Description

Technical Field

[0001] The invention relates to the technical field of cleaning prefabricated component molds, and in particular discloses a small-sized prefabricated component mold cleaning device. Background Art

[0002] Small prefabricated components are concrete products frequently used in the fields of construction, transportation, water conservancy, etc. During their production and preparation, molds of corresponding shapes and sizes are used, and then they are processed and produced in a standardized and mechanized manner. For example, some common small prefabricated panels pour concrete into corresponding plastic molds during the processing, and separate them from the molds after they are solidified and formed. The separated molds need to be cleaned accordingly before they can be put into use again. At present, the existing small prefabricated component molds are cleaned by hand-held spraying to flush the molds with flushing liquid, and then placed on a rack to drain the water after flushing. The above whole process not only causes serious waste of water resources, but also some molds have uneven application of release agents before pouring. After the prefabricated parts are demolded, some impurities will remain on the inner wall of the mold. It is impossible to clean them only by flushing with flushing liquid, which affects the subsequent reuse of the mold.

[0003] The utility model patent with application number 201921152857X discloses a cleaning system for cleaning molds for building prefabricated components, which includes a cleaning conveyor line and a return conveyor line. The cleaning conveyor line and the return conveyor line are arranged in parallel, and the cleaning conveyor line and the return conveyor line are connected by a transverse ferry line. The cleaning conveyor line is provided with high-pressure cleaning equipment and an air drying bin, and the discharge end of the cleaning conveyor line is connected with the feed end of the return conveyor line by a transverse ferry line. During operation, the utility model uses a conveyor line to carry out directional transportation of the mold, and then uses high-pressure water to rinse the mold during the transportation process. Although it realizes the assembly line cleaning operation of the mold and improves the efficiency of cleaning the mold, it wastes water resources seriously, and it is unable to wash away some impurities adhering to the inner wall, resulting in the inner wall of the mold not being cleaned cleanly. In view of the above-mentioned deficiencies of the existing cleaning system for cleaning molds for building prefabricated components, this application proposes a small prefabricated component mold cleaning device that can effectively solve the above technical problems.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 8 , and describes the application in detail with reference to embodiments. Example 1

[0032] Example 1 discloses a cleaning device for a small prefabricated component mold, see attached Figure 1 , Attachment Figure 2 and attached Figure 3The main body of the cleaning equipment includes a chassis 1, a control cabinet 2 and a spray unit 3. A feed seat 101 and a discharge seat 102 are respectively connected to the openings at the left and right ends of the chassis 1, and a row of conveying rollers 100 are arranged in the chassis 1 and the feed seat 101 and the discharge seat 102, so that the small prefabricated component mold is placed in the feed seat 101, and then conveyed from left to right under the action of the conveying rollers 100, and finally sent out from the discharge seat 102.

[0033] Reference Figure 3 The spray unit 3 includes a first spray pipe 301 disposed at the upper left end of the inner cavity of the chassis 1. The first spray pipe 301 is disposed perpendicular to the conveying direction, and a plurality of spray heads 302 are disposed at intervals at the lower end of the first spray pipe 301. A second spray pipe 303 is disposed at the lower right end of the inner cavity of the chassis 1. The second spray pipe 303 is also disposed perpendicular to the conveying direction, and a plurality of spray heads 302 are also disposed at intervals at the upper end of the second spray pipe 303. Then, the first spray pipe 301 and the second spray pipe 303 are extended out of the chassis and connected to the corresponding high-pressure water source. When the mold to be cleaned enters the interior of the chassis 1, the cleaning liquid is first sprayed toward the interior of the mold through the spray head 302 on the first spray pipe 301 to rinse and moisten it; then the mold after brushing is turned upside down on the conveying roller 100, and when it moves through the second spray pipe 303, the inside of the mold can be rinsed again through the spray head 302 on the second spray pipe 303, and due to the inverted state of the mold, the spray liquid that rinses the inside of the mold can be drained during the transportation process.

