[0019] In this embodiment, a coarse mesh hoisting frame 1 can be installed above the coarse mesh coil loading rack 7, and a slide rail and an electric hoist can be installed on the coarse mesh hoisting frame 1 to facilitate hoisting the coarse mesh material roll or the membrane material roll into place. The coarse mesh coil B4 and the coarse mesh coil A3 can be installed on the top and one side of the coarse mesh coil loading rack 7 respectively, and the membrane coil 2 can be installed on the membrane coil loading and correcting rack 6, and the coil 8 to be loaded can be placed in advance on one side of the membrane coil loading and correcting rack 6.

[0020] A diaphragm CCD detection system can be installed on the coarse mesh coil loading rack 7 according to the position of the diaphragm, and the transported diaphragm can be visually inspected. In order to facilitate the operation of the diaphragm and the coarse mesh, a step 5 can be installed on one side of the coarse mesh coil loading rack 7.

[0021] A diaphragm real-time position detection device A22 and a diaphragm real-time position detection device B23 may be installed at two positions on the upper side of the vacuum conveying device 11, respectively, so as to track the position of the diaphragm in real time.

[0022] In this embodiment, if Figure 5-8 As shown, the structure of the diaphragm center seam adhesive tape device 9 and the coarse mesh to diaphragm device 13 are the same, both include a substrate 91, a linear guide rail 93 is transversely arranged on the upper front side of the substrate 91, a tape gripper moving platform 94 is slidably arranged on the linear guide rail 93, a tape gripper assembly 97 is installed on the lower side of the tape gripper moving platform 94, the tape gripper moving platform 94 is driven by a translation drive assembly 912 to slide back and forth along the linear guide rail 93, a roller 99 is transversely installed on the lower front side of the substrate 91, a tape adsorption strip 98 is axially installed on one side of the roller 99, vacuum adsorption holes are evenly distributed on the tape adsorption strip 98, the roller 99 is driven to rotate by a rotating drive assembly 910 installed on the substrate 91, a tape cutting assembly 92 is installed on the upper side of one end of the roller 99, and a position near the tape cutting assembly 92 on the substrate 91 is installed There is a tape reel 95, and a tape guiding assembly is arranged on a base plate 91 between the tape reel 95 and the tape cutting assembly 92. The tape guiding assembly guides the tape on the tape reel 95 to the position of the tape cutting assembly 92, and the tape is grasped by the tape gripper assembly 97 and pulled flat to the other end of the roller 99. The tape cut by the tape cutting assembly 92 is adsorbed on the tape adsorption strip 8, and the tape is attached to the diaphragm or coarse net being conveyed as the roller 99 rotates. The tape cutting assembly 92 includes a cutter rotating power cylinder 913 and a tape cutter 914 installed on one side of the cutter rotating power cylinder 913. The tape cutter 914 cuts the tape when it rotates toward the direction of the roller 99. The rotation of the roller 99 matches the moving rhythm of the tape gripper mobile platform 94, so that the tape can be continuously attached to the center position of the diaphragm being conveyed, and the production line does not need to stop, which greatly improves the production rhythm.

[0023] Specifically, the substrate 91 is a vertical plate structure and can be installed on a production line. The diaphragm and the coarse mesh both pass through the bottom of the drum 99, so the rotation of the drum 99 matches the transmission speed of the diaphragm and the coarse mesh. When the drum 99 drives the tape adsorption strip 98 to rotate to the bottom, it just corresponds to the center line position of the diaphragm, and the tape can be attached.

[0024] A side plate can be installed at one end of the base plate 91, and the translation drive assembly 912 and the rotation drive assembly 910 can both be installed on the side plate. At the same time, one end of the roller 99 can also be fixed by the side plate, and the other end of the roller 99 is fixed by a fixed bracket 96 installed on the base plate 91. A pad can be installed on the upper end of the fixed bracket 96, and a guide groove matching the width of the tape is provided on the upper end of the pad. After passing through the tape guide assembly, the tape passes horizontally from the guide groove. At the same time, a tape fixing pressing cylinder 911 is installed on the side of the tape cutting assembly 92 close to the tape reel 95 to press the end of the tape cut by the tape cutting assembly 92. In this way, the tape gripper assembly 97 can accurately grasp the end of the tape each time to ensure the continuous operation of the production line. The tape fixing pressing cylinder 911 can be installed on the upper side of the pad, and a pressing block is installed on the protruding rod of the tape fixing pressing cylinder 911. Pressing the end of the tape on the pad can keep the tape from moving.

[0025] like Figure 5 and 8 As shown, the end of the roller 99 is connected to a vacuum rotary air joint 922, and the vacuum adsorption holes on the tape adsorption strip 98 are connected to the vacuum rotary air joint 922. The vacuum rotary air joint 922 is externally connected to a vacuum pump, which can continuously evacuate the vacuum adsorption holes on the tape adsorption strip 98 to form a negative pressure, so that the tape is adsorbed on the tape adsorption strip 98 without falling off until the tape is attached to the diaphragm. The rotation of the roller 99 will not affect the normal use of the vacuum rotary air joint 922. A connecting pipeline can be set inside the roller 99 to connect the vacuum adsorption holes on the tape adsorption strip 98 with the vacuum rotary air joint 922.

