DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the structural diagrams and specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] like Figure 1-Figure 3 As shown, the utility model provides an embodiment of a fully automatic chain plate conveyor type laser engraving machine, which is mainly composed of three functional systems: a conveying system, a loading system and a laser engraving machine. Among them, the conveying system adopts a chain plate conveyor belt, and the chain plate conveyor belt is composed of sprocket plates 1 linked to each other to form a closed circulation system, and the conveying motor 14 drives the sprocket 20 to drive the conveyor belt to operate. A flat mold 3 is installed on the chain plate conveyor belt, and the flat mold 3 circulates with the chain plate conveyor belt; the loading system is located at the upper part of the conveying system, including a hopper 12, a vertical brush rotating system and a horizontal brush rotating system. After the hopper 12 receives the product to be engraved, the vertical brush rotating system and the horizontal brush rotating system cooperate with each other to load the product to be engraved into the mold cavity of the flat mold 3; with the movement of the conveying system, the flat mold 3 filled with the product to be engraved moves to the bottom of the laser engraving machine 2, and the laser engraving machine 2 engraves on the surface of the product according to the control signal sent by the received electronic control system. The following will be described in detail in conjunction with the accompanying drawings.

[0025] First, the conveying system is fixed in the lower space of the conveyor body 13, and is composed of the following components: a closed chain structure composed of chain-plate conveyor belt sprocket plates 1 linked to each other, and the conveyor belt is driven by sprockets 20 distributed on both sides, and the teeth of the sprockets 20 are sequentially inserted into the gaps of the sprocket plates 1 to drive the chain-plate conveyor belt to operate; the number of sprockets 20 is at least two, and the sprocket 20 connected to the conveying motor 14 can be used as the driving wheel, and the sprocket on the other side can be used as the driven wheel, or the number of sprockets can be increased in the middle based on the length and span of the conveyor belt.

[0026] like Figure 3 As shown, the sprocket 20 is driven by the power output by the conveying motor 14. The conveying motor 14 is connected to the sprocket shaft 18 through the coupling 17, and the sprocket shaft 18 is fixedly connected to the sprocket 20 by a key connection. The gear teeth of the sprocket 20 are meshed with the chain 19, and the chain 19 is fixedly connected to the sprocket plate 1 by bolts. The output power of the conveying motor 14 drives the sprocket 20 to rotate through the coupling 17 and the sprocket shaft 18, and the sprocket 20 drives the chain 19 to move horizontally, thereby driving the sprocket plate 1 to move forward. In this embodiment, the conveying motor 14 is a reduction motor, and the speed can be adjusted at any time according to the loading conditions, etc.

[0027] like Figure 2 As shown, the flat mold 3 is fixed to the sprocket plate 1 by a fixing nut 15, and the flat mold 3 has a mold cavity adapted to the shape of different dosage forms, and the size and depth of the mold cavity are slightly larger than the corresponding dosage forms. The mold cavities are arranged in parallel both horizontally and vertically on the flat mold, and the flat molds 3 are arranged and connected to the outer surface of the sprocket plate 1; when the sprocket plate 1 is driven to move, the flat mold 3 moves with it. In this embodiment, the flat mold 3 is fixed to the sprocket plate 1 by a fixing nut 15 and moves with the sprocket plate 1. Of course, other detachable connection methods can also be adopted, so that the corresponding flat mold can be replaced according to the needs of different dosage forms to meet the engraving needs of other dosage forms.

[0028] The loading system is arranged on the upper part of the conveying system, such as Figure 1 and Figure 3 As shown, the loading system includes a hopper 12, a vertical brush rotation system and a horizontal brush rotation system. The hopper 12 is fixedly connected to the conveyor body 13. The width of the hopper 12 is slightly wider than the width of the flat mold 3. The side wall of the hopper 12 is connected to the bent part of the conveyor body 13 by welding or riveting. The lower edge of the hopper 12 is close to the upper surface of the flat mold 3, and the gap is smaller than the size of the product to be engraved, so as to ensure that the product to be engraved will not overflow from the hopper 12 space; the vertical brush 11 and the horizontal brush 5 are arranged above the flat mold 3 in the hopper 12 space, and the lower part of the brush bristles is in contact with the upper surface of the flat mold 3, so as to sweep the product to be engraved into the mold cavity of the flat mold.

[0029] The vertical brush rotation system is composed of a vertical brush 11, a vertical brush motor 6, a motor gear 7, a fixed gear shaft 8, a rotating gear 9 and a vertical brush gear 10. The vertical brush 11 is arranged upright relative to the chain plate conveyor belt. The vertical brush motor 6 is fixed on the hopper 12, and its output shaft is connected to the motor gear 7; the fixed gear shaft 8 is fixed on the hopper 12, and the rotating gear 9 is sleeved on the fixed gear shaft 8; the motor gear 7 and the rotating gear 9 are meshed; a planetary gear is connected to the outer sleeve of the central axis of the vertical brush 11, and the planetary gear is meshed with both the rotating gear 9 and the vertical brush gear 10. The output shaft of the vertical brush motor 6 rotates, driving the motor gear 7 to rotate, thereby driving the rotating gear 9 meshed with the motor gear 7 to rotate. After the rotating gear 9 rotates, it drives the planetary gear of the central axis of the vertical brush 11 to rotate, and further drives the vertical brush gear 10 to rotate, so that the vertical brush 11 rotates while revolving around the fixed gear shaft 8. The movement mode of the vertical brush 11 revolving and rotating can increase the cleaning area.

