[0002] Existing heavy-duty leather printing rollers on the market are large and heavy, requiring sophisticated handling equipment and space layout. Current storage areas have limited capacity, and retrieving rollers is inconvenient and difficult, requiring workers to use forklifts and other lifting devices. This process is time-consuming, labor-intensive, and dangerous for workers.

[0003] Therefore, it is particularly important to design a heavy-duty rubber roller warehouse with a large cargo space, convenient storage and retrieval, and easy access to the rubber rollers. Utility Model Content

[0004] This application provides a heavy-duty rubber roller magazine, which adopts the following technical solution:

[0005] A heavy-duty rubber roller storage unit includes a base, a support column on the base, and several crossbeams on the support column. A motor is mounted on the top of the storage unit, and a drive rod is mounted on the motor. Drive sprockets are mounted on both sides of the drive rod, and the drive sprockets drive driven sprockets to rotate via drive chains. Upper and lower sprockets are arranged on both sides of the storage unit, and roller chains are mounted on the upper and lower sprockets. Pin fittings are mounted on the sides of the roller chains, and hanging shafts are mounted on the pin fittings. Rubber rollers are mounted on hooks on the hanging shafts, and bearings are mounted on the hooks to hang the weight of the rubber rollers.

[0006] Optionally, rubber roller shafts are provided on both sides of the rubber roller, and the rubber roller shafts are set inside the hooks.

[0027] An embodiment of this utility model provides a heavy-duty rubber roller magazine.

[0028] Example: Figure 1-7As shown, a heavy-duty rubber roller storage unit includes a base 1, on which a support column 101 is mounted. Several crossbeams 102 are mounted on the support column 101. The support column 101 and the crossbeams 102 are interconnected to form an integral rubber roller storage unit frame. A motor 2 is mounted on the top of the storage unit. A drive rod 201 is mounted on the motor 2, and several fixing blocks 202 are mounted on the drive rod 201. Bearings are mounted on the fixing blocks 202 and connected to the drive rod 201. Drive sprockets 203 are mounted on both sides of the drive rod 201. Drive chains 204 are mounted on the drive sprockets 203, and driven sprockets 205 are mounted on the drive chains 204. The rotation of the drive sprockets 203 drives the drive chains 204, which in turn drives the driven sprockets 205 to rotate.

[0029] An upper sprocket 7 and a lower sprocket 8 are installed inside the roller magazine. The upper sprocket 7 and the lower sprocket 8 are fixedly installed on the crossbeam. The upper sprocket 7 and the lower sprocket 8 are arranged on opposite sides. A driven sprocket 205 is installed on the upper sprocket 7. When the driven sprocket 205 rotates, the upper sprocket 7 also rotates. A roller chain 4 is installed on the upper sprocket 7 and the lower sprocket 8. The roller chain 4 is installed on both sides of the upper sprocket 7 and the lower sprocket 8. A pin fitting is installed on the side of the roller chain 4. A mounting shaft 301 is installed on the pin fitting. The mounting shaft 301 is fixedly connected to the pin fittings of the roller chain 4 on both sides. A hook 302 is installed on the mounting shaft 301. A bearing is installed on the hook 302. The hook 302 and the mounting shaft 301 are connected through the bearing. At the same time, the bearing allows the hook 302 to rotate on the mounting shaft 301. A rubber roller 3 is mounted on the hook 302, and rubber roller shafts 303 are mounted on both sides of the rubber roller 3. The rubber roller shafts 303 are located inside the hook 302 to achieve the hoisting of the rubber roller 3.

[0030] A tensioning device is installed inside the roller magazine to adjust the tension of the entire roller chain 4, ensuring its stability. A fixed rod 103 is installed on the roller magazine, and an adjusting block 601 is installed on the fixed rod 103. A tensioning wheel 6 is installed on the adjusting block 601, and the axle 602 of the tensioning wheel 6 is installed inside the adjusting block 601. At the same time, an adjusting device 5 is also installed on the fixed rod 103, and a frame is installed on the adjusting device 5. The frame is installed on the fixed rod 103 to fix the entire adjusting device 5. The adjusting device 5 is located on both sides of the fixed rod 103. A handwheel 501 is installed on the adjusting device 5, and a lifting adjustment mechanism 502 is installed inside the adjusting device 5. A connecting rod 503 is installed on the lifting adjustment mechanism 502. Turning the handwheel 501 can control the up and down movement of the lifting adjustment mechanism 502, and the up and down movement of the lifting adjustment mechanism 502 can realize the movement of the connecting rod 503.

