Description

Technical Field

[0001] This utility model relates to the field of paste packaging technology, and in particular to a hopper for a paste packaging machine. Background Technology

[0002] A paste packaging machine is a device used to automatically and quantitatively fill viscous paste materials into containers. Most common paste filling machines are pneumatic plunger-type quantitative filling machines. The cylinder drives the piston to draw the material in the hopper into the material pipe through a three-way rotary valve, and then the cylinder drives the material to be pushed out through the three-way rotary valve. The material enters the container from the filling nozzle. The filling amount is controlled by controlling the stroke of the cylinder.

[0003] The hopper of the paste packaging machine is the core component for storing, mixing and conveying paste raw materials, which directly affects the filling accuracy, efficiency and material stability. However, due to the high viscosity of paste materials, the efficiency of manually cleaning the inside of the hopper after the paste is packaged is low. Utility Model Content

[0004] The purpose of this invention is to provide a hopper for a paste packaging machine that improves the cleaning efficiency of the hopper.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: It includes a hopper, a discharge pipe connected to the bottom of the hopper, and a hollow tubular rotating shaft rotatably mounted on the hopper in a horizontal direction. A cover plate is fitted on the top of the hopper, and a vent hole is provided on the cover plate. A drive motor for driving the rotating shaft is provided on the hopper. Several stirring rods are evenly arranged on the rotating shaft. The end of the rotating shaft away from the drive motor passes through the hopper. A hot water pipe is rotatably mounted on the end of the rotating shaft away from the drive motor. A control valve is provided on the hot water pipe. Several cleaning holes are evenly arranged on the rotating shaft. An adjustment mechanism for controlling the opening and closing of the cleaning holes is provided on the hopper.

[0006] A further feature of this invention is that the adjusting mechanism includes a cleaning tube movably fitted to the inner wall of the rotating shaft and a plurality of control holes evenly distributed on the outer wall of the cleaning tube, each corresponding to a cleaning hole. The cross-sectional area of ​​the control holes is larger than that of the cleaning holes. A synchronizing mechanism is provided on the rotating shaft to drive the cleaning tube to rotate synchronously. One end of the cleaning tube is at a set distance from the inner wall of the hopper, and the other end of the cleaning tube is rotatably connected to the hot water pipe. The end of the rotating shaft away from the drive motor is at a set distance from the hot water pipe. A translation mechanism is provided on the hopper to push the cleaning tube to move along the inner wall of the rotating shaft. The translation mechanism can push the outer wall of the cleaning tube to fit against the cleaning hole.

[0007] A further feature of this invention is that the synchronization mechanism includes several elongated slots located at the end of the rotating shaft away from the drive motor, and several locking blocks disposed on the outer wall of the cleaning tube that mate with each slot. When the control hole is in communication with the adjacent cleaning hole, the end of the locking block engages with the slot. When the outer wall of the cleaning tube is in contact with the cleaning hole, the end of the locking block abuts against the end of the slot near the drive motor.

[0008] A further feature of this invention is that the translation mechanism includes a plurality of support rods arranged horizontally on the hopper and a support ring arranged vertically on the plurality of support rods. The hot water pipe moves through the support ring. A translation thread is provided on the outer wall of the end of the hot water pipe near the cleaning pipe. An adjustment ring that cooperates with the translation thread is rotatably provided on the support ring.

[0009] A further feature of this invention is that a limiting ring is provided between several of the support rods, the hot water pipe moves through the limiting ring, and when the end of the locking block abuts against the limiting ring, the other end of the locking block engages with the locking groove, and the control hole and the cleaning hole are in a connected state.

[0010] A further feature of this invention is that a lifting handle is provided on the top of the cover plate.

[0011] A further feature of this invention is that the hopper comprises, from bottom to top, a first hopper body with a semi-circular longitudinal section and a second hopper body with a rectangular longitudinal section, and the end of the stirring rod is movably attached to the inner wall of the first hopper body.

[0012] A further feature of this invention is that a scraper with a circular arc cross-section is provided between several of the stirring rods, and the scraper can be movably attached to the inner wall of the first hopper.

[0013] A further feature of this invention is that the outer wall of the adjusting ring is evenly provided with a plurality of rotating handles.

[0014] The beneficial effects of this utility model are:

[0015] 1. By incorporating a cleaning port and a rotating shaft, when cleaning the hopper is required, the cleaning port is first opened via an adjusting mechanism. Then, the drive motor is activated, rotating the rotating shaft. Simultaneously, the control valve opens, allowing hot water to enter the rotating shaft through the hot water pipe and spray outwards through the cleaning port. The rotating shaft, in turn, drives the cleaning port to rotate, rinsing the inner wall of the hopper with the sprayed hot water. After rinsing, the control valve and drive motor are closed, and the cleaning port is then closed via a control mechanism, thus preventing water from entering during the subsequent packaging process of the paste. In the process, the paste enters the rotating shaft through the cleaning hole, affecting the subsequent cleaning of the hopper. By setting up a rotating shaft and cleaning holes, hot water sprayed from the cleaning holes during the rotation of the rotating shaft can rinse various parts of the inner wall of the hopper, thereby achieving automatic cleaning of the hopper. Compared with manual cleaning, this can improve the cleaning efficiency of the hopper. At the same time, by setting up a cover plate, the cover plate can be removed when it is necessary to add paste. The cover plate prevents hot water from spraying out from the opening at the top of the hopper during the cleaning process, and also prevents the paste from splashing out from the top of the hopper during the packaging and mixing process.

