Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to a slitting machine unwinding frame structure that facilitates winding and film splicing. Background Technology

[0002] A slitting machine is a cutting device that cuts wide films into multiple narrow strips of material. Currently, many steps in the winding operation of the slitting machine's master roll (i.e., installing the master roll onto the unwinding device) require manual handling and movement, which is inconvenient. In particular, the winding operation of large master rolls (with large diameters) is even more difficult, time-consuming, and labor-intensive, affecting production efficiency.

[0003] On the other hand, when defective film material is observed during the unwinding process of the slitting machine's master roll, the defective portion of the film material needs to be completely cut off at the splicing table of the slitting machine before splicing the film material. Then, the master roll continues to unwind, removing the defective film material during the unwinding process. Currently, the splicing table on slitting machines is generally fixed on the frame and, to avoid interference with the master roll, is usually located above it. When defective film material is observed, the operator needs to stand in front of the master roll to perform the splicing operation. This means that the operator is obstructed by the master roll while performing the splicing operation at the splicing table, affecting their work. Furthermore, because the splicing table is generally located above the master roll, its position on current slitting machines is relatively high, especially on slitting machines with large master rolls, where the splicing table is even higher, which also affects the operator's splicing operation. For example, Chinese Patent Publication No. CN210064643U, entitled "Slitting Machine Film Joining Device", describes a slitting machine film joining device that is also fixed in place and suffers from the same shortcomings. Utility Model Content

[0004] The purpose of this utility model is to provide a slitting machine unwinding frame structure that not only facilitates the winding operation of the master roll and reduces the manual handling steps of the master roll during the winding operation, but also makes it easier for operators to perform film splicing operations on the film splicing table.

[0005] The technical solution of this utility model is: A slitting machine unwinding frame structure that facilitates unwinding and film splicing includes a frame, an unwinding device, and a film splicing device. The unwinding device includes: The tilting frame is rotatably mounted at the bottom of the machine frame via a horizontal pivot. The unwinding frame for placing the master roll is located on the turning frame; The flipping mechanism drives the flipping frame to rotate around a horizontal axis, so that the master roll on the unwinding frame is raised or lowered. The membrane bonding device includes: The sliding seat is slidably mounted on the frame along the front-to-back direction of the slitting machine and is located at the front of the slitting machine; Two film-coating guide rollers are rotatably mounted on a sliding seat; The film-attaching platform is located on the sliding seat and between the two film-attaching guide rollers; A translation mechanism drives the sliding seat to move. The specific application of this design's unwinding frame structure for a slitting machine, which facilitates film loading and splicing, is as follows. Once the master roll is transported to the designated position in front of the slitting machine, the flipping mechanism drives the flipping frame to rotate around the horizontal axis, causing the unwinding frame to rotate downwards to the designated position, allowing the master roll to be installed onto the unwinding frame without moving or handling. Next, the master roll is installed onto the unwinding frame. Then, the flipping mechanism drives the flipping frame to rotate around the horizontal axis, causing the unwinding frame to rotate the master roll upwards to the designated position, thus achieving automatic winding. This facilitates the winding operation of the master roll and reduces the manual handling steps of the master roll during the winding process.

[0006] On the other hand, during the unwinding process of the master roll, if defective film material is observed being output, the translation mechanism drives the sliding seat to move the splicing table forward to a designated position. Then, when the defective film material is conveyed to the splicing table, the unwinding of the master roll is paused. Next, the defective portion of the film material is completely cut off on the splicing table, and then the film material is spliced. Then, the translation mechanism drives the sliding seat to move the splicing table backward to a designated position, and the master roll continues to unwind. In this way, defective film material in the master roll can be removed. Meanwhile, since the translation mechanism of the film splicing device can drive the sliding seat and the film splicing table to move along the front and back direction of the slitting machine, when a defective film material is observed to be output, the translation mechanism drives the sliding seat to move the film splicing table forward to the designated position, so that the film splicing table is in front of or close to the front side of the mother roll. In this way, it is convenient for the operator to stand in front of the mother roll to perform the film splicing operation, effectively reducing the impact of the mother roll blocking the film splicing operation and facilitating the operator's film splicing operation. After the film splicing operation is completed, the translation mechanism drives the sliding seat to move the film splicing table backward to the designated position, without affecting the mother roll to continue unwinding, while saving space and improving the structural compactness.

