Brief Description of the Drawings

[0017] Figure 1 It is one of the three-dimensional diagrams of the utility model;

[0018] Figure 2 It is a structural schematic diagram of the utility model when the box body is removed;

[0019] Figure 3 It is the second stereogram of the utility model. [Specific implementation method]

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] like Figures 1 to 3 As shown, a centralized wax supply system comprises a frame 1, on which are disposed a plurality of wax cylinders 2 capable of storing wax liquid, a wax pipe 3 connected to the inner cavity of the wax cylinder 2 is disposed at the bottom of the wax cylinder 2, a one-way wax inlet branch pipe 4 and a one-way wax outlet branch pipe 5 are disposed on the wax pipe 3, a plurality of one-way wax inlet branch pipes 4 are connected to a wax inlet main pipe 6 for inputting wax liquid, a plurality of one-way wax outlet branch pipes 5 are connected to a wax outlet main pipe 7 capable of being connected to a plurality of wax injection machines for wax supply, a wax discharge device 8 capable of pushing the wax liquid in a wax cylinder 2 into the wax pipe 3 so that the wax liquid flows from the one-way wax outlet branch pipe 5 into the wax outlet main pipe, and a driving device 9 capable of driving the wax discharge device 8 to move to the position of the wax cylinder 2 to be discharged so as to push the wax liquid in the wax cylinder 2. In a specific implementation, the output end of the wax outlet main pipe 7 can be connected to the feed port of each wax injection machine through a plurality of branch pipes. After the wax discharge device 8 sends the wax liquid in the wax cylinder 2 out through the one-way wax outlet branch pipe 5, the wax outlet main pipe 7 diverts the wax liquid to each wax injection machine through each branch pipe. When the wax supply work is suspended, the wax inlet main pipe 6 can be used to input the wax liquid, and it can be replenished into each wax cylinder 2 through each one-way wax inlet branch pipe 4, waiting for the next centralized wax supply work.

[0022] Specifically, the wax cylinder 2 has an opening at the upper end, and a piston 20 is relatively slidably provided in the wax cylinder 2 to seal the opening at the upper end of the wax cylinder 2. The wax discharge device 8 includes an oil cylinder 81, and the oil cylinder 81 is provided with a piston push rod 811 that can extend into the wax cylinder 2 to push the piston 20 to push out the wax liquid in the wax cylinder 2. When the oil cylinder 81 is working, the piston push rod pushes the piston 20 to slide downward, and when the wax liquid is replenished by the wax inlet main pipe, the wax liquid replenished in the wax cylinder 2 will push the piston 20 to slide upward and reset.

[0023] The utility model drives an oil cylinder 81 to move on the frame 1 through a driving device 9. When the oil cylinder 81 moves above a wax cylinder 2, the oil cylinder 81 pushes the wax liquid in the wax cylinder 2 into the wax pipe 3, so that the wax liquid flows out into the wax outlet main pipe 7 through the one-way wax outlet branch pipe 5. The wax outlet main pipe 7 supplies wax to multiple wax injection machines, realizing centralized wax supply, which is beneficial to improving production efficiency. The utility model has a simple structure. Only one oil cylinder and a driving device are used to discharge the wax liquid in each wax cylinder, which is beneficial to saving costs.

[0024] like Figure 2 As shown, the wax cylinders 2 are arranged in two rows, and the driving device 9 includes a transverse driving device for driving the wax discharge device 8 to move transversely and a longitudinal driving device for driving the wax discharge device 8 to move longitudinally. The longitudinal driving device driving the wax discharge device 8 to move to the adjacent second row is considered as longitudinal movement, and the transverse driving device driving the wax discharge device 8 to move between adjacent wax cylinders 2 in each row is considered as transverse movement. Specifically, the wax cylinders 2 are arranged in two rows along the width direction of the box body 12, and each row has eight wax cylinders 2 evenly arranged, with a total of sixteen wax cylinders 2. In this way, the wax storage capacity is large, which can well meet the needs of one-time wax filling and long-term wax supply, so as to improve production efficiency.

