Description

Technical Field

[0001] The invention relates to the technical field of household products, in particular to a foam particle blowing and filling device for a lazy sofa. Background Art

[0002] A lazy sofa is a large bag with a variety of outer materials and a non-woven cover with good air permeability. It is light and casual, can be placed anywhere, easy to move, takes up little space, is ergonomic, and has a soft and breathable fabric. Using a foam particle blowing device to fill a lazy sofa can use airflow to quickly blow a large amount of foam particles into the sofa cover, improve filling efficiency, meet large-scale production needs, and evenly distribute the foam particles to ensure uniform comfort and support of the sofa, and it is easy to operate.

[0003] Foam particle blowing and filling devices are mostly divided into manual blowing and filling devices, electric blowing and filling devices and pneumatic blowing and filling devices. Lazy sofas usually use electric blowing and filling devices in the blowing and filling process, including electric fan blowing and filling devices, which are composed of a storage box, an electric fan, a conveying pipeline and a control system. The fan generates airflow to blow the particles into the sofa. The filling efficiency is high and the filling is uniform and stable, which is suitable for large-scale production.

[0004] However, the electric fan filling device is prone to blockage during the conveying process. This is caused by solid particles in the foam raw materials, incompletely dissolved additives, or drying of the raw materials after long-term operation. Once blockage occurs, it will affect the normal operation of the filling machine. At this time, the device needs to be disassembled and cleaned. The existing disassembly structure mostly uses tools to rotate and remove the screws. Such a structure makes the disassembly process complicated and consumes a lot of time, resulting in the problem of reduced filling efficiency. Summary of the invention

[0005] In order to make up for the above shortcomings, the present invention provides a lazy sofa foam particle blowing and filling device, which aims to improve the problem that the device is prone to clogging in the prior art and needs to be disassembled and cleaned. However, the disassembly structure is usually complicated and takes a lot of time, resulting in reduced blowing and filling efficiency.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a foam particle blowing and filling device for a lazy sofa, comprising a mounting base, the upper surface of the mounting base is fixedly connected to a casing, one side of the outer wall of the casing is fixedly connected to a motor, the output end of the motor is fixedly connected to an impeller, a cover plate is arranged adjacent to one side of the outer wall of the casing, a mounting cylinder is fixedly connected to the cover plate, a bolt is threadedly connected to the inside of the mounting cylinder, one end of the bolt is fixedly connected to an abutment block, a clamping block is slidably connected to the inside of the mounting cylinder, one end of the clamping block is fitted with one end of the abutment block, a spring is sleeved on one side of the outer wall of the clamping block, one end of the spring is fixedly connected to the inside of the mounting cylinder, and a limit assembly for limiting the vertical movement distance of the bolt is installed inside the mounting cylinder.

[0007] Furthermore, the limiting assembly includes a limiting block, one side of the outer wall of the limiting block is fixedly connected to the inside of the installation tube, one side of the outer wall of the abutment block is slidably connected to the inside of the limiting block, and the lower surface of the bolt is in contact with the upper surface of the limiting block.

[0008] Furthermore, a mounting plate is fixedly connected to one side of the outer wall of the cover plate, and a connecting pipe is fixedly connected inside the mounting plate.

[0009] Furthermore, one end of the connecting pipe is fixedly connected to a placement box 1, and a slide groove is provided inside the placement box 1.

[0010] Furthermore, a second placement box is slidably connected inside the slide groove, a positioning hole is opened inside the second placement box, and a left-right symmetrical handle is fixedly connected to one side of the outer wall of the second placement box.

[0011] Furthermore, a spring 2 is fixedly connected to one side of an outer wall of the placement box, and a connecting plate is fixedly connected to one end of the spring 2.

[0012] Furthermore, a mounting block is fixedly connected to one side of the outer wall of the connecting plate, a rotating shaft is fixedly connected inside the mounting block, and one side of the outer wall of the rotating shaft is rotatably connected to the inside of the placement box.

[0013] Furthermore, a clamping column is fixedly connected to one side of the outer wall of the connecting plate, and one end of the clamping column is slidably connected to the inside of the positioning hole.

[0014] The present invention has the following beneficial effects:

[0015] 1. In the present invention, by rotating the bolt, the threaded connection between the bolt and the mounting cylinder causes the bolt to move, thereby driving the abutment block to move. Due to the conical design of the abutment block, the block moves, and the spring 1 sleeved on the outside of the block drives the block to return to its position by itself due to its elastic action, thereby achieving the effect of the block being engaged and disengaged from the inside of the casing, thereby achieving rapid installation and disassembly of the cover plate and the casing, which is simple and convenient, and solves the problem that the inside of the device is prone to blockage in the prior art, which not only affects the normal operation of the filling machine, but also takes a lot of time to clean and maintain, resulting in a problem of reduced blowing and filling efficiency, thereby improving the practicability of the device.

