Description

Technical Field

[0001] This utility model belongs to the field of template cutting technology, specifically relating to a template cutting device for sewage treatment construction projects. Background Technology

[0002] During the construction of sewage treatment plants, a large number of building formworks are required. The cutting of building formworks is a crucial part of the construction process, and its accuracy directly affects the forming quality and construction efficiency of subsequent concrete pouring. In the current industry situation, most building formwork cutting is done by bench saws. Bench saws are widely used in construction sites and formwork processing workshops due to their high cutting efficiency.

[0003] Chinese patent application CN219359677U discloses an automatic sliding table saw for cutting wood. This automatic sliding table saw features adjustable limit clamping rails at both ends of the worktable. The position of the limit clamping rails is adjusted by an electric telescopic support at the rear end, facilitating the positioning and clamping of the wood to be cut. It can clamp wood of different sizes, making it more versatile. By setting multiple guide wheels inside the two limit clamping rails, the clamped wood can slide within the two limit clamping rails with limited movement. A limit pressure roller is detachably installed on the top of one limit clamping rail. The height of the limit pressure roller is adjusted by an electric telescopic rod, which can stably press wood of different thicknesses. Combined with the guiding effect of the guide wheels, the wood to be cut is less likely to shift during cutting, effectively improving the accuracy of wood processing.

[0004] However, when using this device, the sidewall of the board must first be fixed by adjusting the limiting clamping rail using an electric telescopic support, and then the height of the board is limited by an electric telescopic rod in conjunction with a limiting pressure roller. Although this dual limiting method can effectively prevent displacement of the board during processing and ensure cutting stability, the two-step process design makes the overall procedure more cumbersome. It not only increases the number of steps for operators but also extends the pre-processing time of a single board to some extent, thereby reducing the overall processing efficiency of the cutting device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a template cutting device for sewage treatment construction projects, which solves the problem of low pretreatment efficiency of existing template cutting devices for boards.

[0006] The technical solution adopted by this utility model is a template cutting device for sewage treatment construction engineering, including a cutting table, a motor fixedly connected to the bottom of the cutting table, a cutting blade fixedly connected to the motor shaft of the motor, the cutting blade being able to extend out of a strip hole provided on the top surface of the cutting table, a positioning mechanism provided on the top surface of the cutting table and the positioning mechanism being located on both sides of the strip hole, and a material pushing mechanism for pushing templates provided on the cutting table; The positioning mechanism includes a slide table, which is slidably connected to the cutting table and its sliding direction is perpendicular to the cutting direction of the cutting blade. Two sliding plates perpendicular to the slide table are slidably connected to the slide table and are arranged symmetrically to the left and right of the cutting blade. Multiple rotating shafts are rotatably connected to the sliding plates along their length and extend out of the bottom surface of the sliding plates. The bottom end of each rotating shaft is rotatably connected to a limit roller. A protruding plate is fixedly connected to the bottom of the slide table after passing through the top plate of the cutting table. An electric telescopic rod is fixedly connected to the side wall inside the cutting table. The output end of the electric telescopic rod is fixedly connected to the protruding plate and can drive the slide table to slide back and forth.

[0007] Furthermore, the aforementioned slide plate is provided with a receiving groove along its length direction, and a bidirectional threaded rod is rotatably connected in the receiving groove along its length direction. The two slide plates are respectively helically connected to the two oppositely rotating threaded parts of the bidirectional threaded rod by two threaded sleeves provided at their ends. A knob is fixedly connected to one end of the bidirectional threaded rod after it extends out of the side wall of the receiving groove.

[0008] Furthermore, the aforementioned pushing mechanism includes a slider, which is slidably connected to a sliding strip hole provided on the top plate of the cutting table. The sliding strip hole extends from back to front next to the cutting blade. A push rod is fixedly connected to the top of the slider and the push rod is higher than the top plate of the cutting table. A handle is fixedly connected to the bottom of the slider, which extends forward out of the front end of the cutting table.

[0009] Furthermore, the aforementioned sliders and push rods are provided in two sets, with the two sets of sliders and push rods being symmetrical about the cutting blade.

[0010] Furthermore, the diameter of the aforementioned limiting roller gradually decreases from top to bottom, forming an inverted cone shape.

[0011] Furthermore, a rubber sleeve is fixedly connected to the outer wall of the aforementioned limiting roller.

