The object of the present invention is to provide a kind of paper suction pipes to bend, cuts the process of angle.This paper suction pipe bending is cut tiltedly
The process of mouth enables to paper suction pipe bending difficulty to reduce, and bending part is not easy to break.
Goal of the invention of the invention is achieved through the following technical solutions:
1, a kind of paper suction pipe bends, cuts the process of angle, includes the following steps:
Step 1: the conveying of paper suction pipe；
Step 2: paper suction pipe impression, creasing method is impression knife and the round geosynclinal block being fixedly connected with impression knife is impression component

The bending of toilet tissue suction pipe.
Paper suction pipe in step 3 cuts angle, belongs to direct beveling in the prior art so that paper pipette tip formed it is oblique
Notch.Final rewinding.
In actual production work, paper suction pipe is found when being made, and intensity is higher, Indentation Process difficulty and impression effect
It is unobvious.When impression dynamics is higher than 300-400N, paper suction pipe is easy to happen whole deformation, causes paper suction pipe quality bad；When
When impression dynamics is lower than 100N, the impression on paper suction pipe surface is unobvious, so that paper suction pipe bending difficulty and effect are poor.To solve
The above problem, the present invention are handled paper suction pipe using following technique:
Step 2.1 is provided between the step 2 and step 3, the step 2.1 is the preheating of paper suction pipe, using heating tube to paper
Suction pipe bending region is preheated, and 100-120 DEG C of preheating temperature, preheating time 5-10s.
Step 2.2 is provided between the step 2 and step 3, the step 2.2 is the hardening by cooling of paper suction pipe, utilizes spray
Tracheae to paper suction pipe bending region cool down, cooling temperature be 20-25 DEG C, cooling time 3.2-3.6s.
Paper suction pipe is preheated, reason is that the burning point of paper suction pipe is 130-250 DEG C, is higher than paper suction pipe under certain temperature
Interior fibre structure can rupture, so that paper suction pipe softness number increases, facilitate carry out impression.When between paper suction pipe and heating tube
When state in relative movement, the temperature highest of heating tube can reach 400 DEG C, and preheating temperature described above is only needle
Preheating temperature when relative static conditions is in paper suction pipe and heating tube.
Paper suction pipe bending region is preheated using heating tube, preheating temperature is 100-120 DEG C.Preheating temperature is higher
When, softening rate is fast, improves efficiency, and when preheating temperature is lower, softening rate is slow, and efficiency is lower, but softening degree is lower,
Impression effect is preferable.
Wherein, the preheating temperature is 113 DEG C, and through overtesting, it is found that when preheating temperature is 113 DEG C, softness number is suitable
Preferably, and softening rate is suitable, and neither influence working efficiency nor affects on impression effect.
Wherein, preheating time 7.4s, through overtesting, not too big influence paper suction pipe itself when preheating time is 7.4s
Physical property and chemical property.Extend preheating temperature, will lead to paper suction pipe and be denaturalized, so that paper suction pipe quality is bad.
After preheat, usually paper suction pipe is waited to be cooled to room temperature down, it is however generally that, by the preheating of short time, paper is inhaled
The temperature of pipe bending part is 75-82 DEG C.At this time the technical issues of is to cool down to paper suction pipe.
Paper suction pipe is cooling to be usually used what method cooling under room temperature carried out, cools down at normal temperature, the bending of paper suction pipe
Efficiency is lower, needs to guarantee that the temperature of paper suction pipe is reduced to room temperature and can guarantee that paper suction pipe enters next step process and will not send out
Raw processing denaturation, efficiency are lower.Meanwhile during paper suction pipe gradually cools down, the fibrous layer inside paper suction pipe is after the cooling period still
So the structure after denaturation is kept to cause paper suction pipe to be easily damaged so that the hardness of paper suction pipe is lower, service life lower problem.
To solve the above-mentioned problems, paper suction pipe bending region is cooled down using air jet pipe, cooling temperature 20-25
℃.Paper suction pipe is cooled down in a short time using quick flow, so that the fibrous layer inside paper suction pipe is in lower temperature
It is lower to bounce back, it is further broken to reduce fibrous layer, ensure that the hardness of paper suction pipe to a certain extent, to prevent paper
Suction pipe fractures and deforms in following process.
Through overtesting, cooling temperature is 23.6 DEG C, and when cooling time is 3.3s, cooling effect is best, and efficiency is higher.
