Description

Technical Field

[0001] This utility model relates to the field of pressure detection components, conveying devices and processing devices, and in particular to a pressure detection component, conveying device and processing device. Background Technology

[0002] As modern industry continues to evolve and processing equipment is constantly being innovated, when processing equipment is equipped with a conveyor device, longer processing materials can be transported into the processing equipment, increasing the processing size range of the equipment.

[0003] Because the thickness of each piece of material varies, the conveyor system lacks a pressure display when the user is clamping the material. This prevents the user from intuitively understanding the clamping level, necessitating constant adjustment. Even after adjustment, the clamping force may still be too low or too high. Insufficient pressure can easily cause material slippage and offset during transport, negatively impacting the processing results of the laser processing equipment. Conversely, excessive pressure increases resistance during material transport, slowing the conveyor speed and potentially causing malfunctions in the drive motor, damaging its performance and ultimately affecting the processing effect of the laser processing equipment.

[0004] Pressure detection components typically use the compression of a spring within the component to move a color indicator block up and down, while the display window remains fixed, showing the color of the indicator block through the window. When the conveyor presses the material being processed, the amount of spring compression corresponds to the amount the color indicator block moves upward. Since the size of the different colors on the indicator block is set based on the spring compression, and the size of the color display window is also limited by the color on the indicator block, a window that is too small will be inconvenient for the user to observe.

[0005] Chinese Patent Publication No. CN220772406U relates to a pressure detection component, a workpiece conveying device, and a computer numerical control (CNC) machine. The pressure detection component is applied to the workpiece conveying device of a CNC machine to detect the pressure exerted on the workpiece during conveying. The pressure detection component includes: a fixed component for connection to the workpiece conveying device; a detection component connected to the fixed component for detecting the pressure on the workpiece; and a display unit disposed on the fixed component and / or the detection component, which displays pressure information. The detection component displays the detected pressure information on the display unit. By installing a pressure detection component on the workpiece conveying device, the user can be alerted in real time to the pressure exerted on the workpiece during conveying. Based on the pressure information, the user can adjust the pressure exerted on the workpiece by the conveying device to keep the pressure within a reasonable range. However, the display unit in this patent is located on the fixed component, resulting in a small display window. Furthermore, small upward movements may not be displayed on the window, leading to incorrect judgment of the clamping force and affecting subsequent processing results. Utility Model Content

[0006] The technical problem this invention aims to solve is that pressure detection components typically use the compression of a spring within the component to move a color indicator block up and down, while the display window remains fixed, displaying the color of the indicator block through the window. When the conveying device presses the material being processed, the amount of spring compression in the component corresponds to the amount of upward displacement of the color indicator block. Since the size of the different colors on the indicator block is set based on the spring compression, and the size of the color display window is also limited by the color on the indicator block, a window that is too small is inconvenient for the user to observe. To address the above-mentioned deficiencies of the prior art, this invention provides a pressure detection component, a conveying device, and a processing device.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A pressure detection component is constructed, including a lifting plate. At least one set of clamping rollers is disposed under the lifting plate. The clamping rollers can move upward or downward relative to the lifting plate. A first push block and a second push block are disposed inside the lifting plate. The first push block and the second push block move upward or downward synchronously with the clamping rollers. A clamping force marking block is disposed between the first push block and the second push block. The first push block moves in a first direction along the Z-axis, pushing the clamping force marking block to move in a first horizontal direction. The second push block moves in a second direction along the Z-axis, pushing the clamping force marking block to move in a second horizontal direction.

[0009] The pressure detection component described above moves the pressure roller assembly in the first direction of the Z-axis. The first push block and the second push block move synchronously upward or downward with the pressure roller assembly in the Z-axis direction. The movement of the first push block or the second push block in the Z-axis direction pushes the pressure indicator block to move in the horizontal direction. This converts the movement of the pressure roller assembly in the Z-axis direction into the movement of the pressure indicator block in the X-axis direction. The pressure indicator block's movement in the X-axis direction displays different proportions of pressure, thus revealing the movement of the pressure roller assembly in the Z-axis direction.

