Description

Technical Field

[0001] This utility model belongs to the field of ABS plastic processing technology, and more specifically, it relates to a high-efficiency and energy-saving heating device in ABS plastic processing. Background Technology

[0002] ABS plastic is a high-performance engineering plastic with excellent overall properties, including toughness, hardness, and rigidity. It is widely used in numerous fields such as automobiles, home appliances, and electronics. During ABS plastic processing, such as injection molding, extrusion molding, and thermoforming, the plastic raw material typically needs to be heated to a specific processing temperature to achieve good flowability and molding results.

[0003] Application number CN202220395489.7 discloses a heating device for plastic processing, including a base plate. Two support seats are fixedly connected to the upper surface of the base plate. A heat insulation cylinder is fixedly connected to the upper surface of each support seat. A cylindrical shell is movably connected inside the heat insulation cylinder, and a heating shell is disposed inside the cylindrical shell. An oil inlet pipe is sealed and inserted into the upper surface of the cylindrical shell, passing through the heat insulation cylinder. Two support frames are fixedly connected to the upper surface of the base plate, and a common support rod is fixedly connected between the support frames. Two bearings are fixedly connected to one side of the circumference of the support rod. Connecting cylinders are fixedly connected to the outer walls of both sides of the heating shell. The outer circumference of the bearings is fixed to the inner circumference of the connecting cylinder, and a driven gear is fixedly connected to one side of the circumference of one of the connecting cylinders. This invention ensures uniform heating of the plastic, reduces processing time, saves time, and ensures efficient plastic processing.

[0004] Based on the above patent search and understanding of the application of existing ABS plastic processing heating: traditional heating devices have difficulty ensuring the uniformity of plastic raw material heating, resulting in some raw materials being underheated or overheated, affecting the quality and performance of the final product. On the other hand, the energy utilization efficiency of existing devices is low, often requiring a large amount of energy to maintain the heating process, which not only increases production costs but also does not conform to the current development trend of energy conservation and environmental protection. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a high-efficiency and energy-saving heating device for ABS plastic processing. This solves the problem that existing traditional heating devices cannot guarantee the uniformity of heating plastic raw materials, resulting in some raw materials being underheated or overheated, which affects the quality and performance of the final product. It also addresses the issue that existing devices have low energy utilization efficiency and often require a large amount of energy to maintain the heating process.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A high-efficiency and energy-saving heating device for ABS plastic processing includes a wrapping cylinder; a ring-shaped partition is fixedly installed at the front and rear ends of the middle of the wrapping cylinder, and a padding frame is symmetrically fixedly installed at the front and rear ends of the wrapping cylinder. The inner sides of the two partitions are rotatably connected to the front and rear ends of the heating tank. The heating tank is located in the middle of the wrapping cylinder. A conveying pipe is connected to the middle of the middle of the wrapping cylinder. The conveying pipe has a spiral design and passes through the middle of the two partitions and the two padding frames.

[0008] According to one embodiment of the present invention, a motor is fixedly installed above the front of the padding shelf at the front end of the packaging tube, the motor shaft passes through the interior of the padding shelf at the front end of the packaging tube, and a drive gear is fixedly installed at the rear end of the motor shaft.

[0009] According to one embodiment of the present invention, a toothed ring is provided at the front end of the heating tank. The toothed ring is located at the front end of the inner part of the wrapping cylinder, and the inner side of the toothed ring meshes with the upper end of the drive gear.

[0010] According to one embodiment of the present invention, an auxiliary gear is fixedly installed at the middle front end of the conveying pipe. The auxiliary gear meshes with the lower end of the driving gear. The gear ring is designed with the driving gear and the auxiliary gear on the same plane.

[0011] According to one embodiment of the present invention, a mounting frame is symmetrically fixedly connected to the front and rear ends of the packaging tube, and the bottom of the mounting frame is lower than the bottom of the packaging tube.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The heating tank and the conveying pipe rotate in opposite directions. The rotation of the heating tank can fully cover the material position in the middle of the conveying pipe. During the process of conveying material by the rotating conveying pipe, the heating tank heats the material from all directions to ensure that the ABS plastic material inside the conveying pipe is heated evenly. This effectively avoids the situation of insufficient or excessive heating of some materials, thereby improving the quality and performance stability of the final product, reducing product defects, and increasing the product qualification rate.

