Abstract
Description
Technical Field
[0001] This utility model relates to the field of material transportation technology, specifically an adjustable vacuum adsorption roller. Background Technology
[0002] Vacuum adsorption rollers are industrial devices that utilize vacuum technology to achieve material adsorption and conveying. They are widely used in the processing and treatment of materials such as films, paper, non-woven fabrics, and lithium batteries. Vacuum adsorption rollers use a vacuum pump to extract the air inside the roller body, creating a negative pressure environment. The roller body surface is covered with suction holes. When the material comes into contact with the roller body, the pressure difference between the external atmospheric pressure and the negative pressure inside the roller body will generate an adsorption force, firmly adsorbing the material onto the roller body surface, thereby achieving stable material conveying.
[0003] Currently, the adsorption area of some adsorption rollers is usually set around the perimeter of the roller surface. As a result, a large amount of air is drawn into the part of the vacuum adsorption roller surface that is not in contact with the production material, which affects the airtightness of the vacuum adsorption roller and causes a significant decrease in its adsorption capacity. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable vacuum adsorption roller to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An adjustable vacuum adsorption roller, comprising:
[0007] The roller structure includes a support shaft, a rotating sleeve is rotatably sleeved on the outer surface of the support shaft, an air conveying channel is inserted inside the support shaft, a docking channel is opened on the upper side of the air conveying channel, and a number of air conveying grooves are arranged in a ring at equal angles on the inner side wall of the rotating sleeve.
[0008] A silicone suction cup is fixedly installed on the outer surface of a rotating sleeve, and the rotating sleeve is connected to the air delivery groove.
[0009] A support structure is fixedly installed at both ends of the roller structure.
[0010] Furthermore, an air intake port is interspersed on the side surface of the sleeve, and the air intake port is connected to the air delivery channel.
[0011] Furthermore, the silicone suction cup includes:
[0012] The base is fixedly installed at the outer opening of the air intake;
[0013] Deformation cylinder, which is fixedly installed on the upper side of the base;
[0014] The suction cup body is fixedly installed on the upper side of the deformation cylinder.
[0015] Furthermore, the supporting structure includes:
[0016] The outer end plate is fixedly installed at both ends of the sleeve;
[0017] The inner end plate is fixedly installed at both ends of the support shaft, and the inner end plate is sleeved inside the outer end plate.
[0018] The bearing has an inner ring that is sleeved on the inner end plate side surface, and an outer ring that is fixedly sleeved on the inner side of the outer end plate.
[0019] Furthermore, the supporting structure also includes:
[0020] Synchronizing gear, which is fixedly sleeved on the outer surface of the outer end plate;
[0021] A synchronous toothed belt, one end of which meshes with a synchronous gear.
[0022] Furthermore, the supporting structure also includes:
[0023] Mounting base, the mounting base being fixedly installed at one end of the inner end plate;
[0024] The upper end of the suction pipe is fixedly installed on one side of the mounting base, and the upper end of the suction pipe passes through the mounting base and the inner end plate and is connected to the gas delivery channel.
[0025] Compared with the prior art, the beneficial effects of this utility model are:
[0026] 1. The air inside the air supply channel is extracted to create a vacuum. At this time, the sleeve rotates normally relative to the support shaft. When a set of air inlets rotates to the top, the air supply groove connected below the set of air inlets aligns with the docking channel to form a complete air extraction channel. At this time, the air above the set of air inlets rushes into the relatively vacuum docking channel, creating an adsorption force. The air pressure is used to adsorb the object directly above the sleeve, achieving vacuum adsorption. The sleeve continues to rotate until the inner opening of the air supply groove is blocked by the side wall of the sleeve. The next set of air supply grooves aligns with the air supply channel. The sleeve always maintains that only the outer surface in contact with the object has adsorption force, while other positions are sealed to a certain extent to ensure airtightness and sufficient adsorption force on the surface in contact with the object.
[0027] 2. Each suction port has a silicone suction cup on its outer opening, and a thin-walled deformation cylinder is installed on the base. With the deformation capability of the silicone material itself, it can deform autonomously by adsorption force when in contact with the surface of the object, so that the edge of the opening on the suction cup body can fit relatively tightly with the surface of the object. This is to compensate for the situation where the suction port opening is located on the curved side surface of the sleeve, and there is a certain angle between the suction cup body and the surface of the object when rotating, resulting in a loose fit and affecting the adsorption force.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Please see Figure 1-6In this embodiment of the present invention, an adjustable vacuum adsorption roller includes a roller body structure 1, a silicone suction cup 2, and a support structure 3. The roller body structure 1 includes a support shaft 101, a sleeve 102 rotatably sleeved on the outer surface of the support shaft 101, an air supply channel 103 inserted inside the support shaft 101, a docking channel 104 on the upper side of the air supply channel 103, and a plurality of air supply grooves 105 arranged in a ring at equal angles on the inner side wall of the sleeve 102. The silicone suction cup 2 is fixedly installed on the outer surface of the sleeve 102, and the sleeve 102 is interconnected with the air supply grooves 105. The support structure 3 is fixedly installed at both ends of the roller body structure 1. An air intake 106 is inserted on the side surface of the sleeve 102, and the air intake 106 is interconnected with the air supply grooves 105.
