Description

Technical Field

[0001] This utility model relates to the field of paper can precision cutting machine technology, specifically a positioning and anti-deviation structure for a paper can precision cutting machine. Background Technology

[0002] Paper cans are widely used in food, daily chemicals, pharmaceuticals, and electronic components. During the production of paper cans, they need to be cut into different sizes. Paper can cutting equipment is an automated processing device that performs fixed-length and precise cutting of paper cans. Its core function is to cut continuously formed or pre-made paper can blanks into finished products of preset lengths, while ensuring that the cuts are flat and the dimensions are uniform, thus improving the efficiency of paper can production.

[0003] In the prior art, utility model patent application number CN201920059865.3 discloses a snack packaging paper can cutting device, including a frame and a base. The base is fixedly installed on the upper left side of the frame, and a push rod seat is fixedly installed on the upper end of the frame. A stepping electric push rod is fixedly installed on the upper end of the push rod seat. Through the design of the horizontal column, the cutter clamp, the stepping electric push rod, and the electric push rod, the paper tube is cut under the push of the electric push rod. The cutting length of the paper can is controlled by the stepping electric push rod. This snack packaging paper can cutting device has a simple structure and is easy to install and maintain. Through the design of the arc block and the filling layer, the arc block is pushed behind the paper tube under the push of the stepping electric push rod. The filling layer is set on the outer surface of the horizontal column, which can support the paper tube when the paper tube is put on the horizontal column, thereby preventing the paper tube from being dented during cutting. This utility model has good protection and produces products with uniform appearance.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1 like Figures 1-6As shown, a positioning and anti-deviation structure for a paper can precision cutting machine includes a mounting frame 1, a machine body 2, a first mounting base 6, a second lead screw shaft 12, a first linkage shaft 14, a third lead screw shaft 16, and a second linkage shaft 18. The machine body 2 is supported by the mounting frame 1 and has a paper can roller 3. A cutter holder 5 is mounted on the mounting frame 1 above the paper can roller 3. A precision cutting cutter 8 is adjustablely mounted on the cutter holder 5, and a pressure roller 804 is elastically mounted on the precision cutting cutter 8. An adjusting device 10 is adjustablely mounted on the lower end face of the mounting frame 1, and an abutment roller 11 is mounted on the adjusting device 10 below the paper can roller 3. Both the pressure roller 804 and the abutment roller 11 can abut against the outer surface of the paper can roller 3 and rotate with the paper can roller 3. A through groove 20 is also included, with the mounting frame 1 having a through groove 20 corresponding to the position of the paper can roller 3, and the abutment roller 11 is movably disposed in the through groove 20. Additionally, it includes a can-retrieving component 9, which comprises a second threaded sleeve 901, a sliding hole 902, and a notched push ring 903. The equipment body 2 has a first lead screw shaft 4 and a second guide slide rod 21 parallel to the paper can roller 3. The first lead screw shaft 4 is rotatably mounted on the equipment body 2. The second threaded sleeve 901 is threaded onto the first lead screw shaft 4, the sliding hole 902 is slidably mounted on the second guide slide rod 21, and the notched push ring 903 is arranged around the paper can roller 3 without contacting it. The equipment body 2 has a built-in drive unit and control unit. The drive unit includes a servo motor to drive the paper can roller 3 and the first lead screw shaft 4 to achieve stable rotation. The control unit uses a PLC controller, specifically a Siemens S7-200SMARTCPUSR40, which has 14 inputs / 10 outputs digital interfaces, supports pulse output control of the servo motor, and can store more than 200 control programs. The automated process of "feeding detection → positioning and clamping → cutting control → can retrieving and resetting" is realized through programming, and it also has fault diagnosis and alarm functions (such as motor overload, sensor abnormality).

