Description

Technical Field

[0001] The invention relates to the technical field of heat shrink tube detection, and in particular to an integrated device for detecting foreign matter in an in-line heat shrink tube and cutting and connecting the tube. Background Art

[0002] The general production process of heat shrink tubing is to first mix the polymer raw materials with additives, extrude and shape them, cool them, then perform radiation cross-linking, then heat and expand them, cool them to shape them, and finally cut, test and package them into finished products.

[0003] During the extrusion process of heat shrink tubes, the residue in the extruder may be mixed into the heat shrink tube, which will affect the performance of the heat shrink tube and lead to poor quality of the heat shrink tube. Because the foreign matter in the heat shrink tube varies in size, it is sometimes difficult to accurately identify it, which leads to low-quality heat shrink tubes flowing into the client and causing customer complaints. Moreover, the manual intervention detection method will inevitably consume a large manpower cost. After the foreign matter in the tube is found, it will also cause the production process to be interrupted because it cannot be handled in time. Therefore, a device is needed to perform online detection of foreign matter in the heat shrink tube, automatically cut off the foreign matter segment, and reconnect it to ensure the production quality of the heat shrink tube, reduce manual intervention, and keep up with the production rhythm.

The tube cutting mechanism 5 and the gluing mechanism 6 are located between the first flipping mechanism and the second flipping mechanism. The detection traction mechanism 2 and the sealing mechanism 3 are arranged in sequence between the front traction mechanism 1 and the first flipping mechanism. The rear traction mechanism 7 is arranged on the rear side of the second flipping mechanism. The heat shrink tube 10 can pass through the front traction mechanism 1 and the mechanism housing 9 in sequence. The detection traction mechanism 1 includes displacement sensors 2-7 for detecting changes in the thickness of the heat shrink tube.

[0066] In a specific embodiment of the present invention, the mechanism housing 9 includes a main substrate 9-1, a mechanism cover 9-2 located above the main substrate, and a substrate bracket 9-3 located below the main substrate. An electronic control component 8 is provided on the mechanism housing 9, and a front traction mechanism 1 is provided on the front side of the mechanism cover 9-2 and a blanking frame 11 is provided on the rear side.

[0067] In this embodiment, if Figure 3As shown, the front traction mechanism 1 mainly includes: a first traction base plate 1-16, a first limiting roller assembly 1-1 is placed at the front end of the first traction base plate 1-16, a first motor 1-3 is placed on the first traction base plate 1-16, and a first active roller assembly 1-2 is placed on the output shaft of the first motor 1-3; a first driven roller assembly 1-4 is placed on the first traction base plate 1-16 through a first driven roller connecting component, wherein the first driven roller connecting component includes a first swing rod 1-5 and a first cantilever pin 1-6, that is, the first driven roller assembly 1-4 is placed on the first traction base plate 1-16 through the first swing rod 1-5 and the first cantilever pin 1-6, and is located above the first active roller assembly 1-2; two rollers 1-7 are placed on the first traction base plate 1-16 through a roller connecting component, wherein the roller connecting component includes a second swing rod Rod 1-8, first shaft 1-14, first seat bearing 1-9, that is, two rollers 1-7 are placed on the first traction base plate 1-16 through the second swing rod 1-8, the first shaft 1-14, and the first seat bearing 1-9. The specific connection relationship is that the first seat bearing 1-9 is fixedly arranged on the first traction base plate 1-16, and the first seat bearing 1-9 is rotatably connected to one end of the second swing rod 1-8 through the first shaft 1-14, and the other end of the second swing rod 1-8 is fixedly connected to two rollers 1-7 arranged oppositely.

The front traction mechanism 1 is placed on the main base plate 9-1 through the first connecting plate 1-15. The front traction mechanism 1 of this device is connected to the rear end of the heat shrink tube expansion process. Because the expansion process at the front end will continue, the first motor 1-3 will continue to pull the heat shrink tube. However, during the subsequent sealing and tube cutting process, the rear traction motor will stop working, resulting in the heat shrink tubes being piled up at the front traction mechanism 1. When the heat shrink tubes are stacked, the tube body will sag, causing the second swing rod 1-8 to sag. After the first sensor 1-11 detects it, when the hole plugging and pipe connection are completed, the rear motor will accelerate the traction and gradually straighten the heat shrink tube.

Unless otherwise specified, commonly used connecting structural components and connection methods in the field of mechanical design are adopted and will not be elaborated.

[0081] The specific working process of the on-line hole plugging detection device for shrinking tubes in this embodiment is as follows:

[0082] Work preparation: Put the adhesive tape 6-3-3 into the adhesive tape holder assembly 6-3-1 and fix it. Pass one end of the adhesive tape 6-3-3 through the third shaft 6-3-14 and press it under the top piece 6-3-12. Use the fifteenth cylinder 6-3-9 to push the first downward pressing rubber head 6-3-11 to clamp one end of the adhesive tape 6-3-3 and expose about 10mm of the adhesive tape head.

