Description

Technical Field

[0001] This invention relates to the field of cement production technology, and in particular to an automatic demolding device for cement strength testing. Background Technology

[0002] In industries that produce powdered or granular materials, such as cement and building materials, it is necessary to sample and retain materials from different production stages for analysis to control production quality. For example, in the cement industry, cement strength is one of the core indicators for evaluating product quality. Cement strength testing requires mixing cement and standard sand in a fixed ratio to form mortar test blocks, which are then cured, demolded, and subjected to compressive or flexural strength tests. The demolding process is a preliminary step in the testing process, and its standardized operation directly affects the reliability of the subsequent strength test results of the cement test blocks.

[0003] Most cement plants still use manual methods to remove cement test blocks, which is not only inefficient but also labor-intensive. The force, angle, and timing of removal by each operator depend entirely on their experience, resulting in significant differences in techniques among different operators. This makes it impossible to achieve uniformity in the removed cement test blocks, which can easily lead to errors in subsequent test results. Therefore, an automatic demolding device for cement strength testing is proposed. Summary of the Invention

A push hook block is connected to the movable end of the control cylinder, which can be used to push the cement mold forward and hook it back. Both sides of the demolding template are rotatably connected to the pawls via pins. Blocking cylinders are installed on both sides of the demolding template. The movable end of each blocking cylinder is rotatably connected to the pawl via a pin. A rotating frame is rotatably connected to the end of the demolding template near the limiting blocks.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Reference Figure 1-11 As shown, an automatic demolding device for cement strength testing includes a support frame 1, a handling component 2, a transfer component 3, a demolding component 4, a demolding component 5, and an electrical control box 7. The transport assembly 2 is installed on the top of the support 1 and is used to transport the cement mold 6 to different work stations for demolding. The transfer component 3 is installed at one end of the bracket 1 and is used to position the cement mold 6 in preparation for handling; The demolding assembly 4 is installed in the middle of the bracket 1 and is used to demold the cement mold 6. The demolding assembly 5 is installed at the other end of the bracket 1 and is used to remove the cement test block from the cement mold 6; The electrical control box 7 is electrically connected to the control circuits of the transport component 2, transfer component 3, demolding component 4, and demolding component 5 via wires.

[0030] The cement mold 6 used in the automatic demolding equipment of this invention is as follows: Figure 6As shown, the cement mold 6 consists of an upper mold 61 and a lower mold 62. One end of the lower mold 62 is rotatably connected to a rotating shaft 63. Two symmetrical eccentric wheels 64 are connected to the rotating shaft 63. Multiple through holes 66 are opened in the middle of the rotating shaft 63. The upper mold 61 is connected to a stop block 65. Guide strips 67 are connected to the outer mold walls on both sides of the upper mold 61. During mold making, the thickest wheel surface of the eccentric wheel 64 faces the stop block 65. By pressing the stop block 65, the upper mold 61 and the lower mold 62 are tightly combined.

[0031] In this embodiment, the conveying assembly 2 includes two movable plates 22. The top of the support 1 is equipped with two parallel slide rails 21. The bottom of each movable plate 22 is connected to two pairs of first sliders 211. The two pairs of first sliders 211 are slidably connected to the two slide rails 21 respectively. The top of the support 1 is equipped with a first rack 23. The bottom of each movable plate 22 is equipped with a first motor 231. The output shaft of the first motor 231 is coaxially connected with a first gear 232. Both first gears 232 mesh with the first rack 23. The bottom of each movable plate 22 is equipped with a lifting cylinder 24. The movable end of the lifting cylinder 24 is connected to a mounting frame 25. The mounting frame 25 is equipped with a clamping unit.

[0032] In this embodiment, the clamping unit includes a floating centering device 26, which is mounted on the mounting frame 25. The floating centering device 26 is a mechanical device used to automatically adjust its position or attitude to achieve precise centering or alignment, compensating for positional deviations in real time when gripping the cement mold 6. A guide member 261 is connected to the top of the floating centering device 26. Figure 5 As shown, the guide component 261 matches the guide strip 67 of the cement mold 6, enabling precise positioning when gripping the cement mold 6. The top of the guide component 261 is connected to a gripper cylinder 27, and both movable ends of the gripper cylinder 27 are connected to grippers 28. The side of the mounting frame 25 is equipped with a first air knife 29. During the handling of the cement mold 6, the first air knife 29 is activated to quickly remove moisture from the surface of the cement test block inside the cement mold 6 through directional high-pressure airflow, providing a reliable guarantee for the subsequent demolding process.

