Description

Technical Field

[0001] This utility model relates to the field of blister tray processing technology, specifically a blister tray waste cutting device. Background Technology

[0002] Blister trays, also known as plastic trays or blister trays, are disc-shaped containers formed from rigid plastic sheets through heating and vacuum forming processes in a mold. The production and processing of blister trays is a relatively complex process, encompassing multiple stages from raw material selection to final product packaging. Among these stages, the blister trays need to be cut. A cutting machine is used to cut the formed blister trays from the sheet material, ensuring the dimensional accuracy and edge neatness of the trays according to the design dimensions and shape requirements. A blister tray cutting device is a piece of equipment used to precisely cut the blister-formed trays to achieve the specified dimensions and shapes.

[0003] In the early production of blister trays, manual transfer was often used. Workers would manually move the blister trays from one workstation to another, such as from the production line to the waste cutting station, and then move the cut trays to the next process. This method was not only labor-intensive and inefficient, but also prone to inaccurate tray positioning due to human factors, affecting the cutting quality. It was also difficult to meet the needs of large-scale production. Furthermore, traditional cutting equipment often used relatively simple mechanical structures, such as manual cutting with fixed blades or simple mechanical transmission cutting devices. During the cutting process, it was difficult to accurately control the movement trajectory and cutting force of the blades, which could easily lead to large deviations in the cutting dimensions and fail to meet the production requirements of high-precision blister trays. Utility Model Content

[0004] To address the issues of manual pallet handling and controlling cutting force, the purpose of this invention is to provide a cutting device for blister tray waste.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a blister tray waste cutting device, including a cutting table, a cutting mechanism fixedly installed on one side of the upper surface of the cutting table, a bracket fixedly installed on one side of the cutting table, a horizontal plate fixedly installed on the upper end of the bracket, a lead screw rotatably connected to one side of the horizontal plate, a first motor fixedly installed at the end of the horizontal plate, the output end of the first motor fixedly connected to the lead screw, a movable frame threaded onto the outer surface of the lead screw, a clamping device slidably connected to one side of the movable frame, the clamping device including an upper support plate and a slide rail, clamping arms symmetrically slidably provided on the lower surface of the upper support plate and rotatably connected to a rotating plate, inclined connecting rods symmetrically rotatably connected to the outer surface of the rotating plate, one end of each of the two inclined connecting rods being rotatably connected to two clamping arms respectively, a second cylinder fixedly installed on the lower surface of one clamping arm, the output end of the second cylinder being fixedly connected to the other clamping arm, and a clamping plate fixedly connected to the lower end of the clamping arm.

[0006] Preferably, the cutting mechanism includes a U-shaped plate, the lower surface of which is fixedly connected to a cutting table, a rotating rod rotatably connected to the upper end of the U-shaped plate, a transmission box fixedly installed on the upper surface of the U-shaped plate, the rotating rod passing through the transmission box, a second motor fixedly installed on the upper surface of the transmission box, the output end of the second motor passing through the transmission box and fixedly sleeved with a second bevel gear, a first bevel gear fixedly sleeved on the outer surface of the rotating rod, the outer surface of the first bevel gear meshing with the outer surface of the second bevel gear, turntables fixedly connected to both ends of the rotating rod, a connecting rod rotatably connected to the outer surface of the turntables, and a cutting blade fixedly connected to the lower end of the connecting rod.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This utility model, through the combined use of a clamping device that can move horizontally and vertically and a cutting mechanism, allows the clamping device to move flexibly in three-dimensional space by means of horizontal and vertical movement. The screw drive and cylinder precision control ensure the positioning accuracy of the clamping device during horizontal and vertical movement, and can accurately place the tray in the appropriate position on the cutting table for cutting.

[0014] 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.

