Abstract
Description
Technical Field
[0001] This invention relates to the field of rubber processing technology, and in particular to a centrifugal edge removal machine. Background Technology
[0002] In order to pursue high utilization rate of vulcanizing equipment and improve productivity, most existing rubber production molds are multi-cavity molds. However, due to the characteristics of rubber, the rubber waste edges formed during the production process can easily stick the products together. Therefore, it is necessary to add a waste edge removal process.
[0003] Currently, rubber edge-removing machines are commonly used to remove excess circumferential edges from rubber products. These machines operate on aerodynamic principles, using a high-speed rotating disc inside a cylinder to drive the rubber product at high speed. This centrifugal force causes the rubber product to impact the inner wall of the cylinder, separating the weaker edges from the product and achieving the effect of removing burrs. There are several types of rubber edge-removing machines. For example, Chinese utility model patent CN211105118U discloses a rubber edge-removing machine. During operation, the rotating disc drives the rubber product to rotate at high speed, causing it to continuously impact a first convex strip, a second convex strip, and a stirring component. The inclusion of these components increases the impact probability, improving the separation speed between the rubber product and the burrs, thus increasing the edge-removing efficiency.
[0004] In the aforementioned rubber stripping machine, the open top of the cylinder results in a large space for the rubber products to move during the stripping process. On the one hand, this reduces the probability of collisions, leading to low stripping efficiency. On the other hand, under high-speed rotation, rubber products are prone to splashing out from the top, posing a safety hazard to surrounding workers. Furthermore, the simple structure and single function of the rotating disc in this machine result in minimal difference in the speed at which the rubber products detach from the disc due to centrifugal force. This leads to a low probability of collisions between the rubber products after they leave the disc, further hindering the stripping process. Efficiency; In addition, during the separation process, the rubber products are affected by centrifugal force and gravity. Most of the rubber products eventually stop on the inner wall of the cylinder and are no longer affected by centrifugal force to collide. Due to the small number of collisions, the waste edges on the rubber products are difficult to detach automatically, which affects the separation effect. Moreover, the rubber products are concentrated in the lower part of the cylinder, and the internal space of the cylinder cannot be fully utilized for collision. In addition, during the contact between the agitator and the rubber products, the agitator is prone to damaging the rubber products due to the relatively high speed of movement between the two, which ultimately results in some defective products mixed in with the separated products.
[0005] Therefore, it is necessary to improve the existing centrifugal edge-removing machine. Summary of the Invention

Detailed Implementation
[0045] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0046] First Embodiment
[0047] like Figures 1-4 As shown, the centrifugal edge-removing machine of the first embodiment includes:
[0048] Fixture 1;
[0049] The splitting cylinder 2 is mounted vertically on the fixed frame 1. The bottom of the side wall of the splitting cylinder 2 is provided with a discharge port 21, and the discharge port 21 is provided with a discharge valve 3.
[0050] Centrifuge disc 4 is sealed to the bottom of splitting cylinder 2 and is connected to a rotating component 5 that drives itself to rotate around the axis of splitting cylinder 2.
[0051] The material blocking assembly 6 includes a material blocking component 61 and a driving component 62 that drives the material blocking component 61 to move between the first station and the second station. The material blocking component 61 at the first station is sealed to the circumferential inner wall of the splitting cylinder 2 and is located between the splitting cylinder 2 and the discharge port 21. The material blocking component 61 at the second station is enclosed by the inner wall of the splitting cylinder 2 to form a discharge port.
[0052] The centrifugal edge trimming machine of this embodiment is mainly used to separate the rubber product body and the waste edges on the outer periphery of the rubber product. In the edge trimming machine, the fixed frame 1 is mainly a cabinet structure, including a horizontal base plate 11. The bottom of the base plate 11 is provided with support legs 16 for supporting the centrifugal edge trimming machine. A vertical back plate 14 and end plates 13 located at both ends of the back plate 14 are provided above the base plate 11. The horizontal base plate 11 is fixed on the top of the back plate 14 and the two end plates 13. The side of the two end plates 13 away from the back plate 14 is rotatably connected to the cabinet door 15 through hinges 17. The splitting cylinder 2 is fixed between the base plate 11, the top plate 12, the end plates 13, the back plate 14 and the cabinet door 15.
