[0001] The utility model relates to an anti-bridging device for a batching machine, belonging to the technical field of batching machines. Background Art

[0002] Currently, material bridging is a common and troublesome problem in material handling. Bridging prevents the material from flowing smoothly within the barrel, thus affecting production efficiency and product quality.

[0003] After searching the prior art, we discovered Chinese Patent Publication No. CN213860604U, which discloses an anti-bridging plastic twin-screw extruder. This patent uses an air hammer to prevent material bridging. However, during use, it was discovered that the impact force of the air hammer can cause significant mechanical stress on the equipment, increasing wear on certain components and increasing maintenance frequency and costs. Furthermore, the air hammer generates a high level of impact noise during operation, potentially causing excessive noise levels in the operating environment and impacting the operator's work and health. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a bridging prevention device for a batching machine, which can effectively solve the material bridging phenomenon and reduce equipment wear.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a batching machine anti-bridging device, comprising at least one barrel, wherein,

[0006] The barrel is provided with a feed inlet at the top and a discharge outlet at the bottom;

[0007] The barrel is provided with a reciprocating bridge breaking mechanism and a rotating bridge breaking mechanism;

[0008] The rotating bridge breaking mechanism comprises:

[0009] A rotary drive source, the rotary drive source being fixedly mounted on the outside of the barrel, the rotary drive source being provided with an output shaft, the output shaft extending through the outer wall of the barrel into the interior of the barrel;

[0010] A bridge-breaking rod, the bridge-breaking rod being fixed to the rotating end of the output shaft of the rotary drive source and being located above the discharge port;

[0011] The reciprocating bridge-breaking mechanism comprises:

[0012] A reciprocating bridge-breaking driving member, the reciprocating bridge-breaking driving member is vertically installed inside the barrel, and the reciprocating bridge-breaking driving member is provided with a telescopic rod suitable for reciprocating along the axial direction of the barrel;

[0013] A bridge-breaking plate is installed at the lower end of the telescopic rod of the reciprocating bridge-breaking driving member.

[0014] Furthermore, a pair of the bridge-breaking rods is provided, and the pair of the bridge-breaking rods are vertically staggered and installed on the rotating end of the output shaft of the rotary drive source.

[0015] Furthermore, a specific type of rotational drive source is provided, wherein the rotational drive source is a motor.

[0016] Furthermore, the reciprocating bridge-breaking mechanism further comprises:

[0017] A limiting plate, the limiting plate is installed in the barrel and is provided with a limiting protrusion;

[0018] The broken bridge plate is provided with a waist-shaped groove that matches the limiting protrusion;

[0019] The limiting protrusion is slidably arranged in the waist-shaped groove, and the limiting protrusion is suitable for limiting the moving range of the bridge breaking plate.

[0020] Furthermore, a specific type of reciprocating bridge-breaking driving member is provided, wherein the reciprocating bridge-breaking driving member is a cylinder.

[0025] By adopting the above technical solution, the utility model has the following beneficial effects:

[0026] In this utility model, material first enters the barrel through the feed port located above it. At this point, a rotary drive source rotates the bridge-breaking rod above the discharge port, while a reciprocating bridge-breaking drive element simultaneously reciprocates the bridge-breaking plate axially within the barrel.

This significantly improves the efficiency of the batching machine.

[0028] In summary, the present invention effectively solves the problem of poor material discharge caused by material bridging by introducing a combination of reciprocating and rotary bridge breaking methods into the batching machine. This not only significantly improves the batching machine's operating efficiency, but also significantly reduces equipment wear and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 This is a schematic diagram of the three-dimensional structure of the anti-bridging device of the batching machine of the present invention;

[0030] Figure 2 It is a partial cross-sectional perspective view of the anti-bridging device of the batching machine of the present invention. DETAILED DESCRIPTION

[0031] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0032] like Figure 1-2 As shown, a batching machine anti-bridging device includes four barrels 1, wherein:

[0033] The upper part of the barrel 1 is provided with a feed port 11 and the bottom is provided with a discharge port 12;

[0034] The barrel 1 is provided with a reciprocating bridge breaking mechanism and a rotating bridge breaking mechanism;

[0035] The rotating bridge breaking mechanism includes:

[0036] A rotary drive source 21 is fixedly mounted on the outside of the barrel 1 and is provided with an output shaft that passes through the outer wall of the barrel 1 and extends into the interior of the barrel 1;

[0037] The bridge-breaking rod 22 is fixed to the rotating end of the output shaft of the rotary drive source 21 and is located above the discharge port 12;

[0038] The reciprocating bridge-breaking mechanism includes:

[0039] The reciprocating bridge-breaking driving member 31 is vertically installed inside the barrel 1 and is provided with a telescopic rod 311 adapted to reciprocate along the axial direction of the barrel 1;

[0040] The bridge breaking plate 32 is installed at the lower end of the telescopic rod 311 of the reciprocating bridge breaking driving member 31.