[0015] Example: Figure 1-3As shown, this utility model provides a cutting device for blister tray waste, including a cutting table 18. A cutting mechanism 19 is fixedly installed on one side of the upper surface of the cutting table 18. A bracket 11 is fixedly installed on one side of the cutting table 18. A horizontal plate 10 is fixedly installed on the upper end of the bracket 11. A first guide rod 12 is fixedly installed on the upper surface of the horizontal plate 10. The outer surface of the first guide rod 12 is slidably sleeved with one side of the movable frame 14. The first guide rod 12 guides the movable frame 14. During the horizontal movement of the movable frame 14 driven by the lead screw 13, the first guide rod 12 ensures that the movable frame 14 moves along a straight line, enhancing the stability and accuracy of the movement of the movable frame 14. The lead screw 13 is rotatably connected to one side of the horizontal plate 10, and a first motor is fixedly installed at the end of the horizontal plate 10. 40. The output end of the first motor 40 is fixedly connected to the lead screw 13. The outer surface of the lead screw 13 is threaded with a movable frame 14. The upper surface of the movable frame 14 is fixedly mounted with a first cylinder 15. The output end of the first cylinder 15 passes through the movable frame 14 and is fixedly connected to a connecting plate 16. The lower surface of the connecting plate 16 is fixedly connected to a clamping device 17. The side of the connecting plate 16 facing away from the horizontal plate 10 is slidably connected to the movable frame 14. The first cylinder 15 can drive the clamping device 17 to move up and down through the connecting plate 16, thereby lifting and lowering the blister tray, which is convenient for transfer and positioning. The sliding connection between the connecting plate 16 and the movable frame 14 ensures the stability and straightness of the up and down movement. The clamping device 17 is slidably connected to one side of the movable frame 14.

[0016] The clamping device 17 includes an upper support plate 31 and a slide rail 32. A clamping arm 34 is symmetrically slidably mounted on the lower surface of the upper support plate 31 and rotatably connected to a rotating plate 35. A slider 33 is slidably sleeved on the outer surface of the slide rail 32. The lower surface of the slider 33 is fixedly connected to the clamping arm 34. The cooperation between the slide rail 32 and the slider 33 provides guidance for the opening and closing action of the clamping arm 34, enabling the clamping arm 34 to slide smoothly along the direction of the slide rail 32 when clamping the blister tray. This ensures the accuracy and stability of the clamping action and helps improve the precision and reliability of the clamping. The outer surface of the 35 is symmetrically connected to inclined connecting rods 36. One end of each inclined connecting rod 36 is rotatably connected to two clamping arms 34. A second cylinder 37 is fixedly mounted on the lower surface of one clamping arm 34. The output end of the second cylinder 37 is fixedly connected to the other clamping arm 34. A clamping plate 38 is fixedly connected to the lower end of the clamping arm 34. Power is output through the first cylinder 15 to drive the connecting plate 16 to move up and down. Since the connecting plate 16 is fixedly connected to the clamping device 17, the clamping device 17 will move up and down together with the connecting plate 16. When it is necessary to clamp the blister tray, the clamping device 17 descends to the appropriate position. Under the action of the relevant driving mechanism, the clamping arm 34 performs opening and closing actions along the slide rail 32 to clamp or release the blister tray, thereby realizing the functions of clamping, transferring and positioning the blister tray, so that subsequent waste cutting and other processes can be carried out smoothly.

[0017] The cutting mechanism 19 includes a U-shaped plate 20. The lower surface of the U-shaped plate 20 is fixedly connected to the cutting table 18. A second guide rod 21 is symmetrically fixedly connected to one side of the upper surface of the cutting table 18. A sliding module 22 is slidably sleeved on the outer surface of the second guide rod 21. One side of the sliding module 22 is fixedly connected to the cutting blade 23. The cooperation between the second guide rod 21 and the sliding module 22 provides guidance for the up-and-down reciprocating movement of the cutting blade 23, so that the cutting blade 23 can move vertically up and down along a predetermined trajectory when cutting the waste material of the blister tray.

