Description

Technical Field

[0001] This utility model belongs to the technical field of stirring equipment, and in particular relates to a stirring device for the production of resin substrates. Background Technology

[0002] Copper clad laminate (CCL) is a special electronic material with a thin copper film coated on the surface of a resin substrate. It is a basic material for manufacturing printed circuit boards (PCBs). The raw materials for producing the resin substrate are generally resin (organic) and ceramic powder (inorganic). In the pre-molding process of the resin substrate, the resin and ceramic powder need to be mixed evenly using a stirring device. The higher the uniformity of the mixing of the resin and ceramic powder, the higher the consistency of the dielectric constants of the two materials, and the better the quality of the resin substrate produced by subsequent molding.

[0003] Patent CN218452113U discloses a mixing tank for cosmetic production. The inner wall of the mixing tank body is relatively smooth. During the mixing process, the raw materials tend to rotate with the mixing mechanism, which weakens the shearing, convection and diffusion effects between the mixing mechanism and the raw materials, thus reducing the mixing effect on the raw materials.

[0004] Therefore, it is necessary to improve the existing stirring devices. Utility Model Content

[0005] The purpose of this invention is to overcome the defects in the existing technology and provide a stirring device for resin substrate production, which improves the uniformity of mixing resin and ceramic powder.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the stirring device and are only for the convenience of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 and 2 As shown, a stirring device for producing resin substrates includes a mixing tank 3 fixedly connected to a base 1, a closable lid 4 on the mixing tank 3, a blade 6 inside the mixing tank 3, a drive mechanism 2 on the base 1 that is pulsatorically connected to the blade 6, a vertically extending insertion tube 401 fixedly connected to the lid 4, a tubular portion 701 slidably coaxially arranged on the inner side of the insertion tube 401, a vertically distributed baffle 7 fixedly connected to the bottom end of the tubular portion 701, and a locking screw 406 on the insertion tube 401.

[0021] The above-mentioned stirring device is suitable for mixing raw materials during the production of resin substrates. Sealing rings are provided between the insertion tube 401 and the tubular part 701, and between the tubular part 701 and the temperature probe 9. These sealing rings improve the sealing performance of the lid 4, preventing leakage of raw materials during mixing. The insertion tube 401 has a radially threaded hole for threaded connection with the locking screw 406. The locking screw 406 has a handle distributed radially, allowing for manual tightening to improve ease of operation. The tubular part 701 is inserted into the insertion tube 401, facilitating the installation and removal of the baffle 7. The height and angle of the baffle 7 can be adjusted by rotating or axially moving the tubular part 701. The locking screw 406 secures the tubular part 701 to the insertion tube. The mutual locking and unlocking between parts 401 enables the locking of the position of the baffle 7. The baffle 7 prevents the raw material from rotating with the blade 6, thereby improving the shearing, convection, and diffusion effects between the blade 6 and the raw material, and enhancing the uniformity of the mixture. Furthermore, the baffle 7 also has a guiding function, which can concentrate the raw material at the center of the mixing tank 3, i.e., at the position of the blade 6, so that the blade 6 can have more full contact with the raw material, thereby achieving cutting and mixing of the raw material and further improving the uniformity of the mixture. When the locking screw 406 is loosened, the tubular part 701 can be manually rotated or pulled. While the blade 6 is stirring the raw material, the angle and height of the baffle 7 can be changed in real time to further stir the raw material and further improve the uniformity of the mixture.

[0022] The drive mechanism 2 includes a motor fixed on the base 1, a drive wheel fixedly connected to the drive shaft of the motor, an installation hole at the bottom of the mixing tank 3, a rotatable shaft coaxially and sealed in the installation hole, one end of the shaft is located inside the mixing tank 3 and fixedly connected to the blade 6, and the other end is located inside the base 1 and fixedly connected to the driven wheel, and the drive wheel drives the driven wheel to rotate through a belt.

[0023] Further improvements include, for example Figure 3 and 4 As shown, a temperature probe 9 is installed inside the tubular part 701, and a temperature regulating mechanism is installed on the mixing tank 3. The temperature probe 9 and the temperature regulating mechanism are electrically connected to each other. The structure of the temperature regulating mechanism is as follows: it includes an air inlet pipe 301 that communicates with the bottom of the mixing tank 3. A pneumatic one-way valve 303 is installed at one end of the air inlet pipe 301 that is connected to the mixing tank 3. An exhaust pipe 405 is installed on the tank cover 4. A filter screen 5 is fixedly connected to the exhaust pipe 405 by a clamp. An observation window 402 and a feeding port 403 are provided on the tank cover 4. A sealing cap 404 is provided on the feeding port 403.

