Description

Technical Field

[0001] This utility model relates to the technical field of anti-clogging structures, and in particular to an anti-clogging structure for the waste inlet of a pre-finishing machine. Background Technology

[0002] In the industrial production process of pre-finishing machines, timely discharge of waste is a key factor in ensuring the continuous and stable operation of the equipment. The waste outlet of traditional pre-finishing machines is usually directly connected to the waste discharge pipe. During long-term use, due to the irregular shape of the waste, it is very easy for it to accumulate and clog at the waste outlet.

[0003] Existing waste disposal systems mostly rely on periodic manual cleaning or single mechanical guide devices. Manual cleaning is not only inefficient but also poses safety hazards due to operator contact with waste materials. Conventional mechanical guide structures struggle to handle blockages under complex operating conditions, especially when waste materials become compacted and sticky, significantly reducing their effectiveness. Frequent blockages can lead to production interruptions, accelerated equipment wear, and even serious consequences such as waste backflow damaging internal components of the pre-fabricated machine. Therefore, a highly efficient and reliable anti-blockage structure is urgently needed. Utility Model Content

[0016] The load-bearing block is fixedly installed on the waste discharge port, and the vibrating rod is slidably inserted into the load-bearing block.

[0017] This utility model provides a pre-finishing machine waste inlet anti-clogging structure, in which a spring support block is threadedly engaged with a vibration rod.

[0018] This utility model discloses a pre-finishing machine waste inlet anti-clogging structure, wherein two anti-loosening nuts are provided at the bottom threaded sleeve of the vibrating rod, and the anti-loosening nuts are used to support the spring support block.

[0019] This utility model discloses a pre-processing machine waste inlet anti-clogging structure, in which a positioning sleeve is provided on the load-bearing lifting block, the positioning sleeve is slidably sleeved on the vibrating lifting rod, and the positioning sleeve is in contact with the top of the spring.

[0020] This utility model discloses an anti-clogging structure for the waste inlet of a pre-finishing machine, the gate mechanism comprising:

[0021] Two mounting reference bars are symmetrically positioned at the waste discharge port.

[0022] Two swing shafts are symmetrically inserted and rotated on two opposing mounting reference bars;

[0023] Both gates are oscillatingly mounted on the mounting reference bar and fixedly connected to the swing shaft. The gate cover is installed at the waste discharge port.

[0024] The drive assembly, located at the waste outlet, is used to control the swing of the two gates.

[0026] The cylinder is fixedly installed on the exhaust port;

[0027] The drive slider is fixedly connected to the output end of the cylinder and moves up and down, positioned outside the waste discharge port.

[0028] Two drive links are oscillatingly mounted on the drive slider, and each drive link is hinged to one of the two gates.

[0031] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0032] Addressing the issue of irregularly shaped waste clogging at the waste inlet of traditional pre-finishing machines, this anti-clogging structure utilizes a vibrating motor in the vibrating discharge mechanism to generate vibration at the discharge outlet. This vibration disrupts the accumulation of waste at the outlet, preventing compaction and adhesion, effectively avoiding blockages and ensuring smooth waste discharge. Compared to existing waste discharge systems that rely on periodic manual cleaning, this structure achieves automated anti-clogging, eliminating the need for frequent manual intervention and significantly improving cleaning efficiency. Simultaneously, it avoids direct contact between operators and waste, eliminating safety hazards associated with such contact and ensuring operator safety. Conventional mechanical drainage structures struggle to address this issue. Addressing the issue of clogging under complex operating conditions, this anti-clogging structure, through the coordinated operation of a vibration discharge mechanism and a gate mechanism, can adapt to the waste discharge requirements under different operating conditions. Even in complex situations such as waste compaction and adhesion, it can ensure normal waste discharge, reducing production interruptions and equipment wear caused by clogging, extending equipment lifespan, and improving equipment stability and reliability. Because this structure effectively prevents waste clogging, it reduces serious consequences such as waste backflow damaging internal components of the pre-machine caused by clogging, thus reducing equipment maintenance frequency and costs. At the same time, it improves production efficiency, reduces economic losses caused by production interruptions, and lowers the company's operating costs. Attached Figure Description

