A first embodiment of the present invention provides a transfer apparatus, referring to fig. 1 and 2, including:
at least two first gears 1, wherein the at least two first gears 1 are arranged at intervals from left to right;
the second gears 2 are arranged between each group of two adjacent first gears 1, and each second gear 2 is meshed with two adjacent first gears 1 respectively;
the driving device 3 is connected with any one of the second gears 2, and the driving device 3 is used for driving the corresponding second gear 2 to rotate clockwise or anticlockwise; wherein, the driving device 3 can comprise a motor and a matched transmission device, the transmission device can be a driving gear connected to a motor shaft, and the driving gear is meshed with the second gear 2, so that the second gear 2 can be driven to rotate by the motor;
a first conveying rack 4 provided with a first loading level (not shown in the figures), the first conveying rack 4 being in engagement with at least one first gear wheel 1;
when the second gear 2 rotates clockwise, the first conveying rack 4 is used for moving rightwards under the drive of the first gear 1, so that the empty first loading level enters the first loading station 7 on the right side to perform loading operation until the first conveying rack 4 is meshed with the first gear 1 on the rightmost end;
When the second gear 2 rotates anticlockwise, the first conveying rack 4 is used for moving leftwards under the driving of the first gear 1, so that the fully loaded first loading position enters the left first unloading station 8 to execute unloading operation until the first conveying rack 4 is meshed with the leftmost first gear 1 only.
In this embodiment, the first gears 1 and the second gears 2 are disposed in the hollow space, and illustratively, when the driving device 3 drives any one of the second gears 2 to rotate clockwise, the second gears 2 will drive two adjacent first gears 1 to rotate counterclockwise, and the two first gears 1 will drive the other two second gears 2 meshed therewith to rotate clockwise, and so on, i.e. when any one of the second gears 2 rotates clockwise, all the second gears 2 will be driven to rotate clockwise synchronously and all the first gears 1 are driven to rotate counterclockwise synchronously. Similarly, when the driving device 3 drives any one of the second gears 2 to rotate anticlockwise, the second gears 2 will drive the adjacent two first gears 1 to rotate clockwise, and the two first gears 1 will drive the other two second gears 2 meshed with the second gears to rotate anticlockwise, and so on, i.e. when any one of the second gears 2 rotates anticlockwise, all the second gears 2 will be driven to rotate anticlockwise synchronously, and all the first gears 1 will be driven to rotate clockwise synchronously.
The first conveying rack 4 can be arranged at the lower side of the first gear 1, and when the first gear 1 rotates anticlockwise, the first conveying rack 4 is driven to move rightwards; when the first gear 1 rotates clockwise, the first conveying rack 4 is driven to move leftwards. The first loading level is a position on the first conveying rack 4 for loading a workpiece to be conveyed, and the first loading level may be disposed in the middle of the first conveying rack 4, so as to reserve a portion for engaging with the rightmost first gear 1 for the left end of the first conveying rack 4, and reserve a portion for engaging with the leftmost first gear 1 for the right end of the first conveying rack 4. It will be appreciated that a plurality of workpieces may be placed in sequence in a left-to-right direction on the first load level.
