Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a sesame oil filling device. Background Technology

[0002] With the improvement of people's living standards, the market demand for sesame oil, as a common condiment, is increasing. In the bottling process of sesame oil production enterprises, efficient and precise filling equipment is crucial to product quality and production efficiency. In the traditional sesame oil filling process, traditional filling equipment lacks effective fixing methods when positioning the sesame oil container. For example, a sesame oil injection filling device patent with patent number "CN202321841967.3" is prone to container displacement on the conveyor belt, causing the oil gun and container opening to misalign. This not only results in sesame oil filling position deviation but also easily leads to sesame oil spillage, wasting raw materials and increasing cleaning costs. Furthermore, due to the lack of a stable clamping structure, the container may shake during the filling process, affecting the accuracy of the filling volume.

[0003] Currently, most traditional filling equipment uses a single filling gun to fill containers one by one, resulting in slow filling speeds that cannot keep up with the ever-increasing market order volume. Furthermore, the lifting and leveling adjustments of the filling gun are not flexible enough, making it difficult to quickly adjust the filling position according to different container sizes. There are also issues such as the inability to adjust the filling height based on bottle height; the filling gun cannot automatically adapt to the optimal filling height, which can easily lead to splattering of sesame oil during filling, and excessively long filling distances can affect filling accuracy and speed. Utility Model Content

[0004] The purpose of this invention is to provide a sesame oil filling device that can adapt to different bottle sizes and enable simultaneous filling of multiple bottles, addressing the above-mentioned problems.

[0005] To achieve the above objectives, this utility model discloses a sesame oil filling device, including a frame with a conveyor belt. The device features a support frame on one side of the frame, a positioning bracket extending above the conveyor belt on the support frame, a clamping mechanism adapted to the conveying direction of the conveyor belt on the lower end of the positioning bracket, a lifting bracket on the upper end of the positioning bracket, a horizontally positioned limiting plate on the lifting bracket, and multiple vertically positioned oil guns on the limiting plate.

[0006] With the above structure, a complete filling system is formed by setting a support frame, positioning bracket, clamping mechanism, lifting bracket, limiting plate, and multiple oil guns on one side of the conveyor belt. The clamping mechanism can accurately fix the container, which can effectively solve the problem of inaccurate container positioning and clamping in traditional devices, and avoid filling position deviation and oil spillage caused by bottle displacement during the filling process. The lifting bracket, in conjunction with the limiting plate and multiple oil guns, can flexibly adjust the downward extension distance of the oil guns during oil injection, which can improve filling accuracy and speed. The simultaneous operation of multiple oil guns, compared with the traditional single oil gun operation, greatly improves filling efficiency and meets the needs of large-scale production.

[0007] Preferably, the support frame includes a strip mounting plate fixed horizontally to one side of the conveyor belt frame. The strip mounting plate is arranged along the length of the frame, and two support rods are spaced apart on the strip mounting plate. Each support rod has a sleeve that slides along its length, and each sleeve has a locking bolt passing through it. This support frame uses a structure of strip mounting plate, support rods, sleeves, and locking bolts. The position of the sleeves on the support rods can be adjusted by the locking bolts.

[0008] Preferably, the positioning bracket includes a first positioning plate connected horizontally to the two sleeves, and a second positioning plate extending horizontally along the conveyor belt direction, the extension direction of the second positioning plate being perpendicular to the conveyor belt direction. This positioning bracket, composed of the first and second positioning plates, ensures accurate and stable positioning. The first positioning plate, connected to the sleeves, securely connects the support frame and the positioning bracket, facilitating adjustment of the overall filling mechanism's height by adjusting the support frame's height. The second positioning plate, extending vertically along the conveyor belt direction, provides a precise installation positioning reference for the clamping mechanism and the lifting bracket, ensuring accurate positional relationships between components, enabling accurate clamping and filling of the container on the conveyor belt, and improving the stability of the entire filling process.

