Description

Technical Field

[0001] The present application relates to the technical field of sheet processing, and in particular to a sheet surface cutting device. Background Art

[0002] Sheets are widely used in many technical fields such as construction and furniture. After the sheet processing is completed, the edges of the sheet need to be cut to make the sheet consistent and ensure the aesthetics of the edges.

[0003] Existing sheet cutting equipment includes a frame, a conveying plate, a blade, and a driving member. The conveying plate is slidably arranged on the frame and is used to place the sheet. The blade is rotatably installed on the frame, and the driving member is used to drive the blade to rotate. The sheet is placed on the conveying plate, and then the conveying plate conveys the sheet to the blade for cutting.

[0004] The blade is exposed to the outside, and there is a risk of contact with the staff during idle or use, posing a safety hazard and reducing the safety during cutting. At the same time, when the blade cuts the sheet, it will exert a force on the sheet, causing the sheet to easily displace and reducing the cutting quality of the sheet. Summary of the Invention

[0005] In order to improve the safety and cutting quality during sheet cutting, the present application provides a sheet surface cutting device.

[0006] A sheet surface cutting device provided by the present application adopts the following technical solutions: A sheet surface cutting device includes a frame, a conveying plate, a blade, and a driving member, and further includes a protective positioning structure for covering and protecting the blade and positioning the sheet. The protective positioning structure includes: A protective cover, which is slid up and down on the frame through a moving rod, and the moving rod is located outside the sheet; A plurality of rollers, which are rotatably installed at the bottom of the protective cover; An elastic component, which is connected to the protective cover and makes the rollers abut against the conveying plate for positioning and makes the blade located inside the protective cover for protection; A pushing component, which is arranged on the conveying plate. The movement of the conveying plate drives the pushing component to contact the protective cover and cooperate with the elastic component to drive the protective cover and the rollers to move up and down. When the conveying plate approaches the blade, the protective cover and the rollers move up. After the sheet moves under the rollers, the pushing component disengages from the protective cover and makes the rollers move under the action of the elastic component and press against the sheet for positioning.

[0007] By adopting the above technical solution, the protective cover drives a plurality of rollers to press against the conveying plate for positioning under the action of the elastic component, and the blade is located inside the protective cover for protection, reducing the risk of contact between the staff and the blade. Meanwhile, when the plate needs to be cut, the plate is placed on the conveying plate for positioning, and then the conveying plate moves to drive the plate close to the blade. At the same time, the conveying plate drives the pushing component close to the protective cover, and the pushing component pushes the protective cover upward, so that the rollers move above the plate. After the plate moves below the rollers, the pushing component disengages from the protective cover under the push of the conveying plate. The plurality of rollers press against the plate under the action of the elastic component for positioning, and the movement of the plate drives the rollers to rotate. Therefore, the plurality of rollers can position the position of the plate until the plate cutting is completed. The conveying plate drives the pushing component to move back, and the pushing component continues to push the protective cover upward and then move back, so that the rollers press against the conveying plate again, and the blade is located inside the protective cover.

[0008] By locating the blade inside the protective cover for protection and positioning through the elastic component, and during processing, the protective cover can still keep the blade inside the protective cover for protection, reducing the risk of harm to the staff and the potential safety hazard. At the same time, the protective cover can position the plate, and the positioning position is just at the cutting position of the blade, greatly improving the positioning effect of the plate, and at the same time improving the safety and cutting quality during plate cutting.

[0009] The protective cover can also make the dust generated by cutting located inside the protective cover, reducing the risk of dust escaping into the environment and causing pollution. And the protective cover is vertically slidably installed on the frame. Compared with rotation, it can also protect the blade. However, for a rotating protective cover, when the plate moves for cutting, it is easy to interfere with the rotating connection between the protective cover and the frame, thus greatly limiting the cutting size of the plate. While the vertically sliding protective cover will not have an adverse effect on the size of the plate, enabling the protective cover to protect the blade while also increasing the adaptability range of the blade to the size of the plate.

