Description

Technical Field

[0001] The utility model relates to the technical field of plaster patch processing, in particular to a coating machine for plaster patch processing. Background Art

[0002] In the pharmaceutical and healthcare product manufacturing sector, plasters are a traditional and widely used treatment and healthcare method. The quality of their application during the manufacturing process is directly related to the product's ultimate efficacy and user experience. Traditional plaster application methods often rely on manual labor, which is not only inefficient but also difficult to ensure uniform and consistent application, increasing production costs and making quality control more difficult.

[0003] With the development of automation technology, automated plaster applicators have gradually emerged on the market, such as the plaster applicator disclosed in CN221490765U. This device uses a mechanical structure to automatically add, stir, and initially apply the ointment, significantly improving production efficiency. In particular, its unique stirring mechanism, which combines the up-and-down reciprocating sliding and rotation of the stirring shaft, effectively promotes uniform mixing of the ointment, avoids the problem of ointment coagulation, and lays a good foundation for subsequent application of the plaster.

[0004] However, despite significant improvements in mixing efficiency, these automated applicators still face significant deficiencies in monitoring and testing application quality. Current plaster applicators generally lack real-time monitoring capabilities for application status, making it impossible to immediately identify and reject unevenly applied patches. This results in unqualified products being rolled up during the production process even when there are issues with application quality, ultimately impacting the overall quality and market reputation of the entire batch of plasters.

[0005] Therefore, it is particularly important to develop a plaster applicator that can integrate the application quality detection function. Utility Model Content

[0006] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a plaster application machine for processing to solve the above problems.

[0007] To achieve the above-mentioned purpose, the utility model provides a plaster patch processing applicator, comprising a applicator body, wherein the applicator body is provided with a smearing mechanism, a cloth pressing mechanism and a smearing detection mechanism in sequence from left to right, the smearing mechanism being arranged on the applicator body for smearing the plaster onto the surface of a substrate, the cloth pressing mechanism being used to press a sticky transparent film onto the surface of the substrate to form a plaster patch, and the smearing detection mechanism being used to detect the smearing condition of the plaster patch, wherein a first cutting mechanism is provided between the smearing mechanism and the smearing detection mechanism, the applicator body is provided with a second cutting mechanism on the right side of the smearing detection mechanism, the first cutting mechanism and the second cutting mechanism are used to cut the plaster patch, and the cut plaster patch forms a left separation section and a right separation section on the left and right sides of the applicator body respectively, the applicator body is provided with a traction mechanism for traction the left separation section to the right separation section position, and the applicator body is provided with a heat sealing mechanism on the right side of the second cutting mechanism;

[0008] The traction mechanism includes traction blocks symmetrically slidably arranged on both sides of the applicator body, an upper clamping plate fixedly mounted on the traction blocks for clamping the plaster patch from the top, a lower clamping plate vertically movably mounted on the traction blocks for clamping the plaster patch from the bottom, and a driving mechanism arranged on the traction blocks for driving the lower clamping plate to move upward;

[0009] The smear detection mechanism includes a fixing frame fixed to the smear machine body, an industrial camera fixed on the fixing frame, and a control processor connected to the industrial camera.

[0010] Preferably, the cloth pressing mechanism includes a cloth pressing roller rotatably mounted on the applicator body, a sticky transparent film unwinding roller, and a motor fixed on the applicator body for driving the cloth pressing roller to rotate.

[0011] Preferably, an alarm is installed on the fixing frame, and the alarm is connected to the control processor.

[0012] Preferably, the heat sealing mechanism includes an electric cylinder fixed to the upper end of the applicator body, an upper heat sealing plate fixed to the lower end of the electric cylinder, and a lower heat sealing plate fixed to the surface of the applicator body.

[0015] Preferably, the coating mechanism includes a plaster jar fixed on the coating machine body, a discharge pipe arranged at the lower end of the plaster jar, and a discharge valve installed on the discharge pipe.

[0016] Compared with the existing technology, the present invention has the following benefits: the present invention is a coating machine for processing plasters equipped with an advanced coating detection mechanism, which uses an industrial camera to capture the surface image of the plaster and performs intelligent analysis through a control processor, which can promptly detect and identify quality problems such as uneven coating and missing plasters. Once a quality problem is detected, the machine will automatically trigger the cutting mechanism to perform precise cutting, remove the problem area, and avoid the production of unqualified products. At the same time, in order to further improve the flexibility and continuity of the production line, this machine also innovatively designed a traction mechanism and a heat sealing mechanism. When the cutting is completed, the traction mechanism can quickly pull the cut left separation section to the right separation section position, and heat-seal it through the heat sealing mechanism, thereby achieving rapid repair and overall restoration of the plaster. This design not only reduces the scrap rate, but also significantly improves the continuous operation capacity and production efficiency of the production line. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 The specific implementation methods of the present utility model are further described in detail.

