Description

Technical Field

[0001] This utility model belongs to the field of film collection technology, and in particular relates to a film collection structure for cross-cutting medical films. Background Technology

[0002] As a crucial medium for carrying medical imaging information, the collection process after medical film is cut directly affects film quality and production efficiency. Currently, most film cutting devices on the market suffer from insufficient collection accuracy: when the cut film is transported via conveyor belt, the lack of targeted obstruction and positioning structures easily leads to forward and backward misalignment and disordered stacking. During subsequent manual sorting, friction between the films can easily cause surface scratches, affecting image clarity.

[0003] Although some existing collection devices have simple baffles, they have obvious defects: First, the baffles are mostly fixed structures, and the film is prone to accumulate or become disjointed in the front area near the cross-cutting blade; Second, the edges of the blocking components are mostly right-angled structures, which are prone to scratches when in contact with the smooth film surface; Third, the conveying path lacks protective design, and dust and impurities are prone to adhere to the film surface.

[0004] Therefore, it is essential to invent a film collection structure for cross-cutting medical films. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a film collection structure for cross-cutting medical films, comprising a conveyor frame, a conveyor belt, a conveyor motor, a support base, a support plate, a protective top plate, a rear end block, a drive shaft, a drive motor, a connecting plate, and a blocking frame. The conveyor belt is mounted on two rotatably mounted conveyor rollers on the conveyor frame, with one conveyor roller fixedly connected to the output end of a conveyor motor fixedly mounted on the conveyor frame. Two symmetrical support bases and support plates are fixedly mounted on the conveyor frame, with a protective top plate fixedly mounted between the support plates. The rear end block is fixedly mounted at one end of each support plate. A connecting plate is fixedly mounted on the drive shaft rotatably mounted between the support bases, and a blocking frame is fixedly mounted on the connecting shaft. Either end of the drive shaft is fixedly connected to the output end of a drive motor fixedly mounted on one of the support bases.

[0006] Preferably, the support plate is fixedly installed on the conveyor frame and perpendicular to the ground, and the protective top plate is horizontally fixed between the two support plates. The protective top plate is located above the conveyor belt and parallel to the upper surface of the conveyor belt.

[0007] Preferably, a rear end block is fixedly installed at one end of the support plate away from the blocking frame, and the rear end block has an "L" shaped structure. Two oppositely arranged rear end blocks are used to block the film. The rear end blocks are located at the rear end of the conveyor belt. The area above the rear end blocks is not blocked by the protective top plate, which provides a non-obstructed area for the film to be picked up.

[0008] Preferably, there is a space between the protective top plate and the blocking frame, and the space allows the blocking frame to move without interfering with each other. The blocking frame has a "U" shaped structure with rounded corners at its lower end. The blocking frame can be perpendicular to the ground and is used to block the transversely cut film.

[0009] Preferably, the blocking frame is installed at the front end of the conveyor belt and close to the cross-cutting blade of the cross-cutting machine. The front end of the conveyor belt is the input end, and its rear end is the output end.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a U-shaped blocking frame at the front end of the conveyor belt (near the cross-cutting blade) to instantly stop and position the film after cross-cutting. Combined with the dual limiting function of the L-shaped blocking frame at the rear end, it effectively solves the problems of film conveying deviation and disordered stacking in existing devices. The blocking frame, driven by a motor, can adapt to different cutting speeds, preventing film accumulation or separation. Actual testing has shown that it improves the regularity of film collection.

[0011] The protective top plate above the conveyor belt in this invention effectively blocks dust and impurities, reducing the risk of film contamination. It also helps to prevent interference from external airflow. Furthermore, its space design with the rear barrier creates a dedicated, unobstructed area for retrieving the film, preventing damage during manual film handling. The rounded corners at the bottom of the barrier frame reduce friction with the film surface, lowering the rate of film scratches compared to traditional right-angle blocks.

