[0002] Non-invasive skin staplers, as an important medical device, have significant advantages in wound closure and tension reduction. In the production process of non-invasive skin staplers, the preparation and coating of hydrocolloids are key steps, and the performance of their processes and equipment directly affects the quality and production efficiency of the stapler.

[0003] Traditional hydrocolloid preparation and coating processes have numerous problems. In traditional production processes, the preparation and coating of the hydrocolloid are two independent steps. Because there is a time interval between preparation and coating, and each step requires a certain amount of time to complete its respective operation, after preparation, the hydrocolloid needs to be transferred to a special storage container, cooled, and then transported to the coating equipment for heat treatment before the coating operation. Traditional hydrocolloid preparation and coating processes are not only time-consuming and costly, but also affect coating quality, consequently impacting the sealing performance and adhesion of the resulting anastomosis device. Utility Model Content

[0004] The technical problem solved by this embodiment of the invention is that the traditional adhesive coating process has a long production cycle, high time cost, and affects the coating quality.

[0005] To address the aforementioned technical problems, this utility model provides an adhesive tape preparation device, comprising: an adhesive preparation machine, including: a preparation environment providing module for providing a process environment for preparing hydrocolloids; a state holding module for providing preset pressure and temperature; a preparation furnace, switchably coupled to the preparation environment providing module or the state holding module, wherein, in the preparation state, the preparation furnace is coupled to the preparation environment providing module, and the hydrocolloid is prepared under the process environment provided by the preparation environment providing module; in the holding state, the preparation furnace is switched to be coupled to the state holding module, and the prepared hydrocolloid is held within a preset pressure and temperature range; and a coating machine, connected to the preparation furnace via a feed pipe, wherein, in the holding state, the hydrocolloid in the preparation furnace can be introduced through the feed pipe and coated onto a release film.

[0015] Compared with the prior art, the technical solution of this utility model embodiment has the following beneficial effects:

[0016] The tape preparation equipment provided by this utility model includes an adhesive preparation machine and a coating machine. Since the adhesive preparation machine includes a preparation environment providing module for providing the process environment for hydrocolloid preparation and a state maintenance module for providing preset pressure and temperature, in the preparation state, the preparation furnace is coupled to the preparation environment providing module, and the hydrocolloid is prepared under the process environment provided by the preparation environment providing module. After the hydrocolloid preparation is completed, in the holding state, the preparation furnace switches to the state maintenance module, maintaining the prepared hydrocolloid within the preset pressure and temperature range. In the holding state, the hydrocolloid in the preparation furnace is introduced to the coating machine through a conveying pipe and coated onto a release film. This integrates the adhesive preparation and coating processes. By maintaining the pressure and temperature of the hydrocolloid through the state maintenance module, the hydrocolloid can be kept in an optimal molten state, avoiding performance changes caused by repeated cooling and heating of the hydrocolloid, improving coating quality, shortening the production cycle, and reducing costs.

[0021] As mentioned above, traditional hydrocolloid preparation and coating processes have long production cycles, high time costs, and negatively impact coating quality. Specifically, in traditional production processes, hydrocolloid preparation and coating are two independent steps. After preparation, the hydrocolloid needs to be transferred to a specialized storage container, cooled, and then transported to the coating equipment for heat treatment before coating can begin. Because there is a time interval between preparation and coating, and each step requires time to complete, the entire production cycle is lengthy. For example, it may take several hours or even longer from the completion of hydrocolloid preparation to the start of coating, severely impacting production efficiency and failing to meet the demands of large-scale production. Furthermore, this separate production process involves multiple manual operations and equipment switching steps, making the entire process cumbersome and complex, increasing production time and labor costs.

[0022] In addition, repeated heating and cooling affect the properties of hydrocolloids, specifically in terms of changes in chemical properties and a decrease in physical properties.

[0023] Specifically, during the cooling process, the molecular structure and chemical bonds within hydrocolloids change, leading to alterations in their chemical properties. Certain chemical components may decompose or recombine, affecting key performance indicators such as viscosity and elasticity. Reheating may further exacerbate these changes, making the hydrocolloid's properties even more unstable.

