Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and particularly relates to an automatic raw tape winding device for hydrogen peroxide stability detection. Background Technique

[0002] Hydrogen peroxide is a common oxidant, which is widely used in the fields of chemical industry, pharmacy, environmental protection, etc. During storage and use, the stability of hydrogen peroxide is crucial. If the stability is insufficient, it may cause its decomposition, reduce its activity and pose safety hazards.

[0003] At present, the commonly used methods for hydrogen peroxide stability detection are mostly chemical analysis methods, and raw tape is required as a sealing material during the analysis process. However, manually winding the raw tape is cumbersome and difficult to ensure the reliability and consistency of winding, which easily affects the accuracy of test results, and the non-standard bandaging process may cause personal injury. To solve the above problems, the present experimental new model has developed an automatic raw tape winding auxiliary test device to improve the efficiency and accuracy of hydrogen peroxide stability detection. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem of poor efficiency and accuracy of the detection results caused by manually winding the raw tape in the above-mentioned background technique. Here, a new automatic raw tape winding device for hydrogen peroxide stability detection is proposed. This device can automatically use the raw tape to wind and seal the test bottle mouth, with consistent winding and high efficiency.

[0005] The technical solution adopted to achieve the above purpose is an automatic raw tape winding device for hydrogen peroxide stability detection, and the automatic raw tape winding device includes:

[0006] A base, on which a bracket is provided;

[0007] A clamping unit, which includes a first clamping block, a second clamping block, a fixed block and an adjusting bolt. The first clamping block and the fixed block are fixed on the base, the second clamping block is slidably connected to the base, one end of the second clamping block is rotatably connected to the adjusting bolt, and the adjusting bolt penetrates through the fixed block;

[0008] A winding unit, which includes a mounting plate, a nylon turntable, a winding tape fixing disk, a plurality of track wheels, a plurality of belt wheels, a driving wheel and a driving motor. Tracks are provided on the mounting plate, the track wheels and the belt wheels are installed in the tracks and rotatably connected to the mounting plate, the nylon turntable is rotatably connected to the track wheels and the belt wheels, the winding tape fixing disk is connected to the nylon turntable, the driving motor is fixed at the bottom of the mounting plate, the output end of the driving motor is fixedly connected to the driving wheel, and the driving wheel is driven by a belt to rotate with the rotating wheel;

[0009] Adjusting unit, the adjusting unit includes an adjusting block, a connecting member and a first locking screw. The adjusting block is provided with a plugging hole, the bracket passes through the plugging hole and is slidably connected to the adjusting block. One end of the first locking screw extends into the plugging hole, and the connecting member connects the adjusting block and the mounting plate.

[0010] In the above technical solution, the test bottle is fixed by the clamping unit, the raw material tape is wound around the mouth of the test bottle for sealing by the winding unit, and the height and angle of the winding unit are adjusted by the adjusting unit to achieve the winding and sealing of different test bottles, reducing the manual operation of the operator and greatly improving the winding efficiency and stability.

[0011] Further, the connecting member is a rotating shaft. One end of the connecting member is rotatably connected to the adjusting block, and the other end of the connecting member is fixedly connected to the mounting plate.

[0012] In the above technical solution, through the setting of the rotating shaft, the mounting plate can rotate, so as to ensure that the raw material tape is evenly wound at different angles and the sealing effect is better.

One end of the second locking screw passes through the through hole and is connected to the mounting plate, and the swing limit disc is fixedly connected to the adjusting block.

[0014] In the above technical solution, after adjusting the angle of the mounting plate through the rotating shaft, the mounting plate can be limited and fixed by the swing limit disc and the second locking screw to prevent the rotating shaft from loosening and affecting the winding effect during winding.

[0015] Further, the swing limit disc and the through hole are arc-shaped, and the center point of the adjusting block and the center point of the swing limit disc are on the same horizontal line.

[0016] In the above technical solution, through the arc-shaped setting, when the mounting plate changes the angle, the second locking screw can just resist against the mounting plate for fixation.

[0017] Further, the second locking screw is slidably connected to the swing limit disc.

[0022] Further, the PTFE tape automatic winding device further includes a controller, and the controller is electrically connected to the driving motor.

[0023] In the above technical solution, the start-stop and winding speed of the driving motor can be controlled by the controller to ensure the uniformity of winding and the sealing effect.
