Description

Technical Field

[0001] This application belongs to the field of food processing equipment technology, and more specifically, relates to a material hoist. Background Technology

[0002] A material hoist is a specialized piece of equipment that transports and elevates food materials by changing their potential energy. In the production of fried foods, freshly fried food is typically transported to the packaging process via a material hoist for final packaging and shipment. Since freshly fried food is at a high temperature, food processing companies usually use conveyor belts made of mesh metal for lifting and transporting it. However, in the current process of producing and packaging fried foods, when using material hoists to lift and transport fried foods via mesh conveyor belts, there is a tendency for food debris to increasingly adhere to the surface of the mesh conveyor belt.

[0003] To address the aforementioned issues, Chinese Patent No. CN220181808 U discloses an oil collection structure for a food conveyor. This structure utilizes the vibration generated when an elastic rubber ball collides with a baffle bar, transmitting the vibration to a mesh conveyor belt to dislodge food debris adhering to it. However, because the elastic rubber ball directly applies force to the baffle bar, it is prone to damage. Utility Model Content

[0004] The purpose of this application is to provide a material lifting machine that solves the problem that existing food lifting machines easily damage the baffles when cleaning food scraps on the mesh conveyor belt.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A material hoist is provided, comprising: a frame, a drive wheel, a mesh conveyor belt, and baffles. The drive wheel is mounted on the frame and drives the mesh conveyor belt to move. The baffles are fixedly mounted on the outer surface of the mesh conveyor belt. The hoist further comprises a support housing, a lifting cylinder, and a vibrating block. The support housing is fixedly mounted on the frame and located inside the mesh conveyor belt. The lifting cylinder is fixedly mounted vertically on the support housing, with its extension rod pointing vertically downwards. The top of the vibrating block is fixedly connected to the extension rod. The lifting cylinder drives the vibrating block to reciprocate vertically, and the vibrating block applies a downward force to the inner surface of the mesh conveyor belt, thereby causing the mesh conveyor belt to vibrate.

[0006] In one possible implementation, the two ends of the vibrating block along its length are flush with the two ends of the mesh conveyor belt along its width.

[0007] In one possible implementation, a flexible pad is mounted on the bottom of the vibrating block, and the vibrating block contacts the inner surface of the mesh conveyor belt through the flexible pad.

[0008] In one possible implementation, guide rods are fixedly installed on the two outer sidewalls in the width direction of the vibrating block, and guide grooves that slide in cooperation with the guide rods are provided on the support housing.

[0009] In one possible implementation, a limiting ring is fitted and fixed on the guide rod, the limiting ring being located outside the support housing and fitting against the outer side wall of the support housing.

[0010] In one possible implementation, the vibrating block has an internal cavity, the flexible pad seals the bottom opening of the cavity, the flexible pad has an exhaust hole that penetrates the flexible pad vertically, and an air pump is fixedly installed on the support housing. The air pump is connected to the cavity through a hose and is used to deliver high-pressure gas into the cavity.

[0011] In one possible implementation, the lifting cylinder is a front flange type cylinder.

[0012] In one possible implementation, a protective cover is detachably mounted on the top of the support housing, the protective cover housing the lifting cylinder inside.

[0013] In one possible implementation, a collection trough is fixedly mounted on the frame, the collection trough being located outside the mesh conveyor belt, and the top of the collection trough being an open structure located directly below the vibrating block.

[0014] In one possible implementation, a filter screen is installed inside the collection tank.

[0015] Compared with the prior art, the material hoist of this application has a support housing fixedly installed on the frame. The support housing is located inside the mesh conveyor belt. A lifting cylinder is fixedly installed on the support housing in the vertical direction. The telescopic rod of the lifting cylinder is vertically downward, and the top of the vibrating block is fixedly installed on the telescopic rod. Therefore, the lifting cylinder can drive the vibrating block to reciprocate in the vertical direction. During the downward movement, the vibrating block will contact the inner surface of the mesh conveyor belt, thereby applying an intermittent downward force to the mesh conveyor belt, which will cause the mesh conveyor belt to vibrate. Food scraps adhering to the mesh conveyor belt will be shaken off, thereby achieving the purpose of cleaning food scraps on the mesh conveyor belt. Since the baffle is located on the outer surface of the mesh conveyor belt and the vibrating block is located inside the mesh conveyor belt, the force applied by the vibrating block will not directly act on the baffle, thereby avoiding damage to the baffle and extending the service life of the baffle.

