Description

Technical Field

[0001] The utility model relates to the field of wood board grinding devices, in particular to a grinding device with a protection mechanism. Background Art

[0002] A wood board sander is a machine used to sand the surface of wood. It is widely used in the woodworking industry, furniture manufacturing, architectural decoration and other fields. It can sand the rough parts of the wood surface to smooth it, improve the smoothness and beauty of the wood, and provide a good foundation for subsequent painting, veneer and other processing.

[0003] Existing wood board grinding machines are usually designed with multiple grinding discs and conveyor belts to achieve efficient grinding of the wood board surface. At the same time, in order to deal with the debris and dust generated during the grinding process, these devices also generally use negative pressure adsorption devices for collection and treatment. However, in the actual operation process, due to the vibration of the equipment itself, the friction of the conveyor belt on the wood board during transportation, and the influence of factors such as the external environment or the moisture of the wood board itself, some debris and dust may adhere to the surface of the conveyor belt and cannot be effectively collected by the negative pressure adsorption device. These debris and dust that have not been collected may be scattered to the outside of the equipment, such as the ground or other working areas, which not only increases the additional cleaning workload, but may also have a certain impact on the external environment. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a grinding device with a protective mechanism to solve the technical problem that some debris adheres to the surface of the conveyor belt and cannot be collected by the negative pressure adsorption device, causing the debris to fall to the ground or other workplaces outside.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grinding device with a protective mechanism, comprising a support frame, a conveyor belt, a movable plate and a workpiece, a cleaning mechanism is arranged on one side of the bottom of the conveyor belt, the cleaning mechanism comprises a negative pressure plate, a negative pressure groove is opened on one side of the top of the negative pressure plate, a mounting plate is arranged on the other side of the top of the negative pressure plate, a brush is arranged on the mounting plate, a negative pressure device is arranged on the top of the support frame, the negative pressure plate is connected with the negative pressure device through a negative pressure pipe, a plurality of grinding discs are arranged on the bottom of the movable plate, a dust suction pipe is arranged between the movable plate and the negative pressure device for collecting grinding debris of the workpiece under negative pressure.

[0006] By adopting the above technical solution, the negative pressure tube and the negative pressure device play a key role in the process of grinding the workpiece surface. They work together to form a negative pressure area with the negative pressure plate and the negative pressure groove on the bottom side of the conveyor belt, which can effectively absorb and fix the debris generated during the grinding process to prevent it from flying around.

[0007] Furthermore, the negative pressure groove is in the form of an elongated strip and is arranged parallel to the conveyor belt, and the negative pressure plate is fixedly connected to the support frame.

[0008] By adopting the above technical solution, the negative pressure groove with a long strip structure can cover a wider area of ​​the conveyor belt, thereby increasing the range of adsorbed debris and improving the cleaning efficiency. The parallel setting with the conveyor belt ensures that the negative pressure groove can closely fit the running path of the conveyor belt, making the adsorption effect more uniform and stable.

[0009] Furthermore, the mounting plate and the negative pressure plate are in a detachable connection structure, and the brush is used to clean the surface of the conveyor belt.

[0010] By adopting the above technical solution, the detachable connection structure makes the maintenance and replacement of the mounting plate and the brush extremely convenient. When the brush is worn or needs to be replaced, the staff can quickly and easily remove the mounting plate and perform necessary maintenance or replacement operations, thereby significantly improving the maintenance efficiency of the equipment.

[0011] Furthermore, a first motor is arranged on the top of the movable plate, and an output end of the first motor is connected to the grinding disc through a transmission belt.

[0012] By adopting the above technical solution, the first motor provides a stable and reliable power source for the grinding disc. Through the high-speed rotation of the motor, the grinding disc can obtain a sufficient rotation speed, thereby effectively grinding the surface of the workpiece.

[0013] Furthermore, a second motor is arranged on the inner side of the support frame, and the second motor is connected to the movable plate through a crank connecting rod.

[0014] By adopting the above technical solution, the movable plate has the ability to move laterally. Driven by the motor, the crank connecting rod can convert the rotational motion of the motor into linear reciprocating motion of the movable plate, thereby achieving uniform grinding of the workpiece surface and improving grinding efficiency and quality.

[0015] Furthermore, slide rails are provided between the two sides of the movable plate and the support frame.

[0016] By adopting the above technical solution, the slide rail provides a stable moving track for the movable plate, ensuring the stability and accuracy of the movable plate during lateral movement, which helps to maintain a constant distance and angle between the grinding tool and the workpiece surface, thereby improving the uniformity and quality of grinding.

