Description

Technical Field

[0001] The utility model belongs to the technical field of filling equipment, in particular to a lubricating oil keg filling machine. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to perform functions such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Usually, lubricating oil is composed of base oil and additives. After the existing lubricating oil is processed, it is filled by a filling device to complete the sub-packaging. During the sub-packaging process, a transmission device is used to transfer the canned container. Due to the vibration of the transmission device, the filling container of the lubricating oil is often easily overturned during the transmission process, affecting the overall lubricating oil filling work.

[0003] In the prior art, patent 2023221215173 discloses a lubricating oil filling and dispensing device, which includes a transmission box, a through slot opened at the front end of the transmission box, a power box fixedly installed in the through slot, pulleys arranged on both sides of the rear end of the power box and a conveyor belt sleeved on the outside of the two pulleys, and the inner side walls on the front and rear sides above the transmission box are each fixedly connected with a group of mounting shafts, and a limiting frame is arranged just above the middle of the conveyor belt, each group of the mounting shafts is arranged in a rectangular array shape of two rows and multiple columns, and a guide wheel is rotatably installed on the outer side wall of each mounting shaft, and the front and rear ends of the upper and lower side walls of the limiting frame are each slidably connected with the guide wheel on the corresponding side, and the filling bottle can be limited by arranging a limiting frame above the filling bottle conveyor belt, and the limiting frame is slidably arranged between the two groups of guide wheel structures, and can move with the filling bottle, and at the same time, it can prevent the filling bottle slidably installed in the rubber sleeve of its limiting groove from overturning during transmission.

[0004] However, the above equipment still has the following problems in actual use:

[0005] Although the limit frame of the device can limit and fix the cans on the conveyor belt, the structure is simple and cannot limit and fix cans of various styles. In addition, the quantitative discharge device of the device is a fixed discharge port, which cannot be adjusted according to the specifications of the cans. In addition, the splashing of lubricating oil during the filling process may mix with air to produce bubbles, thereby affecting the quality of the lubricating oil. Utility Model Content

[0006] The purpose of the utility model is to provide a lubricating oil keg filling machine which can limit and protect canned containers of different sizes during the filling process.

[0007] The lubricating oil keg filling machine comprises a belt conveyor arranged transversely and used to transport canned containers, and two sets of intermediate guardrails are arranged in parallel and spaced apart from each other above the conveyor belt of the conveyor;

[0008] The left and right ends of the two sets of middle guardrails are hinged together by hinges. As the hinges are opened, the distance between the two sets of middle guardrails gradually increases.

[0009] Two sets of mounting brackets with inverted "U"-shaped structures are arranged on the conveyor, and the vertical parts on both sides of the mounting brackets are respectively installed on the conveyor, and the horizontal parts on the top of the mounting brackets are provided with first sliding holes for sliding left and right, and the first sliding holes are penetrated with first limiting rods sliding therein, and the first limiting rods are connected to the rotating shaft at the top of the corresponding hinge, and two second sliding holes for sliding forward and backward are arranged on the mounting brackets near the middle guardrail on both sides of the first sliding holes, and each second sliding hole is penetrated with a second limiting rod sliding therein, and the second limiting rods are respectively fixed to the corresponding leaf pieces of the hinge;

[0010] Side guardrails parallel to the two sets of middle guardrails are fixed on the conveyors outside them respectively. Two filling areas are arranged between the front middle guardrail and the front side guardrail and between the rear middle guardrail and the rear side guardrail. Filling mechanisms for injecting oil into canned containers are arranged above the two filling areas.

[0011] The second limiting rod in the second sliding hole on the rear side of each set of mounting brackets is fixed to the rear page of the hinge, and the second limiting rod in the second sliding hole on the front side is fixed to the front page of the hinge. The hinge shaft slides along the length direction of the conveyor belt in the first sliding hole along with the first limiting rod, driving the second limiting rod to slide back and forth in the second sliding hole, controlling the opening and closing degree of the hinge pages, and then adjusting the distance between the middle guardrail and the side guardrail, so as to limit and protect canned containers of different sizes; the first limiting rod slides in the first sliding hole, and then drives the second limiting rod to slide in the second sliding hole, so as to guide the two pages of the hinge when opening and closing and increase the stability of the hinge.

[0012] Furthermore, a cylinder is connected to the top of the first limiting rod to drive it to slide left and right in the first sliding hole, and the cylinder is installed on the mounting bracket.

