[0027] The following is combined with Figure 1-6 The present application is further described in detail. An embodiment of the present application discloses a cutting knife adjustment device.

[0028] Example 1

[0029] Reference Figure 1 As shown, a cutting blade adjustment device includes a case 100, a cutting shaft 120 and a blade, wherein the case 100 is provided with an inner cavity 110 extending through the case 100 in a horizontal direction. The cutting shaft 120 is arranged inside the case 100, that is, the two ends of the cutting shaft 120 are rotatably arranged on the side walls of the inner cavity 110. The blade is fixedly connected to the circumferential side wall of the cutting shaft 120, and the cutting surface of the blade is the section of the cutting shaft 120, and the blade edge is extended along the radial direction of the cutting shaft 120. A horizontal adjustment component 200 for adjusting the horizontal movement of the cutting shaft 120 along its axial direction is provided at one end of the cutting shaft 120. A height adjustment component 300 for adjusting the rotation of the cutting shaft 120 is provided at the other end of the cutting shaft 120.

[0030] In the embodiment of the present application, the setting of the chassis 100 facilitates the connection with the existing wire-cutting equipment, so as to facilitate the base fabric / sling / surrounding bag / container bag / woven bag and other series of products to pass through the inner cavity 110 of the chassis 100. Among them, the height adjustment component 300 realizes the position movement of the blade in the height direction by adjusting the rotation of the wire-cutting shaft 120, and then realizes the adjustment movement of the blade in the height direction and the horizontal direction through the cooperation of the horizontal adjustment component 200.

[0031] Reference Figure 2 and Figure 3 As shown, the height adjustment assembly 300 includes a second worm 330 and a second connection seat 310. The second connection seat 310 is fixedly connected to the inner wall of the chassis 100, and its connection method includes but is not limited to welding, integral setting, and fixed connection with bolts. In addition, during the use of some wire-cutting devices, the adjustable wire-cutting shaft 120 can be installed on the wire-cutting device without using the chassis 100, thereby improving the applicability of the wire-cutting blade.

[0032] Two second mounting seats 320 are fixedly connected to the side of the second connection seat 310 facing away from the inner wall of the chassis 100, and the two second mounting seats 320 are respectively fixedly connected to the side facing away from the inner wall of the chassis 100. The two second mounting seats 320 are respectively fixedly connected to the second connection seat 310 by bolts. The second worm 330 is rotatably arranged on the second mounting seats 320, and the two ends of the second worm 330 are correspondingly rotatably arranged on the two second mounting seats 320, and the second worm 330 is arranged in a vertical direction.

[0033] The end of the second worm 330 is fixedly connected to the second rotating disk 340 , and the second rotating disk 340 is fixedly connected to the lower end of the second worm 330 , so that the second worm 330 is driven to rotate by rotating the second rotating disk 340 .

[0034] The height adjustment assembly 300 also includes a positioning shaft 370 and a second worm gear 350. The positioning shaft 370 is fixedly connected to the end of the wire cutting shaft 120, and the positioning shaft 370 is coaxially fixedly connected to the wire cutting shaft 120. The end of the positioning shaft 370 away from the wire cutting shaft 120 is rotatably arranged on the second connecting seat 310, and the positioning shaft 370 passes through the second connecting seat 310 and the box body in sequence. The second worm gear 350 is sleeved on the positioning shaft 370, and the second worm gear 350 is coaxially arranged with the positioning shaft 370. In addition, a stopper 360 for connecting the second worm gear 350 is arranged on the positioning shaft 370.

[0035] The limiting member 360 is a positioning pin. A positioning groove 371 is provided on the positioning shaft 370, and the length direction of the positioning groove 371 extends along the axial direction of the positioning shaft 370. A limiting groove 351 is provided on the inner wall of the second worm gear 350, and the length extension direction of the limiting groove 351 extends along the axial direction of the second worm gear 350. When the second worm gear 350 is sleeved on the positioning shaft 370, the limiting groove 351 is arranged opposite to the positioning groove 371, and the length of the positioning groove 371 is greater than the length of the limiting groove 351.

