Description

Technical Field

[0001] The utility model is applicable to the technical field of inkjet printers, and particularly relates to an adjustable positioning auxiliary device for an inkjet printer. Background Technique

[0002] At present, an inkjet printer is a device that uses software control to identify products in a non-contact manner.

[0003] However, when using an inkjet printer to spray and mark the surfaces of multiple groups of objects that are continuously moving on the surface of a conveyor belt, in order to improve the efficiency of inkjet coding, the position at the inkjet gun head will be adjusted before use, and after the adjustment is completed, it will no longer be changed to ensure that the same position on the object surface can be inkjet processed. When the object moves under the inkjet gun along with the operation of the conveyor belt, it is very easy for the object to shift laterally due to its own light weight when moving along with the conveyor belt, resulting in a change in the inkjet position and affecting the inkjet quality. Therefore, we propose an adjustable positioning auxiliary device for an inkjet printer. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide an adjustable positioning auxiliary device for an inkjet printer, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An adjustable positioning auxiliary device for an inkjet printer includes a mounting base, a conveyor belt is installed inside the mounting base, a regulating bracket is fixedly installed on the middle surface of the outer side of the top of the mounting base, an inkjet gun is arranged on the top of the regulating bracket, fixing frames are fixedly installed on the surfaces of both sides of the top of the mounting base, a hollow frame is fixedly installed on the inner top surface of each fixing frame, and a transmission frame is fixedly installed between the outer sides of the two fixing frames;

[0007] A bidirectional lead screw is rotatably installed in the middle of each hollow frame through a bearing, transmission sleeves are movably sleeved on the surfaces of both ends of the outer side of each bidirectional lead screw through threads, a transmission rod is fixedly installed on the outer surface of each transmission sleeve, and the transmission rod penetrates and is slidably inserted into the bottom of the hollow frame. A transmission frame is fixedly installed on the end surface of each transmission rod away from the transmission sleeve, and a connecting plate is fixedly installed on the bottom surface of each transmission frame, and the connecting plate is located above the outer side of the conveyor belt;

[0008] Rotating rods are rotatably installed on both sides inside the transmission frame through bearings, and the side of the rotating rod is fixedly connected to the top surface of the outer side of the bidirectional lead screw. Transmission sprockets are fixedly sleeved on the middle surfaces of each rotating rod, and a transmission chain ring is meshed and sleeved between the outer sides of the two transmission sprockets.

[0009] By adopting the above technical solution, under the meshing drive of the drive sprocket and the drive chain ring, and under the rotational drive of the bidirectional lead screw on the drive sleeve, the two sets of connecting plates can move horizontally synchronously towards or away from each other, adjusting the distance between the two sets of connecting plates, ensuring that the connecting plates and the guide rollers arranged on their sides can perform a pressing and limiting process on the outer side of the object to be spray-coded located on the conveyor belt surface, and preventing the object from shaking randomly during spray-coding and affecting the spray-coding quality.

[0010] As an alternative solution of the technical solution of the present application, a servo motor is fixedly installed on the outer surface of the drive frame, and the side of the transmission shaft of the servo motor is fixedly connected to the outer side of the rotating rod through a coupling.

[0011] By adopting the above technical solution, the structure of the servo motor can provide the power required for the rotation of the rotating rod.

[0012] As an alternative solution of the technical solution of the present application, fixing plates are fixedly installed on the surfaces at both ends of the side of each connecting plate, and the number of fixing plates is several groups. An I-shaped rod is vertically rotatably installed between the inner sides of every two groups of fixing plates through bearings. Guide rollers are fixedly sleeved on the middle surfaces of each I-shaped rod, and the guide rollers are rotatably arranged above the outer side of the conveyor belt.

[0013] By adopting the above technical solution, through the rotation of the guide rollers, while ensuring that the guide rollers can perform a limiting and anti-offset process on the object to be spray-coded, it also ensures that the object after spray-coding can move horizontally along with the operation of the conveyor belt.

[0014] As an alternative solution of the technical solution of the present application, both the drive sprocket and the drive chain ring are rotatably arranged inside the drive frame, and the outer side of the drive sprocket meshes with the inner side of the drive chain ring.

[0015] By adopting the above technical solution, under the meshing drive of the drive sprocket and the drive chain ring, the transmission synchronization rationality of the entire device is ensured.

[0016] Compared with the prior art, the present utility model has the following beneficial effects:

[0017] 1. An adjustable positioning auxiliary device for the inkjet printer of the technical solution of the present application, under the meshing drive of the transmission chain ring and the transmission sprocket, can drive the rotating rods on both sides inside the transmission frame to rotate synchronously and in the same direction under the drive of the servo motor, and then drive the bidirectional lead screws inside the two hollow frames to rotate synchronously and in the same direction. Combining the rotational drive of the bidirectional lead screw on the transmission sleeve and the connection drive of the transmission rod and the transmission frame, it can provide the connecting plate above the outer side of the conveyor belt to move horizontally synchronously towards or away from each other, adjust the distance between the two connecting plates, and ensure that the connecting plate and the guiding rollers arranged on its side can perform abutting and limiting treatment on the outer side of the object to be inkjet printed on the surface of the conveyor belt, avoiding any shaking of the object during inkjet printing and affecting the inkjet printing quality.

