Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to tableware spraying equipment and a rotating fixing fixture thereof. Background Art

[0002] When spraying tableware with the prior art, it is necessary to use a clamp to fix the tableware. In order to facilitate spraying, the tableware needs to be rotated. The spacing between the tableware causes waste of paint and pollutes the environment. In addition, the existing clamp is relatively cumbersome when fixing the tableware, and cannot adapt well to tableware of multiple sizes and the inner walls of tableware with different inclination angles. Summary of the invention

[0003] The present invention provides tableware spraying equipment and a rotating fixing fixture thereof, which can conveniently fix tableware of various sizes and with different inner wall inclination angles, and can avoid scratches on the inner wall of the tableware, thereby improving production efficiency.

[0004] In order to solve the above technical problems, the present invention is solved by the following technical solutions: A rotating fixing clamp comprises a supporting column, a clamping portion is provided on the upper part of the supporting column, and a plurality of clamping components are provided on the outer side surface of the clamping portion along the circumference of the supporting column, the clamping components comprise a clamping piece, an extending block, a rotating block and a clamping spring; the clamping spring is arranged on the inner side of the clamping piece, and the two ends of the clamping spring are respectively clamped against the inner wall of the clamping portion and the inner end of the clamping piece; the extending block is arranged on the outer side of the clamping piece; the rotating block is arranged on the outer side of the extending block, and a clamping surface contacting with the object is provided on the rotating block.

[0005] When in use, the tableware can be fixed on the supporting column through the clamping component, wherein the clamping spring pushes the clamping component outward so that the clamping component always tends to press against the inner wall of the tableware; the clamping surface is close to the inner wall of the tableware, and the clamping surface is provided with anti-slip grooves, which can prevent the tableware from sliding relative to the rotating fixing clamp, increase the stability of the fixed tableware, and facilitate the use of the rotating fixing clamp to rotate the tableware.

[0006] Preferably, a movable ring which can slide along the axial direction of the support column is provided on the support column, a plurality of first limiting blocks are provided on the inner side of the movable ring, and a plurality of first limiting grooves cooperating with the first limiting blocks are provided on the support column.

[0007] The first limiting groove is arranged along the axial direction of the support column, and the first limiting block slides in the first limiting groove along the axial direction of the support column, so that the movable ring can slide up and down along the support column. In the invention, the first limiting groove and the first limiting block are arranged below the tightening part. When the rotating fixing clamp is used to fix the tableware, the tableware opening faces downward, and the staff can directly change the position of the movable ring on the support column by manipulating the movable ring.

[0008] Preferably, a first protrusion is provided on the movable ring, a second protrusion is provided at the lower part of the abutting member, and a connecting member is provided between the first protrusion and the second protrusion.

[0009] Through the first protrusion, the second protrusion and the connecting piece, when the position of the moving ring on the support column is changed, as the moving ring slides up and down on the support column, the clamping piece approaches or moves away from the support column: when the moving ring moves downward, the clamping piece is pulled close to the support column, and the clamping spring is compressed, so the clamping radius of the rotating fixing clamp is reduced, thereby facilitating the staff to fix the tableware on the rotating fixing clamp or remove the tableware by pulling the moving ring downward; when the moving ring moves upward, the clamping piece moves away from the support column, so the clamping radius of the rotating fixing clamp increases, so that after the staff releases the moving ring, the clamping spring pushes the clamping piece away from the support column, and the moving ring is driven to move upward, and at this time the clamping surface presses against the inner wall of the tableware to fix the tableware.

[0010] Preferably, the extending block is provided with a plurality of positioning holes for adjusting the length of the extending block extending beyond the abutting piece, and the abutting piece is provided with positioning portions corresponding to the positioning holes.

[0011] To ensure stability, the positioning holes are optionally arranged in pairs on the protruding block. The protruding block can be pulled out of or inserted into the abutting piece, and the length of the entire abutting assembly can be changed by changing the protruding length of the protruding block relative to the abutting piece, thereby expanding the adjustment range of the abutting radius of the rotating fixing fixture to adapt to tableware of different sizes and increase the applicable range of the rotating fixing fixture.

[0012] Preferably, a rotating portion is provided at the connection between the rotating block and the extending block.

[0013] By rotating the rotating block, the rotating block can be rotated around the rotating part relative to the extending block, thereby adjusting the inclination angle of the abutting surface to adapt to different inclination angles of the inner wall of the tableware, so that the abutting surface fits the inner wall of the tableware more closely to prevent damage to the tableware. Optionally, the abutting surface is set to rubber or other materials with a certain elasticity, so as to ensure that the abutting component can abut the tableware and prevent the inner wall of the tableware from being scratched.

