Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a clamping mechanism. Background Art

[0002] The process of bottle filling and packaging involves the bottle capping process.

[0003] In the prior art, traditional screw-on capping devices are generally controlled by a cam to move up and down, wherein the clamping head in the bottle clamp adopts a semicircular design, with latching teeth arranged above the clamping head. The latching teeth clamp the bottle mouth up and down, and a baffle is provided on the side of the bottle. During the screw-on capping process, this screw-on capping device is prone to the situation where the latching teeth cannot clamp the bottle mouth tightly due to the difficulty in controlling the distance of up and down movement, which leads to the generation of wire drawing at the bottle mouth during screw-on capping. Moreover, this clamping head is not suitable for bottles with hollow threads at the bottle mouth, resulting in a narrow range of application. In addition, it is necessary to replace the appropriate baffle according to the different diameters of bottles, which affects the product qualification rate for aseptic filling. In general, the bottle clamps of existing screw-on capping devices are not suitable for bottles made of soft materials, while bottles made of hard materials are prone to wire drawing.

[0048] The utility model discloses a clamping mechanism, which clamps the bottle mouth from the side of the bottle through a cam driving component 1 and a first clamping member assembly 2, without the need for an additional auxiliary baffle. It has the advantage of firm clamping and is adaptable to bottles of different hardness, and can solve the problems existing in the prior art.

[0049] The following is a clear and detailed description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Figures 1 to 5 , the clamping mechanism provided by the present utility model comprises: a cam driving component 1 and a first clamping component assembly 2;

[0050] The first clamping member assembly 2 includes a first clamping member 21, a second clamping member 22, a roller 25 and an adjustment component 26, wherein the adjustment component 26 is used to adjust the clamping force of the first clamping member 21 and the second clamping member 22 on the bottle;

[0051] The cam driving component 1 controls the opening and closing of the first clamping member 21 and the second clamping member 22 via the roller 25 , thereby clamping or releasing the bottle.

[0052] In the present invention, the cam drive component 1 controls the opening of the first clamping member 21 and the second clamping member 22 via the roller 25, and the bottle 001 is brought into the clamping position. The cam drive component 1 then controls the closing of the first clamping member 21 and the second clamping member 22 via the roller 25. The first clamping member 21 and the second clamping member 22 clamp the bottle mouth, thereby clamping the bottle. It should be noted that the first clamping member 21 and the second clamping member 22 of the present invention can clamp the bottle from the side of the bottle mouth, rather than the upper and lower clamping method used in the prior art, which is not limited here. The clamping force of the first clamping member 21 and the second clamping member 22 on the bottle can be adjusted by the adjustment component 26, thereby accommodating bottles of different hardnesses.

[0053] Preferably,

[0054] The first clamping member assembly 2 further includes a driven shaft 23 for driving the first clamping member 21 and a driving shaft 24 for driving the second clamping member 22;

[0055] The roller 25 is mounted on the driving shaft 24 through the adjustment assembly 26;

[0056] The cam driving component 1 cooperates with the roller 25 , and the driven shaft 23 and the driving shaft 24 are driven by gears.

[0057] It should be noted that the driven shaft 23 and the driving shaft 24 are driven by a gear transmission, and the cam driving component 1 controls the rotation of the driving shaft 24 by controlling the position of the roller 25. The rotation of the driving shaft 24 simultaneously drives the rotation of the driven shaft 23, thereby controlling the relative distance between the clamping positions of the first clamping member 21 and the second clamping member 22. When the first clamping member 21 is provided with a first latching tooth 211 and the second clamping member 22 is provided with a second latching tooth 221, the cam driving component 1 controls the relative distance between the first latching tooth 211 and the second latching tooth 221 by controlling the roller 25.

[0058] Preferably,

[0059] The adjustment assembly 26 includes an adjustment member 264, a first fixing seat 261, a rolling mounting seat 262 and a second fixing seat 263 arranged in order from top to bottom;

[0060] The first fixing seat 261 and the second fixing seat 263 are fixedly mounted on the driving shaft 24 , and the rolling mounting seat 262 is rotatably mounted on the driving shaft 24 ;

[0061] The adjusting member 264 is movably connected to the first fixing seat 261 and the second fixing seat 263 , and is fixedly connected to the rolling mounting seat 262 ;

[0062] A first elastic member 265 is further provided between the adjusting member 264 and the first fixing seat 261 , and between the adjusting member 264 and the second fixing seat 263 . The adjusting member 264 is used to adjust the tightness of the first elastic member 265 .

