Description

Technical Field

[0001] The present invention relates to the technical field of strength detection devices, and in particular to a novel strength detection device for processing plastic products. Background Art

[0002] During the processing of plastic products, strength testing is often required to ensure product quality. When conducting strength testing on plastic pipes, the pipes are typically sealed first, and then liquid or air is continuously introduced into the pipes to apply pressure, measuring the maximum pressure at which the pipes suddenly rupture. However, existing plastic pipe strength testing devices require clamps to secure the pipes during strength testing, and then pressure testing each pipe individually using a pressurizing device. This requires repeated assembly and disassembly of the clamps, reducing testing efficiency.

[0003] In the prior art, a sealing airbag is inserted into the end of a plastic product, and the sealing airbag is expanded by inflation to seal the end of the plastic product. Air is injected into the plastic product through an air pressure generating device to perform strength testing. In this method, it is impossible to complete automatic loading, automatic transportation, wall thickness testing, strength testing, and automatic unloading operations of the plastic pipe, thereby reducing the accuracy and efficiency of the plastic pipe strength testing. A movable baffle is used in conjunction with a shell to protect the exploded plastic pipe to prevent the scattering of fragments generated by the explosion. In this method, it is impossible to complete the explosion protection of the plastic pipe and the cleaning of the fragments during the automatic transportation of the plastic pipe, thereby increasing the burden of manual cleaning and reducing the detection efficiency.

[0036] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0037] Reference Figure 1-Figure 3 A novel strength detection device for processing plastic products includes an outer box 1 and further includes:

The loading mechanism includes a chain conveyor 3 arranged on the side of the outer box 1 and a first movable part 5 installed at the bottom of the mounting plate 4. A plurality of placement racks are fixedly connected to the output end of the chain conveyor 3. The bent pipe 18 is placed on the placement rack. One end of the mounting plate 4 passes through the side wall of the outer box 1 and extends to the top of the chain conveyor 3. A clamping part 7 is installed at the output end of the first movable part 5. The clamping part 7 is used to grab the bent pipe 18. A window is opened on the side wall of the outer box 1 for the clamping part 7 and the bent pipe 18 to move.

[0040] The chain conveyor 3 and the clamping part 7 both adopt existing technology. When the chain conveyor 3 is working, its output end transports the bent pipe 18 to the outer box 1 through the placement rack. The clamping part 7 is used to clamp the delivered bent pipe 18, and after moving to the inside of the outer box 1 with the first moving part 5, release the bent pipe 18 to complete the loading operation of the bent pipe 18.

[0041] The rotating mechanism includes a rotatable rotating disk 11 , and a plurality of adjusting components 14 are connected to the rotating disk 11 . The adjusting components 14 are used to receive the bent pipe 18 lowered by the feeding mechanism and adjust the angle of the bent pipe 18 .

[0042] A support plate 8 is fixedly connected to the bottom of the outer box 1, a drive motor is installed at the bottom of the support plate 8, a drive rod 10 is coaxially fixedly connected to the output end of the drive motor, the top of the drive rod 10 passes through the support plate 8, and a rotating disk 11 is coaxially fixedly connected to the top of the drive rod 10.

[0043] The drive motor works, and its output end drives the drive rod 10 to rotate at intervals of 90 degrees, so as to facilitate the transfer of the bent pipe 18 on the adjustment component 14 to different workstations for corresponding inspection operations.

[0044] Reference Figure 3 and Figure 4 The adjustment component 14 includes a second motor 141 mounted on the rotating disk 11, and the output end of the second motor 141 is fixedly connected to an arc block 142. Both ends of the arc block 142 are adjustably fixedly connected to a limit block 143. The top of the arc block 142 is fixedly connected to two limit arc plates 147. The arc block 142 and the top of the two limit blocks 143 and the adjacent sides of the two limit arc plates 147 form an arc groove, and the bent pipe 18 engages with the arc groove.

[0045] The arc block 142 is connected to one of the different limiting holes on the limiting block 143 by a bolt, which facilitates the adjustment of the relative position of the limiting block 143 and the arc block 142, and is convenient for adapting to the curved pipes 18 of different lengths. The bolts on both sides are not coaxial to prevent the limiting block 143 and the arc block 142 from rotating relative to each other.

