Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a cutter assembly and a vacuum sealer. Background Art

[0002] The vacuum sealer uses a vacuum pumping component to vacuum the vacuum packaging bag, and then uses a heat sealing component to heat seal the bag opening of the vacuum packaging bag to prevent the food in the vacuum packaging bag from oxidizing or deteriorating due to contact with air. It can effectively inhibit the growth of various bacteria and molds, thereby extending the shelf life.

[0003] Roll-type vacuum packaging bags are roll-shaped bags with closed sides. When using, you need to cut off a section of the bag first, and then use the heat sealing component of the vacuum sealer to heat seal one or both ends of the bag to form a vacuum packaging bag. To facilitate users to cut the bag, the vacuum sealer is generally equipped with a slidable cutter component on the cover.

[0004] However, the cutter assembly of the existing vacuum sealer usually does not have a height adjustment function, so it cannot ensure that the cutter assembly can align with the bag body for cutting, which easily leads to uneven cutting or uneven bag opening, which not only affects the cutting effect but also reduces the user experience. Summary of the invention

DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0025] like Figures 1 to 5 As shown, the utility model provides a vacuum sealer, including a machine body 1, a machine cover 2 and a cutter assembly 3; the machine cover 2 is provided with a cutter groove 21, and the machine body 1 is provided with a limit groove 11 at a corresponding position of the cutter groove 21; the cutter assembly 3 includes a sliding knife seat 31, a lifting knife holder 32, an elastic reset member 33, a cutting blade 34 and a guide column 35; the lifting knife holder 32 is arranged at the bottom of the sliding knife seat 31 so as to be able to be lifted and lowered by the elastic reset member 33, a cutting blade 34 is arranged on the side wall of the lifting knife holder 32, and a guide column 35 is arranged at the bottom of the lifting knife holder 32. The cutter assembly 3 is slidably installed in the cutter groove 21, and when the machine cover 2 is closed, the guide column 35 and the limit groove 11 abut against each other, thereby guiding the lifting knife holder 32 to achieve adaptive height adjustment.

[0026] like Figures 1 to 5 As shown, during the cutting operation, first open the cover 2, place the vacuum fresh-keeping bag on the body 1, so that the cutting position is aligned with the limiting groove 11; then close the cover 2, and drive the entire cutter assembly 3 to slide in the cutter groove 21 by pushing the sliding knife seat 31, thereby completing the cutting operation of the vacuum fresh-keeping bag through the cutting blade 34. Since an elastic reset member 33 is provided between the lifting knife holder 32 and the sliding knife holder 31, the guide column 35 can always maintain contact with the limiting groove 11 under the action of elastic force, thereby driving the lifting knife holder 32 to automatically rise and fall, ensuring that the cutting blade 34 cuts accurately and smoothly. It can be seen that the cutting blade assembly 3 in the utility model has a height adjustment function, and can adaptively adjust the height of the cutting blade 34 according to actual needs, thereby ensuring that the cutting blade 34 is aligned with the vacuum fresh-keeping bag for cutting, effectively improving the cutting effect.

[0027] like Figures 2 to 5As shown, the cutter assembly 3 also includes a housing 36 disposed at the bottom of the sliding knife seat 31, the housing 36 covers the outside of the lifting knife holder 32, and the housing 36 is provided with limiting hooks 361 on both sides of the interior; the lifting knife holder 32 is provided with limiting protrusions 323 that cooperate with the limiting hooks 361 on both sides of the exterior. The lifting height of the lifting knife holder 32 can be effectively limited by the mutual cooperation of the limiting hooks 361 and the limiting protrusions 323, and the fatigue failure of the elastic reset member 33 can be prevented, and the service life of the elastic reset member 33 can be effectively extended. As a specific assembly method: a slot 362 and a mounting hole 363 are provided on the top of the housing 36; the sliding knife holder 31 includes a sliding push button 311 and a claw 312 and a connecting column 313 disposed at the bottom of the sliding push button 311, the claw 312 is clamped in the slot 362, the connecting column 313 is inserted in the mounting hole 363, and is connected to the lifting knife holder 32 through the elastic reset member 33. After being assembled with the machine cover 2 , the sliding push button 311 is clamped on the edge of the cutting groove 21 , and the shell 36 is inserted into the cutting groove 21 , thereby effectively protecting the lifting knife holder 32 and ensuring that the entire cutting knife assembly 3 slides steadily and smoothly in the cutting groove 21 .

[0028] like Figures 2 to 5 As shown, the lifting knife holder 32 includes a connecting seat 321 and a fixed knife holder 322; the connecting seat 321 is connected to the sliding knife holder 31 through an elastic reset member 33, and a mounting cavity is provided at the bottom of the connecting seat 321; the fixed knife holder 322 is detachably arranged in the mounting cavity, and the fixed knife holder 322 is provided with a cutting blade 34 and a guide column 35. Specifically, the fixed knife holder 322 and the guide column 35 are an integrally formed structure, and both sides of the fixed knife holder 322 and the guide column 35 are provided with mounting grooves for installing the cutting blade 34. Since the lifting knife holder 32 is a detachable structure, when the cutting blade 34 needs to be replaced, the fixed knife holder 322 can be removed from the bottom of the connecting seat 321 for replacement, and the operation is simple and convenient. Guard plates 324 for shielding the cutting blade 34 are provided on the front and rear sides of the bottom of the connecting seat 321, thereby preventing people from accidental cuts and avoiding unnecessary wear of the cutting blade 34. In addition, when the machine cover 2 is closed, the bottom of the guard plate 324 abuts against the edges on both sides of the limiting groove 11, so that it can cooperate with the guide column 35 to play a double limiting role, thereby guiding the lifting tool holder 32 to achieve more precise height adaptive adjustment.

[0029] like Figures 3 to 5 As shown, as a preferred solution: the guide post 35 is a shuttle-shaped structure, which is small at both ends and large in the middle, which helps to improve the guiding and limiting function of the guide post 35, prevents the transition between the guide post 35 and the vacuum fresh-keeping bag from being smoother, and prevents the vacuum fresh-keeping bag from being pushed by the guide post 35 to wrinkle. Based on this, the cutting blades 34 on both sides of the lifting knife frame 32 are parallelogram structures, and their hypotenuses form an acute angle with the hypotenuses at the ends of the guide post 35, so that the cutting blades 34 can cut the vacuum fresh-keeping bag more accurately.

[0030] like Figure 4 and Figure 5 As shown, as a preferred solution: the elastic reset member 33 is a compression spring.

[0031] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
