[0002] In the field of extrusion production, precise and stable control of material discharge velocity is crucial to ensuring product quality. However, actual production often faces the following core challenges: linear and stepless fine adjustment of the discharge velocity is difficult; the control process is sluggish and cannot quickly adapt to process changes; high-viscosity or heat-sensitive materials are prone to localized stagnation, agglomeration, or even degradation during control; changes in the external flow channel structure can easily cause pressure fluctuations, leading to discharge pulsation and uneven cross-sectional dimensions; and complex control mechanisms are prone to clogging and difficult to maintain. These pain points severely restrict the production efficiency and yield of high-precision extruded products.

[0003] To address these issues, we provide a material discharge speed control device for extrusion production. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1 to 4 This utility model is a discharge speed control device for extrusion production, including a connecting pipe 1, a discharge sleeve 2, and a plug 3. The connecting pipe 1 is fixedly sleeved to the discharge port of the production device, and the discharge sleeve 2 is fixedly sleeved to the other end of the connecting pipe 1. A discharge branch pipe 202 is provided on one side wall of the discharge sleeve 2, so that the material enters the discharge sleeve 2 through the connecting pipe 1 and is discharged from the discharge branch pipe 202, thereby completing the discharge. The plug 3 is sleeved inside the discharge sleeve 2, and a side push screw 101 is sleeved inside the discharge sleeve 2. Rotating the side push screw 101 pushes the plug 3 closer to or away from the pipe port of the connecting pipe 1, so that the plug 3 blocks the material discharged from the connecting pipe 1, thereby controlling the discharge speed.

[0027] Specifically, the diameter of the discharge pipe sleeve 2 is larger than that of the connecting pipe 1. Both ends of the discharge pipe sleeve 2 are closed. One end of the discharge pipe sleeve 2 is fixedly connected to the connecting sleeve 201. The connecting sleeve 201 is fixedly sleeved on one end of the connecting pipe 1. The plug 3 is sleeved inside the discharge pipe sleeve 2. A side push screw 101 is passed through one end face of the discharge pipe sleeve 2. One end of the side push screw 101 is connected to the plug 3. A discharge branch pipe 202 is fixedly connected to one side wall of the discharge pipe sleeve 2.

[0028] Furthermore, a blocking cylinder 301 is fixedly provided on one end face of the blocking plug 3 near the connecting pipe 1. The blocking cylinder 301 is open at one end away from the blocking plug 3. The blocking cylinder 301 is sleeved inside the connecting pipe 1. A set of material passage holes 301a are opened through the side wall of the blocking cylinder 301. The diameter of the blocking plug 3 is larger than the outer diameter of the connecting pipe 1. The side push screw 101 pushes the blocking plug 3 to move, so that the blocking cylinder 301 slides in the connecting pipe 1. When the blocking plug 3 gradually approaches the port of the connecting pipe 1, the part of the material passage hole 301a extending out of the connecting pipe 1 decreases, so that the gap of the material in the connecting pipe 1 flowing out of the material passage hole 301a is reduced, thereby reducing the discharge speed.

[0029] Furthermore, a threaded opening 301b is fixedly provided on the end face of the plug 3 away from the connecting pipe 1. A sealing tube 301c is screwed onto the outer thread of the threaded opening 301b. An end plate 301c-1 is fixedly provided on the end face of the sealing tube 301c near the plug 3. The end face of the side push screw 101 is rotatably connected to the end plate 301c-1. A sliding sleeve 203 is fixedly connected to the end face of the discharge pipe sleeve 2 away from the connecting pipe 1. The sealing tube 301c is slidably sleeved in the sliding sleeve 203. The side push screw 101 is screwed through the closed end face of the sliding sleeve 203 away from the discharge pipe sleeve 2. The side push screw 101 rotates, causing the sealing tube 301c to slide in the sliding sleeve 203, preventing the material from contacting the side push screw 101 and avoiding the material from affecting the rotation of the side push screw 101.

[0030] Furthermore, a screw end cap 101a is fixedly provided at the end of the side push screw 101 away from the blockage plug 3, and a screw rotation plate 101a-1 is fixedly provided on the outside of the screw end cap 101a for rotating the side push screw 101.

[0031] The operation process in this embodiment is as follows:

[0032] The connecting pipe 1 is fixedly sleeved onto the discharge port of the production device. The side push screw 101 is rotated, and the side push screw 101 pushes the blocking plug 3 to move, so that the blocking cylinder 301 slides in the connecting pipe 1. When the blocking plug 3 gradually approaches the port of the connecting pipe 1, the part of the material passage hole 301a extending out of the connecting pipe 1 decreases, so that the gap of the material in the connecting pipe 1 flowing out of the material passage hole 301a is reduced, thereby reducing the discharge speed and achieving the technical effect of controlling the discharge speed.

[0033] Example 2

[0034] Please see Figures 1 to 5 Based on Example 1, by setting a locking screw 204b at one end of the sliding sleeve tube 203, after rotating the side push screw 101, the locking screw 204b is rotated so that the locking screw 204b presses against the end face of the screw end cap 101a at one end of the side push screw 101, preventing the side push screw 101 from rotating due to vibration during material discharge, which would cause the blockage plug 3 to move.

[0035] Specifically, an end sleeve 204 is fixedly sleeved on the outer side of the end of the sliding sleeve 203 away from the discharge sleeve 2. A set of support rods 204a are fixedly arranged in a circumferential array on the end face of the end sleeve 204. The support rods 204a extend away from the end of the discharge sleeve 2. A transition beam plate 204a-1 is fixedly provided at the end of the set of support rods 204a away from the end sleeve 204. A locking screw 204b is screwed through the internal thread of the transition beam plate 204a-1.

[0036] Furthermore, a top ball seat 204b-1 is fixedly provided on one end face of the locking screw 204b near the side push screw 101. A hemispherical groove is provided on the end face of the top ball seat 204b-1. A top ball 204b-2 is rolled in the hemispherical groove on the end face of the top ball seat 204b-1. The top ball 204b-2 rests on the end face of the screw end cap 101a.

[0037] Furthermore, a top bead sleeve 204b-3 is fixedly sleeved on the end face of the top bead seat 204b-1, and the top bead 204b-2 penetrates through the end face of the top bead sleeve 204b-3.

[0038] The operation process in this embodiment is as follows:

[0039] After rotating the adjusting side push screw 101, rotate the locking screw 204b to make the top ball 204b-2 press against the screw end cap 101a at one end of the side push screw 101. When the material in the connecting pipe 1 is squeezed out, it will drive the blockage plug 3 and the blockage cylinder 301 to rotate and push the blockage plug 3 to move away from the end of the connecting pipe 1, increasing the distance between the blockage plug 3 and the port of the connecting pipe 1, thereby increasing the discharge speed. At this time, the top ball 204b-2 presses against the side push screw 101 under the action of the locking screw 204b to prevent the side push screw 101 from moving backward, so that the side push screw 101 presses against the blockage plug 3 to prevent the blockage plug 3 from moving, avoid increasing the discharge speed, and keep the discharge speed stable. The top ball 204b-2 and the screw end cap 101a roll contact, and when the side push screw 101 rotates, it prevents the screw end cap 101 from driving the locking screw 204b to rotate.
