Detailed description of the preferred embodiments
In order to make the technical solutions of the present invention better understood, those skilled in the art will now describe the present invention in further detail with reference to the accompanying drawings.
As shown in fig. 1 to 5, an intelligent production apparatus for a composite geomembrane 7 according to an embodiment of the present invention includes a frame 1 disposed outside a heater, and a guide assembly 2 disposed on the frame 1 (the guide assembly 2 mainly guides a material heated at a high temperature to a rolling composite assembly 3, and the rolling composite assembly 3 may be formed by a simple long rod rotatably disposed on the frame 1, and the number of the long rod is adaptable according to the amount of the material), and the rolling composite assembly 3 (the rolling composite assembly 3 may be formed by relatively rotating two rollers which are disposed in a group and are vertically symmetrical to each other to roll and composite a multilayer material, or may be formed by a plurality of groups of two rollers which are symmetrically disposed and relatively rotate), where the guide assembly 2 guides two materials heated at a high temperature by the heater (one cloth-one film, one cloth-two films, two cloth-one film, two cloth-two films, and multiple cloth-multiple films, etc. because the product specifications of the composite geomembrane 7 are various, there are one cloth-two films, one film, two cloth-two films, and a plurality of the rollers are disposed correspondingly, and the rolling composite assembly 3 further includes:
rate of tension determine module 4, it is located guide subassembly 2 with on 1 part of support body between the compound subassembly 3 of roll-in, rate of tension determine module 4 includes pressure feedback mechanism (pressure feedback mechanism here can be pressure sensor, and pressure sensor can examine on receiving the material, and pressure sensor detects pressure this for prior art, and this is not repeated here), pressure feedback mechanism carries out the tensile force to two kinds of materials of coming from guide subassembly 2 respectively and detects.
And the tension adjusting component 5 is arranged on the guide component 2 and the part of the frame body 1 between the pressure detection components, and comprises a speed adjusting mechanism which is based on a detection signal of the pressure feedback mechanism and is used for adjusting the stroke speeds of two materials about to enter the rolling composite component 3 respectively.
Specifically, the heated geomembrane 7 and the non-woven fabric 8 come out of the heater and move towards the rolling composite component 3 through the guide component 2, during the process, the geomembrane 7 and the non-woven fabric 8 are in contact with the speed adjusting mechanism and then in contact with the pressure feedback mechanism, the pressure feedback mechanism detects the tensioning condition of the geomembrane 7 and the non-woven fabric 8 between the speed adjusting mechanism and the rolling composite component 3, namely the tensioning degree of the geomembrane 7 or the non-woven fabric 8 is different from that of the pressure feedback mechanism, and the tensioning conditions of the geomembrane 7 and the non-woven fabric 8 are limited when the geomembrane 7 and the non-woven fabric 8 are in rolling composite, for example, the tensioning force applied to the pressure feedback mechanism after the geomembrane 7 is tensioned is within the range of 100-150N, the non-woven fabric 8 is tensioned to the range of 80-150N, therefore, when the force applied to the pressure feedback mechanism by the geomembrane 7 is lower than 100N or higher than 150N, the pressure feedback mechanism detects the change and converts the change into an electric signal to the speed adjusting mechanism, and then the speed adjusting mechanism adjusts the rolling composite speed of the geomembrane 7 and the non-woven fabric 8 to the principle that the geomembrane 7 is too high tensioning degree.
The invention has the beneficial effects that: when geomembrane 7 and non-woven fabrics 8 roll-in are compound, the expansion with heat and contraction with cold deflection of the two need be in the regulation within range, after geomembrane 7 and non-woven fabrics 8 come out from the heater, when coming into the roll-in composite component 3 soon, there is a process that the temperature reduces, so geomembrane 7 and non-woven fabrics 8 have the change of different heat deflection, consequently, carry out the tensile force to geomembrane 7 and non-woven fabrics 8 that are about to get into roll-in composite component 3 through pressure feedback mechanism earlier and detect, can learn the change condition of the heat deflection of the two, rethread speed adjustment mechanism is based on the detected signal of pressure feedback mechanism, adjust the stroke speed of geomembrane 7 and non-woven fabrics 8 that are about to get into roll-in composite component 3 respectively, so that the contraction with cold deflection of the two can the even change, avoid geomembrane 7 and non-woven fabrics 8 roll-in compounding to appear the uneven problem of thin thickness.
