Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and more specifically, to a precise positioning cardboard box creasing mechanism. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and there are various specifications and models. Cardboard boxes commonly use three-layer and five-layer, while seven-layer is less common. The color and feel of different types of paper are different, and the paper produced by different manufacturers is also different. In the cardboard box production process, creasing is an important process. Creases can make the cardboard box more regular and convenient when folding and forming.

[0003] The position of the creasing plate on the pressure plate in the existing mechanism is fixed and cannot be adjusted, which means that the device can only creasing cardboard of a fixed size, thus limiting the applicability of the device.

[0004] A search revealed that Chinese patent CN220904244U discloses a cardboard creasing mechanism. This structure allows the position of the creasing plate to be adjusted according to the size of the cardboard. By loosening the first fixing bolt, the movable rod is driven to move along the guide rod. The movement of the movable rod causes the creasing plate to move. After the creasing plate is adjusted to the corresponding position, the first fixing bolt is tightened to fix the movable rod. The position of the creasing plate is easy to adjust, thus enabling the device to creasing cardboard of different sizes, effectively expanding the application range of the device.

[0005] However, in actual use, this structure only places the cardboard on the base plate during the creasing process without effectively fixing the cardboard. The cardboard may move when subjected to the pressure of the creasing plate, resulting in inaccurate creasing position and creasing effect, which affects the quality of the carton and its subsequent use. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a precise positioning carton creasing mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A precise positioning carton creasing mechanism includes a base plate, a support frame fixedly mounted on the top of the base plate, a plurality of first electric telescopic rods fixedly mounted on one side of the support frame, a fixed frame fixedly mounted on the output end of the first electric telescopic rods, and a positioning mechanism provided on one side of the fixed frame.

[0009] The positioning mechanism includes guide frames fixedly installed on both sides of the fixed frame, U-shaped rods fixedly installed on both sides of the support frame, the guide frames and U-shaped rods being slidably connected, a fixed frame being fixedly installed at one end of the U-shaped rod, and a central baffle being fixedly installed on one side of the fixed frame;

[0010] The surface of the fixed frame is provided with a sliding groove, and multiple T-shaped sliders are slidably arranged inside the sliding groove. A side clamp is fixedly provided at one end of the T-shaped slider, and a guide groove is provided on the surface of the side clamp. The fixed frame is slidably connected to the guide groove.

[0011] A first stepper motor is fixedly installed on one side of the fixed frame. A bidirectional threaded rod is fixedly provided at the output end of the first stepper motor. A threaded hole is opened on the surface of the T-shaped slider. The bidirectional threaded rod matches the threaded groove.

[0012] By adopting the above technical solution, multiple positioning methods are combined to clamp the sides of the carton with the side clamps, and the center baffle and the fixed frame clamp the front and back of the carton, achieving precise positioning and flexibly adapting to the positioning of cartons of different sizes, thus improving the versatility of the mechanism.

[0013] As a further description of the above technical solution: a pressure applying mechanism is provided on one side of the support frame, the pressure applying mechanism includes a top frame fixedly installed on one side of the support frame, a second stepper motor is fixedly installed on the other side of the support frame, a screw is fixedly installed at the output end of the second stepper motor, and an internal thread sleeve is connected to the external thread of the screw, the internal thread sleeve is slidably connected to the top frame;

[0014] An electric push rod is fixedly installed at the bottom of the internal threaded sleeve, a support plate is fixedly installed at the output end of the electric push rod, and a protrusion is fixedly installed at the bottom of the support plate.

[0015] By adopting the above technical solution, the position can be precisely adjusted, and the support plate can be accurately adjusted to the appropriate position above the carton. Moreover, the electric push rod can further flexibly adjust the height of the support plate and the protrusion, thereby controlling the indentation force and depth to meet different indentation requirements.

