Description

Technical Field

[0001] This invention relates to the field of celluloid hot pressing molding technology, specifically to a celluloid hot pressing molding apparatus and method. Background Technology

[0002] Celluloid hot pressing molding equipment typically consists of a hot press box, main support column, punch, die and drive equipment.

[0003] Patent publication number CN222223280U relates to a diaphragm hot pressing forming apparatus, including a forming body. A base plate is fixedly connected to the bottom of the forming body, and a heating mechanism and a hot pressing mechanism are fixedly connected to the top of the base plate. A rotary motor is fixedly connected inside the forming body, and a rotary shaft is fixedly connected to the drive end of the rotary motor. A four-station platform is fixedly connected to one end of the rotary shaft. A lower hot pressing mold is fixedly connected to the top of the four-station platform. A mold groove is opened on the top of the lower hot pressing mold. A control panel is fixedly connected to the outside of the four-station platform, and an installation groove is opened at the bottom of the four-station platform. A sliding ball is movably connected to the inside of the installation groove. Through the setting of the rotary motor, rotary shaft, and four-station platform, the diaphragm hot pressing forming apparatus can process gradually without processing gaps, thus improving the processing efficiency of the diaphragm hot pressing forming apparatus.

[0004] By incorporating a rotary motor, a rotary shaft, and a four-station platform, the diaphragm hot pressing molding device can process materials sequentially without any processing gaps, thus improving its processing efficiency. However, it is difficult to prevent the celluloid sheet from tilting during hot pressing. Tilt during hot pressing leads to uneven stress on the sheet, affecting molding accuracy. Therefore, it is essential to design a celluloid hot pressing molding device that is both practical and prevents tilting of the celluloid sheet during hot pressing. Summary of the Invention

[0005] The purpose of this invention is to provide a celluloid hot pressing molding apparatus and method to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a celluloid hot pressing molding device, including a hot press box and a straightening component. The hot press box has a discharge hole at its top, a main support column is provided on the inner wall of the hot press box, a punch is provided on the circumferential surface of the main support column, and a concave die is fixedly installed on the right side of the inner wall of the hot press box. The straightening component includes a main support plate, a lead screw, a slide groove, a pressure plate door, an anti-tilting plate, a protective groove, a limiting hole, a moving groove, a protective frame, a limiting plate, and an anti-tilting spring. The main support plate is fixedly installed on the top of the hot press box, and the lead screw rotates through the right side of the inner wall of the main support plate. The slide groove is located at the top of the hot press box. The pressure plate door is slidably installed on the inner wall of the slide groove. The pressure plate door is threadedly connected to the lead screw. The anti-tilt plate slides through the upper and lower walls of the pressure plate door. The protective groove is located on the left side of the anti-tilt plate. The limiting hole is located on the top of the anti-tilt plate. The moving groove is located on the top of the pressure plate door. The protective frame is slidably installed on the inner wall of the moving groove. The limiting plate is fixedly installed on the left side of the protective frame. The anti-tilt spring is located between the pressure plate door and the anti-tilt plate. The right side of the protective frame is made of rubber. The protective frame slowly deforms, causing the anti-tilt plate to slowly move upward to adjust the tilted celluloid plate.

[0007] According to the above technical solution, a rubber strip is provided between the anti-sloping plate and the pressure plate door. The rubber strip can increase the sealing between the anti-sloping plate and the pressure plate door. The limiting plate is in contact with the inner wall of the limiting hole. The limiting plate abuts against the anti-sloping plate. The protective frame moves to the left to disengage from the anti-sloping plate, thereby ensuring that the anti-sloping plate can quickly move downward to reset.

[0008] According to the above technical solution, the protective frame abuts against the protective groove, and a spring is provided between the protective frame and the moving groove. The left side of the concave mold is set in a U-shape. The anti-slant plate moves downward to reset and squeezes the anti-slant spring. The anti-slant spring is deformed and stores force under the pressure of the anti-slant plate. After the limit of the anti-slant plate is released, the anti-slant plate can be reset by the anti-slant spring. The U-shape of the left side of the concave mold facilitates the placement of the celluloid board.

[0009] According to the above technical solution, it also includes a stop component and a purification component. The stop component is used to prevent the pressure plate door from being accidentally opened during hot pressing operations. The purification component is used to purify the toxic gases generated during hot pressing operations. The stop component includes a serpentine rod, a secondary support plate, a support spring, an obstruction plate, and a stop groove. The pressure plate door is limited by the secondary support plate, preventing it from being opened arbitrarily during hot pressing operations. The secondary support plate moves upward to pull the support spring. The support spring deforms and stores force due to the pull of the secondary support plate. After the bottom of the secondary support plate is aligned with the stop groove, the support spring can drive the secondary support plate to reset. The serpentine rod slides through the top of the hot press box. The secondary support plate is fixedly installed at the top of the serpentine rod. The support spring is located between the secondary support plate and the hot press box. The obstruction plate is fixedly installed at the bottom of the serpentine rod. The stop groove is opened at the top of the pressure plate door.

