TECHNICAL FIELD

[0001] The present application relates to the technical field of foaming machine, in particular to a discharge door of a foaming machine and the foaming machine. BACKGROUND

[0002] The foaming machine needs a discharge port, which is used to discharge the foamed particles. In order to achieve complete stirring without dead angle, the inner side of the discharge door used to close the discharge port must also be set as a circular arc. In order to ensure the efficiency of discharging, the area of the discharge port must be large enough, because the material is easy to be clamped between the discharge port and the discharge door. Since the temperature of the foaming barrel is high in the working state, the clamped material is easy to be scorched, and then the material blocking occurs. The discharge door in the prior art is basically set as a square, so under the condition of ensuring the discharge area, the overall thickness of the discharge door will be thicker, so that more material is clamped between the discharge port and the discharge door, and the material blocking is more serious.

[0003] In view of the above problems, the applicant has conducted in-depth research, and thus the present application is produced. SUMMARY

[0004] The main purpose of the present application is to provide a discharge door of a foaming machine, which solves the problem that the existing discharge door of the foaming machine is thick, causing more clamped material and material blocking after being scorched.

[0005] In order to achieve the above purpose, the solution of the present application is to provide a discharge door of a foaming machine, which comprises a door body, the door body has two first straight sides parallel to the axis of the material barrel and two first arc-shaped sides perpendicular to the first straight sides; the distance between the two first straight sides is less than the length of the first straight side.

[0006] Further, the length of the first arc-shaped side is less than the length of the first straight side.

[0007] Further, the door body has a convex head extending into the discharge port of the material barrel; the convex head has an inner end facing the material barrel and an outer end facing the outside of the material barrel; the side surface of the outer end of the convex head is formed with an air groove.

[0008] Further, the air groove is formed around the side surface of the outer end of the convex head.

[0009] Further, the air groove forms a closed loop.

[0010] Further, the door body is formed with a ventilation hole communicating with the air groove.

[0011] Further, the door body further comprises a step outside the discharge port of the material barrel.

[0012] The application also provides a foaming machine, which further comprises a foaming barrel with a discharge port; the discharge port has a second straight side corresponding to the first straight side and a second arc-shaped side corresponding to the first arc-shaped side.

[0013] Further, the discharge port and the step have a gap therebetween.

[0014] Further, a plurality of guide sliding rails are further included; the guide sliding rails are arranged on both sides of the discharge port.

[0015] Further, one end of the step is further fixedly connected with a first bearing plate, and a plurality of guide sliding holes corresponding to the guide sliding rails are arranged on the first bearing plate.

[0016] Further, the end of the guide sliding rail away from the discharge port is further fixedly connected with a second bearing plate; and a driving device for driving the door body is further arranged on the second bearing plate.

[0017] After the above structure is adopted, the discharge door of the foaming machine has the advantages that under the premise of ensuring that the discharge area is large enough, the original square discharge door is changed into a rectangular discharge door, that is, the length of the arc-shaped side of the original square discharge door is reduced, the length of the straight side is increased, the height of the whole discharge door is increased, the width is reduced, and thus the thickness of the whole door is reduced, and in addition, the air groove is arranged on the discharge door. Compared with the prior art, the application can reduce the clamping of the discharge door, realize almost no clamping, and reduce the situation that the clamping is burned and blocked.

[0025] In order to further explain the technical solutions of the present application, the present application is described in detail below through specific embodiments.

