Material cutting device of rubber band machine

Abstract

The invention discloses a material cutting device of a rubber band machine. A feeding and fixing support comprises a support plate, and a left connecting plate and a right connecting plate arranged ontwo sides of the lower end surface of the support plate; an upper cutter group is arranged at the lower end of the support plate and is an ultrasonic cutter group; a driving mechanism comprises a driving air cylinder and a guiding pillar connected with the upper cutter group and penetrating through the support plate, and can drive the upper cutter group to displace up and down; a lower cutter group is arranged at the lower end of the upper cutter group in a matching way; one end of the lower cutter group is connected with the left connecting plate; and the other end of the lower cutter groupis connected with an adjustable position of the right connecting plate. The material cutting device of the rubber band machine provided by the invention adopts the driving air cylinder and the guidingpillar for driving the ultrasonic cutter to cut a rubber band, and is simple in overall driving manner, good in stability, and excellent in effect on obtaining a finished product through ultrasonic cutting; the overall material cutting device is small in size and low in cost so as to adapt to the overall assembling of the rubber band machine; and in addition, through designing the lower cutter group, the left connecting plate and the right connecting plate, a cutting angle and a cutting position can be conveniently adjusted, so that the material cutting device is applicable to the requirements of different cutting environments.

Description

technical field [0001] The invention relates to the field of rubber band production equipment, in particular to a material cutting device for a rubber band machine. Background technique [0002] The production of elastic rings, the usual production process is to use bundled or rolled elastic bands as raw materials, cut and sewed into loops in sections; in this production process, manual or multiple stand-alone machines with different functions are usually used To complete together, during the production of elastic bands such as underwear elastic bands, the elastic bands need to be cut and cut according to the stated size, and the cutting device of the existing elastic machine, such as the Chinese invention patent with the patent application number 201621273384.5, discloses A material cutting device for a rubber band machine, which uses a drive mechanism composed of a drive motor, a transmission gear combination, and a transmission shaft to drive a cutter that is heated and c...

[0002] The production of elastic rings, the usual production process is to use bundled or rolled elastic bands as raw materials, cut and sewed into loops in sections; in this production process, manual or multiple stand-alone machines with different functions are usually used To complete together, during the production of elastic bands such as underwear elastic bands, the elastic bands need to be cut and cut according to the stated size, and the cutting device of the existing elastic machine, such as the Chinese invention patent with the patent application number 201621273384.5, discloses A material cutting device for a rubber band machine, which uses a drive mechanism composed of a drive motor, a transmission gear combination, and a transmission shaft to drive a cutter that is heated and cut by a heating tube to perform material cutting operations on rubber bands, although some It solves the problem of low degree of automation and low efficiency of rubber band machine cutting, but due to the hot cutting of the heating tube, there are still problems that affect the overall effect of the rubber band, such as blackening and deformation of the rubber band cut, and the overall drive The structure is complex and the transmission is slow, so that the size after cutting cannot be completely uniform. The stability and production efficiency still need to be further improved.
