Description

Technical Field

[0001] This invention relates to the field of yogurt filling technology, specifically to a filling device for yogurt production. Background Technology

[0002] Yogurt is a beverage made from animal milk through fermentation with lactic acid bacteria. It is mainly made from milk, which is pasteurized and then beneficial bacteria are added. After a period of fermentation, it is made into yogurt. In order to achieve automated production and improve production efficiency, yogurt filling equipment is generally used to fill yogurt.

[0003] During the yogurt filling process, empty bottles are first moved to the filling station by a conveyor. At this point, the filling head is lowered above the bottle opening or enters the bottle. Then, a measured amount of yogurt is injected into the empty bottle through the filling tube until filling is complete. After filling is finished, the filling head is moved away from the bottle opening to complete the filling process. In this process, when filling stops, some yogurt will inevitably remain at the outlet of the filling head, especially for yogurt with a high viscosity. This residual yogurt is easily stretched into threads and drips when the filling head is lifted. When the residual yogurt drips outside the bottle or onto the conveyor, it not only affects the cleanliness of the packaging but also the hygiene of the production line. Summary of the Invention

[0004] This invention proposes a filling device for yogurt production, which solves the problem in the prior art that when filling viscous yogurt, yogurt residue easily remains at the nozzle after filling. This residue can easily drip, affecting the cleanliness of the packaging and the hygiene of the production line.

[0005] The technical solution of the present invention is as follows:

[0006] A yogurt production filling device includes a filling frame and a conveying device. A hanging frame is fixedly installed on the filling frame, and a plurality of bottle holders are evenly spaced on the chain conveyor belt of the conveying device. The device also includes:

[0007] A first driving component is fixedly mounted on the hanging frame. An assembly bracket is fixedly mounted on the output end of the first driving component. The assembly bracket is horizontally arranged and has an installation groove.

[0008] A closed filling assembly is provided on the mounting groove. Each of the closed filling assemblies has a filling station at its bottom, which is used to fill yogurt into the bottles in the bottle holder and to close the filling channel after filling.

[0009] An anti-drip component is provided on the hanging frame to prevent residual yogurt at the filling channel opening of the closed filling component after filling from dripping outside the bottle;

[0010] A positioning frame is fixedly mounted on the outer shell of the conveying equipment. The positioning frame is equipped with a positioning clamping assembly, which is used to restrict the position of the yogurt bottle to be filled in the corresponding filling station before filling.

[0011] For filling yogurt into the bottle, the closed filling assembly includes:

[0012] The positioning and fixing frame is provided with a plurality of positioning and fixing frames arranged at equal intervals in the mounting groove, and each positioning and fixing frame has a mounting cylinder fixedly installed at its bottom;

[0013] An injection pipe is fixedly installed at the bottom of each of the mounting cylinders;

[0014] An intermediate tank is provided inside each of the mounting cylinders. The input end of the intermediate tank is connected to an input connector, and the output end of the intermediate tank is connected to the injection pipe through a connecting pipe.

[0015] The input end of each of the input connectors is connected to the delivery pipe;

[0016] A pipe closure mechanism is installed at the bottom of the filling pipe and is used to close the pipe opening when yogurt filling stops.

[0017] Adjustment mechanism: Each of the pipe closure mechanisms is equipped with an adjustment mechanism for controlling the opening and closing of the pipe closure mechanism.

[0018] To seal the opening of the injection tube after injection is complete, the opening closure mechanism includes:

[0019] The discharge shell is installed at the bottom of each of the injection tubes, and the output end of the injection tube is connected to the discharge shell;

[0020] Each of the discharge shells is equipped with a sealing block that rotates and seals inside.

[0021] In order to draw back the residual yogurt at the outlet of the discharge shell before the opening of the filling tube is sealed, each intermediate tank is connected to a sealing cylinder, each sealing cylinder is fixedly equipped with a second driving component, and each second driving component is fixedly equipped with a piston at its output end. The piston slides and seals against the inner wall of the sealing cylinder.