[0010] According to the above technical solution, the stop assembly further includes an obstruction hole and an obstruction rod. The obstruction hole is opened on the left side of the obstruction plate, and the obstruction rod is fixedly installed on the right side of the punch. The left side of the auxiliary support plate is set as an inclined surface. The obstruction plate cannot move vertically, so the serpentine rod and the auxiliary support plate cannot move vertically during the hot pressing operation.

[0011] According to the above technical solution, the purification component includes a purification device, a power plug, a secondary support column, and a power socket. The power socket moves downward to connect with the power plug and power the purification device. The purification device is fixedly installed on the front side of the concave mold, the power plug is fixedly installed on the top of the purification device, the secondary support column is fixed on the top of the purification device, and the power socket is slidably installed on the circumferential surface of the secondary support column.

[0012] According to the above technical solution, the purification component also includes a reset spring and a curved panel. The reset spring is disposed between the power socket and the purification equipment. When the power socket moves downward, it compresses the reset spring. The reset spring deforms and stores force under the compression of the power socket. After the power socket is released from contact with the obstruction rod, the reset spring can drive the power socket to return to its initial position. The curved panel is fixedly installed on the top of the purification equipment.

[0013] According to the above technical solution, the curved panel is elastic, the top of the power socket is set as an inclined surface, the power socket is used to supply power to the purification equipment, and the curved panel recovers under its own elasticity and helps the power socket to disengage from the power plug.

[0014] A method of using a celluloid hot pressing molding apparatus, comprising the following steps:

[0015] Step 1: Place the celluloid sheet to be hot-pressed on the left side of the die. Start the servo motor to drive the lead screw to rotate. The rotation of the lead screw drives the pressure plate door to move to the right. The movement of the pressure plate door to the right drives the anti-skewing plate to move. The anti-skewing plate moves to the right and contacts the celluloid sheet to be hot-pressed, and squeezes the celluloid sheet.

[0016] Step 2: After the pressure plate door moves to the right and seals the discharge hole, manually push the protective frame to the left. The movement of the protective frame to the left will cause the limiting plate to move, and the limiting plate will move away from the anti-sloping plate and release the limiting effect on the anti-sloping plate.

[0017] Step 3: After the anti-tilt plate is released from its limit, the anti-tilt plate moves upward under the elastic force of the anti-tilt spring. As the anti-tilt plate moves upward, it squeezes the celluloid plate to ensure that the celluloid plate will not tilt during the hot pressing operation.

[0018] Step 4: After the tilted celluloid plate is adjusted, the drive equipment moves the punch closer to the celluloid plate. The punch moves closer to the celluloid plate and contacts the die to close the mold and perform hot pressing to heat press the celluloid plate into a ring shape.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] (1) In this invention, the protective frame slowly deforms to make the anti-slant plate slowly move upward to adjust the tilted celluloid plate. Slight tilting of the celluloid plate will cause dimensional deviation after hot pressing. The slow deformation of the protective frame can make the anti-slant plate adjust the celluloid plate in a gradual manner, thereby making the edge of the celluloid plate evenly pressed and preventing excessive friction between the anti-slant plate and the celluloid plate from causing the celluloid plate to shift position, thereby improving the forming accuracy of the celluloid plate. By moving the protective frame to the left to disengage from the anti-slant plate, it is ensured that the anti-slant plate can quickly move downward to reset. The anti-slant plate can quickly move downward to reset, thereby accelerating the hot pressing production efficiency of the celluloid plate.

[0021] (2) In this invention, the pressure plate door is limited by the auxiliary support plate so that the pressure plate door cannot be opened at will during the hot pressing operation. During the celluloid hot pressing process, the auxiliary support plate prevents the pressure plate door from being opened by mistake, which can avoid burns to the operator caused by the high temperature of the board.

[0022] (3) This invention prevents the serpentine rod and the auxiliary support plate from moving vertically during the hot pressing process by preventing the obstruction plate from moving vertically. By limiting the auxiliary support plate twice, multiple safety protections are formed, which can further prevent camphor vapor leakage caused by the opening of the pressure plate door, thereby preventing toxic gas leakage and achieving green production.

