Description

Technical Field

[0001] The present invention relates to the technical field of packaging devices, and in particular to a packaging device for processing microbial inoculants. Background Art

[0002] After the production of microbial inoculants is completed, they need to be packaged. For example, the patent announcement number is CN221114413U, which is a microbial inoculant packaging equipment, including a base, a filling structure installed on the top of the base, and the filling structure includes: a support frame, a material barrel, a driving member, a stirring blade, a first control valve, a fixing frame, two lifting components, a transfer cylinder, a lifting seat, a connecting pipe, a filling pipe and a dust removal component. The driving member is used to drive the stirring blade to rotate to prevent the material from agglomerating. Then the material will enter the transfer cylinder through the first control valve for temporary storage. At this time, the operator can observe and regulate the amount of material entering the transfer cylinder. Then, the two lifting components can be controlled to operate so that the bottom of the filling tube is close to the packaging barrel or packaging bag placed on the top of the disc, and the filling operation can be performed. The floating objects generated in the process are collected by the collecting component, which has the characteristics of high packaging efficiency and good packaging effect.

[0003] After the packaging of liquid microbial inoculants is completed, since it is generally in the form of filling, some liquid will fall when the filling is stopped. At this time, directly transferring the packaging barrel will cause the liquid to fall onto the conveyor belt, causing waste of the inoculant and contaminating the packaging equipment. If the waste and contamination of the inoculant are to be avoided, extra time will be required to wait for the current inoculant to fall completely, but the packaging efficiency will be affected. For this reason, the present application designs a packaging device for processing microbial inoculants, which can temporarily recover the inoculant that is about to fall when the packaging is completed, thereby improving the efficiency of continuous packaging while ensuring that the inoculant will not be wasted.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By starting the micro negative pressure pump, negative pressure can be created inside the recovery pipe, and the residual liquid in the filling component can be recovered under negative pressure to avoid leakage of liquid after the filling component falls off the packaging can. By starting the first delivery pump, the liquid collected in the liquid storage tank can be transferred to the storage box through the reflux pipe to achieve complete recovery of the liquid. By starting the second delivery pump, the liquid in the storage box can be delivered from the delivery pipe to the filling component to achieve liquid supply. The above structure allows the present application to recover the residual liquid after completing a single filling to avoid liquid falling and leakage when transferring the packaging can.

[0016] 2. During filling, the filling tube first enters the package, and then the movable column descends to make the material control plug open the filling tube for filling. In order to avoid sucking liquid during filling, a closed baffle is provided at the bottom of the fitting receiving tube. When the material control plug is opened in place, the series hole will be aligned with it, thereby disconnecting the connection between the recovery channel and the fitting receiving tube, and realizing temporary closure of the recovery operation. If the filling is completed, the movable column will rise and reset the filling tube first and then reset. During this process, the series hole will be connected with the fitting receiving tube, thereby realizing the liquid recovery operation. Recovery can be carried out without complete reset, which greatly reduces the packaging efficiency.

[0017] 3. During recovery, the outer side of the material control plug is arc-shaped, so that the liquid will gather downward. During recovery, the recovery channel is in a negative pressure state, so that the reset spring contracts, and during the contraction of the reset spring, the conical block moves upward to open the conical opening, and then the liquid gathered downward is uniformly recovered. When the recovery is closed, the negative pressure state is released, and the reset spring will reset and support the conical block to block the conical opening.

[0018] 4. In order to ensure that the filling tube descends first and then the movable column descends, a support spring is arranged between the support ring and the stabilizing seat, so that the movable column is located on the upper side of the filling tube by default. Therefore, when the cylinder is pressed down, the filling tube is lowered first by the support of the support spring. When the matching supports on both sides of the filling tube are located at the bottom of the movable groove, the support spring will be compressed to push the movable column to descend again. When the movable column descends, the upper sealing part of the material control plug is away from the filling tube, and the filling operation is realized. Similarly, when the cylinder is reset, the support spring will first support the material control plug to reset and seal the lower end of the filling tube, and then the filling tube will reset upward.

[0019] 5. After the filling tube is filled and reset upward, the fitting baffle is located outside the filling tube, and the scraper will scrape the liquid on the surface of the filling tube downward, and part of the scraped liquid will fall into the package and the other part will gather at the bottom of the material control plug for recovery, thereby avoiding the situation where liquid remains after the packaging is completed. The buffer spring can be used for buffering when the fitting baffle is fitted downward with the packaging port to avoid deformation of the packaging due to pressure. The fitting baffle can avoid liquid leakage during the filling process. BRIEF DESCRIPTION OF THE DRAWINGS

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 making creative work are within the scope of protection of the present invention.

