Description

Technical Field

[0001] This application relates to the field of processing technology for double-layer rolls, and more specifically to processing equipment for double-layer rolls with adjustable adhesive coating thickness. Background Technology

[0002] Currently, in some double-layer roll processing technology fields, hot melt adhesive is often used as a connecting carrier for bonding two layers of rolls together to form a combined roll.

[0003] However, in the process of using hot melt adhesive to bond two layers of material rolls, the hot melt adhesive is usually applied manually to one surface of one layer of the roll. Since it is difficult to maintain a consistent thickness of the hot melt adhesive applied manually, this can result in the adhesive being applied too thickly or too thinly at different locations on the roll surface. Consequently, during the subsequent bonding process using the hot melt adhesive, if the adhesive is too thick, a small amount of adhesive will be squeezed out from the bonded gap between the two layers and easily adhere to other surfaces of the rolls, causing contamination. Conversely, if the adhesive is too thin, the two layers will be difficult to bond stably together. Utility Model Content

[0004] To address the aforementioned technical problems and achieve at least one advantage of this application, this application provides a double-layer roll processing device with adjustable adhesive coating thickness, wherein the double-layer roll processing device with adjustable adhesive coating thickness includes:

[0030] refer to Figures 1 to 2 A preferred embodiment of the double-layer roll processing equipment with adjustable adhesive thickness according to this application will be described in detail below. The double-layer roll processing equipment with adjustable adhesive thickness includes a main body 10, a material transfer component 20 and an adhesive coating component 30.

[0031] An operating channel 101 is formed inside the main body 10 of the device. Preferably, the operating channel 101 is arranged to pass through the opposite ends of the main body 10 of the device.

[0032] The material transfer assembly 20 includes a plurality of material transfer rollers 21 and a number of material transfer drive members 22 equal to the number of material transfer rollers 21. The plurality of material transfer rollers 21 are rotatably connected to opposite sides of the equipment body 10 forming the operation channel 101, and two adjacent material transfer rollers 21 are kept axially parallel. Each material transfer roller 21 is synchronously rotatably connected to one material transfer drive member 22.

[0033] Furthermore, the plurality of transfer rollers 21 are divided into two groups of transfer rollers 21, wherein one group of transfer rollers 21 is used to transfer a first roll 91, and the other group of transfer rollers 21 is used to transfer a second roll 92, and the latter half of the transfer path of the first roll 91 and the latter half of the transfer path of the second roll 92 intersect.

[0034] It is understood that the first roll 91 and the second roll 92 each have one side that is respectively attached to the outer periphery of each of the two sets of transfer rollers 21 and are stably transported.

[0035] Preferably, the two sets of transfer rollers 21 are respectively disposed at both ends of the operating channel 101, and one of the sets of transfer rollers 21 is further divided into two teams of transfer rollers 21, which are evenly disposed at the top and bottom positions of the operating channel 101 for transferring the first roll 91. Correspondingly, the other set of transfer rollers 21 is further divided into two teams of transfer rollers 21, which are evenly disposed at the top and bottom positions of the operating channel 101 for transferring the second roll 92. In this way, the lateral space occupied by the multiple transfer rollers 21 in the operating channel 101 is reduced.

[0036] Preferably, each of the material transfer drive components 22 is connected to a side of the device body 10 forming the operation channel 101 and is located outside the operation channel 101, and each of the material transfer drive components 22 is implemented as a drive motor.

[0037] The adhesive application assembly 30 is used to apply hot melt adhesive to the side of the first roll 91 that is being transported by one of the two sets of transfer rollers 21 away from the transfer rollers 21.

[0038] Specifically, the adhesive application assembly 30 includes an adhesive dispenser 31, an adhesive guiding member 32, an adhesive application shaft 33, at least one adhesive application drive member 34, and at least one driving unit 35. The adhesive dispenser 31 has an inlet 3101, an outlet 3102, and a cavity 3103 disposed at and communicating with both the inlet 3101 and the outlet 3102. The outlet 3102 is positioned towards a transfer roller 21 used to transport the first roll 91, and extends along the axial direction of the corresponding transfer roller 21 to increase its opening size. The adhesive guiding member 32 communicates with the inlet 3101 of the adhesive dispenser 31, and is configured to guide the hot melt adhesive into the inlet 3101 by creating a negative pressure, and gradually flow out from the outlet 3102.

