Description

Technical Field

[0001] The invention relates to the technical field of washing product production equipment, in particular to a washing tablet making device. Background Art

[0002] Laundry tablets are a new type of laundry product emerging in the market. They are in the form of sheets or strips, are light and easy to carry, can be quickly dissolved in water, and can be put into the washing machine instead of laundry detergent. Laundry tablets are made by a laundry tablet making machine, and the laundry raw materials are mixed and processed into a film.

This solution can meet the production needs of washing tablets of different thicknesses. In the actual production process, since the slurry is relatively thick, when the coating roller applies the slurry to the drying drum, after the pressure roller scrapes off the excess slurry, the slurry is easy to adhere to the surface of the pressure roller and the drying drum. After the slurry is hardened and formed, it is easy to affect its scraping effect, resulting in uneven slurry coating on the surface of the drying drum, which in turn causes the roll to be easily wrinkled during subsequent forming and winding, thus affecting the appearance of the laundry sheet and increasing the loss rate of the laundry sheet.

[0035] The following is combined with Figure 1-11 , an embodiment of a laundry tablet making device of the present invention is further described in detail.

[0036] A laundry tablet making device, such as Figure 1 , 2 As shown, it includes a frame 1, a drying drum 2 arranged on the frame 1 for drying and forming slurry, a slurry coating mechanism 3 for conveying slurry is arranged on one side of the drying drum 2, and a winding mechanism 5 for winding and forming laundry sheets is arranged on the other side, and a slitting mechanism 4 for scraping and cutting the laundry sheets is also arranged between the drying drum 2 and the winding mechanism 5, a scraping roller 6 for adjusting the thickness of the slurry is arranged on the slurry coating mechanism 3, and the rotation direction of the scraping roller 6 is opposite to the rotation direction of the drying drum 2, and a first online cleaning component 7 is located at the bottom end of the scraping roller 6 and abutted at a tangent position thereto; a second online cleaning component 8 for cleaning the surface of the drying drum 2 is arranged at a tangent position thereto at the bottom end of the drying drum 2, and the first online cleaning component 7 and the second online cleaning component 8 are linked and connected through a synchronous belt component.

[0037] Among them, Figure 4As shown, the first online cleaning component 7 includes a cleaning scraper 71 abutting against the bottom end of the scraper roller 6, a baffle plate 72 located on one side of the scraper roller 6, and a filter screen 73 arranged directly below the cleaning scraper 71. The side of the cleaning scraper 71 abutting against the scraper roller 6 is set as a rubber sheet or a brush sheet. The purpose of using a rubber sheet or a brush sheet for the cleaning scraper 71 is to avoid scratching the surface of the scraper roller 6, thereby preventing the slurry from easily forming agglomerates on the scraper roller 6, thereby affecting the uniformity of the slurry coating and the subsequent molding effect; and the cleaning scraper 71 is fixed to both ends of the scraper roller 6 through a hanging frame; the baffle plate 72 is arranged along the length direction of the cleaning scraper 71, and the baffle plate 72 is inclined toward the direction of the scraper roller 6 and tangent to its outer side wall; the filter screen 73 is detachably connected to the slurry coating mechanism 3.

[0038] Specifically, the cleaning scraper 71 is arranged at the bottom end of the scraper roller 6 and is arranged perpendicular to it, so that the surface of the scraper roller 6 can be cleaned online when the scraper roller 6 rotates, thereby scraping off the agglomerates attached to the outer surface of the scraper roller 6, ensuring that the surface of the scraper roller 6 is always flat and smooth, thereby improving the uniform effect of the slurry applied to the drying drum 2; the baffle plate 72 can adjust the angle as the scraper roller 6 rotates, thereby adjusting the amount of slurry temporarily stored between the coating roller 32 and the scraper roller 6, and changing the thickness of the slurry applied to the drying drum 2; in addition, the baffle plate 72 can also prevent the slurry from splashing, so that it slides along the direction of the baffle plate 72 to the filter screen 73 below, and flows back into the material trough 31 after being filtered by the filter screen 73. The filter screen 73 can filter out the agglomerates attached to the scraped slurry, thereby avoiding improving the purity of the slurry.

