Description

Technical Field

[0001] This utility model relates to the field of folding equipment technology, specifically a triangular scarf folding machine. Background Technology

[0002] Triangular bandages are common medical supplies, often used for bandaging. There are many production equipment and methods for them, and they are becoming increasingly mature in the market.

[0003] For example, the triangular bandage folding and packaging integrated machine with national patent publication number CN220130556U has three problems in the production process: (1) The power element used to transfer the obliquely cut triangular scarf is a slide cylinder. The transfer distance is relatively long, which means that the crossbeam used to load the slide cylinder must be long enough. In order to keep the crossbeam and the slide cylinder in a horizontal state, it is necessary to support them at multiple points. The installation and maintenance are relatively complicated. (2) Before the triangular scarf after being cut at an angle is transferred, it is adsorbed by a negative pressure adsorption using an adsorption plate. Since the triangular scarf is made of cloth and has a certain degree of air permeability, in order to prevent external gas from entering the adsorption plate through the triangular scarf during transfer and causing the triangular scarf to detach from the adsorption plate, it is necessary to continuously perform negative pressure suction on the adsorption plate, which consumes a lot of energy.

[0004] Therefore, we have made technical improvements to our existing triangular scarf folding equipment to meet the usage requirements. Utility Model Content

[0016] Compared with the prior art, the beneficial technical effects of this utility model are: (1) This utility model uses a rotary material handling robot to replace the long-stroke slide cylinder and crossbeam structure in the prior art, which greatly shortens the spatial path of material transfer, reduces the overall size and structural complexity of the equipment, and makes installation, debugging and maintenance more convenient.

[0017] (2) The material transfer assembly uses a needle-punched suction cup as the material picking end. This design uses the needle-punching physical method to grab the triangular scarf by penetrating the fabric. This fundamentally overcomes the disadvantage of the traditional negative pressure adsorption which requires continuous high-power suction due to the breathability of the fabric. This not only greatly reduces energy consumption, but also ensures that the triangular scarf will not loosen or fall off during the rotation and transfer process. The transfer process is extremely stable and reliable.

[0018] (3) The entire folding process adopts a multi-step progressive folding design, including edge finishing, second to fifth folding, and first and second folding for material discharge. Each step is completed by the O-belt conveyor and the folding plate. Compared with other types of conveyors, the O-belt conveyor has higher conveying smoothness. The cooperation between each folding mechanism is close and the action sequence is reasonable, ensuring that each fold is accurate and in place. This makes the final folded triangular scarf square compact, neat, and not easy to loosen, which greatly improves the product packaging quality. The entire process is completed automatically and continuously without manual intervention. The parallel design of the double-group material transfer, folding and discharge assembly enables one machine to process two pieces of material at the same time, resulting in high production efficiency.

[0024] In Example 2, the material on the material roller 2, such as a triangular scarf, can be cut into segments of square fabric by the length cutter 9.

[0025] Example 3, a triangular scarf folding machine as described in Example 1, wherein the diagonal cutting mechanism includes a diagonal cutting blade 10 and a telescopic power mechanism II 11; The diagonal cutting blade 10 forms an acute angle with the axis of the material roller 2 and is located directly above the material conveying roller 3, thereby cutting the incoming material at an angle.

It can be a pneumatic cylinder or an electric cylinder. One end of it is fixed to the loading rack 1 at the rear of the telescopic power mechanism I8, and the other end is fixed to the diagonal cutting blade 10, thereby driving the diagonal cutting blade 10 to move up and down.

The rotating arm 14 is fixed on the top side wall of the rotating shaft 13. The rotating arm 14 is a horizontally arranged beam structure. A telescopic mechanism 16 is vertically fixed on the bottom surface of the end of the rotating arm 14 away from the rotating shaft 13.

[0028] In Example 4, replacing the existing guide rail structure with a material handling robot greatly shortens the spatial path of material transfer, reduces the overall size and structural complexity of the equipment, and makes installation, debugging and maintenance easier.

[0029] Example 5, a triangular scarf folding machine as described in Example 1, wherein the edge-finishing folding mechanism includes two edge-finishing shafts 18, two edge-finishing plates 19 and two rotating power mechanisms II 20; Two rotary power mechanisms II20 are fixed at intervals on the frame 5 at the feed end of the transverse conveyor belt 6.

Two edge trimming plates 19 are respectively fixed on the outer circumference of one of the edge trimming shafts 18. The edge trimming plate 19 is an equilateral right-angled triangle plate. The rotating power mechanism II20 drives the edge-collecting shaft 18 to rotate, thereby driving the edge-collecting plate 19 to fold and collect the material at the feed end of the transverse conveyor belt 6.

[0030] In Example 5, when the picking robot picks up the triangular scarf after it has been cut at an angle and places it at the feed end of the transverse conveyor belt 6, the two rotary power mechanisms II 20 simultaneously drive the edge-collecting shaft 18 to rotate. At this time, the edge-collecting shaft 18 rotates 180° in conjunction with the edge-collecting plate 19, thereby folding the triangular scarf into a square shape.

The configuration is such that each time the pusher telescopic power mechanism 37 pushes the material, the telescopic baffle rod 38 moves downward. At this time, it does not block the incoming material. After the pusher telescopic power mechanism 37 returns to its original position, the telescopic baffle rod 38 extends to prevent the material in the discharge channel 36 from blocking the feeding area of ​​the discharge channel 36, that is, the rear end of the longitudinal channel.

[0037] The working principle of the triangular scarf folding machine in Examples 1-10 is as follows: First, the triangular scarf is conveyed by the material conveying roller 3 to the length cutting mechanism, where it is cut into square pieces of fabric. Then, it is cut into two triangular shapes by the diagonal cutting mechanism. At this point, the material handling robot is linked with its needle-punched suction cup 4 to transfer the triangular pieces of fabric to the transverse conveyor belt 6. The edge-folding mechanism then folds the triangular pieces of fabric into small squares. The folded triangular scarf is then conveyed to the lower part of the secondary folding mechanism, where it is folded and conveyed by the secondary folding conveyor belt 23 to the feed end of the longitudinal conveyor belt 7. The folded scarf is then guided into the longitudinal conveyor belt 7 by the folding guide mechanism. After being folded sequentially by the tertiary folding mechanism, the quaternary folding mechanism, the discharge first folding mechanism, and the discharge second folding mechanism, it is finally folded into a small square triangular scarf.
