[0077] like Figure 1-7 As shown, a floor back grooving device includes:

[0078] The frame includes a base 11 and side panels 12 arranged parallel to both sides of the base 11;

[0079] The chain plate drive assembly 20 is fixedly mounted on one side of the side plate 12, and the chain plate drive assembly 20 is provided with a drive portion that passes through both side plates 12;

[0080] A pair of chain plate tensioning and adjusting mechanisms 30 are movably mounted on the corresponding side plates 12 , and the chain plate tensioning and adjusting mechanisms 30 are provided with driven wheels 36 on the inner sides of the corresponding side plates 12 ;

[0081] A movable chain plate 40 is movably disposed between the pair of side plates 12 , one end of which is sleeved on the driving portion of the chain plate driving assembly 20 , and the other end of which is sleeved on the driven wheel 36 of the chain plate tensioning and adjusting mechanism 30 ;

[0082] The chain plate driving assembly 20 is adapted to drive the movable chain plate 40 to rotate;

[0083] The upper pressing adjustment mechanism 50 is installed on the side plate 12 on one side, and the upper pressing adjustment mechanism 50 is provided with a lifting drive end;

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

[0085] The upper pressing adjustment mechanism 50 is adapted to drive the upper pressing assembly 60 to move in the vertical direction through the lifting drive end;

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

[0087] The conveying wheel assembly 70 is installed on the upper pressing assembly 60 along the floor conveying channel;

[0088] 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 being hinged to the lifting plate 85 ;

[0090] The mounting plate adjustment mechanism 100 is fixed to the lifting plate 85. The mounting plate adjustment mechanism 100 is provided with an action end, which is connected to the slotted drive source mounting plate 90. 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 the slotted driving source mounting plate 90 ;

[0092] The output spindle 120 is installed 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 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 pressing adjustment mechanism 50 is first adjusted according to the thickness of the floor to be processed. The upper pressing adjustment mechanism 50 moves the upper pressing 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 pressing assembly 60 and the upper surface of the movable chain plate 40, thereby ensuring the stability of the floor during processing.

[0094] Next, to accommodate 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, thereby adjusting the overall height of the slotting drive source 110 and output spindle 120 on the slotting drive source mounting plate 90. Finally, the mounting plate adjustment mechanism 100 is used to adjust the tilt angle of the slotting drive source mounting plate 90 to ensure that the slotting knife can accurately achieve the required slotting depth.

[0095] After adjustment is complete, the chain drive assembly 20 is activated, and the movable chain 40 and conveyor wheel assembly 70 work together to smoothly transport the floorboard to the slotting position. Before the floorboard reaches the designated position, the slotting drive source 110 is activated in advance, driving the slotting cutter on the output spindle 120 to rotate at high speed, slotting the back of the floorboard. Throughout the entire process, the upper clamping assembly 60 and the movable chain 40 work together to ensure stable conveyance of the floorboard and precise and consistent slotting.

[0096] During the assembly stage, the movable chain plate 40 is mounted on the chain plate drive 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 the optimal tension, ensuring the stability of the floor transportation.

[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, such as Figure 1 and Figure 3 As shown, the side panel 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] The tensioning plate 31 is slidably disposed on the side plate 12 and is provided with four adjustment slots corresponding to the long waist slots 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 to 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, such as Figure 1 and Figure 3 As shown, the chain plate tensioning adjustment mechanism 30 further includes:

[0106] The fixing plate 33 is fixedly mounted on the corresponding side plate 12 and has a horizontal connection hole.

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

[0108] An adjusting bolt 35 , which is threadably engaged with the adjusting nut 34 and has one end passing through the connection 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, sliding stoppers are fixed to the side panels 12 on the upper and lower sides of the tensioning plate 31. Horizontally disposed grooves are provided on the upper and lower sides of the tensioning plate 31, and the tensioning plate 31 slides on the sliding stoppers. The chain plate tensioning adjustment mechanism 30 is used to adjust the tension of the movable chain plate 40. The elongated waist grooves on the side panels 12 also provide space for the tensioning plate 31 to move horizontally, allowing for flexible adjustment of the position of the driven wheel 36. The adjustment grooves on the tensioning plate 31 correspond to the elongated waist grooves on the side panels 12. The tensioning plate 31 can be secured in position by fixing members 32, thereby adjusting the tension of the movable chain plate 40.

