Description

Blockage detection structure, blockage detection module and mat forming machine Technical Field

[0001] The invention relates to a material blocking detection structure, a material blocking detection module and a cushion material forming machine. Background Art

[0002] In the field of express delivery, the transported items may include fragile items, such as ceramics, glass products, electronic products, etc. When packaging these items, cushioning and shock-resistant materials are generally placed in the packaging box to play a role in cushioning, shock resistance, and impact resistance, thereby reducing the risk of items being broken or damaged.

[0003] The mat material forming machine is a device that converts mat materials into cushioning mat materials. It processes the mat materials through a set of forming rollers to generate three-dimensional mat materials with uneven surfaces. The three-dimensional mat materials can be laid in the packaging box to meet the transportation needs of fragile items.

[0004] During the discharge process of the mat material, if the discharge port is blocked by foreign objects or the cutter is blocked, the discharge will be abnormal, the mat material cannot be conveyed out, and the formed mat material cannot be separated from the forming roller in time. The conveying thrust reacts back to the mat material near the forming roller, and due to the protrusions on the surface of the forming roller, the mat material will be carried by the forming roller and wound onto the forming roller, and the formed mat material that has been separated from the forming roller will also be carried around. Because the distance between the forming rollers is limited, the forming roller will get stuck as the winding proceeds, causing damage or burning of the drive part. In addition, it will be more troublesome to clean up the large amount of mat material accumulated inside the machine, and the machine needs to be disassembled to proceed.

[0005] Therefore, how to overcome the above technical deficiencies is a technical problem that needs to be solved urgently by those skilled in the art.

[0006] Summary of the Invention

[0007] The purpose of the present invention is to provide a material blockage detection structure, a material blockage detection module and a mat material forming machine to solve the above technical problems.

[0008] According to a first aspect of the present invention, a material blockage detection structure is provided, comprising a motion component and a detection component.

[0009] The moving components are spaced apart on one side of the forming roller of the mat forming machine.

[0010] When the discharge port of the mat forming machine is blocked, the accumulated mat materials will drive the motion component to move and cause the motion component to trigger the detection component.

[0011] The blockage detection structure of the present invention is installed at the discharge port of a mat material forming machine (such as a bubble press), near the forming roller. The forming roller of the mat material forming machine processes the mat material (such as kraft paper) into a three-dimensional mat material with an uneven surface through the protrusions on its surface. The mat material can enter the cutting station on the mat material forming machine after passing through the channel of the discharge port; when the discharge port is blocked, the mat material cannot be transported out, and the accumulated mat material will drive the moving component to move until the moving component triggers the detection component. The detection component is connected to the control device of the mat material forming machine. After the detection component is triggered, the control device of the mat material forming machine controls the driving device of the forming roller to stop running, thereby timely avoiding subsequent damage to the driving device, and the operator can pull out the blocked mat material in time when he finds that the work has stopped, without the need to disassemble the machine, and the operation is convenient and quick.

[0012] In some embodiments, the motion assembly can guide the accumulated mat material to move toward the forming roller, which winds the mat material. The wound mat material drives the motion assembly to move, causing the motion assembly to trigger the detection assembly. Thus, when the discharge port is blocked, the mat material cannot be conveyed out, and the thrust of the conveying is reacted to the mat material near the forming roller. At the same time, under the combined action of the protrusions on the forming roller and guided by the motion assembly, the mat material is wound by the forming roller. As the range of the forming roller winding the mat material increases, it gradually approaches the motion assembly until the mat material is located between the forming roller and the motion assembly. It then moves with the motion assembly, and then the detection assembly is triggered. The detection assembly is connected to the control device of the mat forming machine. After the detection assembly is triggered, the control device of the mat forming machine controls the drive device of the forming roller to stop running, thereby timely avoiding subsequent damage to the drive device. When the operator finds that the mat material has stopped working, he can pull out the wound mat material in time without disassembling the machine, which is convenient and quick to operate.

[0013] In some embodiments, the minimum distance between the motion assembly and the roller surface formed by the protrusions of the forming roller can be less than the sum of the protrusion height and the thickness of the mat material. Thus, when a paper jam occurs, the mat material is wound onto the forming roller. Due to the distance limit, once wound and positioned between the forming roller and the motion assembly, it can be triggered by rotating a certain angle. This prevents winding through a large angle, resulting in a quick response, reduced risk of driver damage, and improved efficiency in removing the mat material after a paper jam.

[0014] In some embodiments, the motion assembly may include a rotating member rotatably mounted on one side of the forming roller. The mat material winding drives the rotating member to rotate, thereby triggering the detection assembly. Thus, when the mat material is wound around the forming roller and contacts the motion assembly, the winding of the mat material drives the motion assembly to rotate. The rotation of the motion assembly triggers the detection assembly, causing the drive to stop.

[0015] In some embodiments, the rotating member may include a rod or plate, with one end of the rotating member contacting the mat material, and a portion on the same side as the mat material being used to trigger the detection assembly, a portion on the side opposite the mat material being used to trigger the detection assembly, or a portion at the rotation center of the rotating member being used to trigger the detection assembly. Thus, the end in contact with the mat material drives the rotating member to rotate, and after the rotating member rotates, the detection assembly is triggered, thereby stopping the drive. The detection assembly can be triggered at the same side of the rotating member that contacts the mat material, at the opposite side, or at the rotation center of the rotating member. All three parts can be triggered, meaning that the entire rotating member can serve as a triggering structure.

[0016] In some embodiments, the motion assembly may further include a limiting rod and a limiting slot, with the limiting rod or the limiting slot being provided on the rotating member, and the limiting rod moving within the limiting slot. Thus, when the rotating member rotates, it is restricted by the limiting slot, including the rotation angle and path. This serves to control the limited angle, prevent damage to the detection assembly due to excessive rotation, and ensure smooth triggering of the detection assembly, thereby improving detection stability.

[0017] In some embodiments, the rotating member may include at least two connected connecting segments, the two connecting segments forming an angle, the connecting segments being arranged along the mat material conveying direction, and the vertical distance between the connecting segments and the mat material conveying path gradually decreasing. Thus, the angle of the rotating member is set abruptly, with the connecting segment having a relatively large angle and being farther from the conveying path, so that when a material blockage occurs at the discharge port, the mat material is easily carried by the forming roller. If the angle is small, when the forming roller tends to wind the mat material, the probability of being pressed down by the reaction of the rotating member is high, making it difficult to trigger detection sensitively, resulting in the mat material being blocked in the conveying path. When the mat material is subsequently pulled out, the amount pulled out is large, the folding of the mat material is chaotic, and this increases the waste of this part of the low-quality mat material and reduces efficiency. The angle setting can increase the probability of the mat material near the forming roller being wound by the belt, thereby improving detection sensitivity and reducing mat material loss. In addition, it can also play a certain guiding role in guiding the mat material transmission.

