Description

Technical Field

[0001] The present invention relates to the field of cutting equipment, and particularly to a parallel double-axis hot melt cutting machine. Background Art

[0002] EVA (short for ethylene-vinyl acetate copolymer) film is an important component of photovoltaic cells. Its function is to paste the cells of photovoltaic cell modules on the bottom plate and paste tempered glass on the cells. EVA film is often used in rolls. When in use, the rolled EVA film is cut into thin sheets equivalent to the area of photovoltaic cell modules.

[0003] Existing EVA film cutting machines still have some deficiencies. For example, Chinese Patent No. 202211208789.0 discloses a hot melt cutting machine and its cutting method, which includes a first frame and a second frame. The second frame is located on one side of the first frame. A hot melt feeding mechanism for feeding materials is arranged on the first frame. A feeding and cutting mechanism for pulling and cutting materials, a pressing mechanism for pressing materials, and a pulling mechanism for pulling materials to a specified length are arranged on the second frame. The hot melt feeding mechanism, the feeding and cutting mechanism, the pressing mechanism, and the pulling mechanism are arranged in sequence. A discharging mechanism is also arranged below the pressing mechanism and the pulling mechanism on the second frame. When working, when a roll of material reaches the end of the material, it is necessary to manually remove the air shaft, install a new material roll, feed the new material roll, and pull the head of the new material roll through the head pressing component and overlap it on the tail of the previous material, that is, the connection part of the two material rolls needs to be manually overlapped. However, there are problems such as uneven overlapping parts and inconvenient overlapping for large material rolls in manual overlapping. Summary of the Invention

[0045] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be given in conjunction with the accompanying drawings.

[0046] As Figures 1 to 3 shown, the embodiment of the present application discloses a parallel double-axis hot melt cutting machine, including a frame 1. A placement rack 2 is provided at the lower end of the frame 1. A first unwind reel 101 and a second unwind reel 102 are provided on the placement rack 2. At the upper end of the frame 1, a head material clamping and translation mechanism 3, a hot melt clamping and cutting mechanism 4, and a tail material clamping mechanism 5 are sequentially arranged from the feeding port to the discharging port direction;

[0047] One end of the first unwind reel 101 and the second unwind reel 102 is the driving end, and the other end of the first unwind reel 101 and the second unwind reel 102 is the limiting end. First driving gears 103 are provided at the driving ends of the first unwind reel 101 and the second unwind reel 102. A driving motor 104 is provided on one side of the frame 1 close to the driving end. A second driving gear 105 is provided at the driving end of the driving motor 104. When the first unwind reel 101 or the second unwind reel 102 moves to the working position, the first driving gear 103 and the second driving gear 105 are engaged. A limiting mechanism for limiting the limiting end and a reel pushing mechanism 6 for pushing the second unwind reel 102 to the working position are respectively provided on one side of the frame 1 close to the limiting end;

[0048] A tail material detection mechanism 7 for detecting the tail material is further provided on the frame 1.

[0049] During specific operation, the first unwind reel 101 is in the working position. The coil material passes through the hot melt clamping and cutting mechanism 4 and the tail material clamping mechanism 5 respectively and is transported forward under the drive of the driving motor 104. That is, through the engagement of the first driving gear 103 and the second driving gear 105, the first driving gear 103 rotates, thereby feeding out the coil material. The second unwind reel 102 is located at the feeding port. The material head of the second unwind reel 102 is clamped at the head material clamping and translation mechanism 3. When the tail material detection mechanism 7 detects that the first unwind reel 101 unwinds to the tail material, the tail material clamping mechanism 5 clamps the coil of the first unwind reel 101. The tail material clamping mechanism 5 rotates and drives the material tail of the first coil in the first unwind reel 101 to move forward, so that the material tail moves to the hot melt clamping and cutting mechanism 4. The hot melt clamping and cutting mechanism 4 cuts the material tail of the first coil. After the cutting is completed, the hot melt clamping and cutting mechanism 4 resets. The head material clamping and translation mechanism 3 drives the material head of the second coil in the second unwind reel 102 to pass through the hot melt clamping and cutting mechanism 4. The reel pushing mechanism 6 pushes the second unwind reel 102 to the working position. The hot melt clamping and cutting mechanism 4 cuts the material head of the second coil. After the cutting is completed, the material tail of the first coil and the material head of the second coil are hot melted together by the hot melt clamping and cutting mechanism 4.