[0012] This utility model has the following beneficial effects: 1) By setting the limiting roller, this utility model can not only limit and clamp the left and right sides of the plate to prevent the plate from shifting during the cutting process, but also limit the height of the plate to prevent the plate from bouncing up. This can fully fix the plate. Moreover, only two sets of sliding plates need to be close to each other to achieve clamping and height restriction of the plate. There are fewer operation steps, making it more convenient to use and greatly improving the efficiency of plate cutting. 2) Through the design of the material pushing mechanism, this utility model allows the material to be automatically moved close to the cutting blade to complete the cutting without the need for the worker to come into contact with the material and the cutting blade. This avoids the worker from coming close to the high-speed cutting blade and thus effectively reduces safety hazards. Attached Figure Description

[0015] The present invention will be further explained below with reference to the accompanying drawings to enable those skilled in the art to better understand it.

[0016] Example 1, such as Figure 1 - Figure 4 As shown, a template cutting device for sewage treatment construction projects includes a cutting table 1. A motor 2 is fixedly connected to the bottom of the cutting table 1. A cutting blade 4 is fixedly connected to the motor shaft 3 of the motor 2. The cutting blade 4 can extend out of the strip hole 101 provided on the top surface of the cutting table 1. A positioning mechanism 5 is provided on the top surface of the cutting table 1 and the positioning mechanism 5 is located on both sides of the strip hole 101. The positioning mechanism prevents the board from shifting left and right during the cutting process. A pushing mechanism 6 for pushing templates is provided on the cutting table 1. The positioning mechanism 5 includes a slide table 51, which is slidably connected to the cutting table 1 and its sliding direction is perpendicular to the cutting direction of the cutting blade 4. Two sliding plates 52 are slidably connected to the slide table 51 and are perpendicular to it. The two sliding plates 52 are symmetrically arranged to the left and right of the cutting blade 4. Multiple rotating shafts 53 are rotatably connected to the sliding plates 52 along their length and extend out of the bottom surface of the sliding plates 52. The bottom end of the rotating shafts 53 is rotatably connected to a limiting roller 54. The limiting roller 54 can clamp the two sides of the board. The bottom of the slide table 51 passes through the top plate of the cutting table 1 and is fixedly connected to a protruding plate 57 to prevent the board from shifting left and right during the cutting process. An electric telescopic rod 58 is fixedly connected to the side wall inside the cutting table 1. The output end of the electric telescopic rod 58 is fixedly connected to the protruding plate 57 and can drive the slide table 51 to slide back and forth. Specifically, the diameter of the limiting roller 54 gradually decreases from top to bottom, forming an inverted cone shape. This allows for self-positioning and centering adjustment of the template, as well as horizontal and vertical limiting. Because the diameter of the limiting roller 54 gradually decreases from top to bottom, it restricts the height of the template after clamping it at the side, preventing it from springing upwards. A rubber sleeve 510 is fixedly connected to the outer wall of the limiting roller 54. The rubber sleeve 510 increases the friction between the limiting roller 54 and the template, thereby improving the clamping effect of the limiting roller 54.

[0017] Specifically, the slide plate 52 is provided with a receiving groove 511 along its length direction. A bidirectional threaded rod 55 is rotatably connected in the length direction within the receiving groove 511. The two slide plates 52 are respectively spirally connected to the two oppositely rotating threaded parts of the bidirectional threaded rod 55 by two threaded sleeves 59 provided at their ends. A knob 56 is fixedly connected to one end of the bidirectional threaded rod 55 after it extends out of the side wall of the receiving groove. By rotating the bidirectional threaded rod 55 through the knob 56, the two sets of threaded sleeves 59 connected to it can drive the two sets of slide plates 52 to slide synchronously in opposite directions on the inner wall of the slide table 51.

[0018] The specific connection structure between the slide plate 52 and the slide table 51 is as follows: a slider 5201 is provided at the end of the slide plate 52. The slider 5201 is an inverted T-shape. Two symmetrical horizontal slide grooves 5111 are provided along the length of the receiving slide groove 511 near the top side walls. The inverted T-shaped slider 5201 is embedded in the two horizontal slide grooves 5111 to form a sliding part. The slider 5201 moves along the length of the horizontal slide groove 5111. A baffle is fixedly connected to one end of the receiving slide groove 511 by screws. When installing the slide plate, the baffle is removed, the slider 5201 is connected to the horizontal slide groove 5111, and then the baffle is fixedly connected. A threaded sleeve 59 is fixedly connected to the bottom of the slider 5201. Under the drive of the bidirectional threaded rod 55, the slider 5201 can be driven to move in a straight line.

