SUMMERY OF THE UTILITY MODEL

Based on this, it is necessary to provide a full-automatic grinding appearance to solve the problems that the tool changing process is complicated and time-consuming and the working efficiency is affected when the existing grinding appearance is operated.

The technical problem to be solved by the application is realized by the following structure: the full-automatic grinding instrument comprises a grinding cup positioning plate, a positioning counter bore, a foot column hole, a grinding cup, a foot column, a cup cover, a positioning hole, a cutter hanging pin shaft, a cutter bar positioning shaft, a cutter hanging groove, an arc guide inclined plane, a vertical groove, a main blade, an auxiliary blade, a spacer, a fastening screw, a cutter bar, a guide conical surface, a clamping guide sleeve, a guide conical surface, a clamping hole, an electric main shaft and a pneumatic pressing mechanism. The bottom of the full-automatic grinding instrument is provided with a grinding cup positioning plate. The positioning plate is provided with a plurality of positioning counter bores for mounting the grinding cups. The edge of the counter bore is provided with a foot post hole, and a foot post of the grinding cup is inserted into the foot post hole. The grinding cup and the cup cover are connected through threads.

The center of the cup cover is provided with a positioning hole, and two or more cutter hanging grooves are symmetrically distributed on the end surface of the positioning hole on the cup cover. Two vertical grooves are symmetrically distributed on the inner wall of the positioning hole on the cup cover, and an arc guide inclined plane is arranged between the cutter hanging groove and the vertical groove on the end surface of the positioning hole. Two cutter hanging pin shafts are symmetrically arranged on the outer circle of the cutter bar positioning shaft in the direction vertical to the axis. The lower part of the cutter is provided with a cutter bar positioning shaft. The lower part of the positioning shaft is provided with a main blade, a spacer, an auxiliary blade and a fastening screw. The upper part of the cutter is a cutter bar, and the front end of the cutter bar is a guiding conical surface. The cutter arbor passes through the centre gripping hole and presss from both sides on the electricity main shaft. The outside of the clamping hole is provided with a clamping guide sleeve, and the lower end of the clamping guide sleeve is provided with a guide conical surface.

The working principle of the patent is as follows: the bottom of the full-automatic grinding instrument is provided with a grinding cup positioning plate. The positioning plate is provided with a plurality of positioning counter bores for mounting the grinding cups. The edge of the counter bore is provided with a foot column hole, the diameter of the positioning counter bore is slightly larger than the outer diameter of the grinding cup, and the grinding cup can be easily placed in the positioning counter bore. After the grinding cup is placed in the positioning counter bore, the grinding cup is slightly rotated to enable the foot columns at the bottom of the grinding cup to fall into the foot column holes. Before the grinding cup is placed on the positioning plate, firstly, the grinding cutter body is hung on the inner hole of the cup cover manually. Then the cup cover is screwed on the grinding cup, and the cutter bar is inserted into the positioning hole of the cup cover when the cutter is hung. The cutter bar is pushed until the cutter bar positioning shaft enters the positioning hole of the cup cover, the cutter body is rotated to align the vertical groove with the cutter hanging pin shaft, the pin shaft enters the vertical groove, and the cutter body is pushed to move forward along the vertical groove.

When the cutter hanging pin shaft comes out from the other end of the vertical groove, the cutter body is rotated to enable the cutter hanging pin shaft to fall into the cutter hanging groove. The cutter bar can reliably stand upright in the cup cover positioning hole by means of self weight and cannot fall off. After all grinding cups are placed, the electric spindle and the pneumatic pressing mechanism are firstly moved to the upper part of the grinding cups when the grinding cups start to work. The pneumatic pressing mechanism moves downwards to tightly press the cup cover, and then the electric spindle moves downwards to approach the cutter bar. Firstly, the guide conical surface at the lower end of the clamping guide sleeve and the guide conical surface at the top end of the cutter bar are firstly contacted together, and the cutter bar can easily enter the electric main shaft clamping hole under the combined action of the guide conical surface and the guide conical surface. When the cutter bar enters the electric main shaft clamping hole for a certain distance, the cutter body is firmly clamped by the clamping hole. Then the electric main shaft clamps the cutter bar to move upwards, so that the hanging pin shaft is separated from the hanging cutter groove.

