Stripping mechanism

Abstract

The utility model discloses a stripping mechanism, which is mounted on a buckling machine and comprises a telescopic cylinder and a rigid stripping plate, a cylinder body of the telescopic cylinder is fixed to the buckling machine, and a telescopic rod of the telescopic cylinder is hinged to the near end of the stripper plate. The middle of the stripper plate is hinged to the buckling machine, and the far end of the stripper plate is close to a conveying channel of the buckling machine. Under the driving of the telescopic cylinder, the stripper plate can turn over, and the far end of the stripper plate can enter the conveying channel in the turning-over process.

Description

Technical Field

[0001] This utility model mainly relates to the field of packaging equipment technology, and in particular to the material release structure in a snap-locking machine. Background Technology

[0002] Emulsion explosives are a type of industrial mixed explosive made by dispersing microdroplets of an oxidizing agent salt solution in an oil phase (fuel) medium to form a water-in-oil emulsion matrix, followed by sensitization treatment. Due to its excellent water resistance, high power, high safety, and environmental friendliness, it has become a mainstream product in modern industrial explosives. After the industrial emulsion explosive is manufactured, it needs to be packaged into strips according to specifications using a snap-locking machine (such as the technical solution disclosed in Chinese patent document CN204323736U, entitled "Snap-locking Machine for Packaging Industrial Emulsion Explosive Rolls"), and the ends of the rolls are snapped and cut to form several explosive units.

[0003] In existing technology, to detach the packaged medication vials from the clamping machine, the clamping machine is equipped with a release belt that moves with a fork plate at one end. This release belt, as it moves with the fork plate, pulls the medication vials out of the clamping machine. The process is as follows: Figures 1 to 3 As shown: In Figure 2 In the middle, the fork plate moves down, clamping the drug roll within the conveyor channel. Both ends of the roll are snapped shut and cut into individual doses. At this point, the stripper belt is in a relaxed state. Figure 3 In the middle, the fork plate moves upward, and at this time, the movable end of the stripping belt moves accordingly and is tightened. During this process, the moving path of the stripping belt crosses the conveyor channel, thereby pulling the medicine cartridge out of the conveyor channel.

[0004] While this belt-type ejector structure can help dislodge medication vials from the clipping machine, the flexible nature of the ejector belt makes it prone to swaying during operation, thus affecting the stability of the equipment. Furthermore, repeated bending of the ejector belt can lead to fatigue damage and deformation, requiring frequent replacement and impacting normal production progress.

[0005] For the reasons mentioned above, the material removal structure in the snap-fit ​​machine needs to be modified. Utility Model Content

[0006] The technical problem to be solved by this utility model is how to prevent the stripping belt from swaying during equipment operation, and how to prevent the stripping belt from fatigue damage and deformation due to repeated bending.

[0007] The following technical solution is adopted:

[0008] A stripping mechanism, installed on a clamping machine, includes a telescopic cylinder and a rigid stripping plate. The cylinder body of the telescopic cylinder is fixed to the clamping machine, and its telescopic rod is hinged to the proximal end of the stripping plate. The middle part of the stripping plate is hinged to the clamping machine, and its distal end is close to the conveying channel of the clamping machine. Driven by the telescopic cylinder, the stripping plate can flip, and its distal end can enter the conveying channel during the flipping process. Because the stripping plate is a rigid component, its flipping path is uniquely determined by the hinge point. The stripping plate achieves a fixed rotation fulcrum through the hinge at its middle part with the clamping machine. Combined with the stable drive of the telescopic cylinder, the flipping trajectory can be precisely controlled, preventing irregular swaying due to its own flexibility, significantly improving the stability of equipment operation. Simultaneously, the rigid structure of the stripping plate avoids fatigue damage and deformation of the stripping belt caused by repeated bending, greatly reducing the frequency of component replacement and minimizing the impact of downtime for component replacement on normal production progress.

[0009] As a further improvement to the above technical solution:

[0010] The stripping plates consist of three parts: a central stripping plate and two side stripping plates. The central stripping plate is located between the two cutting guide plates of the clipping machine, and the two side stripping plates are positioned on either side of the two cutting guide plates. This arrangement ensures that the effective area of ​​the stripping plates completely covers the width of the clipping machine's conveying channel—the central stripping plate corresponds to the central area of ​​the channel, and the side stripping plates correspond to the areas on either side of the channel. This avoids problems such as misalignment and jamming of the dispensing tubes caused by concentrated force points or incomplete coverage of a single stripping plate. Furthermore, the positions of the stripping plates and the cutting guide plates are mutually compatible, preventing movement interference. The coordinated action of the three stripping plates ensures more even force distribution on the dispensing tubes during the stripping process, further improving the stability and reliability of the stripping action.

