DETAILED DESCRIPTION

[0026] See also Figure 1-Figure 2In an embodiment of the present invention, a double-lifting weighing device includes a roller conveying assembly 1, wherein a plurality of weighing assemblies 2 and a lifting assembly 3 are arranged below the roller conveying assembly 1, wherein the weighing assembly 2 is composed of a weighing cylinder, a first synchronous lifter, a weighing module and a weighing support plate; the lifting assembly 3 is composed of a lifting cylinder, a second synchronous lifter and a lifting support plate, wherein a plurality of weighing cylinders are synchronously operated through the first synchronous lifter, the weighing support plate is assembled and connected to the output end of the weighing cylinder, and the weight change on the total support plate is sensed through the weighing module, and the plurality of lifting cylinders can also be synchronously operated through the second synchronous lifter. The synchronous operation is controlled by a descender, and the output end of the jacking cylinder is assembled and connected with a jacking support plate. Preferably, the jacking support plate and the weighing support plate are both installed with anti-skid components 5 for preventing the pallet from sliding relative to the pallet when the pallet is placed thereon. The weighing component 2 and the jacking component 3 are symmetrically arranged in multiple groups under the roller conveying component 1. The roller conveying component 1 is composed of a frame, a roller, a driving mechanism, legs and side guards, etc. The frame is equipped with legs and side guards, and multiple groups of rollers are rotatably connected to the frame, and the multiple groups of rollers are synchronously transmitted and connected by a driving mechanism. The driving mechanism The mechanism can be composed of a sprocket chain and a driving motor, and multiple rollers rotate synchronously through the cooperation of the sprocket chain, and the output end of a driving motor drives the roller to rotate through the cooperation of the sprocket chain; a clamping assembly 4 is provided below the input side of the roller conveying assembly 1, wherein the roller conveying assembly 1 is used to convey pallets, and the materials are placed on the pallets and conveyed through the roller conveying assembly 1. After the materials are conveyed over the clamping assembly 4, the output end of the clamping assembly 4 pushes the pallet to the top of the weighing assembly 2 and the lifting assembly 3. At this time, the lifting assembly 3 is first used to drive its output end to lift the pallet upward. The output end of the weighing component 2 is moved upwards to support the pallet, and the output end of the lifting component 3 is moved downwards to separate from the pallet. At this time, the pallet is placed on the weighing component 2 for weighing. After weighing, the weighing component 2 can drive the pallet downwards and gradually place it on the roller conveying component 1 for continued conveying, and continue weighing after the next pallet arrives. In this way, through the cooperation of the weighing component 2 and the lifting component 3, the pallet can be lifted and weighed separately, which effectively avoids the problem of inaccurate weighing and can also avoid damage to the roller and the weighing module when the goods are directly placed on the pallet.Moreover, during use, through the cooperation of the anti-skid component 5, when the output end of the jacking component 3 rises to contact the bottom of the pallet and pushes the pallet upward, the anti-skid component 5 on the jacking component 3 and the pallet are attached to and fixed to the pallet, thereby avoiding the risk of the pallet slipping. When the output end of the weighing component 2 moves upward and contacts the bottom of the pallet, similarly, the anti-skid component 5 on the weighing component 2 can also be adsorbed and fixed to the bottom of the pallet. When the output end of the jacking component 3 moves downward, the adsorption of the anti-skid component 5 and the pallet thereon can be gradually relaxed, thereby driving the anti-skid component 5 to be retracted, which is convenient for the weighing and use of the pallet. After the output end of the weighing component 2 weighs and drives the pallet to descend onto the roller conveying component 1, the output end of the weighing component 2 can be continuously retracted to release the anti-skid component 5 on the weighing component 2 from the adsorption of the pallet.

[0027] Preferably, Figure 3 As shown, the clamping assembly 4 includes a clamping cylinder 41, a connecting rod 42 is provided on the output end of the clamping cylinder 41 for transmission connection, the clamping cylinder 41 is rotatably mounted on one side leg of the roller conveying assembly 1 through a housing, a push plate 44 is rotatably provided on one end of the connecting rod 42 away from the clamping cylinder 41, and a shaft support 43 for connecting to the roller conveying assembly 1 is rotatably provided on one side of the push plate 44. After the clamping cylinder 41 is started, the clamping cylinder 41 pushes the pallet to the top of the weighing assembly 2 and the lifting assembly 3 and reaches the designated position.

[0028] like Figure 4 As shown, the anti-skid assembly 5 includes a pad 51, which is assembled and connected to the weighing support plate of the weighing assembly 2 or the lifting support plate of the lifting assembly 3 by bolts, and a pad ring 54 is elastically connected to the side of the pad 51 away from the weighing support plate or the lifting support plate through a telescopic rod 53, and a piston column 52 is connected to the end face of the pad 51, and the piston column 52 is matched and connected to the inner circle of the pad ring 54. In this embodiment, the friction force of the pad ring 54 can be used to avoid the risk of the pallet sliding, and it is safer and more stable when the weighing assembly 2 or the lifting assembly 3 lifts or puts down the pallet.

