Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of process equipment, in particular to a coating device for flowable material. BACKGROUND

[0002] At present, there is a coating device for flowable material, which comprises a container containing flowable material, a coating roller rotatingly connected to the container and contacting the flowable material in the container, and a support frame. When the angle position of the coating roller needs to be changed, the container is manually rotated around the support frame to move the coating roller.

[0003] Since the material has high adhesion, in order to prevent the material particles from adhering to the steel belt and being unable to be scraped off, a certain amount of silicon oil emulsion needs to be applied to the surface of the steel belt by means of the coating device. This liquid is called a release agent. When the device is in a working state, the coating roller contacts the rotating drum, and the rotating drum drives the coating roller to rotate together. When the steel belt passes through the area between the rotating drum and the coating roller, the surface of the steel belt will be coated with a layer of release agent. The main purpose is to make the solidified material particles not adhere to the steel belt and be easy to release.

[0004] The previously sold granulator relies on manual control on the coating device, but the device has certain requirements for the opening time. Too early opening will cause the release agent to enter the bin through the steel belt, affecting the product quality. Too late opening will cause the material particles to adhere to the surface of the steel belt and be unable to be smoothly scraped off by the scraper. Manual operation is prone to errors, affecting the production capacity. SUMMARY

[0005] The purpose of the present application is to provide a coating device for flowable material, which uses an automatic mode to drive the container to rotate around the support frame to change the position of the coating roller.

[0006] The purpose of the present application is achieved by a coating device for flowable material, which comprises a container containing flowable material, a coating roller rotatingly connected to the container and contacting the flowable material in the container, and a support frame. The device further comprises at least one set of driving mechanism for automatically driving the container to rotate up and down around the support frame.

[0007] The driving mechanism comprises:

[0008] a driving cylinder, one end of which is rotatingly connected to the support frame;

[0009] a swing arm, one end of which is rotatingly connected to the driving cylinder and the other end of which is rotatingly connected to the container;

[0010] A fulcrum base is fixedly connected to the frame, and the other end of the swing arm is rotatably connected to the fulcrum base and constitutes a fulcrum for the up-down swing rotation of the swing arm, and the fulcrum of the swing arm is above the container.

[0011] A traction link is rotatably connected to the swing arm at the upper end of the link and movably connected to a connecting structure fixedly arranged on the container at the lower end of the link.

[0012] Further, the lower end of the traction link is connected to a connecting sleeve, and the connecting structure of the container comprises a connecting rod fixedly connected to the container, the connecting sleeve is a round sleeve, and the connecting rod is a cylindrical rod, and the connecting sleeve is rotatably sleeved with the connecting rod.

[0013] Further, the traction link is adjustably connected with an adjusting rod, and the adjusting rod is connected with the connecting sleeve.

[0014] Further, the adjusting rod is an adjusting screw rod which constitutes a part of the traction link, the adjusting screw rod is sleeved with an adjusting nut, and the traction link is provided with a supporting plate which supports the adjusting nut and accommodates the adjusting screw rod.

[0015] Further, the fulcrum base is provided with a swing limiting protrusion for limiting the rotation angle limit position of the swing arm.

[0016] Further, when the swing arm is rotated to the upright state, the piston rod of the driving cylinder is extended to make the swing arm laterally abut against the swing limiting protrusion.

[0017] Further, the fulcrum base is provided as a vertical plate structure, the fulcrum base has a circular arc edge which is concentric with the fulcrum of the swing arm, and the swing limiting protrusion is connected with the circular arc edge.

[0018] Further, the connecting rod is fixedly arranged at the bottom of the container.

[0019] Further, the driving cylinder is a driving air cylinder, and is provided with an air cylinder supporting hinge base which is fixedly connected to the frame, the cylinder barrel of the driving air cylinder is rotatably connected to the air cylinder supporting hinge base, and the piston rod of the driving air cylinder is rotatably connected to the swing arm.

