[0085] In this scheme, if Figure 3 As shown, the mesh pulling mechanism 2 includes: a mesh pulling mechanism 21, a mesh tensioning mechanism 22 and a mesh stretching mechanism;

[0086] The wire mesh pulling mechanism 21 is arranged at the front end of the frame 1, and is used to pull the starting end of the wire mesh in the wire mesh coil;

[0087] The wire mesh tensioning mechanism 22 is arranged at the rear end of the frame 1, and is used to tension the rear part of the wire mesh in the wire mesh coil that is pulled into the frame 1;

[0088] The wire mesh stretching mechanism is arranged between the front end and the rear end of the frame 1, and is used to flatten the left and right sides of the wire mesh in the wire mesh roll that is pulled into the frame 1.

The second wire mesh stretching mechanism may include two second wire mesh stretching components arranged opposite to each other. Each second wire mesh stretching component may include a second wire mesh clamp and a second cylinder. The second cylinder may be arranged on the outside of the bracket of the front pressing part. The second wire mesh clamp is arranged at the free end of the second cylinder and may be located on the inside of the bracket of the front pressing part, and is used to clamp one side of the front part of the wire mesh pulled into the frame 1. In this way, the front and rear sides of the wire mesh pulled into the frame 1 in the wire mesh coil are flattened, and the wire mesh pulled into the frame 1 in the wire mesh coil is also flattened horizontally (along the left and right directions of the frame 1).

[0090] In addition, the starting end of the wire mesh in the wire mesh coil can be manually passed through the wire mesh tensioning mechanism 22, the first wire mesh stretching mechanism 39, the mesh stretching mechanism, the second wire mesh stretching mechanism, and the wire mesh traction mechanism 21 in sequence, and the wire mesh pulled into the frame 1 can be firstly longitudinally flattened by the wire mesh traction mechanism 21 and the wire mesh tensioning mechanism 22, and then the wire mesh pulled into the frame 1 can be transversely flattened by the first wire mesh stretching mechanism 39 and the second wire mesh stretching mechanism, thereby making the wire mesh pulled into the frame 1 longitudinally flattened and transversely flattened, and finally the mesh stretched mechanism 3 can be used to tighten the wire mesh pulled into the frame 1 and in a flattened state; in addition, the wire mesh coil support can be set at the front side of the frame 1. Of course, as mentioned above, when the wire mesh pulled into the frame 1 completes the screen making, the wire mesh in the wire mesh coil can be pulled into the frame 1 again by the wire mesh traction mechanism 21 to wait for the making of the next screen.

[0097] In addition, when the starting end of the wire mesh in the wire mesh roll can be manually passed through the mesh stretching mechanism 3, it actually passes through the rear mesh pressing mechanism 32 first, and then passes through the left mesh pressing mechanism 33 and the right mesh pressing mechanism 34 at the same time, and then passes through the front mesh pressing mechanism 31; in addition, after the mesh stretching mechanism 2 flattens the wire mesh, the front mesh pressing mechanism 31 and the rear mesh pressing mechanism 32 are first triggered simultaneously to achieve longitudinal compression of the wire mesh, and the left mesh pressing mechanism 33 and the right mesh pressing mechanism 34 are then triggered simultaneously to achieve lateral compression of the wire mesh.

In addition, the telescopic sequence of the first telescopic mechanism 35, the second telescopic mechanism 36, the third telescopic mechanism 37 and the fourth telescopic mechanism 38 is: the first telescopic mechanism 35 and the second telescopic mechanism 36 can be extended at the same time first, and the third telescopic mechanism 37 and the fourth telescopic mechanism 38 can be extended at the same time later.

[0104] Of course, when the mesh stretching mechanism 3 completes the longitudinal and transverse tensioning of the wire mesh, the wire mesh traction mechanism 21, the wire mesh tensioning mechanism 22 and the wire mesh stretching mechanism of the mesh pulling mechanism 2 can stop working, that is, in this case, the mesh pulling mechanism 2 can stop working, and the lifting platform needs to lift the screen frame 6 so that the screen frame 6 rises to a certain height and then abuts against the wire mesh. At this time, the four telescopic mechanisms of the mesh stretching mechanism 3 can be retracted and maintained after reaching the set value, which makes the wire mesh mainly affected by the lifting force of the screen frame 6 in this scenario, so that the operating mechanism 5 can perform related operations on the wire mesh and the screen frame 6 after abutment.