[0039] The coating shaft 33 is positioned between the glue outlet 3102 of the glue dispenser 31 and a transfer roller 21 facing the glue outlet 3102. The coating shaft 33 and the port of the glue dispenser 31 forming the glue outlet 3102 are spaced apart to form an adjustable first gap 301. The coating shaft 33 is also spaced apart from a corresponding transfer roller 21 to form an adjustable second gap 302. Furthermore, the coating shaft 33 is axially parallel to either transfer roller 21. The second gap 302 allows the first roll 91 to pass through; that is, the first roll 91 is gradually passed through the second gap 302 by being transported by a set of rotating transfer rollers 21.

[0040] One end of the glue-applying shaft 33 is rotatably connected to one of the glue-applying drive members 34, and the glue-applying shaft 33 is also driven and movably disposed on at least one of the drive units 35, and the glue-applying shaft 33 moves relatively closer to and further away from a corresponding transfer roller 21 by being driven by at least one of the drive units 35, so that the size of the second gap 302 is adjusted.

[0041] It is understood that when the adhesive guiding member 32 guides the hot melt adhesive to be introduced into the adhesive inlet 3101 of the dispensing device 31 and gradually flows out from the adhesive outlet 3102, since the dispensing shaft 33 is located near the adhesive outlet 3102 of the dispensing device 31, the hot melt adhesive flowing out from the adhesive outlet 3102 flows through the first gap 301 and at least partially flows to the dispensing shaft 33, so that the outer periphery of the dispensing shaft 33 is at least partially adhered with hot melt adhesive of a predetermined thickness. At the same time, at least one of the dispensing drive members 34 is activated to drive the dispensing shaft 33 synchronously to rotate along its own axis, so that the outer peripheral surface of the dispensing shaft 33 is completely adhered with hot melt adhesive of a predetermined thickness. In this process, the hot melt adhesive adhered to the outer periphery of the dispensing shaft 33 repeatedly passes through the second gap 302 with the rotating dispensing shaft 33 itself and is applied to a predetermined side of the first roll 91 that passes through the first gap 301 by transmission.

[0042] Thus, when it is necessary to reduce the thickness of the hot melt adhesive applied to a predetermined side of the first roll 91, at least one of the driving units 35 is activated to drive the coating shaft 33 to move closer to a corresponding transfer roller 21, thereby reducing the second gap 302. That is, the distance between the coating shaft 33 and the first roll 91 during transport is reduced. As the first roll 91 is transported through the second gap 302, the distance between the first roll 91 and the coating shaft 33 is shortened due to the reduced second gap 302, so that the rotating coating shaft 33 reduces the thickness of the hot melt adhesive applied to the predetermined side of the first roll 91.

[0043] When it is necessary to increase the thickness of the hot melt adhesive applied to a predetermined side of the first roll 91, at least one of the driving units 35 is activated to drive the coating shaft 33 away from the corresponding transfer roller 21, thereby increasing the second gap 302. That is, the distance between the coating shaft 33 and the first roll 91 being transported increases. As the first roll 91 is transported and passes through the second gap 302, the distance between the first roll 91 and the coating shaft 33 is increased due to the increased second gap 302, so that the rotating coating shaft 33 gradually increases the thickness of the hot melt adhesive applied to the predetermined side of the first roll 91.

[0044] In this way, by adjusting the size of the second gap 302 between the coating shaft 33 and the corresponding first roll 91, the hot melt adhesive adhered to the coating shaft 33 is correspondingly limited in its passage through the second gap 302 as the coating shaft 33 rotates, and is applied to the first roll 91, so that the thickness of the hot melt adhesive applied to the first roll 91 is correspondingly adjusted, thereby making the first roll 91 and the second roll 92 stably bonded to each other by the hot melt adhesive of a predetermined thickness to form a combined roll.

[0045] It is worth mentioning that the extension length of the glue outlet 3102 of the glue dispenser 31 is adapted to the width of the first roll 91 conveyed by the corresponding transfer roller 21, and the axial length of the coating shaft 33 is not less than the extension length of the glue outlet 3102. That is, after the coating shaft 33 is adhered to by the hot melt adhesive flowing from the glue dispenser 31, it directly applies the hot melt adhesive along the width direction of the first roll 91 to the portion of the first roll 91 that passes through the second gap 302, thereby ensuring that the portion of the first roll 91 that passes through the second gap 302 is coated with hot melt adhesive.

[0046] Preferably, the glue dispenser 31 forms a glue dispensing portion 311 facing the glue coating shaft 33. The glue dispensing portion 311 has a curved surface convex away from the location of the glue coating shaft 33, and the glue outlet 3102 is disposed through the curved surface of the glue dispensing portion 311. The first gap 301 is formed between the curved surface of the glue dispensing portion 311 and the outer periphery of the glue coating shaft 33.

