Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a feeding structure for a packaging machine. Background Technology

[0002] In the food packaging industry, filling is a widely used core packaging process, applicable to the production and processing of various foods. The filling demand for powdered foods, canned fruits, and other liquid foods is particularly prominent. The rationality of the filling process is directly related to food production efficiency, product hygiene, and equipment operation and maintenance costs.

[0003] Currently, most food filling equipment on the market is made of metal. Due to limitations in metal processing technology, equipment assembly precision, and assembly characteristics, there are inevitably certain gaps between the various connection parts of the equipment. At the same time, in order to avoid hard friction between the filling outlet and the filling mold and to prevent wear of parts and extend the service life of the equipment, an appropriate gap is usually reserved between the two.

[0004] However, in actual filling processes, these gaps and reserved spaces can lead to obvious drawbacks: when filling powdered materials, the powder can easily overflow from the gaps; when filling liquid foods, the liquid can easily leak from the gaps. This not only causes unnecessary waste of materials, but also contaminates the surface of the filling equipment and the surrounding production area, significantly increasing the difficulty of cleaning the equipment and affecting its cleanliness.

[0005] Because the food industry has stringent requirements for production hygiene, inadequate or untimely equipment cleaning not only increases equipment maintenance costs but may also create food safety hazards, making it difficult to meet the industry's demands for efficient and hygienic production. Therefore, there is an urgent need to develop a technical solution that can effectively seal gaps and prevent material leakage, in order to optimize the filling process, ensure equipment cleanliness, reduce maintenance costs, and meet the actual production needs of the food packaging industry. Utility Model Content

[0006] The purpose of this invention is to provide a feeding structure for a packaging machine, which effectively seals gaps and prevents material leakage.

[0007] To achieve the above objectives, this utility model provides a feeding structure for a packaging machine, including a frame and a feeding mechanism mounted on the frame. The feeding mechanism includes a conveying dynamic engagement unit and a static engagement unit that engages with the conveying dynamic engagement unit.

[0008] The conveying dynamic mating unit is placed inside the static mating unit and forms a reciprocating motion relative to the static mating unit in the horizontal direction. The mutual sliding contact surfaces of the conveying dynamic mating unit and the static mating unit are provided with a non-metallic wear-resistant layer.

[0009] The conveying dynamic mating unit and the static mating unit are spatially adjusted through a positioning floating structure. That is, the positioning floating structure restricts the relative displacement of the two in the horizontal direction and allows the conveying dynamic mating unit to adaptively float relative to the static mating unit in the vertical direction.

[0010] The conveying dynamic unit is provided with a material output end, and the static unit is provided with a material output channel adapted to the material output end.

[0011] When the conveying unit moves to the set position, the material output end is connected to the material output channel to form a material conveying path.

[0012] Preferably, the feeding mechanism further includes a power output component, one end of which is fixedly connected to the static fitting unit and the other end is drivenly connected to the conveying dynamic fitting unit, for driving the conveying dynamic fitting unit to reciprocate in the horizontal direction.

[0013] Preferably, the feeding mechanism further includes a horizontal guide component, which is connected to the conveying dynamic engagement unit and is used to guide and limit the horizontal movement of the conveying dynamic engagement unit.

[0014] Preferably, the static fitting unit includes a positioning support member and a limiting wall. The limiting wall and the positioning support member cooperate to form a guide space. The positioning support member has the material output channel. The conveying dynamic fitting unit reciprocates in the horizontal direction within the guide space.

[0015] The conveying dynamic cooperation unit includes a conveying carrier and a sealing wall. The sealing wall cooperates with the conveying carrier to form a material receiving cavity. The conveying carrier is provided with the material output end.

[0016] The mutual sliding contact surfaces of the positioning support and the conveying support are non-metallic wear-resistant surfaces;

[0017] The conveying dynamic mating unit and the static mating unit are made of non-metallic wear-resistant material as a whole, or a non-metallic wear-resistant layer is provided on the mutual sliding contact surface of the positioning bearing and the conveying bearing.

[0018] Preferably, the positioning floating structure includes a limiting part and a floating part that cooperate with each other; the limiting part is used to constrain the relative movement range of the conveying moving unit and the static unit in the horizontal direction, and the floating part is used to release the rigid constraint of the conveying moving unit and the static unit in the vertical direction, so that there is an adaptively adjustable vertical space between them.

[0019] Preferably, the conveying dynamic coordination unit further includes a material switching component, which includes a driving component and an L-shaped switching actuation component;

[0020] The driving component is located on the side of the positioning support that is away from the conveying support; one end of the L-shaped on / off actuator can movably cover the material conveying passage, and the other end is connected to the output end of the driving component.

