Description

Technical Field

[0001] The present invention relates to the technical field of chemical product bottling, and in particular to an automatic weighing and bottling device for chemical products. Background Art

[0002] Chemical products refer to various chemicals manufactured through chemical reactions or physical changes, including chemical raw materials, intermediates, finished products, and by-products, etc. These products are widely used in multiple fields such as medicine, agriculture, energy, construction, electronics, automobiles, aerospace, etc., and are an important part of modern industry.

[0003] After retrieval, a Chinese patent with the publication number CN118062338A discloses an automatic weighing and bottling device for chemical products, including a conveying device, a raw material storage module, a weighing frame, a pre-storage tank, and an error compensation module. Two groups of adjusting modules are symmetrically arranged front and back on the inner side wall of the conveying device. A filling bottle is arranged on the inner bottom wall of the conveying device. The raw material storage module is installed above the conveying device through support columns. A pre-distribution module is arranged on the inner side wall of the raw material storage module. A pre-weighing module is arranged below the pre-distribution module on the inner side wall of the raw material storage module. The weighing frame is installed on the front and back sides in the middle of the conveying device. The pre-storage tank is installed at the end of the weighing frame. The error compensation module is fixedly connected to the upper surface of the conveying device through a mounting frame, and has the beneficial effects of accurate weighing, compensating for errors, and preventing raw materials from escaping into the air. However, when this technical solution is actually used, there are still the following defects:

[0004] When bottling chemical products, especially powder products, after being added to the packaging bottle, during the movement of the packaging bottle along with the conveying device, the powder in the bottle may float into the air. This will not only cause the actual net content of the powder in the packaging bottle to be lower than the expected standard, affecting the quality of the product and the consumer experience, but also may have an adverse impact on the air quality in the workshop, increasing the concentration of dust particles in the air, and may pose a threat to the respiratory health of the staff in the long run.

[0075] 1. For this automatic weighing and bottling device for chemical products, by setting the conveyor belt and the linkage component, through the cooperation of the conveyor belt and the linkage component, the entire bottling process realizes efficient and continuous operation. As the core component for material transportation, the conveyor belt has a stable running speed and accurate positioning ability, ensuring that the packaging bottles can enter each process in sequence and orderly according to the preset trajectory and speed. The linkage component, as the key for driving and control, realizes the connection between various components such as the conveyor belt and the feeding component through precise transmission and coordination, not only improving production efficiency, reducing labor costs, but also ensuring the reliability and stability of the entire bottling process.

[0076] 2. For this automatic weighing and bottling device for chemical products, by setting the top plate and the guiding component, the setting of the top plate and the guiding component provides key guarantees for the bottling process. The top plate covers above the conveyor belt, forming a relatively enclosed space, effectively preventing powder chemical products from floating out due to factors such as wind force and vibration during the bottling and transportation processes, ensuring the cleanliness of the production environment and the hygiene of the products. At the same time, the guiding component ensures that the packaging bottles always maintain the correct direction and position during transportation through precise guidance and positioning, improving the bottling accuracy and product quality.

[0077] 3. The automatic weighing and bottling device for this chemical product, by setting the feeding component and the connecting component, when the packaging bottle moves below the feeding port, the feeding component and the connecting component cooperate to accurately inject the chemical product into the packaging bottle, ensuring that the amount of chemical product in each packaging bottle is consistent, improving the qualified rate of the product. Driven by the driving motor, the turntable rotates 180° at a time, successively sending the chemical product in the storage barrel into the material placing sleeve and the sealing sleeve, and then filling through the feeding pipe. This not only realizes the automatic conveying and distribution of the chemical product, but also improves the filling efficiency. At the same time, by rotating the threaded sleeve, the sliding sleeve and the turntable can be driven to slide along the support rod, thereby adjusting the overall length of the material placing sleeve and the sealing sleeve to adapt to packaging bottles of different capacities.