[0016] 2. By setting up support rings and adjusting rings, when the hopper needs cleaning, the worker manually rotates the adjusting ring, causing the hot water pipe to move the cleaning pipe horizontally towards the hopper until the locking block abuts against the end of the locking groove. At this point, the cleaning hole and the control hole are connected. Then, the control valve and drive motor are opened, and hot water sprays out from the cleaning hole through the hot water pipe and the cleaning pipe. The drive motor drives the rotating shaft and the cleaning hole to rotate, and the rotating shaft drives the cleaning pipe to rotate synchronously through the locking block and the locking groove (during this process, the end of the cleaning pipe rotates around the hot water pipe). This allows the hot water sprayed from the cleaning hole to rinse various parts of the inner wall of the hopper. After rinsing is completed, the control valve and drive motor are closed, and the adjusting ring is rotated again, causing the hot water pipe to move the cleaning pipe away from the hopper until the end of the locking block moves to the end of the locking groove away from the hopper. At this point, the outer wall of the cleaning pipe is in contact with the cleaning hole, making the cleaning hole closed. Therefore, by setting up support rings and adjusting rings, workers can easily move the cleaning pipe by rotating the adjusting ring, making the operation simple and convenient.

[0023] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] This utility model provides a hopper for a paste packaging machine, such as... Figures 1 to 4As shown, the device includes a hopper 1, a discharge pipe 2 connected to the bottom of the hopper 1, and a hollow tubular rotating shaft 3 rotatably mounted on the hopper 1 in a horizontal direction. A cover plate 15 is fitted on the top of the hopper 1, and a vent hole 16 is provided on the cover plate 15. A drive motor 4 for driving the rotating shaft 3 is provided on the hopper 1. Several stirring rods 5 are evenly arranged on the rotating shaft 3. The end of the rotating shaft 3 away from the drive motor 4 passes through the hopper 1. A hot water pipe 6 is rotatably mounted on the end of the rotating shaft 3 away from the drive motor 4. A control valve 7 is provided on the hot water pipe 6. Several cleaning holes 8 are evenly arranged on the rotating shaft 3. An adjustment mechanism 9 for controlling the opening and closing of the cleaning holes 8 is provided on the hopper 1.

[0025] Furthermore, the adjustment mechanism 9 includes a cleaning tube 9a that is movably attached to the inner wall of the rotating shaft 3 and a plurality of control holes 9b evenly opened on the outer wall of the cleaning tube 9a, each corresponding to a cleaning hole 8. The cross-sectional area of ​​the control holes 9b is larger than the cross-sectional area of ​​the cleaning holes 8. The rotating shaft 3 is provided with a synchronization mechanism 10 for driving the cleaning tube 9a to rotate synchronously. One end of the cleaning tube 9a is at a set distance from the inner wall of the hopper 1, and the other end of the cleaning tube 9a is rotatably connected to the hot water pipe 6. The end of the rotating shaft 3 away from the drive motor 4 is at a set distance from the hot water pipe 6. The hopper 1 is provided with a translation mechanism 11 for pushing the cleaning tube 9a to move along the inner wall of the rotating shaft 3. The translation mechanism 11 can push the outer wall of the cleaning tube 9a to fit against the cleaning hole 8.

[0026] Furthermore, the synchronization mechanism 10 includes several elongated slots 10a located at the end of the rotating shaft 3 away from the drive motor 4, and several locking blocks 10b disposed on the outer wall of the cleaning tube 9a, which cooperate with the slots 10a one by one. When the control hole 9b is in communication with the adjacent cleaning hole 8, the end of the locking block 10b is engaged with the slot 10a. When the outer wall of the cleaning tube 9a is in contact with the cleaning hole 8, the end of the locking block 10b abuts against the end of the slot 10a near the drive motor 4.

[0027] Furthermore, the translation mechanism 11 includes a plurality of support rods 11a arranged horizontally on the hopper 1 and a support ring 11b arranged vertically on the plurality of support rods 11a. The hot water pipe 6 moves through the support ring 11b. A translation thread 12 is provided on the outer wall of the end of the hot water pipe 6 near the cleaning pipe 9a. An adjustment ring 13 that cooperates with the translation thread 12 is rotatably provided on the support ring 11b.

[0028] Furthermore, a limiting ring 14 is provided between several of the support rods 11a. The hot water pipe 6 moves through the limiting ring 14. When the end of the locking block 10b abuts against the limiting ring 14, the other end of the locking block 10b engages with the slot 10a, and the control hole 9b is in communication with the cleaning hole 8.

