Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sampling machines, in particular to a reflective PP material sampling machine. BACKGROUND

[0002] PP material is polypropylene, which is a non-toxic, odorless, tasteless, milky white high-crystalline polymer, and the density is only 0.90-0.91 g / cm3, which is one of the lightest varieties among all plastics. It is particularly stable to water, and the water absorption rate in water is only 0.01%, and the molecular weight is about 80-150 thousand. The forming property is good, but the shrinkage rate is large (1%-2.5%), and thick-walled products are prone to depression. It is difficult to meet the requirements for some high-precision parts, and the surface gloss of the product is good.

[0003] The existing reflective PP material has a reflective layer on one side and a common layer (i.e. without a reflective layer) on the other side. In the factory test, the afterglow brightness of the reflective layer needs to be detected, that is, a small part (a circular sample) needs to be cut from the whole material for convenient testing. However, the existing sampling method is manual sampling, which is relatively low in efficiency, and manual sampling is easy to damage the sample. CONTENT OF THE UTILITY MODEL

One end of the screw rod is fixedly connected to a pressure plate, and the outer wall of one side of the mounting seat is provided with a driving assembly for driving the threaded sleeve to move.

[0006] The above structure is adopted. The threaded sleeve in the pressing mechanism drives the screw rod to move downward, and the pressure plate moves downward to conveniently cut the PP material on the supporting assembly. The relative height of the pressure plate is conveniently adjusted by the screw rod.

[0007] The bottom inner wall of the mounting seat is fixedly connected with two mounting rods, the threaded sleeve is slidably connected to the outer walls of the two mounting rods, and the top outer wall of the screw rod is fixedly connected with an adjusting knob.

[0008] The above structure is adopted. The sliding track of the threaded sleeve is conveniently limited by the two mounting rods, and the screw rod is conveniently driven to rotate by the adjusting knob.

[0009] The outer wall of the threaded sleeve is fixedly connected with a rack one, the same gear one is rotatably connected with the inner wall of the two sides of the mounting seat, and the gear one and the rack one are meshed with each other.

[0010] With the above structure, the rotation of the gear one drives the rack one to move, and the rack one is directly driven to move when the gear one moves.

[0011] The gear one transmission shaft is connected with the driving assembly, the outer wall of one side of the mounting seat is rotatably connected with a pull rod, and one end of the pull rod transmission shaft is fixedly connected with the gear one.

[0012] With the above structure, the pull rod is provided to directly drive the gear one to rotate manually, so that the position of the pressing plate is adjusted conveniently.

[0013] The driving assembly comprises a driving box fixedly connected with the mounting seat, the inner wall of one side of the driving box is rotatably connected with a gear two, and the gear two is connected with the gear one transmission shaft.

[0014] With the above structure, the gear two is arranged in the driving box, and the gear two and the gear one are coaxially rotated.

[0015] The inner wall of the two sides of the driving box is fixedly connected with two slide rods, and the outer wall of the two slide rods is slidably connected with a rack two meshed with the gear two.

[0016] With the above structure, the slide rods are arranged to limit the sliding track of the rack two, and the rotation of the gear two drives the rack two to move conveniently.

[0017] One end of each of the two slide rods is provided with an external thread, and the two slide rods are screwed with a nut through the external thread, and the outer wall of the two slide rods is sleeved with a spring.

[0018] With the above structure, the position of the nut on the slide rod is adjusted conveniently through the cooperation between the nut and the external thread, and the position of the nut is adjusted to adjust the elastic force of the spring.

[0019] The supporting assembly comprises a base fixedly connected with the mounting seat, the outer wall of the top of the base is fixedly connected with a mounting sleeve, and the inner wall of the bottom of the mounting sleeve is fixedly connected with a supporting ring.

[0020] With the above structure, the mounting sleeve and the supporting ring on the base are arranged to support the PP material to be cut.
