Detailed Description

The invention is further described below with reference to examples and figures thereof.

As shown in fig. 1 to 4, the non-contact sucker based on the coanda effect of the present invention comprises a non-contact sucker body 3, an energy saving device 6 and a blocking pin 4, wherein the energy saving device 6 comprises a housing 2 and a fluid passage tube 9, a 5mm outlet pipe 10 at the lower end of the fluid passage tube 9 is connected with the upper end of the non-contact sucker body 3 through a thread, and a sealing gasket is arranged between the outlet pipe and the upper end of the fluid passage tube; the outer side of the upper end of the fluid channel pipe 9 is sleeved with a shell 2, the shell 2 is connected with the fluid channel pipe 9 through threads, and a sealing gasket is arranged between the shell 2 and the fluid channel pipe 9; a primary air inlet 1 is arranged on the shell 2, a ventilation cavity 11 is reserved between the shell 2 and the fluid channel pipe 9, the primary air inlet 1 is communicated with the ventilation cavity, the blocking pin 4 is arranged at the lower end of the non-contact sucker body through threads, and a sealing gasket is arranged between the blocking pin and the non-contact sucker body; the lower surface of the non-contact sucker body 3 is provided with an airflow guide groove 5 with the width of 3mm, the edge of the lower surface of the non-contact sucker body 3 is a 60-degree arc line, the bottom of the blocking foot 4 is provided with an anti-slip pad, and the cross section of the inner wall of the shell 2 is in a horn shape.

The primary air inlet hole 1 comprises a main air inlet hole 1A and two standby air inlet holes 1B \1C, and the two standby air inlet holes 1B \1C can be sealed by using screws when not used.

When the textile fabric is adsorbed by the invention, the airflow 8 firstly enters the energy-saving device 6 through the main air inlet 1A, enters the fluid channel tube 9 through the vent cavity 11, generates the wall attachment effect in the vent cavity 11, introduces the secondary airflow 7 through the wall attachment effect principle, greatly improves the airflow rate and reduces the energy consumption because the flow rate of the introduced secondary airflow 7 is about 10 times of that of the primary airflow, then the airflow 8 directly reaches the non-contact sucker body 3 through the fluid channel tube 9, finally the airflow 8 rapidly flows out through the gap of the blocking foot 4, because of the Bernoulli principle, the airflow speed on the lower surface of the non-contact sucker body 3 is instantly accelerated, the pressure is instantly reduced below the atmospheric pressure, the airflow below the textile fabric is the atmospheric pressure, the pressure difference is formed at this moment, and the textile fabric is rapidly lifted under the action of the pressure difference, because the energy-saving device 6 is used, under the same energy consumption, larger pressure difference can be generated, the adsorption force is greatly improved, the positioning precision of the textile fabric in the transfer process is also greatly improved, and the phenomenon that the fabric slips or falls off in the transfer process can not occur.

The present invention has been described in detail with reference to the embodiments, but the invention is not limited to the embodiments, and the embodiments are only illustrative and not restrictive, and all changes and modifications that come within the scope of the invention are desired to be protected.