[0105] Among them, Figure 7 and Figure 8As shown, the first telescopic mechanism 35 can adopt two first front and rear telescopic components, and the two first front and rear telescopic components can be arranged in parallel at the front part of the frame 1 through the first support, and the telescopic ends thereof can be connected to the bottom of the front pressing mechanism 31 through the first connecting seat; of course, the longitudinal movement of the front pressing mechanism 31 can be realized through the first telescopic mechanism 35;

Of course, the telescopic sleeve is equivalent to the nut sleeve of the lead screw assembly, and a rotation-stopping structure for matching with the first end and the middle part of the telescopic sleeve is provided in the sleeve to prevent the telescopic sleeve from rotating with the lead screw, and a lubricating sleeve can also be provided between the inner circumferential wall of the second part of the sleeve and the outer circumferential wall of the middle part of the telescopic sleeve. Similarly, a lubricating sleeve can also be provided between the inner circumferential wall of the first part of the sleeve and the outer circumferential wall of the first end of the telescopic sleeve;

[0112] A sprocket drive assembly can be arranged on the frame 1, and is used to drive the driven sprocket on the second end of the lead screw to rotate. The sprocket drive assembly can be composed of a servo motor, a driving sprocket and a transmission belt, etc. A driving sprocket is sleeved on the output shaft of the servo motor, and is transmitted and matched with the driven sprocket on the second end of the lead screw through the transmission belt; that is, the lead screw assembly drives the driven sprocket on the second end of the lead screw to rotate through the servo motor, which also drives the lead screw to rotate, and then based on the threaded cooperation between the lead screw and the telescopic sleeve, the rotation of the lead screw can be converted into the movement of the telescopic sleeve, thereby realizing the axial movement of the telescopic sleeve, that is, the telescopic function of the above-mentioned telescopic assembly can be realized; of course, the telescopic amount of the telescopic sleeve can be set by a program.

[0113] Furthermore, if Fig.11 As shown, the lifting platform 4 includes: a platform 41 and a lifting mechanism 42;

[0114] like Figure 3 As shown, the platform 41 is arranged below the mesh stretching mechanism 3, and a positioning and mounting structure for cooperating with the screen frame 6 is provided on the top thereof;

[0115] like Fig.10 As shown, the lifting mechanism 42 is disposed on the frame 1 , and its lifting end is connected and fixed to the bottom of the platform 41 .

[0116] It should be noted that the platform 41 and the lifting mechanism 42 are respectively the platform part and the lifting part of the lifting platform 4 as described above; wherein the platform 41 can be arranged below the stretching mechanism 3, and the positioning and mounting structure at the top thereof is used to position and install the screen frame 6, and the lifting mechanism 42 can be arranged at the top between the front and rear ends of the frame 1, and its lifting end can be moved in the vertical direction and connected and fixed to the bottom of the platform 41; as a preferred embodiment, Fig.11As shown, the lifting mechanism 42 can use multiple cylinders, and the multiple cylinders can be respectively arranged at the top between the front and rear ends of the frame 1 in the vertical direction, and the bottom of the platform 41 is connected and fixed to the free ends of the multiple cylinders; and the lifting platform 4 is designed in this way, so that the lifting platform 4 has the characteristics of simple structure and convenient lifting. Of course, the lifting mechanism 42 can also use an integrated lifting mechanism, such as a screw assembly arranged in the vertical direction, which will not be repeated here.

[0117] Specifically, Fig.10 As shown, the positioning installation structure includes:

[0118] A plurality of positioning and mounting blocks 411 are arranged on the top of the platform 41 and are used to contact and cooperate with different parts of the inner circumferential wall of the screen frame 6 one by one. Among them, after the inner circumferential wall of the screen frame 6 is installed to the plurality of positioning and mounting blocks 411 on the top of the platform 41, the plurality of positioning and mounting blocks 411 can be evenly distributed along the inner circumferential wall of the screen frame 6 (circular screen frame); of course, the inner circumferential wall of the screen frame 6 can also be clamped on the plurality of positioning and mounting blocks 411 on the top of the platform 41, and the positioning and mounting structure on the top of the platform 41 is designed in this way, which has the characteristics of simple structure and convenient positioning and installation. In addition, the present scheme can also adopt other positioning and mounting structures, such as an annular positioning and mounting groove opened on the top of the platform 41, and the annular positioning and mounting groove can be used to position and install the lower part of the screen frame 6. In addition, if Fig.10 As shown, a plurality of positioning and mounting structures may be provided on the top of the platform 41, and may be distributed along the longitudinal direction of the frame 1, so that it is convenient to position and install a plurality of screen frames 6, thereby enabling the production of a plurality of screens on the device, and the operating mechanism may be movable along the longitudinal direction on the frame 1, so as to facilitate the automatic completion of the gluing and trimming of the wire mesh and the screen frame 6 one by one, and of course, the wire mesh pulled into the frame 1 may complete the production of a plurality of screens, which helps to reduce the waste of wire mesh material scraps and reduce the cost of wire mesh materials.

