Description

TECHNICAL FIELD

[0001] The application is a dehumidification bag packing machine and its packing method, belonging to the field of dehumidification bag packing machines. BACKGROUND

[0002] The dehumidification bag is a desiccant product for absorbing moisture in a closed space, mainly used for moisture and mildew prevention in small range environments such as wardrobes, shoe cabinets, and car interiors.

[0003] The dehumidification bag packing machine is a packaging equipment specially used for automatic production of dehumidification bags, which encapsulates the moisture-absorbing material into a bagged product through precise metering, filling, and sealing processes.

[0004] Before the dehumidification bag packing machine performs the discharging work, manual or mechanical arm is used to carry batches of bagged dehumidification particles to the discharging end of the dehumidification bag packing machine. After opening the bagged dehumidification particles, the dehumidification particles are directly introduced into the discharging end of the dehumidification bag packing machine. Due to batch differences in batches of bagged dehumidification particles, sampling and detection work is required for quality control.

[0005] The existing sampling and detection work uses the method of opening the bagged dehumidification particles and then operating the detection instrument by the staff to detect each bag, which is relatively inconvenient and can easily affect the work progress of the dehumidification bag packing. SUMMARY

[0006] In view of the deficiencies of the prior art, the application aims to provide a dehumidification bag packing machine and its packing method to solve the problem that the existing sampling and detection work uses the method of opening the bagged dehumidification particles and then operating the detection instrument by the staff to detect each bag, which is relatively inconvenient and can easily affect the work progress of the dehumidification bag packing.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dehumidifying bag filling machine, comprising a positioning frame, a dehumidifying bag conveying unit, a feeding cylinder, and an intelligent guiding unit; the dehumidifying bag conveying unit is located inside the bottom of the positioning frame; the feeding cylinder is located on the top surface of the positioning frame; the intelligent guiding unit is located on the top surface inside the positioning frame, with its top end connected to the output end of the feeding cylinder and its bottom end connected to the dehumidifying bag conveying unit, thereby guiding the dehumidifying particles input from the feeding cylinder into the dehumidifying bags conveyed on the dehumidifying bag conveying unit; the intelligent guiding unit includes an active unblocking hopper, an intelligent discharging component, and a filling cylinder; the active unblocking hopper is located on the upper end of the intelligent discharging component, and the intelligent discharging component is located on the upper end of the filling cylinder; the intelligent discharging component includes a discharging seat, a discharging nozzle located on the bottom surface of the discharging seat and connected to the inlet of the filling cylinder, and a discharging passage located within the discharging seat. The discharge channel extends through the top surface of the discharge seat at one end and connects to the output end of the active unblocking hopper, while the other end connects to the discharge nozzle. One inner wall of the discharge channel has a slope, on which a sampling channel is inclinedly connected. A telescopic groove is provided at the inlet of the sampling channel, and a sealing block that movably closes the inlet of the sampling channel is installed within the telescopic groove. The bottom surface of the discharge seat has a sampling detection structure connected to the outlet of the sampling channel and a driving structure that drives the sealing block to move up and down. The sampling detection structure includes an internally threaded assembly groove connected to the outlet of the sampling channel and located at the edge of the bottom surface of the discharge seat, a sampling can with its upper thread connected to the internally threaded assembly groove, and several sensors located on one side of the internally threaded assembly groove. The sampling can has its opening facing upwards and connected to the sampling channel. The outer wall of the sampling can has detection holes adapted to the sensor detection ends, allowing the sensors to detect the dehumidifying particles inside the sampling can through the detection holes.

[0008] Furthermore, to prevent the dehumidifying particles from clogging during the feeding process, the active unblocking hopper includes a hopper body, a feeding pipe, a sealing disc, and a connecting pipe. The feeding pipe is located at the bottom of the hopper body and connects to the discharge channel. The sealing disc is fixedly nested inside the top opening of the hopper body. The connecting pipe runs vertically through the center of the sealing disc, and its top end connects to the output end of the discharge cylinder. The bottom surface of the sealing disc has an annular drive groove connected to the lower part of the connecting pipe. A magnetic ring is movably mounted in the annular drive groove. The lower outer wall of the connecting pipe has an annular limiting groove that slides with the magnetic ring. A flexible unblocking strip is mounted on the bottom surface of the magnetic ring. The lower inner wall of the hopper body has a positioning tube connected to the top of the feeding pipe. The lower part of the flexible unblocking strip is movably embedded in the positioning tube. The top surface of the inner wall of the annular drive groove has an electromagnet that generates a repulsive force against the magnetic ring and a return spring connected to the magnetic ring.

[0009] Furthermore, in order to prevent the dehumidifying particles falling into the hopper body from bouncing up and entering the annular drive groove, thus affecting the transmission operation of the magnetic ring, the bottom opening of the annular drive groove is detachably sealed with a cover plate. The cover plate has positioning holes at the center and the edges. The positioning hole at the center is connected to the connecting pipe, and the positioning hole at the edge is movably connected to the flexible unblocking strip.

