Description

Technical Field

[0001] This invention relates to the field of plastic pipe processing technology, and in particular to a high-frequency hot melt tip forming machine for plastic pipes and its control method. Background Technology

[0002] When manufacturing and processing plastic pipes, it is necessary to heat-melt both ends of the plastic pipe to seal it, so that the plastic pipe can be adapted to specific use scenarios and meet the functional, safe connection or performance requirements of different scenarios.

[0003] In the existing technology, the production process of heat-sealing plastic pipes is mainly carried out by workers based on their processing experience. Usually, workers soften the plastic pipes with a hot air gun or heating wire, and then press the plastic pipes into a specific mold to achieve sealing.

[0004] Because workers cannot accurately know the melting range of the plastic tube during heating and sealing, and it is difficult to judge the degree of pressing when pressing the plastic tube into the mold after melting, the softening of the plastic tube head will vary due to different temperatures, and the sealing consistency of the same model of plastic tube will vary due to different degrees of pressing. High-precision production cannot be achieved, and there is still room for improvement. Summary of the Invention

[0005] To improve the production precision of plastic pipes, this invention provides a high-frequency hot melt tip forming machine for plastic pipes and its control method.

[0018] A fixed component, set on the pushing component, is used to restrict the movement of the pushing component;

[0019] A reset component, mounted on the housing, is used to release the fixing component and restore the pushing component to its original position after the pushing component has been pushed.

[0020] The housing has a groove for sliding the handle.

[0021] By adopting the above technical solution, a hot melt assembly is set inside the shell and the head of the plastic tube is changed by the deformation assembly. Then, a moving mechanism is used to move the plastic tube toward the hot melt assembly, thereby completing the hot melt sealing process of the end of the plastic tube.

[0022] Optionally, the pushing component includes:

[0026] A return spring is located on the side of the push rod away from the abutment block, used to return the push rod to its original position;

[0027] The movable disk has a push groove for the push block to slide and be limited.

[0028] By adopting the above technical solution, the push handle is installed on the push rod. By sliding the push handle, the push rod is moved, which in turn moves the moving disk. Then, by turning the moving handle, the moving disk is moved, which in turn moves the plastic tube.

[0029] Optionally, the fixing component includes:

[0030] The mounting base is located inside the housing;

[0031] A snap-fit ​​block, mounted on a fixed base, is used to fix the push rod after it has been pushed.

[0044] By adopting the above technical solution, a reset motor is installed inside the housing, and a reset gear is installed on the reset motor. After the abutment block abuts against the reset button, the reset motor is controlled to rotate. After the reset motor rotates, the reset block on the reset gear hits the return rod. Thus, after the plastic tube is processed, the reset motor hits the return rod, causing the fixed contact on the push rod to bring the plastic tube out of the processing area.

[0051] The telescopic fixed plate has a sliding groove for the telescopic rod of the telescopic electric cylinder to slide, and the movable plate has a movable groove for the telescopic fixed plate to rotate and connect.

[0052] By adopting the above technical solution, a clamping pedal is set on the ground. The clamping pedal drives the telescopic electric cylinder to extend and retract. After extension and retraction, the rotating gear rotates, thereby driving the clamping bracket to move to fix the plastic tube.

[0053] Optionally, the hot melt assembly includes:

[0059] The deformation component includes:

[0060] Deformation element, located on the side of the hot melt wire away from the insertion frame, is used to compress and deform the plastic tube after hot melting;

[0061] The air inlet pipe is located on the side of the hot melt base near the hot melt wire, and is used to bring in gas to cool the plastic tube after compression;

[0062] An intake connector is located between the intake pipe and the heat fusion base, and is used for connecting the intake pipe;

[0063] The hot melt base has an insertion slot for inserting the insertion frame, the insertion frame has an insertion hole for inserting the plastic tube, and the hot melt base has a threaded groove for threading the deformable part.

[0064] By adopting the above technical solution, a hot melt base is provided on the shell, and an insertion frame and an insertion plate are installed inside the hot melt base. The insertion plate is fixed to the hot melt base by fixing bolts, and the insertion frame is fixed. A deformation component and an air inlet pipe are provided on the hot melt base, thereby realizing the heating of the plastic tube and the cooling of the plastic tube by controlling the air inlet pipe, so as to realize the melting, sealing and cooling of the plastic tube.

