Description

Technical Field

[0001] This utility model relates to the field of dairy product production and processing technology, specifically to a linear filling and capping device for fermented milk production. Background Technology

[0002] Fermented milk, as a common dairy product, is rich in live probiotics, thus requiring high hygiene and sealing standards during the production process. In large-scale production, filling and capping are crucial steps, necessitating a continuous operation from filling the fermented milk into containers to installing the caps. Linear filling and capping systems are well-suited to the continuous production needs of fermented milk production lines, meeting the food industry's requirements for standardized production processes and controllable hygiene conditions. This helps ensure the quality and shelf life of fermented milk before it leaves the factory, making it an important type of equipment in modern fermented milk production.

[0003] Utility model patent CN217377293U discloses a dual-head following piston moving filling and capping integrated machine. This machine includes a base, on which a material conveying assembly is mounted. Support frame one and support frame two are mounted on one side of the base. Electric lifting rod one is mounted on support frame one, and a lifting plate is fixed to its bottom. Two filling heads are mounted on the lifting plate, and piston filling assemblies are connected to the top of each filling head. Electric lifting rod two is mounted on support frame two, and a connecting plate is fixed to its bottom. Two capping assemblies are mounted on the bottom of the connecting plate. This dual-head following piston moving filling and capping integrated machine can convey filling bottles to the filling heads via the material conveying assembly for filling, and then cap the bottles after filling. This makes small-batch filling and capping more convenient and faster.

[0004] This dual-piston moving filling and capping machine only guides the material through baffles and does not actively clamp and position the bottle. When the bottle is a smooth glass bottle, it is easy for the glass bottle to shift during the intermittent movement of the conveyor belt or the pressing of the capping assembly, resulting in misalignment between the cap and the bottle mouth, affecting the accuracy of capping. At the same time, the capping process relies only on the clamping and rotational force of the electric capping jaws without fixing the glass bottle. Because the surface of the glass bottle is smooth, the bottle body is easy to rotate synchronously with the jaws during capping, making it difficult to tighten the cap and potentially resulting in poor sealing. In view of this, we propose a linear filling and capping device for fermented milk production. Utility Model Content

[0005] The purpose of this invention is to provide a linear filling and capping device for fermented milk production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A linear filling and capping device for fermented milk production includes a belt conveyor for conveying bottles, a capping device for installing bottle caps on the belt conveyor, and a positioning and clamping mechanism on the belt conveyor below the capping device. The positioning and clamping mechanism includes a base supported by support legs and a pair of clamping components mounted on the base. The two clamping components are used to clamp and position the bottle.

[0008] The base has protrusions on both the front and rear edges of the top. The height of the front protrusion is lower than that of the rear protrusion. The two clamping components are respectively installed on the two protrusions.

[0009] The clamping assembly includes a movable seat plate slidably connected to the boss, a clamping plate sleeved inside the movable seat plate and slidably connected to the movable seat plate, and an electric push rod for pushing the movable seat plate to move. A V-shaped clamping groove is opened at the first end face of the clamping plate. When the electric push rod is working, it drives the movable seat plate and the clamping plate to move toward the bottle, so that the bottle can be restricted between the two clamping plates on the two clamping assemblies.

[0010] Preferably, the top of the protrusion is provided with a sleeve groove, the end of the sleeve groove near the belt conveyor is open, the inner walls of the left and right sides of the sleeve groove are provided with first sliding grooves, the left and right end faces of the movable seat plate are provided with first protruding edges, the two first protruding edges are respectively inserted into the two first sliding grooves and can slide along the first sliding grooves.

[0011] In this configuration, the groove provides sliding space and guidance for the movable seat plate, and the first protruding edge cooperates with the first sliding groove to restrict the sliding direction of the movable seat plate and prevent it from deviating or falling off.

[0012] Preferably, the electric push rod is installed at the top position of the end face of the boss away from the belt conveyor, and the push rod end of the electric push rod extends into the sleeve groove and is fixedly connected to the tail end of the movable seat plate.

