Description

Technical Field

[0001] This utility model relates to the field of impregnated paper processing and production technology, and in particular to an impregnated paper hydraulic roller device. Background Technology

[0002] Impregnated paper is made by immersing the paper web in a large amount of coating, allowing it to fully absorb the coating, and then scraping off the excess coating with a squeeze or scraper.

[0003] Existing pressure roller devices work by placing the impregnated paper web on a conveyor belt and conveying it under the pressure roller, which squeezes out excess coating. However, after being squeezed out, some of the excess coating adheres to the side wall of the paper web due to its own adhesiveness. When the paper web passes the pressure roller, it is absorbed again, resulting in the problem that the paper web cannot completely drain the excess coating. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide a hydraulic roller device for impregnating paper rolls, which is to scrape off the coating left on the side of the paper web.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hydraulic roller device for impregnating paper rolls includes a support base, a conveyor belt fixed on the support base and arranged in a front-to-back conveying direction, a squeeze roller fixed on the support base and located above the rear of the conveyor belt, a pair of scraping components respectively located on the left and right sides of the support base for scraping off the coating material from the paper web sidewall located below the squeeze roller, two liquid collection components respectively located on each scraping component for collecting excess coating material, and two positioning components respectively located below each scraping component for adjusting the position of the scraping components in the left-to-right direction.

[0007] Each scraping assembly includes a rotating main shaft vertically mounted on the corresponding side of the support base along the height direction, a connecting sleeve detachably mounted on the rotating main shaft and positioned between the extrusion roller and the conveyor belt, several fixed rods arranged circumferentially and fixed to the side wall of the connecting sleeve with their free ends extending between the extrusion roller and the conveyor belt, multiple elastic scraping components fixed to the free ends of the fixed rods in correspondence with each fixed rod, and a drive motor located at the lower end of the rotating main shaft.

[0008] Each of the drive motor output shafts is axially fixedly connected to the lower end of the corresponding rotating main shaft;

[0009] Each liquid collection assembly includes a liquid collection plate sleeved on the rotating main shaft and located below the conveyor belt, a splash guard fixed on the liquid collection plate along the height direction on the side away from the conveyor belt, a discharge tip set on the inner wall of the splash guard along the height direction, a liquid guide groove set on the side of the discharge tip along the height direction opposite to the rotation direction of the drive motor, and a liquid outlet fixed on the front side of the liquid collection plate with its front end inclined downward.

[0010] More preferably, each adjustment assembly includes an adjustment threaded post located below the collection tray, a sliding sleeve fixed to the lower side of the collection tray and threaded onto the adjustment threaded post, and a rotating motor fixed to the support base with its output shaft axially fixedly connected to the end of the adjustment threaded post away from the conveyor belt.

[0011] More preferably, two movable pulleys are fixedly provided on opposite sides of each of the liquid collection trays.

[0012] More preferably, each of the liquid collection trays is fixed with an elastic anti-leakage ring that is sealed to the corresponding rotating main shaft connection.

[0013] More preferably, each of the rotating spindles is provided with a threaded connection section on its upper part, each of the connecting sleeves is threadedly connected to the threaded connection section, each of the threaded connection sections is fixedly provided with an anti-disengagement plate at its lower end, and each of the threaded connection sections is threadedly connected with a fastening nut above the connecting sleeve.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model uses a scraping assembly to drive a motor to drive each scraping component to sequentially brush over and scrape off excess coating on the paper web sidewall located below the extrusion roller. The scraped coating is collected and accumulated by a liquid collection assembly, so that the scraping component that brushes over the paper web sidewall each time remains dry, achieving the effect of scraping off as much excess coating as possible from the paper web sidewall.

[0016] 2. This utility model adjusts the length distance between the fixed rod extending into the extrusion roller and the conveyor belt by adjusting the positioning component. Thus, when dealing with paper webs of different widths, the position of the scraper component can be adjusted so that the scraper abuts against and adheres to the side wall of the paper web.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an impregnation paperboard hydraulic roller device of this embodiment includes a support base 1, a conveyor belt 2 fixed on the support base 1 and arranged in the front-to-back direction, a squeeze roller 3 fixed on the support base 1 and located above the rear of the conveyor belt 2, a pair of scraping components 4 respectively disposed on the left and right sides of the support base 1 for scraping off the coating on the paper web sidewall located below the squeeze roller 3, two liquid collection components 5 respectively disposed on each scraping component 4 for collecting excess coating, and two positioning components 6 respectively disposed below each scraping component 4 for adjusting the position of the scraping component 4 in the left-to-right direction.

[0026] Each scraping assembly 4 includes a rotating main shaft 41 vertically disposed on the corresponding side of the support base 1 along the height direction, a connecting sleeve 42 detachably disposed on the rotating main shaft 41 and disposed at the position between the extrusion roller 3 and the conveyor belt 2, a plurality of fixed rods 43 arranged circumferentially and fixed to the side wall of the connecting sleeve 42 with their free ends extending between the extrusion roller 3 and the conveyor belt 2, a plurality of elastic scraping parts 44 fixed to the free ends of the fixed rods 43 in a one-to-one correspondence with each fixed rod 43, and a drive motor 45 disposed at the lower end of the rotating main shaft 41.

