Description

Technical Field

[0001] This utility model belongs to the technical field of supporting facilities for hollow plastic container blow molding machines, specifically relating to an automatic deflash removal device with a stacking barrel bottom process deflash piercing and suspension function. Background Technology

[0002] The stacking drums mentioned above are also called palletizing drums, and the process flash mentioned above is the process waste or overflow burr. It is formed by excess melt escaping during the high-pressure blowing and cooling of hollow plastic melt, because the parting surface of the symmetrical two halves of the mold cannot be absolutely sealed. Factors that are causally related to process flash include, but are not limited to, melt temperature, blow molding pressure, clamping force, melt viscosity, mold wear, etc. Since the flash on the bottom of stacking bins is excess plastic overflowing from the mold parting line (i.e., between the mold surfaces), removing it offers the following advantages: It creates a flat, relatively smooth bottom surface; a flat bottom is essential for successful stacking; otherwise, even a single bin placed on the ground will tilt, wobble, and become unstable, hindering transportation and storage; it improves product safety, as sharp edges can easily injure workers' hands or bodies during handling; it optimizes the product's appearance, resulting in a rough, unrefined look, potentially relegating it to semi-finished or even waste status; and the flash material can be recycled, reflecting the principles of a resource-saving and energy-efficient circular economy. Therefore, removing flash from the bottom of stacking bins is a necessary, not optional, step.

[0003] Chinese patent literature contains numerous technical information related to removing flash from stacking barrels. For example, CN108748954A provides an "adjustable flash removal device for blow molding machines," and CN116141641A describes an "automatic flash clamping device for blow-molded stacking barrels." Foreign patents also contain technical information related to flash in stacking barrel processes. For instance, German patent DE102008060625A discloses a "blow molding die for manufacturing plastic containers and a method for operating such a die," which addresses the root cause of flash formation. Japanese patent JP2007069494A discloses a "method and apparatus for removing flash from molded articles," which solves the flash problem through processes such as thermal softening, low-temperature finishing, and real-time adjustment. US patent US2002016141A1 discloses a "method and apparatus for cutting flash from plastic containers," which involves rotary cutting of flash from blow-molded barrels, bottles, etc.

[0004] Since the aforementioned domestic and foreign patents either address the removal of burrs on the upper part of containers such as stacking barrels, such as the handle area, or describe the suppression and removal of burrs in a too broad and unspecific way, they do not provide any technical inspiration for the process of removing burrs from the bottom of stacking barrels.

[0005] The technical information on flash removal at the bottom of stacked buckets is described in detail in paragraphs 0003 to 0006 of the background technology section of the "Handle Flash Removal Device for Stacking Bucket Process" recommended by CN102285101A, with illustrations. While this type of stacking drum bottom flash removal device can remove the process flash from the bottom of the drum, it has the following technical problems: When the bottom-tapping knife working cylinder is working, that is, when the bottom-tapping knife connecting rod drives the second bottom-tapping knife to move towards the direction of the first bottom-tapping knife to remove the process flash remaining in the center of the bottom of the drum, the stacking drum has just completed the blow-forming process at the blow-forming station. Therefore, the stacking drum body and its process flash are not fully cooled and solidified, and are still in a somewhat viscous state. Furthermore, since the process flash at the bottom of the drum is removed with the bottom of the stacking drum facing upwards, and since there is no temporary support on the side facing the process flash at the bottom of the drum, when the bottom-tapping knife strikes and removes the process flash from the bottom of the drum, there is a high probability that the process flash at the bottom of the drum that has not been removed from the bottom wall will overturn and immediately and stubbornly adhere to the bottom wall of the drum. Once the process flash adheres to the bottom wall of the drum, the entire stacking drum will be scrapped. Another scenario involves attempting to separate the flash from the bottom wall of the bucket by striking it with a bottom-beating tool. Due to the aforementioned factors—the bucket body and the flash are still in a relatively softened, viscous state—a flange remains at the point where the flash separates from the bottom wall. This flange, after sufficient cooling, becomes a burr, which can affect the appearance or, in severe cases, render the stacked buckets defective. Typically, the former, due to its severity, necessitates scrapping, while the latter, being less severe, is removed by workers at a separate station, such as the inspection station, using tools such as files or shavings. The former impacts costs and wastes energy, while the latter is detrimental to conserving valuable labor resources, and the quality of secondary processing is difficult to guarantee. Furthermore, improper operation can even damage the bottom of the bucket. Utility Model Content

