Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical maintenance of tobacco leaf cutting equipment, and in particular relates to a device for quickly adjusting the parallelism of a pusher half nut of a cutting machine. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] The slitting process is the only process in the slitting production line that changes the properties of tobacco materials. The uniformity of the slitting width directly affects the slitting quality (slitting machine process indicators: slitting capacity, slitting width accuracy, slitting qualified rate), and the parallelism of the pusher half nut directly determines the uniformity of the slitting width. Therefore, it is necessary to regularly check and adjust each blade pusher device to ensure that the parallelism error of the left and right pusher half nuts is controlled within 0.07mm. At present, there are two commonly used adjustment methods: one is to disengage the two feed worm shaft couplings for adjustment, and the other is to disengage the worm gear / worm gear on one side for adjustment; both methods require the use of a depth vernier caliper to measure the height difference of the left and right pusher half nuts, and convert it into the number of turns / teeth required on one side. During the operation, it is affected by many factors such as measurement error, manual calculation error, and operation error. The success rate of one adjustment is low, and repeated measurement and adjustment are often required. The adjustment efficiency is low and it takes a long time. Utility Model Content

[0030] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0031] Example 1

[0032] In a typical implementation of the present invention, Figure 1-3 As shown, a device for quickly adjusting the parallelism of a half-nut of a push knife of a wire cutting machine is provided, comprising a fixed guide rail base 1 and an adjustable reference slider 2, wherein the fixed guide rail base 1 comprises a rod 101 and a plate 102, wherein the rod 101 and the plate 102 are vertically arranged so that the fixed guide rail base 1 is in a T-shaped structure; a groove 201 is arranged on the adjustable reference slider 2, and the shape of the groove 201 matches the shape of the plate 102, and the adjustable reference slider 2 can slide up and down along the plate 102.

[0033] like Figure 2 As shown, the rod 101 is a rectangular parallelepiped structure, the width of the rod 101 is greater than the thickness of the plate 102, and the rod 101 and the plate 102 are set as an integral structure, wherein the portion of the rod 101 that is wider than the thickness of the plate 102 serves as the first positioning working surface 103, and the inner side surface of the plate serves as the second positioning working surface 104, the first positioning working surface 103 and the second positioning working surface 104 are perpendicular, and the second positioning working surface 104 serves as the inner side surface. Figure 6 and Figure 7 The first positioning working surface 103 is in contact with the guide wire strip mounting surface A on the knife roller body 18, and the second positioning working surface 104 is in contact with the blade mounting surface B on the guide roller body.

[0034] like Figure 3As shown, the adjustable reference slider 2 is a rectangular parallelepiped structure, and the groove 201 on the adjustable reference slider 2 is a dovetail groove shape. The groove 201 passes through the upper and lower surfaces of the adjustable reference slider and is opened toward the plate. The dovetail groove cooperates with the plate with a trapezoidal cross section to prevent the adjustable reference slider from falling off when sliding on the plate 102. The bottom surface of the adjustable reference slider 2 serves as a working reference surface 202, and the working reference surface 202 fits with the step surface of the push blade half nut C. The surface where the opening of the adjustable reference slider is located is flush with the surface of the plate, so that the inner side surface of the adjustable reference surface fits with the inner side surface of the plate and the blade installation plane, so as to quickly adjust the parallelism of the push blade half nut.

[0035] In this embodiment, the width of the plate is smaller than the distance between the left push blade half nut and the right push blade half nut to prevent the plate from hindering the adjustment of the left push blade half nut and the right push blade half nut.

[0036] The feeding principle of the existing wire cutting machine is as follows Figure 4 and Figure 5 As shown, the special handle rotates the manual feed lever 3, and the power is transmitted to the right feed worm shaft 6 through a pair of bevel gear motion pairs. The right feed worm shaft 6 rotates to drive the right feed worm wheel 7 meshing with it to rotate. The right feed worm wheel 7 transmits the power to the right pusher screw 13 through a key connection. The right pusher screw 13 rotates to drive the right pusher half nut 14 that matches it to move up and down linearly; the left feed worm shaft 9 is connected to the right feed worm shaft 6 through a coupling 8, so that the pusher half nuts on the left and right sides can move synchronously, and jointly push the blade upward to realize manual feed. The parallelism of the pusher half nuts on the left and right sides directly determines the uniformity of the wire cutting width, so it is necessary to regularly check and adjust each blade pusher device to ensure that the parallelism error of the left and right pusher half nuts is controlled within 0.07mm. By disengaging the coupling 6, independent adjustment on one side can be achieved, thereby realizing the parallelism adjustment of the pusher half nuts on the left and right sides.

[0037] The steps of adjusting the parallelism of the half nut of the push blade of the wire cutting machine using the device provided in this embodiment are as follows:

[0038] Part 1: Preparation before adjustment.

[0039] 1. Remove the knife pressing plate bolts, and take off the knife pressing plate and blade;

[0040] 2. Remove the wire guide screw and take out the wire guide;

[0041] 3. Remove the dust cover screws and take off the dust cover;

[0042] 4. Loosen the set screws of the coupling between the left and right feed worm shafts to disconnect the connection between the two shafts;

[0043] 5. Move the right push knife half nut down one pitch.

[0044] Part 2: Parallelism adjustment.

[0045] 1. Pre-install the adjustable reference slider on the fixed guide rail base;

[0046] 2. Install the fixed guide rail base so that the inner surface of the rod fits with the guide wire installation surface on the knife roller body, and the inner surface of the plate fits with the blade installation surface on the knife roller body. Use the two middle magnets on the blade installation surface on the knife roller body to attract and fix the L-shaped fixed guide rail base. In this process, keep the adjustable reference slider at a higher position;

[0047] 3. Manually adjust the upper and lower positions of the adjustable reference slider so that the lower surface of the adjustable reference slider coincides with the step surface of the left pusher half nut, thereby fixing the upper and lower positions of the adjustable reference slider;

[0048] 4. With the lower surface of the adjustable reference slider as the reference, shake the manual feed device bevel gear to move the right push knife half nut upward until the push knife step surface of the right push knife half nut coincides with the bottom surface of the right end of the adjustable reference slider;

[0049] 5. Install the coupling, restore the connection between the left and right feed worm shafts, and screw in the set screws;

[0050] 6. Remove the L-shaped fixed guide rail base and the adjustable reference slider.

[0051] Part III: Recovery after adjustment.
