DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings:

[0024] Referring to the accompanying drawings: the material stratification and interactive mixing device of this coating machine includes a barrel 1, a cover plate 11 is provided at the feed end of the barrel 1, and a barrel cover 12 is provided at the discharge end. A plurality of guide plates 2 located at high, middle, and low positions are provided in the barrel 1. The guide plates 2 are connected to a connecting component 3 provided on the inner wall of the barrel 1. The connecting component 3 includes an outer shell 31 and a connecting member 32. The outer shell 31 is provided on the barrel 1, and the connecting member 32 is rotatably provided in the outer shell 31 and connected to the guide plates 2, and the use angle of the guide plates 2 can be adjusted by rotating the connecting member 32. The principle of the present invention is that the guide plate 2 is in a spiral configuration, and its spiral direction is consistent with the mixing direction of the barrel 1. When the barrel 1 rotates, the guide plate 2 can transport the material near the feed port to the discharge port, thereby ensuring smooth discharge and preventing the mixed material from being blocked in the barrel 1. The high, middle, and low positions are set to achieve all-round cross-flow up and down, front and back, and improve the mixing rate of the materials. In particular, materials with different specific gravities will no longer be stratified during discharge. The connecting component 3 makes the guide plate 2 detachable, and the disassembly is to meet the production capacity requirements:

[0025] When the capacity is 50%-100%, the guide plates 2 at the three positions are not disassembled;

[0026] When the capacity is 25%-50%, remove the guide plate 2 at the high position;

[0027] When the production capacity is 10%-25%, the guide plates 2 at the high and middle positions are removed, that is, the contact between the guide plates 2 and the materials is reduced under low production capacity, so that the materials can quickly reach the discharge port under the rotation of the cylinder 1. At the same time, the connecting component 3 can also change the use angle of the guide plates 2 to adapt to the loading capacity of different materials.

[0028] A base plate 4 is provided at the bottom of the outer shell 31, and plug-ins 41 are provided at two symmetrical side walls of the base plate 4. The outer peripheral surface of the cylinder 1 is set to a grid-like configuration. The plug-in 41 is plug-in-matched with the grid of the cylinder 1 to prevent the connection component 3 from being separated from the cylinder 1. The area of ​​the base plate 4 is larger than the area of ​​the outer shell 31, so that the contact area with the cylinder 1 is large. The plug-in 41 is used to realize the assembly of the connection component 3 and the cylinder 1. Because the outer peripheral surface of the cylinder 1 is a grid configuration, such a configuration allows the dust to be separated from the cylinder 1 by the grid during the coating process, and the dust generated by the internal processing of the cylinder 1 can be quickly removed. The grid can also be plug-in-matched with the plug-in 41, so that the base plate 4 is stably set on the cylinder 1.

[0029] The plug-in 41 includes an extension plate 411 extending along the width direction of the bottom plate 4, and plug connectors 412 formed on the extension plate 411 and equidistantly distributed along the width direction. The plug connectors 412 are divided into a sliding section 4121 and a locking section 4122 along the assembly guide. The grid and the sliding section 4121 are clearance-fitted, and the locking section 4122 is interference-fitted. A through hole 4123 that simultaneously penetrates the extension plate 411 is provided in the plug connector 412. Such a configuration enables the plug-in 41 to have a plurality of plug connectors 412, and the corresponding number of plug-in 41 and the grid is also a plurality, thereby increasing the assembly stability of the bottom plate 4 and the cylinder 1. The clearance fit enables the plug connector 412 to be inserted into the cylinder 1. When the grid is formed, it can be moved along the assembly guide, and when it moves to the locking section 4122, it can fit with it, so that the plug connector 412 is locked in the grid to complete the assembly connection between the base plate 4 and the cylinder 1; such connection assembly does not require tools, nor does it require additional parts such as screws, etc., and is suitable for quick assembly and convenient assembly. The through hole 4123 is provided to make the plug connector 412 variable, that is, when it is fit, the locking section 4122 of the plug connector 412 can slightly concave inward after being subjected to force, so as to adapt to the size of the grid, while increasing the locking stability of the plug connector 412 and the grid, it also enables the base plate 4 to be stably fitted with the inner surface of the cylinder 1.

[0030] The matching gap between the plug connector 412 and the grid is gradually reduced along the assembly guide, so that the change of the gap width is linear, which makes the insertion process smoother and avoids the phenomenon of jamming in the middle of the connection assembly.

