Description

Technical Field

[0001] The invention relates to the technical field of polishing devices, and more specifically to a device for polishing the surface of an acrylic plate. Background Art

[0002] Acrylic, also known as specially treated plexiglass, is a replacement product for plexiglass. Acrylic sheets made of acrylic materials have high hardness and weather resistance and are widely used in modern architecture, sanitary ware and handicrafts.

[0003] After the acrylic board is cut, the cut surface is relatively rough, with almost no transparency and is very smooth. At this time, the acrylic product needs to be polished and ground to achieve the gloss and transparency of the acrylic product. However, the existing acrylic board polishing device will deviate when fixed during the polishing process, resulting in that part of the acrylic board may not be polished during polishing. After one side is polished, the acrylic board needs to be moved and rotated manually, which can easily lead to excessive movement, resulting in higher safety accidents, increasing the degree of product accidents, and reducing the polishing efficiency of the device.

[0004] In view of the above problems, some solutions are also provided in the prior art. For example, the Chinese utility model patent with announcement number CN219403806U discloses a polishing device based on acrylic plate, in which the bidirectional screw is rotated by turning the hand on the polishing table to move the threaded block and the fixing frame, so that the suction cup in front of the fixing frame fixes the acrylic plate to avoid movement during the polishing process of the acrylic plate, thereby affecting the polishing efficiency. Although the prior art can improve the polishing efficiency to a certain extent, in actual operation, the existing user rotates the bidirectional screw to fix the acrylic plate, and after the polishing is completed, the existing user rotates the reverse screw again to release the fixation of the acrylic plate, thereby seriously affecting the polishing efficiency of the acrylic plate. Summary of the invention

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide an acrylic plate surface polishing device, which can achieve the purpose of improving the polishing efficiency of the acrylic plate.

[0009] Furthermore, the locking assembly includes a slide groove opened on the mounting plate, a limit rod is installed in the slide groove for sliding sealing, limit grooves are evenly opened on the side wall of the sleeve, a return spring is installed between the limit rod and the slide groove, a cavity is opened on the elastic pad, and a connecting pipe connected to the slide groove is inserted into the cavity.

[0010] Furthermore, the burr processing component includes a vertical groove opened on the clamping block, a slider is slidably installed in the vertical groove, a cutting plate is fixedly installed on the slider, a second spring is commonly installed between the slider and the vertical groove, a telescopic tube is commonly installed between the mounting frame and the horizontal plate, a first air pipe connected to the telescopic tube is inserted on the mounting frame, a connecting component is provided on the mounting frame, and the first air pipe is connected through the vertical groove of the connecting component.

[0011] Furthermore, the connecting component includes a mounting groove provided on the mounting frame, a connecting rod is slidably installed in the mounting groove, a third spring is commonly installed between the top wall of the connecting rod and the mounting groove, a connecting hole is provided on the connecting rod, and a second air pipe connected to the connecting hole is inserted into the vertical groove, an exhaust valve is inserted into the mounting groove, and a third air pipe connected to the first air pipe is inserted into the output end of the exhaust valve.

[0012] Furthermore, a waste box is installed on the workbench, an air pump is fixedly installed on the waste box, a filter screen that cooperates with the input end of the air pump is embedded on the waste box, a cleaning rod is installed on the polishing frame, a cleaning cavity is opened on the cleaning rod, cleaning holes are evenly opened on the cleaning cavity, and a waste pipe connected with the waste box is installed on the cleaning cavity.

[0013] Furthermore, a pneumatic telescopic rod is fixedly installed on the waste box, a scraper matching the filter is fixedly installed on the output end of the pneumatic telescopic rod, and a fourth air pipe connected to the sleeve is inserted on the input end of the pneumatic telescopic rod.

[0014] Furthermore, the top wall of the cutting plate is an inclined surface.

[0015] Furthermore, the surface of the limiting rod is a smooth mirror surface.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) This solution uses the cooperation between the coil and the magnet block. After the coil is energized, the electromagnetic field fixes the acrylic plate through the magnet block, the linkage block, the mounting plate, the fixing rod, and the clamping block. After the electric telescopic rod is used up and the power is turned off, the coil is powered off and the electromagnetic field disappears. Then the first spring stretches and drives the clamping block to reset through the mounting plate and the fixing rod, thereby releasing the fixation of the acrylic plate. Therefore, the user does not need to spend time manually fixing the acrylic plate, nor does the user need to spend time manually releasing the fixation of the acrylic plate, thereby improving the polishing efficiency.