[0026] In this embodiment, if Figure 7 The tape gripper assembly 97 includes a tape gripper upper and lower cylinders 971 connected to the tape gripper moving platform 94 and an outer frame 973 installed on the lower end extension rod of the tape gripper upper and lower cylinders 971, a tape clamping wheel 976 is installed at one end of the lower part of the outer frame 973 close to the tape cutting assembly 92, a first gripper cylinder 972 is installed on the outer frame 973, a second gripper cylinder 974 is installed on the lower end extension rod of the first gripper cylinder 972, and a tape gripper piece 975 is installed on the horizontal extension rod of the second gripper cylinder 974 facing the tape clamping wheel 976. The design is ingenious. Through the alternating use of the tape gripper upper and lower cylinders 971, the first gripper cylinder 972 and the second gripper cylinder 974, the tape gripper piece 975 and the tape clamping wheel 976 can clamp, pull, put down and release the end of the tape.

[0027] In this embodiment, if Figure 8As shown, the tape guide assembly includes a plurality of tape guide wheels 915 installed between one end of the roller 99 and the tape reel 95, so that the tape enters between the tape cutting assembly 92 and the roller 99 at a horizontal angle. The tape guide wheels 915 can be flexibly set and the tension can also be adjusted. Specifically, the tape reel 95 can be installed on the upper part of one end of the substrate 91. The tape coming out of the tape reel 95 can be first conducted downward, then conducted upward, and then enter between the tape cutting assembly 2 and the roller 99 in a horizontal state. The tape guide wheels 915 can be installed at the position where the tape needs to be turned, and the number can be adjusted as needed.

[0028] In this embodiment, the tape guiding assembly also includes a tape pre-folding assembly, which includes a swinging member 917 rotatably mounted on the base plate 91, a folding pressure wheel 918 is mounted at the lower end of the swinging member 917, a folding roller 919 having a surface with V-shaped grooves around the circumference is mounted on one side of the folding pressure wheel 918, an elastic member 916 is mounted between the upper end of the swinging member 917 and the base plate 91, the elastic member 916 causes the folding pressure wheel 918 to press against the folding roller 919, forming a folding indentation on the surface of the tape that passes by the folding roller 919, the coordinated use of the folding pressure wheel 918 and the folding roller 919 forms a folding indentation on the surface of the tape, which facilitates the folding of the membrane in the subsequent process, thereby solving the problem that the tape is not easy to fold in the subsequent folding process.

[0029] In this embodiment, a tape presence or absence detection sensor 921 is also installed at the position of the tape guide assembly. Once it is found that the tape being transmitted by the tape guide assembly is broken or used up, the production line can be stopped immediately.

[0030] As a specific implementation of the translation drive assembly 912, Figure 5 and 6 As shown, the translation drive assembly 912 includes a screw rod 9127 parallel to the linear guide rail 93 and a screw rod slider 9126 installed on the screw rod 9127, the screw rod slider 9126 is connected to the tape gripper moving platform 94, one end of the screw rod 9127 is connected to a first driven wheel 9124, one side of the first driven wheel 9124 is provided with a first driving wheel 9122, the first driven wheel 9124 and the first driving wheel 9122 are connected to each other through a first transmission belt 9123, the first driving wheel 9122 is driven by a first power motor 9121, one side of the first driven wheel 9124 and the first driving wheel 9122 is also provided with a first tensioning wheel 9125 in contact with the first transmission belt 9123, and the screw rod transmission enables the tape gripper moving platform 94 to move back and forth accurately.

[0031] As a specific implementation of the rotation drive assembly 910, Figure 5 and 6 As shown, the rotating drive assembly 910 includes a second driven wheel 9103 installed at one end of the rotating shaft of the drum 99 and a second driving wheel 9104 installed on one side of the second driven wheel 9103. The second driven wheel 9103 and the second driving wheel 9104 are connected to each other through a second transmission belt 9105. The second driving wheel 9104 is driven by a second power motor 9101. A second tensioning wheel 9102 in contact with the second transmission belt 9105 is also installed on one side of the second driven wheel 9103 and the second driving wheel 9104.

[0032] As the overall workflow of the diaphragm sticking center seam tape device 9 and the coarse mesh sticking device 13 in this embodiment: Preparation work: first manually install the tape reel 95 onto the chuck, manually pull the tape out from the tape reel 95, bypass the tape guide assembly and the tape pre-folding assembly, and finally fix the tape head to the position of the tape fixing pressing cylinder 911, manually press down the tape cutter 914 to remove the excess end of the tape, and then start the equipment.