[0012] The non-interference collaborative design of the blocking frame and the protective top plate in this utility model, combined with the rotatable blocking structure that can be precisely controlled by the drive motor, allows the blocking frame to be smoothly retracted and removed from the conveyor path after completing the blocking and positioning of a single batch of film. At this time, the conveyor belt can start normally and transport the batch of cut film smoothly to the rear area for subsequent centralized collection. This effectively connects the film cutting, positioning and batch transfer process, and further improves the continuity of production. Attached Figure Description

[0019] As attached Figure 1 To be continued Figure 3 As shown: This utility model provides a film collection structure for cross-cutting medical films, including a conveyor frame 1, a conveyor belt 2, a conveyor motor 3, a support base 4, a support plate 5, a protective top plate 6, a rear end block 7, a drive shaft 8, a drive motor 9, a connecting plate 10, and a blocking frame 11. The conveyor belt 2 is mounted on two rotatably mounted conveyor rollers on the conveyor frame 1, and one of the conveyor rollers is fixedly connected to the output end of the conveyor motor 3 fixedly mounted on the conveyor frame 1. Two symmetrical support bases 4 and support plates 5 are fixedly mounted on the conveyor frame 1, and a protective top plate 6 is fixedly mounted between the support plates 5. The rear end block 7 is fixedly mounted at one end of each support plate 5. A connecting plate 10 is fixedly mounted on the drive shaft 8 rotatably mounted between the support bases 4, and a blocking frame 11 is fixedly mounted on the connecting plate 10. Either end of the drive shaft 8 is fixedly connected to the output end of the drive motor 9 fixedly mounted on one of the support bases 4.

[0020] Furthermore, the support plate 5 is made of cold-rolled steel plate and is symmetrically fixed to the crossbeams on both sides of the conveyor frame 1 by M6 hexagonal bolts. The support plate 5 is set perpendicular to the ground to ensure structural stability. On the inner sidewalls of the two support plates 5, protective top plates 6 are horizontally fixed by laser welding. The protective top plate 6 is made of 2-3mm thick transparent acrylic sheet (to facilitate observation of the film conveying status). It covers the area above the conveyor belt 2, and the lower surface of the protective top plate 6 maintains a parallel distance of 50-90mm from the upper surface of the conveyor belt 2. This distance can effectively prevent external dust and impurities from falling into the film surface, and also avoid contact and friction between the protective top plate 6 and the conveyor belt 2 and the film, ensuring smooth film transmission, while reducing the interference of direct airflow to a certain extent.

[0021] Furthermore, at one end of the support plate 5 away from the blocking frame 11 (i.e., the side closest to the rear end of the conveyor belt 2), a rear end block 7 is fixedly installed by an M4 countersunk bolt. The rear end block 7 is made of wear-resistant nylon material and is integrally injection molded (to avoid scratching the surface of the film). Its overall structure is "L" shaped. The two rear end blocks 7 are arranged relatively symmetrically, and the horizontal sections of both extend towards the center of the conveyor belt 2. The upper surface of the horizontal section is slightly higher than the upper surface of the conveyor belt 2 by 1-2mm (which can prevent the film from shifting when it is conveyed backward without affecting the smooth transmission of the film). At the same time, the area above where the rear end block 7 is located is not covered by the protective top plate 6, forming a retrieval and clearance area. The width of this area is adapted to the width of the conveyor belt 2, which makes it easy for the operator to reach in and smoothly pick up and put down batches of film, avoiding damage to the film by touching the protective top plate 6 when picking up the film.

[0022] Furthermore, a movable space is reserved between the protective top plate 6 and the blocking frame 11 at one end. The size of this space is adapted to fully accommodate the blocking frame 11 to rotate 360° under the drive shaft 9, ensuring that there is no contact or interference between the two during the movement. The blocking frame 11 is made of lightweight aluminum alloy and the surface is anodized for corrosion protection. Its overall shape is a "U"-shaped opening structure, with the opening facing the front end of the conveyor belt 2 (i.e., the direction of the cross-cutting blade). The two corners at the bottom of the blocking frame 11 are rounded (completely eliminating the risk of sharp edges scratching the film). When the blocking frame 11 rotates to a working state perpendicular to the ground under the drive motor 8, the lower end is 0.5-1mm away from the upper surface of the conveyor belt 2, which can accurately block the film that has just been cross-cut and prevent the film from moving back and forth on the conveyor belt 2.

