Description

Technical Field

[0001] The present invention relates to the field of material feeding, and particularly to a deoxidizer feeding system. Background Art

[0002] A deoxidizer is an additive that can absorb oxygen and slow down the oxidation of food. It is widely used in food preservation. It is packed in a sealed paper bag with a certain air permeability and strength. Just like a desiccant bag, the deoxidizer is wrapped in the food bag and sealed together with the food, which can remove the oxygen remaining in the air in the bag, prevent the food from discoloring, deteriorating and rancidity due to oxidation, and also inhibit the growth of molds, aerobic bacteria and grain pests.

[0003] Currently, common automatic deoxidizer feeding devices all adopt the form of slicing deoxidizer in a reel. It is easy to cut the deoxidizer packet, causing pollution to the food. Moreover, it is relatively troublesome to replace the material, with high requirements for the operation of workers, and there is a potential hazard that the cutting knife may cause harm to the workers; the number of deoxidizers in each reel is large, and the deoxidizer needs to be fed within a certain time, otherwise it will become ineffective due to excessive absorption of oxygen in the air. If abnormal conditions occur during the production process and cause downtime, it will result in the invalidation of the deoxidizer and waste. Summary of the Invention

[0004] In order to solve the existing technical problems, an embodiment of the present invention provides a deoxidizer feeding system that can accurately and efficiently feed bulk deoxidizer packets smoothly.

[0005] To achieve the above object, the technical solution of the embodiment of the present invention is realized as follows:

[0006] A deoxidizer feeding system includes a frame, a deoxidizer extraction device and a deoxidizer separation device installed on the frame.

[0007] The deoxidizer extraction device includes a drum installed on the frame, a drum motor for driving the drum to rotate, and a magnetic attraction mechanism provided on the drum. A receiving cavity is provided inside the drum, and the receiving cavity is used for storing deoxidizer packets to be fed.

[0008] The deoxidizer separation device includes a plurality of receiving grooves extending into the receiving cavity and facing the inner surface above the drum.

[0009] The magnetic attraction mechanism includes a magnetic attraction member provided on the roller. The magnetic attraction member switches between an adsorption state in which it is attached to the outer surface of the roller and a release state in which it is spaced apart from the outer surface of the roller as the roller rotates. When the magnetic attraction member is in the adsorption state, the target deoxidizer packet is adsorbed to the inner surface of the roller by magnetic attraction. When the magnetic attraction member is in the release state, the magnetic attraction force acting on the adsorbed target deoxidizer packet is eliminated, and the target deoxidizer packet falls from the inner surface of the roller into the material receiving groove.

[0010] The magnetic attraction mechanism further includes a magnetic attraction shaft connected to opposite ends of the roller and a magnetic attraction mounting block mounted on the magnetic attraction shaft. The first end of the magnetic attraction mounting block is connected to the magnetic attraction shaft, and the magnetic attraction member is provided at the second end of the magnetic attraction mounting block relatively far from the magnetic attraction shaft.

[0011] Optionally, the magnetic attraction mechanism further includes a trigger arm connected to the magnetic attraction shaft and a dial provided at one end of the roller. When the roller rotates to a trigger position where a certain magnetic attraction shaft is located above the roller, the trigger arm corresponding to the magnetic attraction shaft contacts the dial to drive the magnetic attraction shaft to rotate. The magnetic attraction shaft drives the magnetic attraction mounting block to rotate, thereby switching the magnetic attraction member to the release state.

[0012] Optionally, the side surface of the roller includes a plurality of planes connected to each other in the circumferential direction. A plurality of the magnetic attraction shafts are provided on each plane. The magnetic attraction shafts on each plane and the magnetic attraction mounting blocks and magnetic attraction members connected thereto form a magnetic attraction assembly. The magnetic attraction mechanism further includes a swing arm connected to the magnetic attraction shafts in each group of the magnetic attraction assemblies and a connecting rod connecting the swing arms. One end of the swing arm is fixedly connected to the corresponding magnetic attraction shaft, and the other end is rotatably connected to the connecting rod.

[0013] Optionally, the number of the material receiving grooves corresponds to the number of the magnetic attraction shafts included in a group of the magnetic attraction assemblies, and the material receiving grooves respectively correspond to a plurality of the magnetic attraction shafts in the magnetic attraction assemblies located above the roller one by one.

