Description

Technical Field

[0001] This utility model relates to the field of packaging inspection, and in particular to a protective packaging box impact resistance testing device. Background Technology

[0002] Packaging boxes are containers produced and used according to certain technical methods during the product circulation and storage process to protect products, facilitate storage and transportation, and promote sales. They are generally made of rigid or semi-rigid materials, with high strength and are not easily deformed. In order to ensure that the packaging boxes can protect the products, they need to undergo impact resistance testing after production.

[0003] In existing technologies, when testing the impact resistance of packaging boxes, a set of heavy objects is usually lifted from the air by a device and then released to fall on the packaging box. The damage to the packaging box can be observed to determine whether the packaging box meets the impact resistance requirements. However, some packaging boxes are made of semi-rigid materials and have a certain degree of elasticity. When the heavy objects come into contact with their surface, there is a risk of rebound. The rebounding heavy objects can easily injure the operators, and the overall safety of the device is poor. Therefore, a packaging box impact resistance testing device with protective effect is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a protective packaging box impact resistance testing device, which aims to improve the problem in the prior art that "using heavy objects to hit the packaging box to test its impact resistance poses a risk of rebound and injury."

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective packaging box impact testing device, comprising a base, a support frame fixedly connected to the upper surface of the base, a top plate fixedly connected to the upper surface of the support frame, a movable plate slidably connected to the inner wall of the support frame, the movable plate being configured as a hollow convex-shaped flat plate, a lifting component provided on the inner wall of the support frame, an impact component provided on the inner wall of the movable plate, two sets of extrusion wheels rotatably connected to the inner wall of the movable plate, the two sets of extrusion wheels being symmetrically arranged about the center line of the movable plate as the axis of symmetry, and a gripping and releasing component provided on the upper surface of the movable plate;

[0006] The impact assembly includes a slide bar that slides at the center of the two sets of extrusion rollers. A mounting plate is fixedly connected to the lower surface of the slide bar, and a weight is fixedly connected to the lower surface of the mounting plate by a fixing screw.

[0011] As a further description of the above technical solution:

[0012] A connecting rod is fixedly connected to the upper surface of the insert block, and the connecting rod passes through and is slidably connected to the upper surface of the moving plate.

[0013] As a further description of the above technical solution:

[0014] An electric push rod is fixedly connected to the upper surface of the movable plate. A hinge seat is fixedly connected to the left end of the output shaft of the electric push rod. A hinge rod is hinged to the inner wall of the hinge seat. The front end of the hinge rod is hinged to the rear end of the connecting rod.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting a sliding rod, since the heavy object is fixedly connected to the lower surface of the mounting plate by fixing bolts, and the mounting plate is fixed to the lower surface of the sliding rod, and the sliding rod itself is restricted by multiple sets of compression wheels to only move vertically up and down, even if the heavy object rebounds after contacting the packaging box, it cannot move in all directions, but can only move vertically up and down. This can prevent the heavy object from rebounding and injuring the operator, and the overall device has good safety.

[0023] 2. In this utility model, by restricting the weight to only move up and down, it can be ensured that the weight falls to the same position each time during the experiment, thus ensuring that the impact position remains unchanged.

[0030] 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.

[0031] Reference Figures 2-4 An embodiment of this utility model provides: a packaging box impact resistance testing device with protective effect, including a base 1 for supporting the overall device, a support frame 2 for supporting the movement of a movable plate 4 fixedly connected to the upper surface of the base 1, a top plate 3 for supporting a lifting component 6 fixedly connected to the upper surface of the support frame 2, a movable plate 4 for determining the lifting height of a heavy object 53 slidably connected to the inner wall of the support frame 2, the movable plate 4 being configured as a hollow convex-shaped flat plate, a lifting component 6 for driving the movable plate 4 to move on the inner wall of the support frame 2, an impact component 5 for impacting the packaging box on the inner wall of the movable plate 4, two sets of extrusion wheels 9 rotatably connected to the inner wall of the movable plate 4, the two sets of extrusion wheels 9 being symmetrically arranged about the center line of the movable plate 4 as the axis of symmetry, the extrusion wheels 9 being configured as an I-shape, and a gripping component 7 being provided on the upper surface of the movable plate 4;

[0032] The impact assembly 5 includes a slide rod 51 for guiding the movement of the entire impact assembly 5. The slide rod 51 slides at the center position of the two sets of extrusion rollers 9. The slide rod 51 does not contact the inside of the moving plate 4, so as to prevent the slide rod 51 from moving downward due to friction. The lower surface of the slide rod 51 is fixedly connected to a mounting plate 52 for supporting the fixing screw 54. The lower surface of the mounting plate 52 is fixedly connected to a weight 53 by the fixing screw 54. The fixing screw 54 and the weight 53 are threadedly connected, and the mounting plate 52 is plugged in.

