Description

Technical Field

[0001] This utility model relates to the technical field of polyester film masterbatch mixing, and in particular to a masterbatch mixing and stirring device for polyester film for dry film resist. Background Technology

[0002] To address the shortcomings of traditional mixing techniques, the polyester film masterbatch mixing device employs an advanced structural design and working principle. Through the rotation and reciprocating motion of the lifting rod, the mixing rod rotates on its own axis during its revolution, while simultaneously moving up and down. This design not only increases the mixing range but also effectively improves the mixing efficiency.

[0003] In the prior art, such as the masterbatch mixing and stirring device for polyester film dry film resist proposed in CN214871835U, the upper end of the shell is provided with a feed inlet, the lower end of the shell is provided with multiple support legs, the lower end of the shell is provided with a discharge outlet, and the upper end of the shell is fixedly connected to a drive motor. The output shaft of the drive motor passes through the shell and is fixedly connected to a sleeve. This utility model has a reasonable structural design. Through the rotation and reciprocating motion of the lifting rod, the stirring rod rotates on its own axis during its revolution, and the stirring rod itself also moves up and down, increasing the stirring range and effectively improving the mixing effect.

[0004] When in use, this application utilizes the rotation and reciprocating motion of the lifting rod during stirring to achieve the rotation of the stirring rod during its revolution and the vertical movement of the stirring rod itself, thereby increasing the range of the stirring rod and improving the mixing effect. However, during the mixing process, dead zones are prone to appear in the lower part of the shell, which reduces the mixing efficiency. Furthermore, the friction between the materials inside the shell during mixing can easily generate dust. If this dust is not cleaned in time, it can easily accumulate inside the shell, which can be easily inhaled by workers during maintenance, causing harm to the human body. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a masterbatch mixing and stirring device for polyester film for dry film resist, so as to solve the technical problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A mixing and stirring device for masterbatch of polyester film for dry film resist includes a mixing chamber and a support. The support is fixedly connected to the outer peripheral wall of the mixing chamber and is located below the mixing chamber. A drive motor is fixedly installed on one side of the mixing chamber. The output end of the drive motor is connected to a drive shaft, which extends into the mixing chamber. A mesh cover is rotatably connected between two inner sidewalls of the mixing chamber. A transmission component is provided between the end of the mesh cover near the drive motor and the drive shaft. A plurality of mixing rods are fixedly connected to the outer peripheral wall of the mesh cover. A discharge component is provided at the end of the mesh cover away from the drive motor.

[0008] In a preferred embodiment, the present invention can be further configured such that: the transmission component includes a positioning plate, the positioning plate is disposed between the drive shaft and the mesh cover, two positioning rods are fixedly connected to the side of the positioning plate, the ends of the positioning rods are fixedly connected to the inner wall of the mixing chamber, the outer peripheral wall of the positioning plate is rotatably connected to the mesh cover, and the inner peripheral wall of the positioning plate is rotatably connected to the outer peripheral wall of the drive shaft.

[0009] In a preferred embodiment, the present invention can be further configured as follows: a transmission gear is rotatably mounted on the bottom side of the positioning plate near the drive motor; a drive gear is fixedly mounted on one end of the drive shaft near the transmission gear; an internal gear ring is fixedly connected to one end of the mesh cover near the drive gear; the internal gear ring meshes with the transmission gear; and the drive gear meshes with the transmission gear.

[0010] In a preferred embodiment, the present invention can be further configured such that: the discharge component includes a blade, the blade is fixedly mounted on the end of the drive shaft, and the blade is located on the end of the drive shaft away from the drive motor.

[0011] In a preferred embodiment, the present invention can be further configured such that a storage cover is fixedly connected to the middle of the side of the mixing chamber away from the drive motor, and the storage cover is in communication with the mixing chamber.

[0012] In a preferred embodiment, the present invention can be further configured such that: the outer peripheral wall of the mixing chamber has a number of air inlets, an arc-shaped cover is installed on the outside of the air inlets, and through slots are provided at both ends of the arc-shaped cover.

[0013] In summary, this utility model has at least one of the following beneficial technical effects:

[0014] 1. The masterbatch mixing and stirring device for dry film resist polyester film has a mixing rod end that fits against the inner peripheral wall of the mixing chamber during use, thereby avoiding dead corners when the mixing rod moves in a circular motion to stir, which would result in incomplete mixing of the masterbatch. In addition, the discharge device can greatly reduce the dust of the masterbatch in the mixing chamber, thereby preventing the workers from inhaling a large amount of dust during maintenance and preventing the dust from being dispersed into the air and affecting the environment.

[0015] 2. In this masterbatch mixing and stirring device for polyester film dry film resist, when the drive motor drives the drive shaft to rotate, the drive shaft will drive the drive gear to rotate, which in turn drives the transmission gear to rotate. When the transmission gear rotates, it will drive the internal gear ring that meshes with it to rotate. The internal gear ring will drive the mesh cover to rotate, which will ultimately cause the mixing rod to stir and mix the masterbatch inside the mixing chamber. The masterbatch will be agitated by the rotation of the mixing rod, and then fall due to gravity. This repeated agitation achieves the mixing effect, while avoiding dead corners that may affect the mixing effect.