[0033] In this embodiment, each gripper 28 consists of two hooks 281. The hooks 281 on the grippers 28 below the two moving plates 22 are spaced at different intervals. The gripping unit below the moving plate 22 near the right end is only responsible for transporting the cement mold 6 on the transfer component 3 to the demolding station of the demolding component 4. The width of the two hooks 281 on the gripper 28 is greater than the width of the guide bar 67. During transport, the hooks 281 extend into the bottom of the lower mold 62 to transport the entire cement mold 6. The gripping unit below the moving plate 22 near the left end is only responsible for transporting the disassembled upper mold 61 and its cement test block from the demolding station of the demolding component 4 to the demolding station of the demolding component 5. The width of the two hooks 281 on the gripper 28 is less than the width of the guide bar 67. During transport, the hooks 281 extend into the bottom of the guide bar 67 to transport the upper mold 61.

[0034] In this embodiment, the transfer assembly 3 includes a transfer plate 31, which is slidably connected to the bracket 1. The sliding direction of the transfer plate 31 is perpendicular to the slide rail 21. A second motor 32 is mounted on the bracket 1. A second gear 321 is coaxially connected to the output shaft of the second motor 32. A second rack 322 is connected to the transfer plate 31. The second gear 321 meshes with the second rack 322. Two placement platforms 33 are connected to the transfer plate 31. A transverse positioning cylinder 34 is installed on the transfer plate 31 and located in the middle of the two placement platforms 33. Both movable ends of the transverse positioning cylinder 34 are connected to push rods 35. Two positioning blocks 36 are connected to the side of each placement platform 33 away from the transverse positioning cylinder 34. The transverse position of the cement mold 6 on the placement platform 33 can be adjusted by the positioning blocks 36 and the transverse positioning cylinder 34, which facilitates the clamping and handling by the transport assembly 2.

[0035] In this embodiment, a longitudinal positioning cylinder 37 is installed at the bottom of each placement platform 33. The movable end of the longitudinal positioning cylinder 37 is connected to an L-shaped push block 371. The placement platform 33 is only provided with a push block 371 on the side near the second motor 32. This is so that when the robotic arm transfers the cement mold 6 to the placement platform 33, when the entire cement mold 6 is tilted towards the side of the second motor 32, the gripper 28 of the moving plate 22 below the extreme position of the rightmost end of the slide rail 21 will have a vertical deviation from the cement mold 6. The longitudinal positioning cylinder 37 and the push block 371 need to be able to push the cement mold 6 back onto the placement platform 33 to ensure that the gripper 28 of the transport component 2 can clamp it. The reason why the other side of the placement platform 33 is not provided is that even if the cement mold 6 is tilted to the other side, the gripper 28 can clamp the tilted cement mold 6 by moving the moving plate 22 on the slide rail 21.

[0036] In this embodiment, the demolding assembly 4 includes a fixed frame 41 and a rotating motor 47. The fixed frame 41 is installed in the middle of the support 1. A demolding template 42 is connected to the top of the fixed frame 41. Two symmetrical limiting blocks 43 are connected to one end of the demolding template 42. A control cylinder 44 is installed at the end of the demolding template 42 away from the limiting blocks 43. A push hook block 441 is connected to the movable end of the control cylinder 44 for pushing the cement mold 6 forward and hooking the lower mold 62 back. Both sides of the demolding template 42 are rotatably connected to the blocking claws 45 by pins. Blocking cylinders 451 are installed on both sides of the demolding template 42. The movable end of each blocking cylinder 451 is rotatably connected to the blocking claw 45 by a pin. Here, the diameter of the pin groove on the blocking claw 45 is larger than the diameter of the pin, ensuring that the blocking cylinder 451 extends... When retracted, the rotation of the stop 45 is not affected. The end of the demolding template 42 near the limiting block 43 is rotatably connected to a rotating frame 46. The rotating motor 47 is mounted on the bracket 1 to drive the rotating frame 46 to rotate. Two sliding rods 48 are slidably connected to both sides of the rotating frame 46. The lower ends of the two sliding rods 48 are connected to a base plate 481. A demolding cylinder 49 is installed on the base plate 481. The movable end of the demolding cylinder 49 passes through the base plate 481 and is connected to the rotating frame 46. The upper ends of the two sliding rods 48 are connected to an insert rod 482. The shape of the upper end of the insert rod 482 matches the insertion hole 66 on the rotating shaft 63 of the cement mold 6. A demolding opening 421 is opened at the end of the demolding template 42 near the limiting block 43. The design of the demolding opening 421 is to provide space for the rising and rotating of the insert rod 482.

