Description

Technical Field

[0001] The invention relates to the technical field of wire stripping, and in particular to a dust absorbing block with a high-efficiency dust absorbing flow channel design. Background Art

[0002] At present, the dust suction equipment equipped on some wire stripping devices usually only has one dust suction pipe or air blowing pipe, and this one-way air blowing device does not have a very good dust suction effect on the wire stripping device. For example, Chinese patent CN202021877589.0 discloses a stripping machine suitable for cables, which includes a base, a connecting seat 1, a lower guide wheel 1, an upper guide wheel 1, a guide sleeve, a guide seat, a guide hole, an inner groove, a dust suction pipe, a dust collector, a stripping knife groove, an upper guide wheel 2, a lower guide wheel 2, a motor 1, a connecting seat 2 and a stripping device; the dust collector provided in the mechanism can suck out dust and debris on the surface of the cable through the dust suction pipe and the inner groove, thereby avoiding dust and debris from entering the cable during stripping and affecting the subsequent use quality. However, the dust suction effect of the mechanism can be further improved. Some places inside it where air cannot be blown, such as the back of the tool, will retain some debris and dust, which will accumulate over a long period of time and affect the efficiency of wire stripping and the life of the tool. Summary of the invention

[0003] In view of this, the present invention provides a dust collecting block with a high-efficiency dust collecting flow channel design to solve the above-mentioned problem.

[0019] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0020] Please also read Figures 1 to 5 The dust collecting block with efficient dust collecting flow channel design is arranged at one end of a wire stripping device 10, and the dust collecting block with efficient dust collecting flow channel design includes a block body 20, a first air inlet chamber 30 opened inside the block body 20, a second air inlet chamber 40 opened on one side of the first air inlet chamber 30, and a dust removal chamber 50 opened on one side of the second air inlet chamber 40. It can be imagined that the dust collecting block with efficient dust collecting flow channel design also includes some other functional modules, such as screw modules, air supply modules, etc., which are technologies well known to those skilled in the art and will not be described one by one here.

[0021] It should be noted that the three cutters 11 of the wire stripping device 10 are located at the center of the dust removal chamber 50 to ensure that the debris and dust stripped by the cutters 11 can be retained in the dust removal chamber 50 .

[0022] A wire entry hole 21 is formed on one side of the block body 20 facing the first air inlet chamber 30 . The wire entry hole 21 is used to pass the wire stripping device 10 to ensure that the wire can be stripped in the dust removal chamber 50 .

[0023] The block body 20 is provided with a wire outlet hole 22 coaxial with the wire inlet hole 21 on one side thereof, and the wire outlet hole 22 is used to send out the wires after stripping. The three cutters 11 of the wire stripping device 10 extend from the wire inlet hole 21 into the dust removal chamber 50, and the stripped wires pass through the wire outlet hole 22.

[0024] A dust outlet 23 is formed on one side of the block body 20 relative to the second air inlet chamber 40 , and the dust outlet 23 is connected to a pipe (not shown) to discharge the peeled debris and dust.

[0025] Two air pipe joints 24 are provided on one side of the block body 20 , and the two air pipe joints 24 are connected to an external air supply module, so that a blowing effect is achieved inside the block.

[0026] The first air inlet chamber 30 is in a hollow annular shape, and the axis of the first air inlet chamber 30 coincides with the axis of the inlet hole 21. A first air inlet hole 31 is provided on one side of the first air inlet chamber 30 facing the air pipe connector 24, and the first air inlet hole 31 is connected to one of the air pipe connectors 24, so that external air is introduced into the first air inlet chamber 30.

[0027] The first air inlet chamber 30 is provided with three first blowing air channels 32 on one side facing the dust removal chamber 50. The three first blowing air channels 32 are distributed in an isosceles triangle. The three first blowing air channels 32 are arranged obliquely and the air outlets are all oriented toward the center point of the dust removal chamber 50, so that the gas in the first air inlet chamber 30 can be blown onto the three cutting tools 11. It can be imagined that the front of the cutting tool 11 is cleaned by the air blown out from the second air inlet chamber 40, but the air circulation on the back of the cutting tool 11 is slow, and the debris and dust on the back of the cutting tool 11 cannot be effectively blown off. Since the three first blowing air channels 32 are arranged obliquely, the air blown out can be blown onto the back of the three cutting tools 11, and then the debris and dust remaining on the cutting tools 11 can be blown off, thereby improving the dust suction effect of the block, thereby improving the wire stripping efficiency and the life of the cutting tool.

[0028] The second air inlet chamber 40 is in a hollow annular shape, and the axis of the second air inlet chamber 40 and the axis of the first air inlet chamber 30 are located on the same horizontal plane and are perpendicular to each other. A second air inlet hole 41 is provided on the side of the second air inlet chamber 40 facing the air pipe joint 24, and the second air inlet hole 41 is connected to one of the air pipe joints 24, so that the external air is connected to the second air inlet chamber 40. Three second blowing air channels 42 are provided on the side of the second air inlet chamber 40 facing the dust removal chamber 50, and the three second blowing air channels 42 are distributed in an isosceles triangle.

[0029] The dust removal chamber 50 is located between the second air inlet chamber 40 and the dust outlet hole 23. The dust removal chamber 50 has a concave arc surface on one side close to the second air inlet chamber 40. When the air inside the dust removal chamber 50 is blown, the resistance of the arc surface will be small, so that the air flow at this place will be smoother, thereby facilitating the discharge of debris and dust. And because the three second blowing air channels 42 are arranged relative to the dust outlet hole 23, the air blown out of the second blowing air channels 42 can be directly blown to the dust outlet hole 23 and pass through the tool 11. The airflow will not change direction, so that the dust blown off is directly delivered to the dust outlet hole 23, avoiding dust splashing to various places in the dust removal chamber 50, and facilitating the discharge of debris and dust.

[0030] Compared with the prior art, the dust suction block with a high-efficiency dust suction flow channel design provided by the present invention can clean the back of the tool 11 through the three obliquely arranged first blowing flow channels 32, and then discharge the debris and dust scattered in the dust removal chamber 50 from the dust outlet hole 23 through the three second blowing flow channels 42, thereby greatly improving the dust suction effect of the block, thereby improving the wire stripping efficiency and tool life of the wire stripping device.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
