Description

Technical Field

[0001] The present application relates to the field of packaging equipment, and in particular to a bagging device for spray can lids. Background Art

[0002] As packaging containers for gaseous products, spray cans are widely used in food, cosmetics, medicine, and other fields. The spray can consists of three parts: the body, the bottom, and the lid, of which the lid is usually conical.

[0003] In the related art, when the can lids of spray cans are produced, the sheet material must first be punched into shape by a punching device, and then sent to a testing device for testing to remove defective products. After the testing is completed, it is sent to a cleaning device for cleaning to remove dirt adhering to the can lids during the production process. The cleaned can lids will be further dried by a drying device, and finally the dried can lids will be stacked and conveyed by a can lid conveying device, and the stacked can lids will be manually transferred into a cylindrical paper bag to facilitate the movement of the can lids.

[0004] With regard to the above-mentioned related technologies, the bagging operation of can lids is currently mainly done manually. On the one hand, the operation efficiency is low. On the other hand, during the bagging process, it is very easy to cause the can lids that were originally stacked intact to scatter, which makes the operation more inconvenient. Therefore, there is room for improvement. Summary of the Invention

[0005] In order to facilitate the can caps conveyed by the can cap conveying equipment to be packed into the paper belt, the present application provides a spray can cap bagging device.

[0006] The present application provides a spray can lid bagging device, which adopts the following technical solution: A spray can lid bagging device comprises a frame on which an arc-shaped trough and a lid pushing assembly are arranged; The two ends of the arc-shaped trough are respectively a feeding end and a discharging end, and the feeding end of the arc-shaped trough is connected to the output end of the can cover conveying equipment to receive the can cover outputted from the output end of the can cover conveying equipment; The push-cover assembly is used to drive the can cover located in the arc-shaped material trough to move toward the discharge end of the arc-shaped material trough; the push-cover assembly includes a push-cover part and a first sliding drive component, and the first sliding drive component is used to drive the push-cover part to move back and forth along the arc-shaped material trough; the push-cover part is located above the arc-shaped material trough, and the push-cover part includes a push-cover bracket, and the push-cover bracket is provided with a push-cover plate and a first lifting drive component, and the first lifting drive component is used to drive the push-cover plate to move up and down.

[0007] By adopting the above technical solution, when bagging the can lids, the paper bag is sleeved in advance at the discharge end of the arc-shaped chute. After a certain number of can lids are input into the arc-shaped chute through the output end of the can lid conveying device and accumulated, the first sliding drive member of the lid pushing assembly cooperates with the first lifting drive member of the lid pushing portion to drive the push cover plate to be stuck into the gap between adjacent can lids, and drive the push cover plate to move towards the discharge end of the arc-shaped chute, so as to push the stack of can lids into the paper bag, completing the operation of bagging the can lids. Compared with the traditional operation of bagging can lids manually, the overall operation process does not require manual intervention, effectively improving the bagging efficiency of can lids.

[0008] Preferably, a lid blocking assembly is further provided on the frame. The lid blocking assembly includes a lid blocking portion and a second sliding drive member. The second sliding drive member is used to drive the lid blocking portion to reciprocate along the arc-shaped chute. The lid blocking portion is located above the arc-shaped chute. The lid blocking portion includes a lid blocking bracket, and the lid blocking bracket is provided with a lid blocking plate and a second lifting drive member. The second lifting drive member is used to drive the lid blocking plate to move up and down.

[0009] By adopting the above technical solution, when the lid pushing assembly moves the stack of can lids on the arc-shaped chute towards the discharge end of the arc-shaped chute, the second sliding drive member cooperates with the second lifting drive member to drive the lid blocking plate to block the front end of the remaining stack of can lids in the arc-shaped chute at this time, and drive the baffle plate to move towards the storage end of the arc-shaped chute along with the stack of can lids. Using the lid blocking plate to limit the front end of the remaining stack of can lids is beneficial to restricting the can lids at the front end of the can lid end from being toppled and scattered due to the impact of the newly introduced can lids into the arc-shaped chute, facilitating the stack of can lids in the arc-shaped chute to better maintain an upright state, so as to facilitate the subsequent loading of the neatly stacked can lids into the paper bag.

[0010] Preferably, a connecting pipe is coaxially sleeved at the discharge end of the arc-shaped chute, and the connecting pipe is used for sleeving the end of the paper bag.

[0011] By adopting the above technical solution, when bagging the can lids, the port of the paper bag is sleeved on the outer periphery of the connecting pipe. Using the connecting pipe to support and limit the port of the paper bag is beneficial to keeping the port of the paper bag always open, facilitating the subsequent stack of can lids to better move into the paper bag.

