Description

Technical Field

[0001] This invention relates to the field of gasket feeding equipment technology, specifically a gasket material feeding mechanism. Background Technology

[0002] In the field of industrial automated assembly, metal gaskets are commonly used sealing and buffering components. The jamming and conveying efficiency of their automated feeding process directly determine the continuous operation capability and product qualification rate of the entire production line. Currently, most gasket feeding mechanisms on the market adopt a structure of vibratory feeder combined with straight cylindrical conveying pipe, or a separate feeding structure driven by multiple power sources, to achieve batch conveying and single-piece separation of gaskets.

[0003] However, the main shortcomings of conventional gasket feeding mechanisms are that they are prone to jamming during operation and have low overall feeding efficiency. On the one hand, the surface of metal gaskets usually has residual anti-rust oil stains, which easily cause them to stick and clump together. The agitation method of traditional vibratory feeders is difficult to completely break up the sticky gaskets. Moreover, the feeding and separation actions lack precise timing matching, which easily leads to the situation of "separation not completed, material replenishment has arrived" and the gaskets are stuck in the conveying pipe, reducing the feeding efficiency. On the other hand, the power source control of existing mechanisms is unreasonable. Either the coordination of multiple power sources is complicated, which easily leads to timing misalignment and aggravates jamming, or the division of labor of power sources is not clear, which cannot achieve efficient linkage of feeding, separation and transfer. At the same time, the traditional conveying structure lacks effective posture guidance, and the gaskets are prone to tilting, tipping over and blocking the conveying pipe, further reducing the feeding efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a gasket material feeding mechanism to solve the problems mentioned in the background art.

[0005] The objective of this invention can be achieved through the following technical solutions: A gasket material feeding mechanism, preferably, includes a base, a pushing mechanism, a feeding mechanism, and a conveying pipe. The feeding mechanism includes a feeding platform support fixed to the top of the base, symmetrically arranged hoppers on the top of the feeding platform support, feeding bowls connected to the bottom of the hoppers, a rotating shaft rotatably connected to the feeding platform support, the rotating shaft passing through the two hoppers and fixed with a pair of cross steel brushes, a receiving platform slidably connected to the feeding platform support, and a feeding motor connected to the rotating shaft. The receiving platform is equipped with a saturation feeding mechanism and a triggering mechanism. The saturation feeding mechanism includes a guide chamber, a mixing chamber, a separation pipe, a cross-shaped material distribution plate, a mixing rod, and a transmission assembly. The triggering mechanism is linked to the pushing cylinder and the feeding platform support. The feeding mechanism includes a feeding cylinder, a sliding docking platform, a feeding guide rail, a feeding slider, and a suction platform. The suction platform is provided with a gasket storage hole, a suction hole, and an annular flow channel. The sliding docking platform is provided with an air pipe. The feed pipe is equipped with helical rifling. The single-power drive and linkage triggering achieve limited single-piece conveying of gaskets, preventing sticking and jamming, and improving conveying efficiency.

[0006] Preferably, the feeding platform support of the feeding mechanism has two symmetrically arranged material bins on top, two cross steel brushes are respectively installed inside the two material bins, and two receiving platforms are respectively located at the discharge ports below the two feeding bowls. The top receiving port of the receiving platform is connected to the feeding bowl, and the bottom discharge port is connected to the conveying pipe.

[0007] Preferably, the cross-shaped steel brush is fixedly connected to the rotating shaft and rotates synchronously with the rotating shaft to agitate the pads in the feeding bowl and sweep the pads into the top receiving port of the receiving platform.

[0008] Preferably, the guide chamber and mixing chamber of the saturation feeding mechanism are located inside the receiving platform, and the separation pipe connects the guide chamber and the mixing chamber. The input end of the guide chamber is located at the bottom of the feeding bowl, and the cross-shaped material distribution plate is concentrically connected to the inside of the guide chamber. Four material embedding slots adapted to the inlet of the separation pipe are evenly arranged on its outer periphery, and the inner diameter of the separation pipe inlet is slightly larger than the material embedding slots.

[0009] Preferably, the transmission assembly includes a first synchronous wheel fixed to the middle section of the rotating shaft, a synchronous shaft rotatably connected to the top of the base, and a second synchronous wheel fixed to the middle section of the synchronous shaft. Synchronous belts are sleeved on the outer circumference of the first and second synchronous wheels. A first bevel gear is fixed at both ends of the synchronous shaft, and a second bevel gear that meshes with the first bevel gear is fixed at the end of the cross-shaped material distribution disc shaft.

