[0002] A floor polishing machine, also known as a floor grinding machine or a polishing machine, is a type of mechanical equipment specifically designed for floor treatment.

[0003] The prior art discloses a floor polishing machine (CN220994041U), which includes a rotary polishing device for elastically pressing and rotating to polish the floor, a walking device for supporting movement, and a spraying device for spraying polishing agent. The rotary polishing device is installed at one end of the walking device, and the spraying device is installed on the walking device. The walking device includes a base plate, four walking motors are evenly installed at the four corners of the bottom of the base plate, and walking wheels are installed on the outside of the walking motors. A control console is installed on the base plate, and a battery is installed inside the control console. The spraying device includes a liquid storage tank, and a seat is installed on the top of the liquid storage tank.

[0004] Research revealed that existing polishing technologies require pre-setting to adjust the polishing pressure, which cannot be adjusted in real time according to the flatness of the ground. This results in excessive or insufficient pressure in certain areas, affecting the overall polishing quality. Furthermore, the polishing pressure is not linked to the equipment's movement. When the pressure angle is changed during polishing, the movement cannot adapt to the flatness of the ground, causing the device to tilt and thus affecting the polishing effect.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An adaptive grinding pressure controlled floor polishing machine, comprising:

[0008] The base plate has a control console, a water tank, and a spray pipe installed on its top surface. The spray pipe is connected to the water tank. The bottom of the base plate has symmetrically installed traveling rollers. The interior of the base plate is equipped with a polishing component.

[0009] A polishing assembly includes a lifting frame, a swing lever, an electric grinding disc, a mounting frame, an adapting support block, and gears. The lifting frame is sleeved on a traveling roller. The two ends of the swing lever are movably connected to the lifting frame and the adapting support block, respectively. The electric grinding disc is installed inside the mounting frame, which is hinged to the bottom of the adapting support block. Two adapting support blocks are symmetrically arranged. The gear transmission is located between the two adapting support blocks. The control console is electrically connected to the electric grinding disc.

[0010] In a preferred embodiment of this utility model, a storage groove is provided at the center of the bottom surface of the base plate, the mounting frame is correspondingly snapped into the storage groove, an adaptation cavity is provided in the storage groove, an electric push rod is fixedly provided at the center of the top surface of the base plate, the control console is electrically connected to the electric push rod, and the output end of the electric push rod passes through the adaptation cavity and is connected to a fixed base.

[0011] In a preferred embodiment of this utility model, the bottom of the fixed base is rotatably connected to a gear, and the two adapting blocks are slidably disposed in the adapting cavity. The adapting blocks have an L-shaped structure, and the two adapting blocks mesh with the same gear.

[0012] In a preferred embodiment of this utility model, a nail-shaped limiting rod is installed on the top of the adapting support block. The limiting rod slides through the adapting cavity. A spring is fixed between the limiting rod and the adapting cavity. The limiting rod is elastically connected to the adapting cavity through the spring.

[0013] In a preferred embodiment of the present invention, a hinge seat is fixedly provided on the bottom surface of the adapting support block, and the mounting frame is hinged to an adapting support block at each of the two ends of the top surface through the hinge seats.

[0014] In a preferred embodiment of this utility model, the bottom of the base plate has two lifting cavities, which are symmetrically arranged with the storage groove as the center. The lifting frame slides through the lifting cavities. The base plate has two symmetrical swing cavities, and the adaptation cavity communicates with the lifting cavities on both sides through the swing cavities on both sides.

[0015] In a preferred embodiment of this utility model, the swing lever is rotatably disposed in the swing cavity, and the swing lever is slidably engaged with the lifting frame and the adaptive support block at both ends.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. By setting up polishing components, gear-linked double-sided adaptive blocks and spring elastic buffers, real-time pressure compensation of the electric grinding disc for floor protrusions or depressions is achieved: when the floor protrudes, the corresponding side adaptive block compresses the spring and moves upward, driving the other side adaptive block to move downward and apply pressure through the gear, avoiding local pressure overload; when it is depressed, the opposite is true, ensuring stable grinding pressure per unit area, thereby ensuring good polishing quality.

