Description

Technical Field

[0001] This utility model relates to the field of fastening equipment technology, specifically a flexible folding and shaping clamp for roll tube packaging boxes. Background Technology

[0002] In the manufacturing of rolled tube packaging boxes, edge folding and shaping is a crucial process, directly impacting the box's appearance, structural strength, and subsequent performance. The performance of the processing fixture, as a key tool ensuring the smooth implementation of this process, plays a decisive role in the entire production process. With the widespread application of rolled tube packaging boxes across various industries, market demands for quality and production efficiency are constantly increasing, placing higher requirements on processing fixtures. Therefore, developing efficient, precise processing fixtures that can adapt to different specifications of rolled tube packaging boxes has become an important direction for industry development.

[0003] Currently, existing jig technology for processing rolled tube packaging boxes has shortcomings. Firstly, regarding clamping synchronization, many jigs struggle to achieve precise, simultaneous clamping from both sides. Since rolled tube packaging boxes require uniform clamping force during the folding and shaping process, asynchronous clamping operations can easily lead to uneven stress on the packaging box, resulting in deformation and affecting product quality consistency. Secondly, the jigs have poor adaptability. Rolled tube packaging boxes of different specifications vary in size and shape, but existing jigs often lack effective flexible clamping structures, making it difficult to adaptively adjust to the actual shape of the packaging box. This can easily damage the packaging box surface during clamping, causing scratches, dents, etc., reducing the product's appearance quality. Utility Model Content

[0004] The purpose of this utility model is to provide a flexible folding and shaping fixture for rolled tube packaging boxes, so as to solve the problems of poor adaptability and insufficient stability of existing rolled tube packaging box processing fixtures mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: The flexible folding and shaping fixture for the rolled tube packaging box includes a U-shaped base for fixing the rolled tube packaging box. The outer walls of the two sides of the U-shaped base are symmetrically equipped with synchronously working servo cylinders. The inner sides of the U-shaped base are symmetrically arranged with a first hollow clamp and a second hollow clamp. Several sets of evenly spaced flexible rebound clamping rods are inserted into the surface of the first hollow clamp and the second hollow clamp on the side that contacts the rolled tube packaging box. Both the first hollow clamp and the second hollow clamp include an outer shell. Inside the outer shell, on the side near the flexible spring clamp, there are guide cylinders that are the same number as the flexible spring clamp, corresponding in position, and of the same size, and are inserted into each other. The end of the flexible spring clamp that contacts the roll tube packaging box is equipped with a hemispherical soft cap, and the end of the flexible spring clamp away from the soft cap is equipped with a flexible return spring.

[0006] Preferably, the piston rods of the two sets of servo cylinders are respectively connected to the ends of the first hollow clamp and the second hollow clamp, which can ensure that the power of the servo cylinder is directly and effectively transmitted to the hollow clamp, making the movement of the clamp more precise and stable, thereby realizing precise clamping and loosening operations on the roll tube packaging box and improving the accuracy of processing.

[0007] Preferably, one end of the flexible spring-loaded clamping rod is inserted into the flexible reset spring, and a limiting plate is installed on the flexible spring-loaded clamping rod to ensure that the flexible spring-loaded clamping rod can smoothly compress the spring and rebound when subjected to force. At the same time, the limiting plate can effectively prevent the clamping rod from falling out, ensuring its stable movement within the guide structure and maintaining the normal working state of the clamp.

[0008] Preferably, the flexible rebound clamp rod is inserted into the flexible reset spring for a length of 5-15cm, which provides sufficient connection length between the clamp rod and the spring, enhances the stability of the connection between the two, and provides a reasonable stroke for the elastic movement of the clamp rod, ensuring the flexible clamping effect.

[0009] Preferably, the inner wall of the outer casing on the side away from the flexible rebound clamp is equipped with a fixing post that is the same number, corresponding in position, and compatible in size as the flexible return spring, and is plugged into it. This can stably install the spring, ensure that the spring is fixed in position during operation, and provide reliable support for the stable rebound of the flexible rebound clamp.

[0010] Preferably, the distance between the fixed post and the end of the flexible rebound clamp is the same as the length of the flexible rebound clamp extending out of the outer shell, so that the compression and reset of the spring and the movement of the clamp are perfectly matched, ensuring that the clamp can work normally in different states.

