Problems solved by technology

[0002] At present, the lifting device in the automatic liquid-based thin-layer cell film maker is mostly driven by a motor, and the tooth groove is mostly a square tooth groove. The friction coefficient is large during transmission, and the lifting and sliding are not smooth, while the circular rack is prone to rotation. It is difficult to ensure a straight rise or fall, which affects the work efficiency of the film maker

Embodiment Construction

[0026] Below in conjunction with accompanying drawing, the present invention will be further described:

[0027] Such as Figure 1-8 As shown, a lifting mechanism for an automatic liquid-based thin-layer cell film maker includes a motor 2 arranged on the installation module 1, a gear 3 connected to the output end of the motor 2, and a lifting rack 4 meshing with the gear 3. The lifting The teeth on the rack 4 are arc-shaped teeth, and the arc length of the arc-shaped teeth is at least one-third of the circumferential length of the elevating rack 4 , and the elevating rack 4 is provided with a linear bearing 5 . Correspondingly, there are three groups of balls in the linear bearing 5 , preferably each group of balls is a double row of balls, and more preferably, each group of balls is arranged in a waist shape. The tooth width of lift rack 4 is maximized like this, can maximize the depth of tooth, prevents gear and lift rack from rotating and slipping. Because the conventiona...

Abstract

The invention discloses a lifting mechanism for an automatic liquid-based thin-layer cell preparation machine. The lifting mechanism comprises a motor arranged on a mounting module, a gear connected to the output end of the motor, and a lifting rack engaged with the gear; teeth on the lifting rack are arc-shaped teeth; arc length of the arc-shaped teeth is at least one third circumferential length of the lifting rack; the lifting rack is sleeved by linear bearings; each linear bearing is equipped with three groups of rolling balls; and each group of rolling balls are double-row rolling balls. According to the lifting mechanism disclosed by the invention, the teeth of the transmission rack are the arc-shaped teeth, and each linear bearing used for sleeving is provided with three groups of symmetrical steel balls, so that length of the arc-shaped teeth is maximized and depth of the rack can be maximized, and therefore, the lifting rack does not step out or slip under driving of the gear; during sliding or rotating, the steel balls do not scratch the rack; the lifting rack is positioned and cannot rotate, and only can move up and down, so that the gear is guaranteed to be engaged with the lifting rack; and moreover, a pressing device of the lifting rack guarantees pressing force for linear positioning, and a dyeing needle is precisely calculated located and knocked.

Description

【Technical field】 [0001] The invention relates to a lifting mechanism for an automatic liquid-based thin-layer cell slicer, belonging to the technical field of medical detection equipment. 【Background technique】 [0002] At present, most of the lifting devices in automatic liquid-based thin-layer cell slicers are driven by motors, and the tooth grooves are mostly square tooth grooves. The friction coefficient is large during transmission, and the lifting and sliding are not smooth, while the circular racks are prone to rotation. It is difficult to ensure a straight rise or fall, which affects the work efficiency of the film maker. 【Content of invention】 [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a lifting mechanism for an automatic liquid-based thin-layer cell slicer that can ensure positive engagement, reduce friction, and make the operation smoother. [0004] The present invention is achieved through the f...
