Description

Technical Field

[0001] The utility model belongs to the technical field of buffer devices, and particularly relates to a buffer device for facilitating the unloading of foam boxes. Background Technique

[0002] A foam box is a box-type packaging container made of foam plastic (porous plastic). Plastic foam is a plastic with many tiny air holes inside. In the current manufacturing process of foam boxes, with advanced technology, in a mold under a precisely controlled high-temperature and high-pressure environment, the foam material is perfectly shaped, and then a structurally stable foam box body and cover plate are formed. The combination of the two constitutes an efficient foam packaging box. However, at the end of this precision manufacturing process, when the packaging box is successfully demolded from the mold, a common challenge is that they directly contact the ground. This unbuffered landing method may not only cause damage to the surface of the foam box, affecting its aesthetics and protection performance, but also may contaminate the surface of the box body due to unclean ground, thus affecting its use quality and cleanliness;

[0003] After retrieval, the Chinese patent with the publication number CN215203086U discloses a buffer device for facilitating the unloading of foam boxes, including a foam box receiving mechanism, a buffer channel, and a foam box sorting mechanism. Among them, a foam box receiving mechanism is arranged below the foam box forming equipment. The foam box receiving mechanism is a funnel, and the funnel is used to receive the foam packaging boxes dropped by the forming equipment. A plurality of buffer channels are arranged at the bottom of the funnel.

[0004] The buffer channels used above have a relatively poor buffering effect on the foam boxes, cannot well protect the falling foam boxes, cannot adjust the buffering limit according to the size of the foam boxes, and reduce the applicable range of equipment use. Content of the Utility Model

[0020] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection specifically claimed by the present utility model.

[0021] As Figure 1-2 shown, a buffer device for facilitating the unloading of foam boxes includes a buffer channel 1. Two guide holes are opened on both sides of the buffer channel 1. Guide rods 2 are slidably installed inside the guide holes. A buffer plate 3 is fixed between one ends of the two guide rods 2 and inside the buffer channel 1. Two first mounting blocks 6 are fixed on one side of the buffer channel 1. An L-shaped connecting rod 7 is slidably installed through the outer wall of the first mounting block 6. One end of the L-shaped connecting rod 7 is fixed with a sleeve 8 sleeved on the guide rod 2. A solidifying bolt 9 that can fix the sleeve 8 is screwed on the top of the sleeve 8, which can adjust the fixing position of the sleeve 8 and the guide rod 2, adapt to different sizes of foam types, and improve the flexibility of equipment use. A driving component is provided on one side of the buffer channel 1 to enable the two L-shaped connecting rods 7 to reciprocate synchronously; the structure is simple. The driving component drives the two L-shaped connecting rods 7 to reciprocate synchronously. The L-shaped connecting rod 7 drives the guide rod 2 to reciprocate. The guide rod 2 drives the two buffer plates 3 to move, and enables the two buffer plates 3 to reciprocate synchronously, so that when the foam box falls in the buffer channel 1, the two buffer plates 3 intermittently clamp the foam box, reducing the falling speed and height of the foam box, thereby improving the buffering effect on the foam box.

[0022] As Figure 1-2 shown, a plurality of rubber protrusions 4 are fixed on the opposite sides of the two buffer plates 3. A cavity is provided inside the rubber protrusions 4, which improves the buffering effect on the foam box and avoids the foam box from being pinched, which is quite practical.

[0023] As Figure 1-3As shown in the figure, the driving component includes a motor 11 fixed to one side of the buffer channel 1. A turntable 12 is fixed to the output shaft of the motor 11. A limiting block 13 is fixed to one side of the outer wall of the turntable 12. A second mounting block 14 is fixed to the outer wall of the buffer channel 1 and below the turntable 12. A second connecting rod 15 is slidably mounted through the top of the second mounting block 14. A mounting plate 16 is fixed to the top of the second connecting rod 15. A limiting groove 17 slidably connected to the limiting block 13 is formed on one side of the mounting plate 16. Two first connecting rods 10 are rotatably mounted at the bottom of the second connecting rod 15. The other ends of the first connecting rods 10 are rotatably connected to one end of an L-shaped connecting rod 7. The structure is simple and the operation is convenient. The motor 11 drives the turntable 12 to rotate. The turntable 12 drives the limiting block 13 to rotate. The limiting block 13 cooperates with the limiting groove 17 to drive the second connecting rod 15 to reciprocate up and down. The second connecting rod 15 drives the L-shaped connecting rod 7 to reciprocate through the first connecting rods 10;

[0024] As Figure 1-2 shown in the figure, a guiding plate inclined outward is provided at the top of the buffer plate 3, which is convenient for the foam box to accurately enter the buffer channel 1 and is quite practical;

[0025] As Figure 1-2 shown in the figure, a connecting plate 5 is fixed between one ends of the two guide rods 2 and outside the buffer channel 1, which increases the installation stability of the guide rods 2 and is quite practical.

[0026] The working principle of the present utility model is as follows: According to the size of the foam box, the fixing position of the sleeve 8 and the guide rod 2 can be adjusted. Then, the motor 11 is started. The motor 11 drives the turntable 12 to rotate. The turntable 12 drives the limiting block 13 to rotate. The limiting block 13 cooperates with the limiting groove 17 to drive the second connecting rod 15 to reciprocate up and down. The second connecting rod 15 drives the L-shaped connecting rod 7 to reciprocate through the first connecting rods 10. The L-shaped connecting rod 7 drives the guide rod 2 to reciprocate. The guide rod 2 drives the two buffer plates 3 to move and makes the two buffer plates 3 reciprocate synchronously. When the foam box falls in the buffer channel 1, the two buffer plates 3 intermittently clamp the foam box, reducing the falling speed and height of the foam box, thereby improving the buffering effect on the foam box.

[0027] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special explanation and limitation.
