Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of edge band slotting, and particularly relates to a furniture board edge band slotting device. BACKGROUND

[0002] The furniture board edge band slotting device comprises left and right parallel cutters and cutter abutting members, and a vertical operation channel is left between the cutters and the cutter abutting members. A vertical edge band is longitudinally threaded through the operation channel, and in this process, the cutter cuts a longitudinal slot line on the surface of the edge band so as to facilitate subsequent bending treatment of the edge band along the longitudinal slot line. The vertical direction is transverse, and the height of the longitudinal slot line is the transverse position. The previous edge band is a standard edge band with consistent specifications, and the transverse positions of the longitudinal slot lines on the standard edge band are consistent, so the cutters of the furniture board edge band slotting device are fixed, but more and more non-standard edge bands have appeared on the market, and the transverse positions of the longitudinal slot lines of different non-standard edge bands are different. The conventional edge band slotting device can only cut a longitudinal slot line at the same transverse position on the surface of the edge band due to the fixed cutters, and thus is not suitable for slotting non-standard edge bands. SUMMARY

[0008] Further, a guide mechanism is arranged on the front side and / or the rear side of the cutters and the cutter abutting members to guide the edge band to be longitudinally threaded along the operation channel.

[0009] Further, the guiding mechanism comprises at least one pair of rotating wheels, the rotating shafts of which are horizontal axes, and a clamping position is left between the two rotating wheels for the edge band to pass through longitudinally, and the two rotating wheels clamp the edge band passing through the clamping position together, so as to guide the edge band to pass through longitudinally along the operation channel.

[0010] Further, the at least one rotating wheel is outwardly convex with a horizontal limiting part for limiting the edge band horizontally.

[0011] Further, the horizontal direction is specifically the up-down direction, and the cutter is driven to ascend and descend by the cutter adjusting mechanism, so as to cut the longitudinal groove line at different heights on the surface of the edge band.

[0012] Further, the horizontal direction is specifically the up-down direction, and the cutter is driven to ascend and descend by the cutter adjusting mechanism, so as to cut the longitudinal groove line at different heights on the surface of the edge band.

[0025] The application will be further described in detail in connection with the specific embodiments.

[0026] The door plate edge strip slotting device is shown in Figure 1 , which comprises a base 10, four guide units 6 are installed on the base 10 in parallel from front to back, each guide unit 6 comprises left and right guide wheels 61, 62, and a clamping position 63 is left between the left and right guide wheels 61, 62, as shown in Figure 2 , the clamping position 63 is equal in width to the door plate edge strip 9 (both widths are H1). A knife holder 7 is provided on the left side between the two middle guide units 6, and a knife abutting member is provided on the right side, which is a knife abutting wheel 2, as shown in Figure 4 , an operation channel 23 is left between the knife 1 and the knife abutting wheel 2, and the distance between the knife tip 11 of the knife 1 and the knife abutting wheel 2, i.e. the minimum width H2 of the operation channel 23, is less than H1. See Figure 1 , a driving mechanism 8 is provided at the front end of the base 10, which comprises a driving wheel 81 and a driven wheel 82, and a driving position 83 is left between the driving wheel 81 and the driven wheel 82, which is equal in width to H1 (see Figure 2 ), the driving mechanism 8 further comprises a driving motor 84 connected to the driving wheel 81 through a synchronous belt. The guide wheels 61, 62, the knife abutting wheel 2, the driving wheel 81 and the driven wheel 82 are all rotating wheels, and the rotating shafts are all vertical shafts (only the rotating shafts L1, L2 of the guide wheels 61, 62 are shown in the figure).

[0027] The front-to-back direction is the longitudinal direction, and the up-to-down direction is the transverse direction. The edge strip 9 is placed longitudinally, and its width direction is the transverse direction (i.e. the up-to-down direction). When slotting, as shown in Figure 1 , the edge strip 9 is manually passed longitudinally through the clamping positions 63 of the two rear guide units 6, the operation channel 23 between the knife 1 and the knife abutting wheel 2, the clamping positions 63 of the two front guide units 6, and the driving position 83 of the driving mechanism 8 from back to front. In this process: the four guide units 6 form a guide mechanism, the left and right guide wheels 61, 62 of each guide unit 6 jointly clamp the edge strip 9 and guide the edge strip 9 to pass longitudinally along the operation channel 23; the knife 1 cuts a longitudinal slot line 91 on the surface of the edge strip 9; and the driving wheel 81 and the driven wheel 82 of the driving mechanism 8 jointly clamp the edge strip 9. The driving motor 8 is started to drive the driving wheel 81 to rotate, and the driving wheel 81 and the driven wheel 82 together drive the edge strip 9 to move forward, in this process, the guide mechanism continues to guide the edge strip 9, and the knife 1 continues to cut a longitudinal slot line 91 on the edge strip 9. See Figure 2, the wheel body 620 of the right guide wheel 62 has two upper and lower transverse limiting portions 621, 622 protruding outward on the top and bottom, the upper transverse limiting portion 621 is above the edge strip 9, and the lower transverse limiting portion 622 supports the edge strip 9, thereby transversely limiting the edge strip 9 to prevent the edge strip 9 from moving transversely when the groove is cut. See Figure 1 , the cutter wheel 2 has the same structure as the right guide wheel 62 and will not be described again. After the groove is cut, the edge strip 9 can be bent along the longitudinal groove line 91, so that it can be attached to the edge of the door panel for edge sealing.

