DETAILED DESCRIPTION

[0018] To make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0019] The umbrella box sealing machine provided in the embodiments of the present application can solve the problem that the sealing machine in the prior art adopts a traditional fixed structure and is difficult to adapt to umbrella boxes of different specifications and materials, thereby limiting the application range and operation flexibility.

[0020] As shown in FIG. 1, an umbrella box sealing machine comprises: Figures 1 to 4 a box body 1, an upper end of which is provided with an opening; a pressing plate 2 arranged at the opening of the box body 1; a first adjusting plate 3 arranged in the box body 1; two second adjusting plates 4 arranged in the box body 1 respectively; a first adjusting mechanism 5 connected with the first adjusting plate 3 and used for driving the first adjusting plate 3 to move along the width direction of the box body 1; a second adjusting mechanism 6 connected with the two second adjusting plates 4 and used for driving the two second adjusting plates 4 to move closer to or away from each other along the length direction of the box body 1; a power mechanism 8 connected with the box body 1 and used for driving the box body 1 to move along the height direction. The umbrella box sealing machine provided in the embodiments of the present application can flexibly adjust the length and width of the internal accommodating space by arranging the first adjusting plate 3 and the second adjusting plate 4 and respectively equipping independent driving mechanisms, so as to adapt to umbrella boxes of different sizes and specifications and improve the versatility and utilization rate of the equipment. The second adjusting mechanism 6 can simultaneously drive the two second adjusting plates 4 to move closer to or away from each other, which is not only convenient to operate but also can ensure the symmetrical adjustment of the internal space of the box body 1. The power mechanism 8 drives the box body 1 to move upward, so as to vertically compress and press the umbrella box placed in the box body 1.

[0021] Further, the first adjusting mechanism 5 comprises:

[0022] a first transmission rod 501 arranged along the width direction of the box body 1, one end of which is fixedly connected with the first adjusting plate 3, the other end of which is threadedly connected with the box body 1, and the end far away from the first adjusting plate 3 is fixedly connected with a rotating wheel. In the embodiment, the first transmission rod 501 is a ball screw.

[0023]

[0024] ​In some optional embodiments, the first transmission rod 501 is a screw rod.

[0025] By rotating the rotating wheel, the first transmission rod 501 can be driven to produce axial displacement under the action of threads, thereby driving the first adjusting plate 3 to translate along the width direction of the box body 1, and realizing pressure maintaining on the umbrella box side walls in the box body 1.

[0026] Further, the second adjusting mechanism 6 comprises: Two bidirectional screw rods 601 are provided, which are arranged in parallel along the length direction of the box body 1, the threads at the two ends of each bidirectional screw rod 601 are opposite and symmetrical along the center; Two connecting plates 602 are provided, which are arranged along the width direction of the box body 1 respectively, the two ends of each connecting plate 602 are threadedly connected with one bidirectional screw rod 601 respectively, and each connecting plate 602 is connected with one second adjusting plate 4; A plurality of guide blocks 603 are provided, which are slidably connected with the box body 1 along the width direction, each bidirectional screw rod 601 passes through at least one guide block 603 and is slidably connected with the guide block 603.

[0027] By simultaneously rotating the bidirectional screw rods 601, the two connecting plates 602 are synchronously moved to the center due to the symmetrical threads, thereby driving the two second adjusting plates 4 to synchronously move to the center and maintaining the pressure on the other two side walls of the umbrella box in the box body 1. At the same time, due to the symmetrical transmission characteristics of the bidirectional screw rods 601, the position of the umbrella box can be automatically corrected during the synchronous movement of the two second adjusting plates 4, so as to ensure that it is in the centered state. Compared with the design of adjusting screw rods arranged in multiple directions in the traditional way, the two sides can be synchronously adjusted and centered by the bidirectional screw rods in the present application, which greatly improves the adjusting efficiency.

[0028] Further, the opposite side walls of the box body 1 are provided with through holes 101, the connecting plates 602 pass through the through holes 101 and are hingedly connected with the second adjusting plates 4 through hinge pieces.

[0029] In the process of the second adjusting plate 4 pressing the umbrella box side wall, if there is a slight tilt or unevenness in the umbrella box side wall, or the initial resistance of the two side walls is different, the hinged structure can allow the second adjusting plate 4 to produce a slight angle adaptive adjustment around the hinge point, that is, the second adjusting plate 4 can dynamically adjust the pressing angle according to the actual shape of the umbrella box side wall, to avoid local pressure concentration caused by fixed force direction; at the same time, this hinged cooperation can also uniformly convert the axial thrust transmitted by the connecting plate 602 into a surface contact pressure of the second adjusting plate 4 on the umbrella box side wall, rather than a local point / line pressure. On the one hand, it can effectively balance the stress of the two side walls of the umbrella box, prevent the umbrella box from being deformed or damaged due to excessive local pressure, and ensure the safety of the pressure maintaining process; on the other hand, even if there is a slight deviation in the initial placement of the umbrella box in the box body 1, the adaptive characteristics of the hinged structure can ensure that the second adjusting plate 4 and the umbrella box side wall always maintain stable fitting, thereby improving the reliability of pressure maintaining.

[0030] Further, the connecting plate 602 is provided with a recess 6021 at both ends, and a pin shaft 604 is rotatably connected in the recess 6021. The pin shaft 604 is parallel to the height of the box body 1, and the bidirectional screw rod 601 is threadedly connected with the pin shaft 604.

[0031] Since the two bidirectional screw rods 601 need to rotate synchronously, if the bidirectional screw rod 601 is directly threadedly connected with the connecting plate 602, the perpendicularity of the screw rod axis and the connecting plate 602 must be strictly ensured, otherwise the thread may be jammed or excessively worn due to synchronization deviation; and through the cooperation of the pin shaft 604 and the recess 6021, a small angle adjustment space can be provided for the structure, so as to flexibly adapt to the deviation between the bidirectional screw rod 601 and the connecting plate 602, effectively reduce the mechanical stress concentration, and further prolong the service life of the components.

