Description

Technical Field

[0001] This utility model relates to the technical field of medical film processing equipment, and in particular to a CT film printing roller. Background Technology

[0002] In the field of medical imaging diagnosis, CT film, as the core carrier of lesion image information, directly determines the image clarity and diagnostic accuracy through its printing quality. The CT film printing roller is a key component in the printing equipment that enables film transfer and pressure penetration. Through the roller's contact and rotation with the film, the printing liquid is evenly pressed onto the film coating, ensuring sufficient silver halide reaction and complete image details. Existing CT film printing rollers often have a single structure or insufficient interlayer bonding strength. The elastic layer is prone to detachment and displacement during long-term high-speed rotation, and there is a lack of effective elastic buffer structure, resulting in uneven pressure distribution on the film from the roller, making the film prone to creases and damage. At the same time, the roller surface has poor wear resistance and anti-stick properties, resulting in a large amount of residual liquid adhering to it, which directly affects the clarity and integrity of the printed film. Furthermore, it is impossible to dynamically adjust the pressure between the roller and the film according to the thickness of different CT film specifications, resulting in poor compatibility with different film specifications. In addition, there is a lack of efficient cleaning and recovery mechanisms for residual liquid and impurities on the roller surface, requiring frequent shutdowns for manual cleaning, which significantly reduces the efficiency of the printing operation. Utility Model Content

[0003] This utility model relates to a CT film printing roller, which addresses the problems mentioned in the background art. These problems include: existing CT film printing rollers often have a single-layer structure or insufficient interlayer bonding strength; the elastic layer is prone to detachment and displacement during long-term high-speed rotation; there is no effective elastic buffer; uneven pressure on the film from the roller leads to creases and damage; the roller surface has poor wear resistance and anti-stick properties, resulting in excessive chemical residue that affects the clarity and integrity of the printed film; the inability to dynamically adjust pressure according to the thickness of different CT films leads to poor compatibility; and the lack of an efficient cleaning and recovery mechanism for chemicals and impurities on the roller surface requires frequent machine shutdowns for manual cleaning, significantly reducing printing efficiency.

[0004] This utility model provides a CT film printing roller, specifically including: a roller shaft body; a roller shaft sleeve layer is sleeved on the outer side of the roller shaft body, and two adjusting rings are symmetrically threaded to the left and right ends of the roller shaft body. Adjusting bearings are slidably connected to the outer side of the adjusting rings, and the adjusting bearings are installed inside the control seat. The bottom of the control seat is slidably connected to the upper side of the device mounting base.

[0005] Furthermore, the left and right ends of the roller body are provided with external threads, and the inner sidewall of the connecting end of the adjusting ring and the roller body is provided with internal threads, and the internal threads and external threads are connected.

[0006] Furthermore, the innermost layer of the roller sleeve layer is an inner core layer, and an annular groove is provided at equal intervals on the outer side wall of the inner core layer. An elastic layer is provided on the outer side of the inner core layer, and the inner side of the elastic layer is attached to the outer side of the inner core layer and engaged in the annular groove. A functional layer is provided on the outer side of the elastic layer.

[0007] Furthermore, an adjusting shaft is fixedly connected to the middle of the opposite sidewalls of the two adjusting rings. A sliding groove is provided at equal intervals on the outer sidewall of the adjusting shaft. The adjusting bearing is slidably connected to the adjusting shaft, and the adjusting bearing on the opposite side of the two adjusting rings is rotatably connected to the control seat.

[0008] Furthermore, the control base is symmetrically arranged, and sliding rods are symmetrically installed at the bottom of the control base. The sliding rods are slidably connected through the device mounting base, and a pressure spring is sleeved on the sliding rod on the lower side of the device mounting base.

[0009] Furthermore, a cleaning scraper is fixedly connected to the middle of the rear side wall of the control seat. The top front end of the cleaning scraper is inclined and attached to the rear side of the roller sleeve layer. A groove is provided at the bottom of the cleaning scraper, and a recycling pipe is connected to the rear end of the groove.

