Description

TECHNICAL FIELD

[0001] The present application relates to the putty powder processing technical field, especially relates to a detection device for putty powder processing. BACKGROUND

[0002] The bulk density of the putty powder needs to be detected after the putty powder processing is completed, the putty powder bulk density test (also called the bulk density test) is a basic test for evaluating its physical properties, mainly by measuring the mass of the putty powder in a unit volume, reflecting its particle loose degree, filling state and production consistency, and having important reference value for construction dosage estimation and product quality stability.

[0003] When the bulk density test is carried out, the putty powder is usually manually and slowly poured into a measuring cylinder, vibration or compaction (simulating natural accumulation state) needs to be avoided in the process, until the powder is slightly higher than the measuring cylinder scale line, but since the container containing the putty powder needs to be moved to make the putty powder uniformly distributed in the operation process, the top of the measuring cylinder is easily touched, causing the measuring cylinder to vibrate, and affecting the accuracy of the detection result. SUMMARY

[0004] The purpose of the present application is to provide a detection device for putty powder processing, which has the effect of improving the accuracy of the putty powder bulk density test result.

[0005] The above technical purpose of the present application is realized by the following technical scheme: including a workbench, a feeding hopper, a base provided on the workbench, and a detection support vertically provided on one side of the base, a first lifting lead screw and a second lifting lead screw are rotationally arranged on the side of the base away from the detection support in the vertical direction, a first lifting block is cooperatively arranged on the first lifting lead screw, a second lifting block is cooperatively arranged on the second lifting lead screw, a lifting plate is slidingly arranged between the first lifting block and the second lifting block in the horizontal direction, a first driving mechanism for driving the first lifting block and the second lifting block to synchronously lift is arranged on the detection support, a hopper-shaped discharging groove is formed in the lifting plate and matched with the bottom of the feeding hopper, a discharging pipe is communicatively arranged at the bottom of the feeding hopper in the vertical direction, a control valve is arranged on the discharging pipe, the discharging pipe movably passes through the discharging groove, and a second driving mechanism for driving the lifting plate to reciprocally move in the horizontal direction is arranged at the top end of the first lifting lead screw.

[0006] By adopting the above technical scheme, when the bulk density test of putty powder is needed, the putty powder is first put into the charging hopper, the charging hopper is put into the discharging groove, at this time the analytical balance and the measuring cylinder are placed on the workbench, the bottom of the discharging pipe is aligned with the measuring cylinder, then the first driving mechanism is opened, the first lifting block and the second lifting block are driven to descend synchronously, and then the lifting plate, the charging hopper and the discharging pipe are driven to descend, until the bottom end of the discharging pipe is close to but not in contact with the bottom of the measuring cylinder, then the control valve, the first driving mechanism and the second driving mechanism are opened, the first lifting lead screw and the second lifting lead screw are driven to rotate synchronously, the first lifting block and the second lifting block are driven to ascend synchronously, and then the charging hopper and the discharging pipe are slowly raised, in the process of slow rising of the discharging pipe, the second driving mechanism drives the lifting plate to reciprocate in the horizontal direction within a certain range, and then drives the charging hopper and the discharging pipe to reciprocate in the horizontal direction while slowly rising (it should be noted that by designing the reciprocating stroke of the lifting plate in the horizontal direction, it can be ensured that the discharging pipe will not be in contact with the inner wall of the measuring cylinder during reciprocation), finally when the bottom end of the discharging pipe moves to a scale line above the top of the measuring cylinder, the first driving mechanism and the second driving mechanism are closed, and the control valve is closed at the same time, then the bulk density of the putty powder can be calculated according to the measured data; therefore, by setting the lifting plate, the discharging pipe, the first driving mechanism and the like, the putty powder in the charging hopper is discharged during the slow rising and reciprocating movement in the horizontal direction of the discharging pipe, so that the putty powder can be evenly dropped into the measuring cylinder, and the wall collision phenomenon in the manual operation process is avoided, thereby improving the accuracy of the bulk density test result of the putty powder, and since the putty powder is discharged during the rising and horizontal movement of the charging hopper, it can ensure the smoothness and uniformity of the putty powder discharging process, thereby further improving the accuracy of the bulk density test result.

