Description

Technical Field

[0001] This application relates to the field of aluminum formwork use and maintenance equipment technology, and in particular to a release agent spraying device. Background Technology

[0002] When concrete is poured, multiple aluminum formworks are usually used. The connection area of ​​two adjacent aluminum formworks is fixed with pins and clips to form a pouring cavity. The aluminum formworks are removed after the concrete has hardened. To facilitate the removal of the aluminum formworks later, a release agent is sprayed on the working surface of the aluminum formwork as an interface coating to make the contact surface between the concrete and the aluminum formwork easy to separate and to keep the concrete facade smooth and clean.

[0003] To facilitate the application of release agent to the working surface of aluminum formwork, a release agent spraying device for aluminum formwork construction is disclosed in the prior art. The device includes a box, with a filter frame installed in the inner cavity of the box. A surrounding plate is connected to the top of the box, and a support plate is horizontally welded to the inner wall of the surrounding plate. Electric push rods are welded to the bottom of both sides of the box through support plates. A spraying mechanism is installed on the top of the electric push rods. A controller is bolted to the right side of the box, and a liquid outlet valve is connected to the bottom of the right side of the box.

[0004] Regarding the aforementioned technologies, the number of aluminum formworks to be sprayed at construction sites is generally large. Using the existing spraying equipment, it is necessary to wait for the current aluminum formwork to be sprayed before the next aluminum formwork can be installed, resulting in low overall spraying efficiency. Summary of the Invention

[0005] In order to improve the efficiency of mold release agent spraying for aluminum formwork, this application provides a mold release agent spraying device.

[0006] The mold release agent spraying device provided in this application adopts the following technical solution:

[0007] A mold release agent spraying device, comprising

[0008] A base, on which a mounting column is vertically connected;

[0009] Multiple trays are distributed around the mounting column in a circumferential manner. The trays are rotatably connected to the mounting column, and the rotation axis of the trays coincides with the axis of the mounting column. A limiting cylinder is coaxially rotatably connected to the tray, and the limiting cylinder is provided with a limiting groove for embedding the arc-shaped aluminum template connection area.

[0010] Mounting plate, through which the mounting column is installed;

[0011] A feeding rod is connected to the mounting plate, the axial direction of the feeding rod is consistent with the axial direction of the mounting column, and at least one nozzle is connected to the feeding rod;

[0012] A feeding unit is mounted on the mounting plate and connected to the feeding rod;

[0013] A lifting unit is mounted on the mounting column and connected to the mounting plate, which is used to allow the mounting plate to slide along the axial direction of the mounting column.

[0014] By adopting the above technical solution, when spraying release agent on the arc-shaped aluminum template of the molded column, multiple arc-shaped aluminum templates are first placed into the limiting cylinder, so that the multiple arc-shaped aluminum templates are spliced ​​together to form a molding cavity. At this time, the connecting area on the arc-shaped aluminum template is embedded in the limiting groove to prevent relative rotation between the arc-shaped aluminum template and the limiting cylinder. Then, the tray is rotated so that the tray containing the arc-shaped aluminum template is moved to be coaxial with the conveying rod. The lifting unit applies force to the mounting plate, and the mounting plate drives the feeding unit and the conveying rod to move, so that the conveying rod extends into the molding cavity. Then, the feeding unit inputs the release agent into the conveying rod. The release agent is sprayed out through the nozzle, and at the same time, the limiting cylinder is driven to rotate, completing the release agent spraying of the arc-shaped aluminum template. While the spraying operation is underway, the worker is working on another tray. For the installation of other types of aluminum formwork, after the curved aluminum formwork in the spraying position is sprayed, rotate the tray again to put the installed curved aluminum formwork in the spraying position, and then spray it again. The designed release agent spraying device is easy to fix the installation column through the base. The installation column is easy to cooperate with the lifting unit to realize the directional movement of the installation plate and the conveying rod. The feeding unit is easy to input the release agent into the conveying rod. The conveying rod and the nozzle are easy to spray the release agent evenly onto the working surface of the curved aluminum formwork. Through the rotating connection of multiple trays and installation columns, one spraying station and at least one loading station can be provided, so as to avoid the curved aluminum formwork being sprayed affecting the loading of the next batch of curved aluminum formwork, thereby improving the release agent spraying efficiency of the curved aluminum formwork.

[0015] In one specific implementation, the feeding unit includes

[0016] A feeding pump is provided, wherein the base is hollow and the feeding pump is located in the inner cavity of the base;

[0017] The telescopic tube is hollow in the mounting column. One end of the telescopic tube is connected to the feeding pump, and the other end extends out of the inner cavity of the mounting column and into the inner cavity of the mounting plate to connect with the conveying rod.

