Description

Technical Field

[0001] The invention relates to the technical field of piglet feed processing and packaging tools, in particular to a quantitative packaging device for piglet feed processing. Background Art

[0002] With the development of pig farming, the demand for piglet feed in the market is increasing. In order to meet the demand for piglet feed in the farming market, more and more feed companies will use a quantitative packaging equipment to quantitatively package the piglet feed. Through this quantitative packaging equipment, the piglet feed is bagged and sealed according to a certain quality, so that it is convenient to sell in the market.

[0003] However, the existing quantitative packaging equipment has great defects during use. The existing quantitative packaging equipment weighs when bagging, and the weighing process is slow, which will slow down the bagging speed, resulting in low efficiency of the equipment in quantitative packaging and processing of piglet feed. The existing quantitative packaging equipment only weighs when bagging, and there is no subsequent secondary weighing verification. Once an error occurs in the bagging weighing, the quality of the packaged piglet feed will not meet the standards. At the same time, if the bagging weighing components are not accurate enough, the quality of the piglet feed packaged by the equipment will deviate from the standard quality. The existing quantitative packaging equipment weighing, bagging and sealing processing links share a conveyor belt, so that the packaging bag of the packaged piglet feed can only be positioned at one place on the conveyor belt, and multiple packaging bags on the conveyor belt cannot be positioned at each processing link at the same time, and multiple processing links cannot be operated at the same time, resulting in low parallelism of the entire processing link of the equipment. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a quantitative packaging device for processing piglet feed.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a quantitative packaging device for piglet feed processing, including a supporting base plate, a conveying component, a packaging component, a feeding component and a sealing component, the conveying component includes a first supporting frame, a first conveyor belt, a second conveyor belt and a third conveyor belt, the first supporting frame is installed on the top of the supporting base plate by bolts, the first conveyor belt, the second conveyor belt and the third conveyor belt are fixed on the top of the first supporting frame in sequence, the second conveyor belt is located between the first conveyor belt and the third conveyor belt, the bottom of the second conveyor belt is provided with a floor scale, and by setting The floor scale weighs the quantitatively bagged piglet feed to determine whether the quality of the bagged components of the sub-packaging assembly meets the standard. On the one hand, it can prevent the quality of the piglet feed bagged by the sub-packaging assembly from being significantly different from the predetermined standard, thereby preventing the quantitatively packaged products that do not meet the quality standards from passing through the equipment production line. On the other hand, it can verify the weighing in the sub-packaging assembly to determine whether the weighing components in the sub-packaging assembly are defective, thereby preventing the equipment from causing greater production errors. At the same time, by verifying the weighing of the sub-packaging assembly, the error of the sub-packaging assembly can be reduced. The material assembly and the sealing assembly are both installed on the top of the supporting base plate, the subpackaging assembly is located on one side of the first conveyor belt, the feeding assembly is located on one side of the second conveyor belt, and the sealing assembly is located above the third conveyor belt. By using a floor scale to weigh the quantitatively bagged piglet feed, and cooperating with the feeding assembly to make up the missing mass of the feed in the packaging bag, on the one hand, the error between the quality of the quantitatively packaged feed of the equipment and the standard mass is made smaller, on the other hand, by setting the feeding assembly to make up the missing mass, the feed that has been filled in the packaging bag by the subpackaging assembly does not need to be poured out or returned to the subpackaging assembly for secondary filling, thereby avoiding the occurrence of rework, by using the subpackaging assembly for bagging, using the feeding assembly for feeding, using the sealing assembly for sealing, and cooperating with the conveying assembly for conveying, the entire quantitative packaging process of the equipment is more streamlined, by using the first conveyor belt, the second conveyor belt and the third conveyor belt for cooperation, each processing link is independent of each other, and each processing link does not affect each other, thereby enabling the equipment to locate the position of products in different states at different links, thereby making the parallel ability of each processing link of the equipment stronger;

When the packaging component pours piglet feed into the packaging bag, it will not delay time due to the weighing of the piglet feed, thereby enabling the packaging component to be filled into the packaging bag. The speed of bagging piglet feed is faster. At the same time, when one of the weighing boxes pours the piglet feed into the packaging bag through the lower hopper, the other weighing box has sufficient time to receive the piglet feed from the storage hopper, so that the quality of the feed finally loaded in the weighing box is closer to the predetermined packaging standard quality.