[0007] Preferably, the film splicing device includes a film splicing guide rail mounted on the frame, extending along the front-rear direction of the slitting machine. One end of the film splicing guide rail, near the front of the slitting machine, slopes downwards. The sliding seat slides along the film splicing guide rail, and the film splicing platform is positioned above the master roll on the unwinding rack. Thus, when defective film material is observed being output, the translation mechanism drives the sliding seat to move the film splicing platform forward to a designated position. This not only positions the film splicing platform in front of or near the front of the master roll but also lowers the platform's height, making film splicing operations more convenient for the operator.

[0008] Preferably, the tilt angle of the film-attachment guide rail is 15-45 degrees. If the tilt angle of the film-attachment guide rail is too small, the height reduction of the film-attachment platform after the translation mechanism drives the sliding seat to move the film-attachment platform forward to the designated position will be minimal, which is not conducive to the operator's film-attachment operation. If the tilt angle of the film-attachment guide rail is too large, the film material may fall off the film-attachment platform during the film-attachment operation, which is also not conducive to the operator's film-attachment operation. Therefore, the solution sets the tilt angle of the film-attachment guide rail to 15-45 degrees. In this way, after the translation mechanism drives the sliding seat to move the film-attachment platform forward to the designated position, the height can be effectively reduced, thus facilitating the operator's film-attachment operation. At the same time, it can avoid the problem of film material falling off the film-attachment platform during the film-attachment operation caused by the excessive tilt angle of the film-attachment platform.

[0009] Preferably, one film-attaching guide roller, the film-attaching platform, and the other film-attaching guide roller are distributed sequentially along the sliding direction of the sliding seat. The film material of the master roll on the unwinding frame passes around each film-attaching guide roller in sequence. The platform of the film-attaching platform is set facing upwards, and the platform of the film-attaching platform is located below and close to the film material.

[0010] Preferably, the film splicing device further includes a fixed limiting member and a movable limiting member, wherein the fixed limiting member is fixedly mounted on the frame, and the movable limiting member is mounted on the sliding seat; when the movable limiting member abuts against the fixed limiting member, the sliding seat moves to its foremost position. In this way, the position in which the sliding seat moves forward can be limited by the cooperation of the fixed limiting member and the movable limiting member.

[0011] Preferably, the system also includes a base plate and a frame movement actuator. The base plate is equipped with a translation guide rail, which is parallel to the horizontal rotating shaft. The axis of the mother roll on the unwinding frame is also parallel to the horizontal rotating shaft. The frame slides along the translation guide rail, and the frame movement actuator drives the frame to move. Currently, mother rolls are generally transported to a designated position in front of the slitting machine by a trolley or by rolling them directly on the bottom surface. Therefore, the positional accuracy of the mother roll in the axial direction is not high when it reaches the designated position in front of the slitting machine, and adjusting its axial position is inconvenient. To address this, this solution slides the frame on the translation guide rail, and the frame can be driven to move by the frame movement actuator. Thus, after the mother roll is transported to the designated position in front of the slitting machine, if its axial position is unsuitable, the frame movement actuator can drive the frame to move, and the unwinding frame can be moved to utilize the mother roll's position, facilitating the unwinding operation.

