Description

Technical Field

[0001] This application relates to the field of printing press technology, and in particular to a printing press waste liquid collection device. Background Technology

[0002] In modern industrial production, printing presses, as one of the most important pieces of equipment, are widely used in the labeling and pattern printing of various products, greatly improving their aesthetics and recognizability, and promoting the marketization of products across industries. With the continuous growth of societal demand for printed materials, printing press technology is also constantly developing, becoming increasingly powerful and capable of high-precision, high-speed printing operations to meet the needs of production of different scales and types, playing an irreplaceable role in many fields such as packaging, publishing, and advertising.

[0003] In traditional printing press operations, conveyor belts or rollers are typically used to transport materials to the printing area, where printheads then perform inkjet printing. However, during the printing process, the ink ejected may exceed the surface area of ​​the material due to various reasons, leading to waste liquid that can easily pollute the environment and even the machine, resulting in resource waste. Utility Model Content

[0004] This application provides a waste liquid collection device for printing presses, which solves the problem that current printing presses may spray out excess waste liquid, causing easy environmental pollution.

[0005] A printing press waste liquid collection device, comprising:

[0006] The base is hollow inside;

[0007] A conveying assembly is disposed within the base, and the upper end of the conveying assembly is capable of abutting against the material and driving the material to move along the length direction;

[0008] The printing body is located at the upper end of the base and is capable of inkjet printing and printing on the material on the conveying assembly;

[0009] A material collection component is provided on the base, and the material collection component is capable of collecting excess waste liquid.

[0010] By adopting the above technical solution, the receiving component, conveying component, and printing body are linked to collect waste liquid simultaneously during the printing process, preventing waste liquid from dripping onto the base or working environment. The conveying component continuously moves the material, working in conjunction with the receiving component to collect waste liquid in real time, realizing an integrated printing-collection process. This not only reduces waste liquid pollution to the environment but also improves the operating efficiency and cleanliness of the printing press, making it suitable for mass production scenarios (such as packaging printing).

[0011] In one embodiment, the base is composed of a base plate, two first side plates and two second side plates. The two first side plates extend along the length direction and are spaced apart along the width direction. The two second side plates extend along the width direction and are spaced apart along the length direction. The printing body is fixed to the first side plates and can rotate.

[0012] By adopting the above technical solution, the printing body can be quickly covered for inkjet printing when needed, and can be quickly separated when not in use, which improves the flexibility and ease of operation of the equipment and makes it easier to clean the printing nozzle or replace the waste liquid collection component.

[0013] In one embodiment, the conveying assembly includes a plurality of conveying members, each extending along the width direction and having its two ends rotatably fixed to the first side plate. The plurality of conveying members are spaced apart along the length direction, and the upper end of each conveying member can abut against the material and convey it along the length direction.

[0014] By adopting the above technical solution, the arrangement of multiple conveyor components ensures continuous material transport and improves production efficiency. The conveyor components extend along the width direction, ensuring the stability of material transport. Both ends of the conveyor components are rotatably fixed to the first side plate, facilitating maintenance and replacement.

[0015] In one embodiment, the conveying component includes a first motor, a drive shaft, and a conveying roller. The first motor is mounted on one of the first side plates. One end of the drive shaft is fixed to the first motor, and the other end is rotatably fixed to the other first side plate. The conveying roller is sleeved on the drive shaft, and the first motor is capable of rotating the drive shaft and the conveying roller.

[0016] By adopting the above technical solution, the specific structural design of the conveying component (including the first motor, drive shaft, and conveying roller) ensures that the material can be transported smoothly. The first motor drives the drive shaft and conveying roller to rotate, allowing the material to come into contact with the upper end of the conveying roller and be transported, thus improving conveying efficiency and stability.

[0017] In one embodiment, the receiving assembly includes multiple receiving seats and multiple receiving components. The receiving seats are hollow inside and the receiving components are disposed in the corresponding receiving seats. The receiving seats extend in the width direction and are fixed at both ends to the first side plate. The receiving seats are disposed between two adjacent conveying components, and the receiving components are capable of absorbing waste liquid.

[0018] By adopting the above technical solution, the arrangement of multiple receiving seats and receiving components forms a multi-point collection system, improving the efficiency of waste liquid collection. The receiving seats are located between adjacent conveying components, making full use of space and preventing waste liquid from dripping directly into the base. The receiving components can absorb the waste liquid, preventing it from flowing directly into the base and causing pollution.

[0019] In one embodiment, the receiving assembly further includes a movable member that extends along the width direction and is fixed to the first side plate. The movable member is located at the lower end of the receiving seat and is fixed to the receiving seat. The first side plate is provided with a fixing groove that corresponds to the receiving seat along the width direction. The movable member is capable of moving the receiving seat along the width direction and extending out of the fixing groove.

