Description

Technical Field

[0001] This utility model relates to the technical field of rock sugar production equipment, and in particular to a conveying device for an automatic production line of polycrystalline rock sugar. Background Technology

[0002] The production process of polycrystalline rock sugar includes steps such as pouring into the basin, crystallization, molasses removal, and sugar removal. Specifically, the operator places the crystallization basin on the conveyor belt, then pours high-temperature sugar solution into the crystallization basin on the conveyor belt. The conveyor belt transports the crystallization basin forward, and the operator moves the crystallization basin to the crystallization position and lets it stand for a period of time to allow the crystallization basin to cool and crystallize naturally. The operator then flips the crystallization basin to drain the excess liquid from the crystallization basin. Finally, the polycrystalline rock sugar is separated from the crystallization basin.

[0003] However, the existing polycrystalline rock sugar production process requires manual handling, transfer, and flipping of crystallization basins to complete the above production steps. The process of transferring and flipping crystallization basins is prone to chaos, making crystallization basin management difficult. Furthermore, the crystallization basin conveying efficiency is low. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a conveying device for an automated production line of polycrystalline rock sugar, which can connect and integrate multiple processes of polycrystalline rock sugar production, enabling automated production of polycrystalline rock sugar and improving production efficiency and product quality.

[0005] A conveying device for an automated polycrystalline rock sugar production line according to an embodiment of the present invention includes: a crystallization basin for containing sugar solution; a transmission chain arranged horizontally for cyclically conveying the crystallization basin, the transmission chain having a first conveying direction, a second conveying direction, a third conveying direction, and a fourth conveying direction arranged sequentially; and a tilting frame disposed on the crystallization basin, the tilting frame having an overlapping portion and a hinge portion. In the first conveying direction of the transmission chain, the overlapping portion and the hinge portion are horizontally opposite to each other, the overlapping portion overlapping the top of the transmission chain, and the hinge portion being rotatably disposed on the transmission chain, so that the crystallization basin is in a flat position. In the second conveying direction... In the third and fourth conveying directions, under the weight of the crystallizing basin itself, the overlapping part disengages from the transmission chain; a first abutting member is connected to the overlapping part; a first guide rail is distributed on the outer periphery of the transmission chain and has a first guide section, a second guide section, and a third guide section connected in sequence. The first guide section extends in a curve along the second conveying direction, the second guide section extends in a straight line along the third conveying direction, and the third guide section extends in a curve along the fourth conveying direction. The first abutting member can move in sequence along the first guide section, the second guide section, and the third guide section to guide the crystallizing basin to be in an inclined state at different angles.

When the crystallization basin is in the second conveying direction, the first abutting member moves along the first guide section, and the flipping frame rotates, so that the crystallization basin is in an inclined state. When the crystallization basin is in the third conveying direction, the second abutting member moves along the second guide section, and the opening of the crystallization basin is tilted downwards, so that the honey discharge, honey dripping, and sugar removal steps can be sequentially performed. When the crystallization basin is in the fourth conveying direction, the flipping frame gradually rotates to a horizontal state, so that the crystallization basin can carry out the next polycrystalline production. Thus, the actions of honey discharge and honey dripping in the crystallization basin are consistent, ensuring the quality stability of each batch of polycrystalline rock sugar and improving product quality.

[0009] According to an embodiment of the present invention, a conveying device for an automatic production line of polycrystalline rock sugar includes a tilting frame hinged with an anti-detachment frame, the anti-detachment frame having a second abutment member, a support rail arranged on the outer periphery of the transmission chain, the support rail having a first lifting section and a second lifting section connected to each other, the first lifting section extending in a curve along the second conveying direction, the second lifting section extending in a straight line along the third conveying direction, and the second abutment member being movable sequentially along the first lifting section and the second lifting section, so that the anti-detachment frame approaches the mouth of the crystallization basin.

[0014] According to an embodiment of the present invention, a conveying device for an automatic production line of polycrystalline rock sugar includes a limiting structure provided between the hinge of the flipping frame and the anti-detachment frame.

[0031] The following description, in conjunction with the accompanying drawings, describes a conveying device for an automated polycrystalline rock sugar production line according to an embodiment of the present invention.

[0032] Reference Figure 1 The present invention aims to provide an embodiment of a conveying device for an automated production line of polycrystalline rock sugar.

[0033] A conveying device for an automatic polycrystalline rock sugar production line according to an embodiment of the present invention includes a crystallization basin 100 and a transmission chain 110. The crystallization basin 100 is used to contain sugar solution. The transmission chain 110 is arranged in a horizontal direction and is used to circulate and convey the crystallization basin 100. The transmission chain 110 has a first conveying direction, a second conveying direction, a third conveying direction and a fourth conveying direction arranged in sequence.

