[0042] The features and performance of the paper roll installation mechanism of the present application are further described in detail below in conjunction with the embodiments.

[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a battery cell conveying mechanism, which includes a rotatable turntable 500, a DD motor 510 for driving the turntable 500 to rotate, and four workbenches 400 connected to the turntable 500. The four workbenches 400 are arranged at intervals along the circumference of the turntable 500. Each workbench 400 is connected to two paper roll mounting mechanisms and a motor assembly 600 corresponding to the paper roll mounting mechanisms. Each workbench 400 is fixed with two paper roll rollers 100 through the two paper roll mounting mechanisms. The two paper roll mounting mechanisms are respectively used to fix the corresponding paper roll rollers 100. The paper roll roller 100 is provided with a clamping hole 110 running through the center of both ends thereof. The paper roll mounting mechanism includes a clamping hole 110 respectively connected to the paper roll rollers The fixed component 200 and the movable component 300 are connected at both ends of 100, and the fixed component 200 and the movable component 300 are both installed on the turntable 500 and can rotate freely; the motor component 600 is fixed on the turntable 500 by screws and is connected to the fixed component 200 of the corresponding roll paper installation mechanism by the belt wheel component 610. When the motor component 600 is started, the corresponding fixed component 200 is driven to rotate through the belt wheel component 610, thereby driving the roll paper roller 100 connected to the corresponding roll paper installation mechanism and the roll paper 101 sleeved on the roll paper roller 100 to rotate, thereby rolling up the roll paper 101 and driving the battery cell 520 on the workbench 400 along the winding direction of the roll paper 101, that is, the direction of the arrow;

[0044] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13 , Fig.14 and Fig.15As shown, the fixing assembly 200 includes a fixing pin 210 for engaging with the engaging hole 110 at one end of the paper roller 100 and a shaft rod 220 connected to the fixing pin 210 by a thread. The paper roller 100, the fixing pin 210 and the shaft rod 220 are coaxially arranged when connected. One end of the shaft rod 220 connected with the fixing pin 210 is engaged with the end of the paper roller 100 by a slot. A second rolling bearing 230 is sleeved on the outer wall of the shaft rod 220. A nut 240 is sleeved on the end of the shaft rod 220 away from the paper roller 100 by a thread. The second rolling bearing 230 sleeved on the outer wall of the shaft rod 220 is pressed by two washers 430 and two pressure plates 420 and installed in the mounting hole 410 opened at one end of the workbench 400. Among them, the nut 240 cooperates with the shaft 220 to clamp and define the positions of the two ends of the second rolling bearing 230, and the fixed pin 210 is installed on the threaded hole at one end of the shaft 220 and locked with a socket wrench. Compared with the prior art, this embodiment removes the long shaft that passes through the paper roll 100 in the prior art for easy installation. In order to ensure that the paper roll 100 is coaxial with the fixed component 200 and the paper roll is not easy to shake, the fixed pin 210 is set on the shaft 220 during the design of this embodiment. Furthermore, since the long shaft is omitted, the circumference of the shaft 220 can be set into a closed pattern, thereby preventing the paper roll 100 from slipping out of the groove of the shaft 220 during installation.

[0045] The movable assembly 300 includes a sleeve 310, a fixed seat 320 coaxially connected to one end of the sleeve 310 by a thread, an insert rod 330 and two elastic members 350 symmetrically arranged in the fixed seat 320. The inner wall and outer wall of the sleeve 310 are respectively provided with a sliding bearing 360 and a first rolling bearing 370. The first rolling bearing 370 sleeved on the outer wall of the sleeve 310 is pressed and installed in the installation hole 410 opened at the other end of the workbench 400 by two washers 430 and two pressing plates 420. The outer wall of the insert rod 330 is provided with a sliding bearing 360 and a first rolling bearing 370. A pressing block 340 is provided on both sides of the wall, each pressing block 340 is provided with an arc-shaped pressing surface 341, and the pressing block 340 corresponds to the elastic member 350 one by one; the fixed seat 320 includes a base 324 connected to the shaft sleeve 310 by a thread and a pressure cover 325 detachably connected to the base 324 by two bolts 328, and the base 324 is recessed toward one side of the pressure cover 325 to form a rotation groove 321 for accommodating the two elastic members 350, and the rotation groove 321 is provided with a platform corresponding to the two elastic members 350 one by one The step surface 322 is used to press the end of the corresponding elastic member 350 close to the paper roll 100. The side of the pressure cover 325 facing the base 324 is provided with a positioning groove 323 corresponding to the two elastic members 350. The positioning groove 323 is used to accommodate the end of the corresponding elastic member 350 away from the paper roll 100. The base 324 is provided with a through hole 326 for the insertion rod 330 to pass through, and the pressure cover 325 is provided with a strip-shaped opening 327 for the insertion rod 330 and the pressing block 340 to pass through; one end of the insertion rod 330 is along the axis When it moves and rotates, the insertion rod 330 passes through the fixing seat 320 and the sleeve 310 and is clamped in the clamping hole 110 at one end of the paper roller 100, and drives the pressing surface 341 of each pressing block 340 to squeeze the corresponding elastic member 350 in the direction away from the paper roller 100, wherein the pressing surface 341 squeezes the corresponding elastic member 350 against one end of the corresponding step surface 322 when rotating; the elastic member 350 is a rectangular spring, so as to utilize its higher strength and elastic potential energy to increase the squeezing and locking force on the paper roller 100.

