Description

Technical Field

[0001] This utility model relates to the field of adhesive application, and more particularly to a movable adhesive application module. Background Technology

[0002] In order to avoid cross-infection and maintain a sterile area in hospital beds, operating rooms and physiotherapy rooms, disposable sheets are usually laid on the corresponding nursing beds. In addition, to concentrate the doctor's attention, surgical drapes are used to cover all parts of the patient except the surgical incision. In order to prevent the non-woven fabric main sheets (hereinafter referred to as main sheets) from shifting during use, double-sided tape is usually applied manually to fix the corresponding products in place. However, manual application is prone to contamination. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a movable adhesive application module for applying adhesive to the main body of nonwoven fabrics.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a movable adhesive applicator module, characterized in that it includes a translation bracket, an unwinding shaft, a traction roller group, a suction conveying assembly, and a cutting assembly. The unwinding shaft, traction roller group, suction conveying assembly, and cutting assembly are all mounted on the translation bracket, which can move left and right relative to the frame. The unwinding shaft is rotatably located at the end of the translation bracket. The traction roller group is located downstream of the unwinding shaft. The suction conveying assembly is located downstream of the traction roller group, and includes a first conveying surface and a second conveying arc surface. Both the first and second conveying arc surfaces have a plurality of suction holes. The discharge end of the first conveying surface is connected to the inlet end of the second conveying arc surface, and the discharge end of the second conveying arc surface is connected to a conveying platform for conveying the material to be applied. The cutting assembly includes a cutter for cutting the rolled material at the second conveying arc surface.

[0005] This invention integrates the unwinding shaft, traction roller group, suction conveying assembly, and cutting assembly on a translational support to form a movable adhesive application module, adapting to different adhesive application needs. The first conveying surface and the traction assembly work together to ensure the tension of the roll material, while the second conveying arc surface transfers the roll material to the conveying platform, enabling the roll material to be applied to the master sheet. In addition, the cutting assembly is used to cut the roll material into appropriate lengths, completing the automatic adhesive application of the master sheet, improving production efficiency, and avoiding contamination of the master sheet.

[0006] Preferably, the first conveying surface is disposed on the adsorption conveyor belt, and the first conveying surface is configured to be horizontal or inclined from top to bottom.

[0007] Furthermore, the conveying speed of the first conveying surface is configured to be greater than the conveying speed of the traction roller group. A conveying speed of the first conveying surface that is appropriately greater than the conveying speed of the traction roller group can straighten the coiled material and maintain a certain tension.

[0008] Preferably, the second conveying arc surface is disposed on the suction roller, which has a feeding station, a compounding station, and a non-working station. The suction roller includes a fixed base and a rotating base. The fixed base is fixedly disposed on a translational support, and the feeding station, compounding station, and non-working station are rotatably connected through the rotating base. The fixed base includes a suction area and a windless area. The suction area has a groove communicating with a negative pressure source. The adsorption holes at the feeding station and the compounding station communicate with the groove in the suction area, and the adsorption holes at the non-working station are located in the windless area. The suction area provides adsorption force to fix the roll material to the surface of the suction roller, while the windless area has no adsorption force, preventing the roll material from being carried away and ensuring that the roll material is stably adhered to the master sheet.

[0009] Preferably, the conveying platform is positioned below the second conveying arc surface, and the conveying speed of the conveying platform is equal to the conveying speed of the second conveying arc surface. The roll material is attached to the upper surface of the main guide for easy observation by the operator for equipment debugging.

[0010] Preferably, the translation support moves horizontally relative to the frame via a guide assembly; the guide assembly includes linear bearings and a guide shaft, the linear bearings are fixedly mounted on the left and right sides of the translation support, the guide shaft is fixedly mounted on the frame, and the linear bearings are sleeved on the guide shaft. The linear bearings and the guide shaft cooperate to achieve stable movement of the translation support.

[0011] Preferably, the cutter has a rotary cutting power source that drives its rotation, and the rotary cutting power source drives the cutter to cooperate with the cutting area on the rotating base to achieve material cutting. The cutter has an independent rotary cutting power source, which can adapt to cutting rolls of different lengths and to different adhesive application layouts.

[0012] Preferably, the traction roller assembly includes an upper roller and a lower roller. The upper roller is rotatably mounted on a lifting base, and the lower roller is connected to a rotary power source that drives its rotation. The upper roller is mounted on the lifting base to allow for vertical movement, facilitating the entry of the rolled material.

[0013] Preferably, a scraping unit is provided between the traction roller group and the first conveying surface, and a guide roller is provided between the scraping unit and the traction roller group. The scraping unit causes the material movement path between the guide roller and the first conveying surface to pass through the glue head of the scraping unit and form a wrapping angle with it. The scraping unit allows the movable adhesive applicator module to adapt to rolls of material without adhesive, improving the adaptability of the equipment.

