Description

Technical Field

[0001] The invention belongs to the field of coating production, and in particular relates to a process and equipment for switching production between real stone paint and imitation stone paint. Background Art

[0002] Both real stone paint and imitation stone paint are paints with decorative effects similar to marble and granite. They are mainly made of natural stone powder of various colors and are used to create imitation stone effects on building exterior walls.

[0003] Real stone paint and imitation stone paint are two commonly used architectural paints. There are some differences between them in terms of composition, appearance, application, performance, etc.

[0004] Real stone paint, also known as natural stone paint, its main component is natural stone particles (such as stone powder, stone sand, etc.), mixed with resin, pigment and other additives. Due to the use of natural materials, real stone paint has good environmental protection, weather resistance, wear resistance, stronger durability and UV resistance, and a longer maintenance cycle; while imitation stone paint is usually made of synthetic resin and artificially synthesized pigments, fillers, etc. to simulate the appearance of stone. Its ingredients are mostly chemical synthetics and may not have the ingredients of natural stone. Although it also has certain weather resistance, it may fade or age after long-term use compared to real stone paint. The prices of the two are also different.

[0005] Therefore, when producing real stone paint and imitation stone paint, the main difference lies in the different mixers used. Since real stone paint contains more natural stone particles, it requires stronger shear force and mixing uniformity, so a horizontal mixer is more suitable. The components of imitation stone paint are mainly synthetic resins and fine pigments, and a vertical mixer can mix them quickly and effectively. Therefore, traditional workshops often have two independent production lines for the classified production of real stone paint and imitation stone paint, which occupies a larger area and requires more operators to take care of the two production lines. Summary of the invention

[0006] In view of the above defects, the present invention provides equipment for switching production of real stone paint and imitation stone paint, including a horizontal mixer and a vertical mixer for mixing and stirring raw materials, the horizontal mixer and the vertical mixer are respectively connected to two raw material bins through a real stone paint material pipe and an imitation stone paint material pipe, and are respectively used for mixing and stirring the raw materials of real stone paint and imitation stone paint, and the horizontal mixer and the vertical mixer are respectively equipped with a dust removal device for reducing pollution, a water injection device for anti-dry spraying and for cleaning after operation, and a plurality of dust removal devices and water injection devices are connected through a shunt delivery pipe, which are respectively used for exhausting air and delivering water;

[0012] Furthermore, the water injection device includes an external water pump and two arc-shaped plates adapted to the connected top seat, the two arc-shaped plates are respectively installed on both sides of the bottom of the top seat, the front and rear ends of each arc-shaped plate are installed with slide rails, each slide rail is installed with an electric slider, and each electric slider is movably installed at the end corner on the same side of the top seat through a hinged rod;

[0013] Temporary storage bins are provided inside the two arc-shaped plates, and water inlet pipes connected to the temporary storage bins are installed at the ends of the two arc-shaped plates away from each other. Water outlet valves are installed at the left and right ends of the top filter plate, and the two water outlet valves are respectively used to connect with the two water inlet pipes. Several water outlet nozzles are installed on the bottom surface of the arc-shaped plates. Contact switches are installed at the ends of the two arc-shaped plates close to each other, and a mobile power supply for powering the contact switch and a wireless module for outputting signals from the contact switch are installed on the arc-shaped plates.

[0014] Furthermore, an electric heating plate for heating the temporary storage bin is installed on the top of the arc-shaped plate.

[0016] Furthermore, the inner tube is connected to the water outlet valves on both sides of the filter plate at the bottom through two diversion pipes, and the two diversion pipes are respectively placed in pipe grooves reserved on the top of the middle partition plate.

[0017] Furthermore, a plastic curtain for sealing is hung at the bottom of the dust removal device, and the plastic curtain is respectively mounted on the four hinged rods through four hanging holes;

[0018] The plastic curtain is formed by heat pressing four EVA films, and a magnet is fixed at the bottom for magnetic attraction with the outer chassis of the horizontal mixer or vertical mixer.

