Description

Technical Field

[0001] The present application relates to the technical field of saw band processing, and in particular to a cleaning device and method for saw band processing. Background Art

[0002] A saw belt is a long saw blade, usually made of high-strength metal material with sharp teeth. It is not only suitable for cutting various materials, but also suitable for various industrial and manufacturing occasions to meet different cutting and forming needs.

[0003] During the processing of the saw band, a large amount of chips or oil will often remain on the surface of the saw band. The presence of these deposits may cause the saw band to wear more severely during subsequent use. Therefore, before the saw band is put into use, it is necessary to use a cleaning equipment to clean the saw band in order to remove the deposits remaining on the surface of the saw band.

[0004] Referring to the Chinese patent document with the announcement number CN218554928U and the announcement date of March 3, 2023, the name is a band saw cleaning device. The cleaning work of the saw band is completed by alternating the use of high-pressure water washing and brush scrubbing. Compared with the method of always using brush scrubbing, the contact time between the brush and the saw band during the entire cleaning process can be reduced, thereby reducing the wear between the brush and the saw band and extending the service life of the brush and the saw band.

[0005] Referring to the above technical solution, when the saw belt is cleaned by scrubbing with a brush, due to the presence of saw teeth on the saw belt, when the high-speed moving saw belt comes into contact with the stationary brush, the sharp edges of the saw teeth are likely to cause greater wear on the brush, which may cause the bristles on the brush to fall off or break, thereby affecting the subsequent cleaning effect of the saw belt. Summary of the invention

[0006] In view of this, the present application provides a cleaning device and method for saw belt processing, which are mainly used to solve the problem that the brush is easily damaged when contacting with the saw teeth on the saw belt, thereby affecting the cleaning effect.

[0007] In order to solve the above technical problems, the present application provides a cleaning device and method for saw belt processing.

[0008] In the first aspect, the present application provides a cleaning device for saw band processing, including a cleaning box and a cleaning chamber and a storage chamber opened therein, a carrying plate and a feeding plate are arranged inside the cleaning chamber, and the right end of the feeding plate extends to the top of the storage chamber; a brush roller is arranged at the bottom of the carrying plate, and a small-diameter gear is arranged on the central axis of the brush roller, a tensioning slider is vertically slidably connected to the carrying plate, a cylinder is arranged at the front end of the tensioning slider, a transition frame is arranged at the actuator end of the cylinder, and a tensioning wheel is arranged at the rear end of the transition frame, and a gear that can A large diameter gear that can mesh with a small diameter gear; a first driving member is arranged on the bearing plate, which is used to drive the tensioning slider to perform vertical displacement; a linear driver is arranged on the loading plate, and a loading roller is arranged at the execution end of the linear driver, and a unwinding roller, a winding roller and two driving motors for driving the unwinding roller or the winding roller to rotate independently are arranged at the right end of the loading plate, and two clamping rollers located between the unwinding roller and the winding roller are vertically slidably connected to the right end of the loading plate, and a second driving member for making the two clamping rollers move closer to each other or away from each other is arranged at the right end of the loading plate.

[0009] By adopting the above technical solution, a brush roller is used instead of a brush to clean the saw band, and the bristles on the brush roller can alternately contact the saw band, thereby reducing the friction damage between the bristles and the saw band, so that the cleaning work of the saw band can be carried out continuously.

[0015] Optionally, the second driving member includes a bidirectional screw rod rotatably connected to the right end of the loading plate, the two ends of the bidirectional screw rod are respectively threadedly connected to the two clamping rollers, and the right end of the loading plate is provided with a second motor for driving the bidirectional screw rod to rotate.

[0016] By adopting the above technical solution, when the second motor drives the bidirectional screw to rotate, the two clamping rollers can be moved away from each other, so that the two clamping rollers cooperate with the unwinding roller or the winding roller to clamp the saw belt, so that the saw belt can hold force normally during subsequent transportation.

