Description

Technical Field

[0001] The invention relates to the technical field of bottle production equipment, and more specifically to a structure for disassembling and replacing a small piston of a nozzle cylinder. Background Art

[0002] To produce qualified empty bottles, first of all, you need intact bottle blowing equipment. The movement and sealing performance of the nozzle cylinder must meet the process requirements. At the same time, ensuring good sealing can reduce the loss of high-pressure gas and reduce energy consumption. Therefore, the special parts of the nozzle seal are replaced every quarter to ensure that the produced empty bottles meet customer requirements and quality control standards. However, in the process of replacing the first-level shaft and the small piston of the nozzle cylinder, the existing disassembly method is difficult to operate. It is difficult to disassemble the small piston, which is time-consuming and labor-intensive. In addition, because there are no special tools, temporary measures such as pipe pliers are used, which can easily cause damage to the first-level shaft thread of the nozzle and damage to the surface of the small piston and the cylinder body. When the surface damage is serious, it may even cause the nozzle to leak, making the produced empty bottles not meet the requirements, seriously affecting the quality of the product.

[0003] The utility model can facilitate the disassembly and replacement of the small piston of the nozzle cylinder. Utility Model Content

[0004] The utility model aims to solve the technical problems raised by the above-mentioned background technology and provides a structure for disassembling and replacing a small piston of a nozzle cylinder, so as to facilitate the disassembly and replacement of the small piston of the nozzle cylinder.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a structure for disassembling and replacing a small piston of a nozzle cylinder, comprising: a caliper, a clamping block is arranged in the center of the front end of the caliper, a clamping hole is opened through the center of the clamping block, threaded holes are opened through the left and right sides of the clamping hole, and a fastening block is installed in the threaded hole.

[0006] A further preferred solution: the fastening block consists of a head and a tail, both of which are cylindrical. The tail of the fastening block is installed in the threaded hole, and a connecting thread is provided on the outside of the tail. The connecting thread of the tail of the fastening block fits with the threaded hole of the clamping block. The head of the fastening block is connected to the center of the top of the tail of the fastening block, and a hexagonal groove is provided in the center of the top of the head of the fastening block.

[0007] A further preferred solution is that the diameter of the head of the fastening block is mm larger than that of the tail.

[0008] A further preferred solution is that the clamping block is cylindrical in shape as a whole, and symmetrical vertical surfaces are cut at the front and rear ends of the fastening block.

[0009] A further preferred solution: the clamping block is made of rubber.

[0010] A further preferred solution is that the front end of the caliper contacts the vertical surface of the fastening block, and anti-slip teeth are provided on the contact surface between the caliper and the vertical surface.

[0011] A further preferred solution is that the diameter of the fastening block is 55 mm, the diameter of the clamping hole is 25 mm, the model of the threaded hole is M6*1.5, the interval between the centers of the threaded holes on the left and right sides of the clamping hole is 35 mm, and the height of the clamping block is 22 mm.

[0012] Beneficial effects:

[0013] 1. The clamping block is provided to achieve the effect of clamping the primary shaft. The primary shaft connected to the small piston passes through the clamping hole in the center of the clamping block, so that the clamping block is located in the center of the primary shaft. At this time, the center of the clamping block clamps the primary hole, and the primary hole is slightly larger than the size of the clamping hole. Because the clamping block is made of soft rubber material, there is a large friction force when the clamping block and the primary hole are clamped;

[0014] 2. By providing a fastening block, the clamping block can further clamp the primary shaft. When the clamping block has a primary hole in the center, the threaded hole will be deformed due to stretching, so that the threaded hole becomes elliptical. Then the tail of the fastening block is screwed into the threaded hole of the clamping block. After the tail of the fastening block enters the threaded hole, the threaded hole expands to a normal size, so that the central clamping hole clamps the primary shaft, which has a fastening effect and avoids the displacement of the primary shaft relative to the clamping block. The connecting thread at the tail of the fastening block makes it difficult for the position of the fastening block to change easily when it is installed in the threaded hole, thereby ensuring the fastening effect of the fastening block. The groove at the head of the fastening block makes it easy to screw the fastening block.

[0015] 3. In summary, the structure for disassembly and replacement of the small piston of the nozzle cylinder is provided with structures such as a clamping block and a fastening block, so that the clamping block clamps the primary shaft, which can facilitate the disassembly and replacement of the small piston of the nozzle cylinder. The caliper can disassemble the small piston by clamping the clamping block, thereby avoiding damage to the screw threads of the nozzle primary shaft caused by the caliper directly clamping the primary shaft, and avoiding slipping of the caliper when using the caliper, causing the caliper to collide with the small piston and the cylinder body, causing surface damage to the matching of the small piston and the cylinder body.

[0021] The following will be combined with the attached embodiment of the utility model Figure 1-Figure 4 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0022] See also Figure 1-4 In an embodiment of the utility model, a structure for disassembling and replacing a small piston of a nozzle cylinder includes: a caliper 3. The caliper 3 serves as a basic tool for the entire operation and is used to stably grasp the clamping block 1 so that the small piston in the nozzle cylinder can be disassembled or replaced. The clamping block 1 is located at the center of the front end of the caliper 3 and is a key component for clamping the primary shaft. A clamping hole 101 is provided in the center of the clamping block 1. The clamping hole 101 is designed to clamp the primary shaft and achieve a stable clamping. Threaded holes 102 are provided on the left and right sides of the clamping hole 101. Such a symmetrical layout ensures balanced force during tightening. The inside of the threaded hole 102 is used to install the fastening block 2. The clamping force is increased by installing the fastening block 2, thereby ensuring that the primary shaft is firmly and safely fixed.

