Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum tube processing technology, specifically a cutting device for processing aluminum tubes for medical ointments. Background Technology
[0002] Pharmaceutical aluminum tubes can be divided into two types: soft aluminum tubes and hard aluminum cans. Soft aluminum tubes are used to package external ointment products such as eye ointments, eye creams, balms, and Picon creams. Therefore, during the production of pharmaceutical ointment aluminum tubes, longer aluminum tubes need to be circumferentially cut to facilitate subsequent processing for filling with ointment.
[0003] However, because the aluminum tube of ointment is relatively soft, it is prone to collapse during the fixing and cutting process, resulting in cutting deviations and affecting the production quality. Therefore, a cutting device for processing aluminum tubes of medical ointment is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A cutting device for processing aluminum tubes of medical ointment, comprising a base, a first motor fixedly connected to the outer side of the base, a gear fixedly connected to the output end of the first motor, a gear meshing with a gear ring on the outer side of the gear, a support plate fixedly connected to the outer side of the gear ring, a support rod rotatably connected to the inner side of the support plate, the support rod being fixedly connected to the base, a hydraulic cylinder fixedly connected to the outer side of the support plate, a movable plate fixedly connected to the output end of the hydraulic cylinder, a second motor fixedly connected to the outer side of the movable plate, and a ring cutter fixedly connected to the output end of the second motor; this step involves setting up a gear, a gear ring, and a support... The device consists of a support rod, a hydraulic cylinder, and a ring cutter. First, a suitably sized soft aluminum tube is fitted onto the outside of the support rod, which then presses against the inner wall of the tube, providing support. Next, the hydraulic cylinder moves a movable plate and the ring cutter, ensuring the ring cutter is flush against the tube. A second motor rotates the ring cutter, which in turn starts a first motor. This first motor drives a gear, which in turn drives a gear ring, which in turn drives a support plate to rotate around the support rod. This causes the support rod to rotate and cut the ring cutter around the soft aluminum tube, cutting it to the appropriate length. This system supports the tube in a fixed shape during cutting, preventing collapse and improving the stability of the cutting process.
[0006] Preferably, a reinforcing screw is rotatably connected to the inner side of the movable plate, a movable frame is threadedly connected to the outer side of the reinforcing screw, and a roller is rotatably connected to the inner side of the movable frame. This step, by setting up the reinforcing screw, movable frame, and roller, allows the user to hold and fix the movable frame when the soft aluminum tube is sleeved on the outside of the support rod. Rotating the reinforcing screw drives the movable frame and roller to move, causing the roller to move to fit tightly against the outer wall of the soft aluminum tube. Thus, when the soft aluminum tube is cut, the roller clamps and fixes it, making the position of the soft aluminum tube more stable, making the cutting more stable, and improving the stability of the device.
[0007] Preferably, a limiting rod is fixedly connected to the outside of the movable frame, and the limiting rod is slidably connected to the movable plate. This step, by setting the limiting rod, allows the movable frame to move by inserting the limiting rod into the inside of the movable plate, thereby restricting the position of the movable frame and making its movement more stable. This eliminates the need for the user to clamp and fix the movable frame, improving the ease of use of the device.
[0008] Preferably, a push ring is slidably connected to the outer side of the support plate, and the push ring is slidably connected to the support rod. This step, by setting the push ring, allows the soft aluminum tube to be pushed after it has been cut, so that the cut soft aluminum tube can be separated from the support rod, thus improving the convenience of using the device.
[0009] Preferably, a magnetic plate is fixedly connected to the outer side of the push ring, and the magnetic plate and the support plate are used in conjunction. This step, by setting the magnetic plate, allows the push ring to be attracted to the outer side of the support plate when it is not in use, thereby restricting the position of the push ring and making it less likely to be affected by the rotation of the support plate, thus improving the stability of the device.
[0010] Preferably, a mounting plate is fixedly connected to the outer side of the base, and a mounting groove is formed on the surface of the mounting plate. This step, by setting the mounting plate and the mounting groove, makes it easier to mechanically fix the device by screwing screws into the mounting groove and the mounting location during installation, thereby improving the convenience of device installation.
[0011] The advantages of this utility model are:
[0012] 1. This utility model, by setting up gears, gear rings, support rods, hydraulic cylinders, and ring cutters, first places a soft aluminum tube of appropriate size on the outside of the support rod, and the support rod is pressed against the inner wall of the soft aluminum tube to support it. Then, the hydraulic cylinder drives the movable plate and the ring cutter to move, so that the ring cutter is pressed against the soft aluminum tube. The second motor drives the ring cutter to rotate, and then the first motor is started. The first motor drives the gear to rotate, and the gear drives the gear ring to rotate. The gear ring drives the support plate to rotate around the support rod, so that the support rod drives the ring cutter to rotate and cut around the soft aluminum tube, so that the soft aluminum tube is cut into appropriate lengths. This allows the soft aluminum tube to be supported in a fixed shape during cutting, making it less likely to collapse and affect the cutting, thus improving the cutting stability of the device.
[0013] 2. This utility model, by setting up a reinforcing screw, a movable frame, and a roller, allows the user to hold and fix the movable frame when the soft aluminum tube is sleeved on the outside of the support rod. Rotating the reinforcing screw drives the movable frame and roller to move, causing the roller to move close to the outer wall of the soft aluminum tube. Thus, when the soft aluminum tube is being cut, the roller clamps and fixes it, making the position of the soft aluminum tube more stable, making the cutting more stable, and improving the stability of the device.

