[0058] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of the invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0059] Figure 1 A schematic diagram of the concrete block demolding machine is shown. Figure 2 It shows Figure 1 A structural schematic diagram of a concrete test block demolding machine from another perspective. Figure 3 A schematic diagram of the structure of the first mold 2 is shown, combined with Figures 1 to 3 The concrete test block demolding machine includes a frame 1, a trimming device 3, a first mold 2, a second mold, a first conveying device 5, a second conveying device 8, and a material ejection device 6. The trimming device 3 is mounted on the frame 1 and forms a trimming channel 31. A first position 312 is located outside the feed end 311 of the trimming channel 31, and a second position 314 is located outside the discharge end 313 of the trimming channel 31.

[0060] The first mold 2 has an opening 21 for placing a test block, and the first mold 2 has a through hole 22 on its inner bottom surface corresponding to its opening 21. The first mold 2 can serve as a mold for placing pre-set concrete test blocks. The first conveying device 5 is configured to convey the first mold 2 to the first position 312, and to position the opening 21 of the first mold 2 at the first position 312 so that it faces and communicates with the feed end 311 of the trimming channel 31.

[0061] The second mold is provided with an opening 21 for placing the test block. The second mold can place the test block after trimming and deburring, facilitate test block handling, and transfer through an external transfer component for subsequent watering and curing of the test block. The second conveying device 8 is configured to convey the second mold to the second position 314 and make the opening 21 of the second mold at the second position 314 face and communicate with the discharge end 313 of the trimming channel 31.

[0062] The first mold 2 can be placed on the transfer component and automatically fed to the first position 312 by the first conveying device 5, or directly placed on the first conveying device 5. The second mold can be placed on the transfer component and automatically fed to the second position 314 by the second conveying device 8, or directly placed on the second conveying device 8. In addition, the transfer component can be an AGV trolley.

[0063] The ejecting device 6 has an ejecting end 621 that can displace along the length direction of the trimming channel 31 from the first position 312 to the second position 314. The ejecting end 621 can penetrate into the through hole 22 and abut on the test block of the first mold 2 at the first position 312. Then the ejecting end 621 displaces and pushes the test block of the first mold 2 at the first position 312 into the trimming channel 31, so that the circumferential side wall of the test block is trimmed by the trimming channel 31, and then the test block is pushed into the second mold at the second position 314.

[0064] Specifically, when the test block needs to be demolded, the concrete test block demolding machine aligns the opening 21 of the first mold 2 with the inlet end 311 of the trimming channel 31 through the first conveying device 5, aligns the opening 21 of the second mold with the trimming channel 31 and the discharge end 313 through the second conveying device 8, and then pushes the test block in the first mold 2 out and into the second mold after trimming through the trimming channel 31. The inner wall of the trimming channel 31 is in close contact with the outer shape of the test block, so that the test block can remove the burrs and flash on the side of the test block under the action of friction when passing through the trimming channel 31.

[0065] The concrete test block demolding machine can realize the trimming and transfer functions of the test block during the demolding process of the concrete test block, save the process, reduce the handling process, improve the production efficiency, and make the side of the test block more flat after trimming, which can reduce the stress error of the subsequent pressure quality detection and improve the standardization degree of the test block.

[0066] As Figure 1As shown, the bottom of the rack 1 is provided with a plurality of casters 11, so that the concrete block demolding machine can be moved, facilitating flexible use by the user. In addition, the lower part of the outer periphery of the rack 1, above the corresponding casters 11, is provided with a guide mechanism 12, which can be a horizontal slot that can conveniently position the loading of a plurality of first molds 2 and the loading of a plurality of second molds to the corresponding working positions, respectively. The guide mechanism 12 can provide position assistance adjustment for the transfer component.