[0010] Preferably, the first push block and the second push block move upward or downward synchronously with the pressure wheel assembly, the pressure force indicator block is provided with different color indicators, and the lifting plate is provided with an indicator window corresponding to the color indicator.

[0011] Preferably, the first Z-axis direction is opposite to the second Z-axis direction, the first horizontal direction is opposite to the second horizontal direction, and the first push block and the second push block contact the clamping force indicator block through inclined surfaces, causing the first push block and the second push block to push the color indicator block to move.

[0012] Preferably, a spring is provided between the pressing wheel assembly and the lifting plate. When the pressing wheel assembly moves toward the lifting plate under force, the spring is compressed. After the pressing wheel assembly is released from force, the spring resets and pushes the pressing wheel assembly away from the lifting plate.

[0013] Preferably, the clamping wheel assembly includes a stud, a roller seat is connected below the stud, a roller is provided on the roller seat, a spring is sleeved on the outside of the stud, the roller can move relative to the lifting plate to compress the spring, and return to its original position under the action of the spring.

[0014] A conveying device is constructed, including a conveying platform and side end caps disposed on both sides of the conveying platform. A lifting assembly is connected to the upper end of the side end caps. Multiple sets of conveying rollers are disposed on the conveying platform corresponding to the lifting assembly. The lifting assembly includes a lifting fixing plate disposed on the upper end of the side end caps. A pressure detection assembly as described above is disposed below the lifting fixing plate. The lifting fixing plate and the lifting plate are connected by a lifting device, and the movement of the lifting plate is controlled by the lifting device to drive the movement of the pressure roller set. The pressure roller set is disposed corresponding to the conveying rollers. The workpiece to be processed is conveyed through the pressure roller set and the conveying rollers.

[0015] Preferably, the lifting device is configured as two sets and placed on both sides of the lifting fixed plate. The two sets of lifting devices are connected by a synchronous belt and maintain synchronous movement. A knob is provided above one or both sets of lifting devices. The knob is used to rotate the lifting device and drive the pressure detection component to move up and down.

[0016] Preferably, the multiple sets of conveyor rollers are connected by conveyor roller shafts to keep the multiple sets of conveyor rollers rotating synchronously, and a conveyor knob is provided on the outside of the conveyor platform corresponding to the conveyor rollers.

[0017] Preferably, the conveying platform may also be equipped with a motor, and at least one side of the conveyor wheel shaft is equipped with a synchronous pulley corresponding to the motor. The synchronous pulley is connected to the motor through a synchronous belt, and the conveyor wheel shaft can be rotated by the motor or manually.

[0018] A processing device is constructed, including the conveying device as described above. The conveying device is equipped with a processing head. The conveying device is used to transport the workpiece to be processed to the processing head for processing and to transport the processed workpiece to the next process. Two sets of support frames are provided on both the left and right sides of the conveying device.

[0019] The beneficial effects of this invention are as follows: By installing a pressure detection component in the conveying device, when the conveying device presses down on the processed material, the pressure detection component will display different colors according to the degree of pressing down. Users can adjust the pressing force based on the displayed color to ensure the pressing force on the processed material is within a reasonable range. The pressure detection component is slidable left and right for easy observation, and the angle of the push block inside the component can be adjusted for more accurate reflection of the pressing degree of the conveying device. To allow customers to more intuitively understand the pressing force of the conveying device and quickly adjust it, the pressure detection component displays the pressure on the conveying device, with different colors representing different degrees of pressing.

