Description

Technical Field

[0001] This utility model relates to the field of filling equipment technology, and more specifically to an integrated ointment filling and capping device. Background Technology

[0002] Traditional solder paste filling is done manually, requiring a large workforce, resulting in high costs and low production efficiency. Existing filling methods typically employ automated machinery. For example, utility model patent CN217864884U discloses an automatic syringe solder paste dispensing device, including a device body and syringes. The device body has a control console and at least one pressurized feeding system for dispensing solder paste into the syringes. The device body also has a synchronous moving mechanism matching the number of pressurized feeding systems, which moves backward synchronously with the solder paste being dispensed into the syringes. In this automatic dispensing device, an air source pressurizes the dispensing container, and the solder paste in the container is dispensed into the syringes through the outlet. As the solder paste enters, it pushes a push rod backward synchronously, ensuring the solder paste enters the syringes at a uniform speed, guaranteeing the quality of solder paste dispensing. The device has a simple structure and can automate solder paste dispensing, improving efficiency. However, after filling, the top and bottom caps of the syringes still need to be manually tightened, wasting manpower and resulting in low production efficiency. Although some filling equipment has a capping mechanism, it usually adopts a rotary capping mechanism or a production line-type linear capping mechanism. Although it can achieve automatic capping, it occupies a large space and is costly.

[0003] Therefore, how to provide a small-sized and highly efficient integrated filling and capping equipment for paste products is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention aims to provide an integrated ointment filling and capping device to at least partially solve the problems of large space occupation and high cost of existing filling and capping devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A frame, wherein two capping positions are arranged at intervals along the X-axis and a filling position is located between the two capping positions;

[0007] A barrel clamping frame is reciprocally slidably mounted on the frame along the X-axis direction, and at least two sets of barrel clamping cavities are spaced apart along the X-axis direction. The barrel to be filled can be clamped in the barrel clamping cavity. The top of the barrel is open and a piston is slidably connected inside. The bottom of the barrel is provided with an injection port, and an injection cavity is formed between the injection port and the piston.

[0008] A filling mechanism is fixed on the frame at the filling position, and its discharge end can be connected to the injection port at the bottom of the material cylinder to inject paste into the injection chamber.

[0009] The sealing mechanism comprises two sets, each set of which is installed on the frame at two sealing positions. Each set of sealing mechanisms includes an upper sealing mechanism and a lower sealing mechanism. The upper sealing mechanism is installed on the frame above the material cylinder clamping frame to install an upper cover at the top opening of the material cylinder, and the lower sealing mechanism is installed on the frame below the material cylinder clamping frame to install a lower cover at the bottom filling port of the material cylinder.

[0010] The beneficial effects achievable by this utility model are as follows: The cylinder clamping frame can drive the cylinder to be filled to slide back and forth between the filling position and two capping positions for filling and capping operations. Specifically, after the cylinder to be filled on one cylinder tray slides to the filling position for filling, it can continue to slide to the capping position for capping using the capping mechanism. Then, it is unloaded and a new cylinder is loaded. At this time, the cylinder to be filled on the other cylinder tray moves to the filling position for filling. When the cylinder on the other cylinder tray is full, the cylinder tray moves in the opposite direction, allowing the new cylinder to be replaced to move to the filling position for filling. The full cylinder moves to the other capping position for capping and replacement with a new cylinder. Thus, by using the cylinder clamping frame to slide back and forth between the filling position and the two capping positions, continuous filling can be achieved without stopping the machine, improving production efficiency. Furthermore, it is small in size and saves costs.

[0011] Furthermore, the upper sealing mechanism includes:

[0012] The cover bin is fixed on the frame above the material cylinder clamping frame corresponding to the sealing position, and it has an upper cover placement hole arranged axially along the Z-axis; multiple upper covers are stacked in the upper cover placement hole and can slide along its axial direction;

[0013] The cap-pressing assembly includes a cap-pressing cylinder and a pneumatic suction cup. The cap-pressing cylinder is arranged at a distance from the cap chamber along the Y-axis and is installed on the frame corresponding to the capping position. Its piston rod is arranged along the Z-axis. The pneumatic suction cup is fixed to the bottom of the piston rod of the cap-pressing cylinder.

