Description

Technical Field

[0001] This utility model relates to the field of plastic pipe production technology, and in particular to a meter counter for pipe production. Background Technology

[0002] A measuring device measures the length of pipe that rolls around it. It consists of a measuring wheel, a graduated disc, a photoelectric encoder, and a digital processing unit. The measuring wheel is rotated by a cable pulled manually or by machine. The rotation angle of the graduated disc, coaxial with the measuring wheel, is detected by the photoelectric encoder. The signal processor converts the signal, automatically measuring the cable length based on the rotation angle of the graduated disc, and displays the accurate value on a screen. Currently, pipe factories typically use measuring devices mounted on one side of the pipe discharge machine using a folding rod. Operators manually remove the device during use and manually retract it when not in use, which is inconvenient. Furthermore, these measuring devices generally use ratchet-like mechanisms without gears, and slippage often occurs when using this traditional single-sided measuring device, leading to inaccurate length measurements.

[0003] In the prior art, utility model patent application number CN202120327493.5 discloses a pipe measuring device for pipe production, including a pipe feeding machine, a feeding machine support column, and a pipe measuring device. The pipe feeding machine is installed on the feeding machine support column, and the pipe measuring device is installed at the discharge port of the pipe feeding machine. The pipe measuring device includes a lifting positioning plate, a lifting cylinder, an L-shaped support plate, a rotating shaft, a rotating ratchet, and an encoder. The lifting positioning plate is located at the bottom of the feeding machine support column, and the lifting cylinder is vertically installed on the lifting positioning plate. An L-shaped support plate is fixedly connected to the output shaft of the lifting cylinder. The device features a support plate that automatically controls the movement of the meter counter, saving manual operation. Anti-slip teeth prevent ratchet slippage, improving meter counting accuracy. While this technology solves the aforementioned problems, in actual use, the lifting cylinder needs to support the entire meter counter, resulting in high operating pressure and making precise control difficult. When supporting the plastic pipe, excessive lifting force may cause deformation of the plastic pipe. Furthermore, while the anti-slip teeth prevent ratchet slippage in the rolling direction, they cannot prevent the plastic pipe from swaying and deviating, affecting the measurement. Therefore, this device is only suitable for rigid pipes and has room for further improvement. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a meter counter for pipe production, which solves the above-mentioned problem by taking into account the characteristics of plastic pipes.

[0005] To achieve the above objectives, a meter counter for pipe production is provided, comprising a fixed base, with lifting slide rods fixedly connected to both ends of the fixed base, a fixed top seat fixedly connected to the top of the two lifting slide rods, a meter counter body slidably connected to the two lifting slide rods below the fixed top seat, a fixed shaft fixedly connected to the middle of one side of the meter counter body, a measuring wheel rotatably connected to the end of the fixed shaft away from the meter counter body, an adjusting screw rotatably connected to the middle of the fixed top seat, and a screw handwheel fixedly connected to the top of the adjusting screw passing through the fixed top seat;

[0006] A bottom lifting seat is slidably connected to the bottom of the two lifting slides. Sliding sleeves are fixedly connected to both ends of the bottom lifting seat. A lifting cylinder is fixedly connected to the upper end of the fixed base at the corresponding position in the middle of the bottom lifting seat. A top rod pulley is rotatably connected to the side of the bottom lifting seat near the fixed shaft at the position corresponding to the measuring wheel. The outer edge of the top rod pulley has an arc-shaped concave structure.

[0007] According to the aforementioned meter counter for pipe production, the bottom of the fixed base is fixedly connected to the ground.

[0008] According to the aforementioned pipe production meter, the meter body is provided with a lead screw nut, and the end of the adjusting lead screw away from the fixed top seat passes through the meter body and is threadedly connected to the lead screw nut.

[0009] According to the aforementioned meter counter for pipe production, one bottom end of the bottom lifting seat is fixedly connected to the output end of the lifting cylinder.

[0010] According to the aforementioned meter counter for pipe production, a silicone sleeve is fixedly fitted onto the inner recess of the outer edge of the top rod pulley.

[0011] According to the aforementioned meter counter for pipe production, a through hole is provided on the side of the bottom lifting seat away from the top rod pulley.

[0012] According to the aforementioned pipe production meter, the end of the adjusting screw away from the main body of the meter passes through a through hole and is rotatably connected to the top of the fixed base.

[0013] The above solution has at least one of the following beneficial effects:

[0014] 1. This utility model is equipped with a bottom lifting seat and a lifting cylinder. In conjunction with the top rod pulley, when the plastic pipe is discharged, the lifting cylinder drives the bottom lifting seat to rise, which in turn drives the top rod pulley to hold the plastic pipe in place. This works in conjunction with the metering wheel above to form a clamping effect, effectively increasing the friction between the plastic pipe and the metering wheel, facilitating the rolling detection of the metering wheel. The cylinder does not need to drive the entire meter counter, reducing operating pressure, facilitating precise control, and avoiding pipe deformation caused by excessive force, thus enhancing the practicality of the device.

