Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic bottle production technology, specifically to a clamp-and-push type bottle bottom sprue removal device. Background Technology
[0002] In the production of injection-molded products such as plastic bottles, the removal of sprue material at the bottom of the bottle is one of the key steps affecting production efficiency and product quality. Sprue material is excess material that connects the bottle body to the gating system during injection molding, and it needs to be precisely removed after molding to ensure the integrity of the bottle's appearance and its performance.
[0003] Traditional methods of removing sprue mainly rely on manual operation. However, there are often certain technical problems in the process of manually removing sprue. For example, manually cutting or breaking the sprue is labor-intensive and inefficient. Moreover, the operation accuracy is affected by the worker's experience, which can easily lead to sprue residue or damage to the bottom of the bottle, thus affecting the product qualification rate. Utility Model Content
[0004] This invention addresses the shortcomings of existing technologies by providing a clamping and pushing device for removing sprue material from the bottom of plastic bottles, which facilitates the removal of sprue material from the bottom of plastic bottles by workers.
[0005] This utility model is achieved through the following technical solution: a clamping and pushing type bottle bottom sprue material removal device is provided, including a clamping and feeding mechanism and a sprue material removal mechanism. The sprue material removal mechanism includes a first frame and two support plates fixedly connected to the top of the first frame. Two top plates are provided between the two support plates. A cylinder is fixedly installed on the outer wall of one of the support plates. The piston rod of the cylinder passes through one of the support plates and is fixedly connected to the outer wall of one of the top plates. A limit rod is provided on the outer wall of the other support plate. The limit rod passes through the other support plate and is fixedly connected to the outer wall of the other top plate. A spring is sleeved on the limit rod and fixedly connected to the other support plate and the other top plate respectively.
[0006] In use, this invention employs a clamping and feeding mechanism and a sprue removal mechanism. The sprue removal mechanism includes a first frame and two support plates fixed to the top of the first frame. Two top plates are positioned between the two support plates. A cylinder is fixedly mounted on the outer wall of one support plate, with the piston rod passing through one support plate and fixed to the outer wall of one top plate. A limit rod is mounted on the outer wall of the other support plate, passing through the other support plate and fixed to the outer wall of the other top plate. Springs are fitted on the limit rod and fixed to both the other support plate and the other top plate. During use, the clamping and feeding mechanism clamps and fixes the plastic bottle, controlling its movement to allow the sprue from the bottom of the clamped bottle to enter between the two top plates. Then, the cylinder is opened, extending its piston rod, which moves within one of the support plates, pushing the top plate fixed to the piston rod towards the sprue at the bottom of the plastic bottle. The material moves in the direction of the cylinder and comes into contact with the sprue material at the bottom of the plastic bottle. Under the push of one top plate, the sprue material at the bottom of the plastic bottle comes into contact with another top plate, which in turn pushes the other top plate to move away from the cylinder. This causes the limiting rod to move away from the cylinder along with the other top plate in another support plate, compressing the spring. This causes the sprue material at the bottom of the plastic bottle to detach from the bottom of the plastic bottle under the clamping drive of one top plate and the other top plate, making it convenient for workers to remove the sprue material from the bottom of the plastic bottle. Then, by controlling the piston rod of the cylinder to retract, one of the top plates fixed to the piston rod of the cylinder returns to its initial position, and the other top plate also returns to its initial position under the drive of the spring. Then, the top of the plastic bottle is fixed by the clamp, and the clamping and feeding mechanism is controlled to stop clamping and fix the plastic bottle and return to its initial position. Then, the plastic bottle is transported to the next process by the clamp. This makes it convenient for workers to remove the sprue material from the bottom of the plastic bottle.