[0018] By adopting the above technical solution, the designed feeding unit can easily pump the release agent from the inner cavity of the base into the telescopic tube through the feeding pump. The telescopic tube can also adapt to changes in the height of the feeding rod while sending the release agent into the feeding rod.

[0019] In one specific implementation, a fixed ring is coaxially connected to the mounting column, and a rotating ring is sleeved on the mounting column. The rotating ring rotates relative to the fixed ring, and a connecting handle connects the rotating ring and the tray.

[0020] By adopting the above technical solution, the designed fixed ring, rotating ring, and multiple connecting handles can be used to achieve a rotating connection between the tray and the mounting column.

[0021] In one specific implementation, the connecting handle is hollow and inclined downward from the side near the tray to the side near the rotating ring. The inner cavity of the tray and the inner cavity of the rotating ring are connected through the inner cavity of the connecting handle. The fixed ring has at least one feed hole and the rotating ring has at least one discharge hole. After the rotating ring rotates, the discharge hole can communicate with the inner cavity of the mounting column through the feed hole.

[0022] By adopting the above technical solution, the hollow tray, connecting handle, fixing ring, rotating ring and mounting column designed in sequence can recover the release agent dripping after spraying into the inner cavity of the mounting column, and finally enter the inner cavity of the base for reuse under its own gravity.

[0023] In one specific implementation scheme, a load-bearing ring is further included, which is sleeved on the mounting column and a rotation gap is left between the load-bearing ring and the mounting column. A diagonal tie rod is provided between the load-bearing ring and each of the trays.

[0024] By adopting the above technical solutions, the designed load-bearing ring and diagonal brace can improve the structural stability of the pallet.

[0025] In one specific implementation scheme, a limiting unit is also included, the limiting unit comprising:

[0026] A protruding strip, which is connected to the mounting column;

[0027] A T-shaped rod, wherein the vertical section of the T-shaped rod passes through the protruding strip and is slidably connected to the protruding strip;

[0028] A spring, one end of which is connected to the protruding strip and the other end of which is connected to the horizontal section of the T-shaped rod, is provided with multiple limiting holes on the bearing ring. The spring is used to drive the T-shaped rod to be inserted into the limiting holes, and when the T-shaped rod is inserted into the limiting holes, the conveying rod is coaxially arranged with one of the trays.

[0029] By adopting the above technical solution, the designed limiting unit, through the cooperation of protruding strips, T-shaped rods and springs, can fix the position of the arc-shaped aluminum template during the spraying of the release agent, thereby avoiding the filling action of the arc-shaped aluminum template at the feeding position from affecting the release agent spraying operation of the arc-shaped aluminum template at the spraying position.

[0030] In one specific implementation scheme, a slewing unit is also included, the slewing unit comprising:

[0031] A rotary motor, which is connected to the base;

[0032] A fixed shaft is coaxially connected to the output shaft of the rotary motor, and the axial direction of the fixed shaft is consistent with the axial direction of the mounting column.

[0033] The friction wheel is coaxially connected to the fixed shaft, and when the T-shaped rod is inserted into the limiting hole, the friction wheel abuts against the limiting cylinder.

[0034] By adopting the above technical solution, the designed rotary unit can easily drive the fixed shaft to rotate through the rotary motor. The fixed shaft can easily install the friction wheel and realize the rotation of the friction wheel at the same time. The friction wheel can easily cooperate with the limiting cylinder, thereby realizing the rotation of the arc-shaped aluminum template spliced ​​into a whole. It can also cooperate with the spray head to complete the release agent spraying operation on the working surface of the arc-shaped aluminum template.

[0035] In one specific implementation scheme, the lifting unit includes

[0036] A drive motor, which is connected to the mounting column;

[0037] A drive screw, one end of which is coaxially connected to the output shaft of the drive motor, and the other end of which is threadedly connected to the mounting strip.

[0038] By adopting the above technical solution, the designed lifting unit can easily drive the drive screw to rotate through the drive motor, and the drive screw can easily cooperate with the mounting column to realize the lifting action of the mounting plate.

[0039] In one specific implementation, the drive screw is located between the mounting column and the feed rod.

[0040] By adopting the above technical solution, the designed drive screw located between the mounting column and the conveying rod can change the lever arm length between the external force exerted on the mounting plate by the conveying rod and the mounting column and the driving force of the mounting plate, thereby realizing the lifting and lowering movement of the mounting plate while reducing the power of the drive motor.

