Description

Technical Field

[0001] The utility model belongs to the technical field of luggage processing, and particularly relates to a multi-station punching machine for luggage leather. Background Art

[0002] As an important material for making luggage, leather comes in various textures and thicknesses. During the production process, luggage often requires punching to facilitate the installation of accessories, decoration, or to achieve specific functional requirements.

[0003] Related art (Announcement No. CN215549251U) discloses a bag punching device, comprising a frame, a gantry frame fixed above the frame, a drilling mechanism in the middle of the gantry frame, a workbench fixed on the frame and located below the drilling mechanism, a through hole in the middle of the workbench, a bucket-shaped suction port below the through hole, a suction machine below the bucket-shaped suction port, the suction machine being arranged on the frame, a shock-absorbing pad above the workbench, a shock-absorbing spring below the shock-absorbing pad, the shock-absorbing spring being located inside the workbench, a positioning mechanism being provided above the shock-absorbing pad, the positioning mechanism comprising a moving unit and a fixed unit, which are arranged relative to each other, the moving unit comprising a telescopic cylinder fixedly connected to the shock-absorbing pad, a clamping plate provided at the output end of the telescopic cylinder, and the fixed unit comprising an L-shaped positioning plate. This improves work efficiency.

[0004] However, existing luggage leather punching equipment usually adopts a one-by-one punching method, which is inefficient and affects production progress. Punching holes one by one is not only time-consuming and labor-intensive, but also requires repositioning each time a hole is punched, making it difficult to ensure the positional accuracy between each hole. Hole position deviation is prone to occur, which in turn leads to subsequent luggage assembly being not smooth, affecting product quality. In addition, during the process of punching holes one by one, the equipment is frequently started and stopped, which increases energy consumption and equipment wear, and increases production costs.

This method is inefficient and requires repositioning each time a hole is punched, making it difficult to ensure the position accuracy between each hole. It is easy to have hole position deviation, which in turn leads to subsequent luggage assembly not being smooth, affecting product quality and other problems. The utility model provides a luggage and leather material multi-station punching machine, which can realize the synchronous punching processing of four groups of holes. Compared with the traditional method of punching holes one by one, it is more efficient and eliminates the tedious steps of repositioning each time a hole is punched. The positioning is simpler and more accurate, avoiding the hole position deviation affecting the subsequent luggage assembly effect, and can better ensure the luggage production quality. In addition, there is no need to frequently start and stop the equipment for punching holes one by one, saving energy consumption, avoiding unnecessary wear of equipment, and saving production costs. Its specific technical solution is as follows:

[0006] A multi-station punching machine for luggage leather, comprising a workbench, a support plate fixedly mounted on the workbench, a cylinder disposed on the top of the support plate, and a multi-station punching unit disposed at the output end of the cylinder;

[0007] The multi-station punching unit includes a base body installed on the output end of the cylinder, a first motor is installed on the base body, the output end of the first motor is connected to a first gear through a rotating shaft, an extension arm is fixedly installed on the bottom end of the base body, and the extension arm is provided with four free ends extending outward, and drill bits are respectively provided at the four free ends of the extension arm in the vertical direction, and each drill bit is rotatably connected to the extension arm, and a second gear is fixedly installed on each drill bit, and each second gear is meshed with the side wall of the first gear.

[0008] In the above technical solution, the four drill bits are arranged at equal distances in the circumferential direction relative to the center of the first gear.

[0009] In the above technical solution, two limit plates are provided on the workbench, and the two limit plates are symmetrically arranged front to back relative to the center of the first gear.

[0010] In the above technical solution, the two limit plates are moved relative to each other through the adjustment unit;

[0011] The adjusting unit includes a base, a second motor is installed on the front side wall of the base, the output end of the second motor is connected to one end of a screw, and the other end of the screw is rotatably connected to the side wall of the base, the screw is provided with front and rear symmetrical external threads in opposite directions, and two movable plates are threadedly sleeved on the front and rear sides of the screw, two light rods are fixedly installed in the base, and the two light rods are symmetrically arranged with respect to the screw, the movable plate is slidably sleeved on the light rod, and two connecting arms are symmetrically installed on each movable plate, and the connecting arms are fixedly connected to the limit plates at corresponding positions.

[0012] In the above technical solution, the connecting arm includes a long rod and a short rod arranged parallel to each other, a vertical rod is connected between the long rod and the short rod, and the long rod is connected to the limiting plate, and the short rod is connected to the movable plate.

[0013] In the above technical solution, a limit seat is fixedly installed at the bottom end of the workbench, and the screw rotates and passes through the inner cavity of the limit seat.

[0014] In the above technical solution, four sets of limit assemblies are installed on the side wall of the support plate;

[0015] Each group of the limiting components includes a fixing seat fixedly mounted on the side wall of the support plate. A lifting column is vertically penetrated through each of the fixing seats, and the lifting column is fixedly connected to the extension arm.