[0010] Preferably, the separation port of the triggering mechanism is opened at the top of the separation pipe and is arranged along the length of the separation pipe. The side L-shaped separation platform is movably inserted into the separation port. One end of the platform is fixed with a guide slide rod and is slidably connected to the bottom of the feeding bowl. The distance between the two side L-shaped separation platforms is slightly greater than the thickness of a shim. The distance between the top of the top side L-shaped separation platform and the bottom of the material embedding groove is the thickness of a shim. A reset spring is fixed on the side of the side L-shaped separation platform away from the separation pipe.

[0011] Preferably, the abutment wheel of the triggering mechanism is fixed to one side of the L-shaped separation platform, and the cam is rotatably connected to the top of the base and located between two adjacent abutment wheels. When the cam rotates, it presses against the abutment wheel, pushing the two L-shaped separation platforms to complete the alternating insertion and removal movement.

[0012] Preferably, a damper is provided at the camshaft end of the triggering mechanism, and a ratchet is fixed at the other end of the cam. The triggering mechanism also includes a triggering ramp, a triggering slide bar, and a traction slide bar. The triggering ramp is fixed to the top of the sliding dock, the triggering slide bar is slidably disposed on the top of the base, its bottom is rotatably connected to a triggering roller that abuts against the triggering ramp, its middle section is fixed with an abutment ring, its top passes through the base and is fixed with an L-shaped mounting bracket, and its outer periphery is fitted with a reset spring. The traction slide bar is slidably connected to one end of the L-shaped mounting bracket, the ratchet rack is fixed between the two traction slide bars and meshes with the ratchet gear, and an unlocking spring is sleeved on one end of the traction slide bar.

[0013] Preferably, the pushing cylinders of the pushing mechanism are symmetrically fixed on the base, the sliding dock is fixed to the top end of the pushing cylinder, the pushing guide rail is symmetrically fixed on the base, and the bottom of the sliding dock is fixed with a pushing slider adapted to the pushing guide rail. The suction platform is located at the end of the sliding dock. Suction holes are evenly opened at the bottom of the gasket storage hole and arranged in a circular pattern. An annular flow channel is opened on the outer periphery of the suction platform and communicates with the bottom of the suction holes. The air pipe is connected to the suction holes through the annular flow channel.

[0014] Preferably, the bottom of the mixing chamber of the saturation feeding mechanism is set as a conical surface facing the direction of the conveying pipe, and the shaft end of the cross-shaped material distribution plate extends into the interior of the mixing chamber and is symmetrically fixed with stirring rods; The helical rifling inside the feed tube guides the gasket to slide smoothly downwards, preventing the gasket from becoming misaligned or stuck.

[0015] The beneficial effects of this invention are: 1. This invention uses a cross-shaped steel brush to pre-break up the clumps of gaskets, and a cross-shaped material distribution plate to achieve preliminary limited separation of the gaskets. Two side L-shaped separation platforms complete the "insertion and retraction" actions in sequence, achieving precise single-piece separation of the gaskets and avoiding the stacking of two or more gaskets. At the same time, the saturation feeding mechanism and the triggering mechanism achieve precise timing matching. When the side L-shaped separation platform is performing the separation action, the cross-shaped material distribution plate controls the material embedding groove to deviate from the inlet of the separation pipe, so as to avoid the risk of material stacking caused by "material separation not being completed but feeding already in place". Combined with the de-adhesion effect of the stirring rod and the attitude guidance of the spiral rifling of the conveying pipe, the gasket skewing and pipe jamming phenomena are significantly reduced, and the feeding stability is improved.

[0016] 2. This invention uses a feeding motor as the core power source for material supply. Through a transmission assembly, it synchronously drives the cross steel brush, cross separating disc, and stirring rod to break up, initially separate, and de-stick the gaskets, laying the foundation for preventing jamming. At the same time, the pushing cylinder acts as the triggering and transfer power source, driving the sliding dock to move. On the one hand, it triggers the mechanism to start, driving the side L-shaped separation table to complete the separation of individual pieces. On the other hand, it achieves precise transfer of the gaskets. The two power sources do not interfere with each other and are matched in timing, further reducing the risk of jamming. It also achieves efficient connection between feeding, separation, and transfer, greatly improving the feeding efficiency.

