Technical Field
[0001] This utility model relates to the technical field of dust removal industry, specifically to an automatic length recording and marking mechanism for a filter material folding machine. Background Technology
[0002] Automatic folding machines for dust collector filter media are industrial equipment specifically designed for processing dust collector filter media. They are mainly used to fold filter media into specific shapes (such as corrugated shapes) and are commonly used in the filter manufacturing industry. The device, through its continuously adjustable corrugation height design, can adapt to filter media of different materials (such as filter paper, non-woven fabric, non-woven felt, etc.), ensuring that the end face of the folded filter media is flat and the height is controllable. Most existing automatic folding machines for dust collector filter media have a simple design and no obvious segmentation marks after folding, which has the following shortcomings: 1. Manual marking is inefficient and inconsistent, and cannot meet the needs of mass production; 2. Existing automatic marking equipment (such as laser marking machines) is costly, complex to maintain, and cannot be operated flexibly in small spaces. Therefore, we propose an automatic length recording and marking mechanism for filter media folding machines. Utility Model Content

It facilitates the folding and cutting operations of automatic folding machines for dust removal filter materials and can effectively solve the problems in the background technology.
[0004] To achieve the above objectives, this utility model provides the following technical solution: An automatic length-counting and dotting mechanism for a filter material folding machine includes: A pen holder mechanism, used for marking lines on the surface of filter paper; A lead screw lifting mechanism is provided on the upper side of the folding machine and is used to adjust the initial height of the pen holder mechanism; A connecting seat is installed on the top of the paper folding machine. A double-axis cylinder is provided on the right side of the connecting seat. The piston rod of the double-axis cylinder is equipped with a double-axis cylinder piston. The pen holder mechanism includes a pen holder and a marker pen. The pen holder is located below the piston of the dual-axis cylinder. The marker pen slides in contact with a circular hole in the bottom wall of the pen holder. After the automatic length recording and marking mechanism of this filter paper folding machine is started, the marker pen draws marking lines on the filter paper for folding positioning.
[0005] This application utilizes a simple structure to perform marking operations on filter media, achieving a versatile, low-cost, automatic dot-marking mechanism for paper folding, which facilitates the paper folding and cutting operations of automatic paper folding machines for dust collector filter media.
[0006] Furthermore, the pen holder mechanism also includes a spring that acts as a buffer for the marker pen. The spring is located on the upper side of the marker pen and buffers the vertical rebound when the marker pen tip comes into contact with the filter material surface.
[0007] Furthermore, the pen holder mechanism also includes an adjusting screw for adjusting the buffer strength. The adjusting screw is threadedly connected to the top wall of the pen holder, and the lower end of the adjusting screw is fixedly connected to the upper end of the spring, thereby controlling the buffer strength of the spring in the automatic length recording and dotting mechanism of the filter material folding machine.
[0008] Furthermore, the pen holder mechanism also includes a boss for connecting the marker pen to prevent it from falling. The boss is movably sleeved on the outside of the marker pen. The boss is installed in conjunction with the round hole. The boss and the marker pen are integrally formed to prevent the marker pen from falling vertically downward along the round hole in the automatic length recording and marking mechanism of the filter paper folding machine.
[0009] Furthermore, the lead screw lifting mechanism includes a connecting seat three, a lead screw, a threaded seat, and a rocker arm. The connecting seat three is located on the upper side of the paper folding machine.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-5This embodiment provides a technical solution: an automatic length-recording and dotting mechanism for a filter material folding machine, including a pen holder mechanism 8 and a screw lifting mechanism 9. A connecting seat 4 is installed on the top of the folding machine 1. A dual-axis cylinder 5 is provided on the right side of the connecting seat 4. The piston rod of the dual-axis cylinder 5 is equipped with a dual-axis cylinder piston 6. A solenoid valve 10 is provided on the left side of the folding machine 1. The input end of the solenoid valve 10 is electrically connected to the output end of the controller. The air port 1 of the solenoid valve 10 is connected to the air port 2 of the dual-axis cylinder 5 through an air pipe 7. When using the automatic length-recording and dotting mechanism of the filter material folding machine, the air inlet of the solenoid valve 10 is connected to the air outlet of an external air compressor. The controller starts the folding machine 1, and the folding machine 1 transmits the running command to the controller in the form of an electrical signal. The controller controls the solenoid valve 10, which supplies compressed gas from the external air compressor to the dual-shaft cylinder 5. This causes the piston rod of the dual-shaft cylinder 5 to extend the piston 6. The piston 6 then moves the marker pen 83, which is fixed in the round hole, vertically downward through the pen holder 81 (the outer side of the marker pen 83 is movably fitted with a boss 84, which prevents the marker pen 83 from falling vertically downward along the round hole). The tip of the marker pen 83 moves downward and contacts the surface of the filter paper 2, marking it. At the same time, the filter paper 2 moves forward through the folding machine 1, forming a marking line 11 on the surface of the filter paper 2. After folding, a marking point is formed at the highest bend of the filter paper 2, which facilitates subsequent cutting.
