Description

Technical Field

[0001] This utility model relates to the field of tape-making machines, specifically to a short-distance tape-making machine with a horn-shaped design. Background Technology

[0002] The main function of a wrapping machine is to wrap the insulated core wires of electrical wires, power cables, control cables, optical cables, etc. It wraps the wrapping tape (such as mica tape, cotton paper tape, aluminum foil, polyester film, etc.) around a horn-shaped piece. The horn-shaped piece rotates on the outside of the core wire, thus wrapping the tape around the core wire to achieve insulation and protection.

[0003] The outward extension of the horn-shaped component in existing tape wrapping machines is relatively long, resulting in a relatively large weight and poor dynamic balance during high-speed rotation. When the horn-shaped component extends a long distance, its mass distribution is relatively dispersed, increasing the offset of the center of gravity from the axis of rotation. During high-speed rotation, this offset generates significant centrifugal force, causing equipment vibration. This not only affects the tape wrapping machine's working accuracy and stability but also increases the failure rate and impacts production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a short-distance horn for a tape wrapping machine. This horn reduces the weight of the horn by using smaller horn pieces, improves the dynamic balance performance of the horn pieces during high-speed rotation, reduces the degree of center of gravity offset of the horn pieces, thereby reducing the vibration amplitude of the horn pieces during rotation and improving the working accuracy and stability of the tape wrapping machine.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A short-distance U-shaped wrapping machine includes a U-shaped component, a connector, and a main shaft. The U-shaped component and the main shaft are coaxially fixed on the left and right sides of the connector. The U-shaped component is U-shaped and includes two horizontally arranged guide rods. The distance between the guide rods is less than the height of the connector. The connector and the guide rods are provided with a number of guide wheels for wrapping tape winding.

[0007] In the above technical solution, preferably, the connector is rotatably provided with a driving wheel, a driven wheel and a transmission mechanism. When the main shaft rotates, the driving wheel is driven to rotate through the transmission mechanism, and the strap is clamped between the driving wheel and the driven wheel.

[0008] In the above technical solution, preferably, the transmission mechanism includes a first gear, a second gear, a third gear, and a fourth gear. The first gear and the second gear are two bevel gears that mesh with each other. The first gear is coaxially fixed on the main shaft. The third gear and the second gear are coaxially fixed and rotatably disposed in the connecting member. The fourth gear is coaxially fixed with the driving wheel and meshes with the third gear.

[0009] In the above technical solution, preferably, a first guide wheel is rotatably disposed inside the connector, and a second guide wheel and a third guide wheel are rotatably disposed inside the guide rod, with the second guide wheel near the right end of the guide rod and the third guide wheel located at the left end of the guide rod.

[0010] In the above technical solution, preferably, a pulley is coaxially fixed on the main shaft.

[0011] In the above technical solution, preferably, the main shaft is provided with a first channel for the core wire to pass through and a second channel for the wrapping tape to pass through. The second channel is connected to the lower side of the drive shaft inside the connector, and a through hole for the core wire to pass through is opened in the middle position of the horn piece.

[0012] In the above technical solution, preferably, the surfaces of the driving wheel, driven wheel, first guide wheel, second guide wheel and third guide wheel are all provided with a rubber coating layer.

[0013] Compared with the prior art, this utility model has the following advantages and effects:

[0014] This invention involves rotatably mounting a main shaft inside a tape wrapping machine. One end of the tape is sequentially wound around several guide wheels within a connector and guide rods, and finally fixed to the core wire. A drive device drives the main shaft, connector, and horn-shaped component to rotate as a whole. As the core wire moves along the rotation axis of the horn-shaped component, the tape wraps around the core wire, achieving the tape wrapping operation. Because the horn-shaped component in this invention is U-shaped, with two horizontally positioned guide rods and a small gap between them, compared to existing horn-shaped components where the guide rods extend obliquely outwards before horizontally extending, resulting in a larger gap between the two guide rods, this horn-shaped component is smaller in size, reducing its weight. This improves the dynamic balance performance of the horn-shaped component during high-speed rotation, reduces the degree of center-of-gravity shift, thus reducing the vibration amplitude of the horn-shaped component during rotation. This improves the working accuracy and stability of the tape wrapping machine, reduces the equipment failure rate, and ultimately increases production efficiency. Attached Figure Description

