Description

Technical Field

[0001] The present invention relates to the technical field of nail cartridges, and particularly to a device for loading primer into nail cartridges and a loading method thereof. Background Art

[0002] As a special ammunition dedicated to nail guns (also known as nail drivers), nail cartridges play a crucial role in modern industrial production and various construction scenarios. By generating high-pressure gas through explosion, it can shoot nails into the target object at high speed and precision to achieve functions such as fastening and connection. Therefore, it is widely used in many fields such as construction, interior decoration, and furniture manufacturing, and has become an important tool for improving work efficiency and ensuring construction quality.

[0003] In the production process of nail cartridges, the primer loading (i.e., primer introduction) process has changed from traditional manual loading to mechanical equipment-assisted loading. Specifically, the currently common mechanical equipment-assisted loading method is as follows: a plurality of uniformly arranged through holes are provided on the medicine plate, and primer is pre-filled in these through holes; at the same time, a plurality of uniformly arranged mounting holes are opened on the sleeve plate, the nail cartridges are placed with the openings facing upwards in the mounting holes, and then the through holes of the medicine plate are made to correspond to the mounting holes of the sleeve plate one by one to complete the primer loading operation. This improvement compared with traditional manual loading has successfully achieved single-batch primer introduction and has improved the production efficiency to a certain extent.

[0004] However, the improvement in the production efficiency of this method is relatively limited, and it still seems powerless in the face of large-scale production requirements. If multiple devices are used for production simultaneously, although it can meet the production efficiency requirements to a certain extent, the subsequent high equipment cost and the need for a larger production space will undoubtedly further increase the overall production cost, resulting in low economic benefits. In addition, during the existing mechanical equipment-assisted loading process, there is also the problem of unstable primer loading accuracy, which may affect the performance consistency of nail cartridges. In some application scenarios with extremely high quality requirements for nail cartridges, this defect is particularly prominent. At the same time, the maintenance and debugging of the equipment are also relatively complex, and the downtime for maintenance will further reduce the actual production efficiency and increase the operating cost of the enterprise. Summary of the Invention

[0005] The present invention aims to provide a device for loading primer into nail cartridges and a loading method thereof to solve the problems of low production efficiency and high production cost existing in the current primer loading of nail cartridges.

[0006] To achieve the above object, the present invention adopts the following technical solution: A loading method for loading primer into nail cartridges includes the following steps:

[0007] Step 1: The template plate loaded with nail cartridges and the medicine plate loaded with primer are respectively conveyed to the primer unit of the primer device. The primer device has two groups of primer units. The template plate and the medicine plate are respectively centered, positioned and fixed. A primer coordinate system is established with the center of the medicine plate as the origin. The medicine plate is located in the XOY plane, and the conveying direction of the medicine plate is the positive direction of the Y axis;

[0008] Among them, the distance a between adjacent rows or columns of mounting holes on the template plate is twice the distance b between adjacent rows or columns of through holes on the medicine plate;

[0009] Step 2: At the first group of primer units, the first template plate is primed for the first time. The medicine plate is moved a distance b in the positive direction of the X axis and a distance b in the negative direction of the Y axis, and then the primer unit fills the primer;

[0010] Step 3: The first template plate leaves the first group of primer units and is conveyed to the second group of primer units. The first template plate is primed for the second time. The medicine plate is moved a distance b in the negative direction of the X axis and a distance b in the positive direction of the Y axis, and then the primer unit fills the primer. Thus, the loading of the first template plate is completed;

[0011] Step 4: At the first group of primer units, the second template plate is primed for the first time. The medicine plate remains unchanged in the X-axis position and is moved a distance b in the positive direction of the Y axis, and then the primer unit fills the primer;

[0012] Step 5: The second template plate leaves the first group of primer units and is conveyed to the second group of primer units. The second template plate is primed for the second time. The medicine plate remains unchanged in the X-axis position and is moved a distance b in the negative direction of the Y axis, and then the primer unit fills the primer. Thus, the loading of the second template plate is completed.

[0013] The principle and advantages of this solution are:

[0014] 1. Doubled production efficiency:

[0015] During the production process of loading nail cartridges, the unique 2:1 spacing ratio (a = 2b) design of the template plate and the medicine plate, combined with the alternating operation of two groups of primer units, successfully constructs an efficient loading mode of "one medicine plate for two template plates". In the actual operation process from Step 2 to Step 5, the medicine plate realizes precise displacement in the plane with the help of the accurately constructed X / Y axis coordinate system.

[0016] Specifically, according to the set program, the medicine board can move precisely along the X-axis and Y-axis, and the moving distance is strictly set to b, enabling a single medicine board to complete the loading operation of two sets of plates in an orderly manner. The cooperation and close connection between the two sets of primer units achieve continuous and uninterrupted operation. In the traditional single-device single-time loading mode, assuming that 100 sets of plates can be loaded per hour, after adopting this solution, since the double number of sets of plates can be loaded per unit time, the output directly increases to more than 200 per hour, and the production efficiency has achieved a significant increase of more than 100%.

[0017] The above solution not only greatly improves the production efficiency but also effectively avoids the problem of space occupation brought by the traditional multi-device parallel production mode. Through the optimized design of the distance between the medicine board and the set of plates, the production area can be saved by more than 30%. This is undoubtedly a major benefit for those enterprises with limited production site space and high rental costs, achieving a significant increase in production capacity without expanding the site scale. At the same time, the equipment procurement cost is also effectively controlled, without the need to purchase multiple devices, reducing a large amount of capital investment.

[0018] 2. Improvement of loading accuracy:

[0019] In step 1, a three-dimensional coordinate system is established with the center of the medicine board as the origin, providing an accurate positioning reference for the entire loading process. In steps 2 and 4, the medicine board makes precise displacements (distance b) along the X-axis and Y-axis. At the same time, combined with the multiple relationship of the spacing of the mounting holes of the set of plates, it can accurately ensure that the axial deviation between the primer and the opening of the nail gun cartridge is less than 0.1 mm each time of loading. In this way, the distribution of the primer in the nail gun cartridge is more uniform, significantly improving the uniformity of the charge.

[0020] 3. Optimization of equipment utilization rate:

[0021] The key to improving the equipment utilization rate in this solution is the cooperative working mechanism of the two primer units. In steps 3 and 5, when the first set of primer units successfully completes the first loading of the set of plates, the second set of primer units can immediately connect seamlessly for the secondary loading operation. This closely coordinated working mode greatly optimizes the production rhythm.

