Description

Technical Field

[0001] The utility model relates to the technical field of toner production, in particular to a new type of toner pigment powdering machine. Background Art

[0002] Toner usually consists of pigments, fillers, additives, etc. Before use, toner usually needs to be ground into fine powder by a powdering machine. After long-term use of the powdering machine, the blades are prone to wear. After the blades are worn, it is not convenient to replace the blades, resulting in a reduction in the powdering effect of the powdering machine.

[0003] Based on the above problems, the patent with the publication number of CN220808103U discloses a toner production pigment powdering machine, which is provided with a blade replacement mechanism on the powdering barrel. During use, the worn blades can be quickly replaced to prevent the reduction of the powdering effect caused by blade wear, and solves the problem that the blades of the existing powdering machine are fixedly installed, and it is not convenient to replace the blades after the blades are worn, resulting in a reduction in the powdering effect of the powdering machine.

[0004] However, when implementing the above-mentioned toner production pigment powdering machine, it is found that it has at least the following problems. It can be found that during the use process, the blades need to crush the color masterbatch particles, and at the same time, the blades will also mix the crushed toner during the crushing process, which is one of the reasons why the blades are prone to wear. The reason is that the blades need to have a certain sharpness to crush the color masterbatch particles. Since the blades also need to mix the toner, during the mixing process, compared with the color masterbatch particles, the fine toner is more likely to wear the cutting edge of the blades, reducing the sharpness of the cutting edge. When the sharpness of the blades is insufficient, the blades mainly crush the color masterbatch particles through the impact force of high-speed rotation, which leads to the need to frequently replace the blades to ensure that the powdering effect of the powdering machine will not decrease.

[0017] 1. In the present utility model, the color masterbatch particles located inside the upper housing are driven by a motor to drive the first output shaft to drive the crushing blades for crushing. After the color masterbatch particles are crushed into color powder, they enter the lower housing through the filtration of the screen.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment: Please refer to Figures 1 to 4 , a technical solution is provided according to an embodiment of the present utility model: a new type of toner pigment powdering machine, including: a powdering machine housing 1, which includes an upper housing 101 and a lower housing 102, the upper housing 101 and the lower housing 102 are threadedly connected, and a feed port 2 is provided at the top of the upper housing 101. The upper housing 101 and the lower housing 102 are threadedly connected for the purpose of being more convenient during discharging; a crushing mechanism, the crushing mechanism is installed in the upper housing 101, which includes a motor 3, crushing blades 4 and a polygonal first output shaft 5, the first output shaft 5 is rotatably connected to the upper housing 101, the motor 3 is fixed at the top of the upper housing 101 and drives the first output shaft 5 to rotate, and the crushing blades 4 are fixedly spaced on the first output shaft 5; a stirring mechanism, which includes a stirring rod 6 and a polygonal second output shaft 7, the second output shaft 7 is rotatably connected to the inner bottom of the lower housing 102, and the stirring rod 6 is fixedly spaced on the second output shaft 7; a stratifying mechanism, which includes a sieve mesh 8 and a transmission member 9, a support ring 10 is provided on the inner wall of the lower housing 102, the support ring 10 can support the sieve mesh 8, the transmission member 9 is rotatably connected in the middle of the sieve mesh 8, and polygonal transmission grooves 11 adapted to the first output shaft 5 and the second output shaft 7 are provided at the top and bottom of the transmission member 9. It should be noted that after the sieve mesh 8 is placed on the support ring 10, the free end of the second output shaft 7 is inserted into the transmission groove 11 on the transmission member 9, and when the upper housing 101 and the lower housing 102 are threadedly connected, the free end of the first output shaft 5 can also be inserted into the transmission groove 11 on the transmission member 9. At this time, when the first output shaft 5 rotates, it drives the second output shaft 7 to rotate together through the transmission member 9.

[0027] The novel toner pigment pulverizer adopting the above structure pours color masterbatch particles along the feed port 2. Due to the restriction of the screen 8, the color masterbatch particles fall into the lower housing 102. At this time, the color masterbatch particles are located in the upper housing 101. The color masterbatch particles located in the upper housing 101 are driven by the motor 3 to drive the first output shaft 5 to drive the crushing blade 4 to crush. After the color masterbatch particles are crushed into toner powder, they enter the lower housing 102 through the filtration of the screen 8. At the same time, the first output shaft 5 drives the second output shaft 7 to rotate through the transmission member 9, and the second output shaft 7 drives the stirring rod 6 to mix the toner powder in the lower housing 102. This structure can separate the crushing of the color masterbatch particles from the mixing of the toner powder, enabling the crushing blade 4 to crush the color masterbatch particles and reducing the mixing of the toner powder, reducing the wear of the fine toner powder on the crushing blade 4, and solving the problem in the prior art that due to the need to mix the toner powder during the crushing process by the blade, the fine toner powder wears the edge of the blade, reducing the sharpness of the edge.

