Description

Technical Field

[0001] The utility model relates to the technical field of resistor processing equipment, in particular to an adjusting mechanism for a feeding wheel scraper of a resistor coating machine. Background Art

[0002] Currently, when an insulating layer, a color ring, or a protective layer needs to be coated on the periphery of a resistor, a resistor coating machine needs to be used for automatic loading to increase operating efficiency.

[0003] The present applicant has filed application number 202022439336.1, which discloses a resistor coating apparatus comprising a frame, a conveyor track, a conveyor belt, a drive assembly for driving the conveyor belt, a through hole A for carrying resistors, a loading mechanism, and at least one coating assembly. The coating assembly comprises a support seat fixed to the frame, a pinch wheel for compressing the resistors, the pinch wheel positioned above the conveyor belt, a loading wheel positioned below the conveyor belt and corresponding to the pinch wheel, a drive mechanism for driving the pinch wheel and the loading wheel, a conveyor track having an opening corresponding to the loading wheel, and a trough for holding insulating coating on the frame corresponding to and below the loading wheel. The above-described technical solution can automatically apply an insulating layer, a color ring, or a protective layer to the outer periphery of the resistor, thereby improving production efficiency and reducing production costs.

[0004] The above application can realize automatic coating of resistors, but the loading wheel cannot be adjusted radially along the width direction of the conveyor belt and cannot adapt to coating openings at different positions on the conveyor belt. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art and provide an adjustment mechanism for the feeding wheel of a resistance coating machine which can be radially adjusted in the width direction of the conveyor belt to adapt to coating openings at different positions on the conveyor belt and has an adjustable lifting height of the feeding wheel scraper.

[0006] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: an adjustment mechanism of a feeding wheel scraper of a resistance coating machine, comprising a support seat, an adjusting rod is provided at one end of the support seat, a rotating rod is provided at the other end of the support seat, a feeding wheel scraper is provided on the rotating rod, and the adjusting rod is provided with a width adjustment mechanism for adjusting the support seat along the length direction of the adjusting rod, the width adjustment mechanism comprises a fixed seat fixedly connected to one end of the adjusting rod, the other end of the adjusting rod passes through the support seat and is threadedly connected to an adjusting member, the adjusting member abuts against the support seat, the support seat is provided with a transmission wheel at a position opposite to the adjusting member, the transmission wheel is rotatably arranged on the adjusting rod, an elastic member is provided between the transmission wheel and the fixed seat, and the rotating adjustment member makes the support seat close to the fixed seat and press the elastic member or expands the elastic member and makes the support seat away from the fixed seat to achieve adjustment of the support seat along the length direction of the adjusting rod.

[0007] With the above technical solution, since the positions of the paint openings for conveyor belts of different widths are different, the existing loading wheel scraper is directly replaced when used for different conveyor belts, or adjusted through nuts and mounting slots. However, when adjusting through the nuts, the loading wheel scraper needs to be positioned after adjustment, and the subsequent installation procedure is relatively cumbersome. Therefore, the present application realizes the adjustment of the loading wheel scraper along the length direction of the adjusting rod by tightening or loosening the adjusting member, and the position of the support seat is elastically positioned by the elastic member. The fixed seat can be fixed on the machine body. When the adjusting member is continuously tightened, the adjusting rod is continuously exposed from the adjusting member, and the position of the support seat is continuously close to the fixed seat. At this time, the elastic member is also continuously pressed by the support seat; and when the adjusting member is continuously loosened, the part of the adjusting rod exposed from the adjusting member is continuously retracted, and the support seat is elastically supported by the elastic member that is continuously returning to its position, thereby gradually moving away from the fixed seat. The distance adjustment between the support seat and the fixed seat can be achieved by only tightening and loosening the adjusting member. The elastic member can also realize adaptive elastic support for the support seat. No additional fixing screws are required to achieve relatively stable position adjustment of the loading wheel scraper, and the adjustment is convenient.

[0008] An adjustment mechanism for a loading wheel scraper of a resistor coating machine can be further configured as follows: a first baffle is provided above one end of the loading wheel scraper provided on the support seat, a second baffle is provided below one end of the adjusting rod provided on the support seat, a spring mounting hole is provided on the second baffle, and the spring mounting hole adjusts the lifting height of the loading wheel scraper by pulling down the second baffle and tilting up the first baffle through the spring.

[0009] By adopting the above technical solution, a spring is installed at the bottom through a spring mounting hole on the second baffle, so that one end of the support seat can be tilted downward, and the top of the second baffle is abutted against the machine body to achieve tilt limitation. Since one end of the second baffle is tilted, the height of the loading wheel scraper also begins to rise, that is, the height of the loading wheel is adjustable, so that the loading wheel scraper can be set close to the paint opening of the conveyor belt, so that it is more suitable for the paint opening of the conveyor belt.

[0010] An adjustment mechanism for a scraper of a feeding wheel of a resistance coating machine can be further configured as follows: a baffle sleeved on an adjustment rod is provided between the transmission wheel and the elastic member, and the baffle and the fixing seat are respectively in contact with both ends of the elastic member.

[0011] With the above technical solution, if the transmission wheel directly contacts the elastic part, hard contact will be generated between the two. As a result, when the transmission wheel continuously rotates, the elastic part will also continuously rotate, reducing the elasticity of the elastic part and thus reducing the service life of the elastic part. The transmission wheel and the elastic part are separated by the baffle. When the adjusting part is continuously tightened, the transmission wheel also continuously presses the elastic part through the baffle, which will not affect the transmission effect of the transmission wheel.