[0013] In this setting, the installation position ensures that the driving force of the electric push rod is aligned with the sliding direction of the movable seat plate, guaranteeing that the driving force is stably transmitted to the movable seat plate and enabling smooth sliding of the movable seat plate.

[0014] Preferably, a cavity is provided at the first end of the movable seat plate, and a second sliding groove is provided on the inner walls of both the left and right sides of the cavity. A second protruding edge is provided on the end face of both the left and right sides of the clamping plate. The two second protruding edges are respectively inserted into the two second sliding grooves and can slide along the second sliding grooves.

[0015] In this configuration, the cavity accommodates the clamping plate and provides it with sliding space. The second protruding edge cooperates with the second sliding groove to restrict the sliding direction of the clamping plate and ensure stable movement of the clamping plate.

[0016] Preferably, a stop block is fixed at both the left and right edges of the first end of the movable seat plate. The stop block blocks the first end of the second sliding groove and is used to prevent the clamping plate from coming out of the movable seat plate.

[0017] In this configuration, the stop block prevents the second convex edge from dislodging from the first end of the second sliding groove, thereby preventing the clamping plate from falling out of the movable seat plate and ensuring the integrity of the clamping assembly structure.

[0018] Preferably, a plurality of first sleeve holes are provided at the bottom of the sleeve cavity, and a plurality of second sleeve holes are provided on the tail end face of the clamping plate. The number of second sleeve holes is equal to that of the first sleeve holes and their positions correspond one-to-one. A spring is sleeved between the first sleeve holes and the second sleeve holes.

[0019] In this setup, the spring provides cushioning when the clamp contacts the bottle, preventing the bottle from being crushed and damaged. At the same time, the spring force keeps the clamp in contact with the bottle, maintaining a stable grip.

[0020] Preferably, a pair of threaded rods are fixed to the tail end face of the movable seat plate. The ends of the threaded rods pass through the outer end face of the boss and are threadedly connected to a pair of limiting nuts. By tightening the two limiting nuts on the threaded rods, the travel of the movable seat plate moving toward the belt conveyor on the boss is limited by the distance between the limiting nuts and the outer end face of the boss.

[0021] In this setting, by adjusting the distance between the limit nut and the outer end face of the boss, the maximum distance the movable seat plate slides towards the belt conveyor can be controlled, thus preventing the clamping plate from clamping the bottle too tightly.

[0022] Preferably, a rubber strip is embedded in the clamping groove of the clamping plate, and when the clamping assembly clamps the bottle, the bottle is pressed against the rubber strip;

[0023] In this design, the rubber strip increases the friction between the clamping groove and the bottle, preventing the bottle from slipping during clamping and avoiding direct contact between the clamping plate and the bottle, which could cause wear.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 1. The linear filling and capping device for fermented milk production uses a positioning and clamping mechanism to actively clamp and position the glass bottle as it moves to the capping point. This prevents the glass bottle from shifting due to its smooth surface, ensuring that the cap and bottle mouth are precisely aligned and guaranteeing the accuracy of the capping.