[0023] (4) In this invention, the power socket is moved upward to reset and disconnect from the power plug and the power is cut off to the purification equipment. The forced ventilation of the purification fan will change the flow direction of the hot air around the punch and die, resulting in local temperature fluctuations. By cutting off the power to the purification equipment, the change in the flow direction of the hot air is avoided, thereby ensuring the uniformity of the preheating of the punch and die.

[0024] (5) The invention restores itself under the action of its own elasticity and assists the power socket to disengage from the power plug. After repeated plugging and unplugging, the power socket and power plug are prone to problems such as jamming. The assisted disengagement by the curved panel can prevent the power socket and power plug from being plugged too tightly, which would prevent the purification equipment from being unable to shut off the power and ensure the continuous and stable operation of the hot pressing production process.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1-8 The present invention provides a technical solution: a celluloid hot pressing molding device, including a hot press box 1 and a straightening component. The hot press box 1 has a discharge hole 101 at the top, a main support column 2 is provided on the inner wall of the hot press box 1, a punch 3 is provided on the circumferential surface of the main support column 2, and a die 4 is fixedly installed on the right side of the inner wall of the hot press box 1; the straightening component includes a main support plate 5, a lead screw 6, a slide groove 7, a pressure plate door 8, an anti-tilting plate 9, a protective groove 901, a limiting hole 10, a moving groove 11, a protective frame 12, a limiting plate 13, and an anti-tilting spring 14. The main support plate 5 is fixedly installed on the top of the hot press box 1, the lead screw 6 rotates through the right side of the inner wall of the main support plate 5, the slide groove 7 is opened on the top of the hot press box 1, and the pressure plate door 8 is slidably installed on the inner wall of the slide groove 7. 8 is threadedly connected to the lead screw 6. The anti-slant plate 9 slides through the upper and lower walls of the pressure plate door 8. The protective groove 901 is opened on the left side of the anti-slant plate 9. The limiting hole 10 is opened on the top of the anti-slant plate 9. The moving groove 11 is opened on the top of the pressure plate door 8. The protective frame 12 is slidably installed on the inner wall of the moving groove 11. The limiting plate 13 is fixedly installed on the left side of the protective frame 12. The anti-slant spring 14 is set between the pressure plate door 8 and the anti-slant plate 9. The right side of the protective frame 12 is made of rubber. The slow deformation of the protective frame 12 can allow the anti-slant plate 9 to adjust the celluloid plate in a gradual manner, so that the edge of the celluloid plate is evenly pressed and the excessive friction between the anti-slant plate 9 and the celluloid plate can prevent the celluloid plate from shifting position due to excessive friction, thereby improving the forming accuracy of the celluloid plate.

[0037] A rubber strip is provided between the anti-sloping plate 9 and the pressure plate door 8. The rubber strip can increase the sealing between the anti-sloping plate 9 and the pressure plate door 8. The limiting plate 13 contacts the inner wall of the limiting hole 10 and abuts against the anti-sloping plate 9. The protective frame 12 moves to the left to disengage from the anti-sloping plate 9, thereby ensuring that the anti-sloping plate 9 can move downward and reset quickly. The anti-sloping plate 9 can move downward and reset quickly, thereby accelerating the hot pressing production efficiency of the celluloid plate.

[0038] The protective frame 12 abuts against the protective groove 901. A spring is provided between the protective frame 12 and the moving groove 11. The left side of the concave mold 4 is set in a U-shape. The anti-slant plate 9 moves downward to reset and squeezes the anti-slant spring 14. The anti-slant spring 14 is deformed and stores force under the pressure of the anti-slant plate 9. After the limit of the anti-slant plate 9 is released, the anti-slant spring 14 can drive the anti-slant plate 9 to reset. The U-shape of the left side of the concave mold 4 makes it convenient to place the celluloid board.

[0039] A method of using a celluloid hot pressing molding apparatus, comprising the following steps:

[0040] Step 1: Place the celluloid sheet to be hot-pressed on the left side of the die 4, start the servo motor to drive the lead screw 6 to rotate, the lead screw 6 rotates to drive the pressure plate door 8 to move to the right, the pressure plate door 8 moves to the right to drive the anti-skewing plate 9 to move, the anti-skewing plate 9 moves to the right to contact the celluloid sheet to be hot-pressed and squeeze the celluloid sheet.

[0041] Step 2: After the pressure plate door 8 moves to the right and seals the discharge hole 101, manually push the protective frame 12 to the left. The movement of the protective frame 12 to the left will cause the limiting plate 13 to move. The limiting plate 13 will move away from the anti-sloping plate 9 and release the limiting effect on the anti-sloping plate 9.

