Technical Field
[0001] This utility model belongs to the field of packaging bag cutting technology, specifically relating to a cutting clamp suitable for cutting blind bags of snacks. Background Technology
[0002] With changing consumption trends, cross-industry consumption scenarios are becoming increasingly common. In the leisure consumption sector, many products are beginning to combine the functions of food and entertainment. Based on the unknown nature of what is purchased and what is received, the surprise and excitement of a lottery have made trendy blind boxes and snack blind bags very popular among young people. Snack blind bags, in particular, are a type of packaging where different foods are packaged in multiple individual bags, connected by heat-sealed edges or easy-tear lines. While the individual bags on the sides are easy to tear open, tearing open the bag in the middle requires separating all the individual bags one by one, significantly reducing the enjoyment. Furthermore, because the individual bags are tightly connected, improper force when separating them can easily damage other unused bags, affecting the user experience. Utility Model Content

Detailed Implementation
[0025] The present invention will be further described below through specific embodiments.
[0026] like Figures 1 to 8 As shown, this embodiment provides a cutting clamp for cutting and sealing a blind snack bag 1, including a sealing clamp 2, a cutting mechanism 3, and a limiting mechanism 4.
[0027] The snack blind bag 1 includes multiple parallel rows of individual packaging bags 11, which are connected by heat-sealed edges or easy-tear lines. Each individual packaging bag 11 is made of opaque material and can be filled with snacks or pet food. Before opening the individual packaging bag 11, the user cannot determine whether the contents are for a human or a pet, making it full of uncertainty. Specifically, the openings of the multiple individual packaging bags 11 on the snack blind bag 1 face the same direction. Furthermore, the individual packaging bags 11 are common sealed packaging bags in the prior art, and their specific structures will not be described in detail here.
[0028] The sealing clip 2 is used to hold the opening of the snack blind bag 1. It includes an upper clamp 21 and a lower clamp 22 that can be rotatably opened and closed, and a fixing component 23 disposed between the upper clamp 21 and the lower clamp 22. Through the cooperation between the upper clamp 21, the lower clamp 22 and the fixing component 23, multiple independent packaging bags 11 are unfolded and arranged on the sealing clip 2, which facilitates cutting and storing the snack blind bags 1. Specifically, the fixing component 23 includes a first fixing hole 24 disposed on the upper clamp 21, a second fixing hole 25 disposed on the lower clamp 22 opposite to the first fixing hole 24, and a fixing bolt 26 that cooperates with the first fixing hole 24 and the second fixing hole 25 in sequence. Further, one end of the lower clamp 22 extends outward to form a rotating groove 27, and one end of the upper clamp 21 is provided with a rotating part 28 that is adapted to the rotating groove 27. The rotating groove 27 and the rotating part 28 are connected by a rotating shaft 29.
[0029] The cutting mechanism 3, mounted on the sealing clamp 2, is used to cut one of the individual packaging bags 11 of the snack blind bag 1. It includes a movable cavity 31 extending vertically through the upper clamp 21, a sliding seat 32 movably mounted within the movable cavity 31, a cutter seat 33 movably mounted on the sliding seat 32 for cutting the relative individual packaging bag 11, a return spring 34 positioned between the cutter seat 33 and the sliding seat 32, and a cutter groove 35 positioned on the top surface of the lower clamp 22 opposite to the cutter seat 33. Through the interaction of the movable cavity 31, the sliding seat 32, the cutter seat 33, the return spring 34, and the cutter groove 35, the user can open one of the individual packaging bags 11 located in the middle of the snack blind bag 1 without needing to... The blind snack bag 1 is split open to avoid damaging other individual packaging bags 11 and causing waste. At the same time, it satisfies the user's fun of opening the bag and improves the user's unpacking experience. Specifically, when the cutter seat 33 moves downward to cut the corresponding individual packaging bag 11, the lower end of the cutter seat 33 is embedded in the cutter groove 35 to cut the corresponding individual packaging bag 11. At this time, the return spring 34 is compressed and deformed. After the cutter seat 33 completes the cutting of the corresponding individual packaging bag 11, the return spring 34 provides the cutter seat 33 with an upward moving force to return to the original position. Furthermore, the cutter seat 33 includes a main body 331 that can be movably disposed in the sliding seat 32, and a part disposed on the upper end of the main body 331. The upper clamp 21 has a pressing part 332, a limiting part 333 located at the lower end of the main body 331, and a cutting part 334 located at the lower end of the limiting part 333 for cutting the individual packaging bag 11. The cutting part 334 can be embedded in the relative cutting groove 35 to cut the individual packaging bag 11. The lower end of the cutting part 334 has a cutting blade 335 for cutting the individual packaging bag 11. The return spring 34 is sleeved on the outer periphery of the main body 331, with one end connected to the pressing part 332 and the other end connected to the sliding seat 32. Furthermore, the sliding seat 32 has a moving hole 321 for the main body 331, the limiting part 333, and the cutting part 334 to move up and down. The moving hole 321 includes upper and lower sliding holes. The limiting section 322 and the moving section 323 are connected in the next step. The limiting part 333 and the cutting part 334 are disposed in the moving section 323. The diameter of the limiting section 322 is smaller than the diameter of the moving section 323, and the diameter of the limiting part 333 is larger than the diameter of the limiting section 322. When the cutter holder 33 moves downward, the limiting part 333 and the cutting part 334 at the lower end of the main body 331 move towards the cutting groove 35 in the moving section 323. When the cutter holder 33 moves upward, the limiting part 333 and the cutting part 334 in the main body 331 move away from the cutting groove 35 in the moving section 323. At this time, the limiting part 333 and the limiting section 322 come into contact and abut against each other to prevent the limiting part 333 and the cutting part 334 from disengaging from the moving hole 321.Furthermore, the sliding seat 32 includes a sliding block 324 movably disposed in the moving cavity 31 and two guide blocks 325 respectively disposed on both sides of the sliding block 324. Two outwardly extending guide grooves 311 are formed on both sides of the moving cavity 31 for the relative guide blocks 325 to be inserted into.