[0047] It should be noted that when the hot melt adhesive flowing out from the dispensing port 3102 adheres to the outer periphery of the rotating coating shaft 33, the hot melt adhesive adhering to the outer periphery of the coating shaft 33 is scraped by the dispensing part 311 when it leaves the first gap 301 due to the rotation of the coating shaft 33. This keeps the outermost part of the hot melt adhesive adhering to the coating shaft 33 flat and is evenly applied to the predetermined side surface of the first roll 91.

[0048] Preferably, the adhesive guiding member 32 is implemented to include a gear pump.

[0049] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the number of the adhesive application drive 34 is set to two, and the two adhesive application drive 34 are symmetrically arranged with respect to the operation channel 101. The two ends of the adhesive application shaft 33 are respectively connected to the drive ends of the two adhesive application drive 34. In this way, compared with a single adhesive application drive 34 driving the adhesive application shaft 33, the two adhesive application drive 34 can drive the adhesive application shaft 33 more stably.

[0050] Preferably, each of the adhesive application drive components 34 is implemented as a drive motor for driving the adhesive application shaft 33 to rotate.

[0051] In one embodiment, each of the driving units 35 is configured as a hydraulic cylinder having a telescopic end, and one of the glue application driving members 34 is mounted on the telescopic end of one of the hydraulic cylinders. When the hydraulic cylinder is activated to extend or retract the telescopic end of the hydraulic cylinder, at least one of the glue application driving members 34 is driven to move along the extension or retraction direction of the telescopic end of the hydraulic cylinder, so that the glue application shaft 33 moves closer to and further away from a corresponding transfer roller 21 following at least one of the glue application driving members 34, so that the second gap 302 is adjusted in size, thereby adjusting the glue application thickness of the glue application shaft 33.

[0052] In another embodiment, such as Figure 1 and Figure 2As shown, each of the driving units 35 includes a driving member 351 and a transmission member 352, wherein each driving member 351 is mounted on the device body 10. A transmission member 352 is drivably connected to another transmission member 352, and a glue application drive 34 is mounted to another transmission member 352. The transmission member 352, driven by a driving member 351, moves the glue application drive 34 to move relative to the corresponding transfer roller 21, causing the glue application shaft 33 to move relatively closer to and away from the corresponding transfer roller 21.

[0053] Preferably, each transmission component 352 includes a guide rail 3521, a screw 3522, and a slider 3523, wherein each guide rail 3521 is connected to the device body 10, and the extending direction of each guide rail 3521 is parallel to the moving direction of the glue application shaft 33. One screw 3522 is synchronously rotatably connected to one drive component 351. One slider 3523 is threadedly connected to the outer periphery of one screw 3522, and one slider 3523 is slidably connected to one guide rail 3521. A glue application drive 34 is connected to one slider 3523. Additionally, the glue dispenser 31 is connected to at least one slider 3523.

[0054] Thus, when the screws 3522 in each of the driving units 35 are synchronously driven to rotate by their respective driving components 351, due to the limiting effect of the guide rails 3521 in each of the transmission components 352, the sliders 3523 in each of the transmission components 352 can only move along the axial direction of the driven screws 3522 on the corresponding guide rails 3521, so that each glue application drive 34 moves with each slider 3523, so that the glue application shaft 33 as a whole is driven to move relatively closer to and away from the corresponding transfer roller 21, thereby adjusting the size of the first gap 301.

[0055] Preferably, the driving member 351 is configured as a drive motor.

[0056] In a preferred embodiment, such as Figure 1 and Figure 2As shown, the number of adhesive application drive components 34 is set to two, and the number of driving units 35 is set to two. Correspondingly, the number of driving components 351, guide rails 3521, screws 3522, and sliders 3523 are all set to two. The two driving components 351 are respectively connected to opposite sides of the device body 10 forming the operating channel 101. The two guide rails 3521 are also respectively connected to opposite sides of the device body 10 forming the operating channel 101. The two screws 3522 are respectively rotatably connected to the two driving components 351. The two sliders 3523 are respectively connected to the two screws 3522 by threaded connections. The two adhesive application drive components 34 are respectively connected to the two sliders 3523. The glue dispenser 31 is connected between the two sliders 3523.

[0057] Thus, the glue-applying shaft 33 can be driven more stably by using two drive units 35 to move it compared to using one drive unit 35 to move it.