[0016] 3. The masterbatch mixing and stirring device for dry film resist polyester film includes an air inlet and a through groove that can deliver outside air into the mixing chamber. This facilitates the transportation of dust from all directions within the mixing chamber to the mesh cover and finally to the collection cover. As a result, the dust in the mixing chamber is greatly reduced during masterbatch mixing, preventing excessive dust accumulation that could affect maintenance work. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example:

[0024] Reference Figures 1-3 This utility model discloses a mixing and stirring device for masterbatch of polyester film for dry film resist, including a mixing chamber 1 and a support 2. The support 2 is fixedly connected to the outer peripheral wall of the mixing chamber 1 and is located below the mixing chamber 1. A drive motor 3 is fixedly installed on one side of the mixing chamber 1. The output end of the drive motor 3 is connected to a drive shaft 4. The drive shaft 4 extends into the mixing chamber 1. A mesh cover 5 is rotatably connected between two inner side walls of the mixing chamber 1. A transmission component 6 is provided between the end of the mesh cover 5 near the drive motor 3 and the drive shaft 4. A plurality of mixing rods 7 are fixedly connected to the outer peripheral wall of the mesh cover 5. A discharge component 8 is provided at the end of the mesh cover 5 away from the drive motor 3.

[0025] In this embodiment, the masterbatch of polyester film is placed into the mixing chamber 1, and then the drive motor 3 is started. The drive motor 3 will drive the mesh cover 5 and the irregularly arranged mixing rods 7 through the transmission component 6 to move the masterbatch of polyester film. At the same time, when the drive motor 3 drives the drive shaft 4 to rotate, it will also drive the discharge component 8 to rotate. The end of the mixing rod 7 is in contact with the inner peripheral wall of the mixing chamber 1, so as to achieve the effect of all-round stirring and mixing, avoiding the formation of mixing dead corners and affecting the mixing effect. In addition, the discharge component 8 can draw air to transport the dust generated when mixing the masterbatch in the mixing chamber 1 to the outside of the mixing chamber 1, so as to avoid the dust in the mixing chamber 1 being too large and thus being inhaled by the workers when the mixing chamber 1 is being maintained, causing injury.

[0026] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the transmission component 6 includes a positioning plate 9, which is disposed between the drive shaft 4 and the mesh cover 5. Two positioning rods 10 are fixedly connected to the side of the positioning plate 9. The ends of the positioning rods 10 are fixedly connected to the inner wall of the mixing chamber 1. The outer peripheral wall of the positioning plate 9 is rotatably connected to the mesh cover 5, and the inner peripheral wall of the positioning plate 9 is rotatably connected to the outer peripheral wall of the drive shaft 4.

[0027] In this embodiment, the positioning plate 9 is used to prevent dust in the mixing chamber 1 from entering the components inside the transmission component 6, thereby causing dust accumulation and affecting the driving of the transmission component 6.

[0028] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, a transmission gear 11 is rotatably mounted on the bottom side of the positioning plate 9 near the drive motor 3, a drive gear 12 is fixedly mounted on the end of the drive shaft 4 near the transmission gear 11, and an internal gear ring 13 is fixedly connected to the end of the mesh cover 5 near the drive gear 12. The internal gear ring 13 meshes with the transmission gear 11, and the drive gear 12 meshes with the transmission gear 11.

[0029] In this embodiment, when the drive motor 3 drives the drive shaft 4 to rotate, the drive shaft 4 will drive the drive gear 12 to rotate, and then drive the transmission gear 11 to rotate. When the transmission gear 11 rotates, it will drive the internal gear ring 13 that meshes with it to rotate. The internal gear ring 13 will drive the mesh cover 5 to rotate, so that the mixing rod 7 stirs and mixes the masterbatch inside the mixing chamber 1. The masterbatch will be moved by the rotation of the mixing rod 7, and then fall by gravity. Repeatedly moving the masterbatch achieves the mixing effect, while avoiding dead corners that affect the mixing effect.

[0030] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, the discharge component 8 includes a blade 14, which is fixedly installed at the end of the drive shaft 4 and is located at the end of the drive shaft 4 away from the drive motor 3.

[0031] In this embodiment, the blade 14 will rotate with the drive shaft 4. When the blade 14 rotates, it will draw in the air in the mixing chamber 1 and simultaneously drive the dust into the mesh cover 5, thereby reducing the dust in the mixing chamber 1.

[0032] In a further preferred embodiment of this utility model, such as Figure 1-3 As shown, a storage cover 15 is fixedly connected to the middle of the side of the mixing chamber 1 away from the drive motor 3, and the storage cover 15 is connected to the mixing chamber 1.

[0033] In this embodiment, the storage cover 15 is installed on the middle side of the mixing chamber 1, so that the storage chamber is connected to the mesh cover 5. Therefore, when the drive motor 3 drives the blades 14 to rotate, the dust will enter the mesh cover 5 and then be transported to the storage cover 15 through the conveying of the blades 14, thereby achieving the effect of avoiding the accumulation of dust in the mixing chamber 1.

[0034] In a further preferred embodiment of this utility model, such as Figure 1-3As shown, the outer peripheral wall of the mixing chamber 1 has a number of air inlets 16, and an arc-shaped cover 17 is installed on the outside of the air inlet 16. Both ends of the arc-shaped cover 17 have through grooves 18.

[0035] In this embodiment, the air inlet 16, in conjunction with the through groove 18, can deliver outside air into the mixing chamber 1, so that dust in all directions in the mixing chamber 1 can be delivered into the mesh cover 5 and finally into the collection cover 15. Thus, when the masterbatch is mixed, the dust in the mixing chamber 1 can be greatly reduced, avoiding excessive dust accumulation, which would affect the maintenance work of the staff.

[0036] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
