Description

Technical Field

[0001] The utility model relates to the field of hot-melt road markings, and in particular to a precise batching device for producing hot-melt road marking paint. Background Art

[0002] Thermoplastic road marking is a type of road marking. Road marking is divided into: thermoplastic road marking, room temperature cold paint road marking, color anti-skid road marking, oscillating anti-skid reflective road marking and preformed road marking. Thermoplastic road marking is the most widely used road marking in my country. It has short construction time, high wear resistance and low cost.

[0003] Since hot-melt road marking paint is made of a combination of multiple materials, the ratio between the multiple materials is particularly important. At present, most of the solid or powdered materials required for the preparation of hot-melt road markings are placed in a weighing cylinder for weighing to achieve accurate batching. However, in the actual application process, it is found that since the proportioning cylinder usually has a certain depth in order to accommodate more materials, when a certain material is weighed and the required proportion of the material is small, the material will be deposited at the bottom of the material cylinder. In this state, when there is too much material and it needs to be reduced, it is not easy for the operator to remove the excess material at the bottom of the material cylinder from the outside, which leads to relatively unchanged operation;

[0004] Therefore, we made improvements to this and proposed a precise dosing device for the production of hot-melt road marking paint. Utility Model Content

[0005] The utility model aims to provide a precise batching device for the production of hot-melt road marking paint, which solves the problem that the existing precise batching device for the production of hot-melt road marking paint is difficult to increase or decrease materials to achieve accurate weighing during use.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] A precise batching device for hot melt road marking paint production, comprising an electronic scale and a weighing platform arranged on the electronic scale, a supporting base is placed above the weighing platform, and further comprising:

[0008] A batching cylinder, which is arranged on and connected to the supporting base and is used for proportioning and weighing the ingredients for the production of hot-melt road marking paint;

[0009] A carrier plate is arranged inside the batching barrel and slidably cooperates with the inner wall thereof, and a batching space is provided above the carrier plate;

[0010] Among them, an elastic support structure connected to the carrying plate is also provided at the bottom of the batching barrel for elastically supporting the carrying plate.

[0011] As a preferred technical solution of the present application, the elastic support structure includes a support tube and a support arm, wherein the support tube is fixed in the dispensing tube and slidably cooperates with the support arm;

[0012] One end of the support arm is connected to a spring connected to the inner bottom wall of the support tube, and the other end of the support arm is fixed to a corresponding bearing plate above.

[0013] As a preferred technical solution of the present application, a conical material dividing plate is sleeved on the surface of the support cylinder, and a vibration motor is also installed inside the conical material dividing plate.

[0014] As a preferred technical solution of the present application, a discharge channel for discharging materials is formed at the outer edge of the dosing barrel corresponding to the conical distribution plate, and a collection box for collecting materials discharged from the discharge channel is sleeved on the outer side of the dosing barrel.

[0015] As a preferred technical solution of the present application, a support column for supporting the dispensing barrel is fixed in the discharge channel, and a limiting convex ring for limiting the collecting box is also fixed at the bottom of the collecting box.

[0016] As a preferred technical solution of the present application, the top of the dispensing barrel is also detachably connected with a lower hopper.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the scheme of this application:

[0019] 1. Through the support plate and elastic support structure, the support plate can slide in the batching barrel according to the proportion of the materials during the batching process. When the material is small, the weight of the support plate is small, so it will be located at the top of the batching barrel. Compared with the traditional batching device, the operator does not need to reach into the bottom of the batching barrel to take out the material, thus facilitating the accurate batching of the material;

[0020] 2. Through the setting of the conical powder plate and the lower hopper, when the material leaks out of the bottom of the batching barrel through the carrying plate, the vibrating motor can make the conical material distribution plate shake the material into the collection box for cleaning and removal, thus ensuring the accuracy of subsequent material weighing.

