Description

Technical Field

[0001] This utility model relates to the field of blister tray processing technology, and in particular to a cutting device for blister tray processing. Background Technology

[0002] The need for cutting blister trays is an inevitable step determined by both the production process and practical application requirements. In the blister forming process, plastic sheets are heated and softened, and then vacuum-adsorbed or pressure-extended through a mold to form a continuous sheet-like semi-finished product with a specific structure. At this time, the multiple blister trays on the sheet have not yet been separated, and they must be divided into independent individuals through the cutting process in order to meet the requirements of subsequent packaging, storage and transportation.

[0003] Currently, the main problems with blister tray cutting equipment are as follows: First, the transmission system of traditional cutting devices mostly uses belt or chain transmission, which has problems such as low transmission accuracy and easy slippage, resulting in large cutting position errors and making it difficult to meet the processing requirements of precision blister trays; Second, the material positioning mechanism of existing equipment lacks flexibility, and the fixed-spacing guide structure cannot be adapted to blister trays of different specifications. When facing the production needs of small batches and multiple varieties, tooling fixtures need to be changed frequently, which seriously restricts production efficiency. Utility Model Content

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Reference Figures 1 to 4 As shown, this utility model provides a technical solution: a cutting device for processing blister trays, including a transmission frame 1, a fixed frame 2 fixedly connected to the surface of the transmission frame 1, a servo motor 3 installed on the top of the fixed frame 2, the output end of the servo motor 3 passing through the surface of the fixed frame 2 and fixedly connected to an upper ratchet disc 4, the lower end of the upper ratchet disc 4 being engaged with a lower ratchet disc 5, and the lower end of the lower ratchet disc 5 being fixedly connected to a cutting tool 8. The upper ratchet disc is driven to rotate by the output end of the servo motor 3. When the upper ratchet disc rotates, it intermittently pushes the lower ratchet disc downward through multiple inclined surfaces on its surface, thereby intermittently cutting the blister trays on the surface of the transmission belt and improving work efficiency.

[0026] Reference Figure 1 and Figure 2As shown in this embodiment: a support plate 6 is fixedly connected to the surface of the fixed frame 2, and a return spring 7 is fixedly connected to the surface of the support plate 6. The upper end of the return spring 7 is fixedly connected to the lower surface of the lower pawl disk 5. By setting the return spring 7, when the lower pawl disk 5 moves downward, the return spring 7 pushes the lower pawl disk 5 upward by restoring its elastic deformation, so that the lower pawl disk 5 and the upper pawl disk 4 mesh with each other, thereby enabling continuous cutting operations. Side plates 9 are fixedly connected to both sides of the lower pawl disk 5, and guide rods 10 are slidably connected to the surface of the side plates 9. The lower end of the guide rods 10 is fixedly connected to the surface of the support plate 6. By setting the side plates 9 and the guide rods 10, when the upper pawl disk 4 rotates, it will not drive the lower pawl disk 5 to rotate. At the same time, when the lower pawl disk 5 moves downward, the guide rods 10 can limit the lower pawl disk 5, so that the lower pawl disk 5 will not deviate when it moves.

[0027] Reference Figure 3 and Figure 4 As shown, specifically, a guide frame 11 is provided on one side of the fixed frame 2. The lower end of the guide frame 11 is fixedly connected to the surface of the transmission frame 1, and an adjustment groove 12 is provided on the surface of the guide frame 11. A bidirectional screw 13 is rotatably connected to the inner wall of the adjustment groove 12. Two sliding blocks 14 are threadedly connected to the surface of the bidirectional screw 13. A vertical plate 15 is fixedly connected to the lower end of the two sliding blocks 14. A guide frame 16 is fixedly connected to the lower end of the vertical plate 15. An adjustment frame 17 is rotatably connected to one end of the guide frame 16. A fixing bolt 19 is provided at the connection between the adjustment frame 17 and the guide frame 16. Multiple side wheels 18 are rotatably connected to the inner walls of the guide frame 16 and the adjustment frame 17. The bidirectional screw 13... A turntable 21 is fixedly connected to the side wall of the guide frame 11 at one end. A sliding rod 20 is fixedly connected to the surface of the guide frame 11. The sliding rod 20 is slidably connected to the surface of the vertical plate 15. By rotating the turntable 21, the sliding blocks 14 on both sides can be driven to move synchronously in opposite directions by the bidirectional screw 13, thereby adjusting the lateral spacing of the vertical plate 15 and the guide frame 16. This can adapt to the conveying and positioning requirements of blister tray materials of different specifications. The side wheels 18 set on the inner wall of the guide frame 16 and the adjustment frame 17 can rotate freely to reduce the material conveying resistance. The fixing bolts 19 set on the surface of the adjustment frame 17 can adjust the opening angle of the adjustment frame 17 to adapt to the guiding requirements of irregular materials and enhance the versatility of the equipment.

[0028] Working principle: When the equipment is started, the servo motor 3 drives the upper ratchet disk 4 to rotate. Multiple inclined surfaces on the surface of the upper ratchet disk 4 cooperate with the lower ratchet disk 5. During the rotation, the lower ratchet disk 5 is intermittently pushed downward. At this time, the cutting blade 8 connected to the lower end of the lower ratchet disk 5 moves downward synchronously, performing a cutting operation on the blister tray conveyed at a constant speed on the surface of the transmission frame 1, avoiding ineffective empty cutting and greatly improving cutting efficiency. After the cutting action is completed, the return spring 7 fixed to the support plate 6 undergoes elastic deformation when the lower ratchet disk 5 moves downward. When the external force disappears, the spring pushes the lower ratchet disk 5 upward by its own restoring force, so that it re-engages with the upper ratchet disk 4. At the same time, the side plates 9 on both sides of the lower ratchet disk 5 and the guide rod 10 form a sliding limit structure to ensure that the lower ratchet disk 5 can only move in the vertical direction, preventing it from moving with the upper ratchet disk. The rotation of disc 4 ensures the straightness of the movement trajectory of the cutting blade 8, effectively preventing cutting deviation and guaranteeing high precision and consistency of cutting dimensions. At the same time, the operator can rotate the turntable 21 on the guide frame 11 to drive the bidirectional screw 13 in the adjustment groove 12 to rotate. The bidirectional screw 13 drives the sliding blocks 14 on both sides to move synchronously in opposite directions, thereby driving the vertical plate 15 and the guide frame 16 to adjust the horizontal spacing to adapt to the width of different specifications of blister trays. The side wheels 18 set on the inner wall of the guide frame 16 and the adjustment frame 17 can significantly reduce the conveying resistance and avoid scratches on the material surface through rolling contact. The fixing bolts 19 on the surface of the adjustment frame 17 can flexibly adjust the opening angle of the adjustment frame 17 to achieve stable guiding and conveying of plastic trays of different specifications, enhancing the equipment's adaptability to the processing of diverse products.
