Description

Technical Field

[0001] This utility model relates to a high-efficiency polishing machine for terrazzo surfaces. Background Technology

[0002] After terrazzo flooring is poured and formed, it needs to be ground and then polished to make it smooth and free of particles.

[0003] In existing technology, polishing is done using a specialized floor polishing machine. During the operation of the polishing machine, polishing agent needs to be added to the polishing area. The polishing agent participates in the polishing process and plays multiple roles in the polishing process of terrazzo (or stone, flooring), such as improving gloss, repairing the surface, and enhancing durability.

[0004] In the existing technology, the polishing agent needs to be applied manually. After manual application, the polishing machine is pushed to the application position for polishing. This operation method is relatively troublesome and has low operating efficiency. Especially when working alone, in order to avoid polishing the machine in place, the polishing machine needs to be turned off when applying the polishing agent. After the polishing agent is applied, the polishing machine is restarted.

[0005] To address this, we upgraded existing polishing machines and designed a high-efficiency polishing machine for terrazzo surfaces that can automatically coat the polishing process during polishing, thereby improving polishing efficiency. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a high-efficiency polishing machine for terrazzo surfaces that can automatically coat the polishing machine during the polishing process, thereby improving the polishing efficiency.

[0007] To solve the above problems, the present invention adopts the following technical solution: A high-efficiency polishing machine for terrazzo surfaces includes a frame plate, a reducer mounted on the top of the frame plate, and rollers mounted on the bottom right side of the frame plate. A cover is fixed on the bottom left side of the frame plate. A drive motor is mounted on the input end of the reducer, and the drive motor is equipped with a speed control switch. The machine also includes… A polishing mechanism is located inside the cover and rotates with the cover. The polishing mechanism is installed at the output end of the reducer. An additive device is installed on the top of the reducer, and polishing agent is fed into the polishing mechanism through the additive device.

[0008] Preferably, the polishing mechanism includes a mounting plate, a movable plate, and a polishing pad. A hollow shaft is provided on the top of the mounting plate. A bearing and a shaft seal are fitted between the hollow shaft and the cover. The upper end of the hollow shaft passes through the reducer. A first bearing and a first shaft seal are fitted between the hollow shaft and the reducer. The movable plate is elastically mounted below the mounting plate. A first hollow shaft is provided at the upper end of the movable plate. The first hollow shaft is movably mounted inside the hollow shaft. A Velcro fastener is fitted between the polishing pad and the movable plate.

[0009] Preferably, the polishing pad has multiple fan-shaped dispersion grooves. The polishing agent flowing down from the hollow shaft and the first hollow shaft is centrifugally thrown into the dispersion grooves. As the mounting plate rotates, the polishing agent is coated on the floor. The width of the dispersion grooves gradually increases in the direction away from the first hollow shaft. A central hole is provided at the center of the polishing pad. The central hole communicates with the multiple dispersion grooves, and the diameter of the central hole is larger than the inner diameter of the first hollow shaft.

[0010] Preferably, two or more guide shafts are arranged in a ring at the top of the movable plate. The guide shafts pass upward through the mounting plate and are fitted with limit nuts. A spring is sleeved on the guide shaft and acts between the mounting plate and the movable plate.

[0011] Preferably, a shaft cover is threaded to the upper end of the hollow shaft, and a filling hole is provided at the center of the shaft cover. The diameter of the filling hole is smaller than the inner diameter of the hollow shaft, and the adding device is inserted through the filling hole.

[0012] Preferably, the adding device includes a container, a tube at the lower end of the container, a regulating valve for adjusting the output flow of polishing agent installed on the tube, a cap detachably installed at the upper end of the container, a vertically penetrating vent hole at the top of the cap, and a bracket installed between the container and the reducer; the lower end of the tube is inserted into the filling hole, and the tube and the filling hole are fitted with a clearance fit.

