Description

Technical Field

[0001] The present application belongs to the technical field of boot cover processing equipment, and more specifically, relates to a boot cover surface processing trolley. Background Art

[0002] Shoe filter press is a common filter pressing and dehydration process in papermaking, which is usually carried out using a shoe filter press. The shoe filter press includes a set of opposing shoe rollers and counter rollers, with a pressure zone formed between the shoe rollers and counter rollers. A flexible shoe cover is set on the shoe roller, and the rotation of the shoe cover drives the wet paper to pass through the pressure zone, so that the wet paper is squeezed and dehydrated. Since the wet paper and the shoe cover are attached together during the squeezing process, the flatness and roughness of the shoe cover surface are required to be high.

[0003] The current production of boot covers generally involves coating the surface of the base fabric with polyurethane material first, and then processing the surface of the boot cover by turning and grinding after the polyurethane material is cured to ensure that the surface of the boot cover is flat and smooth. During turning and grinding, the flexible boot cover is continuously rotated on a pair of parallel support rollers, and the turning tool and grinding wheel are against the surface of the boot cover supported by the support rollers, thereby turning and grinding the surface of the boot cover.

[0004] In actual production, due to the different types and sizes of boot sleeves produced, the support rollers required are different, or the support roller models purchased by the company at different times are different, resulting in many support rollers with different diameters. The current boot sleeve surface processing trolley is usually designed for support rollers of one diameter. For multiple support rollers of different diameters, different boot sleeve surface processing trolleys must be matched respectively, resulting in equipment duplication and high cost.

[0019] The boot cover surface processing trolley is also provided with a locking mechanism for fixing the position of the initial positioning platform.

[0020] In certain embodiments, the switchable linkage mechanism includes an upper section rod, a middle section rod, a lower section rod and a switching drive; the front end of the upper section rod is hinged to the measuring pressure arm, and the rear end is hinged to the front end of the middle section rod, the front end of the lower section rod is hinged to the rear end of the middle section rod, and the rear end is hinged to the fixed arm; the rear end of the upper section rod and the front end of the lower section rod are respectively provided with a slot and a tenon; the switching drive drives the middle section rod to rotate relative to the upper section rod or the lower section rod so that the rear end of the upper section rod is merged or separated from the front end of the lower section rod, and when the rear end of the upper section rod is merged with the front end of the lower section rod, the slot is engaged with the tenon to achieve relative fixation of the upper section rod and the lower section rod in the directions at both ends.

[0021] In some embodiments, the mounting frame includes a base plate and a column disposed on the base plate, the measuring pressure arm is hinged to the column, and the upper section rod and the lower section rod are combined and tilted toward the column;

[0022] The locking mechanism includes at least two top abutment grooves provided on the column, and the lower section rod tilts toward each of the top abutment grooves in a free state; each of the top abutment grooves has different upper and lower positions and corresponds to support rollers of different diameters. When the initial positioning platform slides to match a support roller of a certain diameter, the front end of the lower section rod is separated from the rear end of the upper section rod, and the lower section rod tilts freely so that the front end enters the corresponding top abutment groove.

[0023] In some embodiments, the measuring pressure arm is hinged to the column, and a cylinder is provided between the swing end of the measuring pressure arm and the top end of the column, and the cylinder drives the measuring pressure arm to swing.

[0043] Please also read Figures 1 to 3 The present invention provides a boot surface processing trolley, which includes a movable base, a lifting mechanism, an initial positioning platform, a folding arm mechanism, a measuring pressure arm, a linkage mechanism, a measuring seat and a fine-tuning structure.

