DETAILED DESCRIPTION

[0025] Below, the present invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0026] like Figure 1-8A safety interlock multifunctional shredder is shown, comprising a body 10, a shredding mechanism, a driving mechanism 20, an interlocking mechanism, a first output shaft 30 and a second output shaft 40. A first output surface 16 and a second output surface are provided on the body 10. The first output shaft 30 and the second output shaft 40 are respectively provided at two ends of the body 10. The first output shaft 30 and the second output shaft 40 are respectively pivotally connected to the first output surface 16 and the second output surface. The driving mechanism 20 is used to drive the first output shaft 30 and the second output shaft 40 to rotate. The interlocking mechanism can be used to lock the first output shaft 30 or the second output shaft 40. The shredding mechanism is used to be installed on the first output surface 16 and / or the second output surface. When the shredding mechanism is installed on the first output surface 16, the shredding mechanism can be connected to the first output shaft 30, and when the shredding mechanism is installed on the second output surface, the shredding mechanism can be connected to the second output shaft 40.

[0027] Based on the above structure, when using the safety interlock multifunctional shredder of the present invention, during shredding operation;

[0028] Specifically, the shredder mechanism can be installed on the first output surface 16, so that the shredder mechanism is connected to the first output shaft 30. At this time, the second output shaft 40 is locked by the interlocking mechanism, the driving mechanism 20 is started, the first output shaft 30 rotates, the second output shaft 40 is locked, the rotation of the second output shaft 40 is restricted, and the first output shaft 30 drives the shredder mechanism to perform the shredding operation. It should be noted that the locking referred to in this embodiment is not locking, but restricting the rotation of the first output shaft and the second output shaft, so that their power output is blocked or restricted.

[0029] When the second conveying shaft is operating, the shredding mechanism is installed on the second output surface, and the shredding mechanism is connected to the second output shaft 40. At this time, the first output shaft 30 can be locked by the interlocking mechanism, the driving mechanism 20 is started, the second output shaft 40 rotates, the first output shaft 30 is locked, the rotation of the first output shaft 30 is restricted, and the second output shaft 40 drives the cutter to perform the shredding operation. In this way, the first output shaft 30 and the second output shaft 40 can respectively perform different shredding operations. The interlocking mechanism can lock the second output shaft 40 when the first output shaft 30 is operating, and lock the first output shaft 30 when the second output shaft 40 is operating, thereby realizing safety interlocking and improving work safety.

[0030] It should be noted that the lengths of the first output shaft 30 and the second output shaft 40 are different. Under the drive of the same driving mechanism 20, the output powers are different. Of course, different powers can also be output through the driving mechanism 20 to drive the first output shaft 30 and the second output shaft 40 to rotate at different powers. The first output shaft 30 and the second output shaft 40 are connected to different chopping mechanisms to process different foods.

[0031] Preferably, in this embodiment, the interlocking mechanism comprises a first locking cover 50, a locking rod 70 and a second locking cover 60, a first locking hole is provided on the first output surface 16, and a second locking hole is provided on the second output surface. Specifically, a first locking column 71 is provided at one end of the locking rod 70, and a second locking column 72 is provided at the other end of the locking rod 70, and the first locking column 71 can extend from the first locking hole, and the second locking column 72 can extend from the second locking hole.

[0032] In addition, the first locking cover 50 can be sealed on the first output surface 16. When the first locking cover 50 is sealed on the first output surface 16, the first locking column 71 can be withdrawn from the first locking hole, and at this time, the second locking column 72 is driven to extend from the second locking hole. The second locking cover 60 is provided with a positioning hole, which is used to correspond to the second locking hole; the second locking column 72 can be inserted into the positioning hole when the positioning hole corresponds to the second locking hole, so that the second locking cover 60 is sealed on the second output surface.

[0033] On the basis of this structure, when the first output shaft 30 is operating, the second locking cover 60 can be slid on the second output surface so that the positioning hole on the second locking cover 60 corresponds to the second locking hole on the second output surface, and the second locking column 72 on the locking rod 70 extends from the second locking hole and is inserted into the positioning hole. At this time, the second locking cover 60 can cover the second output shaft 40. At this time, the tool is connected to the first output shaft 30, the driving mechanism 20 is started, the first output shaft 30 can rotate, and the rotation of the second output shaft 40 can be restricted by the second locking cover 60.

[0034] When the second output shaft 40 is operating, the first locking cover 50 can be sealed on the first output surface 16. At this time, the first locking column 71 on the locking rod 70 can extend from the first locking hole, and the second locking column 72 can be withdrawn from the second locking hole. The second locking cover 60 can slide to expose the second output shaft 40, and the first output shaft 30 can be sealed by the first locking cover 50. At this time, the tool is connected to the second output shaft 40, the driving mechanism 20 is started, the second output shaft 40 rotates, and the rotation of the first output shaft 30 can be restricted by the first locking cover 50.

