TECHNICAL FIELD

[0001] The utility model belongs to the technical field of discharge structure, and particularly relates to a forming template of a granulator. BACKGROUND

[0002] The number and size of the die holes of the template determine the discharge capacity of the granulator, thereby controlling the production capacity. In the existing granulator template, for example, a current granulator has 120 die holes with a hole diameter of 2.8 mm, and all the 120 die holes are in an open state in full-load production, at which time the processing capacity is 2.5 tons / hour. When it is necessary to produce materials of other specifications, the feed amount of the template will change due to the different physical and chemical properties of the materials, and the template corresponding to the feed amount needs to be replaced, which is very cumbersome to operate. SUMMARY

[0003] The utility model aims at overcoming the defects in the prior art and providing a forming template of a granulator.

[0004] To achieve the above-mentioned purpose, the utility model discloses a forming template of a granulator, which comprises a template main body and at least one plug, a plurality of die holes are arranged on the template main body, the die holes comprise coaxial and sequentially arranged feed holes, diameter-reducing holes and discharge holes, the radial dimension of the diameter-reducing holes gradually decreases from the feed holes to the discharge holes, the radial dimension of the feed holes is not less than the radial dimension of the inlet of the diameter-reducing holes, the radial dimension of the discharge holes is not greater than the radial dimension of the outlet of the diameter-reducing holes, the plug comprises coaxial and sequentially arranged front plugs, middle plugs and rear plugs, the plug is inserted into the die hole, the side wall of the front plug is in contact with the inner side wall of the discharge hole, the side wall of the middle plug is in contact with the inner side wall of the diameter-reducing hole, the side wall of the rear plug is in contact with the inner side wall of the feed hole, and the length of the front plug is not more than the depth of the discharge hole.

[0005] Preferably, the length of the front plug is equal to the depth of the discharge hole.

[0006] Preferably, the length of the plug is equal to the depth of the die hole.

[0007] Preferably, a groove is arranged at the inlet position of the die hole on the template main body, and the inlet of the die hole is located at the bottom of the groove.

[0008] Preferably, the plurality of die holes are divided into a plurality of die hole groups each comprising at least two die holes.

[0009] The die holes of one die hole group are arranged at intervals along the radial direction of the template main body, and the grooves corresponding to all the die holes of one die hole group are communicated.

[0010] Preferably, the grooves corresponding to each die hole group are independently arranged.

[0011] Preferably, all grooves corresponding to the group of mold holes are connected.

[0012] Preferably, multiple sets of die holes are arranged at equal intervals along the circumferential direction.

[0013] Preferably, the front end face of the front plug is spherical.

[0014] Preferably, the template body is provided with multiple connection holes.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The die cavity of the template includes a radially decreasing diameter orifice. When the material passes through the die cavity, the radially decreasing diameter orifice can better control the flow of the material, so that it forms a more uniform shape at the die cavity outlet, reducing particle deformation and irregularity, and improving the molding effect.

[0017] The plugs are specifically configured to include a front plug, a middle plug, and a rear plug arranged coaxially and sequentially. The plugs are inserted into the mold hole, with the side wall of the front plug contacting the inner side wall of the discharge hole, the side wall of the middle plug contacting the inner side wall of the narrowing hole, and the side wall of the rear plug contacting the inner side wall of the feed hole. When the plugs are inserted into the mold hole, the side wall of the plugs contacts the inner side wall of the mold hole, thereby blocking the mold hole. At this time, the number of mold holes in the open state on the template changes, that is, the output of the template changes. When it is necessary to adjust the output of the template, the corresponding number of plugs can be inserted on the template. There is no need to disassemble and replace the entire template. The operation is simple and highly versatile.

[0018] Since the die hole is divided into a diameter reduction hole, the plug is not only fixed to the template by friction with the inner wall of the die hole, but also fixed by the limiting of the diameter reduction hole by the middle plug, so the assembly is reliable.

[0019] The length of the front plug does not exceed the depth of the discharge hole. This prevents the front plug from protruding from the template and interfering with the cutter outside the template, thus affecting the normal use of the equipment. Attached Figure Description

The plug is inserted into the mold hole 110, and the side wall of the front plug 210 is in contact with the inner side wall of the discharge hole 113, the side wall of the middle plug 220 is in contact with the inner side wall of the diameter-reducing hole 112, and the side wall of the rear plug 230 is in contact with the inner side wall of the feeding hole 111, that is, the shape and size of the plug are matched with the shape and size of the mold hole 110, when the plug is inserted into the mold hole 110, the side wall of the plug is in contact with the inner side wall of the mold hole 110, thereby plugging the mold hole 110, at this time, the number of mold holes 110 in the open state on the mold plate changes, that is, the discharge amount of the mold plate changes, when it is necessary to adjust the discharge amount of the mold plate, the corresponding number of plugs are inserted into the mold plate, without the need to disassemble and replace the entire mold plate, the operation is simple and the universality is high. Since the mold hole 110 is partially formed as a diameter-reducing hole 112, at this time, the plug is fixed on the mold plate by friction between the plug and the inner side wall of the mold hole 110, and the middle plug 220 limits the plug in the diameter-reducing hole 112, thereby ensuring reliable assembly.

The grooves of the die holes 110 of each die hole group plate are communicated, so that the spindle can machine the grooves at one time, and the machined die hole 110 does not need to be removed after the groove corresponding to the die hole 110 is machined, thereby reducing the machining steps and improving the machining efficiency, and in addition, the grooves of the die holes 110 of each die hole group plate are communicated, so that the grooves are larger and the plug can be taken out more easily.

[0035] In the embodiment, the grooves corresponding to each die hole group plate are separately arranged, which can avoid the problem that the size of the groove machined on the die plate main body 100 is too large and affects the strength of the die plate main body 100.

[0036] Of course, the grooves corresponding to all the die hole group plates are all communicated, so that the machining spindle can machine the grooves at one time, and the machining efficiency is higher.
