Description

Technical Field

[0001] The invention relates to the technical field of plastic chemical storage tank molding, in particular to a flash trimming device for a plastic chemical storage tank after molding. Background Art

[0002] Plastic chemical storage tanks are a type of plastic container specially designed for storing chemicals. They are usually made of materials with excellent corrosion resistance, such as polyethylene, polypropylene, etc., and can resist the erosion of a variety of chemicals. Compared with metal storage tanks, plastic storage tanks are lighter, easier to carry and install, and have relatively low manufacturing costs. They also have a long service life and low maintenance costs. There are a variety of specifications and capacities to choose from to meet the storage needs of different chemicals and are widely used in various industries.

[0003] During the processing and molding of plastic storage tanks, if the mold parting surface is worn or there are foreign objects, gaps will exist after the mold is closed, or the joints such as the mold insert gaps, the sliding parts of the slider, and the holes of the ejector rod are not tight, which can easily cause overflow, resulting in flash on the edge of the molded plastic storage tank. In order to ensure the aesthetics and subsequent use of the plastic storage tank, it is necessary to use relevant flash trimming devices to trim and remove the flash.

[0004] In the process of trimming and removing the flash of plastic storage tanks, the flash trimming device in the prior art usually directly adopts the relevant cutting mechanism or grinding mechanism to cut or grind it. Since there is no relevant mechanism for automatically recovering the flash plastic debris inside the device, the removed flash plastic debris will splash everywhere, affecting the cleanliness of the device and its surrounding environment, and it will also make it impossible to effectively recycle the trimmed plastic debris, resulting in a waste of this part of the plastic raw materials, increasing the production cost of the enterprise, and failing to meet people's usage needs.

[0018] 1. In this invention, through the recovery mechanism, when the trimming mechanism trims and removes the flash of the plastic can, the two vacuum heads can automatically suck and clean the trimmed flash debris, which is convenient for the subsequent recycling and reuse of this part of the collected plastic flash debris, so as to achieve the effect of saving the use of plastic raw materials, reduce the production cost of the enterprise, and enable the device to meet people's usage needs.

[0019] 2. In this invention, during the process of trimming and removing the flash on the inner wall of the plastic can with the help of a trimming mechanism, some plastic debris will inevitably be temporarily stored inside the plastic can. After the trimming mechanism trims the flash on the inner wall of the plastic can, the multiple components of the trimming mechanism cooperate with each other to drive the rectangular plate and the corresponding soft pad to clamp and fix the outer wall of the plastic can in the center position. At this time, with the help of the rotation of the second drive motor, the clamped plastic can can be driven to flip 180 degrees, so that the plastic debris temporarily stored inside the plastic can can be automatically discharged downward, which is convenient for the subsequent use of the plastic can.

[0020] 3. In this invention, after the flash of the plastic can is trimmed by the trimming mechanism, a small amount of debris will inevitably adhere to its surface. In order to avoid affecting the subsequent appearance quality inspection of the flash trimmed part, the two rectangular plates can be controlled to rotate and adjust, driving the cleaning pad on the outer wall of one side to rotate to a position close to the trimmed flash position, and repeating the steps of the trimming mechanism to remove the flash, driving the cleaning pad to rotate or move and adjust, so that the cleaning pad can automatically clean and remove these debris.

[0021] 4. In the present invention, the appearance of the trimmed plastic cans can be automatically identified and inspected by a preset visual inspection device to ensure that the appearance quality of the plastic cans is not affected after the trimming.

A third driving device is also preset inside the second rotating plate 8, and the output end of the third driving device is connected to the rotating part of the bottom end of the second rotating plate 8, so that the second rotating plate 8 can be driven to rotate and adjust at the top end of the mounting plate 38; a third linear motor is preset inside the third slide groove 33, and the third linear motor can drive the third slider 37 to move up and down inside the third slide groove 33, and drive the mounting block 9, the pressure plate 10 and the rubber block 35 to move up and down synchronously; the connecting end 34 can be connected to an external preset inflation device, so that the circular hole 36 can discharge air downward.