[0020] Further, the axis of the coating roller horizontally extends and is parallel to the axis of the upper rotating roller and the axis of the fulcrum rotating shaft, and when the swing arm is rotated to the upright state, the rotating connection points at the upper and lower ends of the swing arm and the rotating connection points at the upper and lower ends of the traction link are located on the same vertical line based on the axial view of the coating roller, so that the center of the coating roller and the center of the upper rotating roller are located on the same vertical line.

[0021] The present application has the following advantages:

[0022] 1. The container is rotated axially around the fulcrum to change the position of the coating roller in an automatic manner. When the coating roller is rotated upward, the driving cylinder drives the swing arm to rotate upward around its fulcrum, thereby pulling the container upward through the traction link, driving the container to rotate axially around the fulcrum, and at the same time, the coating roller also moves upward, so that the coating roller moves to the predetermined position;

[0023] 2. It has good self-locking performance.

[0026] The present application will be further described below in combination with the drawings and specific embodiments. The present embodiment is mainly for the occasion of coating release agent. Considering that there are several types of flowable substances, the present application can be applied to other occasions of coating flowable substances, and therefore is not limited in the present application.

[0027] As shown in Figure 1 , 2 , a coating device for flowable substances is used for coating release agent on a steel strip, which comprises a container 9 containing flowable substances (i.e. release agent mentioned in the present embodiment) and rotatingly connected to a rack through a fulcrum rotating shaft 10 at one end, a coating roller 11 rotatingly connected to the container 9 and contacting the flowable substances in the container 9 with its roller surface, and at least one set of driving mechanism for driving the container 9 to rotate upward and downward around the fulcrum rotating shaft 10. Such driving mechanism can be provided with one or two sets.

[0028] The above-mentioned driving mechanism comprises:

[0029] a driving cylinder, which is provided as a driving air cylinder 1 in the present embodiment. The driving cylinder can be a hydraulic cylinder, an electric cylinder, etc. The driving air cylinder 1 is rotatably connected to the rack at one end;

[0030] The swing arm 2 is rotatably connected to the other end of the driving cylinder 1, and is provided with a cylinder support hinge base 13 fixedly connected to the frame. The cylinder barrel of the driving cylinder 1 is rotatably connected to the cylinder support hinge base 13, and the piston rod of the driving cylinder 1 is rotatably connected to the swing arm 2.

[0031] The fulcrum base 8 fixedly connected to the frame above the container 9 is rotatably connected to the other end of the swing arm 2, and the rotatable connection point constitutes the fulcrum of the up-down swing rotation of the swing arm 2. The fulcrum of the swing arm 2 is above the container 9.

[0032] The traction connecting rod 3 is rotatably connected to the swing arm 2 at the upper end of the rod body, and is movably connected to the connecting structure fixedly arranged on the container 9 at the lower end.

[0033] The lower end of the traction connecting rod 3 is connected to the connecting sleeve 5, and the connecting structure of the container 9 includes a connecting rod 7 fixedly connected to the container 9, which is arranged at the bottom of the container 9 and at the free end position of the container 9. Therefore, the container 9 is equivalent to a mechanism that rotates around the fulcrum rotation shaft 10 for up-down swing. The connecting sleeve 5 is a round sleeve, the connecting rod 7 is a cylindrical rod, and the connecting sleeve 5 is rotatably sleeved with the connecting rod 7.

[0034] As one of the preferred schemes of the embodiment, the above-mentioned traction connecting rod 3 is adjustably connected with an adjusting rod, and is connected with the connecting sleeve 5 through the adjusting rod. The adjusting rod is arranged as an adjusting screw 4 constituting a part of the traction connecting rod 3, the adjusting screw 4 is sleeved with an adjusting nut 6, and the traction connecting rod 3 is provided with a support plate 3a supporting the adjusting nut 6 and accommodating the adjusting screw 4. Through such structure optimization design, the length of the traction connecting rod 3 can be adjusted. During adjustment, only the adjusting nut 6 is twisted, and the adjusting screw 4 is axially offset relative to the traction connecting rod 3 through thread cooperation, so that the length of the traction connecting rod 3 can be adjusted.

