Belt cutting machine

Abstract

The invention relates to a cutting machine, in particular to a belt cutting machine. The belt cutting machine comprises a frame, a driving motor, a transmission mechanism, a cutter device and a feeding device, wherein the driving motor drives the cutter device and the feeding device to work through the transmission mechanism; the feeding device comprises a first feeding wheel, a second feeding wheel and a third feeding wheel which are parallel to one another, an elastic part and the like; at least one of the first, second and third feeding wheels is a driving feeding wheel; the third feeding wheel is pulled or pressed towards the first and second feeding wheels by the elastic part, so that the first and second feeding wheels are matched with the third feeding wheel respectively; and beltsare pressed among the third feeding wheel and the first and second feeding wheels. Compared with the prior art, the scheme of the invention has the advantages that: the driving force of the feeding wheels on the belts is doubled, and the belts are more difficult to slip, so feeding length consistency is ensured; and the third feeding wheel is pulled or pressed towards the first and second feedingwheels by the elastic part, so the gaps among the feeding wheels do not need to be adjusted, which is convenient and reliable.

Description

technical field [0001] The invention relates to a cutting machine, in particular to a tape cutting machine for cutting Velcro, nylon webbing, colored ribbon, elastic band, zipper and other materials in clothing, shoemaking and bag factories. Background technique [0002] The cutting process is widely used in cloth, leather, bags and other industries. Modern people have higher and higher requirements for cutting technology, requiring high precision and high efficiency to cut materials of different lengths. Traditional cutting materials are all through It is inconvenient to operate and the work efficiency is relatively low to complete the cutting task by hand and some simple facility operations. [0003] There are also tape cutting machines that can automatically cut tapes on the market now, and there are various types, such as computer tape cutting machines, steam pressure tape cutting machines, etc., but their prices are expensive, and the computer part is prone to problems....

Problems solved by technology

[0002] The cutting process is widely used in cloth, leather, bag and other industries. Modern people have higher and higher requirements for cutting technology, requiring high precision and high efficiency to cut materials of different lengths, while traditional cutting materials are all through Manual and some simple facility operations to complete the cutting task, the operation is inconvenient, and the work efficiency is relatively low

[0003] There are also tape cutting machines that can automatically cut tapes on the market, and there are many types, such as computer tape cutting machines, steam pressure tape cutting machines, etc., but their prices are expensive, and the computer part is prone to problems.

In order to understand the above problems, the Chinese Utility Model Patent Application No. 200920139397.7 discloses a fillet tape cutting machine. The length is controlled by the feeding device. The feeding device includes a motor, a feeding eccentric wheel, a semicircular gear, a one-way gear and two feeding wheels. The motor drives the feeding eccentric wheel to rotate, and the feeding eccentric wheel drives the semicircular gear to rotate, and the semicircular gear swings back and forth. Drive the one-way gear, the one-way gear can realize one feeding and one stop feeding, the material belt is set between the two feeding wheels, the cutter eccentric wheel drives the cutter connecting rod to move up and down, and a cutter is installed on one end of the cutter connecting rod to cut Cutting materials, this kind of fillet cutting machine has high work efficiency, low cost and is economical and practical. However, the feeding device of this kind of tape cutting machine has poor feeding length consistency, because the material belt depends on the friction between the material belt and the second feeding wheel. The force can be transmitted. When the gap between the feeding wheels is not well adjusted or the feeding wheels are loose, the material belt is easy to slip, which directly affects the consistency of the feeding length.
