[0003] In the processing of raw lacquer paste, due to its thick texture, it needs to be ground to make it more delicate, glossier and more durable. In the prior art, a three-roll grinder is used to grind the material through three rollers with different rotation speeds. The three rollers rotate at different speeds, so that the material is sandwiched between the rollers. Under the action of friction and shear, the raw lacquer paste is ground, dispersed and evenly mixed.

[0004] However, when grinding raw lacquer paste with the existing three-roll grinder, for example, when manually controlling the feeding, the amount of raw lacquer feed will deviate during the repeated feeding operation, that is, the three-roll grinder will have too much raw lacquer feed. At this time, the grinding operation of the three-roll grinder needs to be stopped, delaying the normal operation of the grinding process. For this reason, a raw lacquer paste grinding device is proposed. Utility Model Content

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] like Figure 1-4As shown, a raw lacquer paste grinding device in this embodiment includes a three-roll grinder 1, a frame 2, a feed hopper 3 and a discharge control mechanism 4, wherein the three-roll grinder 1 is based on the different rotation speeds of the three rollers, so that the material is clamped between the rollers, and the raw lacquer paste is ground, dispersed and evenly mixed under the friction and shearing action. This is the prior art, and its structural design is not repeated here, and the front side and the upper side of the frame 2 are both open, that is, the frame 2 has four sets of side walls of left, right, bottom and back, and the frame 2 also has a accommodating interval, which is the space between the four sets of side walls. Area, and the three-roll grinder 1 is placed in this accommodating area, and the feed hopper 3 is detachably connected to the accommodating area of ​​the frame seat 2, and is located above the three-roll grinder 1, and has a storage space in the feed hopper 3, and this storage space is filled with raw lacquer paste, so that the raw lacquer paste in the feed hopper 3 can be smoothly introduced into the three-roll grinder 1. In addition, the discharge control mechanism 4 includes a baffle 1 41, a baffle 2 42 and a drive assembly, wherein the baffle 1 41 and the baffle 2 42 are arranged at the outlet of the feed hopper 3 in a close fit with each other, and move toward or away from each other through a cycle of the drive assembly.

[0031] It should be noted that if Figure 3 As shown, the feed hopper 3 has a structure that is wide at the top and narrow at the bottom, which can facilitate feeding and will not discharge too much material at one time. Baffle 2 42 is located on the side close to the frame seat 2, and baffle 1 41 is located on the side away from the rear side wall of the frame seat 2. In addition, the sum of the lengths of baffle 1 41 and baffle 2 42 when viewed from the left is greater than the length of the outlet of the feed hopper 3 when viewed from the left.

[0032] When designed in this way, in the intermittent discharge design, the raw lacquer paste in the feed hopper 3 can be discharged intermittently, the discharge amount of the raw lacquer paste in the feed hopper 3 can be kept relatively consistent, and the three-roll grinder 1 will not be fed with too much raw lacquer paste, thereby ensuring that the grinding operation can continue normally and that the three-roll grinder 1 will not be shut down.

[0033] In order to facilitate understanding of the structure and location of the drive components, a detailed description is given here. Figure 4As shown, first, the driving assembly includes a driving component, a gear 43, a rack 1 44 and a rack 2 45, wherein the rack 1 44 and the rack 2 45 are respectively connected to the baffle 1 41 and the baffle 2 42 correspondingly, and the corresponding connection here refers to the baffle 1 41 being fixedly provided with a connecting bar 1 46 fixedly connected to the rack 1 44, and the baffle 2 42 being fixedly provided with a connecting bar 2 47 fixedly connected to the rack 2 45, so that the rack 1 44 and the baffle 1 41 can move synchronously, the rack 2 45 and the baffle 2 42 can move synchronously, and the rack 1 44 and the rack 2 45 are respectively meshed on the upper and lower sides of the gear 43, and are movably connected to the frame seat 2, the gear 43 is rotatably connected to the frame seat 2, and the driving component is detachably connected to the frame seat 2, so that when the gear 43 is transmitted, the rack 1 44 and the rack 2 45 move toward or away from each other.

[0034] The description of the movably connected rack 1 44 and rack 2 45 with the frame seat 2 is as follows: Figure 3 and 4 As shown, the number of gears 43, racks 1 44 and racks 2 45 are each two groups, and two groups of slide rails 5 are fixedly provided on the left and right side walls of the frame seat 2 by bolts, that is, the number of slide rails 5 is four groups in total, and the slide rails 5 are arranged horizontally, and the racks 1 44 and racks 2 45 are respectively slidably connected to the corresponding slide rails 5, so that the racks 1 44 and racks 2 45 can only move horizontally.

