Description

Technical Field

[0001] The utility model relates to the technical field of paper stick cotton swab preparation devices, and more specifically, to a paper stick cotton swab preparation device. Background Art

[0002] In the existing paper stick cotton swab preparation technology, the degree of automation of the production process still needs to be improved. Most of the existing technologies still rely on manual feeding methods. Operators need to arrange the paper sticks one by one and then complete the preparation of cotton swabs through a conveyor belt. This traditional method is not only time-consuming and laborious, but also has low efficiency, causing unnecessary waste of production efficiency and labor resources. In the context of the increasing labor costs, this production method has an adverse economic impact.

[0003] In addition, when preparing paper sticks in the existing technology, adhesives are usually used to bond pulp or paper into paper sticks. In order to accelerate the drying process of the adhesive, heating wires are often used on the production line. However, after long-term high-intensity use, the heating wires may age or be damaged and need to be replaced or maintained. In the existing technology, the heating wires are usually installed in a special installation bin, and the installation and disassembly operations of this installation bin are usually cumbersome. Operators need to spend a lot of time on disassembly, replacement and reinstallation, which not only increases the maintenance cost, but also affects the continuity and efficiency of production.

[0004] To solve these problems, some advanced production equipment adopts devices with quick installation and disassembly, which are designed to simplify the operation process of the heating wire installation bin and improve the maintenance efficiency. However, the structural design of these devices is relatively simple and the mechanism is not perfect. In actual applications, these devices may become structurally loose due to equipment vibration, temperature changes or other external factors, resulting in a decrease in equipment stability and even potential production accidents. This problem of low structural stability not only affects the safety and reliability of production, but also increases the maintenance frequency and cost of the equipment.

The limiting mechanism includes a rotating sleeve 14, a clearance hole 15, a push rod 16, a sliding sleeve 17, a conical spring 18, a limiting rod 19 and a limiting groove 20. The rotating sleeve 14 is sleeved on the outside of the splicing sleeve 8, the clearance hole 15 is opened on the rotating sleeve 14, the push rod 16 is connected to one side of the sliding sleeve 17, and the sliding sleeve 17 is sleeved on the outside of the splicing sleeve 8. One end of the limiting rod 19 is connected to the side wall of the rotating sleeve 7 through the conical spring 18, and the other end of the limiting rod 19 is inserted into the limiting groove 20. A plurality of limiting grooves 20 are opened on the outside of the splicing sleeve 8.

[0034] A push spring 21 is sleeved on the outer side of the push rod 16 , one end of the push spring 21 is in contact connection with the rotating sleeve 14 , and a spring 22 is connected to one side of the clamping block 13 .

[0036] An anti-slip strip 25 is connected to the outer sides of the rotating sleeve 14 and the rotating sleeve 7 .