[0029] Among them, Figure 5 As shown, the surface of the gasket 54 away from the telescopic rod 53 is fitted with a rubber or silicone rubber pad 5401, the gasket 54 and the rubber pad 5401 are concentric and overlapping annular structures, and the telescopic rod 53 is provided with a plurality of gaskets distributed in an annular array with the end face center of the gasket block 51 as the origin. In this way, friction can be maintained and the tray can be supported stably and conveniently.

[0030] Furthermore, the telescopic rod 53 includes a sleeve 5301 and a sliding rod 5302 that are connected in a sliding fit, a compression spring is connected between the sleeve 5301 and the sliding rod 5302, and an assembly ring 5303 is fixedly sleeved on the outer periphery of the end of the sleeve 5301 away from the sliding rod 5302. This part of the arrangement can play a buffering role during contact, avoiding rigid collisions that affect the use of the weighing module (weight sensor). In addition, the movement direction of this part of the structure is fixed, and there will be no lateral movement. The support for the tray is also relatively stable and is not prone to tilting.

[0031] like Figure 4-Figure 8 As shown, a plurality of assembly holes 5102 matching the size of the assembly ring 5303 are embedded in the periphery of the end surface of the cushion block 51, and the assembly ring 5303 is assembled and connected in the assembly holes 5102 by bolts.

[0032] A sliding hole 5101 is embedded in the center of the cushion block 51, and the piston column 52 includes a column 5201 slidably connected in the sliding hole 5101, and the column 5201 is slidably adapted with the gasket 54 and the inner ring of the rubber pad 5401. An air vent 5202 is embedded in the end surface of the column 5201, and a plurality of first air guide holes 5203 penetrating the side wall of the column 5201 are connected in the air vent 5202, and the plurality of columns 5201 are located at the edge of the same circular surface parallel to the end surface of the column 5201. Through the above arrangement, the column 5201 can be used as a piston. When the rubber pad 5401 on the gasket 54 contacts the pallet, the gravity of the pallet can compress the relative distance between the sleeve 5301 and the sliding rod 5302, so that the gasket 54 moves toward the cushion block 51. Originally, a space facing the pallet is formed between the end face of the column 5201 and the inner circle of the gasket 54. As the gasket 54 and the rubber pad 5401 slide on the periphery of the column 5201, this space is compressed, and the gas flows out through the first air guide hole 5203. Preferably, a one-way valve can be embedded in the first air guide hole 5203. In this way, as the pallet moves the gasket 54 to the opening where the first air guide hole 5203 passes through the outer side of the column 5201, the space formed between the column 5201 and the gasket 54 is exhausted, and an adsorbable negative pressure state is formed, thereby improving the stability of the tray placement.

[0033] In order to facilitate the detachment of the pallet, a plurality of second air guide holes 5204 connected to the air vents 5202 are embedded on the outer side of the column 5201 and located away from the gasket 54. The sliding hole 5101 is a cylindrical blind hole with a contracted opening. An anti-detachment flange 5205 is fixedly provided at the outer end of the column 5201. The anti-detachment flange 5205 is slidably adapted to the sliding hole 5101, and the outer diameter of the anti-detachment flange 5205 is larger than the size of the opening of the sliding hole 5101. In this way, when in contact, the air in the space is discharged. When the weighing component 2 or the lifting component 3 drives the cushion block 51 away from the pallet, because the gasket 54 and the column The space composed of the column 5201 is negatively adsorbed by pressure. At this time, the cushion block 51 is pulled to slide around the column 5201, and the second air hole 5204 is originally located in the sliding hole 5101. Preferably, the edge of the sliding hole 5101 is inlaid with a rubber layer for sealing. When the cushion block 51 slides relative to the surface of the column 5201, the second air hole 5204 is exposed, so that the air hole 5202 can breathe through the second air hole 5204. After the negative pressure space composed of the column 5201 and the gasket 54 takes in air, the adsorption effect is no longer produced, so that the telescopic rod 53 can be used to pull the gasket 54 away from the tray and gradually restore it to its original position for use after the next contact. Such a setting can facilitate detachment after adsorption and automatic resetting. Normally, due to gravity, the anti-detachment flange 5205 at the lower end of the column 5201 is partially located at the bottom of the sliding hole 5101, and the second air guide hole 5204 is blocked by the inner edge of the opening of the sliding hole 5101 and is not breathable. When it is necessary to pull away from the pallet, the pallet is either lifted by the weighing component 2 or supported on the roller conveying component 1, and the position will not move, so the pad 51 can be pulled relatively moved, and then the air vent 5202 is connected to balance the pressure, thereby facilitating detachment from the pallet.
