Description

Technical Field

[0001] This utility model relates to the field of refrigerator sealing strip cutting technology, specifically a refrigerator sealing strip cutting mechanism. Background Technology

[0002] A refrigerator sealing strip is a refrigerator accessory used between the refrigerator door and the refrigerator body. It is usually a rectangular frame formed by four isosceles trapezoidal sealing strips connected end to end. It is used to maintain the refrigerator's airtightness, prevent cold air from leaking out, and ensure the cooling effect. During the production process of refrigerator sealing strips, they need to be cut to the specified size by a cutting mechanism.

[0003] For example, Chinese utility model patent CN221677296U discloses a refrigerator sealing strip cutting mechanism, which relates to the field of refrigerator sealing strip processing technology. The mechanism includes a frame with a conveyor belt rotatably connected inside. Two inclined grooves are symmetrically formed on the frame, and a sliding groove is formed at one end of each of the two inclined grooves. A first sliding plate is slidably connected within each of the two inclined grooves, and a cutting blade is provided at one end of each of the two first sliding plates. Two second sliding plates are slidably connected relative to each other within the sliding grooves, and the two second sliding plates abut against the two first sliding plates in a one-to-one correspondence. This refrigerator sealing strip cutting mechanism transports the entire sealing strip via the conveyor belt. During the relative sliding of the two second sliding plates, they abut against the corresponding first sliding plates. During this abutment, the two first sliding plates slide along the length of the two sliding grooves, causing the two cutting blades to cut the sealing strip. This allows for the cutting of three segments of the sealing strip at once: two isosceles trapezoidal sealing strips and the remaining sealing strip.

[0004] However, existing refrigerator sealing strip cutting mechanisms still have some problems during use. For example, they are not convenient for limiting and conveying refrigerator sealing strips of different sizes, not convenient for cutting multiple sections of refrigerator sealing strips at once, and have limited cutting effect and efficiency. They are also not convenient for adjusting the cutting size of the refrigerator sealing strip. Therefore, we propose a refrigerator sealing strip cutting mechanism to solve the problems mentioned above. Utility Model Content

[0027] 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.

[0028] Please see Figure 1-6 This utility model provides a technical solution: a refrigerator sealing strip cutting mechanism, including a base 1, a conveyor belt 2, a fixed plate 3, a movable plate 4, a first support rod 5, a limiting sleeve 6, a second support rod 7, a cover plate 8, a locking screw 9, a receiving plate 10, a mounting plate 11, an electric telescopic rod 12, a cutter 13, a first adjusting rod 14, a second adjusting rod 15, a scale 16, and a controller 17. The base 1 houses the flush-mounted conveyor belt 2 and the cutter 13 positioned above and behind the conveyor belt 2. An adjustable limiting structure for the refrigerator sealing strip is provided on the upper outer side of the conveyor belt 2, and this adjustable limiting structure is located on the upper side of the base 1. The positioning structure includes a fixed plate 3, a movable plate 4, a first support rod 5, a limiting sleeve 6, a second support rod 7, a cover plate 8, and a locking screw 9. The fixed plate 3 and the movable plate 4 are located on the upper rear side and the upper surface of the conveyor belt 2, respectively. The fixed plate 3 is fixedly connected to the base 1. An adjustable spacing structure is provided behind the cutter 13. The adjustable spacing structure is used to adjust the cutting size of the refrigerator sealing strip. The adjustable spacing structure includes a receiving plate 10, a mounting plate 11, an electric telescopic rod 12, a first adjusting rod 14, a second adjusting rod 15, and a scale 16. The receiving plate 10 is attached to the inner side of the left rear end and the inner side of the right rear end of the base 1.

[0029] To address the problems in existing technologies, such as the inconvenience of limiting and conveying refrigerator sealing strips of different sizes, the difficulty of cutting multiple segments of refrigerator sealing strips at once, limited cutting effect and efficiency, and the inconvenience of adjusting the cutting size of the refrigerator sealing strip by the adjustment mechanism, this embodiment adopts the following technical solution, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5First, multiple refrigerator sealing strips can be stacked and placed on the upper rear end of the conveyor belt 2, which is installed flush with the base 1. This allows the refrigerator sealing strips to adhere to the upper rear side of the conveyor belt 2 and be fixedly connected to the base 1 via the fixing plate 3. Then, the movable plate 4, nested outside the first support rod 5 and the second support rod 7, can be moved backward, so that the lower end of the movable plate 4 adheres to the front side of the refrigerator sealing strip. Next, the limiting sleeve 6, threaded onto the first support rod 5, can be rotated, causing the limiting sleeve 6 to adhere to the front of the movable plate 4, thus limiting the movable plate 4 and ensuring that the refrigerator sealing strip is positioned between the fixing plate 3 and the base 1. Inside the movable plate 4, the locking screw 9 connected to the threaded connection inside the movable plate 4 can be rotated to disconnect the contact between the locking screw 9 and the cover plate 8 below it. Then the cover plate 8 can be moved so that its rear end is in contact with the fixed plate 3 behind it, so that the cover plate 8 is located on the upper side of the refrigerator sealing strip. Finally, the locking screw 9 can be reversed to limit the cover plate 8 and the movable plate 4, thereby facilitating the limiting of refrigerator sealing strips of different sizes to be cut, so as to limit the subsequent operation of conveyor belt 2 and thus improve the cutting effect of the refrigerator sealing strip in the later stage.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 6 After limiting the refrigerator sealing strip, according to the required length of the refrigerator sealing strip, the markings on the upper rear end of the base 1 are fixed by the scale 16. The first adjusting rod 14, which is engaged with the inner rear end of the base 1, and the second adjusting rod 15, which is engaged with the inner side of the receiving plate 10, are rotated. Since the receiving plate 10 is attached to the inner sides of both the left and right ends of the base 1, and symmetrical mounting plates 11 are attached to the receiving plate 10, the first adjusting rod 14 is threaded to the inner lower end of the receiving plate 10, and the second adjusting rod is threaded to the inner side of the mounting plate 11. 15. An electric telescopic rod 12 for fixing the front cutter 13 is embedded in the inner side of the front end of the mounting plate 11. Therefore, by rotating the first adjusting rod 14, the receiving plate 10 can be moved under the contact limit of the base 1. By rotating the second adjusting rod 15, the mounting plate 11 can be moved under the contact limit of the receiving plate 10. The position of the mounting plate 11 can be adjusted to achieve the purpose of adjusting the position of the cutter 13, thereby facilitating the adjustment of the cutting size of the refrigerator sealing strip by the cutter 13.

[0031] like Figure 1 , Figure 2 and Figure 3Then, the controller 17, which is embedded in the inner side of the upper rear end of the base 1, can be used to control the operation of the conveyor belt 2, so that the conveyor belt 2 can transport the refrigerator sealing strip at its upper limit. Then, the controller 17 can control the electric telescopic rod 12, which is embedded in the inner side of the front end of the mounting plate 11, to work, so that the electric telescopic rod 12 drives the cutter 13 fixed in front of it to move forward, so that the cutter 13 cuts the refrigerator sealing strip, achieving the purpose of cutting multiple sections of refrigerator sealing strip at one time, so as to achieve high cutting efficiency. The electrical components mentioned above are all existing technologies and will not be described in detail here.
