Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hemodialysis concentrate production, and particularly relates to a hemodialysis concentrate bottle aluminum foil sealing system. BACKGROUND

[0002] Dialysate is a kind of liquid that is needed to help the solute exchange through diffusion on both sides of the dialysis membrane during hemodialysis, and is generally prepared and stored in the form of concentrate. During the production and manufacturing of dialysate, concentrate is often used for preparation, so the storage and movement of hemodialysis concentrate often require very strict storage requirements. Therefore, the preparation of hemodialysis concentrate generally uses special bottles for storage and movement. When loading hemodialysis concentrate, the handle of such a bottle is generally upward to facilitate overall handling. In order to ensure the sealing of the bottle during storage, the hemodialysis concentrate is generally sealed with aluminum foil at the bottle opening after production and manufacturing, so as to facilitate the handling, logistics movement and sealed storage of hemodialysis concentrate.

[0003] After loading the hemodialysis concentrate, the hemodialysis concentrate bottle is generally manually sent to the conveying belt assembly and sealed with aluminum foil at the bottle opening by using a heat sealing structure. However, during actual heat sealing of the bottle opening, the hemodialysis concentrate bottle continuously moves with the conveying belt, and the heat sealing position is often unstable. The quality of aluminum foil sealing of the bottle opening is generally poor. If the conveying belt is stopped at a fixed point, the bottle body may be tilted due to inertia, resulting in spilling of the liquid in the bottle.

DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments. The embodiments in the application and the features in the embodiments can be combined with each other without conflict. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the application.

[0049] In the embodiments, refer to Figures 1 to 11 .

[0050] As Figures 1 to 3As shown, the present application provides a hemodialysis concentrate bottle mouth aluminum foil sealing system, comprising a conveyor belt 1 and a sealing mechanism 3 arranged on the conveyor belt 1, the sealing mechanism 3 comprising:

[0051] A housing 31 is arranged on the conveyor belt 1, the housing 31 is provided with through holes on both sides, and the housing 31 is provided with a first triangular block 33 and a second triangular block 34 with opposite inclined surfaces for blocking the movement of the hemodialysis concentrate bottle in the through hole;

[0052] A turnover plate assembly 32 is arranged in the through hole of the housing 31 for blocking the hemodialysis concentrate bottle from entering the housing 31;

[0053] A moving plate assembly 38 is arranged on the second triangular block 34 and slides along the length direction of the conveyor belt 1, and when the hemodialysis concentrate bottle contacts the moving plate assembly 38 and moves synchronously, the moving plate assembly 38 drives the turnover plate assembly 32 to operate;

[0054] A heat sealing mechanism 39 is arranged on the moving plate assembly 38 for sealing the bottle mouth of the hemodialysis concentrate bottle contacting the moving plate assembly 38.

[0055] In specific implementation, the hemodialysis concentrate bottle is placed on the conveyor belt 1 by manual feeding, and the hemodialysis concentrate bottle can be sent into the sealing mechanism 3 for sealing by the conveyor belt 1, and when the hemodialysis concentrate bottle enters the housing 31 through the conveyor belt 1, it can drive the moving plate assembly 38, at this time, since the turnover plate assembly 32 and the moving plate assembly 38 are connected, the hemodialysis concentrate bottle can synchronously drive the turnover plate assembly 32 to operate when moving in the housing 31 through the conveyor belt 1, and the next hemodialysis concentrate bottle on the conveyor belt 1 can be blocked from entering the housing 31, which facilitates independent detection of the hemodialysis concentrate bottle and prevents the next hemodialysis concentrate bottle from moving with the conveyor belt 1 when the conveyor belt 1 is manually fed too much at one time, which can affect the heat sealing of the hemodialysis concentrate bottle, and can adjust the moving interval of the hemodialysis concentrate bottle between heat sealing, which facilitates process management, and when the hemodialysis concentrate bottle moves to the opposite inclined surfaces of the first triangular block 33 and the second triangular block 34, it can be fixed in position under stress, and the first triangular block 33 and the second triangular block 34 can cooperate with the conveyor belt 1 to limit and clamp the hemodialysis concentrate bottle, preventing the bottle mouth from shaking during sealing, which can cause unstable heating during aluminum foil heat sealing and affect the sealing quality, and the above can determine the position of the bottle body when the moving plate assembly 38 and the hemodialysis concentrate bottle move synchronously, which facilitates the aluminum foil heat sealing of the heat sealing mechanism 39.