[0034] Understandably, by setting up crystallization basins 100 and transmission chains 110, multiple crystallization basins 100 are arranged along the transmission chain 110. The transmission chain 110 circulates and transports the crystallization basins 100 sequentially to the pouring, crystallization, honey discharge, and sugar removal positions. This replaces manual handling, transfer, and turning of the crystallization basins 100, avoiding confusion during the transfer and turning process. As a result, multiple processes of polycrystalline rock sugar production can be connected and integrated, enabling automated production of polycrystalline rock sugar, greatly reducing the management difficulty of the crystallization basins 100, and improving production efficiency.

[0035] This utility model discloses a conveying device for an automated polycrystalline rock sugar production line, referring to... Figure 1 and Figure 2It also includes a tilting frame 120, a first abutment member 150, and a first guide rail 160. The tilting frame 120 is disposed on the crystallizing basin 100. The tilting frame 120 has an overlapping portion 130 and a hinge portion 140. In the first conveying direction of the transmission chain 110, the overlapping portion 130 and the hinge portion 140 are horizontally opposite each other. The overlapping portion 130 overlaps the top of the transmission chain 110, and the hinge portion 140 is rotatably disposed on the transmission chain 110, so that the crystallizing basin 100 is in a flat state. In the second, third, and fourth conveying directions, under the action of the crystallizing basin 100's own gravity, the overlapping portion 130 disengages from the transmission chain 110. 0; The first abutment 150 is connected to the overlapping part 130; The first guide rail 160 is distributed on the outer periphery of the transmission chain 110 and has a first guide section 170, a second guide section 180 and a third guide section 190 connected in sequence. The first guide section 170 extends in a curve along the second conveying direction, the second guide section 180 extends in a straight line along the third conveying direction, and the third guide section 190 extends in a curve along the fourth conveying direction. The first abutment 150 can move in sequence along the first guide section 170, the second guide section 180 and the third guide section 190 to guide the crystallizing basin 100 to be in an inclined state at different angles.

[0036] It should be noted that the first abutment 150 is a roller, which reduces the friction between the first abutment 150 and the first guide rail 160.

[0037] It is understandable that by setting up the flipping frame 120, the first abutment 150, and the first guide rail 160, when the crystallizing basin 100 is in the first conveying direction, the flipping frame 120 is in a horizontal state, so that the crystallizing basin 100 is also in a horizontal state, and the crystallizing basin 100 can sequentially perform the filling and crystallization steps. When the crystallizing basin 100 is in the second conveying direction, the first abutment 150 moves along the first guide section 170, and the flipping frame 120 rotates, so that the crystallizing basin 100 is in an inclined state. When the crystallizing basin 100 is in the third conveying direction, the second abutment 210 moves along the second guide section 180, and the opening of the crystallizing basin 100 is tilted downwards, so that the honey discharge, honey dripping, and sugar removal steps can be performed sequentially. When the crystallizing basin 100 is in the fourth conveying direction, the flipping frame 120 gradually rotates to a horizontal state, so that the crystallizing basin 100 can perform the next polycrystalline production. Thus, the actions of honey discharge and honey dripping of the crystallizing basin 100 are consistent, ensuring the quality stability of each batch of polycrystalline rock sugar and improving product quality.

[0038] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2 , Figure 3 and Figure 5The tilting frame 120 is hinged with an anti-detachment frame 200, which is provided with a second abutment member 210. The outer periphery of the transmission chain 110 is provided with a support rail 220, which has a first lifting section 230 and a second lifting section 240 connected to each other. The first lifting section 230 extends in a curve along the second conveying direction, and the second lifting section 240 extends in a straight line along the third conveying direction. The second abutment member 210 can move sequentially along the first lifting section 230 and the second lifting section 240, so that the anti-detachment frame 200 is close to the mouth of the crystallization basin 100.

[0039] It should be noted that the second abutment 210 is a roller, which reduces the friction between the second abutment 210 and the support rail 220.

[0040] By setting up an anti-detachment frame 200, a support rail 220, and a second abutment member 210, when the crystallization basin 100 is in the second conveying direction, the second abutment member 210 moves along the first lifting section 230, so that the anti-detachment frame 200 gradually approaches the mouth of the crystallization basin 100. When the crystallization basin 100 is in the third conveying direction, the second abutment member 210 moves along the second lifting section 240. The anti-detachment frame 200 can prevent the polycrystalline rock sugar in the crystallization basin 100 from detaching, thereby separating the polycrystalline rock sugar from the excess sugar solution, which facilitates the subsequent sugar removal process.

[0041] Furthermore, a first collection mechanism 320 is provided below the second lifting section 240. The first collection mechanism 320 can be a collection box, which collects excess sugar liquid.

[0042] In some embodiments of this utility model, a second guide rail 250 is arranged on the outer periphery of the transmission chain 110. The second guide rail 250 has a fourth guide section 260 and a fifth guide section 270 that are connected to each other. The fourth guide section 260 extends in a straight line along the first conveying direction, and the fifth guide section 270 extends in a curve along the second conveying direction. The second abutment member 210 can move sequentially above the fourth guide section 260 and the fifth guide section 270.

