Description

Technical Field

[0001] This invention relates to the field of rubber roller pressing machines, and more particularly to a pneumatic rubber roller pressing machine. Background Technology

[0002] Existing rubber roller pressing equipment consists of a frame, motor, transmission gears, upper and lower pressure rollers, pull arm, limit rod, and pneumatic-hydraulic conversion booster cylinder. Besides older pressing machines that use a counterweight to adjust the downward pressure (a relatively primitive method), existing equipment typically uses a pneumatic-hydraulic conversion booster cylinder as the downward pressure source. This structure is complex, involves multiple steps in the pneumatic-hydraulic conversion process, is prone to oil leakage, has unclear operation, and pressure adjustment is not always smooth. Therefore, we propose a pneumatic rubber roller pressing machine. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the background art by proposing a pneumatic rubber roller pressing machine.

[0004] The technical solution of the present invention: A pneumatic rubber roller pressing machine includes a machine body, a motor fixedly installed inside the machine body, a first belt shaft fixedly installed at one end of the motor, a lower pressure roller seat fixedly installed on the machine body, a first lower pressure roller and a second lower pressure roller rotatably installed on the lower pressure roller seat, a transmission mechanism provided between the first lower pressure roller and the second lower pressure roller, a second belt shaft fixedly installed at one end of the first lower pressure roller, a conveyor belt installed between the second belt shaft and the first belt shaft, and an upper pressure roller control mechanism and a position adjustment mechanism installed on the machine body.

[0005] Preferably, the transmission mechanism includes a main gear fixedly installed at one end of the first lower pressure roller, a driven gear fixedly installed at one end of the second lower pressure roller, and a transition gear rotatably installed on one side of the lower pressure roller seat. The transition gear is meshed with the main gear and the driven gear, respectively.

[0006] Preferably, the upper pressure roller control mechanism includes a first slide groove formed inside the machine body and a second slide groove formed on the upper surface of the machine body. A cylinder seat is slidably installed in the first slide groove, and a support plate is slidably installed in the second slide groove.

[0007] Preferably, an upper pressure roller seat is fixedly installed on the support plate, an upper pressure roller support arm is rotatably installed on the upper pressure roller seat, and an upper pressure roller is installed on the upper pressure roller support arm.

[0008] Preferably, a cylinder is mounted on the cylinder seat, a connecting rod is connected to the cylinder, a support arm seat is rotatably mounted on the upper end of the connecting rod, the upper pressure roller support arm is fixedly mounted on the support arm seat, a first through-hole is opened on the machine body, the connecting rod passes through the first through-hole, and a limit rod is installed between the upper pressure roller support arm and the support plate.

[0009] Preferably, the position control mechanism includes a second opening on the lower side of the second slide groove, and an L-shaped connecting plate passing through the second opening is fixedly installed between the cylinder seat and the support plate.

[0010] Preferably, a connecting seat is fixedly installed on one side of the L-shaped connecting plate, and an adjusting connecting column is rotatably engaged on one side of the connecting seat.

[0011] Preferably, a screw is fixedly welded to one end of the regulating connecting column, a screw hole is opened on one side of the machine body, the screw passes through the screw hole and is threadedly connected to the screw hole, and a rotating handle is fixedly connected to one end of the screw.

[0012] Preferably, a switching motor is fixedly installed inside the machine body, and a telescopic rod is fixedly installed at the output end of the switching motor.

[0013] Preferably, a first gear is fixedly installed at one end of the telescopic rod, and a second gear is fixedly installed on the adjusting connecting column. The second gear meshes with the first gear. A first annular groove is opened on one side of the first gear, and a second annular groove is opened on one side of the second gear. A first retaining bead is slidably locked in the first annular groove, and a second retaining bead is slidably locked in the second annular groove. A C-shaped connecting rod is rotatably locked between the second retaining bead and the first retaining bead.