[0007] Preferably, the clamping and feeding mechanism includes a second frame and two slide grooves on the top of the second frame. Slide plates are installed in the slide grooves, extending vertically. Moving wheels are fixedly installed on the bottom of the slide plates. A gear is installed between the two slide plates, and two racks are meshed on the gear. The two racks are located on the upper and lower sides of the gear, respectively, extending laterally away from the gear and passing through the two slide plates. A horizontal plate is fixedly connected to the end of each rack away from the gear. A connecting rod extending laterally towards the gear and passing through the slide plate is fixedly connected to the side wall of the horizontal plate facing the slide plate. A clamping element is fixedly connected to the end of the connecting rod away from the horizontal plate. Baffles are respectively provided on the front and rear side walls of the racks, located between the two slide plates. The front and rear baffles abut against the front and rear side walls of the gear. A threaded rod is provided in the inner hole of the gear, threadedly connected to the inner wall of the gear. The threaded rod is located between the upper and lower baffles. A rotating motor fixedly installed on the top of the second frame is fixedly connected to one end of the threaded rod.The clamping and feeding mechanism includes a second frame and two slots on the top of the second frame. Slides are installed in the slots, extending vertically. Casters are fixedly mounted on the bottom of the slides. A gear is positioned between the two slides, with two racks meshing on the gear. The racks are located on the upper and lower sides of the gear, respectively, extending laterally away from the gear and passing through the two slides. A horizontal plate is fixedly connected to the end of the racks away from the gear. A connecting rod extending laterally towards the gear and passing through the slide is fixedly connected to the side wall of the horizontal plate facing the slide. A clamping element is fixedly connected to the end of the connecting rod away from the horizontal plate. Baffles are respectively installed on the front and rear side walls of the racks, located between the two slides. The front and rear baffles respectively interact with the front and rear side walls of the gear. The gear has a threaded rod inside its inner hole that is threaded to the inner wall of the gear. The threaded rod is located between the upper and lower baffles. A rotating motor is fixedly installed on the top of the second frame and is fixed to one end of the threaded rod. When the device is in use, the rotating motor is turned on to rotate in the forward direction, which drives the threaded rod to rotate in the forward direction as well. This causes the gear to rotate with the threaded rod, so that the upper and lower racks move towards each other in the slide plate under the transmission of the gear. This causes the horizontal plate to move towards the gear along with the racks, and drives the connecting rod to move towards the gear in the slide plate as well. This causes the clamping part to move with the connecting rod and come into contact with the plastic bottle, thereby clamping and fixing the plastic bottle. After clamping and fixing the plastic bottle, the clamping components can no longer move under the drive of the connecting rod. The gear and rack remain relatively fixed. At this time, the rotating motor continues to drive the threaded rod to rotate forward. Driven by the rotation of the threaded rod, the gear moves on the threaded rod and, through the transmission of the baffle and rack, the slide plate moves in the slide groove with the support of the moving wheels. This causes the clamped plastic bottle to move as well, allowing the sprue material at the bottom of the clamped plastic bottle to enter between the two top plates. After the sprue material is removed from the bottom of the plastic bottle, the rotating motor is controlled to rotate in the opposite direction, causing the gear to rotate with the threaded rod, thus causing the upper and lower racks to move in the transmission of the gear. The components move in opposite directions within the slide, causing the horizontal plate to move away from the gear along with the rack. This, in turn, moves the connecting rod away from the gear within the slide, causing the clamping component to move with the connecting rod and no longer contact the plastic bottle, thus ceasing to clamp and fix the bottle. When the baffle abuts against the inner wall of the slide, the clamping component can no longer move under the drive of the connecting rod, and the gear and rack remain relatively fixed. At this time, the rotating motor continues to drive the threaded rod to rotate in the opposite direction. Driven by the rotation of the threaded rod, the gear moves on the threaded rod, and through the transmission of the baffle and rack, the slide moves within the groove with the support of the moving wheels and returns to its initial position.
[0008] Preferably, the clamping member includes a vertical plate fixedly connected to the end of the connecting rod away from the horizontal plate. The inner side wall of the vertical plate is provided with a first clamping plate and a second clamping plate distributed vertically. The inner side wall of the first clamping plate is provided with a first arc-shaped groove adapted to the mouth of the plastic bottle, and the inner side wall of the second clamping plate is provided with a second arc-shaped groove adapted to the body of the plastic bottle. The clamping device includes a vertical plate fixed to the end of the connecting rod away from the horizontal plate. The inner side wall of the vertical plate is provided with a first clamping plate and a second clamping plate distributed vertically. The inner side wall of the first clamping plate is provided with a first arc-shaped groove adapted to the mouth of the plastic bottle, and the inner side wall of the second clamping plate is provided with a second arc-shaped groove adapted to the body of the plastic bottle. When the device is in use, the vertical plate moves with the connecting rod, which drives the first clamping plate and the second clamping plate to move as well. This causes the first arc-shaped groove and the second arc-shaped groove to move with the first clamping plate and the second clamping plate, and respectively contact or detach from the mouth and body of the plastic bottle, thereby clamping or separating the plastic bottle.