[0024] Repeated cooling and heating can also negatively impact the physical properties of hydrocolloids. Specifically, during cooling, hydrocolloids may crystallize or precipitate, leading to decreased uniformity and stability. Upon reheating, these uneven areas may worsen, making it difficult for the hydrocolloid to distribute evenly during coating. This can result in localized accumulation or missed areas, leading to poor adhesion of the coated tape. When used in an anastomosis device, this will affect the device's sealing performance and adhesion.

[0025] To address the aforementioned problems, this application provides a tape preparation device comprising an adhesive preparation machine and a coating machine. The adhesive preparation machine includes a preparation environment providing module for providing the process environment for hydrocolloid preparation and a state maintenance module for providing preset pressure and temperature. In the preparation state, the preparation furnace is coupled to the preparation environment providing module, and the hydrocolloid is prepared under the process environment provided by the preparation environment providing module. After the hydrocolloid preparation is completed, in the maintenance state, the preparation furnace is switched to be coupled to the state maintenance module, maintaining the prepared hydrocolloid within the preset pressure and temperature range. In the maintenance state, the hydrocolloid in the preparation furnace is introduced to the coating machine through a conveying pipe and coated onto a release film. This integrates the adhesive preparation and coating processes. By maintaining the pressure and temperature of the hydrocolloid through the state maintenance module, the hydrocolloid can be kept in an optimal molten state, avoiding performance changes caused by repeated cooling and heating of the hydrocolloid, ensuring the performance stability of the hydrocolloid, improving coating quality, shortening the production cycle, and reducing costs.

[0026] To make the above-mentioned objectives, features and beneficial effects of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] This application provides an adhesive tape preparation apparatus that integrates adhesive preparation and coating. This apparatus can be used in the production process of surgical staplers, specifically in the preparation and coating steps of the hydrocolloid. The adhesive tape prepared by this apparatus can be used to manufacture surgical staplers. The following describes the process in conjunction with... Figures 1 to 4 The specific structure of the tape preparation equipment is described.

[0028] In specific implementation, the tape preparation equipment 100 includes: a glue-making machine 10 and a coating machine 20.

[0029] The hydrocolloid forming machine 10 includes a preparation environment providing module 11, a state holding module 12, and a preparation furnace 13. The preparation environment providing module 11 provides the process environment for hydrocolloid preparation. The state holding module 12 provides preset pressure and temperature. The preparation furnace 13 is switchably coupled to either the preparation environment providing module 11 or the state holding module 12. Specifically, in the preparation state, the preparation furnace 13 is coupled to the preparation environment providing module 11, and the hydrocolloid is prepared under the process environment provided by the preparation environment providing module 11; in the holding state, the preparation furnace 13 is switched to be coupled to the state holding module 12, maintaining the prepared hydrocolloid within a preset pressure and temperature range.

[0030] The coating machine 20 is connected to the preparation furnace 13 through the feed pipe 30. In the holding state, the hydrocolloid in the preparation furnace 13 can be introduced through the feed pipe 30 and coated onto the release film.

[0031] As can be seen from the above, the adhesive preparation machine 10 includes a preparation environment providing module 11 and a state holding module 12. In the preparation state, the preparation furnace 13 is coupled to the preparation environment providing module 11, and the hydrocolloid is prepared under the process environment provided by the preparation environment providing module 11. After the hydrocolloid is prepared, in the holding state, the preparation furnace 13 is switched to be coupled to the state holding module 12, and the prepared hydrocolloid is maintained within a preset pressure and temperature range. In the holding state, the hydrocolloid in the preparation furnace 13 is introduced to the coating machine 20 through the feed pipe 30 and coated onto the release film. Therefore, the tape preparation equipment 100 provided in this application can realize the integration of adhesive preparation and coating processes. By maintaining the pressure and temperature of the hydrocolloid through the state holding module 12, the hydrocolloid can be kept in a better molten state, avoiding repeated cooling and heating of the hydrocolloid, thereby effectively reducing the probability of changes in the chemical and physical properties of the hydrocolloid due to repeated heating and cooling, ensuring the performance stability of the hydrocolloid, and improving the coating quality. Furthermore, it integrates the adhesive preparation and coating processes, enabling effective connection between the two processes, simplifying production steps and procedures, achieving continuous production, avoiding production interruptions and waiting times caused by process separation in traditional processes, shortening the production cycle, reducing costs, improving production efficiency, and helping to meet the needs of large-scale production.