[0033] Equipment workflow: The device adjusts the preset parameters, starts the translation drive assembly 912 and the rotation drive assembly 910, and the rotation drive assembly 910 rotates the tape adsorption strip 98 to a vertical upward position. At the same time, the translation drive assembly 912 clamps the tape head with the tape gripper assembly 97, and the upper and lower cylinders 971 of the tape gripper retract. The translation drive assembly 912 moves the tape gripper assembly 97 to the tape placement position and releases the tape head. The vacuum rotary air joint 922 is connected to the vacuum, and the cutter rotary power cylinder 913 is started to drive the tape cutter 914 to cut the tape. At the same time, the tape adsorption strip 98 adsorbs the cut tape. At this time, the diaphragm passes from below, and the device records the position of the diaphragm. After reaching the preset point, the rotation drive assembly 910 rotates the tape adsorption strip 98 synchronously, and the tape is posted to the center of the diaphragm, and it runs in a reciprocating cycle. Similarly, the principle of pasting the coarse mesh to the diaphragm device 13 is the same as that of the diaphragm pasting the center seam tape device 9, the difference is that the coarse mesh to the diaphragm device 13 is pasted with tape to paste the coarse mesh and the diaphragm together.

[0034] In this embodiment, if Figure 3-4As shown, the coarse mesh film slitting device 12 includes a frame 125, a coarse mesh pulling power shaft 1213 is horizontally installed inside the frame 125, a coarse mesh pressing roller 1214 is installed on the upper side of the coarse mesh pulling power shaft 1213, a coarse mesh cutting frame 1210 is installed on one side of the coarse mesh cutting frame 1210, at least one coarse mesh upper cutter 1220 is installed on the coarse mesh cutting frame 1210, a coarse mesh lower cutter 1221 is installed at a corresponding position on the side of the coarse mesh upper cutter 1220, a coarse mesh power transmission component 128 extending to the lower part of the frame 125 is provided on one side of the coarse mesh cutting frame 1210, a film cutting frame 1217 and a corresponding film lower cutter 1219 are installed at the lower part of the frame 125, at least one film is installed on the film cutting frame 1217 The upper cutter 1218, the coarse mesh drawing power shaft 1213, the coarse mesh cutting frame 1210 and the membrane cutting frame 1217 are respectively driven to rotate by the coarse mesh drawing power servo motor 124, the coarse mesh rolling cutting power servo motor 123 and the membrane rolling cutting power servo motor 122 at one end of the frame 125. The coarse mesh can be continuously pulled in through the coarse mesh cutting frame 1210 and the coarse mesh lower cutter 1221 by the rolling of the coarse mesh drawing power shaft 1213 and the coarse mesh pressing roller 1214. During the continuous transportation of the coarse mesh, the coarse mesh can be cut by the coarse mesh upper cutter 1220 and the coarse mesh lower cutter 1221. At the same time, the membrane upper cutter 1218 and the membrane lower cutter 1219 can cut the horizontally transported membrane. The cut coarse mesh segment and membrane segment can be matched and positioned. The whole process does not require the production line to be stopped, thereby ensuring production efficiency.

[0035] In this embodiment, the membrane can pass horizontally between the upper membrane cutter 1218 and the lower membrane cutter 1219 , and the cut membrane segments can also be further transported forward by the vacuum transport device 11 .

[0036] Among them, the coarse mesh upper cutter 1220 is tangentially connected to the coarse mesh cutter frame 1210, and two coarse mesh cutters 1220 can be symmetrically arranged on the outside of the coarse mesh cutter frame 1210. Similarly, the diaphragm upper cutter 1218 is also tangentially connected to the diaphragm cutter frame 1217. The coarse mesh lower cutter 1221 and the diaphragm lower cutter 1219 are both obliquely arranged. When the coarse mesh cutter 1220 moves to a position corresponding to the coarse mesh lower cutter 1221, the coarse mesh cutter 1220 and the coarse mesh lower cutter 1221 form a V-shaped angle. When the diaphragm upper cutter 1218 moves to a position corresponding to the diaphragm lower cutter 1219, the diaphragm upper cutter 1218 and the diaphragm lower cutter 1219 form a V-shaped angle. Such an angle can ensure that the coarse mesh and the diaphragm can be cut off quickly.

[0037] In this embodiment, the frame 125 includes wall panels on both sides and multiple fixing rods connecting the wall panels, forming the frame 125 into a completely hollow structure in the conveying direction, which is convenient for the installation of various internal axial components, and power components such as motors are installed on one of the wall panels.

