding unit through the feeding pipe, or the mobile support platform can drive the relay feeding unit to move toward the main feeding unit, and add materials to the relay feeding unit through the main feeding unit.

[0042] As a second embodiment of the main feeding unit, the main feeding unit includes a main feeding bin, a feeding pipe and a robotic arm. One end of the feeding pipe is connected to the main feeding bin, and the other end of the feeding pipe is installed on the robotic arm. The robotic arm can drive the feeding pipe to add materials to the relay feeding unit.

[0043] like Figure 9As shown, the molding unit of this embodiment includes an extrusion mechanism 41 and a flow control mechanism 40 (not shown). One end of the extrusion mechanism 41 is connected to the relay feeding unit, and the other end of the extrusion mechanism 41 is provided with an extrusion port. The flow control mechanism 40 is a pneumatic valve or flow stabilizer that cooperates with the extrusion port. The flow control mechanism 40 can accurately control the flow rate of the material extruded by the extrusion mechanism 41, thereby improving the quality of the formed wall.

[0044] Furthermore, the molding unit further includes a molding bracket 42 connected to the movable support platform, and the extrusion mechanism 41 is directly detachably connected to the molding, so that the extrusion mechanism 41 can be easily removed for replacement and cleaning.

[0045] like Figure 1-3 The preferred embodiment of the relay feeding unit created by the present invention is shown. The relay feeding unit of this embodiment includes a storage chamber 1, a crushing chamber 3 arranged above the storage chamber 1, and an extrusion chamber 2 and a pushing mechanism 11 respectively arranged at both ends of the relay feeding unit. The extrusion chamber 2 is provided with an extrusion mechanism 21, and the crushing chamber 3 is provided with a crushing mechanism 31. A feed port connected to the crushing chamber 3 is provided in the middle of the storage chamber 1, one end of the extrusion chamber 2 is connected to the storage chamber 1, and the other end of the extrusion chamber 2 is provided with a discharge port 20 for connecting to the molding unit. A flow control valve is provided at the discharge port 20, a discharge port 10c and multiple feed ports are provided in the middle of the storage chamber 1, and the discharge port 10c can be used to facilitate the discharge of materials in the storage chamber 1 and facilitate cleaning. The multiple feed ports include a flange interface 10a for adding liquid materials and a solid feed port 10b for adding solids. The relay feeding unit includes a crushing chamber 3 arranged above the storage chamber 1, and the bottom of the crushing chamber 3 is connected to the storage chamber 1 through the solid feed port 10b. After the materials provided by the main feeding unit are separated into dry and wet types, the small-sized materials directly enter the storage chamber 1, and the large-sized materials enter the storage chamber 1 after being crushed by the crushing mechanism 31 in the crushing chamber 3. The liquid materials enter the storage chamber 1 through the flange interface 10a, and the pushing mechanism 11 pushes the various materials in the storage chamber 1 to mix, and then move to the molding unit through the extrusion chamber 2.

[0046] like Figure 1-3A preferred embodiment of the pushing mechanism 11 and the extrusion mechanism 21 is shown. The pushing mechanism 11 includes a pushing shaft 111 and a drive motor 112. One end of the pushing shaft 111 is connected to the drive motor 112, and the other end of the pushing shaft 111 extends into the storage chamber 1. A spiral conveying piece 114 is provided on the circumference of the pushing shaft 111 facing the extrusion chamber 2. The drive motor 112 rotates the pushing shaft 111 to push the material toward the extrusion chamber 2 through the spiral conveying piece 114. The structure of the pushing shaft 111 and the spiral conveying piece 114 pushes the material. During the pushing process, the material at the bottom can be lifted, making the material at the bottom and top more uniform, avoiding the material from being deposited at the bottom. This not only ensures the uniformity of the material, but also has the characteristics of low structural cost and not easy to be blocked. The spiral conveying piece 114 is preferably a spiral structure arranged along the length direction of the pushing shaft 111, and an independent spiral blade can also be used. Of course, the pushing mechanism 11 can also adopt a piston type, or other methods of pushing the material, which all fall within the scope of protection created by the present invention. The axial direction of the pushing shaft 111 is parallel to the platform on which the subsequent feeding unit is installed.

