The leveling and cleaning mechanism of the flat-press waste cleaning and product extraction machine

Abstract

This utility model discloses a flatbed waste removal mechanism for a flatbed waste removal and product extraction machine belonging to the field of die-cutting machine technology. The flatbed waste removal mechanism includes a paper receiving rack, a transfer component, a waste removal component, and a gripper assembly. The gripper assembly drives the gripper body to move to the side of the paper receiving rack near the die-cutting mechanism through the paper receiving guide sprocket assembly. The transmission component drives the rotating shaft to rotate, causing the second clamping member to move relative to the first clamping member, thereby realizing the opening and closing of the first clamping plate and the second clamping plate. The end of the die-cut sheet is inserted between the first clamping plate and the second clamping plate. Then the rotating shaft rotates in the opposite direction, and the first clamping plate and the second clamping plate close, firmly clamping the end of the sheet and preventing it from tilting during traction. At the same time, since the first clamping member is fixedly connected to the gripper body and the second clamping member is linked with the rotating shaft, the clamping force is evenly distributed, ensuring that the die-cut sheet will not shift during the transfer process, thus improving the yield and production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically to the flatbed waste removal mechanism of a flatbed waste removal and product extraction machine. Background Technology

[0002] In modern industrial production, die-cutting waste removal and product sorting are crucial processes in industries such as packaging and printing, and the performance of the equipment directly affects product quality and production efficiency. Traditional die-cutting waste removal and product sorting equipment mostly suffers from limited functionality and low automation. Each process, such as raw material feeding, separation of finished products and waste materials, and finished product unloading, often requires extensive manual intervention. This not only results in high labor costs but also leads to low production efficiency due to the instability of manual operation, making it difficult to meet the needs of large-scale, standardized production.

[0003] Chinese invention patent publication number "CN110497460B" discloses a positioning device for a hot stamping die-cutting machine, which has a machine body, an embossing unit, and two parallel and enclosed transmission chains. The embossing unit includes a lower fixed platform and an upper movable platform. A toothed rack is connected to the transmission chains. A positioning groove is fixed at the input or output end of the embossing unit. A slide is fixed on the transmission chains. A slider is provided on the slide. The slider is connected to the toothed rack through an adjustment mechanism. The toothed rack is fixedly connected to the toothed rack. The toothed rack matches the positioning groove. When the slider moves, it contacts a moving part.

[0004] However, according to the positioning device of the hot stamping die-cutting machine, as described in paragraphs

[0021] to

[0022] of the instruction manual and the accompanying drawings, Figures 1 to 7 It is known that the positioning device of the hot stamping die-cutting machine only engages with the clamping groove at the end of the tooth bar when the sheet material is removed from the die-cutting mechanism. However, when producing non-bonded sheets, the end of the sheet material is pulled up by the tooth bar when the tooth bar pulls the sheet material, causing the die-cut sheet material to detach from the sheet material. The sheet material remains in the die-cutting device and cannot be transferred to the subsequent work station.

[0005] Secondly, when the sheet material is moved from the die-cutting stage to the tooth bar, the die-cut sheet material cannot be stably inserted into the clamping groove, causing the die-cut sheet material to shift as it moves with the tooth bar. The sheet material will remain in an offset state in subsequent workstations, resulting in a low yield.