[0017] 3. This invention utilizes a precise linkage between a triggering mechanism and a saturation feeding system. The triggering mechanism, activated by a pushing cylinder, rotates a cam, causing the two L-shaped separating platforms to sequentially perform "insertion and retraction" actions, separating the gaskets at the inlet of the separation pipe one by one, effectively preventing material stacking and jamming. When the triggering mechanism is activated, the saturation feeding mechanism precisely controls the cross-shaped distribution plate, ensuring the material embedding groove deviates from the inlet of the separation pipe, eliminating the risk of material stacking before separation is complete. Simultaneously, the cross-shaped distribution plate drives the stirring rod to rotate, breaking up oil and dirt adhesion on the gasket surface. Combined with the conical guide surface of the stirring chamber and the spiral rifling of the conveying pipe, this ensures stable gasket delivery without skew or jamming. Furthermore, the damper and unlocking spring of the triggering mechanism work together to prevent accidental cam rotation leading to repeated feeding, achieving precise "one-piece-at-a-time" control, thoroughly reducing jamming and avoiding ineffective feeding.

[0022] like Figures 1-13As shown, it includes a base 1, a pushing mechanism, a feeding mechanism and a conveying pipe 2. The feeding mechanism includes a feeding platform support 3 fixed to the top of the base 1. A material bin 4 is symmetrically arranged on the top of the feeding platform support 3. A feeding bowl 5 is connected to the bottom of the material bin 4. The feeding platform support 3 is rotatably connected to a rotating shaft 6. The rotating shaft 6 passes through the two material bins 4 and is fixed with a pair of cross steel brushes 7. The feeding platform support 3 is slidably connected to a receiving platform 8. A feeding motor 9 is also fixed and connected to the rotating shaft 6. The receiving platform 8 is equipped with a saturation feeding mechanism and a triggering mechanism. The saturation feeding mechanism includes a guide chamber 10, a mixing chamber 11, a separation pipe 12, a cross-shaped material distribution plate 13, a mixing rod 14, and a transmission assembly. The triggering mechanism is linked to the pushing cylinder 15 and the feeding platform support 3. The feeding mechanism includes a feeding cylinder 15, a sliding docking platform 16, a feeding guide rail 17, a feeding slider 18, and a suction platform 19. The suction platform 19 is provided with a gasket storage hole 45, a suction hole 46, and an annular flow channel. The sliding docking platform 16 is provided with an air pipe 20. The feed pipe 2 is equipped with helical rifling. Among them, the feeding platform support 3 of the feeding mechanism is symmetrically provided with two material bins 4 on the top, and two cross steel brushes 7 are respectively installed inside the two material bins 4. The two receiving platforms 8 are respectively located at the discharge port below the two feeding bowls 5, and the top receiving port of the receiving platform 8 is connected to the feeding bowl 5, and the bottom discharge port is connected to the conveying pipe 2. Furthermore, the cross steel brush 7 is fixedly connected to the rotating shaft 6 and rotates synchronously with the rotating shaft 6. It is used to stir the pads in the feeding bowl 5 and sweep the pads into the top receiving port of the receiving platform 8. Furthermore, the guide chamber 10 and the mixing chamber 11 of the saturated feeding mechanism are located inside the receiving platform 8. The separation pipe 12 connects the guide chamber 10 and the mixing chamber 11. The input end of the guide chamber 10 is located at the bottom of the feeding bowl 5. The cross-shaped material distribution plate 13 is concentrically connected to the inside of the guide chamber 10. Four material embedding slots 43 that are adapted to the inlet of the separation pipe 12 are evenly arranged on its outer periphery. The inner diameter of the inlet of the separation pipe 12 is slightly larger