Description

Technical Field

[0001] This invention relates to the field of plaster cutting and punching, and more particularly to a plaster cutting and punching device and method. Background Technology

[0002] Plaster cutting and punching refers to a comprehensive plaster processing technology that combines cutting and punching processes.

[0003] Traditionally, cutting and punching are two separate processing items with no interaction between them. As a result, manufacturers often need to purchase these two separate pieces of equipment to carry out the corresponding production work in the subsequent processing of plasters. However, with the gradual development of integrated and sophisticated design language, the desire to combine the two processing techniques has become increasingly prominent.

[0004] Currently, there are integrated processing devices that combine the above functions. However, based on practical considerations, the integrated design does not take into account the inherent characteristics of the plaster itself. For example, when cutting the plaster, the point of contact between the cutter and the plaster remains constant. As a result, the temperature at the contact point between the cutter and the plaster will rise significantly with processing time. This temperature increase will inevitably affect the morphology or properties of the adhesive and the adhesive tape in the plaster. Specifically, the adhesive tape softens when heated, increasing the difficulty of cutting. Secondly, the active pharmaceutical ingredients may volatilize when the adhesive is heated. Furthermore, the unchanging contact point between the cutter and the plaster will eventually change the sharpness of the cutting edge at that point, further affecting cutting efficiency.

[0005] Therefore, based on the aforementioned limitations, there is a need for a cutting and punching device that integrates cutting and punching design to improve cutting quality. Summary of the Invention

[0006] The purpose of this invention is to provide a device and method for cutting and punching plaster patches to solve the above-mentioned technical problems.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a plaster cutting and punching device, comprising a driving component and a transmission component. The driving component is a driving structure that drives the transmission component to rotate alternately in the forward or reverse direction. The driving component and the transmission component are arranged opposite to each other on a support frame. The transmission component includes a main shaft that is drivenly connected to the driving component and several sleeve wheels that are slidably mounted on the main shaft. Each of the sleeve wheels is rotatably adapted with a cutting blade that corresponds to one of the sleeve wheels. The cutting blade changes its cutting position with the plaster during the alternating forward or reverse rotation of the sleeve wheels.

[0008] Preferably, a support plate is installed at the support frame, and a cutting blade maintenance component is provided at one end of the support plate near the cutting blade. The cutting blade maintenance component includes a support box connected to the support plate and two maintenance components distributed above and below the support plate. The two maintenance components are rotatably installed at the support box.

[0009] The cutting blade intersects with and abuts against the two vertically distributed protective parts, which is used to rub the cutting edge of the cutting blade when the cutting blade changes its cutting position with the plaster.

[0010] Preferably, the sleeve wheel is further provided with a punching assembly, which includes a plurality of support rods corresponding one-to-one with the plurality of sleeve wheels and a punching rod. The plurality of support rods are fixedly connected to the plurality of sleeve wheels, and the plurality of support rods are installed at the punching rod. The punching rod is used to intermittently punch the plaster during the alternating forward or reverse rotation of the sleeve wheel.

[0011] Preferably, the side of the support rod that contacts the plaster has several conical puncture points.

[0012] Preferably, the drive assembly is equipped with a flow booster assembly connected to the cutting blade maintenance assembly pipeline. The flow booster assembly is linked to the main shaft and is used to generate airflow in the flow booster assembly when the main shaft rotates alternately in the forward or reverse direction.

[0013] Preferably, the flow booster includes an airflow generator connected to the main shaft and a branch pipe connected to the airflow generator pipe. The airflow generator is installed at the drive assembly. The branch pipe includes a main pipe connected to the airflow generator and two branch pipes connected to the main pipe. One end of each of the two branch pipes is equipped with a connecting pipe, which is connected to the support box for blowing airflow into the maintenance component.

[0014] Preferably, the airflow generator includes a housing and an outlet opened on the top of the housing. The outlet is connected to a split pipe. The housing is installed at the drive assembly, and a blade assembly connected to the main shaft is provided inside the housing. The blade assembly consists of multiple blades and is used to generate airflow into the housing during the alternating forward or reverse rotation of the main shaft.

[0015] Preferably, the junction between the maintenance component and the support box is provided with a conduit for receiving the maintenance component and the support box.

[0016] Preferably, the maintenance component includes a U-shaped blade holder and a through hole for insertion into the guide tube at the U-shaped blade holder. The U-shaped blade holder is a U-shaped frame with an internal cavity. A grinding plate is provided at the end of the U-shaped blade holder that contacts the cutting blade. The grinding plate is a porous grinding body. The grinding body is installed at the U-shaped blade holder, and the grinding plate communicates with the inner cavity of the U-shaped blade holder for airflow from the U-shaped blade holder to the grinding plate.