[0037] In this embodiment, the demolding assembly 5 includes a mounting plate 51, a translation plate 54, and a demolding blade 56. The mounting plate 51 is connected to the bracket 1. Multiple protrusions 52 are connected to the mounting plate 51. The shape and size of the protrusions 52 are similar to those of the cement test blocks. The gap between any two adjacent protrusions 52 is slightly larger than the thickness of the partition separating the cement test blocks in the upper mold 61. The overall shape of the demolding blade 56 matches that of the upper mold 61. Four locking rods 53 are connected to the mounting plate 51 on both sides of the protrusions 52. An adjusting cylinder 58 is mounted on the mounting plate 51. The movable end of the adjusting cylinder 58 is connected to a push plate 581. The bottom of the translation plate 54... Two pairs of second sliders 541 are connected, and the two pairs of second sliders 541 are slidably connected to two slide rails 21 respectively. A third motor 542 is installed at the bottom of the translation plate 54. The output shaft of the third motor 542 is coaxially connected to a third gear 543. The third gear 543 meshes with the first rack 23. A lifting motor 55 is installed at the bottom of the translation plate 54 to control the lifting and lowering of the demolding knife 56. A second air knife 57 is installed on the side of the demolding knife 56. During the horizontal movement of the demolding knife 56, the second air knife 57 is opened to quickly remove the moisture on the surface of the cement test block inside the cement mold 6 through directional high-pressure airflow, providing a reliable guarantee for the subsequent demolding process.

[0038] In this embodiment, multiple push rods 591 are slidably connected through the mounting plate 51. The multiple push rods 591 are distributed in the gap between the two protrusions 52 and the gap between the protrusions 52 and the locking rod 53. The lower ends of the multiple push rods 591 are connected to a connecting plate 592. A lifting cylinder 59 is installed on the bottom surface of the connecting plate 592. The movable end of the lifting cylinder 59 passes through the connecting plate 592 and is connected to the bottom of the mounting plate 51. The multiple push rods 591 rise before demolding to support the upper mold 61, preventing the upper mold 61 from being suspended in the air during demolding and falling rapidly after the upper mold 61 separates from the cement test block, thus further ensuring the stability of demolding.

[0039] The working process and principle of this invention are as follows: Step 1: The robotic arm first transfers the cured cement mold 6 to the placement platform 33 of the transfer component 3, and then activates the horizontal positioning cylinder 34 and the vertical positioning cylinder 37 to adjust the position of the cement mold 6 to be positioned and aligned with the placement platform 33. Step 2: Turn on the first motor 231 on the right-hand moving plate 22. Control the moving plate 22 to slide to the rightmost end of the slide rail 21 through gear and rack meshing. Then turn on the lifting cylinder 24 to control the clamping unit to descend. During the descent of the clamping unit, the guide 261 first contacts the guide strip 67 on the cement mold 6. The floating centering device 26 compensates for the position deviation. Then turn on the gripper cylinder 27. The gripper 28 hooks the cement mold 6 on the placement platform 33. Then the cement mold 6 is transported to the demolding station of the demolding assembly 4 (i.e., the demolding template 42). Step 3: First, activate the control cylinder 44 to move the cement mold 6 on the demolding template 42 to abut against the limit block 43. Then, activate the demolding cylinder 49 to move the insertion rod 482 upward and insert it into the insertion hole 66 of the rotating shaft 63 on the cement mold 6. Next, activate the rotating motor 47 to move the entire rotating frame 46, causing the insertion rod 482 to rotate the rotating shaft 63, loosening the eccentric wheel 64. The demolding cylinder 49 then pulls the insertion rod 482 out of the insertion hole 66, releasing the tightness. After that, the control cylinder 44 pulls the lower mold 62 back. When it slides back to a certain point... After positioning, the control cylinder 451 extends, causing the pawl 45 to rotate and press against the lower mold 62 (the protruding area of ​​the lower mold 62 near the block 65). Then, the control cylinder 44 continues to pull the lower mold 62 back, causing a lateral displacement difference between the upper mold 61 and the lower mold 62, thus separating the upper mold 61 and the lower mold 62. The clamping unit of the left-side moving plate 22 is then controlled to clamp the upper mold 61 and transport the upper mold 61 and the cement test block inside it to the demolding station of the demolding component 5 (on the protruding block 52), and the demolding is completed. Step 4: After transportation, the upper mold 61 is placed on the protrusion 52 and positioned between the four clamping rods 53. The adjusting cylinder 58 is activated to push the upper mold 61 so that the gap between the upper mold 61 and the protrusion 52 corresponds. Then, the lifting cylinder 59 is activated to control the lifting rod 591 to rise and support the bottom of the upper mold 61. At the same time, the third motor 542 is driven to move the translation plate 54 on the slide rail 21, so that the demolding knife 56 moves to the position directly above the upper mold 61. The lifting motor 55 controls the demolding knife 56 to descend to the upper surface of the upper mold 61. Then, the demolding knife 56 is controlled to descend and push the upper mold 61. Due to the support of the protrusion 52, the cement test block separates from the upper mold 61 and the cement test block inside, completing the demolding. After the cement test block is removed, the lifting cylinder 591 is controlled to push the lifting rod 591 to rise and push the upper mold 61 out, which facilitates the subsequent demolding of the cement test block.
