[0001] The utility model relates to the technical field of bottle clamps, in particular to a bottle clamp for a filling machine. Background Art

[0002] A filling machine is a mechanical device used to automatically fill liquid or semi-fluid materials. Such machines can accurately and efficiently fill products into various containers, such as bottles, cans, bags or other packaging forms. Bottle clamps for filling machines are a key component used to clamp and stabilize bottles in filling production lines, especially during the process of transferring bottles from one workstation to another.

[0003] The patent with announcement number CN220467542U discloses a bottle clamp suitable for a filling machine, including a clamp base, two symmetrically arranged clamping pieces connected to the top of the clamp base, a spring connected between the two clamping pieces, and both clamping pieces are rotatably connected to the clamp base. Although the cost is increased by arranging two clamping pieces, a threaded column and a spring on the clamp base, the stability of the product is also increased. Compared with the plastic clamp of the original structure, the risk of elastic failure of the plastic after use is reduced, the service life is increased, and rapid transmission operation is achieved to meet the rapid replacement of bottle mouths of different bottle types, improve efficiency, have a reliable connection, and run more stably. The structure is simple, the operation is convenient, and the practicability is strong.

[0004] However, the above-mentioned filling machine bottle clamp still has the following problems in actual use:

[0005] Most of the existing bottle clamps have only two long clamps, which are used to clamp the bottle from below the boss of the bottle mouth. However, after the bottle clamp clamps the filled bottle, the liquid inside the bottle has weight after the bottle is filled, which causes the bottle to shake inside the bottle clamp. Most of the existing methods are to increase the clamping force of the bottle clamp, but increasing the clamping force may scratch the bottle body, or even cause the bottle body to crack or break.

When a user clamps a bottle using two long clamps and two short clamps, the bottle can be clamped from the upper and lower sides of the bottle mouth boss at the same time, thereby increasing the overall stability and the clamped bottle is not prone to shaking.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bottle clamp for a filling machine, comprising two long clamps, the upper surfaces of the two long clamps are connected to short clamps, the upper surfaces of the two short clamps are also connected to a base, the same end of the two long clamps and the two short clamps is provided with a clamping opening, and the four clamping openings are matched and aligned, the adjacent sides of the four clamping openings are provided with anti-slip openings, the sides of the four anti-slip openings away from the four clamping openings are all provided with chamfers, the bottom surfaces of the two long clamps are also connected to a bottom plate, the end of the bottom plate away from the clamping opening is connected to an expansion component, the other end of the expansion component passes through the bottom plate, the two long clamps and the two short clamps, and is connected to the base, the ends of the two long clamps away from the clamping opening are connected to a supporting component, the end of the expansion component away from the bottom plate is connected to the two supporting components, and a reset piece is connected between the ends of the two long clamps close to the clamping opening.

[0008] Furthermore, the expansion component includes a shift block, an elliptical block and a connecting rod. The upper surface of the shift block is fixedly connected to the bottom surface of the elliptical block.

The upper surface of the elliptical block is fixedly connected to one side of the connecting rod, and the outer wall of the other end of the connecting rod is fixedly connected to the inner wall of the base.

[0009] Furthermore, the support assembly includes a connecting plate and a top block, both ends of the connecting plate are fixedly connected to the inner side of the long clamp, one end of the top block is fixedly connected to the middle of the connecting plate, and the other end of the top block is against the outer wall of the elliptical block.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 5 , a bottle clamp for a filling machine, comprising two long clamps 1, the upper surfaces of the two long clamps 1 are connected with short clamps 2, the upper surfaces of the two short clamps 2 are simultaneously connected with a base 3, the same end of the two long clamps 1 and the two short clamps 2 is simultaneously provided with a clamping opening 101, and the four clamping openings 101 are matched and aligned, the adjacent sides of the four clamping openings 101 are each provided with an anti-slip opening 102, and the four anti-slip openings 102 are each provided with a chamfer 103 on the side away from the four clamping openings 101, the bottom surfaces of the two long clamps 1 are simultaneously connected with a bottom plate 4, one end of the bottom plate 4 away from the clamping opening 101 is connected with an expansion component, the other end of the expansion component passes through the bottom plate 4, the two long clamps 1 and the two short clamps 2, and is connected to the base 3, the ends of the two long clamps 1 away from the clamping opening 101 are both connected with a supporting component, the end of the expansion component away from the bottom plate 4 is connected to two supporting components, and a reset piece is connected between the ends of the two long clamps 1 close to the clamping opening 101.

[0023] The bottle clamp for a filling machine in the utility model is similar to the existing bottle clamp for a filling machine, such as the bottle clamp for a filling machine disclosed in the patent with announcement number CN220467542U. Figures 1 to 5 As shown, when the bottle clamp for a filling machine in the utility model is in use, the two long clamps 1 and the two short clamps 2 will be expanded (opened) toward the outer sides away from each other under the pulling force of the reset component, so that the distance between the two long clamps 1 and the two short clamps 2 can be increased. When the bottle to be filled moves to the clamping opening 101 between the two long clamps 1 and the two short clamps 2, the expansion component rotates. When the expansion component rotates, the rear ends of the two long clamps 1 can be pushed open to both sides. After the rear ends of the two long clamps 1 are expanded by force, the two long clamps 1 can be closed. The resetting components at the front ends of the two long clips 1 and the two short clips 2 are compressed, and then the front ends of each other are squeezed together, so that the boss of the bottle mouth can be clamped. After the filling is completed, the expansion component is reset. At this time, the two long clips 1 and the two short clips 2 will be opened again under the action of the resetting component, so that the filled bottle can be released and a new bottle to be filled can be clamped. In this way, the bottle can be clamped from the upper and lower sides of the bottle mouth boss at the same time, so as to increase the overall stability, and the clamped bottle is not easy to shake.

