[0033] This embodiment provides a demoulding and stacking integrated machine for molded concrete products. Figures 1-5 As shown, it includes a frame 100, and a conveying and flipping mold device 200, a conveying and demoulding device 300, a conveying and stacking device 400 and a lifting receiving device sequentially arranged on the frame 100; the conveying and flipping mold device 200 includes a front input mechanism 210, a flipping mold mechanism 220 and a rear output mechanism 230 sequentially arranged on the frame 100, and the flipping mold mechanism 220 is rotatably arranged between the front and rear conveying mechanisms; the conveying and demoulding device 300 includes a demoulding conveying mechanism 310 and a vibrating demoulding mechanism 320 arranged on the frame 100, and the vibrating demoulding mechanism 320 has a receiving portion 321 arranged above the demoulding conveying mechanism 310, which is used to receive the concrete product 500 mold 6 output by the flipping mold. 00 and vibrates to make the concrete product 500 fall off the demoulding conveying mechanism 310; the conveying and stacking device 400 includes a primary input mechanism 410, a secondary transfer platform 420 and a blocking unloading mechanism 430 arranged on the frame 100; the secondary transfer platform 420 is arranged between the output end of the primary input mechanism 410 and the upper part of the lifting and receiving device so as to be horizontally reciprocatingly movable; the output end of the blocking unloading mechanism 430 is movably arranged on the upper part of the lifting and receiving device, and when the secondary transfer platform 420 is moved out to the upper part of the lifting and receiving device, it is used to block the concrete product 500 on the secondary transfer platform 420, so that it is blocked and falls to the lifting and receiving device when the secondary transfer platform 420 is moved back.

[0034] Specifically, the front input mechanism 210 is used to transport the mold 600 containing the concrete product 500 to the mold flipping mechanism 220. After the mold flipping mechanism 220 flips the mold 600, it is output through the rear output mechanism 230 and input into the receiving part 321 of the vibration demoulding mechanism 320. The flipped concrete product 500 is demoulded from the mold 600 by the vibration demoulding mechanism 320 and falls onto the demoulding conveying mechanism 310; the demoulded concrete product 500 is input to the secondary transfer platform 420 through the primary input mechanism 410, the secondary transfer platform 420 is moved out to the upper part of the lifting receiving device, and the concrete product 500 is blocked by the blocking unloading mechanism 430, and then the secondary transfer platform 420 is moved back to the primary input mechanism 410. During this period, the concrete product 500 is blocked by the blocking unloading mechanism 43 and falls to the lifting receiving device; in addition, the structure of the lifting receiving device adopts a structure similar to that of a common lifting parking space, and the details can be referred to the prior art and will not be repeated here. In addition, the unloading blocking mechanism 430 can adopt a [-shaped rotating blocking frame 431, both ends of which can be rotatably arranged on the frame 100. At the same time, the upper end of the output rod of the driving member can be connected to at least one side end of the middle rod part of the rotating blocking frame 431, thereby driving the rotating blocking frame 431 to rotate back and forth in the vertical space, thereby blocking the product from being unloaded.

[0035] In this embodiment, the front input mechanism 210 includes a front slow conveying member 211 and a front fast conveying member 212 which are sequentially disposed on the frame 100 .

[0036] Specifically, the front slow conveyor 211 is used to slowly input the mold 600 containing the concrete product 500 and convey it to the front fast conveyor 212; the front fast conveyor 212 can quickly input the mold 600 containing the concrete product 500 into the mold turning mechanism 220, so that the distance between the front and rear molds 600 can be fully increased, so that demolding can be carried out in sequence and in an orderly manner.

[0037] In this embodiment, the front input mechanism 210 and the rear output mechanism 230 both have a plurality of first conveying parts 231 spaced apart perpendicular to the conveying direction, and the mold turning mechanism 220 has a plurality of receiving frames 221 spaced apart. In the initial state, the receiving frames 221 extend to one side of the first conveying part respectively.

[0038] Specifically, the first conveying part 231 and the receiving frame 221 are both provided in multiple numbers and are extended and cross-arranged at intervals from each other, so that the concrete product 500 can be input into the receiving frame 221 for receiving; in addition, the passive end of each first conveying part 231 is pivotally mounted using an independent short shaft.

[0039] In this embodiment, the receiving frame 221 is respectively arranged at the front and rear ends of the mold turning mechanism 220, and each end is arranged in two layers, and a baffle 222 is provided between the two layers of the receiving frame 221, which is used to accommodate the concrete product 500 mold 600 and drive it to rotate 180 degrees for mold turning.