[0050] This structure can realize the cutting of the head and tail of the product through the setting of the hot-melt clamping and cutting mechanism 4, so as to ensure the flatness of the product at the hot-melt part. At the same time, through the setting of the unwind reel pushing mechanism 6, the head material clamping and translation mechanism 3 and the limiting mechanism, automatic feeding without stopping the machine can be realized, thus reducing manual work and improving the production efficiency of the product.

[0051] In this embodiment, as Figure 11 shown, the unwind reel pushing mechanism 6 includes a front mounting plate 601 and a rear mounting plate installed on the frame 1. The front mounting plate 601 and the rear mounting plate are both rotatably connected with a front rotating shaft 602 and a rear rotating shaft, and further includes a rotating shaft driving motor 603 for driving the rotation of the front rotating shaft 602 or the rear rotating shaft. The front rotating shaft 602 and the rear rotating shaft are both provided with runners 604, and further includes a belt 605. The belt 605 is sleeved on the runners 604;

[0052] It further includes a driving plate 606 installed on the belt 605. A first adjusting plate 607 is installed on the driving plate 606. A second adjusting plate 608 is further installed on the first adjusting plate 607. The end of the first adjusting plate 607 is provided with an arc structure, and the end of the arc structure is a protruding part 609. An installation shaft 610 is provided on the second adjusting plate 608, and the installation shaft 610 is located at the arc structure. A push block 611 is further included. The push block 611 is composed of a pushing part 612, a rotating installation part and a limiting part 613 arranged from top to bottom. The rotating installation part is rotatably connected with the installation shaft 610. The limiting part 613 is an inwardly concave groove, and the protruding part 609 of the first adjusting plate 607 is located in the limiting part 613. The weight of the limiting part 613 is greater than the weight of the pushing part 612.

[0053] Specifically, when loading materials without stopping the machine, first, the second unwinding reel 102 is pushed into the feeding port of the machine frame 1. During the pushing process, the pushing block 611 rotates counterclockwise along the rotating mounting part, so that the second unwinding reel 102 can enter the placing rack 2 through the pushing block 611. At this time, since the weight of the limiting part 613 is greater than that of the pushing part 612, the pushing block 611 rotates clockwise and returns to the vertical state. At the same time, since the protruding part 609 of the first adjusting plate 607 is located within the limiting part 613, the pushing block 611 cannot continue to rotate, thus maintaining the vertical state. Then, the rotating shaft driving motor 603 drives the runner 604 on the front rotating shaft 602 or the rear rotating shaft to rotate, so that the belt 605 rotates, and further drives the driving plate 606 to move, thereby driving the pushing block 611 to push the second unwinding reel 102 forward to the working position, so that the first driving gear 103 of the second unwinding reel 102 meshes with the second driving gear 105. At the same time, the second unwinding reel 102 is limited by the limiting mechanism. At this time, the first unwinding reel 101 is pushed out to the discharging port of the machine frame 1 by the second unwinding reel 102, thus realizing the automatic feeding operation.

[0054] In this structure, waist-shaped slots are provided on both the driving plate 606 and the first adjusting plate 607, so that the positions of the first adjusting plate 607 and the second adjusting plate 608 can be adjusted by the cooperation of the bolts and the positions of the waist-shaped slots, so that the pushing block 611 can better push the second unwinding reel 102 to move. At the same time, the pushing block 611 is designed in such a form that the weight of the limiting part 613 is greater than that of the pushing part 612 and the pushing block 611 can rotate. Thus, on the one hand, the pushing block 611 will not block the entry of the second unwinding reel 102 into the machine frame 1, and at the same time, the automatic reset of the pushing block 611 can be realized, enabling it to play the role of pushing the second unwinding reel 102 to move.