[0014] Based on the presence of a guide roller, the guide roller is vertically adjustable on a translational support. The guide roller moves up and down to adjust the wrap angle. Moving the guide roller upwards reduces the wrap angle (i.e., increases the coverage area between the roll material and the rubber tip), resulting in a thinner rubber layer on the roll material. Moving the guide roller downwards increases the wrap angle (i.e., reduces the coverage area between the roll material and the rubber tip), resulting in a thicker rubber layer on the roll material. The thickness of the rubber layer is adjusted by moving the guide roller up and down. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Example

[0022] A movable adhesive applicator module is characterized by comprising a translation bracket 1, an unwinding shaft 2, a traction roller group 3, a suction conveying assembly, and a cutting assembly. The unwinding shaft 2, the traction roller group 3, the suction conveying assembly, and the cutting assembly are all mounted on the translation bracket 1. The translation bracket 1 can move left and right relative to the frame. The translation bracket 1 can move horizontally relative to the frame via a guide assembly. The guide assembly includes linear bearings 8 and a guide shaft. The linear bearings 8 are respectively fixedly disposed on the left and right sides of the translation bracket 1. The guide shaft is fixedly disposed on the frame. The linear bearings 8 are sleeved on the guide shaft. The translation bracket 1 moves left and right along the direction of the guide shaft. The translation bracket 1 can be driven and positioned by a screw drive mechanism. The method of locking the position after the translation bracket 1 moves is a conventional technical means for those skilled in the art. The unwinding shaft 2 is rotatably mounted at the end of the translation bracket 1; the traction roller group 3 is located downstream of the unwinding shaft 2. The traction roller group 3 includes an upper roller 31 and a lower roller 32. The upper roller 31 is rotatably mounted on a lifting seat 33, which is connected to a lifting power source. In this embodiment, the lifting seat 33 is driven by a cylinder to move the upper roller 31 up and down. The lower roller 32 is connected to a rotational power source that drives its rotation. A suction conveying assembly is located downstream of the traction roller group 3. The suction conveying assembly includes a first conveying surface 41 and a second conveying arc surface 51. Both the first conveying surface 41 and the second conveying arc surface 51 are provided with a plurality of suction holes 6. The discharge end of the first conveying surface 41 is connected to the inlet end of the second conveying arc surface 51. The discharge end of the second conveying arc surface 51 is connected to a conveying platform for conveying the material to be applied. The conveying platform is located below the second conveying arc surface 51 for easy observation of the adhesive application by the operator and for easy adjustment. The conveying speed of the conveying platform is equal to the conveying speed of the second conveying arc surface 51. Equal conveying speeds ensure that the roll material is flatly attached to the master sheet, avoiding excessive conveying speed of the master sheet, which could cause wrinkles in the master sheet when it is attached to the roll material, or excessive conveying speed of the roll material, which could cause wrinkles in the roll material when it is attached to the master sheet, thus affecting the yield rate.

[0023] See Figure 1 and Figure 2The first conveying surface 41 is disposed on the adsorption conveyor belt 4. The first conveying surface 41 is configured to be horizontal or inclined from top to bottom, preferably inclined from top to bottom, which can ensure that the roll material remains taut during conveying to a certain extent. In order to ensure the tension of the roll material, the conveying speed of the first conveying surface 41 is configured to be greater than the conveying speed of the traction roller group 3, so that the roll material is in a taut state. There are various ways to implement the speed of the first conveying surface 41 being greater than that of the traction roller group 3. For example, the power source of the first conveying surface 41 and the power source of the traction roller group 3 are set independently, and the speed difference between the two is achieved by inputting a set value. Alternatively, the adsorption conveyor belt 4 with the first conveying surface 41 and the traction roller group 3 share a power source. The power source is connected to the first synchronous pulley and the second synchronous pulley respectively through a synchronous belt. The first synchronous pulley is coaxially disposed with the drive roller of the adsorption conveyor belt 4, and the second synchronous pulley is coaxially disposed with the drive roller of the traction roller group 3 (see Figure 2 The drive roller (lower roller 32) is coaxially arranged, meaning that the angular velocities of the drive roller and the drive roller are the same. By setting the diameter of the drive roller to be larger than that of the drive roller, the conveying speed of the first conveying surface 41 driven by the drive roller is greater than the conveying speed of the traction roller group 3.