[0032] Further, the third adjusting mechanism 7 comprises: Two vertical columns 701 are vertically and fixedly connected with the base 801 on both sides of the box body 1; A horizontal beam 702 is arranged between the two vertical columns 701, and both ends of the horizontal beam 702 are fixedly connected with the top ends of the vertical columns 701; A second transmission rod 703 is arranged in a vertical direction, and the upper part of the second transmission rod 703 is threadedly connected with the horizontal beam 702, and the lower end of the second transmission rod 703 is fixedly connected with the pressing plate 2. In the embodiment, the second transmission rod 703 is a ball screw. In some optional embodiments, the second transmission rod 703 is a screw rod.

[0033] The third adjusting mechanism 7 supports the cross beam 702 through two columns 701, and the second transmission rod 703 is threadedly connected with the cross beam in the vertical direction, so that the second transmission rod 703 can drive the pressing plate 2 to move in the vertical direction, fix the position of the pressing plate 2, and pre-establish the relative action distance between the pressing plate 2 and the box 1, thereby not only assisting the power mechanism 8 to complete the pressure adjustment of the umbrella box, but also effectively compensating for the limitation of the working stroke.

[0034] Further, a plurality of first adjusting holes 704 are arranged on the column 701 in the height direction; The third adjusting mechanism 7 further comprises: The sleeve 705 is sleeved on the column 701, the sleeve 705 is provided with a second adjusting hole 706, and the two ends of the cross beam 702 are fixedly connected with the top ends of the two sleeves 705, respectively. The bolt 707 is used for inserting into the second adjusting hole 706 and the selected first adjusting hole 704, so as to fix the sleeve 705 on the column 701.

[0035] In order to compensate for the insufficient stroke of the second transmission rod 703, a plurality of first adjusting holes 704 are arranged on the column 701 in the height direction, and the sleeve 705 sleeved on the column 701, the second adjusting hole 706 on the sleeve 705 and the bolt 707 are configured, so that the cross beam 702 is adjustably connected with the column 701 through the sleeve 705. When the adjusting stroke of the second transmission rod 703 cannot meet the height requirement of the pressing plate 2, the bolt 707 is pulled out, the sleeve 705 is moved to a suitable position along the column 701 in the height direction, the second adjusting hole 706 on the sleeve 705 is aligned with the first adjusting hole 704 at the corresponding height on the column 701, and then the bolt 707 is inserted again, so that the overall height of the cross beam 702 is adjusted, and the actual adjusting range of the pressing plate 2 driven by the second transmission rod 703 is expanded. This design not only retains the fine pressure adjustment function of the second transmission rod 703 (whether it is a ball screw or a screw) through the threaded connection, but also realizes the height adjustment of a larger range through the cooperation of the sleeve and the column. The combination of the two can make the power mechanism 8 adapt to a wider pressure adjustment requirement.

[0036] Further, the connecting plate 602 is provided with a first guide hole 6022 extending in the length direction of the box 1, and the column 701 penetrates the first guide hole 6022.

[0037] This design makes the column 701 and the connecting plate 602 form a penetrating cooperation, which not only ensures that the column 701 stably supports the third adjusting mechanism, but also effectively reduces the space occupation volume of the two, so that the overall structure layout is more compact.

[0038] Further, a plurality of second guide holes 102 are arranged on the side wall of the box 1. The first adjusting plate 3 and the second adjusting plate 4 are both provided with a guide column 9, the guide column 9 is inserted into the second guide hole 102 and can slide along the second guide hole 102, the diameter of the second guide hole 102 is larger than the diameter of the guide column 9, so that the first adjusting plate 3 and the second adjusting plate 4 can be partially fine-tuned.

[0039] Further, the power mechanism 8 comprises: a base 801, the box 1 is vertically slidably connected to the base 801; a motor 802, fixedly connected to the base 801; a worm screw elevator 803, the output end of which is connected to the box 1; a sprocket chain mechanism 804, one end of a large sprocket thereof is fixedly connected to the input end of the worm screw elevator 803, and one end of a small sprocket is fixedly connected to the output end of the motor, the large sprocket and the small sprocket are connected by a chain transmission; a pressure sensor 805, arranged at the output end of the worm screw elevator 803.

[0040] Since the box 1 is arranged on the base 801 and is vertically slidably connected to the stand column 701, when the motor 802 is started, the power is transmitted to the input end of the worm screw elevator 803 through the sprocket chain mechanism 804 (small sprocket, chain, large sprocket transmission in turn), driving the worm screw elevator 803 to operate, and the output end of the worm screw elevator 803 drives the box 1 to slide in the vertical direction along the base 801 and the stand column 701; at the same time, the pressure sensor 805 can monitor the driving force of the output end of the worm screw elevator 803 to the box 1 in real time, so as to adjust the pressure according to the requirement, and the worm screw elevator 803 itself has a self-locking function, which can keep the position of the box 1 when the box 1 stops moving, realizing pressure maintaining. Through the cooperation of the motor driving and the sprocket chain transmission, the vertical movement of the box 1 is realized, meeting the pressure adjustment requirement of the umbrella box in the box 1; the self-locking function of the worm screw elevator 803 can prevent the box 1 from moving accidentally due to external force or self-weight in the stopped state, realizing the stability of the pressure; the setting of the pressure sensor 805 can accurately monitor and adjust the driving force, meeting the requirement when the pressure is applied to the umbrella box, improving the accuracy and reliability of the operation of the equipment.