[0031] A slider is installed inside the adjusting block 601, and a tensioning wheel 6 is installed on the slider. The axle 602 of the tensioning wheel 6 is mounted on the slider. The slider can move within the adjusting block 601 and is locked to the adjusting block 601 with a locking nut. The tensioning wheel 6 rotates through the engagement of the axle 602 and a bearing. In use, the handwheel 501 can be rotated to move the lifting adjustment mechanism 502 up and down. The handwheel 501 and the lifting adjustment mechanism 502 are connected by a lead screw. As the lifting adjustment mechanisms 502 on both sides move, the connecting rod 503 in the middle moves accordingly, causing the tensioning wheel 6 to change position, thereby adjusting the tension of the roller chain 4. Then, the adjusting block and slider on the tensioning device are adjusted to change the tension of the roller chain 4 and ensure stability.

[0032] The base 1 is a 300mm thick cast base with eight adjustable feet. A 6-axis digital level is installed on the roller magazine to monitor the equipment's tilt and prevent accidents caused by tilting. Currently, similar rollers on the market generally weigh less than 200kg each, with a total load capacity of less than 10 tons. This device designs the roller 3 to be 2910mm long and 340mm in diameter, with a single roller weighing 500kg. A full load of 65 rollers results in a combined load capacity exceeding 30 tons. Furthermore, roller 3 is designed for heavy-duty leather printing.

[0033] The roller storage unit adopts a four-section distribution design to avoid concentrating weight in one area and instead distribute the weight. The first section consists of the upper sprocket 7 and the lower sprocket 8 below it, which can hold a maximum of 22 products with a load of 11 tons. The second section consists of the upper sprockets 7 on both sides, which can hold a maximum of 7 products with a load of 3.5 tons. The third section is between the two rotating sprockets 12, which can hold a maximum of 34 materials with a load of 17 tons. The fourth section is the tensioning device, which can hold a maximum of 3 materials with a load of 1.5 tons. All chains are equipped with limit strips to ensure that the sprockets do not wobble.

[0034] To facilitate loading and unloading by workers, a wheel engaging groove 11 is provided on the side of the base 1. The wheel engaging groove 11 can engage the wheel of the trolley 9. A rubber roller limiting groove 10 is provided on the trolley 9. The rubber roller shaft 303 on the rubber roller 3 is placed in the rubber roller limiting groove 10, which makes it convenient for workers to transport materials by trolley.

[0035] Working principle: This device is intelligently controlled by a PLC, a machine-side station, and a server. Through intelligent control, it can link the production line order status and pre-position the rubber rollers required for the current shift at the feeding position. In feeding mode, the equipment is switched to feeding mode, and the code of the rubber roller 3 is read and identified. The equipment intelligently allocates empty hooks 302 according to the counterweight, pushes the trolley 9 into the wheel locking groove 11, and centers the trolley. A sensor and electromagnet are set in the wheel locking groove 11. After the sensor detects that the trolley 9 is in place, it sends a signal back, and the equipment starts the electromagnet to automatically fix the trolley 9 in the fixed position. After the worker confirms the position of the hook 302, he presses the start button. The roller chain 4 rotates and rises, driving the hanging shaft 301 to rise. The hook 302 engages with the rubber roller shaft 303 on the rubber roller 3 and lifts the rubber roller 3. At this time, the equipment reminds the operator to take over the trolley 9 with sound and light. After the electromagnet releases the trolley 9, the worker moves the empty trolley 9 out, completing one feeding action. After the material is unloaded, the equipment will transport the rubber roller 3 to the designed position according to the counterweight to balance the weight on the roller chain 4.

[0036] When the production line needs rubber rollers, simply specify the model of rubber roller 3 on the remote page. The equipment will pre-configure the required rubber roller 3 to the unloading position. When the empty trolley 9 enters the wheel clamping slot 11 of the equipment and is detected by the sensor, the electromagnet locks the trolley 9. After manual confirmation, press the start button, and the equipment will automatically drop the target rubber roller onto the trolley 9 and remind the operator to take over the trolley 9 with sound and light. After the trolley leaves the equipment, the equipment enters the state of waiting for the next inbound / outbound command.

[0037] This device uses motor 2 to drive drive rod 201 to achieve bilateral drive, providing rotational power to upper sprocket 7. The interaction between upper sprocket 7 and lower sprocket 8 synchronizes the roller chains 4 on both sides. The roller chains are custom-made 32A roller chains with pin-mounting fixtures for mounting. The custom-made 32A roller chains have sufficient strength to mount the rubber rollers. Bearings are used on the mounting shaft 301 to achieve the self-weight hanging function of hook 302. This device can achieve forward and reverse transport and mounting without requiring clearance holes on the sprockets, thus maintaining strength. A housing is installed on the rubber roller storage unit to protect the entire unit.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and not restrictive in all respects. The scope of this invention is defined by the appended claims, not by the foregoing description, and is therefore intended to encompass all variations falling within the meaning and scope of equivalents of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