[0018] 2. An adjustable positioning auxiliary device for the inkjet printer of the technical solution of the present application, rotatably arranges the guiding rollers on the side of the connecting plate through the fixing plate and the I-shaped rod. After the guiding rollers move with the adjustment and movement of the connecting plate, the guiding rollers can fit against the outer wall of the object to be inkjet printed to perform abutting and limiting on it. At the same time, combined with the rotation of the guiding rollers, it can ensure that the object can still move out from the bottom of the inkjet printing gun with the movement of the conveyor belt after the inkjet printing is completed, thereby ensuring the rationality of the movement of the object during inkjet printing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] As Figures 1-3As shown in the figure, the present utility model provides a technical solution: an adjustable positioning auxiliary device for a coding machine. A servo motor 31 is fixedly installed on the outer surface of a transmission frame 22, and the side of the transmission shaft of the servo motor 31 is fixedly connected to the outer side of a rotating rod 29 through a coupling.

[0024] In this technical solution (as shown by Figure 1 , Figure 2 and Figure 3 ), on both side surfaces of the top of an installation base 1, fixed frames 2 are fixedly installed. On the inner top surface of each fixed frame 2, a hollow frame 21 is fixedly installed. Between the outer sides of the two groups of fixed frames 2, a transmission frame 22 is fixedly installed. On both sides inside the transmission frame 22, rotating rods 29 are rotatably installed through bearings, and the side of the rotating rod 29 is fixedly connected to the outer top surface of a bidirectional lead screw 25. On the middle surface of each rotating rod 29, a transmission sprocket 23 is fixedly sleeved. Between the outer sides of the two groups of transmission sprockets 23, a transmission chain ring 24 is meshingly sleeved. The transmission sprocket 23 and the transmission chain ring 24 are both rotatably arranged inside the transmission frame 22, and the outer side of the transmission sprocket 23 is meshed with the inner side of the transmission chain ring 24.

[0025] In this technical solution (as shown by Figure 1 , Figure 2 and Figure 3 ), in the middle of the inner side of each hollow frame 21, a bidirectional lead screw 25 is rotatably installed through a bearing. On both ends of the outer surface of each bidirectional lead screw 25, a transmission sleeve 26 is movably sleeved through threads. On the outer surface of each transmission sleeve 26, a transmission rod 27 is fixedly installed, and the transmission rod 27 penetrates and is slidably inserted into the bottom of the hollow frame 21. On the end surface of each transmission rod 27 away from the transmission sleeve 26, a transmission bracket 28 is fixedly installed. On the bottom surface of each transmission bracket 28, a connecting plate 3 is fixedly installed, and the connecting plate 3 is located above the outer side of a conveyor belt 11.

[0026] In this technical solution (as shown by Figure 1 , Figure 2 and Figure 3 ), on both ends of the side surface of each connecting plate 3, fixing plates 4 are fixedly installed, and the number of the fixing plates 4 is several groups. Between the inner sides of every two groups of fixing plates 4, an I-shaped rod 41 is vertically rotatably installed through a bearing. On the middle surface of each I-shaped rod 41, a guiding roller 42 is fixedly sleeved, and the guiding roller 42 is rotatably arranged above the outer side of the conveyor belt 11.

[0027] In some technical solutions (as shown by Figure 1 , Figure 2 and Figure 3 ), a conveyor belt 11 is installed inside the installation base 1. On the middle surface of the outer side of the top of the installation base 1, an adjusting bracket 12 is fixedly installed, and a coding gun 13 is arranged on the top of the adjusting bracket 12.

[0028] During operation, the objects to be inkjet-printed are sequentially placed on the left surface of the conveyor belt 11. Then, the servo motor 31 is started to operate, driving the rotating rod 29 and the transmission sprocket 23 sleeved on its surface. Under the meshing drive of the transmission chain ring 24 and the transmission sprocket 23, the two groups of rotating rods 29 can be driven to rotate synchronously and in the same direction. Subsequently, under the connection drive of the rotating rod 29, the two groups of bidirectional lead screws 25 can be driven to rotate synchronously and in the same direction. Under the rotational drive of the bidirectional lead screw 25 on the transmission sleeve 26, the two groups of transmission sleeves 26 can be driven to move horizontally synchronously and towards each other. Furthermore, under the connection drive of the transmission rod 27 and the transmission frame 28, the two groups of connecting plates 3 can be driven to move horizontally and towards each other on the surface of the conveyor belt 11 synchronously. Until the outer wall of the guiding roller 42 on the outside of the connecting plate 3 fits against the outer surface of the object to be inkjet-printed, it is subjected to a pressing and limiting process to prevent it from shifting during movement. Synchronously, the inkjet position of the inkjet gun 13 is adjusted in combination with the adjusting bracket 12. Then, the conveyor belt 11 is started to operate. Under the rotation of the guiding roller 42, the positioned objects are driven to pass under the inkjet gun 13 in sequence. The surface of the object is subjected to inkjet printing processing by the structural action of the inkjet gun 13.
