Description

Technical Field

[0001] The utility model relates to the field of bottle cap processing, in particular to a bottle cap circular cutting blade. Background Art

[0002] Bottle cap is a commonly used seal, which is essential in the beverage, water, oil and other industries. The bottom of the bottle cap is usually integrated during production. In order to facilitate consumers to unscrew the bottle cap flexibly, a cut is usually made at the bottom of the outer circular edge of the bottle cap to make it a breakpoint structure to connect the anti-theft ring. This can ensure that the product is sealed intact when it leaves the factory as a finished product, and the bottle cap remains intact during transportation, and can be easily unscrewed when used. On the one hand, a connecting bridge is needed to protect the bottle cap, and on the other hand, the bottle cap needs to be able to be opened easily. Therefore, the installation and cutting accuracy of the ring cutting machine blade for cutting the connecting bridge are required to be high.

[0003] The prior art CN201922431556.7 discloses a new type of bottle cap ring cutting knife, including a handle and a large blade; the handle is in a "convex" shape, the upper end of the handle is integrally formed with the large blade, and a screw hole is provided on the handle; the large blade includes a small blade and a V-shaped groove; the V-shaped groove has two groove walls; the large blade is in an arc shape; the handle thickness is 0.62mm; the large blade length is 166mm, the width is 2.3mm, and the thickness is 0.1mm; the small blade length is 11.2mm; the outermost width of the V-shaped groove is 0.72mm, and the width of the middle position is 0.45mm; the ring cutting knife is made of high-speed steel; although the utility model improves the stability of the ring cutting through the V-shaped groove, the following problems still exist:

[0004] 1. The V-groove design requires a high precision in the installation position of the blade. If the blade is extended too far, the connecting bridge may be cut off easily. If the blade is close to the inside, the connecting bridge may be reserved too much, making it difficult to open the bottle cap and affecting the user experience.

[0005] 2. The blade thickness is only 0.1mm, which is conducive to the fineness of cutting, but may reduce the durability and wear resistance of the blade. Especially in a large number of continuous cutting operations, thin blades are more likely to become blunt or damaged, increasing the frequency of replacement, affecting production efficiency and cost control.

[0006] 3. The utility model cuts by pressing the bottle cap against the blade, mainly using pressure to cut out a notch, which can easily cause burrs or deformation on the cut, affecting the appearance and sealing performance of the bottle cap. Utility Model Content

[0007] In view of this, the purpose of the utility model is to provide a bottle cap circular cutting blade, which uses an electric heating wire to preheat the blade so that it can cut into the bottle cap more easily and effectively prevent the generation of burrs during cutting.

A through hole is provided along the axial direction of the knife blade at the connection between the knife blade and the knife body, and a heating wire capable of heating the knife blade is provided in the through hole.

[0011] It should be noted that the trapezoidal knife groove can keep the bottle cap connection bridge as small as possible, thereby reducing the torque of the bottle cap and making it easier to open the bottle cap. The blade is preheated by the electric heating wire to reduce cutting resistance, making the cutting process smoother, reducing burr formation, and improving the quality of the finished product.

[0012] Preferably, the heating temperature of the heating wire is 80-120°C.

[0013] It should be noted that the temperature range of 80-120℃ ensures that the electric heating wire can effectively preheat the blade without overheating, keeping the blade within the ideal cutting temperature range, which can not only soften the cutting material, but also avoid overheating and damage to the blade, thereby improving cutting efficiency and quality.

[0014] Preferably, the blade is composed of a plurality of small blades, the small blades and the blade grooves are alternately arranged on the blade body, and the thickness of the small blades decreases gradually toward both sides.

[0015] It should be noted that the distribution of cutting force is optimized through the gradually changing thickness distribution of the small blade, and by cooperating with the trapezoidal knife groove, the connection area can be kept as small as possible, so that the torque for opening the bottle cap can be kept within a small range.

[0016] Preferably, the transverse cross section of the small blade from left to right is rhombus-shaped, and the cross section from inside to outside is conical.

[0017] It should be noted that the diamond and conical design of the small blade cross-section increases the contact area of ​​the blade surface, can have better cutting effects in different directions, improve cutting efficiency, reduce material adhesion, and reduce cutting resistance and wear.

[0018] Preferably, a wear-resistant layer is provided on the small blade by electroplating.

[0020] Preferably, the front end of the blade body is in an annular shape as a whole, the blade is arranged on the inner arc surface of the blade body, and the blade is in an arc shape as a whole.

[0021] It should be noted that the circular blade body and the corresponding curved blade can match the shape of the bottle cap, ensuring a high degree of fit during cutting, reducing vibration, and improving cutting stability and accuracy.