[0018] 2. The swing lever converts the height change of the polishing components into the lifting and lowering action of the traveling rollers: the position of the ground protrusion determines the adjustment position of the electric grinding disc on one side. The corresponding adjustment position of the adaptation block pushes the lifting frame up and down through the swing lever, so that the traveling rollers on the corresponding side adapt to the terrain changes, thereby maintaining the overall level of the equipment. This solves the problem of device tilting caused by pressure tilt angle changes in the existing technology, thereby linking the polishing components to polish the ground smoothly and ensuring good polishing effect.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] An adaptive grinding pressure controlled floor polishing machine, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, including

[0029] The base plate 10 has a control console 11, a water tank 12, and a spray pipe 13 mounted on its top surface. The spray pipe 13 is connected to the water tank 12. The bottom of the base plate 10 is symmetrically equipped with traveling rollers 15. The interior of the base plate 10 is equipped with a polishing assembly. One end of the top surface of the base plate 10 is equipped with a pusher for moving the device. The water tank 12 is connected to a hose through a diaphragm pump. The water tank 12 is connected to the spray pipe 13 through the hose. The bottom of the spray pipe 13 is arrayed with multiple nozzles.

[0030] The polishing assembly includes a lifting frame 17, a swing lever 18, an electric grinding disc 19, a mounting frame 20, an adaptation block 21, and a gear 25. The lifting frame 17 is sleeved on the traveling roller 15. The two ends of the swing lever 18 are movably connected to the lifting frame 17 and the adaptation block 21, respectively. The electric grinding disc 19 is installed inside the mounting frame 20, which is hinged to the bottom of the adaptation block 21. There are two symmetrically arranged adaptation blocks 21. The gear 25 is driven between the two adaptation blocks 21. The control console 11 is electrically connected to the electric grinding disc 19.

[0031] Specifically, the base plate 10 is the main frame of the equipment. A T-shaped pusher is welded to one end of the top surface of the base plate 10 to facilitate the operator to push the equipment. The interior is provided with a storage slot 30, an adaptation cavity 28, a lifting cavity 29 and a swing cavity 27, forming a space for the installation and movement of the polishing components. The water tank 12 delivers polishing liquid or cleaning liquid to the spray pipe 13 through a diaphragm pump via a hose. Multiple fan-shaped nozzles are arranged in an array at the bottom of the spray pipe 13 to cover the working area of ​​the electric grinding disc 19, thereby achieving cooling and dust reduction in wet polishing.

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, a storage groove 30 is provided at the center of the bottom surface of the base plate 10, and the mounting frame 20 is correspondingly snapped into the storage groove 30. An adaptation cavity 28 is provided in the storage groove 30. An electric push rod 16 is fixedly provided at the center of the top surface of the base plate 10. The control console 11 is electrically connected to the electric push rod 16. The output end of the electric push rod 16 passes through the adaptation cavity 28 and is connected to the fixing seat 22. The adaptation cavity 28 is a mountain-shaped groove composed of a square groove, two trapezoidal grooves and two cylindrical grooves.

[0033] like Figure 3 As shown, a hinge seat 26 is fixedly provided on the bottom surface of the adapting support block 21. The mounting frame 20 is hinged to an adapting support block 21 at both ends of the top surface through the hinge seats 26. The top surface of the mounting frame 20 is symmetrically provided with two U-shaped protrusions, and the U-shaped protrusions are hinged to the hinge seats 26 through pins.

[0034] like Figure 3 and Figure 4As shown, the bottom of the fixed base 22 is rotatably connected to the gear 25, and the two adapting blocks 21 are slidably disposed in the adapting cavity 28. The adapting blocks 21 have an L-shaped structure, and the two adapting blocks 21 mesh with the same gear 25. The adapting block 21 is composed of a rack, a square block and a trapezoidal block. The square block and the rack slide up and down in the square groove, and the trapezoidal block is engaged in the trapezoidal groove.