[0014] Optionally, the magnetic attraction mechanism further includes a return spring connected to one end of the connecting rod. When a magnetic attraction assembly follows the roller and rotates through the trigger position above the roller, the connecting rod and the swing arm drive the magnetic attraction shafts in the magnetic attraction assembly to rotate simultaneously to switch to the release state, and the return spring is in a stretched deformation state. After the magnetic attraction assembly follows the roller and rotates through the trigger position, the return spring restores its deformation to drive the connecting rod and the swing arm to drive the magnetic attraction assembly to return to the initial position.

[0015] Optionally, the deoxidizer separation device further includes a separation assembly, which includes a conveyor belt correspondingly connected to the material receiving tank, separation pressing plates straddling opposite sides of the conveyor belt, and a separation wheel located above the conveyor belt. Along the conveying direction of the conveyor belt, the separation wheel is arranged in front of the separation pressing plates.

[0016] Optionally, the separation assembly further includes a torsion spring, a pressing plate adjusting member, and a mounting shaft that cooperate with the separation pressing plates. The mounting shaft is connected to the side plates on opposite sides of the material receiving tank. The separation pressing plates are rotatably connected to the mounting shaft. The pressing plate adjusting member is adjustably locked on the mounting shaft. The first end of the torsion spring abuts against the separation pressing plates, and the second end abuts against the pressing plate adjusting member; and / or,

[0017] The separation assembly further includes a separation wheel adjusting member and an adjusting bolt assembly. The first end of the separation wheel adjusting member is connected to the mounting shaft of the separation pressing plates, and the second end is connected to the driving shaft of the separation wheel. The adjusting bolt assembly abuts against the second end of the separation wheel adjusting member to adjust the separation wheel adjusting member to rotate around the mounting shaft and change the distance between the separation wheel and the conveyor belt.

[0018] Optionally, the separation assembly further includes a driving shaft connected to the conveyor belt, a separation motor, a transmission structure connected between the separation motor and the driving shaft, and an elastic conveyor belt connected between the driving shaft and the driving shaft of the separation wheel.

[0019] Optionally, the deoxidizer feeding system further includes a feeding device, which includes a temporary storage tank correspondingly connected to the material receiving tank, a baffle door arranged in the temporary storage tank, and a driving member for driving the baffle door to open or close. When the baffle door is opened, the deoxidizer packages located in the temporary storage tank slide out under the action of gravity and fall to the target position.

[0020] The deoxidizer feeding system provided in the above embodiment uses a drum and a magnetic attraction mechanism arranged on the drum to extract the deoxidizer packages to be fed and put them into the corresponding material receiving tank. When the magnetic attraction member is in the adsorption state, it can adsorb the deoxidizer packages on the inner surface of the drum. When in the release state, it cancels the adsorption force on the adsorbed deoxidizer packages, causing them to fall into the material receiving tank. The magnetic attraction mechanism uses the continuous rotation of the drum to complete the switching of the magnetic attraction member between the adsorption state and the release state, so as to ensure the continuous extraction of bulk deoxidizer packages and achieve the purpose of accurately and efficiently putting the bulk deoxidizer packages smoothly.

The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. In the following description, the expression "some embodiments" describes a subset of all possible embodiments, but it should be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0028] Please refer to Figure 1 and Figure 2, which is a schematic diagram of the deoxidizer feeding system provided by the embodiment of the present invention, includes a frame 10, a deoxidizer extraction device 20 and a deoxidizer separation device 30 installed on the frame 10; the deoxidizer extraction device 20 includes a drum 22 installed on the frame 10, a drum motor for driving the rotation of the drum 22 and a magnetic attraction mechanism provided on the drum 22. A receiving cavity is provided inside the drum 22, and the receiving cavity is used for storing deoxidizer packets to be fed; the deoxidizer separation device 30 includes a plurality of material receiving grooves 31 extending into the receiving cavity and facing the inner surface above the drum 22; the magnetic attraction mechanism includes a magnetic attraction member 231 provided on the drum 22, and the magnetic attraction member 231 follows the rotation of the drum 22 and switches between an adsorption state in which it is in contact with the outer surface of the drum 22 and a release state in which it is spaced from the outer surface of the drum 22. When the magnetic attraction member 231 is in the adsorption state, the target deoxidizer packet is adsorbed on the inner surface of the drum 22 by magnetic attraction. When the magnetic attraction member 231 is in the release state, the magnetic attraction force acting on the adsorbed target deoxidizer packet is eliminated, and the target deoxidizer packet falls from the inner surface of the drum 22 into the material receiving groove 31.