[0012] Preferably, the tilting frame is equipped with an unwinding guide rail, which is parallel to the horizontal rotating shaft. The unwinding frame includes: Two unwinding arms move along the unwinding guide rail. Each unwinding arm is equipped with a rotating chuck. The rotating chucks on the two unwinding arms are coaxially distributed, and the core of the mother roll is installed between the rotating chucks of the two unwinding arms. The unwinding drive mechanism is located on the unwinding arm and drives the rotating chuck to rotate. The unwinding arm drive actuator moves the two unwinding arms closer together or further apart. The timing of the tilting frame's operation is as follows: When the master roll is transported to the designated position in front of the slitting machine, the flipping mechanism drives the flipping frame to rotate around the horizontal axis, causing the unwinding frame to rotate downwards to the designated position. Then, the unwinding arm drive actuator drives the two unwinding arms to move closer together, causing the rotating clamps on the two unwinding arms to clamp the two ends of the master roll (the rotating clamps on the two unwinding arms are inserted into the holes at both ends of the master roll core). Next, the flipping mechanism drives the flipping frame to rotate around the horizontal axis, causing the unwinding frame to rotate the master roll upwards to the designated position, thus achieving automatic winding. This facilitates the winding operation of the master roll and reduces the manual handling steps during the winding process. After the film material on the master roll is completely released, the flipping mechanism drives the flipping frame to rotate around the horizontal axis, causing the unwinding frame to rotate the master roll downwards to the designated position, thus achieving automatic unwinding. Its operation is convenient, enabling automatic winding and unwinding, thereby reducing labor intensity and improving production efficiency.

[0013] Preferably, the unwinding device further includes a flipping upper limit stop and a flipping lower limit stop, which are fixedly mounted on the frame. The flipping frame is located between the flipping upper limit stop and the flipping lower limit stop. When the flipping frame abuts against the flipping upper limit stop, the master roll on the unwinding frame descends to the lowest position.

[0014] Preferably, the tilting mechanism is an electric cylinder or a linear module. This allows for precise control of the tilting frame's rotation around a horizontal axis, enabling the unwinding frame to rotate upwards or downwards to a designated position. Furthermore, compared to hydraulic cylinder drives, this avoids the risks of slow hydraulic response and oil leakage leading to contamination.

[0015] Preferably, the translation mechanism is a pneumatic cylinder, an electric cylinder, or a linear module. In this way, the sliding seat can be driven by the pneumatic cylinder, electric cylinder, or linear module, thereby moving the film-attaching stage forward to the designated position.

[0016] The beneficial effects of this utility model are: Firstly, after the master roll is transported to the designated position in front of the slitting machine, the flipping mechanism drives the flipping frame to rotate around the horizontal axis, causing the unwinding frame to rotate downwards to the designated position, so that the master roll can be installed on the unwinding frame without moving or handling. Then, the master roll is installed on the unwinding frame. Next, the flipping mechanism drives the flipping frame to rotate around the horizontal axis, causing the unwinding frame to drive the master roll upwards to the designated position to achieve automatic winding, thereby facilitating the winding operation of the master roll and reducing the manual handling steps of the master roll during the winding operation.

[0017] Secondly, since the translation mechanism of the film splicing device can drive the sliding seat and the film splicing table to move along the front and back direction of the slitting machine, when a defective film material is observed to be output, the translation mechanism drives the sliding seat to move the film splicing table forward to the designated position, so that the film splicing table is in front of or close to the front side of the mother roll. In this way, it is convenient for the operator to stand in front of the mother roll to perform the film splicing operation, effectively reducing the impact of the mother roll blocking the film splicing operation and facilitating the operator's film splicing operation. After the film splicing operation is completed, the translation mechanism drives the sliding seat to move the film splicing table backward to the designated position, without affecting the mother roll to continue unwinding, while saving space and improving the structural compactness.

[0021] Specific Implementation Example 1, such as Figure 1 , Figure 2 As shown, a slitting machine unwinding frame structure that facilitates unwinding and film splicing includes a frame 1, an unwinding device 2, and a film splicing device 3.

