Description

TECHNICAL FIELD

[0001] The present application relates to the field of material distribution mechanism, in particular to a barrel separating and feeding mechanism. BACKGROUND

[0002] In pad printing technology, a part of the workpieces to be printed is in the shape of a barrel. In order to facilitate storage, the barrel workpieces to be printed and the completed printed barrel workpieces are stacked. Although such a storage method can greatly save space, the layer-by-layer stacking of the barrel workpieces can form a negative pressure cavity between the barrel workpieces.

[0003] Due to the large depth of the barrel workpieces, the negative pressure cavity formed after the two barrel workpieces are stacked is larger. A large pulling force is required to separate the stacked barrel workpieces. Generally, after the barrel workpieces are separated, the barrel workpieces are loaded into a printing mold. The existing barrel separating mechanism separates the barrel workpieces by pushing the front barrel with a push rod after fixing the rear barrel, and then directly pushes the front barrel into the printing mold with the push rod. Since the above barrel separating method forcibly overcomes the large negative pressure suction force between the barrels, the push rod needs to provide a large pushing force. The large negative pressure suction force and pushing force not only easily damage the separated front barrel, but also make the front barrel have a large kinetic energy when it is separated, which affects the stability of the barrel entering posture, i.e., the front barrel is easily deviated, which affects the accuracy of the relative position between the barrel and the printing mold, resulting in low barrel entering efficiency and large load.

[0047] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the described embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

The terms "first", "second" and similar words used in the present application do not represent any order, number or importance, but are only used to distinguish different components. Similarly, "one" or "a" and similar words do not represent a quantity limit, but represent the existence of at least one.

"Up", "down", "left", "right" and the like are only used to represent relative positional relationships, and when the absolute positions of the described objects are changed, the relative positional relationships are also changed accordingly.

[0049] The embodiments of the present application will be described in detail below with reference to the drawings.

[0050] Reference Figures 1-4As shown, the embodiment of the present application provides a barrel feeding mechanism, which comprises an entering barrel assembly 100 and a barrel separating assembly 200. The entering barrel assembly 100 comprises a guide bracket 110 for guiding the transmission direction of the barrel 40. The barrel separating assembly 200 comprises a barrel separating wheel unit 210 and a power source unit 220. The barrel separating wheel unit 210 is in transmission connection with the power source unit 220. The surface of the barrel separating wheel unit 210 is provided with a threaded groove 2101.

[0051] The barrel 40 has a raised edge 41 on the outer surface of the barrel 40 body. The edge 41 is in contact with the threaded groove 2101. In this solution, the barrel separating wheel unit 210 rotates. The edge 41 of the barrel 40 is located in the threaded groove 2101. The barrel 40 is limited in the moving direction by the guide bracket 110, so that the barrel 40 moves along a straight transmission direction S. The transmission direction S is specifically the axial direction of the barrel separating wheel unit 210.

[0052] In this solution, the thread pitch of the threaded groove 2101 gradually increases. Specifically, the thread pitch of the threaded groove 2101 gradually increases along the transmission direction S, so that the moving distance of the barrel 40 per unit time gradually increases. The groove width of the threaded groove 2101 is consistent, so as to ensure that the edge 41 is in the threaded groove 2101 and drives the barrel 40. Since the thread pitch of the threaded groove 2101 gradually increases and the groove width of the threaded groove 2101 is constant, the width of the thread 2102 gradually increases. In this solution, the thread pitch of the threaded groove 2101 increases proportionally, and the width of the thread 2102 increases proportionally. In the straight direction parallel to the axis of the barrel separating wheel unit 210, the width of the thread 2102 proportionally increases L1, L2, L3…L. n The function formula used in the above proportionality can be a linear function, an exponential function and a power function.

[0053] In the process of transmitting the barrel 40, in order to reduce the storage space of the barrel 40, the barrel 40 is generally stored in a stacking manner. However, due to the characteristics of the barrel 40, the depth of the barrel 40 is large. After the barrel 40 is stacked, a negative pressure cavity will be formed between the adjacent two barrels 40. When the barrel separating wheel unit 210 drives the barrel 40 to move, the distance between the adjacent two barrels 40 gradually increases, the negative pressure suction force generated by the negative pressure cavity is decomposed multiple times, the load required during barrel separation is reduced, and the stability of the barrel feeding posture is ensured.