[0046] In the present invention, when the user uses the device, Figure 1As shown, a loading robot and an unloading robot are preset at the front of the device and near the second rotating plate 8 respectively. With the help of the loading robot, the plastic can that needs to be trimmed is placed on the top of the first placement plate 2 on the front of the device. After it is clamped and fixed with the help of two clamping plates 13, the rotating frame 11 is controlled to rotate 90 degrees clockwise so that the second placement plate 2 is rotated to the front. The loading robot then places the next plastic can on the top of the second placement plate 2, and the subsequent two second placement plates 2 continue to repeat the above steps. After the first placement plate 2 and the plastic can on its top are rotated to the bottom of the trimming mechanism, the first slider 16 is controlled to move downward and adjusted inside the first slide groove 15 according to the height of the plastic can, driving the two rectangular plates 7 of the trimming mechanism to move to both sides close to the top of the plastic can, and according to the plastic can height, the first slider 16 is controlled to move downward and adjusted inside the first slide groove 15 ... and The flash position on the top of the material tank needs to be trimmed, and the two second sliders 25 are controlled to move up and down and adjust inside the corresponding second slide groove 23, and the trimming knife 26 and the grinding roller 27 are driven to move to a height flush with the flash position of the plastic tank. Then, the second double-headed screw 24 is controlled to rotate, driving the two first moving seats 20 and the rectangular plate 7 to move in the direction of approaching, and driving the trimming knife 26 and the grinding roller 27 to move together until they contact the flash of the plastic tank, controlling the grinding roller 27 to rotate and synchronously controlling the second drive motor 19 to drive the rotating rod 6 to rotate and adjust together, driving the trimming knife 26 and the grinding roller 27 to rotate synchronously on the flash of the plastic tank, and removing and trimming the flash with the help of the cutting of the trimming knife 26 and the rotation of the grinding roller 27, so as to achieve the effect of automatically trimming the flash of the plastic tank.

[0047] After the positions of the trimming knife 26 and the grinding roller 27 are adjusted to the position close to the burr of the plastic jar, the third double-headed screw 28 can be synchronously controlled to rotate, driving the two second movable seats 31 and the dust collector 30 to move to the position close to the trimming knife 26 and the grinding roller 27, and controlling the telescopic ends of the two second electric telescopic rods 29 to drive the height of the two dust collector heads 30 to adjust, so that the two dust collector heads 30 are respectively moved downward to the position close to the burr of the plastic jar. When the trimming knife 26 and the grinding roller 27 trim and remove the burr of the plastic jar, the two dust collector heads 30 can automatically suck and clean the trimmed burr debris to avoid the burr debris from splashing everywhere, which is convenient for the subsequent recycling and reuse of this part of the collected plastic burr debris, so as to achieve the effect of saving the use of plastic raw materials.

[0048] At the same time, since the two rectangular plates 7 can be rotated and adjusted while driving the trimming knife 26 and the grinding roller 27 to rotate and adjust synchronously, when it is necessary to trim and remove the flash of the inner wall of the plastic jar mouth, the two rectangular plates 7 can be controlled to rotate 180 degrees together, driving the trimming knife 26 and the grinding roller 27 to rotate and adjust to a position away from each other, and then the first slider 16 can be controlled to drive the two rectangular plates 7 and other components to move upward for adjustment. If the height of the plastic jar is relatively high, the first rotating block 17 can be controlled to rotate upward inside the first slider 16 to drive the two rectangular plates 7 to adjust upward to a position higher than the plastic jar, and then the two first movable seats 2 0 and the rectangular plate 7 are moved and adjusted in the direction of approaching each other to ensure that the distance between the two rectangular plates 7 is smaller than the diameter of the plastic jar mouth. As the first slider 16 drives the two rectangular plates 7 to move downward or the first rotating block 17 is rotated and adjusted downward, the two adjusted rectangular plates 7 are driven to move downward to the inside of the plastic jar, and then the heights of the trimming knife 26 and the grinding roller 27 are adjusted according to the position of the burr on the inner wall of the plastic jar mouth. Finally, the two first movable seats 20 and the rectangular plate 7 are controlled to move in the direction of moving away from each other, driving the trimming knife 26 and the grinding roller 27 to contact the burr on the inner wall of the plastic jar mouth and trim and remove them, so as to achieve the effect of automatically trimming and removing the burr on the inner wall of the plastic jar mouth.

