Description

Technical Field

[0001] This utility model relates to an insulated container, and more particularly to an automatic plastic screw ring fitting device for the body of the insulated container. Background Technology

[0002] The inner wall of the bottom of the insulated container needs to have at least one ring of threads. These threads connect to the container body via a spiral mechanism, supporting the bottom of the insulated bottle liner inside the body and preventing it from loosening (5-10 N·m). To reduce the manufacturing difficulty and cost of the metal container body, the conventional method is to use an additional plastic screw ring on the inner wall of the bottom. Sometimes, to further reduce manufacturing difficulty or cost, an additional plastic screw ring is also used on the inner wall of the bottom of a plastic container. Through an interference fit or anti-rotation positioning fit between the screw ring and the container body, the bottom remains secure during the spiral process, and the rotational torque at the bottom meets product quality requirements.

[0003] Currently, the installation of plastic screw rings on the cylinders of insulated containers is primarily done manually. This traditional process is labor-intensive, results in inconsistent quality, low efficiency, and easily leads to defects such as scratches on the cylinder body. High labor costs, coupled with inconsistent product quality and low production efficiency, have long plagued the development of enterprises. As industrial automation and process innovation increase, automated assembly equipment and processes will become a new area of ​​exploration. Summary of the Invention

[0005] This utility model includes: a frame, a base plate, connecting columns, a worktable, servo control module A, servo control module B, servo control module C, and an electrical control system. The base plate is characterized by having servo control modules A, B, and C. Each servo control module has a servo motor connected to slide modules A, B, and C respectively via couplings and fixed to the base plate. A rotary cylinder mounted on slide module A is fixed to a cylinder on blocking cylinder A. The blocks are connected; positioning and blocking cylinders B and C are connected to slide module B and slide module C respectively via contour positioning B and contour positioning C; positioning and blocking cylinder A is provided on the cylinder fixing block; the worktable is connected to the base plate through the connecting column; the base plate is fixed on the frame; the electrical control system is set in the electrical box of the frame; and is connected to the servo motors on the rotary cylinder, positioning and blocking cylinder A, positioning and blocking cylinder B, positioning and blocking cylinder C, servo control module A, servo control module B, and servo control module C via circuits; the electrical control system has a preset program.

[0006] The positioning blocking cylinder A is fixed on the cylinder fixing block and connected to the rotary cylinder. The front end of the cylinder fixing block is provided with a contour positioning A. The positioning blocking A is connected to the positioning blocking cylinder A. There is a gap of 0.5 to 3.5 mm plastic screw ring wall thickness between the positioning blocking A and the contour positioning A.

[0007] The positioning blocking cylinder B is provided with a positioning blocking B, which corresponds to the contour positioning B. The positioning blocking cylinder C is provided with a positioning blocking C, which corresponds to the contour positioning C. A gap of 0.5 to 3 mm plastic screw ring wall thickness is left between the positioning blocking B and the contour positioning B. A gap of 0.5 to 3 mm plastic screw ring wall thickness is left between the positioning blocking C and the contour positioning C.

[0008] The advantages of this invention are that it automates the assembly process of the screw ring and the cylinder body through an automated device. The device's pre-programmed actions, combined with a robotic arm, enable fully automated production. This solves the problems of high labor intensity, low efficiency, unstable quality, and susceptibility to scratches associated with manual labor. It saves on operator time, reduces production costs, and improves product quality and production efficiency. In particular, it addresses the common problem of screw ring breakage and scrapping due to improper operation and excessive bending during manual assembly. Attached Figure Description

[0018] The embodiments of this utility model are further described below with reference to the accompanying drawings:

