Description

Technical Field

[0001] This utility model is a plastic sealant feeding device, belonging to the field of plastic sealant feeding technology. Background Technology

[0002] The currently used feeding rack includes a feeding rack plate, with a baffle at the bottom of the feeding rack plate to hold the molding compound. Two screws are installed between the feeding rack plate and the baffle. To facilitate linear sliding between the feeding rack plate and the baffle, the screws restricting the relative position of the baffle and the feeding rack plate cannot be tightened. After the feeding rack plate is placed in the mold cylinder, the baffle is pulled with one finger. Once the hole in the baffle, the diameter of the molding compound, aligns with the hole in the feeding rack plate, the molding compound in the feeding rack plate falls into the mold cylinder, completing the molding compound feeding. However, during use, the following issues arise: Because there is no reference point when pulling the baffle, the stroke of each pull is inconsistent, causing the hole in the feeding rack plate to misalign with the hole in the baffle, frequently resulting in material jamming and the molding compound not falling smoothly. Furthermore, the screws fixing the baffle cannot be tightened. Once tightened, the bottom baffle of the feeding rack cannot be pulled, so the screws frequently fall off during use, causing the feeding rack to fall apart. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plastic sealant feeding device to solve the problems mentioned in the background art. This utility model provides a reference for the position of the pull baffle to prevent the feeding rack from falling apart.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a plastic sealant feeding device, comprising a feeding rack plate, wherein a plurality of plastic sealant feeding ports are evenly distributed on the upper surface of the feeding rack plate, a baffle is inserted into the bottom of the feeding rack plate, and a plurality of discharge ports initially offset from the plastic sealant feeding ports are distributed on the upper surface of the baffle plate, wherein a side plate is provided on one side of the feeding rack plate for sliding contact with the feeding rack plate, the lower end of the side plate is connected and fixed to the baffle, an ear plate is connected and fixed to one end of the side plate, an extension plate is connected and fixed to the end of the feeding rack plate near the ear plate, two springs in a stretched state are installed between the extension plate and the ear plate, the springs are arranged along the width direction of the feeding rack plate, a lever is rotatably installed at the middle position of the side of the ear plate facing the extension plate, the lever has an L-shaped structure, and a button plate is connected and fixed to the end of the lever away from the ear plate.

[0005] Furthermore, the bottom of the feeding rack plate has two insertion slots, which are arranged along the length of the feeding rack plate. The upper surface of the baffle plate is equipped with two insertion strips that cooperate with the insertion slots, and the two insertion strips are respectively inserted into the two insertion slots.

[0006] Furthermore, the cross-section of the connector strip is dovetail-shaped, and the cross-section of the connector groove is dovetail-shaped.

[0007] Furthermore, a protrusion is fixedly connected to the center of the side of the feeding rack plate facing the spring, and the bend of the lever contacts the protrusion.

[0008] Furthermore, the side of the protrusion facing away from the feeding rack plate is recessed to form a groove, and a magnet block that attracts the lever is glued into the groove.

[0009] Furthermore, two round holes are provided on both the side of the ear plate facing the extension plate and the side of the extension plate facing the ear plate. The two ends of the spring pass through the corresponding two round holes respectively. A limiting plate is provided on the outside of the round hole, and the end of the spring is connected and fixed to the limiting plate.

[0010] Furthermore, the end of the lever furthest from the button plate is rotatably mounted with a connecting ear via a pivot, and the connecting ear is fixedly connected to the ear plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. Insert the connector strip into the connector slot to connect the baffle and the feeding rack plate. Install two springs in tension between the ear plate and the extension plate. Under the action of the spring rebound force, the side plate will fit against one side of the feeding rack plate, thus restricting the relative position of the baffle and the feeding rack plate. There is no need to use screws to connect the baffle and the feeding rack plate, which prevents the feeding rack formed by the baffle and the feeding rack plate from falling apart due to screws falling off.