[0018] In some embodiments, a guide portion may be provided at one end of the rotating member near the forming roller. The guide portion may be flat or curved on the side facing the forming roller, and the guide portion is used to guide the formed mat material so that it does not get stuck on the end of the rotating member when being pulled out and retracted. Thus, after detecting a paper jam, the drive stops, and the staff then pulls the mat material out. During the pulling-out process, since the mat material has already been formed and its surface is uneven, it may get stuck on the end of the rotating member, making it difficult to pull out or even tearing. By providing the guide portion, the raised portion of the mat material is guided so that it does not get stuck on the rotating member, thereby ensuring smooth pulling out of the mat material and reducing the possibility of tearing the mat material, thereby improving processing efficiency and mat material quality.

[0019] In some embodiments, the motion assembly may further include a first return member connected to the rotating member, the first return member being configured to return the rotating member to its original position after rotation. Thus, on the one hand, during the movement of the rotating member, the rotating member may not be able to return to its original position in time due to mat material debris or roughness of the parts, and the next paper guide cannot be inspected. Therefore, the provision of the first return member provides a force to the rotating member, greatly reducing the probability of the rotating member getting stuck, thereby ensuring normal rotation of the rotating member and ensuring the detection. On the other hand, if the rotating member is installed below the conveying path and the center of gravity of its detection portion is above the rotation center of gravity, it needs to be reset for a second detection. However, due to gravity, it cannot be automatically reset and manual operation is relatively cumbersome. Therefore, the provision of the first return member exerts a force on the rotating member to ensure the reset of the rotating member, allowing the detection to be carried out continuously. In addition, when the mat material is pulled out and retracted, the mat material may also drive the rotating member to rotate, but the degree of rotation may not be sufficient or excessive. The provision of the first return member ensures that the rotation is in place. In addition, the first return member can maintain a certain force on the rotating member to prevent it from being easily pushed to rotate without paper jamming.

[0020] In some embodiments, the rotating member may include a roller, a gear, a partial gear, or a cam, and the mat material drives the roller, gear, partial gear, or cam to rotate to trigger the detection assembly. Thus, when the mat material is wound around the belt and contacts the rotating member, driving the rotating member to rotate, the rotation of the rotating member triggers the detection assembly, causing the drive to stop, resulting in a simple and efficient structure.

[0021] In some embodiments, the motion component may further include a second reset component connected to the rotating member, and the second reset component is used to restore the rotating member to its original position after rotation. Thus, after one detection, the rotating member rotates. If a second detection is to be performed, some detection members need to return to their original positions in order to accurately perform the second detection. The second reset component is provided to restore the rotating member to its original position, thereby ensuring the accuracy of subsequent detection. In addition, if the detection component is an angle detector, it may not need to be reset, and when the mat is pulled out, the retracted mat itself will also reverse the rotating member, but it may not be reversed in place or reversed too much. The purpose of providing the second reset component is to ensure accurate reset. In addition, the second reset component can keep the rotating member at a certain force to prevent it from being easily pushed to rotate without paper blocking.

[0022] In some embodiments, the motion assembly may include a track positioned on one side of the forming roller and a moving member slidably mounted on the track. The moving member triggers the detection assembly at least one of the following times: at the beginning of sliding, during sliding, or at the end of sliding. Thus, the detection assembly can be triggered at the beginning, middle, or end of the movement of the moving member, or at any of two or three times simultaneously, causing the driver to stop motion and ensuring detection stability.

[0023] In some embodiments, the path within the track for the moving member to slide can be curved, with the concave portion of the arc oriented toward the forming roller, and the arc gradually approaching the forming roller as the forming roller rotates. This allows the distance between the moving member and the forming roller to decrease gradually, ensuring that the moving member triggers the detection assembly smoothly and reducing interference from other sudden changes in the detection results. Furthermore, as the forming roller winds the mat material, the mat material becomes increasingly adherent to the forming roller, matching the overall thickness of the mat material.

[0024] In some embodiments, the motion assembly may further include a third reset member connected to the moving member, the third reset member being used to return the moving member to its original position after movement. Thus, on the one hand, during the movement of the moving member, the moving member may not be able to reset in time due to pad material debris or part roughness, and the paper guide cannot be detected the next time. Therefore, by providing the third reset member, a force is provided for the moving member, which greatly reduces the probability of the moving member getting stuck, thereby ensuring the normal movement of the rotating member and ensuring the detection. On the other hand, if the moving member is installed below the conveying path and its gravity is downward, it needs to be reset if it is to be detected for the second time. However, due to gravity, it cannot be automatically reset and manual operation is more troublesome. Therefore, by providing the third reset member, a force is applied to the moving member to ensure the reset of the moving member so that the detection can be carried out continuously. In addition, the third reset member can keep the moving member at a certain force to avoid being easily pushed to move without blocking the paper.

[0025] In some embodiments, the motion component may include an upper paper guide and a lower paper guide, and the number of the detection component is at least one.

[0026] The upper paper guide and the lower paper guide are distributed up and down, and a channel for discharging the mat material is formed between the upper paper guide and the lower paper guide. At least one of at least a portion of the upper paper guide and at least a portion of the lower paper guide can be relatively away from or close to the other.

[0027] When at least one of at least a portion on the upper paper guide and at least a portion on the lower paper guide is relatively far away from the other, at least a portion on the upper paper guide and / or at least a portion on the lower paper guide can trigger the detection component.

