[0083] An upper clamping adjustment mechanism 50, which is mounted on the side plate 12 on one side and is provided with a lifting drive end;

[0084] An upper clamping assembly 60, which is movably disposed on the side plate 12 and is located above the movable chain plate 40, and is connected to the lifting drive end of the upper clamping adjustment mechanism 50;

[0085] The upper clamping adjustment mechanism 50 is suitable for driving the upper clamping assembly 60 to move in the vertical direction through the lifting drive end;

[0086] The lower surface of the upper clamping assembly 60 is arranged parallel to and spaced from the upper surface of the movable chain plate 40, forming a floor conveying channel therebetween;

[0087] A conveying wheel assembly 70, the conveying wheel assembly 70 is installed on the upper clamping assembly 60 along the floor conveying channel;

[0088] A slotted driving source lifting transmission member, the slotted driving source lifting transmission member is mounted on the base 11, and a lifting plate 85 is provided on the slotted driving source lifting transmission member;

[0089] A slotted drive source mounting plate 90, the slotted drive source mounting plate 90 is hinged on the lifting plate 85;

[0090] The mounting plate adjustment mechanism 100 is fixed on the lifting plate 85, and an action end is provided on the mounting plate adjustment mechanism 100, and the action end is connected to the slotted drive source mounting plate 90, and the mounting plate adjustment mechanism 100 is suitable for driving the slotted drive source mounting plate 90 to rotate around the hinge point on the lifting plate 85;

[0091] A slotted driving source 110, the slotted driving source 110 is mounted on a slotted driving source mounting plate 90;

[0092] The output spindle 120 is mounted on the slotting drive source mounting plate 90. The output spindle 120 is provided with a transmission end and a connecting end. The transmission end is transmission-connected to the slotting drive source 110. The connecting end of the output spindle 120 passes through the slotting drive source mounting plate 90 and extends into the upper clamping assembly 60. The connecting end is suitable for installing a slotting knife.

[0093] In this embodiment, if Figure 1As shown, during use, the upper clamping adjustment mechanism 50 is first adjusted according to the thickness of the floor to be processed. The upper clamping adjustment mechanism 50 is used to move the upper clamping assembly 60 in the vertical direction until a floor conveying channel suitable for the thickness of the floor to be processed is formed between the lower surface of the upper clamping assembly 60 and the upper surface of the movable chain plate 40, thereby ensuring the stability of the floor during processing.

[0094] Next, in order to adapt to different slot positions and depth requirements, the slotting drive source lifting transmission member is used to control the up and down movement of the lifting plate 85 to achieve the overall height adjustment of the slotting drive source 110 and the output spindle 120 on the slotting drive source mounting plate 90. Finally, the mounting plate adjustment mechanism 100 is used to adjust the inclination angle of the slotting drive source mounting plate 90 to ensure that the slotting knife can accurately reach the required slotting depth.

[0095] After the adjustment is completed, the chain plate driving assembly 20 is started, and the movable chain plate 40 and the conveying wheel assembly 70 work together to smoothly convey the floor to the slotting position. Before the floor reaches the specified position, the slotting driving source 110 is turned on in advance to drive the slotting knife on the output spindle 120 to rotate at high speed to perform slotting operations on the back of the floor. During the entire processing process, the upper clamping assembly 60 and the movable chain plate 40 jointly ensure the stable conveying of the floor and ensure the accuracy and consistency of the slotting.

[0096] During the assembly stage, the movable chain plate 40 is mounted on the chain plate driving assembly 20 and the chain plate tensioning adjustment mechanism 30. By adjusting the chain plate tensioning adjustment mechanism 30, it can be ensured that the movable chain plate 40 is maintained at an optimal tension, thereby ensuring the stability of the floor conveying.

[0097] In this embodiment, the slotting drive source 110 may be a motor, the transmission connection between the slotting drive source 110 and the output spindle 120 may be a belt drive, and the chain plate drive assembly 20 may be a combination of a motor and a reducer.

[0098] Specifically, Figure 1 and Figure 3 As shown, the side plate 12 is provided with a long strip waist groove extending in the horizontal direction;

[0099] The chain plate tensioning adjustment mechanism 30 may have the following structure, including:

[0100] A tensioning plate 31, the tensioning plate 31 is slidably disposed on the side plate 12, and the tensioning plate 31 is provided with four adjustment grooves corresponding to the long waist grooves of the side plate 12;

[0101] The driven wheel 36 is hinged to the corresponding tensioning plate 31;

[0102] The side plate 12 of the base 11 is provided with four fixing holes;

[0103] Four fixing members 32 are adapted to pass through the adjustment slots and be threadedly connected with corresponding fixing holes to fix the tensioning plate 31 at a predetermined position.

