Description

Technical Field

[0001] This utility model relates to the field of bottle capping machine technology, specifically to an auxiliary device for disassembling the plunger of a bottle capping machine. Background Technology

[0002] Bottle capping machines are key pieces of equipment in liquid packaging production lines. They are responsible for quickly sealing crown caps (or similar caps) onto the necks of filled containers, applying pressure to complete the cap sealing. The core actuator of the bottle capping machine is the capping plunger, which is responsible for pressing the cap onto the bottle neck. Figure 1 As shown, the main body of the capping plunger includes a plunger rod made of high-strength stainless steel, which performs precise linear motion within a guide sleeve. An auxiliary spring 10 and a pressure spring 11 are fitted around the plunger rod. A punch head 12 is located at the bottom of the plunger rod, directly contacting the top of the bottle cap. Because the capping plunger integrates precision mechanics and pressure control technologies, it is necessary to ensure the stability, accuracy, and reliability of the capping plunger's operation when using a bottle capping machine. Daily production requires adjustment and regular maintenance of the capping plunger. Due to the relatively large spring forces of the auxiliary spring 10 (approximately 100 kg) and the pressure spring 11 (approximately 180-200 kg), these springs pose a risk of rebound during maintenance and disassembly of the capping plunger, making the disassembly work time-consuming and labor-intensive, and posing a significant safety risk.

[0003] Based on the above problems, the technical solution of this application is proposed. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the present invention provides an auxiliary device for disassembling the plunger of a bottle capping machine. It has a simple structure and is easy to use. It can avoid spring rebound during the disassembly of the capping machine plunger, thereby reducing the difficulty of disassembly and labor costs.

[0005] To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model discloses an auxiliary device for disassembling the plunger of a bottle capping machine, including a base body with an internal cavity, a snap-fit ​​component placed at one end of the base body, and a pressing component placed at the other end of the base body. The cavity is used to horizontally accommodate the capping machine plunger. The snap-fit ​​component is used to snap the top of the capping machine plunger. The pressing component contacts the punch head at the end of the capping machine plunger through rotational movement and then abuts against the punch head, so that the spring on the plunger rod sleeved on the capping machine plunger can slowly release its elastic force and prevent the spring from rebounding quickly.

[0006] Preferably, the base body is a rectangular structure with an opening at the top formed by a bottom plate, a left side plate, a right side plate and a top plate. The top plate is connected to one end of the left side plate and the right side plate. The other ends of the left side plate and the right side plate are respectively provided with corresponding through holes. The snap-fit ​​component passes through the through holes and is fastened to the left side plate and the right side plate.

[0007] Preferably, the snap-fit ​​component includes a bolt and a pair of nuts, wherein the bolt passes through the opposing through holes and is then tightened from the outside by the pair of nuts.

[0008] Preferably, the clamping component includes a rotating handle, a screw with external threads connected to the end of the rotating handle, and a clamping shaft connected to the end of the screw. The top plate has a threaded hole at its center. The screw passes through the threaded hole into the receiving cavity and rotates. The rotation of the screw drives the clamping shaft to reciprocate linearly along the central axis of the base body to press against the punch head.

[0009] Preferably, the end of the clamping shaft away from the screw is provided with a protrusion that matches the shape of the punch head, and the protrusion abuts against the punch head.

[0010] Preferably, the protrusion is circular in shape.

[0011] Preferably, the screw is fastened to the inner side of the top plate by a nut.

[0012] Preferably, the rotating handle is movably connected to the screw, and the two are arranged perpendicularly.

[0013] Preferably, a fixing cylinder is provided in the receiving cavity below the snap-fit ​​component, the fixing cylinder cooperating with the snap-fit ​​component to jointly lock the top of the capping machine plunger.

[0014] Preferably, the bolt of the snap-fit ​​component is M16*160, and the nut of the snap-fit ​​component is M16.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The auxiliary device for disassembling the plunger of a bottle capping machine provided by this utility model has a horizontal receiving cavity in the base body for accommodating the capping machine plunger. The top of the capping machine plunger is held in place by a snap-fit ​​component, and the end of the capping machine plunger is pressed against by a clamping component. This allows the spring on the plunger rod to release its elastic force slowly, avoiding rapid spring rebound and reducing the safety risk of disassembling the capping machine plunger. It also reduces labor intensity, saves manpower, and improves the work efficiency of maintenance personnel.