[0024] like Figure 1-4 As shown, the utility model is a plaster patch processing applicator, including a plaster patch body 10, which is provided with a smearing mechanism 20, a cloth pressing mechanism 30 and a smearing detection mechanism 40 from left to right. The smearing mechanism 20 is provided on the applicator body 10 for smearing the plaster on the surface of the substrate a, the cloth pressing mechanism 30 is used to press the sticky transparent film b onto the surface of the substrate a to form a plaster patch c, and the sticky transparent film b is the smearing detection mechanism 40 for detecting the smearing condition of the plaster patch c.

[0025] A first cutting mechanism 50 is provided between the smearing mechanism 20 and the smearing detection mechanism 40, and a second cutting mechanism 60 is provided on the right side of the smearing detection mechanism 40 on the smearing machine body 10. The first cutting mechanism 50 and the second cutting mechanism 60 are both driven by the telescopic cylinder to cut the cutting knife, which will not be described in detail here. The first cutting mechanism 50 and the second cutting mechanism 60 are used to cut the unqualified areas of the plaster c. When the substrate a passes through the smearing mechanism 20, the ointment is applied to the surface of the substrate a by the smearing mechanism 20. Then, when the substrate a reaches the pressing mechanism 30, the adhesive transparent film b is pressed onto the surface of the substrate a by the pressing mechanism 30 to form a plaster. It should be noted that the plaster here has not been sliced ​​yet. The specific slicing work will be carried out in subsequent processing. Then, when the plaster c reaches the smearing detection mechanism 40, the smearing detection mechanism 40 detects the smearing condition of the plaster. When there is a quality problem with the smearing, the first cutting mechanism 50 and the second cutting mechanism 60 are used to cut the part, thereby ensuring the quality of the entire plaster.

[0026] Furthermore, the cut plaster patch c forms a left separation segment c1 and a right separation segment c2 on the left and right sides of the applicator body 10 respectively. The applicator body 10 is provided with a traction mechanism 70 for pulling the left separation segment c1 to the position of the right separation segment c2. The applicator body 10 is provided with a heat sealing mechanism 80 on the right side of the second cutting mechanism 60. After cutting off a section with poor coating quality, the staff inspects and debugs the machine. After troubleshooting, the traction mechanism 70 is used to pull the left separation segment c1 of the plaster patch c to move. During the traction process of the left separation segment c1 of the plaster patch c, the coating and pressing processes on its left side proceed as usual. After the left separation segment c1 is pulled to dock with the right separation segment c2, the left separation segment c1 and the right separation segment c2 are heat-sealed by the heat sealing mechanism 80, so that the left separation segment c1 and the right separation segment c2 cut into two sections can be reconnected into a whole, and the traction mechanism 70 returns to its original position.

[0027] The following is a specific embodiment of the traction mechanism 70:

[0028] Please refer to Figure 4The traction mechanism 70 includes traction blocks 71 symmetrically slidably arranged on both sides of the applicator body 10, an upper clamping plate 73 fixedly mounted on the traction block 71 for clamping the plaster patch c from the top, a lower clamping plate 72 vertically movably mounted on the traction block 71 for clamping the plaster patch c from the bottom, and a driving mechanism 74 arranged on the traction block 71 for driving the lower clamping plate 72 to move upward. It can be understood that the lower clamping plate 72 is arranged at the bottom of the plaster patch c. After the plaster patch c is cut, the driving mechanism 74 drives the lower clamping plate 72 to move upward and clamp the left separation segment c1 of the plaster patch c. Then the traction block 71 drags the left separation segment c1 to continue to move to the right and approach the right separation segment c2. Since the lower clamping plate 72 clamps the left separation segment c1 after moving upward, the end of the left separation segment c1 will be slightly higher than the right separation segment c2. In this way, when the left separation segment c1 is docked with the right separation segment c2, the end of the left separation segment c1 will move above the right separation segment c2.

[0029] Please refer to Figure 2 The smear detection mechanism 40 includes a fixing frame 41 fixed to the smear machine body 10, an industrial camera 42 fixed on the fixing frame 41, and a control processor 43 connected to the industrial camera 42. It can be understood that the industrial camera 42 can capture the shape of the plaster after smearing. When the smearing is uneven due to lack of plaster or other reasons, the image captured by the industrial camera 42 can be recognized by the control processor 43.