[0018] Among them, there are: horn-shaped part 1, guide rod 11, guide wheel 12, first guide wheel 13, second guide wheel 14, third guide wheel 15, through hole 16, connecting part 2, driving wheel 21, driven wheel 22, transmission mechanism 23, first gear 24, second gear 25, third gear 26, fourth gear 27, main shaft 3, pulley 31, first channel 32, second channel 33, and wrapping strap 4. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] See Figures 1-3 This embodiment provides a short-distance U-shaped strapping machine, comprising a U-shaped component 1, a connecting component 2, and a main shaft 3. The U-shaped component 1 and the main shaft 3 are coaxially fixed on the left and right sides of the connecting component 2. The U-shaped component 1 includes two horizontally arranged guide rods 11, the distance between which is less than the height of the connecting component 2. The connecting component 2 and the guide rods 11 are provided with a plurality of guide wheels 12 for the strapping 4 to be wound.

[0021] This invention rotatably mounts the main shaft 3 inside the wrapping machine. One end of the wrapping tape 4 is sequentially wound around several guide wheels 12 within the connector 2 and guide rods 11 and finally fixed to the core wire. A drive device drives the main shaft 3, connector 2, and the horn-shaped component 1 to rotate as a whole. Thus, when the core wire moves along the rotation axis of the horn-shaped component 1, the wrapping tape 4 can wrap around the core wire, achieving the wrapping operation. Because the horn-shaped component 1 in this invention is U-shaped, and the two guide rods 11 are horizontally positioned with a small gap between them, compared to existing horn-shaped components where the guide rods 11 extend obliquely outwards before horizontally extending, resulting in a larger gap between the two guide rods 11, the horn-shaped component 1 is smaller in size, reducing its weight. This improves the dynamic balance performance of the horn-shaped component 1 during high-speed rotation, reduces the degree of center of gravity shift, thus reducing the vibration amplitude of the horn-shaped component 1 during rotation, improving the working accuracy and stability of the wrapping machine, reducing the equipment failure rate, and thus increasing production efficiency.

[0022] See Figure 1 A pulley 31 is coaxially fixed on the main shaft 3, which facilitates connection with the drive motor via a belt and improves the convenience of driving the main shaft 3 to rotate.

[0023] See Figure 2 , Figure 3 The connecting member 2 is rotatably provided with a driving wheel 21, a driven wheel 22 and a transmission mechanism 23. When the main shaft 3 rotates, the driving wheel 21 is driven to rotate through the transmission mechanism 23, and the strap 4 is clamped between the driving wheel 21 and the driven wheel 22.

[0024] The tape 4 is held between the drive wheel 21 and the driven wheel 22, and the rotation of the main shaft 3 drives the drive wheel 21 to rotate to achieve active tape feeding. This can improve the stability of tape feeding when the tape machine is working, reduce the risk of the tape 4 getting stuck in the connector 2 and the main shaft 3, and reduce the failure rate of the equipment.

[0025] See Figure 2 The transmission mechanism 23 includes a first gear 24, a second gear 25, a third gear 26, and a fourth gear 27. The first gear 24 and the second gear 25 are two bevel gears that mesh with each other. The first gear 24 is coaxially fixed on the main shaft 3. The third gear 26 and the second gear 25 are coaxially fixed and rotatably disposed in the connecting member 2. The fourth gear 27 is coaxially fixed with the driving wheel 21 and meshes with the third gear 26.