Preferably, two first guide rollers 10 are arranged on the frame body 1, the speed adjusting mechanism drives the two first guide rollers 10 to respectively convey two materials (the non-woven fabric 8 and the geomembrane 7), and a release film is sleeved on the surface of each first guide roller 10; specifically, in the embodiment of the present invention, a release film is sleeved on the surface of the first conveying roller 10 (the release film refers to a film whose surface can be distinguished, that is, the release film has slight viscosity after contacting with a corresponding material under a limited condition), which can bring the following beneficial effects:
one of them, because non-woven fabrics 8 and 7 compound surfaces of geomembrane all can be scribbled with glue, take place excessive adhesion problem when the surface that scribbles glue for preventing non-woven fabrics 8 and geomembrane 7 contacts with first conduction roller 10, when scribbling glue and geomembrane 7 on from type membrane and the soil non-woven fabrics 8 when scribbling glue and geomembrane 7 have slight viscidity, can reduce the probability of the problem of skidding appearing when non-woven fabrics 8 and geomembrane 7 pass through first conduction roller 10, if take place the problem of skidding, just can lose the speed governing action to non-woven fabrics 8 and geomembrane 7.
Two, when non-woven fabrics 8 and geomembrane 7 conduct through first conduction roller 10, first conduction roller 10 all has certain squeezing action to non-woven fabrics 8 and geomembrane 7, owing to the effect from the type membrane, can be so that glue that 8 surfaces of non-woven fabrics were paintd because the inside partly of effect infiltration of squeezing force, glue increases with the area of contact of non-woven fabrics 8 like this, and glue is better to the bonding effect of non-woven fabrics 8, and 8 firmness of non-woven fabrics also can increase.
Third, when from the slight adhesion of type membrane and glue, the glue that is in 8 surfaces of non-woven fabrics and the glue that is in 7 surfaces of geomembrane can be because the wire drawing phenomenon appears in slight adhesion, so glue on the non-woven fabrics 8 and glue on the geomembrane 7 area of contact increase when the roll-in is compound, and the wire drawing can appear the phenomenon of cross contact, and the effort between so glue is stronger for the further improvement of the bonding effect of non-woven fabrics 8 and geomembrane 7.
Preferably, the speed adjusting mechanism comprises two driving wheels 50, two driven wheels 51 and two linkage pieces for respectively transmitting the power of the two driving wheels 50 to the two driven wheels 51;
a first driving part is arranged on the frame body 1, the two driving wheels 50 are arranged on the first driving part (optional motor), the two driven wheels 51 are respectively connected with the two first transmission rollers 10 in a one-to-one correspondence manner, and the linkage part is arranged on the frame body 1;
the driving wheel 50 comprises an inner concave section with gradually reduced radial dimension, and in an axial sectional view, the inner concave section comprises two main sector surfaces symmetrical by an axial central line thereof, and correspondingly, the driven wheel 51 is also of the same structure, and in the axial sectional view, the driven wheel 51 comprises two auxiliary sector surfaces symmetrical by the axial central line thereof, and the two adjacent main sector surfaces and the auxiliary sector surfaces are positioned on a virtual circle 510;
the linkage member includes a speed-changing wheel 52 arranged at the center of the virtual circle 510 and a second driving member (the second driving member may be a motor) for driving the speed-changing wheel 52 to rotate around the center of the virtual circle 510 based on the detection signal of the pressure feedback mechanism, and the circumferential section circle 520 of the speed-changing wheel 52 is the same as the center of the virtual circle 510 and is perpendicular to the plane (see fig. 4 and 5).
