Description

Technical Field

[0001] The utility model relates to the technical field of hard ice machines, in particular to a start-stop locking device for a hard ice machine. Background Art

[0002] Italian single cylinder hard ice machine is a device specially used for making Italian hard ice. It uses the technology of controlling temperature and water flow to make the ice cream form a hard texture during the freezing process. Compared with ice making machines, Italian hard ice machine pays more attention to the taste and texture of ice cream. It is usually used in occasions with high requirements for ice cream quality, such as high-end bars, restaurants, etc.

[0003] During the operation of the Italian single-cylinder hard ice machine, when it is necessary to open the upper protective cover for feeding, although the agitator has stopped working before feeding, due to its internal mechanism and physical inertia, the agitator will continue to rotate for a period of time. This continuous inertial rotation will cause the ice cream ingredients, mixed liquid or other materials in the agitator to accidentally splash outside the machine, causing unnecessary damage to the surrounding environment and facilities. Before opening the protective cover for feeding, it is necessary to ensure that the agitator has completely stopped rotating. Although this can improve the safety of operation, it will affect the work efficiency. Therefore, a start-stop locking device for a hard ice machine is proposed to address the above problems.

When the staff puts the raw materials and other materials into the mixing cylinder 2, the scraper 5 mixes them. When it is necessary to continue to open the protective cover 7 to continue feeding, the staff rotates the handle 13 so that the handle 13 drives the stop block 12 to rotate on the rotating rod 11.

When the contact switch 1 15 and the contact switch 2 16 are not in the fitted state, the transmission assembly 3 will be in the power-off state, and the rotational force provided to the rotating shaft 4 will stop. Under the action of the trigger, when the staff turns the handle 13, the contact switch 2 16 will be moved away from the release switch 1 at the same time, so that the staff can automatically cut off the power supply of the agitator when opening the protective cover 7, which can ensure that the protective cover 7 will not contact the rotating scraper 5 in the powered state when it is opened, thereby enhancing safety.

[0026] The deceleration member includes a handle 19; the top of the protective cover 7 is fixedly connected to the handle 19; the top of the handle 19 is provided with a square groove 2014; the bottom of the square groove 2014 is slidably connected to a round rod 21, and one end of the round rod 21 passes through the handle 19 and the protective cover 7; one end of the round rod 21 is fixedly connected to a trigger rod 22; a spring is fixedly connected between the trigger rod 22 and the square groove 2014; the other end of the round rod 21 is fixedly connected to a resistance cap 23; the resistance cap 23 matches the rotating shaft 4; when working, the trigger rod 22 slides in the square groove 2014, so that the sliding of the trigger rod 22 drives the resistance cap 23 on the round rod 21 to move, and when the staff turns the handle 13, the trigger rod 22 can be pressed to drive the resistance cap 23 to cover the top of the rotating shaft 4, so that the friction between the resistance cap 23 and the rotating shaft 4 is generated, the inertial rotation of the rotating shaft 4 is slowed down, the rotation of the rotating shaft 4 is stopped in advance, and the working efficiency is improved.

[0027] The trigger member includes a pressing block 24; a slide groove 25 is provided on the side wall of the stop block 12; a slider 26 is slidably connected to the groove wall of the slide groove 25; a spring is fixed between the slider 26 and the slide groove 25; a pressing block 24 is fixed to the side wall of the slider 26; the pressing block 24 matches the contact block 18; when working, the slider 26 slides in the slide groove 25, and when the spring elastic force between the slider 26 and the slide groove 25 is greater than the spring elastic force between the contact switch 2 16 and the groove 14, when the staff turns the handle 13, the handle 13 will drive the pressing block 24 to squeeze the contact block 18, so that the contact block 18 drives the contact switch 2 16 to slide in the groove 14, thereby making the contact switch 2 16 away from the contact switch 1 15, cutting off the rotation power of the agitator, and when the handle 13 continues to rotate, the slider 26 will slide in the slide groove 25 to prevent the pressing block 24 from hindering the rotation of the handle 13.

