Description

Technical Field

[0001] The invention relates to the technical field of dynamic inspection and calibration, in particular to a dynamic inspection and calibration device for a quantitative packaging machine. Background Art

[0002] Quantitative packaging machine is a kind of equipment used for the separation and processing system of constant small packages, mainly used for the packaging process of automatic feeding, filling and bagging; quantitative packaging machine is widely used in many industries, including quantitative weighing and packaging of granular and powder materials in grain, feed, fertilizer, chemical, building materials and other industries. It has the characteristics of high measurement accuracy, fast filling speed and high degree of automation. It can be matched with conveyors, heat sealing machines and other equipment to form a continuous packaging production line to complete the procedures of weighing, sealing and conveying materials.

[0003] When the quantitative packaging machine is performing quantitative filling of liquid, the system will inject a certain amount of liquid into the container according to the set value. This quantity only means that the amount of liquid flowing out of the quantitative packaging machine's discharge port is constant. Due to the tension of the liquid, some residual liquid will hang on the discharge port; this will cause the amount of liquid filled this time to be too small; at the same time, it may also merge with the subsequent filling liquid, making the subsequent filling amount of liquid too large; when the filling amount deviates too much from the set value, it will affect the quality of the product, and in severe cases it will make the production cost difficult to control; therefore, it is necessary to inspect the products packaged by the quantitative packaging machine; static batch inspection is often used for production control.

[0004] Static batch inspection means that after the quantitative packaging machine has been working for a period of time, the products within a time node are selected for unified weighing, and the average value is compared with the set value, and the packaging machine is debugged according to the comparison result; although this method can improve the inspection efficiency, the quantitative packaging machine operates in real time; the timeliness of the inspection results is not high; and collision and shaking during the unified weighing process may cause the liquid in the container to leak out, affecting the inspection results, thereby affecting the subsequent debugging of the quantitative packaging machine.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0031] See also Figure 1 to Figure 11 In an embodiment of the present invention, a dynamic inspection and calibration device for a quantitative packaging machine includes a frame 1; and a conveyor belt 2 rotatably mounted on the frame 1 for conveying a container 18; A pressure plate 14 is provided at one end of the conveyor belt 2; a gravity sensor module 17 is provided on the pressure plate 14; A conveying mechanism is provided between the conveyor belt 2 and the pressure plate 14; the conveying mechanism comprises two symmetrically arranged conveying plates 4; the conveying plates 4 can make reciprocating arc movements between the conveyor belt 2 and the pressure plate 14; a clamping mechanism is provided on the conveying plates 4; When the clamping mechanism clamps the container 18 on the conveyor belt 2, the transmission mechanism can drive the transmission plate 4 to move from the conveyor belt 2 to the pressure plate 14; and when the clamping sub-mechanism releases the container 18 on the pressure plate 14, the transmission mechanism can drive the transmission plate 4 to move from the pressure plate 14 to the conveyor belt 2.

[0032] Taking the embodiment combining all the features recorded in this application as an example, when in use, the discharge port of the quantitative packaging machine is arranged above the end of the conveyor belt 2 away from the pressure plate 14, and can inject a certain amount of product into the container 18; after the injection is completed, the conveyor belt 2 transports it toward the pressure plate 14.

[0033] When the quantitative packaging machine is pouring products into a container 18, the previous container 18 that has been filled is transported to the end of the conveyor belt 2 close to the pressure plate 14; when the quantitative packaging machine is pouring products, the clamping mechanism will clamp the previous container 18 that has been filled; and after the clamping mechanism is stably clamped, the delivery mechanism will operate to drive the transmission plate 4 to move in an arc from the conveyor belt 2 toward the pressure plate 14, so as to drive the container 18 clamped by the clamping mechanism to move toward the pressure plate 14; and during the movement, the transmission plate 4 always remains parallel to the pressure plate 14, so as to prevent the container 18 from overturning or shaking during the transmission process, thereby avoiding product leakage and causing deviations in subsequent weight detection results.

[0034] After the conveying mechanism drives the conveying plate 4 to reach the position of the pressure plate 14, that is, after the container 18 is stably in contact with the pressure plate 14, the clamping mechanism will release the container 18; after the clamping mechanism performs the releasing action, the conveying mechanism will drive the conveying plate 4 to move with the pressure plate 14 toward the conveyor belt 2, so as to facilitate the clamping mechanism to clamp the next container 18.

