Description

Technical Field

[0001] The utility model relates to the field of film stripping mechanisms, in particular to a die-cutting and stripping device and a pin-hole machine. Background Art

[0002] When extracting the base film of the raw material with films on both sides, a direct tearing method is usually adopted. In the related technology, a mounting seat is movably arranged on the machine table, a movable slide rail is arranged on the mounting seat, and the stripping knife assembly is locked on the movable slide rail by bolt connection to press against the base film. During the operation of the equipment, the stripping knife assembly always presses against the base film. Thus, force is applied to the separation point of the base film, so that the films on both sides can be separated more stably.

[0003] When this type of die-cutting and stripping device is actually used, the stripping knife assembly is locked on the movable slide rail by bolt connection. Therefore, the bolts can only be loosened before the device is operated so that the stripping knife assembly can slide on the movable slide rail. After determining the locking position of the stripping knife assembly on the movable slide rail, the bolts can be tightened. After the device is operated, the stripping knife assembly cannot slide on the movable slide rail. The stripping knife assembly is always pressed against the base film to achieve the separation effect. Therefore, when this type of die-cutting and stripping device separates products of different specifications from the base film, it is necessary to continuously determine the position of the stripping knife assembly on the movable slide rail through manual adjustment after stopping the machine, which will consume time and energy, resulting in low production capacity and not conducive to mass production.

[0035] refer to Figure 1 and Figure 4 According to some embodiments of the present invention, the die-cutting and stripping device includes: a stripping knife assembly 100, a position adjustment assembly 200 and a sensor assembly 300.

[0036] refer to Figure 1 and Figure 3, the stripping knife assembly 100 is used to separate the product from the base film; the position adjustment assembly 200 includes a motor 210, a bidirectional screw rod 220 and a mounting frame 230, the motor 210 is connected to the mounting frame 230, the bidirectional screw rod 220 is rotatably connected to the stripping knife assembly 100, the motor 210 drives the bidirectional screw rod 220 to rotate the bidirectional screw rod 220 so that the stripping knife assembly 100 slides on the bidirectional screw rod 220; the sensing assembly 300 includes a sensor 301 and a shading sheet 302, the sensor 301 is arranged on the mounting frame 230, the sensor 301 is electrically connected to the position adjustment assembly 200, the shading sheet 302 is arranged on the stripping knife assembly 100 so that it can follow the horizontal movement of the stripping knife assembly 100, the sensor 301 corresponds to the midpoint position of the moving path of the shading sheet 302, and is used to sense the shading sheet 302.

[0037] The motor 210 fixed on the mounting frame 230 drives the bidirectional screw rod 220 to rotate, so that the stripping knife assembly 100 matched with the bidirectional screw rod 220 slides horizontally on the bidirectional screw rod 220, so as to achieve the position of the stripping knife assembly 100 on the bidirectional screw rod 220 controlled by the motor 210. The bidirectional screw rod 220 drives the stripping knife assembly 100 to move, so that the moving distance can be accurate and convenient to control. At the same time, the shading sheet 302 is arranged on the stripping knife assembly 100, and the shading sheet 302 moves with the movement of the stripping knife assembly 100. The sensor 301 is arranged on the mounting frame 230, and the sensor 301 is electrically connected to the position adjustment assembly 200. The sensor 301 corresponds to the midpoint position of the moving path of the shading sheet 302. When the sensor 301 senses the shading sheet 302, it means that the stripping knife assembly 100 is at the midpoint position of the bidirectional screw rod 220.

