Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cement pole production, in particular to a mold release agent spraying station. Background Art
[0002] The production of cement poles uses molds. After the steel cage is set in the mold, concrete is poured into the mold. After the mold is closed, it is rotated at high speed by a centrifuge to form the pole structure inside the mold. The finished cement pole is then obtained after curing such as steaming.
[0003] In order to facilitate the demoulding of the mold after the steaming and other curing processes are completed, during the production process, before the steel cage is placed into the mold, it is necessary to clean the mold, and then spray a layer of release agent on the inner surface after cleaning. Utility Model Content
[0004] The purpose of the utility model is to propose a mold release agent spraying station, which is used for performing a mold release agent spraying operation on the inner surface of a mold during the production process of cement poles.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A mold release agent spraying station includes a frame for support; a nozzle with a downward spraying direction is provided on one side of the frame; a mounting bracket connected to the frame is provided behind the nozzle, the mounting bracket extends downward, and a smear ball is provided at the lower end of the mounting bracket, and a smear layer of soft material is provided on the circumference of the smear ball; a collection trough with an upward opening is provided directly below the smear ball.
[0007] On the basis of the above solution and as a preferred solution of the above solution: the nozzle is arranged to be tilted downward, and the tilt direction of the nozzle is toward a direction away from the smear ball.
[0008] On the basis of the above solution and as a preferred solution of the above solution: a connecting port communicating with the inside of the tank is provided on the bottom side of the collecting tank, and a switch valve is provided on the connecting port.
[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: a rotatable shaft is horizontally provided at the lower end of the mounting bracket, the axis of the shaft is perpendicular to the vertical plane in which the nozzle and the smear ball are located, the smear ball is fixedly strung on the shaft, and a drive motor is provided on the mounting bracket to be transmission-connected to the shaft.
[0010] On the basis of the above solution and as a preferred solution of the above solution: the driving motor is a speed-regulating motor.
[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the upper end of the mounting bracket is fixedly connected to the frame body, and the lower end of the mounting bracket is provided with a U-shaped bracket with an opening facing downward; the two ends of the rotating shaft are respectively connected to the ends at the opening of the U-shaped bracket through bearing seats; the smear ball is arranged on the rotating shaft in the groove of the U-shaped bracket; a first transmission wheel is provided at one end of the rotating shaft, and a second transmission wheel is provided on the output shaft of the drive motor, and the first transmission wheel and the second transmission wheel are connected by an annular transmission belt.
[0012] On the basis of the above solution and as a preferred solution of the above solution: the smear ball includes a base body, and the smear layer is composed of a plurality of cloth strips connected to the base body.
[0013] In order to be able to perform release agent spraying operation on the inner surface of the mold during the production process of cement poles, the utility model has the following beneficial effects:
[0014] During use, conveyors for conveying the mold can be set up in front and behind the mold release agent spraying station, and the mold can be transported by the conveyor so that it passes directly under the nozzle and the coating ball in a straight line. In the process of the mold moving and passing through the mold release agent spraying station, any part of the inner cavity of the mold first passes directly under the nozzle, and then passes directly under the coating ball. In the process of the mold passing directly under the nozzle, the nozzle continuously sprays the release agent so that the release agent covers the inner surface of the release agent. Then, when the mold passes directly under the coating ball, the coating ball with a downward protruding part can be partially embedded in the groove of the mold, so that the coating layer of the coating ball can contact the inner surface of the mold. In the process of the mold moving, its inner surface can slide relative to the coating layer. During the sliding process, the coating layer can evenly spread the release agent sprayed on the inner surface of the mold.
[0015] It is worth noting that during the actual spraying process of release agent, in order to ensure the spraying effect of the release agent, the spraying volume is usually relatively large. This will cause the release agent to accumulate in the mold and form excess release agent that can flow at the bottom of the mold. At this time, when the applicator ball passes through the inner groove of the mold, it not only evenly spreads the release agent on the mold, but also pushes the accumulated release agent outward and discharges it from the mold. The release agent discharged from the mold can be collected by the collection tank.
[0016] Among them, in the process of cleaning the release agent accumulated in the mold with the smear ball, the excess impurities in the mold can also be cleaned for a second time.
[0017] Among them, the soft characteristics of the coating layer ensure the fit between the coating ball and the inner side of the mold, further ensuring the coating effect on the demoulding machine and the discharge effect of the accumulated release agent.
[0018] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] See Figure 1-4 The utility model discloses a mold release agent spraying station, which can be used to spray the release agent on the inner surface of the mold 600 during the production process of cement poles.