[0010] Optionally, a fixing block is arranged on the outer side wall of the protective cover, and the elastic component includes: A fixing rod, arranged on the frame and slidably passing through the fixing block; A fixing disk, threadedly connected to the fixing rod and located above the fixing block; A spring, sleeved on the fixing rod and pressing against the fixing block and the fixing disk and used to drive the protective cover to maintain a downward movement tendency By adopting the above technical solution, the moving rod can guide the movement of the protective cover. The spring pushes the fixed block and the protective cover downward, so that the roller presses against the conveying plate, and the blade is located inside the protective cover for protection. The pushing component contacts the protective cover, thereby pushing the protective cover upward, so that the roller presses against the plate for positioning. In this way, the blade can be protected and the plate can be positioned. At the same time, after removing the fixed disk from the fixed rod, the spring can be replaced. Then, the spring is sleeved on the fixed rod, and then the fixed disk is threadedly connected to the fixed rod, so that the fixed disk presses against the spring. Moreover, the fixed disk can be screwed to adjust the pressure of the roller on the frame and the plate, further improving the protection effect on the blade and the positioning effect on the plate, and improving the safety and cutting quality during plate cutting.

[0011] Optionally, the pushing component includes: A pushing block is arranged on the conveying plate and is provided with a first pushing surface, a horizontal surface, and a second pushing surface at intervals along the moving direction of the conveying plate. The first pushing surface, the horizontal surface, and the second pushing surface are respectively inclined upward, horizontally extended, and inclined downward along the sliding direction of the conveying plate. A supporting wheel is rotatably installed at the bottom end of the moving rod; when the plate approaches the blade, the supporting wheel rolls onto the first pushing surface and is used to push the moving rod and the protective cover upward; when the supporting wheel rolls on the horizontal surface, the moving rod and the protective cover remain stationary and the plate moves below the roller; when the supporting wheel rolls on the second pushing surface, the moving rod and the protective cover move downward and press against the plate, and then the supporting wheel disengages from the second pushing surface.

[0012] By adopting the above technical solution, the movement of the conveying plate drives the pushing block to approach the moving rod, so that the supporting wheel rolls on the first pushing surface. With the movement of the pushing block, the first pushing surface pushes the protective cover and the roller upward above the plate. As the pushing block moves, the supporting wheel rolls onto the horizontal surface, and the roller and the protective cover remain stationary, so that the plate moves below the roller. As the pushing block moves, the supporting wheel rolls onto the second pushing surface and then disengages from the second pushing surface, and the roller moves downward under the elastic force of the elastic component and presses against the plate for positioning. The movement of the plate causes the roller to rotate, and the blade rotates to cut the plate.

[0013] After the plate cutting is completed, the conveying plate moves back. The pushing block makes the protective cover move upward and then downward, so that the roller presses against the conveying plate for positioning, and at the same time the plate moves outside the protective cover, thereby realizing driving the protective cover to protect the blade and position the plate, and improving the safety and cutting quality during plate cutting.

[0014] Optionally, a positioning mechanism for positioning the plate is arranged on the conveying plate. The positioning mechanism includes: A plurality of positioning blocks are arranged on the conveying plate and abut against the adjacent two side walls of the plate for positioning; A pressing assembly is arranged on the positioning block and presses against the plate for positioning.

[0015] By adopting the above technical solution, the plate is placed on the conveying plate, and the adjacent two side walls of the plate are pushed to abut against a plurality of positioning blocks for positioning. Then, the pressing assembly is activated to press against the plate for positioning, thereby further improving the positioning effect of the plate and the cutting quality of the plate.

[0016] Optionally, the pressing assembly includes: A pressing plate is rotatably installed on the positioning block; An elastic member is arranged on the positioning block and is used for positioning the pressing plate under the elastic action, so that the pressing plate presses against the plate for positioning or keeps the pressing plate away from the plate.

[0017] By adopting the above technical solution, the pressing plate is rotated to press against the plate for positioning, so that the positioning of the plate can be realized. When the plate needs to be removed, after the pressing plate is toggled away from the plate, the elastic member continues to position the pressing plate, thereby facilitating the positioning of the plate and the removal of the plate.