than that of the material embedding slots 43. Furthermore, the transmission assembly includes a first synchronous wheel 21 fixed to the middle section of the rotating shaft 6, a synchronous shaft 22 rotatably connected to the top of the base 1, and a second synchronous wheel 23 fixed to the middle section of the synchronous shaft 22. A synchronous belt 24 is sleeved on the outer periphery of the first synchronous wheel 21 and the second synchronous wheel 23. A first bevel gear 25 is fixed at both ends of the synchronous shaft 22, and a second bevel gear 26 that meshes with the first bevel gear 25 is fixed at the shaft end of the cross-shaped material distribution disc 13. Furthermore, the separation port 44 of the triggering mechanism is opened at the top of the separation pipe 12 and is set along the length of the separation pipe 12. The side L-shaped separation platform 27 is movably inserted into the separation port 44. One end of the platform is fixed with a guide slide rod 28 and is slidably connected to the bottom of the feeding bowl 5. The distance between the two side L-shaped separation platforms 27 is slightly greater than the thickness of a shim. The distance between the top of the top side L-shaped separation platform 27 and the bottom of the material embedding groove 43 is the thickness of a shim. A reset spring 29 is fixed on the side of the side L-shaped separation platform 27 away from the separation pipe 12. Furthermore, the triggering mechanism's abutment wheel 30 is fixed to one side of the side L-shaped separation platform 27, and the cam 31 is rotatably connected to the top of the base 1 and located between two adjacent abutment wheels 30. When the cam 31 rotates, it presses against the abutment wheel 30, pushing the two side L-shaped separation platforms 27 to complete the alternating insertion and removal movement. Furthermore, a damper 32 is provided at the shaft end of the cam 31 of the triggering mechanism, and a ratchet 33 is fixed at the other end of the cam 31. The triggering mechanism also includes a triggering ramp 34, a triggering slide bar 35, and a traction slide bar 40. The triggering ramp 34 is fixed to the top of the sliding dock 16, the triggering slide bar 35 is slidably disposed on the top of the base 1, the bottom of which is rotatably connected to a triggering roller 36 that abuts against the triggering ramp 34, the middle section is fixed with an abutment ring 37, the top passes through the base 1 and is fixed with an L-shaped mounting bracket 38, and the outer periphery is fitted with a return spring 39. The traction slide bar 40 is slidably connected to one end of the L-shaped mounting bracket 38. The ratchet rack 41 is fixed between the two traction slide bars 40 and meshes with the ratchet gear 33. An unlocking spring 42 is sleeved on one end of the traction slide bar 40. Furthermore, the pushing cylinder 15 of the pushing mechanism is symmetrically fixed on the base 1, the sliding docking platform 16 is fixed on the top end of the pushing cylinder 15, the pushing guide rail 17 is symmetrically fixed on the base 1, and the bottom of the sliding docking platform 16 is fixed with a pushing slider 18 that is compatible with the pushing guide rail 17. The suction platform 19 is located at the end of the sliding docking platform 16. The suction holes 46 are evenly opened at the bottom of the gasket storage hole 45 and arranged in a circular pattern. The annular flow channel is opened on the outer periphery of the suction platform 19 and communicates with the bottom of the suction holes 46. The air pipe 20 is connected to the suction holes 46 through the annular flow channel. Furthermore, the bottom of the mixing chamber 11 of the saturated feeding mechanism is set as a conical surface 47 facing the direction of the conveying pipe 2, and the shaft end of the cross-shaped material distribution plate 13 extends into the interior of the mixing chamber 11 and is symmetrically fixed with a mixing rod 14. The spiral rifling inside the feed pipe 2 is used to guide the gasket to slide smoothly downwards, preventing the gasket from becoming skewed or stuck.

