Description

Technical Field

[0001] This technical solution mainly involves the technical fields of "automated material handling technology" and "material conveying system optimization technology", and in particular, it relates to a device for preventing backflow and pushing bare desiccant strips into bags. Background Technology

[0002] Background Technology: In the automated assembly and production of bare strips for in vitro diagnostics, the conveying process of materials such as desiccants and bare strips is a crucial step in preventing material damage and improving production efficiency and product quality. With increasing market demand and higher requirements for production automation, traditional push-in bagging structures often suffer from problems such as unstable material feeding, material damage, and disrupted structural operation. These issues affect packaging efficiency and material integrity.

[0003] In existing solutions, materials are often dropped into aluminum foil bags to allow for the placement of bare strips or desiccants. However, the subsequent sealing and transfer of the aluminum foil bags require them to be laid flat. Some structures have also attempted to push the materials into the aluminum foil bags, but the desiccant is easily damaged during the pushing process, or the bare strips are easily carried back, causing problems with the sealing of the aluminum foil bags.

[0004] The existing technology has the following problems: Although the current technology can automatically load materials into aluminum foil bags, it cannot guarantee the efficiency and quality of the material being pushed into the aluminum foil bags, resulting in a decrease in the efficiency of automatic material loading and frequent material breakage.

[0005] 1. The existing pusher structure is simple in design and cannot adapt to materials of different shapes and sizes, making the materials easily damaged during the pushing process;

[0006] 2. Existing buffer devices and speed adjustment methods cannot accurately control the material feeding process, resulting in inaccurate material entry position in the bag, which affects the neatness and aesthetics of the packaging;

[0007] 3. Existing technical solutions have limitations in practical applications and are difficult to meet the material feeding requirements under different production conditions.

[0008] In conclusion, the development of a novel device for pushing desiccant and bagging bare strips has significant application value and practical significance. Summary of the Invention

[0009] Based on this, the technical solution mainly solves the following problems: 1) the technical problem that the material is easily damaged during the pushing process due to the simple design of traditional material pushing and bagging devices; 2) the technical problem that existing buffer devices and speed adjustment methods cannot accurately control the material pushing process, affecting the neatness and aesthetics of the packaging; 3) the technical problem that existing technical solutions have limited adaptability to material pushing requirements under different production conditions.

[0010] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for pushing desiccant strips into bags. This device features efficient conveying, stable transport, and controllable material quality.

[0011] To solve the above-mentioned technical problems, the present invention achieves its objective as follows: The present invention relates to a device for pushing desiccant strips into bags, comprising a load-bearing base, a power structure, a desiccant pushing structure, a strip pushing structure, an upper guide structure, a lower guide structure, and a connecting block.

[0012] The load-bearing base can provide a support platform for the device;

[0013] The power structure provides power for reciprocating motion;

[0014] The desiccant pushing structure includes a support groove with a length shorter than the length of the desiccant, so that the front part of the desiccant is suspended in the air;

[0015] The bare strip pushing structure is arranged in parallel with the desiccant pushing structure, and includes a C-shaped storage groove with a length shorter than the bare strip, so that the front part of the bare strip is suspended in the air.

[0016] The upper guide structure includes an upper guide boss and an upper guide groove, which are used to improve the stability of desiccant delivery;

[0017] The lower guide structure is located at the front end of the device and is fixedly connected to the upper guide structure. The lower guide structure is provided with a lower guide boss that fits with the upper guide groove, which can improve the stability of material conveying.

[0018] The connecting block fixes the desiccant pushing structure and the bare strip pushing structure to the power structure.

[0019] The beneficial effects of this invention are as follows: 1. Reduced material breakage: The desiccant and strip feeding device of this invention, through the design of the carrying groove and C-shaped storage groove, suspends the front of the material, thereby significantly reducing the risk of material breakage. 2. Improved packaging efficiency: The power structure, desiccant pushing structure, and strip pushing structure of the device work together to achieve smooth material feeding, improving the smoothness and efficiency of the packaging process. 3. Enhanced packaging neatness and aesthetics: The design of the inverted J-shaped carrying groove and C-shaped storage groove, as well as the setting of the baffle, effectively avoids the overlap and crossing of desiccant and strip inside the bag, improving the neatness and aesthetics of the packaging. 4. Improved material conveying stability: The combined use of the upper and lower guide structures improves the stability of desiccant conveying and reduces material deviation and scattering during the conveying process. 5. Enhanced adaptability: The design of this device considers the material feeding requirements under different production conditions. By adjusting the length of the carrying groove and C-shaped storage groove and the design of the guide structure, the adaptability of the device to different materials and production conditions is enhanced. 6. High structural stability: The desiccant pushing structure and bare strip pushing structure are fixed to the power structure by connecting blocks, and together with the upper guide structure and lower guide structure, they form a semi-open limiting structure, which ensures the stability of the lower desiccant pushing structure and bare strip pushing structure in reciprocating motion.

