Description

Technical Field

[0001] The utility model belongs to the technical field, and in particular relates to a tool for fine-tuning the stroke of a trumpet mouth of a ZJ17 crimping machine unit. Background Art

[0002] During the tobacco rod cutting process, the bell mouth mechanism is mainly used to provide necessary support for tobacco rod cutting. When in the cutting position, the speed of the bell mouth mechanism's forward movement should be consistent with the speed of the tobacco rod. The bell mouth mechanism is mainly driven by a crank and a connecting rod to drive the bell mouth support to do reciprocating motion. The vibrating plate is fastened together with the left end of the connecting rod, which plays a supporting role and enables the crank-connecting rod mechanism to return quickly when passing the front and rear stroke ends. The stroke of the bell mouth matched with each length of cigarette is different. The eccentricity of the crank can be adjusted, and the scale value on the crank is for coarse adjustment of the stroke of the bell mouth support. During the equipment maintenance and adjustment process, when the maintenance worker needs to adjust the stroke of the bell mouth, he generally uses the dial to coarsely adjust the stroke of the bell mouth support. Since the precise stroke of the bell mouth is required to be controlled within the range of ±0.03mm, such as Figure 2 As shown, when the stroke of the trumpet is adjusted to be too small, the blade 7 will produce a horizontal displacement relative to the inlet trumpet during the cutting process, and move toward the outlet trumpet, causing a slight change in the supporting position of the tobacco rod; when the stroke of the trumpet is adjusted too small, the blade 7 will collide with the outlet trumpet, causing accelerated wear of the blade 7 and the outlet trumpet, and easily damaging the blade 7, resulting in quality accidents; therefore, after the coarse adjustment of the stroke of the trumpet, it is necessary to fine-tune it, and the current fine-tuning method is to use a hook wrench or insert a long pin into the edge hole of the crank head 1. When turning the crank head 1, either the force is too small, and the crank head 1 does not move; or the force is too large, causing the crank head 1 to rotate excessively, making it difficult to gradually approach the measured value to the required value. Due to the lack of a suitable fine-tuning tool, sometimes a hammer is used to tap the long pin on the crank head 1 to cause it to rotate slightly. Obviously, this does not meet the maintenance requirements. Therefore, it is necessary to make improvements to the above-mentioned problems. Utility Model Content

[0019] ZJ17 coiling machine bell mouth stroke fine adjustment tool, such as Figure 1As shown, it includes an adjusting pin 2 inserted into the crank head 1 and a fixing block 4 fixed on the crank arm 3 and located on the left side of the adjusting pin 2, the fixing block 4 is in a V-shaped structure (similar to an L-shape) with different lengths on both sides, and the V-shaped mouth of the fixing block 4 is arranged upward, a positioning groove is formed on the right end plate surface of the fixing block 4 and an adjusting knob 5 is arranged in the positioning groove, a waist-shaped hole is formed on the left side wall of the right end plate of the fixing block 4, which is connected with the positioning groove and passes through the right side wall of the right end plate, and an adjusting screw 6 threadedly connected to the adjusting knob 5 passes through the waist-shaped hole and is fixedly connected to the adjusting pin 2, and the distance between the adjusting pin 2 rotating clockwise or counterclockwise and the fixing block 4 is controlled by rotating the adjusting knob 5, so as to realize the clockwise or counterclockwise rotation of the crank head. 1 fine-tuning; wherein, the fixing block 4 and the adjusting pin 2 are made of 45# steel, the adjusting screw 6 is selected from a 0.8 pitch, M5×40mm hexagonal screw, and a waist-shaped hole connected to the positioning groove is provided on the fixing block 4. On the one hand, it is used to position the adjusting screw 6, that is, the big head end of the adjusting screw 6 is always located outside the waist-shaped hole, and on the other hand, it provides the necessary movement margin for the adjusting screw 6, thereby ensuring the smooth adjustment of the adjusting pin 2. In the above structure, the adjusting knob 5 provided in the fixing block 4 is used to adjust the extension length of the adjusting screw 6 fixedly connected to the adjusting pin 2, so as to realize the precise fine-tuning of the trumpet mouth stroke, thereby solving the problem that the traditional adjustment method is difficult and has poor accuracy in fine-tuning the trumpet mouth stroke.