[0078] 4. The automatic weighing and bottling device for this chemical product, by setting the detection mechanism, weighing structure and electric push rod, provides a strong guarantee for product quality control and automatic sorting. The weighing structure, through high-precision sensors and data processing systems, can accurately and quickly detect the weight of each packaging bottle. When the detected weight does not meet the standard, the electric push rod will be immediately triggered to push the unqualified packaging bottle out of the production line, realizing the timely and accurate sorting of unqualified products. This not only improves the product quality and qualified rate, but also reduces the cost and error of manual sorting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0091] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0092] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0093] As shown Figures 1 to 9 in the figure, an automatic weighing and bottling device for chemical products includes a frame 1; a conveyor belt 2 disposed inside the frame 1; a top plate 3 disposed directly above the conveyor belt 2, and a feeding port is provided at the center of the top surface of the top plate 3; a connecting component disposed at the feeding port position on the top plate 3; a connecting plate 5 fixedly installed on the side surface of the frame 1; a support rod 6 rotatably installed on the top surface of the connecting plate 5; a feeding component disposed at the top end of the support rod 6; a storage bucket 8 disposed above the feeding component; a linkage component disposed at one end of the bottom surface of the frame 1; a guiding component disposed at the bottom surface of the top plate 3; a fixing frame 12 fixedly installed at the discharging end of the frame 1; a detection mechanism disposed at the discharging end of the frame 1;

[0094] First of all, packaging bottles can be placed on the conveyor belt 2 in sequence, and the linkage component can be activated to drive the conveyor belt 2, so that the packaging bottles are conveyed through the conveyor belt 2. During the conveying process of the packaging bottles, the packaging bottles can be guided through the top plate 3 and the guiding component, so that the packaging bottles can be filled through the feeding port. The chemical products to be added can be stored in the storage bucket 8. When the packaging bottle moves to directly below the feeding port along with the conveyor belt 2, the packaging bottle can be accurately bottled through the cooperation of the feeding component and the connecting component. After the chemical products in the packaging bottle are bottled, they can be continuously conveyed through the conveyor belt 2, and the top plate 3 can cover the bottle mouth of the packaging bottle to prevent powder chemical products from floating out. When the packaging bottle is conveyed to the end of the frame 1, the packaging bottle can be weighed and detected through the detection mechanism, and the packaging bottles with qualified weights can be separated from the unqualified ones. The working principle and connection method of the storage bucket 8 are mature existing technologies and will not be elaborated here.

[0095] As shown Figure 3 in Figure 4 and Figure 8 the figure, the connecting component includes: a feeding pipe 41 fixedly installed directly above the top plate 3 through a bracket, and the feeding pipe 41 is coaxially arranged with the feeding port; an insertion pipe 42 slidably installed on the inner side wall of the feeding port; a connecting seat 43 fixedly installed at the top end of the insertion pipe 42; a first spring 44 disposed between the bottom surface of the connecting seat 43 and the top surface of the top plate 3; a lifting pipe 45 slidably sleeved on the outer surface of the bottom of the feeding pipe 41; a connecting groove 46 opened on the top surface of the connecting seat 43, and the connecting groove 46 is adapted to the lifting pipe 45;

[0096] When the packaging bottle moves to the position directly below the feeding port along the conveyor belt 2, the feeding pipe 41 is in a fixed state. The lifting pipe 45 can slide along the feeding pipe 41 under the action of the linkage assembly. The bottom end of the lifting pipe 45 can always be located in the connecting groove 46 on the top surface of the connecting seat 43 to maintain sealing. When the lifting pipe 45 moves upward, the insertion pipe 42 can move upward along the feeding port under the action of the first spring 44. When the lifting pipe 45 moves downward, the first spring 44 can be compressed, causing the connecting seat 43 and the insertion pipe 42 to move downward along the feeding port, so that the insertion pipe 42 is inserted into the bottle mouth for feeding. When the lifting pipe 45 is fixed, the connecting seat 43 can be pulled downward to separate the connecting groove 46 from the lifting pipe 45, and the inside of the lifting pipe 45 can be cleaned, which is more convenient to use.