[0026] 2. The linear filling and capping device for fermented milk production uses a positioning and clamping mechanism to clamp the glass bottle during the capping process, making the bottle stable and fixed, preventing the bottle from rotating synchronously with the capping assembly, and enabling the capping assembly to generate an effective rotational torque, thereby reliably tightening the cap and improving the sealing effect.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0038] Please see Figures 1-6A linear filling and capping device for fermented milk production includes a belt conveyor 100 for conveying bottles 200. From left to right, the belt conveyor 100 is equipped with a filling machine, a cap placement device, and a capping device 110 for installing bottle caps. The filling machine can inject fermented milk into the bottle 200, the cap placement device can place the bottle cap at the mouth of the bottle 200 after filling, and the capping device 110 can complete the installation and fixation of the bottle cap to the bottle 200. The three work together to achieve a continuous operation of "filling-cap placement-capping". A positioning and clamping mechanism 300 is provided on the belt conveyor 100 below the capper 110. The positioning and clamping mechanism 300 includes a base 310 supported by support legs and a pair of clamping components 320 mounted on the base 310. The base 310 provides a stable mounting base for the clamping components 320. The support legs can keep the base 310 at a fixed distance from the ground to avoid the vibration of the belt conveyor 100 during operation from affecting the stability of the clamping components 320. The two clamping components 320 are used to clamp and position the bottle 200. The clamping assembly 320 includes a movable seat plate 321 slidably connected to the boss 311, a clamping plate 322 sleeved in the movable seat plate 321 and slidably connected to the movable seat plate 321, and an electric push rod 323 for pushing the movable seat plate 321 to move. The electric push rod 323 can provide a stable driving force to drive the movable seat plate 321 to slide along the boss 311, thereby causing the clamping plate 322 to move closer to or away from the bottle 200, realizing the clamping and releasing of the bottle 200. When working, the electric push rod 323 drives the movable seat plate 321 and the clamping plate 322 to move toward the bottle 200, so that the bottle 200 can be restricted between the two clamping plates 322 on the two clamping assemblies 320.

[0039] like Figures 2-4 As shown, in this utility model, both the front and rear edges of the top of the base 310 are provided with protrusions 311. The height of the front protrusion 311 is lower than that of the rear protrusion 311. The two clamping components 320 are respectively installed on the two protrusions 311. The protrusions 311 provide a mounting carrier for the clamping components 320, and the height difference between the front and rear protrusions 311 can make the two clamping components 320 misaligned in the vertical direction, so as to avoid the two clamping components 320 touching when clamping the bottle 200.

[0040] like Figure 5 and Figure 6As shown, specifically, a V-shaped clamping groove 3221 is provided at the first end face of the clamping plate 322. The V-shaped clamping groove 3221 can be adapted to cylindrical bottles 200 of different diameters, improving clamping stability. A rubber strip 3222 is embedded in the clamping groove 3221. When the clamping component 320 clamps the bottle 200, the bottle 200 presses against the rubber strip 3222. The rubber strip 3222 can increase the friction between the clamping groove 3221 and the bottle 200, further preventing the bottle 200 from sliding during the clamping process, while avoiding direct contact between the clamping plate 322 and the bottle 200, which would cause wear to the bottle 200.

[0041] like Figure 4 and Figure 5 As shown, further, a groove 312 is provided at the top of the protrusion 311. The end of the groove 312 near the belt conveyor 100 is open. The groove 312 can accommodate the movable seat plate 321 and provide guiding space for the sliding of the movable seat plate 321. The open end facilitates the movable seat plate 321 to drive the clamping plate 322 to extend towards the belt conveyor 100 and near the bottle body 200. First sliding grooves 313 are provided on the inner walls of both the left and right sides of the groove 312. First protruding edges 3216 are provided on the end faces of both the left and right sides of the movable seat plate 321. The two first protruding edges 3216 are respectively inserted into the two first sliding grooves 313 and can slide along the first sliding grooves 313. The cooperation between the first protruding edges 3216 and the first sliding grooves 313 can limit the sliding direction of the movable seat plate 321, prevent the movable seat plate 321 from deviating or falling off during the sliding process, and ensure the stability of the movement of the movable seat plate 321. The electric push rod 323 is installed at the top of the side face of the boss 311 away from the belt conveyor 100. This installation position allows the driving force direction of the electric push rod 323 to be consistent with the sliding direction of the movable seat plate 321, ensuring that the driving force is transmitted to the movable seat plate 321. The push rod end of the electric push rod 323 extends into the sleeve groove 312 and is fixedly connected to the tail end of the movable seat plate 321.

