Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, specifically a drilling device. Background Technology

[0002] Plastic bags are bags made primarily of plastic (common plastics include polypropylene, polyester, nylon, etc.). They are essential items in people's daily lives. During the production process of plastic bags, a punching device is needed to punch holes.

[0003] Existing punching devices require users to flatten the surface of plastic bags before punching. However, due to the material of the plastic bag, once it comes into contact with the drill bit, it is easy to cause wrinkles due to the pressure of the drill bit, which will cause the punching position to deviate and reduce the practicality of the device. Therefore, a punching device 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 drilling device of this utility model includes a support frame. A first motor is fixedly connected to the outside of the support frame. A lifting screw is fixedly connected to the output end of the first motor. A lifting plate is threadedly connected to the outside of the lifting screw. A drill bit is rotatably connected to the outside of the lifting plate. A first locking strip is fixedly connected to the inside of the drill bit. The first locking strip and the lifting screw are slidably connected. A second motor is fixedly connected to the outside of the support frame. A telescopic rod is fixedly connected to the output end of the second motor. The telescopic rod and the lifting plate are slidably connected. A first spur gear is fixedly connected to the outside of the telescopic rod. A gear ring meshes with the outside of the first spur gear. Both the gear ring and the first spur gear are rotatably connected to the lifting plate. A second spur gear meshes with the outside of the gear ring. A second locking strip is fixedly connected to the inside of the second spur gear. A sliding rod is slidably connected to the outside of the second locking strip. One end of the sliding rod is rotatably connected to... A pressure plate is used, with a spring fixedly connected to its outer side. One end of the spring is fixedly connected to a lifting plate, and one end of the sliding rod is fixedly connected to a spreading plate. This step involves setting up a drill bit, a first flat gear, a gear ring, a second flat gear, and a spreading plate. First, a plastic bag is placed inside the support frame. A first motor drives a lifting screw to rotate, which in turn moves the lifting plate and the drill bit. The sliding connection between the lifting screw and the first locking strip allows the lifting screw to rotate the first locking strip and the drill bit. Simultaneously, the lifting plate moves the spreading plate close to the plastic bag. Then, a second motor is started, driving the second flat gear to rotate. The second flat gear then rotates the second locking strip, which in turn rotates the spreading plate. The opposite rotation of the two spreading plates flattens the plastic bag. The drill bit then continues to move downwards to punch holes in the plastic bag. This allows the device to flatten and tighten the plastic bag during punching, improving the stability of the punching process.

[0006] Preferably, a cylinder is fixedly connected to the outside of the support frame, and a reinforcing plate is fixedly connected to the output end of the cylinder. By setting up the cylinder and the reinforcing plate, after a large number of plastic bags are piled up on the support frame, the cylinder can drive the reinforcing plate to move, thereby facilitating the pushing and positioning of the plastic bags, making it easier to align the punching position with the drill bit, and improving the convenience of device positioning and alignment.

[0007] Preferably, the surface of the support frame is provided with a placement groove, which is used in conjunction with the drill bit. A dust collection component is fixedly connected to the outside of the support frame, and the dust collection component is connected to the placement groove. By setting up the placement groove and the dust collection component, after the device punches a hole in the plastic bag, the dust collection component is activated. The dust collection component pulls the cut plastic bag out from the inside of the drill bit and falls into the inside of the placement groove, making it easier for the drill bit to separate from the plastic bag and improving the convenience of using the device.

[0008] Preferably, a baffle is slidably connected to the inner side of the support frame. The baffle works in conjunction with the drill bit. By setting the baffle, when the drill bit drills a hole in the plastic bag, the baffle can be moved to separate the plastic bag from the external environment, so that the airflow generated by the external environment can further move away from the plastic bag, thereby making the cutting of the plastic bag more stable and improving the stability of the device.

