[0002] During the pickling process of pickled vegetables such as pickled mustard tuber, pickled vegetables, and salted vegetables, after pickling is completed inside the pickling jar, it is necessary to take them out from the inside of the pickling jar for subsequent sub-packaging and sales. Initially, it was usually done manually to take out the pickled vegetables from the pickling jar, which took a lot of time and was also difficult to clean thoroughly, resulting in low efficiency.

[0003] In the prior art, the Chinese utility model patent document with the authorization announcement number of CN220412788U discloses a ceramic jar positioning and turning unloading mechanism, which drives a clamping arm to clamp the pickling jar through an electric telescopic rod. When clamping, it is difficult to control the clamping force, and situations of too large or too small clamping force are likely to occur. Too large clamping force is likely to damage the pickling jar, and too small clamping force is likely to cause the pickling jar to slip during turning.

[0004] Therefore, it is necessary to design an anti-clamping and crushing pickling jar turning and clamping device that can control the clamping force and ensure that the clamping force is appropriate to solve the current technical problems. Content of the Utility Model

[0023] Such as Figure 1 and 2As shown, the anti-crushing vegetable jar flipping and clamping device includes a frame 1. Clamping arms 2 are provided at both ends of the frame 1. A clamping drive mechanism 7 for driving the clamping arms 2 to approach or separate is provided on the frame 1. A clamping jaw assembly 3 is rotatably provided at the end of the clamping arm 2. A flipping drive mechanism for driving the clamping jaw assembly 3 to flip outward or reset is provided on the clamping arm 2. The clamping drive mechanism 7 has a clamping drive component 71 corresponding to the clamping arm 2. One end of the clamping drive component 71 is connected to the end of the clamping arm 2, and the other end of the clamping drive component 71 is fixedly provided with a force sensor 72. The force sensor 72 is fixedly provided on the frame 1. In this embodiment, the clamping drive mechanism 7 drives the two clamping arms 2 to approach or separate, and the clamping arms 2 drive the clamping jaw assemblies 3 at their ends to approach or separate to clamp or release the vegetable jar. During the clamping process, the force sensor 72 provided between the clamping drive component 71 and the frame 1 can detect the clamping force. When the clamping force reaches the set value, the clamping drive component 71 stops and remains in this clamping force state, enabling the clamping force to be controlled to ensure that the clamping force is appropriate.

[0024] In some embodiments, two guide rods 73 parallel to the clamping drive component 71 are provided at one end of the clamping arm 2 close to the clamping drive component 71. A guide tube 74 corresponding to the guide rod 73 is fixedly provided on the frame 1. The guide rod 73 is slidably provided inside the corresponding guide tube 74. The guide tube 74 is fixedly welded to the frame 1. The cooperation and sliding between the guide rod 73 and the corresponding guide tube 74 realize the sliding connection between the clamping arm 2 and the frame 1, improving the stability of the movement of the clamping arm 2.

[0025] In some embodiments, the clamping arm 2 has a clamping arm main body 21 and a clamping arm connecting plate 22. The clamping arm connecting plate 22 is vertically and fixedly provided at one end of the clamping arm main body 21. The end of the clamping arm drive component 71 facing away from the force sensor 72 is connected to the clamping arm connecting plate 22. The end of the guide rod 73 is fixedly connected to the corresponding clamping arm connecting plate 22. The clamping jaw assembly 3 is rotatably provided at one end of the clamping arm main body 21 facing away from the clamping arm connecting plate 22.

[0026] In some embodiments, two mounting plates 11 are symmetrically provided on one side of the frame 1 facing away from the clamping jaw assembly 3. The mounting plates 11 are welded and fixed to the frame 1. During use, the frame 1 can be assembled and fixed to the lifting frame of the forklift through the mounting plates 11 by means of a bolt and nut mechanism. When clamping the vegetable jar, lifting the lifting frame can lift the vegetable jar and move it to the position for scooping out the vegetables. Then, the flipping drive mechanism drives the clamping jaw assembly 3 to flip the vegetable jar and pour out the pickled vegetables inside the vegetable jar.

