Description

Technical Field

[0001] This utility model relates to the technical field of desiccant production equipment, specifically to a desiccant packaging bag perforation device. Background Technology

[0002] Desiccants are substances that can remove moisture from damp materials, such as calcium sulfate and calcium chloride. They dry by combining with water to form hydrates. The use of desiccants in food packaging is to prevent excess moisture from causing food spoilage. Current desiccant food packaging paper is often a sealed structure, but its water and air permeability is poor, resulting in poor drying effect. Alternatively, to achieve a better drying effect, holes are punched in the desiccant packaging material with a needle to allow air to pass between the inside of the desiccant and the outside.

[0003] During the punching process, different desiccants require different vent holes, but the size of the punching needles in existing punching equipment is fixed, which cannot meet the needs of actual production. To solve this technical problem, the existing technology CN212919694U provides a desiccant packaging bag punching device. By placing the desiccant packaging bag to be punched on the operating table, a cylinder drives a slider to move vertically along the guide rail, and the punching needles on the mounting plate punch the desiccant packaging bag. During the punching process, different sized punching needles can be replaced according to the required hole diameter, which can effectively improve the flexibility of the punching device, as well as the efficiency and quality of punching.

[0004] However, certain technical issues may arise during its use. For example, when operating the device, if the size of the perforations on the desiccant packaging bag needs to be changed, the original needles fixed by the magnetic sleeve in the installation cavity must first be removed. Then, a needle conforming to the new hole diameter requirements is inserted into the installation cavity and positioned using the magnetic sleeve. However, because the inner diameter of the magnetic sleeve is constant, a gap may exist between the needle and the inner wall of the magnetic sleeve after installation, resulting in insecure fixing and affecting the stability of the needles during device operation. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a desiccant bag piercing device that not only facilitates workers in piercing desiccant bags on the operating table but also allows workers to easily replace the device with piercing needles of different diameters to adjust the size of the piercing holes on the desiccant bags. Furthermore, it improves the stability of the piercing needles during use.

[0006] This utility model is achieved through the following technical solution: a device for puncturing desiccant packaging bags is provided, including a main frame and an operating table and mounting base installed on the top of the main frame. A cylinder is fixed to the mounting base above the operating table. A connecting rod fixed to the end of the cylinder's output shaft is provided between the cylinder and the operating table. A mounting plate is fixedly connected to the bottom of the connecting rod. A fixing plate is fixedly connected to the bottom of the mounting plate. An installation groove is formed on the top of the fixing plate. An installation sleeve is provided at the bottom of the fixing plate. The installation sleeve extends vertically upward through the fixing plate into the installation groove. The installation sleeve and the fixing plate... The mounting sleeve is rotatably connected to the mounting plate. A worm gear, meshing with the worm gear on the mounting sleeve, is provided on the outer wall of the mounting sleeve. Threaded rods, rotatably connected to the bottom of the mounting plate, are coaxially fixed to the left and right side walls of the worm gear. The threads of the two threaded rods have opposite directions. A movable block, fitting against the bottom of the mounting plate, is fitted onto the threaded rod. A clamping plate, located between the mounting sleeve and the mounting plate, is fixed to the movable block. The lateral distance between the two clamping plates forms a needle clamping and fixing space. A needle, abutting against the inner sidewalls of the two clamping plates, is provided within this space.

