Description

Technical Field

[0001] This utility model belongs to the technical field of cardboard box packaging sealing equipment, specifically a cardboard box packaging sealing device. Background Technology

[0002] Cardboard box packaging refers to the packaging of products in paper boxes during the circulation process to protect the products, facilitate storage and transportation, and promote sales. Cardboard box packaging is the most widely used packaging method, which is different from wooden box packaging, woven bag packaging, cloth bag packaging, and plastic box packaging. After the fruit is packaged in a cardboard box, the top opening of the cardboard box needs to be sealed with tape.

[0003] Utility model patent CN221520227U discloses a carton packaging sealing device, which solves the problem that existing packaging sealing devices have limited clamping effect on cartons, leading to deviations during the sealing process. It employs an anti-slip clamping plate on a clamping and stabilizing frame, which rotates under the control of its drive end to the same guide line as the L-shaped frame, ensuring the anti-slip clamping plate is relatively parallel to the L-shaped frame. A subsequent drive motor drives a bidirectional screw to rotate, allowing the two screw sleeves to move in opposite directions. This enables stable clamping of cartons of different widths. The electric push rod moves the rubber pad to restrict the left and right position of the carton. The drive motor rotates the threaded rod, which, under the limit setting of the limiting component, adjusts the height of the lifting plate. The electric cylinder moves the pressing plate to flatten the top lifting plate of the carton, thus achieving multi-directional clamping and stabilization of the carton and preventing the top of the carton from being skewed. The above-mentioned patent structure is complex, and the operation of placing and positioning the carton is cumbersome, which indirectly leads to low sealing efficiency and thus affects production efficiency.

Each side of the work box is fixedly connected to a first pressure detector, and each side of the first pressure detector is fixedly connected to a support plate. The surface of the support plate is provided with rollers, and the number of rollers is evenly distributed on the surface of the support plate. An opening is provided on the back of the work box. Sliding grooves are provided on both sides of the bottom of the inner wall of the work box, and a placement plate is slidably connected inside the sliding grooves. The back of the placement plate extends through the opening to the back of the work box. A second electric cylinder is fixedly connected to the bottom of the work box. The output end of the second electric cylinder is fixedly connected to the placement plate through a connecting frame.

A pressure block is fixedly connected to the bottom of the limiting rod by screws.

[0007] The beneficial effects of this utility model are as follows: 1. This utility model employs a series of ingenious designs to achieve precise omnidirectional positioning of the cardboard box. In the left-right direction, a first motor drives a threaded rod to rotate, causing the movable frames, clamps, first pressure detector, support plate, and rollers on both sides to approach each other until the rollers are in contact with the sides of the cardboard box, completing the precise omnidirectional positioning. In the front-back direction, a second motor drives a baffle to rotate to a vertical position, and a second electric cylinder pushes a placement plate to make the back of the cardboard box fit against the inner wall of the working box, while the positioning plate fits against the front of the cardboard box, effectively fixing the cardboard box in the front-back direction. In the vertical direction, as the movable plate moves downward, the pressure block first contacts the top of the cardboard box. As the movable plate continues to move downward, the tension spring is stretched, and the elasticity of the tension spring causes the pressure block to apply downward pressure to the cardboard box, thereby positioning the cardboard box in the vertical direction. This multi-directional, omnidirectional positioning method greatly improves the positioning effect of the cardboard box, ensuring that the cardboard box will not shake or shift during the sealing process. Compared with traditional devices, the positioning efficiency is significantly improved, and this device has the advantages of good positioning effect and high positioning efficiency.