[0022] The closed filling assembly is configured such that, after filling stops and before the sealing block closes, the second drive member can first drive the piston to move within the sealing cylinder to increase the volume of the intermediate tank, thereby lifting the yogurt inside the filling tube that has not entered the bottle a certain distance toward the intermediate tank and actively sucking back the residual liquid at the outlet of the discharge shell.

[0023] To adjust the position of the sealing block within the discharge casing, the adjusting mechanism includes:

[0024] A first transmission frame and a second transmission frame are installed on each of the injection pipes, and a second transmission frame is installed on each of the discharge shells.

[0025] The transmission gear and the adjusting gear are rotatably installed inside each of the second transmission frames. The adjusting gear is fixedly connected to the sealing block. An intermediate gear is rotatably installed inside each of the second transmission frames. The intermediate gear meshes with the corresponding transmission gear and the adjusting gear respectively.

[0026] Furthermore, it also includes:

[0027] The rack and the drive gear are provided. The drive gear is rotatably mounted inside each of the first transmission frames. The drive gear is coaxially and fixedly connected to the transmission gear. The rack is slidably mounted inside each of the first transmission frames.

[0028] The third driving component is fixedly installed inside each of the mounting cylinders, and the output end of the third driving component is fixedly connected to the rack through a connecting bracket.

[0029] To prevent residual yogurt from dripping from the outlet of the outer shell, the anti-drip component includes:

[0030] A receiving frame, wherein sliding sleeves are fixedly provided at both ends of the receiving frame, and the two sliding sleeves are slidably disposed on the hanging frame;

[0031] The fourth driving component is provided on the hanging frame, and the output ends of the two fourth driving components are respectively fixedly connected to the two sliding sleeves.

[0032] To prevent the bottle from shifting during the yogurt filling process, the positioning and clamping assembly includes:

[0033] A push frame, wherein two push frames are symmetrically and slidably mounted on the positioning frame;

[0034] The fifth driving component is fixedly installed on both sides of the positioning frame, and the output ends of the fifth driving components on both sides of the positioning frame are respectively fixedly connected to the two push frames.

[0035] Furthermore, each of the two push frames is provided with a number of limit frames, and each limit frame is equipped with a fastener.

[0036] Each of the limiting frames is provided with a clamping block, and several clamping blocks on one of the pushing frames correspond one-to-one with several clamping blocks on the other pushing frame and are arranged symmetrically.

[0037] The working principle and beneficial effects of this invention are as follows:

[0038] 1. In this invention, after the yogurt filling is completed, the second drive component retracts the piston, thereby increasing the volume of the intermediate tank by adjusting the piston position inside the sealing cylinder. This causes the yogurt inside the filling tube that has not yet entered the bottle to be lifted upwards towards the intermediate tank, thereby actively sucking back the residual liquid at the outlet of the discharge shell and allowing it to enter the discharge shell. Then, the adjusting mechanism drives the sealing block to rotate to a closed state inside the discharge shell. This back-suction action first actively sucks the residual liquid at the outlet of the discharge shell into the discharge shell, and then drives the sealing block to close it, thereby avoiding the chronic leakage of residual liquid and improving the cleanliness and sealing quality of the filling process.

[0039] 2. In this invention, the fifth drive unit is activated before filling the yogurt, thereby simultaneously pushing the two push frames to move synchronously, thereby pushing the corresponding limit frame and clamping block to move, thus restricting the corresponding yogurt bottle to the center position directly below the outlet of the outer shell, preventing it from shifting due to liquid impact or equipment micro-vibration, thereby ensuring the consistency of the filling position and preventing yogurt from overflowing during filling.

