Description

TECHNICAL FIELD

[0001] The present application relates to a feeding mechanism, in particular to a film fixed-length feeding mechanism. BACKGROUND

[0002] The air spring is generally composed of an upper cover, a rubber air bag, a lower seat and a rubber elastic support body, etc. It is used for the secondary damping suspension device of a vehicle, and is installed between the vehicle body and the bogie. Its main function is to transmit vertical load, buffer and absorb vertical and lateral vibrations. In actual use, the internal air pressure can be adjusted by using a height valve to ensure that the air spring maintains a constant height under different loads, and it is widely used on various vehicles. The rubber air bag is a key component that determines the performance and service life of the air spring. Its structure is similar to that of a tubeless tire, and it is composed of an inner rubber layer (airtight layer), an outer rubber layer, a cord reinforcement layer and a steel ring. The cord (cord reinforcement layer) bears the main load, while the outer rubber layer mainly protects the cord layer and should have good ozone aging resistance, weather resistance, flex resistance, adhesion to the cord layer and oil resistance, etc.

[0003] At present, the film of the air spring is rolled in the roll after being calendered, and the film is attached to the roll to prevent deformation of the film. The operator manually spreads the roll and pulls out the film, measures a certain length, and then cuts the film. Manual operation to pull the film has a large deformation, and manual cutting has a large error. The film is a soft and elastic material, and different rubber materials have different shrinkage conditions. Manual cutting of the film is not conducive to the continuity of the subsequent process, and usually a large amount of film cannot be cut and placed for use in the subsequent process (if too much film is cut, the film used later will shrink too much and the size will not be qualified for use), and repeated cutting has low efficiency. Manual cutting involves more hand contact, which can cause contamination of the rubber material and the introduction of impurities.

[0004] There is also a mechanical separation of the rubber material (or rubber sheet) and the cloth in the prior art, such as the announcement number: CN107187088A, a tire cord device for manufacturing automobile tire, including first rolling piece (2), support (4) and second rolling piece (10), support (4) is symmetrically provided with support table (5) below, second positioning piece (9) is installed between support table (5) and support (4), a pair of casters (6) is installed in the lower part of support (4), first positioning piece (7) is installed between casters (6), first guide rail (8) is arranged below first positioning piece (7), device handrail (1) is installed on support (4), first rolling piece (2) is arranged below device handrail (1), second rolling piece (10) is installed on the right side of support (4), first rolling piece (2) and second rolling piece (10) are provided with friction assembly (3) near the end of support (4), support piece (13) is installed on the upper right of support (4), guide body (12) is arranged on support piece (13), third rolling piece (14) and fourth positioning piece (11) are respectively connected to both ends of guide body (12), tire cord (15) is connected between third positioning piece (14) and first rolling piece (2), and pad cloth (16) is connected between third positioning piece (14) and second rolling piece (10). But the separated material is randomly wound, and there is no process of tightening or arranging the material, because the rubber sheet is an elastic material, and there is no corresponding control of the degree of tightening or the adjustment of the tightening stress after separation, which can also cause the rubber sheet to deform.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1:

[0042] like Figure 1 As shown, the film fixed-length feeding mechanism includes a winding assembly 1, a release roller 2, a peeling roller assembly 3, a floating adjustment assembly 4, a feeding assembly 5, a cutting assembly 6, a feeding plate 7, a first support 8, and a second support 9.

[0043] In this embodiment, the first support 8 and the second support 9 are arranged adjacent to each other. The winding assembly 1 and the release roller 2 are mounted on the first support 8, and the peeling roller assembly 3, the floating adjustment assembly 4, the feeding assembly 5, the cutting assembly 6, and the feeding plate 7 are mounted on the second support 9. The winding assembly 1 and the release roller 2 are positioned lower than the peeling roller assembly 3. The first support 8 and the second support 9 mainly serve a supporting function.

[0044] The winding assembly 1 comprises a winding motor 11 and a winding roller 12. The winding motor 11 is connected to the first support 8 and located below the winding roller 12. The two ends of the winding roller 12 are rotatably connected to the first support 8 through support seats, bearings and other connecting members. The winding motor 11 drives the winding roller 12 through belt transmission or chain transmission. The winding roller 12 is mainly used for winding the cloth.

[0045] The release roller 2 is located on the right side of the winding roller 12 and is rotatably connected to the first support 8 through support seats, bearings and other connecting members. The release roller 2 is used to install the material, i.e. the rubber material after calendering is wound on the cloth roll to form a material. Under the rotation of the feeding assembly 5 at the rear end, the release roller 2 can continuously release the material.

