When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0070] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0071] The present application relates to a head module and a cutting table equipped with the head module. Typically, a cutting table is equipped with a movable motion bracket capable of left-right movement along the X-axis and forward and backward movement along the Y-axis. The head module is mounted at the output end of the motion bracket and is driven by the motion bracket to move left-right movement along the X-axis and forward and backward movement along the Y-axis.

[0072] The head module involved in this application is used to install the cutter module and can quickly change different cutter modules. Figure 10 and Figure 11 As shown, the cutter module has a quick-change connection block 181 fixedly connected to its housing. The quick-change connection block 181 is annular in structure. Three circumferentially spaced connection lugs 182 are fixedly provided on the outer periphery of the quick-change connection block 181. The connection lugs 182 integrally extend outward from the outer periphery of the quick-change connection block 181. Two ball screws 183 extending axially up and down are installed in each connection lug 182. Figure 12 As shown, the ball screw 183 has a steel ball 184 that can be extended and retracted up and down. A spring is configured inside the ball screw 183 to abut against the steel ball 184. The spring causes the steel ball 184 at the lower end of the ball screw 183 to emerge downward from the lower end surface of the connecting lug 182, and can also cause the steel ball 184 to retract upward into the ball screw 183.

[0073] like Figure 1 、 Figure 4 、 Figure 5 ,as well as Figures 7 to 9 As shown, the head module of the present invention includes a mounting base 10, a quick-change mounting base 20, a positioning gasket 30 and a pre-tightening O-ring 40; wherein the quick-change mounting base 20 is fixed to the upper end of the mounting base 10, and the quick-change mounting base 20 is provided with a mounting inner hole 21 that passes through from top to bottom, three circumferentially spaced limiting lugs 22, and three slots 23 formed between two limiting lugs 22, the limiting lug 22 extends inward from the inner side of the upper end of the quick-change mounting base 20 as a whole, and the limiting lug 22 and The slots 23 are circumferentially staggered; the locking gasket 30 and the pre-tightening O-ring 40 are both fixed to the quick-change mounting seat 20, and the locking gasket 30 is arranged at the lower end of the quick-change mounting seat 20. The limiting lug 22 at the upper end of the quick-change mounting seat 20 and the locking gasket 30 are arranged opposite to each other up and down, and a mounting cavity is formed between the two; the locking gasket 30 is provided with several concave locking recesses 31 on the upper end surface facing the limiting lug 22, and the pre-tightening O-ring 40 abuts against the lower end surface of the locking gasket 30 facing away from the limiting lug 22.

[0074] When installing the cutter module into the head module, the cutter module is inserted into the mounting inner hole 21 of the quick-change mounting seat 20 from the upper side, and the connecting lug 182 of the quick-change connecting block 181 on the cutter module is aligned with the slot 23 of the quick-change mounting seat 20 on the head module; when the cutter module is inserted downward into place, that is, in the up and down directions, the quick-change connecting block 181 of the cutter module is distributed between the limiting lug 22 and the locking gasket 30 of the head module; then, the cutter module is rotated at an angle so that the connecting lug 182 of the quick-change connecting block 181 is screwed into the side directly below the limiting lug 22, and the steel balls 184 at the lower ends of several ball screws 183 on the cutter module are just locked in the locking recess 31 of the locking gasket 30, so that the connecting lug 182 is located in the mounting cavity of the head module. The limiting lug 22 of the die head module precisely abuts the upper side of the connecting lug 182 of the cutter module, and the locking gasket 30 of the die head module abuts the lower side of the connecting lug 182 of the cutter module. The elastic pre-tightening O-ring 40 provides pre-tightening force, eliminating the axial clearance between the quick-change connecting block 181 and the quick-change mounting seat 20, thereby axially limiting the quick-change connecting block 181 in the die head module and preventing the cutter module from axially moving relative to the quick-change mounting seat 20 of the die head module. When removing the cutter module from the die head module, rotate the cutter module to an angle so that the connecting lug 182 of the quick-change connecting block 181 on the cutter module precisely screws into the slot 23 of the quick-change mounting seat 20 on the die head module. Then, pull the cutter module upward to remove it.

