Description

Technical Field

[0001] This utility model belongs to the field of mixing equipment for coatings, paints and the like, and particularly relates to a single-layer transmission separation structure for paint mixers with multi-layer mixing structures. Background Technology

[0002] Currently, most automotive refinish paint mixers on the market are long, multi-layered structures. The paint buckets to be mixed are fitted with special mixing lids and placed under mixing heads on each shelf. A power drive unit located on one side of the frame simultaneously rotates all the mixing heads via a transmission mechanism, thus mixing the paint in the buckets to obtain a uniform color. The desired paint can then be extracted according to the mixing arrangement.

[0003] Generally, this type of mixer has six or more racks from top to bottom. In actual use, some users may request that the mixing heads on a certain rack not be used, or that paint buckets not be placed on certain racks. If the mixing heads on that rack are running idle, it is a waste of power for the drive unit. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to avoid the stirring heads on a certain shelf plate from running idle, and to achieve that the stirring heads on a certain shelf plate do not stir or all stir. Therefore, a single-layer transmission separation structure for paint mixer is provided.

[0005] To solve the above problems, this utility model is achieved through the following technical solution: The paint mixer uses a single-layer transmission separation structure, including a frame plate, on one side of which a transmission mechanism is installed; the other side of the transmission mechanism is connected to the main transmission horizontal shaft; a split-type transmission module is set on the frame plate, with the main transmission horizontal shaft and the driven transmission horizontal shaft connected to each end of the split-type transmission module respectively; The split-type transmission module includes: a split sleeve connected to the main drive shaft, a split drive shaft connected to the driven shaft, and a shift fork handle for controlling the separation of the split sleeve from the split drive shaft.

[0006] The transmission mechanism is equipped with a transmission gear, and a bevel gear is provided at the end of the main transmission horizontal shaft. The transmission gear meshes with the bevel gear.

[0007] The separation sleeve is a hollow tube. An annular groove is provided on the outer circular surface of the right side of the separation sleeve. A fork is slidably fitted inside the annular groove. A fork handle is installed on the bracket plate at the fork. The sliding assembly is such that the fork cannot transmit force to the outer circular surface of the separation sleeve in the radial direction, but can transmit thrust to the side circular surface of the annular groove in the axial direction.

[0008] The shift fork handle includes a handle support mounted on the frame plate, a rotating shaft on the handle support, a handle that can rotate around the rotating shaft, a slotted hole on the handle, and a control pin extending from the shift fork into the slotted hole.

[0009] The frame plate is also provided with slots, which include a first slot and a second slot that are connected to each other. The height of the first slot is greater than the height of the second slot, and the height of the second slot is slightly greater than the thickness of the handle. When the handle is located in the first slot, the split-type transmission module is in a constant engaged state. When the handle is located in the second slot, the split-type transmission module is in a constant disengaged state.

[0010] A strip groove connecting to the end is provided on the left side of the separating sleeve, and a radially extending shaft linkage block is provided at the right end of the main drive horizontal shaft. The shaft linkage block is engaged in the strip groove on the left side of the separating sleeve.

[0011] A strip-shaped hole is provided on the middle section of the separating sleeve, and a transmission pin is provided at the left end of the separating drive shaft. The transmission pin extends into the strip-shaped hole in the middle section of the separating sleeve.

[0012] A compression spring is fitted onto the outer circumference of the split drive shaft, with its two ends pressing against the right end of the split sleeve and the left end of the split drive shaft, respectively.

[0013] At least one paint bucket transmission mechanism is provided on the drive shaft. A paint bucket stirring cap insertion port is provided on the frame plate below each paint bucket transmission mechanism. A transmission connection mechanism is provided on each paint bucket stirring cap. When the paint bucket stirring cap passes through the paint bucket stirring cap insertion port, the transmission connection mechanism on it is connected to the paint bucket transmission mechanism on the drive shaft.