[0017] Optionally, two groups of upper and lower symmetrical limit assemblies are provided at the right end of the loading plate, each limit assembly includes two transmission wheels rotatably connected to the right end of the loading plate, and a limit belt is provided between the two transmission wheels in a belt drive manner. The limit belt is horizontally arranged and corresponds to the position of the saw belt.

[0020] By adopting the above technical solution, the saw belt can be prevented from deviating forward by blocking the limit step.

[0021] In a second aspect, the present application provides a saw band processing cleaning method, which is applied to a saw band processing cleaning device as described in the first aspect, and the cleaning method comprises:

[0022] S1, firstly, the saw belt is sleeved on the outside of the whole composed of the feeding roller and the two pressing rollers, and the saw belt should be located in the gap between the unwinding roller and the winding roller, and then the saw belt is placed in the storage bin with the help of external auxiliary tooling;

[0023] S2, the feeding roller is laterally displaced to the left side of the tensioning wheel through the cooperation of the linear drive, and then the tensioning wheel is coupled with the saw belt under the cooperation of the cylinder, and then the tensioning wheel is moved down through the cooperation of the first driving member until the large-diameter gear and the small-diameter gear are engaged, at which time part of the saw belt body is immersed in the cleaning liquid stored in advance in the cleaning chamber, and at the same time, the part of the saw belt body pulled by the tensioning wheel will abut against the brush roller;

[0024] S3, the second driving member is operated to make the two clamping rollers move away from each other, at which time the two clamping rollers will respectively abut against the upper and lower layers of the saw belt and press them to the outer surfaces of the unwinding roller and the winding roller, so that the saw belt can hold force normally during the subsequent transmission process, and then the two driving motors are operated to drive the unwinding roller and the winding roller to rotate synchronously, so that the position of the saw belt changes in a belt transmission manner, so that the brush roller scrubs the surface of the saw belt.

[0025] By adopting the above technical solution, the saw belt loading and cleaning work can be automatically completed, reducing the loading operation steps for personnel, thereby reducing the possibility of harm to personnel when loading the saw belt.

[0026] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0027] 1. Use a rotatable brush roller instead of a brush to clean the saw band. Compared with a fixed brush, the bristles on the brush roller will alternately contact the saw band, which can reduce the friction damage between the bristles and the saw band to a certain extent. When the brush roller rotates, it can throw out impurities on its surface under the action of centrifugal force, which is beneficial to the improvement of subsequent cleaning quality. At the same time, the brush roller is rotated at a speed higher than the conveying speed of the saw band by differential transmission. At the same time, the wiping force applied by the brush roller on the saw band is in the same direction as the inclination direction of the saw teeth on the saw band, reducing the instantaneous pressure of the bristles when they contact the saw band, thereby reducing the probability of the bristles being damaged by the saw teeth.

[0028] 2. Before cleaning the saw band, an appropriate number of cleaning components can be connected to the tensioning work according to the actual length of the saw band, so that the longer saw band can be fully tensioned. This can not only meet the cleaning needs of saw bands of different lengths, but also with the cooperation of multiple cleaning components, it can improve the cleaning effect of the saw band in a multi-stage cleaning manner.

[0029] 3. During the conveying process of the saw belt, targeted limiting can be performed according to the end face shape of the saw belt to reduce the possibility of the saw belt running forward and backward, so that the cleaning work of the saw belt can be carried out stably.

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 6 , the technical solutions of the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0038] In a first aspect, the present application provides a cleaning device for saw belt processing, which adopts the following technical solution:

[0039] Reference Figure 1 and Figure 2 The present embodiment provides a cleaning device for saw band processing, comprising a cleaning box 1, a cleaning assembly and a feeding assembly. A cleaning chamber 11 and a storage chamber 12 are provided inside the cleaning box 1, a carrying plate 2 and a feeding plate 3 are provided inside the cleaning chamber 11, and the right end of the feeding plate 3 extends above the storage chamber 12. The cleaning assembly is arranged on the carrying plate 2 for cleaning the saw band. The feeding assembly is arranged on the feeding plate 3 for transferring the saw band to the cleaning station.

