Description

Technical Field

[0001] The utility model belongs to the technical field of toner screening, and specifically relates to a toner screening device. Background Art

[0002] Toner is a common name for pigments, which includes organic pigments, inorganic pigments, solvent dyes, fluorescent pigments, pearlescent pigments, fluorescent whitening agents, etc., and is widely used in industries such as plastics, paints, coatings, inks, textiles, leather, paper, building materials, and cultural and educational supplies.

[0003] Among them, before the toner is made into ink, it needs to be screened. After screening out the agglomerated and coagulated toner, it can be made into ink by water solubility.

[0004] Among them, the existing screening method is that workers hold a flat sieve for screening. This method is not only slow in screening, but also consumes a lot of physical strength and time of workers. Content of the Utility Model

[0005] The utility model provides a toner screening device to solve the defects in the prior art.

[0006] The utility model is realized through the following technical solutions:

[0007] A toner screening device includes a frame. A cylinder is arranged on the frame. The cross-section of the cylinder is circular and its diameter decreases from left to right. The cylinder is supported by a bracket and its axis is parallel to the ground. Both ends of the cylinder are through, with the left side being the discharge end and the right side being the feed end. A strip-shaped groove is opened along the length direction of the side surface of the cylinder, and the strip-shaped groove penetrates to the discharge port of the cylinder. A plurality of strip-shaped grooves are evenly arranged along the circumferential direction of the cylinder. A filter screen is attached and fixedly connected to the outer side surface of the cylinder. The cylinder is driven by a driving device to rotate along its axis. A cross bar is fixedly arranged on the upper part of the cylinder, and a brush that can contact the filter screen is fixedly connected downward from the bottom surface of the cross bar. A receiving tray is arranged below the cylinder.

[0008] When this application is in use, workers pour the coloring material into the cylinder. The cylinder is driven by a driving device to rotate along its axis. Since the cross-section of the cylinder is circular and its diameter decreases from left to right and under the action of centrifugal force, the qualified toner passes through the filter screen and the strip-shaped groove and falls into the receiving tray, while the unqualified agglomerated toner blocks or particles flow out through the discharge port of the strip-shaped groove, thereby realizing the separation of toner and toner blocks. This not only saves the time and physical strength consumed by manual screening of workers, but also can achieve rapid screening and improve the screening efficiency. The brush can contact the filter screen when needed to realize reverse cleaning of the filter screen and prevent the smooth discharge of toner caused by the accumulation of toner on the filter screen.

[0009] Preferably, the frame includes a horizontal plate and support rods fixedly arranged at the four corners of the bottom surface of the horizontal plate. The support includes a vertical column and a support block fixedly arranged on the horizontal plate. A connecting rod is fixedly arranged inside the discharging side of the cylinder body. The connecting rod is vertically connected with a rotating rod coaxial with the cylinder body. The rotating rod passes through the vertical column and is rotatably connected with the vertical column through a bearing. An annular plate is sleeved outside the feeding end of the cylinder body. An arc-shaped support groove adapted to the annular plate is formed on the top surface of the support block. The material receiving tray is arranged on the horizontal plate. The rotating rod passes through the vertical column and is rotatably connected with the vertical column through a bearing, realizing the support for the left end of the cylinder body. The cooperation between the annular plate and the arc-shaped support groove realizes the support for the right end of the cylinder body, and the rotation of the cylinder body can be ensured under the action of the annular plate and the rotating rod.

[0010] Preferably, the driving device includes a driven gear ring sleeved on the cylinder body and a driving motor fixedly arranged on the horizontal plate. A driving gear meshing with the driven gear ring is coaxially sleeved on the rotating shaft of the driving motor. The rotation of the rotating shaft of the driving motor drives the driving gear to rotate, and the driving gear drives the driven gear ring to rotate, thereby driving the cylinder body to rotate along its axis.

[0011] Preferably, ball cavities are formed on the inner walls of the bottom surface and both sides of the arc-shaped support groove. Ball bearings in the ball cavities are in contact with the corresponding side surfaces of the annular plate. The ball bearings can replace the sliding friction between the annular plate and the arc-shaped support groove with rolling friction, thereby reducing the friction force.

[0012] Preferably, a feeding pipe is fixedly arranged on one side of the cylinder body. The lower end of the feeding pipe inclines downward towards the feeding port of the cylinder body. The upper end of the feeding pipe is communicated with a feeding hopper. Through the cooperation of the feeding hopper and the feeding pipe, it is convenient to feed materials into the cylinder body.

[0013] Preferably, a discharging groove is formed on the top surface of the horizontal plate. A storage barrel is arranged below the discharging groove and is opposite to the discharging port of the cylinder body. The storage barrel can facilitate the recovery of the filtered toner blocks and particles, avoiding direct discard and reducing waste.

[0014] Preferably, telescopic rods are fixedly arranged on both the feeding pipe and the vertical column. The two telescopic rods are vertically arranged and their movable ends are fixedly connected to the bottom surface of the cross bar. The extension and retraction of the electric telescopic rods can make the brush contact or not contact the filter screen, thereby ensuring that the filter screen contacts the brush when needed and the filter screen is away from the brush when not needed.

