Description

Technical Field

[0001] The utility model belongs to the technical field of double-turntable vacuum all-in-one machines, in particular to a double-turntable vacuum all-in-one machine. Background Art

[0002] The dual-turntable vacuum all-in-one machine is a machine developed by the food industry to address the shortage of human capital and improve the automation technology, mechanical automation, and intelligent level of production and processing enterprises. This equipment consists of an automatic rotary system for bag filling and an automatic rotary system for vacuum sealing. Its key working links are all performed by mechanical equipment, significantly reducing the need for manual operation. The dual-turntable vacuum all-in-one machine is made of food-grade 304 stainless steel, which is corrosion-resistant and rust-resistant, ensuring the service life of the machine. Its transmission device, system control and monitoring system electrical components are all imported equipment, which are characterized by high stability.

[0003] The existing double-turntable vacuum integrated machine has the following shortcomings: In the packaging bag transmission process of the existing device, the turntable clamp is used to clamp the packaging bag to ensure the stability and safety of the packaging bag during transmission. However, when the weight of the goods in the packaging bag is heavy, the problem will become prominent. Since the contact area between the clamp and the packaging bag is small, the friction generated is limited, and it is difficult to counteract the gravity of the goods, so it is very easy to slip. This slip phenomenon will seriously undermine the stability of the packaging bag transmission, causing it to shake, deviate, or even fall from the clamp during transmission. Once the fall occurs, the goods may be damaged, which will undoubtedly have an adverse effect on product quality and reduce production efficiency. In addition, although the existing flexible mechanical claws have certain advantages in some aspects, they are expensive and the operation process is very cumbersome, which is not conducive to improving the overall production efficiency and effectively controlling costs. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a double-turntable vacuum integrated machine, comprising a base and a rotating structure assembled on the top of the base, and a clamping claw structure located above the rotating structure;

[0005] The clamping structure includes a fixed box distributed in a circular array and a cylinder assembled inside the fixed box, and two symmetrically distributed fixed plates located below the cylinder. The output end of the cylinder is fixedly connected to a push block, and two guide rods are installed on the top of the fixed box to provide guidance for the push block. Two A-links are rotatably connected to the outer wall of the push block, and the end of the A-link away from the push block is rotatably connected to a clamping sleeve, and the inner wall of the clamping sleeve is rotatably connected to a B-link, and the other end of the B-link is rotatably connected to the middle of the two fixed plates.

[0006] Preferably, four fixing columns distributed in a rectangular array are installed at the bottom of the fixing box, and the four fixing columns are divided into two groups and the other ends are fixedly connected to the top surfaces of the two fixing plates respectively.

[0007] Preferably, a clamping block is fixedly mounted on the middle portion of the two clamping sleeves by means of bolts, and saw teeth are provided on the outer walls of the two clamping blocks in a linear distribution for increasing friction.

[0008] Preferably, the rotating structure includes a servo motor and a rotating rod rotatably connected to the axis of the base, and a top plate fixedly connected to the top of the rotating rod. The output end of the servo motor is fixedly connected to a driving gear.

[0009] Preferably, the outer wall of the driving gear is meshedly connected with a driven gear, and the driven gear is installed on the outside of the rotating rod.

[0010] Preferably, the fixing boxes are fixedly installed on the bottom of the top plate. When the cylinder is started, it can push the pushing block to slide on the outer wall of the guide rod and drive the A connecting rod, the clamping sleeve and the clamping block to move toward the middle under the guidance of the B connecting rod to clamp and fix the packaging bag.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model greatly improves the adaptability and clamping stability to different types of packaging bags through the design of the rotating structure and the clamping structure. When faced with a variety of different types of packaging bags, it is only necessary to start the cylinder, and the thrust generated at its output end pushes the pushing block to slide smoothly along the outer wall of the guide rod. During this process, the pushing block is tightly connected to one end of the A-link. As the pushing block moves, the B-link drives the A-link to rotate with the rotating connection between the B-link and the fixed plate as the axis, and the other end of the B-link is fixedly connected to the clamping sleeve. A clamping block is installed inside the clamping sleeve. Therefore, as the B-link rotates, the clamping sleeve and the clamping block as a whole gradually move toward the bottom, and during the movement, due to the rotation of the B-link, the two clamping blocks will gradually move closer to the middle. The serrated structure on the outer wall of the clamping block can significantly increase the friction between the clamping block and the packaging bag. When the packaging bag contains heavy items, even if the gravity of the items will produce a large downward pull or offset force on the clamping action, the strong friction between the serrated clamping block and the packaging bag can still ensure that the packaging bag is stably and reliably clamped, effectively preventing the packaging bag from slipping or displacing due to gravity or external force interference during transportation, handling or other operations, thereby ensuring the safety and efficiency of the entire packaging operation.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 5 As shown, the utility model provides a double-turntable vacuum integrated machine, comprising a base 1, a rotating structure 2 assembled on the top of the base 1, and a clamping claw structure 3 located above the rotating structure 2;

[0021] The clamping structure 3 includes a fixed box 31 distributed in a circular array and a cylinder 32 assembled inside the fixed box 31, as well as two symmetrically distributed fixed plates 33 located below the cylinder 32. The output end of the cylinder 32 is fixedly connected to a push block 34. Two guide rods 35 are installed on the top of the fixed box 31 to provide guidance for the push block 34. Two A-links 36 are rotatably connected to the outer wall of the push block 34. The end of the A-link 36 away from the push block 34 is rotatably connected to a clamping sleeve 37. The inner wall of the clamping sleeve 37 is rotatably connected to a B-link 38. The other end of the B-link 38 is rotatably connected to the middle of the two fixed plates 33.