[0019] The material pushing mechanism 6 includes a slider 61, which is slidably connected to a sliding strip hole 64 on the top plate of the cutting table 1. The sliding strip hole 64 extends from back to front beside the cutting blade 4. A push rod 62 is fixedly connected to the top of the slider 61, and the push rod 62 is higher than the top plate of the cutting table 1. A handle 63 is fixedly connected to the bottom of the slider 61, extending forward out of the front end of the cutting table 1. As the slider 61 slides, it drives the push rod 62 to move synchronously. As the push rod 62 moves, it pushes the board placed on the cutting table 1, so that the board moves smoothly under the guidance of the limiting roller 54. Pulling the handle 63 allows the slider 61 to slide on the inner wall of the cutting table 1. To ensure balanced pushing and pulling forces, two sets of sliders 61 and push rods 62 are provided, and the two sets of sliders 61 and push rods 62 are symmetrical about the cutting blade 4.

[0020] The top of the slider 61 is provided with a T-shaped part 6101. The sliding strip hole 64 is provided with two symmetrical horizontal sliding grooves 6401 along its length direction near the top two side walls. The two horizontal sliding grooves 6401 are embedded in the T-shaped part 6101 to form a sliding part. The T-shaped part 6101 moves along the length direction of the horizontal sliding groove 6401. The front end of the sliding strip hole 64 is provided with a through groove (not shown) for embedding the slider 61. The length and width of the through groove are both greater than the length and width of the slider, which facilitates the slider to be snapped in and the inverted T-shaped part 6101 to be embedded in the horizontal sliding groove 6401. A detachable T-shaped block (not shown) is embedded in the through groove to fill the through groove and limit the slider, preventing the slider from slipping in the through groove.

[0021] Working principle: Place the board to be cut on the back side of the cutting table 1 (located behind the cutting blade) and between the two sets of sliding plates 52. Then, rotate the bidirectional threaded rod 55 by the knob 56. As the bidirectional threaded rod 55 rotates, the two sets of threaded sleeves 59 connected to it can drive the two sets of sliding plates 52 to slide synchronously on the inner wall of the slide table 51 and move closer to each other. At the same time, the sliding plates 52 will drive the rotating shaft 53 to move synchronously, so that the rotating shaft 53 drives the limiting roller 54 to move synchronously until the rubber sleeve 510 on the outer wall of the limiting roller 54 is in close contact with the side wall of the board. At this time, the limiting roller 54 can clamp the two sides of the board to prevent the board from shifting during the cutting process. Since the diameter of the limiting roller 54 gradually decreases from top to bottom, the limiting roller 54 will limit the height of the board after clamping the side wall of the board, so that the board cannot bounce upward. The limiting roller 54 can clamp the board and limit its height, and the board can be cut at this time.

[0022] When the limiting rollers 54 under the two sets of slide plates 52 clamp the left and right sides of the board, the electric telescopic rod 58, together with the convex plate 57, can drive the slide table 51 to slide on the inner wall of the cutting table 1. While the slide table 51 is sliding, it will drive the slide plate 52 to move synchronously. At this time, the limiting rollers 54 under the slide plate 52 can be used to drive the board to move laterally above the cutting table 1, so as to adjust the distance between the side of the board and the cutting blade 4, so as to flexibly cut the size of the board according to the requirements.

[0023] When the limiting rollers 54 under the two sets of sliding plates 52 clamp the left and right sides of the board, the starting motor 2 drives the motor shaft 3 to rotate, which in turn drives the cutting blade 4 to rotate at high speed. At this time, the handle 63 is pulled, which causes the slider 61 to slide on the cutting table 1 and gradually approach the cutting blade 4. The slider 61 will drive the push rod 62 to move synchronously. As the push rod 62 moves, it will push the board placed on the cutting table 1, so that the board gradually approaches the high-speed rotating cutting blade 4 under the clamping of the limiting rollers 54, thereby cutting the board. The board can be cut without the operator having to touch it.
