Abstract
Description
Technical Field
[0001] This utility model relates to a desiccant punching device, specifically a punching device for desiccant bags. Background Technology
[0002] Dryer bags need to be perforated to allow air to pass between the desiccant and the outside environment. However, current perforation equipment often only allows for the creation of holes of a single diameter, limiting its applicability. Utility Model Content
[0003] This invention provides a perforation device for desiccant bags to address the deficiencies in the prior art.
[0004] This utility model is achieved through the following technical solution:
[0005] A perforation device for desiccant bags includes a base plate supported by a column. A vertical plate is vertically connected to one side of the base plate, and a horizontal plate is vertically connected to the upper end of the vertical plate. One end of an electric telescopic rod is fixedly connected to the bottom surface of the horizontal plate, and the other end of the electric telescopic rod is fixedly connected to a first pressure plate. A second pressure plate, which is in contact with the first pressure plate, is detachably fixedly connected below the first pressure plate. Steel needles of different diameters are fixedly arranged on the bottom surfaces of the first and second pressure plates, respectively. A first groove for accommodating the corresponding steel needles is formed on the top surface of the second pressure plate. A support plate is provided on the base plate, and the support plate is supported and raised / lowered by a lifting device.
[0006] In use, the steel needles on the first and second pressure plates have different diameters, thus allowing for the creation of holes of different diameters, increasing its applicability. The first groove accommodates the steel needles on the first pressure plate, ensuring a close fit between the first and second pressure plates for better compression. During compression, when drilling is required on the second pressure plate, the support plate remains stationary, and the electric telescopic rod extends, moving the corresponding first and second pressure plates downwards to achieve drilling. When drilling is required on the steel needles on the first pressure plate, the second pressure plate is first removed from the first pressure plate, exposing the steel needles on the second pressure plate. Then, a lifting device moves the support plate upwards to the corresponding height, ensuring proper drilling and thus achieving the desired drilling result.
[0007] Preferably, a third pressure plate is provided above the first pressure plate. The steel needles on the first and second pressure plates are distributed in a rectangular array, while the steel needles on the third pressure plate are distributed in a circular array. A second groove is formed on the first pressure plate to accommodate the steel needles on the third pressure plate. The first and third pressure plates are fitted together and detachably fixedly connected. Because the steel needles on the third pressure plate are distributed in a circular array, different styles of needle holes can be achieved, thereby further increasing the range of applications of the equipment.
[0008] Preferably, the bottom surfaces of the first and third pressure plates are provided with slots facing upwards. The top surfaces of the first and second clamping plates are fixedly provided with locking blocks that can engage with the corresponding slots. The sides of the third and first clamping plates are provided with screw holes, and the locking blocks are provided with blind holes corresponding to the screw holes. The locking blocks and slots are fixedly connected by bolts. The locking blocks are inserted into the slots and fixed by bolts, achieving a detachable connection between the first, second, and third pressure plates. The slots being inserted into the locking blocks ensure better fit between the first, second, and third pressure plates, resulting in better drilling.
[0009] Preferably, the lifting device includes side plates vertically connected to both sides of the base plate. The side plates are provided with slide rails along their height direction, and sliders are fitted onto the slide rails. The sliders are fixedly connected to each other via a support plate. One end of a lead screw is rotatably connected to the support plate, and the other end of the lead screw passes through the base plate and is threaded into it. Rotating the lead screw causes its upper end to move upwards, thereby moving the support plate upwards.
[0010] Preferably, the bottom surface of the support plate is fixedly provided with a tapered plate that is wider at the top and narrower at the bottom. A circular hole is formed in the bottom surface of the tapered plate, and a circular rod is rotatably connected to the hole via a bearing. The circular rod is coaxial with and fixedly connected to the lead screw. The tapered plate ensures that the force on the support plate is concentrated at the circular rod, while the circular rod is rotatably connected to the tapered plate via the bearing and fixedly connected to the lead screw, ensuring the rotatable connection between the lead screw and the support plate.
[0011] Preferably, the support plate includes an upper plate, a middle plate, and a lower plate. The lower plate is fixedly connected to the slider. The top surfaces of the upper plate, middle plate, and lower plate are provided with honeycomb holes corresponding to the steel needles on the third pressure plate, the first pressure plate, and the second pressure plate, respectively. Insert rods are fixedly provided on the bottom surfaces of the upper plate and the middle plate. Insert holes corresponding to the insert rods are provided on the top surfaces of the middle plate and the lower plate, thereby enabling better drilling. The insertion rods and insert holes can limit the upper plate and the middle plate, ensuring that they will not be misaligned laterally, thus achieving better drilling.