[0032] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0033] like Figure 1-Figure 6 As shown, a precise batching device for hot-melt road marking paint production includes an electronic scale 1 and a weighing platform 11 arranged on the electronic scale 1, a support base 12 is placed above the weighing platform 11, and also includes: a batching barrel 2, which is arranged on the support base 12 and connected thereto, and is used for weighing the batching ingredients for hot-melt road marking paint production;

[0034] The carrier plate 3 is arranged inside the dispensing barrel 2 and slidably cooperates with the inner wall thereof, and a dispensing space 31 is provided above the carrier plate 3. An elastic support structure 4 connected to the carrier plate 3 is also provided at the bottom of the dispensing barrel 2 for elastically supporting the carrier plate 3;

[0035] The elastic support structure 4 includes a support tube 41 and a support arm 42. The support tube 41 is fixed in the dispensing tube 2 and slidably cooperates with the support arm 42.

[0036] One end of the support arm 42 is connected to a spring 43 connected to the inner bottom wall of the support tube 41, and the other end of the support arm 42 is fixed to the corresponding upper bearing plate 3. The height of the bearing plate 3 moving downward when subjected to pressure can be achieved by replacing the spring 43 with different elastic coefficients. Specifically, it can be reasonably adjusted according to the proportion of various materials required in the actual production and preparation of hot-melt road marking paint, so that when more materials are added, the spring 43 can be compressed to meet the downward movement of the bearing plate 3 and increase the batching space 31, or when there is less material, the downward movement of the bearing plate 3 is small, which is convenient for adding and reducing materials;

[0037] like Figure 5 As shown, under the action of the spring 43, the carrier plate 3 is located above the inside of the dosing barrel 2 in the natural state. When weighing the non-fluid material required for the production of hot-melt road marking paint, the material will pass through the carrier plate 3 in the dosing space 31 above the carrier plate 3. As the material continues to increase, the weight on the carrier plate 3 will continue to increase and move downward to meet the continuous addition of the material. At this time, the electronic scale 1 can accurately form the weighing of the material ratio;

[0038] When weighing some materials with a small amount of mixing in the preparation of hot-melt road marking paint, the materials are placed in the mixing space 31, and the carrier plate 3 will not move down a large height distance, so it is convenient for operators to add materials on the carrier plate 3 outside the mixing barrel 2, thereby facilitating the mixing ratio use of daily hot-melt road marking paint production and preparation;

[0039] As a further optimization of this embodiment: a conical material dividing plate 5 is sleeved on the surface of the support cylinder 41, and a vibration motor 51 is also installed inside the conical material dividing plate 5;

[0040] During the long batching process, some materials may fall into the inside of the batching barrel 2 through the gap between the carrier plate 3 and the batching barrel 2. At this time, the conical dividing plate 5 can centrally drain the falling materials and drive the vibration motor 51 to vibrate, thereby further promoting the concentration of the materials.

[0041] A discharge channel 52 for discharging materials is formed at the outer edge of the dispensing barrel 2 corresponding to the conical dispensing plate 5, and a collection box 53 for collecting materials discharged from the discharge channel 52 is sleeved on the outer side of the dispensing barrel 2;

[0042] After the material leaking out of the bottom of the batching barrel 2 is shaken by the vibration motor 51, the material will be discharged into the collection box 53 through the discharge channel 52. By taking out the collection box 53, the excess material can be cleaned up, thereby ensuring that the subsequent material weighing will not be affected, and further improving the accuracy of the proportion during the production and preparation of the hot-melt road marking paint;

[0043] A support column 54 for supporting the dispensing barrel 2 is fixed in the discharge channel 52, and a limiting convex ring 55 for limiting the collecting box 53 is also fixed at the bottom of the collecting box 53;

[0044] The design of the limiting convex ring 55 can form a support for the collecting box 53, so that the collecting box 53 can form a limiting effect at the position corresponding to the discharge channel 52, thereby meeting the continuous collection of materials;

[0045] As a further optimization of this embodiment: the top of the batching barrel 2 can be detachably connected with a lower hopper 6;

[0046] like Figure 2 As shown, the lower hopper 6 can be disassembled at the top of the dispensing barrel 2, so that it will not form a movement obstacle with the collecting box 53 during the removal process, and it is convenient to weigh and add materials when mixing the hot melt road marking paint.