[0040] Among them, refer to Figure 2 , Figure 3 and Figure 4The cleaning assembly includes a brush roller 4, a tensioning slider 5, a coupling unit, a tensioning wheel 53, a transmission unit and a first driving member 6. The brush roller 4 is rotatably connected to the bottom of the bearing plate 2, the tensioning slider 5 is vertically slidably connected to the bearing plate 2, and the tensioning wheel 53 is arranged on the tensioning slider 5; the coupling unit is arranged between the tensioning wheel 53 and the tensioning slider 5, and is used to connect the tensioning wheel 53 to the tensioning work of the saw belt; the transmission unit is arranged between the brush roller 4 and the tensioning wheel 53, and is used to make the brush roller 4 rotate along with the tensioning wheel 53; the first driving member 6 includes a one-way screw 61 and a first motor 62, the one-way screw 61 is rotatably connected to the bearing plate 2, and the one-way screw 61 is threadedly connected to the tensioning slider 5, the first motor 62 is arranged on the bearing plate 2, and the first motor 62 can drive the one-way screw 61 to rotate when it is running, so that the tensioning slider 5 is vertically displaced.

[0041] Among them, refer to Figure 2 , Figure 3 and Figure 4 The coupling unit includes a cylinder 51 and a transition frame 52. The cylinder 51 is arranged at the front end of the tensioning slider 5, and the transition frame 52 is arranged at the execution end of the cylinder 51. The transition frame 52 is longitudinally slidably connected to the tensioning slider 5, and the tensioning wheel 53 is rotatably connected to the rear end of the transition frame 52. When the cylinder 51 extends backward, the transition frame 52 and the tensioning wheel 53 will move backward together, so that the tensioning wheel 53 is connected to the tensioning work of the saw belt.

[0042] Among them, refer to Figure 4 The transmission unit includes a small diameter gear 41 and a large diameter gear 54. The small diameter gear 41 is arranged on the central axis of the brush roller 4, and the large diameter gear 54 is arranged on the central axis of the tension wheel 53 and can mesh with the small diameter gear 41. When the tension wheel 53 where the large diameter gear 54 is located rotates due to the saw belt transmission, the brush roller 4 where the small diameter gear 41 is located can rotate at a faster speed due to the difference in the number of teeth between the small diameter gear 41 and the large diameter gear 54.

[0043] Among them, refer to Figure 2 , Figure 3 and Figure 5The feeding assembly includes a linear drive 31 , a feeding roller 32 , a unwinding roller 33 , a winding roller 34 , two driving motors 35 , two pressing rollers 36 and a second driving member 37 . The linear drive 31 is arranged on the loading plate 3. The linear drive 31 can be in the form of a combination of a screw and a servo motor that can drive the screw to rotate. The loading roller 32 is rotatably connected to the execution end of the linear drive 31; the unwinding roller 33 and the winding roller 34 are both rotatably connected to the right end of the loading plate 3, and the two driving motors 35 are both arranged at the right end of the loading plate 3 and can drive the unwinding roller 33 and the winding roller 34 to rotate independently; the two clamping rollers 36 are both vertically slidably connected to the right end of the loading plate 3, and the two clamping rollers 36 are both located between the unwinding roller 33 and the winding roller 34; the second driving member 37 includes a bidirectional screw 371 and a second motor 372, the bidirectional screw 371 is rotatably connected to the right end of the loading plate 3, and the two ends of the bidirectional screw 371 are respectively threadedly connected to the two clamping rollers 36, and the second motor 372 is arranged at the right end of the loading plate 3. When the second motor 372 is running, it can drive the bidirectional screw 371 to rotate, so that the two clamping rollers 36 move closer to each other or move away from each other.

