[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] The following is for reference. Figures 1 to 5 The printing module of this application is described in detail.

[0033] refer to Figures 1 to 3According to an embodiment of the present invention, the inkjet printing module includes a mounting frame 100, a movable frame 200, and an inkjet printing assembly 300. The mounting frame 100 has two slide rails 110 arranged side by side, and each slide rail 110 is provided with a slider 120 that can slide on it. The movable frame 200 is disposed between the two slide rails 110 and has a first connecting member 210 and two second connecting members 220. The two second connecting members 220 are respectively connected to the two sliders 120. The first connecting member 210 is located between the two second connecting members 220 and is located on the horizontal lower side of the second connecting members 220. The inkjet printing assembly 300 is disposed between the two slide rails 110 and is connected to the first connecting member 210.

[0034] For example, such as Figures 1 to 3 As shown, the printing module includes a mounting frame 100, a movable frame 200, and a printing assembly 300. The mounting frame 100 has two slide rails 110 arranged side by side in the left-right direction. Both slide rails 110 extend in the front-back direction, and each slide rail 110 has a slider 120 that can slide in the front-back direction. The movable frame 200 is located between the two slide rails 110. The movable frame 200 includes a first connecting member 210 and two second connecting members 220. The two second connecting members 220 are distributed in the left-right direction and are fixedly connected to the sliders 120 on the two slide rails 110 respectively. The first connecting member 210 is located between the two second connecting members 220 and is located on the horizontal lower side of the second connecting members 220. The printing assembly 300 is located between the two slide rails 110 and is connected to the first connecting member 210. The printing assembly 300 is used to print on materials.

[0035] Furthermore, under the action of external force, the printing component 300 can move back and forth along the slide rail 110.

[0036] Understandably, since the printing assembly 300 is connected to the first connector 210, and the first connector 210 is located horizontally below the second connector 220, the height of the printing assembly 300 can be lower after installation. Consequently, the center of gravity of the printing assembly 300 is lower, and the printing assembly 300 can move more smoothly and accurately as it slides along the slide rail 110. At the same time, the lower height of the printing assembly 300 allows the vertical dimensions of the entire printing module to be smaller, resulting in a smaller and more compact overall structure.

[0037] It is understandable that, since the printing assembly 300 is provided with two slide rails 110 and the two second connectors 220 are respectively connected to the sliders 120 on the two slide rails 110, the force between the printing assembly 300 and the mounting bracket 100 is more uniform, and the printing assembly 300 can be more stable when sliding along the slide rails 110.

[0038] In some embodiments of the present utility model, there are two movable frames 200, and the two movable frames 200 are respectively connected to the opposite ends of the printing component 300.

[0039] For example, there are two movable frames 200, and the two movable frames 200 are respectively connected to the front and rear ends of the printing component 300.

[0040] It can be understood that by providing two movable frames 200, the two movable frames 200 can respectively support the front and rear ends of the printing component 300. Thus, under the action of an external force, the two movable frames 200 can slide back and forth synchronously following the slider 120 on the slide rail 110 to drive the printing component 300 to slide back and forth along the slide rail 110; the provision of the two movable frames 200 enables the self-gravity load of the printing component 300 to be evenly distributed to the mounting frame 100 through the two movable frames 200, and the printing component 300 can slide more smoothly along the slide rail 110.

[0041] In some embodiments of the present utility model, the movable frame 200 further includes two third connecting members 230, and the opposite ends of the first connecting member 210 are respectively detachably connected to the two second connecting members 220 through the two third connecting members 230.

[0042] For example, as [[ID=IS=15]] Figure 3 shown, the movable frame 200 further includes two third connecting members 230. The two third connecting members 230 are distributed in the left-right direction. The upper and lower ends of the third connecting member 230 on the left are respectively detachably connected to the left end of the first connecting member 210 and the second connecting member 220 on the left. The upper and lower ends of the third connecting member 230 on the right are respectively detachably connected to the right end of the first connecting member 210 and the second connecting member 220 on the right, so that the entire movable frame 200 forms an inverted "U" shape, and the second connecting member 220 is fixedly connected to the upper end of the slider 120.