[0053] A locking assembly is provided between the two cabinet doors 15 to lock them together. In the locked state, the cabinet door 15, together with the bottom plate 11, top plate 12, end plate 13, and back plate 14, forms an enclosing cavity that protects the splitting cylinder 2. The locking assembly includes a locking sleeve 151 integrally formed on the side of the cabinet door 15 away from the back plate 14 and extending horizontally. A bolt 152 passes between the locking sleeves 151 of the two cabinet doors 15, and a nut 153 is threaded onto the bolt 152. The two cabinet doors 15 are locked together by the connection of the bolt 152 and the nut 153, protecting the splitting cylinder 2. By separating the bolt 152 and the nut 153, the cabinet door 15 can be opened to observe the inside of the fixing frame 1.
[0054] The top plate 12 is fitted with the top of the splitting cylinder 2 with a clearance. The top plate 12 is provided with a feeding port 121, which is located directly above the splitting cylinder 2. The inner diameter of the feeding port 121 is smaller than the inner diameter of the splitting cylinder 2, so that the operator can easily put the rubber with the edge splitting treatment into the splitting cylinder 2 through the feeding port 121. The top plate 12 is provided with a cover plate 18 that is rotatably connected to it. The cover plate 18 is used to cover the feeding port 121 to prevent the rubber in the splitting cylinder 2 from falling off the top of the splitting cylinder 2. For easy observation, the cover plate 18 is a glass plate.
[0055] The splitting cylinder 2 is a cylindrical cylinder. A discharge port 21 is provided on the lower part of the circumferential side wall of the splitting cylinder 2. A downwardly inclined discharge pipe 26 is fixedly provided on the discharge port 21. A discharge valve 3 is provided inside the discharge pipe 26. A discharge port 131 is provided on one of the end plates 13. The circumferential inner wall of the discharge port 131 is fixedly connected to the circumferential outer edge of the discharge pipe 26. The discharge valve 3 includes a discharge plate 31, a connecting rod 32, and a discharge cylinder 33. The discharge plate 31 is used to seal the discharge port 21. The top of the discharge plate 31 rotates inside the discharge pipe 26. Its rotation axis extends along the width direction of the discharge pipe 26. The cylinder of the discharge cylinder 33 is fixed on the inner top wall of the discharge pipe 26. The piston rod is hinged to the discharge plate 31 through the connecting rod 32.
[0056] The rotating assembly 5 includes a mounting bracket 515 fixed to the outer wall of the splitting cylinder 2. A rotating motor 511 is arranged below the mounting bracket 515. The output end of the rotating motor 511 is coaxially connected to a drive wheel 512. The drive wheel 512 is driven by a driven wheel 514 through a synchronous belt 513. The driven wheel 514 is coaxially connected to the centrifugal disc 4. A rotating bearing 516 is arranged below both the drive wheel 512 and the driven wheel 514. The outer rings of the two rotating bearings 516 are fixed above the base plate 11, and the inner rings are coaxially connected to the drive wheel 512 and the driven wheel 514, respectively.
[0057] When the device is in use, in the material blocking assembly 6, the drive assembly 62 drives the material blocking component 61 to move to the second working position, rotates the cover plate 18 to open the feeding port 121, and puts the rubber product to be de-edge processed into the splitting cylinder 2 through the feeding port 121. The rubber product enters the splitting cylinder 2 through the discharge port and falls onto the centrifugal disc 4. Then the cover plate 18 is closed, and the drive assembly 62 adjusts the material blocking component 61 to the first working position, so that the material blocking component 61 is sealed to the circumferential inner wall of the splitting cylinder 2, compressing the movable impact space of the gap rubber product.
[0058] Then, the rotary motor 511 is started, which drives the drive wheel 512 to rotate. The drive wheel 512 drives the driven wheel 514 to rotate under the support of the rotary bearing 516 through the synchronous belt 513, which in turn drives the centrifugal disc 4 above it to rotate, giving the rubber products on the centrifugal disc 4 a rotational speed. This causes the rubber products to collide in the splitting cylinder 2 under the influence of centrifugal force, and the waste edges on the rubber products are removed through the collision.
