Description

Technical Field

[0001] The invention relates to the technical field of prefabricated component production equipment, and particularly discloses a device for automatically applying a release agent to a prefabricated component mold. Background Art

[0002] During the production of precast concrete parts, a release agent must be applied or sprayed onto the inner wall of the mold before pouring the concrete slurry. This prevents the concrete component from sticking to the mold during demolding, ensuring easy demolding and maintaining surface quality. Currently, most precast component mold release agents are applied manually by spraying them onto the mold's inner wall using a handheld spray can. This process is labor-intensive and inefficient, and manual spraying cannot guarantee uniform application, which can easily result in a high number of defective parts during demolding.

[0003] The utility model patent application number 2020203459759 discloses a release agent spraying mechanism for precast concrete parts, including a crossbeam and a column supporting the crossbeam. The crossbeam is provided with a height-adjustable vertical pole, and a bracket is installed at the lower end of the vertical pole. The bracket is provided with a number of nozzles corresponding to the mold cavity; the bracket includes an upper mounting plate and a lower mounting plate, which are supported by a vertical plate. The middle part of the upper end surface of the upper mounting plate is connected to the lower end of the vertical pole. The bracket is also provided with a steering mechanism corresponding to the nozzle for changing the spraying direction of the nozzle. The release agent spraying mechanism disclosed in this utility model patent is generally used in conjunction with a precast mold conveyor. The mold is conveyed at a uniform speed by the precast mold conveyor, and then the release agent spraying mechanism is used to spray the inner wall of the mold during the conveying process, thereby greatly improving the efficiency of spraying the release agent on the precast component mold before pouring. However, during the conveyance of the precast mold, the release agent spraying mechanism can only evenly spray the mold bottom wall. The mold inner sidewalls and the four corners of the bottom edge cannot be evenly coated with release agent. As a result, when the precast mold is subsequently shaped, burrs appear on the four sidewalls and four lower edges of the precast product during demolding, seriously affecting the surface quality of the entire precast component. In view of the above-mentioned shortcomings of the existing release agent spraying mechanism for concrete precast parts, the present application proposes an automatic release agent application device for precast component molds that can effectively ensure uniform spraying of the interior of the precast component mold. Summary of the Invention

[0004] The present invention aims to provide a device for automatically applying a release agent to a prefabricated component mold, so as to realize the assembly line spraying of the release agent on the prefabricated component mold, effectively ensuring that a uniform layer of release agent can be applied to the interior of the prefabricated component mold, so as to ensure the product quality of the prefabricated component after demolding.

[0005] The present invention is achieved through the following technical solutions:

[0006] A device for automatically applying a mold release agent to a prefabricated component mold comprises a mold conveying unit, a mold release agent supply unit, and a spraying unit, wherein the spraying unit is arranged above the mold conveying unit, the mold release agent supply unit is connected to the spraying unit, and a mold clamping and rotating mechanism is provided in the mold conveying unit directly below the spraying unit, wherein the mold clamping and rotating mechanism comprises a semi-cylindrical support rotatably arranged in the mold conveying unit and a driving device for realizing directional rotation of the semi-cylindrical support, a row of rollers being rotatably connected to an opening in the upper end surface of the semi-cylindrical support, and clamping plates for clamping and fixing the mold are provided at both the front and rear ends of the semi-cylindrical support located above the rollers;

The front and rear ends of the nozzle mounting plate are both provided with a first nozzle arranged obliquely outward and downward. A plurality of second nozzles arranged vertically downward are arranged at intervals on the nozzle mounting plate located between the two first nozzles. The first nozzle and the second nozzle are both connected to the release agent supply unit.

[0008] As a first design scheme of the above-mentioned semi-cylindrical support, an arc-shaped rack is provided on the outer circular surface of the lower end of the semi-cylindrical support, and a group of arc-shaped rollers are connected to the front and rear side surfaces of the semi-cylindrical support. The mold conveying unit is provided with an arc-shaped track that cooperates with the rollers, and the driving device includes a rotating rod rotatably arranged in the mold conveying unit, and the rotating rod is provided with a gear meshing with the arc-shaped rack and a driving motor for driving the rotating rod.

[0009] As a second design scheme of the above-mentioned semi-cylindrical support, the front and rear sides of the semi-cylindrical support are provided with a rotating shaft connected to the conveying seat in the mold conveying unit, and the driving device includes a reducer connected to the rotating shaft, and the reducer is connected to a rotating motor.

[0010] As a first design scheme of the above-mentioned clamping plates, one end of the two clamping plates is arranged in an open shape, and the two clamping plates are connected to the front and rear side surfaces of the semi-cylindrical support through springs and guide slide rods.

[0011] As a second design scheme of the above-mentioned clamping plates, the two clamping plates are connected to the front and rear sides of the semi-cylindrical support through springs and guide slides. Permanent magnets are provided on the clamping plates, and electromagnets are provided on the front and rear sides of the semi-cylindrical support, which are aligned with the upper end of the permanent magnets.

