Description

Technical Field

[0001] The utility model relates to the technical field of cigarette filter rod manufacturing, in particular to a paper belt stabilizing device for a paper splicer. Background Art

[0002] The YF71 paper splicer is an important part of the filter rod production process. Its main function is to automatically and continuously provide the forming paper required for the forming unit to produce filter rods, reducing the workload and labor intensity of manual loading during the filter rod production process. When the equipment is running, the turning device installs the new paper on the paper cart on the lower part of the circulation disk, rotates 180°, and the paper is taken and threaded by the paper taking device. When the old paper is used to a certain diameter, the new paper begins to accelerate under the action of the acceleration device. When the speeds of the two paper are consistent, the tape on the splicing device sticks the paper tapes of the two paper together. The cutting device cuts off the rear end of the old paper and the front end of the new paper at the same time, and they are recycled by the acceleration device and the old paper recycling device respectively. The equipment continues to run. When the new paper is used to a certain diameter, the turning device installs the new paper on the lower part of the circulation disk again, repeating the steps of rotation, taking paper, threading paper, and splicing, so as to achieve the purpose of continuous supply of forming paper.

[0003] There are four paper guide rollers at the bottom of the circulating tray of the YF71 paper splicer, including a pull rod paper guide roller, two circulating tray paper guide rollers and a swing rod paper guide roller. The paper guide rollers support and assist the paper tape to run and reduce the friction of the paper tape. The paper guide rollers are all cylindrical and have no retaining ring design, which cannot limit the running track of the paper tape on the paper guide rollers. Due to the low loading accuracy of the YF71 paper reel machine, the unstable brake mechanism, and the large vibration when the paper reel is spliced, the paper tape of the old paper reel will move on the paper guide roller before or during splicing, and the new and old paper tapes after splicing cannot be aligned. The product quality during the splicing period fluctuates greatly, and even causes equipment shutdown, paper tape breakage, and wire bundle winding roller failure, which will reduce the production efficiency of filter rods and increase the consumption of raw and auxiliary materials.

[0035] The utility model provides a paper tape stabilizing device for a paper splicer, wherein the eccentric connecting hole 110 of the connecting shaft 100 adopts an eccentric design, and the connecting shaft 100 is connected to the swing arm through the eccentric connecting hole 110, and the tension of the support rod 200 on the paper tape 10 can be adjusted according to the running trajectory of the paper tape 10 and the size of the pulling force, so as to achieve the effect of eliminating or weakening the movement of the paper tape 10, and the second retaining ring 400 and the first retaining ring 300 are arranged on the support rod 200 at intervals, and during the movement of the paper tape 10, the swing arm drives the connecting shaft 100 to extend, and the connecting shaft 100 drives the support rod 200 to extend to support the paper tape 10, and the paper tape 10 falls into the restricted area between the first retaining ring 300 and the second retaining ring 400, so as to prevent the paper tape 10 from lateral movement. During installation and adjustment, loosen the first fastening screw 320 and the second fastening screw 420, so that the first retaining ring 300 and the second retaining ring 400 can easily move along the axial direction of the support rod 200, and move the first retaining ring 300 and the second retaining ring 400 close to the two sides of the paper tape 10 respectively.

[0036] It should be noted that the swing rod is a relatively conventional swinging member and is not the object to be protected by the present utility model, so it will not be described in detail here.

[0037] In some embodiments, a slot hole 120 is provided along the axis of the end of the connecting shaft 100 away from the eccentric connecting hole 110, and a bearing 121 is embedded in the slot hole 120. The inner ring of the bearing 121 is fixedly sleeved on the end of the support rod 200. Through the above structure, the support rod 200 can rotate relative to the connecting shaft 100, so that the paper tape 10 passes through the support rod 200 more smoothly. An internal thread is provided in the eccentric connecting hole 110, and a round hole is provided on the swing rod that is aligned with the eccentric connecting hole 110. The bolt passes through the round hole and is screwed with the internal thread to realize a detachable connection between the swing rod and the connecting shaft 100, which is convenient for adjusting the connecting shaft 100, so as to adjust the tension of the support rod 200 on the paper tape 10 according to the running track of the paper tape 10 and the pulling force.

