Description

Technical Field

[0001] This utility model belongs to the technical field of modified engineering plastics mixing equipment, specifically a high-speed mixer for processing modified engineering plastics. Background Technology

[0002] Chinese Patent CN220409282U discloses a high-speed mixer for processing modified engineering plastics, comprising: a mixing tank; a tank cover at one end of the mixing tank, and a motor at the top end of the tank cover. This invention utilizes the rotation of a separating cone, under centrifugal force, to throw plastic particles falling inside onto a screen on the inner wall of the separating cone. The screen separates plastic particles of the same size onto a feeding tray. The rotation of the separating cone drives a rotating plate on the feeding tray, pushing the plastic particles of the same size onto the feeding port, where they fall into the lower half of the mixing tank for mixing. This not only ensures that the mixed plastic particles are of the same size but also improves the uniformity of the mixture. However, in the prior art, the relevant device has significant drawbacks in actual use. Specifically, when the plastic particles fall onto the feeding tray, due to the small size of the feeding port, it is difficult to achieve an ideal feeding effect when the rotating plate pushes the plastic particles out of the feeding port. This structural design prevents the plastic granules on the feeding tray from being effectively guided to the feeding port and discharged smoothly, resulting in poor overall device performance and failing to meet the demand for efficient and smooth feeding in actual production or application. Utility Model Content

[0003] The present invention aims to solve the technical problems existing in the prior art; to this end, the present invention proposes a high-speed mixer for processing modified engineering plastics.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A high-speed mixer for processing modified engineering plastics includes a mixing tank, a rotatable separating cone is provided inside the mixing tank, and a funnel is fixedly connected inside the mixing tank.

[0006] The separating cone is externally fixedly connected to multiple connecting rods, and a ball is fixedly connected to each connecting rod. An adjustable sealing body is provided at the bottom opening of the funnel, and the sealing body and the ball are used in conjunction.

[0007] As a further embodiment of this utility model: the sealing body is in the shape of a frustum, and the sealing body is adapted to the opening at the bottom of the funnel.

[0008] As a further embodiment of this utility model: a connecting plate is fixedly connected inside the mixing tank, and a bent rod is slidably connected to the connecting plate, and the bent rod is fixedly connected to the sealing body.

[0009] As a further embodiment of this utility model: a pressure plate is fixedly connected to the bent rod, and a spring is sleeved on the outer surface of the bent rod.

[0010] As a further embodiment of this utility model, the two ends of the spring are fixedly connected to the pressure plate and the connecting plate, respectively.

[0011] As a further embodiment of this utility model: a fixing plate is fixedly connected inside the mixing tank, and a mixing component is rotatably connected to the bottom of the fixing plate.

[0012] As a further embodiment of this utility model: the top of the fixing plate is inclined, and the width of the fixing plate is greater than the diameter of the bottom opening of the funnel.

[0013] As a further embodiment of this invention, one end of the bent rod is arc-shaped.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In the process of screening plastic particles using a separating cone, the ball rotates synchronously with the separating cone and squeezes the bent rod, thereby causing the sealing body to move up and down reciprocally. This results in the bottom opening of the funnel being in an intermittently open state, which not only helps all plastic particles of the same size to fall into the funnel, but also enables intermittent feeding into the mixing tank, thereby improving the mixing efficiency of plastic particles.

[0016] 2. By setting a fixing plate, this application can not only fix the mixing components, but also prevent plastic particles from falling onto the bevel gear. At the same time, setting the top of the fixing plate with a sloping shape can prevent plastic particles from accumulating on the fixing plate. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Please see Figures 1-3 As shown, this application provides a high-speed mixer for processing modified engineering plastics, including a mixing tank 1, a rotatable separating cone 2 disposed inside the mixing tank 1, and a funnel 4 fixedly connected inside the mixing tank 1;