[0019] The present invention also includes a production process for the above-mentioned real stone paint and imitation stone paint switching production equipment, which specifically includes the following process flow:

Embodiments of the device are given in the drawings. However, the device can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0046] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0047] Example

[0048] like Figure 1-3 As shown, this embodiment provides a device for switching production of real stone paint and imitation stone paint, including:

[0049] A horizontal mixer 1 and a vertical mixer 2 are used for mixing and stirring raw materials. The horizontal mixer 2 and the vertical mixer 1 are connected to two raw material bins through a real stone paint material pipe and an imitation stone paint material pipe, respectively, and are used for mixing and stirring the raw materials of real stone paint and imitation stone paint, respectively. The horizontal mixer 1 and the vertical mixer 2 are respectively equipped with a dust removal device 3 for reducing pollution, and a water injection device 5 for anti-dry spraying and post-operation cleaning. Several dust removal devices 3 and water injection devices 5 are connected by a diversion delivery pipe, respectively used for exhausting air and delivering water;

[0050] In detail, the flow distribution pipe is an inner pipe 7 and an outer pipe 6, the inner pipe 7 is placed inside the outer pipe 6, the inner pipe 7 is used to communicate with the external water source, and the outer pipe 6 is used to communicate with the input end of the industrial dust collection equipment, that is, the inner pipe 7 and the outer pipe 6 have a certain hardness and good support, and there is a sufficient channel for dust collection between the outer pipe 7 and the inner pipe 6;

[0051] The dust removal device 3 includes an external industrial dust collection device and a top seat 31. An inner bin is provided at the bottom of the top seat 31. A middle partition 32 is installed in the inner bin. A filter plate 35 is provided at the bottom of the middle partition 32 to prevent debris from entering the industrial dust collection device. The filter plate 35 is installed at the bottom of the top seat 31 by screws to support the middle partition 32. A socket 33 for the outer tube 6 to penetrate is provided in the middle of the middle partition 32. The industrial dust collection device can be operated normally, that is, the raw materials floating in the air during the mixing process can be recycled.

[0052] The water injection device 5 includes an external water pump and two arc-shaped plates 51 adapted to the top seat 31 connected thereto. The two arc-shaped plates 51 are respectively installed on both sides of the bottom of the top seat 31. The front and rear ends of each arc-shaped plate 51 are installed with a slide rail 54. Each slide rail 54 is installed with an electric slider 6. Each electric slider 6 is movably installed at the end corner on the same side of the top seat 31 through a hinge rod 4. At the same time, the hinge rod 4 can be hinged through a pin shaft with a damping mechanism. The position of the two arc-shaped plates 51 can be adjusted at any time when it is needed later.

[0053] Temporary storage bins are provided inside the two arc-shaped plates 51, and water inlet pipes 52 connected to the temporary storage bins are installed at the ends of the two arc-shaped plates 51 away from each other. Water outlet valves 36 are installed at the left and right ends of the top filter plate 35. The two water outlet valves 36 are respectively used to communicate with the two water inlet pipes 52. It should be noted that in order to realize that the water inlet pipe 52 can be automatically connected with the water outlet valve 36 after the two arc-shaped plates 51 move, and have good sealing performance, this can be achieved through the following structure:

[0054] 1) A nipple-shaped rubber water outlet pipe is installed on the valve head of the water outlet valve 36. The nipple head is made of pure rubber and has a water channel in the middle. A PET pipe is installed inside the nipple handle to increase the hardness of this part, that is, when the nipple head moves, it can smoothly enter the inside of the water inlet pipe 52. As the water flows through the water channel, the nipple head will expand, so that the outside of the nipple head fits with the inner circle of the water inlet pipe 52, which plays a good sealing function (this structure is adopted in this embodiment);

[0055] 2) A hose and an electric push rod are installed on the valve head of the water outlet valve 36. The electric push rod is fixed on the hose by a pipe ring. When the contact switch 57 is triggered, the signal is transmitted to the water pump. At the same time, a processor is installed on the electric push rod to synchronously receive the signal, so that the electric push rod drives the hose to move downward and insert into the water inlet pipe 52 to achieve communication;

[0056] It can also be realized by using a tapered tube, a self-locking structure and other structures, which will not be described here, and can be selected according to needs;

[0057] A plurality of water nozzles 58 are installed on the bottom surface of the arc plate 51. A contact switch 57 is installed at one end of the two arc plates 51 close to each other. A mobile power supply for supplying power to the contact switch and a wireless module 56 for outputting signals from the contact switch are installed on the arc plate 51 (having a certain heat insulation effect by installing a heat insulation board, etc.). A rubber pad 55 is also installed at one end of the arc plate 51 where the contact switch 57 is installed to protect the contact switch 57.