[0012] An adjustment mechanism for a feeding wheel scraper of a resistive coating machine can be further configured as follows: a height adjustment member is provided at one end of the feeding wheel scraper provided on the support seat, a mounting seat is provided on the height adjustment member for rotating and inserting one side of the feeding wheel scraper, an adjustment threaded hole is provided at the end of the height adjustment member away from the mounting seat, and the height position of the height adjustment member is limited by adjusting the threaded hole after the feeding wheel is lifted.

[0013] By adopting the above technical solution, a threaded rod can be set on the body of the coating machine, and the adjusting rod can be positioned by screwing it into the adjusting threaded hole. Since the scraper of the loading wheel is relatively thin, the function of the mounting seat is to prevent the position of the scraper of the loading wheel from being offset when it rotates, causing inaccurate glue coating position. This mounting seat can limit the scraper of the loading wheel.

[0014] An adjustment mechanism for a scraper of a feeding wheel of a resistance coating machine can be further configured as follows: the adjustment part is a hexagonal nut, the inner ring of which is screwed to the adjustment rod, the elastic part is a return spring, and when the adjustment part is loosened, the elastic part elastically returns to the support seat; when the adjustment part is tightened, the support seat is close to the fixed seat and the elastic part is pressed.

[0015] By adopting the above technical solution, the adjusting part is set as a hexagonal nut so that it can be tightened by a wrench when tightening, and it can be tightened tighter than the knob, so it will not loosen during use. The elastic part is set as a return spring so that when the adjusting part is loosened, the elastic force of the return spring itself can be used to support the support seat, so that the support seat can be elastically supported by the elastic part, thereby realizing the adjustment of the support seat along the length direction of the adjusting rod.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the protection examples of the present invention.

[0024] Example 1: Figure 1-Figure 5 The adjustment mechanism of the feeding wheel scraper of the resistance coating machine shown in the figure includes a support base 1, an adjustment rod 2 is provided at one end of the support base 1 along its width direction, a rotating rod 3 is provided at the other end of the support base 1 along its width direction, a feeding wheel scraper 4 is rotatably provided on the rotating rod 3, a first baffle 11 is provided above one end of the feeding wheel scraper 4 provided on the support base 1, and a second baffle 12 is provided below one end of the support base 1 provided with the adjustment rod 2, and a spring mounting hole 121 is provided on the second baffle 12, as shown in FIG. Figure 3As shown, the spring mounting hole 121 pulls down the second baffle 12 by the spring and makes the first baffle 11 tilt up to adjust the lifting height of the feeding wheel scraper 4. The support seat 1 is provided with a height adjustment member 13 at one end of the feeding wheel scraper 4. The height adjustment member 13 is provided with a mounting seat 131 for rotating and inserting one side of the feeding wheel scraper 4. The height adjustment member 13 is provided with an adjusting threaded hole 132 at one end away from the mounting seat 131. After the feeding wheel scraper 4 is lifted, the height position of the height adjustment member 13 is limited by adjusting the threaded hole 132. The adjusting rod 2 is provided with a support seat 1 is a width adjustment mechanism 5 that is adjusted along the length direction of the adjustment rod 2. The width adjustment mechanism 5 includes a fixed seat 51 fixedly connected to one end of the adjustment rod 2. The other end of the adjustment rod 2 passes through the support seat 1 and is threadedly connected to an adjustment member 52. The adjustment member 52 abuts against the support seat 1. The support seat 1 is provided with a transmission wheel 53 at a position opposite to the adjustment member 52. The transmission wheel 53 is rotatably arranged on the adjustment rod 2. An elastic member 54 is provided between the transmission wheel 53 and the fixed seat 51. A baffle 55 that is sleeved on the adjustment rod 2 is provided between the transmission wheel 53 and the elastic member 54. The baffle 55 and the fixing seat 51 are respectively in contact with the two ends of the elastic member 54. The rotating adjusting member 52 brings the support seat 1 close to the fixing seat 51 and compresses the elastic member 54, or expands the elastic member 54 and makes the support seat 1 away from the fixing seat 51 to achieve the adjustment of the support seat 1 along the length direction of the adjusting rod 2. The adjusting member 52 is a hexagonal nut, the inner ring of which is screwed to the adjusting rod 2. The elastic member 54 is a return spring. When the adjusting member 52 is rotated, the elastic member 52 elastically extends the support seat 1; when the adjusting member 52 is tightened, the support seat 1 is close to the fixing seat 51 and the elastic member 54 is compressed. Since the positions of the paint openings for conveyor belts of different widths are different, the existing loading wheel scraper 4 is directly replaced when used for different conveyor belts, or adjusted through nuts and mounting slots. However, when adjusting through nuts, the loading wheel scraper needs to be positioned after adjustment, and the subsequent installation procedures are relatively cumbersome. Therefore, the present application tightens or loosens the adjusting member 52 to adjust the loading wheel scraper 4 along the length direction of the adjusting rod 2, and uses the elastic member 54 to achieve elastic positioning of the support base 1, and the fixing base 51 can be fixed on the machine body, such as Figure 2 As shown, when the adjusting member 52 is continuously tightened, the adjusting rod 2 is continuously exposed from the adjusting member 52, and the position of the support seat 1 is continuously close to the fixed seat 51. At this time, the elastic member 54 is also continuously pressed by the support seat 1; Figure 1As shown, when the adjusting member 52 is continuously loosened, the part of the adjusting rod 2 exposed from the adjusting member 52 is continuously retracted, and the support seat 1 is elastically supported by the elastic member 54 that is continuously returning to its position, thereby gradually moving away from the fixed seat 51. The distance adjustment between the support seat 1 and the fixed seat 51 can be achieved only by tightening and loosening the adjusting member 52. The elastic member 54 can also achieve adaptive elastic support for the support seat 1. A relatively stable position adjustment of the loading wheel scraper 4 can be achieved without the need for additional fixing screws, and the adjustment is convenient.