[0020] To avoid limiting the display window, the pressure testing component changes the color indicator block's vertical display to a horizontal movement display. The angle of the push block within the component can be adjusted to regulate the ratio of vertical and horizontal movement. This eliminates limitations on the color size of the indicator block, and the display window size can also be adjusted for easier user observation. Furthermore, adjusting the ratio of vertical and horizontal movement allows for a more sensitive and accurate reflection of the conveyor's compression level. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] A preferred embodiment of the present invention includes a pressure detection component, a conveying device, and a processing device; such as... Figure 1As shown, the processing device includes a conveying device 1 and support frames 2 arranged on both sides of the conveying device 1. The support frames 2 convey the work to be processed to the conveying device 1 and also convey the processed work. There are two sets of support frames 2, and both sets of support frames 2 are connected to the conveying device 1 from the left and right sides by connecting parts. The support frames 2 can also be adjusted according to the length of the work to be processed. This processing device can be used for laser cutting with laser cutting equipment, laser engraving with laser engraving equipment, laser marking with laser marking equipment, and knife cutting with knife cutting equipment, etc. The work to be processed is conveyed through the conveying device 1, and then the processing head is set on the conveying device 1. When the work to be processed is conveyed to the conveying device 1, it is processed by the processing head, and then the processed work is conveyed to the next process through the conveying device 1. All of these should fall within the protection scope of this utility model patent. In this application, laser engraving with laser engraving equipment is specifically used as an example for illustration.

[0035] Specifically, such as Figure 2-3 As shown, the conveying device 1 includes a conveying platform 101, on which a hook can be installed to connect and fix with a laser device, and side end caps 104 on the left and right sides of the conveying platform 101. A lifting assembly is connected above the side end caps 104. The lifting assembly includes a lifting fixing plate 108 on the upper end of the side end caps 104, and a lifting plate 116 is movably connected below the lifting fixing plate 108. Multiple sets of clamping rollers 118 are provided at the lower end of the lifting plate 116. At the same time, a lifting device 115 is fixed on the lifting plate 116. The lifting plate 116 is raised and lowered by rotating the lifting device 115, which drives the clamping rollers 118 to rise and fall. A conveying roller 107 is provided on the conveying platform 101 corresponding to the clamping rollers. A gap for conveying the work to be processed is left between the clamping rollers 118 and the conveying rollers 107. The size of the gap changes with the up and down movement of the clamping rollers 118, thereby realizing the clamping, conveying and processing of materials of different thicknesses. To keep the materials to be processed flat when entering the conveyor platform 101, an upper pressure shaft 103 is provided on one side of the conveyor platform 101, and a support shaft 106 is provided below the upper pressure shaft 103. Both the support shaft 106 and the upper pressure shaft 103 are fixed by side end caps 104, and a gap is also left between the support shaft 106 and the upper pressure shaft 103. This gap can be adjusted as needed to ensure that the materials to be processed remain flat when entering the conveyor platform 101, which facilitates the subsequent conveying and processing of the materials.

[0036] Furthermore, such as Figure 3-4As shown, to enable automatic material conveying, multiple sets of conveyor rollers 107 are connected by a conveyor shaft 110. The conveyor shaft 110 causes the multiple sets of conveyor rollers 107 to rotate synchronously. A conveyor knob 114 is provided on one side of each conveyor roller 107, and a synchronous pulley 113 is sleeved on the conveyor shaft 110. A motor 111 and a first synchronous belt 112 are provided inside the conveyor platform 101 corresponding to the synchronous pulley 113. The first synchronous belt 112 connects the synchronous pulley 113 and the motor 111, enabling the motor 111 to drive the synchronous pulley 113 to rotate. Alternatively, synchronous pulleys 113 can be provided on both sides of the conveyor shaft 110, along with a motor 111 and a first synchronous belt 112. After the material is pressed, the conveyor knob 114 can be manually rotated to drive the conveyor rollers 107 on the conveyor shaft 110 to rotate. The conveyor rollers 107 are provided with knurled texture, and the friction between the knurled texture and the surface of the material to be processed drives the material to move forward. To ensure the smooth transport of the material to be processed, the pressure roller group 118 can be adjusted to move downwards to change the pressure between the pressure roller group 118 and the conveyor roller 107, so that the friction is large enough but will not damage the material to be processed. After the material to be processed is transported forward to a suitable position, the motor 111 is activated. The motor 111 drives the first synchronous belt 112 to rotate, which in turn drives the synchronous belt pulley 113 to rotate. The rotation of the synchronous belt pulley 113 drives the conveyor shaft 110 to rotate, thereby realizing the rotation of the conveyor roller 107. This realizes the automatic transport of the material to be processed to the laser equipment for processing, improving the stability of the material to be processed during the transport and processing process.