[0067] As shown, Figure 3 The first mold 2 is provided with three openings 21 arranged in sequence and spaced apart, and the inner bottom surface of the opening 21 is provided with a through hole 22 for the extension of the ejector end 621. The structure of the second mold can refer to the structure of the first mold 2, and correspondingly provided with the same number of openings 21, so that the test block is one-to-one received in the second mold. In actual work, the number and position of the openings 21 on the first mold 2, the number and position of the feeding end 311 of the trimming channel 31, and the number and position of the ejector end 621 are one-to-one corresponding. The number and position of the openings 21 on the second mold correspond to the number and position of the discharge end 313 of the trimming channel 31. In addition, the first mold 2 can also be provided with only one or more openings 21.

[0068] Figure 4 The structure of the trimming frame 32 is shown in the structure diagram of the trimming channel 31 discharge end 313, Figure 5 The trimming frame 32 is shown in the cross-sectional view along the direction of the plurality of trimming channels 31. Referring to Figure 4 And Figure 5 The trimming frame 32 is arranged on the rack 1, and the trimming frame 32 encloses at least one trimming channel 31, and the two ends of the trimming channel in the axial direction are respectively the feeding end 311 and the discharge end 313. The position corresponding to the feeding end 311 is the first position 312. The position outside the discharge end 313 is the second position 314. The trimming frame 32 is provided with a trimming portion 315 at a position corresponding to the trimming channel 31, and the trimming portion 315 is protruded relative to the inside of the trimming channel 31.

[0069] Specifically, the first die 2 at the first position 312 abuts against the end face of the trimming frame 32 facing the first position 312, the second die at the second position 314 abuts against the end face of the trimming frame 32 facing the second position 314, and the inner wall of the trimming channel 31 is in shape fitting and one-to-one correspondence with the outer wall of the test block. By providing the trimming part 315 on the inner wall of the trimming channel 31 corresponding to the trimming frame 32, the test block passing through the trimming channel 31 can be removed burr under the action of the protruding trimming part 315, and then further remove the small burr fitting the inner wall of the trimming channel 31, improve the trimming effect of the test block. In the embodiment, the test block is square, and the cross-sectional shape of the trimming channel 31 can be square, that is, it has four inner side walls connected in sequence. It should be noted that the protruding position of the trimming part 315 can always ensure that the test block can smoothly pass through the trimming channel 31.

[0070] The trimming part 315 can be located at the inlet end 311 of the trimming channel 31 or at a position other than the two ends of the trimming channel 31. The trimming part 315 is provided on at least one inner side wall of the trimming channel 31, and can be provided on one, two or more inner side walls of the trimming channel 31. The trimming part 315 can be strip-shaped or sheet-shaped protrusion. If the trimming part 315 is strip-shaped, the trimming part 315 can extend perpendicular to the length direction of the trimming channel 31, or at an angle to the length direction of the trimming channel 31. In addition, the strip-shaped trimming part 315 can be in a straight line, a broken line, an arc or a wavy line structure, and the embodiment does not specifically limit the specific shape, position and layout of the trimming part 315.

[0071] Further, the trimming frame 32 includes a plurality of partitions 323, a first side plate 321 and a second side plate 322 oppositely arranged, the partitions 323 are connected between the first side plate 321 and the second side plate 322, and a plurality of the partitions 323 are arranged in sequence. The adjacent two partitions 323, the first side plate 321 and the second side plate 322 form the trimming channel 31.

[0072] Specifically, the plate structure is used to form the square trimming channel 31, the length direction of the trimming channel 31 extends in a straight line, the inner wall of the trimming channel 31 fits the outer side wall of the test block, and the trimming effect of the test block is improved. A plurality of trimming channels 31 are arranged in sequence in the same direction and correspond to the positions of the openings 21 of the first die 2 and the second die.

