Description

Technical Field

[0002] Pharmaceutical packaging bag shearing and hot-pressing equipment is mainly used in pharmaceutical companies' flexible packaging production lines. It involves the automated processing of various pharmaceutical packaging bag materials such as plastic film and aluminum-plastic composite film. Through precise shearing, the packaging bag material is formed into a specified size and shape, and then the hot-pressing process is used to seal the packaging bag to meet the quality requirements of pharmaceutical packaging such as sealing, moisture protection, and pollution prevention. This ensures the stability and safety of pharmaceuticals during storage, transportation, and sales, while also improving the production efficiency and standardization of pharmaceutical packaging and promoting the automation and intelligent development of the packaging process in the pharmaceutical industry. Therefore, a pharmaceutical packaging bag shearing and hot-pressing equipment is particularly needed.

[0003] Traditional pharmaceutical packaging bag cutting and heat-pressing devices lack an effective pre-compression and fixing mechanism when performing heat-pressing and cutting operations, making it difficult to keep the packaging bags stable. During processing, the bags are prone to shifting. This positional deviation not only leads to inaccurate cutting dimensions and inaccurate heat-pressing positions, but also frequent adjustments to the packaging bag position will interrupt the processing flow, greatly reducing the overall packaging processing efficiency and hindering the efficient operation and quality control of pharmaceutical packaging production.

[0019] 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.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a cutting and pressing device for pharmaceutical packaging bags, including a base 1, a column 2 fixedly connected to the lower surface of the base 1, a pad 3 fixedly connected to the lower surface of the column 2, a fixing plate 4 fixedly connected to one side surface of the base 1, a support frame 5 fixedly connected to one side surface of the fixing plate 4, a crossbeam 6 fixedly connected to one side surface of the support frame 5, a cutting and pressing mechanism 7 provided on the lower surface of the crossbeam 6, and a fixing mechanism 8 provided on the upper surface of the base 1;

[0021] The fixing mechanism 8 includes a first slide groove 801, a slider 802, a base 803, a support plate 804, a connecting rod 805, a fixing plate 806, a first cylinder 807, a pivot 808, a swing rod 809, a rotating shaft 810, a pressure plate 811, a sliding rod 812, a motor 813, a double-acting lead screw 814, and a limiting block 815. The upper surface of the base 1 is provided with the first slide groove 801. The slider 802 is fixedly connected to the inner surface of the first slide groove 801. The upper surface of the slider 802 is fixedly connected to the base 803. The upper surface of the base 803 is fixedly connected to the support plate 804. A connecting rod 805 is fixedly connected to one side surface of the support plate 804. A fixing plate 806 is fixedly connected to one side surface of cylinder 5. A first cylinder 807 is fixedly connected to one side surface of the fixing plate 806. A pivot 808 is fixedly connected to one side surface of the first cylinder 807. A rocker arm 809 is fixedly connected to one side surface of the pivot 808. A rotating shaft 810 is fixedly connected to one side surface of the rocker arm 809. A pressure plate 811 is connected through the outer surface of the rotating shaft 810. A sliding rod 812 is fixedly connected to one side surface of the pressure plate 811. A motor 813 is fixedly connected to one side surface of the slider 802. A bidirectional lead screw 814 is driven through one side surface of the motor 813. A limit block 815 is fixedly connected to one side surface of the bidirectional lead screw 814. The system comprises a slide groove 801, a slider 802, a base 803, a support plate 804, a connecting rod 805, a fixing plate 806, a first cylinder 807, a pivot 808, a swing rod 809, a rotating shaft 810, a pressure plate 811, a sliding rod 812, a motor 813, a double-acting screw 814, and a limiting block 815. During use, when it is necessary to cut, heat-press, and fix the pharmaceutical packaging bag, the motor 813 is started, driving the double-acting screw 814 to rotate. Because the slider 802 cooperates with the first slide groove 801 and is connected to the base 803, the rotation of the double-acting screw 814 causes the slider 802 to move along the first slide groove 801, thereby driving the symmetrical fixing mechanism. The mechanism 8 moves to the appropriate position in the middle, aligning the pressure plate 811 with the part of the medicine packaging bag that needs to be fixed. Then, the first cylinder 807 starts to work, and its telescopic movement pushes the swing rod 809 to rotate around the rotating shaft 810 through the pivot 808. The rotation of the swing rod 809 drives the pressure plate 811 to move downward. At the same time, the sliding rod 812, which is fixedly connected to the pressure plate 811, slides along the corresponding guide structure on the support plate 804 to ensure that the pressure plate 811 is stably fixed until the pressure plate 811 presses the medicine packaging bag tightly onto the worktable below, completing the pre-pressing and fixing of the packaging bag, preventing deviation during processing, and reducing the need for frequent interruptions in processing for adjustment due to packaging bag deviation.

