Description

Technical Field

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

[0002] Plastic blister packs are a type of plastic product widely used for packaging, securing, and protecting items. To meet diverse size and shape requirements, they often need to be cut using cutting devices.

[0003] However, traditional blister pack cutting devices often employ a single-station design, which means that after cutting, the device must wait for the downstream conveying components to remove the cut blister pack before the next material can be cut. This process prolongs the waiting time and reduces overall production efficiency. In addition, materials are prone to shifting during the cutting process of traditional devices, which significantly affects the accuracy of cutting. Even more troublesome is that the scraps generated after cutting are easily left on the cutting table, which is not only difficult to clean but also increases the cost and time of manual cleaning.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] This invention features a material pushing assembly. Motor 1 drives a lead screw to rotate, converting the screw's rotational motion into linear motion of drive block 1. This ensures stable material pushing between conveyor 1 and conveyor 2, enabling dual-station cutting and improving production efficiency. Secondly, the transmission system composed of motor 2, a rotating shaft, gears, and a rack, combined with the guiding effect of guide rail 2, allows the pusher plate to rise safely and smoothly to a safe height after completing its pushing task, preventing collisions with subsequent materials. Subsequently, through the coordinated work of motors 1 and 2, the pusher plate can quickly return to its initial position, preparing for the next pushing operation, enhancing the safety and reliability of the equipment. Furthermore, the transmission system of motor 2, a rotating shaft, gears, and a rack can adjust the height of the pusher plate to accommodate materials of different thicknesses, improving the equipment's adaptability and flexibility.

[0013] This invention features a cutting assembly with a hydraulic cylinder driving the cutting blades to move vertically, ensuring the stability and precision of the cutting action. Simultaneously, the combined use of vacuum device one and vacuum suction cup one prevents material displacement during cutting while also adhering to scraps. When the hydraulic cylinder's telescopic rod retracts, vacuum suction cup one lifts the scraps, separating them from the suction cup. Then, the telescopic rod of telescopic cylinder one extends, driving drive block two and its bottom components to move along guide rail three, removing the scraps from the cutting assembly. This avoids the problem of scraps remaining on the cutting table and being difficult to clean, improving production efficiency and reducing manual cleaning costs and time. Furthermore, the combination of telescopic cylinder two and vacuum suction cup two on the cutting base stably adsorbs the suction cup portion of the material, ensuring cutting accuracy.

[0025] The cutting assembly 6 includes a pair of telescopic cylinders 61 disposed at the bottom of the mounting plate 5. The telescopic cylinders 61 extend and retract via telescopic rods, driving a second driving block 62 to move. The second driving block 62 is mounted on the top of the telescopic rods of the two cylinders 61, providing a mounting base for the hydraulic cylinder 64. A guide rail 63 is disposed at the bottom of the mounting plate 5, and the second driving block 62 is slidably mounted on the guide rail 63, which provides a stable sliding track for the second driving block 62. A hydraulic cylinder 64 is disposed at the bottom of the second driving block 62, and the hydraulic cylinder 64 is used to drive the mounting plate 65 and the cutting assembly 62. The lifting and lowering of the scissors 66 realizes the cutting action. The bottom of the telescopic rod of the hydraulic cylinder 64 is equipped with a second mounting plate 65, which provides a mounting base for the cutting scissors 66. Several cutting scissors 66 are set at the bottom of the second mounting plate 65. The cutting scissors 66 are used to cut materials. A vacuum device 67 is set on one side of the top of the second mounting plate 65. Vacuum suction cups 68 are set around the bottom of the second mounting plate 65. The vacuum device 67 and the vacuum suction cups 68 are connected by a connecting pipe. The combination of the vacuum device 67 and the vacuum suction cups 68 can be used to absorb the scraps generated after cutting.

