Description

Technical Field

[0001] This utility model relates to an apparatus for producing ice cups. Background Technology

[0002] Frozen drinks, including ice cream, are very popular in summer. Ice cream products are generally packaged in paper cups or plastic cups, as detailed in Chinese patent CN201610566876.1. However, in the high temperatures of summer, traditional paper or plastic cups cause ice cream to melt quickly due to rapid heat exchange with the outside environment, affecting its taste. Some manufacturers use frozen ice cups as containers, but these are made by filling molds with water and freezing them, resulting in ice cups that are too hard to drink. Utility Model Content

The output shaft of the lifting motor extends vertically upwards and is coaxially connected to the corresponding lead screw.

[0024] For the sake of simplicity, the device for producing ice cups described in this utility model will be referred to as "this device" in the following description.

[0025] The working process of this device is as follows:

[0026] In the initial state of this device, the sealing plate on the lower side of the feeding screw cooperates with the flared mouth at the lower part of the feeding hole, and the feeding hole is in a closed state. The first part of the ice cup punch is located inside the ice cup cavity. The movable ring on the ice cup punch and the columnar body formed by the third part cooperate with the through hole on the base. The upper side of the fourth part and the lower side of the base are left with space. At this time, the feeding screw, the upper plate of the cavity, the ice cup cavity, the through hole on the base and the ice cup punch together form a closed receiving cavity.

[0027] First, the ice slush is poured into the hopper from the opening on the upper side. Then, the lifting motor is started. Under the action of the two fourth synchronous pulleys and the third synchronous belt, the lead screws on the left and right sides of the lifting platform rotate synchronously. The lead screw nuts on the left and right sides of the lifting platform drive the entire lifting platform to move down along the slide rail. At this time, the conveying rod connected to the long strip box in the middle of the lifting platform will drive the feeding screw on its lower side to move down synchronously. The sealing plate on the lower side of the feeding screw disengages from the flared mouth at the bottom of the feeding hole, and the feeding port is in the open state. Then, the rotating motor is started. The rotating motor drives the coaxially arranged conveying rod. The other conveying rods also rotate synchronously under the coordinated action of the first synchronous pulley, the second synchronous pulley, the third synchronous pulley, the first synchronous belt, the second synchronous belt, and the corresponding tensioning pulley. Under its own gravity and the drive of the feeding screw, the ice slush in the hopper enters the corresponding feeding hole from the bottom of the hopper, and then continues to move down through the feeding screw into the receiving cavity.

[0028] Once the container is filled with ice slush, stop rotating the motor and control the lifting motor to reverse. The reverse lifting motor drives the entire lifting platform to move upward along the slide rail. At this time, the feeding rod connected to the long strip box in the lifting platform will drive the feeding screw on its lower side to move upward synchronously. The sealing plate on the lower side of the feeding screw cooperates with the flared mouth at the bottom of the feeding hole, and the feeding port returns to the closed state.

[0029] Next, the locking cylinder is activated. The piston rod of the locking cylinder pushes the locking push plate backward. The locking push plate drives the corresponding locking sliders on both sides to move backward. The wedge-shaped barbs of the locking sliders extend backward into the through groove of the corresponding locking tongue. The upper inclined surface of the wedge-shaped barb cooperates with the upper inclined surface of the through groove cavity, pushing the locking tongue upward. The locking tongue drives the ice cup punch upward to squeeze the locking mold through the rotating shaft until the upper side of the fourth part of the ice cup punch is close to the lower side of the base. At this time, the ice slush in the receiving cavity is compressed and the ice cup is formed.

