Description

Technical Field

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

[0002] In the existing field of automated packaging technology, after the packaging container is filled, it needs to be transported to the capping station for sealing. Most capping equipment only has a simple capping function and does not have a clamping structure that is synchronized with the capping action. When the capping head presses down, it generates a reverse force, which can easily cause the container to float, slide, or shift, resulting in problems such as eccentric capping, crooked capping, and tilted capping. This leads to poor sealing consistency and low yield.

[0003] In existing technologies, such as Chinese Patent No. CN220924592U, a mounting frame is included. A motor is fixed to one side of the mounting frame surface, and a gear is fixed to the output shaft end of the motor. Two slide rods are fixed to one side of the inner wall of the mounting frame. A limit frame is slidably connected to the outside of the slide rods. A toothed rod that meshes with the outside of the gear is fixed to one side of the limit frame. A first switch and a second switch are respectively installed on the upper and lower sides of the mounting frame surface. A connecting frame is fixed to the bottom of the limit frame, and a limit block is fixedly inserted into the bottom of the connecting frame. During the capping action, the capping body can move downward at a high speed and compress the spring. However, when the lower edge of the cup lid contacts the upper edge of the cup body, the motor stops running and does not directly press against the cup body. Therefore, the entire capping action takes very little time. The capping is pressed by the spring force, and the capping process is gentle and controllable with good results, which perfectly solves the functional requirement of automatic capping in beverage machines.

[0004] While the above solution has the advantages mentioned above, its disadvantage is that the pressing head has a reaction force. If the container is not clamped synchronously, it may be pushed, shifted, or even tilted, making it impossible to press stably. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art where the pressing head has a reaction force, and if the container is not clamped synchronously, it may be pushed away, shifted, or even tilted, making it impossible to press stably.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a capping device comprising a fixed frame and a hydraulic rod mounted on the fixed frame, the capping device further comprising: a pressure applying mechanism mounted on the fixed frame for capping and sealing a packaging container filled with material; the pressure applying mechanism comprising a connecting frame mounted on the hydraulic rod and a pressure head mounted on the connecting frame for pressing the cap tightly against the packaging container to complete the sealing; a sliding rod mounted on the fixed frame, a sliding seat mounted on the sliding rod, a positioning clamp mounted on the sliding seat, and a clamping plate mounted on the positioning clamp.

[0007] In a preferred embodiment, the surface of the pressure head is provided with an elastic edging, and a No. 1 spring is provided between the clamping plate and the positioning clamp.

[0008] In this embodiment, the movement of the positioning clamp causes the clamping plate to move synchronously, eventually bringing the clamping plate into contact with the container and clamping it. With the setting of the first spring, rigid limit is provided to prevent over-clamping.

[0009] In a preferred embodiment, the pressure applying mechanism further includes a gear mounted on a fixed frame, a follower rod mounted on a connecting frame, and a drive rod slidably mounted on the fixed frame.

[0010] In a preferred embodiment, the follower rod is provided with a rack, the drive rod is provided with a rack, and the racks provided on the follower rod and the drive rod mesh with gears.

[0011] In a preferred embodiment, the pressure applying mechanism further includes a connecting rod for connecting the drive rod and the sliding seat, and a contact rod mounted on the connecting frame.

[0012] In a preferred embodiment, the capping device further includes a limiting mechanism mounted on a fixed frame to limit the travel of the cap and prevent overpressure; the limiting mechanism includes a hollow frame mounted on the fixed frame and a pin slidably mounted in the hollow frame; a second spring is provided between the pin and the hollow frame.

[0013] In this embodiment, by pulling the pin outward and stretching the second spring, the pin is disengaged from the slot, allowing the limiting rod to move normally along the hollow frame. When the rod reaches the set position, the pin is released, and the second spring drives the pin to reset, allowing the pin to re-insert into the slot and re-limit the limiting rod.

[0014] In a preferred embodiment, the limiting mechanism further includes a limiting rod slidably installed in the hollow frame and a slot formed on the limiting rod; the number of slots is at least two; the slots are matched with pins.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, the packaging container is conveyed into the capping station and positioned. The cap is automatically supplied and positioned at the container opening. Then, the pressure mechanism moves down to press the cap onto the container, completing the packaging seal. After sealing, the container is output to the next packaging process. Through the setting of the pressure mechanism, the symmetrical clamping mechanism is driven to center and clamp the container while the pressure head is pressing down to cap it. This prevents the container from slipping or tilting and ensures that the sealing material is coaxial with the pressure head, eliminating crooked caps, tilted pressure, and poor sealing.

[0017] 2. In this utility model, when the pressure head moves, it drives the contact rod to move synchronously. When it reaches the limit rod, it stops pressing down, which accurately limits the capping stroke, avoids over-pressing, damaging the cap, crushing the container, or cracking the bottle mouth. Moreover, the height of the limit rod is adjustable, which makes it suitable for containers of different heights and different pressing depth requirements, improves the versatility of the device, and facilitates quick changeovers in the packaging production line.