[0006] The objective of this invention is to provide an automatic flash removal device with a flash piercing and suspension function for stacked buckets. This device helps to pre-pierce the flash before expelling it to the bottom of the bucket, and then suspend the flash after separating it from the bottom and removing it from the bucket body. The flash is then removed while pierced and suspended, thus preventing the flash from adhering to the bottom of the bucket.

[0007] The present invention achieves its objective by providing an automatic deflash removal device with a function of piercing and suspending the burrs at the bottom of stacked buckets. This device includes a left support plate and a right support plate, which correspond to each other and, in use, are pushed apart or closed together by a support plate opening and closing mechanism. It also includes a bucket bottom deflash removal mechanism, which is located at the upper front end of either the left or right support plate. The device is characterized by further including a bucket bottom deflash piercing and suspension removal mechanism, which, in conjunction with the bucket bottom... The flash removal mechanism is positioned face-to-face on the upper front end of the right or left back plate. Before the flash removal mechanism strikes the bottom edge of the stacked bucket, the flash removal mechanism pierces the bottom edge in the thickness direction. After the flash removal mechanism strikes the bottom edge and separates it from the bottom cavity of the stacked bucket, and after the stacked bucket with the flash removed is removed, the bottom edge is suspended in the air and is driven away by the flash removal mechanism and falls naturally downwards.

[0008] In a specific embodiment of this utility model, the bucket bottom burr removal mechanism is located at the upper front end of the right back plate, while the bucket bottom burr piercing and suspension removal mechanism is located at the upper front end of the left back plate and maintains a face-to-face correspondence with the bucket bottom burr removal mechanism.

[0009] In another specific embodiment of this utility model, the barrel bottom burr removal mechanism includes a right burr driving cylinder, a right burr, and a pair of right burr guide rods. The right burr driving cylinder is fixed in a horizontal position to the upper right side of the front end of the right back plate, and the pair of right burr driving cylinder columns of the right burr driving cylinder extend to the left side of the right back plate. The right burr is located on the left side of the right back plate, and the right side of the middle part of the right burr in the length direction is fixed to the end of the right burr driving cylinder column. The pair of right burr guide rods are horizontally parallel to each other and correspond to the front and rear sides of the right burr driving cylinder, respectively. Each pair of right burr guide rods slides with the right back plate through a right burr guide rod sleeve, and the left ends of the pair of right burr guide rods are fixed to the right burr at positions corresponding to the front and rear sides of the right burr driving cylinder column, respectively. A first through hole for the burr head and a second through hole for the burr head are provided on the right burr at a position corresponding to the barrel bottom burr piercing and suspension removal mechanism.

[0010] In another specific embodiment of this utility model, the right-hand cutting tool driving cylinder is a pneumatic cylinder, a hydraulic cylinder, or an electric push cylinder; a right-hand cutting tool guide sleeve mating hole is provided on the right back plate at the position corresponding to the right-hand cutting tool guide sleeve, extending from the right side of the right back plate to the left side, and the right-hand cutting tool guide sleeve is fixed to the right back plate at the position corresponding to the right-hand cutting tool guide sleeve mating hole.

