[0002] The existing track is provided with a bearing surface to support both sides of the material belt according to the width of the material belt. Since the material belt is directly mounted on the bearing surface of the track, sometimes when the material belt is transmitted on the track, the friction between the material belt and the contact surface of the track is too large, resulting in a certain section of the material belt failing to be successfully transmitted forward, causing the entire section of the material belt to accumulate in one place, resulting in abnormal material jamming.

[0003] In view of this, it is necessary to provide an air-floating track to solve the above technical problems. Summary of the invention

[0004] In order to achieve the above-mentioned purpose, the present invention provides an air flotation track, which includes two track bodies arranged in parallel, the track body includes a first surface facing the other track body, a second surface away from the other track body, and an air flotation groove formed by a concave arrangement from the first surface to the second surface; an air flotation module includes a plurality of first air holes arranged at the bottom of the air flotation groove, a plurality of second air holes arranged at the top of the air flotation groove, and a connecting piece for connecting the first air holes, the second air holes and an air pump.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] In the description of the present invention, it is necessary to understand that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0038] like Figures 1 to 9 As shown, the air-floating track provided by the present invention comprises two track bodies 100 arranged in parallel, an air-floating module 200 located on the track bodies 100, and a material belt 300 located between the two track bodies 100. The material belt 300 is kept in a suspended state by the air-floating module 200, that is, it does not directly contact the track body 100, thereby preventing the excessive friction between the material belt 300 and the track body 100 from causing abnormal transmission of the material belt 300.

[0039] The extension direction of the track body 100 is the same as the transmission direction of the material belt 300. The distance between the two track bodies 100 can be adaptively adjusted according to the width of the material belt 300.

[0040] The track body 100 includes a first surface 101 facing the other track body 100, a second surface 102 facing away from the other track body 100, and an air flotation groove 103 formed concavely from the first surface 101 to the second surface 102. The first surfaces 101 of the two track bodies 100 face each other, the air flotation groove 103 is opened at the middle position of the first surface 101 along the height direction, the extension direction of the air flotation groove 103 is the same as the extension direction of the track body 100, and a conveying channel for conveying the material belt 300 is formed between the two air flotation grooves 103.

[0041] The air flotation module 200 includes a plurality of first air holes 201 disposed at the bottom of the air flotation tank 103, a plurality of second air holes 202 disposed at the top of the air flotation tank 103, and a connecting piece for connecting the first air holes 201 and the second air holes 202 to an air pump. The first air holes 201 and the second air holes 202 are connected to two different air pumps through the connecting piece, and the air pump is turned on to control the first air holes 201 and the second air holes 202 to inlet or outlet air and adjust the air pressure values ​​of the first air holes 201 and the second air holes 202, so as to apply a force (support force or suction force) to the material belt 300 to overcome the gravity of the material belt 300, so as to keep the material belt 300 in a suspended state.

[0042] Specifically, the distance L1 between the first surfaces 101 of the two rail bodies 100 facing each other is smaller than the width of the material strip 300, and the distance L2 between the two air flotation grooves 103 is larger than the width of the material strip 300. In this way, the edge portions of the material strip 300 on both sides are respectively located in the two air flotation grooves 103, and the first air holes 201 at the bottom of the air flotation grooves 103 and the second air holes 202 at the top are used to apply force to the edge portions of the material strip 300 to overcome the self-weight of the material strip 300, so that the material strip 300 is suspended in the air flotation grooves 103 without contacting the rail body 100.

[0043] The dimension of the air flotation groove 103 perpendicular to the first surface 101 is 4 mm to 5 mm, that is, the depth of the air flotation groove 103 is 4 mm to 5 mm. The depth of the air flotation groove 103 should not be too deep, otherwise the volume of the track body 100 will be increased, and the material strip 300 will easily contact the air flotation groove 103. The depth of the air flotation groove 103 should not be too shallow, otherwise the first air hole 201 and the second air hole 202 cannot stably and reliably apply a force to the material strip 300.

[0044] The dimension of the air flotation tank 103 along the height direction is 2.5 mm to 3.5 mm, that is, the height of the air flotation tank 103 is 2.5 mm to 3.5 mm. The height of the air flotation tank 103 should not be too large, otherwise the distance between the material strip 300 and the first air hole 201 or the second air hole 202 will be too large, and the first air hole 201 or the second air hole 202 will not be able to effectively apply force to the material strip 300; the height of the air flotation tank 103 should not be too small, otherwise it will easily cause the material strip 300 to contact the air flotation tank 103.