[0036] During this connection process, the positioning pin is embedded in the limiting groove 351 and the positioning groove 371, thereby limiting the second worm gear 350 from rotating around the positioning shaft 370, and in this process, the positioning shaft 370 can also be pushed to move along the axial direction of the second worm gear 350.

[0037] The second worm wheel 350 and the second worm 330 are meshed with each other, so that during use, the second turntable 340 is rotated to drive the second worm 330 to rotate, and the rotating second worm 330 is meshed with the second worm wheel 350 to drive the second worm wheel 350 to rotate. In this way, through the restriction of the positioning pin, the positioning shaft 370 rotates synchronously with the rotation of the second worm wheel 350, and the rotating positioning shaft 370 drives the wire cutting shaft 120 to rotate, so that the wire cutting shaft 120 drives the blade to rotate. In this process, the position of the blade edge is adjusted and changed in the height direction.

[0038] In this process, the engagement of the second worm gear 350 and the second worm 330 can realize the adjustment of any position in the height direction of the blade, reducing the problem of inflexible adjustment, and the power transmission is realized by rotating the second rotating disk 340, so as to facilitate the height adjustment of the blade. And the self-locking principle of the second worm gear 350 and the second worm 330 is used to ensure the stability of the blade during use.

[0039] Reference Figure 4 and Figure 5 As shown, the level adjustment assembly 200 includes a threaded shaft 220 and a ring 230. The threaded shaft 220 is coaxially fixedly connected to the end of the cutting shaft 120 away from the positioning shaft 370. The ring 230 is sleeved on the threaded shaft 220, and the ring 230 and the threaded shaft 220 are meshed with each other.

[0040] The level adjustment assembly 200 further includes a first connection seat 210 and a first worm gear 240. The first connection seat 210 is fixedly connected to the inner wall of the box body, and the first connection seat 210 is arranged opposite to the second connection seat 310. A through hole is arranged on the first connection seat 210, and the threaded shaft 220 passes through the through hole and is rotatably arranged in the through hole. Among them, one end of the ring 230 is rotatably arranged in the through hole. The first worm gear 240 is fixedly connected along the outer circumferential side wall of the ring 230.

[0041] The horizontal adjustment assembly 200 also includes a second worm 330 and two first mounting seats 250, and the two first mounting seats 250 are respectively fixedly connected to the side walls of the first connecting seat 210 facing away from the box body. The two ends of the first worm 260 are respectively rotatably arranged on the two first mounting seats 250, and the first worm 260 is also arranged vertically. The first worm 260 is meshed with the first worm gear 240. The lower end of the first worm 260 is fixedly connected to the first rotating disk 270, and the first worm 260 is driven to rotate by rotating the first rotating disk 270.

[0042] When it is necessary to adjust the cutting shaft 120 to move in the horizontal direction, the first turntable 270 is rotated, and the first turntable 270 drives the first worm 260 to rotate. The rotating first worm 260 engages with the first worm gear 240, thereby driving the ring 230 to rotate, and the ring 230 engages with the threaded shaft 220.

[0043] During this process, the rotation between the positioning shaft 370 and the second worm gear 350 is restricted by the positioning pin, and the second worm gear 350 and the second worm 330 are self-locked. As the first worm gear teeth 240 rotate, the threaded shaft 220 moves toward the inside of the ring 230 along the axial direction of the wire cutting shaft 120, thereby realizing the horizontal adjustment of the wire cutting shaft 120.

[0044] Example 2

[0045] The difference between this embodiment and embodiment 1 is that the level adjustment component is different.

[0046] Reference Figure 6 As shown, the level adjustment assembly 200 includes a threaded shaft 220 and a ring 230. The threaded shaft 220 is coaxially fixedly connected to the end of the cutting shaft 120 away from the positioning shaft 370. The ring 230 is sleeved on the threaded shaft 220, and the ring 230 and the threaded shaft 220 are meshed with each other.

[0047] In the embodiment of the present application, only the ring 230 and the threaded shaft 220 are meshed with each other, so that the threaded shaft 220 is driven to move in the horizontal direction by rotating the ring 230. In this process, different driving sources can be used to drive the ring 230 to rotate, and different limiting devices can be used to limit and fix the ring 230.

[0048] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
