Abstract
Description
Technical Field
[0001] This invention relates to a sliding butt joint type synthetic leather calendering device. Background Technology
[0002] Currently, the processing of synthetic leather often requires the use of calendering equipment, which is a device for extruding synthetic leather. In actual processing, synthetic leather is generally transported by a conveyor belt, and then rolled by pressure rollers on the upper side of the conveyor belt. However, some high-hardness particles inevitably remain in the raw materials of synthetic leather, causing excessively high local hardness. When the raw materials of synthetic leather pass through the pressure rollers, these excessively hard particles may cause local deformation of the pressure rollers, thus preventing the subsequent calendering operation from proceeding normally. Therefore, the pressure rollers need to be repaired. However, when production is urgent, there is not enough time to repair the pressure rollers, and disassembly and replacement are time-consuming and labor-intensive. Therefore, rapid repair and production resumption are required. For this reason, a rapid backup structure is needed to address this situation, which can be quickly put into production. Summary of the Invention
[0003] To address the shortcomings of the prior art, the present invention provides a sliding docking synthetic leather calendering device that can quickly switch and start up a backup structure.
[0004] To solve the above problems, the technical solution adopted by the present invention is as follows:
[0005] A sliding butt-joint type synthetic leather calendering device includes a support frame, a lower conveyor belt, a calendering assembly, and a lifting module. The lower conveyor belt is mounted on the support frame. The calendering assembly is mounted above the lower conveyor belt. The calendering assembly includes an upper pressure roller, a calendering sleeve, a connecting rod, a moving ring, an internal screw, a sliding motor, and floating blocks. A floating block is slidably engaged with the inner sides of both ends of the support frame. The lifting module is mounted on one side of the support frame and drives the floating blocks to move up and down. Both ends of the upper pressure roller are rotatably engaged with the inner sides of the floating blocks. The upper pressure roller is positioned above the lower conveyor belt. A calendering sleeve is calendered and engaged with the inner sides of each upper pressure roller. The interior of the upper pressure roller... The upper pressure roller has a through-cavity, and strip-shaped through-grooves are respectively provided on the upper sides of both ends of the upper pressure roller, which are connected to the through-cavity. A through-rod is installed on the inner side of the outer end of the calendering sleeve, and the inner ends of the two through-rods extend into the through-cavity through the strip-shaped through-grooves. A movable ring is installed between the two through-rods. An internal screw is rotatably installed in the through-cavity of the upper pressure roller. The internal screw has external threaded annular surfaces with opposing threads on both sides, and a movable ring is screwed onto each external threaded annular surface. One end of the internal screw is connected to a sliding motor, which is installed on the upper pressure roller. The internal screw drives the two calendering sleeves to slide and dock relative to each other, and they are distributed directly above the lower conveyor belt.
[0006] Furthermore, the inner circumferential surface of the calendered sleeve is provided with a wear-resistant coating.
[0007] Furthermore, the upper pressure roller is provided with rotating blocks at both ends; the floating block is provided with rotating slots on its inner side; the rotating blocks are rotatably engaged with the rotating slots.
[0008] Furthermore, one end of the upper pressure roller is provided with a drive slot; the sliding motor is installed in the drive slot; one end of the built-in screw extends into the drive slot and is connected to the sliding motor.
[0009] Furthermore, the outer surfaces of the upper pressure roller and the calendering sleeve are provided with a smooth coating.
[0010] Furthermore, the lifting module includes a top motor, an output shaft, a longitudinal screw, and a lifting block; lifting grooves are respectively provided on the inner sides of both ends of the support frame; a floating block is slidably engaged in the lifting groove; a strip-shaped slot is provided on the outer side of the lifting groove; a lifting block is installed on the outer side of the floating block, and the lifting block is slidably engaged in the strip-shaped slot. A longitudinal screw is rotatably engaged in one of the strip-shaped slots, and the longitudinal screw is threadedly connected to a lifting block. The upper end of the longitudinal screw is connected to the output shaft, and the upper end of the output shaft is connected to the top motor. The top motor is fixedly installed on one side of the upper end of the support frame.
