Description

Technical Field

[0001] This application relates to filling machines, and more particularly to a filling machine. Background Technology

[0002] A filling machine is an industrial piece of equipment used to automatically fill liquids, pastes, granules or powders into containers (such as bottles, bags, cans, etc.). It is widely used in the food, beverage, cosmetics, pharmaceutical, and chemical industries and can complete filling operations for various packaging forms such as bottling, canning, bagging, and barreling. It can greatly improve the production efficiency of manufacturers.

[0003] A current patent (publication number: CN120157075A) discloses an energy-saving filling machine, including a base plate, a feeding mechanism, a receiving mechanism, and a filling mechanism. The filling mechanism includes a storage tank, a discharge pipe, a cover, a steering cylinder, a feeding assembly, a transmission assembly, and a drive assembly. The feeding mechanism includes a conveyor and a rotating assembly. The receiving mechanism includes a receiving tray, a reciprocating sliding assembly, and a scraping assembly. Through the rotating assembly, the conveyor can only rotate a certain distance each time, so that the bottles above the conveyor can be moved sequentially to below the discharge pipe, which is conducive to continuous filling. At the same time, during the bottle movement to change bottles, the receiving tray can move to below the discharge pipe under the action of the reciprocating sliding assembly to catch the liquid remaining at the filling head, preventing the residual material from dripping directly downwards. That is, it can accurately catch the liquid remaining at the filling head during the bottle changing process, with high synchronization.

[0004] Although the device in the aforementioned comparative document solves the problem that stirring often results in a large number of air bubbles that cannot be removed and that these air bubbles enter the bottle during filling, affecting filling accuracy, the device has low filling efficiency and cannot fill multiple bottles simultaneously. To solve the above problems, a filling machine is proposed. Utility Model Content

[0005] The purpose of this application is to provide a filling machine with advantages such as high filling efficiency, which solves the problem that existing filling machines are difficult to fill multiple bottles simultaneously in actual production, resulting in low filling output per unit time and inability to meet the needs of large-scale production.

[0006] The filling machine provided in this application adopts the following technical solution: it includes a housing, the housing is provided with an operation chamber and a storage chamber, the operation chamber is provided with through holes on both sides, two baffles are provided inside the through holes, a conveying structure is provided between the two baffles, support frames are provided on both sides of the bottom of the two baffles, bottles are transported on the top of the conveying structure, a support rod is fixedly connected to the bottom of the operation chamber, a support block is provided on the surface of the support rod, a cylinder is fixedly connected to the side of the support block, a lifting frame is fixedly connected to the bottom of the cylinder, multiple filling heads are installed and connected to the bottom of the lifting frame, and a filling plug is provided at the bottom of the filling head; Two U-shaped mounting plates are installed and connected between the bottoms of the two baffles. Adjustment boxes are fixedly connected to the top of the two U-shaped mounting plates on opposite sides. A rotating shaft is tightly nested inside the adjustment box via bearings. A knob and a threaded rod are fixedly connected to both ends of the rotating shaft, respectively. A threaded cylinder is threadedly connected to the surface of the threaded rod. A movable rod is fixedly connected to the surface of the threaded cylinder. A signal generator is fixedly connected to the side of one movable rod. A signal receiver and an L-shaped connecting block are fixedly connected to the side of the other movable rod. An electric push rod is fixedly connected inside the L-shaped connecting block. A partition is fixedly connected to one end of the electric push rod. By adopting the above technical solution and setting multiple filling heads, multiple sets of bottles transported on the conveyor structure can be filled simultaneously, which can increase the filling output per unit time. When the bottle moves to the bottom of the filling head with the conveyor structure, a signal generator and a signal receiver are set up. The cooperation between the signal generator and the signal receiver can accurately detect the position of the bottle. Then, the electric push rod pushes the partition to temporarily block the subsequent bottles, which can ensure that the current batch of bottles is stably in the filling position. At the same time, turning the knob can drive the threaded rod to rotate, so that the threaded cylinder drives the movable rod to adjust the distance between the signal generator and the signal receiver, which can adapt to the detection requirements of different bottle sizes and further ensure the continuity and accuracy of the filling process.