[0045] In order to prevent the material strip 300 from contacting the bottom of the air flotation tank 103 and causing the first air hole 201 to be blocked, a recessed portion 103a is provided at the bottom of the air flotation tank 103, and the first air hole 201 is located in the recessed portion 103a. Specifically, the bottom surface of the air flotation tank 103 is a wavy curved surface, and the wavy bottom surface has crests and troughs, and the location of the trough is the recessed portion 103a.

[0046] Similarly, to prevent the material strip 300 from contacting the top of the air flotation tank 103 and causing the second air hole 202 to be blocked, a recessed portion 103a is also provided on the top of the air flotation tank 103, and the second air hole 202 is located in the recessed portion 103a. Specifically, the top surface of the air flotation tank 103 is also a wavy curved surface, and the bottom surface of the wavy line has crests and troughs, and the position of the trough is the recessed portion 103a.

[0047] A plurality of first air holes 201 are arranged at intervals at the bottom of the air flotation tank 103 along the extension direction of the air flotation tank 103, and the first air holes 201 are located in the middle of the bottom of the air flotation tank 103, so as to better apply force to the material strip 300. A plurality of second air holes 202 are arranged at intervals at the top of the air flotation tank 103 along the extension direction of the air flotation tank 103, and the second air holes 202 are located in the middle of the top of the air flotation tank 103, so as to better apply force to the material strip 300.

[0048] Preferably, the first air hole 201 and the second air hole 202 are arranged opposite to each other, that is, the first air hole 201 and the second air hole 202 are symmetrically arranged along the central axis of the air flotation tank 103, so that the first air hole 201 and the second air hole 202 apply force to the material strip 300 at the same position, so that the material strip 300 can be stably suspended in the air flotation tank 103, and at the same time, the material strip 300 can be prevented from bending at the edge portion.

[0049] The connecting member includes a first connection port 203 for connecting with an air pump, and a first air channel 205 located in the track body 100 to connect the first connection port 203 and all the first air holes 201, wherein the first connection port 203 is located on the second surface 102 of the track body 100. The first air channel 205 includes a first main air channel extending along the extension direction of the track body 100 and connected with the first connection port 203, and a plurality of first branch air channels connecting the first main air channel and the first air holes 201, wherein the first branch air channels are perpendicular to the first main air channel. In this way, the air pump controls the air outlet or air intake of the first air holes 201.

[0050] The track body 100 also includes a second connection port 204 and a second air channel 206 located in the track body 100 to connect the second connection port 204 and all the second air holes 202. The second connection port 204 is located on the second surface 102 of the track body 100, and the second connection port 204 is located above the first connection port 203. The second air channel 206 includes a second main air channel extending along the extension direction of the track body 100 and connected to the second connection port 204, and a plurality of second branch air channels connecting the second main air channel and the second air holes 202. The second main air channel is parallel to the first main air channel and is located above the first main air channel, and the second branch air channel is perpendicular to the second main air channel. In this way, the air outlet or air intake of the second air hole 202 is controlled by the air pump.

[0051] The present invention also provides a method for using an air-floating track, which can be applied to the above-mentioned air-floating track, and comprises the following steps:

[0052] The material strip 300 is placed between two parallel track bodies (100), and two edges of the material strip 300 along the width direction are respectively located in the air flotation grooves 103 of the two track bodies 100;

[0053] Turn on the air pump to allow air to enter or blow through the first air holes 201 at the bottom of the air flotation tank 103 and the second air holes 202 at the top of the air flotation tank 103;

[0054] The material strip 300 is suspended in the air flotation tank 103 by adjusting the air pressure values ​​of the first air hole 201 and the second air hole 202 .

[0055] Reference Figure 7 In one embodiment, the first air hole 201 is controlled to blow air separately, and the air pressure value of the first air hole 201 is adjusted so that the material strip 300 is suspended in the air flotation tank 103, that is, the air pressure value of the second air hole 202 is zero.

[0056] Specifically, the two track bodies 100 are track body A and track body B. The air pressure value at the first air hole 201 on the track body A is P1, and the area of ​​the first air hole 201 on the track body A acting on the material strip 300 is S, which can be approximately regarded as the sum of the areas of all the first air holes 201 on the track body A, so the support force F11 applied by the first air hole 201 on the track body A to the material strip 300 is P1*S. The air pressure value at the first air hole 201 on the track body B is P2, and the support force F21 applied by the first air hole 201 on the track body B to the material strip 300 is P2*S.

[0057] It is understandable that, in order to suspend the material strip 300 in the air flotation tank 103, P1 and P2 need to be adjusted so that F11+F21=Mg (M is the mass of the material strip 300). At the same time, in order to keep the material strip 300 horizontal, P1=P2 needs to be maintained, that is, F11=F21=1 / 2Mg.

