Description

Technical Field

[0001] This utility model relates to the field of plastic profile verticality measurement, specifically an adjustable plastic profile extrusion verticality measuring device. Background Technology

[0002] The plastic profile perpendicularity measuring device is a specialized device used to detect whether the adjacent surfaces of a plastic profile maintain the perpendicular relationship required by the design during the extrusion molding process. The device obtains the spatial position or angle information of key parts of the profile through contact or non-contact sensing methods, and judges its perpendicularity deviation accordingly, thereby realizing real-time monitoring and control of product quality.

[0003] When testing the verticality of irregularly shaped plastic profiles with an inclined bottom or non-horizontal installation, traditional methods usually rely on custom-made positioning fixtures to rigidly fix the profiles and then read the verticality deviation data through probes. The special positioning fixtures are designed for a single cross-sectional specification, and their positioning reference, support profile and clamping structure are completely matched with the specific profile. Once the product model is changed, the positioning fixtures need to be changed. When testing multiple varieties and small batches of profiles, frequent fixture changes can easily introduce installation errors and affect measurement repeatability. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, when testing the verticality of irregularly shaped plastic profiles with an inclined bottom or non-horizontal installation, traditional methods typically rely on custom-made positioning fixtures to rigidly fix the profiles and then read the verticality deviation data using probes. These dedicated positioning fixtures are designed for a single cross-sectional specification, and their positioning reference, support profile, and clamping structure are all perfectly matched to the specific profile. Once the product model is changed, the positioning fixture needs to be replaced. When testing multiple varieties and small batches of profiles, frequent fixture replacements can easily introduce installation errors and affect the repeatability of measurements. This utility model proposes an adjustable verticality measuring device for extrusion production of plastic profiles.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an adjustable verticality measuring device for extrusion of plastic profiles, including a verticality measuring device body, wherein an adaptive mechanism is provided on the top of the verticality measuring device body.

[0006] The adaptive mechanism includes an airbag disposed on the top of the verticality measuring device body. An air pump is fixedly connected to the inner wall of the verticality measuring device body. A connecting pipe is fixedly connected to the air pump's air extraction end. An air extraction pipe is provided at one end of the connecting pipe. A diverter pipe is fixedly connected to the surface of the air extraction pipe. There are six diverter pipes. One end of each of the six diverter pipes penetrates into the inner wall of the airbag. A filter screen is fixedly connected to one end of each of the six diverter pipes. Glass beads are provided on the inner wall of the airbag. Grooves are formed on the surface of the airbag.

[0007] Preferably, a partition is fixedly connected to the inner wall of the verticality measuring device body, and a rotating rod is rotatably connected to the top of the partition. One end of the rotating rod passes through the inner wall of the verticality measuring device body and extends to the outside. A turntable is fixedly connected to the top of the rotating rod, and the bottom of the airbag is fixedly connected to the top of the turntable. The airbag is rotatably connected to the top of the verticality measuring device body through the turntable.

[0008] Preferably, the suction pipe is fixedly connected to the inner wall of the rotating rod, the other end of each of the six diversion pipes passes through the inner wall of the rotating rod, one end of the suction pipe passes through the inner wall of the partition, and a check valve is fixedly connected to the inner wall of each of the six diversion pipes.

[0009] Preferably, a motor is fixedly connected to the inner wall of the verticality measuring device body, and a transmission disc is fixedly connected to the output end of the motor.

[0010] Preferably, a transmission wheel is fixedly connected to the surface of the transmission disc, and an intermittent wheel is fixedly connected to the surface of the rotating rod, with the surface of the transmission disc in contact with the surface of the intermittent wheel.

[0011] Preferably, the surface of the intermittent wheel is provided with four U-shaped grooves, and the surface of the transmission wheel contacts the inner wall of the four U-shaped grooves.

[0012] Preferably, one end of the suction pipe is fixedly connected to a rotary joint, and the other end of the rotary joint is fixedly connected to one end of the connecting pipe. The suction pipe and the connecting pipe are rotatably connected through the rotary joint.