[0029] For the deoxidizer feeding system provided in the above embodiment, the drum 22 and the magnetic attraction mechanism provided on the drum 22 are used to extract the deoxidizer packets to be fed and put them into the corresponding material receiving grooves 31. When the magnetic attraction member 231 is in the adsorption state, the deoxidizer packet can be adsorbed on the inner surface of the drum 22. When in the release state, the adsorption force on the adsorbed deoxidizer packet is withdrawn, causing it to fall into the material receiving groove 31. The magnetic attraction mechanism uses the continuous rotation of the drum 22 to complete the switching of the magnetic attraction member 231 between the adsorption state and the release state, so as to ensure the continuous extraction of bulk deoxidizer packets and achieve the purpose of accurately and efficiently feeding the bulk deoxidizer packets smoothly.

[0030] The frame 10 is in the shape of a rectangular frame. The drum 22 is generally a multi-faceted cylinder, including a cylinder body 220 and a first bottom plate 221 and a second bottom plate 221 respectively located at both ends of the main body 220. The centers of the first bottom plate 221 and the second bottom plate 221 are both open. A plurality of supporting rollers 11 for supporting the drum 22 are provided on the frame 10. The supporting rollers 11 are installed on the frame 10. The sizes of the first bottom plate 221 and the second bottom plate 221 of the drum 22 are larger than the diameter of the cylinder body 220. The supporting rollers 11 respectively support the edges of the first bottom plate 221 and the second bottom plate 221 of the drum 22. The deoxidizer feeding system further includes a deoxidizer adding device 50. The deoxidizer adding device 50 is installed at one end of the frame 10 close to the first bottom plate, and deoxidizer is added into the drum 22 through the opening of the first bottom plate. The receiving trough of the deoxidizer separating device 30 extends into the drum 22 from the opening of the second bottom plate. The receiving trough 31 faces the inner surface above the drum 22 to receive the deoxidizer packets extracted by the magnetic attraction mechanism and convey them out of the drum 22. The deoxidizer adding device 50 includes a feeding hopper. The upper end of the feeding hopper is in an outward-expanding shape, and the lower end is in a reducing shape. The reduced opening at the lower end extends into the drum 22 through the central opening of the first bottom plate. The deoxidizer packets are poured into the feeding hopper from the upper expanded opening and slide into the drum 22 through the lower reduced opening. Installation columns for hanging the feeding hopper can be provided on the frame 10. The feeding hopper is installed on the frame 10 by hanging on the installation columns, which can be quickly disassembled and assembled, facilitating the cleaning and maintenance of the interior of the drum 22.

[0031] In some embodiments, the magnetic attraction mechanism further includes a magnetic attraction shaft 232 connected to opposite ends of the drum 22 and a magnetic attraction mounting block 233 installed on the magnetic attraction shaft 232. The first end of the magnetic attraction mounting block 233 is connected to the magnetic attraction shaft 232, and the magnetic attraction member 231 is provided at the second end of the magnetic attraction mounting block 233 relatively far from the magnetic attraction shaft 232. Both ends of the magnetic attraction shaft 232 are respectively connected to the first bottom plate and the second bottom plate of the drum 22. The magnetic attraction mounting block 233 can rotate along with the magnetic attraction shaft 232, thereby driving the magnetic attraction member 231 installed on the magnetic attraction mounting block 233 to rotate together. A plurality of magnetic attraction shafts 232 are arranged at equal intervals along the circumferential direction of the drum 22. One magnetic attraction mounting block 233 is connected to each magnetic attraction shaft 232, and one magnetic attraction member 231 is provided on each magnetic attraction mounting block 233.

