Description

Technical Field

[0001] The present invention relates to the technical field of blood drawing chair processing, and in particular to a blood drawing chair support plate cutting device. Background Art

[0002] In the design and production process of medical equipment and blood collection facilities, the stability and comfort of the blood collection chair, as an important medical auxiliary equipment, are crucial to both patients and medical staff. In the production process of the blood collection chair, a support plate is required. As a key component of the blood collection chair, the support plate not only needs to have sufficient strength and stability to support the weight of the entire chair and the weight of the patient, but also needs to be cut before use so that the support plate reaches the required shape.

[0003] The Chinese patent with announcement number CN112620790B discloses an energy-saving cutting device for seat panels, including a base, the bottom of which is fixedly mounted with four uprights, the four uprights being symmetrically arranged in pairs, the top of the base being provided with a slide groove, the slide groove being provided with a screw rod, the screw rod being provided with a slide seat on a threaded sleeve, the top of the slide seat extending out of the slide groove and being fixedly mounted with a platform, the top of the platform being provided with a groove, both sides of the groove being open structures. Although the above patent can cut the support plate of the blood collection chair, due to the fixed nature of the platform and the splint, the support plate can only be cut once at a time, and the cutting position is usually centered. This means that after each cut, the machine needs to be manually stopped to adjust the position of the support plate before the next cut is made. This mode of operation is not only cumbersome, but also seriously affects the cutting efficiency.

[0004] The present invention aims to solve the problems existing in the above patents. To this end, a blood collection chair support plate cutting device is proposed, which can continuously and stably cut the support plate without stopping for adjustment, is easy to operate, and improves cutting efficiency. Summary of the Invention

The driving assembly is used to first drive the control valve 12 to rotate ninety degrees so that the adsorption head 7 stops sucking the support plate, and then drives the adsorption head 7 to move downward to the fixed frame 6 to retract, so that the adsorption head 7 in the cutting area loses its support for the support plate, and then the electric cutting machine 31 performs continuous cutting on the support plate at any position.

[0030] See also Figure 3-Figure 5As shown, the driving assembly includes a hollow iron rod 9, a return spring 91, an electromagnet 92, a U-shaped plate 93 and a transmission assembly. The bottom of the adsorption head 7 is symmetrically fixed with a U-shaped plate 93. The bottom of the fixed frame 6 and the bottom of the electric rotating frame 5 are slidably connected with a hollow iron rod 9. The hollow iron rod 9 is located between the left and right U-shaped plates 93. When the hollow iron rod 9 moves downward and contacts the U-shaped plate 93, the hollow iron rod 9 can drive the U-shaped plate 93 to move downward, so that the adsorption head 7 moves downward. The hollow iron rod 9 is sleeved on the hose 10. The hollow iron rod 9 is between the lower part of the hollow iron rod 9 and the outer bottom of the electric rotating frame 5. A return spring 91 is connected, and an electromagnet 92 is embedded and fixed on the front top side of the base 1. The electromagnet 92 is located below the hollow iron rod 9.

[0031] See also Figure 6 and Figure 7 As shown, the blood collection chair support plate cutting device also includes a closing component installed between the adsorption head 7 and the fixed frame 6, the closing component includes a sealing frame 13, a sealing plate 131, a connecting spring 132 and a blocking component, the top of the fixed frame 6 is fixedly connected to the sealing frame 13, and the sealing frame 13 is symmetrically rotated front and back and connected to the sealing plate 131, the sealing plate 131 is in contact with the adsorption head 7, and when the sealing plate 131 swings inward, the sealing plate 131 can seal the inside of the sealing frame 13 to complete the sealing of the fixed frame 6, and the sealing plates 13 on the front and rear sides are connected. 1 is symmetrically connected with a connecting spring 132, and a blocking component is provided on the adsorption head 7, which can block the inside of the adsorption head 7; the blocking component includes a contact frame 133, a compression spring 134 and a blocking block 135, the top of the adsorption head 7 is slidably connected with the contact frame 133, a compression spring 134 is connected between the bottom of the contact frame 133 and the inner side of the adsorption head 7, and a blocking block 135 is fixed in the middle of the bottom of the contact frame 133, and the blocking block 135 is located on the inner side of the suction end of the adsorption head 7, and the blocking block 135 can block the inside of the adsorption head 7.