[0007] The further arrangement of the present application is that the second driving mechanism comprises a rotating disc horizontally arranged at the top end of the first lifting screw rod and a rotating rod arranged on the rotating disc in a vertical direction, the center axis of the rotating rod and the center axis of the rotating disc have a set distance, the rotating rod is horizontally provided with a rotating gear, the top end of the rotating rod is horizontally provided with a rotating plate, the detection support is provided with a positioning plate, the positioning plate is horizontally provided with a fixed plate, the fixed plate is horizontally provided with a circular fixed gear disc, the center axis of the fixed gear disc coincides with the center axis of the rotating disc, the rotating gear is engaged with the inner wall of the fixed gear disc, the end of the rotating plate is hingedly provided with a first push rod in a horizontal direction, the first push rod is movably arranged through the positioning plate, the end of the first push rod is vertically provided with a second push rod, the second push rod is located between the first lifting screw rod and the second lifting screw rod, and the second push rod is movably arranged through the lifting plate, when the first lifting screw rod rotates, the rotating rod can drive the rotating gear to rotate along the inner wall of the fixed gear disc, and the rotating plate can drive the first push rod to reciprocate in a horizontal direction.

[0008] By adopting the above technical scheme, the rotating disc, the rotating rod and the like are arranged, the rotating disc is driven to rotate when the first lifting screw rod rotates, the rotating rod and the rotating gear are driven to rotate around the center axis of the first lifting screw rod in the rotating process of the rotating disc, since the rotating gear is engaged with the inner wall of the fixed gear disc, the rotating gear is driven to revolve around the center axis of the first lifting screw rod while driving the rotating plate and the rotating rod to rotate, so as to drive the first push rod and the second push rod to reciprocate in a horizontal direction through the movement of the rotating plate, since the second push rod is movably arranged through the lifting plate, the lifting plate, the charging hopper and the discharging pipe are driven to reciprocate in a horizontal direction in the reciprocating process of the second push rod, so that the putty powder in the charging hopper can be uniformly dropped into the measuring cylinder, the putty powder in the measuring cylinder is prevented from being high in the middle and low on both sides, and the accuracy of the test result of the putty powder bulk density is improved.

Since the second push rod passes through the push block instead of the lifting plate, the second push rod will first abut against the first limiting block and then push the lifting plate to move away from the first lifting screw in the reciprocating movement of the push block in the horizontal direction. Then, the second push rod moves in the reverse direction to abut against the second limiting block and then push the lifting plate to move towards the first lifting screw. Since the movement distance of the second push rod in the horizontal direction is fixed, the movement distance of the second push rod in the horizontal direction can be adjusted by adjusting the positions of the first and second limiting blocks, that is, the movement distance of the feeding pipe in the horizontal direction is adjusted (it should be noted that the movement distance of the second push rod in the horizontal direction can meet the measurement requirements of large-capacity measuring cylinders, and the inner diameter of the large-capacity measuring cylinder is larger, so the movement distance of the feeding pipe in the horizontal direction needs to be reduced when a small-capacity measuring cylinder is replaced). Therefore, when the measuring cylinder of different capacity is replaced, the positions of the first and second limiting blocks can be adjusted through the first and second adjusting members, so that the detection device can meet the detection requirements of measuring cylinders of different capacity, thereby expanding the use range of the detection device.

[0020] By adopting the technical scheme, the first reset spring and the second reset spring are arranged, so that the push block is always attached to the first limiting block or the second limiting block under the elastic force of the first reset spring or the second reset spring during movement away from the first limiting block or the second limiting block, until the first reset spring or the second reset spring returns to the original length. Therefore, by arranging the first reset spring and the second reset spring, the lifting plate, the feeding pipe and the like can be kept in synchronous movement with the second push rod to the maximum extent, so that the reciprocating speed of the feeding pipe in the horizontal direction is more uniform, and the putty powder is more uniformly distributed in the measuring cylinder.

[0021] Further arrangement of the present application is that the lifting plate is symmetrically provided with a first positioning rod cooperating with the first reset spring in the horizontal direction, the first positioning rod is sequentially movably arranged through the first reset spring and the first lifting block, and the lifting plate is symmetrically provided with a second positioning rod cooperating with the second reset spring in the horizontal direction, the first positioning rod is sequentially movably arranged through the second reset spring and the second lifting block.

