Description

Technical Field

[0001] The present invention relates to the technical field of shoe-making equipment, and particularly to a rotary table device for injection shoe-making and a shoe-making equipment. Background Art

[0002] In traditional injection shoe-making equipment, in order to accelerate the molding process of the shoe sole, the left and right shoe molds are usually supplied with circulating cooling water to cool the molded shoes. This cooling method introduces cooling water into the interior of the shoe mold and uses the principle of heat conduction to take away the heat of the shoe sole, accelerating the reduction of the temperature of the shoe sole, thereby improving the molding efficiency of the shoe sole. However, due to the relatively small thickness of the shoe sole, the contact area between the left and right shoe molds and the shoe sole to be molded is limited, so the effect of accelerating cooling is limited, and the improvement of the molding efficiency of the shoe sole is not significant. In addition, due to the relatively large volume of the conventional rotary table base, it is generally produced in a split manner and assembled by subsequent screwing for easy production and transportation. Correspondingly, the errors and tolerances accumulated during the assembly process will cause errors during the glue injection process of the subsequent shoe mold assembly, affecting the quality and consistency of the product.

[0057] For the convenience of understanding the embodiments of the present invention, the following will further explain and illustrate by taking specific embodiments as examples in conjunction with the accompanying drawings, and each embodiment does not constitute a limitation to the embodiments of the present invention.

[0058] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0060] Refer to Figures 1 - 16 , the present invention discloses a turntable device for injection molding shoes, including a turntable assembly. The turntable assembly includes a turntable base 1 and a main shaft. The turntable base 1 is integrally formed and is rotationally assembled on the main shaft. A cooling plate 2 and a shoe mold assembly 3 are provided on the turntable assembly. The shoe mold assembly 3 includes a left shoe mold 31, a right shoe mold 32, and a bottom mold 33. The bottom mold 33 is disposed between the left shoe mold 31 and the right shoe mold 32. The left shoe mold 31 and / or the right shoe mold 32 is provided with a first liquid cooling channel 34. The left shoe mold 31, the right shoe mold 32, and the bottom mold 33 are all disposed on the cooling plate 2, and the left shoe mold 31, the right shoe mold 32, and the bottom mold 33 are all in contact with the cooling plate 2. The cooling plate 2 is provided with a second liquid cooling channel 21.

[0061] Specifically, the turntable assembly includes a turntable base 1 and a main shaft. The turntable base 1 is rotationally assembled on the main shaft so that the turntable base 1 can rotate, and then cooperate with the injection molding head to process all the shoe mold components 3 arranged on the turntable base 1 one by one. A cooling plate 2 and shoe mold components 3 are provided on the turntable assembly. The shoe mold components 3 include a left shoe mold 31, a right shoe mold 32 and a bottom mold 33. The bottom mold 33 is arranged between the left shoe mold 31 and the right shoe mold 32 and is used for forming the bottom surface of the shoe sole. The left shoe mold 31 and the right shoe mold 32 are used for forming the contour of the shoe sole and the style of the side surface of the shoe sole. Generally, during use, a shoe last 9 is inserted between the left shoe mold 31 and the right shoe mold 32, so as to form a cavity for shoe sole forming among the shoe last 9, the left shoe mold 31, the right shoe mold 32 and the bottom mold 33. Of course, for the shoe sole that can be formed by the left shoe mold 31, the right shoe mold 32 and the bottom mold 33, the shoe last 9 can be not used. The turntable assembly is mainly used to drive the shoe mold components 3 arranged above the turntable assembly to rotate, so as to realize the injection molding of multiple shoe mold components 3 that may be arranged on the turntable assembly one by one.

[0062] In addition, the integral molding of the turntable base 1 avoids the problem of error and tolerance accumulation caused by individual installation and adjustment, ensures the consistent and accurate position height of all the shoe mold components 3, and thus improves the product quality and consistency of the products produced by the shoe mold components 3.

