Description

Technical Field

[0001] The present application relates to the technical field of lemon tampers, and in particular to a mechanism for driving a lemon tamping rod to lift and lower, and a lemon tamper using the mechanism. Background Art

[0002] The lemon machine can efficiently extract the juice from lemons by pounding. In addition to lemons, it can also process other fresh fruits. Compared with manual juicing, the lemon machine can extract juice more fully, reduce waste, and save a lot of time.

[0003] During the pounding process, food processing machines such as lemon machines usually use an integrated lifting mechanism to control the position of the beating rod. The integrated lifting mechanism can drive the beating rod to move up and down, so that the beating rod can beat the lemons or other fresh fruits, and then extract the juice of the lemons or other fresh fruits. However, during the pounding process, this integrated design drives the beating rod downward to beat the lemons or other fruits and vegetables. The reaction force caused by the pounding will suddenly impact the machine, causing the integrated lifting mechanism and the base on which the integrated lifting mechanism is installed to shake and rebound, thereby affecting the service life of the machine. Summary of the Invention

[0004] In order to reduce the impact of the reaction force of the lemon machine on the machine during the pounding process, the present application provides a mechanism for driving the lemon machine beating rod to rise and fall and a lemon pounder using the same.

[0005] In the first aspect, the present application provides a mechanism for driving the lifting and lowering of a lemon machine beating stick, which adopts the following technical solution:

[0006] A mechanism for driving a lemon machine pounding rod to rise and fall includes a base, a driving module provided on the base, an output end of the driving module connected to the bottom of the slider, one side of the slider being slidably connected to the side wall of the base, the driving module being used to drive the slider to reciprocate up and down, a fixed plate provided on the top surface of the slider, a connecting piece provided on the top surface of the fixed plate, one end of the connecting piece passing through both the fixed plate and the top surface of the slider, the top of the connecting piece extending beyond the top surface of the fixed plate, a spring sleeved on the outer wall of the portion of the connecting piece extending beyond the fixed plate, and a tamping rod connected to one end of the fixed plate away from the slider.

[0007] By adopting the above technical solution, the shaker is placed at the bottom of the tamping rod, the driving module is started, the driving module drives the slider to do reciprocating motion up and down, the slider drives the fixed plate and the tamping rod to do reciprocating motion up and down, and the tamping rod beats the lemon. When the tamping rod is beating, an upward reaction force is generated, and the reaction force is transmitted to the fixed plate through the tamping rod, and the fixed plate then transmits the reaction force to the spring. The downward force provided by the spring during the force process is gradual. The spring can gradually increase the force instead of suddenly generating a large force, thereby reducing sudden impacts, and further reducing the shaking and rebound of the tamping drive module and the base, reducing the impact of the reaction force on the lemon machine during the beating process.

[0008] Preferably, the driving module includes a driving member, a crank arm and a connecting rod. The driving member is installed at the bottom of the base, the output end of the driving member is assembled with the bottom of the crank arm, the bottom of the connecting rod is axially connected to the top of the crank arm, and the top of the connecting rod is axially connected to the bottom of the slider.

[0009] By adopting the above technical solution, the driving member is started, and the driving member drives the crank arm to perform circular motion. When the crank arm moves downward, the crank arm pulls the connecting rod to move downward, and the connecting rod drives the slider to move downward along the guide rail. When the crank arm moves upward, the crank arm pushes the connecting rod to move upward, and the connecting rod pushes the slider to move upward, thereby driving the slider to perform reciprocating motion up and down.

[0010] Preferably, a tamping hammer head is detachably connected to the bottom of the tamping rod.

[0011] By adopting the above technical solution, under the action of the tamping hammer head, the force area when beating the lemon can be increased, so that more juice can be extracted when the tamping hammer head beats the lemon, thereby reducing the time for lemon juice extraction and improving the efficiency of the automatic lemon beating machine in extracting juice. The tamping rod and the tamping hammer head are detachably connected, which makes it convenient for users to replace tamping hammer heads of different specifications according to different scenarios.

