Description

Technical Field

[0001] This application relates to the field of template conveying equipment, and more particularly to a horizontal template circulation system. Background Technology

[0002] Laundry detergent pod production equipment plays a vital role in the modern laundry industry, with its efficient and precise production methods significantly enhancing the quality and market competitiveness of laundry products. As a core component of the production line, the horizontal template circulation system is responsible for the conveying and positioning of the molds, directly impacting product molding quality and production efficiency. In recent years, with increasing market demand and technological advancements, the research and optimization of the horizontal template circulation system has become a key aspect in improving the performance of laundry detergent pod production equipment.

[0003] Currently, chain drive mechanisms are widely used in the industry to achieve the cyclical transport of templates. Specifically, by connecting a chain to the template, the template moves cyclically along a track under the drive of a transmission sprocket. In addition, some equipment uses synchronous belt drives or rack and pinion drives to improve transmission accuracy and reliability. These technologies are widely adopted in practical applications to meet the positioning accuracy and stability requirements during template transport. Nevertheless, these solutions still face many challenges in actual use.

[0004] In existing technologies, horizontal template circulation systems using chain drives generally suffer from a decline in transmission accuracy. After long-term operation, chains are prone to wear and elongation, leading to misalignment of the template and consequently affecting the quality of the atomized beads. Furthermore, the open chain structure makes it easy for foreign objects to get stuck, causing chain jams and increasing downtime for maintenance. In addition, the segmented connection characteristic of the chain means that partial damage requires complete replacement, resulting in high maintenance costs and time consumption. Therefore, designing a template conveying system with stable transmission accuracy, strong anti-interference capabilities, and ease of maintenance has become an urgent technical problem to be solved. Summary of the Invention

[0005] In order to achieve stable transmission accuracy, strong anti-interference and easy maintenance of the template conveying system, this application provides a horizontal template circulation system.

[0006] The horizontal template circulation system provided in this application adopts the following technical solution:

[0007] A horizontal template loop system, comprising:

[0008] The frame has a closed-loop track in its vertical plane;

[0009] Multiple template components are distributed circumferentially along the loop track, and each template component is slidably connected to the loop track;

[0010] A screw mechanism is arranged at the rack, which covers a partial area of the circulating track and is used to drive the template assembly to move, and the template assembly is provided with a threaded matching part used to engage with the screw mechanism;

[0011] In the area covered by the screw mechanism, the threaded matching parts of several template assemblies engage with the screw mechanism and achieve active propulsion;

[0012] Outside the area covered by the screw mechanism, a continuous pushing power chain is formed between several template assemblies, and the whole continuous pushing chain achieves propulsion under the pushing action of the template assembly sent out from the area covered by the screw, so as to achieve the purpose of synchronous operation of all template assemblies of the circulating track.

[0013] By adopting the above technical scheme, the screw mechanism only covers a partial area of the circulating track, can accurately drive the template assembly in the area to move, ensures the stability of transmission accuracy, and avoids the problem of inaccurate positioning caused by wear of the traditional chain transmission. At the same time, the screw mechanism and the threaded matching part of the template assembly achieve engagement transmission, effectively reduces the interference of foreign matters, improves the anti-interference ability of the system, and reduces the risk of chain jamming failure. In addition, the template assemblies outside the area covered by the screw mechanism form a continuous pushing power chain, and the template assemblies are driven to operate synchronously by the pushing action of the template assembly sent out, and there is no connecting member such as chain between adjacent template assemblies, which not only simplifies the structure, but also facilitates the quick replacement of the mold, greatly reduces the maintenance cost and downtime.

[0014] Preferably, the rack comprises two oppositely arranged vertical plates, the circulating track comprises two groups and is symmetrically distributed at the two vertical plates, and the template assembly is provided with a pulley in sliding connection with the circulating track.

[0015] By adopting the above technical scheme, the rack is composed of two oppositely arranged vertical plates, and the circulating track comprises two groups and is symmetrically distributed at the two vertical plates. This symmetrical design can effectively improve the stability of the template assembly during the circulating process and reduce the possibility of running deviation. At the same time, the template assembly is provided with a pulley in sliding connection with the circulating track. The introduction of the pulley significantly reduces the frictional resistance between the template assembly and the circulating track, so that the movement of the template assembly is more smooth, thereby improving the transmission efficiency and reliability of the whole system.