[0032] In some embodiments, the preparation environment providing module 11 may include a stirring assembly, a heating unit, and a pressure adjustment unit. The stirring assembly provides a stirring process environment. The heating unit provides a heating environment. The pressure adjustment unit provides a pressure environment.

[0033] The preparation environment providing module 11 may also include a sealing cover 112. The stirring assembly, heating unit, and pressure adjustment unit may be arranged on the sealing cover 112 or extend into the preparation furnace 13 through the sealing cover 112.

[0034] The sealing cap 112 is used to seal the preparation furnace 13. For example, the preparation furnace 13 has a feeding port through which materials for preparing hydrocolloids can be fed into the preparation furnace 13. The sealing cap 112 covers the feeding port of the preparation furnace 13 to achieve a seal on the preparation furnace 13.

[0035] The heating unit can heat the materials inside the preparation furnace 13, ensuring that the temperature inside the preparation furnace 13 is within the temperature range required for hydrocolloid preparation, thus providing the temperature conditions for the hydrocolloid to reach a molten state. The heating unit may include suitable heating elements with heating functions such as heating wires, heating plates, and heating tubes.

[0036] The pressure adjustment unit can adjust the pressure inside the preparation furnace 13. By adjusting the pressure inside the preparation furnace 13, the pressure inside the preparation furnace 13 can be kept within the pressure range required for the preparation of hydrocolloids, thus providing suitable pressure conditions for the preparation of hydrocolloids. The pressure adjustment unit can increase the pressure inside the preparation furnace 13, that is, increase the pressure inside the preparation furnace 13; the pressure adjustment unit can also decrease the pressure inside the preparation furnace 13, that is, decrease the pressure inside the preparation furnace 13.

[0037] The stirring assembly can stir the materials inside the preparation furnace 13. In some embodiments, the stirring assembly may include a first drive unit, a connecting shaft, and a stirring unit 111. The first drive unit is connected to the stirring unit 111 via the connecting shaft and is used to drive the stirring unit 111 to rotate, thereby stirring the materials inside the preparation furnace 13. The first drive unit may be a component with a driving function, such as a drive motor.

[0038] In a specific implementation, the state-maintaining module 12 includes a cover, a temperature adjustment unit, and a pressure adjustment unit. The cover is used to seal the feeding port of the preparation furnace 13 to maintain the preparation furnace 13 under sealed conditions, reducing the oxidation of the hydrocolloid by external air and allowing the hydrocolloid to maintain relatively optimal performance. The temperature adjustment unit is located on the cover and is used to provide a preset temperature to maintain the hydrocolloid in the preparation furnace 13 within a suitable temperature range, which helps to keep the hydrocolloid in a molten state; the pressure adjustment unit is located on the cover and is used to provide a preset pressure.

[0039] In some non-limiting embodiments, the state holding module 12 provides a preset pressure to the preparation furnace 13 that is greater than the pressure of the external environment. In this way, the hydrocolloid can be automatically introduced into the coating machine 20 under the pressure of the preset pressure, and the hydrocolloid can be introduced into the coating machine 20 from the preparation furnace 13 without the need for additional power equipment.

[0040] In some embodiments, the preparation furnace 13 may be provided with an outlet for connecting the feed pipe 30.

[0041] In some non-limiting embodiments, the outlet may be located on the side wall of the preparation furnace 13 and near the bottom.