Based on the above configuration, taking the number of the first gears 1 as four as shown in fig. 2 and the number of the second gears 2 as three as shown in fig. 2 as an example, the specific workflow and the corresponding technical effects of the transfer apparatus provided in this embodiment are described as follows:
as shown in fig. 2, in the initial state, the first conveying racks 4 are simultaneously meshed with the four first gears 1, and no workpiece is placed on the first loading position, i.e. the first loading position is in an empty state; firstly, driving the corresponding second gear 2 to rotate clockwise through the driving device 3 so as to drive the first conveying rack 4 to move rightwards through the first gear 1, so that the empty first loading level gradually enters the first loading station 7 on the right side along with the movement of the first conveying rack 4; since the first conveying rack 4 has a limited length, in the process of moving the first conveying rack 4 rightward, the leftmost first gear 1 will be separated from the first conveying rack 4 first, and then the second first gear 1 is separated from the first conveying rack 4 from the left until the first conveying rack 4 moves rightward to engage with only the rightmost first gear 1; when the first conveying rack 4 is only meshed with the first gear 1 at the rightmost end, the first loading position completely enters the first loading station 7, and the corresponding second gear 2 is driven by the driving device 3 to rotate anticlockwise at the moment, so that the first conveying rack 4 is driven to move leftwards through the first gear 1, the first loading position gradually leaves the first loading station 7 along with the movement of the first conveying rack 4, and meanwhile, an operator or automatic loading equipment continuously places a workpiece on the first loading position at the first loading station 7; as the number of workpieces on the first loading level increases, the greater the driving force required for driving the first conveying rack 4, that is, the greater the gear teeth of the first gear 1 receive a force (hereinafter, simply referred to as a force) applied by the first conveying rack 4, when the force exceeds a critical load-bearing capacity of the first gear 1, there will be a risk of slipping the gear teeth; however, while the first loading level is continuously fed, the first conveying rack 4 is also continuously moved leftwards to be sequentially re-meshed with the third first gear 1 from the left, the second first gear 1 from the left and the first gear 1 at the leftmost end; in this process, along with the increase of the number of the first gears 1 meshed with the first conveying racks 4, the acting force exerted by the first conveying racks 4 is gradually dispersed to more first gears 1, so that the acting force gradually increased by the continuous feeding of the first conveying racks 4 can be counteracted, the acting force born by the gear teeth of each first gear 1 is ensured not to exceed the critical bearing capacity of the gear teeth, and the problem of tooth slipping is avoided. In short, when the first conveying rack 4 is meshed with only the first gear 1 at the rightmost end, as the feeding operation proceeds, when the acting force reaches the critical bearing capacity of the first gear 1 at the rightmost end, the first conveying rack 4 is meshed with the third first gear 1 from the left again, and at this time, the acting force is dispersed to the two first gears 1, and the acting force borne by each first gear 1 does not exceed the critical bearing capacity thereof; with the continuous feeding operation, when the acting force reaches the critical bearing capacity of the two first gears 1, the first conveying rack 4 is re-meshed with the second first gear 1 from the left, at this time, the acting force is dispersed to the three first gears 1, and the acting force born by each first gear 1 does not exceed the critical bearing capacity of the first gears, and so on.
When the first loading level completely leaves the first loading station 7, the first loading level is in a full-load state of fully filling the workpiece, and gradually enters the first unloading station 8 on the left side along with the first conveying rack 4 continuously moving leftwards; in the process that the first loading position enters the first blanking station 8, an operator or automatic feeding equipment continuously unloads the workpiece on the first loading position at the first blanking station 8, so that the conveying process of the workpiece from the first loading station 7 to the first blanking station 8 is completed; as the number of workpieces on the first load level decreases, the smaller the driving force required to drive the first conveying rack 4, i.e., the smaller the gear teeth of the first gear 1 are subjected to the force exerted by the first conveying rack 4; in response to this change, since the length of the first conveying rack 4 is limited, in the process of moving the first conveying rack 4 leftwards, the first gear 1 at the rightmost end will be separated from the first conveying rack 4 first, and then the third first gear 1 from the left is separated from the first conveying rack 4 until the first conveying rack 4 moves leftwards to be engaged with the first gear 1 at the leftmost end only, in this process, the number of first gears 1 engaged with the first conveying rack 4 is reduced at a speed adapted to the blanking speed of the first loading level, so as to ensure that the number of first gears 1 currently engaged with the first conveying rack 4 is adapted to the magnitude of the acting force exerted by the first conveying rack 4. It will be appreciated that, as the number of meshing groups increases, the requirements for the precision, the synchronicity, etc. of the engagement of the first gear 1 and the first conveying rack 4 are higher, and the probability of occurrence of a meshing problem between each first gear 1 and the first conveying rack 4 due to a small deviation in precision, synchronicity, etc. also increases, thereby possibly causing the normal operation of the first gear 1 and the first conveying rack 4 to be blocked, and possibly causing adverse effects on the conveying process. Based on the above operation, the number of the first gears 1 meshed on the first conveying rack 4 can be timely reduced under the condition that the load of the first conveying rack 4 is reduced and the acting force applied by the first conveying rack 4 is not required to be dispersed through the excessive first gears 1, so that the risk of meshing problems caused by excessive meshing groups is reduced on the premise that the acting force does not exceed the critical bearing capacity of each first gear 1, and the first gears 1 and the first conveying rack 4 can normally operate, and the conveying process can be smoothly carried out.