[0039] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0040] like Figures 1 to 4 As shown, the present invention provides a pre-finishing waste inlet anti-clogging structure, comprising:

[0041] Waste discharge pipe 1 is installed on the waste discharge port of the pre-finishing machine to guide the discharge of waste materials;

[0042] Waste discharge port 11 is located at the output end of waste discharge pipe 1 and is connected to waste discharge pipe 1 for discharging waste material;

[0043] Vibrating discharge mechanism 2. It is installed on the waste discharge port 11 and is used to connect the waste discharge port 11 and the waste discharge pipe 1;

[0044] Vibration motor 21 is fixedly installed on waste discharge port 11 to provide vibration force;

[0045] Two hoisting beams 22 are symmetrically fixed on the outer wall of the waste discharge pipe 1, and each hoisting beam 22 is equipped with two sets of vibration components;

[0046] The gate mechanism 3 is installed on the waste discharge port 11 and is used to control the opening and closing state of the output end of the waste discharge port 11.

[0047] The vibration component includes:

[0048] Vibratory boom 23 is fixedly connected to lifting beam 22;

[0049] Spring support block 24 is fitted onto the bottom of vibrating rod 23;

[0050] Spring 25 is fitted onto vibrating rod 23, and the bottom end of spring 25 is supported on spring support block 24;

[0051] The load-bearing block 26 is fixedly installed on the waste discharge port 11, and the vibrating rod 23 is slidably inserted into the load-bearing block 26.

[0052] The working process and principle of the device are as follows: When the pre-processing machine starts working, the waste material moves from the waste discharge pipe 1 to the waste discharge port 11; at this time, the vibration motor 21, which is fixedly installed on the waste discharge port 11, starts and generates vibration force; the vibration force of the vibration motor 21 is transmitted to the waste discharge port 11. Since the waste discharge port 11 is slidably connected to the vibration rod 23 through the load-bearing lifting block 26, and the vibration rod 23 is fixedly connected to the lifting beam 22, which is fixed on the outer wall of the waste discharge pipe 1, the waste discharge port 11 vibrates up and down under the action of vibration force; during the vibration process, the spring 25 and the spring support block 24 play the role of buffering and assisting the vibration; the spring 25 is fitted on the vibration rod 23. The bottom is supported on the spring block 24. When the waste discharge port 11 vibrates downward, the spring 25 is compressed, storing elastic potential energy. When the waste discharge port 11 rebounds upward, the spring 25 releases elastic potential energy, assisting the waste discharge port 11 in completing the vibration action, making the vibration more stable and continuous. The gate mechanism 3 is set on the waste discharge port 11 to control the opening and closing state of the output end of the waste discharge port 11. During normal waste discharge, the gate mechanism 3 is in the open state, allowing waste to be discharged from the waste discharge port 11. When it is necessary to stop waste discharge or perform equipment maintenance, the output end of the waste discharge port 11 can be closed by controlling the gate mechanism 3 to prevent waste from continuing to be discharged. This addresses the issue that the waste discharge port of traditional pre-finishing machines is prone to irregular waste shapes. To address the issue of waste accumulation and blockage, this anti-blockage structure utilizes the vibration motor 21 of the vibration discharge mechanism 2 to provide vibration, causing the waste discharge port 11 to vibrate. This vibration disrupts the accumulation of waste at the discharge port 11, preventing compaction and adhesion, effectively avoiding blockages and ensuring smooth waste discharge. Compared to existing waste discharge systems that rely on periodic manual cleaning, this structure achieves automated anti-blockage functionality, eliminating the need for frequent manual intervention and significantly improving cleaning efficiency. Simultaneously, it avoids direct contact between operators and waste, eliminating safety hazards associated with such contact and ensuring operator safety. Conventional mechanical drainage structures struggle to handle blockages under complex working conditions. This anti-clogging structure, through the coordinated operation of the vibration discharge mechanism 2 and the gate mechanism 3, can adapt to the waste discharge requirements under different working conditions. Even in complex situations such as waste compaction and adhesion, it can ensure normal waste discharge, reducing production interruptions and equipment wear caused by clogging, extending equipment service life, and improving equipment stability and reliability. Because this structure can effectively prevent waste blockage, it reduces serious consequences such as waste backflow damaging internal components of the pre-machine caused by blockage, reducing equipment maintenance frequency and costs. At the same time, it improves production efficiency, reduces economic losses caused by production interruptions, and lowers the company's operating costs.

