The adjusting rod is rotatably connected to the movable seat, and the ejector pins are installed on the adjusting rod. Content of the Utility Model

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a box body demoulding mechanism for a box holding device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A box body demoulding mechanism for a box holding device includes a mounting arm installed on the box holding device, a box holding driver installed at the bottom end of the mounting arm, a box holding plate installed at the output end of the box holding driver, and a scraping and demoulding component installed at the bottom of the mounting arm. The scraping and demoulding component includes a seat body, a scraping plate, and an elastic resetting member. The seat body is installed on the mounting arm and is located above the box holding plate. A rotating ear is arranged in the middle of the scraping plate, and the rotating ear is rotatably connected to the seat body. One end of the elastic resetting member is connected to the seat body, and the other end of the elastic resetting member is connected to the scraping plate. The seat body is provided with a rotating groove, and the rotating ear is rotatably arranged in the rotating groove. The elastic resetting member is used to provide a reset elastic force to the scraping plate. A demoulding space is formed between the box holding plate and the scraping plate; in the normal state, one side wall of the rotating ear abuts against the bottom wall of the rotating groove.

[0006] Further, a plurality of locking holes are arranged in a straight line from top to bottom on the mounting arm, and the locking holes are detachably connected with locking members. The seat body is locked on the mounting arm through the locking members.

[0007] Further, the seat body is provided with an adjusting groove communicated with the locking hole, and one end of the locking member penetrates through the adjusting groove and is connected to the locking hole of the mounting arm.

[0008] Further, the installation arm is provided with a vertical guide rail, and the seat body is slidably connected to the vertical guide rail.

[0009] Further, the seat body is provided with a rotating pin, the rotating pin transversely penetrates the rotating groove, and the rotating ear is rotatably connected to the rotating pin.

[0010] Further, the elastic resetting member is a spring.

[0011] Further, the number of the elastic resetting members is two, and the two elastic resetting members are located on both sides of the rotating ear.

[0012] Further, the box-holding driver is a cylinder.

[0013] Advantages of the utility model: In practical applications, the box body demolding mechanisms of the two box-holding devices are arranged oppositely, the pressing box mold moves up and down between the two box-holding devices, and the box body demolding mechanisms of the two box-holding devices cooperate to demold the box body from the pressing box mold; specifically, the processed and formed box body (such as: a box body with edge wrapping formed, etc.) is sleeved outside the pressing box mold, the box-holding device drives the box body demolding mechanism to move to the demolding position, the pressing box mold drives the box body to rise and enters the demolding space. When there is a small gap between the pressing box mold and the edge scraping plate, the edge scraping plate can abut against the edge of the top port of the box body. As the pressing box mold continues to rise, the edge scraping plate blocks the box body, so that the box body is demolded from the pressing mold. At this time, the box-holding cylinder drives the box-holding plate to approach the box body, so that the box-holding plates of the two box body demolding mechanisms hold the box body tightly. When an abnormal situation occurs where there is no gap between the pressing box mold and the edge scraping plate, the rising of the pressing box mold will lift the edge scraping plate (the edge scraping plate will rotate upward), until the edge scraping plate slides along the side wall of the pressing box mold to separate the box body from the pressing box mold. After the box body is completely demolded from the pressing box mold, the edge scraping plate will rotate downward and reset under the action of the elastic resetting member until the side wall of the rotating ear on the edge scraping plate abuts against the bottom wall of the rotating groove, so as to facilitate the demolding of the next box body. During this process, the elastic resetting member can not only provide the reset elastic force to the edge scraping plate to ensure that the edge scraping plate can normally complete the box body demolding action, but also play a role in buffering and protection to avoid hard impact collision between the edge scraping plate and the pressing box mold. The structure of the utility model is simple, which is convenient for demolding the box body, and the demolding stability of the box body is good, ensuring the quality of the box body after demolding.

[0020] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with embodiments and the accompanying drawings. The content mentioned in the embodiments does not limit the present utility model.

[0021] As Figures 1 to 4 shown, a box body demolding mechanism for a box-holding device provided by the present utility model includes an installation arm 1 installed on the box-holding device, a box-holding driver 2 installed at the bottom end of the installation arm 1, a box-holding plate 3 installed at the output end of the box-holding driver 2, and an edge-scraping demolding assembly 4 installed at the bottom of the installation arm 1. The edge-scraping demolding assembly 4 includes a base body 5, an edge-scraping plate 6, and an elastic reset member 7. The base body 5 is installed on the installation arm 1 and is located above the box-holding plate 3. A rotating ear 8 is provided in the middle of the edge-scraping plate 6. The rotating ear 8 is rotatably connected to the base body 5. One end of the elastic reset member 7 is connected to the base body 5, and the other end of the elastic reset member 7 is connected to the edge-scraping plate 6. The base body 5 is provided with a rotating groove 9, and the rotating ear 8 is rotatably arranged in the rotating groove 9. The elastic reset member 7 is used to provide a reset elastic force to the edge-scraping plate 6. A demolding space is formed between the box-holding plate 3 and the edge-scraping plate 6; as Figure 1 described, in the normal state, one side wall of the rotating ear 8 abuts against the bottom wall of the rotating groove 9.