[0018] (2) In this scheme, by setting a limit rod, the gas in the cavity is squeezed during the process of the linkage block compressing the elastic pad. Then, after the side wall of the clamping block is attached to the side wall of the acrylic plate, the limit rod contacts the limit groove. At this time, the airflow in the cavity flows into the slide groove through the first air pipe, and the limit rod moves along the slide groove and is inserted into the limit groove. Then, under the action of the limit rod and the limit groove, the mounting plate is fixed, that is, the clamping block is fixed at this time, further preventing the acrylic plate from moving during the polishing process of the acrylic plate, thereby improving the fixing effect of the acrylic plate;

[0019] (3) This solution sets a cutting plate. When the output end of the electric telescopic rod extends and drives the horizontal plate to move upward, the telescopic tube contracts. At this time, the airflow in the telescopic tube flows into the vertical groove through the first air pipe and the connecting component. Then the second spring extends and drives the slider to move upward along the vertical groove. In the process of the slider moving upward, the cutting plate is driven to move upward and the burrs on the left and right sides of the acrylic plate are cut. Therefore, the user does not need to spend time to process the burrs on the left and right sides of the acrylic plate again, which improves the polishing efficiency of the acrylic plate.

[0020] (4) By setting up a connecting component, this solution can ensure that the cutting plate can process the burrs of the acrylic plate only after the polishing roller and the acrylic plate are separated, thereby avoiding contact between the cutting plate and the polishing roller, which will accelerate the wear of the polishing roller and the cutting plate, and require users to frequently replace the polishing roller and the cutting plate, further improving the polishing efficiency;

[0021] (5) This solution sets a filter box. When the polishing roller is polishing the acrylic plate, the user can start the air pump. At this time, the air pump sucks air through the filter screen, waste box, waste pipe, cleaning chamber, and cleaning hole. Then, the debris in the polishing process enters the waste box along with the air flow, so that the user does not need to waste time on the debris, which further improves the polishing efficiency.

[0022] (6) In this scheme, a pneumatic telescopic rod is provided. When the mounting plate moves along the sleeve and compresses the first spring, the airflow in the sleeve is squeezed and flows into the pneumatic telescopic rod through the fourth air pipe. Then, under the action of the airflow, the output end of the pneumatic telescopic rod extends and drives the scraper to clean the debris adhering to the bottom wall of the filter. When the first spring extends and drives the mounting plate to reset, the sleeve inhales air from the input end of the pneumatic telescopic rod through the fourth air pipe. Then, the output end of the pneumatic telescopic rod contracts and drives the scraper to reset. This eliminates the need for users to frequently spend time cleaning the filter, thereby further improving the polishing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 8 , an acrylic plate surface polishing device, comprising a workbench 1, a mounting frame 2 is fixedly mounted on the top wall of the workbench 1, an electric telescopic rod 3 is fixedly mounted on the mounting frame 2, a horizontal plate 4 is fixedly mounted on the bottom wall of the electric telescopic rod 3, an electric slide rail 5 is provided on the horizontal plate 4, a polishing frame 7 is slidably mounted on the electric slide rail 5, a polishing roller 6 is rotatably mounted on the polishing frame 7, a motor 8 whose output end is fixedly connected to the polishing roller 6 is fixedly mounted on the horizontal plate 4, and a clamping assembly 9 cooperating with the polishing roller 6 is provided on the workbench 1;

[0040] The clamping assembly 9 includes a sleeve 901 symmetrically mounted on the mounting frame 2, a mounting plate 902 is slidingly and sealably mounted inside the sleeve 901, a first spring 903 is commonly mounted between the mounting plate 902 and the sleeve 901, a fixing rod 904 is fixedly mounted on the mounting plate 902, a clamping block 905 is fixedly mounted on one end of the fixing rod 904 away from the mounting plate 902, a burr processing assembly 11 is provided on the clamping block 905, an elastic pad 906 is fixedly mounted on the side wall of the mounting plate 902, a linkage block 907 is mounted on one end of the elastic pad 906 away from the mounting plate 902, a magnet block 908 is embedded on the linkage block 907, a coil 909 cooperating with the magnet block 908 is embedded on the mounting frame 2, and the coil 909 is electrically connected to the electric telescopic rod 3, and a locking assembly 10 is provided on the mounting plate 902.