[0028] In this embodiment, the amount of color masterbatch particles crushed at one time is usually about 10 kilograms. After the filter screen supports the color masterbatch particles for a long time, it is prone to deformation and cause certain damage. To increase the load-bearing capacity of the filter screen, the screen 8 is fixed in the abutment ring 12, and a connecting ring 13 is fixed in the middle of the screen 8. Multiple support rods 14 are fixed between the connecting ring 13 and the abutment ring 12. The transmission member 9 is embedded and rotatably connected in the connecting ring 13. The screen 8 is supported by the multiple support rods 14 to increase the load-bearing of the screen 8 and prevent the screen 8 from deforming and breaking.

[0029] In this embodiment, since the first output shaft 5 needs to drive the second output shaft 7 to rotate together through the transmission of the transmission member 9 located in the connecting ring 13, during the initial crushing, due to the weight of the color masterbatch particles, the screen 8 will not rotate together with the first output shaft 5 driving the second output shaft 7 to rotate. However, when the color masterbatch particles located in the upper housing 101 are gradually crushed and filtered into the lower housing 102 by the screen 8, the weight of the color masterbatch particles supported by the screen 8 gradually decreases. At this time, the screen 8 is prone to rotate together with the first output shaft 5, affecting the screening of the screen 8. For this reason, a plurality of rotation-limiting protrusions 15 are provided at the bottom of the abutment ring 12, and a plurality of rotation-limiting grooves 16 adapted to the rotation-limiting protrusions 15 are formed on the support ring 10. By the cooperation of the rotation-limiting protrusions 15 at the bottom of the abutment ring 12 and the rotation-limiting grooves 16 on the support ring 10, the rotation of the abutment ring 12 is restricted.

[0030] In this embodiment, to prevent toner powder from spraying out along the gap at the threaded connection between the upper housing 101 and the lower housing 102, an external connecting piece 17 is fixed at the opening of the upper housing 101, and an annular threaded outer ring 18 is fixed at the opening of the lower housing 102. The threaded part of the threaded outer ring 18 protrudes from the opening of the lower housing 102. At the same time, the threaded outer ring 18 is threadedly connected. When the threaded outer ring 18 is threadedly connected to the external connecting piece 17, the opening of the upper housing 101 abuts against the opening of the lower housing 102. Through the cooperation of the threaded outer ring 18 and the external connecting piece 17, it is possible to prevent toner powder from spraying out along the gap and affecting the surrounding area.

[0031] In this embodiment, to prevent the powder dispenser from shaking excessively and tipping over during operation, a triangular support frame 19 is fixed on the outer wall of the lower housing 102. Through the support of the triangular support frame 19, a stable support is provided for the powder dispenser housing 1, reducing the shaking of the powder dispenser during operation and increasing stability.

[0032] In this embodiment, during the stirring process of the cylindrical stirring rod 6, it is not easy for the stirring rod 6 to stratify the toner powder. Instead, the stirring rod 6 is set to be square. Through the edges of the square stirring rod 6, the toner powder can be stratified up and down during the stirring process, increasing the mixing effect of the stirring rod 6.

[0033] Working principle:

[0034] S1. Installation process: Before pulverizing the masterbatch particles, first place the abutting ring 12 and the sieve 8 together on the support ring 10, so that the rotation-limiting protrusion 15 at the bottom of the abutting ring 12 is inserted into the rotation-limiting groove 16 on the support ring 10, and the free end of the second output shaft 7 is aligned with the transmission groove 11 on the transmission member 9. Insert the second output shaft 7 into the transmission groove 11. Then, threadedly connect the external connecting piece 17 at the opening of the upper housing 101 to the threaded outer ring 18 at the opening of the lower housing 102. At the same time, the first output shaft 5 is inserted into the transmission groove 11 on the transmission member 9. After the upper housing 101 rotates a certain degree, the upper housing 101 abuts against the lower housing 102 for sealing. Finally, pour the masterbatch particles into the powder dispenser housing 1 along the feed port 2. Since the masterbatch particles cannot fall through the gaps in the sieve 8 into the lower housing 102, before being broken, the masterbatch particles will be supported by the sieve 8 and located in the upper housing 101.

[0035] S2. Pulverizing and mixing: When the motor 3 is started, the first output shaft 5 drives the second output shaft 7 to rotate together through the transmission member 9. The crushing blade 4 fixed on the first output shaft 5 crushes the masterbatch particles in the upper housing 101. After the masterbatch particles are crushed into powder, the toner powder is screened by the sieve 8 and enters the lower housing 102, and the toner powder located in the lower housing 102 is mixed by the stirring rod 6 on the second output shaft 7.

[0036] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