[0046] When the paper roll installation mechanism provided in this embodiment is used, first, the fixed component 200 and the movable component 300 are respectively installed in the installation holes 410 opened at both ends of the workbench 400. Specifically, the first rolling bearing 370 sleeved on the outer wall of the shaft sleeve 310 in the movable component 300 and the second rolling bearing 230 sleeved on the outer wall of the shaft rod 220 in the fixed component 200 are respectively pressed and installed in the installation holes 410 opened at both ends of the workbench 400 through two washers 430 and two pressing plates 420. Then, the paper roll 100 can be installed on the paper roll installation mechanism. Specifically, first, one end of the paper roll 100 is inserted into the shaft rod 220. 0, and the fixing pin 210 connected to the end of the shaft rod 220 of the fixing assembly 200 is inserted into and clamped into the clamping hole 110 at one end of the paper roll 100, so that the shaft rod 220 is coaxially connected and fixed with the paper roll 100 through the fixing pin 210, and the fixing of one end of the paper roll 100 is completed. Then, the other end of the paper roll 100 is lifted, and the clamping hole 110 at the other end of the paper roll 100 is aligned with the shaft sleeve 310 of the movable assembly 300 installed at the other end of the workbench 400, and the insertion rod 330 is moved axially, so that one end of the insertion rod 330 passes through the fixing seat 320 and the shaft sleeve 310 in sequence and is clamped to the paper roll 100. The clamping hole 110 at the other end, the cylinder at the end of the insertion rod 330 is clamped with the clamping hole 110 at the end of the paper winding roller 100, and the tapered part of the insertion rod 330 is pressed against the chamfer of the inner hole of the clamping hole 110 at the end of the paper winding roller 100, so as to ensure that the insertion rod 330 and the paper winding roller 100 are coaxially connected. At this time, the two pressing blocks 340 connected to the outer wall of the insertion rod 330 pass through the strip opening 327 provided on the pressure cover 325 and are inserted into the rotating groove 321 formed by the depression of the base 324, so that the pressing blocks 340 on both sides of the insertion rod 330 are located at the end of the two elastic members 350 away from the pressure cover 325, and the side of the pressing block 340 facing the paper winding roller 100 is in Between the two surfaces of the corresponding step surface 322, when the insertion rod 330 is rotated 60 degrees, the insertion rod 330 drives the two pressing blocks 340 to rotate, so that the pressing surfaces 341 of the two pressing blocks 340 rotate respectively and squeeze the two elastic members 350 to press against one end of the corresponding step surface 322, thereby utilizing the pressing surfaces 341 of the two pressing blocks 340 to squeeze and compress the two corresponding elastic members 350 in a direction away from the paper roller 100, thereby utilizing the elastic reaction force of the compressed elastic member 350 to reversely press the pressing block 340 and the insertion rod 330 to fix them to the paper roller 100, thereby completing the fixation of the other end of the paper roller 100.

[0047] When the paper roll needs to be replaced after use, it is only necessary to rotate the insertion rod 330 in the opposite direction so that the two pressing blocks 340 rotate to realign with the strip-shaped opening 327 set on the pressure cover 325. At this time, the pressing surfaces 341 of the two pressing blocks 340 stop rotating to press the elastic member 350, and the elastic member 350 elastically resets to press the step surface 322 set in the rotating groove 321. The insertion rod 330 is pulled out and disengaged from the clamping hole 110 at one end of the paper roll 100, so that the paper roll 100 can be separated from the movable component 300 and replaced with a new paper roll 100. Subsequently, the above steps can be repeated to reconnect the paper roll 100 with the fixed component 200 and the movable component 300 to complete the paper roll replacement operation.

[0048] Compared with the prior art, the paper roll installation mechanism provided in this embodiment has a greatly simplified structure, reduces the use of connecting fixings, and eliminates the long insertion rod in the prior art, thereby effectively reducing the weight of the overall device and avoiding the need to pass the long insertion rod through the paper roll roller 100 for connection and fixing, thereby simplifying the process of replacing the paper roll. The user only needs to rotate the insertion rod 330 forwards and reversely to use the pressing block 340 connected to the insertion rod 330 to press or stop pressing the elastic member 350 in the fixing seat 320, thereby using the compression force of the elastic member 350 to press and fix the insertion rod 330 to the paper roll roller 100 or release the fixation, thereby facilitating the user to quickly and efficiently load and unload the paper roll roller 100 for paper roll replacement.

[0049] The roll paper installation mechanism provided in this embodiment simplifies the structure, adopts the fixed pin 210 and the insertion rod 330 to replace the role of the long insertion rod, and reduces the total mass of the roll paper installation mechanism. Since four printing workbenches 400 are generally provided on a turntable 500, each workbench 400 fixes two roll paper rollers 100 through two roll paper installation mechanisms, so that the total weight of the eight groups of roll paper installation mechanisms provided on the turntable 500 is effectively reduced, which helps to reduce the overall inertia and increase the speed of the DD motor 510 to improve production capacity. At the same time, by rotating the insertion rod 330, the arc-shaped pressing surface 341 of the pressing block 340 of the insertion rod 330 gradually compresses the rectangular spring to achieve the purpose of pressing the roll paper roller 100 and maintaining the thrust, which can prevent the roll paper roller 100 from axial shaking. The fixing pin 210 and the insertion rod 330 are respectively inserted into the clamping holes 110 at both ends of the paper roll 100 for positioning, and the conical surface at the end of the insertion rod 330 is used to fit the chamfer of the clamping hole 110 of the paper roll 100 to prevent the paper roll 100 from radial shaking.

[0050] In other optional embodiments, the elastic member 350 may also use a rubber column. When the rectangular spring is replaced with an elastic material such as a rubber column, it is necessary to add a metal sheet between the rubber column and the insertion rod 330 to separate the insertion rod 330 from the rubber column to prevent the rubber column from wearing.

[0051] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.
