Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, specifically a quantitative filling device. Background Technology

[0002] With the development of the food processing industry, the traditional method of making stuffed foods by hand has been gradually replaced by automated processing by machines. After the filling is made, a quantitative filling device is needed to accurately deliver the filling into the dough in order to achieve automated production.

[0003] Traditional filling channels often use a single fixed inner diameter design. In actual production, the particle size of fillings varies greatly among different types of food. When conveying fillings containing large particles, the fixed inner diameter channel is prone to particle jamming. If the inner diameter of the channel is too small, large particles will get stuck in the narrow part of the channel, forming a blockage point, making it difficult for subsequent fillings to be pushed forward. Manual stopping of the machine and disassembly of the channel for cleaning are required. Therefore, the traditional fixed inner diameter cannot adapt to fillings with multiple particle sizes, making it less versatile. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a quantitative filling device, which solves the problem that traditional filling channels mostly adopt a single fixed inner diameter design, and in actual production, the particle size of fillings for different types of food varies greatly, making it impossible to adapt to fillings with multiple particle sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative filling device, comprising a screw extruder, wherein a feed inlet is provided on one side of the top of the screw extruder, and an installation sleeve is connected to the end of the screw extruder away from the feed inlet. A filling cylinder is fixed to the other side of the installation sleeve, and an elastic feeding sleeve is provided inside the filling cylinder. An opening on one side of the elastic feeding sleeve is connected to the screw extruder through an installation base. An elastic isolation ring is fixed to the side of the elastic feeding sleeve away from the installation base. The elastic isolation ring is fixed at the opening inside the filling cylinder. Several support components are provided outside the elastic feeding sleeve. Each support component includes a connecting rod. One end of the connecting rod is rotatably connected to one side of the inner wall of the filling cylinder through a pin. A ball is fixedly connected to the other end of the connecting rod. The ball is fixed at the connection point between the elastic feeding sleeve and the elastic isolation ring. An adjustment component is overlapped on the side of the several connecting rods that are away from each other. The adjustment component slides through the filling cylinder.

[0006] As a further embodiment of this utility model: a storage bin is installed inside the feed inlet, and the storage bin is funnel-shaped, and a mounting base is fixed at the bottom of the screw extruder.

[0007] As a further embodiment of this utility model: the mounting sleeve is externally mounted with bolts, and the mounting sleeve is fixed to the end of the screw extruder by the bolts.

[0008] As a further embodiment of this utility model: the elastic feeding sleeve is tapered, and the large opening of the elastic feeding sleeve is fixed to one side of the inner wall of the filling cylinder, while the small opening of the elastic feeding sleeve is connected to the middle of the elastic isolation ring.

[0009] As a further embodiment of this utility model: a spring is fixedly connected to the outside of the connecting rod near the ball, and the other end of the spring is fixed to the inner wall of the filling cylinder.

[0010] As a further embodiment of this utility model: the adjusting component includes a threaded sleeve, the outside of the filling cylinder is provided with a threaded groove, and the threaded sleeve is threadedly connected to the threaded groove outside the filling cylinder.

[0011] As a further embodiment of this utility model: the threaded sleeve has a slide rail inside, and the slide rail is a ring design. The inner wall of the slide rail is slidably connected to a slider corresponding to the position of a number of support components. A pressure roller is installed on the side of the slider away from the threaded sleeve, and the pressure roller overlaps with the connecting rod.

[0012] As a further embodiment of this utility model: the outside of the filling cylinder is provided with sliding holes corresponding to the positions of several sliders, and the sliders slide through the sliding holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This quantitative filling device uses a threaded sleeve to drive several sliders and pressure rollers to move synchronously to the right. When the pressure roller moves to the right on the connecting rod, the tension of the spring causes one end of the connecting rod to move closer to the inner wall of the filling cylinder. The end of the connecting rod is fixed to the ball, causing the ball to pull the connection between the elastic feeding sleeve and the elastic isolation ring, causing deformation of the elastic feeding sleeve and the elastic isolation ring. At this time, the diameter of the right end of the elastic feeding sleeve expands. If the threaded sleeve moves to the left, the slider drives the pressure roller to move to the left on the connecting rod. Since the height of the slider does not change, the pressure roller will press down on the connecting rod during the movement, allowing the left end of the connecting rod to deflect. The right end, through the ball, drives the right opening of the elastic feeding sleeve to move closer to the center of the filling cylinder, thereby reducing the inner diameter of the opening and changing the inner diameter of the opening. This abandons the traditional design of using a single fixed inner diameter. This device can adapt to fillings of various particle sizes and has wide applicability.

