Description

Technical Field

[0001] This utility model relates to the field of tire production equipment, and in particular to a mold placement tray that is used in conjunction with AGVs or other handling tools on tire vulcanizing machines. Background Technology

[0002] Existing tire vulcanization processes involve placing raw tires into tire molds (including upper and lower molds) for vulcanization. When producing tires of different specifications or when the tire molds require maintenance, the old molds need to be removed from the vulcanizing machine and replaced with new ones. Current methods rely on manual mold replacement, which is extremely inconvenient and inefficient due to the large size and weight of the molds, and also poses safety hazards. Therefore, this invention provides a mold placement tray that works in conjunction with AGVs or other transport tools on a tire vulcanizing machine. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a mold placement tray for use on a tire vulcanizing machine, including a main support component. The main support component is provided with a accommodating space for accommodating transport tools. A centering component for centering the tire mold is provided at the end of the main support component that contacts the tire mold. A first positioning component is provided at the end of the main support component that is away from the tire mold.

[0004] Preferably, the centering component has a centering surface that mates with the bottom of the tire mold.

[0005] Preferably, the centering element is a hollow annular structure.

[0006] Preferably, the midpoint surface is a circular surface.

[0007] Preferably, the first positioning element is a hollow structure, and a first guide end and a first positioning end are provided inside the first positioning element.

[0008] Preferably, the first positioning member is disposed within the main support member, and the main support member is provided with a mounting hole, the mounting hole including a first mounting end for mounting the first positioning member and a clearance end.

[0009] Preferably, it also includes a heat insulation component, which is disposed on the main support component at one end near the tire mold.

[0010] Preferably, it further includes a protective layer disposed above the heat insulation element.

[0011] Preferably, it also includes an adjusting member sleeved outside the centering member.

[0012] Preferably, the first positioning element and the main support element can be integrally set or separately set.

[0013] This invention primarily designs a mold placement tray for use on a tire vulcanizing machine, enabling automatic loading and unloading of tire molds in conjunction with AGVs or other handling tools. By setting a centering component and a first positioning component to position the tire mold and the tire vulcanizing machine respectively, the positioning of the mold placement tray is made more precise, thus enabling the placement of the tire mold on the tray and the tray into the tire vulcanizing machine. The first positioning component, having a first guide end and a first positioning end, better cooperates with the positioning mechanism within the tire vulcanizing machine for positioning. The first positioning component is housed within the support main component via a setting hole, a first mounting end, and a clearance component, achieving a more rational layout.

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0032] like Figures 1 to 17As shown, this utility model provides an AGV-based tire vulcanizing system. The tire vulcanizing system includes a tire vulcanizing machine 100 with a tire mold 40, and an AGV that can transport the tire mold 40 between the tire vulcanizing machine 100 and a designated location. The tire vulcanizing machine 100 includes a tire frame 10, a lifting mechanism 20 mounted on the tire frame, an upper template assembly 31 movably mounted on the tire frame 10 via the lifting mechanism 20, and a lower template assembly 32 opposite to the upper template assembly 31. The upper template assembly 31 has an upper mold 41, and the lower template assembly 32 has a lower mold 42. The lower template assembly 32 also has a positioning mechanism 50. It also includes a mold placement tray 200 that cooperates with the positioning mechanism 50. The mold placement tray 200 is transported by the AGV and used to load the tire mold 40. In this utility model, the tire mold 40 refers to the upper mold 41 and the lower mold 42 combined as one unit. The lifting mechanism 20 is a driving mechanism that can drive the upper template assembly 31 to move up and down. It can be driven by electricity, hydraulic force, or other methods. The lifting mechanism 20 can be installed on the upper template assembly 31, on the tire frame 10, or in other locations. The attached figure only illustrates the electric drive method installed on the upper template assembly 31.

[0033] The tire vulcanizing machine 100 with the above-described structure, in conjunction with an AGV and a mold placement tray 200, enables the automatic removal of the old tire mold from the vulcanizing machine 100 and the loading of the new tire mold when different specifications of the tire mold 40 need to be replaced or when the tire mold needs maintenance. The automatic mold removal and loading method based on AGV described in this invention can be used alone or simultaneously.

[0034] The upper template assembly 31 of this utility model can be an upper template or an upper template with an upper heating element, etc., and the lower template assembly 32 can be a lower template or a lower template with a lower heating element, etc.