[0039] Specifically, Figure 5 and Fig. 9As shown, when the drying drum 2 is rotating, its rotation direction is generally counterclockwise. Since the drying drum 2 rotates counterclockwise, after the slurry is evenly applied and scraped and rolled, some small particles of agglomerates are likely to remain on the outer surface of the drying drum 2, which not only easily affects the uneven thickness of the slurry forming, but also easily leads to the deterioration of the slurry adhesion ability, which manifests as poor slurry hanging effect and other problems. For this reason, the agglomerates attached to the outer surface of the drying drum 2 can be cleaned by the second online cleaning component 8 vertically arranged at its bottom end. The second online cleaning component 8 It includes a booster nozzle 81 for spraying cleaning liquid, a roller brush 82 mounted on the outside of the booster nozzle 81 for cleaning attachments on the surface of the drying drum 2, and a water tank 83 located below the drum for receiving cleaning waste water. Both ends of the booster nozzle 81 are connected to a water pipe 84, and the bottom end of the water pipe 84 is connected to a water storage box 85. The water storage box 85 is arranged on the frame 1, and the water storage box 85 is located on both sides of the water tank; a plurality of spray holes 821 are evenly opened on the surface of the roller brush 82 at the position corresponding to the booster nozzle 81, and both ends of the roller brush 82 are rotatably connected to the scraper roller 6 through a synchronous belt. During the online cleaning process, the cleaning liquid or water stored in the water storage box 85 can be transmitted to the roller brush barrel through the water pipes 84 at both ends, and the booster nozzle 81 sprays the cleaning liquid or water through the spray hole 821 to the outer surface of the drying drum 2 by increasing the pressure, thereby dissolving the slurry agglomerates and reducing their adhesion; in addition, under the transmission action of the scraper roller 6, the roller brush 82 is synchronously driven to rotate in the direction opposite to the rotation direction of the drying drum 2, thereby increasing the friction between the roller brush 82 and the drying drum 2, and quickly scraping off the agglomerates on the outer surface of the drying drum 2. The cleaned wastewater will fall into the water tank 83 set below, which is convenient for unified and centralized discharge.

[0040] It is worth mentioning that, since the second online cleaning assembly 8 is arranged at the bottom end of the drying drum 2 and the second online cleaning assembly 8 performs cleaning work periodically, when the drying drum 2 heats and dries the slurry to form, the second online cleaning assembly 8 will not affect the process of the slurry being fed from the slurry coating mechanism 3 and unloaded from the slitting mechanism 4. Therefore, the drying drum 2 does not need to be stopped for cleaning, which can greatly improve the production efficiency of the laundry tablets.

[0041] It is worth noting that in order to retain the fragrance of the laundry tablets during the production process of the laundry tablets, the present invention provides a powdering mechanism 9 above the tangent point at the top of the drying drum 2 during the process of drying the slurry into shape by the drying drum 2. The powdering mechanism 9 stores powder containing fragrance, and the powdering mechanism 9 is used to evenly scatter the powder on the slurry so that the powder can adhere to the laundry tablets after the slurry is formed, thereby making the laundry tablets have their own fragrance.

[0042] Among them, Fig.10 , 11As shown, the powder sprinkling mechanism 9 includes a powder sprinkling drum 91 for storing powder, a protective cover 92 sleeved on the outside of the powder sprinkling drum 91, and a linkage assembly 93 for driving the powder sprinkling drum 91 to rotate intermittently. The powder sprinkling drum 91 is composed of an inner drum 911 and an outer drum 912. A plurality of powder screening holes 913 are equidistantly arranged on the surfaces of the inner drum 911 and the outer drum 912, and the inner drum 911 and the outer drum 912 have opposite directions of rotation; the protective cover 92 is clamped on both ends of the powder sprinkling drum 91, and the bottom end of the protective cover 92 is a bottom-free structure; the linkage assembly 93 is respectively sleeved between the powder sprinkling drum 91 and the drying drum 2, so as to synchronously drive the powder sprinkling drum 91 to rotate through the drying drum 2.

[0043] Specifically, when the drying drum 2 rotates to dry the slurry, a large amount of steam will be generated on its outer surface, and part of the steam will float into the powdering drum 91 along the upper side, so that the heat of the steam can be used to heat and dry the powder in the powdering drum 91, thereby avoiding the problem that the powder is easy to stick together in a humid environment; at the same time, in order to evenly discharge the powder, the powdering drum 91 is composed of an inner drum 911 and an outer drum 912, and the powder screening holes 91 on the surfaces of the inner drum 911 and the outer drum 912 are 3 is staggered, so that only when the powder sieving holes 913 on the inner drum 911 intersect with the powder sieving holes 913 of the outer drum 912 through rotation, the powder will be scattered along the powder sieving holes 913 into the slurry on the outer surface of the drying drum 2, and when the powder sieving holes 913 on the inner drum 911 are staggered with the powder sieving holes 913 of the outer drum 912, the inner drum 911 and the outer drum 912 block the powder sieving holes 913 with each other, so that they form a relatively closed space, thereby automatically completing the powder spreading operation.

