The moving racks on the two moving arc plates are both meshed with the rotating gear.

[0014] Preferably, the method for using a resin barrel stacking machine for producing unsaturated polyester resin includes the following steps:

[0015] S1: When clamping the outer wall of the resin barrel, the two moving arc plates move relative to each other. When the two moving arc plates move, the side brackets at the outermost end will be driven to deflect along the arc of the arc-shaped groove. At this time, the two side brackets move towards the outer wall of the resin barrel within the clamping area, enabling several side brackets to clamp the resin barrel within the clamping area in a surrounding manner;

[0016] S2: When the two moving arc plates move relative to each other and several side brackets approach the outer wall of the resin barrel, the contact plate on the side bracket at the outermost end will abut against the outer wall of the resin barrel. The inclined surface at the bottom of the contact plate will squeeze the clamping plate, and the clamping plate will move towards the connecting plate. The hinge brackets on the outer wall of the connecting column will move, causing the friction plate to expand outward and closely fit the outer wall of the resin barrel under the restriction of the moving groove on the connecting plate;

[0017] S3: When the resin barrel is released, at this time, several side brackets and the central bracket return to the same axis again. The conveyor belt adheres to the outer wall of the resin barrel in a parallel state, and the conveyor belt is located outside the moving arc plate. The servo motor drives the driving roller to rotate, and the resin barrel attached to the conveyor belt can be driven by the conveyor belt to move and be transported towards the stacking rack;

[0018] S4: When performing a clamping operation on the resin barrel, after the resin barrel is located within the clamping area, it can be driven by the pushing electric cylinder to move the support frame towards the resin barrel, so that the conveyor belt on the support frame can closely adhere to the outer wall of the resin barrel;

[0019] S5: When one moving arc plate moves, the moving rack will drive the rotating gear to rotate, and then drive the other moving rack to move the other moving arc plate. The two moving arc plates move relative to each other to perform the clamping operation on the resin barrel within the clamping area.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] In the present invention, several side brackets can perform a surrounding clamping operation on the resin barrel within the clamping area. The outer wall of the resin barrel is cylindrical. By surrounding the outer wall of the resin barrel, it can effectively fit with the outer wall of the resin barrel, making the resin barrel more stable during the clamping and transportation process.

[0022] In the present invention, the friction plate expands outward under the restriction of the moving groove on the connecting plate and closely fits against the outer wall of the resin barrel. The outer wall of the resin barrel is surrounded by a number of side brackets, and the conveyor belt wraps around the resin barrel to protect the outer wall of the resin barrel, preventing the outer wall of the resin barrel from being damaged during handling and clamping, which may cause deformation of the barrel body. Moreover, the auxiliary support members are arranged oppositely. Thus, when the friction plate surrounds the outer wall of the resin barrel, a clamping force is relatively provided to the outer wall of the resin barrel, which can concentrate the force on the required local area and reduce the contact and damage to the surfaces of other non-processing or non-operating areas of the barrel body.

[0023] In the present invention, the servo motor drives the driving roller to rotate. Driven by the adjusting roller and the conveying roller, the conveyor belt moves. The resin barrel attached to the conveyor belt can move and be conveyed in the direction of the palletizing rack under the drive of the conveyor belt, thereby realizing the palletizing operation of the resin barrel. The conveyor belt provided can convey and move the resin barrels palletized on the palletizing rack. When the resin barrel is placed on the palletizing rack, adjusting the position of the resin barrel can prevent the next resin barrel from contacting the resin barrel below during palletizing after clamping, improving the palletizing efficiency for the operator in subsequent palletizing of the resin barrels.

