The following are the complete steps and working principles of the above embodiments:
Before the device is used, a worker firstly ensures the cleaning and good working state of the outer surfaces of a driving press roller 13 and a driven press roller 14, determines that no impurity and no residue exist, then adjusts parameters of the rolling device according to production requirements and film properties, including roller pressure, roller speed, temperature and the like, ensures that the parameters of the rolling device are matched with film preparation requirements, then starts the rolling device, at the moment, a driving motor 12 drives the driving press roller 13 and the driven press roller 14 to keep the driving press roller 13 and the driven press roller 14 to rotate, and at the moment, a film forming main body 15 presses and stretches a film through a rolling area between the driving press roller 13 and the driven press roller 14 to obtain the required thickness and flatness of the film;
When the rolling anti-adhesion mechanism 2 for spraying a solution to prevent the surface of the driven compression roller 14 from adhering with plastic raw materials is specifically used, the driven compression roller 14 rotates for a certain number of times:
As shown in fig. 3, the transmission assembly 25 is integrally formed by combining a driving wheel, a driven wheel and a transmission belt, and the driving wheels in the transmission assembly 25 are symmetrically and fixedly connected to two sides of the driven press roller 14, and the driven wheels are symmetrically and fixedly connected to one ends of the through shafts 24, which are far away from each other, so that when the driven press roller 14 of the device is started by the staff to keep rotating, the driving wheels positioned at two sides of the driven press roller 14 can drive the driven wheels to synchronously rotate through the transmission belt;
As shown in fig. 3 to 5, since the driven wheel in the transmission assembly 25 keeps rotating continuously, and then drives the through shaft 24 fixedly connected with the driven wheel to rotate synchronously, since the through shaft 24 and the extrusion plate 26 form a ball screw structure, and the extrusion plate 26 is initially positioned near one end of the transmission assembly 25, the extrusion plate 26 is driven to move linearly along the upper surface of the partition plate 23 towards the direction of the stirring wheel 27 when the through shaft 24 keeps rotating;
As shown in fig. 5 and 6, since the water-based lubricant is initially stored in both the reservoir 21 and the inside of the syringe 22, and the partition plate 23 divides the inside of the syringe 22 into two parts at equal intervals, specifically, the through shaft 24 is located at the upper half of the inside of the syringe 22, and the delivery hose 28 is located at the lower half of the inside of the syringe 22, when the above-mentioned pressing plate 26 is kept moving straight, the space of the upper half of the inside of the syringe 22 becomes smaller gradually, and the air pressure inside the syringe 22 is continuously increased and is greater than the air pressure outside the syringe 22 at this time, so that the water-based lubricant inside the syringe 22 is gradually discharged from the delivery hose 28 at the lower half of the syringe 22 as the pressing plate 26 is continuously moved, and the discharged water-based lubricant is gradually flowed into the inside of the patch shell 29 and is kept in a wet state, and when the driven pressing roller 14 kept rotating passes through the position of the patch shell 29, the water-based lubricant on the surface of the patch shell 29 is continuously adsorbed on the outer wall thereof, and a layer of the lubricant film is formed;
As shown in fig. 6, when the squeeze plate 26 is moved in reverse reset along with the continuous rotation of the through shaft 24, the air pressure inside the syringe 22 is continuously reduced and smaller than the air pressure outside the syringe 22, so that the water-based lubricant inside the syringe 22 stops being discharged from the lower half portion of the delivery hose 28 of the syringe 22 along with the reverse reset movement of the squeeze plate 26, and because the liquid storage tube 21 and the syringe 22 are communicated, and the liquid storage tube 21 and the delivery hose 28 are both provided with one-way valves, when the water-based lubricant inside the syringe 22 stops being discharged, the liquid storage tube 21 automatically supplements and inputs enough water-based lubricant into the syringe 22 until the water-based lubricant capacity inside the syringe 22 is equal to the initial capacity, and as the through shaft 24 is continuously rotated, the squeeze plate 26 repeatedly moves inside the syringe 22, so that the outer wall of the driven pressure roller 14 is wetted to prevent the phenomenon of adhesion during the rolling, and because the liquid storage tube 21 is made of transparent material as a whole, and the inside of the liquid storage tube 21 is communicated with the continuous liquid pipe, therefore a worker can directly observe and supplement the water-based lubricant inside the liquid storage tube 21 in time;
as shown in fig. 6 and 7, the position of the stirring wheel 27 is specifically located at the boundary between the upper layer and the lower layer inside the syringe 22, and the outlet of the water-based lubricant is inputted into the liquid storage barrel 21, so that the lubricant flowing through the stirring wheel 27 is located in the position of the stirring wheel 27 no matter the lubricant is outputted from the inside of the syringe 22 or the lubricant is supplied into the inside of the syringe 22 by the liquid storage barrel 21, and the stirring wheel 27 is fixedly connected with the penetrating shaft 24, so that the penetrating shaft 24 and the stirring wheel 27 keep rotating synchronously, and the stirring wheel 27 keeps stirring the lubricant flowing continuously, so that the phenomenon of self-precipitation of the lubricant is avoided when the lubricant is located inside the liquid storage barrel 21 or the syringe 22 for a long time;