[0104] In this embodiment, if Figure 1 and Figure 3 As shown, the number of adjustment slots, fixing holes and fixing members 32 corresponds one to one. In some embodiments, the number of adjustment slots, fixing holes and fixing members 32 is not limited to four and can be set according to specific needs.

[0105] Specifically, Figure 1 and Figure 3 As shown, the chain plate tensioning adjustment mechanism 30 also includes:

[0106] A fixing plate 33, the fixing plate 33 is fixedly mounted on the corresponding side plate 12, and a horizontally arranged connection hole is provided on the fixing plate 33;

[0107] An adjusting nut 34, wherein the adjusting nut 34 is fixed on the tensioning plate 31;

[0108] An adjusting bolt 35, wherein the adjusting bolt 35 is threadably matched with the adjusting nut 34, and one end of the adjusting bolt 35 passes through a connecting hole of the fixing plate 33;

[0109] The adjusting bolt 35 is adapted to abut against the fixing plate 33 through rotation adjustment, thereby driving the adjusting nut 34 and the tensioning plate 31 fixedly connected thereto to move in the horizontal direction.

[0110] In this embodiment, if Figure 1 and Figure 3 As shown, on the upper and lower sides of the tensioning plate 31, there are also sliding limit plates fixed on the side plate 12, and the upper and lower sides of the tensioning plate 31 are provided with horizontally arranged grooves, and the tensioning plate 31 is slidably arranged on the sliding limit plates. The function of the chain plate tensioning adjustment mechanism 30 is to adjust the tension of the active chain plate 40. The long strip waist groove on the side plate 12 also provides a space for the tensioning plate 31 to move horizontally, so that the position of the driven wheel 36 can be flexibly adjusted. The adjustment groove on the tensioning plate 31 corresponds to the long strip waist groove of the side plate 12, and the tensioning plate 31 can be fixed in a suitable position by the fixing member 32, so as to adjust the tension of the active chain plate 40.

[0111] The adjustment process of the chain plate tension adjustment mechanism 30 is as follows: first, loosen the fixing member 32 so that the tension plate 31 can slide freely on the side plate 12. Then, by rotating the adjustment bolt 35 so that it abuts against the fixing plate 33, the adjustment nut 34 and the tension plate 31 are driven to move in the horizontal direction. This design allows the operator to accurately control the position of the driven wheel 36, thereby adjusting the tension of the movable chain plate 40. When the desired tension is reached, re-tighten the fixing member 32 to fix the tension plate 31 at a predetermined position.

[0112] Specifically, Figure 1 and Figure 4 As shown, the upper pressing adjustment mechanism 50 may be of the following structure, including:

[0113] Two screw lifting assemblies 51, the screw lifting assemblies 51 are mounted on the side plate 12 on one side;

[0114] A driving screw rod 53, wherein the driving screw rod 53 is vertically arranged on the screw rod lifting assembly 51;

[0115] A nut block 52, the nut block 52 is fixed on the upper clamping assembly 60, and the lifting drive end is arranged on the nut block 52;

[0116] The driving screw rod 53 passes through the nut block and is threadedly connected thereto;

[0117] The screw lifting assembly 51 is suitable for driving the screw 53 to rotate, thereby driving the upper clamping assembly 60 to move in the vertical direction.

[0118] In this embodiment, if Figure 1 and Figure 4 As shown, the upper clamping adjustment mechanism 50 is used to achieve precise lifting and lowering control of the upper clamping assembly 60. The vertical adjustment is achieved through the screw lifting assembly 51. The threaded connection between the driving screw 53 and the nut block 52 converts the rotational motion into linear motion, thereby achieving the lifting and lowering of the upper clamping assembly 60.

[0119] The working process of the upper clamping adjustment mechanism 50 is as follows: when the height of the upper clamping assembly 60 needs to be adjusted, the screw lifting assembly 51 is used to drive the driving screw 53 to rotate. Since the nut block 52 is fixed on the upper clamping assembly 60 and is threadedly connected to the driving screw 53, the rotation of the driving screw 53 will drive the nut block 52 to move in the vertical direction, thereby realizing the lifting and lowering of the upper clamping assembly 60 to adapt to floors of different thicknesses or adjust the clamping force.

[0120] In this embodiment, two screw lifting assemblies 51 are used, and the two screw lifting assemblies 51 are connected to the first power input end via a connecting shaft, thereby ensuring the synchronization of lifting on both sides, ensuring that the upper clamping assembly 60 remains horizontal during the lifting process, and avoiding tilting or uneven pressure distribution caused by lifting on one side.

[0121] In some embodiments, the number of screw lifting assemblies 51 is not limited to two and can be set according to specific needs.

