Description

Technical Field

[0001] This application relates to the field of filter cloth edge cutting technology, and in particular to an edge cutting device for filter cloth production. Background Technology

[0002] Filter cloths are widely used in industrial production, such as in chemical, environmental protection, and pharmaceutical fields, and are commonly used in filtration and separation processes. During the production of filter cloths, after processes such as weaving and shaping, the edges of the filter cloths often have irregularities, burrs, and excess fabric, which not only affect the appearance quality of the filter cloths but may also lead to poor filtration performance and easy damage to the filter cloths during use.

[0003] In various industrial filtration equipment (such as bag filters, liquid filters, etc.), the filter element is the core filtration component. The filter layer of many filter elements requires the filter cloth to be cut into a circle to fit the cylindrical structure of the filter element.

[0004] A search revealed Chinese Patent Publication No. CN220413866U, which discloses an automatic filter cloth cutting device, comprising a fixed support assembly, a filter cloth positioning assembly, a filter cloth cutting assembly, a height adjustment assembly, and a filter cloth winding assembly. The fixed support assembly is located at the bottom of the entire cutting device. The filter cloth positioning assembly is mounted on the fixed support assembly. The filter cloth cutting assembly is mounted on one end of the fixed support assembly, with its input end facing the output end of the filter cloth positioning assembly. The height adjustment assembly is mounted on the fixed support assembly. The filter cloth winding assembly is located below the filter cloth cutting assembly and is connected to the fixed support assembly. This invention includes a filter cloth positioning assembly, comprising a positioning plate. The lower end face of the positioning plate and the upper end face of the worktable form a feeding channel. When the filter cloth passes through the feeding channel, the worktable and the positioning plate work together to position the filter cloth, keeping its surface flat and preventing protrusions, thus ensuring efficient cutting.

[0005] Regarding the aforementioned technologies, the inventors have discovered the following defects in this patent: In this patent, the scraps from the filter cloth cutting process accumulate at the cutting site, which affects the cutting progress. In addition, manual stopping of the machine is required to collect the scraps.

[0006] Therefore, in response to the above problems, the applicant provides a corner cutting device for filter cloth production. Utility Model Content

[0007] In order to solve the problems mentioned in the background art, this application provides a corner cutting device for filter cloth production.

[0008] This application provides a corner cutting device for filter cloth production, which adopts the following technical solution: A filter cloth production edge cutting device includes a frame and a disc. The disc is provided with a pressing mechanism to prevent filter cloth displacement. The pressing mechanism includes a sleeve, a rod, a spring and a limiting plate. The rod is sleeved on the sleeve, and the limiting plate is fixedly connected to the end of the rod. The spring is placed between the bottom surface of the sleeve and the top of the limiting plate.

[0009] The frame is equipped with a collection mechanism for collecting filter cloth debris. The collection mechanism includes two flip doors, which are respectively hinged to the inner walls of the two sides of the frame. The bottom surface of the flip doors is equipped with pulleys, and a pull strap is bolted to the pulleys. One end of the pull strap is fixedly connected to a slider. The slider is fixedly connected to a connecting plate, and the top surface of the connecting plate is attached to the bottom surface of the output end of the electric push rod.

[0010] Optionally, a bracket is vertically fixed to one side of the frame, and a base with a multi-stage electric actuator input end is vertically fixed to the bracket, and a disc is fixedly connected to the output end of the multi-stage electric actuator.

[0011] Optionally, a motor is bolted to the bottom surface of the disc, a connecting rod is fixedly connected to the rotating end of the motor, and a cutting blade is vertically fixedly connected to the end of the connecting rod.

[0012] Optionally, the bottom surface of the disc is fixedly connected to multiple sleeves in a ring array. One-tenth of the length of each sleeve is a cavity structure. A sleeve rod is fitted into the cavity of each sleeve. A pressure ring is fixedly connected to the bottom surface of the limiting disc, and the bottom surface of the pressure ring contacts the filter cloth.

[0013] Optionally, the frame is fixedly connected to inverted "T" shaped columns on both sides, and a table is fixedly connected to the top surface of the inverted "T" shaped columns. The table has a cutting hole, and the cutting knife is inserted into the cutting hole.

[0014] Optionally, a pair of flip doors are symmetrically hinged on both sides of the frame, and the two flip doors are attached to the tabletop. The tabletop and the inverted "T"-shaped column are combined to form a round table.

