Screw pump positive and negative pressure automatic detection equipment

Abstract

The invention relates to screw pump positive and negative pressure automatic detection equipment. The screw pump positive and negative pressure automatic detection equipment comprises a machine frame, wherein a stock bin is arranged on the machine frame; and the machine frame is further provided with an elevator, a feeding and screening mechanism, a center frame, a rotary table mechanism, a product carrying mechanism, a negative pressure detection mechanism, a positive pressure detection mechanism, a pressure maintaining detection mechanism, a screening and discharging mechanism and a pressure gauge mechanism. According to the screw pump positive and negative pressure automatic detection equipment, feeding of screw pumps, detection of pressing suction force, detection of existence of neglected installation of glass check beads and detection of station matching gaps of pump body parts can be automatically realized, multiple detection processes are integrated on one device, occupation of the workshop space is reduced, and types and number of devices are reduced, so that the cost of the devices is reduced. In addition, transferring, taking and placing operations of screw pump products among equipment can be omitted, the automation degree is high, the labor intensity can be reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the detection field of screw pump products, in particular to a positive and negative pressure automatic detection device for screw pumps. Background technique [0002] Screw pumps are usually used in daily necessities and cosmetics in liquid bottles. When the nozzle on the top of the screw pump is pressed, a negative pressure is generated inside the screw pump to suck the liquid in the bottle and finally realize the mist spray of the liquid. out. [0003] After the production and processing of screw pump products are completed, they need to be tested, including the detection of the pressing and suction force of the screw pump, the detection of missing glass check beads and the detection of the gap between pump body parts and stations. [0004] Existing tests for the above three types are performed step by step, corresponding to the three types of equipment. During the testing process, when a test is completed, it needs to be ...

Problems solved by technology

[0005] Each type of detection corresponds to a piece of equipment, which will undoubtedly lead to more types and quantities of equipment in the workshop, which will occupy more workshop space, and more types and quantities of equipment will directly lead to higher equipment procurement costs; at the same time, screw The transfer and pick-and-place operations of pumps between multiple devices will also consume a lot of manpower, which seriously restricts production efficiency
