TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic production equipment, specifically is a kind of anti-blocking subassembly of feeding port of mixing machine. BACKGROUND

[0002] Mixing machine is mainly suitable for the batching, mixing, coloring and drying of various resins, and is widely used. The feeding methods of mixing machine mainly include screw feeding and spring feeding. Compared with spring feeding, screw feeding is more widely used, and it can be applied to raw materials of various shapes and sizes.

[0003] The feeding port of mixing machine is generally conical with a large upper part and a small lower part. The screw feeding can continuously feed the raw materials into the feeding port of mixing machine, and the state of raw materials is gelatinous, which has strong adhesion. The existing anti-blocking subassembly of feeding port of mixing machine can clean the raw materials adhered in the feeding port by rotating vertical scraper, but when the gelatinous raw materials fall into the feeding port, they will also adhere to the vertical scraper and accumulate more easily with cooling. Therefore, frequent cleaning is required. SUMMARY

[0004] The utility model aims at providing an anti-blocking subassembly of feeding port of mixing machine to solve the problem of raw material accumulation and blockage in the middle of feeding port caused by continuous raw materials.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides an anti-blocking subassembly of feeding port of mixing machine, which comprises a feeding hopper arranged on a mixing machine and a feeding port arranged on the feeding hopper for raw material input. The anti-blocking subassembly of feeding port of mixing machine further comprises:

[0007] A shaft sleeve fixed to the top of the feeding hopper.

[0008] A cleaning shaft sleeve arranged in the shaft sleeve.

[0009] A driving part arranged on the top of the feeding hopper, which is used to drive the cleaning shaft to rotate.

[0010] An upper support fixed transversely on the shaft sleeve.

[0011] An upper support ring fixedly sleeved on the outside of the upper support.

[0012] A lower support fixed transversely on the bottom end of the shaft sleeve.

[0013] A lower support ring fixedly sleeved on the outside of the lower support.

[0014] A plurality of spiral scrapers arranged between the upper support ring and the lower support ring, the spiral scrapers being used to scrape off the raw materials adhered to the conical arc surface in the feeding hopper.

[0015] Further, the feeding port anti-blocking assembly of the mixing machine further comprises:

[0016] A support frame fixed between the outer portion of the shaft sleeve and the inner wall of the feeding hopper, the support frame being used to reinforce the stability of the shaft sleeve.

[0017] Further, the support frame is in a spread shape between the outer portion of the shaft sleeve and the inner wall of the feeding hopper, and the support frame is located on the side of the feeding hopper away from the feeding port.

[0018] Further, the upper support frame is located between the shaft sleeve and the lower support frame, and the height of the upper support frame is lower than the lower edge of the feeding port.

[0019] Further, the outer diameter of the upper support ring and the lower support ring is greater than or equal to half the width of the spiral scraper.

[0020] Further, one side of the spiral scraper is overlapped on the conical arc surface in the feeding hopper, and the spiral scraper is located between the inner wall of the feeding hopper and the upper support ring in the radial direction.

[0021] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0022] 1. The upper support frame and the lower support frame are circumferentially staggered, and the spiral scrapers are circumferentially equidistantly distributed. When the raw materials with adhesion fall on the spiral scrapers, the spiral scrapers are driven to revolve by the upper support frame and the lower support frame, and the raw materials on the inner wall of the feeding hopper are scraped off. The scraped raw materials extrude the raw materials on the spiral scrapers, and at the same time, the flowability and gravity of the raw materials are matched, so that the raw materials on the spiral scrapers can continuously slide off, avoiding the problem that the raw materials are easily cooled and solidified for long time on the spiral scrapers, and greatly reducing the frequency of cleaning the spiral scrapers.

[0023] 2. The upper support frame and the lower support frame are arranged above and below in the feeding hopper, and the cleaning shaft and other structures are matched. The raw materials input into the feeding hopper can be dispersed circumferentially twice, so that the raw materials can maintain good flowability and smoothness in the feeding hopper, avoiding the problem of raw material blockage due to mutual extrusion and accumulation of the raw materials after being input into the feeding hopper.

[0034] upper support 7 is transversely fixed on shaft sleeve 2.

[0035] upper support ring 6 is fixedly sleeved on the outside of upper support 7.

[0036] lower support 9 is transversely fixed on the bottom end of shaft sleeve 2.

[0037] lower support ring 8 is fixedly sleeved on the outside of lower support 9.

[0038] A plurality of spiral scrapers 10 are arranged between the upper support ring 6 and the lower support ring 8, and the spiral scrapers 10 are used to scrape off the raw materials adhered to the conical arc surface in the feeding hopper 1.