[0026] Through the transmission action between the first gear 24, the second gear 25, the third gear 26 and the fourth gear 27, the drive wheel 21 can rotate simultaneously when the main shaft 3 rotates. This avoids the need to set up a separate drive device (such as a motor) in the connecting part 2 to drive the drive wheel 21 to rotate. This avoids the situation where it is difficult to connect the power supply line to the drive device when the connecting part 2 rotates, which would cause the drive device to have difficulty supplying power. At the same time, it reduces the working energy consumption of the tape wrapping machine.

[0027] In this invention, the front and rear sides of the connector 2 are symmetrically provided with a second gear 25, a third gear 26, and a fourth gear 27. The two second gears 25 mesh with the first gear 24 at the same time, thereby simultaneously applying driving force to the front and rear ends of the drive wheel 21 to make the drive wheel 21 rotate, improving the stability of the rotation of the drive wheel 21. It also makes the weight of the connector 2 symmetrical at the front and rear, so that the center of gravity of the connector 2 is located on its rotation axis, improving the stability of the connector 2 when rotating at high speed.

[0028] See Figure 3 The connector 2 is rotatably provided with a first guide wheel 13, and the guide rod 11 is rotatably provided with a second guide wheel 14 and a third guide wheel 15. The second guide wheel 14 is close to the right end of the guide rod 11, and the third guide wheel 15 is located at the left end of the guide rod 11.

[0029] After the strapping tape 4 enters the connector 2, it is first guided by the first guide wheel 13 to facilitate the insertion of the strapping tape 4 between the driving wheel 21 and the driven wheel 22. After the strapping tape 4 passes through the driving wheel 21 and the driven wheel 22, it is first placed on the lower side of the second guide wheel 14 and then on the upper side of the third guide wheel 15. Compared with the existing method in the horn-shaped connector 1 where the strapping tape 4 is placed on the outside of the two guide wheels 12, this embodiment allows the strapping tape 4 to be located inside the guide rod 11 and staggered on the guide wheels 12. This reduces the air resistance experienced by the strapping tape 4 when the horn-shaped connector 1 rotates at high speed, reduces the probability of the strapping tape 4 separating from the guide wheel 12 due to air resistance and centrifugal force, and tightens the strapping tape 4, thereby ensuring the stability and uniformity of the strapping tape 4 wound on the core wire.

[0030] See Figure 3 The main shaft 3 is provided with a first channel 32 for the core wire to pass through and a second channel 33 for the wrapping tape 4 to pass through. The second channel 33 is connected to the lower side of the drive shaft in the connector 2. A through hole 16 for the core wire to pass through is opened in the middle position of the horn piece 1.

[0031] The core wire passes sequentially through the first channel 32 and the through hole 16, aligning the core wire with the rotation axis of the horn-shaped component 1. This allows the horn-shaped component 1 to evenly wind the strapping 4 around the core wire when it rotates. The strapping 4 is pulled from the strapping roll, passes through the second channel 33, then between the drive wheel 21 and the driven wheel 22, and then wound around the horn-shaped component 1, finally securing it to the core wire. In actual operation, because the strapping 4 is relatively soft and difficult to thread, one end of the strapping 4 is tied to a strip of aluminum foil. The traction of the aluminum foil improves the ease of threading the strapping 4. The strapping roll is coaxially mounted inside the strapping machine and rotates simultaneously with the main shaft 3, ensuring the stability of the strap feeding.

[0032] The surfaces of the driving wheel 21, driven wheel 22, first guide wheel 13, second guide wheel 14 and third guide wheel 15 are all coated with a rubber layer.

[0033] The rubber coating increases the friction between the tape 4 and the drive wheel 21, driven wheel 22, first guide wheel 13, second guide wheel 14, and third guide wheel 15, reducing the probability of tape 4 wear due to sliding friction. Simultaneously, the rubber coating has a certain shock-absorbing effect, reducing the risk of tape 4 breaking due to excessive instantaneous stress during tape wrapping machine operation. The rubber coating can be made of rubber.

[0034] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
