Description

Technical Field

[0001] This utility model relates to the field of hydrogel dressing packaging technology, and more specifically to a hydrogel dressing packaging machine. Background Technology

[0002] Hydrogel dressings are medical dressing kits with hydrogel as their core component, used for wound care. Their key feature is their ability to actively provide an ideal "moist healing" environment for the wound. Packaging for hydrogel dressings is mostly done using automated packaging machines. These machines typically have an extruder to pump the adhesive, a release liner or polyethylene backing to receive the hydrogel, and then, after the adhesive is cooled at low temperatures, it is sent to subsequent steps such as film covering, machine extrusion, and cutting.

[0003] According to patent publication number CN217893426U, published on 2022-11-25, a production and packaging device for hydrogel masks is disclosed. The hydrogel mask includes a release film and hydrogel. The device includes a frame, a conveying device, and a control system. The conveying device is mounted on the frame. Along the conveying direction of the conveying device, the frame is provided with, from back to front, a filling mechanism for adding liquid hydrogel, a forming mechanism for cooling liquid hydrogel, a film supply mechanism for wrapping the release film with hydrogel, a cutting mechanism for cutting and separating edge material, and a folding packaging machine for folding and packaging the hydrogel mask. The structure includes a conveying device comprising a first conveyor belt, which is correspondingly arranged with the folding packaging mechanism. The first conveyor belt includes a roller and three unit conveyor belts, which are equidistantly spaced on the roller. The folding packaging mechanism includes a pressure plate and two guide plates. The pressure plate presses against the unit conveyor belt located in the middle, and the two guide plates are distributed in the gaps on the left and right sides of the unit conveyor belt located in the middle. The control system is communicatively connected to the conveying device, the filling mechanism, the forming mechanism, the film supply mechanism, the cutting mechanism, and the folding packaging mechanism.

[0004] In the prior art, including the aforementioned patent, a dispensing mechanism is used to dispense hydrogels. The dispensing equipment typically employs a suction pump with piping and multiple conduits to guide the ends of the conduits toward the conveyor belt according to the dispensing range, achieving continuous production through intermittent suction. However, due to the intermittent stops of the suction pump, sometimes some of the adhesive drips from the ends of the conduits due to equipment vibration or gaps in the conduits. This dripping adhesive occurs in every two dispensing intervals, which typically involve compression and cutting, leading to problems such as inadequate sealing or side contamination on the subsequent packaging. Utility Model Content

[0005] The purpose of this invention is to provide a hydrogel dressing packaging machine to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydrogel dressing packaging machine, including a dispensing machine, and an upper mounting block and a lower mounting block that are interconnected. The inner wall of the upper mounting block is provided with an inner notch. A storage spring is provided between a movable block that is slidably disposed in the lower mounting block and the lower mounting block. A guide channel communicating with the dispensing machine is provided on the movable block, and the port of the guide channel faces the inner wall of the groove opened on the top of the lower mounting block.

[0007] Preferably, the inner wall of the chute is fixedly connected to a bottom pipe, and multiple mounting rods threaded on the movable block are slidably mounted on the lower mounting block. The energy storage spring is fixedly mounted between the lower mounting block and the support portion at the end of the mounting rod.

[0008] Preferably, the device includes a glue guide tube that is fixedly connected to the glue dispensing machine, and an outwardly turned part at the end of the glue guide tube is movably disposed at the bottom end of the bottom tube, and a metal sleeve threaded on the outer wall of the glue guide tube is rotatably disposed on the outer wall of the bottom tube.

[0009] Preferably, a sealing plate is fixedly installed on the top of the movable block, and an insert tube communicating with multiple adhesive channels is fixedly installed on the movable block, with the insert tube inserted into the bottom tube.

[0010] Preferably, a sealing rubber ring is fixedly installed on the outer wall of the cannula.

[0011] Preferably, the device includes a rubber tray movably mounted on the top of the upper mounting block, and multiple liquid guide tubes are fixedly connected to the rubber tray, with a support plate sleeved on the outer wall of the multiple liquid guide tubes.

[0012] Preferably, the upper mounting block has symmetrically hinged clamping flaps on the support platform.

[0013] Preferably, the curved surface of the clamping flap is movably mounted on the support plate.

[0014] Preferably, a sealing rubber gasket is provided at the bottom end of the bottom tube and the top end of the guide tube.