Specific embodiments

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a resin barrel palletizer for the production of unsaturated polyester resin, including a palletizing rack 1, a lead screw slide 11 is fixedly arranged on the top of the palletizing rack 1, a transport rack 12 is fixedly connected to the slide of the lead screw slide 11, a palletizing device 2 for clamping resin barrels is correspondingly arranged on the transport rack 12, and a clamping area 13 for placing resin barrels is formed between the two palletizing devices 2;

[0039] On the inner wall of the transport rack 12, there are support rods 14 fixedly connected correspondingly. Each of the two palletizing devices 2 includes a support frame 21 slidably arranged on the support rod 14. On the inner wall of the support frame 21, there is a clamping and conveying member 3. On both sides of the clamping and conveying member 3 on the support frame 21, there are moving arc plates 22 respectively. The two moving arc plates 22 are arranged oppositely, and arc-shaped grooves 23 are formed on both of the two moving arc plates 22. The two ends of the clamping and conveying member 3 are respectively in transmission cooperation with the two arc-shaped grooves 23.

[0040] In this embodiment, the clamping and conveying member 3 includes a central support 31 fixedly connected to the inner wall of the support frame 21. On both side walls of the central support 31, a number of side supports 32 are sequentially connected. And between the adjacent side supports 32 and the central support 31, there are hinge fits. On the side supports 32 at the outermost ends on both sides of the central support 31, there are connecting rods 33 fixedly connected. The two connecting rods 33 respectively extend into the arc-shaped grooves 23 on the two moving arc plates 22;

[0041] At the top of the support frame 21, there is a servo motor 34 fixedly connected. On the main shaft of the servo motor 34, there is a driving roller 35 in transmission connection. On both sides of the driving roller 35 on the side wall of the support frame 21, there are driven rollers 36 rotatably arranged. On the central support 31 and a number of side supports 32, there are conveying rods 37 rotatably arranged. On each conveying rod 37, there is a conveying roller 38 axially connected. On one of the outermost side supports 32, there is also a conveyor belt tensioning member 5. A conveyor belt 39 is sleeved on the driving roller 35, the driven rollers 36, the conveyor belt tensioning member 5 and a number of conveying rollers 38;

[0042] The resin barrel is located in the clamping area 13 between the two palletizing devices 2. A number of side supports 32 and the central support 31 are on the same axis. The conveyor belt 39 is horizontally arranged. When clamping the outer wall of the resin barrel, through the relative movement of the two moving arc plates 22, when the two moving arc plates 22 move, they will drive the outermost side support 32 to deflect along the radian of the arc-shaped groove 23 through the arc-shaped groove 23. At this time, the two side supports 32 will move towards the outer wall of the resin barrel in the clamping area 13 under the drive of the arc-shaped groove 23. Since a number of side supports 32 are hinged to each other, a number of side supports 32 can perform a hugging clamping operation on the resin barrel in the clamping area 13. The outer wall of the resin barrel is cylindrical. By hugging the outer wall of the resin barrel, it can effectively fit with the outer wall of the resin barrel, making the resin barrel more stable during the clamping and transportation process.

[0043] In this embodiment, auxiliary support members 4 are provided on the two side brackets 32 at the outermost ends. The auxiliary support member 4 includes a connection disk 41 fixedly connected to the conveying rod 37. A connection column 42 is sleeved on the conveying rod 37. A plurality of hinge brackets 43 are hingedly arranged around the circumference of the connection column 42 on the outer wall of the connection column 42. Moving grooves 44 corresponding to the plurality of hinge brackets 43 are formed in the connection disk 41. A friction plate 45 is slidably arranged in the moving groove 44. The inner wall of the friction plate 45 is hingedly engaged with the corresponding hinge bracket 43.

[0044] A connection spring 46 is also sleeved on the conveying rod 37. Two ends of the connection spring 46 are respectively connected to the connection disk 41 and the connection column 42. An annular groove is formed on the outer wall of the connection column 42. A clamping plate 47 is slidably arranged on the outer wall of the side bracket 32 along the axis of the conveying rod 37. The clamping plate 47 is rotatably connected to the annular groove. A resisting plate 48 perpendicular to the axis of the conveying rod 37 is arranged on the outer wall of the side bracket 32. The resisting plate 48 is slidably engaged with the side bracket 32. An elastic telescopic rod 410 is also connected between the resisting plate 48 and the side bracket 32. The bottom of the resisting plate 48 is inclined with an inclined surface 49, and the inclined surface 49 abuts against the top surface of the clamping plate 47.

