A centralized dust removal device for a shoe-making workshop

Abstract

The present invention relates to a centralized dust removal device for a shoe-making workshop, which includes a workbench. A work hood is arranged at the upper end of the workbench, and a collection module is installed at the rear end of the workbench. The collection module is connected to a suction module through a connecting hose. The present invention can solve the problems in the prior art that when polishing and shaping the soles of shoes using polishing equipment, most of the fine particle dander and fine dust generated during polishing are recovered by means of external bag filtration of the machine body.

Moreover, the bag filtration equipment is mainly used for large-scale dust suction in the workshop and is difficult to perform targeted dust removal and absorption on the polishing machine, resulting in partial overflow of the fine particles generated by the polishing machine and being accidentally inhaled by personnel, causing potential health hazards to the personnel and having a low efficiency in effectively removing the fine particles generated in the polishing machine, etc.

Description

Technical Field

[0001] The present invention relates to the technical field related to shoe manufacturing, and particularly relates to a centralized dust removal device for a shoe manufacturing workshop. Background Art

[0002] The emergence of shoes is inseparable from the natural environment and human wisdom. In ancient times, due to the unevenness of the land and the extreme cold and heat of the climate, humans instinctively wanted to protect their feet, so shoes appeared: simple animal skins and leaves wrapped around the feet became the earliest shoes in human history. The literature preserved by ancient humans can still provide us with a wonderful history of shoes. Nowadays, most shoes are made of leather or fabric. During the shoe manufacturing process, the surface of the shoe sole needs to be polished to make the surface of the shoe sole smoother and more comfortable to wear.

[0003] In the prior art, polishing equipment is usually used to polish and shape the shoe sole. When recycling the fine particle skin debris and fine dust generated by polishing, an external cloth bag filtration method of the machine body is mostly adopted. The distance between the cloth bag filtration equipment and the polishing machine is relatively long, making it difficult to timely suck the generated fine particles. Moreover, the cloth bag filtration equipment is mainly used for large-scale dust suction in the workshop and is difficult to perform targeted dust removal and absorption on the polishing machine, resulting in some of the fine particles generated by the polishing machine overflowing and being accidentally inhaled by personnel, triggering potential health hazards for personnel, and the efficiency of effectively removing dust from the fine particles generated by the polishing machine is relatively low.

[0004] Therefore, there is an urgent need for a centralized dust removal device for a shoe manufacturing workshop to solve the above existing defects. Summary of the Invention

[0005] I. Technical Solution

[0006] To achieve the above object, the present invention provides the following technical solution: A centralized dust removal device for a shoe manufacturing workshop, including a workbench, a work cover is arranged at the upper end of the workbench, a collection module is installed at the rear end of the workbench, and the collection module is connected to an air suction module through a connecting hose.

[0007] The work cover includes an arc-shaped frame, a rotating shaft, a side panel assembly, and a sealing cover assembly. An arc-shaped frame is installed on each side of the upper end of the workbench. The lower end of the side panel assembly located outside the arc-shaped frame is installed on the rotating shaft, and the rotating shaft is rotatably arranged on an ear seat. The ear seat is installed on the workbench. An arc-shaped groove is formed on the arc-shaped frame, and a sealing cover assembly is slidably arranged between the arc-shaped grooves.

[0008] The collecting module includes a conveying frame, a connecting component, a filtering component, an output pipe and a telescopic pipe. Connecting components are symmetrically arranged at the left and right ends of the conveying frame, and the connecting components control the flow of gas inside the conveying frame. The filtering component located inside the connecting components is installed inside the conveying frame, and the filtering component performs multiple filtrations on the passing dusty gas. An output pipe is connected and installed at the rear end of the middle part of the conveying frame, and a telescopic pipe is connected between the conveying frame and the side panel component. Since the position of the side panel component is adjustable while the position of the conveying frame remains unchanged, the telescopic pipe ensures the smooth flow of gas between the two.

