DETAILED DESCRIPTION

[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other unless they conflict. For the convenience of description, the words "upper", "lower", "left", and "right" appearing below only indicate the upper, lower, left, and right directions consistent with the drawings themselves and do not limit the structure.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Examples, such as Figures 1-11As shown, the present invention provides a watch strap grinding device with an automatic loading function, comprising a grinding tool 1 and an arranging tool 2 for arranging and placing multiple watch straps at the same time, wherein the arranging tool 2 is a partial annular structure and a plurality of arranging grooves 21 cooperating with the watch straps are provided on the outer surface of the arranging tool 2, there are two arranging tools 2 and they are arranged on the tool rotating shaft 3 at intervals in a clockwise direction, and the tool rotating shaft 3 is provided with two chip removal tools 4 cooperating with the arranging tool 2 at intervals, and four groups of clamping tools 5 are provided between the inner side of the arranging tool 2 and the tool rotating shaft 3, wherein the clamping ends of two groups of clamping tools 5 are used to clamp the head end of the watch strap, and the clamping ends of the other two groups of clamping tools 5 are used to clamp the tail end of the watch strap, and the clamping tools 5 are provided at the inner side of the arranging tool 2 and the tool rotating shaft 3. The driving end of the device 5 is provided with an electromagnetic component 6 located in the center of the tooling shaft 3, and a feed box 7 is provided on one side of the tooling shaft 3. A plurality of feed chutes 71 are provided on the feed box 7. The feed chute 71 extends from top to bottom and corresponds to the curved surface of the arrangement groove 21. The feed box 7 is provided with a plurality of feed conveyor belts 8 corresponding to the feed chutes 71 on the side facing away from the arrangement tooling 2. A grinder box 9 is provided on the other side of the tooling shaft 3. The grinder box 9 is provided with a first grinding shaft 91 and a second grinding shaft 92 which are spaced apart and staggered in an upper and lower manner. The grinding tools 1 are arranged axially at intervals on the first grinding shaft 91 and the second grinding shaft 92, and the grinder box 9 is provided with a plurality of grinding ports 93 corresponding to the grinding tools 1.

[0033] Specifically, the grinding tool 1 adopts a polishing grinding wheel / pulley; the wheel surface of the grinding tool 1 contacts the watch strap and completes the grinding by generating relative rotational motion; adjacent feed conveyor belts 8 are separated by spacer square tubes to ensure the orderliness of single-row watch strap transmission; the turning positions of all feed conveyor belts 8 are transmitted through a set of transmission roller groups, and the transmission rollers are driven by a reduction motor to make the feed conveyor belt 8 form a continuous transmission action; the first grinding shaft 91 and the second grinding shaft 92 can be driven by the same power mechanism, or by different power mechanisms respectively. The first grinding shaft 91 and the second grinding shaft 92 can adjust the grinding feed amount by adjusting the actual distance between them and the arrangement tooling 2. From the perspective of the grinding operation principle of this equipment, the feed conveyor belt 8 can convey the flat watchband to the feed chute 71, and the watchband falls on the arranging tool 2. The gravity and inertia of the watchband can make it stick to the surface of the arranging groove 21, and by properly controlling the counterclockwise and clockwise fine-tuning of the tool shaft 3, the watchband can be better placed in the arranging groove 21; the clamping tool 5 is driven by the electromagnetic component 6, and the clamping tool 5 clamps the ejector pin 55 and the pressure block 56 at the head and tail ends of the watchband respectively. The tool shaft 3 and the grinding tool 1 are driven by their respective power sources to make relative rotational motion, so that the watchband can be automatically polished, with good maneuverability, and the watchband passes through the grinding tool 1 twice in the same rotation direction. In addition, the watchband is exposed under the grinding working surface in a bent manner, and the probability of contact between the surface to be ground and the grinding tool 1 is increased, which is beneficial to improving the overall processing efficiency of the watchband surface.

[0034] Furthermore, if the watch straps arranged on one arranging fixture 2 form a row, the present device can grind a single row of watch straps. If watch straps are arranged on two arranging fixtures 2, the present device can also grind both rows simultaneously. The grinding machine housing provided by the present invention has substantially the same shape as the facing surfaces of the feed box 7, including at least a curved surface structure that matches the outer circumference of the arranging fixture 2, with the length of the curved surface structure being greater than the length of the curved surface segment 73 of the feed box 7. In this way, when arranging the watch straps to be polished on two arranging tools 2, the arranging slots 21 on one arranging tool 2 are first filled with watch straps, and then the other arranging tool 2 is rotated clockwise at a certain angle to face the feed chute 71, and all the clamping tools 5 can release the clamping action. For the arranging tool 2 that is already full of watch straps, the watch straps are supported by the curved surface of the grinder box 9 and the grinding tool 1, so that the watch straps always remain in the state of being attached to the arranging slots 21; after the other arranging tool 2 is also full of watch straps, the electromagnetic component 6 controls the clamping tool 5 to complete the positioning of all watch straps. Therefore, the tool shaft 3 can carry two rows of watch straps to complete the polishing, which is beneficial to improving the working capacity of this equipment.