[0018] A rotating rod 24 is rotatably connected to the upper end of the U-shaped plate 20. A transmission box 26 is fixedly installed on the upper surface of the U-shaped plate 20. The rotating rod 24 passes through the transmission box 26. A second motor 27 is fixedly installed on the upper surface of the transmission box 26. The output end of the second motor 27 passes through the transmission box 26 and is fixedly sleeved with a second bevel gear 28. A first bevel gear 25 is fixedly sleeved on the outer surface of the rotating rod 24. The outer surface of the first bevel gear 25 meshes with the outer surface of the second bevel gear 28. Turntables 29 are fixedly connected to both ends of the rotating rod 24. A connecting rod 30 is rotatably connected to the outer surface of the turntables 29. The upper end of the connecting rod 30 is eccentrically rotatably connected to one side of the turntables 29. This eccentric rotatable connection allows the connecting rod 30 to... The sliding module 22 and the cutting blade 23 move in a stable up-and-down reciprocating motion, effectively cutting the waste material from the blister tray. This structural design helps to convert rotational motion into stable linear reciprocating motion. The lower end of the connecting rod 30 is fixedly connected to the cutting blade 23. The upper surface of the cutting table 18 has a cutting groove corresponding to the position of the cutting blade 23. The cutting groove on the cutting table 18 provides cutting space for the cutting blade 23, preventing the cutting blade 23 from colliding and rubbing against the surface of the cutting table 18 during the cutting process, thus protecting the cutting blade 23. The second motor 27 operates, and its output power is transmitted to the first bevel gear 25 through the second bevel gear 28 connected to it. The first bevel gear 25 drives the rotating rod 24 to rotate. The turntables 29 at both ends of the rotating rod 24 follow the rotation, and the connecting rod 30, which is eccentrically connected to the turntables 29, pushes the sliding module 22 to move up and down along the second guide rod 21. The sliding module 22 is connected to the cutting blade 23, ultimately driving the cutting blade 23 to perform up-and-down cutting action to cut the waste material from the blister tray.

[0019] Working principle: The first motor 40 drives the lead screw 13 to rotate. The moving frame 14, which is threadedly connected to the lead screw 13, will move horizontally in a straight line along the axial direction of the lead screw 13 under the action of the rotation of the lead screw 13. The output end of the first cylinder 15, which is fixedly installed on the upper surface of the moving frame 14, passes through the moving frame 14 and is fixedly connected to the connecting plate 16. The lower surface of the connecting plate 16 is fixedly connected to the clamping device 17. Therefore, when the moving frame 14 moves horizontally, it will drive the clamping device 17 to adjust its position horizontally on one side of the horizontal plate 10, so as to realize the horizontal handling and positioning of the blister tray. The first cylinder 15 can extend and retract. When the piston rod of the first cylinder 15 extends or retracts, it will drive the connecting plate 16 and the clamping device 17 connected to it to move vertically. When clamping a pallet, the first cylinder 15 can first descend to make the clamping plate 38 contact and clamp the pallet, and then rise to lift the pallet for subsequent transfer operations; when placing a pallet, the first cylinder 15 descends to place the pallet in the designated position, and then rises to reset.

[0020] When clamping is required, clamping arms 34 are symmetrically slidably mounted on the lower surface of the upper support plate 31 and rotatably connected to a rotating plate 35. Inclined connecting rods 36 are symmetrically rotatably connected to the outer surface of the rotating plate 35. The two inclined connecting rods 36 are rotatably connected to the two clamping arms 34 respectively. A second cylinder 37 is fixedly mounted on the lower surface of one of the clamping arms 34, and the output end of the second cylinder 37 is fixedly connected to the other clamping arm 34. When the second cylinder 37 is activated, it pushes or pulls the clamping arm 34 connected to it. Due to the connection between the inclined connecting rod 36 and the rotating plate 35, the two clamping arms 34 open and close synchronously. The clamping plate 38 fixedly connected to the lower end of the clamping arm 34 then clamps or releases the blister tray.

[0021] When cutting is required, the second motor 27 starts, and its output end passes through the transmission box 26 and is fixedly sleeved with the second bevel gear 28. The second bevel gear 28 meshes with the first bevel gear 25 fixedly sleeved on the outer surface of the rotating rod 24, thereby transmitting power from the second motor 27 to the rotating rod 24, causing the rotating rod 24 to rotate. Both ends of the rotating rod 24 are fixedly connected to turntables 29, and the outer surface of the turntables 29 is rotatably connected to connecting rods 30. One end of the connecting rod 30 is fixedly connected to a sliding module 22, which is slidably sleeved on the second guide rod 21. The upper surface of the cutting table 18 has a cutting groove corresponding to the position of the cutting blade 23. When the rotating rod 24 rotates, it drives the turntable 29 to make a circular motion. The turntable 29 drives the sliding module 22 to make a reciprocating motion up and down on the second guide rod 21 through the connecting rod 30, thereby causing the cutting blade 23, which is fixedly connected to the sliding module 22, to make a cutting motion up and down, cutting the blister tray waste placed on the cutting table 18 above the cutting groove.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