[0048] When the bulk density test of putty powder is needed, first put the putty powder into the charging hopper 2, and put the charging hopper 2 into the discharging groove 11. At this time, the analytical balance and the measuring cylinder are placed on the workbench 1, the bottom of the discharging pipe 37 is aligned with the measuring cylinder, then the driving motor 10b is turned on, the first synchronous rod 10a, the second synchronous rod 27, the first lifting lead screw 5 and the second lifting lead screw 6 are driven to rotate synchronously by the first synchronous belt 28, the second synchronous belt 29 and the third synchronous belt 30, the first lifting block 7 and the second lifting block 8 are driven to descend synchronously, and then the lifting plate 9, the charging hopper 2 and the discharging pipe 37 are driven to descend, until the bottom end of the discharging pipe 37 is close to but not in contact with the bottom of the measuring cylinder, then the control valve 12 and the driving motor 10b are turned on, the first lifting lead screw 5 and the second lifting lead screw 6 are driven to rotate synchronously, the first lifting block 7 and the second lifting block 8 are driven to ascend synchronously, and then the charging hopper 2 and the discharging pipe 37 are driven to ascend slowly. In the process of slow ascent of the discharging pipe 37, the first lifting lead screw 5 drives the rotating disc 13a to rotate, the rotating disc 13a drives the rotating rod 13b and the rotating gear 14 to rotate around the central axis of the first lifting lead screw 5 in the process of rotation of the rotating disc 13a, and at the same time, since the rotating gear 14 is engaged with the inner wall of the fixed tooth disc 18, the rotating gear 14 drives the rotating plate 15 and the rotating rod 13b to rotate around the central axis of the first lifting lead screw 5 while revolving around the central axis of the first lifting lead screw 5, and in the process of movement of the rotating plate 15, the first push rod 19 and the second push rod 20 are pushed to move back and forth in the horizontal direction, the second push rod 20 drives the lifting plate 9, the charging hopper 2 and the discharging pipe 37 to move back and forth in the horizontal direction in the process of reciprocating movement of the second push rod 20, so that the putty powder in the charging hopper 2 can fall evenly into the measuring cylinder, and therefore the charging hopper 2 and the discharging pipe 37 move back and forth in the horizontal direction while ascending slowly (it should be noted that by designing the stroke of the second push rod 20 moving back and forth in the horizontal direction, it can be ensured that the discharging pipe 37 will not be in contact with the inner wall of the measuring cylinder in the process of reciprocating movement), and finally when the bottom end of the discharging pipe 37 moves to a scale line above the top of the measuring cylinder, the driving motor 10b is turned off, and at the same time, the control valve 12 is turned off, and then the bulk density of the putty powder can be calculated according to the measured data; therefore, by arranging the lifting plate 9, the discharging pipe 37 and the first driving mechanism 10, the putty powder in the charging hopper 2 is discharged in the process of slow ascent and reciprocating movement in the horizontal direction of the discharging pipe 37, so that the putty powder can fall evenly into the measuring cylinder, and at the same time, the phenomenon of bumping in the process of manual operation is avoided, thereby improving the accuracy of the bulk density test result of the putty powder, and since the putty powder is discharged in the process of ascending and horizontal movement of the charging hopper 2, it can be ensured that the discharging process of the putty powder is smooth and uniform, thereby further improving the accuracy of the bulk density test result.

[0049] By setting the rotating disc 13a, rotating rod 13b and the like, the rotating disc 13a is driven to rotate while the first lifting lead screw 5 rotates, the rotating disc 13a drives the rotating rod 13b and the rotating gear 14 to rotate around the central axis of the first lifting lead screw 5 in the process of rotating, since the rotating gear 14 is engaged with the inner wall of the fixed gear plate 18, the rotating gear 14 drives the rotating plate 15 and the rotating rod 13b to rotate around the central axis of the first lifting lead screw 5 while revolving around the central axis, so as to push the first push rod 19 and the second push rod 20 to move back and forth in the horizontal direction through the movement of the rotating plate 15, since the second push rod 20 passes through the lifting plate 9, the second push rod 20 drives the lifting plate 9, the charging hopper 2 and the discharge pipe 37 to move back and forth in the horizontal direction in the process of reciprocating, so that the putty powder in the charging hopper 2 can fall evenly in the measuring cylinder, avoiding the situation that the putty powder in the measuring cylinder is high in the middle and low on both sides, thereby improving the accuracy of the test result of putty powder bulk density.