[0046] A T-shaped bar 144 is slidably connected to the limit block 143, and one end of the T-shaped bar 144 extending into the arc groove is fixedly connected to a locking block 145 and an arc-shaped support plate 146. The locking block 145 is located on the side of the T-shaped bar 144, and a locking groove is provided on the limit block 143 to slide with the locking block 145. The two arc-shaped support plates 146 are located on the adjacent side of the two T-shaped bars 144 and are clearance-matched with the outer side of the bent pipe 18.

[0047] When the engaging block 145 moves downward along with the T-shaped bar 144 , it is engaged with the inner portion of the limiting block 143 , thereby preventing the T-shaped bar 144 from being separated from the limiting block 143 .

[0048] Reference Figure 4-Figure 6 , wall thickness detection mechanism, the wall thickness detection mechanism is located above an adjustment component 14, and is used to detect the wall thickness at both ends of the elbow 18.

[0049] The wall thickness detection mechanism includes a connecting frame fixedly connected to the top of the outer box 1, a first motor 15 is installed at the bottom of the connecting frame, and a connecting plate 16 is fixedly connected to the output end of the first motor 15. A first electric telescopic rod 17 is installed at the bottom of the connecting plate 16, and the output end of the first electric telescopic rod 17 is fixedly connected to an inverted U-shaped fixing plate 19. The top of the U-shaped fixing plate 19 is connected to a V-shaped blocking plate 20. The V-shaped blocking plate 20 includes two vertical plates that are slidably connected to the top of the U-shaped fixing plate 19, and a first spring 21 is fixedly connected between the top of the two vertical plates and the top of the U-shaped fixing plate 19, and the bottom end is fixedly connected to the same V-shaped plate. A detection component 22 is connected to the bottom of the U-shaped fixing plate 19, and the detection component 22 includes two detection structures. The detection ends of the two detection structures are respectively against both sides of the V-shaped plate in the initial state, and against both sides of the axially vertical bend 18 wall at one end in the working state. The output end of the first motor 15 is coaxially arranged with one axially vertical end of the bend 18.

[0050] The connection position between the first electric telescopic rod 17 and the connecting plate 16 is adjustable, thereby facilitating the detection of curved pipes 18 of different thicknesses.

[0051] The two detection structures are correspondingly distributed at the two bottom ends of the U-shaped fixing plate 19. The detection structure includes a mounting block 222 fixedly connected to the inner side of the U-shaped fixing plate 19 and a micro laser sensor 221 installed on the outer side of the U-shaped fixing plate 19. A light-through groove for the laser to pass through is provided on the U-shaped fixing plate 19. A detection groove is provided through the middle of the mounting block 222. The detection groove is connected to the light-through groove. A T-shaped rod 223 is slidably connected inside the detection groove. A second spring 224 is fixedly connected between the T-shaped rod 223 and the mounting block 222. The laser emitted by the micro laser sensor 221 passes through the light-through groove and the detection groove and is irradiated on the T-shaped rod 223. The end of the T-shaped rod 223 away from the micro laser sensor 221 rests on the side of the V-shaped plate. The two micro laser sensors 221 and the two T-shaped rods 223 are coaxially arranged.

[0052] The ends of the two T-shaped rods 223 are initially separated from each other by the V-shaped plate, which facilitates the wall of the bent pipe 18 to enter between the two T-shaped rods 223 and facilitates the wall thickness detection operation.

[0053] The micro laser sensor 221 adopts the existing technology and detects the distance between it and the T-bar 223 through laser, so as to conveniently know the position change of the T-bar 223 when it is transferred from the V-plate to the wall of the bend 18, and finally know the thickness of the wall of the bend 18 through two detection structures.

[0054] Reference Figure 3 、 Figure 7 、 Figure 8 and Figure 10, strength detection mechanism, the strength detection mechanism includes an air pump 2, a protective shell 13 and a movable baffle 23. The bottom of the baffle 23 is connected to a sealing clamping assembly, which is used to seal and clamp the two ends of the elbow 18. When the baffle 23 moves, it is used to place the elbow 18 into the interior of the protective shell 13 through the sealing clamping assembly. The air pump 2 is used to inflate the interior of the elbow 18 through the sealing clamping assembly.