[0017] Furthermore, fixed blocks are provided on both sides of the top of the conveyor belt, and a pressure roller is provided between the two fixed blocks to limit the position of the workpiece.

[0018] By adopting the above technical solution, the coordinated use of the fixed block and the pressure roller effectively limits the position of the workpiece on the conveyor belt. This limiting effect prevents the workpiece from being displaced or rolling during transportation and grinding, ensuring that the workpiece can pass through the grinding area stably, thereby improving the grinding accuracy and efficiency.

[0019] Furthermore, a hollow groove is provided on one side of the fixed block, a sliding block is slidably connected inside the hollow groove, and the sliding block is rotatably connected to the pressure roller.

[0020] By adopting the above technical solution, the empty groove and the sliding block are matched, and the position of the pressing roller can be flexibly adjusted according to the thickness or shape of the workpiece, so that the device can adapt to workpieces of different specifications, thereby improving the versatility and practicality of the equipment.

[0021] Furthermore, the fixed block is provided with an adjusting bolt, which is threadedly connected to the sliding block and is used to adjust the longitudinal position of the pressing roller.

[0022] By adopting the above technical solution, the setting of the adjusting bolt enables the staff to easily and accurately adjust the longitudinal position of the pressure roller. By rotating the adjusting bolt, the sliding block can slide up and down inside the empty groove, thereby driving the pressure roller to move to a suitable height to adapt to workpieces of different thicknesses or shapes.

[0023] Furthermore, two sets of limiting mechanisms are sleeved on the outer side of the pressure roller, and the limiting mechanisms include an upper limiting ring and a lower limiting ring, and the upper limiting ring and the lower limiting ring are detachably connected by mounting bolts.

[0024] By adopting the above technical solution, the lateral movement range of the workpiece on the conveyor belt can be effectively limited. The upper limit ring and the lower limit ring limit the workpiece from the top and bottom respectively, ensuring that the workpiece will not deviate from the predetermined position during the grinding process, thereby improving the grinding accuracy and stability.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model uses a cleaning mechanism. During the grinding process of the workpiece surface, the negative pressure tube and the negative pressure device first cause the negative pressure plate on one side of the bottom of the conveyor belt and the negative pressure groove to form a negative pressure area. This step effectively utilizes the negative pressure principle to quickly adsorb the debris generated during the grinding process into the negative pressure groove. At the same time, with the use of a brush, the debris adhered to the surface of the conveyor belt is thoroughly brushed off. These debris are then collected and processed by the negative pressure groove under negative pressure, thereby significantly improving the cleanliness of the conveyor belt surface and preventing the debris from falling to the ground or other working areas. This not only improves the practicality of the grinding device, but also reduces the cleaning burden on the external environment.

[0027] 2. The utility model gives the workpiece a certain position limitation through the pressing operation of the pressing roller. This limitation ensures that the workpiece can maintain a stable position when being transported on the conveyor belt, and will not be longitudinally offset or rolling due to the movement of the conveyor belt or other external forces. At the same time, the limiting mechanisms on both sides further prevent the workpiece from moving laterally. The limiting mechanism limits the workpiece from the top and bottom through the cooperation of the upper limiting ring and the lower limiting ring, effectively limiting the lateral range of movement of the workpiece, which avoids the position displacement of the workpiece during transportation and grinding, and improves the stability of workpiece grinding. This stability not only improves the quality of grinding, but also reduces the risk of equipment failure or workpiece damage due to position displacement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] 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. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:

[0035] A grinding device with a protective mechanism, such as Figure 1-Figure 4As shown, it includes a support frame 1, a conveyor belt 2, a movable plate 3 and a workpiece 4. A cleaning mechanism 8 is arranged on one side of the bottom of the conveyor belt 2. The cleaning mechanism 8 includes a negative pressure plate 801. A negative pressure groove 802 is opened on one side of the top of the negative pressure plate 801. A mounting plate 803 is arranged on the other side of the top of the negative pressure plate 801. A brush 804 is arranged on the mounting plate 803. A negative pressure device 11 is arranged on the top of the support frame 1. The negative pressure plate 801 is connected to the negative pressure device 11 through a negative pressure pipe 805. A plurality of grinding discs 5 are arranged on the bottom of the movable plate 3. In the process of grinding the surface of the workpiece 4, the negative pressure pipe 805 and the negative pressure device 1 1 plays a key role. They work together to form a negative pressure area between the negative pressure plate 801 and the negative pressure groove 802 on the bottom side of the conveyor belt 2, which can effectively absorb and fix the debris generated during the grinding process to prevent it from flying around. At the same time, with the use of the brush 804, the debris adhering to the surface of the conveyor belt 2 can be thoroughly brushed away. These debris are then quickly sucked into the negative pressure groove 802 and processed centrally. This process not only improves the cleanliness of the surface of the conveyor belt 2, but also prevents the debris from falling to the ground or other working areas, thereby reducing the cleaning burden on the external environment and improving the practicality of the grinding device.