[0097] As Figure 2 , Figure 4 , Figure 5 shown, the feeding assembly includes: two connecting frames 71, symmetrically and fixedly installed on the outer wall of the support rod 6; two sealing sleeves 72, respectively fixedly installed at one end of the two connecting frames 71 away from the support rod 6, and the inner diameter of the sealing sleeve 72 is the same as the inner diameter of the material port; a sliding sleeve 73, slidably sleeved on the top end of the support rod 6 through a chute and a slider; a first threaded sleeve 74, threadedly sleeved on the outer wall of the support rod 6, and the first threaded sleeve 74 is rotatably connected to the sliding sleeve 73; a turntable 75, fixedly installed on the top surface of the sliding sleeve 73, and the discharge end of the storage barrel 8 is in contact with the top surface of the turntable 75; two material placing sleeves 76, symmetrically penetrating through the bottom surface of the turntable 75, and the material placing sleeve 76 is slidably connected to the inner wall of the sealing sleeve 72; two sealing covers 77, respectively rotatably installed at the bottom surface of the two sealing sleeves 72 through a rotating shaft and a torsion spring; a sealing rubber ring 78, fixedly installed on the top surface of the feeding pipe 41 at a position on the side of the material port;

[0098] Under the driving action of the linkage component, when the packaging bottle is conveyed to the position directly below the feeding port, the lifting pipe 45 can drive the insertion pipe 42 to insert into the bottle mouth of the packaging bottle. The chemical products in the material placing sleeve 76 and the sealing sleeve 72 can enter the packaging bottle through the feeding pipe 41, the lifting pipe 45 and the insertion pipe 42 under the action of gravity to achieve bottling. As the packaging bottle continues to be filled, the turntable 75 can rotate 180° once. When the material placing sleeve 76 rotates to the position directly below the storage barrel 8 during the rotation of the turntable 75, the chemical products in the storage barrel 8 can enter the material placing sleeve 76 and the sealing sleeve 72. When the other sealing sleeve 72 rotates to the position of the feeding pipe 41, the sealing cover plate 77 at the bottom of the sealing sleeve 72 can rotate under the action of the sealing rubber ring 78, so that the bottom of the sealing sleeve 72 is opened to fit the top material port of the feeding pipe 41, and the transmission of materials can be realized. As the turntable 75 rotates again, when the sealing cover plate 77 is separated from the sealing rubber ring 78, the sealing cover plate 77 can be reversely reset under the action of the torsion spring to seal and cover the bottom of the sealing sleeve 72, and the feeding and material conveying can be continued. When bottling packaging bottles with different capacities, the capacities in the material placing sleeve 76 and the sealing sleeve 72 can be adjusted. When adjusting, the first threaded sleeve 74 can be rotated. Since the sliding sleeve 73 is slidably connected to the support rod 6 through the chute and the slider, and the first threaded sleeve 74 is screwed to the support rod 6, when the first threaded sleeve 74 rotates, it can drive the sliding sleeve 73 and the turntable 75 to slide along the support rod 6, so as to adjust the overall length of the sealing sleeve 72 and the material placing sleeve 76, and further realize the adjustment of the internal capacity.