[0032] Initially, the hollow disk 8 is connected to an external vacuum pump. First, the support plate required for making the blood collection chair is placed on the adsorption head 7, and then the external vacuum pump is started to evacuate the hollow disk 8. The hollow disk 8 then evacuates the adsorption head 7 through the hose 10, so that the adsorption head 7 is in a negative pressure state, and the adsorption head 7 adsorbs and fixes the support plate. Then, the electric transverse moving seat 4 is started to drive the electric rotating frame 5 to move left and right. The electric rotating frame 5 drives the adsorption head 7 to move left and right through the fixed frame 6, and the adsorption head 7 drives the support plate to move left and right. When the support plate moves left and right so that the cutting position corresponds to the electric cutting machine 31, the electric transverse moving seat 4 is turned off, and the electric rotating frame 5 can be started to rotate. The electric rotating frame 5 drives the support plate to rotate through the fixed frame 6 and the adsorption head 7 to adjust the support plate. The cutting angle is adjusted, the electric rotating frame 5 is closed, and then the electromagnet 92 is started. The electromagnet 92 attracts the corresponding hollow iron rod 9 to move downward through magnetic force, and the reset spring 91 is stretched. The hollow iron rod 9 moves downward to drive the rack 95 to move downward, and the rack 95 moves downward to drive the spur gear 94 to rotate forward ninety degrees. The spur gear 94 drives the control valve 12 to rotate forward ninety degrees. The control valve 12 rotates forward ninety degrees to close the adsorption head 7, and the negative pressure state in the adsorption head 7 is lost. The adsorption head 7 stops sucking and fixing the support plate, and then the hollow iron rod 9 continues to move downward and contacts the U-shaped plate 93. The hollow iron rod 9 moves downward to drive the U-shaped plate 93 to move downward. The U-shaped plate 93 drives the adsorption head 7 to move downward into the fixed frame 6 and retract, and the support spring 11 is compressed. The raised adsorption head 7 does not affect the cutting of the support plate by the electric cutting machine 31. The remaining adsorption heads 7 that do not correspond to the electromagnet 92 continue to adsorb and fix the support plate, and then the electric cutting machine 31 is started, and then the electric moving plate 2 is started to move forward to drive the electric cutting machine 31 to move forward. The electric cutting machine 31 moves forward to cut the support plate. After the support plate is cut once, the electric moving plate 2 is started to drive the electric cutting machine 31 to move backward and reset. The electric moving plate 2 and the electric rotating frame 5 are started to drive the support plate to rotate and move through the adsorption head 7 to adjust the subsequent cutting position. At the same time, the hollow iron rod 9 is driven to move and rotate by starting the electric moving plate 2 and the electric rotating frame 5. The hollow iron rod 9 corresponding to the electromagnet 92 moves and rotates and is decoupled from the electromagnet 92. When the cam 93 is out of contact, due to the action of the return spring 91, the hollow iron rod 9 moves upward and resets, driving the rack 95 to move upward and reset. The rack 95 resets and drives the spur gear 94 to reverse 90 degrees and reset. The spur gear 94 reverses 90 degrees and stops to seal the adsorption head 7. The hose 10 evacuates the adsorption head 7 through the control valve 12, so that the adsorption head 7 is in a negative pressure state. Then the hollow iron rod 9 continues to move upward and disengages from the U-shaped plate 93. Due to the action of the support spring 11, the adsorption head 7 moves upward and resets to continue to contact the support plate. The adsorption head 7 sucks the support plate and fixes it. When the position adjustment of the support plate is completed, the adsorption head 7 in the cutting area is retracted in the fixed frame 6 without affecting the cutting. The above operation can be repeated to continue cutting the support plate.The suction head 7 in the area corresponding to the electric cutter 31 can be moved downward to disengage from the support plate, allowing for continuous cutting of the support plate without requiring downtime for adjustment. This facilitates operation and improves cutting efficiency. When the support plate is cut into the desired shape, the electric cutter 31 and the external vacuum pump are turned off, removing the negative pressure in the suction head 7 and stopping it from holding the support plate in place. The cut support plate can then be removed from the suction head 7 for subsequent use. The block 135 stops blocking the suction end of the adsorption head 7 and then starts cutting, and the adsorption head 7 adsorbs the support plate. When the support plate is adjusted to the cutting position, the adsorption head 7 in the cutting area moves downward to be retracted into the fixed frame 6, and the adsorption head 7 moves downward to be disengaged from the sealing plate 131. Due to the action of the connecting spring 132, the front and rear sealing plates 131 swing inward and contact each other, and the sealing plate 131 contacts the sealing frame 13, and the front and rear sealing plates 131 close the sealing frame 13, which also closes the fixed frame 6. The debris in the cutting process is also difficult to fall into the fixed frame 6. As the adsorption head 7 continues to move upward and reset, the adsorption head 7 compresses the spring 134, the adsorption head 7 moves upward and resets and disengages from the blocking block 135, and the suction end of the adsorption head 7 stops being blocked, and the adsorption head 7 continues to be sucked and fixed to the support plate. In this way, it is possible to prevent debris from falling into the fixed frame 6 during the cutting process and affecting the movement of the adsorption head 7, thereby ensuring that the adsorption head 7 can be smoothly moved into the fixed frame 6 and retracted.