[0083] Adjust the roller width of the first limiting roller assembly 1-1 and the second limiting roller assembly 7-15 to match the width of the heat shrink tube 10. After the heat shrink tube is expanded, pass the heat shrink tube through the first limiting roller assembly 1-1, the first active roller assembly 1-2, the roller 1-7, the third active roller assembly 2-1, the cold pressing bottom plate 3-4, the pressing bottom plate 4-7, the first movable bottom plate 5-3-1; the second movable bottom plate 5-3-2, the pressing bottom plate 4-7, the second limiting roller assembly 7-15, the second active roller assembly 7-1 to the blanking frame 11, close the mechanism cover 9-2, and start the equipment.

[0084] 1) The heat shrink tube circulates in the whole device: the first cylinder 2-14 on the detection traction mechanism 2 drives the third driven roller assembly 2-10 to press down, and the sixteenth cylinder 7-11 on the rear traction mechanism 7 drives the second driven roller assembly 7-7 to press down. Afterwards, the first motor 1-3 drives the first active roller assembly 1-2 to rotate, the second motor 2-4 drives the third active roller assembly 2-1 to rotate, and the sixth motor 7-4 drives the second active roller assembly 7-1 to rotate, and the heat shrink tube is pulled. The pulling speed of the second motor 2-4 and the sixth motor 7-4 is automatically matched with the pulling speed of the first motor 1-3 through the first sensor 1-11 to detect the position of the second swing rod 1-8. The pulling speed of the first motor 1-3 is adjusted and then pulled at a constant speed.

[0085] 2) Automatic detection of foreign matter in heat shrink tubes: The principle of judging foreign matter in heat shrink tubes is that the thickness of heat shrink tubes may have a certain tolerance variation under normal circumstances. When the thickness variation is gradual and within the normal tolerance range, it is considered normal. If the thickness suddenly rises and falls, and the variation range exceeds a certain proportional value, it is considered abnormal, and it is determined that there is foreign matter in the heat shrink tube. In this device, when there is foreign matter in the heat shrink tube, the thickness will change suddenly, which will cause the third driven roller assembly 2-10 to move up, thereby driving the detection plate 2-9 on the sliding base plate 2-13 to move up, and the pre-compression stroke of the displacement sensor 2-7 will become smaller, thereby detecting the change in displacement. At this time, after determining that there is foreign matter in the heat shrink tube, the second motor 2-4 and the sixth motor 7-4 stop rotating and pulling.

[0086] 3) Sealing the foreign body section of the heat shrink tube: The second cylinder 3-1 moves the second bottom plate 3-2 forward, and places the heat shrink tube 10 between the lower heat sealing head assembly 3-14 and the upper heat sealing head assembly 3-15. The fourth cylinder 3-9 drives the upper heat sealing head assembly 3-15 downward, and the fifth cylinder 3-12 drives the lower heat sealing head assembly 3-14 upward, thereby heating the heat shrink tube 10 for a few seconds. Then, the fourth cylinder 3-9 drives the heat sealing head assembly 3-15 back to its original position, and the fifth cylinder 3-12 drives the lower heat sealing head assembly 3-14 back to its original position. The second cylinder 3-1 moves the second bottom plate 3-2 backward, and the third cylinder 3-6 drives the cold pressing top plate 3-5 downward to cold press the heating section for a few seconds. The third cylinder 3-6 drives the cold pressing top plate 3-5 back to its original position, completing the first sealing of the heat shrink tube 10. Then, the second motor 2 - 4 and the sixth motor 7 - 4 rotate again, pull the heat shrink tube 10 for a distance and then stop, repeating the previous tube sealing action to seal the impurities between the two sealing sections.