[0065] Secondly, this application provides a method for controlling the high-frequency hot-melt tip forming of a plastic tube, employing the following technical solution:

[0066] A method for controlling the high-frequency hot-melt tip forming of a plastic pipe includes:

[0067] When the reset button is pressed, a push command is issued. In response to the push command, the clamping distance after the plastic tube is clamped is obtained.

[0068] The outer diameter of the plastic tube and the melting temperature of the hot melt wire are determined based on the clamping distance.

[0069] The deformation distance is calculated based on the outer diameter of the plastic pipe, and the softening rate is matched according to the outer diameter of the plastic pipe and the melting temperature.

[0070] The movement distance is determined by matching the softening speed and deformation distance.

[0071] Based on the moving distance, the plastic tube is driven to move towards the deformable part with a preset moving power until the deformation distance is reached and then the movement stops.

[0072] By adopting the above technical solution, after the plastic tube is inserted into the hot melt assembly, the outer diameter and melting temperature of the plastic tube are obtained to melt the plastic tube. The moving distance of the plastic tube is matched based on the deformation distance and softening speed, and the movement of the plastic tube is controlled. In this way, the plastic tube is pushed forward during the softening process, thereby realizing the processing of the plastic tube.

[0073] Optional, also includes:

[0074] The current moving speed of the plastic tube as it moves toward the deformed part and the clamping weight of the plastic tube when the clamping mechanism clamps it are collected.

[0075] A reference moving speed is determined by matching the moving power, the outer diameter of the plastic tube, and the clamping weight.

[0076] Record the movement time point when the current movement speed is the same as the baseline movement speed;

[0077] The additional distance at each movement time point is determined by matching the outer diameter of the plastic tube with the overall movement time point.

[0078] The final distance is calculated based on the additional distance and the distance traveled;

[0079] In response to the final distance control, the moving motor drives the plastic tube to move towards the deformable part until the final distance is reached and then stops moving.

[0080] By adopting the above technical solution, after obtaining the current moving speed, the corresponding reference moving speed of the plastic tube is matched, and the moving time point when the current moving speed is the same as the reference moving speed is recorded, the moving distance is determined, the final distance is calculated, and the plastic tube is controlled to move according to the final distance, so that when the end of the plastic tube is beveled, the plastic tube is softened and sealed more evenly.

[0081] Optional, also includes:

[0082] Get the current temperature and the time it takes for the temperature to rise;

[0083] The degree of melting of the outer diameter of the plastic tube is determined based on the outer diameter of the plastic tube, the current temperature, and the temperature rise time.

[0084] The rotation speed is matched based on the degree of melting;

[0085] The motor power is determined based on the rotation speed, and the current power is obtained;

[0086] The compensation power is determined by comparing the motor power with the current power.

[0087] The compensation speed is matched based on the compensation power;

[0088] The rotation mode is matched based on whether the speed compensates for the difference between the speed and the preset reference speed range. The rotation modes include intermittent rotation and load rotation.

[0089] When the compensation speed falls within the preset reference speed range, the rotation mode is intermittent rotation. The intermittent rotation value is determined based on the compensation speed, and the rotator is controlled to rotate the plastic tube based on the intermittent rotation value.

[0090] When the compensation speed does not fall within the preset reference speed range, the rotation mode is load rotation, and the plastic tube is rotated according to the compensation power and rotation speed.

[0091] By adopting the above technical solution, when the plastic tube moves, the degree of melting of the plastic tube is obtained and the rotation speed is matched. The current power of the rotating motor is obtained, and the compensation power is determined based on the current power and the compensation rotation is matched. Thus, when the plastic tube moves while melting, the smoothness of the melting and shaping of the plastic tube is improved by rotating, and the distribution is more even on the end of the plastic tube.

[0092] Optional, also includes:

[0093] The support point is determined by matching the outer diameter of the plastic tube with the clamping weight when the plastic tube rotates.