[0014] 2. This quantitative filling device controls the operation of the screw extruder to uniformly convey the filling to the right. The filling enters the filling cylinder through the mounting sleeve and is then conveyed to the right through the elastic feeding sleeve inside the filling cylinder. The filling is discharged from the right side of the elastic feeding sleeve. The quantitative filling is achieved by controlling the interval of the screw extruder's operation. When changing the specifications of the filling cylinder and elastic feeding sleeve, the locking state between the mounting sleeve and the end of the screw extruder is released by loosening the bolts. Then, the filling cylinder can be removed by pulling it to the right. During installation, the mounting sleeve is inserted into the open end of the screw extruder, and the bolts are tightened to lock it. Therefore, the modular design meets the needs of using various specifications of filling and is easy to operate. Attached Figure Description

Detailed Implementation

[0016] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0017] like Figure 1-6 As shown, this utility model provides a technical solution: a quantitative filling device, including a screw extruder 1, a feed inlet 2 on one side of the top of the screw extruder 1, a storage bin 3 installed in the feed inlet 2, and the storage bin 3 is funnel-shaped, and a mounting base 4 is fixed at the bottom of the screw extruder 1. An installation sleeve 5 is connected to one end of the screw extruder 1 away from the feed inlet 2. A feeding cylinder 6 is fixed to the other side of the installation sleeve 5. An elastic feeding sleeve 8 is provided inside the feeding cylinder 6. A bolt 7 is installed on the outside of the installation sleeve 5. The installation sleeve 5 is fixed to the end of the screw extruder 1 by the bolt 7. The locking state between the installation sleeve 5 and the end of the screw extruder 1 is released by loosening the bolt 7. Then, the feeding cylinder 6 can be removed by pulling it to the right. When installing, the installation sleeve 5 is inserted into the open end of the screw extruder 1, and the bolt 7 is tightened to lock it. This makes it convenient to change the specifications of the feeding cylinder 6 and the elastic feeding sleeve 8. The opening on one side of the elastic feeding sleeve 8 is connected to the screw extruder 1 through the mounting base 4. An elastic isolation ring 9 is fixed on the side of the elastic feeding sleeve 8 away from the mounting base 4. The elastic isolation ring 9 is fixed at the opening inside the filling cylinder 6. The elastic feeding sleeve 8 is tapered, and the large opening of the elastic feeding sleeve 8 is fixed to one side of the inner wall of the filling cylinder 6. The small opening of the elastic feeding sleeve 8 is connected to the middle of the elastic isolation ring 9. Because the elastic feeding sleeve 8 is tapered and the opening is larger on the left and smaller on the right, when the filling is discharged from the right side of the elastic feeding sleeve 8, the size of the filling particles is much smaller than the diameter of the filling cylinder 6. The elastic feeding sleeve 8 is provided with several support components 10 on its outside. Each support component 10 includes a connecting rod 101. One end of the connecting rod 101 is rotatably connected to one side of the inner wall of the filling cylinder 6 via a pin. The other end of the connecting rod 101 is fixedly connected to a ball 102. The ball 102 is fixed inside the elastic feeding sleeve 8 at the connection point with the elastic isolation ring 9. A spring 103 is fixedly connected to the outside of the connecting rod 101 near the ball 102. The other end of the spring 103 is fixed to the inner wall of the filling cylinder 6. The tension of the spring 103 drives one end of the connecting rod 101 to move closer to the inner wall of the filling cylinder 6. The connecting rod 101 then pulls the connection point between the elastic feeding sleeve 8 and the elastic isolation ring 9 through the ball 102, causing the elastic feeding sleeve 8 and the elastic isolation ring 9 to deform. At this time, the diameter of the right end of the elastic feeding sleeve 8 expands, thereby changing the inner diameter of the opening. An adjustment component 12 is attached to one side of several connecting rods 101 that are far apart from each other. The adjustment component 12 slides through the filling cylinder 6. The adjustment component 12 includes a threaded sleeve 121. A threaded groove 13 is opened on the outside of the filling cylinder 6, and the threaded sleeve 121 is threadedly connected to the threaded groove 13 on the outside of the filling cylinder 6. A slide 122 is opened inside the threaded sleeve 121. The slide 122 is annular. The inner wall of the slide 122 is slidably connected to the sliders 123 corresponding to the positions of several support components 10. Through the cooperation between the slide 122 and the sliders 123, the threaded sleeve 121 moves during the movement. The internal slide 122 drives several sliders 123 to move to the right synchronously. The sliders 123 can slide in the slide 122 without deflection. A pressure roller 124 is installed on the side of the slider 123 away from the threaded sleeve 121. The pressure roller 124 overlaps with the connecting rod 101. When the pressure roller 124 moves to the left, it will press down on the connecting rod 101, so that the left end of the connecting rod 101 can deflect, and the right end will drive the right end opening of the elastic feeding sleeve 8 to move closer to the center of the filling cylinder 6 through the ball 102, so as to reduce the inner diameter of the right end opening of the elastic feeding sleeve 8.

