Abstract
Description
Technical fields:
[0001] This application relates to the field of blow molding machine technology, and in particular to a blow molding machine encapsulation robot. Background technology:
[0002] When blow molding machines produce large products, such as non-cylindrical items like pallets and tabletops, the die extrudes a tubular blank, which then requires upper and lower sealing devices to seal both ends. The blank is then extruded and blown into shape by the mold. During the sealing process, the sealing devices clamp and secure the molten, hot blank.
[0003] Our company's Chinese utility model patent application number 201920994932.0—a scissor-type material handling device for blow molding machines—includes a fixing mechanism, a lifting mechanism, a translation mechanism, and a clamping mechanism. The clamping mechanism is characterized by being horizontally positioned below a second support frame and comprising a cylinder and two symmetrically arranged first connecting rods, two second connecting rods, and two clamping rods. The cylinder barrel is fixed to the second support frame. One end of each of the two first connecting rods is hinged and fixedly connected to the cylinder's telescopic rod, and this hinge point is connected to the second support frame in a horizontally sliding manner. The other end of each first connecting rod is connected to a second connecting rod. One end of each second connecting rod is hinged to the first connecting rod, and the other end of the second connecting rod is fixedly connected to the end of the clamping rod. The end of the clamping rod connected to the second connecting rod is connected to the second support frame via a rotating shaft, allowing it to rotate around the shaft.
[0004] This patent achieves the opening and closing angle of the clamping rod by controlling the extension and retraction of the cylinder, thereby realizing the clamping and sealing action. The action stroke is short, easy to adjust and easy to control. However, due to the scissor-type opening and closing structure, it is easy to cause over-sealing at the proximal end, while the distal end can be sealed but the quality cannot be guaranteed, affecting the subsequent service life. In addition, the range of motion is limited, which cannot meet the sealing needs of products such as trays and tabletops, greatly limiting its practicality. Utility Model Content:
[0005] To solve the above-mentioned technical problems, this utility model provides a sealing robot for a blow molding machine. The technical problem it solves is that the scissor-type opening and closing structure easily leads to over-sealing at the proximal end and incomplete sealing at the distal end, affecting the subsequent service life. To solve the above-mentioned technical problems, the technical solution adopted by this utility model is:
[0006] A blow molding machine sealing robot includes:
[0007] The first support and the second support are vertically arranged in a sliding structure.
[0008] A power mechanism for driving the second support to move along the X direction, the power mechanism being connected to the first support.
[0009] The left and right clamps that seal the blank are connected to the second support in a sliding manner along the Y direction.
[0010] The sprockets and chains are connected to the second bracket via a rotating structure. The two sprockets are connected by a chain, with the lower chain fixedly connected to the left clamping plate and the upper chain fixedly connected to the right clamping plate.
[0011] A power component used to drive the left or right clamping plate to move along the Y direction.
[0012] Furthermore, the X-axis power mechanism includes a synchronous pulley, a synchronous belt, and a geared motor fixedly connected to the first bracket. The output shaft of the geared motor is connected to a synchronous pulley via a flat key. Both synchronous pulleys are connected to the first bracket via a rotating structure. One end of the synchronous belt is fixedly connected to the second bracket, and the other end of the synchronous belt passes through the two synchronous pulleys in sequence and is fixedly connected to the second bracket.
[0013] Furthermore, the first support is equipped with a support wheel for suspending the timing belt via a rotating structure.
[0014] Furthermore, both the left and right clamps are equipped with cooling pipes in a fixed structure, and the cooling pipes are equipped with water inlets and water outlets.
[0015] Furthermore, the lower end face of the cooling pipe is in contact with the upper end face of the left and right clamping plates, and the cooling pipe is arranged in a rectangular structure.
[0016] Furthermore, an inclined support plate is fixedly installed on the upper end face of the cooling pipe.
[0017] Furthermore, the outer surfaces of the left and right clamps are coated with Teflon.
[0018] Furthermore, the first support and the second support are connected by a linear guide rail.
[0019] Furthermore, both the left and right clamping plates are connected to the second bracket via linear guide rails.
[0020] Furthermore, the power component is a cylinder.