[0038] like Figure 3 and 4 As shown, the coarse mesh power transmission component 128 is arranged obliquely, and the coarse mesh power transmission component 128 includes a coarse mesh conveyor belt driving shaft 1212 and a coarse mesh conveyor belt driven shaft 1211, and a conveyor belt 1216 is installed side by side between the coarse mesh conveyor belt driving shaft 1212 and the coarse mesh conveyor belt driven shaft 1211, and the coarse mesh conveyor belt driving shaft 1212 is driven to rotate by a coarse mesh conveyor belt power servo motor 121 at one end of the frame 125, and the coarse mesh conveyor belt driving shaft 1212 can be precisely rotated to drive the conveyor belt 1216 to move at a uniform speed to convey the cut coarse mesh segment forward, and the coarse mesh conveyor belt driving shaft 1212 can be arranged at the upper end or at the lower end. Among them, a guide rod 1223 extending obliquely downward is arranged between adjacent conveyor belts 1216. The guide rod 1223 can guide the cut coarse mesh segments and is not prone to deviation. A horizontal part is arranged at the end of the guide rod 1223, which can place the coarse mesh segments stably on the membrane.

[0039] The two ends of the coarse mesh pressing drum 1214 are connected to the lifting cylinder 129 on the frame 125, which can control the height of the coarse mesh pressing drum 1214, thereby automatically adjusting the pressure of the coarse mesh pressing drum 1214 and the coarse mesh pulling power shaft 1213 on the coarse mesh. During transportation, the lifting cylinder 129 drives the coarse mesh pressing drum 1214 to press down. When it is necessary to stop the machine for maintenance, the coarse mesh pressing drum 1214 can be lifted up. The conveying line speed of the coarse mesh power conveying assembly 128 is greater than the conveying line speed of the coarse mesh pulling power shaft 1213, so that the coarse mesh segments cut off form a speed difference with the uncut coarse mesh, and the coarse mesh segments cut off can be separated. The coarse mesh transition shaft 1215 is installed on the other side of the coarse mesh pulling power shaft 1213, and the coarse mesh bypassing the coarse mesh transition shaft 1215 can increase the conveying tension.

[0040] Preferably, a coarse mesh buffer storage assembly 10 is installed on the side of the frame 125 away from the coarse mesh power transmission assembly 128, and the coarse mesh buffer storage assembly 10 includes a first coarse mesh cache roller 106 and a second coarse mesh cache roller 107 arranged side by side at the upper end of the frame 125, and a third coarse mesh cache roller 1022 installed at the lower part of the frame 125. The coarse mesh bypasses the first coarse mesh cache roller 106, the third coarse mesh cache roller 1022 and the second coarse mesh cache roller 107 in sequence. In this way, once there is a problem with the subsequent coarse mesh, the coarse mesh wound on the coarse mesh buffer assembly 10 can be used up first, and there will be no immediate shortage of coarse mesh for cutting, giving the control personnel time to handle it.

[0041] As the specific implementation principle of the coarse mesh film cutting device 12 in this embodiment: Start the equipment, the coarse mesh pulling power servo motor 124 drives the coarse mesh pulling power shaft 1213 to rotate, and the coarse mesh 1224 is stretched forward to a preset length, and the coarse mesh rolling cutting power servo motor 123 is started, driving the coarse mesh cutting knife frame 1210 and the coarse mesh upper cutter 1220 to rotate, and the coarse mesh is cut tangent to the blade of the coarse mesh lower cutter 1221 to cut the coarse mesh, and the cut coarse mesh segment falls into the coarse mesh power conveying component 128, and the coarse mesh conveying belt power servo motor 1 starts quickly, driving the coarse mesh conveying belt driving shaft 1212 to rotate, and the conveying belt 1216 is previously conveyed together with the above coarse mesh segment, and the linear speed of the coarse mesh conveying belt driving shaft 1212 is greater than the linear speed of the coarse mesh pulling power shaft 1213, so that the cut coarse mesh and the uncut coarse mesh form a speed difference, and the cut coarse mesh is separated.

[0042] At the same time, the main line absorbs the film and moves forward to the preset length. The film rolling power servo motor 122 starts to drive the film cutting knife frame 1216 and the film upper cutter 1217 to rotate, and the film is tangent to the blade of the film lower cutter 1219 to cut the film. The main line drives the cut film 25 to continue to move forward. At this time, the end of the coarse mesh segment cut from the top just moves to the middle seam of the cut film segment. This process is controlled by the program closed-loop linkage to control the relative position. The subsequent tape device can fix the coarse mesh to the middle seam of the film. The main line continues to move forward and transports the film-net assembly to the next process. Therefore, the device can cut during the movement of the film and coarse mesh, greatly improving the production cycle.