[0053] The spring support block 24 and the vibrating rod 23 are threaded together. This threaded design allows for easy adjustment of the initial compression of the spring 25, i.e., the spring preload, during installation or commissioning. Different preloads affect the vibration frequency and amplitude of the waste discharge port 11. By adjusting these preloads appropriately, the vibrating discharge mechanism 2 can better adapt to different types and characteristics of waste materials, improving the anti-clogging effect. For loose, easily flowing waste materials, the spring preload can be appropriately reduced, resulting in a relatively smaller vibration amplitude at the waste discharge port 11. Conversely, for waste materials that are easily compacted and adhered, the spring preload can be increased to enhance the vibration intensity of the waste discharge port 11, effectively breaking down the compacted and adhered state of the waste materials. The threaded connection is a reliable method, ensuring the connection strength and stability between the spring support block 24 and the vibrating rod 23. During the long-term vibration of the waste discharge port 11, the spring support block 24 will not easily loosen or fall off, ensuring that the spring 25 is always in the correct position and providing stable elastic support for the waste discharge port 11. This helps to improve the working stability and reliability of the entire vibrating discharge mechanism 2, reduce the occurrence of failures caused by structural loosening or damage, and reduce equipment maintenance costs and downtime. When the spring 25 suffers fatigue damage or other failures due to long-term use, since the spring support block 24 and the vibrating rod 23 are threaded together, the operator can easily unscrew the spring support block 24 from the vibrating rod 23, remove the damaged spring 25, and replace it. After replacement, the new spring 25 is then fitted onto the vibrating rod 23, and the spring support block 24 is screwed on to adjust the spring preload. This greatly simplifies the spring maintenance and replacement process and improves the maintainability of the equipment.

[0054] Two anti-detachment nuts 27 are installed at the bottom threaded sleeve of the vibrating rod 23. The anti-detachment nuts 27 are used to support the spring support block 24. During the vibration of the waste discharge port 11, the vibrating rod 23 will bear a large force, and the spring support block 24 may fall off the vibrating rod 23 under the influence of vibration. The setting of two anti-detachment nuts 27 provides reliable support and limit for the spring support block 24, effectively preventing the spring support block 24 from falling off, ensuring that the spring 25 can work normally and providing stable elastic support for the vibration of the waste discharge port 11. The presence of anti-detachment nuts 27 enhances the structural stability of the entire vibrating discharge mechanism 2. During long-term use, even under the influence of frequent vibration and complex working conditions, the anti-detachment nuts 27 can ensure the stability of the position of the spring support block 24 and the spring 25, reducing the occurrence of failures caused by structural loosening or damage, and improving the reliability and service life of the equipment. Preventing the spring support block 24 from falling off can avoid structural imbalance or failure caused by the spring 25 losing support, reducing the risk of safety accidents during equipment operation.

