Description

Technical Field

[0001] This utility model relates to the field of toothpaste production technology, and in particular to an injection device for toothpaste production that is easy to fix. Background Technology

[0002] The injection process in toothpaste production refers to the crucial step of precisely injecting the prepared toothpaste into the toothpaste tube via a metering pump or piston mechanism through pipes and nozzles. It is one of the core processes in daily chemical product filling lines. This process not only requires precise injection volume and excellent sealing, but also ensures stable alignment between the clamp holding the toothpaste tube and the nozzle to avoid problems such as leakage, uneven injection, or tube contamination. As a key process in automated toothpaste production lines that directly affects product qualification rate and packaging efficiency, the positioning accuracy, stability, and ease of operation of the injection device have a decisive impact on overall filling quality, production cycle time, and even product hygiene and safety.

[0003] Existing injection devices often use simple brackets or manual clamping to fix the nozzle and tubing, lacking a fast, reliable, and adjustable synchronous positioning mechanism. When changing tubing types or cleaning and maintenance, it is necessary to repeatedly tighten and loosen bolts, adjust the height, or recalibrate the nozzle position, which is cumbersome and time-consuming. This directly leads to reduced production efficiency, increased scrap rate, and increased frequency of manual intervention. Therefore, in view of the many shortcomings of existing toothpaste injection devices in fixing the nozzle and carrier tube, such as unstable positioning, inconvenient adjustment, poor compatibility, and easy displacement, we urgently need an innovative toothpaste production injection device that is easy to fix to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide an easy-to-fix toothpaste injection device, which solves the problem of the lack of a fast, reliable, and adjustable synchronous positioning mechanism in the prior art. When changing tube types or cleaning and maintenance, it is necessary to repeatedly tighten and loosen bolts, adjust the height, or recalibrate the nozzle position, which is cumbersome and time-consuming, directly leading to reduced production efficiency, increased scrap rate, and increased frequency of manual intervention.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An easy-to-fix toothpaste injection device includes a frame, a support base fixedly connected to the bottom inner side of the frame, and a plurality of support grooves formed on the top of the support base. A first arc-shaped clamp is provided on one inner side of each support groove, and a second arc-shaped clamp is fixedly connected to the other inner side of each support groove. A threaded rod is rotatably connected to one side of each first arc-shaped clamp via a rotating shaft, and one end of the threaded rod passes through a threaded groove through one side of the support base. A support plate is provided on the upper inner side of the frame, and a rotating rod is fixedly connected to the top of the support plate. A drive motor is fixedly connected to one side of the top of the frame via bolts. The top end of the rotating rod passes through the top of the frame and is connected to the output shaft of the drive motor. A nozzle is slidably connected to one side of the bottom of the support plate, and a pump body is fixedly connected to one side of the top of the support plate via bolts. The outlet of the pump body communicates with one side of the nozzle. A support box is fixedly connected to one side of the bottom of the support plate, and the inlet of the pump body communicates with the lower side of the support box.

[0006] Preferably, a slider is fixedly connected to the top of the nozzle, and the slider is slidably connected to the carrier plate through a groove.

[0007] Preferably, a protrusion is fixedly connected to one side of the slider, and the protrusion is slidably connected to the side wall of the support plate through a movable groove. A limit plate is fixedly connected to the top side of the support plate, and a limit rod is provided on the bottom side of the protrusion. Limit grooves that cooperate with the limit rod are provided on the protrusion and the limit plate, and several limit grooves are provided on the limit plate.

[0008] Preferably, all the bottom of the first arc-shaped clamps are fixedly connected to a sliding block, and the sliding block is slidably connected to the bottom of the bearing seat through a sliding groove.

[0009] Preferably, a tension spring is fitted on the bottom end of the limiting rod, and the bottom end of the limiting rod is elastically connected to the bottom of the protrusion through the tension spring.

[0010] Preferably, the outlet of the pump body is connected to a connecting pipe, and one end of the connecting pipe is connected to one side of the nozzle.