[0030] At the rear of the chain plate conveyor belt in the running direction, a horizontal brush rotation system is provided, which includes a horizontal brush 5 and a horizontal brush motor 16. The horizontal brush 5 is provided at the rear of the vertical brush 11 and is arranged horizontally perpendicular to the running direction of the chain plate conveyor belt. The rotation direction of the horizontal brush 5 is opposite to the running direction of the chain plate conveyor belt. Figure 1 As shown, in this embodiment, the flat plate mold 3 on the upper part of the chain plate conveyor belt moves horizontally from right to left, and the horizontal brush 5 rotates counterclockwise.

[0031] The working principle of the charging system is:

[0032] Pour the product to be engraved into the space of the hopper 12, and the product falls onto the flat plate mold 3 on the surface of the chain plate conveyor belt, and moves forward with the flat plate mold 3;

[0033] When the flat mold 3 moves to the position of the vertical brush 11, the vertical brush rotating system performs revolution and rotation to brush the product into the mold cavity of the flat mold 3 (product 4 in the mold cavity);

[0034] When the flat mold 3 continues to run to the position of the horizontal brush 5, the horizontal brush 5 rotates counterclockwise to sweep the products left outside the mold cavity of the flat mold 3 back to the vertical brush 11. The vertical brush 11 revolves and rotates to continue filling the swept products into the empty mold cavity.

[0035] If there are still products left behind that run to the position of the horizontal brush 5 , repeat the operation of the previous step until all the products to be engraved are loaded into the mold cavity of the flat mold 3 .

[0036] The conveying motor 14 of the conveying system, the vertical brush motor 6 and the horizontal brush motor 16 of the loading system are respectively connected to the electronic control system through cables, and receive control signals sent by the electronic control system, and the control signals can be set and adjusted through the touch screen of the electronic control system.

[0037] like Figure 1 and Figure 2 As shown, the laser engraving machine 2 is arranged at the rear end of the running direction of the flat-plate mold 3, after the loading system. When the loading system loads the product to be engraved into the mold cavity of the flat-plate mold 3, the position of the product in the mold cavity is relatively fixed. As the flat-plate mold 3 runs to the bottom of the laser engraving machine 2, the laser engraving machine 2 performs laser engraving on the surface of the product in the mold cavity. The engraving content can be set in advance through the touch screen of the electronic control system, and can also be edited. Different identification contents can be designed according to different needs, such as company logos or company names. Since the product to be engraved is fixed in the mold cavity of the flat-plate mold 3, the flat-plate mold 3 moves horizontally at a uniform speed at the laser engraving machine 2, and unqualified products such as blurred handwriting will not appear during engraving.

[0038] The product engraved by the laser engraving machine is continuously conveyed forward along with the flat-plate mold 3. When the product reaches the turning point of the chain plate conveyor belt, the flat-plate mold 3 turns over along with the sprocket plate 1, and the finished product is poured into the finished product hopper 21, thereby completing the finished product recovery.

[0039] like Figure 4 As shown, the utility model provides an embodiment of a flat mold structure. The surface of the flat mold 3 is processed into a mold cavity according to the shape and size of different dosage forms of products. The depth and size of the mold cavity are slightly larger than the size of the product to be processed, and the shape is the same as the shape of the spray product. Each mold cavity is used to accommodate a grain of the product to be sprayed. The arrangement principle of the mold cavity is to maximize the use of the surface area of ​​the flat mold 3 as much as possible. The spacing size between the mold cavities is smaller than the product appearance size while meeting the processing requirements such as the necessary strength of the mold cavity wall, so as to reduce the number of products trapped in the spacing space between the mold cavities. In this embodiment, the mold cavities are aligned with each other in parallel and transverse directions in a determinant manner on the surface of the flat mold 3, thereby maximizing the use of the surface area of ​​the flat mold 3. In order to facilitate the fixation and disassembly of the sprocket plate 1, a through hole is opened on the edge of the flat mold 3, and the fixing nut 15 passes through the through hole to connect the flat mold 3 and the sprocket plate 1.

[0040] The utility model sweeps the product to be engraved into the mold cavity of the flat mold through the revolution and rotation of the vertical brush, sweeps the missed product to be engraved back to the position of the vertical brush through the rotation of the horizontal brush, and repeats the cycle of cleaning to ensure that all the products to be engraved enter the mold cavity. When the product to be engraved in the mold cavity passes through the laser engraving machine steadily and evenly, the laser engraving machine laser engraves logos and text on its surface, and the engraving process can be carried out uninterruptedly at high speed, and the efficiency is greatly improved. Since no human participation is required, not only the labor intensity of the operator is reduced, but also the risk of contamination of the product by human participation is reduced.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