[0044] Among them, the protective cover 92 on the powder spreading roller 91 can prevent water vapor from entering the powder, and the bottom-free structure of the protective cover 92 is convenient for unloading the powder and limiting the scattering direction of the powder; the rotation of the inner drum 911 and the outer drum 912 is driven by the linkage assembly 93, and the linkage assembly 93 includes a forward pulley, a reverse pulley and a transmission belt. The forward pulley is blocked at both ends of the outer drum 912, and the reverse pulley is blocked at both ends of the inner drum 911. The forward pulley and the reverse pulley are driven by gear meshing. The transmission belt is respectively arranged between the forward pulley and the drying drum 2, and the rotational force of the drying drum 2 is used to drive the powder spreading roller 91 to rotate, which can not only ensure the uniformity of powder spreading, but also save production costs.

[0045] In this embodiment, if Figure 8As shown, the slurry coating mechanism 3 includes a material trough 31 for storing recovered slurry, a coating roller 32 connected to the material trough 31 for foaming the slurry and transferring it to adhere to the outer peripheral surface of the drying drum 2, and a driving component 33 for driving the coating roller to rotate. The material trough 31 is located below the drying drum 2, and straight grooves 311 are opened on the two side walls of the material trough 31 at the position corresponding to the scraper roller 6; both ends of the coating roller 32 are rotatably connected to the side walls of the material trough 31 through the driving component 33, and the side walls of the coating roller 32 are abutted against the side walls of the drying drum 2; the rotation direction of the coating roller 32 is the same as the rotation direction of the drying drum 2.

[0046] Specifically, in order to avoid the problem of sedimentation of the slurry in the material tank 31, the coating roller 32 is arranged in the material tank 31, and part of the coating roller 32 is deposited below the liquid surface of the slurry, so that the slurry can be foamed when the coating roller 32 rotates, so that it is fully mixed and uniform, and when the slurry is coated on the outer peripheral surface of the drying drum 2, the rotation direction and speed of the coating roller 32 are adjusted to be consistent with the drying drum 2, so that the outer peripheral surface of the drying drum 2 can be evenly covered when the slurry is coated. At the same time, in order to further improve the feeding effect, one side of the coating roller 32 can be respectively It abuts against the sides of the drying drum 2 and the scraper roller 6, so that a storage space for temporary storage of slurry is formed in the upper part between the coating roller 32 and the drying drum 2. When the coating roller 32 brings the slurry to the drying drum 2, part of the slurry does not adhere to the surface of the drying drum 2 but remains on the coating roller 32. Since the scraper roller 6 is in contact with the coating roller 32, the slurry on the coating roller 32 that was originally going to fall back into the material trough 31 is left in the storage space. When the storage space is full, the slurry overflows, causing the slurry to flow over the coating roller 32 and contact the drying drum 2, thereby completing the loading and greatly improving the loading efficiency.

[0047] In order to allow the slurry to be dried according to a preset thickness after being loaded, a gap is provided between the scraper roller 6 and the drying drum 2, and a gap adjustment assembly 61 is provided at both ends of the scraper roller 6 to control the thickness of the slurry coating, wherein the gap adjustment assembly 61 comprises a first connecting rod 611, a second connecting rod 612 and a transmission hand wheel 613, wherein one end of the first connecting rod 611 is sleeved on the scraper roller 6, and the other end is hinged to the second connecting rod 612; the transmission hand wheel 613 is rotatably connected to the side wall of the material trough 31 through a bearing seat, and the transmission hand wheel 613 is rotatably connected to the second connecting rod 612.