[0028] Thus, the forming roller of the mat forming machine processes the paper (such as kraft paper) into a three-dimensional mat material with an uneven surface. The mat material can enter the cutting station on the mat forming machine after passing through the channel between the upper paper guide and the lower paper guide. The upper paper guide and the lower paper guide can guide the mat material into the cutting station on the mat forming machine. When paper jam occurs, that is, when the mat material is accumulated between the upper paper guide and the lower paper guide, the accumulated mat material will drive at least one of at least a part of the upper paper guide and at least a part of the lower paper guide to move relatively away from the other until at least a part of the upper paper guide triggers the detection component, at least a part of the lower paper guide triggers the detection component or at least a part of the upper paper guide triggers the detection component A part and at least a part on the lower paper guide respectively trigger the detection component, the detection component is connected to the control device of the mat material forming machine, after the detection component is triggered, the control device of the mat material forming machine controls the driving device of the forming roller to stop running, thereby avoiding subsequent damage to the driving device, and the operator can remove the blocked mat material in time when it finds that the work has stopped, thereby avoiding the subsequent accumulation of a large amount of mat material. The detection of the degree of mat material blockage can be set. As long as the mat material is blocked, the detection component will be triggered, thereby ensuring that a large amount of mat material will not accumulate between the upper paper guide and the lower paper guide. After stopping work, a small amount of accumulated mat material can be easily removed without disassembling the machine.

[0029] In some embodiments, the end of the upper paper guide can be hinged to the equipment body of the mat material forming machine, the upper paper guide is provided with an upper triggering portion, and the detection component is provided above the upper triggering portion.

[0030] When a cushion material is blocked between the upper paper guide and the lower paper guide, the blocked cushion material can drive the upper trigger portion away from the lower paper guide and the upper trigger portion can trigger the detection component.

[0031] Therefore, when the cushion material is blocked between the upper paper guide and the lower paper guide, since the end of the upper paper guide is hinged to the equipment body of the cushion material forming machine, the blocked cushion material can lift the upper trigger part on the upper paper guide, and the upper trigger part flips upward with the hinge position of the upper paper guide as the center, and the upper trigger part moves away from the lower paper guide until the upper trigger part triggers the detection component.

[0032] In some embodiments, the end of the upper paper guide can be provided with an upper limit hole, and the equipment body of the mat material forming machine is provided with an upper limit rod, which is inserted into the upper limit hole and can move in the upper limit hole. Therefore, the cooperation between the upper limit hole and the upper limit rod can limit the flipping angle of the upper trigger part. When the mat material is not blocked, the upper limit rod is located at one end of the upper limit hole. When the mat material is blocked, the upper trigger part flips upward with the hinge position of the upper paper guide as the center and moves relatively to the upper limit rod in the upper limit hole. When the upper limit rod moves to the other end of the upper limit hole, the upper trigger part just triggers the proximity switch or contact switch. Moreover, due to the existence of the upper limit rod, the upper trigger part cannot continue to flip upward at this time, which can prevent the upper trigger part from further squeezing the detection component and damaging the detection component.

[0033] In some embodiments, the end of the lower paper guide can be hinged to the equipment body of the mat material forming machine, the lower paper guide is provided with a lower trigger portion, and the number of detection components is two, one detection component is provided above the upper trigger portion, and the other detection component is provided below the lower trigger portion.

[0034] When a cushion material is blocked between the upper paper guide and the lower paper guide, the blocked cushion material can drive the upper trigger part and the lower trigger part to move away from each other, and the upper trigger part can trigger one detection component and the lower trigger part can trigger another detection component.

[0035] Therefore, when the cushion material is blocked between the upper paper guide and the lower paper guide, since the end of the upper paper guide is hinged to the equipment body of the cushion material forming machine and the end of the lower paper guide is also hinged to the equipment body of the cushion material forming machine, the blocked cushion material can push up the upper trigger part on the upper paper guide, and the upper trigger part flips upward with the hinge position of the upper paper guide as the center. At the same time, the blocked cushion material can push down the lower trigger part on the lower paper guide, and the lower trigger part flips downward with the hinge position of the lower paper guide as the center, and the upper trigger part and the lower trigger part move away from each other until the upper trigger part and the lower trigger part respectively trigger the detection component.

[0036] In some embodiments, the spacing between the upper and lower triggering parts can gradually decrease along the direction of mat material transport. Thus, this arrangement of the upper and lower triggering parts can not only guide the mat material into the passage between the upper and lower paper guides, but also enable the upper and lower triggering parts to flexibly sense mat material blockages, allowing the detection component to provide timely feedback.

[0037] In some embodiments, the end of the upper paper guide may be provided with an upper limit hole, and the equipment body of the mat material forming machine is provided with an upper limit rod, which is inserted into the upper limit hole and can move in the upper limit hole. The end of the lower paper guide may be provided with a lower limit hole, and the equipment body of the mat material forming machine is provided with a lower limit rod, which is inserted into the lower limit hole and can move in the lower limit hole. Therefore, the cooperation between the upper limit hole and the upper limit rod can limit the flipping angle of the upper trigger part, and the cooperation between the lower limit hole and the lower limit rod can limit the flipping angle of the lower trigger part. When there is no blockage of the cushion material, the upper limit rod is located at one end in the upper limit hole, and the lower limit rod is located at one end in the lower limit hole. When blockage of the cushion material occurs, the upper trigger part flips upward with the hinge position of the upper paper guide as the center and moves relatively to the upper limit rod in the upper limit hole, and the lower trigger part flips downward with the hinge position of the lower paper guide as the center and moves relatively to the lower limit rod in the lower limit hole. When the upper limit rod moves to the other end in the upper limit hole, the upper trigger part just triggers the detection component, and due to the existence of the upper limit rod, the upper trigger part cannot continue to flip upward at this time. When the lower limit rod moves to the other end in the lower limit hole, the lower trigger part just triggers the detection component, and due to the existence of the lower limit rod, the lower trigger part cannot continue to flip downward at this time. This can prevent the upper trigger part and the lower trigger part from further squeezing the detection component and damaging the detection component.

[0038] In some embodiments, an upper reset mechanism and a lower reset mechanism may also be included.

[0039] When the pad material blocking the upper paper guide and the lower paper guide is removed, the upper reset mechanism can drive the upper trigger part close to the lower trigger part to reset the upper trigger part, and the lower reset mechanism can drive the lower trigger part close to the upper trigger part to reset the lower trigger part.

[0040] Therefore, after removing the mat material blocked between the upper paper guide and the lower paper guide, the upper trigger part and the lower trigger part can be automatically reset under the action of the upper reset mechanism and the lower reset mechanism, preparing for the subsequent production of the mat material.

[0041] In some embodiments, the upper reset mechanism may include an upper mounting frame, an upper reset column, and an upper reset spring provided on the equipment body of the mat material forming machine.

[0042] The upper mounting frame is provided with an upper long hole.

[0043] One end of the upper reset column is arranged on the upper trigger part, and the other end is inserted into the upper long hole. The upper reset spring is sleeved on the upper reset column.