[0022] At the same time, during the entire loading process of the medicine board, it only needs to perform regular coordinate displacements according to the pre-set program. For example, in step 4, it moves a distance b along the Y-axis. This simple and regular operation method avoids the complex process of frequently replacing the positioning die of the traditional equipment, significantly shortening the equipment debugging time.

[0023] 4. Strengthening of quality control:

[0024] Through the establishment of a standardized coordinate system, all parameters of the entire loading process have achieved digital control, enabling real-time and precise monitoring of the displacement deviation of the X / Y axes. The double-loading process in Step 2-3 or Step 4-5 also effectively eliminates the edge effects that may occur during a single loading process through a unique misalignment compensation mechanism. In actual production, it can ensure that the loading amount of the priming charge for each nail gun cartridge is nearly consistent, greatly improving the consistency and stability of product quality.

[0025] 5. Reduction in production costs:

[0026] This solution is based on double priming units and displacement adjustment at each group of priming units for priming charge loading, significantly improving the production efficiency of the priming equipment. A single priming device can meet the production capacity requirements without the need to use multiple devices, effectively reducing equipment costs and energy consumption costs. At the same time, the displacement adjustment at each group of priming units reduces the demand for the overall loading operation space. The equipment does not occupy too much space in the workshop, reducing workshop costs and enhancing the comprehensive economic benefits of the enterprise.

[0027] 6. Reduction of manual participation and reduction of production safety risks:

[0028] The priming charge is a dangerous chemical that is flammable and explosive. Frequent manual contact with the priming charge may easily trigger serious safety accidents such as explosions and fires with a slight carelessness. These accidents not only pose a huge threat to the lives and safety of operators but may also cause serious damage to production facilities, bringing huge economic losses to the enterprise. In the loading method of this solution, the priming process is mainly automatically completed by the equipment. Workers only need to perform initial settings before the equipment starts and conduct simple monitoring during operation. This greatly reduces the direct contact time and frequency between workers and the priming charge, fundamentally reducing the possibility of safety accidents caused by manual operation errors. In the production workshop, even in the event of unexpected situations such as equipment failures, due to the isolation of workers from the priming charge, major safety accidents can be effectively avoided, ensuring the safety and stability of the entire production environment.

[0029] Furthermore, the sleeve plate is located below the medicine plate. In Step 2, the nail gun cartridges in the rear half part of the sleeve plate at the first group of priming units are covered by the medicine plate for priming charge loading. In Step 4, the nail gun cartridges in the front half part of the sleeve plate at the second group of priming units are covered by the medicine plate for priming charge loading.

[0030] Beneficial effects: In Step 2, the nail gun cartridges in the rear half part of the sleeve plate at the first group of priming units are covered by the medicine plate for priming charge loading. In Step 4, the nail gun cartridges in the front half part of the sleeve plate at the second group of priming units are covered by the medicine plate for priming charge loading, minimizing the conveying distance and conveying time of the sleeve plate, making the rhythm between the two priming loadings compact, improving the priming loading efficiency of a single sleeve plate, further enhancing the production efficiency of the equipment, and reducing production costs.

[0031] The layout where the template is located below the medicine plate makes full use of the vertical space of the equipment. In a limited production space, this vertical setting reduces the floor area of the equipment in the horizontal direction. For example, in a workshop with a relatively high ceiling but limited horizontal area, the equipment with this vertical layout can improve production capacity without increasing the horizontal floor area, saving valuable production space for the enterprise, especially suitable for production sites with tight space resources. This filling method makes the internal structure of the equipment more compact. Since the two primer units can operate on the front and rear halves of the template respectively, the overall layout of the equipment can be more optimized, reducing the redundant space between internal components and enabling the equipment to achieve more efficient production operations in a limited space.

[0032] Furthermore, in the step 2-5, each primer charge loading process of the primer unit is divided into two loading and pressing processes, and the pressing amplitude of the first time is greater than that of the second time.

[0033] Beneficial effects: Each primer charge loading process of the primer unit is divided into two loading and pressing processes. The first larger pressing amplitude can initially fill the primer charge to a rough position near the opening of the nail gun cartridge, laying a foundation for subsequent precise positioning. The second smaller pressing amplitude is to fine-tune the primer charge on the basis of the first time, so that it can reach the ideal loading position more accurately. The step-by-step pressing mode effectively avoids the risk that when pressing in place at one time, due to excessive pressure and difficult to accurately control, the primer charge is instantaneously unevenly stressed, resulting in position deviation or even explosion.

[0034] There may be a certain tolerance range for the opening aperture and shape of the nail gun cartridge. Products in different batches or even the same batch may have slight differences. The first larger pressing amplitude can ensure that enough primer charge enters. The second smaller pressing amplitude can sort out and compact the excess primer charge, achieving high-precision loading while ensuring safety.

[0035] Furthermore, the aperture of the mounting hole of the template is larger than the aperture of the through hole of the medicine plate.

[0036] Beneficial effects: The aperture of the mounting hole of the template is larger than the aperture of the through hole of the medicine plate. During the primer charge loading process, it can provide a more definite positioning guide for the primer charge. When the primer charge of the medicine plate is extruded through the through hole, the larger mounting hole of the template can make the primer charge enter the target position more smoothly, reducing the deviation caused by aperture adaptation problems.

[0037] Larger template mounting holes can better receive the percussion composition when the percussion composition is extruded from the through holes of the medicine plate, reduce the scattering of the percussion composition, enable the percussion composition to enter the nail gun cartridge more concentratedly, ensure that the filling amount of the percussion composition in each nail gun cartridge is more stable, reduce the quality differences caused by the scattering of the percussion composition, further narrow the fluctuation range of the combustion efficiency of the percussion composition, and improve the stability of the quality of the nail gun cartridge products.

[0038] Further, after the medicine plate completes two loadings of the percussion composition at the first group of primer units, it continues to be conveyed to the second group of primer units to complete two more loadings of the percussion composition.

[0039] Beneficial effects: The medicine plate continuously undergoes four loadings of the percussion composition between the two groups of primer units, making full use of the operating time and space resources of the equipment. In the traditional mode, there may be situations where the equipment is idle for some time or the space is not fully utilized. This filling method enables each component of the equipment to operate efficiently throughout the production process without extra waiting time, greatly improving the production efficiency of the equipment. And it allows more percussion composition to be loaded on a single medicine plate, achieving multiple loadings, reducing the frequency of frequent replacement of the medicine plate, shortening the intermediate non-working time, and further enhancing the production capacity of the equipment.

[0040] Further, the number of through holes on the medicine plate is twice the number of mounting holes on the template.