[0041] In summary, this application includes at least one of the following beneficial technical effects:

[0042] 1. The designed release agent spraying device facilitates the fixing of the mounting column via the base, and the mounting column facilitates the directional movement of the mounting plate and the conveying rod in conjunction with the lifting unit. The feeding unit facilitates the input of release agent into the conveying rod, and the conveying rod and nozzle facilitate the uniform spraying of release agent onto the working surface of the curved aluminum template. Through the rotatable connection of multiple trays with the mounting column, it can provide one spraying station and at least one loading station, avoiding the impact of the ongoing spraying of curved aluminum templates on the loading of subsequent batches of curved aluminum templates, thereby improving the release agent spraying efficiency of the curved aluminum templates.

[0043] 2. The designed mold release agent spraying device, through a hollow tray, connecting handle, fixing ring, rotating ring and mounting column connected in sequence, can collect the mold release agent dripping after spraying into the inner cavity of the mounting column.

[0044] 3. The designed release agent spraying device uses a rotary motor to easily drive the fixed shaft to rotate. The fixed shaft facilitates the installation of friction wheels while simultaneously enabling the rotation of the friction wheels. The friction wheels can easily cooperate with the limiting cylinder, thereby realizing the rotation of the assembled arc-shaped aluminum template. In conjunction with the spray head, the release agent spraying operation is completed on the working surface of the arc-shaped aluminum template. Attached Figure Description

[0057] This application discloses a mold release agent spraying device.

[0058] Reference Figure 1 A mold release agent spraying device includes a base 1 and a mounting column 2. The base 1 is horizontally positioned. To facilitate movement, four self-locking casters are bolted to the bottom wall of the base 1. The four self-locking casters are respectively positioned near the four corners of the base 1. The mounting column 2 is vertically welded to the top wall of the base 1. To improve the stability of the connection between the mounting column 2 and the base 1, four reinforcing ribs are welded and fixed between the mounting column 2 and the base 1.

[0059] Reference Figure 2To facilitate the application of release agent to the arc-shaped aluminum template 01 of the molded column and improve the spraying efficiency, multiple trays 3 are also included. The multiple trays 3 are distributed around the circumference of the mounting column 2. In this application, the multiple trays 3 can be evenly distributed or unevenly distributed around the circumference of the mounting column 2. In this embodiment, they are preferably evenly distributed. The trays 3 are rotatably connected to the mounting column 2, and the rotation axis of the trays 3 coincides with the axis of the mounting column 2. In this embodiment, the number of trays 3 can be two, three, or four. In this embodiment, the number of trays 3 is four.

[0060] Reference Figure 3 To facilitate the bearing and positioning of the curved aluminum template 01, each tray 3 is rotatably connected to a limiting cylinder 31. The limiting cylinder 31 is coaxially arranged with the tray 3, and the top wall of the limiting cylinder 31 is open. The upper edge of the limiting cylinder 31 is provided with a limiting groove 311 for the connection area of ​​the curved aluminum template 01 to be embedded. The bottom wall of the limiting cylinder 31 is provided with multiple through holes. In use, multiple curved aluminum templates 01 are first inserted into the limiting cylinder 31, and the connection area of ​​the curved aluminum template 01 is embedded in the limiting groove 311. Then, the multiple curved aluminum templates 01 are connected into a structural whole by external components such as bolts, and a forming cavity is formed between the structural wholes.

[0061] Reference Figure 4 To facilitate the application of release agent spraying on the working surface of the arc-shaped aluminum template 01, an installation plate 4 and a conveying rod 41 are also included. The installation plate 4 is horizontally arranged, and the installation column 2 is arranged through one end of the installation plate 4. The installation plate 4 and the installation column 2 are slidably connected. The conveying rod 41 is hollow, and the axial direction of the conveying rod 41 is consistent with the axial direction of the installation column 2. One end of the conveying rod 41 is welded and fixed to the installation plate 4. At least one nozzle 42 is connected to the flange on the conveying rod 41. In this application, the number of nozzles 42 can be one, two, or three. The nozzles 42 can be located on the same side of the conveying rod 41 or distributed along the circumference of the conveying rod 41. In this embodiment, the number of nozzles 42 is four. The four nozzles 42 are distributed along the axial direction of the conveying rod 41 and located on the same side of the conveying rod 41.

[0062] Reference Figure 5 To facilitate the lifting and lowering of the mounting plate 4, a lifting unit 6 is also included. The lifting unit 6 can be configured as a cylinder or as a combination of a drive motor 61 and a drive screw 62. In this embodiment, the lifting unit 6 includes a drive motor 61 and a drive screw 62. The body of the drive motor 61 is bolted to the mounting column 2, and the drive screw 62 is coaxially keyed to the output shaft of the drive motor 61. The drive screw 62 is threaded to the mounting plate 4, and the drive screw 62 is perpendicular to the mounting plate 4.