[0122] Specifically, Figure 1 and Figure 7 As shown, the floor back grooving device also includes a manually adjustable input assembly, wherein:

[0123] The upper pressing adjustment mechanism 50 is provided with a first power input end;

[0124] The slotting drive source lifting transmission member is provided with a second power input end;

[0125] The manual adjustment input component may have the following structure, including:

[0126] A first connecting shaft 131, which is rotatably mounted and extends through the two side plates 12, one end of which is drivingly connected to the first power input end of the upper clamping adjustment mechanism 50, and the other end of which extends to the outside of the opposite side plate 12;

[0127] A second connecting shaft 132, which is arranged parallel to the first connecting shaft 131 and rotatably mounted on the side plate 12, and a main shaft lifting transmission end extending out of the side plate 12 is provided on the second connecting shaft 132, and a second sprocket is provided on the main shaft lifting transmission end;

[0128] The main shaft lifting transmission shaft 133 is rotatably mounted on the base 11, one end of which is drivingly connected to the second power input end of the slotted driving source lifting transmission member, and the other end extends to the outside of the opposite side plate 12 and is provided with a first sprocket;

[0129] The transmission chain 134 is meshed with the first sprocket on the main shaft lifting transmission shaft 133 and the second sprocket on the second connecting shaft 132 for transmission.

[0130] In this embodiment, if Figure 1 and Figure 7 As shown, the function of the manual adjustment input assembly is to provide a more convenient way to adjust the height of the upper clamping assembly 60 and the slotting drive source 110. The working principle of the manual adjustment input assembly is as follows: when the operator needs to adjust the height of the upper clamping assembly 60, it can be achieved by rotating the first connecting shaft 131. The first connecting shaft 131 is connected to the first power input end of the upper clamping adjustment mechanism 50 through a bevel gear set. At the same time, when the height of the slotting drive source 110 needs to be adjusted, the operator can rotate the second connecting shaft 132. The second connecting shaft 132 transmits the rotational motion to the second power input end of the slotting drive source lifting transmission member through the second sprocket on the main shaft lifting transmission end, the transmission chain 134 and the first sprocket on the main shaft lifting transmission shaft 133. The parallel arrangement of the first connecting shaft 131 and the second connecting shaft 132 allows the operator to complete two adjustments at the same position, thereby improving the operating efficiency.

[0131] Specifically, Figure 1 and Figure 6 As shown, the upper clamping assembly 60 may be of the following structure, including:

[0132] A fixed side plate 61, the fixed side plate 61 is movably connected to the side plate 12 on one side of the base 11, and the fixed side plate 61 is connected to the lifting drive end of the upper clamping adjustment mechanism 50;

[0133] The dustproof shell 62 is fixed on the fixed side plate 61 .

[0134] In this embodiment, if Figure 1 and Figure 6 As shown, the function of the upper clamping assembly 60 is to provide stable pressure and restriction to ensure the precise positioning and processing quality of the floor during the slotting process. The fixed side plate 61 is movably connected to the side plate 12 of the base 11. The movably connected method can be that a vertically arranged column is provided on the side plate 12, and the fixed side plate 61 is arranged on the side plate 12 through the column. The fixed side plate 61 is connected to the lifting drive end of the upper clamping adjustment mechanism 50, so that the upper clamping assembly 60 can be adjusted in the vertical direction to adapt to floors of different thicknesses. The dustproof shell 62 is fixed on the fixed side plate 61, which not only plays a protective role, but also effectively controls the dust generated during the processing. In actual operation, the upper clamping assembly 60 can automatically adjust the height according to the thickness of the floor through the control of the upper clamping adjustment mechanism 50. When the floor enters the processing area, the upper clamping assembly 60 drops to an appropriate position, applies uniform pressure to the floor, and ensures that the floor remains stable during the slotting process. At the same time, the dustproof shell 62 closes the processing area, reduces dust spillage, and improves the working environment.

[0135] In addition, a dust suction hole is provided on the dustproof shell 62 at a position corresponding to the output spindle 120 and connected to a negative pressure air source. During the slotting process, the negative pressure air source continuously absorbs dust and debris generated by the processing through the dust suction hole.

[0136] A floor scraper is also provided at a reserved position corresponding to the output spindle 120 in the dustproof shell 62 , and the floor scraper is fixed to the dustproof shell 62 by bolts.

[0137] Specifically, Figure 1 and Figure 6 As shown, the upper clamping assembly 60 also includes:

[0138] A roller group driving source 63 is installed on the fixed side plate 61 . The roller group driving source 63 is provided with a driving end, and the driving end is drivingly connected to one of the roller groups of the conveying wheel group 70 .

[0139] In this embodiment, if Figure 1 and Figure 6 As shown, the roller group driving source 63 is connected to a roller group in the conveying wheel group 70 through its driving end, ensuring that the floor can move smoothly and continuously during the initial conveying process.

[0140] The conveying wheel group 70 is provided with seven roller groups along the floor conveying passage direction, and each roller group is provided with two rollers. The rollers are rotatably connected to the same rotating shaft, and the rotating shaft is hinged on the fixed side plate 61.