[0063] It must be pointed out that the addition of the adjustment assembly 26 can adjust the position of the roller 25 on the driving shaft 24, that is, it can adjust the relative distance between the clamping positions of the first clamping member 21 and the second clamping member 22 when clamping the bottle. In short, it can adjust the clamping force when clamping the bottle. Therefore, the clamping mechanism of the present invention can be applied to bottles of different hardness and has a wider range of applications.

[0064] Preferably,

[0065] The adjusting member 264 is composed of a connecting plate 2641 and an adjusting bolt 2642 , wherein the two ends of the connecting plate 2641 are movably connected to the first fixing seat 261 and the second fixing seat 263 respectively, and the adjusting bolt 2642 fixes the rolling mounting seat 262 on the connecting plate 2641 through a hole opened in the middle of the connecting plate 2641 .

[0066] Specifically, due to the action of the first elastic member 265 and the fact that the first and second fixing seats 261 and 263 are fixed to the driving shaft 24, the connecting plate 2641 is always away from the first fixing seat 261. By adjusting the tightness of the first elastic member 265, the relative position of the connecting plate 2641 and the first fixing seat 261, that is, the relative position of the rolling mounting seat 262 and the first fixing seat 261, can be adjusted. When the elastic force of the first elastic member 265 is relatively high, the clamping mechanism exerts a greater force on the bottle mouth; otherwise, it exerts a smaller force, thereby accommodating bottles of varying hardness. The first elastic member 265 may be a spring. Furthermore, the first and second fixing seats 261 and 263 may be fixedly mounted to the driving shaft 24 via a combination of a keyway and a latch. An elastic member slot may be provided on one side of the connecting plate 2641 to accommodate one end of the first elastic member 265.

[0067] Preferably,

[0068] The first clamping member 21 and the abutting assembly 27 are respectively provided at both ends of the driven shaft 23;

[0071] One end of the second elastic member 272 is connected to the connecting seat 271 , and the other end is fixed on the clamping mechanism.

[0072] In the present invention, the abutting assembly 27 keeps the roller 25 in close contact with the cam of the cam driving component 1, thereby preventing the cam driving component 1 from being unable to control the first clamping component assembly 2. The second elastic member 272 may be a spring.

[0073] Preferably,

[0074] The driven shaft 23 is provided with a first clamping member 21, a driven gear 28 and a connecting seat 271 in order from top to bottom;

The first latching tooth 211 , the second latching tooth 221 and the third latching tooth 31 are used to clamp the bottle.

[0079] It should be noted that the clamping mechanism of the present invention can adopt a method of clamping by the first clamping member 21, the second clamping member 22 and the third clamping member 3. The clamping positions of the three clamping members can be distributed in a triangular shape, so that the bottle can be clamped from three positions, which has the advantage of more stable clamping.

[0080] Preferably,

[0081] The first clamping member 21 includes a first clamping seat 212 and a first clamping head 213 , wherein the first clamping head 213 is provided with a first latching tooth 211 and is mounted on the first clamping seat 212 ;

[0082] The second clamping member 22 includes a second clamping seat 222 and a second clamping head 223 , wherein the second clamping head 223 is provided with a second latching tooth 221 and is mounted on the second clamping seat 222 ;

[0084] It should be noted that the positions of the above-mentioned third clamping head 33 and the third clamping seat 32 are adjustable. Specifically, a long slot hole can be provided on the third clamping head 33. By adjusting the position of the bolt in the long slot hole to install it on the third clamping seat 32, the position of the third clamping head 33 and the third clamping seat 32 can be adjusted.

[0085] Preferably,

[0086] When the clamping mechanism clamps the bottle, the first clamping teeth 211, the third clamping teeth 31 and the second clamping teeth 221 are sequentially arranged on the circle where the clamping position of the bottle is located.

[0091] It should be noted that the cam driving component 1 is externally connected to a rotational power, such as a combination of a servo motor and a gearbox, which is not limited here; the first clamping component assembly 2 can be installed on the first base 4 and the second base 5 through structures such as bearings and sleeves. Specifically, the upper part of the first clamping component assembly 2 can be rotatably mounted on the first base 4 through a sleeve, and the lower part thereof is mounted on the second base 5 through a bearing; the third clamping component 3 can be fixedly mounted on the first base 4; when a close-fitting component 27 is provided on the driven shaft 23, one end of the second elastic component 272 can be fixed on a fixed connecting rod provided on the second base 5.