[0014] The cover-pushing assembly includes a cover-pushing cylinder and a cover tray. The cover-pushing cylinder is arranged along the Y-axis and fixed on the frame below the cover compartment at the corresponding sealing position. One end of the cover tray is fixed to the piston rod of the cover-pushing cylinder, and the other end is slidably connected along the Y-axis between the cover compartment and the pneumatic suction cup to receive the cover that slides down from the cover placement hole and transport it to the pneumatic suction cup for adsorption.

[0015] The beneficial effects that the previous technical solution can achieve are: the top cover is stored in the cover chamber and can slide down onto the top cover tray under the action of gravity; the push cylinder pushes out, pushing the top cover tray under the pneumatic suction cup and being attracted; the push cylinder retracts, and the top cover tray returns to the bottom of the cover chamber to receive the sliding top cover again; the press cylinder presses the top cover on the pneumatic suction cup to the open part of the top of the material cylinder.

[0016] Furthermore, the upper cover tray includes a push plate, a tray lifting assembly, and a tray. The push plate is slidably connected along the Y-axis to the frame below the cover compartment, and one end of the push plate is connected to the piston rod of the push cover cylinder. The tray lifting assembly is installed at the other end of the push plate. One end of the tray is connected to the lifting end of the tray lifting assembly, and the other end is open to form an upper cover inlet. The upper cover can enter the tray through the upper cover inlet.

[0017] The beneficial effects that the previous technical solution can achieve are as follows: Before the cap is pressed, the cap-pushing cylinder pushes the push plate, which moves the tray to the bottom of the pneumatic suction cup. At the same time, the tray is raised by the tray lifting component so that the cap contacts the pneumatic suction cup. After the pneumatic suction cup adsorbs the cap, the cap-pushing cylinder pulls the push plate back to its original position. During this process, the tray lifting component lowers the tray, and the tray returns to the bottom of the cap compartment to receive the sliding cap again.

[0018] Furthermore, the pallet lifting assembly includes a torsion spring, two sets of linkage assemblies, and two pressure rollers. A torsion spring mounting groove is provided at the end of the push plate away from the cover-pushing cylinder. A rotating shaft arranged along the X-axis is fixed within the torsion spring mounting groove. The torsion spring is sleeved on the rotating shaft, and its two ends are respectively connected to the push plate and the pallet. The two sets of linkage assemblies are symmetrically installed on both sides of the push plate along the X-axis, with one end of each linkage assembly hinged to the side wall of the push plate and the other end hinged to the side wall of the pallet. The two sets of pressure rollers correspond to and are rotatably mounted on the end wall of the cover compartment away from the cover-pushing cylinder, with their rolling surfaces rollingly connected to the upper surface of the linkage assemblies.

[0019] The beneficial effects that the previous technical solution can achieve are: when the push plate is pushed out, the tray rises under the action of the torsion spring and the connecting rod assembly; when the push plate is pulled back, the tray slowly descends under the pressure of the pressure roller.

[0020] Furthermore, the linkage assembly includes a first linkage and a second linkage arranged in parallel. The first linkage and the second linkage have the same length, and one end of each linkage is hinged to the side wall of the push plate, and the other end is hinged to the side wall of the tray. The rolling surface of the pressure roller is rolledly connected to the upper surface of the first linkage.

[0021] The beneficial effects that the previous technical solution can achieve are: the first link, the second link, the tray and the push plate together form a parallelogram linkage mechanism, which prevents the tray from flipping during lifting and lowering, and prevents the top cover from falling off.

[0022] Furthermore, the top of the push plate is provided with a limiting groove that extends through the end face away from the push cover cylinder, and the upper part of the end wall of the tray near the push plate is fixed with a limiting plate that is limited and connected to the limiting groove to limit the descent height of the tray.

[0023] The benefits of the previous technical solution include: enhancing the stability of the pallet and preventing it from falling too far and failing to return to the bottom of the cover.

[0024] Furthermore, the cap suction and cap pressing assembly also includes a cap pressing cylinder angle adjustment assembly, which includes an angle adjustment cylinder and a mounting plate. The mounting plate is arranged along the Z-axis and its middle part is connected to the frame above the cap compartment via a hinge. The angle adjustment cylinder is arranged along the Y-axis and its one end is hinged to the frame, and its other end is hinged to the upper end of the mounting plate. The cap pressing cylinder is fixed to the other plate of the mounting plate.

