Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive production technology, and in particular to a feeding mechanism for hot melt adhesive production. Background Technology

[0002] Hot melt adhesive is a type of plastic adhesive. Within a certain temperature range, its physical state changes with temperature, while its chemical properties remain unchanged. It is non-toxic, odorless, and an environmentally friendly chemical product. The production of hot melt adhesive requires the addition and mixing of some granular or powdered raw materials.

[0003] However, in existing technologies, when adding raw materials to hot melt adhesive production, they are usually added directly and mixed with other raw materials. However, some powdered raw materials are prone to clumping. Without filtering and crushing them, the mixing effect of the raw materials can be affected, thereby reducing the quality of the hot melt adhesive. Moreover, the raw materials need to be weighed before being added, and the efficiency of adding materials after weighing is relatively low, thus reducing the production efficiency of hot melt adhesive. Utility Model Content

[0052] Among them, the crushing roller 122 and the carding plate 123 are in contact with the filter screen plate 110. The crushing roller 122 can crush the agglomerated powdery raw materials so that they can be better screened, while the carding plate 123 can spread out the accumulated powdery raw materials to facilitate screening and crushing.

[0053] A protective box 103 is fixedly installed on the top of the U-shaped plate 102. A connecting shaft 108 passes through the protective box 103. A gear 109 is fixedly installed on the top of the connecting shaft 108. Multiple gears 109 mesh with each other and are movably embedded inside the protective box 103.

[0054] The drive motor 104 is fixedly installed at the top center of the protective box 103, and the output end of the drive motor 104 passes through the protective box 103 and is connected to one of the connecting shafts 108.

[0055] In this embodiment, the drive motor 104 drives one of the connecting shafts 108 to rotate, and the connecting shaft 108 drives two other meshing gears 109 to rotate through the gear 109, thereby causing multiple connecting shafts 108 to rotate, driving the rolling roller 122 and the carding plate 123 to work.

[0056] Example 2, as Figure 1-4 As shown, the weighing assembly includes: a connecting rod 116 is movably embedded in one side of the inside of the feed box 1, a rectangular plate 114 is fixedly sleeved on the outer surface of the connecting rod 116, rectangular grooves 115 are opened on both the front and back sides of the rectangular plate 114, and a weighing plate 118 is fixedly installed inside the rectangular grooves 115.

[0063] In this embodiment, the stepper motor 101 can drive the rectangular plate 114 to flip through the connecting rod 116, so that the weighed raw material falls onto the guide plate 119.

[0064] Working principle: The powder material to be screened is placed inside multiple screening cylinders 106. Then, the drive motor 104 is turned on to drive one of the connecting shafts 108. The connecting shaft 108 drives the gear 109 to rotate. The gears 109 mesh, so multiple connecting shafts 108 can rotate. The connecting shaft 108 drives the crushing roller 122 and the carding plate 123 to screen and crush the powder material. The carding plate 123 spreads the accumulated powder material, making it easier for the crushing roller 122 to crush the lumpy material. The carding plate 123 can push the powder material to spread and move, so that screening can be performed. An arc plate 124 is fixedly installed on one side of the carding plate 123. The arc plate 124 can gather the material attached to the edge of the screening cylinder 106 to the middle part of the filter screen plate 110, which is convenient for crushing and screening. The screened powder falls into the conical cylinder 113 through the filter screen plate 110. The protective box 103 can protect the gear 109 and improve the performance of the gear 109.

[0065] After screening, the raw material falls into the conical cylinder 113. The solenoid valve 112 is opened to transfer the raw material through the inclined discharge pipe 111 to the rectangular trough 115. A weighing plate 118 is fixedly installed inside the rectangular trough 115. The raw material can be weighed through the weighing plate 118. After weighing, the stepper motor 101 is turned on to drive the rectangular plate 114 to rotate through the connecting rod 116, so that the upper and lower sides of the rectangular plate 114 alternate. During the alternation process, the weighed raw material falls onto the guide plate 119 and is accurately conveyed to the mixing mechanism through the discharge port 120. The baffle plate 117 prevents the raw material from spilling out, so that the raw material falls more accurately into the rectangular trough 115 for weighing.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
