Description

Technical Field

[0001] This utility model relates to the field of digital printing, and in particular to an anti-lifting device for fabric processing. Background Technology

[0002] During digital printing production, the fabric may be lifted due to the rapid operation of the conveyor belt, changes in the fabric's own tension, and external airflow. As a critical and precise component, the printhead is easily damaged or malfunctions when it is impacted by the fabric. This not only affects the normal operation of production but also leads to high maintenance and replacement costs. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-lifting device for fabric processing. When the fabric tends to lift, the anti-lifting device will block and restrain it, ensuring that the range of fabric lifting does not exceed a given height. This isolates the fabric from the nozzle in space, fundamentally eliminating the possibility of the fabric hitting the nozzle. It provides a strong guarantee for the safe operation of the nozzle and the stable transmission of the fabric during the production process, thereby solving the problems mentioned in the background art.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] An anti-lifting device for fabric processing includes a fabric anti-lifting rod and a connecting assembly. The connecting assembly includes a bending mounting plate, a connecting piece rotatably mounted on the inner cavity sidewall of the bending mounting plate, the fabric anti-lifting rod mounted on the connecting piece, a short cylindrical portion rotatably mounted on the outer end face of the bending mounting plate, a limiting portion one provided at the lower end of the connecting piece, a stop post mounted on the inner cavity sidewall of the bending mounting plate, the limiting portion one being able to abut against the stop post, and a safety limit sensing component mounted on the inner cavity sidewall of the bending mounting plate, which performs a stop protection when the fabric anti-lifting rod is lifted to a large extent.

[0006] Preferably, the safety limit sensing component includes a micro-motion limit switch, on which an elastic actuator is provided, and the elastic actuator abuts against the limiting part two of the connecting piece.

[0007] Preferably, the bending mounting plate is provided with a second strip groove, and the micro-motion limit switch is adjustablely installed in the second strip groove.

[0008] Preferably, the bending mounting plate is provided with a strip groove, and the stop post is adjustablely installed in the strip groove.

[0009] Preferably, a bearing is installed between the connecting piece and the inner cavity sidewall of the bent mounting plate.

[0010] The advantages and positive effects of this utility model are:

[0011] This invention utilizes a slightly movable fabric anti-lifting rod and a fixed short cylinder to dynamically press and cover the fabric without damaging it. This effectively resists fabric lifting caused by tension changes, static electricity, or airflow, ensuring a constant distance between the printhead and the fabric during printing. This fundamentally guarantees printing quality. When the fabric tends to lift, the anti-lifting device blocks and restrains it, ensuring that the lifting range never exceeds a given height. This spatially isolates the fabric from the printhead, fundamentally eliminating the possibility of the fabric touching the printhead. This provides strong protection for the safe operation of the printhead and the stable transmission of the fabric during production. Attached Figure Description

However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of at least two components or the interaction relationship of at least two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. The embodiments of this invention are further described in detail below with reference to the accompanying drawings:

[0023] Please see Figure 1-6 This utility model provides an embodiment of an anti-lifting device for fabric processing, comprising an anti-lifting rod 1 and two connecting components 2. The anti-lifting rod 1 is rotatably mounted between the two connecting components 2. Each connecting component 2 includes a bending mounting plate 21, the outer side of which is enclosed by a sheet metal bending cover 22. A connecting piece 23 is rotatably mounted on the inner wall of the bending mounting plate 21. The anti-lifting rod 1 is bolted to the upper end of the connecting piece 23. A short cylindrical portion 3 is rotatably mounted on the outer end face of the bending mounting plate 21. The fabric is then printed. The short cylindrical section 3 and the fabric anti-lifting rod 1 are used for limiting and preventing lifting. The short cylindrical section 3 is fixed in position, while the fabric anti-lifting rod 1 has a certain degree of mobility. A limiting part 25 is provided at the lower end of the connecting piece 23, and a stop post 26 is installed on the inner cavity side wall of the bending mounting plate 21. The limiting part 25 can abut against the stop post 26, thereby forming a fixed limit on the rotation of the connecting piece 23. At the same time, a safety limit sensing component is installed on the inner cavity side wall of the bending mounting plate 21 to stop the machine for protection when the fabric anti-lifting rod 1 is lifted to a large extent.

[0024] It should be noted that, in this embodiment, the safety limit sensing component includes a micro-motion limit switch 27, on which an elastic actuator 28 is provided. The elastic actuator 28 abuts against the limiting part 24 of the connecting piece 23. Once the fabric anti-lifting rod 1 is lifted too much, it will drive the connecting piece 23 to rotate towards the micro-motion limit switch 27, thereby causing the limiting part 24 to press against the elastic actuator 28, thus triggering the on / off state of the contact.

[0025] It should also be noted that, in order to facilitate the adjustment of the movement range of the fabric anti-lifting rod 1, in this embodiment, the bending mounting plate 21 is provided with a second strip groove 30, the micro-motion limit switch 27 is adjustablely installed in the second strip groove 30, the bending mounting plate 21 is provided with a first strip groove 29, and the stop post 26 is adjustablely installed in the first strip groove 29, which greatly facilitates the adjustment of the rotation range of the connecting piece 23, so that the fabric anti-lifting rod 1 can be adapted to fabrics of different thicknesses, thereby achieving the best anti-lifting state.

[0026] In another embodiment, a bearing 31 is installed between the connecting piece 23 and the inner cavity sidewall of the bent mounting plate 21, effectively ensuring one rotation of the connecting piece 23.

[0027] In practice, the device is fixed on the main frame, with the guide belt below the device and above the fabric processing device. One or more guide belts can be installed at the front and rear positions of the nozzle area. The fabric is located below the fabric anti-lifting rod 1, and both ends of the fabric are embedded between the fabric anti-lifting rod 1 and the short cylinder 3. At this time, the fabric anti-lifting rod 1 presses down on the moving fabric to prevent it from lifting due to tension changes, static electricity, or airflow, keeping the fabric and guide belt in close contact and ensuring a constant distance between the nozzle and the fabric surface. Once the fabric tends to lift, the fabric anti-lifting rod 1 will move upward, causing the connecting piece 23 to rotate and squeeze the elastic actuator piece 28. At the same time, the bottom will be further limited by the stop post 26 to completely prevent the fabric from lifting.

[0028] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