[0041] Beneficial effects: The above setting allows more percussion composition to be loaded on a single medicine plate, achieving multiple loadings, reducing the frequency of frequent replacement of the medicine plate, shortening the intermediate non-working time, and further enhancing the production capacity of the equipment; and during the long-term use of the medicine plate, the through holes will be worn due to frequent extrusion and friction of the percussion composition. When the number of through holes on the medicine plate is twice the number of mounting holes on the template, the usage frequency of each through hole is relatively reduced, prolonging the service life of the medicine plate, reducing the replacement frequency of the medicine plate, and further saving the production material cost.

[0042] The present invention also provides a technical solution: An equipment for loading the percussion composition into the nail gun cartridge, used to implement the above-mentioned loading method for loading the percussion composition into the nail gun cartridge. A medicine plate conveying unit and a primer unit are provided on the frame. The medicine plate conveying unit is used to convey the medicine plate filled with the percussion composition, and the primer unit is used to load the percussion composition on the medicine plate into the nail gun cartridge; the medicine plate conveying unit includes a conveying structure, a positioning structure, and a lifting and moving structure; the primer unit includes a primer structure and a driving structure.

[0043] Principle and beneficial effects of this solution:

[0044] 1. Improve production efficiency:

[0045] The conveying structure, positioning structure, and lifting and moving structure of the medicine plate conveying unit achieve precise conveying and positioning of the medicine plate, reduce the deviation of the material position during the filling process, and improve the accuracy and efficiency of primer loading.

[0046] Under the action of the driving structure, the primer loading structure of the primer unit can efficiently load the percussion cap on the medicine plate into the nail gun cartridge. The driving structure provides stable power for the primer loading structure, ensuring uniform loading force and speed of the percussion cap, closely cooperating with the material conveying and positioning link, and making the entire filling process smooth and orderly. In large-scale production, this smooth primer loading operation can maintain a stable production rhythm and further improve production efficiency.

[0047] 2. Improve production quality:

[0048] The collaborative work of each unit structure ensures the stability of the filling process. The precise positioning of the medicine plate and the stable operation of the primer loading structure enable the percussion cap to be filled into the nail gun cartridge evenly and accurately. In traditional equipment, due to unstable material conveying or power fluctuations in the primer loading structure, the filling amount deviation of the percussion cap may be relatively large, affecting the performance of the nail gun cartridge. However, this equipment can control the filling amount deviation of the percussion cap within a very small range.

[0049] Precise material positioning and stable primer loading operation greatly reduce the number of defective products caused by filling errors. In the traditional filling mode, due to the offset of the template or medicine plate position, the percussion cap may not be filled accurately, resulting in a relatively high defective rate. Through optimized structural design, the defective rate of this equipment can be reduced to less than half of that of traditional equipment, reducing material waste and production costs caused by defective products and improving the overall quality of the product.

[0050] 3. Achieve safe production:

[0051] The percussion cap belongs to flammable and explosive hazardous chemicals. Frequent manual contact with the percussion cap may easily trigger serious safety accidents such as explosions and fires with a slight carelessness. These accidents not only pose a huge threat to the life safety of operators but also may cause serious damage to production facilities, bringing huge economic losses to the enterprise. After adopting this primer loading equipment, the primer loading process is mainly automatically completed by the equipment. Workers only need to perform initial settings before the equipment starts and conduct simple monitoring during the operation process. This greatly reduces the direct contact time and frequency between workers and the percussion cap, fundamentally reducing the possibility of safety accidents caused by manual operation errors. In the production workshop, even in case of unexpected situations such as equipment failures, due to the isolation of workers from the percussion cap, major safety accidents can be effectively avoided, ensuring the safety and stability of the entire production environment.

[0052] 4. Reduce production costs:

[0053] Automated medicine board conveying and an efficient medicine guiding process enable the medicine guiding device to complete more medicine guiding work for nail cartridges per unit time. The improvement of the equipment utilization efficiency means that within the same production time, the enterprise can produce more qualified products. This not only reduces the equipment depreciation cost per unit product but also increases the return on investment of the equipment. Reducing the equipment idle time gives full play to the production capacity of the equipment. Without increasing the number of equipment, the enterprise can meet the growing market demand for nail cartridges by improving the equipment utilization efficiency, avoiding the cost expenditure for additional investment in purchasing equipment due to insufficient equipment.

[0054] Further, the conveying structure includes a conveying belt line and a conveying motor for driving the conveying belt line; the positioning structure includes a forward positioning structure arranged along the conveying direction and two lateral centering structures symmetrically arranged along the conveying direction; the lifting and moving structure includes a support frame. Inside the support frame, there is a guiding frame. Inside the guiding frame, there is a fixed frame. At the bottom of the fixed frame, there is a fixed groove for accommodating the medicine board. Along the conveying direction inside the support frame, there are symmetrically arranged lifting and fixing structures. The lifting and fixing structure includes a lifting cylinder and a fixing block provided at the end of the lifting cylinder. The fixing block is provided with a receiving groove with an inward slot opening.

[0055] Further, the guiding frame is slidably connected inside the support frame, the fixed frame is slidably connected inside the guiding frame. The fixed frame is connected to the guiding frame by a lateral moving cylinder and to the fixed frame by a longitudinal moving cylinder; the number of medicine guiding units is two groups. The positions of the lateral moving cylinders in the two medicine guiding units are opposite, and the moving directions of the output shafts of the two lateral moving cylinders are opposite; the number of medicine board conveying units is two groups, and they share a set of conveying structure. The conveying structure has multiple independent conveying belt lines.

[0056] Further, the medicine guiding structure includes a support column and a first support plate slidably sleeved on the support column. The bottom of the first support plate is connected to a second support plate. The second support plate is connected with mounting blocks around its perimeter and encloses to form a mounting frame at its bottom. Inside the mounting frame, there is a detachable fixing plate. A number of medicine guiding needles are detachably connected to the fixing plate; the driving structure includes a driving cylinder. The driving cylinder is a double-stroke cylinder. At the top of the support column, there is a top plate connected to the driving cylinder. The output shaft of the driving cylinder is connected to the first support plate; there is a connecting plate between the medicine guiding unit and the support frame. The medicine guiding unit is fixed on the connecting plate. One end of the connecting plate is hinged to the support plate, and the other end is connected to a connecting block fixed on the support frame. The connecting block is provided with a slot. Inside the slot, there is an inserting block. The inserting block, the connecting block, and the connecting plate are all provided with jacks. The jacks among the three correspond to each other and are installed with fixing pins; the medicine guiding unit is also connected with a vertical lifting structure. The vertical lifting structure includes a lifting column fixed to the connecting plate and a vertical lifting cylinder fixed to the support frame. At the top of the vertical lifting cylinder, there is a support shaft. The top end of the lifting column is rotatably connected to the support shaft.

