AI Technical Summary

Technical Problem

In existing technologies, when BOPS/PET/PP sheets are formed and punched, the product tends to stick to the positioning block, which makes demolding difficult and prone to misalignment, affecting production efficiency and cost.

Method used

The positioning block structure is divided into two parts and connected by guide rods and springs to ensure that the product slides up and down on the positioning block, providing gaps and tension to facilitate demolding and avoid misalignment.

Benefits of technology

This enabled the product to be successfully demolded, improved production efficiency, reduced maintenance costs and labor intensity, and reduced downtime due to abnormalities.

Description

Technical Field

[0001] This utility model belongs to the field of sheet forming technology, and in particular relates to a demolding device for punching and positioning blocks of a cup making machine. Background Technology

[0002] In the existing technology, when BOPS / PET / PP sheets are punched after molding, the product is easily attached to the positioning block during punching, making it difficult to demold smoothly. The main reason is that the positioning block and the product are attached too tightly. The positioning block plays a positioning role. If it is not tight, it will cause the product to be misaligned. However, if it is too tight, it will be difficult to demold smoothly. Utility Model Content

[0003] The purpose of this utility model embodiment is to provide a demolding device for the punching positioning block of a cup making machine, which can smoothly demold the product after punching.

[0004] The present invention is implemented as follows:

[0005] The cup-making machine punching positioning block demolding device includes: an upper positioning block, a lower positioning block, a guide rod, and a spring. The upper positioning block is connected to the lower positioning block via the guide rod, which is fixed to the lower positioning block. The upper positioning block has a guide rod groove that matches the guide rod, allowing the upper positioning block to slide up and down along the guide rod. The spring is fitted onto the guide rod, with its upper end abutting against the lower end of the upper positioning block and its lower end abutting against the upper end of the lower positioning block.

[0006] The guide rods are four in number and are distributed around the lower part of the positioning block. The number of springs corresponds to the number of guide rods.

[0007] The upper and lower parts of the positioning block are integrally formed into a square positioning block.

[0008] This utility model embodiment divides the entire positioning block into two parts and sets guide rods and springs to enable the product attached to the positioning block to be demolded smoothly without product misalignment (large or small edges), thereby improving production efficiency, reducing maintenance costs and labor intensity, and greatly reducing abnormal downtime. Attached Figure Description

[0009] Figure 1 This is a structural diagram of the cup-making machine punching positioning block demolding device. Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0011] The specific implementation of this utility model will be described in detail below with reference to specific embodiments:

[0012] like Figure 1 As shown, the cup-making machine punching positioning block demolding device includes: an upper positioning block 1, a lower positioning block 4, a guide rod 2, and a spring 3. The upper positioning block is connected to the lower positioning block via the guide rod, which is fixed to the lower positioning block. The upper positioning block has a guide rod groove that matches the guide rod, allowing the upper positioning block to slide up and down along the guide rod. The spring is fitted onto the guide rod, with its upper end abutting against the lower end of the upper positioning block and its lower end abutting against the upper end of the lower positioning block.

[0013] The guide rods consist of four rods (only two are shown in the figure), distributed around the lower part of the positioning block. The number of springs corresponds to the number of guide rods. A greater number of guide rods ensures higher overall accuracy of the positioning block, maintaining stability in both the upper and lower parts.

[0014] The upper and lower parts of the positioning block are integrally formed into a square positioning block.

[0015] In this embodiment of the invention, the entire positioning block is divided into two parts, which are connected by guide rods in the middle. Springs are added to the four guide rods. In this way, the positioning block maintains the integrity of the whole, while there is a certain gap and tension in the connection between the guide rods and the springs. When punching the product, the product attached to the positioning block can be easily demolded.

[0016] This utility model embodiment divides the entire positioning block into two parts and sets guide rods and springs to enable the product attached to the positioning block to be demolded smoothly without product misalignment (large or small edges), thereby improving production efficiency, reducing maintenance costs and labor intensity, and greatly reducing abnormal downtime.

[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