[0073] In addition, the trimming channel 31 formed by the trimming frame 32 extends in a horizontal direction. Specifically, the first side plate 321 and the second side plate 322 can both be arranged in the horizontal direction and are arranged in a vertical direction. In some other embodiments, the first side plate 321 and the second side plate 322 can both be arranged in a vertical direction and are arranged in a horizontal direction. In addition, the trimming channel 31 can also be arranged in an angle direction relative to the horizontal direction. However, the trimming channel 31 is generally not arranged in a vertical direction to prevent the test block in the first mold 2 or the test block on the second mold from directly falling into the trimming channel 31 under the action of gravity. If the trimming channel 31 is arranged in a vertical direction or a relatively inclined direction, a moving member for bearing and moving the test block needs to be additionally arranged on the trimming channel 31.

[0074] The first side plate 321, the second side plate 322, and the partition plate 323 can be connected by welding or formed by sheet metal bending.

[0075] Further, Figure 6 For the structure of the trimming frame 32 in the embodiment, the trimming frame 32 further includes a trimming strip 325 connected between the first side plate 321 and the second side plate 322. The trimming strip 325 is arranged on one side of the partition plate 323 close to the first position 312. The trimming strip 325 extends into the interiors of two adjacent trimming channels 31 from the opposite sides.

[0076] Specifically, the number of the trimming strips 325 corresponds to the number of the partition plates 323. The first direction is the arrangement direction of the plurality of trimming channels 31. The thickness of the trimming strip 325 in the first direction is greater than the thickness of the partition plate 323 in the first direction. The opposite sides of the trimming strip 325 in the first direction can protrude into the two adjacent trimming channels 31. The trimming strip 325 in the embodiment is the trimming part 315.

[0077] In the embodiment, the trimming channel 31 surrounded by the trimming frame 32 extends in the horizontal direction, and the trimming strips 325 extend in the vertical direction, so that each trimming channel 31 forms protrusions on the opposite sides in the horizontal direction at the feeding end 311. The trimming strips 325 on the two sides can remove burrs on the two horizontally opposite pressure surfaces of the test block, and then further remove the burrs that have fallen off through the inner wall of the trimming channel 31, so that the two horizontally opposite pressure surfaces of the test block are flattened. After the two pressure surfaces of the test block are trimmed, the positions of the pressure surfaces need to bear the pressure of the pressure testing machine in the subsequent pressure testing process, and need to be completely attached to the anvil plate of the pressure testing machine. The trimming of the pressure surfaces can make the stress of the pressure surfaces more uniform, improve the standardization of the test block, and reduce the stress error of the pressure quality testing. After the two opposite pressure surfaces of the test block are extruded, the remaining free surfaces of the test block will be broken, and the worker can observe the cracks on the test block through the camera to judge the stress strength of the test block.

[0078] In order to improve the positioning stability of the first mold 2 in the first position 312 and the second mold in the second position 314, and ensure that the test block can be smoothly demolded from the first mold 2 and enter the second mold through the trimming frame 32, in some embodiments, a first supporting piece 33 is arranged on one side of the trimming frame 32 close to the first position 312. A second supporting piece 34 is arranged on one side of the trimming frame 32 close to the second position 314. The first supporting piece 33 can be used to support the first mold 2 located in the first position 312 to keep the first mold 2 stable. The second supporting piece 34 can be used to support the second mold located in the second position 314 to keep the second mold stable.

[0079] The first supporting piece 33 and the second supporting piece 34 can be selected as a rod, a block or a plate, etc., as long as the first supporting piece 33 can at least position or limit the bottom or the horizontally opposite two sides of the first mold 2, and the second supporting piece 34 can at least position or limit the bottom or the horizontally opposite two sides of the second mold.

[0080] Further, the first supporting piece 33 in the embodiment includes two first supporting plate units 331 arranged in the horizontal direction. The two first supporting plate units 331 are arranged in a staggered manner with the first transfer mechanism 51 on the first conveying device 5, so as to reduce the interference between the devices.

[0081] Specifically, the two first supporting plate units 331 can be arranged on the bottoms on the opposite sides of the first position 312 in the first direction, and then can be respectively supported on the bottoms on the opposite sides of the first mold 2 in the first direction located in the first position 312.