[0043] It can be understood that by setting the entire movable frame 200 into an inverted "U" shape and connecting the printing component 300 to the first connecting member 210 at the bottom side, the center of gravity of the entire printing component 300 is lower. Moreover, the inverted "U" shape design of the movable frame 200 enables the gravity load of the printing component 300 to be more evenly distributed to the two slide rails 110 through the movable frame 200, so that the printing component 300 can slide more smoothly along the slide rail 110 under the action of an external force. <IS=

[0044] It is understandable that the movable frame 200 is generally shaped like an inverted "V". The shape of the movable frame 200 is relatively complex, making it difficult to manufacture using a one-piece molding process. By making the first connector 210 and the third connector 230 detachably connected, and the second connector 220 and the third connector 230 also detachably connected, the first connector 210, the second connector 220, and the third connector 230 can be manufactured individually using a one-piece molding process, and then assembled together. This simplifies the manufacturing process and reduces the manufacturing cost of the movable frame 200 of the printing module in this application.

[0045] In some embodiments of this utility model, the movable frame 200 further includes two fourth connecting members 240, both of which are detachably connected to the first connecting member 210. The connected second connecting member 220 and third connecting member 230 are also detachably connected to the same fourth connecting member 240.

[0046] For example, such as Figure 3 As shown, the movable frame 200 also includes two fourth connectors 240, which are distributed in the left-right direction. The fourth connector 240 on the left is detachably connected to the left end of the first connector 210, the second connector 220 on the left, and the third connector 230 on the left, respectively. The fourth connector 240 on the right is detachably connected to the right end of the first connector 210, the second connector 220 on the right, and the third connector 230 on the right, respectively.

[0047] It is understandable that by setting the fourth connector 240, the first connector 210, the second connector 220 and the third connector 230 connected in sequence can be reinforced by the fourth connector 240, thereby enhancing the overall structure of the movable frame 200.

[0048] In some embodiments of this utility model, reference is made to Figure 4 The printing assembly 300 includes a lifting structure 310 and a printer 320. The lifting structure 310 is mounted on the first connector 210 and connected to the printer 320. The lifting structure 310 is used to drive the printer 320 to perform lifting movements. The printer 320 is used to print materials.

[0049] Understandably, driven by the lifting structure 310, the inkjet printer 320 can perform lifting movements, enabling it to print materials of different thicknesses. Furthermore, the operator can adjust the height of the inkjet printer 320 according to actual needs through the lifting structure 310, thereby improving the adaptability of the inkjet printing module of this application.

[0050] In some embodiments of this utility model, reference is made to Figure 4 The lifting structure 310 includes a first driver 311 and a connecting frame 312. The inkjet printer 320 is slidably connected to the connecting frame 312 in the vertical direction. The connecting frame 312 is connected to the first connecting member 210. The first driver 311 is mounted on the inkjet printer 320. The output end of the first driver 311 is connected to the connecting frame 312. Under the drive of the first driver 311, the inkjet printer 320 can move up and down relative to the connecting frame 312.

[0051] It is understandable that the inkjet printer 320 often integrates electronic components such as controllers and power supplies. The first driver 311 needs to be connected to the controllers and power supplies via wires. By placing the first driver 311 on the inkjet printer 320, the first driver 311 can move up and down with the inkjet printer 320, thereby reducing the probability of wire tangling problems.

[0052] In a further embodiment of this utility model, reference is made to... Figure 5 The first driver 311 includes a first motor 311a, a reducer 311b, a lead screw 311c, and a sliding sleeve 311d. The first motor 311a and the reducer 311b are both mounted on the inkjet printer 320. The lead screw 311c extends vertically and is rotatably mounted on the inkjet printer 320. The first motor 311a is connected to the lead screw 311c via the reducer 311b. The sliding sleeve 311d is threadedly connected to the lead screw 311c and fixedly connected to the connecting frame 312. Driven by the first motor 311a, the first motor 311a can drive the lead screw 311c to rotate via the reducer 311b, so that the reducer 311b drives the inkjet printer 320 to perform lifting and lowering movements.

