Description

Technical Field

[0001] This utility model relates to a knife sharpening machine, and more particularly to a hosiery knives sharpening machine. Background Technology

[0002] A sock machine blade sharpening machine is a device for sharpening two types of blades on sock machines: disc scissors and axe blades. Existing sock machines generally rely on a two-axis platform for manual feeding, and the operator has to observe and rely on their own experience to control the contact and separation of the blade and the grinding wheel, which is inconvenient to control. Utility Model Content

[0003] The purpose of this invention is to provide a hosiery machine knife sharpening machine, which has the advantages of simplified operation and convenient control of the sharpening process.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A hosiery knives sharpening machine includes a motor, a housing, and a disc scissors sharpening unit and / or an axe sharpening unit. The disc scissors sharpening unit includes a sharpening disc fixed to one end of the output shaft of the motor, a mounting plate for mounting the disc scissors, a motor driving the mounting plate to rotate, and a two-axis platform for moving the motor. The two-axis platform includes a front-to-back moving mechanism and a left-to-right lead screw mechanism. One end of the lead screw of the lead screw mechanism is connected to a motor. The axe sharpening unit includes a sharpening disc fixed to one end of the output shaft of the motor, a fixing frame for fixing the axe, and a two-axis platform for moving the fixing frame. The two-axis platform includes a front-to-back moving mechanism and a left-to-right lead screw mechanism. One end of the lead screw of the lead screw mechanism is connected to a motor. The housing is also equipped with a detection module that measures the current of the motor and controls the motors to stop.

[0006] Using the above technical solution, motors three and four are used to control the contact and separation between the grinding tool and the corresponding grinding disc. The detection module controls the stopping of motors three and four. Taking a disc shear as an example, motor three brings the disc shear closer to the grinding disc. When the disc shear contacts the grinding disc, friction is generated, which increases the current of motor one. The detection module detects the current fluctuation and stops motor three. After the disc shear grinds for a certain period of time, motor three advances again to further grind the disc shear. Similarly, the detection module controls motor three to stop. After this cycle is repeated twice, the grinding is completed.

[0007] Preferably, the device includes both a disc scissors sharpening unit and an axe sharpening unit, with the disc scissors sharpening unit and the axe sharpening unit respectively located on the left and right sides of the motor. The other end of the lead screw of the first lead screw mechanism is fixedly equipped with a handwheel, and the other end of the lead screw of the second lead screw mechanism is fixedly equipped with a handwheel.

[0008] By adopting the above technical solution, the handwheel is retained, which can also be manually adjusted when necessary.

[0009] Preferably, both the lead screw mechanism 1 and the lead screw mechanism 2 include a base 1 fixed to the housing and an adapter block 1. The top surface of the base 1 is provided with a protrusion 1, and the bottom surface of the adapter block 1 is provided with a matching groove 1. The base 1 is provided with an installation groove 1 at the position of the protrusion 1. The lead screw 1 and the lead screw 2 are rotatably connected to the corresponding installation groove 1. The bottom surface of the adapter block 1 is provided with a protrusion 1 that matches the installation groove 1. The protrusion 1 is provided with a threaded through hole. The handwheel 1 and the handwheel 2 are fixed at the ends of the lead screw 1 and the lead screw 2 away from the motor.

[0010] Using the above technical solution, the motor drives the lead screw to rotate, and the rotation of the lead screw causes the adapter block to move.

[0011] Preferably, the second moving mechanism includes a sixth motor and a first mounting block. The top surfaces of the first mounting block and the corresponding first transfer block are slidably connected, and the rear side of the first transfer block is provided with a second motor mounting bracket. The sixth motor and the second motor mounting bracket are fixedly connected, and the output shaft of the sixth motor faces upward and is fixedly connected to a rotating disk. A hinge strip is provided between the rotating disk and the first mounting block.

[0012] Using the above technical solution, motor six drives the rotating disk to rotate, and the mounting block one slides through the hinge bar.

[0013] Preferably, the moving mechanism includes a motor, a lead screw, and a mounting block. The top surface of the corresponding adapter block is fixedly connected to the adapter block, which has a protrusion. The bottom surface of the mounting block has a matching groove, and the corresponding adapter block has a mounting groove for mounting the lead screw at the protrusion. The bottom surface of the mounting block has a protrusion that matches the mounting groove, and the protrusion has a threaded through hole. The front end of the lead screw is fixedly connected to a handwheel, and the rear end is fixedly connected to the motor.

[0014] Using the above technical solution, the motor drives the lead screw to rotate, and the rotation of the lead screw causes the second adapter block to move.

[0015] Preferably, the ends of the lead screws of lead screw mechanism one and lead screw mechanism two near the motor are fixedly connected to gears, and the housing is provided with motor mounting bracket one below the two gears. Motor three and motor four are fixedly connected to the corresponding motor mounting bracket one.