[0099] As Figure 1 , Figure 6 shown, the linkage component includes: a transmission plate 91, which is rotatably installed on the side of the frame 1 through a rotating rod, and the rotating rod passes through the frame 1 and is fixedly connected to the driving roller of the conveyor belt 2; four arc-shaped openings 92, which are opened at the four side positions of the transmission plate 91; four transmission openings 93, which are opened at the four corner positions of the transmission plate 91; a driving motor 94, which is fixedly installed on the side of the frame 1 through a mounting bracket; a transmission disc 95, which is fixedly installed at the output end of the driving motor 94, and the transmission disc 95 corresponds to the arc-shaped opening 92; a relief opening 96, which is opened on the outer wall of the transmission disc 95; an insertion rod 97, which is fixedly installed on the side of the transmission disc 95 through a mounting plate, the insertion rod 97 is located at the relief opening 96, and the insertion rod 97 is adapted to the transmission opening 93; a power distribution mechanism, which is arranged on the bottom surface of the frame 1;

[0100] When the driving motor 94 is turned on, it can drive the transmission disk 95 to rotate. The outer wall of the transmission disk 95 except the clearance opening 96 can rotate in the arc opening 92 on the transmission plate 91, and the transmission plate 91 cannot rotate at this time. When the insertion rod 97 in the clearance opening 96 rotates to be inserted into the transmission opening 93, the transmission plate 91 can be driven to rotate through the insertion rod 97 and the transmission opening 93, thereby realizing intermittent driving of the conveyor belt 2.

[0101] like Figure 1 , Figure 6 As shown, the transfer mechanism includes: a connecting rod 98, which is rotatably mounted on one end of the bottom surface of the frame 1, and one end of the connecting rod 98 is fixedly connected to the transmission plate 95; a cam 99, which is fixedly mounted on the end of the connecting rod 98 away from the transmission plate 95; a cam 910, which is fixedly mounted on the side of the cam 99; a connecting rod 911, which is vertically slidably mounted on the side of the frame 1 through a support frame, one end of the connecting rod 911 is located directly above the cam 99, and the other end of the connecting rod 911 is fixedly connected to the lifting tube 45; a spring 912, which is sleeved on the outer wall of the connecting rod 911, and the two ends of the spring 912 are respectively fixedly connected to the support frame and the connecting rod 911; a transmission mechanism is arranged between the cam 910 and the support rod 6;

[0102] When the transmission plate 95 rotates, the cam 1 99 and the cam 2 910 can be driven to rotate synchronously through the connecting rod 98. When the cam 1 99 rotates, the connecting rod 911 can be pushed, thereby driving the lifting tube 45 to slide upward. As the cam 1 99 continues to rotate, under the action of the spring 2 912, the connecting rod 911 can slide downward and reset, thereby driving the lifting tube 45 to move downward.

[0103] like Figure 1 , Figure 7 As shown, the transmission mechanism includes: a one-way bearing 101, which is sleeved on the outer wall of the support rod 6; a transmission gear 102, which is sleeved on the outer wall of the one-way bearing 101; a transmission shaft 103, which is horizontally slidably mounted on the top surface of the connecting plate 5 through a support frame, and the transmission shaft 103 and the connecting rod 911 are rotatably mounted with a rotating wheel at one end close to the cam 2 910 and the cam 1 99; a rack 104, which is fixedly mounted on one end of the transmission shaft 103, and the rack 104 is meshed with the transmission gear 102; a spring 3 105, which is sleeved on the transmission shaft 103, and the two ends of the spring 3 105 are respectively fixedly connected to the support frame and the transmission shaft 103;

[0104] During the rotation of the second cam 910 along with the connecting rod 98, the second cam 910 can intermittently push the transmission shaft 103. Driven by the second cam 910, the transmission shaft 103 can slide horizontally, thereby driving the rack 104 to slide to drive the transmission gear 102. This direction is the locking direction of the one-way bearing 101. Therefore, when the transmission gear 102 rotates, it can drive the support rod 6 to rotate by 180°. As the second cam 910 continues to rotate, under the action of the third spring 105, the transmission shaft 103 and the rack 104 can slide in the reverse direction. This direction is the free state of the one-way bearing 101. Therefore, it cannot drive the support rod 6 to rotate;