[0057] This solution also has the following beneficial effects:

[0058] 1. The conveying structure uses a belt line with a motor to output stable and precise power, avoiding material displacement:

[0059] The conveyor belt line and conveyor motor of the conveying structure can provide stable and precisely controllable power output. Compared with other transmission methods, the transmission method of the belt line has the characteristics of smooth transmission and low noise, which can effectively avoid the relative displacement between the nail cartridges and the sleeve plates, and between the primer and the primer plates during the conveying process due to vibration or impact.

[0060] 2. The positioning structure enables rapid and precise positioning of the primer plates, improving the equipment efficiency:

[0061] The positioning structure can achieve rapid and precise positioning of the primer plates. The equipment does not need to be adjusted repeatedly, reducing the idling time of the equipment, improving the usage efficiency of the equipment, and further enhancing the production efficiency. Secondly, the forward positioning structure and the lateral centering structure of the positioning structure have good versatility. The positioning components of the forward positioning structure can be adjusted according to the length and shape of different primer plates to ensure effective blocking and positioning of various primer plates. The sensors and control mechanisms of the lateral centering structure can automatically adjust the centering force and method according to the width and material characteristics of the primer plates to meet the positioning requirements of different types of primer plates; thus effectively enhancing the versatility of the equipment.

[0062] 3. The lifting structure responds quickly, achieving precise positioning and shortening the positioning time:

[0063] The response speed of the lifting cylinder is extremely fast, which can complete the lifting action in a short time, achieve rapid positioning adjustment, and greatly shorten the time required for primer plate positioning. Compared with the traditional positioning method, this solution can complete more primer loading operations per unit time, improving the working rhythm of the equipment and meeting the enterprise's demand for high-efficiency production; moreover, the precise lifting and positioning structure reduces the idling time of the equipment caused by inaccurate positioning, improves the usage efficiency of the equipment, and further enhances the production efficiency.

[0064] The primer is an inflammable and explosive substance. The shaking or displacement of the primer plates during the conveying and positioning processes may cause the leakage of the primer. Once encountering ignition sources or static electricity and other excitation factors, it is extremely easy to trigger an explosion. The precise positioning and fixing function of the lifting and moving structure ensure that the primer plates are always in a stable state throughout the primer loading process, reducing the possibility of primer leakage caused by the shaking of the primer plates, providing a key guarantee for safe production.

[0065] 4. Modular design, simple equipment maintenance:

[0066] Each conveying structure, positioning structure, and lifting structure adopts a modular design. When a fault occurs in the equipment, individual components can be maintained or replaced independently without the need for large-scale disassembly of the entire equipment.

[0067] 5. Design of the hole spacing and quantity of the template and medicine plate, combined with the regulation of the horizontal and vertical cylinders, to efficiently complete multiple medicine guiding and loading:

[0068] The spacing between adjacent rows or columns of mounting holes on the template is twice the spacing between adjacent rows or columns of through holes on the medicine plate, and the number of through holes on the medicine plate is twice the number of mounting holes on the template. This design, in coordination with the position regulation of the horizontal moving cylinder and the vertical moving cylinder on the medicine plate, enables the medicine plate to achieve two medicine guiding and loading operations at each medicine guiding unit, and a total of four medicine guiding and loading operations can be carried out for two medicine guiding units. The horizontal and vertical moving cylinders can quickly and accurately adjust the position of the medicine plate. During the medicine guiding process, after the first medicine guiding is completed, the cylinder quickly moves the medicine plate to a new position according to the hole spacing relationship between the medicine plate and the template for the next medicine guiding. This position regulation greatly shortens the interval time between each medicine guiding. Compared with manually adjusting the position of the medicine plate by hand or slowly adjusting the position of the medicine plate by relying on complex mechanical structures in traditional equipment, the cylinder combines the hole characteristics of the medicine plate and the template for regulation, can complete the position transformation in an extremely short time, ensures the compact and efficient medicine guiding process, further improves the production efficiency, and realizes higher production capacity in a limited space.

[0069] 6. The equipment has a compact structure in a limited space, improving the production task volume:

[0070] The design of the hole spacing and quantity of the template and the medicine plate, combined with the flexible regulation of the position of the medicine plate by the horizontal and vertical moving cylinders, does not require additional floor space for the equipment due to multiple medicine guiding. The medicine plate can complete multiple medicine guiding operations by adjusting its position according to the hole characteristics by the cylinder within the existing guiding frame and fixed frame structure. This means that in the same space, the equipment can achieve more production tasks, reduces the space redundancy inside the equipment, and makes the equipment structure more compact.

[0071] 7. Simplify the maintenance operation of the medicine guiding structure and reduce safety risks:

[0072] When it is necessary to replace or repair the medicine guiding needle, the vertical lifting cylinder plays a key role. Its output shaft moves upward, driving the support column to rotate upward through the support shaft. This design can quickly move the fixing plate and the medicine guiding needle originally inside the equipment to the outside, exposing them to the air. Compared with the traditional method of having to completely remove the medicine guiding unit to access the medicine guiding needle, it greatly saves the maintenance time. Through this rotation method, maintenance personnel can more easily approach the medicine guiding needle and the fixing plate, without having to perform complex operations in the narrow internal space of the equipment. Maintenance personnel can directly inspect, replace, or repair the medicine guiding needle or the fixing plate, and the operation is more intuitive and simple. This not only reduces the maintenance difficulty but also reduces maintenance errors caused by inconvenient operation, improving the maintenance quality.

[0073] The simplified maintenance operation process reduces the need for maintenance personnel to perform complex operations inside the equipment, reducing the safety risks during maintenance. In the traditional complete removal and maintenance method, maintenance personnel need to operate in the narrow internal space of the equipment, which may expose them to some dangerous components and pose a risk of injury. The improved structure enables maintenance personnel to perform most operations outside the equipment, reducing this safety hazard and ensuring the personal safety of maintenance personnel.

[0091] Embodiment 1

[0092] A loading method for loading primer into a nail gun cartridge includes the following steps:

[0093] Step 1: The sleeve plate 100 containing the nail gun cartridge and the medicine plate 200 loaded with primer are respectively conveyed to the medicine guiding unit 3 of the medicine guiding device. The medicine guiding device has two groups of medicine guiding units 3. The sleeve plate 100 and the medicine plate 200 are respectively centered, positioned and fixed. A medicine guiding coordinate system is established with the center of the medicine plate 200 as the origin. The medicine plate 200 is located in the XOY plane, and the conveying direction of the medicine plate 200 is the positive direction of the Y axis;

[0094] Among them, as Figure 2As shown, the spacing a between two adjacent rows or columns of mounting holes 101 on the template 100 is twice the spacing b between two adjacent rows or columns of through holes 201 on the medicine plate 200; the number of through holes 201 on the medicine plate 200 is twice the number of mounting holes 101 on the template 100.