The position of the third support frame is moved by using the first motor to drive, and the position of the discharge pipe is adjusted by moving the position of the third support frame, so that the discharge pipe can be more accurately aligned with the bag opening of the packaging bag, thereby reducing leakage during feeding.

The cross-section of the roller is an "I"-shaped structure, and the rollers roll on the slide rails. The third support frame is moved and engaged on the top of the base plate through the rollers.

By rotating the two clamping plates, the sealing assembly can seal the packaging bag with an inclined bag mouth without adjusting the angle of the packaging bag, thereby eliminating the need to adjust the packaging bag when sealing the packaging bag.

[0015] Preferably, the processing method of the quantitative packaging equipment for piglet feed processing specifically comprises the following steps:

[0016] Step 1: Load the piglet feed into the storage hopper and the feeding hopper, place the packaging bag on a section of the conveyor belt, and convey the packaging bag to the bottom of the lower hopper of the sub-packaging component through a section of the conveyor belt. The first hydraulic cylinder drives the first hydraulic rod to move, and the first hydraulic rod drives the sealing plate to rotate. By rotating the sealing plate, the piglet feed in the storage hopper enters the weighing box through the distributing port, and the weighing sensor is used to monitor the quality of the piglet feed loaded in the weighing box.

[0018] Step 3: The packaging bag containing the piglet feed is conveyed to the third-section conveyor belt through the second-section conveyor belt, and the packaging bag containing the piglet feed is conveyed to the sealing assembly through the third-section conveyor belt, so that the bag opening of the packaging bag is between the two clamping plates, and the third hydraulic cylinder is driven to move the third hydraulic rod, and the two clamping plates are driven by the third hydraulic cylinder and the third hydraulic rod to approach each other, and the two heat sealing heads are pressed against the bag opening, and the bag opening of the packaging bag is heat-sealed by the two heat sealing heads. At this time, the quantitative packaging of the piglet feed is completed.

[0019] Beneficial effects of the present invention:

[0020] (1) In the present invention, a storage hopper is provided to store a large amount of piglet feed in advance, so that the equipment can continuously process and produce after loading once, thereby reducing the number of times the equipment is loaded, thereby improving the convenience of using the equipment. At the same time, the storage hopper is used to pre-store piglet feed, so that the packaging process of the equipment for piglet feed can be continuous, thereby making the equipment more capable of packaging and processing piglet feed. The equipment is provided with two weighing boxes. When one weighing box loads piglet feed into the packaging bag through the lower hopper, the other weighing box can weigh the amount of piglet feed to be loaded into the next packaging bag in advance. When the packaging component fills the packaging bag with piglet feed, there is no delay due to the weighing of the piglet feed, thereby making the speed of the packaging component filling the packaging bag with piglet feed faster, thereby improving the efficiency of the equipment in quantitatively packaging piglet feed. At the same time, one of the weighing boxes fills the packaging bag with piglet feed through the lower hopper. When feeding, the other weighing box has sufficient time to take the piglet feed from the storage hopper, so that the quality of the feed finally loaded in the weighing box is closer to the predetermined packaging standard quality, thereby improving the accuracy of the quantitative packaging of the equipment. By setting the lower hopper, the weighed piglet feed is loaded into the packaging bag. On the one hand, the lower hopper corresponds to two weighing boxes, and the bottom opening of the lower hopper is fixed. No matter which weighing box the piglet feed needs to be loaded into the packaging bag, the position of the packaging bag does not need to be changed, thereby making the control logic of the packaging bag of the equipment simpler, thereby making the operation process of the equipment less prone to errors. On the other hand, through the lower hopper, the piglet feed can be more easily poured into the packaging bag, thereby reducing the leakage of the piglet feed when bagging, thereby reducing the waste of feed when the equipment is bagging, and at the same time, it also reduces the burden of cleaning the leaked feed after the use of the equipment, thereby further improving the convenience of using the equipment.