[0040] Specifically, the receiving frame 221 is arranged in two layers and a baffle 222 is provided to accommodate the input concrete products 500. At the same time, the receiving frame 221 is arranged at the front and rear ends of the conveying direction of the mold turning mechanism 220, so that there is no need to reverse and reset after the mold is turned, and continuous operation can be carried out.

[0041] In this embodiment, the vibration demoulding mechanism 320 includes a demoulding frame 322 and an impact mechanism 323; the demoulding frame 322 is vertically movably arranged on the frame 100, and is respectively provided with a plurality of impact parts 3221 and force-bearing parts 3222; the impact part 3221 is supported by the frame 100, and the supporting part 321 is arranged on the upper part of the demoulding frame 322; the impact mechanism 323 includes a connected power mechanism 3231 and a cam 3232; the power mechanism 3231 is arranged on the frame 100, and the cam 3232 is arranged on the power mechanism 3231, and is located below the force-bearing part 3222, and is used to rotate and lift the force-bearing part 3222 and make the impact part 3221 impact on the frame 100 for demoulding.

[0042] Specifically, the demolding frame 322 is vertically movably arranged on the machine frame 100, that is, the demolding frame 322 can be vertically moved under the action of an external force. The positioning or limiting structure for this vertical movement can be respectively arranged at different positions between the demolding frame 322 and the machine frame 100 and adopt different structures. For example, matching concave-convex positioning structures or blocking and limiting structures are respectively arranged at the parts where it impacts the machine frame 100, so as to prevent the demolding frame 322 from generating obvious shaking or displacement during the movement process. Among them, a plurality of impact parts 3221, force-receiving parts 3222 and receiving parts 321 are respectively adopted. The plurality of force-receiving parts 3222 and impact parts 3221 are respectively beneficial to smoothly lift the demolding frame 322 and evenly impact and receive force. In addition, between the parts where the impact parts 3221 impact the machine frame 100, some materials that are relatively hard but have a certain elasticity, such as hard rubber and other materials, can be used. In this way, while reducing the unloading of force, damage caused by long-term hard impact can be avoided. Among them, the protruding part of the cam 3232 is used to lift the force-receiving part 3222, and its recessed part may not be in contact with the force-receiving part 3222, so as to ensure the demolding impact effect.

[0043] In this embodiment, the outer wall of the cam 3232 is provided with spaced concave parts 32321. When the impact part 3221 impacts the machine frame 100, the spaced concave parts 32321 are located below the force-receiving part 3222 and are spaced apart by a certain distance.

[0044] Specifically, when the extreme part of the convex part of the cam 3232 rotates to the force-receiving part 3222, the demolding frame 322 is lifted to the highest height. When the cam 3232 continues to rotate to the spaced concave part 32321, the demolding frame 322 moves downward through the impact part 3221 and impacts the machine frame 100. At this time, the spaced concave part 32321 is spaced from the force-receiving part 3222 without dispersing the force, so as to retain a large impact force. In addition, the spaced concave part 32321 at least includes the part of the cam 3232 located below the force-receiving part 3222 during impact. In addition, a part of the transition part between the concave part and the convex part may also belong to the spaced concave part 32321.

[0045] In this embodiment, the primary input mechanism 410 has multiple groups of second conveying parts 411 arranged at intervals along a direction perpendicular to the conveying direction; the secondary transfer platform 420 has multiple receiving platforms 421 arranged at intervals. In the initial state, the second conveying parts are respectively arranged corresponding to the intervals of the receiving platforms 421 for conveying the concrete products 500 to the receiving platforms 421. The conveying and stacking device 400 further includes a lifting mechanism 440. The lifting mechanism 440 is arranged on the machine frame 100 and is arranged on the primary input mechanism 410 or the secondary transfer platform 420 for lowering the primary input mechanism 410 or raising the secondary transfer platform 420 by a certain distance so that the concrete products 500 conveyed by the second conveying parts 411 are received on the receiving platforms 421.

