Description

Technical Field

[0001] This utility model relates to the field of EPS toolbox production technology, specifically to a feeding box for molding automotive EPS toolboxes. Background Technology

[0002] EPS toolboxes are made of expanded polystyrene, also known as expandable polystyrene. It has advantages such as low relative density, low thermal conductivity, low water absorption, impact and vibration resistance, heat insulation, sound insulation, moisture resistance, vibration damping, and excellent dielectric properties. It is widely used as shockproof packaging material for mechanical equipment, instruments, household appliances, handicrafts and other easily damaged and valuable products, as well as packaging for fast food. Most toolboxes in automobiles are also made of expanded polystyrene.

[0003] The Chinese utility model patent with authorization announcement number "CN222346115U" is specifically "a molding production component for an automotive EPS toolbox", which includes: a support frame; a pressing box, which is fixedly installed on the support frame and has a stop door rotatably installed on the pressing box; a placement frame, which is fixedly installed on the top of the support frame and has a hydraulic cylinder on it, with a pressing plate fixedly installed on the output shaft of the hydraulic cylinder, the pressing plate being compatible with the pressing box; and a feeding box, which is set on the support frame.

[0004] While the aforementioned device facilitates the removal of the compressed EPS foam toolbox, making it easier for workers to process and operate the toolbox, thus improving efficiency, the design of the feeding box has shortcomings. EPS raw materials are usually granular, which easily accumulates and clumps inside the box. Furthermore, the EPS raw materials generate static electricity during handling, which causes them to adhere to the box walls when poured into the feeding box, resulting in poor material flowability and affecting the smoothness of subsequent material supply. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a feeding box for molding automotive EPS toolboxes, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a feeding box for molding an automotive EPS toolbox, comprising: a feeding hopper, a first cover plate rotatably connected to one side of the top of the feeding hopper, and a second cover plate rotatably connected to the other side of the top of the feeding hopper. An ion fan is fixedly connected to the middle of the top of both the first cover plate and the second cover plate. The ion fan includes a housing, a through hole in the middle of the housing, a dust cover fixedly connected to one end of the through hole, an electrode needle fixedly connected to one side of the dust cover, and a high-voltage generator fixedly connected inside the housing. The high-voltage generator is electrically connected to the electrode needle.

[0008] Furthermore, fixed seats are fixedly connected to the outer wall surfaces on both sides of the hopper, and a rotating hole is opened in the middle of the fixed seat.

[0009] Furthermore, a crossbar is fixedly connected to one end of both the first cover plate and the second cover plate, and the crossbar is rotatably connected inside the rotating hole.

[0010] Furthermore, a first gear is fixedly connected to both sides of the first cover plate, and a second gear is fixedly connected to both sides of the second cover plate, with the second gear meshing with the first gear.

[0011] Furthermore, connecting seats are fixedly connected to both sides of the first cover plate, and rotating shafts are fixedly connected to both sides of the discharge hopper, with limit blocks fixedly connected to the other end of the rotating shafts.

[0012] Furthermore, an electric telescopic rod is rotatably connected to the surface of the rotating shaft, and a connecting block is fixedly connected to the output end of the electric telescopic rod. The connecting block and the connecting seat are rotatably connected.

[0013] Furthermore, a bracket is fixedly connected to the middle of the through hole, a motor is fixedly connected to the middle of the bracket, a fan blade is connected to the output end of the motor via a spline, and a protective net is fixedly connected to the other end of the through hole.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0015] 1. By setting up the ion blower, a strong electric field is generated on the electrode needle by the high voltage generator inside the ion blower, which ionizes the air molecules and generates positive and negative ions. Then, the fan blows the ionized air into the discharge hopper to contact the surface of the EPS particles, and delivers positive and negative ions. The positive and negative ions combine with the electrostatic charge on the surface of the EPS particles to neutralize the static electricity, thereby effectively preventing the EPS particles from adsorbing on the box wall due to static electricity.