[0058] Preferably, the main body 10 of the device also has a recycling trough 102 recessed at the bottom of the operating channel 101. The recycling trough 102 is connected to the operating channel 101, and the recycling trough 102 is positioned below the dispensing device 31 and the coating shaft 33. The opening of the recycling trough 102 faces both the dispensing device 31 and the coating shaft 33. Preferably, the vertical projection area of ​​the recycling trough 102 is not less than the sum of the vertical projection areas of the dispensing device 31 and the coating shaft 33. Thus, the hot melt adhesive that flows out of the dispensing port 3102 and is not adhered to the coating shaft 33 falls from the first gap 301 into the recycling trough 102 under the action of gravity and gradually accumulates in the recycling trough 102, waiting for recycling.

[0059] Preferably, the material transfer assembly 20 further includes two unwinding shafts 23 and two unwinding drive components 24, wherein the two unwinding shafts 23 are rotatably connected to opposite sides of the equipment body 10 forming the operation channel 101, and the two unwinding shafts 23 are axially parallel to any one of the material transfer rollers 21, and the outer periphery of the two unwinding shafts 23 is respectively used to sleeve the first material roll 91 in the shape of a roll and the second material roll 92 in the shape of a roll.

[0060] The two unwinding shafts 23 are rotatably connected to the two unwinding drive members 24.

[0061] It is worth mentioning that the first roll 91 and the second roll 92 are in a wound state when they are respectively sleeved on the two unwinding shafts 23. By activating the two unwinding drive units 24, the two unwinding shafts 23 are driven to rotate, so that the first roll 91 and the second roll 92 sleeved on the two unwinding shafts 23 are respectively unwound and begin to unwind. The two sets of transfer rollers 21 are respectively used to transfer the unwound first roll 91 and the unwound second roll 92.

[0062] Furthermore, the double-layer roll processing equipment with adjustable adhesive thickness also includes a cooling component 40, which is used to cool the hot melt adhesive applied to the side of the first roll 91 to improve the bonding strength of the hot melt adhesive in subsequent bonding of the first roll 91 and the second roll 92 together.

[0063] Specifically, the cooling component 40 includes a cooling roller 41 and a pair of feed components 42. The two ends of the cooling roller 41 are rotatably connected to the inner rings of the two feed components 42 and are located in the operating channel 101 of the equipment body 10. The cooling roller 41 is axially parallel to either of the feed rollers 21. The cooling roller 41 has an inlet channel 4101 and a cooling chamber 4102 communicating with the inlet channel 4101. The inlet channel 4101 is formed at one end of the cooling roller 41 for introducing coolant, and the cooling chamber 4102 is formed in the middle portion of the cooling roller 41 so that the coolant introduced into the inlet channel 4101 flows from the inlet channel 4101 to the cooling chamber 4102. Furthermore, the cooling roller 41 is arranged behind the coating shaft 33 along the path of the first material roll 91, and the outer periphery of the cooling roller 41 is at least partially in contact with the side of the first material roll 91 that contacts each of the transfer rollers 21. The two transfer components 42 are rotatably connected to opposite sides of the equipment body 10 forming the operating channel 101.

[0064] Thus, when the first roll 91 is conveyed and passes through the outer periphery of the cooling roller 41, a predetermined amount of coolant has been introduced into the cooling chamber 4102 inside the cooling roller 41, causing the hot melt adhesive applied to a predetermined side of the first roll 91 to be cooled, thereby ensuring that the hot melt adhesive applied to the predetermined side of the first roll 91 meets the strong adhesion requirements between the first roll 91 and the second roll 92.

[0065] Preferably, the interior of the cooling roller 41 further has an outlet channel 4103 communicating with the cooling cavity 4102. The outlet channel 4103 is disposed at the other end of the cooling roller 41 away from the inlet channel 4101, and the cooling cavity 4102 is disposed between the inlet channel 4101 and the outlet channel 4103.

[0066] It should be noted that the end of the cooling roller 41 forming the inlet channel 4101 is connected to a device for providing coolant, so that coolant is introduced into the inlet channel 4101. The end of the cooling roller 41 forming the outlet channel 4103 is connected to a collecting device to collect the coolant flowing out of the outlet channel 4103. Thus, when coolant is continuously introduced into the inlet channel 4101 of the cooling roller 41, the coolant will be continuously introduced into the inlet channel 4101, then flow through the cooling chamber 4102, and then flow out from the outlet channel 4103, so that the coolant in the cooling chamber 4102 is continuously replaced, thereby preventing the cooling effect of the coolant in the cooling chamber 4102 from decreasing.