[0094] Determine the length of the line segment based on the outer diameter of the plastic pipe;

[0095] Based on the line segment length and support point control line segment, the plastic pipe is hoisted and supported, and after support, the alignment beam is emitted.

[0096] Acquire alignment images of the aligned beam and identify the beam position based on the alignment images;

[0097] The offset distance and offset direction are determined based on the beam position and the preset reference position;

[0098] The length of the line segment is changed based on the offset direction and offset distance until the beam position coincides with the reference position.

[0099] By adopting the above technical solution, when the plastic tube rotates, the support point is matched and supported by hoisting. After support, the plastic tube is adjusted by acquiring an image of the aligned beam, thereby fixing the tail of the plastic tube by hoisting it.

[0100] In summary, this application includes at least one of the following beneficial technical effects:

[0101] 1. The moving mechanism drives the plastic tube toward the hot melt assembly to complete the hot melt sealing process at the end of the plastic tube;

[0102] 2. When the end of the plastic tube is beveled, the plastic tube will be softened and sealed more evenly;

[0103] 3. As the plastic tube melts and moves, the smoothness of the melt-forming process is improved by rotation, resulting in a more even distribution on the ends of the plastic tube. Attached Figure Description

The hot melt wire 42 abuts against the surface of the deformable part 43. After the plastic pipe is inserted, the operator steps on the clamping pedal 31. Stepping on the clamping pedal 31 energizes the telescopic cylinder 35, which extends. After extension, the control connecting rod 52 drives the rotating gear 34 to rotate, thereby driving the clamping bracket 32 ​​to clamp the plastic pipe. After clamping, the operator manually pushes the push handle 10 towards the hot melt base 38. After pushing, the push rod 14 moves and drives the clamping bracket 32 ​​to move towards the hot melt base 38, thus locking the pipe. The contact point 21 engages with the push rod 14, and the contact block 16 on the push rod 14 abuts against the reset button 27. The reset button 27 controls the reset motor 25 to rotate. During rotation, the thermoelectric wire 42 heats up and is pressed onto the deformable part 43 after heating. Gas is introduced into the deformable part 43 through the air inlet pipe 44 and the air inlet connector 45. After the plastic tube is processed, the reset motor 25 rotates one revolution, and the reset block 29 on the reset gear 28 strikes the return rod 22. The contact point 21 moves away from the push rod 14. Under the action of the return spring 17, the push rod 14 returns to its original position, thus completing the processing of the plastic tube.

[0139] Based on the same inventive concept, embodiments of the present invention provide a method for controlling the high-frequency hot-melt tip forming of a plastic tube, comprising the following steps:

[0140] Step 10: When the reset button 27 is pressed, a push command is issued. In response to the push command, the clamping distance after the plastic tube is clamped is obtained.

[0141] The push command is the command issued after the reset button 27 is pressed. The push command is issued when power is applied after the reset button 27 is pressed.

[0142] The clamping distance refers to the distance after the clamping mechanism 5 clamps the plastic tube. The clamping distance can be obtained by the distance sensor. The model of the distance sensor is selected by the staff according to the actual situation, which will not be elaborated here.

[0143] Step 11: Determine the outer diameter of the plastic tube and the melting temperature of the hot melt wire 42 based on the clamping distance.

[0144] The outer diameter of the plastic tube refers to the outer diameter of the plastic tube. The clamping distance obtained after the plastic tube is clamped by the clamping mechanism 5 is the outer diameter of the plastic tube. The melting temperature refers to the temperature of the hot melt wire 42. The melting temperature can be obtained by detecting the temperature of the hot melt wire 42 by the high temperature sensor. The model of the high temperature sensor is selected by the staff according to the actual situation, and will not be elaborated here.

[0145] Step 12: Calculate the deformation distance based on the outer diameter of the plastic tube, and match the softening rate according to the outer diameter of the plastic tube and the melting temperature.