[0011] In another specific embodiment of this utility model, the barrel bottom burr piercing and suspension removal mechanism includes a left-hand strike driving cylinder, a left strike, a pair of left-hand strike guide rods, and a barrel bottom burr piercing and suspension device. The left-hand strike driving cylinder is fixed in a horizontal position to the upper left side of the front end of the left support plate, and the left-hand strike driving cylinder column of the left-hand strike driving cylinder extends to the right side of the left support plate. The left strike is located on the right side of the left support plate, and the left side of the middle part of the left strike in the length direction is fixed to the end of the left-hand strike driving cylinder column and corresponds to the right strike. The pair of left-hand strike guide rods are laterally parallel to each other and correspond to the front and rear sides of the left-hand strike driving cylinder, respectively. Each of the pair of left-hand strike guide rods slides with the left support plate through a left-hand strike guide rod sleeve. The right ends of the left-hand guide rods are fixed to the left-hand blade at positions corresponding to the front and rear sides of the left-hand blade driving cylinder, respectively. The barrel bottom piercing suspension device includes a first piercing rod and a second piercing rod. The first piercing rod corresponds to the rear side of the left-hand blade driving cylinder, while the second piercing rod corresponds to the front side of the left-hand blade driving cylinder. The left end of the first piercing rod is fixed to the right side of the left backing plate, while the right end engages or disengages with the first sliding hole of the piercing rod and the first through hole of the piercing rod head, which are opened on the left-hand blade and correspond to the first piercing rod. The left end of the second piercing rod is fixed to the right side of the left backing plate, while the right end engages or disengages with the second sliding hole of the piercing rod and the second through hole of the piercing rod head, which are opened on the left-hand blade and correspond to the second piercing rod.

[0012] In another specific embodiment of this utility model, a first spiked rod piercing cone is formed at the right end of the first spiked rod, and a second spiked rod piercing cone is formed at the right end of the second spiked rod.

[0013] In a further specific embodiment of this utility model, the left cutting tool driving cylinder is a pneumatic cylinder, a hydraulic cylinder, or an electric push cylinder; a left cutting tool guide rod guide sleeve mating hole is provided on the left back plate at the position corresponding to the left cutting tool guide rod guide sleeve, extending from the left side of the left back plate to the right side, and the left cutting tool guide rod guide sleeve is fixed to the left back plate at the position corresponding to the left cutting tool guide rod guide sleeve mating hole.

[0014] The technical solution provided by this utility model allows for the pre-piercing and suspension removal mechanism to pierce the thickness direction of the burr before the burr, which serves as the process burr, is instantly expelled from the bottom of the bucket by the burr-piercing and suspension removal mechanism. After the burr-piercing and suspension removal mechanism strikes the burr and separates it from the bottom of the stacked bucket, the suspended burr is expelled by the burr-piercing and suspension removal mechanism and falls naturally downwards. This prevents the burr that has been knocked off the bottom of the bucket by the burr-piercing and suspension removal mechanism from overturning and adhering to the bottom of the bucket, ensuring the quality of the bucket and preventing the stacked bucket from being scrapped due to burr removal.

[0017] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are based on the current direction. Figure 1 The location and state of the object are taken into account, and therefore should not be construed as a special limitation on the technical solution provided by this utility model.

[0018] Please see Figure 1 It shows a left backing plate 1 (also called "left wall plate" or "left horizontal plate", hereinafter the same) and a right backing plate 2 (also called "right wall plate" or "right horizontal plate", hereinafter the same). The left backing plate 1 and the right backing plate 2 correspond to each other (left and right correspond) and in use, they are pushed apart or closed together by the action of the backing plate opening and closing drive mechanism; it also shows a barrel bottom sprue trimming mechanism 3, which is set at the upper front end of the aforementioned right backing plate 2.

[0019] The key technical points of the technical solution provided by this utility model are as follows: It also includes a barrel bottom burr piercing and suspension removal mechanism 4. The barrel bottom burr piercing and suspension removal mechanism 4 is set at the upper front end of the aforementioned left back plate 1 in a state of facing the aforementioned barrel bottom burr cutting mechanism 3. Before the aforementioned barrel bottom burr cutting mechanism 3 strikes the barrel bottom burr 51 of the stacked barrel 5, the aforementioned barrel bottom burr piercing and suspension removal mechanism 4 pre-pierces the barrel bottom burr 51 in the thickness direction. After the barrel bottom burr cutting mechanism 3 strikes the barrel bottom burr 51 and separates the barrel bottom burr 51 from the bottom wall of the stacked barrel 5, and after the stacked barrel 5 with the separated barrel bottom burr 51 is removed, the aforementioned barrel bottom burr 51 is in a suspended state and is driven away by the barrel bottom burr piercing and suspension removal mechanism 4 and falls down naturally.

