DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0027] Embodiment one

[0028] Please refer to Figures 1-6 A full-automatic double-side seal cutting machine, including seal cutting machine frame 1, be equipped with conveying belt 2, side seal cutting knife holder 3 and horizontal seal cutting die 4 on seal cutting machine frame 1, still be equipped with the corner cutting mechanism 5 of cooperation horizontal seal cutting die 4 use on seal cutting machine frame 1,

[0029] Corner cutting mechanism 5 includes the bottom plate 501 of being equipped with on seal cutting machine frame 1, two hydraulic cylinders 505 of being set up on one side of bottom plate 501 and two guide columns 502 of being set up on bottom plate 501, the sliding block 503 of being equipped with on guide column 502, and the telescopic end of two hydraulic cylinders 505 is fixedly connected between two sliding blocks 503 respectively, and the beveling cutter die 504 of being equipped with on the sliding block 503 below rotation, and the adjusting assembly 6 for adjusting the angle of beveling cutter die 504 of being equipped with on sliding block 503.

[0030] The traditional sealing machine uses thermoplastic film to wrap the material, which will form sharp corner protrusions at the four corners of the material. If the thickness of the material is greater than the shrinkage limit of the thermoplastic film, the thermoplastic sealed material corners will naturally shrink, and the thermoplastic film protrusions at the corners will be tightly attached to the edge of the material. However, when the thickness of the material is small, the four corner protrusions of the thermoplastic sealed material will be raised at the corners of the material. In order to reduce this situation, the existing technology prolongs the time of the material passing through the thermoplastic machine or increases the temperature around the four corners to allow the heat shrink film to shrink more evenly. This situation more or less affects the production efficiency of the production line. In order to speed up the continuity and production efficiency of the sealing machine, the utility is provided with a corner cutting mechanism 5 between the transverse sealing cutter die 4 and the thermoplastic machine. The corner cutting mechanism 5 forcibly cuts off the corner protrusions of the thermoplastic film, and after cutting, it will not affect the integrity of the thermoplastic film, so that the material with the removed corner protrusions can be thermoplastic faster, thereby speeding up the entire production speed.

[0031] The specific working principle of the corner cutting mechanism 5 is that the material passing through the transverse sealing cutter die 4 will pass under the two bevel cutting die 504 of the corner cutting mechanism 5. The two hydraulic cylinders 505 work to drive the two bevel cutting die 504 to move downward, thereby cutting the thermoplastic film corners of the material head. Then, when the material passes through the transverse sealing cutter die 4, the material continues to advance and passes through the corner cutting mechanism 5. At this time, the setting angle of the two bevel cutting die 504 is adjusted by the adjusting assembly 6, so that the angle between the two bevel cutting die 504 and the initial position is 90° difference. Finally, the thermoplastic film corners of the material tail are cut by the driving of the hydraulic cylinder 505, and the cutting of the thermoplastic film corners of the material four corners is finally completed. This cutting can ensure the integrity of the thermoplastic film, and after reducing the heat shrinkage degree of the heat shrink film, the phenomenon of four corner protrusions of the material after thermoplastic can be eliminated.

[0032] Embodiment two

[0033] Please refer to Figures 4-5 The present embodiment is basically the same as embodiment one, and is made on the basis of embodiment one and has the same beneficial effects as embodiment one. For the same parts, please refer to each other. Here, it will not be described in detail.

[0034] As a further technical solution of the present embodiment, the bevel cutting die 504 comprises a rotating shaft 5041 rotatably arranged on the sliding block 503, the rotating shaft 5041 is provided with a mounting plate 5042, the mounting plate 5042 is provided with a cutting knife 5043, and the mounting plate 5042 is further provided with two housings 5044, the housings 5044 are slidably provided with limiting blocks 5045 matched with the cutting knife 5043, and the housings 5044 are further provided with extrusion springs 5046 for extruding the limiting blocks 5045.

[0035] Further, the single rotation angle of the bevel cutting die 504 is 90°.

[0036] Further, the bottom plate 501 is provided with a "cross" heating block for cooperating with the bevel cutting die 504.