[0023] By setting up a synchronous pulley and a synchronous belt to drive the movement of the second support, control accuracy is improved and noise and vibration are reduced. Attached image description:

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:
[0029] A sealing robot for a blow molding machine includes a first support 1, a second support 2, and a power mechanism. The first support 1 and the second support 2 are vertically arranged in a sliding structure. Through the sliding cooperation of the first and second supports, the range of motion of the clamping plates is expanded, preventing the clamping plates from affecting the blank ejection from the die head, which can meet the needs of large products and improve practicality. The power mechanism is connected to the first support 1 and is used to drive the second support 2 to move along the X direction. The left clamping plate 3 and the right clamping plate 4 are used to seal the blank. The left clamping plate 3 and the right clamping plate 4 are both connected to the second support 2 in a sliding structure along the Y direction. The second support 2 is equipped with two sprockets 5 in a rotating structure. The two sprockets 5 are connected by a chain 6. The lower chain 6 is fixedly connected to the left clamping plate 3, and the upper chain 6 is fixedly connected to the right clamping plate 4. The power component 12 is used to drive the left clamping plate 3 or the right clamping plate 4 to move in the Y direction. The power component 12 is a cylinder. Through the cooperation of the sprockets 5 and the chain 6, the left clamping plate 3 and the right clamping plate 4 can be driven to move in opposite directions synchronously by one power component 12, thereby ensuring that the force at the sealing point of the blank is uniform, improving the service life. Moreover, the cooperation of the sprockets and the chain has a long transmission distance, smooth operation, and low cost.
[0030] Specifically, the feature is that the X-direction power mechanism includes a synchronous pulley 7, a synchronous belt 8, and a reduction motor fixedly connected to the first support 1. The output shaft of the reduction motor is connected to one synchronous pulley 7 via a flat key. Both synchronous pulleys 7 are connected to the first support 1 via a rotating structure. One end of the synchronous belt 8 is fixedly connected to the second support 2, and the other end of the synchronous belt 8 passes through the two synchronous pulleys 7 in sequence and is fixedly connected to the second support 2. By setting the synchronous pulley and the synchronous belt, the movement of the second support is driven, thereby improving control accuracy and reducing noise and vibration.
[0031] It should be noted that the first bracket 1 is equipped with a support wheel 9 for suspending the synchronous belt 8 through a rotating structure, which improves the structural stability.
[0032] Specifically, the first bracket 1 and the second bracket 2 are connected by a linear guide rail; the left clamping plate 3 and the right clamping plate 4 are both connected to the second bracket 2 by a linear guide rail.
[0033] It should be explained that an inclined material support plate 11 is fixedly installed on the upper end face of the cooling pipe 10. The material support plate 11 forms an angle of 20°-30° with the clamping plate. This inclined design is conducive to the product falling off when the clamp is loosened.
[0034] Based on the above embodiments, in another embodiment, the left clamping plate 3 and the right clamping plate 4 are provided with cooling pipes 10 in a fixed structure. The cooling pipes 10 are provided with water inlets and outlets. Through the flow of water, the problem of the blank sticking to the clamping plates during sealing is solved, thereby improving the product molding quality and reducing the cleaning process for workers. Specifically, the lower end face of the cooling pipe 10 is in contact with the upper end face of the left clamping plate 3 and the right clamping plate 4. The cooling pipe 10 is arranged in a rectangular structure to improve the conductivity.
[0035] The outer surfaces of the left clamp 3 and the right clamp 4 are coated with Teflon, which can effectively prevent sticking.
[0036] The working principle and process of this utility model are as follows:
[0037] When the billet needs to be sealed, the geared motor is started, which drives a synchronous pulley 7 to rotate. The synchronous pulley 7 drives the synchronous belt 8 to rotate, and the synchronous belt 8 drives the second bracket 2 to move the billet. Then, the cylinder 12 is started to retract, and the cylinder 12 drives the left clamping plate 3 to move inward. At the same time, the left clamping plate 3 drives the chain 6 to move, and the chain 6 drives the right clamping plate 4 to move inward, thereby sealing the billet. During sealing, cooling water enters the cooling pipe 10 through the water inlet and flows out through the water outlet, reducing heat and reducing adhesion.
