DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention is described below in conjunction with specific implementation methods and drawings.

[0025] This technical solution takes the clamping of spherical vegetables as an example. The automatic clamping tool and conveying system of this technical solution clamp the spherical vegetables when used, so that the mechanical vegetable cutter can cut the roots and seedlings of the vegetables.

[0026] Example 1

[0027] like Figure 1 , 2 , 3, 5, and 6, an automatic clamping tool based on a conveyor belt includes a bracket 10, a driving shaft 20, a driving gear 21, a first driven gear 30, a second driven gear 40, a first clamping jaw 50, a second clamping jaw 60, a first rotating shaft 31, a second rotating shaft 41, and a rotating roller 70. The bracket can be designed with a single plate or a double plate. Regardless of the single plate design or the double plate design, a driving shaft hole 22, a first shaft hole 32, and a second shaft hole 42 need to be set on the bracket. The first shaft hole and the second shaft hole are set at the same height on the upper part of the bracket. The driven shaft hole is arranged at the lower part of the bracket, the first driven gear is rotatably connected in the first shaft hole through the first rotating shaft, the second driven gear is rotatably connected in the second shaft hole through the second rotating shaft, the first clamp is connected to the first rotating shaft, the second clamp is connected to the second rotating shaft, the first driven gear is meshed with the second driven gear, the driving gear is meshed with the first driven gear, or is meshed with the second driven gear, or the middle gear, the first driven gear, and the second driven gear are meshed with each other, and the purpose of the meshing is to make the first driven gear and the second driven gear move towards or against each other.

[0028] The bracket used in this embodiment is a double-layer structure, specifically including a left frame plate 11 and a right frame plate 12. The left frame plate and the right frame plate are symmetrically arranged, and there is a certain distance between the left frame plate and the right frame plate. The driving shaft, the driving gear, the first driven gear, the second driven gear, the first clamping claw, the second clamping claw, the first rotating shaft, and the second rotating shaft are connected between the left frame plate and the right frame plate. The top height of the left frame plate and the right frame plate is slightly higher than the height of the first clamping claw and the second clamping claw. An arc groove 13 is arranged at the middle position of the top of the left frame plate and the right frame plate, and a fixing plate 14 passes under the left frame plate and the right frame plate. Such an arrangement can protect the driving shaft, the driving gear, the first driven gear, the second driven gear, the first rotating shaft, and the second rotating shaft, while preventing the above components from causing damage to the clamped object, and the arc groove can provide a certain blockage when the spherical object enters the clamping position to prevent the spherical object from rolling.

[0029] The rotating roller is arranged at the end of the driving shaft, specifically installed on the outside of the left frame plate and the right frame plate. According to different forms, one roller can be arranged on the outside of the left frame plate and the right frame plate, or one roller can be arranged on the outside of one of the left frame plate and the right frame plate. The specific decision is made according to other matching components.

[0030] The first clamping jaw includes a first left clamping jaw 51 and a first right clamping jaw 52, ​​and the second clamping jaw includes a second left clamping jaw 61 and a second right clamping jaw 62.

[0031] The first left clamp, the first right clamp, the second left clamp and the second right clamp have the same structure, and all have a claw handle 53, a claw body 54 and claw teeth 55. The claw body is in the shape of an arc plate, the claw handle is arranged at the bottom of the claw body, the claw body is connected to the first rotating shaft and / or the second rotating shaft, and the claw teeth are wave patterns arranged inside the claw body. By setting the claw teeth with wave patterns, the bite force of the claw body is increased, the friction force is increased, and the clamped object is prevented from falling off when clamping a spherical object or vegetable.

[0032] When the rollers are installed on both sides of the bracket, the rollers include an unlocking roller 71 and a locking roller 72. The locking roller is arranged at the left end of the driving shaft, and the unlocking roller is arranged at the right end of the driving shaft. Whether it is at the left end or the right end can be determined according to the on-site installation position.

[0033] To prevent the first clamping jaw and the second clamping jaw from being over-opened, the bracket further includes a baffle 14, one end of which is fixed to the upper part of the left frame plate or the right frame plate, and the other end of which extends toward the right frame plate or the left frame plate on the opposite side to block the movement of the first clamping jaw or the second clamping jaw. The baffle can also be connected to both the left frame plate and the right frame plate.

[0034] Example 2

[0035] The similarities between this embodiment and embodiment 1 are not described in detail, and the difference lies in the setting of the bracket.