[0013] Preferably, the bottom of the hollow shaft is provided with a large-diameter guide hole, the diameter of which is larger than the inner diameter of the hollow shaft. The first hollow shaft is inserted into the guide hole, and a sealing ring is fitted on the outer wall of the first hollow shaft. The sealing ring cooperates with the guide hole to form a seal.

[0014] The beneficial effects of this utility model are: This device allows for the addition of polishing agent via an additive mechanism. As the movable plate rotates, the polishing agent flows in through the hollow shaft and the first hollow shaft, and is then centrifugally ejected into the dispersion tank, where it is applied to the ground. With the rotation of the polishing pad, the polishing agent effectively polishes the ground, eliminating the need for manual application and greatly improving the efficiency of ground polishing. This device has a simple structure, low cost, and is suitable for widespread use. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] See Figure 1 The illustrated high-efficiency terrazzo surface polishing machine includes a frame plate 1, a reducer 2 mounted on the top of the frame plate 1, and rollers 3 mounted on the bottom right side of the frame plate 1. A cover 4 is fixed on the bottom left side of the frame plate 1. A drive motor 5 is mounted on the input end of the reducer 2. The drive motor 5 is equipped with a speed control switch and preferably has over-temperature protection, automatically stopping the machine when the motor temperature is too high. A sealing strip can be embedded at the bottom edge of the cover 4 for bonding between surfaces to form a seal. It also includes... Polishing mechanism 6 is located inside the cover 4 and is rotatably engaged with the cover 4. Polishing mechanism 6 is installed at the output end of the reducer 2. Adding device 7 is installed on the top of the reducer 2, and polishing agent is input into the polishing mechanism 6 through the adding device 7.

[0023] See Figure 2 As shown, the polishing mechanism 6 includes a mounting plate 61, a movable plate 62, and a polishing pad 63. A hollow shaft 64 is provided on the top of the mounting plate 61. A bearing and a shaft seal are fitted between the hollow shaft 64 and the cover 4. The upper end of the hollow shaft 64 passes through the reducer 2. A first bearing and a first shaft seal are fitted between the hollow shaft 64 and the reducer 2. The movable plate 62 is elastically installed below the mounting plate 61. A first hollow shaft 65 is provided on the upper end of the movable plate 62. The first hollow shaft 65 is movably installed inside the hollow shaft 64. A Velcro fastener is fitted between the polishing pad 63 and the movable plate 62.

[0024] In the above technical solution, polishing point 63 is preferably a polyester fiber matrix.

[0025] The reducer 2 is a conventional gear reducer. In this embodiment, its input ratio and output ratio are 4:1, that is, the drive motor 5 rotates 4 revolutions and the hollow shaft 64 rotates 1 revolution.

[0026] In this embodiment, the hollow shaft 64 replaces the output shaft of the reducer 2 terminal. Therefore, the hollow shaft 64 needs to be sealed with a first shaft seal at the point where it passes through the reducer 2. This technique maintains the upper and lower conduction of the hollow shaft 64, facilitating the addition of polishing agent with the addition device 7.

[0027] The polishing pad 63 is detachably fixed with Velcro, and can be removed and replaced after the polishing pad 63 is worn to a certain extent.

[0028] In actual polishing operations, the rotation speed of the movable plate 62 is controlled at 600~1200 rpm.

[0029] See Figure 3 As shown, the polishing pad 63 has multiple fan-shaped dispersion grooves 631. The polishing agent flowing down from the hollow shaft 64 and the first hollow shaft 65 is centrifugally thrown into the dispersion grooves 631. As the mounting plate 61 rotates, the polishing agent is coated on the floor. The width of the dispersion grooves 631 gradually increases in the direction away from the first hollow shaft 65. A central hole 666 is provided at the center of the polishing pad 63. The central hole communicates with the multiple dispersion grooves 631, and the diameter of the central hole is larger than the inner diameter of the first hollow shaft 65.

[0030] By using the dispersion tank 631, the polishing agent can be thrown into the dispersion tank 631 when the movable plate 62 rotates, so that the polishing agent 631 is applied to the ground. The polishing work of the ground is completed during the rotation of the polishing pad 63.

