Description
Technical Field
[0001] This utility model relates to the field of printing equipment, and specifically to an adjustable bidirectional printing device. Background Technology
[0002] As a step in fabric beautification, the printing process requires creating richly colored and clearly defined patterns on the fabric surface according to design requirements. Existing printing equipment has been found to have the following shortcomings in practical use: The printing direction is unidirectional; most devices can only achieve unidirectional printing along the fabric length. If additional printing is needed along the fabric width, secondary feeding and adjustment of the fabric transport direction are required, increasing the complexity of the process. Furthermore, the required position of the printed pattern on the fabric varies, but the spacing and height of the printing components in existing equipment are mostly fixed, or require adjustment through multiple independent drive mechanisms. This adjustment process is cumbersome and makes it difficult to ensure synchronous linkage between the printing components and the support structure.
[0003] Therefore, in order to overcome the shortcomings of the existing technology, it is necessary to design an adjustable bidirectional printing device with a simple structure. Utility Model Content
[0004] This invention provides an adjustable bidirectional printing device to address the problems of existing technologies.
[0005] The objective of this utility model can be achieved through the following technical solution: An adjustable bidirectional printing device includes: a frame, a feeding assembly, a transmission guide roller group, a horizontal printing assembly, and a vertical printing assembly, wherein the transmission guide roller group sequentially transfers the fabric from the feeding assembly, the horizontal printing assembly, and the vertical printing assembly; the horizontal printing assembly includes an upper power assembly, a horizontal printing wheel, a lower power assembly, and support columns; the upper power assembly drives two sets of horizontal printing wheels to move synchronously inward or outward; the lower power assembly drives two sets of support columns to move synchronously inward or outward; the support columns are located directly below the horizontal printing wheel; the vertical printing assembly includes an upper power assembly, a vertical printing wheel, and a base plate; the upper power assembly drives the vertical printing wheel to reciprocate above the base plate.
[0006] Further improvements include an upper power assembly comprising a motor, a timing belt, a timing pulley, a screw, a timing belt, and a guide rail; a lower power assembly comprising a screw, a slider, a nut, and a guide rail; the output end of the motor is connected to the timing pulley, which transmits power via the timing belt; the timing belt is connected to a timing pulley fixed on the screw to drive the screw to rotate; another set of timing pulleys fixed on the screw is connected to a timing pulley on the screw via the timing belt; the left and right ends of the screw and the screw are connected to the timing pulley on the screw. The threads on the left and right ends are reversed; two sets of transverse printing wheels are respectively connected to the left and right ends of the screw through slider one, nut one, and screw one. Nut one is threaded to screw one, slider one is fixedly connected to nut one, and the transverse printing wheel is mounted on slider one.

Nut two is threaded to screw two, slider two is fixedly connected to nut two, support column is mounted on slider two, and slider two is slidably mounted on guide rail two.
[0007] In a further improvement, the upper power assembly two includes a top plate, a guide rail three, a rack, a gear, a motor two, a synchronous pulley five, a synchronous belt three, a synchronous pulley six, and a slider three.

The third motor and the synchronous pulley set drive the drive shaft to rotate.
[0010] Compared with the prior art, the advantages of this adjustable bidirectional printing device are as follows: By integrating horizontal and vertical printing components, the fabric can be printed in both length and width directions in a single transfer, eliminating the need for secondary feeding and adjustment.

[0013] The following describes the embodiments and appendices. Figures 1-5 The technical solution of this utility model will be further described below.