[0042] Step 3: After the limit of the anti-tilt plate 9 is released, the anti-tilt plate 9 moves upward under the elastic force of the anti-tilt spring 14. As the anti-tilt plate 9 moves upward, it squeezes the celluloid plate to ensure that the celluloid plate will not tilt during the hot pressing operation.

[0043] Step 4: After the tilted celluloid plate is adjusted, the drive equipment moves the punch 3 towards the celluloid plate. The punch 3 moves towards the celluloid plate and contacts the die 4 to close the mold and perform hot pressing to heat press the celluloid plate into a ring shape.

[0044] During operation, the celluloid sheet to be hot-pressed is placed on the left side of the die 4. After the celluloid sheet is placed securely, a servo motor is installed on the right side of the main support plate 5, and the output end of the servo motor is fixedly connected to the lead screw 6. The servo motor is started to drive the lead screw 6 to rotate. The rotation of the lead screw 6 causes the pressure plate door 8 to move to the right. The movement of the pressure plate door 8 to the right causes the anti-skewing plate 9 to move. The anti-skewing plate 9 moves to the right and contacts the celluloid sheet to be hot-pressed, pressing the celluloid sheet. At the same time, the movement of the pressure plate door 8 to the right blocks and seals the discharge hole 101. After the pressure plate door 8 moves to the right and seals the discharge hole 101, Manually push the protective frame 12 to the left. This movement compresses the spring 1, causing it to deform and store force. Simultaneously, the leftward movement of the protective frame 12 moves the limiting plate 13, disengaging it from the anti-tilt plate 9 and releasing it from its limiting position. Once the anti-tilt plate 9 is released, it moves upward under the elastic force of the anti-tilt spring 14. This upward movement compresses the celluloid sheet, ensuring it does not tilt during hot pressing. Release the spring when the anti-tilt plate 9 has moved upward. The limiting plate 13 moves to the right and resets under the elastic force of the spring 1. The rightward movement of the limiting plate 13 causes the protective frame 12 to move to the right. The protective frame 12 moves to the right and contacts the protective groove 901. When the anti-tilt plate 9 moves upward, it will squeeze the protective frame 12. The protective frame 12 slowly deforms under the pressure of the limiting plate 13. The slow deformation of the protective frame 12 causes the anti-tilt plate 9 to slowly move upward to adjust the tilted celluloid plate. After the tilted celluloid plate is adjusted, the hot press box 1 is equipped with a driving device, and the output end of the driving device is connected to the punch 3. The fixed, driven equipment operation drives the punch 3 to move closer to the celluloid plate. The punch 3 moves closer to the celluloid plate and contacts the die 4 to close the mold and perform hot pressing. After the hot pressing is completed, the protective frame 12 is manually pushed to the left. The protective frame 12 moves to the left and drives the limit plate 13 to move. The limit plate 13 moves to the left and aligns with the limit hole 10. After the limit plate 13 is aligned with the limit hole 10, the anti-slant plate 9 is pressed down to move and reset. At the same time, the protective frame 12 moves to the left to disengage from the anti-slant plate 9, thereby ensuring that the anti-slant plate 9 can move down and reset quickly.

[0045] Example 2: Please refer to Figures 1-8Based on Embodiment 1, this embodiment further includes a stop assembly and a purification assembly. The stop assembly prevents the pressure plate door 8 from being accidentally opened during hot pressing. The purification assembly purifies the toxic gases generated during hot pressing. The stop assembly includes a serpentine rod 151, a secondary support plate 152, a support spring 153, an obstruction plate 154, and a stop groove 157. The secondary support plate 152 moves upward to pull the support spring 153. The support spring 153 deforms and stores force under the pull of the secondary support plate 152. After the bottom of plate 152 is aligned with the stop groove 157, the auxiliary support plate 152 can be reset by the support spring 153. The serpentine rod 151 slides through the top of the hot press box 1. The auxiliary support plate 152 is fixedly installed on the top of the serpentine rod 151. The support spring 153 is set between the auxiliary support plate 152 and the hot press box 1. The obstruction plate 154 is fixedly installed at the bottom of the serpentine rod 151. The stop groove 157 is opened at the top of the pressure plate door 8. The auxiliary support plate 152 prevents the pressure plate door from being opened accidentally, which can avoid burns to the operator caused by the high temperature of the plate.