[0007] Preferably, a contact pad is fixedly connected to the side of the partition; By adopting the above technical solution and setting a contact pad, a buffering effect can be achieved when the partition comes into contact with the bottle, thus avoiding damage to the bottle from rigid collisions.

[0008] Preferably, the adjustment box has scale lines on its side, and the knob has a pointer on its side; By adopting the above technical solution and setting the scale line and pointer in coordination, the operator can intuitively read the current spacing value through the scale line pointed to by the pointer when turning the knob to adjust the position of the signal generator and signal receiver. There is no need for repeated attempts or external measuring tools, which improves the convenience and accuracy of adjusting the detection parameters of different bottle sizes and makes the spacing adjustment process more efficient.

[0009] Preferably, a connecting bolt is fixedly connected to the top of the filling head, a strip groove is provided inside the lifting frame, the connecting bolt is slidably connected in the strip groove, and a fastening nut is threaded on the surface of the connecting bolt, with the fastening nut located at the top of the lifting frame; By adopting the above technical solution and setting a sliding fit between the connecting bolt and the strip groove, the operator can slide the connecting bolt along the strip groove according to the size requirements of different bottles, thereby moving the filling head. Once the position is determined, tightening the fastening nut at the top of the lifting frame will fix the connecting bolt in the strip groove, thus achieving quick locking of the filling head. This eliminates the need to disassemble the entire lifting frame or replace the connecting parts when adjusting the position of the filling head, greatly simplifying the position adaptation process when filling bottles of different sizes.

[0010] Preferably, two L-shaped plates are installed and connected to the sides of both baffles, and a mounting bracket is installed and connected to the top of the L-shaped plate. A sliding rod is slidably connected inside the mounting bracket, and a limit plate is fixedly connected to one end of the sliding rod. By adopting the above technical solution and by setting the sliding cooperation between the slide bar and the mounting frame, the operator can push the limiting plate to drive the slide bar to slide laterally within the mounting frame according to the diameter of the bottle, thereby adjusting the distance between the two limiting plates.

[0011] Preferably, the top of the mounting bracket is threaded with a clamping bolt, and the bottom end of the clamping bolt overlaps the surface of the slide rod; By adopting the above technical solution and setting the threaded connection between the clamping bolt and the mounting bracket, after the position of the limiting plate is adjusted, the operator can rotate the clamping bolt clockwise so that its bottom end gradually moves down and presses tightly against the surface of the sliding rod. The friction force is used to fix the sliding rod in the current position, thereby achieving stable locking of the spacing between the limiting plates. This can prevent the positioning deviation caused by the displacement of the limiting plate during the conveying process of the bottle, thereby improving the stability and accuracy of the filling operation.

[0012] Preferably, a controller is provided on the side of the housing; By adopting the above technical solution and setting up electrical connections between the controller and each execution component of the filling machine, operators can preset filling parameters, such as filling volume and conveying speed, through the touch interface on the controller.

[0013] Preferably, adjustable support feet are fixedly connected to the bottom of the housing and the bottom of the support frame; By adopting the above technical solution and setting up a fixed connection between the adjustable support feet and the box and support frame, the operator can rotate the height adjustment nuts of each adjustable support foot according to the flatness of the ground of the actual installation site to keep the bottom of the box and support frame level.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. This filling machine, by setting multiple filling heads, can simultaneously fill multiple groups of bottles transported on the conveyor structure, thereby increasing the filling output per unit time. When the bottle moves to the bottom of the filling head with the conveyor structure, a signal generator and a signal receiver are set up. The cooperation between the signal generator and the signal receiver can accurately detect the position of the bottle. Then, the electric push rod pushes the partition to temporarily block the subsequent bottles, which can ensure that the bottles of the current batch are stably in the filling position. At the same time, turning the knob can drive the threaded rod to rotate, so that the threaded cylinder drives the movable rod to adjust the distance between the signal generator and the signal receiver, adapting to the detection needs of different bottle sizes, and further ensuring the continuity and accuracy of the filling process. 2. This filling machine, by setting a sliding fit between the connecting bolt and the strip groove, allows the operator to slide the connecting bolt along the strip groove according to the size requirements of different bottles, thereby moving the filling head. Once the position is determined, tightening the fastening nut at the top of the lifting frame will fix the connecting bolt in the strip groove, thus achieving quick locking of the filling head. This eliminates the need to disassemble the entire lifting frame or replace the connecting parts when adjusting the position of the filling head, greatly simplifying the position adaptation process when filling bottles of different sizes.