[0020] The fixed connection structure between the adjusting pin 2 and the adjusting screw 6 is specifically as follows: a threaded hole is formed on the rod wall of the protruding end of the adjusting pin 2, and the protruding end of the adjusting screw 6 is adapted to be connected with the threaded hole on the adjusting pin 2.

[0021] The installation structure of the fixed block 4 on the crank arm 3 utilizes the screw holes and screws on the crank arm 3 for installing the counterweight block. When installing the fixed block 4, the counterweight block is removed, and then the left end plate of the fixed block 4 is installed on the crank arm 3 by screws. This installation structure does not require any changes to the equipment, thereby protecting the original accuracy.

[0022] Among them, the outer wall in the circumferential direction of the adjustment knob 5 is provided with a scale for accurately controlling the adjustment progress of the horn mouth stroke; specifically, the adjustment knob 5 is marked with six scales, each 60° is a scale, and the adjustment progress of each scale is about 0.13mm. For each rotation of the adjustment knob 5, the adjustment progress of each rotation of the adjustment knob 5 is 0.8mm.

[0023] When it is necessary to adjust the stroke of the horn mouth, first make a coarse adjustment on the dial on the crank head 1, loosen the six fastening screws on the crank head 1, turn the crank head 1 to adjust the required cigarette length with reference to the "0" point of the crank arm, and slightly tighten the fastening screws after coarse adjustment; insert the pin into the pin hole of the horn mouth support, turn the machine turning handwheel, and use a micrometer to measure the distance between the extreme positions of the left and right movement of the pin. If the measured distance does not meet the requirements, fine-tune it until it meets the fine-tuning stroke.

[0024] Remove the counterweight on the crank arm 3, and use the two screws to tighten the counterweight to install the fixed block 4 of the bellmouth stroke fine-tuning tool on the crank arm 3. At the same time, insert the adjusting pin 2 into the hole of the crank head 1 closest to the fixed block 4. After the fine-tuning tool is installed, it should not exceed the root arc of the turning gear on the crank arm 3.

[0025] like Figure 2 As shown, before rotating the adjusting screw 6, make the reading of the micrometer 8 the maximum value, and then rotate the adjusting screw 6 to make the change in the reading of the micrometer 8 half of the difference between the measured value and the actual required value. If the measured stroke value is too large, rotate the adjusting screw 6 clockwise to drive the crank head 1 to rotate slightly counterclockwise to reduce the stroke; if the measured stroke value is too small, rotate the adjusting screw 6 counterclockwise to push the adjusting pin 2 to drive the crank head 1 to rotate clockwise relative to the crank arm 3 to increase the stroke of the bell mouth; after the adjustment is completed, tighten the six fastening screws that fasten the crank head 1, remove the bell mouth stroke fine-tuning tool, and reinstall the counterweight.

[0026] By adopting the technical solution, the trumpet mouth stroke fine-tuning tool is easy to assemble and disassemble, and the adjustment is accurate and reliable. By using it, the trumpet mouth stroke can be adjusted to an accuracy of ±0.01mm in 5 minutes. Compared with the original 20 to 30 minutes required to meet the working requirements without using the trumpet mouth stroke fine-tuning tool, the adjustment time is reduced. Since the adjustment accuracy is improved, the quality of the cigarette incision is improved, the wear of the tobacco cutting blade 7 and the trumpet mouth is reduced, the service life of the parts is greatly improved, and it is suitable for micro-adjustments, and can realize a small rotation of the crank head relative to the crank arm 3, and can be widely used.
