Description

Technical Field

[0001] This utility model relates to the field of bagging machine technology, specifically to a bagging mechanism for inoculants and molding powder. Background Technology

[0002] In the packaging of powdered materials such as inoculants and molding powders, traditional bagging mechanisms have significant shortcomings in terms of bag fixing, material leakage prevention, and specification adaptability, making it difficult to meet the requirements of modern industrial production for efficiency, precision, and environmental protection.

[0003] Early bagging mechanisms mostly used rigid clamping methods to fix the cloth bags, such as pressing the bag opening with clamps or bolts. This method has obvious drawbacks: Firstly, the clamping force is uneven due to differences in the material and thickness of the cloth bags. During loading, the weight or impact of the material can easily cause the cloth bags to fall off, especially when the load is large, the risk of falling off increases significantly. During the loading process, gaps are formed at the contact surface between the cloth bag and the discharge cylinder due to loose clamping, and fine powdery inoculants and molding powder can easily leak from the gaps. At the same time, dust overflow not only pollutes the working environment but may also cause occupational health problems for operators. Moreover, dust accumulation inside the equipment accelerates the wear of mechanical parts and increases maintenance costs. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a bagging mechanism for inoculants and molding powders, which solves the technical problem that the bagging mechanism in the prior art does not firmly clamp the bag body.

[0005] According to one aspect, at least one embodiment of the present invention provides a bagging mechanism for inoculants and molding powders, comprising:

[0006] An annular mounting component is provided on a bagging machine, the bagging machine having a discharge cylinder that passes through the annular mounting component;

[0007] The first swing member and the second swing member are respectively swinging and disposed on both sides of the annular mounting member. After swinging, the first swing member and the second swing member move closer to each other or further away from each other. When the first swing member and the second swing member move closer to each other, they are used to press the cloth bag onto the discharge cylinder.

[0008] An anti-detachment component is slidably disposed on the first swing component and the second swing component. After sliding, the anti-detachment component is used to fix the cloth bag between the first swing component and the second swing component to prevent the cloth bag from falling off due to gravity during the filling process.

[0009] For example, at least one embodiment of this disclosure provides a bagging mechanism for probiotics and molding powders, wherein the first swing member and the second swing member both have interconnected through holes and mounting grooves, and the anti-detachment member slides through and is disposed within the through hole. The bagging mechanism for probiotics and molding powders further includes:

[0010] A roller is rotatably disposed in the mounting groove, with its outer edge protruding from the mounting groove. The roller is connected to a cam located in the through hole via a connecting rod. The cam abuts against the anti-detachment component. After the roller rotates, the cam is used to push the end of the anti-detachment component to slide out of the through hole.

[0011] For example, at least one embodiment of this disclosure provides a bagging mechanism for inoculants and molding powders, wherein the upper edge of the through hole away from the discharge cylinder has a protruding limiting groove, the anti-detachment component has a limiting sliding portion, the limiting sliding portion is slidably disposed in the limiting groove, and an elastic element is disposed between the limiting sliding portion and the end of the limiting groove, the elastic element being used to push the end of the anti-detachment component to retract into the through hole.

[0012] For example, at least one embodiment of this disclosure provides a bagging mechanism for inoculants and molding powders, wherein both the first swing member and the second swing member include:

[0013] Two swing rods are respectively swinging at both ends of the annular mounting component, and the two swing rods are connected by a reinforcing rod.

[0014] Mounting plates, two of them, are disposed on the reinforcing rod and arranged in an arrangement, each mounting plate having the through hole and the mounting groove.

[0015] For example, in at least one embodiment of this disclosure, a bagging mechanism for a probiotic or molding powder is provided, wherein the first swinging member and the second swinging member further include:

[0016] A flexible connector, the two ends of which are respectively pressed onto the two mounting plates by rubber plates, the flexible connector having a clearance hole for the passage of the anti-detachment component, and the outer edge of the roller protruding beyond the outer edge of the clearance hole.

[0017] For example, at least one embodiment of this disclosure provides a bagging mechanism for inoculants and molding powders, wherein there is a clearance space between the two mounting plates for accommodating the discharge cylinder, and the flexible connector has a pressing part in the middle for pressing the cloth bag onto the discharge cylinder.

[0018] For example, at least one embodiment of this disclosure provides a bagging mechanism for inoculants and molding powders, wherein the anti-detachment component has a plurality of uniformly arranged anti-slip protrusions at one end near the discharge cylinder, and the anti-slip protrusions are used to press the cloth bag onto the rubber plate.

[0019] For example, at least one embodiment of this disclosure provides a bagging mechanism for inoculants and molding powders, wherein the rubber plate has a plurality of relief grooves, which correspond one-to-one with the anti-slip protrusions and are used to accommodate the anti-slip protrusions.

[0020] For example, at least one embodiment of this disclosure provides a bagging mechanism for inoculants and molding powders, wherein the rubber plate is pressed onto the flexible connector by countersunk bolts that are threadedly connected to the mounting plate, the countersunk bolts on the first swing member and the second swing member are misaligned, and the end face of the nut portion of the countersunk bolt is located on the inner side of the outer wall of the rubber plate to avoid abrasion of the cloth bag.