[0025] Multiple connecting rods 5 are fixedly connected to the outside of the separating cone 2. A ball 6 is fixedly connected to each connecting rod 5. An adjustable sealing body 7 is provided at the bottom opening of the funnel 4. The sealing body 7 and the ball 6 work together. By utilizing the rotation of the separating cone 2, the centrifugal force of the separating cone 2 filters the plastic particles, throwing them out of the separating cone 2 and onto the funnel 4. During the rotation of the separating cone 2, the connecting rods 5 drive the ball 6 to rotate synchronously. When the ball 6 moves above the bent rod 9 and squeezes the bent rod 9, the bent rod 9 moves downward, and the spring 11 is compressed. Then, the bent rod 9 drives the sealing body 7 downward, so that the sealing body 7 no longer contacts the funnel 4, thus preventing leakage. The opening at the bottom of hopper 4 is in the open state. When ball 6 moves away from bent rod 9, spring 11 gradually returns to its original state, which in turn drives bent rod 9 to rise, thereby driving sealing body 7 to return to its original state, thus sealing the opening at the bottom of hopper 4. Through the cooperation between ball 6 and bent rod 9, sealing body 7 reciprocates to seal the opening at the bottom of hopper 4, thus making the opening at the bottom of hopper 4 intermittently open. This not only helps all plastic granules of the same size on hopper 4 to fall down, but also enables intermittent feeding into mixing tank 1.

[0026] The sealing body 7 is in the shape of a frustum and is adapted to the opening at the bottom of the funnel 4.

[0027] A connecting plate 8 is fixedly connected inside the mixing tank 1, and a bent rod 9 is slidably connected to the connecting plate 8. The bent rod 9 is fixedly connected to the sealing body 7.

[0028] A pressure plate 10 is fixedly connected to the bent rod 9, and a spring 11 is sleeved on the outer surface of the bent rod 9.

[0029] The two ends of the spring 11 are fixedly connected to the pressure plate 10 and the connecting plate 8, respectively.

[0030] One end of the bent rod 9 is curved.

[0031] Example 2

[0032] Based on Example 1, see Figure 2 and Figure 4 As shown.

[0033] A fixed plate 12 is fixedly connected inside the mixing tank 1. A mixing component 3 is rotatably connected to the bottom of the fixed plate 12. The mixing component 3 consists of a rotating shaft and blades. A motor 13 is fixedly connected to the outside of the mixing tank 1. A connecting shaft 14 is fixedly connected to the output end of the motor 13. The connecting shaft 14 passes through the mixing tank 1 and extends into the interior of the mixing tank 1. Bevel gears 15 are fixedly connected to both the mixing tank 1 and the rotating shaft, and the two bevel gears 15 mesh with each other. The motor 13 is electrically connected to an external power source and is controlled by an external control program. During the screening of plastic particles using the separating cone 2, the motor 13 is turned on, which drives the connecting shaft 14 to rotate. The meshing transmission between the two bevel gears 15 drives the mixing component 3 to rotate, thereby mixing the plastic particles falling into the funnel 4. The intermittent feeding of material into the mixing tank 1 through the funnel 4 can improve the mixing efficiency of the plastic particles.

[0034] The top of the fixing plate 12 is sloped, and the width of the fixing plate 12 is greater than the diameter of the bottom opening of the funnel 4. Setting the top of the fixing plate 12 in a sloped shape prevents plastic particles from accumulating on the fixing plate 12.

[0035] The working principle of this invention is as follows: By utilizing the rotation of the separating cone 2, the plastic particles are screened under the centrifugal force of the separating cone 2, and the plastic particles are thrown out of the separating cone 2 and fall onto the funnel 4. During the rotation of the separating cone 2, the connecting rod 5 drives the ball 6 to rotate synchronously. When the ball 6 moves above the bent rod 9 and squeezes the bent rod 9, the bent rod 9 moves downward, and the spring 11 is compressed. Then, the bent rod 9 drives the sealing body 7 to move downward, so that the sealing body 7 and the funnel 4 are no longer in contact. When the ball 6 moves away from the bent rod 9, the spring 11 gradually returns to its original state, which in turn causes the bent rod 9 to rise, thereby causing the sealing body 7 to return to its original state and thus sealing the opening at the bottom of the funnel 4. Through the cooperation between the ball 6 and the bent rod 9, the sealing body 7 reciprocates in sealing the opening at the bottom of the funnel 4, thus making the opening at the bottom of the funnel 4 intermittently open. This not only helps all the plastic granules of the same size on the funnel 4 to fall down, but also enables intermittent feeding into the mixing tank 1.

[0036] During the screening of plastic particles using the separating cone 2, the motor 13 is turned on, which in turn drives the connecting shaft 14 to rotate. The meshing transmission between the two bevel gears 15 drives the mixing component 3 to rotate, thereby mixing the plastic particles falling into the funnel 4. By intermittently feeding material into the mixing tank 1 through the funnel 4, the mixing efficiency of the plastic particles can be improved.

[0037] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
