Description

Technical Field

[0001] This application relates to the field of fishing line production, and in particular to an automatic heat shrinking device for fishing line spools. Background Technology

[0002] Fishing line is one of the fishing tools. It can be divided into two types: "line" and "silk". The line is made by twisting two or more strands of single yarn or silk together once or multiple times, while the silk is a single strand. The method of making fishing line is usually to melt the raw material and squeeze it out from a special spinneret hole. After cooling, stretching, winding and other processing, it is made into fishing line.

[0003] When fishing lines are produced, they are usually wound onto fishing line spools. To reduce the amount of fishing line unraveling on the spools during transportation and storage, a heat shrinking device is used to package the fishing line spools. Generally, a film is placed on the fishing line spool using a film-wrapping device, and then a heating oven is used to heat the film, causing it to shrink onto the fishing line spool.

[0004] When the fishing line spools are fed into the film-coating device and the heating oven, a conveyor belt is generally used to move the fishing line spools. After the fishing line spools are packaged, the fishing line falls from the end of the conveyor belt, where a collection hopper is placed. After the collection hopper is full, the worker replaces the collection hopper.

[0005] However, in actual operation, when the fishing line spool falls into the hopper, the worker needs to keep a close eye on it. If the worker does not have time to replace the hopper, the fishing line spool may fall from the hopper to the ground. Utility Model Content

[0006] The purpose of this application is to solve the problem mentioned in the background art that when the fishing line spool falls into the receiving hopper, workers need to keep a close eye on it, and if the workers do not have time to replace the receiving hopper, the fishing line spool may fall from the receiving hopper to the ground. This application provides an automatic heat shrinking device for fishing line spools.

[0007] To achieve the above objectives, this application specifically adopts the following technical solution:

[0008] An automatic heat-shrinking device for fishing line spools includes a conveyor belt with a film-wrapping device mounted on it. The conveyor belt passes through the film-wrapping device. A heating oven is located on one side of the conveyor belt, passing through it. Several evenly distributed positioning rods are fixed on the conveyor belt. Two symmetrical feeding plates are fixed at the end of the conveyor belt near the heating oven. Two receiving hoppers are located at the end of the conveyor belt near the heating oven. A conversion mechanism is provided between the conveyor belt and the two receiving hoppers. The conversion mechanism includes a support base located at the end of the conveyor belt near the heating oven. Two movable seats are mounted on the support base. Two symmetrical limiting plates are fixed on each of the two movable seats. The receiving hoppers are located between adjacent limiting plates. A driving assembly is provided between the support base and the two movable seats. A locking assembly is provided on the receiving hoppers. A laser sensor is fixed inside the receiving hoppers.

[0009] By adopting the above technical solution, when the fishing line spools in the receiving hopper are full, the spools block the laser sensor, and then the drive component is activated. The drive component drives two moving seats to move simultaneously, and the two moving seats drive the corresponding limit plates. The limit plates drive the receiving hopper, allowing the receiving hopper full of fishing line spools to move away from under the conveyor belt. The empty receiving hopper moves to under the conveyor belt, allowing the fishing line spools to fall into the empty receiving hopper. This facilitates the collection of continuously feeding fishing line spools and reduces the possibility that the fishing line spools may fall out of the receiving hopper because workers do not have time to change the receiving hopper.

[0010] Furthermore, the drive assembly includes two support rods symmetrically fixed on the support base, and threaded rods are rotatably connected to the two support rods. The threaded rods pass through the two movable seats and are threadedly connected to the movable seats. A drive motor is fixed on one of the support rods, and the output end of the drive motor passes through the support rod and is fixedly connected to the threaded rod.

[0011] By adopting the above technical solution, the drive motor drives the threaded rod, which in turn drives the two moving seats to move simultaneously, thus making it convenient for the two moving seats to drive the corresponding receiving hoppers to move simultaneously.

[0012] Furthermore, a limiting rod is fixed between the two support rods, the limiting rod passing through the two movable seats and being slidably connected to the movable seats.

[0013] By adopting the above technical solution, the moving rod is limited by the limiting rod, thereby enabling the moving seat to move stably on the threaded rod.