[0035] Furthermore, since there are various designs of driving components, for ease of understanding, two designs of driving components are provided in this application.

[0036] In one embodiment, if Figure 5 and 6 As shown, the driving component is an electric push rod 48, which is fixed to the rear side wall of the frame seat 2 by bolts, and the telescopic end of the electric push rod 48 is fixedly connected to the rack 44.

[0037] In this way, the electric push rod 48 is started, and the telescopic effect of the electric push rod 48 is utilized to make the rack 1 44 move back and forth in a cycle. During the process of the rack 1 44 moving back and forth in a cycle, the gear 43 is used to transmit the transmission, so that the rack 2 45 and the rack 1 44 move in a cycle in directions toward or away from each other, and the baffle 1 41 and the baffle 2 42 will also move in a cycle toward or away from each other in this process, so as to realize the intermittent discharge of the raw lacquer paste in the feed hopper 3. Firstly, the discharge amount of the raw lacquer paste in the feed hopper 3 can be kept relatively consistent, and the three-roll grinder 1 will not be fed with too much raw lacquer paste, so as to ensure that the grinding operation can be carried out normally and continuously and the three-roll grinder 1 will not be shut down.

[0038] In another embodiment, if Figure 1-4As shown, the driving component is a motor 49, which is fixed to the right side of the frame seat 2 by bolts. The output end of the motor 49 is connected to the gear 43. When the gear 43 rotates, the rack 1 44 and the rack 2 45 will move towards or away from each other.

[0039] It should be noted that when the motor 49 is started, it is necessary to ensure the forward and reverse rotation of the cycle. At this time, the motor 49 needs to use a relay and a PLC controller, that is, the motor 49 uses the basic logic instructions of the PLC to control the forward and reverse rotation of the motor 49. For example, the motor 49 rotates forward for three seconds, stops for two seconds, reverses for three seconds and stops for two seconds. This cycle repeats until the work is completed. Since the motor 49 uses a relay and a PLC controller to cycle forward and reverse, which is a prior art, it will not be elaborated here, and the relay and the PLC controller are not shown in the figure.

[0040] When designed in this way, when the motor 49 is started to cycle forward and reverse, the motor 49 will drive the gear 43 to cycle forward and reverse, and the rack 2 45 and the rack 1 44 will cycle in opposite directions or move away from each other. Similarly, the baffle 1 41 and the baffle 2 42 will also cycle in the process and move toward or away from each other, so as to realize the intermittent discharge of the raw lacquer paste in the feed hopper 3. Firstly, the discharge amount of the raw lacquer paste in the feed hopper 3 can be kept relatively consistent, and the three-roll grinder 1 will not be fed with too much raw lacquer paste, so as to ensure that the grinding operation can be carried out normally and continuously and the three-roll grinder 1 will not be shut down.

[0041] Considering that there are some impurities in the raw lacquer paste, the impurities will affect the quality of the raw lacquer paste. In order to remove the impurities, such as Figure 4 As shown in 6, a filter screen 6 is fixedly provided in the storage space of the feed hopper 3 by bolts, and is used to filter the unground raw lacquer slurry to ensure that impurities that can be filtered by the filter screen 6 will not pass through the filter screen 6, so as to improve the quality of the raw lacquer color slurry.

[0042] Furthermore, in order to prevent the filter 6 from being blocked, it also includes a toggle frame 1 7 and a toggle frame 2 8, the cross-sections of the toggle frame 1 7 and the toggle frame 2 8 are both U-shaped, and the toggle frame 1 7 and the toggle frame 2 8 are fitted on the upper surface of the filter 6, wherein the toggle frame 1 7 and the toggle frame 2 8 are fixedly connected to the connecting strip 1 46 and the connecting strip 2 47 respectively.

[0043] In this way, when baffle 1 41 and baffle 2 42 move toward or away from each other, the movement is transmitted through connecting strip 1 46 and connecting strip 2 47, and the shifting frame 1 7 and the shifting frame 2 8 move toward or away from each other synchronously to clean the surface of the filter 6 to ensure that the filter 6 will not be blocked.

[0044] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