[0012] The beneficial effects of this utility model are as follows: Since the steel needles on the first pressure plate, the second pressure plate and the third pressure plate are different in terms of direction or layout, different diameters or different styles of needle holes can be provided, thereby increasing the applicability of this device.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] A perforation device for desiccant bags, such as Figure 1 and Figure 2 As shown. It includes a base plate 1, which is supported by columns. A vertical plate 2 is vertically connected to one side of the base plate 1. A horizontal plate 3 is vertically connected to the upper end of the vertical plate 2. One end of an electric telescopic rod 4 is fixedly connected to the bottom surface of the horizontal plate 3. The other end of the electric telescopic rod 4 is fixedly connected to a first pressure plate 5. A second pressure plate 6, which is in contact with the first pressure plate 5, is detachably fixedly connected to the bottom of the first pressure plate 5. Steel needles 8 of different diameters are fixedly installed on the bottom surfaces of the first pressure plate 5 and the second pressure plate 6, respectively. A first groove 9 that can accommodate the corresponding steel needles 8 is opened on the top surface of the second pressure plate 6. A support plate 15 is provided on the base plate 1. The support plate 15 is supported and raised by a lifting device.
[0020] In use, the steel needles 8 on the first pressure plate 5 and the second pressure plate 6 have different diameters, thus allowing for the creation of holes of different diameters and increasing its applicability. The first groove 9 accommodates the steel needles 8 on the first pressure plate 5, ensuring a close fit between the first pressure plate 5 and the second pressure plate 6 for better compression. During compression, when drilling is required on the second pressure plate 6, the support plate 15 remains stationary, and the electric telescopic rod 4 extends, causing the corresponding first and second pressure plates 5 and 6 to move downwards to achieve drilling. When drilling is required on the steel needles 8 on the first pressure plate 5, the second pressure plate 6 is first removed from the first pressure plate 5, exposing the steel needles 8 on the second pressure plate 6. Then, a lifting device is used to move the support plate 15 upwards to the corresponding height, ensuring normal drilling and thus achieving the desired drilling effect.
[0021] A third pressure plate 7 is provided above the first pressure plate 5. The steel needles 8 on the first and second pressure plates 5 are distributed in a rectangular array, while the steel needles 8 on the third pressure plate 7 are distributed in a circular array. A second groove 9 is provided on the first pressure plate 5 to accommodate the steel needles 8 on the third pressure plate 7. The first pressure plate 5 and the third pressure plate 7 are fitted together and detachably fixedly connected. Because the steel needles 8 on the third pressure plate 7 are distributed in a circular array, different styles of needle holes can be achieved, thereby further increasing the range of applications for the equipment.
[0022] The first pressure plate 5 and the third pressure plate 7 have slots 10 formed around their bottom edges. The top surfaces of the first and second clamping plates are fixedly provided with locking blocks 11 that can engage with the corresponding slots 10. The third clamping plate and the first clamping plate have screw holes on their sides. The locking blocks 11 have blind holes corresponding to the screw holes. The locking blocks 11 and the slots 10 are fixedly connected by bolts 12. The insertion of the locking blocks 11 into the slots 10 and their fixed connection by bolts 12 enables a detachable connection between the first pressure plate 5, the second pressure plate 6, and the third pressure plate 7. The insertion of the slots 10 into the locking blocks 11 ensures a better fit between the first pressure plate 5, the second pressure plate 6, and the third pressure plate 7, resulting in better drilling.
[0023] The lifting device includes side plates 13 vertically connected to both sides of the base plate 1. A slide rail 14 is provided along the height direction of each side plate 13, and a slider is fitted onto the slide rail 14. The sliders are fixedly connected to each other via a support plate 15. A tapered plate 18, wider at the top and narrower at the bottom, is fixedly mounted on the bottom surface of the support plate 15. A circular hole is formed on the bottom surface of the tapered plate 18, and a circular rod 17 is rotatably connected to the hole via a bearing. The circular rod 17 is coaxial with and fixedly connected to a lead screw 16. The lower end of the lead screw 16 passes through the base plate 1 and is threaded into it. Rotating the lead screw 16 causes its upper end to move upward, thereby moving the support plate 15 upward. The tapered plate 18 ensures that the force on the support plate 15 is concentrated on the circular rod 17. The circular rod 17 is rotatably connected to the tapered plate 18 via a bearing and is fixedly connected to the lead screw 16, ensuring the rotatable connection between the lead screw 16 and the support plate 15.
[0024] A rotating handle is provided at the lower end of the lead screw 16 to facilitate its rotation.
[0025] To achieve better opening effect, the support plate may include an upper plate, a middle plate, and a lower plate, with the lower plate fixedly connected to the slider. The top surfaces of the upper plate, middle plate, and lower plate are sequentially provided with honeycomb holes corresponding to the steel needles on the third pressure plate 7, the first pressure plate 5, and the second pressure plate 6. The bottom surfaces of the upper plate and middle plate are fixedly provided with insertion rods, and the top surfaces of the middle plate and lower plate are provided with insertion holes corresponding to the insertion rods.
[0026] The use of this application allows for the provision of needle holes of different diameters or styles, as the steel needles 8 on the first pressure plate 5, the second pressure plate 6, and the third pressure plate 7 differ in their orientation or layout. This increases the applicability of the device.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