[0035] When the transfer plate 4 reaches the position of the conveyor belt 2 , the conveyor belt 2 has already transported another container 18 containing products to the side of the conveyor belt 2 close to the pressure plate 14 .

[0036] When the container 18 containing the product is on the pressure plate 14, the gravity sensor module 17 will detect the gravity change on the pressure plate 14, and compare the gravity change value with the standard value set by the system. If the deviation is large, the system will sound an alarm to remind the operator to adjust the quantitative packaging machine; after that, the operator moves the upper container 18 of the pressure plate 14 away.

[0037] The gravity sensor module 17 can detect the weight change on the pressure plate 14 more accurately; the clamping mechanism and the conveying mechanism alternately act and cooperate with each other, so that the container 18 can be conveyed more smoothly, which can avoid product leakage due to external reasons such as shaking and tilting during the conveying process, and can effectively improve the packaging efficiency of the quantitative packaging machine, avoid frequent debugging of the quantitative packaging machine due to detection errors, and indirectly increase the service life of the quantitative packaging machine; through the dynamic inspection and calibration method, unqualified products can be dealt with in time, and the quantitative packaging machine can be debugged in time according to the detection results, so as to improve the qualified rate of the products.

[0038] In another embodiment of the present invention, a fixing plate 15 is fixedly installed on the frame 1, and the fixing plate 15 is slidably connected to the pressure plate 14, and a detection spring 16 is arranged between the pressure plate 14 and the fixing plate 15; the two ends of the detection spring 16 respectively contact with the pressure plate 14 and the fixing plate 15; the gravity sensor module 17 is fixedly installed on the fixing plate 15.

[0039] Taking the embodiment of the combination of all the features recorded in this application as an example, when the container 18 containing the product is placed stably on the pressure plate 14, its gravity will act on the pressure plate 14, so that the pressure plate 14 is close to the fixed plate 15, compressing the detection spring 16; and the greater the weight of the container 18, the closer the pressure plate 14 is to the fixed plate 15, and the greater the compression of the detection spring 16, and vice versa. The gravity sensor module 17 can detect the position change of the pressure plate 14, and calculate the weight of the container 18, and compare the gravity change value with the standard value set by the system. If the deviation is large, the system will issue an alarm to remind the operator to adjust the quantitative packaging machine; then, the operator moves the upper container 18 of the pressure plate 14 away; after the container 18 is moved away from the pressure plate 14, under the elastic force of the detection spring 16, the pressure plate 14 will move away from the fixed plate 15 to complete the reset.

[0040] In another embodiment of the present invention, a bracket 3 is fixedly installed on the frame body 1; a motor 5 is fixedly installed on the bracket 3; a driving pulley 501 is fixedly connected to the output end of the motor 5, and a first rotating shaft 6 is rotatably installed on the bracket 3; a first pulley 601 is fixedly installed on the first rotating shaft 6; the first pulley 601 is connected to the driving pulley 501 by a belt; first clamping pulleys 602 are fixedly installed at both ends of the first rotating shaft 6; and a first transmission pulley 603 is fixedly installed on one end of the first rotating shaft 6.

[0041] Taking the embodiment of the combination of all the features recorded in this application as an example, when the quantitative packaging machine is started, a control signal is sent to start the motor 5. The motor 5 drives the driving pulley 501 to rotate, thereby driving the first pulley 601 to rotate through the belt, thereby driving the first rotating shaft 6 to rotate; the rotating first rotating shaft 6 drives the first clamping pulley 602 and the first conveying pulley 603 to rotate.

[0042] The first clamping pulley 602 is connected to the clamping mechanism; the first conveying pulley 603 is connected to the conveying mechanism; therefore, when the motor 5 is in motion, it can drive the clamping mechanism and the conveying mechanism to move, so as to drive the clamping mechanism and the conveying mechanism to move and cooperate with each other alternately, thereby realizing a relatively stable conveying container 18, which can avoid product leakage due to external reasons such as shaking and tilting during the conveying process, can effectively improve the packaging efficiency of the quantitative packaging machine, avoid frequent debugging of the quantitative packaging machine due to detection errors, and indirectly increase the service life of the quantitative packaging machine.