[0010] Furthermore, in order to detect the humidity or size of the dehumidifying particles, the sensor is either a humidity sensor or an optical sensor.

[0011] Furthermore, in order to improve the sealing performance and prevent it from affecting the detection work, the sampling can opening, the sampling channel, and the inner side of the sealing block form a closed detection chamber, and a sealing strip that contacts the sealing block is provided at the inlet of the sampling channel.

[0012] Furthermore, to prevent interference with the discharge of dehumidifying particles, the outer side of the enclosed block is flush with the slope of the discharge channel.

[0013] Furthermore, in order to improve driving efficiency, the driving structure includes a driving groove located at the center of the bottom surface of the discharge seat and a linear driver fixedly installed in the driving groove. The output end of the linear driver faces upward and extends movably into the telescopic groove to connect with the bottom surface of the closed block.

[0014] Furthermore, a valve structure is provided at the outlet of the discharge nozzle to control the output of dehumidifying particles.

[0015] A bagging method for a dehumidifying bag bagging machine, derived from the operation of the dehumidifying bag bag bagging machine, includes the following steps: Step S1: The staff or robotic arm transports a batch of bagged dehumidifying granules to the top of the positioning frame. After opening the bagged dehumidifying granules, they are fed into the feeding cylinder. The dehumidifying granules enter the intelligent feeding unit from the feeding cylinder. In step S2, the dehumidifying particles first enter the active unblocking hopper in the intelligent feeding unit. Under the positioning of the connecting pipe, they enter the hopper body and are then fed into the intelligent discharge component through the feeding pipe. During this process, the electromagnet will operate intermittently. When it operates, it generates a repulsive force on the magnetic ring, causing the magnetic ring to move vertically downward along the annular limiting groove. The return spring is stretched and deformed, and the magnetic ring will drive the flexible unblocking strip to slide in the positioning tube. The bottom end of the flexible unblocking strip will extend out from the bottom opening of the positioning tube and enter the feeding pipe. After the electromagnet is de-energized, the return spring resets, and the magnetic ring drives the flexible unblocking strip to retract into the positioning tube. Under the reciprocating action of the flexible unblocking strip, the dehumidifying particles in the feeding pipe are unblocked, effectively preventing blockage. Step S3: The dehumidifying particles enter the discharge channel of the intelligent discharge component through the guide pipe, and then are quantitatively fed into the bagging cylinder through the discharge nozzle. Finally, the bagging cylinder guides the dehumidifying particles into the dehumidifying bag in the dehumidifying bag conveying unit to complete the bagging work. Step S4: When staff need to sample and test unbagded dehumidifying particles, the linear actuator quickly drives the sealing block to move up and down. The sealing block first moves down to the bottom of the telescopic groove, releasing the inlet of the sampling channel. A small amount of dehumidifying particles will enter the sampling channel. Then, the sealing block moves up to re-close the inlet of the sampling channel, and the dehumidifying particles will eventually fall into the sampling tank. The sensor detects the dehumidifying particles in the sampling tank through the detection hole, and the detected data is transmitted to the control center. Subsequently, the staff unscrews the sampling tank out of the internal threaded assembly groove, pours out the dehumidifying particles that have been tested in the sampling tank for recycling, and finally puts the sampling tank back into the internal threaded assembly groove for the next sampling and testing work.

[0016] The beneficial effects of this invention are: an intelligent feeding unit with sampling and detection function is set on the dehumidifying bag filling machine. The intelligent discharge component in the intelligent feeding unit can complete the sampling and detection work during the feeding process, eliminating the need to sample and detect each bag of dehumidifying granules one by one before the feeding work, which effectively improves the convenience of sampling and detection work and prevents it from affecting the progress of dehumidifying bag filling.

It has bending properties and, being wrapped in a plastic sleeve, will not cause the dehumidifying granules to break.

[0024] To prevent dehumidifying particles falling into the hopper body 411 from bouncing up and entering the annular drive groove 4131, thus affecting the transmission operation of the magnetic ring 4132, the bottom opening of the annular drive groove 4131 is detachably sealed with a cover plate 4136.

[0026] To improve the convenience of sampling, the sampling and detection structure includes an internally threaded assembly groove 4213 connected to the outlet of the sampling channel 424 and located at the bottom edge of the discharge seat 421, a sampling can 4214 with its upper thread connected to the internally threaded assembly groove 4213, and several sensors 4215 located on one side of the internally threaded assembly groove 4213.

[0028] To improve sealing performance and prevent interference with testing, the opening of the sampling container 4214, the sampling channel 424, and the inner side of the sealing block 426 form a closed testing chamber. The inlet of the sampling channel 424 is provided with a sealing strip that contacts the sealing block 426.