[0021] (2) In the present invention, a floor scale is set to weigh the quantitatively bagged piglet feed to determine whether the quality of the bagged piglets in the packaging assembly meets the standard. On the one hand, it can prevent the quality of the piglet feed bagged by the packaging assembly from being significantly different from the predetermined standard, thereby preventing the quantitatively packaged products that do not meet the quality standards from passing through the equipment production line, thereby reducing the unqualified rate of the quantitatively packaged products of the equipment. On the other hand, the weighing in the packaging assembly can be verified to determine whether the weighing components in the packaging assembly are defective, thereby preventing the equipment from causing greater production errors, thereby making the use of the equipment more reliable. At the same time, by verifying the weighing of the packaging assembly, the error of the packaging assembly can be reduced, thereby further improving the accuracy of the quantitative packaging of the piglet feed by the equipment. By using a floor scale to weigh the quantitatively bagged piglet feed, the quantitatively bagged piglet feed can be accurately packaged. The feeding component is used to make up the missing mass of the feed in the packaging bag, and cooperates with the feeding component to make up for the missing mass of the feed in the packaging bag. On the one hand, the error between the mass of the feed quantitatively packaged by the equipment and the standard mass is made smaller, so that the quantitative measurement of the equipment is more accurate. On the other hand, by setting the feeding component to make up the missing mass, the feed that has been filled in the packaging bag by the dispensing component does not need to be poured out or returned to the dispensing component for secondary filling, thereby avoiding the occurrence of rework, thereby further improving the efficiency of the equipment in quantitatively packaging piglet feed. By using the first motor to drive the position of the third support frame to move the position of the third support frame, the position of the feed discharge pipe is adjusted by moving the position of the third support frame, so that the feed discharge pipe can be more accurately aligned with the bag mouth of the packaging bag, thereby reducing leakage during feeding, thereby further reducing the waste of piglet feed during quantitative packaging of the equipment.

[0022] (3) In the present invention, the fourth hydraulic cylinder drives the fourth hydraulic rod to move, and the fourth hydraulic rod drives the rotating boom to rotate through the turntable, thereby driving the two clamping plates to rotate. By rotating the two clamping plates, the sealing component can seal the packaging bag with an inclined bag mouth without adjusting the angle of the packaging bag, thereby making the device do not need to adjust the packaging bag when sealing the packaging bag, thereby making the use of the device more convenient. By using the sub-packaging component to pack the bags, using the feeding component to feed the materials, and sealing the bags through the sealing component, and cooperating with the conveying component for conveying, the entire quantitative packaging process of the device is more streamlined, thereby making the automation degree of the device higher. By using one-stage conveyor belt, two-stage conveyor belt and three-stage conveyor belt for cooperation, each processing link is independent of each other, and each processing link does not affect each other, thereby making the device able to locate the position of products in different states at different links, thereby making the parallel capability of each processing link of the device stronger, thereby making the processing efficiency of the device higher.