[0015] Preferably, the flange on the metal sleeve is located on the moving path of the support.

[0016] In the above technical solution, the hydrogel dressing packaging machine provided by this utility model has the following beneficial effects: when the dispensing machine starts dispensing, the hydrogel liquid is pumped into multiple guide channels on the movable block. At this time, because the port of the guide channel is closed by the inner wall of the chute, the hydraulic pressure in the guide channel increases, causing the movable block to slide, thereby moving the guide channel to the side of the inner groove for drainage. At the same time, the sliding of the movable block causes the storage spring to store force. Then, when the pumping stops, the storage spring releases the stored force and drives the movable block to move down. At this time, the downward movement of the movable block causes a piston state to be formed in the chute to achieve a certain suction effect, thereby solving the common problem of easy dripping from the end of the guide tube.

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-6 As shown, a hydrogel dressing packaging machine includes a dispensing machine, and also includes an upper mounting block 3 and a lower mounting block 1 that are interconnected. The inner wall of the upper mounting block 3 is provided with an inner notch 31. A storage spring 72 is provided between the movable block 2 that is slidably disposed inside the lower mounting block 1 and the lower mounting block 1. The movable block 2 is provided with a guide channel 23 that is connected to the dispensing machine, and the port of the guide channel 23 faces the inner wall of the slide groove 11 opened at the top of the lower mounting block 1. When the dispensing machine starts dispensing, the hydrogel liquid is pumped into multiple guide channels 23 on the movable block 2. At this time, because the port of the guide channel 23 is sealed by the inner wall of the slide groove 11, the hydraulic pressure in the guide channel 23 increases, causing the movable block 2 to slide. This causes the guide channel 23 to move to the side of the inner groove 31 for drainage. At the same time, the sliding of the movable block 2 causes the storage spring 72 to store force. Then, when the pumping stops, the storage spring 72 releases the stored force and drives the movable block 2 to move downward. During the downward movement of the movable block 2, a piston state is formed in the slide groove 11 to achieve a certain suction effect, thereby solving the common problem of easy dripping at the end of the guide tube.

[0022] Specifically, the dispensing machine in the above technical solution is a type of existing dispensing machine used for hydrogel packaging, which includes at least a suction pump for drawing out the adhesive liquid and a dispensing port; the lower mounting block 1 has a threaded hole, and the upper mounting block 3 has a through hole corresponding to the threaded hole. The lower mounting block 1 and the upper mounting block 3 are spliced ​​together, and then bolts are passed through the through hole and screwed onto the threaded hole to fix the lower mounting block 1 and the upper mounting block 3.

[0023] As a further technical solution provided by this utility model, the inner wall of the slide groove 11 is fixedly connected to the bottom tube 12, and multiple mounting rods 7 threaded on the movable block 2 are slidably disposed on the lower mounting block 1, and the storage spring 72 is fixedly installed between the lower mounting block 1 and the support portion 71 provided at the end of the mounting rod 7.

[0024] Specifically, the energy storage spring 72 is sleeved on the mounting rod 7. By allowing the mounting rod 7 to pass through the through hole on the lower mounting block 1 and rotate on the movable block 2, the mounting rod 7 can be quickly installed. The mounting rod 7 and the support 71 can also limit the sliding of the movable block 2. When the movable block 2 needs to be maintained in the future, the limitation on the movable block 2 can be released by disassembling the mounting rod 7.

[0025] Furthermore, it includes a glue guide tube 6 fixedly connected to the glue dispensing machine, and an outwardly turned part 61 provided at the end of the glue guide tube 6 is movably provided at the bottom end of the bottom tube 12, and a metal sleeve 63 fitted on the outer wall of the glue guide tube 6 is threaded and rotatably provided on the outer wall of the bottom tube 12.

[0026] Specifically, such as Figure 5As shown, by fixing the bottom end of the guide tube 6 to the dispensing port on the dispensing machine, and placing the top end of the guide tube 6 at the bottom end of the bottom tube 12, and then rotating the metal sleeve 63 on the outer wall of the bottom tube 12 through the thread, the guide tube 6 can be quickly installed and fixed, and it is also convenient to disassemble the guide tube 6 for maintenance.

[0027] Furthermore, a sealing plate 24 is fixedly installed on the top of the movable block 2, and an insertion tube 21 connected to multiple adhesive channels 23 is fixedly installed on the movable block 2, with the insertion tube 21 inserted into the bottom tube 12.