[0095] Step 2: At the first set of primer units 3, perform the first priming on the first template 100. Move the medicine plate 200 a distance b in the positive X-axis direction and a distance b in the negative Y-axis direction, and then the primer unit 3 fires to load the primer.

[0096] Step 3: The first template 100 leaves the first set of primer units 3 and is transported to the second set of primer units 3. Perform the second priming on the first template 100. Move the medicine plate 200 a distance b in the negative X-axis direction and a distance b in the positive Y-axis direction, and then the primer unit 3 fires to load the primer. Thus, the loading of the first template 100 is completed.

[0097] Step 4: At the first set of primer units 3, perform the first priming on the second template 100. The medicine plate 200 remains unchanged in the X-axis position and moves a distance b in the positive Y-axis direction, and then the primer unit 3 fires to load the primer.

[0098] Step 5: The second template 100 leaves the first set of primer units 3 and is transported to the second set of primer units 3. Perform the second priming on the second template 100. The medicine plate 200 remains unchanged in the X-axis position and moves a distance b in the negative Y-axis direction, and then the primer unit 3 fires to load the primer. Thus, the loading of the second template 100 is completed.

[0099] After the medicine plate 200 completes two primer loadings at the first set of primer units 3, it continues to be transported to the second set of primer units 3 to complete two more primer loadings. That is, after the medicine plate 200 completes Steps 2 and 4, it leaves the first set of primer units 3 and continues to be transported to the second set of primer units 3, repeats the centering and positioning process, and then completes the primer loading process of Steps 3 and 5. The medicine plate 200 continuously undergoes four primer loadings between the two sets of primer units 3, making full use of the operating time and space resources of the equipment. In the traditional mode, there may be situations where the equipment is idle for some time or the space is not fully utilized. This loading method enables all components of the equipment to operate efficiently throughout the production process without extra waiting time, greatly improving the production efficiency of the equipment.

[0100] Preferably, the aperture of the mounting hole 101 of the template 100 is larger than the aperture of the through hole 201 of the medicine plate 200 to ensure that during the primer loading process, a more definite positioning guide can be provided for the primer. When the primer of the medicine plate 200 is extruded through the through hole 201, the larger mounting hole 101 of the template 100 can make the primer enter the target position more smoothly, reducing the deviation caused by aperture matching problems.

[0101] Preferably, the template 100 is located below the medicine plate 200. In step 2, the rear half of the nail shooting bullets on the template 100 at the first group of medicine guiding units 3 is covered by the medicine plate 200 for primer loading; in step 4, the front half of the nail shooting bullets on the template 100 at the second group of medicine guiding units 3 is covered by the medicine plate 200 for primer loading. This minimizes the conveying distance and conveying time of the template 100, makes the rhythm between the two medicine guiding loadings compact, improves the medicine guiding loading efficiency of a single template 100, further improves the production efficiency of the equipment, and reduces the production cost.

[0102] In steps 2-5, each primer loading process of the medicine guiding unit 3 is divided into two loading and pressing operations, and the pressing amplitude of the first time is greater than that of the second time. The first larger pressing amplitude can initially fill the primer to a rough position near the opening of the nail shooting bullet, laying a foundation for subsequent precise positioning. The second smaller pressing amplitude is to fine-tune the primer on the basis of the first time so that it can reach the ideal loading position more accurately. The step-by-step pressing mode effectively avoids the risk that when pressing in place at one time, due to excessive pressure and difficult to accurately control, the primer is instantaneously unevenly stressed, resulting in position deviation or even explosion.

[0103] Embodiment 2

[0104] An equipment for loading primer into nail shooting bullets, combined with Figures 1 - 2 As shown, it includes a frame. On the frame, there are a template conveying unit 1, a medicine plate conveying unit 2, and a medicine guiding unit 3. The template conveying unit 1 is used to convey the template 100 loaded with nail shooting bullets, the medicine plate conveying unit 2 is used to convey the medicine plate 200 loaded with primer, and the medicine guiding unit 3 is used to load the primer on the medicine plate 200 into the nail shooting bullets; a number of uniformly arranged through holes 201 are opened on the medicine plate 200, and the through holes 201 are filled with primer; a number of uniformly arranged mounting holes 101 are opened on the template 100, and the openings of the nail shooting bullets are placed upward into the mounting holes 101. In this embodiment, the mounting holes 101 on the template 100 correspond to the through holes 201 on the medicine plate 200 one by one.

[0105] Combined with Figure 3 、 Figure 4 、 Figure 5As shown, the template conveying unit 1 includes a first conveying structure 11, a first positioning structure 12 and a first lifting and moving structure 13; the first conveying structure 11 conveys the template 100 filled with nail cartridges to the first positioning structure 12, and the first positioning structure 12 determines the position of the template 100 to facilitate the accurate loading of the percussion charge subsequently. The first lifting and moving structure 13 drives the template 100 to move up and down to load the percussion charge on the template 100. The medicine plate conveying unit 2 includes a second conveying structure 21, a second positioning structure 22 and a second lifting and moving structure 23; the second conveying structure 21 conveys the medicine plate 200 filled with the percussion charge to the second positioning structure 22, and the second positioning structure 22 performs centering and positioning processing on the medicine plate 200. The second lifting and moving structure 23 drives the medicine plate 200 to move up and down to cooperate with the primer unit 3 to achieve the loading of the percussion charge.

[0106] Combined with Figure 3 、 Figure 4 As shown in the figure, the first conveying structure 11 includes a first conveyor belt line 111 and a first conveyor motor 112 that drives the first conveyor belt line 111; the second conveying structure 21 includes a second conveyor belt line 211 and a second conveyor motor 212 that drives the second conveyor belt line 211. The top of the second conveyor belt line 211 is higher than that of the first conveyor belt line 111, and the first conveyor belt line 111 is located inside the second conveyor belt line 211, so that the medicine plate 200 and the template 100 are not interfered with each other during transmission, improving the synchronous transmission efficiency. Both the first conveyor belt line 111 and the second conveyor belt line 211 use circular belts, and the circular belts can prevent the accumulation of floating medicine and reduce the explosion risk.