[0011] Preferably, the end of the flexible rebound clamp is provided with a connecting screw hole, and the soft cap is coaxially connected with a threaded post that is adapted to the size of the connecting screw hole and is threadedly connected. This facilitates the installation and removal of the soft cap, makes it easy to replace and maintain, and ensures the firmness of the connection, so that the soft cap can stably play its role in protecting the packaging box.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: In this flexible folding and shaping fixture for the rolled tube packaging box, the servo cylinders symmetrically installed on the outer walls of both sides of the U-shaped base can precisely control the clamping action of the rolled tube packaging box, ensuring the synchronicity and accuracy of the clamping; the first and second hollow clamps symmetrically arranged on both sides of the U-shaped base provide installation space for the flexible spring-loaded clamping rods, and the symmetrical arrangement ensures the uniform distribution of clamping force; the several sets of evenly spaced flexible spring-loaded clamping rods inserted into the surface of the first and second hollow clamps on the side in contact with the rolled tube packaging box can adapt to the shape of the rolled tube packaging box, achieving flexible clamping and avoiding damage to the packaging box; through the first hollow clamp and the second hollow clamp, the flexible spring-loaded clamping rods can adapt to the shape of the rolled tube packaging box, achieving flexible clamping and avoiding damage to the packaging box; through the first hollow clamp and the second hollow clamp, the flexible spring-loaded clamp ... and the second hollow clamp, the flexible spring-loaded clamp and the second hollow clamp, the flexible spring-loaded clamp and the second hollow clamp, the flexible spring-loaded clamp and the second hollow The guide cylinders installed inside the outer shell of the hollow clamp and the second hollow clamp, near the flexible spring-loaded clamp rods, are the same number, corresponding in position, and of the same size, and are plugged into each other. These guide cylinders guide the movement of the flexible spring-loaded clamp rods, ensuring their stability. The hemispherical soft cap installed at the end of the flexible spring-loaded clamp rod that contacts the roll tube packaging box further increases the softness of the contact with the packaging box and prevents scratches. The flexible return spring installed at the end of the flexible spring-loaded clamp rod away from the soft cap allows the flexible spring-loaded clamp rod to automatically return to its original position after the clamping action is completed, preparing for the next clamping operation. The overall structure works together to achieve effective clamping and stable operation of the flexible folding and shaping of the roll tube packaging box. Attached Figure Description

[0017] Flexible edge-folding and shaping fixtures for rolled tube packaging boxes, such as Figures 1-3As shown, the device includes a U-shaped base 10 for fixing the tube packaging box. Servo cylinders 20 are symmetrically mounted on the outer walls of both sides of the U-shaped base 10, operating synchronously. A first hollow clamp 30 and a second hollow clamp 40 are symmetrically arranged on both sides inside the U-shaped base 10. Several sets of evenly spaced flexible spring-loaded clamping rods 50 are inserted into the surface of the first hollow clamp 30 and the second hollow clamp 40 on the side that contacts the tube packaging box. Both the first hollow clamp 30 and the second hollow clamp 40 include an outer shell 31. Inside the outer shell 31, near the side of the flexible spring-loaded clamping rods 50, a flexible spring-loaded clamping rod is installed. 50 identical, corresponding, and compatible guide cylinders 32 are connected by an interlocking mechanism. A hemispherical soft cap 53 is installed at the end of the flexible rebound clamping rod 50 that contacts the tube packaging box, and a flexible return spring 34 is installed at the end of the flexible rebound clamping rod 50 away from the soft cap 53. The clamping action on the tube packaging box can be precisely controlled by servo cylinders 20 symmetrically installed on the outer walls of both sides of the U-shaped base 10, ensuring the synchronicity and accuracy of the clamping. The flexible rebound mechanism utilizes a first hollow clamping seat 30 and a second hollow clamping seat 40 symmetrically arranged on both sides of the U-shaped base 10. The clamping rods 50 provide installation space, and their symmetrical arrangement ensures a uniform distribution of clamping force. Several sets of evenly spaced flexible spring-loaded clamping rods 50, inserted into the surfaces of the first hollow clamping seat 30 and the second hollow clamping seat 40 on the side in contact with the tube packaging box, can adapt to the shape of the tube packaging box, achieving flexible clamping and avoiding damage to the packaging box. Guide cylinders 32, installed inside the outer shell 31 of the first hollow clamping seat 30 and the second hollow clamping seat 40 near the flexible spring-loaded clamping rods 50, are the same number, corresponding in position, and of the same size, and are inserted into each other. The flexible spring-loaded clamp 50 can guide the movement of the flexible spring-loaded clamp 50, ensuring its stability. The hemispherical soft cap 53 installed at the end of the flexible spring-loaded clamp 50 that contacts the tube packaging box further increases the softness of the contact with the packaging box and prevents scratches. The flexible return spring 34 installed at the end of the flexible spring-loaded clamp 50 away from the soft cap 53 can automatically reset the flexible spring-loaded clamp 50 after the clamping action is completed, preparing for the next clamping operation. The overall structure works together to achieve effective clamping and stable operation of the flexible folding and shaping of the tube packaging box.

