Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil production equipment, and in particular to a packaging device for lubricating oil production. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and machinery to reduce friction and protect the machinery and processed parts. Its main functions include lubrication, auxiliary cooling, rust prevention, cleaning, sealing, and buffering. Any substance that reduces friction and wear between two relatively moving objects is considered lubricating oil. After production, lubricating oil needs to be bottled and sealed (i.e., capped) for subsequent sale.

[0003] In existing technologies, due to the large number of lubricating oil bottles, automated packaging equipment is usually used for capping. Before capping, some equipment places the caps on the lubricating oil bottles, but the caps are not tightened at this time. Then, a conveyor belt is used to transport the lubricating oil bottles with the caps on them one by one to the bottom of the capping mechanism. The capping head of the capping mechanism presses down on the caps, and then the caps are rotated and tightened. There is a problem with this method: when the lubricating oil bottles are transported to the bottom of the capping head, they often cannot be properly aligned with the capping head. That is, the two are easily misaligned in the horizontal direction, which leads to errors during capping and affects the packaging quality. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a packaging device for lubricating oil production, which can accurately position the lubricating oil bottle and achieve high-quality sealing when capping the bottle.

[0010] The clamping assembly includes two clamping blocks and a driving assembly. The two clamping blocks are symmetrically distributed front and back relative to the capping head. Each clamping block has two clamping planes on its opposite side. The two clamping planes of the same clamping block are arranged at an angle and are symmetrically distributed left and right. The driving assembly is connected to the two clamping blocks and is used to drive the two clamping blocks to move synchronously towards each other or away from each other in the front-back direction to clamp or release the lubricating oil bottle.

[0011] The packaging equipment for lubricating oil production according to the embodiments of this utility model has at least the following beneficial effects:

[0012] By setting two clamping blocks symmetrically distributed relative to the capping head, and setting two symmetrically distributed clamping planes on the opposite sides of the two clamping blocks, when the lubricating oil bottle is transferred to the lower side of the capping head, the two clamping blocks can be ordered to move synchronously towards each other, thereby pushing the lubricating oil bottle to move and vertically align with the capping head, achieving precise horizontal positioning of the lubricating oil bottle. This allows the subsequent capping head to accurately press on the cap of the lubricating oil bottle and drive the cap to rotate, resulting in high sealing quality.

[0018] Two nut seats are respectively connected to two clamping blocks, and the two nut seats are respectively threaded into the first shaft segment and the second shaft segment;

[0019] The packaging equipment for producing lubricating oil also includes a guide structure for guiding the back-and-forth movement of the two clamping blocks.

[0020] According to some embodiments of the present invention, the driving component and the guiding structure are both disposed on the lifting frame so that the clamping block can rise and fall synchronously with the lifting frame.

[0021] According to some embodiments of the present invention, an elastic buffer structure is provided between the output end of the rotary drive unit and the sealing head, so that the sealing head can move vertically elastically relative to the rotary drive unit.

[0022] According to some embodiments of the present invention, the elastic buffer structure includes:

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0048] In existing technologies, due to the large number of lubricating oil bottles, automated packaging equipment is usually used for capping. Before capping, a corresponding device places the cap on the lubricating oil bottle, but the cap is not tightened at this time. Then, a conveyor belt is used to transport the lubricating oil bottles with the caps on them one by one to the bottom of the capping mechanism. The capping head of the capping mechanism presses down on the cap, and then the cap is rotated and tightened. There is a problem with this method, that is, when the lubricating oil bottle is transported to the bottom of the capping head, it is often not well aligned with the capping head (vertical alignment). That is, the lubricating oil bottle and the capping head are easily misaligned in the horizontal direction, which leads to errors in capping and affects the packaging quality.

[0049] Therefore, this utility model proposes a packaging device for lubricating oil production, which can effectively improve the above-mentioned problems.

[0050] The packaging equipment for producing lubricating oil according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0051] Reference Figures 1 to 4 As shown, an embodiment of the lubricating oil production packaging equipment of this utility model includes: a frame 100, a conveyor belt 200, a lifting frame 400, a capping assembly 500, and a clamping assembly 600. It should be noted that the lubricating oil production packaging equipment of this utility model is applied to a cylindrical lubricating oil bottle 300, and when packaging using the equipment of this embodiment, a bottle cap 310 is already placed on the lubricating oil bottle 300.