Specifically, when the tension of the geomembrane 7 or the non-woven fabric 8 between the first driving member 10 and the rolling composite component 3 needs to be adjusted, the first driving member drives the driving wheel 50 to rotate at a constant speed when in operation, the driving wheel 50 drives the speed change wheel 52 to rotate, the speed change wheel 52 drives the driven wheel 51 to rotate, the driven wheel 51 drives the first driving member 10 to rotate, the driving wheel 50 and the driven wheel 51 rotate in the same direction, the rotation of the first driving member 10 can drive the geotextile or the non-woven fabric 8 attached to the surface of the first driving member to move towards the rolling composite component 3, when the pressure sensor detects that the tension of the geomembrane 7 or the non-woven fabric 8 is not in the limited range, the signal can be transmitted to the linkage member, the second driving member operation control speed change wheel 52 takes the center of the virtual circle 510 as the rotation center and rotates along the arc direction of the virtual circle 510, because of the structural characteristics of the driving wheel 50 and the driven wheel 51, the radial dimensions of the driving wheel 50 and the driven wheel 51 are changed from small to large, that is, the variable speed wheel 52 rotates along the arc direction of the virtual circle 510, if the feeding speed of the geomembrane 7 or the non-woven fabric 8 needs to be increased, the variable speed wheel 52 rotates towards the direction that the radial dimension of the driven wheel 51 is reduced and rotates towards the direction that the radial dimension of the driving wheel 50 is increased, if the feeding speed of the geomembrane 7 or the non-woven fabric 8 needs to be reduced, the variable speed wheel 52 rotates towards the direction that the radial dimension of the driven wheel 51 is increased and rotates towards the direction that the radial dimension of the driving wheel 50 is reduced, so that the feeding speed of the geomembrane 7 or the non-woven fabric 8 can be adjusted to be within a limited range before the geomembrane 7 and the non-woven fabric 8 are rolled and compounded.
As a further feature of the embodiment of the present invention, when the geomembrane 7 or the nonwoven fabric 8 coming out of the heater expands with heat and contracts with cold, the force required by the first transfer roller 10 to transfer the geomembrane 7 or the nonwoven fabric 8 increases, so that a tensile force is generated to both the heated geomembrane 7 and the heated nonwoven fabric 8, and therefore, in order to avoid a large destructive tensile force to the geomembrane 7 and the nonwoven fabric 8, if the tensile force cannot exceed 100N, the frictional force between the driving wheel 50 and the change wheel 52 is now set within a range smaller than the destructive tensile force, for example, 80N, so that when the tensile force exceeds 80N and does not reach 100N, a slip or even an idle rotation phenomenon occurs between the driving wheel 50 and the change wheel 52, and when the driving wheel 50 idles, the control center receives the signal, the first driving member stops operating, and when the length of the geomembrane 7 or the nonwoven fabric 8 coming out of the heater is normal, the first driving member continues to operate, thereby protecting the geomembrane 7 and the nonwoven fabric 8.
Further, the drive pulley 50 is in frictional contact with the transmission pulley 52 in the circumferential direction, and is in sliding contact in the radial direction; the driven pulley 51 is in frictional contact with the transmission pulley 52 in the circumferential direction and is in sliding contact in the radial direction.
Specifically, when the second driving element drives the variable speed wheel 52 to rotate along the arc of the virtual circle 510, the position of the variable speed wheel 52 needs to be changed in time, so that the feeding speed of the geomembrane 7 or the non-woven fabric 8 can be adjusted at the first time, and due to the time difference caused by the frictional resistance, even if the feeding speed of the geomembrane 7 or the non-woven fabric 8 is adjusted, the geomembrane 7 or the non-woven fabric 8 may be slightly overlapped in thickness and thickness during rolling and compounding, therefore, the friction between the driving wheel 50 and the variable speed wheel 52 and the friction between the driven wheel 51 and the variable speed wheel 52 are circumferential, so that the transmission of the power is not influenced, and the time difference caused by the frictional resistance can be effectively shortened in the radial direction.