[0055] In this embodiment, the limiting mechanism includes a support block 106 and a limiting arc block 107 arranged corresponding to each other up and down at the working position, and further includes a first driving cylinder 108 for driving the limiting arc block 107 to move downward and a second driving cylinder 109 for driving the support block 106 to move upward. When the first unwinding reel 101 or the second unwinding reel 102 moves to the working position, the limiting end of the first unwinding reel 101 or the second unwinding reel 102 is limited between the arc block and the support block 106.

[0056] Specifically, when the first unwinding reel 101 or the second unwinding reel 102 is pushed to the working position, the second driving cylinder 109 drives the support block 106 to move upward, and at the same time, the first driving cylinder 108 drives the limiting arc block 107 to move downward, so that the limiting end of the first unwinding reel 101 or the second unwinding reel 102 is limited between the arc block and the support block 106, so that the first unwinding reel 101 or the second unwinding reel 102 rotates under the action of the driving motor 104, so that the first unwinding reel 101 or the second unwinding reel 102 can unwind materials outward.

[0057] In this structure, the support block 106 and the limiting arc block 107 can limit the first unwinding shaft 101 or the second unwinding shaft 102 to prevent the first unwinding shaft 101 or the second unwinding shaft 102 from being misaligned during operation.

[0058] In this embodiment, as Figure 7 shown, the head material clamping and translation mechanism 3 includes a first clamping block 301 and a second clamping block 302. The two ends of the first clamping block 301 and the second clamping block 302 are connected by a push-pull clamp 303. A first limiting block 304 and a second limiting block 305 that can slide on the first clamping block 301 are sleeved on the first clamping block 301. A first locking knob for locking the first limiting block 304 on the first clamping block 301 is arranged on the first limiting block 304, and a second locking knob for locking the second limiting block 305 on the first clamping block 301 is arranged on the second limiting block 305;

[0059] Two ends of the first clamping block 301 are further provided with a horizontal driving cylinder 306 for driving the first clamping block 301 to move horizontally. The horizontal driving cylinder 306 is installed on the frame 1;

[0060] A scale 307 is arranged on the surface of the first clamping block 301.

[0061] Specifically, when clamping the material head of the second unwinding shaft 102 at the head material clamping and translation mechanism 3, first loosen the push-pull clamp 303, loosen the first locking knob and the second locking knob, then adjust the positions of the first limiting block 304 and the second limiting block 305 according to the width of the rolled material in cooperation with the scale 307, then tighten the first locking knob and the second locking knob, pass the material head of the second unwinding shaft 102 through the gap between the first clamping block 301 and the second clamping block 302, and then pull the push-pull clamp 303 so that the material head is clamped between the first clamping block 301 and the second clamping block 302. When feeding the second unwinding shaft 102 is required, the horizontal driving cylinder 306 drives the first clamping block 301 to drive the material head of the second rolled material through the hot melt clamping and cutting mechanism 4 to complete the feeding operation.

[0062] The setting of this structure can realize the automatic feeding operation. At the same time, the setting of the first limiting block 304 and the second limiting block 305 can realize the limitation of the clamping position of the material head of the second unwinding shaft 102, making the clamping position of the material head more accurate, so that after feeding, the position of the material head and the position of the material tail of the previous roll can coincide. At the same time, the first limiting block 304 and the second limiting block 305 are adjustable structures, so they can be adjusted according to the width of the material head, so that this device can be adapted to use various rolled materials with different widths.

[0063] In this embodiment, as Figure 10 shown, the tail stock clamping mechanism 5 includes an upper clamping roller 501 and a lower clamping roller 502. First clamping mounting plates 503 are respectively arranged at both ends of the upper clamping roller 501 and the lower clamping roller 502, and second clamping mounting plates are respectively arranged at both ends of the lower clamping roller 502. Both ends of the lower clamping roller 502 are rotatably connected to the first clamping mounting plates 503 and the second clamping mounting plates respectively;

[0064] A first lifting plate 504 is slidably connected to the first clamping mounting plate 503. A third driving cylinder 505 for driving the first lifting plate 504 to move up and down along the first clamping mounting plate 503 is further included. A rotation driving motor 506 for driving the lower clamping roller 502 to rotate is further arranged on the first clamping mounting plate 503;

[0065] A second lifting plate is slidably connected to the second clamping mounting plate. A fourth driving cylinder for driving the second lifting plate to move up and down along the second clamping mounting plate is further included.