[0016] Compared with the prior art, the multi-station punching machine for luggage and leather materials of the present invention has the following beneficial effects:

[0017] First, the existing bag leather punching equipment usually adopts the method of punching holes one by one. This method is inefficient and requires repositioning each time a hole is punched, making it difficult to ensure the position accuracy between each hole. It is easy to have hole position deviation, which leads to the problem that the subsequent bag assembly is not smooth and affects the product quality. The utility model drives the four groups of drill bits in the circumferential direction to rotate synchronously by the first gear, so as to realize the synchronous punching of the four groups of holes. Compared with the traditional method of punching holes one by one, it is more efficient and eliminates the tedious steps of repositioning each time a hole is punched. The positioning is simpler and more accurate, avoiding the hole position deviation affecting the subsequent bag assembly effect, and can better ensure the bag production quality.

[0018] Second, in response to the existing method of punching holes in luggage leather materials one by one, the equipment is frequently started and stopped, which increases energy consumption and equipment wear, and increases production costs. The utility model can use the first motor to cause the first gear and the second gear to rotate synchronously, so as to achieve four sets of drill bits to punch holes synchronously. There is no need to frequently start and stop the equipment for punching holes one by one, which saves energy consumption, avoids unnecessary equipment wear, and saves production costs.

[0019] 3. The utility model can limit the position of the luggage leather material through two sets of symmetrically arranged limit plates, ensuring that the luggage leather material is properly placed relative to the four sets of drill bits. After the leather material is subsequently punched, the two sets of hole positions can be symmetrical front and back, ensuring the front and back symmetry of the hole positions when the luggage is subsequently assembled;

[0020] Fourth, the present invention can promote the relative movement of the two sets of connecting arms and the limit plates through the second motor, screw, polished rod, and movable plate, so as to adjust the distance between the two limit plates to meet the limit requirements of luggage leather materials of different widths;

[0021] In summary, the utility model can realize the synchronous punching processing of four groups of holes, which is more efficient than the traditional method of punching holes one by one, and eliminates the tedious steps of re-positioning each time a hole is punched. The positioning is simpler and more accurate, avoiding the hole position deviation affecting the subsequent luggage assembly effect, and can better ensure the luggage production quality. In addition, there is no need to frequently start and stop the equipment for punching holes one by one, which saves energy consumption, avoids unnecessary wear of the equipment, and saves production costs. It can also limit the leather materials of luggage to ensure that the leather materials of luggage are properly placed relative to the four groups of drill bits, and ensure the front-to-back symmetry of the hole positions during the subsequent assembly of the luggage after the leather materials are punched.

DETAILED DESCRIPTION

[0029] The following is a combination of specific implementation cases and attached Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0030] See Figures 1 to 6 As shown, a multi-station punching machine for luggage leather includes a workbench 1, on which holes for a drill bit to penetrate are opened, which can provide space for drilling and prevent the drill bit from damaging the workbench 1. A support plate 2 is fixedly installed on the workbench 1, and a cylinder 3 is provided on the top of the support plate 2. The output end of the cylinder 3 is provided with a multi-station punching unit. The cylinder 3 can drive the entire multi-station punching unit to move downward synchronously, so that the multi-station punching unit is close to the leather material to perform drilling processing on the leather material;

[0031] Main references Figure 3 、 Figure 4 and Figure 6As shown, the multi-station punching unit includes a base body 4 installed at the output end of the cylinder 3, a first motor 5 is installed in the base body 4, and the cylinder 3 can drive the base body 4 and the first motor 5 to move downward synchronously. The output end of the first motor 5 is connected to the first gear 7 through a rotating shaft. The turned-on first motor 5 can drive the first gear 7 to rotate. An extension arm 6 is fixedly installed at the bottom end of the base body 4, and the extension arm 6 is provided with four free ends extending outward. A drill bit 8 is respectively provided at the four free ends of the extension arm 6 in the vertical direction, and each drill bit 8 is rotatably connected to the extension arm 6 through a bearing. A second gear 9 is fixedly installed on each drill bit 8. , and each second gear 9 is meshed with the side wall of the first gear 7. The first motor 5 is turned on to drive the first gear 7 to rotate, prompting the four groups of second gears 9 meshed with the side walls of the first gear 7 to rotate synchronously. The rotation of the second gear 9 drives the drill bits 8 at their respective positions to rotate, and the drill bits 8 that rotate and gradually move downward can perform four-point synchronous punching processing on the leather; the four drill bits 8 are equidistantly arranged relative to the center of the first gear 7 in the circumferential direction, thereby ensuring that the four groups of drill bits 8 can ensure that after the subsequent punching processing of the leather, the front and rear groups of hole positions can be symmetrical front and back, ensuring the front and back symmetry of the hole positions during the subsequent assembly of the luggage.

