Technical Field

[0001] The utility model belongs to the technical field of hot melt adhesive production, and particularly relates to a filling device for hot melt adhesive. Background Art

[0002] Hot melt adhesive is a plastic adhesive. Within a certain temperature range, its physical state changes with the change of temperature, while its chemical properties remain unchanged. It is non-toxic and odorless, belonging to an environment-friendly chemical product. Since the product itself is solid, it is also convenient for packaging, transportation, storage, solvent-free, pollution-free and non-toxic.

[0003] During the production and preparation process of hot melt adhesive, a filling device is needed to fill the processed hot melt adhesive solid particles for convenient packaging and subsequent sales. However, through investigation and research, it is found that the common hot melt adhesive filling devices on the market are not convenient for quantitative discharging, which easily leads to large errors in the filling amount and is not convenient for unifying the filling specifications. Moreover, when the solid particle-shaped hot melt adhesive is discharged, it is easy to be blocked due to mutual extrusion, affecting the filling. Therefore, it is urgent to improve the existing hot melt adhesive filling device and provide a filling device for hot melt adhesive that can discharge quantitatively. Summary of the Utility Model

An anti-sticking stirring component is arranged inside the collection tank, and the driving motor is in transmission connection with the anti-sticking stirring component. A quantitative filling component is installed in the middle of the bottom of the collection tank. Two brackets are symmetrically and fixedly arranged on the outer walls of the left and right sides of the bottom of the collection tank. The bottom ends of the brackets are respectively fixed with two connecting plates. Two guiding grooves are symmetrically arranged in the front and back in the connecting plates.

A toothed ring is arranged outside the gear, and the toothed ring is fixedly installed on the inner wall of the top of the collection tank.

[0007] Preferably, the central axes of the stirring shaft, the gear ring, and the collection tank coincide with each other. Both gears are meshed with the gear ring, and the diameter of the gears is smaller than that of the gear ring.

[0008] Preferably, the quantitative filling assembly includes a discharge pipe, a feed trough, a feeding hopper, a cut-off plate, and a fixing rod. The discharge pipe is slidably lifted in the discharge pipe provided at the bottom of the collection tank. A plurality of feed troughs are annularly provided on the outer wall of the top end of the discharge pipe. A feeding hopper is fixedly connected to the bottom of the discharge pipe. Two cut-off plates for controlling the on-off of the discharge are provided between the discharge pipe and the feeding hopper.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] In the solution of the present utility model, the discharge pipe is pushed up by the electric push rod. At this time, the fixing rod moves up along the vertical section of the guiding groove, so that the two cut-off plates can be in a closed state. And through a plurality of feed troughs, it is convenient for the hot melt adhesive particles in the collection tank to automatically slide into the discharge pipe. Then, the electric push rod is used to control the discharge pipe to move down. The feed troughs can be closed due to being blocked. Subsequently, when the discharge pipe continues to move down, the inclined section of the guiding groove can be used to push the fixing rod and the cut-off plate to slide open, so that the hot melt adhesive particles in the discharge pipe can be added to the pre-prepared filling container through the feeding hopper.

[0030] As a preferred embodiment, on the basis of the above structure, further, the quantitative filling assembly 5 includes a material discharging pipe 51, a feeding groove 52, a feeding hopper 53 and a cutoff plate 54. The material discharging pipe 51 is slidably and liftably disposed in a discharge pipe provided at the bottom of the collecting tank 1.

[0036] The working principle of the present utility model is as follows:

[0037] During use, first, the hot melt adhesive solid particles to be sub-packaged are added to the collecting tank 1 through the feeding pipe 2. When filling, first start the electric push rod 9 to control the material discharging pipe 51 to rise as shown in Figure 3 At this time, the fixing rod 55 moves upward along the vertical section of the guiding groove 8. Therefore, the two cutoff plates 54 are in a static closed state. When the material discharging pipe 51 rises to make the feeding groove 52 unblocked, at this time, the hot melt adhesive solid particles can automatically enter the material discharging pipe 51 through the plurality of feeding grooves 52 formed in a ring shape;

[0038] Place the prepared filling container directly below the feeding hopper 53, and then control the discharge pipe 51 to move downward through the electric push rod 9. The feeding chute 52 can be closed due to being blocked. Subsequently, when the discharge pipe 51 continues to move downward, the inclined section of the guiding groove 8 can be used to push the fixed rod 55 and the cut-off plate 54 to slide open to be in the state as shown in Figure 6 the figure, and the hot melt adhesive particles in the discharge pipe 51 can be added to the filling container below through the feeding hopper 53. Since the internal volume of the discharge pipe 51 is constant, it is convenient to realize the quantitative extraction and filling of the hot melt adhesive particles, avoid large errors between the filling amounts, and facilitate the unification of the filling specifications;

[0039] Meanwhile, during the filling process, the driving motor 3 can also be started to control the T-shaped rod 41 to drive the left and right stirring shafts 42 to rotate synchronously around the central line of the collection tank 1. And during this process, by using the meshing gears 43 and the gear ring 44, the two stirring shafts 42 can rotate at high speed, which is convenient for dispersing and preventing adhesion of the hot melt adhesive solid particles in the collection tank 1. Thus, when the discharge pipe 51 rises, the hot melt adhesive solid particles can enter the discharge pipe 51 more smoothly, avoiding the situation of discharge blockage and facilitating the stable and smooth progress of the filling work.