[0043] In this embodiment, if Figure 9-11The diaphragm folding device 14 includes a folding frame 141, the bottom of the folding frame 141 is hollowed out, a revolving shaft 143 is horizontally installed in the middle of the folding frame 141, the revolving shaft 143 is driven to rotate by a revolving power motor 142 at one end of the folding frame 141, and both ends of the revolving shaft 143 are installed with self-rotating shaft brackets 146 arranged radially along the revolving shaft 143, and a self-rotating shaft 144 is connected between the ends of the self-rotating shaft brackets 146, and an inserting die 145 is axially installed on the outer side of the self-rotating shaft 144, a revolving fixed gear 1410 is coaxially arranged at one end of the revolving shaft 143, and a self-rotating shaft 144 is installed at one end of the self-rotating shaft 144 to cooperate with the revolving fixed gear 1410. The self-rotating gear 1413, when the self-rotating shaft bracket 146 and the revolving shaft 143 rotate, the self-rotating shaft 144 rotates, and when the self-rotating shaft 144 moves to the lower end of the folding frame 141, the die inserting knife 145 remains in a downward state. Through the transmission cooperation between the self-rotating gear 1413 and the revolving fixed gear 1410, the self-rotating shaft 144 and the die inserting knife 145 can rotate synchronously when the revolving shaft 143 and the self-rotating shaft bracket 146 rotate, and the die inserting knife 145 can change its direction following the movement of the diaphragm, and the diaphragm is inserted into the joint between the two diaphragm buffer belt lines 15 and the vacuum conveying device 11. The diaphragm buffer belt line 15 and the vacuum conveying device 11 can fold the diaphragm in half, and the diaphragm can be folded in half during the conveying process without stopping the production line.

[0044] Specifically, the function of the die inserting knife 145 is to fold the film in half at the center seam position, and the conveyor belt on the film conveying platform can act on the film from both sides to fold it in half.

[0045] The revolving power motor 142 can adopt a servo motor with precise speed control. The revolving fixed gear 1410 is fixedly installed on the folding frame 141. The diameter of the revolving fixed gear 1410 is larger than the self-rotating rotating gear 1413. Therefore, the self-rotating rotating shaft 144 can rotate many circles when the self-rotating shaft bracket 146 rotates around the revolving rotating shaft 143 once. In this embodiment, the angular velocity ratio between the revolving fixed gear 1410 and the self-rotating rotating shaft 144 can be set to 1:5.

[0046] like Fig.11 As shown, the die inserting knife 145 and the rotating shaft 144 are installed along the tangent direction, so that the die inserting knife 145 has better directionality as the rotating shaft 144 rotates. When the rotating shaft bracket 146 rotates a relatively small angle, the rotating shaft 144 can rotate a relatively large angle, so that the die inserting knife 145 can point to the center seam of the diaphragm every time the rotating shaft 144 rotates an angle.

[0047] In this embodiment, if Fig.10 As shown, the side of the rotation axis bracket 146 is installed with an adjusting gear 1412 that meshes with the revolving fixed gear 1410 and the rotating gear 1413 at the same time. The angular velocity ratio between the rotating gear 1413 and the revolving fixed gear 1410 can be precisely controlled by adjusting the gear 1412. If a different angular velocity ratio is required, a different adjusting gear 1412 can be replaced, and the position and diameter of the adjusting gear 1412 can be adjusted.

[0048] A motor mounting seat 149 is installed at one end of the folding frame 141, and the revolution rotation power motor 142 is installed at the end of the motor mounting seat 149. The main shaft of the motor mounting seat 149 is connected to the revolution rotation shaft 143 through the coupling 1411 inside the motor mounting seat 149, and the motor mounting seat 149 allows the coupling 1411 to have sufficient installation space. As a connection structure between the revolution rotation shaft 143 and the self-rotation shaft bracket 146, the revolution rotation shaft 143 can be connected to one end of the self-rotation shaft bracket 146, and the other end of the self-rotation shaft bracket 146 can be used to connect the self-rotation rotation shaft 144. When the revolution rotation shaft 143 rotates, the self-rotation rotation shaft 144 can rotate around the revolution rotation shaft 143. As another connection structure between the orbital rotation axis 143 and the rotation axis bracket 146, the orbital rotation axis 143 is connected to the middle part of the rotation axis bracket 146, one end of the rotation axis bracket 146 is connected through the rotation axis 144, and the other end is connected through the supporting connecting column 1415, so that the rotation of the rotation axis bracket 146 and the rotation axis 144 is smoother.

[0049] As a specific connection method of the folding frame 141, Fig. 9 As shown, the folding frame 141 includes side panels 1416 arranged at both ends and multiple connecting rods 1417 for connecting the two side panels 1416. It has a simple structure and is easy to install on the production line, so that the diaphragm can pass horizontally from its bottom. The revolving fixed gear 1410 is fixed on one of the side panels 1416.

[0050] One end of the revolving shaft 143 is provided with a sensing plate 148 extending radially to one side, and the folding frame 141 is provided with a position sensing switch 147 corresponding to the sensing plate 148. The sensing plate 148 rotates together with the revolving shaft 143, and each time it passes through the position sensing switch 147, it can be counted once, so that the number of revolutions of the revolving shaft 143 can be counted, and the number of folding times can also be counted.

[0051] At least one negative ion generator 1418 may also be installed at the bottom of the folding frame 141 to purify the air within the device and improve the quality of the membrane.