[0045] When the two moving arc plates 22 move relative to each other to make the plurality of side brackets 32 approach the outer wall of the resin barrel, the resisting plate 48 drives the initial position of the resisting plate 48 to be larger than the diameter of the connection disk 41 under the drive of the elastic telescopic rod 410. The resisting plate 48 on the side bracket 32 at the outermost end will abut against the outer wall of the resin barrel. When the resisting plate 48 is subjected to pressure, the resisting plate 48 will contract and move towards the inside of the side bracket 32. At this time, the inclined surface 49 at the bottom of the resisting plate 48 will squeeze the clamping plate 47. Since the clamping plate 47 is slidably arranged on the side bracket 32 along the axis of the conveying rod 37, when the clamping plate 47 is squeezed by the inclined surface 49, the clamping plate 47 will move towards the direction of the connection disk 41. The clamping plate 47 is rotatably connected to the annular groove on the connection column 42. At this time, the connection column 42 sleeved on the conveying rod 37 will move downward towards the connection disk 41. The hinge brackets 43 arranged on the outer wall of the connection column 42 will move. Furthermore, the friction plate 45 will expand outwards and closely fit against the outer wall of the resin barrel under the limitation of the moving groove 44 on the connection disk 41. The outer wall of the resin barrel is surrounded by the plurality of side brackets 32 and the conveyor belt 39 is wrapped around the resin barrel to protect the outer wall of the resin barrel, avoiding damage to the outer wall of the resin barrel during the handling and clamping process, resulting in deformation of the barrel body. Moreover, the auxiliary support members 4 are arranged oppositely. Therefore, when the friction plate 45 surrounds the outer wall of the resin barrel, the clamping force provided relatively to the outer wall of the resin barrel can concentrate the force on the required local area, reducing the contact and damage to the surfaces of other non-processing or non-operating areas of the barrel body.

[0046] In this embodiment, the conveyor belt tensioning member 5 includes a fixed frame 51 fixedly connected to the side bracket 32. An adjusting plate 52 is slidably disposed on the fixed frame 51 correspondingly. Adjusting rods 53 are fixedly connected to both adjusting plates 52, and the adjusting rods 53 are slidably engaged with the fixed frame 51. Pressure springs 54 are sleeved on both adjusting rods 53, and both ends of the pressure springs 54 are connected to the adjusting plate 52 and the fixed frame 51 respectively. An adjusting roller 55 is rotatably connected to both adjusting plates 52;

[0047] When several side brackets 32 are driven by the moving arc plate 22 to clamp towards the outer wall of the resin barrel in the clamping area 13, the conveyor rollers 38, the driven rollers 36, the driving roller 35 and the adjusting roller 55 on the side brackets 32 will drive the conveyor belt 39 to surround towards the outer wall of the resin barrel. The conveyor belt 39 is sleeved on the adjusting roller 55. The adjusting roller 55 can adjust the position of the adjusting roller 55 under the drive of the pressure spring 54 to change the tension of the conveyor belt 39, so as to avoid the situation of jamming when the conveyor belt 39 surrounds the outer wall of the resin barrel. When the screw slide 11 drives the transport rack 12 to move downwards and stacks the clamped resin barrel onto the external pallet rack 1, the two relatively moving moving arc plates 22 move away from each other and release the resin barrel. At this time, several side brackets 32 and the central bracket 31 return to the same axis again. The conveyor belt 39 adheres to the outer wall of the resin barrel in a parallel state, and the conveyor belt 39 is located outside the moving arc plate 22. The servo motor 34 drives the driving roller 35 to rotate, and drives the conveyor belt 39 to move under the drive of the adjusting roller 55 and the conveyor rollers 38. The resin barrel attached to the conveyor belt 39 can move and be conveyed towards the direction of the pallet rack 1 under the drive of the conveyor belt 39, thereby realizing the palletizing operation of the resin barrel. Through the arranged conveyor belt 39, the resin barrel stacked on the pallet rack 1 can be conveyed and moved. When the resin barrel is placed on the pallet rack 1, adjusting the position of the resin barrel can prevent the next resin barrel from contacting the resin barrel below during palletizing after clamping, so that the operator improves the palletizing efficiency when palletizing the resin barrel subsequently.