[0119] In this solution, after the screen frame 6 contacts the wire mesh, the operating mechanism 5 is used to first inject glue and dry the inner and outer peripheries of the wire mesh and the screen frame 6 respectively, and then cut the wire mesh along the outer periphery of the screen frame 6.

[0120] Among them, after the screen frame 6 contacts with the wire mesh, the operating mechanism 5 can first inject glue and dry the inner peripheral edges of the wire mesh and the screen frame 6, and inject glue and dry the outer peripheral edges of the wire mesh and the screen frame 6, and then cut the wire mesh along the outer peripheral edge of the screen frame 6, that is, trim the wire mesh along the outer peripheral edge of the screen frame 6, which can make the gluing of the inner and outer peripheral edges of the wire mesh and the screen frame 6 faster, help to speed up the screen production process, and of course, it is also beneficial to ensure the gluing effect of the wire mesh and the screen frame 6.

[0121] Furthermore, if Figure 12 to Figure 14As shown, the operating mechanism 5 includes: a bracket 51, a first straight mechanism 52, a rotating frame assembly, a first fixed plate 53, a second fixed plate 54, a first glue dispensing and drying mechanism, a second glue dispensing and drying mechanism and a cutting mechanism;

[0123] like Fig.12 As shown, the first straight mechanism 52 is disposed at the top end of the bracket 51, and its straight end can move along the front-rear direction of the frame 1; that is, the straight end (movable end) of the first straight mechanism 52 can move along the longitudinal direction of the frame 1;

[0124] like Fig.12 As shown, the rotating frame assembly is disposed at the straight end of the first straight mechanism 52 through a support rod 55, and the rotating frame assembly can rotate around the vertical direction;

[0125] like Fig.13 As shown, the first fixing plate 53 and the second fixing plate 54 are respectively arranged on both sides of the bottom of the rotating frame assembly;

[0130] like Fig.12 As shown, the first straight mechanism 52 can use two straight units, and the two straight units can be respectively arranged at the top of the bracket 51 along the front and rear direction of the frame 1, that is, the straight ends of the two straight units can move along the front and rear direction of the frame 1, wherein each straight unit can use a ball screw assembly driven by a servo motor;

[0131] like Fig.12As shown, the rotating frame assembly can be arranged between the straight ends of the two straight monomers through two support rods 55, so as to facilitate the rotation of the frame assembly to move along the front-to-back direction of the frame 1 through the two straight monomers, and then facilitate the first glue dispensing and drying mechanism, the second glue dispensing and drying mechanism and the cutting mechanism to move along the front-to-back direction of the frame 1; wherein, as Fig.13 As shown, the rotating frame assembly includes: a gear shaft 514, a gear shaft seat 515 and a rotating frame 517. The gear shaft seat 515 can be set between the two support rods 55. The gear shaft 514 can be rotatable around the vertical direction and is set in the gear shaft seat 515 (having a gear shaft installation cavity). The gear shaft 514 is exposed on the upper part of the gear shaft seat 515 and is provided with a gear. The top of the gear shaft seat 515 can be provided with a motor ( Fig.12 The output shaft of the motor is provided with a gear, and the gear on the upper part of the gear shaft 514 and the gear on the motor output shaft can realize transmission matching through a transmission belt, that is, the gear shaft 514 is driven to rotate by the motor. Of course, the gear shaft seat 515 is equivalent to the bracket of the gear shaft assembly, and the rotating frame 517 is arranged at the lower end of the gear shaft 514, so as to rotate with the gear shaft 514; Fig.13 As shown, the first fixing plate 53 and the second fixing plate 54 are respectively arranged on two sides (front and rear sides) of the bottom of the rotating frame 517;

