Description

Technical Field

[0001] This utility model relates to the field of hand-cranked cutting machine technology, and in particular to a hand-cranked cutting machine for stone cutting and processing. Background Technology

[0002] Stone, as a high-end building decoration material, is widely used in interior and exterior decoration design, curtain wall decoration, and public facility construction. In the stone production process, large blocks of stone are first divided into smaller pieces using large cutting equipment at the quarry. Then, hand-cranked cutting machines are used to further process the smaller stones, cutting them into the desired finished products. These hand-cranked cutting machines mainly consist of a servo motor and a cutting blade; workers directly push the machine by hand or crank the feed mechanism to move the cutting blade and adjust the cutting position.

[0003] Therefore, a hand-cranked cutting machine for stone cutting and processing is proposed.

[0004] Existing hand-cranked stone cutting machines have limitations in terms of the ease with which the cutting blade can move on the cutting table. This makes it difficult to manually move and adjust the cutting position of the stone, hindering flexible movement and adjustment during stone cutting. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing hand-cranked cutting machines, such as the inconvenience of moving the cutting blade on the cutting table, which makes it difficult to manually move and adjust the position of the stone cutting. Therefore, this invention proposes a hand-cranked cutting machine for stone cutting and processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Design a hand-cranked stone cutting machine, including a cutting table, a cutting mechanism mounted on the top of the cutting table, a connecting mechanism mounted on the bottom of the cutting mechanism, and a hand-cranked moving mechanism mounted on the bottom of the connecting mechanism; the cutting mechanism includes a cutting blade and a motor, a blade cover mounted on the outside of the cutting blade, the cutting blade being rotatably mounted on one side of the motor, and a support platform mounted on the bottom of the motor; the connecting mechanism includes a first connecting plate and a second connecting plate, the first connecting plate being fixed to the bottom of the support platform and slidably mounted on the top of the cutting table, with first connecting holes at its four corners, and a guide frame at the bottom of the first connecting plate. The second connecting plate is installed at the bottom of the cutting table, and has second connecting holes at its four corners. Bolts pass through the first and second connecting holes and are fitted with nuts to detachably and securely connect the first and second connecting plates. The hand-cranked moving mechanism includes a hand crank, a drive gear, a first rack, a driven gear, and a second rack. The hand crank passes through both ends of the drive gear. The first rack is engaged with the bottom end of the drive gear, the driven gear is engaged with the top end of the drive gear, and the second rack is engaged with the top end of the driven gear and fixedly installed at the bottom end of the second connecting plate.

[0008] Furthermore, a mounting frame is installed on the outer side of the top of the drive gear. The mounting frame is fixed to one end of the cutting table. The hand crank rotates through both sides of the mounting frame. The hand crank has an L-shaped structure and is horizontally positioned.

[0009] Furthermore, a first support plate is installed at the bottom end of the first rack, and a limit strip is fixed at the top of the first support plate and at the position on both sides of the first rack. A reinforcing rod is fixed at the four corners of the top of the first support plate, and the reinforcing rod is fixed at the bottom end of the cutting table.

[0010] Furthermore, a support rod is fixedly passed through the middle of the driven gear, and second support plates are rotatably installed at both ends of the support rod. The second support plates are fixed to the bottom end of the cutting table, the driven gear is horizontally arranged, and the second support plates are vertically arranged.

[0011] Furthermore, a cutting groove is provided on one side of the cutting table, a moving groove is provided on one side of the cutting groove, and limit grooves are provided on both sides of the moving groove. Both the limit groove and the moving groove are elongated structures and are horizontally arranged.

[0013] Furthermore, both the first connecting plate and the second connecting plate are rectangular plate structures and are horizontally arranged, while the bolts are vertically arranged.

[0014] Furthermore, both the first rack and the second rack are elongated structures and are horizontally arranged, the mounting frame is a U-shaped structure, the first support plate is a rectangular structure and is horizontally arranged, and the reinforcing rod is vertically arranged.

[0015] The hand-cranked stone cutting machine proposed in this utility model has the following advantages:

[0016] 1. This utility model, by installing a hand-cranked moving mechanism on the top of the cutting table, allows for flexible adjustment of the cutting mechanism's movement. Rotating the hand crank drives the drive gear to rotate, which in turn drives the first rack to move horizontally via a meshing transmission connection. This, in turn, drives the driven gear to rotate, which in turn drives the second rack to move horizontally via another meshing transmission connection. This, in turn, causes the second connecting plate and the first connecting plate to move horizontally along the moving groove and the limiting groove. Furthermore, the support platform drives the motor and the cutting blade to move on one side of the cutting groove, thus adjusting the position of the cutting blade above the cutting groove. Therefore, the cutting position of the cutting blade on the stone can be flexibly adjusted.

[0017] 2. This utility model is slidably installed on the upper and lower sides of the cutting table by means of bolts and nuts between the first connecting plate and the second connecting plate. Therefore, it is easy to disassemble the first connecting plate and the second connecting plate, and the cutting mechanism and the first and second racks can be disassembled and maintained. At the same time, the first connecting plate and the second connecting plate move along the moving groove and the limiting groove through the guide frame and bolts to maintain the stability of the cutting mechanism.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] For examples, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The figure shows a hand-cranked stone cutting machine, which includes a cutting table 1, a cutting mechanism mounted on the top of the cutting table 1, a connecting mechanism mounted on the bottom of the cutting mechanism, and a hand-cranked moving mechanism mounted on the bottom of the connecting mechanism.

