This spiral feeding device adopts a double-layer spiral structure, in which the upper spiral structure is used for material control and the lower spiral structure is used for feeding, so as to realize the control of material supply. However, this prior art also has the following defects:

[0003] 1. When the material is between the two screws, the motors of the upper and lower spiral structures cannot rotate synchronously. At this time, the speed difference between the two motors will squeeze the material, which may cause the material to deform or damage.

[0004] 2. The materials will be entangled in the screw, causing the whole mass of materials to fall into the hopper together when the materials are discharged from the tail of the lower screw, causing the actual weighing weight to exceed the target weight, the combined weighing pass rate to be low, and the weighing speed of the whole machine to be slow.

[0005] 3. Due to the difficulty in making screws and the diversity of their sizes, screws are not conducive to mass production. For different materials, screws of different sizes are required to match the feeding, and the equipment cost is high. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] like Figure 1 and Figure 2 The combined feeding device shown includes a mounting frame, a material trough, a material control motor, a material control screw, a feeding motor, a feeding belt and a plurality of feeding baffles. The material trough is fixed to the mounting frame, the material control screw is installed at the upper end of the material trough, and one end of the material control screw is connected to the material control motor; the feeding belt is installed in the material trough through a feeding wheel, and the feeding belt is located below the material control screw, one of the feeding wheels is connected to the feeding motor through a transmission mechanism, and a plurality of feeding baffles are fixed to the outer surface of the feeding belt.

[0027] Specifically, multiple feeding baffles are fixed to the outer surface of the feeding belt by hot-melt, and the feeding belt is driven by a feeding motor to form a lower feeding structure, which replaces the existing lower spiral structure, thereby avoiding squeezing of the material and avoiding deformation or damage of the material. At the same time, the lower feeding structure composed of the feeding belt and feeding baffles will not allow the material to be entangled, thereby improving the weighing pass rate. At the same time, the feeding structure composed of the feeding belt has a fast feeding speed. Figure 2 As shown, during the working process, the feeding motor drives the feeding baffle to rotate in the direction of the arrow through the feeding belt, thereby pushing the material in the trough to push the material from the trough to the subsequent hopper in an orderly manner. It can be seen that the feeding motor can adjust the rotation speed of the feeding baffle according to the material, so that the feeding baffle can quickly push the material.

[0028] The feeding wheel includes a feeding driving wheel and a feeding driven wheel, which are respectively installed at two ends of the material trough, and the two ends of the feeding belt are respectively connected to the feeding driving wheel and the feeding driven wheel; the feeding motor is installed on the mounting frame, and the power output shaft of the feeding motor is connected to the feeding driving wheel through a transmission mechanism. This structure is simple, easy to install, and ensures the running stability of the feeding belt.

[0029] The transmission mechanism includes a transmission belt, a transmission driving wheel and a transmission driven wheel. The transmission driving wheel is installed on the power output shaft of the feeding motor. The transmission driven wheel is connected to the feeding driving wheel through the transmission shaft. The two ends of the transmission belt are respectively connected to the transmission driving wheel and the transmission driven wheel. The use of this transmission mechanism ensures stable transmission of power, that is, it ensures that the feeding motor can stably drive the feeding belt to rotate, and has high reliability.

[0030] A plurality of the feeding baffles, feeding belts and troughs form feeding cavities of different volumes. Specifically, the distances between the feeding baffles can be set to different sizes according to the materials, thereby forming feeding cavities of different sizes and volumes to meet the needs of different materials and further avoid damaging the materials.

[0031] The feeding baffle is fixed to the outer surface of the feeding belt by hot melting. Figure 3As shown, the feed baffle includes a substrate, a main board and a gradient plate, and the substrate, the main board and the gradient plate are integrally formed. The substrate is fixed to the feed belt, one end of the main board is connected to the substrate, and the other end of the main board is connected to the inner end of the gradient plate (i.e., the end facing the feed belt), and the thickness of the gradient plate gradually decreases from the inner end to the outer end (i.e., the end away from the feed belt). The feed baffle and the feed belt are fixed by hot melting, and this structure is firm and stable, thereby ensuring the working performance of the baffle. At the same time, the feed baffle is mainly composed of a substrate, a main board and a gradient plate, and this structure is simple and easy to manufacture. The feed baffle is connected to the feed belt through the substrate, ensuring that there is a sufficient contact surface between the feed baffle and the feed belt, and further ensuring the firmness of the feed belt when it is fixed. The thickness of the outer end of the feed baffle gradually decreases, which can further avoid damage to the material.

[0032] The axis of the material control screw is parallel to the feeding plane of the feeding belt. The parallel arrangement can ensure that the material is fed while further avoiding squeezing of the material to avoid deformation or damage of the material.
