Description

Technical Field

[0001] This utility model relates to the field of talc powder processing technology, specifically to an automatic feeding structure for a talc powder grinding device. Background Technology

[0002] Talc powder is an industrial product. Its main material is talc, a magnesium silicate mineral. After being crushed, it is treated with hydrochloric acid, washed with water, and dried. It is commonly used as a filler in plastic and paper products, a rubber filler and an anti-sticking agent for rubber products, and in high-grade paints and coatings. When grinding talc powder, a feeding device is required to transport the talc particles to the grinding device.

[0003] A search revealed a Chinese patent for an automatic feeding structure for a talc powder grinding device, publication number CN222724493U. The structure includes a housing, a fixed frame fixedly connected to the left side of the top of the housing, a dual-axis motor fixedly connected to the top of the fixed frame, and a take-up roller fixedly connected to the output end of the dual-axis motor.

[0004] The aforementioned device, consisting of a fixed frame, dual-axis motor, winding roller, fabric belt, fixing block, frame, cutting mesh, extrusion plate, and crushing teeth, not only facilitates automatic feeding but also facilitates pre-crushing of materials. By setting up a servo motor, grinding roller, and grinding disc, it facilitates grinding of materials.

[0005] However, its lifting structure is relatively simple. Due to the different particle size and moisture content of talc ore, it is easy to cause talc particles to stick to the extrusion plate and cause blockage by simply crushing it through extrusion. In addition, after feeding, the feed frame needs to be lowered again, and this step needs to be repeated for subsequent feeding. The waiting time for the up and down process is long, the feeding continuity is poor, and it is easy to cause the grinding device to run idle. Utility Model Content

[0006] The purpose of this invention is to provide an automatic feeding structure for a talc powder grinding device, which can effectively solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0016] Compared with the prior art, the beneficial effects of this utility model are:

Dry hot air can be blown into the feeding cylinder through the jet pipe to keep the transported talc particles in a dry state, reduce the probability of them being damp and clumping, thereby reducing the probability of blockage. Furthermore, the continuous spraying of hot air can make the talc particles more loose, which can improve the smoothness of conveying.

[0018] By setting up a crushing cutter disc, mica electric heating plate, feeding box, feeding cylinder, and lifting auger to work together, the feeding process does not require a long waiting time, which facilitates continuous feeding and ensures the continuity of talc particle grinding. This avoids the grinding device running idle due to interruption of feeding, thereby improving production efficiency.

[0024] 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.

[0025] Example 1

[0026] Combination Figures 1-4 An automatic feeding structure for a talc powder grinding device includes a support base 1, a feeding component 2 is provided at the top of the support base 1, the feeding component 2 has a feeding cylinder 3 and a discharge box 4, the feeding cylinder 3 is fixedly installed at the top of the support base 1, and the discharge box 4 is fixedly installed at the lower feed inlet of the feeding cylinder 3.

[0027] See Figure 2 and Figure 3Furthermore, a discharge port 5 is provided at the top of the discharge box 4 on one side. The interior of the discharge box 4 is provided with a guide ramp that is compatible with the feed inlet of the feeding cylinder 3. A lifting auger 11 is rotatably installed inside the feeding cylinder 3 via a rotating shaft. A feeding motor 13 is installed at the top of the feeding cylinder 3 via a mounting box 12. The drive shaft of the feeding motor 13 passes through the upper and lower ends of the mounting box 12 and is fixedly connected to the top of the rotating shaft of the lifting auger 11. The side of the mounting box 12 away from the discharge box 4 A feeding box 14 is connected at the upper position. A feeding pipe 16 is installed at the bottom of the feeding box 14 through a telescopic tube. An electric telescopic rod 15 is installed at the bottom of the feeding box 14 away from the feeding cylinder 3. The push rod of the electric telescopic rod 15 is connected to the top of the feeding pipe 16 through a connecting piece. Several air jet pipes 18 are connected through the rear end of the feeding cylinder 3. An exhaust pipe is set at the lower rear end of the feeding cylinder 3. A leak-proof baffle is set at the connection between the air jet pipes 18 and the exhaust pipe and the feeding motor 13.

[0028] Specifically, by connecting the discharge port of the external talc particle storage cylinder to the discharge port 5, the talc particles to be ground can be transported to the discharge box 4. Since the discharge box 4 is equipped with a guide ramp, the incoming raw material can be guided into the feeding cylinder 3. At this time, by starting the feeding motor 13, the lifting auger 11 can be driven to rotate, thereby lifting the material entering the feeding cylinder 3 until the material reaches the inlet of the discharge box 14. The material will slide out from the electric telescopic rod 15 through the guide of the discharge box 14, thus completing the feeding process. Since the feeding cylinder 3 is connected to several air jet pipes 18, and the outer ring of the feeding cylinder 3 is equipped with an exhaust port at the lower position, the air jet pipes 18 are connected to the external hot air pipes so that dry hot air can be continuously delivered to the feeding cylinder 3 and sprayed out to dry the talc particles in the feeding cylinder 3, preventing them from being too wet and sticky. At the same time, the hot air continuously blows the material to agitate it, making the talc particles being lifted looser, thereby improving the smoothness of feeding.

