DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] like Figures 1 to 3As shown, the embodiment of the present application discloses a parallel double-axis hot-melt cutting machine, comprising a frame 1, a placing frame 2 is arranged at the lower end of the frame 1, a first unwinding shaft 101 and a second unwinding shaft 102 are arranged on the placing frame 2, and a head material clamping translation mechanism 3, a hot-melt clamping and cutting mechanism 4 and a tail material clamping mechanism 5 are arranged in sequence at the upper end of the frame 1 from the inlet to the outlet; One end of the first unwinding shaft 101 and the second unwinding shaft 102 is a driving end, and the other end of the first unwinding shaft 101 and the second unwinding shaft 102 is a limiting end. The driving ends of the first unwinding shaft 101 and the second unwinding shaft 102 are both provided with a first driving gear 103, and a driving motor 104 is provided on the side of the frame 1 close to the driving end, and a second driving gear 105 is provided on the driving end of the driving motor 104. When the first unwinding shaft 101 or the second unwinding shaft 102 moves to the working position, the first driving gear 103 and the second driving gear 105 are meshed, and a limiting mechanism for limiting the limiting end and an unwinding shaft pushing mechanism 6 for pushing the second unwinding shaft 102 to the working position are respectively provided on the side of the frame 1 close to the limiting end; The frame 1 is also provided with a tailing detection mechanism 7 for detecting tailings.

[0030] During specific operation, the first unwinding shaft 101 is located at the working position, and the coil passes through the hot-melt clamping and cutting mechanism 4 and the tail material clamping mechanism 5 respectively and is transmitted forward under the drive of the driving motor 104, that is, through the meshing of the first driving gear 103 and the second driving gear 105, the first driving gear 103 rotates, thereby conveying the coil outward, and the second unwinding shaft 102 is located at the material inlet, and the material head of the second unwinding shaft 102 is clamped at the head material clamping translation mechanism 3, and 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 Drive 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, and the hot melt clamping and cutting mechanism 4 cuts the tail of the first roll of material. After cutting is completed, the hot melt clamping and cutting mechanism 4 is reset, and the head material clamping translation mechanism 3 drives the head material of the second roll of material 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 hot melt clamping and cutting mechanism 4 cuts the head of the second roll of material. After cutting is completed, the tail of the first roll of material and the head of the second roll of material are hot-melt-fused together by the hot melt clamping and cutting mechanism 4.

[0031] This structure can cut 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 point. At the same time, through the setting of the unwinding shaft pushing mechanism 6, the head material clamping translation mechanism 3 and the limiting mechanism, automatic non-stop loading can be realized, thereby reducing manual work while improving the production efficiency of the product.

[0032] In this embodiment, Fig.11 As shown, the unwinding shaft pushing mechanism 6 includes a front mounting plate 601 and a rear mounting plate mounted on the frame 1, and 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 also includes a rotating shaft driving motor 603 for driving the front rotating shaft 602 or the rear rotating shaft to rotate, and the front rotating shaft 602 and the rear rotating shaft are both provided with a rotating wheel 604, and also includes a belt 605, and the belt 605 is sleeved on the rotating wheel 604; It also includes a driving plate 606 installed on the belt 605, on which a first adjusting plate 607 is installed, and a second adjusting plate 608 installed on the first adjusting plate 607, wherein an arc structure is provided at the end of the first adjusting plate 607, and the end of the arc structure is a protrusion 609, and a mounting shaft 610 is provided on the second adjusting plate 608, and the mounting shaft 610 is located at the arc structure, and also includes a push block 611, and the push block 611 is composed of a pushing portion 612, a rotating mounting portion and a limiting portion 613 arranged in sequence from top to bottom, and the rotating mounting portion is rotatably connected to the mounting shaft 610, and the limiting portion 613 is an inwardly recessed groove, and the protrusion 609 of the first adjusting plate 607 is located in the limiting portion 613, and the weight of the limiting portion 613 is greater than the weight of the pushing portion 612.

[0033] Specifically, when loading without stopping the machine, the second unwinding shaft 102 will be pushed into the feeding port of the frame 1 first. During the pushing process, the push block 611 rotates counterclockwise along the rotating mounting portion, so that the second unwinding shaft 102 can enter the placement rack 2 through the push block 611. At this time, since the weight of the limiting portion 613 is greater than the weight of the pushing portion 612, the push block 611 rotates clockwise to return to the vertical state. At the same time, since the protrusion 609 of the first adjustment plate 607 is located in the limiting portion 613, the push block 611 cannot continue to rotate, thereby maintaining the vertical state. , then the shaft driving motor 603 drives the front rotating shaft 602 or the rotating wheel 604 on the rear rotating shaft to rotate, thereby causing the belt 605 to rotate, and then driving the driving plate 606 to move, thereby driving the pushing block 611 to push the second unwinding shaft 102 to move forward to the working position, so that the first driving gear 103 of the second unwinding shaft 102 is engaged with the second driving gear 105, and at the same time the second unwinding shaft 102 is limited by the limiting mechanism. At this time, the first unwinding shaft 101 is pushed out by the second unwinding shaft 102 to the discharge port of the frame 1, thereby realizing automatic loading operation.

