Description

Technical Field

[0001] The utility model relates to the technical field of candied haws machines, in particular to a sugar melting device with a positioning mechanism. Background Art

[0002] Sugar-coated haws are a traditional Chinese delicacy. The raw materials are hawthorn berries and syrup. The main method is to string hawthorn berries on bamboo sticks, then pour syrup on the hawthorn berries, and wait for the syrup to solidify before enjoying. The existing method of processing sugar-coated haws is to string hawthorn berries into strings and place them on a processing table, pour syrup on them, turn the hawthorn berries strings from time to time to ensure that the hawthorn berries are evenly coated with syrup, and then let them stand for a while. After the syrup solidifies, the sugar-coated haws are ready. Then, the processed sugar-coated haws are taken off, and new hawthorn berries are placed on them. Repeat the above operation to make the next batch of sugar-coated haws.

[0003] The inventor invented and designed a new candied haws preparation device for the existing candied haws production. The device mainly comprises a sugar melter, which comprises a sugar melting tank and a transmission rod fixedly connected to the bottom of the sugar melting tank. When making candied haws, sugar is placed in the sugar melter in advance. After the sugar is heated and melted into syrup, strings of hawthorn fruits are placed in the sugar melting tank, and the hawthorn fruit strings are rotated for several weeks so that the surface of the hawthorn fruits is evenly coated with a layer of syrup to form preliminary candied haws. The hawthorn fruits are then taken out of the sugar melting tank, placed aside to stand and dry, and the candied haws are ready after the syrup solidifies. After the candied haws are coated with syrup in the sugar melting tank and taken out, the inner wall of the sugar melting tank is still stained with syrup. By connecting and fixing the transmission rod to the bottom of the sugar melting tank, the transmission rod drives the sugar melting tank to rotate at a high speed, so that the remaining syrup in the sugar melting tank is thrown out under the action of centrifugal force during the high-speed rotation to maintain the hygiene in the sugar melting tank.

[0004] However, after the sugar melting tank has completed the work of throwing sugar, it has experienced high-speed rotation. In order to facilitate the subsequent repeated placement of hawthorn strings, the position of the sugar melting tank needs to be restored to its original position after rotation. Therefore, how to restore the position of the sugar melting tank to its original position after rotation needs to be improved. Utility Model Content

[0018] In the utility model, the transmission rod is connected and fixed to the bottom of the sugar melting tank, so when the transmission rod drives the sugar melting tank to rotate at a high speed, the two rotate synchronously. Therefore, a positioning detection mechanism is set on one side of the bracket, and a detection site is set on the sugar melting tank or the transmission rod, so that when the positioning detection mechanism identifies the detection site, it means that the transmission rod has driven the sugar melting tank to rotate to the original position. At this time, the positioning detection mechanism transmits the information to the controller in real time, and the controller simultaneously controls the driving mechanism to stop driving the transmission rod to rotate, so that the sugar melting tank stops rotating, and the sugar melting tank can be guaranteed to return to the original position; or, when the positioning detection mechanism identifies the detection site, the positioning detection mechanism transmits the information to the controller in real time, and the controller simultaneously controls the driving mechanism to drive the transmission rod to continue to rotate a certain angle, so that the transmission rod continues to drive the sugar melting tank to rotate a certain number of preset angles, until the sugar melting tank stops when it rotates to the original position, and the sugar melting tank can be guaranteed to return to the original position. In this structure, the detection site can be set on the sugar melting tank or the transmission rod, and the use of the positioning detection mechanism can ensure that the sugar melting tank is reset after the sugar throwing work is completed, which is convenient for the subsequent repeated placement of the hawthorn string.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] See also Figures 1 to 18 The utility model discloses a sugar melting device with a positioning mechanism, including a sugar melter 1, a bracket 2, a heating mechanism 3, and a driving mechanism 4. The sugar melter 1 includes a sugar melting groove 11 and a transmission rod 12. The heating mechanism 3 is arranged below the sugar melting groove 11. A through hole 31 is arranged in the middle of the heating mechanism 3. The transmission rod 12 passes through the through hole 31 and connects and fixes the driving mechanism 4 and the bottom of the sugar melting groove 11. The driving mechanism 4 is used to drive the transmission rod 12 to rotate. The heating mechanism 3 and the driving mechanism 4 are both fixed on the bracket 2; a positioning detection mechanism 5 is arranged on one side of the bracket 2, and a detection site 6 is arranged on the sugar melting groove 11 or the transmission rod 12; the driving mechanism 4 and the positioning detection mechanism 5 are both electrically connected to the controller.

