Description

Technical Field

[0001] This utility model belongs to the field of silicone rubber production technology, specifically relating to a multi-layer storage transfer rack. Background Technology

[0002] Silicone rubber tubing is widely used in modern industry due to its excellent high and low temperature resistance and its resistance to deliquescence and corrosion. During the production process, the silicone rubber tubing needs to be vulcanized in a vulcanizing furnace to cross-link and cure the silicone rubber. Some products require secondary vulcanization. During vulcanization, the silicone rubber tubing needs to be heated to 200℃ to give it elasticity and temperature resistance. At this high temperature, direct contact with the vulcanized tubing poses a safety hazard. Typically, the tubing is placed on multi-layered shelves to allow it to cool naturally. This method has low cooling efficiency and affects production efficiency.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a multi-layer storage transfer rack to improve the transfer efficiency of silicone rubber tubes, improve the cooling efficiency of silicone rubber tubes, and thus improve production efficiency.

[0005] Technical Solution: To achieve the above objectives, this utility model provides a multi-layer storage transfer rack, including a base plate, with uprights connected to the four corners of the top surface of the base plate, and a top plate connected to the top surface of each upright. A drawer-shaped tray is provided between the base plate and the top plate, and the tray is connected to the uprights via slide rails, arranged in an array from top to bottom along the uprights. Through holes are provided on the bottom surface of the tray, arranged in a grid pattern. Rollers are connected to the bottom surface of the base plate. This utility model places silicone rubber tubes in the drawer-shaped trays and transfers them to a heating furnace for heating and vulcanization. After vulcanization, the multi-layer storage transfer rack is rotated out, allowing the silicone rubber tubes to cool naturally. This utility model uses multiple trays to improve transfer efficiency, and the through holes at the bottom of the trays allow airflow to form an airflow path, increasing air convection and improving cooling efficiency.

[0006] Furthermore, in the aforementioned multi-layer storage transfer rack, a cooling device is connected to the top surface of the base plate, which blows cooling air towards the upward-facing pallet. The cooling device increases airflow velocity, creating a low-pressure zone at the bottom of the pallet, attracting surrounding air through the through-holes, thus improving the heat exchange efficiency between the air and the surface of the silicone rubber tube, reducing heat accumulation, and enhancing heat dissipation efficiency.

[0007] Furthermore, in the aforementioned multi-layer warehouse transfer rack, the air-cooling device is a cooling fan, electrically connected to a power module that provides power to the air-cooling device. The power module is designed to be detachable to prevent overheating and potential safety hazards. This power module configuration allows the air-cooling device to operate even without external power, enabling it to function during transfer, reducing cooling time, improving production efficiency, and enhancing the flexibility of the multi-layer warehouse transfer rack.

[0008] Furthermore, in the aforementioned multi-layer storage transfer rack, the slide rail includes a fixed rail, an intermediate rail, and a sliding rail. The fixed rail is connected to uprights at both ends, and the sliding rail is connected to the pallet. The fixed rail and the intermediate rail are slidably connected via a first ball bearing assembly, and the intermediate rail and the sliding rail are slidably connected via a second ball bearing assembly. One end of the fixed rail has a folded edge that folds towards the sliding rail, and the intermediate rail has a buffer section near the folded edge, made of a flexible material. The first and second ball bearing assemblies are each composed of a set of steel balls connected by a ball bearing frame. Using a fixed rail, intermediate rail, and sliding rail increases the pallet opening size and improves operational convenience. The buffer section reduces the impact force when the sliding rail moves to the end of the intermediate rail and when the intermediate rail moves to the end of the fixed rail, reducing noise, protecting the slide rail, and extending its service life.

[0009] Furthermore, in the aforementioned multi-layer storage transfer rack, a locking element is provided between the intermediate rail and the sliding rail. The locking element is located near the folded edge and aligns and locks the intermediate rail and the sliding rail. The locking element includes a baffle rotatably connected to the intermediate rail and a locking plate rotatably connected to the sliding rail. The locking plate has a hook portion, which engages with the baffle to lock the intermediate rail and the sliding rail. A locking handle is rotatably connected to the end of the sliding rail away from the folded edge. The locking handle is driven by a connecting rod and the locking plate. The locking handle drives the locking plate to deflect via the connecting rod. When the sliding rail moves to the end of the intermediate rail, the hook portion and the baffle engage to lock the intermediate rail and the sliding rail, preventing the pallet from sliding out during transfer and preventing items from falling and causing damage. When it is necessary to open the drawer, the locking handle is turned, and the locking handle drives the locking plate to deflect via the connecting rod, disengaging the hook portion and the baffle, allowing the pallet to be pulled out.