[0035] This utility model provides an automatic demolding method for a tire vulcanizing machine based on AGV, including the following steps: S11: as Figure 2 and 3 As shown, the original tire mold located on the tire vulcanizing machine 100 is lifted to the upper mold changing station by the lifting mechanism 20 of the tire vulcanizing machine. The upper mold changing station refers to the position after the tire mold 40 is raised as a whole. This position is used to avoid the AGV, so that the AGV can extend into the tire vulcanizing machine 100.

[0036] S12: As Figure 4As shown, the empty mold placement tray 200 is transported to the lower mold changing station by an AGV. The lower mold changing station refers to the position used to load the mold placement tray 200.

[0037] S13: Precisely position the mold placement plate 200 with the positioning mechanism 50 of the tire vulcanizing machine.

[0038] S14: As Figure 5 As shown, the original tire mold located at the upper mold changing station is moved to the mold placement plate 200 by the lifting mechanism 20 and the original tire mold is released.

[0039] S15: As Figure 6 and 7 As shown, the AGV moves the mold placement tray 200, which contains the original tire mold, out of the tire vulcanizing machine 100.

[0040] By using the above method, the tire vulcanizing machine 100 in conjunction with the AGV can automatically unmold the tire mold 40, replacing the original manual unmolding, thereby achieving rapid mold replacement and reducing the intensity of manual operation.

[0041] It should be noted that during normal production, the upper mold 41 and lower mold 42 are respectively mounted on the upper template assembly 31 and the lower template assembly 32. Before demolding the tire mold 40, the separated upper mold 41 and lower mold 42 need to be combined into a whole tire mold 40. Preferably, step S111 is included before step S11: as follows Figure 1 and 2 As shown, the lifting mechanism 20 moves the upper mold 41 to the position of the lower mold 42, so that the upper mold 41 and the lower mold 42 are combined into a whole tire mold 40. The lower mold 42 is then automatically released by the lower mold locking device 60, so that the lower mold 42 is no longer fixed to the lower template assembly 32. The release step of the lower mold 42 and the step of combining the upper mold 41 and the lower mold 42 into a whole tire mold 40 can be performed sequentially or simultaneously, depending on specific production needs. The tire mold 40 described in this invention can be assembled or separated manually by the upper mold 41 and the lower mold 42, or automatically by a mechanical structure or a robotic arm. The lower mold locking device 60 described in this invention can be any structure that can automatically lock and separate the lower mold 42 from the lower template assembly 32.

[0042] In step S14, the existing tire mold 40 located at the upper mold changing station is moved to the position of the mold placement plate 200 by the lifting mechanism 20, and the tire mold 40 is placed on the mold placement plate 200. At the same time, the upper mold 41 is automatically released by the upper mold locking device 70, so that the upper mold 41 and the upper template assembly 31 are automatically separated. The upper mold 41 is in a free state, and the tire mold 40 is finally separated from the upper template assembly 31, so that the tire mold 40 is placed on the mold placement plate 200. Of course, the upper mold 41 and the upper template assembly 31 can also be automatically locked by the upper mold locking device 70. The upper mold locking device 70 only needs to be able to achieve automatic locking and separation of the upper mold 41 and the upper template assembly 31.

[0043] Step S15 may be followed by step S16, in which the AGV moves the mold placement tray 200 containing the original tire mold to a designated location to temporarily store the original tire mold.

[0044] This utility model also provides an automatic mold loading method for a tire vulcanizing machine based on AGV, including the following steps: S21: as Figure 6 As shown, the mold placement tray 200 carrying the new tire mold is transported to the next mold changing station by an AGV.

[0045] S22: As Figure 5 As shown, the mold placement plate 200 is precisely positioned with the positioning mechanism 50 of the tire vulcanizing machine, and the new tire mold is locked with the upper template assembly 31.

[0046] S23: As Figure 4 As shown, the new tire mold is lifted to the upper mold changing station by the lifting mechanism 20, so that the AGV can unload the mold placement tray 200.

[0047] S24: The AGV removes the empty mold placement tray 200 from the tire vulcanizing machine.

[0048] S25: As Figure 3 and 2 As shown, the new tire mold is lowered to the mold assembly station by the lifting mechanism 20, so that the tire mold 40 contacts the lower template assembly 32 and is placed on the lower template assembly 32. The mold assembly station refers to the position used to place the tire mold 40 on the lower template assembly 32.