When the first conveying rack 4 moves leftwards until the first loading position completely enters the first blanking station 8, all workpieces on the first loading position are completely unloaded, and the first conveying rack 4 is only meshed with the first gear 1 at the leftmost end; at this time, the driving device 3 drives the corresponding second gear 2 to rotate clockwise, so that the first gear 1 drives the first conveying rack 4 to move rightwards, so that the empty first loading position gradually enters the first loading station 7 on the right side along with the movement of the first conveying rack 4, and the operations are repeated repeatedly in a circulating manner, so that the workpiece of the first loading station 7 is continuously conveyed to the first unloading station 8.
Therefore, the transfer device provided by the embodiment can stably convey the workpiece of the first feeding station 7 to the first discharging station 8 through the meshing transmission among the first gear 1, the second gear 2 and the first conveying rack 4; in the feeding stage, when the number of workpieces at the first loading position is continuously increased so that the acting force exerted by the first conveying racks 4 on the first gears 1 is continuously increased, the number of the first gears 1 meshed on the first conveying racks 4 is also continuously increased along with the movement of the first conveying racks 4, so that the acting force exerted by the first conveying racks 4 on the first gears 1 can be gradually dispersed to more first gears 1, the acting force born by each first gear 1 is ensured not to exceed the critical bearing capacity, the occurrence of the problem of tooth slipping is avoided, and the risk of damage to devices is reduced; in the blanking stage, when the number of workpieces at the first loading position is continuously reduced so that the acting force exerted by the first conveying racks 4 on the first gears 1 is continuously reduced, the number of the first gears 1 meshed on the first conveying racks 4 is also timely reduced along with the movement of the first conveying racks 4, so that the risk of meshing problems caused by excessive meshing groups can be reduced on the premise of ensuring that the acting force exerted by the first conveying racks 4 does not exceed the critical bearing capacity of each first gear 1, and the first gears 1 and the first conveying racks 4 can normally operate, and the conveying process can be smoothly carried out. Based on the conveying process, the number of the meshing groups between the first gear 1 and the first conveying rack 4 can be independently and reasonably distributed in the whole conveying process while normal conveying of the workpiece is completed, so that conveying quality is improved, and the reliability of equipment operation is improved.
Further, referring to fig. 1 and 3, in a second exemplary embodiment, the transfer apparatus includes a second conveying rack 5, the second conveying rack 5 being provided with a second loading level (not illustrated in the drawings), the second conveying rack 5 being engaged with at least one second gear 2;
when the second gear 2 rotates clockwise, the second conveying rack 5 is used for moving rightwards under the driving of the second gear 2, so that the full-load second loading level enters the second unloading station 10 on the right side to execute unloading operation until the second conveying rack 5 is only meshed with the second gear 2 on the rightmost end;
when the second gear 2 rotates anticlockwise, the second conveying rack 5 is used for moving leftwards under the drive of the second gear 2, so that the empty second loading position enters the left second loading station 9 for loading operation until the second conveying rack 5 is only meshed with the leftmost second gear 2.
In this embodiment, the second conveying rack 5 may be disposed on the upper side of the second gear 2, and when the second gear 2 rotates clockwise, the second conveying rack 5 is driven to move rightward; when the second gear wheel 2 rotates anticlockwise, the second conveying rack 5 is driven to move leftwards. The second loading level is a position on the second conveying rack 5 for loading a workpiece to be conveyed, and the second loading level may be disposed in the middle of the second conveying rack 5, so as to reserve a portion for engaging with the rightmost second gear 2 for the left end of the second conveying rack 5, and reserve a portion for engaging with the leftmost second gear 2 for the right end of the second conveying rack 5. It will be appreciated that a plurality of workpieces may be placed in sequence in a left-right direction on the second load level.
In the actual production process, in the process of conveying one batch of workpieces from the station A to the station B, there may be a case where another batch of workpieces needs to be conveyed from the station B to the station A, for example, a shell needs to be connected with one standard component at the station A, then the connected shell is conveyed to the station B for processing, and then the processed shell is conveyed back to the station A for continuous connection with another standard component. For the application scenario, the second conveying rack 5 is correspondingly added in the embodiment so as to meet the requirement of conveying another batch of workpieces back. It should be noted that, in this embodiment, the first feeding station 7 and the second discharging station 10 are both located on the right side as shown in fig. 3, and collectively correspond to the station a in the above description; the first blanking station 8 and the second loading station 9 in this embodiment are both located on the left side as shown in fig. 3, and collectively correspond to the B station in the above description.
