Description

Technical Field

[0001] This utility model relates to the field of liquid feeding device technology, and in particular to a plugging block. Background Technology

[0002] Liquid feeders are widely used in various industrial production processes to transport liquid materials to the production line. Some extruders are equipped with a plugging block. When the liquid feeder is feeding material, the nozzle of the liquid feeder is connected to the inlet of the plugging block. The nozzle injects liquid into the extruder through the plugging block, allowing the liquid to enter the screw of the extruder for further processing.

[0003] Most existing plugging blocks adopt a fixed design, which has limitations in practical applications and can lead to problems such as unstable liquid flow and clogging. Utility Model Content

[0004] Based on the aforementioned problems in the prior art, the purpose of this application is to provide a plugging block that forms a pressure-stabilizing groove within its body, thereby enabling stable liquid flow.

[0005] The technical solution adopted by this application to solve its technical problem is: a plugging block, including a body, the body including a surrounding plate and a connecting plate, the surrounding plate being disposed on the connecting plate and defining an outer connecting plate and an inner connecting plate, the outer connecting plate being located outside the surrounding plate, the inner connecting plate being located inside the surrounding plate, the inner connecting plate and the surrounding plate together forming a pressure stabilizing groove, and an inlet communicating with the pressure stabilizing groove being provided on the inner connecting plate.

[0006] Furthermore, the enclosure includes a first side panel, a front panel, a second side panel, and a rear panel. One side of the first side panel is connected to one side of the front panel, the other side of the front panel is connected to one side of the second side panel, the other side of the second side panel is connected to one side of the rear panel, and the other side of the rear panel is connected to the other side of the first side panel. The bottoms of the first side panel, the front panel, the second side panel, and the rear panel are fixedly connected to a connecting plate.

[0007] Furthermore, the front plate surface forms a first arc-shaped portion and a second arc-shaped portion, and the rear plate surface forms a third arc-shaped portion and a fourth arc-shaped portion, the third arc-shaped portion being disposed corresponding to the first arc-shaped portion, and the fourth arc-shaped portion being disposed corresponding to the second arc-shaped portion.

[0008] Furthermore, the outer surfaces of the first side plate, the front plate, the second side plate, and the rear plate are all perpendicular to the surface of the connecting plate.

[0009] Furthermore, the inner surface of the second side plate is provided with an inclined surface.

[0010] Furthermore, an installation port is provided on the external connection board.

[0011] The beneficial effects of this application are as follows: In use, the plugging block is placed on the extruder, and then the nozzle is connected to the liquid inlet of the plugging block. The nozzle injects liquid into the extruder through the liquid inlet. Since the inner connecting plate and the surrounding plate together form a pressure stabilizing tank, and the inner connecting plate is provided with a liquid inlet communicating with the pressure stabilizing tank, when some gas is generated in the extruder during the transportation of liquids of different viscosities, this gas can enter the pressure stabilizing tank. The pressure stabilizing tank can stabilize the gas pressure in the screw cavity, thereby achieving a relatively stable liquid flow rate. Attached Figure Description

Detailed Implementation

[0016] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 and Figure 2 As shown, a plugging block of this utility model includes a body, which includes a surrounding plate 1 and a connecting plate 2. The surrounding plate 1 is disposed on the connecting plate 2 and defines an outer connecting plate 212 and an inner connecting plate 222. The outer connecting plate 212 is located outside the surrounding plate 1, and the inner connecting plate 222 is located inside the surrounding plate 1. The inner connecting plate 222 and the surrounding plate 1 together form a pressure stabilizing groove 3. An inlet 23 communicating with the pressure stabilizing groove 3 is provided on the inner connecting plate 222.

[0018] Thus, the plugging block of this utility model is used by placing it on an extruder, then connecting the nozzle to the liquid inlet 23 of the plugging block, and injecting liquid into the extruder through the nozzle. Since the inner connecting plate 222 and the surrounding plate 1 together form a pressure stabilizing groove 3, and the inner connecting plate 222 is provided with a liquid inlet 23 communicating with the pressure stabilizing groove 3, when some gas is generated in the extruder during the transportation of liquids of different viscosities, this gas can enter the pressure stabilizing groove 3, which can stabilize the gas pressure in the screw cavity, thereby achieving a relatively stable liquid flow rate.

[0019] Optionally, the enclosure 1 includes a first side panel 11, a front panel 12, a second side panel 13, and a rear panel 14. One side of the first side panel 11 is connected to one side of the front panel 12, the other side of the front panel 12 is connected to one side of the second side panel 13, the other side of the second side panel 13 is connected to one side of the rear panel 14, and the other side of the rear panel 14 is connected to the other side of the first side panel 11. The bottoms of the first side panel 11, the front panel 12, the second side panel 13, and the rear panel 14 are fixedly connected to the connecting plate 2.

[0020] By setting the first side plate 11, the front plate 12, the second side plate 13 and the rear plate 14 connected in sequence, it is easy to form the pressure stabilizing groove 3 and to fix the plugging block on the extruder.

[0021] Furthermore, a first arcuate portion 121 and a second arcuate portion 122 are formed on the surface of the front plate 12, and a third arcuate portion 141 and a fourth arcuate portion 142 are formed on the surface of the rear plate 14. The third arcuate portion 141 is provided corresponding to the first arcuate portion 121, and the fourth arcuate portion 142 is provided corresponding to the second arcuate portion 122. The twin-screw extruder has two screws. By providing the first arcuate portion 121 and the third arcuate portion 141, it is convenient to allow space for one of the twin screws. By providing the second arcuate portion 122 and the fourth arcuate portion 142, it is convenient to allow space for the other screw in the twin screw, thereby making the connection between the plug block and the extruder more compact.

[0022] In this embodiment, the outer surfaces of the first side plate 11, the front plate 12, the second side plate 13, and the rear plate 14 are all perpendicular to the surface of the connecting plate 2. Thus, when the plugging block is fixed in the extruder, the outer surfaces of the first side plate 11, the front plate 12, the second side plate 13, and the rear plate 14 are tightly fitted to the inner wall of the extruder, making the plugging block tightly connected to the extruder.

[0023] Furthermore, the inner surface of the second side plate 13 is provided with an inclined surface 131, thereby improving the overall strength of the plugging block. Preferably, the outer connecting plate 212 is provided with mounting ports 211, which facilitates the secure locking of the outer connecting plate 212 to the extruder mounting position using screws. The mounting ports 211 include a first mounting port 2111 on one side of the outer connecting plate 212 and a second mounting port 2112 on the other side of the outer connecting plate 212. There are three first mounting ports 2111 and three second mounting ports 2112, thereby achieving secure fixing of the plugging block to the extruder.

[0024] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