[0028] Specifically, the sealing plate 24 is bolted to the movable block 2 so that the adhesive guide channel 23 can be exposed for maintenance without disassembling the mounting rod 7. It moves through the insertion tube 21 inside the bottom tube 12. When the adhesive guide tube 6 is dispensing liquid, the adhesive enters the insertion tube 21 along the bottom tube 12 and simultaneously fills multiple adhesive guide channels 23. The adhesive guide channels 23 are sealed by the inner wall of the sliding groove 11. At this time, the increased hydraulic pressure in the bottom tube 12 and the insertion tube 21 will cause the insertion tube 21 to slide inside the bottom tube 12, thereby driving the movable block 2 to slide upward stably.

[0029] Furthermore, a sealing rubber ring 22 is fixedly installed on the outer wall of the insertion tube 21.

[0030] Specifically, the sealing performance between the bottom tube 12 and the insertion tube 21 is improved by using a sealing rubber ring 22.

[0031] Furthermore, it includes a rubber tray 5 movably mounted on the top of the upper mounting block 3, and multiple liquid guide tubes 51 are fixedly connected to the rubber tray 5, with a support plate 42 sleeved on the outer wall of the multiple liquid guide tubes 51.

[0032] Specifically, the rubber tray 5 is detachable, allowing it to be inserted into the top of the upper mounting block 3. The adhesive pumped into the upper mounting block 3 can be guided along the multiple liquid guide tubes 51 on the rubber tray 5 for dispensing. The support plate 42 can be fixedly installed on the top of the upper mounting block 3 to support, limit, and compress the rubber tray 5.

[0033] Furthermore, the support platform 32 on the upper mounting block 3 is symmetrically hinged with clamping flaps 4.

[0034] Specifically, the support plate 42 is secured by two clamping segments 4, facilitating quick fixation of the support plate 42 by a single bolt and nut. For subsequent disassembly, the support plate 42 and rubber tray 5 can be quickly removed for maintenance by unscrewing the bolt and nuts on the two clamping segments 4.

[0035] Furthermore, the curved surface 41 on the clamping petal 4 is movably mounted on the support plate 42.

[0036] Specifically, when the two clamping petals 4 clamp together, the curved surface 41 on the clamping petal 4 presses against the side of the support plate 42, thereby pressing the support plate 42 down onto the rubber tray 5. When the rubber tray 5 is used to achieve a seal, the pressure can also improve the sealing strength.

[0037] Furthermore, a sealing rubber gasket 62 is provided at the bottom end of the bottom tube 12 and the top end of the guide tube 6.

[0038] Specifically, the sealing rubber gasket 62 is used to further improve the sealing effect between the bottom end of the bottom tube 12 and the guide tube 6.

[0039] Furthermore, the flange 64 provided on the metal sleeve 63 is located on the moving path of the support 71.

[0040] Specifically, by utilizing the flanged portion 64 on the metal sleeve 63 to block the upward movement of the support portion 71, the guide channel 23 can be precisely positioned on one side of the inner groove 31 for stable glue discharge when the movable block 2 slides upward.

[0041] Working Principle: After the dispensing machine starts, the hydrogel liquid enters the insertion tube 21 on the movable block 2 through the dispensing tube 6 and the bottom tube 12, filling the dispensing channel 23. Initially, the outlet of the dispensing channel 23 is blocked by the inner wall of the slide groove 11, causing the hydraulic pressure in the pipeline to rise. This pressure pushes the insertion tube 21 to slide upward in the bottom tube 12, driving the entire movable block 2 to move upward against the elastic force of the storage spring 72, while the spring stores energy. When the movable block 2 moves to a specific position, the outlet of the dispensing channel 23 is aligned with the inner notch 31 on the side wall of the upper mounting block 3, and the glue is discharged through the inner notch 31, entering the rubber tray 5 above, and finally completing the filling of the dressing through the liquid guide tube 51 on it. When the dispensing machine stops pumping liquid, the hydraulic pressure in the pipeline disappears, the compressed storage spring 72 releases energy, and drives the movable block 2 to move downward back to its original position. The downward movement of the movable block 2 creates a piston-like negative pressure suction effect in the slide groove 11, which can draw back the residual glue at the port of the glue guide channel 23, thereby effectively preventing dripping after the glue pouring stops.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