[0031] The housing 31 is provided with an installation cavity 311 for the connector 32 to be placed therein. The installation cavity 311 is provided with sockets 3111 symmetrically distributed on both sides of the housing 31, wherein one socket 3111 allows the guide plate 2 to enter the housing 31, and the other socket 3111 allows part of the guide plate 2 to pass through the housing 31 to achieve the combination of the guide plate 2 and the housing 31. The connector 32 has a slot 321 that is arranged through it. After the guide plate 2 enters the housing 31, it is combined with the connector 32 by plugging and fitting with the slot 321. The socket 3111 is provided with a limiting groove 31111 on the housing 31 that matches its configuration and serves to limit the adjustment angle of the guide plate 2. The guide plate 2 is located at The curved section in the middle and the straight sections on both sides of the curved section, the curved section is a sheet-like component, the straight sections are sheet-like components or cylindrical components, the straight sections pass through the shell 31 through the socket 3111 to be combined with the connecting member 32, and the arrangement of some straight sections passing through the shell 31 can increase the bonding strength between the guide plate 2 and the shell 31, the width of the socket 3111 is consistent with the width of the limiting groove 31111, and the width dimension of the guide plate 2 is smaller than the width dimension, so that the size difference can be used to provide space for adjusting the angle of the guide plate 2, the connecting member 32 is set as a spherical component, and the mounting cavity 311 is an arc-shaped configuration, so that the mounting cavity 311 matches the configuration of the connecting member 32, so that the connecting member 32 can rotate inside.

[0032] The installation cavity 311 is provided with an inlet 3112 on the shell 31, and a closing cover 5 is provided at the inlet 3112 for closing the inlet 3112 when the connecting member 32 is placed in the installation cavity 311. The closing cover 5 realizes its own connection or release with the shell 31 by rotation. The setting of the inlet 3112 makes the installation cavity 311 have a bullet-shaped configuration, that is, it has both an arc segment and a straight segment. The arc segment is used to cooperate with the connecting member 32, and the straight segment allows part of the connecting member 32 to be placed inside and also realizes connection with the closing cover 5. The closing cover 5 uses the inner cavity to allow part of the connecting member 32 to be placed inside, so that the closing cover 5 can provide lower support for the connecting member 32, so as to completely confine the connecting member 32 in the installation cavity 311.

[0033] The inlet 3112 is provided with a positioning slot 31121 on the housing 31 for quickly limiting the final assembly position of the closing cover 5 on the housing 31. The inner circumference of the positioning slot 31121 is provided with a locking member 6. The closing cover 5 is provided with a locked member 7. The locking member 6 enters the locked member 7 after the closing cover 5 is placed in the positioning slot 31121, and the locking member 6 and the locked member 7 are locked and combined by rotating the closing cover 5 to prevent the closing cover 5 from being separated from the housing 31. After the closing cover 5 is placed in the positioning slot 31121, it is only necessary to match the use positions of the locking member 6 and the locked member 7, and after the position matching is completed, the locking member 6 and the locked member 7 can be locked and combined by rotating, thereby completing the operation of installing the closing cover 5 on the housing 31, which is convenient and quick. In this embodiment, the closing cover 5 is T-shaped.

[0034] The locking piece 6 has multiple parts and is distributed in the circumferential direction of the inner peripheral surface of the positioning slot 31121. It is configured as a columnar component, and a locking socket 61 is provided on the outer peripheral surface of the columnar component, so that the closing cover 5 has multiple locking positions, which can increase the locking strength. The locking socket 61 is used to lock and combine with the locked piece 7, and the entrance end of the locking socket 61 exists on the rotation path of the closing cover 5, so that the locking piece 6 and the locked piece 7 can be locked and combined by rotation.

[0035] The number of locked members 7 matches the number of locking members 6, which include a first guide channel 71, a second guide channel 72, an end groove 73, and a locking plug 74 formed on the closing cover 5. The columnar member reaches the end groove 73 through the first guide channel 71 and the second guide channel 72, and the locking plug 74 is locked and combined with the locking socket 61 when reaching the end groove 73, so that the columnar member needs to pass through two sections of guide channels when reaching the end groove 73, and the first guide channel 71 and the second guide channel 72 are arranged vertically, which not only extends the length of the columnar member to reach the end groove 73, but also changes the path direction, so that when the locking combination of the locking plug 74 and the locking socket 61 fails accidentally, it can increase the difficulty of the columnar member to detach from the locked member 7. The locking plug 74 is arranged in the end groove 73, so that when the columnar member reaches the end groove 73, it can be locked and combined with the locking plug 74.

[0036] A screw 42 is provided at the center position of the bottom plate 4, and a screw hole 51 is provided at the center position of the closing cover 5, which is threadedly connected to the screw 42 and allows the screw 42 to enter the shell 31 and abut against the connecting piece 32. Such a setting realizes the assembly of the bottom plate 4 and the connecting component 3. The screw 42 is not only used as a connecting component, but also can be used as a limiting component. The screw 42 enters the shell 31 after threaded cooperation with the screw hole 51, and the spiral direction is consistent with the rotation direction of the closing cover 5 when closed, so as not to affect the locking of the closing cover 5. After entering the shell 31, the screw 42 abuts against the connecting piece 32, and the abutment strength affects the rotation smoothness of the connecting piece 32, that is, when it is necessary to adjust the use angle of the guide plate 2, the abutment strength between the screw 42 and the connecting piece 32 is reduced, and the abutment strength is increased to complete the angle adjustment, so as to prevent the connecting piece 32 from rotating by the increased abutment strength.