[0066] Specifically, when the tail stock detection mechanism 7 detects that the first unwinding shaft 101 unwinds to the tail stock, the tail stock clamping mechanism 5 clamps the coil on the first unwinding shaft 101, thereby preventing the coil on the first unwinding shaft 101 from slipping. When performing the tail stock clamping operation, the third driving cylinder 505 and the fourth driving cylinder synchronously drive the first lifting plate 504 and the second lifting plate to descend, so that the upper clamping roller 501 and the lower clamping roller 502 clamp the coil. When it is necessary to convey the coil forward, the rotation driving motor 506 drives the lower clamping roller 502 to rotate, thereby realizing the forward conveyance of the coil.

[0067] In this structure, the setting of the tail stock clamping mechanism 5 can, on the one hand, prevent the tail stock of the coiled material from slipping, and on the other hand, can also realize the slow forward conveyance of the tail stock of the coiled material.

[0068] In this embodiment, as Figure 5 shown, a receiving frame 201 is arranged at the bottom of the discharging end of the frame 1. A baffle 202 is arranged at one end of the receiving frame 201 away from the frame 1. A roller 203 is arranged at the bottom of the receiving frame 201. The moving direction of the roller 203 is perpendicular to the moving direction from the feeding port to the discharging port. A buffer block 204 is arranged on the side of the baffle 202 facing the frame 1.

[0069] Specifically, when the second unwinding shaft 102 automatically feeds the material, the first unwinding shaft 101 is pushed out to the receiving frame 201 by the second unwinding shaft 102. When manually collecting the first unwinding shaft 101, the first unwinding shaft 101 can be taken out along the rolling direction of the roller 203.

[0070] In this structure, the setting of the storage rack 201 can achieve the function of collecting empty winding shafts. Among them, the setting of the baffle 202 can play a buffering role for the empty winding shaft to prevent the empty winding shaft from directly colliding with the storage rack 201. At the same time, the setting of the roller 203 can facilitate the removal of the empty winding shaft and reduce the direct friction between the empty winding shaft and the storage rack 201.

[0071] In this embodiment, as Figure 8 and Figure 9 shown, the hot melt clamping and cutting mechanism 4 includes an upper moving plate 401 slidably connected to the frame 1, and further includes a fifth driving cylinder 402 for driving the upper moving plate 401 to move horizontally along the frame 1. An upper cross beam 403 is fixedly connected to the upper moving plate 401. An upper hot melt assembly 404 is arranged on one side of the upper cross beam 403. A sixth driving cylinder 405 for driving the upper hot melt assembly 404 to move up and down is arranged on the upper cross beam 403. A cutting knife 406 is arranged on one side of the upper hot melt assembly 404, and further includes a cutting knife driving module for driving the cutting knife 406 to move horizontally. The moving direction of the cutting knife 406 is perpendicular to the winding movement direction of the first winding shaft 101;

[0072] A lower hot melt assembly 408 corresponding to the upper hot melt assembly 404 is further arranged on the frame 1. A cutting and clamping mechanism is arranged on one side of the lower hot melt assembly 408;

[0073] The cutting and clamping mechanism includes a support frame 409. A pressing block 410 is arranged above the support frame 409, and further includes a seventh driving cylinder 411 for driving the pressing block 410 to move towards the support frame 409.

[0074] When the cutting and clamping mechanism clamps the winding material simultaneously with the upper hot melt assembly 404 and the lower hot melt assembly 408, the tip of the cutting knife 406 contacts the winding material to be cut, and the cutting knife 406 is located between the cutting and clamping mechanism, the upper hot melt assembly 404 and the lower hot melt assembly 408.

