Description

Technical Field

[0001] The utility model relates to the technical field of automatic packaging equipment, in particular to a belt-inserting and heat-sealing device for a handle belt of a mesh bag. Background Art

[0002] Traditional packaging bags are usually made of composite film, which has a certain hardness due to its unique material. Before filling the bag with materials, we usually open the bag first so that we can put the items in it smoothly. However, when it comes to fruit and vegetable materials such as oranges, lemons, potatoes, etc., if composite film is used for packaging, we will find that its ventilation effect is not satisfactory.

[0003] In order to solve this problem, cylindrical mesh bags specially used for packaging fruits and vegetables have gradually appeared on the market. The bag body design of this cylindrical mesh bag is very unique. It consists of two parts: a cylindrical mesh film and a sheet-type composite film. The inside of the cylindrical mesh film is a space for placing fruits and vegetables, while the sheet-type composite film is attached to the outer part of the mesh film, thus forming the packaging mesh bag we see. This design not only ensures the air permeability of fruits and vegetables, but also makes the entire packaging look more beautiful and practical.

[0004] In order to improve packaging efficiency, some mechanical equipment specially used for mesh bag packaging has appeared on the market. These mesh bag packaging machines usually include multiple components such as bag making mechanism, transfer mechanism, loading mechanism and bag sealing mechanism. They can automatically complete the entire process from bag making to loading and sealing, greatly improving production efficiency. However, in the existing mesh bag packaging machines, the mechanism of sealing the bag opening is relatively simple, and can only seal the mesh bag opening. In this way, the sealed mesh bag has no handle for users to carry, making it uncomfortable for users to take the mesh bag filled with fruits and vegetables. Utility Model Content

[0043] In the previous process, the mesh bag filled with materials is fed into the mounting frame 1 from the feeding side, and the mesh bag is poked open from the middle by the poking knife 6. Then, the mesh bag is continued to be moved between the two groups of heat-sealing components 2 of the mounting frame 1, and is separated to both sides by the poking knife 6 when entering. Then, the membrane sheets on both sides of the separated mesh bag cannot be stuck together due to the separation effect of the mesh bag partition plate 8. When the mesh bag enters the mounting frame 1 at the end position of the mesh bag in the moving direction, the air blowing nozzle 7 blows air to the end of the mesh bag to blow back the mesh bag poked out by the poking knife 6. When the above steps are performed, the handle belt clamping cylinder 43 clamps the handle belt from the clamping position, and then the handle belt driving cylinder drives the handle belt clamping cylinder 43 to move along the handle belt guide shaft. The handle belt is pulled out automatically; after being stretched to a specified length, the two vacuum suction cups 51 of the suction and insertion belt assembly 5 respectively suck the two ends of the handle belt; the cutting drive member 44 drives the handle belt cutter 45 to approach the handle belt to cut the handle belt; after the net bag moves to the heat sealing position, the first lifting plate 531 of the lifting drive member 53 is driven downward by the first lifting cylinder 532, thereby driving the insertion belt gear 552 to move downward. Due to the existence of the spring 555, the second lifting plate 554 cannot move downward with the first lifting plate 531 (the first lifting plate 531 continues to move downward, and the upper end of the limit rod 556 abuts against the upper end of the second lifting plate 554. At this time, the second lifting plate 554 will move downward synchronously with the first lifting plate 531.), and the insertion belt rack 5 53 and the belt inserting gear 552 are relatively displaced, and the belt inserting gear 552 rotates to drive the belt inserting turntable 551 to rotate, that is, to drive the vacuum suction cup to deviate from the rotation axis of the belt inserting turntable 551 to rotate, and the two belt inserting turntables 551 rotate in opposite directions to achieve the bending of the handle belt. At the same time, the air blowing pipe 56 blows air, and the first lifting plate 531 continues to move downward to insert the two ends of the handle belt between the diaphragms; then, the vacuum suction cup 51 releases the handle belt, and the lifting drive member 53 drives the first lifting plate 531 to move in the opposite direction to reset, and the second lifting plate 554 moves up to reset, and the belt inserting rack 553 is also reset, thereby realizing the driving of the vacuum suction cup 51 to rotate in the opposite direction to reset, waiting for the next suction of the handle belt; then, The two mesh bag opening clamping cylinders 31 respectively drive the two baffles 21 to clamp the mesh bag, and the heat sealing cylinder 32 drives the two sealers 22 to approach each other and pass through the first and second make way holes 211 to contact the mesh bag (the heat sealing position is on the mesh bag portion on the lower side of the mesh bag partition plate 8), heat-seal the mesh bag opening, and cut a handle hole on the mesh bag through the heat sealing cutter 221, and the easy-tear cutter 23 also pokes an easy-tear cut on the mesh bag; then the heat sealing component 2 and the heat sealing drive component 3 can be reset to wait for the next heat sealing (the sealer 22 is reset first, and the mesh bag will not stick to the sealer 22 when blocked by the baffle 21, and the baffle 21 can also be provided with blowing holes and hot air outlets to cool the mesh bag), and the heat-sealed mesh bag can be sent out.
