Example 1

Referring to fig. 1 to 12, the present embodiment discloses a polishing apparatus, which includes a polishing main body 1.

As shown in fig. 1, the main polishing machine 1 includes a machine body 11 and a polishing unit 12.

As shown in fig. 1 to 8, the grinding portion 12 includes a driving mechanism 121 provided on the machine body 11, a lower grinding disc assembly 122 driven by the driving mechanism 121 to rotate, and an upper grinding disc assembly 123 mounted on the machine body 11 and located above the lower grinding disc assembly 122, wherein a grinding gap 124 is formed between the upper grinding disc assembly 123 and the lower grinding disc assembly 122, and the upper grinding disc assembly 123 is adjustable up and down along its own axis with respect to the lower grinding disc assembly 122. By adjusting the upper and lower grinding disc assemblies 123 on the machine body 11, the grinding gap 124 can be adjusted, so that the thickness of the ground powder can be adjusted to meet different user requirements. With respect to the adjustment structure of the upper grinding disc assembly 123, the following will be explained in detail, which will not be mentioned.

As shown in fig. 1 to 8, the machine body 11 is provided with a feeding channel 111, and the feeding channel 111 is communicated with the grinding gap 124. During grinding, the raw materials to be ground are discharged into the grinding gap 124 from the material inlet channel 111 for grinding, and through the material inlet channel 111, the user does not need to put the raw materials to be ground into the grinding gap 124 one by one, so that the contact between the user and the upper grinding disc assembly 123 and the lower grinding disc assembly 122 is avoided, and the user is prevented from being injured by the upper grinding disc assembly 123 and the lower grinding disc assembly 122. Wherein the ground material may be coffee beans or other material that is to be ground to a powder.

In practical use, the grinding device needs to be matched with a container, the container can be a container prepared by a user for containing ground powder, and can also be a container 2 produced by a manufacturer of the grinding device and matched with the manufacturer. Preferably, the complete receiving container 2 is produced by a manufacturer. As shown in fig. 1 to 12, the receiving container 2 is detachably connected to the bottom of the machine body 11, and the receiving container 2 is provided with a container inlet 21; when the receiving container 2 and the machine body 11 are assembled in place, the upper grinding disc assembly 123 and the lower grinding disc assembly 122 penetrate through the container inlet 21 and are contained in the receiving container 2. During grinding, the upper grinding disc assembly 123 and the lower grinding disc assembly 122 are accommodated in the accommodating container 2 and are separated from the outside, so that the upper grinding disc assembly 123 and/or the lower grinding disc assembly 122 are prevented from being touched by hands during grinding to cause injury, and the grinding safety is effectively ensured; in addition, when the grinding device is used for grinding coffee beans, ground coffee powder directly falls into the containing container 2, so that the powder pouring action is reduced; the holding container 2 can be directly disassembled, and the coffee can be brewed by using the holding container 2 without preparing a brewing container additionally.

In practical applications, the driving mechanism 121 may be a manual rocker, and the manual rocker drives the lower grinding disc assembly 122 to rotate; as shown in fig. 2, the driving mechanism 121 may also be a motor, and the lower grinding plate assembly 122 is driven to rotate by the automatic rotation of the motor.

When the driving mechanism 121 is a motor, the start and stop of the motor can be controlled by the connection of the power supply of the motor, specifically: the machine body 11 is provided with a power interface 125 for connecting an external power supply, the power interface 125 is electrically connected with the driving mechanism 121, and when the power interface 125 is powered on, the driving mechanism 121 can be started to perform a grinding action; when the polishing operation needs to be stopped, the power interface 125 is disconnected from the external power source.

Preferably, the grinding device further comprises an activation switch 126 for activating the driving mechanism 121, wherein the activation switch 126 is electrically connected with the driving mechanism 121. The start switch 126 is configured to control the motor to turn on or off when the power interface 125 is powered, that is: when the starting switch 126 is triggered to start, the motor is started to grind; when the start switch 126 is turned off, the motor is stopped to stop the polishing operation.