[0038] In some embodiments, a first chamfer 330 is provided on one side edge of the first baffle ring 300 close to the second baffle ring 400, and the first chamfer 330 plays a certain guiding role on the paper tape 10, so that the paper tape 10 can smoothly fall between the first baffle ring 300 and the second baffle ring 400. Similarly, a second chamfer 430 is provided on one side edge of the second baffle ring 400 close to the first baffle ring 300, and the second chamfer 430 plays a certain guiding role on the paper tape 10, so that the paper tape 10 can smoothly fall between the first baffle ring 300 and the second baffle ring 400. Specifically, the diameter of the first baffle ring 300 is the same as the diameter of the second baffle ring 400, and the thickness of the first baffle ring 300 is the same as the thickness of the second baffle ring 400, so as to ensure that the first baffle ring 300 and the second baffle ring 400 have the same running track restrictions on the paper tape 10.

[0039] In some embodiments, the connecting shaft 100, the support rod 200, the first retaining ring 300 and the second retaining ring 400 are all made of steel. For example, the connecting shaft 100, the support rod 200, the first retaining ring 300 and the second retaining ring 400 are all made of 45# steel, which has high hardness and wear resistance.

[0040] The paper tape stabilizing device for the paper splicer provided by the utility model can limit the running track of the paper tape 10, and prevent the paper tape 10 from moving on the paper guide roller 20, resulting in uneven force on the paper tape 10 and breaking. In addition, when splicing paper coils, the paper tape stabilizing device for the paper splicer can reduce or eliminate the movement of the paper tape 10 caused by equipment factors such as low loading accuracy, unstable brake mechanism, and large vibration during splicing, thereby ensuring good splicing quality of paper coils, ensuring the continuity of paper tape 10 supply, the stability of product quality, and reducing the waste of raw and auxiliary materials caused by poor or failed splicing of paper coils.

[0041] The eccentric connecting hole 110 on the connecting shaft 100 adopts an eccentric design and is fixed to the swing rod by bolts. The tension of the paper tape 10 can be adjusted according to the running trajectory of the paper tape 10 and the size of the pulling force, so as to achieve the effect of eliminating or reducing the movement. When the circulating disk rotates, the paper tape 10 follows the movement, and the paper tape 10 is supported by the support rod 200. The first chamfer 330 and the second chamfer 430 can effectively ensure that the paper tape 10 with a large movement amplitude smoothly falls into the restricted area between the first retaining ring 300 and the second retaining ring 400, so as to avoid the paper tape 10 being stuck in the first retaining ring The retaining ring 300 or the second retaining ring 400 is pulled off, causing the equipment to shut down abnormally; the first retaining ring 300 is fixed by the first fastening screw 320, and the second retaining ring 400 is fixed by the second fastening screw 420. The first retaining ring 300 and the second retaining ring 400 can be adjusted according to the position of the paper tape 10 to ensure that the paper tape 10 just contacts the first retaining ring 300 and the second retaining ring 400. The first retaining ring 300 and the second retaining ring 400 can limit the running trajectory of the paper tape 10 while also preventing the paper tape 10 from being pulled off due to uneven force.

[0042] The paper tape stabilizing device for the paper splicer has a simple structure, low manufacturing cost, convenient installation, strong practicality, and can effectively reduce or even eliminate the phenomenon of paper tape 10 moving, provide stable splicing conditions for paper coil splicing, and ensure the quality of paper coil splicing. After application, it can effectively improve the continuity and stability of paper coil supply, avoid product quality fluctuations caused by poor paper coil splicing, and also improve the effective operation rate of filter rod production and reduce the waste of raw and auxiliary materials caused by failed paper coil splicing.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
