Description

Technical Field

[0001] The present application relates to the field of material recycling and processing, and in particular to a dust-proof hopper device for destruction equipment. Background Art

[0002] Destruction equipment refers to mechanical devices used to process and destroy various materials, documents, data storage waste, and other items that are no longer needed or that pose security or privacy risks. These devices are designed to ensure that items cannot be recovered or used, thereby protecting information security, preventing information leaks, and reducing environmental pollution. Destruction equipment has a wide range of applications, including but not limited to paper documents, data storage waste, electronic devices, and chemicals.

[0003] After being destroyed, solid materials are typically in powder form or carry a large amount of powder. When the waste powder is transferred from the tool outlet to the waste bin, the motor driving the tool generates a large amount of positive airflow, which causes the waste powder in the waste bin to fly all over the interior of the destruction equipment. This causes serious pollution, creates trouble for workers to clean up, and in some cases even affects the normal operation of the equipment. Utility Model Content

[0004] In order to improve the waste collection device of the destruction equipment so as to prevent the waste powder from being blown around by the positive wind without affecting the normal transportation of the waste powder, the present application provides a dust-proof hopper device of the destruction equipment.

[0005] The dust-proof hopper device of the destruction equipment provided in this application adopts the following technical solution:

[0006] The dust-proof hopper device of the destruction equipment is placed between the waste box and the prop outlet, and includes a barrel for placing processed materials and two hinge doors symmetrically hinged to the bottom of the barrel for opening and closing the bottom of the barrel. The end of the barrel away from the hinge door is connected to the tool outlet of the destruction equipment, and the hinge door is connected to a control mechanism for controlling the opening and closing of the hinge door. An elastic compression mechanism for detecting the quality of waste in the barrel is provided on the side of the hinge door close to the inside of the barrel. A sensor electrically connected to the elastic compression mechanism is embedded in the hinge door, and the sensor is electrically connected to the control mechanism. A number of ventilation holes for dust discharge are evenly opened on the side wall of the barrel along the circumference, and the side wall of the barrel is also covered with a dust-proof cloth to prevent dust from flying.

[0007] By adopting the above technical solution, two control mechanisms respectively control the opening and closing of the two hinge doors. When the elastic compression mechanism in the barrel is subjected to pressure from the waste in the barrel, the elastic compression mechanism will transmit the pressure to the sensor. When the sensor detects that the pressure from the elastic compression mechanism reaches a predetermined value, the sensor will send a signal to the control mechanism to drive the two hinge doors to open. The purpose of opening a number of ventilation holes along the circumference of the side wall of the barrel and covering the barrel with dustproof cloth along the circumference is to prevent the dust flying due to the positive wind from the direction of the tool outlet from flying into the structure inside the destruction equipment, and at the same time, the positive wind can be discharged smoothly, thereby improving the waste dust control capability of the equipment at the outlet.

[0008] Optionally, the control mechanism includes a fixed block fixedly connected to the mounting platform of the barrel, a connecting rod hinged at one end to the fixed block, and a cylinder fixedly connected to the end of the connecting rod away from the fixed block, the cylinder and the connecting rod are coaxial, and the end of the telescopic rod of the cylinder is hinged to the side of the hinge door away from the inside of the barrel, and the cylinder is electrically connected to the sensor.

[0009] By adopting the above technical solution, when receiving the electrical signal from the sensor, the cylinder telescopic rod will open and close the hinge door by extending and contracting. The operating structure is simple and the response is fast, and it will not affect the discharge of waste.

[0010] Optionally, a compression spring is sleeved on the telescopic rod of the cylinder, and two ends of the compression spring are respectively in contact with the cylinder body of the cylinder and the hinge door, and the compression spring is always in a compressed state.

[0011] By adopting the above technical solution, the cylinder can help ensure that the hinge door is always in a tightly closed state when closing the hinge door, thereby ensuring that the positive wind will not blow the waste dust into other structures of the destruction equipment through the gap between the two hinge doors, providing compensation for the control mechanism.

[0012] Optionally, the telescopic rod of the cylinder is hinged to the middle part of the hinge door, and the telescopic length of the cylinder is greater than twice the width of the two hinge doors.

[0013] By adopting the above technical solution, the hinge door can be completely closed by cylinder drive, avoiding the situation where the two hinge doors are close to each other due to the small force, resulting in the middle of the hinge door being squeezed out of the gap when the mass of waste loaded in the barrel is too large, and eventually the waste dust is affected by the positive wind and blown out of the barrel.

[0014] Optionally, the elastic compression mechanism includes four sleeves integrally arranged near the four corners of the hinge door, four support legs respectively inserted into the sleeves, and a support plate integrally connected to the four support legs at one end away from the sleeves. Springs are connected between the four support legs and the bottom of the sleeve, and the middle of the support plate abuts against the sensor receiving end.

[0015] By adopting the above technical solution, when the support plate is subjected to the pressure of the waste, it will be displaced, and the connection between the sensor and the middle part of the support plate can better reflect the displacement distance of the support plate, thereby obtaining accurate pressure data and improving the response sensitivity of the hopper device. The main function of the spring is to help the support plate return to the center.

[0016] Optionally, the dustproof cloth is made of breathable polyester dustproof cloth.

[0017] By adopting the above technical solution, the polyester dust-proof cloth can not only effectively block waste dust, but also has good air permeability, which can more conveniently discharge the positive air discharged from the tool outlet into the barrel, thereby reducing the probability of dust flying up.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application improves the structure of the destruction equipment by adding a hopper device between the waste bin and the cutter outlet. This effectively prevents the waste discharged from the cutter outlet from being blown by the positive wind and scattered to other locations within the destruction equipment, thereby improving the waste collection efficiency and maintaining the cleanliness of the interior of the destruction equipment.