[0056] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0057] like Figures 1 to 4 As shown, this embodiment proposes a yogurt production filling device, including a filling frame 1 and a conveying device 2. A hanging frame 3 is fixedly installed on the filling frame 1. Several bottle trays 4 are evenly spaced on the chain conveyor belt of the conveying device 2. It also includes a first driving component 5, a closed filling assembly, an anti-drip assembly, and a positioning frame 8. The first driving component 5 is fixedly installed on the hanging frame 3. An assembly bracket 6 is fixedly installed at the output end of the first driving component 5. The assembly bracket 6 is horizontally arranged and has an installation groove 7. Several closed filling assemblies are installed on the installation groove 7. The bottom of each closed filling assembly corresponds to a filling station, used to fill yogurt into the bottles in the bottle trays 4 and close the filling channel after filling. The closed filling assembly includes a positioning fixing frame 101, a filling pipe 103, an intermediate tank 104, a conveying pipe 107, a pipe opening closing mechanism, and a positioning mechanism. Figures 5 to 8 As shown, several adjusting and fixing brackets 101 are evenly arranged in the installation slot 7. Each adjusting and fixing bracket 101 has an installation cylinder 102 fixedly installed at its bottom. Each installation cylinder 102 has a filling pipe 103 fixedly installed at its bottom. Each installation cylinder 102 has an intermediate tank 104 inside. The input end of the intermediate tank 104 is connected to an input connector 105. The output end of the intermediate tank 104 is connected to the filling pipe 103 through a connecting pipe 106. The input end of each input connector 105 is connected to a delivery pipe 107. A pipe opening closure mechanism is installed at the bottom of the filling pipe 103 to close the pipe opening of the filling pipe 103 when the yogurt filling stops. Each pipe opening closure mechanism is equipped with an adjusting mechanism to control the opening and closing of the pipe opening closure mechanism.

[0058] By setting the positioning and fixing bracket 101, the position of the mounting cylinder 102 on the assembly bracket 6 can be adjusted to adapt to the relative position between several bottle holders 4, ensuring that when the yogurt bottles are moved to the filling position, each yogurt bottle has a corresponding filling tube 103 above its bottle mouth, which facilitates the filling process.

[0059] When yogurt needs to be filled, first connect the output end of the yogurt conveying device to the corresponding conveying pipe 107, then turn on the conveying device 2, and then place the yogurt bottles into the corresponding bottle holders 4 one by one. As the conveying device 2 runs, the conveying device 2 can be temporarily turned off when the yogurt bottles are conveyed to the filling station. At this time, there is a yogurt bottle at the bottom of each filling pipe 103. Then, remove the anti-drip component to provide operating space for the filling pipe 103 to move down. At this time, filling can begin.

[0060] When filling yogurt, the first drive unit 5 is activated, which pushes the assembly bracket 6 to move downward. This, in turn, moves all the adjusting and fixing brackets 101, thereby causing the corresponding mounting cylinder 102 and filling pipe 103 to move downward until the discharge shell 108 is moved into the bottle, reaching the filling position. At this time, the yogurt conveying device is activated to input the yogurt into the conveying pipe 107, and then into the intermediate tank 104 through the input connector 105. The yogurt entering the intermediate tank 104 enters the filling pipe 103 through the connecting pipe 106, and can then be input into the yogurt bottle through the discharge shell 108. During this process, the first drive unit 5 is slowly retracted until a certain amount of yogurt is input into the yogurt bottle.

[0061] A flow meter (not shown in the figure) is installed between the yogurt conveying device and the conveying pipe 107. The flow meter monitors the cumulative flow in real time. When the cumulative flow reaches the preset filling volume, the control system cuts off the feeding to achieve quantitative filling; or a weighing module is installed on the filling machine frame 1 to control the start and stop of feeding by the weight difference of the bottle before and after filling.

[0062] After the yogurt filling is completed, the discharge shell 108 is removed from the yogurt bottle. At the same time, before the sealing block 109 is closed, the second driving component 111 drives the piston 112 to move inside the sealing cylinder 110 to increase the volume of the intermediate tank 104, thereby drawing back the residual liquid at the outlet of the discharge shell 108. Then the adjustment mechanism can be opened to adjust the pipe closing mechanism to the closed state, thus preventing the residual liquid at the outlet of the discharge shell 108 from dripping outside the yogurt bottle.