At the moment, the tool hanging pin shaft is arranged right above the tool hanging groove, and the electric spindle rotates for a certain angle to enable the tool hanging pin shaft to deviate from the position right above the tool hanging groove. Then the electric main shaft drives the cutter to move downwards to enable the cutter hanging pin shaft to fall on the arc guide inclined plane, the arc guide inclined plane can pull the cutter hanging pin shaft along with the downward movement of the cutter to enable the cutter rod to rotate while moving downwards, and finally the cutter hanging pin shaft can fall into the vertical groove along the arc guide inclined plane. Then the cutter bar continues to move downwards until the cutter hanging pin shaft is separated from the vertical groove, and simultaneously the cutter bar positioning shaft is completely separated from the cup cover positioning hole. At the moment, the cutter bar is not bound by the cutter hanging groove, the vertical groove and the cup cover positioning hole, the electric spindle drives the cutter bar to rotate at a high speed, the cutter bar rotates along with the electric spindle and moves downwards until the bottom of the cup, and all materials in the cup are ground.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1, 2, 3, and 4, the full-automatic grinder 100 is provided with a positioning plate 600 at the bottom thereof. The positioning plate 600 has a plurality of positioning counter bores 610 for mounting grinding cups, and the edge thereof has a pedestal hole 611. Locating counterbore 610 has a diameter slightly larger than the outer diameter of grinding cup 301. Grinding cup 301 may be easily placed into locating counterbore 610. After grinding cup 301 is placed in positioning counterbore 610, grinding cup 301 is rotated slightly so that leg 302 at its bottom falls into leg hole 611. Before the grinding cup 301 is placed on the positioning plate 600, the grinding cutter body is manually hung on the positioning hole 310 of the cup cover 300. The cap 300 is screwed onto the grinding cup 301, and the cutter bar 110 is inserted into the positioning hole 310 of the cap when the cutter is hung. The cutter bar 110 is pushed until the cutter bar positioning shaft 210 enters the positioning hole 310 of the cup cover, the cutter body is rotated to align the vertical groove 311 with the cutter hanging pin shaft 211, and the cutter hanging pin shaft 211 enters the vertical groove 311 and pushes the cutter body to move forward along the vertical groove 311.

When the knife hanging pin shaft 211 comes out from the other end of the vertical slot 311, the knife body is rotated to enable the knife hanging pin shaft 211 to fall into the knife hanging slot 312, and the knife rod 110 can reliably stand upright in the positioning hole 310 of the cup cover by virtue of self weight and cannot fall off. After all of the grinding cups 301 are placed, the electric spindle 510 and the pneumatic pressing mechanism 400 are moved to the upper side of the grinding cups 301 when the operation is started. The pneumatic pressing mechanism 400 first moves downward to press the cap 300 tightly, and then the electric spindle 510 moves downward to approach the cutter bar 110. First, the guiding taper 521 of the lower end of the guide sleeve 520 and the guiding taper 111 of the top end of the tool holder 110 touch each other, and the tool holder 110 can easily enter the guiding taper 511 by the cooperation of the guiding taper 521 and the guiding taper 111. When the tool holder 110 enters the guide taper 511 by a certain distance, the guide taper 511 firmly holds the tool holder 110. The motorized spindle 510 then carries the knife bar 110 upward, disengaging the knife hooking pin shaft 211 from the knife hooking slot 312.

