Description

Technical Field

[0001] The utility model relates to the technical field of bottle cap production auxiliary equipment, in particular to a cap cutting machine. Background Art

[0002] During the production process of bottle caps, there is an inner plug structure on the inside of the bottle cap, which will be plugged into the inside of the bottle mouth to form a seal. Due to processing errors, the inner plug will form defects such as incompleteness and pits, which will cause air leakage and liquid leakage during filling.

[0003] Therefore, after the bottle cap is formed, the inner plug needs to be separated from the cap body and then inspected. The existing method of separating the inner plug from the cap body is for workers to manually separate them with a knife (usually a utility knife). This method has a large error due to the influence of manual operation. Secondly, workers are prone to slipping during the operation and get injured, and the separation efficiency is low.

When the rotating seat rotates, the tool is driven to rotate and cut the inner plug of the bottle cap.

[0007] Furthermore, the rotating seat is a circular plate structure, the bottom of the rotating seat is connected to the mechanical rotation through a rotating shaft, the circumferential wall of the rotating seat is provided with teeth, a driving motor is provided in the chassis, and the output shaft of the driving motor is transmission-connected with a driving gear meshing with the teeth.

[0008] Furthermore, the fixing seat is a circular plate structure, a circular through hole is coaxially provided in the middle of the fixing seat, and the inner wall of the circular through hole is provided with a vertical groove adapted to the vertical ribs on the outer wall of the bottle cap.

[0009] Furthermore, the fixing base is detachably connected to the chassis.

[0010] Furthermore, the fixing base is connected to the chassis via bolts.

[0011] Furthermore, a spring is coaxially provided on a surface of the rotating seat close to the fixed seat.

[0012] Furthermore, the tool is triangular in shape.

[0013] The beneficial effects of the utility model are:

[0014] The utility model separates the inner plug from the bottle cap through mechanical equipment, thus avoiding the risk of hand injury caused by manual cap cutting and improving the cap cutting efficiency; and when the inner plug is cut off, the spring automatically pushes the inner plug out to realize automatic discharging.

[0020] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0022] Example:

[0023] like Figure 1-Figure 4 As shown, a cap cutting machine includes a chassis 1, a fixed seat 3 arranged on the chassis 1 and a rotating seat 2 arranged in the chassis 1, wherein the fixed seat 3 is used to fix the bottle cap, the rotating seat 2 is arranged below the fixed seat 3, and a vertical tool 4 is provided on the rotating seat 2. When the rotating seat 2 rotates, the tool 4 is driven to rotate and cut the inner plug of the bottle cap.

[0024] like Figure 2 and Figure 3As shown, the rotating seat 2 is a circular plate structure, the bottom of the rotating seat 2 is connected to the mechanical rotation through a rotating shaft, the circumferential wall of the rotating seat 2 is provided with teeth, and a driving motor 5 is provided in the chassis 1. The output shaft of the driving motor 5 is transmission-connected with a driving gear 6 that meshes with the teeth.

[0025] The fixing seat 3 is a circular plate structure, a circular through hole 7 is coaxially provided in the middle of the fixing seat 3, and a vertical groove 9 adapted to the vertical ribs on the outer wall of the bottle cap is provided on the inner wall of the circular through hole 7.

[0026] The fixing base 3 is detachably connected to the chassis 1 .

[0027] The fixing base 3 is connected to the chassis 1 via bolts.

[0028] A spring 8 is coaxially disposed on a surface of the rotating seat 2 close to the fixed seat 3 .

[0029] like Figure 4 As shown, the cutter 4 is triangular in shape, with the tip of the cutter 4 facing upward.

[0030] Among them, 1. The diameter of the circular through hole 7 is adapted to the outer diameter of the bottle cap to be cut. 2. The tip of the cutter 4 corresponds to the edge of the inner plug, and the cutter 4 cuts off the inner plug when rotating.

[0031] Working principle: manually press the bottle cap into the circular through hole 7, during which the vertical ribs on the outer circumferential wall of the bottle cap enter the vertical groove 9; then press the bottle cap until the cutter 4 pierces the bottle cap. After the bottle cap enters the circular through hole 7, the friction between the outer circumferential wall of the bottle cap and the hole wall of the circular through hole 7, and the friction between the vertical ribs of the bottle cap and the vertical groove 9 can prevent the bottle cap from rebounding and fix the bottle cap. At the same time, the cooperation between the vertical ribs and the vertical groove 9 can prevent the bottle cap from moving when the cutter 4 rotates and cannot complete the cap and plug separation.

[0032] The driving motor 5 is started, and the driving motor 5 drives the rotating seat 2 to rotate. When the rotating seat 2 rotates, the cutter 4 is driven to rotate, and the cutter 4 rotates to cut the inner plug along the circumferential direction. Since the cut inner plug has no limit, it is ejected under the reset action of the spring 8, realizing the automatic unloading of the inner plug. The remaining bottle caps can be taken out manually after stopping the machine.

[0033] The utility model separates the inner plug from the bottle cap through mechanical equipment, thus avoiding the risk of hand injury caused by manual cap cutting and improving the cap cutting efficiency; and when the inner plug is cut off, the spring automatically pushes the inner plug out to realize automatic discharging.

[0034] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