[0014] Furthermore, a buffer pad is fixed on the inner wall of the receiving hopper.

[0015] By adopting the above technical solution, when the fishing line spool falls into the empty hopper, the buffer pad inside the hopper cushions the fishing line spool, thereby reducing the collision between the fishing line spool and the hopper.

[0016] Furthermore, the snap-fit ​​assembly includes a snap-fit ​​rod on one side of the receiving hopper, the snap-fit ​​rod is slidably connected to the limiting plate, and a snap-fit ​​spring is provided on the snap-fit ​​rod, with both ends of the snap-fit ​​spring being fixedly connected to the snap-fit ​​rod and the limiting plate.

[0017] By adopting the above technical solution, after the receiving hopper is completely moved into the two limiting plates, the locking rod extends under the push of the locking spring. The locking rod restricts the receiving hopper, so that the receiving hopper is stably positioned between the two limiting plates, thereby enabling the receiving hopper to be stably positioned between the two limiting plates.

[0018] Furthermore, the snap-fit ​​rod has an inclined surface, which corresponds to the receiving hopper.

[0019] By adopting the above technical solution, the hopper is pressed against the inclined surface of the clamping rod, and the clamping rod is pressed against the clamping spring, thereby making it easy for the hopper to be inserted between the two limiting plates.

[0020] Furthermore, several support rollers are rotatably connected to the support base, and the support rollers abut against the receiving hopper.

[0021] By adopting the above technical solution, the limiting plate drives the receiving hopper to move on the support roller on the support seat, thereby reducing the friction between the receiving hopper and the support seat.

[0022] Furthermore, a baffle is provided between the two receiving hoppers, and the baffle is fixedly connected to a limiting plate between adjacent receiving hoppers.

[0023] By adopting the above technical solution, the baffle guides and blocks the falling fishing line spool, causing it to fall into one of the two collection hoppers, thereby reducing the possibility of the fishing line spool hitting the space between the two collection hoppers and falling out.

[0024] In summary, this application includes at least one of the following beneficial effects;

[0025] 1. This application achieves the purpose of conveniently collecting continuously feeding fishing line spools by having the fishing line spools block the laser sensor when the hopper is full, and then activating the drive component. The drive component drives two moving seats to move simultaneously, and the two moving seats drive corresponding limit plates. The limit plates drive the hopper, so that the hopper full of fishing line spools moves away from under the conveyor belt. The empty hopper moves under the conveyor belt, allowing the fishing line spools to fall into the empty hopper. Then, the locking component releases the restriction of the hopper, and the hopper is pulled down from the support seat to be placed into a new hopper. This achieves the purpose of conveniently collecting continuously feeding fishing line spools and reducing the possibility of fishing line spools falling out of the hopper due to workers not having time to change the hopper.

[0026] 2. In this application, when the receiving hopper is removed from the support base, the locking rod is pulled directly to release it from its restraint. The receiving hopper is then pulled directly out from between the two limiting plates. The new receiving hopper is then positioned between the two limiting plates of the moving base, allowing it to press against the inclined surface of the locking rod. This causes the locking rod to press against the locking spring. After the receiving hopper has completely moved into the two limiting plates, the locking rod extends under the push of the locking spring. The locking rod restrains the receiving hopper, ensuring it remains stably positioned between the two limiting plates. This achieves the goal of ensuring the receiving hopper is stably positioned between the two limiting plates while facilitating its removal from between them. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0034] This application discloses an automatic heat shrinking device for fishing line spools.

