Description

Technical Field

[0001] The invention relates to the technical field of wood floor processing equipment, and in particular to equipment for processing transverse saw grains on the surface of a wood floor. Background Art

[0002] At present, the wood flooring market offers a wide variety of patterns and colors, and different consumers have different requirements for flooring. Therefore, floor processing companies have developed and produced floors with smooth surfaces, floors with uneven surfaces and concave and convex patterns, brushed non-slip floors, and various antique floors. For example, floors with horizontal saw patterns on the surface imitate the sawtooth marks left on the wood section surface by the saw blades pulling back and forth due to the simplicity of tools hundreds of years ago. However, with the development of modern industrial technology, wood is sawed with high-speed band saws or circular saws, and the wood section surface will no longer have obvious sawtooth marks left by the saw blades pulling back and forth, so it is necessary to use other equipment to process sawtooth marks on the wood floor.

[0003] For example: A Chinese utility model patent with authorization announcement number CN201357469Y discloses a device for making transverse saw patterns on wooden floors. The device uses an ordinary band saw blade to process the surface texture of the wooden floor. By changing the sawtooth shape of the band saw blade, the angle between the band saw blade and the wooden floor, the relative movement speed of the band saw blade and the wooden floor, and the depth of the band saw blade cutting the wooden floor, transverse saw patterns that can express a nostalgic style are processed. However, during the processing process, since the band saw blade cuts into the wooden floor to a certain depth, when the wooden floor is conveyed forward, the band saw blade will leave longitudinal scratches on the wooden floor, affecting the processing effect of the wooden floor grain.

DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0018] Example: Figure 1-7 As shown, a device for processing horizontal saw grains on the surface of a wooden floor comprises a workbench 1, a backing plate 2 arranged on the workbench 1, and a band saw blade 5 arranged in front of the backing plate 2. Transmission rollers 3 are arranged at the front and rear ends of the backing plate 2, and two transmission rollers 3 are distributed at each end. The two transmission rollers 3 are clamped at the front and rear sides of the wooden floor to prevent the wooden floor from moving forward and backward in a direction perpendicular to the backing plate 2 during processing. The backing plate 2 is movably installed on the workbench 1 to adapt to the processing of wooden floors of different thicknesses.

[0019] The band saw blade 5 vertically passes through the workbench 1 , and the band saw blade 5 is connected to a feeding mechanism 7 , which drives the band saw blade 5 to move forward and backward in a direction perpendicular to the backing plate 2 .

[0020] The workbench 1 is provided with a sliding groove 101 perpendicular to the backing plate 2, a band saw mounting seat 9 is provided in the sliding groove 101, a band saw blade 5 is mounted on the band saw mounting seat 9, and a feeding mechanism 7 is connected between the workbench 1 and the band saw mounting seat 9. The band saw blade 5 is an electric reciprocating saw, which can reciprocate in the vertical direction.

[0021] A feeding mechanism 4 is provided on the backing plate 2, and the feeding mechanism 4 pushes the wooden floor forward a set distance at set time intervals.

[0022] like Figure 4 As shown, the feeding mechanism 4 includes a first slider 406, which is slidably installed on the back of the backing plate 2, and the first slider 406 is connected to a first reciprocating mechanism 407. The backing plate 2 is provided with a mounting groove 201 that runs through the front and back, and a friction roller 401 for contacting the back of the wooden floor is provided in the mounting groove 201, and a ratchet mechanism is provided at the end of the friction roller 401, and a transmission rod 405 is connected between the first slider 406 and the ratchet mechanism.

[0023] The ratchet mechanism includes a ratchet 402, a pawl 403 and a swing arm 404. The ratchet 402 is coaxially arranged at the end of the friction roller 401. One end of the swing arm 404 is rotatably installed at the end of the friction roller 401, and the other end is hinged to one end of the transmission rod 405. One end of the pawl 403 is hinged to the swing arm 404, and the other end is against the ratchet 402. A torsion spring is installed at the hinged end of the pawl 403, so that the pawl 403 leans against the ratchet 402 through the elastic force of the torsion spring.

[0024] like Figure 4 As shown, when the first reciprocating mechanism 407 drives the first slider 406 to move backward, the first slider 406 pulls the swing arm 404 to swing backward through the transmission rod 405, and the swing arm 404 drives the ratchet 402 to rotate clockwise through the pawl 403 (the ratchet 402 rotates clockwise when viewed from top to bottom), and the ratchet 402 drives the friction roller 401 to rotate, and the friction roller 401 pushes the wooden floor forward a set distance by friction; when the first slider 406 moves forward, the swing arm 404 swings forward, the pawl 403 slides over the surface of the ratchet 402, and the ratchet 402 and the friction roller 401 remain stationary, and the above steps are repeated to achieve intermittent movement of the wooden floor. The first reciprocating mechanism 407 is composed of a rotating wheel and an eccentric connecting arm. The rotating wheel is driven by a motor, and the eccentric connecting arm reciprocates to drive the first slider 406 to move. The interval time of the movement of the wooden floor is determined by the rotation speed of the rotating wheel, and the distance of each movement of the wooden floor is determined by the length of the first reciprocating mechanism 407 and the swing arm 404 .