[0018] Optionally, an absorption mechanism for absorbing impurities in the protective cover is arranged on the frame, and the absorption mechanism includes: An absorption box is arranged on the frame; A connecting component is arranged on the protective cover and is slidably connected to the absorption box; A collection component is arranged on the absorption box; A blower is arranged on the absorption box and enables the dust in the protective cover to be transferred to the collection component through the connecting component for collection.

[0019] By adopting the above technical solution, when the roller of the protective cover presses against the plate for positioning and the blade cuts the plate, the dust generated is located in the protective cover. The blower is started, so that the dust generated during cutting enters the collection component through the connecting component for collection. At the same time, the connecting component can realize avoidance when the protective cover moves, so that the dust can be absorbed and transported while the protective cover moves, thereby further reducing the risk of dust escaping into the external environment and polluting the environment.

[0020] Optionally, the connecting component includes: A fixed pipe is arranged on the absorption box; An absorption pipe is arranged on the protective cover and is slidably connected to the fixed pipe.

[0021] By adopting the above technical solution, the movement of the protective cover activates the driving absorption tube to be slidably connected to the fixed tube, so as to realize the sliding of the protective cover and also absorb dust at the same time.

[0022] Optionally, a collection hole is formed in the absorption box, and the collection assembly includes: A collection frame, which is slidably installed on the collection hole and is evenly provided with a plurality of filter holes and is used for collecting dust; A collection plate, which is arranged on the collection frame and abuts against the collection box for positioning.

[0023] By adopting the above technical solution, dust is moved into the collection frame for collection, the collection plate abuts against the collection box for positioning, and at the same time, pulling the collection plate can remove the collection frame for cleaning, thereby improving the dust collection effect.

[0024] Optionally, an inclined guide plate is arranged on the frame, and a collection box for collecting waste is placed below the guide plate on the frame.

[0025] By adopting the above technical solution, the waste falls on the guide plate, and the waste moves into the collection box under the action of gravity for collection, thereby realizing the automatic collection of waste.

[0026] Optionally, the roller is provided with an elastic layer with elasticity, and the waste cut from the plate moves into the collection box under the thrust of the elastic layer and the guiding action of the guide plate for collection.

[0027] By adopting the above technical solution, the elastic layer on the roller presses against the plate for positioning, and as the blade cuts the plate, finally after the waste on the plate is cut, the compressed elastic layer generates a downward thrust on the waste, causing the plate to fall on the guide plate, and then the plate falls into the collection box under the guiding action of the inclined guide plate for collection, thereby improving the convenience of waste collection. Therefore, the roller and the elastic layer can position the plate and improve the convenience of waste collection when the plate is being processed.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. By protecting the blade inside the protective cover, and the roller presses against the plate for positioning under the action of the elastic force assembly, and at the same time, the protective cover can continue to protect the blade inside the protective cover, reducing the risk of harm to the staff and reducing potential safety hazards. At the same time, the protective cover can position the plate, and the positioning position is just at the cutting position of the blade, greatly improving the positioning effect of the plate, and at the same time improving the safety and cutting quality during plate cutting.

[0029] 2. The dust is located inside the protective cover, reducing the risk of dust escaping into the environment and causing pollution. Moreover, the protective cover is installed on the frame in a vertical sliding manner, which can also protect the blade relative to rotation. A rotating protective cover is likely to cause interference between the plate and the connection between the protective cover and the rotating frame during plate cutting, thus greatly limiting the cutting size of the plate. However, a vertically sliding protective cover will not have an adverse impact on the size of the plate, enabling the protective cover to protect the blade while also increasing the adaptability range of the blade to the size of the plate.

The conveying plate 11 is horizontally slidably installed on the upper surface of the frame 1, and the moving direction of the conveying plate 11 is perpendicular to the axis direction of the blade 12. A driving structure for driving the conveying plate 11 is provided on the frame 1. The driving structure can adopt a motor screw-nut structure. The above structures are prior art and will not be elaborated here.