Specifically, taking the number of the first gears 1 as four shown in fig. 3 and the number of the second gears 2 as three shown in fig. 3 as an example, taking the workpiece conveyed by the first conveying rack 4 as a first target workpiece and the workpiece conveyed by the second conveying rack 5 as a second target workpiece, the specific workflow and the corresponding technical effects of the transfer device provided in the embodiment are as follows:
As shown in fig. 3, in the initial state, the first conveying racks 4 are simultaneously meshed with the four first gears 1, and no workpiece is placed on the first loading position, i.e. the first loading position is in an empty state; the second conveying racks 5 are simultaneously meshed with the three second gears 2, and the second loading position is filled with the second target workpiece, namely, the second loading position is in a full loading state. Firstly, the corresponding second gear 2 is driven to rotate clockwise through the driving device 3, so that the first conveying rack 4 is driven to move rightwards through the first gear 1, the empty first loading material level gradually enters the first loading station 7 on the right side along with the movement of the first conveying rack 4, meanwhile, the second conveying rack 5 is driven to move rightwards through the second gear 2, and the full second loading material level gradually enters the second unloading station 10 on the right side along with the movement of the second conveying rack 5.
In the process of moving the first conveying rack 4 rightwards, the leftmost first gear 1 is firstly separated from the first conveying rack 4, and then the second first gear 1 is separated from the first conveying rack 4 from the left until the first conveying rack 4 moves rightwards to be meshed with the rightmost first gear 1; when the first conveyor rack 4 is only engaged with the first right-most gearwheel 1, the first loading level has completely entered the first loading station 7.
In the process that the second loading position enters the second blanking station 10, an operator or automatic feeding equipment continuously unloads a second target workpiece on the second loading position at the second blanking station 10, so that the conveying process of the second target workpiece from the second loading station 9 to the second blanking station 10 is completed; as the number of second target workpieces on the second load level decreases, the smaller the driving force required to drive the second conveying rack 5, i.e., the smaller the applied force that the gear teeth of the second gear 2 apply by the second conveying rack 5; in response to this change, since the length of the second conveying rack 5 is limited, in the process of moving the second conveying rack 5 rightward, the leftmost second gear 2 will be separated from the second conveying rack 5 first, and then the leftmost second gear 2 is separated from the second conveying rack 5 until the second conveying rack 5 moves rightward to engage with only the rightmost second gear 2, in this process, the number of second gears 2 engaged with the second conveying rack 5 is reduced at a speed adapted to the blanking speed of the second loading level, so as to ensure that the number of second gears 2 currently engaged with the second conveying rack 5 is adapted to the amount of force applied by the second conveying rack 5. It will be understood that, as the number of meshing groups increases, the requirements for the precision, the synchronicity, etc. of the second gear 2 and the second conveying rack 5 are higher, and the probability of occurrence of a meshing problem between each second gear 2 and the second conveying rack 5 due to a small deviation in precision, synchronicity, etc. also increases, so that the normal operation of the second gear 2 and the second conveying rack 5 may be blocked, and thus the conveying process may be adversely affected. Based on the above operation, the number of the second gears 2 meshed on the second conveying rack 5 can be timely reduced under the condition that the load of the second conveying rack 5 is reduced and the acting force applied by the second conveying rack 5 is not required to be dispersed through the excessive second gears 2, so that the risk of meshing problems caused by excessive meshing groups is reduced on the premise that the acting force does not exceed the critical bearing capacity of each second gear 2, and the second gears 2 and the second conveying rack 5 can normally operate, and the conveying process can be smoothly carried out.
When the second conveying rack 5 moves rightward until the second loading position completely enters the second unloading station 10, all the second target workpieces on the second loading position are unloaded, the second conveying rack 5 is only meshed with the rightmost second gear 2, and the first conveying rack 4 is only meshed with the rightmost first gear 1. At this time, the corresponding second gear 2 is driven to rotate anticlockwise by the driving device 3, so that the second conveying rack 5 is driven to move leftwards by the second gear 2, meanwhile, the first conveying rack 4 is driven to move leftwards by the first gear 1, so that the first loading position gradually leaves the first loading station 7 along with the movement of the first conveying rack 4, and meanwhile, an operator or automatic loading equipment continuously places the first target workpiece on the first loading position at the first loading station 7; as the number of first target workpieces on the first load level increases, the greater the driving force required to drive the first conveying rack 4, i.e., the greater the force exerted by the first conveying rack 4 on the teeth of the first gear 1. While the first loading level is continuously fed, the first conveying rack 4 is also continuously moved leftwards to be sequentially re-meshed with the third first gear 1 from the left, the second first gear 1 from the left and the first gear 1 at the leftmost end; in this process, along with the increase of the number of the first gears 1 meshed with the first conveying racks 4, the acting force exerted by the first conveying racks 4 is gradually dispersed to more first gears 1, so that the acting force gradually increased by the continuous feeding of the first conveying racks 4 can be counteracted, the acting force born by the gear teeth of each first gear 1 is ensured not to exceed the critical bearing capacity of the gear teeth, and the problem of tooth slipping is avoided.