[0023] In use, the operator loads the metal pads to be conveyed into the hopper 4 in batches, and then starts the feeding motor 9 to run continuously at a preset constant speed, driving the rotating shaft 6 fixedly connected to it to rotate synchronously. When the rotating shaft 6 rotates, the cross steel brush 7 on its outer periphery will continuously agitate the metal pads in the feeding bowl 5 at the bottom of the hopper 4, quickly breaking up the pads that are stuck together due to surface oil stains, and gradually sweeping the loose pads into the receiving port at the top of the receiving platform 8. Meanwhile, the rotating shaft 6 drives the synchronous shaft 22 to rotate through the synchronous pulley 21, synchronous belt 24 and synchronous pulley 23. Through the meshing transmission of bevel gear 25 and bevel gear 26, the cross-shaped material distribution plate 13 will rotate concentrically inside the guide chamber 10. The material embedding groove 43 on its outer periphery will pass through the input end of the guide chamber 10 in sequence, embedding the gaskets one by one and pushing them to the inlet of the separation pipe 12. After the pre-storage of one gasket is completed, the cross-shaped material distribution plate 13 will continue to rotate, so that the material embedding groove 43 is completely deviated from the inlet of the separation pipe 12. At this time, the mechanism enters a stable standby state, effectively preventing the gaskets from sliding into the separation pipe 12 on their own during the standby period and causing material stacking. When the subsequent workstation on the production line issues a gasket feeding instruction, the pusher cylinder 15 drives the sliding dock 16 to move along the pusher guide rail 17 towards the bottom of the conveying pipe 2. During the movement of the sliding dock 16, the trigger ramp 34 at its top will roll against the trigger roller 36 at the bottom of the trigger slide rod 35, pushing the trigger slide rod 35 to slide upward along the base 1, while simultaneously compressing the second reset spring 39 to complete energy storage. As the trigger slide rod 35 moves upward, its top L-shaped mounting bracket 38 drives the ratchet rack 41 to move upward synchronously. The ratchet rack 41 meshes with the ratchet gear 33 at the shaft end of the cam 31, directly driving the cam 31 to complete a full 360° rotation. When the cam 31 rotates, it will contact and engage with the abutting wheels 30 on one side of the two L-shaped separating platforms 27 in sequence: First, the protruding end of the cam 31 presses against the abutting wheel 30 of the first L-shaped separating platform 27, pushing the L-shaped separating platform 27 to slide along the guide slide rod 28 and insert into the separating socket 44. After it is fully in place, the cam 31 continues to rotate, the protruding end disengages from the abutting wheel 30, and the return spring 29 immediately rebounds, causing the first L-shaped separating platform 27 to be pulled out of the separating socket 44. After the first L-shaped separating platform 27 is fully reset, the protruding end of the cam 31 will contact the abutting wheel 30 of the second L-shaped separating platform 27, repeating the above pressing and resetting actions. The sequential operation of the two side L-shaped separation platforms 27 will first receive the single gasket pre-stored at the inlet of the separation pipe 12 on the top side L-shaped separation platform 27 and then drop it to the lower side L-shaped separation platform 27. Finally, it will be released by the lower side L-shaped separation platform 27 and fall smoothly into the mixing chamber 11. There will be no stacking of two or more gaskets throughout the process, which effectively reduces the problem of oily gaskets easily stacking and getting stuck. During the entire process of single-piece separation by the L-shaped separating table 27 driven by the cam 31, the cross-shaped material distribution plate 13 driven by the feeding motor 9 drives the material embedding groove 43 to