[0031] Example 1

[0032] like Figures 1-7 As shown, this application provides a technical solution in one aspect: a device for pushing desiccant strips into bags, including a weighing base 10, a power structure 20, a desiccant pushing structure 30, a strip pushing structure 40, an upper guide structure 50, a lower guide structure 60, a strip flattening structure 70, and a connecting block 80.

[0033] In this embodiment, the load-bearing base 10 can provide a support platform for the device, on which the power structure 20, the lower guide structure 60, and the bare strip flattening structure 70 are fixed.

[0034] Specifically, the load-bearing base 10 can be set up as a whole with any other structure.

[0035] In this embodiment, the power structure 20 provides power for the reciprocating motion of the desiccant pushing structure 30 and the bare strip pushing structure 40;

[0036] Specifically, the power structure 20 can be in the form of a motor driving a belt or chain, or it can be in the form of a lead screw motor driving a slide table. In this form, the power structure 20 mainly realizes reciprocating motion.

[0037] In this embodiment, the desiccant pushing structure 30 includes a support groove 31 with a length less than that of the desiccant, so that the front part of the desiccant is suspended in the air. During the bag insertion process, the desiccant falls into the bag under the action of inertial force, and the frictional force inside the bag at the front part is greater than the frictional force generated between the support groove and the desiccant.

[0038] Specifically, the bearing groove 31 has an inverted J-shaped structure, and a retaining edge 32 is provided on the side near the bare strip structure 40 to prevent the desiccant and the bare strip from overlapping inside the bag;

[0039] Specifically, the height difference between the bottom of the bearing groove 31 and the upper surface of the push bar structure 40 is greater than the height of the desiccant, which can ensure that the desiccant is in the bearing groove and prevent the desiccant height from exceeding the groove depth and being squeezed.

[0040] Specifically, the upper surface of the desiccant structure 30 is also provided with a linear groove 33 that is combined with the upper guide boss 51. The depth of the linear groove 33 is 2mm and the width is 2mm. The width of the linear groove 33 is greater than the width of the desiccant.

[0041] In this embodiment, the bare strip pushing structure 40 and the desiccant pushing structure 30 are arranged in parallel. It includes a C-shaped storage groove 41 with a length less than that of the bare strip, so that the front part of the bare strip is in a suspended or drooping state. After the bare strip is delivered to the position, it enters the bag under the action of inertia. Under the action of friction, the bare strip can be prevented from being carried back.

[0042] Specifically, the bottom of the C-shaped storage compartment 41 has a notch, and the part of the C-shaped storage compartment 41 that carries the bare strip is less than 1 / 2 of the length of the bare strip, so that the front part of the bare strip fully contacts the bag body, increasing the friction between the two, and preventing the bare strip from being brought back after it is transported to the destination.

[0043] Specifically, the C-shaped storage compartment 41 has a baffle on the side near the desiccant pushing structure 30 to prevent the bare strip and desiccant from crossing and overlapping. The baffle can confine the desiccant to the area on the side of the desiccant retracting structure 30.

[0044] In this embodiment, the upper guide structure 50 includes an upper guide boss 51 and an upper guide groove 52, which are used to improve the stability of desiccant delivery;

[0045] Specifically, the upper guide boss 51 has a height of 1mm and a width of 1.5mm, which can limit the movement path of the desiccant pushing structure 30. The upper guide boss 51 and the linear groove 33 on the desiccant pushing structure 30 are in clearance fit. After the upper guide boss 51 and the lower guide structure 60 are fixed, the desiccant pushing structure 30 can only move back and forth.

[0046] Specifically, the upper guide structure 50 can be combined with the lower guide structure 60 to construct a bare strip transport channel and a desiccant transport channel.