[0033] See also Figures 8-10As shown, the blood collection chair support plate cutting device also includes a dust collection component installed between the electric movable plate 2 and the protective shell 3, the dust collection component includes a hollow tube 14, a suction tube 141, a blower 142, a porous tube 143, a spiral conveying plate 144, a drive motor 145 and a material blocking component, the electric movable plate 2 is fixedly connected to the top rear side of the hollow tube 14, the front side of the hollow tube 14 is connected to the rear side of the protective shell 3, the left side of the bottom of the hollow tube 14 is the discharge end, the left side of the inner side of the hollow tube 14 is fixedly connected to the porous tube 143, the porous The tube 143 can absorb the debris. The right side of the porous tube 143 is in a closed state. The left side of the porous tube 143 has no holes in the circumference and corresponds to the discharge end of the hollow tube 14. The middle part of the right side of the hollow tube 14 is rotatably connected to a spiral conveying plate 144. The inner side of the spiral conveying plate 144 contacts the outer wall of the porous tube 143. When the spiral conveying plate 144 rotates, the spiral conveying plate 144 can drive the debris to move to the left. A drive motor 145 is installed on the right side of the hollow tube 14. The output shaft end of the drive motor 145 is connected to the screw conveying plate 144. The right end of the rotary conveying plate 144 is fixedly connected, and a blower 142 is installed on the left front side of the top of the electric movable plate 2. The shaft of the blower 142 is fixedly connected to the shaft of the electric cutter 31. The air inlet end of the blower 142 is connected to the suction pipe 141, and the suction end of the suction pipe 141 is connected to the left end of the porous pipe 143. A blocking assembly is installed at the bottom of the electric movable plate 2. When the blocking assembly is in operation, the blocking assembly can block the debris ejected during the cutting process; the blocking assembly includes a corrugated cover 146 and a slide rod 147. and a buffer spring 148. Four slide rods 147 are evenly spaced and slidably connected on the front side of the bottom of the electric movable plate 2. A corrugated cover 146 is fixed between the bottom ends of the four slide rods 147. The top of the corrugated cover 146 is fixedly connected to the bottom of the electric movable plate 2. The electric cutting machine 31 is located in the corrugated cover 146. When the electric cutting machine 31 cuts the support plate, the corrugated cover 146 can block the debris ejected during the cutting process. A buffer spring 148 is connected between the lower part of the slide rod 147 and the bottom of the electric movable plate 2.