[0059] After the waste edge is separated, the rotary motor 511 is turned off and the discharge cylinder 33 is started. The piston rod pulls the connecting rod 32, which in turn drives the discharge plate 31 to rotate upward, so that the rubber products and the separated waste edge in the splitting cylinder 2 can be discharged through the discharge pipe 26.
[0060] During the separation process, the baffle 61 in the baffle assembly 6 is sealed to the circumferential inner wall of the splitting cylinder 2, and the baffle 61 is located between the top of the splitting cylinder 2 and the discharge port 21. This reduces the space available for the compressed rubber products to move, thereby increasing the probability of collisions between the rubber products and the splitting cylinder 2, thus increasing the frequency of collisions, improving the effect of separating waste edges from the rubber products, shortening the waste edge processing time, and improving work efficiency. Moreover, the baffle 61 can also prevent the rubber products from overflowing from the top of the splitting cylinder 2 during the waste edge processing, avoiding splashing to the outside and posing a safety hazard to surrounding workers, thus ensuring safe processing.
[0061] A further improvement is that the baffle 61 includes a horizontal baffle plate, the drive assembly 62 drives the baffle plate to translate, and the splitting cylinder 2 is provided with an arc-shaped opening 22 for the baffle plate to pass through; at least two baffle assemblies 6 are provided and are distributed at intervals along the axial direction of the splitting cylinder 2.
[0062] Specifically, in this invention, the driving component 62 is a driving cylinder, the cylinder barrel of which is horizontally arranged and fixed on one of the end plates 13, the piston rod is fixedly connected to the baffle plate, the baffle plate is horizontally arranged, the arc-shaped opening 22 is a semi-circular opening, and its top inner wall and bottom inner wall are respectively sealed to the top surface and bottom surface of the baffle plate.
[0063] With the above structure, the horizontal baffle is moved horizontally by the drive cylinder and moves between the first and second work stations, which facilitates compression and reduces the impact space of the rubber products. Moreover, when both baffles move to the first work station, the inner cavity of the splitting cylinder 2 can be divided into three parts, which are the feeding cavity, the transition cavity and the separation cavity from top to bottom. During the edge-removal process of rubber products in the separation chamber, rubber products are fed into the chamber. The upper baffle moves to the second station, contacting the lower baffle. The upper baffle then moves to the first station, and more rubber products are fed into the upper baffle. Thus, there are three batches of rubber products in the splitting cylinder 2. After the rubber products in the bottom separation chamber are edge-removed, they are discharged from the discharge port 21. The lower baffle moves to the second station, allowing the rubber products in the transition chamber to enter the separation chamber. Then, the lower baffle moves to the first station, and the upper baffle moves to the second station, allowing the rubber products in the feed chamber to enter the transition chamber before returning to the first station for the next batch of rubber products. This facilitates orderly, batch-by-batch edge-removal of rubber products, improving work efficiency, further reducing the movement space of the rubber products, increasing the probability of collision, improving the edge-removal effect, and enhancing product quality.
[0064] Second Embodiment
[0065] like Figures 5-11 As shown, the centrifugal edge removal machine of the second embodiment is based on the first embodiment, except that the centrifugal disk 4 includes an inner disk 41, a clamping disk 42 and an outer ring disk 43 that are coaxial and smoothly connected on their top surfaces. The clamping disk 42 is sealed and fitted between the inner disk 41 and the outer ring disk 43. The rotating component 5 drives the inner disk 41, the clamping disk 42 and the outer ring disk 43 to rotate around the axis of the centrifugal disk 4, and there is a speed difference between the clamping disk 42 and the inner disk 41 and the outer ring disk 43.
[0066] Compared to the integrated structure of the centrifugal disc 4 in the first embodiment, the centrifugal disc 4 in this embodiment adopts a separate structure consisting of an inner disc 41, a clamping disc 42, and an outer disc 43. The rotating component 5 drives the three components to rotate, so that there is a speed difference between the clamping disc 42 and the inner disc 41 and the outer disc 43. The rubber products detached from the clamping disc 42 and the rubber products detached from the inner disc 41 and the outer disc 43 move away from the axis of the centrifugal disc 4 at different speeds. This makes it easy for the rubber products to collide with each other due to the speed difference, increasing the probability of collision between the rubber products, improving the waste edge separation effect, and increasing the flash edge separation efficiency.
