Description

Technical Field

[0001] This utility model relates to the technical field of packaging equipment, and in particular to a novel capping device. Background Technology

[0002] Currently, most bottled wines and beverages on the market use twist-off aluminum caps. These caps are typically made by pressing the bottle opening with sealing equipment to seal the bottle opening. Capping equipment is widely used in the pharmaceutical and food industries.

[0003] However, with product iterations and rapid changes in packaging, especially the varying diameters of bottle openings, capping has become a challenge. Therefore, capping machines with adjustable capping blades have emerged in the market. Existing technology, patent number "CN222434118U," discloses a double-circular-blade capping machine. This machine uses a second motor to drive a transmission screw, which in turn moves two sets of screw nuts closer or further apart. The movement of these screw nuts moves the capping blades, allowing for adjustment of the distance between the blades to facilitate capping of bottles with different diameters. While this structure allows for adjustment of the distance between caps, it is cumbersome, structurally complex, and has low production efficiency.

[0004] Therefore, there is an urgent need for a capping machine that is highly applicable, simple in structure, and has high production efficiency. Utility Model Content

[0024] Please see Figures 1 to 5 This utility model provides a novel capping device 1000, which includes a mounting plate 1 connected to an external device, a pressure rod mechanism 2 mounted on the mounting plate 1, and a capping mechanism 3 rotatably mounted below the mounting plate 1.

[0025] The pressure rod mechanism 2 includes an inner rod 21 that passes through the mounting plate 1 and reciprocates along its own length, and a sleeve rod 22 fitted onto the bottom of the inner rod 21. The capping mechanism 3 includes a sealing blade assembly 31 with a shrinkable sealing radius and a guide assembly 32 installed below the mounting plate 1.

[0026] Specifically, the guide assembly 32 includes a guide sleeve 321 that is slidably sleeved on the sleeve rod 22 and a guide ring 322 that is sleeved on the upper part of the encapsulation knife assembly 31. The bottom of the guide sleeve 321 gradually contracts and rolls to connect with the top of the encapsulation knife assembly 31.

[0027] In addition, the mounting plate 1 is also equipped with a drive unit 4 for driving the roll-up mechanism 3 to rotate.

[0028] Preferably, the top of the encapsulation knife assembly 31 is provided with a roller that abuts against the bottom of the guide sleeve 321. Of course, the embodiments of this utility model are not limited in this respect. In an alternative embodiment, the top of the encapsulation knife assembly 31 is rolled to the bottom of the guide sleeve 321 by a ball bearing.

[0029] Please continue reading. Figures 2 to 5 The sealing knife assembly 31 includes a fixing block 311 sleeved on the sleeve rod 22 and a plurality of crimping cutters 312 spaced apart from each other around the outer circumference of the sleeve rod 22. Preferably, the number of crimping cutters 312 is 3 sets, and the two adjacent crimping cutter sets are evenly distributed on the outer circumference of the sleeve rod 22 at an angle of 120°.

[0030] Specifically, the fixing block 311 includes several fulcrums 3111 corresponding to the capping cutter 312, and the fulcrums 3111 are hinged to the capping cutter 312.

[0031] The roll-up cutter 312 includes a clamping rod 3121 constrained by a guide ring 322, a bottom rod 3122 hinged to the clamping rod 3121, and a roll-up cutter 3123 detachably mounted on the bottom of the bottom rod 3122.

[0032] Furthermore, the clamping rod 3121 includes a guide portion 31211 that is rolledly connected to the bottom of the guide ring 322, a clamping portion 31212 that is elastically connected to the middle of the bottom rod 3122, and a connecting portion 31213 that is connected to both of them at both ends. The connecting portion 31213 is hinged to the top of the bottom rod 3122 and the fulcrum 3111.

[0033] In this application, the hinge point of fulcrum 3111, connecting part 31213 and bottom rod 3122 is used as the support point. By utilizing the relative displacement between guide sleeve 321 and sleeve rod 22, the sealing radius of the capping cutter 312 is automatically reduced using the lever principle. At the same time, the elastic connection between clamping rod 3121 and bottom rod 3122 enables the adaptive adjustment of the sealing radius of the sealing cutter assembly 31 within its applicable range.

