DETAILED DESCRIPTION

[0025] 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.

[0026] like Figure 1 As shown, the utility model provides an embodiment of a fully automatic mode-changing inkjet printer, which includes a feeding system, a material guiding system, a rotary mold, a inkjet printer, a material receiving system and an electronic control system, wherein the feeding system is used to centrally receive products to be sprayed, such as soft capsules, hard capsules or tablets, and feed them into the material guiding system in an orderly manner; the material guiding system further feeds the products to be sprayed into the mold cavity of the rotary mold, and as the rotary mold rotates, the products in the mold cavity are sent to the inkjet printer, and the inkjet printer sprays corresponding marks according to the signals received from the electronic control system; the products that have been sprayed fall into the material receiving system as the rotary mold rotates for finished product recovery. The following will be described in detail in conjunction with the accompanying drawings.

[0027] like Figure 1 and Figure 2As shown, the frame 1 is the main structure for accommodating various systems and components, and the frame is made of profiles or stainless steel. The feeding system in this embodiment is a hopper 9, and the hopper 9 is arranged at the top of the frame 1. The hopper 9 adopts a funnel shape with a large top and a small bottom. Due to the large opening, it can receive a large number of products to be sprayed. The received products move downward under the action of gravity and enter the lower material guide system in a controllable and orderly manner through the gradually shrinking outlet of the hopper 9. The feeding system such as the hopper 9 can simply and efficiently receive a large number of products, and the number of products entering the lower material guide system is controllable, so as to avoid product accumulation in the material guide system and affect the material distribution of the material guide system. At the same time, a variety of methods can be used to achieve the product feeding into the hopper: for example, the hopper 9 can be connected to an inclined conveyor belt arranged outside the frame 1, the conveyor belt is connected to a pulley, the motor drives the pulley, the rotation of the pulley drives the conveyor belt to circulate, the product to be sprayed is placed on the conveyor belt and is brought from the bottom to the top of the hopper 9 as the conveyor belt moves, due to the inertia, the product continues to move away from the conveyor belt at the bend above the conveyor belt and falls into the receiving port of the hopper 9 below, thereby realizing the operation of automatically feeding the product into the hopper 9; for another example, the conveyor belt can also be equipped with a conveyor bucket on the transmission chain, the product is placed in the conveyor bucket, the conveyor bucket drives the transmission chain from bottom to top with the motor drive, and when the conveyor bucket is brought to the top of the hopper 9, as the conveyor chain moves downward, the conveyor bucket tilts and dumps the product in the bucket into the hopper 9. Of course, the worker can also directly dump the product to be sprayed into the hopper 9.

[0028] A material guide system is provided below the hopper 9, and the material guide system consists of a vibration hopper 8, a vibrator 10, and a material guide plate 7. The vibration hopper 8 is located below the hopper 9, and the product in the hopper 9 falls into the vibration hopper 8 through the outlet at the bottom of the hopper 9 under the action of gravity. The vibration hopper 8 is connected to the vibrator 10. Under the vibration of the vibrator 10, the product rotates or swings in the vibration hopper 8. When the product reaches the position of the material guide plate 7, it sequentially enters several separated channels of the material guide plate 7 and moves downward along the channel. The material guide plate 7 is provided with at least one or more channels, and the end of the channel is correspondingly connected to the mold cavity of the rotary mold 4, and the number of mold cavities is equal to the number of channels. When the product reaches the end of the channel of the material guide plate 7, it enters the mold cavity of the rotary mold 4 connected to one end of the channel, which is called the product in the mold cavity 20, thereby completing the material guide activity.

[0029] The rotary mold 4 is connected to the transmission shaft 5 through the pressing plate 3, and the transmission shaft 5 is connected to the rotary mold motor 11. The rotary mold motor 11 drives the transmission shaft 5 to rotate, and then drives the rotary mold 4 to rotate. The rotary mold motor 11 is fixed on the motor base 6, and the motor base 6 is connected to the fixing frame 12 by bolts. In this embodiment, the rotary mold motor 11 adopts a stepping motor to convert the input pulse signal into a corresponding angular displacement. The rotary mold motor 11 is connected to the electronic control system 19, receives the pulse signal transmitted by the electronic control system 19, drives the transmission shaft 5 to rotate, and then drives the rotary mold 4 to rotate a corresponding angle. When the product 20 in the mold cavity rotates to the bottom of the inkjet printer 16 with the rotary mold 4, the inkjet printer 16 prints ink on the surface of the product according to the pre-set content based on the signal sent by the electronic control system 19.

[0030] In this embodiment, the rotary mold 4 is detachably connected to the transmission shaft 5 through the pressing plate 3. The rotary mold 4 can also be connected to the transmission shaft 5 through other detachable connection methods, such as bolt connection, sleeve connection, etc. The detachable connection method is used to facilitate the replacement of different rotary molds, thereby meeting the needs of inkjet printing of products to be printed with different shapes and sizes.