[0006] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0007] The purpose of this invention is to provide a flat cleaning mechanism for a flat-press waste cleaning and sorting machine that can prevent the ends of the sheet material from warping and the sheet material from shifting, so as to solve the above-mentioned problems existing in the prior art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows: the flatbed waste removal mechanism of the flatbed waste removal machine includes a paper receiving rack, a transfer component, a waste removal component, and a gripper assembly. The gripper assembly pulls the die-cut sheet material from the paper receiving rack to the transfer component. The transfer component drives the sheet material to the next workstation. The waste removal component is used to remove waste material from the moving sheet material. The gripper assembly includes a paper receiving guide sprocket assembly, a gripper body linked to the paper receiving guide sprocket assembly, a first clamping member, and a second clamping member. The gripper body is rotatably provided with a swing shaft. One end of the first clamping member is fixedly connected to the gripper body, and the other end is provided with a first clamping plate. One end of the second clamping member is detachably connected to the first clamping member, and the other end is provided with a second clamping plate. The second clamping member is linked to the swing shaft, and the swing shaft is also linked to a transmission component. The paper receiving guide sprocket assembly drives the gripper body to move, and the transmission component drives the swing shaft to rotate, causing the first clamping plate and the second clamping plate to open and close.

[0009] By adopting the above technical solution: the gripper assembly drives the gripper body to move to the side of the paper receiving rack near the die-cutting mechanism through the paper receiving guide sprocket assembly. The transmission component drives the rotating shaft to rotate, causing the second clamping member to move relative to the first clamping member, thereby realizing the opening and closing of the first clamping plate and the second clamping plate. The end of the die-cut sheet is inserted between the first clamping plate and the second clamping plate. Then the rotating shaft rotates in the opposite direction, and the first clamping plate and the second clamping plate close, firmly clamping the end of the sheet and preventing it from tilting during traction. At the same time, since the first clamping member is fixedly connected to the gripper body and the second clamping member is linked with the rotating shaft, the clamping force is evenly distributed, ensuring that the die-cut sheet will not shift during the transfer process, thus improving the yield and production efficiency.

[0010] The waste removal mechanism of the above-mentioned flat-press waste removal machine can be further configured as follows: the first clamping member has an arc-shaped rotating groove in the middle, and the swivel shaft is rotatably set in the rotating groove. The first clamping member has a first mounting plate extending outward on both sides. The second clamping member has a receiving groove in the middle, which separates the second clamping member to form two sets of second mounting plates. The first mounting plate has a first positioning post extending outward on the side facing the second clamping member. The second mounting plate has a second positioning post extending outward on the side facing the first clamping member. A clamping spring is provided between the first mounting plate and the second mounting plate. One end of the clamping spring is sleeved on the outer periphery of the first positioning post, and the other end is sleeved on the outer periphery of the second positioning post. The second mounting plate and the first mounting plate are detachably connected by connecting bolts.

[0011] By adopting the above technical solution: the rotating shaft rotates within the arc-shaped rotating groove, allowing the first clamping component to remain relatively stable while the rotating shaft drives the second clamping component to rotate around the central axis of the rotating shaft. Simultaneously, the first mounting plate and the second mounting plate are detachably connected via connecting bolts, enabling flexible adjustment of the relative positions of the first and second clamping components. Clamping springs, sleeved on the first and second positioning posts, provide continuous elastic pressure for the closure of the first and second clamping plates, ensuring a smooth yet firm clamping action. This effectively prevents the sheet material from warping under high-speed traction and avoids damage to the sheet material caused by rigid clamping. Furthermore, the first and second clamping components are easy to disassemble and maintain, adapting to the clamping needs of sheets of different thicknesses and improving the applicability and stability of the mechanism.

[0012] The waste removal mechanism of the above-mentioned flat-press waste removal machine can be further configured as follows: the tooth rack body includes a tooth rack seat and two sets of tooth rack plates. The tooth rack seat has an installation cavity along the axial direction. The two sets of tooth rack plates are respectively inserted through the two ends of the installation cavity. The outer wall of the tooth rack seat has a number of first installation holes connected to the installation cavity. The tooth rack plates have second installation holes corresponding to the first installation holes. The first installation holes and the second installation holes are detachably connected by connecting bolts.