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0020] Please refer to the following: Figure 1 and Figure 2This application describes a material hoist. The material hoist includes: a frame 1, a drive wheel 101, a mesh conveyor belt 102, and baffles 103. The drive wheel 101 is mounted on the frame 1 and drives the mesh conveyor belt 102. The baffles 103 are fixedly mounted on the outer surface of the mesh conveyor belt 102. It also includes a support housing 201, a lifting cylinder 202, and a vibrating block 203. The support housing 201 is fixedly mounted on the frame 1 and located inside the mesh conveyor belt 102. The lifting cylinder 202 is fixedly mounted vertically on the support housing 201, with its extension rod pointing vertically downwards. The top of the vibrating block 203 is fixedly connected to the extension rod. The lifting cylinder 202 drives the vibrating block 203 to reciprocate vertically, and the vibrating block 203 applies a downward force to the inner surface of the mesh conveyor belt 102, thereby causing the mesh conveyor belt 102 to vibrate.

[0021] This embodiment provides a material hoist that, compared to existing technologies, has a support housing 201 fixedly mounted on the frame 1. The support housing 201 is located inside the mesh conveyor belt 102. A lifting cylinder 202 is fixedly mounted vertically on the support housing 201, with its extension rod pointing vertically downwards. The top of a vibrating block 203 is fixedly mounted on the extension rod. Therefore, the lifting cylinder 202 can drive the vibrating block 203 to reciprocate vertically. During its downward movement, the vibrating block 203 contacts the inner surface of the mesh conveyor belt 102. Applying an intermittent downward force to the mesh conveyor belt 102 causes it to vibrate, dislodging food debris adhering to the belt and thus cleaning it. Since the baffle 103 is located on the outer surface of the mesh conveyor belt 102, while the vibrating block 203 is located inside, the force applied by the vibrating block 203 does not directly act on the baffle 103, thus avoiding damage and extending its service life.

[0022] In some embodiments, please refer to Figure 2 and Figure 5The two ends of the vibrating block 203 along its length are flush with the two ends of the mesh conveyor belt 102 along its width. In this embodiment, the vibrating block 203 is a rectangular block, with its length aligned with the width of the mesh conveyor belt 102, and both ends of its length flush with the width of the mesh conveyor belt 102. Therefore, the lower end of the vibrating block 203 can cover the entire area of ​​the mesh conveyor belt 102 along its width, allowing the mesh conveyor belt 102 to vibrate synchronously across its width, ensuring that food residue in all areas of the mesh conveyor belt 102 is cleaned up effectively. The bottom of the vibrating block 203 is an arc surface, and the contact surface between the vibrating block 203 and the mesh conveyor belt 102 is also an arc surface, thus avoiding sharp corners when the vibrating block 203 contacts the mesh conveyor belt 102. Therefore, the vibrating block 203 will not cause indentations on the mesh conveyor belt 102.

[0023] In some embodiments, please refer to Figure 2 and Figure 3 A flexible pad 204 is installed at the bottom of the vibrating block 203, and the vibrating block 203 contacts the inner surface of the mesh conveyor belt 102 through the flexible pad 204. In this embodiment, the flexible pad 204 is made of food-grade polyurethane material. Food-grade polyurethane material combines the high elasticity of rubber and the rigidity of plastic, with high tear strength and abrasion resistance 3-5 times that of rubber. Food-grade polyurethane material has a wide temperature range, typically remaining stable from -40℃ to 150℃, and its temperature resistance can be increased to 150℃ after modification. It is resistant to oil, acids and alkalis, and salt water corrosion. When fried food is on the mesh conveyor belt 102, its temperature is generally below 100℃ due to natural cooling, so the flexible pad 204 can operate normally under this ambient temperature. Because the flexible pad 204 has a certain degree of elasticity, it acts as a buffer when the vibrating block 203 contacts the mesh conveyor belt 102, preventing rigid collisions between the vibrating block 203 and the mesh conveyor belt 102, and also avoiding excessive noise. The bottom surface of the vibrating block 203 has two dovetail grooves 205, both extending along the length of the vibrating block 203. The top of the flexible pad 204 has a connecting block that engages with the dovetail grooves 205. The connecting block and the flexible pad 204 are integrally formed. The dovetail grooves 205 effectively restrict the vertical freedom of the flexible pad 204 while ensuring the connection strength between the flexible pad 204 and the vibrating block 203. The outer contour of the flexible pad 204 is the same as that of the vibrating block 203.

