Technical Field

[0001] The present application relates to the technical field of rubber cutting, and in particular to a rubber tapping blade. Background Art

[0002] At present, various blades of electric rubber knives, rubber tapping machines and other equipment are mainly based on the L-shaped blade design, incorporating the concept of collaborative work between the main and auxiliary blades, making rubber tapping more efficient. For example, the utility model patent with application number CN202321579900.7 discloses a rubber tapping blade, and specifically discloses: A rubber tapping blade of the utility model includes a blade body, the blade body is L-shaped, and the blade body includes a main blade and an auxiliary blade formed by bending the main blade. It can be seen from this that in the prior art, the main blade is only bent to form the auxiliary blade, and the bend is at a right angle to the horizontal line, which results in thick wood chips easily being retained on the cut surface of the rubber tree when cutting the bark and not easily falling off. Utility Model Content

[0003] The technical problem to be solved by the present application is to provide a rubber tapping blade that can reduce the amount of bark debris falling on the rubber surface, improve the flow of latex, and minimize the contact area between the rubber tapping blade and the cut surface of the rubber tree, thereby increasing latex production.

[0004] In order to solve the above technical problems, this application adopts the following technical solutions:

[0005] The present application provides a rubber tapping blade, comprising: a main blade and an auxiliary blade connected to each other, wherein the main blade and the auxiliary blade are bent relative to each other, and an angle formed by a fold line at the bending position and a horizontal line is a first angle, and the first angle is an acute angle.

[0006] In the process of implementing the above technical solution, the tapping blade includes a main blade and a secondary blade connected to each other, the main blade and the secondary blade are bent to each other, and the angle formed by the fold line formed by the bending position and the horizontal line is the first angle, and the first angle is an acute angle, so that when the tapping is placed horizontally, the secondary blade is in an inclined structure relative to the main blade. In this way, the debris formed after the main blade cuts the bark is discharged outside the tapping surface through the guiding effect of the secondary blade, so that the debris is prevented from falling on the tapping surface to affect the flow of latex or cause latex overflow, affecting the latex yield, and at the same time, the debris is prevented from falling into the tapping bowl to cause latex contamination.

[0007] As an embodiment, the main blade is configured to gradually widen from a position connected to the auxiliary blade toward a direction away from the position connected to the auxiliary blade.

[0008] During the implementation of the above technical solution, the main blade is gradually widened from the connection position with the auxiliary blade to the direction away from the connection position with the auxiliary blade, reducing the contact area between the main blade and the cutting surface, thereby reducing the pressure and friction of the main blade on the new cutting surface, thereby reducing the probability of new severed latex ducts being blocked and increasing the glue output.

[0009] As an embodiment, the main blade is provided with a main cutting surface, and the secondary blade is provided with a secondary cutting surface.

[0010] In the process of implementing the above technical solution, the main blade is provided with a main cutting surface, and the secondary blade is provided with a secondary cutting surface. The main cutting surface and the secondary cutting surface cooperate with each other, thereby improving the cutting efficiency; and the secondary cutting surface can cut off the old rubber line remaining on the cutting surface, thereby preventing the old rubber line from affecting the discharge of latex.

[0011] As an embodiment, the tapping blade further includes a fixing portion, the fixing portion is connected to the main blade, and the fixing portion is provided with a through hole for fixing to the cutting equipment.

[0012] In the process of implementing the above technical solution, the tapping blade also includes a fixing part, which is connected to the main blade. The fixing part can be connected to a cutting device, for example, it can be an electric rubber knife, a rubber tapping machine, etc. The fixing part is provided with a through hole for fixing to the cutting device. A screw is passed through the through hole to achieve a fixed connection between the tapping blade and the cutting device, so as to improve the stability between the tapping blade and the cutting device.

[0013] As an embodiment, the primary blade and the secondary blade are bent to form a second angle, and the second angle is an acute angle.

[0014] In the process of implementing the above technical solution, the main blade and the auxiliary blade are bent to form a second angle, which can prevent the auxiliary blade from contacting the cutting surface; the second angle is an acute angle, so that a blade tip is formed at the intersection of the main blade and the auxiliary blade, and the acute angle blade tip formed is sharper, which is convenient for cutting bark.

[0015] As an implementation manner, the first angle ranges from 60° to 65°.

[0016] In the process of implementing the above technical solution, the range of the first angle is 60°~65°, so that the secondary blade is an inclined surface. The debris formed after the main blade cuts the bark is discharged outside the tapping surface through the guiding effect of the secondary blade, avoiding the debris falling on the tapping surface to affect the flow of latex or cause latex overflow, affecting latex production, and at the same time avoiding the debris falling into the tapping bowl to cause latex contamination.