[0058] The inner tube 7 is connected to the water outlet valves 36 on both sides of the bottom filter plate 35 through two shunt pipes 8. The two shunt pipes 8 are respectively placed in the pipe grooves 34 reserved on the top of the middle partition plate 32, so as to realize water supply to the two arc plates 51 respectively.

[0059] In addition, an electric heating plate 53 for heating the temporary storage bin is installed on the top of the arc plate 51. When the raw materials adhere to the wall and are inconvenient to clean, the electric heating plate 53 can be started to heat the water flow, which is convenient for cleaning the inside of the mixer.

[0060] The water outlet nozzle 58 includes an atomizing nozzle and a high-pressure nozzle which are distributed at intervals. The atomizing nozzle is used to ensure the humidity of the raw material during the mixing operation to prevent it from being too dry, while the high-pressure nozzle is used for cleaning during the subsequent replacement of the raw material during mixing;

[0061] A sand mill for finely grinding the raw materials mixed by the horizontal mixer 1 and the vertical mixer 2;

[0062] A mixing kettle for mixing finely ground raw materials with additives;

[0063] and a filling machine for filling.

[0064] In addition, in order to prevent dust leakage, spraying, and atomization leakage, a plastic curtain 9 for sealing is hung at the bottom of the dust removal device 3. The plastic curtain 9 is respectively mounted on the four hinge rods 4 through four hanging holes 92.

[0065] The plastic curtain 9 is formed by hot pressing four EVA films 91, and a magnet 93 is fixed at the bottom for magnetic attraction with the outer case of the horizontal mixer 1 or the vertical mixer 2, and its function is to ensure the sealing during the operation, and it has good sealing performance whether it is dust removal or cleaning.

[0066] In addition, it should be noted that when the electric slider is working, the switch of the industrial vacuum equipment will be disconnected (which can be achieved through a PLC controller) to prevent the collected raw materials from agglomerating due to the intake of moisture.

[0067] When it is necessary to produce real stone paint and imitation stone paint simultaneously:

[0068] S1. Using a screening machine, the raw materials of real stone paint and imitation stone paint are screened and prepared for use;

[0069] S2, the raw materials of real stone paint are added into the horizontal mixer 1, and the raw materials of imitation stone paint are added into the vertical mixer 2, and each is mixed, and the horizontal mixer 1 and the vertical mixer 2 are used to mix the real stone paint and the imitation stone paint respectively;

[0070] S3, refining by sand mill;

[0071] S4, weighing and mixing through a mixing tank;

[0072] S5, adding additives to the raw materials of real stone paint and mixing them through a mixing kettle;

[0073] S6. Filling is performed by a filling machine.

[0074] When producing imitation stone paint alone:

[0075] S1, screening the raw materials of the imitation stone paint by a screening machine and preparing them for use;

[0076] S2, the raw materials of the imitation stone paint are added into the horizontal mixer and the vertical mixer, and each is mixed;

[0077] After the horizontal mixer 1 has been used for the production of real stone paint, it needs to be cleaned. First, the electric sliders at each horizontal mixer 1 are controlled to move synchronously. The electric sliders on both sides drive the arc plates 51 on both sides to move closer to each other at the slide rails 54 (the slide rails 54 are arc-shaped) until the two stop moving after contact (the one-way movement length control can be achieved through PLC). At this time, the rubber pad 55 is squeezed, and the contact switch 57 located in the reserved groove of the rubber pad 55 is triggered by the deformed rubber pad 55. The corresponding contact switch 57 is transmitted to the processor controlling the water pump through the wireless module 56 to turn on the switch of the water pump and put it in a strong pressure state (that is, the maximum delivery power). The water source is delivered to each inner tube 7 through the water pump, and then delivered to the bottom arc plate 51 through the diverter pipe 8. Due to the injection of high-pressure water flow, the water output of each high-pressure nozzle will be met, so that the inside of the horizontal mixer and the vertical mixer is sprayed with water, and then the cleaning work is achieved through the stirring mechanism inside the horizontal mixer and the vertical mixer.

[0078] S3, refining by sand mill;

[0079] S4, weighing and mixing through a mixing tank;

[0080] S5. Filling is performed by a filling machine.

[0081] It should be noted that the structure described in the present invention can be implemented in a variety of different forms and is not limited to the described embodiments. Any equivalent transformations made by ordinary technicians in this field using the contents of the present invention description and drawings, or directly or indirectly applied to other related technical fields, such as the loading and unloading of other items, are included in the protection scope of the present invention.
