Description

Technical Field

[0001] This utility model belongs to the technical field of coating production feeding equipment, and in particular relates to a feeding device for a pre-dispersion mixing tank in coating production. Background Technology

[0002] Pre-dispersion mixing tanks for paint production are mainly used in the pre-dispersion mixing process before paint production. It is usually necessary to put the corresponding materials into the pre-dispersion mixing tank. When adding bagged powder materials, a corresponding feeding device is required for material delivery.

[0003] In general, the feeding device of the pre-dispersion mixing tank in the coating production uses a hopper with a receiving capacity as a powder material collection device. The material filled in the packaging bag is sent to the top of the hopper by a conveyor belt and a tilting guide plate. The packaging bag is temporarily intercepted by the upper interception device of the tilting guide plate so that the operator can open the packaging bag. Most of the current structures require manual operation to remove the seam and open the bag, which is inefficient and can easily affect the pre-dispersion processing efficiency.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] This utility model embodiment provides a feeding device for a pre-dispersion mixing tank in coating production, such as... Figures 1-7 As shown, the feeding device for a pre-dispersion mixing tank in coating production includes:

[0028] The collection chamber 110 has an open top, a support platform 120 at one end of the collection chamber 110, and a barrier 200. The support platform 120 is equipped with a guide plate 400, one side of which is hinged to the side wall of the collection chamber 110. The support platform 120 is equipped with a hydraulic push rod to push the guide plate 400 on one side to achieve tilting and overturning, similar to the unloading process of a dump truck. The barrier 200 includes a deflecting upright 210 and an intercepting rod 220 rotatably connected to the deflecting upright 210. The bottom of the collection chamber 110 is equipped with a feeding channel to the pre-dispersion mixing tank for paint production.

[0029] The intercepting rod 220 includes a deflecting rod 221 and a lower guard rod 222. The deflecting rod 221 and the lower guard rod 222 are connected by two sets of connecting rods 223. The deflecting upright rod 210 is equipped with a rotary motor, and the motor shaft of the rotary motor is connected to the deflecting rod 221.

[0030] The guide plate 400 is provided with a conveyor belt 300 on the side away from the collection bin 110; the guide plate 400 receives the packaging bags delivered by the conveyor belt 300. After the packaging bags reach the guide plate 400, the guide plate 400 is rotated by the hydraulic flipping mechanism of the guide plate 400 to change the tilt state of the packaging bags. At this time, the blocking member 200 is horizontally intercepted in the guide plate 400 to prevent the packaging bags from sliding directly into the collection bin 110 in advance. The above structural features are basically the same as the existing technical structure, and the corresponding technical structure can refer to the existing technical equipment.

[0031] The intercepting bar 220 is equipped with a bag-opening mechanism for breaking the packaging bag; the bag-opening mechanism includes a bag-opening track 230 and a cutting blade assembly 240. The bag-opening track 230 includes a guide rail 231 and a retainer 232. The retainer 232 is engaged with the intercepting bar 220, and the cutting blade assembly 240 slides on the guide rail 231. The packaging bag, which is sent to the guide plate 400 via the conveyor belt 300, is blocked by the intercepting bar 220. The bag-opening mechanism is laterally intercepted in front of the packaging bag in the sliding direction. The cutting blade assembly 240 cuts the packaging bag as it slides along the bag-opening track 230.

[0032] The cutter assembly 240 includes an embedded slider 242 and a connecting plate 243. The connecting plate 243 is provided with a sharp blade 244. The embedded slider 242 slides in a sliding groove 201 provided inside the guide rail 231. The connecting plate 243 serves as an extension component to ensure that the sharp blade 244 can cut the packaging bag. In actual use, after the blocking member 200 intercepts the packaging bag, the sharp blade 244 can contact the packaging bag. Generally, this is when the guide plate 400 deflects, and the packaging bag has already been inserted by the sharp blade 244 during its slide. As the cutter assembly 240 is manually pulled to expand the damage area, the material flows out of the packaging bag. Subsequent operations are basically the same as in the existing method.

[0033] The main purpose of the blocking component 200 here is to open the packaging bag and prevent it from sliding directly into the collection bin 110. The collection bin 110 is equipped with an arc-shaped rod 130. After the packaging bag is unloaded, it stops on the arc-shaped rod 130 under the obstruction. The arc-shaped rod 130 is arranged parallel to the direction in which the packaging bag slides in, and there are multiple sets of arc-shaped rods 130 distributed at intervals to avoid affecting the material discharge.

[0034] In this embodiment, the cutter assembly 240, in conjunction with the bag opening track 230, completes rapid packaging bag destruction, optimizes the bag opening and unpacking operation for operators, thereby saving bag opening processing time in the material feeding stage and effectively improving the feeding efficiency of the pre-dispersion mixing tank in coating production.

[0035] In a preferred embodiment of this invention, the number of card holders 232 is two sets and each card holder 232 is provided with an arc-shaped slot. The card holder 232 engages with the interceptor rod 220 through the slot.

[0036] In this embodiment, the card holder 232 is reinforced by bolt fixing in addition to the snap-fit ​​connection to ensure the stability of the bag opening track 230. The snap-fit ​​connection between the card holder 232 and the intercepting rod 220 is located between the two sets of connecting rods 223. When the cutter assembly 240 pushes back and forth, the connecting rods 223 will help to distribute the thrust and avoid the force being concentrated on the bolts of the card holder 230.

[0037] In a further preferred embodiment of this utility model, the sliding groove 201 adopts a pentagonal structure, wherein the bottom surface of the sliding groove 201 is composed of several sets of segmented blocks 233 arranged in an array at intervals, and the segmented blocks 233 form a discharge port 202. During the sliding process of the cutter assembly 240, the material entering the sliding groove 201 will slide down along the discharge port 202 onto the guide plate 400, and then reach the collection bin 110 from the guide plate 400. In actual use, it was found that the pulling was obstructed, and the sliding groove 201 can be cleaned by air blowing; cleaning should be carried out after the material is unloaded.

[0038] As a preferred embodiment of this example, the embedded slider 242 is further provided with a toggle plate 241, which is arranged perpendicular to the guide rail 231.

[0039] In this embodiment, the function of the toggle plate 241 is to pull the embedded slider 242 to move.

However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