[0029] To prevent interference with the discharge of dehumidifying particles, the outer side of the sealing block 426 is flush with the slope of the discharge channel 423.

[0030] To improve driving efficiency, the driving structure includes a driving groove 4211 located at the center of the bottom surface of the discharge seat 421 and a linear driver 4212 fixedly installed in the driving groove 4211. The output end of the linear driver 4212 faces upward and extends movably into the telescopic groove 425 to connect with the bottom surface of the closed block 426.

[0033] A bagging method for a dehumidifying bag bagging machine, derived from the operation of the dehumidifying bag bag bagging machine, includes the following steps: Step S1: The staff or robotic arm transports a batch of bagged dehumidifying granules to the top of the positioning frame 1. After opening the bagged dehumidifying granules, they are fed into the feeding cylinder 3. The dehumidifying granules enter the intelligent feeding unit 4 from the feeding cylinder 3. In step S2, the dehumidifying particles first enter the active unblocking hopper 41 in the intelligent feeding unit 4, and then enter the hopper body 411 under the positioning of the connecting pipe 414. They are then fed into the intelligent discharge component 42 through the feeding pipe 412. During this process, the electromagnet 4134 operates intermittently, generating a repulsive force on the magnetic ring 4132, causing the magnetic ring 4132 to move vertically downwards along the annular limiting groove 4141. The return spring 4135 stretches and deforms, causing the magnetic ring 4132 to... The flexible drain strip 4133 slides inside the positioning tube 4111. The bottom end of the flexible drain strip 4133 extends out from the bottom opening of the positioning tube 4111 and enters the guide tube 412. After the electromagnet 4134 is de-energized, the reset spring 4135 resets and drives the flexible drain strip 4133 to retract into the positioning tube 4111 through the magnetic ring 4132. Under the reciprocating action of the flexible drain strip 4133, the dehumidifying particles in the guide tube 412 are unblocked, effectively preventing blockage. In step S3, the dehumidifying particles enter the discharge channel 423 in the intelligent discharge component 42 through the guide pipe 412, and then are quantitatively fed into the bagging cylinder 43 through the discharge nozzle 422. Finally, the bagging cylinder 43 guides the dehumidifying particles into the dehumidifying bag conveying unit 2 to complete the bagging work. In step S4, when staff need to sample and test unbagded dehumidifying particles, the linear actuator 4212 quickly drives the sealing block 426 to move up and down. The sealing block 426 first moves down to the bottom of the telescopic groove 425, releasing the inlet of the sampling channel 424. A small amount of dehumidifying particles will enter the sampling channel 424. Then, the sealing block 426 moves up to re-close the inlet of the sampling channel 424. The dehumidifying particles will eventually fall into the sampling canister 4214. The sensor 4215 detects the dehumidifying particles in the sampling canister 4214 through the detection hole 4216. The detected data will be transmitted to the control center. Subsequently, the staff unscrews the sampling canister 4214 out of the internal threaded assembly groove 4213, pours out the dehumidifying particles that have been tested in the sampling canister 4214 for recycling, and finally puts the sampling canister 4214 back into the internal threaded assembly groove 4213 to carry out the next sampling and testing work.

The main focus here is on the structure that is different from other embodiments of the present invention. In order to efficiently detect the humidity of the dehumidifying particles, several sensors 4215 are humidity sensors.

Under the reciprocating action of the flexible drain strip (4133), the dehumidifying particles in the guide tube (412) are cleared, effectively preventing blockage. In step S3, the dehumidifying particles enter the discharge channel (423) of the intelligent discharge component (42) through the guide pipe (412), and then are quantitatively fed into the bagging cylinder (43) through the discharge nozzle (422). Finally, the bagging cylinder (43) guides the dehumidifying particles into the dehumidifying bag conveying unit (2) to complete the bagging work. Step S4: When staff need to sample and test the unbagded dehumidifying particles, the linear actuator (4212) quickly drives the sealing block (426) to move up and down. The sealing block (426) first moves down to the bottom of the telescopic groove (425), releasing the inlet of the sampling channel (424). A small amount of dehumidifying particles will enter the sampling channel (424). Then the sealing block (426) moves up to re-close the inlet of the sampling channel (424), and the dehumidifying particles will eventually fall into the sampling tank (425). Inside 214), the sensor (4215) detects the dehumidifying particles in the sampling tank (4214) through the detection hole (4216). The detected data is transmitted to the control center. Subsequently, the staff unscrews the sampling tank (4214) out of the internal thread assembly groove (4213), pours out the dehumidifying particles that have been detected in the sampling tank (4214) for recycling, and finally puts the sampling tank (4214) back into the internal thread assembly groove (4213) so that the next sampling and testing work can be carried out.