[0042] Furthermore, the preparation furnace 13 also includes a switching element. In the preparation state, the switching element is configured to seal the outlet to ensure that the material, hydrocolloid semi-finished product, or prepared hydrocolloid remains within the preparation furnace 13 and does not leak from the outlet. In the holding state, the switching element is configured to open the outlet to ensure that the hydrocolloid can be smoothly introduced from the preparation furnace 13 into the coating machine 20. The switching element can be a switch, valve, etc.

[0043] In a specific implementation, the glue-making machine 10 further includes a sliding component. The sliding component includes a slide rail 141 and a slider. The slide rail 141 is disposed between the preparation environment providing module 11 and the state holding module 12, and extends along the direction from the preparation environment providing module 11 to the state holding module 12; the sliding part is disposed at the bottom of the preparation furnace 13, the sliding part is adapted to the slide rail 141, and can move along the slide rail 141.

[0044] In some embodiments, the sliding part can be a component such as a slider or pulley that can move in conjunction with the slide rail 141. The number of sliding parts can be one or more, depending on the specific structure of the sliding parts and the stability requirements of the preparation furnace 13.

[0045] In some non-limiting embodiments, there can be multiple slide rails 141, each connecting the preparation environment supply module 11 to the state holding module 12. This allows for the configuration of multiple preparation furnaces 13. Taking two preparation furnaces 13 as an example, one furnace 13 is coupled to the preparation environment supply module 11 and is in the preparation state, preparing the hydrocolloid. The other furnace 13 has completed the hydrocolloid preparation and is in the holding state, connected to the coating machine 20 via the feed pipe 30 to introduce the hydrocolloid into the coating machine 20 and coat it with a release film. This allows for the simultaneous preparation and coating of the hydrocolloid, further shortening the production cycle and improving production efficiency.

[0046] In some embodiments, there can be multiple state holding modules 12 and multiple preparation environment providing modules 11. The number of state holding modules 12 and the number of preparation environment providing modules 11 can be configured according to the preparation time of the hydrocolloid and the consumption of the hydrocolloid during coating, so that the preparation time and consumption of the hydrocolloid are matched, so as to further optimize the hydrocolloid preparation and coating process and improve production efficiency.

[0047] In a specific implementation, the glue-making machine 10 further includes a positioning part 15. The positioning part 15 is used to limit the movement position of the sliding part relative to the slide rail 141, so as to position the preparation furnace 13 to a position corresponding to the state holding module 12.

[0048] In some embodiments, the positioning part 15 may be a positioning plate with a slot, which engages with the sliding part. It is understood that the positioning part 15 may also be a baffle or the like.

[0049] In some embodiments, the tape preparation equipment further includes a lifting mechanism 16. The lifting mechanism 16 is connected to the state holding module 12 and is used to adjust the position of the state holding module 12 in the vertical direction.

[0050] In some non-limiting embodiments, the lifting mechanism 16 may include a column 161, a support portion 162, and a second drive portion. The column 161 supports the support portion 162. The support portion 162 carries the state holding module 12. The second drive portion drives the support portion 162 to move vertically along the column 161. The second drive portion may be a cylinder, motor, or other component with a driving function, and is not limited here.

[0051] In a specific implementation, the glue-making machine 10 further includes a stage 17. The stage 17 is used to support the environment preparation and provision module 11, the preparation furnace 13, and the state maintenance module 12.

[0052] In a specific implementation, the outlet of the conveying pipe 30 is provided with a material leveling section, which is used to uniformly output the hydrocolloid to the feed inlet of the coating machine. The material leveling section can be connected to the outlet of the conveying pipe 30 as an independent component, or it can be integrally formed into the outlet of the conveying pipe 30.

[0053] In some embodiments, the leveling section can be a flat nozzle. Along the width direction of the release film, the size of the flat nozzle is the same as or smaller than the width of the release film by a first dimension. The first dimension can be configured as needed; the smaller the first dimension, the better the uniformity of the hydrocolloid coating.

[0054] In some embodiments, the feed pipe 30 has an insulation layer. The insulation layer helps to keep the hydrocolloid conveyed in the feed pipe 30 warm, keeping the hydrocolloid in a molten state and ensuring the coating effect.