[0009] The air suction module includes a connecting frame, a U-shaped filter element, an air suction pump and an inlet hole. A discharge port is opened in the middle of the rear end of the connecting frame. The U-shaped filter element located in front of the discharge port is installed inside the connecting frame, and the U-shaped filter element further filters the passing gas. An air suction pump is installed in the middle of the discharge port. Inlet holes are evenly opened at the front end of the connecting frame. A connecting hose is connected and installed between the opened inlet hole and the output pipe. The unused inlet holes are blocked by blocking blocks. Appropriate numbers of workbenches can be selected according to requirements and corresponding work covers are equipped. Subsequently, the opened inlet holes are connected to the output pipe through the connecting hose, and the unused inlet holes are blocked and sealed by the blocking blocks.

[0010] The present invention adopts the design concept of integrating a cover and air suction, reducing the overflow area of dust and fundamentally solving the problem of dust diffusion. Coupled with multi-directional synchronous air suction, the suction rate of dusty gas is improved and the dust content rate on the surface of the workbench is reduced.

[0011] As described above, the side panel component includes a side panel, a centralized cavity, a dust inlet, an arc-shaped cavity and an arc-shaped plate. A centralized cavity is opened on the back of the side panel. A dust inlet is opened on the side panel, and the dust inlet, the centralized cavity and the arc-shaped cavity opened on the side panel are connected and communicated with each other. An arc-shaped plate is embedded in the arc-shaped cavity.

[0012] As described above, the sealing cover component includes a sliding plate, a sealing cloth and an output port. The sliding plate is slidably arranged between the arc-shaped grooves. A sealing cloth is connected between adjacent sliding plates. The sealing cloth has the functions of elasticity and airtightness. A conveying cavity is opened inside the sliding plate. An input hole is opened on the end face of the sliding plate facing the workbench, and the input hole is communicated with the conveying cavity. Output ports are symmetrically connected and installed at the left and right ends of the conveying cavity. The middle part of the output port is an elastic telescopic structure, and the output port is connected and matched with the arc-shaped plate.

[0013] As described above, the output port is composed of an inner cylinder and an outer cylinder which are slidably sleeved with each other, and a built-in spring is connected between the inner cylinder and the outer cylinder. The built-in spring plays a role in resetting. Corresponding holes are evenly opened on the arc-shaped plate, and the positions of the corresponding holes and the output port are corresponding. When there is no corresponding hole embedded in the current output port, the output port serves as the air suction port structure for the side dusty gas, thereby sucking out the dusty gas.

[0014] As mentioned above, an openable sealing cover is provided at the upper end of the conveying frame. When the filter assembly intercepts a lot of dust and causes accumulation, the sealing cover is opened to centrally clean and transport the dust accumulated inside the conveying frame.

[0015] As mentioned above, a telescopic tube is installed between the conveying frame and the arc-shaped cavity, and the end of the telescopic tube in contact with the conveying frame is located on the outside of the connecting component. The setting of this positional relationship ensures that the gas must pass through the position of the connecting component when passing through the conveying frame, and ensures that the connecting component controls whether the gas inside the conveying frame flows.

[0016] As mentioned above, the connecting component includes a connecting piece and a driving motor. The connecting piece is rotatably arranged inside the conveying frame. A connecting hole is opened through the inside of the connecting piece. One end of the connecting piece is connected to the end of the rotating shaft, and the other end of the connecting piece is connected to the output shaft of the driving motor. The driving motor is installed on the outer wall of the conveying frame through a motor seat.

[0017] As mentioned above, the filter assembly is composed of multiple groups of filter screens, and the hole diameters of the filter screens arranged from the outside to the inside gradually decrease. Different hole diameters can intercept different volumes of dust.

[0018] 2. Beneficial Effects

[0019] 1. The centralized dust removal device for a shoemaking workshop described in the present invention adopts a design concept of an integrated cover body and air suction, so that fine particles can be absorbed in time when they are generated, reducing the possibility of dust spillage, solving the dust diffusion problem from the root, and coordinating with multi-directional synchronous air suction to improve the dust-containing gas suction rate. The present invention can simultaneously perform synchronous air suction treatment on multiple groups of polishing workbenches, and air suction treatment can be performed by adding only one connecting hose.