[0141] The roller group driving source 63 is connected on the first roller group at the beginning of the floor conveying passage direction, and this arrangement mode is conducive to the uniform transmission of power. When the first roller group is driven, the friction force between the floor and other roller groups can drive the whole conveying wheel group 70 to work in coordination.

[0142] In some embodiments, the number of roller group driving sources 63 is not limited to one and can be set according to specific needs.

[0143] Specifically, Figure 1 and Figure 6 As shown, the upper clamping assembly 60 also includes:

[0144] A brush installation shaft 64, the brush installation shaft 64 is hinged on the fixed side plate 61, and the brush installation shaft 64 is suitable for installing a brush;

[0145] The second driving source 65 is installed on the fixed side plate 61 , and the second driving source 65 is drivingly connected to the brush installation shaft 64 .

[0146] In this embodiment, if Figure 1 and Figure 6 As shown, brushes are installed on the brush installation shaft 64. These brushes play a role in cleaning and polishing during the floor processing process, which helps to improve the processing quality.

[0147] The second driving source 65 is mounted on the fixed side plate 61 and is in driving connection with the brush mounting shaft 64. This configuration enables the brush to move independently of the conveying system. By controlling the second driving source 65, the rotation speed and direction of the brush can be adjusted.

[0148] The brush installation shaft 64 is located behind the output spindle 120 in the direction of the floor conveying channel, specifically between the last roller group and the second roller group. This position ensures that the brush can be cleaned after the floor is grooved, and can effectively remove the debris and dust generated during the processing. Secondly, because it is located at the end of the conveying system, it is conducive to the brush to more fully contact and clean the floor surface. The roller group drive source 63 and the second drive source 65 can specifically be a combination of a motor and a reducer.

[0149] Specifically, Figure 1 and Figure 5 As shown, the slotted driving source lifting transmission member may have the following structure, including:

[0150] Two guide rails 81, the guide rail 81 is fixedly mounted on the side plate 12 on one side of the base 11 along the vertical direction;

[0151] Four sliders 82, the sliders 82 are slidably matched with corresponding guide rails 81;

[0152] A worm gear mechanism 83, which is fixed on the base 11 and includes a worm gear, a worm gear, and a lifting screw 84 coaxially connected to the worm gear;

[0153] The lifting plate 85 is fixedly connected to the slider 82 and is threadedly connected to the lifting screw rod 84 .

[0154] In this embodiment, if Figure 1 and Figure 5 As shown, the function of the slotting driving source lifting transmission member is to realize the lifting control of the slotting driving source 110, ensure that the lifting plate 85 moves smoothly in the vertical direction, and the worm gear mechanism 83 converts the rotational motion into the linear motion of the lifting screw 84 through the meshing transmission of the worm gear and the worm gear. The worm gear has the advantages of good self-locking performance, large transmission ratio, and smooth movement. The lifting plate 85 is threadedly connected with the lifting screw 84, and moves up and down with the rotation of the lifting screw 84, thereby driving the slotting driving source 110 installed thereon to adjust the height.

[0155] In actual use, the operator can precisely adjust the height position of the slotting drive source 110 by rotating the input end of the worm gear mechanism 83, such as manually. It can also be fine-tuned according to the slotting depth requirements. In addition, due to the self-locking characteristics of the worm gear mechanism 83, the position of the slotting drive source 110 can be reliably maintained even in the shutdown state.

[0156] Specifically, Figure 1-2 As shown, the mounting plate adjustment mechanism 100 includes:

[0157] An extension fixing plate 101, the extension fixing plate 101 is fixedly disposed on the lifting plate 85;

[0158] An adjusting driving source 102 is installed on the extending fixing plate 101;

[0159] The transmission connecting plate 103 has one end eccentrically hinged on the output shaft of the adjustment driving source 102 and the other end hinged on the slotted driving source mounting plate 90 .

[0160] In this embodiment, if Figure 1-2 As shown, the function of the mounting plate adjustment mechanism 100 is to achieve precise angle adjustment of the slotting drive source mounting plate 90, thereby controlling the depth of the slotting knife. The adjusting drive source 102 is a combination of a motor and a reducer.

[0161] When the output shaft of the adjusting driving source 102 rotates, it drives one end of the transmission connecting plate 103 to perform eccentric movement. Since the other end of the transmission connecting plate 103 is hinged to the slotting driving source mounting plate 90, this eccentric movement is converted into a rotational movement of the slotting driving source mounting plate 90 around its hinge point on the lifting plate 85. By controlling the movement of the adjusting driving source 102, the inclination angle of the slotting driving source mounting plate 90 can be accurately adjusted, thereby changing the cutting depth of the slotting knife relative to the floor.

[0162] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