[0048] Specifically, when adjusting the gap between the scraper roller 6 and the drying drum 2, the transmission hand wheel 613 is manually turned to drive the second connecting rod 612 to rotate. During the rotation of the second connecting rod 612, the first connecting rod 611 is synchronously driven to rotate. Since one end of the first connecting rod 611 is connected to the scraper roller 6, the scraper roller 6 moves with the first connecting rod 611. At the same time, due to the action of the straight groove 311 opened on the side wall of the material trough 31, the two ends of the scraper roller 6 can only perform linear reciprocating motion, and thus the gap between the scraper roller 6 and the drying drum 2 can be adjusted according to actual production needs, so that the coating thickness of the slurry can be controlled, which is convenient for producing laundry tablets of different thicknesses.

[0049] In this embodiment, if Figure 6 As shown, the slitting mechanism 4 includes a fixed bracket 41, a washing sheet scraper 42 and a slitting knife 43. The bottom end of the fixed bracket 41 is fixedly connected to the frame 1, and a lifting and adjusting component 44 is transmission-connected between the two sides of the fixed bracket 41 and the slitting knife 43; the front end of the washing sheet scraper 42 is set to a sharp angle, and the sharp end is attached to the outer surface of the drying drum 2; the slitting knife 43 is set above the washing sheet scraper 42, and the two ends of the slitting knife 43 are movably connected to the fixed bracket 41 through the lifting and adjusting component 44.

[0050] Specifically, after the drying drum 2 dries and forms the slurry, the slitting mechanism 4 will drive the washing sheet scraper 42 to abut against the outer edge of the drying drum 2, so as to use the sharp corners of the washing sheet scraper 42 to scrape the formed washing sheets attached to the outer surface of the drying drum 2, so that they are rolled up along the direction of the winding mechanism 5; after the winding is completed, since the drying drum 2 works without stopping, it is necessary to cut the washing sheets by the slitting knife 43, and in the cutting process, the slitting knife 43 is connected to the top of the fixed bracket 41, one end of the washing sheet scraper 42 is obliquely fixed to the fixed bracket 41, and a channel for rolling up the washing sheets is reserved between the slitting knife 43 and the washing sheet scraper 42, and the slitting knife 43 is driven to slide up and down along the fixed bracket 41 by the lifting and adjusting component 44, thereby prompting the slitting knife 43 to cut the washing sheets. The lifting and adjusting assembly 44 includes a lifting cylinder, a lifting guide rail and a slider. The lifting guide rail is arranged to fit the inner side of the fixed bracket 41. The lifting cylinder is fixed to the top of the fixed bracket 41, and the output end of the lifting cylinder is transmission-connected to the slider. The slider slides along the lifting guide rail, and the slider is clamped and connected to the two ends of the slitting knife 43.

[0051] In this embodiment, if Figure 2 and Figure 7As shown, the winding mechanism 5 includes a support frame 51, a traction roller 52, a tensioning roller 53 and a winding roller 54 which are rotatably connected to the support frame 51 in sequence, the traction roller 52 and the winding roller 54 are arranged at the same height, the tensioning roller 53 is smaller than the traction roller 52 and the winding roller 54, and the two ends of the winding roller 54 are movably connected with a correction component 55; the rotation speed ratio between the traction roller 52, the tensioning roller 53 and the winding roller 54 and the drying drum 2 is 1:2:1:1.

[0052] The traction roller 52 and the winding roller 54 are arranged at the same height as the winding roller 54, and the height of the tension roller 53 is smaller than that of the traction roller 52 and the winding roller 54, so that the tensioning force of the washing sheet can be relieved by the tension roller 53 when the washing sheet is rolled and unrolled, and the speed of the tension roller 53 is adjusted to the speed of the drying drum 2, so that the winding roller 54 can provide a buffering space for the winding roller 54, and the speed of the winding roller 54 can be kept consistent with the speed of the drying drum 2, so that the washing sheet can be stably wound, and the winding efficiency and flatness of the washing sheet can be greatly improved.

[0053] When winding, the web 54 will deviate due to the influence of the rotational force of the winding roller 54. Therefore, a correction assembly 55 is provided at both ends of the winding roller 54 to adjust the deviation direction in the reverse direction so that the web 54 can always be kept in the center position for winding. The correction assembly 55 includes a driving cylinder 551, a cylinder mounting seat 552, a correction guide rod 553 and a displacement sensor. The driving cylinder 551 is fixedly connected to the cylinder mounting seat 552, and the cylinder mounting seat 552 is obliquely fixed to the support frame 51; the correction guide rod 553 is connected in parallel to the cylinder mounting seat 552, and a correction slider 554 is slidably connected to the correction guide rod 553. One side of the correction slider 554 is connected to the rotating shaft of the winding roller 54 through a connecting piece, and the other side is connected to the output end of the driving cylinder 551 by transmission; the displacement transmission device is provided on the support frame 51 opposite to the edge of the washing sheet, and the displacement sensor is electrically connected to the driving cylinder 551. When the displacement sensor detects that the laundry sheet is offset during winding, it sends a signal to the driving cylinder 551. The driving cylinder 551 drives the correcting slider 554 to drive the winding wheel to slide left and right along the correcting guide rod 553, thereby decomposing the offset centrifugal force of the winding roller 54, so that the laundry sheet is always kept in the middle position for winding.