[0007] In use, this utility model comprises a main frame and an operating table and mounting base mounted on top of the main frame. A cylinder, fixed to the mounting base, is positioned above the operating table. A connecting rod, fixed to the end of the cylinder's output shaft, is positioned between the cylinder and the operating table. A mounting plate is fixedly connected to the bottom of the connecting rod, and a fixing plate is fixedly connected to the bottom of the mounting plate. A mounting groove is formed on the top of the fixing plate, and a mounting sleeve is positioned at the bottom of the fixing plate. The mounting sleeve extends vertically upwards, passing through the fixing plate into the mounting groove. The mounting sleeve is rotatably connected to the fixing plate. A worm gear, meshing with the worm gear on the mounting sleeve, is positioned in the mounting groove. Threaded rods, rotatably connected to the bottom of the mounting plate, are coaxially fixed to the left and right side walls of the worm gear. The threads of the two threaded rods... Conversely, a movable block is fitted onto the threaded rod, fitting snugly against the bottom of the mounting plate. A clamping plate is fixedly connected to the movable block between the mounting sleeve and the mounting plate. The lateral distance between the two clamping plates forms a needle-holding and fixing space. A needle is installed within this space, abutting against the inner walls of the two clamping plates. In use, the desiccant bag is first placed on the operating table. Then, the cylinder on the mounting base is opened, extending its output shaft. This, via the connecting rod, drives the mounting plate downwards, causing the needle, fixing plate, and mounting sleeve to move downwards with the mounting plate. This allows the needle to pierce the desiccant bag on the operating table. To adjust the hole size, the operator rotates the mounting sleeve at the bottom of the fixing plate clockwise. The rotation of the screw thread on the outer wall of the mounting sleeve causes the worm gear meshing with it to rotate within the mounting groove. Because the movable blocks are in contact with the bottom of the mounting plate and the threads of the two threaded rods rotate in opposite directions, the two movable blocks do not rotate separately with the two threaded rods. Instead, they move towards each other under the rotational drive of the two threaded rods, and each moves the clamping plates fixed to them. This prevents the clamping plates from contacting the needle, making it easier for workers to remove the needle from the needle clamping space and the mounting sleeve. Then, a new needle of a different diameter is inserted into the needle clamping space and the mounting sleeve, with the tip of the needle in contact with the bottom of the mounting plate and the tip pointing downwards. Finally, the bottom of the mounting plate is then... The sleeve rotates in the opposite direction, causing the worm gear on the outer wall of the sleeve to rotate within the mounting groove. This drives the worm wheel meshing with the sleeve to rotate within the mounting groove, and the threaded rod rotates along with the worm wheel. Because the movable blocks are in contact with the bottom of the mounting plate, and the threads of the two threaded rods rotate in opposite directions, the two movable blocks do not rotate separately with the two threaded rods. Instead, they move towards each other under the rotational drive of the two threaded rods, and each moves the clamping plates fixed to them, thus re-engaging the clamping plates with the puncture needles. This not only facilitates the operator in puncturing the desiccant bags on the operating table, but also allows the operator to easily replace the device with puncture needles of different diameters, thereby adjusting the size of the puncture holes in the desiccant bags.It can also improve the stability of needle insertion during use.

[0008] Preferably, several mounting sleeves are provided at the bottom of the fixing plate. By providing several mounting sleeves at the bottom of the fixing plate, it is convenient for workers to puncture the desiccant packaging bags on the operating table.

[0009] Preferably, the mounting plate is a magnetic plate. By using a magnetic plate, the magnetic force of the plate can fix the needle to the mounting plate, making it convenient for workers to change needles of different diameters.

[0010] Preferably, a mounting sleeve is fixedly connected to the end of the cylinder output shaft. A spring, also fixedly connected to the end of the cylinder output shaft, is installed inside the mounting sleeve. The connecting rod extends into the mounting sleeve and is fixedly connected to the bottom of the spring. The outer wall of the connecting rod is flush with the inner wall of the mounting sleeve. By fixing the mounting sleeve to the end of the cylinder output shaft, installing a spring inside the mounting sleeve, and extending the connecting rod into the mounting sleeve and fixing it to the bottom of the spring, with the outer wall of the connecting rod flush with the inner wall of the mounting sleeve, the connecting rod can extend and retract within the mounting sleeve when the needle punctures the desiccant packaging bag during use. This buffers the needle and prevents damage to it.

[0011] Preferably, a rubber pad is fixed to the inner wall of the clamp. By fixing the rubber pad to the inner wall of the clamp, the stability of the device during needle insertion can be improved.