[0024] It should be specially noted here that the two long clips 1 and the two short clips 2 move simultaneously when they are unfolded to both sides and clamped to the middle of the bottle, so the clamping force can be guaranteed, and because the two long clips 1 and the two short clips 2 are respectively located on the upper and lower sides of the bottle mouth boss, it is equivalent to the bottle mouth boss being stuck between the two long clips 1 and the two short clips 2, so the bottle will not and cannot shake.

[0025] like Figure 3 and Figure 5 As shown, the expansion component includes a shift block 5, an elliptical block 8 and a connecting rod 9. The upper surface of the shift block 5 is fixedly connected to the bottom surface of the elliptical block 8. The upper end of the elliptical block 8 passes through the bottom plate 4 and is fixedly connected to the bottom surface of the connecting rod 9. The elliptical block 8 is located between the two long clamps 1, and the outer wall of the elliptical block 8 is against the two supporting components. The upper surface of the elliptical block 8 is fixedly connected to one side of the connecting rod 9, and the outer wall of the other end of the connecting rod 9 is fixedly connected to the inner wall of the base 3.

[0026] More specifically, when it is necessary to unfold the rear ends of the two long clips 1 to both sides, it is only necessary to rotate the shift block 5 (the shift block 5 can be driven by a motor or other driving mechanism and uniformly controlled by a PLC controller. This is a prior art and will not be described in detail). After the shift block 5 is rotated, it can drive the elliptical block 8 to rotate between the rear ends of the two long clips 1 under the support of the connecting rod 9. Due to its own shape, the elliptical block 8 will contact the supporting components of the two long clips 1 at the longer ends respectively, so that the two long clips 1 can be pushed to both sides, and then the reset components at the front ends of the two long clips 1 can be compressed, and at the same time, the front ends of the two long clips 1 can be tightened inward and clamped. When the narrower sides of the elliptical block 8 are against the supporting components of the two long clips 1, the reset components at the front ends of the two long clips 1 will unfold the front ends of the two long clips 1 to both sides, thereby releasing the bottle.

[0027] like Figure 3 and Figure 5 As shown, the support assembly includes a connecting plate 7 and a top block 10, both ends of the connecting plate 7 are fixedly connected to the inner side of the long clamp 1, one end of the top block 10 is fixedly connected to the middle of the connecting plate 7, and the other end of the top block 10 is against the outer wall of the elliptical block 8.

[0028] More specifically, by setting up the supporting assembly, firstly, the contact points between the expanding assembly and the two long clips 1 can be increased, so that the two long clips 1 can be pushed to both sides better; secondly, the elliptical block 8 can be prevented from rubbing against the two long clips 1 for a long time, thereby increasing the wear rate of the two long clips 1.

[0029] The specific method is as follows: when the elliptical block 8 rotates, it contacts with the top block 10, thereby realizing the expansion and contraction of the two long clips 1.

[0030] like Figure 3 and Figure 5 As shown, the reset member is a push spring 12, and both ends of the push spring 12 are fixedly connected to the adjacent sides of the two long clips 1 respectively.

[0031] More specifically, by setting the reset member as a push spring 12, through the characteristics of the push spring 12 itself, after the two long clamps 1 are pushed and unfolded by the expansion component and the support component, the clamping force can be maintained more quickly, accurately and effectively when the two long clamps 1 are needed to clamp the bottle in the future.

[0032] like Figure 4 As shown, a spring cavity 104 is provided on one adjacent side of the two long clips 1 , and the two ends of the push spring 12 are fixedly connected to the inner walls of the two spring cavities 104 , respectively.

[0033] More specifically, by providing the spring chamber 104, the external space occupied by the push spring 12 can be reduced, and only the distance space required for "expanding" and "pulling back" needs to be maintained.

[0034] like Figure 3 and Figure 5 As shown, two inner rods 11 are fixedly connected to the upper surface of the base plate 4, and the bottom surfaces of the two short clips 2 are fixedly connected to outer rods 13. The two outer rods 13 are respectively sleeved on the outer walls of the two inner rods 11, and the inner walls of the two inner rods 11 are rotatably connected to the rotating shafts 6. The upper ends of the two rotating shafts 6 respectively pass through the two outer rods 13 and are fixedly connected to the inner wall of the base 3.

[0035] More specifically, by setting the inner rod 11, the outer rod 13 and the rotating shaft 6, firstly, a rotation point can be given to the two long clips 1 and the two short clips 2; secondly, the two long clips 1 and the two short clips 2 can be prevented from being separated; finally, the upper base 3 and the lower bottom plate 4 can be coordinated to make the whole into a whole.

[0036] Finally, it should be noted that: through the above solution, the stability of the use of this product is increased, the service life is increased, rapid transmission operation can be achieved, and the rapid replacement of large bottle mouths of different bottle types can be met, efficiency is improved, the connection is reliable, and the operation is more stable.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