[0023] Furthermore, the blocking frame 11 is fixed to the connecting plate 10 by welding, and is installed at the front end of the conveyor belt 2. Its central axis coincides with the center line of the width direction of the conveyor belt 2, ensuring more accurate blocking and positioning of the film. The blocking frame 11 is close to the side of the cross-cutting blade of the cross-cutting machine, so that the film can be immediately carried into the blocking area of ​​the blocking frame 11 by the conveyor belt 2, avoiding the film from shifting during the conveying gap. The conveyor belt 2 is made of food-grade polyurethane material (with wear-resistant and anti-slip properties), and its surface is matte-treated to reduce electrostatic adsorption between the film and the belt. The front end of the conveyor belt 2 is defined as the film input end (receiving the cross-cut film), and the rear end is defined as the film output end (transporting batches of film to the rear blocking area 7). The transmission direction of the input end and the output end is kept horizontally consistent to ensure that the film remains stable throughout the entire conveying process.

[0024] The working principle is as follows: First, after the medical film is cut by the cross-cutting machine, it will enter the front input end of the conveyor belt 2. At this time, the conveyor motor 3 starts, drives the conveyor roller on the conveyor frame 1 to rotate, and then drives the conveyor belt 2 to smoothly transmit along the direction of "front input end → rear output end"; at the same time, the drive motor 9 controls the blocking frame 11 to keep it perpendicular to the ground, and prepares the blocking and positioning for receiving the cross-cut film.

[0025] Secondly, after being cut, the individual film sheets move forward with the conveyor belt 2. When the front end of the film sheet contacts the blocking frame 11, the blocking frame 11 will limit the film sheet, preventing it from moving back and forth on the conveyor belt 2 and ensuring that the individual film sheets maintain a regular position on the conveyor belt 2. During this process, the protective top plate 6 covers the conveyor belt 2, which can not only block external dust and impurities from falling onto the film surface, but also reduce the interference of external airflow on the film transmission, ensuring a stable film transmission environment.

[0026] Next, as the cross-cutting machine continues to cut the film, multiple films will be stacked sequentially on the conveyor belt 2 under the limiting action of the blocking frame 11 to form a batch of films, and each film can maintain its position alignment; when the batch of films stacked on the conveyor belt 2 reaches the preset collection quantity, the drive motor 9 starts and drives the drive shaft 8 to rotate. The drive shaft 8 drives the blocking frame 11 to rotate around the drive shaft 8 and retract through the connecting plate 10, so that the blocking frame 11 is completely removed from the transmission path of the conveyor belt 2 and no longer obstructs the film.

[0027] Then, the conveyor belt 2 continues to run in the original transmission direction, conveying the batch of neat film from the front end to the rear end; when the rear end of the batch of film contacts the rear end stop 7, the rear end stop 7 will form a secondary limit on the batch of film, to prevent the film from shifting position due to excessive backward transmission due to inertia, and to ensure that the batch of film remains in a neat state in the rear output area.

[0028] Finally, the operator can smoothly remove the batches of neatly arranged film through the retrieval area above the rear barrier 7, which is not covered by the protective top plate 6. After the film is removed, the drive motor 9 starts again, driving the barrier frame 11 to return to a working state perpendicular to the ground. The conveyor motor 3 maintains or adjusts the transmission state according to the cutting rhythm of the next batch of film by the cross-cutting machine, preparing to receive the collection of the next round of cross-cut film. Through such a cycle, continuous and stable film collection operation is achieved.

[0029] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
