DETAILED DESCRIPTION

[0020] Clearly, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0021] Please refer to Figure 1 and Figure 2 In some embodiments, the present application provides a pouring residual liquid extraction device for extracting residual liquid in a container. The container is used to package liquid or semi-liquid, and has a receiving cavity inside and an opening at the top, which can be sealed by a cover. The shape of the container can be one of circular, rectangular or other polygonal. In this embodiment, a rectangular container is taken as an example for description.

[0022] The pouring residual liquid extraction device includes a conveyor 1, an inclined barrel mechanism 2 and a liquid extraction mechanism 3.

[0023] The conveyor 1 is a roller conveyor 1, and the positioning station of the conveying surface is adapted to the shape of the bottom of the container. For example, if the container is a rectangular barrel, the positioning station is rectangular.

[0024] The inclined barrel mechanism 2 is arranged at the bottom of the conveyor 1, and specifically includes a barrel blocking assembly 21, a barrel holding assembly 22 and a jacking assembly 23. The barrel blocking assembly 21 positions the container in the conveying direction on the positioning station; the barrel holding assembly 22 clamps the side wall of the container; and the jacking assembly 23 drives the conveyor 1 to tilt so that the container is diagonally inclined.

[0025] The liquid extraction mechanism 3 is arranged above the conveyor 1, and includes a pipe 31, a liquid extraction ball head 32, a liquid extraction pump (not shown) and a winding assembly 33. The pipe 31 is connected to the liquid extraction ball head 32 at the end, the liquid extraction pump provides suction through the pipe 31, and the winding assembly 33 drives the pipe 31 to retract and extend, so that the liquid extraction ball head 32 moves to the diagonal position at the bottom of the inclined container.

[0026] Through the cooperation of the conveyor 1, the inclined barrel mechanism 2 and the liquid extraction mechanism 3, the positioning, tilting and extraction of residual liquid of the container are realized. The cooperation of the barrel blocking assembly 21 and the barrel holding assembly 22 ensures that the container is stably positioned on the positioning station during conveying and tilting; the jacking assembly 23 enables the container to be accurately diagonally inclined, which facilitates the gathering of residual liquid to a specific position; the winding assembly 33 of the liquid extraction mechanism 3 drives the liquid extraction ball head 32 to move accurately to the diagonal position where the residual liquid is gathered, and the liquid extraction pump realizes efficient extraction of residual liquid, solving the problems of difficulty in collecting residual liquid, damage to the barrel body and residual liquid in dead corners during tilting of the barrel in the prior art, reducing the residual amount of cleaning solvent in the barrel, improving the use efficiency of the cleaning machine and the filling quality, and reducing resource waste and environmental pollution.

[0027] Referring to Figure 3 As shown in some embodiments, the blocking barrel assembly 21 includes a pair of first cylinders 211 and a pair of corresponding blocks 212. The pair of first cylinders 211 are double-acting cylinders symmetrically installed on both sides of the output end of the conveyor 1. The cylinder body is fixed on the rack of the conveyor 1 through a support, and the extension direction of the piston rod is perpendicular to the conveying direction. The block 212 is fixedly connected to the front end of the piston rod through a bolt.

[0028] The double-acting cylinder can provide stable pushing force and pulling force to ensure that the block 212 reliably blocks the container. The symmetric arrangement ensures the uniformity of the container blocking force, allowing the container to be accurately positioned on the positioning station and avoiding the container from shifting during conveying, thereby providing a stable basis for subsequent barrel holding and tilting operations.

[0029] Further, the side surface of the block 212 towards the container is a concave arc surface, and the curvature of the concave arc surface matches the outer contour of the two adjacent corners of the container. The block 212 is made of high-strength wear-resistant material, such as cast iron or hard alloy, and is fixedly connected to the end of the piston rod of the first cylinder 211 through a bolt. The arc surface is pasted with a 5-10mm thick rubber or silicone buffer layer.

