Description

Technical Field

[0001] The invention relates to the technical field of film-coated filter material production, and in particular to a film-coated filter material production device which is convenient for fixing the film-coated filter material. Background Art

[0002] The coated filter material is made of polytetrafluoroethylene, which is expanded into a PTFE film with microporous properties. The PTFE film is laminated on a substrate such as glass fiber cloth to form a filter material. The coated filter material has the characteristics of high peel strength, large air permeability, small resistance, and concentrated and uniform pore size distribution. It can quickly and effectively intercept ultrafine dust, so it is widely used in industrial dust filtration and material recovery. The production of coated filter material mainly adopts the hot pressing composite process, that is, the PTFE film and the glass fiber cloth are interlocked by hot pressing. The composite coated filter material is wound on the material roller. When the winding length reaches a certain value, the production equipment must be shut down and a new material roller or barrel must be replaced for winding. Therefore, it is necessary to shut down and start up repeatedly, which is easy to cause loss of production equipment and low production efficiency.

[0054] like Figure 2-9 As shown, the present invention provides a membrane filter material production device that is convenient for fixing membrane filter materials, including a feeding mechanism for continuously feeding PTFE film and glass fiber cloth, a compounding mechanism for hot pressing and compounding PTFE film and glass fiber cloth, a winding mechanism for winding the compounded membrane filter material, and a temporary material storage mechanism arranged between the winding mechanism and the compounding mechanism. These are all prior arts and will not be described in detail here.

[0055] The winding mechanism includes a support plate 1 , a material roller 2 , a first driving assembly, a second driving assembly, and a fixing assembly 5 .

[0056] There are two support plates 1, and the two support plates 1 are rotatably mounted on the frame.

[0057] There are multiple material rollers 2, which are evenly arranged around the rotation center line of the support plate 1 and are rotatably connected to the support plate 1. The first driving assembly is used to drive the support plate 1 to rotate around a preset angle, wherein the preset angle , n is equal to the number of material rollers 2. Specifically, the first driving assembly includes a first motor, which is a servo motor or a stepper motor. Preferably, the first motor is a stepper motor, which is fixedly arranged on the frame and is transmission-connected to one of the two support plates 1. Specifically, a first driving gear is fixedly arranged on the power output shaft of the first motor, and a first driven gear is fixedly connected to the power input end of one of the two support plates 1, and the first driving gear is meshed with the first driven gear.

[0058] The second drive assembly is used to drive the material roller 2 to rotate. Specifically, the second drive assembly includes a second motor, a second driving gear and a second driven gear. The second motor is fixedly mounted on the frame. The second driving gear is fixedly mounted on the power output shaft of the second motor. The second driven gear is fixedly mounted on the power input end of the material roller 2, and the second driving gear is meshed with the second driven gear. It should be noted here that the second drive assembly only drives one material roller 2 to rotate at a time. After one of the material rollers 2 has rolled up enough coated filter material, the free end of the coated filter material is fixed to another material roller 2. After that, the first drive assembly drives the support plate 1 to rotate, so that the second driven gear on the material roller 2 is meshed with the second driving gear on the second motor.

[0059] The fixing assembly 3 is installed on the material roller 2 , and is used to fix the free end of the coated filter material on the material roller 2 .

[0060] When in use, the free end of the coated filter material is fixed on a material roller 2 by using the fixing component 3, and then the second driving component drives the material roller 2 to rotate. After the material roller 2 has rolled up enough coated filter material, the free end of the coated filter material is fixed on another material roller 2 by using the fixing component 3. At the same time, the staff cuts the part between the two material rollers 2, and then the first driving component drives the material roller 2 to a position where its second driven gear meshes with the second driving gear. Then, the second driving component drives the material roller 2 to rotate, thereby achieving the purpose of continuing to roll up.

[0061] This structure is convenient for fixing the coated filter material in the coated filter material production device. By arranging the fixing component 3 on the material roller 2, the purpose of quickly fixing the coated filter material on the material roller 2 is achieved, thereby achieving the purpose of improving production efficiency.

[0062] In one embodiment, the fixing assembly 3 includes a clamping strip 31 and a locking mechanism 32 .

[0063] The material roller 2 is provided with a slot 21 adapted to the clip strip 31 along its length direction, and the first end of the clip strip 31 is hinged to the first end of the slot 21. The locking mechanism 32 is installed at the second end of the slot 21, and is used to lock the second end of the clip strip 31.

[0064] When it is necessary to fix the coated filter material, first, the locking mechanism 32 releases the lock on the second end of the clip 31, and then the clip 31 is rotated, preferably, the clip 31 is rotated at an angle β ≥ 90°, and then the free end of the coated filter material is placed on the material roller 2, and then the clip 31 is restored to its original position. Under the action of the clip 31 and the slot 21, the coated filter material can be fixed, and finally the locking mechanism 32 is used to lock the second end of the clip 31 to complete the fixation of the coated filter material.

[0065] The fixing component 3 of this structure is simple in structure and is convenient for fixing the membrane filter material.

