One end of the connecting sleeve 22232 is provided with a retaining ring 222321. The connecting head 22233 is provided with a limiting hole 22233A. The connecting head 22233 includes a support plate 222331, a connecting rod 222332 connected to the support plate 222331, and a limiting hole 22233A connected to the connecting rod 222332. Specifically, the support plate 222331 has a limiting hole 22233A; the connecting rod 222332 passes through the connecting sleeve 22232 through the retaining ring 222321; the limiting plate 222333 is placed inside the connecting sleeve 22232; an elastic component 222334 is provided between the limiting plate 222333 and the retaining ring 222321; the elastic component 222334 is sleeved on the connecting rod 222332; and the support plate 222331 is placed outside the connecting sleeve 22232, thereby forming an elastic limiting connection between the connecting sleeve 22232 and the connector 22233, preventing the support plate 222331 from detaching from the connecting sleeve 22232.

[0053] refer to Figure 10 , Figure 11 , Figure 12 and Figure 13 , Figure 10 This is a perspective view of a mold in a sanding machine that is easy to adjust the angle, as described in this application. Figure 11 This is a schematic diagram showing the installation state of the mold and mold connecting block in a sanding machine that facilitates angle adjustment, according to this application. Figure 12 This is a schematic diagram showing the installation state of the mold and mold connecting block in a sanding machine that is easy to adjust the angle, according to the present application. Figure 13 yes Figure 12 A magnified view of circle A. (See image below.) Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, mold 223 includes mold plate 2231 and at least one set of movable locking brackets 2232 connected to the bottom of mold plate 2231. Each set of movable locking brackets 2232 includes three movable locking brackets 2232, which respectively cooperate with limiting holes 22233A, arc-shaped grooves 22232A, and limiting slots 22231A. Specifically, each movable locking bracket 2232 includes a short locking rod 22321, a middle locking rod 22322, and a long locking rod 22323. The short locking rod 22321 and the middle locking rod 22322... The long locking rods 22323 are hinged together. When the mold 223 is connected to the mold connecting block 2223, the mold plate 2231 is placed on the support plate 222331. The movable locking frame 2232 passes through the limiting hole 22233A on the connector 22233 and cooperates with the arc-shaped groove 22232A on the connecting sleeve 22232, and abuts against the limiting groove 22231A. Specifically, when the mold 223 is connected to the mold connecting block 2223, the short locking rod 22321 and the middle locking rod... Both 22322 and the long locking rod 22323 pass through the limiting hole 22233A into the connector 22233. The free end of the long locking rod 22323 extends into the limiting groove 22231A, and its sidewall fits against the arc-shaped groove 22232A. Simultaneously, the hinge joint between the short locking rod 22321 and the middle locking rod 22322 abuts against the bottom of the support plate 222331. At this point, the short locking rod 22321, under the action of the limiting hole 22233A on the connector 22233,... The long locking rod 22323 remains vertical under the action of the limiting groove 22231A on the connecting base 22231, while the middle locking rod 22322 remains inclined. Since the middle locking rod 22322 has an inclined angle, the inclined position below the connection point of the middle locking rod 22322 and the short locking rod 22321 or the connection point on the middle locking rod 22322 limits the position of the mold plate 2231, so as to realize the limitation of the mold 223 by the mold connecting block 2223, and realize the stable and quick installation of the mold 223.

[0054] Here, through the movable locking frame 2232 set at the bottom of the mold plate 2231, the short locking rod 22321, the middle locking rod 22322, and the long locking rod 22323 in the movable locking frame 2232 respectively cooperate with the limiting hole 22233A, the arc-shaped groove 22232A, and the limiting slot 22231A. Specifically, the short locking rod 22321, the middle locking rod 22322, and the long locking rod 22323 are hinged together. The short locking rod 22321 cooperates with the limiting hole 22233A, the middle locking rod 22322 fits against the arc-shaped groove 22232A, and the long locking rod 22323... 323 cooperates with the limiting groove 22231A, and an elastic component 222334 is sleeved on the connecting rod 222332 in the connector 22233. Thus, the elastic component 222334 is located between the retaining ring 222321 and the limiting plate 222333. The support plate 222331 is placed outside the connecting sleeve 22232. This allows the inclined position below the connection point of the middle locking rod 22322 and the short locking rod 22321 or the connection point on the middle locking rod 22322 to abut against the bottom of the support plate 222331, thereby defining the position of the mold plate 2231 and completing the mold plate 223. For installation 1, if 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 connecting base plate 22231. At the same time, firmly grasp the long locking rod 22323 to keep it vertical. This will lift the support plate 222331 and simultaneously move the long locking rod 22323, the middle locking rod 22322, and the short locking rod 22321 upwards. This will cause the long locking rod 22323 to disengage from the limiting groove 22231A, the middle locking rod 22322 to disengage from the arc-shaped groove 22232A, and the movable locking bracket 2232 to return to its original position. When the machine is in the unlocked state, the middle locking rod 22322 and the long locking rod 22323 hang down 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 limiting hole 22233A in sequence, thus removing the mold 223. This further optimizes the existing sanding machine, which requires multiple bolts to fix the mold 223 of different specifications during daily use. This is very inconvenient, time-consuming, and labor-intensive. It effectively improves the convenience of operation, reduces the difficulty of operation, and improves work efficiency.