[0013] The first limit rod is specifically connected to the piston rod of the cylinder. The cylinder drives the first limit rod to slide left and right in the first sliding hole, thereby controlling the opening and closing degree of the hinge, thereby controlling the relative distance between the middle guardrail and the side guardrail, and clamping canned containers of different sizes. It is suitable for the protection and fixation of canned containers of different sizes during the transportation and filling process. The cylinder drives the first limit rod to slide in the first sliding hole, saving time and effort.

[0014] Furthermore, the filling mechanism includes a fixed frame, on which is mounted a lifting assembly capable of adjusting the lifting of the fixed frame, and inside the fixed frame is mounted a filling head for injecting oil into the canned container, and the filling head can move laterally and longitudinally inside the fixed frame.

[0015] The injection ports of canned containers of different specifications are located at different positions in the filling area. The lifting assembly can adjust the lifting of the fixed frame, and then adjust the height between the filling head installed inside the fixed frame and the conveyor belt. The filling head moves in the horizontal and vertical directions in the fixed frame and is fixed at the appropriate position of the required injection port. The filling mechanism with adjustable positions in the front, back, left, right, and up and down directions can fill canned containers of various specifications.

[0016] Furthermore, the fixed frame includes an outer frame body, in which an inner frame body is installed in sliding cooperation therewith, and a filling head is slidably installed in the inner frame body, and a sliding direction of the filling head relative to the inner frame body and a sliding direction of the inner frame body relative to the outer frame body are perpendicular to each other.

[0017] Specifically, a slide rail is arranged in the inner frame, a slider slidably matched with the slide rail is arranged on the filling head, and after the filling head slides to the desired position, the filling head is fixed to the inner frame by bolts or buckles; a slide groove is arranged inside the outer frame, and the inner frame placed in the slide groove is slidably matched with the outer frame, and after the inner frame slides to the desired position along the outer frame, the inner frame and the outer frame are fixed by bolts or buckles; by arranging the sliding direction of the filling head relative to the inner frame and the sliding direction of the inner frame relative to the outer frame to be perpendicular to each other, the filling head can be driven to move in the length direction and the width direction of the conveyor belt respectively, thereby adjusting the position of the filling head above the conveyor belt, and realizing oil filling of canned containers with different injection port positions.

[0018] Furthermore, an oil suction pipe for negative pressure adsorption is provided at the oil outlet of the filling head, and a negative pressure adsorption end of the oil suction pipe is connected to a negative pressure pump.

[0019] After the oil filling is completed, start the negative pressure pump to absorb the unflowing lubricating oil on the filling head through the oil suction pipe, to prevent the unflowing lubricating oil from gathering at the oil outlet end of the filling head and dripping onto the conveyor belt, affecting the anti-slip property of the conveyor belt, etc. It can also prevent the residual oil from dripping to other places in the canned container, thereby affecting subsequent work.

[0020] Furthermore, the lifting assembly is a scissors-type lift, and an installation cabinet is provided on either side of the conveyor in the front and rear directions. The scissors-type lift is installed on the side of the installation cabinet close to the conveyor. The bottom of the scissors-type lift is connected to a shell, and the bottom of the shell is fixed to the fixed frame.

[0021] The scissor-type lift drives the fixed frame to rise and fall, and then the height of the filling head above the conveyor belt can be adjusted, so that the oil can be injected into the wall of the canned container at different heights and flow down, preventing the splashing of lubricating oil during the filling process and possible mixing with the air to produce bubbles, thereby adapting to canned containers of different heights. The installation cabinet can be used to fix the scissor-type lift, and can also be used to place negative pressure pumps and other equipment, so that the filling machine can achieve centralized management of equipment, and use and maintenance are more efficient.

[0022] Furthermore, the two second sliding holes are vertically arranged on both sides of the sliding direction of the first sliding hole, and are axially symmetrical with respect to the first sliding hole.

[0023] The two second sliding holes arranged vertically and symmetrically in the front and back direction of the sliding direction of the first sliding hole can ensure the hinge to be opened and closed, and can also ensure the stability of the hinge.

[0024] Furthermore, the middle guardrail and the side guardrails are made of alloy or plastic.

[0025] According to the size, dimensions and material of the filling container, different materials of middle guardrails and side guardrails can be selected to ensure the protective effect while choosing lower cost materials to reduce production costs.