[0028] Both ends of the rotating rod 11 are provided with sliding grooves 27; the groove wall of the sliding groove 27 is slidably connected with a trapezoidal block 28; a spring is fixedly connected between the trapezoidal block 28 and the sliding groove 27; the side wall of the receiving block 10 is provided with a pair of clamping grooves 29; the clamping grooves 29 match the trapezoidal block 28; when working, the trapezoidal block 28 slides in the sliding groove 27, and when the spring at the trapezoidal block 28 is greater than the sum of the elastic forces of the slider 26 and the spring at the contact switch, when the staff turns the handle 13, the sliding block on the rotating rod 11 After the groove 27 is rotated to correspond to the slot 29, the trapezoidal block 28 will enter the slot 29 through the elastic force of the spring, thereby limiting the rotation of the handle 13. When the force applied by the staff to rotate the handle 13 reaches a certain level, the inclined surface of the trapezoidal block 28 will retract into the sliding groove 27 after squeezing the groove wall of the slot 29, thereby releasing the limiting effect of the handle 13 and preventing the handle 13 from returning under the action of gravity after the staff rotates the handle 13. It can also avoid accidentally touching the handle 13 during normal times and causing the machine to stop working.

[0029] The inner wall edge of the resistance cap 23 is chamfered; during operation, the chamfer on the resistance cap 23 serves as a positioning aid, making it easier for the resistance cap 23 to smoothly insert the top end of the rotating shaft 4 .

[0030] The working principle is that the transmission component 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the scraper 5 to rotate. The transmission component 3 is a prior art, which provides a rotating force for the rotating shaft 4. When the staff puts the raw materials and other materials into the mixing cylinder 2, the scraper 5 mixes them. When it is necessary to continue to open the protective cover 7 to continue feeding, the staff turns the handle 13 to make the handle 13 drive the block 12 to rotate on the rotating rod 11. After the block 12 rotates, the limiting state of the protrusion 8 on the protective cover 7 is released. At this time, the staff can open the protective cover 7 on the mixing cylinder 2. Through the effect of the deceleration member, the speed at which the rotating shaft 4 stops rotating can be accelerated before the staff opens the protective cover 7, thereby improving the working efficiency. By contacting the switch 16 in the groove 1 4, when the contact block 18 is pressed, the contact block 18 will drive the contact switch 2 16 on the extension rod 17 to move downward. When the contact switch 1 15 and the contact switch 2 16 are not in the fitted state, the transmission component 3 will be in the power-off state, and the rotation force provided to the rotating shaft 4 will stop. Under the action of the trigger member, when the staff turns the handle 13, the contact switch 2 16 will be moved away from the release switch 1, so that the staff can automatically cut off the rotation power of the agitator when opening the protective cover 7, which can ensure that the protective cover 7 will not contact the scraper 5 rotating in the powered state when it is opened, thereby enhancing safety. The trigger rod 22 slides in the square groove 2014, so that the sliding of the trigger rod 22 drives the resistance cap 23 on the round rod 21 to move, and during the working When the operator turns the handle 13, the trigger rod 22 can be pressed to drive the resistance cap 23 to cover the top of the rotating shaft 4, so that the friction between the resistance cap 23 and the rotating shaft 4 is generated, the inertial rotation of the rotating shaft 4 is slowed down, the rotation of the rotating shaft 4 is stopped in advance, and the work efficiency is improved. When the slider 26 slides in the slide groove 25, and the spring elastic force between the slider 26 and the slide groove 25 is greater than the spring elastic force between the contact switch 2 16 and the groove 14, when the operator turns the handle 13, the handle 13 will drive the pressing block 24 to squeeze the contact block 18, so that the contact block 18 drives the contact switch 2 16 to slide in the groove 14, thereby making the contact switch 2 16 away from the contact switch 1 15, cutting off the rotation power of the agitator, and when the handle 13 continues to rotate, the slider 2 6 will slide in the slide groove 25 to prevent the pressing block 24 from hindering the rotation of the handle 13. The trapezoidal block 28 slides in the sliding groove 27. When the spring at the trapezoidal block 28 is greater than the sum of the elastic forces of the slider 26 and the spring at the contact switch, when the staff turns the handle 13, the sliding groove 27 on the rotating rod 11 rotates to correspond to the card slot 29, and the trapezoidal block 28 enters the card slot 29 through the elastic force of the spring, which has a limiting effect on the rotation of the handle 13. When the force applied by the staff to rotate the handle 13 reaches a certain level, the inclined surface of the trapezoidal block 28 will retract into the sliding groove 27 after squeezing the groove wall of the card slot 29, which will release the limiting effect of the handle 13 and prevent the handle 13 from returning under the action of gravity after the staff turns the handle 13.It can also prevent the machine from stopping due to accidental touching of the handle 13. The chamfer on the resistance cap 23 can assist in positioning, making it easier for the resistance cap 23 to smoothly insert the top end of the rotating shaft 4.