[0020] By adopting the above technical solution, the design of the movable component allows the receiving seat to move along the width direction and extend out of the fixing slot, facilitating the replacement of the receiving component from the side of the base. This design avoids the hassle of needing to open the printing body for replacement, saving time and manpower.

[0021] In one embodiment, the movable component includes a guide rail and a slider, the guide rail extending in the width direction and having its two ends fixed to the first side plate, and the slider disposed on the guide rail and fixed to the receiving seat.

[0022] By adopting the above technical solution, the specific structural design of the moving component (including the guide rail and slider) further optimizes the movement performance of the receiving seat. The cooperation between the guide rail and slider ensures the smooth movement of the receiving seat, improving the convenience and reliability of operation.

[0023] In one embodiment, the receiving assembly further includes a sensor disposed between the receiving seat and the moving member.

[0024] By adopting the above technical solution, the addition of sensors enables the device to monitor parameters such as the weight of the receiving seat and the receiving component in real time. This design facilitates timely replacement of the receiving component before it becomes saturated, preventing waste liquid overflow and improving the intelligence level and operating efficiency of the equipment.

[0025] In one embodiment, the receiving seats are provided in two and extend along the length direction. The receiving assembly also includes a telescopic member. The receiving seats are disposed on the telescopic member and close to the corresponding first side plate. The telescopic member is capable of moving the receiving seats along the width direction.

[0026] By adopting the above technical solution, compared with the receiving seat set along the width direction, the receiving seat extending along the length direction can be set at both ends of the material along the width direction, thereby blocking excess gaps and preventing contamination caused by waste ink. The design of the telescopic component allows the receiving seat to move along the width direction, further improving the flexibility and ease of operation of the material receiving assembly.

[0027] In one embodiment, the telescopic member includes a fixed plate, a sliding plate, and a cylinder. The fixed plate extends along the width direction and is fixed at both ends to the first side plate. The sliding plate is disposed on the fixed plate and fixed to the receiving seat. The cylinder is disposed on the fixed plate and connected to the sliding plate. The cylinder is capable of telescoping to move the sliding plate and the receiving seat along the width direction.

[0028] By adopting the above technical solution, the specific structural design of the telescopic component (including the fixed plate, sliding plate, and cylinder) makes the movement of the receiving seat smoother and more reliable. The telescopic function of the cylinder allows the sliding plate and the receiving seat to move along the width direction, further optimizing the replacement process of the receiving component.

[0029] In summary, this application includes at least one beneficial effect:

[0030] 1. The material receiving component works in conjunction with the conveying component and the printing unit to collect waste liquid simultaneously during the printing process, preventing waste liquid from dripping onto the base or the working environment. The conveying component continuously moves the material, working in conjunction with the material receiving component to collect waste liquid in real time, realizing an integrated printing-collection process. This not only reduces waste liquid pollution to the environment but also improves the operating efficiency and cleanliness of the printing press, making it suitable for mass production scenarios (such as packaging printing).

[0031] 2. The arrangement of multiple receiving seats and receiving components forms a multi-point collection system, improving waste liquid collection efficiency. The receiving seats are positioned between adjacent conveying components, making full use of space and preventing waste liquid from dripping directly into the base. The receiving components absorb the waste liquid, preventing it from flowing directly into the base and causing contamination.

[0032] 3. Compared to a receiving seat positioned along the width direction, a receiving seat extending along the length direction can be positioned at both ends of the material along the width direction, thereby blocking excess gaps and preventing ink contamination. The telescopic design allows the receiving seat to move along the width direction, further improving the flexibility and ease of operation of the receiving assembly. Attached Figure Description

[0038] The following is in conjunction with the appendix Figs. 1-4 The waste liquid collection device for printing presses provided in this application will be described in further detail.

[0039] Example 1

[0040] Please see Figs. 1-4 The printing press waste liquid collection device provided in this application includes a base 1, a conveying component 2, a printing body 3, and a receiving component 4.

[0041] like Figs. 1-2 As shown, the base 1 is hollow inside. Specifically, the base 1 is composed of a base plate 11, two first side plates 12, and two second side plates 13. The two first side plates 12 extend along the length direction and are spaced apart along the width direction, and the two second side plates 13 extend along the width direction and are spaced apart along the length direction. The base plate 11 is usually made of metal, which has good strength and stability. Steel plates can be used, or high-strength plastic materials can be used to reduce the overall weight while ensuring a certain strength. The first side plates 12 and the second side plates 13 can also be made of metal or plastic. They are spliced ​​together with the base plate 11 by welding, bolting, or other methods to form a hollow internal structure, providing installation space for components such as the conveying assembly 2.

