[0003] In the prior art, the edge sanding machine includes a frame, an edge sanding unit, a conveying device, and a positioning device. During use, the cookware is fixed on the conveying device through the positioning device, and the conveying device drives the cookware to pass through the edge sanding unit to process the edges of the cookware. After processing, the conveying device takes the cookware out of the working area, that is, the processing of the edges of the cookware is completed.

[0004] Although the existing edge sanding machines have the advantages of high processing efficiency and simple and convenient operation, their positioning devices cannot adjust the angle, resulting in the edge sanding unit not being able to fit well with the edges of the cookware for grinding, seriously affecting the qualification rate of the finished cookware. Summary of the Invention

As shown in Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown in the figure, the horizontally placed rotating assembly 221 includes at least one set of horizontally placed positioning seats 2211, a rotating shaft 2212 connected to the horizontally placed positioning seats 2211, and a direction-changing manual adjustment block 2213 connected to one end of the rotating shaft 2212. One set of horizontally placed positioning seats 2211 includes two positioning seats 22111. The two positioning seats 22111 are distributed horizontally and are respectively fixed on the sliding base 21.

[0052] Continue to refer to Figure 5 , and refer to Figure 7 ,Figure 8 and Figure 9 , Figure 7 Figure 5 is a perspective view of a mold connection block in a sanding edge machine that is convenient for adjusting the angle according to the present application. Figure 8 Figure 6 is a perspective view of another angle of the mold connection block in a sanding edge machine that is convenient for adjusting the angle according to the present application. Figure 9 Figure 7 is a cross-sectional structure diagram of another angle of the mold connection block in a sanding edge machine that is convenient for adjusting the angle according to the present application. As shown in FIGS. Figure 5 、 Figure 7 、 Figure 8 and Figure 9 shown, the mold connection block 2223 includes a connection chassis 22231, a connection sleeve 22232 connected to the connection chassis 22231, and a connection head 22233 elastically connected to the connection sleeve 22232.

The support plate 222331 is placed outside the connection sleeve 22232, so as to form an elastic limit connection between the connection sleeve 22232 and the connection head 22233, and prevent the support plate 222331 from detaching from the connection sleeve 22232.

[0053] Refer to Figure 10 、 Figure 11 、 Figure 12 and Figure 13 , Figure 10 Figure 8 is a perspective view of a mold in a sanding edge machine that is convenient for adjusting the angle according to the present application. Figure 11 Figure 9 is a schematic diagram of the first installation state of the mold and the mold connection block in a sanding edge machine that is convenient for adjusting the angle according to the present application. Figure 12 Figure 10 is a schematic diagram of the second installation state of the mold and the mold connection block in a sanding edge machine that is convenient for adjusting the angle according to the present application. Figure 13 is Figure 12 The enlarged view of the circled area A in. As shown in FIGS. Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown in the figure, the mold 223 includes a mold plate 2231 and at least one set of movable locking brackets 2232 connected to the bottom of the mold plate 2231. One set of movable locking brackets 2232 includes three movable locking brackets 2232. The movable locking brackets 2232 are respectively matched with the limit holes 22233A, the arc-shaped grooves 22232A and the limit grooves 22231A. Specifically, the movable locking bracket 2232 includes a short locking rod 22321, a medium locking rod 22322 and a long locking rod 22323. The short locking rod 22321, the medium locking rod 22322 and the long locking rod 22323 are hinged to each other. When the mold 223 is connected to the mold connection block 2223, the mold plate 2231 is placed on the support plate 222331. The movable locking bracket 2232 passes through the connection head 22233 through the limit hole 22233A on the connection head 22233, and is matched with the arc-shaped groove 22232A on the connection sleeve 22232, and abuts against the limit groove 22231A. Specifically, when the mold 223 is connected to the mold connection block 2223, the short locking rod 22321, the medium locking rod 22322 and the long locking rod 22323 all pass through the connection head 22233 through the limit hole 22233A. Among them, the free end of the long locking rod 22323 extends into the limit groove 22231A, and the side wall of the long locking rod 22323 fits with the arc-shaped groove 22232A. At the same time, the hinge joint of the short locking rod 22321 and the medium locking rod 22322 just abuts against the bottom of the support plate 222331. At this time, under the action of the limit hole 22233A on the connection head 22233, the short locking rod 22321 remains vertical, and under the action of the limit groove 22231A on the connection chassis 22231, the long locking rod 22323 remains vertical, while the medium locking rod 22322 remains inclined. Due to the inclined angle of the medium locking rod 22322, the position of the mold plate 2231 is limited at the connection between the medium locking rod 22322 and the short locking rod 22321 or the inclined position below the connection on the medium locking rod 22322, so as to realize the limitation of the mold 223 by the mold connection block 2223 and realize the stable and rapid installation of the mold 223.