[0012] Preferably, a bag clamping portion is further provided at the connecting pipe. The bag clamping portion includes two bag clamping cylinders. The two bag clamping cylinders are located on opposite sides of the connecting pipe, and the bag clamping cylinders are both arranged towards the connecting pipe.

[0013] By adopting the above technical solution, the paper bag is sleeved on the outer periphery of the connecting pipe, and the clamping cylinders on the opposite sides of the connecting pipe clamp and fix the end of the paper bag to realize the limit fixation of the paper bag, so as to limit the paper bag from being separated from the connecting pipe when the subsequent lid-pushing mechanism pushes the stack of can lids on the arc-shaped chute into the paper bag, which is beneficial for the lid-pushing assembly to push the can lids into the paper bag.

[0014] Preferably, the frame is further provided with a top cover assembly. The top cover assembly includes a top cover bracket, and the top cover bracket is supported above the arc-shaped chute through a connecting bracket and is arranged near the discharge end of the arc-shaped chute; the connecting bracket is further provided with a third lifting driving member for driving the top cover bracket to lift vertically; a top cover cylinder is arranged on the top cover bracket, the top cover cylinder is arranged parallel to the arc-shaped chute, and the top cover cylinder is arranged towards the discharge end of the arc-shaped chute, and the piston rod of the top cover cylinder is connected with a top cover head.

[0015] By adopting the above technical solution, when the lid-pushing assembly pushes the stack of can lids into the paper bag, due to the existence of the connecting pipe, the lid-pushing assembly cannot completely push the can lids into the paper bag, and it is easy to leave some can lids in the connecting pipe; through the setting of the top cover assembly, when the lid-pushing assembly completes the lid-pushing operation and moves back to the reset position, the third lifting driving member drives the top cover bracket to drive the top cover cylinder to move down into the arc-shaped groove, and the top cover cylinder drives the top cover head to further move towards the paper bag direction until the stack of can lids in the connecting pipe is pushed into the paper bag.

[0016] Preferably, the piston rods of the clamping cylinders are all connected with flexible blocks, and an arc-shaped surface is formed on one side of the flexible blocks facing the connecting pipe, and the contour of the arc-shaped surface is adapted to the contour of the connecting pipe.

[0017] By adopting the above technical solution, on the one hand, the setting of the flexible blocks is beneficial to reducing the damage to the paper bag caused by clamping and fixing the paper bag through the two clamping cylinders, and on the other hand, it is beneficial to increasing the friction between the piston rods of the clamping cylinders and the paper bag through the flexible blocks, so that the two clamping cylinders can more firmly clamp and fix the paper bag.

[0018] Preferably, an arc-shaped support groove is further arranged on the frame, and the arc-shaped support groove is opposite to the connecting pipe, and the arc-shaped support groove is used for the paper bag to be embedded.

[0019] By adopting the above technical solution, through the setting of the arc-shaped support groove, when installing the paper bag, the paper bag is placed in the arc-shaped support groove. When the subsequent lid-pushing mechanism pushes the can lids into the paper bag, the arc-shaped support groove can assist in supporting the can lids pushed into the paper bag, which is beneficial to limiting the situation that the can lids loaded into the paper bag drag the socket end of the paper bag.

[0020] Preferably, the end of the connecting pipe away from the arc-shaped chute is sharp.

[0021] By adopting the above technical solution, by making the end of the connecting pipe sharp, it is beneficial to guide the paper bag through the sharp end of the connecting pipe, and then it is convenient to put the paper bag onto the connecting pipe.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: The following beneficial technical effects: 1. Through the setting of the arc-shaped material trough and the push cover assembly, after the arc-shaped material trough receives a certain number of can lids output by the can lid conveying device, the first sliding drive member at the push cover assembly cooperates with the first lifting drive member of the push cover part to drive the push cover plate to be clamped into the gap between adjacent can lid plates and move towards the discharge end of the arc-shaped material trough, so as to push the stack of can lids into the paper bag pre-sleeved at the discharge end of the arc-shaped material trough, completing the automatic bagging of the can lids and effectively improving the bagging efficiency of the can lids.

[0023] 2. Through the setting of the baffle cover assembly, while the push cover assembly pushes the can lids into the paper bag, the second sliding drive member of the baffle cover assembly cooperates with the second lifting drive member of the baffle cover part to drive the baffle cover plate to block the front end of the remaining stack of can lids in the arc-shaped material trough, and drive the baffle cover plate to move along the arc-shaped material trough together with the newly introduced stack of can lids, so as to realize the limit of the stack of can lids and prevent the can lids at the front end of the stack of can lids from scattering during the movement.

[0031] The following further elaborates on this application in conjunction with the Figures 1-5 accompanying drawings.