[0025] Specifically, the transverse driving device includes a first guide rail 91 extending along the length direction of the frame 1, a first slide 92 slidably arranged on the first guide rail 91, a first nut seat 97 fixed to the first slide 92, a first driving motor 93 fixed to the frame 1, and a first screw 90 installed on the first nut seat 97 and driven to rotate by the first driving motor 93. The longitudinal driving device and the wax removal device 8 are arranged on the first slide 92. Figure 2 As shown, two first guide rails are arranged on the frame 1 at a relatively spaced interval, and linear sliders are installed on both sides of the bottom of the first slide 92, and the linear sliders can slide on the corresponding first guide rails 91 respectively. The first drive motor 93 is a servo motor, and the first drive motor 93 is connected to the first screw 90 through a reducer. The first drive motor 93 drives the first screw 90 to rotate and drives the first nut seat 97 to move along the first screw 90, so that the first nut seat 97 drives the first slide 92 to move horizontally along the first guide rail 91 on the frame 1.

[0026] Specifically, the longitudinal driving device includes a second guide rail 94 extending along the length direction of the first slide 92 and perpendicular to the first guide rail 91 in the horizontal direction, a second slide 95 slidably arranged on the second guide rail 94, a second nut seat 98 fixed on the second slide 95, a second drive motor 96 fixed on the second slide 95, and a second screw 99 installed on the second nut seat 98 and driven to rotate by the second drive motor 96. The wax removal device 8 is installed on the second slide 95. Figure 2As shown, two second guide rails 94 are arranged on the first slide 92 at a distance from each other, and linear sliders are also installed on both sides of the bottom of the second slide 95. The linear sliders on the second slide 95 can slide on the corresponding second guide rails 94 respectively. The second drive motor 96 is a servo motor, and the second drive motor 96 is connected to the second screw 99 through a reducer. The second drive motor drives the second screw 99 to rotate and drives the second nut seat 98 to move along the second screw 99, so that the second nut seat 98 drives the second slide 95 to move longitudinally along the second guide rail 94 on the frame 1.

[0027] Specifically, when the second drive motor 96 is installed on the second slide 95, the piston push rod 811 passes downward through the second slide 95, and a long groove 921 is provided on the first slide 92 for the piston push rod 811 to pass through. When the second drive motor 96 drives the second slide 95 to slide along the second guide rail 94, the piston push rod 811 slides back and forth along the long groove 921.

[0028] In the utility model, a wax inlet check valve for controlling the wax liquid to flow from the one-way wax inlet branch pipe 4 into the wax pipe 3 in one direction and a wax inlet solenoid valve for controlling the on-off of the wax liquid in the one-way wax inlet branch pipe 4 are provided in the one-way wax outlet branch pipe 5. A wax outlet check valve for controlling the wax liquid to flow out from the wax pipe 3 in one direction into the one-way wax outlet branch pipe 5 and a wax outlet solenoid valve for controlling the on-off of the one-way wax outlet branch pipe 5 are provided in the one-way wax outlet branch pipe 5. When the wax liquid needs to be replenished, the wax inlet solenoid valve is opened and the wax outlet solenoid valve is closed, and the wax liquid in the wax inlet main pipe flows from the one-way wax inlet branch pipe 4 into the wax pipe 3 in one direction, and then is filled into the wax cylinder 2; when the wax needs to be discharged, the wax outlet solenoid valve is opened and the wax inlet solenoid valve is closed, and the wax liquid stored in the wax cylinder 2 flows out from the wax pipe 3 in one direction into the one-way wax outlet branch pipe 5, and then supplies wax to multiple wax injection machines through the wax outlet main pipe.

[0029] like Figure 3 As shown, a box 12 is provided on the frame 1, and the wax cylinder 2 is provided in the box 12. The box 12 is provided with an injection port 121 for injecting a heat preservation medium into the box 12. By injecting the heat preservation medium at the injection port, a good heat preservation effect can be achieved for the wax cylinder 2. Specifically, the heat preservation medium can be selected from heat transfer oil.
