Description

Technical Field

[0001] This utility model belongs to the technical field of filling and capping equipment, specifically a bottle clamping device for filling and capping equipment. Background Technology

[0002] In filling and capping equipment, stable bottle clamping is a crucial step in ensuring filling and capping quality. Traditional filling and capping equipment often suffers from the following problems when clamping bottles: the bottle body is prone to rotation or movement during filling and capping, leading to uneven filling or loose capping; excessive clamping force may scratch or deform the bottle body, affecting the product's appearance quality. To solve these problems, existing technology proposes a bottle clamping device for filling and capping equipment to address these technical issues. Utility Model Content

[0003] To address the above problems, this utility model provides a bottle clamping device for a filling and capping equipment, which solves the technical problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A bottle clamping device for a filling and capping machine includes an active clamping arm and a driven clamping arm. The front ends of both the active and driven clamping arms are provided with irregularly shaped grooves for clamping the bottle body, and the rear ends of both arms are provided with interlocking teeth. A clamping tension spring is provided between the lower ends of the active and driven clamping arms. A collision bearing is provided at the lower end of the active clamping arm.

[0006] As a further improvement to the above scheme, silicone tubes are provided on the irregular groove, and four silicone tubes are provided; two are each on the active clamping arm and the driven clamping arm.

[0007] As a further improvement to the above solution, the outer surface of the silicone tube has an elastic buffer layer.

[0008] As a further improvement to the above scheme, a limit bolt is provided between the active clamping arm and the driven clamping arm.

[0009] As a further improvement to the above solution, a friction pad is provided at the lower end of the clamping bottle body. The friction pad is made of a material with a high coefficient of friction.

[0010] As a further improvement to the above solution, the outer surface of the impact bearing is provided with a wear-resistant coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention provides a bottle clamping device for a filling and capping machine. Through the coordinated action of the active and driven clamping arms, the bottle body is effectively clamped, preventing rotation or movement during filling and capping, thus ensuring the accuracy and stability of filling and capping. The irregular groove design at the front end of the clamping arms makes the clamping more stable, while the toothed engagement at the ends of the clamping arms enhances the reliability of the clamping. Furthermore, the use of a clamping spring ensures that the clamping arms quickly return to their initial position after release, improving the working efficiency of the equipment.

[0013] By incorporating silicone tubes into the irregularly shaped grooves, the protection of the bottle is further enhanced, preventing scratches or deformation caused by excessive clamping force during the clamping process. Four silicone tubes are used, two on the active clamping arm and two on the driven clamping arm. This design evenly distributes the clamping force, reducing localized pressure on the bottle and thus improving both the protection and the uniformity of clamping. Furthermore, an elastic buffer layer on the outer surface of the silicone tubes further enhances the protection of the bottle. This elastic buffer layer effectively absorbs and disperses the impact force generated during clamping, reducing damage to the bottle and improving the adaptability of the clamping device to bottles of different materials and shapes, thereby enhancing the versatility and reliability of the equipment.

[0014] By setting a limiting bolt between the active and driven clamping arms, the opening angle of the clamping arms is effectively limited, preventing structural damage or bottle damage caused by excessive opening of the clamping arms. The use of the limiting bolt improves the operational safety and stability of the clamping device, and also facilitates the adjustment of the opening angle of the clamping arms to accommodate bottles of different sizes.

[0015] By incorporating a friction pad made of a high-friction material at the lower end of the bottle clamping mechanism, stability during the clamping process is significantly improved. The friction pad prevents the bottle from slipping during filling and capping, thus ensuring operational precision and bottle integrity.

[0016] Applying a wear-resistant coating to the outer surface of the impact bearing significantly improves its service life and reliability. The wear-resistant coating effectively reduces wear during prolonged use, lowering maintenance costs, while also enhancing the equipment's durability and stability, ensuring long-term, efficient operation.

[0020] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0021] like Figure 1-2 As shown, the specific solution of this embodiment is as follows: a bottle clamping device for a filling and capping equipment includes an active clamping arm 1 and a driven clamping arm 2. The front ends of the active clamping arm 1 and the driven clamping arm 2 are provided with irregular grooves 10 for clamping the bottle body 3, and the ends of the active clamping arm 1 and the driven clamping arm 2 are provided with interlocking teeth. A clamping tension spring 7 is provided between the lower ends of the active clamping arm 1 and the driven clamping arm 2. A collision bearing 5 is provided at the lower end of the active clamping arm 1.

[0022] As a preferred embodiment of the above, the irregular groove 10 is provided with silicone tubes 4, and four silicone tubes 4 are provided; the active clamping arm 1 and the driven clamping arm 2 each have two.

[0023] As a preferred embodiment of the above, the outer surface of the silicone tube 4 has an elastic buffer layer.