[0066] In one embodiment, the locking mechanism 32 includes a slider 321 , a locking rod 322 , a locking slot 323 and a locking structure 324 .

[0067] The second end of the card slot 21 is provided with an installation cavity 22 communicated with the card slot 21, and the slider 321 is installed in the installation cavity 22 and can make reciprocating linear motion between the first working position and the second working position in the installation cavity 22 along the opening direction of the installation cavity 22, and the second working position of the slider 321 is far away from the opening direction of the installation cavity 22.

[0068] The first end of the locking rod 322 is hinged to the slider 321, and the second end extends toward the clamping strip 31, and the second end of the locking rod 322 has a locking portion 3201. The locking groove 323 cooperates with the locking portion 3201 to achieve the purpose of locking, and is opened at the second end of the clamping strip 31.

[0069] The locking structure 324 is installed in the installation cavity 22, and is used to keep the slider 321 in the first working position or the second working position. Specifically, when the slider 321 is in the first working position, the locking structure 324 keeps it in the first working position, and when the slider 321 is in the second working position, the locking structure 324 keeps it in the second working position.

[0070] Among them, the second end of the locking rod 322 has a first sliding part 3202, and a sliding groove 23 for guiding the sliding of the first sliding part 3202 is opened on the side wall of the installation cavity 22, and when the slider 321 moves from the first working position to the second working position, the first sliding part moves along the sliding groove 23 toward the axial center line of the installation cavity 22. Specifically, when the slider 321 is moved from the first working position to the second working position, under the action of the slide groove 23 and the first sliding part 3202, the second end of the locking rod 322 moves toward the direction close to the card strip 31 and the locking part 3201 is inserted into the locking groove 323, thereby achieving the purpose of locking the second end of the card strip 31. In the process of moving the slider 321 from the second working position to the first working position, under the action of the slide groove 23 and the first sliding part 3202, the second end of the locking rod 322 moves toward the direction away from the card strip 31 and the locking part 3201 is pulled out of the locking groove 323, thereby achieving the purpose of unlocking the card strip 31.

[0071] In one embodiment, the locking structure 324 includes a locking pull rod 3241 , a first elastic member 3242 and a connecting rod 3243 .

[0072] The first end of the locking pull rod 3241 is hinged to the inner wall of the installation cavity 22, and the second end has a second sliding portion 3203. The first elastic member 3242 is installed in the installation cavity 22, and in a natural state, the first elastic member 3242 has a tendency to move the slider 321 toward the direction close to the card slot 21. Specifically, the first elastic member 3242 is a first spring.

[0073] The connecting rod 3243 is located on a side of the slider 321 facing the locking rod 3241 and is fixedly connected to the slider 321. Preferably, the connecting rod 3243 and the slider 321 are integrally formed. The connecting rod 3243 is provided with a guide groove 3244 for guiding the sliding of the second sliding part 3203.

[0074] Specifically, the guide groove 3244 includes a slide-in and slide-out guide portion 3204, a first guide portion 3205, a temporary portion 3206 and a second guide portion 3207, and the slide-in and slide-out guide portion 3204, the first guide portion 3205, the temporary portion 3206 and the second guide portion 3207 are sequentially connected end to end to form a heart shape.

[0075] The second sliding portion 3203 slides along the sliding in and out guide portion 3204 and the first guide portion 3205 to the temporary portion 3206 and can temporarily stay in the temporary portion 3206. This process is the process in which the slider 321 moves from the first working position to the second working position, and when the second sliding portion 3203 temporarily stays in the temporary portion 3206, the locking structure 324 can keep the slider 321 in the second working position.

[0076] After the second sliding portion 3203 leaves the temporary portion 3206, it slides along the second guide portion 3207 and the sliding-in and sliding-out guide portion 3204. This process is the process of the slider 321 moving from the second working position to the first working position, and when the second sliding portion 3203 slides to the end of the sliding-in and sliding-out guide portion 3204 away from the temporary portion 3206, the locking structure can keep the slider 321 in the first working position.

[0077] When it is necessary to fix the second end of the card strip 31, the slider 321 is moved from the first working position to the second working position and the first elastic member 3242 is compressed. During this process, the second sliding portion 3203 slides along the sliding in and out guide portion 3204 and the first guide portion 3205 to the temporary portion 3206 and is temporarily positioned in the temporary portion 3206, thereby achieving the purpose of keeping the slider 321 in the second working position. At the same time, under the action of the slide groove 23 and the first sliding portion 3202, the second end of the locking rod 322 moves toward the direction close to the card strip 31 and allows the locking portion 3201 to be inserted into the locking groove 323, thereby achieving the purpose of locking the second end of the card strip 31.