[0015] The beneficial effects of the present utility model are as follows: By using this application, the separation of toner can be driven by the rotation of the cylinder body, thus saving the time and physical strength consumed by the staff in manually screening the toner. Since the screened toner blocks can automatically fall out of the cylinder body when the cylinder body rotates, there is no need to manually pour them out, thereby improving the screening efficiency.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0022] A toner screening device, as Figure 1 and Figure 2 shown. It includes a frame, on which a cylinder body 1 is provided. Specifically, the frame includes a cross plate 9 and struts fixedly arranged at the four corners of the bottom surface of the cross plate 9. The support includes a column 7 and a support block 8 fixedly arranged on the cross plate 9. An connecting rod is fixedly arranged inside the discharge side of the cylinder body 1. The connecting rod is vertically connected to a rotating rod coaxial with the cylinder body 1. The rotating rod passes through the column 7 and is rotatably connected to the column 7 through a bearing. The outer side of the feed end of the cylinder body 1 is sleeved with a ring plate 12. An arc-shaped support groove 10 adapted to the ring plate 12 is provided on the top surface of the support block 8. The material receiving tray 6 is arranged on the cross plate 9.

[0023] The cross-section of the cylinder body 1 is circular and its diameter decreases from left to right. The cylinder body 1 is supported by a bracket and its axis is parallel to the ground. Both ends of the cylinder body 1 are through, with the left side being the discharge end and the right side being the feed end. A strip-shaped groove 2 is provided along the length direction of the side surface of the cylinder body 1, and the strip-shaped groove 2 penetrates to the discharge port of the cylinder body 1. A plurality of strip-shaped grooves 2 are evenly arranged along the circumferential direction of the cylinder body 1. A filter screen 3 is attached and fixedly connected to the outer side surface of the cylinder body 1.

[0024] The cylinder body 1 is driven to rotate along its axis by a driving device. The driving device includes a driven gear ring 14 sleeved on the cylinder body 1 and a driving motor 11 fixedly arranged on the cross plate 9. The rotating shaft of the driving motor 11 is coaxially sleeved with a driving gear 13 meshing with the driven gear ring 14. A cross bar 4 is fixedly arranged on the upper part of the cylinder body 1, and a brush 5 that can contact the filter screen 3 is fixedly connected downward from the bottom surface of the cross bar 4. A material receiving tray 6 is provided below the cylinder body 1.

[0025] When this application is in use, the worker pours the colorant into the cylinder body 1. The cylinder body 1 is driven to rotate along its axis by the driving device. Since the cross-section of the cylinder body 1 is circular and its diameter decreases from left to right and under the action of centrifugal force, the qualified color powder passes through the filter screen 3 and the strip-shaped groove 2 and falls into the material receiving tray 6, while the unqualified agglomerated color powder blocks or particles flow out through the discharge port of the strip-shaped groove 2, thereby realizing the separation of the color powder and the color powder blocks. This not only saves the time and physical strength consumed by the worker's manual screening, but also can achieve rapid screening and improve the screening efficiency. The brush 5 can contact the filter screen 3 when needed to realize the reverse cleaning of the filter screen 3 and prevent the poor discharge of the color powder caused by the accumulation of the color powder on the filter screen 3.

[0026] Wherein, the rotating rod passes through the column 7 and is rotationally connected with the column 7 through a bearing to realize the support of the left end of the cylinder body 1. The cooperation between the annular plate 12 and the arc-shaped support groove 10 realizes the support of the right end of the cylinder body 1 and can ensure the rotation of the cylinder body 1 under the action of the annular plate 12 and the rotating rod.

[0027] The rotation of the rotating shaft of the driving motor 11 drives the driving gear 13 to rotate, and the driving gear 13 drives the driven gear ring 14 to rotate, thereby driving the cylinder body 1 to rotate along its axis.

[0028] The bottom inner wall and both side inner walls of the arc-shaped support groove 10 are provided with ball 15 cavities, and balls 15 in contact with the corresponding side surfaces of the annular plate 12 are arranged in the ball 15 cavities. The balls 15 can replace the sliding friction between the annular plate 12 and the arc-shaped support groove 10 with rolling friction, thereby reducing the friction force.

[0029] One side of the cylinder body 1 is fixedly provided with a feed pipe 16. The lower end of the feed pipe 16 inclines downward towards the feed inlet of the cylinder body 1. The upper end of the feed pipe 16 is communicated with a feed hopper 17. A discharge groove is formed on the top surface of the cross plate 9. A storage barrel 18 is arranged below the discharge groove. The discharge groove is opposite to the discharge outlet of the cylinder body 1. Through the cooperation of the feed hopper 17 and the feed pipe 16, it is convenient to feed materials into the cylinder body 1. Through the storage barrel 18, it is convenient to recycle the filtered color powder blocks and particles, avoid direct discard, and reduce waste.

[0030] Expansion rods 19 are fixedly arranged on both the feed pipe 16 and the column 7. The two expansion rods 19 are arranged vertically and their movable ends are fixedly connected to the bottom surface of the cross bar 4. The elongation and shortening of the electric expansion rods 19 can make the brush 5 contact or not contact the filter screen 3, so as to ensure that when needed, the filter screen 3 contacts the brush 5, and when not needed, the filter screen 3 is away from the brush 5.

[0031] During the use of this application, the rotation of the cylinder body 1 can drive the separation of the color powder, thus saving the time and physical strength consumed by the staff for manual screening of the color powder. Since the screened color powder blocks can automatically fall out of the cylinder body 1 when the cylinder body 1 rotates, there is no need to manually pour them out, and thus the screening efficiency can be improved.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
