[0022] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 4 As shown, an oil removal machine for bicycle spoke production provided by an embodiment of the utility model comprises a workbench 1, a deoiling cylinder 3 for deoiling bicycle spoke production is rotatably mounted on the upper part of the workbench 1, a spiral transmission belt 8 is fixedly mounted inside the deoiling cylinder 3, the deoiling cylinder 3 comprises an outer cylinder 301, the outer cylinder 301 is rotatably connected to the workbench 1, an inner cylinder 302 is fixedly mounted inside the outer cylinder 301, a plurality of deoiling holes 303 are opened outside the inner cylinder 302, and a transmission gap 304 is opened between the inner cylinder 302 and the outer cylinder 301.

[0024] In order to solve the problem of uneven degreasing that may occur when a conventional degreasing machine processes a large number of or densely arranged bicycle spokes, the degreasing cylinder 3 is installed on the upper part of the workbench 1 and can rotate smoothly. A spiral conveyor belt 8 is fixedly installed inside the degreasing cylinder 3. The spiral design of the spiral conveyor belt 8 ensures that the spokes can gradually rise or fall along the spiral path when the degreasing cylinder 3 rotates. This design not only increases the contact time and area between the spokes and the degreasing medium, thereby improving the degreasing efficiency, but also ensures that each spoke can be evenly and fully degreasing even when the number of spokes is large or the arrangement is dense. The degreasing cylinder 3 is composed of an outer cylinder 301 and an inner cylinder 302. The outer cylinder 301 is firmly connected to the workbench 1 in rotation, ensuring stability during the degreasing process. The inner cylinder 302 is the key part of the degreasing cylinder 3. A number of degreasing holes 303 are cleverly opened on its outside. These degreasing holes 303 allow the degreasing medium to effectively penetrate into the surface of the spokes, thereby achieving an efficient degreasing effect. A specific transmission gap 304 is left between the inner cylinder 302 and the outer cylinder 301, and this gap provides sufficient space for the separated oil to be transmitted and discharged, thereby successfully solving the problem of uneven deoiling that may occur when a traditional deoiling machine processes a large number or dense spokes.

[0025] In this embodiment, a gear ring 4 is fixedly connected to the outside of one side of the outer cylinder 301, and a limit ring 7 is fixedly connected to the outside of the other side of the outer cylinder 301. The inner sides of the gear ring 4 and the limit ring 7 are respectively rotatably fitted to the outer sides of the two sides of the workbench 1. A motor 2 is fixedly installed on one side of the workbench 1, and a gear 5 is fixedly installed on the output end of the motor 2, and the gear 5 is meshed with the gear ring 4.

[0026] In order to drive the de-oiling cylinder 3 to rotate efficiently and stably, a gear ring 4 is fixedly connected to the outside of one side of the outer cylinder 301 of the de-oiling machine. The design of the gear ring 4 is not only sturdy and durable, but also accurately aligned with the rotation axis of the de-oiling cylinder 3, ensuring the accuracy of the transmission. On the other side of the outer cylinder 301, we fixedly connected a limit ring 7. The function of the limit ring 7 is to prevent the de-oiling cylinder 3 from deflecting or shaking during the rotation process, thereby ensuring the stability of the transmission.

[0027] The inner sides of the gear ring 4 and the limit ring 7 are precisely machined to ensure that they can fit tightly with the outer sides of the workbench 1, which can not only reduce friction and wear, but also improve the efficiency of transmission. On one side of the workbench 1, we fixedly installed a motor 2, and a gear 5 is fixedly installed at the output end of the motor 2. The gear 5 and the gear ring 4 are meshed.

[0028] When the motor 2 is started, the gear 5 drives the gear ring 4 to rotate, and the gear ring 4 is fixedly connected to the outer cylinder 301, so the outer cylinder 301 will also rotate. Due to the meshing design of the gear ring 4 and the gear 5, this rotation is smooth and continuous, which can ensure that the de-oiling cylinder 3 maintains a stable speed and direction during rotation. At the same time, the presence of the limit ring 7 also ensures the stability of the de-oiling cylinder 3 during rotation, avoiding transmission failure due to vibration or impact. In this way, the motor 2 can efficiently drive the de-oiling cylinder 3 to rotate, providing a stable power source for the de-oiling process of the spokes. This not only improves the de-oiling efficiency, but also reduces the failure rate of the equipment, providing reliable technical support for the production of bicycle spokes.

[0029] In this embodiment, the outer cylinder 301 includes a cylinder body 3011 , and a magnetic cylinder 3012 is embedded in the cylinder body 3011 . The magnetic cylinder 3012 absorbs oil from the bicycle spokes transmitted in the inner cylinder 302 .