[0046] The stripping roller assembly 3 comprises a first stripping roller 31, a second stripping roller 32, a stripping cylinder 33, a support frame 34 and a first guide rail 35. The first stripping roller 31 and the second stripping roller 32 are connected with gears at one end or both ends. The bodies of the first stripping roller 31 and the second stripping roller 32 are smooth. The end portions of the first stripping roller 31 and the second stripping roller 32 are meshed through gears. The material is separated after extending from the release roller 2 to the middle of the first stripping roller 31 and the second stripping roller 32. The separated cloth A is wound on the winding roller 12 after passing around the first stripping roller 31. The separated rubber sheet B is output to the next process after passing around the second stripping roller 32.

[0047] The first stripping roller 31 and the second stripping roller 32 are meshable and separable, mainly realized by the stripping cylinder 33. The first stripping roller 31 is rotatably connected to the top left end of the second support 9 through support seats, bearings and other connecting members. The movement of the second stripping roller 32 is realized by the stripping cylinder 33. The second stripping roller 32 is rotatably connected to the support frame 34 through support seats, bearings and other connecting members. The support frame 34 can be a box-shaped structure with the top end and the left side empty. The right end of the support frame 34 is connected to the telescopic end of the stripping cylinder 33. The bottom of the support frame 34 is slidingly connected to the first guide rail 35. The action of the stripping cylinder 33 can realize the horizontal movement of the support frame 34 along the first guide rail 35, i.e. the meshing and moving away of the second stripping roller 32 and the first stripping roller 31. In this embodiment, the first stripping roller 31 and the second stripping roller 32 are meshed through gears and are synchronous, which can maintain the synchronous processing of the cloth A and the rubber sheet B after stripping, maintain consistency and reduce the problem of reattachment caused by asynchronization.

[0048] The floating adjusting assembly 4 comprises a floating rod 41, a floating rotating shaft 42, a floating roller 43 and a floating counterweight 44. The floating rotating shaft 42 is connected to the second support 9. The middle part of the floating rod 41 is rotatably connected to the floating rotating shaft 42. The floating roller 43 is connected to one end of the floating rod 41. The floating counterweight 44 is connected to the other end of the floating rod 41. The position of the middle part of the floating rod 41 can be set according to the required tensioning force. The floating adjusting assembly 4 adopts the lever principle. The tensioning force of the floating rotating shaft 42 is adjusted according to the weight of the floating counterweight 44. The floating counterweight 44 can be fixed to the end of the floating rod 41 by bolts.

[0049] As shown in Figure 1 The floating roller 43 is located between the peeling roller assembly 3 and the feeding assembly 5. The film B is wound to form a V shape between the peeling roller assembly 3, the floating roller 43 and the feeding assembly 5. The film B has elastic properties, and the elastic force of different materials is also different. The elastic properties of the film B need to be adjusted. In the embodiment, the floating roller 43 is arranged to stretch the film. At the same time, the floating counterweight 44 can be adjusted to adapt to different film properties.

[0050] The feeding assembly 5 comprises two feeding rollers 51. The two feeding rollers 51 are connected by belt transmission. The feeding rollers 51 are driven by a feeding motor. When there are multiple feeding rollers 51, two or more feeding rollers 51 can be connected by gears and chains to realize synchronous rotation. In the embodiment, the feeding motor can be controlled to rotate a certain number of turns and angles (the length of the feeding can be controlled) and then stop. The material will be fed to the next process.

[0051] The feeding plate 7 is connected to the right side of the second support 9. After the film is output by the feeding roller 51, it is vertically fed onto the feeding plate 7. The feeding plate 7 is vertically arranged. Due to the viscosity of the film, the cut film will stick to the feeding plate 7 and will not fall off, which is convenient for taking down.

[0052] The working process of the embodiment is as follows:

[0053] Before the working process of the embodiment, the material needs to be installed. After the film is rolled on the cloth roll after calendering, the material is installed on the release roller 2. At the same time, the peeling cylinder 33 is started to separate the first peeling roller 31 from the second peeling roller 32. The material is pulled out from between the first peeling roller 31 and the second peeling roller 32. At the same time, the cloth roll A and the film are manually separated. The cloth roll A is wound around the first peeling roller 31 and then wound on the winding roller 12. The film B is wound around the second peeling roller 32, then around the floating roller 43, and then around the two feeding rollers 51. It falls vertically from above and falls on the feeding plate 7. The cutting assembly 6 is installed on one side of the feeding plate 7. The initial installation of the material is completed. Figure 1The material is released between the release roller 2 and the first stripping roller 31, that is, it is a double-layer structure at this time, with the cloth A on the left and the film B on the right; after being stripped at the first stripping roller 31, only the cloth A enters the winding roller 12, and only the film B is fed to the cutting.