[0022] The above solution is adopted: through the design of the rotating structure 2 and the clamping structure, the adaptability and clamping stability of different types of packaging bags are greatly improved. When faced with a variety of different types of packaging bags, it is only necessary to start the cylinder 32, and the thrust generated by its output end pushes the push block 34 to slide smoothly along the outer wall of the guide rod. In this process, the push block 34 is tightly connected to one end of the A connecting rod 36. As the push block 34 moves, the B connecting rod 38 drives the A connecting rod 36 to rotate around the rotating connection between the B connecting rod 38 and the fixed plate 33, and the other end of the B connecting rod 38 is fixedly connected to the clamping sleeve 37. A clamping block 371 is installed inside the clamping sleeve 37. As the B connecting rod 38 rotates, the clamping sleeve 37 and the clamping block 371 gradually move toward the bottom as a whole, and during the movement, due to the rotation of the B connecting rod 38, the two clamping blocks 371 will gradually Moving closer to the middle, the serrated structure of the outer wall of the clamping block 371 can significantly increase the friction between the clamping block 371 and the packaging bag. When the packaging bag contains heavier items, even if the gravity of the items will produce a large downward pull or offset force on the clamping action, the strong friction between the serrated clamping block 371 and the packaging bag can still ensure that the packaging bag is clamped stably and reliably, effectively preventing the packaging bag from slipping or displacing due to gravity or external force during transportation, handling or other operations, thereby ensuring the safety and efficiency of the entire packaging operation.

[0023] like Figures 1 to 5 As shown, four fixing columns 311 distributed in a rectangular array are installed at the bottom of the fixing box 31. The four fixing columns 311 are divided into two groups and the other ends are fixedly connected to the top surfaces of the two fixing plates 33 respectively. The middle parts of the two clamping sleeves 37 are fixed with clamping blocks 371 by bolts. The outer walls of the two clamping blocks 371 are provided with linearly distributed serrations for increasing friction.

[0024] The above scheme is adopted: the four fixing columns 311 are evenly divided into two groups, and the two fixing columns 311 in each group are firmly fixed to the top surface of the corresponding fixing plate 33. In this way, when the device faces various external forces during operation, such as the reaction force generated when clamping the packaging bag, the vibration during the operation of the equipment, etc., the supporting structure formed by the fixing columns 311 and the fixing plate 33 can effectively disperse and withstand these forces, and the middle part of the two clamping sleeves 37 is fixed with a clamping block 371 by bolts. This connection method is not only convenient for installation and disassembly, but also convenient for quick operation when the clamping block 371 is worn or needs to be replaced. At the same time, it also ensures the position stability of the clamping block 371 during operation. The serrations arranged on the outer walls of the two clamping blocks 371 can be deeply embedded in the surface of the packaging bag when the packaging bag is clamped. Without damaging the packaging bag, the contact friction between the clamping block 371 and the packaging bag is greatly increased.

[0025] like Figures 1 to 5 As shown, the rotating structure 2 includes a servo motor 21 and a rotating rod 23 rotatably connected to the axis of the base 1, and a top plate 24 fixedly connected to the top of the rotating rod 23. The output end of the servo motor 21 is fixedly connected to a driving gear 25, and the outer wall of the driving gear 25 is meshed with a driven gear 26, which is installed on the outside of the rotating rod 23.

[0026] With the above solution, the rotating structure 2 and the clamping claw structure 3 constitute the key packaging bag transmission structure in the double-turntable vacuum integrated machine, and efficiently transfer packaging bags between different stations of the double-turntable vacuum integrated machine.

[0027] like Figures 1 to 5 As shown, the fixing boxes 31 are fixedly installed at the bottom of the top plate 24. When the cylinder 32 is started, it can push the pushing block 34 to slide on the outer wall of the guide rod 35 and drive the A connecting rod 36, the clamping sleeve 37 and the clamping block 371 to move toward the middle under the guidance of the B connecting rod 38 to clamp and fix the packaging bag.

[0028] The above solution is adopted: the cylinder 32 is fixed in the fixed box 31. When the output end of the cylinder 32 pushes the pushing block 34 to move, two circular holes are opened on the inner wall of the pushing block 34 that are slidably connected to the guide rod 35. At this time, the pushing block 34 slides stably on the outer wall of the guide rod 35 through the circular holes.

[0029] The working principle of this utility model:

[0030] First, the servo motor 21 is started, and its output end drives the driving gear 25 to rotate. The driving gear 25 engages the driven gear 26, causing the rotating rod 23 to rotate, thereby driving the top plate 24 to rotate, so that the clamping claw structure 3 moves to the upper position of the packaging bag to be grasped. Then, the cylinder 32 is started, and its output end pushes the pushing block 34 to slide along the outer wall of the guide rod 35. The pushing block 34 drives the A connecting rod 36 to move. Under the action of the B connecting rod 38, the A connecting rod 36 rotates around the rotating connection between the B connecting rod 38 and the fixed plate 33, so that the clamping sleeve 37 and the clamping block 371 move to the bottom and gradually move toward the middle. The serrations on the outer wall of the clamping block 371 increase the friction force to stably grasp the packaging bag. Then, the rotating structure 2 is started again, and the clamping claw structure 3 holding the packaging bag is transferred to the designated workstation of the double-turntable vacuum integrated machine to complete the transmission of the packaging bag. Finally, the cylinder 32 operates in the reverse direction, releases the clamping block 371, puts down the packaging bag, and prepares for the next grasping and transmission cycle.