[0016] 2. In the present invention, by directly pressing the end of the connecting plate close to the second spring, the clamping column at the other end thereof is tilted up and disengaged from the positioning hole, and the second placement box can be moved at this time. By using the handle and the slide groove in coordination, the worker can change the contact area between the first placement box and the second placement box, thereby achieving the effect of conveniently changing the volume of the entire placement box, and then being able to adapt to different filling needs, thereby solving the problem that the existing filling device usually directly draws from the foam pile and cannot effectively and accurately control the output of the foam particles, thereby improving the practicality of the device.

When the abutment block 21 moves in the opposite direction, the elastic force of the spring 8 can make the block 7 automatically reset. A limit assembly for limiting the vertical movement distance of the bolt 5 is installed inside the installation cylinder 4. The limit assembly includes a limit block 6. One side of the outer wall of the limit block 6 is fixedly connected to the inside of the installation cylinder 4. One side of the outer wall of the abutment block 21 is slidably connected to the inside of the limit block 6. The lower surface of the bolt 5 fits with the upper surface of the limit block 6. The limit block 6 can also ensure that the bolt 5 moves within a certain range, thereby ensuring the operating accuracy and stability of the device.

[0026] Reference Figure 1 , Figure 2 and Figure 5A mounting plate 20 is fixedly connected to one side of the outer wall of the cover plate 3, and a connecting pipe 17 is fixedly connected inside the mounting plate 20. The connecting pipe 17 serves as a channel for conveying foam particles. One end of the connecting pipe 17 is fixedly connected to a placement box 9. A slide groove 15 is provided inside the placement box 9. The slide groove 15 provides a track for the sliding of the placement box 10, and also limits the sliding of the placement box 10 to prevent it from crushing the connecting pipe 17. The placement box 10 is slidably connected inside the slide groove 15. A positioning hole 19 is provided inside the placement box 10. The positioning hole 19 cooperates with the card column 16 to fix the position of the placement box 10 in the placement box 9. A left-right symmetrical handle 18 is fixedly connected to one side of the outer wall of the placement box 10. The handle 18 facilitates the operator to pull out the placement box 10. To make the operation more convenient and labor-saving, and improve work efficiency, a spring 2 13 is fixedly connected to one side of the outer wall of the placement box 19, and one end of the spring 2 13 is fixedly connected to a connecting plate 11, and a mounting block 12 is fixedly connected to one side of the outer wall of the connecting plate 11. A rotating shaft 14 is fixedly connected to the inside of the mounting block 12, and one side of the outer wall of the rotating shaft 14 is rotatably connected to the inside of the placement box 19. The rotating shaft 14 enables the connecting plate 11 to rotate around it to realize the insertion and extraction of the card column 16, and a card column 16 is fixedly connected to one side of the outer wall of the connecting plate 11, and one end of the card column 16 is slidably connected to the inside of the positioning hole 19. The card column 16 is a key component for realizing the fixation of the placement box 2 10. When the card column 16 is inserted into the positioning hole 19, the placement box 2 10 is firmly fixed in the placement box 19 to prevent displacement during the operation of the device.

[0027] Working principle: When in use, first adjust the appropriate volume of the placement box according to the filling requirements of the product. The worker first holds the handle 18, and then presses the connecting plate 11 close to the end of the spring 2 13. After pressing, the clamping column 16 will be lifted up and will be separated from the positioning hole 19, and then separated from the placement box 2 10, so that the placement box 2 10 can be easily slid. The volume of the placement box 2 10 can be adjusted by sliding. When the required volume is adjusted, press the connecting plate 11 again until the clamping column 16 is aligned and slides into the positioning hole 19. The slide groove 15 has a limiting effect on the placement box 2 10. Prevent the placement box 2 10 from sliding down too much and crushing the connecting pipe 17; when it is necessary to clean and repair the inside of the device, we need to remove the cover plate 3 from the casing 2, rotate the bolt 5, it moves in the vertical direction, the abutment block 21 gradually moves upward, and the block 7 returns to its position with the help of the elastic action of the spring 1 8, so the block 7 is separated from the casing 2 to realize the removal of the cover plate 3. When installing, rotate the bolt 5 in the opposite direction. Due to the conical design of the abutment block 21, the block 7 can move in the horizontal direction, so that the block 7 can be snapped into the inside of the casing 2 to achieve installation.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