[0048] In this embodiment, a push electric cylinder 6 is further arranged between the support frames 21 and the transport rack 12 on the two palletizing devices 2. The push electric cylinder 6 is fixedly arranged on the inner wall of the transport rack 12, and the telescopic end of the push electric cylinder 6 is connected to the support frame 21;

[0049] When clamping the resin barrel, after the resin barrel is located in the clamping area 13, under the drive of the push electric cylinder 6, the support frame 21 can move towards the direction of the resin barrel, so that the conveyor belt 39 on the support frame 21 can be closely attached to the outer wall of the resin barrel, thereby facilitating the clamping of the resin barrel and the subsequent conveying operation of the conveyor belt 39 on the resin barrel.

[0050] In this embodiment, the top of the transport frame 12 is also fixedly connected to a driving electric cylinder 61, and the telescopic end of the driving electric cylinder 61 is fixedly connected to a push plate 62, and the push plate 62 is clamped and connected with the movable arc plates 22 on the same side of the two stacking devices 2, and the outer walls of the movable arc plates 22 correspondingly arranged on the stacking devices 2 are fixedly connected to movable racks 63, and the side walls of the support frame 21 are rotatably connected to a rotating gear 64, and the movable racks 63 on the two movable arc plates 22 are meshed with the rotating gear 64;

[0051] When the resin barrel in the clamping area 13 is clamped, the push plate 62 is driven to move under the drive of the driving electric cylinder 61. After the push plate 62 moves, it will synchronously drive one of the movable arc plates 22 on the two stacking devices 2 to move. When one movable arc plate 22 moves, the movable rack 63 will drive the rotating gear 64 to rotate, and then drive the other movable rack 63 to move the other movable arc plate 22. The two movable arc plates 22 move relative to each other to realize the clamping operation of the resin barrel in the clamping area 13.

[0052] The use method and advantages of the present invention: The use method of the resin barrel stacking machine for unsaturated polyester resin production, the working process is as follows:

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown:

[0054] S1: When clamping the outer wall of the resin barrel, the two movable arc plates 22 move relative to each other. When the two movable arc plates 22 move, the arc groove 23 will drive the endmost side bracket 32 ​​to deflect along the arc of the arc groove 23. At this time, the two side brackets 32 move toward the outer wall of the resin barrel in the clamping area 13, so that the side brackets 32 can encircle and clamp the resin barrel in the clamping area 13;

[0055] S2: When the two movable arc plates 22 move relative to each other so that the side brackets 32 move toward the outer wall of the resin barrel, the abutment plate 48 on the endmost side bracket 32 ​​will abut against the outer wall of the resin barrel, and the inclined surface 49 at the bottom of the abutment plate 48 will squeeze the clamping plate 47, and the clamping plate 47 will move toward the direction of the connecting plate 41, and the hinge frame 43 on the outer wall of the connecting column 42 will move, so that the friction plate 45 will expand outward under the restriction of the moving groove 44 on the connecting plate 41 and fit closely with the outer wall of the resin barrel;

[0056] S3: The resin barrel is released. At this time, several side brackets 32 and the central bracket 31 return to the same axis again. The conveyor belt 39 is attached to the outer wall of the resin barrel in a parallel state, and the conveyor belt 39 is located outside the moving arc plate 22. The servo motor 34 drives the driving roller 35 to rotate, and the resin barrel attached to the conveyor belt 39 can be driven by the conveyor belt 39 to move and be conveyed in the direction of the palletizing rack 1.

[0057] S4: When clamping operation is performed on the resin barrel, after the resin barrel is located in the clamping area 13, it can be driven by the pushing electric cylinder 6 to move the support frame 21 in the direction of the resin barrel, so that the conveyor belt 39 on the support frame 21 can be closely attached to the outer wall of the resin barrel.

[0058] S5: When one moving arc plate 22 moves, the moving rack 63 will drive the rotating gear 64 to rotate, and then drive the other moving rack 63 to move the other moving arc plate 22. The relative movement of the two moving arc plates 22 realizes the clamping operation on the resin barrel in the clamping area 13.