[0041] The locking assembly 10 includes a slide groove opened on the mounting plate 902, a limit rod 101 is installed in the slide groove with a sliding seal, the limit grooves 102 are evenly opened on the side wall of the sleeve 901, a return spring 103 is installed between the limit rod 101 and the slide groove, a cavity 104 is opened on the elastic pad 906, and a connecting pipe 105 connected to the slide groove is inserted in the cavity 104.

[0042] When in use, the acrylic plate is placed on the top wall of the workbench 1, and then the user can start the electric telescopic rod 3, and then the output end of the electric telescopic rod 3 extends and drives the horizontal plate 4 to move downward. During the downward movement of the horizontal plate 4, the polishing roller 6 is driven downward by the electric slide rail 5 and the polishing frame 7, and gradually contacts the acrylic plate. At the same time, the motor 8 drives the polishing roller 6 to rotate and polish the acrylic plate, and during the rotation of the polishing roller 6, the electric slide rail 5 drives the polishing roller 6 to move through the polishing frame 7, thereby achieving the purpose of polishing the acrylic plate. At the same time, during the power-on operation of the electric telescopic rod 3, the coil 909 is energized and generates an electromagnetic field, and then under the action of the electromagnetic field, the magnet block 908 drives the linkage block 907 to move in the direction of the elastic pad 906. At this time, the elastic pad 906 is compressed, and after the elastic pad 906 reaches the maximum compression degree, the linkage block 907 drives the mounting plate 902 to move and compress the first spring 903 through the elastic pad 906, and during the movement of the mounting plate 902, the first spring 903 is compressed by the fixed The rod 904 drives the clamping block 905 to gradually contact the acrylic plate and clamp the acrylic plate, thereby preventing the acrylic plate from moving during the polishing process of the acrylic plate. After the polishing is completed, the output end of the electric telescopic rod 3 shrinks, and then during the shrinkage of the output end of the electric telescopic rod 3, the polishing roller 6 is driven to reset through the horizontal plate 4, the electric slide rail 5, and the polishing frame 7. After the reset of the polishing roller 6 is completed, the electric telescopic rod 3 is powered off and closed. At this time, the coil 909 is powered off, and then the electromagnetic field of the coil 909 disappears. At this time, the elastic pad 906 stretches and drives the linkage block 907 to reset. At the same time, the first spring 903 stretches and drives the mounting plate 902 to reset. During the reset of the mounting plate 902, the clamping block 905 is driven to reset and release the fixation of the acrylic plate through the fixing rod 904. Then, the user can remove the acrylic plate after polishing, so that the user does not need to spend time manually fixing the acrylic plate, and does not need to spend time manually releasing the fixation of the acrylic plate, thereby improving the polishing efficiency.

[0043] In the process of the linkage block 907 compressing the elastic pad 906, the gas in the cavity 104 is squeezed and tends to flow to the outside, and then the limiting rod 101 is driven to move in the process of the movement of the mounting plate 902, and after the side wall of the clamping block 905 is in contact with the side wall of the acrylic plate, the limiting rod 101 contacts the limiting groove 102, and the airflow in the cavity 104 flows into the slide groove through the first air pipe 114, and the pressure in the slide groove is increased, and then the limiting rod 101 moves along the slide groove and is inserted into the limiting groove 102 under the action of the pressure, and the return spring 103 is stretched and has a tendency to recover, and then the mounting plate 902 is fixed under the action of the limiting rod 101 and the limiting groove 102, that is, the clamping block 905 is fixed at this time, further avoiding the movement of the acrylic plate during the polishing of the acrylic plate, thereby further improving the fixing effect of the acrylic plate.