[0036] See also Figure 2 The negative pressure groove 802 has a long strip structure and is arranged parallel to the conveyor belt 2. The negative pressure plate 801 is fixedly connected to the support frame 1. The negative pressure groove 802 with a long strip structure can cover a wider area of ​​the conveyor belt 2, thereby increasing the range of adsorbed debris and improving the cleaning efficiency. The parallel arrangement with the conveyor belt 2 ensures that the negative pressure groove 802 can fit closely to the running path of the conveyor belt, making the adsorption effect more uniform and stable. At the same time, the fixed connection between the negative pressure plate 801 and the support frame 1 ensures the stability of the entire negative pressure system. This connection method can prevent the negative pressure plate 801 from moving or shaking during operation, thereby ensuring that the negative pressure groove 802 always remains in the best position to maximize the adsorption effect.

[0037] See also Figure 2 The mounting plate 803 and the negative pressure plate 801 are in a detachable connection structure, and the brush 804 is used to clean the surface of the conveyor belt 2. The detachable connection structure makes the maintenance and replacement of the mounting plate 803 and the brush 804 extremely convenient. When the brush 804 is worn or needs to be replaced, the staff can quickly and easily remove the mounting plate 803 and perform necessary maintenance or replacement operations, thereby significantly improving the maintenance efficiency of the equipment. At the same time, the brush 804 is specifically used to clean the surface of the conveyor belt 2, and can thoroughly remove debris and dust attached to the conveyor belt, which not only ensures the cleanliness of the conveyor belt surface and improves the transmission efficiency, but also prevents debris and dust from polluting the working environment, thereby ensuring the cleanliness and safety of the production process.

[0038] See also Figure 1A first motor 701 is arranged on the top of the movable plate 3. The output end of the first motor 701 is connected to the grinding disc 5 through a transmission belt 6. The first motor 701 provides a stable and reliable power source for the grinding disc 5. Through the high-speed rotation of the motor, the grinding disc 5 can obtain a sufficient rotation speed, thereby effectively grinding the surface of the workpiece. At the same time, the transmission belt 6, as a key component connecting the first motor 701 and the grinding disc 5, has good transmission efficiency and stability. It can ensure that the power output by the motor is smoothly transmitted to the grinding disc 5, thereby realizing efficient grinding operation.

[0039] See also Figure 1 A second motor 702 is arranged on the inner side of the support frame 1, and the second motor 702 is connected to the movable plate 3 through a crank connecting rod 901, so that the movable plate 3 has the ability to move laterally. Through the drive of the motor, the crank connecting rod 901 can convert the rotational motion of the motor into a linear reciprocating motion of the movable plate 3, thereby achieving uniform grinding of the workpiece surface and improving the grinding efficiency and quality. At the same time, the crank connecting rod 901, as a key component connecting the second motor 702 and the movable plate 3, has the advantages of simple structure, reliable transmission, and convenient maintenance. It can effectively transmit the power of the motor and control the movement trajectory and speed of the movable plate, thereby ensuring the stability and controllability of the grinding process.

[0040] See also Figure 1 Slide rails 902 are arranged between the two sides of the movable plate 3 and the support frame 1. The slide rails 902 provide a stable moving track for the movable plate 3, ensuring the stability and accuracy of the movable plate 3 during the lateral movement, which helps to maintain a constant distance and angle between the grinding tool and the surface of the workpiece 4, thereby improving the uniformity and quality of grinding. At the same time, the setting of the slide rails 902 also enhances the structural rigidity and stability of the entire grinding device. It can withstand various forces and vibrations generated by the movable plate 3 and the grinding tools installed thereon, effectively preventing deformation or damage that may occur in the equipment during operation, and extending the service life of the equipment. Embodiment 2:

[0041] See also Figure 1 , Figure 3 , Figure 4 Fixed blocks 12 are provided on both sides of the top of the conveyor belt 2, and a pressure roller 15 is provided between the two fixed blocks 12 to limit the position of the workpiece 4. The coordinated use of the fixed blocks 12 and the pressure roller 15 effectively limits the position of the workpiece 4 on the conveyor belt 2. This limiting effect prevents the workpiece 4 from being displaced or rolled during transportation and grinding, ensures that the workpiece 4 can stably pass through the grinding area, and improves the grinding accuracy and efficiency. At the same time, this helps to protect the integrity and surface quality of the workpiece and improves the qualified rate of the finished grinding product.