[0044] When cleaning the saw band, since the saw band is usually in the shape of an endless band, personnel can first put the saw band on the outside of the whole formed by the feeding roller 32 and the two clamping rollers 36, so that the saw band is located in the gap between the unwinding roller 33 and the winding roller 34, and then use external auxiliary tooling to place the saw band inside the storage bin 12 to complete the initial feeding of the saw band.

[0045] Then, the linear drive 31 runs to drive the feeding roller 32 to move laterally until the feeding roller 32 moves to the left side of the tensioning wheel 53. At this time, the cylinder 51 drives the transition frame 52 and the tensioning wheel 53 to move backward, so that the tensioning wheel 53 is connected to the tensioning work of the saw belt, and then the tensioning wheel 53 is moved down through the cooperation of the first driving member 6 to put the saw belt in a tensioned state. At this time, part of the saw belt body is immersed in the cleaning liquid stored in the cleaning chamber 11 in advance, and the large diameter gear 54 will mesh with the small diameter gear 41, and at the same time, the part of the saw belt body pulled by the tensioning wheel 53 will abut against the brush roller 4.

[0046] Finally, the second driving member 37 operates to make the two clamping rollers 36 face away from each other, so that the two clamping rollers 36 respectively abut the upper and lower layers of the saw band and clamp them to the outer surfaces of the unwinding roller 33 and the winding roller 34. In this state, when the two driving motors 35 operate to drive the unwinding roller 33 and the winding roller 34 to rotate synchronously, the position of the saw band can be changed in a belt transmission manner, so that the brush roller 4 scrubs the surface of the saw band, and the conveying direction of the saw band should be the same as the inclination direction of the saw teeth on the saw band; when the speed difference generated by the small-diameter gear 41 and the large-diameter gear 54 is used to drive the brush roller 4 to rotate at a speed higher than the conveying speed of the saw band, the rotation direction of the brush roller 4 is opposite to the rotation direction of the tensioning wheel 53, so that the wiping force applied by the brush roller 4 to the saw band can be the same as the inclination direction of the saw teeth on the saw band. In this state, when the bristles on the brush roller 4 contact the saw teeth, relative motion is formed between the two. When the bristles on the brush roller 4 contact the saw band, they can wipe off impurities on the saw band with less pressure, thereby reducing wear caused by friction.

[0047] Reference Figure 2 and Figure 3 There are multiple cleaning components arranged in an array in the horizontal direction, and a plurality of rollers 7 corresponding to the brush rollers 4 in the vertical direction are arranged in a transverse array at the bottom end of the loading plate 3, and each tensioning wheel 53 is located between two rollers 7 or two brush rollers 4 adjacent to itself.

[0048] Since the length of the saw band is uncertain, when it is tensioned, an appropriate number of cleaning components can be connected to the tensioning work according to the actual length of the saw band. At the same time, the roller 7 is used as the guiding and supporting component of the saw band. It can not only meet the cleaning needs of saw bands of different lengths, but also improve the cleaning effect of the saw band by means of multi-stage cleaning with the help of multiple cleaning components.

[0049] Reference Figure 3 and Figure 5 The rear ends of the outer arc surfaces of the feeding roller 32 and the supporting roller 7 are both provided with avoidance grooves 71, which are used to provide avoidance space for the saw teeth on the saw belt during the feeding process.

[0050] During the conveying process of the saw belt, the setting of the avoidance groove 71 can provide avoidance space for the saw teeth on the saw belt to prevent the saw teeth from being damaged by friction with other components and affecting subsequent use.

[0051] Reference Figure 3 and Figure 5 Two groups of upper and lower symmetrical limit assemblies 8 are arranged at the right end of the loading plate 3, and each limit assembly 8 includes two transmission wheels 81 rotatably connected to the right end of the loading plate 3, and a limit belt 82 is arranged between the two transmission wheels 81 in a belt drive manner. The limit belt 82 is arranged horizontally and corresponds to the position of the saw belt. The unwinding roller 33 or the winding roller 34 can drive the transmission wheel 81 adjacent to itself to rotate synchronously in the manner of bevel gear transmission.