[0021] Preferably, the static fitting unit further includes a material guiding component; the material guiding component includes a guiding body and a fixing component, the fixing component is fixedly disposed on the downstream side of the on / off execution component, and the guiding body is fixedly connected to the fixing component; the guiding body has two through ports, one through port covering the material conveying passage, and the other through port for outputting material to the next process.

[0022] Preferably, the conveying dynamic mating unit further includes an anti-jamming component;

[0023] The anti-jamming component includes an anti-jamming drive component and an anti-jamming execution component. The anti-jamming drive component is fixedly connected to the conveying dynamic cooperation unit, and its output end is drivenly connected to the anti-jamming execution component.

[0024] After the material is conveyed to the next process through the material conveying path, the anti-jamming drive component drives the anti-jamming execution component to extend into the material conveying path to remove residual material.

[0025] Beneficial effects

[0026] This invention utilizes a positioning and floating structure to spatially adjust the conveying dynamic and static mating units. This structure restricts the relative horizontal displacement of the two units while allowing the dynamic unit to adaptively float relative to the static unit in the vertical direction. Combined with a non-metallic wear-resistant layer on the sliding contact surfaces, this creates a dynamic adaptive seal, eliminating traditional rigid gaps. Even with long-term operation or manufacturing errors, the sliding interface remains tightly fitted, preventing powder spillage and liquid leakage, significantly improving the cleanliness of the equipment surface and surrounding areas. Simultaneously, the anti-jamming component on the dynamic unit actively extends into the material conveying path during reset, removing residual material at the cutting interface. This fundamentally prevents material from being sheared, squeezed, and jammed into the sliding surface, ensuring smooth and unobstructed feeding and significantly improving equipment reliability. Furthermore, based on the aforementioned leak-free and jam-free structural characteristics, the equipment does not require frequent shutdowns for cleaning or troubleshooting. The self-lubricating properties of the non-metallic wear-resistant layer reduce wear on metal parts, effectively extending the replacement cycle of vulnerable parts, thereby significantly reducing manual cleaning costs, maintenance time costs, and spare parts replacement costs.

Detailed Implementation

[0036] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0037] like Figure 1As shown, this embodiment provides a feeding structure for a packaging machine, including a frame and a feeding mechanism 200 fixedly installed on the frame. A feeding device (not shown, such as a vibrating plate or hopper) is provided above the feeding mechanism 200 for supplying materials to be packaged to the feeding mechanism 200; a conveying mechanism (not shown, such as a conveyor belt) is provided below the feeding mechanism 200 for receiving and conveying the materials output from the feeding mechanism 200, so as to send the materials into subsequent packaging processes.

[0038] Specifically, a non-metallic wear-resistant layer 240 is provided on the sliding contact surface between the conveying dynamic mating unit 210 and the static mating unit 220. This wear-resistant layer can be made of polytetrafluoroethylene (PTFE), ultra-high molecular weight polyethylene (UHMW-PE), or other non-metallic materials with low friction coefficient and high wear resistance. The core functions of this wear-resistant layer are: first, to reduce the frictional resistance during relative movement of the two units, making the operation smoother and reducing power loss; second, to utilize the flexibility of the non-metallic material itself to form a tighter seal with the cooperation of the floating structure; and third, to avoid the heat generation problem caused by metal-to-metal hard friction. After prolonged relative movement, the temperature of the metal friction pair increases, and the coefficient of friction rises accordingly. The sliding surface is prone to stickiness and sluggishness, making the operation increasingly difficult and affecting the feeding positioning accuracy and stability. In contrast, the non-metallic wear-resistant layer 240 has good self-lubricating properties, low thermal conductivity, and generates less frictional heat that does not easily accumulate. It maintains smooth and stable operation over long-term continuous operation without sluggishness, thus ensuring the durability and reliability of the equipment.

[0039] In one embodiment, the conveying dynamic mating unit 210 and the static mating unit 220 can be manufactured entirely from the aforementioned non-metallic wear-resistant material. This method eliminates the need for an additional wear-resistant layer, as the material itself possesses wear-reducing, self-lubricating, and heat-resistant properties, resulting in a simpler structure.

[0040] In a preferred embodiment, the static fitting unit 220 specifically includes a rigid positioning support member 221 and limiting walls 222 located on both sides or circumferentially thereon. The limiting walls 222 and the positioning support member 221 cooperate to form a precise guide space. The upper or lower surface of the positioning support member 221 is provided with the material output channel 223. The conveying dynamic fitting unit 210 is accommodated within this guide space and reciprocates therein in the horizontal direction.

[0041] Accordingly, the conveying dynamic engagement unit 210 includes a conveying support member 211 and a sealing wall 212. The sealing wall 212 and the conveying support member 211 together form a material receiving cavity for temporarily storing the material to be conveyed. The bottom of the conveying support member 211 (or the surface opposite to the positioning support member 221) is provided with the material output end 213. In particular, the upper surface (the surface that slides in contact with the conveying support member 211) and the lower surface of the conveying support member 211 are both covered with the non-metallic wear-resistant layer 240, or at least one of the surfaces is covered with the wear-resistant layer.