Preferably, to avoid the user from inadvertently activating the activation switch 126, the activation switch 126 is safely set. As shown in fig. 2 and 14, the starting switch 126 is disposed at the bottom of the main body 11 and located at the upper side of the rim of the container inlet 21 of the receiving container 2; when the container 2 is assembled with the main body 11, the edge of the container inlet 21 triggers the start switch 126. That is, the start switch 126 is triggered only after the container 2 is installed in place, and is not triggered when the container is not installed in place, so that damage caused by the fact that a user accidentally triggers and starts the grinding action is avoided.

The safety setting structure of the starting switch 126 specifically includes: as shown in fig. 2 and 14, the grinding apparatus further includes an elastic trigger mechanism 127, wherein the elastic trigger mechanism 127 includes a trigger member 1271 mounted on the machine body 11 to be movable up and down, and a first elastic member 1272 pushing down the trigger member 1271, and the trigger member 1271 is located between the start switch 126 and the rim of the container inlet 21.

When the trigger member 1271 is at the lowest position, the lower end of the trigger member is abutted against the container to prevent the container 2 from being installed in place, and the elastic force of the first elastic member 1272 is greater than the weight of the grinding machine 1 when the grinding machine is filled with the raw material to be ground; when the receiving container 2 is mounted in place, the first resilient member 1272 is compressed and the trigger member 1271 triggers the activation switch 126. The first elastic element 1272 may be a spring, a compression spring or an elastic block.

Because the elasticity of the first elastic member 1272 is greater than the weight of the grinding host 1 when the grinding host is filled with the raw materials to be ground, even if the containing container 2 is arranged below the grinding host 1, the grinding action can not be triggered and started, and the user needs to press down the grinding host 1 with force to ensure that the containing container 2 and the grinding host 1 are arranged in place, so as to trigger the starting switch 126 to start grinding. That is, the elastic trigger mechanism 127 converts the pressing action of the user into the control action of starting and stopping the grinding action, so that a control circuit of the grinding device is omitted, the grinding device is more simplified, the size of the grinding device is further reduced, and the grinding device is convenient to carry.

In this embodiment, as shown in fig. 1 and 12, the machine body 11 is provided with a feeding bin 112 for feeding the raw material to be ground, the feeding bin 112 is located above the feeding channel 111, the bottom of the feeding bin 112 is communicated with the inlet of the feeding channel 111, the machine body 11 is provided with a feeding inlet 1121 communicated with the feeding bin 112, and the feeding inlet 1121 is located above the feeding bin 112. A user puts a certain amount of raw materials to be ground into the feeding bin 112 through the feeding inlet 1121 at a time, the raw materials to be ground fall into the feeding channel 111 under the action of gravity, and then enter the grinding gap 124 to be ground, so that the raw materials to be ground at the bottom are firstly ground into powder and continuously fall into the grinding gap 124 to be ground into powder under the action of gravity, and the user is not required to repeatedly add the raw materials to be ground.

In this embodiment, as shown in fig. 2, the main body 11 further includes a feeding cover plate 113 disposed on the feeding inlet 1121, the feeding cover plate 113 is used to cover the feeding inlet 1121, and the feeding inlet 1121 can be covered by the feeding cover plate 113 to prevent other foreign matters from falling into the feeding bin 112.

Specifically, the feeding inlet 1121 is provided with a chute 114 matching with the feeding cover plate 113, as shown in fig. 2, one end of the feeding cover plate 113 is inserted into the chute 114 and can slide along the chute 114 to change the size of the communication position between the feeding inlet 1121 and the outside. In other words, the feeding cover 113 is installed at the feeding inlet 1121 through the chute 114, and the size of the feeding inlet 1121 can be changed.

In this embodiment, the drive mechanism 121 is located above the upper abrasive disc assembly 123; an output shaft 1211 of the driving mechanism 121 axially penetrates through the upper grinding disc assembly 123 and is connected with the lower grinding disc assembly 122. That is, the drive mechanism 121 of the present polishing apparatus is of an upper type, the lower disc assembly 122 rotates in response to the drive of the drive mechanism 121, and the upper disc assembly 123 is fixed to the main body 11.