[0034] Initially, the hollow tube 14 receives the collecting container outside. When the electric cutter 31 is started, the electric cutter 31 drives the blower 142 to operate. The blower 142 operates through the suction pipe 141 to make the porous tube 143 in a negative pressure state. The porous tube 143 then suctions the protective shell 3 through the hollow tube 14, making the protective shell 3 in a negative pressure state. Subsequently, when the electric movable plate 2 drives the electric cutter 31 to move forward, the electric movable plate 2 also drives the corrugated cover 146 to move forward. The corrugated cover 146 moves forward and contacts the support plate. The support plate squeezes the corrugated cover 146, causing the corrugated cover 146 to move upward and fold. The corrugated cover 146 drives the slide bar 147 to move upward, and the buffer spring 148 is compressed, so that the electric cutter 31 presses the support plate. During cutting, the debris in the cutting process is blocked by the corrugated cover 146, and the blocked debris is sucked into the protective shell 3. The debris in the protective shell 3 is sucked into the hollow tube 14, and the debris contacts the outer wall of the porous tube 143. The porous tube 143 absorbs the debris on the outer wall, and the drive motor 145 is started. The drive motor 145 drives the spiral conveying plate 144 to rotate, and the rotation of the spiral conveying plate 144 drives the debris attached to the outer wall of the porous tube 143 to move to the left. When the debris moves to the left side of the porous tube 143, since the left side of the porous tube 143 has no holes, the debris stops being absorbed by the porous tube 143, and the debris falls down to the discharge end of the hollow tube 14, and the hollow tube 14 discharges the debris into the collection container. This is repeated, and the debris generated during the cutting process can be continuously extracted and collected. When the support plate is cut, the electric movable plate 2 drives the electric cutter 31 to move backward and reset. At the same time, the electric movable plate 2 also drives the corrugated cover 146 to move backward and reset. The corrugated cover 146 moves backward and resets, disengaging from the support plate. Due to the action of the buffer spring 148, the corrugated cover 146 moves downward and expands to reset. Then, when the electric cutter 31 is turned off, the electric cutter 31 stops driving the blower 142, and the porous tube 143 and the hollow tube 14 stop being in a negative pressure state. Then, the drive motor 145 is turned off, and the spiral conveying plate 144 stops rotating. This prevents debris from the cutting process from being ejected into the surrounding area and affecting the working environment, thereby ensuring a good working environment.

[0035] See also Figure 1 As shown, the blood collection chair support plate cutting device also includes a sensing grating 15. The sensing grating 15 is embedded and fixed on the front of the left and right guide plates 101 that are close to each other. The sensing grating 15 is electrically connected to the electric movable plate 2 through the control module.

[0036] When the support plate needs to be placed, the sensing grating 15 is started, and the sensing gratings 15 on the left and right sides emit light beams to each other to form a sensing area. When the operator is placing the support plate, the operator contacts the sensing area, and part of the light beam is blocked. The sensing grating 15 controls the electric movable plate 2 to be powered off through the control module. At this time, the electric movable plate 2 cannot be started, and the support plate can continue to be placed. After the support plate is placed, the operator leaves the sensing area, and the light beam emitted by the sensing grating 15 is not blocked. The sensing grating 15 controls the electric movable plate 2 to be powered on through the control module. When all the support plates are cut, the sensing grating 15 is turned off. In this way, during the placement of the support plate, the electric movable plate 2 can be prevented from moving and causing harm to the operator, thereby ensuring the safety of the operator in placing the support plate.