[0020] The applicant should note that if the aforementioned barrel bottom burr removal mechanism 3 is set at the upper front end of the aforementioned left back plate 1, and the aforementioned barrel bottom burr piercing and suspension removal mechanism 4 is set at the upper front end of the aforementioned right back plate 2 and maintains a face-to-face correspondence with the barrel bottom burr removal mechanism 3, then it should be considered equivalent to the aforementioned arrangement.

The aforementioned barrel bottom burr piercing and suspension removal mechanism 4 is located above the aforementioned lower left retaining plate 11, and the aforementioned barrel bottom burr removal mechanism 3 is located above the aforementioned lower right retaining plate 21.

[0022] Depend on Figure 1 As shown in the diagram, the stacking bin 5 is positioned with its bottom facing upwards during the flash removal process, which is exactly 180° different from its normal placement. More specifically, Figure 1 The upper part of the barrel shown is exactly the lower part (bottom) of the barrel, and Figure 1 The lower part of the barrel shown is precisely the upper part of the barrel. Based on this, the lower and upper parts of the barrel referred to in the applicant's following description are based on the above concept. Furthermore, for ease of expression, the applicant will... Figure 1 The process flash shown in the diagram is defined as the bottom flash 51 of the barrel.

[0023] The aforementioned barrel bottom trimming mechanism 3 includes a right trimming drive cylinder 31, a right trimming knife 32, and a pair of right trimming knife guide rods 33. The right trimming drive cylinder 31 is fixed in a horizontal position to the upper right side of the front end of the aforementioned right backing plate 2, and the pair of right trimming drive cylinder pins 311 of the right trimming drive cylinder 31 extend to the left side of the right backing plate 2. The right trimming knife 32 is located on the left side of the right backing plate 2, and the right side of the middle part of the right trimming knife 32 in the length direction is fixed to the end of the right trimming drive cylinder pin 311. The pair of right trimming knife guide rods 33 are horizontally parallel to each other. The states of the lines correspond to the front and rear sides of the aforementioned right striking knife driving cylinder 31, and each of the pair of right striking knife guide rods 33 slides with the right backing plate 2 through the right striking knife guide rod sleeve 331. The left ends of the pair of right striking knife guide rods 33 are fixed to the aforementioned right striking knife 32 at positions corresponding to the front and rear sides of the aforementioned right striking knife driving cylinder column 311. A first through hole 321 and a second through hole 322 for the head of the piercing rod are provided on the aforementioned right striking knife 32 at a position corresponding to the aforementioned barrel bottom burr piercing suspension removal mechanism 4.

[0024] In this embodiment, the aforementioned right-hand cutting drive cylinder 31 is a pneumatic cylinder, but it can also be a hydraulic cylinder or an electric push cylinder; a right-hand cutting guide rod sleeve mating hole is provided on the aforementioned right back plate 2 at the position corresponding to the aforementioned right-hand cutting guide rod sleeve 331, extending from the right side of the right back plate 2 to the left side, and the right-hand cutting guide rod sleeve 331 is fixed to the right back plate 2 by screws at the position corresponding to the right-hand cutting guide rod sleeve mating hole.

