Description

Technical Field

[0001] This invention relates to the field of three-roll calender technology, and in particular to a finished product receiving mechanism for a three-roll calender for rubber products. Background Technology

[0002] The three-roll calender is the core equipment in rubber product manufacturing for producing rubber sheets. The calendered rubber sheets need to be collected and wound by a take-up mechanism for subsequent storage and processing. Currently, the take-up rollers of existing take-up mechanisms are typically fixed between the frame or bearing housing. This fixed installation method has two prominent problems in practical use. First, during the winding process, the winding diameter of the take-up roll continuously increases, while the take-up center position remains constant, causing the tangent point and wrap angle of the rubber sheet entering the take-up roller to continuously change. This change in geometry disrupts the stable adhesion of the rubber sheet to the roller surface, causing tension fluctuations and lateral deviation. Ultimately, this leads to quality problems such as uneven winding ends and loose, wrinkled rubber sheets. Second, the take-up roller is often fixedly connected to the frame. When a roll of rubber is finished winding, the full roll needs to be removed and replaced with a new empty roll, making disassembly and installation cumbersome. This not only consumes labor and time but also reduces the continuous operating efficiency of the entire calendering production line. Summary of the Invention

[0003] The main objective of this invention is to provide a finished product receiving mechanism for a three-roll calender for rubber products, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A finished product receiving mechanism for a three-roll calender for rubber products includes a three-roll calender. A receiving frame is fixedly installed on the front side of the three-roll calender. Two sets of triangular plates are fixedly installed on the upper side of the receiving frame. Each set of triangular plates is equipped with a control component. A receiving roller is movably arranged between the two sets of control components.

A cylinder is fixedly installed below the telescopic rod of the hydraulic cylinder. A T-shaped plate is fixedly installed at one end of the cylinder. A drive motor is fixedly installed at one end of the T-shaped plate. A transmission shaft is movably arranged on the inner side of the T-shaped plate near the front of the drive motor. A locking block is fixedly installed at one end of the transmission shaft. Synchronous pulleys are fixedly installed on both sides of the transmission shaft and the rotating shaft of the drive motor. Synchronous belts are sleeved on the outer sides of the two sets of synchronous pulleys. A connecting plate is fixedly installed on the front side of the cylinder. A half-shaft sleeve is fixedly installed on the front side of the connecting plate. A half-shaft ring is movably arranged on the inner side of the half-shaft sleeve. A ring groove is opened on the inner side of the half-shaft sleeve corresponding to the position of the half-shaft ring.

[0005] Preferably, the half-shaft sleeve has arc-shaped openings on both sides, and arc-shaped side baffles are fixedly installed at both ends of the half-shaft sleeve. A round rod is fixedly installed inside the lower side of the half-shaft ring, and connecting wheels are fixedly installed on both sides of the round rod. Anti-slip areas are provided at both ends of the half-shaft ring, and a positioning groove is provided on the upper side of the half-shaft ring. Fixing strips are fixedly installed at both ends of the connecting plate, and connecting wheels are fixedly installed at opposite ends of the upper sides of the two sets of fixing strips. A square rod is provided inside the connecting plate, and a round block is fixedly installed at the lower end of the square rod. A circular groove is provided on the lower side of the connecting plate corresponding to the position of the circular block. A return spring is sleeved between the outer circular block of the square rod and the inner wall of the circular groove. An L-shaped positioning plate is fixedly installed on the upper side of the square rod. An opening is provided on the upper side of the half-shaft sleeve corresponding to the position of the L-shaped positioning plate. An elastic band is sleeved between the two sets of connecting wheels and the two sets of connecting wheels on the same side. Several threaded holes are provided on the triangular plate frame. A fixing frame is fixedly installed at one end of the triangular plate frame corresponding to the positions of the two threaded holes. A limit block is fixedly installed on the fixing frame.