[0063] Refer to Figures 1 - 6 As shown, the left shoe mold 31 and the right shoe mold 32 can, according to requirements, choose to set the first liquid cooling channel 34 in the left shoe mold 31, set the first liquid cooling channel 34 in the right shoe mold 32 or both the left shoe mold 31 and the right shoe mold 32 are provided with the first liquid cooling channel 34. There is no limitation here. The following examples are all based on the situation where both the left shoe mold 31 and the right shoe mold 32 are provided with the first liquid cooling channel 34. The first liquid cooling channel 34 in the left shoe mold 31 and the first liquid cooling channel 34 in the right shoe mold 32 can be selected in series or in parallel. The specific form of coolant guidance can be freely selected according to requirements. The cooling plate 2 is installed on the turntable assembly to rotate with the rotation of the turntable assembly. The cooling plate 2 is provided with a second liquid cooling channel 21 for the coolant to pass through the second liquid cooling channel 21 to cool the cooling plate 2. The left shoe mold 31, the right shoe mold 32 and the bottom mold 33 are all arranged on the cooling plate 2. The cooling plate 2 cools the left shoe mold 31, the right shoe mold 32 and the bottom mold 33 in contact with it, so that the left shoe mold 31 and the right shoe mold 32 can be cooled by the first liquid cooling channel 34 and also be cooled by the cooling plate 2 at the same time. Correspondingly, even if there are large differences in the cooling effects of the first liquid cooling channel 34 and the second liquid cooling channel 21, through the contact heat conduction between the left shoe mold 31 and the right shoe mold 32 and the cooling plate 2, the temperature dynamic balance among the left shoe mold 31, the right shoe mold 32, the bottom mold 33 and the cooling plate 2 can be realized, thus improving the overall quality and consistency of the processed shoe soles.

[0064] Optionally, the first liquid cooling channel 34 in the left shoe mold 31 and the first liquid cooling channel 34 and the second liquid cooling channel 21 in the right shoe mold 32 may be arranged in series and / or in parallel, which is not limited here.

[0065] See also Figure 2 As shown, in some embodiments, both the left shoe mold 31 and the right shoe mold 32 are provided with a first liquid cooling channel 34 , and the first liquid cooling channel 34 in the left shoe mold 31 is connected to the first liquid cooling channel 34 in the right shoe mold 32 .

[0066] Specifically, an independent first liquid cooling channel 34 is provided inside the left shoe mold 31 and the right shoe mold 32 for directly and quickly cooling the shoe mold, and the first liquid cooling channel 34 of the left shoe mold 31 is connected with the first liquid cooling channel 34 of the right shoe mold 32. This structure allows the coolant to flow in the left shoe mold 31 and the right shoe mold 32, that is, the first liquid cooling channel 34 of the left shoe mold 31 and the first liquid cooling channel 34 of the right shoe mold 32 are connected in series, thereby facilitating the design of the overall water supply pipe and the water outlet pipe, and facilitating the design and layout of the overall liquid cooling system.

[0067] See also Figure 7 and Figure 8 As shown, in some embodiments, the turntable assembly includes a turntable base 1 , the turntable base 1 is provided with a cooling plate assembly groove 11 , and the cooling plate 2 is embedded in the cooling plate assembly groove 11 .

[0068] Specifically, since the cooling plate 2 is directly assembled on the turntable base 1, the overall height of the shoe mold assembly 3 will increase, resulting in an increase in the operator's operating height, which affects the convenience of operation. More importantly, the shoe mold assembly 3 usually adopts a left and right opening design. In order to ensure that the left shoe mold 31 and the right shoe mold 32 will not interfere with the cooling plate 2 located at the bottom of the shoe mold assembly 3 when rotating, it is necessary to add a padding block at the bottom of the shoe mold handle during modification. These padding blocks are mounted on the support rod connecting the turntable base 1 and the turntable top seat, so that the shoe mold handle is away from the bottom fixing point of the support rod. Although this design solves the interference problem, it leads to a decrease in the stability of the overall structure, which in turn affects the clamping accuracy. The decrease in clamping accuracy will cause dimensional deviations or surface defects in the sole molding process, affecting product quality.

[0069] Correspondingly, the turntable assembly includes a turntable base 1, the turntable base 1 is provided with a cooling plate assembly groove 11, and the cooling plate 2 is embedded in the cooling plate assembly groove 11. The height of the shoe mold assembly 3 increased by adding the cooling plate 2 is greatly reduced. This structure completely avoids the problem of increasing the overall height of the shoe mold assembly 3 due to adding the cooling plate 2 in the traditional method, so there is no need to set a pad under the shoe mold handle, simplifying the structure.