[0032] An embodiment of this application discloses a device for bagging the lid of a spray can. Referring to Figure 1 and Figure 2 , it includes a frame 1. An arc-shaped material chute 2 and a push cover assembly 3 are arranged on the frame 1. The two ends of the arc-shaped material chute 2 are respectively a feeding end and a discharging end. The feeding end of the arc-shaped material chute 2 is connected to the output end of the can lid conveying device, and is used to receive the can lids transmitted from the output end of the can lid conveying device. The push cover assembly 3 is used to drive the stack of can lids input into the arc-shaped material chute 2 by the can lid conveying device to move towards the discharging end of the arc-shaped material chute 2.

[0033] The bottom of the arc-shaped material chute 2 is connected with a base, and the base is welded to the top of the workbench, so as to stably install the arc-shaped material chute 2 on the workbench. A connecting pipe 20 is connected to the discharging end of the arc-shaped material chute 2. The inner cavity of the connecting pipe 20 is communicated with the arc-shaped material chute 2, and is used to receive the can lids output from the output end of the arc-shaped material chute 2. The connecting pipe 20 is used for the end of the paper bag to be sleeved. When bagging the can lids, the end of the paper bag can be sleeved on the outer periphery of the connecting pipe 20, and the connecting pipe 20 is used to expand the end of the paper bag, so that the can lids pushed out from the discharging end of the arc-shaped material chute 2 by the push cover assembly 3 can better enter the paper bag subsequently. The end of the connecting pipe 20 away from the arc-shaped material chute 2 is provided with a sharp tip, and the sharp tip of the connecting pipe 20 is used to guide the paper bag, making it easier for the paper bag to be sleeved on the outer periphery of the connecting pipe 20.

[0034] Referring to Figure 1 and Figure 2, a bag clamping part 21 is also arranged at the connecting pipe 20. The bag clamping part 21 includes two bag clamping cylinders 212. The two bag clamping cylinders 212 are both supported on the machine frame 1 through bag clamping brackets 211. The two bag clamping cylinders 212 are respectively located on opposite sides of the connecting pipe 20 and both face the connecting pipe 20. The ends of the piston rods of the bag clamping cylinders 212 are both connected with flexible blocks 213. In this embodiment, the flexible blocks 213 are rubber blocks. An arc surface is formed on the side of the flexible block 213 facing the connecting pipe 20, and the contour of the arc surface is adapted to the outer contour of the connecting pipe 20.

[0035] After the end of the paper bag is sleeved on the outer periphery of the connecting pipe 20, the flexible blocks 213 at the ends of the piston rods of the two bag clamping cylinders 212 are driven to abut against the outer periphery of the paper bag, so as to press the paper bag on the connecting pipe 20, realizing the limit of the end of the paper bag, and restricting the situation that the end of the paper bag is separated from the connecting pipe 20 due to the force on the paper bag after the subsequent push cover assembly 3 pushes the can lid into the paper bag.

[0036] The arrangement of the flexible blocks 213 at the ends of the piston rods of the bag clamping cylinders 212 is beneficial to restricting the bag clamping cylinders 212 from clamping and damaging the paper bag on the one hand, and on the other hand, is beneficial to increasing the friction force between the bag clamping cylinders 212 and the paper bag, facilitating the two bag clamping cylinders 212 to clamp the paper bag on the connecting pipe 20 more firmly.

[0037] Refer to Figure 1 and Figure 2 , an arc-shaped support groove 11 is also installed on the machine frame 1. The arc-shaped support groove 11 is located at one end of the connecting pipe 20 away from the arc-shaped material groove 2, and there is a gap between the end of the arc-shaped support groove 11 and the connecting pipe 20. The arc-shaped support groove 11 is used for placing the paper bag. When the end of the paper bag is sleeved on the connecting pipe 20 subsequently, the paper bag is placed in the arc-shaped support groove 11. After the push cover assembly 3 pushes the can lid into the paper bag, the arc-shaped support groove 11 can be used to assist in supporting the can lid in the paper bag, so as to restrict the situation that the can lid pushed into the paper bag by the push cover assembly 3 drags the port of the paper bag sleeved on the outer periphery.

[0038] Refer to Figure 1 and Figure 3The cover push assembly 3 includes a cover push portion 31 and a first sliding drive. The cover push portion 31 is positioned above the arc-shaped trough 2. The cover push portion 31 includes a cover push bracket 311, on which is mounted a cover push plate 312 and a first lifting drive. The first lifting drive is used to vertically lift the cover push plate 312. Specifically, the first lifting drive includes a first lifting cylinder 313 mounted on the cover push bracket 311. The first lifting cylinder 313 is vertically downwardly positioned. The cover push plate 312 is mounted at the bottom of the piston rod of the first lifting cylinder 313. The bottom of the cover push plate 312 has an arc-shaped notch 3121 for the cover to be inserted into. The first sliding drive component includes a first electric slide 32, which is located on one side of the arc-shaped material trough 2, and the first electric slide 32 is arranged parallel to the arc-shaped material trough 2. The push cover bracket 311 of the push cover part 31 is connected to the slider of the first electric slide 32, and the first electric slide 32 is used to drive the push cover part 31 to move back and forth along the arc-shaped material trough 2.

