DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] Embodiment 1, as Figure 1-Figure 12 As shown, an automatic demoulding building material forming machine described in an embodiment of the present invention includes a body 1, and also includes: a number of No. 1 rods 2 installed on the body 1; a number of No. 2 rods 3 fixedly installed on the body 1, and the No. 2 rods 3 adopt a telescopic structure; a mold assembly 4 installed on the No. 1 rod 2 and the No. 2 rod 3, and the mold assembly 4 includes: a base 41 fixedly installed on the No. 1 rod 2; a frame 42 fixedly installed on the No. 2 rod 3, and the base 41 and the frame 42 are slidably connected; four No. 1 connecting blocks 43 symmetrically and fixedly installed on the frame 42; a cylinder 44 rotatably installed on the No. 1 connecting block 43; and a round rod 45 threadedly connected in the cylinder 44.

[0037] Specifically, when it is necessary to make foamed cement boards, an automatic demoulding building material forming machine is required to be used. The slurry formed by mixing and fusing materials such as cement, foaming agent, hydrogen peroxide and fly ash is poured into the forming machine. When the slurry is foamed and solidified into a larger block in the machine, the solidified slurry is taken out of the forming machine, and then a cutting device is used to cut the large block of solid slurry into several small blocks, namely the foamed cement board. In order to facilitate the separation of the solid slurry and the mold during demoulding, a plastic film needs to be put into the mold before pouring, and then the slurry is poured into the mold for foaming and solidification operations. After the solid slurry is demoulded from the mold, the existing device needs to use an additional device to remove the plastic film on the solid slurry. The second rod 3 adopts an electric telescopic rod. In the initial state, the position between the bottom plate and the frame 42 is as shown in Figure 1As shown, the second rod 3 is in an extended state. Before work, a plastic film is put on the bottom plate and the frame. After the plastic film is put on, the upper end of the plastic film is bent so that the plastic film of the bent part is put on the outer periphery of the frame 42. The round rod 45 is controlled to rotate relative to the cylinder 44. Since the round rod 45 and the cylinder 44 are threadedly connected, the round rod 45 can move in a direction close to the frame 42 after rotation until the round rod 45 is in close contact with the plastic film put on the outer periphery of the frame 42, that is, the action of fixing the plastic film is completed, and then the slurry is poured into the interior of the mold assembly 4. After the pouring is completed, the slurry is waited for foaming and solidification. After the slurry foaming and solidification are completed, the second rod 3 is controlled to shrink downward. The second rod 3 shrinks downward The frame 42 is driven to move downward synchronously. Since the upper end of the plastic film is fixed on the frame 42, the plastic film can be pulled to separate from the solid slurry during the downward movement of the frame 42. When the solid slurry is completely exposed, the demoulding action is completed, and then the transportation device can be used to remove the slurry from the bottom plate. By setting the mold assembly 4, the upper end of the plastic mold can be fixed, avoiding the problem that the upper end of the plastic film enters the frame 42 during the pouring of the slurry, so that the slurry directly contacts the frame 42 and the base 41, and in the process of demoulding, it can be automatically separated from the side wall of the solid slurry, without the need to use additional devices to peel the plastic mold, which is easy to use.

[0038] like Figure 2-Figure 6 As shown, it also includes: a mounting frame 5 fixedly mounted on the body 1, the mounting frame 5 is used to mount the wound plastic film; a No. 1 connecting rod 6 and a No. 2 connecting rod 7 mounted on the body 1; two slide grooves 26 respectively mounted on the No. 1 connecting rod 6 and the No. 2 connecting rod 7; three clamps 8 slidably mounted on the slide grooves 26, the clamps 8 are used to clamp the plastic film; a cutter 9 mounted on the body 1, the cutter 9 is used to cut the plastic film; a square plate 10 mounted between the No. 1 connecting rod 6 and the No. 2 connecting rod 7; a No. 3 rod 11 mounted on the square plate 10, the No. 3 rod 11 adopts a telescopic structure; a spreading component 12 fixedly mounted on the No. 3 rod 11, the spreading component 12 includes a No. 1 round telescopic rod 121.