[0111] The chain tensioning mechanism 30 is adjusted as follows: First, loosen the fixing member 32, allowing the tensioning plate 31 to slide freely on the side plate 12. Then, rotate the adjusting bolt 35 until it abuts the fixing plate 33, thereby driving the adjusting nut 34 and the tensioning plate 31 horizontally. This design allows the operator to precisely control the position of the driven wheel 36, thereby adjusting the tension of the movable chain 40. When the desired tension is achieved, re-tighten the fixing member 32 to secure the tensioning plate 31 in the desired position.

[0112] Specifically, such as Figure 1 and Figure 4 As shown, the upper pressing adjustment mechanism 50 may be structured as follows, including:

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

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

[0115] Nut block 52, the nut block 52 is fixed on the upper pressing assembly 60, and the lifting drive end is set on the nut block 52;

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

[0117] The screw lifting assembly 51 is adapted to drive the screw 53 to rotate, thereby driving the upper pressing 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 precisely control the raising and lowering of the upper clamping assembly 60. Vertical adjustment is achieved through the screw lifting assembly 51. The threaded connection between the drive screw 53 and the nut block 52 converts rotational motion into linear motion, thereby achieving the raising and lowering of the upper clamping assembly 60.

[0119] The upper clamping adjustment mechanism 50 operates as follows: To adjust the height of the upper clamping assembly 60, the screw lift assembly 51 is used to rotate the drive screw 53. Since the nut block 52 is fixed to the upper clamping assembly 60 and threadedly connected to the drive screw 53, the rotation of the drive screw 53 drives the nut block 52 to move vertically, thereby raising and lowering the upper clamping assembly 60 to accommodate floor thicknesses or adjust the clamping force.

[0120] In this embodiment, two screw lift assemblies 51 are used, and the two screw lift assemblies 51 are connected to their first power input ends via a connecting shaft, ensuring synchronous lifting of both sides. This ensures that the upper clamping assembly 60 remains horizontal during the lifting process, avoiding tilting or uneven pressure distribution caused by unilateral lifting.

[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, such as Figure 1 and Figure 7 As shown, the floor back grooving device also includes a manual adjustment input component, 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 is rotatably mounted and extends through both side plates 12 , with one end thereof being drivingly connected to the first power input end of the upper pressing adjustment mechanism 50 , and the other end extending to the outside of the opposite side plate 12 ;

[0127] A second connecting shaft 132 is provided parallel to the first connecting shaft 131 and is rotatably mounted on the side plate 12. The second connecting shaft 132 is provided with a main shaft lifting transmission end extending out of the side plate 12, 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 drive 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 engaged 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 operational efficiency.

[0131] Specifically, such as Figure 1 and Figure 6 As shown, the upper pressing assembly 60 may have the following structure, including:

[0132] A fixed side plate 61 is movably connected to the side plate 12 on one side of the base 11 and is connected to the lifting drive end of the upper pressing 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 upper clamping assembly 60 provides stable pressure and restraint, ensuring precise positioning and processing quality of the floor during the grooving process. The fixed side panel 61 is movably connected to the side panel 12 of the base 11. Specifically, the movably connected side panel 61 can be provided with a vertically mounted column on the side panel 12, through which the fixed side panel 61 is mounted on the side panel 12. The fixed side panel 61 is connected to the lifting drive end of the upper clamping adjustment mechanism 50, allowing the upper clamping assembly 60 to be adjusted vertically to accommodate floors of varying thicknesses. A dust cover 62 is fixed to the fixed side panel 61, which not only provides protection but also effectively controls dust generated during the machining process. In actual operation, the upper clamping assembly 60, controlled by the upper clamping adjustment mechanism 50, can automatically adjust its height according to the thickness of the floor. When the floor enters the machining area, the upper clamping assembly 60 descends to the appropriate position, applying uniform pressure to the floor to ensure that the floor remains stable during the grooving process. At the same time, the dust cover 62 seals the machining area, reducing dust spillage and improving the working environment.

