Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and in particular relates to a feeding device for raw materials in the production of television casings. Background Technology

[0002] The television casing is a protective cover or shell on the outside of a television set. It is mainly used to protect the internal electronic components and to provide an aesthetically pleasing and practical product appearance. During production, it is often made by injection molding of raw ABS plastic after hot melting of the raw material using an extrusion molding machine.

[0003] Currently, when raw materials are fed into the extrusion molding machine through the hopper, heating components are installed on the outside of the pipe to preheat the raw materials. However, the heated area is on the outside, while the raw materials in the central area cannot be heated.

[0004] To address the aforementioned problems, this application proposes a raw material feeding device for television casing production. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding device for raw materials in the production of television casings, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a feeding device for raw materials in the production of television casings, including a hopper, a feed pipe and a top cover;

[0008] The feeding section is located at the center of the inside of the material tube, and its diameter is half the diameter of the material tube. A heating rod and an electric heating wire on the outside are provided between the outer ring of the feeding section and the inner wall of the material tube, so as to uniformly heat the plastic particles in the material tube by means of internal heating.

[0009] The U-shaped sleeve is a vulnerable component consisting of two long hollow tubes and one arc-shaped short hollow tube. It is fitted over the outside of the heating rod and heating wire to protect them from the intrusion of plastic particles.

[0010] Furthermore, the U-shaped sleeve has a side-opening tube structure, which can expand and shrink the opening for sealing.

[0011] Furthermore, the short hollow tube of the U-shaped sleeve is provided with plugs at both ends, which are connected to the bottom of the long hollow tube.

[0012] Furthermore, a rotating disk is provided at the center of the top cover, and a feeding part is installed through the support rod at its bottom. The upper end of the rotating disk is provided with a coaxial connecting rod connected to the rotating motor.

[0013] Furthermore, the upper end of the rotating disk is provided with a heating element that is electrically connected to a heating wire.

[0014] Furthermore, the bottom of the rotating disk is provided with threaded holes, four in a group, with the center point of each group coinciding with the axis of the long hollow tube of the U-shaped sleeve.

[0015] Furthermore, the upper end of the U-shaped sleeve is provided with an outwardly protruding adapter plate, and the U-shaped sleeve is fixed by screwing a bolt into the threaded hole.

[0016] Furthermore, the hopper is provided with fixed frames on both sides, and a rotating frame is rotatably installed on the upper end of the fixed frame on the right side. A rotating motor is provided above the rotating frame and is coaxial with the hopper. The left end of the rotating frame is fixedly connected to the fixed frame on the left side by bolts.

[0017] This utility model has the following beneficial effects:

[0018] This invention reduces the diameter of the feeding section and installs a U-shaped sleeve between the feeding section and the inner wall of the material pipe, so that the heat released by the heating rod and the heating wire can cover all the raw materials in the inner and outer areas, achieving the effect of uniform preheating of raw materials in different areas.

[0019] This invention separates the heating rod and heating wire into inner and outer layers, allowing the outer heating wire to be directly disassembled for cleaning or replacement when softened material adheres to the outer wall of the heating wire, affecting the heating rate, without affecting the normal use of the heating component, and also reducing maintenance costs.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figure 1-6 As shown, this utility model is a feeding device for raw materials in the production of television casings, including a hopper 1, a material pipe 2 and a top cover 4. Fixed frames 3 are provided on the left and right sides of the hopper 1. A rotating frame 5 is rotatably installed on the upper end of the right fixed frame 3. A rotating motor is provided above the rotating frame 5 and is coaxial with the hopper 1. The upper end of the left fixed frame 3 is connected and fixed to the movable end of the rotating frame 5 by bolts.

[0033] The feeding section 9, located at the center of the material tube 2, is a spiral blade mechanism with a diameter half that of the material tube 2. It forms an annular space between the outer edge and the inner wall of the material tube 2. The heating rod 11 and its outer heating wire 12 are installed through this annular space, so that the heating mechanism is built into the inside of the material tube 2. Based on this, the heat emitted covers all plastic particles in the central area and the outer ring area of ​​the material tube 2, and performs uniform preheating treatment.

[0034] The U-shaped sleeve 10 is a vulnerable component consisting of two long hollow tubes and one arc-shaped short hollow tube. It is sleeved on the outside of the heating rod 11 and the heating wire 12, replacing the heating element in contact with the plastic particles. This ensures the preheating performance of the plastic particles and allows for disassembly and replacement when the U-shaped sleeve 10 is absorbed by the plastic particles, resulting in a decrease in heat conduction performance, thereby reducing maintenance costs.

[0035] Among them, the U-shaped sleeve 10 is a side-opening tube structure. During installation, the opening is first enlarged to fit over the outside of the heating rod 11 and the heating wire 12, and then the opening is narrowed so that the two ends abut against each other to form a seal, so as to prevent plastic particles from entering the interior.

[0036] Preferably, the short hollow tube of the U-shaped sleeve 10 is installed in the same way as the long hollow tube, and both ends are provided with plugs connected to the bottom of the long hollow tube, which is suitable for the bottom connection structure of the two heating wires 12.

[0037] The top cover 4 has a rotating disk 6 at its center, which is spirally connected to the rotating shaft of the rotating motor above the rotating frame 5 via the connecting rod 14 at its upper end, and the feeding part 9 is installed via the coaxial support rod 8 below. Thus, by means of the rotational movement of the rotating frame 4, it can be rotated and unfolded to take out the lower feeding part 9.

[0038] Preferably, the upper end of the rotating disk 6 is provided with a heating part 7, which is electrically connected to the upper end of the heating wire 12.

[0039] The rotating disk 6 has threaded holes at its bottom, four in a group. The center point of each group coincides with the axis of the long hollow tube of the U-shaped sleeve 10. The upper end of the U-shaped sleeve 10 has an outwardly protruding adapter plate 13. The U-shaped sleeve 10 is fixed by screwing the threaded holes with bolts. Thus, the U-shaped sleeve 10 can be directly disassembled without disassembling the heating rod 11 and the heating wire 12.

[0040] Understandably, this invention can directly preheat the raw materials in the inner and outer regions, ensuring that the plastic particles are heated evenly while preventing them from interfering with the heating components, thus reducing the difficulty and cost of subsequent maintenance.

[0041] The specific operation process of this embodiment is as follows: First, the diameter of the feeding part 9 is reduced to half the diameter of the material tube 2. Then, the rotating disk 6 is lowered so that the heating rod 11 and the heating wire 12 are placed between the outer ring of the feeding part 9 and the inner wall of the material tube 2, so that the heat emitted by them can cover all the raw materials inside the material tube 2 and form a uniform preheating treatment for the raw materials in different areas. In addition, before the rotating disk 6 is lowered, the long hollow tube is sleeved on the outside of the two heating rods 11 and the heating wire 12 and closed to form a circular cover. Then, the short hollow tube is sleeved on the outside of the bottom connecting section of the two heating wires 12 and closed to form a circular cover. Then, the two ends of the short hollow tube are inserted into the bottom of the long hollow tube to form a transition. In this way, the two adjacent heating rods 11 and heating wires 12 can be covered inside to prevent plastic particles from contacting them. The U-shaped sleeve 10 is a vulnerable part and can be directly disassembled for cleaning or replacement after the heating rate decreases, reducing the difficulty of maintenance and the maintenance cost.