[0063] Reference Figure 5 In order to reduce the output power of the drive motor 61 while driving the mounting plate 4 to rise and fall, the drive screw 62 is located between the mounting column 2 and the conveying rod 41. An external power supply provides power for the drive motor 61 to work. The output shaft of the drive motor 61 drives the drive screw 62 to rotate. The drive screw 62 and the mounting column 2 work together to drive the mounting plate 4 to rise along the axial direction of the mounting column 2, which in turn drives the conveying rod 41 to rise. When the conveying rod 41 is directly above the molding cavity, the drive motor 61 reverses, so that the conveying rod 41 drives the nozzle 42 into the molding cavity formed by multiple arc-shaped aluminum templates 01.

[0064] Reference Figure 6 To facilitate the supply of release agent to the conveying rod 41, a feeding unit 5 is also included. The feeding unit 5 includes a feeding pump 51 and a telescopic tube 52. The base 1 and the mounting column 2 are both hollow, and the base 1 is provided with a feeding port, which is sealed by a threaded sealing cap. The feeding pump 51 is located in the inner cavity of the base 1 and is bolted to the base 1. One end of the telescopic tube 52 is connected to the discharge flange of the feeding pump 51, and the other end extends into the inner cavity of the mounting column 2 and passes through the inner cavity of the mounting plate 4, and finally connects to the upper flange of the conveying rod 41. The mounting column 2 is provided with a strip groove for the telescopic tube 52 to pass through and move up and down. An external power supply provides power for the operation of the feeding pump 51. The feeding pump 51 draws the release agent in the inner cavity of the base 1 into the telescopic tube 52, and then sends it into the conveying rod 41 through the telescopic tube 52, and finally sprays it onto the working surface of the arc-shaped aluminum template 01 through the nozzle 42.

[0065] Reference Figure 7 To facilitate the rotation of the tray 3 around the mounting column 2, a fixing ring 21, a rotating ring 22, and multiple connecting handles 23 are also included. The fixing ring 21 is welded and fixed to the mounting column 2, and the fixing ring 21 and the mounting column 2 are coaxially arranged. The rotating ring 22 is sleeved on the mounting column 2, and a relative rotation gap is left between the rotating ring 22 and the mounting column 2. In this application, the number of connecting handles 23 is the same as the number of trays 3. One end of the connecting handle 23 is welded to the tray 3, and the other end is welded and fixed to the rotating ring 22. The connecting handle 23 is inclined downward from the side closer to the tray 3 to the side closer to the rotating ring 22.

[0066] Reference Figure 7To facilitate the recycling of the release agent dripping into the tray 3, the fixing ring 21 is hollow, and its inner cavity is connected to the inner cavity of the mounting column 2. At least one feed hole 211 is provided on the top wall of the fixing ring 21. In this application, the number of feed holes 211 can be one, two, or three; in this embodiment, the number of feed holes 211 is three. The rotating ring 22 is hollow, and at least one discharge hole 221 is provided on its bottom wall. The number of discharge holes 221... There can be one, two, or three; in this embodiment, there are three. The connecting handle 23 is hollow and connects the inner cavity of the tray 3 with the inner cavity of the rotating ring 22. The nozzle 42 sprays the release agent onto the arc-shaped aluminum template 01. Some of the release agent drips into the limiting cylinder 31 due to its own gravity, then enters the tray 3, and finally enters the rotating ring 22 through the connecting handle 23. Then, it enters the inner cavity of the mounting column 2 through the discharge hole 221 on the rotating ring 22 and the inlet hole 211.

[0067] Reference Figure 8 Since the arc-shaped aluminum template 01 has a certain weight, in order to ensure the structural stability of the pallet 3, it also includes a load-bearing ring 24 and multiple diagonal braces 25. The load-bearing ring 24 is sleeved on the mounting column 2, and there is a relative rotation gap between the load-bearing ring 24 and the mounting column 2. The number of diagonal braces 25 is the same as the number of pallets 3. One end of the diagonal brace 25 is welded and fixed to the bottom wall of the pallet 3, and the other end is welded and fixed to the outer periphery of the load-bearing ring 24. In this application, the load-bearing ring 24 can be located above or below the fixed ring 21. In this embodiment, the load-bearing ring 24 is preferably located below the fixed ring 21.