[0030] A limiting mechanism 4, disposed between the cutter holder 33 and the moving cavity 31, is used to restrict the movement of the cutter holder 33. It includes multiple limiting rods 41 spaced apart along the length of the upper clamp 21 and a limiting block 42 disposed at the lower end of the pressing part 332 that abuts against the corresponding limiting rod 41. Individual packaging bags 11 are disposed between adjacent limiting rods 41. Through the cooperation between the multiple limiting rods 41 and the limiting block 42, the cutter holder 33 is prevented from moving to the position of the preceding or following individual packaging bag 11 during the cutting process, thereby avoiding cutting it. The individual packaging bag 11; specifically, when the cutter head 33 moves downward to cut the relatively individual packaging bag 11, the limiting block 42 moves downward into the moving cavity 31 along with the pressing part 332. At the same time, the moving cutter head 33 moves between the two adjacent limiting rods 41 and cuts the relatively individual packaging bag 11. During the movement, the limiting block 42 can contact and abut against the two adjacent limiting rods 41 respectively. When the cutter head 33 moves upward to reset, the limiting block 42 moves upward along with the pressing part 332 and is located above the limiting rods 41, so that the cutter... The tool holder 33 can move back and forth in the moving cavity 31; further, the limiting rod 41 includes a rod body 43 movably disposed in the moving cavity 31, a knob 44 disposed at one end of the rod body 43 and connected by a thread, a first clamping block 45 disposed on the surface opposite to the knob 44 and the rod body 43, and a second clamping block 46 disposed at the other end of the rod body 43 and opposite to the first clamping block 45. A limiting cavity 312 is formed on one side of the moving cavity 31 for the multiple limiting rods 41 to move back and forth. The first clamping block 45 and the second clamping block 46 can respectively clamp the limiting cavity 312. The two outer surfaces of the rod 43 are in contact with each other to fix the rod body 43 in the limiting cavity 312. Through the cooperation between the rod body 43, the knob 44, the first clamping block 45 and the second clamping block 46, the position of the limiting rod 41 in the limiting cavity 312 can be changed, thereby adjusting the distance between two adjacent limiting rods 41 to adapt to different sizes of independent packaging bags 11 and improve the practicality of the cutting tool clamp. Furthermore, the rod body 43 is square and can be embedded in the limiting cavity 312 to restrict the rotation of the limiting rod 41 in the limiting cavity 312.
[0031] The specific working principle of this application is as follows:
[0032] In its original state, the cutter holder 33 is located above the lower clamp 22 and does not contact the corresponding independent packaging bag 11. The sliding seat 32 can drive the cutter holder 33 to move back and forth in the moving cavity 31. When cutting one of the independent packaging bags 11 in the middle position on the snack blind bag 1, first move the cutter holder 33 above the corresponding independent packaging bag 11, then press the cutter holder 33 to make the cutting part 334 move downward in the sliding seat 32, extend out of the moving hole 321 and embed into the cutter groove 35. Then move the sliding seat 32 to make the cutting blade 335 of the cutting part 334 cut the corresponding independent packaging bag 11. At the same time, the limiting block 42 on the pressing part 332 moves downward into the moving cavity 31 and is opposite to the two adjacent limiting rods 41. The cutter holder 33 slides to one of the limiting rods 41 and abuts against it. The cutter holder 33 is resisted. When the user feels the resistance, he can stop applying force to avoid accidentally opening other independent packaging bags 11 connected to it.
[0033] In summary, by utilizing the above-mentioned technical solution of this utility model, through the cooperation between the sealing clip 2 and the cutting mechanism 3 set on the sealing clip 2, any individual packaging bag 11 in the snack blind bag 1 can be selectively opened without disassembling the snack blind bag 1. This avoids damaging the individual packaging bags 11 located on both sides when opening the individual packaging bag 11 located in the middle position, while satisfying the user's enjoyment of opening the bag and improving the user's bag opening experience. In addition, through the cooperation between the rotatable upper clamp 21 and lower clamp 22 and the fixing component 23 set between the upper clamp 21 and lower clamp 22, multiple individual packaging bags 11 can be unfolded and arranged on the sealing clip 2, which is convenient for cutting and storing the snack blind bag 1. Furthermore, through the multiple limiting positions set at intervals along the length direction of the upper clamp 21, The interaction between the rod 41 and the limiting block 42 located at the lower end of the pressing part 332 that abuts against the relative limiting rod 41 prevents the cutter holder 33 from moving to the position of the previous or next independent packaging bag 11 during the cutting process, thereby avoiding cutting other independent packaging bags 11. In addition, the interaction between the rod 43 movably located in the moving cavity 31, the knob 44 located at one end of the rod 43 and connected by a thread, the first clamping block 45 located on the surface opposite the knob 44 and the rod 43, and the second clamping block 46 located at the other end of the rod 43 and opposite to the first clamping block 45, can change the position of the limiting rod 41 in the limiting cavity 312, thereby adjusting the distance between two adjacent limiting rods 41 to adapt to independent packaging bags 11 of different sizes and improve the practicality of the cutter fixture.
[0034] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
