Each rotating column has a pair of limiting rings on its side wall for guiding the protrusions on the waterstop. The side wall of the rotating column has symmetrical limiting grooves. The inner wall of the limiting ring extends with an extension block that matches the limiting groove. The extension block protrudes from the end of the limiting ring. A locking element that fits with the limiting groove and stops the limiting ring is embedded on the side wall of the extension block away from the rotating column.

[0006] Furthermore, the extension blocks on the paired limiting rings extend to the side that is far apart from each other, and the locking element is a locking bolt; An embedding hole is provided on the side wall of the extension block away from the rotating column, and a threaded hole communicating with the embedding hole is provided on the side wall of the extension block close to the rotating column. The threaded post of the locking member is located inside the threaded hole, and the head of the locking member is located inside the embedding hole.

[0007] Furthermore, the rotating column sidewall is provided with a stop groove that communicates with the limiting groove, and the width of the stop groove is greater than the inner diameter of the threaded hole.

[0008] Furthermore, the top of the base plate is symmetrically provided with mounting grooves on both sides of the cutting blade, and a conveyor belt is provided inside the mounting groove. The upper end face of the conveyor belt is flush with the upper end face of the base plate, and the edges of the inner wall of the mounting groove are rounded.

[0009] Furthermore, a clearance groove is provided at the top of the base plate at a position corresponding to the cutting blade to allow the cutting blade to pass. The drive cutting assembly includes a U-shaped support plate disposed on the top of the base plate with its opening facing downwards, and a lifting electric push rod connected to the cutting blade is disposed on the top of the U-shaped support plate.

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figure 1 As shown, this utility model provides a technical solution: a cutting device for producing waterstops, comprising: A base plate 1 is provided, a cutting blade 7 is provided above the base plate 1, and a driving cutting assembly 8 for driving the cutting blade 7 to cut the waterstop is provided on the top of the base plate 1. A pair of rotating columns 4 are respectively located on both sides of the cutting blade 7 above the base plate 1. Each rotating column 4 has a vertical plate 3 connected to the top of the base plate 1 at both ends. Each rotating column 4 has a pair of limiting rings 5 ​​on its side wall for guiding the protrusions on the waterstop. The side wall of the rotating column 4 has symmetrically opened limiting grooves 41. The inner wall of the limiting ring 5 extends with an extension block 51 that matches the limiting groove 41. The extension block 51 protrudes from the end of the limiting ring 5. The side wall of the extension block 51 away from the rotating column 4 has a locking member 9 that fits with the limiting groove 41 to stop the limiting ring 5. This design uses the gap between the paired limiting rings 5 ​​to fit against the opposite sides of the protrusions on the waterstop, thus guiding and limiting the waterstop during transport and preventing it from tilting. This provides a good anti-tilting effect and improves cutting quality. The locking element 9 can fix the adjusted limiting rings 5, improving the stability of the connection between the limiting rings 5 ​​and the rotating column 4, and enhancing the stability of the limiting and guiding of the protrusions on the waterstop.

[0015] Reference Figure 2 , Figure 3 and Figure 5 The extension blocks 51 on the paired limiting rings 5 ​​extend to the side that is far apart from each other, and the locking element 9 is a locking bolt; An insertion hole 511 is provided on the side wall of the extension block 51 away from the rotating column 4, and a threaded hole 512 communicating with the insertion hole 511 is provided on the side wall of the extension block 51 near the rotating column 4. The threaded post of the locking member 9 is located inside the threaded hole 512, and the head of the locking member 9 is located inside the insertion hole 511. This design allows the locking member 9 to be threadedly connected to the threaded hole 512, facilitating the locking member 9 to fit against the inner wall of the limiting groove 41 along the threaded hole 512, thereby stopping the limiting ring 5.

[0016] Reference Figure 3 and Figure 5 The rotating column 4 has a stop groove 42 on its side wall that communicates with the limiting groove 41. The width of the stop groove 42 is greater than the inner diameter of the threaded hole 512. This design connects the stop groove 42 to the end of the locking member 9 to stop the limiting ring 5 without damaging the threaded column on the locking member 9.