[0039] Specifically, the third rod 11 adopts an electric telescopic rod, with the side where the mounting frame 5 is located as the right side of the machine body 1. In the initial state, the clamps 8 are all located on the right side of the mold assembly 4, and the end of the plastic film is fixed on the clamp 8 located on the far left. Before work, the other two clamps 8 are controlled to loosen the plastic film, and the clamp 8 holding the end of the plastic film is controlled to slide to the left until the clamp 8 is located on the far left of the slide groove 26. At this time, the plastic film is located above the mold assembly 4, and the other two clamps 8 are controlled to clamp the side of the plastic film. The cutter 9 is controlled to extend downward to cut the plastic film between the two clamps 8 on the right side, and the third rod 11 is controlled to extend downward to drive the opening assembly 12 to move downward synchronously. Move until the stretching assembly 12 contacts the base 41, and then control the No. 1 back-shaped telescopic rod 121 to stretch outward in a back shape, so that the plastic film is unfolded by the No. 1 back-shaped telescopic rod 121 until it contacts the base 41, and then control the No. 3 rod 11 to retract upward, driving the No. 1 back-shaped telescopic rod 121 in the extended state to move upward synchronously, so that the plastic film fits the inner wall of the frame 42; when the No. 1 back-shaped telescopic rod 121 moves out of the interior of the mold assembly 4, control the No. 1 back-shaped telescopic rod 121 to retract to the initial state, control the two clamps 8 on the left side to release the plastic film, and then fix the upper end of the plastic film, thereby completing the action of putting the plastic film on the mold assembly 4.

[0040] like Figure 3 , Fig. 9 and Fig.10 As shown, the expansion assembly 12 also includes: a No. 1 plate 122 fixedly mounted at the lower end of the No. 3 rod 11; four No. 1 rotating rods 123 symmetrically and rotatably mounted on the No. 1 plate 122, the other end of the No. 1 rotating rod 123 being rotatably connected to the No. 1 circular telescopic rod 121; a No. 2 ratchet 124 fixedly mounted on the No. 1 rotating rod 123; a No. 2 rack plate 125 slidably mounted on the No. 1 plate 122, the No. 2 rack plate 125 being meshed and connected with the No. 2 ratchet 124, the No. 2 rack plate 125 adopts a telescopic structure, and the No. 2 rack plate 125 is used to limit the unidirectional rotation of the No. 2 ratchet 124.

[0041] Specifically, since one end of the No. 1 rotating rod 123 rotates with the No. 1 plate 122, and the other end of the No. 1 rotating rod 123 is rotatably connected with the No. 1 circular telescopic rod 121, when the No. 1 circular telescopic rod 121 contacts the base 41 and the No. 3 rod 11 continues to extend downward, the No. 1 plate 122 moves downward synchronously, and the No. 1 rotating rod 123 rotates in the direction away from each other, and pushes the No. 1 circular telescopic rod 121 to extend outward in a circular shape to achieve the action of stretching the plastic film. When the No. 1 rotating rod 123 rotates, it drives the No. 2 ratchet wheel 124 to rotate synchronously. Restricted by the No. 2 rack plate 125, after the No. 1 rotating rod 123 rotates The first plate 122 is moved upward to make the plastic film fit with the inner wall of the frame 42. After the first plate 122 is moved out of the mold assembly 4, the second rack plate 125 can be controlled to slide in the direction away from the second ratchet wheel 124 until the second ratchet wheel 124 is not in contact with the second rack plate 125. At this time, the first rotating rod 123 is rotated in the direction of approaching each other by the gravity of the first plate 121, so that the first plate 121 is contracted to its initial state.

[0042] like Figure 5 , Fig. 9 and Fig.10 As shown, the mold assembly 4 also includes a No. 2 round telescopic rod 46 fixedly mounted on the round rod 45, the No. 2 round telescopic rod 46 is located at the outer periphery of the frame 42, the No. 1 round telescopic rod 121 is fixedly mounted with a No. 2 connecting block 13, the No. 3 connecting rod 14 is rotatably mounted on the No. 2 connecting block 13, the No. 4 rod 15 is fixedly mounted on the No. 3 connecting rod 14, and the No. 4 rod 15 adopts a telescopic structure.

