Technical Field

[0001] This utility model relates to the technical field of material mixing, and in particular to a cylinder cover moving device for a material mixing system. Background Technology

[0002] A material mixing system refers to the operation of stirring a liquid to cause it to circulate in a certain way, thereby making the material uniformly mixed or accelerating physical and chemical processes.

[0003] In material mixing systems, the inner cylinder rotates continuously while the lid remains stationary during operation. A high dynamic sealing requirement exists between the inner cylinder and the lid. The lid needs to be lifted during subsequent material discharge and parts replacement / maintenance, necessitating a precise and convenient lid movement mechanism. However, existing material mixing systems suffer from low lid movement precision, affecting the seal between the lid and inner cylinder. The limited movement range also inconveniences subsequent material feeding, discharging, and parts replacement / maintenance. Furthermore, the system cannot detect the pressure after the lid and inner cylinder mate, compromising sealing effectiveness.

[0004] Therefore, there is an urgent need to design a cylinder cover moving structure that can not only effectively ensure the moving accuracy of the cylinder cover, but also detect the pressure after the cylinder cover and inner cylinder are in contact, thereby ensuring the sealing effect. At the same time, the larger moving range makes material discharge and parts maintenance and replacement more convenient. Utility Model Content

[0008] Optionally, the horizontal moving mechanism includes a drive component and a horizontal lead screw, the horizontal lead screw forming a horizontal track, the sliding block I being threadedly connected to the horizontal lead screw, and the drive component being used to drive the horizontal lead screw to rotate.

[0025] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0026] This utility model discloses a material mixing system cylinder cover moving device.

[0027] Reference Figure 1 and Figure 2 A material mixing system cylinder cover moving device includes a support platform 1, an inner cylinder 2 and a cylinder cover 3. The support platform 1 is installed on the inner cylinder 2 as a bearing base, and a stirring component is provided on the cylinder cover 3. The cylinder cover 3 is driven to move closer to or away from the inner cylinder 2 so that the stirring component provided on the cylinder cover 3 extends into or is removed from the inner cylinder 2.

[0028] In this embodiment, the support platform 1 has horizontal tracks. There are two horizontal tracks arranged along the width direction of the support platform 1. The two horizontal tracks are parallel to each other and parallel to the length direction of the support platform 1. The two horizontal tracks are far apart in the width direction of the support platform and close to the edge of the support platform on the corresponding side.

[0029] There are two sliding blocks I4 on the horizontal track, and the sliding blocks I4 are arranged in a one-to-one correspondence on the horizontal track.

[0030] Vertical rails are provided on the sliding block I4. There are two vertical rails on the slider 4. The vertical rails are arranged in a one-to-one correspondence on the slider 4. The two vertical rails are parallel to each other and parallel to the height direction of the support platform 1.

[0031] Sliding blocks II14 are provided on the vertical track. There are two sliders II14 on the vertical track, and the sliders II14 are arranged in a one-to-one correspondence on the vertical track.

[0032] The cylinder cover 3 is disposed on the sliding block II 14. Specifically, the cylinder cover 3 is located on both sides of the support platform 1 in the width direction and is respectively connected to the corresponding side of the sliding block II 14.

[0033] The vertical track is used for the cylinder cover 3 to slide in the vertical direction, and a vertical moving mechanism is provided on the vertical track to drive the cylinder cover 3 to move in the vertical direction.

[0034] The vertical moving mechanism consists of two sets, with the two sets of vertical moving mechanisms connected to the sliding blocks II 14 in a one-to-one correspondence. The sliding blocks II 14 are driven to move vertically along the corresponding vertical tracks. Specifically, the two sets of vertical moving mechanisms are controlled to operate synchronously using any existing control system or transmission system, so as to achieve the purpose of making the two sliding blocks II 14 move synchronously on the corresponding vertical tracks. Further details will not be elaborated here.

[0035] The two sliders II14, which are driven to run synchronously, cause the cylinder cover 3 to slide in the vertical direction, so that the cylinder cover moves closer to or away from the inner cylinder 2 in the vertical direction.

[0036] The support platform 1 is equipped with a horizontal moving mechanism for driving the sliding block I4 to slide in the horizontal direction.

[0037] The horizontal moving mechanism consists of two sets, with the two sets of horizontal moving mechanisms connected to the sliding blocks I4 in a one-to-one correspondence. The sliding blocks I4 are driven to move horizontally on the corresponding horizontal tracks. Specifically, the two sets of horizontal moving mechanisms are controlled to operate synchronously using any existing control system or transmission system, so as to achieve the purpose of making the two sliding blocks I4 move synchronously on the corresponding vertical tracks. This will not be elaborated further here.

