Description

Technical Field

[0001] This utility model relates to a PTC auxiliary electric heater for producing aluminum grinding equipment. Background Technology

[0002] PTC (Positive Temperature Coefficient) auxiliary electric heaters are widely used in household appliances such as air conditioners and fan heaters due to their low starting current, safety, reliability, and good temperature control. The aluminum heat sink / casing of PTC heaters not only requires high dimensional accuracy, but the surface quality directly affects the subsequent coating, brazing, and bonding with the PTC ceramic sheet.

[0003] Traditional through-feed grinders have fixed upper and lower brush wheels, which can only adapt to aluminum materials of a single thickness. Once the product model is changed, the brush wheels need to be completely disassembled or the gaskets need to be replaced, resulting in long downtime. The "brush deflection" phenomenon caused by brush wheel wear cannot be compensated online, resulting in a gradual reduction in the amount of grinding, and the appearance of "uneven surfaces" or local missed areas.

[0004] Therefore, a PTC-assisted electric heater is proposed for producing aluminum grinding equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a PTC auxiliary electric heater for producing aluminum grinding equipment, in order to solve the problem mentioned in the background art that traditional through-type grinding machines can only adapt to aluminum materials of a single thickness specification. Once the product model is changed, the brush wheel or the gasket needs to be completely disassembled or replaced, resulting in long downtime.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a grinding equipment for aluminum production using a PTC auxiliary electric heater, comprising a grinding box, wherein the grinding box is provided with an inlet and an outlet at both ends for the aluminum material to enter and exit the PTC auxiliary electric heater during production. Inside the grinding box, grinding brush wheels are arranged on the upper and lower sides of the aluminum material. Two sets of grinding brush wheels are equipped with drive motors on their back sides. The two sets of drive motors are connected to the grinding box through a rotation adjustment component. The grinding box adjusts the position of the grinding brush wheel by rotating the adjustment assembly.

[0007] Preferably, the rotation adjustment assembly includes a support base plate disposed on the back side of the grinding box, the two ends of the support base plate being connected to the grinding brush wheel, and the middle part of the support base plate being connected to the grinding box via a rotating seat.

[0008] Preferably, a handwheel is provided on the back side of the grinding box, a lead screw is connected to one side of the handwheel, an adjusting rod is provided at the tail end of the lead screw, and a limit baffle is provided at the tail end of the adjusting rod.

[0009] Preferably, a connecting rod is provided at the lower part of the supporting base plate, and the tail end of the connecting rod is sleeved on the outer periphery of the adjusting rod through an adjusting hole.

[0010] Preferably, the inner diameter of the adjusting hole is larger than the outer diameter of the adjusting rod, so that the connecting rod can rotate relative to the adjusting rod through the adjusting hole.

[0011] Preferably, the grinding box is provided with a threaded bushing on the side wall of the handwheel, and the threaded bushing cooperates with the lead screw so that the lead screw moves linearly through the threaded bushing to connect the adjusting rod.

[0012] Preferably, the support base plate is connected to the grinding box around its perimeter by clamping bolts, and the inner wall of the grinding box is provided with an arc-shaped waist hole that mates with the clamping bolts, so that the clamping bolts connecting the support base plate can move within the grinding box through the arc-shaped waist hole.

[0013] Preferably, the inner wall of the grinding box has a through groove for the shaft to slide at the pivot of the two sets of grinding brushes, and the inner diameter of the through groove is larger than the outer diameter of the shaft, so that the shaft can rotate in the grinding box by connecting the grinding brushes through the through groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention allows for flexible adjustment of the grinding brush wheel position via a rotating adjustment component, adapting to various aluminum thicknesses. During the grinding process of aluminum profiles, adjustments can be made online, significantly reducing downtime and eliminating the need for frequent disassembly and reassembly of the brush wheel or replacement of shims, thereby improving production efficiency.

[0015] The arc-shaped groove design allows the brush wheel shaft to adjust and compensate according to the degree of wear, effectively avoiding the "blade slippage" phenomenon, ensuring uniform grinding amount, eliminating "uneven grinding surfaces" and local missed grinding problems, and guaranteeing the surface quality of aluminum materials.