[0107] Combined with Figure 5 As shown, the first positioning structure 12 includes two sets of opposite side positioning structures arranged along the conveying direction. Positioning grooves 102 are provided at both ends of the template 100 along the conveying direction. The side positioning structure includes a positioning block 122 and a vertically arranged positioning cylinder 121. A positioning protrusion 123 that cooperates with the positioning groove 102 is provided on one side of the positioning block 122 facing the positioning groove 102. The positioning protrusions 123 on both sides are inserted into the positioning grooves 102 to fix the template 100 and prevent it from moving with the first conveying structure 11.

[0108] Combined with Figure 6 、 Figure 7As shown, the second positioning structure 22 includes a forward positioning structure arranged along the conveying direction and two lateral centering structures symmetrically arranged along the conveying direction; the forward positioning structure includes forward positioning plates 222 symmetrically distributed on both sides of the frame and a forward positioning cylinder 221. The forward positioning plate 222 is formed by multiple bendings and includes a first positioning plate connected to the forward positioning cylinder 221, a third positioning plate for intercepting the medicine plate 200, and a second positioning plate connecting the first positioning plate and the third positioning plate. The forward positioning cylinder 221 drives the forward positioning plate 222 to move perpendicular to the conveying direction; the lateral centering structure includes a lateral centering cylinder 223 and a U-shaped centering frame 224. L-shaped centering blocks 225 are vertically bolted to both ends of the U-shaped centering frame 224. The bottoms of the third positioning plate and the centering blocks 225 are both higher than the second conveyor belt line 211, so as to ensure that there is no movement interference with the second lifting and moving structure 23 when the medicine plate 200 is laterally positioned.

[0109] As Figure 5 shown, the first lifting and moving structure 13 includes a first lifting cylinder 131 and a lifting plate 132. The lifting plate 132 is bolted to the top of the first lifting cylinder 131. Horizontally arranged connecting cylinders 133 are also symmetrically bolted to both ends of the bottom of the lifting plate 132. The connecting cylinders 133 are connected to the adjacent side positioning structure and drive the whole side positioning structure to move along the conveying direction.

[0110] Combined with Figure 8 、 Figure 9 、 Figure 10As shown in the figure, the second lifting and moving structure 23 includes a support frame 231 connected to the frame. A guide frame 232 is provided inside the support frame 231, and a fixed frame 233 is provided inside the guide frame 232. The fixed frame 233 is composed of two opposite first fixing plates 2331 and two second fixing plates 2332. A limiting plate 234 is provided on the inner wall of the first fixing plate 2331. The limiting plate 234 and the fixed frame 233 enclose a fixing groove for accommodating the medicine plate 200. Lifting and fixing structures 235 are symmetrically provided inside the fixed frame 233 along the conveying direction. The lifting and fixing structures 235 are located outside the second conveyor belt line 211. The lifting and fixing structure 235 includes a second lifting cylinder 2351 and a fixing block 2352 provided at the end of the second lifting cylinder 2351. A receiving groove 2353 with an inward-facing notch is formed on the fixing block 2352. A first notch 2333 and a second notch 2334 are sequentially provided on the second fixing plate 2332 along the height direction. The two are connected and communicate with each other. The first notch 2333 faces the inside of the fixed frame 233 and does not penetrate the fixed frame 233. The second notch 2334 horizontally penetrates and vertically penetrates the fixed frame 233. The second lifting cylinder 2351 is located inside the first notch 2333, and the fixing block 2352 is located inside the second notch 2334. Guide blocks 236 are provided at the bottoms of both the first fixing plate 2331 and the second fixing plate 2332. The inner wall of the guide block 236 is wedge-shaped, so that the bottom of the fixing groove is in the shape of a wedge-shaped expansion opening that gradually expands downward. The medicine plate 200 has a larger error tolerance space when being lifted, reducing the operation difficulty and the equipment precision.

[0111] Combined with Figure 11 , Figure 12As shown, the drug introduction unit 3 includes a drug introduction structure 31 and a driving structure. The drug introduction structure 31 includes four support columns 311 and a first support plate 312 slidably mounted on the support columns 311. A second support plate 313 is provided at the bottom of the first support plate 312, and a transmission column 314 is connected between the two at the four corners. The second support plate 313 is bolted with mounting blocks around it, and the mounting blocks and the second support plate 313 are enclosed to form a mounting frame 315, wherein the two mounting blocks in any direction are provided with folded edges at the bottom to realize vertical support and limiting of the fixed block 2352, and a fixed plate 316 is bolted and fixed in the mounting frame 315, and a plurality of drug introduction needles 317 are detachably connected to the fixed plate 316. The driving structure includes a driving cylinder 32, which is a double-stroke cylinder. A top plate is provided at the top of the support column 311 and connected to the driving cylinder 32. The output shaft of the driving cylinder 32 is connected to the first support plate 312. The double-stroke cylinder can accurately control the descending force of the drug-introducing needle 317 to achieve two drug-introducing loadings. For the first time, the driving cylinder 32 can quickly push the drug-introducing needle 317 close to the medicine plate 200 to improve work efficiency. For the second time, the driving cylinder 32 can switch to a slow stroke to accurately control the insertion of the drug-introducing needle 317 into the medicine plate 200 and the loading of the firing medicine. It effectively avoids the potential safety hazards caused by excessive force causing damage to the medicine plate 200 or excessive pressure on the firing medicine, and also prevents the firing medicine from being effectively loaded into the nail bullet due to insufficient force, further improving the safety and reliability of the drug-introducing process.

[0112] Combination Figure 1 , Figure 3 As shown, the initial end of the sleeve conveying unit 1 is provided with a transition support unit 4 for receiving the sleeve 100, including a laterally arranged push cylinder 41 and support seat structures 42 symmetrically distributed on the two inner walls of the frame, and the number of the support seat structures 42 on each side is three, combined with Figure 14 , Figure 15As shown, the supporting seat structure 42 includes a support block 421 bolted to the frame. A U-shaped groove block 422 is provided in the middle of the support block 421. The notch of the U-shaped groove block 422 faces the inner side of the frame. A guide frame 426 is sleeved outside the U-shaped groove block 422. The bottom of the guide frame 426 is a wedge surface. A limit post 425 is provided at the upper part of the notch of the U-shaped groove block 422, and a rotating shaft 424 is provided at the lower part of the notch. A supporting block 423 is rotatably connected through the rotating shaft 424. A connecting hole is provided on the upper part of the supporting block 423 facing the limit post 425 side. The connecting hole is arc-shaped. The front end of the limit post 425 is located in the connecting hole, and a triangular protrusion is formed on the side opposite to the limit post 425. The triangular protrusion makes the top of the supporting block 423 heavier. When there is no pressing of the sleeve plate 100, under the action of gravity, the supporting block 423 rotates downward towards the inside of the frame around the rotating shaft 424 until the connecting hole abuts against the limit post 425. During specific operation, the sleeve plate 100 is conveyed by the previous process conveyor line to the lower part of the transition supporting unit 4 and gradually moves upward. During the upward movement of the sleeve plate 100, it contacts the supporting block 423, and the supporting block 423 rotates upward towards the outside of the frame around the rotating shaft 424 until the sleeve plate 100 completely passes through the transition supporting unit 4. Under the action of gravity, the supporting block 423 rotates downward around the rotating shaft 424 to reset, and when the sleeve plate 100 is placed on the supporting block 423, it is officially located on the medicine guiding device.

