Description

Technical Field

[0001] This utility model relates to the technical field of release paper production equipment, and in particular to a mixing device and equipment for coating materials. Background Technology

[0002] Release paper is made from coated paper. Coated paper is produced by coating the surface of base paper with a polyethylene (PE) film, which provides oil and water resistance and heat sealing properties, and is commonly used in packaging, food, and other fields. Specifically, the coating process involves melting polyethylene granules at high temperature and then applying them to the surface of release paper using a roller, followed by cooling and solidification to form a PE film.

[0003] With the updating and improvement of the coating process, some manufacturers use a mixture of polyethylene granules of various specifications. This means that before the polyethylene granules are melted at high temperatures, various solid polyethylene granules need to be mixed using a mixing device. Generally, existing mixing equipment is mostly a paddle mixer, mainly consisting of a mixing tank and a mixing mechanism. The mixing mechanism uses a motor to drive the mixing blades on the mixing shaft to mix the materials in the mixing tank. However, due to cost control, some manufacturers do not use automated material suction devices for feeding, but instead use manual feeding. Especially when the mixing tank is large in height and volume, the material needs to be manually poured into the opening at the top of the mixing tank. This manual feeding process is time-consuming and labor-intensive, resulting in poor convenience. Utility Model Content

[0021] This disclosure provides a mixing device for coating materials, including a frame, a mixing mechanism, a tilting trough, and a material tank. A material tank is fixedly installed on the frame, and the material tank has a communicating mixing chamber and a feeding channel. A feeding sleeve is placed inside the mixing chamber, and the feeding sleeve is spaced and aligned with the feeding channel. The mixing mechanism includes a drive assembly and a feeding screw. The drive assembly is disposed on the material tank and is used to drive the feeding screw to rotate. The feeding sleeve is sleeved on the feeding screw, and the feeding screw extends into the feeding channel. The tilting trough is located on the lower side of the material tank, and the tilting trough has a collection trough, which communicates with the feeding channel.

[0022] Please see Figures 1 to 4 To better understand the coating material mixing device 10 of this application, the following further explanation of the coating material mixing device 10 is provided: One embodiment of the coating material mixing device 10 includes a frame 100, a mixing mechanism 300, a tilting trough 400 and a tilting trough 400. The material hopper 200 is fixedly installed on the frame 100. The material hopper 200 has a connected mixing chamber 201 and a feeding channel 202. The mixing chamber 201 has a feeding sleeve 210 inside, and the feeding sleeve 210 is aligned with the feeding channel 202 at intervals. The stirring mechanism 300 includes a drive assembly 310 and a feeding screw 320. The drive assembly 310 is disposed on the material hopper 200 and is used to drive the feeding screw 320 to rotate. The feeding sleeve 210 is sleeved on the feeding screw 320, and the feeding screw 320 extends into the feeding channel 202. The tilting trough 400 is disposed on the lower side of the material hopper 200. The tilting trough 400 has a collecting trough 401, and the collecting trough 401 is connected to the feeding channel 202.

[0023] In this embodiment, the pouring trough 400 is positioned below the side of the material bucket 200 to facilitate the pouring of various solid polyethylene granules into the collection trough 401, allowing the solid polyethylene granules to enter the feeding channel 202. Then, the feeding screw 320 is driven to rotate by the drive assembly 310. Utilizing the relative rotation principle of the feeding screw 320 within the feeding sleeve 210 and the feeding channel 202, the material sequentially passes through the feeding channel 202 into the bottom of the mixing chamber 201, and is then conveyed through the feeding sleeve 210 to the top of the mixing chamber 201, causing the material to scatter back to the bottom of the mixing chamber 201. This cycle repeats, achieving convenient material feeding and mixing. The manual feeding process of the coating material mixing device 10 of this invention is time-saving and labor-saving, offering excellent convenience for manual feeding.

[0024] like Figure 1 and Figure 2 As shown, in one embodiment, the frame 100 includes a top seat 110, a plurality of side columns 120, and a base 130 arranged sequentially. The top seat 110 and the base 130 are fixedly connected through the plurality of side columns 120. The upper end of the material hopper 200 is fixedly connected to the top seat 110, and the lower end of the material hopper 200 is fixedly connected to the base 130. The material hopper 200 is surrounded between the plurality of side columns 120. The motor 3110 of the drive assembly 310 is fixed to one of the side columns 120, and the motor 3110 of the drive assembly 310 is belt-driven with the feeding screw 320. Thus, the motor 3110 of the drive assembly 310 is belt-driven to drive the feeding screw 320 to rotate. The material is conveyed by utilizing the relative rotation principle of the feeding screw 320 within the feeding sleeve 210 and the feeding channel 202.