[0049] S26: Lock and fix the lower mold 42 to the lower template assembly 32.

[0050] The process includes step S211 before step S21: retrieving a mold placement tray 200 containing the new tire mold from a designated location using an AGV. The designated location can be a mold warehouse or storage facility where the tire mold 40 is temporarily stored.

[0051] Preferably, the tire vulcanizing system of this utility model may further include a preheating device (not shown), which is used to preheat the new tire molds to be loaded onto the tire vulcanizing machine 100. By preheating the new tire molds, the time required for the new tire molds to go from cold equipment to normal production is shortened, thereby improving production efficiency. Therefore, another embodiment of step S211 is that an AGV takes a mold placement tray 200 loaded with new tire molds from the preheating device, which has already been preheated by the preheating device.

[0052] Preferably, to ensure that the AGV transports the mold placement tray 200 containing the new tire mold to the lower mold changing station, the upper mold assembly 31 will not interfere at the lower mold changing station. Before step S21, a detection and judgment step S212 for the upper mold assembly 31 is also included: Figure 7 As shown, the system detects whether the upper template assembly 31 is at the upper mold changing station. If the upper template assembly 31 is not at the upper mold changing station, the lifting mechanism 20 lifts the upper template assembly 31 to the upper mold changing station. This prevents the upper template assembly 31 from colliding with the AGV and mold placement tray 200 at the lower mold changing station and damaging the equipment.

[0053] It should be noted that there is no necessary order requirement for steps S211 and S212 above. The order can be set according to actual needs or they can be performed simultaneously.

[0054] In step S22, the upper template assembly 31 is moved to contact the new tire mold by the lifting mechanism 20, and the new tire mold is automatically locked and fixed to the upper template assembly 31 by the upper mold locking device 70. At this time, the upper mold locking device 70 automatically locks the new tire mold to the upper template assembly 31 by automatically locking the upper mold 41 in the new tire mold to the upper template assembly 31.

[0055] Preferably, to ensure that the upper mold 41 is in contact with the upper template assembly 31 when automatically locking the upper mold 41 and the upper template assembly 31, step S22 further includes a mold positioning detection and judgment step S221: a detection mechanism (not shown) detects and determines whether the upper template assembly 31 is in contact with the new tire mold. Once the detection determines that the upper template assembly 31 is in contact with the tire mold 40, the new tire mold is automatically locked to the upper template assembly 31. Preferably, the detection mechanism includes a movable trigger element mounted on the upper template assembly 31, the trigger element protruding from the end face of the upper template assembly 31 near the upper mold. It also includes a detection element that, when the upper template assembly 31 contacts the tire mold 40, causes the trigger element to move. The detection element detects the positional change of the trigger element and feeds this positional change back to the control system, thereby determining whether the upper template assembly 31 is in contact with the tire mold 40.

[0056] Preferably, in step S26, the lower mold 42 and the lower template assembly 32 are automatically locked and fixed by the lower mold locking device 60, thereby realizing the automatic locking of the lower mold 42 onto the lower template assembly 32.

[0057] The automatic mold-upper method of this utility model further includes a tire mold 40 separation step S261: separating the tire mold 40 into an upper mold 41 and a lower mold 42, that is, the upper mold 41 and the lower mold 42 are no longer fixed together and can move separately. The tire mold separation step S261 can occur before step S26, in which case the lower mold 42 in step S26 is a separate lower mold 42 after being separated from the upper mold 41. That is, the tire mold is separated first, and then the lower mold 42 is locked and fixed to the lower template assembly 32.

[0058] In another implementation, the tire mold separation step S261 can also occur after step S26. In this case, the lower mold 42 in step S26 is the upper mold 41 in the tire mold 40 that is still connected to the upper mold. That is, the lower mold 42 in the overall tire mold is first locked and fixed to the lower template assembly 32, and then the tire mold 40 is separated so that the upper mold 41 can move independently.