[0063] The pipe closure mechanism includes a discharge housing 108 and a sealing block 109, such as Figures 5 to 8 As shown, each filling pipe 103 is equipped with a discharge shell 108 at its bottom. The output end of the filling pipe 103 is connected to the discharge shell 108. Each discharge shell 108 is rotatably and sealingly equipped with a sealing block 109. Each intermediate tank 104 is connected to a sealing cylinder 110. Each sealing cylinder 110 is fixedly equipped with a second driving member 111. The output end of each second driving member 111 is fixedly equipped with a piston 112. The piston 112 slides and seals with the inner wall of the sealing cylinder 110. The closed filling assembly is configured such that after filling stops and before the sealing block 109 closes, the second driving member 111 can first drive the piston 112 to move inside the sealing cylinder 110 to increase the volume of the intermediate tank 104, thereby actively sucking back the residual liquid at the outlet of the discharge shell 108.

[0064] To ensure the reliability of the rotational sealing of the sealing block 109, a food-grade conical sealing surface is provided between the sealing block 109 and the inner wall of the discharge shell 108, and a heat-resistant sealing ring is embedded therein. In addition, the inner walls of the discharge shell 108 and the filling pipe 103 are polished and have no sharp corners. When the equipment is stopped, cleaning fluid can be introduced into the conveying pipe 107 and the piston 112 can be driven to reciprocate by the second driving component 111, so that the cleaning fluid flows through the intermediate tank 104, the filling pipe 103 and the inner cavity of the discharge shell 108 to achieve in-situ cleaning.

[0065] To ensure the back suction effect, the volume change resulting from the product of the inner diameter of the sealing cylinder 110 and the stroke of the piston 112 is greater than the volume of the cavity between the outlet of the discharge housing 108 and the sealing block 109, thereby ensuring that the residual liquid at the outlet can be completely pulled back into the discharge housing 108 during back suction, and preventing the residual liquid from remaining on the outlet end face.

[0066] Since the second drive component 111 is normally in the ejected state, after the yogurt filling is completed, the discharge shell 108 is removed from the yogurt bottle. At this time, the second drive component 111 is activated first, and the piston 112 is retracted. By adjusting the position of the piston 112 inside the sealing cylinder 110, the volume of the intermediate tank 104 is increased, causing the yogurt inside the filling pipe 103 that has not entered the bottle to rise a certain distance towards the intermediate tank 104. This actively draws back the residual liquid at the outlet of the discharge shell 108, allowing it to enter the interior of the discharge shell 108. At this time, the position of the sealing block 109 inside the discharge shell 108 can be adjusted by the setting of the adjusting mechanism, so that it exits from the outlet. Figure 7 The shown on state has been adjusted to Figure 8 The closed state shown prevents residual liquid at the outlet of the discharge shell 108 from dripping onto the yogurt bottle or the conveyor belt of the conveying device 2.

[0067] The adjusting mechanism includes a first transmission frame 113, a second transmission frame 114, a transmission gear 115, and an adjusting gear 116, such as... Figures 6 to 8As shown, each injection pipe 103 is equipped with a first transmission frame 113, and each discharge shell 108 is equipped with a second transmission frame 114. Each second transmission frame 114 has a transmission gear 115 and an adjusting gear 116 rotatably mounted inside. The adjusting gear 116 is fixedly connected to the sealing block 109. Each second transmission frame 114 also has an intermediate gear 117 rotatably mounted inside. The intermediate gear 117 meshes with the corresponding transmission gear 115 and adjusting gear 116. The system also includes a rack 118, a drive gear 119, and a third drive component 120. Each first transmission frame 113 has a drive gear 119 rotatably mounted inside. The drive gear 119 is coaxially fixedly connected to the transmission gear 115. Each first transmission frame 113 has a rack 118 slidably mounted inside. Each mounting cylinder 102 has a third drive component 120 fixedly mounted inside. The output end of the third drive component 120 is fixedly connected to the rack 118 through a connecting frame 121.