[0030] Furthermore, an alarm 44 is installed on the fixed frame 41, and the alarm 44 is connected to the control processor 43. When the industrial camera 42 captures an unqualified plaster patch c, the image data will be sent to the control processor 43. The control processor 43 will control the alarm 44 to sound an alarm after receiving the signal, reminding the staff to arrive at the scene. During this process, the entire machine can be suspended. After the staff arrives, the first cutting mechanism 50 and the second cutting mechanism 60 are controlled by the control processor 43 to cut off the unqualified area of ​​the plaster patch c, and then the cut plaster patch c is manually cleaned up. Then the control processor 43 can control the traction mechanism 70 to perform traction work.

[0031] In some embodiments, the cloth pressing mechanism 30 includes a cloth pressing roller 31 rotatably mounted on the applicator body 10, a sticky transparent film unwinding roller 32, and a motor 33 fixed on the applicator body 10 for driving the cloth pressing roller 31 to rotate. It can be understood that a winding device (not shown in the figure) is provided at the right end of the applicator body 10. The winding device can simultaneously wind up the substrate a and the sticky transparent film b (that is, the pressed plaster c). During the coating process, the motor 33 drives the cloth pressing roller 31 to rotate, thereby pressing the sticky transparent film b onto the surface of the substrate a and covering the plaster.

[0032] In some embodiments, the heat sealing mechanism 80 includes an electric cylinder 81 fixed to the upper end of the applicator body 10, an upper heat sealing plate 82 fixed to the lower end of the electric cylinder 81, and a lower heat sealing plate 83 fixed to the surface of the applicator body 10. When the left separation section c1 and the right separation section c2 are docked, the lower heat sealing plate 83 is located at the bottom side, and above it are the right separation section c2, the left separation section c1 and the upper heat sealing plate 82. The upper heat sealing plate 82 is driven downward by the electric cylinder 81, and the upper heat sealing plate 82 and the lower heat sealing plate 83 are heated by electric heating, so that the left separation section c1 and the right separation section c2 are thermally connected together.

[0033] Specifically, a moving mechanism 90 for driving the traction block 71 to slide is installed on the coating machine body 10.

[0034] In some embodiments, the moving mechanism 90 is a motor-screw mechanism connected to the control processor 43 .

[0035] In some embodiments, the coating mechanism 20 includes a plaster pot 21 fixed to the coating machine body 10 , a discharge pipe 22 disposed at the lower end of the plaster pot 21 , and a discharge valve 23 installed on the discharge pipe 22 .

[0036] The utility model is a plaster application machine, the specific working principle of which is as follows:

[0037] Substrate a passes beneath the applicator 20. The plaster jar 21 within the applicator 20 controls the flow of the plaster through the discharge pipe 22 and discharge valve 23, evenly applying an appropriate amount of plaster to the surface of substrate a. The plastered substrate a then moves rightward until it reaches the pressing mechanism 30. Driven by a motor 33, the pressing roller 31 within the pressing mechanism 30 rotates, pressing the adhesive transparent film b onto the plaster on substrate a, forming a preliminary plaster patch c. Plaster patch c then moves rightward to the application detection mechanism 40. An industrial camera 42 within this mechanism captures plaster patch c, transmitting the image data to the control processor 43 for analysis. If quality issues such as uneven application or missing plaster are detected, the control processor 43 controls the alarm 44 to sound an alarm and instructs the cutting mechanism to proceed. If a quality issue is detected, the first cutting mechanism 50 and the second cutting mechanism 60, respectively, cut the plaster patch c at locations before and after the application detection mechanism 40, removing the problematic area to form a left separated section c1 and a right separated section c2. After cutting, the traction mechanism 70 starts to work. Driven by the driving mechanism 74, its lower splint 72 moves upward and clamps the left separation segment c1, and then the traction block 71 drags the left separation segment c1 to the right to dock with the right separation segment c2. Due to the clamping method of the lower splint 72, the end of the left separation segment c1 will be slightly higher than the right separation segment c2, which is convenient for docking. Then, the heat sealing mechanism 80 starts to work. The electric cylinder 81 drives the upper heat sealing plate 82 to move downward, and together with the lower heat sealing plate 83, the left separation segment c1 and the right separation segment c2 are thermally connected together through electric heating, thereby restoring the integrity of the plaster patch c. After the repair is completed, the traction mechanism 70 returns to its original position, and the plaster patch c continues to move to the right for subsequent processing or winding.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