[0016] As a further description of the above technical solution: a second electric telescopic rod is fixedly installed around the protrusion, an indentation plate is fixedly installed at the output end of the second electric telescopic rod, a stabilizing block is fixedly installed at the top of the indentation plate, a plurality of fixing grooves are opened on the surface of the support plate, a stabilizing rod is fixedly installed inside the fixing groove, and one end of the stabilizing rod passes through the stabilizing block and extends to the outside of the stabilizing block.

[0017] The bottom of the indentation plate is provided with a connecting groove, and a connecting block is inserted into the connecting groove. An indentation head is fixedly provided at one end of the connecting block, and the indentation plate and the connecting block are connected by bolts.

[0018] By adopting the above technical solution, the creasing position can be adjusted flexibly, and the position of the creasing plate can be precisely adjusted according to the actual situation of the carton to achieve multi-position creasing, improve the adaptability of creasing, and facilitate quick and easy replacement of the creasing head, reducing maintenance difficulty and cost, which is conducive to extending the service life of the equipment and ensuring the continuous and efficient operation of creasing work.

[0019] The technical effects and advantages of this utility model are as follows:

[0020] 1.

Then, the first stepper motor drives the bidirectional threaded rod to make the two side clamps move towards each other to clamp the carton. Multiple positioning methods ensure the accuracy of the carton's position. Moreover, the guide frame and the U-shaped rod are slidably connected to restrict the movement direction of the fixed frame. The guide groove on the side clamp is slidably connected to the fixed frame to ensure the stability of the side clamp movement and avoid deviation that affects the positioning effect. In this way, it can adapt to the positioning needs of cartons of different sizes, improve the versatility and flexibility of the mechanism, enhance the stability and reliability of the mechanism, ensure the smooth progress of the creasing work, and improve work efficiency and creasing quality.

[0021] 2. By setting up a pressure-applying mechanism, compared with existing technologies, the second stepper motor drives the screw to rotate, causing the internal threaded sleeve to move along the screw and the direction is restricted by the top frame. This allows for precise adjustment of the support plate to be directly above the carton, meeting the creasing requirements of cartons of different heights. Moreover, when the second electric telescopic rod pushes the creasing plate to move, the stabilizing block slides along the stabilizing rod, ensuring stable movement of the creasing plate and avoiding shaking that affects the creasing effect, thus improving creasing accuracy. Furthermore, the electric push rod can further adjust the position of the protrusion, creasing plate, and creasing head, enabling flexible control of parameters such as creasing depth to adapt to diverse creasing requirements. At the same time, the creasing plate and connecting block are connected by plug-in and bolt connections, facilitating quick and easy replacement of the creasing head and reducing maintenance costs.

[0028] 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 protection scope of the present utility model.

[0029] The embodiments disclosed in this application are as follows: Figure 1-5 The carton creasing mechanism shown includes a base plate 1, a support frame 2 fixedly mounted on the top of the base plate 1, a plurality of first electric telescopic rods 3 fixedly mounted on one side of the support frame 2, a fixed frame 4 fixedly mounted on the output end of the first electric telescopic rods 3, and a positioning mechanism mounted on one side of the fixed frame 4.

[0030] The positioning mechanism includes guide frames 5 fixedly installed on both sides of the fixed frame 4, and U-shaped rods 6 fixedly installed on both sides of the support frame 2. The guide frames 5 and U-shaped rods 6 are slidably connected. A fixed frame 7 is fixedly installed at one end of the U-shaped rod 6, and a central baffle 8 is fixedly installed on one side of the fixed frame 7.

[0031] The surface of the fixed frame 4 is provided with a sliding groove, and multiple T-shaped sliders 9 are slidably arranged inside the sliding groove. One end of the T-shaped slider 9 is fixedly provided with a side clamping plate 10, and the surface of the side clamping plate 10 is provided with a guide groove. The fixed frame 7 is slidably connected to the guide groove.

[0032] A first stepper motor 11 is fixedly installed on one side of the fixed frame 4. A bidirectional threaded rod 12 is fixedly provided at the output end of the first stepper motor 11. A threaded hole is opened on the surface of the T-shaped slider 9. The bidirectional threaded rod 12 matches the threaded groove.

