Description

Technical Field

[0001] The present invention belongs to the technical field of caulking agent production equipment, and particularly relates to a caulking agent pressing method. Background Art

[0002] In house decoration construction, tiles, marbles, etc. are used to pave the floor and walls. After the tiles or marbles are paved, there will be gaps between adjacent tiles or adjacent marbles, and the caulking agent is a decorative material used to fill these gaps.

[0003] The caulking agent is a fluid or paste-like building material produced by a specialized factory. In decoration, to make the caulking agent for caulking have a color matching the tiles or marbles, it is necessary to mix the caulking agents of basic colors produced by the factory according to a set ratio. The mixing method is to first pour several caulking agents of basic colors with set mass ratios into a mixing tank and stir them with a vacuum mixing device. After being stirred evenly, it is also necessary to use a dispensing and filling device to fill the mixed caulking agent in the mixing tank into the caulking agent dispensing cylinder.

[0004] In the dispensing and filling device, the fluid or paste-like caulking agent in the mixing tank is extruded and pushed out through a filling channel at the bottom of the mixing tank by a pushing disc driven by a pressing mechanism and filled into the caulking agent dispensing cylinder. To improve the pushing reliability of the pushing disc during filling and prevent the material from overflowing along the gap between the pushing disc and the inner wall of the mixing tank, in the prior art, grooves are formed on the circumferential surface of the pushing disc, and rubber rings are arranged in the grooves. However, in this structure, during the actual pressing process of the caulking agent, after the pushing disc enters the interior of the mixing tank, due to the rubber ring, a seal is formed between the pushing disc and the inner wall of the mixing tank, which causes the air in the space above the caulking agent in the mixing tank to be unable to be discharged. As the pushing disc descends, the pressure of this part of the air that cannot be discharged in the mixing tank will become larger and larger, and forcibly driving the pushing disc will cause damage to the mixing tank, the pushing disc, and even the pressing mechanism. Therefore, someone thought of opening exhaust holes on the pushing disc to allow the air to be discharged from the exhaust holes before the pushing disc presses the caulking agent. Although this can discharge the air above the caulking agent in the mixing tank, the opening of the exhaust holes causes a small amount of caulking agent to overflow from the exhaust holes during the process of the pushing disc pushing the caulking agent, which not only reduces the pushing reliability, but also the caulking agent will adhere to the pushing disc and the exhaust holes, polluting the pushing disc, and making the pushing disc need to be cleaned every time a pressing operation is performed, increasing the workload of the workers. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a caulking agent pressing method with reliable pushing, which can not only discharge the air in the mixing tank during the pushing process, but also keep the pushing disc clean, so as to overcome the defects of the prior art.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A method for pressing and filling a caulking agent, in which a caulking agent in a stirring tank is pushed by a dispensing and filling device through a filling channel at the bottom of the stirring tank and filled into a caulking agent dispensing cylinder. The dispensing and filling device includes a pushing disc and a pressing mechanism for driving the pushing disc to press down. The diameter of the pushing disc is slightly smaller than the inner diameter of the stirring tank. The dispensing and filling device further includes a covering film and an extrusion rubber strip. The steps of the method for pressing and filling the caulking agent are as follows:

[0008] S101: Place the stirring tank filled with the caulking agent directly below the pushing disc, cover the surface of the caulking agent in the stirring tank with the covering film, and place a circle of extrusion rubber strips along the inner wall of the stirring tank on the upper surface of the covering film. Then, sleeve the caulking agent dispensing cylinder on the filling channel.

[0009] S102: The pressing mechanism drives the pushing disc to descend into the stirring tank. Before the pushing disc presses on the caulking agent, the air in the stirring tank is discharged from the gap between the pushing disc and the inner wall of the stirring tank. When pressing on the caulking agent, the edge of the pushing disc presses on the extrusion rubber strip. Then, the pressing mechanism continuously drives the pushing disc to push the caulking agent in the stirring tank, so that the caulking agent is filled into the caulking agent dispensing cylinder through the filling channel.

[0010] By adopting the above technical solution, since the diameter of the pushing disc is slightly smaller than the inner diameter of the stirring tank, there is a gap between the pushing disc and the inner wall of the stirring tank. During the downward pressing process of the pushing disc, before pressing on the upper surface of the caulking agent, the air in the stirring tank can be discharged from the gap. When contacting the upper surface of the caulking agent, there will be no air between the pushing disc and the caulking agent. In addition, the edge of the pushing disc pressing on the pressing rubber strip can scrape the caulking agent on the inner wall of the stirring tank clean, and the use of the covering film can prevent the pushing disc from being stained with the caulking agent and avoid being contaminated by the caulking agent.

[0011] Therefore, the method for pressing and filling the caulking agent of the present invention has the advantages of reliable pushing, being able to discharge the air in the stirring tank during the pushing process, and keeping the pushing disc clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The caulking agent pressing method of the present invention is applied in the caulking agent color mixer as Figure 1 shown. To clearly illustrate the caulking agent pressing method of the present invention, the structure of the caulking agent color mixer will be introduced in detail in this specific implementation manner.

