[0018] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0019] Figure 1 This is a schematic diagram of a refrigerator door sealing strip trimming device according to one embodiment of the present invention. Figure 2 It is based on Figure 1 Enlarged diagram of region A in the middle. Figure 3 This is a bottom schematic diagram of a refrigerator door sealing strip trimming device according to one embodiment of the present invention. Figure 1 , Figure 2 as well as Figure 3 The trimming device may include a trimming seat 4, trimming shears 15, and a drive assembly 3. Specifically, the trimming seat 4 may include a rubber strip groove 14.

[0020] A trimming seat 4 is installed on the door seal strip conveyor line. The trimming seat 4 has a strip groove 14. The trimming scissors 15 are movably inserted through the trimming seat 4 and the strip groove 14. The drive assembly 3 is located at the end of the trimming seat 4 away from the door seal strip. The output end of the drive assembly 3 is connected to the trimming scissors 15 and is used to drive the trimming scissors 15 to move and trim the sealing part of the door seal strip inside the strip groove 14.

[0021] When it is necessary to cut the protruding sharp corners of the sealing part of the door seal strip, the trimming seat 4 is first installed on the door seal strip conveyor line. As the door seal strip after the corner is cut is conveyed on the door seal strip conveyor line, it gradually enters the inside of the strip groove 14 of the trimming seat 4. After the door seal strip reaches the corresponding cutting position, the drive assembly 3 is activated. The drive assembly 3 drives the trimming shears 15 to move in the direction towards the inside of the strip groove 14, so as to cooperate with the trimming seat 4 to trim the protruding sharp corners of the sealing part of the door seal strip. After the cutting is completed, the door seal strip continues to be conveyed to the next process for diagonal welding of the door seal strip.

[0022] Traditionally, the sharp corners of the sealing strip on the door seal of a side-by-side refrigerator are trimmed manually, a process that is inefficient and consumes significant manpower and resources. In this embodiment of the invention, a drive assembly 3 drives the trimmer 15 to move along the seal groove 14, effectively trimming the sharp corners of the sealing strip. This improves the trimming efficiency, saves manpower and resources, and ensures the aesthetic appearance of the sealing strip.

[0023] In this embodiment of the present invention, such as Figure 2 As shown, the sealing strip groove 14 may include an airbag groove 12 and a sealing groove 13. The airbag groove 12 and the sealing groove 13 correspond to the airbag part and the sealing part of the door seal strip, respectively. The trimmer 15 is located inside the sealing groove 13 to reliably and stably trim the sharp corner of the sealing part of the door seal strip.

[0024] In this embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the trimming device may also include a fixing base 5 and a connecting plate 6.

[0025] The fixed base 5 is located at the bottom of the trimming base 4, one end of the connecting plate 6 is connected to the end of the fixed base 5, and the drive assembly 3 is located at the end of the connecting plate 6 away from the fixed base 5.

[0026] The fixing seat 5 supports the trimming seat 4 and facilitates its fixation on the door seal strip conveyor line. The connecting plate 6 supports the drive assembly 3 and connects the drive assembly 3 and the trimming seat 4 into a single structure, thereby facilitating overall movement and adjustment and increasing flexibility.

[0027] In this embodiment of the present invention, such as Figure 1 as well as Figure 3 As shown, the drive assembly 3 may include a cylinder 1 and a tool holder 2.

[0028] Cylinder 1 is located at the end of connecting plate 6 away from fixed seat 5, and knife holder 2 is located at the output end of cylinder 1. Trimming shears 15 are connected to knife holder 2.

[0029] When it is necessary to trim the sharp corners of the sealing part of the door seal strip within the sealing groove 13, the cylinder 1 is activated. The cylinder 1 drives the cutter holder 2 to move, which in turn moves the trimming shears 15 along the interior of the sealing groove 13 to trim the sharp corners of the sealing part. By using the seal strip groove 14 in conjunction with the trimming shears 15, the sharp corners of the sealing part of the door seal strip can be trimmed stably, reliably, and effectively.