[0026] As shown in Figures 1-4 A discharge door of a foaming machine, comprising a door body 1, the door body 1 has two first straight sides 11 parallel to the axis of the material bucket and two first arc-shaped sides 12 perpendicular to the first straight sides 11; the distance between the two first straight sides 11 is less than the length of the first straight sides 11. By making the distance between the two first straight sides 11 of the discharge door less than the length of the first straight sides 11, the entire discharge door is in the shape of a rectangle. As shown in Figure 4 Under the premise of ensuring that the discharge area is large enough, L1 is less than L2, the thickness of the entire discharge door will be relatively small, at the same time, the contact area between the discharge door and the discharge port will be reduced, especially the contact area between the material and the edge of the discharge port is reduced, so the material clamping between the discharge door and the discharge port 21 will be reduced, thereby reducing the situation that the clamped material is burned and blocked. Since the thickness of the discharge door is reduced, the material for manufacturing the discharge door is also reduced, thereby reducing the cost.

[0027] Preferably, the length of the first arc-shaped side 12 is less than the length of the first straight side 11. When the length of the first arc-shaped side 12 is less than the length of the first straight side 11, the discharge door is in the shape of a rectangle, at this time, the thickness of the entire discharge door will be relatively reduced, the material clamping between the discharge door and the discharge port 21 will be reduced, in addition, the manufacturing material for manufacturing the discharge door can also be reduced, thereby reducing the cost.

[0028] Preferably, the door body 1 has a protrusion 13 extending into the discharge port 21 of the material bucket; the protrusion 13 has an inner end facing the inside of the material bucket and an outer end facing the outside of the material bucket; the side surface of the outer end of the protrusion 13 is formed with a gas groove 131. By blowing gas into the gas groove 131, the material clamping between the discharge port 21 and the discharge door is blown away, so that the material clamping between the discharge port 21 and the discharge door is further reduced, and almost no material clamping is achieved.

[0029] Preferably, the gas groove 131 surrounds the side surface of the outer end of the protrusion 13. When the gas groove 131 is located on the side surface of the outer end of the protrusion 13, the gas can cover the entire protrusion 13 when blowing, and the effect of blowing away the clamped material is better. The clamped material scraped to the groove on the entire circumferential surface is blown out.

[0030] Preferably, the gas groove 131 forms a closed loop. The gas grooves 131 on the four side surfaces of the outer end of the protrusion 13 are connected, forming a closed loop. The closed loop can increase the flow of gas, making it easier to blow away the clamped material. The entire circumferential surface has gas flow, and the clamped material scraped to the groove on the entire circumferential surface is blown out.

[0031] Preferably, the door body 1 has a vent 132 that communicates with the air groove 131. Air can be introduced into the air groove 131 through the vent 132.

[0032] Preferably, the door body 1 also includes a step 14 located outside the discharge port 21 of the material bucket. The step 14 can limit the movement of the door body 1.

[0033] like Figures 2-3 As shown, this invention also provides a foaming machine, which further includes a foaming tank 2 with a discharge port 21; the discharge port 21 has a second straight side 211 corresponding to and cooperating with the first straight side 11, and a second arcuate side 212 corresponding to and cooperating with the first arcuate side 12. Similarly, when the length of the second arcuate side 212 is less than the length of the second straight side 211, the entire discharge port 21 is rectangular, so the thickness of the discharge port 21 is also relatively small, thereby reducing material clamping.

[0034] Preferably, there is a gap between the discharge port 21 and the step 14. The gap between the discharge port 21 and the step 14 allows the material that has been blown away to be discharged.

[0035] Preferably, it also includes multiple guide rails 22; the guide rails 22 are arranged on both sides of the discharge port 21. The discharge gate closes and opens the discharge port 21 by moving along the guide rails 22.

[0036] Preferably, one end of the step 14 is also fixedly connected to a first bearing plate 15, and the first bearing plate 15 is provided with a plurality of guide sliding holes 151 that slide in cooperation with the guide slide rail 22. By cooperating with the guide slide rail 22 through the guide sliding holes 151, the discharge gate can be made more stable.

[0037] Preferably, a second support plate 23 is fixedly connected to the end of the guide rail 22 away from the discharge port 21; the second support plate 23 is also provided with a drive device 3 for driving the door body 1. The drive device 3 is a cylinder or a hydraulic cylinder.

[0038] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