[0006] Preferably, the drive motor and synchronous belt are mounted on a control component on one side, the take-up roller is movably mounted between the half-shaft sleeves and half-shaft rings on both sides, the take-up roller has a mating interface on both sides that is compatible with the clamping block, the clamping block is triangular in shape on the upper and lower sides, and the hydraulic cylinder works in conjunction with an external infrared sensor to detect the size of the material roll on the take-up roller and extend and retract downwards.

[0007] Preferably, the drive motor's rotating shaft passes through the T-shaped plate, and the locking block is engaged with the receiving roller's interface.

[0008] Preferably, the half-shaft ring and half-shaft sleeve are circular and fitted onto the rotating shaft of the receiving roller, and the ring groove is adapted to the half-shaft ring.

[0009] Preferably, the round rod passes through the interior of the two sets of arc-shaped openings, the square rod passes through the interior of the connecting plate into the circular groove, and the round block is adapted to the circular groove.

[0010] Preferably, the L-shaped positioning plate passes through the opening and engages in the positioning groove, and the corner of the L-shaped positioning plate inserted into the positioning groove is arc-shaped.

[0011] Preferably, the elastic band is in an elastically stretched state, and the position of the limiting block corresponds to that of the circular block.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. By starting the drive motor, the connected synchronous pulley rotates, and the synchronous belt completes the power transmission. The synchronous pulley on the other side drives the transmission shaft and the clamping block to rotate synchronously, so that the take-up rollers clamped between the half-shaft sleeves and half-shaft rings on both sides rotate synchronously, thereby completing the continuous winding operation of the calendered rubber product. The clamping block and the rotating shaft of the take-up roller adopt a snap-fit ​​connection structure, which facilitates the quick disassembly, maintenance and replacement of the take-up roller by the staff. 2. As the outer diameter of the rubber material wound around the take-up roller continues to increase, the hydraulic cylinder drives the connected cylinder to move downward, which in turn drives the entire control component and the take-up roller to move downward synchronously to compensate. This can effectively avoid the problem of material cutting point position and conveying wrap angle shifting during the take-up process, greatly reduce the fluctuation of material tension, and improve the overall flatness of the rubber roll. 3. When the hydraulic cylinder push control component moves down to the preset stroke position, the round block and the limit block abut against each other, pushing the round block, square rod and L-shaped positioning plate upward as a whole and compressing the return spring, causing the L-shaped positioning plate to disengage from the positioning groove and release the locking limit on the half shaft ring; at this time, the elastic belt pulls the matching connecting wheel and round rod with its own elastic tension, driving the half shaft ring to rotate inward along the arc opening and be stored inside the half shaft sleeve, realizing the automatic opening of the half shaft sleeve on one side, which makes it easy for the operator to quickly complete the disassembly and replacement of the receiving roller; 4. After the take-up roller is replaced, the operator holds the anti-slip area on the half-shaft ring and rotates the half-shaft ring in the opposite direction, so that the positioning groove moves toward the L-shaped positioning plate. The positioning plate is pushed open by the arc-shaped guide slope at the end of the L-shaped positioning plate. After the positioning groove passes the plate surface, the return spring rebounds and pushes the L-shaped positioning plate to automatically lock into the positioning groove, completing the locking and fixing of the half-shaft ring. The fixing frame can be installed and fixed in the threaded holes at different heights by locking bolts. The working height of the whole machine can be flexibly adjusted according to the actual outer diameter requirements of the rubber material, and it is suitable for continuous winding processing of various specifications of rubber rolls.

[0017] Please see Figures 1-8An embodiment of the present invention provides a finished product receiving mechanism for a three-roll calender for rubber products, comprising a three-roll calender 1, a receiving frame 2 fixedly installed on the front side of the three-roll calender 1, two sets of triangular plate frames 3 fixedly installed on the upper side of the receiving frame 2, each set of triangular plate frames 3 being provided with a control component 4, and a receiving roller 5 movably arranged between the two sets of control components 4.