[0029] Furthermore, a lifting handle 17 is provided on the top of the cover plate 15.

[0030] Furthermore, the hopper 1 comprises, from bottom to top, a first hopper body 1a with a semi-circular longitudinal section and a second hopper body 1b with a rectangular longitudinal section, and the end of the stirring rod 5 is movably attached to the inner wall of the first hopper body 1a.

[0031] Furthermore, a scraper 18 with a circular arc cross-section is provided between several of the stirring rods 5, and the scraper 18 can be movably attached to the inner wall of the first hopper 1a.

[0032] Furthermore, the outer wall of the adjusting ring 13 is evenly provided with a plurality of rotating handles 19.

[0033] When the hopper needs cleaning, the worker first manually rotates the handle 19 to rotate the adjusting ring 13. The adjusting ring 13 engages with the translational thread 12 of the hot water pipe 6, causing the hot water pipe 6 to move the cleaning pipe 9a horizontally towards the hopper 1. (It should be noted that the hot water pipe 6 is connected to the hot water pump via a corrugated pipe, which can extend and retract within a certain range, allowing the hot water pipe 6 to move the cleaning pipe 9a.) This continues until the locking block 10b abuts against the end of the locking groove 10a. At this point, the cleaning hole 8 and the control hole 9b are connected. Then, the control valve 7 and the drive motor 4 are opened, and hot water is sprayed from the cleaning hole 8 through the hot water pipe 6 and the cleaning pipe 9a. The drive motor 4 drives the rotating shaft 3 and the cleaning hole 8 to rotate. The rotating shaft 3, through the locking block 10b and the locking groove 10a, drives the cleaning pipe 9a to rotate synchronously (during this process, the end of the cleaning pipe 9a rotates around the hot water pipe 6), causing the hot water sprayed from the cleaning hole 8 to impact the inner wall of the hopper 1. The cleaning process involves rinsing various parts of the hopper 1. After rinsing, the control valve 7 and drive motor 4 are closed, and the adjusting ring 13 is rotated. This causes the hot water pipe 6 to move the cleaning pipe 9a away from the hopper 1 until the end of the locking block 10b moves to the end of the locking groove 10a away from the hopper 1. At this point, the outer wall of the cleaning pipe 9a is in contact with the cleaning hole 8, making the cleaning hole 8 closed. By setting the rotating shaft 3 and the cleaning hole 8, the hot water sprayed from the cleaning hole 8 can rinse various parts of the inner wall of the hopper 1 during the rotation of the rotating shaft 3, thereby achieving automatic cleaning of the hopper 1. Compared with manual cleaning, this improves the cleaning efficiency of the hopper 1. At the same time, by setting the cover plate 15, the cover plate 15 can be removed when the paste needs to be added. The cover plate 15 prevents hot water from spraying out from the opening at the top of the hopper 1 during the cleaning process and also prevents the paste from splashing out from the top of the hopper 1 during the packaging and stirring process.

[0034] By setting up a control hole 9b and a cleaning pipe 9a, the movement of the cleaning pipe 9a can drive the movement of the control hole 9b. When the control hole 9b is in communication with the cleaning hole 8, hot water can be sprayed out from the cleaning pipe 9a through the control hole 9b and the cleaning hole 8 to clean the hopper 1. When there is a certain distance between the control hole 9b and the adjacent cleaning hole 8, the outer wall of the cleaning pipe 9a is in contact with the cleaning hole 8, so that the cleaning hole 8 is in a closed state, and the filling of the paste can be carried out normally. Therefore, by setting up a control hole 9b and a cleaning pipe 9a, the opening and closing of the cleaning hole 8 can be controlled by the movement of the cleaning pipe 9a, preventing the paste from entering the cleaning hole 8 during the filling process.

[0035] By setting up support ring 11b, adjustment ring 13, etc., workers can easily move the cleaning pipe 9a by rotating the adjustment ring 13, making the operation simple and convenient.

[0036] By setting the slot 10a, the block 10b, etc., the rotating shaft 3 drives the cleaning pipe 9a to rotate around the hot water pipe 6 through the slot 10a and the block 10b during rotation, so that the control hole 9b and the cleaning hole 8 are in a state of synchronous movement, thereby ensuring that the cleaning pipe 9a can control the opening and closing of the cleaning hole 8.

[0037] By setting the limiting ring 14, the locking block 10b can be limited to ensure that the end of the locking block 10b can always be engaged in the slot 10a, avoiding excessive rotation of the adjusting ring 13 which would cause the locking block 10b to separate from the slot 10a and affect subsequent cleaning operations.

[0038] By setting the scraper 18, the stirring effect of the stirring rod 5 on the paste can be improved. It can also improve the cleaning effect of the hopper 1 by scraping the inner wall of the hopper 1 during cleaning, thereby reducing the cleaning time and improving the cleaning efficiency.

[0039] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0040] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