[0135] In addition, a dust suction hole is provided on the dustproof housing 62 at a position corresponding to the output spindle 120 and is 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 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, such as Figure 1 and Figure 6 As shown, the upper pressing assembly 60 further 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, which is transmission-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 conveying start process.

[0140] The conveying wheel group 70 is provided with seven roller groups along the floor conveying channel 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 drive source 63 is connected on the first roller group at the beginning of the floor conveying channel direction, and this arrangement mode is conducive to the uniform transmission of power. When the first roller group is driven, the friction 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, such as Figure 1 and Figure 6 As shown, the upper pressing assembly 60 further includes:

[0144] A brush mounting shaft 64 is hinged to the fixed side plate 61 and is suitable for mounting a brush;

[0145] The second driving source 65 is installed on the fixed side plate 61 , and the second driving source 65 is in transmission connection with the brush mounting shaft 64 .

[0146] In this embodiment, if Figure 1 and Figure 6 As shown, brushes are installed on the brush mounting 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 drive source 65 is mounted on the fixed side plate 61 and is in transmission connection with the brush mounting shaft 64. This configuration allows the brush to move independently of the conveying system. By controlling the second drive source 65, the rotation speed and direction of the brush can be adjusted.

[0148] The brush mounting shaft 64 is positioned behind the output spindle 120 in the direction of the floor conveyor channel, specifically between the penultimate and second roller groups. This position ensures that the brush can clean the floor after grooving is complete, effectively removing debris and dust generated during the process. Furthermore, its location at the end of the conveyor system allows the brush to more fully contact and clean the floor surface. Both the roller drive source 63 and the second drive source 65 can be a combination of a motor and a reducer.

[0149] Specifically, such as Figure 1 and Figure 5 As shown, the slot drive source lifting transmission member can 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, which slide in conjunction with corresponding guide rails 81;

[0152] The worm gear mechanism 83 is fixed to 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 84.

[0154] In this embodiment, if Figure 1 and Figure 5 As shown, the slotting drive source lifting transmission member functions to control the lifting of the slotting drive source 110 and ensure smooth vertical movement of the lifting plate 85. The worm gear mechanism 83 converts rotational motion into linear motion of the lifting screw 84 through the meshing of the worm and worm. The worm gear has advantages such as good self-locking performance, a large transmission ratio, and smooth movement. The lifting plate 85 is threadedly connected to the lifting screw 84 and moves up and down as the lifting screw 84 rotates, thereby driving the slotting drive source 110 mounted thereon for height adjustment.

[0155] In actual use, the operator can precisely adjust the height of the slotting drive source 110 by rotating the input end of the worm gear mechanism 83, for example manually. Fine adjustments can also be made based on the desired slotting depth. Furthermore, the self-locking nature of the worm gear mechanism 83 reliably maintains the position of the slotting drive source 110 even when the machine is stopped.

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

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

[0158] An adjustment driving source 102 is mounted on the extension fixing plate 101;

[0159] The transmission connecting plate 103 has one end eccentrically hinged to the output shaft of the adjustment drive source 102 and the other end hinged to the slotted drive 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 adjustment drive source 102 is a combination of a motor and a reducer.

[0161] When the output shaft of the adjustment drive source 102 rotates, it causes one end of the transmission connecting plate 103 to undergo eccentric motion. Because the other end of the transmission connecting plate 103 is hingedly connected to the slotting drive source mounting plate 90, this eccentric motion translates into rotational motion of the slotting drive source mounting plate 90 about its hinge point on the lifting plate 85. By controlling the movement of the adjustment drive source 102, the tilt angle of the slotting drive source mounting plate 90 can be precisely adjusted, thereby varying the cutting depth of the slotting blade 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 scope of protection of the present invention.