[0146] The deformation distance refers to the distance from the plastic tube to the surface of the deformed component 43. The deformation distance can be determined by calculating the outer diameter. The specific formula is: Distance = OA - Z = R - (R 2 -r 2 ) 0.5 Where R is the radius of the deformable part 43, OA is the value of the center of the deformable part 43 reaching the top surface. In this embodiment, the shape of the deformable part 43 is hemispherical, that is, R equals OA, Z is the distance from the plastic tube to the top of the deformable part 43, and r is the radius of the plastic tube. If the radius of the deformable part 43 R = 10 mm and the radius of the plastic tube r = 6 mm, then the deformation distance after substituting into the formula is 10 - 8 = 2 mm.

[0147] The softening rate refers to the speed at which the plastic pipe softens. The softening rate can be obtained from the softening data table, which is determined by the staff through experiments for different plastic pipe outer diameters and different melting temperatures. When the melting temperature is constant, the larger the outer diameter of the plastic pipe, the lower the softening rate. When the outer diameter of the plastic pipe is constant, the larger the melting rate, the higher the softening rate.

[0148] Step 13: Match the moving distance based on the softening speed and deformation distance.

[0149] The moving distance is the distance the plastic tube moves in the direction of the deforming part 43. The moving distance can be obtained from the moving data table, which refers to the different moving distances required for different softening speeds and deformation distances, determined in advance by the staff through experiments.

[0150] With a constant softening rate, a larger deformation distance results in a larger movement distance. Conversely, with a constant deformation distance, a faster softening rate results in a larger deformation distance.

[0151] Step 14: Based on the moving distance, drive the plastic tube to move towards the deformable part 43 with a preset moving power until the deformation distance is reached and then stop moving.

[0152] Upon receiving the travel distance, the system controls the movement of the plastic tube. This movement is driven by a motor via gear transmission. The travel power refers to the pre-set power corresponding to different travel distances. The travel distance is recorded after each movement. When the total travel distance reaches the deformation distance, the system stops the motor.

[0154] Step 20: Collect the current moving speed of the plastic tube as it moves toward the deformable part 43 and the clamping weight of the plastic tube when the clamping mechanism 5 clamps it.

[0155] The current moving speed refers to the speed at which the plastic tube moves towards the deformable part 43. This moving speed can be detected by a moving speed sensor, which is selected by the operator based on the actual situation and will not be elaborated here. The clamping weight refers to the weight of the plastic tube being clamped. This clamping weight can be detected by a weight sensor, which is selected by the operator based on the actual situation and will not be elaborated here.

[0156] Step 21: Match the reference moving speed according to the moving power, the outer diameter of the plastic tube and the clamping weight.

[0157] The reference moving speed refers to the moving speed required for the plastic tube to hold the deformed part 43 after melting. The reference moving speed can be obtained from the reference moving speed data table, which refers to the reference moving speed corresponding to different moving power, plastic tube outer diameter and clamping weight determined in advance through experiments.

[0158] With all other conditions remaining unchanged, the reference speed increases when the moving power increases; with all other conditions remaining unchanged, the reference speed decreases when the outer diameter of the plastic tube increases; with all other conditions remaining unchanged, the reference speed decreases when the clamping weight increases; with all other conditions remaining unchanged, the reference speed increases when the moving power increases; and with the outer diameter of the plastic tube remaining unchanged.

[0159] Step 22: Record the movement time point when the current movement speed is the same as the reference movement speed.

[0160] The movement time point refers to the point in time when the current movement speed is the same as the base movement speed. For example, if the movement speed is the same as the base movement speed at 55 seconds, then the movement time point is at 55 seconds.

[0161] Step 23: Match the movement time point with the outer diameter of the plastic tube to determine the additional distance at the movement time point.

[0162] The extra distance is the distance the plastic tube moves. The extra distance can be obtained from the extra data table, which refers to the different extra distances corresponding to different outer diameters of plastic tubes and different moving time points, determined in advance by the staff through experiments.

[0163] Step 24: Calculate the final distance based on the extra distance and the distance traveled.

[0164] The final distance is the sum of the extra distance and the distance traveled. For example, if the extra distance is 1mm and the travel distance is 2mm, then the final distance is 1mm + 2mm = 3mm.

