Abstract
Description
Technical Field
[0001] This application relates to the field of screening equipment technology, and in particular to a screening device for adhesive feeding. Background Technology
[0002] Adhesives or glues typically require sieving during the manufacturing process. The main purpose of sieving is to remove oversized or undersized particles, ensuring that the particle size meets requirements, thereby improving product quality and performance. After the raw materials for adhesives or glues undergo mixing, drying, and other processes, sieving is necessary. Vibrating screens, rotary screens, and other similar equipment are commonly used for sieving. This equipment separates oversized or undersized particles, retaining only particles that meet the required specifications to ensure the quality of the adhesive or glue.
[0003] Existing screening devices are often complex in structure. They achieve screening primarily by first separating the binder raw material particles according to different sizes using a sieve plate, and then collecting the particles on the sieve plate by scraping. Such devices are not only complex in structure, but also present significant difficulties in particle collection during the screening process. Utility Model Content

[0023] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0024] This application discloses an adhesive feeding and screening device.
[0025] Reference Figure 1 and Figure 2 An adhesive feeding and screening device includes a screening box 1 and two collection cylinders 2 and 3 placed at the bottom of the screening box 1. The screening box 1 has a feed inlet 11 at its top, and a hopper 111 is connected to the feed inlet 11. Collection cylinders 2 and 3 are both connected to the interior of the screening box 1. Adhesive raw materials, after being screened into particles of different sizes, enter collection cylinders 2 and 3 respectively. The bottom of the screening box 1 has a conical structure to help the adhesive raw material particles fall quickly and completely into the collection cylinders 2 and 3 below. A screening plate 4 is hinged in the screening box 1 for screening the adhesive raw materials entering the screening box 1.
[0026] Reference Figure 3 and Figure 4Specifically, the screening box 1 has a discharge port 12 at the bottom of its conical structure, and the top of the collecting cylinder 2 is integrally provided with a connecting pipe 21 that communicates with the interior, and the connecting pipe 21 is seamlessly connected to the discharge port 12. At the same time, the bottom of the screening box 1 has a discharge ring groove 13 that is coaxial with the discharge port 12, and a disc-shaped collecting ring frame 5 is fixedly fitted on the connecting pipe 21, and the collecting ring frame 5 is directly opposite the discharge ring groove 13.
[0027] After the raw material is screened, a portion will first enter the collection cylinder 2 through the discharge pipe. At this time, the other portion of the raw material will remain on the screen plate 4. A baffle assembly 6 is provided in the collection cylinder 2. When the large or small particles of raw material being screened have completely entered the collection cylinder 2, the baffle assembly 6 will close the discharge port 12.
[0028] Refer to 4 and Figure 5 A retaining ring 51 is also provided on the connecting pipe 21 between the bottom of the collecting ring frame 5 and the screening box 1. The retaining ring 51 is adapted to the discharge ring groove 13 and connected to a cylinder 52. In the initial state, the retaining ring 51 closes the discharge ring groove 13 under the drive of the cylinder 52. When a part of the raw material completely enters the collecting cylinder 2, the retaining ring 51 will open the discharge ring groove 13 under the drive of the cylinder 52. At this time, the screening plate 4 rotates, and the remaining raw material particles will fall and fall into the collecting ring frame 5 through the discharge ring groove 13. The collecting ring frame 5 is connected to the collecting cylinder 3, so the remaining raw material particles can be finally collected into the collecting cylinder 3 through the collecting ring frame 5, completing the screening process.
[0029] Preferably, the discharge annular groove 13 is formed on the conical structure at the bottom of the screening box 1, and the discharge annular groove 13 is positioned close to the discharge port 12. This design ensures that the raw material particles can completely fall into the discharge annular groove 13, preventing leakage. Compared to a structure where both the discharge port 12 and the discharge annular groove 13 are on the same horizontal plane, this structure more easily utilizes the conical structure at the bottom of the screening box 1 to collect the screened adhesive raw material particles.