[0068] Reference Figure 9 To improve the release agent spraying efficiency of the curved aluminum template 01, when spraying the release agent on the curved aluminum template 01 located on the test tray 3, the next batch of curved aluminum templates 01 needs to be loaded onto the loading tray 3. To prevent the rotating ring 22 from rotating during loading, which would cause the nozzle 42 to collide with the curved aluminum template 01, a limiting unit 7 is also included. The limiting unit 7 includes a protruding strip 71, a T-shaped rod 72, and a spring 73. The protruding strip 71 is welded and fixed to the mounting column 2, and the T-shaped rod 73... The vertical section of the T-shaped rod 72 passes through the protruding strip 71, and the vertical section of the T-shaped rod 72 is slidably connected to the protruding strip 71. One end of the spring 73 is welded to the protruding strip 71, and the other end is welded to the horizontal section of the T-shaped rod 72. The bearing ring 24 is provided with multiple limiting holes 241. In this application, the number of limiting holes 241 on the bearing ring 24 is the same as the number of trays 3. The spring 73 applies force to the T-shaped rod 72, so that the vertical section of the T-shaped rod 72 is inserted into the limiting hole 241. At this time, the conveying rod 41 is coaxial with one of the trays 3.

[0069] Reference Figure 10To facilitate the overall rotation of the arc-shaped aluminum template 01 structure, a rotary unit 8 is also included. The rotary unit 8 includes a rotary motor 81, a fixed shaft 82, and a friction wheel 83. The rotary motor 81 is bolted to the base 1. The fixed shaft 82 is coaxially keyed to the output shaft of the rotary motor 81, and the axial direction of the fixed shaft 82 is consistent with the axial direction of the mounting column 2. The friction wheel 83 is coaxially engaged with the end of the fixed shaft 82 away from the rotary motor 81. When the T-shaped rod 72 is inserted into the limiting hole 241, the friction wheel 83 abuts against the outer periphery of the limiting cylinder 31 in the spraying position. An external power supply provides electrical energy for the rotary motor 81 to work. The rotary motor 81 drives the friction wheel 83 to rotate through the fixed shaft 82. The friction wheel 83 drives the limiting cylinder 31 to rotate through friction, thereby realizing the relative rotation of the arc-shaped aluminum template 01 and the spray head 42, and achieving uniform spraying of the release agent.

[0070] The implementation principle of the mold release agent spraying device in this application embodiment is as follows: multiple arc-shaped aluminum templates 01 are connected to form a structural whole, and then force is applied to the structural whole so that the connecting area of ​​the arc-shaped aluminum templates 01 is inserted into the limiting groove 311 opened on the upper edge of the limiting cylinder 31, so that the relative position of the arc-shaped aluminum templates 01 and the limiting cylinder 31 is fixed in the horizontal direction.

[0071] Then, force is applied to the tray 3. The tray 3 applies force to the rotating ring 22 through the connecting handle 23 and to the bearing ring 24 through the diagonal tie rod 25, so that the rotating ring 22 and the bearing ring 24 rotate relative to the mounting column 2 until the tray 3 rotates to the spraying position. At this time, the vertical section of the T-shaped rod 72 is inserted into the limiting hole 241 under the action of the spring 73. Then, the next batch of arc-shaped aluminum template 01 is loaded at the loading position.

[0072] An external power supply provides electrical energy for the drive motor 61 to work. The output shaft of the drive motor 61 drives the drive screw 62 to rotate. The drive screw 62 and the mounting column 2 cooperate to make the mounting plate 4 move towards the base 1. While the mounting plate 4 is moving, it drives the material conveying rod 41 and the nozzle 42 into the molding cavity formed by multiple arc-shaped aluminum templates 01.

[0073] At this time, the external power supply provides power to the rotary motor 81. The output shaft of the rotary motor 81 drives the friction wheel 83 to rotate through the fixed shaft 82. The friction wheel 83 drives the limiting cylinder 31 to rotate through friction. The limiting cylinder 31 drives the arc-shaped aluminum template 01 to rotate relative to the nozzle 42. The external power supply provides power to the feeding pump 51. The feeding pump 51 sends the release agent into the conveying rod 41 through the telescopic tube 52. Finally, it is sprayed out through the nozzle 42 onto the working surface of the arc-shaped aluminum template 01. The dripping release agent enters the inner cavity of the tray 3 through the through hole. Then, under its own gravity, it enters the inner cavity of the rotating ring 22 through the inner cavity of the connecting handle 23. When the discharge hole 221 and the feed hole 211 are aligned, the release agent enters the fixed ring 21. Finally, it enters the inner cavity of the base 1 through the inner cavity of the mounting column 2 for reuse.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