[0043] In another embodiment of the present invention, the clamping mechanism includes a clamping shaft 7 rotatably mounted on the conveying plate 4, a second clamping pulley 701 and a protrusion 702 are fixedly mounted on the clamping shaft 7, and the second clamping pulley 701 is connected to the first clamping pulley 602 by a belt; a connecting plate 8 is provided on the conveying plate 4; a sliding rod 801 slidably engaged with the conveying plate 4 is fixedly mounted on the connecting plate 8; a clamping sleeve 9 slidably connected to the clamping shaft 7 is fixedly mounted on the connecting plate 8; a matching groove slidably engaged with the protrusion 702 is opened in the clamping sleeve 9; and a clamping plate 10 is provided on the connecting plate 8.

[0044] In another embodiment of the present invention, the mating groove includes a first oblique groove 901, a first flat groove 902, a second oblique groove 903 and a second flat groove 904; wherein; one end of the first oblique groove 901 is connected to the first flat groove 902; the other end of the first flat groove 902 is connected to one end of the second oblique groove 903; the other end of the second oblique groove 903 is connected to one end of the second flat groove 904; the other end of the second flat groove 904 is connected to the other end of the first oblique groove 901.

[0045] Taking the embodiment combining all the features described in this application as an example, when the first clamping pulley 602 rotates, the second clamping pulley 701 is driven to rotate through the belt, thereby driving the clamping shaft 7 to rotate. The rotating clamping shaft 7 drives the protrusion 702 to rotate synchronously.

[0046] In the initial position, the conveying plate 4 is located on the conveyor belt 2, and the protrusion 702 is located at the connection end of the first flat groove 902 and the second inclined groove 903. When the protrusion 702 rotates, the protrusion 702 will slide in the second inclined groove 903 toward the connection end of the second inclined groove 903 and the second flat groove 904. At this time, under the mutual interference of the protrusion 702 and the second inclined groove 903, the clamping sleeve 9 will gradually move away from the conveying plate 4, so as to drive the connecting plate 8 away from the conveying plate 4, and the sliding rod 801 will slide with the conveying plate 4, so as to drive the two clamping plates 10 to approach each other to clamp the container 18.

[0047] When the protrusion 702 slides in the second flat groove 904 toward the connecting end of the second flat groove 904 and the first inclined groove 901 , the position of the clamping sleeve 9 remains unchanged, so that the two clamping plates 10 can maintain a constant distance to maintain the clamping state of the container 18 .

[0048] When the protrusion 702 slides in the first inclined groove 901 toward the connection end of the first inclined groove 901 and the first flat groove 902, the protrusion 702 will drive the clamping sleeve 9 to move closer to the conveying plate 4 under the resistance of the first inclined groove 901, thereby driving the connecting plate 8 to move closer to the conveying plate 4, thereby driving the two clamping plates 10 to move away from each other to release the container 18; When the protrusion 702 slides in the first flat groove 902 toward the connecting end of the first flat groove 902 and the second inclined groove 903, the position of the clamping sleeve 9 remains unchanged, so that the distance between the two clamping plates 10 remains unchanged, so as to avoid collision with the container 18 on the conveyor belt 2 during transportation.

[0049] By alternately moving and cooperating with the clamping mechanism and the conveying mechanism, the container 18 can be conveyed more smoothly, which can avoid leakage of products due to external reasons such as shaking and tilting during the conveying process, effectively improve the packaging efficiency of the quantitative packaging machine, avoid frequent debugging of the quantitative packaging machine due to detection errors, and indirectly increase the service life of the quantitative packaging machine. In another embodiment of the present invention, a telescopic column 1001 is fixedly installed on the splint 10; a telescopic sleeve 802 slidably engaged with the telescopic column 1001 is fixedly installed on the connecting plate 8; a buffer spring 11 is arranged in the telescopic sleeve 802; and both ends of the buffer spring 11 respectively contact the telescopic column 1001 and the connecting plate 8.

[0050] Taking the embodiment combining all the features recorded in the present application as an example, when in use, when the two splints 10 approach each other, the splint 10 will first collide with the container 18, and then the connecting plate 8 will still move away from the conveying plate 4 to reduce the distance between the connecting plate 8 and the splint 10. At this time, the telescopic column 1001 will slide inward in the telescopic sleeve 802 to compress the buffer spring 11; through the elastic force of the buffer spring 11, the force between the splint 10 and the container 18 is increased to prevent the container 18 from falling off during the conveying process, and to prevent the container 18 from being deformed due to excessive clamping force during the clamping process.