[0016] By adopting the above technical solution, the space is made reasonable and the orientation of handwheel one and handwheel two is arranged to facilitate use.

[0017] Preferably, the motor mounting bracket is L-shaped, and the vertical part of the motor mounting bracket is provided with four waist-shaped grooves for mounting the motor.

[0018] Using the above technical solution, motor three and motor mounting bracket one are connected by bolts. The output shaft of motor three is also fixedly connected to gears. Then, motor three is moved up and down along the waist groove to straighten the gear belt between the two gears, thus completing the connection.

[0019] Preferably, the ends of lead screw 1 and lead screw 2 that connect to handwheel 1 and handwheel 2, and the end of lead screw 3 that connects to handwheel 3 are all provided with raised rings, and bearings are fitted on both sides of the raised rings.

[0020] By adopting the above technical solution, a bearing will play a role in ensuring smooth rotation, whether the lead screw 1, lead screw 2, or lead screw 3 rotates forward or backward. Attached Figure Description

[0031] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model. It should also be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.

[0032] like Figure 1 As shown, a hosiery knives sharpening machine includes a motor 2 and a housing 1, with the motor 2 and housing 1 fixedly connected. Because the motor 2 can be a dual-head motor, the sharpening machine simultaneously includes a disc scissors sharpening unit 2-1 and an axe sharpening unit 2-2, with the disc scissors sharpening unit 2-1 and the axe sharpening unit 2-2 respectively located on the left and right sides of the motor 2. Thus, the sharpening machine can sharpen both disc scissors and axe knives.

[0033] The disc shear grinding unit 2-1 includes a grinding disc 3, a mounting plate 4, a motor 5, and a two-axis platform 1 that drives the motor 5. The grinding disc 3 is fixedly connected to one end of the output shaft of the motor 2. Because coolant is needed during the grinding of the disc shears, a housing 1 has a box 011 at the position of the grinding disc 3, placing the grinding disc 3 inside the box 011. A nozzle is fixed on the box 011. A coolant outlet is located at the bottom of the box 011, and a collection tank is located below the outlet to circulate the coolant.

[0034] like Figure 2 indivual Figure 3As shown, motor 2 (5) and the two-axis moving platform are located on the side of housing 011 away from motor 2 (2). To facilitate the movement of motor 2 (5), a rectangular through groove 012 is provided on the side wall of housing 011 away from motor 2 (2). L-shaped guide rails are provided on the upper and lower edges of the rectangular through groove 012. A rectangular plate 013 is slidably connected within the two guide rails, and the rectangular plate 013 has through holes. The output shaft of motor 2 (5) passes through the through holes of the rectangular plate 013 and enters housing 011. The mounting plate 4 is located inside housing 011 and is fixedly connected to the output shaft of motor 2 (5). Thus, when motor 2 (5) moves back and forth, it will drive the rectangular plate 013 to move back and forth.

[0035] The two-axis platform includes a moving mechanism and a lead screw mechanism. The moving mechanism drives the motor 25 to move back and forth, and the lead screw mechanism drives the motor 25 to move left and right. The lead screw mechanism includes a base 6 fixed to the housing 1, an adapter block 7, and a lead screw 8.

[0036] The lead screw mechanism includes a base 6, an adapter block 7, and a lead screw 8 fixed to the housing 1. The top surface of the base 6 has a protrusion with an inverted trapezoidal cross-section. The bottom surface of the adapter block 7 has a mating groove. One side of the groove's inclined inner wall fits snugly against the protrusion, while the other side's inclined inner wall has a gap with the protrusion. A insert is engaged between them. Several bolts are bolted to the other side's inclined inner wall, and the insert has recessed holes for the bolts near the inclined inner wall. This allows the friction between the adapter block 7 and the base 6 to be adjusted via the bolts.

[0037] The base 6 has a mounting groove 61 at the protrusion. The lead screw 8 is rotatably connected to the mounting groove, and both ends of the lead screw 8 protrude from the base 6. The bottom surface of the adapter block 7 has a protrusion 71 that matches the mounting groove 61, and the protrusion 71 has a threaded through hole. In this way, when the lead screw 8 rotates, it can drive the adapter block 7 to move.

[0038] like Figure 4 and Figure 5 As shown, a handwheel 81 is provided at the end of the lead screw 8 away from the motor 2, which can be manually rotated to adjust the adapter block 7. A motor 3 11 is connected to the end of the lead screw 8 near the motor. To make efficient use of space, the motor 3 11 is configured as follows: a gear is fixedly connected to the end of the lead screw 8 near the motor 2; a motor mounting bracket 10 is provided below the gear in the housing 1. The motor mounting bracket 10 is L-shaped, and its vertical portion has four slots for mounting the motor. The motor 3 11 and the motor mounting bracket 10 are connected by bolts. The output shaft of the motor 3 11 is also fixedly connected to a gear. Then, the motor 3 11 is moved up and down along the slots to flex the gear belt between the two gears, completing the connection.