[0049] If the plastic jar is formed by injection molding, a vertical burr will be formed on part of the outer wall of the plastic jar. If the burr of the outer wall of such a plastic jar needs to be trimmed and removed, after the plastic jar is rotated to the bottom of the trimming mechanism, the first rotating block 17 is controlled to drive the rotating rod 6 and the two rectangular plates 7 to rotate upward 90 degrees to a horizontal state, and the telescopic ends of the two telescopic cylinders 3 are controlled to retract together, driving the two rectangular plates 7 to move to both sides of the plastic jar, and by controlling the placement plate 2 to rotate and adjust, the two vertical burrs on the outer wall of the plastic jar are driven to rotate to a position parallel to the two rectangular plates 7 respectively, and then the positions of the trimming knife 26 and the grinding roller 27 are controlled to move to positions corresponding to the burrs, and then the two rectangular plates 7 are controlled to move in a direction close to each other, driving the trimming knife 26 and the grinding roller 27 to move to abut against the burrs, so that at this time the trimming knife 26 and the grinding roller 27 can be adjusted up and down inside the first slide groove 15 with the help of the first slider 16, so that the vertical burrs on the outer wall of the plastic jar can be trimmed and removed, thereby improving the applicability of the trimming mechanism.

[0050] In the process of trimming and removing the flash of the inner wall of the plastic can with the help of the trimming mechanism, some plastic debris will inevitably be temporarily stored inside the plastic can. In order to avoid these plastic debris remaining inside the plastic can and affecting the subsequent use of the plastic can, after the trimming mechanism trims the flash of the inner wall of the plastic can, the two rectangular plates 7 and other components are controlled to move outward from the inner wall of the plastic can and reset, and the trimming knife 26 and the grinding roller 27 are maintained in a state of being in a state of being far away from each other. At this time, the soft pads 21 on the outer walls of the two rectangular plates 7 are rotated to a close position, and the above-mentioned steps of trimming and removing the vertical flash of the outer wall of the plastic can are repeated, so that the two horizontal rectangular plates 7 are located on both sides of the plastic can, and the two rectangular plates 7 are controlled to move in a direction of approaching each other, driving the rectangular plates 7 and the corresponding soft pads 21 to clamp and fix the outer wall of the plastic can in the center position. At this time, with the help of the rotation of the second drive motor 19, the clamped plastic can can be driven to flip 180 degrees, so that the plastic debris temporarily stored inside the plastic can can be automatically discharged downward, which is convenient for the subsequent use of the plastic can.

[0051] After the burrs of the plastic can are trimmed by the trimming mechanism, a small amount of debris will inevitably be attached to its surface. In order to avoid affecting the appearance quality inspection of the subsequent burr trimming parts, the two rectangular plates 7 can be controlled to rotate and adjust, driving the cleaning pad 22 on the outer wall of one side to rotate to a position close to the trimmed burr position, repeating the steps of removing the burrs with the trimming knife 26 and the grinding roller 27, driving the cleaning pad 22 to rotate or move and adjust, so that the cleaning pad 22 can automatically clean and remove these debris.

[0052] After the trimming, the plastic cans can be moved to a position close to the second rotating plate 8 as the rotating frame 11 rotates clockwise. A relevant visual inspection device is preset near the second rotating plate 8, which can control the corresponding placement plate 2 to drive the plastic cans to rotate slowly, so that the visual inspection device can automatically identify and inspect the appearance of the plastic cans after the flash trimming, to ensure that the appearance quality of the plastic cans is not affected after the trimming. If some of the trimmed plastic cans fail the appearance inspection, the third slider 37 can be directly controlled to move downward inside the third slide groove 33 to drive the pressing plate 10 to squeeze the unqualified plastic cans, and after squeezing them into a flat shape, the clamping mechanism is controlled to contact the clamping limit of the plastic cans, and then the second rotating plate 8 is controlled to rotate counterclockwise, driving the pressing plate 10 to push the flattened plastic cans down from the top of the placement plate 2, so as to automatically process the plastic cans with unqualified appearance, and by flattening them, it is also convenient to reduce the volume of such unqualified plastic cans, making them convenient for recycling and reuse, thereby avoiding waste of such unqualified plastic cans.