[0021] 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 scope of protection of the present utility model.
[0022] Specific implementation examples are given below.
[0023] Please see Figures 1 to 5 As shown, a cutting device for processing aluminum tubes of medical ointment includes a base 1. A first motor 2 is fixedly connected to the outer side of the base 1. A gear 3 is fixedly connected to the output end of the first motor 2. A gear ring 4 meshes with the outer side of the gear 3. A support plate 5 is fixedly connected to the outer side of the gear ring 4. A support rod 6 is rotatably connected to the inner side of the support plate 5. The support rod 6 is fixedly connected to the base 1. A hydraulic cylinder 7 is fixedly connected to the outer side of the support plate 5. A movable plate 8 is fixedly connected to the output end of the hydraulic cylinder 7. A second motor 9 is fixedly connected to the outer side of the movable plate 8. A ring cutter 10 is fixedly connected to the output end of the second motor 9. This step involves setting up the gear 3, gear ring 4, support rod 6, hydraulic cylinder 7, and ring cutter 10. First, a soft aluminum tube of appropriate size is fitted onto the outside of the support rod 6. The support rod 6 is then pressed tightly against the inner wall of the soft aluminum tube, thus supporting the tube. Next, the hydraulic cylinder 7 drives the movable plate 8 and the ring cutter 10 to move, so that the ring cutter 10 is pressed tightly against the soft aluminum tube. The second motor 9 drives the ring cutter 10 to rotate. Then, the first motor 2 is started, which drives the gear 3 to rotate. The gear 3 drives the gear ring 4 to rotate, which in turn drives the support plate 5 to rotate around the support rod 6. This causes the support rod 6 to drive the ring cutter 10 to rotate and cut around the soft aluminum tube, cutting it into appropriate lengths. This ensures that the soft aluminum tube is supported in a fixed shape during cutting, making it less likely to collapse and affect the cutting process, thus improving the stability of the cutting device.
[0024] Furthermore, such as Figure 1As shown, a reinforcing screw 11 is rotatably connected to the inner side of the movable plate 8, and a movable frame 12 is threadedly connected to the outer side of the reinforcing screw 11. A roller 13 is rotatably connected to the inner side of the movable frame 12. This step, by setting up the reinforcing screw 11, the movable frame 12, and the roller 13, allows the user to hold and fix the movable frame 12 when the soft aluminum tube is sleeved on the outside of the support rod 6. Rotating the reinforcing screw 11 drives the movable frame 12 and the roller 13 to move, so that the roller 13 moves to fit tightly against the outer wall of the soft aluminum tube. Thus, when the soft aluminum tube is cut, the roller 13 clamps and fixes it, making the position of the soft aluminum tube more stable, making the cutting more stable, and improving the stability of the device.
[0025] Furthermore, such as Figure 1 As shown, a limiting rod 14 is fixedly connected to the outside of the movable frame 12, and the limiting rod 14 is slidably connected to the movable plate 8. This step, by setting the limiting rod 14, allows the movable frame 12 to move by inserting the limiting rod 14 into the inside of the movable plate 8, thereby restricting the position of the movable frame 12, making the movement of the movable frame 12 more stable, and eliminating the need for the user to clamp and fix the movable frame 12, thus improving the convenience of using the device.
[0026] Furthermore, such as Figure 1 As shown, a push ring 15 is slidably connected to the outer side of the support plate 5, and the push ring 15 is slidably connected to the support rod 6. This step, by setting the push ring 15, allows the soft aluminum tube to be pushed after it has been cut, so that the cut soft aluminum tube can be separated from the support rod 6, thus improving the convenience of using the device.
[0027] Furthermore, such as Figure 1 As shown, a magnetic plate 16 is fixedly connected to the outside of the push ring 15, and the magnetic plate 16 and the support plate 5 are used together. By setting the magnetic plate 16, the push ring 15 can be attracted to the outside of the support plate 5 when it is not in use, thereby restricting the position of the push ring 15 and making it less likely to be affected by the rotation of the support plate 5, thus improving the stability of the device.
[0028] Furthermore, such as Figure 1 As shown, a mounting plate 17 is fixedly connected to the outer side of the base 1, and a mounting groove 18 is provided on the surface of the mounting plate 17. This step, by setting the mounting plate 17 and the mounting groove 18, makes it easier to mechanically fix the device by screwing the screws into the mounting groove 18 and the mounting location during installation, thereby improving the convenience of device installation.
[0029] The working principle is as follows: First, a soft aluminum tube of appropriate size is fitted onto the outside of the support rod 6. The support rod 6 is pressed against the inner wall of the soft aluminum tube, thus supporting the tube. Rotating the reinforcing screw 11 moves the moving frame 12 and the roller 13, causing the roller 13 to press against the outer wall of the soft aluminum tube. During cutting, the roller 13 clamps and fixes the soft aluminum tube. Then, the hydraulic cylinder 7 moves the movable plate 8 and the ring cutter 10, causing the ring cutter 10 to press against the soft aluminum tube. The second motor 9 drives the ring cutter 10 to rotate. Then, the first motor 2 is started, which drives the gear 3 to rotate. The gear 3 drives the gear ring 4 to rotate, which in turn drives the support plate 5 to rotate around the support rod 6. This causes the support rod 6 to drive the ring cutter 10 to rotate and cut around the soft aluminum tube, cutting the tube into appropriate lengths. This ensures that the soft aluminum tube is supported in a fixed shape during cutting, preventing it from collapsing and affecting the cutting process.