[0030] The outer cylinder 301 is mainly composed of a strong and durable cylinder body 3011, and a magnetic cylinder 3012 is embedded in the cylinder body 3011. The introduction of this magnetic cylinder 3012 greatly enhances the adsorption capacity of the de-oiling machine to oil stains.

[0031] The magnetic cylinder 3012 is made of high-performance magnetic material and has a strong magnetic attraction. When the bicycle spokes in the inner cylinder 302 are driven by the spiral conveyor belt 8 and are transmitted along the spiral path, the magnetic cylinder 3012 will strongly absorb the oil stains attached to the surface. The tiny particles in the oil stains are quickly attracted to the magnetic cylinder 3012 under the action of the magnetic force, thereby achieving efficient degreasing of the spokes.

[0032] The design of the magnetic tube 3012 not only improves the degreasing efficiency, but also ensures the uniformity of the degreasing process. Since the magnetic tube 3012 covers the outside of the inner tube 302, its adsorption range is wide, which can ensure that each spoke can be fully adsorbed and treated with oil during the transmission process. At the same time, the adsorption force of the magnetic tube 3012 is evenly distributed, avoiding deformation or damage of the spokes due to excessive local adsorption.

[0033] In this embodiment, the de-oiling machine further includes a spray assembly 6, which includes a support pipe 603. Two support pipes 603 are provided, and the two support pipes 603 are respectively fixed on one side of the workbench 1. An input pipe 605 for connecting to a de-oiling agent supply source is respectively fixedly connected to the bottom of each support pipe 603. A connecting rod 604 is fixedly connected between the two input pipes 605. The inner sides of the two support pipes 603 are respectively fixedly connected to the same transmission pipe 601, and a plurality of spray heads 602 are fixedly installed at the lower part of the transmission pipe 601.

[0034] An input pipe 605 is installed at the bottom of each support pipe 603. The main function of these input pipes 605 is to be connected to the deoiling agent supply source to ensure that a continuous supply of deoiling agent can be smoothly delivered to the spray assembly 6. The two input pipes 605 are cleverly connected by a connecting rod 604, which not only enhances the structural stability of the entire spray assembly 6, but also makes the delivery of the deoiling agent more balanced and smooth.

[0035] The inner sides of the two support tubes 603 are connected to the same transmission tube 601. The degreasing agent is evenly distributed to each part that needs to be sprayed. At the bottom of the transmission tube 601, a number of spray heads 602 are fixedly installed. These spray heads 602 are like fine raindrops, spraying the degreasing agent evenly in the form of mist on the bicycle spokes.

[0036] When the work starts, the spray assembly 6 starts synchronously. The degreasing agent enters the transmission pipe 601 through the input pipe 605, and is then sprayed out by the spray head 602 in the form of mist, covering the surface of the spokes. This spraying method not only allows the degreasing agent to evenly cover the spokes, but also avoids waste caused by excessive use. At the same time, the mist degreasing agent can more easily penetrate into the tiny gaps of the spokes, removing the hidden oil stains.

[0037] By adding the spray assembly 6, the deoiling effect of the deoiling machine is further improved, providing a more comprehensive and efficient deoiling solution for the production of bicycle spokes.

[0038] The working principle of this utility model:

[0039] When in use, in order to solve the problem of uneven degreasing that may occur when a conventional degreasing machine processes a large number of or densely arranged bicycle spokes, the degreasing cylinder 3 is installed on the upper part of the workbench 1 and can rotate smoothly. A spiral conveyor belt 8 is fixedly installed inside the degreasing cylinder 3. The spiral design of the spiral conveyor belt 8 ensures that the spokes can gradually rise or fall along the spiral path when the degreasing cylinder 3 rotates. This design not only increases the contact time and area between the spokes and the degreasing medium, thereby improving the degreasing efficiency, but also ensures that even when the number of spokes is large or the arrangement is dense, each spoke can be evenly and fully degreasing. The degreasing cylinder 3 consists of an outer cylinder 301 and an inner cylinder 302. The outer cylinder 301 is firmly connected to the workbench 1 in rotation, ensuring stability during the degreasing process. The inner cylinder 302 is the key part of the degreasing cylinder 3. A number of degreasing holes 303 are cleverly opened on its outside. These degreasing holes 303 allow the degreasing medium to effectively penetrate into the surface of the spokes, thereby achieving an efficient degreasing effect. A specific transmission gap 304 is left between the inner cylinder 302 and the outer cylinder 301, and this gap provides sufficient space for the separated oil to be transmitted and discharged, thereby successfully solving the problem of uneven deoiling that may occur when a traditional deoiling machine processes a large number or dense spokes.
