Description

Technical Field

[0001] The utility model relates to the field of coating machine equipment, and more specifically, it relates to a waste material recovery device for a coating machine. Background Art

[0002] A coating machine is a mechanical device used to apply various coating materials on substrates (such as paper, plastic film, metal foil, fabric, etc.) to enhance the performance or functional characteristics of the substrates. The coating machine used in the textile industry usually has a fabric guiding roller for driving the fabric and a coating roller for coating.

[0003] During the coating process, a scraper is usually provided to define the thickness of the coating on the fabric. After the scraper thins the excess coating on the fabric, some coating will adhere to the surface of the scraper. In addition, some dried and condensed coating will also adhere to the surface of the coating roller for coating. To reduce the waste of coating, in the prior art, a scraping knife is usually provided to scrape and recover the coating adhered and condensed on the coating roller and the scraper. However, the operation of the scraping knife often requires a driving source such as a servo motor, which consumes energy such as electric energy, to drive the scraping knife to work, thus increasing the manufacturing cost of the equipment and the energy consumption.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a waste material recovery device for a coating machine, which has the advantages of low manufacturing cost, small energy consumption, and recyclable coating.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: A waste material recovery device for a coating machine includes an equipment main body provided with a coating roller and a first scraper. A scraping assembly is slidably connected to a position near the first scraper inside the equipment main body. The scraping assembly includes scraping blades located on both sides of the first scraper and connecting pieces located at both ends of the scraping blades for connecting the scraping blades. One end of one of the connecting pieces away from the scraping blade is provided with a transmission assembly. The coating roller drives the scraping assembly to reciprocate along the height direction of the first scraper through the transmission assembly.

[0007] The utility model is further provided as follows: A first rotating gear is fixedly connected to one side of the coating roller close to the transmission assembly. The transmission assembly includes a hollow gear connected to the first rotating gear through a transmission chain. The hollow gear is rotatably connected to the equipment main body through a rotating groove opened on the side, and the inner ring wall of the hollow gear is provided with a sawtooth surface composed of several inclined curved surfaces and straight surfaces corresponding to the number of the curved surfaces.

[0008] The present utility model is further configured as follows: The transmission assembly further includes a double-tooth row fixedly connected to the connecting member, a semi-tooth gear meshing between the double-tooth rows, and a control assembly fixedly connected to the side of the semi-tooth gear away from the connecting member for moving away from or approaching the serrated surface of the hollow gear.

[0009] The present utility model is further configured as follows: The control assembly includes a connecting block fixedly connected to the side of the semi-tooth gear away from the connecting member and a limiting block disposed inside the connecting block and fixedly connected with a pressing switch extending outside the device main body. A sliding groove one penetrating both sides of the connecting block is formed in the connecting block. Two abutting blocks with end faces corresponding to the shape of the serrated surface of the hollow gear are arranged on both sides extending out of the sliding groove one. An elastic member one is fixedly connected between the two abutting blocks. The limiting block is disposed between the two abutting blocks.

[0010] The present utility model is further configured as follows: The sides of the opposite end faces of the limiting block and the two abutting blocks are all arranged to be inclined towards the direction of the connecting member.

[0011] The present utility model is further configured as follows: A sliding groove two for two scraping blades to slide is formed in the connecting member. Elastic members two that always give the two scraping blades a tendency to approach each other are fixedly connected to the opposite end faces of the two scraping blades.

[0022] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0023] Embodiment: A waste material recovery device for a coating machine, as Figures 1-4 shown, includes an equipment main body 1 provided with a coating roller 11 and a first scraper 12. A scraping component 3 is slidably connected to a position near the first scraper 12 inside the equipment main body 1. The scraping component 3 includes two scraping blades 31 located on both sides of the first scraper 12 and connecting pieces 32 located at both ends of the scraping blades 31 for connecting the two scraping blades 31. A transmission component 4 is provided at one end of the connecting piece 32 away from the scraping blade 31. The coating roller 11 drives the scraping component 3 to reciprocate along the height direction of the first scraper 12 through the transmission component 4 to scrape and clean the waste material condensed and adhered to the surface of the scraper. Through the design of the transmission component 4, the power source for the operation of the scraping component 3 and the coating roller 11 use the same power source, so that when the coating roller 11 rotates, it can drive the scraping component 3 to operate, reducing the manufacturing cost and energy consumption of the present utility model. At the same time, the waste material is scraped and recycled, improving the utilization rate of the coating material and reducing the waste of the coating material.

[0024] As Figures 3-5As shown in the figure, a first rotating gear 111 is fixedly connected to one side of the coating roller 11 close to the transmission assembly 4. The transmission assembly 4 includes a hollow gear 41 connected to the first rotating gear 111 through a transmission chain 112. The hollow gear 41 is rotatably connected to the equipment main body 1 through a rotating groove opened on the side, and the inner ring wall of the hollow gear 41 is provided with a serrated surface composed of a plurality of inclined curved surfaces and straight surfaces corresponding to the number of the curved surfaces. During scraping, the equipment is operated so that only the coating roller 11 rotates. The first rotating gear 111 rotates, and drives the hollow gear 41 to rotate through the transmission chain 112 meshing with the first rotating gear 111.

