Description

Technical Field

[0001] The utility model relates to the technical field of metal can feeding equipment, in particular to a side film clamping mechanism. Background Art

[0002] During transportation, the lids of cans are generally arranged one by one into long strips, and then wrapped with film to form cylindrical strips. The wrapped strips are then stacked on pallets in sequence, and a long stretch film (also called a restraint belt) is wrapped around each layer of material to prevent the layers of material from becoming loose. After stacking multiple layers, material chops are formed. During processing, the pallet together with the material chops needs to be forked onto the lifting platform, and then the material chops are pushed from top to bottom, layer by layer, onto the conveyor belt through a pushing mechanism.

[0003] When people are loading the material strips, in order to prevent the restraint belt from sliding with the material strips, the pushing mechanism pushes the material strips while also clamping the restraint belt through the film clamping mechanism. When clamping the film, the clamping end of the film clamping mechanism needs to extend between the two bundles of material strips to clamp the restraint belt.

[0004] The traditional film clamping mechanism adopts a dual-axis linkage of a Y-axis drive mechanism and a Z-axis drive mechanism to clamp the film. Since the side of the material strip is curved, when the Z-axis drive mechanism drives the film clamping assembly to move up and down from the side of the material strip, the film clamping assembly will come into contact with the material strip and cause the film clamping assembly to generate a force in the X-axis direction. However, the traditional clamping mechanism does not have the function of fine-tuning and adapting on the X-axis, and can only push the material hard in the X-axis direction, which is also easy to affect the normal operation of the equipment. In this context, the applicant is committed to developing a side film clamping mechanism. When the Z-axis drive mechanism drives the film clamping assembly to move up and down from the side of the material strip, the film clamping assembly is micro-adjusted in the X-axis direction to avoid hard push between the film clamping assembly and the material, thereby further ensuring the normal operation of the equipment. Utility Model Content

[0005] The purpose of the utility model is to achieve micro adjustment of the film clamping assembly in the X-axis direction when the Z-axis drive mechanism drives the film clamping assembly to move up and down from the side of the material strip, thereby avoiding hard push between the film clamping assembly and the material strip, and further ensuring the normal operation of the equipment.

[0006] In order to achieve the above purpose, the technical solutions adopted by the present invention are as follows:

[0007] A side film clamping mechanism, comprising a Y-axis drive mechanism, an X-axis fine-tuning mechanism, a Z-axis drive mechanism and a film clamping assembly;

[0008] The X-axis fine-tuning mechanism includes a movable table, a first slide rail, a first slide plate, a first tension spring, and a second tension spring. The Y-axis driving mechanism drives the movable table to move back and forth along the Y-axis direction. The first slide rail is fixedly arranged on the movable table along the X-axis direction. The first slide plate is slidably arranged on the first slide rail. The first tension spring and the second tension spring pull the first slide plate in the positive and negative directions of the X-axis respectively. The Z-axis driving mechanism is fixedly connected to the first slide plate, and the Z-axis driving mechanism cooperates with the clamping assembly.

[0009] Furthermore, the Y-axis driving mechanism includes a second cylinder and a second slide rail. The second slide rail is arranged along the Y-axis direction. The movable platform is slid on the second slide rail. The second cylinder drives the movable platform to slide back and forth along the second slide rail.

[0010] Furthermore, the mobile platform includes a first plate, a second plate, a hinge and a fixed block, the first plate is slid on the second slide rail, the first plate and the second plate are hinged to each other by a hinge, and the fixed block is fixed to the first plate and the second plate at the same time by screws.

[0011] Furthermore, the X-axis fine-tuning mechanism also includes a fixing pin, a first fixing pin, and a second fixing pin. The fixing pin is fixedly arranged on the first slide plate, the first fixing pin and the second fixing pin are both fixed on the second plate, and the first fixing pin and the second fixing pin are respectively located on both sides of the fixing pin. The two ends of the first tension spring are respectively fixed on the first fixing pin and the fixing pin, and the two ends of the second tension spring are respectively fixed on the second fixing pin and the fixing pin.

[0012] Furthermore, the clamping assembly includes a clamping plate and a clamping rod, the clamping plate is fixedly arranged on the Z-axis driving mechanism, the Z-axis driving mechanism drives the clamping rod to move back and forth along the Z-axis, and the clamping plate and the clamping rod cooperate with each other to clamp.

[0013] Furthermore, the film clamping rod is arranged along the Y-axis direction, and the head end of the film clamping rod is pointed.

[0014] Furthermore, it also includes a fixing frame, and the Y-axis driving mechanism is fixedly arranged on the fixing frame.

[0015] The beneficial effects of the present invention are as follows: the present invention slides the first slide onto the first slide rail, and pulls the first slide in the positive and negative directions of the X-axis respectively through the first tension spring and the second tension spring, so that as long as a certain external force is applied to the first slide, the first slide can be moved back and forth a certain distance in the direction of the X-axis. When the Z-axis driving mechanism drives the film clamping assembly to move up and down from the side of the material strip, the side of the material strip is curved, which causes the film clamping assembly to generate a force on the X-axis, and the film clamping assembly drives the first slide to move along the first slide rail, so that the film clamping assembly has a certain left and right fine-tuning amplitude in the X-axis direction, realizing micro-adjustment in the X-axis direction, thereby avoiding hard push between the film clamping assembly and the material chop, and further ensuring the normal operation of the equipment.

