Abstract
Description
Technical Field
[0001] This application relates to the technical field of latex glove production, and in particular to a chain positioning device for a latex glove production line. Background Technology
[0002] The production of latex gloves typically involves multiple processes on a continuous production line, including dipping, water cooling, vulcanization, drying, hemming, and demolding. Due to the complexity of the process, traditional linear production lines often require a large amount of floor space. To optimize space utilization, production lines are usually designed with a multi-layered, three-dimensional layout, using detours at the ends of the production line to achieve spatial reversal.
[0003] Currently, glove molds in production lines mainly rely on chain drive systems for transportation. In the chain turning area, the transmission direction is usually changed through the cooperation of sprockets and chains. However, after long-term use, the chain may loosen, causing it to slip relative to the sprocket during turning and resulting in axial displacement. This can lead to chain dislocation and affect the stability of the chain turning. Utility Model Content
[0004] To improve the stability of chain transmission, this application provides a chain positioning device for a latex glove production line.
[0005] This application provides a chain positioning device for a latex glove production line, which adopts the following technical solution:
[0006] A chain positioning device for a latex glove production line includes:
[0007] The limiting groups are arranged in multiple sets at intervals along the extension direction of the chain, and each limiting group includes two limiting seats respectively connected to opposite sides of the chain; and
[0008] The baffle has two baffles, which are respectively connected to opposite ends of the sprocket, and a limiting space is formed between the two baffles;
[0009] When the chain passes the sprocket, the side of the limiting seat closest to the sprocket is located in the limiting space to restrict the chain from axially moving and dislodging relative to the sprocket.
[0010] By adopting the above technical solution, and by setting a limit group and a baffle, the limiting space between the limit seat and the baffle can limit the axial movement range of the chain on the sprocket, so as to prevent the chain from dislodging due to slack or offset, thereby improving the stability of the chain drive.
[0011] Optionally, the limiting seat is annular, and two limiting seats in the same group are coaxially arranged, with the axis of the limiting seat parallel to the axis of the sprocket.
[0012] Optionally, the sprocket is connected to the baffle via a mounting base. The mounting base is provided with a first blocking seat and a second blocking seat that are sequentially distributed in a direction away from the sprocket. The baffle moves on the mounting base in a direction parallel to the sprocket axis and is confined between the first blocking seat and the second blocking seat. The mounting base has an elastic element that allows the sprocket to move toward the first blocking seat.
[0013] When the chain passes the sprocket, it has a positive state or a limit offset state; the positive state is characterized by a gap between the limiting seat and the baffle; the limit offset state is characterized by the chain pushing the baffle through the support seat, causing the baffle to move to abut against the second blocking seat.
[0014] By adopting the above technical solution, the chain can operate in both the forward and extreme offset states through the cooperation of the first stop, the second stop, and the elastic element. The elastic force of the elastic element requires the chain to overcome greater resistance when it deviates, thereby guiding the chain to move in the forward state, improving the reliability and safety of the device.
[0015] Optionally, the second blocking seat has a sensor that is linked to an alarm terminal. When the baffle comes into contact with the second blocking seat, the sensor senses a signal and transmits the signal to the alarm terminal.
[0016] By adopting the above technical solution, the sensors and alarm terminals can issue an alarm in a timely manner when the chain reaches its limit of deviation, reminding staff to intervene.
[0017] Optionally, the position of the first blocking seat on the mounting base can be adjusted along the axis parallel to the sprocket.
[0018] By adopting the above technical solution, the position of the first blocking seat is adjustable, enabling the device to adapt to chains and sprockets of different specifications, enhancing the versatility and flexibility of the device, and meeting the needs of different production scenarios.
[0019] Optionally, the position of the second stop seat on the mounting base can be adjusted along the axis parallel to the sprocket.
[0020] By adopting the above technical solution and adjusting the position of the second blocking seat, the adaptability of the device is improved.
[0021] Optionally, the sprocket is coaxially connected to a rotating shaft, and the rotating shaft is rotatably connected to a movable seat at both ends, which moves along the axis perpendicular to the sprocket on the production line frame; the movable seat at both ends of the rotating shaft is also connected to a movable frame, and the movable frame is connected to a counterweight assembly, so that the movable seat has a tendency to move in the direction of tensioning the chain.
[0022] By adopting the above technical solution, the cooperation between the movable seat and the counterweight component enables the sprocket to automatically tension the chain, reducing the offset problem caused by chain slack and further improving the stability and reliability of the chain drive.
[0023] Optionally, the counterweight assembly includes a connecting rope and a counterweight block. One end of the connecting rope is connected to the movable frame, and the other end of the connecting rope is wound onto a winder. The counterweight block is disposed on the connecting rope.