[0036] An inclined downward guide plate 13 is fixedly installed on the frame 1 and on the side of the blade 12 away from the conveying plate 11. The highest point of the guide plate 13 is located on the side close to the conveying plate 11 and is flush with the upper surface of the conveying plate 11; A collection box 14 is placed on the frame 1, and the collection box 14 is located below the guide plate 13. The waste materials cut from the sheet 17 by the blade 12 fall on the guide plate 13 and fall into the collection box 14 under the guiding action of the guide plate 13 for collection.

[0037] The protective positioning structure 2 includes a protective cover 21, a plurality of rollers 22, an elastic component 3, and a pushing component 4. A horizontal support plate 16 is fixedly installed on the frame 1 and on the side of the conveying plate 11 close to the guide plate 13. The support plate 16 is located at the position of the blade 12 and below the guide plate 13; The protective cover 21 is vertically slidably arranged on the support plate 16 through a moving rod 15. The protective cover 21 is located directly above the blade 12. A fixed block 23 is fixedly installed on the side wall of the protective cover 21 facing away from the conveying plate 11. The fixed block 23 includes a vertical section 24 and a horizontal section 25 connected to each other. The vertical section 24 is fixedly installed on the side wall of the protective cover 21 facing away from the conveying plate 11 and is arranged vertically downward. The horizontal section 25 is located at the bottom end of the vertical section 24 and extends horizontally above the support plate 16; One end of the moving rod 15 is fixedly installed on the lower surface of the horizontal section 25. The moving rod 15 vertically slides through the support plate 16 and its bottom end vertically extends below the support plate 16. The moving rod 15 is located outside the sheet 17 and on the side of the sheet 17 close to the guide plate 13.

[0038] A plurality of rollers 22 are rotatably installed on the lower surface of the protective cover 21 and on the side of the blade 12 close to the conveying plate 11 and the guide plate 13. The elastic component 3 is connected to the support plate 16 and the protective cover 21. When no sheet 17 is placed, the plurality of rollers 22 are pressed against the upper surface of the conveying plate 11 under the elastic force of the elastic component 3. After the sheet 17 is placed, the plurality of rollers 22 are pressed against the sheet 17 under the action of the elastic component 3 for positioning.

[0039] An elastic layer, which is elastic and used for protection, is coaxially arranged on the outer side wall of the roller 22. The elastic layer presses against the plate 17 for positioning. When the waste material cut from the plate 17 falls off, the compressed elastic layer can generate a downward thrust on the waste material, so that the plate 17 slides on the diversion plate 13 until it falls into the collection box 14 for collection.

[0040] The elastic force assembly 3 includes a fixed rod 31, a fixed disk 32 and a spring 33. The fixed rod 31 is fixedly installed on the upper surface of the support plate 16, and the fixed rod 31 and the moving rod 15 are arranged at intervals. The fixed rod 31 vertically slides through the horizontal section 25; the fixed disk 32 is threadedly connected to the fixed rod 31 and is located above the horizontal section 25. The spring 33 is sleeved on the fixed rod 31 and its two ends are pressed against the horizontal section 25 and the fixed disk 32 for positioning. The spring 33 pushes the fixed block 23 and the protective cover 21 downward, so that the roller 22 presses against the conveying plate 11 for positioning, and the blade 12 is located inside the protective cover 21, so as to protect the exposed blade 12. Or, the roller 22 presses against the plate 17 for positioning, so as to reduce the risk of the staff touching the blade 12, and improve the positioning effect of the plate 17, and improve the safety and cutting quality.

[0041] Refer to Figure 2 and Figure 3 The pushing assembly 4 includes a pushing block 41 and a supporting wheel 42. A pushing rod 18 extending below the support plate 16 is fixedly installed on the lower surface of the conveying plate 11 near one end of the blade 12. The pushing block 41 is fixedly installed at the bottom end of the pushing rod 18 and is located below the moving rod 15.

The first pushing surface 43, the horizontal surface 44 and the second pushing surface 45 are respectively inclined upward, horizontally extended and inclined downward along the moving direction of the conveying plate 11. The height of the two ends of the horizontal surface 44 connected to the first pushing surface 43 and the second pushing surface 45 is the highest.