[0044] Then, after the coil 909 is powered off, the elastic pad 906 stretches and drives the linkage block 907 to reset. During the stretching process of the elastic pad 906, the cavity 104 draws air from the slide groove through the first air pipe 114. At this time, the reset spring 103 gradually contracts and drives the limit rod 101 to reset. During the reset process of the limit rod 101, it gradually loses contact with the limit groove 102, thereby releasing the fixation of the mounting plate 902, and then facilitating the stretching of the first spring 903 and driving the clamping block 905 to reset through the mounting plate 902 and the fixing rod 904, and automatically releasing the fixation of the acrylic plate, thereby facilitating the release of the fixation of the acrylic plate.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the burr processing component 11 includes a vertical groove opened on the clamping block 905, a slider 110 is slidably installed in the vertical groove, a cutting plate 111 is fixedly installed on the slider 110, a second spring 112 is installed between the slider 110 and the vertical groove, a telescopic tube 113 is installed between the mounting frame 2 and the horizontal plate 4, a first air pipe 114 connected to the telescopic tube 113 is inserted on the mounting frame 2, a connecting component 115 is provided on the mounting frame 2, and the first air pipe 114 is connected to the vertical groove through the connecting component 115.

[0046] The connecting component 115 includes a mounting groove provided on the mounting frame 2, a connecting rod 1151 is slidably installed in the mounting groove, a third spring 1152 is installed between the top wall of the connecting rod 1151 and the mounting groove, a connecting hole 1153 is provided on the connecting rod 1151, and a second air pipe 1154 connected to the connecting hole 1153 is inserted in the vertical groove, an exhaust valve 1155 is inserted in the mounting groove, and a third air pipe 1156 connected to the first air pipe 114 is inserted at the output end of the exhaust valve 1155.

[0047] By adopting the above technical solution, in the process of the clamping block 905 clamping the acrylic plate, the side wall of the cutting plate 111 gradually fits with the side wall of the acrylic plate, and in the process of the output end of the electric telescopic rod 3 extending and driving the horizontal plate 4 to move downward, the telescopic tube 113 is stretched, and then under the action of the telescopic tube 113, it can prevent the debris of the acrylic plate from adhering to the output end of the electric telescopic rod 3 and affecting the service life of the electric telescopic rod 3. At the same time, in the process of the telescopic tube 113 being stretched, the telescopic tube 113 inhales air from the vertical groove through the second air pipe 1154, the third air pipe 1156, and the exhaust valve 1155, and reduces the gas pressure in the vertical groove, and then under the action of the pressure, the slider 110 drives the cutting plate 111 to move downward, at this time, the second spring 112 is compressed and has a tendency to recover, and then During the polishing process of the plate, burrs will appear on the edge of the acrylic plate. Then, when the polishing roller 6 moves to the front and rear sides of the acrylic plate, the operator can use the electric telescopic rod 3 to move the polishing roller 6 downward and grind the burrs on the front and rear sides of the acrylic plate. Then, the output end of the electric telescopic rod 3 extends and drives the horizontal plate 4 to move upward, and the telescopic tube 113 contracts. At this time, the airflow in the telescopic tube 113 flows into the vertical groove through the first air pipe 114 and the connecting component 115. Then, the second spring 112 extends and drives the slider 110 to move upward along the vertical groove. In the process of the slider 110 moving upward, it drives the cutting plate 111 to move upward and cuts the burrs on the left and right sides of the acrylic plate, so that the user does not need to spend time processing the burrs on the left and right sides of the acrylic plate again, which improves the polishing efficiency of the acrylic plate.