[0011] The stripping plate has a clearance slit in its center, allowing the cutter of the snap-fit ​​machine to pass through. This clearance slit ensures motion compatibility between the stripping plate and the snap-fit ​​machine's cutter—when the snap-fit ​​machine cuts the drug rolls, the cutter can pass through the clearance slit to complete the cutting action, eliminating the need for additional travel or timing intervals in the equipment to accommodate the stripping plate. This simplifies the snap-fit ​​machine's workflow and ensures smooth transitions between the cutting and stripping processes. Furthermore, this structure eliminates the need to adjust the cutter's original installation position and trajectory, reducing the difficulty of adapting the stripping mechanism to existing snap-fit ​​machines.

[0012] The proximal end of the middle stripper plate is connected to the proximal ends of the two side stripper plates via a first rotating shaft. This first rotating shaft is connected to the end of the telescopic rod via a Y-shaped connector. The first rotating shaft enables the three stripper plates to form a unified, interconnected system. Combined with the force transmission function of the Y-shaped connector, the driving force of the telescopic cylinder can be synchronously transmitted to the three stripper plates through a single output end, ensuring completely synchronized flipping of the three stripper plates. This avoids problems such as uneven stripping force and damage to the pharmacy cartridges caused by asynchronous driving of the stripper plates. Furthermore, the Y-shaped connector can adapt to the connection angle between the telescopic rod and the first rotating shaft, reducing stress concentration during force transmission and improving the stability and service life of the drive structure.

[0013] The middle stripper plate is connected to the middle of the two side stripper plates via a second rotating shaft, which is then connected to the clamping machine via screws. This second rotating shaft integrates the rotation fulcrum of the three stripper plates into one unit, further ensuring the consistency of the flipping trajectory of each stripper plate and structurally eliminating movement deviations caused by fulcrum offset of a single stripper plate. The screw connection method facilitates the installation, disassembly, and maintenance of the stripper mechanism—when repair or replacement of the stripper plates is required, only the screws need to be removed to remove the second rotating shaft and the entire set of stripper plates, without requiring modifications to the main structure of the clamping machine, thus reducing maintenance costs and downtime.

[0014] The telescopic cylinder is set as the force-adjusting cylinder of the snap-fit ​​machine. By directly using the original force-adjusting cylinder of the snap-fit ​​machine as the telescopic cylinder of the unloading mechanism, this method of sharing parts can effectively simplify the equipment structure and reduce equipment costs.

Specifically, when the telescopic rod 112 is in the retracted state, the distal end of the unloading plate 12 is at its lowest point and has not entered the conveying channel 21. When the telescopic rod 112 is in the extended state, the distal end of the unloading plate 12 moves upward and enters the conveying channel 21, thereby pushing the medicine stick 3 located there away from the conveying channel 21.

[0026] Specifically, there are three stripper plates 12, including a central stripper plate 121 and two side stripper plates 122. The central stripper plate 121 is located between the two cutting guide plates 22 of the snap fastener 2, and the two side stripper plates 122 are arranged on both sides of the two cutting guide plates 22 of the snap fastener 2. More specifically, the central stripper plate 121 has a clearance slot 1211 in the middle for the cutter 23 of the snap fastener 2 to pass through.

[0027] In this embodiment, the proximal end of the central stripping plate 121 is connected to the proximal ends of the two side stripping plates 122 via a first rotating shaft 123, which is connected to the end of the telescopic rod 112 via a Y-type connector 113. The middle part of the central stripping plate 121 is connected to the middle part of the two side stripping plates 122 via a second rotating shaft 124, which is connected to the fastening machine 2 via screws.

[0028] In this embodiment, the telescopic cylinder 11 is configured as the force-adjusting cylinder of the buckling machine 2.

[0030] exist Figure 6 In the middle, the fork plate 24 moves down, clamping the medicine roll inside the conveying channel 21. Both ends of the medicine roll are snapped shut and cut into medicine sticks 3. At this time, the telescopic cylinder 11 is in a retracted state, and the far end of the stripping plate 12 is at its lowest point and has not entered the conveying channel 21. Figure 7 In the middle, the fork plate 24 moves upward, the telescopic rod 112 is in the extended state, the far end of the stripping plate 12 moves upward and enters the conveying channel 21, pushing the medicine stick 3 located there away from the conveying channel 21.
