Description

Technical Field

[0001] The utility model relates to the technical field of vertical sanding belt machines, in particular to a vertical sanding belt machine with an anti-collision function. Background Art

[0002] Vertical belt sanders mainly use cloth wheels, hemp wheels, flap wheels, nylon wheels, sanding belts and other polishing materials. They are used for sanding, grinding and polishing small and medium-sized hardware parts. During the workpiece processing process, the use of vertical belt sanders can better process the surface of the workpiece to ensure the production quality of the workpiece.

[0003] In the prior art, the Chinese patent with the authorization announcement number CN213970470U discloses a new type of vertical belt sander, which includes a frame, a motor, a rotating shaft, a driving wheel, a sanding belt, a hand-cranked sanding belt adjustment mechanism, an auxiliary wheel adjustment mechanism, a bearing seat, an auxiliary wheel and a guide wheel. The motor is reasonably arranged in the frame to ensure that the motor works in a clean environment, improve working stability and have a long service life; and the motor is located on the bottom surface of the frame, which effectively reduces gravity and has good operating stability; at the same time, a sleeve portion extending axially for a certain length is provided on the bearing seat, which brings convenience to the installation of the hand-cranked sanding belt adjustment mechanism and the protective cover, and effectively simplifies the frame structure; when the sanding belt deviates during operation, it can be quickly adjusted through the auxiliary wheel adjustment mechanism without stopping the machine, which is simple and convenient to operate, saving time and effort; when the sanding belt needs to be replaced or the tightness needs to be adjusted, it is only necessary to turn the handwheel of the hand-cranked sanding belt adjustment mechanism in the corresponding forward or reverse direction, and the operation process is simple and fast, which effectively improves work efficiency.

[0004] The above mechanism adjusts the tension of the abrasive belt by utilizing the hand wheel of the manually-cranked abrasive belt adjusting mechanism. In actual use, the tensioning mechanism is automatically adjusted to timely adapt to the changes of the abrasive belt itself during the processing. At the same time, during the grinding process, the workpiece needs to be continuously pushed and transported to achieve grinding. When the pushing force is large, the abrasive belt will be worn, affecting its service life. Utility Model Content

[0005] The purpose of the utility model is to provide a vertical belt sander with an anti-collision function to solve the problem in the background technology that during the grinding process, the workpiece needs to be continuously pushed and transported to achieve grinding, and when the pushing force is large, the sanding belt will be worn.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vertical belt sander with anti-collision function, comprising a mounting frame and a mounting rod connected at one end of the mounting frame by an elastic member, an active roller is sleeved on the outer side of the mounting rod, and a fixed roller is fixedly connected to the inside of the mounting frame by a rotating rod, a tensioning roller is slidably connected to the lower side of the active roller at one end of the mounting frame by a rotating rod, a grinding belt is sleeved on the outer side of the active roller, and the grinding belt is wound around the outer sides of the fixed roller and the tensioning roller;

[0007] A pneumatic telescopic rod is fixedly connected to one end of the mounting frame, and an anti-collision buffer mechanism for protecting the active roller is rotatably connected to one end of the pneumatic telescopic rod, the anti-collision buffer mechanism includes a first connecting rod, and the first connecting rod is rotatably connected to the output end of the pneumatic telescopic rod, and second connecting rods are sleeved on both sides of the outside of the mounting rod;

[0008] Both sides of the outer side of the tensioning roller are sleeved with mounting rings, and the lower end of the mounting ring is provided with a tensioning adjustment mechanism for adjusting the tension of the grinding belt.

[0009] Furthermore, a hinged rod is rotatably connected to one end between the first connecting rod and the second connecting rod, and the hinged rod is rotatably connected to the mounting frame.

[0010] Furthermore, one side of the mounting rod is rotatably connected to a driven gear, and one end of the mounting frame below the driven gear is fixedly connected to a driving gear via an elastic member, and a driving motor is provided on one side of the driving gear.

[0011] Furthermore, the output end of the driving motor is connected to the driving gear, and the driving gear and the driven gear are meshed with each other.

[0012] Furthermore, the tensioning mechanism includes an extension rod, and the extension rod is fixedly connected to the bottom end of the mounting ring, and the bottom end of the extension rod is fixedly connected to the fixing rod via a connecting spring.

[0013] Furthermore, the top end of the connecting spring is connected to the bottom end of the extension rod, and the bottom end of the connecting spring is connected to the bottom end inside the fixing rod.