[0047] Furthermore, the extrusion mechanism 21 includes an extrusion shaft 211 disposed within the extrusion chamber 2. An extrusion member is provided on the circumference of the extrusion shaft 211. The extrusion member can push the material toward the side wall of the extrusion chamber 2 when the extrusion shaft 211 rotates. The extrusion shaft 211 and the pusher shaft 111 of the pusher mechanism 11 are disposed on the same straight line, and the extrusion shaft 211 is connected to the pusher shaft 111 via a universal joint 212. When the pusher shaft 111 rotates, the extrusion shaft 211 is driven to rotate by the universal joint 212, thereby stirring the material within the extrusion chamber 2 and facilitating the material to leave the extrusion chamber 2 from the discharge port 20. The axial direction of the extrusion shaft 211 is parallel to the platform on which the relay feeding unit is mounted. The spiral shaft 211 not only extrudes the material, but also has a slight stirring function to ensure that the material still has a certain fluidity after extrusion and prevent blockage. In addition, the universal joint 212 is connected between the spiral shaft 211 and the pusher shaft 111, so that the spiral shaft 211 and the pusher shaft 111 can be driven by a drive motor 112 of the pusher mechanism 11, and it also has the characteristics of anti-jamming, high flexibility and low motor torque requirement.

[0048] Furthermore, the extrusion shaft 211 is wavy, and the extrusion piece is a wavy protrusion on the extrusion shaft 211. Of course, the extrusion shaft 211 can also be a straight structure, and the extrusion piece is a protrusion on the extrusion shaft 211.

[0049] Furthermore, the extrusion chamber 2 includes a second extrusion chamber 20b for accommodating the extrusion shaft 21, and a first extrusion chamber 20a communicating between the second extrusion chamber 20b and the storage chamber 1. The inner diameter of the first extrusion chamber 20a is smaller than that of the storage chamber 1 and larger than that of the second extrusion chamber 20b. A steel sheath is provided on the outer side of the universal joint 212. A spiral blade 213 facing the second extrusion chamber 20b is provided at the end of the push shaft 111 near the steel sheath. The spiral blade 213 and the universal joint 212 are respectively disposed within the first extrusion chamber 20a. The steel sheath protects the universal joint 212. The material in the storage chamber 1 passes through the first extrusion chamber 20a and into the second extrusion chamber 20b, ensuring uniformity during the extrusion process and preventing blockage.

[0050] like Figure 10-11 As shown, the storage chamber 1 is provided with a connecting chamber 113 at one end near the drive motor 112. The drive motor 112 is detachably mounted on the connecting chamber 113. One end of the push shaft 111 extends into the connecting chamber 113 and is connected to the drive motor 112. Preferably, one side of the end of the drive motor 112 is pivotally connected to one side of the connecting chamber 113, and a manual buckle 114 is provided on the other side of the connecting chamber 113 for fixing the other side of the end of the drive motor 112. When the drive motor 112 and the connecting chamber 113 are fixed by the manual buckle 114, a reliable connection is ensured. When the manual buckle 114 is unlocked, the drive motor 112 can be rotated 180 degrees to open the connecting chamber 113, making it easier to clean the connecting chamber 113 and the drive motor 112.

[0051] like Figure 2 A preferred embodiment of the crushing mechanism 31 is shown. The crushing mechanism 31 includes a crushing element 311 and a crushing motor 312. The crushing motor 312 drives the crushing element 311 to rotate, and the crushing element 311 pushes and squeezes the material against the inner wall of the crushing chamber 3 to crush the material. The crushing mechanism 31 can crush the dry material before adding it to the storage chamber 1. Of course, depending on the hardness and particle size of the material, the crushing mechanism 31 can also use other crushing methods, such as jaw crushing or roller crushing, which are not specifically limited here.