[0042] See also Figure 1 , Figure 3 , Figure 4 A hollow groove 13 is provided on one side of the fixed block 12, and a sliding block 14 is slidably connected inside the hollow groove 13. The sliding block 14 is rotatably connected to the pressure roller 15. The cooperation between the hollow groove 13 and the sliding block 14 allows the position of the pressure roller 15 to be flexibly adjusted according to the thickness or shape of the workpiece 4, so that the device can adapt to workpieces 4 of different specifications, thereby improving the versatility and practicality of the equipment. At the same time, the rotational connection between the sliding block 14 and the pressure roller 15 ensures that the pressure roller 15 can rotate smoothly, thereby reducing the friction resistance between the workpiece and the workpiece, which not only helps to protect the workpiece surface from scratches or wear, but also improves the efficiency of the conveyor belt in transporting the workpiece 4, further improving the efficiency and quality of the overall grinding operation.

[0043] See also Figure 1 , Figure 3 , Figure 4 The fixed block 12 is provided with an adjusting bolt 16, which is threadedly connected to the sliding block 14 for adjusting the longitudinal position of the pressure roller 15. The setting of the adjusting bolt 16 enables the staff to easily and accurately adjust the longitudinal position of the pressure roller 15. By rotating the adjusting bolt 16, the sliding block 14 can slide up and down inside the empty groove 13, thereby driving the pressure roller 15 to move to a suitable height to adapt to workpieces of different thicknesses or shapes. At the same time, since the adjusting bolt 16 and the sliding block 14 are threadedly connected, this connection method has good self-locking performance, which can ensure that after the position of the pressure roller 15 is adjusted, its position can remain stable and will not move due to equipment vibration or other external forces, which helps to improve the accuracy and stability of the grinding operation.

[0044] See also Figure 1 , Figure 3 , Figure 4 Two sets of limiting mechanisms 17 are sleeved on the outer side of the pressure roller 15, and the limiting mechanism 17 includes an upper limiting ring 1701 and a lower limiting ring 1702, and the upper limiting ring 1701 and the lower limiting ring 1702 are detachably connected by mounting bolts 1703, which can effectively limit the lateral movement range of the workpiece 4 on the conveyor belt 2, and the upper limiting ring 1701 and the lower limiting ring 1702 limit the workpiece 4 from the top and bottom respectively, to ensure that the workpiece will not deviate from the predetermined position during the grinding process, thereby improving the grinding accuracy and stability, at the same time, the upper limiting ring 1701 and the lower limiting ring 1702 are detachably connected by mounting bolts 1703, so that the limiting mechanism 17 can be quickly installed and disassembled according to actual needs, which not only facilitates the maintenance and replacement of the equipment, but also can adjust the position or quantity of the limiting mechanism 17 according to the size and shape of different workpieces 4, further improving the adaptability and flexibility of the equipment.

[0045] The implementation principle of the utility model is as follows: first, the workpiece 4 is placed on the conveyor belt 2, and the workpiece 4 is pressed by the pressing roller 15 to give the workpiece 4 a certain position limitation, and at the same time, the limiting mechanisms 17 on both sides are used to prevent the workpiece 4 from being horizontally limited, so as to avoid the workpiece 4 from being positionally offset during the transportation and grinding process, and improve the grinding stability of the workpiece 4. As the workpiece 4 gradually moves, the first motor 701 on the top rotates the multiple grinding discs 5 through the transmission belt 6, and grinds the surface of the workpiece 4. At this time, the second motor 702 on one side causes the movable plate 3 to repeatedly move horizontally through the crank connecting rod 901 and the slide rail 902, so as to improve the grinding efficiency of the grinding device on the workpiece, until the entire workpiece 4 is polished and the grinding operation is completed;

[0046] During the process of grinding the surface of the workpiece 4, the negative pressure plate 801 and the negative pressure groove 802 on the bottom side of the conveyor belt 2 become negative pressure areas through the negative pressure tube 805 and the negative pressure device 11, and the brush 804 is used to brush away the debris adhering to the surface of the conveyor belt 2, and then the negative pressure groove 802 with negative pressure is negatively pressurized for collection and treatment, thereby improving the cleanliness of the surface of the conveyor belt 2, preventing the debris adhering to the surface of the conveyor belt 2 from falling to the ground or other working areas, thereby improving the practicability of the grinding device and reducing the cleaning burden of the external environment.

[0047] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