[0034] Reference Figure 3 and attached Figure 4, a mold side wall brushing unit 4, a mold turning mechanism 5 and a mold bottom wall brushing unit 6 are sequentially arranged in the inner cavity of the chassis 1 from left to right. Among them, the mold side wall brushing unit 4 includes a rotary switching motor 401 fixed to the top of the chassis 1, a longitudinal beam 402 is connected to the lower end of the rotary switching motor 401, a one-way screw 403 is rotatably connected in the longitudinal beam 402, and a first screw motor 404 is connected to one end of the one-way screw 403. A connecting block 405 threadedly connected to the one-way screw 403 is arranged in the longitudinal beam 402, and a transverse beam 406 is connected to the lower end of the connecting block 405, a first bidirectional screw 407 is rotatably connected in the transverse beam 406, and a second screw motor 408 is connected to one end of the first bidirectional screw 407. Moving seat blocks 409 are arranged at both ends of the transverse beam 406, and the two moving seat blocks 409 are adapted to the corresponding threads at both ends of the first bidirectional screw 407. A first roller brush motor 410 is installed at the upper end of each movable seat block 409, and a vertical roller brush 411 is connected to the lower end of each first roller brush motor 410. A large number of brush filaments (not shown in the figure) are arranged on the outer surface of the vertical roller brush 411, and a brush wheel 412 is also connected to the bottom end of the vertical roller brush 411.

[0035] In addition, a telescopic driving member 413 is provided just below the mold side wall brushing unit 4, and the upper end of the telescopic driving member 413 is connected to a push frame 414 that can extend from the roller gap of the conveying roller 100 and push the mold upward, and then two front-to-back symmetrical clamping plates 415 are provided inside the chassis 1 just above the push frame 414, and a pushing cylinder 416 connected to the clamping plates 415 is provided on the chassis 1. During operation, the mold side wall brushing unit 4 pushes the mold upward through the telescopic driving member 413 and the push frame 414 until the bottom wall of the mold contacts the brush wheel 412, and the mold is clamped by the two clamping plates 415. Then, the second screw motor 408 is controlled to rotate the first bidirectional screw 407. Under the transmission of the first bidirectional screw 407 and the movable seat block 409, the two vertical roller brushes 411 move in opposite directions until they contact the side wall of the mold. Then, the first roller brush motor 410 and the first screw motor 404 are synchronously started, so that the two high-speed rotating vertical roller brushes 411 brush the left and right side walls of the mold from left to right in turn. After the left and right side walls of the mold are brushed, the rotation switching motor 401 is started to control it to rotate 90°, and the above steps are repeated to brush the front and back side walls of the mold. When all the inner walls around the mold are brushed, the clamping force is withdrawn, and then it is lowered to the conveying roller 100 for conveying.

[0036] Reference Figure 1 , Attachment Figure 3 and attached Figure 5The mold flipping mechanism 5 includes a rotating support plate 501 that is rotatably arranged inside the chassis 1. The lower right end of the rotating support plate 501 is connected to the chassis 1 through a pin rod. At the same time, a rotating driving device 502 that acts on the pin rod is also arranged on the side of the chassis 1. The rotating driving device 502 can specifically use a cylinder to drive the gear to move, and then realize the switching between the horizontal and vertical states of the rotating support plate 501 through the meshing action between the rack and the gear on the pin rod. The rotating support plate 501 is at the same level as the conveying roller 100 in the horizontal state, so that the mold can be smoothly sent into it. In addition, in order to ensure the stability of the mold during the flipping process, two front-to-back symmetrical extrusion clamps 504 are connected to the rotating support plate 501 through an elastic member 503, and the ends of the two extrusion clamps 504 close to the mold side wall brushing unit 4 are designed to be open in an eight-shaped shape, so that the mold can enter between the two conveniently, and the mold is clamped and fixed under the action of the elastic member 503.

[0037] Reference Figure 3 , Attachment Figure 6 and attached Figure 8 The mold bottom wall brushing unit 6 includes a rotating beam frame 601 rotatably connected to the upper end of the inner cavity of the chassis 1, and a hydraulic telescopic rod 602 connected to the rotating beam frame 601 is arranged on the chassis 1, and the switching of the rotating beam frame 601 between the horizontal and vertical states is achieved by controlling the extension or shortening of the hydraulic telescopic rod 602. A lifting beam frame 603 that can move up and down is arranged inside the rotating beam frame 601, and the lifting beam frame 603 is arranged perpendicular to the rotating beam frame 601, and then the lifting beam frame 603 is arranged at the front and rear ends of the lifting beam frame 603 along the arms 604, and a horizontal roller brush 605 is arranged between the two along the arms 604. The outer surface of the horizontal roller brush 605 is also provided with a large number of brush wires (not shown in the figure), and a second roller brush motor 606 is connected to one end of the horizontal roller brush 605. In addition, a lifting drive device 607 for driving the lifting beam 603 to move up and down is provided on the lifting beam 603. The specific lifting drive device 607 is a multi-stage telescopic rod arranged at the upper end of the lifting beam 603, and the lower end of the multi-stage telescopic rod is connected to the lifting beam 603.