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0012] like Figures 1 to 6 As shown, the carton packaging sealing device of this embodiment includes a working box 1. Both sides of the inner wall of the working box 1 are provided with sliding grooves, and a movable plate 2 is slidably connected inside the sliding grooves. A first electric cylinder 3 is fixedly connected to the top of the working box 1. The output end of the first electric cylinder 3 extends into the interior of the working box 1 and is fixedly connected to the movable plate 2. A movable sealing machine body 4 is fixedly connected to the bottom of the movable plate 2. A drive box 5 is fixedly connected to the bottom of the working box 1. A threaded rod 6 with both positive and negative threads is rotatably connected inside the drive box 5. Movable frames 7 are slidably connected to both sides inside the drive box 5. A first motor 9 is fixedly connected to the right side of the drive box 5. The output end of the first motor 9 is fixedly connected to the threaded rod 6 with both positive and negative threads. The movable frame 7 is threadedly connected to the threaded rod 6 with both positive and negative threads. Openings are provided on both sides of the working box 1. The openings are slidably connected to the movable frame 7. The end of the movable frame 7 away from the threaded rod 6 extends through the opening into the interior of the working box 1 and is fixedly connected to a clamping plate 8. A first pressure detector is fixedly connected to the adjacent side of the clamping plates 8 on both sides. The device 10 has a support plate 11 fixedly connected to one side of each of the two adjacent first pressure detectors 10. Rollers 12 are provided on the surface of the support plate 11. The number of rollers 12 is several and they are evenly distributed on the surface of the support plate 11. An opening is provided on the back of the working box 1. Sliding grooves are provided on both sides of the bottom of the inner wall of the working box 1. A placement plate 13 is slidably connected inside the sliding groove. The back of the placement plate 13 extends through the opening to the back of the working box 1. A second electric cylinder 14 is fixedly connected to the bottom of the working box 1. The output end of the second electric cylinder 14 is fixedly connected to the placement plate 13 through a connecting frame. Fixing blocks 15 are fixedly connected to both sides of the front of the placement plate 13. A baffle 16 is rotatably connected inside the fixing block 15. A second motor 17 is fixedly connected to the right side of the right fixing block 15. The output end of the second motor 17 is fixedly connected to the baffle 16. A second pressure detector 18 is fixedly connected to the back of the baffle 16. A positioning plate 19 is fixedly connected to the back of the second pressure detector 18.

[0013] refer to Figure 1 There are four limit rods 25 slidingly connected inside the movable plate 2. The limit rods 25 are evenly distributed inside the movable plate 2. A tension spring 26 is fixedly connected to the top of the movable plate 2. The end of the tension spring 26 away from the movable plate 2 is fixedly connected to the limit rod 25. A pressure block 27 is fixedly connected to the bottom of the limit rod 25 by screws.

[0014] In this embodiment, by setting up the limiting rod 25, the tension spring 26 and the pressure block 27, when the movable plate 2 moves down, the pressure block 27 first fits against the top of the carton. As the movable plate 2 continues to move down, the tension spring 26 is stretched. Utilizing the elasticity of the tension spring 26, the pressure block 27 applies downward pressure to the carton, thereby positioning the carton in the vertical direction and preventing the carton from shaking in the vertical direction when it is sealed.

[0015] refer to Figure 4 The drive box 5 has a bearing fixedly connected inside, and the outer ring of the bearing is fixedly connected to the drive box 5, while the inner ring of the bearing is fixedly connected to the threaded rod 6. The bearing is also equipped with lubricating oil and a sealed shaft cover.

[0016] In this embodiment, the bearing configuration reduces the friction between the drive box 5 and the threaded rod 6, thereby facilitating the rotation of the threaded rod 6.

[0017] refer to Figure 1 Movable columns 20 are fixedly connected to the front and rear sides of both sides of the work box 1. A support column 21 is provided at the bottom of the work box 1. A groove is provided on the top of the support column 21. The movable column 20 is slidably connected to the groove. The surface of the movable column 20 is provided with positioning holes. There are several positioning holes, which are evenly distributed on the surface of the movable column 20. Bolts 22 are threaded inside the support column 21. The bolts 22 are inserted into the positioning holes. The surface of the bolts 22 is coated with anti-rust paint.

[0018] In this embodiment, the movable column 20, support column 21, groove, positioning port, and bolt 22 are designed so that the operator can move the movable column 20 up and down, thereby moving the work box 1 up and down and adjusting the height of the device. This allows the operator to adjust the height of the device according to their own height, making it easier for the operator to use the device to seal cartons. When the movable column 20 moves to the appropriate height, the operator tightens the bolt 22 so that the bolt 22 is inserted into the positioning port, thereby locking the height of the movable column 20 and thus locking the height of the device.

[0019] refer to Figure 1 The surface of the support column 21 is fixedly connected to the connecting column 23 and the X-shaped reinforcing frame 24 respectively.

[0020] In this embodiment, the connection between the various support columns 21 is improved by setting up the connecting column 23 and the X-shaped reinforcing frame 24, thereby improving the stability of the device.

[0021] refer to Figure 1 Both sides of the work box 1 are provided with observation ports 28. The observation ports 28 are rectangular and a transparent plate 29 is fixedly connected inside the observation ports 28.

[0022] In this embodiment, through the setting of observation port 28 and transparent plate 29, the operator can observe the operating status of each component in the work box 1 through observation port 28 and transparent plate 29. Transparent plate 29 is made of tempered glass, which has the advantages of high hardness and transparency.