[0165] Step 25: In response to the final distance control, the moving motor drives the plastic tube to move in the direction of the deformable part 43 until the final distance is reached and then stops moving.

[0166] After receiving the final distance, the control motor drives the plastic tube to move towards the deformable part 43 until the final distance is reached and then stops. The model of the moving motor is selected by the staff according to the actual situation, and will not be described here.

[0167] A method for controlling the high-frequency hot-melt tip forming of a plastic pipe, further comprising a rotation method during plastic pipe processing, the rotation method including the following steps:

[0168] Step 30: Obtain the current temperature and the temperature rise time.

[0169] The current temperature refers to the current temperature of the hot melt wire 42. The current temperature can be obtained through a temperature sensor, which is selected by the staff according to the actual situation, and will not be elaborated here.

[0170] The temperature rise time refers to the time it takes for the hot melt wire 42 to reach the current temperature, which can be recorded by a timer. The timer is selected by the staff according to the actual situation, and will not be elaborated here.

[0171] Step 31: Determine the degree of melting of the outer diameter of the plastic tube based on the outer diameter of the plastic tube, the current temperature, and the temperature rise time.

[0172] The degree of melting refers to the extent to which the plastic pipe is melted, that is, the thickness of the melt from the surface inward. The degree of melting can be obtained from the melting data table, which refers to the different degrees of melting corresponding to different outer diameters of plastic pipes, current temperatures, and temperature rise times determined in advance through experiments.

[0173] Step 32: Match the rotation speed based on the degree of melting.

[0174] Rotation speed refers to the rotation speed of the plastic tube. The rotation speed can be obtained from the rotation data table, which is determined in advance through experiments to correspond to different melting degrees. When the melting degree is at the median level, such as 50%, the rotation speed is the highest. When it is below or above the median level, the rotation speed decreases accordingly.

[0175] Step 33: Determine the motor power based on the rotation speed and obtain the current power.

[0176] Motor power refers to the power required by the motor at a given speed to support the rotational speed. Current power refers to the power of the motor at the current rotational speed. Motor power can be obtained by matching from the motor data sheet, which shows the motor power required for different rotational speeds.

[0177] Step 34: Determine the compensation power based on the comparison between the motor power and the current power.

[0178] Compensation power refers to the power difference between the motor power and the current power. Compensation power can be obtained by calculating the difference between the motor power and the current power. For example, if the motor power is 10W and the current power is 8W, then the compensation power is 10-8=2W.

[0179] Step 35: Match the compensation speed based on the compensation power.

[0180] Compensation speed refers to the motor's rotational speed after adding the compensation speed to the current power speed. The compensation speed can be obtained by looking up the compensation data table, which refers to the different compensation speeds corresponding to different compensation powers under different power levels, determined in advance through experiments.

[0181] Step 36: Match the rotation mode according to the difference between the compensation speed and the preset reference speed range. The rotation mode includes intermittent rotation and load rotation.

The rotation mode refers to the rotation method of the plastic tube, which includes intermittent rotation and load rotation.

[0183] Intermittent rotation refers to the rotation mode of the plastic tube when the compensating speed is less than the reference speed range. Intermittent rotation is defined as the number of rotations per unit time and the stop time. For example, rotating 5 times in one minute, pausing after the rotation is completed, and continuing to rotate the plastic tube by inertia after the stop time is reached;

[0184] Load rotation refers to the rotation speed used to compensate for speeds exceeding a preset reference speed range. Load speed refers to the rotation speed that does not stop within a unit of time.

[0185] Step 360: When the compensation speed falls into the preset reference speed range, the rotation mode is intermittent rotation. The intermittent rotation value is determined according to the compensation speed, and the rotor is controlled to rotate the plastic tube based on the intermittent rotation value.

[0186] Intermittent rotation value refers to the number of rotations and the stopping time per unit time. Intermittent rotation value can be obtained from the intermittent rotation data table, which is a table of different intermittent rotation values ​​corresponding to different compensation speeds determined in advance by the staff through experiments.

[0187] Step 361: When the compensation speed does not fall within the preset reference speed range, the rotation mode is load rotation, and the plastic tube is rotated according to the compensation power and rotation speed.