[0042] like Figure 5 and Figure 6As shown, a cavity 3211 is provided at the first end of the movable seat plate 321. The cavity 3211 can accommodate the clamping plate 322 and provide space for the sliding of the clamping plate 322. A second sliding groove 3212 is provided on the inner walls of both the left and right sides of the cavity 3211. A second protruding edge 3223 is provided on the end face of both the left and right sides of the clamping plate 322. The two second protruding edges 3223 are respectively inserted into the two second sliding grooves 3212 and can slide along the second sliding grooves 3212. The cooperation between the second protruding edges 3223 and the second sliding grooves 3212 can limit the sliding direction of the clamping plate 322, prevent the clamping plate 322 from shifting in the movable seat plate 321, and ensure the stable movement of the clamping plate 322. Stoppers 3213 are fixed at the left and right edges of the first end of the movable seat plate 321. The stoppers 3213 block the first end of the second sliding groove 3212 and prevent the second protruding edge 3223 from coming out of the first end of the second sliding groove 3212, thereby preventing the clamping plate 322 from coming out of the movable seat plate 321.

[0043] like Figure 5 As shown, it is worth noting that a number of first sleeve holes 3214 are provided at the bottom of the sleeve cavity 3211, and a number of second sleeve holes 3224 are provided on the tail end face of the clamping plate 322. The number of second sleeve holes 3224 is equal to that of the first sleeve holes 3214 and their positions correspond one-to-one. A spring 3215 is sleeved between the first sleeve holes 3214 and the second sleeve holes 3224. The spring 3215 can provide a buffering force after the clamping plate 322 contacts the bottle body 200, so as to avoid the bottle body 200 being squeezed and damaged due to excessive driving force of the electric push rod 323. At the same time, the elasticity of the spring 3215 can keep the clamping plate 322 always in contact with the bottle body 200 and maintain a stable clamping state.

[0044] like Figure 5 As shown, it is worth noting that a pair of threaded rods 3217 are fixed to the tail end face of the movable seat plate 321. The ends of the threaded rods 3217 pass through the outer end face of the boss 311 and are threadedly connected to a pair of limiting nuts 3218. By tightening the two limiting nuts 3218 on the threaded rods 3217, the travel of the movable seat plate 321 in the direction of the belt conveyor 100 on the boss 311 is limited by the distance between the limiting nuts 3218 and the outer end face of the boss 311. The threaded rods 3217 move synchronously with the movable seat plate 321. The limiting nuts 3218 can limit the travel of the threaded rods 3217 by adjusting the distance between them and the outer end face of the boss 311, thereby controlling the maximum distance that the movable seat plate 321 slides in the direction of the belt conveyor 100, and avoiding excessive movement of the movable seat plate 321 that causes the clamping plate 322 to clamp the bottle 200 too tightly.

[0045] It should be added that the electric push rod 323 involved in this utility model is existing conventional technology, and will not be described in detail in this utility model.

[0046] In this embodiment, the linear filling and capping device for fermented milk production operates as follows: First, the belt conveyor 100 transports empty bottles 200 from left to right. When the bottles 200 reach below the filling machine, the filling machine injects a measured amount of fermented milk into the bottles 200. Then, the filled bottles 200 continue to move with the belt conveyor 100. When passing the cap placement device, the cap placement device places the cap at the bottle opening of the bottle 200. Next, the belt conveyor 100 transports the bottles 200 with caps to below the capping device 110. At this time, the electric push rod 323 is activated, driving the movable seat plate 321 along the first sliding path of the protrusion 311. The groove 313 slides towards the bottle body 200, and the movable seat plate 321 drives the clamping plate 322 to approach the bottle body 200 until the rubber strip 3222 in the V-shaped clamping groove 3221 of the clamping plate 322 presses against the bottle body 200. The spring 3215 is adaptively compressed according to the diameter of the bottle body 200 to achieve stable clamping of the bottle body 200. Finally, the capping device 110 starts and moves downward to tighten the cap at the bottle mouth of the bottle body 200. After the capping is completed, the electric push rod 323 drives the movable seat plate 321 and the clamping plate 322 to reset and release the bottle body 200. The belt conveyor 100 transports the capped bottle body 200 to the next process.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
