Description

Technical Field

[0001] This application relates to the field of processing technology for double-layer coils, and more specifically to automatic processing equipment for double-layer coils. Background Technology

[0002] Currently, most common double-layer rolls are formed by bonding two layers of paper together, such as double-layer paper rolls. It is known that double-layer rolls of the same type are generally thicker and more resilient than single-layer rolls of the same type, and therefore are more widely used in fields requiring high strength of the rolls, such as the logistics and packaging industries.

[0003] In the current bonding process of double-layer rolls, hot melt adhesives with high bonding strength are typically used as the bonding carrier. However, hot melt adhesives generally have high temperatures. If improper operation occurs when manually applying the adhesive to the bonding surface of at least one layer of the roll, burns can easily occur. Furthermore, after the adhesive is applied, manual intervention is required to overlap the two layers of rolls. Therefore, the degree of human intervention in the entire bonding process is high. Consequently, when bonding large quantities of double-layer rolls, the agility of manual operation gradually decreases, leading to longer completion times and lower overall efficiency in bonding double-layer rolls. Utility Model Content

[0026] refer to Figures 1 to 2 An automatic processing device for double-layer rolls according to a preferred embodiment of the present application will be described in detail below. The automatic processing device for double-layer rolls includes a device body 10, a feeding mechanism 20, a gluing assembly 30, and a winding assembly 40.

[0027] A material transfer channel 101 is formed inside the device body 10. Preferably, the material transfer channel 101 is arranged to pass through the opposite ends of the device body 10.

[0028] The unwinding mechanism 20 includes two unwinding shafts 21, two unwinding drive components 22, multiple material transfer shafts 23, and multiple material transfer drive components 24. The two unwinding shafts 21 are rotatably connected to opposite sides of the equipment body 10 forming the material transfer channel 101. The two unwinding shafts 21 are arranged opposite each other and spaced apart by keeping them parallel in the axial direction. A first material roll 91 and a second material roll 92 are respectively sleeved on the outer periphery of the two unwinding shafts 21.

[0029] The two unwinding shafts 21 are rotatably connected to two unwinding drive units 22.

[0030] It is worth mentioning that the first roll 91 and the second roll 92 are in a wound state when they are respectively fitted onto the two unwinding shafts 21. By activating the two unwinding drive units 22, the two unwinding shafts 21 are driven to rotate, so that the first roll 91 and the second roll 92 fitted onto the two unwinding shafts 21 are respectively unwound and begin to unwind.

[0031] Multiple material transfer shafts 23 are rotatably connected to opposite sides of the device body 10 forming the material transfer channel 101, and each material transfer shaft 23 is axially parallel to one of the unwinding shafts 21, and one material transfer shaft 23 is synchronously rotatably connected to one of the material transfer drive members 24.

[0032] Furthermore, the plurality of material transfer shafts 23 are divided into two groups of material transfer shafts 23, wherein one group of material transfer shafts 23 is used to transfer the first material roll 91, and the other group of material transfer shafts 23 is used to transfer the second material roll 92, and the latter half of the transmission path of the first material roll 91 and the latter half of the transmission path of the second material roll 92 intersect.

[0033] It is understood that each of the first roll 91 and the second roll 92 has one side that is respectively attached to the outer periphery of each of the two sets of material transfer shafts 23. Thus, when each of the material transfer drive members 24 is activated to rotate the corresponding material transfer shaft 23 along its respective axial direction, at least a portion of the end of the first roll 91, which is in a de-wound state, is stably transported by one of the two sets of material transfer shafts 23, and at least a portion of the end of the second roll 92, which is in a de-wound state, is stably transported by the other set of material transfer shafts 23.

[0034] Preferably, the two sets of transfer shafts 23 are respectively disposed at both ends of the transfer channel 101, and one set of the transfer shafts 23 is further divided into two teams of transfer shafts 23, which are evenly disposed at the top and bottom positions of the transfer channel 101 for transferring the first roll 91. Correspondingly, the other set of the two sets of transfer shafts 23 is further divided into two teams of transfer shafts 23, which are evenly disposed at the top and bottom positions of the transfer channel 101 for transferring the second roll 92. In this way, the lateral space occupied by the multiple transfer shafts 23 in the transfer channel 101 is reduced.

[0035] Preferably, the unwinding drive 22 is also connected to a side of the device body 10 that forms the material transfer channel 101 and is located outside the material transfer channel 101, and the unwinding drive 22 is implemented as a drive motor.