[0054] Further, the bucket wheel unit 210 comprises a first threaded bucket wheel 211 and a second threaded bucket wheel 212, and the bucket 40 is clamped between the first threaded bucket wheel 211 and the second threaded bucket wheel 212. The threaded grooves 2101 of the first threaded bucket wheel 211 and the second threaded bucket wheel 212 are symmetrically arranged, and the rotation directions of the first threaded bucket wheel 211 and the second threaded bucket wheel 212 are opposite. In the present scheme, the first threaded bucket wheel 211 and the second threaded bucket wheel 212 are driven by the same power source unit 220. The rotation directions of the first threaded bucket wheel 211 and the second threaded bucket wheel 212 are towards the bucket 40 located between the two. Specifically, the first threaded bucket wheel 211 is located on the left side of the bucket 40, the second threaded bucket wheel 212 is located on the right side of the bucket 40, and the first threaded bucket wheel 211 rotates clockwise, the second threaded bucket wheel 212 rotates counterclockwise, and the guide bracket 110 is located below the bucket 40, so that the guide bracket 110 blocks the bucket 40 in the vertical direction. In the present specific scheme, under the driving of the first threaded bucket wheel 211 and the second threaded bucket wheel 212, the bucket 40 has a downward movement tendency, and due to the limitation of the vertical position by the guide bracket 110, the first threaded bucket wheel 211 and the second threaded bucket wheel 212 can finally drive the bucket 40 to move along the transmission direction S while also being able to press the bucket 40 on the guide bracket 110, preventing the bucket 40 from deviating from the space between the first threaded bucket wheel 211, the second threaded bucket wheel 212 and the guide bracket 110.

[0055] In the present scheme, the two ends of the bucket wheel unit 210 are respectively an initial end 2103 and a terminal end 2104, and the thread groove 2101 close to the initial end 2103 has a smaller thread pitch length than the thread groove 2101 close to the terminal end 2104. Wherein, the guide bracket 110 extends along the direction from the terminal end 2104 to the initial end 2103, and the guide bracket 110 finally extends outward from the initial end 2103. The part of the guide bracket 110 extending out of the initial end 2103 is the loading position, and the stacked bucket 40 enters the bucket wheel unit 210 from the loading position.

[0056] Further, the number of guide brackets 110 is two, and the two guide brackets 110 are arranged in parallel. The bucket 40 is supported on the two guide brackets 110. Wherein, the bucket 40 further comprises a handle 42, and the two ends of the handle 42 are rotatably connected to the edge portion 41. And under the driving of the first threaded bucket wheel 211 and the second threaded bucket wheel 212, the two ends of the handle 42 are pressed on the two guide brackets 110.

[0057] In some embodiments of the present application, reference is made to Figure 5As shown, the bucket separating assembly 200 further comprises a positioning unit 230 arranged close to the initial end 2103, which is capable of connecting with the handle 42 and driving the handle 42 to rotate relative to the body of the bucket 40.

[0058] Specifically, the positioning unit 230 comprises a cylinder 231, a first rotating base 232, a stopper 233 and a first elastic member 234. The first rotating base 232 is connected to the power output end of the cylinder 231 and is driven by the cylinder 231 to move in the transmission direction. The first rotating base 232 is rotationally connected to the stopper 233, and the first elastic member 234 is connected between the first rotating base 232 and the stopper 233. The stopper 233 is in contact with the handle 42.

[0059] More specifically, the first rotating base 232 is rotationally connected to the stopper 233, which comprises that the stopper 233 is L-shaped, one end of the stopper 233 is connected to the first rotating base 232 through a first rotating shaft 235, so that the stopper 233 can rotate relative to the first rotating base 232, and the other end of the stopper 233 is located on the moving path of the bucket 40. Due to the restriction of the first elastic member 234, the stopper 233 can rotate relative to the first rotating base 232 in one direction.

[0060] The cylinder 231 drives the first rotating base 232 and the stopper 233 to move towards the initial end 2103, and in the moving process, the stopper 233 is in contact with the handle 42. As the stopper 233 moves towards the stacked bucket 40, the stopper 233 rotates relative to the first rotating base 232, and the first elastic member 234 is elastically deformed. After the stopper 233 passes the handle 42 of the bucket 40 closest to the stopper 233, the stopper 233 is elastically restored to its original position by the first elastic member 234, the cylinder 231 reverses its movement to drive the first rotating base 232 and the stopper 233 to retreat, the stopper 233 contacts the handle 42 and drives the handle 42 to rotate relative to the body of the bucket 40, so that the handle 42 is separated from the adjacent bucket 40 in the stacked bucket 40, thereby avoiding the problem that the separation of two buckets 40 is difficult due to the restriction of the handle 42 during the separation of the buckets.

[0061] During the separation of the buckets, the handle 42 is easily connected with the edge 41 of the adjacent bucket 40, and during the separation, the handle 42 pulls the adjacent bucket 40 to move, resulting in a large difficulty in separating the adjacent two buckets 40 and affecting the separation effect. In the present scheme, the positioning unit 230 is arranged to separate the handle 42 from the edge 41 of the adjacent bucket 40, thereby avoiding the driving of the adjacent bucket 40 during separation.