[0009] Preferably, the clamping mechanism includes a first clamping plate fixed to the positioning bracket, a first control cylinder disposed on the rear side wall of the first clamping plate, the control rod of the first control cylinder passing through the first clamping plate horizontally and extending to directly above the conveyor belt, the control rod of the first control cylinder being perpendicular to the conveying direction of the conveyor belt, two guide posts being vertically fixed to the front side wall of the first clamping plate, a second clamping plate parallel to the first clamping plate being fixed to the outer end of the control rod of the first control cylinder, two positioning through holes being disposed on the second clamping plate and the positions of the two positioning through holes corresponding to the two guide posts, and a plurality of corresponding clamping blocks being disposed at intervals on the lower bottom of the first clamping plate and the second clamping plate respectively. By using the first control cylinder on the first clamping plate to drive the second clamping plate to move, and in conjunction with the guide post and the positioning through hole on the second clamping plate, the relative movement between the second clamping plate and the first clamping plate is achieved, thereby stably clamping the container. At the same time, the first control cylinder and the clamping block can provide a stable clamping force, and the guide post can ensure the linearity and stability of the movement of the second clamping plate, prevent the clamping plate from deviating, and further ensure that the container is firmly clamped, avoiding container shaking during the filling process from affecting the filling accuracy.

[0010] Preferably, the first and second clamping plates are L-shaped baffles of the same size, with the vertical length of the L-shaped baffle being shorter than the horizontal length. The upper end of the vertical plate of the first clamping plate is vertically fixed to the lower end face of the second positioning plate on the positioning bracket. The extension direction of the horizontal plate of the first clamping plate is the same as the conveyor belt's conveying direction. The second clamping plate is parallel to the first clamping plate, and its rear sidewall is perpendicularly connected to the control rod of the first control cylinder. By using an L-shaped baffle structure for the first and second clamping plates, with the vertical plate used for installation and the horizontal plate extending in the same direction as the conveyor belt's conveying direction, this structural design provides the clamping plates with a certain guiding function and offers more clamping positions and space, thereby enabling the simultaneous clamping of multiple bottles.

[0011] Preferably, the clamping block is a rectangular stop made of PVC. Corresponding clamping openings are provided on the adjacent sidewalls of the front and rear clamping blocks on the first and second clamping plates. A fixing bolt passes through the lower end face of the clamping block and secures it to the first or second clamping plate. By using PVC material and providing clamping openings, the clamping blocks benefit from the elasticity of the PVC material, ensuring clamping force on the container while preventing damage to the container surface. The design of the clamping openings allows for adaptation to the container shape and improves clamping stability. Furthermore, installing the clamping blocks with fixing bolts facilitates adjustment of their installation position to accommodate the clamping requirements of containers of different sizes.

[0012] Preferably, the lifting bracket includes two positioning rods vertically fixed to the positioning bracket. The two positioning rods are spaced apart along the length of the second positioning plate. A lifting plate, positioned horizontally, connects the two positioning rods and moves up and down along the length of the positioning rods. A connecting plate, fixed to the upper end of the two positioning rods, is provided on the connecting plate, and a second control cylinder is provided on the connecting plate to control the up and down movement of the lifting plate along the positioning rods. The lifting bracket consists of positioning rods, a lifting plate, a connecting plate, and a second control cylinder. The second control cylinder drives the lifting plate to move up and down along the positioning rods, realizing the sinking and lifting of the oil gun during oil filling, thereby ensuring that the oil gun is at the optimal filling height, effectively preventing sesame oil splashing, and improving filling accuracy and speed.

[0013] Preferably, the second control cylinder is a stroke-adjustable cylinder, and the lower end of the control rod of the second control cylinder is vertically fixed to the upper surface of the lifting plate. By using a stroke-adjustable cylinder for the second control cylinder, the moving distance of the lifting plate can be precisely adjusted according to actual needs, thereby precisely controlling the lifting height of the oil gun. In this way, whether the sesame oil bottle is short or tall, the oil gun can accurately reach the appropriate filling position by adjusting the cylinder stroke, further improving the filling accuracy and the applicability of the equipment.