[0068] When it is necessary to adjust the position of the sealing block 109 within the discharge housing 108, the third drive unit 120 is activated. The third drive unit 120 pushes the rack 118 to move through the connecting frame 121, thereby driving the drive gear 119 to rotate. The rotation of the drive gear 119 drives the transmission gear 115 to rotate, and in turn drives the intermediate gear 117 and the adjusting gear 116 to rotate. Thus, the rotation of the adjusting gear 116 drives the sealing block 109 to rotate within the discharge housing 108, thereby adjusting the position of the sealing block 109 within the discharge housing 108.

[0069] The hanging rack 3 is equipped with an anti-drip component to prevent residual yogurt at the filling channel opening of the closed filling component from dripping outside the bottle, such as... Figure 3 , Figure 4 As shown, the anti-drip assembly includes a receiving frame 201 and a fourth drive component 203. Sliding sleeves 202 are fixedly installed at both ends of the receiving frame 201. The two sliding sleeves 202 are slidably installed on the hanging frame 3. Two fourth drive components 203 are installed on the hanging frame 3. The output ends of the two fourth drive components 203 are fixedly connected to the two sliding sleeves 202 respectively.

[0070] When it is necessary to fill yogurt, the fourth drive component 203 is activated. The fourth drive component 203 pushes the sliding sleeve 202 to move, thereby adjusting the position of the receiving frame 201. The receiving frame 201 is then moved away from the bottom outlet position of the discharge shell 108, and the filling operation can be carried out.

[0071] After filling is completed, the fourth drive unit 203 can be retracted, thereby moving the receiving frame 201 back to the bottom outlet position of the discharge shell 108. If there is still yogurt left at the outlet position of the discharge shell 108, it will fall into the receiving frame 201 and will not drip onto the yogurt bottle or the conveyor belt of the conveying equipment 2.

[0072] The positioning frame 8 is fixedly mounted on the outer casing of the conveying equipment 2. The positioning frame 8 is equipped with a positioning clamping assembly used to restrict the position of the yogurt bottles to be filled within the corresponding filling station before filling. Figures 9 to 11 As shown, the positioning and clamping assembly includes a pusher frame 301 and a fifth drive member 302. Two pusher frames 301 are symmetrically and slidably mounted on the positioning frame 8. The fifth drive member 302 is fixedly installed on both sides of the positioning frame 8. The output ends of the fifth drive members 302 on both sides of the positioning frame 8 are fixedly connected to the two pusher frames 301 respectively. Several limit frames 303 are provided on each of the two pusher frames 301. Each limit frame 303 is equipped with a fastener 304, which consists of fastening screws and nuts, and is used to fix the relative position between the limit frame 303 and the pusher frame 301. Each limit frame 303 is equipped with a clamping block 305. Several clamping blocks 305 on one pusher frame 301 correspond one-to-one with several clamping blocks 305 on the other pusher frame 301 and are arranged symmetrically.

[0073] Among them, the first driving component 5, the second driving component 111, the third driving component 120, the fourth driving component 203 and the fifth driving component 302 are preferably all configured as electric cylinders.

[0074] During the yogurt filling process, after the yogurt bottle is carried by the bottle holder 4 and moves to the filling station by the chain conveyor belt, the conveyor equipment 2 can be temporarily shut down. At this time, the yogurt bottle is not in a vertical position in the bottle holder 4, and there is a certain deviation between the position of the bottle mouth and the center of the filling nozzle. Therefore, it is necessary to correct the position of the yogurt bottle and fix the yogurt bottle before filling.

[0075] At this time, the fifth drive unit 302 is activated, thereby simultaneously pushing the two pushers 301 to move synchronously, thereby pushing the corresponding limiter 303 and clamping block 305 to move, thus restricting the corresponding yogurt bottle to the center position directly below the outlet of the discharge shell 108. The clamping block 305 ensures that the yogurt bottle remains vertical throughout the filling process and does not shift due to milk flow impact or equipment vibration.

[0076] Once the yogurt filling is complete, the fifth drive component 302 can be retracted, causing the clamping block 305 to detach from the yogurt bottle. Then, the conveyor 2 can be restarted to move the filled yogurt bottle out of the filling station. At the same time, the next set of empty yogurt bottles enters the filling station, and the filling process can be restarted.