A lifting rod 3212 is connected to a locking assembly 3211 to lock the lifting rod 3212, restricting its rotation and thus locking the manual adjustment unit 321. A support plate 3213 is connected to the lifting rod 3212, and lifting rods 3214 are respectively provided at the four corners of the support plate 3213 to improve the stability of the support plate 3213 during the lifting process. Specifically, the lifting rod 3212 is raised and lowered by controlling the handwheel 22132 and under the action of the reversing block 22131. At the same time, the lifting rods 3214 are also raised and lowered. After the support plate 3213 reaches the desired position, it is locked by the locking assembly 3211 to lock the position of the support plate 3213. It should be noted that the lifting rod 3212 can be lifted by a cylinder or by an electric motor.

[0056] The locking assembly 3211 includes an open locking seat 32111, a locking rod 32112 connected to the open locking seat 32111, and a rotating head 32113 connected to the locking rod 32112. A slotted hole is provided on the frame 10 at a position corresponding to the locking rod 32112 to achieve synchronous movement with the reversing rotating block 22131. The locking rod 32112 passes through the slotted hole from the inside to the outside of the frame 10 and connects to the rotating head 32113. In use, the rotating head 32113 is controlled to drive the locking rod 32112 to rotate. The locking rod 32112 and the open locking seat 32111 are threaded together. The rotation of the locking rod 32112 causes the opening of the open locking seat 32111 to retract, clamping the lifting rod 3212 to constrain it until it cannot rotate, thus controlling the lifting distance of the lifting rod 3212. The position of the pallet 3213 is controlled by the lifting and lowering mechanism. In addition, the automatic lifting adjustment unit 322 is connected to the bottom of the pallet 3213. The pallet 3213 is also provided with a clearance hole 3213A.

The lifting and lowering components 3223 and the automatic lifting components 3222 are all connected to the horizontal adjustment mechanism 33 to control the lifting and lowering of the horizontal adjustment mechanism 33, thereby controlling the lifting and lowering of the sanding edge unit 31.

[0057] The horizontal adjustment mechanism 33 is also controlled by an external handwheel 22132 to adjust the horizontal position of the sanding unit 31 according to the processing position required by the product. The horizontal adjustment mechanism 33 includes a fixed plate 331 and a horizontal adjustment unit 332 connected to the fixed plate 331. The fixed plate 331 is connected to the lifting assembly 3223 and the automatic lifting assembly 3222. The horizontal adjustment unit 332 includes a base 3321, an adjustment platform 3322 slidably connected to the base 3321, and an adjustment rod 3323 disposed between the base 3321 and the adjustment platform 3322. The lever 3323 can rotate freely inside the base 3321 and the adjusting platform 3322. Specifically, the adjusting lever 3323 is threaded, and the inner wall of the adjusting platform 3322 is also threaded corresponding to the position of the adjusting lever 3323. The thread on the adjusting lever 3323 and the thread on the adjusting platform 3322 cooperate to adjust the horizontal position of the adjusting platform, thereby driving the sanding unit 31 to adjust horizontally. In addition, a locking component 3211 is provided at one end of the base 332 to lock the adjusting lever 3323 and prevent the adjusting lever 3323 from rotating arbitrarily.

