Description

Technical Field

[0001] This utility model relates to the field of calendering molding machine technology, specifically a calendering molding machine for rubber sealing rings. Background Technology

[0002] As a key basic component, rubber seals are widely used in industries such as machinery, automobiles, aerospace, and energy. Their performance directly affects the sealing effect and service life of equipment. Among many manufacturing processes, calendering technology has become the core link in rubber seal manufacturing due to its efficient and continuous production characteristics. This process mainly uses one or more sets of counter-rotating heated rollers to extrude and stretch the rubber material, forming a semi-finished seal with a predetermined cross-sectional shape and thickness.

[0003] In the calendering process of natural rubber sheets, the diffusion of dust and volatiles poses a dual challenge. On the one hand, the dried rubber compound releases a large number of micron-sized dust particles under roller extrusion. These particles form an explosive mixture around the equipment, posing a risk of combustion and explosion when the concentration exceeds 50 g / m³. On the other hand, volatile organic compounds (such as plasticizers and antioxidants) generated during the high-temperature calendering process permeate the workshop, and long-term inhalation will harm the respiratory health of workers. Existing calendering equipment generally lacks an integrated collection system. Therefore, we provide a rubber sealing ring calendering machine to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a rubber sealing ring calendering machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rubber sealing ring calendering machine, comprising a machine body, and further comprising:

[0007] The pressure roller transmission mechanism includes two first rollers and second rollers rotatably arranged inside the machine body for extruding the rubber material. The first rollers and second rollers are driven by a gear mechanism. When the first rollers rotate, the gear mechanism drives the second rollers to rotate synchronously in the opposite direction.

[0008] The dust absorption structure includes multiple dust suction nozzles disposed inside the machine body and above the first roller. The dust suction nozzles are used to absorb dust and volatiles released during the calendering process of the rubber compound.

[0009] A negative pressure extraction device includes a dust collection box fixed on the body, the dust collection box being connected to multiple suction nozzles via an air extraction pipe, and a negative pressure extraction mechanism being provided on the body for drawing a vacuum inside the dust collection box, thereby creating a negative pressure suction force at the suction nozzles.

[0010] As described above, a rubber sealing ring calendering machine is provided with a motor on the machine body. The output end of the motor is connected to the first roller through a coupling to drive the first roller to rotate.

[0011] A rubber sealing ring extrusion molding machine as described above: the gear mechanism includes a first gear fixed at one end of a first roller and a second gear fixed at one end of a second roller, wherein the first gear meshes with the second gear.

[0012] As described above, a rubber sealing ring calendering machine has multiple dust suction nozzles evenly spaced and linearly distributed above the first roller.

[0013] As described above, a rubber sealing ring calendering machine includes a negative pressure suction mechanism comprising a piston cylinder fixed to the machine body, a piston being movably engaged within the piston cylinder, and a piston cooperating with a first roller via a linkage mechanism. When the first roller rotates, it drives the piston to move up and down reciprocally within the piston cylinder. The piston cylinder is provided with an exhaust pipe and an air inlet pipe communicating with a dust collection box. The dust collection box is provided with a filter structure for filtering the dust and volatiles extracted by the suction nozzle.

[0014] As described above, a rubber sealing ring calendering machine includes a linkage mechanism comprising a turntable fixed to one end of a first roller and a piston rod movably inserted into the piston cylinder. One end of the piston rod is fixed to a piston, and a swing arm is provided between the piston rod and the turntable. The two ends of the swing arm are respectively hinged to the turntable and the piston rod.

[0015] A rubber sealing ring calendering machine as described above: the filter structure includes an annular partition fixed inside the dust collection box, a filter cylinder with a top opening is provided inside the annular partition, the air extraction pipe passes through the filter cylinder and extends to the bottom of the filter cylinder, and the air inlet pipe extends into the inner cavity of the filter cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the rubber material is squeezed and stretched between two relatively rotating first and second rollers to form a semi-finished sealing ring with a predetermined cross-sectional shape and thickness. Multiple dust suction nozzles are set above the first roller to absorb the dust and volatiles released during the calendering process of the rubber material. The air containing dust and volatiles will enter the dust collection box and be filtered by the filter cartridge inside the dust collection box. Finally, the filtered air will enter the piston cylinder through the air inlet pipe and then be discharged to the outside through the exhaust pipe.