[0039] The cleaning shaft 4 is driven to rotate by the driving motor, and the rotation of the cleaning shaft 4 drives the upper support 7, the lower support 9, the upper support ring 6, the lower support ring 8 and the spiral scraper 10 to rotate synchronously in the circumferential direction, so that the upper support 7 contacts the raw materials first and disperses them in the circumferential direction, thereby avoiding the phenomenon of agglomeration and accumulation of the raw materials in the feeding hopper 1, and finally avoiding the problem of blockage of the raw materials in the feeding hopper 1. In addition, for the raw materials with certain adhesion, part of the raw materials adhered to the conical arc surface in the feeding hopper 1 can be scraped off by the spiral scraper 10 rotating in the circumferential direction, and the scraped raw materials fall into the mixer, thereby further avoiding the problem of blockage of the raw materials in the feeding hopper 1 due to accumulation of the raw materials. When the raw materials adhere to the upper support 7, the lower support 9, the upper support ring 6, the lower support ring 8 and the spiral scraper 10, the driving motor can be controlled to increase the rotational speed to increase the centrifugal force, so that the adhered raw materials fall off, thereby improving the self-cleaning effect.

[0040] In this embodiment, the feeding port anti-blocking assembly of the mixer further comprises:

[0041] The support frame 3 is fixed between the outer portion of the shaft sleeve 2 and the inner wall of the feeding hopper 1, and the support frame 3 is used to reinforce the stability of the shaft sleeve 2 and increase the structural strength of the shaft sleeve 2, thereby avoiding the problem of obvious shaking of the shaft sleeve 2 under high rotation during self-cleaning of the cleaning shaft 4, improving the safety, and avoiding damage to the structure inside the feeding hopper 1 or affecting the self-cleaning effect inside the feeding hopper 1.

[0042] In this embodiment, the support frame 3 is distributed in an eight-shaped manner between the outer portion of the shaft sleeve 2 and the inner wall of the feeding hopper 1, and the support frame 3 is located on the side of the feeding hopper 1 away from the feeding port 11. In this way, a triangular frame can be formed between the support frame 3, the shaft sleeve 2 and part of the inner wall of the feeding hopper 1, thereby improving the stability of the shaft sleeve 2 during rotation of the cleaning shaft 4, and avoiding the problem that the raw materials adhere to the support frame 3 after entering the feeding hopper 1, thereby reducing the cleaning workload and difficulty in the feeding hopper 1.

[0043] In this embodiment, the upper support 7 is located between the shaft sleeve 2 and the lower support 9, and the height of the upper support 7 is lower than the lower edge of the feeding port 11.

[0044] In the embodiment, the outer diameter of the upper support ring 6 and the lower support ring 8 is greater than or equal to the half of the width of the spiral scraper 10, so that when the raw materials are scattered, the raw materials can be prevented from being stuck between the upper support ring 6 or the lower support ring 8 and the inner wall of the feeding hopper 1 when sliding along the inner wall of the feeding hopper 1, so as to avoid the accumulation of raw materials in the feeding hopper 1 or affect the normal feeding of the raw materials.

[0045] The spiral scraper 10 is overlapped on the conical arc surface in the feeding hopper 1, and the spiral scraper 10 is located between the inner wall of the feeding hopper 1 and the upper support ring 6 in the radial direction, so that when the spiral scraper 10 is rotated circumferentially by the cleaning shaft 4, one side of the spiral scraper 10 is attached to the conical inner wall of the feeding hopper 1, which effectively prevents the raw materials from adhering to the inner wall of the feeding hopper 1 and accumulating, and the spiral scraper 10 is driven to revolve by the upper support 7 and the lower support 9, and the raw materials on the inner wall of the feeding hopper 1 are scraped off, the scraped raw materials are pressed to flow downward on the spiral scraper 10, and at the same time, the raw materials on the spiral scraper 10 can continuously slide down by the flowability of the raw materials and the action of gravity, so as to avoid the problem that the raw materials stay on the spiral scraper 10 for a long time and are easily cooled and solidified, reduce the amount of residual raw materials on the spiral scraper 10, greatly reduce the frequency of cleaning the spiral scraper 10, and reduce the difficulty of cleaning.

[0046] Working principle: before feeding, the driving motor can be started in advance, so that the driving motor drives the cleaning shaft 4 to rotate, and the rotation of the cleaning shaft 4 drives the upper support 7, the lower support 9, the upper support ring 6, the lower support ring 8 and the spiral scraper 10 to rotate synchronously, so that the upper support 7 contacts the raw materials first and scatters them circumferentially, so as to avoid the phenomenon that a large amount of raw materials are gathered in a certain place in the feeding hopper 1, and finally cause the problem of raw material blockage in the feeding hopper 1, and for raw materials with certain adhesion, the raw materials adhered to the conical arc surface in the feeding hopper 1 can be scraped off by the circumferentially rotating spiral scraper 10, and the scraped raw materials fall into the mixer, so as to further avoid the problem of blockage in the feeding hopper 1 due to raw material accumulation, and when the upper support 7, the lower support 9, the upper support ring 6, the lower support ring 8 and the spiral scraper 10 are adhered with raw materials, the centrifugal force can be increased by controlling the driving motor to increase the rotating speed, so that the adhered raw materials are detached, and the raw materials can smoothly enter the mixer.