[0024] By adopting the above technical solution, the cooperation between the connecting rope and the counterweight enables the automatic tensioning function of the sprocket. The structure is simple and easy to maintain. At the same time, the winder keeps the connecting rope in a taut state, further improving the stability of the device.
[0025] In summary, this application includes at least one of the following beneficial effects:
[0026] 1. By blocking the limit seat with the baffle, the offset range of the chain is limited to the range that allows for normal operation, thus improving the stability of chain transmission;
[0027] 2. The combination of the counterweight component and the moving seat enables automatic chain tensioning, reducing manual intervention and improving production efficiency and equipment lifespan. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.
[0034] This application discloses a positioning device for chain 18 in a latex glove production line. (Refer to...) Figure 1 The positioning device for chain 18 in the latex glove production line includes a sprocket 19, a chain 18, a limiting assembly 1, and a baffle 2. The sprocket 19 meshes with the chain 18, and a rotating shaft 8 coaxially fixed to the center of the sprocket 19 and rotatably connected to the production line frame is also present. The limiting assembly 1 is connected to the chain 18, and the baffle 2 is connected to the sprocket 19. The baffle 2 limits the limiting assembly 1 to prevent the chain 18 from detaching from the sprocket 19 along its axial direction.
[0035] Reference Figure 2 and Figure 3 Specifically, multiple sets of limit groups 1 are evenly spaced along the length of the chain 18, and each set of limit groups 1 includes two limit seats 101. The limit seats 101 are disc-shaped, and a connecting shaft 13 is coaxially fixed to each limit seat 101. The limit seats 101 are connected to the chain 18 via the connecting shaft 13, making the axis of the limit seats 101 parallel to the axis of the sprocket 19. The connecting shaft 13 can be fixed to the chain 18 or rotatably connected to the chain 18. The two limit seats 101 in the same group are coaxially arranged. It should be noted that the glove mold is installed at the end of the limit seat 101 opposite to the chain 18, and the periphery of the limit seat 101 extends radially beyond the opposite sides of the chain 18 and the glove mold. Both the limit seats 101 and the connecting shaft 13 are made of rigid material.
[0036] Each sprocket 19 has two baffles 2, which are connected to the two ends of the sprocket 19 along its own axial direction via mounting bases 4. The baffles 2 are annular and coaxial with the sprocket 19, and the inner diameter of the baffles 2 is larger than the outer diameter of the shaft 8. The baffles 2 do not come into contact with the sprocket. A limiting space 3 is formed between the two baffles 2. The limiting seat 101 on the part of the chain 18 that engages with the sprocket 19 is opposite to the limiting space 3. Specifically, the limiting seat 101 is located in the limiting space 3 on the side of the limiting seat 101 that is closer to the sprocket 19 in the radial direction, so that the two baffles 2 are opposite to the limiting seats 101 on both sides of the chain 18, so that the two baffles 2 together limit the limiting seats 101 on both sides of the chain 18, preventing the chain 18 from excessively deviating along the axial direction of the sprocket 19 and disengaging from the sprocket 19.
[0037] Reference Figure 3 and Figure 4 Furthermore, each baffle 2 corresponds to two mounting seats 4, which are symmetrically mounted on the sprocket 19 along its axis to improve the stability of the baffle 2. Each mounting seat 4 includes a guide rod 41 and an extension rod 42. The guide rod 41 is fixed to the end of the sprocket 19, and its length extends parallel to the axis of the sprocket 19. The extension rod 42 is fixed to the guide rod 41 and is perpendicular to it.
[0038] A first blocking seat 5 is mounted on the guide rod 41, and a second blocking seat 6 is mounted on the extension rod 42. The baffle 2 is simultaneously slidably sleeved on the corresponding two guide rods 41 along the length of the guide rod 41, with the first blocking seat 5 being closer to the sprocket 19 than the second blocking seat 6. An elastic element 7, cooperating with the baffle 2, is also connected to the extension rod 42. This elastic element 7, in conjunction with the baffle 2, induces the baffle 2 to move closer to the first blocking seat 5. When the baffle 2 is not subjected to any other external force, it abuts against the first blocking seat 5 under the drive of the elastic element 7. In this embodiment, the elastic element 7 is a spring connecting the extension rod 42 and the baffle 2, and the spring is also sleeved on the guide rod 41. In other embodiments, the elastic element 7 can also be a spring sheet.