[0041] Sugar-coated haws are mainly made by passing a bamboo stick through a plurality of hawthorn fruits and then pouring syrup on the outer layer. In the utility model, sugar is placed in advance in the sugar melter 1, and after the sugar is heated and melted into syrup, the hawthorn fruits in a string are placed in the sugar melting tank 11, and the hawthorn fruit string is rotated for a few weeks so that the surface is evenly coated with a layer of syrup to form a preliminary sugar-coated haws, which is then taken out of the sugar melting tank 11, placed aside to stand and dry, and after the syrup solidifies, the sugar-coated haws are ready; after the sugar-coated haws are coated with syrup in the sugar melting tank 11 and taken out, the inner wall of the sugar melting tank 11 is still stained with syrup, and the transmission rod 12 is connected and fixed to the bottom of the sugar melting tank 11, and the transmission rod 12 drives the sugar melting tank 11 to rotate at a high speed, so that the remaining syrup in the sugar melting tank 11 is thrown out under the action of centrifugal force during the high-speed rotation, so as to maintain the hygiene in the sugar melting tank 11.

[0042] Specifically, the bracket 2 is used to fix the positions of the driving mechanism 4 and the heating mechanism 3. The heating mechanism 3 is arranged below the molten sugar tank 11 to heat the molten sugar tank 11 and melt the sugar in the molten sugar tank 11 into syrup. A through hole 31 is arranged in the middle of the heating mechanism 3. The transmission rod 12 passes through the through hole 31 and connects the driving mechanism 4 and the molten sugar tank 11. When the sugar-coated haws are taken out of the molten sugar tank 11 and the molten sugar tank 11 needs to be rotated to throw out the syrup, the transmission rod 12 drives the molten sugar tank 11 to rotate at a high speed under the drive of the driving mechanism 4 to throw out the syrup residue. By throwing away the remaining syrup of this operation, the syrup can be quickly processed and cleaned after each operation to prevent the syrup from being heated and carbonized or repeatedly cooled and heated, and prepare for the next rapid heating.

[0043] After the sugar melting tank 11 completes the sugar throwing work, since it has experienced high-speed rotation, the position of the sugar melting tank 11 needs to be restored to its original position after rotation, so as to facilitate the subsequent repeated work of placing the hawthorn strings. Since the transmission rod 12 is connected and fixed to the bottom of the molten sugar tank 11, when the transmission rod 12 drives the molten sugar tank 11 to rotate at a high speed, the two rotate synchronously. Therefore, a positioning detection mechanism 5 is set on one side of the bracket 2, and a detection site 6 is set on the molten sugar tank 11 or the transmission rod 12, so that when the positioning detection mechanism 5 identifies the detection site 6, it means that the transmission rod 12 has driven the molten sugar tank 11 to rotate to the original position. At this time, the positioning detection mechanism 5 transmits the information to the controller in real time, and the controller simultaneously controls the driving mechanism 4 to stop driving the transmission rod 12 to rotate, so that the molten sugar tank 11 stops rotating, which can ensure that the molten sugar tank 11 returns to its original position; or, when the positioning detection mechanism 5 identifies the detection site 6, the positioning detection mechanism 5 transmits the information to the controller in real time, and the controller simultaneously controls the driving mechanism 4 to drive the transmission rod 12 to continue to rotate by a certain angle, so that the transmission rod 12 continues to drive the molten sugar tank 11 to rotate by a certain preset angle until the molten sugar tank 11 stops when it rotates to the original position, which can ensure that the molten sugar tank 11 returns to its original position. In this structure, the detection site 6 can be set on the sugar melting tank 11 or the transmission rod 12. When used in conjunction with the positioning detection mechanism 5, it can ensure that the sugar melting tank 11 is reset after completing the sugar throwing work, which is convenient for the subsequent repeated placement of the hawthorn strings.

[0044] Furthermore, the detection site 6 is fixed below the molten sugar tank 11 near the edge. Since the radius of the molten sugar tank 11 is greater than the radius of the transmission rod 12, when the detection site 6 is fixed below the molten sugar tank 11 near the edge, the rotation stroke of the detection site 6 is also the largest under the same conditions, thereby improving the accuracy of the detection of the positioning detection mechanism 5.

[0045] Furthermore, a bottom plate is provided below the molten sugar tank 11, and the bottom plate is preferably a circular bottom plate, and the detection site 6 is fixed near the edge of the bottom plate. As above, this structure can improve the accuracy of the detection of the positioning detection mechanism 5.

[0046] Furthermore, the positioning detection mechanism 5 is a photocell, and a baffle cooperating with the photocell is provided on the detection site 6. When the photocell detects the baffle, the positioning recognition is completed. Preferably, the positioning detection mechanism 5 can also be an induction switch, and when it detects the detection site 6, the next step can be performed.

[0047] Furthermore, the positioning detection mechanism 5 is a proximity switch, which has high recognition accuracy and fast recognition speed. When it detects the detection position 6, it can proceed to the next step.

[0048] Furthermore, it also includes a connecting plate 7, through which the positioning detection mechanism 5 is fixed to the bracket 2, and the connecting plate 7 is used to fix the position of the positioning detection mechanism 5 on the bracket 2 to prevent it from being displaced.

The transmission rod 12 passes through the first hole, the heating fixing plate 23 and the through hole 31 in sequence and is plugged into the bottom of the sugar melting tank 11. The first support column 22 is provided between the heating fixing plate 23 and the first support plate 21, and is used to fix the position of the heating fixing plate 23 on the first support plate 21.