[0082] In some embodiments, the first supporting plate unit 331 comprises bottom edge plates and side edge plates arranged in a staggered manner. The bottom edge plates extend horizontally and can support the bottom surface of the first mold 2. The side edge plates extend vertically and can limit the movement of the first mold 2 in the first direction. In this way, the positioning of the first mold 2 in the height direction and the limiting of the first mold 2 in the first direction are simultaneously achieved. In practice, the bottom edge plates and the side edge plates can be arranged separately or connected to each other to form an L-shaped structure.

[0083] In addition, the first supporting plate unit 331 is gradually expanded at the opening 21 on the side corresponding to the entering direction of the first mold 2, so as to guide the first mold 2 and facilitate the alignment and entering of the first mold 2. Specifically, when the first mold 2 enters the first position 312 from top to bottom, the side edge plates on the two supporting plate units are inclined upward and away from each other. When the first mold 2 enters the first position 312 horizontally, the side edge plates on the two supporting plate units extend away from the trimming frame 32 and away from each other.

[0084] The second supporting member 34 in the embodiment comprises two second supporting plate units 341 arranged in a horizontal direction, which can reduce interference with the first conveying device 5 and the like. In addition, the structure of the second supporting plate unit 341 can refer to the description of the first supporting plate unit 331 above, and can also be an L-shaped plate structure, which will not be described here.

[0085] Referring to Figure 7 The first conveying device 5 comprises a first transfer mechanism 51, which comprises a first supporting platform 511 capable of supporting the first mold 2 and driving the first mold 2 to flip 90° and reset, so that the first mold 2 with the opening 21 upward on the first supporting platform 511 can be flipped to the first position 312. Specifically, the trimming channel 31 extends in the horizontal direction. Correspondingly, the feeding end 311 and the discharging end 313 of the trimming channel 31 are both open to the horizontal direction. The first mold 2 with the opening 21 upward is loaded on the first supporting platform 511, the first mold 2 is positioned and supported by the first supporting platform 511, and the first mold 2 is flipped, so that the first mold 2 can be flipped from the state with the opening 21 upward to the state with the opening 21 horizontal, and then enter the first position 312, at this time the opening 21 of the first mold 2 faces the feeding end 311 of the trimming channel 31. The test block is initially solidified in the first mold 2 with the opening 21 upward, the first mold 2 is flipped 90° by the first conveying device 5, so that the solidified test block can be demolded from the first mold 2 under the action of the ejecting end 621 and then enter the trimming channel 31 for trimming and then enter the second mold with the opening 21 also facing the horizontal direction. In addition, the first transfer mechanism 51 can also drive the first mold 2 to flip 180° or other angles.

[0086] In addition, the first conveying device 5 can also be a conveying belt, a pushing member capable of pushing the first mold 2, or an up-down conveying member capable of moving the first mold 2 up and down, etc., and the opening 21 of the first mold 2 always keeps unchanged during the process of being brought to the first position 312 from the first conveying device 5.

[0087] The first supporting platform 511 for supporting part of the first mold 2 can be a flat plate or a block arranged on the bottom of the opposite sides of the first mold 2, etc. When the first supporting platform 511 supports the first mold 2 with the opening 21 upward, the supporting surface of the first supporting platform 511 in contact with the first mold 2 is upward, and when the first supporting platform 511 supports the first mold 2 with the opening 21 toward the feeding end 311 of the trimming channel 31, the supporting surface of the first supporting platform 511 is also toward the feeding end 311 of the trimming channel 31.

[0088] Further, the first conveying device 5 comprises the first supporting platform 511, a rotating driving member 512 and at least one rotating arm 513, the output end of the rotating driving member 512 is synchronously connected to one end of the rotating arm 513, and the first supporting platform 511 is synchronously arranged at the other end of the rotating arm 513. The rotating arm 513 swings under the action of the rotating driving member 512, so that the first supporting platform 511 can realize large-amplitude position switching, thereby driving the first mold 2 to be conveyed for a certain distance, and the first mold 2 can be switched back and forth between the feeding position and the first position 312 of the concrete test block stripping machine under the action of the first conveying device 5. The rotating arm 513 can be provided with two, which improves the connection stability of the first supporting platform 511.