[0021] For example, at least one embodiment of this disclosure provides a bagging mechanism for inoculants and molding powders, which further includes:

[0022] A swing drive is provided, wherein the swing drive is disposed on the first swing member and the output end of the swing drive is disposed on the second swing member, and the swing drive is used to drive the first swing member and the second swing member to swing.

[0023] The beneficial effects of the embodiments of this utility model are as follows:

[0024] In this invention, the first and second swinging components move closer together by swinging, pressing the edge of the bag opening against the outer wall of the discharge cylinder to form a sealed filling space, preventing material leakage. The swing angle is adjustable to accommodate bags of different specifications (such as diameter and thickness), improving the versatility of the mechanism. The anti-detachment component slides and presses against the bag surface, increasing friction to prevent the bag from falling due to gravity or material impact during filling. The position of the anti-detachment component can be flexibly adjusted according to the bag size, achieving multi-point uniform fixation. This is particularly suitable for filling machines that simultaneously fill bags of different heights or materials, solving the problems of bag detachment and material spillage in traditional bagging machines. The adjustable swing angle and sliding anti-detachment component adapt to various bag specifications, reducing mechanism adjustment time during production changes. The ends of the first and second swinging components press against the contact surface between the discharge cylinder and the bag, forming a sealed filling channel, reducing dust spillage and material loss.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0036] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0040] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] like Figures 1-8 As shown, it illustrates a bagging mechanism for inoculants and molding powders in one embodiment of the present invention.

[0042] In some examples, the annular mounting part 1 is set on the bagging machine, and the middle part is penetrated by the discharge cylinder of the bagging machine. The first swinging part 2 and the second swinging part 3 are respectively hinged to the two ends of the annular mounting part 1 and can swing around the hinge point. The ends away from the annular mounting part 1 can move closer or further away from each other through swinging. Several anti-detachment parts 4 are slidably installed on the inner surface of the first swinging part 2 and the second swinging part 3 and can be adjusted along the thickness direction of the swinging part.

[0043] The first swinging component 2 and the second swinging component 3 move their ends closer together, pressing the edge of the bag opening against the outer wall of the discharge cylinder to form a sealed filling space and prevent material leakage. The swing angle is adjustable to accommodate bags of different specifications (such as diameter and thickness), improving the versatility of the mechanism. The anti-detachment component 4 slides and presses against the bag surface, increasing friction to prevent the bag from falling due to gravity or material impact during filling. The position of the anti-detachment component 4 can be flexibly adjusted according to the bag size to achieve multi-point uniform fixation. This is particularly suitable for filling machines that simultaneously fill bags of different heights or materials, solving the problems of bag detachment and material spillage in traditional bagging machines. The adjustable swing angle and sliding anti-detachment component 4 adapt to various bag specifications, reducing mechanism adjustment time during production changes. The ends of the first swinging component 2 and the second swinging component 3 press against the contact surface between the discharge cylinder and the bag, forming a sealed filling channel, reducing dust spillage and material loss.

[0044] In some examples, both the first swing member 2 and the second swing member 3 are provided with interconnected through holes 201 and mounting grooves 202. During swinging, the two ends can move closer or further apart. The anti-detachment member 4 slides through the through hole 201, and its end can slide out to press against the cloth bag, thereby pressing the cloth bag onto the first swing member 2 or the second swing member 3. The roller 5 is rotatably set in the mounting groove 202, with its outer edge protruding from the groove opening. When the roller 5 rotates, it drives the cam 502 to rotate through the connecting rod 501, pushing the end of the anti-detachment member 4 to slide out of the through hole 201. The contour design of the cam 502 allows the anti-detachment member 4 to extend smoothly, avoiding impact on the cloth. After the anti-detachment member 4 slides out, it presses against the surface of the cloth bag, increasing friction to prevent the cloth bag from falling due to gravity or material impact. Multiple anti-detachment members 4 are evenly distributed, forming multi-point fixation, enhancing adaptability to materials of different weights.

[0045] The first swinging component 2 and the second swinging component 3 are pressed together with the anti-slip component 4 to seal the bag and prevent it from falling, thus improving the stability of the bag. The roller 5 rotates under the action of friction when the bag slides down, and the anti-slip component 4 is extended through the cam 502, which reduces manual operation and avoids damage to small bags caused by the use of the anti-slip component 4 when it is not necessary to use the anti-slip component 4 to prevent the bag from slipping during small packaging.

[0046] In some examples, precise control of the sliding trajectory is achieved through the limiting slide groove 203 and the limiting slide part 401, ensuring that the anti-detachment component 4 can only slide in a direction perpendicular to the axis of the discharge cylinder. This design eliminates the risk of lateral offset in traditional sliding structures, ensuring that the perpendicularity error between the end of the anti-detachment component 4 and the surface of the bag is small, and avoiding jamming of the anti-detachment component 4. When the bag slides down, the roller 5 rolls along the axis of the discharge cylinder, driving the cam 502 to rotate and push the anti-detachment component 4 out. At this time, the elastic element 6 is compressed and stores energy. When the bag is finished, the first swinging element 2 and the second swinging element 3 are released, the elastic element 6 releases energy, causing the anti-detachment component 4 to automatically retract. The cam 502 is released from the constraint on the anti-detachment component 4 and is pushed to reverse by the anti-detachment component 4. The roller 5 rolls in the opposite direction to achieve reset.

