[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1

[0040] To solve the technical problems in the background art, the following is a kind of automatic blanking and trimming device for composite pipes:

[0041] Combined with Figures 1-11 As shown, a kind of automatic blanking and trimming device for composite pipes provided by the present invention includes:

[0042] A base 1, on the top of the base 1, two brackets 11 with a vertically inverted U-shaped cross-section are symmetrically and fixedly installed. A horizontally arranged first rotating shaft 12 is rotatably installed between the two brackets 11. A first motor 13 connected to the first rotating shaft 12 is fixedly installed on one of the brackets 11. Four groups of positioning mechanisms 2 for positioning pipes are annularly and arrayedly installed on the outer side wall of the first rotating shaft 12;

[0043] The guiding and feeding assembly 3 is fixedly installed on the top of the base 1 and is located on one side of the two brackets 11. The guiding and feeding assembly 3 is used to guide and feed the pipe so that one of the positioning mechanisms 2 can position the pipe. Specifically, one end of the guiding and feeding assembly 3 is connected to the conveying end of a conveyor outside for conveying the processed pipe;

[0044] There are two connecting plates 4. The two connecting plates 4 are symmetrically and slidably installed on the other side of the two brackets 11 along the axis direction of the first rotating shaft 12. An electromagnetic slider 14 connected to the connecting plate 4 is fixedly installed on the base 1. The end of the connecting plate 4 extends directly above the first rotating shaft 12 and is equipped with a grinding mechanism 5, which is used to grind the end of the pipe;

[0045] A patch mechanism 6 is provided. A guide rail 41 is fixedly installed on one side of the connecting plate 4 close to the bracket 11. A sliding block 42 is slidably installed on the guide rail 41 along the axis direction of the first rotating shaft 12. An electromagnetic slider 43 connected to the sliding block 42 is fixedly installed on the guide rail 41. The patch mechanism 6 is installed on the sliding block 42. The patch mechanism 6 is used to attach a protective ring to the end of the pipe that has been ground by the grinding mechanism 5. It should be noted that the protective ring is made of polyethylene material. A conveyor belt 15 is fixedly installed between the opposite sides of the two brackets 11 and directly below the first rotating shaft 12, which is used to convey the trimmed pipe.

[0046] During use, when the external conveyor conveys the processed pipes to the conveying end of the conveyor, the pipes are conveyed to the guiding assembly 3 and then guided to one side of the first rotating shaft 12. At this time, the first motor 13 is controlled to rotate the first rotating shaft 12 on the two brackets 11, driving multiple groups of positioning mechanisms 2 to rotate around the first rotating shaft 12. When one group of positioning mechanisms 2 rotates around the first rotating shaft 12 to the position of the guiding assembly 3, the pipes can be positioned by the positioning mechanism 2 close to the guiding assembly 3. Then, the first rotating shaft 12 is rotated on the two brackets 11 to displace the pipes to be polished to directly above the first rotating shaft 12. At this time, the two connecting plates 4 are brought closer to each other by the two electromagnetic sliders 14, driving the two grinding mechanisms 5 to contact the two ends of the pipes respectively. At this time, the two grinding mechanisms 5 can perform grinding operations on the two ends of the pipes respectively. During this period, an adjacent group of positioning mechanisms 2 is located at the guiding assembly 3, so that the next pipe to be polished can be positioned; after the grinding treatment of the pipe located above the first rotating shaft 12 is completed, the first motor 13 is controlled to rotate the first rotating shaft 12 on the two brackets 11 to rotate the polished pipe to the side of the first rotating shaft 12 away from the guiding assembly 3. At this time, the polished pipe is located between the two patch mechanisms 6. At this time, the two patch mechanisms 6 respectively attach protective rings to the two ends of the pipe. During this period, the pipe positioned on the positioning mechanism 2 on the side of the first rotating shaft 12 away from the patch mechanism 6 rotates to above the first rotating shaft 12, and the two grinding mechanisms 5 can perform grinding operations on the two ends of the pipe respectively. The positioning mechanism 2 close to the guiding assembly 3 positions the next pipe to be polished; when the end grinding of the pipe located above the first rotating shaft 12 is completed and the protective ring patching of the two ends of the pipe located between the two patch mechanisms 6 is completed, the first motor 13 is controlled to rotate the first rotating shaft 12 on the two brackets 11, so that the pipe after the protective ring patching treatment is located above the conveyor belt 15. The positioning of the pipe after the protective ring patching treatment by the positioning mechanism 2 is cancelled, and the pipe after the protective ring patching treatment can be dropped onto the conveyor belt 15, so as to convey and discharge the pipe after the protective ring patching treatment through the conveyor belt 15. During this period, the two grinding mechanisms 5 and the two patch mechanisms 6 respectively perform synchronous operations on other pipes to be trimmed, achieving one-time trimming of the pipes from loading to unloading, replacing the current operation mode of sequentially transferring the pipes to the grinding equipment and the patching equipment, reducing the pipe transfer time during the pipe trimming operation, thus greatly shortening the time required for pipe trimming and improving work efficiency.

