CN201395658Y - Novel under screen structure - Google Patents

Abstract

The utility model discloses a novel under screen structure, including left arc frame, right arc frame and many dirt sticks, each dirt stick one end is fixed on left arc frame, and the other end is fixed on right arc frame, and all parallel evenly distributed of dirt sticks are the fretwork district between two adjacent dirt sticks, and the characteristic is the section of dirt stick is oval-shaped. The utility model discloses in, design into oval type structure with the section of dirt stick, change the round structure that prior art dirt stick used conventionally, the end leakage of oval type section structure dirt stick is taken to the experience demonstration, can guide according to the reason at the produced air current of operation process at the end leakage department to the cylinder, and the main performance increases in the stationary flow district, flows in succession comparatively smoothly etc. is favorable to the end leakage to the support of cotton net and the row that leaks of emerging debris (matter) very much.

Description

Novel leakage bottom structure

Technical field

The utility model relates to the leakage bottom of using below the cylinder in the carding machine and divides, and is relevant with the leakage bottom structure especially.

Background technology

In the existing carding machine (equipment), be used for being commonly referred at the bottom of the big leakage at the bottom of the leakage of cylinder below.Role mainly contains two at the bottom of the above-mentioned big leakage: the one, web is carried out holding effectively, and the 2nd, make the foreign material (matter) that appear in one's mind in the web fall to getting rid of from the hollow out of leaking the end.A kind of main flow leakage end, comprise left arc frame, right arc frame and many dirt rods, and each dirt rod one end is fixed on the left arc frame, and the other end is fixed on the right arc frame, is vacancy section between adjacent two dirt rods, and the section of above-mentioned each dirt rod is round.The dirt rod of finding above-mentioned section structure in practice can produce adverse influence to air-flow, show that mainly the turbulent region is many, and it is intermittently not smooth to flow etc., this unfavorable also can feed through to leak the end to the holding of web and appear aspect such as omitting in printing of foreign material (matter) in one's mind.Therefore, await further to improve at the bottom of this leakage of taking above-mentioned section structure dirt rod.

The utility model content

The utility model is to solve the above-mentioned technological deficiency that prior art exists, and a kind of novel leakage bottom structure is provided.

Its technical solution is:

A kind of novel leakage bottom structure comprises left arc frame, right arc frame and many dirt rods, and each dirt rod one end is fixed on the left arc frame, the other end is fixed on the right arc frame, the parallel even distribution of all dirt rods is a vacancy section between adjacent two dirt rods, and the section of above-mentioned dirt rod is an ellipse.

Distance between the above-mentioned adjacent dirt rod is 2～3cm.

In the utility model, the Section Design of dirt rod is become oval structure, change the usual round structure that uses of prior art dirt rod, empirical tests is taked at the bottom of the leakage of ellipse section structure dirt rod, can make the best use of the situation at the operation process air-flow that Lou bottom produced of passing through to cylinder, show that mainly the current stabilization district increases, it is comparatively smooth and easy continuously to flow etc., is particularly conducive to the end Lou to the holding of web and appear omitting in printing of foreign material (matter) in one's mind.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and the specific embodiments:

Fig. 1 is the structural principle schematic diagram of a kind of embodiment of the utility model.

Fig. 2 is the side-looking structural representation of Fig. 1 mode.

Fig. 3 is the sectional drawing of the single dirt rod in Fig. 1 mode.

The specific embodiment

In conjunction with Fig. 1, Fig. 2 and Fig. 3, a kind of novel leakage bottom structure comprises left arc frame (left side iron) 1, right arc frame (the right iron) 2 and many dirt rods 3.The section of each dirt rod 3 is an ellipse, one end of dirt rod 3 is fixed on the left arc frame 1 with welding method, the other end also is fixed on the right arc frame 2 with welding method, all dirt rod 3 parallel being evenly distributed between left arc frame 1 and the right arc frame 2, distance between the adjacent two dirt rods 3 is 2cm or 3cm, is vacancy section 4 between adjacent two dirt rods 3.

Claims (2)

1, a kind of novel leakage bottom structure, comprise left arc frame, right arc frame and many dirt rods, each dirt rod one end is fixed on the left arc frame, the other end is fixed on the right arc frame, the parallel even distribution of all dirt rods, between adjacent two dirt rods is vacancy section, it is characterized in that: the section of described dirt rod is an ellipse.

2, novel leakage bottom structure according to claim 1 is characterized in that: the distance between the described adjacent dirt rod is 2～3cm.