The reason is that, cooling temperature is 23.6 degree 25 DEG C of room temperatures of comparing, temperature is slightly lower, so that fiber has the trend to bounce back,
And the room temperature that compares, trend is more obvious, ensure that the hardness of paper suction pipe.When higher than 23.6 DEG C, the effect of retraction is slightly worse,
Efficiency reduces.When lower than 23.6 DEG C, retraction speed is very fast, so that the trend of fiber retraction is excessive, fibrous layer is caused to be easy hair
Raw fracture.Fiber fault rupture directly affects the hardness of fibrous layer, will lead to fibrous layer and easily deforms in following process.
It is compared to above-mentioned pre-heating mean, another new process set forth below, it is characterised in that:
Step 2.1 is provided between the step 2 and step 3, the step 2.1 is paper suction pipe stepping stretching, utilizes one group of pressure
After trace component is to paper suction pipe impression, pulling force is applied to paper suction pipe both ends by stepper motor.
The pulling force size is 107.5N-184.2N, and the force time is 0.2-0.6s, is repeated the above steps, an impression
A corresponding stepping stretches.
Be compared to pre-heating mean, the characteristics of this method technique, is, without being heated, without control temperature and when
Between good bending effect can be realized.Paper suction pipe both ends are fixed, while being applied by stepper motor to paper suction pipe both ends and being drawn
Power.When paper suction pipe is scored, the stress of paper suction pipe recess is more concentrated, and excessive stress is easy to cause paper suction pipe recess
Difficulty of processing increase, and paper suction pipe internal structure is easy to cause to be destroyed, influences the intensity of paper suction pipe.Therefore, for above-mentioned
Problem realizes a kind of solution for effectively changing stress and concentrating.
After carrying out first time impression to paper suction pipe by one group of impression component, stepper motor applies paper suction pipe both ends smaller
Pulling force, and the step-length very little of stepper motor, the force time is the short time less than 1s.After carrying out an impression, depressed section
It will appear problem of stress concentration, at this point, stepper motor applies pulling force, so that internal fiber is stretched on microcosmic, surface variation
It is smaller.Meanwhile so that the distance between internal fiber molecule increases, reduction stress is concentrated.Next above step is repeated, so that
Stress is not at the problem of concentrations, to prevent the collapse of paper suction pipe internal structure from destroying, guarantees the intensity of paper suction pipe.Together
When, enabling to the intermolecular distance of paper suction pipe bending part to keep is suitable for, so that the difficulty of paper suction pipe bending reduces, guaranteeing that paper is inhaled
The using effect of pipe.
Through overtesting, pulling force size is 107.5N-184.2N, and when the force time is 0.2-0.6s, effect is best.At this
In a weight range, paper suction pipe will not be caused directly to be pulled off since pulling force is excessive, meanwhile, also it can prevent pulling force is too small to cause
Internal stress cannot achieve the effect that dispersion.The force time is shorter, so that paper suction pipe inner fibrous layer will not be under external force
Fracture prevents the intensity and effect that influence paper suction pipe.
Working efficiency when in order to solve the problems, such as to pull above by stepper motor is lower.The main producing cause of its problem
Be: each impression requires a stepper motor and pulls, and can only handle a paper suction pipe every time, largely effects on paper suction pipe
Production efficiency, to influence the production of paper suction pipe.Therefore, to solve the above-mentioned problems, the present invention provides following technical schemes:
Step 2.1 is provided between the step 2 and step 3, the step 2.1 is paper suction mold impression, and circular mode is arranged
Tool group, circular die group include multiple impression components, and impression component is set in circular die group, and paper suction pipe enters circular mode
After tool group, circular die group closes up the impression straight forming so that paper suction pipe bending part.
Multiple impression components that circular die group includes can carry out impression to paper suction pipe within the same time, so that multiple
Impression is completed at the same time, and guarantees working efficiency.Those skilled in the art are directed to the technical problem of working efficiency deficiency, it is however generally that meeting
It is carried out using multiple groups stepper motor, and the production cost produced in this way is higher, and substantially there is no solve production efficiency
Low problem.Therefore, the present invention can be realized the production efficiency of single paper suction pipe bending impression by using circular die group
It is higher, substantially realize paper suction pipe improving productivity.For the production method, due to using the circular die group side of closing up
Formula carries out impression, a possibility that reducing maloperation, also, carrying out impression simultaneously can effectively prevent stress to concentrate, reach compared with
Good impression effect.