The threaded rod provides simple and reliable mechanical clamping force, eliminating the need for complex pneumatic components. Operation is intuitive and the clamping is secure. The drive motor moves the support plate, bringing the nozzle closer to the pipe opening, significantly reducing the time spent on manual adjustments. The nozzle has sliding freedom at the bottom of the support plate, allowing for precise alignment before final filling, effectively avoiding off-center filling problems caused by manufacturing tolerances or pipe installation deviations. The pump body and support box are integrated on the support plate, shortening the material supply path and reducing the risk of residue and cross-contamination. The entire device, while ensuring high positioning accuracy, significantly simplifies the changeover and maintenance process, eliminating the need for repeated disassembly of the support or recalibration of the benchmark.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] Reference Figure 1-5 A toothpaste production injection device for easy fixation includes a frame 1. A support seat 2 is fixedly connected to the bottom inner side of the frame 1, and the top of the support seat 2 has several support grooves 3. A first arc-shaped clamping plate 4 is provided on one inner side of each support groove 3, and a second arc-shaped clamping plate 6 is fixedly connected to the other inner side of each support groove 3. A threaded rod 5 is rotatably connected to one side of each first arc-shaped clamping plate 4 via a rotating shaft, and one end of the threaded rod 5 passes through one side of the support seat 2 via a threaded groove. A support plate 7 is provided on the upper inner side of the frame 1. A rotating rod 9 is fixedly connected to the top of the carrier plate 7, and a drive motor 8 is fixedly connected to the top side of the frame 1 by bolts. The top end of the rotating rod 9 passes through the top of the frame 1 and is connected to the output shaft of the drive motor 8. A nozzle 12 is slidably connected to the bottom side of the carrier plate 7, and a pump body 10 is fixedly connected to the top side of the carrier plate 7 by bolts. The outlet of the pump body 10 is connected to one side of the nozzle 12. A carrier box 18 is fixedly connected to the bottom side of the carrier plate 7, and the inlet of the pump body 10 is connected to the lower side of the carrier box 18.

[0017] In the actual working process of this conveniently fixed toothpaste production injection device, multiple toothpaste tubes to be filled are first placed sequentially into several bearing grooves 3 opened at the top of the bearing seat 2 at the bottom of the inner side of the frame 1. Each bearing groove 3 has a movable first arc-shaped clamping plate 4 on one side and a second arc-shaped clamping plate 6 fixed on the other side. Then, the operator manually rotates each threaded rod 5. One end of the threaded rod 5 is connected to the first arc-shaped clamping plate 4 through a rotating shaft, and the other end passes through the threaded groove on the side wall of the bearing seat 2. When rotated, it pushes the first arc-shaped clamping plate 4 to move inward, and works with the second arc-shaped clamping plate 6 to clamp the toothpaste tube, achieving adaptive and stable clamping of tubes of different diameters. After the tube filling is completed, the drive motor 8 fixed to one side of the top of the frame 1 is started. Its output shaft drives the rotating rod 9 that passes through the top of the frame 1 to rotate, thereby driving the bearing fixed thereto. The carrier plate 7 swings downwards or moves horizontally, bringing the nozzle 12, which is slidably connected to the bottom of the carrier plate 7, closer to the opening of each toothpaste tube. During this process, the operator can fine-tune the nozzle 12 at the bottom of the carrier plate 7 according to the actual alignment, ensuring that it is accurately aligned with the filling opening of each toothpaste tube. After alignment, the position of the nozzle 12 is fixed by an external limiting component. Then, the pump body 10 is started, with its inlet end connected to the toothpaste paste stored in the lower part of the carrier box 18, and its outlet end connected to the nozzle 12 through a pipeline, injecting a measured amount of paste into each toothpaste tube. The entire filling process is completed under the condition that the nozzle 12 and the toothpaste tube are reliably fixed, avoiding leakage, off-center filling, or tube contamination due to vibration or displacement. After filling, the threaded rod 5 is rotated in the opposite direction to loosen the first arc-shaped clamp 4, and the finished tube can be taken out, ready for the next batch of work.

[0018] Furthermore, a slider 16 is fixedly connected to the top of the nozzle 12, and the slider 16 is slidably connected to the support plate 7 through the slide groove 17. When it is necessary to make a fine adjustment to the position of the nozzle 12, the slider 16 can slide smoothly along the slide groove 17. This structure achieves the effect of ensuring that the nozzle 12 can move in a straight line, with low resistance and precise lateral movement at the bottom of the support plate 7, thereby improving the alignment flexibility and repeatability accuracy.

[0019] Furthermore, a protrusion 22 is fixedly connected to one side of the slider 16, and the protrusion 22 is slidably connected to the side wall of the support plate 7 through the movable groove 23. A limiting plate 13 is fixedly connected to the top side of the support plate 7, and a limiting rod 14 is provided on the bottom side of the protrusion 22. A limiting groove 15 for use with the limiting rod 14 is provided on both the protrusion 22 and the limiting plate 13. Several limiting grooves 15 are provided on the limiting plate 13. After the nozzle 12 slides to the target position, the limiting rod 14 is inserted into the corresponding limiting grooves 15 on the protrusion 22 and the limiting plate 13 in sequence, which achieves the effect of quickly and reliably locking the nozzle 12 in multiple preset positions. This not only supports the adaptation of multiple specifications of toothpaste tubes, but also prevents the nozzle 12 from shifting due to vibration during the filling process.

[0020] Furthermore, all the bottoms of the first arc-shaped clamping plates 4 are fixedly connected with sliding blocks 20, and the sliding blocks 20 are slidably connected to the bottom of the bearing seat 2 through the sliding groove 21. When the rotating threaded rod 5 pushes the first arc-shaped clamping plate 4 to clamp the toothpaste tube, the sliding blocks 20 move along the sliding groove 21. This structure achieves the effect of ensuring that the movement trajectory of the first arc-shaped clamping plate 4 is straight and stable, the force is uniform, and there is no jamming or tilting, thereby improving the clamping reliability and extending the service life of the clamp.