[0017] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0018] Example 1: A filling machine, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The container includes a housing 1, which contains an operating chamber 102 and a storage chamber 104. The operating chamber 102 has through holes 103 on both sides. Two baffles 4 are installed inside the through holes 103. A conveying structure 402 is installed between the two baffles 4. Support frames 401 are installed on both sides of the bottom of the two baffles 4. Bottles 6 are transported on the top of the conveying structure 402. A support rod 2 is fixedly connected to the bottom of the operating chamber 102. A support block 201 is installed on the surface of the support rod 2. A cylinder 202 is fixedly connected to the side of the support block 201. A lifting frame 203 is fixedly connected to the bottom of the cylinder 202. Multiple filling heads 3 are installed and connected to the bottom of the lifting frame 203. A filling plug 301 is installed at the bottom of the filling head 3. Two U-shaped mounting plates 7 are installed and connected between the bottoms of the two baffles 4. Adjustment boxes 701 are fixedly connected to the top of the two U-shaped mounting plates 7 on opposite sides. A rotating shaft 702 is tightly nested inside the adjustment box 701 via bearings. A knob 704 and a threaded rod 703 are fixedly connected to both ends of the rotating shaft 702, respectively. A threaded cylinder 705 is threaded onto the surface of the threaded rod 703. A movable rod 706 is fixedly connected to the surface of the threaded cylinder 705. A signal generator 707 is fixedly connected to the side of one movable rod 706, and a signal receiver 708 and an L-shaped connecting block 709 are fixedly connected to the side of the other movable rod 706. An electric push rod 7010 is fixedly connected inside the L-shaped connecting block 709. A partition 7011 is fixedly connected to one end of the electric push rod 7010. By setting multiple filling heads 3, simultaneous filling can be achieved. Synchronous filling of multiple sets of bottles 6 transported on the conveyor structure 402 can increase the filling output per unit time. When the bottle 6 moves with the conveyor structure 402 to below the filling head 3, the signal generator 707 and signal receiver 708 are set up. The cooperation of the signal generator 707 and signal receiver 708 can accurately detect the position of the bottle 6. Then, the electric push rod 7010 pushes the partition 7011 to temporarily block the subsequent bottles 6, which can ensure that the current batch of bottles 6 is stably in the filling position. At the same time, turning the knob 704 can drive the threaded rod 703 to rotate, so that the threaded cylinder 705 drives the movable rod 706 to adjust the distance between the signal generator 707 and the signal receiver 708 to adapt to the detection requirements of different bottle sizes 6, and further ensure the continuity and accuracy of the filling process.

[0019] Please see Figure 5 A contact pad 7014 is fixedly connected to the side of the partition 7011. By setting the contact pad 7014, it can play a buffering role when the partition 7011 comes into contact with the bottle 6, which can avoid damage to the bottle 6 caused by rigid collision. The side of the adjustment box 701 is provided with a scale line 7012, and the side of the knob 704 is provided with a pointer 7013. By setting the scale line 7012 and the pointer 7013 in cooperation, when the operator rotates the knob 704 to adjust the position of the signal generator 707 and the signal receiver 708, he can intuitively read the current spacing value through the scale line 7012 pointed to by the pointer 7013. There is no need for repeated attempts or external measuring tools, which improves the convenience and accuracy of adjusting the detection parameters of bottles 6 of different specifications, and makes the spacing adjustment process more efficient.

[0020] Please see Figure 3A connecting bolt 302 is fixedly connected to the top of the filling head 3. A strip groove 204 is opened inside the lifting frame 203. The connecting bolt 302 is slidably connected in the strip groove 204. A fastening nut 303 is threaded on the surface of the connecting bolt 302. The fastening nut 303 is located at the top of the lifting frame 203. By setting the sliding engagement between the connecting bolt 302 and the strip groove 204, the operator can slide the connecting bolt 302 along the strip groove 204 according to the size requirements of different bottles 6, thereby moving the filling head 3. When the position is determined, tighten the fastening nut 303 at the top of the lifting frame 203 to fix the connecting bolt 302 in the strip groove 204. This allows for quick locking of the filling head 3, so that the position adjustment of the filling head 3 does not require disassembling the entire lifting frame 203 or replacing the connecting parts, greatly simplifying the position adaptation process when filling bottles of different sizes 6.