[0030] After the ice cup is formed, the locking cylinder drives the ice cup punch to reset, the locking push plate disengages from the locking tongue, and then the vertical cylinder is activated to control the rotary shaft to move downward. The square slider at the end of the rotary shaft moves downward along the first slide groove, and after leaving the first slide groove, it continues to move downward into the second slide groove. The formed ice cup and the ice cup punch move downward together with the rotary shaft until they are completely separated from the ice cup die. When the slider continues to move downward to the middle of the length of the second slide groove, it stops. At this time, the tilting cylinder is activated. The tilting cylinder drives the rotary shaft to rotate 180° by rotating the second slide groove. After the formed ice cup and the ice cup punch rotate 180° together with the rotary shaft, the demolding cylinder is activated. The demolding cylinder pushes the punch ejector beam. The punch ejector beam drives the movable ring on the ice cup punch to move downward through the connecting rod, thereby demolding the formed ice cup attached to the ice cup punch. The demolded ice cup is collected by other equipment located below and sent to the next station for subsequent processing.

[0031] Finally, the demolding cylinder drives the movable ring to reset via the punch ejection beam and connecting rod. The flipping cylinder drives the rotary shaft to rotate 180° again by rotating the second slide groove. The vertical cylinder is activated to control the rotary shaft to move upward. The square slider at the end of the rotary shaft moves upward along the second slide groove. After leaving the second slide groove, it continues to move upward into the first slide groove to reset, returning to the initial state of the device. Then, the above operations are repeated for continuous production.

[0032] Advantages of this device: This device has a simple structure and produces ice cups using shaved ice as raw material. It can not only form a stable ice cup structure and be used as an ice cream container to keep the ice cream warm, but also crush the ice cream and eat it together to enhance the taste.

[0033] An adjusting screw is coaxially located on the rear side of the piston rod of the locking cylinder. By adjusting the number of turns of the adjusting screw and the nut connector, the depth of the wedge-shaped barb inserted into the locking tongue groove can be controlled, thereby controlling the extrusion stroke of the ice cup punch, that is, controlling the tightness of the pressed ice cup.

[0034] The rotating motor is located on the upper side of the box, corresponding to a material conveying rod located near the center along the left and right directions. This ensures that the load on the first and second synchronous belts on both sides is relatively balanced. Attached Figure Description

[0065] In the initial state of this device, the sealing plate 21 on the lower side of the feeding screw 2 cooperates with the flared mouth 143 at the lower part of the feeding hole 141, and the feeding hole 141 is in a closed state. The first part 41 of the ice cup punch 4 is located inside the ice cup concave mold 12. The columnar body formed by the movable ring 421 and the third part 43 on the ice cup punch 4 cooperates with the through hole 13 on the base 1, and the upper side of the fourth part 44 and the lower side of the base 1 are left with space. At this time, the feeding screw 2, the upper plate 14 of the concave mold, the ice cup concave mold 12, the through hole 13 on the base 1 and the ice cup punch 4 together form a closed receiving cavity.

[0066] First, the slush is poured into hopper 142 through the upper opening. Then, the lifting motor 72 is started. Under the action of the two fourth synchronous pulleys 712 and the third synchronous belt, the lead screws 711 on both sides of the lifting platform rotate synchronously. The lead screw nuts 713 on both sides of the lifting platform drive the entire lifting platform to descend along the slide rail. At this time, the conveying rod 81 connected to the long strip box 8 in the middle of the lifting platform will drive the feeding screw 2 on its lower side to descend synchronously. The sealing plate 21 on the lower side of the feeding screw 2 and the feeding hole 141 descend... The horn 143 of the feed inlet is disengaged, and the feed port is in an open state. Then, the rotating motor 82 is started. The rotating motor 82 drives the coaxially arranged conveying rod 81. The other conveying rods 81 also rotate synchronously under the coordinated action of the first synchronous pulley 83, the second synchronous pulley 84, the third synchronous pulley 85, the first synchronous belt, the second synchronous belt and the corresponding tensioning pulley 86. The ice slush in the hopper 142 enters the corresponding feed hole 141 from the bottom of the hopper 142 under its own gravity and driven by the feed screw 2, and then continues to go down through the feed screw 2 into the receiving cavity.