[0051] In another embodiment of the present invention, the conveying mechanism includes a conveying shaft 12 rotatably mounted on the bracket 3; a second conveying pulley 1201 is fixedly mounted on the conveying shaft 12, and the second conveying pulley 1201 is connected to the first conveying pulley 603 by a belt; a turntable 13 is fixedly mounted on the conveying shaft 12; rotating rods 301 are rotatably mounted at both ends of the bracket 3; connecting rods 302 hinged to the conveying plate 4 are fixedly mounted at both ends of the rotating rods 301; and a gear 303 is fixedly mounted on one end of one of the rotating rods 301; a transmission structure cooperating with the gear 303 is provided on the turntable 13.

[0052] In another embodiment of the present invention, the transmission structure includes an annular groove 1301 opened on the turntable 13, and multiple groups of first tooth blocks 1302 and second tooth blocks 1303 engaged with the gear 303 are fixedly installed on the groove walls on both sides of the annular groove 1301; and the first tooth blocks 1302 and the second tooth blocks 1303 are staggered.

[0053] Taking the embodiment combining all the features described in the present application as an example, when the first conveyor pulley 603 rotates, the second conveyor pulley 1201 is driven to rotate through the belt, thereby driving the conveyor shaft 12 to rotate, and driving the turntable 13 to rotate.

[0054] The rotating turntable 13 can drive the first tooth block 1302 and the second tooth block 1303 to rotate. When the first tooth block 1302 and the second tooth block 1303 rotate, they can engage with the gear 303; thereby driving the rotating rod 301 to rotate, thereby driving the connecting rod 302 to rotate, thereby driving the transmission plate 4 to move in an arc. During the movement, the transmission plate 4 and the connecting rod 302 rotate relative to each other.

[0055] When the protrusion 702 slides in the second inclined groove 903 , the gear 303 is not engaged with the first tooth block 1302 and the second tooth block 1303 , that is, when the clamping mechanism clamps the container 18 , the rotating rod 301 does not rotate.

[0056] When the protrusion 702 slides in the second flat groove 904 , the gear 303 meshes with the first tooth block 1302 , and the rotating rod 301 rotates, thereby driving the transmission plate 4 to move from the conveyor belt 2 to the pressure plate 14 .

[0057] When the protrusion 702 slides in the first inclined groove 901 , the gear 303 is not engaged with the first tooth block 1302 and the second tooth block 1303 , that is, when the clamping mechanism releases the container 18 , the rotating rod 301 does not rotate.

[0058] When the protrusion 702 slides in the first flat groove 902, the gear 303 engages with the second tooth block 1303, and the rotating rod 301 rotates in the opposite direction to the rotation direction of the rotating rod 301 when the protrusion 702 slides in the second flat groove 904, thereby driving the transmission plate 4 to move from the pressure plate 14 to the conveyor belt 2.

[0059] During the movement of the conveying plate 4, it will always remain parallel to the bracket 3, so that the container 18 can be conveyed smoothly and the possibility of collision and tilting during the conveying process is avoided.

[0060] By means of the alternating movements and cooperation between the clamping mechanism and the conveying mechanism, the container 18 can be conveyed more smoothly, and leakage of the product due to external reasons such as shaking and tilting during the conveying process can be avoided. The packaging efficiency of the quantitative packaging machine can be effectively improved, and frequent debugging of the quantitative packaging machine due to detection errors can be avoided, thereby indirectly increasing the service life of the quantitative packaging machine.

[0061] In another embodiment of the present invention, limit blocks 304 for support are symmetrically installed at both ends of the bracket 3.

[0062] Taking the embodiment combining all the features described in the present application as an example, when in use, when the transmission plate 4 is located on the conveyor belt 2 or at the pressure plate 14, the connecting rod 302 conflicts with the limit block 304; at this time, the gear 303 is not engaged with the first tooth block 1302 and the second tooth block 1303, so the limit block 304 can support the connecting rod 302 to prevent the connecting rod 302 from deflecting due to gravity and affecting the subsequent action execution.

[0063] In another embodiment of the present invention, the conveyor belt 2 and the pressure plate 14 are located at the same level.

[0064] Taking the embodiment combining all the features described in the present application as an example, when in use, the conveyor belt 2 and the pressure plate 14 are located at the same level, which can facilitate the alternating action and coordination between the clamping mechanism and the transmission mechanism, thereby reducing the failure rate of the device.