[0013] By adopting the above technical solution, the toothed plate seat provides a stable and precise installation foundation for the two sets of toothed plates through its axially opened installation cavity. The toothed plates pass through both ends of the installation cavity and are detachably connected through the first installation hole, the second installation hole, and the connecting bolts. This allows the installation position of the toothed plates to be flexibly adjusted and fixed according to actual production needs, simplifying the assembly and maintenance process of the toothed plate body. It also ensures the structural stability and relative positional accuracy of the toothed plates during high-speed operation, effectively preventing clamping deviations caused by loose parts. This ensures the smoothness and precision of the plate traction process and improves the adaptability of the entire waste removal mechanism to different specifications of plates and the reliability of long-term operation.

[0014] The waste removal mechanism of the above-mentioned flat-press waste removal and sorting machine can be further configured as follows: the tooth plate includes a connecting part, a rotating part, and a translating part. The connecting part is inserted into the mounting cavity. The rotating part is provided with a rotating block. The rotating block has a rotating hole. Rotating bushings are fitted at both ends of the unscrewing shaft. The rotating bushings pass through the rotating hole. Limiting holes are opened in the side wall of the rotating block and connected to the rotating hole. Limiting bolts for fixing the rotating bushings are inserted in the limiting holes. The unscrewing shaft and the rotating bushings are rotatably engaged. The translating part has a chain groove. Two sets of translating holes are connected on both sides of the translating part. A moving frame passes through the translating holes. A chain drum is rotatably engaged with the moving frame. The chain passes around the chain drum and through the chain groove, so that the tooth plate and the chain move synchronously.

[0015] By adopting the above technical solution: the toothed plate achieves precise allocation and efficient coordination of functions through the combined design of the connecting part, rotating part and translation part. The connecting part is firmly installed in the toothed plate seat, providing a reliable support foundation for the whole. The rotating part realizes the smooth rotation of the second clamping part through the cooperation of the unscrewing shaft and the rotating bushing, ensuring the precise execution of the clamping action. The translation part ensures that the toothed plate and the chain always move synchronously during high-speed operation through the meshing transmission of the chain drum and the chain, effectively preventing the sheet material deviation or traction instability caused by asynchronous speed. At the same time, it can adapt to different production rhythms and working conditions, improving the stability and reliability of the entire waste removal mechanism.

[0016] The waste removal mechanism of the above-mentioned flatbed waste removal and collection machine can be further configured as follows: the waste removal component includes a pressure plate frame, a pressure plate shaft, several sets of pressure plate supports, a pressure plate detachably connected to the pressure plate supports, a waste removal frame, a waste removal pressure rod, several sets of waste removal knife holders detachably connected to the waste removal pressure rods, and waste removal knives detachably connected to the waste removal knife holders. One end of the pressure plate is detachably connected to the pressure plate support, and the other end is located at the end of the rotating component opposite to the paper receiving frame. The waste removal knife cooperates with the outer surface of the transfer component to promote the waste material to move downwards from the transfer component.

[0017] By adopting the above technical solution: the pressure plate frame and pressure plate shaft provide a stable installation foundation for the pressure plate bracket. The pressure plate is fixed on the pressure plate bracket through a detachable connection, and its position and angle can be flexibly adjusted according to the specifications of the board to ensure effective pressing of the die-cut board. The waste removal frame supports the waste removal pressure rod, and the waste removal knife is detachably connected to the waste removal pressure rod through the waste removal knife seat, so that the position of the waste removal knife can be quickly changed and accurately positioned according to the waste material. The waste removal knife fits the curvature of the outer surface of the transfer component. When the waste material moves to the end of the transfer component, the waste removal knife can drive the waste material to continue to move in linkage with the transfer component, thereby guiding the waste material to the waste bin under the paper receiving rack. The die-cut finished product moves to the next station under the action of the pressure plate, realizing efficient and automatic separation of waste material and finished product, effectively avoiding the interference of waste material residue on subsequent processes, and improving waste removal efficiency and finished product quality.