[0035] like Figure 2 As shown, to facilitate automatic unloading, the feed box 7 provided by the present invention includes a vertical section 72 and a curved section 73 on the side facing the arrangement tool 2. The curved section 73 corresponds to the curved surface of the arrangement tool 2, and the vertical projection width of the curved section 73 is less than the radius of the arrangement tool 2. The vertical section 72 and the curved section 73 match the surface of the arrangement tool 2, so that the watch straps do not interfere with each other in the arrangement slot 21, effectively separating watch straps from different rows. Furthermore, the bottom of the curved section 73 can serve as a discharge port after the clamping tool 5 is released. During the rotation of the tool shaft 3, the centrifugal force can discharge the watch strap from the end position of the curved section 73, thereby achieving the purpose of automatic unloading.

[0036] To improve the efficiency of the watchband dropping from the feed chute 71 into the arrangement slot 21, the feed chute 71 provided by the present invention is provided with an arc-shaped dispensing spring 74. The top end of the dispensing spring 74 is a fixed end, and the bottom end of the dispensing spring 74 is a free end. Under the action of gravity and inertia, the watchband enters between the dispensing spring 74 and the arrangement slot 21. The dispensing spring 74 uses its elasticity to press the end of the watchband, on the one hand, effectively lowering the end of the watchband to the end of the arrangement slot 21, and on the other hand, uses its elastic body to arch the watchband toward the head end of the arrangement slot 21, causing the top end of the watchband to tend to abut against the head end of the arrangement slot 21 until the watchband abuts against the head end of the arrangement slot 21. This improves the coordination between the watchband and the arrangement slot 21, and helps to improve the clamping efficiency of the ejector pin 55 and the pressure block 56 on the watchband.

[0037] In order to improve the clamping efficiency of the clamping tool 5, the clamping tool 5 provided by the present invention includes a left clamping plate 51 and a right clamping plate 52 that are axially movable and plug-in compatible. The left clamping plate 51 and the right clamping plate 52 are provided with multiple pairs of left sliders 53 and right sliders 54 that are matched in pairs. The left slider 53 and the right slider 54 used to clamp the head end of the watch strap are both provided with ejector pins 55, and the ejector pins 55 on the left slider 53 and the ejector pins 55 on the right slider 54 are distributed facing each other. The left slider 53 and the right slider 54 used to clamp the tail end of the watch strap are both provided with pressure blocks 56, and the pressure blocks 56 on the left slider 53 and the pressure blocks 56 on the right slider 54 are distributed facing each other. Among them, all the left sliders 53 on the same clamping tool 5 are installed on the same left clamping plate 51, so they can be moved to the right synchronously. Similarly, the right sliders 54 on the same clamping tool 5 are installed on the same right clamping plate 52, so they can be moved to the left synchronously; the ejectors 55 on the same level are paired to form a pair of clamping needles, and the ejectors 55 are used to connect with the pin holes and pin tubes at the head end of the strap; the pressure blocks 56 on the same level are paired to form a pair of clamping blocks, which are used to clamp the tail end edge position of the strap, thereby ensuring the coordination effect between the strap and the clamping tool 5.

[0038] Furthermore, the left splint 51 provided by the present invention includes an inverted T-shaped left bottom plate section 511, a left vertical plate section 512 is provided on the left bottom plate section 511, the left vertical plate section 512 is slidably matched with the through-port provided on the arrangement tooling 2, and a left connecting tube 513 is provided at one end of the bottom of the left bottom plate section 511; the right splint 52 includes a U-shaped right bottom plate section 521, the right bottom plate section 521 is movably connected to the left bottom plate section 511, an n-type section 522 is provided on the right bottom plate section 521, a right vertical plate section 523 is provided on the n-type section 522, and a right connecting tube 524 is provided at the bottom of the right vertical plate section 523. The U-shaped opening of the right bottom plate section 521 provides a certain amount of translational margin for the left vertical plate section 512. The n-shaped section 522 creates a certain opening for the left bottom plate section 511, which has a certain thickness. The bottom surface of the left bottom plate section 511 can be attached to the right bottom plate section 521 for relative translational movement. The left connecting tube 513 maintains a certain safe distance from the end of the right clamping plate 52, and the right connecting tube 524 also maintains a certain safe distance from the end of the left clamping plate 51. Therefore, the left connecting tube 513 and the right connecting tube 524 do not affect the real-time movement of the left clamping plate 51 and the right clamping plate 52. Furthermore, the left and right sliders 53 and 54 are equipped with fins that slide with the arrangement tool 2 to ensure the translational stability of the left and right sliders 53 and 54. The ends of the left connecting tube 513 and the right connecting tube 524 can be slidably matched with the tenons on the inner end surface of the arranging tooling 2, further improving the clamping accuracy of the clamping end of the clamping tooling 5; at the same time, the left connecting tube 513 and the right connecting tube 524 also provide a connection basis for the clamping transmission rod 57, thereby providing functional support for the electromagnetic component 6 to input clamping power to the clamping tooling 5.