[0010] Furthermore, in the aforementioned multi-layer storage transfer rack, the baffle is provided with a pin hole, through which a pin shaft passes. A torsion spring is sleeved on the pin shaft, with its two ends connected to the baffle and the intermediate rail, respectively. The torsion spring provides torsional force to the baffle. The baffle is provided with a limiting flange, and the intermediate rail is provided with a limiting groove, which is provided with a limiting boss. The limiting flange and the limiting boss in the limiting groove abut against each other. When the sliding rail moves to the end of the intermediate rail, the hook presses against the baffle, causing the baffle to deflect around the pin hole. The torsion spring twists, the hook and the baffle engage, and the torsion spring pushes the baffle back to its original position.

[0011] Furthermore, in the aforementioned multi-layer storage transfer rack, a locking flange is provided on the side of the locking handle near the flange, and the locking flange is located on the upper side of the locking handle, inclined away from the flange. A fixed flange is provided on the end of the fixed rail near the locking handle, with the fixed flange having an arc shape on the side near the locking handle and a right angle on the side near the flange. The fixed flange is stamped from the fixed rail towards the sliding rail. The locking flange and the fixed flange abut against each other to lock the fixed rail and the sliding rail. When the sliding rail moves to the end of the fixed rail, the fixed flange pushes the locking flange, causing the locking flange to deflect and move along the upper surface of the fixed flange. When the right angle sides of the locking flange and the fixed flange abut against each other, the sliding rail and the fixed rail are locked. When it is necessary to remove the pallet, the locking handle is turned, the locking flange and the fixed flange disengage, and the pallet can be removed.

[0012] Furthermore, in the aforementioned multi-layered storage transfer rack, to improve the convenience of transfer, the pulleys are equipped with omnidirectional rollers. Handles are connected to the sides of the uprights.

[0013] Furthermore, in the aforementioned multi-layer storage transfer rack, a latch is connected to the top surface of the top plate, and the latch is set along the side of the top plate. A latching platform is connected to the side of the top plate away from the latch. When two or more multi-layer storage transfer racks need to be transferred, the multi-layer storage transfer racks are placed side by side, with the side with the latch abutting against the side of another transfer rack with the latching platform. The latch is then engaged with the latching platform, connecting the two or more multi-layer storage transfer racks. This facilitates the simultaneous transfer of multiple multi-layer storage transfer racks and improves work efficiency.

[0014] Furthermore, in the aforementioned multi-layer storage transfer rack, the uprights are equipped with magnetic strips on the side near the mounting platform. These magnetic strips can magnetically attract adjacent multi-layer storage transfer racks, magnetically positioning them for easy locking and securing to the mounting platform, thus improving operational convenience. Simultaneously, the magnetic strips can cushion collisions between the multi-layer storage transfer racks, reducing impact and noise.

[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects: The multi-layer storage transfer rack of this utility model is equipped with multiple pallets, improving transfer efficiency. Through holes are opened at the bottom of the pallets, allowing airflow to form an airflow path, increasing air convection and improving cooling efficiency. An air-cooling device is installed to increase airflow velocity, creating a low-pressure zone at the bottom of the pallet, attracting surrounding air to enter through the through holes, improving the heat exchange efficiency between the air and the surface of the silicone rubber tubes, reducing heat accumulation, and improving heat dissipation efficiency. The locking mechanism connects two or more multi-layer storage transfer racks, facilitating the simultaneous transfer of multiple multi-layer storage transfer racks and improving work efficiency.

Detailed Implementation

[0025] Example 1

[0026] like Figure 1 The multi-layer storage transfer rack shown includes a base plate 1, with uprights 2 connected to the four corners of the top surface of the base plate 1. A top plate 3 is connected to the top surface of each upright. Drawer-shaped trays 4 are provided between the base plate 1 and the top plate 3. The trays 4 are connected to the uprights 2 via slide rails 5, and are arranged in an array from top to bottom along the uprights 2. The bottom surface of each tray 4 has through holes 41 arranged in a grid pattern. Casters 7 are connected to the bottom surface of the base plate 1. The casters 7 are omnidirectional casters. Handles 8 are connected to the sides of the uprights 2.

[0027] In this embodiment, a cooling device 6 is connected to the top surface of the base plate 1, and the cooling device 6 blows cooling air towards the upper tray 4. The cooling device 6 is a cooling fan, and a power module is electrically connected to the cooling device 6, which provides power to the cooling device 6. The power module is designed to be detachable, and overheating of the power module should be avoided to prevent safety accidents.