[0054] When the device is running, the film on the feeding plate 7 is cut for the first time and then taken away, the feeding motor of the feeding roller 51 is started, the feeding roller 51 starts to rotate clockwise, at the same time, the film B starts to feed with the feeding roller 51, the floating roller 43 starts to rotate around the floating shaft 42 as the film decreases, the feeding motor of the feeding roller 51 stops after rotating a certain number of turns and angles, the material will be fed onto the feeding plate 7, at the same time, the winding motor 11 starts to wind, after a certain time, the winding roller 12 connected by the chain starts to work, at the same time, the cloth A is continuously wound, driving the release roller 2 to rotate continuously, the cloth A and the film B are continuously released, the cloth A is wound by the winding roller 12, and the film B is released, which causes the film between the second stripping roller 32 and the left feeding roller 51 to continuously increase, and the floating roller 43 reverses at the same time to continue to straighten the film, ensuring that the film will not relax and deform. After a certain length of film is fed to the feeding plate 7, the whole device stops, and the cutting assembly 6 cuts the film B.

[0055] The embodiment realizes the stripping of the cloth A and the film B, the winding of the cloth A, and the cutting of the film B; during the feeding of the film, the floating adjustment assembly 4 straightens the film B to ensure that the film B will not relax and deform during the feeding process, the feeding length is controlled by setting the feeding parameters of the feeding motor, and the cutting assembly 6 is used for fixed-length cutting; the series of operations of feeding, winding and cutting in the embodiment can realize fixed-length feeding, improve efficiency, reduce accident rate, improve the quality of cut film, reduce deformation caused by manual tearing of the film, and accurately control the cutting length; improve the cutting efficiency of the film, and continuously connect the subsequent process, machine cutting, and reduce the risk of film pollution.

[0056] Embodiment two:

[0057] As shown in Figure 1 , Figure 2 based on embodiment one, the cutting assembly 6 includes a cutting support 61, a cutting walking motor 62, a cutting cylinder 63, and a cutting knife 64, the cutting support 61 is a U-shaped frame structure, welded on the right side of the second support 9 and suspended on the right side of the feeding plate 7, the second guide rail 65 is connected to the cutting support 61, one end of the cutting cylinder 63 is slidably connected to the second guide rail 65, the cutting walking motor 62 is connected to the cutting cylinder 63, and the other end of the cutting cylinder 63 is connected to the cutting knife 64. The cutting knife 64 is rotatably connected to the extension end of the cutting cylinder 63.

[0058] The cutting walking motor 62 provides power for the cutting cylinder 63 parallel to the width direction of the film B, and the cutting cylinder 63 can move horizontally along the second guide rail 65; the cutting cylinder 63 provides the cutting knife 64 with a feed perpendicular to the surface direction of the film B.

[0059] The cutting assembly 6 further comprises a pressing beam 66 and a sensor 67, both ends of the pressing beam 66 are connected to the cutting support 61, the pressing beam 66 is a through structure along the extension direction of the cutting cylinder 63, the cutting knife 64 passes through the through structure, and the sensor 67 is connected to the pressing beam 66. The pressing beam 66 can also be controlled by a cylinder to press on the film B or the original film B, so that the film B does not move during cutting.

[0060] The working process of the embodiment is as follows:

[0061] When the device is running, the film on the feeding plate 7 is cut for the first time and taken away, the sensor 67 detects that there is no film B, the device starts to run, the feeding motor of the feeding roller 51 starts to rotate clockwise, at the same time, the film B starts to feed with the feeding roller 51, the floating roller 43 starts to rotate around the floating shaft 42 as the film decreases, the feeding motor of the feeding roller 51 stops after rotating a certain number of turns and angles, the material will be fed onto the feeding plate 7, at the same time, the winding motor 11 starts to wind, starts for a certain time, the connecting chain drives the winding roller 12 to start to move, at the same time, the cloth A is continuously wound, the release roller 2 is continuously rotated, the cloth A and the film B are continuously released, the release of the cloth A is wound by the winding roller 12, and the film B is released, which causes the film between the second stripping roller 32 and the left feeding roller 51 to continuously increase, and the floating roller 43 reverses at the same time to continue to straighten the film, so as to ensure that the film will not be loose and deformed. The whole device runs continuously to feed a certain length of film to the feeding plate 7 and then stops. However, when the sensor 67 detects the film on the feeding plate 7, the cutting cylinder 63 will move the cutting knife 64 to press the film on the feeding plate 7 and cut the film, the cutting walking motor 62 starts to press the cutting knife 64 from one end to the other end to cut the film, after cutting is completed, the cutting cylinder 63 retreats, and the device stops running. Due to the adhesion of the film, although the film is cut, it will not fall off after being pressed tightly on the feeding plate 7 by the cutting knife 64, when the film on the feeding plate 7 is taken away, the device starts to run again, and the next action cycle is started, so as to realize automatic operation of the device and reduce the error of manual operation.