[0018] Furthermore, the piston rods 21 of the two sets of servo cylinders 20 are respectively connected to the ends of the first hollow clamp 30 and the second hollow clamp 40, so that the servo cylinders 20 can directly drive the first hollow clamp 30 and the second hollow clamp 40 to move, thereby achieving precise clamping and releasing actions and ensuring the accuracy of the operation of the roll tube packaging box.

[0019] Specifically, one end of the flexible rebound clamp 50 is inserted into the flexible return spring 34, and a limiting plate 51 is installed on the flexible rebound clamp 50, so that the flexible rebound clamp 50 can compress the flexible return spring 34 to achieve rebound when subjected to pressure. At the same time, the limiting plate 51 can prevent the flexible rebound clamp 50 from coming out of the guide cylinder 32, ensuring the stability of its movement.

[0020] It is worth noting that the flexible rebound clamp 50 is inserted into the flexible return spring 34 by a length of 5-15cm, which ensures that there is sufficient connection length between the flexible rebound clamp 50 and the flexible return spring 34, thus guaranteeing the stability of the connection between the two, and also providing a suitable elastic stroke for the rebound of the flexible rebound clamp 50.

[0021] The inner wall of the outer shell 31, away from the flexible spring-loaded clamp 50, is equipped with fixed posts 33 that are the same number, corresponding in position, and of the same size as the flexible return springs 34 and are plugged into each other. The distance between the fixed posts 33 and the ends of the flexible spring-loaded clamp 50 is the same as the length of the flexible spring-loaded clamp 50 extending out of the outer shell 31, so that the flexible return springs 34 can be stably installed in the outer shell 31. When the flexible spring-loaded clamp 50 moves, the flexible return springs 34 can be accurately compressed and reset, ensuring the normal operation of the flexible spring-loaded clamp 50.

[0022] In addition, the end of the flexible rebound clamp 50 is provided with a connecting screw hole 52, and the soft cap 53 is coaxially connected with a threaded post 54 that is compatible with the size of the connecting screw hole 52 and is threadedly connected, so that the soft cap 53 can be easily installed and disassembled, and is easy to replace and maintain. At the same time, it also ensures the firmness of the connection between the soft cap 53 and the flexible rebound clamp 50.

[0023] The working principle of the flexible folding and shaping fixture for this roll tube packaging box: First, place the tube packaging box in a suitable position inside the U-shaped base 10; then, activate the servo cylinders 20 on both sides, and extend their piston rods 21 to push the first hollow clamp 30 and the second hollow clamp 40 to move towards the tube packaging box respectively. As the hollow clamp moves, the hemispherical soft cap 53 on the flexible spring-loaded clamp 50 first contacts the roll tube packaging box; under the continuous clamping force, the flexible spring-loaded clamp 50 will retract into the guide cylinder 32, compressing the flexible return spring 34, and the limiting plate 51 prevents it from coming out; since the flexible spring-loaded clamp 50 is evenly and equidistantly arranged, it can adapt well to the shape of the packaging box and achieve flexible clamping. During the clamping process, the fixed column 33 provides stable support for the flexible return spring 34; after the folding and shaping operation is completed, the piston rod 21 of the servo cylinder 20 retracts, driving the first hollow clamp 30 and the second hollow clamp 40 away from the tube packaging box; at this time, the compressed flexible return spring 34 resets, pushing the flexible rebound clamp 50 to extend and return to the initial state, so that the processed tube packaging box can be taken out from the U-shaped base 10.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
