[0001] The utility model relates to the technical field of textile equipment, in particular to a punching tooth cutter head with axially double-row knife holes. Background Technique

[0002] At present, the punching tooth cutter head has a single hole and can only install a single knife to realize the punching production of a single tooth profile card clothing. In actual production requirements, the card clothing tooth profile to be produced is complex, and there are slight deformations after the die grinding. The single-hole cutter head cannot adjust the double-tooth gap simultaneously, and it is necessary to rework the grinding to adjust the gap, which is difficult to grind.

[0003] In the document CN202321189072, a die grinding device for metallic card clothing is disclosed, which includes a transmission mechanism and a grinding tooling. The characteristics are that the transmission mechanism is a way of driving the rotating shaft by a motor, a synchronous pulley, and a synchronous belt. The grinding tooling includes a connecting sleeve and a cutter head cover. The cutter head cover is fixedly connected to the cutter head through a fastener. The cutter head and the connecting sleeve are fixedly connected through a connecting piece, and a clamping plate is installed on the cutter head cover; the connecting sleeve is installed on the rotating shaft through a mounting piece; longitudinal grooves and transverse grooves are opened on the cutter head cover, and the clamping plate is located above the transverse groove. When grinding with this structure, since it is unilateral, the efficiency is low.

When the die has slight deformation after grinding, the die in the knife hole can be adjusted through the adjusting bolt on the vertical block, improving the grinding efficiency of the card clothing.

[0006] The technical solution of the utility model is as follows: a punching tooth cutter head with axially double-row knife holes, including end covers provided on both sides of the cutter head body. The end covers are connected to the cutter head body through die seats. The die seats on both sides of the cutter head body are rotationally symmetric with the cutter head body as the center point. The die seat includes a vertical block and a horizontal block. A knife hole is provided on the vertical block, and a die is fitted in the knife hole. A groove body adapted to the die seat is provided in the cutter head body, and the center points of the groove bodies on both sides of the cutter head body are rotationally symmetric.

[0007] By adopting the above technical solution, the die is installed in the knife hole, and then the position of the die in the knife hole is axially adjusted through the adjusting bolt. The bolt on the cutter head body fixes the horizontal block, thereby fixing the die seat, and then the end cover is closed and the whole is tightened.

[0008] Preferably, the knife hole is located at the axial position of the vertical block. The knife hole is larger than the size of the die. An adjusting bolt perpendicular to the knife hole is provided on the side of the vertical block, and the adjusting bolt is used to adjust the horizontal position of the die in the knife hole.

[0009] By adopting the above technical solution, the adjusting bolt of the cutter head body can be adjusted to change the lateral position of the cutter die in the cutter hole, so as to better adapt to the grinding of the card clothing and improve the grinding efficiency of the card clothing.

[0010] Preferably, the groove body includes a transverse groove and a longitudinal groove. The transverse grooves are uniformly arranged on both sides of the cutter head body, and the longitudinal grooves on both sides of the cutter head body are arranged staggeredly on the cutter head body. The longitudinal grooves penetrate the surface of the cutter head body, the depth of the longitudinal grooves is greater than the transverse width of the vertical block, and the transverse grooves penetrate the axial direction of the cutter head body.

[0011] By adopting the above technical solution, the transverse grooves are placed staggeredly on the cutter head body and are rotationally centrosymmetric, so that the transverse block on one side of the cutter head body is located on the side of the vertical block on the other side away from the transverse block, and the position of the cutter die seat is reasonably arranged on the limited cutter head body.

[0012] Preferably, bolt holes penetrate through the circumference of the cutter head body above the transverse grooves. The transverse blocks in the transverse grooves are fixed by bolts in the bolt holes, and threaded holes for fixing the bolts are axially provided on the transverse blocks.

[0013] By adopting the above technical solution, the transverse blocks inserted into the transverse grooves are fastened by the bolts on the cutter head body, that is, the whole cutter die seat is fastened to prevent the cutter die seat from slipping out of the groove body.

[0014] Preferably, the transverse blocks are perpendicular to the cutter holes in space and are located on the side edges of the vertical blocks, and the transverse blocks and the vertical blocks are integrally cross-shaped in space.

[0015] By adopting the above technical solution, the transverse blocks are connected to the vertical blocks. While the transverse blocks are fixed, the vertical blocks are also fixed.

[0016] Preferably, one end of the transverse block is located in the transverse groove of the groove body, the other end abuts against the outer end cover, and the cutter die in the cutter hole penetrates the transverse groove.

[0017] By adopting the above technical solution, the transverse blocks penetrate the axial direction position of the cutter head body and are fastened by bolts, which can effectively fix the whole cutter die seat.

[0018] Preferably, screw holes for adapting to the long-head bolts of the end cover are provided on the circumferential direction of the side surface of the cutter head body, long-head bolts are provided at the positions corresponding to the screw holes on the end cover, and through holes for the adjusting bolts to pass through are also provided on the end cover.

[0019] By adopting the above technical solution, after the long-head bolts pass through the through holes on the end cover, the end cover is fixed to the side of the cutter head body, and both ends of the transverse block just abut against the end cover, playing a role in fixing the transverse block and preventing the transverse block from shifting.

[0020] Preferably, through grooves are provided at the axial center positions of the end cover and the cutter head body, which is convenient for later installation and rotation.