[0029] Example 2

[0030] See Figure 2 and Figure 4Furthermore, based on Embodiment 1, a crushing disc 6 is rotatably mounted inside the feeding box 4 and below the feeding port 5 via a rotating rod. A crushing motor 7 is mounted at the front end of the feeding box 4, and the drive shaft of the crushing motor 7 is fixedly connected to the rotating shaft of the crushing disc 6. An installation groove is provided inside the guide slope, and a mica electric heating element 10 is installed in the installation groove. A vibration motor 8 is installed on one side of the feeding box 4. The inner walls of the feeding box 4, the feeding port 5, the feeding cylinder 3, and the outer wall of the lifting auger 11 are all coated with a polytetrafluoroethylene layer. The outer ring of the lifting auger 11 is in contact with the inner wall of the feeding cylinder 3. A transparent observation window 17 is provided at the center of the front end of the feeding cylinder 3. A guide block 9 that is compatible with the crushing disc 6 is provided inside the feeding box 4. The center points of the crushing disc 6 and the feeding port 5 are on the same vertical line, and the crushing disc 6 does not contact the guide block 9 and the feeding port 5.

[0031] Specifically, when the talc particles to be ground enter from the discharge port 5, the crushing motor 7 can be started. The drive shaft of the crushing motor 7 rotates, which drives the crushing cutter disc 6 to rotate continuously, so as to pre-crush the incoming talc particles. At the same time, during the feeding process, the mica electric heating plate 10 can be controlled to heat up, so as to heat and dry the talc particles falling on the guide slope. At the same time, the vibration motor 8 can be started to drive the discharge box 4 to vibrate, so as to further reduce the probability of talc particles accumulating and clogging at the discharge port 5 and improve the feeding effect. At the same time, during feeding, the feeding situation in the feeding cylinder 3 can be observed through the transparent observation window 17.

[0032] In actual operation, bearings are installed at each drive shaft, which will not be described in detail here. When feeding, the feeding cylinder 3 can be fixed to a suitable position by passing external anchor bolts through the fixing holes on the support base 1. Then, the discharge port of the external talc particle storage cylinder can be connected to the discharge port 5, and the talc particles to be ground can be transported to the discharge box 4. Since the discharge box 4 is equipped with a guide ramp, the incoming raw material can be guided into the feeding cylinder 3. At this time, by starting the feeding motor 13, the lifting auger 11 can be driven to rotate, thereby lifting the material entering the feeding cylinder 3 until the material reaches the feed inlet of the discharge box 14. The material will slide out from the electric telescopic rod 15 through the guide of the discharge box 14, thus completing the feeding process.

[0033] Because the feeding cylinder 3 is connected to several jet pipes 18, and an exhaust port is provided at the lower position of the outer ring of the feeding cylinder 3, the jet pipes 18 are connected to the external hot air pipes so that dry hot air can be continuously delivered to the feeding cylinder 3 and sprayed out to dry the talc particles in the feeding cylinder 3 and prevent them from being too wet and sticking together. At the same time, the hot air continuously blows the material to agitate it, which can make the talc particles in the lifting process more loose, so as to improve the smoothness of feeding.

[0034] When the talc particles to be ground enter from the feed port 5, the crushing motor 7 can be started. The drive shaft of the crushing motor 7 rotates, which can drive the crushing cutter disc 6 to rotate continuously so as to pre-crush the incoming talc particles. At the same time, during the feeding process, the mica electric heating plate 10 can be controlled to heat up so as to heat up and dry the talc particles that fall onto the guide slope.

[0035] At the same time, the vibration motor 8 can be started to drive the feeding box 4 to vibrate, so as to further reduce the probability of talc particles accumulating and clogging at the feeding port 5 and improve the feeding effect. At the same time, the feeding situation in the feeding cylinder 3 can be observed through the transparent observation window 17. Meanwhile, the feeding pipe 16 is installed below the feeding port of the feeding box 14 through the telescopic pipe. By controlling the extension and retraction of the push rod of the electric telescopic rod 15, the discharge height of the feeding pipe 16 can be adjusted to improve the flexibility of use.

[0036] Furthermore, the control components and modules used in the aforementioned feeding motor 13, crushing motor 7, vibration motor 8, and electric telescopic rod 15 are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve improvements to the software and power supply.

[0037] 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 the 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.
