In addition, the three-dimensional space of length, width and depth should be included in actual fabrication.

Referring to fig. 1-13, a turnover device includes a chassis 1, where the chassis 1 includes a first surface and a second surface perpendicular to each other;

the first slide plate assembly 2, the first slide plate assembly 2 comprises a first slide plate 21, the first slide plate 21 is connected to the first surface through a first driving device, the first slide plate 21 can slide through the first driving device, the sliding direction is perpendicular to the second surface, and the first slide plate is used for bearing the lateral surface of the blank;

the second slide plate assembly 3 comprises a second slide plate, the second slide plate is connected to the second surface through a second driving device, the second slide plate can slide through the second driving device, the sliding direction is perpendicular to the first surface, and the second slide plate is used for bearing the bottom surface of the blank;

the scraper assembly 4, the scraper assembly 4 comprises a scraper 41, the movement track of the scraper 41 is positioned in a gap between the first sliding plate 21 and the second sliding plate, and the scraper 41 is parallel to the second sliding plate and is used for removing the bottom skin 51 of the bottom surface of the block. According to the application, the bottom skin 51 at the bottom end of the blank body 5 is scraped by the scraper 41, so that the bottom skin 51 is prevented from being remained, the blank body 5 is not tightly attached to the bottom plate, and the blank body 5 is cracked due to a cutting procedure after the blank body is discharged from the kettle.

Compared with the process of self-falling of the bottom leather 51 by gravity in the prior art, the bottom leather 51 can be completely removed by using the application, the phenomenon of residual bottom leather 51 is avoided, and the process problem caused by incomplete removal of the bottom leather 51 can be completely avoided.

Further, other points are the same as those of the above embodiment, except that the doctor blade 41 is connected to a third transmission mechanism, and both the doctor blade 41 and the third transmission mechanism are connected to the first slide plate 21.

Referring to fig. 13, in the use of the turning device, when the chassis 1 is parallel to the horizontal plane with the first slide plate 21, the blank 5 and the first slide plate 21 are kept relatively still all the time, and the embodiment, by mounting the doctor blade 41 on the first slide plate 21 to keep the doctor blade 41 and the first slide plate 21 relatively still, enables the doctor blade 41 and the blank 5 to be kept relatively still, so that the doctor blade 41 can accurately align with the bottom skin 51 for operation even if no directional calibration is required before operation, and the doctor blade 41 can always keep parallel to the bottom surface of the blank 5 regardless of rotation of the chassis 1, thereby fundamentally avoiding the operation error of the doctor blade 41.

In other embodiments of the application, other technical points are identical to those of the above embodiments, except that the doctor blade 41 is attached to the chassis 1.

30 it will be appreciated that in order to enable scraping of the doctor blade 41 parallel to the bottom surface of the block from the junction of the bottom skin 51 and the block, a sensor is provided between the first slide plate 21 and the doctor blade 41 to stop the movement at the moment of contact of the slide plate with the doctor blade 41, so that it is possible to ensure that the doctor blade 41 is aligned with the junction of the blank 5 and the bottom skin 51 and to avoid that the first slide plate 21 presses the doctor blade 41 so that the doctor blade 41 tilts.

The sensor may be a photoelectric sensor or a proximity switch, and when the sensor detects that the first sliding plate 21 just contacts the scraper 41 in a use process, the power of the first sliding plate 21 is interrupted, the first sliding plate 21 stops moving, so that the scraper 41 is prevented from being forced to force so as to cause the angle change of the scraper 41, and meanwhile, the scraper 41 is tightly attached to the connection part of the blank 5 and the bottom skin 51.

Further, when the doctor blade 41 is mounted on the first slide plate 21, the power of the doctor blade 41 is derived from the first power source 23 of the first slide plate 21, and in some embodiments of the application, the first power source 23 is the first cylinder 231.

The design difficulty of the turnover equipment can be simplified by using the same power source, and the turnover equipment is also convenient to directly improve on the existing design.