[0047] In some examples, the two swing rods 204 are welded into a portal frame by reinforcing rods 205, which increases the bending modulus of the first swing member 2 and the second swing member 3. When subjected to lateral pressure, the maximum deformation of the double-rod structure is reduced, ensuring the positioning accuracy of the anti-detachment member 4.

[0048] The double swing rods 204 form a rigid linkage through the reinforcing rods 205, reducing the swing angle deviation of the mounting plates 206 at both ends and ensuring the uniformity of the clamping force of the anti-detachment component 4 on the bag. The combined design of the double swing rods 204, reinforcing rods 205, and mounting plates 206 solves the problems of insufficient rigidity, low positioning accuracy, and inconvenient maintenance associated with traditional single-rod structures. Its innovation lies in integrating dispersed functions into a highly efficient and collaborative rigid system, which improves the overall performance of the mechanism and reduces maintenance costs, making it particularly suitable for the needs of large-scale, high-speed industrial bagging equipment.

[0049] In some examples, the flexible connector 207 is pressed against the mounting plate 206 by the rubber plate 208, forming a certain amount of compression (not less than 1 mm). This pre-tightening force allows the flexible connector 207 and the rubber plate 208 to maintain the initial sealing pressure under natural conditions, effectively preventing dust particles from entering and extending the service life of the flexible connector 207, the rubber plate 208, and the mounting plate 206.

[0050] The edge of the clearance hole 209 maintains a certain radial gap with the anti-detachment component 4. When the anti-detachment component 4 is in reciprocating motion, there is no friction between the clearance hole 209 and the anti-detachment component 4, which extends the service life of the flexible connector 207.

[0051] When the first swinging member 2 and the second swinging member 3 close rapidly, the flexible connector 207 absorbs the impact energy through viscoelastic deformation. This buffering effect protects the contact surfaces of the anti-detachment member 4 and the roller 5, reducing the wear on both.

[0052] In some examples, the clearance space 210 forms an encircling structure around the discharge cylinder through the symmetrical structure of the two mounting plates 206, ensuring that the clamping part 211 of the flexible connector 207 can act evenly on the bag. When the material falls from the discharge cylinder into the bag, the elastic wrapping of the clamping part 211 prevents dust from spilling out between the bag and the discharge cylinder during the material's descent.

[0053] In some examples, the anti-slip protrusions 402 adopt a conical structure, evenly distributed along the end faces of the anti-slip component 4, forming multiple contact points. This layout makes the contact pressure distribution more uniform. The rubber plate 208 is compressed by the protrusions, creating elastic indentations that fill the microscopic gaps between the protrusions and the fabric, increasing the anti-slip force when the material is bagged, thus reducing the risk of slippage. When the bag expands due to the filling, the elastic deformation of the rubber plate 208 can compensate for displacement deviations, ensuring that the protrusions always maintain a tight grip on the bag.

[0054] In some examples, the surface of the rubber sheet 208 has several clearance grooves 212, each corresponding to an anti-slip protrusion 402 of the anti-detachment component 4, with the groove depth matching the protrusion height. After the anti-detachment component 4 moves, the anti-slip protrusion 402 is embedded in the clearance groove 212, maintaining a slight gap between the protrusion and the edge of the groove. When the clearance groove 212 is squeezed by the anti-slip protrusion 402, the rubber material bulges outward to form a wrapping force, increasing the contact area, improving the static friction coefficient, and enhancing the anti-slip force when the material is bagged.

[0055] In some examples, countersunk bolts 213 secure the rubber sheet 208 to the mounting plate 206 via threaded connections, with the nut end face lower than the outer wall surface of the rubber sheet 208. The countersunk bolts 213 on the first swing member 2 and the second swing member 3 are arranged in an alternating pattern. The nut end face has a recess depth of 1mm, forming a protective raised layer on the rubber sheet 208, completely isolating the bolts from the cloth bag. The alternating arrangement of bolts makes the clamping force distribution on the rubber sheet 208 more uniform. Under the action of preload, the rubber material around the bolt holes expands radially, filling the bolt hole gaps and forming a secondary seal.

[0056] In some examples, the swing drive 7 is mounted on the outside of the first swing member 2, and its output end is hinged to the corresponding position of the second swing member 3. The output end of the swing drive 7 and the second swing member 3 form a linkage mechanism. When the drive is activated, it drives the first swing member 2 and the second swing member 3 to swing synchronously around the two ends of the annular mounting member 1. This ensures that the swing angle and speed of the first swing member 2 and the second swing member 3 are consistent, achieving uniform compression of the bag and avoiding sealing failure due to asynchronous swing.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