[0047] In this embodiment, the positioning mechanism 2 includes positioning components symmetrically installed on the outer sidewall of the first rotating shaft 12. The positioning components include a connecting seat 21 fixedly installed on the first rotating shaft 12. The ends of the connecting seat 21 are symmetrically hinged with arc-shaped clamping plates 22. The connecting seat 21 is symmetrically installed with a first driving rod 23 for driving the arc-shaped clamping plates 22 to rotate on the connecting seat 21. During use, the coil is placed between the opposite sides of the two arc-shaped clamping plates 22 on the two positioning components, and then the first driving rods 23 on the two positioning components are controlled to make the two arc-shaped clamping plates 22 on the positioning components rotate on the connecting seat 21, so that the two arc-shaped clamping plates 22 on the positioning components are in contact with the pipe, thereby realizing the clamping and positioning effect of the pipe through the two positioning components, which is convenient for control.

[0048] In this embodiment, the guiding and feeding component 3 includes a bottom plate 31 fixedly installed on the base 1. The top of the bottom plate 31 is linearly arranged in a horizontal direction with guiding and feeding units. The guiding and feeding units include support frames 32 symmetrically and fixedly installed on the top of the bottom plate 31. The top of the support frames 32 is rotatably installed with inclined guiding and feeding rollers 33. An inverted V shape is formed between the two guiding and feeding rollers 33. Specifically, it should be noted that: the arc-shaped clamping plate 22 can movably penetrate between two adjacent groups of guiding and feeding units. During use, when an external conveyor conveys the processed pipe to the conveying end of the conveyor, the pipe is displaced above the guiding and feeding rollers 33 on the guiding and feeding component 3. During the conveying of the pipe by the external conveyor, when the pipe contacts the guiding and feeding rollers 33, the guiding and feeding rollers 33 rotate on the support frames 32 to achieve the guiding and feeding effect of the pipe.

[0049] Embodiment Two

[0050] As Figures 1-11 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0051] In this embodiment, the grinding mechanism 5 is horizontally arranged and a second rotating shaft 51 rotatably installed on the connecting plate 4. The second rotating shaft 51 is located directly above the first rotating shaft 12. The top of the second rotating shaft 51 is installed with a mounting plate 52. The mounting plate 52 is installed with a grinding component 53 for grinding the surface of the end of the pipe. The connecting plate 4 is installed with a driving component 54 for driving the second rotating shaft 51 to rotate. When the grinding component 53 rotates around the second rotating shaft 51, the end of the pipe is ground by the grinding component 53. During use, when the two electromagnetic sliders 14 make the two connecting plates 4 approach each other, driving the two grinding mechanisms 5 to contact the two ends of the pipe respectively, the grinding component 53 contacts the end of the pipe. During this period, the driving component 54 is controlled to make the second rotating shaft 51 rotate, so as to drive the grinding component 53 to rotate around the second rotating shaft 51 through the mounting plate 52, thereby realizing the grinding treatment effect on the end of the pipe.