[0052] The conveyor belt 200 is mounted on the frame 100 and is used to transport the lubricating oil bottle 300 in the left and right directions. It should be noted that the conveyor belt 200 is equipped with supporting rollers and a power structure, which are conventional technical means and will not be described in detail here.

[0053] The lifting frame 400 is positioned above the conveyor belt 200. Specifically, the frame 100 is equipped with a lifting drive unit 410, which is connected to the lifting frame 400 and is used to drive the lifting frame 400 to lift. The lifting drive unit 410 can be one of a telescopic cylinder, a telescopic hydraulic cylinder, or a telescopic motor.

[0054] The capping assembly 500 includes a rotary drive unit 510 and a capping head 520. The rotary drive unit 510 is connected to the lifting frame 400 and can be raised and lowered synchronously with the lifting frame 400. The capping head 520 is connected to the output end of the rotary drive unit 510 and can rotate around a vertically distributed axis under the drive of the rotary drive unit 510. The capping head 520 is used to contact the bottle cap 310. It is conceivable that the rotary drive unit 510 can be one of a rotary cylinder, a rotary hydraulic cylinder, or a rotary motor.

[0055] The clamping assembly 600 includes two clamping blocks 610 and a drive assembly. The two clamping blocks 610 are symmetrically distributed in front and behind relative to the capping head 520. Each clamping block 610 has two clamping planes 611 on the opposite side. The two clamping planes 611 of the same clamping block 610 are set at an angle and are symmetrically distributed in the left and right directions. The clamping planes 611 are parallel to the vertical direction and are used to contact the outer wall of the lubricating oil bottle 300. The drive assembly is connected to the two clamping blocks 610 for driving the two clamping blocks 610 to move synchronously in front or behind each other in the front and back direction to clamp or release the lubricating oil bottle 300.

[0056] In this embodiment of the lubricating oil production packaging equipment, during use, the lifting frame 400 can first be adjusted to a position that does not obstruct the left and right transmission of the lubricating oil bottle 300. Then, the conveyor belt 200 transmits the lubricating oil bottle 300 to the lower side of the capping head 520. Then, the drive assembly drives the two clamping blocks 610 to move synchronously towards each other. During the synchronous movement of the two clamping blocks 610 towards each other, the clamping plane 611 on the clamping blocks 610 contacts the outer wall of the lubricating oil bottle 300, thus... The lubricating oil bottle 300 is moved horizontally to align it vertically with the capping head 520, thus centering the lubricating oil bottle 300 and the capping head 520. Then, the lifting frame 400 is lowered so that the capping head 520 presses onto the bottle cap 310 of the lubricating oil bottle 300. The rotary drive unit 510 then drives the capping head 520 to rotate, thereby using the friction between the capping head 520 and the bottle cap 310 to rotate the bottle cap 310, and then tightening the bottle cap 310 to complete the sealing.

[0057] The lubricating oil production packaging equipment of this embodiment uses two clamping blocks 610, which are symmetrically distributed in front and behind relative to the capping head 520. Two clamping planes 611 are symmetrically distributed on the opposite sides of the two clamping blocks 610. When the lubricating oil bottle 300 is transferred to the lower side of the capping head 520, the two clamping blocks 610 can be ordered to move synchronously towards each other, thereby pushing the lubricating oil bottle 300 to move and vertically align with the capping head 520. This achieves precise horizontal positioning of the lubricating oil bottle 300, so that the capping head 520 can accurately press on the cap 310 of the lubricating oil bottle 300 and drive the cap 310 to rotate, resulting in high packaging quality.

[0058] It should be noted that when clamping block 610 clamps lubricating oil bottle 300, it should be positioned in the lower middle part of the height direction of lubricating oil bottle 300 to avoid tipping over lubricating oil bottle 300.

[0059] Reference Figure 2 and Figure 4As shown, in some embodiments of this utility model, the two clamping planes 611 of the same clamping block 610 are set at an obtuse angle. The advantage of the obtuse angle is that for some lubricating oil bottles 300 with larger diameters, the clamping planes 611 do not need to be designed to be very large, and can still abut against the outer wall of the lubricating oil bottle 300.