[0017] A method for cutting and punching holes in a plaster cutting and punching device, comprising the following steps:

[0018] 1) The main shaft is driven by the drive assembly to rotate alternately in the forward or reverse direction at the support frame, so that several wheels slidingly installed at the main shaft distribute the rotational force to the corresponding cutting blade, causing the cutting blade to perform a reciprocating cutting action on the adhesive plaster that is moving in the cutting direction of the cutting blade under the support of the cutting blade maintenance assembly.

[0019] 2) By installing a number of support rods equal to the number of the sleeve wheels at the sleeve wheels, when several support rods are installed at the same puncture rod, the sleeve wheels can puncture and punch the plaster that has traveled to the tray plate while rotating in the forward or reverse direction.

[0020] The beneficial effects of this invention are:

[0021] 1. The drive assembly drives the main shaft to rotate alternately in the forward and reverse directions at the support frame. This causes several wheels slidingly mounted on the main shaft to distribute the rotational force to the corresponding cutting blades. As a result, the cutting blades, supported by the cutting blade maintenance assembly, perform reciprocating cutting motions on the adhesive plaster that is moving in the cutting direction of the cutting blade, so as to meet the specific needs of continuously changing the cutting position of the adhesive plaster during the cutting process.

[0022] 2. By installing a number of support rods equal to the number of sleeve wheels at the sleeve wheel, when several support rods are installed at the same punching rod, the sleeve wheel rotates in the forward or reverse direction to punch the plaster that has traveled to the tray. That is, punching and punching are done first, and cutting is done later. Moreover, punching and punching and cutting share the same driving energy, thereby simplifying the processing process and improving the efficiency of kinetic energy utilization.

[0032] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0033] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0034] Example 1

[0035] This embodiment proposes a plaster cutting and punching device, including a drive assembly 2 and a transmission assembly 5. The drive assembly 2 is a drive structure that drives the transmission assembly 5 to rotate alternately in the forward or reverse direction. The drive assembly 2 and the transmission assembly 5 are arranged opposite to each other between the support frame 1. The transmission assembly 5 includes a main shaft 51 that is connected to the drive assembly 2 and a plurality of sleeve wheels 52 that are slidably mounted on the main shaft 51. Each of the sleeve wheels 52 is rotatably adapted to a cutting blade 7 that corresponds to one of the sleeve wheels 52. The cutting blade 7 changes its cutting position with the plaster during the alternating forward or reverse rotation of the sleeve wheels 52.

[0036] Please refer to Figure 1-8 The drive assembly 2 drives the main shaft 51 to rotate alternately in the forward and reverse directions at the support frame 1. This causes several sleeves 52, which are slidably mounted on the main shaft 51, to distribute the rotational force to the corresponding cutting blades 7. This causes the cutting blades 7, supported by the cutting blade maintenance assembly 8, to perform reciprocating cutting motions on the adhesive tape that is moving in the cutting direction of the cutting blades 7. This is to meet the specific requirement of constantly changing the cutting position of the adhesive tape during cutting, that is, to avoid the cutting blades 7 from always being in contact with the adhesive tape at one point, which would cause the surface temperature of the cutting blades 7 to rise and have a negative impact on the adhesive and the adhesive tape.

[0037] In addition, to further optimize the adjustable properties of the cutting, several sets of wheels 52 are slidably mounted on the main shaft 51 so that the required cutting size can be adapted as the several sets of wheels 52 slide relative to the main shaft 51.

[0038] Of course, the cutting blade 7 integrates multiple functions in changing the cutting position of the plaster, including the polishing function, simultaneous cutting and punching, and cooling function. The following are detailed descriptions of these functions through several specific implementation processes:

[0039] In specific implementation, a support plate 6 is installed at the support frame 1. A cutter maintenance component 8 is provided at one end of the support plate 6 that is close to the cutter 7. The cutter maintenance component 8 includes a support box 81 connected to the support plate 6 and two maintenance components 82 distributed vertically above and below the support plate 6. The two maintenance components 82 are rotatably installed at the support box 81.

[0040] In this process, the cutting blade 7 intersects with the two protective parts 82 distributed vertically, and abuts against the two protective parts 82 distributed vertically, so as to rub the cutting edge of the cutting blade 7 when the cutting blade 7 changes the cutting position with the plaster.

[0041] like Figure 1-5 As shown, the cutting blade 7 is supported by the cutting blade maintenance component 8 during the reciprocating motion. Based on this, the grinding structure set at the maintenance component 82 performs a reciprocating grinding action during the reciprocating motion of the cutting blade 7 to ensure the sharpness of the cutting blade 7 and further improve the smoothness of cutting.

[0042] In addition, by Figure 5 As shown, the maintenance component 82 is rotatably mounted on the support box 81. It can be seen that, in order to adapt to the constantly changing relative position of the cutting blade 7, the maintenance component 82 is rotatably mounted on the support box 81, which can provide all-round support function during the movement of the cutting blade 7.