[0017] Therefore, this invention can promptly absorb and purify the large amount of micron-sized dust particles released by the dried rubber material under the extrusion of the rollers during the calendering process before discharging them. On the one hand, it avoids the risk of combustion and explosion caused by particle aggregation. On the other hand, it avoids the problem of volatile organic compounds generated during the high-temperature calendering process spreading in the workshop and causing long-term inhalation to harm the respiratory health of workers.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1-6 As one embodiment of this utility model, a rubber sealing ring calendering machine includes a machine body 1, and further includes:

[0027] The pressure roller transmission mechanism includes two first rollers 3 and second rollers 4 rotatably arranged inside the machine body 1 for extruding the rubber material. The first rollers 3 and second rollers 4 are driven by a gear mechanism. When the first rollers 3 rotate, the gear mechanism drives the second rollers 4 to rotate synchronously in the opposite direction.

[0028] The dust absorption structure includes multiple dust suction nozzles 19 disposed inside the machine body 1 and above the first roller 3. The dust suction nozzles 19 are used to absorb dust and volatiles released during the calendering process of the rubber compound.

[0029] The negative pressure extraction device includes a dust collection box 15 fixed on the body 1. The dust collection box 15 is connected to multiple suction nozzles 19 through an air extraction pipe 18. The body 1 is equipped with a negative pressure extraction mechanism, which is used to evacuate the inside of the dust collection box 15, thereby forming a negative pressure suction force at the suction nozzles 19.

[0030] In this embodiment, during use, the machine body 1 has feeding ports 2 on both the front and back sides. The rubber material enters the machine body 1 through one feeding port 2 and is squeezed and stretched between two relatively rotating first rollers 3 and second rollers 4 to form a semi-finished sealing ring with a predetermined cross-sectional shape and thickness. Then, it is output from the machine body 1 through the other feeding port 2. During the calendering process, multiple dust suction nozzles 19 are set above the first roller 3, and a negative pressure extraction mechanism is set on the machine body 1. The negative pressure extraction mechanism is used to evacuate the dust collection box 15, thereby forming a negative pressure suction force at the dust suction nozzles 19. The dust suction nozzles 19 are used to absorb the dust and volatiles released during the calendering process of the rubber material. The air containing dust and volatiles will enter the dust collection box 15 through the air extraction pipe 18.

[0031] As a further embodiment of this utility model, a motor 5 is provided on the machine body 1, and the output end of the motor 5 is connected to the first roller 3 through a coupling to drive the first roller 3 to rotate.

[0032] In this embodiment, the motor 5 is electrically connected to an external power source via a wire, and starting the motor 5 can drive the first roller 3 to rotate continuously.

[0033] As a further embodiment of this utility model, the gear mechanism includes a first gear 6 fixed at one end of the first roller 3 and a second gear 7 fixed at one end of the second roller 4, wherein the first gear 6 meshes with the second gear 7.

[0034] In this embodiment, when the first roller 3 rotates, it drives the first gear 6 to rotate. The first gear 6 meshes with the second gear 7, and the rotation of the first gear 6 drives the second gear 7 to rotate in the opposite direction, thereby driving the second roller 4 to rotate in the opposite direction.

[0035] As a further embodiment of this utility model, multiple suction nozzles 19 are evenly spaced and linearly distributed above the first roller 3.

[0036] In this embodiment, multiple suction nozzles 19 are used to absorb the dust and volatiles released during the calendering process of the rubber compound.

[0037] As a further embodiment of this utility model, the negative pressure suction mechanism includes a piston cylinder 8 fixed on the body 1, a piston 10 is movably engaged inside the piston cylinder 8, and the piston 10 is connected to the first roller 3 through a linkage mechanism. When the first roller 3 rotates, it will drive the piston 10 to move up and down reciprocally inside the piston cylinder 8. The piston cylinder 8 is provided with an exhaust pipe 13 and an air inlet pipe 14 connected to the dust collection box 15. The dust collection box 15 is provided with a filter structure for filtering the dust and volatiles extracted by the suction nozzle 19.