[0036] Preferably, each of the material transfer drive components 24 is connected to a side of the device body 10 forming the material transfer channel 101 and is located outside the material transfer channel 101, and each of the material transfer drive components 24 is implemented as a drive motor.

[0037] The gluing assembly 30 is used to apply glue to the side of the first roll 91 that is being transported by one of the two sets of material transfer shafts 23 away from the material transfer shaft 23.

[0038] The adhesive application assembly 30 includes an adhesive dispensing container 31, an adhesive guiding unit 32, an adhesive application shaft 33, and at least one adhesive application drive 34. The adhesive dispensing container 31 is disposed in the material transfer channel 101 of the device body 10, and its interior has an inlet 3101, an outlet 3102, and a cavity 3103 disposed between and communicating with both the inlet 3101 and the outlet 3102. The outlet 3102 is positioned towards one of the material transfer shafts 23 used to transfer the first roll 91, and its size increases along the axial direction corresponding to the material transfer shaft 23. The adhesive guiding unit 32 communicates with the inlet 3101 of the adhesive dispensing container 31, and is configured to guide the hot melt adhesive into the inlet 3101 by creating a negative pressure, gradually flowing out from the outlet 3102.

[0039] The adhesive application shaft 33 is disposed between the outlet 3102 of the adhesive dispensing container 31 and a material transfer shaft 23 facing the outlet 3102. The adhesive application shaft 33 maintains a distance from the port of the adhesive dispensing container 31 where the outlet 3102 forms, forming a first gap 301 of a predetermined size. The adhesive application shaft 33 also maintains a distance from a corresponding material transfer shaft 23, forming a second gap 302 of a predetermined size. Furthermore, the adhesive application shaft 33 remains axially parallel to either material transfer shaft 23. Figure 3 and Figure 4 As shown. The second gap 302 is used to allow the first roll 91 to pass through, that is, the first roll 91 gradually passes through the second gap 302 by being transported by a set of rotating conveyor shafts 23.

[0040] In addition, the adhesive application shaft 33 is rotatably connected to at least one of the adhesive application drive components 34.

[0041] Understandably, when the adhesive guiding unit 32 guides the hot melt adhesive into the inlet 3101 of the dispensing container 31 and out through the outlet 3102, since the adhesive spreading shaft 33 is located near the outlet 3102 of the dispensing container 31, the hot melt adhesive flowing out of the outlet 3102 continues to flow towards the adhesive spreading shaft 33 after passing through the first gap 301, and at least a predetermined thickness of hot melt adhesive is adhered to the outer peripheral surface of the adhesive spreading shaft 33. At the same time, the adhesive spreading drive 34 is activated. The adhesive applicator 33 is synchronously driven to rotate along its own axis, so that the outer peripheral surface of the adhesive applicator 33 is completely adhered with a predetermined thickness of hot melt adhesive. During this process, the surface of the adhesive applicator 33 with the hot melt adhesive adhered to it repeatedly passes through the second gap 302 as the adhesive applicator 33 rotates, so that the hot melt adhesive adhered to the outer peripheral surface of the adhesive applicator 33 is continuously applied to the side of the first roll 91 passing through the second gap 302, for bonding with the second roll 92.

[0042] Thus, the gluing component 30 automatically applies glue to the first roll 91 during transmission, replacing manual glue application and reducing manual intervention.

[0043] It is worth mentioning that the extension length of the outlet 3102 of the dispensing container 31 is adapted to the width of the first roll 91 transported by the corresponding material transfer shaft 23, and the axial length of the application shaft 33 is not less than the extension length of the outlet 3102. That is, after the application shaft 33 is adhered to by the hot melt adhesive flowing from the dispensing container 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 covered with hot melt adhesive.

[0044] Preferably, such as Figure 3 and Figure 4 As shown, the glue dispensing container 31 forms a glue dispensing part 311 facing the glue application shaft 33. The glue dispensing part 311 has a curved surface convex away from the location of the glue application shaft 33, and the outlet 3102 is provided to penetrate the curved surface of the glue dispensing part 311. The first gap 301 is formed between the curved surface of the glue dispensing part 311 and the outer periphery of the glue application shaft 33.

