Description

Online weighing device of fruit vegetables

Technical Field

The utility model relates to a fruit vegetables sorting unit specifically is an online weighing device when fruit vegetables are hierarchical.

Background

The automatic fruit and vegetable sorting device is an important ring for fruit and vegetable sorting according to weight classification, an existing full-automatic fruit and vegetable sorting machine is mature, for example, an online dynamic weighing device disclosed in the publication No. CN201034713Y, a weighing driving shaft, weighing supporting claws, a weight sensor, a sensor support, a weighing driven shaft and a weighing chain are arranged above a weighing supporting frame, chain wheel teeth matched with the weighing chain are respectively arranged on the weighing driving shaft and the weighing driven shaft, the weighing driving shaft and the weighing driven shaft are respectively arranged on two sides above the weighing supporting frame and are meshed with the weighing chain to be connected, the weighing supporting claws are assembled on the weighing chain, and the weight sensor is arranged on the weighing supporting frame and is arranged below the weighing chain. However, the patent has the following disadvantages: firstly, the transmission mode of the chain and the chain wheel is heavy and has high noise, meanwhile, the chain can be loosened after long-time running, sliding teeth can occur, and the chain needs lubricating oil for lubrication, so that fruit and vegetable pollution can be caused; secondly, the weighing support claw is usually assembled on a pin shaft of the weighing chain, or a special-shaped chain with the pin shaft extending out of a chain plate needs to be customized, or an auxiliary pin shaft for assembling the weighing support claw is welded outside the chain plate of the chain, so that the weighing support claw is high in difficulty and cost and is not easy to install and disassemble; and thirdly, a tensioning wheel is generally adopted for tensioning the chain, the tensioning wheel is generally arranged below the rack, and a guard plate below the rack needs to be detached during adjustment, so that time and labor are wasted.

Disclosure of Invention

In order to overcome one of the above technical defects or technical defects of the prior art, the utility model discloses a following technical scheme:

the utility model provides an online weighing device of fruit vegetables, includes the frame, sets up driving shaft, driven shaft at frame both ends, its characterized in that: at least a pair of driving synchronous belt wheels and a pair of driven synchronous belt wheels are respectively pivoted on the driving shaft and the driven shaft, an arch frame is fixedly arranged at the top of the frame between the driving synchronous belt wheels and the driven synchronous belt wheels on the same straight line, synchronous belts are respectively wound on the driving synchronous belt wheels and the driven synchronous belt wheels on the same straight line and slide on the upper surface of the arch frame, a plurality of weighing support claws are uniformly arranged on the synchronous belts, a weighing support is arranged on the frame between the arch frames, and a weight sensor is arranged below the weighing support. The utility model discloses changing the chain into synchronous belt drive, synchronous belt is littleer than chain drive sound, and is cheaper, is difficult to smooth tooth, therefore need not lubricated pollution-free.

Furthermore, a plurality of the weighing support claws are evenly clamped on the two synchronous belts.

Further, a carriage is mounted on the machine frame, the driving shaft or the driven shaft is fixedly arranged on the carriage, a sleeve with the axial direction in the front-back direction is fixedly arranged on the carriage, a spring is pressed in the sleeve, the outer end of the spring abuts against an adjusting bolt, and the adjusting bolt is fixedly connected with the machine frame.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a partially enlarged view of fig. 1.

Detailed Description

The utility model discloses it is further explained below to combine the figure, need to explain in advance that a plurality of weighs in figure 1 holds in the palm the claw should evenly the joint in hold-in range round, for the more clear performance, only shows 2 in figure 1 and weighs and hold in the palm the claw, does not show the utility model discloses only have 2 to weigh to hold in the palm the claw between every pair hold-in range.

Embodiment 1, as shown in fig. 1-2 a fruit vegetables online weighing device, including frame 1, set up driving shaft 2, driven shaft 3 at frame 1 both ends, at least a pair of driving synchronous pulley 4 and a pair of driven synchronous pulley 5 are pivoted respectively on driving shaft 2 and the driven shaft 3, lie in same straight line between driving synchronous pulley 4 and the driven synchronous pulley 5 the top of frame 1 sets firmly an arch frame 6 respectively, and hold-in range 7 is around establishing respectively on being located same straight line driving synchronous pulley 4 and the driven synchronous pulley 5 and slide the arch frame 6 upper surface, two a plurality of support claw 8 that weighs is evenly blocked on the hold-in range 7. A weighing support 9 is arranged on the frame 1 between the two arches 6, and a weight sensor is arranged below the weighing support 9.

Embodiment 2 is otherwise the same as embodiment 1, except that a carriage 13 is mounted on the frame 1, the driving shaft 2 or the driven shaft 3 is fixedly mounted on the carriage 13, a sleeve 14 whose axial direction is the front-back direction is fixedly mounted on the carriage 13, a spring is pressed in the sleeve 14, the outer end of the spring abuts against an adjusting bolt 15, and the adjusting bolt 15 is fixedly connected with the frame 1. The embodiment changes the tensioning wheel tensioning into the spring dynamic tensioning, does not need frequent adjustment, and is more convenient to adjust and easy to operate.

Compared with the prior art, the utility model discloses there is the outstanding technological effect in following several points:

firstly, chain transmission is changed into synchronous belt transmission, and the synchronous belt has smaller sound than the chain transmission; the chain has a lengthening rate, and can loosen after a long time, and sliding teeth can occur; the synchronous belt is not easy to have sliding teeth. And the replacement of the timing belt is cheaper than a chain and does not require lubrication and therefore is pollution-free.

Secondly, the chain transmission in the prior art is to use a chain roller shaft to drive the weighing supporting claw, and the utility model adopts the clamping connection, so that the disassembly and the installation are easier;

and secondly, the tensioning mode is positioned above the rack, so that the operation of workers is facilitated.

Other working principles are not substantially different from the existing on-line weighing device, and therefore, the description is omitted.