[0012] Preferably, the fixing plate includes a fixing portion and a connecting portion, the fixing portion and the connecting portion form a "T"-shaped structure, the fixing portion is connected to the top surface of the slider, one end of the connecting portion is fixed to the middle of one side of the fixing portion, and the connecting portion is connected to the tamping rod at one end away from the fixing portion.

[0013] By adopting the above technical solution, the fixing part and the connecting part form a "T"-shaped structure, thereby increasing the contact area between the fixing part and the slider, and further increasing the connection stability between the fixing part and the slider. At the same time, the connecting part is narrower than the fixing part, so that the connecting part plays the role of connecting the tamping rod, and also reduces the use of materials. It can also reduce the overall weight of the fixing plate and reduce the weight of the support of the tamping drive assembly. Moreover, the connecting part is fixed in the middle of the fixing part, and the weight borne by the connecting part can be evenly distributed on the fixing part.

[0014] In a second aspect, the present application provides a lemon tamper, comprising a frame, a cup seat connected to the bottom of the frame, and the cup seat is located at the bottom of the tamper.

[0015] By adopting the above technical solution, the shaker is placed in the cup holder cavity, thereby limiting the bottom of the shaker. During the process of squeezing the lemon in the shaker, the displacement or tipping of the shaker can be reduced.

[0016] Preferably, the cup holder is rotatably connected to the frame, and a rotating cup driving assembly is assembled on the bottom of the cup holder, and the rotating cup driving assembly is used to drive the cup holder to rotate.

[0017] By adopting the above technical solution, the rotating cup drive assembly can drive the cup base to rotate, thereby realizing the function of mashing the lemon while rotating the cup, so that the lemon is pounded more evenly.

[0018] Preferably, a lifting drive assembly is provided on a side of the base away from the slider, and the lifting drive assembly is used to drive the base to move downward or upward.

[0019] By adopting the above technical solution, under the action of the lifting drive assembly, the lifting drive assembly can drive the base to move downward or upward. When the lemon is squeezed, the lifting drive assembly is started, and the lifting drive assembly drives the base to move upward, thereby increasing the distance between the squeezing hammer head and the cup holder, so that the squeezing hammer head can be away from the shaker cup cavity, which is convenient for the user to take the shaker cup away. Correspondingly, it is also convenient for the user to place the shaker cup in the cup holder before using the lemon squeezer. When the lemon needs to be squeezed, the lifting drive assembly is started, and the lifting drive assembly drives the base to move downward until the squeezing hammer head is located in the shaker cup cavity, which is convenient for the squeezing hammer head to pound the lemon.

[0020] Preferably, a first position detection photoelectric switch is installed on a side of the base close to the slider, and the first position detection photoelectric switch is used to detect whether the slider is at the lowest point.

[0021] By adopting the above technical solution, when tamping, the first position detection photoelectric switch can detect whether the slider is at the lowest position. Under the action of the first position detection photoelectric switch, it can be detected in real time whether the tamping process of the tamping hammer head is proceeding smoothly. If the tamping cannot be completed, it can be reminded in the first time, which is convenient for the user to discover the fault and perform repairs in the first time.

[0022] Preferably, a second position detection photoelectric switch is installed on the side of the base close to the slider, and the second position detection photoelectric switch is located on the top of the first position detection photoelectric switch. The second position detection photoelectric switch is used to detect whether the slider is at the highest position.

[0023] By adopting the above technical solution, the second position detection photoelectric switch can detect whether the slider is at the highest position. Under the action of the second position detection photoelectric switch, the slider is at the highest point when the tamping starts and ends, so that the lemon can be tamped better. At the same time, more space is provided between the tamping hammer head and the cup holder, making it easier for users to take and place the shaker.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Place the shaker cup at the bottom of the tamping rod, start the drive module, the drive module drives the slider to do reciprocating motion up and down, the slider drives the fixed plate and the tamping rod to do reciprocating motion up and down, the tamping rod beats the lemon, when the tamping rod is beating, it will generate an upward reaction force, the reaction force is transmitted to the fixed plate through the tamping rod, and the fixed plate then transmits the reaction force to the spring. The downward force provided by the spring during the force process is gradual, and the spring can gradually increase the force instead of suddenly generating a large force, thereby reducing sudden impacts, thereby reducing the shaking and rebound of the tamping drive module and the base, and reducing the impact of the reaction force on the lemon machine during the beating process.