[0042] The supporting wheel 42 is rotatably installed at the bottom end of the moving rod 15. The conveying plate 11 moves to drive the sheet 17 close to the blade 12, so that the supporting wheel 42 rolls onto the first pushing surface 43 and is used to push the moving rod 15 and the protective cover 21 upward until the protective cover 21 moves above the sheet 17. As the conveying plate 11 moves, the supporting wheel 42 moves on the horizontal plane 44, and the protective cover 21 and the plurality of rollers 22 remain stationary, so that the sheet 17 moves below the protective cover 21 and the plurality of rollers 22. Then the supporting wheel 42 moves onto the second pushing surface 45 until it disengages from the second pushing surface 45, so that the supporting wheel 42, the moving rod 15 and the protective cover 21 move downward, and the rollers 22 press against the sheet 17 for positioning. At the same time, the sizes of the first pushing surface 43, the horizontal plane 44 and the second pushing surface 45 are designed according to actual needs, so that the rollers 22 move upward above the sheet 17 and then move downward to press against the sheet 17. Moreover, during the operation process, the earlier the rollers 22 press against the sheet 17 for positioning, the better.

Two recessed portions 55 and a protruding portion 56 connecting the two recessed portions 55 are arranged at intervals on the elastic member 54 along the rotation direction of the pressing plate 53. When the pressing plate 53 is in a horizontal state and a state of being away from the conveying plate 11, it presses against the two recessed portions 55 for positioning, so that when the pressing plate 53 is in a horizontal state, it presses against the sheet 17 for positioning. Or, when the pressing plate 53 is in a state of being away from the conveying plate 11, it is convenient to pick up the sheet 17 at this time.

[0045] Referring to Figure 1 and Figure 5 On the frame 1, an absorption mechanism 6 for absorbing impurities inside the protective cover 21 is provided. The absorption mechanism 6 includes an absorption box 61, a connection component 7, a collection component 8 and a blower 62. The absorption box 61 is fixedly installed on the frame 1.

Air passes through the filter holes, and the impurities move into the collection frame 81 for collection. At the same time, the collection frame 81 can be removed to clean the impurities, and then the collection frame 81 is horizontally slidably installed on the collection hole 64, and the collection plate 82 is pushed to abut against the collection box 14 for positioning, improving the collection effect of the impurities.

[0049] The working principle of the embodiment of the present application is as follows: Place the plate 17 on the conveying plate 11, and abut the adjacent side walls of the plate 17 against a plurality of positioning blocks 51. Rotate the pressing plate 53 close to the plate 17, and the pressing plate 53 presses against the plate 17 under the action of the elastic member 54 for positioning. The conveying plate 11 moves to drive the plate 17 close to the blade 12. At the same time, the conveying plate 11 moves to drive the pushing block 41 close to the moving rod 15. The pushing block 41 contacts the moving rod 15 to push the protective cover 21 and the roller 22 to move upward above the plate 17. The plate 17 moves below the roller 22, and then the roller 22 moves backward and presses against the plate 17 under the action of the spring 33 for positioning, so as to realize the positioning of the plate 17.

[0050] The blade 12 cuts the sheet 17, and the impurities after cutting stay in the protective cover 21. At the same time, the fan 62 is started, so that the impurities are moved to the collection box 81 for collection, thereby realizing the collection of impurities. The waste materials after cutting on the sheet 17 are moved to the collection box 14 for collection under the thrust of the elastic layer and the guidance of the deflector 13, thereby realizing the cutting of the sheet 17. Then the conveying plate 11 moves back, so that the sheet 17 is separated from the roller 22. The roller 22 moves down under the action of the spring 33 and then presses against the conveying plate 11 for positioning. The blade 12 is located in the protective cover 21. Finally, the pressing plate 53 is pushed away from the sheet 17, and then the sheet 17 to be cut can be replaced, thereby reducing the risk of injury caused by the contact between the staff and the blade 12, improving the positioning effect of the sheet 17, and improving the safety and cutting quality of the cutting of the sheet 17.