[0044] The lower reset mechanism may include a lower mounting frame, a lower reset column and a lower reset spring provided on the equipment body of the mat material forming machine.

[0045] The lower mounting frame is provided with a lower long hole.

[0046] One end of the lower reset column is arranged on the lower trigger part, and the other end is inserted into the lower long hole. The lower reset spring is sleeved on the lower reset column.

[0047] Therefore, when the cushion material is blocked between the upper paper guide and the lower paper guide, the blocked cushion material will push up the upper trigger part, and the upper trigger part will drive the upper reset column to move synchronously, and the upper reset spring on the upper reset column will be compressed. At the same time, the blocked cushion material will push the lower trigger part downward, and the lower trigger part will drive the lower reset column to move synchronously, and the lower reset spring on the lower reset column will be compressed. When the cushion material blocked between the upper paper guide and the lower paper guide is removed, the upper trigger part and the lower trigger part are automatically reset under the restoring force of the upper reset spring and the lower reset spring, that is, the upper paper guide as a whole and the lower paper guide as a whole are automatically reset, preparing for the subsequent production of cushion materials.

[0048] In some embodiments, at least one of the upper paper guide and the lower paper guide may be slidably mounted on the main body of the mat forming machine.

[0049] When cushion material is blocked between the upper paper guide and the lower paper guide, the blocked cushion material can drive at least a portion of the upper paper guide and / or at least a portion of the lower paper guide to trigger the detection component.

[0050] Therefore, when the cushion material is blocked between the upper paper guide and the lower paper guide, the blocked cushion material can push up the upper paper guide, push down the lower paper guide, or push up the upper paper guide and push down the lower paper guide at the same time, until at least a part of the upper paper guide triggers the detection component, at least a part of the lower paper guide triggers the detection component, or at least a part of the upper paper guide and at least a part of the lower paper guide trigger the detection component respectively.

[0051] According to a second aspect of the present invention, a material blockage detection module is provided, comprising a frame, on which the material blockage detection structure described in the first aspect is installed.

[0052] The material blockage detection module of the present invention can be installed as a whole on the equipment that needs to be detected, and plays a role in detecting material blockage in the equipment. When the equipment's mat material is being formed and output, a blockage occurs, and the material blockage detection module can interact with the mat material, thereby producing a triggering effect to achieve material blockage detection in the mat material transportation.

[0053] According to a third aspect of the present invention, a mat material forming machine is provided, comprising an equipment body, the equipment body being provided with a forming roller, a driving device and a control device, and the equipment body being further provided with either the material blockage detection structure described in the first aspect or the material blockage detection module described in the second aspect, the detection component being electrically connected to the control device, and the control device being electrically connected to the driving device.

[0054] The mat material forming machine of the present invention has a forming roller that processes the mat material (such as kraft paper) into a three-dimensional mat material with an uneven surface. When the discharge port is blocked, the mat material cannot be transported out, and the accumulated mat material will drive the motion component to move until the motion component triggers the detection component. After the detection component is triggered, the control device controls the driving device of the forming roller to stop running, thereby timely avoiding subsequent damage to the driving device, and when the operator finds that the work has stopped, the stuck mat material can be pulled out in time to avoid the subsequent accumulation of large amounts of mat material. After stopping work, a small amount of mat material can be easily taken out without disassembling the machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0068] In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer" and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features referred to.

[0069] First, the present invention discloses a material blockage detection structure.

[0070] A material blockage detection structure includes a motion component and a detection component. The motion component is spaced apart on one side of a forming roller of a mat forming machine. "Space" means that a certain distance is maintained between the motion component and the forming roller of the mat forming machine. When the discharge port of the mat forming machine is blocked, the accumulated mat material will drive the motion component to move and cause the motion component to trigger the detection component.

[0071] The blockage detection structure of the present invention is installed at the discharge port of a mat material forming machine (such as a bubble press), near the forming roller. The forming roller of the mat material forming machine processes the mat material (such as kraft paper) into a three-dimensional mat material with an uneven surface through the protrusions on its surface. The mat material can enter the cutting station on the mat material forming machine after passing through the channel of the discharge port; when the discharge port is blocked, the mat material cannot be transported out, and the accumulated mat material will drive the moving component to move until the moving component triggers the detection component. The detection component is connected to the control device of the mat material forming machine. After the detection component is triggered, the control device of the mat material forming machine controls the driving device of the forming roller to stop running, thereby timely avoiding subsequent damage to the driving device, and the operator can pull out the blocked mat material in time when he finds that the work has stopped, without the need to disassemble the machine, and the operation is convenient and quick.

[0072] FIG1 schematically shows the structure of a material blockage detection structure according to an embodiment of the present invention.

[0073] Referring to Figures 1 and 11, a material blockage detection structure includes a motion component and a detection component 3. The motion component moves to trigger the detection component 3. When the discharge port of the equipment body 7 (shown in Figure 11) is blocked, the conveying force transmitted by the forming roller 5 to the mat material 4 reacts back to the mat material 4 and the forming roller 5. At the same time, under the thrust of the protrusion 51 on the forming roller 5 and guided by the motion component, the forming roller 5 winds up the mat material 4 until it is brought between the forming roller 5 and the motion component. Then, the mat material 4 drives the motion component to move, triggering the detection component 3, causing the drive to stop and the forming roller 5 to stop rotating.

[0074] To ensure that the moving assembly can be driven by the mat material 4 , the minimum distance between the moving assembly and the roller surface formed by the protrusions 51 of the forming roller 5 is smaller than the sum of the height of the protrusions 51 and the thickness of the mat material 4 .

[0075] This embodiment discloses a motion mode of the motion component, which is rotation.

[0076] The rotation is explained below.

[0077] 1 , the motion assembly includes a rotating member 11 . In this embodiment, the rotating member 11 can be basically a rod or a plate.

[0078] It can be one rod, two rods or multiple rods, the rods can be independent or connected, and the rotation point can be at the end or at any position between the two ends.

[0079] For a plate, it can be two plates or multiple plates, multiple plates can be connected or independent, and the rotation connection of the plate can be at the end or at any position between the two ends.

[0080] For plate or rod, the structural principle is the same, and the rotating member 11 in the present embodiment is described with a plate. Of course, the plate has a smoother surface relative to the rod, which is more conducive to the movement of the mat material 4 relative to the rod.