[0105] In summary, the overall process when the drive motor 94 is turned on is as follows: The outer wall of the transmission disc 95 rotates in the arc-shaped opening 92 on the transmission plate 91. Before the insertion rod 97 is inserted into the transmission opening 93, the first cam 99 can first drive the linkage rod 911 to move the lifting tube 45 upward, separating the insertion tube 42 from the packaging bottle. When the insertion rod 97 is inserted into the transmission opening 93, it can drive the transmission plate 91 to rotate, thereby being able to drive the conveyor belt 2 to convey the packaging bottle. At the same time, when the insertion rod 97 is in the transmission opening 93, the second cam 910 can drive the transmission shaft 103 to rotate the turntable 75 to achieve feeding. Before the sealing sleeve 72 moves to directly above the feeding tube 41, the insertion rod 97 separates from the transmission opening 93, and the packaging bottle can be located directly below the feeding port. And the lifting tube 45 moves downward, and the insertion tube 42 is inserted into the packaging bottle. Then the sealing sleeve 72 rotates to directly above the feeding tube 41 to directly perform bottling.

[0106] As Figure 2 、 Figure 9 shown, the guiding assembly includes: four guiding sleeves 111, fixedly installed at the four corner positions on the top surface of the frame 1; four lifting screws 112, respectively arranged inside the four guiding sleeves 111; four guiding grooves 113, respectively opened on the inner side walls of the four guiding sleeves 111, and a guiding block adapted to the guiding groove 113 is fixedly installed at the bottom end of the lifting screw 112; four second threaded sleeves 114, respectively rotatably installed at the top ends of the four guiding sleeves 111, and the second threaded sleeve 114 is screwed with the lifting screw 112; two support plates 115, symmetrically arranged on the bottom surface of the top plate 3; two guide plates 116, respectively fixedly installed on the bottom surfaces of the two support plates 115; two groups of openings 117, respectively opened on the side surfaces of the two guide plates 116, and each group of openings 117 is linearly arrayed on the side surface of the guide plate 116; a plurality of guiding rollers 118, respectively rotatably installed on the inner side walls of the plurality of openings 117;

[0107] When the packaging bottle is placed on the conveyor belt 2, under the conveying action of the conveyor belt 2, the packaging bottle can enter between the two guide plates 116, and the guide roller 118 in the opening 117 of the guide plate 116 can guide the packaging bottle, making the conveying of the packaging bottle more stable. At the same time, when using packaging bottles of different heights, the four second threaded sleeves 114 can be rotated synchronously. The second threaded sleeve 114 is screwed with the lifting screw 112. At the same time, the lifting screw 112 is slidably connected to the guide sleeve 111 through the guide groove 113 and the guide block. Therefore, when the second threaded sleeve 114 rotates, it can drive the lifting screw 112 to slide along the guide sleeve 111, so as to realize the adjustment of the height of the top plate 3 to adapt to the packaging bottle.

[0108] As Figure 1 , Figure 2 shown, the detection mechanism includes: a weighing structure 131, arranged at the discharge end of the frame 1, and the weighing structure 131 is connected to the conveyor belt 2; an electric push rod 132, fixedly installed on the side of the fixed frame 12; a push plate 133, fixedly installed at the telescopic end of the electric push rod 132; a discharge port 134, opened at the corresponding position of the side of the frame 1 and the fixed frame 12;

[0109] After the packaging bottle is filled, it can continue to be conveyed along with the conveyor belt 2, and its bottle mouth is covered by the top plate 3 to prevent the powder from floating out. As the conveyor belt 2 conveys, the packaging bottle can enter the weighing structure 131 for weighing to verify the weight. Qualified packaging bottles can be directly taken down by the staff, and unqualified packaging bottles can be pushed out of the discharge port 134 by the weighing structure 131 through the push plate 133 of the electric push rod 132 to be distinguished from the qualified packaging bottles for subsequent processing by the staff. The working principle and connection method of the weighing structure 131 and the electric push rod 132 are mature existing technologies and will not be elaborated here.