[0043] It is understandable that when the crystallization basin 100 moves from the first conveying direction to the second conveying direction, the tilting frame 120 rotates, causing the anti-detachment frame 200 to rotate to the direction of the opening of the crystallization basin 100. Due to the action of gravity, if the anti-detachment frame 200 directly collides with the crystallization basin 100, the polycrystalline rock sugar in the crystallization basin 100 may fall off, making it impossible to separate the polycrystalline rock sugar from the excess sugar solution. Therefore, by using the second abutment member 210 to move sequentially above the fourth guide section 260 and the fifth guide section 270, it is beneficial to make the anti-detachment frame 200 gradually approach the opening of the crystallization basin 100, thus avoiding the situation where the anti-detachment frame 200 collides with the crystallization basin 100.

[0044] In some embodiments of this utility model, a guide channel 280 is formed between the curved outer side of the fifth guide segment 270 and the curved inner side of the first lifting segment 230, and the guide channel 280 accommodates the passage of the second abutment member 210.

[0045] Understandably, the second abutment 210 can pass through the guide channel 280, which serves as a connector between the fifth guide section 270 and the first lifting section 230, ensuring that the anti-detachment frame 200 can smoothly approach the mouth of the crystallizing basin 100.

[0046] In some embodiments of this utility model, reference is made to Figure 4 and Figure 6 A limiting structure 300 is provided between the hinge of the flipping frame 120 and the anti-detachment frame 200. The limiting structure 300 is used to prevent the anti-detachment frame 200 from rotating in the direction away from the mouth of the crystallization basin 100.

[0047] Specifically, the anti-detachment frame 200 has a sleeve, and the flipping frame 120 has a support shaft. The sleeve is fitted onto the support shaft, thereby allowing the flipping frame 120 and the anti-detachment frame 200 to rotate relative to each other.

[0048] To prevent the anti-detachment frame 200 from flipping to the outside of the crystallization basin 100, a limiting structure 300 can be set between the support shaft and the sleeve. The sleeve is provided with a relief groove, and the support shaft is provided with a limiting pin. The limiting pin is in the relief groove, thereby preventing the anti-detachment frame 200 from rotating in the direction away from the opening of the crystallization basin 100, while ensuring that the anti-detachment frame 200 can rotate to approach the opening of the crystallization basin 100.

[0049] In some embodiments of this utility model, the top of the second guide section 180 is provided with a plurality of protrusions, which are arranged along the length direction of the second guide section 180 and are located away from the support rail 220.

[0050] Therefore, when the first contact 150 passes through several sequentially arranged protrusions, the crystallization basin 100 will bounce up and down, which is conducive to the detachment of polycrystalline rock sugar in the crystallization basin 100, thereby realizing automatic sugar removal.

[0051] Furthermore, a second collection mechanism 330 is provided below several protrusions. The second collection mechanism 330 can be a conveyor belt, which transports the detached polycrystalline rock sugar to the next process.

[0052] In some embodiments of this utility model, the protrusion is a right-angled triangular upright plate 290, the top of the upright plate 290 has an inclined surface, and the first abutment member 150 can move along the inclined surface.

[0053] Understandably, the first abutment 150 moves upward along the inclined plane, making it easier for the crystallizing basin 100 to move to a higher position. When the first abutment 150 falls back to the second guide section 180, it will generate a large impact, ensuring that the polycrystalline rock sugar falls off and preventing the first abutment 150 from getting stuck when passing the protrusion.

[0054] Meanwhile, the right-angled triangular upright plate 290 has a simple structure and is easy to manufacture.

[0055] In some embodiments of this utility model, reference is made to Figure 1 The distance between the second guide section and the transmission chain 110 is The distance between the first guide segment and the transmission chain 110 is , .

[0056] Therefore, when the first abutting member 150 passes through the first guide section, it can guide the crystallization basin 100 to gradually tilt, avoiding the situation where the opening of the crystallization basin 100 immediately flips over and inverts, causing the polycrystalline rock sugar to detach from the crystallization basin 100, thus ensuring the smooth progress of the sugar removal step; when the first abutting member 150 passes through the second guide section, it can make the crystallization basin 100 tilt at a certain angle, and the opening of the crystallization basin 100 faces downward, which is convenient for the sugar removal step.

[0057] In some embodiments of this utility model, two transmission chains 110 are provided, the two transmission chains 110 are arranged opposite to each other, and the crystallization basin 100 is arranged between the two transmission chains 110.

[0058] Therefore, using two transmission chains 110 to transport the crystallization basin 100 is beneficial for the smooth movement of the crystallization basin 100 in the first, second, third, and fourth transmission directions, while ensuring that the transmission chains 110 effectively support the crystallization basin 100.

[0059] In some embodiments of this utility model, reference is made to Figure 4 The flipping frame 120 has a square connecting frame 310, which is connected to the mouth of the crystallization basin 100.

[0060] Therefore, by connecting the connecting frame 310 to the mouth of the crystallizing basin 100, the structure of the conveying device can be made more compact, and the vertical space occupied by the conveying device can be reduced.

[0061] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0062] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