[0016] 2. Through the design of the motor and fan blades, the motor drives the fan blades to rotate at high speed during use. This not only delivers ionized air into the hopper but also ensures air circulation inside the hopper, thereby preventing EPS particles from clumping and accumulating, and thus maintaining good flowability of the EPS particle raw material.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments. Example 1:

[0027] Reference Figure 1-5This is the first embodiment of the present invention, which discloses a feeding box for molding an automotive EPS toolbox, including: a feeding hopper 1, a first cover plate 3 rotatably connected to one side of the top of the feeding hopper 1, and a second cover plate 4 rotatably connected to the other side of the top of the feeding hopper 1. An ion fan 8 is fixedly connected to the middle of the top of the first cover plate 3 and the second cover plate 4. The ion fan 8 includes a housing 801, a through hole 802 is opened in the middle of the housing 801, a dust cover 803 is fixedly connected to one end of the through hole 802, an electrode needle 804 is fixedly connected to one side of the dust cover 803, and a high voltage generator 809 is fixedly connected inside the housing 801. The high voltage generator 809 is electrically connected to the electrode needle 804.

[0028] With the ion fan 8 in use, the high-voltage generator 809 inside the ion fan 8 generates a strong electric field against the electrode needle 804, causing air molecules to ionize and generate positive and negative ions. Then, the fan blows the ionized air into the discharge hopper 1 to contact the surface of the EPS particles, transporting positive and negative ions. The positive and negative ions combine with the electrostatic charge on the surface of the EPS particles to neutralize the static electricity, thereby effectively preventing the EPS particles from adsorbing onto the box wall due to static electricity. Example 2:

[0029] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0030] A fixed seat 2 is fixedly connected to the outer wall surface on both sides of the hopper 1. A rotating hole 201 is opened in the middle of the fixed seat 2. A crossbar 202 is fixedly connected to one end of the first cover plate 3 and the second cover plate 4. The crossbar 202 is rotatably connected inside the rotating hole 201. A first gear 301 is fixedly connected to both sides of the first cover plate 3. A second gear 401 is fixedly connected to both sides of the second cover plate 4. The second gear 401 is meshed with the first gear 301.

[0031] Both sides of the first cover plate 3 are fixedly connected to connecting seats 5, both sides of the discharge hopper 1 are fixedly connected to rotating shafts 6, the other end of the rotating shaft 6 is fixedly connected to a limit block 601, the surface of the rotating shaft 6 is rotatably connected to an electric telescopic rod 7, the output end of the electric telescopic rod 7 is fixedly connected to a connecting block 701, and the connecting block 701 is rotatably connected to the connecting seat 5.

[0032] A bracket 805 is fixedly connected to the middle of the through hole 802, a motor 806 is fixedly connected to the middle of the bracket 805, a fan blade 807 is connected to the output end of the motor 806 via a spline, and a protective net 808 is fixedly connected to the other end of the through hole 802.

[0033] With the motor 806 and fan blade 807 in use, the motor 806 drives the fan blade 807 to rotate at high speed, which delivers ionized air into the discharge hopper 1 while ensuring air circulation inside the discharge hopper 1, thereby preventing EPS particles from clumping and accumulating, and thus maintaining good flowability of EPS particle raw materials.

[0034] The remaining structure is the same as that in Example 1.

[0035] The workflow of this utility model is as follows:

[0036] First, the bottom of the feeding hopper 1 is funnel-shaped. The outlet at the tip of the funnel is connected and fixed to the molding equipment. Then, the electric telescopic rod 7 is activated to open the first cover plate 3. During the opening process, the first cover plate 3 drives the second cover plate 4 to open synchronously through the interaction between the first gear 301 and the second gear 401. Then, the EPS granule raw material is poured into the inside of the feeding hopper 1. Then, the electric telescopic rod 7 is activated again to drive the first cover plate 3 and the second cover plate 4 to close. Through the setting of the first cover plate 3 and the second cover plate 4, it is ensured that the top of the feeding hopper 1 is in a closed state during the operation of the ion blower 8, preventing the EPS granules from flying around and overflowing from the top of the feeding hopper 1.

[0037] Secondly, the ion fan 8 is started. When the ion fan 8 is used, the high voltage generator 809 inside the ion fan 8 generates a strong electric field against the electrode needle 804, which ionizes the air molecules and generates positive and negative ions. Then, the fan blows the ionized air into the discharge hopper 1 to contact the surface of the EPS particles and transport positive and negative ions. The positive and negative ions combine with the electrostatic charge on the surface of the EPS particles to neutralize the static electricity, thereby effectively preventing the EPS particles from adsorbing on the box wall due to static electricity.

[0038] Finally, with the motor 806 and the fan blade 807 in use, the motor 806 drives the fan blade 807 to rotate at high speed, which delivers ionized air into the discharge hopper 1 while ensuring air circulation inside the discharge hopper 1, thereby preventing the EPS particles from clumping and accumulating, and thus maintaining the good flowability of the EPS particle raw material.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