[0047] In this embodiment, the lower guide structure 60 is located at the front end of the device and is fixedly connected to the upper guide structure 50. The lower guide structure 60 is provided with a lower guide boss 61 that is in clearance fit with the upper guide groove 52, which can improve the stability of material conveying. It is also provided with a lower guide groove 62 that cooperates with the desiccant pushing structure 30 and the bare strip pushing structure 40.

[0048] Specifically, the lower guide boss 61 and the upper guide groove 52 are fitted together with a clearance to divide the desiccant pushing structure 30 and the bare strip pushing structure 40 into two parts.

[0049] In this embodiment, the connecting block 80 includes an upper connecting block 81 and a lower connecting block 81. The desiccant pushing structure 30 and the bare strip pushing structure 40 are fixed to the power structure 20 through the connecting block 80.

[0050] Specifically, the desiccant pushing structure 30 and the bare strip pushing structure 40 can be fixed on the upper connecting block 81; specifically, at least one side of the contact surface of the upper connecting block 81 or the lower connecting block 82 is provided with a friction block, and the upper connecting block 81 and the lower connecting block 82 can be fastened to the power structure 20 through the friction block. As the power mechanism 20 is transported, it can drive the connecting block 80 to move back and forth, thereby driving the desiccant pushing structure 30 and the bare strip pushing structure 40 to move forward or backward.

[0051] Specifically, the connecting block 80, together with the upper guide structure 50 and the lower guide structure 60, forms a semi-open limiting structure. The connecting block fixes the desiccant pushing structure 30 and the bare strip pushing structure 40 to the power mechanism 20. The connecting block cooperates with the upper guide structure 50 and the lower guide structure 60 at the extended end of the device to form a push-pull limiting device, so that the desiccant pushing structure 30 and the bare strip pushing structure 40 are stably conveyed within a specific range.

[0052] In this embodiment, the sensing element can detect the position of desiccant and bare strip at specific locations to avoid the problem of missing or overlapping materials;

[0053] The specific sensing elements can also detect the position of the connecting block 80 or other structures to ensure that each movement is in place.

[0054] In addition, to facilitate the automated production of the device, a control unit and a buffer unit are also provided. The control unit controls the movement of each actuator, and the buffer unit provides hard buffering for the movement of the connecting block 80 to prevent the desiccant pushing structure 30 and the bare strip pushing structure 40 from exceeding their specific operating range. The specific implementation process will not be described in detail here.

[0055] In this embodiment, the bare strip flattening structure 70 includes a reciprocating element 71 and a pressure strip 72. The reciprocating element 71 is fixed on the load-bearing base 10 and can drive the pressure strip 72 on it to reciprocate, so as to prevent the bare strip from falling off the C-shaped storage groove 41.

[0056] The desiccant strip feeding device in this embodiment can achieve a close arrangement of the desiccant pushing structure and the strip pushing structure. Based on the innovative design of the conveying component structure, it can prevent the desiccant or strip from leaving the track and protect the integrity of the material during the conveying process. At the same time, based on the innovation of the bearing tank and storage tank, it can prevent the desiccant and strip from being carried back after being conveyed to the designated position, thus improving the efficiency of operation.

[0057] Example 2

[0058] Another aspect of the present invention provides a device for pushing desiccant and bare strip into bags based on rotary conveying technology, comprising a load-bearing base, a rotary power structure, and a partition plate structure;

[0059] In this embodiment, the rotary power structure provides rotary power for the rotational movement of the device. It includes a rotary conveyor belt with spaced material supports to keep the desiccant and bare strips stable during the conveying process.

[0060] Specifically, the material racks are adjustable, and the rack spacing can be adjusted according to the length of the desiccant and the bare strips;

[0061] Specifically, the material support is deeper than the bare strip and the thickness of the desiccant, which can prevent the material from being squeezed during transportation.

[0062] In this embodiment, the separator structure is located at the front end of the bag opening and can receive bare strips and desiccant from the material tray;

[0063] Specifically, the partition structure includes partitions that can confine the bare strips and desiccant within a specific range, preventing them from overlapping;

[0064] Specifically, the top of the divider structure is equipped with a guide section, which allows the bare strip or desiccant to be smoothly inserted into the aluminum foil bag.

[0065] The device for pushing desiccant and bare strip into bags based on rotary conveying technology in this embodiment can achieve stable and efficient conveying of bare strips and desiccant, and can also convey bare strips and desiccant separately and at intervals to avoid material overlap.