[0055] The air pump 2 adopts existing technology and is used to inflate the inside of the sealed elbow 18 to increase the power of strength testing.

[0056] A second movable part 6 is installed at the bottom of the mounting plate 4, and a baffle plate 23 is fixedly connected to the output end of the second movable part 6. The sealing clamping assembly includes two second electric telescopic rods 24 rotatably mounted on the bottom of the baffle plate 23. The output end of the second electric telescopic rod 24 is fixedly connected to a piston 25. When the output ends of the two second electric telescopic rods 24 are extended, the two pistons 25 are pushed to seal the two ends of the elbow 18 respectively. The adjacent sides of the two pistons 25 and the interior of the elbow 18 form a sealed blasting space. A hose is fixedly connected to one piston 25, one end of the hose is connected to the blasting space, and the other end is connected to the output end of the air pump 2. A pressure sensor 26 is installed on the other piston 25. The pressure sensor 26 is used to detect the air pressure in the blasting space. A slot for the hose to extend into is provided at the top of the protective shell 13.

[0057] The first movable part 5 and the second movable part 6 both adopt existing technology, and both include an electric slide rail and an electric push rod installed on the output end of the electric slide rail. The electric slide rail controls the electric push rod to move linearly in the horizontal direction, and the electric push rod controls its output end to move linearly in the vertical direction, which is convenient for adjusting the connected clamping part 7 or the baffle 23 to move in the vertical plane.

[0058] The angle of the second electric telescopic rod 24 on the shielding plate 23 is adjusted and locked by the existing angle adjustment component, so as to facilitate matching with the elbows 18 of different angles and improve adaptability.

[0059] A rotatable buffer disk 28 is connected to the inside of the protective shell 13. The lower surface of the baffle 23, the inside of the protective shell 13, and the upper surface of the buffer disk 28 form a protective space. An end gear 30 is coaxially fixedly connected to the drive rod 10. The end gear 30 is engaged with a helical gear 29. A connecting rod that passes through the protective shell 13 is fixedly connected between the helical gear 29 and the buffer disk 28. The axial direction of the connecting rod passes through the center of the buffer disk 28. Rubber pads are fixedly connected to the upper and lower surfaces of the buffer disk 28.

[0060] The connecting rod is rotatably connected to the protective shell 13 to drive the buffer tray 28 to flip.

[0061] The rubber pad is used to cushion the fragments generated by the explosion of the elbow 18, and the protective space is used to shield and collect the fragments, so that the fragments can be quickly cleaned up.

[0062] Reference Figure 3 、 Figure 9 and Figure 10 , a blanking mechanism, which is used to transport the bent pipes 18 that fail the wall thickness test and the bent pipes 18 that have passed the strength test out of the interior of the outer box 1.

[0063] The unloading mechanism includes multiple rotating components 27 connected to the rotating disk 11 and a first conveyor 9 and a second conveyor 12 arranged on the outside of the outer box 1. The multiple rotating components 27 correspond one-to-one to the multiple adjustment components 14. The second conveyor 12 partially extends into the interior of the outer box 1 and is located below another adjustment component 14. The first conveyor 9 partially extends into the interior of the outer box 1 and is located below the protective shell 13.

[0064] The first conveyor 9 and the second conveyor 12 are both existing technologies, and are used to convey the components dropped thereon to the outside.

[0065] The rotating assembly 27 includes a rotating rod 272 rotatably connected to the inside of the rotating disk 11, a rotation damper 271 is installed between the end of the rotating rod 272 and the inside of the rotating disk 11, and a torsion spring 273 is fixedly connected between the side and the inside of the rotating disk 11. The end of the rotating rod 272 away from the rotation damper 271 is fixedly connected to a rotating plate 275, and a through groove for the rotating plate 275 to rotate is opened on the rotating disk 11. The through groove is located directly below the arc block 142, and a blocking block 274 is fixedly connected to the end of the through groove away from the rotating rod 272. The blocking block 274 abuts against the top of the rotating plate 275. When the arc block 142 rotates, it pushes the rotating plate 275 to rotate downward and open, and allows the bent pipe 18 to fall onto the output end of the second conveyor 12 through the through groove.