On the one hand, it can prevent the quality of the piglet feed packed by the subpackaging component 3 from being significantly different from the predetermined standard, thereby preventing the quantitatively packaged products that do not meet the quality standards from passing through the equipment production line, thereby reducing the unqualified rate of the quantitatively packaged products of the equipment. On the other hand, the weighing in the subpackaging component 3 can be verified to determine whether the weighing components in the subpackaging component 3 are defective, thereby preventing the equipment from causing greater production errors, thereby making the use of the equipment more reliable. At the same time, by verifying the weighing of the subpackaging component 3, the error of the subpackaging component 3 can be reduced, thereby further improving the accuracy of the equipment in quantitatively packaging piglet feed. The subpackaging component 3 and the supplementary material The component 4 and the sealing component 5 are both installed on the top of the supporting base plate 1, the packaging component 3 is located on one side of the first conveyor belt 202, the feeding component 4 is located on one side of the second conveyor belt 203, and the sealing component 5 is located above the third conveyor belt 205. The quantitatively bagged piglet feed is weighed by using the floor scale 204, and the missing mass of the feed in the packaging bag is supplemented with the feeding component 4. On the one hand, the error between the mass of the feed quantitatively packaged by the equipment and the standard mass is made smaller, so that the quantitative measurement of the equipment is more accurate. On the other hand, by setting the feeding component 4 to supplement the missing mass, the feed that has been filled in the packaging bag by the packaging component 3 does not need to be poured out or returned to the packaging component 3 for secondary filling, thereby The occurrence of rework is avoided, thereby further improving the efficiency of the device in quantitative packaging of piglet feed. By using the packaging component 3 for bagging, using the feeding component 4 for feeding, and using the sealing component 5 for sealing, and cooperating with the conveying component 2 for conveying, the entire quantitative packaging process of the device is more streamlined, thereby making the automation of the device higher. By using a conveyor belt 202, a conveyor belt 203 and a conveyor belt 205 for cooperation, each processing link is independent of each other, and each processing link does not affect each other, so that the device can locate the position of products in different states at different links, thereby making the parallel ability of each processing link of the device stronger, so that the processing efficiency of the device is higher;

[0035] The packaging component 3 includes a second support frame 301, a storage hopper 303 and a weighing sensor 309 (model: CYT202). The second support frame 301 is fixed to the support base plate 1 by bolts, the mounting frame 302 is fixed on the top of the second support frame 301, and the storage hopper 303 is fixed on the top of the mounting frame 302. By setting the storage hopper 303 to store a large amount of piglet feed in advance, the equipment can be continuously processed and produced after one loading, thereby reducing the number of loading times of the equipment, thereby improving the convenience of using the equipment. At the same time, by pre-loading the piglet feed in the storage hopper 303, the packaging process of the piglet feed by the equipment can be continuous, thereby making the equipment more capable of packaging and processing piglet feed. The bottom of the packaging bag 300 is provided with two dispensing ports 304 for controlling the discharging of materials. Two weighing boxes 308 corresponding to the two dispensing ports 304 are installed on the mounting frame 302 through weighing sensors 309 below the two dispensing ports 304. The equipment is provided with two weighing boxes 308. When one weighing box 308 is used to load piglet feed into the packaging bag through the lower hopper 313, the other weighing box 308 can weigh in advance the amount of piglet feed to be loaded into the next packaging bag. When the dispensing component 3 is pouring the piglet feed into the packaging bag, there will be no delay due to the weighing of the piglet feed, thereby making the dispensing component 3 load the piglet feed into the packaging bag faster, thereby improving the efficiency of the equipment in quantitatively packaging the piglet feed. At the same time, when one of the weighing boxes 308 is passed through the lower hopper 313, the other weighing box 308 can weigh in advance the amount of piglet feed to be loaded into the next packaging bag. When the piglet feed is poured into the packaging bag through the lower hopper 313, the other weighing box 308 has sufficient time to receive the piglet feed from the storage hopper 303, so that the quality of the feed finally loaded into the weighing box 308 is closer to the predetermined packaging standard quality, thereby improving the accuracy of the quantitative packaging of the equipment. The bottoms of the two weighing boxes 308 are provided with controllable discharge ports, and a funnel-shaped lower hopper 313 is installed on the mounting frame 302 below the two weighing boxes 308.

The piglet feed in a weighing box 308 needs to be put into a packaging bag, and the parking position of the packaging bag does not need to be changed, which makes the control logic of the device for the packaging bag simpler, making the operation process of the device less prone to errors. On the other hand, through the lower hopper 313, the piglet feed can be more easily poured into the packaging bag, which can reduce the leakage of the piglet feed during bagging, thereby reducing the waste of feed during bagging by the device, and at the same time, it also reduces the burden of cleaning the spilled feed after the use of the device, thereby further improving the convenience of using the device. A PLC controller (model: s7-300) is installed on the back of the first support frame 201 of the device, and the PLC controller controls the operation of each motor and each hydraulic cylinder on the device. At the same time,Photoelectric sensors (model: ESH-CX441ND) are installed on the first conveyor belt 202, the second conveyor belt 203 and the third conveyor belt 205 of the conveyor assembly 2 of the equipment.