[0017] Please see Figure 3The pen holder mechanism 8 includes a pen holder 81 and a marker pen 83. The pen holder 81 is located below the piston 6 of the dual-axis cylinder. The marker pen 83 slides in contact with a circular hole in the bottom wall of the pen holder 81. After the automatic length marking and dotting mechanism of this filter paper folding machine is activated, the marker pen 83 draws marking lines 11 on the filter paper 2 for folding positioning. The pen holder mechanism 8 also includes a spring 85 that cushions the marker pen 83. The spring 85 is located above the marker pen 83. The pen holder mechanism 8 also includes an adjusting screw 82 for adjusting the cushioning strength. The adjusting screw 82 is threadedly connected to the top wall of the pen holder 81. The lower end of 2 is fixedly connected to the upper end of the spring 85. The pen holder mechanism 8 also includes a boss 84 for connecting the marker pen 83 to prevent it from falling. The boss 84 is movably sleeved on the outside of the marker pen 83. The boss 84 is installed in conjunction with the round hole. During the contact between the tip of the marker pen 83 and the surface of the filter paper 2, the spring 85 buffers the rebound generated when the marker pen 83 contacts the surface of the filter paper 2, thereby improving the marking contact effect between the marker pen 83 and the surface of the filter paper 2. (Before using the device, rotate the adjusting screw 82 to make it move vertically through the threaded connection with the top wall of the pen holder 81. During this process, the adjusting screw 82...) The lower end of the filter paper 2 is driven by a spring 85 to rotate the marker 83 adaptively. To avoid excessive torsional force on the spring 85 during the rotation of the adjusting screw 82, the operator manually rotates the marker 83 in the same direction while the adjusting screw 82 is being rotated. By adjusting the position of the lower end of the adjusting screw 82, the initial pressure applied by the adjusting screw 82 to the spring 85 is adjusted, thereby adjusting the subsequent buffering strength of the spring 85. This is adjusted by the solenoid valve 10, which controls the extension time of the telescopic end of the dual-axis cylinder 5, thereby adjusting the contact time between the marker 83 and the filter paper 2 surface. After the marking line 11 on the surface of filter paper 2 is completed, the piston 6 of the dual-axis cylinder 5 is indirectly driven by the solenoid valve 10 to move the marker pen 83 upward and separate it from the filter paper 2. A sleeve can be slidably fitted between the adjusting screw 82 and the marker pen 83 to wrap the spring 85, thereby preventing the spring 85 from shifting vertically or horizontally during use. The spring 85 can be replaced after a period of use to prevent aging. This device uses the spring 85 to buffer the rebound generated when the marker pen 83 contacts the surface of the filter paper 2, and the buffering strength is adjustable. Other elastic elements can also be used.
[0018] Please see Figure 4The screw lifting mechanism 9 is located on the upper side of the folding machine 1. The screw lifting mechanism 9 includes a connecting seat 3 91, a screw 92, a threaded seat 93, and a rocker arm 94. The connecting seat 3 91 is located on the upper side of the folding machine 1. The screw 92 is rotatably connected between the upper and lower walls of the connecting seat 3 91 via a bearing. The threaded seat 93 is threadedly connected to the outer side of the screw 92. The front end of the threaded seat 93 is fixedly connected to the connecting seat 4. The rocker arm 94 is located at the upper end of the screw 92. The device also includes a scale rod 3 for height marking. The scale rod 3 is mounted on the upper side of the folding machine 1 via a fixing bracket. The outer side of the scale rod 3 is slidably connected to a sliding hole in the middle of the connecting seat 4. The device is initially used... The rocker arm 94 is rotated to drive the lead screw 92 to rotate. During the rotation of the lead screw 92, the threaded connection causes the threaded seat 93 to drive the connecting seat 4 to move vertically. The connecting seat 4 slides vertically along the outside of the scale rod 3 through its own sliding hole, while indirectly driving the marker pen 83 to move vertically in sync. This allows for the adjustment of the vertical distance between the marker pen 83 and the filter paper 2. During the vertical movement of the connecting seat 4, its upper horizontal plane moves vertically along the scale line on the scale rod 3, making it easier for staff to observe the position of the marker pen 83 and adjust its quantitative height. This device uses lead screw transmission to precisely adjust the initial height of the marker pen 83.