[0035] like Figure 3 , Figure 4 and Figure 5 As shown, a nail-shaped limiting rod 23 is installed on the top of the adapting support block 21. The limiting rod 23 slides through the adapting cavity 28. A spring 24 is fixed between the limiting rod 23 and the adapting cavity 28. The limiting rod 23 is elastically connected to the adapting cavity 28 through the spring 24. The limiting rod 23 passes through the cylindrical groove. The spring 24 is sleeved on the limiting rod 23. The limiting rod 23 slides elastically in the cylindrical groove through the spring 24.

[0036] The working principle is as follows: the adapting cavity 28 is designed as a mountain-shaped groove, consisting of a central square groove, two trapezoidal grooves on both sides, and two cylindrical grooves on the top. A fixed seat 22, rack, and gear 25 are installed inside the square groove. The trapezoidal grooves constrain the sliding trajectory of the adapting support block 21 through trapezoidal blocks. A limiting rod 23 and a spring 24 are built into the cylindrical grooves. The adapting support block 21 has an L-shaped composite structure, with its bottom hinged to the mounting frame 20 via a hinge seat 26. The top rack meshes with the gear 25. The electric actuator 16 is vertically fixed to the center of the top surface of the base plate 10, and its output end passes through the adapting cavity 28 and connects to the fixed seat 22. Next, the polishing assembly is raised and lowered as a whole via the control console 11 to adapt to different floor heights or storage needs. The trapezoidal block of the adapting support block 21 is engaged in the trapezoidal groove of the adapting cavity 28. The limiting rod 23 passes through the cylindrical groove and is assembled with the spring 24. The spring 24 provides basic elastic pressure and buffers impact, forming a double-sided symmetrical pressure compensation structure. When the electric grinding disc 19 contacts an uneven floor, the two sides of the adapting support block 21 achieve reverse linkage through the gear 25, so that when one side is raised, the other side is pressed down. With the elastic tension of the spring 24, the grinding pressure difference is automatically compensated.

[0037] like Figure 2 and Figure 4 As shown, the bottom of the base plate 10 has two lifting cavities 29, which are symmetrically arranged with the storage groove 30 as the center. The lifting frame 17 slides through the lifting cavity 29. The bottom plate 10 has two swing cavities 27 symmetrically arranged inside. The adaptation cavity 28 communicates with the lifting cavity 29 on both sides through the swing cavity 27 on both sides. The traveling roller 15 consists of two rollers and a shaft. The bottom of the lifting frame 17 has a round hole, which is correspondingly sleeved with the shaft.

[0038] like Figure 2 and Figure 4As shown, the swing lever 18 is rotatably disposed in the swing cavity 27. The swing lever 18 is slidably engaged with the lifting frame 17 and the adapting support block 21 at both ends. The lifting frame 17 is provided with a U-shaped block on the side near the swing cavity 27. The U-shaped block and the trapezoidal block are both provided with a cylinder at the end near the adapting cavity 28. The adapting cavity 28 is provided with a sliding groove at both ends, and the cylinder slides in the sliding groove. The swing lever 18 is provided with a bearing hole at the center. The swing cavity 27 is fixedly provided with a rotating shaft, and the bearing hole is rotatably connected to the rotating shaft.

[0039] The working method is as follows: the bottom round hole of the lifting frame 17 is connected to the shaft of the traveling roller 15, and the top is slidably connected to one end of the swing lever 18 through the cylindrical slider; the middle part of the swing lever 18 is hinged to the swing cavity 27 through the rotating shaft, and the other end cooperates with the trapezoidal block cylindrical slider of the adapting support block 21. When the ground protrudes and causes the electric grinding disc 19 to rise, the corresponding side adapting support block 21 pushes the connected swing lever 18 to swing by sliding the connected cylinder, which drives the lifting frame 17 to move up and down along the lifting cavity 29, thereby driving the adjacent side traveling roller 15 to fall, adjusting the height of the traveling roller 15 to avoid the protruding position, so that the machine body always remains horizontal and avoids the device tilting due to the shift of the center of gravity.