[0052] In this embodiment, if Figure 12-14 As shown, the diaphragm fold hot pressing and flattening device 25 includes a mechanism mounting plate 251, which is used to be mounted on the side slide rail of the diaphragm climbing belt line 26 and is driven to move by a translation driving component. At least one lifting power cylinder 254 is installed on the mechanism mounting plate 251, and side mounting support plates 255 are installed on the lower sides of both ends of the mechanism mounting plate 251. A lower hot plate fixing frame 2511 is installed between the lower ends of the side mounting support plates 255, and a lower hot plate 259 is installed on the upper side of the lower hot plate fixing frame 2511. A cylinder 254 is provided between the side mounting support plates 255 to connect with the extension rod of the lifting power cylinder 254. An upper hot plate fixing frame 2515 is connected, and an upper hot plate 258 is installed at the lower end of the upper hot plate fixing frame 2515. The upper hot plate 258 switches between the upper end position and the lower end position under the drive of the lifting power cylinder 254. When the upper hot plate 258 is in the lower end position, it clamps and presses the film bag together with the lower hot plate 259. After the upper hot plate 258 and the lower hot plate 259 fold the film in half and clamp the crease, the entire mechanism mounting plate 251 can be driven by the translation driving component to move along with the transmission of the film. After leveling, the upper hot plate 258 and the lower hot plate 259 can release the film. There is no need to stop the transmission of the film during the whole process.

[0053] Specifically, the diaphragm crease hot pressing and flattening device 25 is in the shape of a long strip as a whole, with a relatively simple structure and a relatively light weight of only 12KG, so it can be easily installed on the side slide rail of the production line and can slide along the side slide rail. The temperature of the upper hot plate 258 and the lower hot plate 259 can be controlled at about 90°C when hot pressing and flattening the diaphragm creases. There are two lifting power cylinders 254, which are respectively installed at the two ends of the mechanism mounting plate 251. The synchronous movement of the two lifting power cylinders 254 can realize the stable lifting and lowering of the upper hot plate fixing frame 2515.

[0054] like Fig.14 As shown, when the entire diaphragm crease hot pressing and flattening device 25 is in use, when the front main line transports the diaphragm to the center of the upper hot plate 258 and the lower hot plate 259, the upper and lower power cylinders 254 extend to press the upper hot plate 258 down to the lower hot plate for 3 seconds. During this process, the entire device will move synchronously along the diaphragm movement trajectory. After 3 seconds, the upper and lower power cylinders 254 retract and release the diaphragm. The diaphragm crease is hot pressed and flattened. The entire device continues to accelerate and move forward for a distance of 10CM, detaches from the diaphragm, and the diaphragm falls back to the main line and continues to be transported forward. The device returns to the initial position and waits for the next cycle. Therefore, the diaphragm does not need to stop during the entire process, and there is no need to change the transmission speed.

[0055] A front mounting support plate 256 is installed on one side of the mechanism mounting plate 251, and a heating plate 2517 is installed at the lower end of the front mounting support plate 256. When the upper heating plate 258 is in the upper end position, it contacts the heating plate 2517, and the upper heating plate 258 can be heated by the heating plate 2517. In this way, there is no need to set a heating component on the upper heating plate 258, making the up and down lifting setting of the upper heating plate 258 more flexible. In other words, there is no need to set a heating component on the upper heating plate 258, and there is no need to consider the installation problem of the heating component dynamically lifting up and down with the upper heating plate 258.

[0056] like Fig.14 As shown, a first heat insulation plate 2514 is arranged between the upper heating plate 258 and the upper heating plate fixing frame 2515, a second heat insulation plate 2510 is arranged between the lower heating plate 259 and the lower heating plate fixing frame 2511, and a third heat insulation plate 257 is installed between the front mounting support plate 256 and the heating plate 2517. By arranging multiple heat insulation plates, the heat on the upper heating plate 258, the lower heating plate 259 and the heating plate 2517 will not be transferred to the entire production line, which not only makes the temperature of the upper heating plate 258 and the lower heating plate 259 more precise, but also makes it safer to use.

[0057] In order to facilitate the heating control of the heating plate 2517 and the lower hot plate 259, an upper heating rod 2512 is installed on the heating plate 2517, and a lower heating rod 2513 is installed on the lower hot plate 259. By installing the upper heating rod 2512 and the lower heating rod 2513 and connecting an external temperature controller, the temperature of the heating plate 2517 and the lower hot plate 259 can be accurately controlled.

[0058] At least two linear bearings 252 are installed on the mechanism mounting plate 251, and an up and down moving shaft 253 is vertically passed through the linear bearing 252. The lower end of the up and down moving shaft 253 is connected to the upper hot plate fixing frame 2515. The cooperation between the up and down moving shaft 253 and the linear bearing 252 can make the up and down movement of the upper hot plate fixing frame 2515 more stable without deflection.

[0059] In this embodiment, if Figure 3-4 As shown, a guide slope 2516 is provided on the lower end surface of the upper heating plate 258 and the upper end surface of the lower heating plate 259 at one end facing the moving direction of the diaphragm, which is conducive to the transmission of the diaphragm from between the upper heating plate 258 and the lower heating plate 259.

