Description

Technical Field

[0001] This utility model relates to the field of filling, specifically a high-precision automatic filling device. Background Technology

[0002] A filling device is an industrial packaging equipment used to fill liquids, emulsions, pastes, powders, granules, or other substances into containers (such as bottles, cans, bags, or tubes). It is widely used in the food, beverage, pharmaceutical, cosmetic, chemical, and other manufacturing industries. Based on the material properties and degree of automation, filling devices can be divided into different types, such as liquid filling machines, paste filling machines, powder filling machines, granule filling machines, as well as semi-automatic and fully automatic filling production lines. The "High-Precision Automatic Filling Device" disclosed in application number "CN115924824A" is also an increasingly mature technology. This high-precision automatic filling device, through the setting of a quantitative filling mechanism, utilizes the drive of hydraulic components to realize the material storage operation of the storage cylinder, and then, through the synchronous drive of the transmission components, realizes the completion of material storage in the storage cylinder. The control roller's switching operation in the control groove enables subsequent material feeding, facilitating the integrated operation of quantitative material storage and feeding during filling. This improves filling efficiency and accuracy, and eliminates the need for manual operation, achieving integrated mechanical operation. However, this filling device has the following drawbacks: While the storage cylinder and hydraulic components facilitate quantitative feeding, the uniformity and accuracy of this feeding need improvement. Therefore, it is necessary to provide a filling device that improves feeding uniformity and accuracy. Furthermore, the device does not allow for height adjustment during filling, potentially leading to spillage of powder materials. Therefore, a filling device that allows for height adjustment and prevents spillage is required. Utility Model Content

[0003] The present invention provides a high-precision automatic filling device, which aims to solve the problems of existing filling devices being inconvenient for precise and uniform quantitative feeding and for height adjustment.

[0004] To achieve the above objectives, this utility model provides a high-precision automatic filling device, including a filling component and a lifting mechanism;

[0005] The filling assembly includes a storage cylinder, a filling cylinder is fixedly connected to the lower end of the storage cylinder, a filling head is detachably installed at the lower end of the filling cylinder, a spiral conveying roller is rotatably connected inside the filling cylinder, a first bevel gear is fixedly connected to the upper end of the spiral conveying roller, a first motor is installed on one side of the storage cylinder, a second bevel gear is connected to the output end of the first motor, and the second bevel gear and the first bevel gear are meshed together.

[0006] A lifting mechanism includes a lifting plate. Several gravity sensors are detachably mounted on the upper end of the lifting plate. A receiving plate is mounted on the upper end of the several gravity sensors. A hopper is placed on the upper end of the receiving plate. A toothed plate is detachably mounted on the lower end of the lifting plate. A second motor is mounted on the lower end of the lifting plate. A transmission gear is fixedly connected to the output end of the second motor. The transmission gear and the toothed plate are meshed together.

[0007] As a preferred embodiment of this utility model, the inner wall of the storage cylinder is provided with limiting grooves on both sides, and the upper end of the spiral conveying roller is connected to a strip frame, both ends of which are engaged inside the limiting grooves.

[0008] As a preferred embodiment of this utility model, a mounting groove is provided on one side of the storage cylinder, and a bearing is installed inside the mounting groove. The output end of the first motor is rotatably connected inside the bearing.

[0009] As a preferred embodiment of this utility model, the lower end of the storage cylinder is fixedly connected with several support rods.

[0010] As a preferred embodiment of this utility model, the upper end of the lifting plate is provided with several positioning holes, and several support rods are inserted into the inside of the positioning holes. The upper end of the receiving plate is provided with a circular groove, and the loading hopper is installed inside the circular groove.

[0011] As a preferred embodiment of this utility model, the upper end of the lifting plate is provided with several insertion holes, and the lower ends of several gravity sensors are fixedly connected with insertion blocks, which are inserted into the insertion holes.

[0012] In a preferred embodiment of this utility model, a connecting rod is fixedly connected to the lower end of the lifting plate, and a connecting groove is provided at the upper end of the toothed plate, with the connecting rod inserted into the connecting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When performing powder and granular material filling operations, the powder and granular material is first stored in the storage cylinder. Then, the first motor is started to drive the second bevel gear to rotate, thereby driving the first bevel gear and its lower spiral conveying roller to rotate inside the filling cylinder. This allows the powder and granular material to be evenly conveyed into the filling hopper through the filling cylinder. When the filling hopper reaches the preset weight, the gravity sensor sends a signal and controls the first motor to stop. Compared with the filling device in the existing technology "a high-precision automatic filling device", this utility model, through the above-mentioned structure, can facilitate the uniform feeding of powder and granular material and improve the quantitative feeding accuracy, thereby enhancing the practicality of the filling device.

[0015] 2. Before the filling operation, the second motor is started and the transmission gear is rotated clockwise. This controls the toothed plate to rise along the transmission gear, which in turn controls the lifting plate to rise along the support rod. This allows the material hopper at the top of the receiving plate to rise and overlap with the filling cylinder, thus enabling the filling operation. Compared with the filling device in the existing technology "A High-Precision Automatic Filling Device", this utility model, through the cooperation of the above structures, facilitates the adjustment of the height of the lifting plate, avoids the spillage of powder materials, and improves the ease of use of the filling device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a high-precision automatic filling device, including a filling component 100 and a lifting mechanism 200;

[0023] The filling assembly 100 includes a storage cylinder 101, a filling cylinder 102 fixedly connected to the lower end of the storage cylinder 101, a filling head 103 detachably installed at the lower end of the filling cylinder 102, a spiral conveying roller 104 rotatably connected inside the filling cylinder 102, a first bevel gear 105 fixedly connected to the upper end of the spiral conveying roller 104, a first motor 106 installed on one side of the storage cylinder 101, a second bevel gear 107 connected to the output end of the first motor 106, and the second bevel gear 107 and the first bevel gear 105 meshing with each other.