[0045] It should be noted that when the hot melt adhesive flowing out from the outlet 3102 adheres to the outer periphery of the rotating adhesive application shaft 33, the adhesive application part 311 has the curved surface, so that the hot melt adhesive adhering to the outer periphery of the adhesive application shaft 33 is scraped by the adhesive application part 311 when it leaves the first gap 301 through the rotation operation of the adhesive application shaft 33, so that the outermost part of the hot melt adhesive adhering to the adhesive application shaft 33 remains flat and is evenly applied to the predetermined side surface of the first roll 91.

[0046] Preferably, the adhesive guiding unit 32 is implemented to include a gear pump.

[0047] In a preferred embodiment, such as Figure 1 As shown, the number of adhesive application driving components 34 is set to two, and the two adhesive application driving components 34 are symmetrically arranged with respect to the material transfer channel 101. The two ends of the adhesive application shaft 33 are respectively connected to the driving ends of the two adhesive application driving components 34. In this way, compared with a single adhesive application driving component 34 driving the adhesive application shaft 33, the two adhesive application driving components 34 can drive the adhesive application shaft 33 more stably.

[0048] Preferably, each of the adhesive application drive components 34 is implemented as a drive motor, and the drive end of each drive motor is connected to one end of the adhesive application shaft 33, so that when each drive motor is started and its drive end rotates, the adhesive application shaft 33 is synchronously driven to rotate.

[0049] The adhesive application assembly 30 further includes at least one adjusting unit 35, which is used to adjust the size of the second gap 302 so that the first roll 91 is coated with a predetermined thickness of hot melt adhesive when it passes through the second gap 302.

[0050] Preferably, the adhesive application shaft 33 is driven to move and is disposed on at least one of the adjusting units 35, and the adhesive application shaft 33 moves relatively closer to and further away from a corresponding material transfer shaft 23 by being driven by at least one of the adjusting units 35, so that the size of the second gap 302 is adjusted.

[0051] Understandably, 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 adjusting units 35 is activated to drive the adhesive application shaft 33 to move closer to a corresponding transfer shaft 23, thereby reducing the second gap 302. That is, the distance between the adhesive application shaft 33 and the first roll 91 during transmission is reduced. As the first roll 91 is transmitted and passes through the second gap 302, the distance between the first roll 91 and the adhesive application shaft 33 is shortened because the second gap 302 is reduced, so that the rotating adhesive application shaft 33 reduces the thickness of the hot melt adhesive applied to the predetermined side of the first roll 91.

[0052] 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 adjusting units 35 is activated to drive the adhesive application shaft 33 to move away from the corresponding conveyor shaft 23, thereby increasing the second gap 302. That is, the distance between the adhesive application shaft 33 and the first roll 91 being conveyed increases. As the first roll 91 is conveyed and passes through the second gap 302, the distance between the first roll 91 and the adhesive application shaft 33 is increased due to the increased second gap 302, so that the rotating adhesive application shaft 33 gradually increases the thickness of the hot melt adhesive applied to the predetermined side of the first roll 91.

[0053] In one embodiment, each of the adjusting units 35 is configured as a hydraulic cylinder having a telescopic end, and a glue application drive 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 glue application drive 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 material transfer shaft 23 following at least one glue application drive 34, thereby adjusting the size of the second gap 302 and thus adjusting the glue application thickness of the glue application shaft 33.

[0054] In another embodiment, such as Figure 1 and Figure 2As shown, each of the pitch adjustment units 35 includes a pitch adjustment drive 351 and a transmission member 352, wherein each of the pitch adjustment drive members 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. A transmission member 352, driven by a pitch adjustment drive 351, moves a glue application drive 34 to move, causing the glue application shaft 33 to move relatively closer to and away from a corresponding material transfer shaft 23.

[0055] Preferably, each transmission component 352 includes a limiting track 3521, a screw 3522, and a sliding block 3523, wherein each limiting track 3521 is connected to the device body 10, and the extending direction of each limiting track 3521 is parallel to the moving direction of the adhesive application shaft 33. One screw 3522 is synchronously rotatably connected to one of the adjusting drive components 351. One sliding block 3523 is threadedly connected to the outer periphery of one screw 3522, and is slidably connected to one of the limiting tracks 3521. One adhesive application drive component 34 is connected to one of the sliding blocks 3523. Additionally, the adhesive dispensing container 31 is connected to at least one of the sliding blocks 3523.

