Description

Technical Field

[0001] The present invention relates to a heat preservation container, and particularly to an automatic plastic screw ring sleeving device and process for the barrel body of a heat preservation container. Background Art

[0002] On the inner wall of the bottom of the barrel body of a heat preservation container product, there needs to be more than one circle of screw teeth. The screw teeth on the bottom part are connected to the barrel body in a spiral manner to lift the bottom against the bottom of the thermos bottle in the barrel body and need to withstand 5 - 10 N·m without loosening. In order to reduce the manufacturing difficulty and cost of the metal barrel body, the conventional method is that the screw teeth on the inner wall of the bottom of the barrel body are basically realized by additionally sleeving a plastic screw ring. Sometimes, in order to reduce the manufacturing difficulty or cost, a plastic screw ring is also sleeved on the inner wall of the bottom of the plastic barrel body in a structural manner. Through the interference fit or anti-rotation positioning fit between the screw ring and the barrel body, the bottom does not loosen during the spiral process and the bottom rotation torque meets the product quality requirements.

[0003] Currently, the plastic screw ring sleeving on the barrel body of heat preservation container products is basically manual operation. The traditional process has high labor intensity, unstable quality, low efficiency, and the barrel body is prone to defects such as scratching. The labor cost remains high, and the problems of unstable product quality and low production efficiency have always troubled the development of enterprises. With the increasing industrial automation and process innovation of enterprises, automated assembly devices and processes will become a new field of exploration. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic plastic screw ring sleeving device and process for the barrel body of a heat preservation container product to address the defects existing in the prior art.

[0005] The present invention includes: a frame, a bottom plate, connecting columns, a workbench, servo control module A, servo control module B, servo control module C, and an electrical control system. It is characterized in that servo control module A, servo control module B, and servo control module C are provided on the bottom plate. There is a servo motor on each of servo control module A, servo control module B, and servo control module C, which are respectively connected to slide table module A, slide table module B, and slide table module C through couplings and fixed on the bottom plate. The rotary cylinder installed on slide table module A is connected to the cylinder fixed block on stop cylinder A; positioning stop cylinder B and positioning stop cylinder C are respectively connected to slide table module B and slide table module C through profiling positioning B and profiling positioning C; positioning stop cylinder A is provided on the cylinder fixed block. The workbench is connected to the bottom plate through connecting columns, and the bottom plate is fixed on the frame. The electrical control system is arranged in the electrical box of the frame and is respectively connected to the rotary cylinder, positioning stop cylinder A, positioning stop cylinder B, positioning stop cylinder C, and the servo motors on servo control module A, servo control module B, and servo control module C through circuits. A preset program is set in the electrical control system.

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

[0007] The positioning and blocking B is provided on the positioning and blocking cylinder B, and the positioning and blocking B corresponds to the profiling positioning B. The positioning and blocking C is provided on the positioning and blocking cylinder C, and the positioning and blocking C corresponds to the profiling positioning C. There is a gap with a wall thickness of 0.5 - 3 mm of the plastic screw ring between the positioning and blocking B and the profiling positioning B, and there is a gap with a wall thickness of 0.5 - 3 mm of the plastic screw ring between the positioning and blocking C and the profiling positioning C.

[0008] The process of the present invention includes the following steps:

[0009] A. The plastic screw ring is sleeved on the profiling positioning A, profiling positioning B, and profiling positioning C protruding in the middle of the frame workbench;

[0010] B. The slide table module A, slide table module B, and slide table module C drive the positioning and blocking cylinder A, positioning and blocking cylinder B, and positioning and blocking cylinder C to move outwards, so that the profiling positioning A, profiling positioning B, and profiling positioning C connected to the positioning and blocking cylinder A, positioning and blocking cylinder

[0011] B, and positioning and blocking cylinder C are attached to the inner wall of the plastic screw ring, and the positioning and blocking cylinder A, positioning and blocking cylinder B, and positioning and blocking

[0012] cylinder C rise;

[0013] C. The rotary cylinder rotates 50 degrees vertically inwards. The slide table module A, slide table module B, and slide table

[0014] C drive the positioning and blocking cylinder A, positioning and blocking cylinder B, and positioning and blocking cylinder C to move inwards synchronously, so that the rotary cylinder drives the positioning and blocking cylinder A, profiling positioning A, cylinder fixing block, and positioning and blocking A to rotate 50 degrees vertically inwards synchronously to bend and deform the plastic screw ring downwards and converge. The positioning and blocking B and positioning and blocking C push the plastic screw ring inwards to deform and converge. After the screw ring is deformed, it is stressed on the workbench, profiling positioning A, profiling positioning B, and profiling positioning C to maintain a flexible deformation state without rebounding. The positioning and blocking cylinder A, positioning and blocking cylinder B, and positioning and blocking cylinder descend;

[0015] D. Place the body of the thermal insulation container on the workbench of the frame so that the plastic screw ring after being flexibly deformed and folded is inside the body. The slide table modules A, B, and C drive the positioning and blocking cylinders A, B, and C to retreat and move outward, and the rotary cylinder rotates vertically outward by 50 degrees synchronously, so that the bent and folded plastic screw ring returns to its original state and fits against the inner wall of the body.

[0016] E. The slide table modules A, B, and C drive the positioning and blocking cylinders A, B, and C to move forward and inward, so that the profiling positionings A, B, and C connected to the positioning and blocking cylinders A, B, and C

[0017] fold up. After taking out the metal body, the positioning and blocking cylinders A, B, and C drive the profiling positionings A, B, and C to rise, transfer to the next process, put another plastic screw ring again, and enter the next round of cyclic production.

[0018] The advantages of the present invention are that the automatic assembly process of the screw ring and the body is automatically completed by the automatic device, and full-automatic production can be achieved by the programmed actions preset by the device of the present invention and in cooperation with the manipulator. It solves the problems of high labor intensity, low efficiency, unstable quality and easy scratching in manual operation; saves operators, reduces production costs, and improves the quality and production efficiency of products; especially when manually sleeving, it is often difficult to cause the screw ring to break and be scrapped due to improper operation of personnel and excessive bending.