[0070] Furthermore, since there is no need to adjust the height of the shoe mold assembly 3 through a raising block, the shoe mold assembly 3 can be stably fitted directly to the cooling plate 2, thereby avoiding the problem of loosening or offsetting of the support rod caused by the traditional raising block, and avoiding the problem of reduced locking accuracy caused by the corresponding increase in the installation position of the shoe mold handle after the shoe mold assembly 3 is raised.

[0071] The cooling plate 2 is embedded in the cooling plate assembly groove 11, that is, the cooling plate 2 is embedded in the turntable base 1, ensuring that the left shoe mold 31 and the right shoe mold 32 will not interfere with the cooling plate 2 or the pipeline when opening, closing or rotating. The cooling plate 2 is fixed by the cooling plate assembly groove 11, and there is no need to install additional pads or adjust the height of the shoe mold assembly 3, which reduces the complexity of assembly. At the same time, the embedded design of the cooling plate 2 facilitates quick disassembly and maintenance, reduces the additional operating steps caused by the removal of the pads, and improves the equipment maintenance efficiency.

[0072] See also Figure 5 and Figure 6 As shown, in some embodiments, the second liquid cooling channel 21 has a water inlet 22 and a water outlet 23 , and the water inlet 22 and the water outlet 23 are respectively located at two ends of the second liquid cooling channel 21 .

[0073] Specifically, the second liquid cooling channel 21 has a water inlet 22 and a water outlet 23, and the water inlet 22 and the water outlet 23 are respectively located at the two ends of the second liquid cooling channel 21. Correspondingly, the water inlet 22 can be connected to an external water supply pipe, and the water outlet 23 can be connected to an external water outlet pipe, so that the external coolant is introduced into the second liquid cooling channel 21 from the water inlet 22, and then the coolant flows out of the cooling plate 2 through the water outlet 23. When the coolant flows in the second liquid cooling channel 21, it will take away the heat in the cooling plate 2, so that the cooling plate 2 always maintains a low temperature state to ensure the cooling efficiency. Among them, the second liquid cooling channel 21 can freely choose the arrangement method in the cooling plate 2 as needed, and it can effectively keep the temperature of the cooling plate 2 stable. The coolant can be water or other liquids with high specific heat capacity, fast thermal conductivity and stable chemical properties, which are not limited here.

[0074] See also Figures 7 - 9 As shown, in some embodiments, the turntable base 1 is provided with a first pipe groove 12 at a position corresponding to the water inlet 22 of the cooling plate assembly groove 11, and a groove of the first pipe groove 12 close to one end of the cooling plate 2 corresponds to the water inlet 22 of the cooling plate 2, so that a water outlet pipe close to the cooling plate 2 is embedded in the first pipe groove 12 for installation, and the turntable base 1 is provided with a second pipe groove 13 at a position corresponding to the water outlet 23 of the cooling plate assembly groove 11, and a groove of the second pipe groove 13 close to one end of the cooling plate 2 corresponds to the water outlet 23 of the cooling plate 2, so that a water supply pipe close to the cooling plate 2 is embedded in the second pipe groove 13 for installation.

[0075] Specifically, since the cooling plate 2 is embedded in the cooling plate assembly groove 11, correspondingly, the water inlet 22 and the water outlet 23 of the cooling plate 2 are generally partially or entirely within the cooling plate assembly groove 11. To facilitate the connection between the water inlet 22 and the external water supply pipe and between the water outlet 23 and the external water discharge pipe, and also to prevent interference with the mold opening and closing movements of the shoe mold assembly 3 by the external water supply pipe and the external water discharge pipe, the turntable base 1 is provided with a first pipe groove 12 at the position corresponding to the water inlet 22 of the cooling plate assembly groove 11, that is, the turntable base 1 is provided with the first pipe groove 12 at the position corresponding to the water inlet 22 of the cooling plate 2 assembled in the cooling plate assembly groove 11. The notch of the first pipe groove 12 near the cooling plate 2 corresponds to the water inlet 22 of the cooling plate 2, so that the external water supply pipe can be embedded in the first pipe groove 12 and then correspondingly connected to the water inlet 22. Similarly, the turntable base 1 is provided with a second pipe groove 13 at the position corresponding to the water outlet 23 of the cooling plate assembly groove 11, that is, the processing part is provided with the second pipe groove 13 at the position corresponding to the water outlet 23 of the cooling plate 2 assembled in the cooling plate assembly groove 11. The notch of the second pipe groove 13 near the cooling plate 2 corresponds to the water outlet 23 of the cooling plate 2, so that the external water discharge pipe can be embedded in the second pipe groove 13 and then correspondingly connected to the water outlet 23.