[0013] 2. Pressing the button panel causes the bend in the lever to press against the feeding rack plate. Because the feeding rack plate is positioned by a clamp, the lever moves the side plate via the ear plate during the pressing process. The side plate then moves the baffle, aligning the discharge port and the inlet on the baffle. This allows the molding compound to fall into the mold cylinder through the aligned discharge and inlet. The extension plate restricts the button panel, limiting its movement to a reference point for the position of the baffle, ensuring alignment between the discharge and inlet and preventing material jamming. The lever design also saves effort. Attached Figure Description

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a plastic sealant feeding device, including a feeding rack plate 1. Multiple plastic sealant feeding ports 2 are evenly distributed on the upper surface of the feeding rack plate 1. A baffle plate 12 is inserted into the bottom of the feeding rack plate 1. Multiple discharge ports 13, initially offset from the plastic sealant feeding ports 2, are distributed on the upper surface of the baffle plate 12. Two insertion slots 15 are provided at the bottom of the feeding rack plate 1, arranged along the length of the feeding rack plate 1. Two insertion strips 14, which cooperate with the insertion slots 15, are installed on the upper surface of the baffle plate 12. The two insertion strips 14 are respectively inserted into the two insertion slots 15. The cross-sections of the insertion strips 14 and the insertion slots 15 are both dovetail-shaped. One side of the feeding rack plate 1 has a side plate 3 that slides in contact with the feeding rack plate 1. The lower end of the side plate 3 is connected to the baffle plate 1. Plate 12 is connected and fixed. One end of side plate 3 is connected and fixed with ear plate 4. The end of feeding rack plate 1 near ear plate 4 is connected and fixed with extension plate 9. Two springs 11 in tension are installed between extension plate 9 and ear plate 4. Springs 11 are arranged along the width direction of feeding rack plate 1 so that insertion strip 14 is inserted into insertion slot 15 to realize the insertion of baffle 12 and feeding rack plate 1. Two springs 11 in tension are installed between ear plate 4 and extension plate 9. Under the action of spring 11 rebound force, side plate 3 is attached to one side of feeding rack plate 1, so that the relative position of baffle 12 and feeding rack plate 1 is restricted. There is no need to use screws to connect baffle 12 and feeding rack plate 1, which prevents the feeding rack formed by baffle 12 and feeding rack plate 1 from falling apart due to screws falling off.

[0022] See Figures 1-4Two round holes 17 are provided on the side of the ear plate 4 facing the extension plate 9 and the side of the extension plate 9 facing the ear plate 4. The two ends of the spring 11 pass through the corresponding two round holes 17 respectively. A limiting plate 10 is provided on the outside of the round hole 17. The end of the spring 11 is connected and fixed to the limiting plate 10. The limiting plate 10 restricts the end of the spring 11.

[0023] See Figures 1-4 A lever 6 is rotatably mounted at the center of the side of the ear plate 4 facing the extension plate 9. The lever 6 has an L-shaped structure. A connecting ear 5 is rotatably mounted at the end of the lever 6 away from the button plate 7 via a pivot. The connecting ear 5 is fixedly connected to the ear plate 4. The button plate 7 is fixedly connected to the end of the lever 6 away from the ear plate 4. A protrusion 8 is fixedly connected to the center of the side of the feeding rack plate 1 facing the spring 11. The bend of the lever 6 contacts the protrusion 8. When the button plate 7 is pressed, the bend of the lever 6 presses against the feeding rack plate 1. Because the feeding rack plate 1 is positioned by a clamp, the lever 6 presses against the spring 1. During the pressing process of the material rack plate 1, the lever 6 drives the side plate 3 to move through the ear plate 4, and the side plate 3 drives the baffle 12 to move, so that the discharge port 13 on the baffle 12 is aligned with the feeding port 2. Thus, the molding material falls into the mold barrel through the aligned discharge port 13 and feeding port 2. Since the extension plate 9 restricts the button plate 7, it makes the button plate 7 contact with the extension plate 9, restricting the movement range of the button plate 7, providing a reference for the position of pulling the baffle 12, so that the discharge port 13 is aligned with the feeding port 2, preventing material jamming. At the same time, the design of the lever 6 saves effort.

[0024] See Figure 1 and Figure 3 The protrusion 8 is recessed on the side facing away from the feeding rack plate 1 to form a groove. A magnet 16 that attracts the lever 6 is glued into the groove. After the magnet 16 and the lever 6 attract each other, the position of the lever 6 is restricted, preventing the lever 6 from swinging randomly.
