Description

Technical Field

[0001] The utility model relates to the technical field of concrete prefabricated component production equipment, in particular to a mold platform cleaning machine and a concrete prefabricated component production line. Background Art

[0002] After the formwork for concrete precast parts is used once, concrete residues remain on the surface of the formwork, which needs to be cleaned before it can be used again. At present, there are two main ways to clean the formwork: manual cleaning and cleaning machine cleaning. When cleaning manually, the cleaning quality of the formwork is easily affected by the operator's subjective influence, the cleaning quality is unstable and the efficiency is low, which is not suitable for the current assembly line operation mode.

[0003] In order to improve the cleaning efficiency and realize the assembly line operation of precast concrete parts, a cleaning machine is usually used to clean the formwork table. The existing cleaning machine has a relatively simple structure, and generally uses structures such as a scraper and a roller brush to clean the table top of the formwork table, and the edge of the formwork table is usually welded with a longitudinal or transverse side mold. In actual application scenarios, after the scraper and other processes loosen the residue on the table top, the roller brush cleans the residue on the table top. At this time, there is a cleaning dead corner near the bottom of the side mold or at the corner where the transverse and longitudinal side molds are connected, and the roller brush cannot clean the residue in the cleaning dead corner.

[0004] Therefore, the existing cleaning machines have problems such as dead corners at the side molds of the mold table, incomplete cleaning, and poor cleaning quality, which often require manual rework, is time-consuming and labor-intensive, and reduces production efficiency. Utility Model Content

[0020] In an optional embodiment, the scraper, the first air blowing device, and the dust collector are all installed on the outer shell and located inside the cover.

[0042] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0043] In the related art precast concrete component production line, a circulating formwork platform 5 is usually used for assembly line production. After one production is completed, the empty formwork platform 5 is transferred to a cleaning station, and the cleaning machine cleans the formwork platform 5 before the formwork platform 5 can enter the secondary production process.

[0044] like Figure 1 As shown, the edge of the mold platform 5 used in the related art is usually welded with a side mold, which includes a longitudinal side mold 51 arranged along the length direction of the mold platform 5 and a transverse side mold 52 arranged along the width direction of the mold platform 5. When the cleaning machine cleans the mold platform 5, the bottom of the longitudinal side mold 51 and the transverse side mold 52 close to the surface of the mold platform 5, and the corner where the longitudinal side mold 51 and the transverse side mold 52 are connected have cleaning dead corners and cannot be cleaned, resulting in the problem that the mold platform 5 is not cleaned thoroughly and the cleaning quality is poor.

[0045] Based on this, the utility model provides a formwork cleaning machine and a concrete precast component production line to solve the problem that the existing formwork cleaning machine has a cleaning dead angle at the side form of the formwork 5, resulting in incomplete cleaning and poor cleaning quality.

[0046] Combine the following Figures 1 to 11 , describing an embodiment of the utility model.

[0047] On the one hand, the utility model provides a formwork cleaning machine, including a frame 1 and a cleaning mechanism 3 which is liftable and arranged on the frame 1 , wherein the cleaning mechanism 3 includes a scraper 31 for loosening concrete impurities on the formwork 5 and a first air blowing device 32 for blowing the formwork 5 .

[0048] Specifically, the first air blowing device 32 has an air jet 320, and the first air blowing device 32 is suitable for blowing the mold platform 5 through the air jet 320, and the blowing range of the air jet 320 covers the width direction of the mold platform 5. In the flow direction along the mold platform 5, the air jet 320 is located downstream of the scraper 31.

[0049] In this embodiment, the scraper 31 of the cleaning mechanism 3 and the first air blowing device 32 work together, and the air jet 320 is located downstream of the scraper 31 along the flow direction of the mold platform 5. In addition, the blowing range of the air jet 320 of the first air blowing device 32 covers the width direction of the mold platform 5, that is, the blowing range of the air jet 320 can cover the positions of the longitudinal side mold 51 and the transverse side mold 52.

[0050] First, in actual application scenarios, a pre-cleaning process is usually provided upstream of the flow direction of the mold platform 5, and the pre-cleaning process loosens the concrete at the transverse side mold 52, and the scraper 31 of this embodiment can loosen the concrete on the mold platform 5 during the flow of the mold platform 5. After the pre-cleaning process and the upstream scraper 31 loosening process, concrete impurities remain at the bottom of the transverse side mold 52 near the mold platform 5. When the transverse side mold 52 of the mold platform 5 flows to the bottom of the first air blowing device 32, the blowing range of the air jet 320 can cover the transverse side mold 52. Therefore, the first air blowing device 32 can blow concrete impurities away from the bottom of the transverse side mold 52, thereby cleaning the bottom of the transverse side mold 52.