[0015] 2. The top rod pulley of this utility model has an outer edge with an arc-shaped concave structure. When it is fixedly fitted with a silicone sleeve at the concave part, it can fit against the side walls on both sides below the plastic pipe when it is pressing against the plastic pipe, so as to prevent the plastic pipe from shaking and deviating to the side and affecting the measurement. The silicone sleeve can also provide anti-slip and cushioning functions, which enhances the practicality of the device.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the description of the textual part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model. However, they should not be construed as limiting the scope of protection of the present utility model. Since the detection structure of the meter counter is the prior art that has been disclosed, this embodiment will not be described in detail.

[0025] Reference Figure 1-4 This utility model provides a meter counter for pipe production, including a fixed base 1. The bottom of the fixed base 1 is fixedly connected to the ground. Lifting slide rods 2 are fixedly connected to both ends of the upper part of the fixed base 1. A fixed top seat 8 is fixedly connected to the top of the two lifting slide rods 2. A meter counter body 3 is slidably connected to the two lifting slide rods 2 below the fixed top seat 8. A fixed shaft 4 is fixedly connected to the middle of one side of the meter counter body 3. A measuring wheel 5 is rotatably connected to the end of the fixed shaft 4 away from the meter counter body 3. An adjusting screw 9 is rotatably connected to the middle of the fixed top seat 8. The top of the screw 9 passes through the fixed top seat 8 and is fixedly connected to the screw handwheel 10. The inside of the meter counter body 3 is provided with a screw nut. The end of the adjusting screw 9 away from the fixed top seat 8 passes through the meter counter body 3 and is threadedly connected to the screw nut. The middle part of the bottom lifting seat 6 is provided with a through hole on the side away from the top rod pulley 12. The end of the adjusting screw 9 away from the meter counter body 3 passes through the through hole and is rotatably connected to the top of the fixed base 1. The height of the meter counter body 3 can be adjusted by rotating the screw handwheel 10 according to the discharge position of the plastic pipe, which is convenient for measuring the plastic pipe.

[0026] A bottom lifting seat 6 is slidably connected below the two lifting slide rods 2. Sliding sleeves 7 are fixedly connected to both ends of the bottom lifting seat 6. A lifting cylinder 11 is fixedly connected to the upper end of the fixed base 1 at a position corresponding to the middle of the bottom lifting seat 6. The bottom end of the bottom lifting seat 6 is fixedly connected to the output end of the lifting cylinder 11. A top rod pulley 12 is rotatably connected to the side of the bottom lifting seat 6 near the fixed shaft 4 at a position corresponding to the metering wheel 5. When the plastic pipe discharges material, the bottom lifting seat 6 can be driven to rise by the lifting cylinder 11. This causes the top rod pulley 12 to press against the plastic pipe, forming a clamping effect with the measuring wheel 5 above. This effectively increases the friction between the plastic pipe and the measuring wheel 7, facilitating the rolling detection of the measuring wheel. The outer edge of the top rod pulley 12 has an arc-shaped concave structure, and a silicone sleeve is fixedly fitted to the concave part of the outer edge of the top rod pulley 12. When pressing against the plastic pipe, the concave outer edge fits against the side walls on both sides below the plastic pipe, preventing the plastic pipe from shaking or deviating and affecting the measurement. The silicone sleeve also provides lateral anti-slip and cushioning.

[0027] Working Principle: The bottom lifting seat 6 and lifting cylinder 11 of this utility model, together with the top rod pulley 12, can drive the bottom lifting seat 6 to rise when the plastic pipe is discharged, thereby driving the top rod pulley 12 to hold the plastic pipe. This, together with the measuring wheel 5 above, forms a clamping effect, effectively increasing the friction between the plastic pipe and the measuring wheel 7, facilitating the rolling detection of the measuring wheel. The cylinder does not need to drive the entire meter counter, reducing operating pressure and facilitating precise control. At the same time, the silicone sleeve can also buffer the plastic pipe, preventing the pipe from deforming due to excessive force. The outer edge of the arc-shaped concave structure of the top rod pulley 12, together with the silicone sleeve fixedly fitted in the concave part, can fit against the side walls on both sides below the plastic pipe when holding it, preventing the plastic pipe from shaking and deviating to the side, thus affecting the measurement. The silicone sleeve also provides lateral anti-slip and cushioning, enhancing the practicality of the device.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
