DETAILED DESCRIPTION

[0032] To make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.

[0034] In the description of the utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0035] The utility model provides a kind of coating waste collecting device with heating function, as shown in Figures 1 to 8 Coating waste collecting device is arranged below the lip 51 of coating assembly, for recycling slurry dropped at the lip 51, and coating assembly includes coating die 5, and base 4 supporting coating die 5 and driving coating die 5 to move, and the lip 51 is the discharge port of coating die 5;Coating waste collecting device with heating function can be arranged independently of coating assembly, keep fixed position, it can also be fixedly connected with coating assembly, and move synchronously with the movement of coating assembly, when fixed position, coating waste collecting device with heating function should at least cover the movement range of lip 51 in adjustment process, to ensure sufficient collection of dropped slurry.

[0036] In order to enable the coating waste collection device with heating function to move with the coating assembly, the coating waste collection device with heating function can be fixed on the coating die head 5 or directly fixed on the base 4. It includes a collection tank 1 for receiving slurry and a heating component 2 for heating the collection tank 1. Since the heating component 2 is heated, the slurry dripping into the collection tank 1 will not have reduced fluidity due to cooling, effectively preventing the slurry from being unevenly distributed and piling up near the lip 51, ensuring the smooth progress of coating.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] Example 1

[0039] As an embodiment of the present invention, this embodiment provides a coating waste collection device with heating function. In this embodiment, the coating waste collection device with heating function includes a collection tank 1 and a heating component 2 for heating the collection tank 1. The heating component 2 is fixed at the bottom of the collection tank 1. In this embodiment, the heating component 2 is an electric heating tube.

[0040] Specifically, such as Figure 1 As shown, the collection tank 1 is a tank with an open top and an outwardly folded flange at the opening. A fastener is formed on the flange, and the collection tank 1 is detachably connected to the base 4 through the fastener. The detachable connection between the fastener and the base 4 can be achieved in a way known and common in the art. For example, a through hole can be provided on the fastener, and a threaded hole can be provided on the base 4. The fastener and the base 4 can be fixed by screws. Alternatively, other methods such as buckles and hooks can be used to fix the two together, which will not be elaborated here.

[0041] Furthermore, the area of ​​the horizontal cross-section of the collection tank 1 gradually increases along the direction close to the opening of the collection tank 1, forming an involute opening. Due to the relatively large opening, it can effectively prevent the slurry from leaking to the outside and improve the slurry collection effect.

[0042] A heating component 2 is provided on the outer side of the wall of the collection tank 1. The collection tank 1 is heated by the heating component 2. Since the temperature requirement for heating the collection tank 1 is different from the coating temperature, the temperature of the heating component 2 can be controlled independently. Considering that the collection tank 1 needs to be cleaned and needs to be disassembled and cleaned frequently, the heating component 2 is detachably connected to the collection tank 1. The detachable connection can be achieved by common detachable connection methods in the field, such as screw connection, snap connection, and plug connection. During normal operation, the heating component 2 is fixed on the collection tank 1, and the collection tank 1 is fixed on the base 4 to collect the slurry that falls off at the lip 51. When the collection tank 1 needs to be cleaned, the collection tank 1 is removed from the base 4, and the heating component 2 is separated for cleaning.

[0043] Example 2

[0044] As another embodiment of the present invention, the difference between this embodiment and the first embodiment is that the coating waste collection device with heating function also includes a fixing component 3.

[0045] In this embodiment, the fixing component 3 is fixedly connected to the base 4 of the coating component, and the heating component 2 is fixed on the collection tank 1 and is detachably connected to the fixing component 3 along with the collection tank 1. In this solution, the collection tank 1 is not directly connected to the base 4, which makes it easier to install and disassemble, facilitates cleaning and maintenance by operators, and reduces the difficulty of disassembly.

[0046] Specifically, such as Figure 2 As shown, the fixing component 3 includes a support part and a fixing part. The support part forms a vertically upward-opening receiving cavity. The collection tank 1 is directly placed into the receiving cavity and fixed by abutment and limiting with the inner wall of the receiving cavity. When disassembling, the operator only needs to take the collection tank 1 out of the receiving cavity without additional disassembly operation. The fixing part is connected to the support part, and the fixing component 3 is connected to the base 4 through the fixing part. When the fixing component 3 is installed in place, the receiving cavity is located directly below the lip 51 and opens vertically upward to facilitate the insertion and removal of the collection tank 1.

[0047] Furthermore, the cavity also includes a clearance structure 31 for avoiding the heating component 2. The form of the clearance structure 31 can be adjusted according to actual conditions. For example, as one possible implementation in this embodiment, such as... Figure 3 As shown, the clearance structure 31 is configured as an opening opposite the position of the heating component 2; or as another possible implementation, such as Figure 4 As shown, the avoidance structure 31 can also be a sub-accommodating cavity 32 formed on the inner wall of the accommodating cavity at the position corresponding to the heating component 2.

[0048] Furthermore, in order to fully support and fix the collection tank 1, the depth of the receiving cavity is the same as the depth of the collection tank 1, so that when the collection tank 1 is installed in place, the flange at the opening abuts against the edge of the opening of the receiving cavity.

[0049] In other embodiments, such as Figure 5 As shown, a disassembly port can also be provided on the side of the receiving cavity adjacent to the upper opening. The collection tank 1 can be installed and disassembled through the disassembly port. When disassembling and assembling, the flange of the collection tank 1 first abuts against the edge of the opening of the collection tank 1. The cooperation between the edge of the opening and the flange guides the collection tank 1 to be installed in place, further reducing the difficulty of disassembly and assembling and improving the user experience.