[0039] When chain 18 passes sprocket 19, chain 18 is in either a forward or extreme offset state. When chain 18 is in the forward state, the radial centerline of chain 18 is aligned with the radial centerline of sprocket 19, meaning that sprocket 19 and chain 18 are precisely engaged. At this time, there is a gap between baffle 2 and the corresponding limiting seat 101. When chain 18 is in the extreme offset state, the axial offset of chain 18 relative to sprocket 19 is at the maximum limit value that can maintain normal operation. At this time, the limiting seat 101 on the offset side of chain 18 pushes the corresponding baffle 2 to abut against the second blocking seat 6 to limit chain 18 from further offset. During the process of the limiting seat 101 pushing the baffle 2, it must resist the elastic force of the elastic element 7 to increase the difficulty of chain 18 offset.
[0040] In some embodiments, a sensor (not shown in the figure) is embedded in the side of the second stop seat 6 facing the baffle 2. The sensor is electrically linked to an alarm terminal. When the baffle 2 touches the second stop seat 6, the sensor transmits a signal to the alarm terminal to issue an alarm, thereby alerting the worker that the chain 18 has shifted position. The sensor can be a photoelectric sensor or a micro switch, and the alarm terminal can be an audible and visual alarm or a control box display screen of the production line.
[0041] Reference Figure 3 and Figure 4Furthermore, to improve the adaptability of the device and allow the positions of the first blocking seat 5 and the second blocking seat 6 to be adjusted as needed, both the first blocking seat 5 and the second blocking seat 6 are adjustable and movable on the mounting base 4. Specifically, the guide rod 41 is a screw-shaped rod with its axis parallel to the axis of the sprocket 19. The first blocking seat 5 is threaded onto the guide rod 41, and its position is adjusted by moving the first blocking seat 5 by the thread. The second blocking seat 6 is connected to a connecting rod 14 that slides along the axis parallel to the sprocket 19 and passes through the extension rod 42. Two nuts are threaded onto the connecting rod 14, and the two nuts are respectively opposite to the two sides of the extension rod 42. When adjusting the position of the second blocking seat 6, first slide the connecting rod 14 to move the second blocking seat 6 to the desired position, and then move the two nuts on the connecting rod 14 threadedly until they abut against the opposite sides of the extension rod 42, so that the second blocking seat 6 is limited relative to the extension rod 42.
[0042] Reference Figure 1 and Figure 2 Furthermore, the two ends of the rotating shaft 8, which are far apart from each other, are rotatably connected to movable seats 9 via bearings. The movable seats 9 are block-shaped. The rotating shaft 8 is fitted onto the frame via the movable seats 9, and the frame has guide rails 15 for the movable seats 9 to move horizontally along the axis of the vertical sprocket 19. This allows the movable seats 9 to drive the rotating shaft 8 to move laterally, so that the sprocket 19 tensions the chain 18 and reduces the radial offset of the chain 18 relative to the sprocket 19. The same movable frame 10 is fixedly connected to the movable seats 9 at both ends of the rotating shaft 8. The movable frame 10 has a U-shaped structure. A counterweight assembly 11 is connected to the movable frame 10, which gives the movable frame 10 a tendency to move in the direction of tensioning the chain 18 towards the sprocket 19.
[0043] Specifically, the counterweight assembly 11 includes a connecting rope 111 and a counterweight block 112. One end of the connecting rope 111 is fixed to the center of the moving frame 10, and the other end of the connecting rope 111 is wound onto a winder 12. The winder 12 can be installed on the frame or the ground, and the winder 12 is driven by a motor to rotate the shaft around which the connecting rope 111 is wound. At the same time, a winding shaft 16 parallel to the rotating shaft 8 is fixed on the frame. A fixed pulley 17 is coaxially rotatably mounted on the winding shaft 16. The connecting rope 111 is wound horizontally around the fixed pulley 17 and then extends downward before being wound onto the winder 12. The counterweight block 112 is fixed to the vertically extending portion of the connecting rope 111 so that the moving frame 10 is pulled closer to the winding shaft 16 by the connecting rope 111, thereby driving the sprocket 19 to tighten the chain 18. When the portion of the connecting rope 111 between the counterweight 112 and the winder 12 becomes slack, the rotating shaft of the winder 12 rotates to tighten the connecting rope 111 again.
[0044] The implementation principle of the positioning device for the chain 18 of a latex glove production line according to this application embodiment is as follows: the axial movement range of the chain 18 is limited by the cooperation between the limiting seat 101 and the baffle 2, preventing the chain 18 from axially disengaging relative to the sprocket 19. The counterweight assembly 11 automatically tensions the chain 18 to prevent the chain 18 from radially disengaging relative to the sprocket 19.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