[0025] See you later Figure 1 The aforementioned barrel bottom burr piercing and suspension removal mechanism 4 includes a left-hand strike driving cylinder 41, a left-hand strike 42, a pair of left-hand strike guide rods 43, and a barrel bottom burr piercing and suspension device 44. The left-hand strike driving cylinder 41 is fixed in a horizontal position to the upper left side of the front end of the aforementioned left back plate 1, and the left-hand strike driving cylinder column 411 of the left-hand strike driving cylinder 41 extends to the right side of the left back plate 1. The left-hand strike 42 is located on the right side of the left back plate 1, and the left side of the middle part of the left-hand strike 42 in the length direction is fixed to the end of the left-hand strike driving cylinder column 411 and corresponds to the aforementioned right-hand strike 32. The pair of left-hand strike guide rods 43 are horizontally parallel to each other and correspond to the front and rear sides of the aforementioned left-hand strike driving cylinder 41, and each of the pair of left-hand strike guide rods 43 slides with the left back plate 1 through a left-hand strike guide rod sleeve 431. The right ends of the pair of left-hand strike guide rods 43 correspond to the front and rear sides of the aforementioned left-hand strike driving cylinder 41, respectively. The front and rear positions of the aforementioned left-hand striker driving cylinder 411 are fixed to the aforementioned left-hand striker 42. The barrel bottom piercing suspension device 44 includes a first spike rod 441 and a second spike rod 442. The first spike rod 441 corresponds to the rear side of the aforementioned left-hand striker driving cylinder 411, while the second spike rod 442 corresponds to the front side of the left-hand striker driving cylinder 411. The left end of the first spike rod 441 is fixed to the right side of the left backing plate 1, while the right end engages or disengages with the spike rod first sliding hole 422 and the spike rod head first through hole 321 on the left-hand striker 42, which corresponds to the first spike rod 441. The left end of the second spike rod 442 is fixed to the right side of the left backing plate 1, while the right end engages or disengages with the spike rod second sliding hole 423 and the spike rod head second through hole 322 on the left-hand striker 42, which corresponds to the second spike rod 442.

[0026] Depend on Figure 1 As shown, a first spike piercing cone 4411 is formed at the right end of the first spike 441, and a second spike piercing cone 4421 is formed at the right end of the second spike 442.

[0027] In this embodiment, the aforementioned left-hand cutting tool driving cylinder 41 is a pneumatic cylinder, but a hydraulic cylinder or an electric push cylinder can also be used; a left-hand cutting tool guide sleeve mating hole is provided on the aforementioned left back plate 1 at the position corresponding to the aforementioned left-hand cutting tool guide sleeve 431, extending from the left side of the left back plate 1 to the right side, and the left-hand cutting tool guide sleeve 431 is fixed to the left back plate 1 at the position corresponding to the left-hand cutting tool guide sleeve mating hole.

[0028] Preferably, a downward-sloping left-hand blade inclined surface 421 is formed on the right side of the aforementioned left-hand blade 42 along its length, for piercing the suspended barrel bottom edge and abutting against one side. This inclined surface 421 makes the longitudinal cross-sectional shape of the left-hand blade 42 trapezoidal, while the longitudinal cross-sectional shape of the aforementioned right-hand blade 32 is rectangular. Alternatively, a right-hand blade edge can be formed on the lower left side of the right-hand blade 32 along its length.

[0029] See you later Figure 1 A lower left side fitting cavity 111 is formed on the right side of the lower left side of the stacking barrel body, and a higher left side fitting cavity 121 is formed on the right side of the upper left side of the stacking barrel body; a lower right side fitting cavity 211 is formed on the left side of the lower right side of the stacking barrel body, and a higher right side fitting cavity 221 is formed on the left side of the upper right side of the stacking barrel body; the lower left and right side fitting cavities 111 and 211, the upper left side fitting cavity 121, and the upper right side fitting cavity 221 are all the same in shape and size. Of course, if the shape of the stacking barrel 5 changes, the shapes of the aforementioned mating cavities 111 and 211 on the lower left and right sides of the stacking barrel body, the mating cavity 121 on the upper left side of the stacking barrel body, and the mating cavity 221 on the upper right side of the stacking barrel body will also change accordingly, so that they are closely related to the shape and size of the stacking barrel 5.

[0030] Since, based on common knowledge, the method of connecting the left back plate 1 and the right back plate 2 to the relevant components of the aforementioned back plate opening and closing drive mechanism through the left back plate fixing hole 13 and the right back plate fixing hole 23 respectively in the use state is a known technology and can also refer to the patent mentioned by the applicant in the background technology section above, the applicant will not elaborate further.