[0044] The movable base is suitable for moving in a direction parallel to the axis of the support roller. The lifting mechanism is arranged on the movable base and has a lifting mounting frame. The initial positioning platform is slidably arranged on the mounting frame in the direction of approaching and moving away from the support roller. The folding arm mechanism includes a fixed arm and a movable arm hinged to each other in an inverted V shape, the fixed arm is hinged to the mounting frame, and the movable arm is hinged to the initial positioning platform; when the fixed arm and the movable arm are opened, the movable arm drives the initial positioning platform to approach the support roller, and when the fixed arm and the movable arm are folded, the movable arm drives the initial positioning platform away from the support roller. One end of the measuring pressure arm is hinged to the mounting frame, and the other end swings toward or away from the support roller. The two ends of the linkage mechanism are respectively hinged to the measuring pressure arm and the fixed arm. When the measuring pressure arm swings toward the support roller, the fixed arm and the movable arm are driven to open through the linkage mechanism, and when the measuring pressure arm swings away from the support roller, the fixed arm and the movable arm are driven to close through the linkage mechanism. The measuring seat is provided with guide wheels at both ends and a surface measuring unit in the middle; the measuring seat is hinged to the swing end of the measuring pressure arm, and is suitable for pressing the two guide wheels against the surface of the boot sleeve on the periphery of the support roller through the swing of the measuring pressure arm, and allowing the surface measuring unit to detect the distance of the boot sleeve surface. The fine-tuning structure is suitable for fixing the turning tool or grinding wheel; the fine-tuning structure is provided on the initial positioning platform, and is suitable for fine-tuning the turning tool or grinding wheel relative to the initial positioning platform in the direction close to or away from the support roller.

[0045] When in use, the boot surface processing trolley is set close to the support roller, and the moving direction of the movable base is parallel to the axial direction of the support roller. The entire turning process includes two stages: measurement preparation and turning.

[0046] Measurement preparation process: The measuring pressure arm descends so that the two guide wheels of the measuring seat are against the surface of the boot sleeve on the periphery of the support roller, so that the coordinates of three points on the support roller can be roughly determined by the two guide wheels and the surface measurement unit, and then the approximate diameter of the support roller can be calculated. By comparing the calculated approximate diameter with several known diameters of the support roller, the exact diameter and axial position of the support roller can be determined. Then, according to the exact diameter and axial position of the support roller, the turning tool on the initial positioning table can be raised and lowered to a suitable turning height through the lifting and lowering of the lifting mechanism; during the lifting and lowering process of the lifting mechanism, the measuring pressure arm is continuously swung downward to keep the two guide wheels pressed on the surface of the boot sleeve on the periphery of the support roller. At the same time, the measuring pressure arm presses down the fixed arm through the linkage mechanism, so that the fixed arm and the movable arm are opened, driving the initial positioning table close to the support roller to achieve the approximate positioning of the turning tool; finally, the turning tool is fine-tuned through the fine-tuning structure to adjust the turning thickness, and turning can be carried out normally.

[0047] Turning process: The measuring pressure arm keeps the two guide wheels pressed against the surface of the boot sleeve on the periphery of the support roller, so that the surface measurement unit detects the distance of the boot sleeve surface to determine whether the thickness of the boot sleeve meets the standard, and then further fine-tunes the turning tool through the fine-tuning structure to ensure that the thickness of the boot sleeve meets the requirements.

[0048] Compared with the prior art, the boot surface processing trolley of the embodiment of the present application determines the diameter and the axis position of the support roller by detecting the two guide wheels of the measuring seat and the surface measuring unit, without manual intervention, and has a high degree of automation; and the measuring pressing arm drives the folding arm mechanism through the linkage mechanism while performing the measuring action, so that the initial positioning table can simultaneously complete the rough adjustment action of the front and rear positions of the turning tool, thereby greatly shortening the time of the overall measurement preparation process and improving production efficiency;

[0049] The measuring pressure arm drives the folding arm mechanism, which in turn pushes the initial positioning table to slide to complete the coarse adjustment of the front and rear positions of the turning tool. After that, the fine-tuning structure is used to accurately adjust the front and rear positions of the turning tool, which not only ensures the overall adjustment stroke of the turning tool, but also ensures the final adjustment accuracy.