[0022] Furthermore, four sets of columns 2 are symmetrically arranged around the central axis of the base 1, and two sets of support frames 5 are symmetrically arranged around the central axis of the base 1. With the arrangement of columns 2, the four sets of columns 2 are symmetrically arranged around the central axis of the base 1 during use, which can provide stable support for the entire device from multiple directions, effectively dispersing various stresses generated during the operation of the device, and preventing the device from shaking, tilting or even tipping over due to uneven force.

[0023] Furthermore, the support frame 5 is threadedly connected to the base 1 via the fixing plate 4. The fixing components of the fixing mechanism 8 are symmetrically arranged in four sets around the central axis of the base 1. Through the setting of the fixing plate 4, the threaded connection can provide greater friction and connection force during use, so that the support frame 5 is firmly fixed on the base 1. During the operation of the pharmaceutical packaging bag cutting and pressing device, this connection method can also effectively prevent the support frame 5 from loosening or shifting, thereby ensuring the stability and reliability of the entire device structure.

[0024] Furthermore, the inner wall size of the first groove 801 matches the outer wall size of the slider 802. Two sets of support plates 804 are symmetrically arranged around the central axis of the base 803. With the support plates 804 arranged, during use, the two sets of support plates 804 are symmetrically arranged around the central axis of the base 803, which can evenly distribute the pressure from the first cylinder 807, pressure plate 811, etc. in the upper fixing mechanism 8, as well as the pressure generated during the fixing of the medicine packaging bag, to the base 803, effectively preventing local deformation or damage to the base 803 due to uneven force.

[0025] Furthermore, the swing arm 809 forms a rotating structure with the pivot 808 and the rotating shaft 810 through the first cylinder 807. The pressure plate 811 is equipped with a rubber pad. When the pressure plate 811 is pressed down to fix the medicine packaging bag during use, the rubber pad is in direct contact with the packaging bag, which can effectively prevent the hard surface of the pressure plate 811 from causing scratches, indentations or damage to the packaging bag.

[0026] Furthermore, the shearing and pressing mechanism 7 includes a second cylinder 701, a blade holder 702, a limiting post 703, a shearing blade 704, a sliding groove 705, an electric heating plate 706, a cutting groove 707, and a scale 708. The second cylinder 701 is fixedly connected to the lower surface of the crossbeam 6. The blade holder 702 is fixedly connected to the lower surface of the second cylinder 701. The limiting post 703 is fixedly connected to the upper surface of the blade holder 702. The shearing blade 704 is fixedly connected to the lower surface of the blade holder 702. The sliding groove 705 is fixedly connected to one side surface of the blade holder 702. The electric heating plate 706 is fixedly connected to the upper surface of the base 1. The cutting groove 707 is fixedly connected to one side surface of the electric heating plate 706. The scale 708 is fixedly connected to one side surface of the electric heating plate 706. The mechanism utilizes the second cylinder 701, blade holder 702, limiting post 703, and shearing blade 704. 04. The setting of the sliding groove 705, electric heating plate 706, cutting groove 707, and scale 708 is as follows: During use, when it is necessary to perform cutting and hot pressing operations on the pharmaceutical packaging bag, the second cylinder 701 is activated. The second cylinder 701 extends and pushes the knife holder 702 downward. Under the guidance of the sliding groove 705, the knife holder 702 moves smoothly downward. The shearing blade 704 below first contacts the packaging bag and performs a cutting action, cutting the packaging bag according to the predetermined size. At the same time, the knife holder 702 continues to move downward. When the shearing blade 704 cuts into the cutting groove 707, the electric heating plate 706 performs hot pressing and sealing operations on the edge of the cut packaging bag, completing the entire cutting and hot pressing process. During the up and down movement of the knife holder 702, the limiting post 703 plays a role in limiting the stroke range of the knife holder 702 to prevent excessive movement from causing equipment damage or affecting processing accuracy.