[0089] In addition, the first conveying device 5 can also be a conveying belt, a pushing member capable of pushing the first mold 2, or an up-down conveying member capable of moving the first mold 2 up and down, etc., and the opening 21 of the first mold 2 always keeps unchanged during the process of being brought to the first position 312 from the first conveying device 5.

[0090] In order to improve the positioning stability of the first mold 2 on the first supporting platform 511, the first supporting platform 511 is provided with a baffle 514 on the opposite sides of the rotating direction, the baffle 514 extends and protrudes from the first supporting platform 511 in a direction away from the rotating arm 513, and the limiting space 515 capable of positioning the first mold 2 is formed between the baffle 514 on the two sides and the first supporting platform 511.

[0091] Specifically, the baffle 514 includes a first baffle 514 and a second baffle 514, which are respectively arranged on the opposite sides of the first supporting platform 511 towards the rotating direction. During the process of turning the first mold 2 with the opening 21 upwards to the first position 312 by the first supporting platform 511, the first baffle 514 can block the first mold 2 from falling under the action of gravity, and the first baffle 514 can support the bottom of the first mold 2 located at the first position 312. When the first supporting platform 511 turns the first mold 2 at the first position 312 back to the position with the opening 21 upwards, the baffle 514 on the other side can block the first mold 2 from falling out of the first supporting platform 511 under the action of inertia, and the first mold 2 can be kept positioned in the limiting space 515, so that the first transferring mechanism 51 can continuously switch the position of the first mold 2.

[0092] In some specific embodiments, the extension length of the second baffle 514 away from the rotating arm 513 is less than the extension length of the first baffle 514 away from the rotating arm 513, which facilitates the staff or other automatic feeding structure to feed the first mold 2 to the first supporting platform 511, and reduces interference. Moreover, the first baffle 514 and the second baffle 514 can be respectively an integral plate or composed of plate pieces arranged at intervals.

[0093] In combination with Figure 7 and Figure 8 , the end surface of the first supporting platform 511 is provided with a protrusion 516 corresponding to the shape and position of the through hole 22, and the protrusion 516 is provided with a guide hole 5161, wherein: when the first mold 2 is located at the first position 312, the ejector end 621 can pass through the guide hole 5161 and enter the through hole 22.

[0094] Specifically, when the first mold 2 is placed on the first supporting platform 511, the protrusion 516 enters the through hole 22 of the first mold 2, and the guide hole 5161 communicates with the through hole 22. When the first mold 2 is located at the first position 312, the ejector end 621 of the ejecting device 6 can pass through the guide hole 5161 and enter the through hole 22, and can pass through the through hole 22 and abut against the test block in the first mold 2. The number of the protrusions 516 matches the number of the through holes 22 of the first mold 2.

[0095] In some specific embodiments, the opening 21 of the guide hole 5161 near one end of the rotating arm 513 is gradually expanded, which plays a guiding role for the ejector end 621 and facilitates the entry of the ejector end 621. The outer diameter of the protrusion 516 away from one end of the rotating arm 513 is gradually reduced, which facilitates the entry of the protrusion 516 into the through hole 22 of the first mold 2.

[0096] Referring to Figure 9 and Figure 10, the first conveying device 5 further comprises a first clamping mechanism 52, which is used for clamping the first mold 2 with the test block to the first supporting platform 511 or taking the empty first mold 2 out of the first supporting platform 511. The first mold 2 can be automatically fed to the first supporting platform 511.

[0097] Further, the first clamping mechanism 52 comprises a clamping jaw 521, a switching platform 522, a first driving member 523 and a second driving member 524. The clamping jaw 521 can grab or release the first mold 2. The switching platform 522 is staggered with the first supporting platform 511. The driving end of the first driving member 523 is connected to the clamping jaw 521, and the first driving member 523 is configured to move the clamping jaw 521 to the upper side of the switching platform 522. The driving end of the second driving member 524 is connected to the switching platform 522, and the second driving member 524 is configured to move the switching platform 522 up and down, so that the switching platform 522 can transfer the first mold 2 on the clamping jaw 521 to the first supporting platform 511.