[0037] In this embodiment, when the resistance wire 28 needs to be inspected or maintained and replaced, the rotating sleeve 14 is first rotated to make the rotating sleeve 14 drive the clearance hole 15 to move. When the clearance hole 15 moves to the position corresponding to the top rod 16, the sliding sleeve 17 is pushed, and the sliding sleeve 17 drives the top rod 16 to pass through the clearance hole 15. Then the outer side of the limiting rod 19 loses the limit of the limiting sleeve, and then the rotating sleeve 7 is rotated, and the rotating sleeve 7 drives the limiting rod 19 to move. Due to the rounded structure design at the end of the limiting rod 19 and the edge of the limiting groove 20, when the side wall of the limiting groove 20 squeezes one end of the limiting rod 19, then the limiting rod 19 and one end of the limiting rod 19 will slide out of the limiting groove 20, and at the same time, the limiting rod 19 will drive The conical spring 18 is stretched, and then the rotating sleeve 7 drives the adapter block 9 to move. Due to the special structural design of the adapter block 9, when the adapter block 9 moves with the rotating sleeve 7, the adapter block 9 pushes the matching block 10 to move, and then the matching block 10 drives the clamping block 13 to slide out of the splicing groove 11, and the clamping block 13 squeezes the spring 22 set on one side. When the rotating sleeve 7 cannot rotate, the clamping block 13 completely slides out of the splicing groove 11, and then the reset spring 23 pushes the movable plate 24 to reset, so that the movable plate 24 pushes the splicing rod 12 to move, and then the splicing rod 12 and the splicing sleeve 8 are pulled to both sides respectively, the splicing rod 12 and the splicing sleeve 8 can be completely removed, and then the side panel 2 is removed. The internal resistance wire 28 can be inspected or maintained and replaced. After the inspection or maintenance is completed, the side panel 2 is installed back to its original position, and then the splicing rod 12 is passed through from one side, and then the splicing sleeve 8 is fitted to the outside of the splicing rod 12 from the other side. During the fitting process, one end of the splicing rod 12 will push the movable plate 24 to move, and then the movable plate 24 will squeeze the reset spring 23. When the reset spring 23 is squeezed to the limit, the rotating sleeve 7 is rotated in the opposite direction, and the rotating sleeve 7 drives the adapter block 9 to reset, and then the matching block 10 loses the limit of the adapter block 9, and then the spring 22 pushes the clamping block 13 to reset, so that the clamping block 13 is clamped into the splicing groove 11, and at the same time the clamping block 13 drives the matching block 10 to reset When the rotating sleeve 7 is completely reset, the conical spring 18 will drive the limiting rod 19 to re-engage in the original limiting groove 20, and then release the sliding sleeve 17, and the push spring 21 will push the sliding sleeve 17 to reset, and then the sliding sleeve 17 will drive the push rod 16 to reset, and then the rotating sleeve 14 will be rotated again, so that the rotating sleeve 14 drives the yield groove to move to a position that does not correspond to the push rod 16, so that the push rod 16 and the rotating sleeve 14 cooperate to limit the sliding sleeve 17 to prevent the sliding sleeve 17 from moving, and then the sliding sleeve 17 will limit the limiting rod 19 to prevent the limiting rod 19 from moving, and then the limiting rod 19 will cooperate with the limiting groove 20 to limit the rotating sleeve 7 to prevent the rotating sleeve 7 from rotating, thereby ensuring the stability of the installation structure.

[0038] See also Figure 1-4, as a further implementation of the overall device: an outer shell 26 is provided outside the inner shell 3, fastening plates 27 are symmetrically provided on both sides of the inner shell 3, and a heating wire 28 is provided between the inner shell 3 and the outer shell 26.

[0039] A feed hopper 29 is connected and provided on one side of the inner shell 3, and a discharge port 30 is connected and provided on the other side of the outer shell 26.

[0040] A motor 31 is installed on the mounting seat 1, a speed reducer 32 is provided on one side of the outer shell 26, the output end of the motor 31 is connected to the input end of the speed reducer 32, and the output end of the speed reducer 32 is connected to one end of the rotating shaft 6.

[0041] A bearing seat 33 is detachably provided on the mounting seat 1, and both ends of the rotating shaft 6 are respectively installed in the bearing seat 33.

[0042] More specifically, when the device needs to be used, first send the bonded paper rods into the feed hopper 29 and make the paper rods arranged neatly. Then turn on the motor 31. After being decelerated by the speed reducer, it drives the rotating shaft 6 to rotate. Then the rotating shaft 6 drives the feeding roller 4 to rotate, and the feeding roller 4 drives the card slots 5 to rotate. Then the paper rods will fall into the corresponding card slots 5 due to gravity and are sent into the inner shell 3 by the feeding roller 4. At the same time, the heating wire 28 provided between the inner shell 3 and the outer shell 26 is turned on, so that the heating wire 28 starts to work and generate heat, so that the adhesive dries quickly, and the paper rods are quickly dried. Then they are conveyed to an external conveyor through the discharge port 30 connected to the other side of the inner shell 3, thus realizing the orderly feeding of the paper rods without manual feeding one by one.

