Cartridge Press Rotating Receiving Device and Push Rod Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cartridge press designs face challenges in securely attaching the receiving device to the actuation housing and efficiently managing the displacement of the push rod to express pasty masses, particularly in maintaining the pasty mass's consistency and preventing dripping during compression.
Innovation Solution
The cartridge press incorporates a rotatable receiving device with a fastening base that engages in a radial shaft, utilizing a restraint slide with a U-shaped binding flank and a compression spring for secure attachment, along with a changeover switch that allows the push-back locking member to transition between active and inactive positions to control the push rod's movement, ensuring consistent expression and preventing backflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a threaded piece is used to secure the receiving device to the actuating housing, then the receiving device can be firmly attached, but the receiving device cannot be rotated for easy cleaning
Solution Approach 1:
The receiving device is designed with a rotatable mounting base that can be rotated 360 degrees relative to the actuating housing. The mounting base includes a fastening opening that engages with a corresponding fastening element in the actuating housing, allowing the receiving device to be securely attached while maintaining rotational freedom for easy cleaning and maintenance.
2Productivity
If the push rod is freely movable, then the pasty mass can be easily expressed, but the push rod cannot prevent backflow and maintain mass consistency
Solution Approach 1:
A push-back locking member is provided that can prevent the push rod from moving backward. The locking member includes a locking surface that engages with a corresponding surface on the push rod when the push rod is in its retracted position, preventing backflow of the pasty mass and maintaining consistency during the expression process.
3Device complexity
If a simple fastening mechanism is used, then the device structure is simplified, but the receiving device cannot be securely held in position during operation
Solution Approach 1:
The fastening mechanism is segmented into a mounting base with a fastening opening and a corresponding fastening element in the actuating housing. This segmentation allows the receiving device to be securely attached while maintaining simplicity in the overall structure. The mounting base can be independently designed and manufactured, facilitating assembly and disassembly.
4Ease of operation
If the push-back locking member is always active, then the push rod cannot be manually repositioned, but if it is always inactive, then backflow cannot be prevented
Solution Approach 1:
The push-back locking member is designed to be dynamically switchable between an active locking state and an inactive state. A release lever or actuating mechanism allows the user to disengage the locking member when manual repositioning of the push rod is needed, while automatically or manually engaging it during the expression process to prevent backflow of the pasty mass.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances the secure attachment of the receiving device, maintains the pasty mass's consistency by controlling the push rod's movement, and allows for efficient expression without dripping, improving the overall functionality of the cartridge press.
Implementation Method 1
The mounting base is spring-loaded in the axial direction of the push rod by a spring
Implementation Method 2
a pressure plate attached to the end of the pressure rod is displaceable in the tube or trough, with which a hose containing the pasty mass or a piston of a cartridge is displaced in such a way that the pasty mass is pushed out

AI summary
The invention relates to a cartridge press with an actuating housing (1), comprising a lever (2), the movement thereof relative to the actuating housing (1) in an actuating direction moving a push rod (4), that is mounted such that it can be displaced in the actuator housing (1), in a push direction, and comprising receiving means (10) for receiving a pasty mass (29) that can be pressed out from a pipe or a cartridge by moving the push rod (4). The receiving means (10) is mounted so as to rotate on the actuator housing (1), wherein a securing base (11) comprising an opening (12) through which the push rod (4) passes protrudes into a securing opening (13) and is fixed, axially in relation to the push rod (4) by a positive-locking fastening means. According to the invention, the positive-locking means is formed by a securing disk (15) which is inserted into a radial shaft (14) and which engages by means of a locking flange (17) in an annular groove (16) of the securing base (11).