[0025] The beneficial effects that the previous technical solution can achieve are: the angle adjustment cylinder can drive the pressure cap cylinder to tilt, so that it moves away from or closer to the material cylinder clamping frame, making it convenient to take out or place the material cylinder.

[0026] Furthermore, the lower capping mechanism includes a lifting cylinder, a capping motor, and a lower cap gripper. The lifting cylinder is arranged along the Z-axis and installed on the frame at the capping position below the material cylinder clamping frame. The capping motor is installed on top of the lifting cylinder, and the lower cap gripper is fixed to the top of the output shaft of the capping motor.

[0027] The beneficial effects that the previous technical solution can achieve are: after the material cylinder is in place, the lifting cylinder drives the lower cover clamp to rise and connect with the injection port, and screws the lower cover onto the injection port.

[0028] Furthermore, the filling mechanism includes a lifting drive unit, a storage tank, a sealing plug, a discharge pipe, a nozzle lifting cylinder, a nozzle fixing frame, a nozzle, and a discharge valve. The lifting drive unit is installed on the lower part of the frame at the filling position. The storage tank is installed on the lifting end of the lifting drive unit with its top open. The top of the sealing plug is fixed to the frame by a support rod and is slidably installed in the inner cavity of the storage tank along the Z-axis direction. Its top has a discharge port communicating with the inner cavity of the storage tank. The inlet end of the discharge pipe is connected to the discharge port. The nozzle lifting cylinder is arranged along the Z-axis direction and fixed on the frame at the filling position. The nozzle fixing frame is fixed to the lifting end of the nozzle lifting cylinder. The nozzle is fixed on the nozzle fixing frame and communicates with the discharge end of the discharge pipe. The discharge valve is installed between the nozzle and the discharge pipe.

[0029] The beneficial effects of the previous technical solution are: the storage tank is placed in a low position, which facilitates material addition. The nozzle is connected to the material inlet of the cylinder under the drive of the nozzle lifting cylinder. The lifting drive unit drives the storage tank to rise, reducing the volume of the cavity between it and the sealing plug, squeezing the ointment through the outlet into the discharge pipe, and then squeezing it through the nozzle into the cylinder for filling.

[0030] As can be seen from the above technical solution, compared with the prior art, the present invention discloses an integrated ointment filling and capping device, which has the following beneficial effects:

[0031] 1. By setting capping mechanisms on both sides of the filling mechanism, the cylinder clamping frame can drive the cylinder to be filled to slide back and forth between the filling mechanism and the two capping mechanisms, so that continuous filling and capping can be carried out without stopping the machine, improving production efficiency. In addition, it is small in size and saves costs.

[0032] 2. The upper and lower sealing mechanisms can be used to install the upper and lower covers of the material cylinder simultaneously, improving production efficiency.

[0033] 3. The cap compartment can store multiple caps, reducing the frequency of cap replenishment and improving capping efficiency.

[0034] 4. The push-cover assembly can push the cover out while simultaneously rising and adsorbing it with the pneumatic suction cup, and retract it while simultaneously falling and detaching from the cover, thereby achieving synchronous operation of the cover's push-pull and lifting, reducing the action interval time and improving the cover pressing efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0058] Please see Figures 1-11 This utility model discloses an integrated ointment filling and capping device, including: a frame 1, a material cylinder clamping frame 2, a filling mechanism 3, and a capping mechanism.

[0059] The frame 1 is provided with two capping positions arranged at intervals along the X-axis and a filling position placed between the two capping positions; the bottom of the frame 1 is equipped with an adjustable height support leg, which includes a screw and a pad. The screw is threaded to the bottom of the frame 1, and the pad is fixed to the bottom of the screw. By adjusting the length of the screw, the height of the support leg can be adjusted so that the frame 1 can be placed stably on the ground.