[0081] When the non-rotating portion of the rotating member 11 is used as the detection portion, in some embodiments, the detection assembly 3 includes a micro switch, a distance sensor, a displacement sensor, a photoelectric sensor, etc. When the mat material 4 is wound and moves along the circumferential direction of the forming roller 5, the mat material 4 can drive one end of the rotating member 11 to rotate.

[0082] FIG1 shows a micro switch. For the micro switch, the triggering portion of the micro switch contacts the rotating member 11, or the rotating member 11 rotates and then contacts the rotating member 11. After the contact, the rotating member 11 continues to rotate to trigger the micro switch.

[0083] As for the distance sensor, the distance sensor does not contact the rotating part 11 and is used to detect the change in the distance from the non-rotating connection point of the rotating part 11. A distance value can be set. As the rotating part 11 rotates, when the distance value reaches the set value, the distance sensor is triggered.

[0084] The displacement sensor may be a magnetic, optical, or wire-drawn displacement sensor, which is also triggered as the rotating member 11 rotates and at a certain set value or position.

[0085] The above lists only a few implementation methods, and other alternative methods are within the scope of protection of this application.

[0086] When the rotation point of the rotating member 11 is used as the detection portion, in some embodiments, the detection assembly 3 includes angle and torque sensors. The torque sensor can also be used for detection at non-rotation points, and each is set to a set value. When the rotating member 11 rotates, the angle and torque at the rotation point change, and when they reach the set value, the trigger is triggered.

[0087] In some embodiments, after the rotating member 11 rotates, it may not be able to return to its original position due to scraps of the mat 4 or the roughness of the material, or part of the rotating member 11 itself may even be damped rotation and cannot automatically reset, or the plate cannot be reset due to gravity. Manual operation is required, which is relatively troublesome. Therefore, in some embodiments, referring to Figure 1, the motion assembly also includes a first reset member 14. In this embodiment, the first reset member 14 includes a spring, a coil spring, a torsion spring, or a tension spring. One end of the first reset member 14 is connected to the rotating member 11. After being pulled by the mat 4 to rotate, and after the staff pulls out the mat 4, the first reset member 14 drives the rotating member 11 to rotate and reset for the next inspection, reducing manual operation and being more convenient. In addition, the first reset member 14 can keep the rotating member 11 under a certain force, avoiding false triggering due to vibration or other factors, and improving stability.

[0088] In some embodiments, to facilitate smooth retraction of the mat material 4 and reduce the possibility of the mat material 4 becoming stuck or torn by the end of the rotating member 11, a guide portion 13 is provided at the end of the rotating member 11 near the forming roller 5, as shown in FIG1 . The guide portion 13 is curved or flat on the side facing the forming roller 5, and the rotating member 11 and the guide portion 13 form an angle with each other. When the mat material 4 is retracted, the guide portion 13 guides the mat material 4 or its protrusions, preventing jams and significantly reducing the possibility of tearing, ensuring smooth and quick removal of the mat material 4.

[0089] In some embodiments, referring to Figure 1, the rotating member 11 includes at least two connected connecting segments 12. If there are three, they are connected end to end, and the connecting segments 12 can be straight or curved, and form a sudden angle at the connected position, so that the paper jam can be more easily wound by the forming roller 5 at a position close to the forming roller 5, thereby improving the triggering effect of the detection component 3.

[0090] In some embodiments, referring to FIG. 1 , the guide portion 13 is provided on the connecting section 12 close to the forming roller 5 .

[0091] In some embodiments, a limiting structure is provided to account for the rotational range of the plate or rod, which may damage the detection assembly 3 due to excessive rotation. Therefore, referring to FIG1 , the motion assembly further includes a limiting rod 16 and a limiting slot 17 . The limiting rod 16 and limiting slot 17 are disposed on the sidewall of the plate or rod. The limiting rod 16 moves within the limiting slot 17 to limit the rotation of the rotating member 11 . The set values ​​of the above sensors are all within the rotational range of the rotating member 11 .

[0092] In some embodiments, because there are at least two forming rollers 5, the mat material 4 may be wrapped around any one of the two forming rollers 5. Therefore, the structure in the above embodiment can be set one-to-one to match the number of forming rollers 5 to ensure that all are detected in place.

[0093] FIG2 schematically shows the structure of a material blockage detection structure according to another embodiment of the present invention.

[0094] 2 , compared with the material blockage detection structure shown in FIG1 , the most basic rotating member 11 in this embodiment can be a wheel.

[0095] For one wheel, it can be two wheels, or multiple wheels. As for the wheel, it can be a roller, a gear, an incomplete gear, or a cam, etc. The specific number can be set according to actual needs and is not limited in this embodiment.

[0096] The following is an explanation of the wheel.

[0097] Referring to Figure 2, for the wheel, in some embodiments, the detection assembly 3 includes a sensor for detecting angle or torque, and the triggering angle and torque values ​​can be set as needed. When the mat material 4 is wound between the rotating member 11 and the forming roller 5, the mat material 4 can drive the rotating member 11 to rotate. After the rotating member 11 rotates, the angle changes and the torque value changes. When the set value is reached, the sensor is triggered. The sensor sends an electrical signal to the control device or the drive device that drives the forming roller 5 to rotate, causing the forming roller 5 to stop rotating, and subsequent staff can pull out the mat material 4.

[0098] After being pulled out, the rotating member 11 may not necessarily return to its original position, resulting in inaccurate data. Therefore, the motion assembly also includes a second reset member 15. This embodiment exemplifies that the second reset member 15 includes a torsion spring, coil spring, or tension spring, among other options. Theoretically, any member capable of driving the rotating member 11 to its original position will suffice. If the rotating member 11 rotates relative to its axis, the third reset member 23 is connected to the side wall of the rotating member 11. If the rotating member 11 rotates synchronously with its axis, the second reset member 15 is connected to the side wall or axis of the rotating member 11. Furthermore, the second reset member 15 maintains a certain force on the rotating member 11, preventing false triggering due to vibration or other factors and improving stability.

[0099] In some embodiments, a limiting structure is provided to account for the wheel's rotational range, which may damage the detection assembly 3 due to excessive rotation. Therefore, the motion assembly may further include a limiting rod and a limiting slot, with the limiting rod or limiting slot being provided on the sidewall of the wheel (the wheel portion in FIG2 is not shown). The limiting rod moves in the limiting slot to limit the rotation of the rotating member 11. The set values ​​of the above sensors are all within the rotational range of the rotating member 11.