[0059] like Figures 8 to 11As shown, the mold placement tray 200 of this utility model includes a supporting main component 210. The supporting main component 210 is provided with a accommodating space 211 for placing AGVs or other handling tools. The handling tools can use the accommodating space 211 to pick up and put down the mold placement tray 200. A centering component 220 is provided on the end of the supporting main component 210 that contacts the tire mold 40 for centering the lower mold 42 in the tire mold. A plurality of first positioning components 230 are also provided on the end of the supporting main component 210 away from the contact with the tire mold. The first positioning components 230 cooperate with the positioning mechanism 50 on the lower template assembly 32 of the tire vulcanizing machine, so that when the mold placement tray 200 is placed in the tire vulcanizing machine for picking up and putting down the tire mold 40, the position of the mold placement tray 200 is fixed. The first positioning components are arranged opposite to the positioning mechanism, and the number of first positioning components can be one or more.

[0060] like Figure 10 As shown, the centering component 220 has a centering surface 221 that mates with the bottom of the lower mold 42. Preferably, the centering component 220 can be cylindrical or a hollow annular structure. When the centering component is a hollow annular structure, it can effectively reduce the total weight of the entire mold placement tray. The centering surface 221 is a circular surface, which better mates with the circular bottom of the lower mold 42, so that when the tire mold 40 is placed on the mold placement tray 200, the tire mold 40 is fixed and will not move. It should be noted that when the centering surface 221 mates with the bottom of the lower mold 42, the tire mold 40 will not move left or right, but the tire mold 40 can easily move upward, that is, the tire mold 40 can easily separate from the centering component 220.

[0061] like Figure 9 As shown, preferably, the first positioning member 230 has a hollow structure, and a first guide end 231 for guiding the positioning mechanism 50 and a first positioning end 232 that cooperates with the positioning mechanism 50 are provided inside the first positioning member 230. When the mold placement tray 200 is placed from top to bottom on the positioning mechanism 50 of the tire vulcanizing machine 100 or the temporary storage position, the positioning mechanism 50 is guided into the first positioning member 230 by the first guide end 231, so that the first positioning end 232 makes good contact with the positioning mechanism 50 for positioning.

[0062] like Figure 10 and 11As shown, preferably, for a more reasonable layout, the first positioning member 230 is disposed within the support main member 210. The support main member 210 has a mounting hole 212, which has a first mounting end 2121 for mounting the first positioning member 230 and a clearance end 2122 for accommodating the positioning mechanism 50. When the mold placement tray 200 is placed on the positioning mechanism 50, the positioning mechanism 50 is guided by the first guide end 231 and positioned within the first mounting end 2121 of the first positioning member and the clearance end 2122 of the mounting hole. The first positioning member 230 can be integrally disposed with the support main member 210 or separately disposed.

[0063] It should be noted that existing tire molds unloaded from the tire vulcanizing machine are typically at a certain temperature. To prevent automated guided vehicles (AGVs) from being damaged by the temperature of the tire mold 40, the mold placement tray 200 of this invention also includes a heat insulation component 240, which is disposed on the main support component 210 near the end of the tire mold 40. The heat insulation component 240 is made of heat-insulating material, thereby preventing the temperature of the tire mold 40 from being transferred downwards to the AGV or handling equipment. Furthermore, when a new tire mold is replaced on the tire vulcanizing machine after preheating, loading and transporting the new tire mold using the mold placement tray 200 with the heat insulation component 240 effectively prevents the temperature of the new tire mold from dropping due to energy transfer.

[0064] Because the mold is heavy and the material is hard, in order to prevent the heat insulation material from being crushed or scratched by the mold, the mold placement tray 200 of this utility model is also provided with a protective layer 250 with a certain hardness. The protective layer 250 is disposed above the heat insulation component 240 and is used to contact the tire mold 40.

[0065] like Figure 10 As shown, since the specifications of molds produced by different tire mold manufacturers 40 are not exactly the same, that is, the inner diameter of the circular bottom of the lower mold will change, in order to make the mold placement plate 200 have a better range of use, the mold placement plate 200 of this utility model also includes an adjusting member 260 sleeved outside the centering member 220. Preferably, the adjusting member 260 is a ring structure. When the inner diameter of the circular bottom of the lower mold 42 in the tire mold 40 changes, by replacing the adjusting member 260 with one of different sizes, the adjusting member 260 and the bottom of the lower mold 42 can better match to achieve position centering.

[0066] like Figure 8 and 9As shown, preferably, the positioning mechanism 50 of this utility model includes a plurality of second positioning components 51. Each second positioning component 51 includes a second mounting end 511, a second positioning end 512 that cooperates with the mold placement plate 200, and a second guide end 513. Preferably, the second positioning end 512 is cylindrical and the second guide end 513 is conical.