[0024] See Figure 3 and Figure 4 The second conveying arc surface 51 is disposed on the suction roller 5, which has a feeding station 54, a compound station 55, and a non-working station 56. The suction roller 5 includes a fixed base 52 and a rotating base 53, which rotates relative to the fixed base 52. The fixed base 52 is fixedly disposed on the translation bracket 1. The feeding station 54, the compound station 55, and the non-working station 56 are rotatably connected through the rotating base 53. The fixed base 52 includes a suction area and a windless area. The suction area has a groove 57 that communicates with a negative pressure source. The groove 57 is connected to the negative pressure source through an airtight pipe. Adsorption holes 6 are evenly distributed on the surface of the rotating seat 53 of the suction roller 5. The adsorption holes 6 at the feeding station 54 and the laminating station 55 communicate with the groove 57 of the suction area. The adsorption holes 6 at the feeding station 54 and the laminating station 55 have adsorption force, which can position the roll material. The laminating station 55 is the position where the roll material is laminated with the main sheet. The adsorption holes 6 at the laminating station 55 have adsorption force, which can ensure that the roll material is accurately applied to the main sheet. The adsorption holes 6 at the non-working station 56 are located in the windless area. When the roll material is laminated with the main sheet, the adsorption hole 6 moves to the non-working station 56 and loses its adsorption force, preventing the roll material from being carried away by the rotating seat 53, ensuring that the main sheet can stably enter the next process after being glued, and the equipment can work smoothly. The cutting assembly includes a cutter 71 for cutting the coil at the second conveyor arc surface 51. The cutter 71 cuts on a flat plane. See [reference needed]. Figure 3The adsorption holes 6 are arranged in pairs, and each group of adsorption holes 6 has a supporting surface between them. The supporting surface can cooperate with the cutter 71 to cut the roll material. The cutter 71 has a rotary cutting power source 73 that drives its rotation. The rotary cutting power source 73 drives the cutter 71 to cooperate with the cutting area on the rotating seat 53 to cut the material. The cutter 71 is fixedly mounted on the rotating seat 72. The rotary cutting power source 73 drives the rotating seat 72 to drive the cutter 71 to rotate and cut the roll material. The independent power source allows the cutter 71 to adapt to different adhesive application requirements, improving the adaptability of the equipment.

[0025] During machine adjustment, the translation bracket 1 can be moved left and right relative to the machine frame according to production needs. The lifting power source drives the lifting seat 33 to carry the upper roller 31 to move upward. After the material is fed, the upper roller 31 is driven to move downward to the position.

[0026] During operation, the unwinding shaft 2 unwinds the roll material with the adhesive layer, the traction roller group 3 outputs the roll material of a predetermined length, and the adsorption conveyor belt 4 with the first conveying surface 41 adsorbs and conveys the roll material. The adsorption holes 6 at the feeding station 54 and the compounding station 55 of the second conveying arc surface 51 have adsorption force. The compounding station 55 is the position where the roll material on the second conveying arc surface 51 intersects with the main order on the conveying platform. The adsorption holes 6 receive the roll material sent out by the first conveying surface 41 at the feeding station 54, and then carry the roll material into the compounding station 55 to compound with the main order on the conveying platform. The adsorption holes 6 then enter the non-working station 56 and lose their adsorption force to avoid moving the roll material and ensure the adhesive quality. Example

[0027] The roll material can be self-adhesive (like double-sided tape). This type of roll material only needs to be cut before lamination with the master sheet. However, for release paper roll materials, adhesive needs to be applied. To accommodate release paper roll materials, a scraping unit 9 is provided between the traction roller group 3 and the first conveying surface 41. The scraping unit 9 is existing technology. The scraping unit 9 scrapes the adhesive surface of the roll material. A guide roller 10 is provided between the scraping unit 9 and the traction roller group 3. See [link to relevant documentation]. Figure 5 The scraping unit 9 causes the material movement path between the guide roller 10 and the first conveying surface 41 to pass through the glue head of the scraping unit 9 and form a wrap angle with it. That is, a working surface is formed between the vertex of the first conveying surface 41 and the vertex of the guide roller 10. The glue head of the scraping unit 9 is lower than this working surface, so that the rolled material between the traction roller group 3 and the first conveying surface 41 forms a certain angle, i.e., a wrap angle. In order to adjust the glue layer thickness, the guide roller 10 is adjusted up and down on the translation bracket 1. The guide roller 10 moves up and down to adjust the size of the wrap angle. Two waist grooves 11 are provided on the translation bracket 1. The two ends of the guide roller 10 are respectively disposed in the waist grooves 11. The shaft core of the guide roller 10 is fixedly connected to the translation bracket 1 by a nut.

[0028] When adjusting the machine, the translation bracket 1 can be moved left and right relative to the machine frame according to production needs. The lifting power source drives the lifting seat 33 to carry the upper roller 31 to move upward. After the material is fed, the upper roller 31 is driven to move downward to the position. By adjusting the vertical position of the guide roller 10, the wrap angle can be adjusted to an appropriate size to ensure the thickness of the scraping glue.

[0029] During operation, the unwinding shaft 2 unwinds the roll material with the adhesive layer, and the traction roller group 3 outputs the roll material of a predetermined length. After the roll material is coated with adhesive by the scraping unit 9, it enters the first conveying surface 41 for adsorption and conveying. The subsequent work is the same as the corresponding work in Example 1, and will not be described again here.