[0100] In some embodiments, because there are at least two forming rollers 5, the mat material 4 may be wrapped around any one of the two forming rollers 5. Therefore, the structure in the above embodiment can be set one-to-one to match the number of forming rollers 5 to ensure that all are detected in place.

[0101] FIG3 schematically shows the structure of a material blockage detection structure according to a third embodiment of the present invention.

[0102] This embodiment discloses a motion mode of the motion component, which is movement.

[0103] The following describes movement.

[0104] Referring to Figure 3, the motion component includes a moving part 21 and a track 22. The moving part 21 can be a plate, a rod, a block, etc. In this embodiment, the moving part 21 includes a moving block, and the moving block slides in the track 22. Of course, the moving part 21 and the track 22 can be matched in two groups, three groups or more, as needed; and the trigger detection component 3 can be a certain point or a certain section in the movement process of the moving part 21, and is set accordingly according to the different detection principles of different sensors.

[0105] 3 , as the mat material 4 is gradually wound onto the forming roller 5 , the distance between the mat material 4 attached to the forming roller 5 and the mat material 4 that is detached and has a tendency to be wound gradually decreases, and the two together act on the moving part 21 to move the moving part 21 .

[0106] In some embodiments, referring to Figure 3, the moving path of the movable part 21 of the track 22 is set in an arc shape, and the concave portion of the arc faces the side where the forming roller 5 is located, and as the movable part 21 moves, it gradually approaches the forming roller 5 to match the distance change of the two types of wound mats 4, and makes it easier for the mat 4 to enter between the moving block and the forming roller 5, playing a better guiding role; at the same time, it ensures that the mat 4 can drive the movable part 21 to move.

[0107] Taking into account continuous detection, in addition to the situation where it can be reset by gravity, or the moving block has a damping force, referring to Figure 3, in the process of the mat material 4 being pulled back, the moving member 21 will not necessarily return to its original position as the mat material 4 retreats, and there is also a situation where it needs to be reset with the help of external force. Therefore, in order to improve efficiency, reduce human intervention, and the continuity of detection, in some embodiments, the motion component also includes a third reset member 23, and the third reset member 23 includes reset accessories such as a spring and a tension spring. The third reset member 23 is connected to the moving member 21, and plays the effect of resetting the moving member 21 after movement. In addition, the third reset member 23 can enable the moving member 21 to maintain a certain force, avoid erroneous triggering due to vibration or other factors, and improve stability.

[0108] In some embodiments, because there are at least two forming rollers 5, the mat material 4 may be wrapped around any one of the two forming rollers 5. Therefore, the structure in the above embodiment can be set one-to-one to match the number of forming rollers 5 to ensure that all are detected in place.

[0109] 4 to 7 schematically show the structure of a material blockage detection structure according to a fourth embodiment of the present invention.

[0110] 4 to 7 , a paper jam feedback structure includes an upper paper guide 1, a lower paper guide 2, and a detection assembly 3. In addition, the paper jam feedback structure may further include a mounting plate 43, an upper reset mechanism, and a lower reset mechanism.

[0111] 4 and 5 , the upper paper guide 1 and the lower paper guide 2 are distributed vertically, and a channel for discharging the cushion material is formed between the upper paper guide 1 and the lower paper guide 2 .

[0112] 4 to 6, in this embodiment, the upper paper guide 1 is integrally formed with an upper trigger portion 101 on the side along the length direction, and the length of the upper trigger portion 101 is equivalent to the length of the upper paper guide 1, and the upper trigger portion 101 and the upper paper guide 1 are arranged in a bent shape, and the lower paper guide 2 is integrally formed with a lower trigger portion 201 on the side along the length direction, and the length of the lower trigger portion 201 is equivalent to the length of the lower paper guide 2, and the lower trigger portion 201 and the lower paper guide 2 are arranged in a bent shape. In this case, referring to FIG. 6, the upper trigger portion 101 The right end of the trigger portion 101 is higher than the left end of the upper trigger portion 101, and the right end of the lower trigger portion 201 is lower than the left end of the lower trigger portion 201. The distance between the upper trigger portion 101 and the lower trigger portion 201 gradually decreases along the conveying direction of the mat material (from right to left in Figure 6). This arrangement of the upper trigger portion 101 and the lower trigger portion 201 can not only guide the mat material to enter the channel between the upper paper guide 1 and the lower paper guide 2, but also enable the upper trigger portion 101 and the lower trigger portion 201 to flexibly sense the blockage of the mat material. The upper trigger part 101 and the lower trigger part 201 are also arranged in parallel, not only is the guidance of the cushion material into the channel between the upper paper guide 1 and the lower paper guide 2 poor, but also, when the cushion material is blocked between the upper paper guide 1 and the lower paper guide 2, the upper trigger part 101 and the lower trigger part 201 need to be turned at a larger angle to trigger the detection component 3, which makes it easy for more cushion material to be blocked between the upper paper guide 1 and the lower paper guide 2 before it can be detected. The detection component 3 senses it, so, under the premise of guiding the mat material, the distance between the upper trigger part 101 and the lower trigger part 201 gradually decreases along the conveying direction of the mat material (from right to left in Figure 6). In this way, when a small amount of mat material is blocked between the upper paper guide 1 and the lower paper guide 2, the upper trigger part 101 and the lower trigger part 201 can trigger the detection component 3, that is, the upper trigger part 101 and the lower trigger part 201 can trigger the detection component 3 by flipping a smaller angle, thereby ensuring flexible sensing of the mat material blockage.