[0012] As a further design scheme of the above, a connecting block is provided on the nozzle mounting plate, the lower end of the telescopic driving member is connected to a rotating connecting seat, the rotating connecting seat and the connecting block are connected by a pin shaft, and the rotating connecting seat is provided with an angle adjustment motor connected to the pin shaft.

[0030] Example 1

[0031] Example 1 discloses a device for automatically applying a release agent to a prefabricated component mold. Figure 1 and attached Figure 2 The main body of the device includes a conveyor base 1 and a control console 2. A feed conveyor 101 and a discharge conveyor 102 are respectively provided at the left and right ends of the conveyor base 1. The feed conveyor 101 and the discharge conveyor 102 can each be configured with a plurality of conveyor rollers or conveyor belts arranged side by side, so that the prefabricated component mold 100 can be conveyed in a directionally controlled manner under the action of the feed conveyor 101 and the discharge conveyor 102.

[0032] Reference Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 A gantry 3 is fixedly mounted on the conveying base 1 between the infeed conveyor 101 and the outfeed conveyor 102. Specifically, a lug 103 is welded to the front and rear sides of the conveying base 1, and the lower ends of the front and rear ends of the gantry 3 are fixedly connected to the lugs 103. A telescopic drive member 4 is mounted on the upper end of the gantry 3. Specifically, the telescopic drive member 4 can be a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod. A spray mechanism 5 is connected to the lower end of the telescopic drive member 4.

[0033] The spraying structure 5 in this embodiment includes a nozzle mounting plate 501, a vertical nozzle 502, and an inclined nozzle 503. The nozzle mounting plate 501 is elongated and positioned perpendicular to the direction of mold transport. Multiple vertical nozzles 502 are then evenly spaced and mounted on the nozzle mounting plate 501, enabling uniform spraying of the bottom wall of the prefabricated component mold 100 during transport. Two inclined nozzles 503 are fixedly mounted at the front and rear ends of the nozzle mounting plate 501, and both inclined nozzles 503 are positioned outward and downward, enabling uniform spraying of the front and rear inner walls and the front and rear bottom corners of the prefabricated component mold 100 during transport. A connecting block 504 is fixed on the upper surface of the nozzle mounting plate 501, and a rotating connecting seat 505 is connected to the lower end of the telescopic driving member 4, and the connecting block 504 and the rotating connecting seat 505 are rotatably connected through a pin shaft. At the same time, an angle adjustment motor 506 is provided on one side of the rotating connecting seat 505, and the angle adjustment motor 506 is connected to the pin shaft, so that the inclination angle of the entire spraying structure 5 can be adjusted under the driving action of the angle adjustment motor 506.

[0034] A release agent storage box 6 is provided on the rear side of the conveying seat 1. The release agent storage box 6 is provided with a dosing pipe to facilitate timely replenishment of release agent and water. At the same time, a stirring device is also provided inside the release agent storage box 6 to achieve uniform mixing of the added release agent and water. Two infusion pumps 7 are provided on the release agent storage box 6, and each infusion pump 7 is connected to an infusion tube 8. The two infusion tubes 8 are then connected to all vertical nozzles 502 and two inclined nozzles 503 in the spraying structure 5, respectively, and a solenoid valve is also provided on each infusion tube 8. In this embodiment 1, through the design of the above-mentioned two infusion pumps 7 and two conveying tubes 8, the vertical nozzles 502 and inclined nozzles 503 in the spraying structure 5 are respectively controlled by different liquid circuits. When spraying different positions of the prefabricated component mold 100, the vertical nozzles 502 and inclined nozzles 503 can be started simultaneously or individually for spraying.

[0035] Reference Attachment Figure 5 and attached Figure 6 A mold clamping and rotating mechanism 9 is provided in the conveying base 1 between the feed conveyor 101 and the discharge conveyor 102. The mold clamping and rotating mechanism 9 includes a semi-cylindrical support 901, an arc-shaped rack 902 is provided on the outer circumferential surface of the lower end of the semi-cylindrical support 901, a rotating rod 903 is provided in the conveying base 1 below the semi-cylindrical support 901, and a gear 904 is provided on the rotating rod 903 to mesh with the arc-shaped rack 902, and then a driving unit 905 for driving the rotating rod 903 to rotate in a certain direction is provided in the conveying base 1. Specifically, the driving unit 905 is composed of a driving motor and a reduction gearbox. The driving motor is connected to the input end of the reduction gearbox, and the rotating rod 903 is connected to the output end of the reduction gearbox. On both the front and rear side surfaces of the semi-cylindrical support 901, a plurality of rollers 906 are uniformly arranged in the circumferential direction with the center axis thereof as the center. Then, arc-shaped roller tracks 907 cooperating with the corresponding rollers 906 are provided on the front and rear inner walls of the conveying base 1. The semi-cylindrical support 901 is driven by the meshing of the gear 904 and the arc-shaped rack 902, and then relies on the guiding effect between the rollers 906 and the arc-shaped roller tracks 907 to realize rotation around its own center axis, so as to adjust the inclination angle of the upper end surface of the semi-cylindrical support 901.