[0052] like Figure 9 As shown, a funnel-shaped elevated hopper 32 is provided above the crushing chamber 3. The inner diameter of the elevated hopper 32 decreases gradually from top to bottom, which not only facilitates the addition of materials into the elevated hopper 32, but also facilitates the crushing mechanism 31 to perform crushing.

[0053] The mobile support platform of this embodiment includes an X-axis moving mechanism 51, a Y-axis moving mechanism 52 and a Z-axis moving mechanism 53. The X-axis moving mechanism 51, the Y-axis moving mechanism 52 and the Z-axis moving mechanism 53 cooperate to drive the forming unit to move in three mutually perpendicular X-axis, Y-axis and Z-axis directions in a three-dimensional space, so as to accurately extrude the material at a predetermined position to form a wall. The X-axis and the Y-axis are arranged perpendicular to each other in a horizontal plane, and the Z-axis is perpendicular to the horizontal plane where the X-axis and the Y-axis are located.

[0054] like Figure 4-5 A first embodiment of a mobile support platform is shown. In this embodiment, the molding unit is arranged on the Z-direction moving mechanism 53, the X-direction moving mechanism 51 is arranged at a high altitude through a bracket, the Y-direction moving mechanism 52 is arranged on the X-direction moving mechanism 51 and moves along the X-axis direction, the Z-direction moving mechanism 53 is arranged on the Y-direction moving mechanism 52 and moves along the Y-axis direction, the molding unit is arranged on the Z-direction moving mechanism 53 and moves along the Z-axis direction, and the relay feeding unit is arranged on the X-direction moving mechanism 51 or the Y-direction moving mechanism 52 to feed the molding unit.

[0055] Specifically, the X-direction moving mechanism 51 includes two parallel X-direction rails and X-direction driving mechanisms respectively arranged on the X-direction rails. The Y-direction moving mechanism 52 includes a Y-direction rail vertically connected between the two X-direction rails and a Y-direction driving mechanism arranged on the Y-direction rail. The Z-direction moving mechanism 53 includes a Z-direction driving mechanism connected to the Y-direction rail and a Z-direction rail connected to the Z-direction driving mechanism. The forming unit is arranged on the Z-direction rail. The X-direction driving mechanism drives the Y-direction rail to move along the X-direction rail, the Y-direction driving mechanism drives the Z-direction rail to move along the Y-direction rail, and the Z-direction driving mechanism drives the Z-direction rail to move along the Z-direction rail. The forming unit is fixedly connected to the Z-direction rail.

[0056] The X-axis driving mechanism, Y-axis driving mechanism and Z-axis driving mechanism can be electric motors, and the X-axis track and Y-axis track are preferably connected by rollers. In addition, there can be multiple Z-axis moving mechanisms 53. For example, the X-axis moving mechanism 51 can be installed on another Z-axis moving mechanism 53, and the Z-axis moving mechanism 53 drives all the mechanisms of the mobile support platform to move up and down, and then the Z-axis moving mechanism 53 installed on the Y-axis moving mechanism 52 drives the molding unit to fine-tune the vertical position. The number of X-axis tracks can also be three or more. In addition, there can also be multiple molding units, and multiple molding units are respectively installed on different Z-axis moving mechanisms 53, and different parts of the building are printed separately by multiple molding units.

[0057] like Figure 4-7As shown, the relay feeding unit is connected to the Y-direction track of the mobile support platform through a relay moving mechanism, and the relay moving mechanism can drive the relay feeding unit to move along the length direction of the Y-direction track. By moving the relay feeding unit along the length direction of the Y-direction track, it is possible to avoid being too far away from the molding unit during operation, ensuring that materials are supplied to the molding unit at a close distance. Preferably, the relay moving mechanism includes a relay mobile platform 131 and a relay driving mechanism. The relay mobile platform 131 is connected to the Y-direction track through a chain 132. The relay feeding unit is installed on the relay mobile platform 131. The relay driving mechanism drives the relay mobile platform 131 to move along the Y-direction track.