[0076] Refer to Figures 7 - 9 As shown, in some embodiments, the turntable base 1 is provided with a plurality of cooling plate assembly grooves 11, and all the cooling plate assembly grooves 11 are evenly distributed along the circumferential direction of the turntable base 1;

[0077] Adjacent N cooling plate assembly grooves 11 are grouped as a set. The turntable base 1 is provided with a first pipe groove 12 at the cooling plate assembly groove 11 on one side of each set of cooling plate assembly grooves 11, and the first pipe groove 12 corresponds to the water inlet 22 of the cooling plate 2 installed in this cooling plate assembly groove 11;

[0078] The turntable base 1 is provided with a second pipe groove 13 at the cooling plate assembly groove 11 on the other side of each set of cooling plate assembly grooves 11, and the second pipe groove 13 corresponds to the water outlet 23 of the cooling plate 2 installed in this cooling plate assembly groove 11;

[0079] In each set of cooling plate assembly grooves 11, a third pipe groove 14 is provided between two adjacent cooling plate assembly grooves 11. One end of the third pipe groove 14 corresponds to the water outlet 23 of the cooling plate 2 near the first pipe groove 12, and the other end corresponds to the water inlet 22 of the cooling plate 2 near the second pipe groove 13, so that the external transfer pipe connecting adjacent two cooling plates 2 can be embedded and installed on the turntable base 1.

[0080] Specifically, when multiple cooling plate assembly grooves 11 are provided on the turntable base 1, all the cooling plate assembly grooves 11 are evenly distributed along the circumferential direction of the turntable base 1 to meet the requirement of individually injection-molding the shoe mold assemblies 3 provided on the cooling plate assembly grooves 11 during the polar rotation of the turntable base 1. Adjacent N cooling plate assembly grooves 11 are set as a group. At the cooling plate assembly grooves 11 at both ends of one group, a first pipe groove 12 is provided at the cooling plate assembly groove 11 on one side, and the first pipe groove 12 corresponds to the water inlet 22 of the cooling plate 2 installed in this cooling plate assembly groove 11. A second pipe groove 13 is provided at the cooling plate assembly groove 11 on the other side, and the second pipe groove 13 corresponds to the water outlet 23 of the cooling plate 2 installed in this cooling plate assembly groove 11. Except for the cooling plate assembly grooves 11 at both ends of each group of cooling plate assembly grooves 11, the cooling plates 2 in the cooling plate assembly grooves 11 between the above two cooling plate assembly grooves 11 can be connected in series. Specifically, the turntable base 1 is provided with a third pipe groove 14 between two adjacent cooling plate assembly grooves 11. One end of the third pipe groove 14 corresponds to the water outlet 23 of the cooling plate 2 close to the first pipe groove 12, and the other end corresponds to the water inlet 22 of the cooling plate 2 close to the second pipe groove 13, so that the external adapter pipe connecting two adjacent cooling plates 2 is embedded in the turntable base 1 for installation.

[0081] The working principle of the above structure after installing the external water supply pipe, external water outlet pipe and external adapter pipe is as follows:

[0082] The external water supply pipe introduces the coolant into the liquid cooling channel inside the cooling plate 2 through the water inlet 22 of the cooling plate 2 on one side of each group of cooling plate assembly grooves 11. After passing through the liquid cooling channel, the coolant flows into the external adapter pipe through the water outlet 23 of this liquid cooling plate, and then enters the water inlet 22 of the cooling plate 2 adjacent to this cooling plate 2 through the external adapter pipe, and so on. Until the coolant reaches the water outlet 23 of the last cooling plate 2, it is discharged to the outside through the external water outlet pipe, thereby achieving the effect of series cooling of multiple cooling plates 2. In many different application scenarios, factors such as the type of coolant, the flow rate of the coolant, the material of the cooling plate 2, the material of the bottom mold 33 to be cooled, and the shape of the sole to be formed will all affect the cooling effect when the cooling plate 2 is provided. Correspondingly, on the basis that the cooling plate 2 can achieve the effect of indirectly cooling the sole to be formed, the specific number of cooling plates 2 connected in series through the third pipe groove 14 and the external adapter pipe can be freely selected. The specific number of series connections is not limited here, and it is only necessary to complete the cooling of all the cooling plates 2 connected in series on the basis of the above various influencing conditions.

[0083] Refer to Figure 10 and Figure 11As shown, in some embodiments, the cooling plate assembly groove 11 penetrates through the turntable base 1. A limiting member 15 is provided on the side of the cooling plate assembly groove 11 away from the contact surface between the cooling plate 2 and the shoe mold assembly 3. When the cooling plate 2 is assembled in the cooling plate assembly groove 11, the cooling plate 2 abuts against the limiting member 15 to prevent the cooling plate 2 from slipping out of the cooling plate assembly groove 11.

[0084] Specifically, the cooling plate assembly groove 11 is designed to penetrate through the turntable base 1, so that the cooling plate 2 has a relatively large assembly space. Correspondingly, the volume of the cooling plate 2 can be designed to be larger, thereby improving the heat conduction amount. A limiting member 15 is provided on the side of the cooling plate assembly groove 11 away from the contact surface between the cooling plate 2 and the shoe mold assembly 3, so that when the cooling plate 2 is assembled in the cooling plate assembly groove 11, the cooling plate 2 abuts against the limiting member 15 to prevent the cooling plate 2 from slipping out of the cooling plate assembly groove 11.

[0085] Refer to Figure 10 and Figure 11 As shown, in some embodiments, the limiting member 15 is a limiting plate, and the limiting plate is provided on the side of the cooling plate assembly groove 11 away from the contact surface between the cooling plate 2 and the shoe mold assembly 3.

[0086] Specifically, the limiting plate is provided on the side of the cooling plate assembly groove 11 away from the contact surface between the cooling plate 2 and the shoe mold assembly 3. This can ensure that after the cooling plate 2 is inserted into the cooling plate assembly groove 11, it abuts against the limiting plate to prevent the cooling plate 2 from sliding out of the assembly groove, and will not interfere with the contact between the cooling plate 2 and the shoe mold assembly 3. The structure of the limiting member 15 adopting a limiting plate can provide a larger contact area for the cooling plate 2, thereby improving the installation stability of the cooling plate 2.

[0087] On the basis of the structure of the limiting member 15 adopting a limiting plate, the turntable base 1 is respectively provided with a first installation groove 16 and a second installation groove 17 on two opposite sides of the cooling plate assembly groove 11. One end of the limiting plate is assembled in the first installation groove 16, and the other end is assembled in the second installation groove 17.

[0088] Specifically, the first installation groove 16 is located on one side of the cooling plate assembly groove 11, and the second installation groove 17 is located on the other side of the cooling plate assembly groove 11, opposite to the first installation groove 16. When the limiting plate is assembled, one end of the limiting plate sinks into the first installation groove 16 for fixed assembly, and the other end of the limiting plate sinks into the second installation groove 17 for fixed assembly, so that the size of the entire turntable device in the longitudinal direction will not become larger due to the addition of the limiting plate, which is beneficial to the management of the longitudinal height. Correspondingly, this structure also reduces the additional space requirement, and is particularly suitable for application scenarios with strict requirements on the equipment height.

[0089] In addition, after the limiting plate is sunken and installed, it will not affect the movement of the sole molding injection machine during the production process, avoiding the inconvenience of operation or potential safety hazards caused by the protrusion of the limiting member 15.

[0090] In some embodiments, the limiting member 15 is a limiting convex block, and there are multiple limiting convex blocks, and all the limiting convex blocks are arranged in the cooling plate assembly groove 11 for supporting the cooling plate 2.