[0009] Preferably, a magnetic plate is fixedly connected to the outer side of the baffle. The magnetic plate works in conjunction with the support frame. By setting the magnetic plate, it is easy to pull the two baffles simultaneously for synchronous movement. This allows the user to clean the inside of the device after use. When the baffle moves to close the support frame, it can be attracted to the outside of the support frame by the magnetic plate, which facilitates further fixation of the baffle and the device's position, thus improving the stability of the device.

[0010] Preferably, a shock absorber is fixedly connected to the outside of the support frame, and a suction cup is fixedly connected to the outside of the shock absorber. This step, by setting the shock absorber and the suction cup, allows the device to be easily fixed at the installation location by adhering to the suction cup. When drilling holes in the device, the shock absorber can reduce the vibration experienced by the device, further improving the stability of the device in use.

[0011] The advantages of this utility model are:

[0012] 1. This utility model, by setting up a drill bit, a first flat gear, a gear ring, a second flat gear, and a spreading plate, first places a plastic bag inside the support frame. The first motor drives the lifting screw to rotate, which in turn drives the lifting plate and the drill bit to move. Through the sliding connection between the lifting screw and the first clamping strip, the lifting screw drives the first clamping strip and the drill bit to rotate. At the same time, the lifting plate drives the spreading plate to move close to the plastic bag. Then, the second motor is started, which drives the second flat gear to rotate, which in turn drives the second clamping strip to rotate, which in turn drives the spreading plate to rotate. Through the opposite rotation of the two spreading plates, the plastic bag is flattened. Then the drill bit continues to move down to punch holes in the plastic bag. This allows the device to flatten and tighten the plastic bag during punching, improving the stability of the device during punching.

[0013] 2. By setting up a cylinder and a reinforcing plate, this utility model allows the reinforcing plate to be moved by the cylinder after a large number of plastic bags are piled up on the support frame. This facilitates the pushing and positioning of the plastic bags, making it easier to align the punching position with the drill bit and improving the convenience of positioning and alignment 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 Figure 1-5As shown, a drilling device includes a support frame 1. A first motor 2 is fixedly connected to the outside of the support frame 1. A lifting screw 3 is fixedly connected to the output end of the first motor 2. A lifting plate 4 is threadedly connected to the outside of the lifting screw 3. A drill bit 5 is rotatably connected to the outside of the lifting plate 4. A first locking strip 6 is fixedly connected to the inside of the drill bit 5. The first locking strip 6 and the lifting screw 3 are slidably connected. A second motor 7 is fixedly connected to the outside of the support frame 1. A telescopic rod 8 is fixedly connected to the output end of the second motor 7. The telescopic rod 8 and the lifting plate 4 are slidably connected. A first spur gear 9 is fixedly connected to the outside of the telescopic rod 8. A gear ring 10 meshes with the outside of the first spur gear 9. Both the gear ring 10 and the first spur gear 9 are rotatably connected to the lifting plate 4. A second spur gear 11 meshes with the outside of the gear ring 10. A second locking strip 12 is fixedly connected to the inside of the second spur gear 11. A slide rod 13 is slidably connected to the outside of the second locking strip 12. A pressure plate 14 is rotatably connected to one end of the slide rod 13. A [missing information - likely a device name] is fixedly connected to the outside of the pressure plate 14. Spring 15, one end of which is fixedly connected to lifting plate 4, and sliding rod 13, one end of which is fixedly connected to spreading plate 16. This step involves setting up drill bit 5, first flat gear 9, gear ring 10, second flat gear 11, and spreading plate 16. First, a plastic bag is placed inside the support frame 1. The first motor 2 drives the lifting screw 3 to rotate, which in turn drives the lifting plate 4 and drill bit 5 to move. Through the sliding connection between the lifting screw 3 and the first locking strip 6, the lifting screw 3 drives the first locking strip 6 and drill bit 5. The device rotates while simultaneously moving the flat plate 16 close to the plastic bag via the lifting plate 4. Then, the second motor 7 is started, which drives the second flat gear 11 to rotate. The second flat gear 11 drives the second clamping bar 12 to rotate, which in turn drives the flat plate 16 to rotate. The opposite rotation of the two flat plates 16 flattens the plastic bag. Then, the drill bit 5 continues to move down to punch holes in the plastic bag. This allows the device to flatten and tighten the plastic bag during punching, improving the stability of the punching process.