[0043] like Figure 7 and Figure 8 As shown, the mold assembly 4 also includes: a No. 1 ratchet 47 fixedly mounted on the cylinder 44; a No. 2 plate 48 slidably mounted on the No. 1 connecting block 43; a No. 1 spring 49 mounted between the No. 2 plate 48 and the No. 1 connecting block 43; a No. 1 rack plate 411 slidably mounted on the No. 2 plate 48, the No. 1 ratchet 47 being meshed and connected with the No. 1 rack plate 411; and a No. 2 spring 410 mounted between the No. 2 plate 48 and the No. 1 rack plate 411.

[0044] Specifically, after the No. 1 circular telescopic rod 121 moves to the top of the side wall of the frame 42, the No. 3 connecting rod 14 is controlled to rotate 90 degrees in the direction close to the No. 2 circular telescopic rod 46 until the No. 3 connecting rod 14 is located above the No. 2 circular telescopic rod 46. During the rotation process, the No. 3 connecting rod 14 contacts the No. 2 plate 48 and pushes the No. 2 plate 48 to move downward. At this time, the No. 1 spring 49 is in a compressed state, and the No. 2 plate 48 moves downward to drive the No. 1 rack plate 411 to move downward synchronously. Since the cylinder 44 cannot rotate at this time, the No. 1 ratchet 47 remains stationary, and the No. 4 rod 15 is controlled to extend downward until the No. 4 rod 15 is inserted between the outer wall of the frame 42 and the No. 2 circular telescopic rod 46. Since the plastic film covers the frame 42 and the No. 2 circular telescopic rod 46, the No. 4 rod 15 extends downward, which can make part of the plastic mold recessed between the outer wall of the frame 42 and the No. 2 circular telescopic rod 46. Then the No. 4 rod 15 is controlled to shrink to its original state, and the No. 3 When the connecting rod 14 rotates to a vertical state, during the rotation of the third connecting rod 14, the second plate 48 moves upward under the action of the elastic force of the first spring 49, and the second plate 48 moves upward to drive the first rack plate 411 to move upward synchronously. At this time, the movement of the first rack plate 411 can drive the first ratchet 47 to rotate, and the rotation of the first ratchet 47 drives the cylinder 44 to rotate. The rotation of the cylinder 44 can make the round rod 45 move in the direction close to the outer wall of the frame 42, and the round rod 45 moves, pushing the second circular telescopic rod 46 to shrink toward the frame 42 in a circular shape until the second circular telescopic rod 46 is tightly attached to the outer wall of the frame 42, so as to fix the upper end of the plastic film, which is convenient to use. The second circular telescopic rod 46 adopts a circular shape, which increases the fixing point of the plastic mold compared to the circular rod 45, and reduces the probability of unsuccessful separation of the plastic film and the solid slurry due to the tight connection between the plastic mold and the solid slurry during demoulding.

[0045] like Figure 4 and Figure 6 As shown, the No. 1 connecting rod 6 and the No. 2 connecting rod 7 are slidingly connected, the No. 1 plate 122 is slidingly connected to the No. 1 connecting rod 6 and the No. 2 connecting rod 7, and two No. 2 rotating rods 16 are rotatably installed on the No. 1 plate 122, and the other ends of the two No. 2 rotating rods 16 are rotatably connected to the No. 1 connecting rod 6 and the No. 2 connecting rod 7 respectively.

