Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet manufacturing equipment technology, and in particular to a sheet hanging rod drying machine. Background Technology
[0002] Tofu sheets are long, sheet-like, and resilient bean products formed by pressing tofu. During the production process, freshly made tofu sheets are at a high temperature and are not firmly formed, which is not conducive to later packaging and transportation. Therefore, tofu sheets need to be cooled and reshaped to ensure their integrity and a smooth surface.
[0003] Existing air-cooled tofu sheets production lines use a mesh belt structure to transport the tofu sheets. During the transport process, a fan blows air through the gaps in the mesh belt, carrying away the heat from the tofu sheets. However, the above-mentioned transport structure is relatively complex, occupies a large space, and the mesh belt is not easy to clean.
[0004] Therefore, there is an urgent need for a simple, easy-to-clean, and stable sheet drying machine. Utility Model Content
[0005] The purpose of this utility model is to provide a thousand-sheet hanging rod drying machine that solves the technical problems of complex structure, large footprint, and difficulty in cleaning the mesh belt in existing technologies. The various technical effects of the preferred technical solutions provided by this utility model are detailed below.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] This utility model provides a thousand-sheet hanging rod drying machine, including a frame, several sprockets rotatably connected to the frame, a first motor driving the sprockets, and a fan mounted on the frame, and further including:
[0008] The lower chain and the upper chain are arranged symmetrically, with two sets of lower chains wound around several sprockets. The unloaded return rods on the two sets of upper chains are corresponding to the output end of the tofu production equipment. The unloaded return rods are transferred to the upper chains via the lower chains, and the return rods carrying tofu are transferred to the lower chains via the upper chains. The running speed of the upper chains is greater than that of the lower chains, and the distance between adjacent return rods on the upper chains is greater than the distance between adjacent return rods on the lower chains.
[0009] Preferred options also include:
[0010] Chain lugs, with the bottom ends of several chain lugs fixedly connected at equal intervals to the lower chain and the upper chain, the return rod being located on one side of the chain lugs in the direction of travel, and the distance between adjacent chain lugs on the upper chain being greater than the distance between adjacent chain lugs on the lower chain.
[0011] Preferred options also include:
[0012] The first support rod track is mounted on the frame and located below the lower chain. The top end of the chain lug on the lower chain is slidably connected to the first support rod track. The inlet and outlet ends of the first support rod track are respectively set as arc-shaped structures.
[0013] Preferred options also include:
[0014] The second support rod track is installed on the frame, and the second support rod track is installed at an angle on the frame. The lower end of the second support rod track corresponds to the leather sorting platform, and the upper end of the second support rod track is lower than the transfer plane of the tofu sheets on the lower chain. The return rod, which is empty after passing through the leather sorting platform, is manually placed onto the lower chain.
[0015] Preferred options also include:
[0016] A palletizing unit is installed on the frame and located between the leather handling platform and the lower chain. The unloaded return rods passing through the leather handling platform are manually placed into the palletizing unit, and the unloaded return rods are transferred to the lower chain through the palletizing unit.
[0017] Preferably, the palletizing unit includes:
[0018] A storage box, which is mounted on the frame;
[0019] The pulleys and belts are respectively rotatably connected to the frame and driven by a second motor on the frame. Two sets of belts are respectively wound around the pulleys and located below the outlet at the bottom of the storage box.
[0020] The third support rail is installed between the bottom of the storage box and the lower chain.
[0021] Preferably, the surface of the belt has protrusions fixedly connected at equal intervals along the conveying direction, and the height of the protrusions is the same as the cross-sectional size of the return rod.
[0022] Preferred options also include:
[0023] The fourth support rail is installed at an angle on the frame and is positioned from high to low between the sheet transfer plane on the upper chain and the lower chain.