[0030] The matching of the concave arc surface with the outer contour of the container side wall increases the contact area between the block 212 and the container, allowing the blocking force to be uniformly distributed on the container side wall, avoiding local extrusion and damage to the container side wall, and improving the stability and reliability of container positioning. The use of high-strength wear-resistant material prolongs the service life of the block 212 and reduces the maintenance cost of the equipment, solving the problem of container damage and unstable positioning caused by the small contact area between the block 212 and the container in the prior art. Referring to Figure 3 As shown in some embodiments, the barrel holding assembly 22 includes a pair of second cylinders 221 and a pair of corresponding clamping blocks 222. The pair of second cylinders 221 are also double-acting cylinders symmetrically installed on both sides of the conveyor 1 rack in the middle of the positioning station. The cylinder body is fixed through a support, and the front end of the piston rod is fixedly connected to the clamping block 222 through a bolt. The clamping surface of the clamping block 222 is pasted with a soft buffer layer made of rubber or silicone with a thickness of 5-10mm.

[0031] The double-acting cylinder can provide sufficient clamping force to firmly clamp the container. The symmetric arrangement ensures the uniformity of the clamping force, avoiding deformation of the container during clamping. The soft buffer layer serves as a buffer to reduce damage to the container side wall caused by the clamping force, protecting the appearance and structure of the container and improving the secondary utilization value.

[0032] Referring to Figure 3 and Figure 4As shown, in some embodiments, the jacking assembly 23 comprises a chassis support 231 and a jacking cylinder 232. The chassis support 231 is a metal frame structure fixed to the ground by anchor bolts.

[0033] The bottom of the conveyor 1 is hingedly connected to the chassis support 231 through a first hinged shaft 233. Specifically, the bottom of the conveyor 1 is fixedly provided with a first bearing seat adapted to the first hinged shaft 233; the chassis support 231 is fixedly provided with a first double lug plate having a first mounting hole. The first hinged shaft 233 passes through the first mounting hole of the first double lug plate at both ends and is fixedly installed on the first double lug plate; the middle part is in rotational cooperation with the first bearing seat.

[0034] The jacking cylinder 232 is a single-acting cylinder hingedly connected to the upper surface of the chassis support 231 through a second hinged shaft 234, and the driving end is hingedly connected to the bottom of the conveyor 1 through a third hinged shaft 235. Specifically, the first hinged shaft 233, the second hinged shaft 234 and the third hinged shaft 235 are axially parallel, and the upper surface of the chassis support 231 is fixedly provided with a second bearing seat adapted to the second hinged shaft 234; the bottom of the cylinder body of the jacking cylinder 232 is fixedly provided with a second double lug plate having a second mounting hole. The second hinged shaft 234 passes through the mounting hole of the second double lug plate at both ends and is fixedly installed on the second double lug plate; the middle part is in rotational cooperation with the second bearing seat. The bottom of the conveyor 1 is fixedly provided with a third bearing seat adapted to the third hinged shaft 235; the piston rod of the jacking cylinder 232 is fixedly provided with a third double lug plate having a third mounting hole. The third hinged shaft 235 passes through the third mounting hole of the third double lug plate at both ends and is fixedly installed on the third double lug plate; the middle part is in rotational cooperation with the third bearing seat.

[0035] The metal frame chassis support 231 provides stable support, and the anchor bolt fixation ensures the stability of the jacking assembly 23; the jacking cylinder 232 provides sufficient driving force to drive the conveyor 1 to rotate around the first hinged shaft 233, so that the container is accurately diagonally inclined, which facilitates the collection of residual liquid and creates conditions for efficient liquid pumping.