[0015] Optionally, pulleys are installed on the inner walls of the corresponding two sides of the frame, and a pull belt is rolled on the pulleys. A groove is opened at the bottom of the inverted "T" shaped column, and a slider is slidably connected in the groove of the inverted "T" shaped column. The bottom surface of the slider and the bottom of the inverted "T" shaped column are fixedly connected to both ends of the second spring.

[0016] Optionally, a holding plate is fixedly connected to the top surface of the inverted "T" shaped column, and a base for the input end of an electric push rod is fixedly connected to the bottom surface of the holding plate.

[0017] Optionally, the frame is provided with bending springs on the two sides and the bottom surfaces of the two flip doors. One end of the bending spring is fixedly connected to the frame, and the other end of the bending spring contacts the bottom surface of the flip door.

[0018] In summary, this application includes the following beneficial technical effects: 1. This utility model uses an electric push rod to pull the belt and cause the flip door to flip, so that the scraps of the filter cloth after circular cutting will automatically fall into the holding plate, thereby avoiding the scraps from scattering on the cutting site and affecting the cutting progress, and also avoiding the time-consuming and labor-intensive problem of manually stopping the machine to collect the scraps.

[0019] 2. This utility model uses a multi-stage electric push rod to drive a pressure ring to press down on the filter cloth. As the cutting blade continues to press down, the spring contracts, and the sleeve retracts into the sleeve, simultaneously positioning the pressure ring tightly against the filter cloth. With the synergistic action of the spring, sleeve, and sleeve, the pressure ring can always maintain a tight fit with the filter cloth. The spring always maintains its limiting effect on the pressure ring, providing a stable clamping force as the cutting blade penetrates the filter cloth. This ensures that the filter cloth remains flat and fixed during the cutting process, effectively avoiding the problems of filter cloth shifting and wrinkling. At the same time, there is no need to set up an additional independent drive or control structure to drive the action of the clamping block, which greatly simplifies the overall structure of the equipment and reduces the complexity and manufacturing cost of the equipment.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0023] This application discloses an edge cutting device for filter cloth production.

[0024] like Figure 1-6 As shown, a filter cloth production edge cutting device includes a frame 100 and a disc 104. The disc 104 is provided with a pressing mechanism that prevents the filter cloth 7 from shifting. The pressing mechanism includes a sleeve 2, a rod 3, a spring 4, and a limiting disc 5. The sleeve 2 is sleeved with the rod 3. The limiting disc 5 is fixedly connected to the end of the rod 3. The spring 4 is placed between the bottom surface of the sleeve 2 and the top surface of the limiting disc 5.

[0025] The frame 100 is provided with a collection mechanism that collects filter cloth 7 debris. The collection mechanism includes two flip doors 9, which are respectively hinged to the inner walls of the two sides of the frame 100. The bottom surface of the flip doors 9 is equipped with pulleys 11, and pull straps 12 are bolted to the pulleys 11. One end of the pull straps 12 is fixedly connected to a slider 13. The slider 13 is fixedly connected to a connecting plate 14, and the top surface of the connecting plate 14 is attached to the bottom surface of the output end of the electric push rod 15.

[0026] Please see Figure 3 A bracket 102 is vertically fixed to one side of the frame 100. A base with the input end of a multi-stage electric push rod 103 is vertically fixed to the bracket 102. A disc 104 is fixedly connected to the output end of the multi-stage electric push rod 103. The output end of the bracket 102 outputs from the input end and drives the disc 104 to move downward.

[0027] Please see Figure 5A motor 106 is bolted to the bottom surface of the disc 104. A connecting rod 107 is fixedly connected to the rotating end of the motor 106. A cutting blade 108 is vertically fixed to the end of the connecting rod 107. The rotating end of the motor 106 drives the connecting rod 107 and the cutting blade 108 to rotate. The four corners of the top of the motor 106 are bolted to the disc 104. This is a conventional installation method, which will not be described in detail here.

[0028] Please see Figure 5 The bottom surface of the disc 104 is fixedly connected to multiple sleeves 2 in a ring array. One-tenth of the length of each sleeve 2 is a cavity structure. A sleeve rod 3 is sleeved in the cavity of each sleeve 2. A pressure ring 6 is fixedly connected to the bottom surface of the limiting disc 5. The bottom surface of the pressure ring 6 contacts the filter cloth 7. The multi-stage electric push rod 103 drives the disc 104, sleeves 2 and pressure ring 6 to descend synchronously. The pressure ring 6 contacts the filter cloth 7 first. At the same time, as the multi-stage electric push rod 103 continues to drive the cutting blade 108 to move down, the sleeve rod 3 is vertically retracted in the cavity of the sleeve 2 under the action of the spring 4.