[0016] Preferably, the screw mechanism comprises a plurality of screw bodies respectively rotationally connected at the two vertical plates and a linkage assembly used to drive the screw bodies to rotate synchronously, the circulating track comprises two horizontally distributed horizontal segments and two connection segments used to connect the ends of the horizontal segments, and the axis of the screw assembly is parallel to the extension direction of the horizontal segment.

[0017] By adopting the technical scheme, the screw mechanism adopts a plurality of screw bodies respectively rotationally connected at the two vertical plates and a linkage assembly for driving the screw bodies to rotate synchronously, so that accurate transmission of the template assembly on the circulating track can be realized, and the problem of precision reduction caused by wear of the traditional chain transmission can be avoided. Meanwhile, the screw mechanism covers a local area of the circulating track, and only driving propulsion power needs to be provided in the area, and the rest of the area relies on the continuous extrusion propulsion force chain between the template assemblies to realize propulsion, so that power loss is effectively reduced and transmission efficiency is improved. In addition, the circulating track is designed to include two horizontally distributed horizontal sections and two connecting sections for connecting the ends of the horizontal sections, so that the template assembly can realize stable and continuous circulating motion on the closed track, and the operation reliability and anti-interference capability of the system are further improved. In the technical means in the present claim, by arranging a plurality of screw bodies and making the axes of the screw bodies parallel to the extension direction of the horizontal section, uniform stress and stable propulsion of the template assembly on the horizontal section can be ensured, and a structural basis is provided for subsequent multi-point synchronous driving.

[0018] Preferably, the circulating track is arranged on the inner side of the vertical plate, and the screw body is arranged on the outer side of the vertical plate.

[0019] By adopting the technical scheme, the circulating track is arranged on the inner side of the vertical plate, and the screw body is arranged on the outer side of the vertical plate, so that the screw mechanism and the sliding path of the template assembly are separated in space. This layout effectively avoids the interference of the screw mechanism on the sliding motion of the template assembly, and reduces the possibility of foreign matter entering the screw mechanism, thereby improving the operation stability of the system. In addition, this design also facilitates the maintenance and repair of the screw mechanism, and the screw body can be operated without disassembling the template assembly, which significantly reduces the maintenance difficulty and downtime.

[0020] Preferably, the threaded matching part is a cylindrical slider, and the slider is engaged with the thread groove on the surface of the screw body.

[0021] By adopting the technical scheme, the slider is engaged with the thread groove on the surface of the screw body, so that the template assembly can realize accurate position control under the drive of the screw mechanism, and the problem of positioning misalignment caused by wear in the traditional chain transmission is avoided, thereby improving the motion accuracy and stability of the template assembly. In addition, the design of the cylindrical slider simplifies the matching structure with the screw body, facilitates disassembly and maintenance, and reduces the maintenance cost and time of the system.

[0022] Preferably, the vertical plate is provided with a bearing seat for rotationally connecting with the screw body, and a notch is formed at the top of the bearing seat to allow the threaded matching part to enter and exit.

[0023] By adopting the technical scheme, the bearing seat can effectively support the screw body and ensure stable rotation, avoiding loosening or deviation caused by long-time operation, thereby improving the reliability of the transmission system. The notch designed on the top of the bearing seat enables the threaded matching part on the template assembly to smoothly transition when entering and exiting the screw mechanism, avoiding the occurrence of jamming phenomenon, further improving the running smoothness and positioning accuracy of the template assembly on the circulating track. This structure design simplifies the disassembly and assembly process of the template assembly, facilitates maintenance and replacement, reduces system failure rate, and prolongs the overall service life.

[0024] Preferably, the plurality of screw bodies are arranged at positions at both ends of the horizontal section.

[0025] By adopting the technical scheme, the screw body arranged at positions at both ends of the horizontal section can realize uniform force pushing of the template assembly on the circulating track. Specifically, this layout makes the driving of the screw mechanism on the template assembly more balanced, avoiding the uneven power transmission problem that may be caused by single position driving, thereby improving the running stability of the template assembly in the circulating track. Combined with the meshing transmission characteristics between the screw mechanism and the template assembly, this distribution further improves the transmission accuracy of the system, reduces the risk of wear caused by excessive local stress, and prolongs the service life of the equipment. In addition, this design also optimizes power distribution, reduces energy loss, and improves overall operation efficiency.