[0027] In some embodiments, the flipping drive mechanism has a flipping drive component 6 disposed above the clamping arm 2. One end of the flipping drive component 6 is hinged to the clamping arm 2, and a transmission plate 4 is hinged to the other end of the flipping drive component 6. The middle of the transmission plate 4 is hinged to the clamping arm 2. One end of the transmission plate 4 away from the flipping drive component 6 is connected to the outer side of the jaw assembly 3 through a connecting rod 5. One end of the connecting rod 5 is rotatably connected to the jaw assembly 3, and the other end of the connecting rod 5 is rotatably connected to the transmission plate 4. When the flipping drive component 6 extends, it pushes the transmission plate 4 to rotate, and the transmission plate 4 drives the jaw assembly 3 to flip outwards through the connecting rod 5. When the flipping drive component 6 retracts, it pulls the transmission plate 4 to reset, and the transmission plate 4 drives the jaw assembly 3 to flip inwards and reset through the connecting rod 5.

[0028] In some embodiments, the flipping drive component 6 and the clamping drive component 71 are any one of a hydraulic cylinder, a pneumatic cylinder, and an electric cylinder.

[0029] In some embodiments, as Figure 2 , 3 and shown in FIG. 4, the jaw assembly 3 has a jaw body 33 rotatably connected to the clamping arm 2. Two upper clamping blocks 31 are symmetrically arranged on the upper side of the upper end of the jaw body 33 away from the clamping arm 2, and two lower clamping blocks 32 are symmetrically arranged on the lower side of the upper end of the jaw body 33 away from the clamping arm 2. The upper clamping blocks 31 and the lower clamping blocks 32 are both hinged to the jaw body 33. During the process of the jaw body 33 approaching the pickling jar, the upper clamping blocks 31 and the lower clamping blocks 32 come into contact with the outer side of the pickling jar, and the upper clamping blocks 31 and the lower clamping blocks 32 can swing relative to the jaw body 33 to freely adjust the angle, so that the upper clamping blocks 31 and the lower clamping blocks 32 are stably attached to each other to adapt to pickling jars of different diameters.

[0030] In some embodiments, as Figure 3 shown, the lower clamping block 32 has a lower cushion block 321. A lower support plate 322 is arranged on one side of the lower cushion block 321. A lower connecting seat 323 is fixedly arranged on the side of the lower support plate 322 away from the lower cushion block 321. The lower connecting seat 323 is hinged to the jaw body 33. A first hole 324 is opened in the lower connecting seat 323, and a second hole 325 corresponding to the first hole 324 is opened in the jaw body 33. A tension spring (the tension spring is not shown in the figure) is arranged between the first hole 324 and the second hole 325. The two ends of the tension spring are respectively hung in the first hole 324 and the second hole 325. As Figure 3As shown, the upper clamping block 31 has an upper cushion block 311. On one side of the upper cushion block 311, there is an upper support plate 312. On the side of the upper support plate 312 away from the upper cushion block 311, there is a fixed upper connecting seat 313. The upper connecting seat 313 is hinged to the jaw body 33. A third hole 314 is formed in the upper connecting seat 313, and a fourth hole 315 corresponding to the third hole 314 is formed in the jaw body 33. A tension spring is arranged between the third hole 314 and the fourth hole 315; the upper clamping block 31 and the lower clamping block 32 are in contact with the outer side of the pickle jar. The upper clamping block 31 and the lower clamping block 32 can swing relative to the jaw body 33 to freely adjust the angle, so that the upper clamping block 31 and the lower clamping block 32 are stably attached to each other to adapt to pickle jars of different diameters. The tension spring can automatically reset after the upper clamping block 31 and the lower clamping block 32 are separated from the pickle jar.

[0031] In some embodiments, the upper cushion block 311 is a V-shaped structure that matches the upper annular groove of the pickle jar, which can increase the contact area with the upper annular groove of the pickle jar.