[0020] 2. The centralized dust removal device for a shoemaking workshop described in the present invention has a working hood that specifically covers the periphery and the upper end of the workbench by covering it at close range, thereby providing sufficient space for processing and taking and placing, and increasing the hood structure, thereby greatly reducing the possibility of dust particle diffusion. The side panel assembly and the sealing cover assembly are installed in an expandable and closable manner, thereby providing sufficient space during the installation of the polishing equipment and a dust gathering area during subsequent polishing. Compared with dust scattered in the workshop, the hood structure in a small area is conducive to the timely absorption of fine particles.

[0021] 3. In the centralized dust collection device for a shoe-making workshop according to the present invention, a design concept of structural linkage is adopted between the working hood and the collection module. Only when the side panel assembly is erected and forms a hood structure with the sealing hood assembly, will the inside of the conveying frame be in a ventilated state. When the side panel assembly lies flat (initial position), sufficient installation space is provided for the polishing equipment, and at this time, the inside of the conveying frame is blocked by the connecting component, so that air suction does not occur at the dust inlet position, avoiding the influence of air suction on the normal installation of the polishing equipment.

[0031] Embodiments of the present invention will be described below with reference to the drawings. During this process, to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0032] In addition, the terms used below are defined based on the functions in the present invention and may vary according to the intentions or conventions of users and operators. Therefore, these terms are defined based on the entire content of this specification.

[0033] As Figures 1 to 8As shown in the figure, a centralized dust removal device for a shoe-making workshop includes a workbench 1. A work cover 2 is arranged at the upper end of the workbench 1. A collection module 3 is installed at the rear end of the workbench 1. The collection module 3 is connected to an air suction module 5 through a connecting hose 4.

[0034] The work cover 2 includes an arc-shaped frame 21, a rotating shaft 22, a side panel assembly 23, and a sealing cover assembly 24. An arc-shaped frame 21 is installed on each of the left and right sides of the upper end of the workbench 1. The lower end of the side panel assembly 23 located outside the arc-shaped frame 21 is installed on the rotating shaft 22. The rotating shaft 22 is rotatably arranged on an ear seat, and the ear seat is installed on the workbench 1. An arc-shaped groove is provided on the arc-shaped frame 21, and a sealing cover assembly 24 is slidably arranged between the arc-shaped grooves.

[0035] The collection module 3 includes a conveying frame 31, a communication component 32, a filtering component 33, an output pipe 34, and a telescopic pipe 35. Communication components 32 are symmetrically arranged at the left and right ends of the conveying frame 31. The communication component 32 controls the flow of gas inside the conveying frame 31. The filtering component 33 located inside the communication component 32 is installed inside the conveying frame 31. The filtering component 33 performs multiple filtrations on the passing dust-containing gas. An output pipe 34 is connected and installed at the middle rear end of the conveying frame 31. A telescopic pipe 35 is connected between the conveying frame 31 and the side panel assembly 23. Since the position of the side panel assembly 23 is adjustable while the position of the conveying frame 31 remains unchanged, the telescopic pipe 35 ensures the smooth flow of gas between the two.

[0036] The air suction module 5 includes a connection frame 51, a U-shaped filter element 52, an air suction pump 53, and an inlet hole 54. A discharge port is provided in the middle of the rear end of the connection frame 51. The U-shaped filter element 52 located in front of the discharge port is installed inside the connection frame 51. The U-shaped filter element 52 further filters the passing gas. An air suction pump 53 is installed in the middle of the discharge port. Inlet holes 54 are evenly provided at the front end of the connection frame 51. A connecting hose 4 is connected and installed between the opened inlet hole 54 and the output pipe 34. The unopened inlet hole 54 is blocked by a blocking block 6. An appropriate number of workbenches 1 can be selected according to requirements, and corresponding work covers 2 are equipped. Subsequently, the opened inlet hole 54 is connected to the output pipe 34 through the connecting hose 4. The unrequired inlet holes 54 are blocked and sealed by the blocking block 6.