[0067] like Figures 12 to 14 As shown, preferably, the lower mold locking device 60 of this utility model includes a lower locking drive mechanism 61 and a plurality of lower locking mechanisms 62 driven by the lower locking drive mechanism 61 (the plurality of mechanisms also includes one lower locking mechanism 62, which can be driven by an independent lower locking drive mechanism 61). The lower template assembly 32 is provided with a plurality of lower template locking grooves 311. The lower locking mechanism 62 can move within the lower template locking groove 311 driven by the lower locking drive mechanism 61, thereby automatically locking or releasing the lower mold 42 placed on the lower template assembly 32.

[0068] like Figure 12 and 13 As shown, the lower locking drive mechanism 61 includes a lower locking drive source 611 and a first transmission mechanism 612 driven by the lower locking drive source 611. The first transmission mechanism 612 includes a first transmission member 6121 disposed along the circumference of the lower template assembly 32 and within the lower template locking groove 311, and a second transmission member 6122 disposed within the lower template locking groove 311. The first transmission member 6121 and the second transmission member 6122 are coupled together. Preferably, the first transmission member 6121 is a chain or steel cable, and the second transmission member 6122 is a gear or sprocket. Several lower locking mechanisms 62 are fixed to the second transmission member 6122 at the same distance position in the lower template locking groove 311. When the lower locking drive source 611 drives the second transmission member 6122 to move, the second transmission member 6122 drives several lower locking mechanisms 62 to move synchronously, thereby realizing that the first transmission mechanism 612 drives several lower locking mechanisms 62 to move synchronously in the lower template locking groove 311.

[0069] like Figure 14 As shown, the lower locking mechanism 62 includes a support member 621 and a locking member 622 that is parallel to the support member 621 at a certain distance via a spacing adjustment member 624. The locking member 622 is connected to the support member 621 via an elastic component 623. After the locking member 622 contacts the lower mold 42, it can be lifted upward relative to the support member 621 and subjected to a downward clamping force. Thus, the downward clamping force on the locking member 622 locks the portion of the lower mold 42 and the lower template assembly 32 located between the support member 621 and the locking member 622.

[0070] The elastic component 623 includes a fixed shaft 6231 that passes through the support member 621. The fixed shaft 6231 can move within the support member 621. The fixed shaft 6231 is connected to the locking member 622. The fixed shaft 6231 has a fixed shaft end 6232 at one end near the support member 621. The component also includes a fastener 6233 that fixes the fixed shaft 6231 to the locking member 622. The elastic component 623 further includes a first elastic element 6234 sleeved on the fixed shaft 6231. The first elastic element 6234 is disposed between the support member 621 and the fixed shaft end 6232. When the locking member 622 contacts the lower mold 42, and is lifted upwards by the force of the lower mold 42, the locking member 622 drives the fixed shaft 6231 to move upwards. This causes the first elastic element 6234, located between the support member 621 and the end of the fixed shaft 6232, to be compressed. Since the support member 621 is located within the lower mold assembly 32 and cannot move upwards, the elastic restoring force of the first elastic element 6234 acts on the fixed shaft 6231 through the end of the fixed shaft 6232, causing the fixed shaft 6231 to be subjected to a downward force. Through the transmission of force, the locking member 622 is subjected to a downward force, thereby locking the support member 621 and the locking member 622. Preferably, the first elastic element 6234 is a compression spring.

[0071] like Figures 15 to 17As shown, preferably, the upper mold locking device 70 of this utility model includes an upper locking drive source 711, a movable sliding seat 72 connected to the upper locking drive source 711, and a clamping mechanism 73 connected to the sliding seat 72. The clamping mechanism 73 includes a first clamping member 731 and a second clamping member 732 that are movably disposed along a first direction (e.g., horizontal direction F1). The first clamping member 731 can also move along a second direction (e.g., vertical direction F2). The first clamping member 731 is provided with a first locking groove 7311, and the second clamping member 732 is provided with a second locking groove 7321. The first locking groove 7311 and the second locking groove 7321 are disposed opposite to each other. Clamping member 731 and second clamping member 732 can move simultaneously towards each other or in opposite directions along the first direction F1. When the first clamping member 731 reaches the locking position along the first direction (the locking position refers to the position in the first direction F1 where the first locking groove 7311 on the first clamping member 731 is in complete contact with the mold locking screw 312, which is pre-fixed on the upper mold 41 of the tire mold and passes through the upper template assembly 31, and in this position the first clamping member 731 cannot continue to move towards the second clamping member 732 in the first direction F1), the second clamping member 732 continues to move along the first direction F1, driving the first clamping member 731 to move along the second direction F2. When the first clamping member 731 moves along the second direction to fully contact the locking end of the mold-locking screw 312, so that the upper mold 41 contacts the upper template assembly 31 in the second direction, the first clamping member 731 and the second clamping member 732 lock the mold-locking screw 312 passing through the upper template assembly 31 in the second direction, thereby realizing automatic mold locking of the upper mold 41.