[0039] Reference Figure 3 and Figure 4 When the can lids on the arc-shaped trough 2 are pushed into the paper bag through the cover-pushing assembly 3, the first electric slide 32 cooperates with the first lifting cylinder 313 of the cover-pushing part 31 to drive the cover-pushing plate 312 to pass through the arc-shaped notch 3121 and fit into the gap between adjacent can lids. Then, the first electric slide 32 drives the cover-pushing part 31 to move as a whole toward the discharge end of the arc-shaped trough 2 to push the can lid stack on the arc-shaped trough 2 into the inside of the paper bag.

[0040] Reference Figure 3 and Figure 5 The frame 1 is also provided with a cover assembly 4, which includes a cover portion 41 and a second sliding drive. The cover portion 41 is located directly above the arc-shaped trough 2, and the cover portion 41 is located on the side of the push cover portion 31 away from the discharge end of the arc-shaped trough 2. The cover portion 41 includes a cover bracket 411, on which a cover plate 412 and a second lifting drive are provided. The second lifting drive is used to drive the cover plate 412 to rise and fall vertically. Specifically, the second lifting drive includes a second lifting cylinder 413 installed between the covers, and the second lifting cylinder 413 is arranged vertically downward. The cover plate 412 is connected to the bottom of the piston rod of the second lifting cylinder 413. The second sliding drive component includes a second electric slide 42, which is located on the other side of the arc-shaped material trough 2, and the second electric slide 42 is arranged parallel to the arc-shaped material trough 2. The cover bracket 411 of the cover part 41 is connected to the slider of the second electric slide 42, and the second electric slide 42 is used to drive the push cover part 31 to move back and forth along the arc-shaped material trough 2.

[0041] When the first electric slide 32 of the push cover assembly 3 cooperates with the first lifting cylinder 313 of the push cover part 31 to drive the push cover plate 312 to push the can lids located on the arc-shaped chute 2 into the paper bag, the second electric slide 42 of the baffle cover assembly 4 cooperates with the second lifting cylinder 413 of the baffle cover part 41 to drive the baffle cover plate 412 to move and block the front end of the remaining stack of can lids on the arc-shaped chute 2 at this time, and drives the baffle cover plate 412 to move together with the irrigation cans continuously input into the arc-shaped chute 2 towards the discharge end of the arc-shaped chute 2. The baffle cover plate 412 is used to limit the can lids at the front end of the stack of can lids on the arc-shaped chute 2, so as to prevent the can lids at the front end of the stack of can lids from being impacted by the newly input can lids at the rear end and falling down and scattering.

[0042] Referring to Figure 2 and Figure 5 As shown in, the machine frame 1 is further provided with a top cover assembly 5. The top cover assembly 5 is arranged near the discharge end of the arc-shaped chute 2. The top cover assembly 5 includes a top cover support 51. The top cover support 51 is supported above the arc-shaped chute 2 through a connecting support 50, and the top cover support 51 is higher than the push cover part 31 and the baffle cover part 41. A third lifting driving member for driving the top cover support 51 to lift vertically is further arranged on the connecting support 50. In this embodiment, the third lifting driving member includes a third lifting cylinder 52. The third lifting cylinder 52 is installed on the support frame body, and the third lifting cylinder 52 is arranged vertically downward. The top cover frame body is installed at the bottom of the piston rod of the third lifting cylinder 52. A top cover cylinder 511 is installed at the bottom of the top cover frame body. The length direction of the top cover cylinder 511 is parallel to the length direction of the arc-shaped chute 2, and the top cover cylinder 511 is arranged towards the discharge end of the arc-shaped chute 2. A top cover head 512 is installed at the end of the piston rod of the top cover cylinder 511.

[0043] When the push cover assembly 3 pushes the stack of can lids on the arc-shaped chute 2 into the paper bag and drives the push cover part 31 to move backward and reset away from the discharge end of the arc-shaped chute 2, the third lifting cylinder 52 of the top cover assembly 5 is used to drive the top cover support 51 to move downward until the top cover cylinder 511 at the bottom of the top cover support 51 is located in the arc-shaped chute 2. The top cover cylinder 511 is used to drive the top cover head 512 to move towards the discharge end of the arc-shaped chute 2, so as to push the can lids located in the connecting pipe 20 into the paper bag, and prevent the situation that the integrity of the can lid bagging is affected due to some can lids remaining in the connecting pipe 20.