[0060] The barrel clamping frame 2 is slidably mounted on the frame 1 along the X-axis, and has at least two sets of barrel clamping cavities spaced apart along the X-axis. The top of the barrel 6 is open and a piston is slidably connected inside. A filling port is provided at the bottom of the barrel, forming a filling cavity between the filling port and the piston. In some embodiments, the barrel clamping frame 2 includes a frame body and at least one gripper arranged along the X-axis. The frame body is slidably connected to a slide rail on the frame 1 along the X-axis, and the gripper is fixed to the frame body. The barrel clamping cavity is the clamping cavity of the gripper. In other embodiments, the barrel clamping cavity is a plurality of barrel placement holes spaced apart along the X-axis on the barrel clamping frame 2. The barrel 6 can be placed in the barrel placement holes for easy placement and removal. When the barrel clamping cavity is a barrel placement hole, a barrel pressure plate 7 should also be installed on the frame 1 above the barrel clamping frame 2 corresponding to the filling position. There is a sliding gap between the barrel pressure plate 7 and the barrel clamping frame 2 to press the barrel and prevent the barrel from moving during filling and causing leakage.

[0061] The filling mechanism 3 is fixed on the frame 1 of the filling position, and its discharge end can be connected to the injection port at the bottom of the material cylinder 6 to inject paste into the injection chamber;

[0062] The capping mechanism has two sets, each mounted on a frame 1 at a different capping position. Each set includes an upper capping mechanism 4 and a lower capping mechanism 5. The upper capping mechanism 4 is mounted on the frame 1 above the cylinder clamping frame 2 to install the upper cap onto the top opening of the cylinder 6, while the lower capping mechanism 5 is mounted on the frame 1 below the cylinder clamping frame 2 to install the lower cap onto the bottom filling port of the cylinder 6. As the cylinder clamping frame 2 slides back and forth alternately to the two sets of capping mechanisms, the capping operation is performed, reducing space occupation while improving filling and capping efficiency.

[0063] The upper sealing mechanism 4 includes a cover chamber 41, a cover pushing assembly 42, and a cover suction and pressing assembly 43;

[0064] The cover 41 is fixed on the frame 1 above the material cylinder clamping frame 2, corresponding to the sealing position, and has an upper cover placement hole 411 arranged axially along the Z-axis; multiple upper covers are stacked in the upper cover placement hole 411 and can slide along its axial direction under the action of gravity.

[0065] The cap-pressing assembly 43 includes a cap-pressing cylinder 431 and a pneumatic suction cup 432. The cap-pressing cylinder 431 is arranged at intervals with the cap chamber 41 along the Y-axis and is installed on the frame 1 corresponding to the capping position. Its piston rod is arranged along the Z-axis. The pneumatic suction cup 432 is fixed to the bottom of the piston rod of the cap-pressing cylinder 431.

[0066] The cover-pushing assembly 42 includes a cover-pushing cylinder 421 and an upper cover tray 422. The cover-pushing cylinder 421 is arranged along the Y-axis and fixed on the frame 1 below the cover chamber 41 corresponding to the sealing position. One end of the upper cover tray 422 is fixed to the piston rod of the cover-pushing cylinder 421, and the other end is slidably connected along the Y-axis to the cover chamber 41 and below the pneumatic suction cup 432 to receive the upper cover that slides down from the upper cover placement hole 411 and transport it to the pneumatic suction cup 432 for adsorption. The cover-pressing cylinder 431 can press the upper cover on the pneumatic suction cup 432 to the top opening of the material cylinder 6.

[0067] The top cover tray 422 includes a push plate 4221, a tray lifting assembly, and a tray 4222. The push plate 4221 is slidably connected to the frame below the corresponding cover compartment 41 along the Y-axis, and one end of it is connected to the piston rod of the push cover cylinder 421. The tray lifting assembly is installed at the other end of the push plate 4221. One end of the tray 4222 is connected to the lifting end of the tray lifting assembly, and the other end is open to form a top cover inlet. The top cover can enter the tray 4222 through the top cover inlet. Before capping, the cap-pushing cylinder 421 pushes the push plate 4221, which slides to below the cap chamber 41 to prevent the cap from falling out. The tray 4222 moves to below the pneumatic suction cup 432 and rises under the action of the tray 4222 lifting component, so that the cap contacts the pneumatic suction cup 432. After the pneumatic suction cup 432 adsorbs the cap, the cap-pushing cylinder 421 pulls the push plate 4221 back to its original position. During this process, the tray 4222 lifting component drives the tray 4222 to descend, and the tray 4222 returns to below the cap chamber 41 to catch the cap that has fallen out.