[0022] The unwinding device 2 includes a tilting frame 2.1, an unwinding rack 2.2, and a tilting mechanism 2.3. The tilting frame 2.1 is rotatably mounted on the lower part of the frame 1 via a horizontal rotating shaft 2.4. The unwinding rack 2.2 is used to hold the master roll 4 and is mounted on the tilting frame 2.1. The tilting mechanism 2.3 drives the tilting frame 2.1 to rotate around the horizontal rotating shaft 2.4, thereby raising or lowering the master roll 4 on the unwinding rack 2.2. The axis of the master roll 4 on the unwinding rack 2.2 is parallel to the horizontal rotating shaft 2.4.

[0023] The film splicing device 3 includes a sliding seat 3.1, two film splicing guide rollers 3.2, a film splicing platform 3.3, and a translation mechanism 3.4. The sliding seat 3.1 is slidably mounted on the frame 1 along the front-to-back direction of the slitting machine. The sliding seat 3.1 is located at the front of the slitting machine. The two film splicing guide rollers 3.2 are rotatably mounted on the sliding seat 3.1. The film splicing guide rollers 3.2 are parallel to the horizontal rotating shaft 2.4.

[0024] The film splicing platform 3.3 is mounted on the sliding seat 3.1 and is located between the two film splicing guide rollers 3.2. The film material of the master roll 4 on the unwinding frame 2.2 passes sequentially around the two film splicing guide rollers 3.2. The platform surface of the film splicing platform 3.3 is positioned upwards and is located below and close to the film material. The translation mechanism 3.4 drives the sliding seat 3.1 to move.

[0025] The specific use of the unwinding frame structure of the slitting machine in this embodiment, which facilitates film loading and splicing, is as follows. After the master roll 4 is transported to the designated position in front of the slitting machine, the flipping mechanism 2.3 drives the flipping frame 2.1 to rotate around the horizontal rotating shaft 2.4, causing the unwinding frame 2.2 to rotate downwards to the designated position, so that the master roll 4 can be installed on the unwinding frame 2.2 without moving or handling. Then, the master roll 4 is installed on the unwinding frame 2.2. Next, the flipping mechanism 2.3 drives the flipping frame 2.1 to rotate around the horizontal rotating shaft 2.4, causing the unwinding frame 2.2 to drive the master roll 4 upwards to the designated position to achieve automatic winding, thereby facilitating the winding operation of the master roll 4 and reducing the manual handling steps of the master roll 4 during the winding operation.

[0026] On the other hand, during the unwinding process of master roll 4, if defective film material is observed being output, the translation mechanism 3.4 drives the sliding seat 3.1 to move the splicing table 3.3 forward to a designated position. Then, when the defective film material is conveyed to the splicing table 3.3, the unwinding of master roll 4 is paused. Next, the defective portion of the film material is completely cut off on the splicing table 3.3, and then the film material is spliced. Then, the translation mechanism 3.4 drives the sliding seat 3.1 to move the splicing table 3.3 backward to a designated position, and master roll 4 continues to unwind. In this way, defective film material in master roll 4 can be removed. Meanwhile, since the translation mechanism 3.4 of the film splicing device 3 can drive the sliding seat 3.1 and the film splicing platform 3.3 to move along the front and back direction of the slitting machine, when a defective film material is observed to be output, the translation mechanism 3.4 drives the sliding seat 3.1 to move the film splicing platform 3.3 forward to the designated position, so that the film splicing platform 3.3 is located in front of or near the front side of the mother roll 4. In this way, it is convenient for the operator to stand in front of the mother roll 4 to perform the film splicing operation, effectively reducing the impact of the mother roll 4 blocking the film splicing operation, and facilitating the operator's film splicing operation. After the film splicing operation is completed, the translation mechanism 3.4 drives the sliding seat 3.1 to move the film splicing platform 3.3 backward to the designated position, without affecting the mother roll 4 to continue unwinding, while saving space and improving the structural compactness.

