[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1: As shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, an embodiment provided by the present utility model: A feeding device of an automatic label removing machine, including a base 1, a label removing mechanism 2 is installed on the base 1, and an adsorption mechanism 3 is installed on the label removing mechanism 2. The adsorption mechanism 3 is used to adsorb the waste products remaining after label removal;

[0030] The adsorption mechanism 3 includes a sealing cover 31 for sealing the label removing mechanism 2. An air duct branch 32 is connected and installed on the sealing cover 31, and an exhaust blower 35 is connected and installed on the air duct branch 32. The exhaust blower 35 is used to create a negative pressure inside the label removing mechanism 2.

[0031] Specifically, by setting the adsorption mechanism 3, including the sealing cover 31, the air duct branch 32 and the exhaust blower 35, the effect of adsorbing the waste products remaining after label removal and preventing them from rising with the thimble is achieved.

[0032] The sealing cover 31 seals the label removing mechanism 2 to form a closed space. The air extraction fan 35 extracts the air in this space through the air path branch pipe 32, creating a negative pressure inside the label removing mechanism 2.

[0033] When the ejector body 241 ejects the finished product label, if the waste product is not completely separated from the plate, the negative pressure will pass through the needle-passing holes of the honeycomb plate 24 and generate an adsorption force on the surface of the operating table, firmly adsorbing and fixing the waste product to prevent it from rising with the ejector pin.

[0034] This design effectively solves the problem that the label removing effect is affected by incomplete separation of the waste product, and improves the stability and reliability of the label removing operation through the physical mechanism of negative pressure adsorption.

[0035] Embodiment 2: To achieve precise adjustment and stable operation of the label removing mechanism, as Figure 2 、 Figure 4 shown, in this embodiment, the label removing mechanism 2 includes a top bracket 21. A top pin fixing plate 22 is installed on the top bracket 21, and a honeycomb plate 24 is installed on the top pin fixing plate 22. On both sides of the upper end surface of the top bracket 21, side sealing strips 211 are fixedly installed respectively. The side sealing strips 211 are made of elastic rubber and are used to connect the top bracket 21 and the honeycomb plate 24. While restricting the horizontal movement trajectory of the honeycomb plate 24, the sealing and stability of the structure are enhanced through close fitting. A moving cylinder 23 is installed at the rear end of the top pin fixing plate 22. The piston rod of the moving cylinder 23 is fixedly connected to the top bracket 21. By the telescopic movement of the piston rod, the top bracket 21 is pushed, causing the top pin fixing plate 22 to displace in the horizontal direction, and further enabling the ejector body 241 passing through the top pin fixing plate 22 to be clamped and positioned, meeting the positioning requirements of different label removing operations.

[0036] The honeycomb plate 24 is provided with needle-passing holes. At the relative position of the top pin fixing plate 22 below the needle-passing holes, there are positioning holes with a diameter larger than that of the needle-passing holes. The ejector body 241 is inserted into the honeycomb plate 24 through the needle-passing holes, and its bottom passes through the positioning holes of the top pin fixing plate 22 and is in dynamic contact with the upper end surface of the top bracket 21. The ejector body 241 can be easily inserted and removed in the needle-passing holes, facilitating maintenance and replacement; the positioning holes provide up and down movement space for the ejector body 241, enabling it to contact the top bracket 21 to provide support during label removal and also to flexibly perform the ejecting action. In addition, when the honeycomb plate 24 moves upward and contacts the lower end surface of the operating table, the external air extraction system inhales gas through the needle-passing holes, creating a negative pressure on the surface of the operating table, adsorbing the incompletely separated waste product on the operating table to prevent it from rising with the ejector body 241 and affecting the label removing effect.

[0037] Embodiment 3: To achieve the comprehensive support and functional coordination of the base for the equipment, as Figure 1 、 Figure 4 、 Figure 5As shown, in this embodiment, the base 1 includes a bottom bracket 11, on which four sliding rods 12 are evenly installed in a rectangular distribution. The top of the sliding rod 12 passes through the top bracket 21, the top pin fixing plate 22 and the honeycomb plate 24 in sequence, providing a guide and stability support for the vertical movement of the label removal mechanism. A lifting cylinder 13 is installed on the bottom bracket 11, and its output end is fixedly connected to the top bracket 21. The output end is driven by hydraulic pressure to perform lifting and lowering movements, and the height of the top bracket 21 in the vertical direction is accurately controlled to meet the label removal operation requirements of trademark plates of different specifications.

[0038] The exhaust fan 35 is fixedly mounted on the bottom bracket 11, and its air inlet end is connected to a connecting joint 33 through a bellows 34. The other end of the connecting joint 33 is connected to the air path branch pipe 32, and the air outlet end passes through the baffle on the front of the label remover. The exhaust fan 35 is equipped with a motor of specific power, which generates negative pressure through high-speed rotation, and extracts the air in the air path branch pipe 32 through the bellows 34 and the connecting joint 33, forming a stable adsorption force at the needle hole of the honeycomb plate 24, and cooperates with the label removal mechanism to complete the adsorption of waste. The base 1 integrates the sliding rod 12, the lifting cylinder 13 and the exhaust fan 35, which not only provides physical support, but also integrates the power regulation and air path adsorption functions to ensure the stability and efficiency of the overall operation of the automatic label remover feeding device.

[0039] When the utility model is used, the trademark plate to be removed is laid flat on the operating table, and the plate needs to cover the area just above the honeycomb plate 24 to ensure that the ejector body 241 can be aligned with the trademark position.

[0040] The horizontal position of the ejector fixing plate 22 is adjusted by moving the cylinder 23 to clamp the ejector body 241 , and the side sealing strip 211 limits the horizontal displacement of the honeycomb panel 24 to ensure the ejector positioning accuracy.

[0041] Start the lifting cylinder 13 to drive the top bracket 21 to rise vertically, driving the honeycomb panel 24 close to the bottom surface of the operating table: the slide bar 12 guides the top bracket 21 to rise steadily until the upper end surface of the honeycomb panel 24 is in close contact with the bottom surface of the operating table to form a sealed space.

[0042] The exhaust fan 35 is turned on to extract the air in the sealed space through the air branch pipe 32, the connecting joint 33 and the bellows 34, forming a negative pressure at the needle hole of the honeycomb plate 24. The negative pressure is transmitted to the surface of the operating table through the needle hole, adsorbing the trademark plate and possible residual waste to prevent them from shifting when the ejector pin is in action.

[0043] The bottom of the ejector body 241 is in dynamic contact with the upper end surface of the ejector bracket 21. When the ejector cylinder 13 continues to rise or is driven independently, the ejector body 241 passes through the needle hole and the plate to eject the finished trademark from the plate.

[0044] If the waste product is not completely separated from the plate, the negative pressure adsorption force acts on the waste product through the needle-piercing holes, firmly fixing it on the surface of the operating table and preventing it from rising with the thimble body 241. After the finished product trademark is ejected, the waste product remains on the operating table due to the adsorption force, achieving complete separation.

[0045] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