[0035] Reference Figure 1 , Figure 2 and Figure 3An automatic heat shrinking device for fishing line spools includes a conveyor belt 1, a film-coating device 2 mounted on the conveyor belt 1, the conveyor belt 1 passing through the film-coating device 2, a heating oven 3 mounted on one side of the conveyor belt 1, the conveyor belt 1 passing through the heating oven 3, several evenly distributed positioning rods 4 fixed on the conveyor belt 1, two symmetrical feeding plates 5 fixed at one end of the conveyor belt 1 near the heating oven 3, two receiving hoppers 6 mounted at one end of the conveyor belt 1 near the heating oven 3, a conversion mechanism 7 between the conveyor belt 1 and the two receiving hoppers 6, the conversion mechanism 7 including a support base 71 mounted on one end of the conveyor belt 1 near the heating oven 3, two movable seats 72 mounted on the support base 71, two symmetrical limiting plates 73 fixed on each of the two movable seats 72, the receiving hoppers 6 located between adjacent limiting plates 73, a drive assembly 74 between the support base 71 and the two movable seats 72, a snap-fit ​​assembly 75 mounted on the receiving hoppers 6, and a laser sensor 76 fixed inside the receiving hoppers 6.

[0036] During the thermoforming process of fishing line spools, workers place the spools one by one onto the moving conveyor belt 1, allowing them to be fitted onto the positioning rod 4. The conveyor belt 1 carries the spools past the film-fitting device 2, which applies a film to the spools. The conveyor belt 1 then continues to move the film-fitted spools into the heating oven 3, where the film is shrunken onto the spools. The spools then pass over the unloading plate 5, which removes them from the positioning rod 4. The spools fall from the conveyor belt 1 into the receiving hopper 6 below it. When the receiving hopper 6 is full, the spools block the laser sensor 76, and the drive assembly 74 is activated. The drive assembly 74 moves two moving seats 72 simultaneously, and the two moving seats 72 move their corresponding... The limiting plate 73 drives the receiving hopper 6, allowing the full receiving hopper 6 to move away from under the conveyor belt 1. The empty receiving hopper 6 moves below the conveyor belt 1, allowing the fishing line to fall into the empty receiving hopper 6. Then, the locking component 75 releases the restriction on the receiving hopper 6, and then pulls the receiving hopper 6, allowing the full receiving hopper 6 to be pulled off the support base 71 and placed into a new receiving hopper 6. By using the receiving hopper 6 to hold the fishing line, when the receiving hopper 6 is full, the driving component 74 drives the two moving seats 72, which use the limiting plate 73 to move the receiving hopper 6, allowing the receiving hopper 6 to be switched. This facilitates the collection of continuously feeding fishing line, reducing the possibility that the fishing line may fall out of the receiving hopper 6 because the workers do not have time to change it.

[0037] Reference Figure 1 and Figure 2The drive assembly 74 includes two support rods 741 symmetrically fixed on the support base 71. Threaded rods 742 are rotatably connected to the two support rods 741. The threaded rods 742 pass through the two movable seats 72 and are threadedly connected to the movable seats 72. A drive motor 743 is fixed on one of the support rods 741. The output end of the drive motor 743 passes through the support rod 741 and is fixedly connected to the threaded rod 742.

[0038] In addition, a limiting rod 744 is fixed between the two support rods 741. The limiting rod 744 passes through the two movable seats 72 and is slidably connected to the movable seats 72.

[0039] Furthermore, a buffer pad 77 is fixed on the inner wall of the receiving hopper 6.

[0040] When it is necessary to move the two moving seats 72, the drive motor 743 directly drives the threaded rod 742, which in turn drives the two moving seats 72 to move simultaneously. The two moving seats 72 drive the corresponding limiting plates 73, which in turn drive the receiving hopper 6 to move laterally on the support seat 71, allowing the empty receiving hopper 6 to move below the conveyor belt 1, and the full receiving hopper 6 to move away from below the conveyor belt 1. When the fishing line spool falls into the empty receiving hopper 6, the buffer pad 77 inside the receiving hopper 6 cushions the fishing line spool. By having the threaded rod 742 drive the two moving seats 72 to move simultaneously, and the two moving seats 72 drive the two receiving hoppers 6 to switch on the support seat 71, it is possible to easily allow the moving seats 72 to drive the two receiving hoppers 6 to move simultaneously.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The snap-fit ​​assembly 75 includes a snap-fit ​​rod 751 on one side of the receiving hopper 6. The snap-fit ​​rod 751 is slidably connected to the limiting plate 73. A snap-fit ​​spring 752 is provided on the snap-fit ​​rod 751. Both ends of the snap-fit ​​spring 752 are fixedly connected to the snap-fit ​​rod 751 and the limiting plate 73.