[0067] Preferably, each of the supply components 42 is implemented as a bearing, wherein the two ends of the cooling roller 41 are respectively connected to the inner rings of the two bearings, and the outer rings of the two bearings are connected to the opposite sides of the device body 10 forming the operating channel 101.

[0068] Preferably, the cooling component 40 further includes at least one drive unit 43 for driving the cooling roller 41 to rotate. Preferably, each drive unit 43 includes a drive element 431 and a driving member 432, wherein each drive element 431 is mounted on the device body 10. One driving member 432 is drivably connected to one drive element 431, and one end of the cooling roller 41 is mounted to one driving member 432. The driving member 432 drives the cooling roller 41 to rotate by being driven by one drive element 431, so that the outer periphery of the cooling roller 41 is used for cooling.

[0069] Preferably, the drive component 431 is configured as a drive motor.

[0070] It is worth mentioning that each of the aforementioned driving components 432 is implemented with a belt pulley drive device.

[0071] In a preferred embodiment, the number of drive units 43 is set to two, and the number of drive members 431 and drive components 432 is also set to two. The two drive members 431 are respectively installed on opposite sides of the device body 10 forming the operation channel 101, so as to drive the two drive components 432 respectively, thereby making the cooling roller 41 easily rotate.

[0072] Furthermore, the double-layer roll processing equipment with adjustable adhesive thickness also includes a winding component 50. The winding component 50 is used to press the first roll 91 and the second roll 92 against each other at the intersection between the transport path of the first roll 91 and the transport path of the second roll 92, away from their respective transport rollers 21. Due to the adhesive effect of the adhesive applied to the side of the first roll 91 away from the transport roller 21, the pressed first roll 91 and the second roll 92 are bonded together to form a combined roll.

[0073] Specifically, the winding member 50 includes a pair of rolling shafts 51 and a pair of rolling drive members 52. The two rolling shafts 51 are arranged opposite to and spaced apart in the operation channel 101 of the equipment body 10. Both rolling shafts 51 are axially parallel to any one of the transfer rollers 21. A gap 5101 of a predetermined size is formed between the spaced-apart rolling shafts 51. The gap 5101 is used only for the passage of the first roll 91 and the second roll 92 in transit. That is, one end of the first roll 91 and one end of the second roll 92 pass through the gap 5101 between the two rolling shafts 51 at the same time.

[0074] Furthermore, the two rolling shafts 51 are rotatably connected to the two rolling drive members 52, so that when one end of the first roll 91 and one end of the second roll 92 pass through the gap 5101 between the two rolling shafts 51 at the same time, the two rolling drive members 52 are activated so that the two rolling shafts 51 are driven to rotate and roll the first roll 91 and the second roll 92, so that the first roll 91 and the second roll 92 are bonded together by the hot melt adhesive applied by the adhesive application assembly 30.

[0075] In this way, the automatic processing equipment for double-layer rolls automatically transfers the first roll 91 to the gluing assembly 30 via the material transfer component 20, so that the gluing assembly 30 automatically applies glue to a predetermined side of the first roll 91 as it passes through the second gap 302. At the same time, the material transfer component 20 also transfers the glued first roll 91 and the second roll 92 to the winding member 50 until both the first roll 91 and the second roll 92 have passed through the gap 5101 formed by the winding member 50. At this point, the first roll 91 and the second roll 92 remain in contact with each other and are bonded together by hot melt adhesive, thereby reducing manual operation and improving the efficiency of bonding the first roll 91 and the second roll 92 together.

[0076] Preferably, the rolling drive 52 is implemented as a drive motor.

[0077] In addition, the double-layer roll processing equipment with adjustable adhesive thickness also includes a winding member 60, which is used to wind the first roll 91 and the second roll 92, which are held together by the pressing of the winding member 50.

[0078] Specifically, the winding member 60 includes a winding shaft 61 and a winding drive member 62, wherein one end of the winding shaft 61 is synchronously rotatably connected to one of the winding drive members 62, and the winding shaft 61 is rotatably connected to the equipment body 10 by being driven by the winding drive member 62, and the winding shaft 61 is located in the operation channel 101 and is axially parallel to each of the transfer rollers 21.

[0079] It is understood that when the roll drive 62 is activated, the roll shaft 61 is synchronously driven to rotate along its own axis and is wound around the combined roll formed by the bonding of the first roll 91 and the second roll 92 at the outer periphery position.

[0080] Preferably, the roll drive 62 is also connected to a side of the device body 10 forming the operation channel 101 and is located outside the operation channel 101, and each roll drive 62 is implemented as a drive motor.

The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