[0039] The moving mechanism includes a motor 5 12, a lead screw 3 13, and a mounting block 2 14 for fixing the motor 2 5. A transition block 2 15 is fixedly connected to the top surface of the transition block 1 7 of the lead screw mechanism. The transition block 2 15 has a protruding portion 2, and the bottom surface of the mounting block 2 14 has a matching groove portion 2 (the shapes of the protruding portion 2 and the groove portion 2, and their arrangement, refer to the protruding portion 1 and the groove portion 1). The transition block 2 15 has a mounting groove 2 151 for mounting the lead screw 3 13 at the position of the protruding portion 2. The output shaft of the motor 5 12 extends into the mounting groove 2 151 from the rear, and the output shaft of the motor 3 11 is fixedly connected to a connecting sleeve. The rear end of the lead screw 3 13 is inserted into the connecting sleeve, and a keyway is provided at the rear end of the lead screw 3 13, with a key fixed to the inner wall of the connecting sleeve, enabling the motor 3 11 to drive the rotation of the lead screw 3 13. A handwheel 3 131 is fixedly provided at the front end of the lead screw 3 13, allowing the lead screw 3 13 to be rotated manually. The bottom surface of mounting block 2 14 is provided with protrusion 2 141 that matches mounting groove 2 151. Protrusion 2 141 is provided with threaded through hole, that is, rotating screw 3 13 will drive mounting block 2 14 to move back and forth.

[0040] like Figure 6 and Figure 7 As shown, the axe sharpening unit 2-2 includes a second sharpening disc 20, a fixed frame 16, and a second two-axis platform 2 that moves the fixed frame 16. The second sharpening disc 20 is fixed to the other end of the output shaft of the second motor 5, and the first motor 2 is also fixed with an arc-shaped baffle along the second sharpening disc 20. The fixed frame 16 has an insertion slot 161, and the top of the insertion slot 161 has a threaded hole. The axe is inserted into the insertion slot 161, and the bolt is tightened to fix the axe. The second two-axis platform 2 includes a second moving mechanism and a second lead screw mechanism, wherein the second moving mechanism drives the fixed frame 16 to move back and forth, and the second lead screw mechanism drives the fixed frame 16 to move left and right.

[0041] Screw mechanism two has the same structure as screw mechanism one, and its configuration can be referenced from screw mechanism one. For ease of distinction, the screw of screw mechanism two is labeled as screw two, the handwheel on screw two is labeled as handwheel two 22, and the motor driving screw two is labeled as motor four. For example... Figure 8 and Figure 9 As shown, the ends of lead screw 1 (8), lead screw 2 (connecting to handwheel 1 (81), and handwheel 2 (22), and the end of lead screw 3 (13) (connecting to handwheel 3 (131)) are all provided with raised rings 23, and bearings 24 are fitted on both sides of the raised rings 23. In this way, whether lead screw 1 (8), lead screw 2 (2), or lead screw 3 (13) rotates forward or backward, a bearing 24 will always be in operation to ensure smooth rotation.

[0042] The second moving mechanism includes a motor 17 and a mounting block 18 for fixed connection to the fixed frame 16. The mounting block 18 and the top surface of the adapter block 7 of the second screw mechanism are slidably connected. The rear side of the adapter block 7 is also provided with a motor mounting frame 21. The motor 17 and the motor mounting frame 21 are fixedly connected, and the output shaft of the motor 17 faces upward and is fixedly connected to a rotating disk 171. A hinge strip 181 is provided between the rotating disk 171 and the mounting block 18. To facilitate the connection between the rotating disk 171 and the mounting block 18, ball joint bearings 24 are threadedly fixed to both ends of the hinge strip 181, and then the ball joint bearings 24 are connected to the rotating disk 171 and the mounting block 18.

[0043] The housing 1 is also equipped with a detection module 19. The detection module 19 measures the current of motor 2 and controls motors 11 and 4 to stop. Taking a disc shear as an example, motor 11 brings the disc shear closer to the grinding disc 3. When the disc shear contacts the grinding disc 3, friction is generated, which increases the current of motor 2. The detection module 19 detects the current fluctuation and stops motor 11. After the disc shear grinds for a certain period of time, motor 11 moves forward again to further grind the disc shear. Similarly, the detection module 19 controls motor 11 to stop. After this cycle is repeated twice, the grinding is completed, and motor 11 moves the disc shear away from the grinding disc 3.