A drive motor 44 is fixedly installed. A transmission shaft 45 is movably installed on the inner side of the T-shaped plate 43 near the front of the drive motor 44. A locking block 46 is fixedly installed at one end of the transmission shaft 45. Synchronous pulleys 47 are fixedly installed on one side of the rotation shaft of the drive shaft 45 and the drive motor 44. Synchronous belts 48 are sleeved on the outer side of the two sets of synchronous pulleys 47. A connecting plate 49 is fixedly installed on the front side of the cylinder 42. A half-shaft sleeve 410 is fixedly installed on the front side of the connecting plate 49. A half-shaft ring 411 is movably installed on the inner side of the half-shaft sleeve 410. A ring groove 412 is opened on the inner side of the half-shaft sleeve 410 corresponding to the position of the half-shaft ring 411.

The take-up roller 5 has a mating interface on both sides that matches the locking block 46. The locking block 46 is triangular in shape on the upper and lower sides. The hydraulic cylinder 41 works with the external infrared sensor to detect the size of the take-up roller 5 and extends and retracts downward.

[0019] By starting the drive motor 44, the connected synchronous pulley 47 is rotated, and the synchronous belt 48 completes the power transmission. The synchronous pulley 47 on the other side drives the transmission shaft 45 and the clamping block 46 to rotate synchronously, so that the take-up roller 5, which is clamped between the half-shaft sleeves 410 and the half-shaft rings 411 on both sides, rotates synchronously, thereby completing the continuous winding operation of the calendered rubber product. The clamping block 46 and the rotating shaft of the take-up roller 5 adopt a snap-fit ​​connection structure, which facilitates the quick disassembly, maintenance and replacement of the take-up roller 5 by the staff. As the outer diameter of the rubber material wound on the take-up roller 5 continues to increase, the hydraulic cylinder 41 drives the cylinder 42 connected to it to move downward, and drives the control component 4 and the take-up roller 5 to move downward synchronously to compensate. This can effectively avoid the problem of the material cutting point position and conveying wrap angle shifting during the winding process, greatly reduce the fluctuation of material tension, and improve the overall winding flatness quality of the rubber roll.

Anti-slip areas 417 are provided at both ends of the half-shaft ring 411. A positioning groove 418 is provided on the upper side of the half-shaft ring 411. Fixing strips 419 are fixedly installed at both ends of the connecting plate 49. Connecting wheels 420 are fixedly installed at opposite ends of the upper sides of the two sets of fixing strips 419. A square rod 421 is provided inside the connecting plate 49. A round block 422 is fixedly installed at the lower end of the square rod 421. A circular groove 423 is provided on the lower side of the inner side corresponding to the circular block 422. A return spring 424 is sleeved between the outer circular block 422 and the inner wall of the circular groove 423 on the square rod 421. An L-shaped positioning plate 425 is fixedly installed on the upper side of the square rod 421. An opening 426 is provided on the upper side of the half-shaft sleeve 410 corresponding to the L-shaped positioning plate 425. An elastic band 427 is sleeved between the two sets of connecting wheels 420 and the two sets of connecting wheels 416 on the same side. Several threaded holes 428 are provided on the triangular plate frame 3. A fixing frame 429 is fixedly installed at one end of the triangular plate frame 3 corresponding to the positions of two threaded holes 428. A limit block 430 is fixedly installed on the fixing frame 429.

[0021] The round rod 415 passes through the interior of the two sets of arc-shaped openings 413, the square rod 421 passes through the interior of the connecting plate 49 into the circular groove 423, the round block 422 is adapted to the circular groove 423, the L-shaped positioning plate 425 passes through the opening 426 into the positioning groove 418 and engages, the corner of the L-shaped positioning plate 425 inserted into the positioning groove 418 is arc-shaped, the elastic band 427 is in an elastically stretched state, and the position of the limiting block 430 corresponds to that of the round block 422.