[0014] This device can drive the heating tank and the conveying pipe to rotate using only a single motor. Compared with the traditional multi-motor drive method, it greatly reduces energy consumption. At the same time, the heating tank is located inside the wrapping cylinder. The gap between the heating tank and the wrapping cylinder, as well as the gap between the partition and the padding frame, can effectively reduce the heat dissipation of the heating tank to the outside, avoid the additional heating power consumption caused by the cooling of the heating tank, reduce the overall energy consumption, meet the requirements of energy conservation and environmental protection, and reduce production costs.

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a high-efficiency and energy-saving heating device for ABS plastic processing, including a wrapping cylinder 1; a ring-shaped partition 101 is fixedly installed at the front and rear ends of the middle of the wrapping cylinder 1, and a padding frame 102 is symmetrically fixedly installed at the front and rear ends of the wrapping cylinder 1. The inner sides of the two partitions 101 are rotatably connected to the front and rear ends of the heating tank 106. The heating tank 106 is located in the middle of the middle of the wrapping cylinder 1. A conveying pipe 103 is passed through the middle of the middle of the wrapping cylinder 1. The conveying pipe 103 has a spiral design inside and passes through the middle of the two partitions 101 and the two padding frames 102.

[0027] Among them, a motor 104 is fixedly installed at the upper front position of the padding rack 102 at the front end of the packaging cylinder 1. The rotating shaft of the motor 104 passes through the interior of the padding rack 102 at the front end of the packaging cylinder 1. A drive gear 105 is fixedly installed at the rear end of the rotating shaft of the motor 104. A gear ring 107 is provided at the front end of the heating tank 106. The gear ring 107 is located at the middle front end of the interior of the packaging cylinder 1. The inner side of the gear ring 107 meshes with the upper end of the drive gear 105. An auxiliary gear 131 is fixedly installed at the middle front end of the conveying pipe 103. The auxiliary gear 131 meshes with the lower end of the drive gear 105. The gear ring 107, the drive gear 105, and the auxiliary gear 131 are designed on the same plane. A mounting frame 2 is symmetrically fixedly connected at both ends of the packaging cylinder 1. The bottom of the mounting frame 2 is lower than the bottom of the packaging cylinder 1.

[0028] When using:

[0029] The ABS plastic raw material to be processed is added from the front end of the feed pipe 103. Since the feed pipe 103 has a spiral design inside, this structure can play the role of conveying materials when the device is running. When adding materials, attention should be paid to controlling the amount of materials added to ensure the continuity and stability of processing.

[0030] When the power supply to the motor 104 is turned on, the motor 104 starts to run. Its shaft drives the drive gear 105 fixedly installed at the rear end to rotate. The drive gear 105 meshes with the gear ring 107 set at the front end of the heating tank 106, thereby driving the heating tank 106 to rotate around its own axis. At the same time, the drive gear 105 also meshes with the auxiliary gear 131 at the front end of the conveying pipe 103, causing the conveying pipe 103 to rotate accordingly. The ABS plastic material inside the conveying pipe 103 completes the heating effect when it passes through the internal space of the heating tank 106.

[0031] When the conveying pipe 103 rotates, the heating tank 106 rotates in the opposite direction to the conveying pipe 103. The rotation of the heating tank 106 can fully cover the middle of the conveying pipe 103, ensuring that the material inside the conveying pipe 103 is heated evenly. Since a single motor 104 can drive the heating tank 106 and the conveying pipe 103 to rotate, energy consumption is saved.

[0032] Furthermore, the heating tank 106 is located inside the wrapping cylinder 1. The gap between the heating tank 106 and the wrapping cylinder 1 prevents the heating tank 106 from cooling down and causing additional heating power consumption, thus achieving an energy-saving effect. The gap formed between the partition 101 and the padding shelf 102 further prevents the heating tank 106 from being affected by external temperature interference and causing a temperature drop.

[0033] Although this application has been described with reference to the foregoing embodiments, those skilled in the art will understand that various changes can be made without departing from the spirit and scope of this application as defined by the appended claims. While this specification contains details of many specific implementations, these should not be construed as limiting the scope of the claims, but rather as descriptions of features specific to particular embodiments. The scope of this application is defined by the appended claims and their equivalents, and is not limited to the embodiments described above.