[0016] The handwheel, in conjunction with the lead screw and support base plate, allows for easy adjustment of the brush wheel position without complex disassembly, reducing the difficulty and cost of equipment maintenance.

[0017] The support base plate is connected to the arc-shaped waist hole by clamping bolts, which not only ensures the firmness of the brush wheel installation, but also facilitates fine-tuning of the position and enhances the overall stability of the equipment. Attached Figure Description

Detailed Implementation

[0020] To address the issue that traditional through-feed polishing machines can only handle aluminum materials of a single thickness, requiring extensive disassembly and reassembly of the brush wheels or replacement of gaskets when changing product models, resulting in long downtime, this invention provides a PTC auxiliary electric heater-based aluminum polishing equipment. The technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] Please see Figure 1-4 This utility model provides a grinding device for aluminum materials produced by a PTC auxiliary electric heater, including a grinding box 1. The grinding box 1 has an inlet 2 and an outlet 3 at both ends for the aluminum materials to enter and exit the PTC auxiliary electric heater. Inside the grinding box 1, grinding brush wheels 4 are arranged on the upper and lower sides of the aluminum material. Two sets of grinding brush wheels 4 are equipped with drive motors 5 on their back sides. The two sets of drive motors 5 are connected to the grinding box 1 through a rotation adjustment component 6. The rotation adjustment assembly 6 includes a support base plate 61 disposed on the back side of the grinding box 1. Both ends of the support base plate 61 are connected to the grinding brush wheel 4, and the middle part of the support base plate 61 is connected to the grinding box 1 through a rotating seat 63.

[0022] A handwheel 64 is provided on the back side of the grinding box 1. A lead screw 65 is connected to one side of the handwheel 64. An adjusting rod 66 is provided at the tail end of the lead screw 65, and a limit baffle 67 is provided at the tail end of the adjusting rod 66. A connecting rod 68 is provided at the lower part of the support base plate 61. The tail end of the connecting rod 68 is sleeved on the outer periphery of the adjusting rod 66 through an adjusting hole 69. The inner diameter of the adjusting hole 69 is larger than the outer diameter of the adjusting rod 66, so that the connecting rod 68 can rotate relative to the adjusting rod 66 through the adjusting hole 69. The support base plate 61 is connected to the grinding box 1 around its perimeter by clamping bolts 62. An arc-shaped waist hole 11 is opened on the inner wall of the grinding box 1 to cooperate with the clamping bolts 62, so that the clamping bolts 62 connected to the support base plate 61 can move within the grinding box 1 through the arc-shaped waist hole 11. The grinding box 1 is provided with a threaded bushing 610 on the side wall of the handwheel 64, and the threaded bushing 610 and the lead screw 65 cooperate with each other so that the lead screw 65 can move linearly through the adjusting rod 66 connected by the threaded bushing 610.

[0023] The grinding box 1 adjusts the position of the grinding brush wheel 4 by rotating the adjustment component 6.

[0024] The inner wall of the grinding box 1 is provided with a through groove 12 for the shaft to slide at the pivot of the two sets of grinding brush wheels 4. The inner diameter of the through groove 12 is larger than the outer diameter of the shaft, so that the shaft can rotate in the grinding box 1 by connecting the grinding brush wheels 4 through the through groove 12.

[0025] The working principle of the PTC auxiliary electric heater aluminum grinding equipment provided by this utility model is as follows: the aluminum material to be ground is slowly fed into the grinding box through the inlet, so that the aluminum material is stably placed between the upper and lower sets of grinding brushes.

[0026] Start the drive motor to make the upper and lower grinding brush wheels rotate at high speed to grind the surface of the aluminum material. At this time, the aluminum material moves forward along the inside of the grinding box under the action of friction of the brush wheels.

[0027] During the polishing process, if the aluminum material has uneven thickness or slight warping, the handwheel is turned to drive the lead screw to make linear motion. The lead screw abuts against the side of the connecting rod and pushes the support base plate to rotate through the rotating seat until the wall of the connecting rod through the hole and the adjusting rod abut against each other, thereby driving the support base plate to rotate and adjust the height of the polishing brush wheel to adapt to changes in the thickness of the aluminum material or to compensate for the wear of the brush wheel, so as to closely fit the surface of the aluminum material and ensure that the polishing effect is uniform.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