[0056] It should be noted that firstly, the above-mentioned aluminum foil seal is completed by placing an aluminum foil of corresponding size at the bottle opening, tightening the bottle cap, and then heating by an external electromagnetic coil to melt the adhesive layer on the aluminum foil, so that the aluminum foil is fixed at the bottle opening. It belongs to the prior art, so its specific working principle and supporting use mode will not be described here. Secondly, the above-mentioned conveying belt 1 is always in running state, which facilitates continuous feeding while ensuring control of the fixed blood dialysis concentrate bottle for aluminum foil heat sealing, and is convenient to use.

[0057] In addition, as shown in Figure 1 and Figure 2 , it also includes a buffer pipe 2 arranged on the conveying belt 1 for limiting the movement of the blood dialysis concentrate bottle when it is blocked by the turnover plate assembly 32. Cooperating with the turnover plate assembly 32, it can retain the next blood dialysis concentrate bottle to be sealed with aluminum foil, facilitate the control of the blood dialysis concentrate bottle to enter the shell 31 independently for aluminum foil heat sealing of the bottle opening, facilitate independent detection of the blood dialysis concentrate bottle, prevent the next blood dialysis concentrate bottle from moving with the conveying belt 1 when the conveying belt 1 is manually fed too much at one time, and affect the heat sealing of the blood dialysis concentrate bottle, adjust the movement interval of the blood dialysis concentrate bottle between heat sealing, facilitate process management, and is safe and practical.

[0058] As shown in Figure 3 , the first triangular block 33 and the second triangular block 34 are both arranged as right triangles, and the inclined surfaces of the first triangular block 33 and the second triangular block 34 are both in contact with the outer surface of the blood dialysis concentrate bottle for blocking the movement of the blood dialysis concentrate bottle. The first triangular block 33 and the second triangular block 34 are connected to the shell 31 by a plurality of first electric telescopic rods 35.

[0059] In specific implementation, the movement of the blood dialysis concentrate bottle can be driven by the operation of the conveying belt 1, and the positions of the inclined surfaces of the first triangular block 33 and the second triangular block 34 are adjusted to the conveying belt 1. When the inclined surfaces of the first triangular block 33 and the second triangular block 34 are both in contact with the outer surface of the blood dialysis concentrate bottle, the position of the blood dialysis concentrate bottle is fixed. At this time, the heat sealing mechanism 39 on the moving plate assembly 38 can be used to perform heat sealing operation on the bottle opening of the blood dialysis concentrate bottle. After the sealing is completed, the first electric telescopic rod 35 can be used to control the movement of the first triangular block 33 and the second triangular block 34, so that the inclined surfaces of the first triangular block 33 and the second triangular block 34 are away from the outer surface of the blood dialysis concentrate bottle, and the moving plate assembly 38 and the blood dialysis concentrate bottle are separated. At this time, the blood dialysis concentrate bottle continues to move with the conveying belt 1 and enters the next process.

[0060] It should be noted that first, the above-mentioned first electric telescopic rod 35 is set to reciprocate, and the first electric telescopic rod 35 is always in an elongated state under normal conditions, but reciprocates once after the heat sealing is completed, secondly, the first electric telescopic rod 35 can also be replaced by other reciprocating structures, in addition, since the first electric telescopic rod 35 is prior art, therefore its internal working principle will not be described here, and the existing technical structure of the electric telescopic rod can be directly used.

[0061] As shown in Figure 6 , the moving plate assembly 38 includes a moving plate body 386 vertically arranged to contact the hemodialysis concentrate bottle, a limiting sliding groove 381 opened on the second triangular block 34, a limiting sliding block 382 sliding in the limiting sliding groove 381 for connecting the moving plate body 386, a connecting plate 383 arranged on the second triangular block 34 in a bent shape, a second telescopic rod 385 arranged on the connecting plate 383 for connecting the moving plate body 386 to move, and a connecting spring 384 sleeved outside the second telescopic rod 385, and the heat sealing mechanism 39 is installed at the top end of the moving plate body 386.

[0062] In specific implementation, when the hemodialysis concentrate bottle contacts the moving plate body 386 and moves synchronously, the moving plate body 386 can be limited to slide on the second triangular block 34 through the limiting sliding block 382 and the limiting sliding groove 381, and cooperates with the arrangement of the connecting spring 384 and the second telescopic rod 385, when the hemodialysis concentrate bottle sealing is completed and enters the next stage, the moving plate body 386 is separated from the hemodialysis concentrate bottle, the moving plate body 386 is reset by the connecting spring 384, and then drives the turnover plate assembly 32 to drive the next hemodialysis concentrate bottle on the conveying belt 1 to enter the shell 31 for aluminum foil sealing operation.