[0034] In the present structure, waist-shaped grooves are provided on 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 cooperating with the positions of the bolts and the waist-shaped grooves, so that the push block 611 can better push the second unwinding shaft 102 to move. At the same time, the push block 611 is designed so that the weight of the limiting part 613 is greater than the weight of the pushing part 612 and the push block 611 is rotatable, so that on the one hand, the push block 611 will not hinder the second unwinding shaft 102 from entering the frame 1, and at the same time, the push block 611 can also be automatically reset, so that it can push the second unwinding shaft 102 to move.

[0035] In this embodiment, the limiting mechanism includes a support block 106 and a limiting arc block 107 which are correspondingly arranged above and below the working position, and also 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 shaft 101 or the second unwinding shaft 102 moves to the working position, the limiting end of the first unwinding shaft 101 or the second unwinding shaft 102 is limited between the arc block and the support block 106.

[0036] Specifically, when the first unwinding shaft 101 or the second unwinding shaft 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 shaft 101 or the second unwinding shaft 102 is limited between the arc block and the support block 106, so that the first unwinding shaft 101 or the second unwinding shaft 102 rotates under the action of the driving motor 104, so that the first unwinding shaft 101 or the second unwinding shaft 102 can discharge material outward.

[0037] 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 misplaced during operation.

[0038] In this embodiment, Figure 7 As shown, the head material clamping 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, the first clamping block 301 is sleeved with a first limit block 304 and a second limit block 305 that can slide on the first clamping block 301, the first limit block 304 is provided with a first locking knob for locking the first limit block 304 on the first clamping block 301, and the second limit block 305 is provided with a second locking knob for locking the second limit block 305 on the first clamping block 301; Both ends of the first clamping block 301 are also provided with horizontal driving cylinders 306 for driving the first clamping block 301 to move horizontally, and the horizontal driving cylinders 306 are installed on the frame 1; A scale 307 is disposed on the surface of the first clamping block 301 .

[0039] Specifically, when the material head of the second unwinding shaft 102 is clamped at the head material clamping and translation mechanism 3, first release the push-pull clamp 303, loosen the first locking knob and the second locking knob, and then adjust the positions of the first limit block 304 and the second limit block 305 according to the width of the coil in cooperation with the ruler 307, and then tighten the first locking knob and the second locking knob to 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 the second unwinding shaft 102 needs to be loaded, the horizontal driving cylinder 306 drives the first clamping block 301 to drive the head material of the second coil to pass through the hot melt clamping and cutting mechanism 4 to complete the loading operation.

[0040] The arrangement of this structure can realize automatic loading operation, and at the same time, the arrangement of the first limit block 304 and the second limit block 305 can realize the limitation of the material head clamping position of the second unwinding shaft 102, so that the clamping position of the material head is more accurate, so that after loading, the material head position and the material tail position of the previous roll can coincide with each other, and at the same time, the first limit block 304 and the second limit block 305 are adjustable structures, so they can be adjusted according to the width of the material head, so that this device can adapt to the use of rolls of various widths.

[0041] In this embodiment, Fig.10 As shown, the tail material clamping mechanism 5 comprises an upper clamping roller 501 and a lower clamping roller 502, both ends of the upper clamping roller 501 and the lower clamping roller 502 are respectively provided with a first clamping mounting plate 503 and a second clamping mounting plate, and both ends of the lower clamping roller 502 are respectively rotatably connected to the first clamping mounting plate 503 and the second clamping mounting plate; The first clamping mounting plate 503 is slidably connected to a first lifting plate 504, and further includes a third driving cylinder 505 for driving the first lifting plate 504 to perform lifting motion along the first clamping mounting plate 503. The first clamping mounting plate 503 is also provided with a rotation driving motor 506 for driving the lower clamping roller 502 to rotate; The second clamping mounting plate is slidably connected with a second lifting plate, and also includes a fourth driving cylinder for driving the second lifting plate to perform lifting motion along the second clamping mounting plate.

[0042] Specifically, when the tail material detection mechanism 7 detects that the first unwinding shaft 101 has unwound to the tail material, the tail material clamping mechanism 5 clamps the material roll of the first unwinding shaft 101, thereby preventing the material roll of the first unwinding shaft 101 from slipping, and when the tail material clamping operation is performed, 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 material roll, and when the material roll needs to be conveyed forward, the driving motor 506 is rotated to drive the lower clamping roller 502 to rotate, thereby realizing the forward conveying of the material roll.