[0066] The rotation damper 271 adopts the existing technology to hinder the rotation of the rotating plate 275, slow down its rotation speed, and ensure its working effect.

[0067] When the present invention is used, when inspecting the right-angled bend 18, the feeding operation of the bend 18 is performed first, the chain conveyor 3 works, and its output end conveys the bend 18 to the bottom of the clamping part 7 through the placement rack, the clamping part 7 works, clamps the bend 18 from both ends, and the first moving part 5 works, driving the clamping part 7 to move into the interior of the outer box 1 until the bend 18 is moved to the inside of the placement slot of an adjustment component 14, and the clamping part 7 releases the clamping of the bend 18 and returns to its original position, completing the feeding operation of the bend 18.

[0068] The curved pipe 18 is located inside the placement groove, and the two sets of limiting arc plates 147 are used to limit the side surfaces of the curved pipe 18. At this time, the inner curved surface of the arc block 142 faces upward.

[0069] At this time, the transfer operation of the bent pipe 18 inside the outer box 1 is carried out, and the drive motor at the lower end of the support plate 8 works, and its output end drives the drive rod 10 to rotate, rotating at intervals of 90 degrees. The drive rod 10 drives the rotating disk 11 to rotate, and drives the adjustment component 14 with the bent pipe 18 to rotate to the wall thickness detection mechanism.

[0070] At this time, the preparation operation for the wall thickness detection of the bent pipe 18 is carried out. First, the second motor 141 in the adjustment component 14 is put into operation, and its output end drives the arc block 142 to rotate, thereby driving the bent pipe 18 on it to rotate 45 degrees, so that one end of the bent pipe 18 remains in a vertical state. When the arc block 142 rotates, the T-bar 144 at its bottom moves downward and contacts the rotating plate 275. Under the obstruction of the rotating plate 275, the T-bar 144 stops moving, thereby lifting the bent pipe 18 through the arc support plate 146, making it convenient for the bent pipe 18 to move to the wall thickness detection mechanism, and completing the preparation work for the wall thickness detection of the bent pipe 18.

[0071] Then the wall thickness of the bent pipe 18 is detected. The output end of the first electric telescopic rod 17 in the wall thickness detection mechanism is extended, driving the U-shaped fixing plate 19 to move downward until the bottom end of the V-shaped plate in the V-shaped blocking plate 20 contacts the wall of the bent pipe 18. The U-shaped fixing plate 19 continues to move downward, and the wall of the bent pipe 18 blocks the V-shaped plate, so that the wall of the bent pipe 18 gradually replaces the V-shaped plate, and then the ends of the T-shaped rods 223 that originally rested on both sides of the V-shaped plate are transferred to the inner and outer sides of the wall of the bent pipe 18.

[0072] The two groups of micro laser sensors 221 work to detect the distance between themselves and the T-bar 223. Based on the pre-known distance between the two micro laser sensors 221 and the length of the T-bar 223, the wall thickness of the curved pipe 18 can be calculated, or the wall thickness of the curved pipe 18 can be directly calculated based on the displacement of the two T-bars 223.

[0073] Subsequently, the first motor 15 works, and its output end drives the connecting plate 16 to rotate, thereby driving the U-shaped fixing plate 19 to rotate coaxially around the bent pipe 18 through the first electric telescopic rod 17. By coordinating the extension and retraction of the output end of the first electric telescopic rod 17 and adjusting the detection height, a comprehensive detection of the wall thickness at the end of the bent pipe 18 can be achieved.

[0074] By comparing the calculated value with the designed thickness of the elbow 18 , it can be determined whether there are defects such as bubbles and depressions at the inspection position of the elbow 18 that affect the wall thickness.

[0075] After one end of the bent pipe 18 is inspected, the U-shaped fixing plate 19 is moved upward by the first electric telescopic rod 17, so that the T-shaped rod 223 is separated from the wall of the bent pipe 18. During this process, the V-shaped blocking plate 20 maintains a distance between the two groups of T-shaped rods 223 under the elastic force of the first spring 21, making it easier for the subsequent bent pipe 18 to be embedded between the two groups of T-shaped rods 223. There is no need to set up an electric control adjustment structure, which reduces equipment cost and equipment complexity.