[0021] Please see Figure 6 Two L-shaped plates 403 are installed on the sides of both baffles 4. A mounting bracket 404 is installed on the top of each L-shaped plate 403. A sliding rod 405 is slidably connected inside the mounting bracket 404. One end of the sliding rod 405 is fixedly connected to a limiting plate 407. By setting the sliding engagement between the sliding rod 405 and the mounting bracket 404, the operator can push the limiting plate 407 to cause the sliding rod 405 to slide laterally within the mounting bracket 404 according to the diameter of the bottle 6, thereby adjusting the distance between the two limiting plates 407. A clamping bolt 40 is threadedly connected to the top of the mounting bracket 404. 6. The bottom end of the clamping bolt 406 overlaps the surface of the slide bar 405. By setting the threaded connection between the clamping bolt 406 and the mounting bracket 404, after the position of the limiting plate 407 is adjusted, the operator can rotate the clamping bolt 406 clockwise so that its bottom end gradually moves down and presses tightly against the surface of the slide bar 405. The friction force is used to fix the slide bar 405 in the current position, thereby achieving stable locking of the spacing of the limiting plate 407. This can prevent the bottle body 6 from being misaligned due to the displacement of the limiting plate 407 during the conveying process, thereby improving the stability and accuracy of the filling operation.

[0022] Please see Figure 1 and Figure 2 A controller 101 is installed on the side of the housing 1. The controller 101 is electrically connected to each of the execution components of the filling machine. The operator can preset filling parameters, such as filling volume and conveying speed, through the touch interface on the controller 101. Adjustable support feet 5 are fixedly connected to the bottom of the housing 1 and the bottom of the support frame 401. By fixing the adjustable support feet 5 to the housing 1 and the support frame 401, the operator can rotate the height adjustment nuts of each adjustable support foot 5 according to the flatness of the ground of the actual installation site to keep the bottom of the housing 1 and the support frame 401 in a horizontal state.

[0023] It should be noted that the filling head 3 is connected to the external liquid supply system through a delivery pipe made of corrosion-resistant material.

[0024] The implementation principle of this application embodiment is as follows: When in use, the operator first inputs the required filling volume, the running speed of the conveying structure 402 and other parameters through the touch interface of the controller 101; Next, according to the specifications of the bottle 6 to be filled, rotate the knob 704 on the side of the adjustment box 701 on the U-shaped mounting plate 7. The knob 704 drives the rotating shaft 702 and the threaded rod 703 to rotate, which can cause the threaded cylinder 705 to move the movable rod 706, thereby adjusting the position of the signal generator 707 and the signal receiver 708. Then push the slide bar 405 on the mounting bracket 404 to move the limiting plate 407 to the appropriate position, rotate the clamping bolt 406 to fix the slide bar 405, and complete the adjustment of the spacing of the limiting plate 407; If the ground at the installation site is uneven, the adjustable support feet 5 at the bottom of the box 1 and the support frame 401 can be rotated to keep the equipment level. After preparation, bottle 6 is placed on conveyor structure 402 and the equipment is started. Conveyor structure 402 moves bottle 6 below filling head 3. When bottle 6 reaches between signal generator 707 and signal receiver 708, the signal is blocked. After receiving the signal, controller 101 controls electric push rod 7010 to push partition 7011 out to block subsequent bottles 6. At the same time, cylinder 202 drives lifting frame 203 to descend, so that filling plug 301 is inserted into the bottle mouth of bottle 6. Filling head 3 begins quantitative filling. After filling is completed, cylinder 202 drives lifting frame 203 to rise and reset. Electric push rod 7010 retracts and drives partition 7011 to retract. Conveyor structure 402 transports the filled bottle 6 out, and subsequent bottles 6 continue to enter the filling station. This cycle is repeated to achieve continuous filling operation.
