Description

Technical Field

[0001] The utility model relates to the technical field of rubber ring screening, in particular to a rubber ring screening machine. Background Art

[0002] When producing rubber rings, especially rubber O-rings, they need to be molded and vulcanized in a mold under a certain pressure. To prevent lack of rubber, the rubber compound filled in the mold cavity is appropriately kept with a certain interference amount. The excessive rubber compound overflows from the mold cavity and forms flash. Currently, when dealing with the flash of rubber O-rings, most of them directly use manual pulling to separate the flash, and then place it above the vibrating screening mechanism for vibrating screening separation operation. Because it is difficult to remove the stubbornly adhered flash during a single vibrating screening operation, it will remain on the surface of the rubber ring, affecting the quality of the rubber ring. Moreover, the single screening operation has a long screening time and low efficiency. Therefore, a rubber ring screening machine is needed. Content of the Utility Model

Specific implementation

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1 - 5 , a rubber ring screening machine, including a support column 1, connecting rods 2 are fixedly installed on the middle arc surfaces of the four support columns 1, a vibration screening mechanism 3 is arranged on the top of the four support columns 1, a wind screening mechanism 4 is also arranged on one side of the connecting rod 2, and a friction separation mechanism 5 is arranged on the top of the vibration screening mechanism 3.

[0024] In order to realize the vibration screening action of rubber rings and flash; the vibration screening mechanism 3 is set to include a material receiving frame 31, a vibration spring 32 is fixedly installed on the top of the support column 1, and the tops of the four vibration springs 32 are fixedly installed on the bottoms of the four sides of the material receiving frame 31. The material receiving frame 31 is in a funnel shape, and a vibration motor 33 is also fixedly installed on the inclined surface of one side of the material receiving frame 31.

[0025] Specifically implemented in this way, the vibration spring 32 fixed on the top of the support column 1 provides elasticity and vibration force for the material receiving frame 31, so that the screening process can proceed smoothly; being in a funnel shape is conducive to the smooth sliding and separation of rubber rings and flash during the vibration process; vibration helps to prevent materials from clogging on the sieve surface. Especially for flash with irregular shapes or greater viscosity, vibration can reduce the possibility of its adhesion to the sieve mesh; the vibration screening mechanism 3 can accelerate the screening speed of rubber rings and flash, and improve the overall efficiency of the production line.

[0026] At the top of the material receiving frame 31, a U-shaped mounting seat 34 is installed. At the top of one end of the U-shaped mounting seat 34, a screening frame 35 is threadedly installed by screws. Screening holes 36 are provided at the bottom of the screening frame 35, and the screening holes 36 provided in the screening frame 35 are adapted to the size of the rubber ring.

[0027] Specifically implemented in this way, the screening holes 36 of the screening frame 35 can be adapted and adjusted according to the size of the rubber ring to ensure that the screening process can accurately match the required product specifications, and different screening frames 35 can be replaced according to the size of the rubber ring for screening operations; by adapting the size of the screening holes 36, the rubber ring can be effectively retained at the top of the screening frame 35, and the flash can be filtered out through the screening holes 36, improving the overall quality of the product.

[0028] In order to realize the action of wind screening of the rubber ring and the flash; a wind screening mechanism 4 is provided, which includes a connecting plate 41. At the bottom of the connecting plate 41, a powerful blower 42 is installed. At the top of the connecting plate 41, an L-shaped air duct 43 is fixedly installed. The bottom air inlet end of the L-shaped air duct 43 corresponds to the air outlet end of the powerful blower 42, and the air outlet end of the L-shaped air duct 43 is arranged in parallel with one end of the U-shaped mounting seat 34.

[0029] Specifically implemented in this way, the powerful blower 42 is located at the bottom of the connecting plate 41 and can generate a strong air flow to separate the lighter flash from the rubber ring; the L-shaped air duct 43 is fixed at the top of the connecting plate 41, and its design can accurately guide the air flow direction to ensure that the wind effectively acts on the screening material; the wind generated by the powerful blower 42 can quickly blow the flash away from the rubber ring, improving the separation efficiency and reducing subsequent processing steps.