[0058] Of course, the relay feeding unit may not be moved, and the relay feeding unit may be fixedly installed at the end of the Y-direction track or the end of the X-direction track. The fixed setting of the relay feeding unit has the characteristics of reliability and stability, which all fall within the protection scope of the invention.

[0059] like Figure 8 A second embodiment of the mobile support platform is shown. In this embodiment, the molding unit is arranged on the Y-direction moving mechanism 52, the X-direction moving mechanism 51 is arranged on the ground, the Z-direction moving mechanism 53 is arranged on the X-direction moving mechanism 51 and moves along the X-axis direction, the Y-direction moving mechanism 52 is arranged on the Z-direction moving mechanism 53 and moves along the Z-axis direction, the molding unit is arranged on the Y-direction moving mechanism 52 and moves along the Y-axis direction, and the relay feeding unit is arranged on the Y-direction moving mechanism 52 or the Z-direction moving mechanism 53 to feed the molding unit.

[0060] Specifically, the X-direction moving mechanism 51 includes two parallel X-direction rails and X-direction driving mechanisms respectively arranged on the X-direction rails. The Z-direction moving mechanism 53 includes two Z-direction rails respectively connected to the two X-direction rails and two Z-direction driving mechanisms respectively arranged on the two Z-direction rails. The Y-direction moving mechanism 52 includes a Y-direction rail vertically connected between the two Y-direction rails and a Y-direction driving mechanism arranged on the Y-direction rail. The molding unit is arranged on the Y-direction rail. The X-direction driving mechanism drives the Z-direction rail to move along the X-direction rail, the Z-direction driving mechanism drives the Y-direction rail to move along the Z-direction rail, and the Y-direction driving mechanism drives the molding unit to move along the Y-direction rail.

[0061] In this embodiment, the relay feeding unit and the molding unit are both arranged on the Y-direction moving mechanism 52. Not only are the distance between the relay feeding unit and the molding unit closer and they can be connected for feeding through a rigid pipe, but the relay feeding unit and the molding unit can also move together along the Y-direction moving mechanism 52 under the drive of the same driving mechanism.

[0062] Furthermore, the molding unit includes an extrusion mechanism 41 and a molding bracket 42 . The molding bracket 42 is movably mounted on a Y-axis track, and the extrusion mechanism 41 and the molding bracket 42 are detachably connected. Specifically, a connector 43 connected to a forming bracket 42 is provided on one side of the extrusion mechanism 41. One end of the connector 43 is connected to the extrusion mechanism 41, and the other end of the connector 43 is provided with a limit plate 47. The forming bracket 42 is provided with a fixed limiter 44 and a pivot limiter 45, which respectively cooperate with both sides of the limit plate 47. One end of the pivot limiter 45 is rotatably mounted on the forming bracket 42, and the other end of the pivot limiter 45 cooperates with a locking limiter 46. When the locking limiter 46 locks the pivot limiter 45, it can prevent the pivot limiter 45 from rotating, so that the pivot limiter 45 and the fixed limiter 44 respectively limit the limit plate 47 from both sides. When the locking limiter 46 unlocks the pivot limiter 45, the pivot limiter 45 can avoid the limit plate 47, facilitating the removal and replacement of the extrusion mechanism 41. The pivot limiter 45 is preferably a guillotine, and the locking limiter 46 is preferably a ring nut. Preferably, the forming bracket 42 is L-shaped, the Y-direction track is arranged on the inner side of the forming bracket 42 , the basic unit is connected to the outer side of one end of the forming bracket 42 , and the relay feeding unit is connected to the outer side of the other end of the forming bracket 42 .

[0063] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art to which the present invention belongs, simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered to fall within the scope of protection of the present invention.