[0029] Please see Figure 2 The frame 100 has inverted "T" shaped columns 81 fixedly connected to both sides. A table tray 80 is fixedly connected to the top surface of the inverted "T" shaped columns 81. A cutting hole 800 is provided on the table tray 80. The cutting blade 108 is inserted into the cutting hole 800. The cutting blade 108 is driven by the multi-stage electric push rod 103 to first contact the filter cloth 7 and then penetrate the filter cloth 7 into the cutting hole 800. Under the drive of the motor 106, the cutting blade 108 cuts the filter cloth 7 into a circle.

[0030] Please see Figure 3 The frame 100 has a pair of hinged flip doors 9 on both sides. The two flip doors 9 are attached to the table 80. The table 80 and the inverted "T" shaped column 81 are combined to form a circular table 8. The circular table 8 is an integral structure. When the pair of flip doors 9 are in a parallel state, they are attached to the outer circumference of the table 80.

[0031] Please see Figure 2 The frame 100 has pulleys 11 installed on the inner walls of both sides. A pull belt 12 is rolled on the pulleys 11. The bottom of the inverted "T" shaped column 81 has a groove. A slider 13 is slidably connected in the groove of the inverted "T" shaped column 81. The bottom surface of the slider 13 and the bottom surface of the inverted "T" shaped column 81 are fixedly connected to both ends of the second spring 16. The pull belt 12 is a pulley and a bracket. The bracket is fixed on one side of the flip door 9 and the frame 100. The pulley can rotate on the bracket. When the slider 13 moves downward, it can pull the pull belt 12, which enables the flip door 9 to flip.

[0032] Please see Figure 3The top surface of the inverted "T" shaped column 81 is fixedly connected to a holding plate 17, and the bottom surface of the holding plate 17 is fixedly connected to a base of the input end of the electric push rod 15. The output end of the electric push rod 15 can be pushed downward from the input end to move the electric push rod 15 and the slider 13 downward. The cut filter cloth 7 is a round scrap. When the operator needs to take the round scrap from the holding plate 17, due to the restriction of the inverted "T" shaped column 81, one side of the round scrap needs to be cut off before it can be taken out.

[0033] Please see Figure 2 The frame 100 is provided with bending springs 10 on the two sides and the bottom surface of the two flip doors 9. One end of the bending spring 10 is fixedly connected to the frame 100, and the other end of the bending spring 10 contacts the bottom surface of the flip door 9. The bending spring 10 is set to automatically reset the flip door 9 after it flips.

[0034] The implementation principle of the edge cutting device for filter cloth production in this application embodiment is as follows: The operation of the electrical components in this application is controlled by a controller.

[0035] The operator first lays the filter cloth 7 as shown in the attached diagram of the instruction manual. Figure 1 On the flip door 9 in the state shown, the switch of the multi-stage electric push rod 103 is activated. The multi-stage electric push rod 103 drives the disc 104, connecting rod 107, cutting blade 108 and sleeve 2 to move down synchronously. The pressure ring 6 first contacts the filter cloth 7 on the top surface of the table 80. As the multi-stage electric push rod 103 continues to drive the cutting blade 108 through the filter cloth 7 into the cutting hole 800, the pressure ring 6 remains stationary. The spring 4 drives the sleeve rod 3 to retract in the cavity of the sleeve 2, so that the pressure ring 6 is tightly attached to the filter cloth 7 to prevent it from sliding. After the disc 104 drives the cutting blade 108 into the cutting hole 800, the electric push rod 15 and the motor 106 are started simultaneously. The output end of the electric push rod 15 is pushed downward from the input end. The output end of the electric push rod 15 drives the connecting plate 14 and the slider 13 to press down vertically. The spring 16 contracts. As the slider 13 moves downward, it drives the pull belt 12 to pull. As the position of the pull belt 12 moves downward, the pull belt 12 can pull the flip door 9 to flip. At the same time, the bending spring 10 contracts. The state at this time is as shown in the attached figure of the instruction manual. Figure 3 As shown, the filter cloth 7 falls automatically due to the flipping of the flip door 9.

[0036] Motor 106 drives connecting rod 107 and cutting blade 108 to rotate. Cutting blade 108 performs circular cutting on filter cloth 7, and the cut scraps automatically fall into holding plate 17.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