[0017] Reference Figure 1 The base plate 1 has symmetrical mounting grooves 1002 on both sides of the cutting blade 7. A conveyor belt 2 is installed inside the mounting groove 1002, with its upper surface flush with the upper surface of the base plate 1. The edges of the inner wall of the mounting groove 1002 are rounded. This design facilitates the transport of the waterstop through the conveyor belt 2. The paired limiting rings 5 ​​guide and limit the waterstop, preventing tilting during transport and improving subsequent cutting quality. The conveyor belt 2 contains a driving roller and multiple driven rollers, which are rotatably connected to the base plate 1. A drive motor connected to the driving roller is located on the side wall of the base plate 1, facilitating the transport of the conveyor belt 2. The axis of one of the driven rollers is aligned vertically with the axis of the rotating column 4, improving the stability of the waterstop transport.

[0018] Reference Figure 1 and Figure 4 A clearance groove 1001 for avoiding the cutting blade 7 is provided at the top of the base plate 1 at a position corresponding to the cutting blade 7; The drive cutting assembly 8 includes a U-shaped support plate 82 with its opening facing downwards, located on the top of the base plate 1. A lifting electric push rod 81 connected to the cutting blade 7 is located on the top of the U-shaped support plate 82. This design drives the cutting blade 7 to move vertically through the operation of the lifting electric push rod 81 in the drive cutting assembly 8. The clearance groove 1001 avoids the cutting blade 7, thus completing the cutting operation of the waterstop.

[0019] Reference Figure 1 An adjustment component 6 for driving the rotating column 4 to move vertically is provided on the upright plate 3; The adjusting assembly 6 includes an adjusting groove 62 formed on the side wall of the upright plate 3. An adjusting plate 61, rotatably connected to the rotating column 4, is installed inside the adjusting groove 62. An adjusting electric push rod 63, connected to the adjusting plate 61, is installed on the top of the upright plate 3. This design uses the adjusting electric push rod 63 in the adjusting assembly 6 to move the adjusting plate 61 vertically. The movement of the adjusting plate 61 moves the rotating column 4 vertically, which in turn moves the limiting ring 5 vertically to contact the upper surface of the waterstop, pressing the waterstop against the conveyor belt 2 for easy transport. The paired limiting rings 5 ​​also guide and limit the opposing side walls of the waterstop's protrusions, preventing tilting. Bearings are installed at the connection between the upright plate 3 and the rotating column 4, allowing the adjusting plates 61 at both ends of the rotating column 4 to move synchronously vertically.

[0020] Reference Figures 1-5 As an embodiment of this utility model: when it is necessary to cut the waterstop, by applying force to the limiting ring 5, the extension block 51 on the limiting ring 5 moves along the limiting groove 41, and at the same time, the limiting ring 5 slides along the side wall of the rotating column 4 to adjust the position of the limiting ring 5. When the gap between the paired limiting rings 5 ​​is in contact with the two side walls opposite the protrusions on the waterstop, the limiting adjustment of the waterstop is completed. By applying force to the locking member 9, the locking member 9 is in contact with the stop groove 42 to stop the extension block 51, thereby stopping the limiting ring 5 after the position is adjusted, preventing the limiting ring 5 from sliding, and completing the limiting and guiding adjustment of the waterstop.

[0021] After adjustment, the electric push rod 63 in the adjustment assembly 6 drives the adjustment plate 61 to move vertically. The movement of the adjustment plate 61 drives the rotating column 4 to move vertically. The movement of the rotating column 4 drives the limiting ring 5 to move vertically and contact the upper end face of the waterstop, pressing the waterstop in conjunction with the conveyor belt 2. This facilitates the conveying operation of the waterstop. Under the action of the paired limiting rings 5, the opposite side walls of the protrusions on the waterstop are limited and guided, preventing the waterstop from tilting. The anti-tilting effect is good, improving the subsequent cutting quality.

[0022] Finally, the lifting electric push rod 81 in the driving cutting assembly 8 drives the cutting blade 7 to move vertically, and the clearance groove 1001 avoids the cutting blade 7, thus completing the cutting operation of the waterstop. Under the action of the limiting rings 5 ​​on the rotating columns 4 on both sides of the cutting blade 7, the waterstop is pressed, improving the stability of the cut and enhancing the practicality of this utility model.