[0067] To facilitate stable control of the inner disc 41, the clamping disc 42, and the outer disc 43, in this embodiment, the inner disc 41 and the outer disc 43 are integrally connected by a chassis 44, which is located below the inner disc 41 and the outer disc 43. The rotating assembly 5 includes a first rotating unit 51 and a second rotating unit 52. The first rotating unit 51 is driven to the chassis 44, and the second rotating unit 52 is driven to the clamping disc 42. The second rotating unit 52 includes a rotating component 521 that is coaxial with the clamping disc 42 and magnetically attracted to it, a rotating wheel 523 that abuts against the rotating component 521 and whose axis is perpendicular to the axis of the clamping disc 42, a rotating shaft 524 that slides axially with the rotating wheel 523 and is radially fixed, a rotating device 525 that drives the rotating shaft 524 to rotate in a directional and constant speed, and a translation unit 526 that drives the rotating wheel 523 to slide axially along the rotating shaft 524.
[0068] Specifically, such as Figure 7 , Figures 9-11 As shown, the inner disc 41 and the outer ring disc 43 are integrally connected by the base plate 44 to form an annular groove, which ensures the structural strength of the connection between the inner disc 41 and the outer ring disc 43, so that the first rotating unit 51 can drive the inner disc 41 and the outer ring disc 43 to rotate synchronously and stably. The clamping disc 42 is adapted to the annular groove. The outer circumferential edge of the inner disc 41 and the inner circumferential wall of the outer ring disc 43 are provided with annular grooves 45 with coaxial center lines. The outer circumferential edge and the inner circumferential wall of the clamping disc 42 are provided with convex rings 422 with coaxial center lines. The convex rings 422 are adapted to the annular grooves 45 to position the axial position of the clamping disc 42 and prevent the clamping disc 42 from sliding axially.
[0069] The bottom center of the chassis 44 is concave and is equipped with a connecting bearing 522. The rotating component 521 is a rotating cylinder with a convex center, which is adapted to the chassis 44. The chassis 44 and the rotating component 521 are connected by the connecting bearing 522. The outer ring of the connecting bearing 522 is fixedly connected to the chassis 44, and the inner ring is fixedly connected to the rotating component 521. The clamping ring disk 42 and the rotating component 521 are magnetically attracted to each other. The second rotating unit 52 drives the rotating component 521 to rotate, which in turn drives the clamping ring disk 42 to rotate. This facilitates the relative rotational connection between the chassis 44 and the rotating component 521, and facilitates the relative rotation between the inner disc 41 and the outer disc 43 and the clamping ring disk 42, resulting in a speed difference.
[0070] The first rotating unit 51 includes a rotating motor 511, which is fixedly connected to the outer wall of the splitting cylinder 2 via a mounting bracket 515. The output end of the rotating motor 511 is fixedly connected to a driving wheel 512 along the coaxial center line. The driving wheel 512 is connected to a driven wheel 514 via a synchronous belt 513. The driven wheel 514 is sleeved on the rotating part 521 and is fixedly connected to the chassis 44 along the coaxial center line via a connecting ring 53. Rotary bearings 516 are provided below both the driving wheel 512 and the driven wheel 514. The outer rings of the two rotary bearings 516 are fixed on the base plate 11, and the inner rings are respectively connected to the driving wheel 512 and the driven wheel 514 along the coaxial center line.
[0071] With the above structure, the drive wheel 512 is driven to rotate by the rotary motor 511, and the drive wheel 512 drives the driven wheel 514 to rotate through the synchronous belt 513, so that the driven wheel 514 drives the inner disc 41 and the outer ring disc 43 to rotate synchronously through the chassis 44.