[0031] Under the operation of the backplate opening and closing drive mechanism, the left backplate 1 and right backplate 2 are pushed apart. The robot arm picks up the stacked bucket 5, which has been blown into shape at the blow-forming station, and feeds it between the left backplate 1 and right backplate 2 while it is rotated 180°. Immediately afterwards, the backplate opening and closing drive mechanism causes the left backplate 1 and right backplate 2 to close and hold the stacked bucket 5. That is, the aforementioned left and right holding plates 11 and 21 at the bottom of the bucket and the left and right holding plates 12 and 22 at the top of the bucket hold (i.e., clamp) the stacked bucket, which is to be deburred at the bottom 51, and holds it in place by the aforementioned left and right holding plates 11 and 21 at the bottom of the bucket and the left and right holding plates 12 and 22 at the top of the bucket. Figure 1In the state shown, the bottom of the stacked bucket 5 faces upwards, and the corresponding bottom burr 51 also faces upwards. Since the bottom burr pierces the suspension device 44 and is fixed to the right side of the left backing plate 1, when the left backing plate 1 moves to the right, its first spike 441 and second spike 442 have already pierced the bucket burr 51. That is, after piercing the bottom burr 51, the first spike burr piercing cone 4411 and the second spike burr piercing cone 4421 of the first spike burr 441 and the second spike burr piercing cone 4421 of the second spike burr 442 respectively enter and pass through the first through hole 321 and the second through hole 322 of the spike head located on the right scalpel 32. Since the left and right knife-driving cylinders 41 and 31 have not yet entered the working state, the right knife-driving cylinder 31 works while the stacking barrel 5 is held. The right knife-driving cylinder column 311 extends to the left, i.e., out of the cylinder body. The right knife-driving cylinder column 311 moves the right knife 32 to the left, i.e., towards the barrel bottom edge 51, under the guidance of a pair of right knife-driving guide rods 33 (also known as "guide sliding down"). Since the bottom surface of the right knife 32 corresponds to the base of the barrel bottom edge 51, the right knife 32 separates the bottom of the barrel bottom edge 51 in the length direction from the part where it meets the bottom of the stacking barrel 5 (i.e., the barrel bottom connection part), that is, it separates the barrel bottom edge 51 from the barrel bottom. Then the right knife-driving cylinder 31 works in the opposite direction, and the right knife-driving cylinder column 311 and the right knife 32 return to the initial state to the right. In this recovery state, the first and second spikes, previously located in the first and second through holes 321 and 322 at the spike head, pierce the cones 4411 and 4421 and exit the first and second through holes 321 and 322 at the spike head. Then, the robot arm clamps the stacking bucket 5, which has been separated from the bottom spike 51, and under the reverse operation of the aforementioned backing plate opening and closing drive mechanism, the left backing plate 1 and the right backing plate 2 are displaced in a mutually repelling direction so that the robot arm can remove the stacking bucket 5 and release it onto the conveyor belt of the output device or a similar device for output. Simultaneously, the left-hand cutter drive cylinder 41 operates, extending the cylinder column 411 to the right, i.e., out of the cylinder body. The cylinder column 411 drives the left cutter 42 to move to the right under the guidance of a pair of left-hand cutter guide rods 43. This causes the left cutter 42 to expel the burrs 51 from the bottom of the buckets, which are still suspended on the first and second spikes 441 and 442, and automatically drop them onto the ground or into a burr container placed on the ground. Immediately afterwards, the left-hand cutter drive cylinder 41 reverses its operation and resets, entering a waiting state for the next operation. This process is repeated overall, thus removing the burrs 51 from the bottom of the stacked buckets 5 as needed.

[0032] In summary, the technical solution provided by this utility model makes up for the shortcomings of the prior art, successfully completes the invention task, and faithfully realizes the technical effects described by the applicant in the above technical effect column.