[0014] A paint mixer employing the single-layer transmission separation structure includes a housing, with multiple racks arranged inside the housing. A top-to-bottom transmission mechanism is installed on one side of each rack, connecting the multiple racks together. A single-layer transmission separation structure is provided on each rack.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a single-layer transmission separation structure on each shelf, which enables the stirring heads on a certain shelf to either not stir or all stir when only one power drive device is set up, thus making the device more flexible in use.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figure 1 As shown, the paint mixer uses a single-layer transmission separation structure, including a frame plate 1. The frame plate 1 can be set inside the housing 100 of the paint mixer, so that multiple frame plates 1 can be set inside the housing 100 of the paint mixer.

[0020] The frame plate 1 is a hollow rectangular shell, but it can also be other shapes, as long as it can ensure that the internal components can be installed in an orderly manner. A top-to-bottom transmission mechanism 2 is installed on one side of the frame plate 1, and the transmission mechanism 2 connects multiple frame plates 1 together.

[0021] As shown in the attached diagram, the transmission mechanism 2 is installed on the left side of the frame plate 1. The transmission mechanism 2 is a drive shaft and is driven by the power drive device 11. For the entire mechanism, the power drive device 11 can be a single device, thus saving on device configuration.

[0022] like Figure 2 , Figure 6 As shown, a main transmission horizontal shaft 4 is provided on the right side of the transmission mechanism 2 via a bearing 3. The left end of the main transmission horizontal shaft 4 is connected to the transmission mechanism 2. In this embodiment, a transmission gear is installed on the transmission mechanism 2, and a bevel gear is provided at the end of the main transmission horizontal shaft 4. The transmission gear meshes with the bevel gear, so that the transmission mechanism 2 and the main transmission horizontal shaft 4 are mutually driven through the bevel gears installed at their respective ends.

[0023] A split-type transmission module is installed on the frame plate 1. The two ends of the split-type transmission module are connected to the main transmission horizontal shaft 4 and the driven transmission horizontal shaft 5, respectively.

[0024] like Figure 3 , Figure 8 , Figure 9 As shown, the split-type transmission module includes: a split sleeve 6 connected to the main transmission horizontal shaft 4, a split transmission shaft 7 connected to the driven transmission horizontal shaft 5, and a shift fork handle 8 for controlling the separation of the split sleeve 6 and the split transmission shaft 7.

[0025] like Figure 6 , Figure 8 , Figure 9 As shown, the separating sleeve 6 is a hollow tube. A strip groove 6-1 connecting to the end is provided on the left side of the separating sleeve 6. A first strip hole 6-2 is opened on the middle part of the tube body of the separating sleeve 6. An annular groove 6-3 is provided on the outer circular surface of the right part of the separating sleeve 6. A fork 6-4 is slidably fitted inside the annular groove 6-3. The sliding assembly is explained as follows: the fork 6-4 cannot transmit force to the outer circular surface of the separating sleeve 6 in the radial direction, but can transmit thrust to the side circular surface of the annular groove 6-3 in the axial direction.

[0026] like Figure 6 , Figure 7 As shown, a fork handle 8 is installed on the frame plate 1 at the fork 6-4. The fork handle 8 includes a handle support 6-5 installed on the frame plate 1. A rotating shaft 6-6 is provided on the handle support 6-5. A handle 6-7 that can rotate around the rotating shaft 6-6 is provided on the rotating shaft 6-6. A second slotted hole 6-8 is also provided on the handle 6-7. In order for the handle to control the left and right movement of the fork 6-4, a control pin 6-9 extends out of the fork 6-4. The control pin 6-9 extends into the second slotted hole 6-8. By moving the handle 6-7 left and right, the control pin 6-9 drives the fork 6-4 to transmit thrust to the side surface of the annular groove 6-3 in the axial direction.