[0018] The waste removal mechanism of the above-mentioned flat-press waste removal machine can be further configured as follows: the pressure plate frame includes a pressure plate slide rod, the pressure plate slide rod is slidably engaged with a pressure plate slider, the two ends of the pressure plate shaft are linked with the pressure plate slider, the pressure plate bracket has an installation notch, the pressure plate bracket is connected to the installation notch and a fixed handle is provided, the pressure plate bracket is slidably engaged with the pressure plate shaft through the installation notch and is detachably connected to the pressure plate shaft through the fixed handle.

[0019] By adopting the above technical solution, the pressure plate shaft can move flexibly along the axis of the pressure plate slide rod, realizing convenient adjustment of the overall position of the pressure plate bracket. The pressure plate bracket, through its mounting notch and sliding cooperation with the pressure plate shaft, combined with the locking of the fixed handle, allows the operator to quickly adjust and fix the specific position of the pressure rod on the pressure plate shaft and the tilt angle with the transfer component. This not only ensures the stable pressing of the pressure plate on the die-cut sheet material, effectively preventing the sheet material from shifting or warping during the waste removal process, but also enables the mechanism to flexibly adapt to the processing needs of sheet materials of different sizes and specifications, significantly improving the accuracy and production efficiency of waste removal operations, while simplifying the operation process of equipment adjustment and maintenance.

[0020] The waste removal mechanism of the above-mentioned flat-press waste removal and sorting machine can be further configured as follows: the waste removal frame is provided with a fixed pressure groove, a fixed pressure rod is inserted in the fixed pressure groove, the waste removal pressure rod is slidably engaged with the fixed pressure rod, and a reset pressure spring is sleeved on the outer periphery of the fixed pressure rod. One end of the reset pressure spring abuts against the inner wall of the fixed pressure groove, and the other end is linked with the waste removal pressure rod.

[0021] By adopting the above technical solution: the fixed pressure groove provides a stable installation base for the fixed pressure rod; the sliding fit between the waste removal pressure rod and the fixed pressure rod allows it to move flexibly in the vertical direction; the reset spring, through its design of one end abutting against the inner wall of the fixed pressure groove and the other end being linked with the waste removal pressure rod, provides a continuous elastic reset force for the waste removal pressure rod, ensuring that the waste removal knife can maintain stable pressure when in contact with the board material, and can adaptively adjust when encountering boards with uneven thickness, effectively avoiding the problem of knife damage caused by excessive pressure or incomplete waste removal caused by insufficient pressure, improving the adaptability and reliability of waste removal operations, and ensuring the thoroughness of waste removal and the quality of the finished product edge.

[0022] The waste removal mechanism of the above-mentioned flatbed waste removal and sorting machine can be further configured as follows: the transfer component includes several sets of transfer shafts, drive shafts, transfer belts, and drive motors rotatably mounted on the paper receiving rack. The drive motors are detachably connected to the paper receiving rack, the drive shafts are rotatably engaged with the paper receiving rack, the drive shafts are linked with the drive motors, the drive shafts can drive the transfer belt to rotate circumferentially, the outer circumferential surface of the transfer shafts can contact the transfer belt and support the transfer belt, and the waste removal knife has an arc-shaped notch that fits the curvature of the outer circumferential surface of the transfer belt.

[0023] By adopting the above technical solution: the drive motor drives the conveyor belt to rotate continuously in the circumference through the drive shaft, providing stable transfer power for the die-cut boards. Several sets of conveyor shafts are evenly distributed on the paper receiving rack, forming a stable support system for the conveyor belt, ensuring that the conveyor belt maintains flat operation when carrying the boards. The arc-shaped notch of the waste removal knife is precisely fitted with the curvature of the outer circumference of the conveyor belt, so that the waste removal knife can form an ideal fit gap with the surface of the conveyor belt when removing waste. This ensures that the waste is completely removed and avoids abnormal wear between the waste removal knife and the conveyor belt. The removed waste falls smoothly downwards under the action of gravity and the movement of the conveyor belt, realizing the automatic and efficient separation of waste and finished products, and improving the continuity and stability of the entire waste removal and product retrieval process.