[0132] The first glue dispensing and drying mechanism is arranged on the first side (rear side) of the first fixed plate 53, and is driven by the rotating frame 517 to rotate one circle, so that the outer periphery of the wire mesh and the screen frame 6 can be glued and dried for one circle, that is, the outer periphery of the wire mesh and the screen frame 6 can be glued and dried for one circle;

[0133] The second glue-dispensing and drying mechanism is arranged on the first side (rear side) of the second fixed plate 54, and is driven to rotate for one circle by the rotating frame 517, so that the inner periphery of the wire mesh and the screen frame 6 can be glued and dried for one circle, that is, the inner periphery of the wire mesh and the screen frame 6 can be glued and dried for one circle; wherein, the spacing between the first glue-dispensing and drying mechanism and the second glue-dispensing and drying mechanism can be equal to the inner diameter of the screen frame 6 + the difference between the inner and outer ring radii, and the first glue-dispensing and drying mechanism and the second glue-dispensing and drying mechanism are driven to rotate by the rotating frame assembly, so that the outer periphery and the inner periphery of the wire mesh and the screen frame 6 can be glued and dried for one circle respectively;

[0134] The cutting mechanism is arranged on the second side (front side) of the first fixed plate 53, and is driven by the rotating frame 517 to rotate one circle, so that the portion of the wire mesh located outside the outer peripheral edge of the screen frame 6 can be trimmed one circle, and the portion of the wire mesh located outside the outer peripheral edge of the screen frame 6 can be trimmed one circle; of course, there can be a distance between the cutting mechanism and the first glue dispensing and drying mechanism;

[0135] In addition, the first straight mechanism can also be an XY translation mechanism, that is, its movable end can move along the front and rear directions (Y direction) and left and right directions (Y direction) of the frame 1 respectively, so that it is convenient for the rotating frame assembly to achieve longitudinal and lateral movement in the plane, thereby facilitating the rotating frame assembly to move to the center position of the screen frame 6.

[0136] That is to say, the operating mechanism 5 drives the glue dispensing drying mechanism and the cutting mechanism to rotate by rotating the assembly, and can realize the glue dispensing and drying of the inner and outer peripheries of the wire mesh and the screen frame 6 respectively, and after the inner and outer peripheries of the wire mesh and the screen frame 6 are glued, the part of the wire mesh located outside the outer periphery of the screen frame 6 can be trimmed for one circle, so that the wire mesh is glued to the screen frame and the wire mesh is cut more conveniently. Of course, the operating mechanism 5 is also a glue dispensing-drying-cutting operating mechanism, and the glue dispensing drying mechanism and the cutting mechanism are indirectly driven to move longitudinally through the first straight mechanism 52, so as to facilitate the alignment of the glue dispensing drying mechanism with the outer periphery or inner periphery of the screen frame 6, and facilitate the alignment of the cutting mechanism with the part of the wire mesh located outside the outer periphery of the screen frame 6. In addition, the first straight mechanism 52 can be controlled by a program, so as to drive the rotating frame assembly to move to the center facing the screen frame 6 and stop.

[0137] Furthermore, if Fig.13 As shown, the operating mechanism 5 further includes: a second straight-moving mechanism 56 and a third straight-moving mechanism 57;

[0138] like Fig.14 As shown, the second straight-moving mechanism 56 and the third straight-moving mechanism 57 are respectively arranged on both sides of the bottom of the rotating frame assembly, and their straight-moving ends can move along the front-rear direction of the frame 1;

[0139] The first fixing plate 53 is disposed at the straight-moving end of the second straight-moving mechanism 56;

[0140] The second fixing plate 54 is disposed at the straight-moving end of the third straight-moving mechanism 57 .

[0141] It should be noted that if Fig.14 As shown, the second straight-moving mechanism 56 and the third straight-moving mechanism 57 can be respectively arranged at the front and rear sides of the bottom of the rotating frame 517, and their straight-moving ends can be moved along the front and rear direction of the frame 1. The first fixed plate 53 and the second fixed plate 54 are arranged at the straight-moving ends of the second straight-moving mechanism 56 and the third straight-moving mechanism 57 one by one, so as to drive the first glue-dispensing and drying mechanism and the second glue-dispensing and drying mechanism to move toward or away from each other, thereby facilitating the first glue-dispensing and drying mechanism and the second glue-dispensing and drying mechanism to align with the outer periphery or inner periphery of the screen frame 6, so that the first glue-dispensing and drying mechanism and the second glue-dispensing and drying mechanism can be adapted to align with the outer periphery or inner periphery of the screen frames 6 of different sizes; of course, this also facilitates the alignment of the cutting mechanism with the part of the screen located outside the outer periphery of the screen frame 6. Among them, as Fig.14As shown, the second straight-moving mechanism 56 and the third straight-moving mechanism 57 can adopt a screw assembly driven by a motor, and the first fixed plate 53 and the second fixed plate 54 are also arranged at the movable end of the screw assembly.