[0025] By starting the micro negative pressure pump 302, negative pressure can be created inside the recovery pipe 303, and the residual liquid in the filling component 4 can be recovered under negative pressure to avoid leakage of liquid after the filling component 4 falls off the packaging can. By starting the first delivery pump 501, the liquid collected in the liquid storage tank 301 can be transferred to the storage box 5 through the reflux pipe 304 to achieve complete recovery of the liquid. By starting the second delivery pump 502, the liquid in the storage box 5 can be delivered from the delivery pipe 6 to the filling component 4 to achieve liquid supply. The above structure allows the present application to recover the residual liquid after completing a single filling to avoid liquid falling and leakage when transferring the packaging can.

[0026] In this embodiment, the filling assembly 4 includes a housing 401, a connecting sleeve 402 is fixedly installed on the outer side of the housing 401, the connecting sleeve 402 is vertically movably installed inside the slide groove 201, a driving motor 202 is fixedly installed on the upper side of the column 2, and an adjusting screw 203 is fixedly installed on the output end of the driving motor 202, the adjusting screw 203 is located inside the slide groove 201 and is threadedly matched with the connecting sleeve 402; Movable grooves 407 are provided on both sides of the shell 401, and matching supports 4071 are movably provided inside the movable grooves 407. A filling tube 405 is installed between the matching supports 4071 on both sides. A stabilizing groove 4052 is provided on the upper side of the inner wall of the filling tube 405, and a movable column 406 is movably installed inside the stabilizing groove 4052. A material control plug 4061 is provided at the bottom of the movable column 406.

[0027] By starting the driving motor 202 to drive the adjusting screw 203 to rotate, and utilizing the limiting cooperation between the connecting sleeve 402 and the slide groove 201, the adjusting screw 203 and the connecting sleeve 402 are threadedly cooperated to achieve the height adjustment of the shell 401. Not only can it adapt to the height of the packaging can, but it can also ensure that the filling tube 405 can extend into the packaging can to avoid liquid splashing to the outside during filling.

[0028] In the present application, a delivery hose 601 is fixedly mounted on one side of the filling tube 405, and the delivery hose 601 passes through the corresponding matching support 4071 and is connected to the delivery tube 6; A fitting receiving tube 4053 is fixedly installed on the other side of the filling tube 405, a sealing ring 4055 is provided at one end of the fitting receiving tube 4053, a closing baffle 4054 is provided at the bottom of the fitting receiving tube 4053, a stabilizing sleeve 4057 is provided on the outside of the fitting receiving tube 4053, and the stabilizing sleeve 4057 is sleeved on the outside of the movable column 406.

[0029] It should be noted that a recovery channel 4062 is opened inside the movable column 406 , and a series hole 40611 is opened on one side of the movable column 406 . The series hole 40611 is communicated with the opening of the fitting receiving tube 4053 , and the series hole 40611 is communicated with the recovery channel 4062 .

[0030] During filling, the filling tube 405 first enters the package and then the movable column 406 descends to make the material control plug 4061 open the filling tube 405 for filling. In order to avoid liquid inhalation during filling, a closed baffle 4054 is provided at the bottom of the fitting receiving tube 4053. When the material control plug 4061 is opened into place, the series hole 40611 will be aligned with it, thereby disconnecting the connection between the recovery channel 4062 and the fitting receiving tube 4053, and realizing temporary closure of the recovery operation. If the filling is completed, the movable column 406 first rises to reset the filling tube 405 and then resets it. During this process, the series hole 40611 will be connected with the fitting receiving tube 4053, thereby realizing liquid recovery operation. Recovery can be carried out without complete resetting, which greatly reduces the packaging efficiency.

[0031] In the specific configuration, a conical opening 4064 is provided at the lower side of the inner part of the material control plug 4061 , and a recovery groove 4065 is provided at the upper side of the inner part of the material control plug 4061 , and the recovery groove 4065 is communicated with the recovery channel 4062 .

[0032] Among them, a cross bracket 4063 is fixedly installed between the recovery groove 4065 and the recovery channel 4062, a conical block 4066 is movably installed inside the conical opening 4064, a movable connecting rod 4067 is connected between the cross bracket 4063 and the conical block 4066, and a return spring 4068 is arranged inside the movable connecting rod 4067.

