Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding equipment, and in particular relates to a manual hot-melt machine used for making plastic parts. Background Art

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material. They include products made from injection molding, vacuum forming and other processes using plastic as the raw material. Plastic is a type of synthetic polymer material with plasticity. Specifically, plastic is a material that uses natural or synthetic resin as the main component and various additives. It can be made into a certain shape under certain conditions of temperature and pressure and maintains the same shape at room temperature.

[0003] In the early stage of plastic product manufacturing, the raw materials need to be melted into a flowable colloid for subsequent injection molding, vacuum forming and other operations. Therefore, a raw material hot melt machine for plastic product production is needed. Some hot melt machines directly pour the raw materials into a heated stirring tank for stirring and melting. For example, Chinese patent application number CN201910691759.1 discloses an injection molding machine for plastic processing, including a chassis, a hot melt machine, a feed hopper, an extruder, an injection molding structure, and a drive box. The hot melt machine is horizontally installed on the left side of the upper end of the chassis and connected with bolts, the feed hopper is vertically installed on the right side of the upper end of the hot melt machine, the extruder is installed on the right side of the hot melt machine and are interconnected, the extruder is embedded in the left end of the injection molding structure, and the injection molding structure is horizontally installed on the upper end of the chassis and is arranged on the left side of the drive box.

[0004] As the applicant conducted further research, it was found that since the material in this technical solution is directly fed into the feed hopper, it is easy to cause blockage due to the different sizes of the material particles, resulting in the material being unable to enter the hot melt treatment stage below, affecting the subsequent extrusion of the hot melt plastic into the mold process. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] Manual hot melt machine for plastic parts production, including:

[0007] A tank body having a feed port and a heating wire arranged on the inner wall of the tank body;

[0008] A power motor is connected to the tank body, and an output end of the power motor is connected to a stirring mechanism extending into the tank body;

[0009] The feeding mechanism is arranged on the top of the tank body and is connected to the feeding port. The feeding mechanism includes a hopper, a rotating wheel connected to the inner wall of the hopper, a material guide plate inclined toward one side of the rotating wheel, and a crank for driving the rotating wheel to rotate. A plurality of grooves for accommodating materials are opened on the circumference of the rotating wheel.

[0010] Furthermore, a material blocking plate is connected below the material guide plate and is symmetrically arranged on the side of the rotating wheel.

[0011] Furthermore, the material blocking plate is in a U-shape.

[0012] Furthermore, the stirring mechanism includes at least one set of rotating shafts, and the rotating shafts are provided with paddles staggered in sequence along the length direction.

[0013] Furthermore, the rotating shafts are arranged in two groups, and the two groups of rotating shafts are connected to each other via a gear set.

[0014] Furthermore, the heating wires are distributed on the inner wall of the tank in a spiral shape from bottom to top.

[0015] Furthermore, a material blocking cover is provided at the opening of the hopper.

[0016] Furthermore, the height of the material blocking cover is not less than 20CM.

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

[0018] A rotating wheel is set in the hopper, and the handle is manually turned to rotate the wheel, so that the plastic granular material put into the hopper can be stirred. At the same time, part of the material can enter the groove and be brought to the bottom of the hopper as the wheel rotates, and then enters the tank body below to be melted. The setting of the rotating wheel can avoid the blockage of the hopper caused by excessive material input or large particles, which provides a guarantee for the subsequent hot melt extrusion mold process.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Among them, the drawings are only used for exemplary explanations, and they only show schematic diagrams rather than actual drawings, and cannot be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted, and the same or similar reference numerals in the drawings of the embodiments of the utility model correspond to the same or similar parts; in the description of the utility model, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer" and the like appear, the directions or positional relationships indicated are based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, so the terms describing the positional relationship in the drawings are only used for exemplary explanations, and cannot be understood as limitations on this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] like Figure 1 - Figure 4 As shown, the manual hot melt machine for making plastic parts of the utility model comprises a tank body 1, a power motor 2 and a feeding mechanism;