[0188] When the rotation mode is load rotation, the plastic tube is rotated based on the compensation power and rotation speed to complete the compression and sealing of the plastic tube.

[0190] Step 40: Based on the rotation of the plastic tube, a support point is determined by matching the outer diameter of the plastic tube with the clamping weight.

[0191] A support point is a point that supports the unclamped portion of the plastic tube after it is clamped by the clamping mechanism 5. The support point can be matched by substituting the outer diameter of the plastic tube and the clamping weight into the support point data table. The support point data table records different support points corresponding to different outer diameters of plastic tubes and clamping weights.

[0192] Step 41: Determine the length of the line segment based on the outer diameter of the plastic tube.

[0193] The line segment length refers to the length of the line segment that suspends the plastic tube. The line segment length can be obtained from the line segment data table, which refers to the different line segment lengths corresponding to different outer diameters of plastic tubes determined in advance through experiments. The longer the outer diameter of the plastic tube, the longer the line segment length.

[0194] Step 42: Based on the line segment length and support point control line segment, hoist and support the plastic pipe, and after support, control the emission of the alignment beam.

[0195] The plastic pipe is suspended using line segments. After the plastic pipe is supported, the laser machine is controlled to emit a laser. The laser machine is selected by the staff according to the actual situation, which will not be described in detail here.

[0196] Step 43: Acquire an alignment image of the aligned beam and identify the beam position based on the alignment image.

[0197] The alignment image refers to the image after the laser is emitted. The alignment image can be obtained by a camera. The camera model is selected by the staff according to the actual situation, and will not be elaborated here.

[0198] The beam position refers to the position of the laser beam after it is emitted. The beam position can be obtained by acquiring the beam point using image recognition technology.

[0199] Step 44: Determine the offset distance and offset direction based on the beam position and the preset reference position.

[0200] The reference position refers to the point through which the laser passes when the plastic pipe is installed horizontally. The reference position is determined by the staff through experiments and marked after determination. The offset distance and offset direction are determined based on the reference position and the beam position. A cross coordinate system is constructed with the reference position as the origin. The beam position is substituted into the system and connected to the reference position to obtain the line segment length and the direction in which the beam position reaches the reference position.

[0201] Step 45: Change the line segment length based on the offset direction and offset distance until the beam position coincides with the reference position.

[0202] Based on the offset direction and offset distance, the length of the line segment is adjusted to make the beam position coincide with the reference position, so as to reduce the irregular rotation of the rear end of the plastic tube during rotation.

[0204] Step 50: Update the travel distance based on the rotation of the plastic tube.

[0205] The distance the plastic tube travels is updated as the plastic tube rotates.

[0206] Step 51: When the moving distance reaches the deformation distance, update the current temperature.

[0207] When the moving distance reaches the deformation distance, update the current temperature; that is, the temperature of the plastic tube after heating and deformation.

[0208] Step 52: Match the cooling power according to the current temperature and the outer diameter of the plastic tube.

[0209] Cooling power refers to the power to cool down the plastic tube. The cooling power can be obtained by substituting the current temperature and the outer diameter of the plastic tube into the cooling data table. The cooling data table refers to the different cooling powers corresponding to different current temperatures and outer diameters of the plastic tube, which are determined in advance through experiments. That is, when the outer diameter of the plastic tube remains unchanged, the higher the current temperature, the higher the cooling power. When the current temperature remains unchanged, the larger the outer diameter of the plastic tube, the higher the cooling power.

[0210] Step 53: Match the cooling speed based on the cooling power.

[0211] Cooling speed refers to the rotational speed of the plastic tube corresponding to the cooling power. The cooling speed can be determined by matching the cooling correspondence table, which refers to the different cooling speeds corresponding to different cooling powers determined in advance through experiments.

[0212] Step 54: Cool the plastic tube according to the cooling power and rotate the plastic tube according to the cooling speed to shape the plastic tube.

[0213] The plastic tube is cooled by an air pump controlled by the cooling power. The air pump is selected by the operator based on the actual situation, and will not be described in detail here. The plastic tube is rotated by the cooling speed to ensure uniform cooling.