[0025] It should be noted that other details of the working principle of the motor 3110 of the drive assembly 310 driving the feeding screw 320 to rotate are existing technologies. For example, bearings are installed at both ends of the feeding screw 320 to support the rotation of the feeding screw 320, which will not be described in detail here.

[0026] like Figures 1 to 3 As shown, in one embodiment, the upper and lower ends of the feeding sleeve 210 are respectively surrounded by a plurality of fixing members 2110, which are used to support and position the feeding sleeve 210. This allows the feeding sleeve 210 to be fixedly installed in the mixing chamber 201, and the feeding sleeve 210 to be aligned with the feeding channel 202 at intervals. Thus, material falling back to the bottom of the mixing chamber 201 can re-enter the feeding sleeve 210 for conveying, ensuring uniform mixing even if the material is re-mixed.

[0027] like Figure 2 and Figure 4 As shown, in one embodiment, a plurality of diversion bars 410 are provided at the connection between the pouring trough 400 and the feeding channel 202, and the plurality of diversion bars 410 are arranged at intervals. In this way, when the material is manually poured into the collecting trough 401, the material can be broken up by the plurality of diversion bars 410 before entering the feeding channel 202, preventing the material from clumping and facilitating more uniform mixing of the material in the subsequent process.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, the coating material stirring device 10 further includes a material cover 500, which covers the opening above the material tank 200.

[0029] It is understood that in this embodiment, the material cover 500 is divided into two halves, namely, two semi-circular material covers 500. A supporting square beam is erected between the two semi-circular material covers 500. The supporting square beam is used to position the end of the feeding screw 320, thereby ensuring the reliability and stability of the feeding screw 320 during rotation.

[0030] like Figure 2 As shown, in one embodiment, the bottom of the mixing chamber 201 is conical. This facilitates the accumulation of material at the bottom of the mixing chamber 201, allowing the material to enter the interior of the feeding sleeve 210 through the space between the lower end of the feeding sleeve 210 and the feeding channel 202 for conveying.

[0031] like Figure 1 and Figure 3As shown, in one embodiment, the coating material mixing device 10 further includes a discharge pipe 600, which is connected to the bottom of the mixing chamber 201. The discharge pipe 600 is equipped with a rotating valve blade, which is used to control the opening and closing of the discharge pipe 600. Thus, after mixing is completed, the discharge pipe 600 is opened by rotating the valve blade (not shown) to complete the material discharge operation. Specifically, in this embodiment, the discharge pipe 600 is inclined to facilitate material sliding.

[0032] like Figures 1 to 4 As shown, in one embodiment, the material hopper 200 also has a return port 203 connected to the mixing chamber 201. The return port 203 is located above the tilting trough 400, and the return port 203 is equipped with a pull-out switch valve 220, which is used to control the opening and closing of the return port 203. Thus, the user can open the return port 203 by opening the pull-out switch valve 220, allowing the material in the mixing chamber 201 to fall back into the collection trough 401. The fallen material then re-enters the feeding channel 202, achieving reciprocating mixing and thus preventing excessive accumulation of material in the mixing chamber 201 and improving the uniformity of material mixing.

[0033] like Figure 4 As shown, in one embodiment, a viewing window 204 communicating with the mixing chamber 201 is provided on the side of the material hopper 200, and a window plate 230 is rotatably mounted on the viewing window 204. Thus, the user can rotate and open the window plate 230 to observe the material mixing inside the mixing chamber 201. Specifically, in this embodiment, the window plate 230 is rotatably connected to the material hopper 200 via a hinge, allowing the window plate 230 to rotate open and close the viewing window 204.

[0034] This application also provides a coating material mixing device, including the coating material mixing device 10 described in any of the above embodiments.

[0035] The pouring trough is positioned on the lower side of the material hopper, facilitating the pouring of various solid polyethylene granules into the collection trough, allowing the solid polyethylene granules to enter the feeding channel. Then, the feeding screw is driven by the drive assembly to rotate. Utilizing the relative rotation of the feeding screw within the feeding sleeve and feeding channel, the material sequentially passes through the feeding channel into the bottom of the mixing chamber, and then is conveyed through the feeding sleeve to the top of the mixing chamber, where it scatters back to the bottom. This cycle repeats, achieving convenient material feeding and mixing. The manual feeding process of this coating material mixing equipment is time-saving and labor-saving, offering excellent convenience for manual feeding.

[0036] Compared with the prior art, the present invention has at least the following advantages: The pouring trough is positioned on the lower side of the material hopper, facilitating the pouring of various solid polyethylene granules into the collection trough, allowing the solid polyethylene granules to enter the feeding channel. Then, the feeding screw is driven by a drive assembly.

The manual feeding process of this coating material mixing device is time-saving and labor-saving, offering excellent convenience for manual feeding.