[0032] Among them, the magnetic attraction mechanism further includes a trigger arm 234 connected to the magnetic attraction shaft 232 and a dial block 235 provided at one end of the drum 22. When the drum 22 rotates to a trigger position where a certain magnetic attraction shaft 232 is located above the drum 22, the trigger arm 234 corresponding to the magnetic attraction shaft 232 contacts the dial block 235 to drive the magnetic attraction shaft 232 to rotate. The magnetic attraction shaft 232 drives the magnetic attraction mounting block 233 to rotate, thereby switching the magnetic attraction member 231 to the release state. The dial block 235 is provided above the first bottom plate of the drum 22. When the drum 22 rotates, when the magnetic attraction shaft 232 rotates to a certain preset position above the drum 22, the trigger arm 234 of the magnetic attraction shaft 232 contacts the dial block 235. This preset position is the trigger position. The trigger arm 234 is blocked by the dial block 235 to drive the magnetic attraction shaft 232 to rotate, forcing the magnetic attraction member 231 to switch to the release state.

[0033] Optionally, the side surface of the drum 22 includes a plurality of planes connected to each other in the circumferential direction. A plurality of the magnetic attraction shafts 232 are provided on each plane. The magnetic attraction shafts 232 on each plane and the magnetic attraction mounting blocks 233 and magnetic attraction members 231 connected thereto form a magnetic attraction assembly. The magnetic attraction mechanism further includes a swing arm 236 connected to the magnetic attraction shafts 232 in each group of the magnetic attraction assemblies and a connecting rod 237 connecting the swing arm 236. One end of the swing arm 236 is fixedly connected to the corresponding magnetic attraction shaft 232, and the other end is rotatably connected to the connecting rod 237. A plurality of magnetic attraction shafts 232, magnetic attraction mounting blocks 233 and magnetic attraction members 231 are provided in the same group of magnetic attraction assemblies. And through the arrangement of the connecting rod 237 and the swing arm 236 among the plurality of magnetic attraction shafts 232 in the same group of magnetic attraction assemblies, when the trigger arm 234 drives one of the magnetic attraction shafts 232 to rotate, the swing arm 236 and the connecting rod 237 can drive the other magnetic attraction shafts 232 in the same group of magnetic attraction assemblies to rotate at the same angle and in the same direction.

[0034] Among them, the number of the material receiving grooves 31 corresponds to the number of the magnetic attraction shafts 232 included in one group of the magnetic attraction assemblies. The material receiving grooves 31 respectively correspond to a plurality of the magnetic attraction shafts 232 in the magnetic attraction assemblies located above the drum 22. The material receiving grooves 31 respectively correspond to the magnetic attraction shafts 232 in the same group of magnetic attraction assemblies. When the drum 22 rotates and a group of magnetic attraction assemblies pass through the trigger position, the plurality of magnetic attraction shafts 232 in the same group of magnetic attraction assemblies rotate together following the rotation of the drum 22, so that the magnetic attraction members 231 are away from the outer surface of the drum 22, and the deoxidizer packets originally adsorbed on the inner surface of the drum 22 fall into the corresponding material receiving grooves 31 due to the cancellation of the magnetic attraction force. In this way, the feeding efficiency of the deoxidizer packets can be improved.

[0035] In some embodiments, the magnetic attraction mechanism further includes a return spring 238 connected to one end of the connecting rod 237. When a magnetic attraction component rotates past the trigger position above the roller 22 following the rotation of the roller 22, the connecting rod 237 and the swing arm 236 drive the magnetic attraction shaft 232 within the magnetic attraction component to rotate simultaneously and switch to the release state. The return spring 238 is in a stretched deformation state. After the magnetic attraction component rotates past the trigger position following the rotation of the roller 22, the return spring 238 restores its deformation and drives the connecting rod 237 and the swing arm 236 to drive the magnetic attraction component back to the initial position. One end of the return spring 238 is connected to the connecting rod 237, and the other end is fixedly connected to the roller 22. Through the design of the return spring 238, it can be ensured that the magnetic attraction shaft 232 can be accurately reset following the continued rotation of the roller 22 after passing through the trigger position, ensuring the next delivery of the deoxidizer package.