[0142] In this scheme, if Fig.13 As shown, the first glue dispensing and drying mechanism and the second glue dispensing and drying mechanism both include: a first rotary cylinder 58, a glue dispensing component and a drying component;

[0143] The glue dispensing assembly at least comprises: a glue dispensing pen 59;

[0144] The drying component at least includes: a hot air nozzle 510;

[0145] like Fig.14 As shown, the first rotary cylinder 58 is disposed on a first side of the first fixed plate 53 or the second fixed plate 54, and its rotary end can rotate around the front-rear direction of the frame 1;

[0146] The glue dispensing pen 59 and the hot air nozzle 510 are respectively arranged at the rotating ends of the first rotating cylinder 58 along the vertical direction, and the glue dispensing pen 59 and the hot air nozzle 510 are adjacent to each other.

[0147] It should be noted that the glue dispensing pen 59 and the hot air nozzle 510 are arranged together at the rotating end of the first rotating cylinder 58 in the vertical direction, and the glue dispensing pen 59 and the hot air nozzle 510 are adjacently distributed. The glue dispensing pen 59 and the hot air nozzle 510 both have a folding station and an operating station that can be rotatably switched, so that the glue dispensing pen 59 and the hot air nozzle 510 can be folded and operated at the same time; wherein, when the glue dispensing pen 59 is at the folding station, the first rotating cylinder 58 drives the glue dispensing pen 59 to rotate upward to prevent residual glue from dripping and protect the pen tip of the glue dispensing pen 59. When the glue dispensing pen 59 is at the operating station, the first rotating cylinder 58 drives the glue dispensing pen 59 to rotate downward, and then drives the glue dispensing pen 59 to rotate one circle through the rotating frame assembly, so as to facilitate the implementation of glue dispensing on the inner periphery or outer periphery of the screen and the screen frame 6. Of course, after the glue dispensing pen 59 completes one circle of glue dispensing, the first rotating cylinder 58 can drive the glue dispensing pen 59 to rotate upward;

[0148] When the hot air nozzle 510 is in the folded position, that is, the first rotary cylinder 58 drives the hot air nozzle 510 to rotate upward to avoid blowing hot air to dry the inner periphery or outer periphery of the wire mesh and the sieve frame 6. When the hot air nozzle 510 is in the working position, that is, the first rotary cylinder 58 drives the hot air nozzle 510 to rotate downward, and blows hot air to dry the inner periphery or outer periphery of the wire mesh and the sieve frame 6 after gluing;

[0149] In addition, if Fig.13As shown, the dispensing assembly further includes: a dispensing pen controller 516 and a glue liquid box; wherein the glue liquid box and the dispensing pen controller 516 can be respectively arranged on a rotating frame 517, the liquid inlet of the dispensing pen controller 516 and the liquid outlet of the glue liquid box can be connected by a hose, and the liquid outlet and the liquid inlet of the dispensing pen 59 can be connected by a hose, so that it is convenient to control the liquid inlet amount of the dispensing pen 59 through the dispensing pen controller 516; in addition, as Fig.14 As shown, the drying component also includes an air heater 518, which can be set on the rotating frame 517. The air outlet of the air heater 518 and the air inlet of the hot air nozzle 510 can be connected by a hose, and the hot air nozzle 510 of the first glue dispensing drying mechanism and the second glue dispensing drying mechanism can share one air heater 518.

[0150] That is to say, the first glue dispensing and drying mechanism and the second glue dispensing and drying mechanism adopt the form of a glue dispensing pen 59 and a hot air nozzle 510 integrated at the rotating end of the first rotating cylinder 58, so that the glue dispensing pen 59 and the hot air nozzle 510 have both a folding station and an operating station, which makes it convenient for glue dispensing and drying to be carried out and folded simultaneously. Moreover, the glue dispensing component adopts the glue dispensing pen 59, and the drying component adopts the hot air nozzle 510, so that the first glue dispensing and drying mechanism and the second glue dispensing and drying mechanism have the characteristics of simple structure, convenient glue dispensing, and convenient drying.