[0075] Specifically, when the tail stock detection mechanism 7 detects that the first unwinding shaft 101 unwinds to the tail stock, the tail stock clamping mechanism 5 clamps the material roll of the first unwinding shaft 101. The tail stock clamping mechanism 5 rotates and drives the tail of the first roll of material in the first unwinding shaft 101 to move forward, so that the tail of the material moves to the hot melt clamping and cutting mechanism 4. The sixth driving cylinder 405 drives the upper hot melt assembly 404 to press down, and the seventh driving cylinder 411 drives the pressing block 410 to press down. The tail of the first roll of material is pressed between the cutting and clamping mechanism, the upper hot melt assembly 404 and the lower hot melt assembly 408. The cutting knife 406 cuts the tail of the first roll of material under the action of the cutting knife driving module. After the cutting is completed, the upper hot melt assembly 404 and the pressing block 410 reset. The head stock clamping and translation mechanism 3 drives the head of the second roll of material in the second unwinding shaft 102 to pass through the hot melt clamping and cutting mechanism 4. The fifth driving cylinder 402 drives the upper hot melt assembly 404 and the cutting knife 406 to move 20 - 30 mm in the direction of the material outlet. The sixth driving cylinder 405 drives the upper hot melt assembly 404 to press down, and the seventh driving cylinder 411 drives the pressing block 410 to press down. The head of the second roll of material is pressed between the cutting and clamping mechanism, the upper hot melt assembly 404 and the lower hot melt assembly 408. The cutting knife 406 cuts the head of the second roll of material under the action of the cutting knife driving module. After the cutting is completed, the upper hot melt assembly 404 and the lower hot melt assembly 408 are heated to melt the tail of the first roll of material and the head of the second roll of material together.

[0076] In this structure, through the setting of the cutting knife 406, the head and tail of the rolled material can be cut before hot melting, so that the head and tail of the rolled material are in a flush state during hot melting, and thus the flatness of the welding joint can be ensured.

After the hot melting is completed, under the drive of the tail stock clamping mechanism 5, the rolled material moves forward a set distance. The detection camera 8 detects the position of the welding joint, and after calculating the designed movement distance, it determines whether the hot melting position will be at the punching position. If so, the subsequent cutting equipment will pull the rolled material forward by 30 - 50 mm and cut it off, so as to avoid punching at the hot melting position.

[0081] Specifically, when new material is loaded, the eighth drive cylinder 209 drives the third lifting plate 205 to descend, and an external forklift places the new coil on the support block 106, and then the eighth drive cylinder 209 drives the third lifting plate 205 to rise, and the new coil is manually pushed onto the placement rack 2.

[0082] In this structure, through the setting of the third lifting plate 205, the external docking equipment can conveniently deliver new coils into the frame 1. The setting of the positioning groove 207 and the blocking protrusion 208 can prevent the coil placed on the support seat 206 from falling. At the same time, the setting of the support plate 9 can support the coil in motion.

When the tail material detection mechanism 7 detects that the first unwinding shaft 101 unwinds to the tail material, the tail material clamping mechanism 5 clamps the material roll of the first unwinding shaft 101, and the tail material clamping mechanism 5 rotates and drives the tail of the first coil material in the first unwinding shaft 101 to move forward, so that the tail material moves to the hot-melt clamping and cutting mechanism 4, the upper hot-melt component 404 is pressed down, and the pressing block 410 is pressed down, and the tail of the first coil material is pressed to the cutting clamping mechanism and between the upper hot-melt component 404 and the lower hot-melt component 408, and the cutting knife 406 is in the cutting The tail of the first coil is cut under the action of the cutter driving module. After the cutting is completed, the upper hot melt component 404 and the pressing block 410 are reset, and the head material clamping translation mechanism 3 drives the head material of the second coil in the second unwinding shaft 102 to pass through the hot melt clamping and cutting mechanism 4, and the unwinding shaft pushing mechanism 6 pushes the second unwinding shaft 102 to the working position, and the fifth driving cylinder 402 drives the upper hot melt component 404 and the cutting knife 406 to move 20-30mm in the direction of the discharge port, and the upper hot melt component 404 is pressed down, and the pressing block 410 is pressed down, and the head of the second coil is pressed to the cutting clamping mechanism and the upper hot melt component 404 and the lower hot melt component 408. The cutting knife 406 cuts the head of the second coil under the action of the cutting knife driving module. After the cutting is completed, the upper hot melt component 404 and the lower hot melt component 408 are heated to heat the tail of the first coil and the head of the second coil together.

[0084] This method can achieve the cutting of the head and tail of the product through the setting of the hot melt clamping and cutting mechanism 4, so as to ensure the flatness of the product at the hot melt part.