[0030] Reference Figure 2 and Figure 3 Specifically, the baffle assembly 6 includes a mounting frame 61 disposed along the axis of the screening box 1 inside the collection cylinder 2, and an electric push rod 62 fixedly mounted on the mounting frame 61. The output end of the electric push rod 62 is connected to a baffle 63, which slides through the connecting pipe 21. When it is necessary to close the discharge port 12, the electric push rod 62 simply drives the baffle 63 upward. When opening the discharge port 12, the baffle 63 is driven in the opposite direction, causing it to disengage from the connecting pipe 21. Since the internal cross-sectional area of the collection cylinder 2 is larger than that of the connecting pipe 21, the raw material particles can smoothly enter the collection cylinder 2 after the baffle 63 disengages from the connecting pipe 21.
[0031] Preferably, the side of the stop block 63 furthest from the electric push rod 62 has a convex structure 631, so that when the stop block 63 closes the discharge port 12, the edge of the stop block 63 coincides with the edge of the discharge port 12, and the top of the stop block 63 is higher than the discharge port 12. Under this condition, raw material particles that fall vertically to the discharge port 12 can slide down to the discharge ring groove 13 under the action of gravity.
[0032] Preferably, the cross-section of the baffle 63 is larger than the cross-sectional area of the electric push rod 62, so that when the raw material particles enter the collection cylinder 2, the baffle 63 can completely block the electric push rod 62 in the vertical direction, preventing the particles from entering the gap between the electric push rod 62 and the baffle 63.
[0033] Reference Figure 2 and Figure 6 Furthermore, the screening plate 4 specifically includes a mounting frame 41 and a screening plate 42 movably disposed inside the mounting frame 41. An electric telescopic rod 7 is hinged to the inner side of the screening box 1, and the mounting frame 41 is hinged to the output end of the electric telescopic rod 7. The electric telescopic rod 7 is used to drive the screening plate 4 to rotate, thereby releasing the remaining raw material particles after screening.
[0034] A plurality of springs 43 are arranged at equal intervals along the circumference of the inner side of the mounting frame 41, and the other end of each spring 43 is connected to the screen plate 42. A motor 44 is also installed on the mounting frame 41 at the bottom of the screen plate 42, and a cam 45 is fixedly fitted on the output shaft of the motor 44, abutting against the bottom of the screen plate 42. When the motor 44 drives the cam 45 to rotate, the cam 45 causes the screen plate 42 to shake continuously, thereby enhancing the screening effect. Furthermore, the shaking effect of the screen plate 42 is even better under the action of the springs 43.
[0035] Furthermore, a stepped groove 14 is provided inside the screening box 1. When the screening plate 4 is kept horizontal, the top side of the mounting frame 41 abuts against the bottom of the stepped groove 14. In this state, the area of the screening plate 42 is larger than the lateral area of the space enclosed by the stepped groove 14, which makes screening more complete and prevents some particles from falling out from the gaps between the screening plate 42 and the springs 43. The stepped groove 14 also limits the screening plate 4, preventing it from tilting during screening.
[0036] The implementation principle of the adhesive feeding and screening device in this application is as follows:
[0037] By using the discharge port 12 at the bottom of the screening box 1, the annular trough, and the screening plate 4 hinged inside the screening box 1, two raw materials of different particle sizes can be collected sequentially by one device when screening adhesive raw material particles. This greatly reduces the difficulty of collecting raw materials after screening and improves the convenience of raw material screening and collection.
[0038] Simultaneously, the screen plate 4 is designed with a built-in vibration function. Specifically, the motor 44 drives the cam 45 to rotate, and the cam 45 abuts against the screen plate 42, which is connected to the mounting frame 41 by a spring 43. The cam 45 drives the screen plate 42 to vibrate, and the vibration effect is amplified by the spring 43, resulting in more thorough screening of the raw materials.
[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