[0028] The tank body 1 has a feed inlet, a discharge port at the bottom thereof connected to the extrusion mechanism, and a heating wire 10 arranged on the inner wall of the tank body 1;

[0029] The power motor 2 is connected to the tank body 1, and the output end of the power motor 2 is connected to a stirring mechanism extending into the tank body 1;

[0030] The feeding mechanism is arranged at the top of the tank body 1 and is connected to the feeding port. The feeding mechanism includes a hopper 30, a rotating wheel 31 connected to the inner wall of the hopper 30, a material guide plate 32 inclined toward one side of the rotating wheel 31, and a crank 33 for driving the rotating wheel 31 to rotate. A plurality of grooves 310 for accommodating materials are opened on the circumference of the rotating wheel 31.

[0031] A rotating wheel 31 is provided in the hopper 30. By manually turning the crank 33 to rotate the rotating wheel 31, the plastic granular material put into the hopper 30 can be stirred. At the same time, part of the material can enter the groove 310 and be brought to the bottom of the hopper 30 as the rotating wheel 31 rotates, and enters the tank body 1 below to be melted. The arrangement of the rotating wheel 31 can avoid the situation where the hopper 30 is blocked due to excessive input of material or large particles, thereby providing a guarantee for the subsequent hot melt extrusion molding process.

[0032] A material blocking plate 34 is connected below the material guiding plate 32 and is symmetrically arranged on the side of the rotating wheel 31 .

[0033] Specifically, the baffle plate 34 is in a U-shape, with the opening of the baffle plate 34 facing the rotating wheel 31, and the inner walls on both sides of the baffle plate 34 shield the rotating wheel 31. The baffle plate 34 can be arranged in a symmetrical form. When the rotating wheel 31 rotates forward or reversely, when the material being carried away falls out of the groove 310, the baffle plate acts to block the material and make it fall vertically.

[0034] In order to enhance the uniformity of the hot melting of the material entering the tank body 1, a stirring mechanism is provided in the tank body 1. Through the action of the stirring mechanism, the semi-fluid material in the tank body 1 is stirred, especially the material with larger particles needs to be fully stirred. The stirring mechanism includes at least one set of rotating shafts 50, and the rotating shafts 50 are staggered with paddles 51 in sequence along the length direction. The arrangement of the paddles 51 can further enhance the stirring and melting effect, so that the materials at different liquid levels in the tank body 1 can be fully fused.

[0035] Specifically, the rotating shafts 50 are provided in two groups, and the two groups of rotating shafts 50 are connected to each other through a gear set 6. The gear set 6 can be in the form of a driving gear meshing with a driven gear.

[0036] In addition, the heating wires 10 are distributed on the inner wall of the tank body 1 in a spiral shape from bottom to top, so that the heating of the material is more uniform and more efficient.

[0037] In order to avoid material particles splashing onto the external ground when a large amount of material is put into the hopper 30, thereby causing material waste, a material blocking cover 7 can be provided at the opening of the hopper 30. The material blocking cover 7 can be made of elastic rubber material. When the material comes into contact with the material blocking cover 7, the material blocking cover 7 is deformed to reduce the distance the material is rebounded, thereby avoiding splashing to the outside of the hopper 30. Specifically, the height of the material blocking cover 7 can be set to 20CM or higher.

[0038] The above are only embodiments of the utility model. The common sense such as the known specific structures and characteristics in the scheme is not described in detail here. The ordinary technicians in the relevant field are aware of all the common technical knowledge in the technical field to which the utility model belongs before the application date or priority date, can obtain all the existing technologies in the field, and have the ability to apply the conventional experimental means before that date. The ordinary technicians in the relevant field can improve and implement the scheme in combination with their own abilities under the enlightenment given by this application. Some typical known structures or known methods should not become obstacles for the ordinary technicians in the relevant field to implement this application. It should be pointed out that for the technicians in this field, without departing from the structure of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