[0026] Preferably, the linkage assembly comprises:

[0027] A driving shaft and a driven shaft, which are parallel to each other and are rotatably connected between the two vertical plates;

[0028] A synchronous belt, which is sleeved between the driving shaft and the driven shaft and realizes meshing transmission;

[0029] A driving member for driving the driving shaft to rotate;

[0030] A transmission shaft for connecting two screw bodies at the same vertical plate;

[0031] A bevel gear set connected between the driven shaft and the transmission shaft to realize transmission between the transmission shaft and the driven shaft.

[0032] By adopting the parallel arrangement of the driving shaft and the driven shaft and the meshing transmission of the synchronous belt, precise synchronous rotation of each screw body in the screw mechanism can be achieved, so that smooth movement of the template assembly on the circulating track is ensured, and transmission accuracy and positioning accuracy are effectively improved. At the same time, the synchronous belt transmission mode operates in a closed manner, avoiding the risk of foreign matter being stuck, significantly improving the anti-interference ability of the system and reducing the failure rate. In addition, the driving member drives the driving shaft to rotate, and the power is transmitted to the transmission shaft through the bevel gear set, so that the two screw bodies at the same side stand can work cooperatively, further optimizing power distribution and reducing maintenance cost. The overall design not only improves the reliability of system operation, but also provides a more efficient and stable template conveying solution for the laundry bead production equipment.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. By meshing transmission of the screw mechanism and the threaded fitting part of the template assembly, precise movement of the template assembly on the circulating track is achieved, avoiding positioning deviation caused by wear of traditional chain transmission, thereby ensuring high-quality forming of laundry beads;

[0035] 2. Outside the coverage area of the screw mechanism, a stable power transmission chain is formed by the continuous extrusion and pushing action between the template assemblies, ensuring the synchronization and reliability of the entire circulating system operation, further improving production efficiency;

[0036] 3. The closed structure design of the screw mechanism effectively prevents foreign matter from invading, reduces the possibility of failure, simplifies the maintenance process, and improves the overall stability and service life of the system. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0041] The following description will be made in conjunction with the accompanying drawings Figures 1-3 The present application is further described in detail.

[0042] The embodiments of the present application disclose a horizontal formwork circulating system, referring to Figure 1 and Figure 2 , comprising a rack 2, a closed circulating track 4, a plurality of formwork assemblies 1 and a screw mechanism 3. The closed circulating track 4 is arranged at the vertical plane of the rack 2, and the plurality of formwork assemblies 1 are distributed circumferentially along the circulating track 4 and are in sliding connection with the circulating track 4. The screw mechanism 3 covers a partial area of the circulating track 4 and is used to drive the formwork assemblies 1 to move. The formwork assemblies 1 are provided with screw thread matching parts 11 for engaging with the screw mechanism 3. In the area covered by the screw mechanism 3, the screw thread matching parts 11 of several formwork assemblies 1 are engaged with the screw mechanism 3 and are actively propelled. Outside the area covered by the screw mechanism 3, a continuous pushing force chain is formed between the several formwork assemblies 1. Under the pushing action of the formwork assemblies 1 sent out from the area covered by the screw, the whole continuous pushing chain is propelled to achieve the purpose of synchronous operation of all the formwork assemblies 1 of the circulating track 4.

[0043] Specifically, the rack 2 comprises two vertically extending vertical plates 21 arranged oppositely, and the two vertical plates 21 are fixed by outer supports (not shown in the figure). The circulating track 4 is provided with two groups and is symmetrically distributed at the vertical plane of the inner side of the two vertical plates 21. The bottom of the formwork assembly 1 is provided with a pulley 12 in sliding connection with the circulating track 4. For example, the pulley 12 can adopt a ball bearing structure to reduce friction and improve running stability. The material of the pulley 12 can be selected from high-strength engineering plastics or stainless steel to adapt to different working conditions. The pulley 12 is fixed at the bottom of the formwork assembly 1 through a shaft sleeve and is limited by a pin with the formwork assembly 1 to ensure that the pulley 12 will not be separated.