[0014] Preferably, a limiting plate is vertically fixed to the left side wall of the lifting plate of the lifting support. The limiting plate is a strip-shaped plate located directly above the conveyor belt, and its extension direction is the same as the conveying direction of the conveyor belt. Multiple mounting ports for installing oil injection guns are spaced apart along the length of the limiting plate. By setting a limiting plate on the lifting plate of the lifting support, which is located directly above the conveyor belt and has multiple mounting ports for installing oil injection guns, the limiting plate provides stable mounting support for the oil injection guns, thus ensuring the positional stability of the oil injection guns during the filling process. Furthermore, multiple mounting ports can accommodate multiple oil injection guns, enabling simultaneous filling of multiple containers and improving filling efficiency.

[0015] Preferably, an oil gun is provided at the mounting port, with its injection nozzle extending through the mounting port to the clamping mechanism and located directly above the clamping block. By mounting the oil gun at the mounting port of the limiting plate and positioning the injection nozzle directly above the clamping block, this layout ensures accurate alignment between the oil gun and the clamped container opening, guaranteeing precise injection of sesame oil into the container and preventing spillage due to positional deviation.

[0016] In summary, the beneficial effects of this utility model are as follows: This utility model can adapt to filling different types of bottles and can realize the simultaneous filling of multiple bottles. By setting a support frame, positioning bracket, clamping mechanism, lifting bracket, limiting plate and multiple oil guns on one side of the machine frame conveyor belt, a complete filling system is formed. Among them, the clamping mechanism can accurately fix the container, which can effectively solve the problem of inaccurate container positioning and clamping in traditional devices, and avoid filling position deviation and oil spillage caused by bottle displacement during the filling process. The lifting bracket, in conjunction with the limiting plate and multiple oil guns, can flexibly adjust the downward extension distance of the oil guns during oil injection, which can improve filling accuracy and speed. The simultaneous operation of multiple oil guns, compared with the traditional single oil gun operation, greatly improves filling efficiency and meets the needs of large-scale production.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this application.

[0024] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly, for example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] The following is a description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0026] like Figure 1 and Figure 2As shown, this utility model includes a frame 1, with a bottle conveyor belt 2 for sesame oil filling mounted on the upper surface of the frame 1. The frame 1 and bottle conveyor belt 2 are existing technologies and will not be described in detail here. In the design, a support frame 3 is mounted on one side of the frame 1 along the conveyor belt 2. A positioning bracket 4 extending above the conveyor belt 2 is mounted on the support frame 3. The support frame 3 includes a strip mounting plate 9 fixed horizontally to one side of the frame 1 along the conveyor belt 2. The strip mounting plate 9 is arranged along the length of the frame 1, and two support rods 10 are spaced apart on the strip mounting plate 9. Sleeves 11 that slide along the length of the support rods 10 are respectively fitted onto the two support rods 10. Locking bolts 12 passing through the sleeves 11 are respectively provided on the two sleeves 11. In manufacturing, the positioning bracket 4 includes a first positioning plate 13 connected horizontally to the two sleeves 11. A second positioning plate 14 extending horizontally along the direction of the conveyor belt 2 is mounted on the first positioning plate 13. The second positioning plate 14... The extension direction is perpendicular to the conveying direction of the conveyor belt 2. This allows for adjustment of the position of the sleeve 11 on the support rod 10 and fixation by the locking bolt 12. By controlling the locking bolt 12, the height of the first positioning plate 13 can be flexibly changed, thereby adjusting the overall height of the filling mechanism on the positioning bracket 4. This adapts to filling operations with different bottle heights. Furthermore, the positioning bracket 4 consists of a first positioning plate 13 and a second positioning plate 14. This structural design ensures accurate and stable positioning. The first positioning plate 13 is connected to the sleeve 11, firmly connecting the support frame 3 and the positioning bracket 4. This allows for easy adjustment of the overall height of the filling mechanism by adjusting the height of the support frame 3. Simultaneously, the second positioning plate 14 extends vertically along the conveyor belt 2, providing a precise installation positioning reference for other mechanisms of the filling device. This ensures accurate positional relationships between components, enabling containers to be accurately clamped and filled on the conveyor belt 2, thus improving the stability of the entire filling process.