[0027] Specific embodiment two, such as Figure 1 , Figure 2 As shown, a slitting machine unwinding frame structure that facilitates unwinding and film splicing includes a frame 1, an unwinding device 2, and a film splicing device 3.

[0028] The unwinding device 2 includes a tilting frame 2.1, an unwinding frame 2.2, and a tilting mechanism 2.3. The tilting frame 2.1 is rotatably mounted on the lower part of the frame 1 via a horizontal pivot 2.4. The unwinding frame 2.2 is used to hold the master roll 4 and is mounted on the tilting frame 2.1. The tilting mechanism 2.3 drives the tilting frame 2.1 to rotate around the horizontal pivot 2.4, causing the master roll 4 on the unwinding frame 2.2 to rise or fall. The axis of the master roll 4 on the unwinding frame 2.2 is parallel to the horizontal pivot 2.4. Specifically, The tilting mechanism 2.3 is either an electric cylinder or a linear module. This allows for precise control of the tilting frame 2.1's rotation around the horizontal axis 2.4, enabling the unwinding frame 2.2 to rotate upwards or downwards to a specified position. Furthermore, compared to hydraulic cylinder drives, this avoids the risks of slow hydraulic response and oil leakage leading to contamination.

[0029] The tilting frame 2.1 is equipped with an unwinding guide rail 2.7. The unwinding guide rail 2.7 is parallel to the horizontal rotating shaft 2.4. The unwinding frame 2.2 includes two unwinding arms 2.21, an unwinding drive mechanism, and an unwinding arm drive actuator. The two unwinding arms 2.21 move along the unwinding guide rail 2.7. Rotating chucks are rotatably mounted on both unwinding arms 2.21. The rotating chucks on the two unwinding arms 2.21 are coaxially distributed. The core of the mother roll 4 is installed between the rotating chucks of the two unwinding arms 2.21, and the rotating chucks can extend into both ends of the core of the mother roll 4 (the core is a cylindrical structure). The unwinding arm drive actuator is located on the tilting frame 2.1 and drives the two unwinding arms 2.21 to move closer together or separate. The unwinding arm drive actuator is a pneumatic cylinder, an electric cylinder, or a linear module.

[0030] The unwinding drive mechanism is located on the unwinding arm 2.21 and drives the rotating chuck to rotate.

[0031] In one example, one of the two unwinding arms 2.21 is equipped with an unwinding drive mechanism, which includes a chuck drive motor. The unwinding drive mechanism drives the corresponding rotating chuck to rotate.

[0032] In another example, both unwinding arms 2.21 are equipped with unwinding drive mechanisms, each including a chuck drive motor. The unwinding drive mechanism drives the corresponding rotating chuck to rotate.

[0033] The film splicing device 3 includes a sliding seat 3.1, two film splicing guide rollers 3.2, a film splicing platform 3.3, and a translation mechanism 3.4. The sliding seat 3.1 is slidably mounted on the frame 1 along the front-to-back direction of the slitting machine. The sliding seat 3.1 is located at the front of the slitting machine. The two film splicing guide rollers 3.2 are rotatably mounted on the sliding seat 3.1. The film splicing guide rollers 3.2 are parallel to the horizontal rotating shaft 2.4.

[0034] A film-attaching platform 3.3 is mounted on a sliding seat 3.1. The film-attaching platform 3.3 is located between two film-attaching guide rollers 3.2. One film-attaching guide roller 3.2, the film-attaching platform 3.3, and the other film-attaching guide roller 3.2 are sequentially distributed along the sliding direction of the sliding seat 3.1. The film material of the master roll 4 on the unwinding frame 2.2 sequentially passes over the two film-attaching guide rollers 3.2. The platform surface of the film-attaching platform 3.3 is positioned upwards, and is located below and close to the film material. A translation mechanism 3.4 drives the sliding seat 3.1 to move.

[0035] The translation mechanism 3.4 is a pneumatic cylinder, an electric cylinder, or a linear module. In this way, the sliding seat 3.1 can be driven by the pneumatic cylinder, electric cylinder, or linear module, thereby moving the film-attaching stage 3.3 forward to the designated position.