[0051] Secondly, after the scraping process of the upstream scraper 31, concrete impurities remain at the bottom of the longitudinal side mold 51 close to the mold platform 5. During the circulation of the mold platform 5, the blowing range of the air jet 320 can cover the longitudinal side mold 51. Therefore, the first air blowing device 32 can blow the concrete impurities away from the bottom of the longitudinal side mold 51, thereby cleaning the bottom of the longitudinal side mold 51.

[0052] Therefore, when cleaning the side mold parts of the mold platform 5 (the above-mentioned longitudinal side mold 51 and transverse side mold 52), the air jet 320 blows out the impurities in the cleaning dead corners of the side molds of the mold platform 5, so as to clean the cleaning dead corners of the side molds of the mold platform, thereby making the mold platform 5 thoroughly cleaned, thereby improving the cleaning effect.

[0053] It should be noted that the die table 5 is usually circulated along the length direction. Fig. 9 The direction A shown is the flow direction of the mold platform 5 , that is, the width direction of the mold platform 5 is perpendicular to the flow direction A of the mold platform 5 . The upstream and downstream in this article refer to the upstream and downstream along the flow direction of the mold platform 5 .

[0054] Furthermore, in some embodiments, the cleaning mechanism 3 further includes a dust suction device 33 and a cleaning device 34. The dust suction device 33 has a dust suction port 330. The dust suction device 33 is suitable for sucking impurities from the mold platform 5 through the dust suction port 330. The cleaning device 34 is used to clean impurities from the surface of the mold platform 5. In the flow direction along the mold platform 5, the dust suction device 33 and the cleaning device 34 are both located downstream of the scraper 31.

[0055] In this embodiment, the first air blowing device 32 can blow out impurities at the bottom of the longitudinal side mold 51 and the transverse side mold 52. The dust suction device 33 and the cleaning device 34 are used to clean the impurities blown onto the surface of the mold platform by the first air blowing device 32, as well as the concrete impurities loosened by the scraper 31, thereby realizing a combined cleaning of the mold platform by first loosening, then blowing, sucking and sweeping, further improving the cleaning effect.

[0056] For example, see Figure 2 and Fig. 9 The die table cleaning machine further includes a lifting mechanism 2, through which the cleaning mechanism 3 is escalably mounted on the frame 1, so that the cleaning mechanism 3 can be escalably arranged above the die table 5 to avoid interference between the cleaning mechanism 3 and the side die. The lifting mechanism 2 is a common device in the prior art, such as a linear motor, a drive cylinder, a screw nut mechanism, etc., which will not be described in detail here.

[0057] In some embodiments, the cleaning mechanism 3 further includes a housing 35; the first air blowing device 32 includes a purge assembly 322, which is extended along the width direction of the mold platform 5 (the width direction is perpendicular to the A direction), and is swingably arranged on the housing 35 along the flow direction of the mold platform 5 to adjust the purge direction of the purge assembly 322. The purge assembly 322 arranged in this way facilitates adaptive adjustment of the purge direction according to actual conditions to ensure the purge effect and improve the cleaning quality.

[0058] like Fig.10 and Fig.11 As shown, Fig.10 and Fig.11 The schematic diagrams of the structure of the purge assembly in two purge directions are shown respectively.

[0059] For example, the purge assembly 322 can adjust the swing angle by adjusting the installation position or the external driving structure to achieve the adjustment of the purge direction.

[0060] In some embodiments, Figure 6 As shown, the purge assembly 322 includes a vent pipe 3221 and a nozzle 3222. The vent pipe 3221 is rotatably arranged on the housing 35; the nozzle 3222 is arranged on the vent pipe 3221 and communicated with the vent pipe 3221, and the jet port 320 is arranged on the nozzle 3222. During purging, the vent pipe 3221 can enable the nozzle 3222 to have sufficient instantaneous air blowing pressure, thereby ensuring the purging effect. In addition, when the vent pipe 3221 rotates relative to the housing 35, it can drive the nozzle 3222 to rotate synchronously, thereby realizing the adjustment of the purging direction.