[0036] In this embodiment, the drum 22 is an octagonal cylinder, and there are eight groups of magnetic attraction components, which are respectively arranged on the eight side surfaces of the cylinder 220. The same group of magnetic attraction components includes three magnetic attraction shafts 232 installed on the bottom plates 221 at both ends of the cylinder 220. A magnetic attraction mounting block 233 is fixedly installed on each magnetic attraction shaft 232. The magnetic attraction mounting blocks 233 on the three magnetic attraction shafts 232 are staggeredly distributed along the axial direction of the drum 22. The magnetic attraction mounting block 233 is attached to the outer surface of the side surface of the cylinder 220. The first end of the magnetic attraction mounting block 233 is fixedly penetrated through the magnetic attraction shaft 232 and can swing following the rotation of the magnetic attraction shaft 232. The magnetic attraction member 231 is arranged at the second end of the magnetic attraction mounting block 233. As the magnetic attraction mounting block 233 swings, the magnetic attraction member 231 switches between approaching the outer surface of the cylinder and moving away from the outer surface of the cylinder. When the magnetic attraction member 231 approaches the outer surface of the cylinder, the deoxidizer is adsorbed on the inner surface of the cylinder through magnetic attraction. When the magnetic attraction member 231 rotates to the uppermost position following the rotation of the drum 22 and the magnetic attraction member 231 moves away from the outer surface of the cylinder, the magnetic attraction force acting on the deoxidizer is eliminated, and the deoxidizer drops from the inner surface of the cylinder 220. The material receiving groove 31 includes three corresponding to the magnetic attraction shafts 232 within the same group of magnetic attraction components respectively. Each group of magnetic attraction components includes three swing arms 236 fixedly connected to the three magnetic attraction shafts 232 respectively and a connecting rod 237 connecting the three swing arms 236 together. When one of the magnetic attraction components passes through the trigger position and the dial block 235 drives one of the magnetic attraction shafts 232 to rotate through the trigger arm 234, the other two magnetic attraction shafts 232 within the same group are driven to rotate by the same angle and in the same direction through the swing arms 236 and the connecting rod 237. The dial block 235 is installed on the frame 10 and is arranged at the trigger position of the magnetic attraction component at the uppermost part of the cylinder. The drum 22 rotates under the drive of the drum motor. The magnetic attraction member 231 close to the outer surface of the cylinder of the drum 22 adsorbs the deoxidizer on the inner surface of the cylinder. As the drum 22 rotates, the unadsorbed deoxidizer drops to the lower part of the cylinder 220 under the action of gravity. Only the deoxidizer adsorbed by the magnetic attraction member 231 clings to the inner surface of the cylinder and continues to rotate upward. When the magnetic attraction component adsorbing the deoxidizer reaches the uppermost position, the dial block 235 forms an obstruction to the trigger arm 234, as Figure 3 shown by the moving arrow, causing the trigger arm 234 to swing around the magnetic attraction shaft 232 and drive the magnetic attraction shaft 232 to rotate. The magnetic attraction mounting block 233 swings following the magnetic attraction shaft 232, causing the magnetic attraction member 231 to move away from the outer surface of the cylinder. At the same time, the adsorption force direction of the magnetic attraction member 231 no longer faces the cylinder 220, and the deoxidizer loses the adsorption force and drops from the inner surface of the cylinder to the material receiving groove 31 and slides towards the separation component under the action of its own gravity. When the drum 22 continues to rotate, the trigger arm 234 leaves the position of the dial block 235 and returns to the initial position under the action of the return spring 238.

[0037] Please refer to Figure 4 and Figure 5, in some embodiments, the deoxidizer separation device 30 further includes a separation assembly. The separation assembly includes a conveyor belt 32 correspondingly connected to the material receiving tank 31, a separation pressing plate 33 spanning opposite sides of the conveyor belt 32, and a separation wheel 34 located above the conveyor belt 32. The separation wheel 34 is disposed in front of the separation pressing plate 33 along the conveying direction of the conveyor belt 32. The conveyor belt 32 is used to convey the deoxidizer packets extracted by the magnetic attraction mechanism forward. The separation pressing plate 33 spans both sides of the conveyor belt 32 and applies resistance to the deoxidizer packets conveyed by the conveyor belt 32 to prevent the deoxidizer from moving together with the conveyor belt 32. Only the piece of deoxidizer that fits against the conveyor belt 32 can continue to be conveyed forward due to the frictional thrust of the conveyor belt 32. Due to the pressure of the separation pressing plate 33, the frictional thrust of the conveyor belt 32 on the deoxidizer will increase, and it can overcome the resistance of the separation pressing plate 33 and continue to be conveyed forward. The separation wheel 34 is located above the conveyor belt 32, and the relative movement direction of the separation wheel 34 and the conveyor belt 32 is opposite. The separation wheel 34 pushes the deoxidizer conveyed by the conveyor belt 32 in the opposite direction. Only the piece of deoxidizer that fits against the conveyor belt 32 can overcome the reverse thrust of the separation wheel 34 and continue to be conveyed forward due to the frictional thrust of the conveyor belt 32, so as to completely separate the deoxidizer that has not been completely separated by the separation pressing plate 33 and ensure that only one piece of deoxidizer can be output each time.