[0016] The following will further explain the concept, specific structure and technical effects of this utility model in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of this utility model. Attached Figure Description

[0021] This embodiment discloses an auxiliary device for disassembling the plunger of a bottle capping machine, such as... Figure 2 and Figure 3 As shown, the device includes a base body 1 with an internal cavity, a snap-fit ​​component at one end of the base body 1, and a clamping component at the other end of the base body 1. The cavity is used to horizontally accommodate the capping machine plunger, and the snap-fit ​​component is used to clamp the plunger. Figure 1 The top of the capping machine plunger shown is pressed against the punch head 12 at the end of the capping machine plunger by the rotating motion of the pressing component. This allows the spring on the plunger rod of the capping machine plunger to slowly release its elastic force, preventing the spring from rebounding quickly.

[0022] The base body 1 is a rectangular structure with an opening at the top, formed by a bottom plate, a left side plate, a right side plate, and a top plate. The top plate is connected to one end of the left side plate and the right side plate. The other ends of the left side plate and the right side plate are respectively provided with opposing through holes. The snap-fit ​​component passes through the through holes and is fastened to the left side plate and the right side plate. The snap-fit ​​component includes a bolt 6 and a pair of nuts 7. After the bolt 6 passes through the opposing through holes, it is fastened by the pair of nuts 7 from the outside of the left side plate and the right side plate, respectively. In order to further lock the top of the capping machine plunger, a fixing cylinder 2 is provided in the receiving cavity below the snap-fit ​​component. The fixing cylinder 2 cooperates with the snap-fit ​​component. The fixing cylinder 2 provides support from the bottom, and the bolt 6 locks the capping machine plunger from the top. The bolt 6 and the fixing cylinder 2 work together from two directions to lock the top of the capping machine plunger. In one example, the bolt 6 of the snap-fit ​​component is M16*160, that is, the bolt 6 is a metric bolt with threads, a diameter of 16mm and a length of 160mm, and the nut 7 of the snap-fit ​​component is M16, that is, the nut 7 is a metric thread with a diameter of 16mm.

[0023] The clamping component is located at the other end of the base body 1. The clamping component includes a rotating handle 5, a threaded screw 4 connected to the end of the rotating handle, and a clamping shaft 3 connected to the end of the screw 4. The rotating handle 5 and the screw 4 are movably connected and arranged perpendicularly. A threaded hole is provided at the center of the top plate. The screw 4 passes through the threaded hole and enters the receiving cavity. The screw 4 is fastened to the inner side of the top plate by a matching nut. The rotation of the screw 4 drives the clamping shaft 3 to reciprocate linearly along the central axis of the base body 1, thereby pressing against the punch head 12. The end of the clamping shaft 3 away from the screw 4 has a protrusion that matches the shape of the punch head 12. The circular protrusion presses against the punch head 12. In one example, the protrusion has a diameter of 20mm and a length of 10mm, the clamping shaft 3 has a diameter of 42mm and a length of 60mm, the clamping shaft 3 is engaged with the screw 4, and the screw 4 is movably connected with the rotating handle part 5.

[0024] In use, the capping plunger of the bottle capping machine is placed horizontally in the receiving cavity of the base body 1. The top of the capping plunger is engaged with the screw 4 of the locking component, and its bottom is in contact with the fixing cylinder 2. Then, the rotating handle 5 is rotated so that the clamping shaft 3 moves closer to the end of the capping plunger. When the protrusion at the end of the clamping shaft 3 abuts against the punch head 12, the rotation of the rotating handle 5 is stopped. The protrusion abutting against the punch head 12 can fix the plunger rod of the capping plunger, help the spring on the plunger rod to release its elasticity, prevent the spring from rebounding, and reduce the burden of disassembly work. After using the auxiliary device in this embodiment, the disassembly work of the capping plunger, which originally required 3 people to assist in disassembly and assembly, can be performed by 1 person. This not only saves 2 people, but also saves 15 minutes for each disassembly and assembly work. This reduces labor intensity, saves manpower, improves the work efficiency of maintenance personnel, and reduces the risk of maintenance safety operations.

[0025] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
