Description

Technical Field

[0001] This utility model relates to the field of color masterbatch drying technology, specifically a feeding device for color masterbatch drying. Background Technology

[0002] Masterbatch, also known as color masterbatch or color seed, is a new type of colorant specifically for polymer materials, and is also called pigment preparation. Masterbatch is mainly used in plastics.

[0003] Masterbatch drying is a crucial pretreatment step in plastic processing, primarily used to remove moisture and volatiles from the masterbatch to prevent bubbles, surface defects, or performance problems during subsequent processing (such as injection molding and extrusion). During the masterbatch drying process, the masterbatch is placed in a drying chamber for drying treatment. Feeding is required during the drying process, but existing feeding devices are not suitable for intermittent feeding. Therefore, those skilled in the art have proposed a feeding device for masterbatch drying to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for drying masterbatch, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A feeding device for drying masterbatch includes a drying box, a feeding rack installed on the top of the drying box, a connecting seat installed on the top of the feeding rack, a feeding hopper rotatably mounted on the connecting seat, the bottom of the connecting seat communicating with the feeding rack, and a plurality of first feeding ports distributed in an annular shape at equal angles on the top of the connecting seat, and a second feeding port corresponding to the first feeding ports on the bottom of the feeding hopper, and further includes;

[0007] A feeding mechanism is provided in the connecting seat and the feeding frame, and is used to feed the masterbatch.

[0008] A drive mechanism is mounted on the unloading frame and is used to drive the loading hopper to rotate.

[0009] As a further embodiment of this utility model: the unloading rack is equipped with several stirring rods that are inserted into the loading hopper.

[0010] As a further embodiment of this utility model: the feeding mechanism includes a movable head, a connecting rod connected to the movable head, a crossbar connected to the end of the connecting rod away from the movable head, actuating plates installed at both ends of the crossbar, and a swinging component connected to the movable head.

[0011] As a further embodiment of this utility model: the swinging component includes a cam installed on the outer wall of the hopper, a slide rod connected to the movable head is slidably disposed on the connecting seat, a movable plate is installed at the end of the slide rod away from the movable head, and the movable plate is connected to the connecting seat by a spring.

[0012] As a further embodiment of this utility model: the driving mechanism includes a motor mounted on the unloading rack, a second gear mounted on the driving end of the motor, and a first gear meshing with the second gear mounted on the outer wall of the loading hopper.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model puts the color masterbatch that needs to be dried into the feeding hopper, then starts the drying equipment in the drying chamber, and then drives the feeding hopper to rotate through the drive mechanism, so that the second feeding port at the bottom of the feeding hopper is intermittently connected with the first feeding port at the top of the connecting seat, thereby realizing the intermittent feeding of color masterbatch, avoiding the feeding of too much color masterbatch and affecting the drying effect. In addition, the color masterbatch entering the feeding rack will be dispersed in all directions in the drying chamber by the feeding mechanism, thus facilitating the uniform drying of the fed color masterbatch.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] Please see Figures 1-3A feeding device for drying masterbatch includes a drying box 1, a feeding rack 2 installed on the top of the drying box 1, a connecting seat 3 installed on the top of the feeding rack 2, a feeding hopper 4 rotatably mounted on the connecting seat 3, the bottom of the connecting seat 3 communicating with the feeding rack 2, and the top of the connecting seat 3 having a plurality of first feeding ports 8 distributed at equal angles in a ring, and the bottom of the feeding hopper 4 having a second feeding port 9 corresponding to the first feeding ports 8, and further includes;

[0020] A feeding mechanism is provided in the connecting seat 3 and the feeding frame 2, and is used to feed the masterbatch.

[0021] A drive mechanism is mounted on the unloading frame 2 and is used to drive the loading hopper 4 to rotate.

