Description

Technical Field

[0001] The invention relates to a feeding mechanism, in particular to a feeding mechanism capable of realizing automatic turning over of materials. Background Art

[0002] When producing certain products (such as ice cream plates, convenient chopsticks, etc.), it is often necessary to process (such as spraying, disinfection, etc.) or inspect (such as appearance inspection, quality inspection, etc.) the upper and lower surfaces. In this way, the workpiece needs to be flipped 180 degrees before the above operations can be performed. In order to achieve the above purpose, a chain conveyor mechanism is generally used to convey the product. During the conveying process, the flipping mechanism set in the chain conveyor mechanism will drive the product to flip 180 degrees. The overall structure of this mechanism is complex and the cost is relatively high. More importantly, due to the design defects of the flipping mechanism, the product cannot be guaranteed to be flipped 100%, which may cause the subsequent operations to fail to be completed effectively. Therefore, a method or device that can solve the above problems is now needed. Summary of the invention

[0003] The present invention aims to solve the above-mentioned deficiencies in the prior art and proposes a feeding mechanism which has a simple structure, ingenious design, smooth and reliable operation and can ensure that the material can be automatically turned over during transportation.

[0004] The technical solution of the present invention is: a feeding mechanism that can realize automatic flipping of materials, characterized in that: the feeding mechanism includes two feeding toothed discs 1 that are parallel to each other and connected to each other, the feeding toothed discs 1 can rotate under the drive of a motor, and a pair of auxiliary discs 2 are arranged between the two feeding toothed discs 1, and a plurality of feeding teeth 3 evenly distributed in the circumferential direction are arranged on the outer circumference of the feeding toothed disc 1, and a protrusion is arranged on the side of the feeding tooth 3, and the longitudinal end face of the protrusion is in the shape of a right-angled triangle, and the top edge 4 of the protrusion is at a right angle to the side edge 5 of the feeding tooth 3, and the junction between the top edge 4 and the hypotenuse 6 is a rounded transition, and there is a feeding gap 7 between adjacent feeding teeth 3, and a step 8 is arranged on the auxiliary disc 2, and the step 8 is located between the eleven o'clock direction and the twelve o'clock direction. The width of the top edge 4 is less than half of the width of the conveyed workpiece 9, and the outer circumference of the auxiliary disc 2 located between the nine o'clock direction and the step 8 is kept flush with the top edge 4 on the feeding tooth 3.

[0005] Compared with the prior art, the present invention has the following advantages:

[0006] This type of feeding structure that can realize automatic material flipping has a simple structure, ingenious design, and reasonable layout. It designs a special disc transmission structure to solve the problems existing in the traditional material conveying and flipping structure during the working process. It uses the protrusion on the feeding tooth and the auxiliary disk to jointly support the workpiece, and uses the special structure on the protrusion and the auxiliary disk (the width of the top edge on the protrusion is less than half of the width of the conveyed workpiece, the top edge and the bevel edge are smoothly rounded, and steps are set at special positions of the auxiliary disk) to allow the workpiece to automatically flip when it moves to the area between eleven o'clock and twelve o'clock on the feeding tooth disk. Its flipping operation can be completed automatically without human intervention, which can save a lot of human resources. Moreover, it uses the method of changing the support area to realize the flipping of the workpiece (which can be understood as passive). The whole process is smooth and reliable, and will not cause missed flipping due to the failure of the traditional active flipping mechanism. In addition, its manufacturing process is simple and the manufacturing cost is low. Therefore, it can be said that it has many advantages and is particularly suitable for promotion and application in this field. Its market prospects are very broad. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The specific implementation of the present invention will be described below with reference to the accompanying drawings. Figures 1 to 4 As shown: a feeding mechanism capable of realizing automatic material flipping, comprising two feeding toothed discs 1 which are parallel to each other and connected to each other, the feeding toothed discs 1 being capable of rotating under the drive of a motor, a pair of auxiliary discs 2 being arranged between the two feeding toothed discs 1, a plurality of feeding teeth 3 uniformly distributed in the circumferential direction being arranged on the outer circumference of the feeding toothed disc 1, a protrusion being arranged on the side surface of the feeding tooth 3, a longitudinal end surface of the protrusion being in the shape of a right-angled triangle, and a top edge 4 of the protrusion being at a right angle to a side edge 5 of the feeding tooth 3, and a rounded transition being formed at the junction of the top edge 4 and the hypotenuse 6, and a feeding gap 7 being formed between adjacent feeding teeth 3, a step 8 being arranged on the auxiliary disc 2, the step 8 being located between the eleven o'clock direction and the twelve o'clock direction, the width of the top edge 4 being less than one-half of the width of the conveyed workpiece 9, and the outer circumference of the auxiliary disc 2 located between the nine o'clock direction and the step 8 being kept flush with the top edge 4 on the feeding tooth 3.

[0012] The working process of the feeding mechanism capable of realizing automatic material turning of the embodiment of the present invention is as follows: an automatic feeding machine is arranged at the nine o'clock direction of the feeding toothed disc 1, and an automatic unloading machine is arranged in the tangential direction of the feeding toothed disc 1. When working, the automatic feeding machine feeds the workpiece 9 ( Figure 2 In the example of convenient chopsticks, the workpieces 9 are fed into the feeding mechanism one by one according to a certain rhythm. Each workpiece 9 corresponds to a feeding tooth 3. During the movement between 9 o'clock and 11 o'clock, the side surface of the workpiece 9 contacts the side surface of the feeding tooth 3, and the bottom surface of the workpiece 9 contacts the top edge 4 of the protrusion and the outer circumference of the auxiliary disk 2 at the same time, and is supported by them.

[0013] When the workpiece 9 is transported to the position between the 11 o'clock and 12 o'clock directions, since there is a step 8 in this area, when the workpiece 9 moves to the step 8, the workpiece 9 will lose the support of the auxiliary plate 2, and only the top edge 4 of the protrusion will support it. At this time, the workpiece 9 has basically returned to a horizontal state, and since the width of the top edge 4 is less than half of the width of the workpiece 9, in other words, the center of the workpiece 9 is not within the support range of the top edge 4, so as the movement proceeds, the workpiece 9 will definitely fall down from the top edge 4;

[0014] Since there is a smooth rounded transition between the top edge 4 and the beveled edge 6, the workpiece 9 will smoothly flip down from the edge of the top edge 4 and fall directly into the feeding gap 7 below. At this time, the workpiece 9 flips 180 degrees, becomes a bottom-facing posture, and continues to move forward driven by the feeding toothed disc 1 until it is taken away by the automatic unloading machine set in the tangential direction of the feeding toothed disc 1. That is to say, the workpiece 9 with two sides A and B, after entering this mechanism through the automatic loader, will flip from the state where the A side is facing up to the state where the B side is facing up, and enter the automatic unloading machine with the B side facing up, that is, the workpiece 9 realizes a 180-degree flipping operation in this mechanism.
