Description

TECHNICAL FIELD

[0001] The utility model relates to a horizontal welding nozzle machine with reasonable structure. BACKGROUND

[0002] The 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" includes: a rack, which is provided with a circulating conveying device; an automatic feeding nozzle device, which is used for feeding the nozzles into the next device in order; a nozzle pushing device, which is installed on the rack and is used for receiving the nozzles conveyed by the automatic feeding nozzle device and feeding the nozzles into the circulating conveying device by two at a time; a bag taking and sleeving device, which is installed on the rack and is used for sleeving one end of the bag body on the nozzles located on the circulating conveying device; a heat sealing device, which is installed on the rack and is located on both sides of the circulating conveying device and is used for welding the sleeved nozzles and bag body; a detection device, which is provided on the rack and is used for detecting whether the bag body is inclined relative to the nozzles; and a collecting device, which is used for collecting the qualified products and unqualified products respectively, is provided on the rack and is 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. Since the bag body is set in an inverted state, in order to ensure the stability of the conveying and the accuracy of the bag sleeving, the working efficiency of the bag taking and sleeving device is difficult to improve, and the conveying speed of the circulating conveying device is difficult to improve. Therefore, although the working efficiency of the heat sealing device and the collecting device can be improved, they need to wait for the bag taking and sleeving device and the circulating conveying device to complete the work, which makes it difficult to improve the working efficiency of the whole machine and cannot meet the increasing production demand. The applicant finds that even if the bag body is changed from the inverted state to the lying state by using the conventional horizontal conveying mechanism and the nozzle insertion bag equipment is used to replace the bag taking and sleeving device, and the other devices are improved accordingly, due to the unreasonable structure and the need for a large number of driving devices to drive different devices respectively, the actions of the devices are difficult to coordinate, the cooperation is difficult, the energy consumption is excessive, and the working efficiency is also difficult to improve.

[0043] 1. The bag taking mechanism 2 takes out two bags to the bag taking station A and keeps the bags in a flat state. The horizontal clamping and conveying unit 301 clamps and takes away the two bags from the bag taking station A.

[0044] 2. The horizontal clamping and conveying unit 301 conveys the two bags to the bag opening station B. The temporary clamping unit clamps the two bags. The horizontal clamping and conveying unit 301 returns. The bag opening mechanism 4 opens the bag mouths of the two bags. The horizontal clamping and conveying unit 301 clamps the two bags with opened bag mouths. The temporary clamping unit releases the two bags.

[0045] 3. The horizontal clamping and conveying unit 301 conveys the two bags with opened bag mouths to the insertion station C. The temporary clamping unit clamps the two bags with opened bag mouths. The horizontal clamping and conveying unit 301 makes return motion. The nozzle and bag insertion mechanism 5 inserts two nozzles into the two bags with opened bag mouths respectively. The horizontal clamping and conveying unit 301 clamps the two bags. The heat sealing mechanism 6 corresponding to the insertion station C performs primary heat sealing (i.e. point sealing) on them (the nozzle and bag in the insertion state). The temporary clamping unit releases the two bags.

[0046] 4. The horizontal clamping and conveying unit 301 conveys the two nozzle bag semi-finished products to the first heat sealing temporary parking station D. The temporary clamping unit clamps the two bags. The horizontal clamping and conveying unit 301 makes return motion.