[0050] During implementation, it is necessary to determine the specific parameters of each part according to the support rollers that need to be adapted. For example, the lifting range of the mounting frame and the angle of the tool or grinding wheel are determined according to the diameter of different support rollers, the axis height of various support rollers in use, and the angle of the tool or grinding wheel required for cutting. The required range of forward and backward movement of the initial positioning table is determined by the diameter of different support rollers and the horizontal position of the axis of various support rollers in use. By reasonably setting the movement relationship between the measuring pressure arm, the folding arm mechanism, and the linkage mechanism, the actual forward and backward movement range of the initial positioning table driven by the measuring pressure arm can be made to meet the required range as much as possible. The parts that are difficult to meet can be supplemented by the adjustment stroke of the fine-tuning structure.

[0051] The fine-tuning structure can be installed with a turning tool or a grinding wheel for turning or grinding the surface of the boot sleeve. Specifically, the fine-tuning structure can adopt an existing turning tool clamping structure, or set a fixed platform to install the grinding wheel and its power mechanism. In one embodiment, two sets of initial positioning tables, folding arm mechanisms, measuring pressure arms, linkage mechanisms, measuring seats and fine-tuning structures can be set on the mounting frame of the lifting mechanism of the same boot sleeve surface processing trolley. The two fine-tuning structures are respectively installed with a turning tool and a grinding wheel, so that turning and grinding can be performed simultaneously.

[0052] See also Figures 1 to 3 As a specific embodiment of the boot surface processing trolley provided by the present application, the measuring pressure arm is provided with a slider slidingly arranged along the long axis direction, and the slider is driven by a screw along the long axis direction; the hinged end of the measuring pressure arm is provided with a pressure arm motor, and the pressure arm motor drives the screw. The linkage mechanism is hinged to the slider, so that the hinged position of the linkage mechanism and the measuring pressure arm can be changed by sliding the slider.

[0053] In this embodiment, after the diameter and axis position of the support roller are determined by the two guide wheels and the surface measurement unit on the measuring seat, the hinge position of the measuring pressure arm of the linkage mechanism can be changed according to the diameter of the support roller, and the relationship between the swing angle of the measuring pressure arm and the moving distance of the initial positioning platform can be changed, so as to better adapt to the switching of different support rollers. Figure 1 After the support roller in the apparatus is replaced with a support roller with a smaller diameter, the slider can be pushed by the screw to move closer to the support roller, so that the measuring pressure arm swings downward by the same angle, but can push the initial positioning platform to move a greater distance toward the support roller, so that the turning tool or grinding wheel is closer to the boot sleeve on the surface of the support roller. This is only an example, and those skilled in the art can determine the direction in which the slider is pushed by the screw according to actual conditions, so as to make the initial positioning platform closer to the support roller or further away from the support roller.

[0054] See also Figures 1 to 3 As a specific embodiment of the boot cover surface processing trolley provided by the present application, the linkage mechanism is a switchable linkage mechanism; the two ends of the switchable linkage mechanism are respectively connected to the measuring pressure arm and the fixed arm, and the switchable linkage mechanism can switch between a fixed distance at both ends and a freely changeable distance at both ends; when the switchable linkage mechanism is in a fixed distance state at both ends, the measuring pressure arm swings toward the support roller to drive the fixed arm and the movable arm to open, and the measuring pressure arm swings away from the support roller to drive the fixed arm and the movable arm to close. The boot cover surface processing trolley is also provided with a locking mechanism for fixing the position of the initial positioning table.

[0055] When in use, the switchable linkage mechanism is switched to a fixed distance at both ends, so that the swing of the measuring pressure arm can drive the fixed arm and the movable arm to open or close, completing the measurement preparation process. When the turning process is carried out, the switchable linkage mechanism is switched to a state where the distance between the two ends can be freely changed, so that the measuring pressure arm is decoupled from the fixed arm, so that the slight undulation of the surface of the boot sleeve drives the slight swing of the measuring pressure arm without driving the initial positioning table to move back and forth, avoiding affecting the turning accuracy.

[0056] After the turning process is carried out and the switchable linkage mechanism is switched to a state where the distance between the two ends can be freely changed, the initial positioning table is fixed by the locking mechanism so that the initial positioning table is fixed in the position during the turning process.