[0012] The beneficial effects of this utility model are as follows: A main frame is provided, along with an operating table and mounting base installed on top of the main frame. A cylinder is fixed to the mounting base above the operating table. A connecting rod, fixed to the end of the cylinder's output shaft, is provided between the cylinder and the operating table. A mounting plate is fixedly connected to the bottom of the connecting rod, and a fixing plate is fixedly connected to the bottom of the mounting plate. A mounting groove is provided on the top of the fixing plate, and a mounting sleeve is provided at the bottom of the fixing plate. The mounting sleeve extends vertically upwards, passing through the fixing plate into the mounting groove. The mounting sleeve is rotatably connected to the fixing plate. A worm gear, meshing with the worm gear on the mounting sleeve, is provided in the mounting groove on the outer wall of the mounting sleeve. Threaded rods, rotatably connected to the bottom of the mounting plate, are coaxially fixed to the left and right side walls of the worm gear. The threads of the two threaded rods... Conversely, a movable block is fitted onto the threaded rod, fitting snugly against the bottom of the mounting plate. A clamping plate is fixedly connected to the movable block between the mounting sleeve and the mounting plate. The lateral distance between the two clamping plates forms a needle-holding and fixing space. A needle is installed within this space, abutting against the inner walls of the two clamping plates. In use, the desiccant bag is first placed on the operating table. Then, the cylinder on the mounting base is opened, extending its output shaft. This, via the connecting rod, drives the mounting plate downwards, causing the needle, fixing plate, and mounting sleeve to move downwards with the mounting plate. This allows the needle to pierce the desiccant bag on the operating table. To adjust the hole size, the operator rotates the mounting sleeve at the bottom of the fixing plate clockwise. The rotation of the screw thread causes the worm gear on the outer wall of the mounting sleeve to rotate within the mounting groove, which in turn drives the worm wheel to rotate within the groove. This causes the threaded rod to rotate along with the worm wheel. Because the movable blocks are in contact with the bottom of the mounting plate, and the threads of the two threaded rods have opposite directions, the two movable blocks do not rotate separately with the two threaded rods. Instead, they move towards each other under the rotational drive of the two threaded rods, moving the clamping plates fixed to them. This prevents the clamping plates from contacting the needle, allowing the worker to easily remove the needle from the needle clamping space and mounting sleeve. Then, a new needle of a different diameter is inserted into the needle clamping space and mounting sleeve, ensuring the top of the needle is in contact with the bottom of the mounting plate. With the tip pointing downwards, the mounting sleeve at the bottom of the fixed plate is then rotated in the opposite direction. This causes the worm gear on the outer wall of the mounting sleeve to rotate within the mounting groove, thereby driving the worm wheel meshing with it to rotate within the mounting groove. Because the movable blocks are in contact with the bottom of the mounting plate and the threads of the two threaded rods rotate in opposite directions, the two movable blocks do not rotate separately with the two threaded rods. Instead, they move towards each other under the rotational drive of the two threaded rods, and each moves the clamping plates fixed to them, thus causing the two clamping plates to re-engage with the puncture needle. This not only facilitates the operator in puncturing the desiccant bags on the operating table but also allows the operator to easily replace the device with puncture needles of different diameters, thereby adjusting the size of the puncture holes on the desiccant bags.It can also improve the stability of needle insertion during use.

[0021] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0022] like Figures 1-6The present invention discloses a desiccant packaging bag puncture device, comprising a main frame 3 and an operating platform 2 and a mounting base 1 mounted on the top of the main frame 3. A cylinder 4 is fixed to the mounting base 1 above the operating platform 2. A connecting rod 10, fixed to the end of the output shaft of the cylinder 4, is provided between the cylinder 4 and the operating platform 2. A mounting plate 9 is fixedly connected to the bottom of the connecting rod 10. A fixing plate 6 is fixedly connected to the bottom of the mounting plate 9. A mounting groove 12 is formed on the top of the fixing plate 6. A mounting sleeve 7 is provided at the bottom of the fixing plate 6. The mounting sleeve 7 extends vertically upward through the fixing plate 6 into the mounting groove 12. The mounting sleeve 7 is rotatably connected to the fixing plate 6. The outer wall of the sleeve 7 is provided with a worm gear 16 located in the mounting groove 12. The mounting groove 12 is provided with a worm wheel 14 that meshes with the worm gear 16 on the mounting sleeve 7. The left and right side walls of the worm wheel 14 are coaxially fixed with threaded rods 17 that are rotatably connected to the bottom of the mounting plate 9. The threads of the two threaded rods 17 have opposite directions. The threaded rods 17 are fitted with movable blocks 15 that fit against the bottom of the mounting plate 9. The movable blocks 15 are fixed with clamping plates 19 located between the mounting sleeve 7 and the mounting plate 9. The lateral distance between the two clamping plates 19 forms a needle clamping and fixing space. The needle clamping and fixing space is provided with needles 8 that abut against the inner side walls of the two clamping plates 19.

