[0023] The specific embodiments of the present application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0024] Please refer to Figure 1 and Figure 2 The present application provides a cap opener, which comprises a fixed frame 10, a movable frame 20 and a connecting rod 30. The fixed frame 10 forms an accommodating groove A inside, and the groove bottom of the accommodating groove A is provided with a first clamping opening 10a for clamping the bag opening of the packaging bag placed in the accommodating groove A. The movable frame 20 is arranged in the accommodating groove and can reciprocate along the vertical direction. The inside of the movable frame 20 forms a clamping groove B, and the groove bottom of the clamping groove B is provided with a second clamping opening. The opening direction of the second clamping opening is consistent with that of the first clamping opening 10a, and the second clamping opening is used for clamping the inner plug of the bag opening. The connecting rod 30 penetrates the top of the fixed frame 10 along the vertical direction and extends into the accommodating groove A and is connected with the movable frame 20. The connecting rod 30 is at least partially located outside the accommodating groove A and is used to drive the movable frame 20 to reciprocate along the vertical direction.

[0025] The cover opener based on the technical features has the following advantages: the accommodating groove A is formed in the fixed frame 10, the first clamping opening 10a is arranged at the groove bottom of the accommodating groove A, the movable frame 20 with the clamping groove B is arranged in the accommodating groove A, the movable frame 20 can move reciprocatingly in the vertical direction, when the inner plug of the bag opening needs to be taken out, the bag opening of the packaging bag is put into the accommodating groove A, at this time, the bag opening of the packaging bag is clamped at the first clamping opening 10a, and the inner plug is clamped at the second clamping opening, then the connecting rod 30 is used to drive the movable frame 20 to move upward in the vertical direction, so that the inner plug is pulled upward to separate from the bag opening, thereby realizing the cover opening operation, the structure is simple, the operation is convenient, the labor intensity of workers in the cover opening operation is reduced, meanwhile, the bag opening is not damaged in the cover opening process, the inner plug can still be resealed to the bag opening, and the problem that the remaining auxiliary materials are deteriorated due to the incomplete resealing is avoided.

[0026] Exemplarily, in the cover opening process, in order to avoid that the connecting frame or the movable frame 20 is damaged due to small structural strength, thereby failing to normally perform the cover opening, in the embodiment, the connecting frame and the movable frame 20 can be made of metal material, thereby ensuring that the connecting frame and the movable frame 20 have sufficient structural strength, and avoiding damage in the cover opening process. Specifically, the connecting frame and the movable frame 20 are made of aluminum alloy material.

[0027] In addition, it needs to be noted that the way that the connecting rod 30 is used to drive the movable frame 20 to move reciprocatingly in the vertical direction can adopt the following two ways, but is not limited thereto, and the specific ways are as follows:

[0028] The first way is that a power component is used to pull the connecting rod 30 to move in the vertical direction, so as to pull the movable frame 20 to move in the vertical direction, thereby pulling the inner plug upward to separate from the bag opening.

[0029] Please refer to Figure 3 The second way is that a threaded transmission is adopted, that is, a threaded hole 10b is arranged at the top of the fixed frame 10, an external thread (not shown) matched with the threaded hole 10b is arranged on the rod body of the connecting rod 30, so that the connecting rod 30 is rotated to drive the movable frame 20 to move reciprocatingly in the vertical direction, since the movable frame 20 is arranged in the accommodating groove A in the fixed frame 10, and is limited by the inner wall of the fixed frame 10 to not rotate, but only moves in the vertical direction along with the connecting rod 30.

[0030] In an embodiment, the first clamping opening 10a and the second clamping opening are both in U shape, and the projection of the second clamping opening at the groove bottom of the accommodating groove A completely falls into the first clamping opening 10a, that is, the opening width L1 of the first clamping opening 10a is greater than the opening width L2 of the second clamping opening (refer to Figure 2 ).

[0031] Exemplarily, when the packaging bag is opened, the inner plug on the bag opening is aligned with the second clamping opening, and the lower surface of the inner plug is located above the second clamping opening. At this time, the bag opening of the packaging bag is aligned with the first clamping opening 10a. By pushing the packaging bag into the accommodating groove A, the inner plug can be clamped in the second clamping opening, and the bottle opening is clamped in the first clamping opening 10a, so that the butt joint is quickly realized without the need for further adjustment, which is beneficial to improve the opening efficiency. In addition, the center of the second clamping opening overlaps the center of the first clamping opening 10a. In this way, the inner plug and the bottle opening can be clamped in the second clamping opening and the first clamping opening 10a, respectively, more quickly, the number of adjustments is reduced, and the opening efficiency is improved.

[0032] In an embodiment, an adjusting hand wheel 50 is further included, which is connected to one end of the connecting rod 30 outside the accommodating groove A for driving the connecting rod 30 to rotate. In this way, the connecting rod 30 can be driven to rotate by rotating the adjusting hand wheel 50, thereby driving the movable frame 20 to move in the vertical direction, which is convenient for the worker to operate.

[0033] In an embodiment, a connecting hole for connecting with the end of the connecting rod 30 is formed in the middle of the adjusting hand wheel 50, and a plurality of outwardly extending extensions 50a are circumferentially distributed on the outer edge of the adjusting hand wheel 50, and an arc-shaped groove C is defined between adjacent two extensions 50a. That is, the adjusting hand wheel 50 can be detachably connected with the end of the connecting rod 30 through the connecting hole, so as to be replaced later. In addition, by providing a plurality of extensions 50a on the outer edge of the adjusting hand wheel 50, and defining an arc-shaped groove C between adjacent two extensions 50a, the fingers of the worker can be fitted in the arc-shaped groove C, which can prevent slipping during the rotation of the adjusting hand wheel 50.

[0034] In an embodiment, a limiting block 40 is further included, which is located in the accommodating groove A and fixed to the groove top surface of the accommodating groove A. The part of the connecting rod 30 extending into the accommodating groove A penetrates through the limiting block 40, and the limiting block 40 is used for limiting the moving position of the movable frame 20. In this way, the distance of upward movement of the movable frame 20 can be limited by the limiting block 40, which prevents the wear caused by the collision with the top surface of the fixed frame 10.

[0035] In an embodiment, a mounting hole 20a is formed in the top surface of the movable frame 20, which is used for connecting with one end of the connecting rod 30 extending into the accommodating groove A. In this way, the detachable connection between the movable frame 20 and the connecting rod 30 can be realized, which is convenient for subsequent disassembly or replacement, and the structure is simple and convenient to disassemble and assemble.

[0036] The above merely is the preferred implementation form of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
