Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Please see Figure 1 and Figure 2This utility model provides a technical solution: a catering frying equipment with a quick-change filter screen, including a fryer 110 and a filter basket 120. A base 130 is fixedly installed at the bottom of the fryer 110. A sliding groove is provided on one side of the top of the fryer 110. A U-shaped frame 150 is slidably installed on the inner wall of the sliding groove. A lifting component is installed at the bottom of the U-shaped frame 150. A support plate 140 is rotatably installed at the top of the U-shaped frame 150. A frying tank is provided at the top of the fryer 110. The filter basket 120 is slidably connected to the inner wall of the frying tank. A support frame 121 is fixedly installed at the top of the filter basket 120. A support block 122 is fixedly installed on one side of the top of the support frame 121. A first slot matching the support plate 140 is provided on one side of the support block 122. Positioning components are symmetrically installed inside the support plate 140.

[0029] In some specific implementations, a support groove matching the support frame 121 is provided at the top of the frying tank. The support frame 121 is slidably connected to the inner wall of the support groove, and the size of the support frame 121 is larger than the size of the filter basket 120. The sliding fit between the support frame 121 and the support groove can horizontally limit the filter basket 120, preventing it from shaking during frying. The larger size of the support frame 121 allows it to be stably mounted at the top of the frying tank, preventing the filter basket 120 from falling completely to the bottom of the frying tank, and facilitating quick positioning and removal during replacement.

[0030] In some specific implementations, a collection tray 131 is hinged to one side of the base 130. The hinge point between the collection tray 131 and the base 130 has resistance, requiring manual pushing of the collection tray 131 to rotate. The collection tray 131 can collect waste oil dripping during filter basket 120 replacement, preventing oil contamination of the ground below the equipment. The resistance design at the hinge prevents the collection tray 131 from opening automatically due to vibration, ensuring a tight seal during normal use. Simultaneously, the manual pushing operation allows for precise control of the opening angle, improving cleaning convenience.

[0031] Please see Figure 3 and Figure 4 The lifting assembly includes a threaded sleeve 151 and a threaded rod 152. The threaded rod 152 is rotatably mounted on the bottom of the inner wall of the slide groove, and the threaded sleeve 151 is fixedly mounted on the top of the inner wall of the U-shaped frame 150. The bottom end of the threaded sleeve 151 is threadedly connected to the top end of the threaded rod 152. A drive assembly is installed at the bottom end of the threaded rod 152, and the threaded rod 152 is located at the center of the slide groove. The threaded transmission between the threaded sleeve 151 and the threaded rod 152 can convert the rotational motion of the motor 156 into the vertical lifting motion of the U-shaped frame 150, realizing the automatic lifting of the filter basket 120. The centrally located threaded rod 152 ensures that the U-shaped frame 150 is evenly stressed, preventing tilting during lifting and improving the stability of the movement.

[0032] In some specific implementation schemes, guide blocks 153 are symmetrically fixedly installed on the outer bottom end of the U-shaped frame 150. Guide grooves matching the guide blocks 153 are symmetrically arranged on both sides of the inner wall of the slide groove. The guide blocks 153 are T-shaped and slidably connected to the inner wall of the guide grooves. The sliding cooperation between the T-shaped guide blocks 153 and the guide grooves enhances the guidance and stability of the U-shaped frame 150 during lifting and lowering, prevents the U-shaped frame 150 from shifting laterally or swaying, ensures the filter basket 120 is lifted and lowered vertically, and avoids collision damage with the inner wall of the frying tank.

[0033] In some specific implementations, the drive assembly includes a first rotating shaft 154, a second rotating shaft 155, and a motor 156. A cavity is provided inside the side wall of the fryer 110, located below a sliding groove. The bottom end of a threaded rod 152 is fixedly mounted on the first rotating shaft 154, which passes through the bottom of the sliding groove and is rotatably connected to the bottom end of the inner wall of the cavity. A worm gear is fixedly mounted on the first rotating shaft 154. A second rotating shaft 155 is rotatably mounted on one side of the inner wall of the cavity, and a worm is fixedly mounted on the second rotating shaft 155. The worm gear and worm are connected by a transmission. A motor 156 is fixedly mounted on one end of the second rotating shaft 155, and the motor 156 is fixedly mounted on one side of the cavity. A controller is fixedly mounted on the outside of the fryer 110, and the controller is electrically connected to the motor 156. The worm gear transmission has a self-locking function, preventing the threaded rod 152 from rotating on its own due to load after the motor 156 stops, ensuring that the filter basket 120 remains stably at any height. The controller controls the forward and reverse rotation of the motor 156, automating the lifting process, reducing manual operation intensity, and improving replacement efficiency.