[0024] In the technical solution provided by this utility model, a lower chain and an upper chain are used, with return rods placed on the lower and upper chains. The unloaded return rod is transferred to the upper chain via the lower chain. The front end of the tofu sheets at the discharge end of the tofu sheet production equipment falls first. When half of the tofu sheet has fallen, the upper chain drives the unloaded return rod forward, causing the other half of the tofu sheet to fall behind the hanging rod. At this point, the tofu sheet is suspended on the hanging rod, i.e., the hanging rod is located in the middle of the tofu sheet. Then, the return rod carrying the tofu sheet is transferred to the lower chain via the upper chain. Because the distance between adjacent return rods on the upper chain is greater than the distance between adjacent return rods on the lower chain, more return rods can be placed on the lower chain, meaning more tofu sheets can be suspended. This allows for the cooling of more tofu sheets within the same time and space. This invention effectively improves the heat dissipation efficiency of dried tofu sheets. Because the return rods on the upper chain suspend dried tofu sheets, their weight presses down on the rods, ensuring stability during operation. However, if the upper chain's speed equals the lower chain's speed, the unloaded return rods on the lower chain are prone to displacement, affecting the smoothness of the lower chain's operation and potentially causing it to jam. Therefore, by setting the upper chain's speed greater than the lower chain's speed, the lower chain and its unloaded return rods can move stably during operation. After the dried tofu sheets on the lower chain are manually removed, the unloaded return rods are transferred back to the upper chain via the lower chain, where new sheets are then suspended, and this cycle repeats. During this transfer process, the return rods facilitate the suspension of dried tofu sheets and cleaning. Overall, this application features a simple structure, small footprint, and ensures stable operation while improving heat dissipation efficiency. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0034] refer to Figure 1-6 A specific embodiment of this utility model provides a thousand-sheet hanging rod drying machine, including a frame 1, several sprockets rotatably connected to the frame 1, a first motor driving the sprockets, and a fan 14 mounted on the frame 1, and further including:
[0035] The lower chain 3 and the upper chain 4 are respectively wound around several sprockets and arranged symmetrically. The two sets of upper chains 4 are respectively wound around several sprockets and arranged symmetrically. The unloaded return rods 6 on the two sets of upper chains 4 are corresponding to the output end of the tofu production equipment. The unloaded return rods 6 are transferred to the upper chains 4 through the lower chains 3, and the return rods 6 carrying tofu are transferred to the lower chains 3 through the upper chains 4. The running speed of the upper chains 4 is greater than the running speed of the lower chains 3, and the distance between adjacent return rods 6 on the upper chains 4 is greater than the distance between adjacent return rods 6 on the lower chains 3.
[0036] Existing air-cooled tofu sheets production lines use a mesh belt structure to transport the tofu sheets. During the transport process, a fan blows air through the gaps in the mesh belt, carrying away the heat from the tofu sheets. However, the above-mentioned transport structure is relatively complex, occupies a large space, and the mesh belt is not easy to clean. In this application, a lower chain 3 and an upper chain 4 are used, with the return rod 6 placed on the lower chain 3 and the upper chain 4. The unloaded return rod 6 is transferred to the upper chain 4 via the lower chain 3. The front end of the tofu sheet at the discharge end of the tofu sheet production equipment falls first. When half of the tofu sheet has fallen, the upper chain 4 moves the unloaded return rod 6 forward, causing the other half of the tofu sheet to fall behind the return rod 6. At this point, the tofu sheet is suspended on the return rod 6, i.e., the return rod 6 is located in the middle of the tofu sheet. Then, the return rod 6 carrying the tofu sheet is transferred to the lower chain 3 via the upper chain 4. Because the distance between adjacent return rods 6 on the upper chain 4 is greater than the distance between adjacent return rods 6 on the lower chain 3, more return rods 6 can be placed on the lower chain 3, meaning more tofu sheets can be suspended. This allows for the cooling of more tofu sheets within the same time and space, effectively improving efficiency. The heat dissipation efficiency of the tofu sheets is improved because the tofu sheets are suspended on the return rods 6 of the upper chain 4. The weight of the tofu sheets presses on the return rods 6, ensuring their stability during operation. However, if the operating speed of the upper chain 4 is equal to that of the lower chain 3, the unloaded return rods 6 on the lower chain 3 are prone to displacement, affecting the smooth operation of the lower chain 3 and potentially causing it to jam. Therefore, by setting the operating speed of the upper chain 4 to be greater than that of the lower chain 3, the lower chain 3 and its unloaded return rods 6 can move stably during operation. After the tofu sheets on the lower chain 3 are manually removed, the unloaded return rods 6 are transferred back to the upper chain 4 via the lower chain 3, where new tofu sheets are suspended, and this cycle repeats. During the transfer process, the return rods 6 facilitate the suspension of tofu sheets and are easy to clean. Overall, this application has a simple structure, occupies little space, and improves heat dissipation efficiency while ensuring stable operation.
[0037] The first motor (not shown in the figure) is mounted on the frame 1. The sprockets connecting the lower chain 3 and the upper chain 4 are respectively connected to the output shaft of the first motor. This can be a conventional chain drive or gear drive (not shown in the figure). The running speed of the upper chain 4 is higher than that of the lower chain 3. For example, when the upper chain 4 moves 10-20 pitches, the lower chain 3 moves 1 pitch. When the upper chain 4 moves forward at a linear speed of 45 meters per second, the lower chain 3 moves forward at a linear speed of 4.5 meters per second.
[0038] Further optimizations to the plan include:
[0039] Chain lugs 5, the bottom ends of several chain lugs 5 are fixedly connected at equal intervals to the lower chain 3 and the upper chain 4, the return rod 6 is located on one side of the traveling direction of the chain lugs 5, and the distance between adjacent chain lugs 5 on the upper chain 4 is greater than the distance between adjacent chain lugs 5 on the lower chain 3.
[0040] The main function of the chain lug 5 is to push the return lever 6 on the lower chain 3 and the upper chain 4, ensuring that the return lever 6 moves synchronously with the lower chain 3 and the upper chain 4 during the transfer process.