[0072] like Figure 16 As shown, the first clamping member 731 is provided with a first inclined surface 7312, and the second clamping member 732 is provided with a second inclined surface 7322. The first inclined surface 7312 and the second inclined surface 7322 are arranged parallel to each other. With this arrangement, when the first clamping member 731 reaches the locking position, the second clamping member 732 continues to move along the first direction toward the first clamping member 731 until it contacts the first clamping member 731. At this time, the second inclined surface 7322 of the second clamping member 732 contacts the first inclined surface 7312 of the first clamping member 731. Since the first clamping member 731 can no longer move toward the second clamping member 732 in the first direction F1, when the second clamping member 732 continues to move toward the first clamping member 731, the first inclined surface 7312 of the first clamping member moves upward along the second direction F2 under the guidance of the second inclined surface 7322 of the second clamping member, thus realizing the movement of the first clamping member 731 along the second direction.

[0073] like Figure 15As shown, the first clamping member 731 is connected to the sliding seat 72 through the first connecting mechanism 74, and the second clamping member 732 is connected to the sliding seat 72 through the second connecting mechanism 75. It also includes a moving adjustment mechanism 76 disposed on the first connecting mechanism 74. The moving adjustment mechanism 76 is used to ensure that when the first clamping member 731 reaches the locking position, the first clamping member 731 does not move in the first direction F1, while the second clamping member 732 continues to move in the first direction.

[0074] Specifically, the first connecting mechanism 74 includes a hinged linkage assembly 741 and a rotating rod 742, and a support rod 743 connected to the middle of the rotating rod 742. The rotating rod 742 is rotatably mounted on the support rod 743. The end of the linkage assembly 741 away from the hinged connection with the rotating rod 742 is hinged to a sliding seat 72, and the end of the rotating rod 742 away from the hinged connection with the linkage assembly 741 is hinged to a first clamping member 731. The second connecting mechanism 75 is hinged to the sliding seat 72 and the second clamping member 732, respectively. The linkage assembly 741 includes a fixed rod 7411 and a movable rod 7412, with one end of the movable rod 7412 movably mounted within the fixed rod 7411. The movable adjustment mechanism 76 includes a movable groove 761 disposed on a fixed rod 7411, and a fixing member 762 movable within the movable groove 761 and fixedly disposed on a movable rod 7412. The fixing member 762 causes the movable rod 7412 to move within the range of the movable groove 761. It also includes a second elastic element 763 sleeved on the movable rod 7412. The second elastic element 763 is disposed on a portion of the movable rod 7412 located outside the fixed rod 7411. When the movable rod 7412 moves toward the fixed rod 7411, it compresses the second elastic element 763.

[0075] Preferably, the upper locking drive source 711 of this utility model can be an independent drive source to drive a clamping mechanism, such as... Figure 17 As shown, in another embodiment, a second transmission mechanism 712 driven by an upper locking drive source 711 is also included. The second transmission mechanism 712 drives multiple sets of clamping mechanisms 73 to move synchronously, simultaneously locking multiple locking screws 312. Preferably, the second transmission mechanism 712 includes a gear 7121 and a first rack 7122 and a second rack 7123 respectively meshing with the gear 7121. It also includes a first connecting rod 7124 connected to the first rack 7122 and a second connecting rod 7125 connected to the second rack 7123. The first connecting rod 7124 and the second connecting rod 7125 are respectively connected to two sets of sliding seats 72. This configuration enables a single upper locking drive source 711 to drive multiple clamping mechanisms 73 to move synchronously.