Still further, be equipped with two second biography deflector rolls 11 on the support body 1 and with two first biography deflector roll 10 one-to-one installs biography deflector roll 12 on the second biography deflector roll 11, from driving wheel 51 through the friction with power transmission for biography deflector roll 12, first biography deflector roll 10 with the corresponding position second biography deflector roll 11 conducts same material jointly.
Specifically, even though the release film is arranged on the surface of the first conducting roller 10, the release film is slightly adhered to the glue, but the slippage problem still occurs, so that in the embodiment of the invention, the second conducting roller 11 is installed on the frame body 1, so that the conduction of the geomembrane 7 and the non-woven fabric 8 is conducted by the first conducting roller 10 and the second conducting roller 11 at corresponding positions together, the first conducting roller 10 and the second conducting roller 11 have a certain extrusion effect on the conducted geomembrane 7 or the non-woven fabric 8, so that the non-woven fabric 8 or the geomembrane 7 is subjected to two friction forces when passing through the first conducting roller 10, and the slippage problem is reduced again, so that the slippage probability is reduced, and the first conducting roller 10 and the second conducting roller 11 play a role of isolation together, so that the feeding of the geomembrane 7 or the non-woven fabric 8 between the first conducting roller 10 and the rolling composite component 3 is not affected by the length of the geomembrane 7 or the non-woven fabric 8 just coming out of the heater.
Preferably, rate of tension determine module 4 still includes two sets ofly to set up with the material symmetry two sets of spouts 40 on the support body 1, every group spout 40 quantity is two and the symmetry sets up, it is equipped with slider 41 to slide in the spout 40, spout 40 one end with be connected with first spring between the slider 41, install the third on the slider 41 and pass deflector roll 42.
Specifically, the geomembrane 7 and the non-woven fabric 8 contact the third guiding roller 42 before entering the rolling composite assembly 3, so that the tension of the geomembrane 7 and the non-woven fabric 8 is reflected on the displacement distance of the third guiding roller 42, that is, the first spring makes the slider 41 move in the chute 40, so that the third guiding roller 42 can be attached to the surface of the geomembrane 7 or the non-woven fabric 8, and has a certain supporting force for both, so that the geomembrane 7 and the non-woven fabric 8 slightly change in trajectory when contacting the third guiding roller 42 at the corresponding position, so that when the tension of the geomembrane 7 or the non-woven fabric 8 is high, a pressing force is generated on the third guiding roller 42, so that the slider 41 is driven by the third guiding roller 42 to move in the chute 40, the first spring contracts, and when the tension of the geomembrane 7 or the non-woven fabric 8 is low, the third guiding roller 42 is not pressed by both, at this time, the first spring extends, so that the third guiding roller 42 continues to be attached to the surface of the geomembrane 7 and the non-woven fabric 8 at the corresponding position, and the pressure sensor can be arranged on the surface of the non-woven fabric 42 to detect the change of the geomembrane 7 and the third guiding roller 8.
Preferably, the pressure feedback mechanism comprises a pressure sensor, the pressure sensor is used for detecting the change of the elastic force of the first spring, an alarm system is arranged on the frame body 1, and the alarm system generates an alarm signal based on a signal of the pressure sensor; specifically, if the pressure sensor is arranged on the third transmission roller 42, when the tension of the geomembrane 7 or the non-woven fabric 8 is gradually loosened, the interaction force between the third transmission roller 42 and the geomembrane 7 or the non-woven fabric 8 may be constant at the moment, that is, a balanced state is achieved between the third transmission roller and the geomembrane 7 or the non-woven fabric 8, and the change of the interaction force between the third transmission roller 42 and the geomembrane 8 is stopped until the tension of the geomembrane 7 or the non-woven fabric 8 is changed, so that the pressure sensor is arranged on the first spring for detecting the elastic force change of the first spring, and when the tension change of the geomembrane 7 or the non-woven fabric 8 is not within a limited range, the pressure sensor detects that the elastic force change of the first spring is out of range, and transmits a signal to the alarm system to remind a worker of paying attention to the operation of the equipment, so as to find problems in time, and overhaul the equipment, and avoid the influence on the operation of the composite geomembrane 7.
