[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] There are various types of electric coffee powder tamping machines on the market. Generally, a DC reduction motor head gear meshes with a rack, and a powder hammer is installed at the bottom of the rack. The DC reduction motor drives the rack forward and reversely to carry the powder hammer up and down to achieve powder compacting. During the action, two upper and lower plastic blocks that cover the rack are also required to ensure that the rack can only move up and down in a straight line. The applicant found in the research that this type of coffee powder tamping machine is relatively expensive and noisy. In order to solve this type of technical problem, the applicant proposed a powder compacting device, including a casing, a control system is provided on one side of the powder compacting device, and a drive system is provided on the other side, wherein the drive system includes an electric push rod, the electric push rod is connected to the control system, and a powder compacting head is connected to the end of the electric push rod, and the control system controls the electric push rod to rise and fall, driving the powder compacting head to move along the height direction of the powder compacting device.
[0025] In this embodiment, the powder pressing device designs the control system and the driving system independently, which can ensure that the driving system has sufficient space in the casing and facilitate the maintenance of the control system. The driving system uses an electric push rod to solve the problem of noise after a period of use caused by the rack and pinion transmission in the prior art. At the same time, the use of an electric push rod is easy to standardize, reduce costs, and avoid customization.
[0026] It should be noted that the electric push rod in this application is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. After the motor is decelerated by the worm gear, it drives a pair of lead screw nuts to convert the rotational motion of the motor into linear motion, and the push rod action is completed by the forward and reverse rotation of the motor.
[0027] In order to arrange the electric push rod reasonably, the applicant has improved the casing, wherein the casing 2 includes a base, a plurality of support plates and a top plate connected in sequence, a bracket 7 is installed on the support plate, and the bracket 7 is located below the electric push rod 5, thereby allowing the electric push rod 5 to have an independent area layout, and it is independent and away from the control system.
[0028] Based on the design of the housing 2, a sensor 4 can be further added in the present invention, wherein, due to the design of the housing 2 and the internal layout (i.e., the arrangement of the control system and the drive system inside the housing 2), a variety of layout methods are provided for the sensor 4.
[0029] As one of the preferred layout forms, the sensor 4 is mounted on the bracket 7 , and the control system is connected to the sensor 4 .
[0030] As another preferred layout form, the sensor 4 may also be installed on the housing 2 , and the control system is connected to the sensor 4 .
[0031] It should be noted that the sensor 4 is used to sense the position of the powder, that is, no matter whether it is installed on the bracket 7 or the housing 2, the sensor 4 is located near the travel path or positioning point of the powder, so that the position of the powder can be collected and fed back to the control system.
[0032] As a further solution, the powder pressing head 6 includes a fixed end, a connecting end and a pressing end which are connected in sequence, wherein the fixed end is fixedly matched with the electric push rod 5, and the area of the fixed end is smaller than the area of the pressing end.
[0033] It can be understood that after the end of the electric push rod 5 is matched with the fixed end, the powder pressing head 6 can be integrated with the electric push rod 5, so that when the electric push rod 5 performs linear motion, the powder pressing head 6 can be driven to perform linear motion. The end of the electric push rod 5 and the fixed end can be matched by rotation or plug-in, which is not particularly limited here.
[0034] As a preferred technical solution, the area of the connecting end gradually increases from the fixing end to the pressing end, and the area of the connecting end is not greater than the area of the pressing end.
[0035] It can be understood that since the fixed end is tightly connected to the electric push rod 5 and the force required for powder compression is not large, the diameter of the main part of the electric push rod 5 is relatively small. Since the area of the powder may be large during powder compression, the connecting end is designed in the present application to gradually increase in area from the fixed end to the pressing end, and for the sake of reliability and uniformity of force, the area of the connecting end is controlled not to be larger than the area of the pressing end. In this way, it can be ensured that when the electric push rod 5 drives the powder pressing head 6 to contact the powder, it can grind the powder evenly and efficiently to avoid damage to the powder pressing head 6.
[0036] Furthermore, the surface of the pressing end has a corrugated structure.
[0037] It can be understood that when the surface of the pressing end has a corrugated structure, the contact area with the powder can be further increased, and the corrugated structure can also make the surface of the pressing end rougher than the flat surface, which is more conducive to the rapid grinding of the powder.
[0038] Preferably, the control system includes a power supply 1 and a control board 3 , the power supply 1 is fixed to the base, the power supply 1 is connected to the control board 3 , and the control board 3 is located above the power supply 1 .
[0039] It can be understood that since the power supply 1 has a large volume, the base can support the power supply 1. By placing the control board 3 above the power supply 1, the height of the control board 3 can be increased. In this way, when a fault occurs, the maintenance personnel do not need to bend down for maintenance.
[0040] The utility model also proposes a coffee powder tamping machine, comprising the above-mentioned powder tamping device and an operating panel 8, wherein the operating panel 8 is connected to a control system, and preferably further comprises a push rod, wherein a powder bowl is provided on the push rod.
[0041] The working process of the coffee powder pressing machine in this embodiment is described in detail below.
[0042] The power supply is started by controlling the operation panel, and the control panel starts working when it receives the start signal. At this time, the powder bowl 10 filled with powder 9 can be placed on the push rod 7 manually or by machine, and the powder bowl 10 is pushed to a predetermined position. When the sensor 4 detects that the powder bowl 10 is approaching, the control panel 3 issues a command after receiving the proximity information of the sensor 4. At this time, the electric push rod 5 drives the powder pressing head 6 to automatically perform the powder pressing action after being energized; after a certain period of powder pressing, the electric push rod drives the powder pressing head 6 to return to the initial position after the powder pressing is completed. At this time, the powder pressing head is away from the powder bowl 10, and the powder bowl 10 is pulled out by the push rod to obtain the required powder.
[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