[0038] The two sliding blocks I4, which are driven to run synchronously, cause the cylinder cover 3 to slide in the horizontal direction, so that the cylinder cover moves closer to or further away from the inner cylinder 2 in the horizontal direction.

[0039] In this embodiment, each horizontal movement mechanism includes a drive component 5 and a horizontal lead screw 6. The horizontal lead screw 6 forms a horizontal track, and a sliding block I4 is threadedly connected to the horizontal lead screw 6. The horizontal lead screw 6 and the drive component 1 are connected in a transmission relationship on the support platform 1. The drive component 5 adopts any type of servo motor in the prior art. The power output end of the servo motor is connected to the horizontal lead screw 6 to drive the horizontal lead screw 6 to rotate, thereby driving the sliding block I4 threadedly connected to the horizontal lead screw to slide along the length direction of the horizontal lead screw 6. By driving the horizontal lead screw 6 to rotate through the servo motor, the rotation of the horizontal lead screw 6 drives the sliding block I4 to move, thereby realizing the horizontal movement of the cylinder cover 3. In other embodiments, the horizontal movement mechanism can also be a belt transmission, gear belt transmission, cylinder or electric cylinder, etc., in the prior art, which will not be described in detail here.

[0040] In this embodiment, each vertical movement mechanism includes a driving component 2 8 and a vertical lead screw 9. The vertical lead screw 9 forms a vertical track, and a sliding block II 14 is threadedly connected to the vertical lead screw 9. The vertical lead screw 9 and the driving component 2 8 are configured in a transmission fit on the cover frame. The cover 3 is mounted on the vertical lead screw 9 via the sliding block II 14. The driving component 2 8 is used to drive the vertical lead screw 9 to rotate. The driving component 2 8 is any type of servo motor in the prior art. The power output end of the servo motor is connected to the vertical lead screw 9 to drive the vertical lead screw 9 to rotate, thereby driving the sliding block II 14 threadedly connected to the vertical lead screw 9 to slide along the length direction of the vertical lead screw 9. The servo motor drives the vertical lead screw 9 to rotate, and the rotation of the vertical lead screw 9 drives the cover 3 with the sliding block II 14 to move in the vertical direction. The vertical movement mechanism can drive the stirring assembly to completely leave the inner cylinder 2. In other embodiments, the vertical movement mechanism can also be a belt transmission, gear belt transmission, cylinder, or electric cylinder in the prior art, which will not be described in detail here.

[0041] The cylinder cover 3 is driven by horizontal and vertical moving mechanisms, which have high moving accuracy and ensure the sealing effect between the cylinder cover 3 and the inner cylinder 2. The large moving range makes material discharge and maintenance more convenient.

[0042] In this embodiment, the cylinder cover frame 16 is mounted on the slider I 4 via guide shafts 15. There are four guide shafts in total, with two guide shafts mounted on each slider I. The two guide shafts are spaced apart in the sliding direction of the corresponding slider I. The four guide shafts 15 are parallel to each other in the height direction and are distributed in a rectangular shape in the vertical projection to support the cylinder cover frame 16. The cylinder cover 3 is correspondingly mounted on the guide shafts via any of the existing bearings suitable for this solution. The inner ring of the bearing is slidably connected to the guide shaft, and the outer ring is fixedly connected to the cylinder cover 3. There are four bearings 17, which are arranged in a one-to-one correspondence on the guide shafts and connected to the cylinder cover 3, serving to guide the cylinder cover, ensuring the stable sliding of the slider II and improving the operational stability.

[0043] To further improve the accuracy of the lifting and lowering of the cover 3, this embodiment also includes a lifting position sensor 10, which is used to detect the vertical movement position of the cover 3. The lifting position sensor 10 can be an infrared sensor or a displacement sensor. In this embodiment, an infrared sensor is used. The lifting position sensor 10 includes a lifting position sensor installed on the cover frame 16 and a lowering position sensor installed on the cover 3. When the infrared sensor on the cover frame 16 receives a signal from the lifting position sensor 10, it indicates that the cover has been lifted to the correct position, and the operation of the drive component 8 is stopped.

[0044] To further improve the accuracy of the horizontal movement of the cylinder cover 3, this embodiment also includes a horizontal position sensor 7, which is used to detect the horizontal position of the cylinder cover 3. The horizontal position sensor 7 includes two sensors disposed at both ends of the horizontal lead screw 6. The horizontal position sensor 7 can be an infrared sensor or a displacement sensor. In this embodiment, the horizontal position sensor 7 uses an infrared sensor. When the infrared sensor detects that the infrared light is blocked, it indicates that the movement is in place, the servo motor stops running, and the cylinder cover 3 stops moving.