[0013] The advantages of this utility model are:

[0014] This invention utilizes an adaptive mechanism to place the plastic profile within an open groove at the top of a flexible airbag. Upon activation of the air pump, negative pressure is used to evenly extract air from the gaps between the glass beads within the airbag via a connecting pipe, an extraction pipe, and a distribution pipe. This causes the glass beads to be tightly locked under atmospheric pressure, transforming the flexible state into a near-rigid support state. The mechanism adaptively wraps around and firmly fixes any contour at the bottom of the profile, eliminating the need to change specialized tooling and shortening downtime during product changeovers. Because the glass beads are encased within the flexible airbag, their clamping force is buffered by the airbag and evenly distributed across the profile surface, preventing indentations, scratches, or gloss damage caused by rigid contact. This ensures stable clamping while enabling non-destructive testing. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses an adjustable verticality measuring device for extrusion of plastic profiles. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An adjustable verticality measuring device for extrusion of plastic profiles includes a verticality measuring device body 1, and an adaptive mechanism 2 is provided on the top of the verticality measuring device body 1.

[0025] The adaptive mechanism 2 includes an airbag 201, which is located on the top of the verticality measuring device body 1. An air pump 202 is fixedly connected to the inner wall of the verticality measuring device body 1. A connecting pipe 203 is fixedly connected to the air pump 202's suction end. An air suction pipe 204 is provided at one end of the connecting pipe 203. Six diverter pipes 205 are fixedly connected to the surface of the air suction pipe 204. One end of each of the six diverter pipes 205 penetrates into the inner wall of the airbag 201, and a filter screen 206 is fixedly connected to one end of each of the six diverter pipes 205. Glass beads 207 are provided on the inner wall of the airbag 201, and grooves 208 are formed on the surface of the airbag 201. By setting the adaptive mechanism 2, the plastic profile is placed... Within the open groove 208 at the top of the flexible airbag 201, after the air pump 202 is started, negative pressure is evenly extracted from the gaps between the glass beads 207 inside the airbag 201 through the connecting pipe 203, the air extraction pipe 204, and the diversion pipe 205. This causes the glass beads 207 to be tightly locked under atmospheric pressure, changing from a flexible state to a near-rigid support state. This adaptively wraps around and firmly fixes any contour of the bottom of the profile, eliminating the need to change special tooling and shortening the downtime preparation time when changing product models. Since the glass beads 207 are wrapped inside the flexible airbag 201, their clamping force is buffered by the airbag 201 and evenly distributed on the surface of the profile, avoiding indentations, scratches, or gloss damage caused by rigid contact. This ensures stable clamping while achieving non-destructive testing.

[0026] Reference Figure 2A partition 4 is fixedly connected to the inner wall of the verticality measuring device body 1. A rotating rod 8 is rotatably connected to the top of the partition 4. One end of the rotating rod 8 passes through the inner wall of the verticality measuring device body 1 and extends to the outside. A turntable 3 is fixedly connected to the top of the rotating rod 8. The bottom of the airbag 201 is fixedly connected to the top of the turntable 3. The airbag 201 is rotatably connected to the top of the verticality measuring device body 1 through the turntable 3. Through the setting of the partition 4, the rotating rod 8 and the turntable 3, the partition 4 provides a stable central support for the rotating rod 8, ensuring that the rotating rod 8 remains stable and smooth during rotation. The rotating rod 8 drives the turntable 3 to rotate synchronously, thereby causing the airbag 201 fixed to the top of the turntable 3 to rotate accordingly, which can detect different surfaces of the profile.

[0027] Reference Figure 2 and Figure 5 The suction pipe 204 is fixedly connected to the inner wall of the rotating rod 8. The other ends of the six diversion pipes 205 all penetrate into the inner wall of the rotating rod 8. One end of the suction pipe 204 penetrates into the inner wall of the partition 4. Check valves 9 are fixedly connected to the inner walls of the six diversion pipes 205. Through the setting of the suction pipe 204 and the check valves 9, the rotation of the rotating rod 8 drives the suction pipe 204 and the diversion pipes 205 to rotate synchronously, avoiding the diversion pipes 205 from twisting, bending or tangling during rotation, ensuring the smooth flow of the vacuum path. The check valves 9 can automatically close after the suction pump 202 stops working, preventing the negative pressure in the air bag 201 from leaking, maintaining the stable clamping state of the profile during the measurement process, and ensuring the continuity and stability of the vacuuming process.

[0028] Reference Figure 2 and Figure 5 A motor 6 is fixedly connected to the inner wall of the verticality measuring device body 1. A transmission disk 7 is fixedly connected to the output end of the motor 6. Through the setting of the motor 6 and the transmission disk 7, the motor 6 provides driving force to drive the transmission disk 7 to rotate, thereby driving the turntable 3 and the airbag 201 above to rotate, so that the fixed plastic profile rotates smoothly, which makes it convenient for the probe of the verticality measuring device body 1 to perform verticality detection on different surfaces of the profile.