[0042] In another embodiment, the substrates of the conveying dynamic mating unit 210 and the static mating unit 220 are still made of metal, with a layer of non-metallic wear-resistant material only provided / or added on the mating surfaces where they slide against each other. This approach combines the structural strength of the metal substrate with the tribological advantages of the non-metallic surface, facilitating modifications or partial replacements on existing equipment.

[0043] Furthermore, the conveying dynamic mating unit 210 and the static mating unit 220 are spatially adjusted via a positioning floating structure 250. This positioning floating structure 250 includes a limiting structure 251 and a floating structure 252, used to limit the relative displacement of the conveying dynamic mating unit 210 and the static mating unit 220 in the horizontal direction, and to allow the conveying dynamic mating unit 210 to adaptively float relative to the static mating unit 220 in the vertical direction.

[0044] Example 1

[0045] The positioning floating structure 250 is achieved through the cooperation of a guide pin and an elongated hole. Specifically, as shown in the figure: a guide pin is fixedly provided at the power output end of the power output assembly 231, and an elongated hole is correspondingly provided on the conveying dynamic engagement unit 210. The horizontal dimension of the elongated hole matches the diameter of the guide pin, and its two horizontal end faces form a short side, which abuts against the guide pin to limit the horizontal movement of the conveying dynamic engagement unit 210 relative to the power output assembly 231, ensuring that the two move relative to each other within a preset effective stroke, thus forming the limiting structure 251. The vertical dimension of the elongated hole is larger than the diameter of the guide pin, and its two vertical end faces form a long side. A movement gap is reserved between this long side and the guide pin to allow the conveying dynamic engagement unit 210 to adaptively float relative to the power output assembly 231 in the vertical direction, thus forming the floating structure 252.

[0046] It should be noted that the above-described fit between the guide pin and the elongated hole is only one specific embodiment. Those skilled in the art will understand that as long as the horizontal limiting and vertical floating functions between the conveying dynamic fitting unit 210 and the static fitting unit 220 can be achieved, other implementations of the positioning floating structure 250 (such as setting the guide pin on the static fitting unit 220) are also feasible, and these variations do not depart from the protection scope of this utility model.

[0047] With the aforementioned positioning floating structure 250, when the conveying dynamic mating unit 210 is subjected to an external force in the vertical direction or encounters uneven installation, it can automatically adjust its vertical position, so that the non-metallic wear-resistant layer 240 always maintains uniform and tight contact with the relative sliding surface of the static mating unit 220, thereby dynamically compensating for processing errors and assembly tolerances, and eliminating friction caused by rigid gaps.

[0048] Example 2

[0049] The conveying dynamic coupling unit 210 is rigidly connected to the power output component 231; the static coupling unit 220 can float vertically relative to the frame.

[0050] A limiting structure 251 is disposed between the static fitting unit 220 and the frame to limit horizontal displacement. In one embodiment, the frame is provided with a horizontal guide groove, and the static fitting unit 220 is provided with a guide protrusion. The two ends of the guide groove abut against the protrusion to limit the horizontal stroke.

[0051] A floating structure 252 is disposed between the static fitting unit 220 and the frame to allow vertical floating. In one embodiment, the frame is provided with vertical guide posts, and the static fitting unit 220 has vertical guide holes, through which the guide posts pass and with a vertical movement clearance. The static fitting unit 220 rests on the frame under its own weight, or is supported by compression springs.

[0052] During operation, the power output component 231 drives the conveying dynamic mating unit 210 to move horizontally, and the static mating unit 220 automatically floats up and down, so that the non-metallic wear-resistant layer 240 keeps in close contact with the sliding surface.

[0053] Example 3

[0054] The power output assembly 231 is mounted on a floating platform, which can float vertically relative to the frame; the conveying dynamic mating unit 210 is rigidly connected to the power output end of the power output assembly 231; the static mating unit 220 is fixed to the frame.

[0055] A limiting structure 251 is disposed between the power output assembly 231 and the frame to limit horizontal displacement. In one embodiment, the frame is provided with a horizontal guide rail, the mounting base of the power output assembly 231 is provided with a slider, and limiting blocks are provided at both ends of the guide rail.

[0056] A floating structure 252 is disposed between the power take-off assembly 231 and the frame to allow vertical floating. In one embodiment, the frame has a vertical guide pin, and the mounting base has a vertical elongated hole into which the guide pin passes, leaving a vertical movement clearance. The power take-off assembly 231 rests on the frame by its own weight or is supported by a compression spring.