[0024] As a preferred embodiment of the above, a limit bolt 8 is provided between the active clamping arm 1 and the driven clamping arm 2.

[0025] As a preferred embodiment of the above, a friction pad 6 is provided at the lower end of the clamping bottle body 3, and the friction pad 6 is made of a material with a high coefficient of friction.

[0026] like Figure 1 As shown, in a preferred embodiment of the above, the outer surface of the impact bearing 5 is provided with a wear-resistant coating.

[0027] Bottle placement:

[0028] 1. Chuck center:

[0029] The bottle body 3 is placed between the irregular grooves 10 of the clamping device. This position is the core area of ​​the clamping device, ensuring that the bottle body can be firmly fixed during the clamping process and will not rotate during the capping process.

[0030] 2. Between the clamps:

[0031] Both the active clamping arm 1 and the driven clamping arm 2 have teeth at their ends. Under the action of the clamping spring 7, these two clamping arms can tightly clamp the bottle body 3. The bottle body 3 is clamped between the two clamping arms, ensuring that it is in the center position of the clamping device.

[0032] Related structural descriptions:

[0033] 1. Active clamping arm 1:

[0034] The active clamping arm 1 is one of the main components of the clamping device. Its end is provided with teeth for cooperating with the driven clamping arm 2 to clamp the bottle body 3. The active clamping arm 1 is also provided with a collision bearing 5, which is used to control the opening and clamping of the clamping arm under the action of the collision block cam 9.

[0035] 2. Driven clamping arm 2:

[0036] The driven clamping arm 2 is also one of the main components of the clamping device. Its end is also provided with teeth for cooperating with the active clamping arm 1 to clamp the bottle body 3. Under the action of the clamping spring 7, the driven clamping arm 2 works together with the active clamping arm 1 to ensure that the bottle body 3 is firmly fixed.

[0037] 3. Silicone tubing 4:

[0038] The silicone tube 4 is set on the irregular groove 10 at the front end of the active clamping arm 1 and the driven clamping arm 2, which serves as a buffer. When the active clamping arm 1 and the driven clamping arm 2 clamp the bottle body 3, the silicone tube 4 can prevent the bottle body 3 from being scratched or deformed due to excessive clamping force, and can also adapt to bottles of different sizes and materials.

[0039] 4. Friction pad 6:

[0040] A friction pad 6 is positioned at the bottom of the bottle body 3 to increase friction with the surface. During clamping, the friction pad 6 contacts the bottle body 3, ensuring that the bottle body 3 does not slip within the clamping device, further improving clamping stability. The friction pad 6 is positioned on a tray.

[0041] 5. Clamping spring 7:

[0042] A clamping spring 7 connects between the active clamping arm 1 and the driven clamping arm 2, providing clamping force. In the initial state, the clamping spring 7 keeps the active clamping arm 1 and the driven clamping arm 2 clamped. When the impact bearing 5 rotates to the impact cam 9, the clamping arms open, and the bottle enters the center of the clamp. After the clamp leaves the impact cam 9, the elastic force of the clamping spring 7 causes the active clamping arm 1 and the driven clamping arm 2 to automatically clamp together, fixing the bottle body 3.

[0043] During the work process:

[0044] 1. Initial state:

[0045] In the initial state, the active clamping arm 1 and the driven clamping arm 2 are kept clamped by the clamping spring 7, and the clamp is in an idle state, waiting for the bottle to enter.

[0046] 2. Bottle enters:

[0047] As the bottle moves to the vicinity of the chuck along the bottle inlet / outlet dial, the collision bearing 5 in the active gripper arm 1 rotates to the collision cam 9, causing the gripper arm to open according to the curve of the collision cam 9, providing space for the bottle to enter. After the bottle enters the chuck, it is located in the center position of the chuck.

[0048] 3. Clamping and fixing:

[0049] After the handover is completed, the clamp moves away from the contact block cam 9, and the active clamping arm 1 and the driven clamping arm 2 automatically clamp under the action of the clamping spring 7, firmly fixing the bottle in the center position of the clamp and preventing the bottle body 3 from rotating during the capping process.

[0050] 4. Capping process:

[0051] During the capping process, the bottle is firmly fixed in the center of the clamp by the clamping device, preventing it from rotating and ensuring the smooth operation of the capping.

[0052] 5. Bottle delivery:

[0053] After the cap is screwed on, the chuck moves back to the contact cam 9, and the collision bearing 5 opens the clamp arm again according to the curve of the contact cam 9, and the bottle is sent out of the chuck to enter the next process.

[0054] Through the above structure and working process, the bottle body is firmly fixed at the center position of the clamping device, ensuring the stability and reliability of the capping process.