[0042] The conveying assembly 2 is located within the base 1. The upper end of the conveying assembly 2 can abut against the material and drive the material to move along its length. Specifically, the conveying assembly 2 includes multiple conveying components 21, each extending along its width and with both ends rotatably fixed to the first side plate 12. These multiple conveying components 21 are spaced apart along their length, and the upper end of each conveying component 21 can abut against the material and convey it along its length. In this embodiment, the conveying component 21 includes a first motor 211, a drive shaft 212, and a conveying roller 213. The first motor 211 is mounted on one of the first side plates 12. The motor housing is generally made of cast iron or aluminum alloy, providing good heat dissipation and protection. Alternatively, some new composite materials can be used. The positions of the first motors 211 on adjacent conveying components 21 can be different. One end of the drive shaft 212 is fixed to the first motor 211, typically connected by a coupling. The coupling can be an elastic coupling, effectively buffering vibrations and impacts during transmission. The other end is rotatably fixed to another first side plate 12, and rotation can be achieved through bearings, such as deep groove ball bearings. The conveyor roller 213 is fitted with the drive shaft 212. The conveyor roller 213 is generally made of rubber or similar materials, with a certain degree of friction on its surface, which helps to better move the material. It can also be made of polyurethane or similar materials to improve wear resistance and corrosion resistance. The first motor 211 drives the drive shaft 212 and the conveyor roller 213 to rotate, allowing the material to come into contact with the upper end of the conveyor roller 213 and be transported. Multiple conveying components 21 work together to ensure the stability and continuity of material conveying. In addition, the conveying assembly 2 may also include a feed roller 22 and a discharge roller 23. The feed roller 22 and discharge roller 23 are respectively located on the upper ends of two second side plates 13, such that the height of the second side plates 13 is less than the height of the first side plate 12. At this time, the material can extend downwards from the upper end and abut against the lower end of the feed roller 22, then abut against the upper end of the conveyor component 21 along its length, and finally be discharged by abutting against the discharge roller 23. The material can be paper, plastic, or similar materials.

[0043] The printing body 3 is located on the upper end of the base 1 and is capable of inkjet printing on the material on the conveying assembly 2. Specifically, the printing body 3 is fixed to the first side plate 12 and can rotate. One end of the printing body 3 is hinged to one of the first side plates 12. The hinge can be a structure such as a hinge, which is generally made of metal and has good rotation performance. The other end is snapped to the other first side plate 12. For example, it can be made by using a receiving seat 41 and a locking block to facilitate rotation and closing with the base 1 for inkjet printing during use, and rotation and separation when not in use.

[0044] The receiving assembly 4 is located on the base 1. The receiving assembly 4 effectively collects excess waste liquid that has not been sprayed onto the material, thus preventing contamination of the base 1. Specifically, the receiving assembly 4 includes multiple receiving seats 41 and multiple receiving components 42. The receiving seats 41 are hollow, and the receiving components 42 are located within their corresponding receiving seats 41. The receiving seats 41 extend along their width and are fixed at both ends to the first side plate 12. The receiving seats 41 are generally made of metal, such as stainless steel, which has corrosion-resistant properties. Alternatively, they can be made of engineering plastic to reduce weight. In this embodiment, the receiving seats 41 are located between two adjacent conveying components 21 and have a trapezoidal structure with a larger upper end and a smaller lower end. The height of the receiving seats 41 is less than the height of the conveying rollers 213 to prevent the receiving seats 41 from contacting the material and causing problems. The receiving components 42 can absorb waste liquid. The receiving components 42 can be made of absorbent materials such as sponges or specialized absorbent felts, which can quickly and effectively absorb excess waste liquid.

[0045] The implementation principle of this embodiment is as follows: Through a reasonable structural design, the base 1 of this printing press waste liquid collection device provides stable support and installation space for the entire device. The conveying component 2 can stably drive the material movement, ensuring the smooth progress of the printing operation. The printing body 3 can rotate flexibly, facilitating use and maintenance. The material collection component 4 can collect excess waste liquid, effectively avoiding environmental pollution of the base 1, improving the efficiency and quality of waste liquid collection, and facilitating subsequent treatment and recycling of the waste liquid.