[0151] Specifically, Fig.13 As shown, the cutting mechanism includes: a second rotary cylinder 511, a cutting blade holder 512 and a cutting blade 513;

[0152] The second rotary cylinder 511 is disposed on the second side of the first fixed plate 53, and its rotary end can rotate around the front-rear direction of the frame 1;

[0153] The cutting tool holder 512 is disposed at the rotating end of the second rotating cylinder 511;

[0154] The cutter 513 is disposed on the cutting blade frame 512 and can rotate around the frame 1 in the left-right direction relative to the cutting blade frame 512 .

[0155] It should be noted that the cutting tool holder 512 has a folding position and an operating position that can be rotatably switched. Fig.14As shown, when the cutting knife holder 512 is at the working position, the second rotating cylinder 511 drives the cutting knife holder 512 to rotate downward, which makes the cutter 513 face downward, which is convenient for cutting the part of the wire mesh located outside the outer peripheral edge of the screen frame 6. When the cutting knife holder 512 is at the retracted position, the second rotating cylinder 511 drives the cutting knife holder 512 to rotate upward, which makes the cutter 513 face upward, which is convenient for protecting the cutting knife holder 512 and also prevents the cutter 513 from hurting people or the wire mesh; of course, after the cutter 513 completes the cutting, the second rotating cylinder 511 will drive the cutting knife holder 512 to rotate upward; in addition, the cutter 513 can be rotated around the left and right directions (laterally) of the frame 1 and is arranged on the cutting knife holder 512, so that when the second straight-moving mechanism 56 drives the cutter 513 to move toward the center of the screen frame 6, as shown in FIG. Fig.16 As shown, the cutter 513 and the upper end surface of the screen frame 6 can be at an angle of about 30°, so that the cutter 513 can cut the part of the screen located outside the outer periphery of the screen frame 6 at an angle, which is suitable for the production requirements of the screen of the vibration screen in the lithium battery industry; of course, the cutter 513 and the glue pen 59 can be distributed at intervals; in addition, as Fig.15 As shown, the upper part of the cutter 513 can be set in the cutting tool holder 512 through a rotating shaft, wherein the rotating shaft can be rotatably set in the cutting tool holder 512 along the left and right direction (laterally) of the frame 1, and the upper part of the cutter 513 can be installed on the rotating shaft. When the second straight-moving mechanism 56 drives the cutter 513 to move toward the center of the screen frame 6, due to the obstruction of the outer periphery of the screen frame 6, the cutter 513 follows the rotating shaft to rotate until it presents an angle of about 30° with the upper end surface of the screen frame 6, and the movement of the cutter 513 can be stopped. Of course, a reset spring is also provided on the rotating shaft so that the cutter 513 can be elastically reset to a vertical position after it is separated from the outer periphery of the screen frame 6.

[0156] That is to say, the cutting mechanism adopts the form of a cutting body (including a cutting tool holder 512 and a cutter 513) arranged on a rotating cylinder, so that the cutting body can have a folding station and an operating station, which helps to improve the safety of the cutting mechanism, and the cutter 513 can be rotated in the left and right directions around the frame 1 relative to the cutting tool holder 512, so that the cutter 513 can achieve inclined cutting of the part of the wire mesh located outside the outer periphery of the screen frame 6, thereby meeting the production requirements of the vibrating screen in the lithium battery industry.

[0157] More specifically, when the operating mechanism 5 is operating, Fig.13As shown, the rotating frame 517 can rotate clockwise following the gear shaft 514, so as to implement one circle of gluing and one circle of drying on the inner and outer peripheries of the wire mesh and the screen frame 6 respectively. After the gluing and drying are completed, the first rotating cylinder 58 drives the gluing pen 59 and the hot air nozzle 510 to rotate to the folding position, and then the second rotating cylinder 511 drives the cutting tool holder 512 to rotate downward, and then the second straight-moving mechanism 56 drags the cutting tool holder 512 to move toward the center of the screen frame 6 until the cutter 513 forms an angle of about 30° with the upper end surface of the screen frame 6, and then the rotating frame 517 is rotated about 370°, so as to achieve inclined cutting of the part of the wire mesh located outside the outer periphery of the screen frame 6.