In other embodiments of the present application, the doctor blade 41 is driven by a second power source independent of the first power source 23, and the second power source may be a power source directly providing a linear power output by an oil cylinder, an air cylinder, a ball screw, or the like, or may be a power source providing a rotary power output by a motor, or the like. If the second power source is a power source that provides a rotational power output, a device that converts the rotational power output into a linear output needs to be added at the rear to drive the scraper 41 to perform linear reciprocating motion.

Referring to fig. 9-12, in some embodiments of the application, when the first slide 21 and the doctor blade 41 share a power source, the first driving device includes a transfer device thereon, and the third transmission mechanism is connected to the transfer device to obtain power.

The transfer device is able to direct power on the first drive to the third transmission to power the doctor blade 41.

Further, the first driving device comprises a slide plate bracket 22 and a first power source 23, the slide plate bracket 22 is connected with the chassis 1, the first power source 23 is respectively connected with the slide plate bracket 22 and the first slide plate 21, and the first power source 23 is used for driving the first slide plate 21 to generate relative motion relative to the slide plate bracket 22.

In some embodiments of the present application, the first power source 23 may be an oil cylinder, a ball screw, etc. that provides a linear power output, and in other embodiments of the present application, the first power source 23 may be a motor that provides a rotational power output, etc. A first guiding means 24 is also arranged between the slide bracket 22 and the first slide 21, which first guiding means 24 may be a linear bearing 242 and a shaft 241.

Referring to fig. 5 and 6 for example, since the first power source 23 is single or multiple, due to the long length of the first slide plate 21, synchronization of two ends of the first slide plate 21 needs to be ensured during sliding of the first slide plate 21, further, the first driving device further includes a synchronization device, the synchronization device includes a first rotation shaft 251, a synchronization gear 253, and a synchronization rack 254, the first rotation shaft 251 is connected with the first slide plate 21 through a bearing block 252, two synchronization gears 253 are connected on the first rotation shaft 251, the synchronization rack 254 is connected with the slide plate bracket 22, the synchronization gear 253 is meshed with the synchronization rack 254, and the two synchronization gears 253 are respectively located on two sides of a symmetry plane of the first slide plate 21.

In this embodiment, the moving speeds of both ends of the first slider 21 are made the same by providing the first rotating shaft 251 so as to synchronize both ends of the first slider 21.

Further, referring to fig. 9-12, the transfer device includes a second rotating shaft 423, the second rotating shaft 423 is connected to the first sliding plate 21 through a bearing block 252, the second rotating shaft 423 is connected to a side closer to the second sliding plate than the first rotating shaft 251, and the first rotating shaft 251 and the second rotating shaft 423 are driven through a chain 421 and a sprocket 422.

In order to make the structure of the driving device simpler, the distance between the shaft 241 of the first rotating shaft 251 and the second rotating shaft 423 is preferably kept unchanged, so that the existing driving structure such as a chain 421, a sprocket 422, a gear set, a belt pulley, a belt and the like can be selected for driving power, so that in the embodiment, both the first rotating shaft 251 and the second rotating shaft 423 are connected to the first sliding plate 21.

Specifically, in order to keep the rotation speeds of both ends of the second rotation shaft 423 synchronous, two sets of chains 421 and sprockets 422 are respectively disposed at both ends of the second rotation shaft 423 and the first rotation shaft 251.

Further, referring to fig. 11-12, the third transmission mechanism includes a main gear 431 and a main rack 434, the main gear 431 is sleeved on the second rotating shaft 423, the main rack 434 is connected to the scraper 41, and the main gear 431 drives the main rack 434.