[0041] In this embodiment, if Figure 1-2 As shown, the material first enters the barrel 1 through the feed port 11 above it. At this point, the rotary drive source 21 drives the bridge-breaking rod 22 to rotate above the discharge port 12, while the reciprocating bridge-breaking driver 31 drives the bridge-breaking plate 32 to reciprocate axially within the barrel 1. The combination of these two bridge-breaking methods effectively disrupts and breaks material bridges from different directions and angles, ensuring smooth material discharge and preventing bridging. This significantly improves the batching machine's operating efficiency.

[0042] Specifically, such as Figure 1-2 As shown, a pair of bridge-breaking rods 22 are provided, and the pair of bridge-breaking rods 22 are vertically and staggeredly installed on the rotating end of the output shaft of the rotary drive source 21.

[0043] Specifically, such as Figure 1-2 As shown, the rotation drive source 21 is a motor.

[0044] In this embodiment, if Figure 1-2 As shown, when the motor is started as the rotational drive source 21, the output shaft drives the bridge-breaking rod 22 to rotate around its axis, ensuring that the bridge-breaking rod 22 can cover a larger area during rotation, thereby preventing the material from bridging in the barrel 1. The rotational drive source 21 is a motor, which can be precisely controlled by a motor inverter. By adjusting the speed and rotation direction of the motor, the working efficiency of the bridge-breaking rod 22 can be further improved to adapt to the characteristics and processing requirements of different materials. In addition, the shape of the bridge-breaking rod 22 can be designed to be spiral to enhance the stirring and bridge-breaking effects of the material. The rotational drive source 21 can also adopt other types of rotational drive devices, such as a hydraulic motor or a pneumatic motor.

[0045] Specifically, such as Figure 2 As shown, the reciprocating bridge-breaking mechanism also includes:

[0046] The limiting plate 33 is installed in the barrel 1 and is provided with a limiting protrusion;

[0047] The broken bridge plate 32 is provided with a waist-shaped groove that matches the limiting protrusion;

[0048] The limiting protrusion is slidably arranged in the waist-shaped groove, and the limiting protrusion is suitable for limiting the movement range of the bridge breaking plate 32.

[0049] Specifically, such as Figure 2 As shown, the reciprocating bridge-breaking driving member 31 is a cylinder.

[0050] In this embodiment, if Figure 2As shown, the reciprocating bridge-breaking driver 31 is also mounted within the barrel 1 via a limit plate 33. The limit plate 33 is secured to the inner wall of the barrel 1 at an appropriate location within the barrel 1. Its primary function is to restrict and guide the movement of the bridge-breaking plate 32. The bridge-breaking plate 32 is provided with a waist-shaped groove that mates with a limit projection. The limit projection slides within the waist-shaped groove, thereby limiting the range of movement of the bridge-breaking plate 32. This allows the bridge-breaking plate 32 to maintain a stable trajectory during its reciprocating motion, preventing malfunctions caused by deviation or jamming. The telescopic rod 311 of the reciprocating bridge-breaking driver 31 is hingedly connected to the bridge-breaking plate 32.

[0051] Driven by the reciprocating bridge-breaking driver 31, the bridge-breaking plate 32 reciprocates along the axial direction of the barrel 1. The cylinder controls the expansion and contraction of the telescopic rod 311 by the flow of compressed air, thereby driving the bridge-breaking plate 32 up and down. This up and down movement of the bridge-breaking plate 32 not only effectively breaks up the material but also prevents it from clogging above the discharge port 12, ensuring uniform discharge of material from the barrel 1.

[0052] In addition, the cylinder can also be selected according to actual needs, such as using electric push rods or hydraulic cylinders to replace the cylinder to adapt to different working environments.

[0053] Specifically, such as Figure 2 As shown, a plurality of through holes 321 are provided on the bridge breaking plate 32 .