At this moment, the knife hanging pin shaft 211 is right above the knife hanging groove 312, and at this moment, the electric spindle 510 rotates by a certain angle so that the knife hanging pin shaft 211 deviates from the right above the knife hanging groove 312. The motorized spindle 510 then moves downward with the tool to drop the hanger pin shaft 211 onto the arc guide ramp 313. As the tool moves downward, the arc guide slope 313 pulls the knife hanging pin shaft 211 to rotate the knife holder 110 while moving downward, and finally the knife hanging pin shaft 211 falls into the vertical slot 311 along the arc guide slope 313. The knife bar 110 continues to move downward until the knife hanging pin shaft 211 is disengaged from the vertical slot 311 and the knife bar positioning shaft 210 is completely disengaged from the cup lid positioning hole 310. At this moment, the cutter is not bound by the hanging knife groove 312, the vertical groove 311 and the cup cover positioning hole 310 at all.

The electric spindle 510 drives the cutter bar 110 to rotate at a high speed, the cutter bar 110 rotates along with the electric spindle 510 and moves downwards until the bottom of the cup, and all materials in the cup are ground in a circulating reciprocating mode. The primary and

secondary blades

121, 122 of the lower portion of the tool bar 110 are separated by a spacer 123. The main blade 121 and the auxiliary blade 122 are arranged in a left-right distribution and vertically staggered manner. The primary and secondary blades are screwed to the bottom of the tool bar 110 by a set screw 130. The mounting structure ensures the highest grinding efficiency and the best grinding effect.

When the entire material in the grinding cup 301 is completely ground, the guiding cone 511 releases the cutter bar 110, and the electric spindle 510 moves upward to retain the cutter in the grinding cup 301. The pneumatic hold-down mechanism 400 then also moves upward away from the grinder cup lid 300. Immediately after the electric spindle 510 and the pneumatic pressing mechanism 400 move to the position right above the next grinding cup 301, a new grinding operation is started, the action flow is the same as that of the previous one, and the operation is repeated until all grinding tasks are completed. In one embodiment, each grinding cup 301 contains a separate grinding tool 100 therein without risk of cross-contamination. Meanwhile, the grinding cup 301 and the cutter 100 have the advantages of simple structure and convenience in cleaning.

The tool bar 110 is movably connected with the positioning hole 310 through the tool bar positioning shaft 210. The pneumatic pressing mechanism 400 is used for pressing the cup cover 300 and the grinding cup (301). The electric spindle 510 is provided with a clamping hole 511. The electric spindle 510 is movably connected with the tool bar 110 through a clamping hole 511. The electric spindle 510 is used to control the rotation of the tool bar 110 in the positioning hole 310 and the grinding cup 301.

In one embodiment, the cap 300 and grinding cup 301 may be threaded. In one embodiment, the cap 300 and grinding cup 301 may also be snap fit. In one embodiment, the diameter of the positioning hole 310 is larger than the diameter of the tool bar positioning shaft 210 so that the tool bar 110 can be inserted into the positioning hole 310. In one embodiment, the bottom of the grinding cup 301 is not perforated and does not require a bottom seal to avoid leakage.

In one embodiment, the vertical slots 311 are disposed on the inner wall of the positioning hole 310. In one embodiment, the number of the vertical slots 311 is not limited as long as the knife pin shaft 211 of the knife bar positioning shaft 210 can move up and down along the vertical slots 311. In one embodiment, the number of vertical slots 311 may be two. In one embodiment, the number of the vertical slots 311 may be one.

In one embodiment, the number of the cutter hooking pin shafts 211 may be two, and is disposed on an outer wall of the cutter bar positioning shaft 210. In one embodiment, the hanger pin shaft 211 may be symmetrically disposed on an outer wall of the knife bar positioning shaft 210. In one embodiment, the knife pin shaft 211 may be asymmetrically disposed on the outer wall of the knife bar positioning shaft 210, as long as the positions of the knife pin shaft 211 and the vertical slot 311 are ensured to correspond one to one.