[0036] In this embodiment, the bracket is set up using a single plate, and the driving shaft, driving gear, first driven gear, second driven gear, first clamp, second clamp, first rotating shaft, and second rotating shaft are set on the same side of the single plate, and the rotating roller can use a single rotating roller or a double rotating roller.

[0037] Example 3

[0038] This embodiment and the next embodiment mainly illustrate a conveying system equipped with an automatic clamping tool based on a conveyor belt as described in Embodiment 1 or Embodiment 2.

[0039] like Figure 1-6 As shown, a conveying system includes a conveyor belt 80 and an automatic clamping tool based on the conveyor belt as described in Example 1. The automatic clamping tool is fixed on the conveyor belt through a bracket. A locking frame 81, an unlocking frame 82, a locking bridge 90, and an unlocking bridge 91 are arranged on the side of the conveyor belt. The locking frame and the unlocking frame are arranged parallel to the conveyor belt. The locking bridge is arranged on the locking frame, and the unlocking bridge is arranged on the unlocking frame. The locking bridge and the unlocking bridge are arranged staggered relative to each other. The rotary roller is slidably connected to the locking bridge, and the rotary roller is slidably connected to the unlocking bridge. The locking frame and the unlocking frame are arranged above the plane of the conveyor belt in the direction of the diagonal.

[0040] The locking bridge has the same structure as the unlocking bridge, including a bridge plate 92, a connecting plate 93, a fixing bolt 94, and a spring 95. The connecting plate is arranged on the side of the bridge plate, and a fixing hole 96 is arranged on the connecting plate. One end of the fixing bolt is fixed to the locking frame or the unlocking frame, and the other end passes through the connecting hole to be connected to the connecting plate. The spring is sleeved on the outside of the fixing bolt and is arranged between the connecting plate and the locking frame or the unlocking frame.

[0041] In order to facilitate the roller to lock or unlock the bridge up and down, bending plates 97 are provided at both ends of the bridge plate.

[0042] The rotary rollers on the bracket recorded in this embodiment are set in a mode in which rotary rollers are set on both sides at the same time. Whether it is a double-board bracket in Example 1 or a single-board bracket in Example 2, as long as rotary rollers are set on both sides, it can be used.

[0043] When the conveyor belt moves to the right and the locking roller of the automatic clamping tool passes through the locking bridge, friction is generated between the locking roller and the locking bridge. The friction force causes the locking roller to rotate right (clockwise), and the locking roller drives the driving gear to rotate right, and the first driven gear meshing with the driving gear rotates left (counterclockwise), and the second driven gear meshing with the first driven gear rotates right (clockwise), and the first clamping jaw fixed on the first rotating shaft and the second clamping jaw fixed on the second rotating shaft rotate towards each other, thereby clamping the spherical vegetables.

[0044] When the conveyor belt continues to move to the right, the unlocking roller of the automatic clamping tool passes through the unlocking bridge, and friction is generated between the unlocking roller and the unlocking bridge. The friction force causes the unlocking roller to rotate left (counterclockwise), and the unlocking roller drives the driving gear to rotate left, and the first driven gear meshing with the driving gear rotates right (clockwise), and the second driven gear meshing with the first driven gear rotates left (counterclockwise), and the first clamping jaw fixed on the first rotating shaft and the second clamping jaw fixed on the second rotating shaft rotate in opposite directions, thereby unlocking the clamped spherical vegetables.

[0045] Example 4

[0046] The similarities between this embodiment and embodiment 3 are not repeated here. The difference lies in the setting of the bracket and the roller. This embodiment mainly describes the setting of the roller on one side. Regardless of whether it is the double-board bracket structure in embodiment 1 or the single-board bracket structure in embodiment 2, as long as the roller is set on one side, the solution described in this embodiment can be used.

[0047] In this embodiment, if Figure 4 As shown, the unlocking frame and the locking frame are arranged on the same side of the conveyor belt, and the unlocking frame and the locking frame are symmetrically arranged with the straight line formed by the operation of the rotary roller as the center line, one is arranged above the straight line of the operation of the rotary roller, and the other is arranged below the straight line of the operation of the rotary roller. The unlocking frame and the locking frame are fixedly connected by a connecting frame 83. When the rotary roller contacts the locking bridge, the rotary roller will rotate in one direction. When the rotary roller contacts the unlocking bridge, the rotary roller will rotate in the opposite direction of the previous rotation direction, thereby completing the locking and unlocking movements.

[0048] The above embodiments are only for illustrating the structural concept and features of the utility model, and their purpose is to enable ordinary technicians in the field to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the essence of the content of the utility model should be included in the protection scope of the utility model.