[0091] Specifically, all the limiting convex blocks are arranged on the groove wall of the cooling plate assembly groove 11, so that when the cooling plate 2 is embedded in the cooling plate assembly groove 11, the cooling plate 2 abuts against the limiting convex blocks, thereby forming a support for the cooling plate 2. Correspondingly, in order to improve the uniform support of the limiting convex blocks for the cooling plate 2, the limiting convex blocks can be arranged at equal intervals. Preferably, when the cooling plate assembly groove 11 is rectangular, a limiting convex block can be arranged in the middle of each of the four side walls of the cooling plate assembly groove 11, so as to realize the uniform support of the cooling plate 2 and avoid deformation or damage caused by uneven local stress.

[0092] Refer to Figure 1 and Figure 3 As shown in the figure, in some embodiments, the cooling surface of the cooling plate 2 for contacting the shoe mold assembly 3 is flush with the surface of the turntable base 1.

[0093] Specifically, the cooling surface of the cooling plate 2 for contacting the shoe mold assembly 3 is flush with the surface of the turntable base 1, that is, the upper surface of the cooling plate 2 is flush with the upper surface of the turntable base 1, so that the cooling plate 2 and the turntable base 1 cooperate to provide a flat assembly platform. This enables the shoe mold assembly 3 to be placed stably and accurately above the cooling plate 2, reducing the assembly difficulties caused by unevenness. Of course, the cooling plate 2 and the turntable base 1 cooperate to provide a flat assembly platform, which also facilitates the assembly of other components.

[0094] Referring to Figure 12 As shown in the figure, the present invention also provides a shoe-making device, including a driving mechanism 4 and the above-mentioned rotary table device for injection shoe-making, and the turntable base 1 is in transmission connection with the driving mechanism 4, so that the driving mechanism 4 drives the turntable base 1 to rotate.

[0095] Specifically, as an option, the driving mechanism 4 can be a motor, and the motor is in transmission connection with a speed reducer, and the motor is in transmission connection with the rotary table device through the speed reducer. Of course, the driving mechanism 4 can also be a polar driving mechanism. Correspondingly, the turntable base 1 can also be driven by the polar driving mechanism to drive the turntable base 1 arranged on the rotating shaft base, so as to drive the turntable base 1 to rotate around the rotating shaft base at a fixed rotation angle.

[0096] In some embodiments, the turntable driving mechanism includes a plurality of driven sprocket wheels fixed to the bottom of the turntable base 1, and a motor, a speed reducer, a driving dial 61, a notched disc 62, and a pin 63 mounted on the base 8. The motor is connected to the input end of the speed reducer by a belt. The output end of the speed reducer is equipped with the driving dial 61, on which the notched disc 62 and the pin 63 are mounted. The notched disc 62 is adapted to the positioning groove of the driven sprocket wheel, and the pin 63 is adapted to the side wall of the notched disc 62. When the driving dial 61 rotates, the notched disc 62 and the pin 63 will act on the positioning groove and the side wall of the notched disc 62 in sequence to realize the rotation of the turntable base 1.

[0097] The distance between the centers of two adjacent driven sprocket wheels is the first distance. The turntable 1 is driven to rotate each time based on the first distance as the standard. Similarly, the distance between two adjacent external sole mold assemblies arranged above the cooling plate 2 is also the same as the first distance. Thus, when the driven sprocket wheel rotates a distance of the first distance, the external sole mold assembly correspondingly moves a distance of the first distance, thereby ensuring that the injection head can always accurately align with the injection hole of the external sole mold assembly corresponding to the opening of the injection head.

[0098] Since the turntable driving mechanism is a prior art, it will not be elaborated here too much. For details, refer to the patent CN212241855U.

[0099] Refer to Figure 13 and Figure 14 As shown, in some embodiments, the shoe-making equipment further includes a lubrication assembly, which includes an oil tank 51, an oil pump 52, and an oil delivery pipe 53. The oil tank 51 has an oil outlet and an oil inlet. The oil pump 52 is arranged on the oil delivery pipe 53. One end of the oil delivery pipe 53 is provided with a filter screen and enters the interior of the oil tank 51 through the oil outlet, so as to send the lubricating oil in the oil tank 51 to the other end of the oil delivery pipe 53 through the oil pump 52. At least one oil dripping port is provided at the other end of the oil delivery pipe 53. The oil dripping port corresponds to the turntable driving mechanism 4 and is located above it, for dripping the lubricating oil onto the turntable driving mechanism 4.