[0023] This utility model places the cardboard box on top of the placement plate 13. The top of the placement plate 13 is provided with anti-slip grooves, and there are several anti-slip grooves. The anti-slip grooves are evenly distributed on the top of the placement plate 13. The anti-slip grooves can increase the friction between the placement plate 13 and the cardboard box, thereby preventing the cardboard box from easily sliding on the top of the placement plate 13. Then, according to the width of the cardboard box, the operator adjusts the first motor 9 to rotate, which drives the positive and negative threaded rod 6 to rotate, thereby driving the movable frames 7 on both sides to move closer to each other, thereby driving the clamping plates 8 on both sides, the first pressure detector 10, the support plate 11 and the roller 12 on both sides to move closer to each other, until the rollers 12 on both sides are respectively in contact with the sides of the cardboard box, thereby positioning the cardboard box in the left and right directions. Then, the operator rotates the second motor 17 to rotate the baffle 16 90 degrees, making the baffle 16 vertical. The operator then extends the second electric cylinder 14, moving the placement plate 13 to the back, which in turn moves the carton to the back until the back of the carton is against the back of the inner wall of the work box 1. At this point, the placement plate 13 continues to move to the back until the positioning plate 19 is against the front of the carton. At this point, the carton cannot move forward or backward, thus positioning the carton in the front-back direction. Then, the operator extends the first electric cylinder 3, moving the movable plate 2 downward. When the movable plate 2 moves downward, the pressure block 27 first contacts the top of the carton. As the movable plate 2 continues to move downward, the tension spring 26 is stretched. Utilizing the elasticity of the tension spring 26, the pressure block 27 applies downward pressure to the carton, thereby positioning the carton in the vertical direction and preventing it from shaking when being sealed. The downward movement of the movable plate 2 also causes the movable sealing machine body 4 to move downward. When the movable sealing machine body 4 moves to the appropriate position, the operator seals the carton using the movable sealing machine body 4. During sealing, the carton cannot move forward, backward, left, right, or up and down, thereby improving the sealing accuracy of the movable sealing machine body 4 and thus improving the sealing effect of the device. The first pressure detector 10 detects the pressure between the roller 12 and the cardboard box, and the second pressure detector 18 detects the pressure between the positioning plate 19 and the cardboard box. A PLC controller is installed on the left side of the work box 1. By setting the first pressure detector 10 and the second pressure detector 18, excessive pressure between the roller 12 or the positioning plate 19 and the cardboard box can be avoided, which could damage the cardboard box, or insufficient pressure could lead to poor positioning stability of the cardboard box. The PLC controller can control the circuit in the device. When the operator rotates the threaded rod 6 using the first motor 9 according to the width of the cardboard box, the movable frame 7, clamping plate 8, first pressure detector 10, support plate 11 and roller 12 on both sides move closer to each other, the first pressure detector 10 starts to work. As the roller 12 gradually comes into contact with the sides of the cardboard box, the roller 12 applies pressure to the cardboard box, and the cardboard box also generates a reaction force on the roller 12 and the first pressure detector 10. After sensing this pressure, the first pressure detector 10 converts it into an electrical signal. The electrical signal is transmitted to the PLC controller on the left side of the work box 1. The PLC controller processes and analyzes the signal to determine if the pressure is within the appropriate range. The operator uses the second motor 17 to rotate the baffle 16 to a vertical position, and then uses the second electric cylinder 14 to push the placement plate 13 to move the carton to the back. When the back of the carton is in contact with the back of the inner wall of the work box 1, the placement plate 13 continues to move, and the positioning plate 19 contacts the front of the carton and applies pressure. The second pressure detector 18 senses the pressure between the positioning plate 19 and the carton, converts it into an electrical signal, and transmits it to the PLC controller. After receiving the electrical signals transmitted by the first pressure detector 10 and the second pressure detector 18, the PLC controller will judge according to the preset pressure range. If the pressure is too high, the PLC controller will issue a command to control the first motor 9 or the second electric cylinder 14 to adjust the action, reduce the pressure on the carton, and prevent the carton from being damaged. If the pressure is too low, the PLC controller will control the corresponding motor or electric cylinder to continue to operate, increase the pressure on the carton, and ensure the positioning stability of the carton.

[0024] The first pressure detector 10, the second pressure detector 18, and the PLC controller mentioned above are all common existing technologies and are common knowledge to those skilled in the art. Therefore, this application will not elaborate on them further. The movable sealing machine body 4 mentioned above is similar in principle to the movable sealing machine body 4 mentioned in the utility model patent disclosed in publication (announcement) number: CN221520227U, which discloses a carton packaging sealing device, and achieves the same effect. Therefore, this application will not elaborate on them further.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
