Abstract
Description
Technical Field
[0001] This utility model relates to the field of directional pulley technology, specifically a directional pulley limiting device. Background Technology
[0002] Tape packaging machines are widely used automated equipment in industrial production. They are mainly used to apply tape to cartons or other packaging containers to achieve a fast and efficient sealing operation. These machines offer significant advantages in improving packaging efficiency, reducing costs, and minimizing human error.
[0003] The tape packaging machine includes a machine body, a feeding structure, a guiding structure, and an adhesive structure. The feeding structure feeds the tape from the tape roll to the adhesive structure, which then adhesiveally attaches the tape to a carton or paper bag. The guiding structure is located between the feeding structure and the adhesive structure and consists of multiple guide wheels, also called directional pulleys. These guide wheels guide the tape smoothly onto the adhesive structure, facilitating the adhesive application.
[0004] Regarding the above technical conditions, there is also a defect that the guide wheel does not have a limiting structure for the conveyor belt, and the conveyor belt is prone to slipping off the directional pulley during the operation of the machine.
[0005] Based on this, the present invention designs a directional pulley limiting device to solve the above problems. Utility Model Content
[0006] The purpose of this utility model is to provide a directional pulley limiting device to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a directional pulley limiting device, comprising a body and a guide wheel, a fixed shaft fixedly mounted on the body, the guide wheel rotatably mounted on the fixed shaft, a limiting component mounted on the fixed shaft, the limiting component comprising a torsion spring, an elastic ring, a fixed rod, and a rubber sleeve, the torsion spring comprising a spring portion and a linear portion, two of which are respectively fixedly connected to the two ends of the spring portion, the guide wheel being located between the two linear portions, the spring portion being above the guide wheel, the elastic ring being fixedly connected to the linear portion, the elastic ring being sleeved on the fixed shaft, the elastic ring being a partially closed ring, the fixed rod being fixedly connected to the end of the elastic ring away from the linear portion, the rubber sleeve being sleeved on the linear portion, and the rubber sleeve being sleeved on the fixed rod.
[0008] Preferably, a limiting plate is fixedly provided on the fixed shaft, and multiple limiting plates are provided on the fixed shaft.
[0009] Preferably, an anti-stick layer is fixedly provided on the outer surface of the limiting component.
[0010] Preferably, the guide wheel is provided with a limiting groove.
[0011] Preferably, a protective block is fixedly mounted on the fixing rod, and the protective block is made of soft silicone material.
[0012] In summary, this application has the following beneficial technical effects: In use, the straight section and the fixed rod are separated in opposite directions, opening an opening in the elastic ring. The elastic ring is then fitted onto the fixed shaft. Finally, the rubber sleeve is lowered so that it fits onto both the straight section and the fixed rod. Under the action of the rubber sleeve, the limiting component is stably installed on the fixed shaft. The tape is then installed on the guide wheel, with the tape positioned between the guide wheel and the spring section. The tape is tightened, the spring section presses against the tape, and the tape presses against the limiting groove of the guide wheel. Under the action of the limiting component and the limiting groove, the tape is less likely to slip off the guide wheel during operation, thus achieving the effect of preventing the tape from slipping off the guide wheel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0023] A directional pulley limiting device includes a body 1 and a guide wheel 5. A fixed shaft 12 is fixedly mounted on the body 1, and the guide wheel 5 is rotatably mounted on the fixed shaft 12, guiding the conveyor belt. A limiting component 2 is provided on the fixed shaft 12, limiting the conveyor belt on the guide wheel 5 to prevent it from slipping off the guide wheel 5.
[0024] The limiting assembly 2 includes a torsion spring, an elastic ring 11, a fixing rod 9, and a rubber sleeve 10. The torsion spring includes a spring portion 6 and a linear portion 7. Two linear portions 7 are provided, and each linear portion 7 is fixedly connected to the spring portion 6. The guide wheel 5 is located between the two linear portions 7, and the spring portion 6 is above the guide wheel 5. The elastic ring 11 is fixedly connected to the linear portion 7 and is sleeved on the fixing shaft 12.
[0025] The elastic ring 11 is a partially closed ring. The fixing rod 9 is fixedly connected to the end of the elastic ring 11 away from the straight section 7. The rubber sleeve 10 is fitted onto the straight section 7 and the fixing rod 9. After the elastic ring 11 of the limiting component 2 is fitted onto the fixing shaft 12, the rubber sleeve 10 is fitted onto the straight section 7 and the fixing rod 9 respectively. Under the action of the rubber sleeve 10, the limiting component 2 is stably installed on the fixing shaft 12. In use, the tape is pressed against the outer surface of the guide wheel 5, so that the tape is between the spring part 6 and the guide wheel 5. When the tape is tightened, the spring part 6 presses against the tape, and the tape presses against the guide wheel 5. The tape is limited between the guide wheel 5 and the limiting component 2, and the tape is not easy to slip off the guide wheel 5.
[0026] A limiting plate 4 is fixedly installed on the fixed shaft 12. Multiple limiting plates 4 are provided on the fixed shaft 12. The elastic ring 11 is between the multiple limiting plates 4. The limiting plates 4 limit the elastic ring 11, so that the range of motion of the elastic ring 11 is between the multiple limiting plates 4.
[0027] An anti-stick layer is fixedly provided on the outer surface of the limiting component 2 to prevent the tape from sticking to the limiting component 2. A limiting groove 3 is provided on the guide wheel 5, which serves to limit the tape and further prevent it from slipping off the guide wheel 5. A protective block 8 is fixedly provided on the fixing rod 9. The protective block 8 is made of soft silicone material. When the rubber sleeve 10 is fitted on the fixing rod 9, the protective block 8 prevents the end of the fixing rod 9 from damaging the rubber sleeve 10, thus extending the service life of the rubber sleeve 10.
[0028] The implementation principle of this embodiment is as follows: In use, the straight section 7 and the fixed rod 9 are separated in opposite directions, and the elastic ring 11 is opened. The elastic ring 11 is then fitted onto the fixed shaft 12. Finally, the rubber sleeve 10 is moved down so that it is fitted onto the straight section 7 and the fixed rod 9 respectively. Under the action of the rubber sleeve 10, the limiting component 2 is stably installed on the fixed shaft 12. The tape is installed on the guide wheel 5, so that the tape is between the guide wheel 5 and the spring section 6. The tape is tightened, the spring section 6 presses against the tape, and the tape presses against the limiting groove 3 of the guide wheel 5. Under the action of the limiting component 2 and the limiting groove 3, the tape is not easy to slip off the guide wheel 5 during operation, thus achieving the effect of preventing the tape from slipping off the guide wheel 5.