[0087] 4) Automatically cut off the foreign body section of the heat shrink tube: The second motor 2-4 and the sixth motor 7-4 rotate to pull the heat shrink tube 10, and place the rear end of the first sealing section of the heat shrink tube 10 at the tube cutting position, which is specifically the interval between the first movable bottom plate 5-3-1 and the second movable bottom plate 5-3-2. The ninth cylinder 5-3-3 drives the first movable bottom plate 5-3-1 to move upward, and the tenth cylinder 5-3-4 drives the second movable bottom plate 5-3-2 to move upward. The seventh cylinder 5-2-9 drives the first pressing plate 5-2-10 and the vacuum suction cup 5-2-11 to move downward at the same time. The first pressing plate 5-2-10 fixes and presses the heat shrink tube 10 to ensure that it will not move around when cutting the tube, and the vacuum suction cup 5-2-11 sucks the heat shrink tube 10. The eleventh cylinder 5-4-1 drives the first blade 5-4-4 to move back and forth to cut the heat shrink tube 10. After the heat shrink tube 10 is cut, the seventh cylinder 5-2-9 retracts to drive the first pressure cutting plate 5-2-10 and the vacuum suction cup 5-2-11 to move upward, and the vacuum suction cup 5-2-11 will suck the heat shrink tube 10 and move it upward. The fifth motor 5-2-1 drives the second suction tube base plate 5-2-8 to move horizontally through the second driving gear assembly 5-2-2 and the rack 5-2-4, so that the vacuum suction cup 5-2-11 will drive the heat shrink tube 10 to move horizontally for a distance. At the same time, the second motor 2-4 rotates and synchronously pulls a section of the heat shrink tube. When the second pressure cutting plate 5-2-13 is located above the tube cutting position, the fifth motor 5-2-1 and the second motor 2-4 stop rotating. The eighth cylinder 5-2-14 drives the second pressure cutting plate 5-2-13 to move downward to press the heat shrink tube 10, and the eleventh cylinder 5-4-1 drives the first blade 5-4-4 to move back and forth to cut the heat shrink tube 10. The eighth cylinder 5-2-14 drives the second cutting plate 5-2-13 to move upward. The fourth motor 5-1-4 on the linear module mechanism 5-1 drives the tube pressing and sucking mechanism 5-2 to move backward, the vacuum suction cup 5-2-11 releases the suction force, and the sheared heat shrink tube falls onto the blanking plate assembly 5-5 and slides out of the equipment.

[0088] 5) Use adhesive tape to automatically bond two heat shrink tubes: the first downward pressure glue head 6-3-11 clamps the adhesive tape 6-3-3, and the fourteenth cylinder 6-3-5 pushes the glue-discharging substrate 6-3-6 to move to the left end, thereby pulling out the adhesive tape 6-3-3. Then the sixteenth cylinder 6-3-17 drives the second downward pressure glue head 6-3-18, the upper pressure glue head 6-3-19 clamps the adhesive tape head, and the fifteenth cylinder 6-3-9 drives the first downward pressure glue head 6-3-11 to move downward, thereby loosening the adhesive tape, and the fourteenth cylinder 6-3-5 pushes the glue-discharging substrate 6-3-6 back to the right end;

[0089] The fifteenth cylinder 6-3-9 drives the first downward pressure rubber head 6-3-11 to move upward and clamp the adhesive paper 6-3-3 again. The linear module mechanism 5-1 drives the adhesive paper suction mechanism 6-1 to move forward through the translation substrate 5-1-8. The vacuum suction plate 6-1-2 moves above the adhesive paper 6-3-3. The twelfth cylinder 6-1-3 drives the vacuum suction plate 6-1-2 to move downward, and the vacuum suction plate 6-1-2 sucks the adhesive paper 6-3-3.

[0090] The thirteenth cylinder 6-2-1 drives the second blade 6-2-8 to move back and forth, thereby cutting the adhesive tape 6-3-3. The sixteenth cylinder 6-3-17 drives the second downward pressure adhesive head 6-3-18, and the upward pressure adhesive head 6-3-19 releases the adhesive tape head. The twelfth cylinder 6-1-3 drives the vacuum suction plate 6-1-2 to move upward, and the vacuum suction plate 6-1-2 sucks away the cut adhesive tape 6-3-3.

[0091] The linear module mechanism 5-1 drives the adhesive paper suction mechanism 6-1 to move backward by translating the base plate 5-1-8, so that the vacuum suction plate 6-1-2 is located above the heat shrink tube 10. The twelfth cylinder 6-1-3 drives the vacuum suction plate 6-1-2 to move downward, sticks the adhesive paper to the heat shrink tube, and connects the two ends of the heat shrink tube together. The vacuum suction plate 6-1-2 releases the suction force, and the twelfth cylinder 6-1-3 drives the vacuum suction plate 6-1-2 to move upward.

[0092] 6) Flip the heat shrink tube and use adhesive tape to double-sidedly bond it: the ninth cylinder 5-3-3 drives the first movable bottom plate 5-3-1 to move downward, and the tenth cylinder 5-3-4 drives the second movable bottom plate 5-3-2 to move downward. The push rod of the sixth cylinder 4-13 moves downward, and under the action of the spring 4-9, the upper pressure plate 4-8 moves downward to clamp the heat shrink tube 10. The third motor 4-1 drives the flip plate 4-6 to rotate 180° through the first active gear assembly 4-3 and the driven gear 4-4, thereby driving the heat shrink tube to flip. Repeat the previous adhesive tape sticking action. When the adhesive tape is finished, the third motor 4-1 drives the flip plate 4-6 to rotate back to its original position through the first active gear assembly 4-3 and the driven gear 4-4. The push rod of the sixth cylinder 4-13 moves upward, driving the lifting plate 4-12 to move upward, thereby driving the upper pressure plate 4-8 to move upward and releasing the heat shrink tube 10. The processed heat shrink tube can finally fall into the blanking frame, or directly connect to the subsequent process flow.

[0093] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