[0052] Reference Figure 6 A limited step 9 is provided at the front end of the tensioning wheel 53, and the limited step 9 can abut against the end surface of the saw belt away from the saw teeth.

[0053] During the conveying process of the saw band, the transmission wheel 81 will rotate synchronously with the unwinding roller 33 and the winding roller 34, so that the displacement speed of the limiting belt 82 is consistent with the conveying speed of the saw band, and at the same time, the limiting belt 82 abuts against the saw teeth on the saw band, which can prevent the saw band from deviating backward without damaging the saw teeth; the limit step 9 can prevent the saw band from deviating forward after the tensioning wheel 53 enters the tensioning work of the saw band, thereby reducing the probability of the saw band running off course during the cleaning process.

[0054] The implementation principle of a cleaning device for saw belt processing in the embodiment of the present application is as follows:

[0055] When cleaning the saw band, since the saw band is usually in the shape of an endless band, personnel can first put the saw band on the outside of the whole formed by the feeding roller 32 and the two clamping rollers 36, so that the saw band is located in the gap between the unwinding roller 33 and the winding roller 34, and then use external auxiliary tooling to place the saw band inside the storage bin 12 to complete the initial feeding of the saw band.

[0056] Then, the linear drive 31 runs to drive the feeding roller 32 to move laterally until the feeding roller 32 moves to the left side of the tensioning wheel 53. At this time, the cylinder 51 drives the transition frame 52 and the tensioning wheel 53 to move backward, so that the tensioning wheel 53 is connected to the tensioning work of the saw belt, and then the tensioning wheel 53 is moved down through the cooperation of the first driving member 6 to put the saw belt in a tensioned state. At this time, part of the saw belt body is immersed in the cleaning liquid stored in the cleaning chamber 11 in advance, and the large diameter gear 54 will mesh with the small diameter gear 41, and at the same time, the part of the saw belt body pulled by the tensioning wheel 53 will abut against the brush roller 4.

[0057] Finally, the second driving member 37 operates to make the two clamping rollers 36 move away from each other, so that the two clamping rollers 36 respectively abut the upper and lower layers of the saw belt and press them to the outer surfaces of the unwinding roller 33 and the winding roller 34. In this state, when the two driving motors 35 operate to drive the unwinding roller 33 and the winding roller 34 to rotate synchronously, the position of the saw belt can be changed in a belt transmission manner, so that the brush roller 4 scrubs the surface of the saw belt.

[0059] S1, firstly, the saw belt is sleeved on the outside of the whole formed by the feeding roller 32 and the two pressing rollers 36, and the saw belt should be located in the gap between the unwinding roller 33 and the winding roller 34, and then the saw belt is placed in the storage bin 12 with the help of external auxiliary tooling;

[0060] S2, the feeding roller 32 is laterally displaced to the left side of the tensioning wheel 53 through the cooperation of the linear drive 31, and then the tensioning wheel 53 is coupled with the saw belt under the cooperation of the cylinder 51, and then the tensioning wheel 53 is moved downward through the cooperation of the first driving member 6 until the large diameter gear 54 is meshed with the small diameter gear 41, at which time part of the saw belt will be immersed in the cleaning liquid stored in advance in the cleaning chamber 11, and at the same time, part of the saw belt pulled by the tensioning wheel 53 will abut against the brush roller 4;

[0061] S3, the second driving member 37 operates to make the two clamping rollers 36 move away from each other, at this time, the two clamping rollers 36 will respectively abut the upper and lower layers of the saw belt and press them to the outer surfaces of the unwinding roller 33 and the winding roller 34, so that the saw belt can hold force normally during the subsequent transmission process, and then the two driving motors 35 operate to drive the unwinding roller 33 and the winding roller 34 to rotate synchronously, and the position of the saw belt changes in a belt transmission manner, so that the brush roller 4 scrubs the surface of the saw belt.

[0062] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0063] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