[0010] This utility model provides a CT film developing roller, which has the following beneficial effects:

[0011] 1. In the layered design of the roller sleeve, the annular groove of the inner core layer strengthens the connection with the elastic layer, preventing the elastic layer from falling off or shifting during long-term high-speed rotation. The rubber elastic layer can buffer pressure through its own elasticity, making the pressure of the roller on the film evenly distributed. This fundamentally avoids creases and damage to the film due to excessive local stress. The functional layer can be flexibly set to wear-resistant or non-stick properties according to needs, which reduces the risk of friction damage between the roller and the film and reduces the adhesion of residual chemicals, ensuring the clarity and integrity of the film printing. At the same time, the combination of the sliding rod and pressure spring at the bottom of the control seat can effectively absorb the working vibration of the roller and reduce operating noise. It also allows the control seat to dynamically and adaptively adjust according to the film thickness, significantly improving the compatibility with different specifications of CT films. The cooperation of the cleaning scraper and the recovery tube can scrape off the chemicals and impurities on the surface of the roller sleeve in real time and direct them out, keeping the roller clean and reducing the frequency of equipment cleaning and maintenance, further improving the overall printing efficiency.

[0012] 2. The main body of the roller is made of stainless steel, whose excellent corrosion resistance and high strength can effectively resist the erosion of printing chemicals, ensuring structural stability during long-term use. At the same time, it provides solid support for the roller sleeve, ensuring that the overall rigidity of the roller meets the printing operation standards. On the other hand, through the precise engagement of the adjusting ring with the internal and external threads of the roller body, not only can the axial position of the roller body be finely adjusted to meet the position requirements of different printing scenarios, but it also greatly improves the ease of disassembly and replacement of the roller body, significantly shortening equipment maintenance time. In addition, the sliding engagement between the groove on the outer wall of the adjusting shaft and the adjusting bearing facilitates the quick assembly of the adjusting ring and ensures the synchronization of the adjusting ring and the adjusting bearing during rotation, avoiding jamming or misalignment, further improving the stability of equipment operation.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides a CT film developing roller, comprising: a roller shaft body 1, a roller shaft sleeve layer 2 sleeved on the outer side of the roller shaft body 1, two adjusting rings 3 symmetrically threaded at the left and right ends of the roller shaft body 1, adjusting bearings 4 slidably connected to the outer side of the adjusting rings 3, the adjusting bearings 4 being installed inside a control seat 5, the bottom of the control seat 5 being slidably connected to the upper side of a device mounting seat 6, external threads 101 at the left and right ends of the roller shaft body 1, and internal threads 302 opening in the inner sidewall of the connection end between the adjusting rings 3 and the roller shaft body 1, the internal threads 302 being connected to the external threads 101, and the roller shaft body 1 being made of stainless steel. The stainless steel material combines excellent corrosion resistance, high strength, and rust resistance, effectively resisting the erosion of various chemicals encountered during the printing process, ensuring the structural stability of the roller body 1 for long-term use, and providing solid and reliable support for the roller sleeve 2, ensuring that the overall rigidity of the roller fully meets the usage standards during printing operations. In addition, through the threaded connection between the two adjusting rings 3 and the roller body 1, the precise cooperation between the internal thread 302 and the external thread 101 not only enables fine adjustment of the axial position of the roller body 1, but also greatly improves the convenience of disassembling and replacing the roller body 1, reducing equipment maintenance time.

[0027] Among them, the innermost layer of the roller sleeve layer 2 is the inner core layer 201. Annular grooves are formed at equal intervals on the outer wall of the inner core layer 201. An elastic layer 202 is provided on the outer side of the inner core layer 201. The elastic layer 202 is made of rubber and is injection molded and bonded to the annular grooves of the inner core layer 201. The inner side of the elastic layer 202 is bonded to the outer side of the inner core layer 201 and engaged in the annular grooves. A functional layer 203 is provided on the outer side of the elastic layer 202. Specifically, the annular grooves on the outer side of the inner core layer 201 not only significantly improve the bonding strength with the elastic layer 202, but also... It can effectively prevent the elastic layer 202 from falling off or shifting during long-term high-speed rotation. The rubber elastic layer 202 can form an effective buffer during the printing process through its own elasticity, so that the pressure of the roller on the film is evenly distributed. This fundamentally avoids problems such as creases and damage to the film due to excessive local stress. The functional layer 203 can be flexibly set to wear-resistant or non-stick properties according to actual printing needs. This can reduce the risk of friction damage between the roller and the film, and reduce the amount of chemical residue adhering to the roller surface, effectively ensuring the clarity and integrity of the film printing.