[0027] Each drive motor 45 output shaft is axially fixedly connected to the lower end of the corresponding rotating main shaft 41;

[0028] Each liquid collection assembly 5 includes a liquid collection plate 51 sleeved on the rotating main shaft 41 and located below the conveyor belt 2, a splash guard 52 fixed on the liquid collection plate 51 along the height direction on the side away from the conveyor belt 2, a discharge tip 53 provided on the inner wall of the splash guard 52 along the height direction, a liquid guide groove 54 provided on the side of the discharge tip 53 along the height direction opposite to the rotation direction of the drive motor 45, and a liquid outlet 55 fixed on the front side of the liquid collection plate 51 with its front end inclined downward.

[0029] In use, the impregnated paper web is laid flat on conveyor belt 2. Conveyor belt 2 transports the paper web backward. When it reaches the position directly below the squeeze roller 3, the paper web is subjected to the squeezing pressure between the squeeze roller 3 and the conveyor belt 2, causing the coating inside the paper web to overflow from the side wall. The drive motor 45 is started, driving the rotating main shaft 41 to rotate, causing each scraper 44 to rotate sequentially and brush over the side wall of the paper web, scraping off the coating left on the side wall of the scraper 44. The rotation continues, causing the scraper 44 to... When the side wall of scraper 44 passes the unloading tip 53, the tip of the unloading tip 53 abuts against the side wall of scraper 44, so that when scraper 44 rotates and brushes past the unloading tip 53, the coating on the side wall of scraper 44 is scraped off and flows down along the liquid guide groove 54 into the liquid collection plate 51. Thus, no coating is left on the surface of scraper 44 after passing the unloading tip 53. Therefore, when scraper 44 abuts against the side wall of paper web again, the coating on the side wall of paper web can be scraped off as much as possible, so as to further improve the scraping effect.

[0030] like Figure 1 , Figure 2 and Figure 5 As shown, each adjustment assembly 6 includes an adjustment threaded post 61 located below the collection tray 51, a sliding sleeve 62 fixed to the lower side of the collection tray 51 and threaded onto the adjustment threaded post 61, and a rotating motor 63 fixed to the support base 1 with its output shaft axially fixedly connected to the end of the adjustment threaded post 61 away from the conveyor belt 2.

[0031] When using this product, start the rotating motors 63 on both sides to drive the adjusting threaded columns 61 on both sides to rotate, causing the sliding sleeves 62 on both sides to move along the thread direction of the corresponding adjusting threaded columns 61 until the scraper 44 abuts against the side wall of the paper web, thus completing the adjustment. This allows the scraper 44 to be adjusted at the beginning when using paper webs of different widths and sizes, thereby adapting to different paper webs.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, each liquid collection plate 51 has two movable pulleys 7 fixed on opposite sides below it.

[0033] When this product is in use, the friction between the ground and the scraping assembly 4 is reduced by moving the pulley 7.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, each liquid collection tray 51 is fixed with an elastic anti-leakage ring 8 that is sealed and connected to the corresponding rotating main shaft 41.

[0035] When using this product, prevent the paint from seeping downwards, which could affect the operation of the drive motor 45.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, each rotating spindle 41 has a threaded connection section 411 on its upper part, and each connecting sleeve 42 is threadedly connected to the threaded connection section 411. Each threaded connection section 411 has an anti-detachment plate 412 fixed at its lower end, and each threaded connection section 411 has a fastening nut 413 threadedly connected above the connecting sleeve 42.

[0037] When using this product, the adjusting component 6 drives the scraper component 4 to move away from the conveyor belt 2, and then the fastening nut 413 is removed by rotation. Then the connecting sleeve 42 is loosened and removed, and the connecting sleeve 42 with the new scraper component 44 is replaced and tightened onto the threaded connection section 411. The connecting sleeve 42 is tightened until the lower side of the connecting sleeve 42 abuts against the upper side of the anti-detachment plate 412, thus completing the fixation. Then the fastening nut 413 is tightened to prevent the connecting sleeve 42 from loosening during rotation.

[0038] The working principle of this device is as follows:

[0039] Step 1: Lay the impregnated paper web flat on the conveyor belt 2. The conveyor belt 2 conveys the paper web backward. When it is conveyed to the position directly below the squeeze roller 3, the paper web is subjected to the squeezing pressure between the squeeze roller 3 and the conveyor belt 2, which causes the coating inside the paper web to overflow from the side wall of the paper web.

[0040] Step 2: Start the rotating motors 63 on both sides respectively, drive the adjusting threaded columns 61 on both sides to rotate, and cause the sliding sleeves 62 on both sides to move along the thread direction of the corresponding adjusting threaded columns 61 until the scraper 44 abuts against the side wall of the paper web, and the adjustment is completed.

[0041] Step 3: Start the drive motor 45 to drive the rotating main shaft 41 to rotate, causing each scraper 44 to rotate in sequence and brush over the side wall of the paper web, scraping off the paint left on the side wall of the paper web and leaving it on the side wall of the scraper 44. Continue to rotate, so that when the side wall of the scraper 44 passes the unloading tip 53, the tip of the unloading tip 53 abuts against the side wall of the scraper 44, so that when the scraper 44 rotates and brushes over the unloading tip 53, the paint on the side wall of the scraper 44 is scraped off and flows down along the liquid guide groove 54 into the liquid collection plate 51 and gathers.

[0042] Step 4: Users can place a storage box or similar container at the liquid outlet 55 to allow the paint collected in the collection tray 51 to flow out of the liquid outlet 55 and be stored in the storage box for reuse.

[0043] The above description is only a specific embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