[0060] In this embodiment, if Figure 15-16As shown, the vacuum conveying device 11 comprises a negative pressure cavity 119, and side support plates 113 are installed on both sides of the negative pressure cavity 119, and a driving shaft 1113 and a driven shaft 1112 are installed between the side support plates 113 at both ends of the negative pressure cavity 119, respectively, and a driving assembly is installed at one end of the driving shaft 1113, and a porous vacuum conveying belt 111 passing horizontally from the upper side of the negative pressure cavity 119 is wound between the driving shaft 1113 and the driven shaft 1112. An air inlet structure matching the porous vacuum conveyor belt 111 is arranged on the upper side of the negative pressure cavity 119. A negative pressure fan interface 118 is also provided on the negative pressure cavity 119. By providing the negative pressure cavity 119, a continuous negative pressure can be generated when the porous vacuum conveyor belt 111 passes through the upper side of the negative pressure cavity 119, so that the diaphragm on the upper side of the porous vacuum conveyor belt 111 is sucked and conveyed as the porous vacuum conveyor belt 111 moves, so that the transportation of the diaphragm in the entire production line will not stop, thereby improving the production rhythm.

[0061] The negative pressure cavity 119 is set as a flat cavity, and the air inlet structure at the upper end can be set as a mesh structure, which can cover the entire porous vacuum conveyor belt 111. The porous vacuum conveyor belt 111 is evenly distributed with holes. After the negative pressure cavity 119 is connected to the fan through the negative pressure fan interface 118, the air on the upper side of the air inlet structure can be continuously sucked into the negative pressure cavity 119, and negative pressure suction is generated through the evenly distributed holes on the porous vacuum conveyor belt 111, so that the diaphragm is firmly adsorbed on the porous vacuum conveyor belt 111. The active shaft 1113 can realize the cyclic movement of the porous vacuum conveyor belt 111 under the drive of the driving component.

[0062] Among them, multiple cavity reinforcements 1110 are installed on the side walls of the negative pressure cavity 119, so that the overall strength of the negative pressure cavity 119 meets the needs of production line installation and diaphragm transportation. The cavity reinforcement 1110 can adopt a plate-like structure to reinforce the side walls of the negative pressure cavity 119.

[0063] A guide shaft 1114 is installed between the lower parts of the side support plates 113, and the porous vacuum conveyor belt 111 bypasses the outer side of the guide shaft 1114, so that the cyclic movement of the porous vacuum conveyor belt 111 has sufficient tension to meet the needs of efficient film transportation. At the same time, a horizontal tension adjustment plate 112 with a horizontally adjustable position is installed at one end of the side support plate 113, and the driven shaft 1112 is installed between the two horizontal tension adjustment plates 112. A vertical tension adjustment plate 117 with a vertically adjustable position is installed at the lower end of the side support plate 113, and the guide shaft 1114 is installed between the two vertical tension adjustment plates 117. By adjusting the positions of the horizontal tension adjustment plate 112 and the vertical tension adjustment plate 117, the tension of the porous vacuum conveyor belt 111 during the cyclic movement can be adjusted. The positions of the horizontal tension adjustment plate 112 and the vertical tension adjustment plate 117 can be adjusted by the cooperation of screws and slide grooves.

[0064] In this embodiment, at least one anti-deviation rib 1111 is arranged on the inner side surface of the porous vacuum conveyor belt 111, and the anti-deviation rib 1111 is embedded in the corresponding limiting grooves on the active rotating shaft 1113, the driven rotating shaft 1112 and the guide rotating shaft 1114, which can effectively prevent the porous vacuum conveyor belt 111 from deviating during the transmission process. The anti-deviation rib 1111 is arranged along the length direction of the porous vacuum conveyor belt 111.

[0065] like Fig.15 As shown, the driving assembly includes a transmission wheel 116 installed at one end of the active rotating shaft 1113 and a motor 114 installed on the side support plate 113. A transmission belt is connected between the main shaft of the motor 114 and the transmission wheel 116. At the same time, the motor 114 is installed on the side support plate 113 through a motor mounting seat 115. A reduction gearbox can be installed on the output end of the motor 114, and the reduction gearbox is installed on the motor mounting seat 115. A transmission wheel is also installed on the output shaft of the reduction gearbox, which is connected to the transmission wheel 116 on the active rotating shaft 1113 through a transmission belt to realize belt drive.

[0066] The side branch plate 113 is provided with a first mounting plate 1115 extending to one side at one end close to the active rotating shaft 1113, and a connecting plate 1117 is installed on the side of the first mounting plate 1115.

[0067] In this embodiment, if Figure 17-18 As shown, the diaphragm side-pull clamp 24 includes a lifting drive unit 242 installed on the diaphragm side-pull transverse movement device 17 for movement, and a liftable side-pull plate 241 is installed on the lifting drive unit 242. Support folds 243 are provided at both ends of the lower side of the side-pull plate 241, and a cylinder chuck 244 is installed above the support fold 243. The cylinder chuck 244 and the support fold 243 cooperate to pull the membrane bag onto the diaphragm guide cloth docking platform 19, and the cylinder chuck 244 and the support fold 243 clamp the membrane bag, and then the diaphragm side-pull transverse movement device 17 will drive the diaphragm side-pull clamp 24 to move back and forth, and repeatedly stack the membrane bag on the diaphragm guide cloth docking platform 19.