[0014] Compared with existing technologies, the beneficial effects of this invention are:

[0015] (1): This application can not only adjust the up and down position of the upper pressure roller so that the upper pressure roller can press the rubber roller into a circle without pressing it too low, but also adjust the horizontal position of the upper pressure roller by sliding so that when the rubber roller is pressed into a circle, the upper pressure roller is located in the middle above the first lower pressure roller and the second lower pressure roller. The three form an isosceles triangle, so that when the rubber roller is pressed into a circle, it is pressed down from directly above by the upper pressure roller, so that the pressure of the rubber roller and the two first lower pressure rollers and the second lower pressure roller is balanced, thereby improving the pressing quality of the rubber roller. The position of the upper pressure roller can be adjusted according to the rubber roller of different sizes, so as to adapt to the processing of rubber rollers of different sizes. Furthermore, a large-diameter cylinder is used as the downward pressure force source, eliminating the gas-liquid conversion booster cylinder as the downward pressure force source, avoiding the unstable factors of the downward pressure force source generated when the air source is input into the booster cylinder. The structure is simple and the pressure adjustment is intuitive.

[0016] (2): This application drives the screw to rotate by rotating the handle, and drives the screw to move by the action of the screw and the screw hole, which in turn drives the L-shaped connecting plate to move. This allows the position of the cylinder seat and the support plate to be controlled at the same time, and thus the lateral position of the upper pressure roller can be controlled conveniently, making operation convenient.

[0017] (3): This application drives the telescopic rod and the first gear to rotate by switching the motor, and the first gear drives the second gear to rotate, which can drive the screw to rotate, thereby adjusting the position of the upper pressure roller. This allows for human-machine switching control, which can be both manual and intelligent motor control. The first and second locking balls at both ends of the C-shaped connecting rod are respectively locked in the first and second annular grooves of the first and second gears. In this way, the first and second gears can not only mesh, but also will not separate when moving horizontally. Attached Figure Description

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1-5As shown, the present invention proposes a pneumatic rubber roller pressing machine, comprising a machine body 1, a motor 5 fixedly installed inside the machine body 1, a first belt shaft 6 fixedly installed at one end of the motor 5, a lower pressure roller seat 2 fixedly installed on the machine body 1, a first lower pressure roller 3 and a second lower pressure roller 4 rotatably installed on the lower pressure roller seat 2, a transmission mechanism provided between the first lower pressure roller 3 and the second lower pressure roller 4, a second belt shaft 7 fixedly installed at one end of the first lower pressure roller 3, a conveyor belt 8 installed between the second belt shaft 7 and the first belt shaft 6, an upper pressure roller control mechanism and a position adjustment mechanism installed on the machine body 1, the transmission mechanism including a main gear 9 fixedly installed at one end of the first lower pressure roller 3, a driven gear 11 fixedly installed at one end of the second lower pressure roller 4, and a transition gear 10 rotatably installed on one side of the lower pressure roller seat 2, the transition gear 10 being respectively connected to the main gear 9. The upper pressure roller control mechanism includes a first slide groove 12 inside the machine body 1 and a second slide groove 18 on the upper surface of the machine body 1. A cylinder seat 13 is slidably installed in the first slide groove 12, and a support plate 19 is slidably installed in the second slide groove 18. An upper pressure roller seat 20 is fixedly installed on the support plate 19. An upper pressure roller support arm 21 is rotatably installed on the upper pressure roller seat 20. An upper pressure roller 22 is installed on the upper pressure roller support arm 21. A cylinder 14 is installed on the cylinder seat 13. A connecting rod 15 is connected to the cylinder 14. A support arm seat 17 is rotatably installed at the upper end of the connecting rod 15. The upper pressure roller support arm 21 is fixedly installed on the support arm seat 17. A first through-hole 16 is opened on the machine body 1. The connecting rod 15 passes through the first through-hole 16. A limit rod 23 is installed between the upper pressure roller support arm 21 and the support plate 19.