[0022] like Figure 1 , Figure 3 and Figure 5As shown, a pair of second lead screw shafts 12 parallel to the paper can roller 3 are rotatably mounted on the tool holder 5. The same end of the pair of second lead screw shafts 12 is connected by a first linkage shaft 14. One end of one of the second lead screw shafts 12 is connected to a first motor 13. A first bevel gear set 15 is provided at the connection between the second lead screw shaft 12 and the first linkage shaft 14, thereby realizing the synchronous rotation of the pair of second lead screw shafts 12. A first mounting seat 6 is threaded onto the pair of second lead screw shafts 12. The first mounting seat 6 includes a first threaded sleeve 601. The first threaded sleeves 601 corresponding to the pair of second lead screw shafts 12 are provided on both sides of the first mounting seat 6. The first threaded sleeves 601 are threaded onto the corresponding second lead screw shafts 12. A precision cutting tool 8 is lifted and installed below the first mounting seat 6. A first electric telescopic rod 7 is installed on the upper end surface of the first mounting seat 6. The telescopic end of the first electric telescopic rod 7 extends through the first mounting seat 6 to the bottom where the precision cutting tool 8 is installed. The precision cutting tool 8 includes a limiting stage 801, a spring 802, and a sliding plate 803. The limiting stage 801 is fixedly installed on the precision cutting tool 8, and the sliding plate 803 is elastically installed on the lower end face of the limiting stage 801 by the spring 802. Multiple clamping rollers 804 are symmetrically arranged on the lower end face of the sliding plate 803, and the multiple clamping rollers 804 are symmetrically distributed around the cutting edge of the precision cutting tool 8. The precision cutting tool 8 consists of a tool holder and a cutting edge. A limiting platform 801 is located at the upper end of the tool holder. A sliding plate 803 is elastically mounted on the tool holder by a spring 802, and its lower end is limited by the upper end face of the cutting edge. The upper end face of the cutting edge is provided with a planar structure to ensure that the sliding plate 803 will not tilt. This ensures that the sliding plate 803 can drive the pressure roller 804 to stably press against the paper can mounted on the paper can roller 3. Multiple anti-slip rings are arranged sequentially along the length of the outer surface of the pressure roller 804 to increase the axial friction between the paper can and the pressure roller 804. The pressure roller 804 is rotatably mounted, and when it abuts against the paper can, it can rotate with the rotation of the paper can, thus not affecting the normal rotation of the paper can.

[0023] like Figure 1 , Figure 4 and Figure 7As shown, a pair of third lead screw shafts 16 parallel to the paper can roller 3 are rotatably mounted on the lower end face of the mounting frame 1. The same end of the pair of third lead screw shafts 16 is connected by a second linkage shaft 18. One end of one of the third lead screw shafts 16 is connected to a second motor 17. A second bevel gear set 19 is provided at the connection between the third lead screw shaft 16 and the second linkage shaft 18, thereby enabling synchronous rotation of the pair of third lead screw shafts 16. The adjusting device 10 is horizontally movable via the pair of third lead screw shafts 16. The adjusting device 10 includes a second mounting base 1001. A bracket 1002 is mounted on the lower end face of the second mounting base 1001. A second electric telescopic rod 1005 is mounted on the bracket 1002. The telescopic end of the second electric telescopic rod 1005 extends through the second mounting base 1001 and connects to the upper connecting wheel 11. Third threaded sleeves 1003, adapted to a pair of third lead screw shafts 16, are provided on both sides of the second mounting base 1001. The third threaded sleeves 1003 are threaded onto the corresponding third lead screw shafts 16. The connecting wheel 11 includes a base plate 1101. The upper end of the base plate 1101 is symmetrically provided with connecting wheels 11, and the lower end is fixedly provided with multiple first guide slide rods 1102. A sliding sleeve 1004, corresponding one-to-one with each of the first guide slide rods 1102, is provided through the second mounting base 1001. The first guide slide rods 1102 are slidably installed in the sliding sleeves 1004. Multiple anti-slip rings are sequentially arranged on the outer surface of the abutment wheel 11 along its length, thereby increasing the axial friction between the paper can and the abutment wheel 11. The abutment wheel 11 is rotatably mounted; when it abuts against the paper can, it rotates with the paper can, thus not affecting its normal rotation. This, in conjunction with the pressure wheel 804, restricts the axial movement of the paper can, preventing axial movement during cutting and thus avoiding deviation, ensuring the accuracy of the paper can cutting. The anti-slip rings on the outer surfaces of both the pressure wheel 804 and the abutment wheel 11 are made of soft material, which increases friction without damaging the surface of the paper can. The first motor 13 is started, which drives the two second lead screw shafts 12 to rotate synchronously via the first linkage shaft 14. The first mounting base 6 moves horizontally along the lead screw shaft via the first threaded sleeve 601, driving the precision cutting tool 8 to adjust to the preset cutting position (the displacement accuracy is controlled by the motor encoder, with an error of ±0.1mm). Similarly, the second motor 17 is started, which drives the third lead screw shaft 16 to rotate via the second linkage shaft 18. The adjusting device 10 moves horizontally with the second mounting base 1001, ensuring that the abutment wheel 11 is always directly below the cutting position, guaranteeing accurate support. The descent height of the precision cutting tool 8 is finely adjusted by the first electric telescopic rod 7, so that the blade is in contact with the surface of the paper can (the pressure wheel 804 is always in a pressed state by the elastic compression of the spring 802, ensuring that the paper can does not loosen).After cutting, the first electric telescopic rod 7 drives the precision cutting tool 8 to rise, and the second electric telescopic rod 1005 drives the abutment wheel 11 to fall; the first lead screw shaft 4 is started, and the rotation of the first lead screw shaft 4 drives the second threaded sleeve 901 to move horizontally along the second guide slide rod 21, and the notch push ring 903 moves synchronously, pushing the cut paper can product off the paper can roller 3, and completing the can removal.