[0018] Sliding holes 11 are provided on the outside of the filling cylinder 6 at the positions corresponding to several sliders 123. The sliders 123 slide through the sliding holes 11, and the sliding holes 11 limit the sliders 123, thereby improving the stability of the sliders 123 driving the pressure rollers 124 to move horizontally.

[0019] The working principle of this utility model is as follows: In use, the processed filling is added to the funnel-shaped storage bin 3, allowing the filling to enter the screw extruder 1 through the feed inlet 2. During operation, the screw extruder 1 evenly conveys the filling to the right. The filling then enters the feeding cylinder 6 through the mounting sleeve 5, and is conveyed to the right from the elastic feeding sleeve 8 within the feeding cylinder 6. Because the elastic feeding sleeve 8 has a conical design with a larger opening on the left and a smaller opening on the right, the filling particles discharged from the right side of the elastic feeding sleeve 8 are much smaller than the diameter of the feeding cylinder 6. The feed rate is achieved by controlling the interval of the screw extruder 1's working time. When adjusting the particle size of the feed, the threaded sleeve 121 is rotated in the reverse direction, causing it to move to the right outside the feed cylinder 6. Simultaneously, the threaded sleeve 121 drives several sliders 123 to move to the right synchronously through the internal slide rail 122. The sliders 123 are limited by the sliding hole 11, improving the stability of the sliders 123 driving the pressure roller 124 to move horizontally. When the pressure roller 124 is on the connecting rod 101 When the upper part moves to the right, the tension of the spring 103 causes one end of the connecting rod 101 to move closer to the inner wall of the filling cylinder 6, while the other end of the connecting rod 101 rotates on one side inside the filling cylinder 6 via a pin. Since the end of the connecting rod 101 is fixed to the ball 102, the ball 102 pulls the connection between the elastic feeding sleeve 8 and the elastic isolation ring 9, causing the elastic feeding sleeve 8 and the elastic isolation ring 9 to deform. At this time, the diameter of the right end of the elastic feeding sleeve 8 expands, thereby changing the inner diameter of the opening. When the threaded sleeve 121 moves to the left, the threaded sleeve 121 pushes multiple sliders 123 to move to the left through the slide rail 122. The sliders 123 then drive the pressure roller 124 to move to the left on the connecting rod 101. Since the height of the slider 123 does not change, the pressure roller 124 will press down on the connecting rod 101 during the movement, so that the left end of the connecting rod 101 can deflect, and the right end will drive the right end opening of the elastic feeding sleeve 8 to move closer to the center of the filling cylinder 6 through the ball 102, thereby reducing the inner diameter of the opening.