[0038] In some embodiments, the separation assembly further includes a torsion spring 332, a pressing plate adjusting member 335, and a mounting shaft 334 that cooperate with the separation pressing plate 33. The mounting shaft 334 is connected to the side plates on opposite sides of the material receiving groove 31. The separation pressing plate 33 is rotatably connected to the mounting shaft 334. The pressing plate adjusting member 335 is adjustably locked on the mounting shaft 334. The first end of the torsion spring 332 abuts against the separation pressing plate 33, and the second end abuts against the pressing plate adjusting member 335. Optionally, the separation assembly further includes a separation wheel adjusting member 341 and an adjusting bolt assembly 342. The first end of the separation wheel adjusting member 341 is connected to the mounting shaft 334 of the separation pressing plate 33, and the second end is connected to the drive shaft 340 of the separation wheel 34. The adjusting bolt assembly 342 abuts against the second end of the separation wheel adjusting member 341 to adjust the separation wheel adjusting member 341 to rotate around the mounting shaft 334 and change the distance between the separation wheel 34 and the conveyor belt 32. The pressing plate adjusting member 335 is adjustably locked on the mounting shaft 334. The torsion spring 332 is sleeved on the mounting shaft 334, and the two ends of the torsion spring 332 respectively abut against the separation pressing plate 33 and the pressing plate adjusting member 335. Thus, by adjusting the locking position of the pressing plate adjusting member 335 on the mounting shaft 334, the relative positions of the first end and the second end of the torsion spring 332 can be changed, thereby changing the elastic force exerted by the torsion spring 332 on the separation pressing plate 33, and further changing the magnitude of the resistance exerted on the deoxidizer conveyed by the conveyor belt 32. The resistance exerted by the separation pressing plate 33 on the deoxidizer conveyed by the conveyor belt 32 is adjusted to a suitable value, which not only ensures the smooth conveyance of the deoxidizer sheet in contact with the conveyor belt 32, but also prevents the separation of other superimposed deoxidizers. Among them, the first end of the separation wheel adjusting member 341 is installed on the mounting shaft 334 and can rotate around the mounting shaft 334. The drive shaft 340 is rotatably installed at the second end of the separation wheel adjusting member 341. The adjusting bolt assembly 342 abuts against the second end of the separation wheel adjusting member 341. By adjusting the adjusting bolt assembly 342, the separation wheel adjusting member 341 can be rotated around the mounting shaft 334 to change the position of the drive shaft 340 relative to the conveyor belt 32, thereby changing the relative position between the separation wheel 34 and the conveyor belt 32. The relative position between the separation wheel 34 and the conveyor belt 32 is adjusted to a suitable value, which not only ensures the smooth passage of the deoxidizer sheet in contact with the conveyor belt 32, but also prevents the passage of other superimposed deoxidizers and separates them.

[0039] Optionally, the separation component further includes a driving shaft 351 connected to the conveyor belt 32, a separation motor 352, a transmission structure connected between the separation motor 352 and the driving shaft 351, and an elastic conveyor belt 353 connected between the driving shaft 340 of the separation wheel 34 and the driving shaft 351. Since the central position of the driving shaft 340 of the separation wheel 34 can be adjusted while the central position of the driving shaft 351 of the conveyor belt 32 is fixed, the elastic conveyor belt 353 can adapt to a certain degree of relative position change without affecting the transmission.