[0024] In some embodiments, please refer to Figure 2 and Figure 5Guide rods 206 are fixedly installed on the two outer side walls of the vibrating block 203 in the width direction, and guide grooves 207 that slide with the guide rods 206 are provided on the support housing 201. In this embodiment, there are two guide rods 206, symmetrically arranged on the two outer side walls of the vibrating block 203 in the width direction. Each guide rod 206 is located at the center position in the length direction of the vibrating block 203. The guide rods 206 are cylindrical rods, and guide grooves 207 that slide with the guide rods 206 are provided on the side walls of the support housing 201. The guide grooves 207 can effectively limit the degree of freedom of the vibrating block 203 in the length direction of the vibrating block 203 through the guide rods 206, thereby ensuring that the vibrating block 203 moves more smoothly under the drive of the lifting cylinder 202. Since the two guide rods 206 are symmetrically arranged on both sides of the vibrating block 203 in the width direction, the support housing 201 applies forces to both sides of the vibrating block 203 in the width direction simultaneously through the guide rods 206, thereby ensuring that the force on the vibrating block 203 is more balanced. The guide groove 207 is an elongated hole, and the guide rod 206 makes line contact with the guide groove 207, thereby reducing the frictional resistance between them. One end of the guide rod 206 is threadedly connected to the outer wall of the vibrating block 203, and the outer wall of the vibrating block 203 has a threaded hole that matches the guide rod 206. The threaded connection between the guide rod 206 and the vibrating block 203 facilitates the assembly and disassembly of the guide rod 206. The free end of the guide rod 206 extends through the guide groove 207 to the outside of the support housing 201, so the operator can assemble and disassemble the guide rod 206 from the outside of the support housing 201.

[0025] In some embodiments, please refer to Figure 2 and Figure 5 A limiting ring 208 is fitted and fixed on the guide rod 206. The limiting ring 208 is located outside the support housing 201 and fits against the outer wall of the support housing 201. In this embodiment, the guide rod 206 is a screw rod, and the limiting ring 208 is threadedly connected to the guide rod 206. The limiting ring 208 is installed at the end of the guide rod 206 located outside the support housing 201. The outer wall of the support housing 201 that fits against the limiting ring 208 is a vertical surface. Therefore, when the limiting ring 208 moves up and down with the guide rod 206, the limiting ring 208 slides on the outer wall of the support housing 201. The limiting rings 208 on the two guide rods 206 respectively fit against the two outer walls of the support housing 201 in the width direction, thereby limiting the degree of freedom of the vibrating block 203 to move in its width direction. By installing a guide rod 206 and a limiting ring 208 between the vibrating block 203 and the support housing 201, the degree of freedom of the vibrating block 203 in the horizontal direction is restricted, thereby ensuring the stability of the vibrating block 203 in the vertical direction.

[0026] In some embodiments, please refer to Figure 2 and Figure 3The vibrating block 203 has an internal cavity 209. A flexible pad 204 seals the bottom opening of the cavity 209. An exhaust port 210 is provided on the flexible pad 204, penetrating vertically through it. An air pump 211 is fixedly mounted on the support housing 201. The air pump 211 is connected to the cavity 209 via a hose 212 and is used to deliver high-pressure gas into the cavity 209. In this embodiment, the vibrating block 203 has an internal cavity 209 for holding gas. The bottom of the cavity 209 is open, and the flexible pad 204 seals the bottom opening. An exhaust port 210 is provided on the flexible pad 204, penetrating from top to bottom through it, connecting the cavity 209 to the outside. The lower opening of the exhaust port 210 faces the inner surface of the mesh conveyor belt 102. Multiple vents 210 are evenly distributed along the length of the flexible pad 204, allowing them to cover a larger area of ​​the mesh conveyor belt 102. The air pump 211 is fixedly mounted on the inner wall of the support housing 201, thus protecting it and preventing oil spills from the mesh conveyor belt 102 from contaminating it. The air pump 211 is connected to the receiving cavity 209 via a flexible hose 212. The hose 212 is flexible and can be bent and extended. The length of the hose 212 is greater than the distance between the air pump 211 and the vibrating block 203, allowing the connection between the hose 212 and the vibrating block 203 to move up and down together. The air pump 211 is connected to an external air source. The air pump 211 compresses the pure gas provided by the air source into high-pressure gas and delivers it to the receiving cavity 209 through the hose 212. Finally, it is discharged from the exhaust hole 210 on the flexible pad 204. The high-pressure gas is blown towards the food scraps through the mesh on the mesh conveyor belt 102. Under the combined action of the high-pressure gas and the vibration of the mesh conveyor belt 102, the food scraps adhering to the mesh conveyor belt 102 can be quickly detached downwards, thereby achieving rapid cleaning of the mesh conveyor belt 102.