[0033] Reference Figures 1-3 A partition sleeve 55 is fitted onto the outer wall of the fixing screw 54. By setting the partition sleeve 55, it can be ensured that the mounting plate 52 and the weight 53 remain horizontal at their respective close ends, thus ensuring that the weight 53 faces the packaging box. The gripping and releasing assembly 7 includes an insert block 74 for fixing the slide rod 51. The insert block 74 is slidably connected to the inner wall of the moving plate 4 and can slide left and right on the inner wall of the moving plate 4. The outer wall of the slide rod 51 is provided with a slot 76 for accommodating the insert block 74. The insert block 74 is inserted into the inner wall of the slot 76. When the insert block 74 is in the inner wall of the slot 76, the slide rod 51 will be restricted from moving up and down. A connecting rod 75 for driving the insert block 74 to move is fixedly connected to the upper surface of the insert block 74. The connecting rod 75 passes through and is slidably connected to the moving plate. On the upper surface of 4, when the connecting rod 75 moves left and right, the insert 74 will be driven to move synchronously. An electric push rod 71 is fixedly connected to the upper surface of the moving plate 4. A hinge seat 72 is fixedly connected to the left end of the output shaft of the electric push rod 71. A hinge rod 73 for transmitting power is hinged to the inner wall of the hinge seat 72. The front end of the hinge rod 73 is hinged to the rear end of the connecting rod 75. When the output shaft of the electric push rod 71 extends, its output shaft will drive the hinge seat 72 to move forward. The hinge seat 72 will push the rear end of the hinge rod 73. In this way, the front end of the hinge rod 73 can push the connecting rod 75 away from the slide bar 51. The connecting rod 75 moves outward and can drive the insert 74 to disengage from the slot 76. At this time, the impact component 5 will fall downward under the action of gravity and hit the packaging box.

[0034] Reference Figures 1-3The lifting assembly 6 includes a drive motor 62 that provides power for lifting. The drive motor 62 is a servo motor, and its speed and number of rotations can be controlled. Since servo motors are existing technology and can be implemented by those skilled in the art, they will not be described in detail here. The drive motor 62 is mounted on the upper surface of the top plate 3. The lower surface of the output shaft of the drive motor 62 is fixedly connected to a lifting screw 61 for moving the movable plate 4. The lifting screw 61 and the movable plate 4 are threaded together. By starting the drive motor 62, the lifting screw 61 can be rotated, thereby moving the movable plate 4 up and down. The upper surface of the base 1 is provided with a storage slot 8 for placing packaging boxes. By providing the storage slot 8, the packaging boxes can be prevented from moving randomly after being impacted. The top plate 3 is a hollow rectangular plate. The inner wall of the top plate 3 is also mirrored and rotatably connected with two sets of extrusion wheels 9. Through the cooperation of multiple sets of extrusion wheels 9, the stability of the slide bar 51 moving up and down can be further guaranteed.

[0035] Working principle: The packaging box to be tested is placed in the storage groove 8 on the upper surface of the base 1. The storage groove 8 can prevent the packaging box from moving randomly after being impacted, ensuring the stability of the packaging box position during the testing process. The electric push rod 71 is activated, causing its output shaft to retract. The output shaft drives the hinge seat 72 to move backward. The hinge seat 72 pulls the rear end of the hinge rod 73, which in turn causes the front end of the hinge rod 73 to pull the connecting rod 75 closer to the slide rod 51. The connecting rod 75 drives the insert block 74 to insert into the slot 76 on the outer wall of the slide rod 51. At this time, the slide rod 51 is restricted from moving up and down, thus completing the fixation of the impact component 5.

[0036] Then, the drive motor 62 can be started. The output shaft of the drive motor 62 will drive the lifting screw 61 to rotate. Because the lifting screw 61 is threadedly connected to the moving plate 4, the rotation of the lifting screw 61 will cause the moving plate 4 to move upward along the inner wall of the support frame 2. The impact assembly 5, the extrusion wheel 9, and the gripping assembly 7 and other components on the moving plate 4 will rise accordingly. After rising to the set height, the drive motor 62 will stop working. At this time, the electric push rod 71 can be started again to extend its output shaft. Its output shaft will drive the hinge seat 72 to move forward, and the hinge seat 72 will push the hinge rod. At the rear end of 73, the front end of the hinge rod 73 pushes the connecting rod 75 away from the slide rod 51. The connecting rod 75 drives the insert block 74 to disengage from the slot 76. At this time, the impact component 5 loses its restraint and falls downward under the action of gravity. The weight 53 is fixed to the lower surface of the mounting plate 52 by the fixing screw 54. The mounting plate 52 is fixed to the lower surface of the slide rod 51. The slide rod 51 can only move vertically up and down under the restraint of the two sets of extrusion wheels 9. Therefore, the weight 53 can only fall vertically to impact the packaging box. By observing the damage to the packaging box after the impact, it can be determined whether its impact resistance meets the requirements.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