[0038] In this embodiment, the piston 10 and the first roller 3 are connected by a linkage mechanism. When the first roller 3 rotates, it drives the piston 10 to move up and down in the piston cylinder 8. When the piston 10 moves up and down in the piston cylinder 8, it works with the air inlet pipe 14 to repeatedly draw air from the inside of the dust collection box 15 into the piston cylinder 8, so that a negative pressure is formed inside the dust collection box 15. Then, with the help of the air extraction pipe 18 and the dust suction nozzle 19, the dust and volatiles released during the calendering of the rubber material are absorbed into the dust collection box 15. The dust collection box 15 is equipped with a filter structure to filter the dust and volatiles drawn by the dust suction nozzle 19. The filtered air is drawn into the piston cylinder 8 and finally discharged to the outside through the exhaust pipe 13.

[0039] It should be noted that one-way valves are installed on the exhaust pipe 13 and the intake pipe 14 respectively. The one-way valve on the intake pipe 14 only allows the gas inside the dust collection box 15 to enter the piston cylinder 8 in one direction through the intake pipe 14, and the one-way valve on the exhaust pipe 13 only allows the gas inside the piston cylinder 8 to be discharged outward in one direction through the exhaust pipe 13.

[0040] As a further embodiment of this utility model, the linkage mechanism includes a turntable 11 fixed at one end of the first roller 3 and a piston rod 9 movably inserted into the piston cylinder 8. One end of the piston rod 9 is fixed to the piston 10, and a swing arm 12 is provided between the piston rod 9 and the turntable 11. The two ends of the swing arm 12 are respectively hinged to the turntable 11 and the piston rod 9.

[0041] In this embodiment, when the first roller 3 rotates, it will drive the turntable 11 to rotate synchronously. When the turntable 11 rotates, the two ends of the swing arm 12 are respectively hinged to the turntable 11 and the piston rod 9, which will drive the swing arm 12 to swing and pull the piston rod 9 to move up and down, thereby driving the piston 10 to move up and down inside the piston cylinder 8.

[0042] As a further embodiment of this utility model, the filter structure includes an annular partition 17 fixed inside the dust collection box 15, a filter cylinder 16 with a top opening is provided inside the annular partition 17, an air extraction pipe 18 passes through the filter cylinder 16 and extends to the bottom of the filter cylinder 16, and an air inlet pipe 14 extends into the inner cavity of the filter cylinder 16.

[0043] In this embodiment, the air inlet pipe 14 extends into the inner cavity of the filter cartridge 16, thereby drawing air from the inside of the dust collection box 15 to the outside and creating a negative pressure inside the dust collection box 15. The air extraction pipe 18 passes through the filter cartridge 16 and extends to the bottom of the filter cartridge 16. That is, the air containing dust and volatiles drawn by the suction nozzle 19 will first enter the space formed by the filter cartridge 16, the annular partition 17, and the dust collection box 15. After that, the air will be filtered and purified by the filter cartridge 16 before entering the inner cavity of the filter cartridge 16. The air inlet pipe 14 will draw the air after the filter layer outward. In addition, an inspection door is installed on the dust collection box 15, and a dust discharge pipe 20 is installed at the bottom of the dust collection box 15. Opening the inspection door facilitates the regular cleaning and maintenance of the internal filter cartridge 16 to remove impurities adhering to it.

[0044] During use, the machine body 1 has feeding ports 2 on both the front and back. The rubber material enters the machine body 1 through one feeding port 2 and is squeezed and stretched between two relatively rotating first rollers 3 and second rollers 4 to form a semi-finished sealing ring with a predetermined cross-sectional shape and thickness. It is then output from the machine body 1 through the other feeding port 2. During the calendering process, multiple dust suction nozzles 19 are set above the first roller 3. The machine body 1 is equipped with a negative pressure extraction mechanism. The negative pressure extraction mechanism is used to evacuate the dust collection box 15, thereby forming a negative pressure suction force at the dust suction nozzles 19. The dust suction nozzles 19 are used to absorb the dust and volatiles released during the calendering process of the rubber material. The air containing dust and volatiles will enter the dust collection box 15 and be filtered by the filter cartridge 16 inside the dust collection box 15. Finally, the filtered air enters the piston cylinder 8 through the air inlet pipe 14 and is discharged to the outside through the exhaust pipe 13.

[0045] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