[0052] In this embodiment, the grinding assembly 53 includes a hinge block 531 hinged to one end of the mounting plate 52. A second motor 532 for driving the hinge block 531 to rotate is fixedly installed on the mounting plate 52. A mounting shaft 533 is rotatably installed on the hinge block 531. A third motor 534 for driving the mounting shaft 533 to rotate is fixedly installed on the hinge block 531. A grinding head 535 that can contact the end of the pipe is fixedly installed at the end of the mounting shaft 533. During use, when the two electromagnetic sliders 14 bring the two connecting plates 4 closer to each other, driving the two grinding mechanisms 5 to contact the two ends of the pipe respectively, the grinding head 535 contacts the end of the pipe. During this period, the third motor 534 is controlled to rotate the mounting shaft 533, driving the grinding head 535 to rotate around the mounting shaft 533. With the cooperation of the driving assembly 54, the grinding effect on the end of the pipe can be achieved. By setting the hinge block 531 to be hinged on the mounting plate 52, when it is necessary to grind the edge of the end of the pipe, the hinge block 531 is rotated on the mounting plate 52 by the second motor 532, so that the grinding head 535 can be tilted. At this time, with the sliding cooperation of the two connecting plates 4 by the two electromagnetic sliders 14, the grinding head 535 can contact the edge of the end of the pipe. With the cooperation of the third motor 534 and the driving assembly 54, the edge of the end of the pipe can be ground.

[0053] In this embodiment, the driving assembly 54 includes a fourth motor 541 fixedly installed on the connecting plate 4. A first pulley 542 is fixedly installed on the output shaft of the fourth motor 541. A second pulley 543 is coaxially fixed to the second rotating shaft 51. A transmission belt 544 is connected between the first pulley 542 and the second pulley 543. During use, the fourth motor 541 is controlled to start. The output shaft of the fourth motor 541 rotates to drive the first pulley 542 to rotate. At this time, under the action of the transmission belt 544, the second rotating shaft 51 is driven to rotate on the connecting plate 4, which is convenient for control.

[0054] Embodiment 3

[0055] As Figures 1-11 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0056] In this embodiment, a fixing plate 44 is fixedly installed at the top of the connecting plate 4 and on the side of the bracket 11 away from the support frame 32. Vertically symmetric telescopic rods 45 are fixedly installed on the fixing plate 44. The bottoms of the two telescopic rods 45 are fixedly installed with a connecting block 46. A second driving rod 47 connected to the connecting block 46 is fixedly installed on the fixing plate 44. A hot melt plate 48 for hot melting the end of the pipe is fixedly installed at the bottom of the connecting block 46. Specifically, it should be noted that: the hot melt plate 48 is internally provided with an electric heating wire for heating the hot melt plate 48 itself. When the grinding head 535 contacts the edge of the pipe end, the hot melt plate 48 contacts the pipe end. The patch mechanism 6 is used to attach a protective ring to the hot-melted pipe end. When attaching the protective plate, the hot melt plate 48 is electrified, and the second driving rod 47 is controlled to displace the connecting block 46 along the two telescopic rods 45, so that the hot melt plate 48 is located on one side of the pipe end. Through the two electromagnetic sliders 14, the two connecting plates 4 are slidably matched, so that when the grinding head 535 contacts the edge of the pipe end, the hot melt plate 48 contacts the pipe end. The hot melt plate 48 is electrified and its temperature rises, so that when it contacts the pipe end, the hot melting treatment effect of the pipe end can be achieved. At this time, the second driving rod 47 is controlled to reset the connecting block 46, and then the electromagnetic slider 43 is used to make the sliding block 42 approach the pipe on the guide rail 41, driving the patch mechanism 6 to displace towards the pipe so that the protective ring contacts the pipe end, and the protective ring can be attached to the hot-melted pipe end, realizing the effect of attaching a protective ring to the pipe end.