[0014] Furthermore, slide rails are provided on both sides of one end of the mounting frame near the tensioning roller, and sliders matching the slide rails are fixedly connected on both sides of one end of the tensioning roller. The mounting frame and the tensioning roller are slidably connected through the slide rails and the sliders to form a sliding mechanism.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. During the grinding process, the grinding force needs to be adjusted according to different grinding requirements, and the workpiece needs to be pushed in the direction of the grinding belt. When the pushing force is too large, the grinding belt will be worn. Therefore, when this happens, the pneumatic telescopic rod will push the output end out, so that the first connecting rod is pushed in, and the articulated rod is connected to the inside of the mounting frame through the rotating rod, so that the angle of the articulated rod changes, and the second connecting rod at the upper end of the articulated rod is driven and moved to the inside of the mounting frame, so that the position of the active roller is driven and changed, so as to achieve buffer protection of the active roller during the processing process, and effectively extend the service life of the grinding belt;

[0017] Furthermore, the grinding belt will be loosened to a certain extent after long-term use. In order to ensure that the grinding belt can be used continuously without being completely worn out, it is necessary to use a tensioning mechanism to adjust the tension of the grinding belt so that the workpiece can be better polished with the grinding belt. The mounting ring is arranged on the outside of the rotating rod of the tensioning roller, and the connecting spring uses its own elastic force to adjust the extension length of the extension rod inside the fixed rod. When the grinding belt is relatively loose, the elastic force is used to drive the extension rod to move toward the inside of the fixed rod, thereby ensuring the tightness of the grinding belt, which is convenient for better polishing of the workpiece.

[0018] Furthermore, when adjusting the tension of the sanding belt, the contraction of the extension rod causes the mounting ring to drive the tension roller and the rotating rod to move downward, and one end of the tension roller is slidably connected to the mounting frame by a slide rail and a slider, so that the tension roller and the rotating rod can automatically adjust the position of the tension roller after the tension is adjusted, so that the whole can be used more stably;

[0019] 2. The driving motor rotates to drive the driving gear to rotate. When the driving gear rotates, it meshes with the driven gear, so that the driven gear drives the mounting rod and the driving roller to rotate, thereby realizing the overall operation of the device. In order to reduce the wear on the driving motor, the meshing of the driving gear and the driven gear can better realize the use and protection of the driving motor;

[0020] Furthermore, during the grinding process, it is necessary to adjust the rotation speed of the active roller according to different needs. By disassembling the driven gear and replacing it with a toothed disc with a different number of gears, the rotation speed of the active roller can be adjusted, so that the work efficiency can be higher when grinding the workpiece.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Embodiment 1:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 5The technical solution shown is to solve the problem that when the surface of the workpiece is processed, the grinding angle and position are adjusted according to the different states of the workpiece, which may cause damage to the device when the pushing force of the clamping device is too large: the vertical belt sander with anti-collision function discloses an anti-collision buffer mechanism, including a mounting frame 1 and a mounting rod 10 connected to one end of the mounting frame 1 by an elastic member, an active roller 3 is sleeved on the outer side of the mounting rod 10, and a fixed roller 2 is fixedly connected to the inside of the mounting frame 1 by a rotating rod, a tensioning roller 4 is slidably connected to the lower side of the active roller 3 at one end of the mounting frame 1 by a rotating rod, a grinding belt 5 is sleeved on the outer side of the active roller 3, and the grinding belt 5 is wound around the outer sides of the fixed roller 2 and the tensioning roller 4, and the inside of the mounting frame 1 One end of the mounting rod 10 is fixedly connected to a pneumatic telescopic rod 11, and one end of the pneumatic telescopic rod 11 is rotatably connected to an anti-collision buffer mechanism for protecting the active roller 3. The anti-collision buffer mechanism includes a first connecting rod 12, and the first connecting rod 12 is rotatably connected to the output end of the pneumatic telescopic rod 11. Second connecting rods 14 are sleeved on both sides of the outside of the mounting rod 10, and one end between the first connecting rod 12 and the second connecting rod 14 is rotatably connected to a hinged rod 13, and the hinged rod 13 is rotatably connected to the mounting frame 1, one side of the mounting rod 10 is rotatably connected to a driven gear 17, and one end of the mounting frame 1 below the driven gear 17 is fixedly connected to a driving gear 16 through an elastic member, and a driving motor 15 is provided on one side of the driving gear 16.