[0056] Thus, when the screws 3522 in each of the adjusting units 35 are synchronously driven to rotate by their respective adjusting drive members 351, due to the limiting effect of the limiting rails 3521 in each of the transmission members 352, the sliding blocks 3523 in each of the transmission members 352 can only move along the axial direction of the driven screws 3522 on the corresponding limiting rails 3521, so that each adhesive application drive member 34 moves with each sliding block 3523, so that the adhesive application shaft 33 is driven as a whole to move relatively closer to and away from the corresponding material transfer shaft 23, thereby adjusting the size of the first gap 301.

[0057] Preferably, the pitch adjustment drive 351 is configured as a drive motor, and one end of the adhesive application shaft 33 is connected to the drive end of the drive motor.

[0058] In a preferred embodiment, specifically as follows: Figure 1As shown, the number of adhesive application drive components 34 is set to two, and the number of adjustment units 35 is set to two. Correspondingly, the number of adjustment drive components 351, limiting rails 3521, screws 3522, and sliding blocks 3523 are all set to two. The two adjustment drive components 351 are respectively connected to opposite sides of the device body 10 forming the material transfer channel 101. The two limiting rails 3521 are also respectively connected to opposite sides of the device body 10 forming the material transfer channel 101. The two screws 3522 are respectively rotatably connected to the two adjustment drive components 351. The two sliding blocks 3523 are respectively connected to the two screws 3522 by threaded connection. The two adhesive application drive components 34 are respectively connected to the two sliding blocks 3523. The adhesive dispensing container 31 is connected between the two sliding blocks 3523.

[0059] Thus, the adhesive application shaft 33 can be driven more stably by using two adjustment units 35 to move it compared to using one adjustment unit 35 to move it.

[0060] The winding assembly 40 is used to press the first roll 91 and the second roll 92 together at the intersection of the transport path of the first roll 91 and the transport path of the second roll 92, away from their respective transport shafts 23. Due to the adhesive effect of the adhesive applied to the side of the first roll 91 away from the transport shaft 23, the pressed first roll 91 and the second roll 92 are bonded together to form a combined roll.

[0061] Specifically, such as Figure 3 As shown, the winding assembly 40 includes a pair of winding rollers 41 and a pair of winding drive members 42. The two winding rollers 41 are arranged opposite to and spaced apart in the material transfer channel 101 of the equipment body 10, and both winding rollers 41 are axially parallel to any one of the material transfer shafts 23. A gap 4101 of a predetermined size is formed between the spaced two winding rollers 41. The gap 4101 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 4101 between the two winding rollers 41 at the same time.

[0062] Furthermore, the two winding rollers 41 are rotatably connected to the two winding drive members 42, so that when one end of the first roll 91 and one end of the second roll 92 pass through the gap 4101 between the two winding rollers 41 at the same time, the two winding drive members 42 are activated so that the two winding rollers 41 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 gluing assembly 30.

[0063] In this way, the automatic processing equipment for double-layer rolls automatically transmits the first roll 91 to the gluing assembly 30 through the feeding mechanism 20, so that the gluing assembly 30 automatically applies glue to the predetermined side of the first roll 91 passing through the second gap 302. At the same time, the feeding mechanism 20 also transmits the glued first roll 91 and the second roll 92 to the winding assembly 40 until both the first roll 91 and the second roll 92 have passed through the gap 4101 formed by the winding assembly 40. At this time, 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.

[0064] Preferably, the winding drive 42 is implemented as a drive motor.

[0065] Furthermore, the device body 10 also forms a recycling trough 102 in the bottom recess of the material transfer channel 101. The recycling trough 102 is connected to the material transfer channel 101, and the recycling trough 102 is located below the glue dispensing container 31 and the glue spreading shaft 33. The opening of the recycling trough 102 faces both the glue dispensing container 31 and the glue spreading 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 glue dispensing container 31 and the glue spreading shaft 33. In this way, the hot melt adhesive that flows out of the outlet 3102 and is not adhered to the glue spreading shaft 33 falls into the recycling trough 102 from the first gap 301 in a downward direction under the action of gravity, and gradually accumulates in the recycling trough 102 to await recycling operation.

[0066] Furthermore, the automatic processing equipment for double-layer rolls also includes a cooling component 50, 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 for simultaneously bonding the first roll 91 and the second roll 92.