[0057] In this embodiment, the patch mechanism 6 includes a conveying seat 61 fixedly installed on the top of the sliding block 42. An accommodation cavity 611 for accommodating the protective ring is formed inside the conveying seat 61. One side of the accommodation cavity 611 close to the hot melt plate 48 is open. A replenishing port 612 communicating with the inside of the accommodation cavity 611 is formed at one end of the top of the conveying seat 61 away from the hot melt plate 48. Through holes 613 communicating with the inside of the accommodation cavity 611 are formed on both sides of the conveying seat 61. A third driving rod 62 is fixedly installed at one end of the conveying seat 61 away from the hot melt plate 48. The piston rod of the third driving rod 62 extends into the accommodation cavity 611 and a push plate 63 is fixedly installed. During use, the push plate 63 is displaced to the side of the replenishing port 612 away from the open end of the accommodation cavity 611 through the third driving rod 62. The protective ring is fed into the accommodation cavity 611 through the replenishing port 612. After the end of the pipe is heat-melted by the hot melt plate 48, it is controlled that the sliding block 42 moves towards the pipe on the guide rail 41 through the electromagnetic slider two 43, driving the conveying seat 61 to approach the end of the pipe. When the end of the pipe is inserted into the accommodation cavity 611, the third driving rod 62 is controlled to displace the push plate 63 towards the open end of the accommodation cavity 611, and then the protective ring located in the accommodation cavity 611 can be pushed to contact the end of the pipe, attaching the protective ring to the end of the heat-melted pipe. Among them, in this embodiment, one end of the hot melt plate 48 close to the conveying seat 61 can extend into the accommodation cavity 611. When the end of the pipe is heat-melted by the hot melt plate 48, the sliding block 42 moves towards the pipe on the guide rail 41 through the electromagnetic slider two 43, driving the conveying seat 61 to approach the end of the pipe, so that the end of the hot melt plate 48 is inserted into the accommodation cavity 611. The third driving rod 62 is controlled to displace the push plate 63 towards the open end of the accommodation cavity 611, and then the protective ring located in the accommodation cavity 611 can be pushed to contact the hot melt plate 48, achieving the effect of heat-melting the surface of the protective ring. After the end of the pipe is heat-melted subsequently, when the protective ring is attached to the end of the heat-melted pipe, the connection stability between the protective ring and the end of the pipe is improved, and the protection effect on the end of the pipe is enhanced; through the design of the through holes 613, it is convenient to penetrate the stock quantity of the protective ring in the accommodation cavity 611.

[0058] In this embodiment, a cleaning mechanism 7 is installed on the base 1 and above the two mounting plates 52. The cleaning mechanism 7 is used to clean the dust generated by grinding the end of the pipe. By setting the cleaning mechanism 7, when the grinding mechanism 5 grinds the end of the pipe, the cleaning mechanism 7 cleans the dust generated by grinding the end of the pipe, effectively avoiding the situation that the dust generated during the grinding of the end of the pipe is emitted into the ambient air and reducing the ambient air quality.

[0059] In this embodiment, the cleaning mechanism 7 includes a negative pressure box 71 fixedly installed on the top of the base 1. Connecting frames 111 are fixedly installed on both of the two brackets 11. An expansion hood 72 is fixedly installed on the connecting frame 111 and directly above the mounting plate 52. A communicating pipe 73 that is connected through the negative pressure box 71 and communicates with the interiors of both expansion hoods 72 is provided. An installation hole 711 that communicates with the interior of the negative pressure box 71 is formed in the negative pressure box 71. An air extraction fan 74 is fixedly installed in the installation hole 711 of the negative pressure box 71. One side of the negative pressure box 71 is open. A sealing plate 75 for sealing the open end thereof is hinged on the negative pressure box 71. The sealing plate 75 and the negative pressure box 71 are fixed by a buckle, which facilitates fixing or canceling the fixation between the sealing plate 75 and the negative pressure box 71, and facilitates sealing or canceling the sealing of the open end of the negative pressure box 71. A collection box 76 with an open top is placed in the negative pressure box 71 and directly below the installation hole 711. A filter plate 77 for sealing the installation hole 711 is fixedly installed in the negative pressure box 71. During use, the air extraction fan 74 is controlled to start. The air extraction fan 74 operates to extract the air inside the negative pressure box 71 outward, so that a negative pressure is formed inside the negative pressure box 71. At this time, the air below the two expansion hoods 72 flows into the negative pressure box 71 through the communicating pipe 73, thereby realizing the inhalation of the dust generated when the grinding mechanism 5 grinds the end of the pipe into the negative pressure box 71. When the air circulates, when the air inside the negative pressure box 71 is discharged outward through the installation hole 711, the filter plate 77 filters the air dust, so that the dust remains in the negative pressure box 71, achieving the effect of cleaning the dust generated when grinding the end of the pipe; through the design of the collection box 76, the dust remaining in the negative pressure box 71 falls into the collection box 76 under the action of its own gravity, and the dust is collected by the collection box 76. When cleaning the dust collected in the negative pressure box 71, the sealing state of the sealing plate 75 for the open end of the negative pressure box 71 is canceled, and the collection box 76 can be taken out of the negative pressure box 71, thereby facilitating the treatment of the dust collected in the collection box 76.