[0068] The pallet lifting assembly includes a torsion spring 4223, two sets of connecting rod assemblies 4224, and two pressure rollers 4225. A torsion spring mounting groove is provided at the end of the push plate 4221 away from the cover-pushing cylinder 421. A rotating shaft arranged along the X-axis is fixed in the torsion spring mounting groove. The torsion spring 4223 is sleeved on the rotating shaft and its two ends are respectively connected to the push plate 4221 and the pallet 4222. The two sets of connecting rod assemblies 4224 are symmetrically installed on both sides of the push plate 4221 along the X-axis. Each set of connecting rod assemblies 4224 is hinged at one end to the side wall of the push plate 4221 and at the other end to the side wall of the pallet 4222. The two sets of pressure rollers 4225 correspond to the two sets of connecting rod assemblies 4224 and are rotatably installed on the end wall of the cover chamber 41 away from the cover-pushing cylinder 421. Their rolling surfaces are in rolling contact with the upper surface of the connecting rod assemblies 4224. When the push plate 4221 is pushed out, the tray 4222 rises under the action of the torsion spring 4223 and the connecting rod assembly 4224. When the push plate 4221 is pulled back, the tray 4222 falls under the pressure of the pressure roller 4225.

[0069] The linkage assembly 4224 includes a first link and a second link arranged in parallel. The first link and the second link are of the same length, and one end of each is hinged to the side wall of the push plate 4221, while the other end is hinged to the side wall of the tray 4222. The rolling surface of the pressure roller 4225 is rolledly connected to the upper surface of the first link. The first link, the second link, the push plate 4221, and the tray 4222 constitute a parallelogram linkage mechanism, preventing the tray 4222 from tipping over during lifting and lowering.

[0070] The top of the push plate 4221 is provided with a limiting groove 42211 that passes through the end face away from the push cover cylinder 421. The upper part of the end wall of the tray 4222 near the push plate 4221 is fixed with a limiting plate 42221 that is limited and connected to the limiting groove 42211. When the limiting plate 42221 abuts against the limiting groove 42211, the tray 4222 will no longer lower, preventing the tray 4222 from failing to return to the bottom of the cover chamber 41 and enhancing the stability of the tray 4222.

[0071] The capping assembly 43 also includes a capping cylinder angle adjustment assembly, which includes an angle adjustment cylinder 433 and a mounting plate 434. The mounting plate 434 is arranged along the Z-axis, and one of its surfaces is connected to the frame 1 above the capping compartment 41 via a hinge 435. The angle adjustment cylinder 433 is arranged along the Y-axis, with one end hinged to the frame 1 and the other end hinged to the upper part of the mounting plate 434. The capping cylinder 431 is fixed to the other surface of the mounting plate 434. The angle adjustment cylinder 433 can tilt the capping cylinder 431, moving it away from or closer to the material cylinder 6 mounting frame, facilitating the removal or placement of the material cylinder 6.

[0072] The lower capping mechanism 5 includes a lifting cylinder 51, a capping motor 52, and a lower cap gripper 53. The lifting cylinder 51 is arranged along the Z-axis and installed on the frame 1 below the capping position of the material cylinder clamping frame 2. The capping motor 52 is installed on top of the lifting cylinder 51, and the lower cap gripper 53 is fixed to the top of the output shaft of the capping motor 52. After the material cylinder 6 is in position, the lifting cylinder 51 drives the lower cap gripper 53 to rise and connect with the injection port, screwing the lower cap onto the injection port.

