Description

Technical Field

[0001] This application relates to the field of drying machine technology, and in particular to a limiting structure and a drying system. Background Technology

[0002] In the brewing process of Maotai-flavor liquor, the spreading and cooling process is of great significance for volatilizing impurities in the mash and trapping environmental microorganisms. Mechanized brewing is widely used in the industry. Mechanized spreading typically utilizes a spreading plate chain to transport the mash, and a spreading machine that travels back and forth above the spreading plate chain is used to perform processes such as cooling the mash, sprinkling the tail liquor, and adding yeast and mixing the mash. The spreading machine is set on a track, and the drive device of the spreading machine travels back and forth according to the set start and end coordinates, realizing a series of production processes such as turning and breaking up the mash on the spreading plate chain, cooling and mixing yeast.

[0003] Because the temperature of the mash immediately after steaming is high, the mist emitted from it adheres to the track of the spreading machine. This mist condenses and liquefies, causing the track to become wet. This reduces the friction between the drive unit and the track, leading to frequent slippage. The drive unit may reach the programmed travel distance but turn back before reaching the actual turning point on the track. This premature turning back results in a return distance less than the absolute coordinate value, causing continuous collisions when the spreading machine reaches the end of the track. This situation prevents the spreading machine from achieving complete coverage and turning of the mash on the spreading plate chain, resulting in uneven cooling of some mash and issues such as repeated or missed addition of yeast. Utility Model Content

[0004] The purpose of this application is to solve the aforementioned technical problems by providing a limiting structure and a spreading system, thereby enabling the drive device to move within a preset stroke range and ensuring that the spreading system fully covers the fermented mash within the preset stroke range. To achieve the above objective, the technical solution of this application is as follows:

[0005] In a first aspect, this application provides a limiting structure applied to a driving device. The limiting structure includes a first limiting component and a second limiting component. The first limiting component is mounted on the driving device and moves synchronously with the driving device. The second limiting component is set at a reversing point of a preset stroke of the driving device. The first limiting component and the second limiting component slide in contact. The first limiting component triggers a limiting signal to cause the driving device to change its direction of movement at the reversing point.

[0006] In one possible implementation, the reversing point includes the starting point of the preset travel and / or the ending point of the preset travel.

[0007] In one possible implementation, the second limiting component is located at the start point and the end point respectively; when the driving device moves to the start point, the first limiting component and the second limiting component slide into contact, and the driving device runs from the start point to the end point; when the driving device moves to the end point, the first limiting component and the second limiting component slide into contact, and the driving device runs from the end point to the start point.

[0008] In one possible implementation, the first limiting component includes a first mounting base, an adjusting part, and a rolling part; the first mounting base is connected to the driving device, the adjusting part is rotatably disposed relative to the first mounting base, and the rolling part is disposed on the adjusting part and slides in contact with the second limiting component.

[0009] In one possible implementation, the first limiting component further includes a rotating part, and the adjusting part is rotatably connected to the first mounting base via the rotating part.

[0010] In one possible implementation, the rolling part is located at the end of the adjusting part, and the mounting position of the adjusting part relative to the rotating part is adjustable to change the distance between the rolling part and the rotating part.

[0011] In one possible implementation, a sensor is installed in the first mounting base. The rotation of the rotating part triggers the sensor. The sensor is connected to the controller and transmits a limit signal to the controller. The controller controls the drive device to change the direction of movement.

[0012] In one possible implementation, the second limiting component includes a second mounting base and an abutment portion disposed on the second mounting base; inclined plates are disposed at both ends of the abutment portion, and a rolling portion is slidably disposed along the inclined plates.

[0013] In one possible implementation, the second limiting component further includes a mounting bracket, a second mounting seat connected to the mounting bracket, and the mounting position of the second mounting seat relative to the mounting bracket is adjustable.

[0014] Secondly, this application provides a drying system including the aforementioned limiting structure.

[0015] Compared with the prior art, the advantages of the limiting structure and the drying system in this application are mainly reflected in:

[0016] When the first and second limiting components slide into contact, the drive device changes its direction of movement, ensuring that it only reverses direction when it reaches the reversing point. Multiple reversing points can be set within the preset stroke according to actual usage requirements. These reversing points effectively determine the preset stroke, allowing the drive device to reverse along a specified path under different preset stroke conditions. This makes setting the preset stroke for the drive device more flexible and applicable. The limiting structure, when applied to the spreading system, enables the system to operate comprehensively within the preset stroke range, improving the efficiency of fermentation processing.