[0028] An adjusting shaft 301 is fixedly connected to the middle of the opposite sidewalls of the two adjusting rings 3. Sliding grooves are provided at equal intervals on the outer sidewall of the adjusting shaft 301. An adjusting bearing 4 is slidably connected to the adjusting shaft 301. The adjusting bearing 4 on the opposite side of the two adjusting rings 3 is rotatably connected to the control seat 5. The control seats 5 are symmetrically arranged, and sliding rods 501 are symmetrically installed at the bottom of the control seats 5. The sliding rods 501 are slidably connected to the device mounting seat 6. A pressure spring 502 is sleeved on the sliding rod 501 on the lower side of the device mounting seat 6. Specifically, the adjusting shaft... The sliding groove on the outer wall of 301 and the sliding fit structure of the adjusting bearing 4 not only greatly improves the ease of disassembly and assembly of the adjusting ring 3, but also ensures the synchronization of the adjusting ring 3 and the adjusting bearing 4 when rotating, avoiding jamming or misalignment. The combined design of the sliding rod 501 and the pressure spring 502 can effectively absorb the vibration generated during the operation of the roller shaft, reduce the operating noise of the equipment, and at the same time enable the control seat 5 to dynamically and adaptively adjust its position according to the film thickness, ensuring that the roller shaft and the film always maintain a matching pressure, significantly improving the compatibility of the device with different specifications of CT films.

[0029] A cleaning scraper 503 is fixedly connected to the middle of the rear side wall of the control seat 5. The front top of the cleaning scraper 503 is inclined and attached to the rear side of the roller sleeve layer 2. A groove is opened at the bottom of the cleaning scraper 503, and a recovery pipe 504 is connected to the rear end of the groove. Specifically, the cleaning scraper 503 is in close contact with the surface of the roller sleeve layer 2 in an inclined posture. During the continuous rotation of the roller, it can scrape off the residual printing liquid and fine impurities on the surface of the roller sleeve layer 2 in real time, preventing contaminants from being transferred to the film surface with the rotation of the roller, thereby ensuring the quality stability of film printing. The cooperation structure between the groove at the bottom of the cleaning scraper 503 and the recovery pipe 504 can collect and direct the scraped contaminants in a timely manner, which is convenient for subsequent centralized treatment. It can not only maintain the cleanliness of the surface of the roller sleeve layer 2, but also reduce the frequency and workload of equipment cleaning and maintenance, and further improve the overall printing efficiency.

[0030] The specific usage and function of this embodiment are as follows:

[0031] When using this CT film printing roller, first connect and fix the roller body 1 to the internal thread 302 of the adjusting ring 3 via the external threads 101 at both ends, so that the roller sleeve 2 is securely fitted onto the outside of the roller body 1, ensuring that the annular groove of the inner core layer 201 is tightly engaged with the elastic layer 202 and the functional layer 203 faces outward. Then, by rotating the adjusting ring 3, the axial position of the roller body 1 is finely adjusted by the cooperation of the internal thread 302 and the external thread 101. Finally, the sliding cooperation between the sliding groove of the adjusting shaft 301 and the adjusting bearing 4 is used to complete the assembly of the adjusting ring 3 and the control seat 5, so that the control seat 5 can be connected to the roller body 1. The bottom sliding rod 501 is installed on the device mounting base 6. The pressure spring 502 can adaptively adjust the position of the control seat 5 according to the film thickness to ensure that the roller and the film maintain appropriate pressure. During the printing operation, the stainless steel roller body 1 provides stable support, the rubber elastic layer 202 buffers the pressure to avoid film damage, and the functional layer 203 reduces friction and chemical residue. At the same time, the cleaning scraper 503 on the control seat 5 scrapes away contaminants on the surface of the roller sleeve layer 2 in real time. The scraped material is discharged through the groove and the recycling tube 504, realizing stable and high-quality printing of CT films of different specifications.

[0032] Example 2:

[0033] The recovery pipe 504 is equipped with a conical filter screen inside the connection end with the groove. The middle section of the recovery pipe 504 is equipped with a detachable transparent observation section. The inner wall of the observation section is coated with a hydrophobic coating. The conical filter screen can intercept large particles of impurities, preventing the recovery pipe 504 from clogging. The transparent observation section allows for real-time observation of the internal liquid and impurities, enabling timely cleaning. The hydrophobic coating reduces the adhesion of residual medicine, ensuring unobstructed recovery channels, reducing the frequency of downtime maintenance due to pipe blockage, and improving the stability of continuous equipment operation.