[0009] Preferably, a discharge port is provided at the top of the first frame, and the discharge port is located between the two support plates. By providing a discharge port at the top of the first frame and placing it between the two support plates, the discharge port facilitates the falling of sprue material from the top of the first frame, preventing it from accumulating at the top of the first frame.
[0010] Preferably, rubber pads are fixedly connected to the inner arc surfaces of the first and second arc grooves. By fixing rubber pads to the inner arc surfaces of the first and second arc grooves, the stability of the device during use can be improved, and damage to the surface of the plastic bottle can be avoided by the first and second clamping plates during use.
[0011] The beneficial effects of this utility model are as follows: By setting a clamping and feeding mechanism and a sprue removal mechanism, the sprue removal mechanism includes a first frame and two support plates fixedly connected to the top of the first frame. Two top plates are provided between the two support plates. A cylinder is fixedly installed on the outer wall of one support plate. The piston rod of the cylinder passes through one support plate and is fixedly connected to the outer wall of one top plate. A limit rod is provided on the outer wall of the other support plate. The limit rod passes through the other support plate and is fixedly connected to the outer wall of the other top plate. A spring is sleeved on the limit rod and fixedly connected to the other support plate and the other top plate respectively. When the device is in use, the clamping and feeding mechanism clamps and fixes the plastic bottle and controls its movement, so that the sprue at the bottom of the clamped and fixed plastic bottle enters between the two top plates. Then, the cylinder is opened by controlling it, so that the piston rod of the cylinder extends, thereby moving the piston rod of the cylinder within one support plate, thereby pushing one of the top plates fixed to the piston rod of the cylinder toward the sprue at the bottom of the plastic bottle. The material moves in the direction of the cylinder and comes into contact with the sprue material at the bottom of the plastic bottle. Under the push of one top plate, the sprue material at the bottom of the plastic bottle comes into contact with another top plate, which in turn pushes the other top plate to move away from the cylinder. This causes the limiting rod to move away from the cylinder along with the other top plate in another support plate, compressing the spring. This causes the sprue material at the bottom of the plastic bottle to detach from the bottom of the plastic bottle under the clamping drive of one top plate and the other top plate, making it convenient for workers to remove the sprue material from the bottom of the plastic bottle. Then, by controlling the piston rod of the cylinder to retract, one of the top plates fixed to the piston rod of the cylinder returns to its initial position, and the other top plate also returns to its initial position under the drive of the spring. Then, the top of the plastic bottle is fixed by the clamp, and the clamping and feeding mechanism is controlled to stop clamping and fix the plastic bottle and return to its initial position. Then, the plastic bottle is transported to the next process by the clamp. This makes it convenient for workers to remove the sprue material from the bottom of the plastic bottle.

[0019] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0020] like Figures 1-5 The present invention discloses a clamping and pushing type bottle bottom sprue removal device, which includes a clamping and feeding mechanism and a sprue removal mechanism. The sprue removal mechanism includes a first frame 5 and two support plates 11 fixedly connected to the top of the first frame 5. Two top plates 9 are arranged between the two support plates 11. A cylinder 12 is fixedly installed on the outer wall of one of the support plates 11. The piston rod of the cylinder 12 passes through one of the support plates 11 and is fixedly connected to the outer wall of one of the top plates 9. A limiting rod 4 is provided on the outer wall of the other support plate 11. The limiting rod 4 passes through the other support plate 11 and is fixedly connected to the outer wall of the other top plate 9. A spring 14 is sleeved on the limiting rod 4 and fixedly connected to the other support plate 11 and the other top plate 9 respectively.