[0038] The mold bottom wall brushing unit 6 is used in conjunction with the mold turning mechanism 5. The mold turning mechanism 5 first turns the clamped mold to a vertical state, and then the rotating beam 601 is turned to a vertical state under the action of the hydraulic telescopic rod 602. At this time, the horizontal roller brush 605 on the lifting beam 603 extends into the mold and contacts its bottom wall, and then the second roller brush motor 606 and the lifting drive device 607 are started, so that the high-speed rotating horizontal roller brush 605 brushes the bottom wall of the mold from bottom to top or from top to bottom. After the brushing is completed, the mold bottom wall brushing unit 6 is reset to a horizontal state and stored at the upper end of the inner cavity of the chassis 1, and then the mold turning mechanism 5 continues to rotate a certain angle, so that the mold slips from the rotating support plate 501 under its own gravity and is inverted on the conveying roller 100, and then the mold passes through the second spray pipe 303 under the action of the conveying roller 100, and the cleaning liquid sprayed from the spray head 302 on the second spray pipe 303 is used to rinse its interior. Example 2

[0039] Example 2 discloses a small prefabricated component mold cleaning device that is improved and designed based on Example 1. The similarities between it and Example 1 are not described again. The differences between them are shown in the attached figure. Figure 1 and attached Figure 7 .

[0040] In this embodiment 2, an industrial camera 7 is also provided at the left end of the chassis 1, and an image processing module and a central control module electrically connected to the industrial camera 7 are provided inside the control cabinet 2. When the small prefabricated component mold to be cleaned enters the interior of the chassis 1, it is photographed by the industrial camera 7, and the photo is transmitted to the image processing module and the central control module for analysis and processing, so as to obtain the length and width dimensions inside the mold, and the number of rotations of the second screw motor 408 in the mold side wall brushing unit 4 can be directly controlled according to the obtained length and width dimensions, so as to adjust the distance between the two vertical roller brushes 411 to a distance dimension suitable for the mold, and then the side wall of the mold can be directly brushed after the mold is lifted up and clamped.

[0041] At the same time, in order to ensure that the mold bottom wall brushing unit 6 can effectively brush the mold bottom wall of different widths, the horizontal roller brush 605 is also designed as a telescopic structure. In the specific setting, a second bidirectional screw 608 is arranged in the lifting beam frame 603, and a third screw motor 609 is connected to one end of the second bidirectional screw 608. At the same time, an end block 610 threadedly connected to the two ends of the second bidirectional screw 608 is arranged at the end of each side arm 604, and then the two side arms 604 can move closer to or away from each other under the action between the second bidirectional screw 608 and the end block 610.

[0042] In addition, the horizontal roller brush 605 in the second embodiment includes a left socket section 6051 and a right plug section 6052, and the outer ends of the left socket section 6051 and the right plug section 6052 are both rotatably connected to the corresponding along arm 604. A plurality of axial strip grooves 6053 are evenly arranged on the outer circumferential surface of the left socket section 6051, and an axial insert strip 6054 matching each axial slide groove 6053 is connected to the right plug section 6052, so that in the process of the along arm 604 approaching or moving away from each other, the axial insert strip 6054 can move along the axial slide groove 6053, but the two will still rotate synchronously due to the existence of the above structure. Finally, corresponding brush wires are arranged on the outer circumferential surfaces of the left socket section 6051, the right plug section 6052 and the axial insert strip 6054, so that in the process of the horizontal roller brush 605 rotating, the dislocated brush wires on the left socket section 6051 and the right plug section 6052 can still effectively scrub the bottom wall of the mold in an all-round manner.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