In one embodiment, the number of knife hooking slots 312 may be the same as the number of knife hooking pin shafts 211. In one embodiment, the number of the knife hanging grooves 312 can be larger than that of the knife hanging pin shafts 211, as long as the knife bar 110 can reliably stand in the positioning hole 310 of the cup cover by self weight without falling off. In one embodiment, the intelligent control system can control the electric spindle 510 to move downwards to approach the tool holder 110, and the tool holder 110 is firmly clamped by the guiding cone 511 under the combined action of the guiding cone 521 and the guiding cone 111, so as to control the further action of the tool holder 110.

In one embodiment, a clamping guide sleeve 520 is sleeved outside the guiding conical surface 511. In one embodiment, when the electric spindle 510 moves downward to approach the tool bar 110, the guiding taper 521 at the lower end of the clamping guide 520 first contacts the guiding taper 111 at the top end of the tool bar 110, and then the tool bar 110 can easily enter the guiding taper 511 under the combined action of the guiding taper 521 and the guiding taper 111. The cutter bar 110 can easily enter the guide conical surface 511 by clamping the guide sleeve 520, so that the clamping reliability is improved.

In one embodiment, the end surface between the adjacent hanging knife slot 312 and the vertical slot 311 is an arc guide inclined surface 313, and the arc guide inclined surface 313 is guided from the hanging knife slot 312 to the vertical slot 311. The circular arc guide slope 313 enables the cutter bar 110 to rotate while moving downward through the cutter hanging pin 211, and finally the cutter hanging pin 211 falls into the vertical slot 311 along the circular arc guide slope 313. Therefore, the cutter bar positioning shaft 210 is completely separated from the positioning hole 310 of the cup cover, and the cutter is completely not limited by the hanging knife groove 312, the vertical groove 311 and the positioning hole 310. At this time, the spindle 510 drives the cutter bar 110 to rotate at a high speed, so as to grind all the materials in the grinding cup.

In one embodiment, the cutter comprises a cutter bar 110 and a blade 120. One end of the tool bar 110 is provided as a guide tapered surface 111. The insert 120 is fixed to the other end of the tool bar 110 by a fixing screw 130. The blade 120 includes a main blade 121 and a sub-blade 122 which are disposed in a staggered manner, and a spacer 123 disposed between the main blade 121 and the sub-blade 122. In one embodiment, the main blade 121 and the auxiliary blade 122 can be installed in a staggered manner from left to right and from top to bottom, and the installation structure can ensure high grinding efficiency and good grinding effect. In one embodiment, the number of blades 120 is at least one.

In one embodiment, the cutter 100 can move up and down in the cup at high speed during use, and can grind layer by layer, and the materials with frozen water content and low water content can be ground very finely. Because the cutter 100 can move up and down in the cup without the help of moisture to enable materials to roll circularly, particularly, the grinding effect of the vertically staggered installation of the left and right distribution of the main blade 121 and the auxiliary blade 122 is greatly improved, and the trouble that the grinding cannot be carried out due to less moisture in the fruit and vegetable grinding is thoroughly solved.

In one embodiment, after the entire material in the grinding cup 301 is completely ground, the intelligent control system can control the guiding cone 511 to release the cutter bar 110 and control the electric spindle 510 to move upward to retain the cutter in the grinding cup 301. At the same time, the pneumatic hold-down mechanism 400 also moves upward away from the cup lid 300 of the grinding cup. In one embodiment, the motorized spindle 510 and pneumatic clamping mechanism 400 may be controlled to move directly over the next grinding cup 301 to begin a new grinding operation.

It can be understood that the number of the positioning counter bores 610 on the positioning plate 600 is not limited, and can be selected according to actual requirements. In one embodiment, the number of locating counterbores 610 may be at least one. In one embodiment, the number of leg holes 611 in each locating counterbore 610 is the same as the number of legs 302 at the bottom of grinding cup 301. In one embodiment, the shape of the post hole 611 is not limited as long as it is ensured that the post 302 can be placed in the post hole 611. In one embodiment, the post hole 611 may be square in shape. In one embodiment, the shape of the stilt hole 611 may also be circular.
