Description

Technical Field

[0001] The utility model relates to the technical field of depalletizing machines, in particular to a woven bag vacuum sucker. Background Art

[0002] Plastic woven bags are cheap, have good tensile and puncture resistance, and will not break easily, so they are widely used. Woven bag packaging materials are generally stacked and stored in factories. Depalletizers and conveyor belts are required to transport them to loading trucks. The bag grabbing mechanism set on the depalletizer is used to grab the bag and put it on the conveyor belt. The bag grabbing mechanism can be a mechanical grab or a suction cup.

[0003] The suction cup of the existing depalletizer is ideal for sucking flat coated woven bags and paper bags, but has poor suction effect on uneven materials. For example, when sucking woven bags without coating and inner bags, the woven bags are prone to wrinkles. After being sucked up, the middle of the four corners of the bag gradually sags and the negative pressure drops quickly, causing the bag to fall easily. Utility Model Content

[0004] The purpose of the utility model is to provide a woven bag vacuum suction cup, at least to solve one of the problems raised in the above background technology.

[0005] The technical solution of the utility model is:

[0007] A top plate, wherein a plurality of suction holes are formed on the top plate;

[0008] An outer plate, the outer plate is fixedly arranged on the outer edge of the top plate;

[0009] An inner side plate, the inner side plate is fixedly arranged on the inner edge of the top plate;

[0010] Wherein, the bottom surface of the top plate, a side wall of the outer side plate close to the top plate and a side wall of the inner side plate close to the top plate form an adsorption surface that can be tightly attached to the workpiece.

[0011] Furthermore, the top plate is formed by two square plates and two semicircular arc plates.

[0012] Furthermore, the outer plates include two square plates and two semicircular arc plates.

[0033] The utility model provides a woven bag vacuum suction cup through improvement. The technical solution of the utility model is:

[0034] like Figure 1 As shown,

[0035] A woven bag vacuum suction cup comprises a top plate 1, an outer side plate 2 and an inner side plate 3.

[0036] like Figure 2 As shown, the top plate 1 is provided with a plurality of suction holes 11, and the suction holes 11 are used to connect a fan to adsorb the woven bag.

[0037] like Figure 1As shown, the outer plate 2 is fixedly arranged on the outer edge of the top plate 1, and the inner plate 3 is fixedly arranged on the inner edge of the top plate 1. By providing the inner plate 3, the woven bag can be better fitted, the sealing is better during adsorption, and the adsorption is more stable. The provision of the outer plate 2 and the inner plate 3 can increase the overall structural strength of the suction cup, making it more stable. It can resist external pressure and impact, reduce the risk of deformation or damage of the suction cup during the adsorption process, and ensure long-term stable operation. At the same time, the presence of the outer plate 2 and the inner plate 3 can further limit the flow of air between the suction cup and the woven bag, and enhance the adsorption effect. The edge of the top plate 1 can be effectively sealed, gas leakage can be reduced, and the suction cup can be more closely fitted to the surface of the object, providing greater adsorption force. The outer plate 2 and the inner plate 3 can also protect the edge of the top plate 1, reducing the direct contact and friction between the top plate 1 and the woven bag. It helps to prevent wear and damage to the edge of the suction cup and extend the service life of the suction cup.

[0038] In some embodiments, the bottom surface of the top plate 1, the side wall of the outer side plate 2 close to the top plate 1, and the side wall of the inner side plate 3 close to the top plate 1 form an adsorption surface that can be closely attached to the workpiece. The adsorption surface is used to fit the woven bag, suck up the woven bag, and destacking or transporting it.

[0039] like Figure 2 As shown, the top plate 1 is formed by two square plates and two semi-circular plates. The outer plate 2 includes two square plates and two semi-circular plates. By setting the top plate 1 to be formed by two square plates and two semi-circular plates, on the one hand, it helps to evenly distribute the pressure on the contact surface between the top plate 1 and the object, which can not only improve the uniformity of adsorption and prevent damage to the woven bag or the suction cup due to excessive local pressure, but also ensure that the adsorption is more firm and reduce the risk of falling off; on the other hand, it enables the suction cup to adapt to woven bags loaded with contents of different shapes and sizes. Regardless of whether the upper surface of the woven bag is flat or curved, the top plate 1 formed by two square plates and two semi-circular plates can effectively fit the surface of the woven bag to achieve stable adsorption.

[0040] like Figure 3As shown, the angle between the outer plate 2 and the top plate 1 is α, α = 110°-130°. The large angle can solve the unevenness of the woven bag and avoid excessive wrinkles in the woven bag during adsorption. When the angle between the outer plate 2 and the top plate 1 is 110°-130°, the edge portion of the suction cup in contact with the object will form a tighter fit. This tighter fit can reduce the possibility of air leakage and thus enhance the stability of adsorption. In the case of needing to withstand greater external force or vibration, it can ensure that the suction cup is more firmly adsorbed on the object to prevent accidental falling off. And this angle can make the suction cup better adapt to woven bags of different shapes and curvatures. Different woven bag surfaces may have different bumps and inclination angles. By adopting large-angle outer plate 2 and top plate 1, the suction cup can better fit the surface of these woven bags and achieve a wider range of applicability.

[0041] In some embodiments, the inner side plate 3 has a smooth transition from thick to thin from top to bottom, so as to better fit the woven bag. The outer side plate 2 is higher than the inner side plate 3. Setting the outer side plate 2 higher than the inner side plate 3 can evenly distribute pressure, prevent air leakage, improve flexibility, and simplify manufacturing and maintenance.

[0042] In some embodiments, the thickness of the outer plate 2 is 5 mm-7 mm, and the thickness of the top plate 1 is 7 mm-9 mm.

[0043] In some embodiments, the outer plate 2, the top plate 1 and the inner plate 3 have a smooth transition. The smooth transition makes the vacuum suction cup of the woven bag sucking and carrying action more gentle, and will never pinch the package, deform or damage the package. The woven bag can always remain in a neat state.

[0044] In some embodiments, the top plate 1, the outer plate 2 and the inner plate 3 are all made of metal. The top plate 1, the outer plate 2 and the inner plate 3 made of metal have excellent durability and stability, reduce the frequency of repair and replacement, and reduce maintenance costs. The metal vacuum suction cup can withstand a larger workload and a harsher working environment, and is not easily damaged or deformed. During long-term use, the vacuum suction cup described in this embodiment can also maintain stable performance. On the other hand, metal is also easy to clean and maintain, and dirt and dust are not easily attached to the adsorption surface, so it is relatively simple and convenient to clean.

[0045] In some embodiments, the suction hole 11 is connected to a vortex blower. The vacuum suction cup described in this embodiment is connected to the vortex blower through the suction hole 11 to generate a vacuum environment, so that a negative pressure is formed between the suction cup and the woven bag, and then the woven bag is firmly adsorbed on the suction cup by atmospheric pressure. This adsorption method is easy to operate. You only need to start the vortex blower to achieve the adsorption and transportation of objects. And the magnitude of the adsorption force depends on the vacuum pressure, so even in the face of a heavier woven bag, there will be no danger due to overload. The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the utility model should be covered within the protection scope of the utility model.