[0033] Place the cardboard box to be crimped in a suitable position on the base plate 1, then start the first electric telescopic rod 3. The output end of the first electric telescopic rod 3 pushes the fixed frame 4 to move towards the cardboard box until it contacts one side of the cardboard box, clamping the cardboard box between the central baffle 8 and the fixed frame 4. Since the guide frame 5 and the U-shaped rod 6 are slidably connected, the movement of the fixed frame 4 is guided and restricted, ensuring the accuracy of its movement direction.

[0034] Then, the first stepper motor 11 is started. The output end of the first stepper motor 11 drives the bidirectional threaded rod 12 to rotate. Because the threaded hole on the surface of the T-shaped slider 9 matches the bidirectional threaded rod 12, when the bidirectional threaded rod 12 rotates, under the action of its bidirectional thread, the two T-shaped sliders 9 can move towards or away from each other at the same time. The T-shaped slider 9 slides in the groove on the surface of the fixed frame 4. The side clamping plate 10 at one end of the T-shaped slider 9 moves with the sliding of the T-shaped slider 9. The guide groove on the side clamping plate 10 is slidably connected to the fixed frame 7, which further ensures the stability of the movement of the side clamping plate 10. By adjusting the rotation of the first stepper motor 11, the side clamping plates 10 on both sides clamp the carton between the two side clamping plates 10, thereby achieving precise positioning of the carton.

[0035] Reference Figure 2-3 As shown, a pressure-applying mechanism is provided on one side of the support frame 2. The pressure-applying mechanism includes a top frame 13 fixedly installed on one side of the support frame 2. A second stepper motor 14 is fixedly installed on the other side of the support frame 2. A screw 15 is fixedly installed at the output end of the second stepper motor 14. An internal threaded sleeve 16 is connected to the external thread of the screw 15. The internal threaded sleeve 16 is slidably connected to the top frame 13.

[0036] An electric push rod 17 is fixedly installed at the bottom of the internal threaded sleeve 16, a support plate 18 is fixedly installed at the output end of the electric push rod 17, and a protrusion 19 is fixedly installed at the bottom of the support plate 18.

[0037] Start the second stepper motor 14. The output end of the second stepper motor 14 drives the screw 15 to rotate. The internal threaded sleeve 16, which is threaded to the screw 15, moves along the screw 15 under the rotation of the screw 15. At the same time, the internal threaded sleeve 16 is slidably connected to the top frame 13, which restricts the movement direction of the internal threaded sleeve 16, so that it can only move back and forth.

[0038] By controlling the rotation of the second stepper motor 14, the internal threaded sleeve 16 is adjusted to a suitable position, thereby driving the support plate 18 to move directly above the carton.

[0039] Reference Figure 4-5As shown, a second electric telescopic rod 20 is fixedly installed around the protrusion 19. An indentation plate 21 is fixedly installed at the output end of the second electric telescopic rod 20. A stabilizing block 22 is fixedly installed on the top of the indentation plate 21. A plurality of fixing grooves are opened on the surface of the support plate 18. A stabilizing rod 23 is fixedly installed inside the fixing groove. One end of the stabilizing rod 23 passes through the stabilizing block 22 and extends to the outside of the stabilizing block 22.

[0040] The bottom of the indentation plate 21 is provided with a connecting groove, and a connecting block 24 is inserted into the connecting groove. An indentation head 25 is fixedly provided at one end of the connecting block 24. The indentation plate 21 and the connecting block 24 are connected by bolts.

[0041] Start the second electric telescopic rod 20. The output end of the second electric telescopic rod 20 pushes the creasing plate 21 to move towards the carton. The stabilizing block 22 on the top of the creasing plate 21 slides along the stabilizing rod 23 in the fixing groove on the surface of the support plate 18, ensuring the stability of the movement of the creasing plate 21, thereby adjusting the position of the creasing plate 21 according to the actual situation.