[0028] See Figure 1 , the present cutting device is suitable for cutting grooves in non-standard edge strips 9. Different non-standard edge strips 9 have different heights (i.e. transverse positions) of the longitudinal groove line 91. The cutter holder 7 of the present cutting device is provided with a cutter adjusting mechanism 3, which manually drives the cutter 1 to rise and fall to change the height of the cutter 1, so that the cutter 1 can cut the longitudinal groove line 91 at different heights on the surface of the edge strip 9. See Figure 3 , the cutter holder 7 includes an upper holder body 71 and a lower holder body 72 mounted together, and the inside of the lower holder body 72 is provided with a mounting cavity 721, and the bottom of the upper holder body 71 is provided with a transmission cavity 711, and the top wall 722 of the lower holder body 72 serves as the bottom wall of the transmission cavity 711. The cutter adjusting mechanism 3 includes a hand wheel 31, a transmission shaft 32, and a screw-nut transmission pair 33. The hand wheel 31 is rotatably mounted on the right wall 723 of the lower holder body 72, the outward end 311 thereof is exposed to the left side of the mounting cavity 721, and the inward end 312 thereof is located in the mounting cavity 721 and is provided with a first bevel gear 313. The transmission shaft 32 is rotatably mounted on the top wall 722 of the lower holder body 72, the lower part 321 thereof extends downward into the mounting cavity 721 and is provided with a second bevel gear 323 engaged with the first bevel gear 313, and the upper part 322 thereof extends upward into the transmission cavity 711 and is provided with a first transmission gear 324. The screw-nut transmission pair 33 is a prior art, which is located in the transmission cavity 711 and includes a screw rod 331 and a nut 332 sleeved on the screw rod 331. The screw rod 331 is fixedly provided with a second transmission gear 334 engaged with the first transmission gear 324, and the screw rod 331 is blocked by the top wall 710 and the bottom wall 722 of the transmission cavity 711, so that it can only rotate around its own axis but cannot move laterally. The screw-nut transmission pair 332 is blocked by the side wall 715 of the transmission cavity 711, so that it can only move laterally but cannot rotate. The upper holder body 71 is provided with a vertical sliding groove 716 on the top, the screw-nut transmission pair 332 extends upward and is provided with a connecting rod 333, the upper end of the connecting rod 333 extends upward out of the transmission cavity 711 and extends into the vertical sliding groove 716, and the cutter 1 is mounted on the connecting rod 333. The distance H3 between the upper and lower transverse limiting portions 621, 622 is 100 mm, and the present cutting device is suitable for cutting grooves in non-standard edge strips 9 with a width of 18-100 mm, but if the width of the edge strip 9 is less than 100 mm, the transverse limiting effect of the upper and lower transverse limiting portions 621, 622 on the edge strip 9 will be poor.

[0029] See Figure 3 When the height of the cutting knife 1 needs to be adjusted, the hand wheel 31 is manually rotated to drive the transmission shaft 32 to synchronously rotate the lead screw 331, which drives the lead screw nut 332 to ascend or descend, thereby indirectly driving the cutting knife 1 to ascend or descend. One clockwise rotation of the hand wheel 31 raises the cutting knife 1 by 5 mm, and one counterclockwise rotation of the hand wheel 31 lowers the cutting knife 1 by 5 mm. See Figure 5 The lower bracket body 72 is correspondingly provided with a counter 73, the right part 312 of the hand wheel 31 is provided with a third transmission gear 315, the left end of the counter 73 is an exposed display part 731, the right end of the counter 73 is provided with a fourth transmission gear 735 engaged with the third transmission gear 315, and the counter 73 is internally provided with a counter (not shown in the figure) connected with the fourth transmission gear 735. When the hand wheel 31 is rotated, the counter in the counter 73 is synchronously driven to move, thereby changing the reading of the display part 731 of the counter 73. The operator can know the number of rotations of the hand wheel 31 by observing the reading of the counter 73, and thus indirectly infer how much distance the cutting knife 1 has ascended or descended.

[0032] The embodiment is shown in Figure 1 , the front end of the base 10 is provided with a driving mechanism 8 for driving the edge strip 9 to move forward in the longitudinal direction. Other embodiments are shown in Figure 6 , the driving mechanism 8 can cancel the driving wheel and the driven wheel, and the driving motor 84 can be changed into driving the left guide wheel 61. The left guide wheel 61 is driven to rotate by the driving motor 84, and the left guide wheel 61 and the right guide wheel 62 together drive the edge strip 9 to move forward, thereby driving the edge strip 9 to move forward.