[0037] As can be seen from the above, the bevel cutting die 504 is generally composed of a rotating shaft 5041, a mounting plate 5042, a cutting knife 5043 and a limiting block 5045, and the shell 5044 and the compression spring 5046 are arranged to ensure that the limiting block 5045 first contacts the "cross" heating block, thereby completing the edge sealing of the thermoplastic film;

[0038] When the bevel cutting die 504 falls as a whole, the two sliding limiting blocks 5045 and the cutting knife 5043 fall at the same time, and when the two limiting blocks 5045 contact the "cross" heating block, the cutting knife 5043 is also positioned directly above the corner of the thermoplastic film. After the edge sealing of the corner of the thermoplastic film is completed, the bevel cutting die 504 continues to fall, at which time the cutting knife 5043 falls and contacts the "cross" heating block, thereby completing the cutting of the thermoplastic film at the corner of the material. The two sliding limiting blocks 5045 will slide upward, and the entire process is simple and fast. When the bevel cutting die 504 is moved upward after cutting is completed, the two limiting blocks 5045 return to the initial state under the action of the compression spring 5046;

[0039] The angle between the bevel cutting die 504 and the horizontal sealing and cutting die 4 is 45° when the bevel cutting die 504 is in the initial position. After the setting angle of the bevel cutting die 504 is changed by the adjusting assembly 6, the angle between the bevel cutting die 504 and the horizontal sealing and cutting die 4 is 135°. This setting can make the thermoplastic film at the corner of the material form a chamfering effect after cutting, which is more consistent with the thermal shrinkage film tension during thermoplastic, so that the thermoplastic film is tightly attached to the corner of the material.

[0040] Example Three

[0041] Please refer to Figures 2-6 This embodiment is basically the same as example one, and is made on the basis of example one and has the same beneficial effects as example one. For the same parts, please refer to each other, which will not be described in detail here

[0042] As a further technical solution of this embodiment, the adjusting assembly 6 includes a driving shaft 601 rotatably arranged in the sliding block 503 and a worm 602, and the driving shaft 601 and the worm 602 are arranged in parallel.

[0043] The driving shaft 601 is provided with a driven gear 603, the guide column 502 is provided with a rack for cooperating with the driven gear 603, and the driving shaft 601 is connected with a transmission gear A 604 at one end outside the sliding block 503 through a one-way bearing 6011.

[0044] The rotating shaft 5041 is provided with a worm wheel 605, the worm 602 is engaged with the worm wheel 605, and the worm 602 is provided with a transmission gear B 606 at one end outside the sliding block 503, and the transmission gear A 604 is engaged with the transmission gear B 606.

[0045] Further, the guide column 502 and the sealing and cutting machine rack 1 are fixedly connected through a reinforcing plate.

[0046] Further, the sliding block 503 is provided with a sealing shell matched with the transmission gear A 604 and the transmission gear B 606.

[0047] As can be seen from the above, the function of the adjusting assembly 6 is to adjust the setting angle of the bevel cutting die 504, so as to better cut off the thermoplastic film at the corner. The specific working principle is as follows: after the bevel cutting die 504 in the initial state is moved downward to cut off the thermoplastic film at the head of the material, the hydraulic cylinder 505 works to drive the entire sliding block 503 to move upward to reset. When the sliding block 503 returns to the initial state, the sliding block 503 continues to move upward under the drive of the hydraulic cylinder 505, which causes the driven gear 603 arranged in the sliding block 503 to be engaged with the rack on the guide column 502, thereby realizing the rotation of the driving shaft 601. Since the driving shaft 601 is connected with the transmission gear A 604 through the one-way bearing 6011 at one end outside the sliding block 503, the upward movement of the sliding block 503 will cause the driving shaft 601 to rotate and drive the transmission gear A 604 to rotate, that is, drive the transmission gear B 606 to rotate. Since the worm 602 is fixedly connected with the transmission gear B 606, the worm 602 can rotate with the upward movement of the sliding block 503, further driving the worm wheel 605 to rotate, that is, driving the rotating shaft 5041 to rotate, thereby realizing the posture adjustment of the entire bevel cutting die 504 when the sliding block 503 moves upward.

[0048] When the bevel cutting die 504 rotates by 90°, the hydraulic cylinder 505 works to drive the sliding block 503 to move downward. The downward movement of the sliding block 503 will drive the driven gear 603 to rotate, that is, drive the driving shaft 601 to rotate. However, since the one-way bearing 6011 is arranged between the driving shaft 601 and the transmission gear A 604, the driving shaft 601 will not rotate when the sliding block 503 moves downward, which can prevent the bevel cutting die 504 from returning to the unadjusted posture after the angle adjustment.

[0049] The driving of the whole adjusting assembly 6 is powered by the hydraulic cylinder 505, when the hydraulic cylinder 505 drives the beveling die 504 to cut downward, the angle of the beveling die 504 does not change, when the hydraulic cylinder 505 drives the beveling die 504 to move upward, the cutting angle of the beveling die 504 can be adjusted through the adjusting assembly 6, the whole structure is compact, does not need additional power or control system, is high in integration, and is suitable for being installed in an existing cutting machine.

[0050] The control mode of the utility model is automatically controlled through the controller, the control circuit of the controller can be realized through simple programming of the person skilled in the art, the provision of the power supply also belongs to the public knowledge in the art, and the utility model is mainly used for protecting the mechanical device, therefore the utility model will not explain the control mode and the circuit connection in detail.