[0042] Once the creasing plate 21 is moved to the appropriate position, the electric push rod 17 is activated. The output end of the electric push rod 17 pushes the support plate 18 downward, thereby causing the protrusion 19 at the bottom of the support plate 18 to move closer to the carton. The protrusion 19 causes the creasing plate 21 and the creasing head 25 to move downward, adjusting the distance between the creasing head 25 and the carton until the creasing head 25 contacts the surface of the carton and applies pressure, forming a creasing on the surface of the carton.

[0043] Since a connecting block 24 is inserted into the connecting groove at the bottom of the indentation plate 21, the indentation plate 21 and the connecting block 24 are connected by bolts, which facilitates the replacement and maintenance of the indentation head 25.

[0044] Working principle of this utility model:

[0045] This utility model is a precise positioning cardboard box creasing mechanism. When using the device, the cardboard box to be creasing is placed in a suitable position on the base plate 1. Then, the first electric telescopic rod 3 is activated. The output end of the first electric telescopic rod 3 pushes the fixed frame 4 to move towards the cardboard box until it contacts one side of the cardboard box, clamping the cardboard box between the central baffle 8 and the fixed frame 4. Since the guide frame 5 is slidably connected to the U-shaped rod 6, the movement of the fixed frame 4 is guided and restricted, ensuring the accuracy of its movement direction.

[0046] Then, the first stepper motor 11 is started. The output end of the first stepper motor 11 drives the bidirectional threaded rod 12 to rotate. Because the threaded hole on the surface of the T-shaped slider 9 matches the bidirectional threaded rod 12, when the bidirectional threaded rod 12 rotates, under the action of its bidirectional thread, the two T-shaped sliders 9 can move towards or away from each other at the same time. The T-shaped slider 9 slides in the groove on the surface of the fixed frame 4. The side clamping plate 10 at one end of the T-shaped slider 9 moves with the sliding of the T-shaped slider 9. The guide groove on the side clamping plate 10 is slidably connected to the fixed frame 7, which further ensures the stability of the movement of the side clamping plate 10. By adjusting the rotation of the first stepper motor 11, the side clamping plates 10 on both sides clamp the carton between the two side clamping plates 10, thereby achieving precise positioning of the carton.

[0047] Then the second stepper motor 14 is started. The output end of the second stepper motor 14 drives the screw 15 to rotate. The internal threaded sleeve 16, which is threaded to the screw 15, moves along the screw 15 under the rotation of the screw 15. At the same time, the internal threaded sleeve 16 is slidably connected to the top frame 13, which restricts the direction of movement of the internal threaded sleeve 16, so that it can only move back and forth.

[0048] By controlling the rotation of the second stepper motor 14, the inner threaded sleeve 16 is adjusted to a suitable position, thereby driving the support plate 18 to move directly above the carton.

[0049] Next, the second electric telescopic rod 20 is activated. The output end of the second electric telescopic rod 20 pushes the creasing plate 21 to move towards the carton. The stabilizing block 22 on the top of the creasing plate 21 slides along the stabilizing rod 23 in the fixing groove on the surface of the support plate 18, ensuring the stability of the movement of the creasing plate 21, thereby adjusting the position of the creasing plate 21 according to the actual situation.

[0050] Once the creasing plate 21 is moved to the appropriate position, the electric push rod 17 is activated. The output end of the electric push rod 17 pushes the support plate 18 downward, thereby causing the protrusion 19 at the bottom of the support plate 18 to move closer to the carton. The protrusion 19 causes the creasing plate 21 and the creasing head 25 to move downward, adjusting the distance between the creasing head 25 and the carton until the creasing head 25 contacts the surface of the carton and applies pressure, forming a creasing on the surface of the carton.

[0051] Since a connecting block 24 is inserted into the connecting groove at the bottom of the indentation plate 21, the indentation plate 21 and the connecting block 24 are connected by bolts, which facilitates the replacement and maintenance of the indentation head 25.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