[0043] In specific implementation, the sleeve wheel 52 is also provided with a punching component 4. The punching component 4 includes a number of support rods 42 corresponding to a number of sleeve wheels 52 and a punching rod 41. The number of support rods 42 are fixedly connected to a number of sleeve wheels 52, and the number of support rods 42 are installed at the punching rod 41. The punching rod 41 is used to intermittently punch the plaster when the sleeve wheel 52 rotates in the forward or reverse direction. More specifically, the side of the support rod 42 that contacts the plaster is provided with a number of conical punching parts.

[0044] like Figure 1-4As shown, the combination of cutting and punching is a processing technology that is urgently needed at present. To address this, by installing a number of support rods 42 at the sleeve wheel 52 in proportion to the number of sleeve wheel 52, when several support rods 42 are installed at the same punching rod 41, the sleeve wheel 52 performs punching on the plaster that has traveled to the tray 6 while rotating in the forward or reverse direction. That is, punching and punching are done first, and cutting is done later. Moreover, punching and punching and cutting share the same driving energy, thereby simplifying the processing process and improving the efficiency of kinetic energy utilization.

[0045] In addition, the position of the support rod 42 can be adjusted along with the sleeve wheel 52. After the position is adjusted, the installation process from the support rod 42 to the stick 41 is repeated to install and fix the support rod 42.

[0046] In specific implementation, a flow booster 3 is installed at the drive assembly 2 and connected to the cutting blade maintenance assembly 8 via a pipe. The flow booster 3 is linked with the main shaft 51 and is used to generate airflow in the flow booster 3 when the main shaft 51 rotates alternately in the forward or reverse direction. The flow booster 3 includes an airflow generator 31 connected to the main shaft 51 and a branch pipe 32 connected to the airflow generator 31 via a pipe. The airflow generator 31 is installed at the drive assembly 2. The branch pipe 32 includes a main pipe connected to the airflow generator 31 and two branch pipes connected to the main pipe. One end of each of the two branch pipes is equipped with a connecting pipe 33. The connecting pipe 33 is connected to the support box 81 and is used to blow airflow into the maintenance component 82.

[0047] The airflow generation mechanism is that the airflow generator 31 includes a housing 313 and an outlet 312 opened on the top of the housing 313. The outlet 312 is connected to the split pipe 32. The housing 313 is installed at the drive assembly 2, and the housing 313 is provided with a blade group 311 connected to the main shaft 51. The blade group 311 is composed of multiple blades and is used to generate airflow in the housing 313 during the alternating forward or reverse rotation of the main shaft 51.

[0048] like Figure 1 , 2 As shown in Figures 7 and 8, the kinetic energy of the main shaft 51 not only acts on the cutting blade 7 and the punching assembly 4, but also distributes the kinetic energy to the blade assembly 311 during forward or reverse rotation, so as to generate suction or exhaust airflow in the pipe combined with the split pipe 32 and the connecting pipe 33 during the alternating forward and reverse rotation of the blade assembly 311 to the housing 313.

[0049] In specific implementation, the junction between the maintenance component 82 and the support box 81 is provided with a conduit for receiving the maintenance component 82 and the support box 81. The maintenance component 82 includes a U-shaped knife holder 822 and a through hole 821 opened at the U-shaped knife holder 822 for receiving the conduit. The U-shaped knife holder 822 is a U-shaped frame with an internal cavity. The end of the U-shaped knife holder 822 that contacts the cutting blade 7 is provided with a grinding plate 823. The grinding plate 823 is a grinding body with pores. The grinding body is installed at the U-shaped knife holder 822, and the grinding plate 823 communicates with the inner cavity of the U-shaped knife holder 822 for airflow from the U-shaped knife holder 822 to the grinding plate 823.

[0050] like Figure 1-6 As shown, the suction or exhaust flow generated by the airflow generator 31 is injected into the U-shaped blade holder 822 through the guide tube. Based on this, a grinding plate 823 connected to the U-shaped blade holder 822 is installed at the U-shaped blade holder 822. During the reciprocating grinding process of the cutting blade 7 by the grinding plate 823, the heat generated by the cutting blade 7 during the grinding process is dissipated by the airflow change on the surface of the cutting blade 7, so as to ensure that the cutting blade 7 maintains a relatively stable temperature for cutting the plaster.

[0051] Depend on Figure 6 As can be seen from the two diagrams, when the airflow generator 31 generates airflow that is either discharged outward or drawn inward, the airflow always flows near the U-shaped blade holder 822. Based on this, it is feasible to use the flowing airflow to dissipate heat from the cutting blade 7.

[0052] As for how the airflow generator 31 generates the intake or exhaust airflow, the housing 313 is a relatively closed container, and the only channel for communication with the outside is the maintenance component 82. Therefore, when the main shaft 51 drives the blade assembly 311 to rotate, the airflow change can only be generated at the maintenance component 82.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