[0034] Please see Figure 5 and Figure 6 The positioning assembly includes a plug 141, a slide plate 142, and a spring 143. A locking cavity is symmetrically arranged within the support plate 140. A partition 144 is fixedly installed on the inner wall of the locking cavity. Springs 143 are symmetrically fixedly installed on both sides of the partition 144. A slide plate 142 is fixedly installed at one end of each spring 143. The plug 141 is fixedly installed on one side of the slide plate 142. One end of the plug 141 slides through the support plate 140 and extends to the outside. Second slots matching the plug 141 are provided on both sides of the inner wall of the first slot. One side of the plug 141 is inclined. Resistance is provided at the rotatable connection between the support plate 140 and the U-shaped frame 150, requiring manual pushing for rotation. The slide plate 142 is slidably connected to the inner wall of the locking cavity. The inclined surface design of the plug 141 allows it to automatically slide into the first slot during filter basket 120 installation, achieving rapid locking in conjunction with the spring force of the spring 143. The resistance design requiring manual pushing for rotation of the support plate 140 prevents it from rotating due to vibration during lifting, ensuring stable and reliable positioning.

[0035] In some specific implementations, guide rods 145 are symmetrically fixedly mounted on both sides of the partition 144, and the slide plate 142 is slidably mounted on the guide rods 145. A spring 143 is sleeved on the outside of the guide rods 145. The guide rods 145 provide a sliding track for the slide plate 142, restricting its direction of movement and preventing the slide plate 142 from shifting under the action of the spring 143. This ensures that the insert block 141 is accurately inserted into or removed from the second slot, improving the reliability and service life of the positioning assembly.

[0036] In some specific implementations, a push plate 146 is fixedly installed on one side of the slide plate 142. One end of the push plate 146 slides through the support plate 140 and extends to the outside. A strip-shaped hole matching the push plate 146 is provided on one side of the support plate 140. Sealing strips 147 are symmetrically fixedly installed on both sides of the support plate 140. Sealing grooves matching the sealing strips 147 are provided on both sides of the inner wall of the strip-shaped hole. The sealing strips 147 are slidably connected to the inner wall of the sealing grooves. The push plate 146 is slidably connected to the inner wall of the strip-shaped hole, and one end of the push plate 146 is arc-shaped. The arc-shaped end of the push plate 146 makes it easy for the operator to press with their fingers to push the slide plate 142 to compress the spring 143, thereby unlocking the insert block 141. The sealing strip 147 and the sealing groove cooperate to prevent oil fumes and moisture from entering the interior of the support plate 140 during the frying process, avoid the positioning component from getting stuck due to contamination, and improve the sealing performance and durability of the equipment.

[0037] In some specific implementations, guide frames 148 are symmetrically fixedly installed on both sides of the support plate 140. The guide frames 148 are L-shaped, and the support block 122 has L-shaped grooves on both sides that match the guide frames 148. This provides precise guidance, ensuring that the first slot of the support block 122 aligns quickly with the support plate 140, reducing manual alignment time; it also enhances the connection stability between the two, preventing the filter basket 120 from falling off during rotation.

[0038] Working principle: When the filter basket 120 needs to be replaced, the collection tray 131 is opened, the new filter basket 120 is taken out, and the support block 122 at its top is placed on the outside of the support plate 140. The insertion block 141 is pressed back by the inclined surface and stretches the spring 143. When the insertion block 141 is aligned with the second slot, the tension of the spring 143 causes the insertion block 141 to move back and insert into the second slot for fixation. At this time, the motor 156 is started to drive the second rotating shaft 155 to rotate. The rotation of the second rotating shaft 155 drives the first rotating shaft 154 to rotate through the worm and worm wheel. The rotation of the first rotating shaft 154 drives the threaded rod 152 to rotate. The rotation of the threaded rod 152 drives the U-shaped frame 150 to move upward through the threaded sleeve rod 151. Thus, the filter basket 120 is moved upward through the support plate 140 to the frying tank, pushing the new filter basket 120 to rotate 180°. The motor 156 is started again to output in the reverse direction. When moving downward, the angle can be adjusted appropriately according to the needs.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