[0021] Advantages of the present utility model: 1. The present utility model is provided with a knife hole on the vertical block for installing a knife die. When the knife die has slight deformation after grinding, the adjusting bolt on the side of the vertical block can radially adjust the knife die, thereby changing the gap between the knife die and the knife hole, realizing the adjustment of the double-tooth gap, adapting to the grinding of different card clothing, and improving the grinding accuracy.

[0022] 2. The knife die seats of the present utility model are rotationally symmetric about the center point on both sides of the knife disc body. The cross block on one side of the knife disc body is located at a position far from the cross block of the vertical block on the other side. In this way, the installation of the knife die seats on both sides can be achieved without a relatively thick knife disc body. Due to the axial double-row action, the punching tooth knife disc with axial double-row knife holes is more than twice that of the prior art. When the spindle speed remains unchanged, the punching tooth speed is doubled.

[0023] 3. The same or different dies can be installed in the knife holes on both sides of the knife disc body of the present utility model, which can realize the punching of different card clothing, improve the grinding effect of the card clothing, and improve the work efficiency.

[0031] As Figures 1 - 6As shown in the figure, a punching tooth cutter disc with axially double-row cutter holes includes end covers 7 provided on both sides of the cutter disc body 1. The end covers 7 are connected to the cutter disc body 1 through die holders 3. A through groove 10 is provided at the axial center position of the end cover 7 and the cutter disc body 1 to facilitate its later installation and rotation. The die holders 3 on both sides of the cutter disc body 1 are rotationally symmetric with the cutter disc body 1 as the center point. The die holder 3 includes a vertical block 5 and a horizontal block 4. A cutter hole 5-1 is provided on the vertical block 5, and a cutter die 5-1 is fitted in the cutter hole 5-1. A groove body 2 adapted to the die holder 3 is provided in the cutter disc body 1. The center points of the groove bodies 2 on both sides of the cutter disc body 1 are rotationally symmetric. By installing the cutter die 5-2 in the cutter hole 5-1 and then axially adjusting the position of the cutter die 5-2 in the cutter hole 5-1 through an adjusting bolt 6, the bolt 9 on the cutter disc body 1 fixes the horizontal block 4, thereby fixing the die holder 3, and then closing the end cover 7 and tightening the whole.

[0032] The cutter hole 5-1 is located at the axial position of the vertical block 5. The cutter hole 5-1 is larger than the size of the cutter die 5-2. An adjusting bolt 6 perpendicular to the cutter hole 5-1 is provided on the side of the vertical block 5. The adjusting bolt 6 is used to adjust the lateral position of the cutter die 5-2 in the cutter hole 5-1. By adjusting the adjusting bolt 6 of the cutter disc body 1, the lateral position of the cutter die 5-2 in the cutter hole 5-1 can be changed, so as to better adapt to the grinding of the card clothing and improve the grinding efficiency of the card clothing.

The depth of the longitudinal groove 2-2 is greater than the transverse width of the vertical block 5. The transverse groove 2-1 penetrates the axial direction of the cutter disc body 1. The transverse grooves 2-1 are staggeredly placed and rotationally centrosymmetric on the cutter disc body 1. In this way, the horizontal block 4 on one side of the cutter disc body 1 is located at the position on the other side away from the horizontal block 4 of the vertical block 5, and the position of the die holder 3 is reasonably arranged on the limited cutter disc body 1.

The bolt 9 on the cutter disc body 1 tightens the horizontal block 4 inserted into the transverse groove 2-1, that is, tightens the whole die holder 3 to prevent the die holder 3 from slipping out of the groove body 2.

[0035] The horizontal block 4 is perpendicular to the cutter hole 5-1 in space and is located on the side of the vertical block 5. The horizontal block 4 and the vertical block 5 are integrally cross-shaped in space. When the horizontal block 4 is fixed, the vertical block 5 is also fixed.

[0036] One end of the cross block 4 is located in the transverse groove 2-1 of the groove body 2, and the other end abuts against the outer end cover 7. The die 5-2 in the die hole 5-1 penetrates through the transverse groove 2-1. The cross block 4 penetrates through the axial direction position of the cutter head body 1.

At the position corresponding to the screw holes 2-4 on the end cover 7, there are long head bolts 8. On the end cover 7, there is also a through hole 7-1 for the adjusting bolt 6 to pass through. After the long head bolts 8 pass through the through hole 7-1 on the end cover 7, the end cover 7 is fixed on the side of the cutter head body 1, and both ends of the cross block 4 just abut against the end cover 7, playing a role in fixing the cross block 4 and preventing the cross block 4 from displacing.

[0038] Insert the die 5-2 into the die hole 5-1 of the vertical block 5, and according to the actual production needs, adjust the adjusting bolt 6 on the vertical block 5 to adjust the axial clearance of the die 5-2 in the die hole 5-1. Fix the cross block 4 by the bolts 9 on the cutter head body 1, so as to fix the cross block 4, and then fix the whole die holder 3 in the groove body 2. Then, pass the through hole 7-1 on the end cover 7 through the adjusting bolt 6 on the vertical block 5, and screw the long head bolts 8 through the end cover 7 into the screw holes 2-4 of the cutter head body 1 to realize the overall assembly.