[0073] The filling mechanism 3 includes a lifting drive unit 31, a storage tank 32, a sealing plug 33, a discharge pipe 34, a nozzle lifting cylinder, a nozzle fixing bracket 35, a nozzle 36, and a discharge valve 37. The lifting drive unit 31 is installed at the lower part of the frame 1 at the filling position. The storage tank 32 is installed at the lifting end of the lifting drive unit 31 with its top open. The top of the sealing plug 33 is fixed to the frame 1 by a support rod, and it is slidably installed in the inner cavity of the storage tank 32 along the Z-axis direction. Its top has a discharge port communicating with the inner cavity of the storage tank 32. The inlet end of the discharge pipe 34 is connected to the discharge port. The nozzle lifting cylinder is arranged along the Z-axis direction and fixed to the frame 1 at the filling position. The nozzle fixing bracket 35 is fixed to the lifting end of the nozzle lifting cylinder. The nozzle 36 is fixed to the nozzle fixing bracket 35 and communicates with the discharge end of the discharge pipe 34. The discharge valve 37 is installed between the nozzle 36 and the discharge pipe 34. The storage tank 32 is placed in a low position for easy filling. The nozzle 36 is connected to the filling port of the material cylinder 6 under the drive of the nozzle lifting cylinder. The lifting drive unit 31 drives the storage tank 32 to rise, reducing the volume between it and the sealing plug 33, squeezing the ointment into the discharge pipe 34 through the discharge port, and then squeezing it into the material cylinder 6 through the nozzle 36 for filling.

[0074] The lifting drive unit 31 includes a drive motor 311, two sprocket transmission units 312, two lead screws 313, and a holding cylinder 314. The drive motor 311 is fixed to the lower part of the frame 1. The input ends of the two sprocket transmission units 312 are connected to the output ends of the drive motor 311. The two lead screws 313 are arranged side by side and rotatably connected to the lower part of the frame 1, respectively connecting to the output ends of the two sprocket transmission units 312. Each lead screw 313 has a threaded hole 3141 on both sides of the holding cylinder 314 for transmission with the lead screw 313. The storage bin 32 is held inside the holding cylinder 314. The drive motor 311 drives the two lead screws 313 to rotate through the two sets of sprocket transmission units, thereby driving the holding cylinder 314 to lift and lower, thus pushing the storage bin 32 to lift and lower.

[0075] How to use:

[0076] When filling, see Figure 1The material cylinder clamping frame 2 slides to the left to move the material cylinder 6 to the filling position. The lifting drive unit 31 drives the storage tank 32 to rise and squeeze the ointment into the discharge pipe 34. The nozzle lifting cylinder drives the manifold to rise to the nozzle 36 and connect with the bottom injection port of the material cylinder 6 to inject the ointment into the material cylinder 6. The discharge valve 37 is opened and the ointment enters the injection chamber. After filling, the nozzle 36 returns to the initial position and the filling is completed.

[0077] After filling is completed, the cartridge holder 2 continues to slide to the left, moving the filled cartridge 6 to correspond with the capping mechanism on the left. The empty cartridge 6 on the right moves to the filling position, and the filling mechanism fills the empty cartridge 6 on the right. At the same time, the cap-pushing cylinder 421 pushes the push plate 4221 forward, moving the tray 4222 above the filled cartridge 6 on the left. The pneumatic suction cup 432 adheres to the top cover, and then the cap-pushing cylinder 421 retracts, and the tray 4222 moves back to below the cap chamber 41, placing the top cover. The top cover at the bottom of hole 411 falls back into the top cover inlet of tray 4222; the capping cylinder 431 drives the pneumatic suction cup 432 to descend, pressing the top cover onto the top of the material cylinder 6. At the same time as the capping cylinder 431 presses the top cover, the lifting cylinder 51 drives the lower cover clamp 53 to rise and screws the lower cover onto the bottom filling port of the material cylinder 6. The lifting cylinder 51 drives the lower cover clamp 53 to descend to the initial position, and the capping cylinder 431 also drives the pneumatic suction cup 432 to rise to the initial position, completing the capping.

[0078] After the capping is completed, the angle adjustment cylinder 433 drives the mounting plate 434 to rotate away from the material cylinder clamping frame 2, removes the capped material cylinder 6, and puts in a new material cylinder 6; after the new material cylinder 6 is placed and the empty material cylinder 6 on the right is filled, the material cylinder clamping frame 2 slides to the right, so that the new material cylinder 6 on the left moves to the filling position again for filling, and the filled material cylinder 6 on the right moves to the capping position on the right for capping. The operation of replacing the capped material cylinder 6 with a new material cylinder 6 is repeated. The above steps can be repeated to continuously perform filling and capping operations, thereby improving production efficiency.