[0078] When it is necessary to release the lock of the card strip 31, the slider is pushed so that the second sliding portion 3203 leaves the temporary portion 3206 and then slides along the second guide portion 3207 and the sliding in and out guide portion 3204. Then, under the action of the elastic member, the slider 321 is pushed from the second working position to the first working position. When the second sliding portion 3203 slides to the end of the sliding in and out guide portion 3204 away from the temporary portion 3206, the slider 321 moves to the first working position. During this process, under the action of the slide groove 23 and the first sliding portion 3202, the second end of the locking pull rod 322 moves in the direction away from the card strip 31 and makes the locking portion 3201 pulled out of the locking groove 323, thereby achieving the purpose of releasing the lock of the card strip 31. After that, the card strip 31 can be rotated to facilitate the placement of the coated filter material between the card strip 31 and the card groove 21, thereby achieving the purpose of facilitating the fixing of the coated filter material.

[0079] The locking structure 324 of this structure can lock the second end of the card strip 31 by pressing the slider 321 once, and can release the lock of the card strip 31 by pressing the slider 321 again, so that the second sliding part 3203 leaves the temporary part 3206 and slides along the second guide part 3207 and the sliding-in and sliding-out guide part 3204 and finally slides to the end of the sliding-in and sliding-out guide part 3204 away from the temporary part 3206. The structure is simple and convenient for fixing the coated filter material.

[0080] In one embodiment, the locking structure 324 further includes a third driving assembly 3245, and the third driving assembly 3245 is used to drive the slider 321 to slide. The third driving assembly 3245 is provided to facilitate the movement of the slider 321, thereby facilitating the locking and unlocking of the clamping strip 31.

[0081] In one embodiment, the third driving assembly 3245 includes a driving rod 3208 and a second elastic member 3209 .

[0082] The driving rod 3208 is mounted on the second end of the clamping strip 31 and is slidably connected to the clamping strip 31. The second elastic member 3209 is sleeved on the driving rod 3208, and in a natural state, it has a tendency to move the driving rod 3208 away from the clamping slot 21. Specifically, the second elastic member 3209 is a second spring.

[0083] When the locking strip 31 needs to be locked, the driving rod 3208 is pressed once and the slider 321 is driven from the first working position to the second working position by the driving rod 3208, thereby completing the locking of the locking strip 31. At the same time, under the action of the second elastic member 3209, the driving rod 3208 returns to its original position.

[0084] When the locking of the locking bar 31 needs to be released, the driving rod 3208 is pressed again to drive the slider 321 from the second working position to the first working position, thereby releasing the locking of the locking bar 31 .

[0085] The third driving assembly 3245 of this structure is simple in structure and is convenient for driving the movement of the slider 321. This improves the efficiency of locking and unlocking the card strip 31, thereby improving the production efficiency.

[0086] In one embodiment, the locking rod 322 includes an inner rod 3221 , an outer rod 3222 and a third elastic member 3223 .

[0087] The first end of the inner rod 3221 is hinged to the slider 321. The outer rod 3222 is sleeved on the inner rod 3221 and slidably connected to the inner rod 3221, and the first sliding portion 3202 and the locking portion 3201 are both arranged on the outer rod 3222. The third elastic member 3223 is installed in the outer rod 3222, and its two ends are respectively fixedly connected to the inner rod 3221 and the outer rod 3222, and in a natural state, the third elastic member 3223 has a tendency to make the inner rod 3221 move in a direction away from the slider 321.

[0088] Because the sliding distance of the second sliding part 3203 is farther than the actual distance between the first working position and the second working position during the movement of the slider 321, in order to facilitate the locking and unlocking of the slider 321, the clamping strip 31 needs to be rotated in the direction close to the axis line of the material roller 2 when it moves to be parallel to the axis line of the material roller 2. This creates a gap between the clamping strip 31 and the clamping slot 21, resulting in a poor locking effect.

[0089] By configuring the locking rod 322 to be retractable, there is no need to leave a gap between the card strip 31 and the card slot 21, and the card strip 31 can be locked and unlocked, thereby improving the locking effect.

[0090] In one embodiment, the slide groove 23 includes a first guide section 231 and a second guide section 232 that are interconnected, and the first guide section 231 is farther from the axis of the material roller, wherein the end of the first guide section 231 that is away from the axis of the material roller is farther from the axis of the mounting cavity 22, that is, the first guide section 231 is tilted, so that when the first sliding portion 3202 slides in the first guide section 231, the locking portion 3201 will move toward or away from the axis of the mounting cavity 22, so that the locking portion 3201 can be inserted into or pulled out of the locking groove 323, thereby achieving the purpose of locking and unlocking. The distance between the second guide section 232 and the axial center line of the installation cavity 22 remains unchanged, that is, the second guide section 232 is arranged parallel to the installation cavity 22, so that when the first sliding part 3202 slides in the second guide section 232, the locking part 3201 is always inserted into the locking groove 323, and when the slider 321 is in the second working position, the first sliding part 3202 is in the second guide section 232.

[0091] By configuring the slide groove 23 to be a first guide section 231 and a second guide section 232 , when the slider 321 is in the second working position, the first sliding portion 3201 is in the second guide section 232 , thereby achieving the purpose of enhancing the locking effect.

[0092] In the description of the present invention, a large number of specific details are described. However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