[0042] In addition, the clamping rod 751 has an inclined surface, which corresponds to the receiving hopper 6.

[0043] When removing the receiving hopper 6 from the support base 71, pull the locking rod 751 directly to release it from its restraint on the receiving hopper 6. Then, pull the receiving hopper 6 directly out from between the two limiting plates 73. Position the new receiving hopper 6 between the two limiting plates 73 of the moving base 72, allowing the receiving hopper 6 to press against the inclined surface of the locking rod 751, causing the locking rod 751 to press against the locking spring 752. After the receiving hopper 6 has completely moved into the two limiting plates 73, the locking rod 751 extends under the push of the locking spring 752, restraining the receiving hopper 6 and keeping it stable between the two limiting plates 73. By using the locking rod 751 to restrain the receiving hopper 6 between the two limiting plates 73 on the moving base 72, the receiving hopper 6 can be stably positioned between the two limiting plates 73, while also facilitating the removal of the receiving hopper 6 from between the two limiting plates 73.

[0044] Reference Figure 1 and Figure 2 Several support rollers 8 are rotatably connected to the support base 71, and the support rollers 8 abut against the receiving hopper 6. When the limiting plate 73 on the moving base 72 moves the receiving hopper 6, the limiting plate 73 moves the receiving hopper 6 on the support rollers 8 on the support base 71, and the support rollers 8 rotate on the support base 71. By using the support rollers 8 to support the receiving hopper 6, the friction between the receiving hopper 6 and the support base 71 can be reduced.

[0045] Reference Figure 1 and Figure 2 A baffle 9 is installed between the two receiving hoppers 6, and the baffle 9 is fixedly connected to the limiting plate 73 between the adjacent receiving hoppers 6. When the two receiving hoppers 6 move, they move simultaneously. When the two receiving hoppers 6 are located between the two receiving hoppers 6 and below the conveyor belt 1, the baffle 9 guides and blocks the falling fishing line spool, causing the fishing line spool to fall into one of the two receiving hoppers 6. By using the baffle 9 to fix the two receiving hoppers 6 and to guide the falling fishing line spool, the possibility of the fishing line spool hitting the space between the two receiving hoppers 6 and falling off can be reduced.

[0046] Working principle: During the thermoforming process of fishing line spools, workers place the spools one by one onto the moving conveyor belt 1, allowing them to be fitted onto the positioning rod 4. The conveyor belt 1 carries the spools past the film-fitting device 2, which applies a film to the spools. The conveyor belt 1 then continues to move the film-fitted spools into the heating oven 3, where the film is shrunken onto the spools. The spools then pass over the discharge plate 5, which removes them from the positioning rod 4. The spools fall from the conveyor belt 1 into the receiving hopper 6 below it. When the receiving hopper 6 is full, the spools block the laser sensor 76, triggering the drive motor 743 to move the threaded rod 742. The threaded rod 742 then moves two moving seats 72 simultaneously, which in turn move their corresponding... Limiting plate 73 drives the receiving hopper 6 to move laterally on support base 71, allowing the empty receiving hopper 6 to move below conveyor belt 1 and the full receiving hopper 6 to move away from below conveyor belt 1. Then, the worker directly pulls the clamping rod 751 to release the clamping rod 751 from the restriction of the receiving hopper 6, and then directly pulls the receiving hopper 6 out between the two limiting plates 73. Then, the new receiving hopper 6 is placed between the two limiting plates 73 of the moving base 72, allowing the receiving hopper 6 to press against the inclined surface on the clamping rod 751, allowing the clamping rod 751 to press against the clamping spring 752. After the receiving hopper 6 has completely moved into the two limiting plates 73, the clamping rod 751 extends under the push of the clamping spring 752, and the clamping rod 751 restricts the receiving hopper 6, allowing the receiving hopper 6 to be stably placed between the two limiting plates 73, completing the replacement of the receiving hopper 6.