[0036] The specific use of the unwinding frame structure of the slitting machine in this embodiment, which facilitates film loading and splicing, is as follows. After the master roll 4 is transported to the designated position in front of the slitting machine, the flipping mechanism 2.3 drives the flipping frame 2.1 to rotate around the horizontal axis 2.4, causing the unwinding frame 2.2 to rotate downwards to a designated position, allowing the master roll 4 to be installed onto the unwinding frame 2.2 without moving or handling. Next, the unwinding arm drive actuator drives the two unwinding arms 2.21 to move closer together, causing the rotating chucks on the two unwinding arms 2.21 to insert into the two ends of the core at the center of the master roll 4, clamping the two ends of the core, thereby installing the master roll 4 between the rotating chucks on the two unwinding arms 2.21. Then, the flipping mechanism 2.3 drives the flipping frame 2.1 to rotate around the horizontal axis 2.4, causing the unwinding frame 2.2 to rotate the master roll 4 upwards to a designated position, thus achieving automatic winding, facilitating the winding operation of the master roll 4, and reducing the manual handling steps of the master roll 4 during the winding process.

[0037] When the master roll 4 is unwound, the unwinding drive mechanism drives the rotating chuck to rotate, which in turn drives the master roll 4 between the rotating chucks on the two unwinding arms 2.21 to rotate, thereby realizing the unwinding of the master roll 4.

[0038] After the film material on the master roll 4 is completely released, the flipping mechanism 2.3 drives the flipping frame 2.1 to rotate around the horizontal rotating shaft 2.4, so that the unwinding frame 2.2 drives the master roll 4 to rotate downward to a specified position, thereby realizing automatic unwinding; it is easy to operate and can realize automatic unwinding, thereby reducing labor intensity and improving production efficiency.

[0039] On the other hand, during the unwinding process of master roll 4, if defective film material is observed being output, the translation mechanism 3.4 drives the sliding seat 3.1 to move the splicing table 3.3 forward to a designated position. Then, when the defective film material is conveyed to the splicing table 3.3, the unwinding of master roll 4 is paused. Next, the defective portion of the film material is completely cut off on the splicing table 3.3, and then the film material is spliced. Then, the translation mechanism 3.4 drives the sliding seat 3.1 to move the splicing table 3.3 backward to a designated position, and master roll 4 continues to unwind. In this way, defective film material in master roll 4 can be removed. Meanwhile, since the translation mechanism 3.4 of the film splicing device 3 can drive the sliding seat 3.1 and the film splicing platform 3.3 to move along the front and back direction of the slitting machine, when a defective film material is observed to be output, the translation mechanism 3.4 drives the sliding seat 3.1 to move the film splicing platform 3.3 forward to the designated position, so that the film splicing platform 3.3 is located in front of or near the front side of the mother roll 4. In this way, it is convenient for the operator to stand in front of the mother roll 4 to perform the film splicing operation, effectively reducing the impact of the mother roll 4 blocking the film splicing operation, and facilitating the operator's film splicing operation. After the film splicing operation is completed, the translation mechanism 3.4 drives the sliding seat 3.1 to move the film splicing platform 3.3 backward to the designated position, without affecting the mother roll 4 to continue unwinding, while saving space and improving the structural compactness.