[0035] In this way, the first locking cover 50 and the second locking cover 60 cooperate with the up and down movement of the locking rod 70 to achieve safety interlocking.

[0036] Preferably, a safety lock 11 and a first elastic component 15 may be provided on the first output surface 16, one end of the safety lock 11 being pivotally connected to the first output surface 16, and the other end of the safety lock 11 being rotatable toward or away from the first lock hole. The first elastic component 15 may provide a first elastic stress, under which the installation lock may rotate toward the first lock hole. After the installation lock rotates toward the first lock hole, the first locking column 71 may be pressed to make the first locking column 71 withdraw from the first lock hole. In addition, the first lock cover 50 is used to be rotatably installed on the first output surface 16, and the first lock cover 50 is provided with a pushing portion 52, and when the first lock cover 50 rotates, the pushing portion 52 may push the installation lock to rotate away from the first lock hole.

[0037] In the initial state, the safety lock 11 can be installed to cover the first lock hole under the first elastic stress provided by the first elastic component 15. At this time, the first locking column 71 of the lock rod 70 cannot extend from the first lock hole, and the second locking column 72 at the other end of the lock rod 70 extends from the second lock hole. When locking the first output shaft 30, the first lock cover 50 is pivoted on the first output surface 16, and the first lock cover 50 is rotated. The push part 52 on the first lock cover 50 can push the safety lock 11 to rotate during the rotation process, driving the safety lock 11 away from the first lock hole. At this time, the first locking column 71 on the lock rod 70 can extend from the first lock hole, and the second locking column 72 can withdraw from the second lock hole, so that the second lock cover 60 is unlocked. The first lock cover 50 is also covered on the first output surface 16.

[0038] In order to lock the first locking cover 50 more securely on the first output surface 16, a first buckle 51 may be provided on the first locking cover 50, and a second buckle 161 may be provided on the first conveying surface. When the first locking cover 50 rotates, the first buckle 51 is engaged with the second buckle 161, and the connection structure is stable.

[0039] Preferably, a second elastic component 14 is provided on the body 10, and the second elastic component 14 is used to provide a second elastic stress for moving the locking rod 70 toward the first locking hole.

[0040] A slide rail may also be provided on the machine body 10, and the locking rod 70 may be slidably matched with the slide rail. Thus, when the locking rod 70 moves up and down, the locking rod 70 may slide in the slide rail to guide it to move up and down stably.

[0041] Preferably, the machine body 10 is provided with a first touch switch 12 and a second touch switch 13, and the lock rod 70 is provided with a first avoidance position 73 and a second avoidance position 74. When the second locking column 72 extends into the second lock hole, the first touch switch 12 can correspond to the first avoidance position 73. When the first locking column 71 extends into the first lock hole, the second touch switch 13 can correspond to the second avoidance position 74. The first touch switch 12 and the second touch switch 13 are both used to control the start and stop of the driving mechanism 20.

[0042] In this way, when the first output shaft 30 is locked, the first locking column 71 can extend from the first locking hole, at which time the second touch switch 13 corresponds to the second avoidance position 74, and the first touch switch 12 is staggered from the first avoidance position, that is, the operator can operate the second touch switch 13 to start the drive mechanism 20. Similarly, when the second output shaft 40 is locked, the second locking column 72 can extend from the second locking hole, at which time the first touch switch 12 corresponds to the first avoidance position 73, and the second touch switch 13 is staggered from the second avoidance position 74, and the operator can start the drive mechanism 20 by correspondingly operating the first touch switch 12, and in this way, it is convenient to start and stop the drive mechanism 20.

[0043] Preferably, the above-mentioned chopping mechanism includes a first chopping knife 80 and a first container 200. The above-mentioned first container 200 is detachably mounted on the first output surface 16. The first chopping knife 80 is detachably connected to the first output shaft 30. The first container 200 can be a juice cup or other food container, and the first chopping knife 80 can be a blade for chopping juice.

[0044] Of course, the above-mentioned shredding mechanism also includes a second shredding knife 90 and a second container 300. The second container 300 is detachably mounted on the second output surface, and the second shredding knife 90 is detachably connected to the second output shaft 40. The second container 300 can be used as a grinding cup, and the second shredding knife 90 can be used as a grinding knife to realize the crushing, grinding and powdering of granular or blocky dry hard foods such as peanuts, coffee beans, soybeans, and medicinal materials.

[0045] It should be noted that the chopping mechanism in this embodiment is such that different chopping knives correspond to different containers to cut different ingredients, and the specific selection is made according to actual needs.

[0046] Preferably, the driving mechanism 20 includes a bidirectional motor, which can be directly purchased from the market. The working principle and structure of the motor can be directly known to those skilled in the art from the prior art, and will not be described in detail here.

[0047] Of course, the driving mechanism 20 can also be realized by using two motors.

[0048] For those skilled in the art, various other corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all of these changes and deformations should fall within the protection scope of the claims of the present invention.