[0024] The beneficial effects of this utility model are as follows: First, the rotation of the second clamping component via the rotating shaft in the toothed assembly enables precise opening and closing of the first and second clamping plates, effectively preventing the ends of the sheet material from lifting during traction. At the same time, combined with the continuous elastic pressing force provided by the clamping spring, it ensures the firmness of the clamping while avoiding damage to the sheet material caused by rigid clamping. Its detachable connection design facilitates maintenance and can adapt to the clamping needs of sheets of different thicknesses.

[0025] Secondly, the tooth rack body achieves flexible adjustment and stable installation of the tooth rack plate through the mounting cavity and connecting bolts, ensuring structural stability and positional accuracy during operation. The tooth rack plate, through the coordinated design of the connecting part, rotating part and translation part, ensures the precise execution of the clamping action and synchronous movement with the chain, effectively preventing traction instability caused by asynchronous speed.

[0026] Third, the waste removal component achieves stable pressure on the sheet metal and precise removal of waste through an adjustable pressure plate mechanism and replaceable waste removal blades. The sliding adjustment mechanism of the pressure plate frame and the elastic reset structure of the waste removal frame work together to ensure that the waste removal blades, with their arc-shaped notch design that fits the curvature of the conveyor belt, can thoroughly remove waste while avoiding abnormal wear. Finally, with the multi-axis support of the conveyor component and the synergistic effect of the drive belt, efficient and automatic separation of waste and finished products is achieved. The overall mechanism has the advantages of high stability, strong adaptability, and convenient operation and maintenance, which significantly improves the automation level and production efficiency of waste removal and product retrieval.

The second mounting plate 443 and the first mounting plate 433 are detachably connected by connecting bolts.

[0037] like Figure 12 As shown, the tooth rack body 42 includes a tooth rack seat 421 and two sets of tooth rack plates 422. The tooth rack seat 421 has an axially formed mounting cavity 4211, and the two sets of tooth rack plates 422 are respectively inserted through both ends of the mounting cavity 4211. The outer wall of the toothed plate 421 is connected to the mounting cavity 4211 and has several sets of first mounting holes 4212. The toothed plate 422 has second mounting holes 4221 corresponding to the first mounting holes 4212. The first mounting holes 4212 and the second mounting holes 4221 are detachably connected by connecting bolts.

[0038] The toothed plate 422 includes a connecting part 4222, a rotating part 4223, and a translating part 4224. The connecting part 4222 passes through the mounting cavity 4211. The rotating part 4223 is provided with a rotating block 4225, and the rotating block 4225 has a rotating hole 4226.

[0039] The working principle of this embodiment is as follows: The drive motor 24 drives the conveyor belt 23 to rotate via the drive shaft 22, and the paper take-up guide sprocket assembly 41 drives the toothed rack 42 to move along a predetermined path. During the movement, the transmission component 46 drives the unscrewing shaft 45 to rotate, thereby causing the second clamping component 44 to move relative to the first clamping component 43, realizing the automatic closing of the first clamping plate 431 and the second clamping plate 441, so that the first clamping component 43 and the second clamping component 44 clamp the plate. Then the chain rotates around the sprocket shaft 413, driving the toothed plate to move towards the waste removal component 3, transferring the plate onto the transfer belt 23.

[0040] Then, when the transmission component 46 drives the unscrewing shaft 45 to rotate in the opposite direction, the second clamping component 44 and the first clamping component 43 move relative to each other, releasing the plate, and the plate continues to move with the transfer belt 23.

[0041] When the sheet material moves to the waste removal component 3, the pressure plate 34 presses the die-cut finished product, and the waste removal knife 38 guides the waste edge to continue moving synchronously with the transfer belt 23, so that the die-cut sheet material and the waste edge are separated, realizing the separation of the die-cut sheet material and the waste edge.

[0042] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