[0048] During the upward movement of the horizontal plate 4, it gradually disengages from the connecting rod 1151. At this time, the third spring 1152 stretches and drives the connecting rod 1151 to move downward, and during the downward movement of the connecting rod 1151, it drives the connecting hole 1153 to disengage from the first air pipe 114. Then, during the upward movement of the horizontal plate 4 and the contraction of the telescopic tube 113, the air flow in the telescopic tube 113 tends to flow to the outside. Then, during the upward movement of the horizontal plate 4, it gradually contacts the connecting rod 1151 and drives the connecting rod 1151 to move upward. After the polishing roller 6 is away from the acrylic plate, the connecting rod 1151 drives the connecting hole 1153 to disengage from the first air pipe 114. The tube 114 is connected, and the air flow in the telescopic tube 113 flows into the vertical groove through the first air pipe 114, the connecting hole 1153, and the second air pipe 1154. At this time, the second spring 112 stretches and drives the cutting plate 111 to cut the burrs on the left and right sides of the plate through the slider 110. That is, by setting the connecting component 115, it can be ensured that the cutting plate 111 can process the burrs of the acrylic plate only after the polishing roller 6 is away from the acrylic plate, thereby avoiding the contact between the cutting plate 111 and the polishing roller 6, and causing the wear of the polishing roller 6 and the cutting plate 111 to be accelerated, so that the user needs to frequently replace the polishing roller 6 and the cutting plate 111, thereby further improving the polishing efficiency.

[0049] like Figure 1 , Figure 5 , Figure 6 As shown, a waste box 121 is installed on the workbench 1, an air pump 122 is fixedly installed on the waste box 121, a filter screen 123 that cooperates with the input end of the air pump 122 is embedded in the waste box 121, a cleaning rod 124 is installed on the polishing frame 7, a cleaning cavity 125 is opened on the cleaning rod 124, cleaning holes 126 are evenly opened on the cleaning cavity 125, and a waste pipe 127 connected with the waste box 121 is installed on the cleaning cavity 125.

[0050] A pneumatic telescopic rod 131 is fixedly installed on the waste box 121 , a scraper 132 cooperating with the filter 123 is fixedly installed on the output end of the pneumatic telescopic rod 131 , and a fourth air pipe 133 connected to the sleeve 901 is inserted on the input end of the pneumatic telescopic rod 131 .

[0051] By adopting the above technical solution, since the debris during the polishing process will affect the user's observation of the polishing effect, the user needs to spend time cleaning the debris, which seriously affects the polishing efficiency. Then, while the polishing roller 6 is polishing the acrylic plate, the user can start the air pump 122. At this time, the air pump 122 inhales air through the filter 123, the waste box 121, the waste pipe 127, the cleaning chamber 125, and the cleaning hole 126. Then, the debris in the polishing process enters the waste box 121 together with the air flow, so the user does not need to waste time on the debris, thereby further improving the polishing efficiency.

[0052] After the debris enters the waste box 121, some of the debris will adhere to the surface of the filter 123. If the debris accumulates for a long time, it will easily affect the debris processing effect. Therefore, the user needs to frequently clean the filter 123. Then, in the process of the mounting plate 902 moving along the sleeve 901 and compressing the first spring 903, the airflow in the sleeve 901 is squeezed and flows into the pneumatic telescopic rod 131 through the fourth air pipe 133. Then, under the action of the airflow, the output end of the pneumatic telescopic rod 131 extends and drives the scraper 132 to clean the debris adhered to the bottom wall of the filter 123. In the process of the first spring 903 extending and driving the mounting plate 902 to reset, the sleeve 901 inhales air from the input end of the pneumatic telescopic rod 131 through the fourth air pipe 133, and then the output end of the pneumatic telescopic rod 131 contracts and drives the scraper 132 to reset, so that the user does not need to spend time frequently cleaning the filter 123, thereby further improving the polishing efficiency.

[0053] like Figure 2 As shown, the top wall of the cutting plate 111 is an inclined surface.

[0054] By adopting the above technical solution, during the process of the cutting board 111 processing the burrs of the acrylic board, by making the top wall of the cutting board 111 an inclined surface, the contact area between the cutting board 111 and the acrylic board can be reduced, thereby increasing the cutting force of the cutting board 111 on the burrs of the acrylic board, thereby improving the effect of processing the burrs of the acrylic board.

[0055] like Figure 8 As shown, the surface of the limiting rod 101 is a smooth mirror surface.

[0056] By adopting the above technical solution, during the process of inserting the limiting rod 101 into the limiting groove 102 , by making the surface of the limiting rod 101 a smooth mirror surface, the friction between the limiting rod 101 and the limiting groove 102 can be reduced, thereby facilitating the insertion of the limiting rod 101 into the limiting groove 102 .