[0046] Example 2

[0047] like Fig. 3As shown, the difference between this embodiment and the above embodiment is that the receiving assembly 4 further includes a moving part 43. The moving part 43 is located at the lower end of the receiving seat 41 and fixed to the receiving seat 41. At this time, the receiving seat 41 is fixed to the first side plate 12 through the moving part 43. The first side plate 12 is provided with a fixing groove 121, which corresponds to the receiving seat 41 along the width direction. The moving part 43 can move the receiving seat 41 along the width direction and extend out of the fixing groove 121. In this embodiment, the moving part 43 includes a guide rail 431 and a slider 432. The guide rail 431 extends along the width direction and is fixed to the first side plate 12 at both ends. The guide rail 431 is a linear guide rail 431, which has high precision and high load-bearing capacity. The slider 432 is located on the guide rail 431 and fixed to the receiving seat 41. The slider 432 can slide freely on the guide rail 431, driving the receiving seat 41 to move and extend out of the fixing groove 121. It is more convenient to replace the receiving part 42 from the side of the base 1, avoiding the time waste caused by opening the printing body 3. The slider 432 is concave and fits against both ends of the guide rail 431 along its length, making it difficult for the slider 432 to extend out of the fixing groove 121 due to contact with the first side plate 12. In one embodiment, the slider 432 can be fixed to the middle of the receiving seat 41, so that only part of the receiving seat 41 can extend out of the fixing groove 121. In another embodiment, there are two sliders 432, which are respectively located at both ends of the receiving seat 41 along its width. The slider 432 closer to the fixing groove 121 is not fixed to the receiving seat 41 and only serves a supporting function. The slider 432 farther from the fixing groove 121 is fixed to the receiving seat 41, which serves both a supporting function and can also extend the receiving seat 41 out of the fixing groove 121.

[0048] The receiving assembly 4 may also include a sensor and a controller. The sensor is located between the receiving seat 41 and the moving part 43. The sensor may be a weight sensor, which can monitor parameters such as the weight of the receiving seat 41 and the receiving part 42 and send the signal to the controller. The controller then controls the slider 432 to move, so that the receiving part 42 can be replaced in time before it is difficult to absorb waste ink.

[0049] The implementation principle of this embodiment is as follows: through the design of the moving part 43 and sensors, the receiving part 42 can be taken out from the side of the base 1 without opening the printing body 3, which facilitates replacement and management and further improves the efficiency and quality of waste liquid collection.

[0050] Example 3

[0051] like Fig. 4 As shown, the difference between this embodiment and the above embodiment is that: there are two receiving seats 41 and they extend along the length direction. At this time, the receiving seats 41 are located at the lower end of the conveying member 21. The receiving assembly 4 also includes a telescopic member 44. The receiving seats 41 are located on the telescopic member 44 and close to the first side plate 12 corresponding to it. The telescopic member 44 can move the receiving seats 41 along the width direction.

[0052] In this embodiment, the telescopic component 44 includes a fixed plate 441, a sliding plate 442, and a cylinder 443. The fixed plate 441 extends along the width direction and is fixed at both ends to the first side plate 12. The fixed plate 441 is generally made of metal tubing, which has high strength and stability. The fixed plate 441 is provided with two spaced intervals along the length direction for better support. The sliding plate 442 is disposed on the fixed plate 441 and fixed to the receiving seat 41. The sliding plate 442 is inclined L-shaped and can slide on the fixed plate 441, serving to support and drive the receiving seat 41 to move. The cylinder 443 is disposed on the fixed plate 441 and connected to the sliding plate 442. The cylinder 443 can be a pneumatic cylinder 443, which realizes the telescopic action by compressed air, or it can be an electric cylinder 443, which has higher control precision. The cylinder 443 can also be other structures that can control the movement of the sliding plate 442. At this time, the first side plate 12 is provided with a corresponding fixing hole 122. The cylinder 443 can extend and retract to move the sliding plate 442 and the receiving seat 41 along the width direction and extend them out of the fixing hole 122, further facilitating the replacement and maintenance of the receiving part 42. Moreover, there is a gap between the side wall of the sliding plate 442 and the side wall of the receiving seat 41, so that when the upper end of the sliding plate 442 abuts against the upper end of the fixing hole 122, the receiving seat 41 can be located outside the first side plate 12, and the sliding plate 442 will not tilt or even fall off. Similarly, a gravity sensor is provided in the sliding plate 442. When the gravity is detected to reach a preset threshold, a signal is sent to the controller, and the controller controls the cylinder 443 to run. In addition, an alarm can also be provided. When the controller controls the cylinder 443 to run, it also controls the alarm to sound, so as to remind personnel to replace it in time.

[0053] In addition, protective shells can be provided at both ends of the conveyor 21 along the width direction. The protective shells and the corresponding first side plates 12 are fixed and made of hydrophobic material, which allows the waste ink falling on the conveyor 21 to flow smoothly downward and enter the receiving seat 41, avoiding any impact.

[0054] The implementation principle of this embodiment is as follows: by setting up receiving seats 41 on both sides of the material along the width direction, most of the excess waste liquid sprayed out by the printing body 3 can enter the receiving seat 41 and be absorbed by the receiving component 42. This avoids the difficulty of the receiving component 42 located at the lower end of the material when it is set between the conveying components 21, thereby enabling it to function throughout the entire range of the receiving component 42 and increasing the usable area of ​​the receiving component 42. At the same time, the telescopic component 44 can also move the receiving seat 41 along the width direction, making it convenient to replace the receiving component 42 in a timely manner.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
