Description

[Technical field]

[0001] The invention relates to the technical field of inkjet printers for fabrics, in particular to an inkjet digital printer. [Background technology]

[0002] Fabric inkjet digital printers are devices specially used for printing patterns on fabrics. This type of printer is mainly used for pattern printing on clothing fabrics, T-shirts, textile fabrics, etc. Some models also support thermal transfer function, which is suitable for scenes such as fabric printing and pattern design. In the process of digital inkjet printer printing on fabrics, it mainly transmits the fabrics through the transmission roller, so that the fabrics are transmitted to the nozzles fixedly connected to the base and arranged opposite to each other. At this time, the nozzles transmit ink to the fabrics, thereby realizing inkjet printing on the fabrics by the nozzles;

[0003] Although the above solution can print fabrics, there are still the following problems:

[0004] 1) When the transmission roller transmits the fabric, there will be a concave shape between the rollers of the transmission roller. Once the concave shape appears between the rollers, the part of the fabric between the rollers is likely to sag. When the fabric sags, if the nozzle fixedly connected to the base directly sprays ink on the fabric, it will cause a height difference between the concave surface and the flat surface of the fabric, resulting in uneven ink spraying on the fabric;

[0005] 2) Since the nozzle is in a fixed state, when the fabric is in the process of inkjet printing, when the position between the fabric and the nozzle is too high, it is easy to cause the ink to scatter when it is sprayed. Once the ink is scattered, the accuracy of the inkjet position will be reduced, and the position that does not need inkjet printing will also be contaminated with some scattered ink. [Summary of the invention]

[0006] The purpose of the present invention is to solve the problems in the prior art and to provide an inkjet digital printer capable of jetting ink on fabrics.

[0020] Beneficial effects of the present invention:

[0021] 1. The present invention arranges a sliding seat on the lifting seat, uses the sliding seat to drive the clamping plate to clamp the fabric, and uses the movement of the moving seat to drive the clamping plate to move, so that the clamping plate tightens the fabric. When the clamping plate tightens the fabric, the lifting seat is driven to rise and fall by the driving member, so that the fabric can be moved close to or away from the inkjet component, thereby reducing the uneven inkjet of the fabric caused by the height difference between the fabric and the inkjet component;

[0023] 3. The present invention arranges moving blocks on the lifting plate, and uses connecting rods 1 and 2 to connect the moving blocks, thereby reducing the situation where the driving member interferes with the normal movement of the moving seat due to the movement of the moving seat, and reducing the interference rate when the moving seat slides;

[0024] 4. The present invention drives the clamping plate to flip by a motor arranged on the sliding seat, and uses a fan to drive the airflow to enter the chamber through the pipeline, and the heating wire heats the airflow, and the heated airflow is discharged to the fabric through the air outlet to dry the fabric. By clamping and fixing the fabric and drying the fabric, the number of drying mechanisms on the base can be reduced, and the diameter size of the base can be greatly reduced because there is no need to set a drying mechanism, thereby greatly reducing the cost of manufacturing the base.

[0025] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.

[0038] like Figures 1 to 7 The present invention discloses an inkjet digital printer, comprising: a base 1, an inkjet component 2 arranged on the base 1, and a transmission roller 3 driven to rotate and connected to the base 1. It is worth mentioning that the transmission roller 3 is driven by a motor 38, the motor 38 is fixedly connected to the base 1, and the output shaft is fixedly connected to the transmission roller 3 to realize the rotation of the transmission roller 3, and the transmission rollers 3 are connected by belts. When the transmission roller 3 rotates, the transmission roller 3 drives the fabric to move below the built-in inkjet component 2. The inkjet component 2 is mainly composed of a lifting block 39 and a nozzle 41. The lifting block 39 is driven by a cylinder 40 to lift and connect to the base 1. The cylinder 40 is fixedly connected to the base 1, and the output shaft is fixedly connected to the lifting block 39 to realize the lifting of the lifting block 39, and the nozzle 41 is fixedly connected to the bottom surface of the lifting block 39. A conveying pipe is communicated with the nozzle 41, and the conveying pipe is mainly used to transmit ink into the nozzle 41, so that the nozzle 41 can transmit liquid to the fabric to color the fabric;