[0022] In practical applications, the box body demolding mechanisms of two box-holding devices are arranged oppositely. The box-pressing mold 15 moves up and down between the two box-holding devices. The box body demolding mechanisms of the two box-holding devices cooperate to demold the box body 16 from the box-pressing mold 15; specifically, the processed box body 16 (such as: a box body 16 with edge wrapping formed, etc.) is sleeved outside the box-pressing mold 15. The box-holding device drives the box body demolding mechanism to move to the demolding position. The box-pressing mold 15 drives the box body 16 to rise and enters the demolding space, as Figure 1 and Figure 3As shown, when there is a small gap between the pressing box mold 15 and the scraping edge plate 6, the scraping edge plate 6 can abut against the top port edge of the box body 16. As the pressing box mold 15 continues to rise, the scraping edge plate 6 blocks the box body 16, causing the box body 16 to be demolded from the pressing mold. At this time, the box-holding cylinder drives the box-holding plate 3 to approach the box body 16, so that the box-holding plates 3 of the two box demolding mechanisms hold the box body 16 tightly. As Figure 2 and Figure 4 shown, when an abnormal situation occurs where there is no gap between the pressing box mold 15 and the scraping edge plate 6, the rising of the pressing box mold 15 will lift the scraping edge plate 6 (the scraping edge plate 6 will rotate upward), until the scraping edge plate 6 slides along the side wall of the pressing box mold 15 to separate the box body 16 from the pressing box mold 15. After the box body 16 is completely demolded from the pressing box mold 15, the scraping edge plate 6 will rotate downward to reset under the action of the elastic resetting member 7 until the rotating ear 8 on the scraping edge plate 6 abuts against the bottom wall of the rotating groove 9 with its side wall, so as to facilitate the demolding of the next box body 16. During this process, the elastic resetting member 7 can not only provide the reset elastic force to the scraping edge plate 6 to ensure that the scraping edge plate 6 can normally complete the demolding action of the box body 16, but also play a role of buffering and protection to avoid hard impact collision between the scraping edge plate 6 and the pressing box mold 15. The structure of the utility model is simple, which is convenient for demolding the box body 16, and the demolding stability of the box body 16 is good, ensuring the quality of the box body 16 after demolding.

[0023] In this embodiment, a plurality of locking holes 10 are arranged in a straight line from top to bottom on the mounting arm 1. The locking holes 10 are detachably connected with locking members 11, and the seat body 5 is locked on the mounting arm 1 through the locking members 11; specifically, the locking holes 10 are threaded holes and the locking members 11 are bolts. By connecting the locking members 11 with the locking holes 10 at different heights, the seat body 5 is locked at different height positions on the mounting arm 1, so as to realize the height adjustment of the scraping edge plate 6 to meet the demolding of box bodies 16 with different specifications.

[0024] In this embodiment, the seat body 5 is provided with an adjusting groove 12 communicating with the locking holes 10, and one end of the locking member 11 passes through the adjusting groove 12 and is connected with the locking hole 10 of the mounting arm 1. This structural design facilitates the adjustment of the height of the seat body 5 on the mounting arm 1.

[0025] In this embodiment, the mounting arm 1 is provided with a vertical guide rail 13, and the seat body 5 is slidably connected with the vertical guide rail 13. When adjusting the height position of the seat body 5 on the mounting arm 1, the seat body 5 slides up and down along the vertical guide rail 13 to improve the stability of adjusting the seat body 5.

[0026] In this embodiment, the seat body 5 is provided with a rotating pin 14, the rotating pin 14 transversely penetrates the rotating groove 9, and the rotating ear 8 is rotatably connected with the rotating pin 14. The rotating ear 8 rotates in the rotating groove 9 around the rotating pin 14, improving the rotating stability of the rotating ear 8 and the scraping edge plate 6.

[0027] In this embodiment, the elastic reset member 7 is a spring.

[0028] In this embodiment, the number of the elastic reset members 7 is two, and the two elastic reset members 7 are located on both sides of the rotating ear 8. This structural design makes the force on the scraping edge plate 6 uniform and improves the working stability of the scraping edge plate 6.

[0029] In this embodiment, the holding box driver 2 is a cylinder.

[0030] All the technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are the preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