[0036] A row of rollers 908 are rotatably connected to the opening on the upper end face of the semi-cylindrical support 901, and a power unit 909 for rotating the rollers 908 is disposed within the semi-cylindrical support 901. Specifically, the power unit 909 includes a power motor fixed below the rollers 908, a driving pulley disposed at the output of the power motor, and a transmission pulley disposed on the roller shaft at one end of each roller 908. A transmission belt is then disposed between the driving pulley and the transmission pulley. The power input from the power motor and the action of the transmission belt enable the row of rollers 908 to rotate in a directional manner, thereby conveying the prefabricated component mold 100 after spraying to the discharge conveyor device 102 in a directional manner.

[0037] Two clamping plates 910 are symmetrically positioned at the front and rear ends of the semi-cylindrical support 901, located directly above the roller 908. These plates 910 are designed to open in an "eight" shape toward the feed conveyor 101, facilitating the entry of the prefabricated component mold 100 between the two clamping plates 910. A spring 911 and a guide rod 912 are positioned between each clamping plate 910 and the corresponding side surface of the semi-cylindrical support 901. A through-hole aligned with the guide rod 912 is provided on the side surface of the semi-cylindrical support 901. The structural design of this embodiment enables the prefabricated component mold 100 to enter between the two clamping plates 910 under the action of the feed conveyor 101 and be clamped and secured by the force of the springs 911. This ensures that the prefabricated component mold 100 remains stationary during the rotation of the semi-cylindrical support 901, facilitating subsequent application of release agent to the mold's inner wall and the corners of the left and right bottom edges.

[0038] Example 2

[0039] Example 2 discloses a device for automatically applying a release agent to a prefabricated component mold. The overall structural design is the same as that of Example 1. The only difference between Example 2 and Example 1 is the structural design of the mold clamping and rotating mechanism 9. Figure 7 Describe it in detail.

[0040] The mold clamping and rotating mechanism 9 in this second embodiment includes a semi-cylindrical support 901. Rotating shafts 913 connected to the conveying base 1 are disposed on the front and rear sides of the semi-cylindrical support 901, and both rotating shafts 913 coincide with the central axis of the semi-cylindrical support 901. A speed reducer 914 connected to the rotating shaft 913 is also disposed on the conveying base 1, and a rotating motor 915 is connected to the speed reducer 914. The rotating motor 915 and speed reducer 914 control the rotation of the semi-cylindrical support 901 within the conveying base 1, thereby adjusting the inclination angle of the upper end surface of the semi-cylindrical support 901.

[0041] A row of rollers 908 are rotatably connected to the opening on the upper end face of the semi-cylindrical support 901, and a power unit 909 for rotating the rollers 908 is disposed within the semi-cylindrical support 901. Specifically, the power unit 909 includes a power motor fixed below the rollers 908, a driving pulley disposed at the output of the power motor, and a transmission pulley disposed on the roller shaft at one end of each roller 908. A transmission belt is then disposed between the driving pulley and the transmission pulley. The power input from the power motor and the action of the transmission belt enable the row of rollers 908 to rotate in a directional manner, thereby conveying the prefabricated component mold 100 after spraying to the discharge conveyor device 102 in a directional manner.

[0042] Two clamping plates 910 are symmetrically mounted on the front and rear ends of the semi-cylindrical support 901, located directly above the roller 908. A spring 911 and a guide rod 912 are installed between each clamping plate 910 and the corresponding side surface of the semi-cylindrical support 901. A through-hole is provided on the side surface of the semi-cylindrical support 901, aligned with the guide rod 912. Furthermore, a permanent magnet 916 is fixed to each clamping plate 910, and electromagnets 917 are fixed to the front and rear inner walls of the semi-cylindrical support 901. These electromagnets 917 are aligned with the permanent magnets 916 and, when energized, generate a repulsive force against the permanent magnets 916.

[0043] The above-mentioned structural design of this embodiment enables the prefabricated component mold 100 to enter between the two clamping plates 910 under the action of the feeding and conveying device 101, and then current is passed to the electromagnet 917. The two clamping plates 910 are brought close to each other by the action of the magnetic field force to clamp the prefabricated component mold 100. Moreover, the clamping force of the two clamping plates 910 on the prefabricated component mold 100 can be achieved by the magnetic force, thereby ensuring that the prefabricated component mold 100 can remain stationary during the rotation of the semi-cylindrical support 901, which facilitates the subsequent spraying of the release agent on the inner wall of the mold and the ridge corners at the bottom of the left and right ends.

[0044] 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 scope of protection of the present invention.