rotate to a position away from the inlet of the separation pipe 12. This ensures that during the separation of the gaskets by the L-shaped separating table 27, no new gaskets are added at the inlet of the separation pipe 12. This perfectly avoids the risk of material stacking that may occur when the two independent drive sources of the saturation feeding mechanism and the triggering mechanism work together, such as "separation not completed, material replenishment already in place". It achieves precise timing matching between feeding and separation. After the gasket falls into the mixing chamber 11, the stirring rod 14 at the shaft end of the cross-shaped distribution plate 13 rotates synchronously with the cross-shaped distribution plate 13, continuously agitating the gasket in the mixing chamber 11. This completely breaks up the slight adhesion caused by residual oil on the gasket surface, keeping the gasket in an independent and loose state. At the same time, the conical surface 47 at the bottom of the mixing chamber 11 cooperates with the weight of the gasket, giving the gasket a continuous thrust in the direction of the conveying pipe 2, pushing the gasket smoothly into the conveying pipe 2. After the gasket enters the conveying pipe 2, the helical rifling inside guides the sliding posture of the gasket. The gasket, which may have been tilted, gradually adjusts to a horizontal and parallel posture under the action of the rifling, sliding smoothly downward along the conveying pipe 2, and finally falling precisely into the gasket storage hole 45 of the suction platform 19 at the end of the sliding dock 16. The instant the gasket falls into the gasket storage hole 45, the air pipe 20, which is connected to the annular flow channel of the suction table 19, outputs a stable negative pressure. This generates a continuous suction force through the suction hole 46 at the bottom of the gasket storage hole 45, firmly adhering the gasket to the gasket storage hole 45 and preventing the gasket from falling or shifting during subsequent transfer. At this time, the pusher cylinder 15 immediately drives the sliding dock 16 to move along the pusher guide rail 17 to the subsequent processing workpiece. During the movement of the sliding dock 16, the trigger ramp 34 gradually disengages from the trigger roller 36, and the reset spring 2 39 releases its stored energy, causing the trigger slide bar 35 and the ratchet rack 41 to move down synchronously. When the ratchet 41 moves downward, the damper 32 at the shaft end of the cam 31 will generate a stable damping torque, preventing the ratchet 33 from rotating with the ratchet 41. At the same time, the unlocking spring 42 on the outer periphery of the traction slide bar 40 will undergo elastic deformation, allowing the ratchet 41 to smoothly disengage from the ratchet 33. Throughout the process, the cam 31 remains stationary and will not rotate erroneously due to the downward movement of the ratchet 41, effectively avoiding the problem of the trigger mechanism being accidentally activated during the transfer process, which would lead to repeated feeding of materials into the separation pipe 12. When the sliding dock 16 moves the pad to the designated processing station, the fiber optic sensor at the station immediately senses that the pad is in place and sends a "ready to pick up" signal to the subsequent station. The picking mechanism at the subsequent station will quickly pick up the pad from the pad storage hole 45, completing the feeding process for a single pad. After picking up the pad, the pusher cylinder 15 will drive the sliding dock 16 to reverse and reset along the pusher guide rail 17. When the sliding dock 16 moves to the bottom of the feed pipe 2 again, the trigger mechanism will start again, driving the cam 31 to rotate, completing the single-piece separation of the next pad. At the same time, the cross-shaped material distribution plate 13 will simultaneously complete the pre-storage and limit of the new pad, and the entire mechanism will enter the next complete feeding cycle.