[0030] In order to realize the action of friction separation of the rubber ring and the flash; a friction separation mechanism 5 is provided, which includes a vertical plate 51. The bottoms of the two vertical plates 51 are fixedly installed on the top of the U-shaped mounting seat 34. On the opposite surfaces of the left ends of the two vertical plates 51, left horizontal frames 52 are fixedly installed. On the opposite surfaces of the middle parts of the right ends of the two vertical plates 51, sliding grooves 53 are provided, and sliding blocks 54 are slidably inserted into the inner walls of the sliding grooves 53. On the surfaces of the two sliding blocks 54, right horizontal frames 55 are fixedly installed.

[0031] Specifically implemented in this way, the left horizontal frames 52 and the right horizontal frames 55 fixed by the sliding blocks 54 are fixedly installed at the left and right ends of the two vertical plates 51 respectively, forming a friction separation area that can move relatively; the rubber ring and the flash are separated by friction, which is suitable for materials that are difficult to separate by vibration screening and wind screening; the position of the sliding block 54 in the sliding groove 53 can be adjusted, so as to change the pressure between the left horizontal frame 52 and the right horizontal frame 55 and realize the adjustment of the frictional force; friction separation is a relatively gentle separation method, which can reduce the damage to the rubber ring and maintain the quality of the product.

[0032] Both the bottom and top of the two ends of the left cross-frame 52 and the top and bottom of the two ends of the right cross-frame 55 are rotatably connected by bearings to a rotating shaft 56. A pulley 57 is fixedly installed on the arc surface of the rotating shaft 56. The inner walls of the grooves of every two pulleys 57 are drivingly connected by a friction belt 58. A limiting plate 59 is fixedly installed on the inner bottom wall of one end of the left cross-frame 52 and the inner bottom wall of one end of the right cross-frame 55. The limiting plate 59 is located inside the friction belt 58.

[0033] Specifically, implemented in this way, through the rotatable connection by bearings, the left cross-frame 52 and the right cross-frame 55 can achieve continuous rotation through the transmission of the pulleys 57 and the friction belt 58, so as to continuously frictionally separate the rubber ring and the flash; fixed on the inner bottom wall of the cross-frame and located inside the friction belt 58, it helps to maintain the stability of the belt during operation and prevent the belt from deviating or loosening.

[0034] A material receiving hopper 510 is also fixedly installed on the top of the left cross-frame 52. An adjusting plate 511 is slidably inserted into the right end of the material receiving hopper 510. The bottom of the right end of the adjusting plate 511 is fixedly installed with the top of the right cross-frame 55. A driving motor 512 is fixedly installed on the top of one end of the left cross-frame 52 and the top of the right cross-frame 55. The output end of the driving motor 512 is fixedly installed with the top of the rotating shaft 56 through a coupling.

[0035] Specifically, implemented in this way, the material receiving hopper 510 is used to guide the material into the friction separation area to ensure uniform distribution of the material; the adjusting plate 511 can be slidably adjusted to control the material flow rate entering the friction separation area to adapt to different production requirements.

[0036] By setting up the vibration screening mechanism 3, the wind screening mechanism 4 and the friction separation mechanism 5, a combination of different screening mechanisms can be achieved, enabling multi-stage screening, greatly improving the screening accuracy, ensuring thorough separation of the final rubber ring and the flash, and improving the product quality; multi-stage screening reduces the working load of a single screening mechanism and extends the service life of the equipment; the rapid screening process reduces the residence time of the material during screening and improves the overall efficiency of the production line.

[0037] Working principle: After the production of the rubber ring is completed, the whole connected by the rubber ring and the flash is taken and placed inside the material receiving hopper 510. By controlling the driving motor 512 to work and drive the two friction belts 58 to transmit and move at the same time, the relative surfaces of the two transmission belts are controlled to move in a cross motion and friction. Through friction extrusion, the rubber ring and the flash entering are frictionally separated. After the friction separation, they fall onto the top of the screening frame 35 at the bottom. By controlling the vibration motor 33 to work, the screening frame 35 is vibrated, and then the separated flash is controlled to fall and be collected through the screening holes 36, so that the rubber ring stays on the top of the screening frame 35 and is conveyed to the right under the vibration force and falls from one side. At the same time of falling, the rubber ring and the flash that are not separated cleanly are separated by the strong air blower 42 working. Then the rubber ring falls under its own weight, and the flash is far away from the falling position.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