[0044] Referring to Figure 2 and Figure 3 , in the embodiment, the screw mechanism 3 comprises a plurality of screw bodies 31 rotatably connected at the two vertical plates 21 respectively and a linkage assembly for driving the screw bodies 31 to rotate synchronously. The circulating track 4 comprises two horizontally distributed horizontal sections 41 and two connecting sections 42 for connecting the ends of the horizontal sections 41, and the connecting sections 42 are in the shape of semicircular arcs. The axis of the screw body 31 is parallel to the extension direction of the horizontal section 41. The screw body 31 is installed at the outer side of the vertical plate 21 through the bearing seat 22 at both ends. The top of the bearing seat 22 is provided with a gap 221 for the screw thread matching part 11 to pass through, so that the formwork assembly 1 can pass through smoothly. The structural features of the bearing seat 22 include that the outer shell is made of aluminum alloy material and the precise rolling bearing is embedded in the bearing seat 22 to ensure the smooth rotation of the screw body 31. The bearing seat 22 is fixed on the vertical plate 21 by bolts and is precisely positioned by a positioning pin.

[0045] In this embodiment, the threaded fitting part 11 is a cylindrical slider that engages with the threaded path on the surface of the screw body 31. The slider has the following structural features: it has a cylindrical outer profile, a bolt hole in the interior for connecting to the template assembly 1, and can be made of wear-resistant alloy or composite material to extend its service life. The slider has guide grooves at both ends that cooperate with the axial guide ribs of the screw body 31 to prevent the slider from shifting during transmission. In addition, the surface of the slider can be coated with a lubricating coating to further reduce frictional wear.

[0046] In this embodiment, several screw bodies 31 are installed at the upper part of the vertical plate 21 and are placed at the positions of the two ends of the horizontal section 41 of the circulating track 4 to achieve more uniform distribution of driving force. This arrangement enables the template assembly 1 to obtain more stable propulsion force when entering the coverage area of the screw mechanism 3, while avoiding the occurrence of local overload.

[0047] In this embodiment, the linkage assembly includes a driving shaft 35, a driven shaft 37, a synchronous belt 33, a driving member 36, a transmission shaft 34, and a bevel gear set 32. The driving shaft 35 and the driven shaft 37 are parallel to each other and are both transversely rotatably connected between the two vertical plates 21. The synchronous belt 33 is sleeved between the driving shaft 35 and the driven shaft 37 and achieves meshing transmission. The driving member 36 is used to drive the driving shaft 35 to rotate, and can be a servo motor or a stepper motor to achieve precise speed control. The transmission shaft 34 is connected to the two screw bodies 31 at the same vertical plate 21 through universal joints. The bevel gear set 32 is connected between the driven shaft 37 and the transmission shaft 34 to achieve transmission between the transmission shaft 34 and the driven shaft 37. For example, the bevel gear set 32 can be designed with helical bevel gears to reduce transmission noise and improve transmission efficiency.

[0048] To improve the anti-interference performance of the system, a protective cover can be added outside the coverage area of the screw mechanism 3 to prevent foreign matter from entering. The protective cover can be made of transparent plastic material to facilitate observation of the internal running state.

[0049] The implementation principle of the present application is to achieve active propulsion of the template assembly 1 through the screw mechanism 3, and to complete the overall synchronous operation of the template assembly 1 by using a continuous extrusion driving force chain. This design not only improves the transmission accuracy and stability, but also reduces maintenance costs and downtime. Compared with traditional chain transmission, the present scheme has higher reliability and durability, significantly improving the performance of the laundry bead production equipment.

[0050] In this embodiment, a buffer device is added to each template assembly 1 to reduce the impact of collision between the template assemblies 1. The buffer device can be designed with a spring or a rubber pad structure and is installed at the front and rear ends of the template assembly 1.

[0051] In another embodiment, to improve the load capacity of the system, the screw mechanism 3 adopts a multi-stage transmission design, that is, one or more intermediate transmission components are added between the screw body 31 and the mold plate assembly 1. For example, a gear transmission mechanism can be arranged between the screw body 31 and the mold plate assembly 1 to achieve a larger transmission ratio and stronger driving force. In addition, the mold plate assembly 1 is provided with a reinforcing rib structure to improve the overall rigidity and load capacity of the mold plate assembly 1.

[0052] The implementation principle of this embodiment is to significantly improve the load capacity and operation stability of the system through the application of multi-stage transmission design and reinforcing rib structure. This improvement is particularly suitable for occasions requiring high load capacity, such as large-scale laundry bead production equipment.

[0053] The above are preferred embodiments of the present application, but do not limit the protection scope of the present application, therefore: any equivalent changes made in accordance with the structure, shape, principle of the present application should be covered within the protection scope of the present application.