[0019] The working principle of the automatic length recording and marking mechanism for a filter paper folding machine provided by this utility model is as follows: In the initial stage of use, rotating the rocker arm 94 causes the lead screw 92 to rotate. During the rotation of the lead screw 92, the threaded connection causes the threaded seat 93 to move the connecting seat 4 vertically. The connecting seat 4 slides vertically along the outer side of the scale rod 3 through its own sliding hole, indirectly causing the marker pen 83 to move vertically synchronously, thereby adjusting the vertical distance between the marker pen 83 and the filter paper 2. During the vertical movement of the connecting seat 4, its upper horizontal plane moves vertically along the scale lines on the scale rod 3, making it convenient for workers to observe the position of the marker pen 83 and adjust its quantitative height. This automatic length recording and marking mechanism for the filter paper folding machine is used in this application. When the air inlet of the solenoid valve 10 is connected to the air outlet of the external air compressor, the folding machine 1 transmits the operating command to the controller via an electrical signal. The controller controls the solenoid valve 10, so that the compressed air from the external air compressor is supplied to the interior of the dual-shaft cylinder 5 through the solenoid valve 10. This causes the piston rod of the dual-shaft cylinder 5 to drive the piston 6 of the dual-shaft cylinder to extend. The piston 6 of the dual-shaft cylinder drives the marker 83 fixed in the round hole to move vertically downward through the pen holder 81 (the outer side of the marker 83 is movably fitted with a boss 84, which limits the contact of the marker 83 to prevent it from falling vertically downward along the round hole). The tip of the marker 83 moves downward to contact and mark the surface of the filter paper 2. At the same time, the filter paper 2 moves forward through the folding machine 1, so that the surface of the filter paper 2... A marking line 11 is formed. After folding, a marking point is formed at the highest bend of the filter paper 2, which facilitates subsequent cutting. During the contact between the tip of the marker 83 and the surface of the filter paper 2, the spring 85 buffers the rebound generated when the marker 83 contacts the surface of the filter paper 2, thereby improving the marking contact effect between the marker 83 and the surface of the filter paper 2. (Before using the device, rotate the adjusting screw 82 to make it move vertically through the threaded connection with the top wall of the pen holder 81. During this process, the lower end of the adjusting screw 82 drives the marker 83 to rotate adaptively through the spring 85. To avoid excessive torsional force on the spring 85 during the rotation of the adjusting screw 82, the operator manually rotates the marker in the same direction during the rotation of the adjusting screw 82.) 83. By adjusting the lower position of the adjusting screw 82, the initial pressure applied by the adjusting screw 82 to the spring 85 is adjusted, thereby adjusting the subsequent buffer strength of the spring 85. By adjusting the solenoid valve 10, the extension time of the telescopic end of the dual-axis cylinder 5 is controlled, thereby adjusting the contact time of the marker pen 83 with the surface of the filter paper 2. After the marking line 11 on the surface of the filter paper 2 is completed, the solenoid valve 10 adjusts the piston 6 of the dual-axis cylinder 5 to indirectly drive the marker pen 83 to move upward and contact and separate from the filter paper 2. A sleeve can be slidably fitted between the adjusting screw 82 and the marker pen 83 to wrap the spring 85, thereby preventing the spring 85 from shifting vertically or horizontally during use.
[0020] It is worth noting that the folding machine 1 disclosed in the above embodiments can be 55-1050-Ⅱ, the solenoid valve 10 can be ZQDF-3Y-40, and the controller controls the operation of the folding machine 1 and the solenoid valve 10 using methods commonly used in the prior art.
[0021] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