[0060] Reference Figure 3 As shown, in some embodiments of this utility model, the bottom of the capping head 520 has a downward-facing recessed cavity 521. The recessed cavity 521 is a cylindrical cavity that is adapted to the cap 310 of the lubricating oil bottle 300 and is used for the cap 310 to be inserted. Thus, the recessed cavity 521 can play a certain limiting role in the cap 310, improving the sealing accuracy. It should be noted that during the process of the clamping block 610 clamping the lubricating oil bottle 300, the recessed cavity 521 needs to be positioned above the cap 310. After the lubricating oil bottle 300 is positioned, the lifting frame 400 is lowered to allow the cap 310 to be inserted into the recessed cavity 521.

[0061] Reference Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the driving assembly includes a driving screw 620, a clamping driving part 630, and two nut seats 640. The driving screw 620 is distributed front to back and can rotate around its own axis. The driving screw 620 includes a first shaft segment 621 and a second shaft segment 622 distributed sequentially along its length direction, with the threads of the first shaft segment 621 and the second shaft segment 622 having opposite directions. The clamping driving part 630 is connected to the driving screw 620 and is used to drive the driving screw 620 to rotate. The two nut seats 640 are respectively connected to two clamping blocks 610, and the two nut seats 640 are threadedly engaged with the first shaft segment 621 and the second shaft segment 622, respectively. The packaging equipment for lubricating oil production also includes a guide structure, which is used to guide the front-back movement of the two clamping blocks 610. Thus, by rotating the driving screw 620, the two nut seats 640 can be driven to move synchronously towards each other or away from each other in the front-back direction, thereby realizing the clamping or release of the lubricating oil bottle 300.

[0062] With the above structure, the movement of the two clamping blocks 610 can be precisely controlled, the positioning accuracy of the lubricating oil bottle 300 is high, and only one power component (i.e., clamping drive unit 630) is set to drive the drive screw 620 to rotate, so that the two clamping blocks 610 can move synchronously towards each other or away from each other. The structure is simple and easy to control.

[0063] It is conceivable that the clamping drive unit 630 can be one of a rotary motor, a rotary cylinder, or a rotary hydraulic cylinder.

[0064] It is conceivable that, such as Figure 4As shown, the guide structure may include a guide rod 700 and two guide sleeves 710. The guide rod 700 is arranged front to back, and the two guide sleeves 710 are respectively connected to two clamping blocks 610 and slide in cooperation with the guide rod 700 to provide guidance for the front to back movement of the clamping blocks 610.

[0065] It is conceivable that the drive assembly and guide structure can both be directly connected to the frame 100, meaning their height relative to the frame 100 remains constant. For example, the drive screw 620 can be rotatably mounted on the frame 100, and the guide rod 700 can be fixed to the frame 100. As long as the height of the drive screw 620 and the guide rod 700 is higher than that of the lubricating oil bottle 300, it will not interfere with the lateral transmission of the lubricating oil bottle 300. Of course, other structural forms are also possible.

[0066] For example, in some embodiments of this utility model, reference is made to Figure 2 and Figure 4 As shown, the drive assembly and guide structure are both located on the lifting frame 400 so that the clamping block 610 can rise and fall synchronously with the lifting frame 400. The advantage of this arrangement is that the vertical dimension of the clamping block 610 does not need to be very large. When it is necessary to transfer the lubricating oil bottle 300 left and right, the lifting frame 400 can be raised to a position where the components will not obstruct the transfer of the lubricating oil bottle 300. When it is necessary to clamp the lubricating oil bottle 300, the lifting frame 400 can be lowered to a position where the lubricating oil bottle 300 is located between the two clamping blocks 610.

[0067] In some specific embodiments, the drive screw 620 is rotatably mounted on the lifting frame 400, and the guide rod 700 is fixed on the lifting frame 400.