[0040] Optionally, the deoxidizer feeding system further includes a feeding device 40. The feeding device 40 includes a temporary storage tank 440 correspondingly connected to the material receiving tank 31, a baffle door 441 disposed in the temporary storage tank 440, and a driving member 442 for driving the baffle door 441 to open or close. When the baffle door 441 is opened, the deoxidizer packets located in the temporary storage tank 440 slide out under the action of gravity and fall to the target position. The roller motor drives the roller 22 to rotate through a transmission mechanism, and the transmission mechanism can be a synchronous belt, a chain, a gear, or the like. The driving member 442 can be a pushing cylinder for driving the baffle door 441 to open or close. When the baffle door 441 is opened, the deoxidizer in the temporary storage tank 440 slides out of the temporary storage tank 440 under its own gravity and is fed to the target position. Optionally, the deoxidizer feeding system further includes a first group of sensors and a second group of sensors. The first group of sensors is located at the conveyor belt 32 for sensing whether the deoxidizer reaches the conveyor belt 32, and the second group of sensors is located at the temporary storage tank 440 for sensing whether the deoxidizer reaches the temporary storage tank 440.

[0041] The deoxidizer feeding system provided by the embodiment of the present application at least has the following characteristics:

[0042] First, the deoxidizer feeding system includes a frame 10, a roller 22, a supporting roller 11 for supporting the roller 22, a roller motor for driving the roller 22 to rotate, a magnetic attraction mechanism disposed on the outer periphery of the roller 22, a material receiving tank 31 for receiving the deoxidizer extracted by the magnetic attraction mechanism, a separation device 30 for further separating the deoxidizer in the material receiving tank 31, and a feeding device 40 for caching and feeding one by one the deoxidizer separated by the separation device 30. The overall structure of the deoxidizer feeding system is compact and has a synergistic effect, enabling efficient and accurate feeding of the deoxidizer.

[0043] Second, the magnetic attraction mechanism includes multiple magnetic attraction components. The number of magnetic attraction components corresponds to the number of multi-sided cylinders and is respectively arranged on each side surface of the cylinder. The magnetic attraction component includes a magnetic attraction shaft 232 installed on the bottom plates at both ends, a magnetic attraction mounting block 233 fixedly installed on the magnetic attraction shaft 232, a magnetic attraction piece 231 arranged on the magnetic attraction mounting block 233, a trigger arm 234 fixedly connected to the magnetic attraction shaft 232, and a return spring 238. By means of a stop block installed on the frame 10 to block and trigger the trigger arm 234, precise control of the magnetic attraction mechanism for adsorbing and discharging the deoxidizer is achieved;

[0044] Third, within each group of magnetic attraction components, the magnetic attraction shaft 232, the magnetic attraction mounting block 233, and the magnetic attraction piece 231 are correspondingly arranged with the material receiving groove 31 in the deoxidizer separation device 30. Each group of magnetic attraction components further includes a swing arm 236 fixedly connected to each magnetic attraction shaft 232 respectively, and a connecting rod 237 connecting multiple swing arms 236 together. When the trigger arm 234 drives one of the magnetic attraction shafts 232 to rotate, the other magnetic attraction shafts 232 in the same group are driven to rotate by the same angle and in the same direction through the swing arms 236 and the connecting rod 237, improving the deoxidizer discharging efficiency.

[0045] The method for the deoxidizer discharging system to discharge the deoxidizer mainly includes the following steps:

[0046] S11, the magnetic attraction mechanism adsorbs the deoxidizer on the inner surface of the drum 22. As the drum 22 rotates to the uppermost position, the magnetic attraction mechanism is triggered, and the deoxidizer loses its adsorption force and drops from the inner surface of the drum 22 to the material receiving groove 31, and slides to the deoxidizer separation device 30 under the action of gravity;

[0047] S12, after being separated by the deoxidizer separation device 30, the deoxidizer reaches the discharging device 40. At the same time, the magnetic attraction mechanism extracts the next group of deoxidizers from the drum 22 and transfers them to the deoxidizer separation device 30

[0048] S13, the discharging device 40 discharges the temporarily stored deoxidizer to the target position. At the same time, the separation device 30 separates the next group of deoxidizers and reaches the discharging device 40;

[0049] The above is repeated in a cycle.

Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