[0098] Specifically, after the clamping jaw 521 grabs the first mold 2, the first driving member 523 moves the clamping jaw 521 to the upper side of the switching platform 522. The switching platform 522 is moved up to the bottom of the first mold 2 under the action of the second driving member 524, and is higher than the height of the first supporting platform 511. The clamping jaw 521 releases the first mold 2, so that the first mold 2 is placed on the switching platform 522. Then, the second driving member 524 drives the switching platform 522 to move down and switch the first mold 2 to the first supporting platform 511. The switching platform 522 can stably transfer the first mold 2 on the clamping jaw 521 to the first supporting platform 511, avoiding the situation that the first mold 2 shakes and suddenly falls after the clamping jaw 521 releases, and protecting the integrity of the first mold 2 and the test block.

[0099] Conversely, after the test block in the first mold 2 is demolded, the first transfer device flips the first supporting platform 511 to reset, and then lifts the first mold 2 to a place where the clamping jaw 521 can be clamped by the switching platform 522, so that the clamping jaw 521 moves the first mold 2 out under the action of the first driving member 523. The clamping jaw 521 can be formed by two clamping arms that can relatively move away and close to each other through a clamping jaw 521 cylinder or a linear driving member such as a cylinder. The first driving member 523 and the second driving member 524 are arranged on the rack 1, and can be driving devices such as cylinders, motor lead screws, etc.

[0100] It should be noted that, as Figure 10As shown, the switching platform 522 is staggered with the first supporting platform 511 in the up-down direction, so that the switching platform 522 can avoid the position of the first supporting platform 511 during the up-down displacement. In addition, the first supporting platform 511 does not completely cover the bottom surface of the first mold 2, so that the switching platform 522 can face the part of the bottom surface of the first mold 2 upwards, and the switching platform 522 can stably take the first mold 2 from the clamping jaw 521 or the first supporting platform 511.

[0101] In the embodiment, two switching platforms 522 are arranged, and the two switching platforms 522 are arranged on opposite sides of the first supporting platform 511. Specifically, the two switching platforms 522 are arranged on the two sides of the first supporting platform 511 along the first direction.

[0102] With reference to Figure 11 , the material ejecting device 6 comprises a third driving member 61 and a ejector pin 62. The third driving member 61 is arranged on the rack 1, and the ejector pin 62 is synchronously connected to the output end of the third driving member 61 and can reciprocally displace along the length direction of the trimming channel 31. The ejector pin 62 extends towards the direction close to the trimming device 3, and the end of the ejector pin 62 close to the trimming device 3 is the material ejecting end 621.

[0103] The ejector pin 62 extends towards the material inlet end 311 of the trimming channel 31. In the embodiment, the ejector pin 62 extends horizontally. The three ejector pins 62 are arranged in sequence and at intervals along the first direction, and correspond to the three material inlet ends 311 of the three trimming channels 31 in the trimming frame 32 respectively.

[0104] With reference to Figure 1 , the third driving member 61 is arranged on the rack 1, and the third driving member 61 can be a telescopic air cylinder or a motor lead screw.

[0105] In combination Figure 1 and Figure 12 , the concrete test block stripping machine further comprises a waste collecting bin 7 arranged on the rack 1 and below the trimming device 3, for collecting the residual material of the test block after trimming by the trimming device 3. The waste collecting bin 7 has an opening 21 facing upwards, and the inner bottom surface of the waste collecting bin 7 extends obliquely downwards, so that the residual material can be guided out of the equipment. In addition, a material blowing structure can be arranged on the rack 1, so that the debris in the trimming channel 31 corresponding to the trimming frame 32 can be blown into the waste collecting bin 7.