[0113] 4 and 5, the mounting plate 43 is made of two parts arranged longitudinally, which are respectively located at the two ends of the upper paper guide 1 and the lower paper guide 2. The two ends of the upper paper guide 1 and the lower paper guide 2 are respectively mounted on the mounting plate 43, and the two ends of the upper paper guide 1 are respectively hinged on the mounting plate 43. The two ends of the upper paper guide 1 have the same structure, and the connection structure between the two ends of the upper paper guide 1 and the mounting plate 43 is also the same. The two ends of the lower paper guide 2 are respectively hinged on the mounting plate 43, and the two ends of the lower paper guide 2 have the same structure, and the connection structure between the two ends of the lower paper guide 2 and the mounting plate 43 is also the same. Referring to FIG. 7, the two mounting plates 43 are respectively hinged on the mounting plate 43. The mounting plates 43 are respectively mounted on the equipment body 7 of the mat material forming machine; specifically: a raised upper shaft 431 and a lower shaft 432 are formed on the mounting plate 43, and both ends of the upper paper guide 1 are formed with a first substrate 103 which is arranged vertically with the upper paper guide 1, and a through hole is formed on the first substrate 103, which is close to one side of the upper paper guide 1, and the upper trigger part 101 is close to the other side of the upper paper guide 1, and the upper shaft 431 on the mounting plate 43 is inserted into the through hole on the first substrate 103, and the upper paper guide 1 can rotate around the upper shaft 431, that is, the upper trigger part on the upper paper guide 1 101 can be flipped around the upper shaft 431 located at both ends of the upper paper guide 1, and the two ends of the lower paper guide 2 are formed with a second substrate 203 arranged vertically with the lower paper guide 2. A through hole is formed on the second substrate 203, and the through hole is close to one side of the lower paper guide 2. The lower trigger part 201 is close to the other side of the lower paper guide 2. The lower shaft 432 on the mounting plate 43 is inserted into the through hole on the second substrate 203, and the lower paper guide 2 can rotate around the lower shaft 432, that is, the lower trigger part 201 on the lower paper guide 2 can rotate around the lower shaft 432 located at both ends of the lower paper guide 2. When the cushion material is blocked between the upper paper guide 1 and the lower paper guide 2, the blocked cushion material can lift up the upper trigger part 101 on the upper paper guide 1, and the upper trigger part 101 flips upward with the hinge position of the upper paper guide 1, that is, the upper axis 431 as the center. At the same time, the blocked cushion material can push down the lower trigger part 201 on the lower paper guide 2, and the lower trigger part 201 flips downward with the hinge position of the lower paper guide 2, that is, the lower axis 432 as the center. The upper trigger part 101 and the lower trigger part 201 move away from each other until the upper trigger part 101 and the lower trigger part 201 trigger the detection component 3 respectively.

[0114] 4 and 7 , in this embodiment, there are two detection components 3. One detection component 3 is mounted on the equipment body 7 of the mat material forming machine through the first mounting bracket 44. The detection component 3 is located above the upper trigger portion 101. The other detection component 3 is mounted on the equipment body 7 of the mat material forming machine through the second mounting bracket 45. The detection component 3 is located below the lower trigger portion 201. When the upper trigger portion 101 and the lower trigger portion 201 are away from each other, the upper trigger portion 101 and the lower trigger portion 201 can respectively trigger the corresponding detection components 3. In this embodiment, the detection component 3 can use a proximity switch or a contact switch. Specifically, the detection component 3 can A micro switch is selected. For the micro switch above the upper trigger portion 101, the contacted portion 31 of the micro switch is fixed on the micro switch. When the upper trigger portion 101 contacts the contacted portion 31, the micro switch can be triggered. The installation method of the micro switch below the lower trigger portion 201 is the same as the installation method of the micro switch above the upper trigger portion 101, that is, the contacted portion of the micro switch is also installed on the micro switch. Among them, the contacted portion 31 of the micro switch can be in the form of a column, a spring, a rod, etc., as long as it can be ensured that when the upper trigger portion 101 and the lower trigger portion 201 are away from each other, the upper trigger portion 101 and the lower trigger portion 201 can trigger the micro switch respectively. In other embodiments, the detection component 3 can also use a distance sensor, a displacement sensor or a pressure sensor, as long as it can be ensured that when the upper trigger portion 101 and the lower trigger portion 201 are away from each other, the upper trigger portion 101 and the lower trigger portion 201 can trigger the detection component 3 respectively.

[0115] Referring to Figure 5, an upper limit hole 102 is formed on the first substrate 103 of the upper paper guide 1, and the upper limit hole 102 is in the shape of a long hole and slightly curved. An upper limit rod 41 is formed on the mounting plate 43 on the equipment body 7 of the mat material forming machine, and the upper limit rod 41 is inserted into the upper limit hole 102 and can move in the upper limit hole 102. A lower limit hole 202 is formed on the second substrate 203 of the lower paper guide 2, and the lower limit hole 202 is in the shape of a long hole and slightly curved. A lower limit hole 202 is formed on the mounting plate 43 on the equipment body 7 of the mat material forming machine. The limit rod 42 is inserted into the lower limit hole 202 and can move in the lower limit hole 202; the cooperation between the upper limit hole 102 and the upper limit rod 41 can limit the flipping angle of the upper trigger part 101, and the cooperation between the lower limit hole 202 and the lower limit rod 42 can limit the flipping angle of the lower trigger part 201. When the mat material is not blocked, the upper limit rod 41 is located at one end of the upper limit hole 102 (the state shown in Figure 5), and the lower limit rod 42 is located at one end of the lower limit hole 202 (the state shown in Figure 5). When the mat material is blocked When blocked, the upper trigger portion 101 is turned upward with the hinged position of the upper paper guide 1, i.e., the upper shaft 431, as the center and moves relatively to the upper limit rod 41 in the upper limit hole 102. The lower trigger portion 201 is turned downward with the hinged position of the lower paper guide 2, i.e., the lower shaft 432, as the center and moves relatively to the lower limit rod 42 in the lower limit hole 202. The upper trigger portion 101 and the lower trigger portion 201 move away from each other. When the upper limit rod 41 moves to the other end of the upper limit hole 102, the upper trigger portion 101 just contacts the contacted portion 31 on the micro switch. , thereby triggering the micro switch, and due to the existence of the upper limit rod 41, the upper trigger part 101 cannot continue to flip upward at this time. At the same time, when the lower limit rod 42 moves to the other end in the lower limit hole 202, the lower trigger part 201 just contacts the contacted part on the micro switch, thereby triggering the micro switch, and due to the existence of the lower limit rod 42, the lower trigger part 201 cannot continue to flip downward at this time, which can prevent the upper trigger part 101 and the lower trigger part 201 from further squeezing the micro switch and damaging the detection component 3.

[0116] Referring to Figure 6, an upper flap 111 is formed at the right end of the upper trigger part 101, and a lower flap 211 is formed at the right end of the lower trigger part 201. The upper flap 111 and the lower flap 211 can prevent the formed pad material from entering the upper part of the upper trigger part 101 and the lower part of the lower trigger part 201. In addition, after the paper is jammed, the staff usually pulls the jammed paper out by hand, but the jammed pad material may be wound up by the forming roller, and the protrusions on the pad material may be stuck on the edge of the upper trigger part 101 and the edge of the lower trigger part 201. By setting the upper flap 111 and the lower flap 211, the pad material can be prevented from getting stuck on the edges of the upper trigger part 101 and the lower trigger part 201 when the staff is pulling out the jammed paper.