[0054] Here, through the movable locking frame 2232 provided at the bottom of the mold plate 2231, through the mutual cooperation between the short locking rod 22321, the middle locking rod 22322, and the long locking rod 22323 in the movable locking frame 2232 and the limit hole 22233A, the arc-shaped groove 22232A, and the limit groove 22231A respectively. Specifically, the short locking rod 22321, the middle locking rod 22322, and the long locking rod 22323 are hinged to each other. The short locking rod 22321 cooperates with the limit hole 22233A, the middle locking rod 22322 fits with the arc-shaped groove 22232A, and the long locking rod 22323 cooperates with the limit groove 22231A. And an elastic component 222334 is sleeved on the connecting rod 222332 in the connecting head 22233. Thus, the elastic component 222334 is located between the retaining ring 222321 and the limit plate 222333. The support plate 222331 is placed outside the connecting sleeve 22232, realizing that the connection position between the middle locking rod 22322 and the short locking rod 22321 or the inclined position below the connection position on the middle locking rod 22322 abuts against the bottom of the support plate 222331, thereby forming the limitation of the position of the mold plate 2231 and completing the installation of the mold plate 2231. When it is necessary to remove the mold plate 2231, manually lift the support plate 222331 to increase the distance between the support plate 222331 and the connection chassis 22231. At the same time, hold the long locking rod 22323 tightly to keep the long locking rod 22323 always vertical. Thus, while lifting the support plate 222331, the long locking rod 22323, the middle locking rod 22322, and the short locking rod 22321 move upward simultaneously, so that the long locking rod 22323 disengages from the limit groove 22231A, the middle locking rod 22322 disengages from the arc-shaped groove 22232A, and the movable locking frame 2232 returns to the unlocked state. The middle locking rod 22322 and the long locking rod 22323 droop naturally. At this time, the mold plate 2231 can be manually lifted, so that the short locking rod 22321, the middle locking rod 22322, and the long locking rod 22323 disengage from the limit hole 22233A in sequence, that is, the mold 223 is removed. Further optimized, in the daily use process of the existing sander, for the installation of molds 223 of different specifications, it is necessary to fix them with multiple bolts to complete the installation, which is very inconvenient to operate, time-consuming and laborious. It effectively improves the convenience of operation, reduces the operation difficulty, and at the same time, improves the work efficiency.

The sanding edge unit 31 in the sanding edge device 30 is connected to a lifting adjustment mechanism 32 and a horizontal adjustment mechanism 33. Both the lifting adjustment mechanism 32 and the horizontal adjustment mechanism 33 are controlled by an external handwheel 22132. During the process of processing the edge of the cookware, the angle of the positioning device of the sanding edge machine can be adjusted, effectively improving the qualified rate of the finished cookware products.

[0059] For ease of understanding, the working principle of the present application is further described as follows: For the sanding edge machine with adjustable angle, first, the direction-changing rotating block 22131 is controlled by the handwheel 22132, and the direction-changing rotating block 22131 drives the rotating shaft 2212 to rotate. Refer to Figure 14 , Figure 14 is a structural diagram of another perspective of the rotary positioning device in a sanding edge machine with adjustable angle according to the present application. According to the needs of the on-site environment and the position of the sanding edge device 30, the angle of the mold connection block 2223 in the preset direction is adjusted, thereby adjusting the angle of the mold 223 to ensure that the sanding edge unit 31 can fit well with the edge of the product for grinding, improving the qualified rate of the product;

[0060] During the installation of the mold 223, first, the long locking rod 22323, the middle locking rod 22322, and the short locking rod 22321 in the movable locking frame 2232 of the mold 223 are successively passed through the limiting holes 22233A on the support plate 222331. Then, by manually lifting the support plate 222331, the position between the support plate 222331 and the connection plate is finely adjusted, and the mold plate 2231 is driven to move upward, so that the long locking rod 22323 is inserted into the limiting groove 22231A and closely adheres to the arc-shaped groove 22232A. At this time, the short locking rod 22321 and the long locking rod 22323 are both in a vertical state, and the middle locking rod 22322 is in an inclined state. The connection point between the middle locking rod 22322 and the short locking rod 22321 or the inclined position below the connection point on the middle locking rod 22322 abuts against the bottom of the support plate 222331. Thus, the bottom of the support plate 222331 limits the middle locking rod 22322 on the movable locking frame 2232 to realize the limitation of the mold 223. At this time, without manually lifting the support plate 222331, the hinge point or other inclined points of the middle locking rod 22322 always abut against the bottom of the support plate 222331, so that the mold 223 does not separate from the mold connection block 2223, thus completing the installation of the mold 223;

[0061] When disassembling the mold 223, hold the long locking rod 22323 gently with one hand and lift the support plate 222331 upward with the other hand to increase the distance between the support plate 222331 and the connection chassis 22231. After the long locking rod 22323 disengages from the limiting groove 22231A, release the long locking rod 22323 at this time. After the middle locking rod 22322 and the long locking rod 22323 in the movable locking frame 2232 are in a natural state, release the lifted support plate 222331, and the support plate 222331 returns to its initial position under elastic limitation. Finally, hold the mold plate 2231 with your hand and lift the whole mold 223 upward until the short locking rod 22321, the middle locking rod 22322, and the long locking rod 22323 completely disengage from the limiting holes 22233A, that is, complete the disassembly of the mold 223 from the mold connection block 2223, effectively improving the convenience of operation, reducing the operation difficulty, and at the same time, improving the work efficiency and avoiding the use of cumbersome bolt fixing methods. Here, the middle locking rod 22322 and the long locking rod 22323 being in a natural state means that the long locking rod 22323 naturally adheres to the outer wall of the connection plate. At the same time, under the action of the long locking rod 22323, the middle locking rod 22322 is in a naturally extended state. Continue to refer to Figure 9 and Figure 12 , in addition, when lifting the support plate 222331 upward, the movable distance L1 of the support plate 222331 is greater than the length L2 of the long locking rod 22323 extending into the limiting groove 22231A, that is, L1 > L2.