[0072] The second rotating unit 52 is located inside the rotating bearing 516, which is coaxially connected to the driven wheel 514. Specifically, in the second rotating unit 52, the rotating device 525 is a servo motor, which is fixed above the base plate 11 by a fixing seat 5265. The rotating device 525 is coaxially connected to a horizontally axially rotating shaft 524. A positioning frame 5264 is provided at the end of the rotating shaft 524 away from the rotating device 525 to support the rotating shaft 524 to rotate smoothly around its own axis. The cross-section of the rotating shaft 524 is cross-shaped. The outer sealing sleeve of the rotating shaft 524 is provided with a rotating wheel 523 that slides with it. An annular mounting groove is provided on the circumferential outer edge of the rotating wheel 523. An elastic sleeve 528 is fixedly connected to the inner wall of the mounting groove. The elastic sleeve 528 is a rubber sleeve used to abut against the bottom surface of the rotating part 521. The translation unit 526 is used to drive the rotating wheel 523 to slide along the axial direction of the rotating shaft 524 and adjust the axial position of the rotating wheel 523.
[0073] In the second rotating unit 52, the axial position of the rotating wheel 523 relative to the rotating shaft 524 can be adjusted and positioned by the translation unit 526. The rotating device 525 drives the rotating shaft 524 to rotate in a fixed direction and at a fixed speed, so that the rotating wheel 523 maintains a constant speed and orientation. The rotating wheel 523 acts on the rotating component 521 through the elastic sleeve 528, causing the rotating component 521 to rotate around its own axis. The rotating component 521 and the clamping ring disk 42 are magnetically attracted to each other, so that the clamping ring disk 42 rotates synchronously. When the axial position of the rotating wheel 523 is changed by the translation unit 526, the contact position between the elastic sleeve 528 on the rotating wheel 523 and the rotating component 521 changes, thereby changing the rotation speed of the rotating component 521, and thus changing the rotation speed of the clamping ring disk 42. A through hole is provided at the center of the rotating component 521. When the rotating wheel 523 moves along the rotating shaft 524 to the position directly opposite the through hole, the elastic sleeve 528 disengages from the rotating component 521. In this state, although the rotating wheel 523 and the elastic sleeve 528 maintain rotation, they do not act on the rotating component 521, so that the rotating component 521 does not rotate regardless of the rotation of the rotating wheel 523. Correspondingly, the clamping ring disk 42 also maintains the same state as the rotating component 521. In other positions, the elastic sleeve 528 is in contact with the rotating component 521. The closer the distance from the axis of the clamping disc 42 is to the axis of rotation, the greater the rotational speed of the clamping disc 42 and the rotating component 521. Conversely, the farther the distance from the axis of rotation of the clamping disc 42 is to the axis of rotation, the smaller the rotational speed of the clamping disc 42 and the rotating component 521. In addition, when the rotating wheel 523 moves from one side of the axis of rotation of the clamping disc 42 to the other side while keeping the elastic sleeve 528 in contact with the rotating component 521, the rotational direction of the clamping disc 42 and the rotating component 521 changes, further increasing the possibility of collision between rubber products and improving the waste edge separation efficiency.
[0074] A further improvement is that a translation bearing 527 is provided between the output end of the translation unit 526 and the rotating wheel 523. The translation bearing 527 is sleeved on the outside of the rotating shaft 524 and connected to the rotating wheel 523.
[0075] Specifically, such as Figures 9-11 As shown, the translation unit 526 includes a translation motor 5261 mounted on a fixed base 5265. A translation screw 5262 is fixedly connected to the output end of the translation motor 5261 along the coaxial centerline. The end of the translation screw 5262 away from the translation motor 5261 is rotatably mounted on a positioning frame 5264. A translation sleeve 5263 is threadedly connected to the translation screw 5262. The bottom surface of the translation sleeve 5263 is in contact with the top surface of the base plate 11. Two translation bearings 527 are provided, respectively located on both sides of the rotating wheel 523. The inner ring of the translation bearing 527 is fixedly connected to the rotating wheel 523 along the coaxial centerline and sleeved on the outside of the rotating shaft 524. The outer ring is fixedly connected to the translation sleeve 5263.