[0021] The clamping and feeding mechanism includes a second frame 6 and two slide grooves 22 formed on the top of the second frame 6. Slide plates 1 are installed in the slide grooves 22, extending vertically. Moving wheels 20 are fixedly installed at the bottom of the slide plates 1. A gear 17 is installed between the two slide plates 1, and two racks 18 are meshed on the gear 17. The two racks 18 are located on the upper and lower sides of the gear 17, respectively. Both racks 18 extend laterally away from the gear 17 and pass through the two slide plates 1. A horizontal plate 3 is fixedly connected to the end of the rack 18 away from the gear 17. A connecting rod 2 extending laterally towards the gear 17 and passing through the slide plate 1 is fixedly connected to the side wall of the horizontal plate 3 facing the slide plate 1. A clamping element is fixedly connected to the end of the connecting rod 2 away from the horizontal plate 3. Clamping elements are respectively provided on the front and rear side walls of the rack 18. A baffle 19 is located between the two slide plates 1. The front and rear baffles 19 abut against the front and rear side walls of the gear 17, respectively. A threaded rod 21 is provided in the inner hole of the gear 17 and is threaded to the inner wall of the gear 17. The threaded rod 21 is located between the upper and lower baffles 19. A rotary motor 15 is fixedly installed on the top of the second frame 6 and is fixed to one end of the threaded rod 21. When the device is in use, the rotary motor 15 is turned on to rotate in the forward direction, so that the rotary motor 15 drives the threaded rod 21 to rotate in the forward direction as well. This causes the gear 17 to rotate with the threaded rod 21, so that the upper and lower racks 18 move towards each other in the slide plate 1 under the transmission of the gear 17. This causes the horizontal plate 3 to move towards the gear 17 along with the racks 18, and drives the connecting rod 2 to move in the same direction. The slide plate 1 also moves towards the gear 17, causing the clamping component to move along with the connecting rod 2 and contact the plastic bottle, thus clamping and fixing the plastic bottle. After the clamping component contacts and fixes the plastic bottle, it can no longer move under the drive of the connecting rod 2. The gear 17 and rack 18 remain relatively fixed. At this time, the rotating motor 15 continues to drive the threaded rod 21 to rotate in the forward direction. The gear 17 moves on the threaded rod 21 under the rotation drive of the threaded rod 21, and through the transmission of the baffle 19 and rack 18, the slide plate 1 moves in the slide groove 22 under the support of the moving wheel 20, thereby moving the clamped and fixed plastic bottle, thus causing the bottom of the clamped and fixed plastic bottle to move. The sprue material enters between the two top plates 9. After the sprue material is removed from the bottom of the plastic bottle, the rotating motor 15 is controlled to rotate in the opposite direction, causing the gear 17 to rotate with the threaded rod 21. This causes the upper and lower racks 18 to move towards each other within the slide plate 1 under the drive of the gear 17. This causes the horizontal plate 3 to move away from the gear 17 along with the racks 18, and also drives the connecting rod 2 to move away from the gear 17 within the slide plate 1. This causes the clamping member to move with the connecting rod 2 and no longer abut against the plastic bottle, thus ceasing to clamp and fix the plastic bottle. When the baffle 19 abuts against the inner wall of the slide plate 1, the clamping member can no longer move under the drive of the connecting rod 2, and the gear 17 and rack 18 remain relatively fixed.At this time, the rotating motor 15 continues to drive the threaded rod 21 to rotate in the opposite direction. The gear 17 will move on the threaded rod 21 under the rotation drive of the threaded rod 21, and through the transmission of the baffle 19 and the rack 18, the slide plate 1 will move in the slide groove 22 under the support of the moving wheel 20 and return to the initial position. The clamping device includes a vertical plate 7 fixedly connected to the end of the connecting rod 2 away from the horizontal plate 3. The inner side wall of the vertical plate 7 is provided with a first clamping plate 8 and a second clamping plate 10 distributed vertically. The inner side wall of the first clamping plate 8 is provided with a first arc-shaped groove 23 adapted to the mouth of the plastic bottle, and the inner side wall of the second clamping plate 10 is provided with a second arc-shaped groove 16 adapted to the body of the plastic bottle. When the device is in use, the vertical plate 7 moves with the connecting rod 2, and drives the first clamping plate 8 and the second clamping plate 10 to move, so that the first arc-shaped groove 23 and the second arc-shaped groove 16 also move with the first clamping plate 8 and the second clamping plate 10, and respectively contact or detach from the mouth and body of the plastic bottle, thereby clamping or separating the plastic bottle. A discharge port 24 is provided at the top of the first frame 5, located between the two support plates 11. This discharge port 24 facilitates the removal of sprue material from the top of the first frame 5, preventing accumulation. Rubber pads 13 are fixed to the inner arc surfaces of the first arc-shaped groove 23 and the second arc-shaped groove 16. These rubber pads improve the stability of the device during use, preventing damage to the plastic bottle surface from the first clamping plate 8 and the second clamping plate 10. The top plate 9 is L-shaped, with its long side extending vertically downwards and its short side extending laterally inwards. This facilitates the removal of sprue material from the bottom of the plastic bottle.