[0068] In this embodiment, if Fig.17 As shown, a diaphragm lifting pressure plate device 20 is installed between the diaphragm positioning platform 16 and the diaphragm guide cloth docking platform 19. The diaphragm lifting pressure plate device 20 includes a transverse rotating shaft 201 installed transversely above the diaphragm positioning platform 16. A plurality of downward extending pressure plates 203 are installed axially on the transverse rotating shaft 201. A pressure plate rotation drive motor 202 is provided at one end of the transverse rotating shaft 201 to ensure that the membrane bag will not lift up when moving.

[0069] As the operation mode of the entire production line: Preliminary preparations for equipment operation: 1: Manually use the coarse mesh hoisting rack 1 to hang the coarse mesh roll and the membrane roll and transport them to the designated location, such as the membrane roll 2, coarse mesh roll A3, and coarse mesh roll B4 in the figure, and fix the rolls.

[0070] 2: Coarse mesh coil A3 and coarse mesh coil B4 are used one by one and kept as a backup, and are used alternately in actual production process.

[0071] 3: Manually pull the membrane along the membrane path and adsorb it onto the vacuum conveying device 11. Note that the membrane length must exceed the coarse mesh membrane slitting device 12. The vacuum conveying device 11 starts negative pressure to adsorb the membrane onto the wire.

[0072] 4: Manually press the manual button for film cutting, and the coarse mesh film cutting device 12 rotates one circle to cut off the film ends that exceed the end, and manually take out the cut waste film ends from the equipment and put them into the designated waste disposal area.

[0073] 5: Manually pull out the coarse mesh along the mesh path, note that the length of the coarse mesh must exceed the coarse mesh diaphragm slitting device 12, and clamp the coarse mesh on the coarse mesh diaphragm slitting device 12.

[0074] 6: Manually press the coarse mesh cutting manual button to cut off the coarse mesh that exceeds the end, and manually take the cut waste coarse mesh end material out of the equipment and put it into the designated waste disposal area.

[0075] Automatic workflow: 1: Manually input the new film material number parameters in the industrial computer and start the equipment.

[0076] 2: The vacuum conveying device 11 absorbs the film and moves forward. The film coil feeding and correcting frame 6 starts the correcting function to prevent the film from running out of the belt line during movement. The film center seam tape device 9 sticks the tape to the film at the appropriate position (the center of the single film). When the film runs to the set parameter position, the coarse mesh film slitting device 12 runs synchronously to cut a section of the film to form a single film. The single film is still absorbed on the vacuum conveying device 11 and continues to move forward.

[0077] 3: At the same time, the coarse mesh film slitting device 12 is started, the coarse mesh is pulled to the parameter-set length, and the coarse mesh is cut to form a single piece of coarse mesh.

[0078] 4: When the center seam of the single membrane moves to the end of the single coarse mesh, the coarse mesh is attached to the membrane device 13 and rotated to fix the coarse mesh to the center seam of the single membrane to form a membrane-mesh composite sheet.

[0079] 5: The membrane-net composite sheet is still adsorbed on the vacuum conveying device 11 and continues to move forward.

[0080] 6: When the center seam of the membrane-net combination sheet moves to the bottom of the membrane folding device 14, the membrane folding device 14 rotates to extrude the center seam of the membrane-net combination sheet downward to form a fold. The folded membrane wraps the coarse mesh to form a membrane bag. At this time, the membrane is U-shaped with the coarse mesh in the middle of the membrane.

[0081] 7: The film bag continues to move downward from directly below the film folding device 14 and reaches the film folding hot pressing and flattening device 25. The film folding hot pressing and flattening device 25 starts, clamps the end of the film bag, and moves forward synchronously.

[0082] 8: The membrane folding device 14 moves for a few seconds. After 3 seconds, the clamping is released, the membrane is released, the membrane fold is hot-pressed and flattened, and the membrane folding device 14 continues to accelerate and move forward for a distance of 10CM, detaching from the membrane, and the membrane bag falls back to the membrane climbing belt line 26 to continue to be transported forward, and the membrane folding device 14 returns to the initial position.

[0083] 9: After the film bag is transported to the film positioning platform 16, the film is positioned for the second time, the film is placed on the tilting plate device 20 to flatten the film bag, and the film side pulling claws 24 clamp the film bag. At this time, the film placing tilting plate device 20 is reset, and the film side pulling device 17 moves to transport the film bag to the film and guide cloth docking platform 19.

[0084] 10: The diaphragm side-pull device 17 and the diaphragm side-pull clamping jaws 24 are reset.

[0085] Note that in the above process, 2-10 can operate synchronously, which greatly improves the production rhythm of the entire roll film.