[0076] With the above structure, the translation motor 5261 drives the translation screw 5262 to rotate, which acts on the translation screw sleeve 5263, causing the translation screw sleeve 5263 to move along the circumference of the base plate 11 and drive the translation bearing 527 to move, thereby adjusting the axial position of the rotating wheel 523 and changing the rotation speed of the clamping disc 42.
[0077] A further improvement is that the clamping disc 42 and the rotating component 521 are respectively provided with a first magnetic suction component 421 and a second magnetic suction component 5211 that are adjacent to each other and are both U-shaped. The inner wall of the first magnetic suction component 421 is connected to the bottom surface, the outer edge of the circumferential direction and the inner wall of the clamping disc 42.
[0078] Specifically, multiple first magnetic attractors 421 and second magnetic attractors 5211 are provided and correspond one-to-one. The first magnetic attractors 421 are distributed in an equally spaced ring array on the clamping disk 42, and the second magnetic attractors 5211 are distributed in an equally spaced ring array on the rotating member 521. Both are U-shaped and closely adjacent to each other. In this way, by reducing the spacing and increasing the magnetic attraction area, the magnetic attraction force between the rotating member 521 and the clamping disk 42 is increased, so that the two can maintain synchronous rotation.
[0079] It should be noted that, in order to ensure that the inner disk 41 rotates synchronously with the rotating component 521, the inner disk 41, the clamping disk 42, and the outer ring disk 43 are preferably made of non-magnetic materials such as plastic and glass to avoid mutual interference between the magnetic fields of the first magnetic chuck 421 and the second magnetic chuck 5211. Furthermore, the first magnetic chuck 421 and the second magnetic chuck 5211 are arranged adjacent to each other to ensure mutual attraction. The first magnetic chuck 421 and the second magnetic chuck 5211 can be selected in two ways: first, both are strong magnets that attract each other; second, one of them is a metal that can be attracted by a magnet, such as iron, nickel, or cobalt, and the other is a strong magnet. Using either of these two methods ensures that after the two are respectively installed on the clamping disk 42 and the rotating component 521, the clamping disk 42 can rotate with the rotation of the rotating component 521. To further ensure that the clamping disc 42 rotates synchronously with the rotating component 521, during the rotation of the rotating shaft 524 driven by the rotating motor 525 around its own axis, when the rotating shaft 524 changes from a stationary state to a rotating state, before controlling the rotating shaft 524 to rotate at a constant speed and direction, the rotating motor first controls the rotating shaft 524 to slowly increase its speed, so that the speed of the rotating component 521 slowly increases, so as to ensure that the clamping disc 42 can keep up with the speed of the rotating component 521 even when it is separated from the rotating component 521. Of course, in order to reduce the friction between the clamping disc 42 and the inner disc 41 and the outer disc 43, lubricating oil can be applied to the circumferential inner wall and circumferential outer edge of the clamping disc 42 to reduce the resistance encountered by the clamping disc 42 when rotating, thereby further ensuring the synchronous rotation of the clamping disc 42 and the rotating component 521.
[0080] Third Embodiment
[0081] like Figure 12 and Figure 13 As shown, the centrifugal edge removal machine of the third embodiment is based on the second embodiment, except that the baffle assembly 6 adjacent to the centrifugal disc 4 includes a rigid member 611 and an elastic cover 612. The elastic cover 612 in its natural state is curved and is connected to the rigid member 611.
[0082] Specifically, the elastic cover 612 is made of rubber. In its natural state, both the inner and outer surfaces of the elastic cover 612 are concentric hemispherical shapes. The outer diameter of the elastic cover 612 is the same as the inner diameter of the splitting cylinder 2. The rigid member 611 is a rigid plate with a thickness that is the same as the width of the arc-shaped opening 22. A circular through hole is provided on the rigid member 611, and the center of the elastic cover 612 is located on the axis of the circular through hole.
[0083] With the above structure, since the elastic cover 612 can undergo elastic deformation, when the elastic cover 612 moves to the first station, it increases the contact area between the baffle 61 and the rubber product, thereby facilitating the collision of more rubber products on the baffle 61. This is beneficial to improving the separation effect of the flash of the rubber product.