[0050] Example 3

[0051] As another embodiment of the present invention, the difference between this embodiment and embodiment two is that the heating component 2 is positioned differently.

[0052] In this embodiment, the heating component 2 is mounted on the fixing component 3. When disassembling and cleaning the collection tank 1, it is not necessary to separate the heating component 2 and the collection tank 1 separately, further simplifying the disassembly and assembly process; specifically, as shown... Figure 6 As shown, the heating component 2 is fixed on the support. Since the support is in direct contact with the collection tank 1, it can more effectively control the temperature of the collection tank 1.

[0053] As one specific implementation method of this embodiment, such as Figure 7 As shown, the support part includes two parallel crossbars 33 and several support rods connecting the two crossbars 33. The projection of the support rods on the plane where the two crossbars 33 are located is perpendicular to the crossbars 33. The support rods are bent away from the lip 51 to form a receiving cavity for receiving the collection groove 1 between the two crossbars 33. The heating component 2 is connected to the support rods.

[0054] Considering the shape of the collection tank 1, the support rod includes a first support section 34, a second support section 35, and a third support section 36 connected in sequence. The first support section 34 and the third support section 36 are respectively connected to two crossbars 33, and the two ends of the second support section 35 are respectively connected to the first support section 34 and the third support section 36. When the collection tank 1 is installed in place, the second support section 35 supports the bottom of the collection tank 1, and the first support section 34 and the third support section 36 are respectively attached to the sides of the collection tank 1, thereby achieving stable support for the collection tank 1. In order to further improve the support effect, the lengths of the first support section 34 and the third support section 36 can be adjusted according to the width of the side wall of the collection tank 1, so that when the collection tank 1 is installed in place, the flange at the opening of the collection tank 1 abuts against the two crossbars 33, further improving the support effect of the collection tank 1.

[0055] The heating component 2 can be configured to be connected to the first support section 34, the second support section 35, or the third support section 36, depending on the actual situation. When multiple heating components 2 are provided, they can be located on the same support section or on different support sections. As a specific implementation of this embodiment, the heating component 2 includes an electric heating rod for heating the collection tank 1. The electric heating rod is located on the second support section 35 to heat the bottom of the collection tank 1. The second support section 35 has a fixing ring on the side away from the receiving cavity for fixing the electric heating rod. The fixing rings on several second support sections 35 are aligned so that the electric heating rod can be inserted into the cavity formed by the fixing rings for fixing.

[0056] Further, the communication pipes can be arranged between the fixing rings, the communication pipes extend into the fixing rings and are connected with the inner ring surfaces of the fixing rings, the electric heating rods are directly and detachably connected with the communication pipes, the installation difficulty of the electric heating rods can be further reduced, meanwhile, the communication pipes also provide further fixing effect for the supporting rods, the relative static state between the supporting rods is maintained, and the structural stability of the bearing part is improved.

[0057] In other embodiments, the structure for fixing the heating assembly 2 on the supporting rods can also be adaptively adjusted according to different styles of the heating assembly 2, for example, the heating assembly 2 is arranged as a heating coil pipe, and buckles or elastic clamping jaws for fixing the heating coil pipe can be correspondingly arranged on the supporting rods; the technical solutions obtained by making conventional replacement on the style of the heating assembly 2 and the fixing mode of the heating assembly 2 on the supporting rods also fall within the protection scope of the utility model.

[0058] Embodiment four

[0059] As another embodiment of the utility model, the embodiment further makes the following improvements on the basis of the embodiment three.

[0060] In the embodiment, as shown in Figure 8 The coating waste collecting device with the heating function further comprises a guide plate 6 arranged between the lip 51 of the coating assembly and the collecting groove 1, the slurry falling off from the lip 51 first contacts the guide plate 6 and then drops to a specific area of the collecting groove 1 under the guidance of the guide plate 6, thereby better avoiding the slurry from leaking to the outside and improving the collecting effect of the collecting groove 1 on the slurry.

[0061] Specifically, the guide plate 6 in the embodiment is detachably fixed on the base 4 and located above the collecting groove 1, and the guide plate 6 is arranged in an inclined manner along the direction close to the collecting groove 1, so that the projection of the lower end of the guide plate 6 in the vertical direction falls into the bottom wall of the collecting groove 1, thereby the slurry guided by the guide plate 6 drops more to the bottom of the collecting groove 1, and the collecting effect of the slurry is improved.

[0062] Correspondingly, the heating assembly 2 in the embodiment is arranged at the bottom of the collecting groove 1 and heats the bottom of the collecting groove 1, so that the dropped slurry is kept at a certain temperature, thereby better leveling at the bottom of the collecting groove 1 and avoiding the stacking and the situation of the slurry from being too high.

[0063] The above merely describes preferred embodiments of the present application and is not intended to limit the present application in any form, although the present application has been disclosed as above with preferred embodiments, however, it is not intended to limit the present application, any person skilled in the art without departing from the technical scheme of the present application can make some changes or modifications to the above-mentioned technical content for equivalent embodiments, the implementation schemes in the above-mentioned embodiments can be further combined or replaced, as long as it does not deviate from the technical scheme of the present application, any simple modification, equivalent change and modification made to the above-mentioned embodiments according to the technical essence of the present application still belongs to the scope of the present application.