[0038] When put into use, a number of equally spaced positioning holes are symmetrically opened at both ends of the material strip, and the positioning holes are opened along the length direction of the material strip, and a number of rows of products are arranged at equal intervals between the two rows of positioning holes. If the positioning holes on one side are closer to the products on the same side, then the positioning holes on the other side are farther away from the products on the same side. Select one of the positioning holes on one side, and measure the distance between the product adjacent to the positioning hole and the center of the positioning hole. If the distance is within the tolerance range, it means that the center of the overall layout of the product is on the center of the material strip or the offset is small, then adjust the stripping knife assembly 100 to the midpoint position of the sliding on the bidirectional screw 220, so that the center of the stripping knife assembly 100 is aligned with the center of the material strip. If the distance is not within the tolerance range, it means that the overall layout of the product is offset from the center of the material strip by a large amount. Therefore, the horizontal position of the stripping knife assembly 100 needs to be appropriately adjusted so that the center of the stripping knife assembly 100 is aligned with the center of the overall layout of the product to ensure that the stripping knife assembly 100 can strip all the products on the material strip, so as to avoid the position offset of some products, which will cause the stripping knife assembly 100 to be unable to align, resulting in the stripping knife assembly 100 being unable to strip the offset products.

[0039] refer to Figure 1 and Figure 2 According to the die-cutting and stripping device of some embodiments of the present invention, the stripping knife assembly 100 includes a stripping knife body 110 and a sliding member 130 , the stripping knife body 110 and the sliding member 130 are detachably connected, and the bidirectional screw rod 220 passes through the sliding member 130 .

[0040] Specifically, a threaded hole is provided in the middle of the sliding member 130, the threaded hole penetrates the sliding member 130, the bidirectional screw rod 220 passes through the sliding member 130 through the threaded hole, and the sliding member 130 and the stripping knife body 110 can be detachably connected by means of thread connection, pin connection, etc. If the stripping knife body 110 needs to be replaced, the stripping knife body 110 can be removed from the sliding member 130 when the equipment is stopped, so as to facilitate the rapid disassembly and assembly of the stripping knife body 110.

[0041] Reference pictures, Figure 4 and Figure 7 According to the die-cutting and stripping device of some embodiments of the present invention, the stripping knife assembly 100 also includes a mounting block 120, which is arranged between the stripping knife body 110 and the sliding member 130, and the mounting block 120 is detachably connected to the stripping knife body 110, and the mounting block 120 is detachably connected to the sliding member 130.

[0042] It is understandable that the sliding member 130 and the mounting block 120 can be detachably connected by means of threaded connection, pin connection, etc. If the stripping knife body 110 of different specifications needs to be adapted to different mounting blocks 120, the mounting block 120 and the stripping knife body 110 can be removed together, which is conducive to meeting the needs of the staff during use, and flexibly choosing to replace only the stripping knife body 110 or the mounting block 120 and the stripping knife body 110 together. At the same time, since the sliding member 130 needs to slide back and forth on the bidirectional lead screw, by adding the mounting block 120, the stripping knife body 110 is prevented from being directly mounted on the sliding member 130, and the material used for mounting the stripping knife body 110 can be avoided to the greatest extent to affect the smoothness of the sliding member 130 during use. The mounting block 120 provides a mounting position for the stripping knife body 110, making the stripping knife body 110 more convenient to install.

[0043] According to the die-cutting and stripping device of some embodiments of the present invention, a sliding groove 231 is provided on the mounting frame 230 , and the sliding member 130 is slidably matched with the sliding groove 231 .

[0044] It should be understood that the bidirectional lead screw 220 passes through the sliding member 130 through the threaded hole, and the sliding member 130 slides in cooperation with the sliding groove 231. The sliding member 130 slides horizontally in the sliding groove 231 driven by the bidirectional lead screw, which can make the sliding member 130 slide more smoothly and less prone to deviation.

[0045] refer to Figure 3 , Figure 6 and Figure 7 According to the die-cutting and stripping device of some embodiments of the present invention, stabilizing plates 132 are provided at both ends of the sliding member 130, and the stabilizing plates 132 are slidably matched with the mounting frame 230. When the sliding member 130 slides in the sliding groove 231, the stabilizing plates 132 provided at both ends of the sliding member 130 fit the mounting frames 230 on both outer sides of the top of the sliding groove 231, which has a moderate limiting effect on the sliding of the sliding member 130, so that the sliding member 130 only moves horizontally during the sliding process, and will not rotate or deviate.