[0026] 2. Start the driving part, which drives the crank arm to perform circular motion. When the crank arm moves downward, the crank arm pulls the connecting rod downward, and the connecting rod drives the slider to move downward along the guide rail. When the crank arm moves upward, the crank arm pushes the connecting rod upward, and the connecting rod pushes the slider upward, thereby driving the slider to perform up and down reciprocating motion.

In the embodiment of the present application, the drive member is a motor 21, which is installed on the inner side of the bottom of the base 1. The output end of the motor 21 moves through the side wall of the base 1, the output end of the motor 21 is fixed to the bottom of the crank arm 22, the bottom of the connecting rod 23 is axially connected to the top of the crank arm 22, and the top of the connecting rod 23 is axially connected to the bottom of the slider 24. A guide rail is fixed to the side of the base 1 close to the tamping drive assembly 2, the guide rail is arranged in the vertical direction, and the inner side of the slider 24 is slidably connected to the guide rail.

[0033] Reference Figure 1 and Figure 2 , start the motor 21, the motor 21 drives the crank arm 22 to perform circular motion. When the crank arm 22 moves downward, the crank arm 22 pulls the connecting rod 23 to move downward, and the connecting rod 23 drives the slider 24 to move downward along the guide rail. When the crank arm 22 moves upward, the crank arm 22 pushes the connecting rod 23 to move upward, and the connecting rod 23 pushes the slider 24 to move upward, thereby driving the slider 24 to perform up and down reciprocating motion.

[0034] The cam 33 is fixed to the top of the cam 33 and is secured to the cam 33 by a spring 32 which is secured to the cam 33 by a spring 32 which is secured to the cam 33 and is secured to the cam 33 by a spring 32 which is secured to the cam 33 and is secured to the cam 33 by a spring 32 which is secured to the cam 33 and is secured to the cam 33 by a spring 32 which is secured to the cam 33 and is secured to the cam 33 by a spring 32 which is secured to the cam 33 and is secured to the cam 33 by a spring 32 which is secured to the cam 33 and is secured to the cam 33 by a spring 32 which is secured to the cam 33 and is secured to the cam 33

[0035] A tamping rod 41 is fixed to one end of the connecting portion 34 away from the fixing portion 33. The tamping rod 41 is vertically arranged and located at the bottom of the connecting portion. A tamping hammer head 42 is threadedly connected to the bottom of the tamping rod 41. Under the action of the tamping hammer head 42, the force area when beating the lemon can be increased, so that more juice can be extracted when the tamping hammer head 42 beats the lemon, thereby reducing the time for extracting lemon juice and improving the efficiency of the automatic lemon beating machine in extracting juice. The tamping rod 41 and the tamping hammer head 42 are threadedly connected, thereby improving the convenience of disassembly and assembly between the tamping rod 41 and the tamping hammer head 42, making it convenient for users to replace tamping hammer heads 42 of different specifications according to different scenarios.

[0036] Reference Figure 2 , the shaker is placed at the bottom of the tamping hammer head 42, the motor 21 is started, the connecting rod 23 drives the slider 24 to do reciprocating motion up and down, the slider 24 drives the fixed plate 3 and the tamping rod 41 to do reciprocating motion up and down, and the tamping rod 41 drives the tamping hammer head 42 to pound the lemon. When the tamping hammer head 42 is pounding, an upward reaction force is generated, and the reaction force is transmitted to the tamping rod 41 through the tamping hammer head 42, and the tamping rod 41 transmits the reaction force to the fixed plate 3, and the fixed plate 3 then transmits the reaction force to the spring 32. The downward force provided by the spring 32 during the force-bearing process is gradual, and the spring 32 can gradually increase the force instead of suddenly generating a large force, thereby reducing the situation of sudden impact, and then reducing the shaking and rebound of the tamping drive assembly 2 and the base 1, reducing the impact of the reaction force on the machine during the pounding process of the lemon machine.

[0037] In a second aspect, an embodiment of the present application further discloses a lemon pounder, comprising the above-mentioned mechanism for driving the lemon pounding rod to rise and fall.