Preferably, the force required for the material to elastically deform through the third conducting roller 42 comes from the elastic force applied to the third conducting roller 42 by the first spring, and the first spring always has a tendency of restoring elongation; specifically, the force applied to the third guide roller 42 by the first spring only slightly supports the geomembrane 7 and the non-woven fabric 8 when acting on the geomembrane 7 and the non-woven fabric 8 at corresponding positions through the third guide roller 42, namely, the elastic deformation with a small amplitude does not influence the feeding speed of the speed adjusting structure for adjusting the geomembrane 7 or the non-woven fabric 8, and because when the interaction force exists, the change of the interaction force after the detection can be better.
Further, the second driving member includes a shaft 53 rotatably disposed on the frame body 1, the gearbox 52 is rotatably mounted on the shaft 53, the slider 41 is provided with a rack 54, one end of the shaft 53 close to the slider 41 is provided with a gear 55, and the rack 54 is engaged with the gear 55.
The pressure feedback mechanism mentioned above can use a pressure sensor to abut against the material to directly detect the tension of the material, which is a relatively precise pressure detection method, but there are many precise instruments used therein, so the embodiment of the present invention further provides a relatively rough pressure detection method and corresponding method compared with the pressure sensor, that is, the third guide roller 42 contacts with the material, the pressure applied by the material to the third guide roller 42 will generate thrust to the material, and the third guide roller 42 drives the sliding block 41 to slide in the sliding groove 40, so that the first spring will be subject to the expansion change, thereby detecting the tension change of the material.
Specifically, when the tension of the geomembrane 7 or the non-woven fabric 8 changes, the force applied to the third guide roller 42 drives the third guide roller to change its position, the third guide roller 42 drives the sliding block 41 to slide in the chute 40, the sliding block 41 drives the rack 54 to move synchronously, the rack 54 drives the gear 55 engaged with the rack to rotate, the gear 55 rotates to drive the shaft 53 to rotate, the shaft 53 rotates to drive the speed-changing wheel 52 to rotate, the speed-changing wheel 52 can cooperate with the driving wheel 50 and the driven wheel 51 to realize the speed regulation of the first guide roller 10, that is, the feeding speed of the geomembrane 7 and the non-woven fabric 8 is regulated, so that the tension of the geomembrane 7 and the non-woven fabric 8 is related to the position of the sliding block 41 in the chute 40, the displacement of the sliding block 41 in the chute 40 is related to the cooperation of the gear 55 through the rack 54 and then is reflected to the speed regulation mechanism, therefore, the tension change of the geomembrane 7 and the non-woven fabric 8 can not be caused by the tension change of the geomembrane 7 and the non-woven fabric 8 due to the signal of the pressure sensor, the tension change signal of the geomembrane 7 and the non-woven fabric 8 can be more directly fed back to the speed adjusting mechanism, the speed adjusting mechanism can adjust the feeding speed as long as the sliding block 41 has displacement change, so that the feeding speed of the geomembrane and the non-woven fabric 8 can be adjusted, when the pressure feedback mechanism uses the pressure sensor to detect the tension of the material, the pressure value acted on the pressure sensor at a certain moment of the material can be detected, then after the feeding speed of the material is adjusted through speed adjustment, the pressure is kept at a certain fixed value, such as 70N, when the first spring is matched with the sliding block, the pressure value acted on the third conducting roller at a certain moment of the material can be detected, the pressure is then maintained within a certain range, for example between 60N and 80N, after adjusting the material feed rate by means of speed adjustment.