[0027] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0028] Example 1

[0029] This embodiment provides a limiting structure applied to a drive device 1. The drive device 1 moves within a preset stroke range, where the preset stroke refers to the absolute value of the moving distance of the drive device 1. The drive device 1 can be used to drive the spreader 52 to reciprocate. The drive device 1 moves along the linear guide rail 2, and the spreader 52 moves along the arrangement direction of the linear guide rail 2 to realize the processing operation of the fermented mash 53. Because existing spreaders 52 may slip when the drive device 1 moves along the linear guide rail 2 during operation, the drive device 1 may turn back before reaching the preset stroke, failing to achieve full coverage processing of the area where the fermented mash 53 is located. This embodiment, by setting a limiting structure in conjunction with the drive device 1, ensures that the drive device 1 moves into position, realizing the full coverage range that the spreader 52 can operate within. The following is a detailed description.

[0030] like Figures 1-4 As shown, a limiting structure includes a first limiting component 3 and a second limiting component 4. The first limiting component 3 is mounted on the driving device 1 and moves synchronously with the driving device 1. The second limiting component 4 is set at a reversing point of a preset stroke of the driving device 1. The first limiting component 3 and the second limiting component 4 slide in contact. The first limiting component 3 triggers a limiting signal to cause the driving device 1 to change its moving direction at the reversing point.

[0031] The drive unit 1 can consist of a motor and a traveling structure, which has wheels and moves along the linear guide rail 2. To ensure that the drive unit 1 can accurately reach the preset stroke, it continuously travels until it reaches the reversing point before changing direction. The reversing method of the traveling mechanism can be achieved by controlling the motor to rotate forward or backward.

[0032] For example, when the first limiting component 3 and the second limiting component 4 slide in contact, the first limiting component 3 is subjected to force and triggers a limiting signal. The limiting signal is fed back to the controller, which controls the drive device 1 to change its direction of movement, thereby ensuring that the drive device 1 only changes direction when it reaches the reversing point. According to actual usage requirements, multiple reversing points can be set in the preset stroke. The reversing points can effectively determine the preset stroke, allowing the drive device 1 to change direction along a specified path under different preset stroke conditions. The way the drive device 1 sets the preset stroke is more flexible and has stronger applicability. It is still applicable to non-linear strokes, such as multi-path intersection strokes or arc strokes. At the same time, the drive device 1 moves within the preset stroke, avoiding collision damage to the end of the linear guide rail 2 due to the drive device 1 moving beyond the preset stroke, reducing the probability of safety hazards.

[0033] In this embodiment, the drive device 1 can drive the spreader 52. The movement range of the drive device 1 is accurate. Accordingly, the drive device 1 drives the spreader 52 to change its movement direction. The movement range of the spreader 52 is accurate. The spreader 52 can achieve full coverage operation within the preset stroke, and can carry out comprehensive processing of the fermented mash 53, ensuring the working efficiency of the spreader 52.

[0034] In one embodiment, the reversing point includes the starting point of the preset travel and / or the ending point of the preset travel.

[0035] To achieve the reciprocating motion of the drive device 1 within a preset stroke, the reversing points can be the start and end points of the preset stroke. Correspondingly, there can be two second limiting components 4. One second limiting component 4 is installed at the starting point of the drive device 1's movement, and the other second limiting component 4 is installed at the ending point of the drive device 1's movement. The second limiting components 4 can be installed on the side of the linear guide rail 2 to achieve accurate matching between the first limiting component 3 and the second limiting component 4.

[0036] For example, when the drive device 1 moves to the starting point of the preset travel distance, the first limiting component 3 and the second limiting component 4 slide into contact, and the drive device 1 moves from the starting point to the ending point; when the drive device 1 moves to the ending point of the preset travel distance, the first limiting component 3 and the second limiting component 4 slide into contact, and the drive device 1 moves from the ending point to the starting point. By limiting the distance between the two second limiting components 4, the preset travel distance of the drive device 1 can be accurately limited.

[0037] In one embodiment, the first limiting component 3 includes a first mounting base 31, an adjusting part 32, and a rolling part 33; the first mounting base 31 is connected to the driving device 1, the adjusting part 32 is rotatably disposed relative to the first mounting base 31, and the rolling part 33 is disposed on the adjusting part 32 and slides in contact with the second limiting component 4.