[0039] In order to improve the arrangement effect of the watch strap in this device, the arrangement tool 2 provided by the present invention has a sufficient diameter, leaving enough length for the arrangement slot 21 to accommodate the watch strap, and the interior of the arrangement tool 2 is a hollow design to reduce the rotation of the tool shaft 3. Considering that the left clamping plate 51 and the right clamping plate 52 need to be arranged close to the inner wall of the arrangement tool 2, and the electromagnetic assembly 6 is based on the assembly of the tool shaft 3, the bottom of the left clamping plate 51 and the right clamping plate 52 provided by the present invention are both provided with a clamping transmission rod 57, which is Z-shaped and connected to the electromagnetic assembly 6. By utilizing the direction turning and radial extension of the clamping transmission rod 57, the left clamping plate 51 and the right clamping plate 52 can reasonably establish a transmission path with the electromagnetic assembly 6, and a set of electromagnetic assemblies 6 can simultaneously drive four sets of clamping tools 5, which is conducive to improving the clamping synchronization of all watch straps of this device.

[0040] like Figure 4 、 Figure 7 and Figure 8 As shown, in order to improve the driving performance of the electromagnetic component 6 on the clamping tooling 5, the electromagnetic component 6 provided by the present invention includes a guide box 61, two guide blocks 62 are provided in the guide box 61, each guide block 62 is simultaneously connected to the transmission ends of the two clamping toolings 5, and the side of the guide block 62 is provided with an armature 63 located on the outside of the guide box 61, the tooling shaft 3 is provided with a mounting groove 31, and an I-shaped iron core 64 is provided in the mounting groove 31. The ribs of the iron core 64 are used to wind the coil 65 and a pair of cylindrical magnetic suction ports 66 are provided at both ends thereof, and the cylindrical magnetic suction ports 66 are used to magnetically cooperate with the iron core 64. The coil 65 is connected to a power source via a wire running through the interior of the fixture shaft 3. The power source can be a battery-powered portable power source or a fixed power source in the workshop. When the coil 65 is energized, the iron core 64 generates a magnetic attraction, thereby attracting the armature 63 toward the cylindrical magnetic port 66. The two armatures 63 on the same side move in opposite directions, thereby driving the clamping rods in different directions to move in opposite directions, such as the left clamping plate 51 moving right and the right clamping plate 52 moving left, thereby enabling the clamping fixture 5 to achieve its clamping function. When the coil 65 is de-energized, the elastic restoring force of the reset spring 68 resets the clamping transmission rod 57, causing the ejector pin 55 and the pressure block 56 to release the watchband, thereby releasing the clamping relationship. This electromagnetic assembly 6 is rationally designed, has a good synchronous drive effect, and is highly space-efficient.

[0041] To improve the reliability of the electromagnetic assembly 6, the present invention provides two positioning posts 67 at the bottom of the guide box 61, connected to the tool shaft 3. A return spring 68 is provided between the positioning posts 67 and the armature 63. The positioning posts 67 are connected to the tool shaft 3 via axial bolts, and the tool shaft 3 is provided with a strip groove 32 that slides with the armature 63. This provides a stable assembly relationship between the positioning posts 67 and the tool shaft 3, maintaining a fixed angle after assembly. Therefore, the movement path of the guide block 62 and the guide box 61 is fixed, thereby ensuring the stability of the relative movement between the left and right clamping plates 51 and 52. At the same time, the tool shaft 3 and the armature 63 establish a translational sliding path through the strip groove 32. The groove surface of the strip groove 32 has a C-shaped structure, which can effectively position and guide the armature 63, thereby improving the immediacy and linearity of the armature 63's movement.

[0042] In order to improve the assembly performance of the arranging tooling 2 and the chip removal tooling 4, the two ends of the arranging tooling 2 provided by the present invention are provided with assembly openings 22, and the two ends of the chip removal tooling 4 are provided with protrusions 41 that cooperate with the assembly openings. The outer side of the assembly opening 22 is provided with a fastening bolt connecting the arranging tooling 2 and the chip removal tooling 4. A circumferential positioning relationship can be established through the assembly opening 22 and the protrusion 41, and the axial movement amount is effectively controlled, which is beneficial to improving the synchronous movement performance of the chip removal tooling 4, the arranging tooling 2 and the tooling shaft 3.

[0043] like Figure 4 、 Figure 9 and Figure 11 As shown, for easy maintenance, the chip removal fixture 4 provided by the present invention is radially oriented toward the electromagnetic assembly 6. The central angle of the chip removal fixture 4 is greater than 15 degrees. By removing one chip removal fixture 4, the structural space inside the arrangement fixture 2 can be opened, so that the clamping fixture 5 and the electromagnetic assembly 6 are within a certain exposure range, which is convenient for daily maintenance. Furthermore, to improve the chip removal effect, the chip removal fixture 4 is provided with a circumferential notch 42 corresponding to the arrangement groove 21 and an axial notch 43 along with all the circumferential notches 42. The grinding chips generated during the grinding process can enter the axial notch 43 from the circumferential notch 42, facilitating centralized processing and discharge, and avoiding accumulation in the arrangement groove 21 and affecting the real-time grinding quality.

[0044] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
