[0028] Example 1
[0029] Reference Figure 1-3 This is the first embodiment of the present invention, providing a packaging device 1 for fruit packaging using a plastic wrap 103. The packaging device 1 includes a support frame 101, a mounting shaft 102, a plastic wrap 103, and a cutting blade 104. Both ends of the mounting shaft 102 are slidably connected to the inner wall of the support frame 101. The plastic wrap 103 is sleeved on the mounting shaft 102, and the cutting blade 104 is located on the front side of the plastic wrap 103.
[0030] The step-cutting structure 2 includes a main board 201. The two sides of the main board 201 are fixedly connected to the front side of the top of the two sides of the inner wall of the support frame 101. The top of the main board 201 is provided with a mounting plate 202. The cutting blade 104 is located at the bottom of the mounting plate 202. The two sides of the top of the main board 201 are provided with sliding grooves 203. The inner wall of the sliding grooves 203 is slidably connected with a straight rod 204. The top of the straight rod 204 is fixedly connected to the two sides of the bottom of the mounting plate 202. The bottom of the main board 201 is provided with a pedal 205. The two sides of the top of the pedal 205 are fixedly connected to the bottom of the straight rod 204.
[0031] Suspension component 3 is fixedly installed on the surface of straight rod 204;
[0032] The buffer mechanism 4 is located on the top of the mounting plate 202. The suspension assembly 3 includes a fixing ring 301. The inner wall of the fixing ring 301 is fixedly connected to the surface of the straight rod 204. A tension spring 302 is fixedly connected to the top of the fixing ring 301. The other end of the tension spring 302 is fixedly connected to the bottom of the main plate 201. A linear bearing 8 is fixedly connected to the inner wall of the slide groove 203. The surface of the straight rod 204 is slidably connected to the inner wall of the linear bearing 8.
[0033] Specifically, when the user needs to cut the plastic wrap 103, they can trigger the stepping on the cutting structure 2 with their foot, causing the suspended component 3 to move and the cutting blade 104 to descend. This allows the user to hold the fruit with both hands and operate the cutting blade 104 to cut the plastic wrap 103 without using their hands.
[0034] Furthermore, the user presses the pedal 205 with their foot. The pedal 205 drives the straight rod 204 to slide along the linear bearing 8 in the groove 203, causing the straight rod 204 to move the mounting plate 202 downward. This causes the fixing ring 301 to move downward with the straight rod 204, stretching the tension spring 302 and storing elastic potential energy so that the cutting blade 104 can be reset and suspended in the air. This allows the cutting blade 104 at the bottom of the mounting plate 202 to contact and cut the plastic wrap 103. This allows the user to hold the fruit with both hands and operate the cutting blade 104 to cut the plastic wrap 103 without using their hands, thus improving the ease of operation.
[0035] Example 2
[0036] In the second embodiment of this utility model, the buffer mechanism 4 includes a limiting groove 401. The groove is opened on the top of the mounting plate 202. A limiting rod 402 is slidably connected to the inner wall of the limiting groove 401. The bottom of the limiting rod 402 is fixedly connected to the top of the cutting blade 104. A spring 403 is sleeved on the surface of the limiting rod 402. One end of the spring 403 is fixedly connected to the top of the cutting blade 104, and the other end of the spring 403 is fixedly connected to the bottom of the mounting plate 202.
[0037] Specifically, the buffer mechanism 4 can effectively buffer the impact force when the cutting blade 104 descends, avoid the blade edge from being severely worn due to excessive cutting force, thereby extending the service life of the cutting blade 104. Furthermore, the anti-detachment block 5 is used to prevent the buffer mechanism 4 from falling apart.
[0038] Furthermore, as the mounting plate 202 descends, allowing the cutting blade 104 to contact the cling film 103, the limiting rod 402 slides within the limiting groove 401 as the mounting plate 202 continues to descend, causing the spring 403 to be stably compressed. The elastic deformation of the spring 403 absorbs part of the impact force, reducing the impact force between the cutting blade 104 and the main board 201, thereby preventing the cutting blade 104 from directly impacting the main board 201 and causing severe wear on the blade. During this process, when the limiting rod 402 slides within the limiting groove 401, the anti-detachment block 5 prevents the limiting rod 402 from detaching from the limiting groove 401 due to the rebound force of the spring 403.
[0039] Example 3
[0040] In the third embodiment of this utility model, a slanted barb 6 is fixedly connected to the rear side of the top of the motherboard 201. Several slanted barbs 6 are provided and are distributed at equal intervals. A pressure plate 7 is fixedly connected to the back of the cutting blade 104.
[0041] Specifically, by using the oblique stab 6 and the pressure plate 7, after the plastic wrap 103 is cut, the cut end of the plastic wrap 103 is still located behind the cutting blade 104, so that the user can quickly access the plastic wrap 103 afterwards.
[0042] Furthermore, when the cutting blade 104 moves down to cut the plastic wrap 103, the pressure plate 7 and the cutting blade 104 simultaneously come into contact with the plastic wrap 103 and press it down on the oblique 6. Then the plastic wrap 103 is hooked by the oblique 6, which makes it easy for the user to quickly pull the plastic wrap 103 to wrap the fruit.
[0043] Working principle:
[0044] When the user needs to wrap the fruit with plastic wrap 103, first, put the plastic wrap 103 onto the mounting shaft 102, then install the mounting shaft 102 onto the support frame 101. Next, pass one end of the plastic wrap 103 between the cutting blade 104 and the main board 201. Then, the user can rotate the fruit with both hands, pulling the plastic wrap 103 to wrap around the fruit. When the fruit is wrapped, the user presses the pedal 205 with their foot. The pedal 205 drives the straight rod 204 to slide along the linear bearing 8 in the groove 203, causing the straight rod 204 to move the mounting plate 202 downwards. This causes the fixing ring 301 to move downwards with the straight rod 204, stretching the tension spring 302 and storing elastic potential energy so that the cutting blade 104 can return to its suspended position. At this point, the cutting blade 104 at the bottom of the mounting plate 202 contacts and cuts the plastic wrap 103. During this process, when the cutting blade 104 contacts the plastic wrap 103, as the mounting plate 202 continues to descend, the limiting rod 402 slides within the limiting groove 401, causing the spring 403 to be stably compressed. The elastic deformation of the spring 403 absorbs part of the impact force, reducing the impact force between the cutting blade 104 and the main board 201. This prevents the cutting blade 104 from directly impacting the main board 201 and causing severe wear on the blade. Simultaneously, the pressure plate 7 and the cutting blade 104 contact the plastic wrap 103 and press it against the oblique 6. The plastic wrap 103 is then hooked by the oblique 6, allowing the user to quickly pull it back. This allows the user to hold the fruit with both hands and operate the cutting blade 104 to cut the plastic wrap 103 without using their hands, thus providing the advantage of convenient cutting.
[0045] In summary, the fruit packaging device 1 with plastic wrap 103, by setting up a foot-pressing and cutting structure 2, allows users to operate the cutting blade 104 by pressing down on the plastic wrap 103 after the fruit is packaged. This solves the problem that users usually use both hands to rotate the fruit and pull the plastic wrap roller to wrap it. However, some fruits require both hands to hold after wrapping, making it inconvenient for users to operate the cutting device without freeing their hands, thus causing inconvenience in the cutting operation.