[0038] The rolling part 33 can be a roller. When the rolling part 33 moves with the drive device 1, it comes into contact with the second limiting component 4. The force applied to the rolling part 33 causes the adjusting part 32 to rotate. The adjusting part 32 rotates relative to the first mounting base 31, triggering a sensor within the first mounting base 31 to generate a limit signal. The sensor transmits the limit signal to the controller, which then controls the drive device 1 to change its direction of movement. The rolling part 33 slides in contact with the second limiting component 4, and the rolling part 33 is rotatably connected to the adjusting part 32. This reduces friction in the rolling part 33, making it easier for the adjusting part 32 to rotate and trigger the limit signal. This results in a highly sensitive method for the drive device 1 to change its direction of movement, allowing for rapid reversal of movement.

[0039] In one embodiment, the first limiting component 3 further includes a rotating part 34, and the adjusting part 32 is connected to the first mounting base 31 through the rotating part 34, and the rotating part 34 is rotatably connected to the first mounting base 31.

[0040] For example, the rolling part 33 is located at the end of the adjusting part 32, and the mounting position of the adjusting part 32 relative to the rotating part 34 is adjustable to change the distance between the rolling part 33 and the rotating part 34. The adjusting part 32 is provided with an adjusting hole 35 arranged along its length direction. The adjusting part 32 is fixed by an adjusting member 36 passing through the adjusting hole 35. The adjusting member 36 can be a bolt. Changing the position of the adjusting member 36 in the adjusting hole 35 adjusts the distance between the rolling part 33 and the rotating part 34, so that the distance between the rolling part 33 and the second limiting component 4 in the vertical direction corresponds to the distance in the vertical direction, where the vertical direction refers to the direction that is approximately perpendicular to the ground.

[0041] The adjusting part 32 is in a vertical position in the normal state, and the rolling part 33 is located at the bottom end of the adjusting part 32. The second limiting component 4 is located below the first limiting component 3. When the first mounting base 31 moves with the driving device 1, the rolling part 33 abuts against the second limiting component 4, and the rolling part 33 drives the adjusting part 32 to tilt and rotate.

[0042] In one embodiment, the second limiting component 4 includes a second mounting base 41 and an abutment portion 42 disposed on the second mounting base 41; the two ends of the abutment portion 42 are provided with inclined plates 43 arranged along the moving direction of the driving device 1, and the rolling portion 33 is slidably disposed along the inclined plates 43.

[0043] The second mounting base 41 has a contact portion 42 at its top, and the second limiting component 4 has a generally T-shaped structure. The contact portion 42 includes a platform 44 and inclined plates 43 disposed at both ends of the platform 44. The inclined plates 43 are offset downward relative to the platform 44, and the rolling portion 33 can slide along the inclined plates 43 to change the rotation angle of the adjusting portion 32. The rolling portion 33 slides smoothly along the inclined plates 43, avoiding any movement jamming.

[0044] In one embodiment, the second limiting component 4 further includes a mounting bracket 45, a second mounting seat 41 connected to the mounting bracket 45, and the mounting position of the second mounting seat 41 relative to the mounting bracket 45 is adjustable.

[0045] The mounting bracket 45 can be roughly U-shaped, with both ends of the mounting bracket 45 mounted on the sides of the linear guide rail 2. The second mounting seat 41 has a mounting opening 46, and the mounting bracket 45 corresponds to the mounting opening 46. The second mounting seat 41 is supported on the mounting bracket 45. The second mounting seat 41 is provided with a fixing member 47 extending into the mounting opening 46. The fixing member 47 moves against the mounting bracket 45. The fixing member 47 can be a bolt. By locking the fixing member 47, the second mounting seat 41 is stably positioned on the mounting bracket 45, so that the tilting plate 43 accurately corresponds to the reversing point, realizing the function of quick adjustment of the second mounting seat 41.

The driving device 1 is moved along the linear guide rail 2 and is used to drive the drying machine 52 to reciprocate. The drying chain plate 51 is located below the linear guide rail 2 and is arranged corresponding to the drying machine 52.

[0049] The fermented mash 53 is laid on the spreading chain plate 51. The drive device 1 drives the spreading machine 52 to move above the spreading chain plate 51. The spreading machine 52 performs turning or other processing on the fermented mash 53. The spreading system has the beneficial effects brought by the limiting structure, which will not be elaborated here.