[0026] Example 1:

[0027] Please see Figures 1-5 This embodiment provides a capping device, the specific idea of ​​which is as follows:

[0028] The capping device includes a fixed frame 1 and a hydraulic rod 2 mounted on the fixed frame 1. The capping device also includes: a pressure applying mechanism mounted on the fixed frame 1 for capping and sealing the packaging container filled with material; the pressure applying mechanism includes a connecting frame 3 mounted on the hydraulic rod 2 and a pressure head 301 mounted on the connecting frame 3 for pressing the cap onto the packaging container to complete the sealing; a sliding rod 7 mounted on the fixed frame 1, a sliding seat 8 mounted on the sliding rod 7, a positioning clamp 9 mounted on the sliding seat 8, and a clamping plate 10 mounted on the positioning clamp 9.

[0029] In this embodiment, the specific type of the pressure-applying mechanism can be varied, and this application does not limit it. As an example, the specific arrangement of each component in an optional scheme is as follows:

[0030] In one specific implementation, the surface of the pressure head 301 is provided with an elastic edging, and a No. 1 spring 11 is provided between the clamping plate 10 and the positioning clamp 9.

[0031] In this embodiment, the clamping plate 10 is reset by the first spring 11.

[0032] The pressure application mechanism also includes a gear 4 mounted on the fixed frame 1, a follower rod 5 mounted on the connecting frame 3, and a drive rod 6 slidably mounted on the fixed frame 1.

[0033] The follower rod 5 has a rack, and the drive rod 6 has a rack. The racks on both the follower rod 5 and the drive rod 6 mesh with the gear 4.

[0034] The pressure application mechanism also includes a connecting rod 12 for connecting the drive rod 6 and the sliding seat 8, and a contact rod 13 mounted on the connecting frame 3.

[0035] In this embodiment, the packaging container is conveyed into the capping station and positioned. The cap is automatically supplied and positioned at the container opening. Then, the pressure mechanism moves down to press the cap onto the container, completing the packaging seal. After sealing, the container is output to the next packaging process.

[0036] Example 2:

[0037] like Figures 1-5 As shown, based on Embodiment 1, this embodiment also provides a capping device, the specific idea of ​​which is as follows:

[0038] The capping device also includes a limiting mechanism installed on the fixed frame 1 to limit the travel of the cap and prevent overpressure; the limiting mechanism includes a hollow frame 20 installed on the fixed frame 1 and a pin 23 slidably installed in the hollow frame 20; a second spring is provided between the pin 23 and the hollow frame 20.

[0039] In this embodiment, the second spring is used to reset the pin 23.

[0040] In this embodiment, the specific type of the limiting mechanism can be various, and this application does not limit it. As an example, the specific arrangement of each component in an optional scheme is as follows:

[0041] In one specific implementation, the limiting mechanism also includes a limiting rod 21 that is slidably installed in the hollow frame 20 and a slot 22 formed on the limiting rod 21; at least two slots 22 are provided; the slots formed in the slots 22 are matched with the pins 23.

[0042] In this embodiment, when the pressure head 301 moves, it drives the contact rod 13 to move synchronously. When it reaches the limit rod 21, it stops pressing down, which accurately limits the capping stroke, avoids over-pressing, damaging the cap, crushing the container, or cracking the bottle mouth, and the height of the limit rod 21 is adjustable.

[0043] Working principle: The packaging container is conveyed into the capping station and positioned. The cap is automatically supplied and positioned at the container opening. Then, the pressure mechanism descends, pressing the cap tightly against the container to complete the packaging seal. After sealing, the container is output to the next packaging process. Specifically: The connecting frame 3 is driven downward by the hydraulic rod 2. The movement of the connecting frame 3 drives the pressure head 301 and the contact rod 13 to move synchronously, so that the pressure head 301 contacts the cap to complete the sealing. At the same time as the connecting frame 3 moves, it also drives the follower rod 5 to move synchronously, so that the rack and pinion drive gear 4 on the follower rod 5 rotates. The rotation of gear 4 causes the drive rod 6 on the other side to move in the opposite direction along the fixed frame 1, that is, the drive rod 6 moves upward. The movement of the drive rod 6 causes the connecting rod 12 to move, which in turn causes the sliding seat 8 to move. This allows the sliding seats 8 on both sides to move along the sliding rod 7 to center their position. The movement of the sliding seat 8 causes the positioning clamp 9 to move synchronously, which in turn causes the clamping plate 10 to move synchronously. Ultimately, the clamping plate 10 contacts and clamps the container. With the rigid limit provided by the first spring 11 to prevent over-clamping and the elasticity to prevent crushing, the above structure allows the symmetrical clamping mechanism to center and clamp the container while the pressure head 301 presses down to seal it. This prevents the container from slipping or tilting and ensures that the sealing material is coaxial with the pressure head 301, thus eliminating crooked caps, tilting pressure, and poor sealing.

[0044] When the pressure head 301 moves, it drives the contact rod 13 to move synchronously. After descending and encountering the limit rod 21, it stops pressing down, which accurately limits the capping stroke and avoids over-pressing, damaging the cap, crushing the container, or cracking the bottle mouth. The height of the limit rod 21 is adjustable, which can adapt to containers of different heights and different pressing depth requirements, improves the versatility of the device, and facilitates quick changeovers in the packaging production line. Specifically, by pulling the pin 23 outward and stretching the second spring, the pin is disengaged from the slot 22. At this time, the limit rod 21 can move normally along the hollow frame 20. When it moves to the set position, by releasing the pin 23, the second spring drives the pin 23 to reset, so that the pin 23 is reinserted into the slot 22 to re-limit the limit rod 21.