[0017] As an implementation manner, the second angle ranges from 72° to 75°.

[0020] In the implementation of the above technical solution, the through hole is a long hole, so that multiple screws can be fixed in the through hole to improve the stability between the tapping blade and the cutting equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1 and 5 As shown, in the first aspect, the embodiment of the present application provides a tapping blade, comprising a main blade 1 and an auxiliary blade 2 connected to each other, the main blade 1 and the auxiliary blade 2 are bent to each other, and the angle formed by the fold line 3 formed at the bending position and the horizontal line is a first angle, and the first angle is an acute angle, so that when the tapping is placed horizontally, the auxiliary blade 2 is an inclined structure relative to the main blade 1, that is, the auxiliary blade 2 is inclined and bent, so that the debris formed after the main blade 1 cuts the bark is discharged outside the tapping surface through the guiding effect of the auxiliary blade 2, thereby preventing the debris from falling on the tapping surface to affect the flow of latex or causing latex overflow, affecting the latex yield, and at the same time preventing the debris from falling into the rubber bowl to cause latex contamination.

[0031] Optionally, the rubber tapping blade is an integrally formed structure to ensure structural stability.

[0032] Optionally, the rubber tapping blade is placed horizontally, which means that the main blade 1 is placed vertically, that is, the main blade 1 is perpendicular to the horizontal plane.

[0033] Optionally, when the tapping blade is placed horizontally, the fold line 3 is an inclined diagonal line.

[0034] like Figure 4 As shown, as an embodiment, the main blade 1 is gradually widened from the connection position with the auxiliary blade 2 to the direction away from the connection position with the auxiliary blade 2, thereby reducing the contact area between the main blade 1 and the cutting surface, thereby reducing the pressure and friction of the main blade 1 on the new cutting surface, thereby reducing the probability of new severed latex ducts being blocked and increasing the glue output.

[0035] like Figure 4 As shown, optionally, the main blade 1 has a trapezoidal structure, the main cutting surface 11 is horizontally arranged, and the side opposite to the main cutting surface 11 is a bevel, so that the main blade 1 gradually widens from the connection position with the auxiliary blade 2 to the direction away from the connection position with the auxiliary blade 2.

[0036] like Figure 2 and 5 As shown, as an embodiment, the main blade 1 is provided with a main cutting surface 11, and the secondary blade 2 is provided with a secondary cutting surface 21. The main cutting surface 11 and the secondary cutting surface 21 cooperate with each other, thereby improving the cutting efficiency; and the secondary cutting surface 21 can cut off the old rubber line remaining on the cutting surface, thereby preventing the old rubber line from affecting the discharge of latex.

[0037] Optionally, the angle between the main cutting edge 11 and the secondary cutting edge 21 does not exceed 30 degrees, thereby making the rubber tapping blade sharper.

[0038] like Figure 1 and 2As shown, as an embodiment, the tapping blade also includes a fixing portion 4, which is connected to the main blade 1. The fixing portion 4 can be connected to a cutting device, such as an electric rubber knife, a rubber tapping machine, etc. A through hole 41 for fixing to the cutting device is provided on the fixing portion 4. A screw is passed through the through hole 41 to achieve a fixed connection between the tapping blade and the cutting device, thereby improving the stability between the tapping blade and the cutting device.

[0039] like Figure 3 As shown, as an embodiment, the main blade 1 and the auxiliary blade 2 are bent to form a second angle, which can prevent the auxiliary blade 2 from contacting the cutting surface; the second angle is an acute angle, so that a blade tip is formed at the intersection of the main blade 1 and the auxiliary blade 2, and the acute angle of the blade tip is sharper, which is convenient for cutting bark.

[0040] As an embodiment, the first angle is in the range of 60° to 65°, so that the auxiliary blade 2 is an inclined surface. The debris formed after the main blade 1 cuts the bark is discharged outside the tapping surface through the guiding effect of the auxiliary blade 2, thereby preventing the debris from falling on the tapping surface and affecting the flow of latex or causing latex overflow, affecting the latex yield, and at the same time preventing the debris from falling into the rubber bowl and causing latex contamination.

[0041] As an embodiment, the second angle ranges from 72° to 75°, so that the blade tip formed at the junction of the main blade 1 and the auxiliary blade 2 is sharper, which is more conducive to cutting bark and severing old glue lines.

[0042] like Figure 1 As shown, as an embodiment, the through hole 41 is an elongated hole, so that multiple screws can be fixed in the through hole 41 to improve the stability between the tapping blade and the cutting equipment.