[0034] Please continue reading. Figure 4 The pressure rod mechanism 2 also includes a connecting rod 23 sleeved in the upper part of the inner rod 21.

[0035] Specifically, the connecting rod 23 passes through the mounting plate 1 and is rotatably mounted on the mounting plate 1 via a bearing flange. One end of the connecting rod 23 extends into the guide sleeve 321 and rotates coaxially with the guide sleeve 321; the other end is provided with a gear shaft, which is connected to the output end of the drive unit 4 via a synchronous belt. In this embodiment, the drive unit 4 is a drive motor, and its output end is connected to the gear shaft on the connecting rod 23 via a synchronous belt.

[0036] Furthermore, a stop block 211 is fitted onto the top of the inner rod 21. The stop block 211 abuts against the top of the connecting rod 23 to prevent relative displacement between the inner rod 21 and the connecting rod 23. Preferably, a thrust ball bearing 212 is provided between the stop block 211 and the top of the connecting rod 23 to counteract axial loads.

[0037] Please continue reading. Figure 4 One end of the guide sleeve 321 is fitted onto the bottom of the connecting rod 23, and the other end is slidably fitted onto the top of the sleeve rod 22.

[0038] The guide sleeve 321 contains an elastic element 24 that is connected to the top of the sleeve rod 22.

[0039] Please continue reading. Figure 4 The capping mechanism 3 also includes a sealing structure 33 located at the bottom of the inner rod 21.

[0040] Specifically, the sealing structure 33 includes a pressure head 331 connected to the bottom of the inner rod 21 and a bushing 332 for connecting the inner rod 21 and the pressure head 331.

[0041] Among them, one end of the bushing 332 is located at the bottom of the sleeve rod 22, and the other end is equipped with a bearing sleeved on the pressure head 331.

[0042] Please continue reading. Figure 1 The mounting plate 1 is equipped with a lifting mechanism 5 that drives the mounting plate 1 to move up and down. The lifting mechanism 5 is connected to external equipment, such as a robotic arm.

[0043] In addition, this application also includes a protective cover 6, which is mounted on the mounting plate 1.

[0044] The implementation principle of the novel capping device 1000 in this utility model is as follows: when the packaging bottle to be capped moves to the bottom of the device, the lifting mechanism 5 drives the mounting plate 1 to move down, thereby driving the pressure rod mechanism 2 and the capping mechanism 3 to move down; then, the pressure head 331 on the sealing structure 33 abuts against the bottle mouth, and the pressure head 331 applies a reaction force to the sleeve rod 22 and the inner rod 21, causing the inner rod 21 and the sleeve rod 22 to move upward, thereby generating a relative displacement between the guide sleeve 321 and the top of the sleeve rod 22, and the bottom of the guide sleeve 321 further abuts against the top of the sealing knife assembly 31; The capping cutter 312 uses the hinge point between the fulcrum 3111, the connecting part 31213, and the bottom rod 3122 as a support point. Utilizing the "lever principle," the clamping rod 3121 retracts inward, further allowing the capping cutter 3123 on the bottom rod 3122 to retract inward until it abuts against the outer circumference of the bottle opening. Subsequently, the output end of the drive unit 4 drives the connecting rod 23 to rotate via a synchronous belt. The connecting rod 23 drives the guide sleeve 321, the sleeve rod 22, the fixing block 311 sleeved on the sleeve rod 22, and the capping cutter 312 to rotate, thereby completing the capping of the packaging bottle. After the sealing is completed, the drive unit 4 stops driving, the lifting mechanism 5 gradually lifts, and the elastic element 24 retracts the sleeve rod 22 along the length of its inner rod 21 back to its original position. The relative displacement between the top of the guide sleeve 321 and the sleeve rod 22 disappears, and the capping cutter 312 in the sealing cutter group 31 also retracts to its original position. The capped packaging bottle is removed, awaiting the next packaging bottle to be capped.

[0045] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