[0018] The caulking agent color mixer includes a frame 100, a vacuum mixing device 200 and a dispensing and filling device 300 provided on the frame 100.

[0019] Among them, the frame 100 includes a tabletop 101, a cabinet 102 located below the tabletop 101, two slide rails 103 provided on the tabletop 101, a first bracket 1051 and a second bracket 1052 provided on the tabletop 101. The slide rails 103 extend from a position below the first bracket 1051 to a position below the second bracket 1052. A support seat 104 capable of moving along the slide rails 103 is also provided on the slide rails 103.

[0020] The vacuum mixing device 200 includes a mixing tank 210, a mixer 220, a vacuum pump 230 and a lifting mechanism 240. The lifting mechanism 240 is installed on the first bracket 1051, and the mixer 220 is installed on the lifting mechanism 240 and can rise and fall under the drive of the lifting mechanism 240. The lifting mechanism 240 can be an electric lifting mechanism, a cylinder lifting mechanism or a hydraulic lifting mechanism. In this embodiment, the lifting mechanism 240 is preferably a screw-nut lifting mechanism driven by a motor. The vacuum pump 230 is placed in the cabinet 102.

[0021] The mixer 220 includes a sealing cover 221, a mixing motor 222 provided above the sealing cover 221, and a mixing head 223 provided below the sealing cover 221.

[0022] Among them, the mixing tank 210 is a stainless steel tank with a thickness resistant to vacuum strength. The top of the mixing tank 210 is open, and the bottom has a filling channel 211 communicating with the inside of the tank. A filling control valve 212 is provided on the filling channel 211. The filling control valve 212 can be a manual valve, an electromagnetic valve or a pneumatic valve. For the convenience of workers' operation, it can also be a foot-operated electromagnetic valve or a foot-operated pneumatic valve. In addition, handles 213 are also provided on the outer walls on both sides of the mixing tank 210. The handles 213 facilitate the handling and movement of the mixing tank 210.

[0023] The sealing cover 221 is provided with a gas passage 2211, and the gas passage 2211 is connected to a vacuum pump 230 through a gas pipeline 2212. A vacuum control valve 2213 and a pressure gauge 2214 are arranged on the gas pipeline 2212. Among them, the vacuum control valve 2213 is used to control the connection between the vacuum pump 230 and the gas passage, and it can be a manual valve, a solenoid valve or a pneumatic valve. A sealing ring is arranged on the lower surface of the sealing cover 221, and when the sealing cover 220 covers the top opening of the mixing tank 210, it can seal the mixing tank 210.

[0024] When stirring is required, pour the joint sealant of various basic colors with the prepared mass ratio into the mixing tank 210, then place the mixing tank 210 on the support seat 104 and move it to directly below the sealing cover 221. Driven by the lifting mechanism 240, the sealing cover 221 can press and fix the mixing tank 221 on the table 101 and block the top opening of the mixing tank 221. Then start the stirring motor 222 and the vacuum pump 230, so that while evacuating the inside of the mixing tank 210, stir and mix the joint sealant of various basic colors inside the mixing tank 210. When the mixing is sufficient to form a new color and no bubbles emerge, stop stirring and evacuating. The pressure gauge 2214 is used to observe the vacuum degree inside the mixing tank 210 during evacuation. In this embodiment, the gas pipeline 2211 is also connected to an exhaust pipe 2216, and an exhaust valve 2217 is arranged on the exhaust pipe 2216. The function of the exhaust pipe 2216 and the exhaust valve 2217 is that when the sealing cover 221 needs to be separated from the mixing tank 210, by opening the exhaust valve 2216, the vacuum environment inside the mixing tank 210 can be broken, so that the sealing cover 221 can be easily separated from the mixing tank 210 under the drive of the lifting mechanism. Of course, in other embodiments, an exhaust hole can also be directly opened on the sealing cover, and the exhaust valve 2217 can be directly arranged on the exhaust hole. The exhaust valve 2217 can be a manual valve, a solenoid valve or a pneumatic valve.

[0025] In addition, two eyepieces 2215 are also arranged on the sealing cover 220. One of the eyepieces 2215 is used for lighting with a lamp, and the other eyepiece is used for visual observation. By observing through the eyepiece 2215, the mixing situation of the joint sealant in the mixing tank 210 and the bubble discharge situation can be understood. Of course, in other embodiments, a lighting lamp can be directly fixed on one of the eyepieces, so that there is no need to hold the lighting lamp by hand.

[0026] As Figure 3As shown, the support base 104 is composed of a chassis 1041 and an annular edge 1042 provided at the edge of the chassis 1041. The annular edge 1042 has a notch 1043 at the position facing the second support 1052. When the mixing tank 210 is placed on the support base 104, its filling pipe 211 can just extend out from the notch 1043. The function of the support base 104 is to be arranged on the slide rail 103 to carry the mixing tank 210, so that the mixing tank 210 can slide back and forth between the mixer 220 and the dispensing and filling device 300 along the slide rail 103 on the support base 104. In other embodiments, the support base 104 can be driven to move on the slide rail 103 by a motor, a cylinder or a hydraulic cylinder.