[0027] In this embodiment, when using the invention, the rubber roller is placed between the first lower pressure roller 3 and the second lower pressure roller 4. The upper and lower positions of the limiting rod 23 are adjusted, and the cylinder seat 13 and the support plate 19 are slid to adjust the position of the upper pressure roller 22. This ensures that when the upper pressure roller 22 presses down, it can round the rubber roller without pressing it too low. The upper pressure roller 22 is located directly above and in the middle of the first lower pressure roller 3 and the second lower pressure roller 4. The motor 5 is started, and the first lower pressure roller 3 is driven by the conveyor belt 8. The second lower pressure roller 4 is driven by the main gear 9, the transition gear 10, and the driven gear 11. The air source is connected, and the working air pressure is preset according to the rubber roller rounding condition. The machine is started, and the cylinder 14 pulls the upper pressure roller 22 down through the connecting rod 15 to round the rubber roller. The invention can not only adjust the upper and lower positions of the upper pressure roller 22, but also... When the upper pressure roller 22 presses down, it can press the rubber roller into a round shape without pressing it too low. The horizontal position of the upper pressure roller 22 can be adjusted by sliding, so that when the rubber roller is being pressed into a round shape, the upper pressure roller 22 is located directly above the first lower pressure roller 3 and the second lower pressure roller 4, forming an isosceles triangle. This allows the rubber roller to press down from directly above with the upper pressure roller 22 during the pressing process, maintaining a balance of pressure between the rubber roller and the two first lower pressure rollers 3 and the second lower pressure roller 4, thereby improving the rounding quality of the rubber roller. Furthermore, the position of the upper pressure roller 22 can be adjusted according to different sizes of rubber rollers, thus adapting to the processing of rubber rollers of different sizes. A large-diameter cylinder is used as the downward pressure force source, eliminating the need for a gas-liquid conversion booster cylinder as the downward pressure force source, avoiding the instability of the downward pressure force source caused by the input of air into the booster cylinder. The structure is simple and the pressure adjustment is intuitive.

[0028] Example 2

[0029] like Figure 1-5 As shown, the pneumatic rubber roller pressing machine proposed in this invention, compared with Embodiment 1, further includes: a position control mechanism including a second opening 24 opened on the lower side of the second slide groove 18, an L-shaped connecting plate 25 that passes through the second opening 24 is fixedly installed between the cylinder seat 13 and the support plate 19, a connecting seat 26 is fixedly installed on one side of the L-shaped connecting plate 25, an adjusting connecting column 30 is rotatably engaged on one side of the connecting seat 26, a screw 28 is fixedly welded to one end of the adjusting connecting column 30, a screw hole 27 is opened on one side of the machine body 1, the screw 28 passes through the screw hole 27 and is threadedly connected to the screw hole 27, and a rotating handle 29 is fixedly connected to one end of the screw 28.

[0030] In this embodiment, rotating the handle 29 drives the screw 28 to rotate, and the screw 28 moves through the action of the screw hole 27, which in turn moves the L-shaped connecting plate 25. This allows for simultaneous control of the positions of the cylinder seat 13 and the support plate 19, thereby enabling convenient control of the lateral position of the upper pressure roller 22, making operation convenient.

[0031] Example 3

[0032] like Figure 1-5As shown, the pneumatic rubber roller pressing machine proposed in this invention, compared with Embodiment 1 or Embodiment 2, further includes: a switching motor 32 fixedly installed inside the machine body 1, a telescopic rod 33 fixedly installed at the output end of the switching motor 32, a first gear 34 fixedly installed at one end of the telescopic rod 33, a second gear 31 fixedly installed on the regulating connecting column 30, the second gear 31 meshing with the first gear 34, a first annular groove 35 opened on one side of the first gear 34, a second annular groove 36 opened on one side of the second gear 31, a first retaining bead 37 slidably locked in the first annular groove 35, a second retaining bead 38 slidably locked in the second annular groove 36, and a C-shaped connecting rod 39 rotatably locked between the second retaining bead 38 and the first retaining bead 37.

[0033] In this embodiment, the telescopic rod 33 and the first gear 34 are rotated by the switching motor 32, and the first gear 34 drives the second gear 31 to rotate, which in turn drives the screw 28 to rotate, thereby adjusting the position of the upper pressure roller 22. This allows for human-machine switching control, which can be performed manually or by intelligent motor control. The first locking ball 37 and the second locking ball 38, which are rotatably engaged at both ends of the C-shaped connecting rod 39, are respectively rotatably engaged in the first annular groove 35 and the second annular groove 36 of the first gear 34 and the second gear 31. In this way, the first gear 34 and the second gear 31 can not only mesh, but also will not separate when moving horizontally.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