[0030] In this embodiment of the present invention, such as Figure 1 and Figure 3As shown, the trimmer 15 is inclined. Specifically, the trimmer 15 is inclined relative to the trimmer seat 4. This ensures stable trimming of the sealing part of the door seal strip while also allowing for clearance. It also facilitates manual inspection and verification of the trimming of the sharp corners of the sealing part of the door seal strip.

[0031] In this embodiment of the present invention, such as Figure 3 As shown, the fixing may include a discharge port 16. Specifically, the fixing base 5 has a discharge port 16, and the trimming shears 15 can move through the discharge port 16. Therefore, after the trimming shears 15 trims the sharp corner of the sealing part inside the sealing groove 13, the trimmed sharp corner of the sealing part can be pushed out along the discharge port 16 to achieve stable recovery of the sharp corner of the sealing part.

[0032] In this embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the trimming device may also include a first fixing plate 8, a second fixing plate 11, and a threaded rod 10.

[0033] The first fixing plate 8 is disposed on the side wall of the fixing seat 5, and the second fixing plate 11 is fixedly disposed on the door sealing strip conveyor line. The threaded rod 10 passes through the second fixing plate 11 and is connected to the first fixing plate 8.

[0034] When it is necessary to adjust the position of the trimming seat 4 and the trimming shears 15, the trimming seat 4 can be moved on the door seal strip conveyor line by rotating the threaded rod 10. This allows for the trimming and cutting of the sharp corners of the sealing part of door seal strips of different lengths, making it more versatile.

[0035] In this embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the first fixing plate 8 may include a guide plate 9. Specifically, the bottom of the first fixing plate 8 is provided with a guide plate 9. After the trimmer 15 trims the sealing part of the door seal strip, it is discharged along the discharge port 16. The guide plate 9 can guide the trimmed sharp corners so that they can be stably recycled.

[0036] In this embodiment of the present invention, such as Figure 1 and Figure 3 As shown, a reinforcing plate 7 is provided between the fixing base 5 and the connecting plate 6 to improve the structural stability and structural strength of the fixing base 5 and the connecting plate 6.

[0037] On the other hand, this utility model also provides a trimming system for refrigerator door seal strips. Specifically, the trimming system may include a door seal strip conveyor line and a trimming device. Specifically, as... Figure 1-3As shown, the trimming device may include a trimming seat 4, trimming shears 15, and a drive assembly 3. Specifically, the trimming seat 4 may include a rubber strip groove 14.

[0038] A trimming seat 4 is installed on the door seal strip conveyor line. The trimming seat 4 has a strip groove 14. The trimming scissors 15 are movably inserted through the trimming seat 4 and the strip groove 14. The drive assembly 3 is located at the end of the trimming seat 4 away from the door seal strip. The output end of the drive assembly 3 is connected to the trimming scissors 15 and is used to drive the trimming scissors 15 to move and trim the sealing part of the door seal strip inside the strip groove 14.

[0039] When it is necessary to cut the protruding sharp corners of the sealing part of the door seal strip, the trimming seat 4 is first installed on the door seal strip conveyor line. As the door seal strip after the corner is cut is conveyed on the door seal strip conveyor line, it gradually enters the inside of the strip groove 14 of the trimming seat 4. After the door seal strip reaches the corresponding cutting position, the drive assembly 3 is activated. The drive assembly 3 drives the trimming shears 15 to move in the direction towards the inside of the strip groove 14, so as to cooperate with the trimming seat 4 to trim the protruding sharp corners of the sealing part of the door seal strip. After the cutting is completed, the door seal strip continues to be conveyed to the next process for diagonal welding of the door seal strip.

[0040] Through the above technical solution, the refrigerator door seal strip trimming device and trimming system provided by this utility model installs the trimming seat 4 on the door seal strip conveyor line. After the door seal strip is cut at the corner, it can pass through the strip groove 14 on the trimming seat 4 during the conveying process.