[0023] By installing several mounting sleeves 7 at the bottom of the fixed plate 6, it is convenient for workers to puncture the desiccant packaging bags on the operating table 2. By setting the mounting plate 9 as a magnetic plate, the magnetic force of the magnetic plate can fix the puncture needle 8 to the mounting plate 9, making it convenient for workers to change puncture needles 8 of different diameters. By fixing the mounting sleeve 5 to the end of the output shaft of the cylinder 4, and installing a spring 11 fixed to the end of the output shaft of the cylinder 4 inside the mounting sleeve 5, the connecting rod 10 extends into the mounting sleeve 5 and is fixed to the bottom of the spring 11. The outer side wall of the connecting rod 10 is fitted against the inner side wall of the mounting sleeve 5. When the device is in use, after the puncture needle 8 punctures the desiccant packaging bag, the connecting rod 10 can extend and retract within the mounting sleeve 5, thereby buffering the puncture needle 8 and preventing damage to the puncture needle 8. By fixing a rubber pad 18 to the inner side wall of the clamping plate 19, the stability of the puncture needle 8 can be improved during use. By providing a connecting plate 13 fixed to the bottom of the mounting plate 9 on the side of the threaded rod 17 away from the worm gear 14, and having the end of the threaded rod 17 away from the worm gear 14 inserted into the connecting plate 13 and rotatably connected to the bottom of the mounting plate 9, the stability of the threaded rod 17 during use can be improved.

[0024] Combined with appendix Figure 1-6The method of using this utility model is as follows: First, the desiccant packaging bag needs to be placed on the operating table 2. Then, the cylinder 4 on the control mounting base 1 is opened, causing the output shaft of the cylinder 4 to extend. This, through the transmission of the connecting rod 10, drives the magnetic plate to move downward, thereby causing the piercing needle 8, the fixing plate 6, and the mounting sleeve 7 to move downward with the magnetic plate. This allows the piercing needle 8 to pierce the desiccant packaging bag on the operating table 2. After the piercing needle 8 pierces the desiccant packaging bag, the mounting sleeve 5, driven by the cylinder 4, moves downward on the connecting rod 10, compressing the spring 11 inside the mounting sleeve 5. This buffers the needle 8, preventing damage. If the operator wants to adjust the hole size, they rotate the mounting sleeve 7 at the bottom of the fixing plate 6 clockwise. This causes the worm gear 16 on the outer wall of the mounting sleeve 7 to rotate within the mounting groove 12, driving the meshing worm wheel 14 to rotate within the mounting groove 12. The threaded rod 17 then rotates with the worm wheel 14 on the connecting plate 13. Because the movable block 15 is in contact with the bottom of the magnetic plate, and the threads of the two threaded rods 17 have opposite directions, the two movable blocks 15 will not rotate separately with the two threaded rods 17. Driven by the rotation of the two threaded rods 17, they move towards each other, and respectively drive the clamping plates 19 fixed to them to move, so that the rubber pads 18 on the two clamping plates 19 no longer abut against the needles 8, thus making it easier for the staff to remove the needles 8 from the needle clamping space and the mounting sleeve 7. Then, a new needle 8 of a different diameter is placed into the needle clamping space and the mounting sleeve 7, and the top of the needle 8 is made to fit against the bottom of the magnetic plate, so that the needle 8 is attracted and fixed to the magnetic plate, with the tip of the needle 8 pointing downwards. Then, by rotating the mounting sleeve 7 at the bottom of the fixing plate 6 in the opposite direction, it is moved to... The worm gear 16 on the outer wall of the movable mounting sleeve 7 rotates in the mounting groove 12, thereby driving the worm wheel 14 meshing with it to rotate in the mounting groove 12, and causing the threaded rod 17 to rotate on the connecting plate 13 along with the worm wheel 14. At this time, because the movable block 15 is in contact with the bottom of the magnetic plate and the threads of the two threaded rods 17 are opposite, the two movable blocks 15 will not rotate with the two threaded rods 17 respectively, but will move towards each other under the rotation drive of the two threaded rods 17, and respectively drive the clamping plate 19 fixed to it to move, so that the rubber pads 18 on the two clamping plates 19 are re-abutted against the needle 8.

[0025] Of course, the above description is not limited to the examples above.
