Description

Technical Field

[0001] The invention relates to the technical field of ice cream making auxiliary devices, in particular to an ice cream freezing tunnel. Background Art

[0002] In the existing ice cream freezing tunnel, multiple ice cream cones are conveyed to the ice cream freezing tunnel by a conveyor belt for freezing. However, in order to minimize the emission of cold air on both sides of the ice cream freezing tunnel, the two sides are sealed by a sealed door. The conveyor belt is generally set in the ice cream freezing tunnel. At this time, the ice cream cone can only be placed at the outermost position of the conveyor belt at a time. After the ice cream cone is placed, the conveyor belt continues to convey, so that the ice cream cone is placed at the next position of the conveyor belt. This is not very safe and convenient. In addition, the multiple ice cream cones placed in the ice cream freezing tunnel will be frozen by the cold wind from one direction. Such a freezing method is not efficient enough.

[0003] To this end, we designed an ice cream freezing tunnel that can move multiple cylinders placed in the ice cream freezing tunnel to the outside world, making it easier to place multiple ice cream cones from the outside world in multiple cylinders more efficiently and safely. After being transferred to the ice cream freezing tunnel, the ice cream can be placed at a high place and rotated in a circle, making the ice cream cones more efficiently frozen.

[0046] Key References Figure 1 , Figure 2 , Figure 3 , Figure 4 The freezing tunnel frame 1 is in the shape of a frame with openings on both sides. An air outlet 2 is provided at the top of the freezing tunnel frame 1. Sealed doors 4 that can be pushed and pulled back and forth are provided on both sides of the freezing tunnel frame 1 to seal both sides of the freezing tunnel frame 1. The freezing tunnel frame 1 is made of a transparent material.

[0047] First supporting legs 6 are fixedly mounted on both sides of the bottom of the freezing tunnel frame 1 .

[0048] A plurality of cold air outlet devices 3 are fixedly installed in the freezing tunnel frame 1 , and the plurality of cold air outlet devices 3 all blow cold air in the same direction and on one side, so as to freeze the ice cream liquid in the ice cream freezing cylinder 26 .

[0049] Support platforms 5 are provided on both the left and right sides of the freezing tunnel frame 1 , and the support platforms 5 are not in contact with the freezing tunnel frame 1 and the sealing door 4 .

[0050] A slide plate 14 is fixedly connected transversely in the freezing tunnel frame 1, and a limiting slide plate 15 is slidably connected to the top of the slide plate 14. The lowest horizontal height of the limiting slide plate 15 is the same as the highest horizontal height of the supporting platform 5, so that the limiting slide plate 15 can slide smoothly to the top of the supporting platform 5.

[0051] A plurality of ice cream cone placing mechanisms are fixedly installed on the top of the limiting slide 15, which are divided according to the middle part of the limiting slide 15. The plurality of ice cream cone placing mechanisms placed on the left side of the middle part of the limiting slide 15 are the left plurality of ice cream cone placing mechanisms, and the plurality of ice cream cone placing mechanisms placed on the right side of the middle part of the limiting slide 15 are the right plurality of ice cream cone placing mechanisms. An ice cream freezing cone 26 can be placed on each ice cream placing mechanism.

[0052] The inner bottoms on both sides of the freezing tunnel frame 1 are both limitedly rotatably connected with the first spline shafts 11, the outer walls of the two first spline shafts 11 are limitedly slidably connected with the first spline sleeves 21, and the outer walls of the first spline sleeves 21 are fixedly connected with the first gear 20.

[0053] Key References Figure 3 Motors 10 are fixedly mounted on the outer bottoms of the left and right sides of the freezing tunnel frame 1, and the power output ends of the two motors 10 are respectively connected to the two first spline shafts 11.

[0054] Key References Figure 3 The outer bottoms of the left and right sides of the freezing tunnel frame 1 are fixedly installed with electric telescopic rods 7, the telescopic ends of the electric telescopic rods 7 are placed in the freezing tunnel frame 1, and the telescopic ends of the electric telescopic rods 7 are fixedly installed with first bearing seats 9, and the first bearing seats 9 are slidably connected in the first limiting chute 8 provided on the inner wall of the freezing tunnel frame 1. The first spline sleeve 21 is rotatably connected in the first bearing seat 9. Starting the electric telescopic rod 7 can make the first spline sleeve 21 move up and down.