[0031] The electronic control system 19 sets the time of the pulse signal, thereby controlling the angle and time of rotation of the rotary mold motor 11. By intermittently rotating the rotary mold 4, the inkjet printer 16 completes the inkjet printing of the product 20 in the mold cavity during the time when the rotary mold 4 stops rotating.

[0032] like Figure 2 As shown, the position of the inkjet printer 16 is adjustable: the inkjet printer 16 includes an up-down adjustment mechanism 17 and a left-right adjustment mechanism 18. The position of the inkjet printer 16 is adjusted vertically by the up-down adjustment mechanism 17, and the position of the inkjet printer 16 is adjusted horizontally by the left-right adjustment mechanism 18, so as to achieve the technical requirement of inkjetting at a suitable position of the product. The up-down adjustment mechanism 17 and the left-right adjustment mechanism 18 both adopt a handle rotation method, and the rotation of the handle drives the lead screw connected to the handle, thereby achieving precise adjustment of the position of the inkjet printer.

[0033] A material collection system is provided below the rotary mold 4. The material collection system in this embodiment includes a guide hopper 2, a conveyor belt 14 and a finished product hopper 15. The product 20 in the mold cavity that has completed inkjet printing continues to rotate with the rotary mold 4. When the rotary mold 4 rotates to the top of the guide hopper 2, the product 20 in the mold cavity falls into the guide hopper 2 due to gravity. The lower outlet of the guide hopper 2 corresponds to the conveyor belt 14. The conveyor belt 14 is connected to the pulley. The conveyor motor 13 drives the conveyor belt to circulate through the pulley to drive the product forward. The product in the guide hopper 2 falls from the outlet at the bottom of the guide hopper 2 to the conveyor belt 14 under the action of gravity, and is sent to the end of the conveyor belt 14 as the conveyor belt 14 moves. When the product reaches the end of the conveyor belt 14, the product continues to move away from the conveyor belt 14 due to inertia, and falls into the finished product hopper 15 under the action of gravity, thereby completing the material collection work.

[0034] Of course, the material collection system can also be simplified to the guide hopper 2 and the finished product hopper 15 arranged below the guide hopper 2, or even directly simplified to the finished product hopper 15 arranged below the rotary mold 4. When the product 20 in the mold cavity after inkjet printing continues to rotate to the top of the guide hopper 2 with the rotary mold 4, the product 20 in the mold cavity falls into the guide hopper 2 due to gravity, and then directly falls into the finished product hopper 15 through the outlet at the bottom of the guide hopper 2. Alternatively, the finished product hopper 15 is arranged below the rotary mold 4, and when the product 20 in the mold cavity after inkjet printing leaves the inkjet printer 16 with the rotary mold 4 and continues to rotate a certain angle, it directly falls into the finished product hopper 15 placed below the rotary mold 4 due to gravity, thereby realizing the recovery of finished products.

[0035] like Figure 3 As shown, the utility model provides an embodiment of a rotary mold structure. The rotary mold 4 is cylindrical in shape, with a cavity inside, a step at the bottom of the cavity, and a through hole on the step. The pressing plate 2 is pressed on the step and connected to the transmission shaft 5 by bolts passing through the through hole. The outer circumferential surface of the rotary mold 4 is evenly provided with mold cavities, and the mold cavities are arranged in a straight line along the axial direction of the mold, and each row of mold cavities is arranged in parallel along the circumferential direction. Each mold cavity is used to accommodate a product to be sprayed. The depth and size of the mold cavity are slightly larger than the size of the product to be processed, and the shape of the mold cavity is the same as the shape of the sprayed product. The mold cavity opening corresponds to the end of each channel of the guide plate 7. Due to the gravity and the pressure of the product behind, the product enters the mold cavity from the end of the channel of the guide plate 7 and is in a relatively stable state. After receiving the pulse signal, the rotary mold motor 11 rotates a certain angle to transfer the empty mold cavity at the rear position to the end of the channel of the guide plate 7, so as to realize the next round of product filling into the mold cavity. When the mold cavity containing the product rotates to the nozzle of the inkjet printer 16, the rotating mold 4 stops rotating, and the product 20 in the mold cavity is in a relatively static state, which is convenient for the inkjet printer 16 to print on the outer surface of the product.

[0036] The utility model orderly fills the products to be sprayed into the rotating mold cavity, utilizes the intermittent rotation of the rotating mold, rotates the rotating mold cavity containing the products to the corresponding position of the inkjet printer to achieve stable inkjet printing, and realizes the whole process of filling the products into the rotating mold cavity, spray printing, and leaving the mold cavity, and conveying and recycling through the continuous rotation of the mold. The product spraying process does not require manual participation, and the product spraying process is automated with the help of the control of the electronic control system, which greatly reduces the labor intensity of the operators and reduces the risk of contamination of the products by manual participation.

[0037] 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.
