Description

TECHNICAL FIELD

[0001] The utility model relates to a suction nozzle inserting bag device of horizontal welding nozzle machine. BACKGROUND

[0002] Horizontal welding nozzle machine refers to the conveying direction of the packaging bag being on a straight line extending along the horizontal direction. For example, a welding nozzle machine disclosed in a Chinese patent document with the authorized announcement number CN103991591B and the name "a complex soft packaging bag welding nozzle equipment" comprises: a rack, a circulating conveying device arranged on the rack, an automatic nozzle feeding device for orderly feeding nozzles to the next device, a nozzle pushing device installed on the rack for receiving the nozzles conveyed by the automatic nozzle feeding device and feeding the nozzles by two at a time into the circulating conveying device, a bag taking and sleeving device installed on the rack for sleeving one end of a bag body on the nozzles located on the circulating conveying device, a heat sealing device installed on the rack and located on both sides of the circulating conveying device for welding the sleeved nozzles and bag body, a detection device arranged on the rack for detecting whether the bag body is inclined relative to the nozzles, and a collecting device for collecting qualified products and unqualified products respectively, which is arranged on the rack and located on both sides of the circulating conveying device.

[0003] However, the applicant finds that the above-mentioned welding nozzle machine has an unreasonable structure, so the circulating conveying device thereof is improved, and the original equipment is replaced by conventional technology to improve the working efficiency and reduce the energy consumption. Among them, the suction nozzle inserting bag device is a device used by the welding nozzle machine to insert the suction nozzle into the bag body with the bag opening. The applicant finds that the conventional suction nozzle inserting device has a very low working efficiency, and the suction nozzle inserting device with a higher working efficiency in the prior art has a complex structure, a high price, and a series of problems such as being not suitable for completing multiple suction nozzle bag processing at the same station.

[0004] For example, a nozzle feeding device disclosed in a Chinese patent document with the authorized announcement number CN111572101B and the name "a nozzle feeding device" comprises: a rack, at least two nozzle taking mechanical hands for clamping the nozzles, both of which are movably installed on the rack, each of which has a first working position and a second working position, and a driving mechanism for driving the nozzle taking mechanical hands to move between the first working position and the second working position. This technology has the disadvantages of complex structure, large space occupation, and being not suitable for completing multiple nozzle bag processing at the same station. UTILITY MODEL CONTENTS

[0005] The utility model aims at providing a suction nozzle inserting bag device of horizontal welding nozzle machine, which occupies a small space and can quickly and accurately feed the nozzles. The technical scheme adopted is as follows:

[0006] The application discloses a suction nozzle inserting bag device of a horizontal welding nozzle machine, which is characterized by comprising a suction nozzle conveying unit, a single suction nozzle transferring unit, a single suction nozzle pushing unit and a bag inserting unit. The suction nozzle conveying unit comprises a suction nozzle conveying groove and a conveying belt. The suction nozzle conveying groove is provided with an inlet connected with a vibrating disc conveying groove and an outlet connected with a bag inserting channel.

Compared with the liftable nozzle positioning groove with an upper opening, the nozzle positioning hole formed by the liftable nozzle positioning groove and the groove cover plate can limit the nozzle in 360 degrees, effectively preventing the nozzle from moving upwards.

[0009] The present application has the advantages that the nozzle is conveyed by the nozzle conveying unit, the single nozzle is transferred to the bag inserting unit by the single nozzle transferring unit, and the nozzle is pushed out by the single nozzle pushing unit to complete the bag inserting work, so that the space occupied by the equipment can be effectively reduced, the bag inserting work can be quickly and accurately completed, the work efficiency is high, and the energy consumption is low.