[0075] Therefore, the present application uses the axially spaced limiting lugs 22 and slots 23, as well as the locking gasket 30 and pre-tightening O-ring 40. When installing the cutter module, it is only necessary to align it with the slot 23 and insert it, and then rotate it an angle. This can achieve quick disassembly and installation of the cutter module, and thus can quickly change different cutter modules, thereby improving the product competitiveness of the head module in mid-to-high-end models, and is conducive to the rapid expansion of domestic and overseas single-layer market customers such as clothing, advertising, composite materials, carpets and floor mats. In addition, after the cutter module is installed in the head module, the present application uses the limiting lugs 22 and the locking gasket 30 to axially limit the cutter module, and provides pre-tightening force through the pre-tightening O-ring 40, which reliably limits the cutter module in the installation cavity, prevents the cutter module from axial movement, and improves the assembly reliability of the cutter module in the head module.

[0076] Furthermore, if Figure 9As shown, the quick-change mounting base 20 is fixed to the upper end of the mounting base 10 by a plurality of fixing screws. The fixing structure of the retaining gasket 30 and the pre-tightening O-ring 40 is preferably as follows: the upper end surface of the mounting base 10 is provided with a first mounting groove 101 and a second mounting groove 102 distributed at the lower end of the first mounting groove 101, and the first mounting groove 101 is connected to the second mounting groove 102; the retaining gasket 30 is accommodated in the first mounting groove 101 and is fixedly clamped between the mounting base 10 and the quick-change mounting base 20, and the pre-tightening O-ring 40 is accommodated in the second mounting groove 102 and abuts against the lower end surface of the retaining gasket 30, thereby fixing the retaining gasket 30 and the pre-tightening O-ring 40 to the quick-change mounting base 20.

[0077] Furthermore, if Figure 1 and Figure 3 As shown, the head module also includes a clamping mechanism 50, which includes a clamping housing 51 fixed to the quick-change mounting base 20, a clamping rod 52 movably mounted in the clamping housing 51, and an operating ring 53 fixed to the outer end of the clamping rod 52 and located outside the quick-change mounting base 20. The inner end of the clamping rod 52 can extend from the clamping housing 51 and be placed in the mounting inner hole 21. During assembly and disassembly of the cutter module, the operating ring 53 is used to move the inner end of the clamping rod 52 out of the mounting inner hole 21, thereby preventing interference with the assembly and disassembly of the cutter module. After the cutter module is installed, the operating ring 53 is used to extend the inner end of the clamping rod 52 inward, so that the inner end of the clamping rod 52 only abuts the outer circumferential surface of the quick-change connecting block 181 in the cutter module, more reliably preventing axial movement of the cutter module.

[0078] Furthermore, if Figure 8 and Figure 10 As shown, the cutter module also has a reversing rotating seat 185 that is rotatable relative to its housing, a tool spindle 186 that is installed in its housing and the reversing rotating seat 185 so as to be movable up and down, a cutter 187 installed at the lower end of the tool spindle 186, a torque transmission mechanism 188, and a vibration motor 189 that drives the tool spindle 186 to move up and down. The reversing rotating seat 185 is connected to the tool spindle 186 through the torque transmission mechanism 188, and the reversing rotating seat 185 transmits torque to the tool spindle 186 through the torque transmission mechanism 188. During the cutting process of the cutter module, the vibration motor 189 drives the tool spindle 186 and the cutter 187 at its lower end to move up and down, so that the cutter 187 cuts the cut piece, and the vibration drive source provides the cutting power for the cutter 187. When switching the cutting position, the reversing rotating seat 185 is driven by the head module to rise and fall and rotate, thereby changing the cutting direction of the cutter 187. Based on this, as shown in FIG. Figures 1 to 3As shown, the head module also includes a fixed seat 60, a lifting drive source 70 installed on the fixed seat 60, a lifting connection seat 80 installed on the fixed seat 60 so as to be movable up and down, a rotation drive source 90 installed on the lifting connection seat 80, and a reversing rotation sleeve 110 rotatably supported in the mounting base 10. The fixed seat 60 is used to be fixed on the output end of the motion bracket of the cutting table. The lifting drive source 70 is transmission-connected with the lifting connection seat 80 to drive the lifting connection seat 80 to move up and down. The rotation drive source 90 is transmission-connected with the reversing rotation sleeve 110 to drive the reversing rotation sleeve 110 to rotate. The mounting base 10 is fixed to the lifting connection seat 80 by a number of screws; as shown Figure 6 As shown, a keyway 111 for accommodating a flat key is provided on the inner wall of the reversing rotating sleeve 110 , and the reversing rotating sleeve 110 is key-connected to the reversing rotating seat 185 via the flat key in the keyway 111 .