When the first loading level completely leaves the first loading station 7, the first loading level is in a full loading state of fully filling the first target workpiece, and as the first conveying rack 4 and the second conveying rack 5 continuously move leftwards, the first loading level gradually enters the first unloading station 8 on the left side, and the second loading level gradually enters the second loading station 9 on the left side. In the process that the first loading position enters the first blanking station 8, an operator or automatic feeding equipment continuously unloads the first target workpiece on the first loading position at the first blanking station 8, so that the conveying process of the first target workpiece from the first feeding station 7 to the first blanking station 8 is completed. As the number of first target workpieces on the first load level decreases, the smaller the driving force required to drive the first conveying rack 4, i.e., the smaller the applied force that the gear teeth of the first gear 1 apply by the first conveying rack 4; in response to this change, during the leftward movement of the first conveying rack 4, the first gear 1 at the rightmost end will be separated from the first conveying rack 4 first, and then the third first gear 1 from the left is separated from the first conveying rack 4 until the first conveying rack 4 moves leftward to engage with only the first gear 1 at the leftmost end, during which the number of first gears 1 engaged with the first conveying rack 4 decreases at a speed that is adapted to the blanking speed of the first loading level, so as to ensure that the number of first gears 1 currently engaged with the first conveying rack 4 is adapted to the magnitude of the force applied by the first conveying rack 4; based on this operation, the number of the first gears 1 engaged with the first conveying rack 4 can be timely reduced without dispersing the applied force of the first conveying rack 4 by too many first gears 1, so that the risk of engagement problems due to too many engagement groups is reduced on the premise of ensuring that the applied force does not exceed the critical bearing capacity of each first gear 1, so that the first gears 1 and the first conveying rack 4 can be operated normally, and the conveying process can be performed smoothly.
When the first conveying rack 4 moves leftwards until the first loading position completely enters the first blanking station 8, all the first target workpieces on the first loading position are completely unloaded, and the first conveying rack 4 is only meshed with the first gear 1 at the leftmost end; at the same time, the second conveying rack 5 has also been moved to the left until the second loading level has completely entered the second loading station 9, the second conveying rack 5 engaging only the leftmost second gearwheel 2. At this time, the corresponding second gear 2 is driven to rotate clockwise through the driving device 3 so as to drive the first conveying rack 4 to move rightwards through the first gear 1, and meanwhile, the second conveying rack 5 is driven to move rightwards through the second gear 2, so that the second loading position gradually leaves the second loading station 9 along with the movement of the second conveying rack 5, and meanwhile, an operator or automatic loading equipment continuously places a second target workpiece on the second loading position at the second loading station 9; as the number of second target workpieces on the second load level increases, the greater the driving force required to drive the second conveying rack 5, i.e., the greater the force exerted by the second conveying rack 5 on the teeth of the second gear 2. While the second loading level is continuously fed, the second conveying rack 5 is also continuously moved rightward to be sequentially re-meshed with the second first gear 1 from the left and the first gear 1 at the rightmost end; in this process, along with the increase of the number of the second gears 2 meshed with the second conveying racks 5, the acting force exerted by the second conveying racks 5 is gradually dispersed to more second gears 2, so that the acting force gradually increased by the continuous feeding of the second conveying racks 5 can be counteracted, the acting force born by the gear teeth of each second gear 2 is ensured not to exceed the critical bearing capacity of the gear teeth, and the problem of tooth slipping is avoided.
When the second loading level completely leaves the second loading station 9, the second loading level is in a full-load state of fully filling the second target workpiece, and as the second conveying rack 5 and the second conveying rack 5 continuously move rightward, the first loading level gradually enters the first loading station 7 on the right side, and the second loading level also gradually enters the second unloading station 10 on the right side, so that the operations are repeated repeatedly in a circulating manner, and the first target workpiece of the first loading station 7 is continuously conveyed to the first unloading station 8, and the second target workpiece of the second loading station 9 is continuously conveyed to the second unloading station 10.