[0063] As shown in Figure 4 and Figure 5 , the turnover plate assembly 32 includes a turnover plate body 321 rotating in the through hole of the shell 31, a connecting gear 323 arranged inside the shell 31 for rotation, a connecting belt wheel 322 arranged inside the shell 31 for connecting the turnover plate body 321 and the connecting gear 323 to rotate synchronously, a rack 324 meshing with the connecting gear 323, a sliding rail structure 325 arranged on the rack 324 for limiting the movement of the rack 324 in the shell 31, and a first telescopic rod 326 arranged on the rack 324 for connecting the moving plate assembly 38 to move synchronously.

[0064] In specific implementation, when the mobile plate assembly 38 and the hemodialysis concentrate bottle are attached and moved, the first telescopic rod 326 can drive the rack 324 to move, and since the rack 324 and the connecting gear 323 are in meshing relationship, the connecting belt wheel 322 coaxial with the connecting gear 323 can be driven to rotate, thereby driving the turnover plate main body 321 to turn inwardly into the shell 31.

[0065] It should be noted that the above-mentioned connecting belt wheel 322 belongs to the prior art in the mechanical field, which is composed of a driving gear, a transmission gear and a connecting belt connecting the two gears, and the specific principle and mode of use will not be described here.

[0066] In addition, as shown in Figure 7 and Figure 8 , the heat sealing mechanism 39 includes a mounting plate 391 horizontally arranged on the mobile plate assembly 38 and two groups of heat sealing assemblies arranged before and after the conveying belt 1 in the transmission direction at the bottom of the mounting plate 391.

[0067] The two groups of heat sealing assemblies are separately driven and can be used for heat sealing operation on the opposite placed hemodialysis concentrate bottle mouth.

[0068] Among them, the heat sealing assembly includes a heating plate 394 for coil electromagnetic induction heating of the aluminum foil of the hemodialysis concentrate bottle mouth, a plurality of second electric telescopic rods 396 arranged on the heating plate 394 for connecting the mounting plate 391, a main machine 392 arranged at the top end of the heating plate 394, and a terminal post 393 for connecting the main machine 392 and the heating plate 394, and a heat insulation baffle 395 arranged at the bottom of the heating plate 394 on both sides.

[0069] In specific implementation, the heating plate 394 can be controlled to move downward to the bottle mouth for sealing operation by the second electric telescopic rod 396.

[0070] It should be noted that the above-mentioned coil electromagnetic induction heating of the aluminum foil of the bottle mouth by the terminal post 393 connecting the main machine 392 and the heating plate 394 and the heat insulation baffle 395 arranged at the bottom of the heating plate 394 on both sides belongs to the existing disclosed technology (Chinese patent application No. 202011604715.X: Invention application: Packaging bottle aluminum foil sealing machine and sealing method), and the specific principle and structure will not be described here.

[0071] Meanwhile, as shown in Figure 3 , Figure 4 and Figure 11 , the infrared scanner 37 is arranged inside the shell 31 at the position where the hemodialysis concentrate bottle mouth is flush, and the detection module 371 for scanning the hemodialysis concentrate bottle mouth when the hemodialysis concentrate bottle stops moving is arranged inside the infrared scanner 37.

[0072] It should be noted that the infrared scanner 37 is a publicly disclosed technology, mainly used to collect the planar scanning image of the hemodialysis concentrate bottle opening when the hemodialysis concentrate bottle opening position stops, and the existing infrared scanner 37 can be directly used. The specific principle and structure will not be described here.

[0073] As shown in the specific implementation Figure 9 The shell 31 is provided with a processing computer 36 for driving the electrical structure of the system to operate. The processing computer 36 is internally provided with a timing module 361, a judgment module 362 and a driving module 363, wherein:

[0074] The driving module 363 is used to control the electrical structure of the system, which can be mainly used to drive the operation of the electric telescopic rod and the heat sealing structure;

[0075] The judgment module 362 is used to receive the scanning image data of the detection module 371 and make a judgment on the bottle opening position. According to the judgment structure, the heat sealing mechanism 39 is controlled to operate to seal the aluminum foil on the hemodialysis concentrate bottle opening;

[0076] The timing module 361 is used to calculate the time when the hemodialysis concentrate bottle stops moving, and when the stop moving time reaches 1.5S, the judgment module 362 is operated.

[0077] More specifically, by setting the infrared scanner 37 at the bottle opening position of the hemodialysis concentrate bottle, the length of the scanning image can be used to analyze the direction of the hemodialysis concentrate bottle opening during feeding, and the electric telescopic rod of the heat sealing mechanism 39 is used to control the operation of different heat sealing components to accurately align the hemodialysis concentrate bottle opening and perform aluminum foil heat sealing, preventing the bottle opening from being sealed due to the opposite position of the bottle opening during manual feeding, and facilitating use.

[0078] In addition, the specific judgment method of the judgment module 362 in the above processing computer 36 for judging the bottle opening position is as shown in Figure 10 , which includes:
