Description

Technical Field

[0001] This invention relates to the field of plastic mold opening equipment technology, specifically to an automatic, non-destructive opening device and method for artificial crystal plastic molds. Background Technology

[0002] Plastic molds used in the production of artificial crystals typically need to have their covers opened after molding or processing. The covers of these molds fit tightly to the mold body, and when opening the cover, it is necessary to separate the cover joint while avoiding scratches, deformation, or scattering of the cover or mold body.

[0003] Manual cap opening relies on the operator's skill and force, resulting in inconsistent efficiency during continuous production and a high risk of hand contamination in the work area. While a simple conveyor system could be used for automated cap opening, the plastic cap would continue to be dragged along the conveyor belt as it runs. Under these conditions, the opening cutter or pusher would easily cause the cap to tilt, and the stress at the cap-closing joint would be uneven, affecting the opening quality. Therefore, a device is needed that can stabilize the plastic cap after it reaches the opening position before performing the opening action. Summary of the Invention

[0004] This invention provides an automatic, non-destructive cap-opening device and method for artificial crystal plastic molds, which allows the plastic cap to stop moving with the conveyor belt after reaching the opening position, and then the cap is opened by the cooperation of a cutter, a pusher plate and a limiting plate.

[0005] The technical solution of the present invention is as follows: An automatic, non-destructive cap-opening device for artificial crystal plastic molds includes a housing, a cap-opening mechanism disposed on the housing, and a transmission structure located below the cap-opening mechanism. The transmission structure includes a conveyor belt. The cap-opening mechanism includes a left mounting plate and a right mounting plate disposed opposite to each other, and the conveyor belt is located between the left mounting plate and the right mounting plate. The left mounting plate is provided with a straightening plate, a left cap-opening cylinder, and a cutter connected to the moving end of the left cap-opening cylinder. The right mounting plate is provided with a right cap-opening cylinder and a push plate connected to the moving end of the right cap-opening cylinder. A limiting plate is provided on the upper side of the push plate; a second mounting bracket is provided on one side of the left opening cylinder, and a second photoelectric switch is provided on the second mounting bracket. The detection position of the second photoelectric switch is located at the opening position between the cutter and the push plate; when the plastic cover is conveyed to the opening position by the conveyor belt, the transmission structure causes the conveyor belt to stop running, the left opening cylinder drives the cutter to move towards the closing connection of the plastic cover, the right opening cylinder drives the push plate to press against the plastic cover from the opposite side, and the limiting plate restricts the upper position of the plastic cover.

[0006] Preferably, a feeding cylinder is provided at the rear end of the left mounting plate, and a discharge rack is provided at the moving end of the feeding cylinder. A first mounting frame is provided on the right side of the feeding cylinder, and a first photoelectric switch is provided on the first mounting frame. The detection position of the first photoelectric switch is opposite to the discharge rack.

[0007] Preferably, the discharge direction of the discharge rack is towards the conveyor belt, and the eccentric plate is disposed between the discharge rack and the opening position, so that the plastic cover is guided between the cutter and the push plate when it moves with the conveyor belt.

[0008] Preferably, the cutter is positioned opposite to the push plate, and the limiting plate is located at the upper left end of the push plate; when the push plate presses against the side of the plastic cover, the limiting plate is located above the plastic cover to restrict the plastic cover from shifting upward when it is opened.

[0009] Preferably, a feeding cylinder is provided at the front end of the left mounting plate, a movable mounting plate is provided at the movable end of the feeding cylinder, a movable cylinder is provided at the front side of the movable mounting plate, and a pusher plate is provided at the movable end of the movable cylinder.

[0010] Preferably, a No. 3 mounting bracket is provided at the front end of the left side of the right mounting plate, and a No. 3 photoelectric switch is provided on the No. 3 mounting bracket. A discharge plate is provided between the front ends of the left and right mounting plates, and the detection position of the No. 3 photoelectric switch is opposite to the upper side of the discharge plate.

[0011] Preferably, the box includes a left box and a right box, with pulleys provided on the lower side of the left and right boxes, and a material box provided on the upper side of the right box. A vibrating feeding plate is provided inside the material box, and the discharge port of the vibrating feeding plate is opposite to the discharge rack. The vibrating feeding plate is used to feed plastic caps to the discharge rack.

[0012] Preferably, the transmission structure includes a motor, a drive pulley, a transmission belt, a driven pulley, a transmission shaft, a drive conveyor pulley, a conveyor belt, a driven conveyor pulley, and a driven shaft. The motor drives the transmission shaft to rotate through the drive pulley, the transmission belt, and the driven pulley, and the transmission shaft drives the conveyor belt to run through the drive conveyor pulley.

[0013] This invention also provides a method for opening a plastic mold for artificial crystals, comprising the following steps: a vibrating feeding tray sends a plastic cover to a discharge rack; after a photoelectric switch detects that there is a plastic cover in the discharge rack, a feeding cylinder drives the discharge rack to push the plastic cover to a conveyor belt; the conveyor belt moves the plastic cover forward, and a eccentric plate guides the lateral position of the plastic cover; after a photoelectric switch detects that the plastic cover has entered the opening position between the cutter and the push plate, the conveyor belt stops running; a left opening cylinder drives the cutter to move towards the closing connection of the plastic cover, a right opening cylinder drives the push plate to press against the plastic cover from the opposite side, and a limiting plate restricts the upper position of the plastic cover, so that the cutter completes the opening while the plastic cover is in the opening position.

[0014] Preferably, after the cover is opened, the conveyor belt resumes operation and transports the processed plastic cover to the discharge plate. After the photoelectric switch detects that the plastic cover has reached the discharge plate, the movable cylinder drives the pusher plate to approach the plastic cover. The feeding cylinder drives the movable mounting plate, the movable cylinder and the pusher plate to move as a whole, pushing the plastic cover out of the discharge plate.

[0015] The present invention has at least the following beneficial effects: With the above structure, the plastic cover stops moving forward with the conveyor belt when it reaches the opening position. When the cutter acts on the closing joint, it is no longer affected by the dragging of the conveyor belt. The push plate and the limiting plate can respectively restrict the side and top positions of the plastic cover, and the force of opening the cover is more concentrated.

[0016] Meanwhile, the alignment plate guides the plastic cover before opening, and the second photoelectric switch confirms its proper positioning before executing the opening action, which helps reduce scratches caused by cover misalignment. After opening, the plastic cover is conveyed out by a conveyor belt and pusher plate, reducing manual contact and making it more suitable for continuous cover opening operations of artificial crystal plastic molds.

[0019] The following combination Figures 1 to 5 This invention describes one embodiment. For ease of description, the terms front, back, left, and right used below are only used to illustrate the relative positions in the accompanying drawings and do not limit the actual placement direction of the equipment in the field.

[0020] like Figures 1 to 5 As shown, the automatic, non-destructive cap-opening equipment for artificial crystal plastic molds includes a housing 1, a cap-opening mechanism 2, and a transmission structure 3. The housing 1 includes a left housing 11 and a right housing 12. Casters 14 are installed on the lower sides of both the left and right housings 11 and 12 to facilitate movement and positioning of the equipment alongside the production line. A material box 13 is installed on the upper side of the right housing 12. A vibrating feeding tray 15 is installed inside the material box 13, and the plastic cap 4 is placed inside the vibrating feeding tray 15. The discharge port of the vibrating feeding tray 15 faces the discharge rack 214.

[0021] The opening mechanism 2 is mounted on the left mounting plate 202 and the right mounting plate 201. A feeding cylinder 203 is installed at the rear end of the left mounting plate 202, and a discharge rack 214 is installed at the moving end of the feeding cylinder 203. A first mounting frame 204 is located to the right of the feeding cylinder 203, and a first photoelectric switch 205 is mounted on the first mounting frame 204, with its detection position opposite to the discharge rack 214. After the vibrating feeding plate 15 feeds the plastic cover 4 into the discharge rack 214, the first photoelectric switch 205 detects the plastic cover 4, and the feeding cylinder 203 drives the discharge rack 214 to move, sending the plastic cover 4 onto the conveyor belt 37.

[0022] The transmission structure 3 is located below the cover opening mechanism 2. The output shaft of the motor 31 is connected to the drive pulley 32, which drives the driven pulley 34 and the transmission shaft 35 to rotate via the transmission belt 33. The transmission shaft 35 drives the drive conveyor pulley 36 to rotate, and the drive conveyor pulley 36 cooperates with the driven conveyor pulley 38 to drive the conveyor belt 37. The driven conveyor pulley 38 is mounted on the driven shaft 39. The conveyor belt 37 is located between the left mounting plate 202 and the right mounting plate 201, and is used to transport the plastic cover 4 from the loading position to the cover opening position.