[0045] In order to improve the tightness of the connection between the cover 3 and the inner cylinder 2, a pressure sensor 11 is provided on the cover 3. The pressure sensor 11 is used to detect the pressure value between the cover 3 and the inner cylinder 2. The pressure sensor 11 displays the pressure between the cover 3 and the inner cylinder 2, reflecting the sealing status between the inner cylinder 2 and the cover 3.

[0046] It also includes two horizontal positioning electric cylinders 12, which are arranged in a one-to-one correspondence with the sliding block I4, and the horizontal positioning electric cylinders 12 are located on the outer side of the corresponding sliding block I4. The two sets of horizontal positioning electric cylinders 12 are controlled to operate synchronously using any existing control system, so as to make the piston rods of the two sets of horizontal positioning electric cylinders 12 extend or retract synchronously on the corresponding side, which will not be described in detail here.

[0047] The support platform 1 is provided with multiple horizontal positioning blocks 13 at intervals along the length of the horizontal track, and the multiple horizontal positioning blocks 13 are located on the outer side of the corresponding side of the horizontal track.

[0048] In this scheme, four horizontal positioning blocks 13 are provided. Every two horizontal positioning blocks 13 located on the outer side of the same horizontal track form a group, and a total of two groups of horizontal positioning blocks are provided. Each group of horizontal positioning blocks cooperates with the horizontal positioning electric cylinder on that side. Specifically, taking the single-side cooperation structure as an example, in one group of horizontal positioning blocks 13, one horizontal positioning block 13 is located at the opening away from the inner cylinder 2. When the horizontal positioning electric cylinder 12 on that side is used to cooperate with the horizontal positioning block 13, it means that the opening of the cylinder cover 3 and the inner cylinder 2 are completely misaligned. The other one is located at the opening of the inner cylinder 2. When the horizontal positioning electric cylinder 12 on that side is used to cooperate with the horizontal positioning block 13, it means that the opening of the cylinder cover 3 and the inner cylinder 2 are completely aligned. The horizontal positioning electric cylinder 12 located on the same side is used to cooperate with the group of horizontal positioning blocks 13 on that side. The horizontal positioning block 13 has a through hole for the piston rod of the horizontal positioning electric cylinder 12 to pass through, which is used to restrict the horizontal movement of the cylinder cover 3 and complete the horizontal position locking.

[0049] In this embodiment, a control system is also included. The control system adopts a PLC of the prior art. The control system is electrically connected to the first drive component 5, the second drive component 8, the pressure sensor 11, the horizontal positioning electric cylinder 12, the lifting position sensor 10, and the horizontal position sensor 7 of the prior art. It is used to control the opening and closing of the corresponding electrical components or to receive signals, such as receiving the pressure value of the pressure sensor 11. A pressure threshold is preset in the control system. The pressure threshold is a parameter value that meets the sealing requirements. When the received pressure value is within the pressure threshold, it indicates that a seal is formed between the cylinder cover 3 and the inner cylinder 2. At this time, the movement of the second drive component 8 is stopped.

[0050] The specific implementation method is as follows: The vertical lead screw 9 driven by the servo motor lifts the cylinder cover 3 upwards, and the lifting position sensor 10 determines the lifting height. At this time, the relevant stirring components extending into the inner cylinder 2 on the cylinder cover 3 have completely detached from the inner cylinder 2. Then, the horizontal lead screw 6 driven by the servo motor drags the cylinder cover 3 to one side, and the horizontal position sensor 7 determines the moving position. Then, the horizontal positioning electric cylinder 12 and the horizontal positioning block 13 engage through holes to complete the horizontal position locking. At this time, the cylinder cover 3 is completely detached from the inner cylinder 2, which facilitates the addition of premixed materials and the maintenance and replacement of related parts. After completion, the servo motor first drives the horizontal lead screw 6 to the top of the inner cylinder 2. On the other side, the horizontal position sensor 7 determines the position of the cover 3, ensuring the fit between the cover 3 and the inner cylinder 2. Then, the servo motor drives the vertical screw 9 to drag the cover 3 down. The lifting position sensor 10 determines the descent distance of the cover 3, ensuring the fit between the cover 3 and the inner cylinder 2. The pressure sensor 11 displays the pressure between the cover 3 and the inner cylinder 2, reflecting the sealing status between the inner cylinder 2 and the cover 3. The servo motor drives the vertical screw 9 to lift or press the cover 3 so that the pressure reaches the parameter value that meets the sealing requirements. After the pressure and position are determined, the horizontal positioning electric cylinder 12 extends and fits with the horizontal positioning block 13 at one end of the inner cylinder 2 through the hole to complete the horizontal position locking.