[0019] See Figures 1 to 8 This embodiment consists of a frame 1, a base plate 2, a connecting column 3, a worktable 4, servo control modules A 5, B 6, and C 7, and an electrical control system 8. The base plate 1 is equipped with servo control modules A5, B 6, and C 7. Each of these modules has a servo motor connected to slide modules A11, B12, and C13 respectively via couplings 24 and is fixed to the base plate 1. A rotary cylinder 10 is connected to slide module A11; the rotary cylinder 10 mounted on slide module A11 is connected to a cylinder fixing block 20 on the positioning and blocking cylinder A14. Positioning and blocking cylinders B15 and C16 are connected to slide module B12 and slide module C13 via contour positioning B18 and contour positioning C19. Positioning and blocking cylinder A14 is provided on cylinder fixing block 20. Positioning and blocking cylinder A14 is fixed on cylinder fixing block 20 and connected to rotary cylinder 10. Contour positioning A17 is provided at the front end of cylinder fixing block 20. Positioning block A21 is connected to positioning and blocking cylinder A14. A gap of 0.5 to 3.5 mm plastic screw ring 9 wall thickness is left between positioning block A21 and contour positioning A17. Positioning stop cylinder B15 is equipped with positioning stop B22, which corresponds to contour positioning B18. Positioning stop cylinder C16 is equipped with positioning stop C23, which corresponds to contour positioning C19. A gap of 0.5 to 3 mm plastic screw ring wall thickness is left between positioning stop B22 and contour positioning B18, and a gap of 0.5 to 3 mm plastic screw ring wall thickness is left between positioning stop C23 and contour positioning C19.

[0020] The workbench 4 is connected to the base plate 2 via the connecting column 3, and the base plate 2 is fixed on the frame 1. The electrical control system 8 is located in the electrical box of the frame 1, and is connected to the servo motors on the rotary cylinder 10, positioning and blocking cylinder A14, positioning and blocking cylinder B15, positioning and blocking cylinder C16, servo control module A5, servo control module B6, and servo control module C7 via circuits. The electrical control system 8 has a preset program.

[0021] The device of this utility model shall be operated according to the following steps:

[0022] First, put the plastic screw ring 9 onto the protruding contour positioning A17, contour positioning B18, and contour positioning C19 in the middle of the worktable 4 of the frame 1.

[0023] Then, slide modules A11, B12, and C13 drive positioning and blocking cylinders A14, B15, and C16 to move outward, causing the contour positioning A17, B18, and C19 connected to the positioning and blocking cylinders A14, B15, and C16 to fit against the inner wall of the plastic screw ring 9, and the positioning and blocking cylinders A14, B15, and C16 to rise.

[0024] Subsequently, the rotary cylinder 10 rotates 50 degrees vertically inward. ， Slide modules A11, B12, and C13 drive positioning and blocking cylinders A14, B15, and C16 to move inward simultaneously, causing rotary cylinder 10 to drive positioning and blocking cylinder A14, contour positioning A17, cylinder fixing block 20, and positioning block A21 to rotate vertically inward by 50 degrees simultaneously, causing the plastic screw ring 9 to bend downward and deform. Positioning blocks B22 and C23 push the plastic screw ring 9 to move inward and deform, and after deformation, the plastic screw ring 9 is subjected to force on the worktable 4, contour positioning A17, B18, and C19 and remains in a flexible deformed state without rebounding. Positioning and blocking cylinders A14, B15, and C16 descend.

[0025] Next, the metal cylinder 25 of the insulated container is placed on the workbench 4 of the frame 1 so that the plastic screw ring 9, after being flexibly deformed and retracted, is inside the cylinder. The slide modules A11, B12, and C13 drive the positioning and blocking cylinders A14, B15, and C16 to move backward and outward. The rotating cylinder 10 rotates vertically outward at the same time, so that the bent and retracted plastic screw ring 9 returns to its original shape and adheres to the inner wall of the metal cylinder 25.

[0026] Finally, slide modules A11, B12, and C13 drive positioning and blocking cylinders A14, B15, and C16 to move forward and inward, causing the contour positioning cylinders A17, B18, and C19 connected to them to retract, and the metal cylinder body 25 (see internal screw ring) after the internal screw ring is removed. Figure 8 Then, positioning blocking cylinders A14, B15, and C15 drive contour positioning cylinders A17, B18, and C19 to rise, proceed to the next process, and insert another plastic screw ring 9 to enter the next round of production.
