Description

Technical Field

[0001] The utility model relates to an auxiliary tool for cigarette production equipment, in particular to a tool used for a filter rod cutting wheel of a cigarette rolling and splicing unit. Background Art

[0002] The existing PROTOS-M5 filter rod cutting process of the winding machine is as follows: the alloy steel circular blade cuts into the cutting slit of the filter tip cutting wheel, and the motor drives the circular blade to rotate at high speed, cutting the filter rod adsorbed in the wheel groove of the cutting wheel into two sections for use when connecting the filter tip downstream. Since the filter rod is formed by a combination of tow, forming paper, glycerin, center line glue, and overlap glue, the cutting process will produce filter rod powder and glue scale, which will adhere to both sides of the filter tip cutting wheel slit. The circular blade will also be stained with glue scale, increasing the load of the circular blade operation, resulting in a lag failure of the circular blade of the filter rod connecting machine, causing equipment shutdown. Therefore, it is necessary to regularly clean the knife gap of the filter rod slitting wheel. The filter rod slitting wheel includes a hub and an adsorption groove wheel body fixedly mounted on the hub. The adsorption groove wheel body is composed of two half-wheel bodies distributed along the axial direction. The gap between the two half-wheel bodies forms a knife gap. Before cleaning, the adsorption groove wheel body needs to be removed from the hub to separate the two half-wheel bodies, and then the dirt at the knife gap can be cleaned.

[0003] Since the adsorption groove wheel body and the wheel hub fit tightly, angle steel or flat iron is generally used to press against the two ends of the adsorption groove wheel body, and then a long copper rod or aluminum rod angle steel or flat iron is used. It needs to be knocked repeatedly many times to remove the adsorption groove wheel body from the wheel hub. If too much force is used during the knocking, both ends of the adsorption groove wheel body will be damaged. It can only be knocked slowly to separate the adsorption groove wheel body from the wheel hub little by little. The whole process is time-consuming and laborious, and there are safety hazards. Even if it is knocked lightly, the adsorption groove wheel body has been damaged. After it is assembled again, radial runout is likely to occur during the operation of the machine, thereby damaging the transmission shaft of the filter rod slitting wheel and other transmission components. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provides a tooling for a filter rod slitting wheel of a roll-joining unit, so as to realize convenient, time-saving, labor-saving and non-destructive disassembly of an adsorption groove wheel body.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] The utility model provides a tooling for a filter rod slitting wheel of a rolling machine unit, which has the advantages of a limit ring against the bottom end of an adsorption groove wheel body, a cross brace against the top end of a wheel hub, a bottom end of a push rod against the cross brace, and a rotation of the push rod. Since the bottom end of the push rod is against the cross brace, the push rod can only rotate but not move axially. Under the cooperation of the threads of the push rod and the threaded hole of the bracket, the bracket can be driven to move upward, and the pulling force is transmitted to the adsorption groove wheel body through the pulling claws and the limit ring, so that the adsorption groove wheel body is pulled upward from the wheel hub. The whole operation process is convenient, fast, time-saving and labor-saving, and will not cause damage to the adsorption groove wheel body. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following is a detailed description of an embodiment of the utility model. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0018] See also Figure 1 to Figure 2 The present embodiment discloses a tooling for a filter rod slitting wheel of a roll-to-roll unit. The filter rod slitting wheel comprises a hub 1 and an adsorption groove wheel body 2 fixedly mounted on the hub 1. The tooling comprises a bracket 3, a limiting collar 4, a push rod 5 and a cross brace 6. The bracket 3 is provided with a plurality of connecting rods 7 distributed along the circumference. In the present embodiment, the bracket 3 is provided with three connecting rods 7 evenly distributed along the circumference. Each connecting rod 7 extends radially outwardly along the bracket 3. A pull claw 8 is movably mounted on each connecting rod 7. A plug hole is provided at the upper end of the pull claw 8. The pull claw 8 is mounted on the connecting rod 7 through the plug hole. The claw 8 extends along the axial direction of the bracket 3, and the claw 8 can slide along the length direction of the connecting rod 7. The bottom of the claw 8 is provided with a hook block 9 protruding inward, and the hook blocks 9 at the bottom of the multiple claws 8 are used to hook the limiting collar 4. The center of the bracket 3 has a threaded hole, and the push rod 5 is threadedly connected to the threaded hole of the bracket 3. The bottom of the push rod 5 extends out from under the bracket 3 and connects to the cross brace 6. The cross brace 6 is located between the multiple claws 8. The center of the top of the cross brace 6 has a positioning groove, and the bottom end of the push rod 5 abuts against the positioning groove of the cross brace 6. The top of the push rod 5 extends above the bracket 3 and is provided with an external hexagonal operating head 10, which is convenient for it to cooperate with a wrench for rotation operation.

[0019] The two end faces of the cross brace 6 can be designed as arc surfaces. The length of the cross brace 6 is larger than the inner diameter of the hub 1 and smaller than the inner diameter of the adsorption groove wheel body 2, so that it will not interfere with the process of the adsorption groove wheel body 2 coming out.

[0020] When it is necessary to clean the knife seam of the filter rod slitting wheel, first, place the cross brace 6 against the upper end of the wheel hub 1, place the limiting collar 4 against the lower end of the adsorption groove wheel body 2, place the bottom of the push rod 5 against the positioning groove in the center of the cross brace 6, hang the upper parts of the three claws 8 on the three connecting rods 7 of the bracket 3 respectively, and make the hook blocks 9 at the bottom of the three claws 8 hook the bottom surface of the limiting collar 4. Then, put an inner hexagonal wrench on the outer hexagonal operating head 10 at the top of the push rod 5, turn the inner hexagonal wrench, and drive the push rod 5 to rotate. Due to the obstruction of the cross brace 6, the push rod 5 will not move axially but only rotate. The rotating push rod 5 drives the bracket 3 to move upward, and transmits the pulling force to the adsorption groove wheel body 2 through the claws 8 and the limiting collar 4, so that the adsorption groove wheel body 2 is pulled upward from the wheel hub 1. After the adsorption groove wheel body 2 is pulled out, its two half-wheel bodies are naturally separated, and the dirt at the knife seam can be easily cleaned. The entire operation process is convenient, fast, time-saving and labor-saving, and will not cause damage to the adsorption groove wheel body 2, thereby ensuring the reliability of the filter rod cutting wheel when it is installed and used again.

[0021] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