[0033] During recovery, the outer side of the material control plug 4061 is arc-shaped, so that the liquid will gather downward. During recovery, the recovery channel 4062 is in a negative pressure state, so that the return spring 4068 contracts, and during the contraction of the return spring 4068, the conical block 4066 moves up to open the conical opening 4064, and then the liquid gathered downward is recovered uniformly. When the recovery is closed, the negative pressure state is released, and the return spring 4068 will reset and support the conical block 4066 to block the conical opening 4064.

[0034] In the present application, a recovery hose 4056 is fixedly installed on the outside of the receiving tube 4053, and the recovery hose 4056 passes through the corresponding matching support 4071 to be connected to the recovery pipe 303. A return pipe 304 is arranged on the lower side of the liquid storage tank 301, and the lower end of the return pipe 304 is connected to the liquid inlet end of the first delivery pump 501.

[0035] When the liquid is recovered, it passes through the conical opening 4064, the recovery groove 4065, the recovery channel 4062, the series hole 40611 in sequence, and then enters the bonding receiving tube 4053. When the liquid is bonded to the receiving tube 4053, the recovery liquid is transferred to the recovery pipe 303 through the recovery hose 4056 to realize the recovery of the liquid.

[0036] In the present application, a support ring 4051 is provided on the upper side of the inner wall of the filling tube 405, a stabilizing seat 4069 is provided on the upper end of the movable column 406, the middle part of the stabilizing seat 4069 is slidably provided in the support ring 4051, and a support spring 40610 is installed between the upper side of the support ring 4051 and the upper side of the stabilizing seat 4069; An extension column 403 is fixedly mounted on the upper side of the housing 401 , a cylinder 4032 is mounted on the upper end of the extension column 403 via a mounting ring 4031 , and an output end of the cylinder 4032 is connected to a stabilizing seat 4069 .

[0037] In order to ensure that the filling tube 405 descends first and then the movable column 406 descends, a support spring 40610 is arranged between the support ring 4051 and the stabilizing seat 4069, so that the movable column 406 is located on the upper side of the filling tube 405 by default. Therefore, when the cylinder 4032 is pressed down, the filling tube 405 is lowered first by the support of the support spring 40610. When the matching supports 4071 on both sides of the filling tube 405 are located at the bottom of the movable groove 407, the support spring 40610 will be compressed to push the movable column 406 to descend again. When the movable column 406 descends, the upper sealing part of the material control plug 4061 is away from the filling tube 405, thus realizing the filling operation. Similarly, when the cylinder 4032 is reset, the support spring 40610 will first support the material control plug 4061 to reset and seal the lower end of the filling tube 405, and then the filling tube 405 will reset upward again.

[0038] In the present application, a plurality of grooves 404 are provided on the lower side of the shell 401, and a connecting plate 4042 is movably installed inside each groove 404 through a buffer spring 4041, a fitting baffle 4043 is fixedly installed on the lower end of the connecting plate 4042, and a scraper plate 4044 is provided on the lower surface of the fitting baffle 4043.

[0039] After the filling tube 405 completes filling and resets upward, the fitting baffle 4043 is located outside the filling tube 405, and the scraper plate 4044 will scrape the liquid on the surface of the filling tube 405 downward, and part of the scraped liquid will fall into the package and the other part will gather at the bottom of the material control plug 4061 to be recovered, thereby avoiding the situation where liquid remains after the packaging is completed. The buffer spring 4041 can be used to provide buffering when the fitting baffle 4043 is fitted downward with the packaging port to avoid deformation of the packaging due to pressure. The fitting baffle 4043 can be used to avoid liquid leakage during the filling process.

[0040] The working principle of the packaging device for processing microbial inoculants: When in use, the packaging cans to be filled are first placed on the conveyor belt 1, and then the conveyor belt 1 continuously transports the packaging; When the package is aligned with the filling assembly 4, the driving motor 202 is started to lower the fitting baffle 4043 to the package port to prevent leakage of liquid during the filling process; then the cylinder 4032 is started, and the filling tube 405 is first lowered by the support of the support spring 40610, and then pressed down again to make the upper sealing part of the material control plug 4061 away from the filling tube 405, wherein the pre-stored liquid can be directly discharged by the pressure storage tank 8, and the second delivery pump 502 is started to replenish the liquid to ensure the next round of use of the pressure storage tank 8; After filling, the cylinder 4032 is reset. During the reset process, the baffle plate 4043 is located outside the filling tube 405, and the scraper plate 4044 scrapes the liquid on the surface of the filling tube 405 downwards. Part of the scraped liquid falls into the package and the other part gathers at the bottom of the material control plug 4061 for recovery.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
