Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The special blade structure for unpacking machines provided by this utility model includes an installation platform 101 and a blade body 7 set on a special blade structure body 1. The installation platform 101 is installed on the unpacking machine, and the blade body 7 is rotated. The high-speed rotating blade body 7 cuts the outer packaging of the goods to achieve the unpacking effect. The structure and principle of the special blade structure body 1 are well known in this technical field and will not be elaborated here. The top of the installation platform 101 is provided with a sliding groove 102, and a sliding block 10 and a T-shaped slider 9 are slidably connected in the sliding groove 102 through a first moving mechanism. A spring force adjustment mechanism is provided between the T-shaped slider 9 and the sliding block 10, and the spring force adjustment mechanism is used to adjust the amount of spring force on the T-shaped slider 9. The end of the T-shaped slider 9 away from the sliding block 10 passes through the side wall of the installation platform 101 and is fixedly connected to a connecting rod 8. A motor 12 is fixedly connected to the side wall of the connecting rod 8. The output end of the motor 12 is fixedly connected to an installation plate 503, and the blade body 7 is detachably connected to the end of the installation plate 503 through the installation mechanism.

[0024] The elastic adjustment mechanism includes a fixed rod 301 fixedly connected to the side wall of the sliding block 10. A first spring 302 is sleeved on the side wall of the fixed rod 301. The two ends of the first spring 302 are fixedly connected to the T-shaped slider 9 and the sliding block 10, respectively. A sliding rod 303 is fixedly connected to the side wall of the sliding block 10. A first sliding tube 304 is fixedly connected to the side wall of the T-shaped slider 9. The sliding rod 303 is inserted into the sliding tube 304. An elastic force indicator mechanism is provided between the sliding block 10 and the mounting platform 101. The elastic force indicator mechanism is used to indicate the magnitude of the elastic force on the T-shaped slider 9. During unpacking, it can reduce the wear and collision between the blade body 7 and the material, improve the unpacking effect and service life of the blade body 7. At the same time, when the hardness of the outer packaging is high, the force between the blade body 7 and the outer packaging is greater, ensuring the unpacking effect. In addition, it can conveniently and quickly install and replace the blade body 7, improving the unpacking efficiency.

[0025] The first moving mechanism includes a threaded hole 203 opened on the side wall of the mounting platform 101, and a threaded rod 201 is threadedly connected to the threaded hole 203. One end of the threaded rod 201 is fixedly connected to a knob 202, and the other end of the threaded rod 201 abuts against the side wall of the sliding block 10. Rotating the knob 202 causes the threaded rod 201 to move in a spiral motion, and at the same time, drives the sliding block 10 to move closer to the T-shaped slider 9.

[0026] The mounting mechanism includes a positioning rod 505 fixedly connected to the end of the mounting plate 503. Two semi-cylinders 501 are connected to the end of the mounting plate 503 via a second moving mechanism, and a semi-circularly arranged semi-disc 502 is fixedly connected to the end of each semi-cylinder 501. The top of each semi-disc 502 has a conical surface 504. The end face of the blade body 7 has a mounting hole 701 and a positioning hole 702. When the blade body 7 needs to be installed, the mounting hole 701 and the positioning hole 702 on the blade body 7 are aligned with the positioning rod 505 and the semi-disc 502 on the mounting plate 503, respectively. Then, the blade body 7 is pushed towards the mounting plate 503. When the wall of the mounting hole 701 abuts against the conical surface 504 on the semi-disc 502, the blade body 7 is continued to be pushed. The two semicircular disks 502 move closer to each other, simultaneously driving the sliding plate 402 to move synchronously. When the wall of the mounting hole 701 is completely detached from the conical surface 504, one end face of the blade body 7 is in contact with the end face of the mounting disk 503. Under the action of the second moving mechanism, the semi-cylinder 501 and the semicircular disk 502 are pulled back to their original positions. At this time, the side wall of the semi-cylinder 501 is in contact with the wall of the mounting hole 701, and the semicircular disk 502 is in contact with the other end face of the blade body 7, restricting the outward movement of the blade body 7 and completing the blade installation. The installation is more convenient and quick. When the blade body 7 needs to be replaced, the two moving semicircular disks 502 and the semi-cylinder 501 are pushed closer to each other to remove the blade body 7 from the semi-cylinder 501. The disassembly is more convenient and quick.