[0058] Of course, in this embodiment, only the first air hole 201 may be provided at the bottom of the air flotation tank 103 , and the second air hole 202 may be omitted.

[0059] Reference Figure 8 In another embodiment, the first air hole 201 is controlled to blow air, thereby generating a supporting force on the material strip 300; the second air hole 202 is controlled to let air in, thereby generating a suction force on the material strip 300. The first air hole 201 and the second air hole 202 work together to make the material strip 300 suspended in the air flotation tank 103.

[0060] Specifically, the two track bodies 100 are track body A and track body B. The air pressure value at the first air hole 201 on the track body A is P1, and the support force F11 of the first air hole 201 on the track body applied to the material belt 300 is P1*S; the air pressure value at the second air hole 202 on the track body A is P3, and the suction force F31 of the second air hole 202 on the track body applied to the material belt 300 is P3*S. The air pressure value at the first air hole 201 on the track body B is P2, and the support force F21 of the first air hole 201 on the track body applied to the material belt 300 is P2*S; the air pressure value at the second air hole 202 on the track body B is P4, and the suction force F41 of the second air hole 202 on the track body applied to the material belt 300 is P4*S.

[0061] It is understandable that, in order to suspend the material strip 300 in the air flotation tank 103, it is necessary to adjust P1, P2, P3, and P4 so that F11+F21+F31+F41=Mg (M is the mass of the material strip 300). In order to keep the material strip 300 horizontal, it is necessary to keep P1=P2, that is, F11=F21; P3=P4, that is, F31=F41.

[0062] Reference Fig. 9 In another embodiment, the first air hole 201 is controlled to allow air to flow in, thereby generating suction on the material strip 300; the second air hole 202 is controlled to allow air to flow in, thereby generating suction on the material strip 300, and the air pressure value of the first air hole 201 is controlled to be smaller than the air pressure value of the second air hole 202. The first air hole 201 and the second air hole 202 work together to make the material strip 300 suspended in the air flotation tank 103 while flattening the material strip 300.

[0063] Specifically, the two track bodies 100 are track body A and track body B. The air pressure value at the first air hole 201 on the track body A is P1, and the suction force F11=P1*S applied by the first air hole 201 on the track body to the material belt 300 is P3; the air pressure value at the second air hole 202 on the track body A is P3, and the suction force F31=P3*S applied by the second air hole 202 on the track body to the material belt 300 is P3. The air pressure value at the first air hole 201 on the track body B is P2, and the suction force F21=P2*S applied by the first air hole 201 on the track body to the material belt 300 is P2; the air pressure value at the second air hole 202 on the track body B is P4, and the suction force F41=P4*S applied by the second air hole 202 on the track body to the material belt 300 is P4.

[0064] It is understandable that, in order to suspend the material strip 300 in the air flotation tank 103, it is necessary to adjust P1, P2, P3, and P4 so that F31+F41=F11+F21+Mg (M is the mass of the material strip 300), and the air pressure value of the first air hole 201 is less than the air pressure value of the second air hole 202. At the same time, in order to keep the material strip 300 horizontal, it is necessary to keep P1=P2, that is, F11=F21; P3=P4, that is, F31=F41. For the track body A, F31=F11+1 / 2Mg; for the track body B, F41=F21+1 / 2Mg.

[0065] At the same time, since the first air holes 201 and the second air holes 202 on the track body A and the track body B are both negative pressure, an airflow will be generated from the center of the material belt 300 to the edge of the material belt 300, and the airflow applied to the material belt 300 will generate a lateral force from the center of the material belt 300 to the edge of the material belt 300 through friction. Under the action of this lateral force, the material belt 300 can be flattened.

[0066] Specifically, the lateral force applied by the first air hole 201 on the track body A to the material strip 300 is F12; the lateral force applied by the second air hole 202 on the track body A to the material strip 300 is F32. The lateral force applied by the first air hole 201 on the track body B to the material strip 300 is F22; the lateral force applied by the second air hole 202 on the track body B to the material strip 300 is F42. Since P1=P2, F12=F22, that is, F12 and F22 are of the same size and opposite directions; P3=P4, so F32=F42, that is, F32 and F42 are of the same size and opposite directions, so that the material strip 300 can be flattened.

[0067] In summary, the present invention sets the air flotation groove 103 on the first surface 101 of the track body 100, and sets the first air hole 201 and the second air hole 202 in the air flotation groove 103 to apply force to the material belt 300, so that the material belt 300 is suspended in the air flotation groove 103, thereby preventing the material belt 300 from directly contacting the track body 100, thereby reducing the transmission resistance and the risk of jamming of the material belt 300.