[0014] Example 1 An adjustable bidirectional printing device includes: a frame 1, a feeding assembly 2 mounted on the frame 1, a transfer guide roller group 3, a horizontal printing assembly 4, and a vertical printing assembly 5. The transfer guide roller group 3 sequentially transfers fabric from the feeding assembly 2, the horizontal printing assembly 4, and the vertical printing assembly 5. The horizontal printing assembly 4 includes an upper power assembly 41, a horizontal printing wheel 42, a lower power assembly 43, and a support column 44. The upper power assembly 41 drives two sets of horizontal printing wheels 42 to move synchronously inward or outward, and the lower power assembly 43 drives two sets of support columns 44 to move synchronously inward or outward. The support column 44 is located directly below the horizontal printing wheel 42. The vertical printing assembly 5 includes an upper power assembly 51, a vertical printing wheel 52, and a base plate 53. The upper power assembly 51 drives the vertical printing wheel 52 to reciprocate above the base plate 53.
[0015] like Figures 1-5 As shown, the working principle of this utility model is as follows: The feeding assembly is responsible for the stable release of the rolled fabric. The conveying guide roller group forms a continuous and stable fabric conveying path through the coordinated rotation of multiple sets of guide rollers, conveying the fabric sequentially to the horizontal printing assembly and the vertical printing assembly. In the horizontal printing assembly, the upper power assembly and the lower power assembly drive the horizontal printing wheel and the support column respectively, and the two maintain coordinated movement. The support column forms stable support directly below the horizontal printing wheel to ensure uniform printing pressure. The rolling direction of the horizontal printing wheel is consistent with the fabric movement direction, realizing printing processing along the length of the fabric. After horizontal printing, the fabric continues to be conveyed to the vertical printing assembly. The upper power assembly drives the vertical printing wheel to reciprocate above the fixed base plate. Its movement direction is perpendicular to the fabric conveying direction, thereby completing the printing processing along the width of the fabric, ultimately realizing bidirectional printing of the fabric.
[0016] By integrating horizontal and vertical printing components, the fabric can be printed in both length and width directions in a single transfer, eliminating the need for secondary feeding and adjustment. This effectively shortens the processing cycle and solves the problem of low efficiency in unidirectional printing of traditional devices. The upper and lower power components can drive the horizontal printing wheel and support column to move synchronously inward or outward. This allows for flexible adjustment of the printing area according to the fabric width and the position of the printing pattern, adapting to the processing needs of fabrics of different specifications. This solves the problems of cumbersome adjustment and poor adaptability of traditional devices.
[0017] As a further preferred embodiment, the upper power assembly 41 includes a motor 411, a timing belt 412, a timing pulley 413, a screw 414, a timing belt 415, and a guide rail 417; the lower power assembly 43 includes a screw 431, a slider 441, a nut 432, and a guide rail 432; the output end of the motor 411 is connected to the timing pulley 413, the timing pulley 413 transmits power through the timing belt 412, and the timing belt 412 is connected to the timing pulley 433 fixed on the screw 431 to drive the screw 431 to rotate; another set of timing pulleys 434 fixed on the screw 431 is connected to the timing pulleys 416 on the screw 414 through the timing belt 415; the screw 414 is left The threads at the left and right ends of the first and second ends of the screw 414 are reversed. Two sets of transverse printing wheels 42 are respectively connected to the left and right ends of the screw 414 via slider 421 and nut 422. Nut 422 is threadedly connected to screw 414, and slider 421 is fixedly connected to nut 422. The transverse printing wheels 42 are mounted on slider 421, which is slidably mounted on guide rail 417. Two sets of support columns 44 are respectively connected to the screw 431 via slider 441 and nut 431. Nut 431 is threadedly connected to screw 431, and slider 441 is fixedly connected to nut 431. Support columns 44 are mounted on slider 441, which is slidably mounted on guide rail 432.
[0018] After the motor starts, its output end drives synchronous pulley one to rotate. Synchronous pulley one transmits power to synchronous pulley two on screw two via synchronous belt one, driving screw two to rotate. At the same time as screw two rotates, synchronous pulley three fixed on its surface drives synchronous pulley four on screw one to rotate via synchronous belt two, thus achieving synchronous rotation of screw one and screw two. Since both screw one and screw two adopt a reverse thread design at their left and right ends, when screw one rotates, the nuts one at its left and right ends will move in opposite directions, and the slider one fixedly connected to the nuts one will slide synchronously in opposite directions along guide rail one, thereby driving the two sets of transverse printing wheels to move inward or outward synchronously. Similarly, when screw two rotates, the nuts two at its left and right ends drive the slider two to slide synchronously in opposite directions along guide rail two, achieving synchronous inward or outward movement of the two sets of support columns.