Therefore, in this embodiment, the first target workpiece of the first loading station 7 is stably conveyed to the first unloading station 8, and the second target workpiece of the second loading station 9 is stably conveyed to the second unloading station 10, so that the second gears 2 are not only used for meshing transmission among the first gears 1, thereby fully utilizing each part of the transfer device, realizing bidirectional conveying of the workpiece, and expanding the functions of the transfer device; while the normal conveying of the workpiece is completed, the number of the meshing groups between the first gear 1 and the first conveying rack 4 and the number of the meshing groups between the second gear 2 and the second conveying rack 5 are distributed autonomously and reasonably in the whole conveying process, so that the conveying quality is improved, and the running reliability of equipment is improved; in addition, in the whole conveying process, when one of the first loading position and the second loading position is always kept in a full loading state, the other is necessarily in an empty state, so that damage to the first gear 1, the second gear 2, the first conveying rack 4, the second conveying rack 5 and the driving device 3 caused by overlarge load can be avoided, a protection effect can be formed on the transfer equipment, and the service life of the transfer equipment is prolonged.
Further, referring to fig. 1 and 4, in the third exemplary embodiment, the transfer apparatus includes a mounting base 6 and at least two first rotating shafts 11, the at least two first rotating shafts 11 are slidably connected to the mounting base 6 along the left-right direction, and the first gears 1 are rotatably connected to the first rotating shafts 11 in a one-to-one correspondence.

Specifically, the mounting seat 6 may include two vertical plates disposed at intervals, the first gear 1 and the second gear 2 are both located between the two vertical plates, a sliding groove may be disposed on each vertical plate, the first end of the first rotating shaft 11 and the first end of the second rotating shaft 12 are slidably matched in the sliding groove of one of the vertical plates, and the second end of the first rotating shaft 11 and the second end of the second rotating shaft 12 are slidably matched in the sliding groove of the other vertical plate. The sliding groove may be directly opened on the vertical plate, or may be opened on other members connected to the vertical plate, which is not limited herein. The number of the sliding grooves on each vertical plate can be one or two; when the number of the sliding grooves on each vertical plate is one, the first rotating shaft 11 and the second rotating shaft 12 are both connected in the same sliding groove in a sliding way; when the number of the sliding grooves on each vertical plate is two, the two sliding grooves can be distributed at intervals along the height direction, the first rotating shaft 11 is slidably connected in one sliding groove, and the second rotating shaft 12 is slidably connected in the other sliding groove, so that the rotation center shaft of the first gear 1 and the rotation center shaft of the second gear 2 have a height difference.
Based on the above-mentioned setting, can finely tune the horizontal position of first gear 1, second gear 2 according to the actual application condition conveniently, control the horizontal interval of first gear 1 and second gear 2 in reasonable within range, but simultaneously the relative position of first gear 1 and first transport rack 4 and the relative position of second gear 2 and second transport rack 5 finely tune to this improves the meshing stability between first gear 1, second gear 2, first transport rack 4, the second transport rack 5. After the first gear 1 and the second gear 2 are slidingly adjusted in place, the first rotating shaft 11 and the second rotating shaft 12 can be fixed on the mounting seat 6 through a threaded locking connection, a buckle connection, a pin shaft connection and the like.
Alternatively, referring to fig. 1 and 4, the transfer apparatus includes a first guide bar 13, where the first guide bar 13 is slidably connected to the mounting base 6 along a height direction, the first guide bar 13 is provided with a first chute (not illustrated in the drawings), and at least two first rotating shafts 11 are slidably connected to the first chute along a left-right direction.

Specifically, the mounting seat 6 may be provided with a sliding groove along the height direction, and the first guide bar 13 and the second guide bar 14 may be horizontally placed and slidably matched in the sliding groove through corresponding sliding block structures, so as to realize height adjustment of the first gear 1 and the second gear 2. Simultaneously, the first gear 1 can slide along the first sliding groove horizontally, and the second gear 2 can slide along the second sliding groove horizontally, namely, the horizontal adjustment and the height adjustment of the first gear 1 and the second gear 2 are realized simultaneously.