[0068] Reference Figures 2 to 4 As shown, in some embodiments of this utility model, an elastic buffer structure is provided between the output end of the rotary drive unit 510 and the capping head 520, so that the capping head 520 can move vertically elastically relative to the rotary drive unit 510, thereby providing a certain elastic buffer when the capping head 520 presses against the bottle cap 310, avoiding excessive pressure that could damage the threads of the mating part between the bottle cap 310 and the lubricating oil bottle 300.

[0069] Reference Figure 3 and Figure 4As shown, in some embodiments of this utility model, the elastic buffer structure includes: a mounting base 530, a sliding base 540, and an elastic part 550. The mounting base 530 is connected to the output end of the rotary drive unit 510 and can rotate under the drive of the rotary drive unit; the sliding base 540 is vertically slidably mounted on the mounting base 530. Obviously, the sliding base 540 can rotate synchronously with the mounting base 530 and can slide vertically relative to the mounting base 530; the elastic part 550 is disposed between the mounting base 530 and the sliding base 540 and is used to apply a downward elastic force to the sliding base 540; the capping head 520 is disposed at the bottom of the sliding base 540; thus, when the capping head 520 presses against the bottle cap 310, a certain elastic buffer can be provided by the elastic part 550, which is simple and practical.

[0070] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the sliding seat 540 is provided with a vertically extending slide rod 541. The slide rod 541 slides vertically through the mounting seat 530 and is connected to a detachable limiting structure on the upper side of the mounting seat 530. The elastic part 550 is configured as a compression spring and is sleeved on the slide rod 541. The upper and lower ends of the compression spring abut against the mounting seat 530 and the sliding seat 540 respectively. In this way, the compression spring provides downward elastic pressure, and the slide rod 541 provides guidance for the vertical movement of the sliding seat 540 and provides installation position and deformation guidance for the compression spring. The structure is simple and practical. In addition, by providing a detachable limiting structure, the sliding seat 540 and the compression spring can be easily disassembled and assembled.

[0071] It is conceivable that the limiting structure can adopt a cylindrical pin, cotter pin, or other types of structure.

[0072] For example, in some embodiments of this utility model, reference is made to Figure 3 As shown, the limiting structure includes a limiting nut 542, which is threaded to the slide rod 541. The structure is simple and easy to disassemble and assemble, which helps to replace the pressure spring when it is worn out.

[0073] Reference Figure 4 As shown, in some embodiments of this utility model, multiple slide rods 541 are provided, and the multiple slide rods 541 are evenly spaced around the circumference. The elastic part 550 corresponds to each slide rod 541. This arrangement allows the sealing head 520 to move more smoothly in the vertical direction, avoiding jamming problems.

[0074] The method of using the packaging equipment for lubricating oil production according to one specific embodiment of this utility model is as follows:

[0075] In use, the lifting drive unit 410 first drives the lifting frame 400 upward to a position where all components avoid the transmission path of the lubricating oil bottle 300. Then, the conveyor belt 200 transports the lubricating oil bottle 300 to be sealed to the lower side of the capping head 520. Next, the lifting frame 400 is lowered so that the lubricating oil bottle 300 is positioned between the two clamping blocks 610, and the capping head 520 is slightly higher than the bottle cap 310 of the lubricating oil bottle 300. Then, the clamping drive unit 630 drives the drive screw 620 to rotate, causing the two clamping blocks 610 to move towards each other, thereby pushing the lubricating oil bottle 300 to move until the two clamping blocks 610 clamp the lubricating oil bottle 300, completing the connection between the lubricating oil bottle 300 and the capping head 520. The alignment is completed by first aligning the 0, then reversing the drive screw 620 by a small angle to reduce the friction between the clamping block 610 and the lubricating oil bottle 300. Then, the lifting frame 400 is lowered again so that the bottle cap 310 is embedded in the cavity 521 of the capping head 520 and pressed tightly against the top wall of the cavity 521. Then, the two clamping blocks 610 are controlled to move towards each other to clamp the lubricating oil bottle 300. Then, the capping head 520 is driven to rotate by the rotation drive unit 510 to tighten the bottle cap 310, completing the sealing. After sealing, the two clamping blocks 610 are released from the lubricating oil bottle 300, and then the lifting frame 400 is raised so that all components avoid the transmission path of the lubricating oil bottle 300, waiting for the sealing of the next lubricating oil bottle 300.