[0055] A positioning sleeve 28 is provided on the load-bearing lifting block 26. The positioning sleeve 28 is slidably fitted on the vibrating lifting rod 23 and is in contact with the top of the spring 25. The positioning sleeve 28 and the top of the spring 25 are in contact, providing a stable support point for the top of the spring 25. During the vibrating discharge process, the spring 25 will continuously expand and contract with the vibration of the waste discharge port 11. The presence of the positioning sleeve 28 can prevent the spring 25 from shifting or shaking during the expansion and contraction process, ensuring that the spring 25 can expand and contract in the predetermined direction and force, providing stable elastic support for the vibration of the waste discharge port 11. The positioning sleeve 28 enhances the structural stability of the entire vibrating discharge mechanism 2. During long-term use, even under the influence of frequent vibration and complex working conditions, the positioning sleeve 28 can maintain a tight fit with the top of the spring 25, reducing the occurrence of failures caused by structural loosening or damage. The presence of the positioning sleeve 28 can reduce the direct friction and collision between the spring 25 and other components, thereby reducing the noise during equipment operation. At the same time, it can also reduce the wear of the spring 25 and other related components, extend the service life of the equipment, and reduce the maintenance cost of the equipment.

[0056] like Figure 1 As shown, the gate mechanism 3 includes:

[0057] Two mounting reference bars 31 are symmetrically arranged at the output port of the waste discharge port 11;

[0058] Two swing shafts 32 are symmetrically inserted into two opposing mounting reference bars 31.

[0059] Two gates 33 are oscillatingly mounted on the mounting reference bar 31 and fixedly connected to the swing shaft 32. The gates 33 are covered at the output port of the waste discharge port 11.

[0060] A drive assembly, located on the waste outlet 11, is used to control the swing of the two gates 33;

[0061] The working process and principle of the gate mechanism 3 are as follows: When waste needs to be discharged, the drive assembly starts to work; the drive assembly applies a force to the two gates 33, causing the two gates 33 to swing outward around the swing shaft 32; as the gates 33 swing, the output port of the waste discharge port 11 gradually opens, and the waste is smoothly discharged from the waste discharge port 11 under the action of the vibration force generated by the vibrating discharge mechanism 2; when the waste is discharged or it is necessary to stop the waste discharge, the drive assembly works in the opposite direction, applying a force in opposite directions to the two gates 33, causing the two gates 33 to swing inward around the swing shaft 32; the gates 33 gradually return to their initial position, re-cover the output port of the waste discharge port 11, close the waste discharge port 11, and prevent the waste from continuing to be discharged; the gate mechanism 3 can precisely control the swing of the two gates 33 through the drive assembly. The gate 33 can be adjusted by changing the angle and position of the gate to achieve precise control over the opening and closing of the waste discharge port 11. The time and flow rate of waste discharge can be flexibly adjusted according to actual production needs, improving the automation and efficiency of production. When waste discharge port 11 is not required, the gate 33 can tightly cover the output port of waste discharge port 11, effectively preventing waste leakage. This not only avoids waste pollution of the surrounding environment but also reduces waste and lowers production costs. In special circumstances such as equipment maintenance, repair, or malfunction, closing the gate 33 can promptly stop waste discharge, preventing waste backflow from damaging internal components and protecting the safe operation of the equipment. Furthermore, closing the gate 33 before starting the equipment can prevent waste from suddenly gushing out during startup, causing equipment damage or personal injury.

[0062] like Figure 1 As shown, the driving component includes:

[0063] Cylinder 34 is fixedly installed on exhaust port 11;

[0064] The drive slider 35 is fixedly connected to the output end of the cylinder 34 and moves up and down at the outer end of the waste discharge port 11.

[0065] Two drive links 36 are oscillatingly mounted on the drive slider 35, and the two drive links 36 are respectively hinged to the two gate plates 33;