[0039] Since the base 1 is driven to synchronously slide and connect with the relatively arranged moving seat 4, the moving seat 4 is synchronously lifted and lowered with the lifting seat 5, the base 1 is provided with a driving member 6, which is respectively connected with the lifting seat 5, and the lifting seat 5 is driven to slide relatively and connect with the sliding seat 7, and the sliding seat 7 is driven to rotate and connect with the clamping plate 8, and the clamping plate 8 is located between the transmission rollers 3. The moving seat 4 is mainly driven by the two-way lead screw 2 42 and the four-motor 43. The two-way lead screw 2 42 is rotationally connected to the base 1 and is threadedly connected to the moving seat 4. The output shaft of the four-motor 43 fixedly connected to the base 1 is fixedly connected with the two-way lead screw 2 42, so that the four-motor 43 can drive the two-way lead screw 2 42 to drive the moving seat 4. The movable seat 4 moves relatively, so that the movable seat 4 indirectly drives the clamping plate 8 to adjust the position. After the adjustment of the position of the adjusting plate is completed, the movement of the sliding seat 7 drives the clamping plate 8 to move, so that the clamping plate 8 clamps the fabric. The sliding seat 7 is driven by the cylinder 2 44, and the cylinder 2 44 is fixedly connected to the lifting seat 5. The output shaft of the cylinder 2 44 is fixedly connected to the sliding seat 7, so that the relative movement of the sliding seat 7 can be achieved, so that the sliding seat 7 drives the clamping plate 8 to clamp the fabric. After the fabric is clamped, the movable seat 4 moves relatively again to make the clamping plate 8 tighten the fabric, thereby achieving the fixation of the fabric. After the fabric is fixed, the nozzle 41 transmits ink to spray ink on the fabric, thereby achieving the coloring of the fabric.

[0040] It is worth mentioning that the driving member 6 in the present invention includes: a lifting plate 9, a moving block 10, a connecting rod 1 11, a connecting rod 2 12, a limiting block 13 and a pushing rod 14:

[0041] Since the lifting plate 9 is driven to lift and connect to the base 1, the moving block 10 is relatively slidably connected to the lifting plate 9, the connecting rod 11 is fixedly connected to one of the moving blocks 10, and one end of the connecting rod 2 12 is fixedly connected to the other moving block 10, the limit block 13 is fixedly connected to the connecting rod 11, and the connecting rod 2 12 is provided with a limit groove 15 for the limit block 13 to slide, and the push rod 14 is fixedly connected to the moving block 10, and one end of the push rod 14 is fixedly connected to the lifting seat 5. The lifting plate 9 is moved by the cylinder The cylinder 45 is driven by the three 45, and the cylinder 45 is fixedly connected to the base 1, and the output shaft is fixedly connected to the lifting plate 9, so that the lifting and lowering of the lifting plate 9 can be realized, and the connecting rod 11 and the connecting rod 2 12 can avoid the moving block 10 from interfering with the normal lifting and lowering of the lifting plate 9 when it moves through a telescopic manner. When the lifting plate 9 is lifted or lowered, the pushing rod 14 will drive the lifting seat 5 to lift and lower, thereby realizing that the lifting seat 5 drives the clamping plate 8 to adjust the position, and the limit block 13 and the limit groove 15 can prevent the connecting rod 11 and the connecting rod 2 12 from rotating.

[0042] Specifically, a chamber 16 is provided on the clamping plate 8, and an air outlet 17 communicated with the chamber 16 is provided on the clamping plate 8. A motor 18 is fixedly connected to the sliding seat 7, and the output shaft of the motor 18 is fixedly connected to the clamping plate 8. A fan 19 is fixedly connected to the base 1, and the fan 19 is communicated with the chamber 16 through a pipeline. A heating wire 20 is fixedly connected in the chamber 16. Therefore, when the inkjet of the fabric is completed, the motor 18 is started, and the clamping plate 8 is turned over by the output shaft of the motor 18, and the fan 19 is started. The fan 19 is used to transmit the airflow through the pipeline into the chamber 16, and the heating wire 20 heats the airflow and dries the ink on the fabric through the air outlet 17. The fabric can be clamped and dried at the same time. The two are used for dual purposes, which reduces the number of components with multiple drying mechanisms and reduces the overall length of the printer.

[0043] Specifically, a connecting seat 21 is connected to the base 1 for lifting and lowering, a rotating disk 22 is driven to rotate on the connecting seat 21, and a winding roller 23 is detachably connected to the rotating disk 22. The connecting seat 21 is driven by a cylinder 46, and the cylinder 46 is fixedly connected to the base 1, and the output shaft is fixedly connected to the connecting seat 21, so that the lifting and lowering of the connecting seat 21 can be realized, and the rotating disk 22 is driven by a motor 5 47, and the motor 5 47 is fixedly connected to the connecting seat 21, and the output shaft is fixedly connected to the rotating disk 22, so that the rotation of the rotating disk 22 can be realized. When the rotating disk 22 rotates, the rotating disk 22 can drive the winding roller 23 to rotate, thereby realizing the winding of the fabric by the winding roller 23, which is convenient for people to collect the fabric.

