Described pin group becomes hexagonal prism to form by 2 cross sections, is describedly vertically arranged in above back up pad.
Beneficial effect
Advantage of the present invention is as follows:
1) in the present invention, each test cell all changes horizontally disposed design into, reduces the placement requirement for horizontality of device, is conducive to enterprise practical and uses.And the motion of support plate changes tangential movement into, and by motor by realizing under the drive of offset cam and connecting rod and pin, eliminate in former utility model and be arranged vertically design owing to adopting, when the frequency that moves up and down of support plate is very fast, support plate and cam there will be the impact departing from and do not catch up with the phenomenon of camming movement and the weight of support plate and cause to the easy motion of test cell.
2) because each test cell all changes horizontally disposed design into, and yarn is walked around pulley jib by chain and weight, eliminate former being arranged vertically in design because yarn hangs vertically, the weight 4 played below sample can swing back and forth in test process, affects the drawback of sample tension stability.
3) have employed weight in the present invention to fall, block the light between optoelectronic switch, counter is made to stop counting, thus the principle of load action period number when making counter corresponding to this test cell automatically write down yarn breakage suffered by yarn, overcome because weight during each yarn breakage directly drops on proximity switch in prior art, the defect larger to the life damage of proximity switch.
4) in the present invention, weight 4 weight range has been increased to 70-140 grammes per square metre, changes weight 4 weight range 10-60 grammes per square metre in the former patent of utility model, can not meet the deficiency of test request when chemical fiber yarn very well.

Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
As shown in Figures 1 to 3, a kind of horizontal sizing wear resistant system safety testing device, comprises frame 1, rack-mounted counter 9, two guide rails 12 described frame 1 are equipped with, 12 ˊ and cylindrical yarn folder 2, described guide rail 12, 12 ˊ are arranged in frame 1, described guide rail 12, the frame 1 of 12 ˊ one end is installed cylindrical yarn folder 2, the other end is installing rotating shaft 7 near the position of frame, and in described rotating shaft 7, corresponding circle cylindricality yarn presss from both sides 2 positions installation pulleys 8, described guide rail 12, back up pad 6 12 ˊ is equipped with, described back up pad 6 and guide rail 12, become sliding pair between 12 ˊ, photoelectric sensor 15 is equipped with in described back up pad 6 side, and described photoelectric sensor 15 is connected with counter 9, counter 9 according to the signal record back up pad 6 of photoelectric sensor 15 along guide rail 12, 12 ˊ to-and-fro movement number of times, described back up pad 6 two ends are with dragging axle 19, 19 ˊ connect power system, and the position of described back up pad 6 corresponding circle cylindricality yarn folder 2 and pulley 8 is provided with friction pin group 5, and described yarn 3 one end is connected on cylindrical yarn folder 2, middle part is wound in friction pin group 5, the other end connects chain 16, and described chain 16 is walked around pulley 8 and hung a weight 4 downwards, below described weight 4, optoelectronic switch 17 is housed, 17 ˊ, described optoelectronic switch 17, 17 ˊ are connected with counter 9, when rub in friction pin group 5 weight 4 of having no progeny of yarn 3 drops through optoelectronic switch 17, 17 ˊ make counter 9 record when yarn 3 ruptures back up pad along guide rail to-and-fro movement number of times, as yarn abrasion number of times.
Described back up pad 6 is furnished with the cylindrical yarn folder 2 of 1 to 15 group, pulley 8, chain 16 and weight 4, for testing many group yarns 3 simultaneously.
Described back up pad 6 is furnished with 3 groups of cylindrical yarn folders 2, pulley 8, chain 16 and weights 4, for testing many group yarns 3 simultaneously.
Described power system comprises motor 13, described motor 13 two ends output shaft 10 connecting eccentric wheel 14,14 ˊ, and described eccentric wheel 14,14 ˊ connects connecting rod 18,18 ˊ, and described connecting rod 18, the 18 ˊ other end is in the hinge connection with dragging axle 19,19 ˊ.
Described weight 4 weight is 70-140 gram.
Be connected with linear bearing 11,11 ˊ between described back up pad 6 with guide rail 12,12 ˊ.
Described friction pin group 5 is made up of the rectangular parallelepiped of 4 cross section quadrates, the orthogonal array way of described rectangular parallelepiped is vertically arranged in above back up pad 6, and described yarn 3 passes again after penetrating intersection respectively outside two rectangular parallelepipeds pressing from both sides 2 sides near cylindrical yarn by two and connects chain 16 after crossing outside two rectangular parallelepipeds near pulley 8 side.
Described pin group 5 becomes hexagonal prism to form by 2 cross sections, is describedly vertically arranged in above back up pad 6.
When reality uses along with friction pin group 5 and the friction of yarn 3, yarn rubs disconnected, weight 4 falls due to broken yarn, then optoelectronic switch 17 becomes off-state, counter 9 stops counting, and the number of times of support plate 6 bilateral reciprocation when recording this test cell yarn breakage, this test result directly can reflect the anti-wear performance of textile mills' sizing.The device of this invention is specially adapted to only can provide during the sizing sample of 1-2 rice in textile mills carry out anti-wear performance test to sizing sample, and test is more reliable and stable.