[0027] Furthermore, the shearing blade 704 forms a lifting structure with the blade holder 702 and the second cylinder 701. Two sets of limiting posts 703 are symmetrically arranged around the central axis of the blade holder 702. With the arrangement of the second cylinder 701, the blade holder 702 and the shearing blade 704, during use, the second cylinder 701 drives the blade holder 702, which in turn drives the shearing blade 704 to move up and down. This enables precise control of the position of the shearing blade 704. During the shearing process, the stroke of the second cylinder 701 can be precisely adjusted according to the material and thickness of the packaging bag and the predetermined shearing size, so that the shearing blade 704 can be lowered to a suitable height for the shearing operation.

[0028] Working principle: According to work requirements, through the setting of base 1, when it is necessary to cut, heat press and fix the medicine packaging bag, the motor 813 is started, driving the bidirectional lead screw 814 to rotate. Since the slider 802 cooperates with the first slide groove 801 and the slider 802 is connected to the base 803 and other components, the rotation of the bidirectional lead screw 814 will cause the slider 802 to move along the first slide groove 801, thereby driving the symmetrical fixing mechanism 8 to move to the appropriate position in the middle, so that the pressure plate 811 is aligned with the part of the medicine packaging bag that needs to be fixed. Then, the first cylinder 807 starts to work, and its extension and retraction movement Pivot 808 drives the rocker arm 809 to rotate around the pivot 810. The rotation of the rocker arm 809 causes the pressure plate 811 to move downward. At the same time, the sliding rod 812, which is fixedly connected to the pressure plate 811, slides along the corresponding guide structure on the support plate 804 to ensure that the pressure plate 811 is stably fixed until the pressure plate 811 presses the medicine packaging bag tightly onto the worktable below. The rubber pad on the pressure plate 811 protects the surface of the packaging bag and enhances friction, thereby completing the pre-pressing and fixing of the packaging bag, preventing displacement during processing, and reducing frequent interruptions in processing due to packaging bag displacement. After the packaging bag is secured, the shearing and hot-pressing mechanism 7 below the crossbeam 6 begins operation. The second cylinder 701 is activated, extending to push the blade holder 702 downwards. Guided by the sliding groove 705, the blade holder 702 smoothly descends. The shearing blade 704 below it first contacts the packaging bag and performs a shearing action, cutting the bag to the predetermined size. Simultaneously, the blade holder 702 continues to descend. When the shearing blade 704 cuts into the cutting groove 707, the electric heating plate 706 hot-presses and seals the edges of the cut packaging bag, completing the entire shearing and hot-pressing process. During the pressing process, as the tool holder 702 moves up and down, the limiting post 703 limits the stroke range of the tool holder 702 to prevent excessive movement from damaging the equipment or affecting the processing accuracy. The scale 708 on one side of the electric heating plate 706 can help the operator to pre-determine the position of the cutting and pressing, ensuring the accuracy and standardization of the entire process. This completes the use of a cutting and pressing device for pharmaceutical packaging bags. The second cylinder 701 and the first cylinder 807 are model XYDHA24-800, and the motor 813 is model YE2-132S-4.