[0037] Specifically, install the workbench 1 at a designated position in the workshop, install the existing polishing equipment in the middle of the workbench 1, select an appropriate number of workbenches 1 for installation according to requirements. After the polishing equipment is installed, drive the side panel assembly 23 to adjust the angle upward until it stands up and fits against the outer side of the arc-shaped frame 21 by rotating the rotating shaft 22. Then, pull the sealing cover assembly 24 forward to cover the upper end of the arc-shaped frame 21 (select the covered area according to the volume of the polishing equipment and the space for placing the workpiece). The pulled sealing cover assembly 24 and the side panel assembly 23 form a full or semi-sealed cover body. At the same time as the side panel assembly 23 stands up, the rotated communication assembly 32 makes the inside of the connection frame 51 form a communication relationship, and the internal cavity structures of the side panel assembly 23 and the sealing cover assembly 24 form a communication relationship. At this time, the dust in the cover body structure can be sucked into the side panel assembly 23 and the sealing cover assembly 24 respectively through the air suction of the air suction pump 53. After multiple filtering interceptions by the filtering assembly 33 and the U-shaped filter element 52, dust removal treatment is carried out. When the side panel assembly 23 and the sealing cover assembly 24 are in the initial position, the workbench 1 is in a completely exposed state, which is conducive to the installation of the polishing equipment. Moreover, the communication assembly 32 intercepts and blocks the gas inside the conveying frame 31, so that the surface of the side panel assembly 23 will not form an air suction state, avoiding the influence of air suction on the installation of the polishing equipment. The present invention adopts the design concept of integrating the cover body and air suction, reducing the overflow area of dust and fundamentally solving the problem of dust diffusion. Coupled with multi-directional synchronous air suction, the suction rate of the dust-containing gas is improved, and the dust content rate on the surface of the workbench 1 is reduced.

[0038] In another embodiment provided by the present invention, further, the side panel assembly 23 includes a side panel 231, a central cavity 232, a dust inlet 233, an arc-shaped cavity 234, and an arc-shaped plate 235. A central cavity 232 is provided on the back of the side panel 231, a dust inlet 233 is provided on the side panel 231, and the dust inlet 233, the central cavity 232, and the arc-shaped cavity 234 provided on the side panel 231 are connected and communicated with each other. An arc-shaped plate 235 is embedded in the arc-shaped cavity 234.

[0039] Further, the seal cover assembly 24 includes a sliding plate 241, a sealing cloth 242, and an output port 243. The sliding plate 241 is slidably disposed between the arc-shaped grooves. The sealing cloth 242 is connected between adjacent sliding plates 241. The sealing cloth 242 has the functions of elasticity and airtightness. A conveying cavity is formed inside the sliding plate 241. An input hole is formed on one end face of the sliding plate 241 facing the workbench 1. The input hole is communicated with the conveying cavity. Output ports 243 are symmetrically communicated and installed at the left and right ends of the conveying cavity. The middle part of the output port 243 is an elastic telescopic structure. The output port 243 is cooperatively connected with the arc-shaped plate 235. The output port 243 is composed of an inner cylinder and an outer cylinder that are slidably sleeved with each other, and a built-in spring is connected between the inner cylinder and the outer cylinder. The built-in spring plays a role in resetting. Corresponding holes are evenly formed on the arc-shaped plate 235, and the positions of the corresponding holes correspond to those of the output ports 243. When there is no corresponding hole embedded in the current output port 243, the output port 243 at this time serves as the side dust-containing gas suction port structure, thereby sucking out the dust-containing gas.