[0024] The lifting mechanism 200 includes a lifting plate 201. Several gravity sensors 202 are detachably installed on the upper end of the lifting plate 201. A receiving plate 203 is installed on the upper end of the several gravity sensors 202. A loading hopper 204 is placed on the upper end of the receiving plate 203. A toothed plate 205 is detachably installed on the lower end of the lifting plate 201. A second motor 206 is installed on the lower end of the lifting plate 201. A transmission gear 207 is fixedly connected to the output end of the second motor 206. The transmission gear 207 and the toothed plate 205 are meshed together.

[0025] In one specific embodiment, the filling component 100, in conjunction with the lifting mechanism 200, not only facilitates uniform and precise quantitative feeding of powdered materials, thus enhancing the practicality of the filling device, but also allows for easy adjustment of the filling device height, preventing spillage of powdered materials during filling. This improves the ease of use of the filling device. In operation, the second motor 206 is first started, rotating the transmission gear 207, which controls the toothed plate 205 to rise along with the lifting plate 201. At this time, the filling head 103 moves along with the filling hopper 201. The material rises into the filling hopper 204, and then the first motor 106 is started to drive the second bevel gear 107 to rotate. This drives the first bevel gear 105 and its lower spiral conveying roller 104 to rotate inside the filling cylinder 102, thereby uniformly conveying the powder material in the storage cylinder 101 from the filling head 103 into the filling hopper 204. When the powder material reaches the preset weight, the gravity sensor 202 sends a signal and controls the first motor 106 to stop rotating, thus achieving uniform and precise quantitative feeding of the powder material, which enhances the practicality of the filling device.

[0026] Please see Figure 2 and Figure 3 Limiting grooves 111 are provided on both sides of the inner wall of the storage cylinder 101. A strip frame 112 is connected to the upper end of the spiral conveying roller 104, and both ends of the strip frame 112 are engaged inside the limiting grooves 111.

[0027] In one specific embodiment, the strip frame 112 is installed inside the limiting groove 111, which can improve the installation stability of the first bevel gear 105 and facilitate disassembly as needed.

[0028] Please see Figure 2 and Figure 3 A mounting groove 121 is provided on one side of the storage cylinder 101. A bearing 122 is installed inside the mounting groove 121, and the output end of the first motor 106 is rotatably connected to the inside of the bearing 122.

[0029] In one specific embodiment, the presence of bearing 122 can reduce the friction of the second bevel gear 107 and improve the rotational smoothness of the spiral conveying roller 104.

[0030] Please see Figure 2 and Figure 3 Several support rods 131 are fixedly connected to the lower end of the storage cylinder 101.

[0031] In one specific embodiment, the support rod 131 facilitates the improvement of the stability of the storage cylinder 101 and the lifting plate 201.

[0032] Please see Figure 4 The upper end of the lifting plate 201 is provided with several positioning holes 211, and several support rods 131 are inserted into the inside of the positioning holes 211. The upper end of the receiving plate 203 is provided with a circular groove 212, and the loading hopper 204 is installed inside the circular groove 212.

[0033] In one specific embodiment, the circular groove 212 facilitates the installation and positioning of the receiving plate 203, and the support rod 131 is inserted into the positioning hole 211. When the lifting plate 201 is raised or lowered, it can play a guiding role and improve the lifting stability of the lifting plate 201.

[0034] Please see Figure 4 The upper end of the lifting plate 201 is provided with several insertion holes 221, and the lower ends of several gravity sensors 202 are fixedly connected with insertion blocks 222, which are inserted into the insertion holes 221.

[0035] In one specific embodiment, the insertion block 222 is inserted into the insertion hole 221, which can improve the ease of installation and removal of the gravity sensor 202.

[0036] Please see Figure 4 The lower end of the lifting plate 201 is fixedly connected to a connecting rod 231, and the upper end of the toothed plate 205 is provided with a connecting groove 232, in which the connecting rod 231 is inserted.

[0037] In one specific embodiment, the connecting rod 231 is inserted into the connecting groove 232, which can improve the ease of disassembling and assembling the toothed plate 205.

[0038] Working principle: In use, the second motor 206 is started first, which drives the transmission gear 207 to rotate, thereby controlling the toothed plate 205 to rise with the lifting plate 201. At this time, the filling head 103 enters the filling hopper 204 as the filling hopper 204 rises. Then, the first motor 106 is started, which drives the second bevel gear 107 to rotate, thereby driving the first bevel gear 105 and its lower spiral conveying roller 104 to rotate inside the filling cylinder 102. This allows the powder material in the storage cylinder 101 to be evenly conveyed from the filling head 103 into the filling hopper 204. When the powder material reaches the preset weight, the gravity sensor 202 sends a signal and controls the first motor 106 to stop rotating, so as to achieve uniform and accurate quantitative feeding of powder material, thereby enhancing the practicality of the filling device.