[0027] As Figure 2 shown, the dispensing and filling device 300 is arranged above the slide rail 103 and includes a pressing mechanism 310 and a pushing disc 320.

[0028] Among them, the pressing mechanism 310 can be a hydraulic pressing mechanism, a pneumatic pressing mechanism or an electric pressing mechanism. In this embodiment, the pressing mechanism 310 is a hydraulic cylinder 311 vertically fixed on the second support 1052 and a hydraulic station 312 connected to the hydraulic cylinder 311 through a hydraulic pipeline. The hydraulic station 312 is placed in the cabinet 102. The hydraulic cylinder 311 has a piston rod extending downward, and the pushing disc 320 is fixed to the lower end of the piston rod of the hydraulic cylinder 311.

[0029] Combined Figure 4 with Figure 5 shown, the dispensing and filling device 300 further includes a covering film 321 and an extrusion rubber strip 322. The extrusion rubber strip 322 is preferably a rubber strip with a circular cross-section. The lower surface of the pushing disc 320 has a ring-shaped step notch 323 at the periphery. The diameter of the pushing disc 320 is slightly smaller than the inner diameter of the mixing tank 210.

[0030] Again, as Figure 1 shown Figure 2 and

[0031] The method for pressing the sealant of the present invention is as follows:

[0032] When dispensing is required, the mixing tank 210 containing the color-mixed and stirred sealant 10 is pulled along the slide rail 103 to the position directly below the pushing disc 302 by pulling the handle 213. The covering film 321 is covered on the upper surface of the sealant 10 in the mixing tank 210, and an extrusion rubber strip 322 is placed along the inner wall of the mixing tank 210 on the covering film 321, and then the sealant dispensing cylinder is sleeved on the outlet of the filling channel 211.

[0033] Open the filling control valve 212, start the upper pressing mechanism 310, and drive the pushing disc 320 into the interior of the mixing tank 210. Since the diameter of the pushing disc 320 is slightly smaller than the inner diameter of the mixing tank 210, there is a gap 324 between the pushing disc 310 and the inner wall of the mixing tank 210. During the downward pressing of the pushing disc 320, before pressing onto the upper surface of the sealant 10, the air in the mixing tank 210 can be discharged from the gap 324. When it comes into contact with the upper surface of the sealant 10, there will be no air between the pushing disc 310 and the sealant 10. Among them, the existence of the stepped notch 323 enables the lower surface of the pushing disc 320 to contact the covering film 321 covering the upper surface of the sealant 10 and fully press on the sealant. On the other hand, this notch 323 can also hold the extrusion rubber strip 322, enabling the extrusion rubber strip 322 to closely adhere to the inner wall of the mixing tank 210 and scrape the sealant 10 on the inner wall of the mixing tank 210 clean during the downward pressing process. The use of the covering film 321 can prevent the pushing disc 320 from being stained with the sealant and avoid being contaminated by the sealant.

[0034] As the pushing disc 320 is pressed downward, the sealant 310 in the mixing tank 210 will flow out from the filling channel 211 and be poured into the sealant dispensing cylinder. When a sealant dispensing cylinder is filled, close the filling control valve 212. At this time, the sensor in the hydraulic cylinder 311 will sense an increase in resistance and feedback it to the hydraulic station, and the hydraulic station will control the hydraulic cylinder to maintain the balance between pressure and resistance and not drive the pushing disc 310 to press downward.

[0035] Subsequently, continue to put a new empty sealant dispensing cylinder on the outlet of the filling channel 211, and then open the filling control valve 212 again. At this time, the sensor in the hydraulic cylinder 311 will sense a decrease in resistance and feedback it to the hydraulic station, and the hydraulic station will continue to control the hydraulic cylinder 311 to apply pressure to the pushing disc 320, so that the pushing disc 320 extrudes the sealant again and pours it into the new empty sealant dispensing cylinder.

[0036] Repeat this cycle until all the sealant in the mixing barrel is extruded and dispensed into each sealant dispensing cylinder.

[0037] As Figure 2 shown, in addition, an enhanced cushion block 1033 is also provided directly below the pushing disc 320 on the tabletop. The function of this enhanced cushion block 1033 is that during dispensing, move the support seat 104 above the enhanced cushion block 1033, and support the lower surface of the support seat 104 through the enhanced cushion block 1033, so as to avoid deformation of the mixing tank 210 and the support seat 104 when pushing the sealant 10 in the mixing tank 210 and protect the guide rail 104 and the sliding feet of the support seat 104 from being damaged.

[0038] In the present invention, the stirring tank and the dispensing and filling device constitute a caulking agent pressing device.