[0028] like Figure 2-4The multi-layer storage transfer rack shown includes a slide rail 5 comprising a fixed rail 51, an intermediate rail 52, and a sliding rail 53. The fixed rail 51 is connected to the uprights 2 at both ends, and the sliding rail 53 is connected to the pallet 4. The fixed rail 51 and the intermediate rail 52 are slidably connected via a first ball bearing assembly 54, and the intermediate rail 52 and the sliding rail 53 are slidably connected via a second ball bearing assembly 55. One end of the fixed rail 51 has a folded edge 511 that folds towards the sliding rail 53. The intermediate rail 52 has a buffer portion 531 near the folded edge 511, and the buffer portion 531 is made of a flexible material. The first ball bearing assembly 54 and the second ball bearing assembly 55 are each a set of steel balls connected by a ball bearing frame.

[0029] In this embodiment, a locking member is provided between the intermediate rail 52 and the sliding rail 53. The locking member is located near the folded edge 511 and aligns and locks the intermediate rail 52 and the sliding rail 53. The locking member includes a baffle 551 rotatably connected to the intermediate rail 52 and a locking piece 552 rotatably connected to the sliding rail 53. The locking piece 552 has a hook portion 5521, which engages with the baffle 551 to lock the intermediate rail 52 and the sliding rail 53. A locking handle 553 is rotatably connected to the end of the sliding rail 53 away from the folded edge 511. The locking handle 553 is driven to connect to the locking piece 552 via a connecting rod 554. The locking handle 553 drives the locking piece 552 to deflect via the connecting rod 554.

[0030] like Figure 5 The multi-layer storage transfer rack shown has a baffle 551 with a pin hole 5511. A pin is inserted into the pin hole 5511, and a torsion spring 555 is sleeved on the pin. The two ends of the torsion spring 555 are connected to the baffle 551 and the intermediate rail 52, respectively. The torsion spring 555 provides torsional force to the baffle 551. The baffle 551 has a limiting flange 5512, and the intermediate rail 52 has a limiting groove 521 with a limiting boss. The limiting flange 5512 and the limiting boss in the limiting groove 521 abut against each other.

[0031] like Figure 6-7 The multi-layer storage transfer rack shown has a locking flange 5531 on the side of the locking handle 553 near the flange 511. The locking flange 5531 is located on the upper side of the locking handle 553 and is inclined away from the flange 511. A fixing flange 512 is provided on the end of the fixed rail 51 near the locking handle 553. The fixing flange 512 is arc-shaped on the side near the locking handle 553 and right-angled on the side near the flange 511. The fixing flange 512 is stamped from the fixed rail 51 towards the sliding rail 53. The locking flange 5531 and the fixing flange 512 abut against each other to lock the fixed rail 51 and the sliding rail 53.

[0032] This utility model involves turning the locking handle 553, causing the locking flange 5531 to rotate, disengaging the locking flange 5531 from the fixing flange 512. This causes the connecting rod 554 to drive the locking piece 552 to deflect, disengaging the hook 5521 from the stop piece 551, and pulling out the tray 4. The silicone rubber tube is then placed inside the drawer-shaped tray 4. When the tray 4 is closed, the sliding rail 53 moves to the end of the intermediate rail 52. The hook 5521 presses against the stop piece 551, causing the stop piece 551 to deflect around the pin hole 5511. This causes the torsion spring 555 to twist, engaging the hook 5521 and the stop piece 551. The torsion spring 555 pushes the stop piece 551 back to its original position, and the engagement of the hook 5521 and the stop piece 551 locks the intermediate rail 52 and the sliding rail 53. The fixed folding edge 512 pushes the locking folding edge 5531, which rotates and moves along the upper surface of the fixed folding edge 512. When the locking folding edge 5531 and the fixed folding edge 512 abut at their right angles, the sliding rail 53 and the fixed rail 51 lock together. The multi-layer storage transfer rack is then transferred into the heating furnace. The power module is removed, and heating and vulcanization are performed. After vulcanization, the multi-layer storage transfer rack is rotated out, the power module is installed, and the air-cooling device 6 is activated. The air-cooling device 6 blows cooling air towards the upper tray 4 to accelerate air convection and improve the cooling speed of the silicone rubber tube.

[0034] The difference between this embodiment and Embodiment 1 is that, as Figure 1 The multi-layer storage transfer rack shown has a locking buckle 91 connected to the top surface of the top plate 3, with the buckle 91 arranged along the side of the top plate 3. A fastening platform 92 is connected to the side of the top plate 3 away from the locking buckle 91. A magnetic adhesive strip 93 is provided on the side of the upright 2 near the fastening platform 92.

[0035] When two or more multi-level storage transfer racks need to be transferred, the multi-level storage transfer racks are placed side by side, with the side with the locking buckle 91 abutting against the side with the buckle platform 92 of another transfer rack. The magnetic strip 93 magnetically attracts the adjacent multi-level storage transfer racks, magnetically positioning the adjacent multi-level storage transfer racks. The locking buckle 91 is then fastened to the buckle platform 92, connecting two or more multi-level storage transfer racks. This facilitates the simultaneous transfer of multiple multi-level storage transfer racks and improves work efficiency.