[0026] In detail, the cutting mechanism includes a cutting blade 5 and a motor 3. A blade cover 4 is installed on the outside of the cutting blade 5. The cutting blade 5 is rotatably mounted on one side of the motor 3. A support platform 6 is installed at the bottom of the motor 3.

[0028] Furthermore, the connecting mechanism includes a first connecting plate 8 and a second connecting plate 20. The first connecting plate 8 is fixed to the bottom end of the support platform 6 and slidably installed on the top end of the cutting table 1. It has first connecting holes 25 at its four corners and a guide frame 26 at its bottom end. The second connecting plate 20 is installed on the bottom end of the cutting table 1 and has second connecting holes 24 at its four corners. Bolts 7 pass through the first connecting holes 25 and the second connecting holes 24 and are fitted with nuts to detachably and securely connect the first connecting plate 8 and the second connecting plate 20.

[0029] The cutting table 1 has a cutting groove 2 on one side, and a moving groove 11 is provided on one side of the cutting groove 2. Limiting grooves 10 are provided on both sides of the moving groove 11. Both the limiting groove 10 and the moving groove 11 are elongated structures and are horizontally arranged. The guide frame 26 is slidably inserted into the moving groove 11, and the bolt 7 is slidably passed through the limiting groove 10.

[0030] The first connecting plate 8 and the second connecting plate 20 are slidably installed on the upper and lower sides of the cutting table 1 by means of bolts 7 and nuts. Therefore, it is easy to disassemble the first connecting plate 8 and the second connecting plate 20, and the cutting mechanism and the first rack 14 and the second rack 19 can be disassembled and maintained. At the same time, the first connecting plate 8 and the second connecting plate 20 can move along the moving groove 11 and the limiting groove 10 through the guide frame 26 and the bolts 7, so as to maintain the stability and accuracy of the movement of the cutting mechanism.

[0031] Both the first connecting plate 8 and the second connecting plate 20 are rectangular plate structures and are horizontally arranged, while the bolts 7 are vertically arranged.

[0032] Finally, the hand-cranked moving mechanism includes a hand crank 15, a driving gear 13, a first rack 14, a driven gear 22, and a second rack 19. The hand crank 15 passes through both ends of the driving gear 13. The first rack 14 is engaged with the bottom end of the driving gear 13. The driven gear 22 is engaged with the top end of the driving gear 13. The second rack 19 is engaged with the top end of the driven gear 22 and is fixedly installed at the bottom end of the second connecting plate 20.

[0033] A mounting frame 12 is installed on the outer side of the top of the drive gear 13. The mounting frame 12 is fixed to one end of the cutting table 1. The hand crank 15 rotates through both sides of the mounting frame 12. The hand crank 15 has an L-shaped structure and is set horizontally.

[0034] A first support plate 18 is installed at the bottom end of the first rack 14. Limiting strips 16 are fixed at the top of the first support plate 18 and at the positions on both sides of the first rack 14. Reinforcing rods 17 are fixed at the four corners of the top of the first support plate 18. The reinforcing rods 17 are fixed at the bottom end of the cutting table 1.

[0035] A support rod 23 is fixedly passed through the middle of the driven gear 22. A second support plate 21 is rotatably installed at both ends of the support rod 23. The second support plate 21 is fixed at the bottom of the cutting table 1. The driven gear 22 is set horizontally, and the second support plate 21 is set vertically.

[0036] During the manual adjustment of the cutting mechanism, the hand crank 15 is turned to drive the drive gear 13 to rotate, which in turn drives the first rack 14 to move horizontally through the meshing transmission connection. The driven gear 22 is then driven to rotate through the meshing transmission connection, and the second rack 19 is driven to move horizontally through the meshing transmission connection. This causes the second connecting plate 20 and the first connecting plate 8 to move horizontally along the moving groove 11 and the limiting groove 10. In turn, the support platform 6 drives the motor 3 and the cutting blade 5 to move on one side of the cutting groove 2, thereby adjusting the position of the cutting blade 5 above the cutting groove 2. Therefore, the cutting position of the cutting blade 5 on the stone can be flexibly adjusted.

[0037] The first rack 14 and the second rack 19 are both elongated structures and are horizontally arranged. The mounting frame 12 is a U-shaped structure, the first support plate 18 is a rectangular structure and is horizontally arranged, and the reinforcing rod 17 is vertically arranged.

[0038] Working method: The hand-cranked moving mechanism is installed on the top of the cutting table 1. During the hand-cranked movement adjustment of the cutting mechanism, the hand crank 15 is rotated to drive the drive gear 13 to rotate, which drives the first rack 14 to move horizontally through the meshing transmission connection, and drives the driven gear 22 to rotate through the meshing transmission connection, which drives the second rack 19 to move horizontally through the meshing transmission connection. This causes the second connecting plate 20 and the first connecting plate 8 to move horizontally along the moving groove 11 and the limiting groove 10. Then, the support table 6 drives the motor 3 and the cutting blade 5 to move on one side of the cutting groove 2 to adjust the position of the cutting blade 5 above the cutting groove 2. Therefore, the cutting position of the cutting blade 5 on the stone can be flexibly adjusted.

[0039] The first connecting plate 8 and the second connecting plate 20 are slidably installed on the upper and lower sides of the cutting table 1 by means of bolts 7 and nuts. Therefore, it is easy to disassemble the first connecting plate 8 and the second connecting plate 20, and the cutting mechanism and the first rack 14 and the second rack 19 can be disassembled and maintained. At the same time, the first connecting plate 8 and the second connecting plate 20 can move along the moving groove 11 and the limiting groove 10 through the guide frame 26 and the bolts 7, so as to maintain the stability and accuracy of the movement of the cutting mechanism.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