[0027] In some embodiments, please refer to Figure 2 and Figure 4The lifting cylinder 202 is a front flange type cylinder. In this embodiment, the front flange type cylinder is fixed to the support housing 201 by a flange, and the flange is located at the end of the cylinder body near its telescopic rod. Since the flange is fixed to the top surface of the support housing 201 by screws, the cylinder body of the lifting cylinder 202 is located outside the support housing 201, thus effectively reducing the height of the support housing 201. This saves material costs for the support housing 201 and reduces the space occupied by the support housing 201. The support housing 201 has clearance holes for the telescopic rod to pass through. The connection between the telescopic rod of the lifting cylinder 202 and the vibrating block 203 is located at the center of the top surface of the vibrating block 203, thereby ensuring that the force exerted by the vibrating block 203 on the telescopic rod is consistent with the axis of the telescopic rod. A connecting column 213, which is cylindrical, is welded and fixed to the top of the vibrating block 203. The connecting post 213 has an installation hole that matches the telescopic rod. The lower end of the telescopic rod is inserted into the installation hole, and the connecting post 213 locks and fixes the telescopic rod with a set screw 214.

[0028] In some embodiments, please refer to Figure 2 and Figure 5 A protective cover 215 is detachably installed on the top of the support housing 201, and the protective cover 215 encloses the lifting cylinder 202 inside it. In this embodiment, since the cylinder body of the lifting cylinder 202 is exposed outside the support housing 201, in order to prevent oil from the mesh conveyor belt 102 from falling onto the lifting cylinder 202, a protective cover 215 is installed on the top of the support housing 201. The protective cover 215 encloses the lifting cylinder 202 inside it, thereby protecting the lifting cylinder 202.

[0029] In some embodiments, please refer to Figure 1 A collection trough 216 is fixedly installed on the frame 1. The collection trough 216 is located outside the mesh conveyor belt 102, and its top is open and directly below the vibrating block 203. In this embodiment, when the mesh conveyor belt 102 transports fried food, food scraps and oil will remain. In order to collect the food scraps and oil, the collection trough 216 is fixedly installed on the frame 1. The collection trough 216 is located outside and below the mesh conveyor belt 102, and the top opening of the collection trough 216 faces the vibrating block 203, so the collection trough 216 is directly below the vibrating block 203. Under the action of vibration and high-pressure airflow, food scraps and oil will fall from the mesh conveyor belt 102 near the vibrating block 203 into the collection tank 216, thereby collecting food scraps and oil. On the one hand, this can prevent food scraps and oil from polluting the surrounding environment, and on the other hand, it can recycle oil and reduce oil waste.

[0030] In some embodiments, please refer to Figure 1 A filter screen 217 is installed inside the collection tank 216. In this embodiment, the filter screen 217 is fixedly installed horizontally inside the collection tank 216. The filter screen 217 is used to filter food scraps, thereby separating food scraps from oil. To facilitate the removal of oil from the collection tank 216, an oil outlet can be provided at the bottom of the collection tank 216, and a valve can be installed to control the opening and closing of the oil outlet.

[0031] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 The width direction of the frame 1 is consistent with the width direction of the mesh conveyor belt 102. The support housing 201 is a U-shaped part with the opening facing downward. The support housing 201 is set along the width direction of the frame 1. An assembly hole 218 is opened on one side of the frame 1 in the width direction. The outer contour of the assembly hole 218 is larger than the outer contour of the support housing 201, the lifting cylinder 202 and the vibrating block 203 as a whole. Therefore, it is convenient to assemble the support housing 201, the lifting cylinder 202 and the vibrating block 203 into the interior of the mesh conveyor belt 102 from the outside of the frame 1. One end of the support housing 201 passes through the assembly hole 218 into the interior of the frame 1 and finally abuts against the inner side wall of the frame 1. Then, the support housing 201 is fixed to the frame 1 by screws. The other end of the support housing 201 (the end near the assembly hole 218) is fixedly installed with a sealing plate 219. The outer contour of the sealing plate 219 is larger than the outer contour of the assembly hole 218. The sealing plate 219 is always located outside the frame 1. When the support housing 201 is installed in place, the sealing plate 219 is just in contact with the outer side wall of the frame 1. The sealing plate 219 is fixedly connected to the frame 1 by screws.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