[0035] As one of the preferred schemes of the embodiment, the above-mentioned fulcrum base 8 is provided with a swing limiting protrusion 8a for limiting the rotation angle limit position of the swing arm 2. When the swing arm 2 is rotated to the upright state, the piston rod of the driving cylinder 1 is extended to make the swing arm 2 laterally abut against the swing limiting protrusion 8a.

[0036] As one of the preferred schemes of the embodiment, the above-mentioned fulcrum base 8 is arranged as a vertical plate structure, the fulcrum base 8 has a circular arc edge concentric with the fulcrum of the swing arm 2, and the swing limiting protrusion 8a is connected with the circular arc edge.

[0037] As one of the preferred embodiments of the present application, the axis of the coating roller 11 extends horizontally and is parallel to the axis of the upper rotating roller and the axis of the fulcrum rotating shaft 10. When the swing arm 2 is rotated to the upright state, the rotating connection points at the upper and lower ends of the swing arm 2 and the rotating connection points at the upper and lower ends of the traction link 3 are on the same vertical line (the axis of the adjusting screw 4 and the axis of the adjusting nut 6 are on the vertical line) based on the axial view of the coating roller 11, so that the center of the coating roller 11 and the center of the upper rotating drum 12 are on the same vertical line, and the roller surface of the coating roller 11 contacts the outer peripheral wall of the rotating drum 12 upward.

[0038] In combination Figure 1 , 2 , when the coating roller 11 is driven to rotate upward, the swing arm 2 is driven to rotate upward around the fulcrum by the driving cylinder 1, so that the container 9 is pulled upward by the traction link 3, the container 9 is driven to rotate upward around the fulcrum rotating shaft 10, and the coating roller 11 also moves upward, so that the coating roller 11 moves to the predetermined position. In the present embodiment, the center of the coating roller 11 and the center of the upper rotating drum 12 are on the same vertical line (the axes of the two form a vertical plane) based on the axial view of the coating roller 11, which means that the coating roller 11 is vertically attached to the rotating drum 12. Therefore, the roller surface of the coating roller 11 does not have or basically has no horizontal component force when it contacts the outer peripheral wall of the rotating drum 12 upward. If the center of the coating roller 11 and the center of the upper rotating drum 12 are not on the same vertical line, the coating roller 11 will exert a horizontal component force on the rotating drum 12 when it contacts the rotating drum 12 upward. Since the rotating drum 12 can be finely adjusted in the horizontal direction, the force is likely to be inclined, which further causes the steel belt to deviate.

[0039] As shown in Figure 1 , in order to fully achieve the technical effect that the center of the coating roller 11 and the center of the upper rotating drum 12 are on the same vertical line based on the axial view of the coating roller 11, when the swing arm 2 is rotated to the upright state, the piston rod of the driving cylinder 1 is extended to make the swing arm 2 laterally abut against the swing limiting protrusion 8a, the swing limiting protrusion 8a laterally abuts against the swing arm 2 to prevent the swing arm 2 from rotating out of position, so as to maintain the upright position of the swing arm 2. At this time, the rotating connection points at the upper and lower ends of the swing arm 2 and the rotating connection points at the upper and lower ends of the traction link 3 are on the same vertical line based on the axial view of the coating roller 11, that is, the upper rotating connection point of the swing arm 2, the upper rotating connection point of the traction link 3, the fulcrum of the swing arm 2, and the center of the connecting sleeve 5 form a vertical line from top to bottom, and the axes of the adjusting screw 4 and the adjusting nut 6 are also on the vertical line, thereby generating a self-locking effect and forming a stable support foundation, so that the center of the coating roller 11 and the center of the upper rotating drum 12 are on the same vertical line, the support effect in the vertical direction is in a stable state, a self-locking effect is formed, and the position of the coating roller 11 is locked.

[0040] In order to avoid the error of manual operation, the device is upgraded and can automatically adjust through the PLC control cylinder according to the actual production situation, so that the whole release agent system is in working state or non-working state, and the product quality is ensured.

[0041] The above are preferred embodiments of the present application, and various transformations or improvements can be made by those skilled in the art on the basis of the above, and these transformations or improvements shall belong to the protection scope of the present application without departing from the general concept of the present application.