[0053] At the same time, for plastic cans that have passed the appearance inspection, the pressure plate 10 of the testing mechanism can also be used to squeeze some of the plastic cans downward under certain pressure conditions to achieve the effect of random inspection of the strength performance of the plastic cans that have passed the appearance inspection, ensuring that the strength of the plastic cans after the flash trimming treatment is not affected; if the strength performance test of the plastic cans fails, the above steps can be repeated, and the plastic cans can be directly flattened with the help of the pressure plate 10 to facilitate their recycling.

[0054] The jar is then pressed against the bottom edge of the plastic jar and the jar is then pressed against the bottom edge of the plastic jar.

[0055] After the plastic cans have passed the appearance, strength and sealing tests, the clamping mechanism is controlled to contact and clamp them, and the unloading robot preset near the second rotating plate 8 is used to slowly and flexibly clamp and unload them. As the rotating frame 11 continues to rotate, the placement plate 2 is driven back to the front of the device, and the loading robot continues to place subsequent plastic cans on the top of the placement plate 2 for related flash trimming and testing work, thereby achieving the effect of continuous processing of large quantities of plastic cans.

[0056] If the device is in use, the rotating frame 11 fails, resulting in the inability to continue to drive the multiple placement plates 2 and the plastic cans on top to rotate in turn to the bottom of the trimming mechanism and the testing mechanism to perform related flash trimming and testing work, at this time, after the loading robot places the plastic can on the top of the placement plate 2 on the front of the device, the two rectangular plates 7 are controlled to rotate 180 degrees together, driving the two rectangular plates 7 with the side of the cushion 21 installed to rotate to a close position, and then the telescopic ends of the two first electric telescopic rods 18 are controlled to extend together, driving the rotating rod 6 and the two rectangular plates 7 and other components to move together to the top of the placement plate 2 on the front of the device, and as the first slider 16 moves downward inside the first slide groove 15, the two rectangular plates 7 are driven to move to both sides of the plastic can, and with the help of the two rectangular The plates 7 move in the direction of approaching each other, clamping and fixing the plastic cans, and then controlling the first slider 16 to move upward inside the first slide 15, which can drive the plastic cans placed on the top of the placement plate 2 on the front of the device to move upward together, and controlling the telescopic ends of the two first electric telescopic rods 18 to retract and return to their original positions together, driving the clamped and fixed plastic cans to be transferred to the top of the placement plate 2 just below the trimming mechanism. As the first slider 16 moves downward inside the first slide 15, the transferred plastic cans can be placed on the top of the placement plate 2 below, and the plastic cans can be clamped and fixed with the help of the corresponding clamping mechanism, so that the trimming mechanism can continue to trim the burrs of the plastic cans, avoiding damage to the rotating frame 11, which may cause the problem of being unable to drive the plastic cans for continuous processing, and improving the applicability of the trimming mechanism.

[0057] At the same time, if it is necessary to continue to transfer the plastic can after the flash trimming to be placed directly under the testing mechanism and carry out relevant testing work, after the flash trimming of the plastic can, the two rectangular plates 7 and the soft pad 21 can be used to clamp the plastic can again, and then the second rotating plate 8 is controlled to drive the pressure plate 10 and other components to rotate 180 degrees, driving the pressure plate 10 to rotate to a position away from the base 1, and then the first slider 16 can be controlled to drive the plastic can to be taken out from the top of the placement plate 2 below, and the first rotating plate 5 is controlled to drive the trimming mechanism and the clamped plastic can to rotate in the direction close to the second rotating plate 8, and then the telescopic ends of the two first electric telescopic rods 18 are controlled to extend together, driving the clamped plastic can to move to the top of the placement plate 2 close to the second rotating plate 8. As the first slider 16 moves downward, the plastic can can be placed on the top of the placement plate 2 close to the second rotating plate 8, and finally the rotating plate 8 is controlled to drive the pressure plate 10 and other components to rotate and reset, so that it can continue to carry out relevant testing work on the plastic can.