[0031] See Figure 2 As shown, two or more guide shafts 621 are distributed in a ring at the top of the movable plate 62. The guide shafts 621 pass upward through the mounting plate 61 and are fitted with limit nuts 622. A spring 623 is sleeved on the guide shaft 621, and the spring 623 acts between the mounting plate 61 and the movable plate 62.

[0032] In the above technical solution, the elastic force provided by the spring 623 ensures that the polishing pad 63 remains in contact with the ground after it descends, and provides a certain contact force.

[0033] See Figure 1 and Figure 2As shown, a shaft cover 641 is threaded to the upper end of the hollow shaft 64. A filling hole 642 is provided at the center of the shaft cover 641. The diameter of the filling hole 642 is smaller than the inner diameter of the hollow shaft 64. The adding device 7 is inserted through the filling hole 642.

[0034] In the above technical solution, a small-diameter filling hole 642 is used. The lower end of the adding device 7 is inserted through the filling hole 642 and then the polishing agent is output. This can prevent the polishing agent from being thrown out from the upper end of the hollow shaft 64 when the hollow shaft 64 rotates at high speed.

[0035] See Figure 2 and Figure 5 As shown, the adding device 7 includes a container 71, with a tube 72 at the lower end of the container 71. A regulating valve 73 for adjusting the output flow of polishing agent is installed on the tube 72. A tube cap 74 is detachably installed at the upper end of the container 71. A vertically penetrating vent hole is provided at the top of the tube cap 74. A bracket 75 is installed between the container 71 and the reducer 2. The lower end of the tube 72 is inserted into the filling hole 642, and the tube 72 and the filling hole 642 are in clearance fit.

[0036] In the above technical solution, the container 71 is made of a light-transmitting material, which makes it easy to observe the amount of polishing agent at all times.

[0037] By opening the regulating valve 73, the polishing agent flows downward into the hollow shaft 64.

[0038] The opening degree of regulating valve 73 is adjustable.

[0039] The vent allows the container 71 to maintain a constant atmospheric pressure, facilitating the outflow of polishing agent.

[0040] See Figure 4 As shown, the bottom of the hollow shaft 64 is provided with a large-diameter guide hole 644. The diameter of the guide hole 644 is larger than the inner diameter of the hollow shaft 64. The first hollow shaft 65 is inserted into the guide hole 644. A sealing ring 651 is fixed on the outer wall of the first hollow shaft 65. The sealing ring 651 cooperates with the guide hole 644 to form a seal.

[0041] This technical solution allows the hollow shaft and the first hollow shaft to be adapted together, and allows the polishing agent to flow effectively into the first hollow shaft.

[0042] The method of polishing terrazzo floors using this device is as follows: First, close the regulating valve, open the tube cap 74, and then add polishing agent into container 71.

[0043] The second step is to move the device to the polishing area, connect the drive motor 5 to the power supply, and adjust the output speed of the drive motor 5 through the speed control switch, and wait for the speed to stabilize.

[0044] The third step is to open the regulating valve so that the polishing agent is applied to the ground after passing through the hollow shaft and the first hollow shaft. By rotating the movable plate, the polishing pad mixes the polishing agent to polish the ground.

[0045] The fourth step is to maintain a slow pushing speed of 5-10 meters per minute during the polishing process to complete the long-distance polishing.

[0046] It is important to note that polishing pad 3 needs to be replaced promptly according to the degree of wear to maintain effective contact between polishing pad 3 and the ground.

[0047] At the same time, the coaxiality between the insertion tube and the hollow shaft should be increased as much as possible so that the polishing agent does not come into contact with the inner wall of the hollow shaft and the first hollow shaft as it flows downward. The best state is that the polishing agent drips directly from the insertion tube onto the ground, and then is centrifugally scraped into the dispersion tank by the rotation of the polishing pad 3, and then applied to the ground.