[0055] Key References Figure 5 The outer wall of the limiting slide plate 15 is evenly arranged with multiple teeth 16 in the horizontal direction. When the first spline shaft sleeve 21 descends to the preset position, the first gear 20 meshes with the teeth 16. The two motors 10 are started synchronously and in the same direction so that the limiting slide plate 15 and the multiple ice cream placement mechanisms can be moved outside the freezing tunnel frame 1. That is, the multiple ice cream placement mechanisms on the left side can be completely placed on the left side of the freezing tunnel frame 1 and remain stable when placed on the left side of the freezing tunnel frame 1, and the multiple ice cream placement mechanisms on the right side can be completely placed on the right side of the freezing tunnel frame 1 and remain stable when placed on the right side of the freezing tunnel frame 1.

[0056] At this time, the operator can place multiple ice cream freezing cylinders 26 loaded with ice cream liquid in the multiple ice cream placing mechanisms on the left side at one time, and then place multiple ice cream freezing cylinders 26 loaded with ice cream liquid in the multiple ice cream placing mechanisms on the right side at one time, thereby facilitating the operator to quickly load multiple ice cream freezing cylinders 26 loaded with ice cream liquid into the freezing tunnel frame 1, so that multiple ice cream liquids can be frozen efficiently, and the loading process is relatively safe and convenient.

[0057] Embodiment 2: Based on Embodiment 1, a technical means is added to facilitate placement of multiple ice cream freezing cylinders 26 and facilitate rapid freezing of multiple ice cream freezing cylinders 26 in the freezing tunnel frame 1.

[0058] Key References Figure 6 The ice cream cone placing mechanism includes a cylinder 25, each cylinder 25 and the limiting slide 15 are connected with a threaded rod 35 for limited rotation, the outer wall of the threaded rod 35 is fixedly connected with a third gear 36, the outer wall of the threaded rod 35 is threadedly connected with a second limiting slide 34, the rear bottom of the cylinder 25 is fixedly connected with a back plate 48, the second limiting slide 34 is connected to the second limiting slide groove 37 on the back plate 48 in an up-and-down limited sliding connection, one side of the second limiting slide 34 is fixedly connected with a first limiting slide 33, the first limiting slide 33 is connected to the groove at the bottom of the cylinder 25 in an up-and-down limited sliding connection, the top of the first limiting slide 33 is fixedly connected with a third bearing seat 28, and the third bearing seat 28 is connected to the inner wall of the cylinder 25 in a limited sliding connection.

[0059] Key References Figure 6 The bottom of each cylinder 25 is connected to the limiting slide plate 15 for limited rotation with a third spline sleeve 30, the inner limiting sliding connection of the third spline sleeve 30 is connected to the third spline shaft 29, the top of the third spline shaft 29 is fixedly connected to the bottom axis of the top plate 27, and the outer wall of each third spline sleeve 30 is fixedly connected to a second gear 31, and the second gear 31 is meshed with the corresponding third gear 36.

[0060] Key References Figure 6 The third spline shaft 29 is connected to the third bearing seat 28 for limited rotation.

[0061] Key References Figure 3 , Figure 4 and Figure 6 The outer wall of each third spline sleeve 30 is fixedly connected with a second toothed belt gear 32, the left and right tops of the limiting slide plate 15 are connected with a first rotating column 17 for limited rotation, and the tops of the two first rotating columns 17 are fixedly connected with a first toothed belt gear 19.

[0062] Key References Figure 3 , Figure 4 and Figure 6 A sixth bearing seat 43 is fixedly connected to the front middle part of the limiting slide plate 15, and the sixth bearing seat 43 is slidably connected to the second rotating column 44 in the upper limit position. A third toothed belt gear 45 and a fourth toothed belt gear 46 are fixedly connected to the outer wall of the second rotating column 44 near the top. The third toothed belt gear 45, the multiple second toothed belt gears 32 on the left, and the first toothed belt gear 19 on the left are jointly covered with a toothed belt 18, so that the first toothed belt gear 19 on the left, the multiple second toothed belt gears 32 on the left, and the third toothed belt gear 45 rotate synchronously in a circle.

[0063] Key References Figure 3 , Figure 4 and Figure 6 The fourth toothed belt gear 46, the plurality of second toothed belt gears 32 on the right side, and the first toothed belt gear 19 on the right side are also covered with a toothed belt 18, so that the fourth toothed belt gear 46, the plurality of second toothed belt gears 32 on the right side, and the first toothed belt gear 19 on the right side rotate synchronously. The fourth toothed belt gear 46, the first toothed belt gear 19, and the third toothed belt gear 45 have the same diameter, and the diameters of the fourth toothed belt gear 46, the first toothed belt gear 19, and the third toothed belt gear 45 are larger than the diameter of the second toothed belt gear 32, so that the toothed belt 18 stably drives the plurality of second toothed belt gears 32 to rotate.