[0027] like Figures 1-3As shown, a clamping mechanism 5 adapted to the conveying direction of the conveyor belt 2 is provided on the lower end of the positioning bracket 4. The clamping mechanism 5 includes a first clamping plate 15 fixed to the positioning bracket 4. A first control cylinder 16 is provided on the rear side wall of the first clamping plate 15. The control rod of the first control cylinder 16 passes through the first clamping plate 15 horizontally and extends to directly above the conveyor belt 2. The control rod of the first control cylinder 16 is perpendicular to the conveying direction of the conveyor belt 2. In the design, two guide posts 17 are vertically fixed to the front side wall of the first clamping plate 15. The two guide posts 17 are parallel to each other and are not in the same vertical plane or the same horizontal plane. The outer end of the control rod of the first control cylinder 16 is fixed to a second clamping plate 18 parallel to the first clamping plate 15. At the same time, two positioning through holes are provided on the second clamping plate 18. The two positioning through holes correspond to the positions of the two guide posts 17, thereby allowing the second clamping plate 18 to move along the guide posts 17 under the control of the first control cylinder 16. During manufacturing, multiple corresponding clamping blocks 19 are also provided at intervals on the lower bottom of the first clamping plate 15 and the second clamping plate 18. In this way, by using the first control cylinder 16 on the first clamping plate 15 to drive the second clamping plate 18 to move, and cooperating with the positioning through holes on the guide posts 17 and the second clamping plate 18, the relative movement of the second clamping plate 18 and the first clamping plate 15 is realized, thereby achieving stable clamping of the container. At the same time, the first control cylinder 16 and the clamping blocks 19 can provide a stable clamping force, and the guide posts 17 can ensure the linearity and stability of the movement of the second clamping plate 18, further preventing the clamping plate from deviating and ensuring that the container is firmly clamped, avoiding the container shaking during the filling process and affecting the accuracy of the filling volume.

[0028] like Figures 2-4As shown, the first clamping plate 15 and the second clamping plate 18 are L-shaped baffles of the same size. The length of the vertical plate of the L-shaped baffle is less than the length of the horizontal plate. The upper end of the vertical plate of the first clamping plate 15 is vertically fixed to the lower end face of the second positioning plate 14 on the positioning bracket 4. The extension direction of the horizontal plate of the first clamping plate 15 is the same as the conveying direction of the conveyor belt 2. In this way, by adopting an L-shaped baffle structure for the first clamping plate 15 and the second clamping plate 18, with the vertical plate used for installation and the horizontal plate extending in the same direction as the conveyor belt 2, this structural design gives the clamping plate a certain guiding function and provides more clamping positions and space, thereby realizing the synchronous clamping of multiple bottles. In the design, the second clamping plate 18 is parallel to the first clamping plate 15, and the rear side wall of the second clamping plate 18 is perpendicularly connected to the control rod of the first control cylinder 16. This, in conjunction with the guide post 17 and the positioning through hole on the second clamping plate 18, enables relative movement between the second clamping plate 18 and the first clamping plate 15. In manufacturing, the clamping block 19 is a rectangular block made of PVC. The adjacent side walls of the front and rear clamping blocks 19 on the first clamping plate 15 and the second clamping plate 18 are provided with corresponding clamping openings 20. By using PVC material for the clamping blocks 19 and providing clamping openings 20, the PVC material has a certain elasticity, which can ensure the clamping force on the container and avoid damage to the container surface. The design of the clamping openings 20 can be adapted to the shape of the container and improve the stability of the clamping. Meanwhile, a fixing bolt 21 is provided on the lower end face of the clamping block 19, which passes through the clamping block 19 and fixes the clamping block 19 on the first clamping plate 15 or the second clamping plate 18. Usually, multiple threaded holes that match the fixing bolt 21 can be provided at intervals on the lower end face of the first clamping plate 15 and the second clamping plate 18, so as to facilitate flexible adjustment of the relative position of the clamping block 19 and thus adapt to the clamping requirements of containers of different specifications.