[0061] In some embodiments not shown, along the width direction of the mold platform 5, the two ends of the purge assembly 322 are extended with a rotating shaft portion, and the rotating shaft portion is connected to the driving end of an electric drive structure (such as a motor). The electric drive structure is suitable for driving the purge assembly 322 to rotate through the rotating shaft portion to adjust the purge direction of the jet port 320.

[0062] Exemplarily, the nozzle 3222 can be configured as a nozzle-shaped structure, or the nozzle 3222 can be configured as a flat structure. Preferably, the nozzle 3222 is configured as a flat structure, and the cross-sectional size of the nozzle 3222 gradually decreases in the direction away from the vent pipe 3221, so as to form a slit-shaped air jet 320 at the bottom of the nozzle 3222 away from the vent pipe 3221, and the instantaneous air blowing pressure of the slit-shaped air jet 320 is higher, and the blowing effect is better.

[0063] In some embodiments not shown, the nozzle 3222 is configured as an integral structure and spans the width direction of the mold stage 5 , so that the blowing direction of the air jet 320 covers the width direction of the mold stage 5 .

[0064] In some embodiments, a plurality of nozzles 3222 are provided, and the plurality of nozzles 3222 are arranged on the vent pipe 3221 at intervals along the axial direction of the vent pipe 3221. In this arrangement, the size of the nozzle 3222 is small, which can further increase the instantaneous air blowing pressure of the nozzle 3222 and ensure the blowing effect.

[0065] It should be noted that the vent pipe 3221 extends along the width direction of the mold platform 5, that is, the axial direction of the vent pipe 3221 is the width direction of the mold platform 5. Further, the multiple nozzles 3222 are arranged on the same straight line along the axial direction of the vent pipe 3221, so that the jet ports 320 of each nozzle 3222 can be located on the same straight line, ensuring the purging effect in the entire width direction of the mold platform 5. In addition, when the vent pipe 3221 rotates relative to the housing 35, the multiple nozzles 3222 can be driven to rotate synchronously.

[0066] Exemplarily, each nozzle 3222 is configured as a flat trumpet-shaped structure, and the bottom of each nozzle 3222 is formed as a slit-shaped air jet outlet 320 .

[0067] Exemplarily, the ventilation pipe 3221 has a plurality of gas distribution joints extending outward in the axial direction, and the plurality of nozzles 3222 are connected to the plurality of gas distribution joints in a one-to-one correspondence, and the ventilation pipe 3221 supplies air to the nozzles 3222 through the gas distribution joints.

[0068] In some embodiments, the first air blowing device 32 further includes a connecting assembly 321, the connecting assembly 321 includes a support 3211 and a pipe clamp 3212 connected to each other, the support 3211 is fixedly connected to the housing 35, and the pipe clamp 3212 is rotatably connected to the ventilation pipe 3221. Through the rotatable connection between the pipe clamp 3212 and the ventilation pipe 3221, the purge assembly 322 is swingably arranged on the housing 35, which has a simple structure and low production cost.

[0069] Exemplarily, the support 3211 is provided with two arms with an "L"-shaped cross section, and one of the arms is connected to the housing 35 (e.g., bolted), and the other arm is connected to the pipe clamp 3212 (e.g., bolted). Exemplarily, the pipe clamp 3212 includes a first half 3212a and a second half 3212b that are detachably connected, and the vent 3221 is clamped between the first half 3212a and the second half 3212b. One end of the support 3211 is connected to the housing 35, and the other end is connected to one of the first half 3212a or the second half 3212b.

[0070] The first half 3212a and the second half 3212b can be used to clamp the vent pipe 3221 by bolts. When the blowing direction of the blowing assembly 322 needs to be adjusted, the bolts of the first half 3212a and the second half 3212b are loosened to make the vent pipe 3221 in a loose state. At this time, the vent pipe 3221 can be rotated to a desired angle, and then the bolts are tightened. In this way, the vent pipe 3221 drives the nozzle 3222 to rotate synchronously, thereby adjusting the blowing direction.

[0071] It is understandable that the pipe clamp 3212 of the present application is not limited to the above structure, as long as it can achieve the function of clamping and loosening the ventilation pipe 3221.

[0072] Exemplarily, the connection assembly 321 may be provided in multiple groups, and the multiple groups of connection assemblies 321 are arranged at intervals along the axial direction of the ventilation pipe 3221, and are staggered with the above-mentioned gas distribution joints along the circumferential direction of the ventilation pipe 3221.