[0066] The working process and principle of the drive assembly are as follows: When the waste discharge port 11 needs to be opened for waste discharge, the cylinder 34 starts to work, and its output end pushes the drive slider 35 to move downward; as the drive slider 35 moves downward, the two drive connecting rods 36 swing accordingly; since the drive connecting rods 36 are hinged to the gate plate 33, the swing of the drive connecting rods 36 will drive the two gate plates 33 to swing outward around the swing shaft 32, thereby gradually opening the output port of the waste discharge port 11; when the drive slider 35 moves to a certain position, the gate plate 33 reaches the maximum opening angle, the waste discharge port 11 is fully opened, and the waste is smoothly discharged under the action of the vibration force generated by the vibration discharge mechanism 2; when the waste is discharged or it is necessary to stop the waste discharge, the output end of the cylinder 34 moves in the opposite direction, driving the drive slider 35 to move upward; the upward movement of the drive slider 35 causes the two drive connecting rods 36 to swing in the opposite direction, thereby driving the two gate plates 33 to swing inward around the swing shaft 32; as the drive slider 35 moves downward, the two drive connecting rods 36 swing inward around the swing shaft 32, thereby gradually opening the output port of the waste discharge port 11; when the drive slider 35 moves to a certain position, the gate plate 33 reaches the maximum opening angle, the waste discharge port 11 is fully opened, and the waste is smoothly discharged under the action of the vibration force generated by the vibration discharge mechanism 2; when the waste is discharged, or when the waste discharge needs to be stopped, the output end of the cylinder 34 moves in the opposite direction, driving the drive slider 35 to move upward; the upward movement of the drive slider 35 causes the two drive connecting rods 36 to swing in the opposite direction, thereby driving the two gate plates 33 to swing inward around the swing shaft 32; as the drive slider 35 moves downward, the two drive connecting rods 36 to swing in the opposite direction, thereby driving As the valve continues to move upward, the gate 33 gradually returns to its initial position and re-covers the waste outlet 11, closing the waste outlet 11. The cylinder 34 provides stable and precisely controllable power. Through the transmission of the drive slider 35 and the drive linkage 36, the swing angle and position of the two gates 33 can be precisely controlled, thereby achieving precise control of the opening and closing state of the waste outlet 11. This allows for flexible adjustment of the waste discharge time and flow rate according to actual production needs, improving the automation level and efficiency of production. The cylinder 34 has the characteristics of fast response and reliable operation. When it is necessary to open or close the gate 33, the cylinder 34 can react quickly, driving the drive slider 35 and the drive linkage 36 to move rapidly, so that the gate 33 opens or closes in time. This helps to reduce the waiting time during the waste discharge process, improve production efficiency, and can also quickly close the waste outlet 11 in an emergency to prevent waste backflow from damaging the equipment.

[0067] A rubber strip 37 is provided at the contact end between the gate 33 and the output port of the waste discharge port 11. The rubber strip 37 has good elasticity and sealing performance. When the gate 33 is closed, the rubber strip 37 can fit tightly against the edge of the output port of the waste discharge port 11, effectively preventing waste leakage when the waste discharge port 11 is closed, improving the sealing performance of the waste discharge system and avoiding pollution of the surrounding environment by waste. The rubber strip 37 can also play a buffering role. When the gate 33 is closed, the rubber strip 37 can absorb the impact force between the gate 33 and the edge of the output port of the waste discharge port 11, reducing the wear of the gate 33 and the waste discharge port 11, and extending the service life of the equipment. At the same time, the buffering effect can also reduce the noise generated when the gate 33 is closed and improve the working environment.

[0068] A side baffle 38 is integrally formed and bent at the edge of the gate 33; the close fit between the side baffle 38 and the side of the waste discharge port 11 further enhances the sealing effect between the gate 33 and the waste discharge port 11; when the gate 33 is closed, it can effectively prevent waste from leaking from the gap between the edge of the gate 33 and the side of the waste discharge port 11, improve the sealing performance of the waste discharge system, and avoid waste from polluting the surrounding environment; during the waste discharge process, the side baffle 38 can limit the diffusion of waste to the outside of the edge of the gate 33, guide the waste to be discharged along the center direction of the waste discharge port 11, prevent waste from overflowing into the environment around the waste discharge port 11, and keep the working area clean.

[0069] The present invention relates to a pre-finishing machine waste inlet anti-clogging structure. Its installation method, connection method, or setting method are all common mechanical methods. As long as it can achieve its beneficial effect, it can be implemented.

[0070] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