[0067] Specifically, such as Figure 5As shown, the cooling assembly 50 includes a roller body 51 and a pair of feed members 52. The two ends of the roller body 51 are rotatably connected to the inner rings of the two feed members 52 and are located in the material transfer channel 101 of the device body 10. The roller body 51 is axially parallel to either of the material transfer shafts 23. The roller body 51 has an inlet channel 5101 and a cooling chamber 5102 communicating with the inlet channel 5101. The inlet channel 5101 is formed at one end of the roller body 51 for introducing coolant, and the cooling chamber 5102 is formed in the middle portion of the roller body 51 so that the coolant introduced into the inlet channel 5101 flows from the inlet channel 5101 to the cooling chamber 5102. Furthermore, the roller body 51 is arranged behind the adhesive application shaft 33 along the path of the first material roll 91, and the outer periphery of the roller body 51 is at least partially attached to the side of the first material roll 91 that contacts each of the material transfer shafts 23. The two feed transfer members 52 are rotatably connected to opposite sides of the device body 10 forming the material transfer channel 101.

[0068] Thus, when the first roll 91 is conveyed and passes through the outer periphery of the roller body 51, a predetermined amount of coolant has been introduced into the cooling chamber 5102 inside the roller body 51, 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.

[0069] Preferably, the roller body 51 further has an outlet channel 5103 communicating with the cooling chamber 5102. The outlet channel 5103 is formed at the other end of the roller body 51 away from the inlet channel 5101, and the cooling chamber 5102 is disposed between the inlet channel 5101 and the outlet channel 5103.

[0070] It should be noted that the end of the roller body 51 that forms the liquid inlet channel 5101 is connected to a device for providing coolant, so that coolant is introduced into the liquid inlet channel 5101. The end of the roller body 51 that forms the liquid outlet channel 5103 is connected to a collection device to collect the coolant flowing out of the liquid outlet channel 5103. Thus, when coolant is continuously introduced into the liquid inlet channel 5101 of the roller body 51, the coolant will be continuously introduced into the liquid inlet channel 5101, then flow through the cooling chamber 5102, and then flow out from the liquid outlet channel 5103, so that the coolant in the cooling chamber 5102 is continuously replaced, thereby preventing the cooling effect of the coolant in the cooling chamber 5102 from decreasing.

[0071] Preferably, each of the feeders 52 is implemented as a bearing, wherein the two ends of the roller body 51 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 material transfer channel 101.

[0072] Preferably, such as Figure 1 , Figure 2 and Figure 5 As shown, the cooling assembly 50 further includes at least one drive unit 53 for driving the roller body 51 to rotate. Preferably, each drive unit 53 includes a drive element 531 and a driving member 532, wherein each drive element 531 is mounted on the device body 10. One driving member 532 is drivably connected to one drive element 531, and one end of the roller body 51 is mounted to one driving member 532. The driving member 532 drives the roller body 51 to rotate by being driven by one drive element 531, so that the outer periphery of the roller body 51 is used for cooling.

[0073] Preferably, the driving element 531 is configured as a drive motor.

[0074] It is worth mentioning that each of the aforementioned driving components 532 is equipped with a belt pulley drive.

[0075] In a preferred embodiment, the number of drive units 53 is set to two, and the number of drive elements 531 and drive members 532 are both set to two. The two drive elements 531 are respectively installed on opposite sides of the device body 10 forming the material transfer channel 101, and are both located outside the material transfer channel 101, so as to drive the two drive members 532 respectively, thereby making the roller body 51 easily rotate.

[0076] In addition, the automatic processing equipment for double-layer rolls also includes a winding assembly 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 assembly 40.

[0077] Specifically, the winding assembly 60 includes a winding shaft 61 and a winding drive 62, wherein one end of the winding shaft 61 is synchronously rotatably connected to one of the winding drive 62, and the winding shaft 61 is rotatably connected to the device body 10 by being driven by the winding drive 62, and the winding shaft 61 is located in the material transfer channel 101 and is axially parallel to each of the material transfer shafts 23.

[0078] It is understood that when the winding drive 62 is activated, the winding shaft 61 is synchronously driven to rotate along its own axis and winds the combined roll formed by the bonding of the first roll 91 and the second roll 92 at the outer periphery.

[0079] Preferably, the winding drive 62 is also connected to a side of the device body 10 forming the material transfer channel 101 and is located outside the material transfer channel 101, and each of the winding 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.