[0073] Furthermore, the cleaning mechanism 3 further includes an air supply device 323, such as Figure 6As shown, the gas supply device 323 includes a gas tank 3231 and an air path structure 3232 . The gas tank 3231 supplies high-pressure gas to the ventilation pipe 3221 through the air path structure 3232 , and the gas tank 3231 can store gas to further ensure the instantaneous air blowing pressure of the air jet 320 .

[0074] Exemplarily, the air path structure 3232 may be provided with one group and connected to the end or the middle of the ventilation pipe 3221; or, the air path structure 3232 may be provided with two groups, and the two groups of air path structures 3232 are respectively connected to the two ends of the ventilation pipe 3221 to supply air to the ventilation pipe 3221 at both ends of the ventilation pipe 3221 at the same time.

[0075] In some embodiments, the cleaning mechanism 3 further includes a shell 35, which is a cover body with openings at both ends and the bottom, and is used to prevent dust from splashing; the dust suction device 33 includes a dust suction head 331, and the dust suction head 331 includes a joint part 3311 and a suction head part 3312 that are connected to each other, and the joint part 3311 is connected and extends out of the top of the shell 35, and the dust suction port 330 is arranged at the bottom of the dust suction head 331, and the dust suction range of the dust suction port 330 covers the width direction of the mold platform 5. In this way, when the mold platform 5 flows along the flow direction, the dust suction port 330 can clean the small particles of impurities or floating dust blown out by the air jet 320 in the width direction of the mold platform 5, and the dust suction range can cover the entire surface of the mold platform 5, especially near the side mold, and the dust suction effect is better.

[0076] For example, Figure 7 and Figure 8 As shown, the suction head portion 3312 is constructed as a flat structure, and the cross-sectional size of the suction head portion 3312 gradually decreases in the direction away from the joint portion 3311. Preferably, the suction head 331 is constructed as a duckbill structure.

[0077] It is understandable that the dust suction head 331 extends along the width direction of the mold platform 5 so that the dust suction range of the dust suction port 330 can cover the width direction of the mold platform 5 .

[0078] Exemplarily, a connecting flange is provided on the joint part 3311, and a connecting hole is correspondingly provided on the top of the shell 35. The joint part 3311 extends out of the top of the shell 35 through the connecting hole and is fixed to the shell 35 through the connecting flange. Exemplarily, a connecting piece may also be provided on the suction head 3312, and connected to the shell 35 through the connecting piece to ensure the stability of the suction head 331 during vacuuming.

[0079] In some embodiments, the vacuum head 331 also includes two baffle portions 3313, which are adjustably connected to the bottom of the vacuum head portion 3312 in the upper and lower positions and respectively cover the front and rear sides of the vacuum port 330. At least part of the structure of the baffle portion 3313 can extend downward from the vacuum head portion 3312.

[0080] It is understandable that the smaller the gap between the dust suction port 330 and the surface of the mold platform 5, the better the dust suction effect. The baffle portion 3313 can adjust the gap size between the dust suction port 330 and the mold platform 5 by adjusting the upper and lower positions, further ensuring the dust suction effect.

[0081] For example, the baffle portion 3313 may be provided with a U-shaped groove extending in the up-down direction, and may be fixed to the suction head portion 3312 by bolts, so as to achieve an adjustable setting of the up-down position. For example, the baffle portion 3313 may also achieve an adjustable setting of the up-down position by a driving structure such as a cylinder.

[0082] Furthermore, the cleaning mechanism 3 also includes a negative pressure device, which is connected to the joint portion 3311 at the top of the shell 35 to provide negative pressure for the dust collector 331 .

[0083] In some application scenarios, the mold table 5 has two workstations along the width direction. In some embodiments, two vacuum heads 331 may be arranged side by side along the width direction of the mold table 5 , and the two vacuum heads 331 vacuum one of the workstations of the mold table 5 respectively.

[0084] Exemplarily, the joints 3311 of the two suction heads 331 are connected and extend from the top of the housing 35 to be connected to the negative pressure device. Exemplarily, another interface can be provided in the middle of the two joints 3311, and the negative pressure device is connected to the interface to absorb the floating dust between the two suction heads 331.

[0085] In some embodiments, the scraper 31, the first air blowing device 32, the dust collecting head 331 and the cleaning device 34 are all installed on the housing 35 and are located inside the cover. In this way, the scraper 31, the first air blowing device 32, the dust collecting head 331 and the cleaning device 34 are all integrated on the housing 35, with better linkage and high cleaning reliability.