[0037] Furthermore, such as Figure 5-6 As shown, lifting devices 115 are provided on both sides of the lifting fixed plate 108. The two sets of lifting devices rotate synchronously inside the lifting fixed plate 108 via a second synchronous belt 117. The lifting devices 115 are connected to the lifting plate 116 via a screw nut 122, and the rotation of the lifting devices 115 causes the screw nut 122 to move up and down, thereby driving the lifting plate 116 to move up and down. The rotation of the lifting devices can be controlled by a knob or electric drive. Only one set of lifting devices 115 needs to be equipped with a knob. Since the knob is located at either end or both ends of the lifting fixed plate, adjustment of the lifting devices 115 can be achieved without walking, making adjustment more convenient. Furthermore, the two sets of lifting devices 115 are connected by the second synchronous belt 117, allowing both sides of the lifting plate 116 to rise and fall simultaneously, avoiding errors caused by unilateral lifting of the lifting devices 116. At the same time, because both sides of the lifting plate 116 rise and fall simultaneously, multiple sets of pressure rollers 118 rise and fall simultaneously, ensuring that the distance between each set of pressure rollers 118 and the conveyor roller 107 is the same.

[0038] Furthermore, such as Figure 5-8As shown, the clamping wheel assembly 118 includes a pressure plate 1181 fixedly connected to the lifting plate 116, and a double-through stud 1182 disposed below the pressure plate 1181. A roller seat 1185 is connected to the lower end of the double-through stud 1182. A roller 1186 is mounted on the roller seat 115, secured with screws after a pin is inserted, allowing the roller 1186 to rotate on the roller seat 1185. A spring 1184 is sleeved on the double-through stud 1182, positioned between the lifting plate 116 and the roller seat 1185. When the lifting plate 116 descends to clamp the material to be processed, the entire clamping wheel assembly 118 will be subjected to a reaction force and move upwards, while the spring 1185 will be compressed. When the lifting plate 116 rises, the spring 1184 will return to its original position, simultaneously resetting the clamping wheel assembly 118.

[0039] Furthermore, such as Figure 5 and Figure 8-11As shown, an indicator window 1160 is provided on the lifting plate 116, and a color indicator block 120 is provided inside the lifting plate 116. A left push block 119 is provided on the left side of the color indicator block, and a right push block 121 is provided on the right side. The left push block 119 and the right push block 121 are both fixed to the adjacent pressure roller assembly 118 by screws. Different indicator marks 1200 are silkscreened on the color indicator block 120. In this application, different colors can be used to represent different indicator marks 1200. Meanwhile, the contact surfaces of the left push block 119, color indicator block 120, and right push block 121 are all set as inclined surfaces at a certain angle, and the inclined surfaces are parallel to each other to form an inclined contact surface. The indicator 1200 is placed at the indicator window 1160. Since the left push block 119 and right push block 121 are both set with inclined surfaces, when the left push block 119 and right push block 121 move up and down, they will push the color indicator block 120 to move left and right, thereby realizing the left and right movement of the color indicator 1200 at the indicator window 1160. By displaying different colors on the display window, the user can adjust the clamping force of the conveying device according to the color at the window. At the same time, due to the setting of the inclined surfaces, when the clamping wheel group 118 only moves up and down a small distance, the inclined surfaces enable the color indicator block 120 to move a larger distance in the left and right direction, making it easier to observe the movement distance. It should be noted that the color indicator block 120 moves left and right within the lifting plate 116. The ratio of the vertical movement distance of the pressure roller assembly 118 to the horizontal movement distance of the color indicator block 120 can be changed according to the angle of the inclined surface. The specific angle setting is not detailed in this application, but should all fall within the protection scope of this utility model. Meanwhile, an upper baffle 1211 is provided above the right push block 121 for limiting its movement. Furthermore, to prevent the color indicator block from moving upwards when the left push block 119 and right push block 121 move upwards due to the irregular shape of the inclined surface during processing, an elastic element (not shown in the figure) can be provided above the color indicator block. This elastic element provides downward pressure to the color indicator block, ensuring that it can only move horizontally. Under normal circumstances, due to gravity, the color indicator block can only move horizontally as well. Alternatively, the left push block 119 and the right push block 121 can be set on any two sets of pressure rollers 118. In this case, the color indicator block 120 is longer, but it can still provide color indication. However, the longer color indicator block will result in a larger weight, which will cause greater pressure on the left push block 119 or the right push block 121, increasing the resistance to the upward movement of the pressure rollers. Therefore, it is more appropriate to set it on two adjacent sets of pressure rollers 120.

