Description

TECHNICAL FIELD

[0001] The utility model relates to screw cap equipment field, concretely relates to a kind of glass bottle line screw cap equipment of eliminating transition screwing. BACKGROUND

[0002] Screw cap equipment, also known as capping machine, capping machine or locking cap machine, is a crucial device in the bottling industry. The screw cap equipment tightly seals the bottle cap on the bottle mouth through rotary motion and pressure control, ensuring the sealing and safety of the product. The screw cap equipment has the functions of automatic cap sorting, cap applying and automatic cap screwing, and can process bottles at high speed, significantly improving production efficiency. Moreover, the screw cap equipment can automatically adjust according to different cap and bottle mouth sizes, showing strong adaptability.

[0003] The patent document with publication number CN216190964U discloses a high-efficiency automatic screw cap equipment, which includes a lifting mechanism, a screw cap mechanism and a screw cap positioning jig for positioning the product to be screwed. The screw cap mechanism is installed on the lifting mechanism and driven by the lifting mechanism to move vertically. The screw cap mechanism includes a screw cap assembly and a screw cap driving device for driving the screw cap assembly to rotate. The screw cap assembly includes a screw cap head and a tightening head fixedly installed at the bottom of the screw cap head. The bottom of the tightening head is provided with a tightening slot, and the tightening slot is internally provided with a separable column that can move up and down. The screw cap positioning jig is arranged directly below the tightening head. This screw cap equipment can ensure the flatness of the product during screwing and automatically push the product out after screwing, greatly improving the screwing effect and production efficiency. The screw torque is easy and reliable to adjust, and the equipment is suitable for various products. However, there are still some shortcomings.

[0004] The screw cap equipment in the above patent document fixes the bottle through the screw cap positioning jig, and then drives the screw cap mechanism to move down through the lifting mechanism, so that the screw cap mechanism tightens the bottle cap. However, the existing screw cap equipment is affected by inertia during the screwing process, and the claw head continues to rotate under the action of inertia when the torque reaches the target value, which easily causes the bottle cap to be screwed excessively, thereby damaging the cap and making it difficult to unscrew the bottle cap. Therefore, a screw cap equipment for glass bottles is proposed to eliminate the transition screwing and solve the above problems. UTILITY MODEL CONTENTS