[0040] Furthermore, such as Figure 1 , Figure 2 As shown, a slitting machine unwinding frame structure that facilitates film loading and splicing also includes a base plate 5 and a frame movement actuator 6. A translation guide rail 5.1 is provided on the base plate 5. The translation guide rail 5.1 is parallel to the horizontal rotating shaft 2.4. The frame 1 slides along the translation guide rail 5.1, and the frame movement actuator 6 drives the frame 1 to move. The frame movement actuator 6 is an electric cylinder or a linear module. Currently, the mother roll 4 is generally transported to the designated position in front of the slitting machine by a trolley or by rolling it directly on the bottom surface. As a result, the positional accuracy of the mother roll 4 in the axial direction is not high when it is transported to the designated position in front of the slitting machine, and the position adjustment of the mother roll 4 in the axial direction is inconvenient. Therefore, in this embodiment, the frame 1 is slidably mounted on the translation guide rail 5.1, and the frame 1 can be driven to move by the frame moving actuator 6. In this way, after the mother roll 4 is transported to the designated position in front of the slitting machine, if the position of the mother roll 4 in the axial direction is not suitable, the frame 1 can be driven to move by the frame moving actuator 6, and the position of the mother roll 4 can be used by moving the unwinding frame 2.2, which facilitates the winding operation of the mother roll 4.

[0041] Furthermore, such as Figure 1As shown, the unwinding device 2 also includes a flipping upper limit stop 2.6 and a flipping lower limit stop 2.5. The flipping upper limit stop 2.6 and the flipping lower limit stop 2.5 are fixedly mounted on the frame 1. The flipping frame 2.1 is located between the flipping upper limit stop 2.6 and the flipping lower limit stop 2.5. When the flipping frame 2.1 abuts against the flipping upper limit stop 2.6, the mother roll 4 on the unwinding frame 2.2 descends to the lowest position.

[0042] Furthermore, such as Figure 1 As shown, the film splicing device 3 includes a film splicing guide rail 3.7 mounted on the frame 1. The film splicing guide rail 3.7 extends along the front-rear direction of the slitting machine. The end of the film splicing guide rail 3.7 near the front of the slitting machine slopes downward. The sliding seat 3.1 slides along the film splicing guide rail 3.7, and the film splicing platform 3.3 is located above the master roll 4 on the unwinding frame 2.2. Thus, when a defective film material is observed being output, the translation mechanism 3.4 drives the sliding seat 3.1 to move the film splicing platform 3.3 forward to a designated position. This not only positions the film splicing platform 3.3 in front of or near the front side of the master roll 4, but also lowers the height of the film splicing platform 3.3, making the film splicing operation more convenient for the operator.

[0043] Furthermore, such as Figure 1 As shown, the tilt angle of the film-attachment guide rail 3.7 is 15-45 degrees. For example, the tilt angle of the film-attachment guide rail 3.7 is 30 degrees. If the tilt angle of the film-attachment guide rail 3.7 is too small, after the translation mechanism 3.4 drives the sliding seat 3.1 to move the film-attachment platform 3.3 forward to the designated position, the height reduction of the film-attachment platform 3.3 is minimal, which is not conducive to the operator's film-attachment operation. If the tilt angle of the film-attachment guide rail 3.7 is too large, the film material may fall off the film-attachment platform 3.3 during the film-attachment operation, which is also not conducive to the operator's film-attachment operation. Therefore, the solution sets the tilt angle of the film-attachment guide rail 3.7 to 15-45 degrees. In this way, after the translation mechanism 3.4 drives the sliding seat 3.1 to move the film-attachment platform 3.3 forward to the designated position, the height can be effectively reduced, thus facilitating the operator's film-attachment operation. It also avoids the problem of the film material falling off the film-attachment platform 3.3 during the film-attachment operation if the tilt angle of the film-attachment platform 3.3 is too large.

[0044] Furthermore, such as Figure 1 As shown, the film-attaching device 3 also includes a fixed limiting member 3.5 and a movable limiting member 3.6. The fixed limiting member 3.5 is fixedly mounted on the frame 1, and the movable limiting member 3.6 is mounted on the sliding seat 3.1. When the movable limiting member 3.6 abuts against the fixed limiting member 3.5, the sliding seat 3.1 moves to its foremost position. In this way, the position of the sliding seat 3.1 moving forward can be limited by the cooperation of the fixed limiting member 3.5 and the movable limiting member 3.6.

[0045] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
