[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] In this technical solution, a door lock device for a wrapping machine includes two fixed frames 1, a fixed plate 2 installed between the two fixed frames 1, and a flip-over protective structure installed on the upper end of the fixed plate 2 and the two fixed frames 1. The flip-over protective structure includes two hinge seats 3, an operating shaft 4, two connecting rods 5, two flip-over frames 6, a top plate 7, a protective component, a drive component, and a positioning component.

[0026] Two hinge seats 3 are fixedly installed on one side of the upper end of two fixed frames 1 respectively. The two ends of the operating shaft 4 are movably embedded in the two hinge seats 3 respectively. One end of the two connecting rods 5 is fixedly fitted onto the two ends of the operating shaft 4 respectively. One end of the two flip frames 6 is connected to the other end of the two connecting rods 5 respectively. The top plate 7 is fixedly installed on the upper end between the two flip frames 6. The protective component is installed on the front end between the two flip frames 6. One end of the drive component is fixedly installed on the upper end of the fixed plate 2, and the other end is fixedly fitted onto the center of the upper end of the operating shaft 4. One end of the positioning component is fixedly installed on one side of the upper end of the fixed plate 2, and the other end is fixedly fitted onto one side of the upper end of the operating shaft 4.

[0027] In this technical solution, when protecting the feeding position of the wrapping machine, the workers first fix two fixed frames 1 to the upper end of the wrapping machine by welding. Then, the device is connected to the designated control system. When it is necessary to protect the feeding position of the wrapping machine, the set drive component works to drive the operating shaft 4 to rotate within the two hinge seats 3. During the rotation of the operating shaft 4, the two connecting rods 5 follow the operating shaft 4 to rotate within the two hinge seats 3. At the same time, the two flipping frames 6 located at one end of the two connecting rods 5 also rotate, flipping the top plate 7 and the protective component at the upper end of the two flipping frames 6 to the specified angle to wrap the feeding position of the wrapping machine. Then, the positioning component works to limit the rotation of the operating shaft 4 to ensure the stability of the protection of the feeding position of the wrapping machine. After the material is packaged, the material can be replaced by opening the protective component, or the positioning component can be released from the limit of the operating shaft 4, and the flipping frame 6 can be reset by the drive component to replace the material.

[0028] In some technical solutions, reference Figure 1The protective components include a protective frame 8, an electric push rod 9, an operating groove 10, two guide grooves 11, a moving block 12, a snap-fit ​​block 13, a connecting shaft 14, and an opening and closing plate 15.

[0029] The protective frame 8 is fixedly installed at the front end between the two flipping frames 6. The electric push rod 9 is fixedly installed on one side of the upper end of the top plate 7. The operating groove 10 is opened at the center of the upper end of the protective frame 8. Two guide grooves 11 are respectively opened on both sides of the operating groove 10. The moving block 12 is movably embedded in the operating groove 10, and its two ends are respectively movably embedded in the two guide grooves 11. The snap-fit ​​block 13 is fixedly installed at the lower end of the moving block 12. The two ends of the connecting shaft 14 are respectively movably embedded in the upper and lower walls of one side of the protective frame 8 through bearings. One end of the opening and closing plate 15 is fixedly connected to one end of the connecting shaft 14.

[0030] In this technical solution, when the material is small, the electric push rod 9 at the top of the drive plate 7 drives the moving block 12 to move upward within the operating groove 10 and the two guide grooves 11, causing the locking block 13 to separate from the upper end of the opening and closing plate 15. The opening and closing plate 15 can then be unfolded via the connecting shaft 14, and the material can be replaced through the protective frame 8. The operating groove 10 and guide grooves 11 provide longitudinal guidance for the moving block 12, ensuring the stability of the lifting of the locking block 13 and thus ensuring the docking and limiting effect between the locking block 13 and the opening and closing plate 15.

[0031] In some technical solutions, reference Figure 1 The drive assembly includes a motor 16, a first gear 17, and a second gear 18;

[0032] The motor 16 is fixedly installed on one side of the upper end of the fixed plate 2, the first gear 17 is fixedly installed at the drive end of the motor 16, and the second gear 18 is fixedly installed on the upper end of the operating shaft 4 and meshes with the first gear 17.

[0033] In this technical solution, when the flipping frame 6 is flipped, the motor 16 at the top of the drive plate 7 works, and the second gear 18 and the operating shaft 4 are driven by the meshing action of the first gear 17 and the second gear 18, and the flipping frame 6 is flipped by the operating shaft 4.

[0034] In some technical solutions, reference Figure 1 The positioning assembly includes a positioning frame 19, two positioning holes 20, a positioning cylinder 21, and a positioning rod 22.

[0035] The positioning frame 19 is fixedly mounted on one side of the upper end of the operating shaft 4. Two positioning holes 20 are respectively opened on both sides of the positioning frame 19. The positioning cylinder 21 is fixedly installed on one side of the upper end of the fixing plate 2. One end of the positioning rod 22 is fixedly installed on the telescopic end of the positioning cylinder 21, and the other end is movably embedded in one of the positioning holes 20.

[0036] In this technical solution, when limiting the flipping angle of the flipping frame 6, the positioning cylinder 21 at the upper end of the top plate 7 is driven to work. The positioning cylinder 21 pushes the positioning rod 22 to one side until one end of the positioning rod 22 is embedded in one of the positioning holes 20 in the positioning frame 19. Since the positioning frame 19 is L-shaped, the two positioning holes 20 are located at both ends of the positioning frame 19. Therefore, when the flipping frame 6 is in the closed state, one positioning hole 20 corresponds to the positioning rod 22, and when the flipping frame 6 is in the unfolded state, the other positioning hole 20 corresponds to the positioning rod 22.

[0037] In some technical solutions, reference Figure 1 The fixed frame 1 is an "L"-shaped positioning frame 19, the flipping frame 6 is an "L"-shaped positioning frame 19, and the connecting rod 5 is an "L"-shaped connecting rod 5.