[0022] When the hydraulic cylinder 41 pushes the control component 4 down to the preset stroke position, the round block 422 and the limit block 430 abut against each other, pushing the round block 422, the square rod 421 and the L-shaped positioning plate 425 upward as a whole and compressing the return spring 424, causing the L-shaped positioning plate 425 to disengage from the positioning groove 418 and release the locking limit on the half-shaft ring 411; at this time, the elastic band 427 pulls the matching connecting wheel 416 and the round rod 415 with its own elastic tension, driving the half-shaft ring 411 to rotate inward along the arc-shaped opening 413 and be stored inside the half-shaft sleeve 410, realizing the automatic opening of the half-shaft sleeve 410 on one side, which makes it easy for the operator to quickly complete the disassembly of the receiving roller 5. Replacement; After the take-up roller is replaced, the operator holds the anti-slip area 417 on the half-shaft ring 411 and rotates the half-shaft ring 411 in the opposite direction, so that the positioning groove 418 moves toward the L-shaped positioning plate 425. The positioning plate is opened by relying on the arc-shaped guide slope at the end of the L-shaped positioning plate 425. After the positioning groove passes the plate surface, the return spring 424 rebounds and pushes the L-shaped positioning plate 425 to automatically lock into the positioning groove 418, completing the locking and fixing of the half-shaft ring; The fixing frame 429 can be installed and fixed in the threaded holes 428 at different heights by locking bolts. The working height of the whole machine can be flexibly adjusted according to the actual winding outer diameter requirements of the rubber material, and it is suitable for continuous winding processing of various specifications of rubber rolls.

[0023] Working principle: During use, the drive motor 44 is started to drive the connected synchronous pulley 47 to rotate, and the synchronous belt 48 completes the power transmission. The synchronous pulley 47 on the other side drives the transmission shaft 45 and the clamping block 46 to rotate synchronously, so that the take-up roller 5, which is clamped between the half-shaft sleeves 410 and the half-shaft rings 411 on both sides, rotates synchronously, thereby completing the continuous winding operation of the calendered rubber product. The clamping block 46 and the rotating shaft of the take-up roller 5 adopt a snap-fit ​​connection structure, which facilitates the quick disassembly, maintenance and replacement of the take-up roller 5 by the staff. As the outer diameter of the rubber material wound on the take-up roller 5 continues to increase, the hydraulic cylinder 41 drives the cylinder 42 connected to it to move down, which drives the control component 4 and the take-up roller 5 to move down synchronously to compensate. This can effectively avoid the problem of the material cutting point position and conveying wrap angle shifting during the winding process, greatly reduce the fluctuation of material tension, and improve the overall winding flatness quality of the rubber roll. When the hydraulic cylinder 41 pushes the control component 4 down to the preset stroke position, the round block 422 and the limit block 430 abut against each other, pushing the round block 422, the square rod 421 and the L-shaped positioning plate 425 upward as a whole and compressing the return spring 424, causing the L-shaped positioning plate 425 to disengage from the positioning groove 418 and release the locking limit on the half-shaft ring 411; at this time, the elastic band 427 pulls the matching connecting wheel 416 and the round rod 415 with its own elastic tension, driving the half-shaft ring 411 to rotate inward along the arc-shaped opening 413 and be stored inside the half-shaft sleeve 410, realizing the automatic opening of the half-shaft sleeve 410 on one side, which makes it easy for the operator to quickly complete the disassembly of the receiving roller 5. Replacement; After the take-up roller is replaced, the operator holds the anti-slip area 417 on the half-shaft ring 411 and rotates the half-shaft ring 411 in the opposite direction, so that the positioning groove 418 moves toward the L-shaped positioning plate 425. The positioning plate is opened by relying on the arc-shaped guide slope at the end of the L-shaped positioning plate 425. After the positioning groove passes the plate surface, the return spring 424 rebounds and pushes the L-shaped positioning plate 425 to automatically lock into the positioning groove 418, completing the locking and fixing of the half-shaft ring; The fixing frame 429 can be installed and fixed in the threaded holes 428 at different heights by locking bolts. The working height of the whole machine can be flexibly adjusted according to the actual winding outer diameter requirements of the rubber material, and it is suitable for continuous winding processing of various specifications of rubber rolls.