[0057] Instructions for use: When in use, place the acrylic plate on the top wall of the workbench 1, and then the user can start the electric telescopic rod 3, and then the output end of the electric telescopic rod 3 extends and drives the horizontal plate 4 to move downward. During the downward movement of the horizontal plate 4, the polishing roller 6 is driven downward by the electric slide rail 5 and the polishing frame 7, and gradually contacts with the acrylic plate. At the same time, the motor 8 drives the polishing roller 6 to rotate and polish the acrylic plate. During the rotation of the polishing roller 6, the electric slide rail 5 drives the polishing roller 6 to move through the polishing frame 7, thereby achieving the purpose of polishing the acrylic plate. At the same time, during the power-on operation of the electric telescopic rod 3, the coil 909 is energized and generates an electromagnetic field, and then Under the action of the electromagnetic field, the magnet block 908 drives the linkage block 907 to move in the direction of the elastic pad 906. At this time, the elastic pad 906 is compressed. After the elastic pad 906 reaches the maximum compression degree, the linkage block 907 drives the mounting plate 902 to move and compress the first spring 903 through the elastic pad 906. In the process of the movement of the mounting plate 902, the clamping block 905 is driven to gradually contact the acrylic plate through the fixing rod 904, and the acrylic plate is clamped, thereby preventing the acrylic plate from moving during the polishing of the acrylic plate. After the polishing is completed, the output end of the electric telescopic rod 3 is contracted, and then in the process of the contraction of the output end of the electric telescopic rod 3, the horizontal plate 4, the electric slide rail 5, and the polishing The optical frame 7 drives the polishing roller 6 to reset, and after the polishing roller 6 is reset, the electric telescopic rod 3 is powered off and closed, at which time the coil 909 is powered off, and then the electromagnetic field of the coil 909 disappears, at which time the elastic pad 906 stretches and drives the linkage block 907 to reset, and at the same time the first spring 903 stretches and drives the mounting plate 902 to reset, and during the resetting process of the mounting plate 902, the clamping block 905 is driven to reset and release the fixation of the acrylic plate through the fixing rod 904, and then the user can remove the acrylic plate after polishing, so that the user does not need to spend time manually fixing the acrylic plate; during the process of the linkage block 907 compressing the elastic pad 906, the gas in the cavity 104 is squeezed and flows to The outer trend, and then in the process of the movement of the mounting plate 902, the limiting rod 101 is driven to move, and after the side wall of the clamping block 905 is attached to the side wall of the acrylic plate, the limiting rod 101 contacts the limiting groove 102, and at this time, the airflow in the cavity 104 flows into the slide groove through the first air pipe 114, and the pressure in the slide groove is increased, and then under the action of the pressure, the limiting rod 101 moves along the slide groove and is inserted into the limiting groove 102, and at this time, the return spring 103 is stretched and has a tendency to recover, and then under the action of the limiting rod 101 and the limiting groove 102, the mounting plate 902 is fixed, that is, the clamping block 905 is fixed at this time, further preventing the acrylic plate from moving during the polishing process of the acrylic plate;When the output end of the electric telescopic rod 3 extends and drives the horizontal plate 4 to move upward, the telescopic tube 113 contracts. At this time, the airflow in the telescopic tube 113 flows into the vertical groove through the first air pipe 114 and the connecting component 115. Then the second spring 112 extends and drives the slider 110 to move upward along the vertical groove. In the process of the slider 110 moving upward, the cutting plate 111 is driven to move upward and cut the burrs on the left and right sides of the acrylic plate, so that the user does not need to spend time processing the burrs on the left and right sides of the acrylic plate again; in the process of polishing the acrylic plate with the polishing roller 6, the user The air pump 122 can be started, and the air pump 122 inhales air through the filter 123, the waste box 121, the waste pipe 127, the cleaning chamber 125, and the cleaning hole 126, and then the debris in the polishing process enters the waste box 121 together with the air flow; when the mounting plate 902 moves along the sleeve 901 and compresses the first spring 903, the air flow in the sleeve 901 is squeezed and flows into the pneumatic telescopic rod 131 through the fourth air pipe 133, and then the output end of the pneumatic telescopic rod 131 extends under the action of the air flow and drives the scraper 132 to clean the debris adhering to the bottom wall of the filter 123. ;