[0038] Reference Figure 2A lemon pounder includes a frame 5, the bottom of the frame 5 is rotatably connected to a cup holder 61, the cup holder 61 is located at the bottom of the pounding hammer head 42, and the shaker is placed in the cavity of the cup holder 61, thereby limiting the bottom of the shaker. The bottom of the cup holder 61 is equipped with a rotating cup drive assembly 62, which can drive the cup holder 61 to rotate, thereby realizing the function of squeezing the lemon while rotating the cup, so that the lemon is pounded more evenly.

[0039] A lifting drive assembly 7 is provided on the side of the base 1 away from the slider 24. Under the action of the lifting drive assembly 7, the lifting drive assembly 7 can drive the base 1 to move downward or upward. When the lemon is squeezed, the lifting drive assembly 7 is started, and the lifting drive assembly 7 drives the base 1 to move upward, thereby increasing the distance between the squeezing hammer head 42 and the cup holder 61, so that the squeezing hammer head 42 can be away from the shaker cup cavity, which is convenient for the user to take the shaker cup away. Correspondingly, it is also convenient for the user to place the shaker cup in the cup holder 61 before using the lemon squeezer. When the lemon needs to be squeezed, the lifting drive assembly 7 is started, and the lifting drive assembly 7 drives the base 1 to move downward until the squeezing hammer head 42 is located in the shaker cup cavity, which is convenient for the squeezing hammer head 42 to pound the lemon.

[0040] Reference Figure 1 and Figure 2 A first position detection photoelectric switch 81 and a second position detection photoelectric switch 82 are installed on the side of the base 1 close to the slider 24. The first position detection photoelectric switch 81 is located at the bottom of the second position detection photoelectric switch 82. When the lifting drive assembly 7 lowers the base 1 to the lowest point, the tamping hammer head 42 is in the pounding process, and the slider 24 is at the lowest point and is at the same height as the first position detection photoelectric switch 81. The slider 24 is at the highest point and is at the same height as the second position detection photoelectric switch 82.

[0041] The lifting drive assembly 7 lowers the base 1 to the lowest point. When the tamping hammer head 42 hammers downward, the first position detection photoelectric switch 81 detects whether the slider 24 has reached the lowest point. If the first position detection photoelectric switch 81 does not detect that the slider 24 has reached the lowest point within one second, the system will determine that the tamping drive assembly 2 is stuck or malfunctioning, and the tamping hammer head 42 will have difficulty in continuing to hammer the lemon. After that, the motor 21 will automatically reverse and try to drive the tamping hammer head 42 to hammer downward again. If the tamping hammer head 42 successfully hammers the lemon, the first position detection photoelectric switch 81 will detect that the slider 24 has reached the lowest point. If the slider 24 reaches the lowest point, the tamping program continues to run until it is completed and stops. If the first position detection photoelectric switch 81 still does not detect that the slider 24 has reached the lowest point after trying again, the motor 21 is reversed again. After repeating the attempt four times, the tamping hammer head 42 still cannot complete the hammering, then the tamping is stopped, the machine automatically resets to the initial state, and an alarm is sounded. Therefore, under the action of the first position detection photoelectric switch 81, whether the tamping process of the tamping hammer head 42 is smooth can be detected in real time. If the tamping cannot be completed, a reminder can be given at the first time, which is convenient for the user to find the fault and perform maintenance at the first time.

[0042] The second position detection photoelectric switch 82 detects whether the slider 24 is at the highest position. When the machine is started, if the second position detection photoelectric switch 82 does not detect that the slider 24 is at the highest point, the motor 21 will drive the slider 24 to move upward until the second position detection photoelectric switch 82 detects that the slider 24 is at the highest point. Moreover, when the tamping is completed, the second position detection photoelectric switch 82 must detect that the slider 24 is at the highest position before the tamping stops. Under the action of the second position detection photoelectric switch 82, the slider 24 is at the highest point when the tamping starts and ends, so that the lemon can be tamped better. At the same time, more space is provided between the tamping hammer head 42 and the cup holder 61, making it easier for the user to take and place the shaker.

[0043] The above are all preferred embodiments of the present application. These embodiments are only explanations of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be covered within the scope of protection of the present application.