[0050] By rotatingly connecting the rotating disc 13a and the fixed plate 17, the stability of the rotating disc 13a in the process of rotating is improved, thereby improving the stability of the second driving mechanism 13.

[0051] By setting the moving hole 21, push block 22 and the like, the positions of the first limiting block 23 and the second limiting block 24 can be adjusted by the first adjusting part 25 and the second adjusting part 26, and the distance between the first limiting block 23 and the push block 22 and the distance between the second limiting block 24 and the push block 22 can be adjusted, since the second push rod 20 passes through the push block 22 instead of the lifting plate 9, the second push rod 20 will first abut against the first limiting block 23 and then push the lifting plate 9 to move away from the first lifting lead screw 5 in the process of driving the push block 22 to move back and forth in the horizontal direction, and then move in the opposite direction to abut against the second limiting block 24 and then push the lifting plate 9 to move towards the first lifting lead screw 5, since the movement distance of the second push rod 20 in the horizontal direction is fixed, the movement distance of the lifting plate 9 pushed by the second push rod 20 in the horizontal direction can be adjusted by adjusting the positions of the first limiting block 23 and the second limiting block 24, that is, the movement distance of the discharge pipe 37 in the horizontal direction can be adjusted (it should be noted that the movement distance of the second push rod 20 in the horizontal direction can meet the measurement requirements of large-capacity measuring cylinders, and when small-capacity measuring cylinders are replaced, the movement distance of the discharge pipe 37 in the horizontal direction needs to be reduced), therefore, when measuring cylinders of different capacities are replaced, the positions of the first limiting block 23 and the second limiting block 24 can be adjusted by the first adjusting part 25 and the second adjusting part 26, so that the detection device can meet the detection requirements of measuring cylinders of different capacities, thereby expanding the use range of the detection device.

[0052] By setting the first threaded rod 25a, the first connecting barrel 25b, etc., when the position of the first limiting block 23 needs to be adjusted, the first connecting barrel 25b is rotated to drive the first limiting block 23 to move close to or away from the movable push block 22, which is simple and convenient to operate.

[0053] By setting the second threaded rod 26a, the second connecting barrel 26b, etc., when the position of the second limiting block 24 needs to be adjusted, the second connecting barrel 26b is rotated to drive the second limiting block 24 to move close to or away from the movable push block 22, which is simple and convenient to operate.

[0054] By setting the first synchronous rod 10a, the second synchronous rod 27, etc., when the bulk density test of putty powder needs to be performed, the driving motor 10b is turned on to drive the first synchronous rod 10a, the second synchronous rod 27, the first lifting lead screw 5, and the second lifting lead screw 6 to rotate synchronously through the first synchronous belt 28, the second synchronous belt 29, and the third synchronous belt 30, which drives the first lifting block 7 and the second lifting block 8 to ascend synchronously, and further drives the lifting block, the charging hopper 2, and the discharging pipe 37 to ascend slowly. The first lifting lead screw 5 is rotated to drive the rotating disc 13a to rotate, which drives the second push rod 20, the lifting plate 9, etc. to move reciprocally along the horizontal direction. The structure is designed ingeniously, and the operation is simple and convenient.

[0055] By setting the first return spring 31 and the second return spring 32, the first limiting block 23 or the second limiting block 24 is always attached to the push block 22 under the elastic force of the first return spring 31 or the second return spring 32 during the process of moving away from the first limiting block 23 or the second limiting block 24, until the first return spring 31 or the second return spring 32 returns to the original length. Therefore, by setting the first return spring 31 and the second return spring 32, the lifting plate 9, the discharging pipe 37, etc. can be synchronized with the second push rod 20 to the greatest extent, so that the reciprocating speed of the discharging pipe 37 in the horizontal direction is more uniform, and the putty powder is distributed more uniformly in the measuring cylinder.

[0056] By setting the first positioning rod 33 and the second positioning rod 34, the stability of the first return spring 31 and the second return spring 32 during the movement process is increased, and the connection between the lifting plate 9 and the first lifting block 7 and the second lifting block 8 is increased, so that the movement process of the lifting plate 9, the charging hopper 2, and the discharging pipe 37 is more stable.

[0057] By setting the third positioning rod 36 and the positioning groove 35, the connection between the second push rod 20 and the detection support 4 is increased, so that the movement process of the second push rod 20 is more stable.