[0023] In the embodiment of the utility model, the fastening block 2 is composed of a head 202 and a tail 203, both of which are cylindrical. The tail 203 of the fastening block 2 is installed in the threaded hole 102, and a connecting thread is provided on the outer side of the tail 203. The connecting thread of the tail 203 of the fastening block 2 is matched with the threaded hole 102 of the clamping block 1, and the head 202 of the fastening block 2 is connected to the center of the top of the tail 203 of the fastening block 2. A hexagonal groove 201 is provided in the center of the top of the head 202 of the fastening block 2. Through the connecting thread of the tail 203 of the fastening block 2, the effect of installing the fastening block 2 in the threaded hole 102 so that the position will not be easily changed is achieved, thereby ensuring the fastening effect of the fastening block 2; through the groove 201 of the head 202 of the fastening block 2, the effect of conveniently twisting the fastening block 2 is achieved.

[0024] In the embodiment of the utility model, the diameter of the head 202 of the fastening block 2 is 2 mm larger than the tail 203, so as to prevent the fastening block 2 from being over-screwed into the clamping block 1, thereby reducing the fastening effect.

[0025] In the embodiment of the utility model, the clamping block 1 is cylindrical as a whole, and symmetrical vertical surfaces 103 are cut at the front and rear ends of the fastening block 2. By designing the clamping block 1 as a whole as a cylinder, the clamping block 1 can be easily processed and formed; and the vertical surface 103 can facilitate the clamping block 1 to be clamped by the caliper 3.

[0026] In the embodiment of the utility model, the material of the clamping block 1 is rubber, so that the clamping block 1 can be deformed under the action of external force; when the clamping block 1 has a primary hole in the center, because the primary hole is slightly larger than the clamping hole 101, and because the clamping block 1 is made of soft rubber material, the threaded hole 102 can be deformed due to being stretched, and the material of rubber can make the clamping block 1 have a greater friction when clamped with the primary hole.

[0027] In the embodiment of the utility model, the front end of the caliper 3 contacts the vertical surface 103 of the fastening block 2, and anti-slip teeth are provided on the contact surface where the caliper 3 contacts the vertical surface 103, so that the caliper 3 has a greater friction force when clamping the clamping block 1, thereby avoiding the caliper 3 failing to clamp the clamping block 1, resulting in the caliper 3 being detached from the clamping block 1 and scratching the primary shaft, piston and other devices when the caliper 3 is used to remove the small piston.

[0028] In the embodiment of the utility model, the diameter of the fastening block 2 is 55mm, the diameter of the clamping hole 101 is 25mm, the model of the threaded hole 102 is M6*1.5, the interval between the centers of the threaded holes 102 on the left and right sides of the clamping hole 101 is 35mm, and the height of the clamping block 1 is 22mm, so as to achieve the effect of clarifying the shape of the fastening block 2.

[0029] Working principle: When it is necessary to replace the small piston of the nozzle cylinder of the bottle blowing equipment, first make the primary shaft connected to the small piston pass through the clamping hole 101 in the center of the clamping block 1, so that the clamping block 1 is located in the center of the primary shaft. At this time, the clamping block 1 has a primary hole in the center, and the primary hole is slightly larger than the size of the clamping hole 101. Because the clamping block 1 is made of soft rubber material, there is a large friction force when the clamping block 1 and the primary hole are clamped. At the same time, the threaded hole 102 will be deformed due to being stretched, making the threaded hole 102 become elliptical. Then, the tail of the fastening block 2 is tightened. The end 203 of the fastening block 2 is screwed into the threaded hole 102 of the clamping block 1. After the tail 203 of the fastening block 2 enters the threaded hole 102, the threaded hole 102 expands to a normal size, so that the central clamping hole 101 clamps the primary shaft, which has a fastening effect and avoids the displacement of the primary shaft relative to the clamping block 1. The connecting thread of the tail 203 of the fastening block 2 makes it possible to install the fastening block 2 in the threaded hole 102 without easily changing its position, thereby ensuring the fastening effect of the fastening block 2; the groove 201 of the head 202 of the fastening block 2 makes it easy to screw the fastening block 2.

[0030] Then align the caliper 3 with the vertical surface 103 of the clamping block 1, and squeeze the caliper 3 to clamp the column clamping block 1. Anti-slip teeth are provided on the contact surface of the caliper 3 in contact with the vertical surface 103. When the caliper clamps the clamping block 1, there is a large friction force, thereby preventing the caliper 3 from failing to clamp the clamping block 1, resulting in the caliper 3 being detached from the clamping block 1 and scratching the primary shaft, piston and other devices when the caliper 3 is used to remove the small piston. Then, pull the clamping block 1, and the clamping block 1 pulls the primary shaft, which drives the small piston to move outward, and pulls out the primary shaft together with the small piston, thereby removing the small piston. This device avoids the caliper 3 directly clamping the primary shaft, causing damage to the nozzle and primary shaft screw threads, and avoids the caliper 3 slipping when the caliper 3 is used, causing the caliper 3 to collide with the small piston and the cylinder body, causing surface damage to the matching of the small piston and the cylinder body.