[0057] See also Figures 1 to 3 As a specific embodiment of the boot cover surface processing trolley provided in the present application, the switchable linkage mechanism includes an upper section rod, a middle section rod, a lower section rod and a switching drive; the front end of the upper section rod is hinged to the measuring pressure arm, and the rear end is hinged to the front end of the middle section rod, the front end of the lower section rod is hinged to the rear end of the middle section rod, and the rear end is hinged to the fixed arm; the rear end of the upper section rod and the front end of the lower section rod are respectively provided with a slot and a tenon; the switching drive drives the middle section rod to rotate relative to the upper section rod or the lower section rod so that the rear end of the upper section rod is merged or separated with the front end of the lower section rod, and when the rear end of the upper section rod is merged with the front end of the lower section rod, the slot and the tenon are engaged to realize the relative fixation of the upper section rod and the lower section rod in the directions at both ends.

[0058] In implementation, the upper section rod, the middle section rod, and the lower section rod are hinged end to end in sequence. The switching drive can be a motor and a reducer, and the switching drive is installed at the rear end of the upper section rod or the front end of the lower section rod, and drives the middle section rod to rotate, so that the rear end of the upper section rod and the front end of the lower section rod are merged or separated. When the rear end of the upper section rod is merged with the front end of the lower section rod, the slot and the tenon are engaged, so that the upper section rod and the lower section rod can withstand greater force in the axial direction and reduce the force on the rotating shaft. In implementation, the tenon can be designed to have a certain taper so that the slot and the tenon can be smoothly engaged.

[0059] See also Figures 1 to 3 As a specific embodiment of the boot cover surface processing trolley provided in the present application, the mounting frame includes a base plate and a column arranged on the base plate, the measuring pressure arm is hinged to the column, and the upper section rod and the lower section rod are combined and tilted toward the column.

[0060] The locking mechanism includes at least two top-butting grooves arranged on the column, and the lower section rod tilts toward each top-butting groove in a free state; the upper and lower positions of each top-butting groove are different, and they correspond to support rollers of different diameters. When the initial positioning platform slides to match a support roller of a certain diameter, the front end of the lower section rod is separated from the rear end of the upper section rod, and the lower section rod tilts freely so that the front end enters the corresponding top-butting groove.

[0061] In this embodiment, the base plate is a horizontal flat plate, which is lifted and lowered by the guide column and cylinder below, and the initial positioning platform slides horizontally forward and backward on the base plate. The column is vertically arranged at the rear of the base plate, and a plurality of top-butting grooves of different heights are arranged on the front side of the column. After the upper section rod and the lower section rod of the switchable linkage mechanism are combined, the overall column tilted toward the rear is tilted, so that after the upper section rod and the lower section rod are separated, the lower section rod freely tilts backward, so that the front end of the lower section rod enters the corresponding top-butting groove.

[0062] In specific implementation, the position and shape of each top-butting groove can be calculated or determined experimentally based on the diameters of various existing support rollers. For example, a prototype can be made first, and when processing each top-butting groove, the initial positioning table is first moved to match the turning tool with different types of support rollers according to the normal use state, and then the lower section rod is freely tilted backward, and the position and shape of the top-butting groove are determined by the position and angle of contact between the front end of the lower section rod and the column. Furthermore, a magnet can be set in the top-butting groove so that the front end of the lower section rod can be stably fixed after entering the top-butting groove.

[0063] See also Figures 1 to 3 As a specific implementation of the boot cover surface processing trolley provided in the present application, the measuring pressure arm is hinged to the column, and a cylinder is provided between the swing end of the measuring pressure arm and the top end of the column, and the cylinder drives the measuring pressure arm to swing.

[0064] In this embodiment, a cylinder is used to press the two guide wheels of the measuring seat onto the surface of the boot sleeve of the supporting roller with a certain pressure. The pressure of the cylinder should not be too large to avoid squeezing and deforming the boot sleeve.