A connecting plate 503 is fixed to the bottom of the rotating hanger 502. The two clamps 504 are respectively hinged at both ends of the connecting plate 503. The two clamps 504 and the connecting plate 503 form an "H"-shaped structure as a whole. A third hydraulic cylinder 506 is hinged on the top of one of the clamps 504. A third hydraulic cylinder 506 is provided at one end of the third hydraulic cylinder 506. The end of the third hydraulic rod 507 away from the third hydraulic cylinder 506 is hinged to the top of the other clamp 504. A heat sealing head 505 is installed on one side of the bottom of the two clamps 504. The heat sealing head 505 is a rod-shaped mold that can be heated internally.

The fourth hydraulic rod 510 is moved by the fourth hydraulic cylinder 509, and the fourth hydraulic rod 510 drives the rotating boom 502 to rotate through the turntable 508, thereby driving the two clamping plates 504 to rotate. By rotating the two clamping plates 504, the sealing assembly 5 can seal the packaging bag with an inclined bag mouth without adjusting the angle of the packaging bag, so that the device does not need to adjust the packaging bag when sealing the packaging bag, thereby making the use of the device more convenient.

[0044] In an optional implementation manner of this embodiment, the processing method of the quantitative packaging equipment for piglet feed processing specifically includes the following steps:

[0045] Step 1: put the piglet feed into the storage hopper 303 and the replenishing hopper 408, place the packaging bag on a section of the conveyor belt 202, and convey the packaging bag to the bottom of the lower hopper 313 of the sub-packaging component 3 through a section of the conveyor belt 202. The first hydraulic cylinder 306 drives the first hydraulic rod 307 to move, and the first hydraulic rod 307 drives the sealing plate 305 to rotate. By rotating the sealing plate 305, the piglet feed in the storage hopper 303 enters the weighing box 308 through the distributing port 304, and is weighed. The weight sensor 309 monitors the quality of the piglet feed in the weighing box 308. When the piglet feed in the weighing box 308 reaches the bagging standard, the sealing plate 305 is driven to rotate by the first hydraulic cylinder 306 to block the feed outlet 304. The second hydraulic cylinder 311 drives the second hydraulic rod 312 to move, and the second hydraulic rod 312 drives the baffle plate 310 to rotate. By rotating the baffle plate 310, all the piglet feed in the weighing box 308 is loaded into the packaging bag through the lower hopper 313.

[0046] Step 2: The packaging bag containing the piglet feed is conveyed to the second conveyor belt 203 through the first conveyor belt 202, and the feed in the packaging bag is weighed by the floor scale 204. When the quality of the feed in the packaging bag is much lower than the standard quality of the packaging bag, the first motor 404 drives the screw rod 403 to rotate, and the nut 407 is moved by rotating the screw rod 403, and the nut 407 drives the third support frame 405 to move, and the third support frame 405 is moved to make the discharge pipe 410 face the bag opening of the packaging bag, and the second motor 411 drives the auger 412 to rotate, and the piglet feed in the feeding hopper 408 is conveyed to the discharge pipe 410 through the conveying cylinder 409, and falls into the packaging bag through the discharge pipe 410, until the weighing result of the feed in the packaging bag by the floor scale 204 reaches the standard quality of the packaging bag, and the feeding component 4 stops replenishing the piglet feed into the packaging bag;

[0047] Step 3: The packaging bag containing the piglet feed is conveyed to the three-section conveyor belt 205 through the two-section conveyor belt 203, and the packaging bag containing the piglet feed is conveyed to the sealing component 5 through the three-section conveyor belt 205, so that the bag opening of the packaging bag is between the two clamping plates 504, and the third hydraulic cylinder 506 is driven to move the third hydraulic rod 507, and the two clamping plates 504 are driven by the third hydraulic cylinder 506 and the third hydraulic rod 507 to approach each other, and the two heat sealing heads 505 are pressed against the bag opening, and the bag opening of the packaging bag is heat-sealed by the two heat sealing heads 505. At this time, the quantitative packaging of the piglet feed is completed.