[0053] Understandably, driven by the first motor 311a, the reducer 311b can drive the lead screw 311c to rotate. Since the lead screw 311c is threadedly connected to the sliding sleeve 311d, during the rotation of the lead screw 311c, the lead screw 311c and the sliding sleeve 311d will have relative motion in the vertical direction. Since the sliding sleeve 311d is fixedly connected to the connecting frame 312, the sliding sleeve 311d cannot move in the vertical direction, so the lead screw 311c can move in the vertical direction. The lead screw 311c drives the reducer 311b and the inkjet printer 320 to move in the vertical direction.

[0054] Understandably, the design of the lead screw 311c and the sliding sleeve 311d makes the motor's vertical displacement drive of the inkjet printer 320 more precise.

[0055] Understandably, the reducer 311b allows the lead screw 311c to rotate at a lower speed, so that, given a fixed output power of the first motor 311a, the lead screw 311c can generate a greater torque, thus enabling the lead screw 311c to have a greater driving force to drive the inkjet printer 320 to perform lifting and lowering movements.

[0056] In some embodiments of this utility model, reference is made to Figure 5 The lead screw 311c is located between the inkjet printer 320 and the connecting frame 312.

[0057] It should be noted that if there are many impurities adhering to the lead screw 311c, these impurities will get stuck between the lead screw 311c and the sliding sleeve 311d, thus affecting the normal rotation of the lead screw 311c.

[0058] It is understandable that by placing the lead screw 311c between the inkjet printer 320 and the connecting frame 312, the inkjet printer 320 and the connecting frame 312 can cooperate to protect the lead screw 311c, thereby reducing the probability of impurities adhering to the lead screw 311c and extending the service life of the lead screw 311c.

[0059] In some embodiments of this utility model, reference is made to Figure 4 and Figure 5 The printing assembly 300 also includes two guide structures 330. Each guide structure 330 includes a connecting block 331 and a guide rail 332. The guide rail 332 extends vertically, and the connecting block 331 is slidably mounted on the guide rail 332. In the same guide structure 330, the connecting block 331 and the guide rail 332 are respectively connected to the connecting frame 312 and the printing machine 320. The lead screw 311c is located between the two guide structures 330.

[0060] Understandably, by placing the lead screw 311c between the two guide structures 330, the two guide structures 330 can work with the screen printing machine and the mounting bracket 100 to better protect the lead screw 311c, thereby further extending the service life of the lead screw 311c.

[0061] It is understandable that by setting two guide structures 330 and placing the lead screw 311c between the two guide structures 330, the inkjet printer 320 can move more stably in the vertical direction under the drive of the lead screw 311c, thereby improving the stability of the inkjet printer 320 in the vertical direction.

[0062] In some embodiments of this utility model, the mounting bracket 100 is further provided with a second driver 130. The second driver 130 includes a second motor 131, a transmission belt 132 and a clamping member 133. The second motor 131 is driven to drive the transmission belt 132. The clamping member 133 is mounted on the transmission belt 132 and fixedly connected to the slider 120. Under the drive of the second motor 131, the transmission belt 132 can drive the slider 120 to slide along the slide rail 110 through the clamping member 133.

[0063] For example, such as Figure 2 As shown, the second driver 130 includes a second motor 131, a transmission belt 132, and a clamping member 133. The transmission belt 132 extends in the front-back direction. The clamping member 133 is fixedly connected to the transmission belt 132 and to the slider 120. Under the drive of the second motor 131, the transmission belt 132 can drive the clamping member 133 to move in the front-back direction, so that the clamping member 133 can drive the slider 120 to slide in the front-back direction along the slide rail 110, thereby enabling the slide rail 110 to drive the printing assembly 300 to slide in the front-back direction, so as to realize the position adjustment of the printing assembly 300 in the front-back direction.

[0064] Understandably, the second motor 131 is configured to allow the second motor 131 to accurately adjust the position of the printing assembly 300 in the front-to-back direction via the transmission belt 132, so that the printing assembly 300 can print over a larger area.

[0065] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