[0025] like Figure 4 and Figure 5 As shown, a damping mechanism 408 is provided at the end of the friction roller 401, and the damping mechanism 408 includes a damping bracket 4081, a first friction disc 4082 and a second friction disc 4083. The damping bracket 4081 is fixed on the back plate 2, the first friction disc 4082 is coaxially arranged at the other end of the friction roller 401, and the second friction disc 4083 is movably arranged on the damping bracket 4081. The first friction disc 4082 fits the second friction disc 4083, and a compression spring is provided on the damping bracket 4081. By providing the damping mechanism 408, the friction roller 401 will not rotate when the pawl 403 slides over the surface of the ratchet wheel 402, so that the wooden floor will not move forward and backward during the non-feeding process, ensuring that the wooden floor maintains a stable processing state.

[0026] The upper and lower sides of the mounting groove 201 are provided with a clamping assembly 409, and the two ends of the friction roller 401 are installed on the clamping assembly 409. The clamping assembly 409 includes a clamping support 4091 fixed on the back plate 2, an adjustment groove provided on the clamping support 4091, a movable seat 4092 movably provided in the adjustment groove, and an adjustment screw 4093 screwed on the clamping support 4091. The roller shaft of the friction roller 401 is rotatably installed on the movable seat 4092, and one end of the adjustment screw 4093 extends into the adjustment groove and is rotatably connected to the movable seat 4092. The pressure applied by the friction roller 401 to the wooden floor is adjusted by rotating the adjustment screw 4093 to ensure that there is sufficient friction between the friction roller 401 and the wooden floor to push the wooden floor forward.

[0027] like Figure 7As shown, the transmission rod 405 includes a first rod body 4051, a second rod body 4052 and an adjusting sleeve 4053. The adjusting sleeve 4053 is screwed to the end of the first rod body 4051, and the adjusting sleeve 4053 and the end of the first rod body 4051 form a sliding cavity 4054 with an adjustable axial length. A limiting slide 4055 is arranged in the sliding cavity 4054. The second rod body 4052 passes through the adjusting sleeve 4053 and is connected to the limiting slide 4055. The other end of the second rod body 4052 is hinged to the swing arm 404.

[0028] When feeding, the first slider 406 moves backward, and the transmission rod 405 pulls the swing arm 404 to swing backward. At this time, the limiting slide 4055 contacts the end of the second rod 4052, and there is a certain distance between the limiting slide 4055 and the end of the first rod 4051. When the first slider 406 returns, the first rod 4051 moves forward following the first slider 406 until the limiting slide 4055 contacts the end of the first rod 4051, thereby reducing the swing amplitude of the swing arm 404, thereby controlling the distance of each movement of the wooden floor, thereby controlling the interval distance of the saw marks on the wooden floor.

[0029] like Figure 3 and Figure 6 As shown, the feeding mechanism 7 includes a second slider 701 and a second reciprocating mechanism 702 . The second slider 701 is disposed on the band saw mounting seat 9 . The second reciprocating mechanism 702 drives the band saw mounting seat 9 to reciprocate through the second slider 701 .

[0030] The structure of the second reciprocating mechanism 702 is the same as that of the first reciprocating mechanism 407, and will not be described again. When the wooden floor moves forward a certain distance, the second reciprocating mechanism 702 drives the band saw mounting seat 9 to approach the wooden floor, and a saw mark is processed on the surface of the wooden floor; when the second reciprocating mechanism 702 drives the band saw mounting seat 9 to move away from the wooden floor, the feeding mechanism 4 pushes the wooden floor to continue to move forward a set distance, and repeats the above steps to process saw marks with a set interval distance on the surface of the wooden floor.

[0031] like Figure 6 As shown, a slide rail 703 is provided on one side of the band saw mounting seat 9, and the slide rail 703 is parallel to the slide slot 101. The second slider 701 is slidably connected to the slide rail 703. Limit blocks 704 are provided at the front and rear ends of the slide rail 703. The second slider 701 moves between the front and rear limit blocks 704 and drives the band saw mounting seat 9 to move. Since the second slider 701 has a certain sliding time between the front and rear limit blocks 704, the band saw blade 5 is maintained for a certain time when sawing the wooden floor, and will not immediately leave the wooden floor when reaching the sawing position, thereby ensuring the processing quality of the saw mark.