[0054] In this embodiment, if Figure 2 As shown, the through holes 321 are primarily designed to reduce the material's resistance to the bridge-breaking plate 32 during its reciprocating motion, thereby improving the plate's efficiency. By providing the through holes 321 in the bridge-breaking plate 32, material can partially pass through these holes, preventing material accumulation and significant resistance during its movement. This ensures that the bridge-breaking plate 32, driven by the reciprocating bridge-breaking drive 31, can smoothly reciprocate along the axial direction of the barrel 1. The through holes 321 also promote uniform material distribution and flow. This helps prevent material from forming dead spots or accumulating within the barrel 1, ensuring smooth discharge from the discharge port 12. Furthermore, the design of the through holes 321 reduces the weight of the bridge-breaking plate 32, lowering the energy consumption of the entire reciprocating bridge-breaking mechanism and improving the overall efficiency of the device. In other possible embodiments, the shape and arrangement of the through holes 321 can be adjusted to meet specific needs. For example, the through holes can be designed as circular, elliptical, or other geometric shapes.

[0055] Specifically, such as Figure 2 As shown, there are four barrels 1, which are arranged in a matrix, forming a two-row and two-column T-shaped arrangement structure.

[0056] In this embodiment, if Figure 2 As shown, the arrangement of the barrels 1 employs a design in which four barrels 1 are arranged in a matrix configuration, with two rows and two columns in a "T-shaped" configuration. This effectively utilizes space. Furthermore, the "T-shaped" configuration ensures that each barrel 1 can be operated independently, reducing the possibility of material interference between barrels 1.

[0057] During operation, each barrel (1) can independently control feeding and discharging operations according to production needs, and can be equipped with different bridge-breaking mechanisms to accommodate different types of materials. For example, when certain materials are prone to bridging, the bridge-breaking device in that barrel (1) can be activated independently, while other barrels (1) can continue to operate normally without being affected. This independent control capability makes the overall operation of the equipment more flexible and efficient.

[0058] Specifically, such as Figure 2 As shown, the overall structure of the barrel 1 is wide at the top and narrow at the bottom, with the upper part being a square cylinder with a uniform cross-section, and the lower part being a square cone structure with a gradually decreasing cross-sectional area, and the discharge port 12 is arranged at the bottom.

[0059] In this embodiment, if Figure 2 As shown, the overall structure of the barrel 1 is designed to be wide at the top and narrow at the bottom, with the upper part being a square cylinder with a uniform cross-section and the lower part being a square cone structure with a gradually decreasing cross-sectional area. This can effectively improve the fluidity of the material and prevent the material from accumulating or being retained in the barrel 1. Specifically, the uniform cross-sectional square cylinder at the top provides sufficient volume for storing and temporarily accommodating a large amount of material. The cross-sectional area of the lower square cone structure gradually decreases. This conical design can naturally guide the material downward under the action of gravity, prompting the material to flow toward the discharge port 12. At the same time, as the cross-sectional area decreases, the material will gradually compress during the flow process, which helps to prevent the material from being blocked at the discharge port 12. Under the action of gravity, the material can be discharged smoothly through the discharge port 12. In addition, the coordinated use of the two internal bridge-breaking methods can effectively prevent the material from forming bridges in the barrel 1 regardless of the fluidity of the material, ensuring the normal operation of the equipment. In other possible embodiments, the geometric shape and size of the barrel 1 can be adjusted according to the characteristics of different materials and specific application requirements. For example, for materials with particularly poor fluidity, the taper of the square cone structure can be further increased to enhance the sliding and discharge effects of the material.

[0060] Specifically, such as Figure 1-2 As shown, an observation window 13 is provided on the side wall of the barrel 1. The observation window 13 is oblong, extends along the height direction of the barrel 1, and is sealed to the side wall of the barrel 1.

[0061] In this embodiment, if Figure 1-2As shown, the primary purpose of the observation window 13 is to facilitate real-time monitoring of the material status within the barrel 1 by the operator, ensuring smooth production. Specifically, the oblong design and longitudinal layout of the observation window 13 provide a large viewing area, allowing the operator to observe the material inside the barrel 1 from various angles. Through the observation window 13, the operator can promptly detect problems such as material bridging, accumulation, or poor flow, and take appropriate measures to address them. Furthermore, the sealed connection design of the observation window 13 ensures that the material inside the barrel 1 does not leak out during observation, while also preventing gases or impurities from the external environment from entering the barrel 1, maintaining the purity of the material and the safety of the production environment. In actual use, the observation window 13 not only monitors the material status but also serves to check the operation of the bridge breaking mechanism. For example, the operator can observe the rotation of the bridge breaking rod 22 and the reciprocating motion of the bridge breaking plate 32 through the observation window 13, ensuring the proper functioning of these devices. The material of the observation window 13 can be selected from a highly transparent, wear-resistant, and corrosion-resistant material, such as tempered glass or plexiglass, to ensure its stability and reliability during long-term use.

[0062] In some embodiments, the number of observation windows 13 is not limited to one and can be set according to specific needs.

[0063] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific 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 in the scope of protection of the present invention.