[0079] When switching the cutting position, the lifting drive source 70 is activated, driving the lifting connection base 80 upward. The lifting connection base 80 then drives the rotary drive source 90, the mounting base 10, the reversing rotating sleeve 110, and the cutter module inserted into the mounting base 10 (i.e., the reversing rotating sleeve 110) and the quick-change mounting base 20 to move upward. The rotary drive source 90 is activated to drive the reversing rotating sleeve 110 to rotate. The reversing rotating sleeve 110 drives the reversing rotating base 185 of the cutter module to rotate by the same angle through the flat key connection. The reversing rotating base 185 then drives the tool spindle 186 and the cutter 187 to rotate by the same angle through the torque transmission mechanism 188. Therefore, the cutting direction of the cutter 187 can be changed by driving the lifting drive source 70 and the rotary drive source 90.

[0080] Preferably, if Figure 8 As shown, the reversing rotating sleeve 110 is rotatably supported in the mounting base 10 by upper and lower bearings. The mounting base 10 is provided with a spacer sleeve 170 between the upper and lower bearings, which abuts against the bearings. There is a gap between the inner circumference of the spacer sleeve 170 and the outer circumference of the reversing rotating sleeve 110; and a limiting member is fixed on the outer circumference of the reversing rotating sleeve 110, which abuts against the lower end of the lower bearing for axial limitation.

[0081] Furthermore, the reversing rotating sleeve 110 is keyed to the reversing rotating seat 185 of the cutting module. Therefore, when replacing different cutting modules, the reversing rotating seat 185 of each cutting module is frequently plugged in and out of the reversing rotating sleeve 110. Therefore, the surface of the reversing rotating sleeve 110 is coated with a titanium nitride coating to increase its hardness and wear resistance, thereby extending its service life and making it durable.

[0082] Furthermore, if Figure 1 and Figure 2As shown, the lifting drive source 70 is connected to the lifting connecting seat 80 through a lifting transmission mechanism; the lifting drive source 70 is a motor, preferably a stepping motor, and the lifting transmission mechanism includes a screw rod 120 extending up and down, and a transmission nut cooperating with the screw rod 120. The motor shaft of the lifting drive source 70 is fixedly connected to the upper end of the screw rod 120 through a coupling, and the screw rod 120 is rotatably supported in the fixed seat 60 through a bearing, and the transmission nut is fixedly connected to the lifting connecting seat 80.

[0083] Preferably, if Figure 1 and Figure 2 As shown, the head module also includes a guide rail 130 parallel to the screw rod 120, and a guide slider fixed to the lifting connecting seat 80. The guide slider slides with the guide rail 130, and the screw rod 120 and the guide rail 130 are arranged side by side along the radial direction of the screw rod 120. This layout is more compact and reasonable, and can reduce the space occupied by the head module in the cutting bed.

[0084] Furthermore, if Figure 2 and Figure 3 As shown, the rotary drive source 90 is connected to the reversing rotating sleeve 110 through a rotary transmission mechanism; the rotary drive source 90 is a motor, preferably a stepping motor, and the rotary transmission mechanism includes a driving pulley 140, a driven pulley 150, and a transmission belt 160 sleeved on the outer circumference of the driving pulley 140 and the driven pulley 150, the driving pulley 140 is fixed on the motor shaft of the rotary drive source 90, and the driven pulley 150 is fixedly connected to the reversing rotating sleeve 110 by several screws.

[0085] Preferably, if Figure 3 As shown, the inner hole of the driven pulley 150 is a positioning hole 151, and the upper end of the reversing rotating sleeve 110 is provided with a positioning section 112 extending into the positioning hole 151. The positioning section 112 is positioned and matched with the positioning hole 151 to achieve the positioning of the driven pulley 150 during installation.

[0086] In summary, the head module of this application enables quick replacement of the cutter module and reliably prevents the cutter module from moving axially up and down. It also drives the tool spindle and cutter in the cutter module to raise and lower, rotate, and change the cutting direction. Therefore, this application enhances the competitiveness of the head module in mid- to high-end machine models, facilitating rapid expansion of domestic and international customers in single-layer markets such as clothing, advertising, composite materials, and carpets and mats. Therefore, this invention effectively overcomes the shortcomings of the prior art and possesses high industrial value.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