[0014] Preferably, a fixing component is provided on the left and right sides of the extending block, and two ends of the fixing component are respectively connected to the rotating part and the positioning part.

[0015] The rotating part is used to fix the rotating angle of the rotating block, and the positioning part is used to fix the extending length of the extending block relative to the clamping member. The fixing assembly is used to simultaneously fix the rotating angle of the rotating block and the extending length of the extending block relative to the clamping member. On the basis of ensuring the stability of the rotating fixing clamp in fixing tableware, the structure is simplified and the service life of the rotating fixing clamp is extended.

[0016] Preferably, the fixing assembly comprises a first fixing member and a second fixing member, the first fixing member can slide along the length direction of the second fixing member, the first fixing member is used to connect the rotating part, and the second fixing member is used to connect the positioning part.

[0017] Through the relative sliding of the first fixing member and the second fixing member, the length of the fixing assembly can be adjusted to adapt to different extension lengths of the extension block: when the extension length of the extension block relative to the clamping member increases, the fixing assembly also becomes longer; when the extension length of the extension block relative to the clamping member decreases, the fixing assembly also becomes shorter.

[0018] Preferably, a rotation positioning portion is provided on the first fixing member, and a rotation positioning groove cooperating with the rotation positioning portion is provided on the rotating block at the rotating portion.

[0019] A plurality of rotation limiting grooves are provided in the rotation positioning groove along the circumferential direction, and a plurality of rotation limiting protrusions are provided on the surface of the rotation positioning part along the circumferential direction. The rotation limiting grooves correspond to the rotation limiting protrusions. After determining the inclination angle of the rotating block, the rotation positioning part is placed in the rotation positioning groove to limit the rotation of the rotating block, thereby fixing the rotation angle of the rotating block.

[0020] Preferably, a positioning bolt for connecting the protruding block and the abutting member is provided in cooperation with the positioning hole on the second fixing member.

[0021] An extension limit groove for the extension block to move is provided in the tightening member. The extension block moves in the extension limit groove. When the extension block is moved to a suitable extension length, a positioning bolt is inserted into the positioning portion and the corresponding positioning hole to fix the extension length of the extension block.

[0022] Preferably, a second limiting block for connecting a limiting spring is provided at one inner end of the clamping member, a second limiting groove is provided in the clamping portion to cooperate with the second limiting block, and both ends of the clamping spring are respectively clamped against the second limiting block and the bottom surface of the second limiting groove.

[0023] Through the second limiting groove, the second limiting block of the clamping member slides along the second limiting groove in the clamping part, thereby increasing the stability of the clamping spring during the expansion and contraction process and the overall stability of the clamping assembly.

[0024] A tableware spraying device comprises any one of the above-mentioned rotating fixed fixtures and a movable spraying pump, wherein there are two rotating fixed fixtures.

[0025] When spraying the tableware, the tableware is clamped and fixed by a rotating fixing fixture, and the mobile spray pump can move with the tableware to spray; after the mobile spray pump moves and sprays the tableware fixed on the first rotating fixing fixture for a certain period of time, it moves and sprays the tableware fixed on the second rotating fixing fixture, and the mobile spray pump moves alternately to the first rotating fixing fixture and the second rotating fixing fixture to spray, and the spraying work is repeated.

[0029] When in use, the tableware can be fixed on the support column 00 through the clamping component 110, wherein the clamping spring 270 pushes the clamping component 110 outward so that the clamping component 110 always has a tendency to press against the inner wall of the tableware; the clamping surface 231 is close to the inner wall of the tableware, and the clamping surface 231 is provided with anti-slip grooves, which can prevent the tableware from sliding relative to the rotating fixing clamp, increase the stability of the fixed tableware, and facilitate the use of the rotating fixing clamp to rotate the tableware.

[0030] In this embodiment, a movable ring 130 that can slide along the axial direction of the support column 00 is provided on the support column 00, a plurality of first limit blocks 610 are provided on the inner side of the movable ring 130, and a plurality of first limit grooves 140 are provided on the support column 00 to cooperate with the first limit blocks 610.

[0031] The first limiting groove 140 is arranged axially along the support column 00, and the first limiting block 610 slides in the first limiting groove 140 along the axial direction of the support column 00, so that the movable ring 130 can slide up and down along the support column 00. In this embodiment, the first limiting groove 140 and the first limiting block 610 are arranged below the tightening portion 100. When the tableware is fixed by using the rotating fixing clamp, the tableware opening faces downward, and the staff can directly change the position of the movable ring 130 on the support column 00 by manipulating the movable ring 130.