[0046] Specifically, in the initial state, the plastic film on the clamp 8 is in a straightened state. By setting a No. 1 connecting rod 6 and a No. 2 connecting rod 7 that can slide relative to each other, during the downward extension of the No. 3 rod 11, the No. 1 plate 122 moves downward synchronously. Since one end of the No. 2 rotating rod 16 is connected to the No. 1 connecting rod 6 or the No. 2 connecting rod 7, and the other end is rotatably connected to the No. 1 plate 122, the No. 2 rod 3 rotates and pulls the No. 1 connecting rod 6 or the No. 2 connecting rod 7 to move horizontally in the direction close to the square plate 10. The No. 1 connecting rod 6 or the No. 2 connecting rod 7 moves in a direction close to each other, so the clamps 8 on the front and rear sides approach each other, so that the plastic film gradually relaxes, and the plastic film is tightened by the downward pulling of the No. 1 circular telescopic rod 121. Compared with the method of unfolding the plastic film in a relaxed state, this unfolding method uses less plastic mold and reduces the generation of wrinkles when the plastic film is fitted with the inner wall of the frame 42.

[0047] like Figure 1 , Figure 2 and Figure 5 As shown, the No. 1 rod 2 adopts a telescopic structure, the No. 1 rod 2 and the base 41 are rotatably connected, and a sliding frame 17 is fixedly installed on the body 1.

[0048] Specifically, after demoulding, the two No. 1 rods 2 on the right are controlled to extend upward, driving the base 41 to tilt to the left, so that the solid slurry can slide downward along the base 41 and the sliding frame 17, which is convenient for subsequent transportation.

[0049] like Figure 2 and Figure 3 As shown, a circular plate 18 is rotatably mounted on the machine body 1 , the No. 1 rod 2 is fixedly connected to the circular plate 18 , and a monitor 19 is fixedly mounted on the side wall of the machine body 1 .

[0050] Specifically, affected by factors such as internal temperature and load during the hardening process of the slurry, the solid slurry may crack after demolding. If cracks exist, they can be treated by caulking, filling or re-pouring. The monitoring 19 can take pictures of the side walls of the solid slurry after demolding, and feed the results of the pictures back to the control center, and process the pictures to determine whether the solid slurry has cracks, so as to promptly treat the cracked solid slurry.

[0051] like Figure 3 , Fig.11 and Fig.12 As shown, it also includes: a No. 1 connecting plate 20 fixedly mounted on the side wall of the body 1; a No. 2 connecting plate 21 slidably mounted on the No. 1 connecting plate 20; a No. 1 telescopic rod 22 slidably mounted on the No. 2 connecting plate 21; a disc 23 mounted on the No. 1 telescopic rod 22, and a chalk 24 is mounted on the disc 23.

[0052] Specifically, after the monitoring device 19 is filmed, if there is a crack, the No. 2 connecting plate 21 is controlled to slide left and right, and the No. 1 telescopic rod 22 is controlled to move up and down, driving the disc 23 to move synchronously. The movement of the disc 23 can drive the chalk 24 to move until the chalk 24 moves around the crack, and then the No. 1 telescopic rod 22 is controlled to extend until the chalk 24 fits with the solid slurry, and the No. 2 connecting plate 21 is controlled to slide left and right and the No. 1 telescopic rod 22 is controlled to move, driving the chalk 24 to move around the crack to mark, so that the staff can directly handle it and it is easy to use.

[0053] like Figure 3 , Fig.11 and Fig.12 As shown, compared with Example 1, another implementation of the present invention is: the chalk 24 is slidably connected to the disc 23, the disc 23 is rotatably connected to the first telescopic rod 22, a plurality of chalks 24 are provided on the disc 23, and a second telescopic rod 25 is fixedly installed on the first telescopic rod 22.

[0054] Specifically, the position of the chalk 24 in contact with the No. 2 telescopic rod 25 is the working station. The No. 2 telescopic rod 25 is extended to push the chalk 24 on the working station to move in the direction close to the mold assembly 4. When the chalk 24 is used up, the No. 2 telescopic rod 25 is controlled to shrink to no longer contact with the disc 23, and the disc 23 is controlled to rotate so that the unused chalk 24 moves to the working station. The No. 2 telescopic rod 25 is controlled to extend to push the unused chalk 24 to move in the direction close to the mold assembly 4. This allows for recycling, reducing the frequency of replacement and being easy to use.