[0076] The second motor 141 is used to rotate the bend pipe 18 in the opposite direction by 90 degrees, so that the other end of the bend pipe 18 opens vertically upward, and then the detection process is repeated to complete the wall thickness detection of the two end ports of the bend pipe 18.

[0077] After the wall thickness is detected, the adjustment assembly 14 and the wall thickness detection mechanism are reset.

[0078] Since the shape of the elbow 18 will affect the sealing effect of the subsequent strength detection mechanism, and the data error rate obtained from the detection of unqualified elbows 18 is relatively large, the accuracy and efficiency of the strength detection will be reduced.

[0079] Therefore, if the test fails, the rotating disk 11 rotates, and drives the bent pipe 18 to rotate to the top of the second conveyor 12 through the adjusting component 14.

[0080] The second motor 141 in the adjustment assembly 14 works, and its output end drives the arc block 142 to rotate downward. The arc block 142 rotates and pushes the rotating plate 275 through the limit block 143, so that the rotating plate 275 rotates to open the through slot, making it convenient to dump the bent pipe 18 through the through slot to the second conveyor 12. The second conveyor 12 works to convey the bent pipe 18 with unqualified wall thickness out of the interior of the outer box 1.

[0081] The blocking block 274 is fixed on the rotating disk 11 and is arranged in contact with the upper surface of the rotating plate 275 to block the rotating plate 275 from rotating upward.

[0082] The torsion spring 273 is used to reset the rotating plate 275. The rotating damper 271 is used to slowly reset the rotating plate 275 so that the bent pipe 18 has enough time to be conveyed, thereby preventing the rotating plate 275 from rebounding quickly and knocking the bent pipe 18 off the second conveyor 12.

[0083] If the wall thickness of the bent pipe 18 passes the inspection, the rotating disk 11 rotates, and the bent pipe 18 is moved to the bottom of the shielding plate 23 through the adjusting assembly 14 .

[0084] The strength test of the curved pipe 18 is started. First, the output ends of the two second electric telescopic rods 24 at the bottom of the baffle 23 are extended, and the pistons 25 are embedded in the ends of the curved pipe 18 for squeezing and sealing. One group of pistons 25 is connected to the air pump 2 through a hose, and the other group of pistons 25 is embedded and fixedly connected with a pressure sensor 26. The pressure sensor 26 is used to detect the pressure inside the curved pipe 18.

[0085] Then the second moving part 6 works to move the sealed and clamped elbow 18 into the protective shell 13 through the shielding plate 23, the second electric telescopic rod 24 and the piston 25. At this time, the shielding plate 23 blocks the upper end of the protective shell 13.

[0086] Then the air pump 2 pressurizes the inside of the bend 18 through the hose until the bend 18 is exploded, and the bursting strength of the bend 18 is detected by the pressure sensor 26. Rubber pads are provided at the upper and lower ends of the buffer plate 28. When the fragments generated by the explosion of the bend 18 hit the buffer plate 28, the deformation of the rubber pad effectively reduces the impact rebound of the fragments, thereby reducing the impact on the protective shell 13 and the buffer plate 28 and improving the service life.

[0087] The circumference of the bevel gear 29 is half of the end gear 30. When the end gear 30 rotates 90 degrees, the bevel gear 29 rotates 180 degrees. When the next set of curved pipes 18 is inspected, the buffer plate 28 will rotate 180 degrees driven by the bevel gear 29. During the rotation, the fragments will fall onto the first conveyor 9. The first conveyor 9 works to transport the fragments.

[0088] As the next group of bends 18 explode, the impact on the buffer tray 28 will promote the falling of debris adhered to the lower end of the buffer tray 28, effectively preventing residual debris on the upper surface of the buffer tray 28 when it rotates back to its initial state, thereby preventing the explosion fragments of the next group of bends 18 from colliding with the residual fragments, ensuring the cushioning effect of the rubber pad, and realizing the dumping and transportation of debris at the same time, without the need for manual shutdown for cleaning, thereby improving efficiency.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