[0113] Combined with Figure 1 、 Figure 3 As shown, at the initial end of the medicine plate conveying unit 2, there is a receiving unit 5 for receiving the medicine plate 200. The receiving unit 5 includes a receiving lifting cylinder 51 and a receiving supporting plate 52. The receiving supporting plate 52 is bolted and fixed to the output shaft of the receiving lifting cylinder 51. During specific operation, the medicine plate 200 is conveyed by the previous process conveyor line to the upper part of the receiving unit 5. The receiving lifting cylinder 51 moves the receiving supporting plate 52 upward so that the medicine plate 200 is located on the receiving supporting plate 52. Then the receiving lifting cylinder 51 drives the receiving supporting plate 52 and the medicine plate 200 to move downward so that the medicine plate 200 is located on the second conveyor belt 211, and then the receiving supporting plate 52 is separated from the medicine plate 200.

[0114] Combined with Figure 3 、 Figure 6As shown in the figure, the drug guiding device of this solution further includes a template feeding unit 6 and a medicine plate feeding unit 7. The template feeding unit 6 includes a first vertical feeding cylinder 61 and a template separation transfer plate 62 connected thereto, as well as a first horizontal feeding cylinder 63 and a first pushing plate 64 connected thereto. The medicine plate feeding unit 7 includes a second vertical feeding cylinder 71 and a medicine plate separation transfer plate 72 connected thereto, as well as a second horizontal feeding cylinder 73 and a second pushing plate 74 connected thereto. The driving directions of the first horizontal feeding cylinder 63 and the second horizontal feeding cylinder 73 are opposite. The template 100 and the medicine plate 200 that have completed the drug guiding operation are transported to the next process equipment through the template feeding unit 6 and the medicine plate feeding unit 7, achieving intelligent and automated transfer and reducing the labor intensity of workers.

[0115] Specific working principle:

[0116] The template 100 and the medicine plate 200 that have completed the previous process are respectively received and transferred to the drug guiding device by the transition supporting unit 4 and the receiving unit 5. The template 100 is pushed by the pushing cylinder 41 onto the first conveyor belt 111. The positioning cylinder 121 located at the front drives the positioning block 122 to move upward until the positioning protrusion 123 is flush with the positioning groove 102 of the template 100. The first driving motor drives the first conveyor belt 111 to transport the template 100 to the first positioning structure 12 so that the positioning protrusion 123 is inserted into the positioning groove 102. The side positioning structure located at the rear is first driven by the connecting cylinder 133 to move horizontally. The positioning cylinder 121 drives the positioning block 122 to move upward, and then the connecting cylinder 133 drives the side positioning structure to reset as a whole. The positioning cylinder 121 then drives the positioning plate to move downward to cooperate with the positioning groove 102, and the template 100 realizes the position positioning during the loading process.

[0117] The medicine plate 200 is located on the second conveyor belt 211. The second driving motor drives the second conveyor belt 211 to transport the medicine plate 200 to the second positioning structure 22. The second lifting cylinder 2351 drives the fixing block 2352 to move downward so that the receiving groove 2353 of the fixing block 2352 is flush with the second conveyor belt 211. The forward positioning cylinder 221 drives the forward positioning plate 222 to be located above the second conveyor belt 211. During the transportation process, the medicine plate 200 first enters the receiving groove 2353 of the fixing block 2352 and then contacts the forward positioning plate 222 to realize the positioning of the transportation direction. Then, the lateral centering cylinders 223 on both sides synchronously drive the U-shaped centering frame 224 and the centering blocks 225 to move towards each other, and the two centering blocks 225 press the medicine plate 200 tightly to achieve lateral centering. Then, the lateral centering cylinders 223 and the forward positioning cylinder 221 reset and retract, and the second lifting cylinder 2351 drives the medicine plate 200 to move upward until the medicine plate 200 is located in the fixing groove and abuts against the limiting plate 234.

[0118] The first lifting cylinder 131 drives the lifting plate 132 and the sleeve plate 100 thereon to move upward until the sleeve plate 100 is in close contact with the medicine plate 200. The first lifting cylinder 131 provides bottom support for the sleeve plate 100. After the sleeve plate 100 and the medicine plate 200 are positioned, the mounting holes 101 thereon are aligned with the through holes 201. The driving cylinder 32 drives the fixing plate 316 with the primer needle 317 to move downward. The primer needle 317 passes through the through hole 201 of the medicine plate 200 and presses the priming charge filled therein downward into the nail gun cartridge of the sleeve plate 100. The downward pressing process is carried out in two stages.

[0119] After the priming charge is loaded, the driving cylinder 32 drives the primer needle 317 to reset upward. The first lifting cylinder 131 drives the sleeve plate 100 to move downward so that the sleeve plate 100 falls onto the first conveyor belt 111 again. The positioning cylinder 121 and the connecting cylinder 133 drive the positioning block 122 to disengage from the sleeve plate 100 and reset, releasing the limit fixation of the sleeve plate 100. The sleeve plate 100 is continuously conveyed by the first conveying structure 11 to the sleeve plate dispensing unit 6. The first vertical dispensing cylinder 61 drives the sleeve plate separating conveyor plate 62 to lift the sleeve plate 100 upward to make it disengage from the first conveyor belt 111. Then its first horizontal dispensing cylinder 63 drives the first pushing plate 64 to push the sleeve plate 100 horizontally to the next process conveyor line.

[0120] The medicine plate 200 with the priming charge loaded is driven by the first lifting cylinder 131 to move downward. The medicine plate 200 falls onto the second conveyor belt 211 again for conveying. When it reaches the medicine plate dispensing unit 7, the second vertical dispensing cylinder 71 drives the medicine plate separating conveyor plate 72 to move upward to lift the medicine plate 200, and the second horizontal dispensing cylinder 73 drives the second pushing plate 74 to push the medicine plate 200 horizontally to the next process conveyor line.