[0024] Furthermore, such as Figure 1 As shown, a cylinder 17 is fixedly connected to the outside of the support frame 1, and a reinforcing plate 18 is fixedly connected to the output end of the cylinder 17. By setting up the cylinder 17 and the reinforcing plate 18, after a large number of plastic bags are piled up on the support frame 1, the cylinder 17 can drive the reinforcing plate 18 to move, thereby facilitating the pushing and positioning of the plastic bags, making it easier to align the drilling position with the drill bit 5, and improving the convenience of device positioning and alignment.

[0025] Furthermore, such as Figure 1 and Figure 2As shown, the support frame 1 has a placement groove 19 on its surface. The placement groove 19 is used in conjunction with the drill bit 5. A dust collection component 20 is fixedly connected to the outside of the support frame 1. The dust collection component 20 is connected to the placement groove 19. In this step, by setting up the placement groove 19 and the dust collection component 20, after the device punches a hole in the plastic bag, the dust collection component 20 is activated. The dust collection component 20 drives the cut plastic bag to be sucked out from the inside of the drill bit 5 and fall into the inside of the placement groove 19, making it easier for the drill bit 5 to separate from the plastic bag and improving the convenience of using the device.

[0026] Furthermore, such as Figure 1 As shown, a baffle 21 is slidably connected to the inner side of the support frame 1. The baffle 21 is used in conjunction with the drill bit 5. By setting the baffle 21, when the drill bit 5 drills a hole in the plastic bag, the baffle 21 can be moved to separate the plastic bag from the outside environment, so that the air flow generated by the outside environment can be further away from the plastic bag, thereby making the cutting of the plastic bag more stable and improving the stability of the device.

[0027] Furthermore, such as Figure 1 As shown, a magnetic plate 22 is fixedly connected to the outer side of the baffle 21. The magnetic plate 22 works in conjunction with the support frame 1. By setting the magnetic plate 22, it is easy to pull the two baffles 21 simultaneously for synchronous movement. This allows the user to clean the inside of the device after use. When the baffle 21 moves to close the support frame 1, it can be attracted to the outside of the support frame 1 by the magnetic plate 22, which facilitates further fixation of the support frame 1 and the position of the baffle 21, thus improving the stability of the device.

[0028] Furthermore, such as Figure 2 As shown, a shock absorber 23 is fixedly connected to the outside of the support frame 1, and a suction cup 24 is fixedly connected to the outside of the shock absorber 23. This step, by setting the shock absorber 23 and the suction cup 24, allows the device to be easily fixed by adhering to the installation location through the suction cup 24. When drilling holes in the device, the shock absorber 23 can reduce the vibration experienced by the device, further improving the stability of the device in use.

[0029] The working principle is as follows: First, the plastic bag is placed inside the support frame 1. The first motor 2 drives the lifting screw 3 to rotate, which in turn moves the lifting plate 4 and the drill bit 5. Through the sliding connection between the lifting screw 3 and the first clamping strip 6, the lifting screw 3 drives the first clamping strip 6 and the drill bit 5 to rotate. At the same time, the lifting plate 4 drives the sliding rod 13 to move, which in turn moves the spreading plate 16 to be close to the plastic bag. Then, the second motor 7 is started, which drives the telescopic rod 8 to rotate. The telescopic rod 8 drives the first spur gear 9 to rotate, which in turn drives the gear ring 10 to rotate. The gear ring 10 drives the second spur gear 11 to rotate, which in turn drives the second clamping strip 12 to rotate. The second clamping strip 12 drives the spreading plate 16 to rotate. Through the opposite rotation of the two spreading plates 16, the plastic bag is flattened. Then, the drill bit 5 continues to move down to drill holes in the plastic bag.