[0024] The working principle of the gasket material feeding mechanism provided by this invention is as follows: First, start the feeding motor 9, which drives the rotating shaft 6 fixedly connected to it to rotate synchronously. When the rotating shaft 6 rotates, the cross steel brush 7 will continuously stir the pads in the feeding bowl 5 at the bottom of the hopper 4. On the one hand, it prevents the pads from sticking together due to oil stains. On the other hand, it gradually sweeps the stirred pads into the receiving port at the top of the receiving platform 8 corresponding to the discharge port below the feeding bowl 5. When the rotating shaft 6 rotates, it drives the synchronous pulley 21 fixed in its middle section to rotate. The synchronous pulley 21 drives the synchronous pulley 23 in the middle section of the synchronous shaft 22 to rotate through the synchronous belt 24 sleeved on the outer periphery, thereby driving the synchronous shaft 22 to rotate. The bevel gear 25 fixed at both ends of the synchronous shaft 22 meshes with the bevel gear 26 fixed at the shaft end of the cross-shaped material distribution plate 13, ultimately driving the cross-shaped material distribution plate 13 to rotate concentrically inside the guide chamber 10. As the pads agitated by the cross steel brush 7 continue to enter the guide chamber 10, the cross distribution plate 13 rotates synchronously. The material embedding groove 43 on its outer periphery passes through the input end of the guide chamber 10 in sequence, embedding the pads entering the guide chamber 10 individually into the material embedding groove 43. Then, the cross distribution plate 13 pushes the pads to the inlet of the separation pipe 12, realizing the initial limited separation of the pads. At this point, it is important to note that the saturation feeding mechanism and the triggering mechanism are two independent drive sources. The saturation feeding mechanism is driven by the feeding motor 9, and the triggering mechanism is triggered by the sliding action of the sliding dock 16. The two work together without interfering with each other. When the triggering mechanism is activated and the two side L-shaped separation tables 27 are ready to separate single gaskets, the saturation feeding mechanism will precisely control the cross-shaped material distribution plate 13. Under the premise of ensuring that a gasket has been received at the inlet of the separation pipe 12, the material embedding groove 43 is driven away from the top of the inlet of the separation pipe 12. This prevents the gasket in the material embedding groove 43 from falling and stacking with the gasket already at the inlet of the separation pipe 12, effectively eliminating the risk of material jamming and ensuring the stability of single-piece separation. When the sliding dock 16 moves to the bottom of the conveying pipe 2 under the drive of the pushing cylinder 15, the trigger ramp 34 fixed at the top of the sliding dock 16 rolls against the trigger roller 36 at the bottom of the trigger slide rod 35, pushing the trigger slide rod 35 to slide upward along the base 1. The contact ring 37 in the middle of the trigger slide rod 35 compresses the reset spring 39 to store energy. At the same time, the L-shaped mounting bracket 38 fixed at the top of the trigger slide rod 35 drives the ratchet rack 41 to move upward. The ratchet rack 41 meshes with the ratchet gear 33 fixed at the other end of the cam 31, driving the cam 31 to rotate 360 ​​degrees, completing the sequential operation of the two side L-shaped separation platforms 27, and realizing that a single gasket falls from the separation pipe 12 into the mixing chamber 11. The specific process is as follows: when the cam 31 rotates, its protruding end first First, the cam 31 contacts and compresses the first L-shaped separating platform 27 by contacting the abutment wheel 30 on one side, pushing the L-shaped separating platform 27 along the guide slide 28 and inserting it into the separating socket 44. Simultaneously, it compresses the return spring 29 on that side, storing energy. As the cam 31 continues to rotate, its protruding end disengages from the first abutment wheel 30, releasing the elastic potential energy of the return spring 29, pushing the first abutment wheel 30 back to its original position. This, in turn, causes the corresponding L-shaped separating platform 27 to be pulled out of the separating socket 44, completing one insertion and retraction action. Subsequently, the cam 31 continues to rotate, and its protruding end contacts the abutment wheel 30 on one side of the second L-shaped separating platform 27, repeating the above compression and retraction process, causing the second L-shaped separating platform 27 to complete the insertion and retraction action. Through the sequential operation of the two L-shaped separating platforms 27, the single-piece separation of the gasket is achieved. When the top L-shaped separation platform 27 is inserted, it receives a single gasket. When it is pulled out, the gasket falls to the lower L-shaped separation platform 27. When the lower L-shaped separation platform 27 is inserted, it receives the gasket. When it is pulled out, the gasket falls into the mixing chamber 11, which completely avoids two or more gaskets from being stacked and entering the subsequent conveying process, further reducing the problem of material jamming. Simultaneously, the rotation of the cross-shaped material distribution plate 13 drives the rotation of the stirring rod 14. After the gasket falls from the material embedding groove 43 into the separation pipe 12 and enters the mixing chamber 11, the stirring rod 14 continuously agitates the gasket, completely breaking up the adhesion caused by oil stains. At the same time, the conical surface 47 cooperates with the weight of the gasket to provide a guiding force towards the conveying pipe 2. Then, it falls into the gasket storage hole 45 of the suction table 19 through the conveying pipe 2. After the air pipe 20 is connected to the air source, it generates suction through the suction hole 46 to pick up and fix the gasket that has fallen into the gasket storage hole 45, preventing it from falling during movement. In addition, the conveying pipe 2 is provided with spiral rifling. After the gasket enters the conveying pipe 2, under the guidance of the rifling, it gradually forms a parallel downward sliding state, avoiding the blockage of the conveying pipe 2 caused by the gasket tilting or tipping over. This ensures that the gasket falls flat and smoothly into the suction table 19 of the pushing mechanism, effectively improving the conveying efficiency. After the gasket is fixed, the pusher cylinder 15 drives the sliding docking platform 16 to slide forward along the pusher guide rail 17, moving the gasket out from under the feed pipe 2. At this time, the trigger ramp 34 disengages from the trigger roller 36, and the reset spring 39 releases its elastic potential energy, causing the trigger slide rod 35 to move down, which in turn causes the ratchet rack 41 to move down. Since the cam 31 shaft end is equipped with a damper 32, and the ratchet rack 41 is slidably connected to the L-shaped mounting bracket 38 through the traction slide rod 40, the unlocking spring 42 sleeved on the traction slide rod 40, in conjunction with the damper 32, prevents the ratchet gear 33 from rotating as the ratchet rack 41 moves down, ensuring that the cam 31 only rotates when the sliding docking platform 16 moves to the bottom of the feed pipe 2, further reducing the problems of stacking and jamming caused by repeated feeding during the gasket conveying process. When the sliding docking station 16 moves to the designated station, the fiber optic sensor detects that the pad is in place, and the subsequent station removes the pad, completing a complete feeding process. Then, the pushing cylinder 15 drives the sliding docking station 16 to reset and repeats the above operation to achieve continuous, efficient and stable feeding of the pad.