[0023] A centering plate 206 is provided at the middle of the right end of the left mounting plate 202. After the plastic cover 4 enters the conveyor belt 37 from the discharge rack 214, it moves forward with the conveyor belt 37. The centering plate 206 guides the lateral position of the plastic cover 4, allowing it to enter between the cutter 208 and the push plate 213. A left opening cylinder 207 is provided in the middle of the left mounting plate 202, and the cutter 208 is connected to the moving end of the left opening cylinder 207. A right opening cylinder 212 is provided in the middle of the right mounting plate 201, and the push plate 213 is connected to the moving end of the right opening cylinder 212. A limiting plate 211 is provided at the upper left side of the push plate 213.

[0024] Mounting bracket 209 is positioned to the right of left opening cylinder 207, and photoelectric switch 210 is mounted on mounting bracket 209. The detection position of photoelectric switch 210 corresponds to the opening position between cutter 208 and push plate 213. When plastic cover 4 is conveyed to this position, the equipment first stops conveyor belt 37, causing plastic cover 4 to remain between cutter 208 and push plate 213; then, left opening cylinder 207 drives cutter 208 to move towards the closing connection of plastic cover 4, right opening cylinder 212 drives push plate 213 to press against plastic cover 4 from the opposite side, and limiting plate 211 restricts the upper position of plastic cover 4.

[0025] During the opening process described above, the plastic cover 4 no longer moves forward with the conveyor belt 37, and the cutter 208 does not need to overcome the drag from the conveyor belt 37 when it acts on the cover connection. The push plate 213 presses against the plastic cover 4 from the side, and the limiting plate 211 restricts its upper position, which can reduce the possibility of the plastic cover 4 tilting, jumping, or popping out at the moment of opening. After the cutter 208 completes the opening, the left opening cylinder 207 and the right opening cylinder 212 reset, and the conveyor belt 37 continues to run.

[0026] A feeding cylinder 215 is installed at the front end of the left mounting plate 202. A movable mounting plate 216 is installed at the movable end of the feeding cylinder 215. A movable cylinder 217 is installed in front of the movable mounting plate 216. A pusher plate 218 is installed at the movable end of the movable cylinder 217. A third mounting bracket 219 is installed at the front left side of the right mounting plate 201. A third photoelectric switch 220 is installed on the third mounting bracket 219. A discharge plate 221 is installed between the front ends of the left mounting plate 202 and the right mounting plate 201. After the plastic cover 4 is opened, it reaches the discharge plate 221 along with the conveyor belt 37. The third photoelectric switch 220 detects its arrival. The movable cylinder 217 drives the pusher plate 218 to move closer to the plastic cover 4. The feeding cylinder 215 then drives the movable mounting plate 216, the movable cylinder 217, and the pusher plate 218 to move as a whole, pushing the plastic cover 4 out of the discharge plate 221.

[0027] One opening process of the device is as follows: The vibrating feeding plate 15 feeds the plastic cover 4 into the discharge rack 214; after the photoelectric switch 205 detects that there is a plastic cover 4 in the discharge rack 214, the feeding cylinder 203 drives the discharge rack 214 to move, sending the plastic cover 4 to the conveyor belt 37. The motor 31 drives the conveyor belt 37 through the driving pulley 32, the transmission belt 33, the driven pulley 34, the transmission shaft 35, and the driving conveyor pulley 36, and the conveyor belt 37 sends the plastic cover 4 to the opening position.

[0028] When the plastic cover 4 passes the eccentric plate 206, its lateral position is corrected. After the second photoelectric switch 210 detects that the plastic cover 4 has entered between the cutter 208 and the pusher plate 213, the conveyor belt 37 stops running. The left opening cylinder 207 drives the cutter 208 to move towards the cover connection, the right opening cylinder 212 drives the pusher plate 213 to hold the plastic cover 4, and the limiting plate 211 restricts the upper position of the plastic cover 4, thus completing the opening while the plastic cover 4 is stationary in the open position.

[0029] After the lid is opened, the left lid opening cylinder 207 and the right lid opening cylinder 212 reset, and the conveyor belt 37 continues to deliver the processed plastic lid 4 to the discharge plate 221. After the photoelectric switch 220 detects that the plastic lid 4 has reached the discharge plate 221, the movable cylinder 217 drives the pusher plate 218 to contact the plastic lid 4, and the feeding cylinder 215 drives the movable mounting plate 216 and the movable cylinder 217 and pusher plate 218 on it to move, pushing the plastic lid 4 to the next process or collection position.

[0030] The sequential actions of the photoelectric switch 210, the transmission structure 3, and the cylinders can be achieved by the existing electrical control circuit of the equipment. This electrical control circuit is only used to execute the sequence of actions such as detection, belt stop, cover opening, reset, and material discharge, without changing the relative arrangement between the aforementioned mechanical components.