[0022] Combined with appendix Figure 1-5The method of using this utility model is as follows: First, by controlling the rotation motor 15 to start rotating in the forward direction, the rotation motor 15 drives the threaded rod 21 to rotate in the forward direction as well. This causes the gear 17 to rotate with the threaded rod 21, thereby causing the upper and lower racks 18 to move towards each other in the slide plate 1 under the transmission of the gear 17. This causes the horizontal plate 3 to move towards the gear 17 along with the racks 18, and also causes the connecting rod 2 to move towards the gear 17 in the slide plate 1. This causes the vertical plate 7 to move with the connecting rod 2, and also causes the first clamping plate 8 and the second clamping plate 10 to move. This causes the first arc groove 23 and the second arc groove 16 to move along with the first clamping plate 8 and the second clamping plate 10, and also causes the rubber pad 13 to move. As the first arc-shaped groove 23 and the second arc-shaped groove 16 move, they respectively contact the bottle mouth and the bottle body of the plastic bottle to clamp the plastic bottle. After the clamping member contacts and clamps the plastic bottle, it can no longer move under the drive of the connecting rod 2. The gear 17 and the rack 18 remain relatively fixed. At this time, the rotating motor 15 continues to drive the threaded rod 21 to rotate in the forward direction. The gear 17 will move on the threaded rod 21 under the rotation drive of the threaded rod 21, and through the transmission of the baffle 19 and the rack 18, the slide plate 1 moves in the slide groove 22 under the support of the moving wheel 20, thereby moving the clamped plastic bottle as well, so that the sprue material at the bottom of the clamped plastic bottle is removed. The material enters between the two top plates 9, and then the cylinder 12 is opened, causing the piston rod of the cylinder 12 to extend. This causes the piston rod to move within one of the support plates 11, pushing one of the top plates 9, which is fixed to the piston rod of the cylinder 12, towards the bottom sprue material of the plastic bottle, and into contact with it. The bottom sprue material, pushed by one top plate 9, then contacts the other top plate 9, pushing the other top plate 9 away from the cylinder 12. This causes the limiting rod 4 to move away from the cylinder 12 along with the other top plate 9 within the other support plate 11, compressing the spring 14. Thus, the bottom sprue material of the plastic bottle, driven by the clamping action of the two top plates 9, is pressed against the plastic... The bottom of the plastic bottle detaches, thus removing the sprue material from the bottom of the plastic bottle. The sprue material removed from the bottom of the plastic bottle falls from the top of the first frame 5 through the discharge port 24, preventing it from accumulating on the top of the first frame 5. Then, by controlling the piston rod of the cylinder 12 to retract, one of the top plates 9 fixed to the piston rod of the cylinder 12 returns to its initial position, and the other top plate 9 also returns to its initial position under the drive of the spring 14. Then, the top of the plastic bottle is fixed by a clamp, and the rotating motor 15 is rotated in the opposite direction, so that the gear 17 rotates with the threaded rod 21. This causes the upper and lower racks 18 to move towards each other in the slide plate 1 under the drive of the gear 17, so that the horizontal plate 3 moves away from the gear 17 along with the racks 18.This causes the connecting rod 2 to move away from the gear 17 within the slide plate 1, thereby moving the vertical plate 7 along with the connecting rod 2. This, in turn, moves the first clamping plate 8 and the second clamping plate 10, causing the first arc-shaped groove 23 and the second arc-shaped groove 16 to move along with the clamping plates 8 and 10. The rubber pad 13 also moves along with the arc-shaped grooves 23 and 16, disengaging from the bottle neck and body of the plastic bottle respectively, thus ceasing to clamp and fix the plastic bottle. When the baffle 19... When the plastic bottle contacts the inner wall of the slide plate 1, the clamping component cannot continue to move under the drive of the connecting rod 2. The gear 17 and rack 18 remain relatively fixed. Meanwhile, the rotating motor 15 continues to drive the threaded rod 21 to rotate in the opposite direction. Driven by the rotation of the threaded rod 21, the gear 17 moves along the threaded rod 21. Through the transmission of the baffle 19 and rack 18, the slide plate 1, supported by the moving wheel 20, moves within the slide groove 22 and returns to its initial position. Then, the plastic bottle is transported to the next process via the clamp.