[0048] When in use, first, the piglet feed is loaded into the storage hopper 303 and the replenishing hopper 408, and the packaging bag is placed on a section of the conveyor belt 202, and the packaging bag is conveyed to the bottom of the lower hopper 313 of the sub-packaging component 3 by a section of the conveyor belt 202, and the first hydraulic rod 307 is driven by the first hydraulic cylinder 306 to move, and the first hydraulic rod 307 drives the sealing plate 305 to rotate, and by rotating the sealing plate 305, the piglet feed in the storage hopper 303 enters the weighing box 308 through the distributing port 304, and the quality of the piglet feed loaded in the weighing box 308 is monitored by the weighing sensor 309. When the piglet feed in the weighing box 308 reaches the bagging standard, the sealing plate 305 is driven by the first hydraulic cylinder 306 to rotate, and the distributing port 304 is blocked, and the sealing plate 305 is opened. The second hydraulic rod 312 is driven by the second hydraulic cylinder 311 to move, and the second hydraulic rod 312 drives the baffle plate 310 to rotate. By rotating the baffle plate 310, all the piglet feed in the weighing box 308 is loaded into the packaging bag through the lower hopper 313. By setting the storage hopper 303 to pre-store a large amount of piglet feed, the equipment can continuously process and produce after one loading, thereby reducing the number of loading times of the equipment, thereby improving the convenience of using the equipment. At the same time, the storage hopper 303 is pre-loaded with piglet feed, so that the packaging process of the piglet feed of the equipment can be continuous, thereby making the equipment more capable of packaging and processing piglet feed. The equipment is provided with two weighing boxes 308, one weighing box 308 is passed through the lower hopper When 313 is filling the packaging bag with piglet feed, the other weighing box 308 can weigh in advance the amount of piglet feed that needs to be put into the next packaging bag. When the dispensing component 3 is filling the packaging bag with piglet feed, there is no delay due to the weighing of the piglet feed, so that the speed of the dispensing component 3 filling the packaging bag with piglet feed is faster, thereby improving the efficiency of the equipment in quantitative packaging of piglet feed. At the same time, when one of the weighing boxes 308 is filling the packaging bag with piglet feed through the lower hopper 313, the other weighing box 308 has sufficient time to receive the piglet feed from the storage hopper 303, so that the quality of the feed finally filled in the weighing box 308 is closer to the predetermined packaging standard quality, thereby improving the accuracy of the quantitative packaging of the equipment. The hopper 313 puts the weighed piglet feed into the packaging bag. On the one hand, the lower hopper 313 corresponds to the two weighing boxes 308, and the bottom opening of the lower hopper 313 is fixed. No matter which weighing box 308 the piglet feed needs to be put into the packaging bag, the parking position of the packaging bag does not need to be changed, thereby making the control logic of the packaging bag of the device simpler, thereby making the operation process of the device less prone to errors. On the other hand, through the lower hopper 313, the piglet feed can be poured into the packaging bag more easily, thereby reducing the leakage of the piglet feed when bagging, thereby reducing the waste of feed when the device is bagging, and at the same time, it also reduces the burden of cleaning the leaked feed after the use of the device, thereby further improving the convenience of using the device, and then,The packaging bag containing piglet feed is conveyed to the second conveyor belt 203 through the first conveyor belt 202, and the feed in the packaging bag is weighed by the floor scale 204. When the quality of the feed in the packaging bag is much lower than the standard quality of the packaging bag, the first motor 404 drives the screw rod 403 to rotate, and the nut 407 is moved by rotating the screw rod 403, and the nut 407 drives the third support frame 405 to move. By moving the third support frame 405, the discharge pipe 410 is directly opposite to the bag opening of the packaging bag, and the auger 412 is driven to rotate by the second motor 411, and the piglet feed in the feeding hopper 408 is conveyed to the discharge pipe 410 through the conveying cylinder 409, and falls into the packaging bag through the discharge pipe 410 