[0086] Exemplarily, the lifting mechanism 2 is connected to the top of the shell 35, and the lifting and lowering of the cleaning mechanism 3 can be achieved by driving the shell 35 to move up and down.

[0087] Furthermore, Figure 4 and Figure 5 Two embodiments of the die table cleaning machine are shown.

[0088] Specifically, Figure 4As shown, in some embodiments, the cleaning device 34 includes a roller brush 341 and a scraper 342, the roller brush 341 is rotatably connected to the housing 35, the blade 31 and the scraper 342 are respectively connected to the front and rear sides of the housing 35, and the blade 31, the first air blowing device 32, the roller brush 341, the dust suction head 331 and the scraper 342 are sequentially arranged along the flow direction of the mold platform. In this way, along the flow direction of the mold platform 5, the first air blowing device 32 blows downstream of the blade 31, and impurities such as concrete blocks or particles can be cleaned through the three cleaning processes of the roller brush 341, the dust suction head and the scraper 342, further ensuring the cleaning effect.

[0089] Among them, the scraper blade 31 and the scraper plate 342 can be fixed to the shell 35 by bolts, and the roller brush 341 device can be rotatably connected to the shell 35 by an electric drive structure, etc., which will not be repeated here.

[0090] Specifically, Figure 5 As shown, in some embodiments, the cleaning mechanism 3 further includes a second air blowing device 36, and in the flow direction along the mold platform 5, the second air blowing device 36 is arranged upstream of the dust suction head 331 and / or the second air blowing device 36 is arranged upstream of the scraper 342. Arranging the second air blowing device 36 upstream of the dust suction head 331 and / or the scraper 342 can further ensure the blowing effect, thereby improving the cleaning quality.

[0091] Exemplarily, one second air blowing device 36 may be provided, and along the flow direction of the mold table 5 , the second air blowing device 36 may be provided upstream of the dust collecting head 331 and close to the dust collecting head 331 .

[0092] Exemplarily, one second air blowing device 36 may be provided, and along the flow direction of the mold table 5 , the second air blowing device 36 may be provided upstream of the scraper 342 and close to the scraper 342 .

[0093] For example, Figure 5 As shown, two second air blowing devices 36 may be provided. Along the flow direction of the mold table 5 , the two second air blowing devices 36 are respectively provided upstream of the dust collecting head 331 and the scraper 342 .

[0094] Exemplarily, the second air blowing device 36 may have the same structure as the first air blowing device 32 , and the air supply to the second air blowing device 36 is realized by the air supply device 323 , which will not be described in detail herein.

[0095] Further, such as Figures 9 to 11 As shown, the die table cleaning machine further includes a material receiving box 4, which is used to receive impurities cleaned by the cleaning mechanism 3 below the die table 5. Exemplarily, two material receiving boxes 4 are provided, and are respectively arranged at the positions where the roller brush 341 and the scraper 342 are located.

[0096] by Fig.11 Taking the example shown above, the specific method of using the mold cleaning machine of the utility model is as follows:

[0097] When the mold platform 5 rotates and its lateral side mold 52 rotates to below the first air blowing device 32, the cleaning mechanism 3 descends to a position about 25 mm above the lateral side mold 52;

[0098] The first air blowing device 32 starts to work, and blows the transverse side mold 52. The small impurities of the concrete are blown out of the transverse side mold 52 by the instantaneous air blowing force, and fall into the receiving box 4. Some of the impurities are blown to the back of the transverse side mold 52.

[0099] The die table 5 moves forward again, and is cleaned by the roller brush 341 and the scraper 342 in turn, so that the remaining impurities are swept out of the die table 5 and fall into another receiving box 4, while the dust blown up by the air and the small particles that cannot be cleaned by the roller brush 341 are sucked away by the dust collector.

[0100] On the other hand, the utility model also provides a precast concrete component production line, comprising a formwork cleaning machine, a formwork 5, and a circulation system as described in any of the above embodiments. Specifically, the precast concrete component production line is provided with a cleaning station, the formwork cleaning machine is arranged at the cleaning station, and the circulation system is suitable for driving the formwork 5 to circulate and flow through the cleaning station to realize the cleaning work of the formwork cleaning machine on the formwork 5.

[0101] Since the concrete prefabricated component production line of the present invention includes the above-mentioned formwork cleaning machine, it has the same effect as the formwork cleaning machine of the present invention, and will not be described in detail here.

[0102] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