[0023] The present invention will be further described below with reference to the accompanying drawings. It should be noted that the directions of the X-axis, Y-axis, and Z-axis are in the Figure 2 Clearly marked in.

[0024] like Figures 1 to 3 The side film clamping mechanism shown includes a fixing frame 1, a Y-axis driving mechanism 2, an X-axis fine-tuning mechanism 3, a Z-axis driving mechanism 4 and a film clamping assembly 5.

[0025] The X-axis fine-tuning mechanism 3 includes a movable table 31, a first slide rail 32, a first slide plate 33, a first tension spring 34, a second tension spring 35, a fixing pin 36, a first fixing nail 37, and a second fixing nail 38. The Y-axis driving mechanism 2 drives the movable table 31 to move back and forth along the Y-axis direction. The first slide rail 32 is fixedly set on the movable table 31 along the X-axis direction, and the first slide plate 33 is slidably set on the first slide rail 32.

[0026] The first tension spring 34 and the second tension spring 35 pull the first slide plate 33 in the positive and negative directions of the X-axis respectively. In this embodiment, a more specific structure is as follows: the fixing pin 36 is fixedly provided on the first slide plate 33, the first fixing pin 37 and the second fixing pin 38 are both fixed on the second plate 312, and the first fixing pin 37 and the second fixing pin are respectively located on both sides of the fixing pin 36, the two ends of the first tension spring 34 are respectively fixed on the first fixing pin 37 and the fixing pin 36, and the two ends of the second tension spring 35 are respectively fixed on the second fixing pin 38 and the fixing pin 36, so that the first slide plate 33 is located in the middle position of the first slide rail 32, so that as long as a certain external force is applied to the first slide plate 33, the first slide plate 33 can be moved back and forth a certain distance in the direction of the X-axis, so that the film clamping assembly 5 has a certain left and right fine-tuning range in the X-axis direction, realizing micro-adjustment in the X-axis direction.

[0027] The Y-axis driving mechanism 2 is fixedly disposed on the fixing frame 1 , the Z-axis driving mechanism 4 is fixedly connected to the first slide 33 , and the Z-axis driving mechanism 4 cooperates with the film clamping assembly 5 .

[0028] The Y-axis driving mechanism 2 includes a second cylinder 21 and a second slide rail 22 . The second slide rail 22 is arranged along the Y-axis direction. The movable platform 31 is slidably arranged on the second slide rail 22 . The second cylinder 21 drives the movable platform 31 to slide back and forth along the second slide rail 22 .

[0029] The movable platform 31 includes a first plate 311, a second plate 312, a hinge 313 and a fixed block 314. The first plate 311 is slidably arranged on the second slide rail 22. The first plate 311 and the second plate 312 are hinged to each other by the hinge 313. The fixed block 314 is fixed to the first plate 311 and the second plate 312 at the same time by screws.

[0030] The hinge 313 and the fixing block 314 are designed to enable the membrane assembly 5 to clamp the restraint belt 6 in both horizontal and vertical directions. The specific operation method is to first remove the fixing plate, and then rotate the second plate 312 with the hinge 313 as the center, so that the second plate 312 and the first plate 311 are ninety degrees or one hundred and eighty degrees according to actual needs, and then fix the fixing block 314 on the first plate 311 and the second plate 312 at the same time with screws, so that the first plate 311 and the second plate 312 are relatively fixed.

[0031] The clamping assembly 5 includes a clamping plate 51 and a clamping rod 52. The clamping plate 51 is fixedly arranged on the Z-axis driving mechanism 4. The Z-axis driving mechanism 4 drives the clamping rod 52 to move back and forth along the Z axis. The clamping plate 51 and the clamping rod 52 cooperate with each other to clamp.

[0032] The film clamping rod 52 is disposed along the Y-axis direction, and the head end of the film clamping rod 52 is pointed.

[0033] The working principle of the present invention is as follows: when the restraint belt 6 needs to be fixed, the Z-axis driving mechanism 4 first drives the film clamping rod 52 downward to separate the film clamping rod 52 and the film clamping plate 51 from each other, and then the Y-axis driving mechanism 2 drives the film clamping assembly 5 to move, and moves the film clamping rod 52 to the bottom of the restraint belt 6, and makes the restraint belt 6 located between the film clamping plate 51 and the film clamping rod 52, and then the Z-axis driving mechanism 4 drives the film clamping rod 52 to retract, and clamps the restraint belt 6 between the film clamping rod 52 and the film clamping plate 51 to prevent the restraint belt 6 from sliding while pushing the material strip 7.

[0034] When the Z-axis drive mechanism 4 drives the film clamping rod 52 to retract, the film clamping rod 52 may move upward close to the side of the material strip 7. Since the side of the material strip 7 is an outwardly protruding arc surface, when the film clamping rod 52 moves upward close to the side of the material strip 7, it will produce displacement in the direction of the X-axis. At this time, the film clamping assembly 5 drives the first slide 33 to move along the first slide rail 32, so that the film clamping assembly 5 has a certain left and right fine-tuning range in the X-axis direction, realizing micro-adjustment in the X-axis direction, thereby avoiding hard push between the film clamping assembly 5 and the material strip 7, and further ensuring the normal operation of the equipment.

[0035] The above disclosure is only a preferred embodiment of the present invention and cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention. The above does not impose any limitation on the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