As can be seen from fig. 7 and 8 in combination with fig. 4, one end of the doctor blade 210 away from the patch shell 29 tends to be attached to the uppermost end of the outer wall of the driven press roll 14, and one end of the doctor blade 210 away from the patch shell 29 is curved, while one end of the doctor blade 210 close to the patch shell 29 is inclined and linear, so that when the driven press roll 14 is subjected to rolling treatment, if impurities carried on the residual plastic raw material on the outer wall of the doctor blade or dust particles in the working environment air remain on the outer wall of the driven press roll 14, the curved part of the doctor blade 210 will scratch off impurities on the surface of the driven press roll 14 along with the rotation of the driven press roll 14, and the scraped impurities will continue to slide downwards along the inclined part of the doctor blade 210, thereby avoiding the problem that the curved part of the doctor blade 210 is blocked due to long-time impurity treatment;
The traction balancing mechanism 3 for maintaining parallelism between the driving press roller 13 and the driven press roller 14 is specifically used as follows:
When the driven press roll 14 is used for a long time or bears heavy pressure, fatigue, thermal expansion or uneven load distribution of the self material can lead to the change of the self shape, such as the local abrasion deformation of the cylinder body, thereby affecting the parallelism between the driving press roll 13 and the driven press roll 14;
As shown in fig. 9 and 10, in the initial state, the driving press roller 13 and the driven press roller 14 are in the same vertical plane and are kept parallel up and down, at this time, the left side and the right side of the driven press roller 14 are kept in a supporting and hanging state with the elastic curved rod 32 through the retaining ring 31, and at this time, the driving press roller 13 and the driven press roller 14 are kept parallel, so that the elastic curved rod 32 is in an isosceles triangle state with a back-off shape as a whole, and under the hanging traction of the elastic curved rod 32, the hinge group 33 at this time is in a regular triangle shrinkage state;
However, when the driven pressing roller 14 is used for a long time, when the outer part of the driven pressing roller 14 is worn and fatigued after bearing heavy pressure, the self quality of the driven pressing roller 14 is uneven due to the wear, the geometric shape of the driven pressing roller 14 is changed, the concentricity of the driven pressing roller is further reduced, so that offset unbalance is caused, at the moment, whether the whole driven pressing roller 14 is offset to the left side or the right side, both ends of the driven pressing roller 14 can lead one side of the driven pressing roller 14 to downwards pull the elastic curved rod 32 through the retaining ring 31 and the other side of the driven pressing roller to upwards squeeze the elastic curved rod 32 through the retaining ring 31, at the moment, the elastic curved rods 32 at both sides of the driven pressing roller 14 can downwards pull and upwards squeeze the hinge group 33 synchronously, as shown in fig. 9, since the hinge group 33 is integrally installed inside the equipment support 11, and the top engagement position of the hinge group 33 is kept in an engaged state with the sliding shaft 34, when the elastic curved bar 32 is pulled downward by the traction force, the hinge group 33 gradually rotates along the inner side wall of the equipment support 11 to make its own contraction angle smaller, and when the elastic curved bar 32 on the other side is pushed upward by the compression force to lift up the hinge group 33, the hinge group 33 gradually rotates along the inner side wall of the equipment support 11 to make its own contraction angle larger, so that the tendency of unbalanced deflection of the driven pressing roller 14 is counteracted by the change traction of the elastic curved bar 32;
As shown in fig. 11 and 12, along with the downward or upward movement of the whole joint position of the hinge group 33, the gear at the joint position of the hinge group 33 drives the sliding shaft 34 to move when rotating, so that the sliding shaft 34 moves synchronously upward or downward, because the sliding shaft 34 and the limiting cylinder 36 are connected in a sliding manner through the cylindrical protrusions and the curved grooves, and the sliding shaft 34 and the limiting cylinder 36 are symmetrically arranged above the equipment bracket 11, when the sliding shaft 34 moves along the inner wall of the limiting cylinder 36, the cylindrical protrusions on the outer wall of the sliding shaft continuously rotate along the inner wall of the curved grooves, so that the sliding shaft 34 moves up and down in a specific movement form under the action of the rotation friction force at the joint position of the hinge group 33, and rotates reversely along with the sliding shaft 34 at the same time, so that the direction marks 35 are driven to rotate reversely, so that the tip positions of the direction marks 35 positioned on two sides of the driven pressing roller 14 correspond to each other, and the direction marks are used as a trend of prompting that the working personnel is in a state that the position of the driven pressing roller 14 is unbalanced at the moment.