[0054] In this embodiment, if Figure 3As shown, a heat recycling and recovery system 10 for collecting steam generated during the drying process of the discharged slurry into sheets is also suspended above the drying drum 2; the heat recycling and recovery system 10 includes a heating mechanism 101 and a heat recovery mechanism 102, the heating mechanism 101 is arranged in the drying drum 2, and the heating mechanism 101 includes a steam generator 1011, a water vapor heat exchanger 1012 and a steam connecting pipe 1013, the steam generator 1011 is used to heat the drying drum 2, and the steam generator 1011 is connected to the water vapor heat exchanger 1012; one end of the steam connecting pipe 1013 is connected to the water vapor heat exchanger 1012, and the other end extends out of the drying drum 2 and is connected to the heat recovery mechanism 102. The steam generator 1011 is arranged inside the drying drum 2 to heat faster, so that the temperature of the drying drum 2 is more uniform, and the steam can be recycled.

[0055] Specifically, the heat recovery mechanism 102 includes a cover body 1021, an exhaust pipe 1022 and a filter plate 1023. The cover body 1021 is arranged above the drying drum 2, and the cover body 1021 is in the shape of a conical cover with an opening at the bottom; the exhaust pipe 1022 is connected to the top of the cover body 1021, and the other end of the exhaust pipe 1022 is connected to the water vapor heat exchanger 1012 through a steam connecting pipe 1013; the filter plate 1023 is detachably installed in the cover body 1021, and a drain pipe 1024 is connected to the end of the filter plate 1023. The drain pipe 1024 is used to allow the condensed water formed by the rising steam contacting the filter plate 1023 to flow into the drain pipe 1024 along the filter plate 1023 and be discharged through the drain pipe 1024. When the drying drum 2 heats and dries the slurry, the water vapor generated on its surface floats upward under the action of gravity. By arranging the cover body 1021 above the drying drum 2, the steam can be collected uniformly and centrally, and the exhaust gas contained in the steam is filtered by the filter plate 1023, and the residual heat in the steam will flow to the steam connecting pipe 1013 through the exhaust pipe 1022 at the top of the cover body 1021, and then flow back to the water vapor heat exchanger 1012 for recycling; by arranging the heat recovery mechanism 102, on the one hand, it can effectively prevent the condensed water formed by the steam rising and contacting the filter plate 1023 from falling vertically onto the laundry sheets on the drying drum 2, thereby affecting the production of the laundry sheets; on the other hand, it can also effectively and repeatedly recycle the heat of the steam, and recover it into the drying drum 2 for reheating, thereby avoiding energy waste and saving production costs.

[0056] Working principle of the present invention:

[0057] First, the heating mechanism 101 inside the drying drum 2 is opened to heat the outer surface of the drying drum 2, and the slurry coating mechanism 3 located on one side of the drying drum 2 coats the slurry in the material tank 31 on the outer peripheral surface of the drying drum 2 through the coating roller 32, and then the scraper roller 6 located on the side of the coating roller 32 evenly scrapes the slurry on the outer peripheral surface of the drying drum 2 to make its thickness uniform, and at the same time, the first online cleaning component 7 arranged at the bottom end of the scraper roller 6 automatically cleans the outer surface of the scraper roller 6; the steam generated in the process of drying the slurry is uniformly recycled and reused by the heat circulation recovery mechanism; then the drying drum 2 rotates counterclockwise, and the powder spreading mechanism 9 located at the top thereof evenly sprinkles a layer of powder on the slurry, and the slurry is quickly formed into laundry sheets after being heated by the drying drum 2, and is scraped off when it rotates to the slitting mechanism 4, and finally the winding mechanism 5 completes the winding work.

The same components are represented by the same figure marks.