[0077] When filling yogurt using the filling device, first connect the output end of the yogurt conveying device to the corresponding conveying pipe 107, then turn on the conveying device 2, and then place the yogurt bottles into the corresponding bottle holders 4 one by one. After the yogurt bottles are carried by the bottle holders 4 and moved to the filling station by the chain conveyor belt, the conveying device 2 can be temporarily turned off. At this time, the yogurt bottles are not in a vertical position in the bottle holders 4, and there is a certain deviation between the position of the bottle mouth and the center of the filling nozzle. At this time, the fifth driving component 302 is activated, thereby simultaneously pushing the two pushing frames 301 to move synchronously, thereby pushing the corresponding limit frame. By moving 303 and clamping block 305, the corresponding yogurt bottle can be restricted to the center position directly below the outlet of the discharge shell 108. The clamping block 305 ensures that the yogurt bottle remains vertical throughout the filling process and does not shift due to milk flow impact or equipment vibration. At this time, the fourth drive component 203 is activated, which pushes the sliding sleeve 202 to move, thereby adjusting the position of the receiving frame 201 and moving the receiving frame 201 away from the bottom outlet position of the discharge shell 108, providing operating space for the downward movement of the filling tube 103, and the filling operation can then be carried out.

[0078] When filling yogurt, the first drive unit 5 is activated, which pushes the assembly bracket 6 to move downward. This, in turn, moves all the adjusting and fixing brackets 101, thereby causing the corresponding mounting cylinder 102 and filling pipe 103 to move downward until the discharge shell 108 is moved into the bottle, reaching the filling position. At this time, the yogurt conveying device is activated to input the yogurt into the conveying pipe 107, and then into the intermediate tank 104 through the input connector 105. The yogurt entering the intermediate tank 104 enters the filling pipe 103 through the connecting pipe 106, and can then be input into the yogurt bottle through the discharge shell 108. During this process, the first drive unit 5 is slowly retracted until a certain amount of yogurt is input into the yogurt bottle.

[0079] Since the second drive component 111 is normally in the ejected state, after the yogurt filling is completed, the discharge shell 108 is removed from the yogurt bottle. At this time, the second drive component 111 is activated first, and the piston 112 is retracted. This increases the volume of the intermediate tank 104 by adjusting the position of the piston 112 inside the sealing cylinder 110. This causes the yogurt inside the filling pipe 103 that has not entered the bottle to be lifted upwards a certain distance towards the intermediate tank 104, thereby actively drawing back the residual liquid at the outlet of the discharge shell 108 and allowing it to enter the interior of the discharge shell 108. Then, the third drive unit 120 is activated. The third drive unit 120 pushes the rack 118 to move through the connecting frame 121, thereby driving the drive gear 119 to rotate. The rotation of the drive gear 119 drives the transmission gear 115 to rotate, and in turn drives the intermediate gear 117 and the adjusting gear 116 to rotate. The rotation of the adjusting gear 116 drives the sealing block 109 to rotate inside the discharge housing 108, thereby adjusting the position of the sealing block 109 inside the discharge housing 108, so that it moves from... Figure 7 The shown on state has been adjusted to Figure 8 The closed state shown completes the filling process, preventing residual liquid at the outlet of the discharge shell 108 from dripping onto the yogurt bottle or the conveyor belt of the conveying equipment 2.

[0080] After filling is completed, the fourth drive component 203 can be retracted, thereby moving the receiving frame 201 back to the bottom outlet position of the discharge shell 108. If there is still yogurt remaining at the outlet position of the discharge shell 108, it will fall into the receiving frame 201 and will not drip onto the yogurt bottle or the conveyor belt of the conveying equipment 2. At the same time, the fifth drive component 302 is retracted, causing the clamping block 305 to detach from the yogurt bottle. Then, the conveying equipment 2 is restarted to move the filled yogurt bottle out of the filling station. At the same time, the next set of empty yogurt bottles enters the filling station, and filling can be restarted again.

[0081] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