[0022] By feeding the masterbatch to be dried into the hopper 4, and then starting the drying equipment in the drying chamber, the hopper 4 is driven to rotate by the drive mechanism, so that the second discharge port 9 at the bottom of the hopper 4 is intermittently connected to the first discharge port 8 at the top of the connecting seat 3, thereby realizing the intermittent feeding of the masterbatch, avoiding the addition of too much masterbatch and affecting the drying effect. The masterbatch entering the discharge rack 2 will be dispersed in all directions in the drying chamber 1 by the feeding mechanism, thus facilitating the uniform drying of the added masterbatch.

[0023] As one embodiment of this utility model, the unloading rack 2 is equipped with a plurality of stirring rods 10 inserted into the loading hopper 4.

[0024] During the process of the drive mechanism driving the feeding hopper 4 to rotate, the stirring rod 10, which is located on the unloading frame 2 and inserted into the feeding hopper 4, can stir the color masterbatch in the feeding hopper 4, so as to prevent the color masterbatch in the feeding hopper 4 from clogging and accumulating at the bottom of the feeding hopper 4 and affecting the intermittent feeding efficiency, and the effect is better.

[0025] As an embodiment of the present invention, the feeding mechanism includes a movable head 15, a connecting rod 16 connected to the movable head 15, a crossbar 17 connected to the end of the connecting rod 16 away from the movable head 15, actuating plates 18 installed at both ends of the crossbar 17, and a swinging component connected to the movable head 15.

[0026] The swinging component includes a cam 11 installed on the outer wall of the hopper 4. A slide rod 13 connected to the movable head 15 is slidably disposed on the connecting seat 3. A movable plate 12 is installed at the end of the slide rod 13 away from the movable head 15. The movable plate 12 is connected to the connecting seat 3 by a spring 14.

[0027] When the second discharge port 9 at the bottom of the feeding hopper 4 and the first discharge port 8 at the top of the connecting seat 3 are aligned, the masterbatch in the feeding hopper 4 will pass through the second discharge port 9 and the first discharge port 8 into the bottom of the connecting seat 3, and then fall into the feeding rack 2. During the falling of the masterbatch, the rotation of the feeding hopper 4 will also drive the cam 11 to rotate. In conjunction with the spring 14 in the tension state, the movable plate 12 can be driven to move left and right back and forth, so that the slide rod 13 can drive the movable head 15 to move left and right back and forth. Through the connecting rod 16 and the crossbar 17, the actuating plate 18 can be driven to swing left and right, thereby actuating the masterbatch falling on both sides of the actuating plate 18 and moving the masterbatch into the interior of the drying chamber 1. This makes the masterbatch in the drying chamber 1 dispersed, which is convenient for uniform drying and has a better effect.

[0028] As one embodiment of the present invention, the driving mechanism includes a motor 7 mounted on the unloading frame 2, a second gear 6 mounted on the driving end of the motor 7, and a first gear 5 meshing with the second gear 6 mounted on the outer wall of the loading hopper 4.

[0029] When feeding color masterbatch, start motor 7. The meshing of first gear 5 and second gear 6 can drive the feeding hopper 4 to rotate. This rotation of the feeding hopper 4 allows the second discharge port 9 at the bottom of the feeding hopper 4 to intermittently connect with the first discharge port 8 at the top of the connecting seat 3, thereby realizing intermittent feeding of color masterbatch. This avoids excessive feeding of color masterbatch, which would affect the drying effect, resulting in better performance.

[0030] This invention involves feeding the masterbatch to be dried into the hopper 4, then starting the drying equipment in the drying chamber. The drive mechanism then drives the hopper 4 to rotate, causing the second discharge port 9 at the bottom of the hopper 4 to intermittently connect with the first discharge port 8 at the top of the connecting seat 3. This intermittent feeding of the masterbatch avoids excessive feeding of the masterbatch, which would affect the drying effect. Furthermore, the masterbatch entering the discharge rack 2 is dispersed throughout the drying chamber 1 by the feeding mechanism, thus facilitating uniform drying of the fed masterbatch.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