[0064] When the second rotating column 44 is rotated, multiple top plates 27 and ice cream freezing cylinders 26 can be moved up and down in a circle, and the top plates 27 and ice cream freezing cylinders 26 in a circle only rise a short distance. The top of the top plate 27 is provided with a notch, so that the ice cream freezing cylinder 26 is stably placed thereon.

[0065] When multiple top plates 27 are placed on the left outer side or right outer side of the freezing tunnel frame 1, the second rotating column 44 is rotated to lift the top plate 27 to a higher position, so as to facilitate the placement of multiple ice cream freezing cylinders 26, and then the ice cream freezing cylinder 26 is moved downward in a circle, so that the ice cream freezing cylinder 26 can continue to be mixed and stirred, and it is convenient to check whether there are foreign objects on the outer periphery of the ice cream freezing cylinder 26. When there are foreign objects, the multiple ice cream freezing cylinders 26 are stopped from being lowered into the cylinder body 25. When multiple ice cream freezing cylinders 26 are placed in the cylinder body 25, it is possible to prevent people from accidentally touching the ice cream freezing cylinder 26 and causing the ice cream liquid to spill, and the ice cream freezing cylinder 26 placed in the cylinder body 25 will not pollute the freezing tunnel frame 1, but will only spill the ice cream liquid into the cylinder body 25, and the cylinder body 25 can be moved to the outside, which is convenient for cleaning the spilled ice cream liquid.

[0066] After the plurality of ice cream freezing cylinders 26 are stably and safely placed in the cylinder 25, the plurality of ice cream freezing cylinders 26 are transferred to the freezing tunnel frame 1. When the ice cream freezing cylinder 26 is placed in the freezing tunnel frame 1 for freezing operation, the ice cream freezing cylinder 26 can be lifted to the top of the cylinder 25, and can rotate in a circle at the top, so that the plurality of cold air outlet devices 3 that discharge cold air on one side quickly freeze the ice cream liquid in the plurality of ice cream freezing cylinders 26. This rapid freezing method relatively more evenly freezes the ice cream liquid, making the ice cream taste better and more even. And the high degree of freezing prevents the inner wall of the cylinder 25 and the outer wall of the ice cream freezing cylinder 26 from generating ice chips, thereby hindering the removal operation of the ice cream freezing cylinder 26. The rotating downward ice cream freezing cylinder 26 allows safer downward movement into the cylinder 25, and when encountering large ice chips, it will not fall immediately, and there is a certain buffer time, which is convenient for personnel to stop the ice cream freezing cylinder 26 from falling. At this time, the ice cream freezing cylinder 26 is placed at a high place and transferred to the outside of the freezing tunnel frame 1, so that the device can freeze and transfer the ice cream freezing cylinder 26 more safely.

[0067] The other structures are the same as those of the first embodiment.

[0068] Embodiment 3: Based on the embodiment 2, a technical means is added to facilitate the top plate 27 and the ice cream freezing cylinder 26 to be placed in multiple places to rotate up and down stably and safely and to extend the service life of the device.

[0069] It should be noted that when the device is running, the wires and electrical appliances need to be kept as still as possible, which will extend the service life of the device. The motor 10 and the electric telescopic rod 7 are both kept stationary.

[0070] Key References Figure 4 The outer wall of the second rotating column 44 is connected to the fifth bearing seat 40 in a limited rotation manner, the bottom of the second rotating column 44 is fixedly connected to the fourth bevel gear 42, the left side of the fifth bearing seat 40 is fixedly connected to the fourth bearing seat 39, the inner part of the fourth bearing seat 39 is connected to the second spline sleeve 38 in a limited rotation manner, the outer wall of the second spline sleeve 38 is fixedly connected to the third bevel gear 41, and the third bevel gear 41 and the fourth bevel gear 42 are meshed with each other.

[0071] The left and right sides of the bottom of the freezing tunnel frame 1 are fixedly connected to the second bearing seats 12. The two second bearing seats 12 are jointly connected to the second spline shaft 13 for limited rotation. The second spline shaft 13 is limitedly slidably connected in the second spline shaft sleeve 38. Both ends of the second spline shaft 13 are fixedly connected to the second bevel teeth 23.

[0072] The outer walls of the two first spline sleeves 21 are both fixedly connected with first bevel teeth 22 , and the two first bevel teeth 22 can mesh with the two second bevel teeth 23 respectively.

[0073] When the first spline sleeve 21 rises to the first preset position, the first bevel teeth 22 and the second bevel teeth 23 are meshed with each other. At this time, the first gear 20 is placed on the upper side of the teeth 16 and does not mesh with the teeth 16. When the first spline sleeve 21 descends to the second preset position, the first gear 20 and the teeth 16 are meshed with each other, and the first bevel teeth 22 are placed on the lower side of the second bevel teeth 23 and do not mesh with the second bevel teeth 23.