[0065] See also Figures 1 to 3 As a specific embodiment of the boot surface processing trolley provided by the present application, the substrate is arranged horizontally, and a horizontal substrate guide rail is arranged on the top surface, the substrate guide rail is arranged along the radial direction of the support roller, and the initial positioning platform is slidably arranged on the substrate guide rail through a slider. The fine-tuning structure includes a precision guide rail, a precision screw and a mounting seat, and the mounting seat is slidably arranged on the precision guide rail through a slider; the precision screw rod is parallel to the precision guide rail and drives the mounting seat to slide.

[0066] In this embodiment, the initial positioning platform can also be provided with a certain damping structure, for example, a certain friction pad is provided between the substrate guide rail and the initial positioning platform, so that when the initial positioning platform is not pushed by external force (for example, when not driven by the linkage mechanism), it can be positioned more stably on the substrate guide rail.

[0067] See also Figures 1 to 3 As a specific embodiment of the boot cover surface processing trolley provided in the present application, within the cross section of the support roller, the projection position of the surface measurement unit is located at the midpoint of the line connecting the projection positions of the two guide wheels, and the measuring direction is perpendicular to the line connecting the two guide wheels.

[0068] This arrangement ensures that when the two guide wheels press against the surface of the boot sleeve on the periphery of the support roller, the surface measuring unit faces the axis of the support roller, and the distance on the boot sleeve surface detected by the surface measuring unit plus the support roller diameter and boot sleeve thickness is the distance between the surface measuring unit and the axis of the support roller.

[0069] In the implementation, in the initial state of the measuring seat, the relative positions of the two guide wheels and the elastic measurement are known. When the measuring pressure arm presses the two guide wheels against the surface of the boot sleeve on the periphery of the support roller, the distance of the boot sleeve surface detected by the surface measurement unit, combined with the relative positions of the two guide wheels and the surface measurement unit, the guide wheel diameter and the approximate thickness of the boot sleeve, can be calculated to determine the relative positions of the three points on the surface of the support roller, and then the approximate diameter of the support roller can be estimated. By comparing the calculated approximate diameter with several known support roller diameters in the database, the model of the support roller is determined, and then the use status information such as the axis height and axis horizontal position of the support roller in the use state is further obtained from the database, as well as the corresponding mounting frame lifting height, the position of the initial positioning table pushed by the folding arm mechanism, and the front and rear adjustment range of the turning tool by the fine-tuning structure, and then the control is performed. During the turning process, the thickness of the boot sleeve on the periphery of the support roller can be further accurately measured in real time by the surface measurement unit on the measuring seat, so that the front and rear position of the turning tool can be accurately controlled by the fine-tuning structure.

[0070] In a specific implementation, the surface measurement unit can adopt a laser detection device or a physical detection structure. As a specific implementation, the surface measurement unit can adopt an elastic measuring wheel for detection, which is located at the midpoint of the line connecting the two guide wheels and moves in a direction perpendicular to the line connecting the two guide wheels. When the two guide wheels collide with the boot sleeves on the periphery of the support roller, the elastic measuring wheel is squeezed by the boot sleeves on the periphery of the support roller to produce displacement, and the distance pushed is detected by the displacement detection sensor, so that the surface distance data of the boot sleeves on the periphery of the support roller can be obtained. Specifically, the elastic measuring wheel is installed on the measuring seat through a sliding structure, and the elastic measuring wheel is pushed toward the support roller by a spring. For example, a guide hole perpendicular to the line connecting the two guide wheels can be set on the measuring seat, a spring is installed in the guide hole, and then a sliding column at one end is inserted into the guide hole, and finally the elastic measuring wheel is installed at the end of the sliding column.

[0071] See also Figures 1 to 3 As a specific embodiment of the boot cover surface processing trolley provided in the present application, the boot cover surface processing trolley also includes a track parallel to the axial direction of the support roller, and the movable base moves along the track through rollers.

[0072] In this embodiment, the boot surface processing trolley runs along the track so that the distance between the boot surface processing trolley and the axis of the support roller remains stable.