[0026] Compared with the prior art, the utility model has the following beneficial effects:

[0027] 1. The filling head moves along the conveyor belt in both the horizontal and vertical directions to adapt to canned containers of various specifications with different injection port positions; the hinge shaft slides along the length direction of the conveyor belt through the first sliding hole to control the degree of opening and closing of the hinge, thereby adjusting the distance between the middle guardrail and the side guardrail, and canned containers of different sizes can be limited and protected.

[0028] 2. The cylinder drives the first limit rod to slide in the first sliding hole, thereby controlling the opening and closing degree of the hinge, thereby controlling the relative distance between the middle guardrail and the side guardrail, and clamping canned containers of different sizes. It is suitable for the protection and fixation of canned containers of different sizes during transportation and filling. The cylinder drives the first limit rod to slide in the first sliding hole, saving time and effort.

[0029] 3. After the oil filling is completed, start the negative pressure pump to absorb the unflowing lubricating oil on the filling head through the oil suction pipe to prevent the unflowing lubricating oil from gathering at the oil outlet end of the filling head and dripping onto the conveyor belt, affecting the anti-slip property of the conveyor belt, etc. It can also prevent the residual oil from dripping to other places in the canned container, thereby affecting subsequent work.

[0030] 4. Adjust the height of the filling head above the conveyor belt to achieve oil filling and flow down from the wall of canned containers of different heights, to prevent the splashing of lubricating oil during the filling process, which may be mixed with air to produce bubbles and affect the quality of the lubricating oil, so as to adapt to canned containers of different heights.

[0051] The above materials are assembled as follows:

[0052] Step 1: Processing

[0053] like Figure 7 As shown, two mounting brackets 2 are processed. Specifically, the metal plates can be divided into blocks and welded into an inverted "U"-shaped structure according to the use requirements to make the mounting bracket 2; Figure 3 As shown, a transverse waist-shaped hole is opened at the center of the horizontal part of the top of each mounting bracket 2 along the width direction of the conveyor belt as the first sliding hole 16; two waist-shaped holes are opened at the top of each mounting bracket 2, which are symmetrical and perpendicular to the front and rear axes with the horizontal center line of the first sliding hole 16 as the reference, as the second sliding holes 17. The second sliding holes 17 are opened on the side of the first sliding hole 16 close to the middle guardrail 4.

[0054] like Figure 1 , Figure 2 and Figure 7 As shown, the square housing 8 is made of metal plate by welding or stamping.

[0055] like Figure 6 and Figure 7As shown, two hinges 13 are processed. First, the metal plate is cut into four pieces of suitable size. One end of the four metal plates is stamped and rolled to form a sleeve to form a leaf. Every two leaves are made into a hinge. The sleeves of the two leaves are staggered. A metal shaft is inserted into the sleeve from the bottom of the sleeve to hinge the two metal plates to form a hinge 13. The manufacture of the hinge 13 can refer to the existing hinge manufacturing technology; the top surfaces of the leaves of the two hinges are provided with threaded holes at positions corresponding to the second sliding holes 17 for installing the second limiting rod 15, and a threaded hole is provided at the end of the metal shaft away from the head for installing the first limiting rod 14.

[0056] like Figure 1 and Figure 6 As shown, a metal square tube is welded to make an outer frame and three inner frames to form a fixed frame 7. A slide groove is provided on the inner side of the outer frame in the front-back direction. The inner frame is placed in the slide groove of the outer frame and can slide along the slide groove. Bolts are installed at the corresponding placement position of the inner frame to fix the inner frame. The inner frame is used to install the filling head 5. Specifically, a slide rail is provided inside the inner frame, and a slider that slides with the slide rail is provided on the filling head 5. The filling head 5 is fixed to the inner frame by bolts or buckles. The number of inner frames depends on the number of filling heads 5 actually required. One or more filling heads 5 can be installed in one inner frame.

[0057] Quick-release connectors are installed at both ends of the PU hose to form an oil suction pipe 6.