[0024] In the above-mentioned stirring device, the temperature probe 9 is used to detect the temperature of the raw materials. By adjusting the tubular part 701 to different heights, the temperature of the raw materials at different positions can be detected, thereby improving the accuracy of the raw material temperature detection. When the temperature inside the mixing tank 3 is detected to be higher than the set value, high-pressure air is introduced into the air inlet pipe 301. The air enters the mixing tank 3 and carries away the heat from the raw materials through the gaps between them. Then the air is discharged from the exhaust pipe 405 on the tank cover 4, thereby achieving the cooling effect on the raw materials. At the same time, the high-pressure air blows the raw materials, which can also improve the uniformity of the mixing of the raw materials. The pneumatic one-way valve 303 allows air to enter the interior of the mixing tank 3 while blocking the raw materials from entering the interior of the air inlet pipe 301. The filter screen 5 can filter out the raw material powder in the air discharged from the exhaust pipe 405, thereby reducing the leakage and loss of raw materials.

[0025] Further improvements include, for example Figure 7 As shown, the temperature probe 9 has a columnar structure, with its front end extending to the outside of the tubular portion 701 and sealingly connected to it. A threaded sleeve 901 is coaxially fixedly connected to its end. The outer circumferential surface of the top end of the tubular portion 701 is threaded, and the tubular portion 701 is threadedly connected to the threaded sleeve 901. The threaded sleeve 901 covers the outer circumference of the top end of the tubular portion 701, and the two are threadedly connected, enabling the temperature probe 9 to be fixedly installed inside the tubular portion 701. This also facilitates the installation and removal of the temperature probe 9, improving the ease of equipment maintenance.

[0026] Further improvements include, for example Figure 2 As shown, the lid 4 is rotatably connected to the mixing tank 3 via a hinge, and the insertion tube 401 is positioned close to the hinge; the side of the tubular part 701 is provided with scale lines. Positioning the tubular part 701 and the baffle 7 near the hinge allows for greater rotational space during the opening and closing of the lid 4, facilitating their movement to the outside of the mixing tank 3. The scale lines also allow for easy observation of the tubular part 701's position, preventing collisions between the tubular part 701, the baffle 7, or the temperature probe 9 and the blade 6, thus reducing the likelihood of damage to the stirring device.

[0027] Further improvements include, for example Figure 4 and 5 As shown, the bottom of the mixing tank 3 is provided with a downwardly extending discharge pipe 302, and the middle of the bottom side of the discharge pipe 302 is provided with a vertically extending bypass pipe 304. The discharge pipe 302 is sealed and slidably fitted with a sealing plug 801. The end of the discharge pipe 302 away from the mixing tank 3 is provided with an end cap 305. A handle 802 coaxially arranged with the discharge pipe 302 is fixedly connected to the sealing plug 801. The handle 802 passes through the end cap 305 and is fixedly connected to the end cap 305 by a pin. The side of the sealing plug 801 near the mixing tank 3 smoothly transitions with the inner wall of the mixing tank 3.

[0028] In the aforementioned mixing device, the discharge pipe 302 can be closed or opened via the sealing plug 801, and the sealing plug 801 can be manually pushed and pulled via the handle 802. When the discharge pipe 302 is closed, the handle 802 is inserted into the discharge pipe 302 until the side of the sealing plug 801 adjacent to the mixing tank 3 is flush with the inner wall of the mixing tank 3. At this time, the end cap 305 and the handle 802 are fixed by a pin. In order to insert the pin, pin holes need to be opened at the corresponding positions of the end cap 305 and the handle 802. The pin connection allows for the positioning of the sealing plug 801, ensuring its sealing effect on the discharge pipe 302. When the raw materials are mixed and need to be discharged, the sealing plug 802 is pulled outward from the discharge pipe 302 by the handle 802 until it reaches the side of the bypass pipe 304 away from the mixing tank 3. At this point, the bypass pipe 304 connects the inside and outside of the mixing tank 3, allowing the raw materials to be discharged normally. This design greatly improves the convenience of discharging materials from the mixing device.

[0029] A further improvement is that the discharge pipe 302 is positioned close to the baffle 7. When the discharge pipe 302 is positioned close to the baffle 7, the material near the discharge pipe 302 can be agitated by the baffle 7 when the material is discharged from the discharge pipe 302, preventing the material from accumulating at the inlet of the discharge pipe 302 and causing blockage, thus greatly improving the smoothness of material discharge inside the mixing device.
