Description

Technical Field

[0001] The utility model relates to the technical field of drum winding machines, in particular to a firecracker drum winding machine. Background Art

[0002] A paper roll machine is a machine used to roll sheet materials into a tube, such as rolling metal sheets into metal tubes, or paper into paper rolls. When rolling paper into paper rolls such as straws and firecrackers, a small paper roll machine is used to put the paper roll on the roller rod on the bracket of the paper roll machine. The roller rod is an extremely thin round rod. As the paper roll machine runs, the vibration of the machine during operation will make the paper roll unable to be coaxial with the roller rod, which can easily cause the paper roll to become loose when unwinding, affecting the paper roll, resulting in the rolled paper roll being relatively loose and of poor quality.

DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0026] Please refer to 1-6, a firecracker reel, comprising: a reel 01, a bracket 02 is mounted on the reel 01, a mounting plate 1 is fixedly connected to the bracket 02, a rotating shaft 2 is rotatably mounted inside the mounting plate 1, a plurality of sliding sleeves 3 are slidably sleeved outside the rotating shaft 2, the sliding sleeves 3 are connected to the support plate 4 via a connecting rod 5, one end of the connecting rod 5 is rotatably mounted on the sliding sleeve 3, and the other end of the connecting rod 5 is rotatably mounted on the support plate 4, a limiting disk 9 is provided on one side of the mounting plate 1, and one end of the support plate 4 is slidably mounted. It is placed on the limit plate 9. When the sliding sleeve 3 slides on the rotating shaft 2, the support plate 4 slides radially on the limit plate 9. The end of the rotating shaft 2 away from the limit plate 9 is connected with a screw sleeve 8 through an external thread. The outer surface of the screw sleeve 8 is connected with an anti-slip sleeve 81 to increase the friction between the hand and the screw sleeve 8. The sliding sleeve 3 and the limit plate 9 are connected by a second spring 6. One end of the second spring 6 is fixedly connected to the limit plate 9, and the other end of the second spring 6 is fixedly connected to the sliding sleeve 3. The second spring 6 is sleeved outside the rotating shaft 2.

[0027] Specifically, refer to Figure 2 、 Figure 4 as well as Figure 5First, put the roll in the middle of the paper roll on the outside of the support plate 4, and then screw the screw sleeve 8 to make the screw sleeve 8 slide to the right on the rotating shaft 2, thereby squeezing the sliding sleeve 3. After overcoming the elastic force of the second spring 6, the sliding sleeve 3 slides to the right on the rotating shaft 2. Since one end of the support plate 4 is limited on the limiting disk 9, it can slide in the radial direction of the limiting disk 9, so that the support plate 4 slides on the rotating shaft 2 with the sliding sleeve 3, and the connecting rod 5 rotates accordingly, causing the support plate 4 to slide in the radial direction of the limiting disk 9, thereby achieving the purpose of squeezing the paper roll with multiple support plates 4.

[0028] The utility model puts the paper roll on the outside of multiple support plates 4 and drives the sliding sleeve 3 to slide on the rotating shaft 2, so that the multiple support plates 4 squeeze the paper roll, so that the paper roll is fixed outside the multiple support plates 4, so that the reel and the rotating shaft 2 are always coaxial and rotate synchronously, avoiding the situation where the paper roll becomes loose when the paper is released, and improving the quality of the reel rolled out by the reel machine 01.

[0029] Furthermore, the limiting plate 9 is provided with a second sliding groove 91 and further includes a screw 7 , which passes through the second sliding groove 91 and is threadedly connected to the support plate 4 .

[0030] Specifically, the support plate 4 is limited by using screws 7. When the screw sleeve 8 squeezes the sliding sleeve 3, the support plate 4 and the limit plate 9 are locked together by the screws 7, so that the support plate 4 cannot move in the left and right directions, which facilitates the disassembly and installation of the equipment and reduces production costs and subsequent maintenance costs.

[0031] Furthermore, the outer side of the support plate 4 is arc-shaped, and a plurality of rubber strips are fixedly connected to the outer arc-shaped surface of the support plate 4 .

[0032] Specifically, the outer side of the support plate 4 is opened into an arc shape in order to better adapt to the paper tube in the paper roll. Multiple rubber strips are glued to the outer side of the support plate 4 to make the paper roll and the multiple support plates 4 more stable.

[0033] Furthermore, the mounting plate 1 and the rotating shaft 2 are connected via a bearing 10 .

[0034] Specifically, refer to Figure 3 The outer ring of the bearing 10 is embedded in the mounting plate 1, and the inner ring of the bearing 10 is fixedly sleeved on the outside of the rotating shaft 2, so that the rotating shaft 2 can rotate freely relative to the mounting plate 1.

[0035] Furthermore, a first sliding groove 021 is provided on the bracket 02, and a partition 022 is fixedly connected in the first sliding groove 021. A slider 025 is slidably arranged in the first sliding groove 021, and the slider 025 and the partition 022 are connected by a first spring 024. One end of the first spring 024 is fixedly connected to the slider 025, and the other end of the first spring 024 is fixedly connected to the partition 022. A rotating rod 026 is fixedly connected to the slider 025, and a roller 027 is movably sleeved on the outside of the rotating rod 026. A guide rod 023 is fixedly connected to the slider 025, and the first spring 024 is sleeved on the outside of the guide rod 023. The end of the guide rod 023 away from the slider 025 passes through the partition 022.

[0036] Specifically, refer to Figures 1 to 6 The paper roll assembly 03 includes a mounting plate 1, a rotating shaft 2, a sliding sleeve 3, a support plate 4, a connecting rod 5, a second spring 6, a screw 7, a screw sleeve 8, a limit plate 9, and a bearing 10. After the paper roll is put on the outside of the paper roll assembly 03, the outer side of the paper roll squeezes the roller 027, so that the slider 025 overcomes the elastic force of the first spring 024 and slides along the direction of the first slide groove 021. As the reel machine 01 works, the outer diameter of the paper roll gradually decreases, and the roller 027 always rests on the outer surface of the paper roll. When the paper roll is lifted to unwind, the paper can be fed into the reel machine 01 evenly and accurately.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