Further, a passive speed reduction mechanism 6 is arranged on the rolling composite component 3, and the passive speed reduction mechanism 6 reduces the speed of the rolling composite component 3 based on the power of the slide block 41 (see fig. 4); specifically, no matter the geomembrane 7 is fed into the rolling composite component 3 or the non-woven fabric 8 is fed into the rolling composite component 3, once the tension between the first transmission roller 10 and the rolling composite component 3 is greatly changed, the rolling composite between the geomembrane 7 and the non-woven fabric 8 is certainly influenced, because the tension between the geomembrane 7 and the non-woven fabric 8 is changed, the rolling composite component 3 continues to roll the composite geomembrane 7 and the non-woven fabric 8 at the previous speed, and the increase of the uneven thickness area of the composite geomembrane 7 is increased, therefore, the passive speed reduction mechanism 6 is arranged on the rolling composite component 3, when the tension between the geomembrane 7 and the non-woven fabric 8 is greatly changed, the sliding block 41 is enabled to displace in the sliding groove 40, the sliding block 41 not only can carry out variable speed adjustment on the speed adjustment mechanism, but also can transmit power to the passive speed reduction component, so that the passive speed reduction component applies resistance to the rotation of the rolling composite component 3, the speed reduction can be reduced to a certain extent, as the preferred scheme of the embodiment of the invention is that a plurality of two groups of rollers which are symmetrically arranged and rotate relatively, thus, when the non-woven fabric 7 and the non-woven fabric 8 are changed, the rolling composite component, the rolling composite geomembrane 7 and the rolling composite component can be prevented from entering the rolling composite geomembrane 7 and the composite component from entering the rolling composite geomembrane thickness of the composite geomembrane thickness is increased, and the composite geomembrane thickness is increased, thereby, the composite geomembrane thickness problem of the composite geomembrane is prevented.

A second spring is connected between the last slide 61 from the position close to the speed adjustment mechanism and the end of the slide bar 60 remote from the speed adjustment mechanism.
The slider 41 is provided with a force application block 65, a force application rod 66 is mounted on the first slide carriage 61 from the position close to the speed adjustment mechanism, the frame body 1 is hinged with a first force application rod 67 and a second force application rod 68, when the slider 41 moves in different directions in the slide slot 40, the force application block 65 can be respectively driven to apply thrust to the first force application rod 67 and the second force application rod 68, the first force application rod 67 generates thrust to the second force application rod 68 after being stressed, and the hinge point of the second force application rod 68 and the frame body 1 is close to one end of the second force application rod 68 close to the slide slot 40 (see fig. 4).
Specifically, no matter the tension of the geomembrane 7 and the nonwoven fabric 8 exceeds the limited range or is lower than the limited range, the slide block 41 slides in the chute 40, and no matter which direction the slide block 41 moves in the chute 40, the force application block 65 is not enabled to press the first force application rod 67 but the second force application rod 68, but the first force application rod 67 is pressed, the first force application rod 67 is also enabled to press the second force application rod 68, as a result, the second force application rod 68 is enabled to generate a thrust force on the force application rod 66 close to the force application rod 68, the force application rod 66 drives the slide carriage 61 connected with the force application rod to move together, and the hinge point of the second force application rod 68 and the frame 1 is close to one end of the second force application rod 68 close to the chute 40, in this case, the force application block 65 directly presses the second force application rod 68 or indirectly passes through the first force application rod 67 to press the second force application rod 68, the second force application rod 68 further generates a thrust force on the force application rod 66 close to the force application rod, that the force application rod 68 has an amplification effect, namely, the same swinging distance is increased when the circle center is increased.
When the slide carriage 61 is pushed to slide on the slide rod 60 in a direction away from the speed adjustment mechanism, the top block 62 on the slide carriage 61 generates a pressing force on the friction plate 63 slidably connected therewith, the friction plate 63 is hinged with the next slide carriage 61, and so on, the last slide carriage 61 is connected with the slide rod 60 by the second spring, so that the friction plate 63 moves in a direction with the minimum force, namely, rotates along the hinge point to gradually contact with the friction wheel 64, after the friction plate 63 contacts with the friction wheel 64, the friction wheel 64 gives a reaction friction force to the friction plate 63, so that the friction plate 63 tends to move away from the speed adjustment mechanism and reversely press the first slide carriage 61, and the slide carriage 61 is influenced by the second force applying rod 68, and the second force applying rod 68 is directly or indirectly influenced by the displacement of the slide block 41, and the friction plate 63 is both pushed by the top block 62 and the friction force of the friction wheel 64, so that the friction plate 63 starts to move toward the second spring.