In practical applications, with reference to the specific conveying process described in the foregoing embodiment, when the feeding speed of the first loading level is faster, so that the acting force applied by the first conveying rack 4 to the first gear 1 increases at a faster speed, there may be a problem that the acting force has reached the critical bearing capacity of the first gear 1 currently engaged with the first conveying rack 4, but the first conveying rack 4 is not yet engaged with the next first gear 1, that is, the acting force cannot be dispersed to more first racks in time; in this case, it is described that the pitch of each first gear 1 is excessively large, and it is necessary to reduce the pitch of each first gear 1 to increase the frequency at which the first conveying rack 4 meshes with the first gear 1, so as to accommodate the increase speed of the urging force. Based on the above-mentioned arrangement, as shown in fig. 4, the second gear 2 may be moved upwards by a certain distance to separate the second gear 2 from the first gear 1, then the first gears 1 are moved horizontally to make each group of two adjacent first gears 1 approach each other, and the first gears 1 and the corresponding second gears 2 are re-meshed at new positions, in this process, the positions of the first gears 1 may also be adapted by moving the second gears 2 horizontally; after the adjustment is finished according to the method, the distance between the first gears 1 can be reduced conveniently without influencing the original action process, so that the frequency of meshing of the first conveying racks 4 and the first gears 1 can be increased, and the increasing speed of acting force can be adapted better.
Similarly, when the feeding speed of the second loading level is higher, so that the acting force applied by the second conveying rack 5 to the second gear 2 increases at a higher speed, there may be a problem that the acting force has reached the critical bearing capacity of the second gear 2 meshed with the second conveying rack 5 at present, but the second conveying rack 5 is not meshed with the next second gear 2 yet, that is, the acting force cannot be dispersed to more second racks in time; in this case, it is described that the pitch of each second gear 2 is excessively large, and it is necessary to reduce the pitch of each second gear 2 to increase the frequency at which the second conveying rack 5 meshes with the second gear 2, so as to accommodate the increase speed of the urging force. Based on the above-mentioned arrangement, as shown in fig. 4, the first gear 1 may be moved downward by a certain distance to separate the first gear 1 from the second gear 2, then the second gears 2 are moved horizontally to make each group of two adjacent second gears 2 approach each other, and the second gears 2 are re-engaged with the corresponding first gears 1 at a new position, in this process, the positions of the second gears 2 may also be adapted by moving the first gears 1 horizontally; after the adjustment is finished according to the method, the distance between the second gears 2 can be conveniently reduced without affecting the original action process, so that the frequency of meshing the second conveying racks 5 with the second gears 2 can be increased, and the increasing speed of acting force can be better adapted.
The above adjusting mode is only used as an example, and can be flexibly set according to actual needs in the specific implementation process, so long as the function of adjusting the gear spacing is finally realized. After the first gear 1 and the second gear 2 are slidingly adjusted in place, the first rotating shaft 11 and the second rotating shaft 12 can be respectively fixed on the first guide strip 13 and the second guide strip 14 by means of threaded locking, snap connection, pin shaft connection and the like, and the first guide strip 13 and the second guide strip 14 are fixed on the mounting seat 6 by means of threaded locking, snap connection, pin shaft connection and the like.

In practical applications, the gear teeth of the first gear 1, the gear teeth of the second gear 2, the gear teeth of the first conveying rack 4, and the gear teeth of the second conveying rack 5 need to be matched in proper positions and angles, so that normal meshing among the first gear 1, the second gear 2, the first conveying rack 4, and the second conveying rack 5 can be ensured, the height positions of the first guide bar 13 and the second guide bar 14 are limited, namely, under the condition that the sizes of the first gear 1, the second gear 2, the first conveying rack 4, and the second conveying rack 5 are fixed, the height difference between the first gear 1 and the second gear 2 needs to be ensured to be within a specified range, and normal meshing among the first gear 1, the second gear 2, the first conveying rack 4, and the second conveying rack 5 can be ensured after the gear positions are adjusted.
Based on the above considerations, in this embodiment, the positions of the first positioning cavity 601 and the second positioning cavity 602 are set in advance, so that when the first spring plunger is in abutting engagement with any one of the first positioning cavities 601 and when the second spring plunger is in abutting engagement with any one of the second positioning cavities 602, the height positions of the first gear 1 and the second gear 2 are within a specified range, and thus, the subsequent fine adjustment work can be omitted, and the adjustment efficiency is improved.