[0057] During operation, the power output component 231 drives the conveying dynamic mating unit 210 to move horizontally. When vertical adjustment is required, the two float up and down together, while the static mating unit 220 remains fixed, so that the sliding surface of the non-metallic wear-resistant layer 240 and the static mating unit 220 always remain in close contact.

[0058] Example 4

[0059] The power output assembly 231 and the conveying dynamic engagement unit 210 are connected by a flexible transmission component, which is one of a chain, synchronous belt, or wire rope. This flexible transmission component only transmits horizontal tension or thrust and does not constrain the vertical position. The conveying dynamic engagement unit 210 rests directly on the sliding surface of the static engagement unit 220 and maintains contact with the non-metallic wear-resistant layer 240 by its own weight.

[0060] A limiting structure 251 is disposed between the conveying dynamic mating unit 210 and the static mating unit 220 to limit the horizontal movement stroke. In one embodiment, the static mating unit 220 is provided with limiting blocks at both horizontal ends, which abut against the conveying dynamic mating unit 210 when it moves to its limit position.

[0061] The floating structure 252 is composed of the weight of the conveying dynamic mating unit 210 and its contact relationship with the static mating unit 220. Since the flexible transmission component does not transmit vertical force, the conveying dynamic mating unit 210 is not constrained in the vertical direction and can float up and down with the contour of the sliding surface to maintain a close fit.

[0062] During operation, the power output component 231 drives the conveying dynamic coordination unit 210 to reciprocate horizontally via a flexible transmission component. When it moves to the set position, the material output end 213 and the material output channel 223 are connected vertically to form a material conveying path.

[0063] See Figure 2The feeding mechanism includes a power output component 231 (e.g., a cylinder, hydraulic cylinder, linear motor, or servo motor and lead screw assembly) and a horizontal guide component 232 (e.g., a linear slide rail pair or a guide shaft and linear bearing pair). One end of the power output component 231 is fixedly connected to the positioning support member 221 of the static fitting unit 220, which serves as a fixed base, and the other end (i.e., the movable end) is drively connected to the conveying support member 211 of the conveying dynamic fitting unit 210 to provide stable reciprocating motion power. The horizontal guide component 232 has an elongated hole and is also fixedly connected to the guide pin on the static fitting unit 220, forming a horizontal sliding fit relationship with the conveying dynamic fitting unit 210, thereby precisely guiding and limiting the horizontal movement of the conveying dynamic fitting unit 210 and ensuring the straightness of its movement trajectory.

[0064] To achieve automated control of material output, this device also includes a material on / off assembly 260. The material on / off assembly 260 includes a drive component 261 (such as a miniature cylinder or electromagnet) and an L-shaped on / off actuator 262 (i.e., an L-shaped baffle). The drive component 261 is fixedly installed on the side of the positioning support 221 away from the conveying support 211 (i.e., below), and its output end passes upward through the positioning support 221 and connects to the L-shaped on / off actuator 262. The L-shaped on / off actuator 262 is positioned on the path of the material output channel 223 and is used to quickly open or close the material conveying passage according to instructions.

[0065] In addition, to accurately guide the material into the packaging container, the static fitting unit 220 also includes a material guiding assembly 270. This assembly includes a guide body 271 (such as a funnel or conduit) and a fixing component 272. The fixing component 272 is fixedly disposed downstream of the L-shaped on / off actuator 262 (i.e., behind in the material output direction) and fixedly connected to the guide body 271. The guide body 271 has two through-holes, one through-hole covering the material output channel 223, and the other through-hole for outputting the material to the next process so that it falls accurately into the packaging container below.

[0066] See Figure 4To address the potential jamming issue when materials are closed, the conveying dynamic coordination unit 210 further includes an anti-jamming component 280. This anti-jamming component 280 comprises an anti-jamming drive component 281 (e.g., a miniature cylinder) and an anti-jamming actuation component 282 (e.g., a push rod). The anti-jamming drive component 281 is fixedly connected to the sealing wall 212 of the conveying dynamic coordination unit 210, and its output end is drively connected to the anti-jamming actuation component 282. When a feeding cycle is completed, the power output component 231 drives the entire conveying dynamic coordination unit 210 to move horizontally in the reset direction (i.e., the direction in which the material output end 213 and the material output channel 223 are misaligned). At the end of the movement, the anti-jamming drive component 281 drives the anti-jamming execution component 282 to briefly extend from the side or vertical into the material conveying passage (especially the opening of the material output end 213 or the material output channel 223 or the material guide component 270) to forcibly clean up any material that may remain in the area due to gravity or adhesion. This prevents the material from being squeezed, cut off, or stuck between the sliding surfaces during relative shearing motion, ensuring the accuracy of the amount of material fed next time and the reliability of the operation.

[0067] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