[0058] Here, the frame 10 is provided with at least one set of sliding rails 11, and the frame 10 is also fixed with a telescopic mechanism 12; the rotary positioning device 20 is slidably connected to the frame 10, and the rotary positioning mechanism 22 in the rotary positioning device 20 is fixed to the sliding base 21. The sliding base 21 is slidably connected to the sliding rails 11. The bottom of the sliding base 21 is provided with a connecting piece 211, which is connected to the telescopic mechanism 12. Through the mutual cooperation between the connecting piece 211 and the telescopic mechanism 12, the sliding base 21 is driven by the telescopic mechanism 12 to perform telescopic movement.

The adjusting block 2213, the universal joint block 2221 in the longitudinally placed rotating assembly 222 is connected to the rotating module 2222, the universal joint block 2221 is connected to the rotating shaft 2212 and rotates synchronously with the rotating shaft 2212, the rotating module 2222 extends from the bottom of the universal joint block 2221 to the top of the universal joint block 2221, and the extended end of the rotating module 2222 is connected to the mold connecting block 2223, the mold 223 is detachably connected to the mold connecting block 2223, and the rotating module 2222 extends from the bottom of the universal joint block 2221 to the top of the universal joint block 2221. The moving module 2222 extends into the lower part of the sliding base 21 through the opening 21A. The adjustable sanding device 30 is also connected to the frame 10. The sanding unit 31 in the sanding device 30 is connected to the lifting adjustment mechanism 32 and the horizontal adjustment mechanism 33. Both the lifting adjustment mechanism 32 and the horizontal adjustment mechanism 33 are controlled by the external handwheel 22132, so that the angle of the positioning device of the sanding machine can be adjusted during the process of processing the edge of the cookware, which effectively improves the qualification rate of the finished cookware.

[0059] To facilitate understanding, the working principle of this application is further described as follows: For an angle-adjustable sander, firstly, the handwheel 22132 controls the direction-changing rotating block 22131, which in turn drives the rotating shaft 2212 to rotate. (Refer to...) Figure 14 , Figure 14 This is a structural diagram of the rotary positioning device in a sanding machine that is easy to adjust the angle of the present application. The angle of the mold connecting block 2223 in the preset direction is adjusted according to the needs of the site environment and the position of the sanding device 30, so as to adjust the angle of the mold 223 so that the sanding unit 31 can fit well with the edge of the product for sanding, thereby improving the product qualification rate.

[0060] During the installation of mold 223, firstly, the long locking rod 22323, the middle locking rod 22322, and the short locking rod 22321 in the movable locking bracket 2232 of mold 223 are sequentially passed through the limiting hole 22233A on the support plate 222331. Then, the position between the support plate 222331 and the connecting plate is finely adjusted by manually lifting the support plate 222331, which in turn moves the mold plate 2231 upward, so that the long locking rod 22323 is inserted into the limiting groove 22231A and closely abuts the arc-shaped groove 22232A. At this time, both the short locking rod 22321 and the long locking rod 22323 remain vertical, and the middle locking rod 22322... In the tilted state, the connection point of the middle locking rod 22322 and the short locking rod 22321, or the tilted position below the connection point of the middle locking rod 22322, abuts against the bottom of the support plate 222331. This forms a limit on the bottom of the support plate 222331 by the middle locking rod 22322 on the movable locking frame 2232, thereby limiting the mold 223. At this time, without manually lifting the support plate 222331, the hinge point or other tilted part of the middle locking rod 22322 always abuts against the bottom of the support plate 222331, so that the mold 223 does not detach from the mold connecting block 2223, thus completing the installation of the mold 223.

[0061] When disassembling mold 223, one hand gently holds the long locking rod 22323, while the other hand lifts the support plate 222331 upwards to increase the distance between the support plate 222331 and the connecting chassis 22231. This allows the long locking rod 22323 to disengage from the limiting groove 22231A. Then, the hand releases the long locking rod 22323. After the middle locking rod 22322 and the long locking rod 22323 in the movable locking frame 2232 are in their natural state, the lifted support plate 22233 is released. 1. The support plate 222331 returns to its initial position under elastic limiting. Finally, holding the mold plate 2231, lift the mold 223 upwards as a whole until the short locking rod 22321, the middle locking rod 22322, and the long locking rod 22323 are completely disengaged from the limiting hole 22233A. This completes the disassembly of the mold 223 from the mold connecting block 2223, effectively improving the convenience of operation, reducing the difficulty of operation, and improving work efficiency, while 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 is naturally in contact with the outer wall of the connecting plate, while the middle locking rod 22322 is naturally extended under the action of the long locking rod 22323. Continue to refer to... Figure 9 and Figure 12 Furthermore, when the support plate 222331 is lifted 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.