[0055] Working principle: In the initial state, the clamps 8 are all located on the right side of the mold assembly 4, and the end of the plastic film is fixed on the clamp 8 located on the far left. Before working, the other two clamps 8 are controlled to release the plastic film, and the clamp 8 holding the end of the plastic film is controlled to slide to the left until the clamp 8 is located on the far left of the slide slot 26. At this time, the plastic film is located above the mold assembly 4, and the other two clamps 8 are controlled to clamp the side of the plastic film. The cutter 9 is controlled to extend downward to cut the plastic film between the two clamps 8 on the right side, and the third rod is controlled. The first circular telescopic rod 121 is controlled to extend outward in a circular shape, so that the plastic film is unfolded by the first circular telescopic rod 121 until it contacts the base 41. The third rod 11 is controlled to retract upward, so that the first circular telescopic rod 121 in the extended state moves upward synchronously, so that the plastic film fits the inner wall of the frame 42. After the first circular telescopic rod 121 moves to the top of the side wall of the frame 42,

[0056] The two clamps 8 on the left are controlled to release the plastic film, and the No. 3 connecting rod 14 is controlled to rotate 90 degrees towards the direction close to the No. 2 circular telescopic rod 46 until the No. 3 connecting rod 14 is located above the No. 2 circular telescopic rod 46. During the rotation process, the No. 3 connecting rod 14 contacts the No. 2 plate 48 and pushes the No. 2 plate 48 to move downward. At this time, the No. 1 spring 49 is in a compressed state, and the No. 2 plate 48 moves downward to drive the No. 1 rack plate 411 to move downward synchronously. Since the cylinder 44 cannot rotate at this time, the No. 1 ratchet 47 remains stationary, and the No. 4 rod 15 is controlled to extend downward until the No. 4 rod 15 is extended downward. The No. 4 rod 15 is inserted between the outer wall of the frame 42 and the No. 2 circular telescopic rod 46. Since the plastic film covers the frame 42 and the No. 2 circular telescopic rod 46, the No. 4 rod 15 extends downward, which can make part of the plastic mold recessed between the outer wall of the frame 42 and the No. 2 circular telescopic rod 46. Then, the No. 4 rod 15 is controlled to shrink to the original state, and the No. 3 connecting rod 14 is controlled to rotate to a vertical state. During the rotation of the No. 3 connecting rod 14, the No. 2 plate 48 moves upward under the action of the elastic force of the No. 1 spring 49, and the No. 2 plate 48 moves upward to drive the No. 1 rack plate 411 to move upward synchronously At this time, the movement of the No. 1 rack plate 411 can drive the No. 1 ratchet 47 to rotate, and the rotation of the No. 1 ratchet 47 drives the cylinder 44 to rotate. The rotation of the cylinder 44 can make the round rod 45 move toward the outer wall of the frame 42. The round rod 45 moves, pushing the No. 2 back-shaped telescopic rod 46 to shrink toward the frame 42 in a back shape until the No. 2 back-shaped telescopic rod 46 is tightly attached to the outer wall of the frame 42, so that the upper end of the plastic film can be fixed, and the No. 1 back-shaped telescopic rod 121 is controlled to continue to move upward. When the No. 1 back-shaped telescopic rod 121 moves out of the interior of the mold assembly 4, the No. 1 back-shaped telescopic rod 121 is controlled to shrink. When the mold assembly 4 is shrunk to its initial state, the action of putting the plastic film on the mold assembly 4 is completed, and then the slurry is poured into the interior of the mold assembly 4. After the pouring is completed, wait for the slurry to foam and solidify. After the slurry foaming and solidification are completed, the No. 2 rod 3 is controlled to shrink downward. The downward contraction of the No. 2 rod 3 drives the frame 42 to move downward synchronously. Since the upper end of the plastic film is fixed on the frame 42, the plastic film can be pulled to separate from the solid slurry during the downward movement of the frame 42. After the solid slurry is fully exposed, the demoulding action is completed, and then the slurry can be removed from the bottom plate by a transportation device.