until the weighing result of the feed in the packaging bag by the floor scale 204 is obtained. If the standard quality of the sealed bag is reached, the feeding component 4 stops adding piglet feed to the sealed bag, and the quantitatively bagged piglet feed is weighed by setting a floor scale 204 to determine whether the quality of the bags packed by the packaging component 3 meets the standard. On the one hand, it can avoid a large gap between the quality of the piglet feed packed by the packaging component 3 and the predetermined standard, thereby preventing quantitatively packaged products that do not meet the quality standards from passing through the equipment production line, thereby reducing the unqualified rate of the quantitatively packaged products of the equipment. On the other hand, it can verify the weighing in the packaging component 3 to determine whether the weighing components in the packaging component 3 are defective, thereby preventing the equipment from causing greater production errors, thereby making the use of the equipment more reliable. At the same time, by verifying the weighing of the packaging component 3, The error of the packaging component 3 can be reduced, thereby further improving the accuracy of the device in quantitative packaging of piglet feed. By using the floor scale 204 to weigh the quantitatively bagged piglet feed, and cooperating with the feeding component 4 to make up the missing mass of the feed in the packaging bag, on the one hand, the error between the mass of the feed quantitatively packaged by the device and the standard mass is made smaller, thereby making the quantitative quantity of the device more accurate. On the other hand, by setting the feeding component 4 to make up the missing mass, the feed that has been filled in the packaging bag by the packaging component 3 does not need to be poured out or returned to the packaging component 3 for secondary filling, thereby avoiding the occurrence of rework, thereby further improving the efficiency of the device in quantitative packaging of piglet feed. By using the first motor 404 to drive, the mobile The position of the third support frame 405 is adjusted by moving the position of the third support frame 405, so that the feed tube 410 can be more accurately aligned with the bag mouth of the packaging bag, thereby reducing leakage during feeding, thereby further reducing the waste of piglet feed during quantitative packaging of the equipment. Finally, the packaging bag containing piglet feed is conveyed to the third-section conveyor belt 205 through the second-section conveyor belt 203, and the packaging bag containing piglet feed is conveyed to the sealing component 5 through the three-section conveyor belt 205, so that the bag mouth of the packaging bag is between the two clamping plates 504, and the third hydraulic cylinder 506 is driven to move the third hydraulic rod 507, and the two clamping plates 504 are moved closer to each other by the third hydraulic cylinder 506 and the third hydraulic rod 507.The two heat sealing heads 505 are used to press the bag opening tightly, and the bag opening of the packaging bag is heat-sealed by the two heat sealing heads 505. At this time, the quantitative packaging of the piglet feed is completed. The fourth hydraulic cylinder 509 drives the fourth hydraulic rod 510 to move. The fourth hydraulic rod 510 drives the rotating suspension rod 502 to rotate through the turntable 508, and then drives the two clamping plates 504 to rotate. By rotating the two clamping plates 504, the sealing component 5 can seal the packaging bag with an inclined bag opening without adjusting the angle of the packaging bag, so that the device does not need to adjust the packaging bag when sealing the packaging bag, so that the use of the device is more convenient. By using the packing component 3 for bagging, the feeding component 4 for feeding, the sealing component 5 for sealing, and the conveying component 2 for conveying, the entire quantitative packaging process of the equipment is more streamlined, thereby making the equipment more automated. By using a first-stage conveyor belt 202, a second-stage conveyor belt 203, and a third-stage conveyor belt 205 for cooperation, each processing link is independent of each other, and each processing link does not affect each other, so that the equipment can locate the position of products in different states at different links, thereby making the parallel ability of each processing link of the equipment stronger, so that the processing efficiency of the equipment is higher.