[0062] Further, the positioning unit 230 further comprises a first limiting rod 236 and a fixing rod 237, the first limiting rod 236 is installed on the stopper 233, the fixing rod 237 is installed on the first rotating base 232, the first limiting rod 236 and the fixing rod 237 are located on the same side of the positioning unit 230, and the two ends of the first elastic member 234 are connected to the first limiting rod 236 and the fixing rod 237 respectively. When the stopper 233 rotates relative to the first rotating base 232, the distance between the first limiting rod 236 and the fixing rod 237 changes, and the first elastic member 234 connected to the first limiting rod 236 and the fixing rod 237 is stretched to produce elastic deformation.

[0063] Further, the positioning unit 230 further comprises an adjusting bracket 238 and a movable bracket 239, the air cylinder 231 is slidingly connected to the movable bracket 239, the first rotating base 232 is installed on the adjusting bracket 238, and the adjusting bracket 238 is slidingly connected to the power output end of the air cylinder 231.

[0064] The air cylinder 231 can slide relative to the movable bracket 239 along a first linear direction S1, the adjusting bracket 238 and the first rotating base 232 can slide relative to the power output end of the air cylinder 231 along a second linear direction S2, and the first linear direction S1, the second linear direction S2 and the transmission direction S are perpendicular to each other. The movable bracket 239 is installed on the fixed seat of the barrel feeding mechanism. Through the adjusting bracket 238 and the movable bracket 239, the stopper 233 can move relative to the barrel 40 along the first linear direction S1 and the second linear direction S2, so as to adjust the relative position of the stopper 233 and the barrel 40.

[0065] In some embodiments of the present application, as shown in Figure 6 The barrel feeding mechanism further comprises a barrel pushing assembly 300, which is arranged on one side of the barrel dividing wheel unit 210 close to the terminal end 2104. The barrel pushing assembly 300 comprises a linear driving unit 310 and a barrel pushing clamp unit 320, and the barrel pushing clamp unit 320 is installed on the power output end of the linear driving unit 310.

[0066] Under the driving of the driving unit 310, the barrel pushing clamp unit 320 is driven to move from one end of the driving unit 310 to the other end of the driving unit 310, and the barrel pushing clamp unit 320 can reciprocate between the two ends of the driving unit 310. One end of the driving unit 310 is located at the terminal end 2104, so that the barrel 40 that completes the barrel dividing at the terminal end 2104 is pushed to the other end of the driving unit 310 through the barrel pushing clamp unit 320. In the present scheme, the number of barrel pushing assemblies 300 is two, and the two barrel pushing assemblies 300 are symmetrically arranged.

[0067] More specifically, the pushing barrel clamping unit 320 comprises a rotating pushing clamp 321, a second rotating base 322, a buffer 323 and a second elastic member 324. The rotating pushing clamp 321 is rotationally connected with the second rotating base 322, and the second elastic member 324 is connected between the rotating pushing clamp 321 and the second rotating base 322. In the present scheme, the structure of the pushing barrel clamping unit 320 is similar to that of the positioning unit 230. The rotating pushing clamp 321 can rotate in one direction relative to the second rotating base 322, can pass over the edge 41 of the barrel 40, and can contact the edge 41 to drive the single barrel 40 to move along the track of the driving unit 310.

[0068] Further, the rotating pushing clamp 321 has a frustum on the side thereof facing the other pushing barrel assembly 300, the frustum has a slope surface facing the terminal end 2104 and a mounting surface opposite to the slope surface, the buffer 323 is connected to the mounting surface, and an included angle between the slope surface and the mounting surface is an acute angle. When the edge 41 moves on the slope surface, the rotating pushing clamp 321 is driven to rotate.

[0069] Still further, the pushing barrel assembly 300 further comprises a pushing rod unit 330, and the pushing rod unit 330 and the pushing barrel clamping unit 320 are installed on the same power output end of the linear driving unit 310. Specifically, the pushing rod unit 330 and the pushing barrel clamping unit 320 are installed on the same bracket, and the bracket is connected to the power output end of the linear driving unit 310. The pushing rod unit 330 and the pushing barrel clamping unit 320 are arranged in an up-down manner, the pushing rod unit 330 contacts the handle 42 to drive the handle 42 to rotate relative to the barrel body 40, so as to ensure the posture of the barrel 40.

[0070] The above embodiments are used to further illustrate the present application, but do not limit the present application to these specific embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be understood as within the protection scope of the present application.