[0025] As Figures 3-5 As shown in the figure, the transmission assembly 4 further includes a double-tooth row 43 fixedly connected to the connecting member 32, a half-tooth gear 42 meshing between the double-tooth rows 43, and a control assembly 5 fixedly connected to the side of the half-tooth gear 42 away from the connecting member 32 for moving away from or approaching the serrated surface of the hollow gear 41. With this structural design, when the half-tooth gear 42 with only half of the meshing teeth rotates, it can only mesh with one row of the double-tooth rows 43, thereby driving the double-tooth row 43 to make a reciprocating motion, driving the scraping assembly 3 to make a reciprocating motion to clean the surface of the first scraper 12. Through the design of the control assembly 5, it is possible to choose to let the control assembly 5 move away from the hollow gear 41 during the coating process, so that the scraping assembly 3 has no power source and cannot operate. After the coating is completed, let the control assembly 5 approach and fit the hollow gear 41, so that the hollow gear 41 can drive the half-tooth gear 42 to rotate through the control assembly 5, thereby driving the scraping assembly 3 to operate. The structural design is simple and stable, providing high convenience for the operation of the equipment.

[0026] As Figures 3-5As shown in the figure, the control component 5 includes a connection block 51 fixedly connected to the side of the semi-toothed gear 42 away from the connection member 32, and a limiting block 54 disposed within the connection block 51 and fixedly connected to a pressing switch extending outside the device body 1. A first sliding groove 511 penetrating both sides of the connection block 51 is formed within the connection block 51. Two abutting blocks 52 with end faces corresponding to the tooth surface shape of the hollow gear 41 are provided on both sides extending out of the first sliding groove 511. An elastic member 53 composed of spring coils is fixedly connected between the two abutting blocks 52. The elastic member 53 is used to give the two abutting blocks 52 a tendency to approach each other. The sides of the opposite end faces of the limiting block 54 and the two abutting blocks 52 are all inclined towards the direction of the connection member 32, facilitating the squeezing of the limiting block 54 between the two abutting blocks 52. When the limiting block 54 extends between the two abutting blocks 52 and causes the two abutting blocks 52 to extend out of the first sliding groove 511, the abutting blocks 52 abut against the tooth surface of the hollow gear 41. When the hollow gear 41 is driven to rotate by the first rotating gear 111, the straight surface of the tooth surface abuts against the abutting blocks 52 to drive the connection block 51 and the semi-toothed gear 42 to rotate. When the limiting block 54 disengages from the connection block 51, under the elastic force of the elastic member 53, the two abutting blocks 52 approach each other, causing the abutting blocks 52 to disengage from the hollow gear 41. Thus, the rotation of the hollow gear 41 cannot drive the semi-toothed wheel to rotate, cutting off the power source of the scraping component 3. The design of this structure is simple and reasonable, and fully considers the working state of the coating machine.

[0027] As Figures 3-6 shown, a second sliding groove 321 is formed within the connection member 32 of the scraping component 3. Elastic members 33 that always give the two scraping blades 31 a tendency to approach each other are fixedly connected to the opposite end faces of the two scraping blades 31. The elastic members 33 are composed of spring coils. Through the design of the elastic members 33, the two scraping blades 31 are always in close contact with both sides of the first scraper 12, making the scraping effect of the scraping blades 31 on the remaining material adhered to the first scraper 12 better. The top of the first scraper 12 is rotatably connected to a second scraper 13 for scraping the remaining material on the surface of the coating roller 11. One end of the second scraper 13 is fixedly connected to a fixing knob 131 extending out of the end face of the first scraper 12. Through the frictional force between the fixing knob 131 and the side wall of the first scraper 12, the second scraper 13 can form a fixed angle with the first scraper 12, facilitating the adjustment of the position of the second scraper 13, enabling the second scraper 13 to better scrape the remaining material on the surface of the coating roller 11, and also allowing the second scraper 13 to rotate relative to the first scraper 12 during coating to prevent interference with the coating work of the coating roller 11. The bottom end of the first scraper 12 is slidably connected to a recovery groove 2 on the device body 1. The remaining material scraped from the first scraper 12 and the coating roller 11 will fall into the recovery groove 2 under the action of gravity. The design of the recovery groove 2 facilitates the collection and treatment of the remaining material.

[0028] Working principle: After rotating the second scraper 13 to the position where it fits the surface of the coating roller 11, turn the fixing knob 131 to fix the position of the second scraper 13 by the frictional force between the fixing knob 131 and the first scraper 12. At this time, start the main body 1 of the device to rotate the coating roller 11. Through the design of the transmission chain 112, the first rotating gear 111 drives the hollow gear 41 to rotate. When the limiting block 54 in the control component 5 is placed between the two abutting blocks 52 and squeezes the two abutting blocks 52 to fit the serrated surface of the hollow gear 41, when the hollow gear 41 rotates, it will drive the connecting block 51 and the semi-tooth gear 42 fixedly connected to the connecting block 51 through the fitting surface with the abutting block 52. Also, through the setting of the semi-tooth gear 42 and the double-tooth row 43, the scraping blade 31 reciprocates along the height direction of the first scraper 12 to clean and recycle the remaining material on the surface of the first scraper 12. When the limiting block 54 in the control component 5 moves away from the connecting block 51, the two abutting blocks 52 in the connecting block 51 are separated from the hollow gear 41 under the elastic force of the first elastic member 53, so that the scraping assembly 3 remains stationary without a power source, and the scraped remaining material will fall into the recovery tank 2 under the action of gravity, which is convenient for the treatment and recycling of the remaining material. The scraping assembly 3 of the present utility model and the coating roller 11 use the same power source, which reduces energy consumption and improves the utilization rate of the coating at the same time.

[0029] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