[0029] like Figures 1-3As shown, a lifting bracket 6 is provided on the upper end of the positioning bracket 4. The lifting bracket 6 is also provided with a limiting plate 7 arranged in the horizontal direction. The limiting plate 7 is provided with a plurality of oil injection guns 8 arranged in the vertical direction. In the design, the lifting bracket 6 includes two positioning rods 22 vertically fixed to the positioning bracket 4. The two positioning rods 22 are spaced apart along the length direction of the second positioning plate 14. A lifting plate 23 arranged in the horizontal direction is connected between the two positioning rods 22 and the lifting plate 23 moves up and down along the length direction of the positioning rods 22. Usually, the lifting plate 23 is a strip plate and a circular opening with a diameter adapted to the two positioning rods 22 is provided near the two ends of the strip plate. The two positioning rods 22 pass through the circular openings respectively. In the manufacturing process, a connecting plate 24 is provided on the upper end of the two positioning rods 22 and fixed to the two positioning rods 22. A second control cylinder 25 is installed on the connecting plate 24 to control the lifting plate 23 to move up and down along the positioning rods 22. In this way, the lifting plate 23 is driven by the second control cylinder 25 to move up and down along the positioning rod 22, thereby realizing the sinking and lifting of the limit plate 7 and the oil gun 8 during oil filling, thus ensuring that the oil gun 8 is at the optimal filling height, effectively preventing sesame oil from splashing, and improving filling accuracy and speed.

[0030] like Figures 1-3 As shown, the second control cylinder 25 is an adjustable-stroke cylinder, and the lower end of the control rod of the second control cylinder 25 is vertically fixed to the upper surface of the lifting plate 23. By using an adjustable-stroke cylinder for the second control cylinder 25, the moving distance of the lifting plate 23 can be precisely adjusted according to actual needs, thereby precisely controlling the lifting height of the oil gun 8. In this way, regardless of whether the sesame oil bottle is short or tall, the oil gun 8 can accurately reach the appropriate filling position by adjusting the cylinder stroke, further improving the filling accuracy and the applicability of the equipment. Of course, to ensure the stability of the adjustable-stroke cylinder during operation, a reinforcing plate is also provided on the upper end of the support frame 3 for further fixing the adjustable-stroke cylinder.

[0031] like Figures 1-3As shown, a limiting plate 7 is vertically fixed to the left side wall of the lifting plate 23 of the lifting bracket 6. This limiting plate 7 is a strip-shaped plate located directly above the conveyor belt 2. In design, the extension direction of the limiting plate 7 is the same as the conveying direction of the conveyor belt 2. Multiple mounting ports 26 for installing oil injection guns 8 are spaced apart along the length of the limiting plate 7. Thus, by setting the limiting plate 7 on the lifting plate 23 of the lifting bracket 6, with the limiting plate 7 located directly above the conveyor belt 2 and having multiple mounting ports 26 for installing oil injection guns 8, the limiting plate 7 can provide stable mounting support for the oil injection guns 8, thereby ensuring the positional stability of the oil injection guns 8 during the filling process. Multiple mounting ports 26 can accommodate multiple oil injection guns 8, enabling simultaneous filling of multiple containers and improving filling efficiency. During manufacturing and installation, an oil injection gun 8 is installed at the mounting port 26, positioned vertically. The oil injection port of the oil injection gun 8 extends through the mounting port 26 to the clamping mechanism 5 position, located directly above the clamping block 19. By mounting the oil gun 8 at the mounting port 26 of the limiting plate 7 with the oil inlet directly above the clamping block 19, this layout ensures accurate alignment between the oil gun 8 and the clamped container opening, guaranteeing precise injection of sesame oil into the container and preventing spillage due to positional deviation. In actual production, the sesame oil bottle is conveyed to the filling area via the conveyor belt 2, where the clamping mechanism 5 automatically secures it. The lifting bracket 6 adjusts the position of the oil gun 8 according to the bottle height, and then multiple oil guns 8 simultaneously perform filling operations. The filled sesame oil bottle is then conveyed out by the conveyor belt 2. The entire process is seamless and efficient, effectively solving the problems of inaccurate positioning and low efficiency found in traditional filling devices.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