[0032] In this example, the adjustment mechanism can be driven to rotate by driving the motor 15, so that the mounting rod 10 rotates and drives the active roller 3 to rotate. The grinding belt 5 is sleeved on the outside of the fixed roller 2, the active roller 3 and the tensioning roller 4. When the active roller 3 rotates, the grinding belt 5 is driven and rotates around the outside of the fixed roller 2 and the tensioning roller 4. The workpiece is attached to the surface of the grinding belt 5, and the grinding process of the workpiece can be achieved. During the grinding process, the grinding force needs to be adjusted according to different grinding requirements, and the workpiece is moved in the direction of the grinding belt 5. When the pushing force is too large, the grinding belt 5 will be worn. Therefore, when this happens, the pneumatic telescopic rod 11 will push the output end out, so that the first connecting rod 12 is pushed forward, and the articulated rod 13 is rotatably connected to the inside of the mounting frame 1 through the rotating rod, so that the angle of the articulated rod 13 changes, and the second connecting rod 14 at the upper end of the articulated rod 13 is driven and moved to the inside of the mounting frame 1, so that the position of the active roller 3 is driven and changed, thereby realizing the buffer protection of the active roller 3 during the processing process, and effectively extending the service life of the grinding belt 5.

[0033] Embodiment 2:

[0034] like Figure 1 , Figure 2 , Figure 4 and Figure 7The technical solution shown is to solve the problem that the grinding belt 5 becomes loose after long-term use, resulting in poor grinding effect: the vertical sanding belt machine with anti-collision function discloses a tensioning mechanism, both sides of the outer side of the tensioning roller 4 are sleeved with mounting rings 9, and the lower end of the mounting ring 9 is provided with a tensioning adjustment mechanism for adjusting the tension of the grinding belt 5, the tensioning mechanism includes an extension rod 8, and the extension rod 8 is fixedly connected to the bottom end of the mounting ring 9, the bottom end of the extension rod 8 is fixedly connected to the fixing rod 6 through a connecting spring 7, the top end of the connecting spring 7 is connected to the bottom end of the extension rod 8, and the bottom end of the connecting spring 7 is connected to the bottom end of the inside of the fixing rod 6, slide rails 18 are provided on both sides of one end of the mounting frame 1 close to the tensioning roller 4, and sliders 19 matching the slide rails 18 are fixedly connected on both sides of one end of the tensioning roller 4, and the mounting frame 1 and the tensioning roller 4 are slidably connected by the slide rails 18 and the sliders 19 to form a sliding mechanism.

[0035] In this example, the grinding belt 5 will have a certain degree of looseness after long-term use. In order to ensure that the grinding belt 5 can be used continuously without being completely worn out, it is necessary to use a tensioning mechanism to adjust the tension of the grinding belt 5 so that the workpiece can be better polished with the grinding belt 5. The mounting ring 9 is sleeved on the outside of the rotating rod of the tensioning roller 4, and the connecting spring 7 uses its own elastic force to adjust the extension length of the extension rod 8 inside the fixed rod 6. When the grinding belt 5 is relatively loose, the elastic force is used to drive the extension rod 8 to move toward the inside of the fixed rod 6, thereby ensuring the tightness of the grinding belt 5 and facilitating better polishing of the workpiece.

[0036] Embodiment three:

[0037] like Figure 1 , Figure 2 and Figure 6 The technical solution shown is to solve the problem of needing to adjust the grinding speed according to different grinding requirements during use: the vertical belt sander with anti-collision function discloses an adjustment mechanism, one side of the mounting rod 10 is rotatably connected to a driven gear 17, and one end of the mounting frame 1 below the driven gear 17 is fixedly connected to a driving gear 16 through an elastic member, one side of the driving gear 16 is provided with a driving motor 15, the output end of the driving motor 15 is connected to the driving gear 16, and the driving gear 16 and the driven gear 17 are meshed with each other.

[0038] In this example, the driving motor 15 is driven to rotate the driving gear 16, and the driving gear 16 engages with the driven gear 17 during rotation, so that the driven gear 17 drives the mounting rod 10 and the active roller 3 to rotate, thereby realizing the overall operation of the device. In order to reduce the wear on the driving motor 15, the engagement of the driving gear 16 and the driven gear 17 can better realize the use and protection of the driving motor 15.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