[0044] Specifically, a concave limit block 24 is driven to slide on the rotating disk 22, and a limit groove 25 is opened on the winding roller 23 for the limit block to enter, thereby fixing the winding roller 23. The concave limit block 24 is driven by the cylinder 5 48, and the cylinder 5 48 is fixedly connected to the rotating disk 22, and one end is fixedly connected to the concave limit block 24, so that the concave limit block 24 can be moved, thereby fixing the winding roller 23.

[0045] Specifically, a limit plate 26 is fixedly connected to the concave limit block 24, and a connecting block 27 is elastically slidably connected to the limit plate 26, so that the connecting block 27 can position the fabric, thereby preventing the fabric from being offset during the winding process. It is worth mentioning that the connecting block 27 is elastically slidably connected via a spring 49, and the spring 49 is fixedly connected to the limit plate 26, and one end is fixedly connected to the connecting block 27, so that the connecting block 27 can limit the fabric.

[0046] Specifically, since the base 1 is connected to a support seat 28 for lifting and lowering, a displacement seat 29 is driven to slide relatively on the support seat 28, and a push seat 30 is driven to rotate on the displacement seat 29, the push seat 30 is located below the winding roller 23, and the push seat 30 is mainly used to support the winding roller 23 to facilitate the unloading of the winding roller 23, and the support seat 28 is driven by a cylinder 650, and the cylinder 650 is fixedly connected to the base 1, and the output shaft is fixedly connected to the support seat 28, so that the lifting and lowering of the support seat 28 can be realized, so that the support seat 28 is close to the winding roller 23. After the winding of the winding roller 23 is completed, the limit block releases the winding roller 23, and the winding roller 23 will fall onto the push seat 30, thereby realizing the unloading of the winding roller 23 by the push seat 30.

[0047] Specifically, since the support seat 28 is driven to rotate with a bidirectional lead screw 31, the bidirectional lead screw 31 is threadedly connected to the displacement seat 29, and the support seat 28 is rotatably connected with a rotating block 32, one end of the rotating block 32 is fixedly connected to the bidirectional lead screw 31, the rotation of the rotating block 32 can drive the bidirectional lead screw to drive the displacement seat 29 to move, thereby realizing the adjustment of the position of the displacement seat 29, so that the displacement seat 29 is adjusted to a length that matches the support of the winding roller 23.

[0048] Specifically, a second motor 33 is fixedly connected to the displacement seat 29, and is fixedly connected to the pushing seat 30 through the output shaft of the second motor 33, and a positioning block 34 is elastically slidably connected to the pushing seat 30. A positioning groove 35 for the positioning block 34 to enter is provided on the winding roller 23, and the positioning block 34 can position the second limit groove 25 on the winding roller 23, thereby increasing the positioning effect between the limit groove and the concave limit block 24, and the second motor 33 can drive the pushing seat 30 to rotate, and can enable the pushing seat 30 to drive the winding roller 23 to discharge the wound material during the rotation process. It is worth mentioning that the positioning block 34 is elastically slidably connected through a second spring 51, and the second spring is fixedly connected to the pushing seat and one end of the spring is fixedly connected to the positioning block, so that the positioning block can be reset.

[0049] Specifically, since the base 1 is located below the support seat 28 and is obliquely fixedly connected with a guide plate 36 , the guide plate 36 can guide the winding roller 23 so that it can be guided to the ground.

[0050] Specifically, a buffer sponge 37 is fixedly connected to the guide plate 36 , and the buffer sponge 37 is mainly used to buffer the winding roller 23 .

[0051] The principle of the present invention is as follows: the lifting seat 5 is driven to move by the driving member 6, so that the lifting seat 5 indirectly drives the clamping plate 8 to move up and down, so that the position of the clamping plate 8 is adjusted. Once the position adjustment of the clamping plate 8 is completed, the sliding seat 7 moves, and the relative movement of the sliding seat 7 is utilized to drive the clamping plate 8 to clamp the fabric. After the fabric is clamped, the moving seat 4 moves relatively to tighten the fabric. After the fabric is tightened, the inkjet member 2 is utilized to spray ink on the fabric, thereby realizing the processing of the fabric.

[0052] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention belongs to the protection scope of the present invention.