[0040] Specifically, the rotation of the rotating shaft 22 drives the side panel 231 to adjust the angle upward until it stands up and fits against the outer side surface of the arc-shaped frame 21. Then, the seal cover assembly 24 is pulled forward. During the pulling process, the position of the pulled and unfolded seal cover assembly 24 is locked by the clamping connection between the output port 243 and the corresponding hole. Since the middle part of the output port 243 is an elastic telescopic structure, when the seal cover assembly 24 does not meet the required unfolded area, only by pulling forward forcefully can the output port 243 be extruded out of the current corresponding hole and moved to the next corresponding hole until the seal cover assembly 24 reaches the required unfolded area and is just unfolded. At this time, a communication state is formed among the dust inlet 233, the central cavity 232, the arc-shaped cavity 234, the conveying cavity, and the input hole. The unfolded seal cover assembly 24 and the side panel 231 form a full or semi-sealed cover body, providing a space for dust removal during the polishing process.

[0041] Further, an openable seal cover is provided at the upper end of the conveying frame 31. When a large amount of dust is intercepted by the filter assembly 33 and accumulates, the seal cover is opened, and the dust accumulated inside the conveying frame 31 is centrally cleaned and transported. A telescopic pipe 35 is communicated and installed between the conveying frame 31 and the arc-shaped cavity 234, and the end of the telescopic pipe 35 in contact with the conveying frame 31 is located outside the communication assembly 32. This positional relationship setting ensures that the gas must pass through the position of the communication assembly 32 when passing through the conveying frame 31, ensuring that the communication assembly 32 controls whether the gas inside the conveying frame 31 flows. The filter assembly 33 is composed of multiple groups of filter meshes, and the hole diameters of the filter meshes arranged from the outside to the inside gradually decrease, and different hole diameters intercept dust of different volumes.

[0042] Further, the connecting component 32 includes a connecting member 321 and a driving motor 322. The connecting member 321 is rotatably arranged inside the conveying frame 31. A connecting hole is formed through the inside of the connecting member 321. One end of the connecting member 321 is connected to the end of the rotating shaft 22, and the other end of the connecting member 321 is connected to the output shaft of the driving motor 322. The driving motor 322 is mounted on the outer side wall of the conveying frame 31 through a motor base.

[0043] Specifically, the driving motor 322 drives the connecting member 321 and the rotating shaft 22 to rotate synchronously, thereby driving the side panel assembly 23 to adjust its angle upward until it stands up. At this time, the side panel assembly 23 fits against the outer side of the arc-shaped frame 21. Subsequently, the sealing cover assembly 24 is pulled forward to cover the upper end of the arc-shaped frame 21. The pulled sealing cover assembly 24 and the side panel assembly 23 form a full or semi-sealing cover body. At the same time, a through-connection relationship is formed between the synchronously rotating connecting member 321 and the conveying frame 31 (the connecting hole is in through-connection with the conveying frame 31).

[0044] Working process:

[0045] Install the workbench 1 at a designated position in the workshop, install the existing polishing equipment in the middle of the workbench 1, and select an appropriate number of workbenches 1 for installation according to requirements;

[0046] After the polishing equipment is installed, the driving motor 322 drives the connecting member 321 and the rotating shaft 22 to rotate synchronously, thereby driving the side panel assembly 23 to adjust its angle upward until it stands up and fits against the outer side of the arc-shaped frame 21. Subsequently, the sealing cover assembly 24 is pulled forward. The unfolded sealing cover assembly 24 and the side panel assembly 23 form a full or semi-sealing cover body. While the side panel assembly 23 stands up, a connection relationship is formed between the rotated connecting member 321 and the inside of the connection frame 51, and a connection relationship is formed between the internal cavity structures of the side panel assembly 23 and the sealing cover assembly 24 and the conveying frame 31 and the connection frame 51. Through the air suction of the air suction pump 53, the dust in the cover body structure is respectively sucked into the side panel assembly 23 and the sealing cover assembly 24, and finally collected in the conveying frame 31. The dust-containing substances in the gas are intercepted by multiple filtrations through the filter component 33 and the U-shaped filter element 52, thereby performing dust removal treatment, and the purified gas is discharged.

[0047] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