[0041] Further optimizations to the plan include:
[0042] The first support rail 2 is installed on the frame 1 and located below the lower chain 3. The top of the chain lug 5 on the lower chain 3 is slidably connected to the first support rail 2. The inlet and outlet of the first support rail 2 are respectively set as arc-shaped structures.
[0043] When the lower chain 3 is transferring the return rod 6 carrying thousand sheets, the top of the chain ear plate 5 faces upwards, making it easy to manually remove the thousand sheets. When the lower chain 3 is transferring the empty return rod 6, in order to ensure that the lower chain 3 can continuously drive the empty return rod 6 to move (return) to the upper chain 4, the chain ear plate 5 needs to push the return rod 6 into the first support rod track 2. Inside the first support rod track 2, the top of the chain ear plate 5 faces downwards. At this time, the top of the chain ear plate 5 is slidably connected to the inner wall of the first support rod track 2, and the end of the empty return rod 6 rests on the inner wall of the first support rod track 2. The chain ear plate 5 can continue to drive the empty return rod 6 to move, that is, push the empty return rod 6 to slide on the inner wall of the first support rod track 2. In order to ensure that the empty return rod 6 can smoothly enter or move out of the first support rod track 2, the inlet and outlet ends of the first support rod track 2 are respectively set as arc-shaped structures. Figure 3 As shown, the chain lug 5 is in a vertical position before entering the arc-shaped structure, set to 0°, as... Figure 2 As shown, after the chain lug 5 moves out of the arc structure (i.e., after passing the upper sprocket), it is 360° and remains at 360° until the unloaded return rod 6 is transferred to the traveling side of the chain lug 5 on the upper chain 4, and the next step is to receive the tortoise shell.
[0044] Further optimizations to the plan include:
[0045] The second support rail 8 and the leather sorting platform 9 are installed on the frame 1. The second support rail 8 is installed at an angle on the frame 1. The lower end of the second support rail 8 corresponds to the leather sorting platform 9. The upper end of the second support rail 8 is lower than the transfer plane of the tofu sheets on the lower chain 3. The empty return rod 6 passing through the leather sorting platform 9 is manually placed onto the lower chain 3.
[0046] The return lever 6, carrying thousands of sheets, gradually approaches the second support rail 8 and falls to the high end of the second support rail 8. Then it slides from high to low and approaches the leather sorting platform 9. The operator picks up the return lever 6 carrying thousands of sheets and removes the thousands of sheets. Then the empty return lever 6 is placed on the lower chain 3, and the lower chain 3 continues the process of transferring the empty return lever 6 to the upper chain 4.
[0047] Further optimizations to the plan include:
[0048] The palletizing unit is installed on the frame 1 and is located between the leather handling platform 9 and the lower chain 3. The empty return bar 6 passing through the leather handling platform 9 is manually placed into the palletizing unit, and the empty return bar 6 is transferred to the lower chain 3 through the palletizing unit.
[0049] Before being placed onto the lower chain 3, the return rod 6, which has been removed from the first thousand sheets, is placed in the palletizing unit by the operator. The palletizing unit automatically stacks the empty return rods 6 and places them onto the lower chain 3 in an orderly manner, reducing the labor intensity of the operators and improving production efficiency.
[0050] The solution has been further optimized, and the palletizing unit includes:
[0051] Storage box 10, which is installed on the rack 1;
[0052] The pulleys and belts 11 are rotatably connected to the frame 1 and driven by the second motor 12 on the frame 1. The two sets of belts 11 are wound around the pulleys and are symmetrically arranged below the outlet at the bottom of the storage box 10.
[0053] The third support rail 13 is installed between the bottom of the storage box 10 and the lower chain 3.
[0054] In a further optimized design, protrusions are fixedly connected at equal intervals along the conveying direction on the surface of belt 11, and the height of the protrusions is the same as the cross-sectional dimensions of return rod 6.
[0055] The space within the third support rail 13 is designed to accommodate only a single row of return rods 6. The empty return rods 6 placed in the storage box 10 are placed on two sets of belts 11. The protrusions push the return rods 6 into the third support rail 13 in sequence, and they are stacked in a single row within the third support rail 13 according to gravity. Every time the lower chain 3 at the bottom of the third support rail 13 moves by 1 pitch, the empty return rod 6 at the bottom falls between the adjacent chain ear plates 5, thus automatically placing a set of empty return rods 6 between adjacent chain ear plates 5. Then, the empty return rods 6 enter the arc-shaped structure of the first support rail 2 along with the chain ear plates 5.
[0056] Further optimizations to the plan include:
[0057] The fourth support rail 15 is installed on the frame 1 and is set at an angle. The fourth support rail 15 is set from high to low between the thousand sheet transfer plane on the upper chain 4 and the lower chain 3.
[0058] The main function of the fourth support rail 15 is to provide a slide rail for the return rod 6 carrying the thousand sheets, so that the return rod 6 on the upper chain 4 can fall smoothly onto the lower chain 3, ensuring the smoothness of the transfer process.