Specifically, as shown in fig. 5 to 7, an end surface of the upper grinding disc assembly 123 is provided with a feeding port 1231 communicated with the feeding channel 111, a lower portion of the feeding port 1231 is communicated with the grinding gap 124, and an output shaft 1211 of the driving mechanism 121 axially penetrates through the feeding port 1231 and is connected to the lower grinding disc assembly 122. The material to be ground in the feeding channel 111 enters the grinding gap 124 from the feeding port 1231, and is ground into powder. The output shaft 1211 of the driving mechanism 121 axially penetrates through the material inlet 1231 and then is connected with the lower grinding disc assembly 122, so that the lower grinding disc assembly 122 is ensured to rotate, and interference with the upper grinding disc assembly 123, the driving mechanism 121 and the like is avoided, namely, the structure is arranged on the whole structure of the simplified grinding part 12, and normal grinding operation can be ensured.

As shown in fig. 5 to 7, a guide 1232 is disposed in the feeding port 1231 for guiding the material to be ground to flow into the grinding gap 124. The guide block 1232 facilitates the material to be ground (e.g., coffee beans) in the feeding channel 111 to enter the grinding gap 124, and also limits the flow of the material to be ground, thereby preventing too much material to be ground from entering the grinding gap 124 and hindering the rotation of the lower grinding plate assembly 122.

As shown in fig. 2 to 8, the structure of the upper grinding disc assembly 123 that can be adjusted up and down at the machine main body 11 is specifically: the upper grinding disc assembly 123 and the machine body 11 are connected by a second thread so that the upper grinding disc assembly 123 can move in its own axial direction. Through the connection and matching of the second threads, the upper grinding disc assembly 123 can be adjusted up and down on the machine main body 11 along the second threads only by rotating the upper grinding disc assembly 123, and then the size of the grinding gap 124 between the upper grinding disc assembly 123 and the lower grinding disc assembly 122 can be adjusted, so that the adjustment of the thickness of the ground powder is realized.

Specifically, the second thread includes an external thread 1233 disposed on the outer wall of the upper grinding disc assembly 123 and an internal thread 115 disposed on the inner side of the machine body 11 and matching with the external thread 1233, that is, the upper grinding disc assembly 123 can be detachably connected to the machine body 11 and can also adjust the grinding gap 124 through the mutual matching of the external thread 1233 and the internal thread 115.

In order to prevent the position of the upper grinding disc assembly 123 from changing during the grinding process after the grinding gap 124 is adjusted, the upper grinding disc assembly 123 is connected to the machine body 11 so that when the grinding gap 124 reaches a set requirement, the upper grinding disc assembly 123 is limited and fixed to avoid rotating, and the structure form thereof comprises:

as shown in fig. 2 to 4, a plurality of retractable push rods 116 are disposed on the machine body 11, and a plurality of recesses 1234 are disposed on the upper grinding disc assembly 123; when the upper grinding disc assembly 123 is connected to the machine body 11 so that the grinding gap 124 meets a set requirement, each ejector rod 116 and each recess 1234 are respectively matched to limit and fix the upper grinding disc assembly 123, thereby preventing the upper grinding disc assembly 123 from rotating. That is, the top bar 116 and the recess 1234 are engaged to limit the upper disc assembly 123 after the polishing gap 124 is adjusted, so as to prevent the upper disc assembly 123 from rotating, thereby preventing the vertical position of the upper disc assembly 123 from changing, and further preventing the polishing gap 124 from changing.

Specifically, the grinding device further includes a second elastic member 117 sleeved on the top rod 116, as shown in fig. 2 to 4, the second elastic member 117 pushes the top rod 116 against the upper grinding disc assembly 123, one end of the top rod 116 contacting the recess 1234 is a rounded end 1161, and the shape of the recess 1234 is matched with the rounded end 1161. Because the end of the top rod 116 is the rounded end 1161, and the shape of the recess 1234 is matched with the rounded end 1161, when the user needs to adjust the grinding gap 124, the user only needs to twist the upper grinding disc assembly 123 to slide the top rod 116 off from the recess 1234, so that the position of the upper grinding disc assembly 123 can be adjusted in the longitudinal direction, and further the grinding gap 124 can be adjusted, and in the adjusting process, if the top rod 116 falls into the recess 1234 again under the elastic force of the second elastic member 117, the upper grinding disc assembly 123 is limited again. The second elastic element 117 may be a spring, a compression spring, or an elastic block.