[0036] In some embodiments, the jacking cylinder 232 is provided in pairs and symmetrically distributed along the first diagonal line of the conveyor 1. Specifically, one of the jacking cylinders 232 is located at the middle of the bottom of the input end of the conveyor 1, and the other is located at the middle of the bottom of the first side edge of the conveyor 1. At this time, the first hinged shaft 233, the second hinged shaft 234 and the third hinged shaft 235 are axially perpendicular to the first diagonal line. This ensures that the driving force of the conveyor 1 is evenly distributed, so that the conveyor 1 can smoothly rotate around the first hinged shaft 233, avoiding the inclination or shaking of the conveyor 1 during the inclination process, and ensuring the accuracy and stability of the inclination angle of the container.

[0037] In some embodiments, the first hinge shaft 233 is provided in pairs, and the pairs of first hinge shafts 233 are symmetrically distributed along the first diagonal line of the conveyor 1. Specifically, one of the first hinge shafts 233 is located at the middle of the bottom of the output end of the conveyor 1, and the other is located at the middle of the bottom of the second side of the conveyor 1, which is opposite to the first side of the conveyor 1.

[0038] By symmetrically distributing the pairs of first hinge shafts 233 along the first diagonal line, the conveyor 1 is further provided with stable support and rotation axis, so that the conveyor 1 can rotate around the stable axis during tilting, avoiding the problem of unstable tilting of the container caused by the deviation of the rotation axis.

[0039] In some embodiments, the pairs of jacking cylinders 232 are arranged in a rectangular shape with the pairs of first hinge shafts 233. The jacking cylinders 232 and the first hinge shafts 233 form a rectangular layout in space, forming a stable mechanical system to ensure uniform force at each connection point, further enhancing the stability and reliability of the conveyor 1 during tilting, and ensuring the accuracy of the tilting angle of the container, providing a more stable structural foundation for efficient residual liquid extraction.

[0040] In some embodiments, the upper surface of the chassis support 231 is provided with a first support frame 236, which is welded by channel steel, and the top of the first support frame 236 is fixed with a first double lug plate adapted to the first hinge shaft 233 by bolts or welding. The height of the first support frame 236 is accurately calculated and designed, and when the jacking cylinder 232 is in the initial contraction state, the axes of the first hinge shaft 233 and the second hinge shaft 234 are coplanar, at which time the conveying surface of the conveyor 1 remains horizontal. The initial contraction state of the jacking cylinder 232 is detected and controlled by a travel switch or a sensor.

[0041] The height design of the first support frame 236 ensures the horizontal conveying of the conveyor 1 in the initial state, facilitating the conveying and positioning of the container. The design of the coplanar axes of the first hinge shaft 233 and the second hinge shaft 234 ensures the force balance of the jacking cylinder 232 in the initial state, reduces unnecessary wear of the cylinder and hinge parts, and prolongs the service life of the equipment.

[0042] Please refer to Figure 2 and Figure 3As shown, in some embodiments, the winding assembly 33 includes a winding motor 331, a winding wheel 332 and a second support frame 333. The winding motor 331 is a servo motor, the output end is connected to a reducer through a shaft coupling, the reducer is a gear reducer, the output shaft is coaxially fixed to the winding wheel 332, and a helical groove is arranged on the outer circumferential surface of the winding wheel 332 for orderly winding and accommodating the winding pipe 31. The second support frame 333 is welded by angle steel, the top is provided with a winding wheel bearing seat, a bearing is installed in the winding wheel bearing seat for supporting the rotating shaft of the winding wheel 332, so that the winding wheel 332 can rotate around its axis. The winding motor 331 is connected with the control system of the equipment through a controller to realize accurate control of the rotation of the winding wheel 332.

[0043] Please refer to Figure 1 As shown, in some embodiments, the pouring type residual liquid extraction device further includes a protective cover 4. The protective cover 4 is composed of side baffles 41 located on both sides of the conveyor 1 and a top plate 42 on the top, wherein the winding motor 331, the winding wheel 332 and the second support frame 333 are detachably fixedly installed on the upper surface of the top plate 42 through bolts; the top plate 42 is provided with an avoidance hole for the winding pipe 31 to pass through, so as to facilitate the execution of the winding and unwinding action of the winding pipe 31.