[0046] It can be understood that the bottom end of the stabilizing plate 132 is in contact with the top end of the mounting frame 230. When the sliding member 130 slides, the bottom end of the stabilizing plate 132 fits with the top end of the mounting frame 230, generating dynamic friction during sliding, making the sliding more stable.

[0047] refer to Figure 6 and Figure 7 According to the die-cutting and stripping device of some embodiments of the utility model, the two upper opposite groove walls of the sliding groove 231 are provided with a stabilizing groove 232, and arc blocks 133 are provided at both ends of the sliding member 130, and the arc blocks 133 are slidably matched with the stabilizing groove 232. The stabilizing groove 232 is an arc-shaped structure, and when the sliding member 130 slides in the sliding groove 231, the arc blocks 133 at both ends of the sliding member 130 are slidably matched with the stabilizing groove 232, further increasing the stability of the sliding member 130 during the sliding process.

[0048] refer to Figure 4 and Figure 5According to the die-cutting and stripping device of some embodiments of the utility model, there are at least three sensors 301, and the three sensors 301 correspond to the two end positions and the midpoint position of the moving path of the light shielding sheet 302 respectively. The sensor 301 can be a displacement sensor 301 or a photoelectric sensor 301. In this embodiment, the photoelectric sensor 301 is used to cooperate with the light shielding sheet 302. Specifically, the light shielding sheet 302 can be threaded or plugged with the sliding member 130 or the mounting block 120, or can be directly connected to the stripping knife body 110. The sensor 301 is threaded or plugged with the mounting frame 230, and the light shielding sheet 302 and the sensor 301 cooperate with each other. When the sensor 301 located in the middle senses the light shielding sheet 302, it means that the sliding member 130 is at the midpoint position of the sliding on the bidirectional screw rod 220, corresponding to the center position of the material strip. When the sensors 301 located at both ends sense the light shielding sheet 302, it means that the sliding member 130 is at the two end positions of the sliding path on the bidirectional screw rod 220. The sensor 301 is electrically connected to the motor 210 . When the sensor 301 senses the shading sheets 302 at both ends, it sends a signal to the motor 210 to stop the motor 210 from driving and the sliding member 130 from moving, thereby preventing the stripping knife body 110 from hitting the mounting frame 230 .

[0049] When adjusting the position of the sliding member 130 and the stripping knife body, the staff can first slide the sliding member 130 to the midpoint position, and then accurately adjust the position of the sliding member 130 and the stripping knife body to both ends based on the midpoint position, which facilitates the staff's operation and increases the sliding accuracy of the sliding member 130.

[0050] refer to Figure 4 According to some embodiments of the present invention, the die-cutting and stripping device further includes a swing assembly, which is connected to the mounting frame 230 and is used to swing the mounting frame 230. The swing assembly includes a base 140 and an adjustment guide rod 150, two bases 140 are arranged on both sides of the mounting frame 230, and the bases 140 and the mounting frame 230 are detachably connected, and the adjustment guide rod 150 is fixedly connected between the bases 140, and the adjustment guide rod 150 passes through the two bases 140.

[0051] It should be understood that the pin hole machine device is rotatably connected to both ends of the adjusting guide rod 150, and a fastening screw is passed through the device and the adjusting guide rod 150 to lock the device and the adjusting guide rod 150 so that the two cannot rotate relative to each other. After the screw is unscrewed, the adjusting guide rod 150 can rotate relative to the locking device to drive the stripping knife body 110 to rotate, thereby facilitating the unloading of the material belt and the replacement of the stripping knife body 110.

[0052] The pin hole machine according to the second embodiment of the utility model includes the die-cutting and stripping device according to the first embodiment.

[0053] The pin hole machine according to the embodiment of the utility model has at least the following beneficial effects: including all the beneficial effects of the die-cutting and stripping device of the first aspect embodiment, which will not be repeated here.