[0037] Specifically, by using a vacuum pump or other air extraction equipment connected to the external support structure 3, the air inside the air delivery channel 103 is extracted to form a vacuum state. At this time, the sleeve 102 is rotating normally relative to the support shaft 101. When a set of air intake ports 106 rotates to the top, the air delivery groove 105 connected below the set of air intake ports 106 connects with the docking channel 104 to form a complete air extraction channel. At this time, the air above the set of air intake ports 106 rushes into the relatively vacuum docking channel 104, forming an adsorption force. The air pressure is used to adsorb the object directly above the sleeve 102, realizing vacuum adsorption. The sleeve 102 continues to rotate until the inner opening of the set of air delivery grooves 105 is blocked by the side wall of the sleeve 102. The next set of air delivery grooves 105 connects with the air delivery channel 103, always ensuring that only the outer surface of the sleeve 102 in contact with the object has adsorption force, while other positions are sealed to a certain extent, ensuring airtightness and giving the contact surface with the object sufficient adsorption force.
[0038] Example 1
[0039] like Figure 5-6 As shown, in this embodiment, the support structure 3 includes an outer end plate 301, an inner end plate 302, a bearing 303, a synchronous gear 304, and a synchronous toothed belt 305. The outer end plate 301 is fixedly installed at both ends of the sleeve 102; the inner end plate 302 is fixedly installed at both ends of the support shaft 101, and the inner end plate 302 is sleeved inside the outer end plate 301; the inner ring of the bearing 303 is sleeved with the side surface of the inner end plate 302, and the outer ring of the bearing 303 is fixedly sleeved with the inner side of the outer end plate 301; the synchronous gear 304 is fixedly sleeved on the outer surface of the outer end plate 301; one end of the synchronous toothed belt 305 meshes with the synchronous gear 304.
[0040] In this embodiment, the outer end plate 301 seals the openings at both ends of the sleeve 102, and the inner end plate 302 seals the openings at both ends of the support shaft 101. The multiple sleeves 102 are linked together or connected to the motor output end by the synchronous toothed belt 305 and the synchronous gear 304, driving each sleeve 102 to rotate independently relative to each support shaft 101, ensuring that the air intake direction is always facing one side.
[0041] like Figure 5-6 As shown, in this embodiment, the support structure 3 also includes a mounting base 306 and an air extraction pipe 307. The mounting base 306 is fixedly installed on one end of the inner end plate 302; the upper end of the air extraction pipe 307 is fixedly installed on one side of the mounting base 306, and the upper end of the air extraction pipe 307 passes through the mounting base 306 and the inner end plate 302 and is connected to the air supply channel 103.
[0042] In practice, the overall structure is relatively fixed by mounting base 306 and bolts. At the same time, mounting base 306 is fixedly connected to support shaft 101, so that support shaft 101 is also in a relatively fixed state. Then, suction is performed by vacuum pump and other structures connected to external suction pipe 307.
[0043] Example 2
[0044] Based on Embodiment 1, in order to compensate for the fact that in Embodiment 1, when the sleeve 102 rotates and the air inlet 106 adsorbs the object on the upper side, the outer opening of the air inlet 106 is actually an arc-shaped structure, which makes it impossible to fit tightly with the object.
[0045] like Figure 3-4 As shown, in this embodiment, the silicone suction cup 2 includes a base 201, a deformation cylinder 202, and a suction cup body 203. The base 201 is fixedly installed at the outer opening of the air intake 106; the deformation cylinder 202 is fixedly installed on the upper side of the base 201; and the suction cup body 203 is fixedly installed on the upper side of the deformation cylinder 202.
[0046] In specific implementation, a silicone suction cup 2 is provided at the outer opening of each air intake 106, and a deformation cylinder 202 with a thin side wall is provided at the base 201. With the deformation capability of the silicone material itself, it can deform autonomously by adsorption force when in contact with the surface of the object, so that the edge of the opening on the suction cup body 203 can fit relatively tightly with the surface of the object. This is to compensate for the situation where the opening on the air intake 106 is opened on the arc-shaped side surface of the sleeve 102, and there is a certain angle between the suction cup body 203 and the surface of the object when rotating, resulting in a loose fit and affecting the adsorption force.
[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