[0029] Reference Figure 5 A transmission wheel 10 is fixedly connected to the surface of the transmission disk 7, and an intermittent wheel 12 is fixedly connected to the surface of the rotating rod 8. The surface of the transmission disk 7 is in contact with the surface of the intermittent wheel 12. Through the setting of the transmission wheel 10 and the intermittent wheel 12, when the motor 6 drives the transmission disk 7 to rotate, the transmission wheel 10 rotates accordingly and periodically pushes the intermittent wheel 12, so that the intermittent wheel 12 drives the rotating rod 8 to achieve intermittent rotation, thereby controlling the turntable 3 and the upper airbag 201 to rotate step by step at a set angle. Each rotation stops at a preset position to ensure that the probe is aligned with the target measurement surface and to ensure the accuracy of the verticality detection.

[0030] Reference Figure 5The surface of the intermittent wheel 12 is provided with U-shaped grooves 11, and there are four U-shaped grooves 11. The surface of the transmission wheel 10 contacts the inner wall of the four U-shaped grooves 11. Through the setting of the U-shaped grooves 11, when the transmission disc 7 drives the transmission wheel 10 to rotate continuously, the transmission wheel 10 periodically embeds into the inner wall of the U-shaped groove 11 and pushes the side wall of the U-shaped groove 11, driving the intermittent wheel 12 to achieve rotation at four equal angles, which facilitates automatic detection of plastic profiles with multiple faces.

[0031] Reference Figure 2 and Figure 4 One end of the suction pipe 204 is fixedly connected to a rotary joint 5, and the other end of the rotary joint 5 is fixedly connected to one end of the connecting pipe 203. The suction pipe 204 and the connecting pipe 203 are rotatably connected through the rotary joint 5. With the setting of the rotary joint 5, when the rotating rod 8 drives the suction pipe 204 to rotate, the rotary joint 5 ensures that the vacuum pipeline remains sealed and connected in the rotating state, avoiding twisting, bending or entanglement caused by the rotation of the suction pipe 204, and ensuring stable transmission of negative pressure.

[0032] Working principle: The perpendicularity measuring device fixes the plastic profile on the platform. The probe assembly is connected to the electric push rod. The PLC or control system automatically sets the target height according to the profile model, driving the probe to move up and down. The probe head contacts the surface of the plastic part to obtain its spatial position or normal angle information. The perpendicularity is then calculated geometrically and displayed in real time on the screen. This is existing technology and will not be elaborated further. After the plastic profile to be tested is cooled and shaped from the extruder head, it is placed in the open groove 208 of the flexible airbag 201 at the top of the perpendicularity measuring device body 1. The airbag 201 is filled with a large number of glass beads 207. The bottom of the airbag 201 is fixedly connected to the turntable 3. During the clamping process, the user starts the vacuum pump 202 through an external control switch. The vacuum pump 202 is powered by an external power supply and generates negative pressure. The vacuum end is transmitted to the vacuum tube 204 through the connecting pipe 203 and the rotary joint 5. The vacuum tube 204 then evenly guides the air into the airbag 201 through the diverter pipe 205, extracting the air from the gaps between the glass beads 207. A filter screen 206 is installed in the diverter pipe 205 to facilitate the vacuuming process. The airbag 201 intercepts the glass beads 207 inside, preventing them from being drawn into the diversion pipe 205 due to negative pressure adsorption or airflow disturbance, thus avoiding pipe blockage. As the air pressure inside the airbag 201 decreases, the external atmospheric pressure causes the glass beads 207 to pack tightly and lock together, transforming them from a flexible state into a near-rigid support. This adaptively wraps around the bottom contour of the profile, achieving non-destructive, stable, and close-fitting fixation regardless of whether it is a flat, inclined, curved, or multi-cavity irregular structure. Simultaneously, the suction pipe 204 is equipped with a check valve 9, which automatically closes after the vacuum pump stops, maintaining negative pressure inside the airbag 201. The pressure is used to prevent the profile from loosening during the measurement process. After the probe has finished testing one side, the user starts the motor 6 through an external control switch. The motor 6 is powered by an external power supply. The output end of the motor 6 drives the transmission disk 7 to rotate. The transmission wheel 10 is connected to the surface of the transmission disk 7. As the transmission disk 7 rotates, the transmission wheel 10 enters the U-shaped groove 11 of the intermittent wheel 12 and pushes the side wall of the U-shaped groove 11, driving the intermittent wheel 12 and the rotating rod 8 to achieve intermittent rotation of 90 degrees. This drives the turntable 3 and the airbag 201, together with the profile, to switch to four preset detection positions to measure the perpendicularity of different surfaces.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