The step 3 replaces with step 3.1, and the step 3.1 is that paper suction pipe circular die group cuts angle, using in circle
Inclined cutter is arranged in mold group end, directly cuts angle during impression, cuts angle and carries out simultaneously with bending impression.
In order to solve the problems, such as subsequent to need to increase impression knife and carry out cutting angle.The present invention is utilized and is set in circular die group
Inclined cutter is set, directly angular cut during carrying out impression, further improve production efficiency, so that the life of single paper suction pipe
It is higher to produce efficiency.
Be compared to the process of conventional bending part impression in the prior art, production efficiency of the invention slightly under
Drop, right goose improves the quality of bending part, so that bending part is not easy to break or damaged, guarantees the quality of paper suction pipe, and not
It is excessive to will lead to production efficiency reduction.
In conclusion the invention has the following advantages:
1, first innovative point of the invention is, in the prior art, general indentation process is directly to be rolled using impression knife
Direct impression on paper suction pipe under dynamic state, production efficiency is higher, but finds after actual use, bending difficulty compared with
Greatly, and bending part it is second-rate, be easier to occur damaged.To solve this technical problem, the invention discloses a kind of preheating sides
The production technology of formula impression.This production technology takes full advantage of the property of fiber part pre- thermal softening before burning point in paper suction pipe
Matter both will not significantly influence the hardness of paper suction pipe it is also possible that impression difficulty so that reaching more suitable preheating temperature
It reduces.Meanwhile after preheating, conventional production practices are usually to wait natural cooling, and the present invention uses a kind of rapid cooling
Method, this method cool down paper suction pipe using the gas for being slightly less than room temperature.Excessively low temperature will lead to paper suction pipe retraction it is excessive,
So that bending part is damaged, temperature is excessively high to will affect cooling effect.By sufficiently testing, the present invention proposes the cooling optimized the most
Temperature and cooling time, so that the cooling effect of paper suction pipe is best and the physics and chemical property that will not influence paper suction pipe itself,
And the production efficiency of paper suction pipe is improved, it solves due to new problem caused by preheating.
2, second innovative point of the invention is, in order to solve problem of stress concentration in process of production, prevents from answering
Power concentration causes paper suction pipe difficulty of processing to increase, and paper suction pipe later strength goes wrong.Those skilled in the art ask in face of above-mentioned
The basic skills usually concentrated using stress is solved: topic guarantees that there are certain gaps between two impressions, so that answering
Power will not be concentrated excessively, guarantee mutually separated between impression.The present invention corresponds to solution in the prior art, proposes more excellent
Good settling mode pulls paper suction pipe using stepper motor, so that each impression of paper suction pipe corresponds to one-off drawing, answers to reduce
Power is concentrated, and guarantees that the physical property of paper suction pipe will not vary widely.It is found after centainly testing, pulling force size and force
Time one, periodically its effect was best.Within this range, the intensity and effect of paper suction pipe reach most preferably, and effect is best.
3, third innovative point of the invention is, in order to solve asking for caused inefficiency in paper suction pipe production process
It inscribes, those skilled in the art propose a kind of mode for rolling impression, directly utilize impression knife, paper suction pipe is by rolling movement
Mode is transported forward, thus achieve the purpose that impression during transportation, and the impression that this mode extrudes, it is second-rate,
So that the difficulty of paper suction pipe bending is larger, and it is easy to cause paper suction pipe damaged.The invention proposes a kind of more excellent method,
A kind of circular die group is designed, is enabled and is reached intensive impression simultaneously when paper suction pipe enters in circular die group and cut
The mode of angle so that circular die group can be improved the production efficiency of paper suction pipe, and impression effect and cut angle effect compared with
It is good.

When cumulative big, stretch bending strength is gradually increased, and when being more than above-mentioned numerical value, stretch bending strength is gradually reduced.Therefore, pulling force size is
When 150.8N, when the force time is 0.57s, effect is best.Under this pulling force, paper suction pipe will not be caused since pulling force is excessive
Directly it is pulled off, meanwhile, it can also prevent pulling force is too small to cause internal stress that cannot achieve the effect that dispersion.Exert a force the time compared with
It is short, so that paper suction pipe inner fibrous layer will not be broken under external force, prevent the intensity and effect that influence paper suction pipe.More than this