[0027] The second moving mechanism includes a moving groove 401 located on the end face of the mounting plate 503. Two sliding plates 402 are slidably connected within the moving groove 401. The sidewall of each sliding plate 402 is fixedly connected to the bottom of the semi-cylinder 501. The sidewall of the moving groove 401 and the sidewall of the sliding plate 402 are provided with a reset mechanism, which is used to reset and move the sliding plate 402.

[0028] When the semi-cylinder 501 moves, it causes the sliding plate 402 to slide within the moving groove 401.

[0029] The elasticity indicator mechanism includes multiple arrayed scale blocks 601 fixedly connected to the top of the mounting platform 101. A pointer block 602 is fixedly connected to the side wall of the sliding block 10. When the sliding block 10 moves, the first spring 302 is further compressed. At the same time, the pointer block 602 is moved. The position of the pointer block 602 changes the corresponding scale block 601, which in turn represents the magnitude of the elasticity of the corresponding first spring 302. This facilitates the adjustment and control of the force between the blade body 7 and the outer packaging of the goods.

[0030] The reset mechanism includes two sets of second springs 403 fixedly connected to the side wall of the moving groove 401, and the second springs 403 are symmetrically distributed. The other end of the second spring 403 is fixedly connected to the side wall of the sliding plate 402. During installation, when the two semicircular disks 502 approach each other, they drive the sliding plate 402 to move synchronously, and the second springs 403 are stretched. When the wall of the mounting hole 701 is just completely separated from the conical surface 504, one end face of the blade body 7 is just in contact with the end face of the mounting disk 503. At the same time, under the action of the second springs 403, the semi-cylinder 501 and the semi-circular disk 502 are pulled back to their original positions. At this time, the side wall of the semi-cylinder 501 is in contact with the wall of the mounting hole 701.

[0031] Working principle: During operation, firstly, the special blade structure body 1 is installed on the unpacking machine via the mounting ring 11. Then, the blade body 7 is removed, and the mounting hole 701 and positioning hole 702 on the blade body 7 are aligned with the positioning rod 505 and the semi-circular disk 502 on the mounting plate 503, respectively. Then, the blade body 7 is pushed towards the mounting plate 503. When the wall of the mounting hole 701 abuts against the conical surface 504 on the semi-circular disk 502, the blade body 7 is continued to be pushed, and the two semi-circular disks 502 move closer to each other. The sliding plate 402 moves synchronously, and the second spring 403 is stretched. When the wall of the mounting hole 701 is completely separated from the conical surface 504, one end face of the blade body 7 is in contact with the end face of the mounting plate 503. At the same time, under the action of the second spring 403, the semi-cylinder 501 and the semi-disc 502 are pulled back to their original positions. At this time, the side wall of the semi-cylinder 501 is in contact with the wall of the mounting hole 701, and the semi-disc 502 is in contact with the other end face of the blade body 7, restricting the blade body 7 from moving outward, thus completing the blade installation.

[0032] After the blade installation is completed, the motor 12 is started, causing the mounting plate 503 to rotate the blade body 7. Then, the goods to be unpacked are moved close to the blade body 7, allowing the blade body 7 to cut and unpack the outer packaging. When the unpacked goods are made of hard material, the blade body 7 moves towards the mounting platform 101 when it comes into contact with the goods. At the same time, the connecting rod 8 drives the T-shaped slider 9 to move towards the sliding block 10 in the sliding groove 102, causing the first spring 302 to compress. When the blade body 7 separates from the goods, the blade body 7 returns to its original position under the action of the first spring 302. This reduces wear and collision between the blade body 7 and the goods when the unpacked goods are made of hard material, thus extending the service life of the blade body 7.

[0033] When cutting and unpacking goods with high hardness, the knob 202 can be rotated to make the threaded rod 201 move in a spiral motion. At the same time, the sliding block 10 is moved closer to the T-shaped slider 9. The T-shaped slider 9 abuts against the side wall of the sliding groove 102, which further compresses the first spring 302, thereby adjusting the elastic force of the first spring 302 and increasing the elastic force on the T-shaped slider 9. When the sliding block 10 moves, it drives the pointer block 602 to move. The position of the pointer block 602 changes the corresponding scale block 601, which in turn represents the magnitude of the elastic force of the first spring 302. This ensures that the force between the blade body 7 and the outer packaging of the goods is greater, thus ensuring the unpacking effect.

[0034] When the blade body 7 needs to be replaced after a long period of use, push the two semi-circular discs 502 closer to each other. When the conical surface 504 contacts the wall of the mounting hole 701, release the restriction of the semi-circular discs 502 on the blade body 7, and then remove the old blade body 7 and install the new one to complete the installation, ensuring the effect of the next unpacking.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