[0058] Step 2: Assembly

[0059] like Figure 1 As shown, the conveyor 1 is placed horizontally, and the conveyor belt of the conveyor 1 can transport canned containers horizontally. Two mounting brackets 2 are installed on the protective brackets on the front and rear sides of the conveyor 1. In actual use, the mounting brackets can also be fixed on the ground through the tripod. The two mounting brackets 2 are symmetrical. Figure 5 As shown, the first limiting rods 14 on both sides pass through the first sliding holes 16 and are connected to the metal shaft threaded holes of the corresponding hinges 13, so that the hinges and the first sliding holes 16 are slidably matched left and right, and each second limiting rod 15 passes through the second sliding holes 17 and is connected to the threaded holes of the corresponding leaf pieces of the hinges 13, so that when the hinges 13 are opened and closed, the leaf pieces and the second sliding holes 17 on the corresponding side are slidably matched front and back; Figure 1 and Figure 5 As shown, a cylinder 12 is installed on one of the mounting brackets 2, and the piston rod of the cylinder 12 is connected to the portion of the first limiting rod 14 extending out of the upper surface of the first sliding hole 16; Figure 2 As shown, the side guardrails 3 are installed on the protective brackets on both sides of the conveyor 1; Figure 3 and Figure 4As shown, the two ends of the two sets of middle guardrails 4 are respectively hinged together with the end faces of the corresponding hinges 13, and the middle guardrails 4 are driven to approach or move away from the side guardrails 3 by the opening and closing of the hinges 13. The installation cabinet 10 is fixedly installed at the middle position of the rear side of the conveyor 1, and a negative pressure pump 11 is installed in the installation cabinet 10 or on the side; Figure 1 and Figure 2 As shown, the scissor lift 9 is installed on the side of the installation cabinet 10 close to the conveyor 1 and above the conveyor 1, the scissor lift 9 is connected to the housing 8 below, the housing 8 is connected to the fixed frame 7 below, and is specifically connected to the outer frame, the filling head 5 is installed in the fixed frame 7, and the filling head 5 is in the filling area above the conveyor belt between the two installation brackets 2. The negative pressure adsorption end of the oil suction pipe 6 is connected to the negative pressure pump 11 through a quick release joint.

[0060] Instructions for use are as follows:

[0061] First, the lifting stroke of the scissor lift 9 is set according to the height of the canned container, and the height of the filling head 5 is adjusted according to the position of the canned container mouth, so that the sleeve filling head 5 fills from the canned container wall when discharging oil; the oil output of the filling head 5 is set according to the capacity of the canned container.

[0062] Then, the cylinder 12 is started according to the size of the canned container, and the piston rod of the cylinder 12 pushes the first limiting rod 14 to slide in the first sliding hole 16 along the length direction of the conveyor belt. In actual use, the first limiting rod 14 can also be slid manually to adjust the opening and closing angle of the hinge 13; when the first limiting rod 14 slides to the right, it drives the two second limiting rods 15 to slide to the front and rear sides of the second sliding hole 17 respectively, the distance between the two second limiting rods 15 increases, the hinge 13 opens, and the middle guardrail 4 approaches the side guardrail 3; when the first limiting rod 14 slides to the left, it drives the two second limiting rods 15 to slide to the center of the second sliding hole 17 respectively, the distance between the two second limiting rods 15 decreases, the hinge 13 gradually closes, and the middle guardrail 4 is driven to approach the side guardrail 3 by opening the hinge 13, and the middle guardrail 4 is driven to move away from the side guardrail 3 by closing the hinge 13. The distance between the middle guardrail 4 and the side guardrail 3 can protect small canned containers of various types.

[0063] Finally, the position of the filling head 5 along the length direction and the width direction of the conveyor belt is adjusted according to the specific position of the canned container.

[0064] During filling, the conveyor 1 is started to convey the canned container. The hinge 13 opens in a corresponding fan-shaped state according to the size of the canned container, which can effectively guide the canned container. The side guardrail 3 and the middle guardrail 4 cooperate to protect the canned container passing through, which can prevent the canned container from tipping over. When the canned container reaches the bottom of the filling head 5, the conveyor 1 stops. The filling head 5 reaches the preset filling height through the scissor lift 9, and fills from the wall of the canned container, which can effectively prevent the generation of bubbles. After the filling reaches the set capacity, the filling head 5 is slowly lifted, and the negative pressure pump 11 generates negative pressure in the oil suction pipe 6, which generates suction on the lubricating oil remaining on the filling head 5, which can prevent the lubricating oil from dripping and contaminating the site and the outer surface of the filling container. After the filling is completed, the conveyor 1 is started again to transport the canned container and carry out the next filling work cycle.