[0011] Furthermore, drive wheels are provided on both sides of the front and rear ends of the lower conveyor belt, and a connecting rod is provided between the drive wheels. The outer sides of the drive wheels are rotatably clamped to the inner side of the support frame through rotating clamping pins. A conveyor motor is fixedly installed on the outside of one side of the support frame, and the inner side of the conveyor motor is connected to the outer end of a rotating clamping pin through a rotating shaft.
[0012] The beneficial effects of this invention are as follows:
[0013] This invention first calenders the synthetic leather on the upper side of the lower conveyor belt through the middle section of the upper pressure roller. When the outer surface of the upper pressure roller breaks or deforms, the floating block and the upper pressure roller can be moved upward by the lifting module. Then, the built-in screw is driven to rotate by the sliding motor, and the built-in screw drives the moving ring to move relative to each other. In this way, the two calendering sleeves slide and dock relative to each other and are distributed directly above the lower conveyor belt. Thus, the two calendering sleeves form a pressure roller structure. Finally, the floating block and the upper pressure roller are driven to move downward by the lifting module. In this way, the synthetic leather on the upper side of the lower conveyor belt is calendered through the two docked calendering sleeves, realizing rapid switching and suitable for emergency production.

The upper ends of the upper pressure roller 31 are respectively provided with strip-shaped through-hole grooves, which communicate with the through-hole cavity 311. A through-hole rod 33 is installed on the inner side of the outer end of the calendering sleeve 32, one on the top and one on the bottom. The inner ends of the two through-hole rods 33 extend into the through-hole cavity 311 through the strip-shaped through-hole grooves. A movable ring 34 is installed between the two through-hole rods 33. An internal screw 35 is rotatably installed in the through-hole cavity 311 of the upper pressure roller 31. The internal screw 35 has externally threaded annular surfaces with opposing threads on both sides. A movable ring 34 is threaded onto each of the externally threaded annular surfaces. One end of the internal screw 35 is connected to a sliding motor 36, which is mounted on the upper pressure roller 31. The internal screw 35 drives the two calendering sleeves 32 to slide and connect relative to each other, positioning them directly above the lower conveyor belt 2.
[0022] like Figures 1 to 6 As shown, to reduce friction, the inner circumference of the calendering sleeve 32 is further provided with a wear-resistant coating. To facilitate stable rotation of the upper pressure roller 31, rotating blocks 313 are provided at both ends of the upper pressure roller 31; rotating grooves are provided on the inner sides of the floating blocks 37; the rotating blocks 313 are rotatably engaged with the rotating grooves. Furthermore, a drive slot 312 is provided at one end of the upper pressure roller 31; the sliding motor 36 is installed within the drive slot 312; one end of the built-in screw 35 extends into the drive slot 312 and connects to the sliding motor 36. Furthermore, a smooth coating is provided on the outer surfaces of the upper pressure roller 31 and the calendering sleeve 32.
[0023] like Figures 1 to 6 As shown, in order to achieve the up-and-down driving of the floating block 37, the lifting module 4 further includes a top motor 41, an output shaft 43, a longitudinal screw 44, and a lifting block 42; the inner sides of both ends of the support frame 1 are respectively provided with lifting grooves 11; a floating block 37 is slidably engaged in the lifting grooves 11; a strip-shaped slot 12 is provided on the outer side of the lifting grooves 11; a lifting block 42 is installed on the outer side of the floating block 37, and the lifting block 42 is slidably engaged in the strip-shaped slot 12.

[0025] This invention first uses the middle section of the upper pressure roller 31 to calender the synthetic leather on the upper side of the lower conveyor belt 2. When the outer surface of the upper pressure roller 31 breaks or deforms, the floating block 37 and the upper pressure roller 31 can be driven to move upward by the lifting module 4. Then, the built-in screw 35 is driven to rotate by the sliding motor 36, and the built-in screw 35 drives the moving ring 34 to move relative to each other.