[0026] Cutting seats 69 are provided on one side of conveyor 1 and conveyor 2, corresponding to the position of mounting plate 2 65. The cutting seats 69 have mounting grooves 610, which provide the mounting base for telescopic cylinder 2 611. Telescopic cylinder 2 611 is provided around the inside of the mounting groove 610. The telescopic rod of telescopic cylinder 2 611 drives the mounting plate 3 612 to rise and fall. Mounting plate 3 612 is provided on the top of the telescopic rod of several telescopic cylinder 2 611. Mounting plate 3 612 provides the mounting base for vacuum equipment 2 615 and vacuum suction cup 2 616. A pair of sliders 613 are symmetrically arranged on both sides of mounting plate 3 612. Guide rails 4 614 are provided on the inner wall of the cutting seats 69 on both sides of the mounting groove 610. The sliders 613 on the same side are slidably arranged in the guide rails 4 614. The combination of sliders 613 and guide rails 4 614 ensures the stability of mounting plate 3 612 when it rises and falls, and ensures that vacuum suction cup 2 616 can stably adsorb plastic trays.

[0027] A vacuum device 615 is installed at the bottom of the mounting plate 612. Vacuum suction cups 616 are installed on the mounting plate 612 at positions corresponding to the cutting scissors 66. The vacuum device 615 and vacuum suction cups 616 are connected by a connecting pipe. The combination of vacuum device 615 and vacuum suction cups 616 can be used to adsorb the plastic tray on the material, ensuring the accuracy of cutting. A cover plate 617 is installed on the top of the cutting seat 69. The cover plate 617 has mounting holes corresponding to the vacuum suction cups 616. The cover plate 617 helps the material to be smoothly transferred onto the cutting seat 69, and the mounting holes allow the vacuum suction cups 616 to pass through.

[0028] In operation, conveyor 1 transports the material to be cut. When the first piece of material is delivered to the cutting seat 69 on the left, the telescopic rod of telescopic cylinder 611 extends, driving mounting plate 612 to rise along guide rail 614. Several vacuum suction cups 616 pass through the mounting holes on cover plate 617 and contact the suction cups on the material to be cut. Simultaneously, vacuum equipment 615 is activated, and vacuum suction cups 616 adsorb the suction cups. Then, the telescopic rod of hydraulic cylinder 64 extends, causing mounting plate 65 and cutting shears 66 to descend and cut the material. At the same time, vacuum equipment 67 is activated, and the installation... Vacuum suction cups 68 around the bottom of plate 2 65 adsorb the scraps generated after cutting. Then, the extension rod of hydraulic cylinder 64 retracts, causing the scraps to rise and separate from the suction cup. Then, the extension rod of extension cylinder 61 extends, causing drive block 2 62 and the components installed at its bottom to move along guide rail 3 63, removing the scraps from the overall equipment. Vacuum device 67 closes, releasing the scraps. At the same time, vacuum device 67 closes, releasing the cut suction cup. Downstream handling equipment transports the suction cup and stacks it. Cutting component 6 resets to prepare for cutting the next material.

[0029] When the first material is conveyed to the left cutting seat 69, conveyor 1 continues to convey the second material. Motor 35 drives the lead screw 34 to rotate, converting the rotational motion of the lead screw 34 into the linear motion of the drive block 36. This causes the drive block 36 and other components mounted at its bottom to move along guide rail 37, thereby enabling the pusher plate 315 to stably push the second material to conveyor 2. Conveyor 2 then conveys the second material to the right cutting seat 69 and operates according to the same steps as the left cutting seat 69. After the material is pushed, the rotating shaft 310 and gear 311 are driven to rotate by motor 2 39. Gear 311 transmits power to rack 312 through meshing, causing rack 312 and push plate 315 to rise to a safe height along guide rail 2 313. Then, push plate 315 is returned to the initial position by starting motor 1 35. After returning to the initial position, push plate 315 is returned to the initial height by starting motor 2 39 again, so as to carry out the next material push. The dual-station cutting reduces the waiting time of cutting component 6 for material loading and improves production efficiency.
