[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figures 1-4 As shown, this application provides an automatic material pushing device for a carton opener, including: a placement frame 1, a side baffle 2 is provided on the top left side of the placement frame 1, and a sliding pressure plate 3 is provided on the top of the side baffle 2, and a carton board body 7 is provided at the rear end of the sliding pressure plate 3.

[0027] Specifically, such as Figure 1 As shown, a support block 4 is provided on the left side of the placement rack 1, and a guide mounting plate 5 is installed on the top of the support block 4. A limit stop 6 is connected to the outside of the guide mounting plate 5. The limit stop 6 is installed on the outside of the guide mounting plate 5 and can limit and block the rear top of the carton board body 7.

[0028] Specifically, such as Figure 2 As shown, a guide groove 8 is provided on the inner side of the side baffle 1 2, and a side baffle 2 14 is provided on the right side of the top of the placement rack 1. The inner structure of the side baffle 2 14 is the same as that of the side baffle 1 2. The side baffle 2 14 can be moved to the right at the top of the placement rack 1 to adapt to the size adjustment of the carton board body 7.

[0029] The bottom end of the side baffle 12 is provided with a guide counterweight assembly, which includes an extension support plate 12 and a guide connecting plate 20 at the bottom end of the extension support plate 12. A roller 18 is provided on the outer side of the guide connecting plate 20, and a counterweight block 21 is connected to the bottom end of the guide connecting plate 20. The guide counterweight assembly is used for adjusting and squeezing the carton board body 7.

[0030] The top of the placement rack 1 is provided with an extension component, which includes a bottom support plate 9. The bottom of the bottom support plate 9 is provided with a limit frame 10, and the inner side of the limit frame 10 is provided with a stretch adjustment plate 11. The extension component is used to extend and adjust the length of the bottom support plate 9.

[0031] Specifically, such as Figure 4 As shown, an elastic connector 19 is provided on the outer side of the guide connecting plate 20, and a fixed connecting plate 17 is connected to the top of the elastic connector 19. A roller 18 is installed on the top of the fixed connecting plate 17. The roller 18 contacts the ground wall of the side baffle 2 and limits its sliding. This can reduce friction and improve transmission efficiency during use. The elastic connector 19, together with the fixed connecting plate 17, can buffer and squeeze the roller 18 so that it is tightly attached to the bottom of the side baffle 2.

[0032] Specifically, such as Figure 2 As shown, the bottom end of the sliding pressure plate 3 is provided with an elastic connecting block 15, and the outer side of the elastic connecting block 15 is provided with a guide slide frame 16. The bottom end of the guide slide frame 16 is equipped with a bottom support plate 9. The bottom end of the sliding pressure plate 3 has a certain buffering efficiency due to the sliding connection between the elastic connecting block 15 and the guide slide frame 16, and then the bottom support plate 9 at the bottom end provides support and protection.

[0033] Specifically, such as Figure 3 As shown, the extension support plate 12 is installed on the top of the tension adjustment plate 11, and the bottom of the tension adjustment plate 11 is bonded with anti-slip rubber column 13. When the tension adjustment plate 11 slides inside the limit frame 10, the friction will be intermittently increased due to the protrusion of the anti-slip rubber column 13, thereby improving the stability during the adjustment process.

[0034] Specifically, such as Figure 2 As shown, the sliding pressure plate 3 is fixedly connected to the elastic connecting block 15, and the elastic connecting block 15 is slidably connected to the guide slide frame 16. The elastic connecting block 15 slides inside the guide slide frame 16, and its end is also connected by an elastic rod, which has a certain buffering and squeezing function.

[0035] Specifically, such as Figure 3 As shown, the extension support plate 12 is fixedly connected to the tension adjustment plate 11, and the tension adjustment plate 11 is slidably connected to the limit frame 10. The extension support plate 12 is fixedly connected to the tension adjustment plate 11 and slides inside the limit frame 10, which can drive the position between the extension support plate 12 and the bottom support plate 9 to be adjusted.

[0036] In this embodiment: by setting a guide groove 8 at the bottom end of the extension support plate 12, the guide connecting plate 20 is guided to slide, and the inner roller 18 is pressed tightly to reduce friction and improve the smoothness of transmission. Then, an adjustable counterweight 21 is set at the bottom end of the guide connecting plate 20, which can be adapted and adjusted when pushing different products. Extendable and adjustable extension support plates 12 are set on both sides of the bottom support plate 9, which can adjust the bottom support according to the different sizes of products.

[0037] The specific solution is as follows: During the feeding process of the carton erector, the distance between the side baffle 1 2 and the side baffle 2 14 is adjusted according to the feeding size of the carton body 7. Then, the bottom support plate 9 and the extension support plate 12 are also stretched and adjusted synchronously. At the same time, the limit block 6 is also adjusted to a suitable position on the outside of the guide mounting plate 5. The sliding pressure plate 3 is slid to the initial position in front of the top of the placement rack 1. Then, the carton body 7 is stacked on the inside. At this time, the extension support plate 12 is connected to the guide connecting plate 20 and slides on the inside of the guide slide 8. The bottom end is adapted to the rolling by the elastic support roller 18 to reduce friction and improve the transmission efficiency. The counterweight block 21 at the bottom end will also increase the downward pressure. The adjustment is controlled according to the thickness of the product.

[0038] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in the details for the sake of brevity.