[0074] The two motors 10 are synchronized to move in opposite directions, so that the second spline shaft 13 rotates stably, thereby achieving the operation of the plurality of top plates 27 and the ice cream freezing cylinder 26 moving up and down in a circle.

[0075] The other structures are the same as those in the second embodiment.

[0076] In this embodiment, first, the two sealing doors 4 are pushed backward so that the two sides of the freezing tunnel frame 1 remain open. The two electric telescopic rods 7 are started so that the two first spline shaft sleeves 21 move downward, and at this time, the two first gears 20 are meshed with the teeth 16. The two motors 10 are started synchronously and in the same direction so that the limit slide 15, the cylinder 25, and the top plate 27 move to one side, so that the multiple cylinders 25 and the top plates 27 on the left side are moved to the support platform 5 on the left side, and then the electric telescopic rod 7 is started so that the electric telescopic rod 7 rises. At this time, the first gear 20 is no longer meshed with the teeth 16, and the first bevel gear 22 and the second bevel gear 23 remain meshed, so that the multiple top plates 27 move upward in a circumferential manner, and the multiple ice cream freezing cylinders 26 are placed on the top of the multiple top plates 27 on the left side respectively. At this time, the top plate 27 is at the top of the cylinder 25, and it is easy and convenient to place the multiple ice cream freezing cylinders 26 on the multiple top plates 27. Then, the two motors 10 are rotated in the opposite direction so that the multiple ice cream freezing cylinders 26 are stably moved into the cylinder 25, preventing the ice cream liquid from being scattered due to accidental contact by personnel. When the ice cream freezing cylinder 26 is initially moved into the cylinder body 25, the ice cream freezing cylinder 26 rotates in a circle above the cylinder body 25, so it is easy to observe whether there is any foreign matter on the outer wall of the ice cream freezing cylinder 26. When a foreign matter is found, the motor 10 is immediately stopped and the ice cream freezing cylinder 26 is replaced to prevent the foreign matter from contaminating the device.

[0077] Similar to the above, the plurality of cylinders 25 on the right side are transferred to the support platform 5 on the right side to place the ice cream freezing cylinders 26 .

[0078] After the ice cream freezing cylinder 26 enters the cylinder 25 safely and stably, the two sealing doors 4 are closed, and the cold air outlet device is started to blow cold air into the freezing tunnel frame 1. At this time, the electric telescopic rod 7 is started so that the first gear 20 and the teeth 16 are meshed with each other, so that the ice cream freezing cylinder 26 and the top plate 27 are both placed in the freezing tunnel frame 1, and then the cylinder 25 is kept stationary. At this time, the electric telescopic rod 7 is started again so that the third bevel gear 41 and the fourth bevel gear 42 are meshed, so that the ice cream freezing cylinder 26 is placed on the top of the cylinder 25, and the ice cream freezing cylinder 26 is rotated back and forth on the top of the cylinder 25. The ice cream freezing cylinder 26 rotating in a circle is frozen more quickly under the blowing of the cold air from the one side of the cold air outlet device 3, and the frozen taste is better. At this time, the top plate 27 and the ice cream freezing cylinder 26 rotating in a circle prevent the top plate 27, the ice cream freezing cylinder 26 and the inner wall of the cylinder 25 from freezing, which makes it inconvenient to take out the ice cream freezing cylinder 26 later. When the temperature sensors 47 evenly distributed in the freezing tunnel frame 1 detect that the temperature is lower than the preset freezing temperature, the cold air is no longer blown, so that the freezing tunnel frame 1 maintains the required temperature, and then maintains the preset freezing time so that the ice cream freezing cylinder 26 is completely frozen.

[0079] After the ice cream freezing cylinder 26 is frozen, the cold air outlet device 3 is closed, and the ice cream freezing cylinder 26 is moved into the cylinder body 25, and then the multiple ice cream freezing cylinders 26 on the left are transferred to the left side of the freezing tunnel frame 1, and the multiple ice cream freezing cylinders 26 are stably and safely taken out. Then the multiple ice cream freezing cylinders 26 on the right are transferred to the right side of the freezing tunnel frame 1, and the corresponding ice cream freezing cylinders 26 are stably and safely taken out, thereby realizing efficient and safe loading of ice cream raw materials, efficient and safe ice cream freezing operations, and efficient and safe removal of finished ice cream. The ice cream freezing cylinder 26 and the top plate 27 placed at a high place and rotating back and forth in a circle will not freeze with the cylinder body 25, so that it is convenient to take out the ice cream freezing cylinder 26 safely later.

Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