[0084] Further improvements include placing the arc-shaped opening 22 corresponding to the elastic cover 612 close to the discharge port 21 above it. This further compresses the space available for movement during the separation of waste edges of rubber products, increases the collision frequency between the rubber products and the inner wall of the splitting cylinder 2, and between the rubber products themselves. This makes it easier for the waste edges on the outer circumferential edge of the rubber products to detach from the rubber products due to impact, thereby improving the quality of product edge separation and increasing processing efficiency.
[0085] Fourth embodiment
[0086] like Figures 14-20 As shown, the centrifugal edge removal machine of the fourth embodiment is based on the third embodiment, except that an air injection channel 23 is provided on the circumferential side wall of the splitting cylinder 2, located below the material blocking assembly 6. One end of the air injection channel 23 is connected to the inner cavity of the splitting cylinder 2, and the other end is used to connect to the air injection device 7 to inject airflow into the splitting cylinder 2. The air injection channel 23 is inclined upward toward the inner cavity of the splitting cylinder 2. An air injection sleeve 24 is provided on the circumferential outer edge of the splitting cylinder 2 to form an air injection cavity. An air injection pipe 25 is provided on the air injection sleeve 24 for communicating with the air injection device 7. The air injection pipe 25, the air injection cavity, the air injection channel 23 and the inner cavity of the splitting cylinder 2 are connected in sequence.
[0087] Specifically, the bottom of the circumferential sidewall of the splitting cylinder 2 is provided with three air injection components distributed along its own axis. The air injection components include an air injection sleeve 24 fixedly sleeved outside the splitting cylinder 2, an air injection pipe 25 fixed on the air injection sleeve 24, and air injection through holes 27 evenly spaced in a ring array on the air injection sleeve 24. One end of the air injection channel 23 is fixed to the inner wall of the air injection through hole 27, facing the axis of the splitting cylinder 2, and the other end extends downward into the air injection cavity formed by the air injection sleeve 24 and the splitting cylinder 2.
[0088] The air injection device 7 includes an air pump 71, which is fixed above the base plate 11. The input end of the air pump 71 is connected to a filter device 8, which includes a filter screen. The output end of the air pump 71 is connected to an air injection shell 72. The side of the air injection shell 72 away from the air pump 71 is covered with a shell cover 73, which is fixedly connected to the air injection pipe 25.
[0089] With the above structure, when centrifugally separating the waste edges of rubber products, the air pump 71 is started to draw in external air. The filter device 8 removes dust and impurities from the air, allowing clean air to enter the air injection shell 72. This clean air then enters the air injection chamber through the air injection pipe 25, and then flows into the inner side of the splitting cylinder 2 through the air injection channel 23. Multiple airflows are formed inside the splitting cylinder 2, blowing upwards towards the axis of the splitting cylinder 2. This airflow, on the one hand, agitates the centrifuged rubber products inside the splitting cylinder 2, causing them to flip towards the upper middle part of the cylinder, preventing them from touching at the bottom edge. This expands the range of motion of the rubber products, thereby increasing... This reduces the probability of collisions with rubber products. Furthermore, after being affected by the airflow, the rubber products approach the axis of the splitting cylinder 2 and then fall downwards onto the rotating centrifugal disc 4. The rotating centrifugal disc 4 then rotates the rubber products again, causing them to be subjected to centrifugal force and collide with other rubber products or with the inner wall of the splitting cylinder 2. They are then affected by the airflow. In this way, the rubber products are subjected to multiple centrifugal actions, thereby increasing the probability of collisions and improving the centrifugal edge removal effect. Moreover, compared to rigid stirring components, the airflow acting on the rubber products avoids damage to the rubber products and ensures safe processing and production.
[0090] To prevent a surge in air pressure caused by continuous airflow into the splitting cylinder 2, an exhaust vent 311 is provided on the discharge plate 31. The exhaust vent 311 facilitates the discharge of excess gas from the splitting cylinder 2, keeping the air pressure inside the splitting cylinder 2 basically consistent with the outside air pressure. This allows for continuous airflow, which drives the rubber products inside the splitting cylinder 2 to flip and collide towards the upper center, and then fall onto the centrifugal disc 4. Through multiple centrifugal processes, waste edges are removed, thereby improving the splitting effect and enhancing product quality.
[0091] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