[0022] Preferably, the bottom width of the knife groove is 0.2-0.4 mm, and the upper width is 0.6-0.8 mm.

[0023] It should be noted that the knife groove width design can help control the cutting depth, effectively control the connection area of ​​the bottle cap connecting bridge, maintain the uniformity of the incision, and effectively prevent the connection bridge from breaking, thereby improving product quality.

[0024] Preferably, the number of the knife grooves is 12-16.

[0025] It should be noted that the number of the bottle cap connecting bridges is controlled by controlling the number of the knife grooves, thereby controlling the torque required for opening the bottle cap.

[0026] Preferably, the positioning holes are waist-shaped holes, which are correspondingly arranged on the left and right sides of the blade body.

[0027] It should be noted that the waist-shaped hole design can accurately install and adjust the position of the blade, ensure the consistency of each cutting, and improve the overall processing accuracy and stability.

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 ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Example 1

[0038] like Figure 1-Figure 4 As shown, a bottle cap circular cutting blade comprises: a blade body 1, a blade edge 2 and a blade groove 3; the blade body 1 is provided with a positioning hole 4, the blade edge 2 is arranged on the edge of the blade body 1, and the blade groove 3 is arranged at intervals on the blade edge 2.

[0039] The blade groove 3 is trapezoidal in shape as a whole, and its two sides are opened from inside to outside. A through hole 6 is provided along the axial direction of the blade 2 at the connection between the blade 2 and the blade body 1, and a heating wire 5 capable of heating the blade 2 is provided in the through hole 6.

[0040] The heating temperature of the heating wire 5 is 100°C.

[0041] The blade 2 is composed of a plurality of small blades 21 , and the small blades 21 and the blade grooves 3 are alternately arranged on the blade body 1 , and the thickness of the small blades 21 decreases gradually toward both sides.

[0042] The transverse cross section of the small blade 21 from left to right is rhombus-shaped, and the cross section from inside to outside is conical.

[0043] The small blade 21 is provided with a wear-resistant layer by electroplating.

[0044] The front end of the blade body 1 is in a circular ring shape as a whole, the blade 2 is arranged on the inner arc surface of the blade body 1, and the blade 2 is in an arc shape as a whole.

[0045] The bottom width of the knife groove 3 is 0.3 mm, and the upper width is 0.8 mm.

[0046] The number of the knife grooves 3 is 14.

[0047] The positioning holes 4 are waist-shaped holes, which are correspondingly arranged on the left and right sides of the blade body 1 .

[0048] Working principle and use method of a bottle cap circular cutting blade of this embodiment:

[0049] The bottle cap ring cutting blade provided in the present embodiment heats the blade 2 through the electric heating wire 5 in the blade body 1, and the temperature is controlled at 100°C, which can enable the blade 2 to soften the bottle cap 7 when contacting the bottle cap 7, reduce cutting resistance, reduce burr formation, and avoid damage to the blade 2 due to overheating; the trapezoidal structure of the knife groove 3 and the design of opening to both sides help to make the connecting bridge 71 between the anti-theft ring 72 and the bottle cap 7 smaller during cutting, reduce the torque requirement of the bottle cap 7, and make the bottle cap 7 easier to open; the blade 2 is composed of a plurality of small blades 21, which are staggered along the knife groove 3, and the thickness decreases on both sides to form a cross-section from rhombus to cone. This design optimizes the distribution of cutting force, improves cutting efficiency, reduces material adhesion and wear, and ensures a smooth cutting surface; after electroplating treatment, a wear-resistant layer is added, which greatly improves the wear resistance of the blade, extends the service life, reduces the replacement frequency, and improves production efficiency.

[0050] When in use, first accurately install the blade on the ring cutting machine through the waist-shaped positioning hole 4 to ensure that the blade is aligned with the machine, adjust the position of the blade through the positioning hole 4 to make it consistent with the expected cutting path, start the equipment, and the electric heating wire 5 starts to work, preheating the blade 2 to the set temperature. After waiting for the preheating to be completed, the bottle cap 7 to be cut is sent under the blade. As the bottle cap 7 rotates along the blade 2, the blade 2 easily cuts into the bottle cap 7 material under the action of the preheating of the electric heating wire 5, and works together with the small blade 21 structure in the trapezoidal knife groove 3 to form a uniform cutting surface and reduce burrs. After the cutting is completed, a uniform connecting bridge 71 structure is formed on the bottle cap 7 to ensure that the bottle cap 7 remains sealed when leaving the factory, and the connecting bridge 71 connecting the anti-theft ring 72 can maintain a small contact area, which can be easily unscrewed when in use.