[0043] In summary, when the overall device is in use or operation: when it is necessary to repair, maintain, or replace the resistance wire 28, first rotate the rotating sleeve 14, so that the rotating sleeve 14 drives the relief hole 15 to move. When the relief hole 15 moves to a position corresponding to the ejector rod 16, the sliding sleeve 17 is pushed. The sliding sleeve 17 will drive the ejector rod 16 to pass through the relief hole 15. Then, the outer side of the limiting rod 19 will lose the limit of the limiting sleeve. Then rotate the rotating sleeve 7, and the rotating sleeve 7 will drive the limiting rod 19 to move. Due to the rounded corner structure design at the end of the limiting rod 19 and the edge of the limiting groove 20, when the side wall of the limiting groove 20 squeezes one end of the limiting rod 19, one end of the limiting rod 19 will slide out of the limiting groove 20. At the same time, the limiting rod 19 will drive the conical spring 18 to stretch. Then the rotating sleeve 7 will drive the adapter block 9 to move. Due to the special structure design of the adapter block 9, when the adapter block 9 moves with the rotating sleeve 7, the adapter block 9 will push the mating block 10 to move. Then the mating block 10 will drive the clamping block 13 to slide out of the splicing groove 11, and the clamping block 13 will squeeze the spring 22 arranged on one side. When the rotating sleeve 7 cannot rotate, the clamping block 13 completely slides out of the splicing groove 11. Then the return spring 23 will push the movable plate 24 to reset, so that the movable plate 24 pushes the splicing rod 12 to move. Then pull the splicing rod 12 and the splicing sleeve 8 to both sides respectively, and the splicing rod 12 and the splicing sleeve 8 can be completely removed. Then remove the side plate 2 to repair, maintain, or replace the internal resistance wire 28. When the repair, maintenance, or replacement is completed, install the side plate 2 back to its original position. Then pass the splicing rod 12 through from one side, and then sleeved the splicing sleeve 8 onto the outer side of the splicing rod 12 from the other side. During the sleeving process, one end of the splicing rod 12 will push the movable plate 24 to move, and then the movable plate 24 will squeeze the return spring 23. When the return spring 23 is squeezed to the limit, then rotate the rotating sleeve 7 in the reverse direction. The rotating sleeve 7 drives the adapter block 9 to reset. Then the mating block 10 loses the limit of the adapter block 9. Then the spring 22 pushes the clamping block 13 to reset, so that the clamping block 13 is clamped into the splicing groove 11. At the same time, the clamping block 13 will drive the mating block 10 to reset. When the rotating sleeve 7 is completely reset, the conical spring 18 will drive the limiting rod 19 to re-engage into the original limiting groove 20. Then loosen the sliding sleeve 17, and the push spring 21 pushes the sliding sleeve 17 to reset. Then the sliding sleeve 17 will drive the ejector rod 16 to reset. Then rotate the rotating sleeve 14 again, so that the rotating sleeve 14 drives the relief groove to move to a position not corresponding to the ejector rod 16, so that the ejector rod 16 and the rotating sleeve 14 cooperate to limit the sliding sleeve 17 to prevent the sliding sleeve 17 from moving. Then the sliding sleeve 17 will limit the limiting rod 19 to prevent the limiting rod 19 from moving. Then the limiting rod 19 and the limiting groove 20 cooperate to limit the rotating sleeve 7 to prevent the rotating sleeve 7 from rotating, thus ensuring the stability of the installation structure.

[0044] When the device needs to be used, first send the bonded paper rods into the feed hopper 29 and arrange the paper rods neatly. Then turn on the motor 31. After being decelerated by the speed reducer, the rotating shaft 6 is driven to rotate. Then the rotating shaft 6 drives the feeding roller 4 to rotate, and the feeding roller 4 drives the card slot 5 to rotate. Then the paper rods will fall into the corresponding card slots 5 due to gravity and are sent into the inner shell 3 by the feeding roller 4. At the same time, the heating wire 28 arranged between the inner shell 3 and the outer shell 26 is turned on, so that the heating wire 28 starts to work and generate heat, so that the adhesive dries quickly and the paper rods dry quickly. Then they are conveyed to an external conveyor through the discharge port 30 connected to the other side of the inner shell 3, so as to realize the orderly feeding of the paper rods without manual feeding one by one.