[0055] The insulation layer can be an integral part of the material conveying pipe 30, or it can be a specially designed insulation structure applied to the outside of the material conveying pipe 30 later. The insulation layer can be a component with heat insulation function, such as insulation cotton.

[0056] In some embodiments, the tape preparation equipment 100 further includes a cooling module 40. The cooling module 40 is disposed downstream of the coating machine 20 and is used to cool the release film coated with hydrocolloid. It should be noted that the cooling module 40 being disposed downstream of the coating machine 20 means that the cooling module 40 cools the hydrocolloid roll output from the coating machine 20; that is, the cooling process of the cooling module 40 is after the coating process of the coating machine 20.

[0057] In some embodiments, the cooling module 40 may include: a housing and a cooling section disposed within the housing. The cooling section can be used to maintain the temperature inside the housing 40 within a relatively low temperature range so that the release film coated with hydrocolloid (also known as hydrocolloid roll material) can be cooled quickly. By shortening the hydrocolloid cooling time, the hydrocolloid shrinkage and oxidation reaction caused by natural cooling can be reduced, thereby improving the performance of the resulting tape.

[0058] In some embodiments, the housing may have an opening for receiving a release film coated with hydrocolloid.

[0059] In some embodiments, the release film consists of two layers, namely an upper release film 201 and a lower release film 202, with the hydrocolloid located between the upper release film 201 and the lower release film 202.

[0060] The coating machine 20 includes: an upper release film conveyor belt 21 for conveying the upper release film 201, a lower release film conveyor belt 22 for conveying the lower release film 202, an upper roller 23, and a lower roller 24. The upper roller 23 and the lower roller 24 rotate in opposite directions to crush the upper release film 204, the lower release film 202, and the hydrocolloid between the upper roller 23 and the lower roller 24, and to prepare a hydrocolloid roll 200.

[0061] In practice, by precisely controlling the distance and pressure between the upper pressure roller 23 and the lower pressure roller 24, the hydrocolloid can be extruded and evenly applied between the two layers of release film to form a hydrocolloid roll 200. After cooling, the hydrocolloid roll 200 becomes an adhesive tape.

[0062] It should be noted that the coating machine 20 may also include a drive device for driving the upper pressure roller 23, the lower pressure roller 24, the upper release film conveyor belt 21, and the lower release film conveyor belt 22, and may also include a controller for controlling the drive device. For example, by controlling the drive device through the controller, the rotation of the upper pressure roller 23 and the lower pressure roller 24, as well as the spacing and pressure between them, can be controlled. Furthermore, by controlling the drive device through the controller, the upper release film conveyor belt 21 can be controlled to transport the upper release film 201, or the lower release film conveyor belt 22 can be controlled to transport the lower release film 202.

[0063] In addition, the coating uniformity can be further improved by controlling the roller precision of the selected coating machine 20, so as to ensure the quality and consistency of the obtained tape, which helps to improve the overall quality of the non-invasive skin stapler and reduce the defect rate.

[0064] In some embodiments, problems such as coating thickness deviation and changes in hydrocolloid flowability may occur during the production process. Operators may find it difficult to detect these problems in time and can only discover the quality issues through testing after production is completed. This not only increases the defect rate but also wastes a lot of time and resources.

[0065] To address the aforementioned problems, in this embodiment of the invention, the tape preparation equipment further includes a thickness detection device. The thickness detection device is located downstream of the coating machine and is used to detect the thickness of the tape. By detecting the thickness of the tape, abnormalities during the coating process can be identified promptly, facilitating timely adjustments, reducing the defect rate, and saving time and resources.

[0066] Furthermore, the thickness detection device is located downstream of the cooling module 40. It should be noted that "the thickness detection device is located downstream of the cooling module 40" means that the thickness detection process of the thickness detection device is performed after the cooling process of the cooling module 40, and the thickness detection device performs thickness detection on the tape obtained from the cooling module 40.

[0067] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