[0100] In some embodiments, two oil dripping ports are arranged on the oil delivery pipe 53, respectively located above the side surfaces of the notched disc 62 and the pin 63, for dripping oil onto the side surfaces of the notched disc 62 and the pin 63. During the contact process of the notched disc 62 and the pin 63 with the driven sprocket wheel respectively, the lubricating oil will be transferred to the driven sprocket wheel, thereby realizing the lubrication of the entire turntable driving mechanism 4.

[0101] Optionally, the pipe section of the oil delivery pipe 53 provided with the oil dripping port can be set as a copper pipe 54, so as to improve the stability of this pipe section and ensure that the lubricating oil dripping from the oil dripping port can drip to the predetermined position.

[0102] In some embodiments, in order to facilitate the collection and recycling of the lubricating oil, a first oil collecting tray 71 is provided below the driving dial 61, the notched disc 62 and the pin 63. The first oil collecting tray 71 is provided with an oil return port 711, and the oil return port 711 is connected to the oil inlet through an oil return pipe to collect the lubricating oil in the first oil collecting tray 71.

[0103] Furthermore, since the driven sprocket will come into contact with the lubricating oil during the contact process with the notched disc 62 and the pin 63, in order to facilitate the collection of the lubricating oil on all the driven sprockets, an arc-shaped second oil collecting tray 72 is provided vertically below the driven sprocket. Both ends of the second oil collecting tray 72 are provided with notches, and the notches at both ends are located above the first oil collecting tray 71, so that the lubricating oil in the second oil collecting tray 72 can flow into the first oil collecting tray 71, and through the connection between the first oil collecting tray 71 and the fuel tank 51, the recycling and reuse of the lubricating oil are completed.

[0104] Participate Figure 13 、 Figure 15 and Figure 16 As shown in

[0105] In some embodiments, the base 8 is equidistantly provided with a plurality of support assemblies 81. The support assembly 81 includes a support base 811, a support member 812, a screw 813, a nut 814, a gasket 815 and a flexible pad 816. One end of the support member 812 is inserted into the support base 811, and the other end is connected with a wear-resistant plate 817. The flexible pad 816 and the gasket 815 are sequentially arranged inside the support base 811. The support member 812 contacts the flexible pad 816. The screw 813 is inserted into the support base 811 from the opposite end of the support member 812 and is in threaded cooperation with the support base 811. By the extending length of the screw 813 relative to the support base 811, the gasket 815, the flexible pad 816 and the support member 812 can be sequentially pushed to move, so as to adjust the overall height of each support assembly 81, and then adapt to different assembly environments to ensure that the wear-resistant plates 817 of each support assembly 81 can stably contact the turntable base 1. The nut 814 is sleeved on the screw 813 and is located outside the support base 811, so as to prevent the screw 813 from moving.

[0105] Optionally, the flexible pad 816 can be made of rubber material, so that after the screw 813 is adjusted, a slight height difference can be adjusted adaptively through the flexible pad 816.

[0106] Optionally, a convex block 8171 is provided on one side of the wear-resistant plate 817 facing the support member 812, and a groove 8121 matching with the convex block 8171 is provided at one end of the support member 812 for installing the convex block 8171. By assembling the convex block 8171 in the groove 8121 and then welding the wear-resistant plate 817 and the support member 812, the connection strength and connection accuracy can be improved.

[0107] In addition, since the turntable base 1 is relatively heavy, it will rub against the wear-resistant plate 817. During the long-term friction process, due to the heat generated by the wear-resistant plate 817 and the turntable base 1, problems such as accelerated damage to the surfaces of the wear-resistant plate 817 and the turntable base 1 and increased friction will occur, affecting the normal use of the turntable base 1.

[0108] To solve the above problems, the wear-resistant plate 817 is made of pig iron, and the part of the turntable base 1 that comes into contact with the wear-resistant plate 817 is made of wrought iron. The hardness of pig iron is greater than that of wrought iron, which can greatly alleviate the problem of increased friction caused by wear.

[0109] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