[0043] In this structure, the tail material clamping mechanism 5 can prevent the tail material of the coil from slipping, and can also realize the slow forward conveyance of the tail material of the coil material.

[0044] In this embodiment, Figure 5 As shown, a receiving rack 201 is arranged at the bottom of the discharge end of the frame 1, a baffle 202 is arranged at the end of the receiving rack 201 away from the frame 1, a roller 203 is arranged at the bottom of the receiving rack 201, and the movement direction of the roller 203 is perpendicular to the movement direction from the feed port to the discharge port, and a buffer block 204 is arranged on the side of the baffle 202 facing the frame 1.

[0045] Specifically, when the second unwinding shaft 102 automatically loads the material, the first unwinding shaft 101 is pushed out to the storage rack 201 by the second unwinding shaft 102 . When the first unwinding shaft 101 is manually collected, the first unwinding shaft 101 can be taken out along the rolling direction of the roller 203 .

[0046] In this structure, the setting of the storage rack 201 can realize the material collection function for the empty unwinding shaft, wherein the setting of the baffle 202 can play a buffering role for the empty unwinding shaft, preventing the empty unwinding 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 unwinding shaft and reduce the direct friction between the empty unwinding shaft and the storage rack 201.

[0048] When the cutting clamping mechanism and the upper hot melt assembly 404 and the lower hot melt assembly 408 clamp the roll material at the same time, the tip of the cutting knife 406 contacts the roll material to be cut, and the cutting knife 406 is located between the cutting clamping mechanism and the upper hot melt assembly 404 and the lower hot melt assembly 408.

[0049] Specifically, 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 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, and the sixth driving cylinder 405 drives the upper hot melt component 404 to press down, and the seventh driving cylinder 411 drives the pressing block 410 to press down, and the tail of the first roll of material is pressed to between the cutting clamping mechanism and the upper hot melt component 404 and the lower hot melt component 408, and the cutting knife 406 cuts the tail of the first roll of material under the action of the cutting knife driving module. After cutting is completed, the upper hot melt component 404 and the pressing block 410 are reset, and the head The material 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, and the fifth driving cylinder 402 drives the upper hot melt component 404 and the cutting knife 406 to move 20-30mm toward the discharge port.

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 component 404 and the lower hot melt component 408 are heated to heat the tail of the first roll of material and the head of the second roll of material together.

[0050] In this structure, by setting the cutting knife 406, the head and tail of the coil can be cut before hot melting, so that the head and tail of the coil are in a flush state during hot melting, thereby ensuring the flatness of the welding point.

[0051] In this embodiment, Figure 3 As shown, a detection camera 8 is also provided on the upper part of the frame 1 , and the detection camera 8 is located between the hot melt clamping and cutting mechanism 4 and the tail material clamping mechanism 5 .

[0052] The rear end of this device may be connected to subsequent cutting equipment and punching equipment. When the hot melt is completed, the coil moves forward a set distance under the drive of the tail material clamping mechanism 5. The detection camera 8 detects the position of the weld and calculates whether the hot melt is located at the punching position after calculating the movement design distance. If so, the subsequent cutting equipment will pull the coil forward 30-50mm and cut it off, so as to avoid punching at the hot melt.

[0053] In this embodiment, Figure 3 As shown, the frame 1 is also provided with a support plate 9 for supporting the coil, and the support plate 9 is located between the hot melt clamping and cutting mechanism 4 and the tail material clamping mechanism 5; The frame 1 is provided with a third lifting plate 205 at the feed port, the third lifting plate 205 is provided with a support seat 206, the support seat 206 is provided with a positioning groove 207, the support seat 206 is provided with a blocking protrusion 208 on the side away from the frame 1, and also includes an eighth driving cylinder 209 for driving the third lifting plate 205 to perform lifting movement.

[0054] 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.

[0055] 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.

[0056] The present invention also discloses a parallel double-axis hot-melt cutting method, including the parallel double-axis hot-melt cutting machine described above. The specific method is that the first unwinding shaft 101 is located at the working position, and the coil material passes through the hot-melt clamping and cutting mechanism 4 and the tail material clamping mechanism 5 to be transmitted forward respectively, the second unwinding shaft 102 is located at the material inlet, and the material head of the second unwinding shaft 102 is clamped at the head material clamping translation mechanism 3. 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.

[0057] This method can achieve cutting of the head and tail of the product by setting up the hot melt clamping and cutting mechanism 4, thereby ensuring the flatness of the product at the hot melt location. At the same time, through the setting of the unwinding shaft pushing mechanism 6, the head material clamping translation mechanism 3 and the limiting mechanism, automatic non-stop loading can be achieved, thereby reducing manual work while also improving the production efficiency of the product.