[0020] 2. This application realizes the regular discharge of waste materials entering the barrel through the combined action of the elastic compression mechanism and the control mechanism, improves the adjustability and sensitivity of the barrel's waste material release rate, and improves the overall automation performance of the equipment;

[0021] 3. In this application, a compression spring is sleeved on the telescopic rod of the cylinder to ensure that the two hinged doors at the bottom of the barrel can be completely closed, thereby improving the stability of the equipment operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The embodiments of the present application disclose a dust prevention hopper device for destruction equipment.

[0029] Reference Figure 1 The dust-proof hopper device of the destruction equipment is placed between the waste bin and the tool outlet. It is mainly used to solve the problem that the waste powder after the solid waste is decomposed is blown by the positive wind from the tool outlet and scattered to other locations inside the destruction equipment. The hopper device includes a barrel 1 whose upper opening is connected to the tool outlet, two hinged doors 2 symmetrically hinged to the bottom opening of the barrel 1, and a control mechanism 3 for controlling the opening and closing of the hinged doors 2. A sensor 4 electrically connected to the control mechanism 3 and an elastic compression mechanism 5 electrically connected to the sensor 4 are embedded in the hinged door 2. The main function of the elastic compression mechanism 5 is to carry the waste entering the barrel 1 and to feed back the quality information of the waste to the sensor 4.

[0030] The sidewalls of the barrel 1 are circumferentially provided with a plurality of ventilation holes 11 for directing positive air out of the barrel 1. A dustproof cloth is also wrapped around the sidewalls of the barrel 1 to prevent waste dust from escaping the barrel 1. This design effectively ensures the smooth discharge of positive air from the cutter outlet while preventing waste dust from being affected by the positive air flow and scattering around within the barrel 1, potentially entering various locations within the destruction equipment and becoming difficult to clean.

[0031] Preferably, the dustproof cloth is a breathable polyester dustproof cloth, which has good wear resistance and high cost performance.

[0032] In this application, because the dustproof cloth is only used to cover the outer side of the barrel 1 along the circumferential direction, and its material is existing technology, it is no longer shown separately in the drawings. Professionals in this field can determine the position and method of covering the barrel 1 with the dustproof cloth based on the description of this embodiment.

[0033] Reference Figure 2Specifically, the control mechanism 3 includes two fixed blocks 31 symmetrically mounted on the mounting platform of the barrel 1, a connecting rod 32 hinged at one end to the fixed block 31, and a cylinder 33 fixed to the end of the connecting rod 32 away from the fixed block 31. The cylinder 33 is coaxial with the connecting rod 32, and the end of the telescopic rod of the cylinder 33 is hinged to the side of the hinge door 2 away from the interior of the barrel 1. The cylinder 33 drives the hinge door 2 to rotate, thereby achieving the purpose of opening and closing the hinge door 2. The cylinder 33 is electrically connected to the sensor 4. When the sensor 4 detects that the weight on the hinge door 2 reaches a predetermined value, it sends an electrical signal to the cylinder 33 to open the hinge door 2, allowing the waste in the barrel 1 to enter the waste bin.

[0034] Reference Figure 1 and Figure 2 Furthermore, a compression spring 6 is sleeved on the telescopic rod of the cylinder 33, and the two ends of the compression spring 6 respectively abut against the cylinder body and the hinge door 2. The compression spring 6 is always in a compressed state to ensure that the hinge door 2 can be fully closed, preventing the dust in the barrel 1 from flying through the gap between the two hinge doors 2 to other locations inside the destruction device.

[0035] Reference Figure 1 and Figure 2 Furthermore, the telescopic rod of the cylinder 33 is hinged to the middle part of the hinge door 2, and the length of the telescopic rod of the cylinder 33 is greater than twice the width of the two hinge doors 2, so as to ensure that the hinge door 2 can be evenly stressed and tightly attached to the bottom of the barrel 1 when the cylinder 33 drives the hinge door 2 to open and close.

[0036] Reference Figure 3 and Figure 4 Specifically, the elastic compression mechanism 5 includes four sleeves 51 integrally mounted on the hinge door 2 near the four corners on the side away from the cylinder 33, four support legs 52 slidably mounted within the four sleeves 51, and a support plate 53 integrally connected to the four support legs 52 on the side away from the sleeves 51. A spring 54 is connected between the bottom of the support legs 52 and the bottom of the sleeve 51 to reset the support plate 53.

[0037] The sensor 4 is embedded in the hinged door 2, and the receiving end of the sensor 4 is always in contact with the middle of the support plate 53 near the sleeve 51. When the support plate 53 is displaced, the sensor 4 can convert the displacement signal of the support plate 53 into a weight value signal.

[0038] The implementation principle of the dust prevention hopper device of the destruction equipment in the embodiment of the present application is:

[0039] By opening a plurality of ventilation holes 11 on the side wall of the barrel 1 and covering the outer side wall of the barrel 1 with a dustproof cloth, the waste dust discharged from the tool outlet when the destruction equipment is working will not be affected by the positive wind and fly to other locations inside the destruction equipment.

[0040] At the same time, when the support plate 53 is subjected to the pressure of the waste material, it transmits a pressure signal to the sensor 4. When the pressure reaches a predetermined value, the sensor 4 sends an electrical signal to the cylinder 33, driving the cylinder 33 to open the hinged door 2. The design of the elastic compression mechanism 5 and the control mechanism 3 can automatically discharge the waste material dust in the barrel 1, improving the automation level of the equipment.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