[0067] Once the cavity is filled with ice slush, stop rotating motor 82 and control lifting motor 72 to reverse. Lifting motor 72 reverses and drives the entire lifting platform to move upward along the slide rail. At this time, the feeding rod 81 connected to the long strip box 8 in the lifting platform will drive the feeding screw 2 on its lower side to move upward synchronously. The sealing plate 21 on the lower side of the feeding screw 2 cooperates with the flared mouth 143 at the lower part of the feeding hole 141, and the feeding port returns to the closed state.

[0068] Next, the locking cylinder 54 is activated. The piston rod of the locking cylinder 54 pushes the locking push plate 53 backward. The locking push plate 53 drives the corresponding locking sliders 52 on both sides to move backward. The wedge-shaped barb 521 of the locking slider 52 extends backward into the through groove 51 of the corresponding locking tongue 5. The upper inclined surface of the wedge-shaped barb 521 cooperates with the upper inclined surface of the through groove 51, pushing the locking tongue 5 upward. The locking tongue 5 drives the ice cup punch 4 to press the locking mold upward through the rotating shaft 3 until the upper side of the fourth part 44 of the ice cup punch 4 is close to the lower side of the base 1. At this time, the ice slush in the receiving cavity is compressed and the ice cup is formed.

[0069] After the ice cup is formed, the locking cylinder 54 drives the ice cup punch 4 to reset, and the locking push plate 53 disengages from the locking tongue 5. Then, the vertical cylinder 31 is activated to control the rotary shaft 3 to descend. The square slider 32 at the end of the rotary shaft 3 descends along the first slide groove 33. After leaving the first slide groove 33, it continues to descend into the second slide groove 34. The formed ice cup and the ice cup punch 4 descend together with the rotary shaft 3 until they are completely separated from the ice cup die 12. When the slider 32 continues to move downward to the middle of the length direction of the second slide groove 34, it stops. At this time, the flipping cylinder is activated. Cylinder 35, the tilting cylinder 35 drives the rotating shaft 3 to rotate 180° by rotating the second slide 34. After the formed ice cup and the ice cup punch 4 rotate 180° together with the rotating shaft 3, the demolding cylinder 6 is activated. The demolding cylinder 6 pushes the punch ejection beam 61. The punch ejection beam 61 drives the movable ring 421 on the ice cup punch 4 to move down through the connecting rod 451, thereby demolding the formed ice cup attached to the ice cup punch 4. The demolded ice cup is collected by other equipment located below and sent to the next station for subsequent processing.

[0070] Finally, the demolding cylinder 6 drives the movable ring 421 to reset via the punch ejection beam 61 and connecting rod 451. The flipping cylinder 35 drives the rotary shaft 3 to rotate 180° again by rotating the second slide 34. The vertical cylinder 31 is activated to control the rotary shaft 3 to move upward. The square slider 32 at the end of the rotary shaft 3 moves upward along the second slide 34. After leaving the second slide 34, it continues to move upward into the first slide 33 to reset, returning to the initial state of the device. Then, the above operation is repeated for continuous production.

[0071] Advantages of this device: This device has a simple structure and produces ice cups using shaved ice as raw material. It can not only form a stable ice cup structure and be used as an ice cream container to keep the ice cream warm, but also crush the ice cream and eat it together to enhance the taste.

[0072] An adjusting screw 541 is coaxially provided on the rear side of the piston rod of the locking cylinder 54. By adjusting the number of turns of the adjusting screw 541 and the nut connector 542, the depth of the wedge-shaped barb 521 inserted into the groove 51 of the locking tongue 5 can be controlled, thereby controlling the extrusion stroke of the ice cup punch 4, that is, controlling the tightness of the ice cup.

[0073] The rotating motor 82 is located on the upper side of the box body 8, corresponding to a material conveying rod 81 located near the middle from left to right. This allows the first and second synchronous belts on both sides to have a more balanced load.

[0074] Synchronous belt drive is a conventional transmission structure. The way synchronous belts, synchronous pulleys, and tension pulleys are matched is well known to those skilled in the art. To simplify the drawings and illustrate the problem simply, all synchronous belts are not shown in this embodiment.