[0121] Embodiment 3

[0122] Due to the limited space in the production environment and the limited space occupied by the equipment, it is impossible to use multiple pieces of equipment simultaneously. To further improve production efficiency, the distance a between adjacent two rows or two columns of mounting holes 101 on the sleeve plate 100 is twice the distance b between adjacent two rows or two columns of through holes 201 on the medicine plate 200; the number of through holes 201 on the medicine plate 200 is twice the number of mounting holes 101 on the sleeve plate 100. As shown in Figure 8 In this embodiment, there are 1000 mounting holes 101 on the sleeve plate 100 and 2000 through holes 201 on the medicine plate 200.

[0123] As shown in Figure 8 、 Figure 9As shown in the figure, the guiding frame 232 is slidably connected within the support frame 231, and the fixed frame 233 is slidably connected within the guiding frame 232. A transverse moving cylinder 24 is provided on the fixed frame 233 and is connected to the guiding frame 232, and a longitudinal moving cylinder 25 is connected to the fixed frame 233; there are two sets of medicine guiding units 3, and the transverse moving cylinders 24 within the two medicine guiding units 3 are arranged in opposite positions, and the moving directions of the output shafts of the two transverse moving cylinders 24 are opposite; there are two sets of medicine plate conveying units 2, and they share a set of second conveying structure 21; there are two sets of sleeve plate conveying units 1, and they share a set of first conveying structure 11. The first conveying structure 11 has multiple independent first conveying belt lines 111, and the second conveying structure 21 has multiple independent second conveying belt lines 211; the design of multiple independent belt lines enables the medicine plates 200 and sleeve plates 100 to be conveyed to the first group of medicine guiding units 3 and the second group of medicine guiding units 3 without affecting each other when being conveyed to the distribution unit after the medicine guiding is completed. Each part has a clear division of labor, avoiding the shutdown and production suspension of the entire medicine guiding equipment and also reducing the subsequent maintenance cost.

[0124] Specific working principle:

[0125] Based on Embodiment 2, the sleeve plate 100 is first conveyed to the medicine guiding unit 3 of the first group, and the second half of the sleeve plate 100 is aligned with the medicine plate 200; the medicine plate 200 is still first conveyed to the medicine guiding unit 3 of the first group, and is centered by the second positioning structure 22 and moves upward into the fixed slot under the drive of the second lifting cylinder 2351. Since the distance between adjacent two rows or two columns of mounting holes 101 on the sleeve plate 100 is twice the distance between adjacent two rows or two columns of through holes 201 on the medicine plate 200, at this time, the through holes 201 on the centered medicine plate 200 and the mounting holes 101 on the sleeve plate 100 are staggered both horizontally and vertically. Therefore, the transverse moving cylinder 24 drives the guiding frame 232 and the fixed frame 233 and the medicine plate 200 within it to move horizontally to the right by a distance b and forward by a distance b. Then, the sleeve plate 100 is driven by the first lifting structure to move upward and press against the medicine plate 200, and the driving cylinder 32 then drives the medicine guiding needle 317 to move downward to complete the medicine guiding process.

[0126] Then, the sleeve plate 100 moves downward and lands on the first conveying belt line 111 and continues to be conveyed forward to the medicine guiding unit 3 of the second group. At this time, the first half of the sleeve plate 100 is aligned with the medicine guiding unit 3; the second sleeve plate 100 is conveyed to the medicine guiding unit 3 of the first group and is positioned and moved upward. Due to the previous medicine guiding, at this time, the empty through holes 201 on the medicine plate 200 are aligned with the nail shooting bullets on the sleeve plate 100. Therefore, the longitudinal moving cylinder 25 drives the fixed frame 233 and the medicine plate 200 to move backward by a distance b, and the horizontal position remains unchanged. The through holes 201 filled with priming charge are aligned with the nail shooting bullets on the sleeve plate 100 again to complete the medicine guiding process.

[0127] The primer unit 3 of the first group completed two primer loadings, 500 holes each time, for a total of 1000 holes in two times. At this time, there was still primer for 1000 holes left on the primer plate 200. The primer plate 200 was transported from the primer unit of the first group to the primer unit 3 of the second group for positioning and fixing. Then, before the first primer in this primer unit 3, the lateral movement cylinder 24 drove the guide frame 232, the fixed frame 233 inside it, and the primer plate 200 to move horizontally to the left by a distance b and backward by a distance b, which was opposite to the first primer operation of the primer unit 3 of the first group. Then, the front half of the first template 100 was loaded with primer. After the first template 100 was loaded, the second template 100 was transported to the primer unit 3 of the second group. Before the second primer, the longitudinal movement cylinder 25 drove the fixed frame 233 and the primer plate 200 to move forward by a distance b with the lateral position unchanged. Then, the second primer was carried out to load all the nail firing cartridges on the second template 100 with primer. At this time, the primer for 2000 holes on the primer plate 200 was also all loaded. The primer plate 200 was transported to the primer distribution unit 7 for recycling.

[0128] Example 4

[0129] On the basis of Example 2, as Figure 13 shown, in this embodiment, a connecting plate 81 is provided between the primer unit 3 and the support frame 231. The primer unit 3 is fixed on the connecting plate 81. One end of the connecting plate 81 is provided with a hinge point between the support plate, and the other end is connected with a connecting block 82 fixed on the support frame 231. A slot 83 is opened on the connecting block 82, and an insertion block 84 is arranged in the slot 83. Through holes are provided on the insertion block 84, the connecting block 82, and the connecting plate 81. The through holes among the three correspond to each other and are installed with fixing pins 85. The primer unit 3 is also connected with a vertical lifting structure. The vertical lifting structure includes a lifting column 86 fixed to the connecting plate 81 and a vertical lifting cylinder 87 fixed to the support frame 231. A support shaft 88 is arranged at the top of the vertical lifting cylinder 87, and the top end of the lifting column 86 is rotatably connected with the support shaft 88.

[0130] When the primer needle 317 needs to be replaced or repaired, the output shaft of the vertical lifting cylinder 87 moves upward, and drives the support column 311 to rotate upward through the support shaft 88. Then, through the connecting block 82, the connecting plate 81 is driven to rotate around the hinge point, exposing the fixing plate 316 and the primer needle 317 to the air. In this way, it is convenient to repair or replace the primer needle 317 or the fixing plate 316 without completely removing the primer unit 3. The overall operation is simple and fast.