[0021] Furthermore, a tension spring 19 is fitted on the bottom end of the limiting rod 14, and the bottom end of the limiting rod 14 is elastically connected to the bottom of the protrusion 22 through the tension spring 19. When no external force is applied, the tension spring 19 keeps the limiting rod 14 automatically inserted into the limiting groove 15. When the position of the nozzle 12 needs to be adjusted, the limiting rod 14 can be lifted upward to compress the spring and unlock it. This achieves the dual functions of self-locking and convenient unlocking of the limiting rod 14, avoiding accidental loosening and simplifying the flow adjustment.

[0022] Furthermore, a connecting pipe 11 is connected to the outlet of the pump body 10, and one end of the connecting pipe 11 is connected to one side of the nozzle 12. When the pump body 10 is working, the toothpaste paste is stably delivered to the nozzle 12 through the connecting pipe 11, which achieves the effect of ensuring reliable sealing of the material supply path, smooth flow, and no leakage or blockage, thus ensuring the consistency of filling dosage and the cleanliness of the equipment.

[0023] In summary: In the complete workflow of this easy-to-fix toothpaste production injection device, multiple toothpaste tubes to be filled are first placed sequentially into several support grooves 3 opened at the top of the support seat 2 at the bottom of the inner side of the frame 1. Each support groove 3 has a movable first arc-shaped clamping plate 4 on one side and a second arc-shaped clamping plate 6 fixedly connected to the other side. Then, the operator manually rotates each threaded rod 5. One end of the threaded rod 5 is connected to the first arc-shaped clamping plate 4 through a rotating shaft, and the other end passes through the threaded groove on the side wall of the support seat 2. When rotated, it pushes the first arc-shaped clamping plate 4 to move inward. The sliding block 20 fixed at its bottom slides smoothly along the sliding groove 21 in the support seat 2, ensuring that the movement trajectory of the clamping plate is straight and the force is even. Finally, it works in conjunction with the second arc-shaped clamping plate 6. The toothpaste tubes of different diameters are securely clamped together. After the tubes are loaded, the drive motor 8, which is fixed to one side of the top of the frame 1, is started. Its output shaft drives the rotating rod 9, which runs through the top of the frame 1, to rotate. This drives the support plate 7, which is fixed to it, to move downwards. The nozzle 12, which is slidably connected to the bottom of the support plate 7, moves closer to the opening of each toothpaste tube. During this process, the slider 16, which is fixed to the top of the nozzle 12, slides laterally along the groove 17 on the support plate 7 to achieve fine-tuning of the position of the nozzle 12. At the same time, the protrusion 22 on the side of the slider 16 moves synchronously in the movable groove 23 on the side wall of the support plate 7. When the nozzle 12 is precisely aligned with the target tube opening, the operator inserts the limiting rod 14 downwards into the corresponding limiting position on the protrusion 22 and the limiting plate 13 on the top of the support plate 7. In the slot 15, the limiting plate 13 is provided with multiple limiting slots 15 to adapt to different specifications of hoses, and the bottom end of the limiting rod 14 is elastically connected to the bottom of the protrusion 22 through the tension spring 19, which automatically maintains the locked state when there is no external force, preventing loosening due to vibration during the filling process; then the pump body 10 is started, its inlet end is connected to the toothpaste paste stored in the lower part of the carrier box 18, and the outlet end is stably transported to the nozzle 12 through the connecting pipe 11, accurately injecting the measured amount of paste into each toothpaste tube; the entire filling process is completed under the condition that the toothpaste tube is reliably clamped by the double arc-shaped clamp and the nozzle 12 is rigidly fixed by the multiple limiting mechanism, effectively avoiding leakage, off-center filling or tube contamination; after filling, the threaded rod 5 is rotated in the reverse direction, and the first arc-shaped clamp 4 is in the sliding block 20 Guided retraction releases the hose, allowing the finished product to be removed and the next batch of work to proceed. Sliding block 20 and sliding groove 21 ensure smooth movement of the clamping plate, improving clamping repeatability. The nozzle 12 can quickly switch between multiple preset positions and reliably lock, significantly improving adaptability to hoses of different specifications. Tension spring 19 provides self-locking function to limit rod 14, balancing safety and ease of operation. Connecting pipe 11 ensures smooth and sealed delivery of paste, reducing residue and cross-contamination. The entire system can achieve precise alignment and stable filling after a single clamping, eliminating the need for repeated calibration or manual intervention. This significantly shortens auxiliary time, reduces scrap rate, and effectively improves production cycle time and hygiene levels, enhancing the equipment's flexible production capacity and operational reliability.