[0027] Furthermore, to ensure the split-type transmission module can maintain a constant disengaged or engaged working state, a slot 6-10 is provided on the frame plate 1. Slot 6-10 includes a first slot and a second slot that are interconnected. The height of the first slot is greater than the height of the second slot, and the height of the second slot is slightly greater than the thickness of the handle 6-7. When the handle 6-7 is located in the first slot of slot 6-10, the split-type transmission module is in a constant engaged state, i.e., in a transmission state. When the handle 6-7 is located in the second slot of slot 6-10, the split-type transmission module is in a constant disengaged state, i.e., in a non-transmission state.

[0028] like Figure 3 , Figure 4 , Figure 6 As shown, the main drive horizontal shaft 4 and the separation sleeve 6 are two separable components. In order to transmit the torque of the main drive horizontal shaft 4 to the separation sleeve 6, in this embodiment, a radially extending shaft linkage block 4-1 is provided at the right end of the main drive horizontal shaft 4. At a certain angle, the shaft linkage block 4-1 can be inserted into the strip groove 6-1 on the left side of the separation sleeve 6, thereby realizing the direct connection and transmission between the main drive horizontal shaft 4 and the separation sleeve 6.

[0029] It should be noted that the transmission shaft 5 and the separate transmission shaft 7 are fixedly connected by pins. Of course, other connection methods can also be used, or they can be manufactured as one piece.

[0030] To ensure more reliable transmission between the main drive shaft 4 and the separating sleeve 6, in this embodiment, a compression spring 9 is fitted onto the outer circumference of the separating drive shaft 7. The two ends of the compression spring 9 press against the right end of the separating sleeve 6 and the left end of the separating drive shaft 7, respectively. Figure 8 , Figure 9 As shown. The compression spring 9 continuously applies a leftward thrust to the separator sleeve 6, which makes the transmission connection between the main drive shaft 4 and the separator sleeve 6 more reliable.

[0031] On the other hand, in order to reliably transmit the torque of the separating sleeve 6 to the separating drive shaft 7, a drive pin 7-1 is provided at the left end of the separating drive shaft 7. The drive pin 7-1 extends into the first strip hole 6-2 in the middle of the separating sleeve 6. The two can slide relative to each other in the axial direction and can also transmit torsional force in the radial direction.

[0032] At least one paint bucket transmission mechanism is provided on the transmission horizontal shaft 5. A paint bucket stirring cap insertion port 10 is provided on the frame plate 1 below each paint bucket transmission mechanism. Each paint bucket stirring cap is provided with a transmission connection mechanism. When the paint bucket stirring cap passes through the paint bucket stirring cap insertion port 10, its transmission connection mechanism is engaged with the paint bucket transmission mechanism on the transmission horizontal shaft 5.

[0033] The transmission mechanism for the paint bucket here consists of multiple bevel gears mounted on the transmission horizontal shaft 5. The transmission connection mechanism on the stirring cover of each paint bucket is as follows: a bevel gear is mounted on the stirring shaft. When the bevel gear on the transmission horizontal shaft 5 is engaged with the bevel gear on the stirring shaft, the inside of the paint bucket can be stirred.

[0034] In another embodiment, the paint bucket transmission mechanism is as follows: a vertical drive shaft is set directly on the transmission horizontal shaft 5 and on the frame plate 1 below each bevel gear. The upper end of the drive shaft is provided with a driven bevel gear that meshes with the bevel gear on the transmission horizontal shaft 5, and the lower end of the drive shaft extends to the bottom of the frame plate 1. A drive fork or drive pawl is installed at the lower end of the drive shaft. At this time, the stirring shaft of the paint bucket with the stirring cover is provided with a drive pawl or fork.

[0035] Both of the above methods are existing technologies and will not be elaborated further here.

[0036] A paint mixer includes a housing 100, within which multiple racks 1 are arranged. A top-to-bottom transmission mechanism 2 is installed on one side of each rack 1, connecting the multiple racks 1 together. Each rack 1 has a single-layer transmission separation structure. This structure allows for the mixing heads on certain racks to either not mix or all mix, making the device more flexible in use.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