[0032] In addition, see Figure 1 、 Figure 3 and Figure 5 As shown, two limit plates 20 are provided on the workbench 1, and the two limit plates 20 are symmetrically arranged front and back relative to the center of the first gear 7. Through the two groups of limit plates 20 symmetrically arranged front and back, the luggage leather material can be limited to ensure that the luggage leather material is properly placed relative to the four groups of drill bits 8; the two limit plates 20 are relatively moved by the adjustment unit; the adjustment unit includes a base 13, and a second motor 14 is installed on the front side wall of the base 13. The output end of the second motor 14 is connected to one end of a screw rod 15, and the other end of the screw rod 15 is rotatably connected to the side wall of the base 13. The screw 15 is provided with external threads symmetrically arranged front and back in opposite directions, and the front and rear sides of the screw 15 are respectively threaded with screw sleeves Two movable plates 18, two polished rods 17 are fixedly installed in the base 13, and the two polished rods 17 are symmetrically arranged relative to the screw 15. The movable plates 18 are slidably sleeved on the polished rods 17, and two connecting arms 19 are symmetrically installed on each movable plate 18, and the connecting arms 19 are fixedly connected to the limit plates 20 at the corresponding positions. The screw 15 is driven to rotate by the turned-on second motor 14, thereby prompting the two movable plates 18 to move synchronously toward the middle along the outer walls of the polished rod 17 and the screw 15, so as to prompt the adjustment of the distance between the front and rear sets of connecting arms 19 and the limit plates 20, so as to prompt the distance between the two limit plates 20 to meet the limit requirements of the luggage leather material being processed this time.

[0033] Specific reference Figure 5As shown, the connecting arm 19 includes a long rod and a short rod arranged parallel to each other, a vertical rod is connected between the long rod and the short rod, and the long rod is connected to the limit plate 20, and the short rod is connected to the movable plate 18, thereby ensuring that when the movable plate 18 drives the connecting arm 19 to drive the limit plate 20 to move, there is still enough distance between the connecting arm 19 and the side wall of the workbench 1 to avoid the situation where the connecting arm 19 contacts the side wall of the workbench 1 and cannot prompt the limit plate 20 to continue moving.

[0034] In addition, see Figure 4 and Figure 5 As shown, a limit seat 16 is fixedly installed at the bottom end of the workbench 1, and the screw 15 rotates and passes through the inner cavity of the limit seat 16, and the limit seat 16 can provide support for the screw 15.

[0035] In addition, the main reference Figure 1 and Figure 2 As shown, four groups of limit assemblies are installed on the side wall of the support plate 2; each group of limit assemblies includes a fixing seat 21 fixedly installed on the side wall of the support plate 2, and each fixing seat 21 is provided with a lifting column 22 running through it in the vertical direction, and the lifting column 22 is fixedly connected to the extension arm 6. When the cylinder 3 drives the seat body 4 and the extension arm 6 to rise and fall synchronously, it can prompt the lifting column 22 to move up and down along the inner cavity of the fixing seat 21, thereby limiting the lifting direction of the extension arm 6.

[0036] It is worth noting that the cylinder 3 used in this application is a self-locking cylinder commonly used on the market, and its output end can stay at any position and be locked; the first motor 5 and the second motor 14 use self-locking motors commonly used on the market with output ends that can be locked. When they stop working, their output ends can be self-locked and will not rotate under external force, and the first motor 5 and the second motor 14 are forward and reverse motors commonly used on the market, and their output ends can rotate forward or reverse according to usage requirements, and they can meet the above-mentioned usage requirements; the above-mentioned existing components will not be described in detail here.

[0037] The working principle of the multi-station punching machine for luggage leather in this embodiment is as follows:

[0038] The screw 15 is rotated by the turned-on second motor 14, which in turn causes the two movable plates 18 to move synchronously toward the middle along the outer wall of the polished rod 17 and the screw 15, thereby adjusting the distance between the front and rear connecting arms 19 and the limiting plates 20, so that the distance between the two limiting plates 20 meets the limiting requirements of the luggage leather material being processed.

[0039] Place the leather material to be processed between the two limiting plates 20 from left to right, so that the front and rear sides of the leather material are respectively in contact with the side walls of the two limiting plates 20. This allows the two limiting plates 20 to limit the position of the leather material, ensuring that the leather material is directly under the four drill bits 8.

[0040] The opened cylinder 3 causes the base body 4, the first motor 5 and the extension arm 6 to move downward synchronously, causing the drill bit 8 and the second gear 9 at the free end of the extension arm 6 to move downward, so that the drill bit 8 gradually approaches the bottom end of the luggage leather material; the opened first motor 5 drives the first gear 7 to rotate, causing the four groups of second gears 9 meshing with the side walls of the first gear 7 to rotate synchronously, and the rotation of the second gear 9 drives the drill bits 8 at their respective positions to rotate, and the drill bit 8 that rotates and gradually moves downward can perform four-point synchronous drilling processing on the leather material.

[0041] The utility model can realize the synchronous punching of four groups of holes, which is more efficient than the traditional method of punching holes one by one, and eliminates the tedious steps of re-positioning each time a hole is punched. The positioning is simpler and more accurate, and the hole position deviation is avoided from affecting the subsequent luggage assembly effect, and the luggage production quality can be guaranteed. In addition, there is no need to frequently start and stop the equipment for punching holes one by one, which saves energy consumption, avoids unnecessary wear of the equipment, and saves production costs. It can also limit the leather materials of luggage and ensure that the leather materials of luggage and bags are properly placed relative to the four groups of drill bits 8, and ensure the front-to-back symmetry of the hole positions during the subsequent assembly of the luggage after the leather materials are punched.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