[0046] The stop assembly also includes an obstruction hole 155 and an obstruction rod 156. The obstruction hole 155 is opened on the left side of the obstruction plate 154, and the obstruction rod 156 is fixedly installed on the right side of the punch 3. The left side of the auxiliary support plate 152 is set as an inclined surface. The obstruction plate 154 cannot move vertically, so the serpentine rod 151 and the auxiliary support plate 152 cannot move vertically during the hot pressing operation. By limiting the auxiliary support plate 152, multiple safety protections are formed, which can further prevent camphor vapor leakage caused by the opening of the pressure plate door 8, thereby preventing toxic gas leakage and realizing green production.

[0047] The purification assembly includes a purification device 161, a power plug 162, a secondary support column 163, and a power socket 164. The purification device 161 is fixedly installed on the front side of the die 4, the power plug 162 is fixedly installed on the top of the purification device 161, the secondary support column 163 is fixed on the top of the purification device 161, and the power socket 164 is slidably installed on the circumferential surface of the secondary support column 163. By disconnecting the power to the purification device 161, the change in the direction of hot air flow is avoided, thereby ensuring the uniformity of preheating of the punch 3 and the die 4.

[0048] The purification assembly also includes a return spring 165 and a curved panel 166. The return spring 165 is disposed between the power socket 164 and the purification device 161. When the power socket 164 moves downward, it presses the return spring 165. The return spring 165 deforms and stores force under the pressure of the power socket 164. After the power socket 164 disengages from the obstruction rod 156, the return spring 165 can drive the power socket 164 to return to its initial position. The curved panel 166 is fixedly installed on the top of the purification device 161.

[0049] The curved panel 166 is elastic, and the top of the power socket 164 is set as an angle. The power socket 164 is used to supply power to the purification equipment 161. The curved panel 166 recovers under its own elasticity and assists the power socket 164 to disengage from the power plug 162. The assisted disengagement by the curved panel 166 can prevent the power socket 164 from being too tightly connected to the power plug 162, which would prevent the purification equipment 161 from being unable to shut off the power, thus ensuring the continuous and stable operation of the hot pressing production process.

[0050] During operation, the pressure plate door 8 moves to the right and contacts the inclined surface of the auxiliary support plate 152, pressing against it. The auxiliary support plate 152 moves upward under the pressure of the pressure plate door 8. As the pressure plate door 8 continues to move to the right, blocking and sealing the discharge hole 101, it continues to move to the right until the bottom of the auxiliary support plate 152 aligns with the stop groove 157. After the bottom of the auxiliary support plate 152 aligns with the stop groove 157, the auxiliary support plate 152 moves downward under the elastic force of the support spring 153, resetting its position. The auxiliary support plate 152 moves downward and contacts the inner wall of the stop groove 157, limiting the pressure plate door 8. The pressure plate door 8 is then subjected to the pressure of the auxiliary support... The limiting position of the support plate 152 prevents the pressure plate door 8 from being opened arbitrarily during hot pressing. After the pressure plate door 8 blocks and seals the discharge hole 101, the drive equipment moves the punch 3 towards the celluloid plate. The movement of the punch 3 towards the celluloid plate moves the obstruction rod 156. The obstruction rod 156 moves to the right and contacts the inner wall of the obstruction hole 155, limiting the obstruction plate 154. The obstruction plate 154 is limited by the obstruction rod 156 and cannot move vertically. The inability of the obstruction plate 154 to move vertically prevents the serpentine rod 151 and the auxiliary support plate 152 from moving vertically during hot pressing.

[0051] The obstruction rod 156 moves to the right and contacts the inclined surface of the power socket 164, pressing it against the power socket 164. The power socket 164 moves downward under the pressure of the obstruction rod 156, connecting with the power plug 162 and energizing the purification equipment 161. After being energized, the purification equipment 161 operates at full power to purify the toxic gases generated during the hot pressing operation. Simultaneously, the power socket 164 moves downward, pressing the curved panel 166. The curved panel 166 deforms and accumulates force under the pressure of the power socket 164. After the hot pressing operation is completed, the drive equipment moves the punch 3 to the left to reset. The leftward movement of the punch 3 causes the obstruction rod 156 to move downward. 6. Movement: The obstruction rod 156 moves to the left to disengage from the power socket 164. After the power socket 164 disengages from the obstruction rod 156, it moves upward under the elastic force of the return spring 165 to reset. The power socket 164 moves upward to reset and disengage from the power plug 162, thus disconnecting the power to the purification equipment 161. This ensures that the purification equipment 161 only performs purification operations during hot pressing. At the same time, the curved panel 166 returns to its original position under its own elastic force and assists the power socket 164 in disengaging from the power plug 162, thereby preventing the power socket 164 from being too tightly connected to the power plug 162, which would prevent the purification equipment 161 from being unable to disconnect from the power.