[0040] When the conveying device 1 begins to press the material to be processed, turning the knob causes the lifting device 115 to rotate, causing the lifting plate 116 to move downwards and drive the pressing wheel assembly 118 to contact the material to be processed downwards. The material to be processed will be subjected to the downward pressing force of the pressing wheel assembly 118, and the pressing wheel assembly 118 will be subjected to an upward force under the reaction of the pressing force. At this time, the spring 1184 inside the pressing wheel assembly 118 is compressed, and the pressing wheel assembly 118 will move upwards. The left push block 119 and the right push block 121 will also move upwards with the pressing wheel assembly 118. At this time, the left inclined surface 1 of the right push block... When 210 contacts the right inclined surface 1202 of the color indicator block, the force exerted by the right push block 121 on the color indicator block 120 is decomposed into upward and leftward forces through the left inclined surface 1210 of the right push block. Since the color indicator block 120 is restricted upward and subjected to downward gravity, it will move to the left. The indicator mark 1200 on the color indicator block 120 will be displayed through the indicator window 1160 on the lifting rod 116. The user can clearly see the color on the color indicator block 120 through the indicator window 1160, thereby judging the current clamping force.

[0041] When the conveying device 1 releases the material to be processed, the lifting plate 116 moves upward, causing the pressure roller assembly 118 to move away from the material to be processed. At the same time, under the action of the spring 1184, the pressure roller assembly 118 resets, causing the pressure roller assembly 118 to move downward relative to the lifting plate 116. At this time, the left push block 119 and the right push block 121 also move downward with the pressure roller assembly 118. The left push block 119 contacts the color indicator block 120. Since the contact surface between the left push block 119 and the color indicator block 120 is an inclined plane, the force exerted by the left push block 119 on the color indicator block 120 is decomposed into downward and rightward forces through the inclined plane. Since the downward movement of the color indicator block 120 is restricted, it will move to the right. When the pressure roller assembly 118 is completely away from the material to be processed, the color indicator block 120 will return to its initial position and be displayed in the indicator window 1160.

[0042] It should be noted that in this application, the right side of the left push block 119 is configured to push the color indicator block 120 to the right when moving downwards, but not when moving upwards. Alternatively, the right side of the left push block 119 can be configured to push the color indicator block 120 to the right when moving upwards, but not when moving downwards. No specific limitation is made here. However, it should be noted that if the left push block 119 pushes the color indicator block 120 to the right when moving upwards in the Z-axis direction, it will not push the color indicator block 120 when moving downwards in the Z-axis direction. Or, if the left push block 119 pushes the color indicator block 120 to the right when moving downwards in the Z-axis direction, it will not push the color indicator block 120 when moving upwards in the Z-axis direction. That is, if the left push block 119 pushes the color indicator block 120 to the right when moving in one direction of the Z-axis, it will not push the color indicator block 120 when moving in the opposite direction of the Z-axis. The pushing situation of the right push block 121 is exactly the opposite of that of the left push block 119, which will not be repeated here.

[0043] It should be understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