Referring to fig. 12, in some embodiments of the present application, since the main gear 431 cannot directly mesh with the main rack 434 due to space arrangement, gear ratio, etc., the third transmission mechanism further includes a gear set, through which not only the main gear 431 and the main rack 434 can be connected to be meshed with each other, but also the total gear ratio of the transmission device and the third transmission mechanism can be adjusted, the gear set includes an idle gear 432 and a driven gear 433, the idle gear 432 and the driven gear 433 are meshed with each other, the idle gear 432 is meshed with the main gear 431, and the driven gear 433 is meshed with the main rack 434.

Further, the total gear ratio of the transfer device and the third transmission mechanism is less than 1, that is, the rotation speed of the second rotation shaft 423 divided by the rotation speed of the driven gear 433 is less than 1.

Since the first slide plate 21 is moved to separate the bottom skin 51 from the side plate 6 and drop, the moving distance of the first slide plate 21 does not exceed the thickness of the bottom skin 51 by a large amount, and the stroke of the doctor blade 41 is at least equal to the sum of the thickness of the bottom skin 51 and the height of the blank 5, i.e. the stroke of the doctor blade 41 is far greater than the stroke of the first slide plate 21, and the doctor blade 41 and the first slide plate 21 share the same power source, the device in the application is not provided with a clutch to respectively enable the power sources to supply power to the doctor blade 41 and the first slide plate 21, and a device capable of adjusting the transmission ratio, namely a gear box, is arranged between the doctor blade 41 and the first power source 23 to enable the strokes of the first slide plate 21 and the doctor blade 41 to be different.

And setting the total gear ratio to be less than 1 enables the doctor blade 41 to move by a larger stroke when the first slider 21 moves by a smaller stroke, specifically, the value of the total gear ratio is equal to the ratio of the stroke of the doctor blade 41 to the stroke of the first slider 21.

Referring to fig. 13, in some embodiments of the present application, when the bottom skin 51 is further contacted with the second sliding plate, the distance between the upper end surface of the scraper 41 and the bottom skin 51 is greater than 0, that is, the scraper 41 needs to move upwards for a distance after receiving the power, and then can contact with the bottom skin 51.

The reason that a distance is left between the bottom skin 51 and the initial position of the scraper 41 is to make enough space for the bottom skin 51 to fall after the bottom skin 51 leaves the second slide plate, so that the situation that the bottom skin 51 cannot fall due to insufficient space is avoided, the scraper 41 pushes the bottom skin 51 up to the blank 5, and the bottom skin 51 which is pushed up after the chassis 1 is overturned falls on the side plate 6 to cause residues of the bottom skin 51 to enter the kettle.

Referring to fig. 12, in some embodiments of the present application, the upper end of the doctor blade 41 is narrower and thicker, and the surface of the doctor blade 41 near the bottom surface of the blank 5 is always a plane.

The doctor blade 41 is also provided in a structure having a narrow upper portion and a thick lower portion in order to make a space between the doctor blade 41 and the side plate 6 for the bottom sheet 51 to smoothly fall down.

Referring to fig. 1 and 2 for example, it will be appreciated that, due to the longer length of the doctor blade 41, in order to synchronize the movement of the two ends of the doctor blade 41, a second guide means is provided between the doctor blade 41 and the first slide plate 21, said second guide means comprising a linear bearing 242 and a shaft 241.

4. the underframe 1 is turned over until the first sliding plate 21 is parallel to the horizontal plane, referring to fig. 13, the distance between the top end of the scraper 41 and the upper end surface of the blank 5 is a1, the width d of the blank, the distance between the blank and the side plate is b1, the thickness of the bottom skin is d2, at this time, a1 is greater than d, and b1=d;

5. the first power source 23 drives the first slide plate 21 to move along the blank 5 in a direction away from the second slide plate, wherein a=d, and b > d;

6. the first power source 23 drives the first slide plate 21 to drive the blank 5 to move away from the second slide plate, and meanwhile, the first power source 23 also drives the scraper 41 to move upwards to scrape the bottom surface of the blank 5 and remove the bottom skin 51, and at the moment, a is smaller than d, and b is larger than d;