[0019] As a further preferred embodiment, the upper power assembly 51 includes a top plate 511, a guide rail 512, a rack 513, a gear 514, a motor 515, a synchronous pulley 516, a synchronous belt 517, a synchronous pulley 518, and a slider 519. The top plate 511 is mounted on the frame 1, the rack 513 is fixed to the upper end of the top plate 511, the gear 514 is mounted on the rack 513, the guide rail 512 is fixed to the lower end of the top plate 511, and the slider 519... The slider is slidably mounted on guide rail 3 512. Motor 2 515 is located at the lower end of slider 3 519. Synchronous wheel 6 518 and gear 514 are symmetrically arranged on both sides of the upper end of slider 3 519. The output end of motor 2 515 is connected to synchronous wheel 516. Synchronous wheel 6 518 is connected to gear 514 through a transmission shaft. Synchronous wheel 516 and synchronous wheel 6 518 are connected to synchronous belt 3 517. Vertical printing wheel 52 is located at the lower end of slider 3 519.
[0020] Motor 2 is fixed to the lower end of slider 3. After starting, its output end drives synchronous wheel 5 to rotate. Synchronous wheel 5 transmits power to synchronous wheel 6 through synchronous belt 3. Synchronous wheel 6 drives the gear coaxial with it to rotate through the transmission shaft. Since the rack is fixed to the upper end of the top plate, the gear and rack are meshed. The rotational motion of the gear will be converted into linear motion along the length of the rack, which in turn drives slider 3, where the gear is located, to slide back and forth along the guide rail 3 at the lower end of the top plate. The reciprocating motion of slider 3 directly drives the vertical printing wheel installed at its lower end to move synchronously. The base plate is fixedly set directly below the vertical printing wheel. The fabric passes between the vertical printing wheel and the base plate. The vertical printing wheel completes the printing processing on the fabric width direction during the reciprocating movement.
[0021] As a further preferred embodiment, the top plate 511 is provided with height adjustment mechanisms 54 on both sides. A screw jack structure is adopted, with the fixed end connected to the frame and the telescopic end fixed to both sides of the top plate. Through the telescopic movement of the adjustment mechanism, the top plate is driven to rise and fall vertically, thereby changing the height of the upper power assembly two and the vertical printing wheel fixed to the top plate, thus adjusting the distance between the vertical printing wheel and the base plate.
[0022] As a further preferred embodiment, the frame 1 is also provided with a tension adjustment assembly 6, which includes a motor 61, a synchronous pulley set 62, a drive shaft 63, a vertical screw 64, a tension roller 65, a vertical support 66, and a slider 67. The slider 67 is fixed to both sides of the tension roller 65 and is slidably mounted on the vertical support 66, which is fixed to the frame 1. The slider 67 is mounted on the vertical screw 64 by a nut. A bevel gear at the bottom of the vertical screw 64 meshes with another set of bevel gears on the drive shaft 63. The motor 61 synchronously drives the drive shaft 63 to rotate via the synchronous pulley set 62.
[0023] After the motor starts, it transmits power to the drive shaft through the synchronous belt pulley set, causing the drive shaft to rotate. The bevel gears at both ends of the drive shaft mesh with the bevel gear at the bottom of the vertical screw, converting the horizontal rotation of the drive shaft into the vertical rotation of the vertical screw. When the vertical screw rotates, the slider four, which is engaged with it through the nut, will move up and down along the vertical support, thereby driving the tension roller, which is fixedly connected to the slider four, to move up and down synchronously. The tension roller and the transmission guide roller set work together. When the tension roller rises, the tension increases; when the tension roller falls, the tension decreases.
[0024] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