[0117] 4 , 6 and 7 , an upper reset mechanism is installed above the upper paper guide 1, and a lower reset mechanism is installed below the lower paper guide 2. When the pad material blocking between the upper paper guide 1 and the lower paper guide 2 is removed, the upper reset mechanism can drive the upper trigger portion 101 close to the lower trigger portion 201 to reset the upper trigger portion 101 (the state shown in FIG4 ), and the lower reset mechanism can drive the lower trigger portion 201 close to the upper trigger portion 101 to reset the lower trigger portion 201 (the state shown in FIG4 ). Specifically: Referring to Figures 4 and 7, the upper reset mechanism includes an upper mounting frame 501, an upper reset column 502 and an upper reset spring 503. The upper mounting frame 501 is hung on the upper beam 71 of the equipment body 7 of the mat material forming machine. The bottom of the upper mounting frame 501 is formed with an upper long hole 5011. One end of the upper reset column 502 is fixed to the upper trigger part 101, and the other end of the upper reset column 502 is inserted into the upper long hole 5011. The upper reset spring 503 is sleeved on the upper reset column 502. When no mat material is blocked, The upper return spring 503 is in a non-stretched state, and the lower return mechanism includes a lower mounting frame 601, a lower return column 602 and a lower return spring 603. The bottom of the lower mounting frame 601 is mounted on the lower beam 72 of the equipment body 7 of the mat material forming machine. The top of the lower mounting frame 601 is formed with a lower long hole 6011. One end of the lower return column 602 is fixed on the lower trigger part 201, and the other end of the lower return column 602 is inserted into the lower long hole 6011. The lower return spring 603 is sleeved on the lower return column 602, and no mat occurs. When the material is blocked, the lower return spring 603 is in a non-stretched state. When the pad material is blocked between the upper paper guide 1 and the lower paper guide 2, the blocked pad material pushes up the upper trigger part 101, and the upper trigger part 101 drives the upper return column 502 to move synchronously. The upper return spring 503 on the upper return column 502 is compressed. At the same time, the blocked pad material pushes the lower trigger part 201 downward, and the lower trigger part 201 drives the lower return column 602 to move synchronously. The lower return spring 603 on the lower return column 602 is compressed, and the upper trigger part 1 01 and the lower trigger part 201 move away from each other. When the cushion material blocking between the upper paper guide 1 and the lower paper guide 2 is removed, the upper trigger part 101 and the lower trigger part 201 automatically reset under the restoring force of the upper reset spring 503 and the lower reset spring 603, and the upper trigger part 101 and the lower trigger part 201 move closer to each other. That is, the upper paper guide 1 together with the upper trigger part 101 and the lower paper guide 2 together with the lower trigger part 201 are automatically reset as a whole (the state shown in Figures 4 and 7), preparing for the subsequent production of cushion material. In addition, the upper reset mechanism can be installed in the middle of the upper paper guide 1 or at a position near both ends of the upper paper guide 1, and the lower reset mechanism can be installed in the middle of the lower paper guide 2 or at a position near both ends of the lower paper guide 2.In other embodiments, the upper reset mechanism may be a spring installed between the upper trigger portion 101 and the upper beam 71 of the mat material forming machine's main body 7. When no mat material blockage occurs, the spring is in a non-stretched state. The lower reset mechanism may be a spring installed between the lower trigger portion 201 and the lower beam 72 of the mat material forming machine's main body 7. When no mat material blockage occurs, the spring is in a non-stretched state. In other embodiments, a torsion spring structure may be installed on each of the upper shaft 431 and the lower shaft 432 of the mounting plate 43 to achieve automatic reset of the upper paper guide 1 together with the upper trigger portion 101 and the lower paper guide 2 together with the lower trigger portion 201.

[0118] In other embodiments, the upper paper guide 1 and the lower paper guide 2 may not be a whole structure. The upper paper guide 1 can be divided into multiple pieces arranged in series. One end of the two upper paper guides 1 located on the two most sides is hinged on a mounting plate 43. The two adjacent upper paper guides 1 are installed on the equipment body 7 of the mat material forming machine through a hanger. The upper paper guide 1 and the hanger are also hingedly connected. The top of the hanger is fixed on the equipment body 7 of the mat material forming machine. The bottom of the hanger is flush with the bottom of the upper paper guide 1, ensuring that all areas below the upper paper guide 1 are connected in the length direction of the upper paper guide 1, without affecting the discharge of the mat material. The structure of each upper paper guide 1 is the same. A detection component 3 is installed above each upper paper guide 1. Each upper paper guide 1 is installed above an upper reset mechanism, the lower paper guide 2 can be divided into multiple blocks arranged in series, one end of the two lower paper guides 2 located on the two most sides is hinged on a mounting plate 43, and the two adjacent lower paper guides 2 are installed on the equipment body 7 of the mat material forming machine through a hanger, the lower paper guide 2 and the hanger are also hingedly connected, the top of the hanger is flush with the top of the lower paper guide 2, and the bottom of the hanger is fixed on the equipment body 7 of the mat material forming machine, ensuring that the area above all lower paper guides 2 is connected in the length direction of the lower paper guide 2, without affecting the discharge of the mat material, each lower paper guide 2 has the same structure, a detection component 3 is installed below each lower paper guide 2, and a lower reset mechanism is installed below each lower paper guide 2.

[0119] In other embodiments, both ends of the lower paper guide 2 can also be directly fixed on the mounting plate 43 on the equipment body 7 of the mat material forming machine, and the upper paper guide 1 is installed on the mounting plate 43 on the equipment body 7 of the mat material forming machine in the manner of FIG7 , and the detection component 3 is installed only above the upper guide plate 1. When the mat material is blocked, the lower paper guide 2 and the lower trigger part 201 do not flip over, and the blocked mat material only lifts up the upper trigger part 101. The detection component 3 above the upper guide plate 1 senses and feeds back the paper jam. In this case, when the mat material is blocked, the upper trigger part 101 is away from the lower trigger part 201, and the upper reset mechanism does not need to be installed above the upper paper guide 1. No lower reset mechanism is installed under the lower paper guide 2. When the cushion material blocking between the upper paper guide 1 and the lower paper guide 2 is removed, the upper trigger part 101 relies on its own weight to approach the lower trigger part 201, thereby realizing the overall reset of the upper paper guide 1 together with the upper trigger part 101.