[0046] Specifically, the primary input mechanism 410 is used to convey the concrete product 500 to the receiving table 421 of the secondary transfer platform 420 through the second conveying part 411. Specifically, considering the stability of receiving, adjacent second conveying parts 411 can cooperate to convey one concrete product 500. At the same time, considering the friction between the concrete product 500 and the receiving table 421 during conveying, the relative height between the two can be adjusted adaptively. For example, the conveying part is arranged slightly convex to the receiving table 421; among them, the lifting distance of the lifting mechanism 440 satisfies that the receiving table 421 is arranged to protrude from the second conveying part 411, so as to receive the concrete product 500 on the receiving table 421, thereby taking out the concrete product 500 from the second conveying part 411 and transferring it above the lifting and receiving device; among them, the lifting and receiving device can adopt the existing structure and will not be elaborated here; among them, the secondary transfer platform 420 can be received and moved through the sliding or rolling structure arranged on the frame 100, such as the receiving rollers on both inner sides of the illustrated frame 100, and at the same time, the movement is limited by the convex parts on both sides of the secondary transfer platform 420 on the frame 100; at the same time, the transfer of the secondary transfer platform 420 includes moving out above the lifting and receiving device and moving back to the second conveying part 411. When moving out above the lifting and receiving device and moving back, the concrete product 500 can be separated from the secondary transfer platform 420 and fall onto the lifting and receiving device under the blocking of the blocking and discharging mechanism 430. In addition, when the lifting mechanism 440 is arranged on the frame 100 and the primary input mechanism 410, the same ends of the two conveying shafts of the primary input mechanism 410 can be installed on a sliding seat, and the sliding seat is vertically slidably connected to the frame 100 and is lifted by other driving cylinders.

[0047] In this embodiment, the second conveying part 411 adopts the active conveying member 4111 and / or the passive conveying member 4112.

[0048] Specifically, when using a driven / passive conveying member, other pushing members and / or manual power are also required; the illustrated structure combines the active conveying member 4111 and the passive conveying member 4112. Specifically, the illustrated structure is a four-row conveying structure. Taking the concrete product 500 as an example, this structure can cooperate in pairs to convey a total of four concrete products 500 in two rows and two columns successively.

[0049] In this embodiment, when the lifting mechanism 440 is arranged on the frame 100 and the secondary transfer platform 420, the lifting mechanism 440 includes a rotating top frame 441. The rotating top frame 441 is rotatably arranged on the frame 100 and is located below the secondary transfer platform 420 for jacking up the secondary transfer platform 420 by a certain distance through rotation.

[0050] Specifically, the rotating top frame 441 is rotatably connected to the frame 100 and is arranged below the secondary transfer platform 420. It can be driven by a driving member to drive its upper end to rotate, thereby lifting the secondary transfer platform 420 for a certain distance, and then completing the reception of the concrete product 500; wherein, the rotating top frame 441 is rotatably connected to the frame 100, and the rotating connection structure itself can refer to many existing technologies and will not be repeated here.

[0051] In this embodiment, two rotating top frames 441 are used, and the two rotating top frames 441 are arranged at an interval, and a driving cylinder 442 is connected between the two to simultaneously drive the two rotating top frames 441 to rotate so as to simultaneously lift or lower the secondary transfer platform 420.

[0052] Specifically, the two rotating top frames 441 can adopt the same structure, or they can adopt a structure that is slightly different from the figure but has essentially the same operating principle; wherein, the two rotating top frames 441 can be in the structure of an inner eight as shown in the figure in the initial state, and when lifting, the two lower sections of the rotating top frames 441 are relatively close to each other through the contraction of the piston rod of the driving cylinder 442, and at the same time, the upper two sections rotate outward synchronously, thereby lifting the secondary transfer platform 420; in addition, when the two rotating top frames 441 adopt the structure of an outer eight, the above-mentioned effect can also be achieved by adopting the opposite action.

[0053] Working principle: the mold 600 containing the concrete product 500 is transported to the mold turning mechanism 220 through the front input mechanism 210. After the mold turning mechanism 220 turns the mold 600, it is output through the rear output mechanism 230 and input into the receiving part 321 of the vibration demoulding mechanism 320. The turned concrete product 500 is demoulded from the mold 600 by the vibration demoulding mechanism 320 and falls onto the demoulding conveying mechanism 310; the demoulded concrete product 500 is input to the secondary transfer platform 420 through the primary input mechanism 410. The secondary transfer platform 420 is moved out to the upper part of the lifting receiving device and blocked by the blocking unloading mechanism 430. Then the secondary transfer platform 420 is moved back to the primary input mechanism 410. During the return, the concrete product 500 is gradually blocked by the blocking unloading mechanism 430 and falls to the lifting receiving device, thereby completing a stacking.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