[0025] In the embodiment of the present disclosure, Figure 1 As shown, the mold release agent spraying station includes a support frame 100. A nozzle 200 with a spray direction facing downward is provided on one side of the frame 100. The nozzle 200 is used to spray the release agent on the inner surface of the mold 600. In order to have a better spraying effect, Figure 2 As shown, the nozzle 200 is tilted downward, away from the smear ball 300. A mounting bracket 101 is located behind the nozzle 200 and connected to the frame 100. The mounting bracket 101 extends downward, and the smear ball 300 is located at its lower end. A soft coating layer 301 is provided around the smear ball 300. A collection tank 400, opening upward, is located directly below the smear ball 300.
[0026] like Figure 4As shown, during use, conveyors for transporting the mold 600 can be set up in front of and behind the mold release agent spraying station. Under the conveyor, the mold 600 can pass directly under the spray head 200 and the smear ball 300. During the process of the mold 600 moving and passing through the mold release agent spraying station, any part of the inner cavity of the mold 600 first passes directly under the spray head 200 and then passes directly under the smear ball 300. When the mold 600 passes directly under the nozzle 200, the nozzle 200 continuously sprays the release agent so that the release agent covers the inner surface of the release agent. Then, when the mold 600 passes directly under the coating ball 300, the coating ball 300 with a downward protruding part can be partially embedded in the groove of the mold 600, so that the coating layer 301 of the coating ball 300 can contact the inner surface of the mold 600. During the movement of the mold 600, its inner surface can slide relative to the coating layer 301. During the sliding process, the coating layer 301 can evenly spread the release agent sprayed on the inner surface of the mold 600.
[0027] It is worth noting that during the actual spraying of the release agent, a relatively large amount is usually sprayed to ensure the spraying effect of the release agent. This can cause the release agent to accumulate in the mold 600, forming excess release agent that can flow at the bottom of the mold 600. At this time, as the smearing ball 300 slides across the groove in the mold 600, it not only evenly spreads the release agent on the mold 600, but also pushes the accumulated release agent outward and discharges it from the mold 600. The release agent discharged from the mold 600 can be collected by the collection tank 400.
[0028] In the process of cleaning the release agent accumulated in the mold 600 , the smear ball 300 can also perform a secondary cleaning of excess impurities in the mold 600 .
[0029] Among them, the softness of the coating layer 301 ensures the fitting effect between the coating ball 300 and the inner side of the mold 600, further ensures the coating effect on the demoulding machine, and also ensures the discharge effect of the accumulated release agent.
[0030] In the embodiment of the present disclosure, in order to facilitate the recovery of the collected release agent, a connection port 401 communicating with the tank is provided on the bottom side of the collection tank 400, and a switch valve 402 is provided on the connection port 401. When the switch valve 402 is opened, the release agent in the collection tank 400 can be discharged and recovered.
[0031] Among them, the smear ball 300 was replaced by a mop in the test. After actual application, although the mop can basically meet the smearing needs, it is still not ideal for cleaning the accumulated release agent. In view of this, the following improvement is made: a rotatable shaft 302 is horizontally provided at the lower end of the mounting bracket 101, and the axis of the shaft 302 is perpendicular to the vertical plane where the nozzle 200 and the smear ball 300 are located. The smear ball 300 is fixedly arranged on the shaft 302, and a drive motor 500 is provided on the mounting bracket 101 to be connected to the shaft 302 for transmission. The rotating smear ball 300 acts on the inner side of the mold 600 to improve the working effect in various aspects. Furthermore, the drive motor 500 is a speed-regulating motor, and the rotation speed of the smear ball 300 can be controlled by the speed-regulating motor.
[0032] In order to meet the reliability and stability of the functional structure, the upper end of the mounting bracket 101 is fixedly connected to the frame body 100, and the lower end of the mounting bracket 101 is provided with a U-shaped bracket 102 with an opening facing downward; the two ends of the rotating shaft 302 are respectively connected to the ends of the opening of the U-shaped bracket 102 through the bearing seat 103; the smear ball 300 is arranged on the rotating shaft 302 in the groove of the U-shaped bracket 102; a first transmission wheel 501 is provided at one end of the rotating shaft 302, and a second transmission wheel 502 is provided on the output shaft of the driving motor 500, and the first transmission wheel 501 and the second transmission wheel 502 are connected by an annular transmission belt 503.
[0033] like Figure 3 As shown, the smear ball 300 includes a base 303, which is fixedly mounted on a rotating shaft 302. The smear layer 301 is composed of a plurality of cloth strips 304 connected to the base 303. The cloth strips 304 are preferably cotton cloth strips 304, which have better smearing and cleaning effects.
[0034] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
